Is Acute Kidney Injury Really a Single Disease?
The search for a better biomarker than creatine for acute kidney injury (AKI) has been “long and elusive.” However, could researchers be on the right path now?
“The thinking is moving away from trying to find one biomarker that can be used for different types of kidney injury to a recognition that AKI is not just a single disease that a patient has or doesn’t have,” Rob D. Nerenz, PhD, an associate professor in the Department of Pathology and Laboratory Medicine at the Medical College of Wisconsin, Milwaukee, told this news organization. “It’s lots of different diseases that all affect the kidney in different ways.”
AKI is actually a “loose collection” of hepatorenal, cardiorenal, nephrotoxic, and sepsis-associated syndromes, as well as acute interstitial nephritis (AIN), he said. “So the question is not: ‘Is AKI present — yes or no?’ It’s: ‘What kind of AKI is present, and how do I treat it?’ ”
‘Mediocre Markers’
AKI affects about 10%-30% of hospitalized patients, according to Nerenz. It’s associated with an increased risk for adverse outcomes, including post-AKI chronic kidney disease and a mortality rate of approximately 24%.
Currently, AKI is defined by a rapid increase in serum creatinine, a decrease in urine output, or both.
“Those are mediocre markers,” Nerenz said, as serum creatinine is not very sensitive to acute change, and the increase is often detected after the therapeutic window of intervention has passed. In addition, “it only tells us that the kidneys are unhappy; it doesn’t say anything about the cause.”
Urine output is limited as a marker because many conditions affect it. “If you’re dehydrated, urine output is going to decrease,” he said. “And in some forms of AKI, urine output actually goes up.”
What’s needed, he said, is a more sensitive biomarker that’s detectable within a shorter timeframe of 2-6 hours following injury.
“Right now, we’re looking at 48 hours before a change becomes apparent, and that’s just too long. Plus, it should be kidney specific. One of the major limitations of the biomarkers that have been evaluated to this point is that, yes, they’re released by the kidney, but they’re also released by other tissue types within the body, and that hinders their effectiveness as a marker.”
Neutrophil Gelatinase-Associated Lipocalin (NGAL)
Although research on better biomarkers is ongoing, “there’s also a recognition that some of the protein markers that have been around for a while, if used appropriately, can provide value,” Nerenz said. These include, among others, NGAL.
NGAL works well in pediatric patients without other comorbidities, but it has been less useful in adult patients because it is also released by other cell types. However, recent research suggests it shows promise in patients with both cirrhosis and AKI.
There are three main causes of AKI in cirrhosis, Nerenz explained. The first is prerenal and can be primarily addressed through rehydration.
“When these patients come in, clinicians won’t do anything right away other than provide fluids. If creatinine improves over the 48-hour period of fluid replenishment, then the patient is sent home because there really isn’t extensive damage to the kidneys.”
If improvement isn’t seen after those 48 hours, then it could be one of two things: Hepatorenal syndrome or acute tubular necrosis. Patients with hepatorenal syndrome are candidates for terlipressin, which the Food and Drug Administration (FDA) approved for this indication in 2022 after it displayed notable efficacy in a double-blind study.
“You don’t want to give terlipressin to just anybody because if the issue is not a diminished blood supply to the kidney, it’s not going to help, and comes with some serious side effects, such as respiratory failure,” Nerenz explained. “Having a biomarker that can distinguish between hepatorenal syndrome and acute tubular necrosis really helps clinicians confidently identify which patients are good candidates for this drug. Right now, we’re flying blind to a certain extent, basically using clinical intuition.”
Currently, the determination of NGAL is FDA cleared only for pediatric use. One way hospitals have dealt with that is by making the test in their own labs, using appropriate reagents, validation, and so forth. These tests are then safe for use in adults but haven’t gone through the FDA approval process.
However, the FDA’s recent announcement stating that the agency should oversee lab-developed tests has made this situation unclear, Nerenz said.
“At this point, we don’t know if there’s still an opportunity to take the NGAL test (or any other cleared biomarker) and validate it for use in a different patient population. Many hospital labs simply don’t have the resources to take these tests through the whole FDA approval process.”
A New Biomarker for AIN?
Meanwhile, research is also moving forward on a better biomarker for AIN, which is also under the AKI umbrella.
“It’s important to diagnose AIN because it has a very specific treatment,” Dennis G. Moledina, MD, PhD, Yale School of Medicine in New Haven, Connecticut, told this news organization.
“AIN is caused by a bunch of different medications, such as proton pump inhibitors, cancer drugs, nonsteroidal anti-inflammatory drugs, and antibiotics, so when someone has this condition, you have to stop potentially life-saving medications and give unnecessary and potentially toxic immunosuppressive drugs, like prednisone,” he said. “If you get the diagnosis wrong, you’re stopping vital drugs and giving immunosuppression for no reason. And if you miss the diagnosis, AIN can lead to permanent chronic kidney disease.”
“Right now, the only way to diagnose AIN is to do a kidney biopsy, which is risky because it can often lead to significant bleeding,” he said. “Some people can’t undergo a biopsy because they’re on medications that increase the risk of bleeding, and they can’t be stopped.”
Furthermore, he noted, “the longer a patient takes a drug that’s causing AIN without getting a diagnosis, the less the chances of recovery because the longer you let this kidney inflammation go on, the more fibrosis and permanent damage develops. So it is important to diagnose it as early as possible, and that’s again why we have a real need for a noninvasive biomarker that can be tested rapidly.”
Moledina and colleagues have been working on identifying a suitable biomarker for close to 10 years, the latest example of which is their 2023 study validating urinary CXCL9 as just such a marker.
“We’re most excited about CXCL9 because it’s already used to diagnose some other diseases in plasma,” Moledina said. “We think that we can convince labs to test it in urine.”
In an accompanying editorial, Mark Canney, PhD, and colleagues at the University of Ottawa and The Ottawa Hospital in Ontario, Canada, wrote that the CXCL9 study findings “are exciting because they provide a road map of where diagnostics can get to for this common, yet poorly identified and treated, cause of kidney damage. The need for a different approach can be readily identified from the fact that clinicians’ gestalt for diagnosing AIN was almost tantamount to tossing a coin (AUC, 0.57). CXCL9 alone outperformed not only the clinician’s prebiopsy suspicion but also an existing diagnostic model and other candidate biomarkers both in the discovery and external validation cohorts.”
Like NGAL, CXCL9 will have to go through the FDA approval process before it can be used for AIN. Therefore, it may be a few years before it can become routinely available, Moledina said.
Nevertheless, Nerenz added, “I think the next steps for AKI are probably continuing on this path of context-dependent, selective biomarker use. I anticipate that we’ll see ongoing development in this space, just expanding to a wider variety of clinical scenarios.”
Nerenz declared receiving research funding from Abbott Labs for evaluation of an AKI biomarker. Moledina is a co-inventor on a pending patent, “Methods and Systems for Diagnosis of Acute Interstitial Nephritis”; a cofounder of the diagnostics company Predict AIN; and a consultant for Biohaven.

What Matters Most for Young Patients With CRC: Survey Highlights Top Concerns
“We tend to think of cancer as a disease of older populations, but it’s impacting younger people who are in important developmental stages of their lives,” said Samantha Savitch, MD, in a podcast from the American College of Surgeons (ACS) Clinical Congress 2024, where she presented her research.
In fact, since 1994, cases of young-onset CRC have increased by more than 50%, according to the National Cancer Institute.
“Our goal with the study was to better understand what young adults with colorectal cancer really care about, so that we can ensure that we’re properly addressing their needs as part of like comprehensive cancer care,” Savitch, with the University of Michigan, Ann Arbor, Michigan, explained.
The researchers interviewed a sample of 35 patients who were diagnosed with CRC before the age of 50 years. The researchers asked patients open-ended questions about the influence their CRC diagnosis had on their lives, the daily challenges they experienced, as well as concerns about the future.
Patients expressed the greatest concern about four areas of health and well-being: Physical health, mental health, family planning, and career.
For physical health, patients worried about incontinence, loss of vitality, and expenses related to healthcare. On the mental health front, patients expressed concern about the uncertainty surrounding long-term survival and anxiety about the timing of their diagnosis. Family planning was a key issue as well, with patients highlighting uncertainties about fertility after chemotherapy. On the career front, patients also noted concerns surrounding job security, challenges pursuing advanced degrees, and a reliance on benefits from employment.
These concerns were not gender-specific. Career, physical health, financial security, mental health, fertility, and family planning were equally important to men and women.
Savitch provided a sample of quotes from interviewees that illustrated their specific concerns in each category.
A 47-year-old man reflected on his physical health now that his rectum is gone. “I no longer have that feeling of sensation like in my cheeks; basically, the cheeks and the anus area is all dead,” he said. A 48-year-old woman discussed the havoc chemotherapy wrecked on her teeth. “I don’t want to get emotional, I just went to the dentist yesterday, and I just get so frustrated ... All these things to pay. I should be happy to be alive,” she said. But “I have so much money in my mouth.”
On the mental health front, a 34-year-old woman described the fear she felt about a cancer recurrence following the birth of her daughter. After a CT scan, she had to experience 2 weeks of limbo, thinking, “I have cancer again.” She had begun a journal dedicated to her daughter in case she had a recurrence and died. “I always think that I am going to die. I think about death every day.”
Reflecting on her future fertility, a 22-year-old woman recalled the uncertainty surrounding whether chemotherapy would affect her ability to have children. “I would get really nervous,” she said, “so I was like, ‘I will do the injections. I just want to save a few of my eggs just in case.’ ” A 33-year-old man opted not to freeze his sperm because “I didn’t know if I was going to live or die, I didn’t know anything ... I barely had any money. So, like, do I risk putting this money up to freeze something when I don’t even know if I am going to be here or not?”
On the career front, a 48-year-old man highlighted how his cancer completely changed his family’s life.”I went from being a provider for my family, making enough money to take care of my family, where my wife was staying home, to now not being able to work and her having to pick up little side jobs and stuff just to try to help make ends meet.”
“These aspects of cancer care are rarely discussed, so it is important to acknowledge that patients care about fertility and family planning, their career aspirations, building assets — all things they must put on hold because of their cancer diagnosis,” Savitch said in a news release.
“This goes beyond just colorectal cancer,” Savitch added. “There are a lot of patients experiencing similar challenges, so we need more research to better understand these issues in patients with colorectal cancer as well as other cancers and, ultimately, to restructure our comprehensive cancer programs to make sure we are treating the patient and not just the disease.”
Support for the study was provided by the Rogel Cancer Center at the University of Michigan. Savitch had no relevant disclosures.

After a CT scan, she had to experience 2 weeks of limbo, thinking, “I have cancer again.” She had begun a journal dedicated to her daughter in case she had a recurrence and died. “I always think that I am going to die. I think about death every day.”
Reflecting on her future fertility, a 22-year-old woman recalled the uncertainty surrounding whether chemotherapy would affect her ability to have children. “I would get really nervous,” she said, “so I was like, ‘I will do the injections. I just want to save a few of my eggs just in case.’ ” A 33-year-old man opted not to freeze his sperm because “I didn’t know if I was going to live or die, I didn’t know anything ... I barely had any money. So, like, do I risk putting this money up to freeze something when I don’t even know if I am going to be here or not?”
On the career front, a 48-year-old man highlighted how his cancer completely changed his family’s life.”I went from being a provider for my family, making enough money to take care of my family, where my wife was staying home, to now not being able to work and her having to pick up little side jobs and stuff just to try to help make ends meet.”
“These aspects of cancer care are rarely discussed, so it is important to acknowledge that patients care about fertility and family planning, their career aspirations, building assets — all things they must put on hold because of their cancer diagnosis,” Savitch said in a news release.
“This goes beyond just colorectal cancer,” Savitch added. “There are a lot of patients experiencing similar challenges, so we need more research to better understand these issues in patients with colorectal cancer as well as other cancers and, ultimately, to restructure our comprehensive cancer programs to make sure we are treating the patient and not just the disease.”
Support for the study was provided by the Rogel Cancer Center at the University of Michigan. Savitch had no relevant disclosures.

Are GLP-1s the Newest Fertility Treatment?
First, there were “Ozempic babies.” Now, there is also Ozempic-before-baby.
Unplanned pregnancies are still regularly being reported among people using glucagon-like peptide 1 receptor agonist (GLP-1 RA) drugs, and now fertility specialists are increasingly incorporating the medicines into preconception care plans.
The specialists say their colleagues in other areas of medicine may have an opportunity, too, to talk about weight loss using these new drugs in terms of reproductive health. Motivation and compliance can transform when the goal isn’t simply weight loss but having children.
“We have this really special moment to help patients be healthier, in order to be healthier for their kids,” said Christina Boots, MD, MSci, an associate professor of reproductive endocrinology and infertility at Northwestern University’s Feinberg School of Medicine, Chicago. “And I think that’s also a very motivating moment. It may be hard to get up and go for a run to make my jeans fit better, but when I think about it in terms of, ‘this might someday help my future daughter,’ that is a whole different level of motivation.”
Here’s why, what to know about the current lengthy list of unknowns and risks, and some options for approaching the topic with patients.
What Fertility Docs Are Doing
While overweight and obesity are consistently linked to fertility and pregnancy outcomes, Boots predicts the biggest impact of GLP-1 weight loss for fertility among women will be a specific subset: Those who are not cycling regularly, such as those with polycystic ovary syndrome (PCOS).
“The women who are cycling regularly who have very unexplained infertility and no other comorbidities like high blood pressure or something else going on, I don’t think it’s going to help their fertility very much at all,” she said “It might, but I think there’s probably something else going on in her tubes or with her eggs or his sperm, but it has nothing to do with her metabolic health.
Women who aren’t cycling regularly will benefit, but those with truly unexplained fertility probably won’t, she said.
In their recent narrative review on treating obesity and fertility with GLP-1 RAs that appeared in Fertility and Sterility, Boots and co-author Alyse S. Goldberg, MD, an endocrinologist with the University of Toronto, Ontario, Canada, advocate for the use of GLP-1s as a go-to treatment for obesity as part of preconception care by reproductive endocrinologists, calling the drugs “the most effective, least invasive means of weight loss.”
The paper is timely and necessary because use of GLP-1s is only going to increase, Patricia Jimenez, MD, an associate professor of obstetrics and gynecology at Washington University School of Medicine in St. Louis, Missouri, said in an email to this news organization.
“GLP-1 RAs are becoming a larger part of my practice. More patients are either using them already or interested in using them,” said Jimenez, who is board certified in reproductive endocrinology, obstetrics and gynecology, and obesity medicine. “I specifically see patients to discuss this and do prescribe antiobesity medications, not only GLP-1 RAs. Often this is with people with PCOS who are not planning to conceive soon or patients willing to delay fertility treatment [by] 3-6 months.”
Treating obesity is also important for women who are seeking in vitro fertilization, Boots said, because many IVF clinics have a body mass index cutoff of 40 kg/m2.
Like Jimenez’s approach, Boots and Goldberg call for comprehensive obesity care beyond the use of medication, including nutritional counseling and mental health support. Those supports are important during the transition off of GLP-1 medications, which poses a risk for rapid weight regain. That’s even with the potential support of taking metformin, which Boots often prescribes as a bridge.
Semaglutide should be stopped at least 2 months prior to conception, and tirzepatide should be stopped 1 month prior to conception, according to the manufacturers. (Boots and Goldberg listed the Canadian label recommendation for stopping tirzepatide, noting there is no suggested timeline for stopping prior to conception on the US label.)
Numerous studies have shown rapid weight regain is common when stopping GLP-1s, which presents a unique set of risks for pregnant women including early pregnancy loss, gestational diabetes, preeclampsia, and nonelective cesarean delivery.
Weighing Risks, Benefits, and Unknowns
Early looks at small human data sets, mostly involving semaglutide and earlier short-acting GLP-1s, and their impact on the risk for birth defects are “reassuring,” Boots said.
“But birth defects are just one small aspect. There’s also metabolic health and things like that long-term. Understanding what it does to the growing baby and the proximity of that medication to that growing baby is really important to see, and can’t be answered with animal studies, not perfectly anyway,” Boots said.
There are no published reports, from clinical trials nor case collections, examining the use of tirzepatide among pregnant people.
“One of the most important questions we need to answer is the preconception safety of these medications, and that includes safety for men,” Joshua Halpern, MD, MS, an adjunct assistant professor of urology at Northwestern University’s Feinberg School of Medicine, and chief scientific officer for Posterity Health, said in an email to this news organization.
“For example, a recent study found that men who were taking metformin, another popular medication for diabetes, were more likely to have children with birth defects, compared with those who were not taking the medication,” Halpern said. “Further studies are needed to determine whether a similar effect might hold true for the GLP-1 agonists.”
Small early studies on sperm are encouraging, Halpern said, suggesting that GLP-1 use may be beneficial, but a better understanding of direct effects is needed.
Among women, there may be cases where continuing use of a GLP-1 during pregnancy may offer benefits that outweigh risks, Boots suggested. Manufacturers have also created pregnancy exposure registries to measure the safety of their therapies during pregnancy.
“I have a group of patients whose sugars are so well controlled on these medications, but as soon as they come off, they get weight regain and their glucose is just so poorly controlled,” she said. “There may be a group of women where the benefits of glucose control outweigh the risks of being on the medication the whole pregnancy.”
The list of important unknowns also includes a need to examine how rapid weight loss may impact ovulation rates and spontaneous conception, as well as miscarriage rates, birth weight, and metabolic health of the child.
More detailed rebound weight gain data is coming next year, with additional analysis expected as well on birth weight and pregnancy outcomes, said Jacqueline Maya, MD, first author of the research abstract presented at this year’s American Diabetes Association conference that examined gestational weight gain among people with preexisting type 2 diabetes who were exposed to GLP-1s during pregnancy. The study included 47 exposed pregnancies (based on prescription records and electronic chart information) and compared gestational weight gain to 141 unexposed matched pregnancies. Among the exposed group, 62% exceeded recommended weight gain, compared with 41% in the unexposed group. On average, gestational weight gain in exposed pregnancies exceeded that among matched unexposed pregnancies by about 6 pounds.
The team is now working with an additional data set to examine exposed pregnancies among people with obesity, said Maya, an instructor of pediatrics at Mass General Hospital and Harvard School of Medicine. She is particularly interested in examining weight trajectories during pregnancy to see how they may affect fetal outcomes. Her team’s current project also will likely include analysis to examine other variables like postpartum weight gain and adiposity characteristics of the baby.
Maya said the team hopes to have more to report at the American Diabetes Association conference in June next year.
Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”

Digital Danger: How Cyberattacks Put Patients at Risk
On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.
In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.
In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
Healthcare Systems = ‘Soft Targets’
Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”
Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”
Because of the wealth of private data and healthcare information they maintain, hospitals are considered “high impact” for cybercriminals. Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.
The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.

Whether through a phishing email or text, password attack, or web attack, “the moment a ‘threat actor’ gets into your institution and gets credentials ... that’s the Nirvana state of a threat actor,” warned Ryan Witt, chair of the healthcare customer advisory board and vice president of Industry Solutions at Proofpoint, a cybersecurity platform. “They have those credentials and will go into deep reconnaissance mode. It often takes healthcare up to 6 months to even ascertain whether somebody’s actually in the network.” During that time, the hacker is learning how the institution works, what job functions matter, and how best to plan their attack.
“Attackers are getting in because they’re buying databases of usernames and passwords. And they’re trying them by the millions,” added Radolec. “For a sophisticated actor, all it takes is time and motivation. They have the skills. It’s just a matter of how persistent they want to be.”
Certain hospital staff are also more likely to be targeted by cyberhackers than others. “About 10% of a healthcare organization’s user base is much more vulnerable for all sorts of reasons — how they work, the value of their job title and job function, and therefore their access to systems,” said Witt.
High-profile staff are more likely to be targeted than those in lower-level positions; the so-called “CEO attack” is typical. However, staff in other hospital departments are also subject to cybercriminals, including hospice departments/hospice organizations and research arms of hospitals.
The Impact of Cyberattacks on Patients
Physicians and healthcare execs may have considered cybersecurity more of a compliance issue than a true threat to patients in the past. But this attitude is rapidly changing. “We are starting to see a very clear connection between a cyber event and how it can impact patient care and patient safety,” said Witt.
According to the Proofpoint report, cyber breaches can severely affect patient care. In 2024:
- 56% of respondents saw a delay in patient tests/procedures
- 53% experienced increased patient complications from medical procedures
- 52% noted a longer patient length of stay
- 44% saw an increase in patient transfers to other facilities
- 28% had an increase in mortality rate
What Hospitals and Physicians Can Do
Fortunately, hospitals can take measures to better protect their data and their patients. One strategy is segmenting networks to reduce the amount of data or systems one person or system can access. Educating staff about the dangers of phishing and spoofing emails also help protect organizations from ransomware attacks. Having staff avoid reusing passwords and updating logins and passwords frequently helps.
Most hospitals also need more robust security controls. Physicians and healthcare facilities must also embrace the cybersecurity controls found in other industries, said Witt. “Multifactor authentication is one of those things that can cause us frustration,” he said. “The controls can seem onerous, but they’re really valuable overall…and should become standard practice.”
Doctors can also prepare for a ransomware attack and protect patients by practicing some “old-school” medicine, like using paper systems and maintaining good patient notes — often, those notes are synced locally as well as offsite, so you’d be able to access them even during a data breach. “It’s smart to write prescriptions on pads sometimes,” said Radolec. “Don’t forget how to do those things because that will make you more resilient in the event of a ransomware attack.”
A Continuing Threat
Cyberattacks will continue. “When you look at the high likelihood [of success] and the soft target, you end up with ... a perfect storm,” said Radolec. “Hospitals have a lot of vulnerabilities. They have to keep operations going just to receive income, but also to deliver care to people.”
That means that the burden is on healthcare organizations — including physicians, nurses, staff, and C-level execs — to help keep the “security” in cybersecurity. “We are all part of the cybersecurity defense,” said Witt. Helping to maintain that defense has become a critical aspect of caring for patients.

On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.
In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.
In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
Healthcare Systems = ‘Soft Targets’
Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”
Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”
Because of the wealth of private data and healthcare information they maintain, hospitals are considered “high impact” for cybercriminals. Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.
The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.

Plastic Pollution’s Next Victim: The Human Urinary Tract
Although a 2019 World Health Organization (WHO) report concluded that microplastics in drinking water posed no risk to human health, accumulating evidence is beginning to challenge these findings.
Since plastics became widely used in the mid-20th century, they have evolved from a novel substance to an essential component in countless applications, with global production reaching 368 million tons in 2019 and expected to double by 2039. The production and degradation of plastics involve physical, chemical, and biological processes, leading to the formation of tiny fragments known as microplastics (MPs) and nanoplastics (NPs), which accumulate in the environment. Beyond the well-documented environmental harms of MPs and NPs, growing evidence of their presence within the human body raises concerns about their potential to trigger various harmful biological processes. Their detection in the urinary tract and their potential links to kidney and bladder diseases, as shown in animal studies, are particularly alarming.
Impacts Becoming Apparent
As the impact of plastic pollution becomes increasingly apparent, the need for standardized international definitions of MPs and NPs is pressing. Government publications reveal notable discrepancies between organizations in defining these fragmented plastics. The lack of consensus among regulatory bodies highlights the challenges in mitigating the environmental and health impacts of MPs and NPs. The International Organization for Standardization offers the most precise classification, defining MPs as solid, insoluble plastic particles ranging from 1 µm to 1 mm and NPs as particles smaller than 1 µm.
The intrusion of MPs and NPs into the human body, whether through inhalation, ingestion, or skin exposure (via wounds, hair follicles, or sweat glands), has been linked to harmful biological effects, including inflammation, alterations in cellular metabolism, physical cellular damage, and reduced cell viability.
Urinary Tract Plastics
The detection of MPs and NPs in the human urinary tract, combined with limited understanding of their effects, is a growing concern. An exploratory study published earlier this year aimed to systematically summarize the existing literature regarding the presence of MPs and NPs in the urinary tract and their potential consequences, guided by these research questions:
- What are the characteristics of the plastics detected in the human urinary tract?
- How are MPs and NPs defined in the current literature?
- What methodologies are used to explore the presence and effects of MPs and NPs?
- What are the pathophysiologic consequences of the presence of MPs and NPs in the human urinary tract?
For this study, the “urinary tract” included the kidneys, bladder, ureter, urethra, and urine. By focusing on the urinary tract, the study aimed to consolidate current understanding of MPs and NPs, raise awareness of this emerging issue, and lay the groundwork for further research that could contribute to public health policies and clinical practice guidelines.
The researchers conducted a scoping literature review following the recommendations of the JBI [formerly known as the Joanna Briggs Institute). They systematically searched five databases — PubMed, Scopus, CINAHL, Web of Science, and Embase — as well as gray literature sources.
Concerning Study Results
Eighteen articles were identified. The authors represent seven countries: Pakistan (n = 1), the Netherlands (n = 1), the US (n = 1), Taiwan (n = 1), Germany (n = 3), China (n = 5), and Italy (n = 6). Among these studies, six investigated and characterized the presence of MPs and NPs in the human urinary tract. MPs and NPs were detected in urine samples (n = 5), kidney cancer samples (n = 2), and bladder cancer samples (n = 1).
Additionally, 12 studies examined the effects of MPs and NPs on human urinary tract cell lines. Their findings suggest that MPs and NPs have cytotoxic effects, increase inflammation, reduce cell viability, and alter mitogen-activated protein kinase signaling pathways.
Raman spectroscopy was the primary method used to detect and characterize MPs and NPs in human samples (five out of six studies; 83%). Alternatively, pyrolysis-gas chromatography-mass spectrometry combined with direct laser infrared spectroscopy was used in one study.
Further Research Needed
This exploratory study underscores the urgent need for further research and policy development to address the challenges posed by microplastic contamination. It highlights the rapidly emerging threat of human urinary tract contamination by microplastics, questioning the WHO’s claim that microplastics pose no public health risk. The documented cytotoxic effects of microplastics, and their ability to induce inflammation, reduce cell viability, and disrupt signaling pathways, raise significant public health concerns related to bladder cancer, chronic kidney disease, chronic urinary infections, and incontinence.
Bernard-Alex Gauzere, retired physician formerly with the national health system in France (intensive care unit, tropical medicine), has disclosed no relevant financial relationships.

On the Road to Care: Travel Nurses Still in Demand
Ashly Doran has worked at seven hospitals in four states since she graduated from nursing school in 2020. No, she isn’t job-hopping. Her travel nursing assignments have ranged from level 1 trauma center emergency rooms in big cities to small medical-surgical units in the suburbs. After each 13-week assignment, Doran packs up her belongings and her cats and moves to a new post.
“Travel nursing is so flexible,” she said. “I decide where I want to go and how much I want to make and start looking for travel contracts in that area.”
Nationwide nursing shortages have forced hospitals to hire travel nurses to fill staffing gaps. During the COVID-19 pandemic, the demand for travel nurses increased by 35%. While there is still a demand for nurses to fill short-term contracts, data show that demand has declined 42% between January and July 2022 and has continued the downward trend.
“What we’re seeing now is a shift…to a pre-pandemic market,” said Rachel Neill, RN, senior clinician advocate at Vivian Health. “Travel [nursing] is not going away — there will always be a need for hospital systems and facilities to fill gaps — but hospitals have shifted more into a traditional ... operational environment.”
Traveling a Different Path
For some registered nurses (RNs), short-term assignments offer opportunities to gain experience in different facilities or explore new locations before settling into permanent positions. Even experienced RNs embrace travel nursing for the flexible schedules and opportunities to take longer breaks between contracts.
Burnout and turnover among nurses are high, and flexible schedules, including controlling when to work, are essential to sustaining a clinical nursing career. In fact, 34% of nurses called travel nursing an “ideal option” for their lifestyle, with 14% viewing it as an option for career progression.
Travel nursing is especially appealing to Millennials and Generation Z, according to Brian Weirich, RN, chief nurse innovation officer at Bon Secours Mercy Health in Cincinnati, Ohio. In fact, the average age of a travel nurse is 35 compared with an average age of 52 for all RNs.
These are generations that are more focused on reducing school loan debt and gaining experience, not 401(k) and health insurance, he said in an interview. Pay is also a factor. The average pay for travel nurses was $2588 per month, compared with $1375 for permanent staff nurses.
During the pandemic, Weirich recalls groups of nurses resigning to take travel assignments together. The RNs picked desirable locations, accepted short-term assignments, and moved together, “making top dollar in locations they wanted to explore with their best friends.”
It’s been more than a decade since Kelly Spurlock traded a permanent nursing role in Lake Placid, Florida, for short-term nursing contracts in intensive care units in 20 states.
Spurlock works with a recruiter at Ingenovis Health to secure new contracts and considers travel assignments “working vacations.” In the process of exploring new places and meeting new people, Spurlock believes that travel nursing allows her to prioritize patient care.
“I can be at the bedside and be an advocate for my patient but also keep out of the spotlight for the political part of what we do,” she explained.
The Road Ahead
The appeal of travel nursing is taking new nursing assignments in different cities and earning higher salaries, but there are downsides, too. Travel nurses often receive fewer benefits than staff nurses and end up with less favorable assignments; their levels of dissatisfaction and burnout are also higher, and their sense of work-life balance is lower than staff nurses.
Most travel contracts last between 4 and 13 weeks. Hospitals often put policies and practices in place that limit the number of back-to-back contracts that traveling nurses can accept, which means that RNs can either convert to core staff or move on to new assignments once their contract term is up.
Weirich noted that some hospitals devote considerable effort to recruiting traveling nurses to full-time roles, adding, “There are active initiatives ... to make it such a good experience that they want to stay.”
On the flip side, contracts can be terminated without notice, leaving traveling nurses scrambling to find a new assignment and a new place to live on short notice.
“You’re there as long as the hospital needs you,” said Neill. “You could sign a 12- or 15-week contract, and their needs change a month in, and ... there are budget cuts, and they can’t pay salaries anymore, so they are laying off their nurses.”
Declining demand for travel nurses has made it harder to line up back-to-back contracts. Despite being available for work, Doran once waited 6 weeks to secure a new assignment and had to live off her savings.
Spurlock believes increased competition and declining wages — pay for travel nurses declined more than 9% from January 2023 to January 2024 — have made travel nursing less attractive.
“There has been such an influx of travel nurses ... because of COVID,” said Spurlock. “The rates have now come down [and] everybody’s fighting for jobs, and ... it’s very difficult to get a job that’s paying decent money.”
Despite the challenges, Spurlock continues learning new things from each assignment and hopes to work as a travel nurse until retirement. Doran has worked at hospitals in Washington, Oregon, California, and Wisconsin and would like to add Montana, Utah, and Nevada to the list. The goal: Continue accepting assignments in different cities and states until she finds the place where she wants to put down roots.
“Nursing is a great job, but it’s a hard job [and] it can take its toll at times,” Neill said. It’s important that nurses know their goals and values to be able to find a good fitting position. “And the beauty of it is that travel can be a great way to explore and add some flexibility.”

Ashly Doran has worked at seven hospitals in four states since she graduated from nursing school in 2020. No, she isn’t job-hopping. Her travel nursing assignments have ranged from level 1 trauma center emergency rooms in big cities to small medical-surgical units in the suburbs. After each 13-week assignment, Doran packs up her belongings and her cats and moves to a new post.
“Travel nursing is so flexible,” she said. “I decide where I want to go and how much I want to make and start looking for travel contracts in that area.”
Nationwide nursing shortages have forced hospitals to hire travel nurses to fill staffing gaps. During the COVID-19 pandemic, the demand for travel nurses increased by 35%. While there is still a demand for nurses to fill short-term contracts, data show that demand has declined 42% between January and July 2022 and has continued the downward trend.
“What we’re seeing now is a shift…to a pre-pandemic market,” said Rachel Neill, RN, senior clinician advocate at Vivian Health. “Travel [nursing] is not going away — there will always be a need for hospital systems and facilities to fill gaps — but hospitals have shifted more into a traditional ... operational environment.”
Traveling a Different Path
For some registered nurses (RNs), short-term assignments offer opportunities to gain experience in different facilities or explore new locations before settling into permanent positions. Even experienced RNs embrace travel nursing for the flexible schedules and opportunities to take longer breaks between contracts.
Burnout and turnover among nurses are high, and flexible schedules, including controlling when to work, are essential to sustaining a clinical nursing career. In fact, 34% of nurses called travel nursing an “ideal option” for their lifestyle, with 14% viewing it as an option for career progression.
Travel nursing is especially appealing to Millennials and Generation Z, according to Brian Weirich, RN, chief nurse innovation officer at Bon Secours Mercy Health in Cincinnati, Ohio. In fact, the average age of a travel nurse is 35 compared with an average age of 52 for all RNs.
These are generations that are more focused on reducing school loan debt and gaining experience, not 401(k) and health insurance, he said in an interview. Pay is also a factor. The average pay for travel nurses was $2588 per month, compared with $1375 for permanent staff nurses.
During the pandemic, Weirich recalls groups of nurses resigning to take travel assignments together. The RNs picked desirable locations, accepted short-term assignments, and moved together, “making top dollar in locations they wanted to explore with their best friends.”
It’s been more than a decade since Kelly Spurlock traded a permanent nursing role in Lake Placid, Florida, for short-term nursing contracts in intensive care units in 20 states.
Spurlock works with a recruiter at Ingenovis Health to secure new contracts and considers travel assignments “working vacations.” In the process of exploring new places and meeting new people, Spurlock believes that travel nursing allows her to prioritize patient care.
“I can be at the bedside and be an advocate for my patient but also keep out of the spotlight for the political part of what we do,” she explained.
The Road Ahead
The appeal of travel nursing is taking new nursing assignments in different cities and earning higher salaries, but there are downsides, too. Travel nurses often receive fewer benefits than staff nurses and end up with less favorable assignments; their levels of dissatisfaction and burnout are also higher, and their sense of work-life balance is lower than staff nurses.
Most travel contracts last between 4 and 13 weeks. Hospitals often put policies and practices in place that limit the number of back-to-back contracts that traveling nurses can accept, which means that RNs can either convert to core staff or move on to new assignments once their contract term is up.
Weirich noted that some hospitals devote considerable effort to recruiting traveling nurses to full-time roles, adding, “There are active initiatives ... to make it such a good experience that they want to stay.”
On the flip side, contracts can be terminated without notice, leaving traveling nurses scrambling to find a new assignment and a new place to live on short notice.
“You’re there as long as the hospital needs you,” said Neill. “You could sign a 12- or 15-week contract, and their needs change a month in, and ... there are budget cuts, and they can’t pay salaries anymore, so they are laying off their nurses.”

The Bad News Behind the Rise in Locum Tenens
I’ve worked locum tenens off and on since 1982. Flexible schedules allowed me to write several books, pursue a parallel career as a medical journalist, lead medical missions in the Philippines, and develop modest expertise as an underwater photographer.
But the recent rise in locum tenens practitioners signals trouble for medicine.
A Multibillion-Dollar Industry
Roughly 52,000 US doctors work locum tenens full or part time. In annual reports by CHG Healthcare, two thirds of healthcare facilities surveyed report using locums and more than half expect to maintain or increase their use in 2024.
Another measure of the industry’s growth is that membership of The National Association of Locum Tenens Organizations (NALTO), formed in 2001 to lead this fledgling industry, has doubled since 2019. Currently, NALTO has 148 member agencies.
Why Locums?
What used to be the preserve of older physicians transitioning to retirement is now becoming a career choice. According to the 2024 Survey of Locum Tenens Physicians and Advanced Practice Professionals by AMN Healthcare, 81% of respondents said they started taking locum tenens assignments immediately after finishing medical training or in mid-career. What entices doctors to move from place to place, repeatedly adapt to new facilities and electronic medical records, live in cheap hotels, and work without paid vacations, health insurance, or retirement benefits?
Supplemental income is one reason. But the elephant in the room is clearly burnout. Rates of burnout in practicing doctors and physicians-in-training have exceeded 50%. Burnout results in medical errors, malpractice suits, and increased healthcare costs.
A recent Doximity poll of 7590 physicians revealed that 63% would not want their children to pursue a medical career. And in a Medscape survey of 7000 physicians, a third of docs under 40 would not choose medicine again if they had a do-over. If a career in medicine brings high income and privileged status, why do so many physicians regret it and discourage their children from taking the same path?
Where Is Marcus Welby, MD?
Private practice is an endangered species that no one is trying to save. According to a 2022 AMA survey, 44% of physicians owned their practices compared with 76% of physicians in the 1980s. Even fewer younger physicians are choosing private practice. Among physicians under 45 years of age, only 32% owned their practices. Most physicians are now employees, not employers. They have lost control over their duties and work hours.
In 2022, barely 13% of physicians were in solo practice. The iconic Dr Marcus Welby of the 1970s TV series has transmuted from an idealized physician to an implausible figure. (My medical students have never heard of him.)
Hospitals and health systems have purchased many private medical groups. Private-equity companies own close to 1000 physician practices and staff up to 40% of emergency rooms. For these firms, profits are paramount.
Canary in a Coal Mine
Locum tenens offers physicians unprecedented flexibility where they work, when they work, and how much they work. It provides an escape from overwhelming and unsatisfying clinical practice. While some physicians have fled to nonclinical careers, locums physicians can practice medicine without the burdens of administration, hospital politics, and ever-increasing overhead.
The locum tenens paradox is that its successful growth indicates a deteriorating traditional healthcare model. Locum tenens is not the problem, but it’s also not the solution. At best, locums is a pair of crutches that helps the current system limp along.
Healthcare is increasingly controlled by those who prioritize profit, not patients. If physicians become nothing more than complicit cogs in a dysfunctional system, burnout will fester. The profession will fail to attract the best and the brightest, the doctor shortage will increase, and the quality of patient care will decline. Everyone will suffer.
It’s already happening.

Brews, Bubbles, & Booze: Stroke Risk and Patients’ Favorite Drinks
This research roundup reviews the latest findings, highlighting both promising insights and remaining uncertainties to help guide discussions with your patients.
Coffee and Tea: Good or Bad?
In the INTERSTROKE study, high coffee consumption (> 4 cups daily) was associated with an significantly increased risk for all strokes (odds ratio [OR], 1.37) or ischemic stroke (OR, 1.31), while low to moderate coffee had no link to increased stroke risk. In contrast, tea consumption was associated with lower odds of all stroke (OR, 0.81 for highest intake) or ischemic stroke (OR, 0.81).
In a recent UK Biobank study, consumption of coffee or tea was associated with reduced risk for stroke and dementia, with the biggest benefit associated with consuming both beverages.
Specifically, the investigators found that individuals who drank two to three cups of coffee and two to three cups of tea per day had a 30% decrease in incidence of stroke and a 28% lower risk for dementia versus those who did not.
A recent systematic review and dose-response meta-analysis showed that each daily cup increase in tea was associated with an average 4% reduced risk for stroke and a 2% reduced risk for cardiovascular disease (CVD) events.
The protective effect of coffee and tea on stroke risk may be driven, in part, by flavonoids, which have antioxidant and anti-inflammatory properties, as well as positive effects on vascular function.
“The advice to patients should be that coffee and tea may protect against stroke, but that sweetening either beverage with sugar probably should be minimized,” said Cheryl Bushnell, MD, MHS, of Wake Forest University School of Medicine in Winston-Salem, North Carolina, and chair of the American Stroke Association (ASA) 2024 Guideline for the Primary Prevention of Stroke.
Taylor Wallace, PhD, a certified food scientist, said, “most people should consume a cup or two of unsweetened tea per day in moderation for cardiometabolic health. It is an easy step in the right direction for good health but not a cure-all.”
When it comes to coffee, adults who like it should drink it “in moderation — just lay off the cream and sugar,” said Wallace, adjunct associate professor at George Washington University, Washington, DC, and Tufts University, Boston, Massachusetts.
“A cup or two of black coffee with low-fat or nonfat milk with breakfast is a healthy way to start the day, especially when you’re like me and have an 8-year-old that is full of energy!” Wallace said.
The Skinny on Soda
When it comes to sugar-sweetened and diet beverages, data from the Nurses’ Health Study and Health Professionals Follow-Up Study, showed a 16% increased risk for stroke with one or more daily servings of sugar-sweetened or low-calorie soda per day (vs none), independent of established dietary and nondietary cardiovascular risk factors.
In the Women’s Health Initiative Observational Study of postmenopausal women, a higher intake of artificially sweetened beverages was associated with increased risk for all stroke (adjusted hazard ratio [aHR], 1.23), ischemic stroke (aHR, 1.31), coronary heart disease (aHR, 1.29) and all-cause mortality (aHR, 1.16).
In the Framingham Heart Study Offspring cohort, consumption of one can of diet soda or more each day (vs none) was associated with a nearly threefold increased risk for stroke and dementia over a 10-year follow-up period.
A separate French study showed that total artificial sweetener intake from all sources was associated with increased overall risk for cardiovascular and cerebrovascular disease.
However, given the limitations of these studies, it’s hard to draw any firm conclusions, Wallace cautioned.
“We know that sugar-sweetened beverages are correlated with weight gain and cardiometabolic dysfunction promotion in children and adults,” he said.
Yet, “there really isn’t any convincing evidence that diet soda has much impact on human health at all. Most observational studies are mixed and likely very confounded by other diet and lifestyle factors. That doesn’t mean go overboard; a daily diet soda is probably fine, but that doesn’t mean go drink 10 of them every day,” he added.
Alcohol: Moderation or Abstinence?
Evidence on alcohol use and stroke risk have been mixed over the years. For decades, the evidence was suggestive that a moderate amount of alcohol daily (one to two drinks in men and one drink in women) may be beneficial at reducing major vascular outcomes.
Yet, over the past few years, some research has found no evidence of benefit with moderate alcohol intake. And the detrimental effects of excessive alcohol use are clear.
A large meta-analysis showed that light to moderate alcohol consumption (up to one drink per day) was associated with a reduced risk for ischemic stroke. However, heavy drinking (more than two drinks per day) significantly increased the risk for both ischemic and hemorrhagic stroke.
A separate study showed young adults who are moderate to heavy drinkers are at increased risk for stroke — and the risk increases with more years of imbibing.
In the INTERSTROKE study, high to moderate alcohol consumption was associated with increased stroke risk, whereas low alcohol consumption conferred no increased risk.
However, Bushnell pointed out that the study data was derived from based on self-report, and that other healthy behaviors may counteract the risk for alcohol consumption.
“For alcohol, regardless of stroke risk, the most important data shows that any alcohol consumption is associated with worse cognitive function, so generally, the lower the alcohol consumption the better,” Bushnell said.
She noted that, currently, the American Heart Association (AHA)/ASA recommend a maximum of two drinks per day for men and one drink per day for women to reduce stroke risk.
“However, the data for the risk for cognitive impairment with any alcohol is convincing and should be kept in mind in addition to the maximum alcohol recommended by the AHA/ASA,” Bushnell advised.
“We know excessive intake puts you at major risk for CVD, cancer, cognitive decline, and a whole host of other health ailments — no question there,” said Wallace.
The impact of moderate intake, on the other hand, is less clear. “Alcohol is a highly biased and political issue and the evidence (or lack thereof) on both sides is shoddy at best,” Wallace added.
A key challenge is that accurate self-reporting of alcohol intake is difficult, even for scientists, and most studies rely on self-reported data from observational cohorts. These often include limited dietary assessments, which provide only a partial picture of long-term consumption patterns, Wallace noted.
“The short answer is we don’t know if moderation is beneficial, detrimental, or null with respect to health,” he said.
Bushnell reports no relevant disclosures. Wallace (www.drtaylorwallace.com) is CEO of Think Healthy Group; editor of The Journal of Dietary Supplements, deputy editor of The Journal of the American Nutrition Association (www.nutrition.org), nutrition section editor of Annals of Medicine, and an advisory board member with Forbes Health.

In the Framingham Heart Study Offspring cohort, consumption of one can of diet soda or more each day (vs none) was associated with a nearly threefold increased risk for stroke and dementia over a 10-year follow-up period.
A separate French study showed that total artificial sweetener intake from all sources was associated with increased overall risk for cardiovascular and cerebrovascular disease.
However, given the limitations of these studies, it’s hard to draw any firm conclusions, Wallace cautioned.
“We know that sugar-sweetened beverages are correlated with weight gain and cardiometabolic dysfunction promotion in children and adults,” he said.
Yet, “there really isn’t any convincing evidence that diet soda has much impact on human health at all. Most observational studies are mixed and likely very confounded by other diet and lifestyle factors. That doesn’t mean go overboard; a daily diet soda is probably fine, but that doesn’t mean go drink 10 of them every day,” he added.
Alcohol: Moderation or Abstinence?
Evidence on alcohol use and stroke risk have been mixed over the years. For decades, the evidence was suggestive that a moderate amount of alcohol daily (one to two drinks in men and one drink in women) may be beneficial at reducing major vascular outcomes.
Yet, over the past few years, some research has found no evidence of benefit with moderate alcohol intake. And the detrimental effects of excessive alcohol use are clear.
A large meta-analysis showed that light to moderate alcohol consumption (up to one drink per day) was associated with a reduced risk for ischemic stroke. However, heavy drinking (more than two drinks per day) significantly increased the risk for both ischemic and hemorrhagic stroke.
A separate study showed young adults who are moderate to heavy drinkers are at increased risk for stroke — and the risk increases with more years of imbibing.
In the INTERSTROKE study, high to moderate alcohol consumption was associated with increased stroke risk, whereas low alcohol consumption conferred no increased risk.
However, Bushnell pointed out that the study data was derived from based on self-report, and that other healthy behaviors may counteract the risk for alcohol consumption.
“For alcohol, regardless of stroke risk, the most important data shows that any alcohol consumption is associated with worse cognitive function, so generally, the lower the alcohol consumption the better,” Bushnell said.
She noted that, currently, the American Heart Association (AHA)/ASA recommend a maximum of two drinks per day for men and one drink per day for women to reduce stroke risk.
“However, the data for the risk for cognitive impairment with any alcohol is convincing and should be kept in mind in addition to the maximum alcohol recommended by the AHA/ASA,” Bushnell advised.
“We know excessive intake puts you at major risk for CVD, cancer, cognitive decline, and a whole host of other health ailments — no question there,” said Wallace.
The impact of moderate intake, on the other hand, is less clear. “Alcohol is a highly biased and political issue and the evidence (or lack thereof) on both sides is shoddy at best,” Wallace added.
A key challenge is that accurate self-reporting of alcohol intake is difficult, even for scientists, and most studies rely on self-reported data from observational cohorts. These often include limited dietary assessments, which provide only a partial picture of long-term consumption patterns, Wallace noted.
“The short answer is we don’t know if moderation is beneficial, detrimental, or null with respect to health,” he said.

This research roundup reviews the latest findings, highlighting both promising insights and remaining uncertainties to help guide discussions with your patients.
Coffee and Tea: Good or Bad?
In the INTERSTROKE study, high coffee consumption (> 4 cups daily) was associated with an significantly increased risk for all strokes (odds ratio [OR], 1.37) or ischemic stroke (OR, 1.31), while low to moderate coffee had no link to increased stroke risk. In contrast, tea consumption was associated with lower odds of all stroke (OR, 0.81 for highest intake) or ischemic stroke (OR, 0.81).
In a recent UK Biobank study, consumption of coffee or tea was associated with reduced risk for stroke and dementia, with the biggest benefit associated with consuming both beverages.
Specifically, the investigators found that individuals who drank two to three cups of coffee and two to three cups of tea per day had a 30% decrease in incidence of stroke and a 28% lower risk for dementia versus those who did not.
A recent systematic review and dose-response meta-analysis showed that each daily cup increase in tea was associated with an average 4% reduced risk for stroke and a 2% reduced risk for cardiovascular disease (CVD) events.
The protective effect of coffee and tea on stroke risk may be driven, in part, by flavonoids, which have antioxidant and anti-inflammatory properties, as well as positive effects on vascular function.
“The advice to patients should be that coffee and tea may protect against stroke, but that sweetening either beverage with sugar probably should be minimized,” said Cheryl Bushnell, MD, MHS, of Wake Forest University School of Medicine in Winston-Salem, North Carolina, and chair of the American Stroke Association (ASA) 2024 Guideline for the Primary Prevention of Stroke.
Taylor Wallace, PhD, a certified food scientist, said, “most people should consume a cup or two of unsweetened tea per day in moderation for cardiometabolic health. It is an easy step in the right direction for good health but not a cure-all.”
When it comes to coffee, adults who like it should drink it “in moderation — just lay off the cream and sugar,” said Wallace, adjunct associate professor at George Washington University, Washington, DC, and Tufts University, Boston, Massachusetts.
“A cup or two of black coffee with low-fat or nonfat milk with breakfast is a healthy way to start the day, especially when you’re like me and have an 8-year-old that is full of energy!” Wallace said.
The Skinny on Soda
When it comes to sugar-sweetened and diet beverages, data from the Nurses’ Health Study and Health Professionals Follow-Up Study, showed a 16% increased risk for stroke with one or more daily servings of sugar-sweetened or low-calorie soda per day (vs none), independent of established dietary and nondietary cardiovascular risk factors.
In the Women’s Health Initiative Observational Study of postmenopausal women, a higher intake of artificially sweetened beverages was associated with increased risk for all stroke (adjusted hazard ratio [aHR], 1.23), ischemic stroke (aHR, 1.31), coronary heart disease (aHR, 1.29) and all-cause mortality (aHR, 1.16).

Silent Epidemic: Loneliness a Serious Threat to Both Brain and Body
In a world that is more connected than ever, a silent epidemic is taking its toll. Overall, one in three US adults report chronic loneliness — a condition so detrimental that it rivals smoking and obesity with respect to its negative effect on health and well-being. From anxiety and depression to life-threatening conditions like cardiovascular disease, stroke, and Alzheimer’s and Parkinson’s diseases, loneliness is more than an emotion — it’s a serious threat to both the brain and body.
In 2023, a US Surgeon General advisory raised the alarm about the national problem of loneliness and isolation, describing it as an epidemic.
“Given the significant health consequences of loneliness and isolation, we must prioritize building social connection in the same way we have prioritized other critical public health issues such as tobacco, obesity, and substance use disorders. Together, we can build a country that’s healthier, more resilient, less lonely, and more connected,” the report concluded.
But how, exactly, does chronic loneliness affect the physiology and function of the brain? What does the latest research reveal about the link between loneliness and neurologic and psychiatric illness, and what can clinicians do to address the issue?
This news organization spoke to multiple experts in the field to explore these issues.
A Major Risk Factor
Anna Finley, PhD, assistant professor of psychology at North Dakota State University, Fargo, explained that loneliness and social isolation are different entities. Social isolation is an objective measure of the number of people someone interacts with on a regular basis, whereas loneliness is a subjective feeling that occurs when close connections are lacking.
“These two things are not actually as related as you think they would be. People can feel lonely in a crowd or feel well connected with only a few friendships. It’s more about the quality of the connection and the quality of your perception of it. So someone could be in some very supportive relationships but still feel that there’s something missing,” she said in an interview.
So what do we know about how loneliness affects health? Evidence supporting the hypothesis that loneliness is an emerging risk factor for many diseases is steadily building.
Recently, the American Heart Association published a statement summarizing the evidence for a direct association between social isolation and loneliness and coronary heart disease and stroke mortality.
In addition, many studies have shown that individuals experiencing social isolation or loneliness have an increased risk for anxiety and depression, dementia, infectious disease, hospitalization, and all-cause death, even after adjusting for age and many other traditional risk factors.
One study revealed that eliminating loneliness has the potential to prevent nearly 20% of cases of depression in adults aged 50 years or older.
Indu Subramanian, MD, professor of neurology at the University of California, Los Angeles, and colleagues conducted a study involving patients with Parkinson’s disease, which showed that the negative impact of loneliness on disease severity was as significant as the positive effects of 30 minutes of daily exercise.
“The importance of loneliness is under-recognized and undervalued, and it poses a major risk for health outcomes and quality of life,” said Subramanian.
Subramanian noted that loneliness is stigmatizing, causing people to feel unlikable and blame themselves, which prevents them from opening up to doctors or loved ones about their struggle. At the same time, healthcare providers may not think to ask about loneliness or know about potential interventions. She emphasized that much more work is needed to address this issue.
Early Mortality Risk
Julianne Holt-Lunstad, PhD, professor of psychology and neuroscience at Brigham Young University in Provo, Utah, is the author of two large meta-analyses that suggest loneliness, social isolation, or living alone are independent risk factors for early mortality, increasing this risk by about a third — the equivalent to the risk of smoking 15 cigarettes per day.
“We have quite robust evidence across a number of health outcomes implicating the harmful effects of loneliness and social isolation. While these are observational studies and show mainly associations, we do have evidence from longitudinal studies that show lacking social connection, whether that be loneliness or social isolation, predicts subsequent worse outcomes, and most of these studies have adjusted for alternative kinds of explanations, like age, initial health status, lifestyle factors,” Holt-Lunstad said.
There is some evidence to suggest that isolation is more predictive of physical health outcomes, whereas loneliness is more predictive of mental health outcomes. That said, both isolation and loneliness have significant effects on mental and physical health outcomes, she noted.
There is also the question of whether loneliness is causing poor health or whether people who are in poor health feel lonely because poor health can lead to social isolation.
Finley said there’s probably a bit of both going on, but longitudinal studies, where loneliness is measured at a fixed timepoint then health outcomes are reported a few years later, suggest that loneliness is contributing to these adverse outcomes.
She added that there is also some evidence in animal models to suggest that loneliness is a causal risk factor for adverse health outcomes. “But you can’t ask a mouse or rat how lonely they’re feeling. All you can do is house them individually — removing them from social connection. This isn’t necessarily the same thing as loneliness in humans.”
Finley is studying mechanisms in the brain that may be involved in mediating the adverse health consequences of loneliness.
“What I’ve been seeing in the data so far is that it tends to be the self-report of how lonely folks are feeling that has the associations with differences in the brain, as opposed to the number of social connections people have. It does seem to be the more subjective, emotional perception of loneliness that is important.”
In a review of potential mechanisms involved, she concluded that it is dysregulated emotions and altered perceptions of social interactions that has profound impacts on the brain, suggesting that people who are lonely may have a tendency to interpret social cues in a negative way, preventing them from forming productive positive relationships.
Lack of Trust
One researcher who has studied this phenomenon is Dirk Scheele, PhD, professor of social neuroscience at Ruhr University Bochum in Germany.
“We were interested to find out why people remained lonely,” he said in an interview. “Loneliness is an unpleasant experience, and there are so many opportunities for social contacts nowadays, it’s not really clear at first sight why people are chronically lonely.”
To examine this question, Scheele and his team conducted a study in which functional MRI was used to examine the brain in otherwise healthy individuals with high or low loneliness scores while they played a trust game.
They also simulated a positive social interaction between participants and researchers, in which they talked about plans for a fictitious lottery win, and about their hobbies and interests, during which mood was measured with questionnaires, and saliva samples were collected to measure hormone levels.
Results showed that the high-lonely individuals had reduced activation in the insula cortex during the trust decisions. “This area of the brain is involved in the processing of bodily signals, such as ‘gut feelings.’ So reduced activity here could be interpreted as fewer gut feelings on who can be trusted,” Scheele explained.
The high-lonely individuals also had reduced responsiveness to the positive social interaction with a lower release of oxytocin and a smaller elevation in mood compared with the control individuals.
Scheele pointed out that there is some evidence that oxytocin might increase trust, and there is reduced release of endogenous oxytocin in high loneliness.
“Our results are consistent with the idea that loneliness is associated with negative biases about other people. So if we expect negative things from other people — for instance, that they cannot be trusted — then that would hamper further social interactions and could lead to loneliness,” he added.
A Role for Oxytocin?
In another study, the same researchers tested short-term (five weekly sessions) group psychotherapy to reduce loneliness using established techniques to target these negative biases. They also investigated whether the effects of this group psychotherapy could be augmented by administering intranasal oxytocin (vs placebo) before the group psychotherapy sessions.
Results showed that the group psychotherapy intervention reduced trait loneliness (loneliness experienced over a prolonged period). The oxytocin did not show a significant effect on trait loneliness, but there was a suggestion that it may enhance the reduction in state loneliness (how someone is feeling at a specific time) brought about by the psychotherapy sessions.
“We found that bonding within the groups was experienced as more positive in the oxytocin treated groups. It is possible that a longer intervention would be helpful for longer-term results,” Scheele concluded. “It’s not going to be a quick fix for loneliness, but there may be a role for oxytocin as an adjunct to psychotherapy.”
A Basic Human Need
Another loneliness researcher, Livia Tomova, PhD, assistant professor of psychology at Cardiff University in Wales, has used social isolation to induce loneliness in young people and found that this intervention was linked to brain patterns similar to those associated with hunger.
“We know that the drive to eat food is a very basic human need. We know quite well how it is represented in the brain,” she explained.
The researchers tested how the brains of the participants responded to seeing pictures of social interactions after they underwent a prolonged period of social isolation. In a subsequent session, the same people were asked to undergo food fasting and then underwent brain scans when looking at pictures of food. Results showed that the neural patterns were similar in the two situations with increased activity in the substantia nigra area within the midbrain.
“This area of the brain processes rewards and motivation. It consists primarily of dopamine neurons and increased activity corresponds to a feeling of craving something. So this area of the brain that controls essential homeostatic needs is activated when people feel lonely, suggesting that our need for social contact with others is potentially a very basic need similar to eating,” Tomova said.
Lower Gray Matter Volumes in Key Brain Areas
And another group from Germany has found that higher loneliness scores are negatively associated with specific brain regions responsible for memory, emotion regulation, and social processing.
Sandra Düzel, PhD, and colleagues from the Max Planck Institute for Human Development and the Charité – Universitätsmedizin Berlin, both in Berlin, Germany, reported a study in which individuals who reported higher loneliness had smaller gray matter volumes in brain regions such as the left amygdala, anterior hippocampus, and cerebellum, regions which are crucial for both emotional regulation and higher-order cognitive processes, such as self-reflection and executive function.
Düzel believes that possible mechanisms behind the link between loneliness and brain volume differences could include stress-related damage, with prolonged loneliness associated with elevated levels of stress hormones, which can damage the hippocampus over time, and reduced cognitive and social stimulation, which may contribute to brain volume reductions in regions critical for memory and emotional processing.
“Loneliness is often characterized by reduced social and environmental diversity, leading to less engagement with novel experiences and potentially lower hippocampal-striatal connectivity.
Since novelty-seeking and environmental diversity are associated with positive emotional states, individuals experiencing loneliness might benefit from increased exposure to new environments which could stimulate the brain’s reward circuits, fostering positive affect and potentially mitigating the emotional burden of loneliness,” she said.
Is Social Prescribing the Answer?
So are there enough data now to act and attempt to develop interventions to reduce loneliness? Most of these researchers believe so.
“I think we have enough information to act on this now. There are a number of national academies consensus reports, which suggest that, while certainly there are still gaps in our evidence and more to be learned, there is sufficient evidence that a concerning portion of the population seems to lack connection, and that the consequences are serious enough that we need to do something about it,” said Holt-Lunstad.
Some countries have introduced social prescribing where doctors can prescribe a group activity or a regular visit or telephone conversation with a supportive person.
Subramanian pointed out that it’s easier to implement in countries with national health services and may be more difficult to embrace in the US healthcare system.
“We are not so encouraged from a financial perspective to think about preventive care in the US. We don’t have an easy way to recognize in any tangible way the downstream of such activities in terms of preventing future problems. That is something we need to work on,” she said.
Finley cautioned that to work well, social prescribing will require an understanding of each person’s individual situation.
“Some people may only receive benefit of interacting with others if they are also getting some sort of support to address the social and emotional concerns that are tagging along with loneliness. I’m not sure that just telling people to go join their local gardening club or whatever will be the correct answer for everyone.”
She pointed out that many people will have issues in their life that are making it hard for them to be social. These could be mobility or financial challenges, care responsibilities, or concerns about illnesses or life events. “We need to figure out what would have the most bang for the person’s buck, so to speak, as an intervention. That could mean connecting them to a group relevant to their individual situation.”
Opportunity to Connect Not Enough?
Tomova believes that training people in social skills may be a better option. “It appears that some people who are chronically lonely seem to struggle to make relationships with others. So just encouraging them to interact with others more will not necessarily help. We need to better understand the pathways involved and who are the people who become ill. We can then develop and target better interventions and teach people coping strategies for that situation.”
Scheele agreed. “While just giving people the opportunity to connect may work for some, others who are experiencing really chronic loneliness may not benefit very much from this unless their negative belief systems are addressed.” He suggested some sort of psychotherapy may be helpful in this situation.
But at least all seem to agree that healthcare providers need to be more aware of loneliness as a health risk factor, try to identify people at risk, and to think about how best to support them.
Holt-Lunstad noted that one of the recommendations in the US Surgeon General’s advisory was to increase the education, training, and resources on loneliness for healthcare providers.
“If we want this to be addressed, we need to give healthcare providers the time, resources, and training in order to do that, otherwise, we are adding one more thing to an already overburdened system. They need to understand how important it is, and how it might help them take care of the patient.”
“Our hope is that we can start to reverse some of the trends that we are seeing, both in terms of the prevalence rates of loneliness, but also that we could start seeing improvements in health and other kinds of outcomes,” she concluded.
Progress is being made in increasing awareness about the dangers of chronic loneliness. It’s now recognized as a serious health risk, but there are actionable steps that can help. Loneliness doesn’t have to be a permanent condition for anyone, said Scheele.
Holt-Lunstad served as an adviser for Foundation for Social Connection, Global Initiative on Loneliness and Connection, and Nextdoor Neighborhood Vitality Board and received research grants/income from Templeton Foundation, Eventbrite, Foundation for Social Connection, and Triple-S Foundation. Subramanian served as a speaker bureau for Acorda Pharma. The other researchers reported no disclosures.

“Loneliness is often characterized by reduced social and environmental diversity, leading to less engagement with novel experiences and potentially lower hippocampal-striatal connectivity.
Since novelty-seeking and environmental diversity are associated with positive emotional states, individuals experiencing loneliness might benefit from increased exposure to new environments which could stimulate the brain’s reward circuits, fostering positive affect and potentially mitigating the emotional burden of loneliness,” she said.
Is Social Prescribing the Answer?
So are there enough data now to act and attempt to develop interventions to reduce loneliness? Most of these researchers believe so.
“I think we have enough information to act on this now. There are a number of national academies consensus reports, which suggest that, while certainly there are still gaps in our evidence and more to be learned, there is sufficient evidence that a concerning portion of the population seems to lack connection, and that the consequences are serious enough that we need to do something about it,” said Holt-Lunstad.
Some countries have introduced social prescribing where doctors can prescribe a group activity or a regular visit or telephone conversation with a supportive person.
Subramanian pointed out that it’s easier to implement in countries with national health services and may be more difficult to embrace in the US healthcare system.
“We are not so encouraged from a financial perspective to think about preventive care in the US. We don’t have an easy way to recognize in any tangible way the downstream of such activities in terms of preventing future problems. That is something we need to work on,” she said.
Finley cautioned that to work well, social prescribing will require an understanding of each person’s individual situation.
“Some people may only receive benefit of interacting with others if they are also getting some sort of support to address the social and emotional concerns that are tagging along with loneliness. I’m not sure that just telling people to go join their local gardening club or whatever will be the correct answer for everyone.”
She pointed out that many people will have issues in their life that are making it hard for them to be social. These could be mobility or financial challenges, care responsibilities, or concerns about illnesses or life events. “We need to figure out what would have the most bang for the person’s buck, so to speak, as an intervention. That could mean connecting them to a group relevant to their individual situation.”
Opportunity to Connect Not Enough?
Tomova believes that training people in social skills may be a better option. “It appears that some people who are chronically lonely seem to struggle to make relationships with others. So just encouraging them to interact with others more will not necessarily help. We need to better understand the pathways involved and who are the people who become ill. We can then develop and target better interventions and teach people coping strategies for that situation.”
Scheele agreed. “While just giving people the opportunity to connect may work for some, others who are experiencing really chronic loneliness may not benefit very much from this unless their negative belief systems are addressed.” He suggested some sort of psychotherapy may be helpful in this situation.
But at least all seem to agree that healthcare providers need to be more aware of loneliness as a health risk factor, try to identify people at risk, and to think about how best to support them.
Holt-Lunstad noted that one of the recommendations in the US Surgeon General’s advisory was to increase the education, training, and resources on loneliness for healthcare providers.
“If we want this to be addressed, we need to give healthcare providers the time, resources, and training in order to do that, otherwise, we are adding one more thing to an already overburdened system. They need to understand how important it is, and how it might help them take care of the patient.”
“Our hope is that we can start to reverse some of the trends that we are seeing, both in terms of the prevalence rates of loneliness, but also that we could start seeing improvements in health and other kinds of outcomes,” she concluded.
Progress is being made in increasing awareness about the dangers of chronic loneliness. It’s now recognized as a serious health risk, but there are actionable steps that can help. Loneliness doesn’t have to be a permanent condition for anyone, said Scheele.
Holt-Lunstad served as an adviser for Foundation for Social Connection, Global Initiative on Loneliness and Connection, and Nextdoor Neighborhood Vitality Board and received research grants/income from Templeton Foundation, Eventbrite, Foundation for Social Connection, and Triple-S Foundation.

In a world that is more connected than ever, a silent epidemic is taking its toll. Overall, one in three US adults report chronic loneliness — a condition so detrimental that it rivals smoking and obesity with respect to its negative effect on health and well-being. From anxiety and depression to life-threatening conditions like cardiovascular disease, stroke, and Alzheimer’s and Parkinson’s diseases, loneliness is more than an emotion — it’s a serious threat to both the brain and body.
In 2023, a US Surgeon General advisory raised the alarm about the national problem of loneliness and isolation, describing it as an epidemic.
“Given the significant health consequences of loneliness and isolation, we must prioritize building social connection in the same way we have prioritized other critical public health issues such as tobacco, obesity, and substance use disorders. Together, we can build a country that’s healthier, more resilient, less lonely, and more connected,” the report concluded.
But how, exactly, does chronic loneliness affect the physiology and function of the brain? What does the latest research reveal about the link between loneliness and neurologic and psychiatric illness, and what can clinicians do to address the issue?
This news organization spoke to multiple experts in the field to explore these issues.
A Major Risk Factor
Anna Finley, PhD, assistant professor of psychology at North Dakota State University, Fargo, explained that loneliness and social isolation are different entities. Social isolation is an objective measure of the number of people someone interacts with on a regular basis, whereas loneliness is a subjective feeling that occurs when close connections are lacking.
“These two things are not actually as related as you think they would be. People can feel lonely in a crowd or feel well connected with only a few friendships. It’s more about the quality of the connection and the quality of your perception of it. So someone could be in some very supportive relationships but still feel that there’s something missing,” she said in an interview.
So what do we know about how loneliness affects health? Evidence supporting the hypothesis that loneliness is an emerging risk factor for many diseases is steadily building.
Recently, the American Heart Association published a statement summarizing the evidence for a direct association between social isolation and loneliness and coronary heart disease and stroke mortality.
In addition, many studies have shown that individuals experiencing social isolation or loneliness have an increased risk for anxiety and depression, dementia, infectious disease, hospitalization, and all-cause death, even after adjusting for age and many other traditional risk factors.
One study revealed that eliminating loneliness has the potential to prevent nearly 20% of cases of depression in adults aged 50 years or older.
Indu Subramanian, MD, professor of neurology at the University of California, Los Angeles, and colleagues conducted a study involving patients with Parkinson’s disease, which showed that the negative impact of loneliness on disease severity was as significant as the positive effects of 30 minutes of daily exercise.
“The importance of loneliness is under-recognized and undervalued, and it poses a major risk for health outcomes and quality of life,” said Subramanian.
Subramanian noted that loneliness is stigmatizing, causing people to feel unlikable and blame themselves, which prevents them from opening up to doctors or loved ones about their struggle. At the same time, healthcare providers may not think to ask about loneliness or know about potential interventions. She emphasized that much more work is needed to address this issue.
Early Mortality Risk
Julianne Holt-Lunstad, PhD, professor of psychology and neuroscience at Brigham Young University in Provo, Utah, is the author of two large meta-analyses that suggest loneliness, social isolation, or living alone are independent risk factors for early mortality, increasing this risk by about a third — the equivalent to the risk of smoking 15 cigarettes per day.
“We have quite robust evidence across a number of health outcomes implicating the harmful effects of loneliness and social isolation. While these are observational studies and show mainly associations, we do have evidence from longitudinal studies that show lacking social connection, whether that be loneliness or social isolation, predicts subsequent worse outcomes, and most of these studies have adjusted for alternative kinds of explanations, like age, initial health status, lifestyle factors,” Holt-Lunstad said.
There is some evidence to suggest that isolation is more predictive of physical health outcomes, whereas loneliness is more predictive of mental health outcomes. That said, both isolation and loneliness have significant effects on mental and physical health outcomes, she noted.
There is also the question of whether loneliness is causing poor health or whether people who are in poor health feel lonely because poor health can lead to social isolation.
Finley said there’s probably a bit of both going on, but longitudinal studies, where loneliness is measured at a fixed timepoint then health outcomes are reported a few years later, suggest that loneliness is contributing to these adverse outcomes.
She added that there is also some evidence in animal models to suggest that loneliness is a causal risk factor for adverse health outcomes. “But you can’t ask a mouse or rat how lonely they’re feeling. All you can do is house them individually — removing them from social connection. This isn’t necessarily the same thing as loneliness in humans.”
Finley is studying mechanisms in the brain that may be involved in mediating the adverse health consequences of loneliness.
“What I’ve been seeing in the data so far is that it tends to be the self-report of how lonely folks are feeling that has the associations with differences in the brain, as opposed to the number of social connections people have. It does seem to be the more subjective, emotional perception of loneliness that is important.”
In a review of potential mechanisms involved, she concluded that it is dysregulated emotions and altered perceptions of social interactions that has profound impacts on the brain, suggesting that people who are lonely may have a tendency to interpret social cues in a negative way, preventing them from forming productive positive relationships.
Lack of Trust
One researcher who has studied this phenomenon is Dirk Scheele, PhD, professor of social neuroscience at Ruhr University Bochum in Germany.
“We were interested to find out why people remained lonely,” he said in an interview. “Loneliness is an unpleasant experience, and there are so many opportunities for social contacts nowadays, it’s not really clear at first sight why people are chronically lonely.”
To examine this question, Scheele and his team conducted a study in which functional MRI was used to examine the brain in otherwise healthy individuals with high or low loneliness scores while they played a trust game.
They also simulated a positive social interaction between participants and researchers, in which they talked about plans for a fictitious lottery win, and about their hobbies and interests, during which mood was measured with questionnaires, and saliva samples were collected to measure hormone levels.
Results showed that the high-lonely individuals had reduced activation in the insula cortex during the trust decisions. “This area of the brain is involved in the processing of bodily signals, such as ‘gut feelings.’ So reduced activity here could be interpreted as fewer gut feelings on who can be trusted,” Scheele explained.
The high-lonely individuals also had reduced responsiveness to the positive social interaction with a lower release of oxytocin and a smaller elevation in mood compared with the control individuals.
Scheele pointed out that there is some evidence that oxytocin might increase trust, and there is reduced release of endogenous oxytocin in high loneliness.
“Our results are consistent with the idea that loneliness is associated with negative biases about other people. So if we expect negative things from other people — for instance, that they cannot be trusted — then that would hamper further social interactions and could lead to loneliness,” he added.
A Role for Oxytocin?
In another study, the same researchers tested short-term (five weekly sessions) group psychotherapy to reduce loneliness using established techniques to target these negative biases. They also investigated whether the effects of this group psychotherapy could be augmented by administering intranasal oxytocin (vs placebo) before the group psychotherapy sessions.
Results showed that the group psychotherapy intervention reduced trait loneliness (loneliness experienced over a prolonged period). The oxytocin did not show a significant effect on trait loneliness, but there was a suggestion that it may enhance the reduction in state loneliness (how someone is feeling at a specific time) brought about by the psychotherapy sessions.
“We found that bonding within the groups was experienced as more positive in the oxytocin treated groups. It is possible that a longer intervention would be helpful for longer-term results,” Scheele concluded. “It’s not going to be a quick fix for loneliness, but there may be a role for oxytocin as an adjunct to psychotherapy.”
A Basic Human Need
Another loneliness researcher, Livia Tomova, PhD, assistant professor of psychology at Cardiff University in Wales, has used social isolation to induce loneliness in young people and found that this intervention was linked to brain patterns similar to those associated with hunger.
“We know that the drive to eat food is a very basic human need. We know quite well how it is represented in the brain,” she explained.
The researchers tested how the brains of the participants responded to seeing pictures of social interactions after they underwent a prolonged period of social isolation. In a subsequent session, the same people were asked to undergo food fasting and then underwent brain scans when looking at pictures of food. Results showed that the neural patterns were similar in the two situations with increased activity in the substantia nigra area within the midbrain.
“This area of the brain processes rewards and motivation. It consists primarily of dopamine neurons and increased activity corresponds to a feeling of craving something. So this area of the brain that controls essential homeostatic needs is activated when people feel lonely, suggesting that our need for social contact with others is potentially a very basic need similar to eating,” Tomova said.
Lower Gray Matter Volumes in Key Brain Areas
And another group from Germany has found that higher loneliness scores are negatively associated with specific brain regions responsible for memory, emotion regulation, and social processing.
Sandra Düzel, PhD, and colleagues from the Max Planck Institute for Human Development and the Charité – Universitätsmedizin Berlin, both in Berlin, Germany, reported a study in which individuals who reported higher loneliness had smaller gray matter volumes in brain regions such as the left amygdala, anterior hippocampus, and cerebellum, regions which are crucial for both emotional regulation and higher-order cognitive processes, such as self-reflection and executive function.
Düzel believes that possible mechanisms behind the link between loneliness and brain volume differences could include stress-related damage, with prolonged loneliness associated with elevated levels of stress hormones, which can damage the hippocampus over time, and reduced cognitive and social stimulation, which may contribute to brain volume reductions in regions critical for memory and emotional processing.
“Loneliness is often characterized by reduced social and environmental diversity, leading to less engagement with novel experiences and potentially lower hippocampal-striatal connectivity.
Since novelty-seeking and environmental diversity are associated with positive emotional states, individuals experiencing loneliness might benefit from increased exposure to new environments which could stimulate the brain’s reward circuits, fostering positive affect and potentially mitigating the emotional burden of loneliness,” she said.

IBS: Understanding a Common Yet Misunderstood Condition
Irritable bowel syndrome (IBS) is one of the most common conditions encountered by both primary care providers and gastroenterologists, with a pooled global prevalence of 11.2%. This functional bowel disorder is characterized by abdominal pain or discomfort, diarrhea and/or constipation, and bloating.
Unfortunately, , according to Alan Desmond, MB, consultant in gastroenterology and general internal medicine, Torbay Hospital, UK National Health Service.
Desmond regularly sees patients who either haven’t been accurately diagnosed or have been told, “Don’t worry, it’s ‘just’ irritable bowel syndrome,” he said at the recent International Conference on Nutrition in Medicine.
A 2017 study involving nearly 2000 patients with a history of gastrointestinal (GI) symptoms found that 43.1% of those who met the criteria for IBS were undiagnosed, and among those who were diagnosed, 26% were not receiving treatment.
“Many clinicians vastly underestimate the impact functional GI symptoms have on our patients in lack of productivity, becoming homebound or losing employment, the inability to enjoy a meal with friends or family, and always needing to know where the nearest bathroom is, for example,” Desmond said in an interview.
IBS can profoundly affect patients’ mental health. One study found that 38% of patients with IBS attending a tertiary care clinic contemplated suicide because they felt hopeless about ever achieving symptom relief.
Today, several dietary, pharmacologic, and psychological/behavioral approaches are available to treat patients with IBS, noted William D. Chey, MD, AGAF, chief of the Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan.
“Each individual patient may need a different combination of these foundational treatments,” he said. “One size doesn’t fit all.”
Diagnostic Pathway
One reason IBS is so hard to diagnose is that it’s a “symptom-based disorder, with identification of the condition predicated upon certain key characteristics that are heterogeneous,” Chey said in an interview. “IBS in patient ‘A’ may not present the same way as IBS in patient ‘B,’ although there are certain foundational common characteristics.”
IBS involves “abnormalities in the motility and contractility of the GI tract,” he said. It can present with diarrhea (IBS-D), constipation (IBS-C), or a mixture or alternation of diarrhea and constipation (IBS-M).
Patients with IBS-D often have an exaggerated gastro-colonic response, while those with IBS-C often have a blunted response.
Beyond stool abnormalities and abdominal pain/discomfort, patients often report bloating/distension, low backache, lethargy, nausea, thigh pain, and urinary and gynecologic symptoms.
Historically, IBS has been regarded as a “diagnosis of exclusion” because classic diagnostic tests typically yield no concrete findings. Desmond noted that several blood tests, procedures, imaging studies, and other tests are available to rule out other organic GI conditions, as outlined in the Table.
If the patient comes from a geographical region where giardia is endemic, clinicians also should consider testing for the parasite, Chey said.
New Understanding of IBS Etiology
Now, advances in the understanding of IBS are changing the approach to the disease.
“The field is moving away from seeing IBS as a ‘wastebasket diagnosis,’ recognizing that there are other causes of a patient’s symptoms,” Mark Pimentel, MD, associate professor of medicine and gastroenterology, Cedars-Sinai, Los Angeles, said in an interview. “What’s made IBS so difficult to diagnose has been the absence of biological markers and hallmark findings on endoscopy.”
Recent research points to novel bacterial causes as culprits in the development of IBS. In particular, altered small bowel microbiota can be triggered by acute gastroenteritis.
Food poisoning can trigger the onset of IBS — a phenomenon called “postinfectious IBS (PI-IBS),” said Pimentel, who is also executive director of the Medically Associated Science and Technology Program at Cedars-Sinai. PI-IBS almost always takes the form of IBS-D, with up to 60% of patients with IBS-D suffering the long-term sequelae of food poisoning.
The types of bacteria most commonly associated with gastroenteritis are Shigella, Campylobacter, Salmonella, and Escherichia coli, Pimentel said. All of them release cytolethal distending toxin B (CdtB), causing the body to produce antibodies to the toxin.
CdtB resembles vinculin, a naturally occurring protein critical for healthy gut function. “Because of this molecular resemblance, the immune system often mistakes one for the other, producing anti-vinculin,” Pimentel explained.
This autoimmune response leads to disruptions in the gut microbiome, ultimately resulting in PI-IBS. The chain of events “doesn’t necessarily happen immediately,” Pimentel said. “You might have developed food poisoning at a party weeks or months ago.”
Acute gastroenteritis is common, affecting as many as 179 million people in the United States annually. A meta-analysis of 47 studies, incorporating 28,270 patients, found that those who had experienced acute gastroenteritis had a fourfold higher risk of developing IBS compared with nonexposed controls.
“The problem isn’t only the IBS itself, but the fact that people with PI-IBS are four times as likely to contract food poisoning again, which can further exacerbate IBS symptoms,” Pimentel said.
Diarrhea-predominant IBS can be detected through the presence of two blood biomarkers — anti-CdtB and anti-vinculin — in a blood test developed by Pimentel and his group.
“Elevation in either of these biomarkers establishes the diagnosis,” Pimentel said. “This is a breakthrough because it represents the first test that can make IBS a ‘diagnosis of inclusion.’”
The blood test also can identify IBS-M but not IBS-C.
Pimentel said that IBS-C is associated with increased levels of methanogenic archaea, which can be diagnosed by a positive methane breath test. “Methane gas slows intestinal contractility, which might result in constipation,” he said.
Diet as a Treatment Option
Diet is usually the starting point for IBS treatment, Chey said. “The standard dietary recommendations, as defined by the National Institute for Health and Care Excellence Guidance for managing IBS, are reasonable and common sense — eating three meals a day, avoiding carbonated beverages, excess alcohol, and excess caffeine, and avoiding hard-to-digest foods that can be gas producing.”
A diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs), which are carbohydrates that aren’t completely absorbed in the intestines, has been shown to be effective in alleviating GI distress in as many as 86% of patients with IBS, leading to improvements in overall GI symptoms as well as individual symptoms (eg, abdominal pain, bloating, constipation, diarrhea, and flatulence).
Desmond recommends the low FODMAP program delineated by Monash University in Australia. The diet should be undertaken only under the supervision of a dietitian, he warned. Moreover, following it on a long-term basis can have an adverse impact on dietary quality and the gut microbiome. Therefore, “it’s important to embark on stepwise reintroduction of FODMAPS under supervision to find acceptable thresholds that don’t cause a return of symptoms.”
A growing body of research suggests that following the Mediterranean diet can be helpful in reducing IBS symptoms. Chey said that some patients who tend to over-restrict their eating might benefit from a less restrictive diet than the typical low FODMAPs diet. For them, the Mediterranean diet may be a good option.
Pharmacotherapy for IBS
Nutritional approaches aren’t for everyone, Chey noted. “Some people don’t want to be on a highly restricted diet.” For them, medications addressing symptoms might be a better option.
Antispasmodics — either anticholinergics (hyoscine and dicyclomine) or smooth muscle relaxants (alverine, mebeverine, and peppermint oil) — can be helpful, although they can worsen constipation in a dose-dependent manner. It is advisable to use them on an as-needed rather than long-term basis.
Antidiarrheal agents include loperamide and diphenoxylate.
For constipation, laxatives (eg, senna, bisacodyl, polyethylene glycol, and sodium picosulfate) can be helpful.
Desmond noted that the American Gastroenterological Association does not recommend routine use of probiotics for most GI disorders, including IBS. Exceptions include prevention of Clostridioides difficile, ulcerative colitis, and pouchitis.
Targeting the Gut-Brain Relationship
Stress plays a role in exacerbating symptoms in patients with IBS and is an important target for intervention.
“If patients are living with a level of stress that’s impairing, we won’t be able to solve their gut issues until we resolve their stress issues,” Desmond said. “We need to calm the gut-microbiome-brain axis, which is multidimensional and bidirectional.”
Many people — even those without IBS — experience queasiness or diarrhea prior to a major event they’re nervous about, Chey noted. These events activate the brain, which activates the nervous system, which interacts with the GI tract. Indeed, IBS is now recognized as a disorder of gut-brain interaction, he said.
“We now know that the microbiome in the GI tract influences cognition and emotional function, depression, and anxiety. One might say that the gut is the ‘center of the universe’ to human beings,” Chey said.
Evidence-based psychological approaches for stress reduction in patients with IBS include cognitive behavioral therapy, specifically tailored to helping the patient identify associations between IBS symptoms and thoughts, emotions, and actions, as well as learning new behaviors and engaging in stress management. Psychodynamic (interpersonal) therapy enables patients to understand the connection between GI symptoms and interpersonal conflicts, emotional factors, or relationship difficulties.
Gut-directed hypnotherapy (GDH) is a “proven modality for IBS,” Desmond said. Unlike other forms of hypnotherapy, GDH focuses specifically on controlling and normalizing GI function. Studies have shown a reduction of ≥ 30% in abdominal pain in two thirds of participants, with overall response rates up to 85%. It can be delivered in an individual or group setting or via a smartphone.
Desmond recommends mindfulness-based therapy (MBT) for IBS. MBT focuses on the “cultivation of mindfulness, defined as intentional, nonjudgmental, present-focused awareness.” It has been found effective in reducing flares and the markers of gut inflammation in ulcerative colitis, as well as reducing symptoms of IBS.
Chey noted that an emerging body of literature supports the potential role of acupuncture in treating IBS, and his clinic employs it. “I would like to see further research into other areas of CAM [complementary and alternative medicine], including herbal approaches to IBS symptoms as well as stress.”
Finally, all the experts agree that more research is needed.
“The real tragedy is that the NIH invests next to nothing in IBS, in contrast to inflammatory bowel disease and many other conditions,” Pimentel said. “Yet IBS is 45 times more common than inflammatory bowel disease.”
Pimentel hopes that with enough advocacy and recognition that IBS isn’t “just stress-related,” more resources will be devoted to understanding this debilitating condition.

Acute gastroenteritis is common, affecting as many as 179 million people in the United States annually. A meta-analysis of 47 studies, incorporating 28,270 patients, found that those who had experienced acute gastroenteritis had a fourfold higher risk of developing IBS compared with nonexposed controls.
“The problem isn’t only the IBS itself, but the fact that people with PI-IBS are four times as likely to contract food poisoning again, which can further exacerbate IBS symptoms,” Pimentel said.
Diarrhea-predominant IBS can be detected through the presence of two blood biomarkers — anti-CdtB and anti-vinculin — in a blood test developed by Pimentel and his group.
“Elevation in either of these biomarkers establishes the diagnosis,” Pimentel said. “This is a breakthrough because it represents the first test that can make IBS a ‘diagnosis of inclusion.’”
The blood test also can identify IBS-M but not IBS-C.
Pimentel said that IBS-C is associated with increased levels of methanogenic archaea, which can be diagnosed by a positive methane breath test. “Methane gas slows intestinal contractility, which might result in constipation,” he said.
Diet as a Treatment Option
Diet is usually the starting point for IBS treatment, Chey said. “The standard dietary recommendations, as defined by the National Institute for Health and Care Excellence Guidance for managing IBS, are reasonable and common sense — eating three meals a day, avoiding carbonated beverages, excess alcohol, and excess caffeine, and avoiding hard-to-digest foods that can be gas producing.”
A diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs), which are carbohydrates that aren’t completely absorbed in the intestines, has been shown to be effective in alleviating GI distress in as many as 86% of patients with IBS, leading to improvements in overall GI symptoms as well as individual symptoms (eg, abdominal pain, bloating, constipation, diarrhea, and flatulence).
Desmond recommends the low FODMAP program delineated by Monash University in Australia. The diet should be undertaken only under the supervision of a dietitian, he warned. Moreover, following it on a long-term basis can have an adverse impact on dietary quality and the gut microbiome. Therefore, “it’s important to embark on stepwise reintroduction of FODMAPS under supervision to find acceptable thresholds that don’t cause a return of symptoms.”
A growing body of research suggests that following the Mediterranean diet can be helpful in reducing IBS symptoms. Chey said that some patients who tend to over-restrict their eating might benefit from a less restrictive diet than the typical low FODMAPs diet. For them, the Mediterranean diet may be a good option.
Pharmacotherapy for IBS
Nutritional approaches aren’t for everyone, Chey noted. “Some people don’t want to be on a highly restricted diet.” For them, medications addressing symptoms might be a better option.
Antispasmodics — either anticholinergics (hyoscine and dicyclomine) or smooth muscle relaxants (alverine, mebeverine, and peppermint oil) — can be helpful, although they can worsen constipation in a dose-dependent manner. It is advisable to use them on an as-needed rather than long-term basis.
Antidiarrheal agents include loperamide and diphenoxylate.
For constipation, laxatives (eg, senna, bisacodyl, polyethylene glycol, and sodium picosulfate) can be helpful.
Desmond noted that the American Gastroenterological Association does not recommend routine use of probiotics for most GI disorders, including IBS. Exceptions include prevention of Clostridioides difficile, ulcerative colitis, and pouchitis.
Targeting the Gut-Brain Relationship
Stress plays a role in exacerbating symptoms in patients with IBS and is an important target for intervention.
“If patients are living with a level of stress that’s impairing, we won’t be able to solve their gut issues until we resolve their stress issues,” Desmond said. “We need to calm the gut-microbiome-brain axis, which is multidimensional and bidirectional.”
Many people — even those without IBS — experience queasiness or diarrhea prior to a major event they’re nervous about, Chey noted. These events activate the brain, which activates the nervous system, which interacts with the GI tract. Indeed, IBS is now recognized as a disorder of gut-brain interaction, he said.
“We now know that the microbiome in the GI tract influences cognition and emotional function, depression, and anxiety. One might say that the gut is the ‘center of the universe’ to human beings,” Chey said.
Evidence-based psychological approaches for stress reduction in patients with IBS include cognitive behavioral therapy, specifically tailored to helping the patient identify associations between IBS symptoms and thoughts, emotions, and actions, as well as learning new behaviors and engaging in stress management. Psychodynamic (interpersonal) therapy enables patients to understand the connection between GI symptoms and interpersonal conflicts, emotional factors, or relationship difficulties.
Gut-directed hypnotherapy (GDH) is a “proven modality for IBS,” Desmond said. Unlike other forms of hypnotherapy, GDH focuses specifically on controlling and normalizing GI function. Studies have shown a reduction of ≥ 30% in abdominal pain in two thirds of participants, with overall response rates up to 85%. It can be delivered in an individual or group setting or via a smartphone.
Desmond recommends mindfulness-based therapy (MBT) for IBS. MBT focuses on the “cultivation of mindfulness, defined as intentional, nonjudgmental, present-focused awareness.” It has been found effective in reducing flares and the markers of gut inflammation in ulcerative colitis, as well as reducing symptoms of IBS.
Chey noted that an emerging body of literature supports the potential role of acupuncture in treating IBS, and his clinic employs it. “I would like to see further research into other areas of CAM [complementary and alternative medicine], including herbal approaches to IBS symptoms as well as stress.”
Finally, all the experts agree that more research is needed.
“The real tragedy is that the NIH invests next to nothing in IBS, in contrast to inflammatory bowel disease and many other conditions,” Pimentel said. “Yet IBS is 45 times more common than inflammatory bowel disease.”
Pimentel hopes that with enough advocacy and recognition that IBS isn’t “just stress-related,” more resources will be devoted to understanding this debilitating condition.

Irritable bowel syndrome (IBS) is one of the most common conditions encountered by both primary care providers and gastroenterologists, with a pooled global prevalence of 11.2%. This functional bowel disorder is characterized by abdominal pain or discomfort, diarrhea and/or constipation, and bloating.
Unfortunately, , according to Alan Desmond, MB, consultant in gastroenterology and general internal medicine, Torbay Hospital, UK National Health Service.
Desmond regularly sees patients who either haven’t been accurately diagnosed or have been told, “Don’t worry, it’s ‘just’ irritable bowel syndrome,” he said at the recent International Conference on Nutrition in Medicine.
A 2017 study involving nearly 2000 patients with a history of gastrointestinal (GI) symptoms found that 43.1% of those who met the criteria for IBS were undiagnosed, and among those who were diagnosed, 26% were not receiving treatment.
“Many clinicians vastly underestimate the impact functional GI symptoms have on our patients in lack of productivity, becoming homebound or losing employment, the inability to enjoy a meal with friends or family, and always needing to know where the nearest bathroom is, for example,” Desmond said in an interview.
IBS can profoundly affect patients’ mental health. One study found that 38% of patients with IBS attending a tertiary care clinic contemplated suicide because they felt hopeless about ever achieving symptom relief.
Today, several dietary, pharmacologic, and psychological/behavioral approaches are available to treat patients with IBS, noted William D. Chey, MD, AGAF, chief of the Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan.
“Each individual patient may need a different combination of these foundational treatments,” he said. “One size doesn’t fit all.”
Diagnostic Pathway
One reason IBS is so hard to diagnose is that it’s a “symptom-based disorder, with identification of the condition predicated upon certain key characteristics that are heterogeneous,” Chey said in an interview. “IBS in patient ‘A’ may not present the same way as IBS in patient ‘B,’ although there are certain foundational common characteristics.”
IBS involves “abnormalities in the motility and contractility of the GI tract,” he said. It can present with diarrhea (IBS-D), constipation (IBS-C), or a mixture or alternation of diarrhea and constipation (IBS-M).
Patients with IBS-D often have an exaggerated gastro-colonic response, while those with IBS-C often have a blunted response.
Beyond stool abnormalities and abdominal pain/discomfort, patients often report bloating/distension, low backache, lethargy, nausea, thigh pain, and urinary and gynecologic symptoms.
Historically, IBS has been regarded as a “diagnosis of exclusion” because classic diagnostic tests typically yield no concrete findings. Desmond noted that several blood tests, procedures, imaging studies, and other tests are available to rule out other organic GI conditions, as outlined in the Table.
If the patient comes from a geographical region where giardia is endemic, clinicians also should consider testing for the parasite, Chey said.
New Understanding of IBS Etiology
Now, advances in the understanding of IBS are changing the approach to the disease.
“The field is moving away from seeing IBS as a ‘wastebasket diagnosis,’ recognizing that there are other causes of a patient’s symptoms,” Mark Pimentel, MD, associate professor of medicine and gastroenterology, Cedars-Sinai, Los Angeles, said in an interview. “What’s made IBS so difficult to diagnose has been the absence of biological markers and hallmark findings on endoscopy.”
Recent research points to novel bacterial causes as culprits in the development of IBS. In particular, altered small bowel microbiota can be triggered by acute gastroenteritis.
Food poisoning can trigger the onset of IBS — a phenomenon called “postinfectious IBS (PI-IBS),” said Pimentel, who is also executive director of the Medically Associated Science and Technology Program at Cedars-Sinai. PI-IBS almost always takes the form of IBS-D, with up to 60% of patients with IBS-D suffering the long-term sequelae of food poisoning.
The types of bacteria most commonly associated with gastroenteritis are Shigella, Campylobacter, Salmonella, and Escherichia coli, Pimentel said. All of them release cytolethal distending toxin B (CdtB), causing the body to produce antibodies to the toxin.
CdtB resembles vinculin, a naturally occurring protein critical for healthy gut function. “Because of this molecular resemblance, the immune system often mistakes one for the other, producing anti-vinculin,” Pimentel explained.
This autoimmune response leads to disruptions in the gut microbiome, ultimately resulting in PI-IBS. The chain of events “doesn’t necessarily happen immediately,” Pimentel said. “You might have developed food poisoning at a party weeks or months ago.”
