A 50-year-old woman with a history of class 3 obesity, gastroesophageal reflux disease, prediabetes, metabolic dysfunction–associated steatotic liver disease, asthma, and depression returns to our weight management clinic with weight regain 4 years after Roux-en-Y gastric bypass. 

Her initial body weight was 389 lb (176.8 kg; body mass index [BMI], 65), and her nadir weight after surgery was 183 lb (83.2 kg; BMI, 30.5), representing a total weight loss of 53%. During the initial 2 years after surgery, she experienced multiple life stressors and was treated with venlafaxine for mild depression. She regained 25 lb (11.4 kg). Over the next 2 years, she gained another 20 lb (9.1 kg), for a total of 45 lb (20.5 kg) above nadir.

The patient reported increased nighttime consumption of alcohol including vodka, wine, and beer of over 20 drinks per week for the past 2 years. Her laboratory profile showed an elevated fasting glucose level (106 mg/dL, formerly 98 mg/dL), an elevated gamma-glutamyl transferase (GGT) level, and iron deficiency anemia. She admitted to regularly missing doses of postbariatric vitamins and minerals.
 

Ask Patients About Alcohol Use

It’s important to ask patients with significant weight regain after metabolic and bariatric surgery (MBS) about alcohol intake, because patients who have MBS are at an increased risk of developing alcohol use disorder (AUD).

The American Society for Metabolic and Bariatric Surgery recommends screening for alcohol intake both before and after MBS. Underreporting of alcohol consumption is common, but an elevated GGT level or elevated liver enzyme levels can indicate alcohol use. Depression and anxiety exacerbated by life stressors often accompany excessive alcohol intake.

Some antiobesity medications that regulate appetite may also help limit excessive alcohol intake. Naltrexone is used both for the treatment of AUD and for weight management, often in combination with bupropion). In a patient with weight regain and AUD, naltrexone alone would be a reasonable treatment option, although weight loss would probably be modest. The addition of bupropion to naltrexone would probably produce more weight loss; average total body weight loss with bupropion-naltrexone in clinical trials was about 6%. One cautionary note on bupropion: A patient’s seizure history should be elicited, because people with AUD are at increased risk for seizures in the withdrawal stage and bupropion can make those seizures more likely. 

Glucagon-like peptide 1 (GLP-1) receptor agonists (eg, liraglutide and semaglutide) and dual GLP-1/GIP (glucose-dependent insulinotropic polypeptide receptor agonists) (eg, tirzepatide) are second-generation antiobesity medications that produce more weight loss than first-generation agents such as bupropion/naltrexone. Of note, prior bariatric surgery was an exclusion criterion in the clinical trials assessing the efficacy of these agents for weight loss. The use of GLP-1 receptor agonists after MBS in people with inadequate weight loss or weight regain has been an area of active research. The BARI-OPTIMISE randomized clinical trial published in 2023 assessed the safety and efficacy of liraglutide 3.0 mg daily in patients with inadequate weight loss after MBS. The mean body weight reduction was 8.82% in the liraglutide group vs 0.54% in the placebo group. 

There is also emerging interest in the potential of GLP-1 receptor agonists in AUD. These medications act on the central nervous system to influence reward pathways. In rodents, studies have shown that GLP-1 receptor agonist administration reduces alcohol intake, although most studies have focused on short-term effects.

A series of experiments assessed the effects of semaglutide on alcohol intake in rodents. The authors found that semaglutide lowered the alcohol-induced release of dopamine and enhanced dopamine metabolism within the nucleus accumbens.

Evidence in humans is still limited, with only one published randomized controlled trial to date. In the 26-week study, weekly exenatide was not superior to placebo in reducing the number of heavy drinking days in patients with AUD who also received cognitive-behavioral therapy. An exploratory analysis in a subgroup of patients with obesity and AUD showed that exenatide reduced alcohol consumption. Of note, exenatide is rarely used in clinical practice because it does not produce substantial weight loss.

Liraglutide was chosen for this patient because of the established efficacy for this agent in patients with a history of MBS. In addition, patients often anecdotally report reduced desire for alcohol while taking a GLP-1 receptor agonist. Although GLP-1 receptor agonists have been shown to reduce alcohol intake in animal studies, their efficacy and safety in humans with AUD are not yet well established.
 

Back to Our Patient: 

Given the patient’s weight regain, an upper gastrointestinal series was performed to rule out gastro-gastric fistula or other anatomic abnormalities. After fistula was ruled out, she was prescribed liraglutide for weight management, which was titrated from 0.6 mg/d to 3 mg/d per the prescribing guidelines. 

With the use of liraglutide over the next year, the patient maintained a stable weight of 200 lb (90.9 kg) and noted that along with reduced appetite, her cravings for alcohol had diminished and she no longer felt the urge to drink alcohol at night. Her fasting glucose and GGT levels normalized. She began to see a nutritionist regularly and was planning to rejoin a bariatric support group.

Warning letters to primary care physicians (PCPs) regarding overprescription of quetiapine were helpful in reducing overprescribing of this agent, new research suggested.

Investigators analyzed data from an earlier trial that compared prescribing patterns in 5055 PCPs who receive a placebo letter or three warning letters informing them that their prescribing of quetiapine was high and under review by Medicare. Patients in question all had dementia and were either living in nursing homes or in the community.

The intervention reduced quetiapine use among all patients with dementia, with no detectable adverse effects on cognitive function, behavioral symptoms, depression, metabolic diagnoses, hospitalization, or death.

“This study found that overprescribing warning letters to PCPs safely reduced quetiapine prescribing to their patients with dementia,” wrote investigators led by Adam Sacarny, PhD, of the Department of Health Policy and Management, Mailman School of Public Health, Columbia University, New York. 

“This intervention and other[s] like it may be useful for future efforts to promote guideline-concordant care,” they added.

The study was published online in JAMA Network Open.
 

Off-Label Prescribing Common

The off-label use of antipsychotics in patients with dementia is fairly common, the investigators noted, affecting roughly one in seven nursing home residents and a similar number of community-dwelling older adults with dementia.

The agents are often prescribed to treat behavioral symptoms associated with dementia, including agitation and aggression. Although some evidence supports this use, antipsychotics in dementia patients can also cause an increased risk for weight gain, cognitive decline, falls and other injuries, cerebrovascular events, and mortality.

While some professional societies have called for “judicious use of antipsychotics in dementia care,” there is little evidence that reducing antipsychotic use in people with dementia might result in a benefit, investigators wrote.

The researchers analyzed data from a previous trial that focused on quetiapine, which is the most prescribed antipsychotic in the United States and is frequently used for patients with dementia.

In the original study, 2528 PCPs received a placebo letter and 2527 received three warning letters sent by the Centers for Medicare & Medicaid Services (CMS), which identified the highest-volume PCP prescribers of quetiapine.

The warning letters stated that the recipient’s quetiapine prescribing was high relative to their peers and was under review by Medicare. The placebo letter clarified an unrelated regulation. 

The current secondary analysis followed the providers and a cohort of their patients from their first receipt of the letters in 2015 through April 2017. The current evaluation analyzes patients’ outcomes through December 2018, utilizing Medicare fee-for-service claims, Minimum Data Set nursing home assessment, and Medicare enrollment data.
 

Low-Cost, Effective Intervention

While the original study focused on total quetiapine prescribing by study PCPs, the current analysis focused on patients’ total quetiapine use per 90-day period. Additional secondary outcomes included measures of cognitive function and behavioral symptoms, indicators of depression, metabolic diagnoses, indicators of use of hospital and healthcare services, and death.

PCPs in the study had a total of 84,881 patients with dementia living in nursing homes and 261,288 living in the community. At baseline, there were 92,874 patients (mean age, 82 years; 69% female).

The warning letters were associated with reduced quetiapine use among both nursing home patients and community-dwelling patients (adjusted difference, –0.7 days; P = .02 and adjusted difference, −1.5 days; P < .001, respectively).

Among nursing home patients, there were no statistically significant adverse changes in cognitive of behavioral health measures that coincided with reduction in quetiapine use.

Although a higher percentage of treatment vs control patients reported weight loss, the difference was not significant, and rates of metabolic diagnoses were similar in both groups. There were also no significant differences between the groups in emergency department use, inpatient hospital admission, or use of restraints.

Results were similar for patients living in the community.

Additionally, no adverse effects on more severe health endpoints, including rates of hospital use or entry to nursing facilities, were detected. Importantly, the risk for death was statistically significantly lower for patients whose PCPs had received warning letters vs control patients (P = .04).

The analysis “provides evidence that a low-cost letter intervention informed by behavioral science can reduce prescribing of quetiapine to patients with dementia in nursing home and community settings,” the authors wrote.

Researchers did not directly observe the administration of the medication but instead used prescription drug fills as a proxy. Moreover, they could not observe results for patients enrolled in Medicare Advantage, and claims-based and assessment-based outcomes might have been subject to measurement errors and under-ascertainment of diagnoses.

The authors received support from the National Institute on Aging. They reported no relevant financial relationships.

An online program aimed at helping those with binge-eating disorder (BED), based on completing cognitive-behavioral therapy (CBT) modules, showed positive results in a randomized, controlled trial. The findings were published in JAMA Network Open.

In the study, led by Luise Pruessner, MS, with the Department of Psychology at Heidelberg University in Germany, 154 patients (96% female; average age 35.9) who met the criteria for BED were randomized 1-to-1 to the intervention or control group.
 

12-Week CBT Program with 6 Modules

The intervention group had access to a 12-week CBT online program with a core curriculum of six mandatory modules of texts and videos, focused on self-monitoring of binge eating, psychoeducation, and regulating emotion. Each could be accessed only after the previous module was completed. Participants also chose six specialization areas to personalize the experience. Email reminders were sent to participants who delayed starting the program to boost initial and continuing engagement.

The control group had no access to the program and participants were told they were on a 12-week waiting list for it. They could explore other treatments during that time, an option that mimics real-world experiences. The design choice also helped navigate the ethics of withholding a potentially effective treatment.
 

Significant Improvement in Outcomes

The intervention group had a significant reduction in binge-eating episodes, the primary outcome, compared with the control group. In the intervention group, the average number of episodes decreased from 14.79 at baseline to 6.07 (95% confidence interval, −11.31 to −6.72; P < .001). The reduction surpassed the clinically meaningful threshold of 3.97 episodes. The control group, as expected, had no significant reductions in episodes.

The intervention group also showed improvement in outcomes including well-being, self-esteem, and emotional regulation and reductions in clinical impairment, depression, and anxiety. “However, there were no meaningful between-group differences regarding changes in work capacity,” the authors noted.

In an invited commentary, Andrea Graham, PhD, with the Center for Behavioral Intervention Technologies at the Feinberg School of Medicine, Northwestern University, Chicago, noted that BED “is a prevalent, serious, and impairing psychiatric illness.”

The study authors pointed out that BED is one of the most prevalent eating disorders, affecting “1.0% to 2.8% of the population over their lifetimes.”

Dr. Graham notes that while there are evidence-based, face-to-face psychological treatments, many patients have considerable barriers to accessing those services.
 

Digital Intervention Advantages

“Digital interventions, such as the one evaluated by Pruessner and colleagues, have the potential to curb the mental health crisis by reaching large numbers of people in need” in the moments they need help most, she wrote.

She added that with BED, eating decisions and signals for dysregulated eating occur frequently throughout the day, highlighting the need for on-demand and immediate access to self-help, like the solution Ms. Pruessner and colleagues describe.

“The importance of Pruessner and colleagues’ findings is strengthened because their digital intervention did not rely on human support for delivery,” she wrote. Relying on human intervention poses financial challenges for achieving scale.

“Therefore, self-help interventions that achieve clinically significant improvements in outcomes present an important opportunity for closing the treatment gap for binge eating. Given its effectiveness, the critical next step is to learn where and how to implement this intervention to broadly reach individuals in need,” Dr. Graham wrote.

Primary care clinicians don’t typically intervene in eating disorders and a self-help intervention might help address that gap, she added.

“However, a first step would require increasing screening for eating disorders in primary care,” Dr. Graham pointed out.

The authors report no relevant financial relationships. Dr. Graham reports grants from the National Institute of Mental Health, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), and the Agency for Healthcare Research and Quality. She reports receiving a grant from the NIDDK-funded Chicago Center for Diabetes Translation Research, Dean’s Office of the Biological Sciences Division of the University of Chicago and Feinberg School of Medicine at Northwestern University; and being an adviser to Alavida Health.

An online program aimed at helping those with binge-eating disorder (BED), based on completing cognitive-behavioral therapy (CBT) modules, showed positive results in a randomized, controlled trial. The findings were published in JAMA Network Open.

In the study, led by Luise Pruessner, MS, with the Department of Psychology at Heidelberg University in Germany, 154 patients (96% female; average age 35.9) who met the criteria for BED were randomized 1-to-1 to the intervention or control group.
 

12-Week CBT Program with 6 Modules

The intervention group had access to a 12-week CBT online program with a core curriculum of six mandatory modules of texts and videos, focused on self-monitoring of binge eating, psychoeducation, and regulating emotion. Each could be accessed only after the previous module was completed. Participants also chose six specialization areas to personalize the experience. Email reminders were sent to participants who delayed starting the program to boost initial and continuing engagement.

The control group had no access to the program and participants were told they were on a 12-week waiting list for it. They could explore other treatments during that time, an option that mimics real-world experiences. The design choice also helped navigate the ethics of withholding a potentially effective treatment.
 

Significant Improvement in Outcomes

The intervention group had a significant reduction in binge-eating episodes, the primary outcome, compared with the control group. In the intervention group, the average number of episodes decreased from 14.79 at baseline to 6.07 (95% confidence interval, −11.31 to −6.72; P < .001). The reduction surpassed the clinically meaningful threshold of 3.97 episodes. The control group, as expected, had no significant reductions in episodes.

The intervention group also showed improvement in outcomes including well-being, self-esteem, and emotional regulation and reductions in clinical impairment, depression, and anxiety. “However, there were no meaningful between-group differences regarding changes in work capacity,” the authors noted.

In an invited commentary, Andrea Graham, PhD, with the Center for Behavioral Intervention Technologies at the Feinberg School of Medicine, Northwestern University, Chicago, noted that BED “is a prevalent, serious, and impairing psychiatric illness.”

The study authors pointed out that BED is one of the most prevalent eating disorders, affecting “1.0% to 2.8% of the population over their lifetimes.”

Dr. Graham notes that while there are evidence-based, face-to-face psychological treatments, many patients have considerable barriers to accessing those services.

Contrary to previous research that suggests internet use can have a deleterious effect on mental health, a new study of more than 2 million individuals suggested it can actually enhance well-being.

Between 2006 and 2021, investigators studied more than 2 million people between the ages of 15 and 99 years in 168 countries, focusing on their psychological well-being and their use of the internet. Many of the included countries have rarely or never been studied in this connection.

Utilizing close to 34,000 different statistical models, the researchers found that almost all the analyses showed positive and statistically significant associations between internet connectivity and well-being.

“We were surprised to find a positive correlation between well-being and internet use across the majority of the thousands of models we used for our analysis,” lead author Matti Vuorre, PhD, of Tilburg University, Tilburg, the Netherlands, and a research associate at Oxford Internet Institute in England, said in a news release.

The study was published online on May 13 in Technology, Mind, and Behavior.

A Global Phenomenon

Coauthor Andrew K. Przybylski, PhD, professor of human behavior and technology at Oxford Internet Institute, explained the motive for conducting the study.

“Whilst internet technologies and their platforms and their potential psychological consequences remain debated, research to date has been inconclusive and of limited geographic and demographic scope,” he said.

He noted that the “overwhelming majority” of studies have focused on the Global North and on younger people and “ignoring the fact that the penetration of the internet has been, and continues to be, a global phenomenon.”

The researchers set out to address this gap by analyzing “how internet access, mobility internet access, and active internet use might predict psychological well-being on a global level across the life stages,” Dr. Przybylski continued. “To our knowledge, no other research has directly grappled with these issues and addressed the worldwide scope of the debate.”

To study internet use, the investigators analyzed data from the 2022 Gallup World Poll, a nationally representative survey of each country’s civilian, non-institutionalized adult population (ie, aged ≥ 15 years), conducted between 2002 and 2022. The poll assessed well-being using face-to-face, as well as phone interviews, conducted by local interviewers in the respondents’ native languages.

The total sample size included 2,414,295 adults drawn from 186 countries (53.1% women), drawn from countries that included those located in Latin America, Asia, and Africa.

The researchers examined eight indicators of well-being: life satisfaction, daily negative and positive experiences, two indices of social well-being, physical well-being, community well-being, and experiences of purpose.

Covariates included respondents’ income, education, work, relationship status, the ability to meet basic needs (food and shelter), and whether they reported having health problems.

Greater Life Satisfaction

The researchers conducted a “multiverse” of 33,792 types of analyses, researching the average differences in well-being between individuals who had access to mobile internet or had used the internet in the past 7 days.

They found that for the average country, those who had access to the internet reported approximately 0.08 units greater life satisfaction, positive experiences, and social life satisfaction and 0.06 units lower negative experience than those without access.

They also reported approximately 0.08 units greater experiences of purpose and 0.1 unit greater physical, 0.02 units greater community, and 0.08 units greater social well-being than individuals without access.

Being an active internet user was associated with a 0.03- to 0.08-unit increase in life satisfaction, positive experiences, social well-being, and physical well-being and a 0.04-unit decrease in negative experiences. Access to a smartphone predicted increases of 0.06 and 0.07 units.

Although the standard deviations (SDs) of well-being outcomes were small (eg, the median life satisfaction difference was 0.36 SDs between individuals who did and did not have access to the internet), they were “not negligible.”

In fact, when the researchers examined the associations’ robustness across all analyses, they found that 84.9% resulted in positive and statistically significant associations between internet connectivity and well-being.

Of the 4.9% of associations between internet use and community well-being that were negative, most were observed among young women between the ages of 15 and 24 years.

While the researchers did not identify this as a causal relationship, they noted that this finding is consistent with previous reports of increased cyberbullying and negative associations between social media use and depressive symptoms in young women.

“Overall, we found that average associations were consistent across internet adoption predictors and well-being outcomes, with those who had access to or actively used the internet reporting meaningfully greater well-being than those who did not,” Dr. Przybylski said.

The study’s limitations included comparing individuals with each other, given that there “are likely myriad other feature of the human condition that are associated with both uptake of internet technologies and well-being in such a manner that they might case spurious associations or mask true associations,” the authors noted.

Moreover, longitudinal studies tracking participants over time can provide more information about the “contexts of how and why an individual might be affected by internet technologies and platforms.” In addition, the self-reported measures of technology might be “lacking.”

Dr. Przybylski hopes that the findings will “bring some greater context to the screen time debate; however, further work is still needed in this important area.”

He urged platform providers “to share their detailed data on user behavior with social scientists working in this field for transparent and independent scientific enquiry, to enable a more comprehensive understanding of internet technologies in our daily lives.”

A Starting Point

In a separate news release, Kevin McConway, PhD, MBA, emeritus professor of applied statistics, The Open University, Milton Keynes, England, noted that there has been “endless debate and considerable speculation on the possible effects of internet use on well-being, in general across all ages, but more specifically in relation to children and young people.”

The current study “certainly extends the available information beyond simple speculation and beyond previous studies that used participants mostly in relatively rich Northern countries,” noted Dr. McConway, who was not involved in the study.

However, he cautioned, the study is only “a starting point, and if nothing else, it casts very serious doubt on the view, held by some people, that the internet is bad for us all.”

In particular, the observational nature of the study meant that the positive associations between internet use and measure of well-being could have been caused by other factors and are not causative.

“It’s important to understand that none of the well-being measures used in this research has been properly validated by experts in psychological measurement,” said Dr. McConway.

No source of study funding was listed. Dr. Przybylski’s research is supported by the Huo Family Foundation and the Economic and Social Research Council. In the preceding 5 years, Dr. Przybylski has worked on research grants provided by the John Fell Fund, The Diana Award, and the children’s charity Barnardo’s. These research grants were paid to Dr. Przybylski’s employer, the Oxford Internet Institute. During this period, Dr. Przybylski has engaged unpaid consultations with several organizations including UNICEF, the Organization for Economic Co-operation and Development, Meta Inc., UKIE, UK Research and Innovation, The UK’s DCMS, The Office of the UK’s Chief Medical Officer, the Office of the US Surgeon General, The UK’s Academy of Medical Sciences, and the UK Parliament. There were no financial products or benefits resulting from these consultations. Dr. Vuorre reported no relevant financial relationships. Neither author reported any conflicts of interest. Dr. McConway is a trustee of the Science Media Center. However, his remarks are in the capacity of an independent professional statistician.

Racial discrimination in Black Americans is associated with an increased risk of developing Alzheimer’s disease (AD) in later life, new findings showed.

Researchers found that Black Americans who experience racism in their 40s and 50s are more likely to have increased serum levels of AD biomarkers p-tau181 and neurofilament light (NfL) more than a decade later.

“We know that Black Americans are at an elevated risk of Alzheimer’s disease and other dementias compared to non-Hispanic White Americans, but we don’t fully understand all the factors that contribute to this disproportionate risk,” Michelle Mielke, PhD, co-author and professor of epidemiology and prevention at Wake Forest University School of Medicine, Winston-Salem, North Carolina, said in a press release.

Recent data show AD is twice as prevalent in Black Americans as in Whites, at 18.6% and 10%, respectively. Dr. Mielke said this level of disparity cannot be attributed solely to genetic differences, and evidence suggests that racism and its related stress may play a role.

The findings were published online in Alzheimer’s and Dementia.
 

AD Biomarker Testing

To further explore a possible link between exposure to racism and AD risk, investigators analyzed data from the Family and Community Health Study, a multisite, longitudinal investigation that included more than 800 families in the United States.

Blood samples and information on racial discrimination were collected from 255 middle-aged Black Americans between 2002 and 2005.

Blood samples were tested for serum phosphorylated tau181 (p-Tau181), a marker of AD pathology; NfL, a nonspecific marker of neurodegeneration; and glial fibrillary acidic protein (GFAP), a marker of brain inflammation.

Participants answered questions about racial discrimination, which included whether they have been subjected to disrespectful treatment including racial slurs, harassment from law enforcement, or if they had ever been excluded from social activities because of their race.

The sample included 212 females and 43 males with a mean age of 46. Most participants (70%) lived in urban areas.
 

Stress-Related?

Investigators found no correlation between racial discrimination and increased levels of AD blood biomarkers in 2008 when participants were a mean age of 46 years. However, 11 years later, when participants were roughly 57 years old, investigators found experiencing racism in middle age was significantly correlated with higher levels of both p-Tau181 (r = 0.158; P ≤ .012) and NfL (r = 0.143; P ≤ .023). There was no significant association between reported discrimination and GFAP.

“These findings support the hypothesis that unique life stressors encountered by Black Americans in midlife become biologically embedded and contribute to AD pathology and neurodegeneration later in life,” the authors wrote.

Investigators speculated based on previous research that the stress related to discrimination may be associated with reductions in hippocampal and prefrontal cortex volumes and neurodegeneration in general.

Dr. Mielke also said it’s clear that future studies should focus on racism experienced by Black Americans to further understand their risk for dementia.

“This research can help inform policies and interventions to reduce racial disparities and reduce dementia risk,” she said.

Study limitations include the absence of amyloid biomarkers. Investigators noted that participants had non-detectable levels of amyloid, likely due to the use of serum vs cerebrospinal fluid.

The study was funded by the National Institute on Aging and the National Heart, Lung, and Blood Institute. Mielke reported serving on scientific advisory boards and/or having consulted for Acadia, Biogen, Eisai, LabCorp, Lilly, Merck, PeerView Institute, Roche, Siemens Healthineers, and Sunbird Bio.

Racial discrimination in Black Americans is associated with an increased risk of developing Alzheimer’s disease (AD) in later life, new findings showed.

Researchers found that Black Americans who experience racism in their 40s and 50s are more likely to have increased serum levels of AD biomarkers p-tau181 and neurofilament light (NfL) more than a decade later.

“We know that Black Americans are at an elevated risk of Alzheimer’s disease and other dementias compared to non-Hispanic White Americans, but we don’t fully understand all the factors that contribute to this disproportionate risk,” Michelle Mielke, PhD, co-author and professor of epidemiology and prevention at Wake Forest University School of Medicine, Winston-Salem, North Carolina, said in a press release.

Recent data show AD is twice as prevalent in Black Americans as in Whites, at 18.6% and 10%, respectively. Dr. Mielke said this level of disparity cannot be attributed solely to genetic differences, and evidence suggests that racism and its related stress may play a role.

The findings were published online in Alzheimer’s and Dementia.
 

AD Biomarker Testing

To further explore a possible link between exposure to racism and AD risk, investigators analyzed data from the Family and Community Health Study, a multisite, longitudinal investigation that included more than 800 families in the United States.

Blood samples and information on racial discrimination were collected from 255 middle-aged Black Americans between 2002 and 2005.

Blood samples were tested for serum phosphorylated tau181 (p-Tau181), a marker of AD pathology; NfL, a nonspecific marker of neurodegeneration; and glial fibrillary acidic protein (GFAP), a marker of brain inflammation.

Participants answered questions about racial discrimination, which included whether they have been subjected to disrespectful treatment including racial slurs, harassment from law enforcement, or if they had ever been excluded from social activities because of their race.

The sample included 212 females and 43 males with a mean age of 46. Most participants (70%) lived in urban areas.

Clinicians interested in treating patients with symptoms of mild cognitive impairment or mild dementia should carefully analyze the potential benefits and harms of monoclonal amyloid beta therapy, including likelihood of side effects and overall burden on the patient, according to researchers at the annual meeting of the American Geriatrics Society (AGS). 

Lecanemab (Leqembi) may help some patients by lowering the level of beta-amyloid protein in the brain. Results from a phase 3 trial presented at the conference showed participants with Alzheimer’s disease had a 27% slower progression of the disease compared with placebo.

But clinicians must weigh that advantage against risks and contraindications, according to Esther Oh, MD, PhD, an associate professor in the Division of Geriatric Medicine and Gerontology and co-director of the Johns Hopkins Memory and Alzheimer’s Treatment Center, Johns Hopkins University, Baltimore, Maryland, who spoke during a plenary session. Lecanemab gained accelerated approval by the US Food and Drug Administration in January 2023 and full approval in July 2023.

The results from CLARITY, an 18-month, multicenter, double-blind trial involving 1795 participants aged 50-90 years, showed that the variation between treatment and placebo did not meet the criteria for a minimum clinically important difference for mild cognitive impairment or mild Alzheimer’s disease.

Even more concerning to Dr. Oh was the rate of amyloid-related abnormalities on brain imaging, which can cause brain edema and hemorrhage (12.6% and 17.3%, respectively). Almost 85% of cases were asymptomatic. 

The risk for abnormalities indicates that thrombolytics are contraindicated for patients taking the drug, according to Dr. Oh. 

“Appropriate use recommendations exclude vitamin K antagonists such as warfarin, direct oral anticoagulants and heparin, although aspirin and other antiplatelet agents are allowed,” Dr. Oh said during the presentation.

Blood biomarkers, PET imaging, and levels of amyloid-beta proteins in cerebrospinal fluid are used to determine eligibility for lecanemab. However, tau biomarkers may indicate signs of cognitive impairment decades prior to symptoms. Some evidence indicates that the drug may be more effective in individuals with low tau levels that are evident in earlier stages of disease. Tau can also be determined from cerebrospinal fluid, however, “we do not factor in tau protein as a biomarker for treatment eligibility, but this may become an important biomarker in the future,” Dr. Oh said.

Lecanemab is cost-prohibitive for many patients, with an annual price tag of $26,000. Treatment also requires monthly infusions, a PET, intravenous administration, lab work, multiple MRIs, and potentially an APOE4 serum test.

Medicare covers the majority of services, but patients are responsible for deductibles and copays, an estimated $7000 annually, according to Shari Ling, MD, deputy chief medical officer with the US Centers for Medicare & Medicaid Services, who also spoke during the session. Supplemental or other insurance such as Medicaid are also not included in this estimate.

The Medicare population is growing more complex over time, Dr. Ling said. In 2021, 54% of beneficiaries had five or more comorbidities, which can affect eligibility for lecanemab. 

“Across the healthcare system, we are learning what is necessary for coordination of delivery, for evaluation of people who receive these treatments, and for the care that is not anticipated,” Dr. Ling noted.

Neither speaker reported any financial conflicts of interest.

Cognitive-behavioral therapy (CBT) is superior to mindfulness-based cognitive therapy (MT) for reducing symptom severity in patients with prolonged grief disorder, results from a randomized trial showed.

While patients receiving grief-focused CBT had a superior response compared with those receiving MT, participants in both groups experienced a significant reduction in symptoms 6 months after treatment.

“We emphasize that these results do not suggest that mindfulness-based therapy was not effective in treating grief-focused CBT, but rather that grief-focused CBT was relatively more effective in reducing prolonged grief disorder, depression, and grief-related cognitions than mindfulness-based cognitive therapy,” investigators, led by Richard Bryant, PhD, of the University of New South Wales, Sydney, Australia, wrote.

The findings were published online in JAMA Psychiatry.

Barrier to Treatment

Prolonged grief disorder can affect up to 10% of bereaved individuals and is associated with increased suicide risk, cancer, immunological dysfunction, cardiac events, and functional impairment.

One barrier to treatment for individuals with prolonged grief disorder is that the treatment process can be emotionally painful. Between 15% and 25% of patients with prolonged grief offered grief-focused CBT decline to participate because they are reluctant to focus on painful emotions surrounding the death of their loved one.

To compare grief-focused CBT with mindfulness-based CT, another psychotherapeutic treatment, investigators recruited 100 adults aged 18-70 years between 2012 and 2022.

Participants who met the criteria for prolonged grief disorder were randomized on a 1:1 basis to receive either grief-focused CBT (n = 50) or CT (n = 50). All assessors were blinded to the treatment condition.

Therapy in both groups included 11 weekly 90-minute individual sessions.

Participants were assessed posttreatment at the 6-month mark for prolonged grief disorder symptom severity with the Prolonged Grief (PG)-13 Scale. They were also assessed for symptoms of depression, anxiety, and self-reported quality of life.

Grief-focused CBT entailed education on prolonged grief disorder, monitoring of daily thoughts, revisiting the death memory for several sessions, reframing maladaptive grief-related thoughts, writing a letter to the deceased loved one, relapse prevention strategies, and goal setting.

Mindfulness-based CT was adapted to problematic grief and began with psychoeducation about prolonged grief disorder. The additional sessions entailed mindfulness-orienting exercises, meditation, body scans, and how mindfulness practices can be used to tolerate aversive emotions and thoughts or to manage grief reactions.

Participants were assessed at the end of their treatment and had a mean age of 47 years, and 87% were female. The majority (71%) were White, and 21% were African, Indigenous Australian, and Pacific Islander.

While participants in both groups had similar outcomes posttreatment, at the 6-month follow-up, grief-focused CBT led to more significant reductions in scores on the PG-13 scale compared with mindfulness-based CT (mean difference, 7.1 points; 95% CI, 1.6-12.5; P = .01) with a large between-group effect size (0.8; 95% CI, 0.2-1.3).

PG-13 scores range from 11 to 55, with higher scores indicating greater prolonged grief disorder severity.

Of note, both treatment groups had a significant reduction in prolonged grief disorder symptoms (mean difference, 11.3; 95% CI, 8.6-14.1; P < .001), with a large effect size (1.2; 95% CI, 0.9-1.5).

Grief-focused CBT also led to greater reductions in depression at 6 months as measured by the Beck Depression Inventory (mean difference, 6.6; 95% CI, 0.5-12.9; P = .04). Investigators noted that this finding was unexpected and “suggests that the greater reduction of depression in participants receiving grief-focused cognitive behavior therapy may be attributed to the superior reductions in prolonged grief disorder severity, thereby leading to downstream decreases in depression.”

The investigators noted several study limitations. Most participants were White, which limits the generalizability of the results to other races and ethnicities. Therapists were not blinded to treatment conditions, and investigators did not monitor participants’ therapeutic exercises that were to be practiced posttreatment until the 6-month mark.

The study was funded by the National Health and Medical Research Council. Dr. Bryant served on the ICD Eleventh Revision Working Group on the Classification of Stress-Related Disorders. No other disclosures were reported.

It’s becoming clear that the adolescent brain is particularly vulnerable to cannabis, especially today’s higher-potency products, which put teens at risk for impaired brain development; mental health issues, including psychosis; and cannabis-use disorder (CUD). 

That was the message delivered by Yasmin Hurd, PhD, director of the Addiction Institute at Mount Sinai in New York, during a press briefing at the American Psychiatric Association (APA) 2024 annual meeting. 

“We’re actually in historic times in that we now have highly concentrated, highly potent cannabis products that are administered in various routes,” Dr. Hurd told reporters. 

Tetrahydrocannabinol (THC) concentrations in cannabis products have increased over the years, from around 2%-4% to 15%-24% now, Dr. Hurd noted.

The impact of high-potency cannabis products and increased risk for CUD and mental health problems, particularly in adolescents, “must be taken seriously, especially in light of the current mental health crisis,” Dr. Hurd and colleagues wrote in a commentary on the developmental trajectory of CUD published simultaneously in the American Journal of Psychiatry. 
 

Dramatic Increase in Teen Cannabis Use

A recent study from Oregon Health & Science University showed that adolescent cannabis abuse in the United States has increased dramatically, by about 245%, since 2000. 

“Drug abuse is often driven by what is in front of you,” Nora Volkow, MD, director of the National Institute on Drug Abuse, noted in an interview. 

“Right now, cannabis is widely available. So, guess what? Cannabis becomes the drug that people take. Nicotine is much harder to get. It is regulated to a much greater extent than cannabis, so fewer teenagers are consuming nicotine than are consuming cannabis,” Dr. Volkow said. 

Cannabis exposure during neurodevelopment has the potential to alter the endocannabinoid system, which in turn, can affect the development of neural pathways that mediate reward; emotional regulation; and multiple cognitive domains including executive functioning and decision-making, learning, abstraction, and attention — all processes central to substance use disorder and other psychiatric disorders, Dr. Hurd said at the briefing.

Dr. Volkow said that cannabis use in adolescence and young adulthood is “very concerning because that’s also the age of risk for psychosis, particularly schizophrenia, with one study showing that use of cannabis in high doses can trigger psychotic episodes, particularly among young males.”

Dr. Hurd noted that not all young people who use cannabis develop CUD, “but a significant number do,” and large-scale studies have consistently reported two main factors associated with CUD risk.

The first is age, both for the onset and frequency of use at younger age. Those who start using cannabis before age 16 years are at the highest risk for CUD. The risk for CUD also increases significantly among youth who use cannabis at least weekly, with the highest prevalence among youth who use cannabis daily. One large study linked increased frequency of use with up to a 17-fold increased risk for CUD.

The second factor consistently associated with the risk for CUD is biologic sex, with CUD rates typically higher in male individuals.
 

Treatment Challenges

For young people who develop CUD, access to and uptake of treatment can be challenging.

“Given that the increased potency of cannabis and cannabinoid products is expected to increase CUD risk, it is disturbing that less than 10% of youth who meet the criteria for a substance use disorder, including CUD, receive treatment,” Dr. Hurd and colleagues point out in their commentary. 

Another challenge is that treatment strategies for CUD are currently limited and consist mainly of motivational enhancement and cognitive-behavioral therapies. 

“Clearly new treatment strategies are needed to address the mounting challenge of CUD risk in teens and young adults,” Dr. Hurd and colleagues wrote. 

Summing up, Dr. Hurd told reporters, “We now know that most psychiatric disorders have a developmental origin, and the adolescent time period is a critical window for cannabis use disorder risk.”

Yet, on a positive note, the “plasticity of the developing brain that makes it vulnerable to cannabis use disorder and psychiatric comorbidities also provides an opportunity for prevention and early intervention to change that trajectory,” Dr. Hurd said. 

The changing legal landscape of cannabis — the US Drug Enforcement Agency is moving forward with plans to move marijuana from a Schedule I to a Schedule III controlled substance under the Controlled Substance Act — makes addressing these risks all the timelier. 

“As states vie to leverage tax dollars from the growing cannabis industry, a significant portion of such funds must be used for early intervention/prevention strategies to reduce the impact of cannabis on the developing brain,” Dr. Hurd and colleagues wrote.

It’s becoming clear that the adolescent brain is particularly vulnerable to cannabis, especially today’s higher-potency products, which put teens at risk for impaired brain development; mental health issues, including psychosis; and cannabis-use disorder (CUD). 

That was the message delivered by Yasmin Hurd, PhD, director of the Addiction Institute at Mount Sinai in New York, during a press briefing at the American Psychiatric Association (APA) 2024 annual meeting. 

“We’re actually in historic times in that we now have highly concentrated, highly potent cannabis products that are administered in various routes,” Dr. Hurd told reporters. 

Tetrahydrocannabinol (THC) concentrations in cannabis products have increased over the years, from around 2%-4% to 15%-24% now, Dr. Hurd noted.

The impact of high-potency cannabis products and increased risk for CUD and mental health problems, particularly in adolescents, “must be taken seriously, especially in light of the current mental health crisis,” Dr. Hurd and colleagues wrote in a commentary on the developmental trajectory of CUD published simultaneously in the American Journal of Psychiatry. 
 

Dramatic Increase in Teen Cannabis Use

A recent study from Oregon Health & Science University showed that adolescent cannabis abuse in the United States has increased dramatically, by about 245%, since 2000. 

“Drug abuse is often driven by what is in front of you,” Nora Volkow, MD, director of the National Institute on Drug Abuse, noted in an interview. 

“Right now, cannabis is widely available. So, guess what? Cannabis becomes the drug that people take. Nicotine is much harder to get. It is regulated to a much greater extent than cannabis, so fewer teenagers are consuming nicotine than are consuming cannabis,” Dr. Volkow said.

TORONTO — An ambitious effort at a busy pediatrics clinic to improve follow-up in children and adolescents with a positive depression screen improved this quality metric, and it produced a fundamental change in approach.

“It was a big culture shift,” reported Landon B. Krantz, MD, a clinical fellow in the Division of General and Community Pediatrics at Cincinnati Children’s Hospital in Ohio. From a baseline position of screening, risk identification, and then referral, “we are now taking ownership of the process.”

Based on the substantial risk posed by significant levels of depression, guidelines recommend follow-up for any patient 12 years or older who has a positive screen, according to Dr. Krantz. At his center, they found only 19% had a documented follow-up within 30 days, even though timely intervention is important.

“Nearly half of suicide events in adolescents occur within 30 days after a positive PHQ-9 [9-question Patient Health Questionnaire] is completed,” said Dr. Krantz when presenting his data at the Pediatric Academic Societies annual meeting.

The issue has gained more urgency because of the substantial increase over the past several years in children presenting with depression and suicidal thoughts, according to Dr. Krantz. He said many are characterizing the upsurge as a mental health crisis in the pediatric age group.
 

Improving Follow-Up

The goal of the initiative launched at six primary care practices in Cincinnati was to increase the proportion of children with a positive screen for depression who have a follow-up within 30 days. The goal at the outset was to increase the proportion to 35%.

“We know that a lot of children would receive follow-up at centers outside of our system,” said Dr. Krantz, explaining why the goal was relatively modest. Based on the likelihood that many follow-up visits would not be captured, he expected the final data would represent an underestimate.

Depression at baseline was defined as a score of 10 or higher on the PHQ-9 or any positive answer to item 9 on this screening tool, which asks specifically about thoughts of self-harm.

To be counted, follow-up had to be a documented encounter, whether by phone call, in-person visit, or telehealth visit.

“We needed patients to be checked. We did not count a prescription refill as a true follow-up,” Dr. Krantz specified.

There were numerous strategies implemented to improve follow-up, not least of which was an educational program to reinforce the importance and value of follow-up that was disseminated to clinicians in all of the participating clinics. Medical assistants were instructed to schedule a follow-up appointment for all patients who tested positive before they left the office. A target of 3 weeks was a strategy of overcorrection when so many patients were missing the initial 30-day window by just a few days.

The approach also involved an enhanced collaboration with psychologists to which patients were referred. Asking for expedited appointments when appropriate ensured that those at highest risk were prioritized, although Dr. Krantz said that this step was planned carefully to avoid overwhelming the mental health team.

“We monitored this and made sure it was not increasing the burden for psychologists from a capacity standpoint,” he said.

Other steps, like a depression action plan, which Dr. Krantz compared to an asthma action plan, were also implemented to reduce the risk of losing symptomatic patients before the chance for an effective treatment.

When compared with the 19% 30-day follow-up rate in the preintervention sample of 589 children, the 43.8% 30-day follow-up rate achieved in the 764 patients identified after implementation beat the original goal.

The improvement in follow-up was relatively consistent across all six clinics, which Dr. Krantz believes reflected a broad and shared change in a sense of responsibility for confirming that symptoms of depression were being addressed. Patients were still referred for psychological help, but referral was no longer considered enough.

“Children with mental health issues are still our patients in primary care,” said Dr. Krantz, who considers this an important change in orientation.

While the goal was to schedule patients for a follow-up at the time of a positive depression screen, Dr. Krantz described one important accommodation.

“The screen for depression was being performed in most cases during well visits, so patients and their families were not expecting to be discussing this issue,” he said. The diagnosis might be a particular surprise to parents who were not aware of any symptoms. In this case, Dr. Krantz said patients and families were given time to process the information and were contacted after a week to discuss further workup.

It is also notable that about one third of patients met the criteria for depression by answering positively to the PHQ-9 item on self-harm when they did not meet the 10 or more threshold depression score overall. In other words, these patients would have been missed without this criterion.

In the participating Cincinnati pediatric clinics, about 12%-13% of adolescents met the criteria for depression, which Dr. Krantz said is consistent with reports in the literature. He said the range is about 6%-24%.

Although outcomes were not tracked, there is evidence that early intervention for depression yields better outcomes than delayed intervention, according to Dr. Krantz. Based on approximately 600 positive screens for depression per year at his pediatric clinics, he estimated that his data predict at least 25% more patients will receive timely follow-up.
 

Seeking Solutions to a Growing Problem

There are several studies documenting the growing problem of adolescent depression and suicide and, for this reason, the topic is attracting a lot of attention, according to Corinna Rea, MD, MPH, a pediatrician working in the primary care center at Boston Children’s Hospital in Massachusetts.

Dr. Rea was not involved with the study, but when asked to comment, she said: “The results of this study were encouraging because we know that getting patients to care quickly is probably important.” She also agreed that referring patients with depression for care might not be enough, noting that a lot of patients do not follow up on recommendations to pursue a consultation or treatment.

“I am now involved in a project with the American Academy of Pediatrics to address this issue,” Dr. Rae said. She thinks that more work in this area is needed and agreed with Dr. Krantz that pediatricians should verify that children with depression are getting help even when other specialists are providing the treatment.

Dr. Krantz and Dr. Rae report no potential conflicts of interest.

Hospitalized patients with dementia and dysphagia are often prescribed a “dysphagia diet,” made up of texture-modified foods and thickened liquids in an effort to reduce the risk for aspiration or other problems. However, a new study calls this widespread and long-held practice into question.

Investigators found no evidence that the use of thickened liquids reduced mortality or respiratory complications, such as pneumonia, aspiration, or choking, compared with thin-liquid diets in patients with Alzheimer’s disease and related dementias (ADRD) and dysphagia. Patients receiving thick liquids were less likely to be intubated, but they were actually more likely to have respiratory complications.

“When hospitalized patients with Alzheimer’s disease and related dementias are found to have dysphagia, our go-to solution is to use a thick liquid diet,” senior author Liron Sinvani, MD, with the Feinstein Institutes for Medical Research, Manhasset, New York, said in a news release.

“However, there is no concrete evidence that thick liquids improve health outcomes, and we also know that thick liquids can lead to decreased palatability, poor oral intake, dehydration, malnutrition, and worse quality of life,” added Dr. Sinvani, director of the geriatric hospitalist service at Northwell Health in New York.

The study was published online in JAMA Internal Medicine.
 

Challenging a Go-To Solution

The researchers compared outcomes in a propensity score-matched cohort of patients with ADRD and dysphagia (mean age, 86 years; 54% women) receiving mostly thick liquids versus thin liquids during their hospitalization. There were 4458 patients in each group.

They found no significant difference in hospital mortality between the thick liquids and thin liquids groups (hazard ratio [HR], 0.92; P = .46).

Patients receiving thick liquids were less likely to require intubation (odds ratio [OR], 0.66; 95% CI, 0.54-0.80) but were more likely to develop respiratory complications (OR, 1.73; 95% CI, 1.56-1.91).

The two groups did not differ significantly in terms of risk for dehydration, hospital length of stay, or rate of 30-day readmission.

“This cohort study emphasizes the need for prospective studies that evaluate whether thick liquids are associated with improved clinical outcomes in hospitalized patients with ADRD and dysphagia,” the authors wrote.

Because few patients received a Modified Barium Swallow Study at baseline, researchers were unable to confirm the presence of dysphagia or account for dysphagia severity and impairment. It’s possible that patients in the thick liquid group had more severe dysphagia than those in the thin liquid group.

Another limitation is that the type of dementia and severity were not characterized. Also, the study could not account for factors like oral hygiene, immune status, and diet adherence that could impact risks like aspiration pneumonia.
 

Theoretical Benefit, No Evidence

In an invited commentary on the study, Eric Widera, MD, with University of California San Francisco, noted that medicine is “littered with interventions that have become the standard of practice based on theoretical benefits without clinical evidence”.

One example is percutaneous endoscopic gastrostomy tubes for individuals with dysphagia and dementia.

“For decades, these tubes were regularly used in individuals with dementia on the assumption that bypassing the oropharyngeal route would decrease rates of aspiration and, therefore, decrease adverse outcomes like pressure ulcers, malnutrition, pneumonia, and death. However, similar to what we see with thickened liquids, evidence slowly built that this standard of practice was not evidence-based practice,” Dr. Widera wrote.

When thinking about thick liquid diets, Dr. Widera encouraged clinicians to “acknowledge the limitations of the evidence both for and against thickened-liquid diets.”

He also encouraged clinicians to “put yourself in the shoes of the patients who will be asked to adhere to this modified diet. For 12 hours, drink your tea, coffee, wine, and water as thickened liquids,” Dr. Widera suggested. “The goal is not to convince yourself never to prescribe thickened liquids, but rather to be mindful of how a thickened liquid diet affects patients’ liquid and food intake, how it changes the mouthfeel and taste of different drinks, and how it affects patients’ quality of life.”

Clinicians also should “proactively engage speech-language pathologists, but do not ask them if it is safe for a patient with dementia to eat or drink normally. Instead, ask what we can do to meet the patient’s goals and maintain quality of life given the current evidence base,” Dr. Widera wrote.

“For some, when the patient’s goals are focused on comfort, this may lead to a recommendation for thickened liquids if their use may resolve significant coughing distress after drinking thin liquids. Alternatively, even when the patient’s goals are focused on prolonging life, the risks of thickened liquids, including dehydration and decreased food and fluid intake, as well as the thin evidence for mortality improvement, will argue against their use,” Dr. Widera added.

Funding for the study was provided by grants from the National Institute on Aging and by the William S. Middleton Veteran Affairs Hospital, Madison, Wisconsin. Dr. Sinvani and Dr. Widera declared no relevant conflicts of interest.

Hospitalized patients with dementia and dysphagia are often prescribed a “dysphagia diet,” made up of texture-modified foods and thickened liquids in an effort to reduce the risk for aspiration or other problems. However, a new study calls this widespread and long-held practice into question.

Investigators found no evidence that the use of thickened liquids reduced mortality or respiratory complications, such as pneumonia, aspiration, or choking, compared with thin-liquid diets in patients with Alzheimer’s disease and related dementias (ADRD) and dysphagia. Patients receiving thick liquids were less likely to be intubated, but they were actually more likely to have respiratory complications.

“When hospitalized patients with Alzheimer’s disease and related dementias are found to have dysphagia, our go-to solution is to use a thick liquid diet,” senior author Liron Sinvani, MD, with the Feinstein Institutes for Medical Research, Manhasset, New York, said in a news release.

“However, there is no concrete evidence that thick liquids improve health outcomes, and we also know that thick liquids can lead to decreased palatability, poor oral intake, dehydration, malnutrition, and worse quality of life,” added Dr. Sinvani, director of the geriatric hospitalist service at Northwell Health in New York.

The study was published online in JAMA Internal Medicine.
 

Challenging a Go-To Solution

The researchers compared outcomes in a propensity score-matched cohort of patients with ADRD and dysphagia (mean age, 86 years; 54% women) receiving mostly thick liquids versus thin liquids during their hospitalization. There were 4458 patients in each group.

They found no significant difference in hospital mortality between the thick liquids and thin liquids groups (hazard ratio [HR], 0.92; P = .46).

Patients receiving thick liquids were less likely to require intubation (odds ratio [OR], 0.66; 95% CI, 0.54-0.80) but were more likely to develop respiratory complications (OR, 1.73; 95% CI, 1.56-1.91).

The two groups did not differ significantly in terms of risk for dehydration, hospital length of stay, or rate of 30-day readmission.

“This cohort study emphasizes the need for prospective studies that evaluate whether thick liquids are associated with improved clinical outcomes in hospitalized patients with ADRD and dysphagia,” the authors wrote.

Because few patients received a Modified Barium Swallow Study at baseline, researchers were unable to confirm the presence of dysphagia or account for dysphagia severity and impairment. It’s possible that patients in the thick liquid group had more severe dysphagia than those in the thin liquid group.

Another limitation is that the type of dementia and severity were not characterized. Also, the study could not account for factors like oral hygiene, immune status, and diet adherence that could impact risks like aspiration pneumonia.
 

Theoretical Benefit, No Evidence

In an invited commentary on the study, Eric Widera, MD, with University of California San Francisco, noted that medicine is “littered with interventions that have become the standard of practice based on theoretical benefits without clinical evidence”.

One example is percutaneous endoscopic gastrostomy tubes for individuals with dysphagia and dementia.

“For decades, these tubes were regularly used in individuals with dementia on the assumption that bypassing the oropharyngeal route would decrease rates of aspiration and, therefore, decrease adverse outcomes like pressure ulcers, malnutrition, pneumonia, and death. However, similar to what we see with thickened liquids, evidence slowly built that this standard of practice was not evidence-based practice,” Dr. Widera wrote.

When thinking about thick liquid diets, Dr. Widera encouraged clinicians to “acknowledge the limitations of the evidence both for and against thickened-liquid diets.”

He also encouraged clinicians to “put yourself in the shoes of the patients who will be asked to adhere to this modified diet. For 12 hours, drink your tea, coffee, wine, and water as thickened liquids,” Dr. Widera suggested. “The goal is not to convince yourself never to prescribe thickened liquids, but rather to be mindful of how a thickened liquid diet affects patients’ liquid and food intake, how it changes the mouthfeel and taste of different drinks, and how it affects patients’ quality of life.”
