A new light therapy device could be a game-changer for millions at risk of vision loss. The Food and Drug Administration (FDA) has approved a first-of-its-kind treatment for dry age-related macular degeneration (AMD), a leading cause of blindness in adults over 55.

Developed by LumiThera, the device showed promising results in a clinical trial, marking it as the first effective therapy for AMD. Approved under the FDA’s “De Novo” process, the treatment offers hope where no similar options existed.

The LumiThera study, done at 10 retinal centers in the United States, assessed the safety and effectiveness of the system on the eyes of 100 people over a 24-month period. The data collected during the trial was then analyzed over a 13-month period. 

The trial found that LumiThera’s Valeda Light Delivery System significantly reduced the risk of vision loss and the start of geographic atrophy in dry AMD. More than 58% of the people studied reported improvements in their sight after the therapy. 

Geographic atrophy is a treacherous hallmark of late-stage dry AMD, in which cells in the center of the eye’s retina — called the macula — die, which can cause severe vision loss in advanced forms of the disease.

LumiThera’s system is the first treatment authorized by the FDA for vision loss from dry AMD. AMD is a leading cause of irreversible blindness or vision loss in people over 60. Around 20 million people in the United States have AMD, with dry AMD accounting for 90% of diagnosed cases. It’s considered “dry” because it doesn’t involve the growth of abnormal blood vessels, the way the “wet” form of AMD does.

The percentage of people with dry AMD who lose their vision depends on how severe the disease is and whether it becomes the wet form, which is more severe than the dry form. The wet form is marked by blood vessels leaking into the macula and the loss of central vision. Around 10%-15% of dry AMD cases become the wet form. 

During a presentation in 2024 at a meeting of the American Society of Retina Specialists, Eleonora Lad, MD, PhD, vice chair of ophthalmology clinical research at Duke University Medical Center, said the treatment — known as “photobiomodulation” (PBM) — is the first to deliver “meaningful effects” in dry AMD.

But how does PBM work, and what specifically improved in the eyes of the people in the study to help combat the disease?

 

Specific Wavelengths of Light Improve Cellular Function

Until now, taking nutritional supplements (vitamin C, vitamin E, lutein, zeaxanthin, zinc, and copper) was among the most common ways of treating dry AMD. The efficacy with this combo of nutritional supplements was established by the Age-Related Eye Disease Study 2 (AREDS2). The supplements help lower the risk of advanced dry AMD and wet AMD. 

There are also recently approved eye injections for dry AMD, such as the drugs Syfovre and Izervay, to treat later stages of the disease. But while both Syfovre and Izervay can slow the progression of geographic atrophy by about 14%-20%, patients receiving either drug have a higher risk of getting wet AMD, and the treatments are invasive. The drugs must be injected directly into the middle of the eye around once per month. 

PBM works by delivering specific wavelengths of light to the retina that help cells in retinal tissue, increasing energy production by mitochondria in eye cells, decreasing inflammation, and increasing nutrients and oxygen for cells. This improves cell survival in dry AMD and could slow the disease or stop it from reaching later stages.

Several eye disorders may be partly caused by oxidative stress and impaired mitochondrial function. The wavelength of light used in PBM stimulates an enzyme in eye cells that is key to healthy cellular function and vision. 

Research has shown that PBM prevents oxidative stress, which damages retinal pigment epithelial cells and could lead to AMD.

 

More Study Is Needed

PBM has been around for decades and has been promoted as a treatment for dementia, smoking cessation, spinal cord injury, and wound healing, along with AMD. 

“Google photobiomodulation or light therapy, and you’ll find it’s supposed to fix everything ... people try to sell it for everything, and that’s because they own the equipment, and they’re looking to recoup their costs,” said Jason M. Miller, MD, PhD, a retinal disease specialist at the Kellogg Eye Center at the University of Michigan School of Medicine, Ann Arbor.

He said more rigorous and larger trials are need before PBM therapy should gain wider FDA approval.

The FDA’s De Novo approval process is for medical devices that have designs that are unlike others already on the market. To get full approval from the FDA, a new drug or device must be assessed in a clinical trial that involves more people than the 100 or so that LumiThera used in its trial. For example, phase 3 trials for drugs usually involve 1,000-3,000 people.

Syfovre’s phase 3 clinical trials involved 1,258 patients. 

Research has shown that perceptions of visual acuity could also color the study results in a way that distorts the actual effectiveness of treatment, the way the placebo effect works. Some people in studies may simply think their vision is improving because they know they’re getting treatment. 

In a 2022 study, researchers showed that people in a trial who were given a placebo with the expectation the treatment would work reported a more favorable response to treatment than those who received a “nocebo” they were told wouldn’t work. 

The sensitivity of response to the placebo/nocebo treatments were shown to rely on the expectations caused by the experiment, and the study’s findings provided evidence that “both ocular accommodation and stereoacuity can be influenced by manipulating expectations and belief about the efficacy of an inert treatment.”

“The placebo effect in medicine is just rampant. It accounts for, in some trials, 30%-40% of an effect. ... I would have a hard time buying this device right now. I don’t want to say it’s ineffective, I just want more data,” said Miller.

TOPLINE:

Patients with rectal cancer managed by watch and wait and subsequent local regrowth have a higher risk for distant metastases than those undergoing immediate surgery. The new study highlights the importance of timely surgical intervention to improve distant metastases–free survival rates.

METHODOLOGY:

• Organ preservation has become an attractive alternative to surgery for patients with rectal cancer who achieve a clinical complete response after neoadjuvant therapy, with the risk for local regrowth after initial clinical complete response being around 25%-30%.
• The new study aimed to compare the risk for distant metastases between patients with local regrowth after watch and wait and patients with near-complete pathologic response managed by total mesorectal excision.
• A total of 508 patients with local regrowth were included from the International Watch & Wait Database, and 893 patients with near-complete pathologic response were included from the Spanish Rectal Cancer Project.
• The primary endpoint was distant metastases–free survival at 3 years from the decision to watch and wait or total mesorectal excision, and the secondary endpoints included possible risk factors associated with distant metastases.

TAKEAWAY:

• Patients with local regrowth had a significantly higher rate of distant metastases (rate, 22.8% vs 10.2%; P ≤.001) than those with near-complete pathologic response managed by total mesorectal excision.
• Distant metastases–free survival at 3 years was significantly worse for patients with local regrowth (rate, 75% vs 87%; P < .001).
• Independent risk factors for distant metastases included local regrowth (vs total mesorectal excision at reassessment; P = .001), ypT3-4 status (P = .016), and ypN+ status (P = .001) at the time of surgery.
• Patients with local regrowth had worse distant metastases–free survival across all pathologic stages than those managed by total mesorectal excision.

IN PRACTICE:

“Patients with local regrowth appear to have a higher risk for subsequent distant metastases development than patients with near-complete pathologic response managed by total mesorectal excision at restaging irrespective of final pathology,” the authors wrote.

SOURCE:

This study was led by Laura M. Fernandez, MD, of the Champalimaud Foundation in Lisbon, Portugal. It was published online in Journal of Clinical Oncology.

LIMITATIONS:

This study’s limitations included the heterogeneity in defining clinical complete response and the decision to watch and wait across different institutions. The majority of patients did not receive total neoadjuvant therapy regimens, which may have affected the generalizability of the findings. The study had a considerable amount of follow-up losses, which could have introduced bias.

DISCLOSURES:

This study was supported by the European Society of Surgical Oncology, the Champalimaud Foundation, the Bas Mulder Award, the Alpe d’HuZes Foundation, the Dutch Cancer Society, the European Research Council Advanced Grant, and the National Institute of Health and Research Manchester Biomedical Research Centre.

TOPLINE:

Donepezil was associated with improved verbal memory and enhanced recall and processing speed, compared with placebo, in patients with severe traumatic brain injury (TBI), with a favorable safety profile despite mild to moderate gastrointestinal side effects.

METHODOLOGY:

• A four-site, randomized, parallel-group, double-blind, placebo-controlled, 10-week clinical trial (MEMRI-TBI-D) was conducted between 2013 and 2019 to evaluate the efficacy of donepezil for verbal memory impairments following severe TBI.
• 75 adults (75% men; mean age, 37 years) with complicated mild, moderate, or severe nonpenetrating TBI at least 6 months prior to study participation were included and randomly assigned to receive donepezil (n = 37) or placebo (n = 38).
• Participants received 5 mg donepezil daily or matching placebo for 2 weeks, then donepezil at 10 mg daily or matching placebo for 8 weeks; treatment was discontinued at 10 weeks, with an additional 4-week observation period.
• Verbal memory was assessed using the Hopkins Verbal Learning Test–Revised (HVLT-R). The primary outcome measure was verbal learning, evaluated through the HVLT-R total recall (ie, Total Trials 1-3) score.

TAKEAWAY:

• Compared with placebo, donepezil was associated with significantly greater improvements in verbal learning in both modified intent-to-treat and per-protocol analyses (P = .034 and .036, respectively).
• Treatment-responder rates were significantly higher in the donepezil group than in the placebo group (42 vs 18%; P = .03), with donepezil responders showing significant improvements in delayed recall and processing speed.
• Although there were no serious adverse events in either group, treatment-emergent adverse events were significantly more common in the donepezil group vs placebo (46% vs 8%; P < .001). No serious adverse events occurred in either group.
• Diarrhea and nausea were significantly more common in the donepezil group than in the placebo group (Fisher’s exact test: diarrhea, P = .03; nausea, P = .01).

IN PRACTICE:

“This study demonstrates the efficacy of donepezil on severe, persistent verbal memory impairments after predominantly severe TBI, with significant benefit for a subset of persons with such injuries, as well as a relatively favorable safety and tolerability profile,” the investigators wrote.

SOURCE:

The study was led by David B. Arciniegas, MD, University of Colorado School of Medicine, Aurora. It was published online in The Journal of Neuropsychiatry and Clinical Neurosciences.

LIMITATIONS:

The study included a relatively small sample with predominantly severe TBI requiring hospitalization and inpatient rehabilitation. The sample characteristics limit the generalizability of the findings to persons with other severities of TBI, other types of memory impairments, or more complex neuropsychiatric presentations. The study population had an average of 14 years of education, making generalizability to individuals with lower education levels uncertain. Additionally, while measures of information processing speed and immediate auditory attention were included, specific measures of sustained or selective attention were not, making it difficult to rule out improvements in higher-level attention as potential contributors to the observed verbal memory performance improvements.

DISCLOSURES:

The study was funded by the National Institute on Disability, Independent Living, and Rehabilitation Research, with in-kind support from TIRR Memorial Hermann. Four authors disclosed various financial and professional affiliations, including advisory roles with pharmaceutical and diagnostic companies, support from institutional awards, and involvement in programs funded by external organizations. One author served as the editor of The Journal of Neuropsychiatry and Clinical Neurosciences, with an independent editor overseeing the review and publication process for this article.

TOPLINE:

Donepezil was associated with improved verbal memory and enhanced recall and processing speed, compared with placebo, in patients with severe traumatic brain injury (TBI), with a favorable safety profile despite mild to moderate gastrointestinal side effects.

METHODOLOGY:

• A four-site, randomized, parallel-group, double-blind, placebo-controlled, 10-week clinical trial (MEMRI-TBI-D) was conducted between 2013 and 2019 to evaluate the efficacy of donepezil for verbal memory impairments following severe TBI.
• 75 adults (75% men; mean age, 37 years) with complicated mild, moderate, or severe nonpenetrating TBI at least 6 months prior to study participation were included and randomly assigned to receive donepezil (n = 37) or placebo (n = 38).
• Participants received 5 mg donepezil daily or matching placebo for 2 weeks, then donepezil at 10 mg daily or matching placebo for 8 weeks; treatment was discontinued at 10 weeks, with an additional 4-week observation period.
• Verbal memory was assessed using the Hopkins Verbal Learning Test–Revised (HVLT-R). The primary outcome measure was verbal learning, evaluated through the HVLT-R total recall (ie, Total Trials 1-3) score.

TAKEAWAY:

• Compared with placebo, donepezil was associated with significantly greater improvements in verbal learning in both modified intent-to-treat and per-protocol analyses (P = .034 and .036, respectively).
• Treatment-responder rates were significantly higher in the donepezil group than in the placebo group (42 vs 18%; P = .03), with donepezil responders showing significant improvements in delayed recall and processing speed.
• Although there were no serious adverse events in either group, treatment-emergent adverse events were significantly more common in the donepezil group vs placebo (46% vs 8%; P < .001). No serious adverse events occurred in either group.
• Diarrhea and nausea were significantly more common in the donepezil group than in the placebo group (Fisher’s exact test: diarrhea, P = .03; nausea, P = .01).

IN PRACTICE:

“This study demonstrates the efficacy of donepezil on severe, persistent verbal memory impairments after predominantly severe TBI, with significant benefit for a subset of persons with such injuries, as well as a relatively favorable safety and tolerability profile,” the investigators wrote.

SOURCE:

The study was led by David B. Arciniegas, MD, University of Colorado School of Medicine, Aurora. It was published online in The Journal of Neuropsychiatry and Clinical Neurosciences.

LIMITATIONS:

The study included a relatively small sample with predominantly severe TBI requiring hospitalization and inpatient rehabilitation. The sample characteristics limit the generalizability of the findings to persons with other severities of TBI, other types of memory impairments, or more complex neuropsychiatric presentations. The study population had an average of 14 years of education, making generalizability to individuals with lower education levels uncertain. Additionally, while measures of information processing speed and immediate auditory attention were included, specific measures of sustained or selective attention were not, making it difficult to rule out improvements in higher-level attention as potential contributors to the observed verbal memory performance improvements.

Results from the British COLO-DETECT trial add to the growing body of evidence supporting the use of artificial intelligence (AI)–aided colonoscopy to increase premalignant colorectal polyp detection in routine colonoscopy practice.

Colin J. Rees, a professor of gastroenterology in the Faculty of Medical Sciences at Newcastle University in Newcastle upon Tyne, England, and colleagues compared the real-world clinical effectiveness of computer-aided detection (CADe)–assisted colonoscopy using an “intelligent” module with that of standard colonoscopy in a study in The Lancet Gastroenterology & Hepatology.

They found the GI Genius Intelligent Endoscopy Module (Medtronic) increased the mean number of adenomas detected per procedure and the adenoma detection rate, especially for small, flat (type 0-IIa) polyps, and sessile serrated lesions, which are more likely to be missed.

“Missed sessile serrated lesions disproportionately increase the risk of post-colonoscopy colorectal cancer, thus the adoption of GI Genius into routine colonoscopy practice could not only increase polyp detection but also reduce the incidence of post-colonoscopy colorectal cancer,” the investigators wrote.

“AI is going to have a major impact upon most aspects of healthcare. Some areas of medical practice are now well established, and some are still in evolution,” Rees, who is also president of the British Society of Gastroenterology, said in an interview. “Within gastroenterology, the role of AI in endoscopic diagnostics is also evolving. The COLO-DETECT trial demonstrates that AI increases detection of lesions, and work is ongoing to see how AI might help with characterization and other elements of endoscopic practice.”

 

Study Details

The multicenter, open-label, parallel-arm, pragmatic randomized controlled trial was conducted at 12 National Health Service hospitals in England. The study cohort consisted of adults ≥ 18 years undergoing colorectal cancer (CRC) screening or colonoscopy for gastrointestinal symptom surveillance owing to personal or family history.

Recruiting staff, participants, and colonoscopists were unmasked to allocation, whereas histopathologists, cochief investigators, and trial statisticians were masked.

CADe-assisted colonoscopy consisted of standard colonoscopy plus the GI Genius module active for at least the entire inspection phase of colonoscope withdrawal.

The primary outcome was mean adenomas per procedure (total number of adenomas detected divided by total number of procedures). The key secondary outcome was adenoma detection rate (proportion of colonoscopies with at least one adenoma).

From March 2021 to April 2023, the investigators recruited 2032 participants, 55.7% men, with a mean cohort age of 62.4 years and randomly assigned them to CADe-assisted colonoscopy (n = 1015) or to standard colonoscopy (n = 1017). Of these, 60.6% were undergoing screening and 39.4% had symptomatic indications.

Mean adenomas per procedure were 1.56 (SD, 2.82; n = 1001 participants with data) in the CADe-assisted group vs 1.21 (n = 1009) in the standard group, for an adjusted mean difference of 0.36 (95% CI, 0.14-0.57; adjusted incidence rate ratio, 1.30; 95% CI, 1.15-1.47; P < .0001).

Adenomas were detected in 555 (56.6%) of 980 participants in the CADe-assisted group vs 477 (48.4%) of 986 in the standard group, representing a proportion difference of 8.3% (95% CI, 3.9-12.7; adjusted odds ratio, 1.47; 95% CI, 1.21-1.78; P < .0001).

As to safety, adverse events were numerically comparable in both the intervention and control groups, with overall events 25 vs 19 and serious events 4 vs 6. On independent review, no adverse events in the CADe-assisted colonoscopy group were related to GI Genius.

 

Offering a US perspective on the study, Nabil M. Mansour, MD, an associate professor and director of the McNair General GI Clinic at Baylor College of Medicine in Houston, Texas, said GI Genius and other CADe systems represent a significant advance over standard colonoscopy for identifying premalignant polyps. “While the data have been mixed, most studies, particularly randomized controlled trials have shown significant improvements with CADe in detection both terms of in adenomas per colonoscopy and reductions in adenoma miss rate,” he said in an interview.

He added that the main utility of CADe is for asymptomatic patients undergoing average-risk screening and surveillance colonoscopy for CRC screening and prevention, as well as for those with positive stool-based screening tests, “though there is no downside to using it in symptomatic patients as well.” Though AI colonoscopy likely still stands at < 50% of endoscopy centers overall, and is used mainly at academic centers, his clinic has been using it for the past year.

The main question, Mansour cautioned, is whether increased detection of small polyps will actually reduce CRC incidence or mortality, and it will likely be several years before clear, concrete data can answer that.

“Most studies have shown the improvement in adenoma detection is mainly for diminutive polyps < 5 mm in diameter, but whether that will actually translate to substantive improvements in hard outcomes is as yet unknown,” he said. “But if gastroenterologists are interested in doing everything they can today to help improve detection rates and lower miss rates of premalignant polyps, serious consideration should be given to adopting the use of CADe in practice.”

This study was supported by Medtronic. Rees reported receiving grant funding from ARC Medical, Norgine, Medtronic, 3-D Matrix, and Olympus Medical, and has been an expert witness for ARC Medical. Other authors disclosed receiving research funding, honoraria, or travel expenses from Medtronic or other private companies. Mansour had no competing interests to declare.

TOPLINE:

In a multinational phase 3 trial, imipenem-cilastatin-relebactam demonstrated noninferiority to piperacillin-tazobactam in treating critically ill patients with hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP), with a comparable safety profile.

METHODOLOGY:

• This multinational phase 3 trial, conducted between September 2018 and July 2022, compared imipenem-cilastatin-relebactam with piperacillin-tazobactam for HABP and VABP to support its use across multiple countries.
• Overall, 270 patients with HABP or VABP (mean age, 57.6 years; 73.3% men) were randomly assigned to receive either intravenous imipenem-cilastatin-relebactam (500 mg/250 mg) or piperacillin-tazobactam (4000 mg/500 mg) every 6 hours over 30 minutes for 7-14 days.
• Both treatment groups included critically ill patients, with 54.5% and 55.1% of patients in the imipenem-cilastatin-relebactam and piperacillin-tazobactam groups, respectively, having an Acute Physiology and Chronic Health Evaluation II score ≥ 15.
• The primary outcome was the 28-day all-cause mortality; secondary outcomes included the rates of clinical and microbiological responses, as well as the incidence of adverse events.

TAKEAWAY:

• Imipenem-cilastatin-relebactam was noninferior to piperacillin-tazobactam in terms of 28-day all-cause mortality (adjusted difference, 5.2%; 95% CI, −1.5-12.4; P = .024 for noninferiority).
• At the end of treatment, the rates of a favorable clinical response were comparable between the imipenem-cilastatin-relebactam (71.6%) and piperacillin-tazobactam (68.4%) groups.
• After treatment, microbiological response rates were 48.8% in the imipenem-cilastatin-relebactam group, whereas the rates were 47.9% in the piperacillin-tazobactam group.
• The incidence of drug-related adverse events was similar across the treatment groups, with diarrhea, increased levels of alanine aminotransferase and aspartate aminotransferase, and abnormal hepatic function being the most common events.

IN PRACTICE:

“These results support the use of IMI/REL [imipenem-cilastatin-relebactam] in MDR [multidrug-resistant] infections globally, including to expand the range of available treatments for critically ill patients with HABP/VABP in China, and provide additional data to inform the World Health Organization’s MDR pathogen strategy,” the authors wrote.

TOPLINE:

Stem cell transplantation tames some refractory systemic juvenile idiopathic arthritis–related lung disease that does not respond to other treatment.

METHODOLOGY:

• Retrospective cohort study of 13 children with refractory systemic juvenile idiopathic arthritis–related lung disease (sJIA-LD) who had allogeneic hematopoietic stem cell transplantation (HSCT).
• Children whose median age was 9 years at transplantation underwent HSCT at nine hospitals in the United States and Europe between January 2018 and October 2022, with a median follow-up of 16 months.
• Outcomes included transplant-related complications, pulmonary outcomes (eg, oxygen dependence and chest CT findings), and overall outcomes (eg, complete response, partial response, and death).

TAKEAWAY:

• Five patients developed acute graft vs host disease of varying grades, but none experienced chronic disease.
• All nine surviving patients achieved a complete response at the last follow-up, with no sJIA characteristics or need for immunosuppressive therapy or supplemental oxygen.
• Four patients died from complications including cytomegalovirus pneumonitis (n = 2), intracranial hemorrhage (n = 1), and progressive sJIA-LD (n = 1).
• Of six patients who underwent posttransplant chest CT, three had improved lung health, two had stable lung disease, and one experienced worsening lung disease, ultimately resulting in death.

IN PRACTICE:

“Allogeneic HSCT should be considered for treatment-refractory sJIA-LD,” the authors wrote.

“Efforts are being pursued for earlier recognition of patients with sJIA-LD at risk of adverse reactions to biologics. Early detection should help to avoid repeated treatments that are less effective and possibly deleterious and consider therapeutic approaches (eg, anti–[interleukin]-18 or [interferon]-delta–targeted treatments) that might act as a bridge therapy to control disease activity before HSCT,” wrote the author of an accompanying editorial.

TOPLINE:

Stem cell transplantation tames some refractory systemic juvenile idiopathic arthritis–related lung disease that does not respond to other treatment.

METHODOLOGY:

• Retrospective cohort study of 13 children with refractory systemic juvenile idiopathic arthritis–related lung disease (sJIA-LD) who had allogeneic hematopoietic stem cell transplantation (HSCT).
• Children whose median age was 9 years at transplantation underwent HSCT at nine hospitals in the United States and Europe between January 2018 and October 2022, with a median follow-up of 16 months.
• Outcomes included transplant-related complications, pulmonary outcomes (eg, oxygen dependence and chest CT findings), and overall outcomes (eg, complete response, partial response, and death).

TAKEAWAY:

• Five patients developed acute graft vs host disease of varying grades, but none experienced chronic disease.
• All nine surviving patients achieved a complete response at the last follow-up, with no sJIA characteristics or need for immunosuppressive therapy or supplemental oxygen.
• Four patients died from complications including cytomegalovirus pneumonitis (n = 2), intracranial hemorrhage (n = 1), and progressive sJIA-LD (n = 1).
• Of six patients who underwent posttransplant chest CT, three had improved lung health, two had stable lung disease, and one experienced worsening lung disease, ultimately resulting in death.

IN PRACTICE:

“Allogeneic HSCT should be considered for treatment-refractory sJIA-LD,” the authors wrote.

“Efforts are being pursued for earlier recognition of patients with sJIA-LD at risk of adverse reactions to biologics. Early detection should help to avoid repeated treatments that are less effective and possibly deleterious and consider therapeutic approaches (eg, anti–[interleukin]-18 or [interferon]-delta–targeted treatments) that might act as a bridge therapy to control disease activity before HSCT,” wrote the author of an accompanying editorial.

TOPLINE:

Higher levels of environmental metals in urine are associated with poorer cognitive performance and an increased risk for dementia, new research suggests.

METHODOLOGY:

• This multicenter prospective cohort study included 6303 participants from six US study centers from 2000 to 2002, with follow-up through 2018.
• Participants were aged 45-84 years (median age at baseline, 60 years; 52% women) and were free of diagnosed cardiovascular disease.
• Researchers measured urinary levels of arsenic, cadmium, cobalt, copper, lead, manganese, tungsten, uranium, and zinc.
• Neuropsychological assessments included the Digit Symbol Coding, Cognitive Abilities Screening Instrument, and Digit Span tests.
• The median follow-up duration was 11.7 years for participants with dementia and 16.8 years for those without; 559 cases of dementia were identified during the study.

TAKEAWAY:

• Lower Digit Symbol Coding scores were associated with higher urinary concentrations of arsenic (mean difference [MD] in score per interquartile range [IQR] increase, –0.03), cobalt (MD per IQR increase, –0.05), copper (MD per IQR increase, –0.05), uranium (MD per IQR increase, –0.04), and zinc (MD per IQR increase, –0.03).
• Effects for cobalt, uranium, and zinc were stronger in apolipoprotein epsilon 4 allele (APOE4) carriers vs noncarriers.
• Higher urinary levels of copper were associated with lower Digit Span scores (MD, –0.043) and elevated levels of copper (MD, –0.028) and zinc (MD, –0.024) were associated with lower global cognitive scores.
• Individuals with urinary levels of the nine-metal mixture at the 95th percentile had a 71% higher risk for dementia compared to those with levels at the 25th percentile, with the risk more pronounced in APOE4 carriers than in noncarriers (MD, –0.30 vs –0.10, respectively).

IN PRACTICE:

“We found an inverse association of essential and nonessential metals in urine, both individually and as a mixture, with the speed of mental operations, as well as a positive association of urinary metal levels with dementia risk. As metal exposure and levels in the body are modifiable, these findings could inform early screening and precision interventions for dementia prevention based on individuals’ metal exposure and genetic profiles,” the investigators wrote.

 

SOURCE:

The study was led by Arce Domingo-Relloso, PhD, Columbia University Mailman School of Public Health, New York City. It was published online in JAMA Network Open.

 

LIMITATIONS:

Data may have been missed for patients with dementia who were never hospitalized, died, or were lost to follow-up. The dementia diagnosis included nonspecific International Classification of Diseases codes, potentially leading to false-positive reports. In addition, the sample size was not sufficient to evaluate the associations between metal exposure and cognitive test scores for carriers of two APOE4 alleles.

 

DISCLOSURES:

The study was supported by the National Heart, Lung, and Blood Institute. Several authors reported receiving grants from the National Institutes of Health and consulting fees, editorial stipends, teaching fees, or unrelated grant funding from various sources, which are fully listed in the original article.

The Food and Drug Administration (FDA) has approved the obesity treatment tirzepatide (Zepbound, Eli Lilly) for treating moderate to severe obstructive sleep apnea (OSA) in adults with obesity.

The new indication is for use in combination with reduced-calorie diet and increased physical activity. The once-weekly injectable is the first-ever drug treatment for OSA. Until now, OSA treatment has focused on mechanical support during sleep in the form of positive airway pressure (PAP) therapy. 

“Today’s approval marks the first drug treatment option for certain patients with obstructive sleep apnea,” said Sally Seymour, MD, director of the Division of Pulmonology, Allergy, and Critical Care in the FDA’s Center for Drug Evaluation and Research. “This is a major step forward for patients with obstructive sleep apnea.”

Excess weight is a major risk factor for OSA, in which the upper airways become blocked multiple times during sleep and obstruct breathing. The condition causes loud snoring, recurrent awakenings, and daytime sleepiness. It is also associated with cardiovascular disease.

Tirzepatide, a dual glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide receptor agonist, was initially approved with brand name Mounjaro in May 2022 for the treatment of type 2 diabetes, and as Zepbound for weight loss in November 2023.

The new OSA approval was based on two phase 3, double-blind randomized controlled trials, SURMOUNT-OSA, in patients with obesity and moderate to severe OSA, conducted at 60 sites in nine countries. Results from both were presented in June 2024 at the annual Scientific Sessions of the American Diabetes Association and were simultaneously published in The New England Journal of Medicine.

The first trial enrolled 469 participants who were unable or unwilling to use PAP therapy, while the second included 234 who had been using PAP for at least 3 months and planned to continue during the trial. In both, the participants randomly received either 10 mg or 15 mg of tirzepatide or placebo once weekly for 52 weeks.

At baseline, 65%-70% of participants had severe OSA, with more than 30 events/h on the apnea-hypopnea index (AHI) and a mean of 51.5 events/h. By 52 weeks, those randomized to tirzepatide had 27-30 fewer events/h, compared with 4-6 fewer events/h for those taking placebo. In addition, significantly more of those on tirzepatide achieved OSA remission or severity reduction to mild.

Those randomized to tirzepatide also averaged up to 20% weight loss, significantly more than with placebo. “The improvement in AHI in participants with OSA is likely related to body weight reduction with Zepbound,” according to an FDA statement.

Side effects of tirzepatide include nausea, diarrhea, vomiting, constipation, abdominal discomfort and pain, injection site reactions, fatigue, hypersensitivity reactions (typically fever and rash), burping, hair loss, and gastroesophageal reflux disease.

In an editorial accompanying The New England Journal of Medicine publication of the SURMOUNT-OSA results, Sanjay R. Patel, MD, wrote: “The potential incorporation of tirzepatide into treatment algorithms for obstructive sleep apnea should include consideration of the challenges of adherence to treatment and the imperative to address racial disparities in medical care.”

Patel, who is professor of medicine and epidemiology at the University of Pittsburgh in Pennsylvania, and medical director of the University of Pittsburgh Medical Center’s Comprehensive Sleep Disorders program, pointed out that suboptimal adherence to continuous PAP therapy has been a major limitation, but that adherence to the GLP-1 drug class has also been suboptimal.

“Although adherence to tirzepatide therapy in the SURMOUNT-OSA trial was high, real-world evidence suggests that nearly 50% of patients who begin treatment with a GLP-1 receptor agonist for obesity discontinue therapy within 12 months. Thus, it is likely that any incorporation of tirzepatide into treatment pathways for obstructive sleep apnea will not diminish the importance of long-term strategies to optimize adherence to treatment.”

Moreover, Patel noted, “racial disparities in the use of GLP-1 receptor agonists among patients with diabetes arouse concern that the addition of tirzepatide as a treatment option for obstructive sleep apnea without directly addressing policies relative to coverage of care will only further exacerbate already pervasive disparities in clinical care for obstructive sleep apnea.”

Patel reported consulting for Apnimed, Bayer Pharmaceuticals, Lilly USA, NovaResp Technologies, Philips Respironics, and Powell Mansfield. He is a fiduciary officer of BreathPA.

Laura Vater remembers sneaking into her home after 12-hour night shifts during medical training while her husband distracted their toddler. The stealthy tag-teaming effort helped her get enough undisturbed sleep before returning to an Indiana University hospital the following night to repeat the pattern.

“He would pretend to take out the trash when I pulled in,” said Vater, MD, now a gastrointestinal oncologist and assistant professor of medicine at IU Health Simon Cancer Center in Indianapolis. “I would sneak in so she [their daughter] wouldn’t see me, and then he would go back in.”

For Vater, prioritizing sleep during the day to combat sleep deprivation common among doctors-in-training on night shifts required enlisting a supportive spouse. It’s just one of the tips she and a few chief residents shared with this news organization for staying sharp and healthy during overnight rotations.

While the pace of patient rounds may slow from the frenetic daytime rush, training as a doctor after the sun goes down can be quite challenging for residents, they told this news organization. From sleep deprivation working while the rest of us slumbers to the after-effects of late-night caffeine, learning to manage night rotations requires a balance of preparation and attention to personal health while caring for others, the residents and adviser said.

Compromised sleep is one of the biggest hurdles residents have to overcome. Sleep loss comes with risks to cardiovascular disease and type 2 diabetes, among other heath conditions, according to Medscape Medical News reports. And night shift workers  who sleep 6 or fewer hours a night have at least one sleep disorder.

Sleep deprivation associated with overnight call schedules also can worsen a resident’s mood and motivation while impairing their judgment, leading to medical errors, according to a new study published in JAMA Open Network. The study proposed shorter consecutive night shifts and naps as ways to offset the results of sleep loss, especially for interns or first-year residents. 

Residency programs recently have been experimenting with shorter call schedules.

 

Catching Zzs

Working the night shift demands a disciplined sleep schedule, said Nat deQuillfeldt, MD, a Denver Health chief resident in the University of Colorado’s internal medicine residency program.

“When I was on night admissions, I was very strict about going to sleep at 8 AM and waking at 3 PM every single day. It can be very tempting to try to stay up and spend time with loved ones, but my husband and I both prioritized my physical well-being for those weeks,” said deQuillfeldt, a PGY-4 resident. “It was especially challenging for me because I had to commute about 50 minutes each way and without such a rigid schedule I would have struggled to be on time.”

deQuillfeldt doesn’t have young children at home, a noisy community, or other distractions to interrupt sleep during the day. But it was still difficult for her to sleep while the sun was out. “I used an eye mask and ear plugs but definitely woke up more often than I would at night.”

Blackout curtains may have helped, she added.

“Without adequate sleep, your clinical thinking is not as sharp. When emergencies happen overnight, you’re often the first person to arrive and need to be able to make rapid, accurate assessments and decisions.”

As a chief resident, she chooses never to sleep during night shifts.

“I personally didn’t want to leave my interns alone or make them feel like they were waking me up or bothering me if they needed help, and I also didn’t want to be groggy in case of a rapid response or code blue.”

But napping on night shift is definitely possible, deQuillfeldt said. Between following up on overnight lab results, answering nurses’ questions, and responding to emergencies, she found downtime on night shift to eat and hydrate. She believes others can catch an hour or 2 of shut eye, even if they work in the intensive care unit, or 3-4 hours on rare quiet nights.

Vater suggests residents transitioning from daytime work to night shift prepare by trying to catch an afternoon nap, staying up later the night before the change, and banking sleep hours in advance.

When he knows he’s starting night shifts, Apurva Popat, MD, said he tries to go to sleep an hour or so later nights before to avoid becoming sleep deprived. The chief resident of internal medicine at Marshfield Clinic Health System in Marshfield, Wisconsin, doesn’t recommend sleeping during the night shift.

“I typically try not to sleep, even if I have time, so I can go home and sleep later in the morning,” said Popat, a PGY-3 resident.

To help him snooze, he uses blackout curtains and a fan to block out noise. His wife, a first-year internal medicine intern, often works a different shift, so she helps set up his sleeping environment and he reciprocates when it’s her turn for night shifts.

Some interns may need to catch a 20- to 30-minute nap on the first night shift, he said.

Popat also seeks out brighter areas of the hospital, such as the emergency department, where there are more people and colleagues to keep him alert.

Lack of sleep makes it even more difficult to eat healthy on night shift, said Vater, who advises residents about wellness issues at IU and on social media.

“When you are sleep deprived, when you do not get enough sleep, you eat but you don’t feel full,” she said. “It’s hard to eat well on night shift. It’s harder if you go to the break room and there’s candy and junk food.”

Vater said that, as a resident, she brought a lunch bag to the hospital during night shifts. “I never had time to prep food, so I’d bring a whole apple, a whole orange, a whole avocado or nuts. It allowed me to eat more fruits and vegetables than I normally would.”

She advises caution when considering coffee to stay awake, especially after about 9 PM, which could interfere with sleep residents need later when they finish their shifts. Caffeine may help in the moment, but it prevents deep sleep, Vater said. So when residents finally get sleep after their shifts, they may wake up feeling tired, she said.

To avoid sleepiness, Popat brings protein shakes with him to night shifts. They stave off sugar spikes and keep his energy level high, he said. He might have a protein shake and fruit before he leaves home and carry his vegetarian dinner with him to eat in the early morning hours when the hospital is calm.

Eating small and frequent meals also helps ward off sleepiness, deQuillfeldt said.

 

Take the Stairs

Trying to stay healthy on night shifts, Vater also checked on patients by taking the stairs. “I’d set the timer on my phone for 30 minutes and if I got paged at 15, I’d pause the timer and reset it if I had a moment later. I’d get at least 30 minutes in, although not always continuous. I think some activity is better than none.”

Vater said her hospital had a gym, but it wasn’t practical for her because it was further away from where she worked. “Sometimes my coresidents would be more creative, and we would do squats.”

Popat tries to lift weights 2 hours before his night shift, but he also takes short walks between patients’ rooms in the early morning hours when it’s quietest. He also promotes deep breathing to stay alert.

 

Ask for a Ride

Vater urges those coming off night shifts, especially those transitioning for the first time from daytime rotations, not to drive if they’re exhausted. “Get an Uber. ... Make sure you get a ride home.”

The CU residency program covers the cost of a ridesharing service when doctors-in-training are too tired to drive home, deQuillfeldt said. “We really try to encourage people to use this to reduce the risk of car accidents.”

 

Promoting Mental Health

The residency program also links residents with primary care and mental health services. People who really struggle with shift work sleep disorder may qualify for medications to help them stay awake overnight, in addition to sleep hygiene apps and sleep aides.

“Night shifts can put a strain on mental health, especially when you’re only working, eating, and sleeping and not spending any time with family and friends,” deQuillfeldt said. “My husband works late afternoons, so we often would go weeks seeing each other for 15-20 minutes a day.”

“Sleeping when the sun is out often leads to a lack of light exposure which can compound the problem. Seeking mental health support early is really important to avoiding burnout,” she said.

She also recommended planning a fun weekend activity, trip, or celebration with friends or family after night shifts end “so you have something to look forward to…It’s so important to have a light at the end of the tunnel, which will allow you to enjoy the sense of accomplishment even more.”

Laura Vater remembers sneaking into her home after 12-hour night shifts during medical training while her husband distracted their toddler. The stealthy tag-teaming effort helped her get enough undisturbed sleep before returning to an Indiana University hospital the following night to repeat the pattern.

“He would pretend to take out the trash when I pulled in,” said Vater, MD, now a gastrointestinal oncologist and assistant professor of medicine at IU Health Simon Cancer Center in Indianapolis. “I would sneak in so she [their daughter] wouldn’t see me, and then he would go back in.”

For Vater, prioritizing sleep during the day to combat sleep deprivation common among doctors-in-training on night shifts required enlisting a supportive spouse. It’s just one of the tips she and a few chief residents shared with this news organization for staying sharp and healthy during overnight rotations.

While the pace of patient rounds may slow from the frenetic daytime rush, training as a doctor after the sun goes down can be quite challenging for residents, they told this news organization. From sleep deprivation working while the rest of us slumbers to the after-effects of late-night caffeine, learning to manage night rotations requires a balance of preparation and attention to personal health while caring for others, the residents and adviser said.

Compromised sleep is one of the biggest hurdles residents have to overcome. Sleep loss comes with risks to cardiovascular disease and type 2 diabetes, among other heath conditions, according to Medscape Medical News reports. And night shift workers  who sleep 6 or fewer hours a night have at least one sleep disorder.

Sleep deprivation associated with overnight call schedules also can worsen a resident’s mood and motivation while impairing their judgment, leading to medical errors, according to a new study published in JAMA Open Network. The study proposed shorter consecutive night shifts and naps as ways to offset the results of sleep loss, especially for interns or first-year residents. 

Residency programs recently have been experimenting with shorter call schedules.

 

Catching Zzs

Working the night shift demands a disciplined sleep schedule, said Nat deQuillfeldt, MD, a Denver Health chief resident in the University of Colorado’s internal medicine residency program.

“When I was on night admissions, I was very strict about going to sleep at 8 AM and waking at 3 PM every single day. It can be very tempting to try to stay up and spend time with loved ones, but my husband and I both prioritized my physical well-being for those weeks,” said deQuillfeldt, a PGY-4 resident. “It was especially challenging for me because I had to commute about 50 minutes each way and without such a rigid schedule I would have struggled to be on time.”

deQuillfeldt doesn’t have young children at home, a noisy community, or other distractions to interrupt sleep during the day. But it was still difficult for her to sleep while the sun was out. “I used an eye mask and ear plugs but definitely woke up more often than I would at night.”

Blackout curtains may have helped, she added.

“Without adequate sleep, your clinical thinking is not as sharp. When emergencies happen overnight, you’re often the first person to arrive and need to be able to make rapid, accurate assessments and decisions.”

As a chief resident, she chooses never to sleep during night shifts.

“I personally didn’t want to leave my interns alone or make them feel like they were waking me up or bothering me if they needed help, and I also didn’t want to be groggy in case of a rapid response or code blue.”

But napping on night shift is definitely possible, deQuillfeldt said. Between following up on overnight lab results, answering nurses’ questions, and responding to emergencies, she found downtime on night shift to eat and hydrate. She believes others can catch an hour or 2 of shut eye, even if they work in the intensive care unit, or 3-4 hours on rare quiet nights.

Vater suggests residents transitioning from daytime work to night shift prepare by trying to catch an afternoon nap, staying up later the night before the change, and banking sleep hours in advance.

When he knows he’s starting night shifts, Apurva Popat, MD, said he tries to go to sleep an hour or so later nights before to avoid becoming sleep deprived. The chief resident of internal medicine at Marshfield Clinic Health System in Marshfield, Wisconsin, doesn’t recommend sleeping during the night shift.

“I typically try not to sleep, even if I have time, so I can go home and sleep later in the morning,” said Popat, a PGY-3 resident.

To help him snooze, he uses blackout curtains and a fan to block out noise. His wife, a first-year internal medicine intern, often works a different shift, so she helps set up his sleeping environment and he reciprocates when it’s her turn for night shifts.
