By this summer, state employees in Florida covered by state group health insurance plans should have access to free annual skin cancer screenings.

On March 1, 2024, legislation was unanimously passed by both chambers of the state legislature that will provide for the free screenings for this group as of July 1. Some 321,000 state employees would be eligible, at a cost of about $357,000 per year, according to a legislative analysis. Gov. Ron DeSantis (R) has received and is expected to sign the bill.

The analysis concluded that the bill would have a “significant negative fiscal impact on the state employee group health plan,” as screenings will ultimately reduce cancer incidence and related morbidity and mortality.

The screenings aim to provide access to patients who may think they might not be able to afford a visit or who may have other perceived or real barriers to going for a skin check, said Sima Jain, MD, president of the Florida Academy of Dermatology. “It’s really meant to give patients access who need it,” said Dr. Jain, a dermatologist in private practice in Orlando.

The goal is early detection. “If I do a simple excision on a melanoma and we catch it early, it’s done, it’s cured,” Dr. Jain told this news organization. “It’s a win-win. We catch it early and insurance companies pay less money,” she said.

An effort to have all insurers in the state provide free screenings failed in 2023. 

From 2016 to 2020, Florida had a higher overall incidence of melanoma at 25.4 per 100,000 than the national average of 22.5, according to the National Cancer Institute. The state had some 7500 cases of melanoma each year during that period. The incidence rate in some Florida counties is as high as 32.7-45.6 per 100,000.

The Florida legislation will allow physician assistants and advanced practice nurses who operate under the supervision of a dermatologist to conduct the screenings.

It’s not clear how many state employees will access the free skin checks. “I don’t expect to see a flood of skin cancer screenings,” said Dr. Jain, noting that she hopes that it attracts primarily those at highest risk.

Once the bill is signed by the governor, Florida will be the second state to cover skin cancer screenings in some way. Illinois has required free skin cancer screening for all insured residents since 2020.

After PsA onset, early diagnosis and management leads to better long-term outcomes. These prior observations were confirmed in a study by Snoeck Henkemans and colleagues that included 708 newly diagnosed patients with PsA naive to disease-modifying antirheumatic drugs (DMARD) who were followed up for 3 years or more. Patients with a short (<12 weeks) vs long delay (>1 year) in PsA diagnosis after symptom onset were more likely to achieve minimum disease activity (OR 2.55; 95% CI 1.37-4.76). Thus, longer delay in diagnosing PsA is associated with worse clinical outcomes.

Bimekizumab is a novel biologic therapy that inhibits interleukins (IL)-17A and -17F and is efficacious in the treatment of psoriasis, PsA, and axial spondyloarthritis. However, the effectiveness in PsA vis-à-vis other IL-17A inhibitors is not known. In the absence of a formal head-to-head study, matching-adjusted indirect comparisons is a method to evaluate comparative effectiveness. Such a study by Mease and colleagues included the data of patients with PsA who were biological DMARD–naive or who had an inadequate response to tumor necrosis factor inhibitors (TNFi-IR), and who received bimekizumab from the BE OPTIMAL (n = 236) and BE COMPLETE (n = 146) trials and secukinumab from the FUTURE 2 trial (n = 200). They demonstrated that, in the biological DMARD–naive subgroup, the probability of achieving at least 70% improvement in American College of Rheumatology (ACR) response was two times higher with bimekizumab (160 mg every 4 weeks) vs secukinumab (150 mg or 300 mg every 4 weeks) at week 52. In the TNFi-IR subgroup, bimekizumab had a greater likelihood of response compared with 150 mg secukinumab for ACR20, ACR70, and minimal disease activity outcomes and a greater likelihood of response compared with 300 mg secukinumab for ACR50 and minimal disease activity. Thus, bimekizumab is at least as effective as secukinumab in PsA. Formal head-to-head studies comparing bimekizumab with other IL-17A inhibitors are required.

Distal interphalangeal (DIP) joint involvement is an important manifestation of PsA and is closely related to nail dystrophy in the adjacent nail. Ixekizumab is another biologic that targets IL-17A. In a post hoc analysis of the SPIRIT-H2H study, McGonagle and colleagues confirmed that over 96% of patients with PsA and simultaneous DIP joint involvement reported adjacent nail psoriasis. When compared with adalimumab, ixekizumab led to greater improvements in DIP involvement and adjacent nail psoriasis as early as week 12 (38.8% vs 28.4%; P < .0001), with improvements sustained up to week 52 (64.9% vs 57.5%; P = .0055). This probably reflects a greater effectiveness of IL-17A inhibition in treating skin and nail psoriasis compared with TNFi.

Finally, in a population-based retrospective cohort study that included 13,905 patients with PsA (n = 1672) or rheumatoid arthritis (n = 12,233) who did not have any previous history of major adverse cardiovascular events (MACE), Meng and colleagues showed that the incidence rates of MACE were similar in patients with PsA and rheumatoid arthritis. Thus, cardiovascular risk management should be similarly aggressive in patients with PsA and rheumatoid arthritis.

A positive family history of cancer and obesity are established risk factors for development of breast cancer among women.^[4,5] A population-based cohort study that included 15,055 Chinese women evaluated the association and interaction between body mass index (BMI) and family history of cancer on the risk for breast cancer (Cao et al). The incidence risk for breast cancer was highest in the group with obesity vs the group with normal weight (adjusted HR 2.09; 95% CI 1.42-3.07), and those with a family history of cancer also had an increased risk vs those without a family history of cancer (adjusted HR 1.63; 95% CI 1.22-2.49). Furthermore, women with a BMI ≥ 24 and family history of cancer had a higher risk for breast cancer development compared with women with a BMI < 24 and no family history of cancer (adjusted HR 2.06; 95% CI 1.39-3.06). This study indicates a heightened breast cancer risk when cancer family history and obesity coexist, suggesting the importance of addressing modifiable risk factors and targeting lifestyle interventions in this population.

Triple-negative breast cancer (TNBC), although exhibiting its own heterogeneity, has various features that differentiate this subtype from luminal breast cancers. For example, TNBC generally has a more aggressive course, increased responsiveness to chemotherapy, and earlier pattern of recurrence compared with hormone receptor–positive disease. Prior studies have also shown that established breast cancer risk factors reflect those for the luminal A subtype, whereas those for TNBC are less consistent.^[6] A meta-analysis that included 33 studies evaluated the association between traditional breast cancer risk factors and TNBC incidence (Kumar et al). Family history (odds ratio [OR] 1.55; 95% CI 1.34-1.81; P < .001), longer duration of oral contraceptive use (OR 1.29; 95% CI 1.08-1.55; P < .001), and higher breast density (OR 2.19; 95% CI 1.67-2.88; P < .001) were significantly associated with an increased risk for TNBC. Factors including later age at menarche, later age at first birth, and breastfeeding were associated with reduced risk for TNBC. Furthermore, there was no significant association with parity, menopausal hormone therapy, alcohol, smoking, and BMI. This study highlights distinct risk factors that may contribute to a higher risk for TNBC, and future research will be valuable to better elucidate the mechanisms at play and to further understand the differences within this subtype itself.

The investigational bispecific T-cell engager tarlatamab achieved durable responses and clinically meaningful survival outcomes in patients with small-cell lung cancer (SCLC), particularly at lower doses, according to a follow-up analysis of the phase 1 DeLLphi-300 trial.

Most patients with central nervous system tumors also sustained tumor shrinkage long after receiving radiotherapy, providing “encouraging evidence” of the new agent’s intracranial activity, said study presenter Horst-Dieter Hummel, MD, Comprehensive Cancer Center Mainfranken, Würzburg, Germany.

The research was presented at the European Lung Cancer Congress 2024 on March 22.

Tarlatamab targets cancer cells that express the delta-like ligand 3 (DLL3), which occurs infrequently on normal cells but on most SCLC cells. 

Data from the phase 1 and phase 2 DeLLphi trials, published last year, showed the compound achieved “encouraging clinical activity” in pretreated patients, said Dr. Hummel.

The initial phase 1 DeLLphi study found that after a median follow-up of 8.7 months, the immunotherapy led to a disease control rate of 51.4%, a median progression-free survival of 3.7 months, and median overall survival of 13.2 months.

At the meeting, Dr. Hummel reported longer-term outcomes from the phase 1 study over a median of 12.1 months as well as intracranial activity in patients who received clinically relevant doses of tarlatamab, defined as ≥ 10 mg.

The 152 patients included in the analysis had a median of two prior lines of therapy; 76.3% had undergone radiotherapy, and 63.2% had received immunotherapy. Liver metastases were present in 42.1% of patients, and 25.0% had brain metastases.

Doses varied among participants, with 76 patients (50.0%) receiving 100 mg, 32 (21.0%) receiving 100 mg via extended intravenous infusion, 17 (11.2%) receiving 10 mg, and 8 (5.3%) receiving 30 mg.

The overall objective response rate was 25.0%, with a median duration of response of 11.2 months. Among patients given the 10-mg dose, the objective response rate was higher, at 35.3%, as was the median duration of response, at 14.9 months.

Tarlatamab was associated with a median overall survival of 17.5 months, with 57.9% of patients alive at 12 months. Patients receiving the 10 mg dose had a better median overall survival of 20.3 months.

Of the 16 patients with analyzable central nervous system tumors, 62.5% experienced tumor shrinkage by ≥ 30% and 87.5% experienced intracranial disease control, which lasted for a median of 7.4 months.

In this follow-up study, tarlatamab demonstrated “clinically meaningful survival outcomes in patients with previously treated SCLC, particularly with the 10 mg dose,” Dr. Hummel concluded in his presentation.

No new safety signals emerged, though almost all patients did experience tarlatamab-related adverse events (94.8% for doses > 10 mg and 100% of patients with 10 mg doses). Overall, 66.4% of the total cohort experienced cytokine release syndrome of any grade, and 11.8% developed immune effector cell-associated neurotoxicity syndrome. 

Discontinuation due to treatment-related adverse events occurred in 9 patients overall, and adverse events that led to dose interruption or reduction occurred in 32 patients overall. 

“After many efforts at DLL3 targeting, we finally have an agent that shows activity and efficacy, and with convincing data,” said Jessica Menis, MD, a medical oncologist at the oncology department of the University Hospital of Verona, Italy, who was not involved in the study. The intracranial activity of tarlatamab “needs to be further evaluated in untreated patients,” Dr. Menis noted, because the study included only patients with stable, treated brain metastases.

And given the high rates of adverse events, Dr. Menis cautioned that adverse event management “will be a challenge.”

On X (Twitter), Tom Newsom-Davis, MBBS, PhD, a consultant in medical oncology at Chelsea and Westminster Hospital, London, said that tarlatamab is “not a straightforward drug to use,” highlighting the occurrence of cytokine release syndrome.

“But in this significantly pretreated population and in this hard-to-treat tumor type,” the rate and duration of responses seen with the extended follow-up are ‘impressive’,” he added.

DeLLphi-300, 301, and 304 were funded by Amgen Inc. Dr. Hummel declared relationships with several companies, including Amgen, Bristol Myers Squibb, AstraZeneca, Celgene, Merck, Novartis, Daiichi Sankyo, and Roche. Dr. Menis declared relationships with AstraZeneca, BMS, MSD, Roche, and Novartis.

The investigational bispecific T-cell engager tarlatamab achieved durable responses and clinically meaningful survival outcomes in patients with small-cell lung cancer (SCLC), particularly at lower doses, according to a follow-up analysis of the phase 1 DeLLphi-300 trial.

Most patients with central nervous system tumors also sustained tumor shrinkage long after receiving radiotherapy, providing “encouraging evidence” of the new agent’s intracranial activity, said study presenter Horst-Dieter Hummel, MD, Comprehensive Cancer Center Mainfranken, Würzburg, Germany.

The research was presented at the European Lung Cancer Congress 2024 on March 22.

Tarlatamab targets cancer cells that express the delta-like ligand 3 (DLL3), which occurs infrequently on normal cells but on most SCLC cells. 

Data from the phase 1 and phase 2 DeLLphi trials, published last year, showed the compound achieved “encouraging clinical activity” in pretreated patients, said Dr. Hummel.

The initial phase 1 DeLLphi study found that after a median follow-up of 8.7 months, the immunotherapy led to a disease control rate of 51.4%, a median progression-free survival of 3.7 months, and median overall survival of 13.2 months.

At the meeting, Dr. Hummel reported longer-term outcomes from the phase 1 study over a median of 12.1 months as well as intracranial activity in patients who received clinically relevant doses of tarlatamab, defined as ≥ 10 mg.

The 152 patients included in the analysis had a median of two prior lines of therapy; 76.3% had undergone radiotherapy, and 63.2% had received immunotherapy. Liver metastases were present in 42.1% of patients, and 25.0% had brain metastases.

Doses varied among participants, with 76 patients (50.0%) receiving 100 mg, 32 (21.0%) receiving 100 mg via extended intravenous infusion, 17 (11.2%) receiving 10 mg, and 8 (5.3%) receiving 30 mg.

The US Food and Drug Administration (FDA) has approved sotatercept (Winrevair, Merck), for the treatment of adults with pulmonary arterial hypertension (PAH), World Health Organization (WHO) Group 1, to increase exercise capacity, improve WHO functional class, and reduce the risk for clinical worsening events.

Sotatercept, which had breakthrough therapy designation, is a first-in-class activin signaling inhibitor that works by improving the balance between pro- and antiproliferative signaling to regulate the vascular cell proliferation that underlies PAH.

“Sotatercept added to background therapy has the potential to become a new standard-of-care option for patients with pulmonary arterial hypertension,” added coinvestigator Aaron B. Waxman, MD, PhD, executive director of the Center for Pulmonary Heart Diseases at Brigham and Women’s Hospital, Boston.

The approval was based on results of the phase 3 STELLAR study, a global, double-blind, placebo-controlled, multicenter, parallel-group clinical trial in which, 323 patients with PAH (WHO Group 1, functional class II or III) were randomly assigned 1:1 to add sotatercept or placebo to stable background therapy.

The results showed that sotatercept, administered subcutaneously every 3 weeks for 24 weeks, improved average 6-minute walk distance from baseline by a significant and clinically meaningful 40.8 meters compared with placebo for the trial’s primary efficacy endpoint (P < .001).

Sotatercept also led to significant improvement in multiple secondary outcome measures, including:

• Reduction in the risk for death from any cause or PAH clinical worsening events by 84% vs background therapy alone (number of events: 9 vs 42; hazard ratio [HR], 0.16; P < .001) 
• Improvement in FC from baseline at 24 weeks in 29% of patients compared with 14% of patients treated with placebo (P < .001) 
• Improvement in pulmonary vascular resistance (PVR), with an average 235 dyn/sec/cm⁵ reduction in PVR from baseline (P < .001) 
• Improvement from baseline in N-terminal pro–B-type natriuretic peptide (NT-proBNP) levels. The median treatment difference in NT-proBNP between sotatercept and placebo was -442 pg/mL (P < .001) 

The results were reported last year at the joint scientific sessions of the American College of Cardiology and the World Heart Federation, with simultaneous publication in The New England Journal of Medicine. 

Sotatercept injection may be administered by patients or caregivers with guidance, training, and follow-up from a healthcare provider. The recommended starting dose is 0.3 mg/kg. The recommended target dose is 0.7 mg/kg every 3 weeks.

Sotatercept may increase hemoglobin, may lead to erythrocytosis, and may decrease platelet count and lead to severe thrombocytopenia. Treatment should not be initiated if platelet count is < 50,000/mm³. 

Hemoglobin and platelets should be monitored before each dose of sotatercept for the first five doses, or longer if values are unstable, and periodically thereafter to determine if dose adjustments are required. 

Full prescribing information is available online. 

Merck estimates that sotatercept will be available for dispensing by select specialty pharmacies in the United States by the end of April 2024.

TOPLINE:

The inclusion of sugar-substitute sweeteners and sweetness enhancers in a sugar-reduced maintenance diet following weight loss improves weight maintenance as well as well-being in adults, with no increases in type 2 diabetes or cardiovascular disease risk compared with a diet excluding the sweeteners, a randomized trial showed.

The study also showed that among overweight or obese children, greater reductions in uncontrolled eating were observed among those receiving the sweeteners.

The findings counter previous reports that raised concerns about the non-sugar sweeteners, including recent research from the World Health Organization suggesting no benefits in weight control and a possible increase in the risk for type 2 diabetes or cardiovascular disease with the sweeteners.

METHODOLOGY:

• The findings are from an exploratory analysis of the multicenter, randomized SWEET trial.
• The trial involved 341 adults with overweight or obesity (aged 18-65 years, 71% women, body mass index [BMI] ≥ 25) and 38 children with overweight (aged 6-12 years, 60% girls, BMI-for-age > 85th percentile), recruited in Denmark, Spain, Greece, and the Netherlands through webpages, social media, newspapers, and registries.
• For the first 2 months of the trial, adults were instructed to follow a low-energy diet (the Cambridge Weight Plan) with the goal of achieving at least 5% weight loss, while children received dietary advice to maintain body weight.
• In the subsequent 10 months, adults as well as children were randomized to healthy diets that either consisted of less than 10% of calories from added sugar but permitted foods and drinks with sweeteners and sweetness enhancers, or the same diet but not allowing the use of the sweeteners or sweetness enhancers.
• Participants had weight, BMI, anthropometry, and risk markers for type 2 diabetes and cardiovascular disease monitored at the trial’s baseline, as well as at 2, 6, and 12 months.
• In addition, participants completed food frequency questionnaires and provided urine samples to assess biomarkers of the sweeteners, fructose and sucrose, in order to measure compliance with the dietary instructions.

TAKEAWAY:

• While the sweetener and non-sweetener groups both had decreases in consumption of products high in sugar, the reduction was significantly higher in the group that allowed use of the sweeteners (P = .002).
• In the intention-to-treat analyses, adults (n = 277) permitted sweeteners showed a small but significantly greater weight loss maintenance after 1 year than the non-sweetener group (average weight loss, 7.2 kg vs 5.6 kg; P = .029).
• Among 203 participants who completed the trial, there were no differences between the groups in terms of markers for type 2 diabetes and cardiovascular disease.
• There were also no differences between the groups in terms of subjective appetite sensations and appetite hormones in a subgroup of 104 patients.
• In an analysis of 22 children who completed the study, there were no differences in BMI-for-age z scores between sweetener and non-sweetener groups.
• In terms of effects on eating behavior, adults in the sweetener group reported greater diet satisfaction when eating out (P = .03), increased positive mood (P = .013), and reduced craving for sweet food (P = .034) at 6 months than in the non-sweetener group.
• Conversely, those receiving no sweeteners had a greater liking bias for sweet vs savory foods at 6 months (P = .023) and 12 months (P = .005).
• There were no differences between the groups in reported physical activity or quality of life.
• However, among children with higher uncontrolled eating scores at baseline, the uncontrolled eating scores at 12 months were significantly lower among children who were allowed the sugar-substitute sweeteners vs the non-sweetener children (P = .021).

IN PRACTICE:

“Our findings suggest that the inclusion of low/no energy-sweetened products may benefit children who show high levels of uncontrolled eating,” said the study’s co-lead author, Clarissa Dakin, of the Appetite Control and Energy Balance Research Group at the University of Leeds, Leeds, England, in a press statement.

“Together, these findings provide important insights for the ongoing reevaluation of food additive sweeteners by the European Food Safety Authority and other health agencies worldwide,” she said.

Coauthor Jason Halford, head of the School of Psychology at the University of Leeds, added in the press statement that “the use of low-calorie sweeteners in weight management has been questioned, in part because of the link between their use and apparent weight gain in observational studies.”

“However, increasingly, it is becoming apparent that is not the case in long-term studies,” said a study co-author in a press statement.”

SOURCE:

The findings from the two abstracts will be presented in May at the European Association for the Study of Obesity. The study abstracts were issued in advance.

LIMITATIONS:

Some of the results, particularly in children’s subgroups, were limited by the relatively low number of children, underscoring the need for future studies on the issue, the authors noted.

DISCLOSURES:

Dr. Halford has received research funding from the American Beverage Association.

• In the subsequent 10 months, adults as well as children were randomized to healthy diets that either consisted of less than 10% of calories from added sugar but permitted foods and drinks with sweeteners and sweetness enhancers, or the same diet but not allowing the use of the sweeteners or sweetness enhancers.
• Participants had weight, BMI, anthropometry, and risk markers for type 2 diabetes and cardiovascular disease monitored at the trial’s baseline, as well as at 2, 6, and 12 months.
• In addition, participants completed food frequency questionnaires and provided urine samples to assess biomarkers of the sweeteners, fructose and sucrose, in order to measure compliance with the dietary instructions.

TAKEAWAY:

• While the sweetener and non-sweetener groups both had decreases in consumption of products high in sugar, the reduction was significantly higher in the group that allowed use of the sweeteners (P = .002).
• In the intention-to-treat analyses, adults (n = 277) permitted sweeteners showed a small but significantly greater weight loss maintenance after 1 year than the non-sweetener group (average weight loss, 7.2 kg vs 5.6 kg; P = .029).
• Among 203 participants who completed the trial, there were no differences between the groups in terms of markers for type 2 diabetes and cardiovascular disease.
• There were also no differences between the groups in terms of subjective appetite sensations and appetite hormones in a subgroup of 104 patients.
• In an analysis of 22 children who completed the study, there were no differences in BMI-for-age z scores between sweetener and non-sweetener groups.
• In terms of effects on eating behavior, adults in the sweetener group reported greater diet satisfaction when eating out (P = .03), increased positive mood (P = .013), and reduced craving for sweet food (P = .034) at 6 months than in the non-sweetener group.
• Conversely, those receiving no sweeteners had a greater liking bias for sweet vs savory foods at 6 months (P = .023) and 12 months (P = .005).
• There were no differences between the groups in reported physical activity or quality of life.
• However, among children with higher uncontrolled eating scores at baseline, the uncontrolled eating scores at 12 months were significantly lower among children who were allowed the sugar-substitute sweeteners vs the non-sweetener children (P = .021).

IN PRACTICE:

“Our findings suggest that the inclusion of low/no energy-sweetened products may benefit children who show high levels of uncontrolled eating,” said the study’s co-lead author, Clarissa Dakin, of the Appetite Control and Energy Balance Research Group at the University of Leeds, Leeds, England, in a press statement.

“Together, these findings provide important insights for the ongoing reevaluation of food additive sweeteners by the European Food Safety Authority and other health agencies worldwide,” she said.

Coauthor Jason Halford, head of the School of Psychology at the University of Leeds, added in the press statement that “the use of low-calorie sweeteners in weight management has been questioned, in part because of the link between their use and apparent weight gain in observational studies.”

“However, increasingly, it is becoming apparent that is not the case in long-term studies,” said a study co-author in a press statement.”

SOURCE:

The findings from the two abstracts will be presented in May at the European Association for the Study of Obesity. The study abstracts were issued in advance.

LIMITATIONS:

Some of the results, particularly in children’s subgroups, were limited by the relatively low number of children, underscoring the need for future studies on the issue, the authors noted.

DISCLOSURES:

Dr. Halford has received research funding from the American Beverage Association.

Starting an exercise regimen with others can be a powerful fitness motivator, and new research spotlights the strategy’s particular importance for older adults.

In a randomized clinical trial published in JAMA Network Open, older adults who talked with peers about their exercise program were able to increase and sustain physical activity levels much better than those who focused on self-motivation and setting fitness goals.

Such self-focused — or “intrapersonal” — strategies tend to be more common in health and fitness than interactive, or “interpersonal,” ones, the study authors noted. Yet, research on their effectiveness is limited. Historically, intrapersonal strategies have been studied as part of a bundle of behavioral change strategies — a common limitation in research — making it difficult to discern their individual value.

“We’re not saying that intrapersonal strategies should not be used,” said study author Siobhan McMahon, PhD, associate professor and codirector of the Center on Aging Science and Care at the University of Minnesota, in Minneapolis, Minnesota, “but this study shows that interpersonal strategies are really important.”

Low physical activity among older adults is linked with “disability, difficulty managing chronic conditions, and increased falls and related injuries,” the authors wrote. Exercise can be the antidote, yet fewer than 16% of older adults meet the recommended guidelines (150 minutes of moderate aerobic activity and two muscle-strengthening sessions per week).

The study builds on previous research that suggests interpersonal strategies could help change that by encouraging more older adults to move.
 

Intrapersonal vs Interpersonal Behavior Change Strategies

More than 300 participants aged 70 years and older who did not meet physical activity guidelines were given a wearable fitness tracker and an exercise program and randomly split into four groups:

• One using intrapersonal behavior change strategies
• Another using interpersonal strategies
• A group combining both intrapersonal and interpersonal strategies
• A control group that received neither intervention

For 8 weeks, all participants exercised in meet-ups and discussed their progress in their groups. Afterward, they were left to their own devices and monitored for the remainder of the year.

“The intrapersonal strategies group involved personal reflection,” said Dr. McMahon. They set personal goals (increasing daily step count or exercise repetitions) and developed action plans for implementing physical activity into their daily routines.

“The interpersonal group involved more peer-to-peer conversation, collaborative learning, and sharing,” said Dr. McMahon. Participants talked among themselves about how they could sustain doing the prescribed exercises at home. “Through those conversations, they learned and experimented,” Dr. McMahon said. They problem-solved, determining what barriers might stop them from exercising and brainstorming ways around them.

The researchers evaluated the participants after 1 week, 6 months, and 12 months. The interpersonal group exhibited significant increases in physical activity — including light, moderate, and vigorous activity — for the entire year. They increased their average physical activity per day by 21-28 minutes and their daily step count by 776-1058.

The intrapersonal group, meanwhile, exhibited no significant changes in total physical activity. (The third experimental group, the intrapersonal plus interpersonal condition, had results similar to the interpersonal one.)

The results echoed the findings of a similar study Dr. McMahon conducted in 2017. “We followed people over a longer period of time in this [new] study,” she said, “12 months instead of 6 months. This is important in physical activity studies because a lot of evidence shows that after 6 months, people’s activity drops off.”
 

How Socializing Promotes Exercise Compliance

Research on the effectiveness of exercise in social groups dates back as far as the 19th century. It’s called the social facilitation theory: The idea that people will make an increased effort as a result of the real, imagined, or implied presence of others.

“Norman Triplett was a scientist who studied indoor cyclists, and he came up with the social facilitation theory in 1898,” said Robert Linkul, CSCS*D, who sits on the National Strength and Conditioning Association’s board of directors and specializes in exercise for older adults. “He noticed that during relays, the first cyclist would get slower as he fatigued, but as soon as his teammate came out, his last lap would be faster than his previous two laps. People try harder when there’s some other person present. They tend to feel pressure to perform because they don’t want to look bad.”

Dr. McMahon said the exact psychology of why socializing supports exercise isn’t clear yet but noted that talking to other people builds relationships and makes one feel connected to and involved with a community.

“I think connections between peers are really important,” said Dr. McMahon. “It goes beyond just being in the same room and doing the exercises together. It’s taking a little bit of time to talk about it. To acknowledge what they’re doing and their progress. To encourage each other and provide support.”

Some of the study participants even became friends and continued to meet on their own time over the course of the trial.

“They stayed in touch,” said Dr. McMahon. “One thing that people talked about after the study, even if they weren’t friends, was that the conversations within the meetings made them feel kind of a fellowship that helped them learn about themselves or people like them.”
 

Help Patients Find Their Own Fellowship of Active People

• Communicate the importance of exercise. During appointments, ask how the patient is doing with their exercise and listen for any obstacles to compliance, Dr. McMahon said.
• See if they have access to fitness classes. Many community-dwelling older adults do, Mr. Linkul said. If not, consider local or state agencies on aging — “in Minnesota, we have a program, Juniper,” Dr. McMahon said, that maintains a list of physical activity programs — or AARP’s free online group classes, or Silver Sneakers (free for those with eligible Medicare Advantage plans).
• Reach out to local qualified fitness professionals. Trainers with the Training the Older Adult certification (founded by Mr. Linkul) can be found here. Other qualified trainers can be found through the Functional Aging Institute, American Council on Exercise, and National Academy of Sports Medicine, Mr. Linkul said. “Many of these trainers will offer semiprivate sessions,” said Mr. Linkul, “which is usually four to eight people.” Groups of this size often facilitate better participation than larger classes. “You get more personalized attention from the instructor along with an environment that allows social engagement,” said Mr. Linkul. If you have exercise or rehab professionals in your network, you might consider reaching out to them. Some physical therapists lead activity groups, though reimbursement challenges mean they aren’t common, Dr. McMahon said.
• Prescribe short walks with a friend, family member, or neighbor. Have the person start with 30 minutes of walking or rucking (walking with a weighted backpack) most days, Mr. Linkul suggested, a recommendation that is echoed by the American College of Sports Medicine.
• Encourage patients to talk about their exercise. Even for those who prefer to exercise solo, “our studies suggest it might be helpful to have conversations with others about movement, and motivations for movement,” Dr. McMahon said. They can simply mention one idea, question, or observation related to physical activity during casual catchups or chats.
• Recommend resistance training. That goes for patients with preexisting health conditions too, Mr. Linkul said. Physicians “find out a patient has low bone mineral density, and they’ll often tell them not to pick up anything heavy because they’ll hurt themselves — and that’s the exact wrong answer,” Mr. Linkul said. A total of 32% of the participants in the JAMA Network study had cardiovascular disease, nearly 34% had osteoporosis, 70% had arthritis, and more than 20% were living with diabetes.
• Expect pushback. Encouraging older adults to exercise is hard because many are resistant to it, Mr. Linkul acknowledged. Do it anyway. Some will listen and that makes the effort worthwhile. “I try to provide as much information as I can about what happens to aging bodies if they don’t train,” said Mr. Linkul. “These people are more likely to fall, they’ll die earlier, and have a poorer quality of life. But when they start exercising, they feel better immediately.”

Electronic health records (EHRs) make providing coordinated, efficient care easier and reduce medical errors and test duplications; research has also correlated EHR adoption with higher patient satisfaction and outcomes. However, for physicians, the benefits come at a cost.

Physicians spend significantly more time in healthcare portals, making notes, entering orders, reviewing clinical reports, and responding to patient messages.

“I spend at least the same amount of time in the portal that I do in scheduled clinical time with patients,” said Eve Rittenberg, MD, primary care physician at Brigham and Women’s Hospital and assistant professor at Harvard Medical School, Boston, Massachusetts. “So, if I have a 4-hour session of seeing patients, I spend at least another 4 or more hours in the patient portal.”

The latest data showed that primary care physicians logged a median of 36.2 minutes in the healthcare portal per patient visit, spending 58.9% more time on orders, 24.4% more time reading and responding to messages, and 13% more time on chart review compared to prepandemic portal use.

“EHRs can be very powerful tools,” said Ralph DeBiasi, MD, a clinical cardiac electrophysiologist at Yale New Haven Health. “We’re still working on how to best harness that power to make us better doctors and better care teams and to take better care of our patients because their use can take up a lot of time.”
 

Portal Time Isn’t Paid Time

Sharp increases in the amount of time spent in the EHR responding to messages or dispensing medical advice via the portal often aren’t linked to increases in compensation; most portal time is unpaid.

“There isn’t specific time allocated to working in the portal; it’s either done in the office while a patient is sitting in an exam room or in the mornings and evenings outside of traditional working hours,” Dr. DeBiasi said. “I think it’s reasonable to consider it being reimbursed because we’re taking our time and effort and making decisions to help the patient.”

Compensation for portal time affects all physicians, but the degree of impact depends on their specialties. Primary care physicians spent significantly more daily and after-hours time in the EHR, entering notes and orders, and doing clinical reviews compared to surgical and medical specialties.

In addition to the outsized impact on primary care, physician compensation for portal time is also an equity issue.

Dr. Rittenberg researched the issue and found a higher volume of communication from both patients and staff to female physicians than male physicians. As a result, female physicians spend 41.4 minutes more on the EHR than their male counterparts, which equates to more unpaid time. It’s likely no coincidence then that burnout rates are also higher among female physicians, who also leave the clinical workforce in higher numbers, especially in primary care.

“Finding ways to fairly compensate physicians for their work also will address some of the equity issues in workload and the consequences,” Dr. Rittenberg said.
 

Addressing the Issue

Some health systems have started charging patients who seek medical advice via patient portals, equating the communication to asynchronous acute care or an additional care touchpoint and billing based on the length and complexity of the messages. Patient fees for seeking medical advice via portals vary widely depending on their health system and insurance.

At University of California San Francisco Health, billing patients for EHR communication led to a sharp decrease in patient messages, which eased physician workload. At Cleveland Clinic, physicians receive “productivity credits” for the time spent in the EHR that can be used to reduce their clinic hours (but have no impact on their compensation).

Changes to the Medicare Physician Fee Schedule also allow physicians to bill for “digital evaluation and management” based on the time spent in an EHR responding to patient-initiated questions and requests.

However, more efforts are needed to ease burnout and reverse the number of physicians who are seeing fewer patients or leaving medical practice altogether as a direct result of spending increasing amounts of unpaid time in the EHR. Dr. Rittenberg, who spends an estimated 50% of her working hours in the portal, had to reduce her clinical workload by 25% due to such heavy portal requirements.

“The workload has become unsustainable,” she said. “The work has undergone a dramatic change over the past decade, and the compensation system has not kept up with that change.”
 

Prioritizing Patient and Physician Experiences

The ever-expanding use of EHR is a result of their value as a healthcare tool. Data showed that the electronic exchange of information between patients and physicians improves diagnostics, reduces medical errors, enhances communication, and leads to more patient-centered care — and physicians want their patients to use the portal to maximize their healthcare.

“[The EHR] is good for patients,” said Dr. DeBiasi. “Sometimes, patients have access issues with healthcare, whether that’s not knowing what number to call or getting the right message to the right person at the right office. If [the portal] is good for them and helps them get access to care, we should embrace that and figure out a way to work it into our day-to-day schedules.”

But maximizing the patient experience shouldn’t come at the physicians’ expense. Dr. Rittenberg advocates a model that compensates physicians for the time spent in the EHR and prioritizes a team approach to rebalance the EHR workload to ensure that physicians aren’t devoting too much time to administrative tasks and can, instead, focus their time on clinical tasks.

“The way in which we provide healthcare has fundamentally shifted, and compensation models need to reflect that new reality,” Dr. Rittenberg added.

“EHRs can be very powerful tools,” said Ralph DeBiasi, MD, a clinical cardiac electrophysiologist at Yale New Haven Health. “We’re still working on how to best harness that power to make us better doctors and better care teams and to take better care of our patients because their use can take up a lot of time.”
 

Portal Time Isn’t Paid Time

Sharp increases in the amount of time spent in the EHR responding to messages or dispensing medical advice via the portal often aren’t linked to increases in compensation; most portal time is unpaid.

“There isn’t specific time allocated to working in the portal; it’s either done in the office while a patient is sitting in an exam room or in the mornings and evenings outside of traditional working hours,” Dr. DeBiasi said. “I think it’s reasonable to consider it being reimbursed because we’re taking our time and effort and making decisions to help the patient.”

Compensation for portal time affects all physicians, but the degree of impact depends on their specialties. Primary care physicians spent significantly more daily and after-hours time in the EHR, entering notes and orders, and doing clinical reviews compared to surgical and medical specialties.

In addition to the outsized impact on primary care, physician compensation for portal time is also an equity issue.

Dr. Rittenberg researched the issue and found a higher volume of communication from both patients and staff to female physicians than male physicians. As a result, female physicians spend 41.4 minutes more on the EHR than their male counterparts, which equates to more unpaid time. It’s likely no coincidence then that burnout rates are also higher among female physicians, who also leave the clinical workforce in higher numbers, especially in primary care.

“Finding ways to fairly compensate physicians for their work also will address some of the equity issues in workload and the consequences,” Dr. Rittenberg said.
 

Addressing the Issue

Some health systems have started charging patients who seek medical advice via patient portals, equating the communication to asynchronous acute care or an additional care touchpoint and billing based on the length and complexity of the messages. Patient fees for seeking medical advice via portals vary widely depending on their health system and insurance.

At University of California San Francisco Health, billing patients for EHR communication led to a sharp decrease in patient messages, which eased physician workload. At Cleveland Clinic, physicians receive “productivity credits” for the time spent in the EHR that can be used to reduce their clinic hours (but have no impact on their compensation).

Changes to the Medicare Physician Fee Schedule also allow physicians to bill for “digital evaluation and management” based on the time spent in an EHR responding to patient-initiated questions and requests.

However, more efforts are needed to ease burnout and reverse the number of physicians who are seeing fewer patients or leaving medical practice altogether as a direct result of spending increasing amounts of unpaid time in the EHR. Dr. Rittenberg, who spends an estimated 50% of her working hours in the portal, had to reduce her clinical workload by 25% due to such heavy portal requirements.

“The workload has become unsustainable,” she said. “The work has undergone a dramatic change over the past decade, and the compensation system has not kept up with that change.”
 

Prioritizing Patient and Physician Experiences

The ever-expanding use of EHR is a result of their value as a healthcare tool. Data showed that the electronic exchange of information between patients and physicians improves diagnostics, reduces medical errors, enhances communication, and leads to more patient-centered care — and physicians want their patients to use the portal to maximize their healthcare.

“[The EHR] is good for patients,” said Dr. DeBiasi. “Sometimes, patients have access issues with healthcare, whether that’s not knowing what number to call or getting the right message to the right person at the right office. If [the portal] is good for them and helps them get access to care, we should embrace that and figure out a way to work it into our day-to-day schedules.”

But maximizing the patient experience shouldn’t come at the physicians’ expense. Dr. Rittenberg advocates a model that compensates physicians for the time spent in the EHR and prioritizes a team approach to rebalance the EHR workload to ensure that physicians aren’t devoting too much time to administrative tasks and can, instead, focus their time on clinical tasks.

“The way in which we provide healthcare has fundamentally shifted, and compensation models need to reflect that new reality,” Dr. Rittenberg added.

Electronic health records (EHRs) make providing coordinated, efficient care easier and reduce medical errors and test duplications; research has also correlated EHR adoption with higher patient satisfaction and outcomes. However, for physicians, the benefits come at a cost.

Physicians spend significantly more time in healthcare portals, making notes, entering orders, reviewing clinical reports, and responding to patient messages.

“I spend at least the same amount of time in the portal that I do in scheduled clinical time with patients,” said Eve Rittenberg, MD, primary care physician at Brigham and Women’s Hospital and assistant professor at Harvard Medical School, Boston, Massachusetts. “So, if I have a 4-hour session of seeing patients, I spend at least another 4 or more hours in the patient portal.”

As a cardiologist specializing in obesity medicine, I often encounter patients who would greatly benefit from the new generation of weight loss drugs that work as glucagon-like peptide 1 (GLP-1) agonists. In the recently published SELECT trial results, for example, semaglutide (marketed by Novo Nordisk as Wegovy for weight loss and Ozempic for type 2 diabetes) demonstrated a 20% risk reduction of heart attacks and strokes in overweight and obese individuals without diabetes and with cardiovascular disease, establishing it as a cardiovascular disease–modifying medication in people without type 2 diabetes.

Unfortunately, the high demand for these new weight loss medications has resulted in a frustrating, long-lasting shortage. The manufacturers of the two FDA-approved drugs, Novo Nordisk and Eli Lilly (tirzepatide, marketed as Zepbound for weight loss and Mounjaro for type 2 diabetes), are struggling to meet the overwhelming need.

To ensure continuation of patient care, federal law allows compounding pharmacies to make “essentially a copy” of the medications that are listed as “currently in shortage” on the US Food and Drug Administration (FDA) drug shortage list. Both semaglutide and tirzepatide are on that list. For Americans who suffer from obesity and other weight-related diseases, these drugs could be a lifeline.

Despite this, the medical community has broadly criticized the utilization of compounded GLP-1 agonists, even those obtained from reputable and legitimate compounding pharmacies.

Yes, high demand has led to the emergence of unregulated companies and scammers producing substandard or counterfeit versions of these medications.

The FDA has found fraudulent products (masquerading as the weight loss drugs) and has issued warning letters to stop the distribution of illegally marketed semaglutide. “These drugs may be counterfeit, which means they could contain the wrong ingredients, contain too little, too much or no active ingredient at all, or contain other harmful ingredients,” it cautions. Some products use a similar-sounding semaglutide sodium salt, which has uncertain safety and efficacy, and had generated warnings from the FDA and state boards of pharmacy.

Many of these products are marketed directly to consumers online through websites and social media, with little to no medical oversight. This practice is a significant concern, as it may affect patient safety, and should be discouraged.

However, according to a statement from the Alliance for Pharmacy Compounding (APC), legitimate compounding pharmacies aren’t the ones selling these dubious products on the black market, particularly online. This illegal practice has garnered media attention and is sometimes incorrectly associated with legitimate pharmacy compounding.

In contrast, legal and certified versions of GLP-1 agonist medications can be obtained from well-regulated and reputable compounding pharmacies. These pharmacies must adhere to all federal and state regulations and dispense medications only with a valid prescription from a licensed physician.

Meanwhile, the APC statement notes, Novo Nordisk and Eli Lilly have sued compounding companies in several states, questioning, among other things, the purity and potency of some compounded products.

There are different designations for compounding pharmacies: 503A and 503B. 503As are state-licensed pharmacies and physicians, and 503B pharmacies are federally regulated outsourcing facilities that are strictly regulated by the FDA. This regulation, established following a 2012 fungal meningitis outbreak linked to a compounding pharmacy, ensures higher-quality control and oversight, especially for medications intended for intravenous or epidural use. These standards exceed those required for subcutaneous injections like GLP-1 analogs.

In the face of this Wild West climate, where compounded drugs may vary in their source, formulation, potency, and purity, The Obesity Society, the Obesity Medical Association, and the Obesity Action Coalition published a joint statement that advised against the use of compounded GLP-1 agonists, citing safety concerns and lack of regulatory oversight.

This stance, while aimed at ensuring patient safety, inadvertently raises a critical issue.

By completely dismissing compounded medications, experts may unintentionally bolster the black market and overlook the needs of patients who could benefit from these medications, contrary to the intentions of the exemption provided in federal law for compounding during a drug shortage. In fact, the presence of unreliable suppliers highlights the need to direct the public toward trustworthy sources, rather than imposing a total ban on medically appropriate alternatives.

The joint statement calls compounded GLP-1 agonists “counterfeit.” This inaccurate overgeneralization probably stems from a misunderstanding of the compounding process and its regulations. Legitimate and regulated pharmacies compound base GLP-1 agonists, which are “essentially a copy” of FDA-approved medications, not counterfeits. Recognizing this is crucial for maintaining trust in both compounding pharmacies and regulatory bodies.

It is correct that “the only FDA-approved manufacturers of these medications are the companies that created the active pharmaceutical ingredients — Novo Nordisk and Eli Lilly,” but the joint statement fails to mention the exemptions provided by law that allow compounding copies of the branded medications if they are on the shortage list.

Compounding pharmacies must obtain active pharmaceutical ingredients (APIs) from FDA-registered facilities, which are required to adhere to Current Good Manufacturing Practices (cGMP). This ensures the APIs’ quality, potency, and purity, crucial for the safety and efficacy of compounded medications.

Compounded drugs are not FDA approved, but they aren’t inherently unsafe. Compounded medications include critical drugs such as resuscitation medications and antibiotics, and are often used in healthcare settings, especially when there’s a shortage. This raises the question of why compounded GLP-1 agonists would be treated any differently in such scenarios.

And in the case of alternative drugs for individuals with obesity who have a higher risk for cardiovascular disease, the brand-name FDA-approved alternative may be of more concern than the compounded GLP-1 agonist. The obesity societies advise: “If you cannot find or get access to a GLP-1-based treatment now, there are other treatments available,” echoing experts. While the statement doesn’t specify the names of the alternatives, experts have advised using alternatives such as Qsymia and Contrave, despite their potential cardiovascular concerns. This recommendation to the public may not represent a responsible risk-benefit analysis.

When prescribing GLP-1 agonists for obesity treatment, doctors should consider all of the following steps to ensure patient safety and effective treatment:

Preference for FDA-approved brands: FDA-approved branded GLP-1 agonist medications should be the primary choice because of their established safety and efficacy.

Risk-benefit analysis for non–FDA-approved products: In cases where FDA-approved options are not available, doctors may consider prescribing a non–FDA-approved copy of the branded medication. Prior to this, conduct a thorough risk-benefit analysis with the patient, ensuring that they are fully informed about the potential risks and benefits of using a non–FDA-approved product.

Choosing semaglutide copies for specific cases: In patients with obesity and cardiovascular disease, the benefits of using a compounded copy of semaglutide, with its cardiovascular disease–modifying properties, may outweigh the risks compared with other FDA-approved antiobesity drugs that might pose cardiovascular risks or compared with no antiobesity treatment at all.

Informed consent and monitoring: When prescribing a non–FDA-approved version of a GLP-1 agonist, obtaining informed consent from the patient is advised. They should be made aware of the differences between the FDA-approved and nonapproved versions.

Choosing between 503A and 503B pharmacies: Prescriptions for non–FDA-approved GLP-1 agonists can be directed to either 503A or 503B compounding pharmacies. However, it’s advisable to check whether the product can be compounded by a 503B pharmacy, which is subject to an additional layer of FDA regulation, offering greater quality assurance.

Clear prescription specifications: Ensure that the prescription explicitly states that the compounded GLP-1 agonist should be the base compound without additives.

Requesting a Certificate of Analysis: To further ensure safety, request a Certificate of Analysis from the compounding pharmacy. This provides detailed quality and composition information about the product.

Ongoing monitoring: Continuously monitor the patient’s response to the medication and adjust the treatment plan as necessary, maintaining regular follow-ups.

By adhering to these guidelines, doctors can navigate the complexities of prescribing GLP-1 agonists in a way that prioritizes patient well-being, particularly in scenarios where conventional treatment options are limited.

Ongoing monitoring: Continuously monitor the patient’s response to the medication and adjust the treatment plan as necessary, maintaining regular follow-ups.

By adhering to these guidelines, doctors can navigate the complexities of prescribing GLP-1 agonists in a way that prioritizes patient well-being, particularly in scenarios where conventional treatment options are limited.

Two classes of chemicals present in common household products may impair the development of oligodendrocytes, the myelinating cells of the central nervous system (CNS), which are critical to brain development and function. However, the researchers as well as outside experts agree more research is needed before any firm conclusions can be drawn. 

Quaternary ammonium compounds, ubiquitous in disinfecting agents and personal care products, and organophosphate flame retardants, which are commonly found in household items such as furniture and electronics had “surprising effects specifically on the non-nerve cells in the brain,” said lead researcher Paul Tesar, PhD, professor and director of the Institute for Glial Sciences, Case Western Reserve University School of Medicine, Cleveland. 

“Other studies have shown that our exposures to the chemicals in disinfecting agents nearly doubled during the pandemic,” Dr. Tesar noted. The finding that quaternary ammonium chemicals in disinfecting agents are harmful to specific brain cells suggests “we need to think about our increased utilization and exposure,” he added.

The results were published online on March 25 in Nature Neuroscience. 
 

Motor Dysfunction

Exposure to various chemicals in the environment has been shown to impair brain development. However, most of this research has focused on neurons. Less is known about effects on oligodendrocytes, which form the electrical insulation around the axons of CNS cells. Oligodendrocyte development continues from before birth into adulthood, thus these cells may be particularly vulnerable to damage from toxic chemicals.

The researchers analyzed the effects of 1823 chemicals on mouse oligodendrocyte development in cell cultures. They identified 292 chemicals that cause oligodendrocytes to die and 47 that inhibit oligodendrocyte generation. These chemicals belonged to two different classes.

They found that quaternary compounds were potently and selectively cytotoxic to developing oligodendrocytes and that organophosphate flame retardants prematurely arrested oligodendrocyte maturation. These effects were confirmed in mice and cultured human oligodendrocytes.

In addition, an analysis of epidemiologic data from the National Health and Nutrition Examination Survey (2013-2018) showed that one flame retardant metabolite, bis(1,3-dichloro-2-propy) phosphate (BDCIPP), was present in nearly all urine samples of children aged 3-11 years who were examined (1753 out of 1763 children).

After adjustment for multiple confounding factors, results showed that compared with children with urinary BDCIPP concentration in the lowest quartile, those with concentrations in the highest quartile were twice as likely to require special education (adjusted odds ratio [aOR], 2.0; 95% CI, 1.0-3.8) and were six times as likely to have gross motor dysfunction (aOR, 6.0; 95% CI, 1.7-21.9).

Children with urinary BDCIPP concentration within the third quartile also had significantly increased odds of motor dysfunction (aOR, 4.2; 95% CI, 1.1-16.2). 

“These results suggest that the identified chemicals are potentially hazardous to human health. However, we want to be clear that more studies are needed to make definitive connections between chemical exposure and human disease,” said Dr. Tesar.

“Future studies will need to deepen our understanding of the duration and timing of exposure required to initiate or exacerbate disease. This information is needed before specific recommendations, such as behavioral interventions, can be made to reduce exposure. Some of these chemicals have useful roles in our homes, but we need to consider how they’re being used and what level of exposure might be considered safe,” Dr. Tesar said. 

In his view, the results “provide a starting point to understand what exposure levels to these chemicals might be putting ourselves or kids at risk for toxicity.”
 

Too Soon to Tell

Commenting for this news organization, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, who was not involved in the study, echoed the need for more research. 

“The biological mechanisms uncovered provide plausible pathways by which these chemicals could potentially impact human brain development related to oligodendrocytes and myelination. Oligodendrocytes play a critical role in plastic neurological processes throughout life, not just early neurodevelopment. So, disrupting their maturation and function theoretically could contribute to neurodevelopmental disorders as well as adult conditions like multiple sclerosis,” Dr. Lakhan said. 

“This study alone shouldn’t sound neurotoxicant alarms yet. We’ve seen many past chemical scares like saccharin and phthalates fizzle despite alarming lab results when real-world human brain impacts failed to materialize,” Dr. Lakhan cautioned. 

“Far more rigorous research directly linking household chemical exposures to cognitive deficits in people is still needed before drawing firm conclusions or prompting overreactions from the general public. Policymakers will eventually need to weigh potential risks vs benefits, but no definitive human health threat has currently been established,” Dr. Lakhan said. 

Sarah Evans, PhD, MPH, assistant professor in the Department of Environmental Medicine and Public Health, Icahn School of Medicine at Mount Sinai in New York, also emphasized the need for further study.

“Given that most of the experiments in this study were conducted in isolated cells and a mouse model, further research is needed to determine whether exposure to these chemicals at levels experienced by the general population during critical windows of development impairs myelination and leads to adverse health outcomes like learning and behavior problems in humans,” said Dr. Evans, who was involved in the study.

“The authors’ finding of an association between higher urinary levels of the organophosphate flame-retardant metabolite BDCIPP and gross motor problems or need for special education in children aged 3-11 years in the CDC National Health and Nutrition Examination Survey strengthens their laboratory findings and warrants further investigation,” Dr. Evans added. 

The research was supported by grants from the National Institutes of Health, National Multiple Sclerosis Society, Howard Hughes Medical Institute and New York Stem Cell Foundation, and philanthropic support by sTF5 Care and the Long, Walter, Peterson, Goodman, and Geller families. Dr. Tesar, Dr. Lakhan, and Dr. Evans report no relevant disclosures.
