The positive results from the SELECT trial for the glucagon-like peptide-1 receptor agonists (GLP-1 RAs) were hailed as ushering in a “new era for patients with obesity.” In the trial of overweight and obese patients with cardiovascular disease (CVD), but no diabetes, semaglutide showed meaningful reductions in cardiovascular death, myocardial infarction, and stroke compared with placebo.

“I definitely see increasing adoption of GLP-1 RAs by cardiologists and expect the number to increase now that the data support its use in secondary prevention,” said Nicole L. Lohr, MD, PhD, chair of the American College of Cardiology (ACC) Board of Governors, and Mary G. Waters, chair of cardiovascular medicine at UAB, Birmingham.

But many cardiologists are more hesitant. “I think there’s going to be an increasing urgency for cardiologists to start prescribing these drugs, but I don’t think the comfort to do so is that widespread at this point,” said American Heart Association (AHA) volunteer Chiadi E. Ndumele, MD, PhD, an associate professor at Johns Hopkins Medicine in Baltimore and chair of the AHA’s recent presidential advisory on cardiovascular-kidney-metabolic health.

“Weight loss hasn’t been a central focus in our practice until recently, with the advent of these more powerful agents. There’s a need for more education around not only the use of these agents, but also around initiating weight loss discussions in a nonjudgmental way that reflects the complexity of obesity as a condition with multifactorial causes.”

The process will take time and may be similar to what happened with statins, he suggests. “Statins started in the endocrinology space, but as their cardiovascular benefits became more clear, they were increasingly adopted by cardiologists, primary care physicians, and others.”

Eugene Yang, MD, chair of the ACC Prevention of CVD Council and codirector of UW Medicine’s Cardiovascular Wellness and Prevention Program in Seattle, agrees that GLP-1 uptake by cardiologists will likely be slow. “It’s a bit premature to start prescribing right away,” he said. “Semaglutide hasn’t been approved for secondary prevention at this point, and until it’s approved specifically for that indication, I don’t think many cardiologists will prescribe it.”
 

Side Effects ‘Concerning’

Beyond the requisite approval, Dr. Yang is concerned about side effects such as gastroparesis, severe nausea, and vomiting. “I’m not sure cardiologists are going to feel comfortable helping patients deal with these effects.”

Because GLP-1 RAs are already being used widely in primary care, he says, “I personally would work in collaboration with either my primary care colleagues or with endocrinologists.”

Ambarish Pandey, MD, an associate professor of internal medicine (cardiology) and medical director of the heart failure with preserved ejection fraction (HFpEF) program at UT Southwestern Medical Center, Dallas, is already prescribing semaglutide to patients with HFpEF and obesity. “In terms of side effects, I just tell patients what to expect,” he says.

Dr. Pandey prepares patients for appetite reduction, early satiety and fullness, abdominal discomfort, nausea, and other gastrointestinal symptoms. “Then I start low and slowly titrate to achieve enough weight loss. If they’re having adverse effects on a higher dose, I use a lower dose.”

The approach is working well for most patients, he says. “Obviously there’s some initial getting used to the drug, but once that has happened, patients like it because they see improvements in their exercise capacity and quality of life.”

But GLP-1 RAs are also associated with increased heart rate, which “is never good news,” notes Howard Weintraub, MD, a professor of medicine at NYU Grossman School of Medicine in New York City and clinical director of the NYU Center for the Prevention of Cardiovascular Disease. At least some of the elevation may be masked by beta-blocker use, he suggests. “The mechanism is not well elucidated, but it is something we’re going to need to keep an eye on, because we don’t want to get ambushed.”
 

Cost, Access ‘Significant Barriers’

All the cardiologists this news organization spoke with agreed that cost and access will be significant barriers to widespread prescribing, at least for now.

“Prescribing for individuals at very high cardiovascular risk will probably give a reasonable amount of bang for your buck. But individuals with more adverse social determinants of health, who are more likely to have challenges with obesity and related complications, are also least likely to be able to pay the exorbitant costs out of pocket. So, this is also an important health equity issue,” Dr. Ndumele says.

Furthermore, he adds, where GLP-1 RAs will fit for those with a lower absolute CVD risk “is still a clear question.”

“Access comes two ways,” Dr. Weintraub says. “One is the supply, which continues to be an issue. You can’t sell the drug if you don’t have it.”

The other access route is the insurance companies. “Will they throw down a gauntlet and make cardiologists prove that a patient failed other obesity drugs before they can prescribe a GLP-1 RA? Some of the old obesity drugs are not only unpleasant to use, but they’re ineffective and may have bad cardiac signals.”

If the new drugs are approved for secondary prevention, patients will want them and doctors will want them, he says. The demand will be “huge,” and it’s not clear how it will be handled.

Dr. Pandey agrees that getting the drug without “good insurance” to cover the cost is a big challenge. “ As more of these drugs become available, hopefully the cost will come down, and hopefully access will grow as companies are able to scale up production.”
 

Add-On or Substitute?

Anticipating approval, Dr. Yang says it’s not yet clear where the GLP-1 RAs stand among the various available cardiovascular therapies.

“Based on the results of SELECT, one could argue that maybe it’s more important to get the weight down and reduce blood pressure versus adding another cholesterol-lowering medication, for example, especially if a patient is already on a statin and ezetimibe. But maybe their low-density lipoprotein cholesterol is not exactly below the threshold of the current guideline. And maybe they’re overweight or prediabetic, and they can lose 10% or 15% of their body weight with a GLP-1 RA. You may have to pick and choose.”

That said, he adds, “Who’s going to be able to afford all of this? Some patients would be taking a PCSK9 inhibitor, bempedoic acid because their lipids are not optimized, then a GLP-1 receptor. Right there, we’re talking about at least $2000 a month for those three medications. That’s not feasible.”

“This is one of the things I’ve worried about, given all the drugs some of our patients are on,” Dr. Weintraub says. “The data on cholesterol-lowering drugs are so monumental, it’s hard to say you can do without it. The same is true of blood pressure-lowering medication. So to my mind, a GLP-1 RA is going to have to be an add-on.”

“The only good news is that unlike in the heart failure arena, patients are not paying for other drugs on top of it,” he says. “Statins, ACE inhibitors, ARBs, and beta-blockers are all generic; they’re not going to leave a huge hole in the patient’s pocket when the donut hole [Medicare payment gap] comes around. So in this case, if the GLP-1 RAs get included, which I hope they will, the added cost may not be that horrible.”
 

What About Lifestyle Changes?

Everyone agreed that the drugs are not a substitute for lifestyle changes.

“I have seen many patients who take these medications reach plateaus, and when discontinued, gain back the weight. I counsel patients to view the medication as an aid and not necessarily a magic wand,” Dr. Lohr says.

Dr. Ndumele agrees. “I advocate a lifestyle-first approach,” he says. “I imagine there will be busy clinicians who will prescribe medications as a first line, but that’s not going to be our most effective approach.”

The major challenge to such an approach, he says, is that lifestyle support has to be ongoing. “It’s not the kind of thing that just happens in a yearly doctor’s visit appointment, and it’s been under-supported in most coverage and reimbursement strategies.”

In his clinical practice, which includes ongoing support for lifestyle changes, Dr. Ndumele is seeing far greater weight loss than was shown in SELECT. “I think there’s a real benefit to having the two approaches come together,” he says.

Dr. Yang also favors an emphasis on lifestyle. “The success rate of a lifestyle approach may be low, but that doesn’t change the importance of it. We need to figure out better ways to do it.” Leveraging technology is one way, he suggests, such as cellphone reminders to walk more or alerts to tell you when to sleep.

“I also encourage patients to monitor their own blood pressure, and they do.” Dr. Yang acknowledges that his patient population is highly educated with access to resources to purchase the technological devices. However, he adds, “if the clinician is negative, and doesn’t really believe these interventions will work, the patient can sense that, and then they won’t work.” It’s up to the clinician to promote the importance of these lifestyle changes in order to be successful. Is it discouraging at times? Yes. But don’t let the patient know.”

Dr. Pandey approaches the issue differently. “Our healthcare system is such that patients don’t get to see us that often, so I think we should start the lifestyle intervention, but also start the medication at the same time, in parallel, because we don’t have time to take a stepwise approach.”

“Lifestyle interventions are better received if patients see positive improvements, and the medication actually induces a positive improvement,” he says. He is concerned that if a lifestyle first approach doesn’t work “that can affect the willingness to try future therapies. And we don’t want to lose like 6 or 8 months just trying lifestyle when they could have benefited from the weight-loss medication, as well.”

Dr. Lohr, Dr. Ndumele, and Dr. Yang report no conflicts of interest. Dr. Weintraub reports being an investigator in the SELECT trial and a consultant for NovoNordisk. Dr. Pandey reports receiving research support from the National Institutes of Health; grant funding from Applied Therapeutics and Gilead Sciences; honoraria outside of the present study as an advisor/consultant for Tricog Health Inc, Lilly USA, Rivus, Cytokinetics, Roche Diagnostics, Axon therapies, Medtronic, Edwards Lifesciences, Science 37 Novo Nordisk, Bayer, Merck, Sarfez Pharmaceuticals, Emmi Solutions; and has received nonfinancial support from Pfizer and Merck; and serving as a consultant for Palomarin Inc. with stocks compensation.

UnitedHealth Group, the parent company of the nation’s largest private insurer, UnitedHealthcare (UHC), is now affiliated with or employs approximately 10% of the US physician workforce, raising anti-trust and noncompete concerns as more payers and private equity firms pursue medical practice acquisitions.

The company added 20,000 physicians in the last year alone, including a previously physician-owned multispecialty group practice of 400 doctors in New York. They join the growing web of doctors — about 90,000 of the 950,000 active US physicians — working for the UnitedHealth Group subsidiary, Optum Health, providing primary, specialty, urgent, and surgical care. Amar Desai, MD, chief executive officer of Optum Health, shared the updated workforce numbers during the health care conglomerate’s annual investor conference.

Health care mergers and consolidations have become more common as physician groups struggle to stay afloat amid dwindling payer reimbursements. Although private equity and health systems often acquire practices, payers like UHC are increasingly doing so as part of their model to advance value-based care. 

Yashaswini Singh, PhD, health care economist and assistant professor of health services, policy, and practice at Brown University, says such moves mirror the broader trend in corporate consolidation of physician practices. She said in an interview that the integrated models could possibly enhance care coordination and improve outcomes, but the impact of payer-led consolidation has not been extensively studied. 

Meanwhile, evidence considering private equity ownership is just emerging. In a 2022 study published in JAMA Health Forum, with Dr. Singh as lead author, findings showed that private equity involvement increased healthcare spending through higher prices and utilization. 

Consolidation can also raise anti-trust concerns. “If payers incentivize referral patterns of their employed physicians to favor other physicians employed by the payer, it can reduce competition by restricting consumer choice,” said Dr. Singh. 

A potential merger between Cigna and Humana that could happen by the end of the year will likely face intense scrutiny as it would create a company that rivals the size of UnitedHealth Group or CVS Health. If it goes through, the duo could streamline its insurance offerings and leverage each other’s care delivery platforms, clinics, and provider workforce. 

The Biden Administration has sought to strengthen anti-trust statutes to prevent industry monopolies and consumer harm, and the US Department of Justice and Federal Trade Commission have proposed new merger guidelines that have yet to be finalized. 

According to Dr. Singh, some of Optum’s medical practice purchases may bypass anti-trust statutes since most prospective mergers and acquisitions are reviewed only if they exceed a specific value ($101 million for 2023). Limited transparency in ownership structures further complicates matters. Plus, Dr. Singh said instances where physicians are hired instead of acquired through mergers would not be subject to current anti-trust laws. 

The ‘corporatization’ of health care is not good for patients or physicians, said Robert McNamara, MD, chief medical officer of the American Academy of Emergency Medicine Physician Group and cofounder of Take Medicine Back, a physician group advocating to remove corporate interests from health care. 

“If you ask a physician what causes them the most moral conflict, they’ll tell you it’s the insurance companies denying something they want to do for their patients,” he said. “To have the doctors now working for the insurance industry conflicts with a physician’s duty to put the patient first.” 

Dr. McNamara, chair of emergency medicine at Temple University’s Katz School of Medicine, said in an interview that more than half the states in the United States have laws or court rulings that support protecting physician autonomy from corporate interests. Still, he hopes a federal prohibition on private equity’s involvement in healthcare can soon gain traction. In November, Take Medicine Back raised a resolution at the American Medical Association’s interim House of Delegates meeting, which he said was subsequently referred to a committee. 

Emergency medicine was among the first specialties to succumb to private equity firms, but Dr. McNamara said that all types of health care providers and entities — from cardiology and urology to addiction treatment centers and nursing homes — are being swallowed up by larger organizations, including payers. 

UHC was named in a class action suit recently for allegedly shirking doctors’ orders and relying on a flawed algorithm to determine the length of skilled nursing facility stays for Medicare Advantage policyholders. 

At the investor meeting, Dr. Desai reiterated Optum’s desire to continue expanding care delivery options, especially in its pharmacy and behavioral health business lines, and focus on adopting value-based care. He credited the rapid growth to developing strong relationships with providers and standardizing technology and clinical systems.

UnitedHealth Group, the parent company of the nation’s largest private insurer, UnitedHealthcare (UHC), is now affiliated with or employs approximately 10% of the US physician workforce, raising anti-trust and noncompete concerns as more payers and private equity firms pursue medical practice acquisitions.

The company added 20,000 physicians in the last year alone, including a previously physician-owned multispecialty group practice of 400 doctors in New York. They join the growing web of doctors — about 90,000 of the 950,000 active US physicians — working for the UnitedHealth Group subsidiary, Optum Health, providing primary, specialty, urgent, and surgical care. Amar Desai, MD, chief executive officer of Optum Health, shared the updated workforce numbers during the health care conglomerate’s annual investor conference.

Health care mergers and consolidations have become more common as physician groups struggle to stay afloat amid dwindling payer reimbursements. Although private equity and health systems often acquire practices, payers like UHC are increasingly doing so as part of their model to advance value-based care. 

Yashaswini Singh, PhD, health care economist and assistant professor of health services, policy, and practice at Brown University, says such moves mirror the broader trend in corporate consolidation of physician practices. She said in an interview that the integrated models could possibly enhance care coordination and improve outcomes, but the impact of payer-led consolidation has not been extensively studied. 

Meanwhile, evidence considering private equity ownership is just emerging. In a 2022 study published in JAMA Health Forum, with Dr. Singh as lead author, findings showed that private equity involvement increased healthcare spending through higher prices and utilization. 

Consolidation can also raise anti-trust concerns. “If payers incentivize referral patterns of their employed physicians to favor other physicians employed by the payer, it can reduce competition by restricting consumer choice,” said Dr. Singh. 

A potential merger between Cigna and Humana that could happen by the end of the year will likely face intense scrutiny as it would create a company that rivals the size of UnitedHealth Group or CVS Health. If it goes through, the duo could streamline its insurance offerings and leverage each other’s care delivery platforms, clinics, and provider workforce. 

The Biden Administration has sought to strengthen anti-trust statutes to prevent industry monopolies and consumer harm, and the US Department of Justice and Federal Trade Commission have proposed new merger guidelines that have yet to be finalized. 

According to Dr. Singh, some of Optum’s medical practice purchases may bypass anti-trust statutes since most prospective mergers and acquisitions are reviewed only if they exceed a specific value ($101 million for 2023). Limited transparency in ownership structures further complicates matters. Plus, Dr. Singh said instances where physicians are hired instead of acquired through mergers would not be subject to current anti-trust laws.

TOPLINE

Babies born to mothers living in disadvantaged neighborhoods have a higher risk of being diagnosed with autism spectrum disorder (ASD), but only if they are White, a population-based prospective cohort study shows. 

METHODOLOGY

• Investigators analyzed data from a large cohort of singleton children with insurance born in Kaiser Permanente Southern California hospitals between 2001 and 2014.
• They ascertained ASD diagnosis, maternal race and ethnicity, and maternal address at time of birth.
• Neighborhood disadvantage was determined by the percentage of families in the mother’s neighborhood considered to be living in poverty, unemployed, have female-headed households with children, using public assistance, less than a high school education, among other variables.

TAKEAWAY

• Among 318,300 mothers who delivered babies during the study period, 6350 children were diagnosed with ASD during follow-up, and median age at diagnosis was 3.5 years.
• Greater neighborhood disadvantage at birth was associated with a higher likelihood of ASD diagnosis (adjusted hazard ratio [aHR], 1.07; 95% CI, 1.02-1.11)
• ASD diagnoses were more likely among children of mothers who were Black (aHR, 1.13; 95% CI, 1.02-1.25), Asian/Pacific Islander (aHR, 1.11; 95% CI, 1.02-1.20), or Hispanic (aHR, 1.07; 95% CI, 1.00-1.15), even after the researchers controlled for neighborhood.
• While odds of an ASD diagnosis were higher among children from minority racial and ethnic groups, neighborhood disadvantage was significantly associated with ASD diagnosis only for children of White mothers (aHR, 1.17; 95% CI, 1.09-1.26).

IN PRACTICE

Investigators noted that they could only speculate about the factors driving the association between neighborhood disadvantage and a stronger risk for ASD diagnosis in children of White mothers. “They may be due to systemic racism, discrimination, and their impact on maternal health during pregnancy,” they wrote.

SOURCE

Xin Yu, MS, and Daniel Hackman, PhD, of the University of Southern California Los Angeles, led the study, which was published online November 15 in JAMA Psychiatry. 

LIMITATIONS

The research was limited by a lack of information on fathers and variables such as incomes, which may have confounded the findings. The authors also acknowledged that the study should be replicated in other health service settings. 

DISCLOSURES

The study was funded by the National Institutes on Environmental Health Sciences, the National Institutes of Health (NIH), and the Environmental Protection Agency. Dr. Hackman reported receiving grant funding from NIH during the conduct of the study. Other disclosures are available in the original study.

A study investigating the effectiveness of a pilot program to educate barbers about pseudofolliculitis barbae (PFB) found that the barbers significantly improved their knowledge about the causes, prevention, and treatment of the condition after the educational intervention.

The results were published in a research letter in JAMA Dermatology. “Educating barbers on dermatologic conditions that disproportionately affect Black males and establishing referral services between barbers and dermatologists could serve as plausible interventions,” the authors wrote.

PFB — or “razor bumps” in layman’s terms — is a chronic, inflammatory follicular disorder, which can occur in any racial group, but primarily affects Black men, noted the corresponding author of the study, Xavier Rice, MD, a dermatology resident at Washington University in Saint Louis, Missouri. PFB manifests as bumps and pustules or nodules along the beard line and are painful, he said in an interview. “They tend to leave scars once they resolve,” and impair the ability to shave, he noted.

In some communities, Black men may see their barbers more often than primary care doctors or dermatologists, “so if you equip the barbers with the knowledge to recognize the disease, make recommendations on how to prevent and to treat, and also form some allyship with barbers and dermatologists, then we can get referrals for people, especially the ones with severe disease,” he said. A lot of the barbers in the study said that “they didn’t receive much education on how to properly address it [PFB] and they had a lot of miseducation about what actually caused it,” added Dr. Rice, who was a medical student at the University of Texas Medical Branch, Galveston, when the study was conducted.

Study involved 40 barbers

For the study, Dr. Rice and his coauthors surveyed 40 barbers in the Houston, Texas, area; 39 were Black and one was Hispanic; 75% were men and 25% were women. Most (90%) said that at least 60% of their clients were Black. Between January and April 2022, the barbers received questionnaires before and after participating in a session that involved a review of a comprehensive educational brochure with information on the recognition, cause, prevention, and treatment of PFB, which they then kept for reference and to provide to clients as needed. “Common myths and nuanced home remedies from barber experience were also addressed,” the authors wrote.

No more than 2 weeks after the information session, each barber completed a posttest questionnaire.

Based on their responses to pretest questions, 39 of the 40 barbers understood that Black men were the group most impacted by PFB and that a person with severe PFB should see a physician. In the pretest survey, 12 barbers (30%) correctly recognized a photo of PFB, which increased to 39 (97.5%) in the posttest survey. In the pretest survey, two barbers (5%) identified laser hair removal as the most effective treatment for PFB, compared with 37 (92.5%) in the posttest survey.

Overall, the mean percentage of correct scores out of 20 questions was 54.8% in the pretest survey, increasing to 91% in the posttest survey (P <.001).

Limitations of the studies included heterogeneity in the survey response options that potentially could have introduced bias, the authors wrote. Another was that since there is a lack of evidence for ideal treatment strategies for PFB, there may have been some uncertainty among the correct answers for the survey that might have contributed to variability in responses. “Further research and implementation of these interventions are needed in efforts to improve health outcomes,” they added.

“Barbers can serve as allies in referral services,” Dr. Rice said in the interview. “They can be the first line for a number of diseases that are related to hair.”

Part of his role as a dermatologist, he added, includes going into a community with “boots on the ground” and talking to people who will see these patients “because access to care, presentation to big hospital systems can be challenging.”

Dr. Rice and the other study authors had no not report any financial disclosures.

The increased risk of vitiligo found in recipients of stem cell and solid organ transplants, especially those who develop graft-versus-host disease (GVHD), requires careful monitoring, according to authors of a study published online in JAMA Dermatology December 13.

In the cohort study, the greatest risk occurred with hematopoietic stem cell transplants (HSCTs) and in cases involving GVHD. Kidney and liver transplants carried slight increases in risk.

“The findings suggest that early detection and management of vitiligo lesions can be improved by estimating the likelihood of its development in transplant recipients and implementing a multidisciplinary approach for monitoring,” wrote the authors, from the departments of dermatology and biostatistics, at the Catholic University of Korea, Seoul.

Using claims data from South Korea’s National Health Insurance Service database, the investigators compared vitiligo incidence among 23,829 patients who had undergone solid organ transplantation (SOT) or HSCT between 2010 and 2017 versus that of 119,145 age- and sex-matched controls. At a mean observation time of 4.79 years in the transplant group (and 5.12 years for controls), the adjusted hazard ratio (AHR) for vitiligo among patients who had undergone any transplant was 1.73. AHRs for HSCT, liver transplants, and kidney transplants were 12.69, 1.63, and 1.50, respectively.

Patients who had undergone allogeneic HSCT (AHR, 14.43) or autologous transplants (AHR, 5.71), as well as those with and without GVHD (24.09 and 8.21, respectively) had significantly higher vitiligo risk than the control group.

Among those with GVHD, HSCT recipients (AHR, 16.42) and those with allogeneic grafts (AHR, 16.81) had a higher vitiligo risk than that of control patients.

In a subgroup that included 10,355 transplant recipients who underwent posttransplant health checkups, investigators found the highest vitiligo risk — AHR, 25.09 versus controls — among HSCT recipients with comorbid GVHD. However, patients who underwent SOT, autologous HSCT, or HSCT without GVHD showed no increased vitiligo risk in this analysis. “The results of health checkup data analysis may differ from the initial analysis due to additional adjustments for lifestyle factors and inclusion of only patients who underwent a health checkup,” the authors wrote.

Asked to comment on the results, George Han, MD, PhD, who was not involved with the study, told this news organization, “this is an interesting paper where the primary difference from previous studies is the new association between GVHD in hematopoietic stem cell transplant recipients and vitiligo.” Prior research had shown higher rates of vitiligo in HSCT recipients without making the GVHD distinction. Dr. Han is associate professor of dermatology in the Hofstra/Northwell Department of Dermatology, Hyde Park, New York.

Although GVHD may not be top-of-mind for dermatologists in daily practice, he said, the study enhances their understanding of vitiligo risk in HSCT recipients. “In some ways,” Dr. Han added, “the association makes sense, as the activated T cells from the graft attacking the skin in the HSCT recipient follow many of the mechanisms of vitiligo, including upregulating interferon gamma and the CXCR3/CXCL10 axis.”

Presently, he said, dermatologists worry more about solid organ recipients than about HSCT recipients because the long-term immunosuppression required by SOT increases the risk of squamous cell carcinoma (SCC). “However, the risk of skin cancers also seems to be elevated in HSCT recipients, and in this case the basal cell carcinoma (BCC):SCC ratio is not necessarily reversed as we see in solid organ transplant recipients. So the mechanisms are a bit less clear. Interestingly, acute and chronic GVHD have both been associated with increased risks of BCC and SCC/BCC, respectively.”

Overall, Dr. Han said, any transplant recipient should undergo yearly skin checks not only for skin cancers, but also for other skin conditions such as vitiligo. “It would be nice to see this codified into official guidelines, which can vary considerably but are overall more consistent in solid organ transplant recipients than in HSCT recipients. No such guidelines seem to be available for HSCTs.”

The study was funded by the Basic Research in Science & Engineering program through the National Research Foundation of Korea, which is funded by the country’s Ministry of Education. The study authors had no disclosures. Dr. Han reports no relevant financial interests.

The increased risk of vitiligo found in recipients of stem cell and solid organ transplants, especially those who develop graft-versus-host disease (GVHD), requires careful monitoring, according to authors of a study published online in JAMA Dermatology December 13.

In the cohort study, the greatest risk occurred with hematopoietic stem cell transplants (HSCTs) and in cases involving GVHD. Kidney and liver transplants carried slight increases in risk.

“The findings suggest that early detection and management of vitiligo lesions can be improved by estimating the likelihood of its development in transplant recipients and implementing a multidisciplinary approach for monitoring,” wrote the authors, from the departments of dermatology and biostatistics, at the Catholic University of Korea, Seoul.

Using claims data from South Korea’s National Health Insurance Service database, the investigators compared vitiligo incidence among 23,829 patients who had undergone solid organ transplantation (SOT) or HSCT between 2010 and 2017 versus that of 119,145 age- and sex-matched controls. At a mean observation time of 4.79 years in the transplant group (and 5.12 years for controls), the adjusted hazard ratio (AHR) for vitiligo among patients who had undergone any transplant was 1.73. AHRs for HSCT, liver transplants, and kidney transplants were 12.69, 1.63, and 1.50, respectively.

Patients who had undergone allogeneic HSCT (AHR, 14.43) or autologous transplants (AHR, 5.71), as well as those with and without GVHD (24.09 and 8.21, respectively) had significantly higher vitiligo risk than the control group.

Among those with GVHD, HSCT recipients (AHR, 16.42) and those with allogeneic grafts (AHR, 16.81) had a higher vitiligo risk than that of control patients.

In a subgroup that included 10,355 transplant recipients who underwent posttransplant health checkups, investigators found the highest vitiligo risk — AHR, 25.09 versus controls — among HSCT recipients with comorbid GVHD. However, patients who underwent SOT, autologous HSCT, or HSCT without GVHD showed no increased vitiligo risk in this analysis. “The results of health checkup data analysis may differ from the initial analysis due to additional adjustments for lifestyle factors and inclusion of only patients who underwent a health checkup,” the authors wrote.

Asked to comment on the results, George Han, MD, PhD, who was not involved with the study, told this news organization, “this is an interesting paper where the primary difference from previous studies is the new association between GVHD in hematopoietic stem cell transplant recipients and vitiligo.” Prior research had shown higher rates of vitiligo in HSCT recipients without making the GVHD distinction. Dr. Han is associate professor of dermatology in the Hofstra/Northwell Department of Dermatology, Hyde Park, New York.

Although GVHD may not be top-of-mind for dermatologists in daily practice, he said, the study enhances their understanding of vitiligo risk in HSCT recipients. “In some ways,” Dr. Han added, “the association makes sense, as the activated T cells from the graft attacking the skin in the HSCT recipient follow many of the mechanisms of vitiligo, including upregulating interferon gamma and the CXCR3/CXCL10 axis.”

Presently, he said, dermatologists worry more about solid organ recipients than about HSCT recipients because the long-term immunosuppression required by SOT increases the risk of squamous cell carcinoma (SCC). “However, the risk of skin cancers also seems to be elevated in HSCT recipients, and in this case the basal cell carcinoma (BCC):SCC ratio is not necessarily reversed as we see in solid organ transplant recipients. So the mechanisms are a bit less clear. Interestingly, acute and chronic GVHD have both been associated with increased risks of BCC and SCC/BCC, respectively.”

Overall, Dr. Han said, any transplant recipient should undergo yearly skin checks not only for skin cancers, but also for other skin conditions such as vitiligo. “It would be nice to see this codified into official guidelines, which can vary considerably but are overall more consistent in solid organ transplant recipients than in HSCT recipients.

Children with obesity issues should undergo “comprehensive, intensive behavioral interventions,” including supervised physical activity sessions for up to a year, a federal task force said. 

The U.S. Preventive Services Task Force — a team of independent, volunteer experts in disease prevention who guide doctors’ decisions and influence insurance coverage — issued a draft recommendation statement outlining the interventions that should be taken when a child or teen has a high body mass index. 

Nearly 20% of children between 2 and 19 years old have what are considered high BMIs, according to Centers for Disease Control and Prevention data. While adults who have a BMI of 30 or higher are considered to have obesity, childhood obesity is determined if a child is at or above the 95th percentile of others their age and gender. 

Given the prevalence of the issue, the task force recommends behavioral interventions that include at least 26 hours of supervised physical activity sessions for up to a year. This differs from the task force’s previous recommendations on the topic, which emphasized the importance of screening for high BMIs rather than describing the right ways to intervene.

Some of the most effective interventions are targeted at both parents and their children, whether that be together, separately, or a combination of the two. Additionally, the task force recommends that children attend group sessions about healthy eating habits, how to read food labels, and exercise techniques. Ideally, these would be led and guided by people of various professional backgrounds like pediatricians, physical therapists, dietitians, psychologists, and social workers. Other medical organizations, namely the American Academy of Pediatrics, have recommended medication for some children with obesity; the task force, however, takes a more conservative approach. They noted that although the body of evidence shows weight loss medications and surgery are effective for many, there isn’t enough research to lean on regarding the use of these interventions in children, especially in the long term. 

“There are proven ways that clinicians can help the many children and teens who have a high BMI to manage their weight and stay healthy,” said Katrina Donahue, MD, MPH, a member of the task force and professor of family medicine at the University of North Carolina at Chapel Hill. “Intensive behavioral interventions are effective in helping children achieve a healthy weight while improving quality of life.”

The guidelines are still in the draft stage and are available for public comment until Jan. 16, 2024.

TOPLINE:

Among adolescent pregnancies in the United States, the prevalence of e-cigarette use during the third trimester increased from 0.8% in 2016 to 4.1% in 2021, according to research published online on December 13 in JAMA Network Open. 

METHODOLOGY:

• Researchers analyzed data from the 2016-2021 Pregnancy Risk Assessment Monitoring System.
• They focused on 10,428 adolescents aged 10-19 years who had had a singleton birth and provided information about their use of e-cigarettes or cigarettes.

TAKEAWAY:

• Whereas the researchers found a roughly fivefold increase in the exclusive use of e-cigarettes, the percentage of patients using only cigarettes decreased from 9.2% in 2017 to 3.2% in 2021.
• The percentage of patients who both vaped and smoked fluctuated between 0.6% and 1.6%.
• The rate of small-for-gestational-age (SGA) births for adolescents who did not smoke or vape (12.9%) did not differ significantly from that among adolescents who exclusively used e-cigarettes (16.8%) or those who used both cigarettes and e-cigarettes (17.6%).
• The researchers found use of cigarettes only was associated with a significantly higher rate of SGA births: 24.6%.

IN PRACTICE:

“Exclusive e-cigarette use and dual use of cigarettes and e-cigarettes did not seem to be statistically significantly associated with SGA birth in our analysis, but this finding should be interpreted with caution given the low prevalence of use and the limited sample size,” the study authors wrote.

SOURCE:

Xiaozhong Wen, MD, PhD, with the Jacobs School of Medicine and Biomedical Sciences at the State University of New York at Buffalo, was the corresponding author of the study. 

LIMITATIONS:

Participants may have underreported their use of e-cigarettes and cigarettes because of fears of social stigma. The researchers lacked information about vaping in the first and second trimesters, exposure to secondhand smoke, cannabis use, and diet. 

DISCLOSURES:

The research was supported by the National Institute on Drug Abuse; the Food and Drug Administration Center for Tobacco Products; the National Heart, Lung, and Blood Institute; and the American Heart Association. A study coauthor has received grants from Pfizer and personal fees from Johnson & Johnson, the World Health Organization, and the Campaign for Tobacco-Free Kids.

A digital stethoscope that uses artificial intelligence (AI) is better at detecting heart murmurs associated with clinically significant valvular heart disease (VHD) than is a primary care physician (PCP) using a traditional stethoscope, a new study shows.

The results suggest collecting relevant sounds through a stethoscope (auscultation) using AI-powered technology is an important primary care tool to detect VHD, study author Moshe A. Rancier, MD, medical director, Massachusetts General Brigham Community Physicians, Lawrence, Massachusetts, said in an interview.

“Incorporating this AI-assisted device into the primary care exam will help identify patients at risk for VHD earlier and eventually decrease costs in our healthcare system,” he said, because timely detection could avoid emergency room visits and surgeries.

The findings were presented at the annual scientific sessions of the American Heart Association.
 

VHD Common

Clinically significant VHD, indicating structural damage to heart valves, affects 1 in 10 adults older than 65 years. Patients may be asymptomatic or present to their PCP with an unspecific symptom like fatigue or malaise.

If VHD is undiagnosed and left untreated, patients could develop more severe symptoms, even be at risk for death, and their quality of life is significantly affected, said Dr. Rancier.

Cardiac auscultation, the current point-of-care clinical standard, has relatively low sensitivity for detecting VHD, leaving most patients undiagnosed.

The deep learning–based AI tool uses sound data to detect cardiac murmurs associated with clinically significant VHD. The device used in the study (Eko; Eko Health) is approved by the US Food and Drug Administration and is on the market.

The tool identifies background sounds that might affect the evaluation. “If there’s any noise or breath sounds, it tells me this is not a good heart sound, and asks me to record again,” said Dr. Rancier.

A doctor using the AI-assisted stethoscope carries out the auscultation exam with the sound data captured by a smartphone or tablet and sent to the AI server. “I get an answer in a second as to if there’s a murmur or not,” said Dr. Rancier.

Not only that, but the tool can determine if it’s a systolic or diastolic murmur, he added.
 

Real-World Population

The study enrolled a “real-world” population of 368 patients, median age 70 years, 61% female, 70% White, and 18% Hispanic without a prior VHD diagnosis or history of murmur, from three primary care clinics in Queens, New York, and Lawrence and Haverhill, Massachusetts. 

About 79% of the cohort had hypertension, 68% had dyslipidemia, and 38% had diabetes, “which aligns with the population in the US,” said Dr. Rancier.

Each study participant had a regular exam carried out by Dr. Rancier using a traditional stethoscope to detect murmurs and an exam by a technician with a digital stethoscope that collected phonocardiogram (PCG) data for analysis by AI.

In addition, each patient received an echocardiogram 1-2 weeks later to confirm whether clinically significant VHD was present. An expert panel of cardiologists also reviewed the patient’s PCG recordings to confirm the presence of audible murmurs.

Dr. Rancier and the expert panel were blinded to AI and echocardiogram results.

Researchers calculated performance metrics for both PCP auscultation and the AI in detecting audible VHD.

The study showed that AI improved sensitivity to detect audible VHD by over twofold compared with PCP auscultation (94.1% vs 41.2%), with limited impact on specificity (84.5% vs 95.5%).

Dr. Rancier stressed the importance of sensitivity because clinicians tend to under-detect murmurs. “You don’t want to miss those patients because the consequences of undiagnosed VHD are dire.”

The AI tool identified 22 patients with moderate or greater VHD who were previously undiagnosed, whereas PCPs identified eight previously undiagnosed patients with VHD.

Dr. Rancier sees this tool being used beyond primary care, perhaps by emergency room personnel.

The authors plan to follow study participants and assess outcomes at for 6-12 months. They also aim to include more patients to increase the study’s power.
 

Expanding the Technology

They are also interested to see whether the technology can determine which valve is affected; for example, whether the issue is aortic stenosis or mitral regurgitation.

A limitation of the study was its small sample size.

Commenting on the findings, Dan Roden, MD, professor of medicine, pharmacology, and biomedical informatics, senior vice president for personalized medicine at Vanderbilt University Medical Center, Nashville, Tennessee, and chair of the American Heart Association Council on Genomic and Precision Medicine, noted that it demonstrated the AI-based stethoscope “did extraordinarily well” in predicting VHD. 

“I see this as an emerging technology — using an AI-enabled stethoscope and perhaps combining it with other imaging modalities, like an AI-enabled echocardiogram built into your stethoscope,” said Dr. Roden.

“Use of these new tools to detect the presence of valvular disease, as well as the extent of valvular disease and the extent of other kinds of heart disease, will likely help to transform CVD care.” 

The study was funded by Eko Health Inc. Dr. Rancier and Dr. Roden have no relevant conflicts of interest.

VHD Common

Clinically significant VHD, indicating structural damage to heart valves, affects 1 in 10 adults older than 65 years. Patients may be asymptomatic or present to their PCP with an unspecific symptom like fatigue or malaise.

If VHD is undiagnosed and left untreated, patients could develop more severe symptoms, even be at risk for death, and their quality of life is significantly affected, said Dr. Rancier.

Cardiac auscultation, the current point-of-care clinical standard, has relatively low sensitivity for detecting VHD, leaving most patients undiagnosed.

The deep learning–based AI tool uses sound data to detect cardiac murmurs associated with clinically significant VHD. The device used in the study (Eko; Eko Health) is approved by the US Food and Drug Administration and is on the market.

The tool identifies background sounds that might affect the evaluation. “If there’s any noise or breath sounds, it tells me this is not a good heart sound, and asks me to record again,” said Dr. Rancier.

A doctor using the AI-assisted stethoscope carries out the auscultation exam with the sound data captured by a smartphone or tablet and sent to the AI server. “I get an answer in a second as to if there’s a murmur or not,” said Dr. Rancier.

Not only that, but the tool can determine if it’s a systolic or diastolic murmur, he added.
 

Real-World Population

The study enrolled a “real-world” population of 368 patients, median age 70 years, 61% female, 70% White, and 18% Hispanic without a prior VHD diagnosis or history of murmur, from three primary care clinics in Queens, New York, and Lawrence and Haverhill, Massachusetts. 

About 79% of the cohort had hypertension, 68% had dyslipidemia, and 38% had diabetes, “which aligns with the population in the US,” said Dr. Rancier.

Each study participant had a regular exam carried out by Dr. Rancier using a traditional stethoscope to detect murmurs and an exam by a technician with a digital stethoscope that collected phonocardiogram (PCG) data for analysis by AI.

In addition, each patient received an echocardiogram 1-2 weeks later to confirm whether clinically significant VHD was present. An expert panel of cardiologists also reviewed the patient’s PCG recordings to confirm the presence of audible murmurs.

Dr. Rancier and the expert panel were blinded to AI and echocardiogram results.

Researchers calculated performance metrics for both PCP auscultation and the AI in detecting audible VHD.

The study showed that AI improved sensitivity to detect audible VHD by over twofold compared with PCP auscultation (94.1% vs 41.2%), with limited impact on specificity (84.5% vs 95.5%).

Dr. Rancier stressed the importance of sensitivity because clinicians tend to under-detect murmurs. “You don’t want to miss those patients because the consequences of undiagnosed VHD are dire.”

The AI tool identified 22 patients with moderate or greater VHD who were previously undiagnosed, whereas PCPs identified eight previously undiagnosed patients with VHD.

Dr. Rancier sees this tool being used beyond primary care, perhaps by emergency room personnel.

The authors plan to follow study participants and assess outcomes at for 6-12 months. They also aim to include more patients to increase the study’s power.
 

Expanding the Technology

They are also interested to see whether the technology can determine which valve is affected; for example, whether the issue is aortic stenosis or mitral regurgitation.

A limitation of the study was its small sample size.

Commenting on the findings, Dan Roden, MD, professor of medicine, pharmacology, and biomedical informatics, senior vice president for personalized medicine at Vanderbilt University Medical Center, Nashville, Tennessee, and chair of the American Heart Association Council on Genomic and Precision Medicine, noted that it demonstrated the AI-based stethoscope “did extraordinarily well” in predicting VHD. 

“I see this as an emerging technology — using an AI-enabled stethoscope and perhaps combining it with other imaging modalities, like an AI-enabled echocardiogram built into your stethoscope,” said Dr. Roden.

“Use of these new tools to detect the presence of valvular disease, as well as the extent of valvular disease and the extent of other kinds of heart disease, will likely help to transform CVD care.” 

The study was funded by Eko Health Inc. Dr. Rancier and Dr. Roden have no relevant conflicts of interest.

Changes in tissue thickness in the back of the eye can correlate with worsening or improvement of renal problems and could help predict who will have worsening of kidney function, a new analysis report finds. 

The research, published in the journal Nature Communications, is the first to show an association between chronic kidney disease (CKD) and the thickness of the retinal and choroidal layers in the back of the eye as measured by optical coherence tomography (OCT), a noninvasive imaging technology commonly used to evaluate eye diseases such as age-related macular degeneration (AMD), diabetic eye disease, and retinal detachments.

“These are common scans that people get at the opticians and now in many hospitals,” said Neeraj Dhaun, MD, PhD, a professor of nephrology at the University of Edinburgh, Scotland. (Opticians in the United Kingdom are the equivalent of optometrists in North America.) 
 

CKD Severity Equals Thinner Retinas

“We scanned the back of eye of healthy people as well as patients with various types and degrees of kidney disease, and we found that two layers in the back of eye, the retina and the choroid, were thinner in patients with kidney disease compared to people who are healthy, and that the extent of this thinning predicts whether kidney function would decline going forward over a period of 2 or 3 years,” Dr. Dhaun, the corresponding author of the new paper, said.

The publication is a report of four different studies. The first study measured OCT metrics in 112 patients with CKD, 92 patients with a functional kidney transplant, and 86 control volunteers. The researchers found the retina was 5% thinner in patients with CKD than in healthy controls. They also found that patients with CKD had reduced macular volume: 8.44 ± .44 mm³ vs 8.73 ± .36 mm³ (P < .001). The choroid was also found to be thinner at each of three macular locations measured in patients with CKD vs control volunteers. At baseline, CKD and transplant patients had significantly lower estimated glomerular filtration rate (eGFR) at 55 ± 27 and 55 ± 24 mL/min/1.73 m² compared with control volunteers at 97 ± 14 mL/min/1.73 m².

The second study reported on OCT measurements and kidney histologic injury in 50 patients who had a kidney biopsy within 30 days of their OCT. It found that choroidal thinning at all three macular locations was independently associated with more extensive kidney scarring. 

The third study focused on 25 patients with kidney failure who had a kidney transplant. Their eGFR improved from 8 ± 3 to 58 ± 21 mL/min/1.73 m² in the first week after the transplant. The choroid in these patients thickened about 5% at 1 week and by about 10% at 1 month posttransplant. OCT of 22 kidney donors showed thickening of the choroid a week after nephrectomy before a tendency to thinning over the next year.

The fourth study found that for patients with stable CKD, every 1 mm3 decrease in macular volume correlated to an increased odds of a decline in eGFR by more than 10% at 1 year (2.48; 95% CI, 1.26-5.08; P = .01) and by more than 20% at 2 years (3.75; 95% CI, 1.26-5.08; P = .004).
 

Exploring the Kidney-Eye Connection 

The potential explanation for the correlation between retinal and choroidal thickness and kidney function is unclear, Dr. Dhaun said. 

“We don’t know the exact mechanisms, and these are difficult to define from studies in patients, which is why we are doing more work in animal models of kidney disease to see if we can establish the pathways that lead to the changes in the eye,” he said. 

“However,” Dr. Dhaun added, “what we do know is that kidney disease affects the whole body. For example, kidney disease can lead to high blood pressure and heart disease, as well as diseases in the brain, and it is these effects of kidney disease on the body as whole that we are probably picking up in the back of the eye.” 

OCT has the potential to make the monitoring of patients with CKD and kidney transplant more convenient than it is now, Dr. Dhaun said. “These scanners are available in the community, and what would be ideal at some point in the future is to be able to do a patient’s kidney health check in the community potentially incorporating OCT scanning alongside blood-pressure monitoring and other healthcare measures,” he said.

“The findings provide an exciting example of how noninvasive retinal imaging using OCT can provide quantitative biomarkers of systemic disease,” Amir Kashani, MD, PhD, the Boone Pickens Professor of Ophthalmology and Biomedical Engineering at the Wilmer Eye Institute of Johns Hopkins University in Baltimore, told this news organization. “It is striking that their findings demonstrate some potential of reversible changes in choroidal perfusion after kidney transplantation.”

The finding that choroidal thickness changes in CKD are at least partly reversible with kidney transplantation is a revelation, Dr. Kashani said, and may point to a greater role for ophthalmologists in managing systemic disease. 

“Ophthalmologists can and should use their unique experience and understanding of the eye to help monitor and manage systemic conditions in collaboration with our medicine colleagues,” he said. “There are many systemic diseases that can impact the eye and ophthalmologist are uniquely positioned to help interpret those findings.”

Dr. Kashani noted that a particular strength of the report was the comparison of choroidal measurements in patients who had kidney transplantation and those that had a nephrectomy. “The consistent direction of changes in these two groups suggests the study findings are real and meaningful,” he said.

The study was independently supported. Dr. Dhaun and co-authors report no relevant financial relationships. Dr. Kashani disclosed a financial relationship with Carl Zeiss Meditec.

TOPLINE:

Individuals with overweight or obesity and knee or hip osteoarthritis (OA) who used antiobesity medications and achieved slow-to-moderate weight loss had a lower risk for all-cause mortality than did those with weight gain or stable weight in a population-based cohort study emulating a randomized controlled trial. Patients who rapidly lost weight had mortality similar to those with weight gain or stable weight.

METHODOLOGY:

• The researchers used the IQVIA Medical Research Database to identify overweight or obese individuals with knee or hip OA; they conducted a hypothetical trial comparing the effects of slow-to-moderate weight loss (defined as 2%-10% of body weight) and rapid weight loss (defined as 5% or more of body weight) within 1 year of starting antiobesity medications.
• The final analysis included patients with a mean age of 60.9 years who met the criteria for treatment adherence to orlistat (n = 3028), sibutramine (n = 2919), or rimonabant (n = 797).
• The primary outcome was all-cause mortality over a 5-year follow-up period; secondary outcomes included hypertension, type 2 diabetes, and venous thromboembolism.

TAKEAWAY:

• All-cause mortality at 5 years was 5.3% with weight gain or stable weight, 4.0% with slow to moderate weight loss, and 5.4% with rapid weight loss.
• Hazard ratios for all-cause mortality were 0.72 (95% CI, 0.56-0.92) for slow to moderate weight loss and 0.99 (95% CI, 0.67-1.44) for the rapid weight loss group.
• Weight loss was associated with the secondary outcomes of reduced hypertension, type 2 diabetes, and venous thromboembolism in a dose-dependent manner.
• A slightly increased risk for cardiovascular disease occurred in the rapid weight loss group, compared with the weight gain or stable group, but this difference was not significant.

IN PRACTICE:

“Our finding that gradual weight loss by antiobesity medications lowers all-cause mortality, if confirmed by future studies, could guide policy-making and improve the well-being of patients with overweight or obesity and knee or hip OA,” the researchers wrote.

SOURCE:

The lead author on the study was Jie Wei, MD, of Central South University, Changsha, China. The study was published online in Arthritis & Rheumatology.

LIMITATIONS:

Study limitations included the inability to control for factors such as exercise, diet, and disease severity; the inability to assess the risk for cause-specific mortality; and the inability to account for the impact of pain reduction and improved function as a result of weight loss.

DISCLOSURES:

The study was supported by the National Key Research and Development Plan, the National Natural Science Foundation of China, the Project Program of National Clinical Research Center for Geriatric Disorders, the Natural Science Foundation of Hunan Province, the Central South University Innovation-Driven Research Programme, and the Science and Technology Innovation Program of Hunan Province. The researchers had no financial conflicts to disclose.
