Please note that this is a commentary, an opinion piece: my opinion. The statements here do not necessarily represent those of this news organization or any of the myriad people or institutions that comprise this corner of the human universe.

Some days, speaking as a long-time physician and editor, I wish that there were no such things as race or ethnicity or even geographic origin for that matter. We can’t get away from sex, gender, disability, age, or culture. I’m not sure about religion. I wish people were just people.

But race is deeply embedded in the American experience — an almost invisible but inevitable presence in all of our thoughts and expressions about human activities.

In medical education (for eons it seems) the student has been taught to mention race in the first sentence of a given patient presentation, along with age and sex. In human epidemiologic research, race is almost always a studied variable. In clinical and basic medical research, looking at the impact of race on this, that, or the other is commonplace. “Mixed race not otherwise specified” is ubiquitous in the United States yet blithely ignored by most who tally these statistics. Race is rarely gene-specific. It is more of a social and cultural construct but with plainly visible overt phenotypic markers — an almost infinite mix of daily reality.

Our country, and much of Western civilization in 2024, is based on the principle that all men are created equal, although the originators of that notion were unaware of their own “equity-challenged” situation.

Many organizations, in and out of government, are now understanding, developing, and implementing programs (and thought/language patterns) to socialize diversity, equity, and inclusion (known as DEI) into their culture. It should not be surprising that many who prefer the status quo are not happy with the pressure from this movement and are using whatever methods are available to them to prevent full DEI. Such it always is.

The trusty Copilot from Bing provides these definitions:

• Diversity refers to the presence of variety within the organizational workforce. This includes aspects such as gender, culture, ethnicity, religion, disability, age, and opinion.
• Equity encompasses concepts of fairness and justice. It involves fair compensation, substantive equality, and addressing societal disparities. Equity also considers unique circumstances and adjusts treatment to achieve equal outcomes.
• Inclusion focuses on creating an organizational culture where all employees feel heard, fostering a sense of belonging and integration.

I am more than proud that my old domain of peer-reviewed, primary source, medical (and science) journals is taking a leading role in this noble, necessary, and long overdue movement for medicine.

As the central repository and transmitter of new medical information, including scientific studies, clinical medicine reports, ethics measures, and education, medical journals (including those deemed prestigious) have historically been among the worst offenders in perpetuating non-DEI objectives in their leadership, staffing, focus, instructions for authors, style manuals, and published materials.

This issue came to a head in March 2021 when a JAMA podcast about racism in American medicine was followed by this promotional tweet: “No physician is racist, so how can there be structural racism in health care?”

Reactions and actions were rapid, strong, and decisive. After an interregnum at JAMA, a new editor in chief, Kirsten Bibbins-Domingo, PhD, MD, MAS, was named. She and her large staff of editors and editorial board members from the multijournal JAMA Network joined a worldwide movement of (currently) 56 publishing organizations representing 15,000 journals called the Joint Commitment for Action on Inclusion and Diversity in Publishing.

A recent JAMA editorial with 29 authors describes the entire commitment initiative of publishers-editors. It reports JAMA Network data from 2023 and 2024 from surveys of 455 editors (a 91% response rate) about their own gender (five choices), ethnic origins or geographic ancestry (13 choices), and race (eight choices), demonstrating considerable progress toward DEI goals. The survey’s complex multinational classifications may not jibe with the categorizations used in some countries (too bad that “mixed” is not “mixed in” — a missed opportunity).

This encouraging movement will not fix it all. But when people of certain groups are represented at the table, that point of view is far more likely to make it into the lexicon, language, and omnipresent work products, potentially changing cultural norms. Even the measurement of movement related to disparity in healthcare is marred by frequent variations of data accuracy. More consistency in what to measure can help a lot, and the medical literature can be very influential.

A personal anecdote: When I was a professor at UC Davis in 1978, Allan Bakke, MD, was my student. Some of you will remember the saga of affirmative action on admissions, which was just revisited in the light of a recent decision by the US Supreme Court.

Back in 1978, the dean at UC Davis told me that he kept two file folders on the admission processes in different desk drawers. One categorized all applicants and enrollees by race, and the other did not. Depending on who came to visit and ask questions, he would choose one or the other file to share once he figured out what they were looking for (this is not a joke).

The strength of the current active political pushback against the entire DEI movement has deep roots and should not be underestimated. There will be a lot of to-ing and fro-ing.

French writer Victor Hugo is credited with stating, “There is nothing as powerful as an idea whose time has come.” A majority of Americans, physicians, and other healthcare professionals believe in basic fairness. The time for DEI in all aspects of medicine is now.

Dr. Lundberg, editor in chief of Cancer Commons, disclosed having no relevant financial relationships.

In most Western countries, professional standards dictate that physicians should practice medicine with compassion. Patients also expect compassionate care from physicians because it represents a model capable of providing greater patient satisfaction, fostering better doctor-patient relationships, and enabling better psychological states among patients.

The etymology of the term “compassion” derives from the Latin roots “com,” meaning “together with,” and “pati,” meaning “to endure or suffer.” When discussing compassion, it is necessary to distinguish it from empathy, a term generally used to refer to cognitive or emotional processes in which the perspective of the other (in this case, the patient) is taken. Compassion implies or requires empathy and includes the desire to help or alleviate the suffering of others. Compassion in the medical context is likely a specific instance of a more complex adaptive system that has evolved, not only among humans, to motivate recognition and assistance when others suffer.
 

Compassion Fatigue

Physicians’ compassion is expected by patients and the profession. It is fundamental for effective clinical practice. Although compassion is central to medical practice, most research related to the topic has focused on “compassion fatigue,” which is understood as a specific type of professional burnout, as if physicians had a limited reserve of compassion that dwindles or becomes exhausted with use or overuse. This is one aspect of a much more complex problem, in which compassion represents the endpoint of a dynamic process that encompasses the influences of the physician, the patient, the clinic, and the institution.

Compassion Capacity: Conditioning Factors

Chronic exposure of physicians to conflicting work demands may be associated with the depletion of their psychological resources and, consequently, emotional and cognitive fatigue that can contribute to poorer work outcomes, including the ability to express compassion.

Rates of professional burnout in medicine are increasing. The driving factors of this phenomenon are largely rooted in organizations and healthcare systems and include excessive workloads, inefficient work processes, administrative burdens, and lack of input or control by physicians regarding issues concerning their work life. The outcome often is early retirement of physicians, a current, increasingly widespread phenomenon and a critical issue not only for the Italian National Health Service but also for other healthcare systems worldwide.
 

Organizational and Personal Values

There is no clear empirical evidence supporting the hypothesis that working in healthcare environments experienced as discrepant with one’s own values has negative effects on key professional outcomes. However, a study published in the Journal of Internal Medicine highlighted the overall negative effect of misalignment between system values and physicians’ personal values, including impaired ability to provide compassionate care, as well as reduced job satisfaction, burnout, absenteeism, and considering the possibility of early retirement. Results from 1000 surveyed professionals indicate that physicians’ subjective competence in providing compassionate care may remain high, but their ability to express it is compromised. From data analysis, the authors hypothesize that when working in environments with discrepant values, occupational contingencies may repeatedly require physicians to set aside their personal values, which can lead them to refrain from using available skills to keep their performance in line with organizational requirements.

These results and hypotheses are not consistent with the notion of compassion fatigue as a reflection of the cost of care resulting from exposure to repeated suffering. Previous evidence shows that expressing compassion in healthcare facilitates greater understanding, suggesting that providing compassion does not impoverish physicians but rather supports them in the effectiveness of interventions and in their satisfaction.

In summary, this study suggests that what prevents compassion is the inability to provide it when hindered by factors related to the situation in which the physician operates. Improving compassion does not simply depend on motivating individual professionals to be more compassionate or on promoting fundamental skills, but probably on the creation of organizational and clinical conditions in which physician compassion can thrive.

Whether you have totally bought into the “obesity is a disease” paradigm or are still in denial, you must admit that the development of a suite of effective weight loss medications has created a tsunami of interest and economic activity in this country on a scale not seen since the Beanie Baby craze of the mid-1990s. But, obesity management is serious business. While most of those soft cuddly toys are gathering dust in shoeboxes across this country, weight loss medications are likely to be the vanguard of rapidly evolving revolution in healthcare management that will be with us for the foreseeable future.

Most thoughtful folks who purchased Beanie Babies in 1994 had no illusions and knew that in a few short years this bubble of soft cuddly toys was going to burst. However, do those of us on the front line of medical care know what the future holds for the patients who are being prescribed or are scavenging those too-good-to-be-true medications?

My guess is that in the long run we will need a combination of some serious tinkering by the pharmaceutical industry and a trek up some steep learning curves before we eventually arrive at a safe and effective chemical management for obese patients. I recently read an article by an obesity management specialist at Harvard Medical School who voiced her concerns that we are missing an opportunity to make this explosion of popularity in GLP-1 drugs into an important learning experience.

In an opinion piece in JAMA Internal Medicine, Dr. Fatima Cody Stanford and her coauthors argue that we, actually the US Food and Drug Administration (FDA), is over-focused on weight loss in determining the efficacy of anti-obesity medications. Dr. Stanford and colleagues point out that when a patient loses weight it isn’t just fat — it is complex process that may include muscle and bone mineralization as well. She has consulted for at least one obesity-drug manufacturer and says that these companies have the resources to produce data on body composition that could help clinicians create management plans that would address the patients’ overall health. However, the FDA has not demanded this broader and deeper assessment of general health when reviewing the drug trials.

I don’t think we can blame the patients for not asking whether they will healthier while taking these medications. They have already spent a lifetime, even if it is just a decade, of suffering as the “fat one.” A new outfit and a look in the mirror can’t help but make them feel better ... in the short term anyway. We as physicians must shoulder some of the blame for focusing on weight. Our spoken or unspoken message has been “Lose weight and you will be healthier.” We may make our message sound more professional by tossing around terms like “BMI,” but as Dr. Stanford points out, “we have known BMI is a flawed metric for a long time.”

There is the notion that obese people have had to build more muscle to help them carry around the extra weight, so that we should expect them to lose that extra muscle along with the fat. However, in older adults there is an entity called sarcopenic obesity, in which the patient doesn’t have that extra muscle to lose.

In a brief Internet research venture, I could find little on the subject of muscle loss and GLP-1s, other than “it can happen.” And, nothing on the effect in adolescents. And that is one of Dr. Stanford’s points. We just don’t know. She said that looking at body composition can be costly and not something that the clinician can do. However, as far as muscle mass is concerned, we need to be alert to the potential for loss. Simple assessments of strength can help us tailor our management to the specific patient’s need.

The bottom line is this ... now that we have effective medications for “weight loss,” we need to redefine the relationship between weight and health. “We” means us as clinicians. It means the folks at FDA. And, if we can improve our messaging, it will osmose to the rest of the population. Just because you’ve dropped two dress sizes doesn’t mean you’re healthy.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

However, as far as muscle mass is concerned, we need to be alert to the potential for loss. Simple assessments of strength can help us tailor our management to the specific patient’s need.

The bottom line is this ... now that we have effective medications for “weight loss,” we need to redefine the relationship between weight and health. “We” means us as clinicians. It means the folks at FDA. And, if we can improve our messaging, it will osmose to the rest of the population. Just because you’ve dropped two dress sizes doesn’t mean you’re healthy.

Whether you have totally bought into the “obesity is a disease” paradigm or are still in denial, you must admit that the development of a suite of effective weight loss medications has created a tsunami of interest and economic activity in this country on a scale not seen since the Beanie Baby craze of the mid-1990s. But, obesity management is serious business. While most of those soft cuddly toys are gathering dust in shoeboxes across this country, weight loss medications are likely to be the vanguard of rapidly evolving revolution in healthcare management that will be with us for the foreseeable future.

Most thoughtful folks who purchased Beanie Babies in 1994 had no illusions and knew that in a few short years this bubble of soft cuddly toys was going to burst. However, do those of us on the front line of medical care know what the future holds for the patients who are being prescribed or are scavenging those too-good-to-be-true medications?

My guess is that in the long run we will need a combination of some serious tinkering by the pharmaceutical industry and a trek up some steep learning curves before we eventually arrive at a safe and effective chemical management for obese patients. I recently read an article by an obesity management specialist at Harvard Medical School who voiced her concerns that we are missing an opportunity to make this explosion of popularity in GLP-1 drugs into an important learning experience.

In an opinion piece in JAMA Internal Medicine, Dr. Fatima Cody Stanford and her coauthors argue that we, actually the US Food and Drug Administration (FDA), is over-focused on weight loss in determining the efficacy of anti-obesity medications. Dr. Stanford and colleagues point out that when a patient loses weight it isn’t just fat — it is complex process that may include muscle and bone mineralization as well. She has consulted for at least one obesity-drug manufacturer and says that these companies have the resources to produce data on body composition that could help clinicians create management plans that would address the patients’ overall health. However, the FDA has not demanded this broader and deeper assessment of general health when reviewing the drug trials.

I don’t think we can blame the patients for not asking whether they will healthier while taking these medications. They have already spent a lifetime, even if it is just a decade, of suffering as the “fat one.” A new outfit and a look in the mirror can’t help but make them feel better ... in the short term anyway. We as physicians must shoulder some of the blame for focusing on weight. Our spoken or unspoken message has been “Lose weight and you will be healthier.” We may make our message sound more professional by tossing around terms like “BMI,” but as Dr. Stanford points out, “we have known BMI is a flawed metric for a long time.”

There is the notion that obese people have had to build more muscle to help them carry around the extra weight, so that we should expect them to lose that extra muscle along with the fat. However, in older adults there is an entity called sarcopenic obesity, in which the patient doesn’t have that extra muscle to lose.

In a brief Internet research venture, I could find little on the subject of muscle loss and GLP-1s, other than “it can happen.” And, nothing on the effect in adolescents. And that is one of Dr. Stanford’s points. We just don’t know. She said that looking at body composition can be costly and not something that the clinician can do.

Breastfeeding by women with multiple sclerosis (MS) or neuromyelitis optica spectrum disorder (NMOSD) who are taking monoclonal antibodies (mAbs) appears to be safe for infants, new research confirmed.

Registry data showed no differences in health or development in the first 3 years of life among infants exposed to natalizumab, ocrelizumab, rituximab, or ofatumumab, compared with unexposed infants.

“Most monoclonal antibody medications for multiple sclerosis are not currently approved for use while a mother is breastfeeding,” even though the disease can develop during a person’s reproductive years, study investigator Kerstin Hellwig, MD, with Ruhr University in Bochum, Germany, said in a news release.

“Our data show infants exposed to these medications through breastfeeding experienced no negative effects on health or development within the first 3 years of life,” Dr. Hellwig said.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.
 

Registry Data and Analysis

Using the German MS and Pregnancy Registry, researchers identified 183 infants born to mothers taking mAbs while breastfeeding — 180 with a diagnosis of MS and three with a diagnosis of NMOSD. The infants were matched to 183 unexposed infants (control group).

Exposure to mAbs during lactation started a median of 19 days postpartum and lasted for a median of 172 days. The most commonly used mAb during lactation was natalizumab (125 women), followed by ocrelizumab (34 women), rituximab (11 women), and ofatumumab (10 women).

Among the entire infant cohort, two were first exposed to natalizumab and then ocrelizumab; one was exposed to rituximab and then ocrelizumab; three had been previously breastfed on glatiramer acetate and two on interferons.

The primary outcomes were hospitalizations, antibiotic use, developmental delay, and weight during the first 3 years of life in mAb-exposed versus unexposed infants.

In adjusted regression analyses, mAb exposure during breastfeeding was not significantly associated with annual hospitalization (rate ratio [RR], 1.23; P = .473), annual systemic antibiotic use (RR, 1.55; P = .093), developmental delay (odds ratio, 1.16; P = .716), or weight.

A limitation of the study was that only about a third of the infants were followed for the full 3 years. Therefore, Dr. Hellwig said, the results for the third year of life are less meaningful than for years 1 and 2.
 

‘Reassuring’ Data

Reached for comment, Edith L. Graham, MD, Department of Neurology, Multiple Sclerosis and Neuroimmunology, Northwestern University, Chicago, Illinois, noted that this is the largest group of breastfed infants exposed to mAbs used to treat MS and said the data provide “reassuring infant outcomes with no increase in hospitalization, antibiotic use, or developmental delay.”

Dr. Graham noted that recent publications have reported more on the use of anti-CD20 mAbs (ocrelizumab/rituximab/ofatumumab) while breastfeeding, “and this study adds data for patients on natalizumab.”

“It will be important to know how infusion timing after birth impacts transfer of monoclonal antibodies depending on the milk stage as it transitions from colostrum to mature milk in the first month postpartum,” Dr. Graham said.

“While infection rates of infants are reassuring, data on allergies in the exposed infants would be interesting to look at as well,” she added. “While these infusions are not orally bioavailable, we do not know the full extent of impact on the neonatal gut microbiome.”

In addition, Dr. Graham said it would be important to know whether drugs administered monthly, such as natalizumab and ofatumumab, accumulate in the breast milk at higher levels than medications such as ocrelizumab and rituximab, which are administered twice a year.

The German MS and pregnancy registry was partly supported by the Innovation Fund of the Federal Joint Committee, Almirall Hermal GmbH, Biogen GmbH Germany, Hexal AG, Merck Serono GmbH, Novartis Pharma GmbH, Roche Deutschland GmbH, Sanofi Genzyme, and Teva GmbH. Dr. Hellwig and Dr. Graham had no relevant disclosures.

TOPLINE:

A clinical trial of preterm infants with inguinal hernia found that performing repair after discharge from the neonatal intensive care unit (NICU) resulted in fewer adverse events than procedures prior to discharge.

METHODOLOGY:

• The study compared the safety of repair before discharge from the NICU with repair after discharge and post-55 weeks gestational plus chronological age (postmenstrual age).
• The study randomized 338 infants from 39 US hospitals to early or late repair; of the 320 infants who had the surgery, 86% were male, 30% were Black, and 59% were White.
• The primary outcome was the occurrence of at least one serious adverse event over the 10-month observation period, including apnea requiring respiratory intervention, intubation for more than 2 days, bradycardia requiring pharmacological intervention, or death.
• Secondary outcomes included a total number of days in the hospital, including the initial NICU stay after randomization, postoperative hospitalization, and any inpatient days due to hospital readmission over the course of the following 10-month period.

TAKEAWAY:

• Infants who underwent late repair had a lower probability of having at least one serious adverse event: 28% had at least one adverse event in the early group vs 18% in the late group.
• Infants in the late repair group had shorter stays in the NICU after randomization, as well as fewer hospital days following surgery.
• Late repair provided the greatest benefit to infants with a gestational age younger than 28 weeks and those who had bronchopulmonary dysplasia.
• Hernias resolved spontaneously in 4% of infants in the early repair group and 11% in the late group, which the authors said supports delaying hernia repair.

IN PRACTICE:

“The decision to treat the inguinal hernia with an early or late repair strategy likely does not influence the overall duration of the neonatal intensive care unit stay but may hasten the discharge by several days if later repair is chosen, which is likely important to parents and neonatologists.”

SOURCE:

The study was published online in JAMA. It was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Martin L. Blakely, MD, MS, from the Department of Surgery at the University of Texas Health Science Center, Houston, Texas, is the corresponding author.

LIMITATIONS:

This study had a modest sample size, an issue compounded by some subjects withdrawing from the trial. The randomization rate was lower than expected. The trial was also discontinued early due to meeting a prespecified stopping rule for effectiveness.

DISCLOSURES:

Study authors report grant support from the US Department of Defense, personal fees, author royalties, and institutional contracts with various companies including Medicem, Fresenius Kabi, Baxter, and Mead Johnson.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are often not prescribed or accessible to people who could benefit from them, a trio of new studies suggested.

First approved for the treatment of type 2 diabetes, the indications for SGLT2 inhibitors and GLP-1 RA medications have now been extended to people with obesity, heart failure, and chronic kidney disease.

The papers were presented at the American Heart Association (AHA) Epidemiology and Prevention | Lifestyle and Cardiometabolic Scientific Sessions 2024.

The new data show there is “work to be done in terms of access and equity to these treatments,” Robert H. Eckel, MD, who was not involved in the research, said in a conference statement.

“There is no question that the cost of these medications is high, yet when issues go beyond coverage and include sociodemographic and racial differences that influence treatment, these major issues need to be evaluated and addressed,” said Dr. Eckel, professor emeritus of medicine, Division of Endocrinology, Metabolism, and Diabetes, University of Colorado Anschutz Medical Campus, Denver, and a past president of the AHA.
 

Low Prescription Rates

In one study, researchers analyzed health records for 18,164 adults with obesity (mean age, 51 years; 64% women; mean body mass index [BMI], 36 kg/m2) who had health insurance covering semaglutide and liraglutide (GLP-1 RAs) and tirzepatide (GLP-1/glucose-dependent insulinotropic polypeptide RA). The cohort was 54% White, 35% Black, and 5% Asian.

Only about 3% of eligible adults were prescribed one of these medications, reported Meron Haile, BS, a second-year medical student at Johns Hopkins University School of Medicine in Baltimore, and colleagues.

The likelihood of prescription was lower among Black patients (odds ratio [OR], 0.76) and men (OR, 0.54) and higher in people with higher BMI (OR, 1.06 per 1-unit higher BMI).

Living in a neighborhood with a higher area deprivation index or lower income was not independently associated with the likelihood of prescription.

Individuals with diabetes or hypertension were more likely to be prescribed one of these medications (OR, 3.52 and 1.36, respectively).

“While prescription rates for new obesity therapies are low among the overall population, we saw pronounced lower accessibility among Black adults, who exhibit a higher burden of severe obesity, hypertension, and type 2 diabetes,” Haile said in a conference statement.

“There is a crucial need for understanding prescription practices for obesity medications and to facilitate similar access among people in all races and ethnic groups,” Haile added.

Similar findings emerged in a separate study, in which researchers analyzed the health records of 687,165 adults with type 2 diabetes treated at six large health systems from 2014 to 2022.

The rate of annual pharmacy dispensing of SGLT2 inhibitors and GLP-1 RA medications rose during the study period, but there were clear racial and ethnic differences in prescribing.

In fully adjusted models, SGLT2 inhibitors dispensing was lower for American Indian/Alaska Native (AI/AN; OR, 0.80), Black (OR, 0.89), and Hispanic (OR, 0.87) individuals than for White patients.

Likewise, GLP-1 RA dispensing was also lower for AI/AN (OR, 0.78), Asian (OR, 0.50), Black (OR, 0.86), Hawaiian/Pacific Islander (OR, 0.52), and Hispanic (OR, 0.69) patients than for White patients.

“It’s possible that not all patients have equal access to information about these medications or that not all patients are equally comfortable asking their doctors about them,” lead author Luis A. Rodriguez, PhD, research scientist at Kaiser Permanente’s Northern California Division of Research, Oakland, told this news organization.

“We also don’t know if the cost of the new medications contributed to what we found or if some patients prefer to keep taking a pill rather than switch to some of the GLP-1 receptor agonists that are self-injectable medications. We need to learn more about why this is happening,” Dr. Rodriguez said.
 

‘Concerning’ Data Raise Key Questions

The third study explored how often prescribing recommendations for SGLT2 inhibitors are followed.

“Our study revealed a significant gap between the recommendations for prescribing SGLT2 inhibitors and the actual prescription rates among patients who could benefit from them,” Jung-Im Shin, MD, PhD, with the Welch Center for Prevention, Epidemiology, and Clinical Research, Johns Hopkins University, Baltimore, told this news organization.

“This could have important implications for patient care and outcomes, as SGLT2 inhibitors have been shown to be effective for heart and kidney protection in people with high-risk type 2 diabetes, chronic kidney disease, or heart failure,” Dr. Shin said.

Dr. Shin and colleagues analyzed the health records for more than 700,000 adults with type 2 diabetes and 2.5 million people without type 2 diabetes, who received care in 28 US health systems from 2022 to 2023.

Among people with type 2 diabetes recommended for first-line SGLT2 inhibitors treatment, only 12% received a prescription for a SGLT2 inhibitor, and there was no significant difference in prescription between people who met the criteria for first-line SGLT2 inhibitors treatment vs people who did not meet the criteria.

Among people without type 2 diabetes, SGLT2 inhibitor prescription was substantially lower, with only about 3% of people with conditions that are guideline-recommended for SGLT2 inhibitors receiving a prescription.

SGLT2 inhibitor prescription rates varied across health systems; however, less than 30% of people who met guideline criteria received a SGLT2 inhibitors prescription across all health systems in the study.

“Barriers to SGLT2 inhibitor prescription include limited insurance coverage, prohibitive out-of-pocket costs, formulary restrictions, and lack of physicians’ awareness or familiarity regarding benefits and appropriate indications for SGLT2 inhibitors,” Dr. Shin said.

“Efforts to improve access and affordability of SGLT2 inhibitors along with strategies to educate both patients and providers on the updated guidelines for SGLT2 inhibitors use may increase adoption,” Dr. Shin added.

In a conference recording, Dr. Eckel said he found it “particularly concerning” that among patients with insurance to help pay for these medications, “there were still discrepancies” between prescriptions to Asian and Black vs White patients, “who are being prescribed these important medications.”

“Why these medications are not being offered more regularly by healthcare providers” needs to be addressed, Dr. Eckel said. “I think part of it is ignorance and inadequate education as to their new indications for treatment of diseases that go beyond type 2 diabetes,” he noted.

None of the studies had commercial funding. The authors had no relevant disclosures.

“While prescription rates for new obesity therapies are low among the overall population, we saw pronounced lower accessibility among Black adults, who exhibit a higher burden of severe obesity, hypertension, and type 2 diabetes,” Haile said in a conference statement.

“There is a crucial need for understanding prescription practices for obesity medications and to facilitate similar access among people in all races and ethnic groups,” Haile added.

Similar findings emerged in a separate study, in which researchers analyzed the health records of 687,165 adults with type 2 diabetes treated at six large health systems from 2014 to 2022.

The rate of annual pharmacy dispensing of SGLT2 inhibitors and GLP-1 RA medications rose during the study period, but there were clear racial and ethnic differences in prescribing.

In fully adjusted models, SGLT2 inhibitors dispensing was lower for American Indian/Alaska Native (AI/AN; OR, 0.80), Black (OR, 0.89), and Hispanic (OR, 0.87) individuals than for White patients.

Likewise, GLP-1 RA dispensing was also lower for AI/AN (OR, 0.78), Asian (OR, 0.50), Black (OR, 0.86), Hawaiian/Pacific Islander (OR, 0.52), and Hispanic (OR, 0.69) patients than for White patients.

“It’s possible that not all patients have equal access to information about these medications or that not all patients are equally comfortable asking their doctors about them,” lead author Luis A. Rodriguez, PhD, research scientist at Kaiser Permanente’s Northern California Division of Research, Oakland, told this news organization.

“We also don’t know if the cost of the new medications contributed to what we found or if some patients prefer to keep taking a pill rather than switch to some of the GLP-1 receptor agonists that are self-injectable medications. We need to learn more about why this is happening,” Dr. Rodriguez said.
 

‘Concerning’ Data Raise Key Questions

The third study explored how often prescribing recommendations for SGLT2 inhibitors are followed.

“Our study revealed a significant gap between the recommendations for prescribing SGLT2 inhibitors and the actual prescription rates among patients who could benefit from them,” Jung-Im Shin, MD, PhD, with the Welch Center for Prevention, Epidemiology, and Clinical Research, Johns Hopkins University, Baltimore, told this news organization.

“This could have important implications for patient care and outcomes, as SGLT2 inhibitors have been shown to be effective for heart and kidney protection in people with high-risk type 2 diabetes, chronic kidney disease, or heart failure,” Dr. Shin said.

Dr. Shin and colleagues analyzed the health records for more than 700,000 adults with type 2 diabetes and 2.5 million people without type 2 diabetes, who received care in 28 US health systems from 2022 to 2023.

Among people with type 2 diabetes recommended for first-line SGLT2 inhibitors treatment, only 12% received a prescription for a SGLT2 inhibitor, and there was no significant difference in prescription between people who met the criteria for first-line SGLT2 inhibitors treatment vs people who did not meet the criteria.

Among people without type 2 diabetes, SGLT2 inhibitor prescription was substantially lower, with only about 3% of people with conditions that are guideline-recommended for SGLT2 inhibitors receiving a prescription.

SGLT2 inhibitor prescription rates varied across health systems; however, less than 30% of people who met guideline criteria received a SGLT2 inhibitors prescription across all health systems in the study.

“Barriers to SGLT2 inhibitor prescription include limited insurance coverage, prohibitive out-of-pocket costs, formulary restrictions, and lack of physicians’ awareness or familiarity regarding benefits and appropriate indications for SGLT2 inhibitors,” Dr. Shin said.

“Efforts to improve access and affordability of SGLT2 inhibitors along with strategies to educate both patients and providers on the updated guidelines for SGLT2 inhibitors use may increase adoption,” Dr. Shin added.

In a conference recording, Dr. Eckel said he found it “particularly concerning” that among patients with insurance to help pay for these medications, “there were still discrepancies” between prescriptions to Asian and Black vs White patients, “who are being prescribed these important medications.”

“Why these medications are not being offered more regularly by healthcare providers” needs to be addressed, Dr. Eckel said. “I think part of it is ignorance and inadequate education as to their new indications for treatment of diseases that go beyond type 2 diabetes,” he noted.

None of the studies had commercial funding. The authors had no relevant disclosures.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors and glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are often not prescribed or accessible to people who could benefit from them, a trio of new studies suggested.

First approved for the treatment of type 2 diabetes, the indications for SGLT2 inhibitors and GLP-1 RA medications have now been extended to people with obesity, heart failure, and chronic kidney disease.

The papers were presented at the American Heart Association (AHA) Epidemiology and Prevention | Lifestyle and Cardiometabolic Scientific Sessions 2024.

The new data show there is “work to be done in terms of access and equity to these treatments,” Robert H. Eckel, MD, who was not involved in the research, said in a conference statement.

“There is no question that the cost of these medications is high, yet when issues go beyond coverage and include sociodemographic and racial differences that influence treatment, these major issues need to be evaluated and addressed,” said Dr. Eckel, professor emeritus of medicine, Division of Endocrinology, Metabolism, and Diabetes, University of Colorado Anschutz Medical Campus, Denver, and a past president of the AHA.
 

Low Prescription Rates

In one study, researchers analyzed health records for 18,164 adults with obesity (mean age, 51 years; 64% women; mean body mass index [BMI], 36 kg/m2) who had health insurance covering semaglutide and liraglutide (GLP-1 RAs) and tirzepatide (GLP-1/glucose-dependent insulinotropic polypeptide RA). The cohort was 54% White, 35% Black, and 5% Asian.

Only about 3% of eligible adults were prescribed one of these medications, reported Meron Haile, BS, a second-year medical student at Johns Hopkins University School of Medicine in Baltimore, and colleagues.

The likelihood of prescription was lower among Black patients (odds ratio [OR], 0.76) and men (OR, 0.54) and higher in people with higher BMI (OR, 1.06 per 1-unit higher BMI).

Living in a neighborhood with a higher area deprivation index or lower income was not independently associated with the likelihood of prescription.

Individuals with diabetes or hypertension were more likely to be prescribed one of these medications (OR, 3.52 and 1.36, respectively).

“While prescription rates for new obesity therapies are low among the overall population, we saw pronounced lower accessibility among Black adults, who exhibit a higher burden of severe obesity, hypertension, and type 2 diabetes,” Haile said in a conference statement.

Most survivors of childhood cancer don’t meet surveillance guidelines that recommend screening for adult cancers or other long-term adverse effects of treatment, according to a new study.

Among childhood cancer survivors in Ontario, Canada, who faced an elevated risk due to chemotherapy or radiation treatments, 53% followed screening recommendations for cardiomyopathy, 13% met colorectal cancer screening guidelines, and 6% adhered to breast cancer screening guidelines.

“Although over 80% of children newly diagnosed with cancer will become long-term survivors, as many as four out of five of these survivors will develop a serious or life-threatening late effect of their cancer therapy by age 45,” lead author Jennifer Shuldiner, PhD, MPH, a scientist at Women’s College Hospital Institute for Health Systems Solutions and Virtual Care in Toronto, told this news organization.

For instance, the risk for colorectal cancer in childhood cancer survivors is two to three times higher than it is among the general population, and the risk for breast cancer is similar between those who underwent chest radiation and those with a BRCA mutation. As many as 50% of those who received anthracycline chemotherapy or radiation involving the heart later develop cardiotoxicity.

The North American Children’s Oncology Group has published long-term follow-up guidelines for survivors of childhood cancer, yet many survivors don’t follow them because of lack of awareness or other barriers, said Dr. Shuldiner.

“Prior research has shown that many survivors do not complete these recommended tests,” she said. “With better knowledge of this at-risk population, we can design, test, and implement appropriate interventions and supports to tackle the issues.”

The study was published online on March 11 in CMAJ. 
 

Changes in Adherence 

The researchers conducted a retrospective population-based cohort study analyzing Ontario healthcare administrative data for adult survivors of childhood cancer diagnosed between 1986 and 2014 who faced an elevated risk for therapy-related colorectal cancer, breast cancer, or cardiomyopathy. The research team then assessed long-term adherence to the North American Children’s Oncology Group guidelines and predictors of adherence.

Among 3241 survivors, 3205 (99%) were at elevated risk for cardiomyopathy, 327 (10%) were at elevated risk for colorectal cancer, and 234 (7%) were at elevated risk for breast cancer. In addition, 2806 (87%) were at risk for one late effect, 345 (11%) were at risk for two late effects, and 90 (3%) were at risk for three late effects.

Overall, 53%, 13%, and 6% were adherent to their recommended surveillance for cardiomyopathy, colorectal cancer, and breast cancer, respectively. Over time, adherence increased for colorectal cancer and cardiomyopathy but decreased for breast cancer.

In addition, patients who were older at diagnosis were more likely to follow screening guidelines for colorectal and breast cancers, whereas those who were younger at diagnosis were more likely to follow screening guidelines for cardiomyopathy.

During a median follow-up of 7.8 years, the proportion of time spent adherent was 43% for cardiomyopathy, 14% for colorectal cancer, and 10% for breast cancer.

Survivors who attended a long-term follow-up clinic in the previous year had low adherence rates as well, though they were higher than in the rest of the cohort. In this group, the proportion of time that was spent adherent was 71% for cardiomyopathy, 27% for colorectal cancer, and 15% for breast cancer.

Shuldiner and colleagues are launching a research trial to determine whether a provincial support system can help childhood cancer survivors receive the recommended surveillance. The support system provides information about screening recommendations to survivors as well as reminders and sends key information to their family doctors.

“We now understand that childhood cancer survivors need help to complete the recommended tests,” said Dr. Shuldiner. “If the trial is successful, we hope it will be implemented in Ontario.” 
 

Survivorship Care Plans 

Low screening rates may result from a lack of awareness about screening recommendations and the negative long-term effects of cancer treatments, the study authors wrote. Cancer survivors, caregivers, family physicians, specialists, and survivor support groups can share the responsibility of spreading awareness and adhering to guidelines, they noted. In some cases, a survivorship care plan (SCP) may help.

“SCPs are intended to improve adherence by providing follow-up information and facilitating the transition from cancer treatment to survivorship and from pediatric to adult care,” Adam Yan, MD, a staff oncologist and oncology informatics lead at the Hospital for Sick Children in Toronto, told this news organization.

Dr. Yan, who wasn’t involved with this study, has researched surveillance adherence for secondary cancers and cardiac dysfunction among childhood cancer survivors. He and his colleagues found that screening rates were typically low among survivors who faced high risks for cardiac dysfunction and breast, colorectal, or skin cancers.

However, having a survivorship care plan seemed to help, and survivors treated after 1990 were more likely to have an SCP.

“SCP possession by high-risk survivors was associated with increased breast, skin, and cardiac surveillance,” he said. “It is uncertain whether SCP possession leads to adherence or whether SCP possession is a marker of survivors who are focused on their health and thus likely to adhere to preventive health practices, including surveillance.”

The study was funded by the Canadian Institutes of Health Research and ICES, which receives support from the Ontario Ministry of Health and the Ministry of Long-Term Care. Dr. Shuldiner received a Canadian Institutes of Health Research Health System Impact Postdoctoral Fellowship in support of the work. Dr. Yan disclosed no relevant financial relationships.

PIK3CA-related overgrowth spectrum (PROS) encompasses a set of rare disorders caused by pathogenic variants in the phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) gene. Under normal circumstances, this pathway is activated by the stimulation of tyrosine kinase receptors that leads to tightly regulated cell growth, proliferation, and migration. However, in PROS, pathogenic variants in the PI3KCA gene lead to an abnormal accumulation of the enzyme at the cell membrane, resulting in persistent activation of the PI3K/AKT/mTOR pathway and dysregulated cell overgrowth.

Excessive cell growth and proliferation leads to the overgrowth of tissues and organs characteristically seen in PROS. Because PIK3CA pathogenic variants are not present in every cell, only certain areas of the body are affected by overgrowth; these can range from isolated digits to whole limbs, the trunk, or one or more tissues or organs.

The diagnosis of PROS is typically confirmed through genetic testing of the PIK3CA gene, which can identify the specific pathogenic variants responsible for the disorder.

Here are five things to know about PROS.

1. PROS comprises a heterogeneous group of rare congenital diseases.

PROS is a term used to describe a group of rare congenital disorders that are characterized by abnormal, segmental, or lateralized growth of various body tissues and regions. These disorders are linked by a common cause: mosaic pathogenic gain-of-function variants in the PIK3CA gene. The genetic pathogenic variants that cause these disorders are not passed down from parent to child but instead result from changes to genes during embryonic development.

PROS encompasses a range of clinical entities, each with its own set of characteristics but sharing phenotypic similarities. These clinical entities include:

• Fibroadipose hyperplasia (also called fibroadipose overgrowth)
• CLOVES syndrome (congenital lipomatosis overgrowth, vascular malformations, epidermal nevi, and scoliosis/skeletal or spinal abnormalities)
• Klippel-Trenaunay syndrome
• Megalencephaly-capillary malformation (MCAP) syndrome
• Hemihyperplasia‐multiple lipomatosis syndrome
• Dysplastic megalencephaly, hemimegalencephaly, and focal cortical dysplasia
• Facial infiltrating lipomatosis (a congenital disorder that causes overgrowth of one side of the face)
• Macrodactyly
• Isolated tissue dysplasia-overgrowth phenotypes: lymphatic malformations, vascular malformations, venous malformations, lipomatosis
• CLAPO syndrome (capillary malformation of the lower lip, lymphatic malformation of the face and neck, asymmetry, and partial/generalized overgrowth)

The global epidemiologic characteristics of PROS are not well documented, but it is estimated that each of these conditions individually has a prevalence rate of fewer than 1 case per million population, and the collective prevalence of PROS-related syndromes is 14 cases per million population. Owing to its low prevalence and the variety of diseases it encompasses, PROS is classified as a rare disease.

2. PROS diseases have specific phenotypic features with common characteristics that result in overlapping phenomena.

The severity of clinical presentation varies in patients with PROS; some have tissue-specific distribution whereas others are more pleiotropic. In general, this condition is marked by segmental overgrowth of multiple tissues, including:

• Organs and other tissues: Excessive and asymmetric overgrowth can affect the skin, bones, muscles, and other structures, leading to disfigurement and functional impairments. The overgrowth typically follows a distal to proximal pattern, mostly unilateral and affecting the lower limbs.
• Brain: Enlargement of specific structures, including ventriculomegaly, a thick corpus callosum, or cerebellar tonsillar ectopia, can cause megalencephaly, which can lead to developmental delay, seizures, cortical dysplasia, and/or hydrocephalus.
• Vasculature: Capillary, venous, arteriovenous, and lymphatic malformations are common and occur in about 43% of patients. These abnormalities can contribute to additional complications, including swelling, pain, and increased risk for bleeding.
• Skin: Thickened epidermal nevi and pigmentary anomalies, such as hyperpigmentation or hypopigmentation, are common. These skin manifestations can be early signs of PROS and may aid in diagnosis.
• Skeletal system: Anomalies can include polydactyly, macrodactyly, macrodontia, and scoliosis or other spinal abnormalities.
• Lipomatosis overgrowth: This can occur with or without regional reduction of adipose tissue on the trunk and limbs.
• Lymphatic system: Isolated malformations may include dilated vascular channels lined by lymphatic endothelial cells, which may lead to fluid-filled cysts that usually grow proportionally with the growth of the affected person and may cause pain or significant morbidity if they are infiltrative.

3. Treatment for a PROS disorder may involve targeted options, surgical interventions, and supportive care.

Historically, treatment for overgrowth syndromes such as PROS primarily involved conservative management, focusing on addressing complications through surgical excision, orthopedic surgery, sclerotherapy, embolization, and compressive therapies. However, these strategies often proved insufficient, and patients frequently experienced relapse and progression of the condition. Indeed, PROS is a complex condition that requires a multifaceted treatment approach.

The discovery of the PIK3/AKT/mTOR activation pathway in these syndromes marked a significant therapeutic breakthrough. Targeted therapies, such as the use of mTOR inhibitors like sirolimus, have shown benefits in treating venous and lymphatic malformations in patients with PROS. More recently, a selective PIK3CA inhibitor, alpelisib, has been approved. This drug has demonstrated remarkable improvements in patients with various PROS phenotypes, including reductions in capillary malformations; cessation of chronic gastrointestinal bleeding; and improvements in scoliosis and cognitive function, particularly in patients with MCAP syndrome.

Supportive care is also a critical component of managing PROS. This includes surgical interventions for significant overgrowth, orthopedic care for scoliosis and leg-length discrepancies, and neurosurgical interventions for neurologic complications such as obstructive hydrocephalus and epilepsy. Vascular and lymphatic malformations may be treated with sclerotherapy, laser therapy, or medications such as sirolimus. Additionally, routine treatment for associated conditions such as cardiac and renal abnormalities, intellectual disabilities, polydactyly, coagulopathy, and hypothyroidism is essential. For those with pain, identifying and treating the underlying cause is crucial. In cases of severe persistent hypoglycemia, ongoing treatment, which may include cornstarch administration, is necessary. Owing to the complexity and varied manifestations of PROS, specialized multidisciplinary care for diagnosis, follow-up, and optimal management is recommended.

4. PROS is a heterogeneous condition, and the clinical presentation can vary widely among affected individuals.

PROS is a complex and heterogeneous condition characterized by a wide range of clinical presentations, reflecting the diversity of affected tissues and the extent of overgrowth. Phenotypes within PROS are diverse and can range from a single lesion (ie, solitary macrodactyly) to systemic diseases (ie, Klippel-Trenaunay syndrome and CLOVES syndrome).

This heterogeneity is primarily due to the timing of the onset of the somatic causative PIK3CA pathogenic variants during embryonic and fetal development, influencing the degree of mosaicism and the combination of tissues involved (eg, neural progenitor cell pathogenic variants can lead to postnatal megalencephaly and hydrocephalus). Moreover, different gain-of-function variants in PIK3CA lead to varying levels of hyperactivation of the PI3K/AKT/mTOR pathway, resulting in diverse severity of abnormal proliferation of mesodermal and ectodermal tissues from embryogenesis onward.

This spectrum of symptoms underscores the complexity and variability of PROS, necessitating a tailored approach to diagnosis and management.

5. Regular surveillance is crucial for the effective management of PROS

Comprehensive and regular monitoring is essential to address the diverse and evolving clinical manifestations of PROS. During each medical visit, it is essential to measure growth parameters, including head circumference and the length of arms, hands, legs, and feet. This assessment helps identify any new neurologic symptoms such as seizures, changes in muscle tone, or signs of Chiari malformation.

Additionally, monitoring the patient’s developmental progress, behavior, and motor skills is vital. Clinical assessments for conditions like scoliosis and abdominal examinations for organomegaly or abdominal masses are also recommended.

Imaging plays a significant role in the ongoing evaluation of PROS. Serial head MRI is advised, with the frequency depending on the initial severity of findings and the degree of brain maturation. For patients with central nervous system overgrowth or dysplasia, brain MRI every 6 months until age 2 years, followed by annual scans until age 8 years, is recommended to monitor for progressive hydrocephalus and Chiari malformation.

Further specialized assessments may be required based on individual clinical indications. These include monitoring of vascular and lymphatic malformations, radiographs of limbs in cases of limb overgrowth, and follow-up ultrasonography or MRI for truncal overgrowth. Spinal MRI is necessary for patients with scoliosis or spinal deformities.

In cases of persistent hypoglycemia, particularly those needing ongoing treatment, blood glucose monitoring and evaluation of the hypothalamic-pituitary-adrenal axis are important.

Postsurgical patients, especially those with the CLOVES phenotype or vascular malformations, should have a hematology consultation to assess thrombosis and coagulopathy risks. The use of renal ultrasonography every 3 months until age 8 years is suggested for tumor screening, such as Wilms tumor, although this practice is somewhat controversial.

These comprehensive and tailored approaches are critical in managing the complex and varied aspects of PROS, ensuring optimal care and monitoring for affected individuals.

PIK3CA-related overgrowth spectrum (PROS) encompasses a set of rare disorders caused by pathogenic variants in the phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) gene. Under normal circumstances, this pathway is activated by the stimulation of tyrosine kinase receptors that leads to tightly regulated cell growth, proliferation, and migration. However, in PROS, pathogenic variants in the PI3KCA gene lead to an abnormal accumulation of the enzyme at the cell membrane, resulting in persistent activation of the PI3K/AKT/mTOR pathway and dysregulated cell overgrowth.

Excessive cell growth and proliferation leads to the overgrowth of tissues and organs characteristically seen in PROS. Because PIK3CA pathogenic variants are not present in every cell, only certain areas of the body are affected by overgrowth; these can range from isolated digits to whole limbs, the trunk, or one or more tissues or organs.

The diagnosis of PROS is typically confirmed through genetic testing of the PIK3CA gene, which can identify the specific pathogenic variants responsible for the disorder.

Here are five things to know about PROS.

1. PROS comprises a heterogeneous group of rare congenital diseases.

PROS is a term used to describe a group of rare congenital disorders that are characterized by abnormal, segmental, or lateralized growth of various body tissues and regions. These disorders are linked by a common cause: mosaic pathogenic gain-of-function variants in the PIK3CA gene. The genetic pathogenic variants that cause these disorders are not passed down from parent to child but instead result from changes to genes during embryonic development.

PROS encompasses a range of clinical entities, each with its own set of characteristics but sharing phenotypic similarities. These clinical entities include:

• Fibroadipose hyperplasia (also called fibroadipose overgrowth)
• CLOVES syndrome (congenital lipomatosis overgrowth, vascular malformations, epidermal nevi, and scoliosis/skeletal or spinal abnormalities)
• Klippel-Trenaunay syndrome
• Megalencephaly-capillary malformation (MCAP) syndrome
• Hemihyperplasia‐multiple lipomatosis syndrome
• Dysplastic megalencephaly, hemimegalencephaly, and focal cortical dysplasia
• Facial infiltrating lipomatosis (a congenital disorder that causes overgrowth of one side of the face)
• Macrodactyly
• Isolated tissue dysplasia-overgrowth phenotypes: lymphatic malformations, vascular malformations, venous malformations, lipomatosis
• CLAPO syndrome (capillary malformation of the lower lip, lymphatic malformation of the face and neck, asymmetry, and partial/generalized overgrowth)

The global epidemiologic characteristics of PROS are not well documented, but it is estimated that each of these conditions individually has a prevalence rate of fewer than 1 case per million population, and the collective prevalence of PROS-related syndromes is 14 cases per million population. Owing to its low prevalence and the variety of diseases it encompasses, PROS is classified as a rare disease.

2. PROS diseases have specific phenotypic features with common characteristics that result in overlapping phenomena.

The severity of clinical presentation varies in patients with PROS; some have tissue-specific distribution whereas others are more pleiotropic. In general, this condition is marked by segmental overgrowth of multiple tissues, including:

• Organs and other tissues: Excessive and asymmetric overgrowth can affect the skin, bones, muscles, and other structures, leading to disfigurement and functional impairments. The overgrowth typically follows a distal to proximal pattern, mostly unilateral and affecting the lower limbs.
• Brain: Enlargement of specific structures, including ventriculomegaly, a thick corpus callosum, or cerebellar tonsillar ectopia, can cause megalencephaly, which can lead to developmental delay, seizures, cortical dysplasia, and/or hydrocephalus.
• Vasculature: Capillary, venous, arteriovenous, and lymphatic malformations are common and occur in about 43% of patients. These abnormalities can contribute to additional complications, including swelling, pain, and increased risk for bleeding.
• Skin: Thickened epidermal nevi and pigmentary anomalies, such as hyperpigmentation or hypopigmentation, are common. These skin manifestations can be early signs of PROS and may aid in diagnosis.
• Skeletal system: Anomalies can include polydactyly, macrodactyly, macrodontia, and scoliosis or other spinal abnormalities.
• Lipomatosis overgrowth: This can occur with or without regional reduction of adipose tissue on the trunk and limbs.
• Lymphatic system: Isolated malformations may include dilated vascular channels lined by lymphatic endothelial cells, which may lead to fluid-filled cysts that usually grow proportionally with the growth of the affected person and may cause pain or significant morbidity if they are infiltrative.

3. Treatment for a PROS disorder may involve targeted options, surgical interventions, and supportive care.

Historically, treatment for overgrowth syndromes such as PROS primarily involved conservative management, focusing on addressing complications through surgical excision, orthopedic surgery, sclerotherapy, embolization, and compressive therapies. However, these strategies often proved insufficient, and patients frequently experienced relapse and progression of the condition. Indeed, PROS is a complex condition that requires a multifaceted treatment approach.

The discovery of the PIK3/AKT/mTOR activation pathway in these syndromes marked a significant therapeutic breakthrough. Targeted therapies, such as the use of mTOR inhibitors like sirolimus, have shown benefits in treating venous and lymphatic malformations in patients with PROS. More recently, a selective PIK3CA inhibitor, alpelisib, has been approved. This drug has demonstrated remarkable improvements in patients with various PROS phenotypes, including reductions in capillary malformations; cessation of chronic gastrointestinal bleeding; and improvements in scoliosis and cognitive function, particularly in patients with MCAP syndrome.

Supportive care is also a critical component of managing PROS. This includes surgical interventions for significant overgrowth, orthopedic care for scoliosis and leg-length discrepancies, and neurosurgical interventions for neurologic complications such as obstructive hydrocephalus and epilepsy. Vascular and lymphatic malformations may be treated with sclerotherapy, laser therapy, or medications such as sirolimus. Additionally, routine treatment for associated conditions such as cardiac and renal abnormalities, intellectual disabilities, polydactyly, coagulopathy, and hypothyroidism is essential. For those with pain, identifying and treating the underlying cause is crucial. In cases of severe persistent hypoglycemia, ongoing treatment, which may include cornstarch administration, is necessary. Owing to the complexity and varied manifestations of PROS, specialized multidisciplinary care for diagnosis, follow-up, and optimal management is recommended.

4. PROS is a heterogeneous condition, and the clinical presentation can vary widely among affected individuals.

PROS is a complex and heterogeneous condition characterized by a wide range of clinical presentations, reflecting the diversity of affected tissues and the extent of overgrowth. Phenotypes within PROS are diverse and can range from a single lesion (ie, solitary macrodactyly) to systemic diseases (ie, Klippel-Trenaunay syndrome and CLOVES syndrome).

Just over 2 months into 2024, measles cases in the United States aren’t looking great. 

The recent rise in cases across the U.S. is linked to unvaccinated travelers, lower than ideal vaccination rates, and misinformation, experts said. 

The Centers for Disease Control and Prevention has identified 45 cases of measles in 17 jurisdictions across the U.S. As of March 7, the federal health agency reported measles cases in Arizona, California, Florida, Georgia, Illinois, Indiana, Louisiana, Maryland, Michigan, Minnesota, Missouri, New Jersey, New York City, Ohio, Pennsylvania, Virginia, and Washington.

As for the 45 cases, “that’s almost as many as we had for the entire calendar year of 2023,” said Sarah Lim, MD, a medical specialist at the Minnesota Department of Health. “So we’re really not off to a great start.” (For context, there were 58 officially reported measles cases last year.) 

Chicago is having a measles outbreak — with eight cases reported so far. All but one case has been linked to a migrant child at a city shelter. Given the potential for rapid spread — measles is relatively rare here but potentially very serious — the CDC sent a team of experts to investigate and to help keep this outbreak from growing further.


 

Sometimes Deadly

About 30% of children have measles symptoms and about 25% end up hospitalized. Complications include diarrhea, a whole-body rash, ear infections that can lead to permanent deafness, and pneumonia. Pneumonia with measles can be so serious that 1 in 20 affected children die. Measles can also cause inflammation of the brain called encephalitis in about 1 in 1,000 children, sometimes causing epilepsy or permanent brain damage.

As with long COVID, some effects can last beyond the early infection. For example, measles “can wipe out immune memory that protects you against other bacterial and viral pathogens,” Dr. Lim said at a media briefing sponsored by the Infectious Diseases Society of America. This vulnerability to other infections can last up to 3 years after the early infection, she noted. 

Overall, measles kills between 1 and 3 people infected per thousand, mostly children.
 

Vaccine Misinformation Playing a Role

Vaccine misinformation is partly behind the uptick, and while many cases are mild, “this can be a devastating disease,” said Joshua Barocas, MD, associate professor of medicine in the divisions of General Internal Medicine and Infectious Diseases at the University of Colorado School of Medicine.

“I’m a parent myself. Parents are flooded with tons of information, some of that time being misinformation,” he said at the media briefing. “If you are a parent who’s been on the fence [about vaccination], now is the time, given the outbreak potential and the outbreaks that we’re seeing.” 

Vaccine misinformation “is about as old as vaccines themselves,” Dr. Lim said. Concerns about the MMR vaccine, which includes measles protection, are not new.

“It does seem to change periodically — new things bubble up, new ideas bubble up, and the problem is that it is like the old saying that ‘a lie can get halfway around the world before the truth can get its boots on.’ ” Social media helps to amplify vaccine misinformation, she said. 

“You don’t want to scare people unnecessarily — but reminding people what these childhood diseases really look like and what they do is incredibly important,” Dr. Lim said. “It’s so much easier to see stories about potential side effects of vaccines than it is to see stories about parents whose children were in intensive care for 2 weeks with pneumonia because of a severe case of measles.”

Dr. Barocas said misinformation is sometimes deliberate, sometimes not. Regardless, “our job as infectious disease physicians and public health professionals is not necessarily to put the counternarrative out there, but to continue to advocate for what we know works based on the best science and the best evidence.”

“And there is no reason to believe that vaccines are anything but helpful when it comes to preventing measles,” he noted. 
 

Lifelong Protection in Most Cases

The MMR vaccine, typically given as two doses in childhood, offers 93% and then 97% protection against the highly contagious virus. During the 2022-to-2023 school year, the measles vaccination rate among kindergarten children nationwide was 92%. That sounds like a high rate, Dr. Lim said, “but because measles is so contagious, vaccination rates need to be 95% or higher to contain transmission.”

One person with measles can infect anywhere from 12 to 18 other people, she said. When an infected person coughs or sneezes, tiny droplets spread through the air. “And if someone is unvaccinated and exposed, 9 times out of 10, that person will go on to develop the disease.” She said given the high transmission rate, measles often spreads within families to infect multiple children. 

If you know you’re not vaccinated but exposed, the advice is to get the measles shot as quickly as possible. “There is a recommendation to receive the MMR vaccine within 72 hours as post-exposure prophylaxis,” Dr. Lim said. “That’s a tight time window, but if you can do that, it reduces the risk of developing measles significantly.”

If you’re unsure or do not remember getting vaccinated against measles as a young child, your health care provider may be able to search state registries for an answer. If that doesn’t work, getting revaccinated with the MMR vaccine as an adult is an option. “There is no shame in getting caught up now,” Dr. Barocas said.

Dr. Lim agreed. “There is really no downside to getting additional doses.”

As for the 45 cases, “that’s almost as many as we had for the entire calendar year of 2023,” said Sarah Lim, MD, a medical specialist at the Minnesota Department of Health. “So we’re really not off to a great start.” (For context, there were 58 officially reported measles cases last year.) 

Chicago is having a measles outbreak — with eight cases reported so far. All but one case has been linked to a migrant child at a city shelter. Given the potential for rapid spread — measles is relatively rare here but potentially very serious — the CDC sent a team of experts to investigate and to help keep this outbreak from growing further.


 

Sometimes Deadly

About 30% of children have measles symptoms and about 25% end up hospitalized. Complications include diarrhea, a whole-body rash, ear infections that can lead to permanent deafness, and pneumonia. Pneumonia with measles can be so serious that 1 in 20 affected children die. Measles can also cause inflammation of the brain called encephalitis in about 1 in 1,000 children, sometimes causing epilepsy or permanent brain damage.

As with long COVID, some effects can last beyond the early infection. For example, measles “can wipe out immune memory that protects you against other bacterial and viral pathogens,” Dr. Lim said at a media briefing sponsored by the Infectious Diseases Society of America. This vulnerability to other infections can last up to 3 years after the early infection, she noted. 

Overall, measles kills between 1 and 3 people infected per thousand, mostly children.
 

Vaccine Misinformation Playing a Role

Vaccine misinformation is partly behind the uptick, and while many cases are mild, “this can be a devastating disease,” said Joshua Barocas, MD, associate professor of medicine in the divisions of General Internal Medicine and Infectious Diseases at the University of Colorado School of Medicine.

“I’m a parent myself. Parents are flooded with tons of information, some of that time being misinformation,” he said at the media briefing. “If you are a parent who’s been on the fence [about vaccination], now is the time, given the outbreak potential and the outbreaks that we’re seeing.” 

Vaccine misinformation “is about as old as vaccines themselves,” Dr. Lim said. Concerns about the MMR vaccine, which includes measles protection, are not new.

“It does seem to change periodically — new things bubble up, new ideas bubble up, and the problem is that it is like the old saying that ‘a lie can get halfway around the world before the truth can get its boots on.’ ” Social media helps to amplify vaccine misinformation, she said. 

“You don’t want to scare people unnecessarily — but reminding people what these childhood diseases really look like and what they do is incredibly important,” Dr. Lim said. “It’s so much easier to see stories about potential side effects of vaccines than it is to see stories about parents whose children were in intensive care for 2 weeks with pneumonia because of a severe case of measles.”

Dr. Barocas said misinformation is sometimes deliberate, sometimes not. Regardless, “our job as infectious disease physicians and public health professionals is not necessarily to put the counternarrative out there, but to continue to advocate for what we know works based on the best science and the best evidence.”

“And there is no reason to believe that vaccines are anything but helpful when it comes to preventing measles,” he noted. 
 

Lifelong Protection in Most Cases

The MMR vaccine, typically given as two doses in childhood, offers 93% and then 97% protection against the highly contagious virus. During the 2022-to-2023 school year, the measles vaccination rate among kindergarten children nationwide was 92%. That sounds like a high rate, Dr. Lim said, “but because measles is so contagious, vaccination rates need to be 95% or higher to contain transmission.”

One person with measles can infect anywhere from 12 to 18 other people, she said. When an infected person coughs or sneezes, tiny droplets spread through the air. “And if someone is unvaccinated and exposed, 9 times out of 10, that person will go on to develop the disease.” She said given the high transmission rate, measles often spreads within families to infect multiple children. 

If you know you’re not vaccinated but exposed, the advice is to get the measles shot as quickly as possible. “There is a recommendation to receive the MMR vaccine within 72 hours as post-exposure prophylaxis,” Dr. Lim said. “That’s a tight time window, but if you can do that, it reduces the risk of developing measles significantly.”

If you’re unsure or do not remember getting vaccinated against measles as a young child, your health care provider may be able to search state registries for an answer. If that doesn’t work, getting revaccinated with the MMR vaccine as an adult is an option. “There is no shame in getting caught up now,” Dr. Barocas said.

Dr. Lim agreed. “There is really no downside to getting additional doses.”

Nine days after the independent laboratory Valisure petitioned the Food and Drug Administration (FDA) to recall acne products with benzoyl peroxide (BP) because of the lab’s findings of extremely high levels of the carcinogen benzene, it published another report in Environmental Health Perspectives (EHP), on March 14, also warning about BP acne products.

The bottom line was the same: The laboratory, based in New Haven, Connecticut, said its analyses raise substantial concerns about the safety of BP-containing acne products currently on the market.

The lab’s results showed that the products can form over 800 times the conditionally restricted FDA concentration limit of 2 parts per million (ppm) of benzene, with both prescription and over-the-counter products affected.

“This is a problem of degradation, not contamination,” David Light, CEO and founder of Valisure, said in a telephone interview. BP can decompose into benzene, and exposure to benzene has been linked with a higher risk for leukemia and other blood cancers, according to the American Cancer Society.

In the wake of the findings, however, debate has erupted over the method and approach used by Valisure to test these products, with critics and companies contending that more “real-world” use data are needed. And the US Pharmacopeia (USP) is asking for full transparency about the testing methods.

In a March 8 statement, USP said the petition indicated that modified USP methods were used in the study, noting that “if changes are made to a USP method, complete validation data is necessary to demonstrate that a product meets USP standards.”

However, Valisure contended that drug products need to demonstrate stability over the entire life cycle, from shipment to continued use, emphasizing that constitutes the best “real-world” approach. It also defended the methodology it used.

The reports have led to a state of uncertainty about the use of BP products.

“Right now, we have more unknowns than anything else,” John Barbieri, MD, MBA, assistant professor of dermatology at Harvard Medical School and director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, said in a video posted on X and YouTube, summarizing the findings released by Valisure on March 6 and 14. He was not involved in the Valisure research.

Brigham and Women's Hospital

In a telephone interview, Dr. Barbieri said the report “needs to be taken seriously,” but he also believed the Valisure report is lacking information about testing under “real-world” conditions. He is calling for more information and more transparency about the data. What’s clear, Dr. Barbieri told this news organization, is that the findings about high benzene levels are not a manufacturing error. “It’s something to do with the molecule itself.”
 

Valisure’s Analyses

Valisure performed an initial analysis, using a method called gas chromatography-mass spectrometry, which is the FDA-preferred method for detecting benzene, Mr. Light said. It tested 175 acne products, 99 containing BP and 76 with other ingredients, such as salicylic acid. All the products without BP had no detectable benzene or values below 2 ppm, the FDA concentration limit for benzene.

Of the 99 BP products, 94 contained benzene without any elevated temperature incubation, according to Valisure. Using 50 °C (122 °F, the accepted pharmaceutical stability testing temperature) on 66 products, Valisure detected over 1500 ppm of benzene in two products, over 100 ppm in 17 products, and over 10 ppm in 42 products over an 18-day period.

The analysis confirmed, Valisure said in a press release and the petition, that a substantial amount of benzene can form in a BP product and leak outside the packaging into surrounding air.

The EHP paper, which includes authors from Valisure, reported that researchers took single lots of seven branded BP products, namely, Equate Beauty 2.5% BP cleansers, Neutrogena 10% BP cleanser, CVS Health 10% BP face wash, Walgreens 10% BP cream, Clean & Clear 10% cleanser, Equate Beauty 10% BP acne wash, and Proactiv 2.5% BP cleanser.

Using testing that involved gas chromatography-mass spectrometry, benzene was detected in all the BP products samples tested, and levels increased during incubation at body and shelf-life performance temperatures to more than 2 ppm. The authors concluded that the study “raises substantial concerns” about the safety of BP products currently on the market.
 

Methodology Debates

Two days after Valisure released its analysis on March 6, the USP reviewed the citizen’s petition filed by Valisure and called for more transparency around the testing methods.

“The petition referenced USP and indicated that modified USP methods and procedures were used in the study. The presence of unsafe levels of benzene should be taken seriously,” the statement said. The USP statement also noted that the Valisure analysis used modified USP methods and said that “if changes are made to a USP method, complete validation data is necessary to demonstrate that a product meets USP standards.”

In its statement, USP took issue with a practice known as accelerated thermal degradation, which it said Valisure used. USP said the approach involves raising the storage temperature of a product to higher than the temperature indicated on the label for the purpose of simulating degradation over a longer period. While the approach may be acceptable, USP said, the temperatures chosen may not be what is expected to happen to the products.

In response, Mr. Light of Valisure referenced guidance issued in August, 2020, from the FDA, stating that the method it used in the BP analysis can be used to detect impurities in hand sanitizers, including benzene. (In 2021, Valisure detected high levels of benzene in some hand sanitizers and asked the FDA to take action.)
 

Company Response

Among the companies that took issue with the report was Reckitt, which makes Clearasil, which contains BP. In a statement, the company said, in part: “The products and their ingredients are stable over the storage conditions described on their packaging which represent all reasonable and foreseeable conditions.” It said the findings presented by Valisure reflect “unrealistic scenarios rather than real-world conditions.”

The Personal Care Products Council, a national trade association that represents cosmetic and personal care product manufacturers, also took issue with the findings and the approach used to evaluate the products.
 

FDA and the Citizen’s Petition

The FDA accepted the petition, Mr. Light said, and gave it a docket number. “We’ll hopefully hear more soon” because the FDA is required to respond to a citizen’s petition within 180 days, he said.

“We generally don’t comment on pending citizens’ petitions,” an FDA spokesperson said in an email. “When we respond, we will respond directly to the petitioner and post the response in the designated agency public docket.”
 

Valisure’s Patent Application

Mr. Light and others have applied for a patent on methods of producing shelf-stable formulations to prevent degradation of BP to benzene.

“We saw the problem long before we had any sort of application,” Mr. Light said. The issue has been “known for decades.”
 

Role of BP Products for Acne

In the midst of uncertainty, “the first discussion is, do we want to use it?” Dr. Barbieri said in the interview. Some patients may want to avoid it altogether, until more data are available, including more verification of the findings, while others may be comfortable accepting the potential risk, he said.

“Benzoyl peroxide is one of our foundational acne treatments,” Dr. Barbieri said. In the American Academy of Dermatology updated guidelines on acne, published in January, 2024, strong recommendations were made for BP products, as well as topical retinoids, topical antibiotics, and oral doxycycline.

“When you take away BP, there’s no substitute for it,” Dr. Barbieri said. And if patients don’t get improvement with topicals, oral medications might be needed, and “these all have their own risks.”
 

In the Interim

Until more information is available, Dr. Barbieri is advising patients not to store the products at high temperatures or for a long time. Don’t keep the products past their expiration date, and perhaps keep products for a shorter time, “something like a month,” he said.

Those living in a hot climate might consider storing the products in the refrigerator, he said.

“We need more data from Valisure, from other groups that confirm their findings, and we need to hear from the FDA,” Dr. Barbieri said. “There’s a lot of uncertainty right now. But it’s important not to overreact.”

Dr. Barbieri had no relevant disclosures.
