Ruxolitinib for vitiligo: Experts share experiences from first year
.
The Food and Drug Administration approved the cream formulation of ruxolitinib (Opzelura), a JAK inhibitor, for repigmentation of nonsegmental vitiligo in July 2022 for people aged 12 years and older.
Raj Chovatiya, MD, PhD, assistant professor of dermatology at Northwestern University, Chicago, said that he likes to use ruxolitinib cream in combination with other treatments.
“In the real world with vitiligo patients, we’re oftentimes doing combinatorial therapy anyway. So phototherapy, specifically, narrow-band UVB, is something that we have a lot of clinical evidence for over the years, and it’s a modality that can combine with topical steroids and topical calcineurin inhibitors.”
He said trials to study combinations will yield better guidance on optimal use of ruxolitinib cream. “In general, vitiligo patients can really benefit from phototherapy,” he said in an interview. (Labeling recommends against combination with other JAK inhibitors, biologics, or potent immunosuppressants, such as azathioprine or cyclosporine.)
This first year has shown that ruxolitinib is an effective option, but counseling patients to expect slow improvement is important so that patients stick with it, he noted.
Documenting what treatments patients with vitiligo have used before is important, he said, as is counseling patients that ruxolitinib is approved only for use on up to 10% of a person’s body surface area. (Product labeling recommends that a thin layer be applied twice a day to affected areas up to 10% of body surface area.)
Ruxolitinib has brought a “louder voice” to vitiligo and has opened up options for patients with the disease, Dr. Chovatiya said. “Having the ability to topically treat people who have very extensive disease really gives us a lot more flexibility than we have had before.”
Good experiences with payers at safety-net hospital
Candrice R. Heath, MD, assistant professor of dermatology at Temple University, Philadelphia, said that real-world experience with topical ruxolitinib will be more evident after its been on the market for 18-24 months.
Dr. Heath said she, too, encourages use of narrow-band UVB phototherapy in conjunction with the treatment.
From an insurance reimbursement standpoint, she said that she is glad that there have been fewer hurdles in getting ruxolitinib to patients than she has experienced with other medications.
In her safety-net hospital, she told this news organization, she sees patients with many types of insurance, but most have Medicaid. “So, I’m always expecting the step therapies, denials, pushbacks, etc.,” she said. But the path has been smoother for ruxolitinib coverage, she noted.
Her colleagues are committed to documenting everything the patient has tried, she added, and that helps with prior authorization.
Dr. Heath said that pointing out to insurers that ruxolitinib is the only approved treatment for repigmentation helps facilitate coverage.
“The science is advancing, and I’m happy to be practicing during a time when we actually have something approved for vitiligo,” she said. But she pointed out that phototherapy often is not covered for vitiligo, “which is horrible, when it is readily approved for psoriasis and atopic dermatitis.”
To document progress, Dr. Heath said that she always takes photographs of her patients with vitiligo because “the pictures remind us how far we have come.”
Data spotlight success in adolescents
Data from two trials give a clinical picture of the drug’s safety and efficacy in younger patients.
Adolescents had particularly good results in the first year with ruxolitinib, according to pooled phase 3 data from TRuE-V1 and TRuE-V2, this news organization reported.
The findings, presented at the 25th World Congress of Dermatology in Singapore, indicate that more than half of the participants achieved at least a 50% improvement from baseline in the total Vitiligo Area Scoring Index (T-VASI50) at 52 weeks.
The percentages of young patients aged 12-17 years taking twice-daily ruxolitinib who achieved T-VASI 50 at weeks 12, 24, and 52 were 11.5%, 26.9%, and 57.7%, respectively. The corresponding percentages for all in the study population were 10.7%, 22.7%, and 44.4%, respectively.
At the meeting, the presenter, Julien Seneschal, MD, PhD, professor of dermatology and head of the vitiligo and pigmentary disorders clinic at the University of Bordeaux, France, said, “This suggests that younger patients can respond better to the treatment.” He noted, however, that there were few adolescents in the studies.
New excitement in the field
Daniel Gutierrez, MD, assistant professor of dermatology at New York University, said the treatment has brought new excitement to the field.
“Patients with vitiligo are very motivated to treat their disease,” he said, because it typically is on the face and other highly visual areas, which can affect their overall perception of self.
Previously, he noted in an interview, the only FDA-approved treatment was monobenzone, but that was for depigmentation rather than repigmentation.
Otherwise, treatments were being used off label, and patients were receiving compounded formulations that often weren’t covered by insurance and often had shorter shelf life.
He said that he still occasionally gets denials from payers who consider vitiligo a cosmetic condition.
“I’ve had more luck with insurance, at least in the New York State area.” He added that sometimes payers require use of a topical calcineurin inhibitor for about 12 weeks before they will cover ruxolitinib.
Dr. Gutierrez also recommends using phototherapy with topical ruxolitinib “because they work on slightly different pathways.”
When he starts patients on a new therapy such as ruxolitinib, he asks them to come back in 3 months, and often by then, progress is evident. Facial areas show the most response, he said, while hands and feet are less likely to show significant improvement.
He said that it’s important for physicians and patients to know that improvements can take weeks or months to be noticeable. “I tell patients not to give up,” he added.
Showing the patients pictures from the current appointment and comparing them with pictures from previous appointments can help them better understand their progress, he said.
Lead investigator adds observations
David Rosmarin, MD, chair of the department of dermatology at Indiana University, Indianapolis, was the lead investigator of the pivotal TruE-V1 and TruE-V2 trials for vitiligo. In that role, he has been treating vitiligo patients with topical ruxolitinib since 2015.
In an interview, he said that many patients “don’t hit their optimal results at 3 months, 6 months, even the year mark. With continued use, many can see continued benefit.”
Other patients, he said, don’t respond within the first 6 months but with continued use may eventually respond, he said.
“Unfortunately, we have no way of knowing, based on clinical characteristics or baseline demographics, whether a patient will be a delayed responder or not or an early responder,” Dr. Rosmarin added.
He provided several observations about people who have stopped taking the medication.
“When people stop,” he said, “some maintain their response, but some start to depigment again. Again, we have no way of predicting who will be in which category.”
He said that once patients have hit their desired response, he usually advises them to taper down to maybe twice a week or to stop treatment, but if they see any recurrence, they should start reusing the medicine.
“We have some patients who have gone 6 or 7 years now before they had a recurrence, but others may start to depigment again in 2 to 3 months,” Dr. Rosmarin said.
As for phototherapy, he said, the combination with topical ruxolitinib is being studied.
“We think the combination is synergistic and better than either alone, but we’re still waiting for data to prove that,” he said.
In his practice, he offers patients the option either to use just ruxolitinib cream or the combination early on. Many patients, because of convenience, say they’ll first try the cream to see if that works.
“The challenge with light [therapy] is that it can be very inconvenient,” he said. Patients have to live close to a phototherapy unit to receive therapy 2-3 times a week or have a phototherapy product in their home.
Next in the pipeline
Experts say the progress doesn’t stop with ruxolitinib cream. Current trials of several medications show there’s more to come for patients with vitiligo.
Dr. Chovatiya said that next up may be oral ritlecitinib (Litfulo), a JAK inhibitor that was approved for severe alopecia areata in June for people aged 12 years and older. Phase 2 results have been published for its use with vitiligo.
“This would be an oral medication that may be able to help people with much more extensive disease as far as vitiligo goes,” he said, adding that he expects approval for a vitiligo indication within a few years.
He pointed out that longer-term safety data will be available because it is already on the market for alopecia.
Upadacitinib (Rinvoq), an oral JAK inhibitor, is approved for atopic dermatitis but is being studied for vitiligo as well, he noted. “I’m very excited to see what that holds for patients as well,” Dr. Chovatiya said.
Dr. Gutierrez said that he is excited about oral JAK inhibitors but sees potential in finding new ways to transplant melanocytes into areas where there are none.
The pigmentation field has seen new energy since last year’s approval, he said, particularly among people of color.
“We have new options for vitiligo that were lacking compared with other conditions, such as atopic dermatitis and psoriasis,” he said. “Hopefully, there will be more promising breakthroughs.”
Dr. Rosmarin is the chief investigator for the pivotal trials that led to FDA approval of ruxolitinib. He disclosed ties with AbbVie, Abcuro, AltruBio, Amgen, Arena, Boehringer Ingelheim, Bristol-Meyers Squibb, Celgene, Concert, CSL Behring, Dermavant, Dermira, Galderma, Incyte, Janssen, Kyowa Kirin, Lilly, Merck, Novartis, Pfizer, Regeneron, Revolo Biotherapeutics, Sanofi, Sun Pharmaceuticals, UCB, and Viela Bio. Dr. Chovatiya disclosed ties with AbbVie, Arcutis, Arena, Argenx, Beiersdorf, Bristol-Myers Squibb, Dermavant, Eli Lilly, EPI Health, Incyte, LEO Pharma, L’Oréal, National Eczema Association, Pfizer, Regeneron, Sanofi, and UCB. Dr. Heath and Dr. Gutierrez report no relevant financial relationships.

Experts debate low-carb diets for people with diabetes
It’s an ongoing debate in the diabetes world: Is it ideal to consume a very-low-carbohydrate diet, or is it better to go with moderate amounts of healthful carbs?
At the annual scientific sessions of the American Diabetes Association, Carol F. Kirkpatrick, PhD, RDN, spoke first, arguing in favor of diets consisting of moderate, high-quality carbohydrates.
Dina Hafez Griauzde, MD, countered that very-low-carbohydrate diets are more beneficial for people with diabetes, primarily type 2 diabetes.
Both speakers based their arguments on published evidence but agreed in the end that discussion with patients about individual dietary preferences should play a major role in the ultimate decision.
Moderate-carbohydrate eating is best
Dr. Kirkpatrick began by explaining that definitions of “low carb” vary in the literature, which makes comparisons between studies difficult. On the basis of a 2019 review that she coauthored, “moderate” carbohydrate consumption was defined as a diet in which 26%-44% of total daily calories are from carbohydrates. “Low” carbohydrate consumption was defined as a diet in which 10%-25% of calories were from carbohydrates. Consuming less than 10% was defined as a very-low-carbohydrate diet (i.e., a ketogenic diet).
Across studies, she noted, the literature shows that within the first 6 months weight loss is typically greater with carbohydrate-restricted diets than with higher-carbohydrate diets, but that by 1 year and beyond weight loss is similar.
“That can be partly due to the difficulty in people maintaining that very severe dietary restriction, although ... we can all acknowledge that it’s difficult for patients to adhere to any dietary pattern, so for sure by 12 months, the difference in the weight loss is gone between the two,” said Dr. Kirkpatrick, of Midwest Biomedical Research, Pocatello, Idaho.
In a recent meta-analysis of 35 trials that examined the dose-dependent effects of carbohydrate restriction for patients with type 2 diabetes, there was a significant decrease in weight as carbohydrates were reduced. But by 12 months (17 trials), the greatest weight reduction was seen at 35% carbohydrate intake.
“It may just be that people were able to adhere to that moderate intake better,” she explained.
Regarding lipids, in her 2019 review and in several meta-analyses since, the effects on low-density lipoprotein cholesterol (LDL-C) varied. For some patients, adhering to a low-carb diet led to reductions in LDL-C, especially if the participants also lost weight, whereas in other patients, a low-carb diet led to an increase in LDL-C.
Either way, a high intake of saturated fatty acids is key to an increase in LDL-C, Dr. Kirkpatrick noted. “So, it’s important that, if a patient chooses to follow a very low carbohydrate diet or any kind of dietary pattern that restricts carbohydrate, that they replace the carbohydrate with unsaturated fat and not saturated fatty acid foods to avoid that increase in LDL-C.”
Generally, the evidence also shows that carbohydrate restriction typically leads to lower triglyceride levels and higher high-density lipoprotein (HDL) cholesterol levels. However, the same meta-analysis showed that the greatest reduction in LDL-C occurred at about 40% carbohydrate consumption.
Another recent meta-analysis showed that LDL-C rose significantly by an average 12.4 mg/dL with very-low-carb (3%-30%) diets, but only slightly, by 0.4 mg/dL, with moderate carb (40%-45%) intake.
Consuming very-low-carb diets did lead to greater reductions in triglycerides, compared with consuming moderate carb diets (23.9 mg/dL vs. 8.9 mg/dL).
“However, in terms of cardiovascular health, we are not entirely sure what that means. ... We have to look at the overall results in the presence of both triglyceride lowering as well as LDL cholesterol,” Dr. Kirkpatrick noted.
Carbohydrate restriction did consistently lead to lower hemoglobin A1c levels by an average of 0.4, 0.6, and 1.0 percentage points at 6 months for diets of 40%, 30%, and 15% carbohydrate, respectively. However, by 12 months, the effect had waned to 0.15, 0.2, and 0.4 A1c percentage points.
“Again, carbohydrate restriction, especially severe, is difficult for people to adhere to, and moderate carbohydrate intake would allow our patients to consume an appropriate amount of carbohydrate and still achieve improved glycemic control,” Dr. Kirkpatrick said.
Two large randomized controlled trials – PREDIMED and CORDIOPREV – examined the effects of the Mediterranean diet on cardiovascular disease prevention. Both showed a decrease in cardiovascular events with the Mediterranean diet, which involves consuming moderate amounts of carbohydrates.
“The Mediterranean dietary pattern has the strongest evidence for benefit, and it’s moderate in carbohydrates,” she concluded.
Very-low-carbohydrate eating is best
Dr. Griauzde was a last-minute replacement speaker for William S. Yancy Jr, MD, of Duke University, Durham, N.C., and presented his slides. She argued that consuming a very low carb diet improves glycemia and that it does not increase but possibly lowers cardiovascular risk.
She began by noting that prior to the discovery of insulin very-low-carb diets had been consumed for over a century to prolong life for people with type 1 diabetes.
“We have long recognized the deleterious role of carbohydrate in type 1 diabetes management, and we have increasingly recognized that role in the management of type 2 diabetes,” said Dr. Griauzde of the University of Michigan in Ann Arbor.
In a small study that compared maintaining a very-low-carb diet for 2 weeks with maintaining a high-carb diet for 2 weeks, total glucose areas under the curve were substantially lower (P < .05) during the low-carb phase, while A1c levels dropped from 7.3% to 6.8% (P = .006).
“We don’t see those outcomes with meds,” Dr. Griauzde noted, adding, “A diet very low in carbohydrates is one of the most potent tools we have to help our patients achieve glycemic control.”
Dr. Griauzde said that the carbohydrate-insulin model provides an explanation for why dietary carbohydrates are particularly obesogenic and metabolically harmful. That model contrasts with the energy balance model, which suggests that all calories are equal.
The rationale of the carbohydrate-insulin model is that dietary carbohydrate – either sugar or starch – raises serum glucose and insulin levels. A carbohydrate-restricted diet therefore reduces the dietary contribution to serum glucose, which then results in lower insulin levels. Insulin is a potent stimulator of lipogenesis (fat storage), and it is a potent inhibitor of lipolysis (the burning of fat). By lowering insulin levels, stored body fat is burned, serum ketone levels increase, and body weight is lowered.
This model suggests that, when insulin levels are chronically high because of excess carbohydrate consumption, circulating fuels are lowered, which leads to an increase in hunger and to overeating. This was demonstrated in a study that compared different levels of isocaloric glycemic index diets in 12 teenage boys with overweight or obesity. The higher-carbohydrate meals led to higher glucose and insulin levels and more food consumption.
In a systematic review of 13 trials of restricted-carbohydrate diets (< 45% carbohydrates) for adults with diabetes, the degree of improvement in A1c level correlated with the degree of carbohydrate restriction over 2-26 weeks (P = .013).
And in a network meta-analysis of 56 trials that compared nine diets among a total of 4,937 participants with type 2 diabetes, one conclusion was that “for reducing A1c, the low-carbohydrate diet was ranked as the best dietary approach (SUCRA: 84%), followed by the Mediterranean diet (80%), and Paleolithic diet (76%), compared with a control diet.”
Regarding the criticism that very-low-carbohydrate diets are high in saturated fat and therefore raise the risk of cardiovascular disease, Dr. Griauzde pointed to another meta-analysis of 21 prospective studies with more than 300,000 participants with 5-25 years of follow-up. In that analysis, the intake of saturated fat was not associated with an increased risk of cardiovascular disease or stroke.
Furthermore, a 12-week randomized controlled trial that involved 40 adults with overweight also suggested that a very-low-carb diet may be superior to a low-fat diet in improving aspects of the metabolic syndrome, including body mass index, lipid levels, and insulin sensitivity. Small LDL particles, which are more atherogenic than larger LDL particles, also decreased despite a threefold increase in saturated fat intake.
Rebuttals: Overall diet, patient preference matter
During the rebuttals, Dr. Kirkpatrick pointed out that large LDL particles are also atherogenic. In addition, she noted that the studies that showed that saturated fat isn’t associated with cardiovascular disease didn’t consider the macronutrients that replaced the saturated fat.
“It really is about increasing consumption of foods that we know are associated with cardiovascular benefit, including plant-based foods that are high quality and not refined carbohydrates ... and healthy protein sources. ... Hopefully we can step away from just looking at macronutrients and look at the total amount of food that people are choosing to eat.”
Importantly, Dr. Kirkpatrick said, patients need to be asked about their current dietary patterns and preferences. “Interventions should be patient centered and sensitive to cultural differences. Personalized lifestyle interventions increase the likelihood of success.”
Dr. Griauzde pointed out that newer antiobesity drugs can be added to any diet to decrease appetite and enhance adherence.
Dr. Griauzde also observed, “We can label a very-low-carbohydrate diet ‘extreme,’ but maybe, from the patient’s perspective, it’s extreme to take 200 units of insulin a day. If you can give them the opportunity to discontinue use of the insulin by following a very-low-carbohydrate dietary pattern, that is the opportunity that our patients deserve to have.”
But overall, she agreed with Dr. Kirkpatrick about individualizing any dietary approach: “We will never know from any of the trials that have been done or that will be done in the future what diet is best for an individual patient. ... Our job is to help our patients find the dietary approach that works best for them.”

It’s an ongoing debate in the diabetes world: Is it ideal to consume a very-low-carbohydrate diet, or is it better to go with moderate amounts of healthful carbs?
At the annual scientific sessions of the American Diabetes Association, Carol F. Kirkpatrick, PhD, RDN, spoke first, arguing in favor of diets consisting of moderate, high-quality carbohydrates.
Dina Hafez Griauzde, MD, countered that very-low-carbohydrate diets are more beneficial for people with diabetes, primarily type 2 diabetes.
Both speakers based their arguments on published evidence but agreed in the end that discussion with patients about individual dietary preferences should play a major role in the ultimate decision.
Moderate-carbohydrate eating is best
Dr. Kirkpatrick began by explaining that definitions of “low carb” vary in the literature, which makes comparisons between studies difficult. On the basis of a 2019 review that she coauthored, “moderate” carbohydrate consumption was defined as a diet in which 26%-44% of total daily calories are from carbohydrates. “Low” carbohydrate consumption was defined as a diet in which 10%-25% of calories were from carbohydrates. Consuming less than 10% was defined as a very-low-carbohydrate diet (i.e., a ketogenic diet).
Across studies, she noted, the literature shows that within the first 6 months weight loss is typically greater with carbohydrate-restricted diets than with higher-carbohydrate diets, but that by 1 year and beyond weight loss is similar.
“That can be partly due to the difficulty in people maintaining that very severe dietary restriction, although ... we can all acknowledge that it’s difficult for patients to adhere to any dietary pattern, so for sure by 12 months, the difference in the weight loss is gone between the two,” said Dr. Kirkpatrick, of Midwest Biomedical Research, Pocatello, Idaho.
In a recent meta-analysis of 35 trials that examined the dose-dependent effects of carbohydrate restriction for patients with type 2 diabetes, there was a significant decrease in weight as carbohydrates were reduced. But by 12 months (17 trials), the greatest weight reduction was seen at 35% carbohydrate intake.
“It may just be that people were able to adhere to that moderate intake better,” she explained.
Regarding lipids, in her 2019 review and in several meta-analyses since, the effects on low-density lipoprotein cholesterol (LDL-C) varied. For some patients, adhering to a low-carb diet led to reductions in LDL-C, especially if the participants also lost weight, whereas in other patients, a low-carb diet led to an increase in LDL-C.
Either way, a high intake of saturated fatty acids is key to an increase in LDL-C, Dr. Kirkpatrick noted. “So, it’s important that, if a patient chooses to follow a very low carbohydrate diet or any kind of dietary pattern that restricts carbohydrate, that they replace the carbohydrate with unsaturated fat and not saturated fatty acid foods to avoid that increase in LDL-C.”

Weight loss linked to mortality risk in older women
Weight loss of at least 5% over a 3-year period was associated with significantly increased mortality in women at age 90, 95, and 100 years compared with those whose weight remained stable, based on data from more than 50,000 individuals.
Previous studies of later-life weight changes and mortality have yielded inconsistent results driven by considerations of weight loss intentionality, and data on older adults in particular are limited, wrote Aladdin H. Shadyab, PhD, of the University of California, San Diego, and colleagues.
In a study published in the Journals of Gerontology: Medical Sciences, the researchers reviewed data from the Women’s Health Initiative, a prospective study of factors affecting chronic disease development in postmenopausal women. The study population included 54,437 women who entered the WHI between 1993 and 1998 at ages 50-79 years. The mean baseline age was 69.8 years; 89.5% of the participants were White, 5.7% were Black, 2.7% were Asian, 2.5% were Hispanic/Latino, and the remaining 1.0% were multiracial, American Indian/Alaskan Native, Native Hawaiian/Other Pacific Islander, or unknown.
The primary outcomes were the associations of short-term (3-year) and long-term (10-year) weight changes with survival to ages 90, 95, and 100 years.
A total of 30,647 women survived to at least 90 years (56.3%).
Overall, women with a short-term weight loss of 5% or more of body weight were 33% less likely to survive to age 90 years, 35% less likely to survive to age 95 years, and 38% less likely to survive to age 100 years than were those whose weight remained stable (odds ratios, 0.67, 0.65, and 0.62, respectively).
The associations were stronger in cases of unintentional short-term weight loss. Intentional weight loss from baseline to year 3 was associated with 17% lower odds of survival to age 90 compared to stable weight (OR, 0.83), but unintentional weight loss was associated with 51% lower odds of survival to age 90 (OR, 0.49).
Similarly, women with 10-year weight loss of at least 5% were 40% less likely to survive to 90 years and 49% less likely to survive to 95 years (OR, 0.60 and OR, 0.51, respectively). The sample size was too small to assess the relation of 10-year weight loss with survival to 100 years, and intentionality was not assessed for 10-year weight changes.
By contrast, weight gain of at least 5% had no significant effect on survival to ages 90, 95, or 100 years, but stable weight over time increased the odds of living to ages 90 to 100 years by 1.2-fold to 2-fold compared to either intentional or unintentional weight loss of at least 5%.
The trends in results were similar across body weight categories (normal weight, overweight, and obese as defined by body mass index). Baseline age and smoking status had no significant effect on the results.
Some of the proportion of self-reported intentional weight loss in the study population may have been unintentional, the researchers wrote in their discussion.
“It is important to note that perceived intentionality of weight loss may be influenced by the many societal pressures to lose weight, especially among women, and therefore overestimate the behavioral changes underlying experienced weight loss in older adults,” they said.
The findings were limited by several factors including the potential for inaccurate self-reported weight loss intention, and the likelihood that the mean older age of the population at baseline (older than 60 years) meant that they were more likely to live longer regardless of weight changes, the researchers noted. Other limitations included the primarily White study population, and other residual confounding factors such as ill health that might drive weight loss, the researchers noted.
However, the results were strengthened by the large sample size and long follow-up period, and suggest that “blanket recommendations for weight loss in older women are unlikely to lead to better survival at advanced ages,” they concluded.
Data support weight monitoring
The investigators acknowledged that their data do not affect clinical recommendations for moderate weight loss in older women to improve health outcomes, especially in those with overweight or obesity, but instead “support close monitoring of the amount and speed of weight loss, particularly when unintentional, as an indicator of underlying poor health and predictor of decreased lifespan in older women.”
Neil Skolnik, MD, professor of family and community medicine at the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, agreed with this conclusion. The current study suggests that when older women lose a significant amount of weight unintentionally, it could be a sign of failing health, he said.
Weight gain or loss in old age is very different from weight issues in younger people, where clinicians may be encouraging weight loss to improve health outcomes, Dr. Skolnik said in an interview.
A key take-home message for clinicians, in addition to monitoring weight in older patients, is to emphasize nutrition for individuals in their 80s, 90s, and beyond, he said.
The study was supported by the National Heart, Lung, and Blood Institute. Dr. Shadyab had no financial conflicts to disclose. Dr. Skolnik had no financial conflicts to disclose and serves on the editorial advisory board of Family Practice News.

The primary outcomes were the associations of short-term (3-year) and long-term (10-year) weight changes with survival to ages 90, 95, and 100 years.
A total of 30,647 women survived to at least 90 years (56.3%).
Overall, women with a short-term weight loss of 5% or more of body weight were 33% less likely to survive to age 90 years, 35% less likely to survive to age 95 years, and 38% less likely to survive to age 100 years than were those whose weight remained stable (odds ratios, 0.67, 0.65, and 0.62, respectively).
The associations were stronger in cases of unintentional short-term weight loss. Intentional weight loss from baseline to year 3 was associated with 17% lower odds of survival to age 90 compared to stable weight (OR, 0.83), but unintentional weight loss was associated with 51% lower odds of survival to age 90 (OR, 0.49).
Similarly, women with 10-year weight loss of at least 5% were 40% less likely to survive to 90 years and 49% less likely to survive to 95 years (OR, 0.60 and OR, 0.51, respectively). The sample size was too small to assess the relation of 10-year weight loss with survival to 100 years, and intentionality was not assessed for 10-year weight changes.
By contrast, weight gain of at least 5% had no significant effect on survival to ages 90, 95, or 100 years, but stable weight over time increased the odds of living to ages 90 to 100 years by 1.2-fold to 2-fold compared to either intentional or unintentional weight loss of at least 5%.
The trends in results were similar across body weight categories (normal weight, overweight, and obese as defined by body mass index). Baseline age and smoking status had no significant effect on the results.
Some of the proportion of self-reported intentional weight loss in the study population may have been unintentional, the researchers wrote in their discussion.
“It is important to note that perceived intentionality of weight loss may be influenced by the many societal pressures to lose weight, especially among women, and therefore overestimate the behavioral changes underlying experienced weight loss in older adults,” they said.
The findings were limited by several factors including the potential for inaccurate self-reported weight loss intention, and the likelihood that the mean older age of the population at baseline (older than 60 years) meant that they were more likely to live longer regardless of weight changes, the researchers noted. Other limitations included the primarily White study population, and other residual confounding factors such as ill health that might drive weight loss, the researchers noted.
However, the results were strengthened by the large sample size and long follow-up period, and suggest that “blanket recommendations for weight loss in older women are unlikely to lead to better survival at advanced ages,” they concluded.
Data support weight monitoring
The investigators acknowledged that their data do not affect clinical recommendations for moderate weight loss in older women to improve health outcomes, especially in those with overweight or obesity, but instead “support close monitoring of the amount and speed of weight loss, particularly when unintentional, as an indicator of underlying poor health and predictor of decreased lifespan in older women.”
Neil Skolnik, MD, professor of family and community medicine at the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, agreed with this conclusion. The current study suggests that when older women lose a significant amount of weight unintentionally, it could be a sign of failing health, he said.
Weight gain or loss in old age is very different from weight issues in younger people, where clinicians may be encouraging weight loss to improve health outcomes, Dr. Skolnik said in an interview.
A key take-home message for clinicians, in addition to monitoring weight in older patients, is to emphasize nutrition for individuals in their 80s, 90s, and beyond, he said.
The study was supported by the National Heart, Lung, and Blood Institute. Dr. Shadyab had no financial conflicts to disclose. Dr. Skolnik had no financial conflicts to disclose and serves on the editorial advisory board of Family Practice News.
Weight loss of at least 5% over a 3-year period was associated with significantly increased mortality in women at age 90, 95, and 100 years compared with those whose weight remained stable, based on data from more than 50,000 individuals.
Previous studies of later-life weight changes and mortality have yielded inconsistent results driven by considerations of weight loss intentionality, and data on older adults in particular are limited, wrote Aladdin H. Shadyab, PhD, of the University of California, San Diego, and colleagues.
In a study published in the Journals of Gerontology: Medical Sciences, the researchers reviewed data from the Women’s Health Initiative, a prospective study of factors affecting chronic disease development in postmenopausal women. The study population included 54,437 women who entered the WHI between 1993 and 1998 at ages 50-79 years. The mean baseline age was 69.8 years; 89.5% of the participants were White, 5.7% were Black, 2.7% were Asian, 2.5% were Hispanic/Latino, and the remaining 1.0% were multiracial, American Indian/Alaskan Native, Native Hawaiian/Other Pacific Islander, or unknown.

Diabetes drug class appears to reduce recurrent gout flares
The glucose-lowering drug class sodium-glucose cotransporter 2 (SGLT2) inhibitors appear to reduce the risk for recurrent gout flares in people with gout and type 2 diabetes, and to lessen excess mortality in those individuals, compared with those who initiated other types of glucose-lowering medications, new data suggest.
Among nearly 6,000 adults with both type 2 diabetes and gout from a U.K. primary care database, initiation of SGLT2 inhibitor treatment was associated with 19% fewer recurrent gout flares and 29% lower mortality.
Moreover, unlike other urate-lowering therapies, there were no apparent transient increases in the risk of gout flares after initiating therapy, Jie Wei, PhD, of Health Management Center, Xiangya Hospital, Central South University, Changsha, China, and colleagues reported in JAMA Network Open.
These results are important because current management of gout is suboptimal. Many patients either don’t receive adequate urate-lowering therapies such as allopurinol or stop taking them, Dr. Wei and colleagues said.
In addition to lowering glucose, SGLT2 inhibitors also reduce the risk for major adverse cardiovascular events and all-cause mortality in people regardless of their diabetes status. Previous studies have also found that SGLT2 inhibitors reduce the risk for developing gout and of gout flares.
Asked to comment, gout specialist John D. FitzGerald, MD, PhD, clinical chief of rheumatology at the University of California, Los Angeles, said in an interview: “I think it’s a well-done paper, with a large dataset. I think it just reinforces the findings from the other papers. Mostly anything that lowers uric acid levels is going to lower recurrent gout attacks, so it all makes sense.”
However, while Dr. FitzGerald thinks the drug class is a good option for people with diabetes or cardiorenal indications for them who also have gout, he doesn’t envision it as first-line for most other patients with gout. “The current treatments are very effective. Allopurinol brings down uric acid levels by 5-7 points. There are patients who fail allopurinol, but those are less than 5%.”
The most common reason patients stop taking allopurinol is the frequent initial gout flare. But that’s preventable, Dr. FitzGerald said, either by titrating up slowly, or by adding colchicine along with it. “By going slowly, you can avoid that flare risk. I think that’s what’s going on with the SGLT2 inhibitor. It’s not a dramatic urate-lowering drug, but it is clinically meaningful. I think that’s what this paper is showing.”
But, he noted, “I think there are so many reasons to start the SGLT2 inhibitors that if somebody also has gout, all the better. And, if somebody is on the margin with diabetes and gout control and can’t go with allopurinol, it would be great to add for both conditions.”
Less gout recurrence, lower mortality
The retrospective study was conducted from Jan. 1, 2013, to March 31, 2022. Among 5,931 patients with both type 2 diabetes and gout, 1,548 (26.1%) initiated an SGLT2 inhibitor (dapagliflozin, empagliflozin, or canagliflozin), while 4,383 (73.9%) initiated treatment with other active comparators, mostly (92.6%) dipeptidyl peptidase–4 inhibitors.
Gout flares were identified in the charts for a total of 86% of the participants. The weighted incidence rates for the first recurrent flare were 32.4 versus 41.2 per 1,000 person-years in the SGLT2 inhibitor versus comparator groups, with a weighted absolute rate difference of –8.8/1,000 and weighted hazard ratio of 0.81, a significant difference.
All-cause mortality was 18.8 versus 24.9 per 1,000 person-years, respectively, giving an HR of 0.71 at 5-year follow-up.
Dr. FitzGerald, who chaired the American College of Rheumatology’s 2020 gout guidelines, said he anticipates that the SGLT2 inhibitors will be mentioned in the next update to the ACR’s now “living” guidelines, although he was not speaking on the organization’s behalf.
“We talk about losartan in the current [ACR guidelines], about its specific uric acid–lowering effect. Drugs can make uric acid worse or better. For example, thiazides make it higher. I think the SGLT2 [inhibitors] are important, but I don’t think they’re huge. The study is great, and I think the drugs are great, but I don’t think they will change the way gout is managed.”
This work was supported by grants from 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, and from the Natural Science Foundation of Hunan Province. Dr. Wei reported receiving grant funding from Xiangya Hospital Central South University Project Program of National Clinical Research Center for Geriatric Disorders and the Science and Technology Department of Hunan Province, the Natural Science Foundation of Hunan Province, during the conduct of the study. Dr. FitzGerald reported no relevant financial relationships.

NPs, PAs, and physicians hope to join doctors’ union in rare alliance
Advanced practice providers (APPs) such as nurse practitioners (NPs) and physician assistants (PAs) have long been at odds with doctor groups over scope of practice issues. But in a rare alliance, in late September. If successful, the Allina group will join the Doctors Council SEIU, Local 10MD.
The Allina health care providers share concerns about their working conditions, such as understaffing and inadequate resources, limited decision-making authority, and health systems valuing productivity and profit over patient care.
Although doctors and APPs have said that they generally work well together, the relationship has been strained in recent years as APPs argue for greater scope of practice. Meanwhile, physician groups, such as the American Medical Association, believe that APPs need more oversight.
An Allina union organizer, Britta V. Kasmarik, CNP, acknowledges the tension between physicians and APPs. But she said in an interview that the union effort helped bond this group of health care providers. “We share common goals of providing high-quality care for patients in a safe way, and we see the same things day in and day out with our patients.”
Matt Hoffman, MD, a primary care physician at Allina, told this news organization that APPs in his specialty perform the same job as doctors “and the working conditions are really identical. In our view, that means we should be unionizing together.”
The decision to hold a union vote follows similar action by nearly 150 Allina Mercy Hospital physicians in March. Allina Health appealed the vote.
In response to a New York Times investigation, the Minnesota Attorney General’s office began reviewing reports of aggressive billing practices and denied care at Allina Health.
The Allina Health system, which reports $4 billion in annual revenue, cut off nonemergency services to patients, including children, if their medical debt exceeded $4,500, according to the New York Times article. For Allina’s physicians and APPs, that meant leaving patients’ illnesses untreated.
Less than a week after the attorney general announced its investigation, the health system ended this practice.
In a prepared statement to this news organization, Allina Health said that its providers are “critical members of our teams. … We deeply value and share their commitment to providing high-quality care to our patients.”
The health system said it planned to make operational improvements, implement new communication tools, and provide additional well-being resources and enhanced employee benefits “to improve the provider experience.” In addition, it hoped to continue to “foster a culture of collaboration with all our employees.”
Having a union will allow health care providers to advocate for their patients and give health care providers more decision-making power instead of corporate leaders maintaining full authority, Ms. Kasmarik told this news organization.
Union organizers are also concerned with changes to the daily practice of medicine. “We don’t want to be spending our time doing paperwork and calling insurance companies and filling out forms,” said Dr. Hoffman. “We want to be in the exam room with a patient.”
The Allina providers organized after multiple requests to corporate managers failed to address their concerns. Their demands include increased staffing and help with nonclinical work so that clinicians can spend more time with their patients.
“What I’m really excited about is that we will be able to work with the other unionized groups to make change ... by being involved in health care policy at a state or national level,” Dr. Hoffman said. For example, that involvement might include challenging insurance company decisions.
Doctors Council bills itself as the largest union for attending physicians in the country, with 3,500 members, according to Joe Crane, national organizing director.
Despite an increase in union efforts since the pandemic, health care workers – particularly doctors – have been slow to join unions. Mr. Crane estimated that only about 3% of U.S. physicians are currently union members. He cited union campaigns in Massachusetts, New York, and Washington, DC. For comparison, a minority of advanced practice registered nurses (APRNs) (9%) report union membership, according to Medscape’s APRN compensation report last year.
Dr. Hoffman is confident the Allina health care providers will have enough votes to win the election to join the union. “We should have done this years ago.”

But she said in an interview that the union effort helped bond this group of health care providers. “We share common goals of providing high-quality care for patients in a safe way, and we see the same things day in and day out with our patients.”
Matt Hoffman, MD, a primary care physician at Allina, told this news organization that APPs in his specialty perform the same job as doctors “and the working conditions are really identical. In our view, that means we should be unionizing together.”
The decision to hold a union vote follows similar action by nearly 150 Allina Mercy Hospital physicians in March. Allina Health appealed the vote.
In response to a New York Times investigation, the Minnesota Attorney General’s office began reviewing reports of aggressive billing practices and denied care at Allina Health.
The Allina Health system, which reports $4 billion in annual revenue, cut off nonemergency services to patients, including children, if their medical debt exceeded $4,500, according to the New York Times article. For Allina’s physicians and APPs, that meant leaving patients’ illnesses untreated.
Less than a week after the attorney general announced its investigation, the health system ended this practice.
In a prepared statement to this news organization, Allina Health said that its providers are “critical members of our teams. … We deeply value and share their commitment to providing high-quality care to our patients.”
The health system said it planned to make operational improvements, implement new communication tools, and provide additional well-being resources and enhanced employee benefits “to improve the provider experience.” In addition, it hoped to continue to “foster a culture of collaboration with all our employees.”
Having a union will allow health care providers to advocate for their patients and give health care providers more decision-making power instead of corporate leaders maintaining full authority, Ms. Kasmarik told this news organization.
Union organizers are also concerned with changes to the daily practice of medicine. “We don’t want to be spending our time doing paperwork and calling insurance companies and filling out forms,” said Dr. Hoffman. “We want to be in the exam room with a patient.”
The Allina providers organized after multiple requests to corporate managers failed to address their concerns. Their demands include increased staffing and help with nonclinical work so that clinicians can spend more time with their patients.
“What I’m really excited about is that we will be able to work with the other unionized groups to make change ... by being involved in health care policy at a state or national level,” Dr. Hoffman said. For example, that involvement might include challenging insurance company decisions.
Doctors Council bills itself as the largest union for attending physicians in the country, with 3,500 members, according to Joe Crane, national organizing director.
Despite an increase in union efforts since the pandemic, health care workers – particularly doctors – have been slow to join unions. Mr. Crane estimated that only about 3% of U.S. physicians are currently union members. He cited union campaigns in Massachusetts, New York, and Washington, DC. For comparison, a minority of advanced practice registered nurses (APRNs) (9%) report union membership, according to Medscape’s APRN compensation report last year.
Dr. Hoffman is confident the Allina health care providers will have enough votes to win the election to join the union. “We should have done this years ago.”

These four GI conditions may predict Parkinson’s disease
Early detection of these conditions might help identify patients at risk for PD, potentially prompting preventive strategies, the researchers suggest.
The results of previous experimental studies by the team supported the Braak hypothesis, which states that idiopathic PD originates in the gut in a subset of patients. However, no previous study had investigated a broad range of gastrointestinal symptoms and syndromes that might occur prior to a PD diagnosis.
Given their preclinical work, the authors were not surprised to find that certain GI syndromes were specifically associated with PD, even when compared with Alzheimer’s disease (AD) and cerebrovascular disease (CVD), principal author Pankaj Jay Pasricha, MBBS, MD, of Mayo Clinic Arizona, Scottsdale, said in an interview. However, they were “impressed by the strength of the associations.”
“Experts have known for a very long time that constipation is a potential risk factor for PD, so this study adds to the list of GI conditions that could potentially be risk factors,” he said.
The study was published online in Gut.
Studies converge
To determine the incidence of GI syndromes and interventions preceding PD, the investigators performed a combined case-control and cohort study using a U.S.-based nationwide medical record network.
First, they compared 24,624 individuals with new-onset idiopathic PD with the same number of matched negative controls (NCs), as well as 19,046 people with AD and 23,942 with CVD to investigate the presence of preexisting GI conditions, which the researchers referred to as “exposures.” Overall, the mean age was about 70, and about half of those studied were women.
Eighteen conditions covering the entire GI tract were investigated. These included achalasia, dysphagia, gastroesophageal reflux disease, gastroparesis, functional dyspepsia, paralytic ileus, diarrhea, irritable bowel syndrome (IBS) with and without diarrhea, intestinal pseudo-obstruction, fecal incontinence, Crohn’s disease, ulcerative colitis, and microscopic colitis, as well as appendectomy and vagotomy.
All GI syndromes were significantly increased in the PD group, compared with NCs (odds ratio > 1). However, only preexisting dysphagia (OR, 3.58), gastroparesis (OR, 4.64), functional dyspepsia (OR, 3.39), intestinal pseudo-obstruction (OR, 3.01), diarrhea (OR, 2.85), constipation (OR, 3.32), IBS with constipation (OR, 4.11), IBS with diarrhea (OR, 4.31), IBS without diarrhea (OR, 3.53), and fecal incontinence (OR, 3.76) produced ORs that were numerically greater than the upper limit of the negative exposures.
In addition, only gastroparesis, dysphagia, IBS with constipation, IBS without diarrhea, and constipation were specific for PD, compared with the AD and CVD groups (OR > 1). After correction for false discovery rate, though, gastroparesis and constipation did not remain significantly different, compared with the AD and CVD groups.
Other preexisting GI conditions not only were significantly associated with PD but also showed strong associations with the AD and CVD groups.
To validate the case-control analyses, the team set up a complementary cohort study. Eighteen cohorts – each diagnosed with one of the GI conditions in the case-control analysis – were compared with their respective NC cohorts for the prospective risk of developing PD, AD, or CVD within 5 years.
Gastroparesis, dysphagia, IBS without diarrhea, and constipation showed specific associations with PD versus NCs, AD, and CVD in the cohort analysis. Their relative risks versus NCs were 2.43, 2.27, 1.17, and 2.38, respectively.
Functional dyspepsia, IBS with diarrhea, diarrhea, and fecal incontinence were not PD specific, but IBS with constipation and intestinal pseudo-obstruction showed PD specificity in both the case-control (OR, 4.11) and cohort analyses (RR, 1.84).
Appendectomy decreased the risk for PD in the cohort analysis (RR, 0.48), but neither inflammatory bowel disease nor vagotomy was associated with PD.
“This study is the first to establish substantial observational evidence that the clinical diagnosis of not only constipation but also dysphagia, gastroparesis, and IBS without diarrhea might specifically predict the development of PD, whereas other exposures were less specific,” the researchers wrote.
However, Dr. Pasricha said, “there is no need for alarm.” Clinicians should reassure patients that “the overall risk for developing PD is low. The overwhelming majority of patients with these GI conditions will never develop PD.”
His team will be doing experimental work on the biological mechanisms that might explain the current study’s findings. “In addition, the U.S. National Institutes of Health has issued a call for proposals to perform research in patients that could help understand these associations better,” he said.
Body or brain?
The Parkinson’s Foundation’s National Medical Advisor, Michael S. Okun, MD, called the study “fascinating.”
The findings “confirm many other studies showing that GI symptoms can precede a Parkinson’s disease diagnosis,” he said in an interview.
Although the study was designed to test the Braak hypothesis, “the dataset really cannot confirm or refute Braak pathology, which can only be accomplished with comparison to postmortem samples,” he added.
“The raging debate in the field of body-first versus brain-first Parkinson’s may be somewhat artificial, especially if we consider that Parkinson’s is not one disease,” Dr. Okun noted. “It will take clinical data, pathology, and the collaboration of many researchers to solve the puzzle.”
“The Foundation continues to monitor all the advancements in the ‘gut’ Parkinson field,” he said. “We do not recommend at this time changing the approach to clinical care based on this data.”
No funding or competing interests were declared. Dr. Okun declared no relevant disclosures.

One in five men carries high-risk HPV in international study
Findings from a meta-analysis of 65 studies conducted in 35 countries indicate that These estimates provide further weight to arguments in favor of vaccinating boys against HPV to prevent certain types of cancer.
“Our results support that sexually active men, regardless of age, are an important reservoir of HPV genital infection,” wrote the authors in The Lancet Global Health . “These estimates emphasize the importance of incorporating men into comprehensive HPV prevention strategies to reduce HPV-related morbidity and mortality in men and ultimately achieve elimination of cervical cancer and other HPV-related diseases.”
Literature review
HPV infection is the most common sexually transmitted viral infection worldwide. More than 200 HPV types can be transmitted sexually, and at least 12 types are oncogenic. Previous studies have shown that most sexually active men and women acquire at least one genital HPV infection during their lifetime.
Although most HPV infections are asymptomatic, they can lead to cancer. Indeed, HPV is involved in the development of cervical, vulval, and vaginal cancers, as well as oropharyngeal and anal cancers, which also affect the male population. More than 25% of cancers caused by HPV occur in men.
Despite these observations, fewer epidemiologic studies have assessed HPV infection in men than in women. To determine the prevalence of HPV infection in the male population, Laia Bruni, MD, MPH, PhD, an epidemiologist at the Catalan Institute of Oncology in Barcelona, and her colleagues collated data from 65 studies conducted in 35 countries pertaining to males older than 15 years.
In this literature review, the researchers selected studies that reported infection rates in males without HPV-related symptoms. Studies conducted exclusively in populations that were considered at increased risk for sexually transmitted infections (STIs) were excluded. Overall, the analysis included close to 45,000 men.
Prevalent HPV genotype
Testing for HPV was conducted on samples collected from the anus and genitals. The results show a global pooled prevalence of HPV infection in males older than 15 years of 31% for any HPV and 21% for HR-HPV. One of these viruses, HPV-16, was the most prevalent HPV genotype (5% prevalence).
HPV prevalence was highest among young adults. It stabilized and decreased from age 50 years. Between ages 25 and 29 years, 35% of men are infected with HPV. It should be noted that prevalence is already high in the youngest group, reaching 28% in males between the ages of 15 and 19 years. The variations are similar for HR-HPV infections.
This age-related change is different from rates in women. Among the female population, HPV prevalence peaks soon after first sexual activity and declines with age, with a slight rebound after ages 50–55 years (i.e., often after or around the time of menopause), wrote the researchers.
The results also show country- and region-based disparities. The pooled prevalence for any HPV was highest in Sub-Saharan Africa (37%), followed by Europe and Northern America (36%). The lowest prevalence was in East and Southeast Asia (15%). Here again, the trends are similar with high-risk HPV.
Preventive measures
“Our study draws attention to the high prevalence, ranging from 20% to 30% for HR-HPV in men across most regions, and the need for strengthening HPV prevention within overall STI control efforts,” wrote the authors.
“Future epidemiological studies are needed to monitor trends in prevalence in men, especially considering the roll-out of HPV vaccination in girls and young women and that many countries are beginning to vaccinate boys.”
In France, the HPV vaccination program was extended in 2021 to include all boys between the ages of 11 and 14 years (two-dose schedule), with a catch-up course in males up to age 19 years (three-dose schedule). This is the same vaccine program as for girls. It is also recommended for men up to age 26 years who have sex with other men.
The 2023 return to school will see the launch of a general vaccination campaign aimed at seventh-grade students, both boys and girls, with parental consent, to increase vaccine coverage. In 2021, vaccine uptake was 43.6% in girls between the ages of 15 and 18 years and scarcely 6% in boys, according to Public Health France.
Two vaccines are in use: the bivalent Cervarix vaccine, which is effective against HPV-16 and HPV-18, and the nonavalent Gardasil 9, which is effective against types 16, 18, 31, 33, 45, 52, and 58. Both provide protection against HPV-16, the type most common in men, which is responsible for more than half of cases of cervical cancer.

Five questions for COVID experts: How concerned should we be?
COVID-19 hospitalizations have been on the rise for weeks as summer nears its end, but how concerned should you be? SARS-CoV-2, the virus behind COVID, continues to evolve and surprise us. So COVID transmission, hospitalization, and death rates can be difficult to predict.
, especially now that testing and vaccinations are no longer free of charge.
Question 1: Are you expecting an end-of-summer COVID wave to be substantial?
Eric Topol, MD: “This wave won’t likely be substantial and could be more of a ‘wavelet.’ I’m not thinking that physicians are too concerned,” said Dr. Topol, founder and director of Scripps Research Translational Institute in La Jolla, Calif.
Thomas Gut, DO: “It’s always impossible to predict the severity of COVID waves. Although the virus has generally mutated in ways that favor easier transmission and milder illness, there have been a handful of surprising mutations that were more dangerous and deadly than the preceding strain,” said Dr. Gut, associate chair of medicine at Staten Island University Hospital/Northwell Health in New York.
Robert Atmar, MD: “I’ll start with the caveat that prognosticating for SARS-CoV-2 is a bit hazardous as we remain in unknown territory for some aspects of its epidemiology and evolution,” said Dr. Atmar, a professor of infectious diseases at Baylor College of Medicine in Houston. “It depends on your definition of substantial. We, at least in Houston, are already in the midst of a substantial surge in the burden of infection, at least as monitored through wastewater surveillance. The amount of virus in the wastewater already exceeds the peak level we saw last winter. That said, the increased infection burden has not translated into large increases in hospitalizations for COVID-19. Most persons hospitalized in our hospital are admitted with infection, not for the consequences of infection.”
Stuart Campbell Ray, MD: “It looks like there is a rise in infections, but the proportional rise in hospitalizations from severe cases is lower than in the past, suggesting that folks are protected by the immunity we’ve gained over the past few years through vaccination and prior infections. Of course, we should be thinking about how that applies to each of us – how recently we had a vaccine or COVID-19, and whether we might see more severe infections as immunity wanes,” said Dr. Ray, who is a professor of medicine in the division of infectious diseases at Johns Hopkins University in Baltimore.
Question 2: Is a return to masks or mask mandates coming this fall or winter?
Dr. Topol: “Mandating masks doesn’t work very well, but we may see wide use again if a descendant of [variant] BA.2.86 takes off.”
Dr. Gut: “It’s difficult to predict if there are any mask mandates returning at any point. Ever since the Omicron strains emerged, COVID has been relatively mild, compared to previous strains, so there probably won’t be any plan to start masking in public unless a more deadly strain appears.”
Dr. Atmar: “I do not think we will see a return to mask mandates this fall or winter for a variety of reasons. The primary one is that I don’t think the public will accept mask mandates. However, I think masking can continue to be an adjunctive measure to enhance protection from infection, along with booster vaccination.”
Dr. Ray: “Some people will choose to wear masks during a surge, particularly in situations like commuting where they don’t interfere with what they’re doing. They will wear masks particularly if they want to avoid infection due to concerns about others they care about, disruption of work or travel plans, or concerns about long-term consequences of repeated COVID-19.”
Question 3: Now that COVID testing and vaccinations are no longer free of charge, how might that affect their use?
Dr. Topol: “It was already low, and this will undoubtedly further compromise their uptake.”
Dr. Gut: “I do expect that testing will become less common now that tests are no longer free. I’m sure there will be a lower amount of detection in patients with milder or asymptomatic disease compared to what we had previously.”
Dr. Atmar: “If there are out-of-pocket costs for the SARS-CoV-2 vaccine, or if the administrative paperwork attached to getting a vaccine is increased, the uptake of SARS-CoV-2 vaccines will likely decrease. It will be important to communicate to the populations targeted for vaccination the potential benefits of such vaccination.”
Dr. Ray: “A challenge with COVID-19, all along, has been disparities in access to care, and this will be worse without public support for prevention and testing. This applies to everyone but is especially burdensome for those who are often marginalized in our health care system and society in general. I hope that we’ll find ways to ensure that people who need tests and vaccinations are able to access them, as good health is in everyone’s interest.”
Question 4: Will the new vaccines against COVID work for the currently circulating variants?
Dr. Topol: “The XBB.1.5 boosters will be out Sept. 14. They should help versus EG.5.1 and FL.1.5.1. The FL.1.5.1 variant is gaining now.”
Dr. Gut: “In the next several weeks, we expect the newer monovalent XBB-based vaccines to be offered that offer good protection against current circulating COVID variants along with the new Eris variant.”
Dr. Atmar: “The vaccines are expected to induce immune responses to the currently circulating variants, most of which are strains that evolved from the vaccine strain. The vaccine is expected to be most effective in preventing severe illness and will likely be less effective in preventing infection and mild illness.”
Dr. Ray: “Yes, the updated vaccine design has a spike antigen (XBB.1.5) nearly identical to the current dominant variant (EG.5). Even as variants change, the boosters stimulate B cells and T cells to help protect in a way that is safer than getting COVID-19 infection.”
Question 5: Is there anything we should watch out for regarding the BA.2.86 variant in particular?
Dr. Topol: “The scenario could change if there are new functional mutations added to it.”
Dr. Gut: “BA.2.86 is still fairly uncommon and does not have much data to directly make any informed guesses. However, in general, people that have been exposed to more recent mutations of the COVID virus have been shown to have more protection from newer upcoming mutations. It’s fair to guess that people that have not had recent infection from COVID, or have not had a recent booster, are at higher risk for being infected by any XBB- or BA.2-based strains.”
Dr. Atmar: BA.2.86 has been designated as a variant under monitoring. We will want to see whether it becomes more common and if there are any unexpected characteristics associated with infection by this variant.”
Dr. Ray: “It’s still rare, but it’s been seen in geographically dispersed places, so it’s got legs. The question is how effectively it will bypass some of the immunity we’ve gained. T cells are likely to remain protective, because they target so many parts of the virus that change more slowly, but antibodies from B cells to spike protein may have more trouble recognizing BA.2.86, whether those antibodies were made to a vaccine or a prior variant.”

How to optimize in-hospital antimicrobial prescribing?
Variability in antimicrobial prescribing among hospital-based physicians is not associated with patient characteristics or clinical outcomes, data suggest. The lowest level of such prescribing within each hospital could be considered a target for antimicrobial stewardship, according to the researchers.
In a multicenter study of 124 physicians responsible for more than 124,000 hospitalized patients, the difference in mean prescribing between the highest and lowest quartiles of prescription volume was 15.8 days of treatment per 100 patient-days.
Baseline patient characteristics were similar across the quartiles, and there were no differences in patient outcomes, including in-hospital deaths, hospital length of stay, intensive care unit transfer, and hospital readmission.
Although the investigators expected variation in prescribing, “what surprised us most was the limited association with any differences in clinical outcomes, particularly when it came to the amount of antimicrobials used,” study author Mark T. McIntyre, PharmD, pharmacotherapy specialist at the Sinai Health System in Toronto, told this news organization.
“Importantly, this is not a study that defines quality of care,” he said. “We looked at natural variation in practice and association with outcomes. So, I don’t want clinicians to think, ‘Well, I’m high, therefore I’m bad,’ or, ‘I’m low, therefore I’m good.’
“This is an early explanatory analysis that asks whether this is an opportunity to optimize prescribing in ways we hadn’t thought of before,” he said. “Now that we don’t have an association with higher or lower prescribing and outcomes, we can look at what else is driving that antimicrobial prescribing and what we can do about it. Comfort level, risk tolerance, and social, cultural, and contextual factors all likely play a role.”
The study was published online in the Canadian Medical Association Journal.
Antimicrobial reductions possible
The investigators conducted a retrospective cohort study using the General Medicine Inpatient Initiative database to assess physician-level volume and spectrum of antimicrobial prescribing in adult general medical wards. Four academic hospitals in Toronto were evaluated for the period 2010 to 2019.
The investigators stratified physicians into quartiles by hospital site on the basis of volume of antimicrobial prescribing (specifically, days of therapy per 100 patient-days and antimicrobial-free days) and antibacterial spectrum (modified spectrum score, which assigns a value to each antibacterial agent on the basis of its breadth of coverage).
They also examined potential differences between physician quartiles in patient characteristics, such as age, sex, the Laboratory-Based Acute Physiology Score, discharge diagnosis, and the Charlson Comorbidity Index.
Multilevel modeling allowed the investigators to evaluate the association between clinical outcomes and antimicrobial volume and spectrum.
The primary measure was days of therapy per 100 patient-days.
As noted, the cohort included 124 physicians who were responsible for 124,158 hospital admissions. The median physician-level volume of antimicrobial prescribing was 56.1 days of therapy per 100 patient-days. Patient characteristics were balanced across the quartiles of physician prescribing.
The difference in mean prescribing between physician quartile 4 and quartile 1 was 15.8 days of therapy per 100 patient-days, meaning the median physician in quartile 4 prescribed antimicrobials at a volume that was 30% higher than that of the median physician in quartile 1.
No significant differences were noted for any clinical outcome with regard to quartile of days of therapy, antimicrobial-free days, or modified spectrum score after adjustment for patient-level characteristics.
In addition, no significant differences in the case mix between quartile 4 and quartile 1 were found when the cohort was restricted to patients admitted and discharged by the same most responsible person, nor were differences found in an analysis that was restricted to those without a discharge diagnosis code of palliative care.
In-hospital mortality was higher among patients cared for by prescribers with higher modified spectrum scores (odds ratio, 1.13). “We still can’t fully explain this finding,” Dr. McIntyre acknowledged. “We only saw that in our primary analysis. When we did several sensitivity analyses, that finding didn’t appear.”
The authors concluded, “Ultimately, without discernible benefit in outcomes of patients of physicians who prescribe more frequently, less antimicrobial exposure may be possible, leading to lower risk of antimicrobial resistance.”
Decision-making support
Commenting on the study, Lawrence I. Kaplan, MD, section chief of general internal medicine and associate dean for interprofessional education at the Lewis Katz School of Medicine at Temple University in Philadelphia, said, “Trying to get to the lowest quartile would be a goal, and given that physician characteristics are involved, I think there needs to be much better training in clinical management decision-making: how you come about making a decision based on a diagnosis for a particular patient, in or out of the hospital.” Dr. Kaplan was not involved in the research.
“Clinical decision-making tools that can be plugged into the electronic health record can help,” he suggested. “The tools basically ask if a patient meets certain criteria and then might give a prompt that says, for example, ‘These symptoms are not consistent with bacterial sinusitis. The patient should be treated with decongestants, nasal steroids, et cetera, because antibiotics aren’t appropriate.’
“It’s a bit like checkbox medicine, which a lot of physicians bridle at,” he said. “But if it’s really based on evidence, I think that’s an appropriate use of evidence-based medicine.”
Dr. Kaplan said that more research is needed into the best way to get a physician or any provider to step back and say, “Is this the right decision?” or, “I’m doing this but I’m really on shaky ground. What am I missing?’” He noted that the Society for Medical Decision Making publishes research and resources in this area.
“I love the fact that the paper was authored by an interdisciplinary group,” Dr. Kaplan added. “A pharmacist embedded in the team can, for example, help with treatment decision-making and point out potential drug interactions that prescribers might not be aware of.
“We need to stop practicing medicine siloed, which is what we do a lot of ways, both in the hospital and out of the hospital, because it’s the path of least resistance,” Dr. Kaplan added. “But when we can say, ‘Hey, I have a question about this,’ be it to a computer or a colleague, I would argue that we come up with better care.”
No funding was provided for the study. Dr. McIntyre and Dr. Kaplan have disclosed no relevant financial relationships.

“This is an early explanatory analysis that asks whether this is an opportunity to optimize prescribing in ways we hadn’t thought of before,” he said. “Now that we don’t have an association with higher or lower prescribing and outcomes, we can look at what else is driving that antimicrobial prescribing and what we can do about it. Comfort level, risk tolerance, and social, cultural, and contextual factors all likely play a role.”
The study was published online in the Canadian Medical Association Journal.
Antimicrobial reductions possible
The investigators conducted a retrospective cohort study using the General Medicine Inpatient Initiative database to assess physician-level volume and spectrum of antimicrobial prescribing in adult general medical wards. Four academic hospitals in Toronto were evaluated for the period 2010 to 2019.
The investigators stratified physicians into quartiles by hospital site on the basis of volume of antimicrobial prescribing (specifically, days of therapy per 100 patient-days and antimicrobial-free days) and antibacterial spectrum (modified spectrum score, which assigns a value to each antibacterial agent on the basis of its breadth of coverage).
They also examined potential differences between physician quartiles in patient characteristics, such as age, sex, the Laboratory-Based Acute Physiology Score, discharge diagnosis, and the Charlson Comorbidity Index.
Multilevel modeling allowed the investigators to evaluate the association between clinical outcomes and antimicrobial volume and spectrum.
The primary measure was days of therapy per 100 patient-days.
As noted, the cohort included 124 physicians who were responsible for 124,158 hospital admissions. The median physician-level volume of antimicrobial prescribing was 56.1 days of therapy per 100 patient-days. Patient characteristics were balanced across the quartiles of physician prescribing.
The difference in mean prescribing between physician quartile 4 and quartile 1 was 15.8 days of therapy per 100 patient-days, meaning the median physician in quartile 4 prescribed antimicrobials at a volume that was 30% higher than that of the median physician in quartile 1.
No significant differences were noted for any clinical outcome with regard to quartile of days of therapy, antimicrobial-free days, or modified spectrum score after adjustment for patient-level characteristics.
In addition, no significant differences in the case mix between quartile 4 and quartile 1 were found when the cohort was restricted to patients admitted and discharged by the same most responsible person, nor were differences found in an analysis that was restricted to those without a discharge diagnosis code of palliative care.
In-hospital mortality was higher among patients cared for by prescribers with higher modified spectrum scores (odds ratio, 1.13). “We still can’t fully explain this finding,” Dr. McIntyre acknowledged. “We only saw that in our primary analysis. When we did several sensitivity analyses, that finding didn’t appear.”
The authors concluded, “Ultimately, without discernible benefit in outcomes of patients of physicians who prescribe more frequently, less antimicrobial exposure may be possible, leading to lower risk of antimicrobial resistance.”
Decision-making support
Commenting on the study, Lawrence I. Kaplan, MD, section chief of general internal medicine and associate dean for interprofessional education at the Lewis Katz School of Medicine at Temple University in Philadelphia, said, “Trying to get to the lowest quartile would be a goal, and given that physician characteristics are involved, I think there needs to be much better training in clinical management decision-making: how you come about making a decision based on a diagnosis for a particular patient, in or out of the hospital.” Dr. Kaplan was not involved in the research.
“Clinical decision-making tools that can be plugged into the electronic health record can help,” he suggested. “The tools basically ask if a patient meets certain criteria and then might give a prompt that says, for example, ‘These symptoms are not consistent with bacterial sinusitis. The patient should be treated with decongestants, nasal steroids, et cetera, because antibiotics aren’t appropriate.’
“It’s a bit like checkbox medicine, which a lot of physicians bridle at,” he said. “But if it’s really based on evidence, I think that’s an appropriate use of evidence-based medicine.”
Dr. Kaplan said that more research is needed into the best way to get a physician or any provider to step back and say, “Is this the right decision?” or, “I’m doing this but I’m really on shaky ground. What am I missing?’” He noted that the Society for Medical Decision Making publishes research and resources in this area.
“I love the fact that the paper was authored by an interdisciplinary group,” Dr. Kaplan added. “A pharmacist embedded in the team can, for example, help with treatment decision-making and point out potential drug interactions that prescribers might not be aware of.
“We need to stop practicing medicine siloed, which is what we do a lot of ways, both in the hospital and out of the hospital, because it’s the path of least resistance,” Dr. Kaplan added. “But when we can say, ‘Hey, I have a question about this,’ be it to a computer or a colleague, I would argue that we come up with better care.”
No funding was provided for the study. Dr. McIntyre and Dr. Kaplan have disclosed no relevant financial relationships.

FDA to step up oversight of cosmetics, assess ‘forever chemicals’
They are also preparing to assess potential risks of so-called forever chemicals in these products.
The Food and Drug Administration last year gained new authority over cosmetics when Congress passed the Modernization of Cosmetics Regulation Act of 2022 (MoCRA) by adding this bill to a December budget package.
“On average, consumers in the U.S. use six to 12 cosmetics products daily. But, until recently the FDA didn’t have the authority to require manufacturers to submit cosmetic product listings, including a list of ingredients used in these products, or register the facilities where they were produced,” Namandjé Bumpus, PhD, FDA’s chief scientist, said in a press release.
In the statement, the FDA announced the release of a draft guidance document that is intended to help companies comply with the transparency requirements slated to kick in this December. The agency is accepting comments on this draft guidance through Sept. 7.
“Later this year, registration and listing of cosmetic product facilities and products will become a requirement, making information about cosmetic products, including the ingredients used in products and the facilities where they are produced, readily available to the agency,” Dr. Bumpus said.
The products, according to the FDA statement, include makeup, nail polishes, shaving creams, other grooming products, perfumes, face and body cleansers, hair products, moisturizers, and other skin care items.
MoCRA “represents a sea change in how FDA regulates the cosmetics industry,” attorneys Frederick R. Ball, Alyson Walker Lotman, and Kelly A. Bonner, wrote in an article for the Food and Drug Law Institute published in spring 2023.
The FDA has called the MoCRA law “the most significant expansion” of its authority to regulate cosmetics since the Federal Food, Drug, and Cosmetic Act was passed in 1938.
The agency is in the process of expanding its staff to carry out newly authorized duties, including the tracking of adverse events. The FDA budget request for fiscal 2024, which begins Oct. 1, seeks $5 million for work needed to implement MoCRA.
PFAS, or ‘forever chemicals’
Some of the requested FDA funding is intended to prepare the agency to assess the use of per-and polyfluoroalkyl substances (PFAS) in cosmetics.
MoCRA sets a 3-year deadline for the FDA to issue an assessment of the use and potential risks of PFAS in cosmetics products. PFAS are sometimes added as ingredients in some cosmetic products, including lotions, cleansers, nail polish, shaving cream, foundation, lipstick, eyeliner, eyeshadow, and mascara, according to the FDA. Sometimes the presence of PFAS in cosmetics is unintentional and is the result of impurities in raw materials or is due to the breakdown of ingredients, the FDA said.
The FDA’s website says that so far, the available research doesn’t allow for “definitive conclusions about the potential health risks of PFAS in cosmetics.”
The Centers for Disease Control and Prevention has stated that research has suggested potential links between high levels of certain PFAS, in general, with increased cholesterol levels, changes in liver enzyme levels, increased risk of hypertension or preeclampsia in pregnant women, and increased risk of kidney or testicular cancer.
PFAS compounds often are used to resist grease, oil, water, and heat in industrial settings. They are used in thousands of products, from nonstick cookware to firefighting foams and protective gear, because they can reduce friction, according to a National Academies of Sciences, Engineering, and Medicine report on PFAS that was issued last year.
PFAS are known as “forever chemicals” because they contain a carbon-fluorine bond, which does not break naturally. Even when PFAS are transformed in the body, they can assume other forms of PFAS that preserve the troublesome carbon-fluorine bond. With PFAS, the human body is confronted with a substance it doesn’t have the tools to process.
This is in contrast to proteins and carbohydrates, which are in a sense prepackaged for relatively easy disassembly in the human body. Many of these compounds have weak links that enzymes and stomach acid can take apart, such as sulfur-to-sulfur (disulfide) bonds. That’s why protein-based biotech drugs are injected instead of administered as pills. The ultimate goal of this digestion is for the body to gain energy from these compounds.
But with PFAS, the body faces the challenge of carbon-fluorine bonds that are very hard to break down, and there is no payoff for these efforts, Graham F. Peaslee, PhD, professor of physics at the University of Notre Dame (Indiana), told this news organization.
“Nothing will naturally eat it because when you break the bond, it’s like eating celery,” he said. “You use more calories to eat the celery than you gain back from it.”
Interest from a U.S. senator
Dr. Peaslee was one of the authors of a 2021 article about PFAS in cosmetics that appeared in the journal Environmental Science and Technology Letters.
In the article, Dr. Peaslee and colleagues reported on their screening of 231 cosmetic products purchased in the United States and Canada using particle-induced gamma-ray emission spectroscopy. They found cases of undisclosed PFAS in cosmetic products. Foundations, mascaras, and lip products were noted as being especially problematic.
Sen. Susan Collins (R-ME) cited Dr. Peaslee’s article in a 2021 floor speech as she argued for having the FDA ban the intentional addition of PFAS to cosmetics.
“The findings of this study are particularly alarming, as many of these products are subject to direct human exposure,” Sen. Collins said. “For example, lipstick is often inadvertently ingested, and mascara is sometimes absorbed through tear ducts.”
In addition, workers at cosmetics plants may be exposed to PFAS and discarded cosmetics that have these compounds, which could potentially contaminate drinking water, Sen. Collins said. In 2021, she introduced legislation seeking a ban on PFAS that are intentionally added to cosmetics. That legislation did not advance through the Senate.
But the Senate Appropriations Committee, on which Sen. Collins is the ranking Republican, wants the FDA to keep a ban on PFAS in mind.
The Senate Agriculture Appropriations subcommittee, which oversees the FDA’s budget, raised the issue of PFAS and cosmetics in a June report. The FDA should develop a plan outlining research needed to inform “regulatory decision making, including potential development of a proposed rule to ban intentionally added PFAS substances in cosmetics,” the subcommittee said.
