Vasomotor symptoms the sudden rises in body temperature that affect about 75% of menopausal women, have drawn interest after the approval of a new oral drug and research linking hot flashes to Alzheimer’s, heart disease, and stroke. 

Now entering the discussion are researchers from the University of Massachusetts, Amherst, and Embr Labs (a Massachusetts Institute of Technology spinoff) who say they’ve developed a machine-learning algorithm that can predict a hot flash. 

Their idea is to combine this algorithm with a product called Embr Wave, a watch-like wearable that can emit coolness (or warmth) to the sensitive skin on the inside of the wrist, providing whole-body relief. The device, which sells for $299, is already touted as a way to manage menopausal hot flashes. 

But once the algorithm is added, the device will be able to “continuously monitor physiological signals – skin temperature, body temperature, sweating, activity level, or heart rate – and identify early indicators that a hot flash is building,” said Michael Busa, PhD, director of the Center for Human Health and Performance at UMass Amherst, who led the team that developed the algorithm.

That data would be sent to a computing platform in the cloud, where the algorithm can flag signs of an impending hot flash, Dr. Busa said. The device would automatically prompt cooling in less than a second, which could effectively stop the hot flash in its tracks or at least help to take the edge off. 
 

Exploring cooling therapy for hot flashes

“There is always tremendous interest in anything that is nonhormonal and effective in treatment of hot flashes,” said Karen Adams, MD, an ob.gyn. and director of the menopause and healthy aging program at Stanford (Calif.) University. (Dr. Adams was not involved in developing this technology.) 

Hormone therapy is the primary treatment, easing hot flashes in 3-4 weeks, Dr. Adams said. “But some women do not want to take estrogen, or should not due to medical contraindications.” 

Hormone therapy is generally not recommended for people with a history of breast cancer, blood clots, or diseases of their heart or blood vessels. Recent research presented at the annual meeting of the Menopause Society found that hormone therapy may not work as well in women with obesity. 

For nonhormonal treatments, the Food and Drug Administration cleared the oral med fezolinetant (Veozah) in May. Antidepressant medications can also be used as a first-line treatment in those who can’t take estrogen. Another oral drug, elinzanetant, is in late-stage clinical trials. 

But there has been little clinical investigation – only two small studies, Dr. Adams said – examining cooling therapy as a treatment for hot flashes. That’s something the makers of this device hope to change. 

“Despite the fact that seeking cooling relief is a woman’s immediate natural response to the onset of a hot flash, there is limited work done to understand the benefits of this natural therapy,” said Matthew Smith, PhD, chief technology officer at Embr Labs. “This is in part because the technology didn’t exist to deliver cooling in an immediate, reproducible manner.”

The algorithm’s performance has been benchmarked using data from women having hot flashes, Dr. Smith said. Results have been submitted for publication.

The Embr Wave has been shown to help menopausal women with hot flashes sleep better. It has also been tested as a therapy for hot flashes related to cancer treatment. 

But to truly evaluate the device as a treatment for hot flashes, it should be tested in randomized trials including a “sham treatment arm” – where some people get the real treatment while others get the sham treatment, Dr. Adams said. 

“Device studies tend to have high placebo response rates that can only be truly evaluated when there is a sham treatment in the study,” she said. “If such a device were shown to be safe and effective, we would absolutely recommend it. But we’re a long way from that.”

Prescriptions for semaglutide jumped 150% in the past year, with an 80% increase in prescriptions written per provider, new data suggest.

Among more than 350,000 prescribers in the nationwide DrFirst network between December 2022 and June 2023, prescriptions for the weight loss formulation Wegovy rose sixfold while those for Ozempic, the lower-dose version for treating type 2 diabetes, increased by 65%.

Before December 2022, prescribing for both semaglutide drug formulations had been relatively flat. Ozempic was approved in the United States for treating type 2 diabetes in 2017, and Wegovy for weight loss in 2021. Prescribing of oral type 2 diabetes drugs also rose during the study period but to a lesser degree.

General and family practice providers were the most frequent semaglutide providers, accounting for 30% of the total, followed by internists at 15%, endocrinologists at 4%, ob.gyns. at 2%, and pediatricians at 1%. Other specialists writing less than 1% of the prescriptions included cardiologists, emergency medicine physicians, hospitalists, psychiatrists, and surgeons.

“What I think is interesting is that in a relatively short period of time, primary care providers got comfortable with writing [prescriptions] for a drug that’s relatively new ... That isn’t always the case ... To me, it’s actually pretty telling that within a year or year and a half, the primary care field got very comfortable writing [prescriptions] for these [glucagon-like peptide 1 receptor agonists],” DrFirst chief medical officer Colin Banas, MD, said in an interview.

Asked to comment, S. Sethu K. Reddy, MD, president of the American Association of Clinical Endocrinologists, noted, “It is to be expected when there is an agent that not only lowers blood sugar levels but also may result in weight loss. These medications are packaged conveniently for a primary care physician to prescribe. There is enough awareness amongst the public in that the patients themselves often ask their physician about the medication.”

Moreover, Dr. Reddy noted, “there is clinical evidence that these medications not only improve diabetes control but also reduce the risk of cardiovascular events. The lack of cardiovascular safety data was a missing piece of the puzzle in the past. So, currently, if someone has type 2 diabetes and is at greater risk of cardiovascular disease, there is little controversy for the patient to receive GLP-1 analogs.”
 

Are patients actually getting the prescribed medications?

However, Sharon W. Lahiri, MD, of Wayne State University School of Medicine and Henry Ford Hospital, Detroit, pointed out that prescription data don’t equate to actual drug use. “It depends what type of insurance a person has. ... We write prescriptions on a daily basis for semaglutide. At least five or more come into our inbox every day saying it’s denied.”

Earlier this year, Dr. Lahiri co-authored results from a survey of 125 health care providers between February 9 and March 14, 2022, seeking to identify factors influencing medication choices and barriers to prescribing both GLP-1 agonists and sodium-glucose cotransporter 2 inhibitors. High cost and the need for prior authorizations were reported as the main barriers to prescribing drugs in these two classes, along with a lack of experience among some specialists.

Dr. Lahiri told this news organization that many insurers don’t cover Wegovy at all, or they mandate stepped-care paradigms in which the patient must enroll in behavior modification programs for a period of time or first try older, less expensive weight loss drugs such as phentermine, topiramate, or orlistat before they authorize coverage for Wegovy or even for the older weight-loss GLP-1 agonist drug Saxenda. “And then, they require you to document why the prior drugs didn’t work or couldn’t be tolerated.”

Moreover, Wegovy coverage is often time-limited, varying anywhere from 3 months to 2 years, and some insurers require a visit where the patient must have lost at least 5% of their body weight for coverage to continue.

Dr. Lahiri said recently she’s also encountered such “step” requirements when she’s tried to prescribe the “twincretin” Mounjaro for treating type 2 diabetes, where insurers will require trials of other GLP-1 agonists first. “So, it’s very complicated. I would say the barriers are definitely worse now. I don’t think the number of written prescriptions reflects that at all.”

Indeed, Dr. Banas noted, “more patients are going to pay out of pocket for Wegovy than for Ozempic if they have a diabetes indication.” And he added, “In my clinical observation, insurance coverage for obesity medication appears to be holding steady. I haven’t seen a massive increase in these drugs being covered for obesity per se, but I definitely see more coverage for diabetes use cases.”

The study was funded by DrFirst. Dr. Banas is an employee of DrFirst. Dr. Reddy and Dr. Lahiri have no disclosures.

With nutrient-stimulated hormone therapies for obesity in phase 3 trials, and activin-receptor inhibitors the next upcoming drug class, highly effective treatments for obesity are on the horizon.

“We are at a watershed [moment] brought on by the recent introduction of highly effective antiobesity medications,” Ania M. Jastreboff, MD, PhD, said in a lecture at the annual meeting of the Obesity Society.

Dr. Jastreboff, of Yale University and the Yale Center for Weight Management, New Haven, Conn., provided an overview of the many nutrient-stimulated hormone-based antiobesity therapies in late phases of development – including dual and triple therapies with glucagon-like peptide 1 receptor agonists (GLP-1 RAs), glucose-dependent insulinotropic polypeptide (GIP) agonists, glucagon, and amylin.

“I’ve shown you all of these agents that clearly produce substantial weight reduction,” she said. “The fact that these nutrient-stimulated, hormone-based therapies are not all the same is a good thing,” she stressed, because “it’s not likely that everyone will respond to each of these, and they are likely to respond differently.”

She then briefly touched on activin receptor inhibitors –”the next [medication] class that I think will be up and coming,” she speculated.

“Beyond (just) weight reduction,” Dr. Jastreboff concluded, clinicians “need to focus on optimizing health as we are treating obesity.” Clinicians need to consider the patient’s severity of obesity, overall health, and metabolic profile, and match the obesity treatment to the patient. They also need to consider the rate of weight reduction, potential bone loss, vitamin deficiencies, muscle loss and function, and side effects, and be mindful of affordability, bias, and stigma.
 

Looking forward to multiple options

W. Timothy Garvey, MD, of the University of Alabama at Birmingham, told this news organization that clinicians treating patients with obesity are looking forward to the decision from the Food and Drug Administration about tirzepatide (Mounjaro), expected by year’s end. Tirzepatide “is really the best medicine that we have for diabetes in terms of A1c control without much hypoglycemia,” he said, “and also the best medicine for treating obesity in patients with diabetes.”

A recent study found that people with type 2 diabetes who adhered to their tirzepatide regimen achieved a 15% weight loss from their baseline after 40-42 weeks.

Dr. Garvey added that he is looking forward to drugs in development such as survodutide (a GLP-1/glucagon agonist) and orforglipron (a small oral daily nonpeptide GLP-1 RA). “Orforglipron wouldn’t have to be refrigerated,” he noted, and it “could be cheaper to manufacture, might be preferred over subcutaneous medication by some people, and it showed pretty good efficacy in early studies.”

Retatrutide, a triple agonist (GLP-1/GIP/glucagon) and CagriSema (cagrilintide plus semaglutide) showed “pretty impressive weight loss in early studies,” Dr. Garvey said. “We’re optimistic.”

Also invited to comment, Sean Wharton, MD, PharmD, Wharton Medical Clinic and York University, Toronto, said that the recent developments in antiobesity medications are “so exciting that it’s difficult to make direct comments,” since “maybe there will be something bigger, or maybe something will go wrong with these molecules and we’ll have to back-step.”

Further studies are needed, he added, to determine outcomes in patients who reduce their intake to half or three-quarters of a dose, or who transition to intermittent therapy.
 

Nutrient-stimulated, hormone-based antiobesity medications

Here’s a status overview of the nutrient-stimulated hormone-based medications already approved and on the horizon:

Semaglutide. The GLP-1 RA semaglutide (Ozempic), was approved by the FDA for type 2 diabetes in 2017. In June 2021, the FDA approved the use of semaglutide (Wegovy) for obesity.

Topline results from the Semaglutide Effects on Heart Disease and Stroke in Patients with Overweight or Obesity (SELECT) cardiovascular outcome trial showed that in individuals with obesity without type 2 diabetes, semaglutide led to a 20% reduction in major cardiovascular events, Dr. Jastreboff noted, adding that full results will be presented at the American Heart Association meeting on Nov. 11.

Tirzepatide. In May 2022, the FDA approved tirzepatide (Mounjaro), a GIP/GLP-1RA, for type 2 diabetes, and a decision about the use of tirzepatide for obesity is expected by year’s end.

The full results of the phase 3 SURMOUNT-3 trial were presented at ObesityWeek (just after this session), as reported by this news organization.

And the full results of the phase 3 SURMOUNT-4 trial of tirzepatide for obesity were presented at the European Association for the Study of Diabetes meeting, Dr. Jastreboff noted. At 88 weeks, in the continued tirzepatide group, average weight reduction was 26%, absolute weight reduction was 62 pounds (28.1 kg), and > 50% of individuals achieved ≥ 25% weight loss.

The phase 3 SURMOUNT MMO trial of morbidity and mortality with tirzepatide in obesity is estimated to be completed in 2027.

Cagrilintide. In a phase 2 trial of the amylin analog cagrilintide in patients with obesity, more than half of participants lost at least 10% of their weight at 26 weeks.

CagriSema. In a phase 1b trial of the amylin analog/GLP-1 RA combination of cagrilintide/semaglutide (CagriSema), average weight reduction at 20 weeks was 17.1%. The estimated primary completion dates of phase 3 trials of CagriSema, REDEFINE 1 (obesity), REDEFINE 2  (obesity and type 2 diabetes), and REDEFINE 3 (obesity and established cardiovascular disease), are 2025, 2024, and 2027, respectively. 

Survodutide. Findings from a phase 2 trial of the glucagon/GLP-1 RA survodutide were presented at the American Diabetes Association (ADA) meeting in June. With 46 weeks of treatment, the average weight reduction was 18.7%, and up to 40% of participants lost at least 20% of their body weight.

Survodutide is being studied in the phase 3 SYNCHRONIZE trials.

Retatrutide. Phase 2 findings of 12-mg weekly of the GIP/GLP-1/glucagon triple hormone receptor agonist retatrutide were also presented at ADA. On average, at 48 weeks, the placebo group lost 2.1% of their weight and the retatrutide group lost 24.2% of their weight, with an average absolute reduction of 58 pounds (26.3 kg). At the highest dose (12 mg), 9 out of 10 individuals lost ≥ 10%, nearly two-thirds lost ≥ 20%, and a quarter lost ≥ 30% of their weight, at 48 weeks.

With the two highest doses of retatrutide, 100% of participants lost ≥ 5% of weight, Dr. Jastreboff reported, adding, “I’m not sure how many other times I will ever be able to say ‘100%’ in any scientific presentation.”

TRIUMPH phase 3 studies of retatrutide are ongoing.

“All the agents I’ve spoken about thus far are once-weekly injectable,” Dr. Jastreboff said, turning her attention to oral drugs.

Oral semaglutide (Rybelsus) is already FDA-approved for type 2 diabetes. The phase 2 OASIS trial results presented at ADA showed that participants with obesity who received 50 mg daily of the oral medication had an average weight reduction of 17.4% at 68 weeks, which is comparable to the 16.9% weight reduction with subcutaneous semaglutide 2.4 once weekly. More than a third of patients receiving the treatment lost ≥ 20% weight at 68 weeks.

The phase 3 OASIS study of oral semaglutide in obesity is ongoing.

Orforglipron. Phase 2 data of the small molecule oral GLP-1 RA orforglipron presented at ADA showed that participants with obesity had up to a 14.7% body weight reduction at 36 weeks. Nearly half of participants lost ≥ 15% of their body weight at 36 weeks.

The phase 3 ATTAIN study of orforglipron in obesity is ongoing.

AMG133. In a phase 2 trial, participants with obesity who received the monthly GIP receptor antagonist/ GLP-1 receptor agonist AMG133 (Amgen) had an average weight reduction of 14.5% at just 12 weeks.
 

Activin receptor inhibitors

Bimagrumab. This drug is a monoclonal antibody activin receptor inhibitor that binds to activin type II receptors. In a phase 2 study of 58 individuals with type 2 diabetes and obesity who received monthly medication or placebo, participants receiving bimagrumab lost 20.5% of fat mass and gained 3.6% of lean mass at 48 weeks, and the most common adverse events were mild diarrhea and muscle spasm.

Bimagrumab and semaglutide for obesity are being studied in BELIEVE, an ongoing phase 2b study. Topline results are anticipated by the end of 2024.

Taldefgrobep. The fusion protein taldefgrobep binds active myostatin. A phase 2 study of taldefgrobep for obesity is planned to start in 2024.

With nutrient-stimulated hormone therapies for obesity in phase 3 trials, and activin-receptor inhibitors the next upcoming drug class, highly effective treatments for obesity are on the horizon.

“We are at a watershed [moment] brought on by the recent introduction of highly effective antiobesity medications,” Ania M. Jastreboff, MD, PhD, said in a lecture at the annual meeting of the Obesity Society.

Dr. Jastreboff, of Yale University and the Yale Center for Weight Management, New Haven, Conn., provided an overview of the many nutrient-stimulated hormone-based antiobesity therapies in late phases of development – including dual and triple therapies with glucagon-like peptide 1 receptor agonists (GLP-1 RAs), glucose-dependent insulinotropic polypeptide (GIP) agonists, glucagon, and amylin.

“I’ve shown you all of these agents that clearly produce substantial weight reduction,” she said. “The fact that these nutrient-stimulated, hormone-based therapies are not all the same is a good thing,” she stressed, because “it’s not likely that everyone will respond to each of these, and they are likely to respond differently.”

She then briefly touched on activin receptor inhibitors –”the next [medication] class that I think will be up and coming,” she speculated.

“Beyond (just) weight reduction,” Dr. Jastreboff concluded, clinicians “need to focus on optimizing health as we are treating obesity.” Clinicians need to consider the patient’s severity of obesity, overall health, and metabolic profile, and match the obesity treatment to the patient. They also need to consider the rate of weight reduction, potential bone loss, vitamin deficiencies, muscle loss and function, and side effects, and be mindful of affordability, bias, and stigma.
 

Looking forward to multiple options

W. Timothy Garvey, MD, of the University of Alabama at Birmingham, told this news organization that clinicians treating patients with obesity are looking forward to the decision from the Food and Drug Administration about tirzepatide (Mounjaro), expected by year’s end. Tirzepatide “is really the best medicine that we have for diabetes in terms of A1c control without much hypoglycemia,” he said, “and also the best medicine for treating obesity in patients with diabetes.”

A recent study found that people with type 2 diabetes who adhered to their tirzepatide regimen achieved a 15% weight loss from their baseline after 40-42 weeks.

Dr. Garvey added that he is looking forward to drugs in development such as survodutide (a GLP-1/glucagon agonist) and orforglipron (a small oral daily nonpeptide GLP-1 RA). “Orforglipron wouldn’t have to be refrigerated,” he noted, and it “could be cheaper to manufacture, might be preferred over subcutaneous medication by some people, and it showed pretty good efficacy in early studies.”

Retatrutide, a triple agonist (GLP-1/GIP/glucagon) and CagriSema (cagrilintide plus semaglutide) showed “pretty impressive weight loss in early studies,” Dr. Garvey said. “We’re optimistic.”

Also invited to comment, Sean Wharton, MD, PharmD, Wharton Medical Clinic and York University, Toronto, said that the recent developments in antiobesity medications are “so exciting that it’s difficult to make direct comments,” since “maybe there will be something bigger, or maybe something will go wrong with these molecules and we’ll have to back-step.”

Further studies are needed, he added, to determine outcomes in patients who reduce their intake to half or three-quarters of a dose, or who transition to intermittent therapy.
 

Nutrient-stimulated, hormone-based antiobesity medications

Here’s a status overview of the nutrient-stimulated hormone-based medications already approved and on the horizon:

Semaglutide. The GLP-1 RA semaglutide (Ozempic), was approved by the FDA for type 2 diabetes in 2017. In June 2021, the FDA approved the use of semaglutide (Wegovy) for obesity.

Topline results from the Semaglutide Effects on Heart Disease and Stroke in Patients with Overweight or Obesity (SELECT) cardiovascular outcome trial showed that in individuals with obesity without type 2 diabetes, semaglutide led to a 20% reduction in major cardiovascular events, Dr. Jastreboff noted, adding that full results will be presented at the American Heart Association meeting on Nov. 11.

Tirzepatide. In May 2022, the FDA approved tirzepatide (Mounjaro), a GIP/GLP-1RA, for type 2 diabetes, and a decision about the use of tirzepatide for obesity is expected by year’s end.

The full results of the phase 3 SURMOUNT-3 trial were presented at ObesityWeek (just after this session), as reported by this news organization.

And the full results of the phase 3 SURMOUNT-4 trial of tirzepatide for obesity were presented at the European Association for the Study of Diabetes meeting, Dr. Jastreboff noted. At 88 weeks, in the continued tirzepatide group, average weight reduction was 26%, absolute weight reduction was 62 pounds (28.1 kg), and > 50% of individuals achieved ≥ 25% weight loss.

The phase 3 SURMOUNT MMO trial of morbidity and mortality with tirzepatide in obesity is estimated to be completed in 2027.

Cagrilintide. In a phase 2 trial of the amylin analog cagrilintide in patients with obesity, more than half of participants lost at least 10% of their weight at 26 weeks.

CagriSema. In a phase 1b trial of the amylin analog/GLP-1 RA combination of cagrilintide/semaglutide (CagriSema), average weight reduction at 20 weeks was 17.1%. The estimated primary completion dates of phase 3 trials of CagriSema, REDEFINE 1 (obesity), REDEFINE 2  (obesity and type 2 diabetes), and REDEFINE 3 (obesity and established cardiovascular disease), are 2025, 2024, and 2027, respectively. 

Survodutide. Findings from a phase 2 trial of the glucagon/GLP-1 RA survodutide were presented at the American Diabetes Association (ADA) meeting in June. With 46 weeks of treatment, the average weight reduction was 18.7%, and up to 40% of participants lost at least 20% of their body weight.

Survodutide is being studied in the phase 3 SYNCHRONIZE trials.

Retatrutide. Phase 2 findings of 12-mg weekly of the GIP/GLP-1/glucagon triple hormone receptor agonist retatrutide were also presented at ADA. On average, at 48 weeks, the placebo group lost 2.1% of their weight and the retatrutide group lost 24.2% of their weight, with an average absolute reduction of 58 pounds (26.3 kg). At the highest dose (12 mg), 9 out of 10 individuals lost ≥ 10%, nearly two-thirds lost ≥ 20%, and a quarter lost ≥ 30% of their weight, at 48 weeks.

With the two highest doses of retatrutide, 100% of participants lost ≥ 5% of weight, Dr. Jastreboff reported, adding, “I’m not sure how many other times I will ever be able to say ‘100%’ in any scientific presentation.”

TRIUMPH phase 3 studies of retatrutide are ongoing.

“All the agents I’ve spoken about thus far are once-weekly injectable,” Dr. Jastreboff said, turning her attention to oral drugs.

Oral semaglutide (Rybelsus) is already FDA-approved for type 2 diabetes. The phase 2 OASIS trial results presented at ADA showed that participants with obesity who received 50 mg daily of the oral medication had an average weight reduction of 17.4% at 68 weeks, which is comparable to the 16.9% weight reduction with subcutaneous semaglutide 2.4 once weekly. More than a third of patients receiving the treatment lost ≥ 20% weight at 68 weeks.

The phase 3 OASIS study of oral semaglutide in obesity is ongoing.

Orforglipron. Phase 2 data of the small molecule oral GLP-1 RA orforglipron presented at ADA showed that participants with obesity had up to a 14.7% body weight reduction at 36 weeks. Nearly half of participants lost ≥ 15% of their body weight at 36 weeks.

The phase 3 ATTAIN study of orforglipron in obesity is ongoing.

TOPLINE:

Higher triglyceride levels – a main energy source for the brain – are associated with lower risk for dementia that is not mediated by age, sex, or APOE epsilon-4 allele status, a large study of community-dwelling older adults suggests.

METHODOLOGY:

• The analysis included 18,294 participants, median age 75 years and median triglyceride level 106 mg/dL, from the Aspirin in Reducing Events in the Elderly (ASPREE) study, a placebo-controlled, randomized trial of daily low-dose aspirin in older people without dementia or history of cardiovascular disease (CVD) at recruitment.
• Researchers repeated their main analyses in a sub-cohort of 13,976 subjects with APOE epsilon-4 genetic data, and an external cohort of 68,200 participants, mean age 66.9 years and a median nonfasting triglyceride of 139 mg/dL, from the UK biobank, followed for a median of 12.5 years.
• The main outcome was incident dementia over 6.4 years and secondary outcomes included changes in composite cognitive function and domain-specific cognition.
• Researchers controlled for a number of potential confounders, including age, sex, race, smoking, alcohol consumption, education, family history of dementia, diabetes, hypertension, and statin use.

TAKEAWAY:

• Every doubling of baseline triglycerides was associated with an 18% lower risk of incident dementia across the entire study cohort (adjusted hazard ratio, 0.82) and in participants with genotypic data (aHR, 0.82) and a 17% lower risk in the external UK Biobank cohort (aHR, 0.83) (P ≤ .01 for all).
• In the entire cohort, the risk for dementia was 15% lower in those with triglyceride levels at 63-106 mg/dL (aHR, 0.85); 24% lower in those at 107-186 mg/dL (aHR, 0.76); and 36% lower for those with levels higher than 187 mg/dL (aHR, 0.64), compared with individuals with levels below 62 mg/dL (P for trend <.001).
• The direction and magnitude of the inverse association between triglycerides and dementia risk were not modified by age, sex, or risk factors related to triglycerides or dementia.
• In the entire study cohort, higher triglyceride levels were significantly associated with slower decline in global cognition (P = .02), composite cognition (P = .03), and a borderline significantly slower decline in episodic memory (P = .05).

IN PRACTICE:

“Triglyceride levels may serve as a useful predictor for dementia risk and cognitive decline in older populations,” the investigators write. Higher triglyceride levels may reflect better overall health and/or lifestyle behaviors that protect against dementia.

SOURCE:

The study was led by Zhen Zhou, of Monash University, Melbourne. It was published online in Neurology.

LIMITATIONS:

The study can’t establish a causal relationship between triglyceride levels and dementia or fully exclude reverse causality. As most ASPREE participants had normal to high-normal triglyceride levels, the results can’t be generalized to those with severe hypertriglyceridemia. The findings are unique to older people without CVD and may not be generalizable to other populations.

DISCLOSURES:

The study received support from the Royal Australian College of General Practitioners (RACGP)/HCF Research Foundation. Dr. Zhou reported receiving salary from the RACGP/HCF Research Foundation.

Studies have shown links between statin use and type 2 diabetes (T2D) for more than a decade. A U.S. Food and Drug Administration label change for the drugs warned in 2012 about reports of increased risks of high blood glucose and glycosylated hemoglobin (A1c) levels. However, in the same warning, the FDA said it “continues to believe that the cardiovascular benefits of statins outweigh these small increased risks.”

Indeed, although the warning triggered much discussion at the time and a number of meta-analyses and other observational studies in more recent years, that conclusion seems to hold among clinicians and society guidelines.

For example, in a recent practice pointer on the risk of diabetes with statins published in the BMJ, Ishak Mansi, MD, of the Orlando VA Health Care System, and colleagues write, “This potential adverse effect of diabetes with statin use should not be a barrier to starting statin treatment when indicated.”

They also called for further research to answer such questions as, “Is statin-associated diabetes reversible upon statin discontinuation? Would intermittent use minimize this risk while maintaining cardiovascular benefits?”

An earlier study among individuals at high risk for diabetes found significantly higher rates of incident diabetes at 10 years among patients on placebo, metformin, or lifestyle intervention who also initiated statin therapy. Jill Crandall, MD, Albert Einstein College of Medicine, New York, and colleagues conclude, “For individual patients, a potential modest increase in diabetes risk clearly needs to be balanced against the consistent and highly significant reductions in myocardial infarction, stroke, and cardiovascular death associated with statin treatment.”

In the same vein, a recent review by Byron Hoogwerf, MD, Emeritus, department of endocrinology, diabetes, and metabolism, Cleveland Clinic, is titled, “Statins may increase diabetes, but benefit still outweighs risk.”
 

Rosuvastatin versus Atorvastatin

The latest study in this arena is an analysis of the LODESTAR randomized controlled trial of 4,400 patients with coronary artery disease in 12 hospitals in Korea which compares the risks associated with individual statins.

Senior author Myeong-Ki Hong, MD, PhD, Yonsei University College of Medicine, Severance Cardiovascular Hospital, Seoul, South Korea, said in an interview that the study was prompted by the “limited” studies evaluating clinical outcomes, including diabetes risk, according to statin type.

Dr. Hong and colleagues compared the risk of developing diabetes among those taking rosuvastatin (mean daily dose, 17.1 mg) or atorvastatin (mean daily dose 36 mg) for 3 years. While both statins effectively prevented myocardial infarction, stroke, and death, those taking rosuvastatin had a higher incidence of new-onset T2D requiring initiation of antidiabetic drugs (7.2% vs. 5.3%; hazard ratio, 1.39) and cataract surgery (2.5% vs. 1.5%; HR, 1.66).

Overall, the HR of new-onset T2D was 1.29 (95% confidence interval, 1.01-1.63; P = .04).

“The percentages of new-onset diabetes and cataract are in line with previous studies regarding statin therapy in patients with atherosclerotic cardiovascular disease,” Dr. Hong said. “Additional research specifically focusing on these outcomes is required, with more frequent measurement of glucose and A1c levels to detect new-onset diabetes and regular ophthalmologic examinations to detect cataracts.”

“However,” he added, “when using rosuvastatin over atorvastatin, we ... emphasize the importance of meticulous monitoring and appropriate lifestyle interventions to mitigate the risk of new-onset diabetes or cataracts.”

Steven Nissen, MD, chief academic officer of Cleveland Clinic’s Heart and Vascular Institute, was not convinced, and said the study “does not provide useful insights into the use of these drugs.”

The investigators used whatever dose they wanted, “and the authors report only the median dose after 3 years,” he said in an interview. “Because there was a slightly greater reduction in low-density lipoprotein (LDL) cholesterol with rosuvastatin, the relative dose was actually higher.”

“We know that new-onset diabetes with statins is dose-dependent,” he said. “The P-values for diabetes incidence were marginal (very close to P = .05). Accordingly, the diabetes data are unconvincing. ... The similar efficacy is not surprising given the open-label dosing with relatively similar effects on lipids.”

Seth Shay Martin, MD, MHS, director of the Advanced Lipid Disorders Program and Digital Health Lab, Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins Medicine, Baltimore, also commented on the results. The findings are “in line with existing knowledge and current guidelines,” he said. “Therefore, the study should not influence prescribing.”

“Although the study suggests that rosuvastatin was associated with a higher risk of new-onset diabetes mellitus requiring antidiabetics and cataract surgery, compared with atorvastatin, these findings should be interpreted with caution given the open-label nature of the study and require further investigation,” he said.

“The mean daily doses of statins were somewhat below target for secondary prevention,” he noted. “Ideally, patients with coronary artery disease (CAD) take 20-40 mg daily of rosuvastatin or 40-80 mg daily of atorvastatin.”

“Furthermore, the LDL cholesterol levels were not optimized in the patients,” he said. “The mean LDL-C was 1.8-1.9 mmol/L, which is equivalent to 70-73 mg/dL. In the current treatment era, we generally treat to LDL-C levels less than 70 mg/dL and often less than 55 mg/dL in CAD patients.”

“The cataracts finding is particularly odd,” he added. “There was historic concern for cataracts with statin therapy, initially because of studies in beagle dogs. However, high-quality evidence from statin trials has not shown a risk for cataracts.” 

So which statin has the lowest risk of triggering new-onset diabetes? As Dr. Hong noted, the literature is sparse when it comes to comparing the risk among specific statins. Some studies suggest that the risk may depend on the individual and their specific risk factors, as well as the dose and intensity of the prescribed statin.

One recent study suggests that while the overall chance of developing diabetes is small, when looking at risk by years of exposure, atorvastatin, rosuvastatin, and lovastatin carried the largest risk, whereas the risk was lower with pravastatin and simvastatin.

Risks also seemed lower with fluvastatin and pitavastatin, but there were too few study patients taking those drugs long-term to include in the subanalysis.

With input from the latest guidelines from the American Heart Association and the American Diabetes Association, as well as findings from a clinical guide on statin-associated diabetes, Dr. Hoogwerf suggests in his review that shared decision-making before starting statin therapy of any type include the following considerations/discussion points:

• For all patients: Screening to determine baseline glycemic status; nonstatin therapies to lower cholesterol; and variables associated with an increased risk of diabetes, including antihypertensive drugs.
• For patients without T2D: The possibility of developing T2D, types and doses of statins, and the fact that statin benefits “generally far outweigh” risks of developing diabetes.
• For patients with T2D: Possible small adverse effects on glycemic control; statin benefits in reducing risk for atherosclerotic cardiovascular disease, which “significantly outweigh” the small increase in A1c; and mitigation of adverse glycemic effects of statins with glucose-lowering therapies.

It’s worth noting that the AHA and ADA guidelines, among others, also emphasize that such discussions should include the importance of weight loss, regular exercise, and adhering to a healthy lifestyle to mitigate risks of both diabetes and heart disease, with or without statins.

Dr. Hong, Dr. Nissen, and Dr. Martin report no relevant financial relationships. Dr. Hoogwerf has disclosed ownership interest in Eli Lilly and consulting for MannKind and Zealand Pharmaceuticals.

Studies have shown links between statin use and type 2 diabetes (T2D) for more than a decade. A U.S. Food and Drug Administration label change for the drugs warned in 2012 about reports of increased risks of high blood glucose and glycosylated hemoglobin (A1c) levels. However, in the same warning, the FDA said it “continues to believe that the cardiovascular benefits of statins outweigh these small increased risks.”

Indeed, although the warning triggered much discussion at the time and a number of meta-analyses and other observational studies in more recent years, that conclusion seems to hold among clinicians and society guidelines.

For example, in a recent practice pointer on the risk of diabetes with statins published in the BMJ, Ishak Mansi, MD, of the Orlando VA Health Care System, and colleagues write, “This potential adverse effect of diabetes with statin use should not be a barrier to starting statin treatment when indicated.”

They also called for further research to answer such questions as, “Is statin-associated diabetes reversible upon statin discontinuation? Would intermittent use minimize this risk while maintaining cardiovascular benefits?”

An earlier study among individuals at high risk for diabetes found significantly higher rates of incident diabetes at 10 years among patients on placebo, metformin, or lifestyle intervention who also initiated statin therapy. Jill Crandall, MD, Albert Einstein College of Medicine, New York, and colleagues conclude, “For individual patients, a potential modest increase in diabetes risk clearly needs to be balanced against the consistent and highly significant reductions in myocardial infarction, stroke, and cardiovascular death associated with statin treatment.”

In the same vein, a recent review by Byron Hoogwerf, MD, Emeritus, department of endocrinology, diabetes, and metabolism, Cleveland Clinic, is titled, “Statins may increase diabetes, but benefit still outweighs risk.”
 

Rosuvastatin versus Atorvastatin

The latest study in this arena is an analysis of the LODESTAR randomized controlled trial of 4,400 patients with coronary artery disease in 12 hospitals in Korea which compares the risks associated with individual statins.

TOPLINE:

Time-restricted eating (TRE), also known as intermittent fasting, for a daily 8-hour period without calorie counting produced greater weight loss among people with type 2 diabetes and obesity, compared with calorie restriction, while hemoglobin A1c levels dropped with both approaches, compared with no intervention.

METHODOLOGY:

• Six-month clinical trial of 75 adult participants with type 2 diabetes and obesity, randomly assigned to either 8-hour TRE (noon to 8 p.m. only) without calorie counting, a 25% daily calorie restriction, or control.

TAKEAWAY:

• The primary outcome, change in body weight at month 6, was –3.56% (P = .004) with TRE vs. –1.78% with calorie restriction (P = .06), compared with controls.
• The mean calorie deficit over the 6 months was –313 kcal/day with TRE, –197 kcal/day with calorie restriction, and –16 kcal/day for controls.
• Self-reported adherence to the regimens was 87% of days with 8-hour TRE vs. 68% reporting adherence with calorie goals over the 6 months.  
• A1c levels were reduced significantly by 0.91% in the TRE group and 0.94% in the calorie-restriction group, relative to controls, with no differences between the two intervention groups.
• No serious adverse events were reported.
• Hypoglycemia and hyperglycemia occurrences didn’t differ between groups.

IN PRACTICE:

“Our findings ... show that TRE is safe in patients who are using either diet alone or medications to control their [type 2 diabetes]. However, for people using sulfonylureas and/or insulin, adopting a TRE regimen will require medication changes and regular monitoring, particularly in the initial stages of the diet.”

SOURCE:

The study was conducted by Vasiliki Pavlou, MS, RD, of the department of kinesiology and nutrition, University of Illinois at Chicago, and colleagues. It was published online in JAMA Network Open.

LIMITATIONS:

• Relatively short trial duration.
• Lack of blinding.
• A higher proportion in the TRE group were using newer type 2 diabetes medications at baseline.
• Self-reported dietary intake.

DISCLOSURES:

The study was supported by the University of Illinois at Chicago, and by grants from the National Institutes of Health. Ms. Pavlou reports no relevant financial relationships. Several authors reported relationships with industry. The full list can be found with the original article.

Your patients may see ads claiming that testosterone replacement therapy (TRT) offers postmenopausal women health benefits beyond restored sex drive: that TRT can improve their mood, energy, and thinking and give them stronger bones and bigger muscles.

How accurate are these claims? According to six experts who talked with this news organization, not very.

“Right now in this country and around the world, testosterone’s only use in postmenopausal women is for libido,” said Adrian Sandra Dobs, MD, MHS, professor of medicine and director of the Johns Hopkins Clinical Research Network at Johns Hopkins Medicine, Baltimore.

“Treating postmenopausal women with testosterone is a rarity. Some physicians and some wellness centers make their money out of prescribing estrogen and testosterone to women in patches, gels, creams, capsules, pellets, and other forms. But when you look at the scientific data, outside of libido, it’s difficult to recommend testosterone therapy,” she added by phone.

“One has to be very careful about using testosterone in women,” Dr. Dobs cautioned. “There’s a lot of hype out there.”

Low testosterone in women has not been well studied, and no testosterone treatments for this condition have been approved by the U.S. Food and Drug Administration. Providers need to adjust male treatment data to their female patients, who require significantly lower doses than males. Contraindications and long-term side effects are poorly understood, said Mary Rosser, MD, PhD, assistant professor of women’s health and director of integrated women’s health at Columbia University Irving Medical Center, New York.

“Despite this preponderance of scientific evidence and recommendations, the myths about testosterone die hard, including that it improves women’s muscle function, endurance, and well-being,” Dr. Rosser said.

“Websites that use compounded products or pellets are not FDA-regulated; therefore, they have no responsibility to prove their claims. They can entice women into using this stuff with all kinds of promises about ‘hormone balancing’ and other meaningless terms. The Endocrine Society statement reviewed the clinical studies on testosterone for various indications surrounding physical endurance, well-being, and mental health – and the studies do not support its use,” Dr. Rosser added.

According to the Australasian Menopause Society, women’s blood testosterone levels tend to peak in their 20s, slowly decline to around 25% of peak levels at menopause, then rise again in later years.

Susan Davis, PhD, and her colleagues at Monash University, Melbourne, found in a study that TRT in postmenopausal women may improve sexual well-being and that side effects include acne and increased hair growth. But they found no benefits for cognition, bone mineral density, body composition, muscle strength, or psychological well-being, and they note that more data are needed on long-term safety.
 

Postmenopausal testosterone recommended for libido only

“Hypoactive sexual desire disorder (HSDD) is really the only indication for postmenopausal testosterone use,” Nanette F. Santoro, MD, professor and chair of obstetrics and gynecology at the University of Colorado School of Medicine, Aurora, noted by email. “In clinical studies using androgen gel containing testosterone, testosterone treatment has resulted in a mean of one more satisfying sexual encounter per month. Consensus statements issued by the Endocrine Society, The International Menopause Society, and the North American Menopause Society have come to similar conclusions: The only indication for androgen therapy for women is HSDD,” added Santoro, an author of the Endocrine Society statement.

“Sexual health and the sense of well-being are very much related,” Sandra Ann Carson, MD, professor of obstetrics and gynecology at Yale Medicine, New Haven, Conn., said by phone. “So we give testosterone to increase sexual desire. Testosterone is not a treatment for decreased sense of well-being alone. Women who lose their sense of well-being due to depression or other factors need to have a mental health evaluation, not testosterone.”

“Because no female product is presently approved by a national regulatory body, male formulations can be judiciously used in female doses and blood testosterone concentrations must be monitored regularly,” Dr. Rosser said. “The recommendation is for considering use of compounded testosterone for hypoactive sexual desire only; it is against use for overall health and wellness.”

“The real mischief occurs when women are exposed to doses that are supraphysiologic,” Dr. Rosser cautioned. “At high doses that approach and sometimes exceed men’s levels of testosterone, women can have deepening of the voice, adverse changes in cholesterol, and even breast atrophy. This can occur with bioidentical compounded testosterone and with testosterone pellets. The National Academies of Science, Engineering, and Medicine recommend unequivocally that such preparations not be used.”

Not all postmenopausal women should take TRT, said Meredith McClure, MD, assistant professor in the department of obstetrics and gynecology of UT Southwestern Medical School, Dallas, because it has only been shown in trials to help with HSDD.

She advised clinicians to avoid prescribing testosterone to patients who “can’t take estrogen, including if [they] have hormone-sensitive cancer, blood clot risk, liver disease, heart attack, stroke, or undiagnosed genital bleeding.”
 

TRT for non-libido issues may sometimes be appropriate

“Perhaps women with hip fracture or cancer cachexia could benefit from testosterone to build muscle mass,” said Dr. Dobbs, who is involved in an ongoing study of testosterone treatment in women with hip fracture. “But as yet, we have no proof that testosterone helps.”

In rare cases, Stanley G. Korenman, MD, a reproductive endocrinologist and associate dean for ethics at UCLA Health, treats postmenopausal patients with TRT for reasons other than low libido. “I have a very specialized practice in reproductive endocrinology and internal medicine and am one of very few people in the country who do this kind of management,” he said in an interview. “If my postmenopausal patients have low testosterone and lack energy, I’m willing to give them low doses. If they feel more energetic, we continue, but if they don’t, we stop. I don’t think there’s any risk whatsoever at the low level I prescribe.

“I prescribe standard gel that comes in a squirt bottle, and I suggest they take half a squirt every other day – about one-eighth of a male dose – on the sole of the foot, where hair does not grow.

“I would not prescribe testosterone for bone health. We have bisphosphonates and other much better treatments for that. And I would not prescribe it to someone who is seriously emotionally disturbed or seriously depressed. This is not a treatment for depression.”

“Postmenopausal testosterone is not ‘the latest greatest thing,’ but being very low risk, it’s worth trying once in a while, in the appropriate patient, at the right dose,” Dr. Korenman advised. He cautioned people to “avoid the longevity salespeople who sell all sorts of things in all sorts of doses to try to keep us alive forever.”

Your patients may see ads claiming that testosterone replacement therapy (TRT) offers postmenopausal women health benefits beyond restored sex drive: that TRT can improve their mood, energy, and thinking and give them stronger bones and bigger muscles.

How accurate are these claims? According to six experts who talked with this news organization, not very.

“Right now in this country and around the world, testosterone’s only use in postmenopausal women is for libido,” said Adrian Sandra Dobs, MD, MHS, professor of medicine and director of the Johns Hopkins Clinical Research Network at Johns Hopkins Medicine, Baltimore.

“Treating postmenopausal women with testosterone is a rarity. Some physicians and some wellness centers make their money out of prescribing estrogen and testosterone to women in patches, gels, creams, capsules, pellets, and other forms. But when you look at the scientific data, outside of libido, it’s difficult to recommend testosterone therapy,” she added by phone.

“One has to be very careful about using testosterone in women,” Dr. Dobs cautioned. “There’s a lot of hype out there.”

Low testosterone in women has not been well studied, and no testosterone treatments for this condition have been approved by the U.S. Food and Drug Administration. Providers need to adjust male treatment data to their female patients, who require significantly lower doses than males. Contraindications and long-term side effects are poorly understood, said Mary Rosser, MD, PhD, assistant professor of women’s health and director of integrated women’s health at Columbia University Irving Medical Center, New York.

“Despite this preponderance of scientific evidence and recommendations, the myths about testosterone die hard, including that it improves women’s muscle function, endurance, and well-being,” Dr. Rosser said.

“Websites that use compounded products or pellets are not FDA-regulated; therefore, they have no responsibility to prove their claims. They can entice women into using this stuff with all kinds of promises about ‘hormone balancing’ and other meaningless terms. The Endocrine Society statement reviewed the clinical studies on testosterone for various indications surrounding physical endurance, well-being, and mental health – and the studies do not support its use,” Dr. Rosser added.

According to the Australasian Menopause Society, women’s blood testosterone levels tend to peak in their 20s, slowly decline to around 25% of peak levels at menopause, then rise again in later years.

Susan Davis, PhD, and her colleagues at Monash University, Melbourne, found in a study that TRT in postmenopausal women may improve sexual well-being and that side effects include acne and increased hair growth. But they found no benefits for cognition, bone mineral density, body composition, muscle strength, or psychological well-being, and they note that more data are needed on long-term safety.
 

Postmenopausal testosterone recommended for libido only

“Hypoactive sexual desire disorder (HSDD) is really the only indication for postmenopausal testosterone use,” Nanette F. Santoro, MD, professor and chair of obstetrics and gynecology at the University of Colorado School of Medicine, Aurora, noted by email. “In clinical studies using androgen gel containing testosterone, testosterone treatment has resulted in a mean of one more satisfying sexual encounter per month. Consensus statements issued by the Endocrine Society, The International Menopause Society, and the North American Menopause Society have come to similar conclusions: The only indication for androgen therapy for women is HSDD,” added Santoro, an author of the Endocrine Society statement.

“Sexual health and the sense of well-being are very much related,” Sandra Ann Carson, MD, professor of obstetrics and gynecology at Yale Medicine, New Haven, Conn., said by phone. “So we give testosterone to increase sexual desire. Testosterone is not a treatment for decreased sense of well-being alone. Women who lose their sense of well-being due to depression or other factors need to have a mental health evaluation, not testosterone.”

“Because no female product is presently approved by a national regulatory body, male formulations can be judiciously used in female doses and blood testosterone concentrations must be monitored regularly,” Dr. Rosser said. “The recommendation is for considering use of compounded testosterone for hypoactive sexual desire only; it is against use for overall health and wellness.”

“The real mischief occurs when women are exposed to doses that are supraphysiologic,” Dr. Rosser cautioned. “At high doses that approach and sometimes exceed men’s levels of testosterone, women can have deepening of the voice, adverse changes in cholesterol, and even breast atrophy. This can occur with bioidentical compounded testosterone and with testosterone pellets. The National Academies of Science, Engineering, and Medicine recommend unequivocally that such preparations not be used.”

Not all postmenopausal women should take TRT, said Meredith McClure, MD, assistant professor in the department of obstetrics and gynecology of UT Southwestern Medical School, Dallas, because it has only been shown in trials to help with HSDD.

She advised clinicians to avoid prescribing testosterone to patients who “can’t take estrogen, including if [they] have hormone-sensitive cancer, blood clot risk, liver disease, heart attack, stroke, or undiagnosed genital bleeding.”
 

TRT for non-libido issues may sometimes be appropriate

“Perhaps women with hip fracture or cancer cachexia could benefit from testosterone to build muscle mass,” said Dr. Dobbs, who is involved in an ongoing study of testosterone treatment in women with hip fracture. “But as yet, we have no proof that testosterone helps.”

Polycystic ovary syndrome (PCOS) is associated with an increased risk of gestational diabetes, but this risk is heightened significantly in the presence of obesity, according to new research.

In a population-based cohort study that included more than 1.2 million hospital live births, PCOS was associated with a 5% increase in risk for gestational diabetes. Almost 90% of this association was mediated by obesity.

“Women with PCOS are at higher risk, but it’s only 5% higher than the general population. However, that risk rises substantially with obesity,” senior author Maria P. Velez, MD, PhD, clinician-scientist and associate professor of obstetrics and gynecology at Queen’s University, Kingston, Ont., said in an interview. “Our study highlights the need for counseling our patients about the importance of weight optimization, ideally starting with lifestyle changes like diet and exercise.”The findings were published  in the Journal of Obstetrics and Gynaecology Canada.
 

Major mediator

The estimated prevalence of PCOS is 8%-13%, and affected patients often present with anovulation, hyperandrogenism, obesity, metabolic syndrome, and infertility. Prepregnancy insulin resistance is common among women with PCOS and may play a major part in the pathogenesis of gestational diabetes. In addition, PCOS is often accompanied by excess weight gain; about 60% of women with PCOS are overweight or obese.

Previous research has shown that PCOS is a risk factor for gestational diabetes independent of obesity, while other research has shown that obesity has an important effect on this risk.

For the current study, the researchers used causal mediation analysis to elucidate more clearly the effect of obesity on the development of gestational diabetes among patients with PCOS. No previous study has used causal mediation analysis to examine this relationship.

Using data from linked universal health databases in Ontario, the researchers analyzed data on 1,268,901 births between 2006 and 2018. Of these births, 386,748 were associated with maternal PCOS.

The rate of gestational diabetes was higher among women with PCOS (60.2 per 1000 births), compared with women without PCOS (48.6 per 1,000 births). The finding resulted in an adjusted relative risk of 1.05. Obesity mediated 89.7% of this association.

“We hope that these data will inform preconception counseling and gestational diabetes screening in pregnant women with PCOS,” said Dr. Velez. “We have the data now to counsel our patients on the importance of weight management before pregnancy. But we need more resources, such as specialized clinics, to help these patients cope with managing their weight. We can tell our patients to work on their weight management, but they need much more support from the health care system.”
 

Results ‘not surprising’

Commenting on the study, Francine Hippolyte, MD, vice chair of obstetrics and gynecology at Long Island Jewish Medical Center, Katz Women’s Hospital, New Hyde Park, N.Y., said that the results are “not at all surprising.” Dr. Hippolyte was not involved in the research.

“We do know that PCOS is and should be treated as a metabolic syndrome. It’s a lot more than just infertility or changes or abnormalities with one’s menstrual cycle. It impacts a woman’s risk for diabetes, prediabetes, and abnormal lipid profile, regardless of whether or not she is obese,” said Dr. Hippolyte.

She agrees with the need for specialized clinics to help such vulnerable patients manage their weight.

“It would be great if insurances would cover things like nutritional counseling or have nutritionists on their roster so that patients can easily access that service. Many patients want to do right, especially preconceptually, but it is difficult without having access to resources. Unfortunately, as clinicians, we’re not as well versed in nutrition as we would like to be or should be, so we need a multidisciplinary approach. We need nutrition and weight loss clinics and proper services to really help these patients.”

The study was supported by the Canadian Institute of Health Research and ICES. Dr. Velez and Dr. Hippolyte reported no relevant financial relationships.

Commercial sperm banks in the United States lack racially and ethnically diverse donors, potentially limiting family-planning options for patients in traditionally underserved populations, according to a study presented at the American Society for Reproductive Medicine’s 2023 meeting.

“This really highlights the need to identify barriers to increase recruitment of these donors so that we can support family-building for all populations,” said Lauren Gibbs, MD, a resident in the department of obstetrics and gynecology at the Morehouse School of Medicine in Atlanta.

Dr. Gibbs and her colleagues compared the racial and ethnic makeup of sperm donors from online and self-reported profiles at 14 of the largest donor banks in the United States for March and April of 2023. Historical data were pulled from two large, national banks. The investigators compared these data to census estimates from 2021 for men between the ages of 18 and 44 years.

Donors who identified as Hispanic (10.9%) or Black (3.3%) were significantly underrepresented as compared to the U.S. population, of which Hispanic men compose 22% and Black men make up 13.3%.

Asian donors were overrepresented, making up 21.9% of the donors but only 6.5% of the U.S. population. White donors were proportionately represented in relation to national demographics, making up 56.6% of the donors and representing 55% of the U.S. population, according to the researchers. None of the donors identified as Native/Hawaiian/Pacific Islander or American Indian/Alaskan Natives; these groups represent 0.22% and 0.79% of the U.S. population, respectively.

“Next steps will be figuring out why this is happening and how to address it,” said Valerie L Baker, MD, director in the division of reproductive endocrinology and infertility at Johns Hopkins Medicine in Lutherville, Md., who was not involved in the study.

The study sheds light on the need to identify and address the barriers that discourage potential donors from underrepresented groups from participating in sperm donation, according to Kimball Pomeroy, PhD, scientific director at the World Egg and Sperm Bank in Scottsdale, Ariz.

“Sometimes there are inhibitors of different ethnic groups to want to act as sperm or egg donors, so trying to understand if that’s the case is important; but I’m sure a lot of it is also related to access,” Dr. Pomeroy, who was not part of the study team, said in an interview.

Longitudinal data from the two national donor banks did not indicate any significant increase or decrease in donation trends across the 5-year period from 2018 to 2022, highlighting the persisting issue of representation disparities. Dr. Gibbs said strategies need to be developed to increase recruitment of donors from underrepresented groups. Increasing the diversity of the donor pool will ultimately support family-building options for all patients, according to Dr. Gibbs.

Funding for the study was provided by the EMD Serono REI Diversity Fellowship Grant. Dr. Gibbs reports no relevant financial relationships.

The study sheds light on the need to identify and address the barriers that discourage potential donors from underrepresented groups from participating in sperm donation, according to Kimball Pomeroy, PhD, scientific director at the World Egg and Sperm Bank in Scottsdale, Ariz.

“Sometimes there are inhibitors of different ethnic groups to want to act as sperm or egg donors, so trying to understand if that’s the case is important; but I’m sure a lot of it is also related to access,” Dr. Pomeroy, who was not part of the study team, said in an interview.

Longitudinal data from the two national donor banks did not indicate any significant increase or decrease in donation trends across the 5-year period from 2018 to 2022, highlighting the persisting issue of representation disparities. Dr. Gibbs said strategies need to be developed to increase recruitment of donors from underrepresented groups. Increasing the diversity of the donor pool will ultimately support family-building options for all patients, according to Dr. Gibbs.

Funding for the study was provided by the EMD Serono REI Diversity Fellowship Grant. Dr. Gibbs reports no relevant financial relationships.

VANCOUVER – Use of sodium glucose cotransporter-2 (SGLT2) inhibitors is associated with a reduced risk of gastrointestinal cancers among patients with type 2 diabetes, compared with dipeptidyl peptidase IV (DPP4) inhibitors, new evidence reveals.

The SGLT2 inhibitors emerged superior to DPP4 inhibitors for reducing risk of colorectal, hepatic, esophageal, and other GI cancers except pancreatic cancer, said study investigator Shu-Yen Emily Chan, MD, a gastroenterologist in the departments of medicine and epidemiology at Weiss Memorial Hospital, Chicago.

On the basis of the findings, physicians could consider the SGLT2s canagliflozin, dapagliflozin, and empagliflozin or a GLP-1 as first-line therapy, particularly for people with T2D who are at elevated risk for GI cancers, Dr. Chan said in an interview at the American College of Gastroenterology (ACG): 2023 Annual Scientific Meeting.

Previous research focused on potential cardiovascular or renal benefits associated with SGLT2s, “but there are few looking at GI cancer risk and these medications,” she added. Most earlier studies in cancer have been preclinical and observational studies on colorectal cancer or hepatocellular carcinoma.

Using the TriNetX database of millions of medical claims from 92 hospitals across the United States, Dr. Chan and colleagues identified 706,390 adults who began first-line SGLT2 inhibitor therapy. They used propensity matching to link these patients with 706,390 other adults who began taking a DDP4 inhibitor (sitagliptin, saxagliptin, linagliptin, or alogliptin).

All participants had been diagnosed with type 2 diabetes. Patients were prescribed an SGLT2 inhibitor at least three times, and any cancer diagnosis that occurred at least 6 months after starting therapy was noted. Anyone with a history of cancer, cancer recurrence, or metastatic disease was excluded from the population-based cohort study.

In addition to evaluating a large number of patients, the study is notable for including people with ulcerative colitis and Crohn’s disease and for evaluating every GI cancer – esophageal, gastric, small intestinal, colorectal, rectal, anal, hepatic, biliary, and gallbladder malignancies.
 

Key findings

Among adults who received an SGLT2 inhibitor, there was a 15% decrease in overall risk of developing any GI cancer, compared with those who received a DPP4 inhibitor (hazard ratio, 0.85; 95% confidence interval, 0.82-0.88).

Colon cancer was the most common malignancy in the study. Dr. Chan and colleagues identified colon cancer among 1,789 people, or 0.25% of those taking an SGLT2 inhibitor, compared with 3,283 people, or 0.46%, of those taking a DPP4 inhibitor.

SGLT2 inhibitors were associated with a 16% decrease in risk of gastric cancer (HR, 0.84; 95% CI; 0.74-0.945; P = .005), a 13% decrease in risk of liver and intrahepatic bile duct cancer (HR, 0.87; 95% CI, 0.81-0.95), and a 22% decrease in risk of colon cancer (HR, 0.781; 95% CI, 0.74-0.83; P < .001), compared with the DPP4 medications.

The only cancer more likely in the SGLT2 inhibitor group than in the DPP4 inhibitor group was pancreatic cancer (HR, 1.035; 95% CI, 0.964-1.111; P = .340).

The SLGT2 inhibitor class also was superior to metformin for reducing risk of GI cancers.

Asked whether the study findings should alter current practice, Dr. Chan said that the study is new and hasn’t yet been published. “More studies will be needed and included in official guidelines before the findings become practice-changing,” she said.

Limitations of the study include residual confounding, absence of family cancer history, and information bias. Strengths include the large, national database and propensity score matching.
 

‘Eye-opening’ study

“It is a good study, and eye-opening because it shows that one class of diabetes medications is better than another one,” said session co-moderator Kenneth J. Vega, MD, professor of medicine and chief of the division of gastroenterology and hepatology at Augusta University–Medical College of Georgia.

Dr. Vega shared his theory on why diabetes medications could reduce risk of GI cancers. “I would think reducing diabetes means you can control inflammation ... and better controlling inflammation leads you to have less cancers.”

He added, “I think we need more long-term studies.”

The study was independently supported. Dr. Chan and Dr. Vega report no relevant financial relationships.
