For the first time, the Food and Drug Administration approved a pill taken once daily for 14 days to help women manage the often strong, sometimes overpowering symptoms of postpartum depression.

Several experts in mental health and women’s health offered their views of this new treatment option for a condition that affects an estimated 1 in 8 women in the United States. What will it mean for easing symptoms such as hopelessness, crankiness, and lack of interest in bonding with the baby or, in the case of multiples, babies – and in some cases, thoughts of death or suicide?
 

A fast-acting option

“We don’t have many oral medications that are fast-acting antidepressants, so this is incredibly exciting,” said Sarah Oreck, MD, a psychiatrist in private practice in Los Angeles who specializes in reproductive psychiatry. The rapid response is likely because the medication targets the hormonal mechanism underlying postpartum depression, she added.

Zuranolone (Zurzuvae, Biogen/Sage) is different from most other antidepressants – it is designed to be taken for a shorter period. Also, Because zuranolone is a pill, it is more convenient to take than the other FDA-approved treatment, the IV infusion brexanolone (Zulresso, Sage).

“It’s obviously game changing to have something in pill form. The infusion has to be done at an infusion center to monitor people for any complications,” said Kimberly Yonkers, MD, a psychiatrist specializing in women’s health, a Distinguished Life Fellow of the American Psychiatric Association (APA), and the Katz Family Chair of Psychiatry at the University of Massachusetts Chan Medical School/UMass Memorial Medical Center in Worcester.

Women may experience improvement in postpartum depression in as soon as 3 days after starting the medication. In contrast, “typical antidepressants can take up to 2 weeks before patients notice a difference and 4 to 8 weeks to see a full response. A fast-acting pill that can be taken orally could be an ideal option for the 15% to 20% of women who experience postpartum depression,” said Priya Gopalan, MD, a psychiatrist with UPMC Western Psychiatric Hospital and Magee-Womens Hospital in Pittsburgh.

The medical community, and reproductive psychiatrists in particular, has always suspected differences in the biological underpinnings of postpartum depression and major depressive disorder, Dr. Oreck said. “We know that postpartum depression looks different from major depressive disorder and that hormonal shifts during pregnancy and postpartum are a huge risk factor for postpartum depression,” she said.

Although selective serotonin reuptake inhibitors (SSRIs) are helpful and currently the standard of care for treating moderate to severe postpartum depression in combination with therapy, Dr. Oreck added, early studies suggest that zuranolone may work faster and potentially be more effective than SSRIs in treating the condition.

Zuranolone is a version of a naturally occurring hormone called allopregnanolone, a metabolite of progesterone. Concentrations of allopregnanolone rise dramatically during pregnancy and then drop precipitously after childbirth. Zuranolone works through modulating GABA-A, a neurotransmitter implicated in the development of depression.

“It is encouraging that postpartum individuals may now have more options to manage a debilitating condition that affects them and their families,” said Christopher Zahn, MD, interim CEO and chief of clinical practice and health equity and quality for the American College of Obstetricians and Gynecologists (ACOG).

ACOG recommends women be screened for depression at least three times – during early pregnancy, later in pregnancy, and again after delivery. A decision to start this or any other medicine should be individualized and based on shared decision-making between a patient and doctor, Dr. Zahn added.

The cost of zuranolone is not yet known. Dr. Yonkers said cost of the infusion can serve as a cautionary tale for the manufacturer. Some reports put the infusion cost at $34,000. “Cost is going to be an important component to this. The previous intervention was priced so high that it was not affordable to many people and it was difficult to access.”
 

Beyond ‘baby blues’

The APA has changed the name from “postpartum depression” to “peripartum depression” because evidence suggests feelings and symptoms also can start late in pregnancy. “It means you don’t have to wait until somebody delivers to screen for depression. We have to recognize that depression can occur during pregnancy,” Dr. Yonkers said. “In fact it is not uncommon during the third trimester.”

No matter when it starts, the condition can be “very serious,” particularly if the person already experiences depression, including bipolar disorder, Dr. Yonkers added.

Postpartum depression “is more than just ‘baby blues.’ It is a potentially debilitating illness that causes feelings of intense sadness and worthlessness, making it difficult to care for and bond with your newborn,” Dr. Gopalan said.
 

Can be a medical emergency

Severe postpartum depression requires immediate attention and treatment.

“One of the things we have to be cautious about is for people with previous predisposition to hurt themselves,” Dr. Yonkers said. “It is therefore important to consider somebody’s medical and behavioral health history as well.

“For an individual with recurring depression or severe episodes of depression, this may not be sufficient, because they are just going to get these 14 days of therapy,” Dr. Yonkers said. “They may need ongoing antidepressants.

“It may not be the right pill for everybody,” Dr. Yonkers added. She recommended everyone be followed closely during and after treatment “to make sure they are responding and to monitor for relapse.”
 

The science that led to approval

The clinical trials showed early response in patients with severe postpartum depression. Researchers conducted two studies of women who developed a major depressive episode in the third trimester of pregnancy or within 4 weeks of delivery. They found women who took zuranolone once in the evening for 14 days “showed significantly more improvement in their symptoms compared to those in the placebo group.”

The antidepressant effect lasted at least 4 weeks after stopping the medication.

Drowsiness, dizziness, diarrhea, fatigue, nasopharyngitis, and urinary tract infection were the most common side effects. The label has a boxed warning noting that the medication can affect a person’s ability to drive and perform other potentially hazardous activities. Use of zuranolone may also cause suicidal thoughts and behavior, according to an FDA news release announcing the approval.
 

The start of more help for mothers?

Zuranolone is not a cure-all. As with most psychiatric prescriptions, the medication likely will work best in conjunction with behavioral health treatments such as psychotherapy, use of other medications, behavioral management, support groups, and self-care tools such as meditation, exercise, and yoga, Dr. Gopalan said.

Dr. Oreck said she hopes this first pill approval will lead to more discoveries. “I hope this is the beginning of more innovation and development of novel treatments that can target women’s mental health issues specifically – female reproductive hormones impact mental health in unique ways and it’s exciting to finally see research and development dollars dedicated to them,” she said. “The FDA approval of this pill provides the potential to improve the lives of millions of Americans suffering from postpartum depression.”

Dr. Oreck, Dr. Yonkers, Dr. Gopalan, and Dr. Zahn have disclosed no relevant financial relationships.

Drinking sugar-laden beverages on a regular basis may increase the risk for liver cancer and death from chronic liver disease, new research suggests.

The observational analyses revealed that postmenopausal women who consumed at least one sugar-sweetened beverage daily had an 85% higher risk of developing liver cancer and a 68% higher risk of dying from chronic liver disease, compared with those who consumed three servings or fewer per month.

“If our findings are confirmed, reducing sugar-sweetened beverage consumption might serve as a public health strategy to reduce liver disease burden,” first author Longgang Zhao, PhD, with Brigham and Women’s Hospital and Harvard Medical School, both in Boston, said in an interview.

When looking at consumption of artificially sweetened drinks, however, Dr. Zhao and colleagues found no strong association between intake and risk for liver cancer or death from chronic liver disease. Because the sample size for the artificially sweetened beverage analysis was limited, Dr. Zhao said, “these results should be interpreted with caution and additional studies are needed to confirm our study findings.”

The new study was published online in JAMA.

About 40% of people with liver cancer do not have one of the well-known disease risk factors, such as chronic hepatitis B or C infection, type 2 diabetes, or obesity. In the current analysis, Dr. Zhao and colleagues wanted to determine whether sugar-sweetened or artificially sweetened beverages, consumed by a large swath of the population, could be a risk factor for liver cancer or chronic liver disease.

Two previous studies have found only a “potential association” between sugar-sweetened beverage intake and a person’s risk for liver cancer, the authors explained.

In July, the International Agency for Research on Cancer officially classified the artificial sweetener aspartame as a possible carcinogen, but cancer epidemiologist Paul Pharoah, MD, PhD, commented that “the evidence that aspartame causes primary liver cancer, or any other cancer in humans, is very weak.”

To provide greater clarity about a potential link, the study team used the Women’s Health Initiative to evaluate sugary beverage consumption among 98,786 postmenopausal women and artificially sweetened drink intake among 64,787 followed for up to a median of 20.9 years. The primary outcomes were liver cancer incidence and mortality from chronic liver disease, defined as nonalcoholic fatty liver disease, liver fibrosis, cirrhosis, alcoholic liver diseases, and chronic hepatitis.

Among these women, nearly 7% consumed at least one sugar-sweetened beverage daily and 13% consumed one or more artificially sweetened beverage servings daily.

Over the follow-up period, 207 women developed liver cancer and 148 died from chronic liver disease in the sugary beverage group while 133 women developed liver cancer and 74 died from chronic liver disease in the artificial sugar group.

Compared with women consuming three servings or fewer of sugar-sweetened beverages per month, those consuming one or more servings per day had a significantly higher risk for liver cancer (18.0 vs. 10.3 per 100,000; adjusted hazard ratio, 1.85; P = .01) and for chronic liver disease mortality (17.7 vs. 7.1 per 100,000; aHR, 1.68; P = .04).

Compared with women consuming three servings or fewer of artificially sweetened beverages per month, those drinking one or more servings per day did not have a significantly increased risk for liver cancer (11.8 vs. 10.2 per 100,000; aHR, 1.17; P = .55) or chronic liver disease mortality (7.1 vs. 5.3 per 100,000; aHR 0.95; P = .88).

The authors noted several limitations to the study, including not tracking potential changes in beverage consumption over time or details on the specific sugar content or sweetener types consumed.

Corresponding author Xuehong Zhang, ScD, also with Brigham and Women’s Hospital and Harvard Medical School, said it’s not surprising that sugar-sweetened beverages may raise the risk of adverse liver outcomes.

“Intake of sugar-sweetened beverage[s], a postulated risk factor for obesity, diabetes, and cardiovascular disease, may drive insulin resistance and inflammation, which are strongly implicated in liver carcinogenesis and liver health,” Dr. Zhang said in an interview.

The lack of an association between artificially sweetened beverages and liver outcomes is also not particularly surprising, Dr. Zhang said, “given that the consumption level of artificially sweetened beverages is low, the sample size is relatively small,” and “the dose response relationship remains unknown.”

Nancy S. Reau, MD, who was not involved in the research, said the authors should be “congratulated for trying to clarify liver-related health risk related to artificial or sugar-sweetened beverages.”

In her view, the most important finding is the association between daily consumption of sugar-sweetened beverages and liver health.

“Regardless of whether this is a surrogate marker for liver disease risk (such as fatty liver disease) or a consequence of the drink itself, it is an easy measure for clinicians to capture and an easy behavior for patients to modify,” Dr. Reau, a hepatologist at Rush Medical College, Chicago, said in an interview.

However, Dr. Reau noted, “I do not feel that this article can be used to advocate for artificially sweetened beverages as a substitute.”

It is possible, she explained, that this population was too small to see a significant signal between artificially sweetened beverages and liver health. Plus, “natural, low-caloric beverages as part of a healthy diet combined with exercise are always going to be ideal.”

Weighing in as well, Dale Shepard, MD, PhD, a medical oncologist at the Cleveland Clinic, noted that “this is another study that points to the need for moderation.”

In his view, avoiding excess consumption of sugary or artificially sweetened drinks is the best course of action, but other factors, such as smoking, excessive alcohol, sun exposure without adequate sunscreen, obesity, and inactivity “are more likely to increase one’s risk for cancer,” Dr. Shepard said.

In a statement from the U.K.-based Science Media Centre, Pauline Emmett, PhD, from the University of Bristol (England), commented that this is a “good-quality” study and “the authors have been very careful not to speculate.”

“The main limitation is that this is observational data which provides associations which suggest a relationship but cannot tell if it is causal,” Dr. Emmett said. However, “we know from a body of evidence that it is worth thinking twice before choosing to drink sugar-sweetened beverages every day.”

The study had no commercial funding. Dr. Zhao, Dr. Zhang, Dr. Reau, and Dr. Shepard reported no relevant financial relationships. Dr. Emmett is a member of the European Food Safety Authority working group on dietary sugars.

The new study was published online in JAMA.

About 40% of people with liver cancer do not have one of the well-known disease risk factors, such as chronic hepatitis B or C infection, type 2 diabetes, or obesity. In the current analysis, Dr. Zhao and colleagues wanted to determine whether sugar-sweetened or artificially sweetened beverages, consumed by a large swath of the population, could be a risk factor for liver cancer or chronic liver disease.

Two previous studies have found only a “potential association” between sugar-sweetened beverage intake and a person’s risk for liver cancer, the authors explained.

In July, the International Agency for Research on Cancer officially classified the artificial sweetener aspartame as a possible carcinogen, but cancer epidemiologist Paul Pharoah, MD, PhD, commented that “the evidence that aspartame causes primary liver cancer, or any other cancer in humans, is very weak.”

To provide greater clarity about a potential link, the study team used the Women’s Health Initiative to evaluate sugary beverage consumption among 98,786 postmenopausal women and artificially sweetened drink intake among 64,787 followed for up to a median of 20.9 years. The primary outcomes were liver cancer incidence and mortality from chronic liver disease, defined as nonalcoholic fatty liver disease, liver fibrosis, cirrhosis, alcoholic liver diseases, and chronic hepatitis.

Among these women, nearly 7% consumed at least one sugar-sweetened beverage daily and 13% consumed one or more artificially sweetened beverage servings daily.

Over the follow-up period, 207 women developed liver cancer and 148 died from chronic liver disease in the sugary beverage group while 133 women developed liver cancer and 74 died from chronic liver disease in the artificial sugar group.

Compared with women consuming three servings or fewer of sugar-sweetened beverages per month, those consuming one or more servings per day had a significantly higher risk for liver cancer (18.0 vs. 10.3 per 100,000; adjusted hazard ratio, 1.85; P = .01) and for chronic liver disease mortality (17.7 vs. 7.1 per 100,000; aHR, 1.68; P = .04).

Compared with women consuming three servings or fewer of artificially sweetened beverages per month, those drinking one or more servings per day did not have a significantly increased risk for liver cancer (11.8 vs. 10.2 per 100,000; aHR, 1.17; P = .55) or chronic liver disease mortality (7.1 vs. 5.3 per 100,000; aHR 0.95; P = .88).

The authors noted several limitations to the study, including not tracking potential changes in beverage consumption over time or details on the specific sugar content or sweetener types consumed.

Corresponding author Xuehong Zhang, ScD, also with Brigham and Women’s Hospital and Harvard Medical School, said it’s not surprising that sugar-sweetened beverages may raise the risk of adverse liver outcomes.

“Intake of sugar-sweetened beverage[s], a postulated risk factor for obesity, diabetes, and cardiovascular disease, may drive insulin resistance and inflammation, which are strongly implicated in liver carcinogenesis and liver health,” Dr. Zhang said in an interview.

The lack of an association between artificially sweetened beverages and liver outcomes is also not particularly surprising, Dr. Zhang said, “given that the consumption level of artificially sweetened beverages is low, the sample size is relatively small,” and “the dose response relationship remains unknown.”

Nancy S. Reau, MD, who was not involved in the research, said the authors should be “congratulated for trying to clarify liver-related health risk related to artificial or sugar-sweetened beverages.”

In her view, the most important finding is the association between daily consumption of sugar-sweetened beverages and liver health.

“Regardless of whether this is a surrogate marker for liver disease risk (such as fatty liver disease) or a consequence of the drink itself, it is an easy measure for clinicians to capture and an easy behavior for patients to modify,” Dr. Reau, a hepatologist at Rush Medical College, Chicago, said in an interview.

However, Dr. Reau noted, “I do not feel that this article can be used to advocate for artificially sweetened beverages as a substitute.”

It is possible, she explained, that this population was too small to see a significant signal between artificially sweetened beverages and liver health. Plus, “natural, low-caloric beverages as part of a healthy diet combined with exercise are always going to be ideal.”

Weighing in as well, Dale Shepard, MD, PhD, a medical oncologist at the Cleveland Clinic, noted that “this is another study that points to the need for moderation.”

In his view, avoiding excess consumption of sugary or artificially sweetened drinks is the best course of action, but other factors, such as smoking, excessive alcohol, sun exposure without adequate sunscreen, obesity, and inactivity “are more likely to increase one’s risk for cancer,” Dr. Shepard said.

In a statement from the U.K.-based Science Media Centre, Pauline Emmett, PhD, from the University of Bristol (England), commented that this is a “good-quality” study and “the authors have been very careful not to speculate.”

“The main limitation is that this is observational data which provides associations which suggest a relationship but cannot tell if it is causal,” Dr. Emmett said. However, “we know from a body of evidence that it is worth thinking twice before choosing to drink sugar-sweetened beverages every day.”

The study had no commercial funding. Dr. Zhao, Dr. Zhang, Dr. Reau, and Dr. Shepard reported no relevant financial relationships. Dr. Emmett is a member of the European Food Safety Authority working group on dietary sugars.

A woman’s quest to become pregnant resulted in lead poisoning from an Ayurvedic treatment. The case triggered the seizure of pills from an Ontario natural-products clinic and the issuance of government warnings about the risks of products from this business, according to a new report.

The case highlights the need for collaboration between clinicians and public health authorities to address the potential health risks of supplements, including the presence of lead and other metals in Ayurvedic products, according to the report.

“When consumer products may be contaminated with lead, or when lead exposure is linked to sources in the community, involving public health can facilitate broader actions to reduce and prevent exposures to other people at risk,” wrote report author Julian Gitelman, MD, MPH, a resident physician at the University of Toronto Dalla Lana School of Public Health, and colleagues.

Their case study was published in the Canadian Medical Association Journal.

The researchers detailed what happened after a 39-year-old woman sought medical care for abdominal pain, constipation, nausea, and vomiting. The woman underwent a series of tests, including colonoscopy, laparoscopy, and biopsies of bone marrow and ovarian cysts.

Only later did clinicians home in on the cause of her ailments: the Ayurvedic medications that the patient had been taking daily for more than a year for infertility. Her daily regimen had varied, ranging from a few pills to a dozen pills.

Heavy metals are sometimes intentionally added to Ayurvedic supplements for perceived healing properties, wrote the authors. They cited a previous study of a sample of Ayurvedic pills bought on the Internet from manufacturers based in the United States and India that showed that 21% contained lead, mercury, or arsenic.

A case report published last year in German Medical Weekly raised the same issue.
 

Melatonin gummies

Regulators in many countries struggle to help consumers understand the risks of natural health supplements, and the challenge extends well beyond Ayurvedic products.

There has been a “huge and very troubling increase” in U.S. poison control calls associated with gummy-bear products containing melatonin, said Canadian Senator Stan Kutcher, MD, at a May 11 meeting of Canada’s Standing Senate Committee on Social Affairs, Science, and Technology.

In April, JAMA published a U.S. analysis of melatonin gummy products, Dr. Kutcher noted. In this research letter, investigators reported that one product did not contain detectable levels of melatonin but did contain 31.3 mg of cannabidiol.

In other products, the quantity of melatonin ranged from 74% to 347% of the labeled quantity. A previous Canadian study of 16 melatonin brands found that the actual dose of melatonin ranged from 17% to 478% of the declared quantity, the letter noted.

The May 11 Senate meeting provided a forum for many of the recurring debates about supplements, which also are known as natural health products.

Barry Power, PharmD, editor in chief for the Canadian Pharmacists Association, said that his group was disappointed when Canada excluded natural health products from Vanessa’s Law, which was passed in 2014. This law sought to improve the reporting of adverse reactions to drugs.

“We’re glad this is being revisited now,” Dr. Power told the Senate committee. “Although natural health products are often seen as low risk, we need to keep in mind that ‘low risk’ does not mean ‘no risk,’ and ‘natural’ does not mean ‘safe.’ ”

In contrast, Aaron Skelton, chief executive of the Canadian Health Food Association, spoke against this bid to expand the reach of Vanessa’s Law into natural health products. Canadian lawmakers attached provisions regarding increased oversight of natural health products to a budget package instead of considering them as part of a stand-alone bill.

“Our concern is that the powers that are being discussed have not been reviewed and debated,” Mr. Skelton told Dr. Kutcher. “The potential for overreach and unnecessary regulation is significant, and that deserves debate.”

“Profits should not trump Canadians’ health,” answered Dr. Kutcher, who earlier served as head of the psychiatry department at Dalhousie University in Halifax, N.S.

By June, Vanessa’s Law had been expanded with provisions that address natural health products, including the reporting of products that present a serious risk to consumers.
 

Educating consumers

Many consumers overestimate the level of government regulation of supplements, said Pieter A. Cohen, MD, leader of the Supplement Research Program at Cambridge Health Alliance in Massachusetts. Dr. Cohen was the lead author of the JAMA research letter about melatonin products.

Supplements often share shelves in pharmacies with medicines that are subject to more strict regulation, which causes confusion.

“It’s really hard to wrap your brain around [the fact] that a health product is being sold in pharmacies in the United States and it’s not being vetted by the FDA [U.S. Food and Drug Administration]”, Dr. Cohen said in an interview

The confusion extends across borders. Many consumers in other countries will assume that the FDA performed premarket screening of U.S.-made supplements, but that is not the case, he said.

People who want to take supplements should look for reputable sources of information about them, such as the website of the National Institutes of Health’s Office of Dietary Supplements, Dr. Cohen said. But patients often forget or fail to do this, which can create medical puzzles, such as the case of the woman in the Ontario case study, said Peter Lurie, MD, MPH, executive director of the nonprofit Center for Science in the Public Interest, which has pressed for increased regulation of supplements.

Clinicians need to keep in mind that patients may need prodding to reveal what supplements they are taking, he said.

“They just think of them as different, somehow not the province of the doctor,” Dr. Lurie said. “For others, they are concerned that the doctors will disapprove. So, they hide it.”

Isometric exercise training emerged as the most effective mode to reduce blood pressure in a systematic review and meta-analysis of 270 randomized trials with close to 16,000 participants.

The findings support the development of new exercise guidelines for blood pressure control, the authors said.

Previous research, based on older data that excluded high-intensity interval training (HIIT) and isometric exercise training (IET), led to aerobic exercise training (AET) being recommended for managing blood pressure, according to the authors.

Although AET, HIIT, dynamic resistance training (RT), and combined training (CT) are also effective in reducing both systolic and diastolic blood pressure, the new analysis suggests that IET does it best.

The analysis showed reductions in blood pressure of 8.24/4 mm Hg after IET, compared with 4.49/2.53 mm Hg after AET; 4.55/3.04 mm Hg after RT; 6.04/2.54 mm Hg after CT; and 4.08/2.50 mm Hg after HIIT.

“These findings mirror our smaller-scale trials, and therefore we anticipated that isometrics would be largely effective,” Jamie O’Driscoll, PhD, of Canterbury (England) Christ Church University, said in an interview. However, “the magnitude of difference between isometrics and some other modes was surprising.”

The study was published online in the British Journal of Sports Medicine.
 

All modes effective

The investigators analyzed data from 270 randomized controlled trials including 15,827 people published between 1990 and February 2023. For consistency, the protocol/intensity of each included paper was screened against the Exercise Prescription in Everyday Practice and Rehabilitative Training tool to be defined and categorized.

All protocols were then stratified as AET, RT, CT, HIIT or IET.

As appropriate, protocols were then further stratified into subgroups: AET included walking, running, and cycling; HIIT included sprint interval training and aerobic interval training; and IET included isometric leg extension and isometric wall squat.

Healthy resting blood pressure was defined as a reading below 130/85 mm Hg, prehypertension as 130-139/85-89 mm Hg, and hypertension as 140/90 mm Hg or higher.

All exercise modes led to statistically significant reductions in systolic BP in normal blood pressure cohorts; however, all reductions were substantially larger in individuals with hypertension.

Pairwise analyses showed significant reductions in resting systolic BP and diastolic BP following AET (−4.49/–2.53 mm Hg); RT (–4.55/–3.04 mm Hg), CT (–6.04/–2.54 mm Hg), HIT (–4.08/–2.50 mm Hg); and IET (–8.24/–4.00 mm Hg).

In the network meta-analysis, the rank order of effectiveness for systolic BP based on surface under the cumulative ranking curve values were IET (SUCRA: 98.3%), CT (75.7%), RT (46.1%), AET (40.5%), and HIIT (39.4%).

Secondary network meta-analyses showed that isometric wall squat was the most effective submode for reducing systolic BP (90.4%), followed by isometric leg extension, isometric hand grip, cycling, running, CT, sprint interval training, other aerobic, RT, aerobic interval training, and walking.

Running was the most effective submode for lowering diastolic BP (91.3%), followed by isometric wall squat, isometric handgrip, isometric leg extension, cycling, sprint interval training, RT, AIT, other aerobic, CT, and walking.

The authors acknowledged limitations, including variability in exercise interventions, missing data, variable quality of exercise monitoring and analyses, lack of blinding to group allocation, varying participant populations, and publication bias.

Nevertheless, they concluded, “the results of this analysis should inform future exercise guideline recommendations for the prevention and treatment of arterial hypertension.”
 

Guideline changing?

“There are numerous organizations involved in providing and communicating population exercise guidelines,” including World Health Organization, American and European exercise guidelines, and the National Institute for Health and Care Excellence, Dr. O’Driscoll said. “We are currently developing an international collaborative project with other world leaders in the area to develop this line of enquiry.”

In addition, the team is exploring the prescription of IET within England’s National Health Service and extending the study to wider clinical populations.

In a comment, John A. Osborne, MD, PhD, founder and director of State of the Heart Cardiology in Southlake, Tex., said: “This study further lends credence that other forms of exercise, beyond the usually recommended aerobic exercise promulgated in prior guidelines, have significant value for blood pressure lowering, and, potentially, may offer even greater benefits for ... controlling hypertension.”

“This study should inform contemporary nonpharmacological approaches to blood pressure management and allows providers more flexibility in different strategies of exercise to combat high blood pressure,” said Dr. Osborne, a volunteer spokesperson for the American Heart Association.

That said, “while this study by itself is extremely provocative, thoughtful, and rigorously performed, it should be used as hypothesis generating and hopefully [will be followed by] head-to-head studies of aerobic exercise versus resistance training to confirm the findings.”

The study received no funding. Dr. O’Driscoll and Dr. Osborne reported no relevant financial relationships.

As appropriate, protocols were then further stratified into subgroups: AET included walking, running, and cycling; HIIT included sprint interval training and aerobic interval training; and IET included isometric leg extension and isometric wall squat.

Healthy resting blood pressure was defined as a reading below 130/85 mm Hg, prehypertension as 130-139/85-89 mm Hg, and hypertension as 140/90 mm Hg or higher.

All exercise modes led to statistically significant reductions in systolic BP in normal blood pressure cohorts; however, all reductions were substantially larger in individuals with hypertension.

Pairwise analyses showed significant reductions in resting systolic BP and diastolic BP following AET (−4.49/–2.53 mm Hg); RT (–4.55/–3.04 mm Hg), CT (–6.04/–2.54 mm Hg), HIT (–4.08/–2.50 mm Hg); and IET (–8.24/–4.00 mm Hg).

In the network meta-analysis, the rank order of effectiveness for systolic BP based on surface under the cumulative ranking curve values were IET (SUCRA: 98.3%), CT (75.7%), RT (46.1%), AET (40.5%), and HIIT (39.4%).

Secondary network meta-analyses showed that isometric wall squat was the most effective submode for reducing systolic BP (90.4%), followed by isometric leg extension, isometric hand grip, cycling, running, CT, sprint interval training, other aerobic, RT, aerobic interval training, and walking.

Running was the most effective submode for lowering diastolic BP (91.3%), followed by isometric wall squat, isometric handgrip, isometric leg extension, cycling, sprint interval training, RT, AIT, other aerobic, CT, and walking.

The authors acknowledged limitations, including variability in exercise interventions, missing data, variable quality of exercise monitoring and analyses, lack of blinding to group allocation, varying participant populations, and publication bias.

Nevertheless, they concluded, “the results of this analysis should inform future exercise guideline recommendations for the prevention and treatment of arterial hypertension.”
 

Guideline changing?

“There are numerous organizations involved in providing and communicating population exercise guidelines,” including World Health Organization, American and European exercise guidelines, and the National Institute for Health and Care Excellence, Dr. O’Driscoll said. “We are currently developing an international collaborative project with other world leaders in the area to develop this line of enquiry.”

In addition, the team is exploring the prescription of IET within England’s National Health Service and extending the study to wider clinical populations.

In a comment, John A. Osborne, MD, PhD, founder and director of State of the Heart Cardiology in Southlake, Tex., said: “This study further lends credence that other forms of exercise, beyond the usually recommended aerobic exercise promulgated in prior guidelines, have significant value for blood pressure lowering, and, potentially, may offer even greater benefits for ... controlling hypertension.”

“This study should inform contemporary nonpharmacological approaches to blood pressure management and allows providers more flexibility in different strategies of exercise to combat high blood pressure,” said Dr. Osborne, a volunteer spokesperson for the American Heart Association.

That said, “while this study by itself is extremely provocative, thoughtful, and rigorously performed, it should be used as hypothesis generating and hopefully [will be followed by] head-to-head studies of aerobic exercise versus resistance training to confirm the findings.”

The study received no funding. Dr. O’Driscoll and Dr. Osborne reported no relevant financial relationships.

A novel triple agonist to receptors for three nutrient-stimulated hormones led to weight loss as high as 24% among people with overweight or obesity but who did not have type 2 diabetes when used at the highest tested dose for 48 weeks. The results are from a phase 2 study of retatrutide that was published in The New England Journal of Medicine (2023 Aug 10. doi: 10.1056/NEJMoa2301972).

This level of weight loss is “unprecedented” for a medication administered for 48 weeks, Mary-Elizabeth Patti, MD, said in an editorial that accompanied the report.

The findings “offer further optimism ... that effective pharmacologic management of obesity and related disorders is possible,” wrote Dr. Patti, a principal investigator at the Joslin Diabetes Center in Boston.

The study randomly assigned 338 adults with obesity or overweight – a body mass index (BMI) of ≥ 27 kg/m² – and at least one weight-related complication to receive either weekly subcutaneous injections of retatrutide in any of six dose regimens or placebo over 48 weeks. The primary outcome was weight change from baseline after 24 weeks.

The highest dose of retatrutide safely produced an average 17.5% drop from baseline weight, compared with an average 1.6% reduction in the placebo group, after 24 weeks, a significant difference.

After 48 weeks, the highest retatrutide dose safely cut baseline weight by an average of 24.2%, compared with an average 2.1% drop among placebo control patients, Ania M. Jastreboff, MD, PhD, and her coauthors wrote in their report. Weight loss levels after 24 and 48 weeks of retatrutide treatment followed a clear dose-response pattern.
 

Weight losses never before seen

“I have never seen weight loss at this level” after nearly 1 year of treatment, Dr. Jastreboff said when she discussed these findings in a press conference at the annual scientific sessions of the American Diabetes Association in San Diego in late June.

A separate presentation at the ADA meeting documented unprecedented weight loss levels in a study of 281 people with obesity or overweight and type 2 diabetes.

“No other medication has shown an average 17% reduction from baseline bodyweight after 36 weeks in people with type 2 diabetes,” said Julio Rosenstock, MD, director of the Dallas Diabetes Research Center at Medical City, Texas, who formally presented the results from the study of retatrutide in people with type 2 diabetes at the ADA meeting.

The mechanism behind retatrutide’s potent weight-loss effect seems likely tied to its action on three human receptors that naturally respond to three nutrient-stimulated hormones that control appetite, metabolism, fat mobilization, and related functions.

The three hormones that the retatrutide molecule simultaneously mimics are glucagon-like peptide-1 (GLP-1), such as agents in the class of GLP-1 agonists that includes liraglutide (Victoza/Saxenda) and semaglutide (Ozempic/Wegovy); the glucose-dependent insulinotropic polypeptide (GIP), the receptor that is also activated by tirzepatide (Mounjaro), a dual-incretin receptor agonist that mimics both GLP-1 and GIP; and glucagon. Survodutide is a dual GLP-1 and glucagon receptor agonist in phase 2 development.

Retatrutide is currently unique among agents with reported clinical results by having agonist effects on the receptors for all three of these hormones, a property that led Dr. Patti to call retatrutide a “triple G” hormone-receptor agonist in her editorial.
 

Triple agonist has added effect on liver fat clearance

The glucagon-receptor agonism appears to give retatrutide added effects beyond those of the GLP-1 agonists or GLP-1/GIP dual agonists that are increasingly used in U.S. practice.

A prespecified subgroup analysis of the no diabetes/Jastreboff study (but that was not included in the NEJM report) showed that at both 8-mg and 12-mg weekly doses, 24 weeks of retatrutide produced complete resolution of excess liver fat (hepatic steatosis) in about 80% of the people eligible for the analysis (those whose liver volume was at least 10% fat at study entry).

That percentage increased to about 90% of people receiving these doses after 48 weeks, Lee M. Kaplan, MD, reported during a separate presentation at the ADA meeting.

“When you add glucagon activity, liver-fat clearance goes up tremendously,” observed Dr. Kaplan, director of the Obesity, Metabolism and Nutrition Institute at Massachusetts General Hospital in Boston.

The average age of the participants in the new study of the use of retatrutide for those with obesity/overweight but not diabetes was 48 years. By design, 52% were men. (The study sought to enroll roughly equal numbers of men and women.) Average BMI at study entry was 37 kg/m².

Treatment with retatrutide was also significantly associated with improvements in several cardiometabolic measures in exploratory analyses, including systolic and diastolic blood pressure, A1c, fasting glucose, insulin, and some (but not all) lipids, Dr. Jastreboff, director of the Yale Obesity Research Center of Yale University in New Haven, Conn., and her coauthors reported in the NEJM article.

The safety profile of retatrutide was consistent with reported phase 1 findings for the agent among people with type 2 diabetes and resembled the safety profiles of other agents based on GLP-1 or GIP–GLP-1 mimicry for the treatment of type 2 diabetes or obesity.

The most frequently reported adverse events from retatrutide were transient, mostly mild to moderate gastrointestinal events. They occurred primarily during dose escalation. Discontinuation of retatrutide or placebo because of adverse events occurred in 6% to 16% of the participants who received retatrutide and in none of the participants who received placebo.

Lilly, the company developing retatrutide, previously announced the launch of four phase 3 trials to gather further data on retatrutide for use in a marketing-approval application to the Food and Drug Administration.

The four trials – TRIUMPH-1, TRIUMPH-2, TRIUMPH-3, and TRIUMPH-4 – are evaluating the safety and efficacy of retatrutide for chronic weight management for those with obesity or overweight, including those who also have obstructive sleep apnea, knee osteoarthritis, type 2 diabetes, or cardiovascular disease.

The study was sponsored by Lilly, the company developing retatrutide. Dr. Patti has been a consultant to AstraZeneca, Dexcom, Hanmi, and MBX. She has received funding from Dexcom and has been a monitor for a trial funded by Fractyl. Dr. Jastreboff, Dr. Kaplan, and Dr. Rosenstock have reported financial relationships with Lilly as well as other companies.

Point-of-care ultrasound (POCUS) is integral to the delivery of high-quality patient care. The benefits of POCUS for timely diagnosis and procedural assistance are well documented. With continued innovation, its novel benefits can extend to the upper airway evaluation in both inpatient and outpatient settings.

Adi et al notes that POCUS can serve as an adjunct to traditional airway checklists and help intensivists/anesthesiologists identify potentially difficult laryngoscopies, choose the correct endotracheal tube size to reduce the risk of subglottic stenosis, and help confirm appropriate endotracheal tube placement (Adi, et al. J Emerg Crit Care Med. 2019;3:31).

The prediction of a difficult airway is a potentially lifesaving use for this technology. The authors note that smaller studies demonstrate promising results in four techniques: the inability to visualize the hyoid bone using the sublingual approach, a shorter hyomental distance in morbidly obese patients, anterior neck thickness at different anatomical levels (vocal cords, hyoid bone, and thyroid membrane), and a tongue thickness of more than 6.1 cm from the submental approach were all capable of predicting difficult tracheal intubation with varying degrees of sensitivity and specificity.

In the outpatient setting, an understanding of the upper airway anatomy can help with sleep apnea screenings. Korotun, et al. demonstrated in a small sample that ultrasound evaluation of hyoid bone excursion during hypoglossal nerve stimulation may be a useful tool to predict response to therapy and guide hypoglossal nerve stimulator settings (Korotun, et al. Sleep. 2020;43[Suppl_1]:A247-A248).Upper airway ultrasound is easy to learn. The anatomical landmarks are similar in most patients. This convenient tool can be added to your patient care repertoire in a variety of clinical settings.

Goals-of-care discussions are essential to management of the intensive care unit (ICU) patient. Racial inequities in end-of-life decision making have been documented for many years, with literature demonstrating that marginalized populations are less likely to have EHR-documented goals-of-care discussions and more likely to have concerns regarding clinician communication.

A recently published randomized control trial in JAMA highlights an intervention that offers promise in addressing disparities in goals-of-care conversations. Curtis, et al. studied whether priming physicians with a communication guide advising on discussion prompts and language for goals-of-care could improve the rate of documented goals-of-care discussions among hospitalized older adults with serious illness. The study found that for patients in the intervention arm, there was a significant increase in proportion of goals-of-care discussions within 30 days. Notably, the difference in documented goals-of-care discussions between arms was greater in the subgroup of patients from underserved groups (Curtis JR, et al. JAMA. 2023;329[23]:2028-37).

Nevertheless, while interventions may help increase the rate of goals-of-care discussions, it is also important to address the content of discussions themselves. You and colleagues recently published a mixed-methods study assessing the impact of race on shared decision-making behaviors during family/caregiver meetings. The authors found that while ICU physicians approached shared decision making with White and Black families similarly, Black families felt their physicians provided less validation of the family role in decision making than White families did (You H, et al. Ann Am Thorac Soc. 2023 May;20[5]:759-62). These findings highlight the importance of ongoing work that focuses not only on quantity but also on quality of communication regarding goals-of-care for patients from diverse backgrounds.

Ann Am Thorac Soc. 2023 May;20[5]:759-62). These findings highlight the importance of ongoing work that focuses not only on quantity but also on quality of communication regarding goals-of-care for patients from diverse backgrounds.

Frailty, a concept that originated in the geriatric population, is a state of vulnerability resulting from a decline in reserve and function across physiological systems. While it is more commonly observed in older adults, some aging-associated syndromes, such as sarcopenia, impaired cognition, inflammation, and malnutrition, may be present in younger patients with end-stage organ disease. These syndromes can be associated with biological age, as opposed to chronological age, which explains why younger patients with end-stage organ disease can develop frailty (Schaenman JM, et al. Am J Transplant. 2021 Jun;21[6]:2018-24). Frailty in the lung transplant population is associated with increased morbidity and mortality while on the waitlist and post-transplant (Montgomery E, et al. J Transplant. 2020 Aug 7:3239495). In 2021, the International Society of Heart and Lung Transplantation recommended including a frailty assessment to complete a patient’s transplant evaluation. The committee cautioned using current assessment tools, as they are not yet accepted as the standard of care (Leard, et al. J Heart Lung Transplant. 2021 Nov;40[11]:1349-79). Existing tools being used evolved from studies of community-dwelling older adults with no predilection for distinct organ disease, which include the Fried Physical Frailty Phenotype (FPFP) and the Short Physical Performance Battery (SPPB). Along with physical limitations, frail patients tend to have abnormal biomarkers including higher inflammatory cytokines, such as plasma IL-6 and tumor necrosis factor receptor 1, and lower insulin-like growth factor I and leptin (Singer JP, et al. Am J Respir Crit Care Med. 2015;192[11]1325-34). The concept of a lung-focused approach to frailty, which considers biomarkers and body composition, is currently being researched (Singer JP, et al. J Heart Lung Transplant. 2023;S1053-S2498[23]00049-9). This disease-specific frailty scale would identify lung transplant candidates who may benefit from targeted interventions, and such frailty would also be expected to improve after transplant.

Airway Disorders Network

Bronchiectasis Section

Bronchiectasis is a chronic inflammatory lung disease characterized by the progressive destruction of the airways and persistent inflammation. In bronchiectasis, excessive neutrophil accumulation in the airways leads to release of neutrophil serine proteases (NSPs), which contributes to tissue damage and perpetuates the inflammatory process in the lungs. The three main NSPs include neutrophil elastase (NE), proteinase3, and cathepsin G. Elevations in NE activity in sputum in NCFBE are associated with increased exacerbations and declines in lung function. Dipeptidyl peptidase 1 (DPP1), an enzyme primarily found in neutrophils, is responsible for activating NSPs during neutrophil maturation. In bronchiectasis, increased DPP1 activity results in an augmented production of active NSPs, exacerbating lung damage and inflammation.

Brensocatib, an oral, reversible inhibitor of DPP1 is currently being developed as a novel approach to managing bronchiectasis. Brensocatib was evaluated in a phase 2 clinical trial (WILLOW), a randomized, double-blind, placebo-controlled trial involving adults with non–cystic fibrosis bronchiectasis (NCFBE). Treatment with brensocatib for 24 weeks significantly prolonged the time to the first exacerbation at both the 10 mg and 25 mg doses and lowered the risk of exacerbation by 40% relative to placebo. The treatment was well tolerated, with no significant safety concerns. Results of a recent post hoc analysis from the WILLOW study show that brensocatib effectively reduces exacerbations and slows lung function decline across different severities of bronchiectasis. These findings suggest that brensocatib holds potential as the 1st new therapeutic option for patients with NCFBE, with currently no FDA-approved drugs. Results of a larger-scale phase 3 trial are awaited later this year, which will hopefully confirm these results and ascertain the long-term safety.
