Clinician Reviews

Use of the epidermal growth-factor receptor inhibitor erlotinib led to about a 30% reduction in duodenal polyp burden after 6 months of once-weekly treatment for patients with familial adenomatous polyposis (FAP) in a phase 2 clinical trial.

“If existing data are confirmed and extended through future research, this strategy has the potential for substantial impact on clinical practice by decreasing, delaying, or augmenting endoscopic and surgical interventions as the mainstay for duodenal cancer prevention in this high-risk patient population,” the study team says.

FAP is a rare genetic condition that markedly raises the risk for colorectal polyps and cancer.

“The biological pathway that leads to the development of polyps and colon cancer in patients with FAP is the same biological pathway as patients in the general population,” study investigator Niloy Jewel Samadder, MD, with the Mayo Clinic, Rochester, Minn., said in a news release.

“Our trial looked at opportunities to use chemoprevention agents in patients with FAP to inhibit the development of precancerous polyps in the small bowel and colorectum,” Dr. Samadder explains.

In an earlier study, the researchers found that the combination of the COX-2 inhibitor sulindac (150 mg twice daily) and erlotinib (75 mg daily) reduced duodenal polyp burden.

However, the dual-drug strategy was associated with a relatively high adverse event (AE) rate, which may limit use of the combination for chemoprevention, as reported previously.

This phase 2 study tested whether erlotinib’s AE profile would be improved with a once-weekly dosing schedule while still reducing polyp burden.

The study was first published online in the journal Gut.

In the single-arm, multicenter study, 46 adults with FAP (mean age, 44 years; 48% women) self-administered 350 mg of erlotinib by mouth one time per week for 6 months. All but four participants completed the 6-month study.

After 6 months of weekly erlotinib, duodenal polyp burden was significantly reduced, with a mean percent reduction of 29.6% (95% confidence interval: –39.6% to –19.7%; P < .0001).

The benefit was observed in patients with either Spigelman 2 or Spigelman 3 duodenal polyp burden.

“Though only 12% of patients noted a decrease in Spigelman stage from 3 to 2 associated with therapy, the majority of patients (86%) had stable disease while on treatment,” the study team reports.

GI polyp number (a secondary outcome) was also decreased after 6 months of treatment with erlotinib (median decrease of 30.8%; P = .0256).

While once-weekly erlotinib was “generally” well tolerated, grade 2 or 3 AEs were reported in 72% of patients; two suffered grade 3 toxicity. Nonetheless, the AE rate was significantly more than the expected null hypothesis rate of 50%, the study team states.

Four patients withdrew from the study because of drug-induced AEs, which included grade 3 rash acneiform, grade 2 infections (hand, foot, and mouth disease), grade 1 fatigue, and grade 1 rash acneiform. No grade 4 AEs were reported.

The most common AE was an erlotinib-induced acneiform-like rash, which occurred in 56.5% of study patients. The rash was managed with topical cortisone and/or clindamycin. Additional erlotinib-induced AEs included oral mucositis (6.5%), diarrhea (50%), and nausea (26.1%).

Summing up, Dr. Samadder and colleagues note that FAP “portends a heritable, systemic predisposition to cancer, and the ultimate goal of cancer preventive intervention is to interrupt the development of neoplasia, need for surgery, and ultimately death from cancer, with an acceptable AE profile.”

The findings from this phase 2 trial support further study of erlotinib as “an effective, acceptable cancer preventive agent for FAP-associated gastrointestinal polyposis,” they conclude.

The study was sponsored by the National Cancer Institute. Dr. Samadder is a consultant for Janssen Research and Development, Recursion Pharmaceuticals, and Cancer Prevention Pharmaceuticals.

In patients with moderate-to-severe atopic dermatitis, abrocitinib showed consistent treatment responses and no new safety issues, whether or not they had already been treated with the biologic dupilumab, an industry-sponsored study reports.

“In this post hoc analysis, both the efficacy and the safety profiles of abrocitinib were consistent in patients with moderate-to-severe atopic dermatitis, regardless of prior biologic therapy use,” lead author Melinda Gooderham, MD, medical director of the SKiN Centre for Dermatology, Peterborough, Ont., said during an oral presentation at the Society for Investigative Dermatology (SID) 2022 Annual Meeting.

“These results ... support the use of abrocitinib in patients who might have received biologic therapy prior,” she added.

“Prior biologic use did not reveal any new safety signals ... keeping in mind the key limitation of this analysis is that it was done post hoc,” she noted.

Guidelines for moderate-to-severe atopic dermatitis refractory to topical or systemic therapy include systemic immunosuppressants and dupilumab, a monoclonal antibody that inhibits interleukin-4 and interleukin-13 cytokine-induced responses, Dr. Gooderham said.

The Food and Drug Administration recently approved abrocitinib, an oral once-a-day Janus kinase 1 (JAK1) inhibitor, to treat the disease. The approval came with a boxed warning about increased risk for serious infections, mortality, malignancy, and lymphoproliferative disorders, major adverse cardiovascular events, thrombosis, and laboratory abnormalities.
 

Comparing the bio-experienced with the bio-naive

Dr. Gooderham and colleagues investigated whether patients who’d been treated with a biologic would respond to abrocitinib differently than patients who had not received prior biologic treatment.

Researchers pooled data from two phase 3 placebo-controlled trials of abrocitinib that led to approval and an earlier phase 2b study. They identified 67 patients previously treated with dupilumab and 867 patients who were bio-naive. They repeated their analysis using data from another phase 3 study of abrocitinib on 86 patients previously treated with dupilumab and 1,147 who were bio-naive. On average, the bio-experienced patients were in their mid-30s to early 40s, and the bio-naive group was several years younger.

In the pooled phase 2b and phase 3 JADE MONO-1 and JADE MONO-2 monotherapy trials, patients received once-daily abrocitinib 100 or 200 mg or placebo for 12 weeks. In the phase 3 JADE REGIMEN, which they analyzed separately, eligible patients were enrolled in a 12-week open-label run-in period during which they received an induction treatment of abrocitinib 200 mg once a day.

Researchers compared results of two assessments: the IGA (Investigator Global Assessment) and EASI-75 (Eczema Area and Severity Index, 75% or greater improvement from baseline).

• At week 12, IGA 0/1 dose-dependent response rates were similar in the pooled groups, regardless of whether they had received prior biologic therapy. With abrocitinib 200 mg, 43.5% of those with prior dupilumab therapy responded versus 41.4% of bio-naive patients; with abrocitinib 100 mg, 24.1% versus 26.7% responded. In JADE REGIMEN, corresponding response rates with abrocitinib 200 mg were 53.5% versus 66.9%, respectively.
• At week 12, EASI-75 responses were also comparable. In the pooled groups by dose, with abrocitinib 200 mg, EASI-75 response rates were 65.2% in patients with prior dupilumab therapy versus 62.4% in those without; at abrocitinib 100 mg, 34.5% versus 42.7% responded. Corresponding rates in JADE REGIMEN were 64.0% versus 76.4%, respectively.
• Treatment-emergent adverse event rates among patients with versus without prior biologic therapy were, respectively, 71.7% versus 69.9% (abrocitinib 200 mg + 100 mg groups) in the pooled population. Rates in JADE REGIMEN with abrocitinib 200 mg were, respectively, 66.3% versus 66.5%.
• Abrocitinib efficacy and safety were consistent in patients with moderate-to-severe atopic dermatitis, regardless of prior biologic therapy. Adverse events in the pooled monotherapy trials and in JADE REGIMEN included acne, atopic dermatitis, diarrhea, headache, nasopharyngitis, nausea, upper abdominal pain, and upper respiratory tract infection.

The authors acknowledge that the post hoc study design is a limitation and recommend confirming these findings in a large, long-term prospective study.
 

JAK inhibitors expand treatment options

The results will help doctors treat their patients, Jami L. Miller, MD, associate professor of dermatology and dermatology clinic medical director at Vanderbilt University Medical Center, Nashville, Tenn., told this news organization.

“Because JAK inhibitors have potentially more side effects than inhibitors of interleukin-4 and interleukin-13, in clinical practice most dermatologists are more likely to treat patients first with dupilumab or similar meds and step up to a JAK inhibitor if they do not respond,” she added in an email. 

“With more meds coming out to meet the needs of this population, this is an exciting time for patients with moderate-to-severe atopic dermatitis,” she commented.

Lindsay C. Strowd, MD, associate professor and vice chair of the department of dermatology at Wake Forest University, Winston-Salem, N.C., said JAK inhibitors are increasingly being studied and approved for use in various dermatologic diseases.

An oral JAK inhibitor (upadacitinib) is currently FDA approved for moderate-to-severe atopic dermatitis, and a topical JAK inhibitor (ruxolitinib) is also approved for use in atopic dermatitis, Dr. Strowd noted.

“The study results give providers important practical information,” added Dr. Strowd, who also was not involved with the study. “Those of us who care for patients with severe atopic dermatitis need to know how patients with prior biologic exposure will respond as newer agents come to market and the options for biologic use in atopic dermatitis continue to grow.”

The study was sponsored by Pfizer. All study authors have reported relevant financial relationships with, and several authors are employees of, Pfizer, the developer of abrocitinib. Dr. Strowd and Dr. Miller have reported no relevant financial relationships.

Fecal and mucosal microbiota have been the focus of much research. A study by Hou and colleagues that showed distinct differences in the intestinal and fecal microbiomes of patients with constipation-predominant or diarrhea-predominant IBS, compared with healthy controls, highlights the importance of a balanced and diverse microbiome to maintain a healthy gut. The article notes specific genera of microbiota that were associated with intestinal pain. When microbiota diversity is limited, the incidence of IBS is increased. This reinforces the importance of promoting a healthy microbiome in all patients and appreciating the correlation of the microbiome with the development of IBS.

 Internet-based cognitive-behavioral therapy may make it easier for patients to obtain therapy services. Kim and colleagues have shown this to be a cost-effective and efficacious way to deliver care. This care improves the quality of life for patients with IBS and is an effective intervention that is readily available. During pandemic times, the forum of online care also provides a safe way to deliver therapy services without the burden of the patient needing to commute to clinic and potentially be exposed to infectious disease. Given the relationship between IBS and psychiatric diagnoses noted by Creed and colleagues, it seems important to extend the availability of therapeutic interventions to as many patients with IBS as possible.

 Internet-based cognitive-behavioral therapy may make it easier for patients to obtain therapy services. Kim and colleagues have shown this to be a cost-effective and efficacious way to deliver care. This care improves the quality of life for patients with IBS and is an effective intervention that is readily available. During pandemic times, the forum of online care also provides a safe way to deliver therapy services without the burden of the patient needing to commute to clinic and potentially be exposed to infectious disease. Given the relationship between IBS and psychiatric diagnoses noted by Creed and colleagues, it seems important to extend the availability of therapeutic interventions to as many patients with IBS as possible.

New research suggests that regular physical activity can help lower the risk of COVID-19 infection and its severity, with a weekly tally of 150 minutes of moderate, or 75 minutes of vigorous, physical activity affording the best protection.

“Our findings highlight the protective effects of engaging in sufficient physical activity as a public health strategy, with potential benefits to reduce the risk of severe COVID-19,” say Antonio García-Hermoso, PhD, Public University of Navarra, Pamplona, Spain, and colleagues.

“Regular physical activity seemed to be related to a lower risk of COVID-19 infection, Dr. García-Hermoso said in an interview. “There is evidence that regular physical activity might contribute to a more effective immune response, providing enhanced protective immunity to infections, which could explain the relationship between exercise consistency with COVID-19 infection.”

Regular exercise may also help to boost the body’s anti-inflammatory responses, as well as cardiorespiratory and muscular fitness, all of which may explain its beneficial effects on COVID-19 severity, the researchers say.

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

Strong protection from COVID?

A growing body of evidence suggests that increased physical activity may modulate the course of COVID-19 infection and reduce the risk of poor outcomes. The new analysis is the first to systematically evaluate and pool data on the effect of regular physical activity on COVID-19 outcomes.

The findings are based on data from 16 studies with over 1.8 million adults (53% women, mean age 53 years).

Individuals who included regular physical activity in their weekly routine had an 11% lower risk for infection with SARS-CoV-2 (hazard ratio, 0.89; 95% confidence interval, 0.84-0.95), compared with inactive peers.

The physically active adults also had a 36% (HR, 0.64; 95% CI, 0.54-0.76) lower risk of being hospitalized, a 44% (HR, 0.66; 95% CI, 0.58-0.77) lower risk for severe COVID-19 illness, and a 43% (HR, 0.57; 95% CI, 0.46-0.71) lower risk of dying from COVID-19 than their inactive peers.

The greatest protective effect occurs with achieving at least 500 metabolic equivalent of task (MET) minutes per week of physical activity – equivalent to 150 minutes of moderate-intensity or 75 min of vigorous-intensity physical activity per week – with no added benefit beyond this level.

The researchers caution that the analysis included observational studies, differing study designs, subjective assessments of physical activity levels, and concerned only the Beta and Delta variants of SARS-CoV-2, not Omicron.

Despite these limitations, the researchers say their findings “may help guide physicians and health care policymakers in making recommendations and developing guidelines with respect to the degree of physical activity that can help reduce the risk of infectivity, hospitalization, severity, and mortality of COVID-19 at both the individual and the population level, especially in high-risk patients.”
 

Helpful, but not a panacea

Reached for comment, Sean Heffron, MD, a preventive cardiologist and assistant professor of medicine at NYU Langone Health, New York, said the study “supports the well-established nonlinear association of increasing physical activity with adverse outcomes from a diverse array of diseases, including infectious diseases, such as COVID-19.”

The observation is not particularly surprising, he said.

“It is as I would suspect. They compiled data from a large number of studies published over the past several years that all had consistent findings,” Dr. Heffron said.

“The take-away from a public health standpoint is that being physically active improves health in myriad ways. That being said, it is not a panacea, so additional measures (masking, vaccinations, etc.) are important for everyone,” he said.

Also weighing in, Joseph Herrera, DO, chair of the department of rehabilitation for Mount Sinai Health System, New York, said, “If you are physically fit, your body is more resilient and better prepared to handle the stressors of COVID or any other disease process.”

For now, however, the question of whether physical fitness is actually protective against COVID remains unclear. “I’m just not sure right now,” Dr. Herrera said in an interview.

He said he has treated athletes in professional sports – including the National Football League and Major League Baseball – and some of them have had long COVID and have not returned to play. “These are athletes at the peak of fitness and their career.”

Nonetheless, Dr. Herrera said a good public health message in general is to stay fit or get fit.

“That’s something I preach all the time,” he told this news organization.

Dr. García-Hermoso agreed. “In contrast to the vast majority of drugs, exercise is free of adverse effects. It’s time to consider exercise as medicine. It’s never too late to start being physically active.”

The study had no specific funding. Dr. García-Hermoso, Dr. Heffron, and Dr. Herrera have reported no relevant financial relationships.

Researchers in France have discovered monkeypox virus in anal samples of men with no symptoms of the disease, advancing the possibility that asymptomatic carriers may be hidden drivers of the global outbreak.

The findings, published in Annals of Internal Medicine, follow a similar, non–peer-reviewed report from Belgium. Researchers in both studies tested swabs for monkeypox in men who have sex with men. These swabs had been collected for routine STI screening.

It’s unclear whether asymptomatic individuals who test positive for monkeypox can spread the virus, the French team wrote. But if so, public health strategies to vaccinate those with known exposure “may not be sufficient to contain spread.”

In an editorial accompanying their paper, Stuart Isaacs, MD, associate professor at the University of Pennsylvania, Philadelphia, said it “raises the question of whether asymptomatic or subclinical infections are contributing to the current worldwide outbreak.”

Historically, transmission of monkeypox and its close relative, smallpox, was thought to be greatest when a rash was present, Dr. Isaacs wrote. “Long chains of human-to-human transmission were rare” with monkeypox.

That’s changed with the current outbreak, which was first detected in May. On Aug. 17, the World Health Organization reported more than 35,000 cases in 92 countries, with 12 deaths.
 

Research methods

For the French study, researchers conducted polymerase chain reaction tests on 200 anorectal swabs from asymptomatic individuals that had been collected from June 5 to July 11 in order to screen for gonorrhea and chlamydia. Of those, 13 (6.5%) were positive for monkeypox.

During the study period, STI testing had been suspended in individuals with monkeypox symptoms because of safety concerns, the researchers reported.

The research team contacted the 13 monkeypox-positive patients and advised them to limit sexual activity for 21 days following their test and notify recent sexual partners. None reported having developed symptoms, but two subsequently returned to the clinic with symptoms – one had an anal rash and the other a sore throat.

In the Belgian report, posted publicly on June 21 as a preprint, 3 of 224 anal samples collected for STI screening in May tested positive for monkeypox. All three of the men who tested positive said they did not have any symptoms in the weeks before and after the sample was taken.

At follow-up testing, 21-37 days after the initial samples were taken, all patients who had previously tested positive were negative. This was “likely as a consequence of spontaneous clearance of the infection,” the authors of that paper wrote.
 

Clinical implications of findings are uncertain

Monica Gandhi, MD, MPH, a professor of medicine at the University of California, San Francisco, said in an interview that the clinical implications of the findings are uncertain because it’s not known how much viral transmission results from asymptomatic individuals.

Nevertheless, Dr. Gandhi said that “vaccinating all gay men for monkeypox who will accept the vaccine is prudent,” compared with a less aggressive strategy of only vaccinating those with known exposure, which is called ring vaccination. That way, “we can be assured to provide immunity to large swaths of the at-risk population.”

Dr. Gandhi said that movement toward mass vaccination of gay men is occurring in the United States, Canada, Europe, and Australia, despite limited vaccine supply.

She added that, although monkeypox has been concentrated in communities of men who have sex with men, “anyone with multiple sexual partners should be vaccinated given the data.”

However, a WHO official recently cautioned that reports of breakthrough infections in individuals who were vaccinated against monkeypox constitute a reminder that “vaccine is not a silver bullet.”
 

Non-vaccine interventions are also needed

Other experts stressed the need for nonvaccine interventions.

In his editorial, Dr. Isaacs said an “expanded” ring vaccination strategy in communities of high risk is likely needed, but ultimately the outbreak will only be controlled if vaccination is accompanied by other measures such as identifying and isolating cases, making treatment available, and educating individuals about how to reduce their risk.

Aileen Marty, MD, a professor of infectious diseases at Florida International University, Miami, said in an interview that the new evidence makes it “incredibly important” to inform people that they might be infected by a sex partner even if that person does not have telltale lesions.

Dr. Marty said she has been advising men who have sex with men to “reduce or eliminate situations in which they find themselves with multiple anonymous individuals.”

Although most individuals recover from monkeypox, the disease can lead to hospitalization, disfigurement, blindness, and even death, Dr. Marty noted, adding that monkeypox is “absolutely a disease to avoid.”

Authors of the French study reported financial relationships with Gilead Sciences, Viiv Healthcare, MSD, AstraZeneca, Theratechnologies, Janssen Pharmaceuticals, Pfizer, GlaxoSmithKline, and bioMérieux. Dr. Isaacs reported grants from the Department of Veterans Affairs and the National Institutes of Health and royalties from UpToDate. Dr. Gandhi and Dr. Marty reported no relevant financial interests.

PORTLAND, ORE. – When patients present to Brandon L. Adler, MD, with dermatitis on the eyelid, face, or neck, he routinely asks them if they apply essential oils on their skin, or if they have an essential oil diffuser or nebulizer in their home.

“The answer is frequently ‘yes,’ ” Dr. Adler, clinical assistant professor of dermatology at the University of Southern California, Los Angeles, said at the annual meeting of the Pacific Dermatologic Association. “Essential oils are widely used throughout the wellness industry. They are contained in personal care products, beauty products, natural cleaning products, and they’re being diffused by our patients into the air. More than 75 essential oils are reported to cause allergic contact dermatitis.”

Natural chemical components contained in essential oils can cause skin reactions, especially linalool and limonene. “Linalool is most classically associated with lavender, while limonene is associated with citrus, but they’re found in many different plants,” said Dr. Adler, who directs USC’s contact dermatitis clinic. “On their own, linalool and limonene are not particularly allergenic; they’re not a big deal in the patch test clinic. The problem comes when we add air to the mix, because they oxidize to hydroperoxides of linalool and limonene. These are quite potent allergens.”

According to the most recent North American Contact Dermatitis Group data, 8.9% of patients undergoing patch testing tested positive to linalool hydroperoxides and 2.6% were positive to limonene hydroperoxides.

Dr. Adler discussed the case of a female massage therapist who presented with refractory hand dermatitis and was on methotrexate and dupilumab at the time of consultation but was still symptomatic. She patch-tested positive to limonene and linalool hydroperoxides as well as multiple essential oils that she had been using with her clients, ranging from sacred frankincense oil to basil oil, and she was advised to massage using only coconut or vegetable oils.

Essential oil allergy may also be related to cannabis allergy. According to Dr. Adler, allergic contact dermatitis to cannabis has been rarely reported, but in an analysis of 103 commercial topical cannabinoid preparations that he published with Vincent DeLeo, MD, also with USC, 84% contained a NACDG allergen, frequently essential oils.

More recently, Dr. Adler and colleagues reported the case of a 40-year-old woman who was referred for patch testing for nummular dermatitis that wasn’t responding to treatment. The patient was found to be using topical cannabis and also grew cannabis at home. “She asked to be patch-tested to her homegrown cannabis and had a strong positive patch test to the cannabis, linalool and limonene hydroperoxides, and other essential oils,” Dr. Adler recalled. “We sent her cannabis sample for analysis at a commercial lab and found that it contained limonene and other allergenic terpene chemicals.

“We’re just starting to unravel what this means in terms of our patients and how to manage them, but many are using topical cannabis and topical CBD. I suspect this is a lot less rare than we realize.”

Another recent case from Europe reported allergic contact dermatitis to Cannabis sativa (hemp) seed oil following topical application, with positive patch testing.

Dr. Adler disclosed that he has received research grants from the American Contact Dermatitis Society. He is also an investigator for AbbVie and a consultant for the Skin Research Institute.

She patch-tested positive to limonene and linalool hydroperoxides as well as multiple essential oils that she had been using with her clients, ranging from sacred frankincense oil to basil oil, and she was advised to massage using only coconut or vegetable oils.

Essential oil allergy may also be related to cannabis allergy. According to Dr. Adler, allergic contact dermatitis to cannabis has been rarely reported, but in an analysis of 103 commercial topical cannabinoid preparations that he published with Vincent DeLeo, MD, also with USC, 84% contained a NACDG allergen, frequently essential oils.

More recently, Dr. Adler and colleagues reported the case of a 40-year-old woman who was referred for patch testing for nummular dermatitis that wasn’t responding to treatment. The patient was found to be using topical cannabis and also grew cannabis at home. “She asked to be patch-tested to her homegrown cannabis and had a strong positive patch test to the cannabis, linalool and limonene hydroperoxides, and other essential oils,” Dr. Adler recalled. “We sent her cannabis sample for analysis at a commercial lab and found that it contained limonene and other allergenic terpene chemicals.

“We’re just starting to unravel what this means in terms of our patients and how to manage them, but many are using topical cannabis and topical CBD. I suspect this is a lot less rare than we realize.”

Another recent case from Europe reported allergic contact dermatitis to Cannabis sativa (hemp) seed oil following topical application, with positive patch testing.

Dr. Adler disclosed that he has received research grants from the American Contact Dermatitis Society. He is also an investigator for AbbVie and a consultant for the Skin Research Institute.

PORTLAND, ORE. – When patients present to Brandon L. Adler, MD, with dermatitis on the eyelid, face, or neck, he routinely asks them if they apply essential oils on their skin, or if they have an essential oil diffuser or nebulizer in their home.

“The answer is frequently ‘yes,’ ” Dr. Adler, clinical assistant professor of dermatology at the University of Southern California, Los Angeles, said at the annual meeting of the Pacific Dermatologic Association. “Essential oils are widely used throughout the wellness industry. They are contained in personal care products, beauty products, natural cleaning products, and they’re being diffused by our patients into the air. More than 75 essential oils are reported to cause allergic contact dermatitis.”

Natural chemical components contained in essential oils can cause skin reactions, especially linalool and limonene. “Linalool is most classically associated with lavender, while limonene is associated with citrus, but they’re found in many different plants,” said Dr. Adler, who directs USC’s contact dermatitis clinic. “On their own, linalool and limonene are not particularly allergenic; they’re not a big deal in the patch test clinic. The problem comes when we add air to the mix, because they oxidize to hydroperoxides of linalool and limonene. These are quite potent allergens.”

According to the most recent North American Contact Dermatitis Group data, 8.9% of patients undergoing patch testing tested positive to linalool hydroperoxides and 2.6% were positive to limonene hydroperoxides.

Dr. Adler discussed the case of a female massage therapist who presented with refractory hand dermatitis and was on methotrexate and dupilumab at the time of consultation but was still symptomatic.

People exposed to high levels of perfluorooctane sulfonic acid (PFOS) – a widely used synthetic chemical – run an increased risk of hepatocellular carcinoma, researchers say.

The correlation does not prove that PFOS causes this cancer, and more research is needed, but in the meantime, people should limit their exposure to it and others in its class, said Jesse Goodrich, PhD, a postdoctoral scholar in environmental medicine at the University of Southern California, Los Angeles.

“If you’re at risk for liver cancer because you have other risk factors, then these chemicals have the potential to kind of send you over the edge,” he told this news organization.

Dr. Goodrich and colleagues published their research online in JHEP Reports.

Dubbed “forever chemicals” because they can take thousands of years to break down, polyfluoroalkyl substances (PFAS) figure in makeup, food packaging, waterproof clothing, nonstick cookware, firefighting foams, and groundwater. They have spread through the atmosphere into rain and can be found in the blood of most Americans. PFOS is one of the most widely used PFAS.

“You can’t really escape them,” Dr. Goodrich said.

Previous research has linked PFAS to infertility, pregnancy complications, learning and behavioral problems in children, immune system issues, and higher cholesterol, as well as other cancers. Some experiments in animals suggested PFAS could cause liver cancer, and others showed a correlation between PFAS serum levels and biomarkers associated with liver cancer. But many of these health effects take a long time to develop.

“It wasn’t until we started to get really highly exposed groups of people that we started, as scientists, to be able to figure out what was going on,” said Dr. Goodrich.
 

High exposure, increased incidence

To measure the relationship between PFAS exposure and the incidence of hepatocellular carcinoma more definitively, Dr. Goodrich and colleagues analyzed data from the Multiethnic Cohort Study, a cohort of more than 200,000 people of African, Latin, Native Hawaiian, Japanese, and European ancestry tracked since the early 1990s in California and Hawaii. About 67,000 participants provided blood samples from 2001 to 2007.

From this cohort, the researchers found 50 people who later developed hepatocellular carcinoma. The researchers matched these patients with 50 controls of similar age at blood collection, sex, race, ethnicity, and study area who did not develop the cancer.

They found that people with more than 54.9 mcg/L of PFOS in their blood before any diagnosis of hepatocellular carcinoma were almost five times more likely to get the cancer (odds ratio 4.5; 95% confidence interval, 1.2-16.0), which was statistically significant (P = .02).

This level of PFOS corresponds to the 90th percentile found in the U.S. National Health and Nutrition Examination Survey (NHANES).

To get some idea of the mechanism by which PFOS might do its damage, the researchers also looked for linkage to levels of metabolites.

They found an overlap among high PFOS levels, hepatocellular carcinoma, and high levels of glucose, butyric acid (a short chain fatty acid), alpha-Ketoisovaleric acid (alpha branched-chain alpha-keto acid), and 7alpha-Hydroxy-3-oxo-4-cholestenoate (a bile acid). These metabolites have been associated in previous studies with metabolic disorders and liver disease.

Similarly, the researchers identified an association among the cancer, PFOS, and alterations in amino acid and glycan biosynthesis pathways.
 

Risk mitigation

The half-life of PFAS in the human body is about 3-7 years, said Dr. Goodrich.

“There’s not much you can do once they’re in there,” he said. “So, the focus needs to be on preventing the exposure in the first place.”

People can limit exposure by avoiding water contaminated with PFAS or filtering it out, Dr. Goodrich said. He recommended avoiding fish from contaminated waterways and nonstick cookware. The Environmental Protection Agency has more detailed recommendations.

But giving patients individualized recommendations is difficult, said Vincent Chen, MD, MS, a clinical instructor in gastroenterology at the University of Michigan, Ann Arbor, who was not involved in the study. Most clinicians don’t know their patients’ PFOS levels.

“It’s not that easy to get a test,” Dr. Chen told this news organization.

People can also mitigate their risk factors for hepatocellular carcinoma, such as a poor diet, a lack of exercise, and smoking, said Dr. Goodrich.

The researchers found that patients with hepatocellular carcinoma were more likely to be overweight and have diabetes, and PFOS was associated with higher fasting glucose levels. This raises the possibility that PFOS increases the risk for hepatocellular carcinoma by causing diabetes and obesity.

Dr. Goodrich and his colleagues tried to address this question by adjusting for baseline body mass index (BMI) and diabetes diagnosis in their statistical analysis.

After adjusting for BMI, they found that the association between PFOS and hepatocellular carcinoma diminished to a threefold risk (OR, 2.90; 95% CI, 0.78-10.00) and was no longer statistically significant (P = .11).

On the other hand, adjusting for diabetes did not change the significance of the relationship between PFOS and the cancer (OR, 5.7; 95% CI, 1.10-30.00; P = .04).

The sample size was probably too small to adequately tease out this relationship, Dr. Chen said. Still, he said, “I thought it was a very, very important study.”

The levels of PFOS found in the blood of Americans has been declining since the 1999-2000 NHANES, Dr. Chen pointed out. But that’s not as reassuring as it sounds.

“The problem is that if you put a regulation limiting the use of one PFAS, what people can do is just substitute with another PFAS or another molecule, which for all we know could be equally harmful,” Dr. Chen said.

Funding was provided by the Southern California Environmental Health Science Center supported by the National Institutes of Health. Dr. Goodrich and Dr. Chen report no relevant financial relationships.

SACRAMENTO – California is trying to ease the pain of vasectomies by making them free for millions of residents.

Federal law and state law require most health insurers to cover prescription contraceptives at no cost to the patient. But those provisions apply to only 18 Food and Drug Administration–approved birth control options for women, so anyone with testicles is out of luck.

California lawmakers are now considering a bill that would expand that requirement to male sterilization and non-prescription birth control, including condoms and contraceptive sponges. If the Contraceptive Equity Act of 2022 passes, commercial insurance plans regulated by the state won’t be allowed to impose out-of-pocket costs, like copays, coinsurance, and deductibles, on those modes of birth control.

“It’s pretty groundbreaking in that way – it’s a whole new framework to think about contraception as something that is relevant for people of all genders,” said Liz McCaman Taylor, a senior attorney with the National Health Law Program, a group that advocates for the health rights of low-income people.

A vasectomy is an outpatient surgical procedure in which the patient’s supply of sperm is cut off from his semen by sealing or snipping the tubes that transport sperm from the testes to the penis. Most men need to recover on the couch with an ice pack for a day or 2, and a test a few months later determines whether the procedure worked.

Because vasectomies are elective procedures and usually not urgent, price can be a deciding factor.

For Nathan Songne, cost was the most stressful part of the procedure. For several years, the 31-year-old had known he didn’t want to have kids biologically. Better to adopt a 4-year-old and skip the diaper stage, he thought. He was adopted by his stepfather as a child and knew he didn’t need to be genetically related to his children to love them.

“My only concern was that I had no idea how much it was going to cost me because nobody told me,” said Mr. Songne, who lives in Mission Viejo, in Orange County. If the procedure cost $1,000, as he expected, he wouldn’t be able to afford it.

Mr. Songne’s insurance, which he gets through his work assembling guitars, covered 70% of the Aug. 8 procedure, leaving him with a bill of just under $200. “Cost did affect my decision, but because it was only $200, it made me feel a lot more relieved about continuing on with the vasectomy.”

There are two hot times of year in the vasectomy business, according to Mary Samplaski, MD, an associate professor of urology at the University of Southern California, Los Angeles. First, she sees an uptick during the March Madness college basketball tournament, when men choose to recover on the couch watching hoops.

The end of the year is also busy, she said, because many patients have finally met their annual insurance deductible and can afford the procedure.

Patients discuss out-of-pocket costs in about 20% of her vasectomy consultations. “It’s obviously a nerve-wracking procedure,” Dr. Samplaski said. “And on top of that, if your copay is high, there’s even less reason to want to do it.”

In April, Jacob Elert comparison-shopped for a vasectomy near his home in Sacramento because his health plan doesn’t cover the procedure. He had hoped to schedule one with his regular urologist, but that would have come with a $1,500 price tag.

Instead, he found a chain of vasectomy clinics where he could get the procedure for $850. Three months later, a test confirmed the vasectomy was a success.

Mr. Elert has no regrets, but had price not been a factor, he would have preferred to go to his regular urologist. “That’s the doctor I trust,” Mr. Elert said. “But it was just way too expensive.”

In November, California voters will decide whether to lock rights to abortion and contraception into the state constitution. But Proposition 1 doesn’t address issues such as cost and coverage, said Amy Moy, a spokesperson for Essential Access Health, a group that runs California’s Title X family planning program.

“The constitutional amendment is kind of the long-term protection, and we are still working to reduce barriers for Californians on the short-term and day-to-day level regardless of their gender,” she said.

SB 523 has sailed through preliminary votes in the state legislature, which faces an end-of-August deadline to act on bills. If the measure passes, it would take effect in 2024, and California would join a handful of states that require plans they regulate to completely cover vasectomies or nonprescription birth control.

The California Association of Health Plans is still evaluating the measure, which may be amended in the final days of the legislative session. But the association generally opposes bills that require additional insurance benefits because they could lead to higher premiums, spokesperson Mary Ellen Grant said.

SB 523 applies to more than 14 million Californians who work for the state, have a student health plan through a university, or have state-regulated commercial health plans. They would become eligible to receive free over-the-counter birth control – such as emergency contraception, condoms, spermicide, and contraceptive sponges – in addition to vasectomies. The bill would not apply to the millions of Californians whose health insurance plans are regulated by the federal government.

The specifics of how the benefit would work, including the frequency and amount of birth control that insurers must cover and whether patients would have to pay upfront and be reimbursed later, would be hammered out after the measure is adopted. Ms. McCaman Taylor said allowing people to simply present their insurance card at a pharmacy counter and walk away with the birth control they need would be preferable.

“We kind of learned from the national experiment with COVID over-the-counter tests that reimbursement wasn’t the best model,” she said. “If people can’t afford to pay out of pocket for it, they’re just not going to get it.”

The California Health Benefits Review Program, which analyzes legislation, projected that roughly 14,200 people with state-regulated commercial insurance would get vasectomies in California in 2022. Eliminating cost sharing would increase the number of vasectomies by 252 in the law’s first year, the program estimated.

It’s a small increase. But that, plus a jump in the use of other contraceptives covered by the bill, particularly condoms, could add up to a big reduction in unintended pregnancies. Roughly 12,300 unplanned pregnancies might be averted each year if the mandate takes effect, a reduction of more than 11%, according to the analysis.

The California Association of Health Plans is still evaluating the measure, which may be amended in the final days of the legislative session. But the association generally opposes bills that require additional insurance benefits because they could lead to higher premiums, spokesperson Mary Ellen Grant said.

SB 523 applies to more than 14 million Californians who work for the state, have a student health plan through a university, or have state-regulated commercial health plans. They would become eligible to receive free over-the-counter birth control – such as emergency contraception, condoms, spermicide, and contraceptive sponges – in addition to vasectomies. The bill would not apply to the millions of Californians whose health insurance plans are regulated by the federal government.

The specifics of how the benefit would work, including the frequency and amount of birth control that insurers must cover and whether patients would have to pay upfront and be reimbursed later, would be hammered out after the measure is adopted. Ms. McCaman Taylor said allowing people to simply present their insurance card at a pharmacy counter and walk away with the birth control they need would be preferable.

“We kind of learned from the national experiment with COVID over-the-counter tests that reimbursement wasn’t the best model,” she said. “If people can’t afford to pay out of pocket for it, they’re just not going to get it.”

The California Health Benefits Review Program, which analyzes legislation, projected that roughly 14,200 people with state-regulated commercial insurance would get vasectomies in California in 2022. Eliminating cost sharing would increase the number of vasectomies by 252 in the law’s first year, the program estimated.

It’s a small increase. But that, plus a jump in the use of other contraceptives covered by the bill, particularly condoms, could add up to a big reduction in unintended pregnancies. Roughly 12,300 unplanned pregnancies might be averted each year if the mandate takes effect, a reduction of more than 11%, according to the analysis.

SACRAMENTO – California is trying to ease the pain of vasectomies by making them free for millions of residents.

Federal law and state law require most health insurers to cover prescription contraceptives at no cost to the patient. But those provisions apply to only 18 Food and Drug Administration–approved birth control options for women, so anyone with testicles is out of luck.

California lawmakers are now considering a bill that would expand that requirement to male sterilization and non-prescription birth control, including condoms and contraceptive sponges. If the Contraceptive Equity Act of 2022 passes, commercial insurance plans regulated by the state won’t be allowed to impose out-of-pocket costs, like copays, coinsurance, and deductibles, on those modes of birth control.

“It’s pretty groundbreaking in that way – it’s a whole new framework to think about contraception as something that is relevant for people of all genders,” said Liz McCaman Taylor, a senior attorney with the National Health Law Program, a group that advocates for the health rights of low-income people.

A vasectomy is an outpatient surgical procedure in which the patient’s supply of sperm is cut off from his semen by sealing or snipping the tubes that transport sperm from the testes to the penis. Most men need to recover on the couch with an ice pack for a day or 2, and a test a few months later determines whether the procedure worked.

Because vasectomies are elective procedures and usually not urgent, price can be a deciding factor.

For Nathan Songne, cost was the most stressful part of the procedure. For several years, the 31-year-old had known he didn’t want to have kids biologically. Better to adopt a 4-year-old and skip the diaper stage, he thought. He was adopted by his stepfather as a child and knew he didn’t need to be genetically related to his children to love them.

“My only concern was that I had no idea how much it was going to cost me because nobody told me,” said Mr. Songne, who lives in Mission Viejo, in Orange County. If the procedure cost $1,000, as he expected, he wouldn’t be able to afford it.

Mr. Songne’s insurance, which he gets through his work assembling guitars, covered 70% of the Aug. 8 procedure, leaving him with a bill of just under $200. “Cost did affect my decision, but because it was only $200, it made me feel a lot more relieved about continuing on with the vasectomy.”

There are two hot times of year in the vasectomy business, according to Mary Samplaski, MD, an associate professor of urology at the University of Southern California, Los Angeles. First, she sees an uptick during the March Madness college basketball tournament, when men choose to recover on the couch watching hoops.

The end of the year is also busy, she said, because many patients have finally met their annual insurance deductible and can afford the procedure.

Patients discuss out-of-pocket costs in about 20% of her vasectomy consultations. “It’s obviously a nerve-wracking procedure,” Dr. Samplaski said. “And on top of that, if your copay is high, there’s even less reason to want to do it.”

In April, Jacob Elert comparison-shopped for a vasectomy near his home in Sacramento because his health plan doesn’t cover the procedure. He had hoped to schedule one with his regular urologist, but that would have come with a $1,500 price tag.

Instead, he found a chain of vasectomy clinics where he could get the procedure for $850. Three months later, a test confirmed the vasectomy was a success.

Mr. Elert has no regrets, but had price not been a factor, he would have preferred to go to his regular urologist. “That’s the doctor I trust,” Mr. Elert said. “But it was just way too expensive.”

In November, California voters will decide whether to lock rights to abortion and contraception into the state constitution. But Proposition 1 doesn’t address issues such as cost and coverage, said Amy Moy, a spokesperson for Essential Access Health, a group that runs California’s Title X family planning program.

“The constitutional amendment is kind of the long-term protection, and we are still working to reduce barriers for Californians on the short-term and day-to-day level regardless of their gender,” she said.

If the measure passes, it would take effect in 2024, and California would join a handful of states that require plans they regulate to completely cover vasectomies or nonprescription birth control.

A 5-minute bout of direct-to-consumer advertising (DTCA) for prescription heart drugs was associated with favorable perceptions of both medication use and pharmaceutical companies, but did not seem to negate intentions to use lifestyle interventions, a survey study shows.

Participants who watched ads for various prescription heart drugs, with or without price disclosure, were more likely to report positive perceptions of drug companies and intentions to take actions such as switching medications.

The ads did not seem to affect intentions to eat healthfully and exercise.

The study was published online in JAMA Health Forum.
 

DTCA ‘unlikely to have an adverse effect’

“Increasing prevalence of DTCA may promote an overreliance on medication over healthy lifestyle choices to manage chronic conditions,” coauthor Yashaswini Singh, MPA, a PhD candidate at the Johns Hopkins University, Baltimore, told this news organization. “Thus, we hypothesized that DTCA exposure would reduce the likelihood of individuals engaging in preventive health behaviors.”

“However,” she said, “our results did not support this hypothesis, suggesting that exposure to DTCA for heart disease medication is unlikely to have an adverse effect on individuals’ intentions to engage in diet and exercise.”

That said, she added, “DTCA of prescription drugs can contribute to rising drug costs due to overprescribing of both inappropriate and brand-name drugs over cheaper generic alternatives. While we do not examine this mechanism in our paper, this remains an important question for future research.”

For the study, the team recruited 2,874 individuals (mean age, 53.8 years; 54% men; 83% White) from a U.S. nationally representative sample of people at high risk of cardiovascular disease, the Ipsos Public Affairs KnowledgePanel.

Participants were randomly assigned to one of three interventions: DTCA for heart disease medications, DTCA for heart disease medications with price disclosure, or nonpharmaceutical advertising (control). Each group watched five 1-minute videos for a total of 5 minutes of advertising exposure.

One group viewed ads for four heart disease medications – two ads for sacubitril/valsartan (Entresto, Novartis) and one each for rivaroxaban (Xarelto, Bayer), evolocumab (Repatha, Amgen), and ticagrelor (Brilinta, AstraZeneca); the second group saw the same ads, but with prices spliced in; and controls watched videos for nondrug products, such as consumer electronics.

Participants then completed a questionnaire to measure medication- and lifestyle-related intentions, as well as health-related beliefs and perceptions. Using a scale of 1 (highly unlikely) to 5 (highly likely), they rated the likelihood of their switching medication, asking a physician or insurer about a medication, searching for the drug online, or taking it as directed. The same scale was used to rate the likelihood of their being more physically active or eating more healthfully.

On a scale of 1 (always disagree) to 5 (always agree), they also related their perceptions of pharmaceutical manufacturers as being competent, innovative, and trustworthy.

To measure the magnitude of DTCA associations, the researchers calculated marginal effects (MEs) of treatment – that is, the difference in probability of an outcome between the treatment and control arms.

They found a positive association between DTCA and medication-related behavioral intentions, including intention to switch medication (ME, 0.004; P = .002) and engage in information-seeking behaviors (ME, 0.02; P = .01).

There was no evidence suggesting that pharmaceutical DTCA discouraged use of nonpharmacologic lifestyle interventions to help manage heart disease. DTCA also was positively associated with consumers’ favorable perceptions of pharmaceutical manufacturers (competence: ME, 0.03; P = .01; innovative: ME, 0.03; P = .008).

No differential associations were seen for price disclosures in DTCA.
 

Questions remain

The authors acknowledged that the study focused on short-term behavioral intentions and that “future research should focus on the long-term effects of advertising in a real-world randomized setting.”

Ms. Singh said additional questions, some of which her team is investigating, include “understanding the interaction between government policies [such as] drug pricing reforms and firms’ advertising decisions; understanding whether observed changes in individuals’ health beliefs translate into actual changes to information-seeking behavior and health care utilization; and whether the demographic, political, and social characteristics of individuals shape their behavioral responses to advertising.”

Johanna Contreras, MD, an advanced heart failure and transplantation cardiologist at Mount Sinai Hospital, New York, said in an interview that the findings don’t surprise her. “The caveat is that this study was an online survey, so it only captured the beliefs and intentions, but not patient demand for the product and use of the product.”

“I do believe DTCA can create positive intentions towards the product ... and could make people more receptive to interventions,” she said. However, the information must be presented in a balanced way.

In addition, she noted, “price is still important. I think people take pricing into account when deciding to proceed with an intervention. If the price is ‘right’ or a little lower than expected, then they will likely consider the product. But if the price is significantly lower, then they may not trust that it is a good product. Generic drugs are an example. Even though they are approved and far cheaper than brand names, patients are often skeptical to take them.”

The study was funded with a grant from the Blue Cross Blue Shield of Illinois Affordability Cures Consortium. Ms. Singh and coauthors disclosed no relevant financial relationships.

New research discounts the long-held notion that aspartame and other nonnutritive sweeteners (NNS) have no effect on the human body.

Researchers found that these sugar substitutes are not metabolically inert and can alter the gut microbiome in a way that can influence blood glucose levels.

The study was published online in the journal Cell.


 

Gut reaction?

Several years ago, a team led by Eran Elinav, MD, PhD, an immunologist and microbiome researcher at the Weizmann Institute of Science, Rehovot, Israel, observed that these sweeteners affect the microbiome of mice in ways that could affect glycemic responses.

They have now confirmed this observation in a randomized controlled trial with 120 healthy adults.

Weighing the evidence

Several experts weighed in on the results in a statement from the U.K. nonprofit organization, Science Media Centre.

Duane Mellor, PhD, RD, RNutr, registered dietitian and senior teaching fellow, Aston University, Birmingham, England, notes that the study does not show a link between all NNS and higher blood glucose levels in the long term (only after a glucose tolerance test).

“It did suggest, though, that some individuals who do not normally consume sweeteners may not tolerate glucose as well after consuming six sachets of either saccharin or sucralose mixed with glucose per day,” Dr. Mellor says.

Kim Barrett, PhD, distinguished professor of physiology and membrane biology, University of California, Davis, concurs, saying “this well-designed study indicates the potential for NNS to have adverse effects in at least some individuals.”

The study also does not provide any information about how people who normally consume sweeteners or people with either type 1 or type 2 diabetes respond to NNS.

“Therefore, for some people, it is likely to be a better option and more sustainable approach to use sweeteners as a ‘stepping stone’ allowing them to reduce the amount of added sugar in foods and drinks, to reduce their sugar intake and still enjoy what they eat and drink, on the way to reducing both added sugar and sweeteners in their diet,” Dr. Mellor suggests.

Kevin McConway, PhD, with the Open University, Milton Keynes, England, said it’s “important to understand that the research is not saying that these sweeteners are worse for us, in heath terms, than sugar.

“But exactly what the health consequences of all this, if any, might be is a subject for future research,” Dr. McConway added.

Kathy Redfern, PhD, lecturer in human nutrition, University of Plymouth (England) agrees.

“We still have a lot to learn about the human microbiome, and although this study suggests two of the sweeteners tested in this study (sucralose and saccharin) significantly affected glucose tolerance, these deviations were small,” she says.

The International Sweeteners Association also weighs in, saying, “No conclusions about the effects of low/no calorie sweeteners on glucose control or overall health can be extrapolated from this study for the general population or for people who typically consume sweeteners, including people living with diabetes.”

They add “a recent review of the literature concluded that there is clear evidence that changes in the diet unrelated to low/no calorie sweeteners consumption are likely the major determinants of change in gut microbiota.”

Nevertheless, Dr. Redfern says the results “warrant further investigation to assess how small changes in glucose tolerance in response to NNS consumption may influence longer-term glucose tolerance and risk for metabolic complications, such as type 2 diabetes.”

The study had no specific funding. Dr. Elinav is a scientific founder of DayTwo and BiomX, a paid consultant to Hello Inside and Aposense, and a member of the scientific advisory board of Cell. Dr. Mellor has provided consultancy to the International Sweetener Agency and has worked on projects funded by the Food Standards Agency that investigated the health effects of aspartame. Dr. Barrett, Dr. McConway, and Dr. Redfern report no relevant financial relationships.

The study also does not provide any information about how people who normally consume sweeteners or people with either type 1 or type 2 diabetes respond to NNS.

“Therefore, for some people, it is likely to be a better option and more sustainable approach to use sweeteners as a ‘stepping stone’ allowing them to reduce the amount of added sugar in foods and drinks, to reduce their sugar intake and still enjoy what they eat and drink, on the way to reducing both added sugar and sweeteners in their diet,” Dr. Mellor suggests.

Kevin McConway, PhD, with the Open University, Milton Keynes, England, said it’s “important to understand that the research is not saying that these sweeteners are worse for us, in heath terms, than sugar.

“But exactly what the health consequences of all this, if any, might be is a subject for future research,” Dr. McConway added.

Kathy Redfern, PhD, lecturer in human nutrition, University of Plymouth (England) agrees.

“We still have a lot to learn about the human microbiome, and although this study suggests two of the sweeteners tested in this study (sucralose and saccharin) significantly affected glucose tolerance, these deviations were small,” she says.

The International Sweeteners Association also weighs in, saying, “No conclusions about the effects of low/no calorie sweeteners on glucose control or overall health can be extrapolated from this study for the general population or for people who typically consume sweeteners, including people living with diabetes.”

They add “a recent review of the literature concluded that there is clear evidence that changes in the diet unrelated to low/no calorie sweeteners consumption are likely the major determinants of change in gut microbiota.”

Nevertheless, Dr. Redfern says the results “warrant further investigation to assess how small changes in glucose tolerance in response to NNS consumption may influence longer-term glucose tolerance and risk for metabolic complications, such as type 2 diabetes.”

The study had no specific funding. Dr. Elinav is a scientific founder of DayTwo and BiomX, a paid consultant to Hello Inside and Aposense, and a member of the scientific advisory board of Cell. Dr. Mellor has provided consultancy to the International Sweetener Agency and has worked on projects funded by the Food Standards Agency that investigated the health effects of aspartame. Dr. Barrett, Dr. McConway, and Dr. Redfern report no relevant financial relationships.
