WASHINGTON – Results from new analyses further fleshed out the potent effect by the investigational SGLT1&2 inhibitor sotagliflozin on major cardiovascular adverse events in patients with type 2 diabetes, chronic kidney disease, and at high risk for cardiovascular disease in the SCORED trial that randomized more than 10,000 patients.

In prespecified, secondary analyses of the SCORED results, treatment with sotagliflozin during a median of 16 months was linked to a significant 21% risk reduction relative to placebo for the combined incidence of total major adverse cardiovascular events (MACE), which included cardiovascular death, first and recurrent episodes of nonfatal MI, and nonfatal stroke among the 5,144 randomized patients who entered the trial with a history of cardiovascular disease (CVD), Deepak L. Bhatt, MD, said at the annual scientific sessions of the American College of Cardiology.

Among the 5,440 patients in the study who did not have a history of CVD (although they did have at least one major risk factor or at least two minor risk factors), treatment with sotagliflozin was linked to a significant 26% relative risk reduction in total MACE events.

Part of these overall MACE benefits resulted from similar improvements from sotagliflozin treatment on the individual outcomes of total nonfatal MI and total nonfatal strokes. Treatment with sotagliflozin cut these MIs by a significant 31% in patients with a history of CVD relative to patients who received placebo, and by a relative 34% in those without a CVD event in their history, a difference compared with placebo that fell short of significance, said Dr. Bhatt, professor of medicine at Harvard Medical School and executive director of interventional cardiovascular programs at Brigham and Women’s Health, both in Boston.

Treatment with sotagliflozin also cut total nonfatal strokes by 31% relative to placebo in patients with a history of CVD, and by a relative 38% in those without a CVD history. Both differences fell short of significance.
 

An early MACE benefit and a stroke benefit

“This stroke benefit has not been clearly seen” with any agent from the closely related sodium-glucose cotransport-2 (SGLT2) inhibitor class, and “the MACE benefit appeared very early,” within 3 months from the start of sotagliflozin treatment, “which may be because of the SGLT1 inhibition,” Dr. Bhatt said during his report.

The SGLT1 receptor is the primary mechanism cells in the gut use to absorb glucose and galactose in the human gastrointestinal tract, Dr. Bhatt explained, while the SGLT2 receptor appears on kidney cells and is the major player in the reabsorption of filtered glucose. The SGLT2 inhibitor class includes the agents canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), while sotagliflozin inhibits both SGLT1 and SGLT2.

Main results from SCORED appeared in a report first released in late 2020, and showed that for the study’s primary endpoint treatment with sotagliflozin linked with a significant 26% relative risk reduction for the composite of cardiovascular deaths, hospitalizations for heart failure, and urgent visits for heart failure (N Engl J Med. 2021 Jan 14;384[2]:129-39). Patient follow-up in SCORED was not as long as originally planned when the study stopped early due to a loss of funding from a sponsor that was triggered by the COVID-19 pandemic.

MACE results ‘heterogeneous’ from SGLT2 inhibitors

Sotagliflozin and agents from the SGLT2 inhibitor class “have been consistent” in their benefits for reducing cardiovascular death and hospitalization for heart failure, but for MACE, the results from the SGLT2 inhibitors “have been more heterogeneous,” and the effect of sotagliflozin on MACE “were different in SCORED,” commented Michelle L. O’Donoghue, MD, MPH, a cardiologist at Brigham and Women’s Hospital in Boston who was not involved with this work.

“The results suggest a benefit [from sotagliflozin] on atherosclerotic events, which could be a potential advantage” compared with the SGLT2 inhibitors, “but the heterogeneity of this effect” among these agents means that more confirmatory data are needed for sotagliflozin, Dr. O’Donoghue said in an interview.

“There is a lot of enthusiasm for the concept” of combined inhibition of the SGLT1 and 2 receptors, and if more evidence for unique benefits of this effect accumulate “it may lead to increased enthusiasm for sotagliflozin,” she said. “A lot will also depend on pricing decisions” for sotagliflozin, if it receives U.S. marketing approval from the Food and Drug Administration. Decisions about which agent from the SGLT2 inhibitor class to prescribe “are often being made based on price right now,” Dr. O’Donoghue said.

Lexicon Pharmaceuticals, the company developing sotagliflozin, has announced plans to resubmit its new drug application for sotagliflozin to the FDA later in 2022, with the agency’s approval decision likely occurring late in 2022 or sometime during 2023. In February, the company withdrew its December 2021 application to correct a “technical issue” it had found.

An additional analysis reported by Dr. Bhatt used combined data from SCORED as well as several additional randomized trials of sotagliflozin involving a total of more than 20,000 patients that showed a significant 21% reduction in the incidence of MACE compared with placebo.

During his talk, Dr. Bhatt said that sotagliflozin was potentially superior to the agents that inhibit only SGLT2. In an interview, he based this tentative assessment on at least four attributes of sotagliflozin that have emerged from trial results:

• The drug’s ability to significantly reduce MACE and to have this effect apparent within a few months of treatment onset;
• The significantly reduced rate of stroke with sotagliflozin (when patients are not subdivided into those with or without a history of CVD) that has not yet been seen with any SGLT2 inhibitor;
• The ability of sotagliflozin to reduce hemoglobin A1c levels in patients with type 2 diabetes even when their estimated glomerular filtration rate is less than 30 mL/min per 1.73 m², an effect not seen with SGLT2 inhibitors and possibly explained by sotagliflozin having an effect on gut absorption of glucose in addition to its SGLT2 inhibitory effect in the kidney;
• And the proven ability of sotagliflozin to be safe and effective when initiated in patients hospitalized for heart failure, a property that so far has only also been shown for the SGLT2 inhibitor empagliflozin in the EMPULSE trial (Nature Med. 2022 Mar;28: 568-74).

SCORED was sponsored by Sanofi and Lexicon Pharmaceuticals, the companies originally developing sotagliflozin, although with the withdrawal of Sanofi’s support, further development is now sponsored entirely by Lexicon. Dr. Bhatt received research funding from Sanofi and Lexicon that was paid to Brigham and Women’s Health, and he has been an advisor to numerous companies. Dr. O’Donoghue has been a consultant to Amgen, Janssen, and Novartis, and has received research funding from Amgen, AZ MedImmune, Intarcia, Janssen, Merck, and Novartis.

Pregnant women with even mild hypertension should receive blood pressure–lowering medications to reduce the likelihood of adverse outcomes for the mother and the child, according to a large, open-label, randomized trial.

“Treating to the blood pressure goal in this study reduced the risk of adverse events associated with pregnancy but did not impair fetal growth,” Alan T. Tita, MD, PhD, associate dean for Global and Women’s Health, University of Alabama, Birmingham, reported at the annual scientific sessions of the American College of Cardiology.

The question of whether to treat chronic hypertension during pregnancy has been “an international controversy for decades,” said Dr. Tita, who led the investigator-initiated Chronic Hypertension and Pregnancy (CHAP) trial.

For the composite primary outcome of severe preeclampsia, medically indicated preterm birth at less than 35 weeks of gestation, placental abruption, or fetal/neonatal death, the treatment of hypertension versus no treatment showed a relative risk reduction of 18% (30.2% vs. 37%, (hazard ratio, 0.82; P < .001).
 

Small for gestational age is primary safety endpoint

An increase in preeclampsia risk in women whose fetus was small for gestational age (SGA), a theoretical consequence of reductions in arterial pressure, was not seen. The rate of SGA, defined as below the 10^th percentile, was slightly higher in the treatment group (11.2% vs. 10.4%), but the difference did not approach significance (P = 0.76).

By answering this long-pending question, the CHAP data are “practice changing,” declared an ACC-invited commentator, Athena Poppas, MD, chief of cardiology and director of the Lifespan Cardiovascular Institute, Providence, R.I. She agreed that the need for treatment of mild chronic hypertension has been a dilemma for clinicians that is now acceptably resolved.

In this trial, 2,408 pregnant women with chronic mild hypertension defined as a blood pressure of 160/90 mm Hg were randomized to treatment with a goal blood pressure of less than 140/90 mm Hg or no treatment unless the blood pressure rose to at least 160/105. All women had singleton pregnancies. Enrollment before 23 weeks of gestation was required. Severe hypertension (at least 160/105 mm Hg) was an exclusion criterion, as were several comorbidities, such as kidney disease.
 

Combination therapy accepted for <140/90 mm Hg goal

The beta-blocker labetalol or the calcium channel blocker nifedipine as single agents were the preferred antihypertensive medications in the protocol, but other medications were permitted. To reach the blood pressure goal, the single-agent therapy was titrated to the maximum dose before starting a second agent.

After randomization the systolic and diastolic blood pressures fell in both groups, but they fell more and remained consistently lower in the active treatment group, particularly during the first 20 weeks after randomization, according to graphs displayed by Dr. Tita. Over the course of the study, the mean diastolic blood pressures were 129.5 and 132.6 mm Hg in the active treatment and control groups, respectively, while the systolic pressures were 79.1 vs. 81.5 mm Hg.

When the components of the primary outcome were evaluated separately, the greatest advantage of treatment was the reduction in the rate of severe eclampsia (23.3% vs. 29.1%; HR, 0.80: 95% confidence interval, 0.70-0.92) and preterm birth (12.2% vs. 16.7%; HR, 0.73: 95% CI, 0.60-0.89).

Across a large array of subgroups, including those with or without diabetes and those treated before or after 14 weeks of gestation, there was a consistent advantage for treatment, even if not statistically different. It is notable that 48% of patients were Black and 35% had a body mass index of at least 40. The active treatment was favored across all groups stratified by these characteristics.

Although the incidences of placental abruption (1.7% on treatment vs. 1.9% without) and fetal or neonatal death (3.5% vs. 4.3%) were lower in the active treatment group, they were uncommon events in both arms of the study. The differences did not reach statistical significance.
 

Maternal morbidity rates lower on treatment

Severe SGA, which was defined as below the 5^th percentile, was also numerically but not significantly higher in the control arm than in the group receiving treatment (5.1% vs. 5.5%), but the incidence of composite adverse maternal events was numerically lower (2.1% vs. 2.8%). The incidences of all components of maternal morbidity, such as maternal death (0.1% vs. 0.2%) pulmonary edema (0.4% vs. 0.9%), heart failure (0.1% vs. 0.1%), and acute kidney injury (0.8% vs. 1.2%), were either lower or the same on active treatment versus no treatment.

According to Dr. Tita, who called CHAP one of the largest and most diverse studies to address the value of treating mild hypertension in pregnancy, the American College of Obstetricians and Gynecologists (ACOG) is evaluating these data for changing their current guidelines for managing hypertension during pregnancy.

“The rate of chronic hypertension during pregnancy has been rising in the United States due to the increase in the average age of pregnant women and the rising rates of obesity,” Dr. Tita commented.

“We definitely needed these data,” said Mary Norine Walsh, MD, medical director, Ascension Saint Vincent Cardiovascular Research Institute, Indianapolis. Not only has the value of treating mild hypertension been unresolved, but Dr. Walsh pointed out that the rates of maternal mortality in the United States are rising and now generally exceed those of many other developed countries.

There are several features in the design of this trial that make the results even more salient to clinical practice, according to Dr. Walsh. This includes the fact that about half of patients enrolled were on Medicaid. As a result, the study confirmed benefit in what Dr. Walsh characterized as a “vulnerable” population.

“We will be busy now to make sure that our [pregnant] patients are achieving these target blood pressures,” Dr. Walsh said. She indicated that CHAP validates the treatment target of 140/90 mm Hg as a standard of care.

The results were published in the New England Journal of Medicine simultaneously with its ACC presentation.

The trial was funded by the National Heart, Lung, and Blood Institute. Dr. Tita reports research grants from Pfizer. Dr. Walsh reports a financial relationship with EBR Systems. Dr. Poppas reports no potential conflicts of interest.

Pregnant women with even mild hypertension should receive blood pressure–lowering medications to reduce the likelihood of adverse outcomes for the mother and the child, according to a large, open-label, randomized trial.

“Treating to the blood pressure goal in this study reduced the risk of adverse events associated with pregnancy but did not impair fetal growth,” Alan T. Tita, MD, PhD, associate dean for Global and Women’s Health, University of Alabama, Birmingham, reported at the annual scientific sessions of the American College of Cardiology.

The question of whether to treat chronic hypertension during pregnancy has been “an international controversy for decades,” said Dr. Tita, who led the investigator-initiated Chronic Hypertension and Pregnancy (CHAP) trial.

For the composite primary outcome of severe preeclampsia, medically indicated preterm birth at less than 35 weeks of gestation, placental abruption, or fetal/neonatal death, the treatment of hypertension versus no treatment showed a relative risk reduction of 18% (30.2% vs. 37%, (hazard ratio, 0.82; P < .001).
 

Small for gestational age is primary safety endpoint

An increase in preeclampsia risk in women whose fetus was small for gestational age (SGA), a theoretical consequence of reductions in arterial pressure, was not seen. The rate of SGA, defined as below the 10^th percentile, was slightly higher in the treatment group (11.2% vs. 10.4%), but the difference did not approach significance (P = 0.76).

By answering this long-pending question, the CHAP data are “practice changing,” declared an ACC-invited commentator, Athena Poppas, MD, chief of cardiology and director of the Lifespan Cardiovascular Institute, Providence, R.I. She agreed that the need for treatment of mild chronic hypertension has been a dilemma for clinicians that is now acceptably resolved.

In this trial, 2,408 pregnant women with chronic mild hypertension defined as a blood pressure of 160/90 mm Hg were randomized to treatment with a goal blood pressure of less than 140/90 mm Hg or no treatment unless the blood pressure rose to at least 160/105. All women had singleton pregnancies. Enrollment before 23 weeks of gestation was required. Severe hypertension (at least 160/105 mm Hg) was an exclusion criterion, as were several comorbidities, such as kidney disease.
 

Combination therapy accepted for <140/90 mm Hg goal

The beta-blocker labetalol or the calcium channel blocker nifedipine as single agents were the preferred antihypertensive medications in the protocol, but other medications were permitted. To reach the blood pressure goal, the single-agent therapy was titrated to the maximum dose before starting a second agent.

After randomization the systolic and diastolic blood pressures fell in both groups, but they fell more and remained consistently lower in the active treatment group, particularly during the first 20 weeks after randomization, according to graphs displayed by Dr. Tita. Over the course of the study, the mean diastolic blood pressures were 129.5 and 132.6 mm Hg in the active treatment and control groups, respectively, while the systolic pressures were 79.1 vs. 81.5 mm Hg.

When the components of the primary outcome were evaluated separately, the greatest advantage of treatment was the reduction in the rate of severe eclampsia (23.3% vs. 29.1%; HR, 0.80: 95% confidence interval, 0.70-0.92) and preterm birth (12.2% vs. 16.7%; HR, 0.73: 95% CI, 0.60-0.89).

Across a large array of subgroups, including those with or without diabetes and those treated before or after 14 weeks of gestation, there was a consistent advantage for treatment, even if not statistically different. It is notable that 48% of patients were Black and 35% had a body mass index of at least 40. The active treatment was favored across all groups stratified by these characteristics.

Although the incidences of placental abruption (1.7% on treatment vs. 1.9% without) and fetal or neonatal death (3.5% vs. 4.3%) were lower in the active treatment group, they were uncommon events in both arms of the study. The differences did not reach statistical significance.
 

Maternal morbidity rates lower on treatment

Severe SGA, which was defined as below the 5^th percentile, was also numerically but not significantly higher in the control arm than in the group receiving treatment (5.1% vs. 5.5%), but the incidence of composite adverse maternal events was numerically lower (2.1% vs. 2.8%). The incidences of all components of maternal morbidity, such as maternal death (0.1% vs. 0.2%) pulmonary edema (0.4% vs. 0.9%), heart failure (0.1% vs. 0.1%), and acute kidney injury (0.8% vs. 1.2%), were either lower or the same on active treatment versus no treatment.

According to Dr. Tita, who called CHAP one of the largest and most diverse studies to address the value of treating mild hypertension in pregnancy, the American College of Obstetricians and Gynecologists (ACOG) is evaluating these data for changing their current guidelines for managing hypertension during pregnancy.

“The rate of chronic hypertension during pregnancy has been rising in the United States due to the increase in the average age of pregnant women and the rising rates of obesity,” Dr. Tita commented.

“We definitely needed these data,” said Mary Norine Walsh, MD, medical director, Ascension Saint Vincent Cardiovascular Research Institute, Indianapolis. Not only has the value of treating mild hypertension been unresolved, but Dr. Walsh pointed out that the rates of maternal mortality in the United States are rising and now generally exceed those of many other developed countries.

There are several features in the design of this trial that make the results even more salient to clinical practice, according to Dr. Walsh. This includes the fact that about half of patients enrolled were on Medicaid. As a result, the study confirmed benefit in what Dr. Walsh characterized as a “vulnerable” population.

“We will be busy now to make sure that our [pregnant] patients are achieving these target blood pressures,” Dr. Walsh said. She indicated that CHAP validates the treatment target of 140/90 mm Hg as a standard of care.

The results were published in the New England Journal of Medicine simultaneously with its ACC presentation.

The trial was funded by the National Heart, Lung, and Blood Institute. Dr. Tita reports research grants from Pfizer. Dr. Walsh reports a financial relationship with EBR Systems. Dr. Poppas reports no potential conflicts of interest.

A low-sodium diet was not associated with a reduction in future clinical events in a new study in ambulatory patients with heart failure. But there was a moderate benefit on quality of life and New York Heart Association (NYHA) functional class.

“The guidelines used to strongly recommend a reduction in sodium intake in heart failure patients, but this advice has backed off in recent years because of the lack of data. Most heart failure guidelines now do not make any recommendations on dietary sodium,” he said.

SODIUM-HF was a pragmatic, multinational, open-label, randomized trial conducted in six countries (Australia, Canada, Chile, Colombia, Mexico, and New Zealand), which included 809 patients (median age, 67 years) with chronic heart failure (NYHA functional class II–III) who were receiving optimally tolerated guideline-directed medical treatment. They were randomly assigned to usual care according to local guidelines or a low-sodium diet of less than 100 mmol (<1,500 mg/day). Patients with a baseline sodium intake of less than 1,500 mg/day were excluded.

In the intervention group, patients were asked to follow low-sodium menus developed by dietitians localized to each region. They also received behavioral counseling by trained dietitians or physicians or nurses.

Dietary sodium intake was assessed by using a 3-day food record (including 1 weekend day) at baseline, 6 months, and 12 months in both groups and, for the intervention group, also at 3 and 9 months to monitor and support dietary adherence.

Dr. Ezekowitz explained that although the best method for measuring sodium levels would normally be a 24-hour urine sodium, this would be impractical in a large clinical trial. In addition, he pointed out that urinary sodium is not an accurate measure of actual sodium levels in patients taking diuretics, so it is not a good measure to use in a heart failure population.

“The food record method of assessing sodium levels has been well validated; I think we measured it as accurately as we could have done,” he added.

Results showed that between baseline and 12 months, the median sodium intake decreased from 2,286 mg/day to 1,658 mg/day in the low-sodium group and from 2,119 mg/day to 2,073 mg/day in the usual care group. The median difference between groups was 415 mg/day at 12 months.

By 12 months, events comprising the primary outcome (hospitalization or emergency department visits due to cardiovascular causes or all-cause death) had occurred in 15% of patients in the low-sodium diet group and 17% of those in the usual care group (hazard ratio [HR], 0.89 [95% CI, 0.63 - 1.26]; P = .53).

All-cause death occurred in 6% of patients in the low-sodium diet group and 4% of those in the usual care group (HR, 1.38; P = .32). Cardiovascular-related hospitalization occurred in 10% of the low-sodium group and 12% of the usual care group (HR, 0.82; P = .36), and cardiovascular-related emergency department visits occurred in 4% of both groups (HR, 1.21; P = .60).

The absence of treatment effect for the primary outcome was consistent across most prespecified subgroups, including those with higher vs lower baseline sodium intake. But there was a suggestion of a greater reduction in the primary outcome in individuals younger than age 65 years than in those age 65 years and older.

Quality-of-life measures on the Kansas City Cardiomyopathy Questionnaire (KCCQ) suggested a benefit in the low-sodium group, with mean between-group differences in the change from baseline to 12 months of 3.38 points in the overall summary score, 3.29 points in the clinical summary score, and 3.77 points in the physical limitation score (all differences were statistically significant).

There was no significant difference in 6-minute-walk distance at 12 months between the low-sodium diet group and the usual care group.

NYHA functional class at 12 months differed significantly between groups; the low-sodium diet group had a greater likelihood of improving by one NYHA class than the usual care group (odds ratio, 0.59; P = .0061).

No safety events related to the study treatment were reported in either group.

Dr. Ezekowitz said that to investigate whether longer follow-up may show a difference in events, further analyses are planned at 2 years and 5 years.

Questions on food recall and blinding

Commenting on the findings at the late-breaking clinical trials session at the ACC meeting, Biykem Bozkurt, MD, professor of medicine at Baylor College of Medicine, Houston, congratulated Dr. Ezekowitz on conducting this trial.

“We have been chasing the holy grail of sodium reduction in heart failure for a very long time, so I have to commend you and your team for taking on this challenge, especially during the pandemic,” she said.

But Dr. Bozkurt questioned whether the intervention group actually had a meaningful sodium reduction given that this was measured by food recall and this may have been accounted for by under-reporting of certain food intakes.

Dr. Ezekowitz responded that patients acted as their own controls in that calorie intake, fluid intake, and weight were also assessed and did not change. “So I think we did have a meaningful reduction in sodium,” he said.

Dr. Bozkurt also queried whether the improvements in quality of life and functional status were reliable given that this was an unblinded study.

To this point, Dr. Ezekowitz pointed out that the KCCQ quality-of-life measure was a highly validated instrument and that improvements were seen in these measures at 3, 6, and 12 months. “It is not like these were spurious findings, so I think we have to look at this as a real result,” he argued.

Commenting on the study at an ACC press conference, Mary Norine Walsh, MD, director of the heart failure and cardiac transplantation programs at St. Vincent Heart Center in Indianapolis, said the trial had answered two important questions: that sodium reduction in heart failure may not reduce heart failure hospitalization/death but that patients feel better.

“I think we can safely tell patients that if they slip up a bit they may not end up in hospital,” she added.

This study was funded by the Canadian Institutes of Health Research and the University Hospital Foundation (Edmonton, Alberta, Canada) and the Health Research Council of New Zealand. Dr. Ezekowitz reports research grants from American Regent, Amgen, AstraZeneca, Bayer, Bristol-Myers Squibb/Pfizer, eko.ai, US2.ai, Merck, Novartis, Otsuka, Sanofi, and Servier and consulting fees from American Regent, Amgen, AstraZeneca, Bayer, Bristol-Myers Squibb/Pfizer, Merck, Novartis, Otsuka, Sanofi, and Servier.

Ivermectin, an antiparasitic drug that became popular as an alternative treatment for COVID-19, showed no signs of quelling the disease or reducing patients’ risk of hospitalization, according to results from a large clinical trial published in the New England Journal of Medicine.

The findings pretty much rule out the drug as a treatment for COVID-19, the study authors wrote.

“There’s really no sign of any benefit,” David Boulware, MD, one of the coauthors and an infectious disease specialist at the University of Minnesota, Minneapolis, told the New York Times.

The researchers shared a summary of the results in August 2021 during an online presentation hosted by the National Institutes of Health. The full data hadn’t been published until now.

“Now that people can dive into the details and the data, hopefully that will steer the majority of doctors away from ivermectin toward other therapies,” Dr. Boulware said.

In the trial, the research team compared more than 1,350 people infected with the coronavirus in Brazil who received either ivermectin or a placebo as treatment.

Between March and August 2021, 679 patients received a daily dose of ivermectin over the course of 3 days. The researchers found that ivermectin didn’t reduce the risk that people with COVID-19 would be hospitalized or go to an ED within 28 days after treatment.

In addition, the researchers looked at particular groups to understand if some patients benefited for some reason, such as taking ivermectin sooner after testing positive for COVID-19. But those who took the drug during the first 3 days after a positive coronavirus test ended up doing worse than those in the placebo group. The drug also didn’t help patients recover sooner.

The researchers found “no important effects” of treatment with ivermectin on the number of days people spent in the hospital, the number of days hospitalized people needed mechanical ventilation, or the risk of death.

Ivermectin has become a controversial focal point during the pandemic.

For decades, the drug has been widely used to treat parasitic infections. At the beginning of the pandemic, researchers checked thousands of existing drugs against the coronavirus to determine if a potential treatment already existed. Laboratory experiments on cells suggested that ivermectin might work, the New York Times reported.

But some researchers noted that the experiments worked because a high concentration of ivermectin was used, a much higher dose than would be safe for people. Despite the concerns, some doctors began prescribing ivermectin to patients. After receiving reports of people who needed medical attention, particularly after using formulations intended for livestock, the Food and Drug Administration issued a warning that the drug wasn’t approved to be used for COVID-19.

Researchers around the world have done small clinical trials to understand whether ivermectin treats COVID-19, the newspaper reported. At the end of 2020, Andrew Hill, MD, a virologist at the University of Liverpool in England, reviewed the results from 23 trials and concluded that the drug could lower the risk of death from COVID-19. He published the results in July 2021, but later reports found that many of the studies were flawed, and at least one was fraudulent.

Dr. Hill retracted his original study and began another analysis, which was published in January 2022. In this review, he and his colleagues focused on studies that were least likely to be biased. They found that ivermectin was not helpful.

Recently, Dr. Hill and associates ran another analysis using the new data from the Brazil trial, and once again they saw no benefit.

Several clinical trials are still testing ivermectin as a treatment, the New York Times reported, with results expected in upcoming months. After reviewing the data from the Brazil trial, which tested ivermectin and a variety of other drugs against COVID-19, some infectious disease experts say they’ll likely see more of the same – that ivermectin doesn’t help people with COVID-19.

“I welcome the results of the other clinical trials and will view them with an open mind,” Paul Sax, MD, an infectious disease expert at Brigham and Women’s Hospital, Boston, who has been watching the data on the drug throughout the pandemic, told the New York Times.

“But at some point, it will become a waste of resources to continue studying an unpromising approach,” he said.

Several clinical trials are still testing ivermectin as a treatment, the New York Times reported, with results expected in upcoming months. After reviewing the data from the Brazil trial, which tested ivermectin and a variety of other drugs against COVID-19, some infectious disease experts say they’ll likely see more of the same – that ivermectin doesn’t help people with COVID-19.

“I welcome the results of the other clinical trials and will view them with an open mind,” Paul Sax, MD, an infectious disease expert at Brigham and Women’s Hospital, Boston, who has been watching the data on the drug throughout the pandemic, told the New York Times.

“But at some point, it will become a waste of resources to continue studying an unpromising approach,” he said.

Ivermectin, an antiparasitic drug that became popular as an alternative treatment for COVID-19, showed no signs of quelling the disease or reducing patients’ risk of hospitalization, according to results from a large clinical trial published in the New England Journal of Medicine.

The findings pretty much rule out the drug as a treatment for COVID-19, the study authors wrote.

“There’s really no sign of any benefit,” David Boulware, MD, one of the coauthors and an infectious disease specialist at the University of Minnesota, Minneapolis, told the New York Times.

The researchers shared a summary of the results in August 2021 during an online presentation hosted by the National Institutes of Health. The full data hadn’t been published until now.

“Now that people can dive into the details and the data, hopefully that will steer the majority of doctors away from ivermectin toward other therapies,” Dr. Boulware said.

In the trial, the research team compared more than 1,350 people infected with the coronavirus in Brazil who received either ivermectin or a placebo as treatment.

Between March and August 2021, 679 patients received a daily dose of ivermectin over the course of 3 days. The researchers found that ivermectin didn’t reduce the risk that people with COVID-19 would be hospitalized or go to an ED within 28 days after treatment.

In addition, the researchers looked at particular groups to understand if some patients benefited for some reason, such as taking ivermectin sooner after testing positive for COVID-19. But those who took the drug during the first 3 days after a positive coronavirus test ended up doing worse than those in the placebo group. The drug also didn’t help patients recover sooner.

The researchers found “no important effects” of treatment with ivermectin on the number of days people spent in the hospital, the number of days hospitalized people needed mechanical ventilation, or the risk of death.

Ivermectin has become a controversial focal point during the pandemic.

For decades, the drug has been widely used to treat parasitic infections. At the beginning of the pandemic, researchers checked thousands of existing drugs against the coronavirus to determine if a potential treatment already existed. Laboratory experiments on cells suggested that ivermectin might work, the New York Times reported.

But some researchers noted that the experiments worked because a high concentration of ivermectin was used, a much higher dose than would be safe for people. Despite the concerns, some doctors began prescribing ivermectin to patients. After receiving reports of people who needed medical attention, particularly after using formulations intended for livestock, the Food and Drug Administration issued a warning that the drug wasn’t approved to be used for COVID-19.

Researchers around the world have done small clinical trials to understand whether ivermectin treats COVID-19, the newspaper reported. At the end of 2020, Andrew Hill, MD, a virologist at the University of Liverpool in England, reviewed the results from 23 trials and concluded that the drug could lower the risk of death from COVID-19. He published the results in July 2021, but later reports found that many of the studies were flawed, and at least one was fraudulent.

Dr. Hill retracted his original study and began another analysis, which was published in January 2022. In this review, he and his colleagues focused on studies that were least likely to be biased. They found that ivermectin was not helpful.

Recently, Dr. Hill and associates ran another analysis using the new data from the Brazil trial, and once again they saw no benefit.

BOSTON – Requests for a medical waiver to avoid a second COVID-19 vaccine dose or a booster after cutaneous reactions to the first dose are not justified on the basis of risk, according to an analysis of several large sets of data presented at the annual meeting of the American Academy of Dermatology.

According to the data, “there are no serious adverse consequences from these cutaneous reactions,” said Esther Freeman, MD, PhD, director of Global Health Dermatology, Massachusetts General Hospital, Boston.

This is important because the risk of vaccine hesitancy goes up dramatically in patients who experience reactions to the first vaccine dose, according to follow-up of more than 50,000 employees vaccinated in the Mass General Brigham Healthcare System (MGBHS). According to Dr. Freeman, there was almost a fourfold increase in the rate of second-dose refusals for those with cutaneous reactions and a more than fourfold increase in those who developed angioedema.

Before the data were available, skin reactions were a source of concern among dermatologists and others involved in monitoring vaccine-related adverse events. Injection site reactions (ISRs) are associated with essentially every injectable vaccine, so these were expected, but a small proportion of patients developed large red plaques in the injection arm 7-8 days after the inoculation.

“These delayed reactions caused a lot of initial panic,” said Dr. Freeman, who counted herself among those alarmed about what the reactions might signify. “Was this cellulitis? Would the next dose cause anaphylaxis? We were concerned.”

This concern dissipated with the availability of more data. In a global registry that has so far captured more than 1,000 cutaneous reactions from 52 participating countries, it appears that about 2% of patients have a cutaneous reaction other than an ISR after the first dose. All resolve with minimal skin care or no treatment.

After the second dose, the proportion is lower. If there is a reaction, it typically occurs earlier and resolves more quickly.

“What we have learned is that fewer than half of patients who had a reaction to the first dose have a reaction to the second, and those who did have a reaction had a milder course,” said Dr. Freeman.

These data are “incredibly reassuring” on many levels, she explained. In addition, it allows clinicians to confidently explain to patients that there are no serious sequelae from the rashes, whether immediate or delayed, from the available COVID-19 vaccines.

“Every skin reaction I have seen is something we can treat through,” she added, noting that most reactions resolve with little or no supportive care. Following skin reactions, particularly the delayed lesions, it is not uncommon for patients to refuse a second shot. Some request a medical waiver to avoid further vaccine exposure. According to Dr. Freeman, this is unwarranted.

“I have granted exactly zero waivers,” she said. She explains to patients that these reactions have not been predictive of serious events, such as anaphylaxis. Although the trigger of the hypersensitivity reaction remains unknown, there is no evidence of serious consequences.

Delayed skin reactions are more commonly associated with the Moderna than the Pfizer vaccine. One notable difference between these vaccines is the greater content of mRNA in the Moderna formulation, but Freeman said that this is only one potential hypothesis for higher frequency of reactions to this version of the vaccine.

Patients with a history of allergic disease are more likely to develop a reaction but not significantly more likely to have a reaction that is more difficult to manage, according to Kimberly G. Blumenthal, MD, quality and safety officer for allergy, and codirector of the clinical epidemiology program in the division of rheumatology, allergy, and immunology at Mass General.

Massachusetts General Hospital

Anaphylaxis has been associated with COVD-19 vaccines just as it has with essentially every injectable vaccine, Dr. Blumenthal said during the same session. But the risk is very low, and it stays low even among those with a history of severe hypersensitivity reactions in the past.

Among the data collected from more than 52,000 vaccinated MGBHS employees, 0.9% had a history of severe allergic reaction to a prior vaccine. Of these, 11.6% had an allergic reaction to the COVID-19 vaccine. This was more than twice the 4.6% rate of allergic reactions among employees without a history of allergic reactions, but serious consequences were rare in both groups.

Of those with a reaction to the first dose, all but 2.4% took a subsequent dose. Again, serious reactions were exceedingly rare. These serious reactions did include anaphylaxis and hospitalization in 3% of patients, but there were no fatalities and all resolved.

The absence of serious sequelae from a reaction to a COVID-19 vaccine must be considered within the context of the benefit, which includes protection from death and hospitalization from the virus, according to Dr. Blumenthal. Citing the evidence that first-shot reactions are a source of vaccine hesitancy, she agreed that it is important to educate patients about relative risks.

“Even in our own cohort of MGBHS employees, we have people, including those who had been provaccine in the past, become hesitant,” commented Dr. Blumenthal, who said there are data from the Kaiser Permanente System showing similar vaccine reluctance following a first-shot reaction.

After more than 500 million doses of the Moderna and Pfizer vaccines had been administered worldwide, there was not a single reported death from anaphylaxis. Although Dr. Blumenthal said that an unconfirmed death of this type had been recently reported, she emphasized that this single death, if valid, is dwarfed by the lives saved with vaccination.

Asked about her strategy for counseling patients with vaccine hesitancy, Dr. Freeman said the body of safety data is large and compelling. There is overwhelming evidence of a favorable benefit-to-risk ratio overall and among those with a first-shot reaction.

“I can reassure them on the basis of the data,” Dr. Freeman said in an interview. “Less than half will have a reaction to the second shot and even if they do have a reaction, it is likely to be less severe.”

Although the main message is that vaccination is potentially lifesaving and far outweighs any risks, Freeman specifically gives this message to those hesitant to take a second shot after a first-shot reaction: “I can get you through it.”

Dr. Freeman encouraged health care professionals to report cases of COVID-19 vaccine–related dermatologic side effects to the American Academy of Dermatology / International League of Dermatologic Societies COVID-19 dermatology registry. Dermatologic manifestations of COVID-19 can also be reported to the registry.

Dr. Freeman disclosed receiving grants/research funding from the International League of Dermatologic Societies and from the National Institutes of Health. Dr. Blumenthal disclosed no relevant financial relationships.

There is a link between cannabis exposure during pregnancy and higher fasting glucose levels and adiposity in the offspring in early childhood, a new study suggests.

Research looking at the effect of prenatal exposure to cannabis on offspring is growing. It is known to affect childhood cognition and behavior; however, there is little work to date on how it affects metabolic outcomes, said lead author Brianna F. Moore, PhD.

“Officially, the American Academy of Obstetricians and Gynecologists recommends that women do not use cannabis during pregnancy or while breastfeeding to limit the effects on offspring. There’s really a lot we don’t know, but researchers across the country are starting to look into this more, and there are signs that it isn’t great for the offspring,” Dr. Moore, assistant professor at the Colorado School of Public Health in Aurora, said in an interview.

And she noted that while some women turn to cannabis to manage the challenging symptoms of pregnancy, “Clinicians should encourage pregnant women to refrain from using cannabis; it is best for these pregnant women to talk to their physicians about alternative ways of managing these symptoms.”

The findings were published online March 31 in the Journal of Clinical Endocrinology & Metabolism.
 

Study of mother and 5-year-old child pairs

The researchers assessed 103 sets of mothers and children from the Healthy Start study. At 27 weeks of gestation, the investigators assessed 12 metabolites of cannabis/cannabinoids in urine samples. Results from these samples were used to categorize fetal exposure to cannabis as either not exposed or exposed. They found that about 15% of the mothers had traceable amounts of cannabinoids, suggesting fetal cannabis exposure.

At follow-up, the study team assessed fat-free mass and fat mass using air displacement plethysmography among the offspring around age 5. They used generalized linear models to approximate the relationship between fetal exposure to cannabis with metabolic measures such as insulin, glucose, and homeostatic model assessment of insulin resistance (HOMA-IR), and adiposity measures such as body mass index, fat-free mass, fat mass, adiposity, and BMI z-scores.

The findings showed that, compared with nonexposed offspring, exposed offspring had greater:

• Fasting glucose (5.6 mg/dL; 95% confidence interval [CI], 0.8-10.3).
• Fat-free mass (1.2 kg; 95% CI, 0.4-2.0).
• Fat mass (1.0 kg; 95% CI, 0.3-1.7).
• Adiposity (2.6%; 95% CI, 0.1-5.2).

“This finding may suggest that fetal exposure to cannabis contributes to higher fasting glucose levels via a direct effect on the pancreatic β-cells. However, we cannot draw conclusions about β-cell response to glucose because we did not perform oral glucose tolerance tests,” the study authors wrote.

Notably, however, there was no relationship between BMI z-scores, BMI, or HOMA-IR and fasting insulin, the study team found.

Study limitations include the small sample size and lack of self-report data on cannabis use to differentiate between direct use and exposure to cannabis, Dr. Moore acknowledged.

Given the small sample size, the researchers were unable to look at dose-response, which future studies will focus on, Dr. Moore noted. Future efforts will also focus on comparing the effects of tetrahydrocannabinol (THC) and cannabidiol (CBD), Dr. Moore added.

“This is a relatively new field, so there’s still work to be done. This is just one study, and we need to study this more in other cohorts to confirm our findings,” she concluded.

Dr. Moore has reported no relevant financial relationships.

Given the small sample size, the researchers were unable to look at dose-response, which future studies will focus on, Dr. Moore noted. Future efforts will also focus on comparing the effects of tetrahydrocannabinol (THC) and cannabidiol (CBD), Dr. Moore added.

“This is a relatively new field, so there’s still work to be done. This is just one study, and we need to study this more in other cohorts to confirm our findings,” she concluded.

Dr. Moore has reported no relevant financial relationships.

A new U.K. study shows no link between brain tumors and cell phone use, even among individuals who used their phones every day and/or had used them for over 10 years.

“These results support the accumulating evidence that mobile phone use under usual conditions does not increase brain tumor risk,” study author Kirstin Pirie, MSc, from the cancer epidemiology unit at Oxford (England) Population Health, said in a statement.

However, an important limitation of the study is that it involved only women who were middle-aged and older; these people generally use cell phones less than younger women or men, the authors noted. In this study’s cohort, mobile phone use was low, with only 18% of users talking on the phone for 30 minutes or more each week.

The results were published in the Journal of the National Cancer Institute.

This study is a “welcome addition to the body of knowledge looking at the risk from mobile phones, and specifically in relation to certain types of tumor genesis. It is a well-designed, prospective study that identifies no causal link,” commented Malcolm Sperrin from Oxford University Hospitals, who was not involved in the research.

“There is always a need for further research work, especially as phones, wireless, etc., become ubiquitous, but this study should allay many existing concerns,” he commented on the UK Science Media Centre.

Concerns about a cancer risk, particularly brain tumors, have been circulating for decades, and to date, there have been some 30 epidemiologic studies on this issue.

In 2011, the International Agency for Research on Cancer announced that cell phones are “possibly carcinogenic.” That conclusion was based largely on the results of the large INTERPHONE international case-control study and a series of Swedish studies led by Hardell Lennart, MD.

In the latest article, the U.K. researchers suggest that a “likely explanation for the previous positive results is that for a very slow growing tumor, there may be detection bias if cellular telephone users seek medical advice because of awareness of typical symptoms of acoustic neuroma, such as unilateral hearing problems, earlier than nonusers.

“The totality of human evidence, from observational studies, time trends, and bioassays, suggests little or no increase in the risk of cellular telephone users developing a brain tumor,” the U.K. researchers concluded.

Commenting on the U.K. study, Joachim Schüz, PhD, branch head of the section of environment and radiation at the IARC, noted that “mobile technologies are improving all the time, so that the more recent generations emit substantially lower output power.

“Nevertheless, given the lack of evidence for heavy users, advising mobile phone users to reduce unnecessary exposures remains a good precautionary approach,” Dr. Schuz said in a statement.
 

Details of U.K. study

The U.K. study was conducted by researchers from Oxford Population Health and IARC, who used data from the ongoing UK Million Women Study. This study began in 1996 and has recruited 1.3 million women born from 1935 to 1950 (which amounts to 1 in every 4 women) through the U.K. National Health Service Breast Screening Programme. These women complete regular postal questionnaires about sociodemographic, medical, and lifestyle factors.

Questions about cell phone use were completed by about 776,000 women in 2001 (when they were 50-65 years old). About half of these women also answered these questions about mobile phone use 10 years later, in 2011 (when they were aged 60-75).

The answers indicated that by 2011, the majority of women (75%) aged between 60 and 64 years used a mobile phone, while just under half of those aged between 75 and 79 years used one.

These women were then followed for an average of 14 years through linkage to their NHS records.

The researchers looked for any mention of brain tumors, including glioma, acoustic neuroma, meningioma, and pituitary gland tumors, as well as eye tumors.

During the 14 year follow-up period, 3,268 (0.42%) of the participants developed a brain tumor, but there was no significant difference in that risk between individuals who had never used a mobile phone and those who were mobile phone users. These included tumors in the temporal and parietal lobes, which are the most exposed areas of the brain.

There was also no difference in the risk of developing tumors between women who reported using a mobile phone daily, those who used them for at least 20 minutes a week, and those who had used a mobile phone for over 10 years.

In addition, among the individuals who did develop a tumor, the incidence of right- and left-sided tumors was similar among mobile phone users, even though mobile phone use tends to involve the right side considerably more than the left side, the researchers noted.

The study was funded by the UK Medical Research Council and Cancer Research UK.

Pointing a finger at COVID-19

The battle against COVID-19 is seemingly never ending. It’s been 2 years and still we struggle against the virus. But now, a new hero rises against the eternal menace, a powerful weapon against this scourge of humanity. And that weapon? Finger length.

Before you break out the sad trombone, hear us out. One of the big questions around COVID-19 is the role testosterone plays in its severity: Does low testosterone increase or decrease the odds of contracting severe COVID-19? To help answer that question, English researchers have published a study analyzing finger length ratios in both COVID-19 patients and a healthy control group. That seems random, but high testosterone in the womb leads to longer ring fingers in adulthood, while high estrogen leads to longer index fingers.

PxHere

According to the researchers, those who had significant left hand–right hand differences in the ratio between the second and fourth digits, as well as the third and fifth digits, were significantly more likely to have severe COVID-19 compared with those with more even ratios. Those with “feminized” short little fingers were also at risk. Those large ratio differences indicate low testosterone and high estrogen, which may explain why elderly men are at such high risk for severe COVID-19. Testosterone naturally falls off as men get older.

The results add credence to clinical trials looking to use testosterone-boosting drugs against COVID-19, the researchers said. It also gives credence to LOTME’s brand-new 12-step finger strength fitness routine and our branded finger weights. Now just $19.95! It’s the bargain of the century! Boost your testosterone naturally and protect yourself from COVID-19! We promise it’s not a scam.
 

Some emergencies need a superhero

Last week, we learned about the most boring person in the world. This week just happens to be opposite week, so we’re looking at a candidate for the most interesting person. Someone who can swoop down from the sky to save the injured and helpless. Someone who can go where helicopters fear to tread. Someone with jet engines for arms. Superhero-type stuff.

Richard Browning/Gravity Industries

The Great North Air Ambulance Service (GNAAS), a charitable organization located in the United Kingdom, recently announced that one of its members has completed training on the Gravity Industries Jet Suit. The suit “has two engines on each arm and a larger engine on the back [that] provide up to 317 pounds of thrust,” Interesting Engineering explained.

GNAAS is putting the suit into operation in England’s Lake District National Park, which includes mountainous terrain that is not very hospitable to helicopter landings. A paramedic using the suit can reach hikers stranded on mountainsides much faster than rescuers who have to run or hike from the nearest helicopter landing site.

“Everyone looks at the wow factor and the fact we are the world’s first jet suit paramedics, but for us, it’s about delivering patient care,” GNAAS’ Andy Mawson told Interesting Engineering. Sounds like superhero-speak to us.

So if you’re in the Lake District and have taken a bit of a tumble, you can call a superhero on your cell phone or you can use this to summon one.
 

Why we’re rejecting food as medicine

Humans have been using food to treat ailments much longer than we’ve had the advances of modern medicine. So why have we rejected its worth in our treatment processes? And what can be done to change that? The Center for Food as Medicine and the Hunter College NYC Food Policy Center just released a 335-page report that answers those questions.

phototake/ThinkStock

First, the why: Meals in health care settings are not medically designed to help with the specific needs of the patient. Produce-prescription and nutrition-incentive programs don’t have the government funds to fully support them. And a lot of medical schools don’t even require students to take a basic nutrition course. So there’s a lack of knowledge and a disconnect between health care providers and food as a resource.

Then there’s a lack of trust in the food industry and their validity. Social media uses food as a means of promoting “pseudoscientific alternative medicine” or spreading false info, pushing away legitimate providers. The food industry has had its fingers in food science studies and an almost mafia-esque chokehold on American dietary guidelines. No wonder food for medicine is getting the boot!

To change the situation, the report offers 10 key recommendations on how to advance the idea of incorporating food into medicine for treatment and prevention. They include boosting the funding for research, making hospitals more food-as-medicine focused, expanding federal programs, and improving public awareness on the role nutrition can play in medical treatment or prevention.

So maybe instead of rejecting food outright, we should be looking a little deeper at how we can use it to our advantage. Just a thought: Ice cream as an antidepressant.
 

Being rude is a good thing, apparently

If you’ve ever been called argumentative, stubborn, or unpleasant, then this LOTME is for you. Researchers at the University of Geneva have found that people who are more stubborn and hate to conform have brains that are more protected against Alzheimer’s disease. That type of personality seems to preserve the part of the brain that usually deteriorates as we grow older.

Piqsels

The original hypothesis that personality may have a protective effect against brain degeneration led the investigators to conduct cognitive and personality assessments of 65 elderly participants over a 5-year period. Researchers have been attempting to create vaccines to protect against Alzheimer’s disease, but these new findings offer a nonbiological way to help.

“For a long time, the brain is able to compensate by activating alternative networks; when the first clinical signs appear, however, it is unfortunately often too late. The identification of early biomarkers is therefore essential for … effective disease management,” lead author Panteleimon Giannakopoulos, MD, said in a Study Finds report.

You may be wondering how people with more agreeable and less confrontational personalities can seek help. Well, researchers are working on that, too. It’s a complex situation, but as always, we’re rooting for you, science!

At least now you can take solace in the fact that your elderly next-door neighbor who yells at you for stepping on his lawn is probably more protected against Alzheimer’s disease.

The link between obesity and cancer has increasingly been emphasized in public health messages, but is the current message correct?

“Being overweight or having obesity increases your risk of getting cancer,” warns the U.S. Centers for Disease Control and Prevention. It warns that overweight/obesity is “linked with a higher risk of getting 13 types of cancer ... [which] make up 40% of all cancers diagnosed in the United States each year.”

But that message, which is also promulgated by many cancer organizations, is based on data from observational studies, which have many limitations.

A new study based on Mendelian randomization studies has come to a slightly different conclusion and has found a potential causal association with just six cancers.

In addition, it found an inverse relationship for breast cancer, in which early-life obesity was associated with a reduced risk of breast cancer, and the relationship with obesity was “complicated” for lung and prostate cancer.

The study, headed by Zhe Fang, MBBS, Harvard T. H. Chan School of Public Health, Boston, Mass., was published in the Journal of the National Cancer Institute

“For a seemingly straightforward question of whether excessive body fatness causes cancer, the answer may not be straightforward after all,” writes Song Yao, PhD, professor of oncology, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., in an accompanying editorial

“How to craft a simple public health message to convey the complexity and nuances of the relationships may be a challenge to be grappled with going forward,” he added.

In an interview, Dr. Yao said that it “really depends on what kind of message you want to get out.”

“If you want to talk about cancer overall, as one disease, we all know that a clear association with obesity does not exist,” he said. “It’s not that simple.”

“You really cannot say that obesity increases cancer risk overall,” he said.

For some cancers included in the study, Dr. Yao continued, it was “very clear that obesity increased the risk ... but for some other cancer types, we either don’t have enough data yet or the association is not as consistent.”

This, he said, is especially the case for prostate and lung cancer.

All of this indicates that there is a complex relationship between obesity and cancer risk, he maintains.

“We always think obesity is bad, not only for cancer but also for more common conditions, like hypertension, diabetes, and cardiovascular disease,” Dr. Yao noted. This points to the link between obesity and chronic inflammation, he added.

However, there are also other hypotheses, including synthesis of estrogen in adipose tissue, which may explain the link between obesity and breast cancer risk in older women.

However, in younger women, obesity protects against breast cancer, and “we really don’t know why,” Dr. Yao said.

The new study used Mendelian randomization to examine these relationships. This is a “new tool that we have developed over the past 20 years or so, largely because there is so much data coming from genome-wide association studies,” Dr. Yao explained.

It has “advantages” over other methods, including observational studies. One of its strengths is that it is “not impacted by reverse causality,” because genetic risk does not change over time.

However, he said, it is “quite straightforward to think that the genetics do not change, but at the same time, the environment we live in throughout our life course changes,” and the impact of genetic variants may be “washed out.”

How genetics influences cancer risk may therefore change over time, and it is a “dynamic process,” Dr. Yao commented.

In addition, this approach has its own limitations, he said, because it depends on how much of the variation in a given measure can be attributed to genetic factors.
 

New conclusions

In their study, Dr. Fang and colleagues reviewed 204 meta-analyses of 2,179 individual estimates from 507 cohort or case-control studies. They found “strong evidence” that supports the association between obesity and 11 cancers.

These are esophageal adenocarcinoma, multiple myeloma, and cancers of the gastric cardia, colon, rectum, biliary tract system, pancreas, breast, endometrium, ovary, and kidney.

They note, however, that the associations “may be causal for some malignancies” but that the co-occurrence of obesity with various cancer risk factors means that others may be “susceptible to potential confounding bias.”

To overcome some of these limitations, the team looked to Mendelian randomization studies that examined the association between genetic variants linked to body mass index (BMI), indicating lifetime risk of high BMI, and cancer risk for a range of cancer types.

These Mendelian randomization studies were then compared with the results of large-scale conventional observational studies, as well as with evidence in reports from the International Agency for Research on Cancer and the World Cancer Research Fund–American Institute of Cancer Research, which also include experimental studies.

The researchers say that, overall, the Mendelian randomization studies “further establish the causality of obesity” with six cancer types: colorectal, endometrial, ovarian, kidney, and pancreatic cancer, and esophageal adenocarcinoma.

In addition, these studies further establish the inverse relationship of early-life obesity with breast cancer.

However, the approach could not confirm a positive association between obesity and gallbladder and gastric cardia cancer, as well as multiple myeloma.

“This could be due to low power,” the team suggests, “and larger studies are required.”

With respect to lung cancer, the Mendelian randomization identified a positive association with obesity that supports the inverse association identified in observational studies, that is, that obesity may reduce the risk for lung cancer.

The researchers suggest this may reflect reverse causality related to the loss of lean body mass before diagnosis, as well as confounding by smoking.

For prostate cancer, the evidence was “conflicting” and “implies a complicated role of obesity,” Dr. Zhang and colleagues comment.

The link between obesity and lower prostate-specific antigen levels, they suggest, may result in a detection bias by masking the presence of prostate cancer, or it “could be biological” in origin, owing to reduced androgen levels.

For six cancer types for which a causal relationship with obesity could be established, the effect estimates from the Mendelian randomization studies were stronger than those seen in conventional studies, with the magnitude of risk ranging from 1.14-fold for early-life obesity and breast cancer to 1.37-fold for adult obesity and esophageal adenocarcinoma.

In another editorial accompanying the new study, Graham A. Colditz, MD, DrPH, from Washington University School of Medicine, St. Louis, underlined that childhood and adolescent obesity and their contribution to cancer risk need further attention.

“To reap the reward from past research, we must act to implement effective strategies to reduce childhood and adolescent adiposity, reduce excess weight gain in adult years, and maintain a healthy weight,” he writes.

“This will require us to change the way we live, but COVID-19 has shown we can make changes to how we live and work. Let us keep the changes we have already made, or take on new ones, that will cut our collective cancer toll,” he implores.

No funding for the study was described. Dr. Colditz is supported by the Breast Cancer Research Foundation. No other relevant financial relationships were described.

The link between obesity and cancer has increasingly been emphasized in public health messages, but is the current message correct?

“Being overweight or having obesity increases your risk of getting cancer,” warns the U.S. Centers for Disease Control and Prevention. It warns that overweight/obesity is “linked with a higher risk of getting 13 types of cancer ... [which] make up 40% of all cancers diagnosed in the United States each year.”

But that message, which is also promulgated by many cancer organizations, is based on data from observational studies, which have many limitations.

A new study based on Mendelian randomization studies has come to a slightly different conclusion and has found a potential causal association with just six cancers.

In addition, it found an inverse relationship for breast cancer, in which early-life obesity was associated with a reduced risk of breast cancer, and the relationship with obesity was “complicated” for lung and prostate cancer.

The study, headed by Zhe Fang, MBBS, Harvard T. H. Chan School of Public Health, Boston, Mass., was published in the Journal of the National Cancer Institute

“For a seemingly straightforward question of whether excessive body fatness causes cancer, the answer may not be straightforward after all,” writes Song Yao, PhD, professor of oncology, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., in an accompanying editorial

“How to craft a simple public health message to convey the complexity and nuances of the relationships may be a challenge to be grappled with going forward,” he added.

Among patients with diabetes, women are just as likely as men to suffer from sexual dysfunction, but their issues are overlooked, with the narrative focusing mainly on the impact of this issue on men, say experts.

Women with diabetes can experience reduced sexual desire, painful sex, reduced lubrication, and sexual distress, increasing the risk of depression, and such issues often go unnoticed despite treatments being available, said Kirsty Winkley, PhD, diabetes nurse and health psychologist, King’s College London.

There is also the “embarrassment factor” on the side of both the health care professional and the patient, she said in a session she chaired at the Diabetes UK Professional Conference 2022. Many women with diabetes “wouldn’t necessarily know” that their sexual dysfunction “is related to their diabetes,” she told this news organization.

For women, sexual health conversations are “often about contraception and pregnancy,” as well as menstrual disorders, genital infections, and hormone replacement therapy. “As health care professionals, you’re trained to focus on those things, and you’re not really considering there might be sexual dysfunction. If women aren’t aware that it’s related to diabetes, you’ve got the perfect situation where it goes under the radar.”

However, cochair Debbie Cooke, PhD, health psychologist at the University of Surrey in Guildford, explained that having psychotherapy embedded within the diabetes team and “integrated throughout the whole service” means that the problem can be identified and treatment offered.

The issue is that such integration is “very uncommon” and access needs to be improved, Dr. Cooke said in an interview.
 

Sexual dysfunction major predictor of depression in women

Jacqueline Fosbury, psychotherapy lead at Diabetes Care for You, Sussex Community NHS Foundation Trust, said that “intimate activity is clearly beneficial for emotional and physical health,” as it is associated with increased oxytocin release, the burning of calories, better immunity, and improved sleep.

Sexual dysfunction is common in people with diabetes, she noted. Poor glycemic control can “damage” blood vessels and nerves, causing reduced blood flow and loss of sensation in sexual organs.

A recent study led by Belgian researchers found that among more than 750 adults with diabetes, 36% of men and 33% of women reported sexual dysfunction.

Sexual dysfunction was more common in women with type 1 diabetes, at 36%, compared with 26% for those with type 2 diabetes. The most commonly reported issues were decreased sexual desire, lubrication problems, orgasmic dysfunction, and pain. Body image problems and fear of hypoglycemia also affect sexuality and intimacy, leading to “sexual distress.”

Moreover, Ms. Fosbury said female sexual dysfunction has been identified as a “major predictor” of depression, which in turn reduces libido.

Treatments for women can include lubricants, local estrogen, and medications that are prescribed off-label, such as sildenafil. The same is true of testosterone therapy, which can be used to boost libido.
 

Couples therapy?

Next, Trudy Hannington, a psychosexual therapist with Leger Clinic, Doncaster, U.K., talked about how to use an integrated approach to address sexuality overall in people with diabetes.

She said this should be seen in a biopsychosocial context, with emphasis on the couple, on sensation and communication, and sexual growth, as well as changes in daily routines.

There should be a move away from “penetrative sex,” Ms. Hannington said, with the goal being “enjoyment, not orgasm.” Pleasure should be facilitated and the opportunities for “performance pressure and/or anxiety” reduced.

She discussed the case of Marie, a 27-year-old woman with type 1 diabetes who had been referred with painful sex and vaginal dryness. Marie had “never experienced orgasm,” despite being in a same-sex relationship with Emily.

Marie’s treatment involved a sexual growth program, to which Emily was invited, as well as recommendations to use lubricants, vibrators, and to try sildenafil.
 

Prioritize women

Ms. Fosbury reiterated that, in men, sexual dysfunction is “readily identified as a complication of diabetes” and is described as “traumatic” and “crucial to well-being.” It is also seen as “easy to treat” with medication, such as that for erectile dysfunction.

It is therefore crucial to talk to women with diabetes about possible sexual dysfunction, and the scene must be set before the appointment to explain that the subject will be broached. In addition, handouts and leaflets should be available for patients in the clinic so they can read about female sexual health and to lower the stigma around discussing it.

“Cultural stereotypes diminish the importance of female sexuality and prevent us from providing equal consideration to the sexual difficulties of our patients,” she concluded.

No funding declared. No relevant financial relationships declared.
