Merck’s COVID-19 pill may be less effective than first hoped
According to an analysis by scientists at the Food and Drug Administration, the experimental pill cut the risk of hospitalization or death from COVID-19 by about 30%, compared to a placebo, and the pill showed no benefit for people with antibodies against COVID-19 from prior infection.
The updated analysis showed 48 hospitalizations or deaths among study participants who were randomly assigned to take the antiviral drug, compared to 68 among those who took a placebo.
Those results come from the full set of 1,433 patients who were randomized in the clinical trial, which just became available last week.
Initial results from the first 775 patients enrolled in the clinical trial, which were issued in a company news release in October, had said the drug cut the risk of hospitalization or death for patients at high risk of severe disease by about 50%.
Merck has been producing millions of doses of molnupiravir, which is the first antiviral pill to treat COVID-19 infections. The United Kingdom’s drug regulator authorized use of the medication in early November. The company said it expected to distribute the medication globally by the end of 2021.
In October, two Indian drug companies halted late-stage clinical trials of a generic version of molnupiravir after the studies failed to find any benefit to patients with moderate COVID-19. Trials in patients with milder symptoms are still ongoing.
On Nov. 27, the New England Journal of Medicine postponed its planned early release of the molnupiravir study results, citing “new information.”
The medication is designed to be given as four pills taken every 12 hours for 5 days. It’s most effective when taken within the first few days of new symptoms, something that requires convenient and affordable testing.
The new results seem to put molnupiravir far below the effectiveness of existing treatments.
The infused monoclonal antibody cocktail REGEN-COV, which the FDA has already authorized for emergency use, is about 85% effective at preventing hospitalization or death in patients who are at risk for severe COVID-19 outcomes, and it appears to be just as effective in people who already have antibodies against COVID-19, which is why it is being given to both vaccinated and unvaccinated patients, the FDA said.
In early November, Pfizer said its experimental antiviral pill Paxlovid cut the risk of hospitalization or death by 89%.
In briefing documents posted ahead of an advisory committee meeting Nov. 30, the FDA highlights other potential safety issues with the Merck drug, which works by causing the virus to make mistakes as it copies itself, eventually causing the virus to mutate itself to death.
The agency has asked the advisory committee to weigh in on the right patient population for the drug: Should pregnant women get it? Could the drug harm a developing fetus?
Should vaccinated people with breakthrough infections get it? Would it work for them? People with reduced immune function are more likely to get a breakthrough infection. They’re also more likely to shed virus for a longer period of time, making them perfect incubators for variants. What could happen if we give this type of patient a drug that increases mutations?
And what about mutations caused by the medication? Could they increase the potential for more variants? The agency concluded the risk of this happening was low.
In animal studies, the drug impacted bone formation. For this reason, the agency has agreed with the drug company that molnupiravir should not be given to anyone under the age of 18.
Aside from these concerns, the FDA says there were no major safety issues among people who took part in the clinical trial, though they acknowledge that number is small.

Did prior authorization refusals lead to this patient’s death?
Ramy Sedhom, MD, a medical oncologist and a palliative care physician at Penn Medicine Princeton Health in Plainsboro, N.J., will always wonder if prior authorization refusals led to his patient’s death.
The patient had advanced gastric cancer and the insurer initially denied a PET scan to rule out metastatic disease. When the scan was eventually allowed, it revealed that the cancer had spread.
Standard treatment would have been difficult for the patient, an older individual with comorbidities. But Dr. Sedhom knew that a European study had reported equal efficacy and fewer side effects with a reduced chemotherapy regimen, and he thought that was the best approach in this situation.
The insurer disagreed with Dr. Sedhom’s decision and, while the two argued, the patient’s symptoms worsened. He was admitted to the hospital, where he experienced a decline in function, common for older patients. “Long story short, he was never able to seek treatment and then transitioned to hospice,” Dr. Sedhom said. “It was one of those situations where there was a 3- to 4-week delay in what should have been standard care.”
. Nearly 4 years after major organizations — American Hospital Association, America’s Health Insurance Plans, American Medical Association, Blue Cross Blue Shield Association, and others — signed a consensus statement agreeing to improve the prior authorization process, physicians say little progress has been made.
Indeed, 83% of physicians say that the number of prior authorizations required for prescription medications and medical services has increased over the last 5 years, according to survey results released earlier this year.
“It’s decidedly worse — there’s no question about it,” said Andrew R. Spector, MD, a neurologist and sleep medicine specialist at Duke Health in Durham, N.C. “Drugs that I used to get without prior authorizations now require them.”
When Vignesh I. Doraiswamy, MD, an internal medicine hospitalist at the Ohio State University Wexner Medical Center in Columbus, discharged a patient with Clostridioides difficile infection, he followed clinical guidelines to prescribe vancomycin for 10 to 14 days. “And the insurance company said, ‘Well, yeah, we only authorize about 5 days,’ which just makes no sense,” Dr. Doraiswamy said. “There’s nowhere in any literature that says 5 days is sufficient. What worries me is that is the standard of care we are supposed to give and yet we are unable to.”
Yash B. Jobanputra, MD, a cardiology fellow at Saint Vincent Hospital in Worcester, Mass., laments that prior authorization is used in situations that simply do not make common sense. During his residency, a woman who had tested positive for the BRCA gene mutation with a strong family history of breast cancer needed a breast ultrasound and an MRI scan every 6 months to 1 year. Despite the documentation that she was at extremely high risk for developing breast cancer, he had to go through prior authorization every time she was due for new images.
“I had to call the insurance company, they would put me on hold, I would wait to speak to a physician — and the end response would be, ‘Yeah, this is what needs to be done,’” he said. “But having established her positive status once should be enough really. I shouldn’t have to go through the circus all over again.”
Prior authorization is also being used for routine diagnostics, such as a Holter monitor for patients complaining of heart palpitations. “Depending on the insurance, for some patients we can give it to them in the clinic right away,” Dr. Jobanputra said. “Whereas some others we have to wait until we get prior authorization from the insurance company and the patient has to come back again to the hospital to get the monitor. That is a delay in patient care.”
The delays also extend to emergency care, Dr. Doraiswamy said. He cites the example of a heart attack patient who needed an emergency heart catheterization but ran into a prior authorization delay. “I just said, ‘Try your best not to get stressed’ which is not easy for a patient finding out their stay wasn’t covered when they had just been through a heart attack,” he said. “Then I spent 20 to 30 minutes — most of it on hold — to answer the question ‘Why did this patient need to get admitted?’ “
Physicians feel disrespected because that type of prior authorization hassle is just busywork. “Rarely is a valid stay that was initially denied, not eventually accepted,” Dr. Doraiswamy said. “But why couldn’t they have just seen that the guy had a heart attack and he obviously needed to be in the hospital?”
For Dr. Spector, the Duke Health sleep medicine specialist, prior authorization is not just a speed bump, it’s a full stop. Insurers have started mandating a multiple sleep latency test (MSLT) to confirm narcolepsy before covering medication to treat the condition. “We know that the MSLT is very often wrong,” he said. “There are a lot of times we’re dealing with patients with narcolepsy who simply don’t meet the testing criteria that the insurance requires, and payers will not accept our clinical judgment.”
In his view, the prior authorization landscape is worsening — and not only because a “faulty test” is being used to deny treatment. “The appeal process is worse,” Dr. Spector said. “I used to be able to get on the phone and do a peer-to-peer review with a physician who I could reason with… but that doesn’t happen anymore. There is virtually no way to bypass these blanket rules.”
Other survey findings also stand in direct contradiction of the 2018 consensus agreement:
A large majority (87%) of physicians report that prior authorization interferes with continuity of care, even though the industry groups agreed that patients should be protected from treatment disruption when there is a formulary or treatment-coverage change.
Despite a consensus to encourage transparency and easy accessibility of prior authorization requirements, 68% of physicians reported that it is difficult to determine whether a prescription medication requires prior authorization, and 58% report that it’s difficult for medical services.
Phone and fax are the most commonly used methods for completing prior authorizations, despite agreement that electronic prior authorization, using existing national standard transactions, should be accelerated. Fewer than one quarter of physicians said that their electronic health record system supports electronic prior authorization for prescription medications.
Dr. Spector wants to see legislation that forces insurers to live up to some of the tenets of the 2018 consensus statement. In September, a new Texas law went into effect, exempting physicians from prior authorization if, during the previous six months, 90% of their treatments met an insurer›s medical necessity criteria. In January, the recently approved Prior Authorization Reform Act in Illinois will reduce the number of services subject to prior authorization, mandate a prior authorization decision within 5 days, and set disciplinary measures for health plans that do not comply, among other things.
“What gives me hope is that at least somewhere in the country, somebody is doing something,” Dr. Spector said. “And if it goes well, maybe other insurers will adopt it. I’m really hoping they demonstrate that the money they can save on the administration of all the appeals and prior authorization paperwork can actually go into caring for patients.”
In addition to state-level action, reform may also be advancing at the federal level. In October, a bill was introduced in the U.S. Senate that mirrors a prior authorization reform bill introduced in the House of Representatives last May. Both bills have broad bipartisan support; the House bill has more than 235 co-sponsors.
In an interview with this news organization, Rep. Ami Bera, MD, (D-CA) said it is “very realistic” that the bill will become law during this session of Congress. “We do think this bill will get marked up in committee and hopefully we can get it to the floor either as a stand-alone bill where we know we have the votes to pass it or as part of a larger legislative package,” he said.
If approved, the Improving Seniors’ Timely Access to Care Act of 2021 would require that Medicare Advantage plans minimize the use of prior authorization for routinely approved services; require real-time decisions for certain requests; report the extent of their use of prior authorization and their rate of approvals or denials, among other things; and establish an electronic prior authorization system.
Medicare Advantage plans are private insurers that are regulated by the Centers for Medicare & Medicaid Services (CMS), which will create the specific rules and penalties associated with the reforms, if they become law. “One would presume that a condition of being a Medicare Advantage plan is that you’re going to have to comply with these new regulations,” said Katie Orrico, senior vice president of health policy and advocacy for the American Association of Neurological Surgeons and Congress of Neurological Surgeons (AANS/CNS). “So they will have some amount of teeth in the form of a mandate.”
The AANS and CNS are part of the Regulatory Relief Coalition, a group of 14 national physician specialty organizations. Winning prior authorization reform in the Medicare Advantage plans is part of its bigger strategy. “If those commercial plans have to follow a set of rules and processes for Medicare, then why not just expand those same processes to all other parts of their business?” Ms. Orrico said.
Despite his frustration with their prior authorization processes, Dr. Doraiswamy, the Ohio State hospitalist, agrees that working to improve insurers’ practices is the best way forward. “It’s so easy to make them look like these evil, giant conglomerations that exist solely to suck money and not care about anyone’s health, but I don’t know if that’s necessarily the case,” he said. “We really have to figure out how best to work with insurance companies to make sure that, while they are profit-generating institutions, that [profit] shouldn’t come at the cost of patient care.”

In his view, the prior authorization landscape is worsening — and not only because a “faulty test” is being used to deny treatment. “The appeal process is worse,” Dr. Spector said. “I used to be able to get on the phone and do a peer-to-peer review with a physician who I could reason with… but that doesn’t happen anymore. There is virtually no way to bypass these blanket rules.”
Other survey findings also stand in direct contradiction of the 2018 consensus agreement:
A large majority (87%) of physicians report that prior authorization interferes with continuity of care, even though the industry groups agreed that patients should be protected from treatment disruption when there is a formulary or treatment-coverage change.
Despite a consensus to encourage transparency and easy accessibility of prior authorization requirements, 68% of physicians reported that it is difficult to determine whether a prescription medication requires prior authorization, and 58% report that it’s difficult for medical services.
Phone and fax are the most commonly used methods for completing prior authorizations, despite agreement that electronic prior authorization, using existing national standard transactions, should be accelerated. Fewer than one quarter of physicians said that their electronic health record system supports electronic prior authorization for prescription medications.
Dr. Spector wants to see legislation that forces insurers to live up to some of the tenets of the 2018 consensus statement. In September, a new Texas law went into effect, exempting physicians from prior authorization if, during the previous six months, 90% of their treatments met an insurer›s medical necessity criteria. In January, the recently approved Prior Authorization Reform Act in Illinois will reduce the number of services subject to prior authorization, mandate a prior authorization decision within 5 days, and set disciplinary measures for health plans that do not comply, among other things.
“What gives me hope is that at least somewhere in the country, somebody is doing something,” Dr. Spector said. “And if it goes well, maybe other insurers will adopt it. I’m really hoping they demonstrate that the money they can save on the administration of all the appeals and prior authorization paperwork can actually go into caring for patients.”
In addition to state-level action, reform may also be advancing at the federal level. In October, a bill was introduced in the U.S. Senate that mirrors a prior authorization reform bill introduced in the House of Representatives last May. Both bills have broad bipartisan support; the House bill has more than 235 co-sponsors.
In an interview with this news organization, Rep. Ami Bera, MD, (D-CA) said it is “very realistic” that the bill will become law during this session of Congress. “We do think this bill will get marked up in committee and hopefully we can get it to the floor either as a stand-alone bill where we know we have the votes to pass it or as part of a larger legislative package,” he said.
If approved, the Improving Seniors’ Timely Access to Care Act of 2021 would require that Medicare Advantage plans minimize the use of prior authorization for routinely approved services; require real-time decisions for certain requests; report the extent of their use of prior authorization and their rate of approvals or denials, among other things; and establish an electronic prior authorization system.
Medicare Advantage plans are private insurers that are regulated by the Centers for Medicare & Medicaid Services (CMS), which will create the specific rules and penalties associated with the reforms, if they become law. “One would presume that a condition of being a Medicare Advantage plan is that you’re going to have to comply with these new regulations,” said Katie Orrico, senior vice president of health policy and advocacy for the American Association of Neurological Surgeons and Congress of Neurological Surgeons (AANS/CNS). “So they will have some amount of teeth in the form of a mandate.”
The AANS and CNS are part of the Regulatory Relief Coalition, a group of 14 national physician specialty organizations. Winning prior authorization reform in the Medicare Advantage plans is part of its bigger strategy. “If those commercial plans have to follow a set of rules and processes for Medicare, then why not just expand those same processes to all other parts of their business?” Ms. Orrico said.
Despite his frustration with their prior authorization processes, Dr. Doraiswamy, the Ohio State hospitalist, agrees that working to improve insurers’ practices is the best way forward. “It’s so easy to make them look like these evil, giant conglomerations that exist solely to suck money and not care about anyone’s health, but I don’t know if that’s necessarily the case,” he said. “We really have to figure out how best to work with insurance companies to make sure that, while they are profit-generating institutions, that [profit] shouldn’t come at the cost of patient care.”

Does vitamin D benefit only those who are deficient?
, suggests a new large-scale analysis.
Data on more than 380,000 participants gathered from 35 studies showed that, overall, there is no significant relationship between 25(OH)D concentrations, a clinical indicator of vitamin D status, and the incidence of coronary heart disease (CHD), stroke, or all-cause death, in a Mendelian randomization analysis.
However, Stephen Burgess, PhD, and colleagues showed that, in vitamin D–deficient individuals, each 10 nmol/L increase in 25(OH)D concentrations reduced the risk of all-cause mortality by 31%.
The research, published in The Lancet Diabetes & Endocrinology, also suggests there was a nonsignificant link between 25(OH)D concentrations and stroke and CHD, but again, only in vitamin D deficient individuals.
In an accompanying editorial, Guillaume Butler-Laporte, MD, and J. Brent Richards, MD, praise the researchers on their study methodology.
They add that the results “could have important public health and clinical consequences” and will “allow clinicians to better weigh the potential benefits of supplementation against its risk,” such as financial cost, “for better patient care – particularly among those with frank vitamin D deficiency.”
They continue: “Given that vitamin D deficiency is relatively common and vitamin D supplementation is safe, the rationale exists to test the effect of vitamin D supplementation in those with deficiency in large-scale randomized controlled trials.”
However, Dr. Butler-Laporte and Dr. Richards, of the Lady Davis Institute, Jewish General Hospital, Montreal, also note the study has several limitations, including the fact that the lifetime exposure to lower vitamin D levels captured by Mendelian randomization may result in larger effect sizes than in conventional trials.
Prior RCTS underpowered to detect effects of vitamin D supplements
“There are several potential mechanisms by which vitamin D could be protective for cardiovascular mortality, including mechanisms linking low vitamin D status with hyperparathyroidism and low serum calcium and phosphate,” write Dr. Burgess of the MRC Biostatistics Unit, University of Cambridge (England), and coauthors.
They also highlight that vitamin D is “further implicated in endothelial cell function” and affects the transcription of genes linked to cell division and apoptosis, providing “potential mechanisms implicating vitamin D for cancer.”
The researchers note that, while epidemiologic studies have “consistently” found a link between 25(OH)D levels and increased risk of cardiovascular disease, all-cause mortality, and other chronic diseases, several large trials of vitamin D supplementation have reported “null results.”
They argue, however, that many of these trials have recruited individuals “irrespective of baseline 25(OH)D concentration” and have been underpowered to detect the effects of supplementation.
To overcome these limitations, the team gathered data from the UK Biobank, the European Prospective Investigation Into Cancer and Nutrition Cardiovascular Disease (EPIC-CVD) study, 31 studies from the Vitamin D Studies Collaboration (VitDSC), and two Copenhagen population-based studies.
They first performed an observational study that included 384,721 individuals from the UK Biobank and 26,336 from EPIC-CVD who had a valid 25(OH)D measurement and no previously known cardiovascular disease at baseline.
Researchers also included 67,992 participants from the VitDSC studies who did not have previously known cardiovascular disease. They analyzed 25(OH)D concentrations, conventional cardiovascular risk factors, and major incident cardiovascular morbidity and mortality using individual participant data.
The results showed that, at low 25(OH)D concentrations, there was an inverse association between 25(OH)D and incident CHD, stroke, and all-cause mortality.
Next, the team conducted a Mendelian randomization analysis on 333,002 individuals from the UK Biobank and 26,336 from EPIC-CVD who were of European ancestry and had both a valid 25(OH)D measurement and genetic data that passed quality-control steps.
Information on 31,362 participants in the Copenhagen population-based studies was also included, giving a total of 386,406 individuals, of whom 33,546 had CHD, 18,166 had a stroke, and 27,885 died.
The mean age of participants ranged from 54.8 to 57.5 years, and between 53.4% and 55.4% were female.
Up to 7% of study participants were vitamin D deficient
The 25(OH)D analysis indicated that 3.9% of UK Biobank and 3.7% of Copenhagen study participants were deficient, compared with 6.9% in EPIC-CVD.
Across the full range of 25(OH)D concentrations, there was no significant association between genetically predicted 25(OH)D levels and CHD, stroke, or all-cause mortality.
However, restricting the analysis to individuals deemed vitamin D deficient (25[OH]D concentration < 25 nmol/L) revealed there was “strong evidence” for an inverse association with all-cause mortality, at an odds ratio per 10 nmol/L increase in genetically predicted 25(OH)D concentration of 0.69 (P < .0001), the team notes.
There were also nonsignificant associations between being in the deficient stratum and CHD, at an odds ratio of 0.89 (P = .14), and stroke, at an odds ratio of 0.85 (P = .09).
Further analysis suggests the association between 25(OH)D concentrations and all-cause mortality has a “clear threshold shape,” the researchers say, with evidence of an inverse association at concentrations below 40 nmol/L and null associations above that threshold.
They acknowledge, however, that their study has several potential limitations, including the assumption in their Mendelian randomization that the “only causal pathway from the genetic variants to the outcome is via 25(OH)D concentrations.”
Moreover, the genetic variants may affect 25(OH)D concentrations in a different way from “dietary supplementation or other clinical interventions.”
They also concede that their study was limited to middle-aged participants of European ancestries, which means the findings “might not be applicable to other populations.”
The study was funded by the British Heart Foundation, Medical Research Council, National Institute for Health Research, Health Data Research UK, Cancer Research UK, and International Agency for Research on Cancer. Dr. Burgess has reported no relevant financial relationships. Disclosures for the other authors are listed with the article.

U.S. obesity rates soar in early adulthood
Obesity rates among “emerging adults” aged 18-25 have soared in the United States in recent decades with the mean body mass index (BMI) for these young adults now in the overweight category, according to research highlighting troubling trends in an often-overlooked age group.
While similar patterns have been observed in other age groups, including adolescents (ages 12-19) and young adults (ages 20-39) across recent decades, emerging adulthood tends to get less attention in the evaluation of obesity trends.
“Emerging adulthood may be a key period for preventing and treating obesity given that habits formed during this period often persist through the remainder of the life course,” write the authors of the study, which was published online Nov. 23 in JAMA.
“There is an urgent need for research on risk factors contributing to obesity during this developmental stage to inform the design of interventions as well as policies aimed at prevention,” they add.
They found that by 2018 a third of all young adults had obesity, compared with just 6% at the beginning of the study periods in 1976.
Studying the ages of transition
The findings are from an analysis of 8,015 emerging adults aged 18-25 in the cross-sectional National Health and Nutrition Examination Survey (NHANES), including NHANES II (1976-1980), NHANES III (1988-1994), and the continuous NHANES cycles from 1999 through 2018.
About half (3,965) of participants were female, 3,037 were non-Hispanic Black, and 2,386 met the criteria for household poverty.
The results showed substantial increases in mean BMI among emerging adults from a level in the normal range, at 23.1 kg/m2, in 1976-1980, increasing to 27.7 kg/m2 (overweight) in 2017-2018 (P = .006).
The prevalence of obesity (BMI 30.0 kg/m2 or higher) in the emerging adult age group soared from 6.2% between 1976-1980 to 32.7% in 2017-2018 (P = .007).
Meanwhile, the rate of those with normal/healthy weight (BMI 18.5-24.9 kg/m2) dropped from 68.7% to 37.5% (P = .005) over the same period.
Sensitivity analyses that were limited to continuous NHANES cycles showed similar results.
First author Alejandra Ellison-Barnes, MD, MPH, said the trends are consistent with rising obesity rates in the population as a whole – other studies have shown increases in obesity among children, adolescents, and adults over the same period – but are nevertheless striking, she stressed.
Young adults now fall into overweight category
“While we were not surprised by the general trend, given what is known about the increasing prevalence of obesity in both children and adults, we were surprised by the magnitude of the increase in prevalence and that the mean BMI in this age group now falls in the overweight range,” Dr. Ellison-Barnes, of the Division of General Internal Medicine, Johns Hopkins University School of Medicine, Baltimore, told this news organization.
She said she is not aware of other studies that have looked at obesity trends specifically among emerging adults.
However, considering the substantial life changes and growing independence, the life stage is important to understand in terms of dietary/lifestyle patterns.
“We theorize that emerging adulthood is a critical period for obesity development given that it is a time when individuals are often undergoing major life transitions such as leaving home, attending higher education, entering the workforce, and developing new relationships,” she emphasized.
As far as causes are concerned, “societal and cultural trends in these areas over the past several decades may have played a role in the observed changes,” she speculated.
The study population was limited to non-Hispanic Black and non-Hispanic White individuals due to changes in how NHANES assessed race and ethnicity over time. Therefore, a study limitation is that the patterns observed may not be generalizable to other races and ethnicities, the authors note.
However, considering the influence lifestyle changes can have, early adulthood “may be an ideal time to intervene in the clinical setting to prevent, manage, or reverse obesity to prevent adverse health outcomes in the future,” Dr. Ellison-Barnes said.

The prevalence of obesity (BMI 30.0 kg/m2 or higher) in the emerging adult age group soared from 6.2% between 1976-1980 to 32.7% in 2017-2018 (P = .007).
Meanwhile, the rate of those with normal/healthy weight (BMI 18.5-24.9 kg/m2) dropped from 68.7% to 37.5% (P = .005) over the same period.
Sensitivity analyses that were limited to continuous NHANES cycles showed similar results.
First author Alejandra Ellison-Barnes, MD, MPH, said the trends are consistent with rising obesity rates in the population as a whole – other studies have shown increases in obesity among children, adolescents, and adults over the same period – but are nevertheless striking, she stressed.
Young adults now fall into overweight category
“While we were not surprised by the general trend, given what is known about the increasing prevalence of obesity in both children and adults, we were surprised by the magnitude of the increase in prevalence and that the mean BMI in this age group now falls in the overweight range,” Dr. Ellison-Barnes, of the Division of General Internal Medicine, Johns Hopkins University School of Medicine, Baltimore, told this news organization.
She said she is not aware of other studies that have looked at obesity trends specifically among emerging adults.
However, considering the substantial life changes and growing independence, the life stage is important to understand in terms of dietary/lifestyle patterns.
“We theorize that emerging adulthood is a critical period for obesity development given that it is a time when individuals are often undergoing major life transitions such as leaving home, attending higher education, entering the workforce, and developing new relationships,” she emphasized.
As far as causes are concerned, “societal and cultural trends in these areas over the past several decades may have played a role in the observed changes,” she speculated.
The study population was limited to non-Hispanic Black and non-Hispanic White individuals due to changes in how NHANES assessed race and ethnicity over time. Therefore, a study limitation is that the patterns observed may not be generalizable to other races and ethnicities, the authors note.
However, considering the influence lifestyle changes can have, early adulthood “may be an ideal time to intervene in the clinical setting to prevent, manage, or reverse obesity to prevent adverse health outcomes in the future,” Dr. Ellison-Barnes said.
Dr. Ellison-Barnes has reported no relevant financial relationships.

Hypertension may double the risk of late-onset epilepsy
new research suggests.
After excluding individuals with normal blood pressure who were taking antihypertensive medication, investigators found hypertension was linked to an almost 2.5-fold higher risk of epilepsy.
“Our findings further expand upon our knowledge of the negative effects hypertension has on brain health and, regarding epilepsy, that effect may be starting even in midlife,” said co–lead author Maria Stefanidou, MD, MSc, of Boston University.
“Practicing clinicians should be vigilant to diagnose hypertension, discuss with patients all potential long-term brain health outcomes, and need for treatment. Furthermore, in those presenting with new-onset epilepsy later in life, screening for potentially undiagnosed hypertension should be included in the initial workup,” she said.
The study was published online Nov. 17, 2021, in Epilepsia.
Unknown etiology
“New-onset epilepsy risk increases with increasing age over the age of 65 and can affect 15-20 per 1,000 older individuals. Although the most common causes for seizures in this age group are prior history of stroke and presence of dementia, for about 30%-40% of patients, the etiology of seizures remains unknown,” Dr. Stefanidou said.
“We wanted to study if modifiable vascular risk factors that are known to contribute both to vascular brain aging and to neurodegeneration may directly predict the development of epilepsy, even in the absence of clinical stroke or dementia,” she added.
To investigate, the researchers turned to data from participants in the Offspring Cohort of the Framingham Health Study (FHS). The original FHS was an ongoing longitudinal community-based study that first began in 1948. Offspring of the original cohort and their spouses (n = 5,124) were enrolled in the Offspring Cohort in 1971, with surveillance of these second-generation participants based on exam visits occurring every 4 years.
The study included participants who had attended exam 5 (1991-1995), were age 45 years or older, had available vascular risk factor (VRF) data, and available follow-up data on epilepsy status (n = 2,986; mean age, 58 years; 48% male).
The investigators conducted two statistical analyses. In the primary model, they adjusted for age and gender, while in a secondary model they also adjusted for prevalent and interim stroke. They also conducted an analysis that excluded participants treated with antihypertensive medication and had normal blood pressure.
Plausible mechanisms
During a mean follow-up of 19.2 years, 55 incident epilepsy cases were identified. The mean age of these patients was 73.8 years.
In the primary model, hypertension was associated with an almost twofold higher risk of developing epilepsy (hazard ratio, 1.97; 95% confidence interval, 1.13-3.45; P = .017).
Interestingly, the Framingham Stroke Risk Profile – a calculation based on an array of factors, including age/sex, systolic blood pressure, antihypertensive therapy, diabetes, history of cardiovascular disease, atrial fibrillation, and cigarette smoking – was not associated with incident epilepsy, and there was no other significant associated between any of the other VRFs when looked at independently.
When the researchers adjusted for prevalent and interim stroke, they continued to find an almost twofold higher risk of developing epilepsy (HR 1.93; 95% CI, 1.10-3.37; P = .022). An analysis that adjusted for competing risk of death obtained similar findings (HR, 1.98; 95% CI, 1.03-3.81; P = .042).
The model that excluded patients receiving antihypertensive treatment, whose blood pressure readings were normal (n = 2,162; 50 incident epilepsy cases) showed an even stronger association (HR, 2.44; 95% CI, 1.36-4.35; P = .003).
“Our results are based on an epidemiological, observational study, therefore our findings point to an association between hypertension and new-onset epilepsy later in life,” said Dr. Stefanidou.
She noted that because it was an observational study, “a cause-effect relationship cannot be established based on these results, but there is growing evidence from our, as well as other, similar cohorts that hypertension, a modifiable vascular risk factor, may indeed be an independent predictor of late-onset epilepsy.”
There are “plausible mechanisms” that support both a direct, and indirect, role of hypertension – for example, through accumulation of small vessel disease in the brain – but further research will be necessary to elucidate the exact mechanisms involved in the process,” she added.
‘Welcome addition’
In a joint comment, Hedley C.A. Emsley, PhD, professor of clinical neuroscience, Lancaster (England) University, and Jasmine Wall, MBBChir, academic clinical fellow in neurology, Lancaster University, described the study as a “welcome addition to this field,” noting that the Framingham Heart Study “lends itself well to an embedded observational study of this nature of late-onset epilepsy.”
Dr. Emsley and Dr. Wall, who were not involved in the research, said that the “apparent magnitude of increased late-onset epilepsy risk association with hypertension in the Stefanidou et al study is quite striking,” even allowing for the “relatively small sample size,” since their analysis and findings appear to “withstand exclusion of individuals who became normotensive on antihypertensive treatment.”
They noted that in recent years there has been a growing body of evidence highlighting the importance of hypertension in late-onset epilepsy epileptogenesis with subclinical cerebrovascular diseases, including “otherwise occult cerebral small vessel disease believed to be a frequent cause.”
The mechanisms “remain unclear,” but they could potentially include diffuse cerebral microangiopathy, structural and physiological changes, and/or blood-brain barrier dysfunction and leakage, they suggested.
“Although there is no current consensus over an age threshold that defines ‘late onset,’ we would argue that age thresholds used in such studies of late-onset epilepsy should be lower, to avoid missing younger adults at risk through vascular mechanisms,” Dr. Emsley and Dr. Wall added.
The study authors suggest that “potential pathophysiologic mechanisms can further be explored in future experimental studies and clinical trials.”
This study was funded by grants from the National Institutes of Health and Finding a Cure for Epilepsy/Seizures. Dr. Stefanidou disclosed relevant financial relationships. Dr. Emsley and Dr. Wall disclosed no relevant financial relationships.

Fueling an ‘already raging fire’: Fifth COVID surge approaches
“A significant rise in cases just before Thanksgiving is not what we want to be seeing,” said Stephen Kissler, PhD, a postdoctoral researcher and data modeler at the Harvard TH Chan School of Public Health in Boston.
Dr. Kissler said he’d rather see increases in daily cases coming 2 weeks after busy travel periods, as that would mean they could come back down as people returned to their routines.
Seeing big increases in cases ahead of the holidays, he said, “is sort of like adding fuel to an already raging fire.”
Last winter, vaccines hadn’t been rolled out as the nation prepared for Thanksgiving. COVID-19 was burning through family gatherings.
But now that two-thirds of Americans over age 5 are fully vaccinated and booster doses are approved for all adults, will a rise in cases translate, once again, into a strain on our still thinly stretched healthcare system?
Experts say the vaccines are keeping people out of the hospital, which will help. And new antiviral pills are coming that seem to be able to cut a COVID-19 infection off at the knees, at least according to early data. A U.S. Food and Drug Administration panel meets next week to discuss the first application for a pill by Merck.
But experts caution that the coming surge will almost certainly tax hospitals again, especially in areas with lower vaccination rates.
And even states where blood testing shows that significant numbers of people have antibodies after a COVID-19 infection aren’t out of the woods, in part because we still don’t know how long the immunity generated by infection may last.
“Erosion of immunity”
“It’s hard to know how much risk is out there,” said Jeffrey Shaman, PhD, professor of environmental health sciences at Columbia University’s Mailman School of Public Health in New York City, who has been modeling the trajectory of the pandemic.
“We’re estimating, unfortunately, and we have for many weeks now, that there is an erosion of immunity,” Dr. Shaman said. “I think it could get bad. How bad? I’m not sure.”
Ali Mokdad, PhD, a professor of health metrics sciences at the University of Washington’s Institute for Health Metrics and Evaluation in Seattle, agrees.
Because there are so few studies on how long immunity from natural infection lasts, Dr. Mokdad and his colleagues are assuming that waning immunity after infection happens at least as quickly as it does after vaccination.
Their model is predicting that the average number of daily cases will peak at around 100,000, with another 100,000 going undetected, and will stay at that level until the end of January, as some states recover from their surges and others pick up steam.
While the number of daily deaths won’t climb to the heights seen during the summer surge, Dr. Mokdad said their model is predicting that daily deaths will climb again to about 1,200 a day.
“We are almost there right now, and it will be with us for a while,” he said. “We are predicting 881,000 deaths by March 1.”
The United States has currently recorded 773,000 COVID-19 deaths, so Dr. Mokdad is predicting about 120,000 more deaths between now and then.
He said his model shows that more than half of those deaths could be prevented if 95% of Americans wore their masks while in close proximity to strangers.
Currently, only about 36% of Americans are consistently wearing masks, according to surveys. While people are moving around more now, mobility is at prepandemic levels in some states.
“The rise that you are seeing right now is high mobility and low mask wearing in the United States,” Dr. Mokdad said.
The solution, he said, is for all adults to get another dose of vaccine — he doesn’t like calling it a booster.
“Because they’re vaccinated and they have two doses they have a false sense of security that they are protected. We needed to come ahead of it immediately and say you need a third dose, and we were late to do so,” Dr. Mokdad said.

Daily aspirin linked to increased risk of heart failure
Daily aspirin is associated with new onset heart failure independent of other risk factors, according to data derived from a database with follow-up from more than 30,000 patients who did not have HF when they were enrolled.
These data are not relevant to primary or secondary prevention of cardiovascular events but “refer only to starting aspirin for secondary prevention of HF in patients at high risk of HF or with symptomatic HF,” according to the senior investigator, Jan A. Staessen, MD, PhD, professor emeritus at the University of Leuven (Belgium).
In data from 30,827 patients at risk for HF enrolled in six observational studies, the hazard ratio (HR) for developing HF among those taking daily aspirin at baseline relative to those who were not was 1.26 (P ≤ .001) over 5.3 years of follow-up. In the 22,690 patients without a prior history cardiovascular disease (CVD), the HF risk increase for exposure to daily aspirin was about the same (HR 1.27; P = .001).
This study was launched because multiple conflicting studies have made the relationship between aspirin and HF risk unclear, according to the multinational team of authors, whose finding were published in ESC Heart Failure.
In principle, HF is recognized as a prothrombotic condition for which an antithrombotic therapy such as aspirin would be expected to have a protective role, but the investigators pointed out that the evidence is mixed. In a population-based Danish study of 12,277 patients with new-onset HF, for example, there was no relationship seen between aspirin use and a reduction in the composite outcome of all-cause mortality, myocardial infarction, or stroke.
Aspirin use linked to HF admissions
“Interestingly, this study reported that aspirin use was associated with an increased risk of readmissions for HF,” wrote the authors of the newly published data. “Uncertainty on aspirin use has been reflected in current guideline recommendations,” they added.
The population studied was drawn from the HOMAGE database, which has collated data on 46,437 participants in 21 studies. After the exclusion of studies with patients who already had HF as well as studies without information on HF incidence over time, six studies with 30,827 participants provided the basis for this analysis.
One study, ASCOT, which was randomized and blinded, served as the derivation data set. The remaining five studies, FLEMENGHO, HEALTH ABC, HULL LIFE LAB, PREDICTOR, and PROSPER, served as the validation data set.
In addition to identifying participants as aspirin users or nonusers at baseline, all of the studies had detailed baseline data on a wide variety of patient characteristics and risk factors, such as body mass index, blood cholesterol levels, blood glucose concentrations, blood pressure, and creatinine.
No patient in any trial was on an antithrombotic therapy other than aspirin at baseline.
Of the minority of patients with CVD at baseline, more than 80% had coronary heart disease. Only 2.8% of the total population had a prior myocardial infarction. In the study population overall, most (86%) had hypertension, and there was a sizeable proportion with diabetes (22%). The average age was 67 years, and 34% were women.
HF incidence on aspirin: 14.5/1000 person-years
Overall, the incidence rate of HF per 1,000 person-years for the entire population before adjustment was 14.5 in the group on daily aspirin versus 5.9 in the non-aspirin group. These absolute rates were lower in the discovery data set than in the validation set, but the relative differences in HF incidence rates for those who were versus those who were not on aspirin at baseline were similar.
Numerous sensitivity analyses supported the basic conclusions. This not only included one omitting patients with a history of CVD, but another that excluded patients who developed HF within the first 2 years. Stratified analyses looking for overall consistency across variables showed increased risk of new onset heart failure among those taking daily aspirin regardless of relative age, body weight, or blood pressure levels.
The most important limitation of this study was that it evaluated data taken from studies not originally designed to test the study hypothesis. In addition, only baseline data were available, so the drugs that patients took over the course of follow-up are unknown. However, the authors believe these data have a clinical message.
Given the consistency of these results, “our observations suggest that aspirin should be prescribed with caution in patients at risk of HF or having HF,” the investigators concluded.
“If such treatment is initiated in these patients, use low-dose aspirin,” Dr. Staessen told this news organization.
Aspirin for CVD versus HF risk
Many patients take low-dose aspirin to prevent the types of cardiovascular events, such as MI, that lead to heart failure. In attempting to address a controversy regarding aspirin and risk of new onset heart failure, it appears to create another regarding CVD risk reduction.
Deepak L. Bhatt, MD, executive director of Interventional Cardiovascular Programs at Brigham and Women’s Health, Boston, expressed some reluctance in applying these data to routine practice.
“It is important to emphasize that this pooled analysis draws upon six observational studies, not randomized trials of aspirin,” Dr. Bhatt said.
He called these findings “provocative,” but he said they “would need to be confirmed in databases of already completed randomized trials of aspirin versus a control before being actionable.” For Dr. Bhatt, one obstacle to a change in practice based on these data is that, “to my knowledge, no such signal [of a relationship between aspirin and incident heart failure] exists in the cumulative randomized data.”
Dr. Staessen reports no potential conflicts of interest for this study. Dr. Bhatt has a financial relationship with a large number of pharmaceutical companies, including PLx Pharma, for which he performs aspirin-related research.
Daily aspirin is associated with new onset heart failure independent of other risk factors, according to data derived from a database with follow-up from more than 30,000 patients who did not have HF when they were enrolled.
These data are not relevant to primary or secondary prevention of cardiovascular events but “refer only to starting aspirin for secondary prevention of HF in patients at high risk of HF or with symptomatic HF,” according to the senior investigator, Jan A. Staessen, MD, PhD, professor emeritus at the University of Leuven (Belgium).
In data from 30,827 patients at risk for HF enrolled in six observational studies, the hazard ratio (HR) for developing HF among those taking daily aspirin at baseline relative to those who were not was 1.26 (P ≤ .001) over 5.3 years of follow-up. In the 22,690 patients without a prior history cardiovascular disease (CVD), the HF risk increase for exposure to daily aspirin was about the same (HR 1.27; P = .001).

‘Misleading’ results in colchicine COVID-19 trials meta-analysis
A new meta-analysis appears to show that colchicine has no benefit as a treatment for COVID-19, but its inclusion of trials studying differing patient populations and testing different outcomes led to “misleading” results, says a researcher involved in one of the trials.
The meta-analysis, which includes data from the recent Randomised Evaluation of COVID-19 Therapy (RECOVERY) trial, was published Nov. 22 in RMD Open.
Kedar Gautambhai Mehta, MBBS, MD, of the GMERS Medical College Gotri in Vadodara, India, and colleagues included outcomes from six studies of 16,148 patients with COVID-19 who received colchicine or supportive care. They evaluated the efficacy outcomes of mortality, need for ventilation, intensive care unit admission, and length of stay in hospital, as well as safety outcomes of adverse events, serious adverse events, and diarrhea.
The studies in the meta-analysis included a randomized, controlled trial (RCT) of 105 patients hospitalized with COVID-19 in Greece, the international, open-label RECOVERY RCT of 11,340 patients hospitalized with COVID-19, an RCT of 72 hospitalized patients with moderate or severe COVID-19 in Brazil, an RCT of 100 patients hospitalized with COVID-19 in Iran, the international COLCORONA trial of 4,488 patients with COVID-19 who were treated with colchicine or placebo on an outpatient basis, and the randomized COLORIT trial of 43 patients hospitalized with COVID-19 in Russia.
Studies “asked very different questions” about colchicine
Commenting on the meta-analysis, Michael H. Pillinger, MD, a rheumatologist and professor of medicine, biochemistry, and molecular pharmacology with New York University, said the authors combined studies “that are not comparable and that asked very different questions.” Two of the studies in the meta-analysis are very large, and four are very small, which skews the results, he explained.
“The larger studies therefore drive the outcome, and while the small studies are potentially insight providing, the large studies are the only ones worth giving our attention to in the context of the meta-analysis,” he said. The two largest studies – RECOVERY and COLCORONA – taken together show no benefit for colchicine as a treatment, even though the former demonstrated no benefit and the latter did show a benefit, explained Dr. Pillinger, a co–principal investigator for the COLCORONA trial in the United States.
The studies were designed differently and should not have been included in the same analysis, Dr. Pillinger argued. In the case of COLCORONA, early treatment with colchicine was the intervention, whereas RECOVERY focused on hospitalized patients.
“In designing [COLCORONA], the author group (of whom I was a member) expressly rejected the idea that colchicine might be useful for the sicker hospitalized patients, based on the long experience with colchicine of some of us as rheumatologists,” Dr. Pillinger said.
“In short, COLCORONA proved a benefit of colchicine in outpatient COVID-19, and its authors presumed there would be no inpatient benefit; RECOVERY went ahead and proved a lack of inpatient benefit, at least when high-dose steroids were also given,” he said. “While there is no conflict between these results, the combination of the two studies in this meta-analysis suggests there might be no benefit for colchicine overall, which is misleading and can lead physicians to reject the potential of outpatient colchicine, even for future studies.”
Dr. Pillinger said he still believes colchicine has potential value as a COVID-19 treatment option for patients with mild disease, “especially for low–vaccine rate, resource-starved countries.
“It would be unfortunate if meta-analyses such as this one would put a stop to colchicine’s use, or at least its further investigation,” he said.
Study details
The authors of the study assessed heterogeneity of the trials’ data across the outcomes using an I2 test. They evaluated the quality of the evidence for the outcomes using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE).
The results of their meta-analysis showed that colchicine offered no significant improvement in mortality in six studies (risk difference, –0.0; 95% confidence interval, –0.01 to 0.01; I2 = 15%). It showed no benefit with respect to requiring ventilatory support in five studies of 15,519 patients (risk ratio, 0.67; 95% CI, 0.38-1.21; I2 = 47%); being admitted to the ICU in three studies with 220 patients (RR, 0.49; 95% CI, 0.19-1.25; I2 = 34%); and length of stay while in the hospital in four studies of 11,560 patients (mean difference, –1.17; 95% CI, –3.02 to 0.67; I2 = 77%).
There was no difference in serious adverse events in three studies with 4,665 patients (RD, –0.01; 95% CI, –0.02 to 0.00; I2 = 28%) for patients who received colchicine, compared with supportive care alone. Patients who received colchicine were more likely to have a higher rate of adverse events (RR, 1.58; 95% CI, 1.07-2.33; I2 = 81%) and to experience diarrhea (RR, 1.93; 95% CI, 1.62-2.29; I2 = 0%) than were patients who received supportive care alone. The researchers note that for most outcomes, the GRADE quality of evidence was moderate.
“Our findings on colchicine should be interpreted cautiously due to the inclusion of open-labeled, randomized clinical trials,” Dr. Mehta and colleagues write. “The analysis of efficacy and safety outcomes are based on a small number of RCTs in control interventions.”
The authors reported no relevant financial relationships. Dr. Pillinger is co–principal investigator of the U.S. component of the COLCORONA trial; he reported no other relevant conflicts of interest.

Predicting cardiac shock mortality in the ICU
Addition of echocardiogram measurement of biventricular dysfunction improved the accuracy of prognosis among patients with cardiac shock (CS) in the cardiac intensive care unit.
In patients in the cardiac ICU with CS, biventricular dysfunction (BVD), as assessed using transthoracic echocardiography, improves clinical risk stratification when combined with the Society for Cardiovascular Angiography and Interventions shock stage.
No improvements in risk stratification was seen with patients with left or right ventricular systolic dysfunction (LVSD or RVSD) alone, according to an article published in the journal Chest.
Ventricular systolic dysfunction is commonly seen in patients who have suffered cardiac shock, most often on the left side. Although echocardiography is often performed on these patients during diagnosis, previous studies looking at ventricular dysfunction used invasive hemodynamic parameters, which made it challenging to incorporate their findings into general cardiac ICU practice.

Although treatment of acute MI and heart failure has improved greatly, particularly with the implementation of percutaneous coronary intervention (primary PCI) for ST-segment elevation MI. This has reduced the rate of future heart failure, but cardiac shock can occur before or after the procedure, with a 30-day mortality of 30%-40%. This outcome hasn’t improved in the last 20 years.
Efforts to improve cardiac shock outcomes through percutaneous mechanical circulatory support devices have been hindered by the fact that CS patients are heterogeneous, and prognosis may depend on a range of factors.
SCAI was developed as a five-stage classification system for CS to improve communication of patient status, as well as to improve differentiation among patients participation in clinical trials. It does not include measures of ventricular dysfunction.
Simple measure boosts prognosis accuracy
The new work adds an additional layer to the SCAI shock stage. “Adding echocardiography allows discrimination between levels of risk for each SCAI stage,” said David Baran, MD, who was asked for comment. Dr. Baran was the lead author on the original SCAI study and is system director of advanced heart failure at Sentara Heart Hospital, as well as a professor of medicine at Eastern Virginia Medical School, both in Norfolk.
The work also underscores the value of repeated measures of prognosis during a patient’s stay in the ICU. “If a patient is not improving, it may prompt a consideration of whether transfer or consultation with a tertiary center may be of value. Conversely, if a patient doesn’t have high-risk features and is responding to therapy, it is reassuring to have data supporting low mortality with that care plan,” said Dr. Baran.
The study may be biased, since not every patient undergoes an echocardiogram. Still, “the authors make a convincing case that biventricular dysfunction is a powerful negative marker across the spectrum of SCAI stages,” said Dr. Baran.
Echocardiography is simple and generally available, and some are even portable and used with a smartphone. But patient body size interferes with echocardiography, as can the presence of a ventilator or multiple surgical dressings. “The key advantage of echo is that it is completely noninvasive and can be brought to the patient in the ICU, unlike other testing which involves moving the patient to the testing environment,” said Dr. Baran.
The researchers analyzed data from 3,158 patients admitted to the cardiac ICU at the Mayo Clinic Hospital St. Mary’s Campus in Rochester, Minn., 51.8% of whom had acute coronary syndromes. They defined LVSD as a left ventricular ejection fraction less than 40%, and RVSD as at least moderate systolic dysfunction determined by semiquantitative measurement. BVD constituted the presence of both LVSD and RVSD. They examined the association of in-hospital mortality with these parameters combined with SCAI stage.
BVD a risk factor
Overall in-hospital mortality was 10%. A total of 22.3% of patients had LVSD and 11.8% had RVSD; 16.4% had moderate or greater BVD. There was no association between LVSD or RVSD and in-hospital mortality after adjustment for SCAI stage, but there was a significant association for BVD (adjusted hazard ratio, 1.815; P = .0023). When combined with SCAI, BVC led to an improved ability to predict hospital mortality (area under the curve, 0.784 vs. 0.766; P < .001). Adding semiquantitative RVSD and LVSD led to more improvement (AUC, 0.794; P < .01 vs. both).
RVSD was associated with higher in-hospital mortality (adjusted odds ratio, 1.421; P = .02), and there was a trend toward greater mortality with LVSD (aOR, 1.336; P = .06). There was little change when SCAI shock stage A patients were excluded (aOR, 1.840; P < .001).
Patients with BVD had greater in-hospital mortality than those without ventricular dysfunction (aOR, 1.815; P = .0023), but other between-group comparisons were not significant.
The researchers performed a classification and regression tree analysis using left ventricular ejection fraction (LVEF) and semiquantitative RVSD. It found that RVSD was a better predictor of in-hospital mortality than LVSD, and the best cutoff for LVSD was different among patients with RVSD and patients without RVSD.
Patients with mild or greater RVD and LVEF greater than 24% were considered high risk; those with borderline or low RVSD and LVEF less than 33%, or mild or greater RVSD with LVEF of at least 24%, were considered intermediate risk. Patients with borderline or no RVSD and LVEF of at least 33% were considered low risk. Hospital mortality was 22% in the high-risk group, 12.2% in the intermediate group, and 3.3% in the low-risk group (aOR vs. intermediate, 0.493; P = .0006; aOR vs. high risk, 0.357; P < .0001).
The study authors disclosed no relevant financial relationships.

Addition of echocardiogram measurement of biventricular dysfunction improved the accuracy of prognosis among patients with cardiac shock (CS) in the cardiac intensive care unit.
In patients in the cardiac ICU with CS, biventricular dysfunction (BVD), as assessed using transthoracic echocardiography, improves clinical risk stratification when combined with the Society for Cardiovascular Angiography and Interventions shock stage.
No improvements in risk stratification was seen with patients with left or right ventricular systolic dysfunction (LVSD or RVSD) alone, according to an article published in the journal Chest.
Ventricular systolic dysfunction is commonly seen in patients who have suffered cardiac shock, most often on the left side.

Penicillin slows latent rheumatic heart disease progression
In a randomized controlled trial of close to 1,000 Ugandan children and youth with latent rheumatic heart disease (RHD), those who received monthly injections of penicillin G benzathine for 2 years had less disease progression than those who did not.
RHD, a valvular heart disease caused by rheumatic fever that develops after untreated Streptococcus pyogenes infection, is the most common acquired cardiovascular disease among children and young adults.
“It is clear that secondary antibiotic prophylaxis can improve outcomes for children with echo-detected rheumatic RHD,” co–lead author of the study, Andrea Z. Beaton, MD, said in an interview.
“There is huge potential here, but we are not quite ready to advocate for this strategy as a broad public health approach,” said Dr. Beaton, a pediatric cardiologist at Cincinnati Children’s Hospital Medical Center.
“We need to understand more the practical translation of this strategy to a low-resourced public health system at scale, improve [penicillin G benzathine] supply, and improve community and health care worker knowledge of this disease.”
Dr. Beaton presented the findings at the American Heart Association scientific sessions, and the study was simultaneously published in the New England Journal of Medicine on Nov. 13, 2021.
The GOAL trial – or the Gwoko Adunu pa Lutino trial, meaning “protect the heart of a child” – screened 102,200 children and adolescents aged 5-17. Of these kids and teenagers, 926 (0.9%) were diagnosed with latent RHD based on a confirmatory electrocardiogram.
“For now, I would say, if you are screening, then kids found to have latent RHD should be put on prophylaxis,” Dr. Beaton said.
“I think this is also a powerful call for more research [severely lacking in RHD],” to improve risk stratification, determine how to implement screening and prophylaxis programs, and develop new and better approaches for RHD prevention and care.
“This essential trial partially addresses the clinical equipoise that has developed regarding penicillin administration in latent RHD,” said Gabriele Rossi, MD, MPH, who was not involved with this research.
It showed that, out of the final 818 participants included in the modified intention-to-treat analysis, a total of 3 (0.8%) in the prophylaxis group had echocardiographic progression at 2 years, compared with 33 participants (8.2%) in the control group (risk difference, −7.5 percentage points; 95% confidence interval, −10.2 to −4.7; P < .001).
“This is a significant difference,” Dr. Rossi, from Médecins Sans Frontières (Doctors Without Borders), Brussels, said in an interview, noting that, however, it is not known what happens after 2 years.
The authors estimated that 13 children or adolescents with latent rheumatic heart disease would need to be treated to prevent disease progression in one person at 2 years, which is “acceptable,” he continued.
However, “screening, diagnosis, clinical follow-up, treatment, and program management [would] require substantial strengthening of health systems and the workforce, which is still far from being realizable in many African and low-income country settings,” Dr. Rossi noted.
Related study in Italy
Previously, Dr. Rossi and colleagues conducted a trial, published in 2019, that showed it was feasible to screen for asymptomatic RHD among refugee/migrant children and youths in Rome.
From February 2016 to January 2018, they screened more than 650 refugee/migrant children and adolescents who were younger than 18. They came largely from Egypt (65%) but also from 22 other countries and were often unaccompanied or with just one parent.
The number needed to screen was 5 to identify a child/youth with borderline RHD and around 40 to identify a child/youth with definite RHD.
Dr. Rossi noted that local resurgences of RHD have also been also documented in high-income countries such as Europe, Australia, New Zealand, Canada, and the United States, often among disadvantaged indigenous people, as described in a 2018 Letter to the Editor in the New England Journal of Medicine.
Dr. Beaton noted that a review of 10-year data (2008-2018) from 22 U.S. pediatric institutions showed that in the United States the prevalence of RHD “is higher in immigrant children from RHD endemic areas, but because of total numbers, more RHD cases than not are domestic.” Children living in more deprived communities are at risk for more severe disease, and the burden in U.S. territories is also quite high.
Screening and secondary prophylaxis
The aim of the current GOAL study was to evaluate if screening and treatment with penicillin G benzathine could detect and prevent progression of latent rheumatic heart disease in 5- to 17-year-olds living in Gulu, Uganda. The trial was conducted from July 2018 to October 2020.
“School education and community sensitization was done prior to the trial,” through radio shows or school-based education, Dr. Beaton explained. About 99% of the children/adolescents/families agreed to be screened.
The group has been conducting echo screening research in Uganda for 10 years, she noted. They have developed peer group and case manager strategies to aid participant retention, as they describe in an article about the study protocol.
The screening echocardiograms were interpreted by about 30 providers and four cardiologists reviewed confirmatory echocardiograms.
Two participants in the prophylaxis group had serious adverse events that were attributable to receipt of prophylaxis, including one episode of a mild anaphylactic reaction (representing <0.1% of all administered doses of prophylaxis).
Once children and adolescents have moderate/severe RHD, there is not much that can be done in lower- and middle-income countries, where surgery for this is uncommon, Dr. Beaton explained. Around 30% of children and adolescents with this condition who come to clinical attention in Uganda die within 9 months.
Further research
Dr. Beaton and colleagues have just started a trial to investigate the burden of RHD among Native American youth, which has not been studied since the 1970s.
They also have an ongoing study looking at the efficacy of a pragmatic, community-based sore throat program to prevent RHD.
“Unfortunately, this strategy has not worked well in low-to-middle income countries, for a variety of reasons so far,” Dr. Beaton noted, and the cost-effectiveness of this preventive strategy is questionable.
The trial was supported by the Thrasher Research Fund, Gift of Life International, Children’s National Hospital Foundation (Zachary Blumenfeld Fund and Race for Every Child [Team Jocelyn]), the Elias-Ginsburg Family, Wiley Rein, Philips Foundation, AT&T Foundation, Heart Healers International, the Karp Family Foundation, Huron Philanthropies, and the Cincinnati Children’s Hospital Heart Institute Research Core.

Dr. Beaton noted that a review of 10-year data (2008-2018) from 22 U.S. pediatric institutions showed that in the United States the prevalence of RHD “is higher in immigrant children from RHD endemic areas, but because of total numbers, more RHD cases than not are domestic.” Children living in more deprived communities are at risk for more severe disease, and the burden in U.S. territories is also quite high.
Screening and secondary prophylaxis
The aim of the current GOAL study was to evaluate if screening and treatment with penicillin G benzathine could detect and prevent progression of latent rheumatic heart disease in 5- to 17-year-olds living in Gulu, Uganda. The trial was conducted from July 2018 to October 2020.
“School education and community sensitization was done prior to the trial,” through radio shows or school-based education, Dr. Beaton explained. About 99% of the children/adolescents/families agreed to be screened.
The group has been conducting echo screening research in Uganda for 10 years, she noted. They have developed peer group and case manager strategies to aid participant retention, as they describe in an article about the study protocol.
The screening echocardiograms were interpreted by about 30 providers and four cardiologists reviewed confirmatory echocardiograms.
Two participants in the prophylaxis group had serious adverse events that were attributable to receipt of prophylaxis, including one episode of a mild anaphylactic reaction (representing <0.1% of all administered doses of prophylaxis).
Once children and adolescents have moderate/severe RHD, there is not much that can be done in lower- and middle-income countries, where surgery for this is uncommon, Dr. Beaton explained. Around 30% of children and adolescents with this condition who come to clinical attention in Uganda die within 9 months.
Further research
Dr. Beaton and colleagues have just started a trial to investigate the burden of RHD among Native American youth, which has not been studied since the 1970s.
They also have an ongoing study looking at the efficacy of a pragmatic, community-based sore throat program to prevent RHD.
“Unfortunately, this strategy has not worked well in low-to-middle income countries, for a variety of reasons so far,” Dr. Beaton noted, and the cost-effectiveness of this preventive strategy is questionable.
The trial was supported by the Thrasher Research Fund, Gift of Life International, Children’s National Hospital Foundation (Zachary Blumenfeld Fund and Race for Every Child [Team Jocelyn]), the Elias-Ginsburg Family, Wiley Rein, Philips Foundation, AT&T Foundation, Heart Healers International, the Karp Family Foundation, Huron Philanthropies, and the Cincinnati Children’s Hospital Heart Institute Research Core. Dr. Beaton and Dr. Rossi disclosed no relevant financial relationships.
