Ivermectin doesn’t help treat COVID-19, large study finds
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.

Fingers take the fight to COVID-19
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.
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.
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.
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.
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.

Obesity increasing the risk for cancer: It’s complicated
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.
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.
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.”

Avocados linked to lower cardiovascular risk
A prospective study that followed more than 110,000 men and women for more than 30 years suggests that .
Researchers also found that replacing half a serving of butter, cheese, bacon, or other animal product with an equivalent amount of avocado was associated with up to 22% lower risk for CVD events.
The findings add to evidence from other studies that has shown that avocados – which contain multiple nutrients, including fiber and unsaturated, healthy fats – have a positive impact on cardiovascular risk factors, first author Lorena S. Pacheco, PhD, a postdoctoral research fellow at the Harvard T.H. Chan School of Public Health, Boston, said in an interview.
“This research complements and expands on the current literature that we have on unsaturated fats and reduced risk of cardiovascular disease and also underscores how bad saturated fats, like butter, cheese, and processed meats are for the heart,” Dr. Pacheco said.
“For the most part, we have known that avocados are healthy, but I think this study, because of its numbers and duration, adds a little more substance to that knowledge now,” Dr. Pacheco said.
The findings were published online March 30 in the Journal of the American Heart Association.
Avocados are dense with nutrients. They are high in fat, but in monounsaturated fats (MUFAs) and polyunsaturated fats (PUFAs), which are viewed as good.
A medium-sized (136 g) Haas avocado, which is the most commonly consumed avocado in the United States, contains roughly 13 g of oleic acid. Avocados also contain dietary fiber, potassium, magnesium, phytonutrients, and bioactive compounds.
To see the effect avocados can have on cardiovascular health, Dr. Pacheco and her team turned to two large, long-running cohort studies: the Nurses’ Health Study (NHS), which began in the early 1970s with 68,786 women 30-55 years of age; and the Health Professionals Follow-up Study (HPFS), which ran from 1986 to 2016 and followed 41,701 men 40-75 years of age.
All were free of cancer, coronary heart disease, and stroke at study entry.
Participants completed a validated food frequency questionnaire at baseline and every 4 years thereafter. The questionnaire asked about the amount and frequency of avocado consumed. One serving equaled half an avocado, or half a cup.
In the early days of the NHS, very few participants said they ate avocados, but that began to change over the years, as the popularity of avocados grew.
“The NHS cohort was recruited back in the late ‘70s, and the health professionals cohort did not start until the mid 1980s, when avocado consumption was really low,” Dr. Pacheco said.
“What is beautiful about these cohorts is we are able to ask participants questions and then save the answers that they give us throughout the years to answer questions that might arise whenever the question is right. So it just depends on when you accrue enough data to ask those questions about potential cardiovascular benefit with avocados,” she said.
There were 9,185 coronary heart disease events and 5,290 strokes documented over 30 years of follow-up.
After adjustment for lifestyle and other dietary factors, those with a higher avocado intake – at least two servings per week – had a 16% lower risk for CVD (pooled hazard ratio, 0.84; 95% CI, 0.75-0.95) and a 21% lower risk for coronary heart disease (pooled HR, 0.79; 95% CI, 0.68-0.91).
No significant associations were seen for stroke, but this is because the study did not have sufficient numbers, Dr. Pacheco explained.
A statistical model also determined that replacing half a serving daily of margarine, butter, egg, yogurt, cheese, or processed meats, such as bacon, with the same amount of avocado was associated with a 16%-22% lower risk for CVD events.
“I want to emphasize that the study is an epidemiological observational study and cannot prove cause and effect,” Dr. Pacheco said.
“It’s not a clinical trial – it’s based on observational epidemiology – but we saw patterns in the model: Avocado consumption and substituting avocado for other unhealthy fats reduced the risk of having a cardiovascular event or coronary heart disease,” she said.
The findings are significant “because a healthy dietary pattern is the cornerstone for cardiovascular health; however, it can be difficult for many Americans to achieve and adhere to healthy eating patterns,” Cheryl Anderson, PhD, professor and dean of the Herbert Wertheim School of Public Health and Human Longevity Science at the University of California, San Diego, who is chair of the AHA’s Council on Epidemiology and Prevention, said in a statement.
“We desperately need strategies to improve intake of AHA-recommended healthy diets, such as the Mediterranean diet, that are rich in vegetables and fruits. Although no one food is the solution to routinely eating a healthy diet, this study is evidence that avocados have possible health benefits. This is promising because it is a food item that is popular, accessible, desirable, and easy to include in meals eaten by many Americans at home and in restaurants,” said Dr. Anderson, who was not part of the study.
Dr. Pacheco and Dr. Anderson report no relevant financial relationships.

Pneumococcal pneumonia outcomes worse than those of Legionnaires disease
Outcomes for patients with bacteremic Streptococcus pneumoniae were significantly worse than those for patients with Legionnaires disease (LD), based on data from 106 individuals.
Reported cases of LD in the United States have increased in recent decades, but they are likely under-reported, wrote Sima Salahie, MD, of Wayne State University School of Medicine, Detroit, and Central Michigan University College of Medicine, Grosse Pointe Woods, and colleagues.
Clinical presentations may be similar for both conditions, but different antimicrobial therapies are needed; therefore, identifying distinguishing factors can promote better management of hospitalized patients, they reported.
In a retrospective case companion study published in the American Journal of the Medical Sciences, the researchers reviewed data from 51 adults with LD and 55 with bacteremic S. pneumoniae pneumonia (SP) who were hospitalized at a single center between 2013 and 2018. Diagnoses were confirmed by laboratory and radiology results. In addition, data were collected on clinical features including body mass index, systolic and diastolic blood pressure, pulse, respiratory rate, and temperature.
Overall, patients with SP were significantly more likely than those with LD to require mechanical ventilation (P = .04), intensive care unit stay (P = .004), and to die (P = .002). Patients with SP also had higher rates of septic shock compared to LD patients, although this difference fell short of statistical significance (49.1% vs. 30.4%; P = .06).
In a multivariate analysis, male sex, diarrhea, higher body mass index, hyponatremia, and lower Charleston Weighted Index of Comorbidity (CWIC) score were significant independent predictors of LD, with odds ratios of 21.6, 4.5, 1.13, 5.6, and 0.61, respectively.
The incidence of LD peaked in summer, while the incidence of SP peaked in the winter, the researchers noted. “Seasonality is a variable that has not always been included in previous scoring systems but should be considered in future modeling,” they said.
“Noteworthy is that LD represented almost as many cases as documented bacteremic pneumococcal pneumonia,” the researchers wrote in their discussion. “This occurred at a time when there was no outbreak of L. pneumophila in our community, and as these were all community acquired, there was no evidence of a nosocomial outbreak in our institution,” they said.
The study findings were limited by several factors, including the possible underestimation of SP because of the requirement for positive blood cultures and the lack of other methods of diagnosing SP, the researchers noted.
“However, the data suggest variables to distinguish LD from SP,” they said. “Establishing reliable clinical and laboratory parameters embedded in a simple diagnostic score that can accurately identify patients with LD may be helpful in aiding physicians’ early diagnosis in distinguishing LD from SP but will need to be defined.”
The study received no outside funding. The researchers disclosed no financial conflicts.

Clinical presentations may be similar for both conditions, but different antimicrobial therapies are needed; therefore, identifying distinguishing factors can promote better management of hospitalized patients, they reported.
In a retrospective case companion study published in the American Journal of the Medical Sciences, the researchers reviewed data from 51 adults with LD and 55 with bacteremic S. pneumoniae pneumonia (SP) who were hospitalized at a single center between 2013 and 2018. Diagnoses were confirmed by laboratory and radiology results. In addition, data were collected on clinical features including body mass index, systolic and diastolic blood pressure, pulse, respiratory rate, and temperature.
Overall, patients with SP were significantly more likely than those with LD to require mechanical ventilation (P = .04), intensive care unit stay (P = .004), and to die (P = .002). Patients with SP also had higher rates of septic shock compared to LD patients, although this difference fell short of statistical significance (49.1% vs. 30.4%; P = .06).
In a multivariate analysis, male sex, diarrhea, higher body mass index, hyponatremia, and lower Charleston Weighted Index of Comorbidity (CWIC) score were significant independent predictors of LD, with odds ratios of 21.6, 4.5, 1.13, 5.6, and 0.61, respectively.
The incidence of LD peaked in summer, while the incidence of SP peaked in the winter, the researchers noted. “Seasonality is a variable that has not always been included in previous scoring systems but should be considered in future modeling,” they said.
“Noteworthy is that LD represented almost as many cases as documented bacteremic pneumococcal pneumonia,” the researchers wrote in their discussion. “This occurred at a time when there was no outbreak of L. pneumophila in our community, and as these were all community acquired, there was no evidence of a nosocomial outbreak in our institution,” they said.
The study findings were limited by several factors, including the possible underestimation of SP because of the requirement for positive blood cultures and the lack of other methods of diagnosing SP, the researchers noted.
“However, the data suggest variables to distinguish LD from SP,” they said. “Establishing reliable clinical and laboratory parameters embedded in a simple diagnostic score that can accurately identify patients with LD may be helpful in aiding physicians’ early diagnosis in distinguishing LD from SP but will need to be defined.”
The study received no outside funding. The researchers disclosed no financial conflicts.

Does evidence support benefits of omega-3 fatty acids?
Dietary supplements that contain omega-3 fatty acids have been widely consumed for years. Researchers have been investigating the benefits of such preparations for cardiovascular, neurologic, and psychological conditions. A recently published study on omega-3 fatty acids and depression inspired neurologist Hans-Christoph Diener, MD, PhD, of the Institute for Epidemiology at the University Duisburg-Essen (Germany), to examine scientific publications concerning omega-3 fatty acids or fish-oil capsules in more detail.
Prevention of depression
Dr. Diener told the story of how he stumbled upon an interesting article in JAMA in December 2021. It was about a placebo-controlled study that investigated whether omega-3 fatty acids can prevent incident depression.
As the study authors reported, treatment with omega-3 preparations in adults aged 50 years or older without clinically relevant symptoms of depression at study initiation was associated with a small but statistically significant increase in the risk for depression or clinically relevant symptoms of depression. There was no difference in mood scale value, however, over a median follow-up of 5.3 years. According to the study authors, these results did not support the administration of omega-3 preparations for the prevention of depression.
This study was, as Dr. Diener said, somewhat negative, but it did arouse his interest in questions such as what biological effects omega-3 fatty acids have and what is known “about this topic with regard to neurology,” he said. When reviewing the literature, he noticed that there “were association studies, i.e., studies that describe that the intake of omega-3 fatty acids may possibly be associated with a lower risk of certain diseases.”
Beginning with the Inuit
It all started “with observations of the Inuit [population] in Greenland and Alaska after World War II, because it was remarked upon that these people ate a lot of fish and seal meat and had a very low incidence of cardiovascular diseases.” Over the years, a large number of association studies have been published, which may have encouraged the assumption that omega-3 fatty acids have positive health effects on various conditions, such as cardiovascular diseases, hyperlipidemia, type 2 diabetes, various malignancies, cognitive impairments, Alzheimer’s disease, depression and anxiety disorders, heart failure, slipped disks, ADHD, symptoms of menopause, rheumatoid arthritis, asthma, periodontitis, epilepsy, chemotherapy tolerance, premenstrual syndrome, and nonalcoholic fatty liver disease.
Dr. Diener believes that the problem is that these are association studies. But association does not mean that there is a causal relationship.
Disappointing study results
On the contrary, the results from the randomized placebo-controlled studies are truly frustrating, according to the neurologist. A meta-analysis of the use of omega-3 fatty acids in cardiovascular diseases included 86 studies with over 162,000 patients. According to Dr. Diener, it did not reveal any benefit for overall and cardiovascular mortality, nor any benefit for the reduction of myocardial infarction and stroke.
The results did indicate a trend, however, for reduced mortality in coronary heart disease. Even so, the number needed to treat for this was 334, which means that 334 people would have to take omega-3 fatty acids for years to prevent one fatal cardiac event.
Aside from this study, Dr. Diener found six studies on Alzheimer’s disease and three studies on dementia with patient populations between 600 and 800. In these studies, too, a positive effect of omega-3 fatty acids could not be identified. Then he discovered another 31 placebo-controlled studies of omega-3 fatty acids for the treatment or prevention of depression and anxiety disorder. Despite including 50,000 patients, these studies also did not show any positive effect.
“I see a significant discrepancy between the promotion of omega-3 fatty acids, whether it’s on television, in the ‘yellow’ [journalism] press, or in advertisements, and the actual scientific evidence,” said Dr. Diener. “At least from a neurological perspective, there is no evidence that omega-3 fatty acids have any benefit. This is true for strokes, dementia, Alzheimer’s disease, depression, and anxiety disorders.”
Potential adverse effects
Omega-3 fatty acids also have potentially adverse effects. The VITAL Rhythm study recently provided evidence that, depending on the dose, preparations with omega-3 fatty acids may increase the risk for atrial fibrillation. As the authors wrote, the results do not support taking omega-3 fatty acids to prevent atrial fibrillation.
In 2019, the global market for omega-3 fatty acids reached a value of $4.1 billion. This value is expected to double by 2025, according to a comment by Gregory Curfman, MD, deputy editor of JAMA and lecturer in health care policy at Harvard Medical School, Boston.
As Dr. Curfman wrote, this impressive amount of expenditure shows how beloved these products are and how strongly many people believe that omega-3 fatty acids are beneficial for their health. It is therefore important to know the potential risks of such preparations. One such example for this would be the risk for atrial fibrillation.
According to Dr. Curfman, in the last 2 years, four randomized clinical studies have provided data on the risk for atrial fibrillation associated with omega-3 fatty acids. In the STRENGTH study, 13,078 high-risk patients with cardiovascular diseases were randomly assigned to one of two groups. The subjects received either a high dose (4 g/day) of a combination of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) or corn oil. After a median of 42 months, there was no significant difference between the two groups in the primary composite cardiovascular endpoint, but more frequent atrial fibrillation in the omega-3 fatty acid group, compared with the corn oil group (2.2% vs. 1.3%; hazard ratio, 1.69; 95% confidence interval, 1.29-2.21; P < .001).
In the REDUCE-IT study, 8179 subjects were randomly assigned to a high dose (4 g/day, as in STRENGTH) of an omega-3 fatty acid preparation consisting of a purified EPA (icosapent ethyl) or mineral oil. After a median observation period of 4.9 years, icosapent ethyl was associated with a relative reduction of the primary composite cardiovascular endpoint by 25%, compared with mineral oil. As in the STRENGTH study, this study found that the risk for atrial fibrillation associated with omega-3 fatty acids, compared with mineral oil, was significantly higher (5.3% vs. 3.9%; P = .003).
In a third study (OMEMI), as Dr. Curfman reported, 1027 elderly patients who had recently had a myocardial infarction were randomly assigned to receive either a median dose of 1.8 g/day of omega-3 fatty acids (a combination of EPA and DHA) or corn oil. After 2 years, there was no significant difference between the two groups in primary composite cardiovascular endpoints, but 7.2% of the patients taking omega-3 fatty acids developed atrial fibrillation. In the corn oil group, this proportion was 4% (HR, 1.84; 95% CI, 0.98-3.45; P = .06).
The data from the four studies together indicate a potential dose-dependent risk for atrial fibrillation associated with omega-3 fatty acids, according to Dr. Curfman. At a dose of 4.0 g/day, there is a highly significant risk increase (almost double). With a median dose of 1.8 g/day, the risk increase (HR, 1.84) did not reach statistical significance. At a daily standard dose of 840 mg/day, an increase in risk could not be determined.
Dr. Curfman’s recommendation is that patients who take, or want to take, preparations with omega-3 fatty acids be informed of the potential development of arrhythmia at higher dosages. These patients also should undergo cardiological monitoring.

You’re not on a ‘best doctor’ list – does it matter?
Thousands of doctors get a shout out every year when they make the “Top Doctor” lists in various magazines. Some may be your colleagues or competitors. Should you be concerned if you’re not on the list?
Best Doctor lists are clearly popular with readers and make money for the magazines. They can also bring in patient revenue for doctors and their employers who promote them in news releases and on their websites.
For doctors on some of the top lists, the recognition can bring not only patients, but national or international visibility.
While the dollar value is hard to come by, some doctors say that these lists have attracted new patients to their practice.
Sarah St. Louis, MD, a physician manager of Associates in Urogynecology, is one of Orlando Style magazine’s Doctors of the Year and Orlando Family Magazine’s Top Doctors.
Several new patients have told her that they read about her in the magazines’ Top Doctor lists. “Urogynecology is not a well-known specialty – it’s a helpful way to get the word out about the women’s health specialty and what I do,” said Dr. St. Louis, an early career physician who started her practice in 2017.
The additional patient revenue has been worth the cost of displaying her profile in Orlando Style, which was about $800 for a half-page spread with her photo.
Top Doctor lists also work well for specialty practices whose patients can self-refer, such as plastic surgery, dermatology, orthopedics, gastroenterology, and geriatric medicine, said Andrea Eliscu, RN, founder and president of Medical Marketing in Orlando.
Being in a competitive market also matters. If a practice is the only one in town, those doctors may not need the publicity as much as doctors in an urban practice that faces stiff competition.
How do doctors get on these lists?
In most cases, doctors have to be nominated by their peers, a process that some say is flawed because it may shut out doctors who are less popular or well-connected.
Forty-eight regional magazines, including Chicago magazine and Philadelphia Magazine , partner with Castle Connolly to use their online Top Doctor database of more than 61,000 physicians in every major metropolitan area, said Steve Leibforth, managing director of Castle Connolly’s Top Doctors.
The company says it sends annual surveys to tens of thousands of practicing doctors asking them to nominate colleagues in their specialty. The nominated doctors are vetted by Castle Connolly’s physician-led research team on several criteria including professional qualifications, education, hospital and faculty appointments, research leadership, professional reputation and disciplinary history, and outcomes data when available, said Mr. Leibforth.
Washingtonian magazine says it sends annual online surveys to 13,500 physicians in the DC metro area asking them to nominate one colleague in their specialty. The top vote-getters in each of 39 categories are designated Top Doctors.
Orlando Family Magazine says its annual Top Doctor selections are based on reader polls and doctor nominations.
Consumers’ Research Council of America uses a point system based on each year the doctor has been in practice, education and continuing education, board certification, and membership in professional medical societies.
Doctors have many ways to promote that they’re listed as a “top” doctor. Dr. St. Louis takes advantage of the magazine’s free reprints, which she puts in her waiting room.
Others buy plaques to hang up in their waiting rooms or offices and announce the distinction on their websites, blogs, or social media. “They have to maximize the magazine distinction or it’s worthless,” said Ms. Eliscu.
Employers also like to spread the word when their doctors make it on “Top Doctor” lists.
“With Emory physicians making up nearly 50 percent of the list, that’s more than any other health system in Atlanta,” said an Emory University press release after nearly half of the university’s doctors made the Top Doctors list in Atlanta magazine.
Patients may be impressed: What about your peers?
Dr. St. Louis said that making some of these lists is less impressive than having a peer-reviewed journal article or receiving professional awards.
“Just because a physician is listed in a magazine as a ‘top doctor’ does not mean they are the best. There are far more medical, clinical, and scientific points to consider than just a pretty picture in a style magazine,” she said.
Wanda Filer, MD, MBA, who practiced family medicine until last year when she became chief medical officer for VaxCare in Orlando, said she ignores the many congratulatory letters in the mail announcing that she’s made one list or another.
“I don’t put much credence in the lists. I get notifications fairly often, and to me it always looks like they’re trying to sell a plaque. I’d rather let my work speak for itself.”
Arlen Meyers, MD, MBA, president and CEO of the Society of Physician Entrepreneurs and a paid strategic adviser to RYTE, a data-driven site for “best doctors” and “best hospitals,” said he received several of these “top doctor” awards when he was a professor of otolaryngology at the University of Colorado.
He has been critical of these awards for some time. “These doctor beauty pageants may be good for business but have little value for patients.”
He would like to see a new approach that is driven by data and what patients value. “If I have a lump in my thyroid, I want to know the best doctor to treat me based on outcomes data.”
He said a good rating system would include a data-driven approach based on treatment outcomes, publicly available data, price transparency, and patient values.
Whether a physician feels honored to be named a top physician or sees little value in it, most doctors are aware of the list’s marketing value for their practices and many choose to make use of it.

Several new patients have told her that they read about her in the magazines’ Top Doctor lists. “Urogynecology is not a well-known specialty – it’s a helpful way to get the word out about the women’s health specialty and what I do,” said Dr. St. Louis, an early career physician who started her practice in 2017.
The additional patient revenue has been worth the cost of displaying her profile in Orlando Style, which was about $800 for a half-page spread with her photo.
Top Doctor lists also work well for specialty practices whose patients can self-refer, such as plastic surgery, dermatology, orthopedics, gastroenterology, and geriatric medicine, said Andrea Eliscu, RN, founder and president of Medical Marketing in Orlando.
Being in a competitive market also matters. If a practice is the only one in town, those doctors may not need the publicity as much as doctors in an urban practice that faces stiff competition.
How do doctors get on these lists?
In most cases, doctors have to be nominated by their peers, a process that some say is flawed because it may shut out doctors who are less popular or well-connected.
Forty-eight regional magazines, including Chicago magazine and Philadelphia Magazine , partner with Castle Connolly to use their online Top Doctor database of more than 61,000 physicians in every major metropolitan area, said Steve Leibforth, managing director of Castle Connolly’s Top Doctors.
The company says it sends annual surveys to tens of thousands of practicing doctors asking them to nominate colleagues in their specialty. The nominated doctors are vetted by Castle Connolly’s physician-led research team on several criteria including professional qualifications, education, hospital and faculty appointments, research leadership, professional reputation and disciplinary history, and outcomes data when available, said Mr. Leibforth.
Washingtonian magazine says it sends annual online surveys to 13,500 physicians in the DC metro area asking them to nominate one colleague in their specialty. The top vote-getters in each of 39 categories are designated Top Doctors.
Orlando Family Magazine says its annual Top Doctor selections are based on reader polls and doctor nominations.
Consumers’ Research Council of America uses a point system based on each year the doctor has been in practice, education and continuing education, board certification, and membership in professional medical societies.
Doctors have many ways to promote that they’re listed as a “top” doctor. Dr. St. Louis takes advantage of the magazine’s free reprints, which she puts in her waiting room.
Others buy plaques to hang up in their waiting rooms or offices and announce the distinction on their websites, blogs, or social media. “They have to maximize the magazine distinction or it’s worthless,” said Ms. Eliscu.
Employers also like to spread the word when their doctors make it on “Top Doctor” lists.
“With Emory physicians making up nearly 50 percent of the list, that’s more than any other health system in Atlanta,” said an Emory University press release after nearly half of the university’s doctors made the Top Doctors list in Atlanta magazine.
Patients may be impressed: What about your peers?
Dr. St. Louis said that making some of these lists is less impressive than having a peer-reviewed journal article or receiving professional awards.
“Just because a physician is listed in a magazine as a ‘top doctor’ does not mean they are the best. There are far more medical, clinical, and scientific points to consider than just a pretty picture in a style magazine,” she said.
Wanda Filer, MD, MBA, who practiced family medicine until last year when she became chief medical officer for VaxCare in Orlando, said she ignores the many congratulatory letters in the mail announcing that she’s made one list or another.
“I don’t put much credence in the lists. I get notifications fairly often, and to me it always looks like they’re trying to sell a plaque. I’d rather let my work speak for itself.”
Arlen Meyers, MD, MBA, president and CEO of the Society of Physician Entrepreneurs and a paid strategic adviser to RYTE, a data-driven site for “best doctors” and “best hospitals,” said he received several of these “top doctor” awards when he was a professor of otolaryngology at the University of Colorado.
He has been critical of these awards for some time. “These doctor beauty pageants may be good for business but have little value for patients.”
He would like to see a new approach that is driven by data and what patients value. “If I have a lump in my thyroid, I want to know the best doctor to treat me based on outcomes data.”
He said a good rating system would include a data-driven approach based on treatment outcomes, publicly available data, price transparency, and patient values.
Whether a physician feels honored to be named a top physician or sees little value in it, most doctors are aware of the list’s marketing value for their practices and many choose to make use of it.

Thousands of doctors get a shout out every year when they make the “Top Doctor” lists in various magazines. Some may be your colleagues or competitors. Should you be concerned if you’re not on the list?
Best Doctor lists are clearly popular with readers and make money for the magazines. They can also bring in patient revenue for doctors and their employers who promote them in news releases and on their websites.
For doctors on some of the top lists, the recognition can bring not only patients, but national or international visibility.

Black men at higher risk for mortality from sleep apnea
There has been a flattening of sleep apnea–related mortality rates in the United States over the past 10 years. The exception is among Black men, for whom mortality from sleep apnea has continuously increased over the past 21 years, new research shows.
“OSA (obstructive sleep apnea) has been recognized as an important cause of medical morbidity and mortality and contributes to the development of systemic hypertension, cardiovascular disease, and abnormalities in glucose metabolism,” noted Yu-Che Lee, MD, University at Buffalo–Catholic Health System, Buffalo, N.Y., and colleagues.
“This study provides the first systematic assessment and demonstrates remarkable demographic disparities of age-adjusted sleep apnea–related mortality in the U.S., with higher rates in males than females and Blacks than Whites,” they concluded.
The study was published online in Sleep Medicine.
Twenty-one year interval
Data on sleep apnea–related mortality were obtained from the National Center for Health Statistics and were provided by the Centers for Disease Control and Prevention for the years 1999-2019. Over that 21-year interval, sleep apnea was documented as the underlying cause of death in 17,053 decedents, including 2,593 Black patients and 14,127 White patients.
The age-adjusted mortality rate attributed to sleep apnea was 2.5 per 1,000,000 population. The mortality rate was higher for men, at 3.1 per 1,000,000, than among women, 1.9 per 1,000,000 (P < .001). For both sexes, “unadjusted mortality rates were higher in groups aged ≥ 35 years, and the highest mortality rates were observed in groups aged 75-84,” the authors noted. The rate was 11.3 per 1,000,000 for those aged 75-84 and 13.3 per 1,000,000 for those older than 85.
This was also true among Black and White patients, the authors added, although the age-adjusted mortality rate was higher among Black patients than among other racial groups, at 3.5 per 1,000,000 (P < .001). “Over the 21-year study period, the overall age-adjusted mortality rate rose from 1.2 per 1,000,000 population in 1999 to 2.8 per 1,000,000 in 2019,” Dr. Lee and colleagues noted. While the annual percentage change in sleep apnea–related mortality rose by 10.2% (95% confidence interval [CI], 8.4%-12.0%) between 1999 and 2018, no significant change was observed between 2008 and 2019.
On the other hand, when examined by race and sex, age-adjusted mortality rates increased significantly by an annual percentage change of 7.5% (95% CI, 3.3%-11.9%) among Black women and by 8.2% (95% CI, 6.8%-9.6%) between 1999 and 2009 in White men and by 11.5% (95% CI, 8.9%-14.1%) in White women. “Again, these uptrends were no longer observed after that time interval,” the authors stressed.
Only among Black men was there no turning point in age-adjusted mortality rates; they experienced a steady, significant, 2.7% (95% CI, 1.2%-4.2%) annual percent increase in age-adjusted mortality rate between 1999 and 2019. The highest age-adjusted mortality rate for Black persons was recorded in Indiana, at 6.5 per 1,000,000 population; Utah recorded the highest mortality rate for White persons, at 5.7 per 1,000,000.
For both Black persons and White persons, the lowest mortality rates were in New York, at 1.2 per 1,000,000 and 1.5 per 1,000,000, respectively. Among four geographic regions analyzed, the highest age-adjusted mortality rates were in the Midwest for both sexes; Black men in the West and those in three other regional groups in the Northwest had the lowest mortality rates.
Multiple causes of death
Black women were more likely to have multiple causes of death, including cardiac arrest, heart failure, and hypertension. White women were more likely to die of arrhythmia, respiratory failure, pneumonia, and depression. Black men were also more likely to die of cardiac arrest, hypertension, and obesity; arrhythmias, ischemic heart disease, and chronic obstructive pulmonary disease were more common in White men.
The authors pointed out that continuous positive airway pressure (CPAP) is the mainstay of therapy for adults with OSA, but many studies have demonstrated decreased CPAP adherence among Black persons. For example, one report indicated that Black persons use CPAP on average 92 minutes less a day after 1 month of therapy than do White persons, for reasons that are not well understood. Asked by this news organization why Black men are so adversely affected by sleep apnea, Dr. Lee pointed out that studies have shown that sleep apnea is more severe in Black men when first diagnosed.
“We know that the severity of sleep apnea is a risk factor for mortality and cardiovascular outcomes,” he said, “so maybe delayed diagnosis, delayed treatment, and noncompliance with CPAP among Black men may help explain why mortality from sleep apnea among Black men has continued to increase.” Why nonadherence to CPAP is higher among Black men is also not clear. Even when access to CPAP is equal for Black patients and White patients, studies have found that rates of noncompliance to CPAP are higher among Black persons than among White patients.
“This is again a hypothesis,” Dr. Lee emphasized, “but perhaps health literacy among Blacks is lower than it is among White patients, and they may not realize that CPAP can improve health outcomes from sleep apnea,” he suggested. The use of CPAP requires a high level of self-advocacy, which might explain part of their noncompliance.
Other health behaviors and environmental factors may contribute to the tendency among Black patients to be noncompliant with CPAP. “I think this is the first study to show that there is a significant racial disparity in mortality from sleep apnea among Black males, and it should give physicians some insight into the problem; they can develop strategies or interventions to try and reduce racial disparities in outcomes from sleep apnea,” Dr. Lee said.
“So, this study is only the beginning, and we need to have more insight and strategies to improve outcomes among Black males,” he affirmed.
Asked to comment on the findings, Diego Mazzotti, PhD, said the study helps bring attention to existing health disparities related to sleep disorders. “Some of the trends observed by the authors seem to explain the increased recognition that sleep apnea may be a risk factor for cardiovascular morbidity and mortality,” said Dr. Mazzotti, assistant professor in the division of medical informatics at the University of Kansas Medical Center in Kansas City.
“Trends in certain minority groups and certain regions in the U.S. suggest that physicians need to recognize the impact of untreated sleep apnea on the cardiovascular health of these patients,” he said.
Dr. Lee and Dr. Mazzotti have disclosed no relevant financial relationships.

Hybrid ACC 2022 resurrects the live scientific session
Regardless of the pandemic’s sometimes mercurial behavior, the cardiology community appears set to reclaim valued traditions perhaps taken for granted in the pre-COVID era.
They include the bustling scientific congress and its myriad educational and networking prospects, along with pleiotropic effects like unplanned reunions with colleagues and catching up face-to-face with old friends.
That seems evident in the growing number of registrants for live attendance at at the annual scientific sessions of the American College of Cardiology, set for this Saturday through Monday in Washington as well as virtually, for a global reach that was unattainable in the pre-COVID era.
Registrations had hit the 11,000 mark and were picking up speed in recent weeks, ACC 2022 cochair Pamela B. Morris, MD, Medical University of South Carolina, Charleston, said at a mid-March presentation to the media.
They had reached about 12,880 and were still climbing a week before the conference, the ACC confirmed to this news organization. By then the professional registration had surpassed 9,900, of whom more than two-thirds reported plans to attend in person.
Dr. Morris said there had been 117 international submissions for what turned out to be 39 coveted spots on the meeting’s Late-Breaking Clinical Trial (LBCT) and Featured Clinical Research agenda spread across eight separate sessions.
On-site participants at the Walter E. Washington Convention Center should head for the Main Tent in Hall D for all LBCT presentations; venues for the Featured Clinical Research sessions are as noted below. Their real-time virtual equivalents will reside on the online platform’s Hot Topics channel. All noted session times are Eastern Daylight Time.
Saturday, April 2, 9:30 a.m.–10:30 a.m. Joint American College of Cardiology/Journal of the American College of Cardiology LBCT (I)
Leading off the conference’s first LBCT session, the randomized VALOR-HCM trial explored whether 16 weeks of mavacamten (MyoKardia) could help patients with severe obstructive hypertrophic cardiomyopathy (HCM) avoid septal reduction therapy, either surgical or by alcohol ablation.
The 22-center VALOR-HCM trial with an estimated enrollment of 100 follows EXPLORER-HCM, which in 2020 suggested the novel myosin-inhibiting agent could improve symptoms, exercise capacity, cardiac remodeling, and quality of life in such patients.
Simply advising people with heart failure (HF) to consume less salt is one thing, but it’s another to show them clinical trial evidence that it might help keep them out of the hospital. The SODIUM-HF (Study of Dietary Intervention Under 100 mmol in Heart Failure) study, conducted at 27 sites in six countries, sought to provide that evidence.
The trial randomly assigned 1,000 patients with NYHA class 2-3 HF to consume no more than 1,500 mg/day in sodium or to receive standard advice to limit sodium intake, and followed them for a year for the endpoint of death from any cause, cardiovascular (CV) hospitalization, or CV emergency department visit.
SODIUM-HF “may provide a rigorous evidence base for sodium restriction in patients with heart failure and may truly change our practice and how we recommend dietary modification,” ACC 2022 vice chair Douglas E. Drachman, MD, Massachusetts General Hospital, Boston, said at the media presentation.
In the same session, the CHAP (Chronic Hypertension and Pregnancy) study explored whether blood pressure (BP) control in pregnant women with new or untreated chronic hypertension could help avert preeclampsia, poor fetal outcomes, and other adverse events.
CHAP assigned about 2,400 women to receive either stepwise antihypertensive therapy to a BP goal of 140/90 mm Hg or lower or no such meds unless their BP reached or exceeded 160/105 mm Hg. Stepwise therapy featured either labetalol or extended-release nifedipine to start, the other agent added as necessary.
The LBCT block also includes the POISE-3 (Perioperative Ischemic Evaluation-3) comparison of the hemostatic agent tranexamic acid vs. placebo in nearly 10,000 patients undergoing noncardiac surgery. A separate randomization of the same cohort, to be reported at a Monday LBCT session, compared pre- and perioperative BP-control strategies.

This session features a subgroup analysis by age from the REVERSE-IT trial, which had previously showcased the monoclonal antibody bentracimab (PhaseBio Pharmaceuticals) for its ability to reverse the antiplatelet effects of ticagrelor.
REVERSE-IT is accompanied on the schedule by several secondary-endpoint presentations from trials whose primary outcomes have already been presented at meetings or in the journals.
They include the SCORED trial of sotagliflozin in patients with diabetes and chronic kidney disease (CKD); COMPLETE, which explored complete revascularization of multivessel coronary disease at primary stenting; and the FAME-3 comparison of coronary bypass surgery (CABG) vs. percutaneous coronary intervention (PCI) guided by fractional flow reserve (FFR) readings.
The session is to conclude with EDIT-CMD, which was a small, randomized assessment of diltiazem for improving microvascular dysfunction in patients with chronic angina despite nonobstructive coronary disease.

The SuperWIN (Supermarket Web Intervention) study tested an innovative strategy for community-based promotion of healthy lifestyle choices: point-of-purchase dietary education for grocery shoppers with an online instructional component, and follow-up to determine whether it influenced future food choices.
“Dietary interventions are notoriously difficult for us to implement, let alone to study scientifically,” Dr. Drachman observed. “So we think that there may be opportunity for dietary interventions to be best implemented at grocery stores where people are doing their shopping for food.”
SuperWIN compared supermarket shoppers with at least one CV risk factor who participated in the education intervention to a nonintervention control group for any changes in their DASH scores. The scores reflected consistency with the venerable DASH diet based on participants’ food purchases over 3 months.
In the same session, the MITIGATE trial explored whether daily administration of icosapent ethyl (Vascepa) might cut the risk of upper respiratory infection (especially from SARS-CoV-2 or seasonal influenza virus) in persons 50 or older with a history of clinical coronary, neurovascular, or peripheral vascular disease or revascularization. The trial has an estimated enrollment of 39,600.
Accompanying SuperWIN and MITIGATE are studies of several dyslipidemia drugs, including the discontinued antisense agent vupanorsen (Pfizer), as tested in TRANSLATE-TIMI 70; the PCSK9 inhibitor alirocumab (Praluent), explored for its effects on coronary plaque volume and composition in the PACMAN-AMI trial; and the APOLLO trial, a phase 1 evaluation of SLN360 (Silence Therapeutics), a short interfering ribonucleic acid (siRNA) that suppresses the molecular machinery in the liver that produces lipoprotein(a), or Lp(a).
The 32-patient APOLLO trial’s recently released top-line results suggested that SLN360 at varying dosages reduced Lp(a) levels by about one-half to more than 90%. Although elevated Lp(a) is known to track with CV risk, it remains to be shown whether dropping Lp(a) levels pharmacologically is protective.
Sunday, April 3, 9:45 a.m.–11:00 a.m. Joint American College of Cardiology/New England Journal of Medicine LBCT (III)
The meeting’s all-HF late-breaker session includes the METEORIC-HF trial, which compared the myotropic agent omecamtiv mecarbil (Cytokinetics) against placebo for effects on exercise performance over 20 weeks. The trial entered 276 patients with HF with reduced ejection fraction (HFrEF) and reduced peak VO2.
The GALACTIC-HF trial had previously suggested that the drug improved the risk of HF-related events or CV death in more than 8000 patients with HFrEF, those with the lowest ejection fractions benefiting the most.
This block of trials also features DIAMOND, the latest trial with a gemologic name to look at the potassium sequestrant patiromer (Veltassa) for any protection against hyperkalemia, a familiar side effect of renin-angiotensin-aldosterone inhibitors. DIAMOND tested patiromer in 878 patients with HFrEF who were on beta-blockers and other HF-appropriate medications and had a history of drug-associated hyperkalemia.
Previously, the AMBER trial of patients with CKD or refractory hypertension on spironolactone had suggested the drug might be protective enough against hyperkalemia to allow higher and more consistent dosing of BP-lowering agents.
Also in the session: the randomized IVVE (Influenza Vaccine to Prevent Adverse Vascular Events) trial, with an estimated 5,000 patients with HF in Africa, Asia, and the Middle East; PROMPT-HF, with a projected 1,310 HF patients and billed as a cluster-randomized pragmatic trial of a strategy for improving guideline-directed outpatient medical therapy; and MAVA-LTE, the long-term extension study of an estimated 310 patients who were in the MAVERICK-HCM and EXPLORER-HCM mavacamten trials.

The arrhythmia-centric session includes PARTITA, with its estimated 590 patients with primary- or secondary-prevention implantable cardioverter-defibrillators (ICDs). The trial followed them initially for burden of untreated nonsustained ventricular tachycardia (VT) or events treated with anti-tachycardia pacing. Then it randomly assigned those who experienced a first appropriate ICD shock to either immediate VT ablation or standard care. The latter included ablation on next occurrence of arrhythmic storm.
Investigational oral factor XIa inhibitors, viewed by many as potentially safer as anticoagulants than contemporary oral inhibitors of factor Xa, are now on the scene and include milvexian (Bristol-Myers Squibb/Janssen) and, lately, asundexian (BAY 2433334; Bayer). The latter agent was compared to the factor Xa inhibitor apixaban (Eliquis) in 753 patients with AF in the phase 2 PACIFIC-AF trial, which looked at the newer drug’s safety and optimal dosing.
Also on the bill: a long-term follow-up of the mAFA-2 (Mobile AF Application 2) extension study, which explored the value of a smartphone-based atrial fibrillation (AF) screening app for improving risk of AF-related events; a presentation billed as “Residual Leaks Post Left Atrial Appendage Occlusion”; and one that declares “low rates of guideline-directed care” to be “associated with higher mortality” in patients with pacemakers or ICDs.
Monday, April 4, 8:30 a.m.–9:45 a.m. LBCT IV
This session is to open with the PROTECT trial, which sought to determine whether perioperative “aggressive warming” may be cardioprotective in patients with CV risk factors undergoing noncardiac surgery. Its estimated 5,100 patients were randomly assigned to a procedure that achieves normothermia, that is 37° C (98.6° F), vs. standard care in which patients’ core temperature may decline to no further than 35.5° C (95.9° F).
Next on the list are a second POISE-3 comparison of BP-control strategies comparing hypotension avoidance vs. hypertension avoidance in patients undergoing noncardiac surgery; the pivotal CLASP 2 TR trial of patients with symptomatic tricuspid regurgitation on optimal medical therapy with vs. without treatment with the Edwards PASCAL Transcatheter Repair System; and one said to provide “insights from the Corevalve US Pivotal and SURTAVI trials” on 5-year incidence, timing, and predictors of hemodynamic valve deterioration transcatheter and surgical aortic bioprostheses.”
Rounding out the block of presentations: the ADAPT-TAVR comparison of the factor Xa inhibitor edoxaban (Lixiana) to dual-antiplatelet therapy for prevention of leaflet thrombosis after successful transcatheter aortic valve replacement (TAVR). The 235-patient trial was conducted at five centers in South Korea, Hong Kong, and Taiwan.
Monday, April 4, 11:00–12:15 p.m. LBCT V
This session includes the FLAVOUR randomized comparison of PCI guided by either FFR or intravascular ultrasound (IVUS) in 1,700 patients with 40%-70% stenoses. The patients from centers in China and South Korea were followed for death from any cause, MI, or any repeat revascularization at 24 months.
Also scheduled: the 2-year report on 4,000 patients with ST-segment elevation MI (STEMI) in the ACC-sponsored quality improvement program GHATI (Global Heart Attack Treatment Initiative); the GIPS-4 myocardial protection study of an estimated 380 patients with STEMI assigned to receive pre- and post-PCI infusions of sodium thiosulfate or placebo, with infarct size at 4 months as the primary endpoint; and a randomized test of an arrhythmia-monitoring implant for influence on clinical outcomes in 802 patients with a history of MI but no pacemaker or ICD indication, called BIO-GUARD-MI,
Last in the session: the Chocolate Touch Study of peripheral-artery angioplasty using a drug-coated balloon (DCB) with a confectionery name that treats lesions not with theobromine, but the antiproliferative mainstay paclitaxel.
The randomized comparison of the Chocolate Touch DCB (TriReme Medical) and the more established Lutonix DCB (Bard) assigned a projected 585 patients with symptomatic peripheral vascular disease to treatment of superficial femoral or popliteal artery lesions with one of the two paclitaxel-coated balloon catheters.
Monday, April 4, 12:45–2 p.m. Featured Clinical Research III. Room 143A
The final session features five subgroup analyses or other updates from trials that have already reported their primary outcomes. Among them is the SPYRAL HTN-ON MED trial, which helped to revitalize hopes for renal denervation therapy as a catheter-based treatment for drug-resistant hypertension by showing significant effects on both systolic and diastolic blood pressure. The new data follow the trial’s more than 400 patients out to 3 years.
There is also a symptom and quality-of-life analysis from the 530-patient EMPULSE trial of 530 patients with stabilized acute HF assigned in-hospital to start on empagliflozin (Jardiance) or placebo. The trial made a splash last year when it reported a significant improvement in risk for death or HF rehospitalization for its patients put on the SGLT2 inhibitor.
A secondary analysis from CANTOS is also featured; the trial had randomly assigned more than 10,000 patients with recent acute MI and elevated C-reactive protein (CRP) levels to receive or not receive the anti-inflammatory canakinumab (Ilaris). Those assigned to active therapy showed benefits for a range of outcomes, including CV mortality and stroke, but no decreases in cholesterol levels. Billing for the new CANTOS analysis promises insights on the “differential impact of residual inflammatory risk and residual cholesterol risk among atherosclerosis patients with and without chronic kidney disease.”
The session also features “trends and final results” from the NACMI (North American COVID-19 Myocardial Infarction) registry, which had shown excellent primary-PCI results without compromise of door-to-balloon times in patients with confirmed SARS-CoV-2 infection; and a FIDELITY analysis of cardiorenal endpoints by history of CV disease in the study’s more than 13,000 patients with diabetes and CKD assigned to placebo or finerenone (Kerendia), a mineralocorticoid receptor antagonist.

Regardless of the pandemic’s sometimes mercurial behavior, the cardiology community appears set to reclaim valued traditions perhaps taken for granted in the pre-COVID era.
They include the bustling scientific congress and its myriad educational and networking prospects, along with pleiotropic effects like unplanned reunions with colleagues and catching up face-to-face with old friends.
That seems evident in the growing number of registrants for live attendance at at the annual scientific sessions of the American College of Cardiology, set for this Saturday through Monday in Washington as well as virtually, for a global reach that was unattainable in the pre-COVID era.
Registrations had hit the 11,000 mark and were picking up speed in recent weeks, ACC 2022 cochair Pamela B. Morris, MD, Medical University of South Carolina, Charleston, said at a mid-March presentation to the media.
They had reached about 12,880 and were still climbing a week before the conference, the ACC confirmed to this news organization. By then the professional registration had surpassed 9,900, of whom more than two-thirds reported plans to attend in person.
Dr. Morris said there had been 117 international submissions for what turned out to be 39 coveted spots on the meeting’s Late-Breaking Clinical Trial (LBCT) and Featured Clinical Research agenda spread across eight separate sessions.
On-site participants at the Walter E. Washington Convention Center should head for the Main Tent in Hall D for all LBCT presentations; venues for the Featured Clinical Research sessions are as noted below. Their real-time virtual equivalents will reside on the online platform’s Hot Topics channel. All noted session times are Eastern Daylight Time.

Leading off the conference’s first LBCT session, the randomized VALOR-HCM trial explored whether 16 weeks of mavacamten (MyoKardia) could help patients with severe obstructive hypertrophic cardiomyopathy (HCM) avoid septal reduction therapy, either surgical or by alcohol ablation.
The 22-center VALOR-HCM trial with an estimated enrollment of 100 follows EXPLORER-HCM, which in 2020 suggested the novel myosin-inhibiting agent could improve symptoms, exercise capacity, cardiac remodeling, and quality of life in such patients.

SuperWIN compared supermarket shoppers with at least one CV risk factor who participated in the education intervention to a nonintervention control group for any changes in their DASH scores. The scores reflected consistency with the venerable DASH diet based on participants’ food purchases over 3 months.
In the same session, the MITIGATE trial explored whether daily administration of icosapent ethyl (Vascepa) might cut the risk of upper respiratory infection (especially from SARS-CoV-2 or seasonal influenza virus) in persons 50 or older with a history of clinical coronary, neurovascular, or peripheral vascular disease or revascularization. The trial has an estimated enrollment of 39,600.
Accompanying SuperWIN and MITIGATE are studies of several dyslipidemia drugs, including the discontinued antisense agent vupanorsen (Pfizer), as tested in TRANSLATE-TIMI 70; the PCSK9 inhibitor alirocumab (Praluent), explored for its effects on coronary plaque volume and composition in the PACMAN-AMI trial; and the APOLLO trial, a phase 1 evaluation of SLN360 (Silence Therapeutics), a short interfering ribonucleic acid (siRNA) that suppresses the molecular machinery in the liver that produces lipoprotein(a), or Lp(a).
The 32-patient APOLLO trial’s recently released top-line results suggested that SLN360 at varying dosages reduced Lp(a) levels by about one-half to more than 90%. Although elevated Lp(a) is known to track with CV risk, it remains to be shown whether dropping Lp(a) levels pharmacologically is protective.

The meeting’s all-HF late-breaker session includes the METEORIC-HF trial, which compared the myotropic agent omecamtiv mecarbil (Cytokinetics) against placebo for effects on exercise performance over 20 weeks. The trial entered 276 patients with HF with reduced ejection fraction (HFrEF) and reduced peak VO2.
The GALACTIC-HF trial had previously suggested that the drug improved the risk of HF-related events or CV death in more than 8000 patients with HFrEF, those with the lowest ejection fractions benefiting the most.
This block of trials also features DIAMOND, the latest trial with a gemologic name to look at the potassium sequestrant patiromer (Veltassa) for any protection against hyperkalemia, a familiar side effect of renin-angiotensin-aldosterone inhibitors. DIAMOND tested patiromer in 878 patients with HFrEF who were on beta-blockers and other HF-appropriate medications and had a history of drug-associated hyperkalemia.
Previously, the AMBER trial of patients with CKD or refractory hypertension on spironolactone had suggested the drug might be protective enough against hyperkalemia to allow higher and more consistent dosing of BP-lowering agents.
Also in the session: the randomized IVVE (Influenza Vaccine to Prevent Adverse Vascular Events) trial, with an estimated 5,000 patients with HF in Africa, Asia, and the Middle East; PROMPT-HF, with a projected 1,310 HF patients and billed as a cluster-randomized pragmatic trial of a strategy for improving guideline-directed outpatient medical therapy; and MAVA-LTE, the long-term extension study of an estimated 310 patients who were in the MAVERICK-HCM and EXPLORER-HCM mavacamten trials.
Sunday, April 3, 12:15–1:30 p.m. Featured Clinical Research II. Main Tent, Hall D
The arrhythmia-centric session includes PARTITA, with its estimated 590 patients with primary- or secondary-prevention implantable cardioverter-defibrillators (ICDs). The trial followed them initially for burden of untreated nonsustained ventricular tachycardia (VT) or events treated with anti-tachycardia pacing. Then it randomly assigned those who experienced a first appropriate ICD shock to either immediate VT ablation or standard care. The latter included ablation on next occurrence of arrhythmic storm.
Investigational oral factor XIa inhibitors, viewed by many as potentially safer as anticoagulants than contemporary oral inhibitors of factor Xa, are now on the scene and include milvexian (Bristol-Myers Squibb/Janssen) and, lately, asundexian (BAY 2433334; Bayer). The latter agent was compared to the factor Xa inhibitor apixaban (Eliquis) in 753 patients with AF in the phase 2 PACIFIC-AF trial, which looked at the newer drug’s safety and optimal dosing.
Also on the bill: a long-term follow-up of the mAFA-2 (Mobile AF Application 2) extension study, which explored the value of a smartphone-based atrial fibrillation (AF) screening app for improving risk of AF-related events; a presentation billed as “Residual Leaks Post Left Atrial Appendage Occlusion”; and one that declares “low rates of guideline-directed care” to be “associated with higher mortality” in patients with pacemakers or ICDs.
Monday, April 4, 8:30 a.m.–9:45 a.m. LBCT IV
This session is to open with the PROTECT trial, which sought to determine whether perioperative “aggressive warming” may be cardioprotective in patients with CV risk factors undergoing noncardiac surgery. Its estimated 5,100 patients were randomly assigned to a procedure that achieves normothermia, that is 37° C (98.6° F), vs. standard care in which patients’ core temperature may decline to no further than 35.5° C (95.9° F).
Next on the list are a second POISE-3 comparison of BP-control strategies comparing hypotension avoidance vs. hypertension avoidance in patients undergoing noncardiac surgery; the pivotal CLASP 2 TR trial of patients with symptomatic tricuspid regurgitation on optimal medical therapy with vs. without treatment with the Edwards PASCAL Transcatheter Repair System; and one said to provide “insights from the Corevalve US Pivotal and SURTAVI trials” on 5-year incidence, timing, and predictors of hemodynamic valve deterioration transcatheter and surgical aortic bioprostheses.”
Rounding out the block of presentations: the ADAPT-TAVR comparison of the factor Xa inhibitor edoxaban (Lixiana) to dual-antiplatelet therapy for prevention of leaflet thrombosis after successful transcatheter aortic valve replacement (TAVR). The 235-patient trial was conducted at five centers in South Korea, Hong Kong, and Taiwan.
Monday, April 4, 11:00–12:15 p.m. LBCT V
This session includes the FLAVOUR randomized comparison of PCI guided by either FFR or intravascular ultrasound (IVUS) in 1,700 patients with 40%-70% stenoses. The patients from centers in China and South Korea were followed for death from any cause, MI, or any repeat revascularization at 24 months.
Also scheduled: the 2-year report on 4,000 patients with ST-segment elevation MI (STEMI) in the ACC-sponsored quality improvement program GHATI (Global Heart Attack Treatment Initiative); the GIPS-4 myocardial protection study of an estimated 380 patients with STEMI assigned to receive pre- and post-PCI infusions of sodium thiosulfate or placebo, with infarct size at 4 months as the primary endpoint; and a randomized test of an arrhythmia-monitoring implant for influence on clinical outcomes in 802 patients with a history of MI but no pacemaker or ICD indication, called BIO-GUARD-MI,
Last in the session: the Chocolate Touch Study of peripheral-artery angioplasty using a drug-coated balloon (DCB) with a confectionery name that treats lesions not with theobromine, but the antiproliferative mainstay paclitaxel.
The randomized comparison of the Chocolate Touch DCB (TriReme Medical) and the more established Lutonix DCB (Bard) assigned a projected 585 patients with symptomatic peripheral vascular disease to treatment of superficial femoral or popliteal artery lesions with one of the two paclitaxel-coated balloon catheters.
Monday, April 4, 12:45–2 p.m. Featured Clinical Research III. Room 143A
The final session features five subgroup analyses or other updates from trials that have already reported their primary outcomes. Among them is the SPYRAL HTN-ON MED trial, which helped to revitalize hopes for renal denervation therapy as a catheter-based treatment for drug-resistant hypertension by showing significant effects on both systolic and diastolic blood pressure. The new data follow the trial’s more than 400 patients out to 3 years.
There is also a symptom and quality-of-life analysis from the 530-patient EMPULSE trial of 530 patients with stabilized acute HF assigned in-hospital to start on empagliflozin (Jardiance) or placebo. The trial made a splash last year when it reported a significant improvement in risk for death or HF rehospitalization for its patients put on the SGLT2 inhibitor.
A secondary analysis from CANTOS is also featured; the trial had randomly assigned more than 10,000 patients with recent acute MI and elevated C-reactive protein (CRP) levels to receive or not receive the anti-inflammatory canakinumab (Ilaris). Those assigned to active therapy showed benefits for a range of outcomes, including CV mortality and stroke, but no decreases in cholesterol levels. Billing for the new CANTOS analysis promises insights on the “differential impact of residual inflammatory risk and residual cholesterol risk among atherosclerosis patients with and without chronic kidney disease.”
The session also features “trends and final results” from the NACMI (North American COVID-19 Myocardial Infarction) registry, which had shown excellent primary-PCI results without compromise of door-to-balloon times in patients with confirmed SARS-CoV-2 infection; and a FIDELITY analysis of cardiorenal endpoints by history of CV disease in the study’s more than 13,000 patients with diabetes and CKD assigned to placebo or finerenone (Kerendia), a mineralocorticoid receptor antagonist.

Children and COVID: The long goodbye continues
COVID-19 continues to be a diminishing issue for U.S. children, as the number of new cases declined for the ninth consecutive week, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.
the AAP and CHA said in their weekly COVID report. The most recently infected children brought the total number of COVID-19 cases to just over 12.8 million since the pandemic began.
Other measures of COVID occurrence in children, such as hospital admissions and emergency department visits, also followed recent downward trends, although the sizes of the declines are beginning to decrease. Admissions dropped by 13.3% during the week ending March 26, but that followed declines of 25%, 20%, 26.5% and 24.4% for the 4 previous weeks, data from the Centers for Disease Control and Prevention show.
The slowdown in ED visits started a couple of weeks earlier, but the decline is still ongoing. As of March 25, ED visits with a confirmed COVID diagnosis represented just 0.4% of all visits for children aged 0-11 years, down from 1.1% on Feb. 25 and a peak of 14.3% on Jan. 15. For children aged 12-15, the latest figure is just 0.2%, compared with 0.5% on Feb. 25 and a peak of 14.3% on Jan. 9, the CDC reported on its COVID Data Tracker.
Although he was speaking of the nation as a whole and not specifically of children, Anthony Fauci, MD, the director of the National Institute of Allergy and Infectious Diseases, recently told the Washington Post that, “unless something changes dramatically,” another major surge isn’t on the horizon.
That sentiment, however, was not entirely shared by Moderna’s chief medical officer, Paul Burton, MD, PhD. In an interview with WebMD, he said that another COVID wave is inevitable and that it’s too soon to dismantle the vaccine infrastructure: “We’ve come so far. We’ve put so much into this to now take our foot off the gas. I think it would be a mistake for public health worldwide.”
Disparities during the Omicron surge
As the country puts Omicron in its rear view mirror, a quick look back at the CDC data shows some differences in how children were affected. At the surge’s peak in early to mid-January, Hispanic children were the most likely to get COVID-19, with incidence highest in the older groups. (See graph.)
At their peak week of Jan. 2-8, Hispanic children aged 16-17 years had a COVID rate of 1,568 cases per 100,000 population, versus 790 per 100,000 for White children, whose peak occurred a week later, from Jan. 9 to 15. Hispanic children aged 5-11 (1,098 per 100,000) and 12-15 (1,269 per 100,000) also had the highest recorded rates of the largest racial/ethnic groups, while Black children had the highest one-week rate, 625 per 100,000, among the 0- to 4-year-olds, according to the CDC.
