In a finding that should encourage scientists who are racing to develop coronavirus vaccines, a new study out of Iceland suggests that immunity to the disease may not be as fleeting as first thought. Among 30,000 Icelandic residents who were tested for antibodies to COVID-19, researchers discovered the antibodies stayed in people’s systems for at least four months, the study found. Of those who tested positive for the coronavirus, 487 had received multiple antibody tests. In the first two months after a patient was diagnosed, the antibodies that can confer immunity rose significantly. For the next two months, antibody levels remained stable, according to the study published Tuesday in the New England Journal of Medicine. In a commentary that accompanied the study, scientists from Harvard University and the U.S. National Institutes of Health noted that while the Icelandic research focused on a largely homogeneous population, “this study provides hope that host immunity to this unpredictable and highly contagious virus may not be fleeting and may be similar to that elicited by most other viral infections.” Earlier research on coronavirus antibodies had indicated that immunity might be short-lived, leaving people vulnerable to reinfection. But the Icelandic study offers hope that a vaccine that triggers a strong immune response will have a longer-lasting effect than some had believed. Interestingly, the Icelandic researchers also found that women, nonsmokers…  read on >

Men: A bulging belly may be bad for more than your heart. A new study suggests it might also up your risk of dying from prostate cancer. Researchers analyzed data from more than 218,000 men in Britain who were free of cancer when they enrolled in the U.K. BioBank study between 2006 and 2010. Over almost 11 years of follow-up, nearly 600 of the men died of prostate cancer. There was no clear association between risk of prostate cancer death and body mass index (BMI — an estimate of body fat based on weight and height) or total body fat percentage. However, there was a link between high levels of fat around the belly and waist (central adiposity) and prostate cancer death risk, according to the study being presented this week at the virtual European and International Conference on Obesity. Men in the top 25% for waist circumference were 35% more likely to die of prostate cancer than men in the bottom 25%, while those in the top 25% for waist-to-hip ratio were 34% more likely to die than men in the bottom 25%. “We found a significant association between concentration of body fat around the belly and waist and the risk of prostate cancer death, but no clear association between total body fat and risk of prostate cancer death,” said study author Aurora Pérez-Cornago,…  read on >

THURSDAY, Sept. 3, 2020 (Healthday News) — Colleges across America struggled to control coronavirus outbreaks on campus, even as Dr. Anthony Fauci warned on Wednesday that sending students home after an outbreak is “the worst thing you could do.” Universities continue to be hit with alarming infection rates, and many have already switched to online learning, the Washington Post reported. In some instances, students have been told to move out of their dorms and return home, the newspaper said. But Fauci, the nation’s top infectious diseases expert, told NBC’s “Today” show that it was important to ensure that infected students are placed in isolation, “but don’t have them go home, because they could be spreading it in their home state.” Along with shutting down in-person instruction, many universities are cracking down on student activities that fuel the spread of COVID-19, the Post reported. At the University of Illinois, where more than 700 students have tested positive in less than two weeks, administrators instituted a ban on “gathering in small or large groups under any circumstances.” In what is the equivalent of stay-at-home orders, students will not be allowed to leave their dorm rooms for anything besides essential activities — attending class, buying groceries, solo outdoor exercise, religious services and medical visits. The college also plans to aggressively crack down on parties, the Post reported. “We…  read on >

In the midst of the ‘Me Too’ movement, a new study finds that people sexually harassed at work may be at increased risk for attempted suicide and suicide. The findings out of Sweden show that workplace sexual harassment may “represent an important risk factor for suicidal behavior,” said study author Linda Magnusson Hanson, an associate professor in the psychology department at Stockholm University, and colleagues. The research included more than 85,000 male and female workers in Sweden who completed a questionnaire between 1995 and 2013. It asked if they’d been sexually harassed at work in the past 12 months by either fellow workers, superiors or by what they termed “others,” such as clients, passengers, students or patients. Overall, nearly 5% of the workers reported workplace sexual harassment: about 2% of men and 7.5% of women. Those who said they were sexually harassed were more likely to be younger, single, divorced, in low-paid but high-strain jobs, and born outside of Europe. The workers were then followed for an average of up to 13 years. During that time, 125 died by suicide and 816 made a suicide attempt. While the study was only observational and did not prove a cause-and-effect link, workplace sexual harassment was associated with a nearly threefold increased risk of suicide and almost doubled increased risk of attempted suicide, the researchers found. The increased…  read on >

Smokers with the most common type of heart rhythm disorder can reduce their risk of stroke and death by giving up cigarettes, a new study says. “Smoking precipitates blood clots that could lead to a stroke, which may be why giving up lowers risk,” said study author So-Ryoung Lee of Seoul National University Hospital in South Korea. But even former smokers had higher odds for stroke compared to never smokers, the study found. “The remaining stroke risk after quitting might be through the damage already caused to the arteries — called atherosclerosis,” Lee said in a European Society of Cardiology news release. Stroke is the most common cause of death in people with atrial fibrillation (a-fib). People with a-fib are five times more likely to have a stroke than those without the heart rhythm disorder. And a-fib increases the risk of death two-fold in women and 1.5-fold in men. Previous research has shown that smokers are at higher risk for a-fib and a subsequent stroke. This study included nearly 98,000 people, average age 61, in South Korea who were diagnosed with a-fib from 2010 to 2016. They were followed until the end of 2017, for a median follow-up of three years. Compared to current smokers, quitters were 30% less likely to have a stroke and 16% less likely to die from any cause. However, quitters…  read on >

Just weeks after colleges across the United States reopened their campuses for the fall semester, thousands of coronavirus infections are cropping up in students and staff alike. More than 1,500 American colleges and universities were tallied in The New York Times survey. That included every four-year public institution, every private college that competes in NCAA sports and others that identified cases. The case total: At least 26,000 cases and 64 deaths have been reported since the pandemic began, the Times reported. The trend is unfolding everywhere. The University of North Carolina at Chapel Hill sent most undergraduates home after COVID-19 clusters popped up in campus housing. In-person classes were delayed at Notre Dame as students tested positive by the hundreds. Clemson, Baylor, Louisville and dozens of other Division I universities have confirmed COVID-19 cases in their athletic departments. Meanwhile, aggressive testing of students moving into dorms turned up scores of cases at Iowa State, the Times reported. Meanwhile, the potential of convalescent plasma as a treatment for severe COVID-19 was still unclear Tuesday, as the World Health Organization cautioned the therapy remains experimental and American scientists challenged a key statistic cited by U.S. officials as grounds for emergency approval of the treatment. In announcing the approval this week, President Donald Trump and two of his top health officials stirred controversy when they used the same…  read on >

Despite the wave of criticism that has followed the U.S. Food and Drug Administration’s emergency approval of convalescent plasma to treat COVID-19 patients, infectious disease experts say the therapy remains promising. Some scientists have questioned both the timing of the approval and the veracity of a key survival statistic cited by FDA Commissioner Dr. Stephen Hahn. And the clinical trials needed to make sure that convalescent plasma really works are not yet complete. Still, survivors’ plasma has been on the list of potential COVID-19 treatments since the pandemic began and an emergency approval for its widespread use was not unexpected, said Dr. Liise-anne Pirofski, chair of biomedical research at the Albert Einstein College of Medicine and Montefiore Medical Center, in New York City. Data coming in from around the world shows that antibody-loaded plasma taken from COVID-19 survivors can help people fighting off an infection, Pirofski said. For example, reports from China have shown that desperately ill patients treated late in their disease with convalescent plasma experienced a very rapid decrease in their viral load, Pirofski noted. There’s also no evidence that convalescent plasma can hurt a person, she added. “I cannot think of one shred of data that I have seen that would suggest harm,” Pirofski said. But scientists still don’t know exactly how effective plasma can be, when it would be best administered…  read on >

Middle-aged men who were anxious or depressed teens are at increased risk for heart attack, according to a large, long-term study. It included more than 238,000 men born between 1952 and 1956 who underwent extensive exams when they were 18 or 19 years old and were followed to age 58. Men diagnosed with anxiety or depression in their late teens had a 20% higher risk of heart attack than those who didn’t, the study showed. The findings only reflect an association. The link was partly, but not fully, explained by poorer ability to cope with everyday stress and lower physical fitness in teens with the mental health conditions, according to findings presented Wednesday at a virtual meeting of the European Society of Cardiology. The takeaway: “Be vigilant and look for signs of stress, depression or anxiety that is beyond the normal teenage angst: Seek help if there seems to be a persistent problem,” suggested study author Cecilia Bergh, a senior lecturer in health sciences at Orebro University in Sweden. “If a healthy lifestyle is encouraged as early as possible in childhood and adolescence it is more likely to persist into adulthood and improve long-term health,” she said in a meeting news release. Bergh said researchers already knew that men who were physically fit but stressed as teens seemed less likely to maintain fitness. “Our previous…  read on >

The first rapid coronavirus test that doesn’t need any special computer equipment to produce results was approved by the U.S. Food and Drug Administration on Wednesday. Made by Abbott Laboratories, the 15-minute test will sell for $5, giving it an edge over similar tests that need to be popped into a small machine, the Associated Press reported. No larger than a credit card, the Abbott test is based on the same technology used to test for the flu, strep throat and other infections. BinaxNOW is the fourth rapid test in the United States that detects COVID-19 antigens, proteins found on the surface of the coronavirus, rather than the virus itself, the AP reported. It’s considered a faster, but less precise, screening method. Abbott’s entry into the rapid COVID-19 test market offers yet another option to expand testing, the AP reported. The FDA also recently gave its blessing to a saliva test from Yale University that bypasses some of the supplies that have led to testing bottlenecks, the wire service said. Neither test can be performed at home. But several companies are developing rapid at-home tests, though none have yet won FDA approval, the AP reported. Abbott’s new test still requires a nasal swab be taken by a health worker, like most older coronavirus tests. The Yale saliva test eliminates the need for a swab, but…  read on >

For a host of reasons, millions worldwide are deciding to give up meat and focus on a plant-based diet. But new research out of Greece is a reminder that not all vegetarian diets are healthy — especially for people who are already obese. “The quality of plant-based diets varies,” concluded a team led by Matina Kouvari of Harokopio University in Athens. Reporting Thursday at the virtual meeting of the European Society of Cardiology (ESC), her team assessed the diets of 146 randomly selected obese people in Athens, who had normal blood pressure, blood cholesterol and blood sugar, and did not yet have heart disease. Their diets were assessed using a questionnaire about their typical eating habits in the previous year. It asked about 156 foods and beverages commonly consumed in Greece. Within 10 years, nearly half of the participants had gone on to develop high blood pressure, high blood cholesterol and high blood sugar — a combination that’s particularly risky for the heart. However, diets focused on healthier plant-based foods were associated with normal blood pressure, blood lipids and blood sugar. These “healthier” vegetarian options included whole grains, fruits, vegetables, nuts, olive oil and tea/coffee, as well as foods made with the least amount of processing. On the other hand, unhealthy plant-based foods — items such as juices, sweetened beverages, refined grains (for example, white…  read on >
