The NCAA has announced that all winter and spring championships for this academic year have been canceled, which includes the men's and women's basketball tournaments, which were slated to begin next week. The announcement also impacts other major tournaments such as the Frozen Four and the College World Series.The move was made as coronavirus cases spread nationally. The announcement also comes as MLB, MLS, NHL and NBA all have decided to postpone contests indefinitely. The NCAA released the following statement:"Today, NCAA President Mark Emmert and the Board of Governors canceled the Division I men’s and women’s 2020 basketball tournaments, as well as all remaining winter and spring NCAA championships. This decision is based on the evolving COVID-19 public health threat, our ability to ensure the events do not contribute to spread of the pandemic, and the impracticality of hosting such events at any time during this academic year given ongoing decisions by other entities." 1001

The FDA said on Tuesday it has developed guidelines to take plasma from coronavirus survivors to treat patients who are critically ill from the virus. The FDA said on Tuesday that It is possible that convalescent plasma contains antibodies to the coronavirus and might be effective against the infection. The FDA said that although the announcement is promising, convalescent plasma has not been shown to be effective in every disease studied. The FDA is not approving using plasma as a treatment, instead using it as a clinical trial and for the treatment of those who are critically ill. "Given the public health emergency that the expanding COVID-19 outbreak presents, while clinical trials are being conducted, FDA is facilitating access to COVID-19 convalescent plasma for use in patients with serious or immediately life-threatening COVID-19 infections," the FDA said. The plasma will be collected from recovered individuals only if they are eligible to donate blood. The FDA said on Sunday that it was altering its guidelines on Risk Evaluation and Mitigation Strategy (REMS)-required testing, which allows healthcare providers to weigh the benefits of an experimental drug over its risks.“The FDA recognizes that during the COVID-19 public health emergency, the completion of some REMS-required laboratory testing or imaging studies may be difficult because patients suspected of having COVID-19 may be self-isolating and/or subject to quarantine,” said FDA Principal Deputy Commissioner Amy Abernethy, M.D., Ph.D. “Under these circumstances, undergoing testing or imaging studies in order to obtain a drug that is subject to a REMS can put patients and others at risk for transmission of the coronavirus. We will continue to work with sponsors to ensure that patients have appropriate access to the medications they need.” 1843

The medical journal BMJ published a report today that links a lower risk of early death to higher levels of physical activity at any intensity in middle-aged and older people.Previous studies have repeatedly suggested that any type of sedentary behavior, such as sitting still, is not good for your health. Being sedentary for 9.5 hours or more a day, excluding sleeping time, is associated with an increased risk of death.Led by Prof. Ulf Ekelund of the Norwegian School of Sports Sciences located in Oslo, Norway, researchers analyzed studies that assessed how physical activity and sedentary time were linked with risk of an early death.Using accelerometers -- a wearable device that tracks the volume and intensity of activity -- to measure total activity, intensity levels were separated into categories of light, moderate and vigorous.Cooking or washing dishes were examples of light intensity, brisk walking or mowing the lawn were considered moderate intensity, and jogging or carrying heavy loads were used as examples of vigorous intensity.The risk of death for participants was approximately five times higher for those who were inactive compared to those who were the most active, according to the researchers.The study was conducted in the United States and Western Europe on 36,383 adults who were at least 40 years old with an average age of 62. Participants were tracked over an average of 5.8 years.However, the findings in the study may not apply to other populations and younger people.At least 150 minutes of moderate intensity or 75 minutes of vigorous physical activity each week are recommended guidelines, 1642
