(Reuters) – Here’s a summary of the latest scientific studies on the novel coronavirus. and efforts to find cures and vaccines for COVID-19, an illness caused by the virus.
The severity of COVID-19 linked to food
People who eat meat-free food are more likely to contract COVID-19. moderate to less severe According to a six-country study published Monday in BMJ Nutrition, Prevention & Health, researchers found that a plant-based diet reduced the risk of serious disease by 73%, based on a survey of 2,884 healthcare providers. In cases caring for COVID-19 patients, researchers found a 59 percent reduction in the fatal disease rate when they included those who ate a plant-based diet and those who ate fish but didn̵7;t eat meat. The study cannot prove that certain foods can protect against severe COVID-19, and diet does not reduce the risk of infection. Researchers noted that plant foods are rich in nutrients. Important vitamins and minerals for a healthy immune system. And fish provides vitamin D and omega-3 fatty acids, which have anti-inflammatory properties. However, healthy eating is a problem during the pandemic. According to two presentations this week during a virtual meeting of the American Society for Nutrition, consumption of healthy foods such as vegetables and whole grains has declined. Researchers compared the diets of more than 2,000 Americans before and during the pandemic. in separate studies Researchers who collected food data for June 2020 for 3,916 US adults. It found that many people were consuming more unhealthy sweets, desserts and sugary drinks during the pandemic. “A person may need help to avoid making these dietary changes permanently,” said Dr. Sohyun Park of the U.S. Centers for Disease Control and Prevention. said co-author of the latter study.

There are no serious problems with the AstraZeneca vaccine in Scotland.
Study on the side effects of the COVID-19 vaccine of AstraZeneca in Scotland It was found only to be associated with mostly harmless bleeding. and there is no link to potentially fatal blood clotting in the brain. Also known as CVST, it caused concern in Europe and led to disruptions in its use. Researchers who followed 5.4 million people in Scotland found another patient with the disease. Idiopathic thrombocytopenic purpura (ITP) per 100,000 population after the first AstraZeneca shot. ITP is a treatable condition of low platelets. and did not cause any deaths Among the 1.7 million vaccine recipients in the study, Because of the rarity of CVST, the Scottish study may be too small to draw any conclusions, study co-author Aziz Sheikh from the University of Edinburgh said in a media briefing, the authors of the report on Wednesday in Nature Medicine. “The overall message is just a rare outcome,” Sheikh said. “This is reassuring information” (https://go.nature.com/3crKglC; https://go.nature.com/356SUBI; https: //reut.rs/3gkG48m)
Aspirin does not help hospitalized COVID-19 patients.
Aspirin did not improve survival or reduce disease severity in a study of nearly 15,000 patients hospitalized with COVID-19. Researchers hope that because aspirin helps reduce blood clots in other diseases. Therefore, it may be useful in patients with COVID-19. at high risk of blood clotting problems Patients randomly assigned to take 150 mg of aspirin once a day had fewer blood clots. But there was no risk of getting sick less and requiring mechanical ventilation or a better chance of survival after 28 days, and there was a higher risk of major bleeding complications. This is an unusual problem with aspirin treatment. Researchers reported on medRxiv Tuesday ahead of a peer review. The trial’s co-lead researcher said: “This does not appear to be sufficient to justify widespread use for patients hospitalized with COVID-19” (https://bit.ly/3cu4fQx; https://reut.rs). /3gnY9SO)
Covid-19 control policies still have to be applied. in hot weather
A new study finds If there are no lockdown measures and social distancing measures Weather and congestion will have the greatest impact on the spread of COVID-19. But although the spread of the virus tends to decrease somewhat in warmer climates, summer weather As population density is more important than temperature, according to a report by Imperial College London published Wednesday in PNAS, warmer regions should not be expected to ease movement restrictions. before colder regions especially because “Warmer regions tend to have higher population densities — for example, Florida’s population is more dense than Minnesota,” co-author Will Pearse said in a statement. His team reported the lockdown had a greater effect on temperature or population density. This is because temperature changes have less impact on transmission than policy interventions. “While people are still not vaccinated. Governments must not cancel policies such as lockdowns and social distancing. Just because of the seasonal changes the weather warms up,” said co-author Dr. Tom Smith. “Reduced fall and winter temperatures could make it easier for the virus to spread without policy intervention or behavior change” (https://bit.ly/3vedKKk).
