Corona virus

The vaccination campaign will still be long before decreeing the end of the covid-19 pandemic. While research continues to try to stem the damage and contagion, the Reuters reported a summary of some of the latest scientific studies done on the coronavirus.

Covid severity can be affected by the gut microbiome

Second a study conducted in Hong Kong and appeared in the journal Gut, the gut microbiome could influence the severity of Covid-19 and the extent of the immune response to the infection. “The composition of intestinal microorganisms (microbiota) in Covid-19 patients, very different from non-infected individuals, is related to the severity of the disease. Covid patients do not have some good bacteria known to regulate the immune system,” notes Siew Ng , of the Chinese University of Hong Kong, lead author of the study, “The abnormal gut microbiota (dysbiosis) in patients with Covid persists after elimination of the virus.” Researchers led by Siew Ng examined blood and stool samples from 100 adults with a mean age of 36 who were hospitalized with covid, compared to those of 78 adults, with a mean age of 45, without the infection who were participating in a pre-pandemic microbiome study. the composition of the gut microbiome was statistically significantly altered in patients with Covid-19.

The pandemic has an impact on the mental health of ICU workers

Almost half of the staff working in intensive care units in England suffer from anxiety, depression or post-traumatic stress disorder, according to Occupational Medicine. The studio it was conducted in June and July, before Britain began experiencing the latest wave of hospitalizations. Of the more than 700 healthcare workers in nine ICUs, 45% reached the threshold of probable clinical significance for at least one of the four mental disorders: severe depression (6%), post-traumatic stress disorder (40%), severe anxiety (11%) or problems with alcohol (7%). More than one in eight reported frequent thoughts of harming or killing themselves in the previous two weeks. According to the researchers, this not only impairs their quality of life, but likely also impairs their ability to work effectively.

Cooling vests help nurses in covid wards endure personal protective equipment

Nurses in covid wards who wear cooling vests under their personal protective equipment are better able to withstand heat during shifts, a study says. For the Research, 17 nurses were examined on two different days: one wearing the vests and one without. In both cases, participants ingested an electronic capsule that provides a continuous reading of core body temperature. The vests led to a slight improvement in body temperature but a significant improvement in the feeling of being too hot. According to the results reported in Temperature magazine, only 18% of nurses reported thermal discomfort and 35% reported a slightly warm thermal sensation at the end of the day with the vest. On the day without a vest the percentages were 81% and 94%.

Diabetes adds to the covid risks for black patients

A new studio shows that black type 1 diabetes patients with covid face a particularly high risk of a dangerous diabetes complication known as ketoacidosis. Type 1 diabetes usually develops in children or young adults, who need daily insulin injections to survive. The researchers looked at 180 patients from across the United States with type 1 diabetes and covid: 31% were black, 26% Hispanic. Black patients were nearly four times as likely to develop diabetic ketoacidosis than white patients. As reported in the Journal of Clinical Endocrinology and Metabolism, Hispanics had a slightly higher risk than white patients.
