COVID science-tall COVID brain fog found to be similar to ‘chemo brain’; Clip-on device shows promise in virus detection

by Nancy Lapido

Jan 12 () – The following is a summary of some recent studies on COVID-19. They include research that warrants further study to confirm the findings and that has not yet been substantiated by peer review.

Long COVID “brain fog” features with “chemo brain”

According to new research, the “brain fog” reported by some after COVID-19 bears striking similarity to a condition known as “chemo brain”—a mental illness some people have during and after cancer treatment. Clouds are felt.

People who had COVID-19 “often experienced neurological symptoms, including impairments in attention, concentration, information processing speed, and memory,” similar to patients with cognitive impairments related to cancer therapy, which have been shown to include brain swelling. Known for this, the researchers explained in a report posted Monday on biorxiv https://www.biorxiv.org/content/10.1101/2022.01.07.475453v1 prior to peer review. In the brains of patients who died of COVID-19, researchers found evidence of inflammation with high levels of inflammatory proteins, one of which, CCL11, is associated with impairments in nervous system health and cognitive function.

Among 63 patients with so-called prolonged COVID, researchers found high CCL11 levels in 48 with prolonged cognitive symptoms, but not in 15 without cognitive issues. They speculate that treatments that show promise for cognitive impairment related to cancer therapy may be helpful for COVID-19 patients with similar problems. But they will need to be tested exclusively for long-term COVID.

Experimental clip-on device detects virus particles in the air

A small experimental device designed to be attached to clothing may be able to tell whether a wearer has been exposed to SARS-CoV-2 particles in the air, the researchers said.

The device, called the Fresh Air Clip, continuously collects airborne aerosols, including virus-carrying droplets, on the surface of silicon, according to a report published Tuesday in Environmental Science and Technology Letters https://pubs.acs.org/doi/. complete/10.1021/acs.estlett.1c00877. After testing the device in laboratory experiments, the researchers distributed them to 62 volunteers, each of whom wore the monitor for five days. PCR analysis detected the coronavirus in five clips, four of which were worn by a restaurant server and an employee at a homeless shelter.

The researchers noted that more research is needed to confirm its effectiveness before the device can be sold commercially. But it could prove useful in “real-world high-risk settings,” improving early detection of potential cases and helping to identify high-risk indoor areas with high risk.

Researchers plan to reuse hospital-grade masks

Researchers believe a type of mask used by healthcare providers to protect themselves from the coronavirus could be recycled to increase supply.

Unlike cloth and surgical masks, N95 respirators are designed to achieve a very snug facial fit, with the sides forming a tight seal around the nose and mouth. At the start of the pandemic, a shortage of N95 masks forced personnel to re-use them or use masks that provided less protection. In a paper in the American Journal of Infection Control https://www.ajicjournal.org/article/S0196-6553(21)00741-0/fulltext, researchers report that masks can be safely re-recyclable with standard decontamination approaches. Can be sterilized contain vaporized hydrogen peroxide and still maintain their effectiveness for up to 25 cycles of reuse.

Successful, large-scale implementation of N95 respirator reprocessing will require significant coordination and logistical support to ensure disinfection and safety, he said. “It would be wise to plan now for ways to scale and translate this capability into smaller hospitals and resource-limited health care settings that could equally benefit from this type of personal protective equipment reprocessing in future disaster scenarios. Christina Yen of Beth Israel Deaconess Medical Center in Boston said in a press statement.
