Covid-19 patients during and after treatment often have problems with cognitive changes, called “brain fog”.
According to a new study from the US, the phenomenon of “brain fog” appears in some Covid-19 patients after treatment. This shows striking similarities to the condition “chemo brain” – cognitive changes that often occur during and after cancer treatment.
Among 63 patients with Covid-19, the researchers found high levels of CCL11 (eosinophil chemotaxis protein) in 48 people with persistent symptoms of cognitive changes. However, the remaining 15 also had cognitive problems. The team speculates that treatments for cognitive decline in cancer patients could be helpful for Covid-19 patients with similar problems.
The researchers also put a small experimental device attached to the garment, which can detect whether the wearer has been exposed to airborne SARS-CoV-2 virus particles.
According to a report published in the journal Environmental Science & Technology Letters, the device, called the Fresh Air Clip, continuously collects airborne aerosols, including virus-carrying droplets on silicon surfaces. After testing the device, the researchers distributed it to 62 volunteers, each of whom wore the device for five days. PCR analysis from the device detected the Corona virus on 5 of them.
Before the initial test results, the scientists note that more research is needed to confirm the effectiveness of the device before it goes on sale. This device proves to be useful in the current epidemic context, helping to improve the ability to detect infections early and identify outbreaks.
Besides the above invention, the researchers also plan to reuse medical masks. They believe the masks doctors often wear at the hospital can be reprocessed to increase supply.
Unlike cloth masks and surgical masks, N95 respirators are designed to fit the face, sealing around the nose and mouth. Early in the pandemic, a shortage of N95 masks forced healthcare workers to reuse them or use masks with less protection.
In an article in the American Journal of Infection Control, researchers suggest that masks can be safely re-sterilized using standard decontamination methods involving vaporized hydrogen peroxide and still remain effective. up to 25 reuse cycles.
They said that a successful, large-scale implementation of the N95 respirator mask recycling process requires significant coordination and logistical support in the process of sterilization and safety.
“It’s best to plan now to find ways to scale up to reach small hospitals and resource-constrained healthcare facilities. Recycling personal protective equipment is very helpful. in future disaster situations”, Dr Christina Yen, Beth Israel Deaconess Medical Center (Boston, USA) said.
