Is it COVID-19 or the flu? New sensor could tell you in 10 seconds

Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu — at much lower levels and much more quickly than conventional tests for either.

Trial By Error: A Stupid Study of Exercise for Long Covid Patients With Post-Exertional Symptom Exacerbation

By David Tuller, DrPH The Journal of Medical Virology has just published a study called “Effect of using a structured pacing protocol on post-exertional symptom exacerbation and health status in a longitudinal cohort with the post-COVID-19 syndrome.” The investigators are from the University of Leeds and the Leeds Community Healthcare NHS Trust. Post-COVID-19 syndrome (PCS)… Continue reading Trial By Error: A Stupid Study of Exercise for Long Covid Patients With Post-Exertional Symptom Exacerbation

Small studies of 40-hertz sensory stimulation confirm safety, suggest Alzheimer’s benefits

AI SummaryEarly-stage clinical studies have found that 40-hertz sensory stimulation was well-tolerated, with no serious adverse effects and produced neurological and behavioral benefits among participants with Alzheimer’s disease. The studies are preliminary and more extensive research is needed to determine the efficacy of 40-hertz sensory stimulation as a potential therapeutic for Alzheimer’s.A pair of early-stage… Continue reading Small studies of 40-hertz sensory stimulation confirm safety, suggest Alzheimer’s benefits

“Paxlovid Rebound” Is Just COVID Rebound

by Gertrud U. Rey The antiviral drug Paxlovid is highly effective at inhibiting SARS-CoV-2 replication and reducing symptoms associated with COVID-19. Nevertheless, there have recently been numerous reports of recurrence of positive tests and symptoms after completing treatment with Paxlovid, leading some to infer that the drug triggers the recurrence. Is this inference actually correct,… Continue reading “Paxlovid Rebound” Is Just COVID Rebound

Are Covid-19 “comas” signs of a protective hibernation state?

AI SummaryMany Covid-19 patients who have been treated with mechanical ventilation are slow to regain consciousness even after being taken off sedation, and a new study suggests that this could be due to a hibernation-like state induced by the brain to protect cells during periods of oxygen scarcity. This state has been observed in other… Continue reading Are Covid-19 “comas” signs of a protective hibernation state?
