Poor sleep impacts risk of long-term cognitive decline in Hispanic/Latino adults

Poor sleep impacts the risk of long-term cognitive decline in Hispanic/Latino middle aged and older adults differently than it does in non-Hispanic adults, according to research led by University of Miami Miller School of Medicine neurology faculty and the largest long-term study of U.S. Hispanic/Latinos to date.

Non-droplet routes of SARS-CoV-2 transmission

In a recent review article published in the Science of The Total Environment journal, a group of Polish researchers discussed the different transmission routes of the severe acute respiratory coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease 2019 (COVID-19). In their work, the researchers focused on the extent of SARS-CoV-2 survival in the environment, particularly in sewages and contaminated surfaces.

Altered blood flow in the brain may cause symptoms of Parkinson's disease

Patients who suffer from REM sleep behavior disorder have altered blood flow in the brain, which can lead to a lack of oxygen in the brain tissue. In the long term, this may cause symptoms of Parkinson's disease. This is shown by research from Aarhus University and Aarhus University Hospital.

Pain monitoring technology can reduce intraoperative opioid consumption

A new study has shown that effective opioid-sparing anaesthesia with dexmedetomidine can be guided with NOL pain monitoring technology (Medasense, Israel). The study showed that the NOL monitor is able to detect the effect of dexmedetomidine on the patient's pain response and enable administration of less intraoperative opioids.

DEFINE: Trial designed to test repurposed treatments in patients with COVID-19

A team of scientists from the United Kingdom has designed an experimental medicine trial to evaluate the safety/tolerability, and efficacy profiles of a panel of candidate repurposed therapies in coronavirus disease 2019 (COVID-19) patients. A detailed outline of the trial is currently available on the medRxiv* preprint server.

Could an antiviral mouthwash using silver nanoparticles prevent COVID-19?

In a recent study by researchers in Mexico, Russia and Spain, silver nanoparticles (AgNPs) were found to inhibit SARS-CoV-2 in healthcare workers. They propose a non-pharmaceutical public health intervention consisting of mouthwash and nose rinse with an AgNPs solution to reduce morbidity among healthcare personnel exposed to the SARS-CoV-2 virus.
