Contamination and washing of cloth #masks and risk of infection among hospital health workers in Vietnam: a post hoc analysis of a randomised controlled trial

In a previous randomised controlled trial (RCT) in hospital healthcare workers (HCWs), cloth masks resulted in a higher risk of respiratory infections compared with medical masks. This was the only published RCT of cloth masks at the time of the COVID-19 pandemic.. ..Viral contamination with rhinovirus was identified on both used medical and cloth masks. Most HCW (77% of daily washing) self-washed their masks by … Continue reading Contamination and washing of cloth #masks and risk of infection among hospital health workers in Vietnam: a post hoc analysis of a randomised controlled trial

#Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress

Key points In humans, hypohydration attenuates sweat secretion and attenuates whole‐body heat loss, probably to mitigate further fluid losses and thereby support blood pressure regulation. Recently, however, we demonstrated that the hypohydration‐mediated reduction in net whole‐body heat exchange (evaporative heat loss – dry heat gain) was blunted in middle‐aged compared to younger men during moderate exercise in dry heat; albeit, the underpinning mechanisms could not … Continue reading #Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress
