Multidetector Computed Tomography Criteria of Operative Treatment of Diastasis Recti Abdominis

open access: yesGalician Medical Journal, 2016
We introduce an experience of surgical treatment of 92 patients with diastasis recti abdominis (DRA). A high efficiency of multidetector computed tomography (MDCT) in this category of patients is shown. There were 3 degrees of DRA distinguished depending

Covid-19 mobility restrictions: impacts on urban air quality and health

open access: yesBuildings & Cities, 2021
In 2020, Covid-19-related mobility restrictions resulted in the most extensive human-made air-quality changes ever recorded. The changes in mobility are quantified in terms of outdoor air pollution (concentrations of PM2.5 and NO2) and the associated ...
