Abstract Despite constituting a widespread and significant environmental change, understanding of artificial nighttime skyglow is extremely limited. Until now, published monitoring studies have been local or regional in scope typically short duration. In this first major international compilation data we answer several key questions about properties. Skyglow observed to vary over four orders magnitude, range hundreds times larger than was the case before light. Nearly all study sites were...

Anal and urethral samples from confirmed cases of monkeypox were screened for virus (MPXV) by real-time PCR. Isolation the was subsequently attempted in cell culture. Actively-replicating demonstrated 13 18 11 15 PCR-positive anal swabs, respectively, collected within 7 days symptoms onset. Two asymptomatic secondary had detectable MPXV genetic material secretion one, successfully isolated, supporting a potential sexual transmission hypothesis.

Recent studies have highlighted the prognostic value of easily accessible inflammatory markers, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte (PLR) for predicting severe outcomes in patients affected by Coronavirus disease 2019 (COVID-19). Our study validates NLR PLR cut-off values from a prior cohort at IRCCS Policlinico San Matteo (OSM) Pavia, Italy, across two new cohorts different hospitals. This aims to enhance generalizability these indicators. In this retrospective...
