VITAMIN D, ACUTE RESPIRATORY INFECTIONS, AND COVID-19: THE CURSE OF SMALL-SIZE RANDOMISED TRIALS. A CRITICAL REVIEW WITH META-ANALYSIS OF RANDOMISED TRIALS.

BackgroundRandomised trials conducted from 2006 to 2021 indicated that vitamin D supplementation (VDS) was able to prevent severe COVID-19 and acute respiratory infections (ARI).However, larger randomised trials published in 2022 did not confirm the health benefits of VDS in COVID-19 patients.ObjectiveTo examine through a systematic review with met

Abstract Background Staphylococcus shinii appears as an umbrella species encompassing several strains of Staphylococcus pseudoxylosus and Staphylococcus xylosus.Given its phylogenetic closeness to S.xylosus, S.shinii can be found in similar ecological niches, including the microbiota of fermented meats where the species may contribute to colour and

Based on the energy atmas scarab storage problems for solar energy utilization and the advantages of spiral groove tube heat exchanger, spiral groove tubes are used in the solar energy phase change heat storage, with numerical simulation of the thermal storage process of heat reservoir.Firstly, the simulation method and the reliability of the used

Grid formation inspection is the future development trend of grid inspection.Aim to the robust control problem of multi-agent grid inspection system in 14b-ca0013dx complex environment, this paper proposes a formation control algorithm with prescribed performance.The dynamic model of follower distance error is given in the leader-follower framework
