Effect of methylprednisolone treatment on COVID-19: An inverse probability of treatment weighting analysis.

Lorenzo Porta, Sih-Shiang Huang, Chen Wei et al. · 2022 · PLoS ONE

Objectives While corticosteroids have been hypothesized to exert protective benefits in patients infected with SARS-CoV-2, data remain mixed. This study sought to investigate the outcomes of methylprednisone administration in an Italian cohort of hospitalized patients with confirmed SARS-CoV-2 infection. Methods Patients with confirmatory testing for SARS-CoV-2 were retrospectively enrolled from a tertiary university hospital in Milan, Italy from March 1st to April 30th, 2020 and divided into two groups by administration of corticosteroids. Methylprednisolone was administered to patients not r

Is reading fiction associated with a higher mind-reading ability? Two conceptual replication studies in Japan

Yuka Takahashi, Toshiyuki Himichi, Ayumi Masuchi et al. · 2023 · PLoS ONE

Previous studies have revealed that reading fiction is associated with dispositional empathy and theory-of-mind abilities. Earlier studies established a correlation between fiction reading habits and the two measures of social cognition: trait fantasy (i.e., the tendency to transpose oneself into fictitious characters) and performance on the Reading the Mind in the Eyes Test (RMET; a test of the ability to identify others’ mental states based on their eyes). Recently, experimental studies have shown that brief exposure to fiction enhances RMET performance. Nevertheless, these studies have been

Genetic variants associated with sepsis-associated acute kidney injury.

Nicholas J Douville, Lisa Bastarache, Emily Bertucci-Richter et al. · 2024 · PLoS ONE

Background Kidney dysfunction is a common complication in septic patients. Studies have identified numerous risk factors for sepsis-associated acute kidney injury (S-AKI), yet there is wide variability in the incidence even among patients with similar risk factors, suggesting the presence of additional uncharacterized risk factors, including genetic differences. The expansion of biobanks, advances in genotyping, and standardized diagnostic criteria have enabled large-scale, hypothesis-generating studies into the genetic mechanisms underlying S-AKI. We hypothesize that the genetic pathway behin
