Real-world effectiveness of mepolizumab in Japanese asthma patients with diverse backgrounds: Improvements in rhinosinusitis imaging (J-Real-Mepo).

Background: Although randomized controlled trials (RCT) have demonstrated the efficacy of mepolizumab for asthma, they have excluded certain patient subgroups. To bridge the gap between RCT and real-world practice, the effectiveness of mepolizumab in a diverse population, including those potentially excluded from RCT, was assessed. Its effects on imaging findings and symptoms of chronic rhinosinusitis (CRS) with asthma were also assessed.

Duration of infectious virus shedding of SARS-CoV-2 Omicron variant among immunocompromised patients.

Objective: The duration of viral shedding and criteria for de-isolation in the hospital among immunocompromised patients with coronavirus disease 2019 (COVID-19) remain unclear. This study aimed to evaluate viral shedding duration in immunocompromised patients infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2.

Methods: A prospective cohort study was performed at 2 tertiary medical centers in Japan during the Omicron epidemic waves from July 2022 to January 2023.

Treatment of Crohn's Disease With Infliximab and Subsequent Development of Takayasu's Arteritis.

A 23-year-old man was diagnosed with Crohn's disease (CD) of the large intestine after colonoscopy revealed longitudinal ulcers, and pathology revealed non-caseating epithelioid cell granulomas and anal fistulas. The CD relapsed, and therefore prednisolone (PSL) and infliximab (IFX) treatment was initiated. The PSL was gradually tapered.

Evaluation of rewarding effects of nitazene analogs: results from conditioned place preference tests and in vivo microdialysis experiments in mice.

In illicit drug markets, the most recently expanding new synthetic opioid subclass is benzimidazoles, also known as nitazenes, which were originally developed as analgesics in the 1950s. The emergence of this classical, potent drug family has attracted extensive research interest in the field of forensic toxicology; however, information on their psychological and physical dependence is very limited. Herein, we evaluated the rewarding effects of four nitazene analogs using a battery of in vivo experiments, with a positive control drug (isotonitazene).
