Effectiveness of Oral Prophylactic Antibiotics for Diagnostic Bronchoscopy: A Nationwide Database Study.
Ann Am Thorac Soc
January 2025
The University of Tokyo, Department of Clinical Epidemiology and Health Economics, Bunkyo-ku, Tokyo, Japan.
Rationale: Although the guidelines generally omit routine antibiotic prophylaxis for diagnostic bronchoscopy, this recommendation is primarily based on studies with relatively small sample sizes conducted at single institutions. Moreover, the applicability of recent technical and procedural advancements to these guidelines remains uncertain.
Objectives: To evaluate whether oral prophylactic antibiotic administration for diagnostic bronchoscopy reduces post-bronchoscopy infections among non-infectious diseases in the current setting.
Single-Cell Multi-Omics Profiling of Immune Cells Isolated from Atherosclerotic Plaques in Male ApoE Knockout Mice Exposed to Arsenic.
Environ Health Perspect
January 2025
Division of Experimental Medicine, Department of Medicine, McGill University, Montréal, Canada.
Background: Millions worldwide are exposed to elevated levels of arsenic that significantly increase their risk of developing atherosclerosis, a pathology primarily driven by immune cells. While the impact of arsenic on immune cell populations in atherosclerotic plaques has been broadly characterized, cellular heterogeneity is a substantial barrier to in-depth examinations of the cellular dynamics for varying immune cell populations.
Objectives: This study aimed to conduct single-cell multi-omics profiling of atherosclerotic plaques in apolipoprotein E knockout () mice to elucidate transcriptomic and epigenetic changes in immune cells induced by arsenic exposure.
Highly multiplexed spatial transcriptomics in bacteria.
Science
January 2025
Program in Cellular and Molecular Medicine, Boston Children's Hospital, Boston, MA, USA.
Single-cell decisions made in complex environments underlie many bacterial phenomena. Image-based transcriptomics approaches offer an avenue to study such behaviors, yet these approaches have been hindered by the massive density of bacterial messenger RNA. To overcome this challenge, we combined 1000-fold volumetric expansion with multiplexed error-robust fluorescence in situ hybridization (MERFISH) to create bacterial-MERFISH.

PLoS Med
January 2025
Division of Psychiatry, University College London, London, United Kingdom.
Background: There is limited and conflicting evidence on the comparative cardiometabolic safety and effectiveness of aripiprazole in the management of severe mental illness. We investigated the hypothesis that aripiprazole has a favourable cardiometabolic profile, but similar effectiveness when compared to olanzapine, quetiapine, and risperidone.
Methods And Findings: We conducted an observational emulation of a head-to-head trial of aripiprazole versus olanzapine, quetiapine, and risperidone in UK primary care using data from the Clinical Practice Research Datalink.
Construction of an lncRNA-mediated ceRNA network to investigate the inflammatory regulatory mechanisms of ischemic stroke.
PLoS One
January 2025
Department of Biochemistry, College of Medicine, Shihezi University, Shihezi, Xinjiang, China.
Long non-coding RNAs (lncRNAs) are among the most abundant types of non-coding RNAs in the genome and exhibit particularly high expression levels in the brain, where they play crucial roles in various neurophysiological and neuropathological processes. Although ischemic stroke is a complex multifactorial disease, the involvement of brain-derived lncRNAs in its intricate regulatory networks remains inadequately understood. In this study, we established a cerebral ischemia-reperfusion injury model using middle cerebral artery occlusion (MCAO) in male Sprague-Dawley rats.
