Environmental PM Exposure: An Ignored Factor Associated with Blood Cadmium Level in Hemodialysis Patients.

Background: The negative impacts of particulate matter with an aerodynamic diameter of 2.5 μm or less (PM) are well known. Patients undergoing maintenance hemodialysis (HD) have significantly higher blood cadmium levels (BCLs) than healthy individuals.

Barriers to early detection: Insurance denials for breast MRI screening in women with germline BRCA1/2 mutations.

Objectives: Women with germline BRCA1/2 pathogenic variants (gBRCA1/2) are recommended to undergo annual breast MRI and mammography. Our objective was to describe the frequency of insurance denials for annual breast MRIs in women with gBRCA1/2 and determine denial trends.

Methods: Women with gBRCA1/2 following in a high-risk breast cancer clinic with breast MRIs ordered from 2020 to 2021 were identified and cross-referenced with a database of insurance denials.

Statin Monotherapy Not Inferior to Aspirin or Combined Aspirin and Statins Reducing the Incidences of Cirrhosis, HCC, and Mortality in MAFLD/MASH Patients: A Population Cohort Study.

Purpose: Metabolic dysfunction-associated fatty liver disease (MAFLD) and metabolic dysfunction-associated steatohepatitis (MASH) pose significant risks for liver cirrhosis and hepatocellular carcinoma (HCC). Daily aspirin and statins could reduce HCC in patients with MAFLD/MASH. We aimed to clarify whether combined aspirin and statins exert a synergistic effect on prevention of cirrhosis and HCC in patients with MAFLD/MASH.

Beyond metabolic messengers: Bile acids and TGR5 as pharmacotherapeutic intervention for psychiatric disorders.

Psychiatric disorders pose a significant global health challenge, exacerbated by the COVID-19 pandemic and insufficiently addressed by the current treatments. This review explores the emerging role of bile acids and the TGR5 receptor in the pathophysiology of psychiatric conditions, emphasizing their signaling within the gut-brain axis. We detail the synthesis and systemic functions of bile acids, their transformation by gut microbiota, and their impact across various neuropsychiatric disorders, including major depressive disorder, general anxiety disorder, schizophrenia, autism spectrum disorder, and bipolar disorder.

Signatures of lower respiratory tract microbiome in children with severe community-acquired pneumonia using shotgun metagenomic sequencing.

Background: Severe community-acquired pneumonia was associated with high morbidity and mortality in children. However, species-level microbiome of lower airway was sparse, and we used shotgun metagenomic next-generation sequencing to explore microbial signatures.

Methods: We conducted a prospective cohort study to recruit children under 18 who required admission to an intensive care unit for community-acquired pneumonia between December 2019 and February 2022.
