The lung environment harbours a community of microbes that play a significant role in health and disease, including innate protection against pathogenic microorganisms. Infection with Mycobacterium tuberculosis, psychological stress associated with the tuberculosis (TB) disease, and the metabolites from the rifampicin treatment regimen have been reported to induce hyperglycemia and consequently type 2 diabetes mellitus (T2DM) in individuals not previously diabetic. The high glucose concentration is proposed to alter the composition of the lung microbiota and airway homeostasis, exerting an influence on TB disease and treatment outcomes.

Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder marked by repeated episodes of partial or complete upper airway obstruction during sleep, which leads to intermittent hypoxia and fragmented sleep. These disruptions negatively impact cardiovascular health, metabolic function, and overall quality of life. Obesity is a major modifiable risk factor for OSA, as it contributes to both anatomical and physiological mechanisms that increase the likelihood of airway collapse during sleep.

Overcrowding in emergency departments (EDs) is a global challenge, leading to prolonged waiting times and adverse patient outcomes. Telemedicine has emerged as a promising solution, enabling remote consultation, triage, and real-time specialist input. Despite its growing application, limited systematic research exists on its specific role in ED triage and care.

Background: In COPD, the balance between matrix metalloproteinases (MMPs) and their natural inhibitors [tissue inhibitors of metalloproteinases (TIMPs)] is shifted towards excessive degradation, reflected in bronchoalveolar lavage (BAL) as increased MMP concentrations. Because of their critical role in lung homeostasis, MMP activity is tightly regulated, but to what extent this regulation occurs through epigenetic mechanisms remains unknown.
Methods: To explore the interplay between MMPs, TIMPs, and DNA methylation (DNAm) we (1) analysed MMP-9, -12, and TIMP-1 concentrations in BAL fluid, and profiled DNAm in BAL cells from 18 COPD and 30 control subjects, (2) estimated protein-COPD relationships using multivariable regression, (3) identified protein quantitative trait methylation loci (pQTMs) with COPD as a potential modifier in a separate interaction model, and (4) integrated significant interactions with a previous COPD GWAS meta-analysis.

Objective: Determine if a flexed-neck posture during flexible nasolaryngoscopy (FNL) improves visualization of the subglottis.
Study Design: Retrospective review of children undergoing FNL in the neutral (FNL) and flexed-neck (FN-FNL) positions.
Setting: Tertiary children's hospital.
