Diagnostic Accuracy of Breath Tests to Detect Pulmonary Tuberculosis: A Systematic Review.
Lung
January 2025
Department of Medicine, National University Hospital, NUHS Tower Block, Level 10, 1E Kent Ridge Road, Singapore, 119228, Singapore.
Purpose: Tuberculosis (TB) is a highly contagious infection and one of the world's leading causes of death from a single infectious agent. Currently, TB diagnosis can be established via mycobacterial cultures, Acid Fast Bacilli smear and molecular studies. In the ever-evolving landscape of medical advancements, breath tests have shown considerable promise.

Mycobacterium marinum is a major pathogen in aquaculture, posing a substantial threat to the health and sustainability of tongue sole (Cynoglossus semilaevis) farming. This study investigated the genetic basis of immune response in tongue sole by comparing transcriptome profiles of liver and spleen tissues from symptomatic (susceptible) and healthy (resistant) individuals during a natural M. marinum outbreak.

The objective of this study was to evaluate the flavor profiles of water-boiled pork meatballs at different ultrasonic powers (0, 150, 300, 450, 600, and 750 W) using solid-phase microextraction gas chromatography-mass spectrometry (SPME-GC-MS) combined with electronic nose (E-nose). A total of 36 volatile compounds were determined by SPME-GC-MS, including alcohols, aromatic hydrocarbons, aldehydes, terpenes, alkanes, phenols, ketones, and other. With the appropriate ultrasound treatment, the type and relative content of volatile compounds were significantly increased (P < 0.

Natural olfactory systems possess remarkable sensitivity and precision beyond what is currently achievable by engineered gas sensors. Unlike their artificial counterparts, noses are capable of distinguishing scents associated with mixtures of volatile molecules in complex, typically fluctuating environments and can adapt to changes. This perspective examines the multifaceted biological principles that provide olfactory systems their discriminatory prowess, and how these ideas can be ported to the design of electronic noses for substantial improvements in performance across metrics such as sensitivity and ability to speciate chemical mixtures.
