The overall metabolic state of an individual is reflected by emitted volatile organic
compounds (VOCs), which are gaseous carbon-based chemicals. In this review, we will …

Early detection of late-onset sepsis (LOS) in preterm infants is crucial since timely treatment
initiation is a key prognostic factor. We hypothesized that fecal volatile organic compounds …

VOC analysis of small molecules is a facile method for assessing stool and urine. Gut
chemistry is exceedingly complex and the results of VOC analysis offer a simplified picture of …

Breath analysis is a young field of research with its roots in antiquity. Antoine Lavoisier
discovered carbon dioxide in exhaled breath during the period 1777–1783, Wilhelm (Vilém) …

Volatile organic compounds (VOCs) are ubiquitous in the environment, originating from
many different natural and anthropogenic sources, including tobacco smoke. Long-term …

ABSTRACT A rapid headspace gas chromatography tandem mass spectrometric (HS-
GC/MS) method was established for the analysis of volatile fatty acids (VFAs) in the feces …

Endoscopic evaluation is mandatory in establishing the diagnosis of pediatric inflammatory
bowel disease (IBD), but unfortunately carries a high burden on patients. Volatile organic …

The analysis of the human volatilome can be successfully used for rapid and non-invasive
diagnostics of gastrointestinal diseases. However, the introduction of techniques based on …

Organic acids (OAs) play important roles in a variety of intracellular metabolic pathways,
such as the tricarboxylic acid cycle, fatty acid oxidation, glycolysis. The accurate detection of …

Metabolomics is a well-established field in fundamental clinical research with applications in
different human body fluids. However, metabolomic investigations in feces are currently an …
