The present study was performed to determine the variations of breath acetone concentrations with age, gender and body-mass index (BMI). Previous investigations were based on a relatively small cohort subjects (see Turner et al 2006 Physiol. Meas. 27 321-37). Since exhaled analysis is affected by considerable variation, larger studies are needed get reliable information about correlation volatiles in when compared BMI.

Breath analysis for the purpose of non-invasive diagnosis lung cancer has yielded numerous candidate compounds with still questionable clinical relevance. To arrive at suitable volatile organic our approach combined different sources: isolated tumor samples compared to healthy tissues, and exhaled breath from patients controls. Candidate were further substances previously identified in comparison transformed normal epithelial cell lines. For human studies, a sampling device was developed...

Abstract Objectives Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections cause disease 2019 (COVID-19) and induce a specific antibody response. Serological assays detecting IgG against the receptor binding domain (RBD) of spike (S) protein are useful to monitor immune response after infection or vaccination. The objective our study was evaluate clinical performance Siemens SARS-CoV-2 (sCOVG) assay. Methods Sensitivity specificity sCOVG test were evaluated on 178 patients...

Global healthcare systems are challenged by the COVID-19 pandemic. There is a need to optimize allocation of treatment and resources in intensive care, as clinically established risk assessments such SOFA APACHE II scores show only limited performance for predicting survival severely ill patients. Additional tools also needed monitor treatment, including experimental therapies clinical trials. Comprehensively capturing human physiology, we speculated that proteomics combination with new...
