Abstract

The objective of this study was to assess intra- and inter-evaluator reliability and validity of ventilatory threshold (VT) determination in children. At the age of 6-12 yr, 35 children born prematurely and 20 controls born at term performed an incremental continuous cycling task until volitional fatigue. Fifteen-second averages of VE/VO2, VE/VCO2, and respiratory exchange ratio were plotted 1) over time (X-time) and 2) over VO2 (X-VO2). VCO2 was plotted over VO2 only (X-VO2). Two experienced evaluators, blind to the identity of plots, independently assessed VT from X-time and X-VO2 plots on two occasions, 6 wk apart. Thus, for each of the 55 subjects, four VT values were expected from X-time plots and four from X-VO2 plots (2 evaluators, 2 occasions). VT expressed as VO2 in mL x min(-1) could be determined by both evaluators on both occasions in 40/55 children from X-time and in 45/55 children from X-VO2. VT was significantly different between evaluators for X-time plots. Using X-time plots, intraevaluator ICC were 0.88 and 0.98 and interevaluator ICC were 0.82 and 0.79. The respective values for X-VO2 plots were 0.94 and 0.95, and 0.96 and 0.92. Intra- and inter-evaluator reliability of VT determinations tended to be slightly...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.
