An extended high ‐frequency ultrasound protocol for detection of vessel wall inflammation
ConclusionAn extended ultrasound protocol for central neck and leg arteries could be of value for diagnosis of arteritis. In case of atypical vessel wall inflammation, other main diagnoses should be considered. (Source: Clinical Physiology and Functional Imaging)

Relation of oxygen uptake to work rate in prepubertal healthy children – reference for VO2/W‐slope and effect on cardiorespiratory fitness assessment
ConclusionThe reference values for VO2/W‐slope among healthy prepubertal children were similar to those published for adults and among adolescents. Estimated and measured VO2PEAK should not be considered to be interchangeable because of the variation in the relationship between VO2 and W. On other hand, variation in the relationship between VO2 and W enables that VO2/W‐slope can be used as a diagnostic tool. (Source: Clinical Physiology and Functional Imaging)

A reassessment of the blood –brain barrier transport of large neutral amino acids during acute systemic inflammation in humans
Summary We reassessed data from a previous study on the transcerebral net exchange of large neutral amino acids (LNAAs) using a novel mathematical model of blood–brain barrier (BBB) transport. The study included twelve healthy volunteers who received a 4‐h intravenous lipopolysaccharide (LPS) infusion (total dose: 0·3 ng/kg), a human experimental model of the systemic inflammatory response during the early stages of sepsis. Cerebral blood flow and arterial‐to‐jugular venous LNAA concentrations were measured prior to and after LPS, and the BBB transport and brain extracellular concentrations of LNAAs were calculat...

Relationship between ultrasound muscle thickness and MRI ‐measured muscle cross‐sectional area in the forearm: a pilot study
Summary Previous studies have investigated the relationship between ultrasound‐measured muscle thickness (MT) and individual muscle cross‐sectional area (CSA); however, the forearm muscle had not yet been studied. The purpose of this study was to examine the relationship between forearm MT by ultrasound and the muscle CSA of the forearm obtained by magnetic resonance imaging (MRI). Ten young and middle‐aged adults had both ultrasound and MRI measurements at 30% the distance from the styloid process of the ulna to the head of the radius. Handgrip strength (HGS) was also measured. Strong correlations (P<0·001) were...

Physiological measures in participants with chronic fatigue syndrome, multiple sclerosis and healthy controls following repeated exercise: a pilot study
ConclusionThese results suggest that exercise exhibits a different physiological response in MS and CFS/ME, demonstrating repeated cardiovascular exercise testing as a valid measure for differentiating between fatigue conditions. (Source: Clinical Physiology and Functional Imaging)

Eucapnic voluntary hyperventilation test in children
ConclusionThe EVH test was successful in the 10‐16‐year‐old children having participated in the study and the test was well tolerated. Through the study, it was possible to provoke both dysfunctional breathing disorder and bronchoconstriction in the symptomatic patients. Based on the pilot study, EVH test seems to be usable in the diagnostics of pediatric exercise‐induced dyspnea but larger studies are warranted to confirm our preliminary findings.
