The maximal oxygen uptake (VOmax) and maximal power output (P) are commonly used parameters to evaluate the endurance fitness status. A connection between exercise and the kynurenine pathway (KP), which describes the metabolism of unused tryptophan, has already been reported. However, a potential association of the KP with endurance fitness levels remains unknown.

Methods: One-hundred-twenty adolescents completed two bicycle spiroergometries within 14 days. One of the two tests was performed based on our institutional weight-adapted protocol (P0).
The aim of this study was to evaluate whether spiroergometry performance in adolescent alpine ski racers can predict later advancement to a professional career. Over 10 consecutive years, adolescent skiers of the regional Austrian Youth Skier Squad (local level) underwent annual medical examinations, including exhaustive bicycle spiroergometry. The performance was determined at fixed (2 and 4 mmol/l serum lactate) and individual (individual anaerobic threshold (IAT) and lactate equivalent (LAE)) thresholds.

The aim of this longitudinal study was to assess temporal changes in morbidity and mortality of patients with EA/TEF treated in a tertiary-level center, focusing on postoperative complications and their impact on long-term gastroesophageal function.
Methods: One hundred nine consecutive patients with EA/TEF born between 1975 and 2011 were followed for a median of 9.
Infections with adenoviruses are a common problem in the pediatric population. Normally asymptomatic to mild, those infections tend to take a more severe course in immunocompromised patients. 22q11 deletion syndrome (22q11DS) represents a common genetic disorder causing immunodeficiency from thymic hypoplasia or aplasia, heart defects, a characteristic facial appearance, and velopharyngeal dysfunction.

Children between 0 and 18 years of age presenting with injuries at the trauma outpatient in the Department of Pediatric Surgery in Graz and six participating hospitals in Austria were evaluated over a 2-year prospective survey. A total of 28,983 pediatric trauma cases were registered.

The figures for different areas and time periods are hardly comparable, because of differences in postmortem investigations and classification criteria. In 1992, the European Society for the Study and Prevention of Infant Deaths (ESPID) proposed a classification for any sudden and unexpected death in infancy.

The measurements were performed in a 400 kW single combustor rig at typical engine conditions of up to 0.8 MPa inlet pressure and 673 K inlet temperature.
