[Recommendations for training courses in bronchoscopy - update 2024].

Bronchoscopy courses should be an integral part of bronchoscopy training. Course graduates should be familiar with the indications, prerequisites and technical possibilities of bronchoscopy. In addition to theoretical content, practical bronchoscopic skills are taught and trained in small supervised groups using various methods of simulation-based bronchoscopy training.

Effects of weight loss and exercise on apelin serum concentrations and adipose tissue expression in human obesity.

Objective: Apelin is an adipokine which plays a role in the regulation of glucose homeostasis and may contribute to the link between increased adipose tissue mass and obesity related metabolic diseases. Here we investigate the role of omental and subcutaneous (SC) adipose tissue apelin and its receptor APJ mRNA expression in human obesity and test the hypothesis that changes in circulating apelin are associated with reduced fat mass in three weight loss intervention studies.

Methods: Apelin serum concentration was measured in 740 individuals in a cross-sectional (n = 629) study including a subgroup (n = 161) for which omental and SC apelin mRNA expression has been analyzed and in three interventions: 12 weeks exercise (n = 60), 6 months calorie-restricted diet (n = 19), 12 months after bariatric surgery (n = 32).

Long-term exercise training decreases interleukin-6 (IL-6) serum levels in subjects with impaired glucose tolerance: effect of the -174G/C variant in IL-6 gene.

Objective: Exercise training has been shown to have anti-inflammatory effects in patients with type 2 diabetes. Changes in interleukin-6 (IL-6) serum concentrations in response to training could contribute to these beneficial effects. However, there are heterogeneous data on whether circulating IL-6 is altered by exercise training.
