Fatigue amongst anaesthesiology and intensive care trainees in Europe: A matter of concern.

Background: There is a growing awareness of the effects of fatigue on trainee wellbeing and health. Trainees in anaesthesiology and intensive care work long hours, switching work schedules frequently with insufficient rest. This may have unwanted long-term effects on mental and physical health and emotional well being, resulting in burnout and affecting patient safety.

Comprehensive Zebrafish Water Tank Experiment for Metabolic Studies of Testolactone.

Testolactone is a potent steroid aromatase (CYP19A1) inhibitor, and its main effect is a reduction in estradiol and estrone and an increase in testosterone and androstenedione levels. In this work, we evaluated a zebrafish water tank (ZWT) as a model to investigate testolactone biotransformation and the possibility to increase knowledge regarding the applicability of the ZWT on steroid hormone elimination research, as well as on the impact of steroid hormones on the endogenous metabolism of zebrafish. High-resolution mass spectrometry combined with SIEVE software was used to discriminate the peaks of interest based on significant changes in the relative signal intensity of the values between different ZWT experiments.

Development of a liquid chromatography Q Exactive high resolution mass spectrometry method by the Box-Behnken design for the investigation of sibutramine urinary metabolites.

Sibutramine is cited by the World Anti-Doping Agency as a stimulant. According to the literature, sibutramine is extensively metabolized into N-desmethyl-sibutramine (M1), N-bisdesmethyl-sibutramine (M2) and monohydroxy derivatives of M1 and M2. Therefore, it is important to verify new sibutramine metabolites through current analytical methodologies, such as liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS).

Anaesthesiology trainees and their needs: a Romanian perspective. Results from a European survey.

Anaesthesiology training is going through continuous transformations worldwide. Recent data from a European Survey on anaesthesiology postgraduate trainees and their concerns have been published for the first time, following an initiative by the European Society of Anaesthesiology. Among the responders of this survey, 10.

Is zebrafish (Danio rerio) a tool for human-like metabolism study?

One of the greatest challenges in anti-doping science is the large number of substances available and the difficulty in finding the best analytical targets to detect their misuse. Therefore, metabolism studies involving prohibited substances are fundamental. However, metabolism studies in humans could face an important ethical bottleneck, especially for non-approved substances.
