Summary: The inclusion of new target compounds and the use of prior knowledge obtained from anti-doping data can improve the detection of doping practices with endogenous anabolic androgenic steroids. This is particularly effective for individuals with low levels of biomarkers excreted in urine.

Summary: The haematological module of the athlete biological passport (ABP) is a valuable tool in anti-doping efforts, but there are many factors that can potentially confound the results and affect the interpretation of individual athlete profiles. Further research is needed to improve the objective sensitivity of the ABP.

Summary: This study investigated the possible changes in the markers of the steroidal module of the athlete biological passport, taking into account athletes' declaration or non-declaration of thyroid hormone supplementation. Concentrations of various biomarkers were calculated using gas chromatography-tandem mass spectrometry, and ratios between these biomarkers were estimated. The results showed significant differences in marker concentrations and ratios between the groups declaring and not-declaring thyroid hormone supplementation. A controlled study confirmed these observations, particularly in the female group. The findings suggest that the interpretation of steroid markers in the athlete biological passport should consider thyroid hormone administrations.

Summary: This study investigated the impact of low-volume blood withdrawal on hematological biomarkers considered for anti-doping purposes. Blood withdrawal led to a significant decrease in hemoglobin mass and red blood cell volume at D + 7. However, hemoglobin concentration increased significantly at D + 21. Ferritin was consistently downregulated following blood withdrawal. These results highlight the challenge of monitoring hematological variables for detecting low-volume blood withdrawal.

Summary: This study provided hematological results in the context of the Athlete Biological Passport (ABP) from an EPO administration study. Significant changes were observed in various blood parameters in the EPO group compared to baseline, while no significant changes were found in the placebo group. From the ABP perspective, a high occurrence of atypical passport findings (ATPF) was observed in the EPO group, particularly during the boosting and initial washout phases.

Summary: The athlete biological passport uses blood variables to detect blood doping. A study comparing the XN and XT/XE series of blood analyzers found a bias towards higher RET% values on the Sysmex XN instruments. The bias was proportional and slightly higher than previously observed across most RET% values, suggesting a model for comparing data across the two technologies.

Summary: The study aimed to understand the perceptions of skilled volleyball players on the influences of parents, coaches, and peers on their sport development and performance. Results showed that significant others had different impacts on players based on their expertise level, with highly skilled players valuing moderate parental involvement and demanding coaches, while less skilled players preferred excessive parental involvement.

Summary: This study explores the different types of support and support providers for male cricket players at different skill levels. The results show that mothers and fathers primarily provide financial and emotional support, while mentors and siblings play a more frequent role in supporting elite players.

Summary: The Athlete Biological Passport (ABP) is an indirect anti-doping approach that monitors blood and urine samples to detect possible use of prohibited substances or methods. New biomarkers are being developed to enhance the sensitivity and specificity of the ABP. In addition to improving analytical sensitivity, machine learning methods are expected to facilitate the interpretation of biological profiles and promote anti-doping efforts.

Summary: A vaccination passport is a document that provides proof of vaccination and certifies protection from illness, allowing holders the privilege of traveling freely between countries without restrictions. However, implementing vaccination passports involves various ethical, legal, and data security concerns that need to be addressed.

Summary: This research aimed to investigate the association between attention, working-memory control and capacity, and sport performance across different levels of athletic expertise. The results showed that working-memory control and capacity mediate the relationship between attention and sport performance, with larger effects observed in those with higher athletic expertise.

Summary: The employment rate and organizational interest in high-skilled professionals are important drivers for universities to improve the qualifications of college students. By investigating the sectors of employment pursued by forestry engineering graduates and surveying companies affiliated with the Forest Science and Research Institute (IPEF), it was found that there is a significant potential for employment in the forestry sector, with noticeable growth in the past five years. This growth is attributed to market demand and changes in action plans.
