Rotating night work, lifestyle factors, obesity and promoter methylation in <i>BRCA1</i> and <i>BRCA2</i> genes among nurses and midwives

<div><p>Some recent evidence suggests that environmental and lifestyle factors may modify DNA methylation. We hypothesized that rotating night work and several modifiable factors may be associated with the methylation of the promoter regions within two tumor suppressor and DNA repair genes: <i>BRCA1</i> and <i>BRCA2</i>. The methylation status of <i>BRCA1</i> and <i>BRCA2</i> was determined via qMSP reactions using DNA samples derived from blood leucocytes of 347 nurses and midwives working rotating nights and 363 working during the days. The subjects were classified into unmethylated vs methylated <i>BRCA</i>1 and <i>BRCA</i>2 when the methylation index was 0% or >0%, respectively. The adjusted odds ratios with 95% confidence intervals were calculated for night work status, smoking, obesity, physical activity and alcohol drinking. Current night shift work or night work history was not associated with methylation status of the promoter sites within <i>BRCA1</i> and <i>BRCA2</i> genes. We observed weak associations between smoking and the methylation status of <i>BRCA</i>1 with OR = 1.50 (95%CI: 0.98–2.29) for current smoking, OR = 1.83, 95CI: 1.08–3.13 for smoking longer than 31 years, and 0.1>p>0.05 for trends for the number of cigarettes per day, smoking duration and packyears. In conclusion, no links between night shift work and methylation of the promoter region within the <i>BRCA</i>1, and <i>BRCA2</i> genes were observed in this exploratory analysis. The findings of our study weakly support the hypothesis that smoking may contribute to epigenetic events.</p></div

Pedagogical and psychological factors that influence player performance in youth football

Title: Psychological and pedagogical factors that influence player performance in youth football Objectives: The objective of the theoretical part is to analyze the psychological development of the player and the pedagogical aspects influencing the performance from the point of view of the educational activities of the coaches and parents. The selected theoretical starting points are then linked to the player's game play and its sporting development. The content of the research section is to examine the emotional reactions of the players of the preparatory and pupil categories in the clubs AC Sparta Praha and FK Dukla Praha. We analyzed the results of the emotional experience of the players and then we analyzed the differences of factors in the developmental stages of the sporting development and the results of the differences of emotional reactions of the players of both clubs. Methods: In this work we used a questioning method, namely a standardized DEMOR emotional reaction questionnaire examining emotional reactions of pupils. We have adapted it to the sport training environment and piloted. The research was conducted in seven teams of the AC Sparta Prague Football Club and seven teams of FK Dukla Prague in the U9-U15 category. Results: The results showed high values of positive emotional..
