OBJECTIVES: An unhealthy lifestyle, inappropriate eating habits, and inadequate physical activity are the most common risk factors affecting health and causing the premature onset of non-communicable diseases. The study aimed to evaluate lifestyle factors, eating habits, and daily regimens in a sample of Slovak adolescents. METHODS: The sample involves 524 students aged 15-22 years attending selected secondary schools from the model region of Bratislava, the capital of Slovakia. We assessed the prevalence of selected lifestyle factors and investigated the relationship between negative lifestyle factors and the presence of overweight and obesity. RESULTS: We found eating irregularities including avoidance of school lunch, inadequate daily consumption of vegetables, dairy products and wholegrain foods, and the high consumption of sweets and sweetened beverages. The prevalence of excess weight and obesity in the sample was 18.4%. Compared to the non-obese, overweight or obese students had significantly lower daily consumption of vegetables and used to avoid sports more frequently. Almost 37% of students did not do sports at all. Students who were not doing sports on regular basis used to skip breakfast more frequently, they ate fewer vegetables and more sweets and spent considerable time in sedentary activities. CONCLUSION: In the sample of secondary school students, we investigated several negative lifestyle factors and the relatively high prevalence of overweight and obesity. The results of the study can be used for the development of preventive measures to protect and promote the health of children and youth.

OBJECTIVES: The study aimed to investigate the use of electronic cigarettes (EC) among medical students, their knowledge and beliefs (opinion about harmfulness and addiction potential) on ECs, perceptions of the risk, as well as to assess the type of education and cessation training they received during their study at Faculty of Medicine, Comenius University in Bratislava, Slovakia. METHODS: This cross-sectional, anonymous online e-mailed survey was conducted among medical students via the Study Department by sending e-mails containing the survey link. Participants completed the online questionnaire adapted from the American Survey on Tobacco and Alternative Tobacco Products. It included questions about the personal use of EC, perceptions about the harms and their role in disease causation, education and cessation training, and practices related to conventional cigarettes (CC), EC, and alternative tobacco products (ATP). The e-mailed questionnaire filled in 577 medical students (71.9% women) from Comenius University in Bratislava, the average age was 23 ± 2 years. The sample comprised 486 (84.2%) Slovak and 91 (15.8%) foreign students. The data were analysed using the Statistical Package for Social Science (SPSS) version 25. RESULTS: There were 385 (66.7%) non-smokers, 111 (19.3%) ex-smokers and 81 (14%) current smokers in the study sample. EC currently use 13.5% of medical students, with a statistically significant intersexual difference (22.2% males vs. 10.12% females; OR = 2.53, 95% CI: 1.55-4.13), more foreign students than Slovak students (24.2% vs. 11.52%; OR = 2.44, 95% CI: 1.41-4.26), more smokers of conventional cigarettes than non-smokers (46.9% vs. 8.06%; OR = 10.07, 95% CI: 5.85-17.34). EC seems to be less harmful to 59.97% of students, mostly in the age group ≤ 24 (61.76% vs. 51.49%; OR = 1.46, 95% CI: 1.03-2.07), 41.25% of students consider EC to be less addictive, 55.6% think they do not get enough education on EC during their medical study. CONCLUSION: The results overall show the high consumption of tobacco products and the lack of knowledge and awareness among medical students, future health care providers. In health promotion and disease prevention, they should serve as a model for their patients and for the general public as well. Our study emphasizes the need for intervention in this field at medical faculties and for support of further monitoring in Slovakia and other countries and draws attention to the ongoing lack of EC regulation.

The protein kinases ataxia-telangiectasia mutated (ATM) and ATM-Rad3 related (ATR) are activated in response to DNA damage, genotoxic stress and virus infections. Here we show that during infection with wild-type adenovirus, ATR and its cofactors RPA32, ATRIP and TopBP1 accumulate at viral replication centres, but there is minimal ATR activation. We show that the Mre11/Rad50/Nbs1 (MRN) complex is recruited to viral centres only during infection with adenoviruses lacking the early region E4 and ATR signaling is activated. This suggests a novel requirement for the MRN complex in ATR activation during virus infection, which is independent of Mre11 nuclease activity and recruitment of RPA/ATR/ATRIP/TopBP1. Unlike other damage scenarios, we found that ATM and ATR signaling are not dependent on each other during infection. We identify a region of the viral E4orf3 protein responsible for immobilization of the MRN complex and show that this prevents ATR signaling during adenovirus infection. We propose that immobilization of the MRN damage sensor by E4orf3 protein prevents recognition of viral genomes and blocks detrimental aspects of checkpoint signaling during virus infection.
