Heat stress is a significant problem in the military services. This study investigated the effects of exertional heat stress on cognitive performance.
Forty unacclimated male soldiers performed exertional heat stress tests in cool (20 °C) and hot environments (40 °C). Cognitive performance was assessed using a computerized battery before and immediately after tests. Physical strain in cool conditions induced mild but significant deficits in accuracy in complex tests. The number of correct answers in the Matching to Sample Visual Search was reduced (92,18% correct answers before vs. 88,64 after; p<0,05) and also in the spatial part of the Pattern and Spatial Recognition Memory Test (85,25 vs. 8,75%; p<0,05). These decreases were more pronounced in hot conditions (92,38 vs. 84,31% in before and 84,21 vs. 73,42% in the latter test; ps<0,01 and <0,001, respectively). Exertional heat stress also impaired more simple cognitive functions. A significant decrease in accuracy (95,74 vs. 93,89%) and an increase in reaction time (300,32 vs. 315,00 ms) was observed in the Reaction Time test.
Strenuous physical activity in a hot environment induces mild cognitive deficits, especially in more complex tasks.

The aim of this study was to determine the prevalence of alcohol consumption among adolescents in Serbia and its association with sociodemographic characteristics. This paper is based on data from a national health survey of the population of Serbia in 2013 (no data for Kosovo and Metohija), conducted by the Ministry of Health of the Republic of Serbia. For the purposes of this study, data on households and individuals over 15 years of age were used; thus, the final sample for analysis included 858 patients (aged 15 to 19 years). Researchers used demographic characteristics (age, gender, type of home, region) and socio-economic characteristics (income per household member, the index of well-being, self-assessment of health, cigarette smoking, tendency towards psychological and physical violence) as the independent variables. A χ2 test was applied to test the differences in the frequencies of categorical variables. The correlations between alcohol consumption, as the dependent variable, and the independent variables (mentioned above) were tested by logistic regression. All results less than or equal to 5% probability (p ≤ 0.05) were considered statistically significant. The prevalence of alcohol consumption among adolescents in Serbia is 51.6%. Alcohol consumption is significantly associated with sex, type of home and the index of well-being (p < 0.05). The prevalence of alcohol consumption is higher in males (57.1%), in adolescents who come from urban areas (59.3%) and in adolescents who, according to the index of well-being, belong to the wealthiest financial category (23.9%).

Background: Psoriasis vulgaris (PsV) is a chronic skin condition that has a major impact on health-related quality of life (HRQOL).
Aim: To determine the individual burden of PsV on HRQOL using willingness to pay (WTP) instrument.
Materials and methods: Fifty-one consecutive PsV patients were asked to evaluate their overall health and psoriasis affected health by visual analogue scale (VAS), and interviewed on 8 domains (physical, emotional, sleep, work, social, self-care, intimacy, and concentration) of HRQOL and WTP for a hypothetical cure in each domain. Two additional questions proposing 6 alternatives for therapy were also asked. The analysis is performed with descriptive and frequency statistics, Mann-Whitney and Kruskal-Wallis tests.
Results: The domains ranked highly were: physical comfort (90%), social comfort (77%), emotional health (75%) and work (53%). The following tendencies concerning WTP for top four impacted domains were found: the median WTP were the highest in the top impacted domains; the younger patients were willing to pay more than the older ones; the highest median WTP amounts appear in the lowest income group; the highest median WTP is associated with smaller psoriasis affected health VAS scores. The largest proportion and number of patients (37.3%, n=19) stated preferences for the systemic therapy. The second preferred choice was the thalassotherapy (29.4%, n=15).
Conclusions: The utility and reliability of the instrument based on the assessment of WTP stated preferences for 8 domains of HRQOL for evaluation the individual burden of psoriasis were strongly supported.
