Introduction: Dehydration develops when the body fluid losses exceed fluid intake. It may occur during exercise, heat stress, restricted fluid intake, or any combination of these. Marginal dehydration (loss of > 2% body weight) can compromise aerobic exercise performance, particularly in hot weather conditions, and may disturb fluid and electrolyte balance. The aim of the study was to determine the quantity, type and dynamic of fluid intake during athletic performance in endurance sports (football and basketball) in two age categories: juniors (under the age of 18) and seniors (over the age of 18).Methods: Research included 100 athletes playing in Premier League in Bosnia-Herzegovina. We formed groups by sport type (football and basketball) and age (<18 and ≥18 years). Questionnaire with questions about the fluid intake habits was used for data collection.    Results: There were 53 football players and 47 basketball players. All the participants were male. Average age of the participants was 19.3 ± 4.58. Habit of weighing before and after training was present in less than 44% of players among all the groups. Seniors were more frequently measuring their weight compared to junior players (p=0.01). Basketball players and players younger than 18 years were most frequently taking more than 2L of water per day. Most of the players, regardless of sport type or age group were not taking at least ½ L of isotonic fluid before the training. Signs of dehydration were more frequently observed in players under 18 years old, with most frequent sign being dry throat and sudden fatigue.Conclusion: Water and electrolytes intake before, during and after training of the athletes were inadequate regardless of type of sports and the age of athletes.

Introduction: Depression is the most common mental problem in elderly and is often under-recognized or is inadequately treated, thus significantly affecting the quality of life of elderly people. The reasons for the occurrence of depression in the elderly are multiple. The most common are neurobiological and psychosocial risk factors as well as physical illness. The aim of this study is to determine the presence of the most common risk factors related to the degree of depression, determined by the geriatric depression scale.Methods: This is cross-sectional, descriptive and analytical study undertaken on the sample of 150 psychologically and physically capable residents of the "The Gerontology Center" in Sarajevo older than 65 years. The following instruments were used for research: the Geriatric Depression Scale (GDS) and the modified questionnaire on risk factors important in the depression development.Results: Women are more depressed than men (p<0.01). Depression severity increases with age (p=0.008). The marital status of respondents was significant factor affecting the GDS scores (p=0.009). GDS score and education are weakly correlated (p=0.07) and more educated are less depressed. Also, independently mobile elderly are less depressed (p<0.0005). GDS scores and presence of depression in younger age are dependent (p=0.004). Depression and subjective sleep disturbances are dependent (p=0.002).Conclusion: The most common risk factors for depression in elderly are gender, age, marital status, history of depression in younger age and mobility.

Introduction: Problem of addiction on psychoactive substances is one of the most diffi cult problems in a modern society, which brings serious consequences, both for the individual, his environment and the whole society.Methods: The study included 95 children and adolescents of medical school. Among the respondents, there were 44 subjects of third year of high school and 51 respondent-grader.Results: Students involved in this research as an answer to why young people start using drugs often reported curiosity in over 50% of cases, as well as pressure of friends. For students who use narkotine respondents generally thought they are  reasonable and sufficiently weak and limited personality. Thelargest number of high school students who were involved in the study did not know the individuals who use drugs.Conclusion: Drug addiction is a serious problem all over the country, and the number of addicts is becoming larger. Particularly worrisome is the fact that the consumption of the drug phenomenon is a characteristic of young population, especially high school students

Introduction: Selection of optimal nutrition for physical activity of sportsmen depends on several factors, and includes the type and duration of exercises, total energy consumption, time needed for recovery, andnutritional preferences. Proper nutrition of sportsmen relies on adequate combination and participation of all the macronutrients. The aim of this research was to analyse and determine the nutritional awareness andhabits of sportsmen depending on their age and type of sports they indulge.Methods: This is a cross-sectional, descriptive, and analytical study undertaken from May to July 2011 on the sample of 100 examinees/sportsmen of the Football Club “Željeznicar“ and Basketball Club “Bosna“.Results: General awareness of sportsmen on basic principles of proper nutrition is unsatisfactory. Statisticalsignificance per type of sport and age of sportsmen is proved through representation of macronutrients in their nutrition. For 49.1% footballers and 52% sportsmen over 19 years of age the most important combinationof macronutrients resembles the model of carbohydrates-proteins-fats, while 48.9% of basketballers and sportsmen under 18 prefer proteins-carbohydrates-fats. The study had shown a statistically significantdifference (p=0.01) between the footballers and basketballers with regard to the type of meal they consume before the trainings.Conclusion: Insufficient knowledge on the subject reflects in bad nutritional habits, especially those related to the number and arrangement of daily meals in comparison to respective sports activities.

Introduction: Depressive disorder, as a major problem of public health, takes high fourth place in its prevalence in general population, and is considered to be the second most frequent health problem of femalepopulation. Depression is the most frequent mental problem of persons in their third age of life. The aim of this study is to evaluate prevalence of depression and establish the ratio between the current number ofdiagnosed and of unrecognised depression among the residents of Gerontology Centre in Sarajevo.Methods: This is a cross-sectional, descriptive, and analytical study undertaken throughout May and June 2011 on the sample of 150 residents of “The Gerontology Centre“ in Sarajevo that were above 65 years of age. The following instruments were used for the research: the Geriatric Depression Scale (GDS), modified questionnaire consisting of two parts (general data and data related to health state), and the medical records of the residents. For statistic analysis of data was used the SPSS program for Windows.Results: According to GDS, prevalence of depression was 65.3%, out of which mild depression occurred in 46.7% cases and severe depression in 18.7%. The prevalence of verified (diagnosed) depression was 11.3per cents.Conclusions: According to the GD scale, unrecognised depressions seem to be almost six times more frequent (65.3:11%) than is the case with depressions diagnosed in medical records of the protegees of theGerontology Centre in Sarajevo. Timely recognition of depression and its treating in institutions for protection of health of persons in third age of life can substantially improve the quality of life of these patients.

Introduction: Water can support the growth of different microorganisms which may result in contamination. Therefore, the microbiological examination is required for testing the hygienic probity of water. In the study of microbial composition of untreated, natural spring and mineral water differences in the presence and number of bacteria during the two periods, winter and summer, are detectable.Methods: In our study, we analyzed and compared the following parameters, specified in the Rulebook: total bacteria and total aerobic bacteria (ml/22 and 37°C), total Coliform bacteria and Coliforms of fecalorigin (MPN/100ml), fecal streptococci as Streptococcus faecalis  (MPN/100ml), Proteus spp (MPN/100ml), and Pseudomonas aeruginosa (MPN/100 ml) Sulphoreducing Clostridia (cfu / ml). The paper is a retrospective study in which we processed data related to the period of 2005-2009 year. While working, we used the descriptive-analytical comparative statistical treatment.Results: The obtained results show statistically significant differences in the microbial composition of untreated water in the two observed periods,Conclusions: Findings were consequence of different weather conditions in these periods, which imply a number of other variable factors.

Introduction: The role of salt in the diet is very important, however what effect will lead to its entry into the organism depends on the amount of salt ingested. Elevated salt intake is a risk factor for hypertension, heart disease, adversely affects the kidneys, helps the development of osteoporosis. The aim was to examine sodium intake in the student population through an objective assessment of nutrition students and the students' subjective experience of salty foods and salty foods influence on the organism.Methods: The research is cross-sectional study, which is carried out in April 2010 among students at the University of Sarajevo.Results: More than half of students from the FHS considers that the greatest amount of salt into the body, adding salt to food during the meal, 34% considered that it was during the preparation of food by 10% of processed products in the food industry and 4% said that it was the intake of salt, which naturally found in foods. Not in a group of students there who suffer from hypertension, while in their families the disease is present.Conclusions: Subjects eat a quantity of salt that are well above the recommended. This problem must be approached in a more organized educational, health educational and research terms.

Introduction: Gastrointestinal infectious diseases are a group of frequent diseases in developing countries as a result of industrialization in food production and often consuming of the food in public places. In Bosnia and Herzegovina and in Canton Sarajevo these diseases are frequent. The aim of this work is to investigate epidemiological characteristics of the most often gastrointestinal infectious diseases in Canton Sarajevo (Enterocolitis acuta, Toxiinfectio alimentaris, Salmonellosis, Amoebiasis) compared with Viral Hepatitis A and to estimate the need for the implementation of vaccination against this disease.Methods: We used individual reports as well as monthly and annual bulletins about the movement of infectious diseases which are obligatory for reporting from the Epidemiology department of the Institute for public health in Canton Sarajevo. This work is a retrospective study, for the period 2005-2009. Descriptive- analytical method was used. In statistical processing we used mean, structure index and trend index.Results: The research showed that gastrointestinal infectious diseases are registered in a huge number in all the observed years. The most often was Enterocolitis acuta, and the rarest was Viral Hepatitis A. The diseases were mostly sporadic. Distinct seasonality and coherence with warm months in the year is expressed in Enterocolitis acuta and Intoxicatio alimentaris, while the other diseases are registered during the whole year.Conclusions: Incidence of gastrointestinal infectious diseases in Canton Sarajevo is high and we need to work intensively to improve sanitary conditions as the most eficient preventive measures. There is no justification for implementing of the vaccine against Viral hepatitis A.

It is estimated that 1 to 2% of the population in developed countries will experience a chronic wound during their lifetime. Nurses are leaders in applying innovations that can create positive results in preventing and treating chronic wounds in patients admitted to acute care hospitals. The aim of the research is to examine the knowledge of nurses-technicians about the knowledge of measures for the prevention and treatment of chronic wounds. In the research of knowledge on the treatment of chronic wounds, 349 respondents participated, employed at the primary and tertiary levels of health care. For the purposes of the research, the authors created a questionnaire based on a review of professional and scientific literature, as well as evidence in practice. The research was conducted through the Chamber of Nurses-Technicians of Sarajevo Canton and the Chamber of Tuzla Canton. Respondents from Sarajevo Canton worked significantly longer in practice, and 36.2% of respondents worked from 21 to 30 years, and 10.9% of respondents worked longer than 30 years, while among respondents from Tuzla Canton 34.8% of them, worked from 21 to 30 years and 9.9% worked for more than 30 years. 43.9% of respondents from Tuzla Canton and 39.6% of respondents from Sarajevo Canton had a certificate for the care of chronic wounds ( X 2 = 9.077; p = 0.028). The assessment of knowledge is in a direct positive relationship with the level of health care (rho = 0.187; p = 0.001).
