Background/Aim: Until March 2023, it has been reported over 676 million cases of COVID-19 globally with almost 7 million deaths caused by this disease. Aim of this study was to determine COVID-19-related deaths and to study how COVID-19 pandemic impacted mortality of residents in the Canton of Sarajevo in 2020-2022 time period. Also, aim was to analyse to what extent the number of registered non-COVID-19-related deaths have changed in the Canton of Sarajevo compared to what would have been expected in the absence of the virus to better measure the impact of COVID-19. Methods: This study used mortality data obtained from Federal Institute for Statistics for period 2017-2022. Data was analysed and presented as raw numbers, age-, sex-, cause of death - crude death rates (CDR), excess mortality and P-score. Results: CDR in the Canton of Sarajevo in 2020 was 1246.3 per 100.000 persons, 1488.6 in 2021 and 1153.4 in 2022, while in period from 2017-2019 CDR ranged from 1051.3 to 1057.9. Total CDR in 2020 increased by 18.3 % compared to 2017-2019 average CDR, this relative difference being even greater in 2021 (41.3 %) and lower in 2022 (9.5 %). In 2020-2022 time period, 9 of the 10 leading causes of death remained the same as in 2019. COVID-19 was the 3rd leading cause of death in 2020 and 2022, while in 2021 spiked as the leading cause of death. In 2020 there was increase of 7 % in deaths from non-COVID-19 related deaths compared to mean number of deaths for period 2017-2019. As for 2021, this number goes higher (9.5 %) and in 2022 was much lower (1.0 %). Conclusion: In the Canton of Sarajevo, COVID-19 pandemic made a big impact on mortality in 2020-2022 years period. Data have changed in total mortality, leading causes of death and excess mortality. Deep-rooted organisational weaknesses that were exposed during pandemic that can bring harm to population from preventable chronic diseases needs to be addressed which have impact on morbidity and at the end, on mortality.

Introduction: Due to the declaration of a state of emergency in the country due to the pandemic COVID-19, the education system was changed to online teaching. The implementation of distance education has led to an increased sedentary lifestyle, decreased physical activity, and increased use of information technologies. The purpose of this study was to analyze the sedentary habits of female students and their physical health during a period of restricted physical activity with reference to online instruction.Methods: The research was conducted among the first to third grade students of Secondary School Konjic, 45 days after the implementation of online instruction. Students of general secondary school (N = 83), business school (N = 68), and medical school (N = 55) completed the questionnaire after their parents gave their consent.Results: The total number of students surveyed was 206, with students from all three schools studied participating in online classes for up to 4 hours. Medical school students spend more than 3 hours completing schoolwork, while students at the other two schools spend up to 2 hours. Statistically significant differences in non-use of information technology during free time exist among medical students (p = 0.00). Female medical students reported daily symptoms such as headaches, reactions to the visual organ (dry eye, redness, and tearing), and pain in the fist area (twitching, cramps, and tingling). Statistically significant differences in the occurrence of pain in the upper back and chest girdle occurred in students of business school (p = 0.00) and general high school (p = 0.00) compared to medical students.Conclusion: Medical students who use information technology the most reported headaches, pain in the fist area, and frequent reactions to the sense of sight (dry eye, lacrimation, and redness). Assuming inappropriate positions during prolonged use of technology may contribute to poor posture.

Health problems associated with the consumption of foods that do not meet the hygiene and epidemiological standards are not of recent date and have been occurring continuously throughout the history of human existence. The incidence of food poisoning and foodborne transmissible diseases is three times more common in-home kitchens and households. Restaurant poisoning generally involves a larger number of people, whereas a home-based one involves individuals or a small number of people, so its likelihood of identification by the competent authority or public health organizations and services are significantly smaller. The development of the household food safety questionnaire (HFSQ) for the general population went through five phases (preparation of the questionnaire, distribution of the questionnaire to panelists and then the respondents, statistical analysis and the formation of the final version of the validated questionnaire). A total of 58 particles that formed the basis of the questionnaire were divided into four segments: demographic (10), knowledge (17), opinion (14) and food safety practice (17). Overall, the validity of the questionnaire in examining practice, knowledge and attitude was determined with Cronbach's alpha = 0.842. The total number of particles adequate for the questionnaire is 29 questions. This questionnaire is a good instrument for assessing the knowledge, attitudes and practices of food handlers in their households. Keywords— food safety, households, questionnaire, development and validation.

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: 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.
