Introduction: The impact of nutrition on human health has become a central topic in modern research. The Mediterranean diet, rich in fruits, vegetables, fish, whole grains, and olive oil, has been associated with a lower risk of cardiovascular diseases. However, the effects of non-Mediterranean diets, particularly among students, remain insufficiently explored. This study aimed to examine differences in the dietary habits of health sciences students in two cities in Bosnia and Herzegovina (Mostar and Sarajevo) and Split, Croatia. Methods: A cross-sectional descriptive study was conducted between February and November 2024, including 473 students (Mostar: 125, Sarajevo: 230, Split: 118). Dietary habits were assessed using a validated food frequency questionnaire and the Mediterranean Diet Adherence Screener. Statistical analysis included Pearson’s chi-square test, with significance set at p < 0.05. Results: Students from Split showed significantly higher adherence to Mediterranean dietary habits, including greater consumption of vegetables (p = 0.009), fish (p = 0.035), legumes (p = 0.036), and tomato sauce (p = 0.022). Students in Sarajevo reported the highest intake of sugary drinks (p < 0.01), while those in Split consumed the least margarine and cream-based fats (p = 0.003). No significant differences were found in fruit consumption. Conclusion: Given the importance of diet in preventing chronic diseases, targeted nutrition education programs are needed to promote healthier eating habits among students. Future research should explore the underlying causes of these dietary differences and their long-term health implications.

Objectives. The purpose of this study was to determine whether fear and prejudice in relation to organ donation and the transplantation of organs may influence the decision to become an organ donor. Materials and Methods. Data were collected through four group interviews using open-ended questions and qualitative content analysis. Forty participants, 16 males and 24 females from seven countries, participated in the focus group interviews. Results. The analysis resulted in three main categories, and nine subcategories. Fears and prejudice caused by tradition and customs, approval of organ donation by family members, perception of the body as a gift from parents, the influence of religious leaders, knowledge about the religious understanding of organ donation, influence of social ambience on respondents, knowledge of the donation process in the healthcare system, including knowing about life after eventual organ donation, were some of predictors in the decision to agree to organ donation. Conclusion. More education on the factors that influence organ donation, more information in schools, health institutions and through the media, as well as more research with the aim of “dispelling” fears and prejudice about organ donation would significantly improve the current situation and result in a larger number of potential organ donors.

Background: Transplantation of cells, tissues, and organs enables many patients to regain impaired organ function, promoting healing or prolonging life and improving overall quality of life. Objective: The aim of this study was to assess the knowledge and attitudes of students in Federation of Bosnia and Herzegovina regarding organ donation and transplantation of organs. Methods: A cross-sectional study was carried out with 255 students from four different faculties in Federation of Bosnia and Herzegovina, with the majority enrolled in either the Faculty of Medicine or the Faculty of Health Sciences. The students collected data using a self-administrative questionnaire, providing sociodemographic characteristics, knowledge and attitudes about organ donation and transplantation. Statistical analysis was performed using Microsoft Excel version 3645 and R studio v2024.04.2, based on R 4.4.1. Results: Out of all students, 49 of them (19.3%) demonstrated poor knowledge, while 131 students (51.6%) exhibited average knowledge. Analyzing the data by Faculty type revealed significantly higher levels of knowledge among students in Medical and Health faculties compared to those in the Educational Science Faculty (χ2=10.196, p=0.006). Regarding attitudes, 56 students (22%) had a negative attitude, while 117 students (45.9%) had a highly positive attitude. Only 13 students (5.1%) owned a donor card. Conclusion: Students from Faculty of Medicine and Faculty of Health Sciences generally possess higher basic knowledge about organ donation, yet despite this knowledge, their attitudes toward organ donation often remain negative. It is essential to implement effective strategies aimed at raising awareness and fostering a positive attitude toward organ donation.

Background: Coronavirus disease 2019 (COVID-19) can cause a wide clinical spectrum, ranging from asymptomatic to severe disease with a high mortality rate. In view of the current pandemic and the increasing influx of patients into healthcare facilities, there is a need to identify simple and reliable tools for stratifying patients. Objective: Study aimed to analyze whether hemogram-derived ratios (HDRs) can be used to identify patients with a risk of developing a severe clinical form and admission to hospital. Methods: This cross-sectional and observational study included 500 patients with a confirmed diagnosis of COVID-19. Data on clinical features and laboratory parameters were collected from medical records and 13 HDRs were calculated and analyzed. Descriptive and inferential statistics were included in the analysis. Results: Of the 500 patients, 43.8% had a severe form of the disease. Lymphocytopenia, monocytopenia, higher C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were found in severe patients (p < 0.05). Significantly higher neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), neutrophil-to-platelet ratio (NPR), neutrophil-to-lymphocyte-to-platelet ratio (NLPR) and CRP-to-lymphocyte ratio (CRP/Ly) values were found in severe patients (p < 0.001). In addition, they have statistically significant prognostic potential (p < 0.001). The area under the curve (AUC) for CRP/Ly, dNLR, NLPR, NLR, and NPR were 0.693, 0.619, 0.619, 0.616, and 0.603, respectively. The sensitivity and specificity were 65.7% and 65.6% for CRP/Ly, 51.6% and 70.8 for dNLR, 61.6% and 57.3% for NLPR, 40.6% and 80.4% for NLR, and 48.8% and 69.1% for NPR. Conclusion: The results of the study suggest that NLR, dNLR, CRP/Ly, NPR, and NLPR can be considered as potentially useful markers for stratifying patients with a severe form of the disease. HDRs derived from routine blood tests results should be included in common laboratory practice since they are readily available, easy to calculate, and inexpensive.

Introduction. The beginning of the COVID-19 pandemic led to a lockdown resulting in an 85% reduction in the compulsory immunization of children in 82 countries in May 2020 compared to January and February 2020. The World Health Organization states that during the first four months, for the first time in 28 years, the vaccination coverage of children with the third dose of gout, tetanus, and pertussis vaccines dropped significantly. The objective of the research is to determine the effect of COVID-19 on the implementation of mandatory vaccination of children and youth in the FBiH in 2020 compared to 2019. Subjects and methods: Data for vaccination coverage for children and youth in FBiH were extracted from the official records of the Institute for Public Health of the FBiH, in 2019 and 2020. The percentage of children vaccinated through mandatory vaccination processes was analyzed, expressed as a percentage in primary vaccination and revaccination by FBiH counties in 2020 and 2019 in relation to the planned number of children. Results. The study found a decrease in vaccination with the first doses of vaccine in FBiH, with the exception of the BCG vaccine, which has an increase of 2.3% compared to 2019. In particular, there is a decrease in vaccination with the third dose of the Hepatitis B vaccine and the DTaP-IPV-Hib vaccine third dose. In 2020, in the FBiH, there was a decrease of 26.7% in vaccination with the first dose of MRP vaccine. Conclusion. The research found a significant decline in the vaccination of children and youth for almost all vaccines in all FBiH counties in 2020, which indicates an increased risk for vaccine-preventable diseases.Vaccination improvement activities in the FBiH need to be intensified in order to reduce the risk of vaccine-preventable diseases. © 2022 Hrvatski Lijecnicki Zbor.

Coronavirus disease 2019 (COVID 19) is a pandemic disease that is today a global public health problem caused by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). COVID-19 is a disease of middle and old age, but clinical expression may also be present in childhood. Asymptomatic and mild clinical forms are most often present in persons aged 0-19, but severe clinical forms such as, among others, acute respiratory distress syndrome and multisystem inflammatory syndrome may occur. In addition to presenting the epidemiology, clinical symptomatology of COVID-19, the authors consider certain specifics of COVID-19, that is, possible reasons for the lower incidence of the disease as well as unusual and rare clinical forms of the disease in children. The current activities of health professionals in the supervision of COVID-19 are mainly focused on early detection, isolation and treatment of patients, isolation of contacts, the regular and thorough practice of respiratory hygiene, hand hygiene, and physical distancing. Future efficient and safe vaccination will solve the biggest global medical challenge caused by the new coronavirus in the best possible manner.
