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.

Atherosclerosis, one of the leading causes of death in developed countries is characterized by lumen reduction of blood vessels due to local thickening of internal blood vessels caused by plaque/atheroma. It begins in childhood, goes for a long time without manifesting symptoms, increasing with age it begins to seriously threaten health. The most important risk factors for the development of atherosclerotic disease are: hyperlipidemia, hypertension, smoking, diabetes, high fibrinogen, excessive weight, increased level of homocysteine, physical inactivity, heredity and immune response in some diseases. The primary intention of prevention is to preclude the occurrence of risk factors for atherosclerosis, and the secondary is to prevent the development or aggravation of the illness along with the reduction or control of existing risks. There is an increasing number of studies that show that children are overweight, which in adolescence is certainly a risk factor for the onset of many chronic diseases, namely: cardiovascular, type 2 diabetes, orthopedic, and psychological diseases. The obesity epidemic is one of the most serious health problems of today affecting individuals of all ages. Atherosclerosis demands action with the aim of early detection and treatment as well as the reduction of development of risk factors for coronary artery diseases. Finding the most effective preventive measures for obesity in each country requires precise epidemiological data on the number of obese children and youth, as well as on their eating and activity habits.

Objectives This study aimed to determine the status of training of adult congenital heart disease (ACHD) cardiologists in Europe. Methods A questionnaire was sent to ACHD cardiologists from 34 European countries. Results Representatives from 31 of 34 countries (91%) responded. ACHD cardiology was recognised by the respective ministry of Health in two countries (7%) as a subspecialty. Two countries (7%) have formally recognised ACHD training programmes, 15 (48%) have informal (neither accredited nor certified) training and 14 (45%) have very limited or no programme. Twenty-five countries (81%) described training ACHD doctors ‘on the job’. The median number of ACHD centres per country was 4 (range 0–28), median number of ACHD surgical centres was 3 (0–26) and the median number of ACHD training centres was 2 (range 0–28). An established exit examination in ACHD was conducted in only one country (3%) and formal certification provided by two countries (7%). ACHD cardiologist number versus gross domestic product Pearson correlation coefficient=0.789 (p<0.001). Conclusion Formal or accredited training in ACHD is rare among European countries. Many countries have very limited or no training and resort to ‘train people on the job’. Few countries provide either an exit examination or certification. Efforts to harmonise training and establish standards in exit examination and certification may improve training and consequently promote the alignment of high-quality patient care.

Aim To investigate the frequency of consumption of sweet and salty snacks among children aged 2-18 years in relation to their mothers' education level. Methods A descriptive epidemiological study was conducted in five dental practices at the School of Medicine of the University of Mostar from May to October 2022. The data were collected from medical records. Results: Out of a total of 477 children, 172 (36.1%) had mothers with a high school education, while 305 (63.9%) had mothers with a university degree. In the group of preschool children (aged 2-6 years), there were 42 mothers with high school education and 105 with university degree. In the group of school children (age 7-18 years) there were 130 mothers with high school education and 200 with university degree. The difference in the consumption of sweetened beverages among children of mothers with high school and university was not statistically significant. Similar results were found for the consumption of salty snacks, lollipops, caramels and candies. The frequency of the consumption of biscuits, chocolate and cakes (several times a day) was statistically significantly higher among the children of mothers with high school education (p=0.04), especially among school children. Eating habits of children, regardless of the level of education of their mothers, differed significantly only in the consumption of lollipops, caramels, and candies (p=0.03), which were consumed once a day by 79 (63.7%) schoolchildren and 45 (36.3%) of pre-schoolers. Conclusion A higher level of education among mothers does not necessarily equate to proper nutritional knowledge.

Objective. The aim of this study was to present data on the prevalence of seropositive children tested in the laboratory of the Eurofarm polyclinic in Sarajevo, from September 2020 to May 2021. Material and Methods. Peripheral blood samples were collected and anti-SARS-CoV-2 antibodies were detected using an electrochemiluminescence immunoassay. Results. In the total of 762 tested children, 187 were positive (24.5%), based on cut-off value. Of all the positive cases 42.8% were female while 57.2% were male. There were 10.1% of positive children in the first age group (0-5 years), 44.4% in the second group (6-13 years), and 45.5% in the third group (14-18 years). There was no statistically significant difference in seroprevalence between age groups and gender. The lowest seroprevalence (3.6%) was observed in October 2020 after the first pandemic wave, and the highest seroprevalence (60.3%) was observed in April 2021, corresponding to the third pandemic wave. Conclusion. The results of our study showed that the seroprevalence in children was low, especially during the first year of the pandemic. In the second year of the pandemic, there was an evident statistically significant increase in the number of seropositive children. Similar data have been shown in studies for adults.

Background: Cardiovascular diseases (CVD) are the cause of 17 million deaths a year worldwide, of which 25% are sudden cardiac deaths (SCD). In Europe cardiovascular diseases (CVD) remains a leading cause of death in Europe accounting for 3.9 million deaths each year. Even with well-known risk factors and the current standards of health care, improvement of health and quality of life of CVD patients are still remains one of the biggest public health challenges we must overcome. Objective: The aim of this study was to analize of current strategic documents and relevant facts of WHO and other appropriate institutions regarding CVDs prevention and control for potentialy use in Bosnia and Herzegovina (B&H). Methods: Authors made a narrative review to provide a brief overview of the recent and relevant documents of good practice in prevention, diagnostic and therapeutic approaches of cardiovascular diseases that should be consider as milestones for the health authorities in the Federation of B&H. Results and Discussion: Bosnia and Herzegovina is among the countries with a high risk of CVD together with Albania, Croatia, Czech Republic, Estonia, Hungary, Kazakhstan, Poland, Slovakia, and Turkey. The main public health challenge in Bosnia and Herzegovina is reducing noncommunicable diseases (NCDs): heart disease, stroke, cancer, diabetes and chronic respiratory disease. NCDs are estimated to account for 80% of the country’s annual deaths, and addressing them is the foremost public health priority in the country. Cardiovascular diseases still represent a worldwide public health problem, with some new dimensions caused by challenges caused through pandemic of COVID-19. The well-known cardiovascular risk factors require new and more efficient public health approaches to the prevention and control. Conclusion: Due to the recently developed cardiovascular guidelines that were made by the European Society of Cardiology and World Heart Federation, key priority for health authorities should be is to update the existing CVD guidelines in the Federation of BiH in accordance with the international good practice to support healthcare professionals in their efforts to reduce the burden of cardiovascular disease in both individual patients, as well as at a population level..

Introduction: Although evidence has demonstrated that SARS-COV-2 primarily affects the upper respiratory tract, other systems are also involved such as gastrointestinal and cardiovascular system. At present, there is insufficient data on cardiovascular and immunologic involvement in COVID-19 paediatric patients. Patients and Methods: This study evaluated 70 children previously healthy or with no pre-existing heart disease from Sarajevo with positive post-COVID history. Detailed cardiovascular examination was performed, with parameters of body weight, height, oxygen saturation, pulse, blood pressure, electrocardiogram (ECG), 24hrs Holter ECG, echocardiography. Laboratory tests included values of polymerase chain reaction (PCR) and SARS-COV-2 immunoglobulin G /IgG/ and immunoglobulin M /IgM/, CBC /complete blood count/, creatinine phosphokinase myofibrilae /CPKMB/, creatinine phosphokinase/CPK/, lactate dehydrogenase /LDH/, liver enzymes, D dimer, C reactive protein/CRP/ and urine. Results: Majority of children (64.3%) were asymptomatic. ECG was normal in relation to patients’ age, except in eight patients (intermittent palpitations on exertion): short PR interval, so in 24hrs ECG Holter there was no significant arrhythmias except incomplete right branch block / IRBB/ in 12%, monofocal ventricular ectopicextrasystole /VES/ in 15%. Echocardiogram was normal in all patients with normal ejection fraction of the left ventricle, no pericardial effusion, vegetations or thrombus was detected. Mean diameter of coronary arteries right /RCA/ and left /LCA/ ranged from 1.98 mm to LCA 2.09 mm except in one symptomatic patient a diameter of left coronary artery /LCA/ was enlarged up to 3.8 mm. The concentration levels of COVID-19 IgG showed a statistical significance when compared between younger and older age groups in examined children (p < 0.05;p = 0.043). Conclusion: Cardiovascular evaluation should always be an option in post-COVID patients. Immunological assessment is necessary in post-COVID patients in order to gain a further understanding of patient’s status. © 2022 Hrvatski Lijecnicki Zbor. All rights reserved.

Abstract Background: Limited data exist on training of European paediatric and adult congenital cardiologists. Methods: A structured and approved questionnaire was circulated to national delegates of Association for European Paediatric and Congenital Cardiology in 33 European countries. Results: Delegates from 30 countries (91%) responded. Paediatric cardiology was not recognised as a distinct speciality by the respective ministry of Health in seven countries (23%). Twenty countries (67%) have formally accredited paediatric cardiology training programmes, seven (23%) have substantial informal (not accredited or certified) training, and three (10%) have very limited or no programme. Twenty-two countries have a curriculum. Twelve countries have a national training director. There was one paediatric cardiology centre per 2.66 million population (range 0.87–9.64 million), one cardiac surgical centre per 4.73 million population (range 1.63–10.72 million), and one training centre per 4.29 million population (range 1.63–10.72 million population). The median number of paediatric cardiology fellows per training programme was 4 (range 1–17), and duration of training was 3 years (range 2–5 years). An exit examination in paediatric cardiology was conducted in 16 countries (53%) and certification provided by 20 countries (67%). Paediatric cardiologist number is affected by gross domestic product (R2 = 0.41). Conclusion: Training varies markedly across European countries. Although formal fellowship programmes exist in many countries, several countries have informal training or no training. Only a minority of countries provide both exit examination and certification. Harmonisation of training and standardisation of exit examination and certification could reduce variation in training thereby promoting high-quality care by European congenital cardiologists.
