Background: The COVID-19 pandemic has significantly affected people’s lifestyles, particularly influencing existing chronic conditions such as hypertension. It is estimated that 1.28 billion adults aged 30–79 worldwide have hypertension. In addition to its impact on blood pressure levels, the pandemic also affected the quality of life and mental health of hypertensive patients. Mental health among individuals with chronic diseases who have recovered from COVID-19 is an important and complex issue. Research indicates that these patients are at a considerably higher risk of developing anxiety, depression, and PTSD, as well as experiencing deterioration of their underlying conditions. Objective: The aim of this study was to analyze the impact of independent factors on the mental health score using the SF-36 questionnaire among hypertensive patients who recovered from COVID-19. Methods: A cross-sectional study was conducted in selected primary healthcare centers across four cantons in the Federation of Bosnia and Herzegovina (FBiH). The study included a total of 240 patients, randomly selected from those diagnosed with hypertension who had recovered from COVID-19 (experimental group, n = 120). The control group consisted of 120 participants who had recovered from COVID-19 but did not have hypertension. The European SF-36 questionnaire was used for longitudinal self-assessment of health status in patients with various chronic conditions. Results: The analysis of independent factors affecting mental health during the COVID-19 pandemic showed poorer mental health outcomes among older, single participants with higher educational attainment. In relation to COVID-19 treatment, patients who had been hospitalized or treated in Intensive Care Units and who experienced cardiac complications exhibited worse mental health scores. Conclusion: The findings of this study indicate a statistically significant higher likelihood of poorer mental health among hypertensive patients who had contracted COVID-19.

Background: Posterior pericardiotomy has been proposed to prevent postoperative pericardial effusion and tamponade in coronary artery bypass grafting, but its effect on pleural fluid accumulation during off-pump CABG (OPCAB) is not well defined. Objective: To compare intraoperative metrics and early postoperative outcomes—particularly rates of pleural and pericardial effusions—between OPCAB with and without posterior pericardiotomy. Methods: In this retrospective cohort, 68 patients underwent OPCAB from January to March 2025 and were stratified into pericardiotomy (n = 38) and control (n = 30) groups. Baseline demographics, comorbidities, left ventricular ejection fraction, operative time, and graft count were recorded. Postoperative outcomes included incidence of pericardial and pleural effusions (confirmed by echocardiography or chest radiography), new-onset atrial fibrillation (within seven days), chest-tube drainage volume, and in-hospital mortality. Results: Groups were similar in age (mean 66.5 ± 7.1 years), sex, and major comorbidities, though peripheral artery disease and multi-vessel coronary disease were more prevalent in the pericardiotomy group (p = 0.002 and p = 0.017). Operative time and ICU stay did not differ significantly. Mediastinal drainage was higher after pericardiotomy (861 ± 551 vs. 764 ± 347 mL; p = 0.03). Pericardial effusion rates were low and comparable (10.5% vs. 13.3%; p = 0.72), and no tamponade occurred. Pleural effusions were significantly more frequent with pericardiotomy (42.1% vs. 6.6%; p = 0.001). Atrial fibrillation incidence and in-hospital mortality were similar between groups. Conclusions: Posterior pericardiotomy in OPCAB effectively prevents clinically significant pericardial effusion and tamponade, though it redirects fluid into the pleural space, increasing pleural effusion rates. These effusions are manageable with routine drainage and do not prolong recovery. Prospective studies should further define patient selection and long-term implications.

The post-World War II reconstruction of Europe includes the extensive construction of large number of multi-story residential buildings. At the beginning, mostly masonry buildings were built, typically with semi-prefabricated floor structures. However, since 1960s, reinforced concrete (RC) structural systems became predominant. The Balkan Peninsula and the former Yugoslavia lie within a seismically active zone of Southeastern Europe, where seismic analysis is a part of everyday structural engineering design. Buildings erected 50 to 70 years ago generally do not comply with contemporary design codes, particularly seismic ones. Their analysis presents a particular challenge for structural engineers due to many unknowns, starting with material properties, construction methods, and often some geometric data. his issue has been discussed using examples of typical multi-story buildings constructed in the city of Sarajevo, Bosnia and Herzegovina, from the mid-1950s to the early 1980s. These include masonry buildings with walls made of solid brick and high-rise buildings with R.C: walls and slabs. Analyses showed that a regular structural system plays a key role in order to achieve good seismic performance.

The aim of this study was to examine the effect of combining a low-glycemic index carbohydrate diet with structured strength training on the morphological characteristics of recreational participants. The sample included 16 subjects (8 men and 8 women), aged 19 to 50. The program lasted an average of 87.56 days. Participants followed a low-glycemic dietary regimen six days per week, with a free-choice diet on the seventh day. Strength training was conducted five times per week in the afternoon and consisted of a warm-up, main workout, and cooldown. Morphological measurements were performed using bioelectrical impedance analysis (Tanita BC-587) and a standard tailor's measuring tape. The results showed statistically significant improvements (p < .05) in all monitored parameters, including reductions in body weight, body fat percentage, circumferences, and metabolic age, as well as an increase in total body water. Sex-based analysis revealed that, aside from differences in height and metabolic rate (favoring males), there were no statistically significant differences in progress, suggesting similar program effectiveness across genders. The combination of a low-glycemic index diet and structured strength training can produce significant improvements in body composition among recreational exercisers, regardless of sex.

Background/Aim: Cranberry (Vaccinium macrocarpon, Aiton) extracts are widely utilised in dietary supplements due to their rich content of polyphenolic compounds, particularly anthocyanins and proanthocyanidins (PACs), which are associated with antioxidative and antimicrobial activities. However, commercial products often lack detailed phytochemical characterisation, raising concerns about efficacy and stability, especially in the presence of additives such as vitamin C. This study aimed to characterise the polyphenolic content of a commercial dry cranberry extract by quantifying its anthocyanins and PACs using both the 4-dimethylaminocinnamaldehyde (DMAC) and modified Bate-Smith assays to explore potential stabilising agents for improved extract stability. Methods: Anthocyanins and vitamin C were quantified using HPLC-DAD. PACs were quantified using two complementary colorimetric methods: DMAC (with catechin chloride as standard) and a modified Bate-Smith method (with procyanidin B2 standard). Antioxidative activity was assessed using DPPH and ABTS assays. Literature-based evaluation of succinate and glutamate was conducted to assess their potential as polyphenol stabilisers. Results: Five major anthocyanins were identified, with total content of 9.95 mg/g. PAC content was determined as 53.57 % via DMAC and 36.31 % via Bate-Smith, underscoring the impact of method selection. Antioxidant assays confirmed strong activity (IC50 = 110 µg/mL ABTS, 92.85 µg/mL DPPH). Vitamin C content was low (1.2 mg/g), consistent with extract maturity. Literature suggests that succinate, due to its diacidic nature, may provide enhanced stabilisation compared to other additives. Conclusion: Analysed cranberry extract was rich in bioactive polyphenols and exhibited significant antioxidant potential. The comparison of analytical methods highlights the need for standard harmonisation. Stabilisation strategies such as succinate addition should be further evaluated to enhance the shelf-life and efficacy of cranberry-based nutraceuticals.

Background: Community-acquired bacterial meningitis (CABM) remains a life-threatening infection with high morbidity and mortality, despite advances in antibiotic therapy and vaccination. Understanding local epidemiology is crucial for improving outcomes. Objective: To evaluate clinical and epidemiological characteristics and outcome of patients with bacterial meningitis in all age groups. Methods: This retrospective study analyzed 78 cases of CABM treated at the University Clinical Center Tuzla from 2014 to 2024. Patients were divided by age and outcome. Clinical features, laboratory results, microbiological findings, and prognostic factors were examined. Results: Adults comprised 59% of cases, and children 41%, with a median age of 29 years. The most common symptoms were fever (91%), positive meningeal signs (76.9%), vomiting (69.2%), and headache (66.7%). Streptococcus pneumoniae (24.4%) and Neisseria meningitidis (14.1%) were the leading pathogens. Mortality was 14.1%, significantly higher in adults (19.6%) than in children (6.3%). Poor outcomes were associated with older age, coma, ICU admission, and complications such as cerebral abscess or shock. Laboratory indicators of worse prognosis included thrombocytopenia, elevated urea and creatinine, hypokalemia, and low CSF cell count. Conclusion: CABM remains a serious clinical problem in Tuzla Canton. Early recognition, appropriate empiric antibiotic treatment, ICU management, and preventive measures such as vaccination are essential for improving survival, particularly in high-risk populations.

Milk and dairy products are nutritionally rich foods, providing energy and high-quality proteins along with a number of essential micronutrients. In this way, the dairy sector supports the existence of people in food chains around the world. Human activities affect the Earth's climate because they cause the release of huge amounts of greenhouse gases, which are retained in the Earth's atmosphere along with the gases that are naturally present in it. Food and drink are considered to be responsible for 20 to 30% of the impact on the environment, in which meat and dairy products are the most important. Research and methodologies are mostly focused on the emission of greenhouse gases (GHG), but numerous other impacts on the environment must also be taken into account, such as impacts on land and water through various types of pollution. In addition, the consumption of scarce water reserves and energy resources is also taken into account. Therefore, a sustainable approach to food and beverage production has no alternative. The dairy sector faces challenges to which it responds with numerous organized and synchronized actions and projects in order to successfully restructure and fit into the overall human activities to reduce pollution. Sustainability itself has 3 dimensions, ecological, economic and social. The aim of this paper is to present the current situation of sustainability in the dairy sector in the world and numerous activities undertaken by various actors in the dairy sector, from farm entities and dairy companies to various associations and umbrella organizations such as the International Dairy Federation, the European Dairy Association as well as non-specific dairy-strictly unrelated bodies. All activities are carried out in coordination and under the auspices of the United Nations and its organizations, primarily the Food and Agriculture Organization.
