Background Heart failure (HF) is characterized by impaired cardiac function. Based on left ventricular ejection fraction (LVEF), it is classified into HF with reduced ejection fraction (HFrEF), mildly reduced ejection fraction (HFmrEF), and preserved ejection fraction (HFpEF). Each phenotype has distinct pathophysiological mechanisms and clinical features. Recent findings indicate that systemic inflammation is a significant factor in the progression of heart failure. Inflammatory biomarkers, including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and lymphocyte-to-monocyte ratio (LMR), may serve as valuable tools for evaluating the inflammatory response in heart failure. Materials and methods This prospective observational study, which included 171 HF patients, was conducted from February 2022 to January 2023 at the Intensive Care Unit, University Clinical Centre Tuzla. Based on LVEF, patients were categorized into HFrEF, HFmrEF, and a control group (HFpEF). The study aimed to assess the prognostic value of NLR, MLR, and LMR in predicting major adverse cardiovascular events (MACE) and mortality over a 12-month follow-up period. Results NLR and MLR were significantly higher, while LMR was lower in both HFrEF and HFmrEF compared to controls, indicating a strong inflammatory response, particularly in HFrEF. NLR demonstrated a strong ability to distinguish between HF phenotypes. HFmrEF's markedly higher high-sensitivity troponin I (hsTroponin I) level suggested higher cardiac stress. MACE rates were similar across groups; mortality was significantly higher in HFrEF. Conclusion Inflammatory biomarkers NLR, MLR, LMR, and hsTroponin I could be crucial in assessing heart failure, particularly in patients with HFrEF and HFmrEF.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS), characterized by neurodegeneration, axonal damage, demyelination, and inflammation. Recently, gut dysbiosis has been linked to MS and other autoimmune conditions. Namely, gut microbiota has a vital role in regulating immune function by influencing immune cell development, cytokine production, and intestinal barrier integrity. While balanced microbiota fosters immune tolerance, dysbiosis disrupts immune regulation, damages intestinal permeability, and heightens the risk of autoimmune diseases. The critical factor in shaping the gut microbiota and modulating immune response is diet. Research shows that high-fat diets rich in saturated fats are associated with disease progression. Conversely, diets rich in fruits, yogurt, and legumes may lower the risk of MS onset and progression. Specific dietary interventions, such as the Mediterranean diet (MD) and ketogenic diet, have shown potential to reduce inflammation, support neuroprotection, and promote CNS repair. Probiotics, by restoring microbial balance, may also help mitigate immune dysfunction noted in MS. Personalized dietary strategies targeting the gut microbiota hold promise for managing MS by modulating immune responses and slowing disease progression. Optimizing nutrient intake and adopting anti-inflammatory diets could improve disease control and quality of life. Understanding gut-immune interactions is essential for developing tailored nutritional therapies for MS patients.

Background Acute pancreatitis (AP) is a condition with various etiological factors, marked by the sudden onset of inflammation in the pancreatic tissue. Predicting the severity and potential mortality of AP involves analyzing clinical data alongside laboratory tests and imaging. Among several grading methods with strong predictive capabilities for illness severity and mortality, the Bedside Index for Severity in Acute Pancreatitis (BISAP) score is notable. This study aims to explore the potential role of laboratory markers, specifically red cell distribution width (RDW), RDW/platelet (PLT) ratio, and mean platelet volume (MPV), in predicting disease severity, with patients being stratified according to the BISAP scoring system. Materials and methods This research included 161 patients hospitalized at Cantonal Hospital Zenica in Zenica, Bosnia and Herzegovina, with a diagnosis of AP. The BISAP score was determined based on laboratory and radiological analyses. This score was used to evaluate potential correlations between laboratory findings such as RDW, RDW/PLT ratio, and MPV. Results The age range was significantly higher in patients with BISAP scores ≥3 (68 years, 64-76) compared to those with BISAP scores <3 (59.5 years, 42.75-69) (p = 0.000). RDW values were also significantly higher in patients with BISAP scores ≥3 (15.6%, 14-16.9) compared to those with BISAP scores <3 (13.5%, 13-14.1) (p = 0.000). Hospital stay duration was significantly longer for patients with BISAP scores ≥3 (9 days, 6-11) compared to those with BISAP scores <3 (5 days, 5-7) (p = 0.000). Additionally, the RDW/PLT ratio was significantly lower in patients with BISAP scores <3 (0.063 ± 0.02) compared to those with BISAP scores ≥3 (0.09 ± 0.059) (p = 0.012). Conclusion Our results indicate a significant difference in RDW/PLT ratios between patient severity groups based on BISAP scores (scores <3 vs. ≥3). This suggests that the RDW/PLT ratio may serve as a useful predictor for assessing the severity of AP. However, further research is needed to explore the full potential of the RDW/PLT ratio in evaluating AP patients.

Bosnia and Herzegovina (BiH) accumulates challenges in the areas of research and innovation (R&I), agricultural water management (AWM) and their intersection. In the decade 2012–2022, the BiH gross domestic product per capita in current US$ increased by 6.2% annually. However, improvements are slowly arriving in R&I and AWM. In this period, relevant challenges to AWM have materialized, such as climate change effects or the need to implement an interconnected vision of ecosystem services. In the R&I arena, the societal demand for knowledge goods remains low, while the reforms of higher education and R&I funding systems have become urgent. This paper set out to elaborate a realistic and feasible policy roadmap to consolidate R&I in AWM in BiH. The methodology included an assessment of policies and sector performance, the analysis of stakeholder perceptions, the development of strategic directions and the design of a strategy. Desk research and stakeholder consultations (33 interviews, six workshops, 179 persons in total) were used to take stock of the current situation and expectations for the future. Stakeholders were divided into knowledge supply and knowledge demand, with five and six subcategories, respectively. Relations were established among the key enabling factors, the needs and the capacities of the involved stakeholders. The TOWS (Threats, Opportunities, Weaknesses and Strengths) matrix permitted to identify policy strategies. A Weaknesses – Opportunities, conservative or mini-maxi strategy was selected, owing to the relevance of system weaknesses (such as low investments, poor return of R&I to society or low R&I for AWM adaptation) and opportunities (such as the Green Agenda for the Western Balkans, Smart Specialization or regional partnerships). The policy roadmap was structured along three policy goals: strengthen R&I, strengthen AWM and identify / fund local R&I priorities for AWM. Policy goals included policy instruments promoting eco-efficient use of resources and sustainable development of rural areas.

Aim To examine safety and efficiency of electrocardioversion (EC) in elective treatment of atrial fibrillation and atrial flutter in the setting of Day Hospital by determining success rate, frequency of adverse events and possible cost benefit compared to admitting a patient into hospital. Methods This prospective observational cohort study was performed in Day Hospital and in Intensive Care Department of Internal Medicine Clinic, University Clinical Centre Tuzla from January 2019 to December 2022 and included 98 patients with a persistent form of atrial fibrillation (AF) or atrial flutter. The patients who were divided in two groups, 56 hospitalized and 42 patients accessed in Day Hospital. In all patients, medical history, physical examination, electrocardiogram (ECG) and transthoracic echocardiogram (TTE) evaluation was performed in addition to laboratory findings. Electrocardioversion was performed with a monophasic General Electric defibrillator in anterolateral electrode position with up to three repetitive shocks. Results In hospital setting group overall succes rate of electrocardioversion was 85%, with average 2.1 EC attemps, there was with one fatal outcome due to stroke, one case of ventricular fibrillation (VF) due to human error, and 6 minor adverse events; with average cost of was 1408.70 KM (720.23 €) per patient. In Day Hospital setting succes rate was 88%, with average 2 EC attempts, no major adverse events, 8 minor adverse events; and average cost was of 127.23 KM (65.05 €) per patient. Conclusion Performing elective electrocardioversion in Day Hospital setting is as safe as admitting patients into hospital but substantially more cost effective.

The current study aimed to explore whether the level of decrease in platelet distribution width (PDW), platelet-large cell ratio (P-LCR), and mean platelet volume (MPV) has prognostic value for major adverse cardiovascular events (MACEs) in acute myocardial infarction without ST-segment elevation (NSTEMI) treated with clopidogrel. In this prospective observational cohort study, PDW, P-LCR, and MPV were determined on admission at the hospital and 24 h after clopidogrel treatment in 170 non-STEMI patients. MACEs were assessed over a one-year follow-up period. Using the Cox regression test, a decrease in PDW showed a significant association with the incidence of MACEs (odds ratio [OR] 0.82, 95% confidence interval [CI] 0.66–0.99, p ═ 0.049) and overall survival rate (OR 0.95, 95% CI ═ 0.91–0.99, p ═ 0.016). Patients with a decrease in PDW<9.9% had a higher incidence of MACEs (OR 0.42, 95% CI ═ 0.24–0.72, p ═ 0.002) and a lower survival rate (OR 0.32, 95% CI ═ 0.12–0.90, p ═ 0.03) than patients who had a decrease in PDW<9.9%. In the Kaplan–Meier analysis using log-rank test, patients who had a decrease in PDW<9.9% had an increased risk for MACEs (p ═ 0.002) and lethal outcomes (p ═ 0.002). However, a decrease in MPV or P-LCR did not have prognostic value. A decrease in PDW<9.9% measured 24 h after clopidogrel treatment in NSTEMI patients has good prognostic value for determining the short-term risks of MACEs, possibly providing a better risk stratification of those patients.

The highest quality silage is produced from corn (corn silage), which is also the most common livestock feed. The lack of corn silage in livestock production can be compensated only by concentrated feed, which is usually more expensive, but this is a wellapplied practice in B&H. Therefore, the main aim of this paper was to determine the economic viability of corn silage production in B&H for the period 2014-2019. Primary data for this research were collected based on a semi-structured interview with representatives of the farm "Farma Spreča" Kalesija with a total harvested area of 500 ha. Results indicate that with total harvested area increases 61.29 %, yield increases only 6.26 %, while efficiency decreased by 6.38 % implying problems related to productivity. Based on that, corn silage production in B&H shows positive financial performances, but low yield even with a strong increase in harvested areas indicates the need for further technological and technical improvement.

Aim To determine stereological structural parameters of the parenchymal part of the placenta, placental weight and volume of adolescent pregnant women and their correlation with newborns' birth weight. Methods This prospective study was conducted on a total of 60 human placentas of term pregnancy, divided into two groups according to the age of pregnant women. Experimental group consisted of 30 placentas of pregnant women aged 13-19 years. Control group consisted of 30 placentas of pregnant women aged 20-35 years. Stereological analysis was performed. Results Volumetric density of terminal villi of adolescent placentas was significantly higher than the one of control group (p <0.0001). The volumetric density of fibrinoid of adolescent placentas was significantly lower than of the control group (p <0.0001). Total volume of terminal villi of adolescent placentas was significantly higher than of the control group (p<0.0001). The total volume of fibrinoid of adolescent placentas was significantly lower than of the control group (p<0.0001). Newborns of adolescent pregnancies had in average lower birth weight of 439.01 g compared to the newborns of the control group (p <0.00001). Conclusion Adolescent pregnancy affects placental structure, weight and volume. Newborns of adolescent pregnancy have optimal body weight.
