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 Non-ST segment elevation myocardial infarction (NSTEMI) poses significant challenges in clinical management due to its diverse outcomes. Understanding the prognostic role of hematological parameters and derived ratios in NSTEMI patients could aid in risk stratification and improve patient care. AIM To evaluate the predictive value of hemogram-derived ratios for major adverse cardiovascular events (MACE) in NSTEMI patients, potentially improving clinical outcomes. METHODS A prospective, observational cohort study was conducted in 2021 at the Internal Medicine Clinic of the University Hospital in Tuzla, Bosnia and Herzegovina. The study included 170 patients with NSTEMI, who were divided into a group with MACE and a control group without MACE. Furthermore, the MACE group was subdivided into lethal and non-lethal groups for prognostic analysis. Alongside hematological parameters, an additional 13 hematological-derived ratios (HDRs) were monitored, and their prognostic role was investigated. RESULTS Hematological parameters did not significantly differ between non-ST segment elevation myocardial infarction (NSTEMI) patients with MACE and a control group at T1 and T2. However, significant disparities emerged in HDRs among NSTEMI patients with lethal and non-lethal outcomes post-MACE. Notably, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were elevated in lethal outcomes. Furthermore, C-reactive protein-to-lymphocyte ratio (CRP/Ly) at T1 (> 4.737) demonstrated predictive value [odds ratio (OR): 3.690, P = 0.024]. Both NLR at T1 (> 4.076) and T2 (> 4.667) emerged as significant predictors, with NLR at T2 exhibiting the highest diagnostic performance, as indicated by an area under the curve of 0.811 (95%CI: 0.727-0.859) and OR of 4.915 (95%CI: 1.917-12.602, P = 0.001), emphasizing its important role as a prognostic marker. CONCLUSION This study highlights the significant prognostic value of hemogram-derived indexes in predicting MACE among NSTEMI patients. During follow-up, NLR, PLR, and CRP/Ly offer important insights into the inflammatory processes underlying cardiovascular events.

The aim of the current research was to investigate the association between plasma endocan levels and metabolic control parameters, as well as to evaluate its predictive value for clinical complications in patients with type 2 diabetes mellitus (DMT2). A total of 100 DMT2 patients participated in this prospective observational study. Plasma endocan levels were significantly elevated in DMT2 patients with HbA1c > 7% (1.38 ± 0.33 vs 0.68 ± 0.23 ng/mL; P < 0.0001), compared to patients with HbA1c ≤ 7%. Patients with plasma endocan concentrations >1.10 ng/mL (median value of 1.10 ng/mL) demonstrated significantly higher levels of metabolic parameters: body mass index (BMI), HbA1c (%), fasting glucose level, LDL cholesterol, total cholesterol, triglycerides, along with significantly lower HDL cholesterol levels. Furthermore, patients with plasma endocan levels >1.10 ng/mL were found to have an increased risk for the following complications: retinopathy (relative risk [RR]: 2.7500; 95% confidence interval [CI]: 1.2150-6.2244; P = 0.0152, nephropathy (RR: 2.0952; 95% CI: 1.2294-3.5710; P = 0.0065), neuropathy (RR: 1.9945; 95% CI: 1.2025-3.3081; P = 0.0075), angina pectoris (RR: 2.4881; 95% CI: 1.0865-5.6979; P = 0.0311, hypertension (RR: 1.1372; 95% CI: 1.0060-1.2856; P = 0.0398), cardiomyopathy (RR: 2.6190; 95% CI: 1.1507-5.9612; P = 0.0218), myocardial infarction (RR: 9.4286; 95% CI: 1.2742-69.7697; P = 0.0280) and stroke (RR: 4.4638; 95% CI: 1.3765-14.4758; P = 0.0127). Correlation analysis revealed that plasma endocan levels were positively correlated with HbA1c (%) (r = 0.856, P < 0.0001), fasting glucose level (r = 0.631, P < 0.0001), LDL (r = 0.347, P = 0.0004), cholesterol (r = 0.282, P = 0.0045), and triglycerides (r = 0.366, P = 0.0002). Conversely, plasma endocan levels were negatively correlated with HDL cholesterol (r = -0.429, P < 0.0001). In conclusion, higher plasma endocan levels were strongly associated with poor metabolic control in DMT2 patients and exhibited significant predictive value for both microvascular and macrovascular complications.

<p><strong>Aim</strong> To investigate the predictors of biochemical relapse (BCR) among patients with non-metastatic prostate cancer treated with radiotherapy as the first-line therapy.&nbsp;<br /><strong>Methods</strong> The study included 91 patients diagnosed with prostate cancer at the University Clinical Centre in Tuzla, Bosnia and Herzegovina. After the radiation treatment as the first line of treatment, the patients were monitored for the next 36 months. If patients were classified in medium and high-risk groups, hormone therapy was administered. The occurrence of BCR was determined based on prostate-specific antigen (PSA) values. Potential prognostic parameters, including Gleason score (GS), PSA, tumour size (TNM), and standardised risk classification (RC), were monitored.<br /><strong>Results</strong> A total of 46 (50.5%) patients were aged 66-75, with a median PSA of 14.50 ng/mL. A Gleason score &lt;6 was found in 72 (79.1%) of patients, and 31 (34.1%) had T2c tumours. The BCR occurred in 32 (35.2%) patients, with a median relapse time of 18 months. Significant predictors of BCR were Gleason score &ge;6 (OR:4.46; p=0.006) and tumour stage &gt;T2b (OR:3.59; p=0.021). The RC showed an Area Under Curve (AUC) of 0.634 (p=0.050), indicating its potential diagnostic accuracy.<br /><strong>Conclusion</strong> Gleason score &ge;6 and TNM&gt;T2b are significant predictors of biochemical relapse in prostate cancer patients treated with radiotherapy. These results emphasize the need for additional monitoring and timely treatment of clinical disease progression in patients with Gleason score &ge;6 and tumour stage &gt;T2b.</p>

<p><strong>Aim</strong> To investigate clinical and morphometric characteristics of patients with lower urinary tract symptoms (LUTS) due to lumbar spinal stenosis (LSS).<br /><strong>Methods</strong> This study evaluated LSS patients using clinical assessments of motor, sensory, bladder, and bowel functions, and functional disability scores from the Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSSQ). Morphometric analysis included MRI measurements of the anteroposterior diameter of the intervertebral disc and dural sac, and the modified Torg-Pavlov ratio (mTPR), with follow-up re-evaluations at 6 months.<br /><strong>Results</strong> Of 159 patients, 49 (30.8%) had LUTS and 110 (69.2%) were in the control group. LUTS patients had a significantly higher prevalence of neurogenic claudication (100% vs. 47.3%; p&lt;0.001), lower back pain (93.9% vs. 77.3%; p=0.011), and lower extremity pain (57.1% vs. 34.5%; p=0.008). The LUTS group also had higher ODI (54.0 vs. 50.0; p=0.019) and SSSQ score (44.0 vs. 34.0; p&lt;0.001). Morphometric analysis showed significantly lower mTPR in LUTS patients (median 0.31 vs. 0.45; p&lt;0.001), with an AUC of 0.704 (95%CI 0.627-0.774). mTPR&le;0.31 predicted surgical revision within 6 months (OR:3.4, CI: 1.2-9.8), motor deficiency (OR:2.1, 95%CI: 1.4-5.2), and persistent LUTS post-surgery (OR:4.5, 95%CI: 1.1-18.9). mTPR&le;0.34 was associated with worse follow-up outcome, including increased ODI (&beta;:3.2; 95%CI: 1.1-5.3; p=0.004) and SSSQ score (&beta;:4.8; 95%CI:2.1-7.5).<br /><strong>Conclusion</strong> LUTS patients with LSS exhibit more severe symptoms and poorer outcome, with mTPR&le;0.34 being a predictor of adverse clinical outcome and the need for surgical revision within 6 months.</p>

<p><strong>Aim</strong> To compare the impact of electrical cardioversion (ECV) and pharmacological cardioversion (PCV) on left atrial size (LA) and left ventricular ejection fraction (LVEF), as well as to identify predictors of rhythm disorder recurrence in patients with atrial fibrillation (AF) or atrial flutter (AFL).<br /><strong>Methods</strong> A prospective observational cohort study was conducted on 105 patients with persistent AF or AFL at the University Clinical Centre Tuzla. The patients were divided into two groups: 53 underwent ECV and 52 received PCV. Demographic and clinical data, including ECG and transthoracic echocardiography, were collected. Follow-up assessments were conducted at 7 days, 1 month, and subsequently every 3 months for a year.<br /><strong>Results</strong> Baseline characteristics were similar between the groups. Recurrence of rhythm disorder within one year was observed in 52.4% of cases, with ECV showing a slightly lower, though not significantly different, primary failure rate at 7 days compared to PCV (13.2% vs. 23.1%). Significant predictors of recurrence included longer duration of disorder (p&lt;0.001), hypertension (p=0.016), lack of pre-cardioversion amiodarone (p=0.027), and larger LA (p&lt;0.001). Both ECV and PCV significantly reduced LA over time, with no significant differences in LVEF between groups.<br /><strong>Conclusion</strong> Both ECV and PCV are effective in restoring sinus rhythm, with a trend towards lower recurrence in the ECV group. Predictors such as disorder duration, hypertension, lack of pre-cardioversion amiodarone, and LA should be considered when planning cardioversion to optimize patient outcomes.</p>

<p><strong>Aim</strong> Acute kidney injury (AKI) presents a high mortality complication in patients with acute myocardial infarction (AMI). Yet, its correlation with non-ST elevation myocardial infarction (NSTEMI) remains neglected in the literature. This study aims to investigate the prevalence, risk factors, clinical features, and short-term outcomes associated with AKI development in patients with acute NSTEMI.<br /><strong>Methods</strong> A one-year prospective observational cohort study involved 170 consecutive patients hospitalized in the Intensive Care Department of the Internal Medicine Clinic at the University Clinical Centre Tuzla diagnosed with acute NSTEMI. Patients were subsequently categorized into AKI and non-AKI groups based on AKI development within 48 hours. Demographic characteristics, laboratory findings, and short-term clinical outcomes were compared between the groups.<br /><strong>Results</strong> Of 170 patients, 31 (18.2%) developed AKI within 48 hours of acute NSTEMI. Significant age differences, blood urea nitrogen (BUN), creatinine, estimated glomerular filtration rate (eGFR), blood glucose level (BGL), C-reactive protein (CRP), and high sensitivity (hs) troponin were observed, making patients with lower baseline kidney function, more extensive myocardial infarction, and a heavier systemic inflammatory response following acute NSTEMI more susceptible to AKI development. In the follow-up period, mortality rates were significantly higher in the AKI group, amounting to 35.5% compared to 10.1% in the non-AKI group. Additionally, mortality increased with the severity of AKI, reaching 100% in AKI stage 2.<br /><strong>Conclusion</strong> This study highlights demographic, clinical and laboratory findings in patients with acute NSTEMI, which contribute to AKI development. Early detection and tailored interventions are crucial in mitigating AKI-associated morbidity and mortality.</p>

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.
