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.

Introduction: Various studies conducted in the past few years have shown a causal relationship between human papillomavirus(HPV) and benign and malignant lesions on the laryngeal mucosa. There are no other studies on the association between HPV and laryngeal lesions in Bosnia and Herzegovina. The aim of the study was to investigate the influence of HPV infection on the development of benign and malignant lesions in the larynx. Methods: Samples for the recommended HPV analysis were taken using cotton swabs from Digene’s Specimen Collection Kit (Sample Collection Kit) from the surface of the affected area of the laryngeal mucosa with a gentle rotational movement through the directoscope. Detection of the presence of HPV in the endolaryngeal swab was performed using Digene’s HPV test-Hybrid Capture II, and results were obtained on a DML 2000 luminometer.Results: In this study, a total of 40 patients were enrolled. Among them, 17 cases (42.5%) presented with benign lesions of the larynx, whereas 23 cases (57.5%) had malignant lesions. Within the group of 17 cases with benign lesions, 5 tested positive for HPV: 2 for high-risk HPV (HR HPV), 2 for low-risk HPV (LR HPV), and 1 for both high-risk and LR HPV. Among the 23 cases with malignant lesions, 11 (47.83%) were HPV positive: 5 for HR HPV, 4 for LR HPV, and 2 for both high-risk and LR HPV. Conclusion: Our findings underscore the noteworthy influence of HPV infection on both benign and malignant changes in the laryngeal mucosa. However, future studies necessitate larger sample sizes and the identification of specific virus types.

INTRODUCTION Acute bacterial meningitis (ABM) is a serious infectious disease and medical emergency. Given the fact of its high mortality and morbidity, detecting prognostic factors is potentially useful in improving treatment strategies. This paper aims to determine prognostic factors of short-term outcomes of patients with ABM in a developing country - Bosnia and Herzegovina, measured by the Modified Rankin Scale (MRS) at discharge. METHODOLOGY In this retrospective cohort study, 56 patients treated at the Clinic of Infectious Diseases, Clinical Center University of Sarajevo, for 11 years (2012-2022) were included. Statistical analysis was performed using IBM SPSS Statistics version 29.0.1.0. RESULTS The subjects' average age was 31.6 ± 27.7 years, with the youngest patient being 4 months and the oldest 75 years old. Among those, 31 were male and 25 were female. Unfavorable outcomes had 16 (28.6%) patients, including fatal outcomes in four patients and severe disabilities in 12 patients (MRS: 2-6), while 40 (71.4%) patients had favorable outcomes (MRS: 0-1). In the multivariate analysis, predictors of unfavorable outcomes included age older than 60 years, duration of symptoms longer than 24 hours, presence of neurological defects at admission, impaired consciousness, respiratory distress, and no corticosteroid use during treatment. CONCLUSIONS There is certainly a window of opportunity for patients with ABM: The shorter the time between disease onset and treatment initiation, the better the disease outcome.

Manual microscopic differentiation of leukocytes is the primary tool for the diagnosis and monitoring of various diseases. Recently, digital optical microscopy has become a more common method, being an alternative to the conventional one, and therefore, there is a need to investigate its compatibility in more detail. The objective is to compare the results of digital and manual microscopy in the analysis of different leukocyte types and to assess the linearity, systemic and proportional differences between the methods. 109 samples were analyzed by manual and digital microscopy (Sysmex DI-60), and the comparison of the obtained results was performed by Passing-Bablok and Bland-Altman analysis. The linearity of the methods is satisfactory in all cells, except basophils and blasts. A statistically significant systemic difference was detected in segmented neutrophils, immature granulocytes, and lymphocytes, and correlations between the methods range from very strong to moderate, depending on the type of cells. Significant deviations were observed in leukocytosis and leukopenia. The results of the conducted analysis indicate a good correlation between digital and manual microscopy, but the identified systemic and proportional differences indicate the significance of the reclassification offered by the analyzer. In cases of severe leukopenia and leukocytosis, it is recommended to use manual microscopy as an additional check.

Biodentine, a tricalcium silicate cement, has emerged as a retrograde root-end filling material to promote periapical lesion (PL) healing after apicoectomy. However, its underlying mechanisms remain unclear. This study tested the hypothesis that Biodentine stimulates the osteogenic differentiation of mesenchymal stromal cells (MSCs) derived from PLs. The Biodentine extract (B-Ex) was prepared by incubating polymerized Biodentine in RPMI medium (0.2 g/mL) for three days at 37 °C. B-Ex, containing both released microparticles and soluble components, was incubated with PL-MSCs cultured in either a basal MSC medium or suboptimal osteogenic medium. Osteogenic differentiation was assessed by Alizarin Red staining and the expression of 20 osteoblastogenesis-related genes. Non-cytotoxic concentrations of B-Ex stimulated the proliferation of PL-MSCs and induced their osteogenic differentiation in a dose-dependent manner, with a significantly enhanced effect in suboptimal osteogenic medium. B-Ex upregulated most early and late osteoblastic genes. However, the differentiation process was prolonged, as indicated by the delayed expression of wingless-type MMTV integration site family member 2 (WNT2), bone gamma-carboxyglutamate protein (BGLAP), bone morphogenic protein-2 (BMP-2), growth hormone receptor (GHR), and FOS-like 2, AP-1 transcription factor subunit (FOSL2), compared with their expression under optimal osteogenic conditions. The stimulatory effect of B-Ex was primarily calcium dependent, as it was reduced by 85% when B-Ex was treated with the calcium-chelating agent EGTA. In conclusion, Biodentine promotes the osteogenic differentiation of PL-MSCs in a calcium-dependent manner, supporting its stimulatory role in periapical healing.

Origanum compactum, Melaleuca alternifolia, and Cinnamomum camphora essential oils are recognized for their therapeutic potential, including their selective cytotoxicity against cancer cell lines. Our research focused on examining the cytotoxic effects of these essential oils on three human carcinoma cell lines: lung carcinoma (H460), cervical adenocarcinoma (HeLa), and colorectal carcinoma (HCT116). The MTT-based cell viability assay was used to assess the cytotoxicity of essential oils. The results demonstrated that all three essential oils exhibited dose-dependent cytotoxic potential, with varying levels of growth inhibition across the cell lines. Notably, the highest sensitivity was observed in H460 cells, and the lowest sensitivity was found in HCT116 cells. Origanum compactum demonstrated the strongest cytotoxicity across all cell lines (GI50 73 - 154 nL/mL), making it the most promising candidate for further investigation, particularly for lung and cervical cancer treatment.

Machine-learning-based surrogate models offer significant computational efficiency and faster simulations compared to traditional numerical methods, especially for problems requiring repeated evaluations of partial differential equations. This work introduces the Geometry-Informed Neural Operator Transformer (GINOT), which integrates the transformer architecture with the neural operator framework to enable forward predictions for arbitrary geometries. GINOT encodes the surface points cloud of a geometry using a sampling and grouping mechanism combined with an attention mechanism, ensuring invariance to point order and padding while maintaining robustness to variations in point density. The geometry information is seamlessly integrated with query points in the solution decoder through the attention mechanism. The performance of GINOT is validated on multiple challenging datasets, showcasing its high accuracy and strong generalization capabilities for complex and arbitrary 2D and 3D geometries.

We report the existence of two exotic compact objects in the leading relativistic model of modified Newtonian dynamics, namely aether-scalar-tensor theory. This model is consistent with precision cosmology and gravitational wave constraints on tensor speed. Black hole mimickers could subtly change observations: gravitational waves from their mergers might show unusual echoes or altered ringdown patterns, and images of their horizon-scale shadows might be slightly different from those of a true black hole. Shapiro-free lenses are massless objects that deflect light without any gravitational time delay, producing distinctive lensing events. These predictions connect to ongoing and future gravitational-wave searches, horizon-scale imaging, and time-domain lensing surveys.

Background and Objectives More than half of the endovascularly treated ischemic stroke patients with incomplete reperfusion (expanded Thrombolysis in Cerebral Infarction [eTICI] <3) show delayed reperfusion (DR) on 24-hour perfusion imaging, which is associated with favorable clinical outcome. The effect of intravenous thrombolysis (IVT) on the rates of DR remains unclear. This study aimed to assess the treatment effect of IVT on the occurrence of DR. Methods Pooled data from 3 randomized controlled trials (EXTEND-IA and EXTEND-IA TNK parts 1 and 2) and 2 comprehensive stroke centers (University Hospitals Graz and Bern) were analyzed. Only patients with a final reperfusion score of eTICI 2a-2c and available perfusion imaging at follow-up of 24 ± 12 hours were included. The primary outcome was the presence of DR on 24-hour follow-up CT/MRI perfusion imaging, defined as the absence of any focal perfusion deficit on perfusion imaging, despite incomplete reperfusion on the final angiography series during thrombectomy. For the secondary analysis, we explored the association between the primary outcome (DR) and the time elapsed between start of IVT and the end of an intervention. To address confounding in observational data, we performed a target trial emulation. Results Of 832 included patients with eTICI 2a-2c (median age 74 years, 49% female), 511 (61%) had DR. There was an independent treatment effect of IVT on DR (standardized risk ratio [sRR] 1.1, 95% CI 1.0–1.3; standardized risk difference [sRD] 8.2%, 95% CI 0.2%–16.1%), after adjusting for age, sex, atrial fibrillation, number of device passes, collateral score, and eTICI. Among those patients who have received IVT (n = 524/832, 63%), when adjusting for the aforementioned covariates, there was a causal effect of shorter time between administration of thrombolytics and end of the intervention on DR (sRR 0.93%, 95% CI 0.87–0.98; sRD −5.2%; 95% CI −9.1% to −1.3%, per hour increase). Discussion Exposure to thrombolytics showed independent treatment effect on the occurrence of DR among patients with incomplete reperfusion after thrombectomy who undergo perfusion imaging at the 24-hour follow-up. The effect of thrombolytics on DR was observed if there was a high chance of therapeutic concentrations of thrombolytics at the time point when the proximal vessel was recanalized, but distal occlusions persisted and/or occurred. Classification of Evidence This study is rated Class III because it is a nonrandomized study and there are substantial differences in baseline characteristics of the treatment groups.

Introduction: Sensory integration is the way in which the nervous system processes information from the senses. Irregularities or disturbances in brain function that make it difficult to integrate sensory input from stimuli lead to sensory disintegration. The proprioceptive sensory system provides information about joint and body movements, extent, strength, duration and direction of movement, position of the body or body parts in space, and muscle tone. The aim of this study is to investigate the prevalence of sensory integration disorders of the proprioceptive sensory system in children with intellectual disabilities and children without developmental disabilities and to determine whether the existing difference is statistically significant. Methods: The study was conducted on a sample of 60 respondents. The first subsample of respondents (n = 30) consisted of children with intellectual disabilities. The second subsample of respondents (n = 30) consisted of children without developmental disabilities of the same chronological age. The measuring instrument “Questionnaire for examining proprioceptive sensory sensitivity” was used. Data were collected by observing the respondents and interviewing the rehabilitator and the child’s parents. The frequencies and percentages of the respondents’ answers for all variables were calculated. To determine the statistical significance of differences, the Mann-Whitney U test and Wilcoxon W test were used at a statistical significance level of p < 0.05. Results: The results show that 81.4% of children with intellectual disabilities have difficulties with sensory integration of the sensations of the proprioceptive sensory system, manifested as hypersensitivity (37.6%), hyposensitivity (19.5%), and mixed sensory response (24.3%). Sensory integration difficulties are also experienced by 75.7% of children without developmental disabilities, manifested by hypersensitivity (17.62%), hyposensitivity (27.6%), and mixed sensory reactions (30.5%). There is a statistically significant difference in the variables: high-risk games, fine motor tasks, and activities requiring physical strength. For the other variables, the difference in sensory integration is not statistically significant. Conclusion: 81.4% of children with intellectual disabilities and 75.7% of children without developmental disabilities have difficulties in sensory integration of the proprioceptive sensory system. Children with intellectual disabilities show better integration of proprioceptive sensory input in activities requiring physical strength and in activities with eyes closed or covered. In all other activities, they show poorer sensory integration of proprioceptive sensations than children without developmental disabilities.

Background/Objectives: The human kallikrein-related peptidase 6 (KLK6), a serine protease with trypsin-like properties, belongs to the 15-member kallikrein (KLK) gene family and is predominantly recognized for its role in oncogenesis, neurodegenerative disorders, and skin conditions. Aquaporins (AQPs) are integral membrane proteins that facilitate water transport across cell membranes. AQP1 is constitutively active in the kidneys and plays a crucial role in reabsorbing filtered water, while AQP2 is regulated by vasopressin and is essential for maintaining body fluid homeostasis. The primary objective of the present study is to investigate the spatio-temporal expression patterns of KLK6, AQP1, and AQP2 throughout normal human nephrogenesis and congenital kidney and urinary tract (CAKUT) abnormalities: duplex kidneys, horseshoe kidneys, and dysplastic kidneys. Methods: An immunofluorescence analysis of KLK6, AQP1, and AQP2 was performed on 37 paraffin-embedded fetal kidney samples. The area percentage of KLK6 in the kidney cortex was calculated in normal developing samples during developmental phases 2, 3, and 4 and compared with CAKUT samples. Results: KLK6 exhibits distinct spatiotemporal expression patterns during human kidney development, with consistent localization in proximal tubules. Its subcellular positioning shifts from the basolateral cytoplasm in early phases to the apical cytoplasm in later stages, which may be strategically positioned to act on its substrate in either the peritubular space or the tubular fluid. KLK6 expression followed a quadratic trajectory, peaking at Ph4. This marked increase in the final developmental phase aligns with its strong expression in mature kidneys, suggesting a potential role in proximal tubule differentiation and functional maturation through facilitating extracellular matrix remodeling and activating proteinase-activated receptors, modulating the signaling pathways that are essential for tubular development. In duplex kidneys, structural abnormalities such as ureteral obstruction and hydronephrosis may upregulate KLK6 as part of a reparative response, while its downregulation could impair epithelial remodeling and cytoskeletal integrity, exacerbating dysplastic phenotypes. Conclusions: These findings highlight the potential of KLK6 involvement in normal kidney development and the pathology of CAKUT.
