Background: The purpose of this meta-analysis was to examine the prevalence of hypertensive disorders of pregnancy (HDPs), particularly preeclampsia (PE), in peripartum cardiomyopathy (PPCM)-affected pregnancies, and to evaluate whether a HDP significantly alters the prognosis of PPCM, with specific reference to the recovery of left ventricular function (LVEF) and mortality. Methods: A total of 5468 potentially eligible studies were identified, and 104 were included in the meta-analysis. For pooling proportions, the inverse variance methods with logit transformation were used. Complete recovery of LVEF (>50%) and mortality were expressed by odds ratios (ORs), with 95% confidence intervals (CIs). The Peto OR (POR) was used in cases of rare events. Baseline LV function and baseline LV end-diastolic diameter (LVEDD) were summarized by the mean difference (MD) and 95% confidence interval (CI). Results: The summary estimate of the prevalence of HDPs and PE in women with PPCM was 36% and 25%, respectively. Patients with HDPs and, more specifically, PE with PPCM had a higher chance of complete recovery (OR = 1.87; 95%CI = 1.64 to 2.13; p < 0.001 and OR = 1.98; 95%CI 1.69 to 2.32; p < 0.001, respectively), a higher baseline LVEF (MD, 1.42; 95% CI 0.16 to 2.67; p = 0.03 and MD, 1.69; 95% CI 0.21 to 3.18; p = 0.03, respectively), and a smaller baseline LVEDD (MD, −1.31; 95% CI −2.50 to −0.13; p = 0.03 and MD, −2.63; 95% CI −3.75 to −1.51; p < 0.001, respectively). These results, however, did not translate into a significant difference in 12-month mortality (POR = 0.80; 95% CI = 0.57 to 1.13; p = 0.21 and POR = 1.56; 95% CI 0.90 to 2.73; p = 0.12, respectively). Conclusions: The findings of this study may contribute to evidence that can be utilized to aid in the risk stratification of patients with PPCM regarding their long-term prognoses.

Background A comprehensive understanding of the anatomy and pathology of the maxillary sinus is paramount for precise diagnosis and effective planning of dental interventions. Cone Beam Computed Tomography (CBCT) offers enhanced visualization of sinus structures, thus facilitating the identification of anatomical variations and pathological conditions which are critical for surgical and dental treatment strategies. Materials and Methods This retrospective descriptive study analyzed 200 CBCT scans, comprising 400 maxillary sinuses from patients treated at the Faculty of Dentistry University of Sarajevo. The study assessed sinus dimensions, volumes, anatomical features, their relationships with adjacent anatomical structures, and the occurrence of pathological alterations. Furthermore, the patient's gender and dental status were studied in relation to these features. The sinus measurements were performed with Sidexis 4 software (Dentsply Sirona, Germany), which is intended for precise linear measurements in three orthogonal planes. Results Significant differences were found in sinus width between patients with full dentition and those with partial or complete edentulism (p<0.01). Male participants exhibited larger mean sinus dimensions compared to females in all dimensions. The maxillary sinus floor was inferior to the nasal floor in 91.5% of cases. Various types of sinus membrane abnormalities were observed, with normal membrane thickness in 53.75% of cases. Sinus septa were most frequently located on the roof of the sinus, and their frequency varied significantly among patients with different dentition statuses. The study also identified 274 Haller cells and documented several pathological changes, with mucosal thickening exceeding 3 mm being the most common alteration. Conclusion This radiographic study of Bosnian and Herzegovian population revealed significant anatomical variations and pathological changes in maxillary sinuses, thus emphasizing the importance of careful preoperative evaluation using CBCT for surgical planning in the posterior maxillary area. The findings highlight gender-based differences in sinus volumes, the impact of dentition status on sinus anatomy, and the prevalence of various pathological conditions, thus contributing to valuable insights in the field of maxillofacial radiology.

This paper presents research related to segmentation based on supervisory control, at multiple levels, of optimization of parameters of segmentation methods, and adjustment of 3D microscopic images, with the aim of creating a more efficient segmentation approach. The challenge is how to improve the segmentation of 3D microscopic images using known segmentation methods, but without losing processing speed. In the first phase of this research, a model was developed based on an ensemble of 11 segmentation methods whose parameters were optimized using genetic algorithms (GA). Optimization of the ensemble of segmentation methods using GA produces a set of segmenters that are further evaluated using a two‐stage voting system, with the aim of finding the best segmenter configuration according to multiple criteria. In the second phase of this research, the final segmenter model is developed as a result of two‐level optimization. The best obtained segmenter does not affect the speed of image processing in the exploitation process as its operating speed is practically equal to the processing speed of the basic segmentation method. Objective selection and fine‐tuning of the segmenter was done using multiple segmentation methods. Each of these methods has been subject to an intensive process of a significant number of two‐stage optimization cycles. The metric has been specifically created for objective analysis of segmenter performance and was used as a fitness function during GA optimization and result validation. Compared to the expert manual segmentation, segmenter score is 99.73% according to the best mean segmenter principle (average segmentation score for each 3D slice image with respect to the entire sample set). Segmenter score is 99.49% according to the most stable segmenter principle (average segmentation score for each 3D slice image with respect to the entire sample set and considering the reference image classes MGTI median, MGTI voter and GGTI).

Background: Myocardial injury (MI) is characterized by an increased level of at least one cardiac troponin. Experimental MI can be induced by isoprenaline, a β-adrenergic agonist, and it can lead to heart failure (HF). Liraglutide is glucagon-like 1 peptide receptor agonist used in diabetes management, but it has anti-inflammatory and antioxidative effects, which can be beneficial in treatment of HF. The aim of this study was to investigate the effects of liraglutide on isoprenaline-induced MI and prevention of HF. Methods: Male Wistar albino rats were divided into four groups: Con—received saline the first 2 days + saline the next 7 days; Iso—isoprenaline the first 2 days + saline the next 7 days; Lir—saline the first 2 days + liraglutide the next 7 days; Iso + Lir—isoprenaline the first 2 days + liraglutide the next 7 days. On day 10, blood samples were taken for biochemical analysis and oxidative stress marker evaluation, and hearts were isolated for pathohistological analysis. Cardiac function was assessed by electrocardiography (ECG) and echocardiography (ECHO). Results: Liraglutide treatment significantly attenuated oxidative stress, repaired ECG and ECHO parameters, and mitigated myocardial morphological changes induced by isoprenaline. Conclusions: Liraglutide restores cardiac function in isoprenaline-induced HF.

Dynamic programming (DP) is a fundamental algorithmic strategy that decomposes large problems into manageable subproblems. It is a cornerstone of many important computational methods in diverse fields, especially in the field of computational genomics, where it is used for sequence comparison. However, as the scale of the data keeps increasing, these algorithms are becoming a major computational bottleneck, and there is a need for strategies that can improve their performance. Here, we present Vectron, a novel auto-vectorization suite that targets array-based DP implementations written in Python and converts them to efficient vectorized counterparts that can efficiently process multiple problem instances in parallel. Leveraging Single Instruction Multiple Data (SIMD) capabilities in modern CPUs, along with Graphics Processing Units (GPUs), Vectron delivers significant speedups, ranging from 10% to more than 20x, over the conventional C++ implementations and manually vectorized and domain-specific state-of-the-art implementations, without necessitating large algorithm or code changes. Vectron's generality enables automatic vectorization of any array-based DP algorithm and, as a result, presents an attractive solution to optimization challenges inherent to DP algorithms.

Abstract The adoption of the United Nations General Assembly Resolution A/RES/78/282, designating 11 July as the International Day of Reflection and Commemoration of the 1995 Srebrenica genocide, embodies a significant effort in combating genocide denial. However, the Resolution generated substantial preemptive and reactive backlash, sparked by a global network of actors committed to revising the history of the 1990s. This article provides a detailed account of the resolution’s contextual history within the UN, as well as an analysis of the geopolitical and ideological underpinnings of Srebrenica genocide denial as a tool of regional nationalist and revisionist agendas. As a salient example, the article explores the coordinated campaign led by Serbia and Republika Srpska to undermine the resolution, utilizing it to mobilize nationalist tropes, discredit international institutions, and reinforce denialist narratives.

Abstract Pike-perch Sander lucioperca is a native species originally present in the Black Sea basin of Bosnia and Herzegovina. In the 1990s, it was introduced to the Neretva River and its reservoir system, and since 2009 the species has been recorded in Lake Boračko and Buško Blato Reservoir. The aim of this study is to analyse the distribution of S. lucioperca in Bosnia and Herzegovina based on literature data (1975–2024) and to define areas where the species has been introduced in order to assess the risk of potential invasiveness. The results indicate that S. lucioperca belongs to the high-risk category. Since the same risk ranking has been confirmed in recent studies on aquatic ecosystems in other geographical areas, the conclusion is that pike-perch could soon pose a potential threat to native species and aquatic ecosystems in Bosnia and Herzegovina if mitigation measures are not implemented.

Introduction: Aneurysms of brain vessels are life-threatening conditions with various adverse outcomes, some stemming from microsurgical intervention, particularly when major vessel perforators are inadequately protected. The use of endoscopes enhances the approach to aneurysms by providing closer visualization (180–360 degrees) of the local anatomy, potentially reducing accidental damage. To improve visualization and efficiency, a microscope-integrated 45-degree angled microinspection endoscopic tool (QEVO®, Carl Zeiss, OberkochenTM) has been developed and employed in various neurosurgical procedures. Methods: Between 2021 and 2025, 27 brain aneurysms were treated with QEVO® assistance at the Department of Neurosurgery, Clinical Center of the University of Sarajevo. The choice of the videos corresponds to the best image quality in videos and on the microscopic determination of adjacent vessel perforators, which were not adequately seen purely by the surgical microscope in specific cases. Exclusion criteria included cases without a need for QEVO® assistance in perforator visualization, severe brain edema, intraoperative aneurysm rupture, posterior circulation, or low video quality. Results: Case 1 demonstrates an anterior choroidal artery (AchA) aneurysm; Case 2 presents an anterior communicating artery (AcommA) aneurysm; and Case 3 features contralateral middle cerebral artery (MCA) microsurgical clipping with QEVO® assistance. Conclusions: The QEVO® tool significantly improves the visualization of aneurysm–perforator relationships, increasing the likelihood of preserving perforators during standard microsurgical clipping. This innovative approach may reduce surgical complications and enhance patient outcomes, highlighting the tool’s potential as an adjunct in aneurysm microsurgery.

This is the first study of microelement variability in needles of seven natural populations of Picea omorika (Panč.) Purkyně from Serbia. Seven essential, three usefull, and six toxic microelements were analysed by ICP-Spectrometer. Their range was as follows: Mn > Fe > Zn > Al > Na > B > Cu > Ni > Cr > Cd > Co. The microelements Mo, As, Hg, Pb and Se were detected in traces. The amounts of Al, B, Co, Cr and Na were recorded in P. omorika needles for the first time. Among usefull microelements the most abundant was Al, while among toxic it was Cr. The most southern population, Mileševka canyon, had the highest amounts of Zn, Cu, Ni, Co and Cd and the lowest values of B. Discriminant and cluster analyses visualized that this population also showed the greatest separation from all other populations. Further research could usefully explore factors that affect the endangerment of P. omorika in its natural habitats or prevent its natural regeneration.
