<p><strong>Aim</strong> The position of science and scientific research in Bosnia and Herzegovina (B&H) is unfavourable. University education lacks research programs, hindering students from developing critical evaluation skills. <br /><strong>Methods</strong> This cross-sectional study examined knowledge, attitudes, experience and perceived barriers towards scientific research among biomedical students and recent graduates at the University of Sarajevo in B&H. A self-reporting questionnaire was distributed via social networks and among students from all years of the Medical, Dentistry, Pharmaceutical faculties, the Faculty of Health Sciences, and the Faculty of Science, as well as recent graduates.<br /><strong>Results</strong> The survey was completed by 243 participants. The mean knowledge score of 4.3/11 was noticed; 216 (96%) believed research was necessary for healthcare improvement. Although 147 participants (65.3%) attended courses on research methodology, only 63 (28%) engaged in scientific research at their faculties. Only 5 (8.5%) employed graduates participated in research at their jobs. Almost half, 99 (44%) participants consulted scientific papers only upon recommendation. The majority of participants, 199 (82.2%), reported they experienced barriers to conducting research in B&H. <br /><strong>Conclusion</strong> Biomedical students and graduates demonstrated limited research knowledge, but had positive attitudes and acknowledged significant barriers. Improved faculty curricula in research areas and more opportunities are needed.</p>
Environmental negotiations are complex, and conveying the interaction between science and policy in traditional teaching methods is challenging. To address this issue, innovative educational approaches like serious gaming and role-playing games have emerged. These methods allow students to actively explore the roles of different stakeholders in environmental decision-making and weigh for instance between sometimes conflicting UN Sustainable Development Goals or other dilemmas. In this work the phosphorus negotiation game (P-Game) is for the first time introduced. We present the initial quantitative and qualitative findings derived from engaging 788 students at various academic levels (Bachelor, Master, PhD, and Postdoc) across three continents and spanning 22 different countries. Quantitative results indicate that female participants and MSc students benefitted the most significantly from the P-Game, with their self-reported knowledge about phosphorus science and negotiation science/practice increasing by 71–93% (overall), 86–100% (females), and 73–106% (MSc students in general). Qualitative findings reveal that the P-Game can be smoothly conducted with students from diverse educational and cultural backgrounds. Moreover, students highly value their participation in the P-Game, which can be completed in just 2–3 h. This game not only encourages active engagement among participants but also provides valuable insights into the complex environmental issues associated with global phosphorus production. We strongly believe that the underlying methodology described here could also be used for other topics.
ABSTRACT Hypermobility spectrum disorders (HSD) and hypermobility Ehlers–Danlos syndrome (hEDS) are frequently associated with gastrointestinal symptoms, although the underlying mechanisms remain unclear. This study aimed to compare antroduodenal motility in patients with and without HSD/hEDS. We included 239 patients (50 HSD/hEDS and 189 non‐HSD/hEDS) with gastrointestinal symptoms undergoing antroduodenal manometry (ADM). The prevalence of antroduodenal dysmotility was not different between both groups, but enteric dysmotility was less common in the HSD/hEDS group (13% vs. 34%, p = 0.006). Delayed gastric emptying rates were similar, suggesting that delayed gastric emptying is more relevant for patients with HSD/hEDS and gastrointestinal symptoms.
ABSTRACT Introduction The aim of the study was to assess the seroprevalence of SARS‐CoV‐2 in the Republika Srpska, Bosnia and Herzegovina, after five waves of COVID‐19 and 1 year after introduction of vaccination to better understand the true extent of the COVID‐19 pandemic in the population of the Republika Srpska and role of vaccination in achieving herd immunity. Methods The population‐based study was conducted from December 2021 to February 2022 in a group of 4463 individuals in the Republika Srpska. Total anti–SARS‐CoV‐2 antibodies were determined in serum specimens using the Wantai total antibody ELISA assay. Quantitative analysis, using Kantaro IgG assays, was performed in subsamples (1273 specimens) to asses and compare levels of IgG among vaccinated, recovered and participants with hybrid immunity. To adjust for age and gender distribution in sample, poststratification method is applied. Results The overall cumulative seroprevalence was 94.6% (95% CI = 93.9–95.3). Significantly higher seroprevalence rates were observed among vaccinated 97.8% (95% CI = 97.3–98.4) comparing to unvaccinated participants (89.5%, 95% CI = 88.0–91.0). Seroprevalence increases with the number of received doses. Among various professions, the highest seroprevalence was found in the service industry (98.1%), education (98.0%) and healthcare (96.9%). We found that 2.2% of vaccinated and 3.6% of participants with SARS‐CoV‐2 positivity during 2021 had no detectable IgG antibodies. Both seroprevalence (98.6%) and antibody titres (1094.4 AU/mL) were significantly higher among people with hybrid immunity. Conclusion Our findings reveal a 2.3‐fold increase in seroprevalence of SARS‐CoV‐2 antibodies due to infection and vaccination, comparing to the first study performed 1 year earlier. This study provides better understanding of the SARS‐CoV‐2 transmission and highlights the important role of the vaccination in achieving the population immunity. Periodically conducted population‐based seroprevalence studies are important to understand temporal trends and assess surveillance system performance and public compliance with vaccination policies.
Introduction Alcoholic liver disease represents a growing global pandemic, particularly among younger men, and is one of the leading causes of premature death worldwide. Observing complications during the decompensation stage and monitoring disease progression dynamics using scoring systems are particularly important. Materials and methods This retrospective-prospective, descriptive, and analytical study included 123 male patients with a confirmed diagnosis of alcoholic liver cirrhosis, hospitalized at the Internal Medicine Clinic, University Clinical Centre of the Republic of Srpska in Banja Luka, Department of Gastroenterology and Hepatology. The study period spanned from January 2023 to January 2025, with the note that patient selection and monitoring began much earlier, in June 2021. After hospitalization, patients were followed monthly through a program of outpatient control examinations, with disease outcomes recorded. The study included all male patients over 18 years of age with a confirmed diagnosis of alcoholic liver cirrhosis and signed informed consent. Female patients and those with cirrhosis or other etiologies were excluded. For statistical data analysis, the Statistical Package for the Social Sciences (SPSS) version 29 (IBM Corp., Armonk, NY, USA) was used. The statistical analyses performed included median, standard deviation, analysis of variance, Student's t-test, chi-square test, and survival analysis. Results The mean age of the patients was 59.09±9.316 years. Most of them had anemia: 113 patients (91.86%) with decreased erythrocytes and 109 patients (88.62%) with decreased hemoglobin. Thrombocytopenia was observed in 104 patients (84.55%), while an increased mean corpuscular volume (MCV) was recorded in 68 patients (55.28%). Among biochemical parameters, the most common findings were increased bilirubin in 98 patients (79.67%), aspartate aminotransferase (AST) in 111 patients (90.24%), gamma-glutamyl transferase (GGT) in 109 patients (88.61%), and D-dimer in 110 patients (89.44%), while albumin levels were decreased in 107 patients (87.00%). Hyponatremia (decreased sodium) was observed in 63 patients (51.21%), and hypercalcemia (increased calcium) in 116 patients (94.30%). Jaundice was the most common external sign, present in 98 patients (79.67%), while ascites were noted in 86 patients (69.91%). Death during the first decompensation occurred in 31 patients (25.20%), of whom 17 (54.83%) died in the hospital. The leading cause of mortality is bleeding from esophageal varices. Conclusion Although a healthy liver performs over 200 distinct functions in the human body, a cirrhotic liver leads, one might say, to an even greater number of dysfunctions. This pathology is extremely complex, characterized by numerous complications and high treatment costs, which, despite all applied measures, do not ensure a favorable long-term prognosis without liver transplantation.
Since the design of wireless MIMO systems requires knowledge of the double-directional (i.e., directionally resolved at both link ends) channel characteristics, and 5G/6G use higher frequency bands, there is the need for double-directional measurements in the mmWave spectrum, along with channel sounders that can accurately perform such measurements. This paper introduces a novel channel sounding approach based on a redirecting rotating mirror arrangement (ReRoMA). The method is low-cost and flexible as it requires only a single radio frequency chain at each link end and performs mechanical beamsteering. However, in contrast to existing rotating-horn systems, it physically separates the signal generation/transmission and the beam steering components, resulting in orders-of-magnitude faster measurements. The paper outlines the fundamental concept, describes details of the implementation, and demonstrates its application and accuracy using a 60GHz prototype for measurements in static reference scenarios, as well as dynamic measurements. We illustrate the detected propagation paths using dynamic angular and delay power spectra and correlate these findings with the surrounding environmental structure. Locations of environmental objects are detected within the Fourier resolution determined by bandwidth and horn width, with no noticeable degradation due to the faster measurements.
Background: Hemoplasmas represent the type of bacteria that infect red blood cells, potentially leading to various health impacts, including changes in blood parameters. The close interaction between hemoplasma and red blood cells results in cell damage through immune-related and other unspecified mechanisms. Even with a strong immune response and antibiotic treatment, affected animals are likely to remain chronic carriers once clinical symptoms have subsided. These microorganisms were previously documented in sheep and other small ruminants worldwide. Aim: Since there is a lack of research on the link between Mycoplasma infection and blood parameters, our aim was to investigate how Mycoplasma infection affects these blood parameters. In addition, the study conducted in Bosnia and Herzegovina represents the first documented research of hemoplasma infection in goats within this region. Methods: In this research, 20 Alpine goats were sampled to investigate the presence of hemoplasma using polymerase chain reaction (PCR) analysis. Sequences of the 16S rRNA gene fragments were identified subsequently. The effect of Mycoplasma ovis (M. ovis) infection was observed on the following hematological parameters: Red blood cell count (RBC), hematocrit (HCT), hemoglobin (HGB), mean cell volume (MCV), mean cell hemoglobin, mean cell hemoglobin concentration, Reticulocyte count, and white blood cell (WBC). Effect on white blood cell differentiation, absolute white blood cell counts, platelet count, and mean platelet volume were also investigated. Results: PCR analysis confirmed the presence of Mycoplasma spp. in 7 out of the 20 blood samples. Sequencing of the 16S rRNA gene fragments revealed that all positive samples were identified as M. ovis. The research findings highlighted potential effects on blood parameters in infected goats. Goats infected with M. ovis exhibited higher mean levels of HGB and HCT compared to uninfected goats. However, there were no statistically significant differences in RBC counts between infected and uninfected groups. The study also noted significantly higher WBC counts in goats without M. ovis infection. Conclusion: 35% of animals tested positive for M. ovis. Our study’s findings showed notable differences in hematological parameters between goats infected with M. ovis and those that were not infected.
