Background: Antimicrobial resistance imposes one of the leading global health issues and is strongly associated with the overuse and misuse of antimicrobials. Objective: The present study aimed to determine the level of knowledge, attitudes, and behavior regarding the use of antibiotics among urban and rural population in the southeastern European country of Bosnia and Herzegovina. Methods: A cross-sectional questionnaire-based study was conducted by convenience sampling technique among people who visited health centers, malls, and also online. In total, 1057 questionnaires were completed, of which 920 were completed in the city of Mostar (i.e. urban area), while 137 in the municipality of Grude (i.e., rural area). Descriptive statistical analysis was performed to process the results. Results: Participants from Mostar had better knowledge about antibiotics (p = 0.031) and a higher level of education (p = 0.001). Women showed markedly better knowledge in the group of urban area responders (p = 0.004). Improper use of antibiotics was more common among respondents from Grude; they tend to use antibiotics more frequently and almost half of them are prone to self-medication (p = 0.017). Overall, those classified with adequate knowledge showed less tendency to irregular antibiotic intake. Having a medical worker in a family was significantly associated with better knowledge regarding antibiotics, while educational level was not. Conclusion: Although a significant number of respondents showed adequate knowledge about the use of antibiotics, there were noticeable irregular behavioral patterns, while significant differences between urban and rural population were detected as well. Further analysis is required to access the whole specter of the issue and to initiate policies directed toward reducing inappropriate use of antibiotics and bacterial resistance to these medications.

This study aims to determine the protein expression patterns of acetylated α-tubulin, inversin, dishevelled-1, Wnt5a/b, and β-catenin in developing (E13.5 and E15.5) and early postnatal (P4 and P14) kidneys of Dab1−/− (yotari) mice, their role in regulating the Wnt signaling pathway, and the possible relation to congenital anomalies of kidney and urinary tract (CAKUT). The analysis of target protein co-expression, observed in the renal vesicles/immature glomeruli, ampullae/collecting ducts, convoluted tubules, metanephric mesenchyme of developing kidneys, but proximal convoluted tubules, distal convoluted tubules and glomeruli of postnatal kidneys, was performed using double immunofluorescence and semi-quantitative methods. The overall expression of acetylated α-tubulin and inversin during normal kidney development increases with higher expression in yotari mice as the kidney acquires mature morphology. An increase in β-catenin and cytosolic DVL-1 levels, indicating a switch from non-canonical to canonical Wnt signaling, is found in the postnatal kidney of yotari mice. In contrast, healthy mouse kidney expresses inversin and Wnt5a/b in the postnatal period, thus activating non-canonical Wnt signaling. Target protein expression patterns in kidney development and the early postnatal period observed in this study could indicate that switching between canonical and non-canonical Wnt signaling is crucial for normal nephrogenesis, while the defective Dab1 gene product in yotari mice may promote CAKUT due to interfering with this process.

The purpose of this study was to compare the immunofluorescence patterns of autophagic markers: Light chain 3 beta (LC3B), Glucose regulating protein 78 (GRP78), Heat shock cognate 71 (HSC70) and Lysosomal-associated membrane protein 2A (LAMP2A) in the developing and postnatal kidneys of Dab1−/− (yotari) mice to those of wild-type samples. Embryos were obtained on gestation days 13.5 and 15.5 (E13.5 and E15.5), and adult animals were sacrificed at postnatal days 4, 11 and 14 (P4, P11, and P14). After fixation and dehydration, paraffin-embedded kidney tissues were sectioned and incubated with specific antibodies. Using an immunofluorescence microscope, sections were analyzed. For statistical analysis, a two-way ANOVA test and a Tukey’s multiple comparison test were performed with a probability level of p < 0.05. A significant increase in GRP78 and LAMP2A expression was observed in the renal vesicles and convoluted tubules of yotari in embryonic stages. In postnatal kidneys, all observed proteins showed higher signal intensities in proximal and distal convoluted tubules of yotari, while a higher percentage of LC3B-positive cells was also observed in glomeruli. Our findings suggest that all of the examined autophagic markers play an important role in normal kidney development, as well as the potential importance of these proteins in renal pathology, where they primarily serve a protective function and thus may be used as diagnostic and therapeutic targets.

Background:The aim of this study was to determine the presence of coagulation parameter disorders in patients hospitalized due to COVID-19 and to investigate the relationship between the abnormalities of coagulation parameters and the final outcome. Methods: We performed a retrospective cohort study of 81 patients admitted to the University Clinical Hospital Mostar, due to respiratory infection by SARS-CoV-2, in the period from March 15th to May 15th, 2021. Subjects were divided into two groups according to the final outcome. We analyzed age, sex, comorbidity frequency and parameters of coagulation function. Main findings: Of the 81 patients, 42 died and 72.7% died in the Respiratory Center (p<0.001). Two-thirds of the respondents were male. The mean age of all respondents was 72.88±14.21 years. Nonsurvivors were significantly older than survivors (p=0.002). Previous chronic disease was confirmed in 84% of the subjects and the most common comorbidity was arterial hypertension. D-dimers were elevated in 95% of the subjects. Non-survivors had a statistically significant prolongation of APTT in seconds (p=0.005) than survivors, while in other coagulation parameters, there was no statistical significance with respect to the severity of the clinical status and the final outcome. Principal conclusions: SARS-CoV-2 infection is associated with abnormalities in the parameters of coagulation function. Moreover, APTT is an important factor for prognosis assessment in patients with COVID-19.

Background: The aim of this study was to compare the level of inammatory parameters in 3 different groups of COVID-19 patients depending on severity of clinical manifestations and to dene which inammatory parameter can be used as predictor of clinical severity and outcome. A total of 51 subjects was included in this study by retrospective review of theMethods: documentation at the Clinic for Infectious Diseases of University Clinical Hospital Mostar. The following data were collected: demographic, clinical symptoms, complications, therapy, and the level of inammatory parameters (C-reactive protein at the admission, procalcitonin, leukocytes, relative neutrophils count, relative lymphocyte count). Depending on the value of paO2/O2 patients were separated into 3 groups: mild, moderate and severe group. Data entry into the tables was followed by statistical data processing using IBM SPSS Statistics v.26 and Microsoft Excel 2013. Most frequent symptoms were fever (82% of all subjects), cough (61%), trouble breathing (55%), shortness ofResults: breath (43%), chest pain (27%), muscle pain (25%), diarrhea (20%), vomiting (6%) and headache (6%). The overall mortality of this study was 35%, with a statistically much higher mortality in severe patients. Also C-reactive protein levels were higher in severe patients. Conclusions: Levels of C-reactive protein on admission were signicantly higher in patients who developed a severe clinical manifestations. Also, mortality in severe patients was statistically higher than the remaining 2 groups of patients. CRP is reported as a prognostic factor in the severity of clinical manifestations and mortality of hospitalized COVID-19 patients.
