<p><strong>Introduction. </strong>Test anxiety implies an intense pathological fear in situations of preparing and taking exams which is a significant problem for 15&ndash;70% of medical students. The frequent use of psychoactive substances is recognized as a problem for young people. The aim was to determine the frequency and degree of test anxiety and the association with misuse of psychoactive substances in medical students of the Faculty of Medicine in Foča.<br /><strong>Methods.</strong> The research was conducted according to the principle of a cross-sectional study at the Faculty of Medicine in Foča. Students were offered a custom-made questionnaire containing general and specific questions for test anxiety and use and dependence of psychoactive compounds and social networks. Test anxiety was evaluated by Westside anxiety scale.&nbsp;<br /><strong>Results.</strong> The sample included 145 respondents, 69.7% females and 30.3% males. The results indicate that the degree of test anxiety does not differ in male and female students, but test anxiety is less pronounced in younger students and students with medium academic success. The level of test anxiety was correlated with the rate of psychoactive compound use. Psychoactive substances were used by 50.3% of students, primary for anti-anxiety, than for psychostimulation and for hypnotic effects. The most commonly used classes of psychoactive substances were plant anxiolytics, followed by benzodiazepines, marijuana, alcohol and narcotics/cocaine (18.6%, 12.4%, 12.4%, 8.3%, and 4.8%, respectively).<br /><strong>Conclusion.</strong> A significant number of students reach for anxiolytics and other drugs that can create addiction. Elevated levels of test anxiety are positively correlated with increased consumption of psychoactive compounds. However, the frequency of use of psychoactive compounds surpasses the frequency of altogether moderate, high and extreme test anxiety.</p>

<p><strong>Introduction. </strong>Antibiotic resistance is a major threat to public health globally. The aim was to examine the impact of the COVID-19 pandemic on the distribution and antimicrobial resistance of pathogenic microorganisms isolated from samples&nbsp;<br />obtained during standard hospital care in one hospital center. &nbsp;<br /><strong>Methods.</strong> Data were obtained retrospectively from a database of the hospital microbiology laboratory. Study sample consisted of 3012 samples tested before the pandemic in 2019 and 3130 samples from the pandemic period in 2021.&nbsp;<br /><strong>Results.</strong> There was no statistically significant difference in the occurrence of agents that were resistant to all antibiotics between the observed years, but there was the difference in the occurrence of those agents between departments, with the highest frequency in the intensive care unit and the COVID-19 department (p&lt;0.001). Isolation of Acinetobacter bacteria increased 2.7 times, and Clostridioides difficile 6.4 times during 2021 compared to 2019. Statistically significant differences were registered in resistance to: imipenem, piperacillin-tazobactam, ceftayidime, cefepime, glycopeptides, aminoglycosides, levofloxacin and ciprofloxacin in 2021 compared to 2019.&nbsp;<br /><strong>Conclusion. </strong>Our results suggest possible influence of COVID-19 on antimicrobial resistance and input a need for a new larger study addressing this issue.</p>

<p>Diabetic retinopathy (DR) is a chronic microvascular complication of diabetes. Due to the dramatic increase in the number of diabetes cases, the prevalence of DR has also risen, making it the leading cause of blindness among the working-age population worldwide, despite the availability of screenings and modern therapeutic options. Risk factors for the development and progression of DR (duration of diabetes, hypertension, hyperglycemia, dyslipidemia, and genetic factors) have been investigated in numerous epidemiological studies and clinical researches, but the research results were not consistent. In recent years, there has been considerable interest in the study of dyslipidemia in diabetes as one of the factors that could influence the onset and progression of DR, as well as apolipoproteins as potentially better biomarkers for DR. The results of our research also point in that direction. Identifying the risk factors for DR is crucial for enabling adequate prevention and raising awareness among individuals with diabetes about the importance of taking appropriate measures to prevent this microvascular complication.</p>

The constant worsening of antimicrobial resistance (AMR) imposes the need for an urgent response. Use of antibiotics (AB), both due to irrational prescribing by doctors and irrational use by patients, is recognized as one of the leading causes of this problem. This study aimed to identify knowledge, attitudes, and practices about AB use and AMR within the general population, stratified by age, gender, and urban/rural areas during the COVID-19 pandemic. This questionnaire-based cross-sectional study was conducted in April 2022 among patients who visited three health centers in the eastern region of Bosnia and Herzegovina. A high frequency of AB use was observed during the COVID-19 pandemic (64.2% of respondents were treated with AB). Age and place of residence have not been shown to be factors associated with AB use practices that pose a risk for AMR. However, female gender (β = 0.063; p = 0.041), better knowledge (β = 0.226; p < 0.001), and positive attitudes (β = 0.170; p < 0.001) about use of AB and towards to AMR proved to be factors associated with better practice by respondents. Women, younger respondents, and respondents from urban areas showed better knowledge, attitudes, and behavior about the use of AB and AMR during the COVID-19 pandemic.

: Satureja montana L. (SM) has a long traditional use as a spice and a medicine for various gastrointestinal disorders, including painful spasms and diarrhea. Contrary to conventional drugs, administration of SM and its extracts are considered safe. Previous studies have shown that the essential oils (EOs) of SM from different areas are rich in monoterpenes, sesquiterpenes, diterpens, and phenolic compounds, including flavonoids, tannins, and acids with great composition variability. Determination of composition of EO from Herzegovinian SM done by gas chromatography-flame ionization detection and gas chromatography mass spectrometry (GC-FID and GC/MS, respectively) revealed carvacrol as a primary substance followed by γ -terpinene, p -cymene, and β -caryophyllene. Ex vivo spasmolitic activity caused by EO was evident in different types of isolated rat ileum function with the most potent effect on spontaneous activity followed by electrical field stimulation and KCl-and CaCl 2 -induced activity. SMEO produced in vivo antidiarreal activity on castor oil-induced diarrhea in young rats and showed the potential to cause a decrese water content in the feces of adult Wistar rats.This study indicates that effects of SM on the intestinum could be mediated through combination of Kv channel activation and Ca channel blockade, but additional mechanisms might be involved. The results of this study corroborate the traditional use of SM as antispasmodic, antidiarrheal, and antisecretory agents.

Introduction: Antimicrobial resistance and the rapid spread of multiresistant bacteria represent one of the main public health problem in limited resources countries. This issue is significantly worsening since the COVID-19 pandemic due to the unreasonably increased antibiotics prescription to patients with confirmed SARS-CoV-2 infection. The aim of this study was to examine whether COVID-19 pandemic (2020, 2021) was associated with increased antibiotic consumption in inpatient and outpatient settings in the middle size urban region (Republic of Srpska/Bosnia and Herzegovina) in comparison to period before the pandemic (2019). Additionally, we aimed to determine antimicrobial resistance and the presence of multiresistant bacteria in the regional hospital (“Saint Apostol Luka” Hospital Doboj) in 2021. Methodology: The consumption of antibiotics in inpatient was calculated as Defined Daily Dose per one hundred of patient-days. The consumption of antibiotics in outpatient was calculated as Defined Daily Dose per thousand inhabitants per day. Resistance of bacteria to antibiotics is expressed as a rates and density for each observed antibiotic. The rate of resistance was calculated as a percentage in relation to the total number of isolates of individual bacteria. The density of resistance of isolated bacteria against a specific antibiotic was expressed as the number of resistant pathogens/1000 patient days. Results: Antibiotic consumption in hospital setting registered during 2019, 2020 and 2021 was as follows: carbapenems (meropenem: 0.28; 1.91; 2.33 DDD/100 patient-days, respectively), glycopeptides (vancomycin: 0.14; 1.09, 1.54 DDD/100 patient-days, respectively), cephalosporins (ceftriaxone: 6.69; 14.7; 14.0 DDD/100 patient-days, respectively) and polymyxins (colistin: 0.04; 0.25; 0.35 DDD/100 bed-days, respectively). Consumption of azithromycin increased drastically in 2020, and dropped significantly in 2021 (0.48; 5.61; 0.93 DDD/100 patient-days). In outpatient setting, an increase in the consumption of oral forms of azithromycin, levofloxacin and cefixime, as well as parenteral forms of amoxicillin-clavulanic acid, ciprofloxacin and ceftriaxone, was recorded. In 2021, antimicrobial resistance to reserve antibiotics in hospital setting was as follows: Acinetobacter baumanii to meropenem 66.0%, Klebsiella spp to cefotaxime 67.14%, Pseudomonas to meropenem 25.7%. Conclusion: Recent COVID-19 pandemic was associated with increased antibiotic consumption in inpatient and outpatient settings, with characteristic change of pattern of azithromycin consumption. Also, high levels of antimicrobial resistance to reserve antibiotics were registered in hospital setting with low prevalence of identified pathogen-directed antimicrobial prescription. Strategies toward combat antimicrobial resistance in the Doboj region are urgently needed.

Complications in colorectal surgery carry a high risk of morbidity and mortality, prolong hospitalization time and increase treatment costs, and the largest number of postoperative complications is related to surgical site infection (SSI). Antibiotic prophylaxis started in the fifties of the last century and changed with each new antibiotic. The following were used in order: aminoglycosides (1943), macrolides (1952), polymyxins (1958), and cephalosporins (1965). With the discovery of metronidazole in 1970, the prophylactic spectrum was extended to include anaerobic bacteria, which are an indispensable part of the flora in this anatomical region. Due to the nature of the gastrointestinal tract, it was believed that oral antibiotic prophylaxis and mechanical bowel preparation (MBP) could achieve intestinal sterilization and thus ensure a safe surgical intervention. However, studies have shown that MBP did not have an overall beneficial effect on postoperative complications and caused significant patient discomfort, so it was almost abandoned. Today, it is known that about 16% of surgical infections are caused by multiresistant bacteria, and only oral antibiotic prophylaxis is not sufficient to prevent these infections. Namely, in the race between bacterial resistance and the development of new antibiotics, antibiotics are increasingly lagging, and the treatment of complications remains a nightmare for surgeons. For this reason, the prevention of SSI in colorectal surgery is a challenge for 21st-century medicine. In modern surgery, both open and laparoscopic, the first and second generations of intravenous cephalosporins are most often used for prophylactic purposes, as antibiotics of a sufficiently broad spectrum, with favorable pharmacokinetics and rare side effects. New research indicates that in colorectal surgery, the combination of standard intravenous prophylaxis with the addition of an oral antimicrobial the day before surgery is superior when it comes to SSI prevention. However, there are still no clear recommendations on the regimen and type of antibiotics and they should be given in institutional guides and protocols, taking into account the bacterial spectrum in the local environment, as well as resistance, and the availability of appropriate drugs. Therapeutic use of antibiotics is reserved for acute conditions in colorectal surgery and its complications. For therapeutic purposes, more potent antibiotics are used against the expected pathogens, usually a combination of several antibiotics, such as third or fourth-generation cephalosporins, metronidazole, fluoroquinolones, or piperacillin/tazobactam and others. When it comes to the therapeutic use of antibiotics in colorectal surgery, research indicates that the most important thing is to recognize the infection in time and immediately start treatment, correct the therapy according to the causative agent, and also to stop the administration of antibiotics in time, to avoid unwanted complications and already advanced bacterial resistance.

The pandemic of COVID-19 has brought many changes in health care systems at all levels of health care. The increase in the number of cases of COVID-19 has led to overuse and misuse of antibiotics.The aim of this study was to compare the consumption of antibiotics for systemic use in outpatients in the Republic of Srpska (RS), before and during the first year of the COVID-19 pandemic, as well as the association between antibiotic consumption and the rate of incidence and mortality of COVID-19. The total consumption of the antibiotics for systemic use (J01) in outpatients in the Republic of Srpska during 2019 was 19.40 DDD/TID, with an increase to 30.80 DDD/TID in 2020.Significantly higher use of penicillin (10.58 ± 11.01 DDD/TID in 2019 vs. 17.10 ± 13.63 DDD/TID in 2020), cephalosporins (2.68 ± 1.90 DDD/TID in 2019 vs. 5.93 ± 2.77 DDD/TID in 2020) and macrolides (2.14 ± 2.22 DDD/TID in 2019 vs. 3.40 ± 3.44 DDD/TID in 2020) was observed during the pandemic period. It is necessary to improve the prescribing practice of antibiotics at the primary health care level, public awareness about rational use of antibiotics, as well as the current antibiotic stewardship programs and control their implementation.

Digitalization is introducing a virtual representation of the physical world. Such virtual or digital assets, interconnected via global communication network, open unbounded management opportunities that are realized in form of software. Nowadays, digitalization is not a matter of technology change, but is rather perceived as a prerequisite of modern and sustainable operation. Thus, proactive digitalization continuously increases the complexity of globally interconnected software systems and new emerging technologies may bring significant improvements in their management. Management and sustainable goals depend on sound and effective software system engineering solutions. In this paper, we discuss modeling complex software systems within a water supply case study, in which digitalization is introduced to accomplish sustainable goals. Our focus is on water leak report and repair process, for which we open interesting further research and development challenges, based on our previous experiences in modeling complex software systems and in modeling software failure report and repair process.
