Background and Objectives: Human papillomavirus (HPV) infection and its etiological role in the development of cervical cancer are well established. The cervical cancer mortality rate in Serbia is one of the highest among European countries, and this cancer is the second-leading cause of death in Serbian women aged from 15 to 44. Materials and Methods: This retrospective study was conducted at the Institute of Public Health of Vojvodina. A total of 10,062 cervical specimens from Serbian women were collected and HPV tested in ten years. The study patients were divided into five age groups. HPV genotype testing was performed using a commercial kit to detect 14 high-risk (HR) HPV genotypes. Additionally, cervix cytology data have been available for patients tested in 2022 and 2023. Results: An overall positive rate was found in 43.3% of patients (4356/10,062). A single HPV infection (62.1%) was the main infection pattern. The most frequent HR HPV genotypes were HPV 16, 31, 52, 56, 39, and 51, comprising 62.3% of the detected genotypes, including multiple infections. A significant difference was noted in the HPV prevalence across the different age groups, with a bimodal distribution of HPV infection. The highest prevalence was recorded in the age group ≤ 30 and those after 61 years. Women diagnosed with high-grade squamous intraepithelial lesions (HSIL) were significantly older compared to others. HR HPV is the most prevalent in patients with HSIL cytological findings (76.5%). The most common type, according to age-specific distribution and cytological findings, was HR HPV 16. Conclusions: This study provides comprehensive data on HR HPV distribution among Serbian women, which can serve as a basis for subsequent monitoring of genotypic distribution. It is particularly significant considering they are missing in the updated ICO/IARC Report for Serbia, and the cervical cancer mortality rate in Serbia is one of the highest among European countries.

Background/Aim. It had been suggested that elevated body mass index (BMI) is a beneficial and preventive factor when it comes to the outcome for patients undergoing coronary artery bypass grafting (CABG). At the same time, obesity is strongly associated with coronary artery disease development. The aim of this study was to determine the significance of the obesity paradox in patients referred for CABG and to examine if a relationship exists between obesity and early coronary surgery outcome. Methods. This study comparised 791 patients who had undergone isolated CABG over one year period (year 2010). The average age of patients was 62.33 ? 8.12 years and involved 568 (71.8%) male and 223 (28.2%) female patients, while the mean logistic EuroSCORE was 3.42%. The patients were categorized into three distinct groups based on their BMI: I - BMI < 24.9 kg/m2; II - BMI 25-30 kg/m2; III - BMI > 30 kg/m2. Regression analysis was conducted to determine whether BMI was an independent predictor of early mortality after CABG. Results. The majority of the cohort could be categorized as overweight (49%) or obese (30%). There was no association between BMI and gender (p = 0.398). The overall early mortality was 2.15% (1.85% in the group I, 2.06% in the group II and 2.51% in the group III; p = 0.869). Univariate analysis showed that obesity cannot be regarded as an independent risk factor for early mortality following CABG (odds ratio 1.021, 95% confidence interval 0.910-1.145, p = 0.724). Duration of in-hospital period following the surgery was comparable within the BMI groups (p = 0.502). Conclusion. Compared to non-obese patients, overweight and obese individuals have similar early mortality rate following CABG. This study can substantiate the presence of obesity paradox only in terms that elevated BMI patients have comparable outcome with non-obese. Further research is needed to delineate potential underlying mechanisms that set off obesity to protective factor for coronary surgery.

Purple urine bag syndrome (PUBS) is an uncommon, but usually benign, underrecognized clinical condition with the distressing presentation of purple, blue or reddish discoloration of a patient’s catheter bag and tubing in the setting of catheter-associated urinary tract infections (UTIs). PUBS is the result of the complex metabolic pathway of the dietary essential amino acid tryptophan. Its urinary metabolite, indoxyl sulfate, is converted into red and blue byproducts (indirubin and indigo) in the presence of the bacterial enzymes indoxyl sulfatase and phosphatase. The typical predisposing factors are numerous and include the following: female gender, advanced age, long-term catheterization and immobilization, constipation, institutionalization, dementia, increased dietary intake of tryptophan, chronic kidney disease, alkaline urine, and spinal cord injury (SCI). Here, we present a case of PUBS in a home-dwelling elderly female patient with a history of long-term immobility after a pathological spinal fracture, long-term catheterization, constipation, and malignant disease in remission. Urine culture was positive for Proteus mirabilis. This state can be alarming to both patients and physicians, even if the patient is asymptomatic. Healthcare professionals and caregivers need to be aware of this unusual syndrome as an indicator of bacteriuria in order to initiate proper diagnostics and treatment.

Background/Objectives: Adequate knowledge and correct attitudes about the HPV vaccine influence awareness of the importance of preventing HPV-related diseases, which is particularly important for future healthcare professionals. We aim to examine the share of correct answers and the prevalence of different attitudes about the HPV vaccine among active regular students of the Faculty of Medicine in Novi Sad. Methods: A cross-sectional study was conducted from 1 to 30 November 2023 using a structured survey questionnaire. Results: A total of 1760 students were included, of which 78% were female, with an average age of 21 years. Students who participated in prior HPV education) demonstrated significantly higher knowledge (81.92% vs. 65.60%, p < 0.001) and were more likely to recommend the vaccine to patients (89.91% vs. 82.99%, p < 0.001). Almost all vaccinated students (99.41%) would recommend the vaccine, compared to 82.91% of unvaccinated students (p < 0.001). Students who actively sought HPV information also showed a higher likelihood of recommending the vaccine (93.05% vs. 83.02%, p < 0.001). Moreover, those with sufficient self-assessed knowledge were more inclined to recommend the vaccine (89.88%) than those with insufficient knowledge (81.66%, p < 0.001). The analysis demonstrated that an increase in the number of correct answers in the knowledge evaluation corresponds to higher odds of recommending the HPV vaccine to patients (OR = 1.23, 95% CI 1.17–1.28). Positive attitudes prevailed, with 68.89% supporting more education on HPV vaccination. Conclusions: Students who previously attended education on HPV infection/vaccination and those who would recommend the vaccine have significantly higher levels of knowledge. The study highlights the importance of HPV-related education in shaping future healthcare professionals’ attitudes and knowledge.

Hemp seed oil, obtained via the cold pressing of hemp seeds, is widely represented on the market. The objective of this study was to evaluate the fatty acid (FA) composition of hemp seed oil by means of nutritional quality indices. The FA profiles (37 FA) of 20 hemp seed oils marketed in several European countries were obtained using GC-FID and used for the calculation of lipid quality indices. As expected, considering the same plant source, FA profiles and the corresponding quality indices showed great similarity. Polyunsaturated to saturated FA ratio (PUFA/SFA) (6.8 ± 0.5) is used to assess the impact of diet on cardiovascular health (CVH) as PUFA can depress low-density lipoprotein cholesterol (LDL-C) and lower serum cholesterol levels, as opposed to SFA. Therefore, the higher PUFA/SFA ratio, the more positive the effect. Compared with this ratio, the hypocholesterolemic/hypercholesterolemic index (HH) (12.7 ± 0.8) may more accurately reflect the effect of FA composition on CVH. The index of atherogenicity (IA) (0.08 ± 0.005) is characterized by the main classes of SFA (which are pro-atherogenic, with the exception of C18:0) and unsaturated FA (which are anti-atherogenic). Therefore, foods with a lower IA can reduce the levels of total cholesterol and LDL- C in blood plasma. The index of thrombogenicity (IT) (0.11 ± 0.01) indicates the tendency of FA to form clots in blood vessels and provides the relationship between the pro-thrombogenic FA (C12:0, C14:0 and C16:0) and the anti-thrombogenic FA (MUFA, omega-3 and omega-6 FA). Thus, foods with a lower IT are beneficial for CVH. The unsaturation index (UI) (183.8 ± 5.1) represents the degree of unsaturation in lipids. Hemp oil showed advantages over sunflower and olive oils regarding PUFA/SFA (5.1 and 0.5, respectively) and IT (0.23 and 0.24), along with comparable IA (0.08 and 0.14), and substantially higher HH than olive oil (6.8). High UI indicates that unsaturated fatty acids abundantly present in hemp oil could easily undergo thermal degradation. Quality indices should be regarded as a valuable foundation for the valorization of hemp seed oil in nutritional recommendations.

Dietary fats, consisting of fatty acids (FAs), have diverse implications for disease prevention and treatment. Understanding the quality of dietary lipids is essential for managing chronic conditions and establishing food-based dietary guidelines. FAs naturally occur as mixtures of saturated (SFAs), monounsaturated (MUFAs), and polyunsaturated FAs (PUFAs), and their nutritional and medicinal values are evaluated using specific indices. This study aimed to assess the FA profiles and lipid quality indices of daily meals served in kindergartens located in Novi Sad, Serbia. During the autumn, winter, and spring seasons of the 2022/2023 year, meal (breakfast, snack, and lunch) sampling was conducted in a randomized manner on 15 unannounced days in each season. The nutritional composition and energy value of the sampled meals were determined, as well as their FA composition (GC-FID). The findings indicated that the average energy value of the daily meals met the recommendations of national regulations, as well as the daily fat intake, with a total fat intake amounting to 24.5 g/day during both the autumn and winter seasons and 23.4 g/day in the spring season. The predominant FAs were SFAs; their average intake was 11.9, 13.4, and 12.1 g/day during autumn, winter, and spring, respectively. MUFA intake exhibited minor variations across the seasons, with mean intakes of 7.8, 7.6, and 7.4 g/day, respectively. The highest mean PUFA intake was observed during autumn (4.8 g/day), while the winter and spring seasons displayed intakes of 3.5 and 4.0 g/day, respectively. Furthermore, regarding the lipid quality indices, the highest average values of PUFAs/SFAs, considered desirable, were identified during autumn (0.51 ± 0.31), whereas the lowest values were observed in winter (0.32 ± 0.27). The atherogenicity (IA) and thrombogenicity (IT) indices consistently exceeded the recommended value of one across all seasons, indicating an unfavorable lipid quality. The lowest IA (1.07 ± 0.66) and IT values (1.11 ± 0.49) were recorded during autumn. These results have significant implications for establishing national guidelines and nutrition standards, particularly for preschool-aged children, aiming to enhance health outcomes and mitigate the burden of chronic diseases on the healthcare system in the Republic of Serbia. Improving the lipid quality of meals provided in kindergartens can contribute to these objectives.
