Background and Objectives: This study primarily aims to evaluate the preoperative staging effectiveness of PET-CT in early-stage cervical cancer, particularly, its ability to detect primary tumors and micrometastases. Materials and Methods: In this retrospective study, cervical cancer patients who had undergone preoperative 18F FDG PET-CT scans and were treated at the Department of Gynecology, Institute of Oncology, Vojvodina, in Sremska Kamenica, during the period from 2016 to 2020 were analyzed. Results: The study included 62 patients (mean age, 49.3 ± 9.6 years). Squamous cell carcinoma was the predominant histological type (95.2%), with G2 differentiation (82.3%) and FIGO stage Ib1 (80.6%) being the most common. Assessed by 18F FDG PET-CT, the mean tumor size was 26.4 ± 10.8 mm, which is slightly lower than the 26.9 mm measured during clinical examination (p = 0.784), with a significant (r = 0.678, p < 0.001) correlation between these methods. 18F FDG PET-CT demonstrated an overall accuracy of 88.7% for identifying primary tumors, with a sensitivity of 86.8%, specificity of 100.0%, PPV of 100.0%, and NPV of 56.2%. An intraoperative examination showed identical overall accuracy but higher sensitivity (98.1%) and lower specificity (33.3%). For 18F FDG PET-CT, the level of agreement with the histopathological examination was good (Kappa 0.656), while for the intraoperative examination, it was moderate (Kappa 0.409). Regarding the lymph node assessment, 18F FDG PET-CT’s accuracy was 82.2%, with a sensitivity of 53.8% and a specificity of 89.8%. The intraoperative examination showed lower accuracy (66.1%) but higher sensitivity (76.9%). The 18F FDG PET-CT Kappa value indicated moderate agreement (0.449), while the intraoperative examination showed poor agreement (0.282). Conclusions: In conclusion, significant effectiveness is shown by 18F FDG PET-CT for preoperative staging of early-stage cervical cancer, offering superior accuracy in detecting primary tumors and micrometastases, particularly in predicting lymph node metastases, thereby enhancing diagnostic accuracy and informing treatment decisions.

Objectives. The main objective was to assess the relationship between sociodemographic and occupational factors and stress levels among healthcare workers in family medicine in Bosnia and Herzegovina, using the PSS-10-BH scale. Materials and Methods. A cross-sectional study was conducted using the PSS-10-BH questionnaire distributed via Google Forms to primary care nurses and physicians between July and August 2022. Results. The study included 272 participants, with a mean age of 44.7 (±10.55), predominantly women (86.8%) and physicians (58.8%). The mean PSS-10-BH total score for the sample was 21.26 (±6.77) ranging from 3 to 36. The linear regression model indicated male gender and older age showed an association with slightly lower stress levels. Marital status and the number of children showed a slight positive association with stress levels. Occupation (B=-3.068, 95% CI: -5.442 to -0.694, P=0.012) was associated with stress, with physicians tending to report lower stress levels compared to nurses. Years of work experience (B=0.060, 95% CI: -0.190 to 0.309, P=0.636), and patient load (B=0.082, 95% CI: 0.027 to 0.137, P=0.004) were associated with higher stress levels. The results suggest that work-related variables are significant predictors of stress levels as measured by the PSS-10-BH scale in this sample of healthcare workers. The included predictors explain 10% of the variability in the outcome, indicating additional unidentified contributing factors. Conclusion. Occupational factors, particularly profession, work experience, and daily patient load, significantly influence stress levels in healthcare workers. Further research is needed to explore other potential influences and refine interventions aimed at managing stress in this population.

This paper deals with the problem of the relationship between young people's life satisfaction and their material condition, locus of control, attitude towards studying, attitude towards work and life orientation. The concept of life satisfaction and other correlates mentioned in the paper are certainly current in psychology and have been increasingly researched lately. It is very important to investigate the life satisfaction of young people and other correlates that contribute to life satisfaction, and to observe them all together through the prism of positive psychology. In this paper, we investigated what kind of relationships exist between the life satisfaction of young people and their material condition, their locus of control, attitude towards studies and work, and life orientation. Appropriate measuring instruments were applied to a sample of N=260 respondents (M=1.63, SD=.482). A scale for assessing life satisfaction, a scale for testing locus of control, a scale for attitudes towards studying, a scale for attitudes towards work and a life orientation scale, as well as a questionnaire for collecting appropriate sociodemographic characteristics. The scales that were used in the research showed appropriate metric characteristics of 0.87 for life satisfaction and locus of control, 0.78 for attitude towards studying, while slightly lower values for attitude towards work were 0.48 and life orientation 0.49. .The results of the research showed that there is a statistically significant positive correlation between life satisfaction of young people and satisfactory material condition (r=0.316, p=0.00) and between life satisfaction and locus of control (r=0.208, p=0.001). However, there is no statistically significant correlation between young people's life satisfaction and attitudes towards studying (r=0.107, p=0.091). As for the life satisfaction of young people and attitude towards work, there is a negative correlation between these variables (r=-0.201, p=0.001) and there is a positive correlation between life satisfaction and life orientation (r=0.456, p=0.000).

Abstract Duplication of the vermiform appendix is a rare anomaly observed in patients undergoing appendectomy. A 27-month-old male toddler presented with a 9-day history of abdominal pain, vomiting, and diarrhea, progressing to an acute abdomen with signs of severe peritonitis. Intraoperative findings revealed a periappendicular infiltrate from a perforated vermiform appendix of the tenia coli type. A second, inflamed appendix was incidentally discovered in its typical location during the procedure. Vermiform appendix duplication presents a clinical challenge due to its rarity and potential for complications. According to the Cave–Wallbridge classification, this case represents Type B2, or the tenia coli variant, characterized by a perforated appendix originating at the tenia coli convergence and a smaller, secondary appendix in a retrocecal position. This case emphasizes the importance of thorough distal and proximal exploration during initial appendectomy when this anomaly is suspected, particularly in cases of Type B2.

Hydropower is the world's most exploited renewable energy source. It provides a substantial, flexible, and reliable source of renewable energy, complementing other renewables like solar and wind power. Besides conventional hydropower potentials and technologies, the development of technologies for the exploitation of hidden hydropower potentials is an ongoing process. This paper presents the current state of hidden hydropower technologies and links them with possible applications in different hydropower potentials. Technologies and potential applications are structured within three main groups (pressurized systems, hydro storage, unpressurized systems), with their mutual interconnections analysed and displayed throughout the paper. The opportunity for the application of hidden hydropower technologies in different roles within the energy system is recognized through the concepts of off- and on-grid roles, the prosumer concept, and on-site measurement powering. This paper shows that hidden hydropower technologies could emerge as significant contributors to a smoother energy transition, especially with the prosumer and off-grid concepts.
