Objectives: There is insufficient evidence regarding the potential risk of mobile phone use on mental health. Therefore, the aim of this research was to examine the relationship between mobile phone use and mental health by measuring the levels of depression, anxiety, and stress among university students in Serbia and Italy. Methods: This cross-sectional study was carried out at two distinguished universities in Serbia and Italy from March to May of the 2015/2016 academic year and included 785 students of both genders. The questionnaire was compiled and developed from different published sources regarding the manner and intensity of mobile phone use, along with the Depression Anxiety Stress Scale (DASS 42) for measuring psychological health. The statistical analysis of the data included the application of binary logistic regression and correlation tests. Results: Statistical analysis indicates that anxiety symptoms are somewhat more present in younger students (odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.76–0.96), in those who send more text messages (SMSs) (OR = 1.15, 95% CI: 1.11–1.31), and in those who browse the internet less frequently (OR = 0.84, 95% CI: 0.73–0.95). Stress is more common in students who make fewer calls a day (OR = 0.79, 95% CI: 0.64–0.97), as well in those who spend more time talking on the mobile phone per day (OR = 1.28, 95% CI: 1.12–1.56). The strongest predictor of high stress levels was keeping the mobile phone less than 1 m away during sleeping (OR = 1.48, 95% CI: 1.12–2.08). Conclusions: The results indicated that the intensity and modality of mobile phone use could be a factor that can influence causal pathways leading to mental health problems in the university student population.

Our results showed that both socioeconomic and chronic complications are relevant factors of HRQOL in type 1 and 2 diabetes mellitus patients. Age, rural lifestyle, retirement, lower level of education and low socioeconomic status, as well as DM complications (angina pectoris, hearth failure, diabetes nephropathy, and diabetes retinopathy) were found to be independent risk factors for the component scores of SF-36 and EQ-VAS score. Taking into consideration the results obtained, health practitioners should be aware not only of the clinical parameters of patients with DM, but also of their educational level and working status.
Cardiovascular risk factors are present in the final-year students of the School of Medicine, University of Nis. It is necessary to insist on decreasing obesity prevalence, cigarette and alcohol consumption, and on increasing physical activity of students in order to prevent cardiovascular diseases.
Primary colorectal lymphoma is a rare malignant tumor of the large bowel. Therapy usually involves resection of the affected colon or rectum and regional lymphovascular structures, followed by adjuvant therapy. Survival period is short and, therefore, timely diagnosis is crucial in early disease stages when the probability of cure is high.
According to the observed inaccuracy of indirect measurement, we recommended the use of a correction factor for calculation of both Gn-IdD and Gn-CoD real vales, in defining of parametric model of the "standard mandible" based on indirect morphometry on 2D reconstructions of mandibular MSCT scans. Additional studies with larger number of specimens and quantification of anatomical variations regarding to sex, age, dentition status and ethnic origin, additionally should increase measurement accuracy and consequently reliability of future parametric model of the human mandible.
The aims of this study were to review the clinical presentation of non-Hodgkin's lymphomas of the large bowel, to analyze the prognostic factors using univariate and multivariate methods, as well as the overall survival. We identified 24 cases at our clinic between 1991 and 2005, based on pathohistological analysis and standard diagnostic criteria established by Dawson et al. They accounted for 1.2% of all cases of the large bowel malignancies (24/2021) during this period. The following clinical information such as age, gender, symptoms, tumor localization, operation performed, histology grade, stage of disease, and adjuvant chemotherapy was obtained. Survival function was expressed by Kaplan-Meier curve and Log-rank test was performed for the difference in survival between two patient groups. Multivariate analysis was carried out using the Cox proportional hazard model. Overall mean survival time was 41.91 months. According to the univariete analysis, the factors influencing overall survival rate was operation type (elective and emergent). Tumor stage and operation type were independent prognostic factors for survival, as determined by multivariate analysis. Our results showed that tumor stage and operation type should be considered as the most important prognostic factors in patients with primary non-Hodgkin's lymphomas of the large bowel.
Renalase was shown to be strong predictor of decreased glomerular filtration rate and was significantly higher in the group of patients on cyclosporine. Endothelial nitric oxide synthase was identified as a strong protective factor for kidney function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
