Background and Objectives: Smartphone use has been rapidly increasing worldwide, which has brought possible smartphone addiction into the focus of research. In order to identify potential smartphone addicts, several scales were developed to assess smartphone addiction. Among them, the Smartphone Addiction Scale was frequently used. The study aimed to test the reliability and validity of the Serbian version of the SAS-SV and estimate smartphone addiction prevalence among medical students. Materials and Methods: The study was conducted in December 2018 on a convenience sample of 323 third-year medical students. The cross-cultural adaptation was performed following the well-established guidelines for cross-cultural adaptation of self-reported measures. Exploratory factor analysis was used to examine the structure of the questionnaire. Factor extraction was performed by principal component analysis with Varimax rotation. For test–retest reliability, students completed the questionnaire twice within seven days. Results: The Serbian version of the SAS-SV showed good internal consistency (Cronbach’s alpha = 0.89) and excellent reliability for test–retest scores (ICC = 0.94, 95% CI = 0.92–0.96). Factor analysis supported the extraction of one factor, which explained 51.538% of the variance. To explore convergent validity furthermore, the SAS-SV was correlated with time indicators of smartphone use. According to cut-off values for the SAS-SV score, 19.5% of students could be regarded as “addicted”, and often spent more time on smartphones and social networks on working days and weekends than “not addicted” students. Conclusions: The Serbian version of the SAS-SV is a reliable and valid instrument for detecting smartphone addiction among university students. Further research on this issue is encouraged to enable a better understanding of this ever-increasing public health issue.

Background: In recent years, the need for validated and reliable questionnaires for different applications could be observed throughout scientific literature. To add to this trend, we translated into Serbian the Smartphone Addiction Scale-Short Version (SAS-SV) and tested it for its psychometric properties. This study's main aims were to test the Serbian version of the SAS-SV's internal consistency and reliability and estimate smartphone addiction prevalence among medical students. Methods: The study was conducted in December 2018 on a representative sample of third-year medical students. The cross-cultural adaptation was performed following the well-established guidelines for cross-cultural adaptation of self-reported measures. For test-retest reliability, students filled the questionnaire twice, within seven days. Results: The Serbian version of SAS-SV showed good internal consistency (Cronbach's alpha = 0.89) and excellent reliability for test-retest scores (ICC = 0.94, 95% CI = 0.92-0.96). Factor analysis supported the extraction of one factor, which explained 51,5% of the variance. To explore construct validity furthermore, SAS-SV was correlated with time indicators of smartphone use. According to cut-off values for the SAS-SV score, 19.5% of students could be regarded as “addicted” and often spent more time on smartphones and social networks on working days and weekends than “not addicted” students. Conclusion: The SAS-SV in the Serbian version is a reliable and valid instrument for detecting smartphone addiction among university students. Further research on this issue is encouraged to enable a better understanding of this ever-increasing public health issue.

Background/Aim. The incidence of postoperative delirium (POD) after non-cardiac surgery is a problem often not recognized by many anesthesiologists. The objective of our study was to detect POD and its possible cause, in patients undergoing Radical Retropubic Prostatectomy (RRP) under general anesthesia. Methods. After Ethical Committee approval, we enrolled 80 patients, ASA status II, in a prospective study, who were scheduled to undergo RRP under general anesthesia. All patients completed MMSE tests Iako veće intraoperativno krvarenje i postoperativni bol višeg intenziteta nisu uticali na učestalost pojave delirijuma, snižavali su MMSE skorovi, što ukazuje na značaj adekvatnog intraoperativnog tretmana pacijenta u toku hirurgije i anestezije u cilju smanjenja rizika za razvoj POD. Ključne reči: postoperativni delirijum, konzumiranje alkohola, intraoperativno krvarenje, postoperativni bol, radikalna retropubična prostatektomija.

Urosepsis is defined as sepsis caused by urinary tract infection (UTI). Urosepsis represents a quarter of all cases of sepsis in adults. Complications of UTIs are the most common risk factor for urosepsis development. These infections, especially pyelonephritis, often occur in patients with structural or functional malformations that interfere with normal urine flow. The problem of a significant increase in UTIs with multiresistant bacteria should be emphasized, especially in patients with recurrent UTI and their frequent treatments. As the urogenital tract is one of the most common sources of infection in sepsis in general, a detailed assessment of the tract should be carried out in all septic patients. Even though urosepsis is associated with a relatively good prognosis and lower mortality than sepsis of another etiology, it occurs rapidly and progresses at a significant speed. Since urosepsis is mainly the result of obstruction of the urinary tract, the development of septic shock can most often be prevented by implementing early deobstruction. Knowledge of the most common causes of urosepsis and the category of high-risk patients will provide clinicians with the tools with which to prevent its occurrence.
