Using machine learning algorithms and techniques for defining the impact of affective temperament types, content search and activities on the internet on the development of problematic internet use in adolescents' population.

Background: By using algorithms and Machine Learning - ML techniques, the aim of this research was to determine the impact of the following factors on the development of Problematic Internet Use (PIU): sociodemographic factors, the intensity of using the Internet, different contents accessed on the Internet by adolescents, adolescents' online activities, life habits and different affective temperament types.

Methods: Sample included 2,113 adolescents. The following instruments were used: questionnaire about: socio-demographic characteristics, intensity of the Internet use, content categories and online activities on the Internet; Facebook (FB) usage and life habits; The Internet Use Disorder Scale (IUDS).

Healthcare Professionals' Knowledge and Behaviors Regarding Drug-Dietary Supplement and Drug-Herbal Product Interactions.

Given the widespread use of dietary supplements (DS) and herbal products (HP), healthcare professionals (HCPs) will increasingly encounter patients who use these preparations with conventional drugs and who need their services to reduce the consequences of adverse therapeutic outcomes. The aim of our survey was to assess the knowledge and behaviors of HCPs regarding the risk of potential drug−dietary supplement (DDSIs) and drug−herbal product (DHPIs) interactions. This cross-sectional survey collected data via on paper-based questionnaire among general practitioners (GPs) (n = 105), specialty doctors (n = 87) and nurses (n = 154).

Effects of problem-based learning modules within blended learning courses in medical statistics - A randomized controlled pilot study.

Problem-based learning (PBL) allows students to learn medical statistics through problem solving experience. The aim of this study was to assess the efficiency of PBL modules implemented in the blended learning courses in medical statistics through knowledge outcomes and student satisfaction. The pilot study was designed as a randomized controlled trial that included 53 medical students who had completed all course activities.

The Development of Temperament Evaluation of Memphis, Pisa, Paris, and San Diego - Auto-questionnaire for Adolescents (A-TEMPS-A) in a Serbian Sample.

Background: Previous studies suggest that temperament features of adolescents may be good predictors of the development of future psychopathology in this population. The aim of the study was to adapt the content and validate the psychometric properties of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego - Auto-questionnaire in a sample of Serbian adolescents.

Subjects And Methods: The sample included 2113 adolescents, 56% girls and 44% boys, average age 16.

Analysis of expired medications in Serbian households.

Introduction: An ongoing issue of expired medications accumulating in some households is a universal problem around the world. The aim of the study was to investigate the extent and structure of expired medications in Serbian households, and to determine which therapeutic groups generated the most waste.

Methods: This was an observational, cross-sectional study conducted in households in the city of Novi Sad, Serbia.

The Burden of Gastroesophageal Reflux Disease on Patients' Daily Lives: A Cross-Sectional Study Conducted in a Primary Care Setting in Serbia.

Introduction: Recent data from the studies conducted in the Western countries have proved that patients with gastroesophageal reflux disease have significantly impaired health-related quality of life compared to general population.

Objective: The study is aimed at evaluating the burden of reflux symptoms on patients'health-related quality of life.

Methods: The study involved 1,593 patients with diagnosed gastroesophageal reflux disease.

Analysis of the factors influencing development of urinary tract infections in patients with spinal cord injuries.

Background/aim: Urinary tract infections are still the most frequent complications in patients with spinal cord injury (SCI). The aim of this study was to analyze the factors influencing development of urinary tract infections during rehabilitation in patients with SCI.

Methods: This retrospective case/control study including 540 patients with SCI which were rehabilitated in the Clinic for Rehabilitation "Dr Miroslav Zotović" between January 2000 and December 2009.

Improving Education in Medical Statistics: Implementing a Blended Learning Model in the Existing Curriculum.

Background: Although recent studies report on the benefits of blended learning in improving medical student education, there is still no empirical evidence on the relative effectiveness of blended over traditional learning approaches in medical statistics. We implemented blended along with on-site (i.e.

Distribution and mobility of heavy elements in floodplain agricultural soils along the Ibar River (Southern Serbia and Northern Kosovo). Chemometric investigation of pollutant sources and ecological risk assessment.

This work investigates the influence of a high-magnitude flood event on heavy elements (HEs) pollution and mobility in the agricultural soils along Ibar River in Southern Serbia and Northern Kosovo. The study area was one of the most important Pb/Zn industrial regions in Europe. Soil samples (n = 50) collected before and after the floods in May 2014 were subjected to the sequential extraction procedure proposed by the Community Bureau of Reference (BCR).

Meta-analysis of the changes in correlations between depression instruments used in longitudinal studies.

Background: Correlations between instruments measuring the same construct reflect their concurrent validity. Little is known about changes in correlations between such instruments employed in studies with repeated assessment. The aim of this meta-analysis was to examine the changes in correlations between depression instruments in the course of longitudinal studies.

Analysis of the factors influencing functional outcomes in patients with spinal cord injury.

[Purpose] The extent of functional independence ultimately achieved by an individual patient will be influenced by a variety of medical and non-medical factors. [Subjects and Methods] this study included 419 patients with spinal cord lesions treated in the Clinic for Rehabilitation "Dr M. Zotovic", Belgrade, Serbia, from January 2000 to December 2009.

[Morbidity patterns of workers employed in pharmaceutical-chemical industry].

Introduction: Work in pharmaceutical-chemical industry is characterized by exposure to numerous hazards, both physical (microclimate, illumination, noise) and chemical (organic solvents). Organic solvents can cause damage to many organic systems and have carcinogenic, teratogenic and mutagenic effects.

Objective: The aim of this study was to analyze patterns of chronic morbidity of workers employed in pharmaceutical-chemical industry during 2002.
