Assessment of the Quality of Cause-of-Death Data in Serbia for 2005-2019 Vital Statistics Performance Index Estimation.

Background: We aimed to evaluate the quality of the cause of death (COD) concerning mortality patterns and completeness of death registration to identify areas for improvement in Serbia.

Methods: COD data collected from the mortality register in Serbia from 2005 to 2019 (1540615 deaths) were analyzed with the software Analysis of National Causes of Death for Action. The Vital Statistics Performance Index for Quality (VSPI(Q)) is estimated for the overall COD data quality.

Effects of Autoclave Sterilization on Cyclic Fatigue Resistance in 5 Types of Rotary Endodontic Instruments: An In Vitro Study.

BACKGROUND Rotary endodontic instruments are increasingly used in root canal treatment and have replaced stainless steel manual files. Cyclic fatigue is the cyclic loading of stress to produce deformation or fracture. This study aimed to evaluate and compare the effects of autoclave sterilization on cyclic fatigue in 5 types of rotary endodontic instruments.

Cancer of unknown primary - incidence, mortality trend, and mortality-to-incidence ratio is associated with human development index in Central Serbia, 1999-2018: Evidence from the national cancer registry.

Objectives: The aim was to estimate the trend of incidence, mortality and mortality-to-incidence ratio (MIR) in Central Serbia in 1999-2018 and its possible association with the human development index (HDI).

Methods: In this study, cancer of unknown primary (CUP) was included as C77-C80 codes. Trend analysis was performed in the Joinpoint Regression Programme version 4.

Influence of etching mode and composite resin type on bond strength to dentin using universal adhesive system.

Adhesive bond strength at the composite/dentin interface is influenced by various factors, including the etching mode and composite resin type. The purpose of this study was to evaluate the influence of the total-etch and self-etch mode on the microtensile bond strength (μTBS) of conventional and bulk-fill composite to dentin, using the universal adhesive system. Sixty non-carious human teeth were sectioned parallel to their longitudinal axis, using a low-speed diamond saw to obtain a flat dentin surface.

The predictive value of Klotho polymorphism, in addition to classical markers of CKD-MBD, for left ventricular hypertrophy in haemodialysis patients.

Purpose: Cardiovascular events are the major reasons for mortality in haemodialysis patients. Fibroblast growth factor 23 (FGF23), Klotho protein and G-395A Klotho gene polymorphism have been associated with effects on the cardiovascular system. Our study investigates the interrelationship between Klotho protein gene variations, mineral-bone metabolism and left ventricular hypertrophy in patients undergoing chronic haemodialysis programme.

Does short-term air pollution exposure have effects on blood pressure and heart rate in healthy women in the city of Niš, Serbia?

Objective: Epidemiological research has shown that air pollution is associated with cardiovascular events, but little is known about short-term effects on blood pressure (BP) and heart rate (HR) in Serbian population. The present study assessed the short-term association between black smoke (BS) and sulphur dioxide (SO) levels in urban air and the daily values of blood pressure and heart rate in 98 healthy nonsmoking female volunteers.

Methods: Generalized regression model was fitted controlling for temperature, relative humidity, air pressure, season, and the day of the week.

Impact of socio-demographic characteristics and long-term complications on quality of life in patients with diabetes mellitus.

Objective: Diabetes mellitus (DM) has been one of the leading chronic diseases worldwide over past decades. The objective of the study was to identify predictors associated with health-related quality of life (HRQOL) in diabetic patients.

Methods: A cross-sectional questionnaire-based study was conducted at the General Hospital of the city of Leskovac, between June and November 2015.

Progress of statistical analysis in biomedical research through the historical review of the development of the Framingham score.

Background: The interest in developing risk models in medicine not only is appealing, but also associated with many obstacles in different aspects of predictive model development. Initially, the association of biomarkers or the association of more markers with the specific outcome was proven by statistical significance, but novel and demanding questions required the development of new and more complex statistical techniques.

Methods: Progress of statistical analysis in biomedical research can be observed the best through the history of the Framingham study and development of the Framingham score.
