Purpose: The purpose of this cross-sectional study was to determine the frequency of depressive symptoms in patients with epilepsy (PWE) in a tertiary epilepsy center and to analyse possible predictors of depression in several domains, including clinical characteristics of epilepsy and sociodemographic factors.

Methods: PWE patients who visited our epilepsy clinic during the 6th month in 2020 and 2021 were enrolled in our study. To collect the data, structured scales were created for the clinical characteristics of the disease and for the sociodemographic data.

(1) : The COVID-19 pandemic has brought about a change in the concept of teaching with the introduction of online lectures and "distance learning." The aim of this study was to determine the impact of the COVID-19 pandemic on the confidence and both theoretical and practical knowledge of dental students regarding the courses in conservative dentistry and endodontics. (2) : The study was conducted using an originally created online questionnaire consisting of 30 questions that the students used to make a subjective assessment of their confidence in performing both endodontic and conservative procedures using numerical scales.

Article Synopsis
  • Hepatitis C virus (HCV) infection can lead to serious liver disease and is often associated with extrahepatic manifestations, including neurocognitive disorders that affect attention and memory.
  • This study aimed to investigate the relationship between neurocognitive function and various laboratory parameters in patients with untreated, non-cirrhotic HCV, focusing on inflammation, liver function, and mixed cryoglobulinemia.
  • Although initial results showed some correlations between neurocognitive results and laboratory measures, all significant correlations vanished after adjusting for multiple comparisons, suggesting the need for further research to validate these findings.

Background: Breech presentation (BP) results from at random filling of the intrauterine cavity, with an equal probability for a BP or cephalic presentation (CP). Each fetus in BP has its "pair" in CP randomly assumed CP. Direct comparison of BP and CP makes bias to less expressed differences between these two groups.

Objective: The purpose of the study was to evaluate pain thresholds, impairment of the endogenous pain modulatory system, and self-reported cognitive-emotional and central sensitization-related symptoms among three subject groups: a rarely studied patient cohort with neuropathic pain from lumbosacral radiculopathy (NPLSR), patients with fibromyalgia (FM) and healthy controls (HC).

Methods: Patient-reported pain-related symptomology was evaluated with psychometricallyvalidated questionnaires. Pressure pain threshold (PPT), heat pain threshold (HPT), and cold pain threshold (CPT) were assessed in the low back and contralateral forearm.

Epigenetic modifications of the membrane bound catechol-O-methyltransferase (-) gene may affect the enzymatic degradation of dopamine, and consequently, human behavior. This study investigated the association between membrane bound catechol-O-methyltransferase DNA methylation (DNAm) differences in 92 monozygotic (MZ) twins with phenotypic manifestations of cognitive, behavioral, and personality indicators associated with reward-related behaviors and lack of control. We used pyrosequencing to determine DNAm of the regulatory region of membrane bound catechol-O-methyltransferase in saliva DNA.

Child engagement refers to the time spent interacting with physical and social environments according to age, abilities, and a situation. The aim of this study is to assess the functioning of children in early childhood routines using engagement assessment instruments relative to the presence of developmental disabilities, age, gender, and parental characteristics within the contexts of preschool and family routines. The sample comprised 150 children aged 3-5 (AS = 4.

Executive functions (ЕF) are complex cognitive processes that govern our behavior and thoughts. Associations between personality traits and executive functions clarify the mechanisms of a person's ability to function in everyday situations. The main goal of this study was to explore different personality dimensions relevant to the prediction of two different executive functions - Inhibition and Working Memory.

Objectives: We assessed the prevalence of the use of new anti-seizure medications and valproate in the female population over two decades.

Materials And Methods: We conducted a retrospective observational cross-sectional study of medical records of children and adolescents (4 - 19 years old) with newly diagnosed epilepsy in a tertiary clinical center in Serbia from 1997 to 1999 and 2017 to 2019.

Results: The statistical analysis revealed significant changes in the treatment of generalized and focal seizures and all etiologies of epilepsy.

Objective: The main goal of this study was to explore the latent structure and genetic basis of cognitive processes involved in the Wisconsin Card Sorting Task (WCST) within phenotypic, behavioral genetic, and molecular genetic research paradigms.

Method: The sample used in phenotypic and behavioral genetic analyses comprised 468 twins (154 monozygotic and 80 dizygotic twin pairs), while molecular genetic analyses were performed on 404 twins from the same sample. The zygosity of most twin pairs (96.

Executive function (EF) skills involve higher-level cognitive functions, such as planning, goal formation, goal-directed behavior, and effective performance. Previous research has shown that these aspects of EF are essential for successful functioning in everyday life. This study aimed to examine differences in the behavioral aspects of EF between young adults with epilepsy and healthy controls.

Background: In HIV negative population metabolic syndrome and steatosis are related to poorer neurocognitive (NC) performance. We investigated if similar relation exists in people living with HIV (PLWH).

Methods: We included male PLWH aged 20-65, with undetectable viral load for at least 6 months.

The first twin study in Serbia began in 2011 as a part of the research project, 'Psychological Foundations of Mental Health: Hereditary and Environmental Factors'. At the same time, the research team from the Faculty of Philosophy and Faculty of Medicine in Novi Sad established the first Serbian twin registry. The registry is intended primarily for the purpose of the research in behavioral genetics, as well as potential future studies in human genetics.

Backgrounds: Even though epilepsy is the most common neurological disorder in adolescence; studies of adolescents with epilepsy are scarce.

Objective: To evaluate whether adolescents with epilepsy are more likely to develop anxiety and depressive symptoms than their healthy peers and to determine the relationship of depression and anxiety scores to epilepsy-related variables.

Settings And Design: Cross-sectional observational study.

The need for a research and practical tool, such as a short, reliable, and valid personality assessment test, suggests researchers to create shortened versions of original instruments. Reinforcement sensitivity questionnaire (RSQ) was created in line with some basic premises of revised Reinforcement sensitivity theory, which proposes three motivational and emotional systems: Behavioral inhibition system (BIS), responsible for scanning environment for potential threats, Behavioral activation system (BAS), responsible for aproaching behavior, and the Fight/Flight/Freeze system (FFFS), responsible for behavior in the present threat. RSQ comprises five scales: BIS, BAS, Fight, Flight, and Freeze.

The advent of combined antiretroviral therapy (cART) has prolonged the life expectancy of HIV + individuals and decreased the incidence of HIV-associated dementia. However, milder forms of neurocognitive impairment remain common and are often associated with poor daily functioning and lower medication adherence. This paper presents a research aimed at exploring the cognitive status differences between HIV + subjects (N = 39) on cART therapy and a group of demographically comparable healthy subjects (N = 39) in Serbia.
