Laboratory Puzzle of Oxidative Stress, Parameters of Hemostasis and Inflammation in Hospitalized Patients with COVID-19.

Bearing in mind that coronavirus disease (COVID-19) is associated with a wide range of laboratory abnormalities, the aim of this study was to examine the importance of determining the parameters of oxidative stress and antioxidant protection as well as markers of inflammation and hemostasis in hospitalized patients with COVID-19. The study population included 105 patients with severe COVID-19 and 65 healthy control subjects. The parameters of oxidative stress and the activity of enzymes of the antioxidant system were determined from the obtained samples using spectrophotometric methods.

Children's Internet use and physical and psychosocial development.

Introduction: Internet use (IU) commonly refers to sedentary lifestyle and may be addictive, especially among children. The aim of this study was to investigate the relationship between IU and some aspects of child physical and psychosocial development.

Methodology: We conducted a cross-sectional survey by using a screen-time based sedentary behavior questionnaire and Strengths and Difficulties Questionnaire (SDQ)-among 836 primary school children in the Braničevo District.

THE ROLE OF TUMOR-SEEKING RADIOPHARMACEUTICALS IN THE DIAGNOSIS AND MANAGEMENT OF ADRENAL TUMORS.

Context: The variety of tumor-seeking radiopharmaceuticals, which are currently in clinical use, may have a potential role as imaging agents for adrenal gland tumors, due to physiological characteristics of this organ.

Objective: The purpose of this study was to evaluate the diagnostic potential of Tc-HYNIC-TOC, Tc(V)-DMSA, and Tc-MIBI in the assessment of adrenal tumors, by correlating with imaging findings and histopathologic results.

Design: The research is designed as a cross-sectional prospective study.

Glucose and lipid abnormalities in patients with adrenal incidentalomas.

Unlabelled: Adrenal incidentalomas (AI), defined as masses detected during imaging procedures of non-adrenal disorders, have become a common clinical problem that appear to have impairment of glucose and lipid metabolism.

Patients And Methods: One hundred and ten patients (mean 53.5 age; 24-72), who were diagnosed with functioning and non-functioning AI, were assessed.
