The objective of this study was to evaluate wild growing , , , and with respect to their essential oil (EO) content, composition and antimicrobial activity. The five species were collected at Mt. Rtanj and the village of Sesalac, Eastern Serbia. The main EO constituents of Lamiaceae plants were -cymene (24.4%), geraniol (63.4%) and germacrene D (21.5%) in , and ssp. , respectively. EO had multiple constituents with major ones being camphor (9.8%), caryophyllene oxide (6.5%), terpinen-4-ol (6.3%) and 1,8-cineole (5.6%), while the main EO constituents of were 1,8-cineole (45.1%) and camphor (18.2%). Antimicrobial testing of the EO showed that (Gram-positive) was more sensitive to all of the tested EOs than (Gram-negative). EO showed the highest antimicrobial activity against both tested bacterial strains. This is the first study to characterize the EO composition and antimicrobial activity of these five medicinal species from Eastern Serbia in comparison with comprehensive literature data. The results can be utilized by the perfumery, cosmetics, food and pharmaceutical industries, but also for healing purposes in self-medication.

Background: Understanding COVID-19 vaccine effectiveness (VE) in preventing severe disease is critical to inform vaccine policy. We used the test-negative design to estimate VE against SARS-CoV-2-confirmed hospitalisation in adults ≥18 years in the eastern WHO European Region.
Methods: We included patients hospitalised for severe acute respiratory infection (SARI) at sentinel surveillance sites in Albania, Georgia, Kyrgyzstan, North Macedonia, Serbia, and in Kosovo.

Pertussis resurgence has been documented even in countries with high pediatric vaccine coverage. The proportion of isolates not expressing pertactin (PRN) has increased in several countries where acellular pertussis (aP) vaccines are used. We systematically reviewed published literature up to July 2023 on PRN-negative isolates in MEDLINE and Embase with no geographical limitations, complemented with a gray literature search.

Objectives: Our objective was to explore how women living with HIV aged ≥40 years perceive their care in relation to their HIV infection, comorbidities, and menopausal health and to evaluate the extent to which the care they receive meets their expectations, comparatively across World Health Organization (WHO) European regions.
Methods: We conducted a cross-sectional survey (May-December 2023) among women living with HIV aged ≥40 years from the WHO European region. Five dimensions of care were assessed: content of care, information, relationship with caregiver, organization of care, and patients' rights and privacy, in addition to management of non-HIV comorbidities and menopause.

The objective of this study was to analyze the concentrations of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in infant food (infant formulas and human milk) collected in Serbia and to assess their exposure and associated health risks. A total of 101 PCB congeners and 26 PBDE congeners were analyzed. In infant formulas (IF), the total PCB levels averaged 63.

Background Context: Spondylodiscitis management presents significant clinical challenges, particularly in critically ill patients, where the risks and benefits of surgical intervention must be carefully balanced. The optimal timing of surgery in this context remains a subject of debate.
Purpose: This study aims to evaluate the effectiveness of early surgery versus delayed surgery or conservative management in critically ill patients with de novo pyogenic spondylodiscitis.
