This study presents the results of continuous indoor radon measurements in a test-house in the vicinity of the “Trepča” mine, near the town of Kosovska Mitrovica. Annual measurements were performed using the detector, Airthings Corentium Home, in the bedroom of an old residential building. A high estimated annual effective dose from radon (33 mSv) was calculated using the last ICRP dose conversion factor and is discussed here regarding the previously recommended ones. There are significant indications concerning the health hazard. Several measures are proposed and serve as a technical solution including other effective, low-cost radon mitigation procedures in order to reduce radon levels. The effectiveness of the applied measures resulted in a 44% reduction in radon concentration.

Man is constantly exposed to radiation from the radionuclides from the environment. This study presents the results of measuring the absorbed dose rates of natural ionizing radiation in rural areas in the municipality of Štrpce, in southern part of Kosovo and Metohija. The measurements were conducted in 20 houses in two cycles: when rooms were not heated, and when they were warmed up in the same season. Ten observed houses were with basement rooms, and ten others were without basements. The absorbed dose rate of radiation was measured by Gaiger-Miller's counter DR-M3. Mean value of the measured absorbed dose rate was 1.93 µGy/h - in the first cycle and 1.47 µGy/h - in the second cycle. At the same time the values of the absorbed dose of radiation in the environmental were measured, and obtained values were 1.77 µGy/h and 1.33 µGy/h, respectively. Relations between absorbed dose in the premises and in the environment were 1.09 in first cycle, and 1.1 in the second cycle of measurements.

The results presented in this paper are part of the investigating of radon the concentrations from natural sources in the Toplica region. The results refer only to the radon concentrations in water from private captured wells at 12 locations. Radon concentration in water was measured by alpha spectrometry using the RAD 7 - RAD H2O system. The range of radon concentration is from (2.8±1.2) to (76.0±4.0) kBq/m3 , and the contribution of radon released from water to the air in the premises was in range (0.8±0.3) to (22.8±1.2) Bq/m3 . The annual effective doses of inhaled and ingested radon were determined, the mean values were (114.8±14.8) and (3.2±0.3) mSv/y.

Perinatal asphyxia (PA) is a condition in which there is a decreased or interrupted blood and oxygen supply to the tissues of the fetus, i.e., the newborn, immediately before, during, or immediately after delivery. It constitutes a significant cause of mortality, accounting for 23-24% of all neonatal deaths. The estimated global incidence of perinatal hypoxia is approximately 0.5% of the total number of live births at gestational age over 36 weeks. PA negatively impacts the entire organism, especially metabolically demanding tissues. Due to the sensitivity of the kidneys to oxygen deprivation, acute kidney injury (AKI) can develop within the first 24 hours of the ischemic episode. Prolonged ischemia may lead to irreversible cortical necrosis. Early recognition of AKI is crucial for adequate fluid and electrolyte replacement, as the action of pre-renal etiological factors is a dynamic process with a reversible onset. However, AKI represents a poor prognostic sign, with higher mortality in neonates who develop AKI after perinatal asphyxia, and up to 40% of survivors may have permanent kidney damage. Given the specificity of both the population and the clinical entity, there is a clear need for newer, more sensitive, and specific biomarkers of renal function. The aim of the paper was to review the most significant urinary biomarkers in neonates with perinatal asphyxia that could be crucial for early detection of renal impairment. Analysis of scientific and professional papers published in the last ten years in international scientific and professional journals available in the PubMed database. When considering a potential biochemical marker, the type of biological sample in which it is quantified is a crucial characteristic that must be taken into account. For newborns, obtaining a sample non-invasively is of utmost importance. In this context, urine analysis emerges as a good choice. Metabolites in the urine of PA patients have been proven significant for monitoring the renal function. Unfortunately, urine as a biological sample has the drawback that it cannot be obtained immediately after birth, and a significant number of neonates due to pre-existing renal damage may be anuric.

During the SARS-CoV-2 pandemic, there was a significant number of cases accompanied by thrombosis. The precise pathophysiological mechanism remains unclear. The importance of the fibrinolytic mechanism in maintaining physiological hemostasis led us to explore its potential contribution to COVID-19-induced thromboembolism. This study aimed to identify changes in the hemostasis at the time of admission of SARS-CoV-2-positive patients to the hospital and their influence on the disease outcome. The presented prospective study included 60, RT-PCR-confirmed patients hospitalized in the Covid units of the Clinical Center of Vojvodina. Platelet number, platelet aggregability, aPTT, PT, fibrinogen, D-dimer, and Euglobulin Clot Lysis Time (ECLT) were determined from blood samples. Participants were classified as those with preserved and suppressed primary hemostasis, those with physiological and increased thrombin activity, those with preserved and decreased fibrinolytic activity, and those with positive and negative disease outcomes. Results. Forty-four positive outcomes were observed (73.3%), while a negative outcome, including thromboembolic complications and death was present in 16 subjects (26.7%). Unconditional logistic regression revealed a mild negative influence of all investigated parameters on the disease outcome. For ECLT, OR was 1.084 with 95%CI 1.023 -1.160. The multivariate regression model showed that of all the investigated parameters, only ECLT was a significant predictor for negative outcome with a level of p < 0.001. The global assessment of the fibrinolytic mechanism is a useful predictor of disease outcome in SARS-CoV-2-positive patients at the moment of their admission to hospital.
