The importance of timely ophthalmologic examination in preterm infants at risk of retinopathy occurrence

Background/Aim. Retinopathy of prematurity (ROP) is a multifactorial disease in premature infants. The aim of this study was to determine the incidence of ROP in children treated at the Center of Neonatology, Pediatric Clinic, Clinical Center in Kragujevac, Serbia. Methods. The study covered all children with birth weight below 2,000 g and/or gestational age below the 37th week, who from June 2006 to December 2009 underwent ophthalmological examination for ROP. The results of fundoscopy were classified in accordance with the International Classification of ROP. The treatment of infants and those with ROP was conducted in accordance with the early treatment of ROP study recommendations. We analyzed gestational age, birth weight and postconceptional age in two groups: healthy infants and those with severe form of ROP. Statistical analysis was performed using the SPSS 16. Results. A total of 478 children met the criteria of screening for ROP. Severe stage of ROP, which required laser treatment, had 102 (21.3%) children. Out of the infants with severe ROP 14 (13.7%) of the infants with APD had aggressive posterior disease, while two (0.4%) remained blind. The differences in the mean values of gestational age between the healthy and the children with severe form of the disease were statistically significant (p < 0.0005). The mean value of gestational age for the healthy children was 33.33 ± 2.28 weeks and for the seek infants 30.66 ± 2.79 weeks. The mean value of the weight in healthy children was 1.981 ± 407 g, and in sick children 1.535 ± 434 g which was statistically significant (p < 0.0005). Multivariate binary logistic regression showed that the occurrence of the disease depends on body weight and gestational age. Conclusion. The incidence of severe forms of ROP was 21.3%. Aggressive form of ROP was present in 13.7% of the children. The cut-off value for body weight was 1.740 g, and for gestationl age 32.5 weeks

Ex-ante assessment of air quality in EUSALPS and EUSAIR macro-regions: Towards a coordinated science-based approach in support of policy development

The study focuses on the air quality issues of the EUSALP and EUSAIR macro-regions and discusses areas for improvement to be considered in the development of their future strategies. Key areas where action is expected to be most effective, considering the particular features of the macro-regions, are those of residential heating, traffic and shipping emissions. A strengthened collaboration at the macro-regional level, especially between EU and non-EU countries, has the potential to boost environmental policies by promoting collaboration and exchange of best practices among cities and regions that face similar challenges.JRC.C.5-Air and Climat

The role of biochemical markers as early indicators of cardiac damage and prognostic parameters of perinatal asphyxia

Background/Aim. In recent years, the focus of interest of the scientific community is the application of heart markers as early indicators and prognostic parameters of perinatal asphyxia (PA). The aim of this study was to evaluate the significance of clinical application of heart markers in term newborns with perinatal asphyxia. Methods. During a 3- year period we analyzed 91 full-term newborns (55 with and 36 without perinatal asphyxia). In all the subjects within the first 24-48 h after birth, we simultaneously determined serum concentrations of cardiac troponin I, brain natriuretic peptide, MB fraction of creatine kinase (CK-MB) and Creactive protein. Results. In the group of full-term neonates with PA significantly higher levels of cardiac troponinI (p = 0.000), CK-MB fraction (p = 0.000), brain natriuretic peptide (p = 0.003) and C-reactive protein (p = 0.017) were found, compared to the group of healthy full-term newborns. In merged group (n = 91) cardiac troponin I level correlated with the fifth minute Apgar score (r = - 0.637, p = 0.000) and the serum lactate concentration in the first 12h after birth (r = 0.529, p = 0.000). Early increase in cardiac troponin I > 0.135 μg/L predicted the risk of death with the sensitivity of 84.6% and specificity of 85.9%, while the increase in CK-MB fraction, brain natriuretic peptide and C-reactive protein did not have a predictive value with respect to a mortality outcome. Conclusion. Among the tested cardiac markers, cardiac troponin I is the most sensitive and the only reliable early predictor of mortality in fullterm neonates with perinatal asphyxia

Potrebe ozime pšenice za vodom obračunate CROPWAT 8.0 modelom i metodom vodnog bilansa u uslovima južne Srbije

The experimental investigation through field trials has been carried out in the river valley of Južna Morava, municipality of Merošina, on the alluvium soil type, during the period 2009-2011. Water used on evapotranspiration of winter wheat (289.5-410.7 mm) was measured by water balance method. Considering average for both investigated years, the highest grain yield of winter wheat was observed at the variant with pre-irrigation soil moisture 70% of FWC (7110 kg ha-1 and 7480 kg ha-1), so measured values of ET at this variant from 381.1 to 393.1 mm represent potential evapotranspiration (ETP) of winter wheat in southern Serbia. Calculated demand for water of winter wheat (ETc) by CROPWAT model for the season 2009/10 was 409.9 mm, while in the season 2010/11 calculated water consumption amounted 432.6 mm of water.Eksperimentalna istraživanja poljskim ogledom u uslovima navodnjavanja obavljena su u dolini reke Južna Morava, na aluvijalnom zemljištu u periodu 2009- 2011.
