This article presents the third part of data on selected new and noteworthy taxa ensuing from the revision of Herbarium collection of the Institute for Nature Conservation of the Vojvodina province (PZZP). Selected taxa include 11 species, three subspecies, three varieties, one infraspecific taxon with indetermined status [stat. indet.] and one nothospecies placed within seven genera (Filago L., Ludwigia L., Luzula DC., Lycopus L., Lythrum L., Phlomis L. and Silene L.). Two varieties (Luzula campestris subsp. campestris var. elata, Silene flos-cuculi subsp. floscuculi var. latifolia) and one infraspecific taxon with indetermined status (Luzula multiflora subsp. multiflora [stat. indet.] b. uliginosa) are new for a flora of Serbia. Additionally, one species (Ludwigia palustris) and one nothospecies (Lythrum ×scabrum) are confirmed for Serbia.

This paper presents new records and noteworthy data on the following taxa in SE Europe and adjacent regions: the diatom alga Eunotia boreoalpina; the saprotrophic fungus Clitocybe truncicola; the liverwort Haplomitrium hookeri; the moss Leptodon smithii: the monocots Epipactis purpurata, Stipa tirsa, Typha laxmannii and T. shuttleworthii; and the dicots Krascheninnikovia ceratoides, Polygonum albanicum and Sorbus latifolia.

Leaf and shoot characteristics of the following four European barberry taxa from the Balkan Peninsula and Sicily were investigated in the present study: Berberis croatica, B. vulgaris, B. aetnensis and B. cretica. Analyses were based on 10 populations of B. croatica, five of B. vulgaris and two populations of both B. aetnensis and B. cretica. Populations were randomly selected within the natural distribution area of these species. Eight leaf traits, three shoot traits and the blade length/width ratio were analysed. Multivariate analysis (principal component analysis, canonical discriminant analysis and cluster analysis) distinguished B. cretica and B. aetnensis populations and, to a lesser extent, the populations of B. croatica and B. vulgaris. ANOVA showed that the analysed populations of both B. aetnensis and B. cretica were homogeneous within the species. All populations of both B. croatica and B. vulgaris showed different degrees of intraspecies variability. Lack of complete separation, the observed grouping of populations and high intraspecies variability in B. vulgaris and B. croatica may reflect the fact that the sampled B vulgaris and B.croatica populations were located at environmentally variable sites (unlike B. aetnensis and B. cretica), resulting in high phenotypic plasticity in those populations. Even though the observed patterns of morphological variation support the idea of four barberry taxa on the Balkan Peninsula and in Sicily, because of suspected adaptive phenotypic plasticity of the analysed Berberis taxa, the true taxonomic status of these taxa needs to be additionally confirmed by molecular methods.

Background/Aim: The World Health Organization (WHO) declared the spread of a novel disease COVID-19 as a pandemic on 11 March 2020. As of 12 June, there have been more than 7.4 million COVID-19 cases and more than 418,000 COVID-19 deaths globally. This paper represents epidemiological analysis of the first 100 days of COVID-19 epidemic in the Republic of Srpska. Methods: Data of all COVID-19 cases confirmed in the Republic of Srpska between 4 March and 12 June were collected from epidemiological and laboratory testing reports obtained from the Public Health Institute of the Republic of Srpska. This cross-sectional analysis was carried out on a sample of 1,607 laboratory-confirmed COVID-19 cases, which included: summary of patient characteristics, examination of age distributions and sex ratios, calculation of case fatality and mortality rates, incidence rates analysis, epidemiological curve construction and subgroup analysis. Results: Over 100 days after the first case was confirmed, the total number of infected patients in the Republic of Srpska rose to 1,607 (31,471 persons had been tested). As of 12 June, 69.9 % of those cases has recovered. During that period there were 117 confirmed deaths (average age 72 years; 60.7 % males; 86 % older than 60 years; 94 % with at least one comorbidity). The sex ratio among the confirmed cases was 0.95:1 (48.7 % men vs 51.3 % women). Infections were less common in persons below 20 years of age (7.3 % of all confirmed cases) and the majority of the affected persons were in the group 40-69 years of age. As much as 86 % of all death cases occurred in persons older than 60 years (average age 72 years) and 94 % of all death cases had at least one underlying condition (mostly cardiovascular diseases, 79.5 %). Conclusion: Evaluating the clinical data of COVID-19 patients, finding the source of infection and studying the behavior of the disease is crucial for understanding of the pandemic.

Objective – The aim of the paper is to present a rare and complex congenital heart defect (CHD), congenitally corrected transposition of the great arteries of the heart (ccTGA) with associated anomalies, including ventricular septal defect (VSD), valvular and subvalvular pulmonary stenosis, dysplasia of the tricuspid valve, and atrial septal defect (ASD) with first-degree atrioventricular block, which was diagnosed, monitored and successfully treated with heart surgery in an infant. Case Report – A female infant was born with 3350 grams in weight, 50 cm in length, oxygen saturation of 98%, and heart rate of 170 beats per minute. The antenatal and perinatal period was normal. CHD was verified by ultrasound at the age of 3 days. Angiotensin-converting-enzyme inhibitors (ACE inhibitors) and diuretics were introduced in therapy after one month. Cardiac surgery (Senning-Rastelli procedure with placement of an 18-mm Contegra conduit) was performed at the age of 9 months. After the operation, the infant was stable on therapy with diuretics, antiaggregants, beta blockers, and antianemic therapy with vitamin D in prophylaxis. Conclusion – ccTGA with associated anomalies is a rare, life-threatening, congenital heart disease. After birth it demands correct diagnosis, adequate follow-up, and cardiac surgery in infancy.

The purpose of this systematic review is to point out the application of the Fitlight trainer system in sports. The following electronic databases were used to search the literature: Google Scholar, PubMed, Medline, Mendeley, 2014-2020. Following the selection procedure according to the relevant criteria, 22 studies were selected as fit to needs of this systematic review. A review of researches that used the Fitlight training system in sports has revealed a rather heterogeneous selection of topics. The results obtained are classified according to the sports in which the research was conducted. The results summary provided us with the insight into the multiple uses of the Fitlight system in sports as a training and measurement tool. It can be used in both individual and team sports. It can test sensory-cognitive and various motor skills: reaction speed, speed of single movement, speed of running, agility. Based on all of the information provided, the possibility of multiple applications of the Fitlight system in sports was highlighted.
