Summary

School curriculum and syllabus of physical education sets in front of the pupils the objectives and tasks that could be, by their nature, both physical and socio-psychological while the level of mastering of the contents is measured with a mark that is seen as the result of efficiency of overall educational process at a certain education level. However, the mark in physical education is a composite of numerous factors, one of which is motivation that can be considered within a school environment as readiness for an active engagement of pupils during classes (contrary to passive and mechanical fulfilment of requirements and acting based on the teachers’ demand, or open and direct obstruction of a class, disturbing of discipline and refusal to actively implement the curriculum). Therefore, it is important to take pupils’ motivation into account in order to fulfilthe sense of physical education classes, remedy the potential shortcomings, and improve additionally the planned syllabus. The Scale for measurement of readiness for active involvement at physical education classes in elementary school has been designed with that aim since early adolescence is considered a critical period for adopting of healthy lifestyles and its metric characteristics have also been tested. The Scale consists of five levels, of Likert’s type and it consists of two sub-scales (Commitment and Winning) with nine statements in total.

With good psychometric characteristics, easy understanding, concise contents and short and simple setting it is recommended for further work and additional research in the field of motivation in physical education in both elementary and secondary school.

Abstract

During 2015/2016, fecal and intestinal samples from live diseased and/or dead pigs with suspected PEDV and/or TGEV and signs of rotavirus infection were collected from in total seven different farrow-to-finish swine farms located in Northern Serbia region (Vojvodina Province). A total of 14 samples (2 pools per farm) of small intestine with fecal content were submitted to laboratory molecular investigation (multiplex RTPCR). On these farms the clinical signs included the occurrence of diarrhea in suckling and weaned piglets, with weak or no response to the applied antimicrobial therapy. The epidemic of severe diarrhea affecting pigs of all ages on one farrow-to finish swine farm was detected in January 2016. Watery diarrhea in all swine categories was associated with vomiting and a reduction in feed consumption. Diarrheic, gaunt and dehydrated piglets, covered with feces were found in 90% litters. The disease affected most severely the suckling piglets, and the mortality in newborn piglets was up to 35%. In the weaned piglets and fatteners the mortality was up to 2.5% and 1.2%, respectively. The PEDV RNA was detected in pooled feces and samples of small intestines derived from diseased and dead suckling piglets from only one investigated farm. The PEDV positive samples showed to be negative for rotavirus group A and TGEV. The transport vehicles were identified as the main possible route of PEDV introduction. This is the first report demonstrating the presence of PEDV in Serbia.

Summary

Background/Aim: The aim of the present study was to investigate the treatment options, survival rate of traumatized primary teeth and evaluate the factors influencing the outcome. Material and Methods: The sample consisted of all dental trauma cases treated over a 14 years period at the Department of Pediatric and Preventive Dentistry, Dental Clinic of Vojvodina, Novi Sad. Criteria for inclusion in this study were: dental trauma to primary teeth and age in the moment of injury up to seven years. Dental trauma records were analyzed in order to obtain the following: gender and age of the child at the time of trauma, type of trauma, as well as the type and timing of treatment received. After data analysis a survival rate of traumatized primary teeth was evaluated. Results: The study was designed as retrospective and it included 225 children, with 346 traumatized primary teeth. The occurrence of trauma was higher in male patients (60,4%) and in children up to 4 years of age. Luxations were more frequent (72.8%) compared to isolated teeth fractures (20.8%), while the two types of injury combined were rare (6,3%). One year following dental trauma 231 teeth (0.67%) developed complications. Falls were the main cause of trauma (68.9%) and the presence of more than one traumatized tooth was frequent. A percentage of 48.8 children received dental care during first 24 h after the injury. Conclusions: Survival of injured primary teeth is relatively low, regardless of trauma type, time interval between injury and treatment and the type of provided treatment.

Abstract

Diatom samples were collected during July 2010 at 15 localities from different types of substrate (stone surfaces, sand, mud, filamentous algae and submerged mosses) from the Dojkinci River. During the research period, 124 taxa were determined within 43 genera. Among numerous common diatoms we recorded three taxa for the first time in Serbia: Brachysira intermedia (Øst.) Lange-Bertalot, Chamaepinnularia mediocris (Krass.) Lange-Bertalot and Navicula tridentula Krass. Also, we observed 21 taxa which are rarely recorded taxa for Serbia. The most interesting was Diatomella balfouriana Grevill. that was previously known only from the River Tisa near Titel. In the studied material, it was identified only in samples collected from the surface of boulders with mosses at the third locality. Their morphology, distribution and ecology are presented in this paper.

ABSTRACT

Hepatorenal syndrome (HRS) involves reversible renal failure in patients with advanced cirrhosis or acute liver failure. The aim of the study was to determine the pathogenetic mechanisms of the development of hepatorenal syndrome and to emphasise the clinical importance of early detection and timely treatment of patients with this condition. Th e one-year incidence rate of hepatorenal syndrome in patients with liver cirrhosis is 18-20%. Th e risk factors for the development of hepatorenal syndrome include the following: spontaneous bacterial peritonitis, gastrointestinal bleeding, nephrotoxic drugs, diuretics, non-steroidal anti-inflammatory drugs, and hyponatraemia. The primary plan of treatment is a liver transplantation, while a secondary plan of treatment is the use of a vasoconstrictor in conjunction with albumin. Early diagnosis and prompt appropriate treatment can significantly reduce the mortality rate of patients with hepatorenal syndrome.

Abstract

How consumers will behave when buying wine depends on many factors, among which economic, social, demographic, psychological and situational ones are highlighted. Research in wine consumer attitudes in Serbia is aimed at creating appropriate marketing strategies. This paper analyses the influences of demographic factors on wine consumption.Special attention was paid to the impact of the wine characteristics that affect the decision to buy the local or imported wines with geographical origin. It should be added that wine tourism is particularly important in increasing the sales of wine by direct and indirect means.To this aim, 1.705 wine buyers and consumers were interviewed during 2015. Based on Chi-test, it has been proven that the age group affects the decision on the purchase of wine. Understanding consumer motivation is possible through an adequate marketing approach which will provide increased sales of domestic wine and the quicker development of the national market.

Abstract

Background: Toxic hepatitis may clinically manifest as other diseases of the liver, where it must always be considered in differential diagnoses of unexplained liver damage, such as poisoning with kombucha tea.

Case report: 47-year old female patient was hospitalized and has consumed daily ounces of kombucha tea. During hospitalization patient was diagnosed with toxic hepatitis and treated with intravenous solutions of hepatic protective and ursodeoxycholic-acid (effective therapy).

Conclusion: Examinations showed that kombucha tea has potential to revert the CCl4-induced hepatic toxicity, but used in overdose can induce toxicity himself.

Abstract

Breast metastases from an extra-mammary malignancy are rare. Among the lung malignancies that metastasise in the breasts, previous literature has described approximately 30 cases of NSCLC and only a few cases of SCLC. Here, we present a 54-year-old woman with metachronous breast metastasis from pulmonary small cell carcinoma. She presented with a soft tissue mass in the right lung hilum. After bronchoscopy with biopsy, SCLC was verified. Th e patient was given 4 cycles of etoposide and cisplatin followed by radiation therapy. Seven months after the diagnosis of primary lung cancer, the patient palpated a mass in her right breast. Clinical examination and further diagnostics revealed the suspected malignancy, and a radical mastectomy was performed. Immunohistochemical findings suggested metastatic SCLC in the breast. Differentiation between primary and metastatic cancer in the breast is very important for therapeutic planning

Summary

The first line of defence in parasitic infection is the innate immune system. On the other hand, adaptive immune system posseses numerous mechanisams of hummoral and cellular immunity.

Cellular immunity in a helminth infection is characterised by Th2 immune response. Considering the fact that the aim of a parasite is not to kill its host, the majority of parasites are highly addapted to the life inside the host, and succesefully avoid or limit its deffences. A special signifficance of the parasite as a potential pathogen is its possibility to escape immunity. Numerous helminths are releasing different substances that are acting as lymphocyte suppressors and macrophage inactivators and they are capable of destroying antibodies. They have a possibility of camouflage, sequestration and surface shell peeling with the aim to avoid immune response. Latest research in the field of immunology has revealed the significance of CD40 co-stimumlating protein of antigen presenting cells in the immune response to parasitic infection.

Immune response in the course of parasitic infestion is important in pathogenesis of helminthioses.

Summary

Background: Oxidized low density lipoprotein (ox-LDL) and high-sensitive C-reactive protein (hs-CRP) are elevated in diabetes mellitus (DM) and associated with accelerated atherosclerosis. Little is known about their dynamics in the acute phase of ST segment elevation myocardial infarction (STEMI), especially in relation to the presence of DM and pre-diabetes (pre-DM). This study aimed to analyze timedependent changes in ox-LDL and hs-CRP regarding the presence of pre-DM and DM in STEMI patients treated by primary percutaneous coronary intervention (pPCI).

Methods: In 103 consecutive patients with the first anterior STEMI ox-LDL and hs-CRP were measured before pPCI, on day 2 and day 7 after pPCI.

Results: Patients were classified into: non-diabetics, pre-diabetics and diabetics. In each group the maximal ox-LDL concentration was found on admission, decreased on day 2 and reached the lowest values on day 7 (p<0.001). Diabetics had the highest ox-LDL concentrations compared to pre-diabetics and non-diabetics (on admission: p=0.028, on day 2: p=0.056, on day 7: p=0.004). hs-CRP concentration rose from admission, reached its peak on day 2 and decreased on day 7, in each group (p<0.001). Significant differences in hs-CRP concentrations were found between non-diabetics and pre-diabetics on admission (p=0.018) and day 2 (p=0.026). In a multivariate analysis DM was an independent determinant of high ox-LDL concentrations. Both ox-LDL and hs-CRP significantly correlated with Killip class, left ventricular ejection fraction, NT-proBNP and peak troponin I.

Conclusions: In patients with the first STEMI treated by pPCI there were significant differences in ox-LDL and hs-CRP concentrations between non-diabetics, pre-diabetics and diabetics. Ox-LDL and hs-CRP concentrations were related to heart failure parameters.
