Polyphenols and Antioxidant Activity of Different Vinegrape Leaves

The volume of the grape waste produced directly relates to the volume of grapes pressed and in turn depends on the specific climatic conditions of the relevant vintage. The aim of this work is to evaluate vinegrape leaves as a potential source of natural antioxidants – polyphenols for their possible use as dietary supplement or food antioxidants. To this purpose antioxidant activity and contents of phenolic compounds of the leaves extracts of five grape varieties of Vitis vinifera L (Vranac, Prokupac, Merlot, Gamay and Italian Rizling), grown in southern Serbia were investigated. The analysis show high content of polyphenols reflecting their high antioxidant activity (R2 = 0.9819, p<0.01). According to the obtained results, the leaves extracts, can be considered rich natural source of phenolic compounds with good antioxidant properties

Automated Fingerprint Identification System: with and without the Possibility of Correction of a Digitalised Image

According to the fact that systems for automatic processing of biometric data are constantly advancing in terms of speed and reliability, as well as in terms of adding new processing capabilities, the question of choosing the appropriate system becomes more important. In this paper the idea is to present the technical and technological solutions of the Automated Fingerprint Identification System with different operating principles, with and without the possibility of correction or coding of a digitized image. Comparisons of different systems were performed in test and production environments. The test database with 10 000 records and about half a million records of dactyloscoped persons in the production of database for testing the performance of search was used. The results have shown that there exists a statistically significant difference (p < 0.001) between examined systems in face fingerprint search according to latent fingerprint databases (which means indirect verification). In the production environment, it was found that there exists statistically significant difference (p < 0.001) in the direct and indirect verification showing advantages and disadvantages of the compared systems

Socioeconomic inequalities in the use of dental health care among the adult population in Serbia

ObjectivesThe aim of this paper is to assess the association of demografic and socioeconomic determinants with utilization of dental services among Serbian adults.Materials and methodsThe study is a part of the population health research of Serbia, conducted in the period from October to December 2019 by the Institute of Statistics of the Republic of Serbia in cooperation with the Institute of Public Health of Serbia “Dr. Milan JovanovićBatut” and the Ministry of Health of the Republic of Serbia. The research was conducted as a descriptive, cross-sectional analytical study on a representative sample of the population of Serbia. For the purposes of this study, data on the adult population aged 20 years and older were used.ResultsMen were approximately 1.8 times more likely than women to not utilize dental healthcare services (OR = 1.81). The likelihood of not utilizing dental healthcare protection rises with increasing age, reaching its peak within the 65–74 age range (OR = 0.441), after which it declines. Individuals who have experienced marital dissolution due to divorce or the death of a spouse exhibit a higher probability of not utilizing health protection (OR = 1.868). As the level of education and wealth diminishes, the probability of abstaining from health protection increases by 5.8 times among respondents with an elementary school education (OR = 5.852) and 1.7 times among the most economically disadvantaged respondents (OR = 1.745). Regarding inactivity, respondents who are not employed have a 2.6-fold higher likelihood of not utilizing oral health care compared to employed respondents (OR = 2.610).ConclusionThe results suggest that individual sociodemographic factors influence utilization of dental services by Serbian adults and confirmed the existence of socioeconomic disparities

Demographic and socioeconomic factors associated with cervical cancer screening among women in Serbia

ObjectivesEffective reduction of cervical cancer incidence and mortality requires strategic measures encompassing the implementation of a cost-effective screening technology. Serbia has made significant strides, introducing organized cervical cancer screening in 2012. However, various impediments to screening implementation persist. The aim of the study was to estimate the socioeconomic factors associated with cervical cancer screening among women in Serbia.MethodsData from 2019 National Health Survey of the population of Serbia were used in this study. The study is cross sectional survey on a representative sample of the population of Serbia. Present total number of participants analyzed in survey 6,747.ResultsIn Serbia, 67.2% of women have done a Pap test at any time during their lives, of which 46.1% of women have undergone cervical cancer screening in the past 3 years. About a quarter of women have never undergone a Pap test in their life (24.3%). The probability of never having a Pap test have: the youngest age group (15–24 years) is 1.3 times more likely than the oldest age group (OR = 1.31), unmarried women 0.3 times more often than married women (OR = 0.37), respondents with basic education 0.9 times more often than married women (OR = 0.98), the women of lower socioeconomic status 0.5 times more often than respondents of high socioeconomic status (OR = 0.56).ConclusionEnhancement of the existing CCS would be the appropriate public health approach to decrease the incidence and mortality of cervical cancer in the Republic of Serbia

PREVENTION OF ADENOVIRAL EYE INFECTION - REVIEW

Epidemic viral conjunctivitis caused by adenovirus is the most common infectious conjunctivitis. The exact incidence of adenoviral conjunctivitis is still poorly known, but there are two well-defined adenoviral keratoconjunctivitis clinical syndromes: epidemic keratoconjunctivitis (EKC) and pharyngoconjunctival fever (PCF). Epidemic keratoconjunctivitis is also the most severe form and presents with watery discharge, hyperemia, chemosis and ipsilateral lymphadenopathy. Diagnosis is mainly clinical, but its etiology can be confirmed using cell cultures, antigen detection, polymerase chain reaction or immune-chromatography. Multiple treatments have been tried for this disease, but none of them seem to be completely effective. Viruses are resistant to desiccation and certain common surface disinfectants. Prevention is the most reliable and recommended strategy to control this epidemic infection. Global epidemic surveillance system definitely needs to be established to monitor and analyze the epidemic conjunctivitis in the future. There is clearly a need for the national and the military public health institutions to work together on guidelines to handle future challenges

Non-invasive treatment of multiple enamel hypoplasia: A case report

Objective. Enamel hypoplasia is a quantitative disorder of enamel deposition during the secretory phase and is characterised by a deficiency of the enamel, while hypomineralization is a qualitative disorder caused by incomplete mineralization and maturation of the enamel, followed by the porosity of the solid dental tissues and the opalescent tooth colour. Clinically, hypoplasia is a risk for caries, tooth sensitivity, erosion, and affects the aesthetic appearance of a patient with a psychological connotation. The aim of the paper is to present the case report, the possibility of preventive measures and restorative treatments with minimally invasive requirements in these patients. Methods. At the Faculty of Medical Sciences, University of Kragujevac, in March 2018, a thirteen-year-old boy was diagnosed with isolated hypoplastic enamel defects on teeth 24, 25, 26, 33 and 34. Results. Enamel hypoplasia was diagnosed by anamnesis, clinical and radiological examination. Preventive measures and conservative interventions were used to prevent progressive abrasion and early tooth loss due to caries and its complications. Conclusion. Early diagnosis, timely preventive methods and minimally invasive restorative treatment can correct anomalies and prevent possible complications.Publishe

Attitudes of Primary School Teachers Toward Inclusive Education

Background: The aims of our study are related to examining the relevance of teachers' attitudes toward the implementation of inclusive education. In addition, its subject is related to the implications on inclusive education policies, limitations of the existing study along with the recommendations for our future research endeavors. Methods: The research is a cross-sectional study type. The sample included 64 primary school teachers in the lower grades of primary school (grades 1–4), selected by using simple random sampling, in three primary schools on the territory of Belgrade, Serbia in 2021 (26, 17, and 21 primary school teachers). The Questionnaire for Teachers, which was used as a research instrument, was taken from the Master's Thesis Studen Rajke, which was part of the project “Education for the Knowledge Society” at the Institute for Educational Research in Belgrade. Dependent variables measured in the study referred to the attitudes of primary school teachers toward inclusive education. Categorical variables are represented as frequencies and the Chi-square test was used to determine if a distribution of observed frequencies differed from the expected frequencies. Results: One in three teachers (32.8%) thought that inclusion was useful for children with disabilities (29.7%), of them thought that schools did not have the conditions for inclusive education, whereas one in four teachers (25.0%) believed that inclusion was not good. No statistically significant differences were found in the attitudes of professors, when observed in terms of their gender, age and length of service. Conclusion: Investing more resources and time in developing and implementing special education policies can promote successful inclusive education

Mental Health Assessment of Cancer Patients: Prevalence and Predictive Factors of Depression and Anxiety

Background: Patients with oncological diseases often have mental disorders in the form of comorbidity. The aim of this study was to research the association of cancer with the presence of symptoms of depression and anxiety in primary health care patients.Methods: This prospective observational study done in 2020 included adult users of health care at the Health Center Trstenik, Central Serbia, aged 19 and over, both sexes, with a diagnosis of oncological disease. A research instrument to assess depressive symptoms is used PHQ-9 (The Patient Health Questionnaire) questionnaire, derived from PRIME MD- and (The Primary Care Evaluation of Mental Disorders), and the Beck Anxiety Scale (BAI) to register the presence of certain anxiety symptoms.Results: The largest percentage of patients had symptoms of mild (27.2%) or moderate depression (22%), while 18% reported symptoms of major depression. The level of depression was higher in older subjects, in the presence of chronic diseases with greater limitations of activity and the presence of difficulties in performing daily activities, with a more pronounced effect of pain on activity, the presence of stress. All subjects were characterized as persons with severe anxiety (score 26-63). The level of anxiety was higher in older respondents, in the presence of long-term illness, with greater limitations of activities and difficulties in performing daily activities, with a more pronounced influence of pain on performing activities and the influence of the media.Conclusion: Caring for the mental health of cancer patients must occupy a significant part of each country's national health policy
