tick borne encephalitis in serbia a case series

Introduction: In the Europe, the number of tick-borne encephalitis (TBE) has been increased in the last decade, and the number of endemic areas has been also increased and is still growing. In the present case series, we present clinical and socio-epidemiological data of patients with TBE hospitalized in the period of TBE virus epidemic in Serbia. Methodology: A case series was conducted in Serbia in 2017. Patients with confirmed TBE were included in the study. Biochemical and serological analysis of blood and CSF, as well as radiological imaging (CT and MRI) were done. Results: In total, 10 patients with TBE were included in the study. M:F ratio was 1.5:1, while average age was 45.1 years. Half of the patients had severe clinical picture. Endocranial CT scan and MRI did not reveal any abnormality, except in the patient with the most severe CNS infection (meningoencephalomyelitis). Mean value of sedimentation and CRP was slightly elevated (29.6 mm/1hours and 20.1 mg/L, respectively) in 80% of the patients, although elevation was almost negligible. The average number of leucocytes in the cerebrospinal fluid (CSF) was 171×106/L, the mean value of the CSF protein was 1.1g/L. There were no fatal outcomes. Conclusion: Since other CNS infections have similar clinical picture and CSF finding as TBE, serological analysis for TBE should be included in routine diagnostic practice

The Impact of Hippocampal Sex Hormones Receptors in Modulation of Depressive-Like Behavior Following Chronic Anabolic Androgenic Steroids and Exercise Protocols in Rats

The aim of this study was to evaluate alterations in depressive-like behaviors in rats following chronic administration of a supraphysiological dose of anabolic androgenic steroids (AASs) as well as exposure to a prolonged exercise protocol. The role of hippocampal sex hormones receptors in the modulation of depressive-like behavior was also assessed. A total of 48 male Wistar albino rats were divided into six groups: control, exercise (1 h/day, five consecutive days), nandrolone-decanoate (ND, 20 mg/kg/week, in a single dose), exercise plus ND, testosterone-enanthate (TE, 20 mg/kg/week, in a single dose), and exercise plus TE. After the 6-week protocols were complete, the rats underwent behavioral testing in the tail suspension test (TST). Rats were sacrificed for the collection of blood samples, to determine sex hormones levels, and isolation of the hippocampus, to determine [androgen receptors (AR) and estrogen receptors α (ERα)] expression. ND and TE treatment induced significant depressive-like behavior, opposing the antidepressant effect of exercise. Chronic TE administration elevated testosterone (T) and dihydrotestosterone (DHT) serum levels, and this was augmented by exercise. In contrast, ND and exercise alone did not alter T or DHT levels. There were no changes in serum estradiol levels in any of the groups. Immunohistochemical analysis showed that exercise reduced AR immunoreactivity in all hippocampal regions and increased the ERα expression in the CA1, dentate gyrus (DG), and total hippocampal sections, but not in the CA2/3 region. AASs administration increased AR expression in all hippocampal regions, although not the total hippocampal section in the TE group and did not significantly decrease ERα. The hippocampal AR/ERα expression index was lowered while parvalbumin (PV)-immunoreactivity was enhanced by exercise. AASs administration increased the AR/ERα index and reduced PV-immunoreactivity in the hippocampus. The number of PV-immunoreactive neurons negatively correlated with the antidepressant effects and the AR/ERα ratio. Our results suggest a potential role of the numerical relationship between two sex hormones receptors (stronger correlation than for each individual receptor) in the regulation of depressive-like behavior via the hippocampal GABAergic system in rats, which allow better understanding of the hippocampal sex hormones receptors role in modulation of depressive-like behavior

Serological status of childbearing-aged women for Toxoplasma gondii and cytomegalovirus in northern Kosovo and Metohija

Abstract INTRODUCTION: Toxoplasma gondii and cytomegalovirus (CMV) are pathogens associated with congenital anomalies. METHODS: Serum was collected from 79 reproductive-age women and tested for IgM and IgG antibodies to T. gondii and CMV. RESULTS: Seropositivity for T. gondii was detected in 24.1% of women and CMV in 96.2%. High seropositivity for CMV was found for all ages. The highest seropositivity for T. gondii was observed among older participants. CONCLUSIONS: T. gondii remains an important pathogen owing to low seropositivity

Risk Perception About HIV Among University Students in One of the Last Hotspots for HIV Transmission in Europe

Abstract Background HIV testing in the Northern Kosovo province is challenging, because the infrastructure is being rebuilt after the ethnic conflict. The purpose of this research was to examine self-perceived risk for acquiring HIV infection and factors associated with risk assessment among university students. Methods Students completed a questionnaire on socio-demographic data, knowledge about HIV prevention and transmission, attitudes toward people living with (PLHIV) and self-perceived risk for HIV infection. The self-perceived risk was categorized as low, unknown and high. Results The majority of students (72.5%) assessed their risk as low, 8.5% assessed their risk as high and 19.1% did not know their risk. Compared to low self-perceived risk, high self-perceived HIV risk was associated with being male, having lower knowledge about HIV prevention, less strong Segregation and protection attitude toward PLHIV, stronger Ignorance and indifference attitude toward PLHIV and positive opinion about gays/lesbians. Students who perceived own risk for acquiring HIV as high had lower knowledge about HIV transmission and prevention. However, those who were previously tested for HIV, despite their poorer knowledge about HIV prevention, assess their HIV-related risk as low. Conclusions Students assessed their risk of HIV infection mostly as low. Still, lower knowledge of HIV prevention has been consistently associated with a high and unknown risk of HIV. Moreover, being ignorant and indifferent about PLHIV was associated with increased self-perceived HIV risk. These findings highlight the need for continuous specialized HIV-related education to reduce fear and stigma of PLHIV and HIV testing as well as risky behaviors
