Sagittal Abdominal Diameter as the Best Predictor of Metabolic Syndrome in HIV-Infected Men on Antiretroviral Therapy.

BACKGROUND: The interaction of human immunodeficiency virus (HIV), host and antiretroviral therapy causes a range of metabolic disorders that can be characterized as a metabolic syndrome (MetS) that increases the cardiovascular risk. MetS involves central obesity, which can be detected using different anthropometric parameters. OBJECTIVE: To assess the abilities of different anthropometric parameters in the prediction of MetS in HIV-infected men on ART. METHOD: The study involved 92 male participants (mean age 44.46±10.38 years), divided into two groups: with and without MetS. All subjects underwent biochemical evaluation (triglycerides, HDL-cholesterol, fasting glucose), blood pressure measurement and anthropometric assessment: body mass, body height, body mass index (BMI), body fat mass, body circumferences (chest, upper arm, forearm, waist, hip, proximal and middle thigh and calf), sagittal abdominal diameter (SAD), skinfold thicknesses (subscapular, anterior and posterior upper arm, anterior and lateral forearm, abdominal, supraspinal, thigh and calf), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist-to-thigh ratio (WTR), sagittal abdominal diameter-to-body height ratio (SADH), body adiposity index (BAI) and conicity index. MetS was specified according to IDF criteria. RESULTS: Subjects with MetS had statistically significant higher values of all anthropometric parameters except middle thigh circumference, calf skinfold and body height. According to ROC analysis and Binary Logistic Regression, SAD has been shown as the best predictor of MetS with a predictive value of 21.40 cm (AUC:0.91), followed by WHR with a predictive value of 0.93. CONCLUSION: Sagittal abdominal diameter is the strongest anthropometric indicator of MetS in HIV-infected patients on ART.

Diagnostic value of urine qRT-PCR for the diagnosis of West Nile virus neuroinvasive disease.

Short and low-level viremia and virorachia, antibody cross-reactivity, IgM persistence, and inaccessibility of neutralization test, make laboratory diagnosis of West Nile virus (WNV) infection difficult. Recent investigations imply that WNV is excreted in urine longer and at higher concentrations compared to blood. The detection of WNV nucleic acid in cerebrospinal fluid (CSF), serum, and urine samples collected from 41 patients with suspected WNV neuroinvasive disease, was done by real-time RT-PCR assay. CSF and serum samples were also serologically tested using anti-WNV IgM/IgG ELISA kits. WNV infection was confirmed in 46.3% of patients by positive WNV RNA results in serum and/or CSF samples. The WNV RNA testing of urine allowed confirmation of 31.7% more cases. No association between WNV RNA urine positivity and age, gender, or the day of sample collection was found. The urine qRT-PCR can be a valuable diagnostic test for confirmation of probable cases of WNV neuroinvasive disease.

COVID-19 Breakthrough Infections among Patients Aged ≥65 Years in Serbia: Morbidity and Mortality Overview.

BACKGROUND: Vaccines against severe acute respiratory syndrome coronavirus 2 have shown effectiveness in the prevention of COVID-19. Breakthrough infections occur, and age has been shown to be one of the dominant risk factors for poorer outcome. This research focuses on characteristics of breakthrough infections in older adults. METHODS: This retrospective study was conducted for four months (March−June 2021) in the autonomous province of Vojvodina in Serbia on 11,372 patients using reverse-transcription polymerase chain reaction or antigen-detection rapid diagnostic tests verifying COVID-19 in those aged ≥65 years. Demographics, comorbidities, disease severity, and final outcomes were evaluated in fully vaccinated compared to unvaccinated individuals. Individuals were divided into younger-old (65−74 years) and older-old (≥75 years) age groups and differences between those groups were further evaluated. Binary logistic regression was performed to identify independent predictors of poor outcome. RESULTS: By the end of the research, 51.3% of the population of APV 65−74 years, as well as 46.2% of those older than 74 years, were vaccinated. From the acquired sample, 17.4% had breakthrough infection. Asymptomatic forms were higher in both age groups of vaccinated vs. unvaccinated (3.9%­younger-old, 6.3%­older-old vs. 2.9%­younger-old, 3.9%­older-old). The same results were registered with mild symptoms (82.1%­younger-old, 68.1%­older-old vs. 76.3%­younger-old, 57.5%­older-old) (p < 0.001). The case fatality ratio of the vaccinated population was smaller than the unvaccinated population in both groups (3.1% vs. 7.9%­younger-old; 11.4% vs. 22.5%­older-old) (p < 0.001). The odds ratio for poor outcome in unvaccinated individuals was 2.3 (95% confidence interval, p < 0.001) for the total sample. CONCLUSIONS: An increase in asymptomatic and mild forms, as well as decrease in severe or critical forms and poor outcomes, were noted in the vaccinated population. Choosing to avoid vaccination against SARS-CoV-2 may increase the chance of poor outcome in older individuals.

Unexpected TBEV Seropositivity in Serbian Patients Who Recovered from Viral Meningitis and Encephalitis.

The tick-borne encephalitis virus (TBEV) causes a life-threatening disease named Tick-borne encephalitis (TBE). The clinical symptoms associated with TBE range from non-specific to severe inflammation of the central nervous system and are very similar to the clinical presentation of other viral meningitis/encephalitis. In consequence, TBE is often misclassified by clinical physicians, mainly in the non-identified high-risk areas where none or only a few TBE cases have been reported. Considering this situation, we hypothesized that among persons from northern Serbia who recovered from viral meningitis or encephalitis, there would be evidence of TBEV infection. To test this hypothesis, in this observational study, we evaluated the seroreactivity against TBEV antigens in patients from northern Serbia who were hospitalized due to viral meningitis and/or viral encephalitis of unknown etiology. Three cases of seroreactivity to TBEV antigens were discovered among convalescent patients who recovered from viral meningitis and/or encephalitis and accepted to participate in the study (n = 15). The clinical and laboratory findings of these patients overlap with that of seronegative convalescent patients. Although TBE has been a notifiable disease in Serbia since 2004, there is no active TBE surveillance program for the serologic or molecular screening of TBEV infection in humans in the country. This study highlights the necessity to increase the awareness of TBE among physicians and perform active and systematic screening of TBEV antibodies among patients with viral meningitis and/or encephalitis.

Tick-Borne Encephalitis Virus Seropositivity among Tick Infested Individuals in Serbia.

Tick-borne encephalitis (TBE), caused by the TBE virus (TBEV), is a life-threatening disease with clinical symptoms ranging from non-specific to severe inflammation of the central nervous system. Despite TBE is a notifiable disease in Serbia since 2004, there is no active TBE surveillance program for the serologic or molecular screening of TBEV infection in humans in the country. This prospective cohort study aimed to assess the TBEV exposure among tick-infested individuals in Serbia during the year 2020. A total of 113 individuals exposed to tick bites were recruited for the study and screened for anti-TBEV antibodies using a commercial indirect fluorescent antibody test (IFA) test. Blood samples from 50 healthy donors not exposed to tick bites were included as a control group. Most of the enrolled patients reported infestations with one tick, being I. ricinus the most frequent tick found in the participants. The TBEV seroprevalence was higher (13.27%, 15 total 113) in tick-infested individuals than in healthy donors (4%, 2 total 50), although the difference was not significant. Notably, male individuals exposed to tick bites showed five times higher relative risk (RR) of being TBEV-seropositive than healthy donors of the same gender (RR= 5.1, CI = 1.6-19; p = 0.007). None of the seropositive individuals developed clinical manifestations of TBE, but the first clinical-stage of Lyme borreliosis (i.e., erythema migrans) was detected in seven of them. Potential TBEV foci were identified in rural areas, mostly in proximity or within the Fruska Gora mountain. We conclude that the Serbian population is at high risk of TBEV exposure. Further epidemiological studies should focus on potential TBEV foci identified in this study. The implementation of active surveillance for TBEV might contribute to evaluating the potential negative impact of TBE in Serbia.

Validation of the STANDARD Q COVID-19 antigen test in Vojvodina, Serbia.

BACKGROUND: Since COVID-19 pandemic is a global crisis, tests with high sensitivity and specificity are crucial for the identification and management of COVID-19 patients. There is an urgent need for low-cost rapid antigen COVID-19 test with a good diagnostic performance. Although various antigen rapid detection tests are widely available, strong evidence of their usefulness in clinical practice are still limited. Therefore, our aim was to evaluate clinical performance of STANDARD Q COVID-19 Ag Test (SD Biosensor, Gyeonggi-do, South Korea). METHODS: The performance of the STANDARD Q COVID-19 Ag Test for the detection of SARS-CoV-2 antigen was evaluated in comparison to RT-qPCR results in 120 symptomatic patients (median age 49, IQR 36-70) who presented to health care facility in Novi Sad, Vojvodina, Serbia. RESULTS: Twenty five out of 120 samples have been tested positive using STANDARD Q COVID-19 Ag Test, and all of them were also positive on RT-qPCR. Overall, the STANDARD Q COVID-19 Ag Test showed sensitivity of 58.1% (95% CI 42.1-73.0) but it was higher in the early days of disease, when the highest viral loads were detected. During the first five days after the symptom onset, the sensitivity ranged from 66.7% to 100% and the pooled accuracy and Kappa values were high (0.92 and 0.852). CONCLUSIONS: A strong agreement between performance of STANDARD Q COVID-19 Ag Test and RT-qPCR was observed during the first five days of illness, suggesting that this rapid antigenic test can be very useful for COVID-19 diagnosis in the early phase of disease.

Associations of visceral fat thickness and anthropometric measurements with non-alcoholic fatty liver disease development in male patients mono-infected with human immunodeficiency virus.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) represents the most common form of chronic liver disease in mono-infected (without concomitant hepatitis B and/or C virus infection) people living with human immunodeficiency virus (HIV). The proper and on time identification of at-risk HIV-positive individuals would be relevant in order to reduce the rate of progression from NAFLD into non-alcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma. OBJECTIVES: The aim of this study was to explore visceral fat thickness (VFT) and anthropometric measurements associated with the development of NAFLD in patients mono-infected with HIV and on long-standing combination antiretroviral therapy (cART). METHOD: Eighty-eight (n = 88) HIV-positive male patients, average age 39.94 ± 9.91 years, and stable on cART, were included in this prospective study. VFT was measured using ultrasonography. Anthropometric measurements included body mass index (BMI), waist-to-hip ratio (W/H), waist-to-height ratio (WHtR), waist and hip circumference (WC, HC). Differences between variables were determined using the chi-square test. The receiver operating characteristic (ROC) curve and the Youden index were used to determine optimal cut-off values of VFT and hepatic steatosis. The area under the curve (AUC), 95% confidence intervals, sensitivity and specificity are reported for the complete sample. Significance was set at p < 0.05. RESULTS: Patients with steatosis had significantly higher values of BMI, HC, WC, W/H and WHtR. The VFT was higher in patients with steatosis (p < 0.001). Specifically, VFT values above 31.98 mm and age > 38.5 years correlated with steatosis in HIV-positive patients, namely sensitivity 89%, specificity 72%, AUC 0.84 (95% CI, 0.76-0.93, p < 0.001), with the highest Youden index = 0.61. The sensitivity of the age determinant above this cut-off point was 84%, specificity 73% and AUC 0.83 (95% CI, 0.75-0.92, p < 0.001), with the highest Youden index of 0.57. CONCLUSION: In the absence of more advanced radiographic and histological tools, simple anthropometric measurements and VFT could assist in the early identification of persons at risk of hepatic steatosis in low- and middle-income regions.

Incidence, severity and risk factors of peripheral intravenous cannula-induced complications: An observational prospective study.

AIMS AND OBJECTIVES: To determine the incidence, severity and risk factors of peripheral intravenous cannula-induced complications. BACKGROUND: Peripheral venous cannulation in hospitalised patients may cause complications such as phlebitis, infiltration, occlusion and dislodgement. A review of the literature reveals the discrepancy in their incidence and identification of a wide range of risk factors, whereas the data on the occurrence and degree of severity are insufficient. DESIGN: An observational prospective study. METHODS: The study observed 1,428 peripheral intravenous cannula insertion among 368 adult patients hospitalised at the tertiary healthcare clinics. The data collection and analysis included patients' medical data and the data related to each cannula (including placement, monitoring and the reasons for removal), as well as the data on the type of administered medications and solutions. Reporting of this research adheres to the STROBE guidelines. RESULTS: Phlebitis ranked first among complications with occurrence of 44%, followed by infiltration of 16.3%, while the incidence of occlusion and catheter dislodgement was 7.6% and 5.6%, respectively. In assessing the occurrence of phlebitis, multivariate analysis highlighted the presence of comorbidity, current infection, catheter size, time in situ and the number of administrations of infusion solutions associated with risk, whereas 20-gauge catheter, two or more attempts at cannulation and administration of a high-risk solutions during the first day have been singled out with regard to infiltration. As for the severity, the most common was medium stage of phlebitis, whereas grade 2 was most commonly observed for infiltration. CONCLUSION: The incidence of infiltration, occlusion and dislodgment is almost congruent with the average incidence of previous studies. However, the incidence and degree of severity associated with the occurrence of phlebitis were significantly higher. RELEVANCE TO CLINICAL PRACTICE: The results of the study draw attention to vulnerable groups of patients, cannula-specific and pharmacological risk factors for the development of peripheral intravenous cannula-induced complications.

Molecular Detection and Serological Evidence of Tick-Borne Encephalitis Virus in Serbia.

Tick-borne encephalitis (TBE) is a zoonotic flaviviral infection that is a growing public health concern in European countries. The aims of this research were to detect and characterize tick-borne encephalitis virus (TBEV) in Ixodes ricinus ticks at presumed natural foci in Serbia, and to determine seroprevalence of TBEV IgG antibodies in humans and animals. A total of 500 I. ricinus ticks were examined for the presence of TBEV by real-time RT-PCR, and conventional nested PCR and sequencing. To determine TBEV seroprevalence, 267 human sera samples were collected, as were 200 sera samples from different animal species. All sera samples were examined by ELISA for the presence of anti-TBEV antibodies. To exclude cross-reactivity, all sera samples were tested for anti-West Nile virus (WNV) antibodies and all human sera samples were also tested for anti-Usutu virus antibodies by ELISA. Results of this preliminary study indicated TBEV activity in Serbia at two microfoci. Several decades after the previous documentation of TBEV in Serbia, we have demonstrated the presence of TBEV in I. ricinus questing nymphs (prevalence 2% and 6.6% at the two different localities) and anti-TBEV antibodies in humans (seroprevalence 0.37%). Moreover, we show for the first time TBEV seroprevalence in several animal species in Serbia, including dogs (seroprevalence 17.5%), horses (5%), wild boars (12.5%), cattle (2.5%), and roe deer (2.5%). None of the goats tested was positive for anti-TBEV IgG antibodies. TBEV isolate from I. ricinus tick in this study belonged to the Western European subtype. To understand the true public health concern in Serbia, detailed epidemiological, clinical, virological, and acarological research are required. This is important for implementation of effective control measures to reduce the incidence of TBE in Serbia.

A prominent lactate peak as a potential key magnetic resonance spectroscopy (MRS) feature of progressive multifocal leukoencephalopathy (PML): Spectrum pattern observed in three patients.

Progressive multifocal leukoencephalopathy (PML) is a rare, often fatal, opportunistic infection, associated with demyelinating process. PML is caused by John Cunningham (JC) polyomavirus, and predominantly affects patients with human immunodeficiency virus (HIV) infection or other immunocompromised patients. The purpose of this study was to determine the role of magnetic resonance spectroscopy (MRS) in establishing the diagnosis of PML. MRS with long and short echo time was performed in two patients with PML associated with HIV infection and in one PML patient associated with chronic lymphocytic leukemia. The most prominent peak on the obtained spectra was for lactate; it showed 2-3 times higher concentration of lactate compared to choline, almost 4-6 times higher lactate concentration compared to creatine, and 4-11 times higher lactate in comparison to N-acetylaspartate concentration. Similar spectrum pattern was observed in all patients. To the best of our knowledge, this is a new finding that might be useful in early diagnosis of PML. Nevertheless, further confirmation of our results is needed, since we analyzed the spectrum pattern only in three patients. Overall, our results could help in early detection of PML, especially in non-HIV patients, and thus prevent the fatal outcome of the disease. MRS could also be useful in detecting "tumefactive" demyelinating lesions in PML patients, associated with immune reconstitution inflammatory syndrome, to avoid misdiagnosis of neoplasm.

HIV-associated neurodegeneration and neuroimmunity: multivoxel MR spectroscopy study in drug-naïve and treated patients.

OBJECTIVES: The aim of this study was to test neurobiochemical changes in normal appearing brain tissue in HIV+ patients receiving and not receiving combined antiretroviral therapy (cART) and healthy controls, using multivoxel MR spectroscopy (mvMRS). METHODS: We performed long- and short-echo 3D mvMRS in 110 neuroasymptomatic subjects (32 HIV+ subjects on cART, 28 HIV+ therapy-naïve subjects and 50 healthy controls) on a 3T MR scanner, targeting frontal and parietal supracallosal subcortical and deep white matter and cingulate gyrus (NAA/Cr, Cho/Cr and mI/Cr ratios were analysed). The statistical value was set at p < 0.05. RESULTS: Considering differences between HIV-infected and healthy subjects, there was a significant decrease in the NAA/Cr ratio in HIV+ subjects in all observed locations, an increase in mI/Cr levels in the anterior cingulate gyrus (ACG), and no significant differences in Cho/Cr ratios, except in ACG, where the increase showed trending towards significance in HIV+ patients. There were no significant differences between HIV+ patients on and without cART in all three ratios. CONCLUSION: Neuronal loss and dysfunction affects the whole brain volume in HIV-infected patients. Unfortunately, cART appears to be ineffective in halting accelerated neurodegenerative process induced by HIV but is partially effective in preventing glial proliferation. KEY POINTS: • This is the first multivoxel human brain 3T MRS study in HIV. • All observed areas of the brain are affected by neurodegenerative process. • Cingulate gyrus and subcortical white matter are most vulnerable to HIV-induced neurodegeneration. • cART is effective in control of inflammation but ineffective in preventing neurodegeneration.

May Patients with Alcohol Liver Disease Benefit from Herbal Medicines?

Alcoholism is currently listed as the third leading cause of death. Chronic alcohol consumption brings serious medical complications like gastrointestinal, cardiovascular, musculoskeletal, respiratory system disorders. Liver can be seriously damage by alcohol misuse. Alcoholic Liver Disease (ALD) is the first important warning sign of alcohol abuse. Since effective therapies for ALD are still limited, natural products in the treatment of ALD become very important. In this regard, there have been done very few clinical trials with poor results. Silymarin, glycyrrhizin, garlic show some promising results in ALD patients while the in vivo and in vitro studies with green tee, quercetin and curcumin indicate positive effect on patients with ALD.

Prevention program for Clostridium difficile infection: a single-centre Serbian experience.

BACKGROUND: Clostridium difficile (C. difficile) diarrhea is a common, iatrogenic, nosocomial disease with a worldwide diffusion. Recent studies reported that the incidence of C. difficile infection (CDI) is rising, due to aging of the population and to greater prevalence of hypervirulent strains. We investigated whether the application of a prevention program lead to a decline in the incidence of intrahospital CDI. METHODS: The study was designed as observational, to compare the efficacy of Schülke preventive program with the standard protocols, in a period of 4 months. For every patient with community-onset healthcare facility-associated (HCFA) CDI, we randomly selected four controls (1:4) with the same ICD code but without HCFA CDI. For statistical analysis the nonparametric, one-way ANOVA, univariate regression analysis, univariate analysis of variance, and Welch and Brown-Forsythe Test were used. RESULTS: Clinical features of HCFA CDI were typical. HCFA CDI group was significantly older than control group (P=0.008 and F=6.686; Partial Eta Square=0.013). Patients with HCFA CDI stayed significantly longer in hospital (P=0.000 and F=69.379; Partial Eta Square=0.117). Acquiring CDI prolonged the hospitalization of 14.52 days. HCFA CDI significantly increases the total cost of hospitalization as well as each element of the price respectively. With the application of the prevention program the annual incidence of CDI dropped from 49.01 in 2013 to 18.22/10000 bed days in 2014. CONCLUSIONS: Applying Schülke preventive program, implemented in 2014, has led to significant savings for the hospital compared to previous methods.

Non-cirrhotic Portal Hypertension Associated with Didanosine and Streptococcus agalactiae Infection: A Case Report.

BACKGROUND: Non-Cirrhotic Portal Hypertension (NCPH) is a rare but potentially fatal liver disorder described in patients treated with anti-retroviral therapy for Human Immunodeficiency Virus (HIV). In particular, the most important predisposing factor to its development has been identified as prolonged exposure to Didanosine (ddI). The clinical entity of NCPH is characterized by an increase in portal pressure due to pre- or intra-hepatic causes, in absence of liver cirrhosis. However, the exact pathogenesis remains poorly understood, and due to its rarity, the diagnosis is often delayed. OBJECTIVE: We herein report a case in which ddI administration, with concomitant spontaneous bacterial peritonitis by Streptococcus agalactiae, has induced NCPH in a HIV male patient. CONCLUSION: NPCH should be suspected when HIV patient with an history of ddI treatment presents liver decompensation.

Prediction of brain atrophy using three drug scores in neuroasymptomatic HIV-infected patients with controlled viremia

ABSTRACTBACKGROUND: Despite potent antiretroviral therapy, HIV still causes brain damage. Better penetration into the CNS and efficient elimination of monocyte/macrophages reservoirs are two main characteristics of an antiretroviral drug that could prevent brain damage. The aim of our study was to assess efficacy of three antiretroviral drug scores to predict brain atrophy in HIV-infected patients.METHODS:A cross sectional study consisting of 56 HIV-infected patients with controlled viremia, who had no clinically evident neurocognitive impairment. All patients had MRI of the head. A typical T2 transversal slice was analyzed and ventricles-brain ratio (VBr) as an overall brain atrophy index was calculated. Three antiretroviral drug scores were used and correlated with VBr: 2008 and 2010 CNS penetration effectiveness scores (SCPE2008 and SCPE2010) and the recently established monocyte efficacy (SME) score. A p-value <0.05 was considered significant.RESULTS:SCPE2010 was significantly associated with VBr in both univariate (r = -0.285, p = 0.033) and multivariate (ß = -0.299, p = 0.016) regression models, while SCPE2008 was not (r = -0.141, p = 0.300 and ß = -0.156,p = 0.214). SME was associated with VBr in multivariate model only (r = -0.297, p = 0.111 andß = -0.406, p = 0.029). Age and reported duration of HIV infection were also significant predictors of overall brain atrophy in multivariate regression models.CONCLUSIONS:Although based on similar type of research, SCPE2010 is a superior drug score compared to SCPE2008. SME is an efficient drug score in determining brain damage. Both SCPE2010 and SME scores should be taken into account in preventive strategies of brain atrophy and neurocognitive impairment in HIV-infected patients.

A typical T2 transversal slice was analyzed and ventricles-brain ratio (VBr) as an overall brain atrophy index was calculated. Three antiretroviral drug scores were used and correlated with VBr: 2008 and 2010 CNS penetration effectiveness scores (ΣCPE2008 and ΣCPE2010) and the recently established monocyte efficacy (ΣME) score. A p-value <0.05 was considered significant. RESULTS: ΣCPE2010 was significantly associated with VBr in both univariate (r=-0.285, p=0.033) and multivariate (ß=-0.299, p=0.016) regression models, while ΣCPE2008 was not (r=-0.141, p=0.300 and ß=-0.156, p=0.214). ΣME was associated with VBr in multivariate model only (r=-0.297, p=0.111 and ß=-0.406, p=0.029). Age and reported duration of HIV infection were also significant predictors of overall brain atrophy in multivariate regression models. CONCLUSIONS: Although based on similar type of research, ΣCPE2010 is a superior drug score compared to ΣCPE2008. ΣME is an efficient drug score in determining brain damage. Both ΣCPE2010 and ΣME scores should be taken into account in preventive strategies of brain atrophy and neurocognitive impairment in HIV-infected patients.

KNOWLEDGE AND ATTITUDES OF HEALTH CARE SCIENCE STUDENTS TOWARD OLDER PEOPLE.

INTRODUCTION: Education of health science students in geriatrics is important in order to provide optimal care for the growing number of elderly people because it is the attitudes of health professionals toward the elderly that play the key role in the quality of care provided. Therefore, the aim of this study was to assess the knowledge and attitudes of health care science students towards ageing and care for the elderly. MATERIAL AND METHODS: The present cross-sectional study was carried out on a sample of 130 students (medical, nursing and special education and rehabilitation) of the Faculty of Medicine, University of Novi Sad. The students were divided into two groups. The first group (E) included students having been taught geriatrics and nursing older adults and the other group (C) included students who had not been trained in this subject. The authors used Palmore's facts on Ageing Quiz for the knowledge evaluation and Kogan's Attitude toward Older People Scale for the attitude evaluation. RESULTS: The results of Facts on Aging Quiz showed the average level of students' knowledge and statistically significant difference between E and C group. The analysis of Kogan's Attitudes toward Old People Scale showed that both groups had neutral attitudes toward older people. Furthermore, a positive correlation between students' knowledge and attitudes was found. CONCLUSION: There is increasing evidence on the correlation between education, knowledge and attitudes toward older people which suggests that by acquiring better insights into all aspects of ageing through their education the students develop more positive attitudes and interest in working with older adults.

Epidemics of the central nervous system infections caused by West Nile virus in the territory of the South Backa District, Vojvodina, Serbia.

BACKGROUND/AIM: West Nile virus (WNV) is a neurotropic RNA virus particle which belongs to the Flaviviidae family, genus Flavivirus. It is sustained in arthropods within the transmission cycle between the mosquitoes and birds. Most commonly (80% of cases) WNV infections are asymptomatic among people. Less than 1% of patients develop neuroinvasive forms of the disease--meningitis, encephalitis, or acute flaccid paralysis. The aim of the research was to determine most common clinical and laboratory manifestations, to emphazise the presence of comorbidities and outcomes of treatment among patients with WNV infection. METHODS: This retrospective study, which was conducted in the period from January 1, 2012 to December 31, 2013, evaluated 32 patients who were diagnosed with WNV infection based on clinical findings, laboratory, and serological tests. To assess statistical significance we used χ2, and t-test. RESULTS: The study involved 22 (69%) males and 10 (31%) females aged from 31 to 65 years. On admission, there were 16 (50%) febrile individuals, 27 (84.4%) with positive meningeal signs, 17 (53.2%) with pathological neurological signs, and 10 (31.3%) with consciousness disorders. WNV infection was confirmed by the method enzyme linked immuno sorbent assay (ELISA) in all the patients, while Reverse Transcription Polymerase Chain Reaction (RT-PCR) test was positive in 3 (30%) of the tested patients. Cardiovascular comorbidities dominated in 7 (21.9%) of the cases. Full recovery was accomplished in 87.5% of the cases. CONCLUSION: The results of our study show that the absence of meningeal signs and fever on the day 7 of hospital treatment are indicators of good course and prognosis of neuroinvasive forms of WNV infection. Comorbidities do not increase the risk of disease. ELISA test is a sovereign diagnostic method. In most cases, after the administered symptomatic therapy, the complete recovery of patients was achieved.

Multivitamin mineral supplementation in patients with chronic fatigue syndrome.

BACKGROUND: Chronic fatigue syndrome (CFS) is characterized by medically unexplained persistent or reoccurring fatigue lasting at least 6 months. CFS has a multifactorial pathogenesis in which oxidative stress (OS) plays a prominent role. Treatment is with a vitamin and mineral supplement, but this therapeutic option so far has not been properly researched. MATERIAL AND METHODS: This prospective study included 38 women of reproductive age consecutively diagnosed by CDC definition of CFS and treated with a multivitamin mineral supplement. Before and after the 2-month supplementation, SOD activity was determined and patients self-assessed their improvement in 2 questionnaires: the Fibro Fatigue Scale (FFS) and the Quality of Life Scale (SF36). Results There was a significant improvement in SOD activity levels; and significant decreases in fatigue (p=0.0009), sleep disorders (p=0.008), autonomic nervous system symptoms (p=0.018), frequency and intensity of headaches (p=0.0001), and subjective feeling of infection (p=0.0002). No positive effect on quality of life was found. CONCLUSIONS: Treatment with a vitamin and mineral supplement could be a safe and easy way to improve symptoms and quality of life in patients with CFS.
