Purpose: The aim of the study was to assess health-related quality of life (HRQoL) and contributing factors among parents of children with solid tumors in Serbia. Methods: The cross-sectional study included 51 parents of children treated for different solid tumors at the Institute of Oncology and Radiology of Serbia. Parents filled out validated Serbian version of SF-36 questionnaire. Hierarchical multiple regression analysis was conducted to identify predictors of total score of SF-36. Results: Almost all parents (94.1%) were mothers and average age was 38.6 ± 6.7 years. Majority of children had brain tumors (43.1%), followed by bone tumors (37.3%). The hierarchical regression analysis showed that socio-demographic characteristics explained 26% of the variance (p > 0.05) of the total score of SF-36. Addition of quality of life of children assessed by parents in the second model caused an increase of 21% in the variance explained (p < 0.05). After adding the Beck Depression Inventory score in the third block, an additional 18% of the variance in total score was explained (p < 0.05). Conclusions: This study showed that HRQoL measured by SF-36 in parents of children with cancer is strongly influenced by depression and quality of life of children assessed by parents. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.

The epidemic control approach was based on non-pharmacological measures in the first year of the COVID-19 pandemic, followed by vaccine uptake in the second year. Vaccine uptake depends on the individual attitude toward vaccination. The aim was to assess the changes in attitudes regarding COVID-19 vaccine protection during the pandemic and to determine the vaccination uptake concerning these attitudes. A panel study on COVID-19 vaccine attitudes and vaccination against COVID-19 was conducted in Belgrade, Serbia. The first survey was carried out in May–June 2020, and the second survey was organized in August–September 2021. During the baseline testing performed in 2020, 64.4% of respondents believed that the future vaccine against COVID-19 could protect against the COVID-19 disease, while 9.7% thought that it could not, and 25.9% were unsure. One year later, in the second survey, the percentage of participants with positive attitudes was slightly lower (64.7% vs. 62.5%). However, negative attitudes turned positive in 34% of cases, and 28.9% became unsure about vaccine protection (p < 0.001). Out of the 390 participants included in the study, 79.7% were vaccinated against COVID-19 until follow-up. There is a statistically significant difference in vaccination uptake compared to the baseline attitude about the protection of the COVID-19 vaccine. The main finding of our study is that the majority of participants who were vaccine hesitant during the baseline testing changed their opinion during the follow-up period. Additionally, the baseline attitude about the protection of the COVID-19 vaccine has been shown to be a potential determinant of vaccination uptake. © 2023 by the authors.

Purpose: To translate, culturally adapt and validate the Coronary Revascularisation Outcome Questionnaire (CROQ), a disease-specific tool for measuring health-related quality of life (HRQoL) in patients with ischaemic heart disease (IHD), into Serbian language (CROQ-S). Methods: Validation study was performed at the Clinic for Cardiac Surgery and Clinic for Cardiology, University Clinical Centre of Serbia. We included a convenience sample of 600 patients with IHD divided into four groups. Acceptability, reliability and validity of the CROQ-S were assessed. Results: CROQ-S was acceptable to patients as demonstrated by less than 1% of missing data for each single item. Cronbach's Alpha was higher than the criterion of 0.70 for all scales in each version except the Cognitive Functioning scale which only met this criterion in the CABG pre-revascularisation version. Mean values of item-total correlations were greater than 0.30 for all scales except the Cognitive Functioning scale in both the pre-revascularisation groups. Compared to the original version, exploratory factor analysis in our study showed more factors; however, the majority of items had a factor loading greater than 0.3 on the right scale. Correlations of CROQ-S scales with the 36-Item Short Form Health Survey and Seattle Angina Questionnaire showed the expected pattern whereby scales measuring similar constructs were most highly correlated. Conclusion: CROQ-S is an acceptable, reliable and valid disease-specific instrument for measuring HRQoL in this sample of Serbian speaking patients with IHD both before and after coronary revascularisation. However, the Cognitive Functioning scale did not meet all the psychometric criteria and further validation of its responsiveness is required. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Background: It has not been clarified yet if persons with multiple sclerosis (MS) are at increased risk to develop glucose metabolism dysregulation. The aims of the present study were to evaluate glucose metabolism characteristics in persons with MS and to compare it to the healthy individuals; to examine the association of glucose metabolism with the level of disability and its progression. Methods: The study enrolled 78 patients with MS and 26, comparable for age, gender and body mass index (BMI), healthy controls (HC). Disability and its progression were evaluated by the Expanded Disability Status Scale (EDSS) score, progression index (PI) and multiple sclerosis severity score (MSSS). All participants performed an oral glucose tolerance test (OGTT). Insulin and lipid parameters were analyzed. Results: Fasting glucose concentrations (5.3±0.7 in MS patients vs. 4.5±0.9 mmol/L in HC, p=0.001) and 2 hour post-load glucose concentrations were statistically significantly higher in MS patients compared with controls. Glucose levels at all different time points during OGTT, baseline insulin, Homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol and LDL were statistically significantly (p<0.05) associated with MS, in univariable logistic regression analysis. Glucose level at 120’ was independently associated with MS (OR=3.937, 95% CI 1.178-13.159, p=0.026), in the multivariable model. The prevalence of IR was 64.1% in the MS group compared to 30.8% in the control group (p=0.008), based on HOMA-IR. EDSS and Multiple sclerosis severity score (MSSS) were associated with glucose levels at different time points (p<0.05). According to the ROC analysis, best cut-off value for HOMA-IR is 2.3, providing both sensitivity and specificity of 66.7% in discriminating persons with MS and HC. Conclusion: Our results demonstrate the presence of higher prevalence of IR in MS patients compared to healthy individuals, and strong association between impaired glucose metabolism and disability. Finally, it has to be emphasized that further studies are warranted to confirm our findings implicating that MS patients have significantly higher risk of impaired glucose metabolism, which could suggest the potential importance of the performance of OGTT in patients with this disorder. © 2020 Elsevier B.V.

Aim: The aim of this study was to assess the prevalence of familial MS (fMS) in Belgrade MS population, discern the differences between the persons with fMS and sporadic MS, and to detect the presence of anticipation phenomenon in fMS patients. Methods: The data on the demographic and clinical characteristics of MS patients was obtained from the Belgrade MS population Registry. In cases of vertical transmission of MS, the family members were divided into the younger and older generation, in order to assess the potential presence of anticipation phenomenon. To adjust for follow-up time bias, a secondary analysis including only patients who had the onset of symptoms before 39 years (75.percentile), and those who were 39 + years, was performed. Results: The prevalence of fMS in Belgrade MS population is 6.4%. FMS cases had earlier age at MS symptom onset (30.4 vs. 32.3 years) compared to sporadic MS cohort. When comparing fMS cases across generations, the younger generation had significantly lower age at onset compared with the older one (25.8 vs. 35.7 years, p < 0.001). After adjustment for the different length of the follow-up, the difference in age at symptom onset between the groups was reduced, but it still existed and was statistically significant (30.0 years in younger vs. 36.4 years in older generation, p = 0.040). Conclusion: In our study, the analysis of fMS cases across generations, showed an earlier age of symptom onset in the younger generation, even after adjustment. These results indicate the possibility of existence of anticipation phenomenon. © Fondazione Società Italiana di Neurologia 2024.

Background: Multiple sclerosis (MS) is an immune-mediated disease that affects the central nervous system, which most likely results from the interplay between environmental and genetic factors. The aim of our study was to assess the effect of breastfeeding on the risk of developing familial multiple sclerosis (fMS) in persons with positive MS history, being the first such investigation performed in fMS cohort. Methods: A case-control study based on the Belgrade population MS Registry was conducted. Cases for the sporadic MS (sMS) control group were randomly selected from the Registry, and matched with individuals with fMS at a ratio of 1:1. Spouses of the persons with fMS were included as a healthy control (HC) group. A specific questionnaire that was previously validated was used to obtain the data. To evaluate risk factors associated with breastfeeding for fMS occurrence compared with sMS and HC, multinomial regression analysis was performed to compute the relative risk ratios (RRR) along with 95% confidence intervals (95% CI). The analysis was afterwards repeated, stratified by sex. Both models were adjusted for potential confounding factors. Results: A total of 393 participants were included in our case-control study, 131 per group. There were more individuals who were exclusively breastfed longer than six months in the sMS group compared to fMS group (RRR 2.01, 95% CI 1.22–3.32). After stratification by sex, exclusive breastfeeding was shown to be a protective factor for fMS only in male population, for individuals breastfed ≥4 months. The results of both the main and stratified analysis remained robust after adjustment. Conclusion: Our study findings indicate that breastfeeding reduces the risk of MS in infants with family history of the disease, although this protective effect may be limited to the male population. Further investigation into the differences in risk factors between fMS and sMS is warranted to gain a more comprehensive understanding of the disease. © 2023

The aim of this study was to assess attitudes and practice of blood donation among medical students. Medical students were recruited at Medical Faculty, University of Belgrade, Serbia. Of 973 students, 38.4% of freshmen and 41.4% of final year students have donated blood (χ2=0.918, p=0.186). Blood donors had significantly more positive attitude towards some aspects of blood donation. Being female, residing in a city other than the capital and previous blood donation experience were independent predictors of positive attitude towards being a blood donor to an unknown person. Efforts are required to augment blood donor pool among future physicians. © 2015 Elsevier Ltd.

Background Gait pattern is frequently impaired in multiple sclerosis (MS), however gait characteristics in patients with different MS phenotypes have not been fully elucidated. Methods We analyzed spatio-temporal gait pattern characteristics in patients with relapsing-remitting (RR, n=52) and primary-progressive (PP, n=18) MS in comparison with age-matched healthy controls (HC, n=40). All subjects performed a standardized simple walking task, a dual motor- motor task, a dual motor-mental task, and a triple combined motor-mental task at a GAITRite electronic walkway of 5.5 m active area. We measured: cycle time (CT), stride length (SL), swing time (ST), double support time (DST), gait velocity (GV) and calculated symmetry index (SI) for CT, SL and ST. Results With each task performed, CT and DST in the total MS group were significantly longer while SL was significantly shorter and GV significantly lower than in HC. ST was similar in the total MS patient group and HC. In both MS patients and HC, CT and DST increased and SL and GV decreased over repeated assessments. Dual and triple tasks while walking influenced walking performance in both MS patients and HC. Although patients with PPMS differed significantly from those with RRMS in the majority of gait parameters, the subgroup analysis in patients matched for age and disability (Expanded Disability Status Scale Score -EDSS, 3.0–5.0) showed similar gait performance in RRMS and PPMS patients having the same level of disability, except for CT and ST- symmetry parameters that were more impaired in the PPMS group. The EDSS score correlated significantly with CT, DST, SL and GV, but no significant correlation was found with ST except at the triple combined motor-mental task. Conclusion A disturbed gait pattern in MS patients with different MS phenotypes depends on disability and reflects a cognitive-motor interference. © 2017 Elsevier B.V.

Objectives: Investigation of the comorbidity burden in persons with multiple sclerosis (PwMS) has become increasingly important. The aim of this study was to investigate the relationships of cardiovascular disease (CVD) comorbidities and type 2 diabetes with the disability progression. Materials & Methods: The retrospective cohort study was conducted at the Clinic of Neurology, Belgrade. The Belgrade MS population Registry, which comprises 2725 active MS cases, was used as the source of data. The mean duration of the disease was 21.6 ± 12.5 years. Expanded Disability Status Scale (EDSS) was followed in all PwMS in the Registry. In the statistical analysis, the Cox proportional hazard regression analysis and Kaplan-Meier curve were performed. Results: Hypertension statistically significantly contributed to more rapid reaching investigated levels of irreversible disability (EDSS 4.0, 6.0, and 7.0), while the presence of any of the investigated CVD comorbidities and type 2 diabetes significantly contributed to faster reaching EDSS 4.0 and EDSS 6.0. In a multivariable model, progression index (PI) was singled out (HR = 3.171, p <.001), indicating that higher progression index (PI) was an independent predictor of CVD occurrence in MS patients. In the case of type 2 diabetes, PI (p <.001) and MS phenotype (p =.015) were statistically significant in multivariable Cox regression analysis. Conclusions: Our study confirms the impact of CVD comorbidities and type 2 diabetes in MS on the progression of disability as measured by EDSS in the large cohort of PwMS from the population Registry. © 2021 John Wiley & Sons A/S.

Background: A substantial autonomic nervous system (ANS) dysfunction has been described in multiple sclerosis (MS) and recently, also in neuromyelitis optica spectrum disorder (NMOSD). The prevalence of ANS symptoms contributes to the chronic symptom burden in both diseases. The aim of our study was to assess ANS dysfunction in people with (pw) NMOSD and MS, using the Composite Autonomic Symptom Score-31 (COMPASS-31), and additionally, to evaluate if ANS dysfunction have impact on the quality of life of these patients. Methods: We conducted cross-sectional study at three national referral neurological clinics in Serbia, Croatia, and Montenegro. A total of 180 consecutive subjects, 80 pwNMOSD and 100 pwMS, followed-up at these clinics, were enrolled in the study. Subjects included in the study completed: the validated versions of the COMPASS-31 and the Multiple Sclerosis Quality of Life-54 (MSQoL-54), and the Beck Depression Inventory (BDI). Results: This study demonstrated that the total COMPASS-31 score > 0.0, implicating the presence of ANS dysfunction, was detected in almost all NMOSD and MS study participants tested (80/80, and 97/100, respectively). Our findings showed that autonomic symptom burden was statistically significantly correlated with decreased quality of life, in both NMOSD and MS cohorts. The independent predictors of the better quality of life in pwNMOSD were lower autonomic burden, particularly the absence of the orthostatic intolerance (p = 0.005), along with lower EDSS and BDI score (p ≤ 0.001). Similarly, in pwMS, independent predictors were EDSS, BDI, orthostatic intolerance, and the total COMPASS-31 (p ≤ 0.001). Conclusion: Our study demonstrated that a significant proportion of persons with both NMOSD and MS have considerable dysautonomic symptom burden which is correlated with the decreased quality of life. Further investigations are warranted in order to optimize treatment interventions in MS and NMOSD. © 2023

Introduction: To assess incidence and mortality trends of acute myeloid leukemia (AML) in Belgrade (Serbia) in a 15-year period (from 1999 to 2013). Material and Methods: Data were obtained from the Cancer Registry of Serbia, Institute of Public Health of Serbia. Standardized incidence and mortality rates per 100,000 inhabitants were calculated by direct standardization method using World Standard Population. Analysis of raw data indicated single-digit numbers per year and per 5-year age cohorts. Therefore, we merged years of diagnosis to three-year intervals, creating so-called “moving averages”. We also merged study population to 10-year age cohorts. Results: Both incidence and mortality rates increased with age, i.e., the lowest rates were observed in the youngest age groups and the highest rates were observed in oldest age groups. In all age groups, except the youngest (15-24 years), AML incidence was statistically significantly higher in men compared with women. Average age-adjusted incidence was 2.73/100,000 (95% confidence interval (CI) 2.28-3.71). Average age-adjusted mortality was 1.81/100,000 (95% CI 1.30-2.26). Overall, there were no significant changes in incidence trend. Age-adjusted incidence rates had increasing tendency among men aged 65-74 years (B = 0.80, standard error (SE) = 0.11; p = 0.005) and in total population aged 65-74 years (B = 0.41, SE = 0.09; p = 0.023). Increasing tendency in incidence of AML among women was observed in age group >75 years (B = 0.63, SE = 0.14; p = 0.019). No changes of mortality trend were observed. Conclusion: There was no significant change in trends of AML from 1999 to 2013 in the population of Belgrade. © 2018 by the authors. Licensee MDPI, Basel, Switzerland.

The purpose of this study was to examine the association between exposure to indoor SHS and self-reported HRQoL among healthy non-smoking students at the University of Belgrade, Serbia and Kosovska Mitrovica located in the post-conflict Kosovo province. Students who presented at Student Public Health Center in Belgrade in 2009 and Kosovska Mitrovica in 2015 for mandatory health checks were invited to participate. Data were collected using socio-demographic and behavioral questionnaire, health-related quality of life questionnaire Short Form-36 (SF-36) and Beck Depression Inventory (BDI). A total of 82.3% students in Belgrade sample and 76.0% in Kosovska Mitrovica sample reported daily exposure to indoor SHS. After adjustment for socio-demographic characteristics and behavior, daily exposure to indoor SHS for more than 6 hours was associated with poorer Vitality (β = −5.55, 95% confidence interval [CI] −9.49, −1.61) and Mental Health (β = 5.00, 95% CI-8.94, −1.07) only among students at the University of Belgrade. This study showed that the association between longer daily indoor SHS exposure and poor mental health HRQoL was not consistent in non-conflict and post-conflict setting. This association was not found in a post-conflict setting. Strict no smoking policies are needed in student housing, university campuses and all public spaces. © 2020 Informa UK Limited, trading as Taylor & Francis Group.
