Objectives: A tribomechanically activated clinoptilolite (natural aluminosilicate mineral) has been used to increase growth in meat-producing animals, as an adjuvant in cancer therapy, and a heavy metal remover in humans. Because of its unique cation exchanging and chelating properties, we hypothesized that clinoptilolite may be beneficial for the treatment of dyslipidemia in the manner similar to bile acid sequestrants. Thus, specific aims of this pilot study were to orally administer clinoptilolite in different doses and granule size combinations to determine magnitude and time profile of changes in blood lipids. Design: A phase I/IIa prospective, open-label, uncontrolled, dose/granule size-ranging study (treatment phase 8 weeks, follow-up 6 weeks). Blood lipids were examined every 2 weeks. Settings: Outpatient clinic of a university-affiliated hospital. Subjects: Forty-one subjects (all white, mean age 57.6 ± 6.8 years, 17 women) with blood lipids above the normative limits divided into three groups. Intervention: A tribomechanically activated clinoptilolite was administered in three dose/grind combinations: 6 g/day of fine grind (6gF), 6 g/day of coarse grind (6gC), and 9 g/day of coarse grind (9gC). Outcome measures: Blood concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), high-density lipoprotein cholesterol (HDLc), and triglycerides (TG). Results: For the 3 groups combined, all lipid fractions significantly improved after 8 weeks of treatment (20-25%, p < 0.001), which reversed to baseline after 6 weeks of clinoptilolite withdrawal. Early (week 2) and the most pronounced decrease in TC and LDLc was observed in the 6gF group (19% and 23% in week 8, respectively), with no difference in HDLc and TG between the three dose/grind groups. No side effects were reported. Conclusions: These pilot results suggest that oral administration of clinoptilolite may improve lipid profile in individuals with dyslipidemia, which warrants further investigations. © Copyright 2017, Mary Ann Liebert, Inc.

Background and objective: Dysfunctional voiding (DV) presents relatively frequent problem in pediatric urologist practice. The necessity for implementation of DV evaluation in the pediatric population is of particular importance, since there is no clear consensus on the clinical assessment of such condition. The aims of our study were to evaluate the test/retest reliability and reproducibility of dysfunctional voiding and incontinence scoring system: Serbian version (DVISSSR) in patients with voiding and incontinence dysfunctions without structural deformities, and to estimate cut-of value for DVISS SR . Methods: The cross-sectional study included 57 children with voiding and incontinence dysfunctions and 30 healthy pediatric controls. For the evaluation of voiding and incontinence dysfunction we used DVISS. The forward-backward method was applied for translation of the DVISS questionnaire from English into Serbian language. Reproducibility was analyzed by Interclass Correlation Coefficient (ICC). Sensitivity and specificity of DVISS SR scores was done by receiver operating curve (ROC) curve. Results: There was a significant difference in DVISS SR score between patients and controls (p < 0.001). For reliability and reproducibility of the questionnaire, there was no significant difference between repeated measurements (p = 0.141), and strong reliability (ICC = 0.957; p < 0.001). Conclusion: We have demonstrated successful translation and validation of the DVISSSR score. Moreover, a reliable scoring system of children with voiding dysfunctions should include evaluations of symptom scoring systems at the multicentric level. © 2019 by the authors.

Introduction: Patients with spina bifida in the lumbosacral region usually have various degrees of motor and sensory dysfunctions of the lower extremities and anal sphincter. The aim of our study was to evaluate the distribution and differences in frequencies of affected muscles, number of affected muscles and degree of neurogenic lesion between patients with spina bifida occulta (SBO) and spina bifida aperta (SBA). Material and methods: In 100 patients with SB, 6 muscles in the lower limbs were separately analysed. Due to the number of affected muscles, we evaluated 5 groups of patients: with 1 affected muscle, 2 affected muscles, 3 affected muscles, 4 affected muscles and 5 affected muscles. Three degrees of neurogenic lesions were assessed: mild, moderate and severe. Results: The tibialis anterior muscle was most frequently affected in SB patients. The outer anal sphincter was frequently affected in the group of SBA patients. Single muscle affection is frequent in the group of patients with SBO, while in the group of patients with SBA, 4 muscles were significantly frequently affected. The great majority of patients (45.46%) with affected outer anal sphincter (OAS) in the group of SBO were without affection of other muscles, while for the SBA group it was for every third patient. Mild neurogenic lesion was significantly frequent in SBO patients, while severe form was significantly frequent in SBA patients. Conclusions: Patients with SBO usually present with mild to moderate clinical presentation, while multiple root involvement and severe degree of neurogenic lesion is associated more frequently with SBA.

BACKGROUND: We aimed to investigate the impact of eight-week aerobic exercise training on the risk of coronary heart disease onset by Duke Treadmill Score (DTS), metabolic equivalent of task (MET), and metabolic syndrome parameters, as well as correlation between those parameters in patients with type 2 diabetes mellitus. There is the clinical value of DTS for the risk stratification as well as strong association between DTS and the combined outcomes of cardiac death, nonfatal myocardial infarction, congestive heart failure and revascularization. METHODS: Sixty patients in stable clinical condition and well-regulated diabetic status conducted all phases of the study. Participants performed treadmill exercise testing using standard Bruce protocol before and after study. Rate of perceived exertion (RPE), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose levels (GLU), waist circumference (WC), triglyceride levels (TRI), high-sensitivity C-reactive protein (hs-CRP), probability of 5-year mortality (P5YM), probability of significant coronary heart disease (pCHD), probability of severe coronary disease (sCHD), DTS and METs levels were evaluated before and after study as well as correlation between DTS, METs and other parameters. RESULTS: The average values of DTS of 4.67 obtained before study indicated a moderate risk for CHD, while average values of 5.61 obtained after study indicated a low risk for CHD. Linear regression model stressed that variable DTS is statistically significant predictor, where higher values of DTS leads to the higher score values of METs. There is statistically significant difference in METs (P<0.001), RPE (P<0.001), sCHD (P=0.038), P5YM (P=0.033) values after study. CONCLUSIONS: Our study suggests that eight-week aerobic exercise training could significantly reduce the risk stratification by DTS from the intermediate to the moderate risk group for coronary heart disease in patients with type 2 diabetes mellitus. Lower values of DTS in women obtained in our research should be investigated in the future studies. Additionally, we have shown that increasing in METs will ultimately bring to decreased mortality in participants with diabetes mellitus type 2 and could significantly improve cardio-metabolic health that indicates the enormous potential value of exercise training. © 2019 EDIZIONI MINERVA MEDICA

INTRODUCTION: An aberrant or accessory crossing renal vessel (CV) leading to the lower pole of the kidney is the most common extrinsic cause of uretero pelvic obstruction(UPf) obstruction in a child and young adolescent. There is still controversy regarding there functional significance in obstruction Preoperative identification of such vessels may influence surgical management. OBJECTIVE: First aim is to determine the value of magnetic resonance (MR) urography in detecting crossing vessels children with UPf obstruction,comparing the data with postoperative findings and the second one is to evaluate morphologic and functional parameters in these hydronephrotic kidneys. MATERIALS AND METHODS: Between June 2009 and December 2012 we retrospectively reviewed MR urography records of one hundred and nine children with unilateral hydronephrosis at the University Children's Hospital. 68 (62.4%) were male and 41 (37.6%) were female,median age was 6.5 ± 5.7. Of the total number of patients, 30 (27%) underwent pyeloplasty, while 79 (72.5%) did not. The age at surgery ranged from 0.3 to 18 years (median 6.6 years). The indication for surgery was based on standard criteria (obstructed renal transit time with or without altered renal function of vDRF < 40%), and did not depend on the presence or absence of a crossing vessel. Consensus reviewes of the urography studies were compared with surgical findings. RESULTS: A crossing vessel (CV) was found upon surgery in 9 (33%) of 30 kidneys.On MRU, there was no crossing vessel in 21 kidneys, confirmed at surgery in 18. A crossing vessel was detected with MRU in 9 kidneys and confirmed at surgery in 6. Thus, the sensitivity of MRU was 66.7%, the specificity was 85.7%, the positive predictive value was 66.7%, the negative predictive value was 85-7% and the accuracy was 80%. There was no statistically significant difference in the detection of crossing vessels between MR urography and surgery (p = 0.004 and p < 0.01 respectively). Overall, MRU and surgery showed good agreement (K = 0.524). CONCLUSION: Based on our results we suggest that MR urography is a reliable and safe diagnostic tool to determine crossing vessels in selected children with UPJ obstruction. Thus, MRU can substitute for other imaging modalities and provide detailed information about the morphology and function of the affected kidney.

Our study aimed to analyze the reliability, consistency, and temporal stability of the Alberta Infant Motor Scale (AIMS) in Serbian infants. Additionally, we aimed to present a percentile distribution of AIMS in the tested population. The prospective study included 60 infants that were divided into three age groups: 0–3 months, 4–7 months, and 8–14 months. The Serbian version of AIMS was tested by two raters on two different occasions (test/retest) with a five day period between tests. The observed inter-rater reliability (intraclass correlation coefficient (ICC)) was more than 0.75 for all AIMS scores, except for standing (ICC 0.655 = moderate) in the age group of 4–7 months on retest between raters. The observed intra-rater reliability (ICC) was more than 0.75 for all AIMS scores except standing (ICC 0.655 = moderate) in the age group 4–7 months in test–retest for Rater One, and for sitting (ICC 0.671 = moderate) and standing (ICC 0.725 = moderate) in the age group between 0–3 months on test–retest for Rater Two. The Serbian version of AIMS was shown to have high consistency and high reliability with good to high temporal stability. Thus, it can be used in the evaluation of infants’ motor development in Serbia. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

Background and Objectives: The aim of this study was to validate the Serbian version of the Boston Carpal Tunnel Questionnaire (BCTQ) and to evaluate temporal stability for the purpose of its implementation in the evaluation of Serbian patients with carpal tunnel syndrome (CTS). Materials and Methods: For the validation of the Serbian version of the BCTQ (BCTQSR), we tested 69 individuals with diagnosed CTS that were referred for a conservative treatment at the Institute for Rehabilitation. Neurophysiological tests were used for the electrophysiological grading (EG) of CTS severity in the study sample. The final version of the BCTQSR was given to the tested participants from the study on two occasions: test and retest, with a five-day period between the two measurements. Results: The mean value for the symptom severity subscale (SSS) of the BCTQSR was 3.01 ± 0.94; for the functional status subscale (FSS) of the BCTQSR it was 2.85 ± 1.00. Cronbach’s α for the SSS was 0.91 and 0.93 for the FSS. The intraclass correlation coefficients (ICCs) concerning the test–retest were significant (p < 0.001) and were 0.949 for the SSS and 0.959 for the FSS. Those with a higher EG grade had higher values of the SSS and FSS but without a statistical significance (p = 0.103 and p = 0.053, respectively). The intercorrelation of the BCTQSR subscales (SSS and FSS) on the test was significant (p < 0.001) with a correlation coefficient equal to 0.777. Conclusion: The Serbian version of the BCTQ (BCTQSR) was successfully culturally adopted. The BCTQSR was a valid and reliable instrument for the measurement of symptom severity and functional status in adults with CTS. Therefore, it can be used in clinical practice for patients with CTS. © 2022 by the authors.

We aimed to evaluate the prevalence of sociodemographic factors with the presence and different degrees of walking difficulties in elderly above 65 years, and to analyze association between evaluated variables and the presence and degree of waking difficulties. In the population based study, 3540 individuals age above 65 years from Serbia were recruited. Further predictors were analyzed: gender, age, level of education, marital status, body mass index (BMI), index of well-being and place of residence. We assessed difficulty in walking half a km on level ground without the use of any aid (Group-1); and difficulty in walking up or down 12 steps (Group-2). Walking difficulties were categorized as no difficulty, some difficulty, a lot of difficulty and cannot do at all. For present difficulty significant predictors were: age (Group-1 (OR-3.022)/Group-2 (OR-3.825)), gender (Group-1 (OR-0.337)/Group-2 (OR-0.311)), educational level (Group-1 (OR-0.689)/Group-2 (OR-0.556)) and place of residence (Group-2 (OR-1.523)) while for non-performing the task, significant predictors were: age (Group-1 (OR-1.998)/Group-2 (OR-2.096)), gender (Group-1 (OR-0.629)/Group-2 (OR-0.495)), BMI (Group-1 (OR-1.219)/Group-2 (OR-1.305)), marital status (Group-1 (OR 0.764)/Group-2 (OR-0.769)), educational level (Group-1 (OR-0.679)/Group-2 (OR-0.719)) and index of well-being (Group-2 (OR-0.764)). Understanding of predictors, and their role on functional decline in elderly is of great importance for the development of specific population-based health programs to prevent further functional loss and preserve achieved functional gains. © 2018 by the authors.

Planning and adjusting health capacities to meet the needs of refugees is a constant issue for transit and destination countries following the 2015/2016 Western Balkans refugee crisis. Understanding this crisis is important for taking the right steps in the future. The study informs about the prediction of the refugees’ health needs and demands for services in correspondence to political decision-making during 2015/2016 Western Balkan Refugee Crisis. Time series analysis, linear regression, and correlation analyses modelled the weekly flux of arrivals of more than half a million refugees to Serbia and the European Union, changes in the utilization of health care services, and disease diagnoses. With strategic planning, in the event of a recurrence of the refugee crises, the demand for health care services in the transit country could increase by 63 (95% CI: 21–105) for every additional 1000 refugees. © 2020 by the authors.

Background and objectives: Pediatric Outcome Data Collection Instrument (PODCI) is among the most described scales developed to evaluate the physical status of children and adolescents with various musculoskeletal disorders. We aimed to translate PODCI from English to Serbian, culturally adopt items and domains, evaluate the temporal stability, internal consistency and the test–retest reliability of PODCISR in children with obstetrical brachial plexus lesion (OBPL), and finally, to test the construct validity of PODCISR against muscular manual test (MMT) Materials and Methods: The study included 48 eligible participants aged between 2 and 10 years with OBPL. The MMT was used to test the construct validity. Results: There were no significant differences (p > 0.05) between test and retest for all PODCISR domains. Correlations for all tested domains with MMT were statistically significant except for biceps muscle and domains II and IV. Cronbach’s alpha value of the Global Functioning Scale was good and equaled 0.838 for test and 0.832 for retest session. Cronbach’s α was more than 0.600 for all PODCISR domains except for Domain II and for Domain IV. The observed Test–Retest ICC for all PODCISR domains scores ranged from 0.899 to 0.996. Conclusion: The Serbian version of PODCI (PODCISR) was successfully translated and transculturally adopted. It has satisfactory temporal stability, construct validity and test–retest reliability as well as relevant internal consistency. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

Objective: The aims of our study were to translate the dysfunctional voiding symptom score (DVSS) from English to Serbian; culturally adopt the items; assess the internal consistency and the test–retest reliability of DVSSSR in patients with dysfunctional voiding (DV); evaluate and test the construct and divergent validity of DVSSSR against demographic parameters (gender and education); and examine the level of explained variability for each item of DVSSSR against demographic parameters (gender and education). Methods: The cross-sectional observational study included 50 patients with dysfunctional voiding aged 5 years and above. The DVSS questionnaire was translated from English into Serbian by the forward–backward method. Internal consistency was assessed with Cronbach α and test–retest reliability with intraclass correlation coefficient (ICC). For validity testing we performed construct and divergent validity analyses. Results: There was excellent internal consistency for every item except for Item 6 (0.787) and Item 3 (0.864), where internal consistency was good. The observed test/retest ICC for average measures was more than 0.75 (excellent) for all DVSSSR items. Gender and educational level does not correlate significantly with each item of DVSSSR (p > 0.05). For divergent validity, there were no significant differences in mean values of each item of DVSSSR between genders and different levels of education (p > 0.05). Variability that can be explained for gender and educational level was below 10%. Conclusion: Translated DVSSSR is of adequate validity and reliability for assessing DV in children. © 2018 by the authors. Licensee MDPI, Basel, Switzerland.

We assessed the quality of life of children with developmental dysplasia of the hip (DDH) treated surgically, through analysis of leg length discrepancy, quality of walking and presence of pain in 39 children with DDH between 1991 and 2011 at the University Children's Hospital in Belgrade. Salter's innominate osteotomy combined with derotation and femoral bone shortening was performed. Patients were divided into 3 groups based on their age at operation: the first group included participants operated at age up to 24 months, the second group between 24 and 48 months and the third group above 48 months of life. In the first group, leg length discrepancy was present in 30.76% and mean leg shortening was 0.63cm, versus 27.77% and 1.30 cm in the second group and 37.50% and 1.50 cm in the third group. Children with DDH that were operated earlier in life had less leg shortening and did not display any significant asymmetry of walking. © 2013, Acta Orthopædica Belgica.
