RESUMO
OBJECTIVE: Screening for abdominal aortic aneurysm (AAA) is recommended in high risk populations based on local conditions. Differences in lifestyle and risk factors between countries with different income status make risk stratification based on geographic location necessary. The majority of epidemiological studies on AAA have reported data from high income countries. The aim of this study was to explore the prevalence and risk factors for AAA in an upper middle income country in Eastern Europe. METHODS: A pilot screening project for AAA, supported by a mass media campaign, was conducted in 2023 in seven cities in Serbia. Ultrasound evaluation of the abdominal aorta was performed by a registered vascular surgeon on individuals who agreed to participate. Participants who attended screening completed a questionnaire on demographic and clinical information. To assess risk factors for AAA, univariable logistic regression analysis was performed to compute the odds ratio (OR) with 95% confidence interval (CI). Multivariable logistic regression was subsequently performed with adjustments for sex, age, family history of AAA, and other relevant factors. RESULTS: A total of 4 046 participants (51.2% male and 48.8% female; mean age 68.8 ± 7.6 years) responded to the campaign. An aneurysm was found in 195 (4.8%) screened individuals (8.2% of men and 1.3% of women). In males aged 50 - 64 years, the prevalence of AAA was 5.4%. Male sex, older age, family history of AAA, being a smoker or ex-smoker, being overweight, and alcohol consumption were predictors of AAA in the univariable analysis. After adjustments in the multivariable analysis, male sex (OR 8.04, 95% CI 4.87 - 13.28), older age (OR 1.04, 95% CI 1.02 - 1.07), positive family history (OR 2.47, 95% CI 1.61 - 3.78), smoker status (OR 3.10, 95% CI 2.10 - 4.59), ex-smoker status (OR 2.13, 95% CI 1.39 - 3.27), and being overweight (OR 1.85, 95% CI 1.25 - 2.74) were independent risk factors for AAA. CONCLUSION: The prevalence of AAA has not been reduced in all countries, and screening strategies might be changed based on local epidemiological data. The results of this pilot study underline the importance of exploring the prevalence of AAA in populations with a high prevalence of smoking.

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.

OBJECTIVE: This study aimed to analyse the influence of different methods of monitoring cerebral perfusion (MCP) on stroke, death, and use of intraluminal shunt during carotid endarterectomy (CEA). METHODS: A systematic review and network meta-analysis was conducted and registered in the PROSPERO registry (CRD42021246360). Medline, Embase, CENTRAL, and Web of Science were searched. Randomised controlled trials (RCTs) and cohort studies with > 50 participants that compared clinical outcomes for different MCP in patients undergoing CEA were included. Papers reporting one or a combination of two of the following MCPs were included in the analysis: awake testing (AT), near infrared spectroscopy (NIRS), electroencephalography (EEG), somatosensory evoked potential (SSEP), motor evoked potential (MEP), transcranial Doppler (TCD), and stump pressure (SP). A random effects network meta-analysis was performed using a binomial likelihood function with a specified logit link for peri-operative stroke or death and shunting as outcomes. Near infrared spectroscopy was excluded due to the lack of studies that could be used for statistical analysis. RESULTS: Of 1 834 publications, 17 studies (15 cohort studies and two RCTs) including 21 538 participants were incorporated in the quantitative analysis. Electroencephalography was used in the largest number of participants (7 429 participants, six studies), while AT was used in the highest number of studies (10 studies). All monitoring modalities had worse outcomes with respect to stroke or death when compared with AT, with ORs ranging between 1.3 (95% credible interval [CrI] 0.2 - 10.9) for SSEP + MEP and 3.1 (CrI 0.3 - 35.0) for patients monitored with a combination of EEG and TCD. However, the wide CrI indicated that there is no statistically significant difference between the monitoring methods. Patients monitored with a combination of EEG and TCD had the lowest odds of being shunted, while SP had the highest odds of being shunted, also with no statistically significant difference. CONCLUSION: There is a lack of high quality data on this topic in the literature. The present study showed no significant difference between monitoring methods investigated in the network meta-analysis.

INTRODUCTION: The aim of this systematic review and network meta-analysis was to compare the short-term results of fenestrated endovascular repair (FEVAR), chimney endovascular repair (ChEVAR), and open surgery (OS) for patients with juxta/pararenal abdominal aortic aneurysms (JAAA/PAAA). MATERIALS AND METHODS: MEDLINE, SCOPUS, and Web of Science were searched from inception to 1 July 2022. Any comparative studies investigating the results of two or three treatment strategies (ChEVAR, FEVAR, or OS) on clinical outcomes for patients with JAAA/PAAA were included. Analysed outcomes were 30-day mortality, acute kidney injury (AKI), major adverse cardiovascular events (MACE), and bowel ischaemia (BI). RESULTS: A total of 22 studies with 8853 patients were included in the analysis. FEVAR (OR = 0.58, 95%CrI 0.36-0.82) and ChEVAR (OR = 0.56, 95%CrI 0.28-1.02) were associated with lower 30-day mortality than OS. FEVAR (OR = 0.54, 95%CrI 0.33-0.85) was associated with lower risk of AKI than OS. FEVAR (OR = 0.43, 95%CrI 0.20-0.89) and ChEVAR (OR = 0.34, 95%CrI 0.10-0.93) compared to OS were associated with lower rates of BI. FEVAR (OR = 0.67, 95%CrI 0.49-0.90) and ChEVAR (OR = 0.61, 95%CrI 0.35-1.02) were associated with lower 30-day MACE risk than OS. FEVAR was associated with a higher rate of SCI compared to OS (OR = 4.90, 95%CrI 1.55-19.17). CONCLUSION: We found a clear benefit for FEVAR and ChEVAR versus OS in terms of reduced 30-day mortality, BI, and MACE, as well as AKI for FEVAR. This suggests that higher-risk patients might benefit from endovascular treatment of JAAA/PAAA; however, should be applied in clinical practice with caution, since long-term outcomes were outside of the scope of this review.

PURPOSE: The aim was to evaluate the total diagnostic interval (TDI) and presenting complaints in children with brain tumours in Serbia. METHODS: This study retrospectively analysed 212 children aged 0-18 years newly diagnosed with brain tumours in two tertiary centres from mid-March 2015 to mid-March 2020 covering virtually all children with brain tumours in Serbia. TDI was calculated as the difference between the date of diagnosis and the date of symptom onset presented as a median in weeks. This variable has been evaluable for 184 patients. RESULTS: Overall TDI was 6 weeks. TDI was significantly longer in patients with low-grade tumours (11 weeks) than in patients with high-grade tumours (4 weeks). Children with the most frequent complaints (headache, nausea/vomiting and gait disturbance) were more likely to be diagnosed sooner. Patients with a single complaint had significantly longer TDI (12.5 weeks) contrasted to patients with multiple complaints (5 weeks). CONCLUSION: TDI with a median of 6 weeks is similar to other developed countries. Our study supports the view that low-grade tumours will present later than high-grade tumours. Children with the commonest complaints and children with multiple complaints were more likely to be diagnosed sooner.

Central nervous system (CNS) tumors comprise around 20% of childhood malignancies. Germline variants in cancer predisposition genes (CPGs) are found in approximately 10% of pediatric patients with CNS tumors. This study aimed to characterize variants in CPGs in pediatric patients with CNS tumors and correlate these findings with clinically relevant data. Genomic DNA was isolated from the peripheral blood of 51 pediatric patients and further analyzed by the next-generation sequencing approach. Bioinformatic analysis was done using an "in-house" gene list panel, which included 144 genes related to pediatric brain tumors, and the gene list panel Neoplasm (HP:0002664). Our study found that 27% of pediatric patients with CNS tumors have a germline variant in some of the known CPGs, like ALK, APC, CHEK2, ELP1, MLH1, MSH2, NF1, NF2 and TP53. This study represents the first comprehensive evaluation of germline variants in pediatric patients with CNS tumors in the Western Balkans region. Our results indicate the necessity of genomic research to reveal the genetic basis of pediatric CNS tumors, as well as to define targets for the application and development of innovative therapeutics that form the basis of the upcoming era of personalized medicine.

The Death Attitude Profile-Revised (DAP-R), one of the most widely used scales for assessing death attitudes is a multidimensional questionnaire capable of measuring a wide range of attitudes towards death. The aim of our study was to assess the reliability and validity of the Serbian version of the DAP-R. The study was conducted in October 2022 and included a total of 547 students of the Faculty of Medicine University of Belgrade (FMUB). Based on Cronbach's alpha coefficient values, our data show good reliability of the DAP-RSp (Serbian version). In our study, the confirmatory factor analysis showed a good fit of the data to the original factor structure with minor discrepancy; compared to the original version (five factors), our analysis yielded one more factor (six factors in total), however, almost all items had factor loading >0.3 on the appropriate scale.
RESUMO
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.

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.

INTRODUCTION: Among different comorbidities occurring in multiple sclerosis (MS), the presence of malignant diseases in these patients is of the particular importance. The aim of this study was to determine the malignant diseases burden in a whole cohort of patients with MS in the Belgrade region, based on the Belgrade population registry data. MATERIAL AND METHODS: This study comprises 2725 MS patients from the MS Registry, which represents a source for all necessary demographic and clinical data. Firstly, the Registry was searched for all persons with MS who had cancer comorbidity, during the period 1996-2019. Diagnosis of cancer was validated by the patients' medical documentation. In order to investigate factors associated with the occurrence of any type of the cancer and/ or breast cancer only, in persons with MS, different logistic regression analyses were performed. RESULTS: A total of 64 persons with 69 malignant diseases were observed (prevalence 2.53%). The most frequent malignancies in males were skin cancer (50.0%) and in females, breast cancer (23.2%). The cumulative incidence of cancer comorbidity in persons with MS was 324.9 new cases per 100,000 person-years for the total population (137.6/100,000 in males and 403.6 per 100,000 in females). Comparison of cancer incidence rate between MS and general Belgrade population revealed lower risk for malignancy occurrence in the MS population in total (standardized incidence ratio, SIR = 0.58, 95% CI 0.16-1.49). CONCLUSIONS: Our findings demonstrate that MS patients in the Belgrade region have lower risk for the development of malignancy than age- and sex-matched general population.

Cognitive impairment is one of the most frequently reported symptoms in persons with multiple sclerosis (MS). The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) has been recommended as a standardized international screening and monitoring tool for brief cognitive assessment. The aim of our study was to assess the reliability and validity of the Serbian version of the BICAMS. A total of 500 relapsing-remitting MS (RRMS) patients and 69 age-, gender- and education-matched healthy control (HC) subjects were examined. All participants performed the BICAMS test battery, which includes the oral version of the Symbol Digit Modalities Test (SDMT), California Verbal Learning Test second edition (CVLT-II), and Brief Visuospatial Memory Test Revised (BVMTR). A randomly selected subset of patients were retested one to three weeks after baseline. Statistically significant differences between patients and HCs were evident on the SDMT and BVMTR (p<0.001). HCs had higher CVLT-II scores but this difference did not reach statistical significance (p=0.063). Cognitive impairment, defined as an abnormal test score on ≥1 subtest, was found in 62.9% of MS patients. There were statistically significant correlations between BICAMS scores and age, education, EDSS and disease duration in patient sample. Test-retest reliability was confirmed with Pearson correlation coefficient of 0.70 in all measures. This study supported the reliability and validity of the Serbian BICAMS, although the CVLT-II version tested here lacked sensitivity to detect MS compared to healthy volunteers.

BACKGROUND: Comorbidities occur frequently in persons with multiple sclerosis (MS). The aim of the present study was to determine the prevalence of the most common comorbidities in the population of MS patients in Belgrade, Serbia. MATERIAL AND METHODS: Data on diagnosed and fully documented comorbidities were taken from the Belgrade MS population registry. The list of explored comorbidities included cardiovascular, malignant, and autoimmune diseases; psychiatric disorders; epilepsy; and type 2 diabetes. In the data analysis, crude, age- and gender-specific, and age-adjusted prevalence was calculated. Additionally, comorbidities were analyzed in patients with various MS phenotypes. RESULTS: The most prevalent group of comorbidities were psychiatric (prevalence (Prev) = 20.59%, 95% CI 19.10-22.17) and cardiovascular comorbidities (Prev = 15.23%, 95% CI 13.93-16.63). The most prevalent single comorbidities were depression (Prev = 11.82%, 95% CI 10.64-13.11) and hypertension (Prev = 11.41%, 95% CI 10.25-12.68). Type 2 diabetes was significantly more prevalent in patients with primary progressive MS compared with the patients with relapsing-remitting and secondary progressive MS (p < 0.001). We found statistically significant positive correlation between number of comorbidities and progression index (p < 0.001). Patients treated with disease-modifying therapies (DMTs) had significantly higher risk of developing comorbidity, after treatment initiation, compared with those who were untreated (p = 0.001). CONCLUSIONS: Our study demonstrated high prevalence of comorbidities in persons with MS, with psychiatric and cardiovascular diseases being the most common. Furthermore, our findings confirmed the association of comorbidities with progression of disability and emphasized their role in treatment decision-making in MS.

Clostridium collagenase has provided superior clinical results in achieving digestion of immediate and accumulating devitalized collagen tissue. Recent studies suggest that debridement via Clostridium collagenase modulates a cellular response to foster an anti-inflammatory microenvironment milieu, allowing for a more coordinated healing response. In an effort to better understand its role in burn wounds, we evaluated Clostridium collagenase's ability to effectively minimize burn progression using the classic burn comb model in pigs. Following burn injury, wounds were treated with Clostridium collagenase or control vehicle daily and biopsied at various time points. Biopsies were evaluated for factors associated with progressing necrosis as well as inflammatory response associated with treatment. Data presented herein showed that Clostridium collagenase treatment prevented destruction of dermal collagen. Additionally, treatment with collagenase reduced necrosis (HMGB1) and apoptosis (CC3a) early in burn injuries, allowing for increased infiltration of cells and protecting tissue from conversion. Furthermore, early epidermal separation and epidermal loss with a clearly defined basement membrane was observed in the treated wounds. We also show that collagenase treatment provided an early and improved inflammatory response followed by faster resolution in neutrophils. In assessing the inflammatory response, collagenase-treated wounds exhibited significantly greater neutrophil influx at day 1, with macrophage recruitment throughout days 2 and 4. In further evaluation, macrophage polarization to MHC II and vascular network maintenance were significantly increased in collagenase-treated wounds, indicative of a pro-resolving macrophage environment. Taken together, these data validate the impact of clostridial collagenases in the pathophysiology of burn wounds and that they complement patient outcomes in the clinical scenario.

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.

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.

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.
RESUMO
AIM: To assess parental knowledge and attitudes related to MMR vaccination and to determine factors associated with parental decision whether to vaccinate their child with MMR vaccine in Serbian population. METHODS: The selection of participants was performed using multi-phase sampling. Seventeen out of the total 160 public health centers on the territory of Republic of Serbia were randomly selected. All parents of children up to the age of 7 who visited the pediatrician at the public health centers from June to August 2017 were recruited. Parents filled in an anonymous questionnaire regarding their knowledge, attitudes and practices in immunization with MMR vaccine. The relative contribution of different factors was explored by univariable and multivariable logistic regression analysis. RESULTS: The majority of parents were female (75.2%), with mean age of 34.3 ± 5.7 years, and the average age of children was 4.7 ± 2.4 years, 53.7% of them were girls. In the multivariable model, getting information on vaccination from a pediatrician was associated with 7.5 fold increased probability to vaccinate child with MMR vaccine (OR = 7.52; 95% CI 2.73-20.74; p<0.001), while previous vaccination of the child increased this chance two times (OR = 2.07; 95% CI 1.01-4.27; p = 0.048), and having two children was associated with 84% increase in chance of vaccinating child with MMR vaccine compared to having one child or three or more children (OR = 1.84; 95% CI 1.03-3.29; p = 0.040). CONCLUSION: Our study emphasized the key role of pediatricians in the formation of parental attitude on MMR vaccination of their child.

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.

Introduction: The health-related quality of life (HRQoL) of people with (Pw) multiple sclerosis (MS) is usually deteriorated. It has been recently suggested that comorbidities may have the negative influence on the quality of life of the PwMS, but according to the best of our knowledge, only one study investigated, although in a very small cohort, the impact of individual comorbidity on the quality of life of PwMS. The aim of our investigation was to assess, in an international, multicentric study, the impact of comorbid seizure/epilepsy on the HRQoL in PwMS. Methods: We conducted cross-sectional study at numerous neurological centers in Serbia, Croatia, Bulgaria, Montenegro, Northern Macedonia, and Bosnia and Herzegovina (Federation of Bosnia and Herzegovina and Republic of Srpska). For each patient, demographic and clinical data were collected, including Expanded disability status scale (EDSS) score. Beck Depression Inventory (BDI) and the 36-Item Short Form Health Survey (SF-36) questionnaires were administered to all patients. Results: The study comprised 326 PwMS in total, 127 PwMS with seizure/epilepsy and 209 PwMS without. Both mean Physical health composite (PHC) and mental health composite (MHC) scores, were statistically significantly higher in PwMS without seizure/epilepsy, implicating worse quality of life in PwMS with comorbid seizure/epilepsy. Presence of seizure/epilepsy in pwMS was statistically significant independent predictor of both PHC and MHC, in multivariate linear regression model after adjustment for potential confounding variables. The hierarchical multivariate regression analysis was performed in order to establish the most important predictors of the PHC and MHC of the SF-36, in PwMS with seizure/epilepsy; older age, higher level of disability, as measured by EDSS, higher depression score, drug-resistant epilepsy and shorter time since last seizure were found to significantly predict worse MHC score in PwMS with seizure/epilepsy. Discussion: Our results point to the possible role of theinterventions related to the adequate control of epilepsy along with improvement of the mental health status to be important in order to reduce MS burden in the PwMS with comorbid seizure/epilepsy.

 An important part of the wound healing process is the removal of necrotic tissue from a wound to promote healing. Enzymatic de- bridement is one of the widely used methods to accomplish this goal. Clostridium collagenase (C. collagenase) containing ointment is fre- quently used in clinics to debride wounds. In this work, the influence of metal salts and various types of surfactants on the enzymatic activ- ity of C. collagenase is tested. The relationship between charge and size of metal ions and surfactant structure is explained in the context of enzyme inhibition. Commonly used wound care products, such as cleansers, dressings, antimicrobial formulations, and silver dressings are tested with C. collagenase. The results are discussed in terms of enzyme compatibility with such materials, and recommendations for use of wound care accessories in conjunction with the debriding en- zyme are given, with the aim to help wound care providers make more educated choices towards accomplishing optimal therapy outcome. .
