Pereira JG, Leon LAA, de Almeida NAA, Raposo-Vedovi JV, Fontes-Dantas FL, Farinhas JGD, Pereira VCSR, Alves-Leon SV, de Paula VS. Higher frequency of Human herpesvirus-6 (HHV-6) viral DNA simultaneously with low frequency of Epstein-Barr virus (EBV) viral DNA in a cohort of multiple sclerosis patients from Rio de Janeiro, Brazil. Mult Scler Relat Disord 2023; 76:104747.

Abstract
Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease of the central nervous system (CNS). The etiology of MS is not well understood, but it's likely one of the genetic and environmental factors. Approximately 85% of patients have relapsing-remitting MS (RRMS), while 10-15% have primary progressive MS (PPMS). Epstein-Barr virus (EBV) and Human herpesvirus 6 (HHV-6), members of the human Herpesviridae family, are strong candidates for representing the macroenvironmental factors associated with MS) pathogenesis. Antigenic mimicry of EBV involving B-cells has been implicate in MS risk factors and concomitance of EBV and HHV-6 latent infection has been associated to inflammatory MS cascade. To verify the possible role of EBV and HHV-6 as triggering or aggravating factors in RRMS and PPMS, we compare their frequency in blood samples collected from 166 MS patients. The presence of herpes DNA was searched by real-time PCR (qPCR). The frequency of EBV and HHV-6 in MS patients were 1.8% (3/166) and 8.9% (14/166), respectively. Among the positive patients, 100% (3/3) EBV and 85.8% (12/14) HHV-6 are RRMS and 14.4% (2/14) HHV-6 are PPMS. Detection of EBV was 1.2% (2/166) and HHV-6 was 0.6% (1/166) in blood donors. About clinical phenotype of these patients, incomplete multifocal myelitis, and optic neuritis were the main CNS manifestations. These are the first data about concomitant infection of these viruses in MS patients from Brazil. Up to date, our findings confirm a higher prevalence in female with MS and a high frequency of EBV and HHV-6 in RRMS patients.

Abstract
Multiple sclerosis (MS) is an autoimmune disease characterized by demyelination and axonal loss of the central nervous system (CNS). Despite its spread throughout the world, the mechanisms that determine its onset are still to be defined. Immunological, genetic, viral, and environmental factors and exposure to chemicals may trigger MS. Many studies have highlighted the anti-inflammatory and anti-oxidant effects of medicinal herbs, which make them a natural and complementary treatment for neurodegenerative diseases. A severe reduction of several MS symptoms occurs with herbal therapy. Thus, the request for medicinal plants with potential beneficial effects, for MS patients, is constantly increasing. Consequently, a production increase needs. Unfortunately, many medicinal herbs were untested and their action mechanism, possible adverse effects, contraindications, or interactions with other drugs, are poorly or not investigated. Keeping in mind the pathological mechanisms of MS and the oxidative damages and mitochondrial dysfunctions induced by pesticides, it is important to understand if pesticides used to increase agricultural productivity and their residues in medicinal plants, may increase the risk of developing MS in both workers and consumers. Studies providing some indication about the relationship between environmental exposure to pesticides and MS disease incidence are few, fragmentary, and discordant. The aim of this article is to provide a glance at the therapeutic potential of medicinal plants and at the risk for MS onset of pesticides used by medicinal plant growers and present in medicinal herbs.

Abstract
Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system. Cognition is not routinely assessed in patients with MS though they frequently have cognitive complaints or dysfunction. Objective The aim of this study was to compare the cognitive status of patients with MS with age, sex, and schooling matched controls and to evaluate the potential influence of clinical parameters on cognition. Methods A total of 35 patients with MS (mean±SD age 37.9 years±11.44, M/F: 12/23) and 33 healthy controls (mean±SD age 38.8 years±12.6, M/F: 12/21) were enrolled in this study. All subjects underwent a structured clinical assessment and the cognitive tools are as follows: Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), Rey Auditory Verbal Learning Test (RAVLT), Digit Span, and Verbal Fluency Tests (letters F, A, and S and animal category). Psychopathology was assessed with the Mini International Neuropsychiatric Interview and the Beck Depression Inventory (BDI). The Expanded Disability Status Scale (EDSS) was used for patients. Results Patients performed worse than controls in almost all tests, with approximately 70% of patients presenting cognitive impairment. The most affected cognitive domain was episodic memory (45.7%), followed by verbal fluency (42.8%) and information processing speed (22.8%). SDMT was inversely correlated with disease severity, as assessed by the EDSS. Depression did not influence cognitive performance in this cohort. Conclusions Cognitive dysfunction is common among patients with MS. While motor impairment was associated with information processing speed, depression did not influence cognitive performance.

Abstract
Dealing with paediatric-onset multiple sclerosis is particularly challenging for the young patients and their families, due to its unpredictable symptoms and uncertain outcome. This review aimed at synthesising the qualitative evidence regarding the perspectives about paediatric-onset multiple sclerosis, as expressed by the patients and/or their parents. A literature search was conducted on PubMed and CINAHL. The advanced multi-field search allowed to perform an abstract/title search in both databases, using keywords, combined through Boolean operators. Additional search strategies were adopted: searching the reference list of the selected papers; searching for key authors in the field. All the relevant papers were thoroughly revised using The Joanna Briggs Institute’s data extraction form for qualitative evidence as a guidance. Eight papers were selected. The analysis of these papers allowed to identify some common issues pertaining paediatric-onset multiple sclerosis: (1) onset of symptoms, (2) diagnostic process, (3) reaction to the diagnosis, (4) management and acceptance of multiple sclerosis. The burden of multiple sclerosis was confirmed. However, the young patients and their parents can adjust to the disease. Both the community and the health care professionals must strive to prevent the families dealing with multiple sclerosis from experiencing solitude and rejection.

Abstract
BACKGROUND Multiple sclerosis progression and disability can be rated differently by healthcare professionals. Therefore, how physicians perceive the disease can impact treatment decisions. There are no previous studies on this matter. OBJECTIVE To translate and transculturally validate the Revised Illness Perception Questionnaire for Healthcare Professionals (IPQ-R HP), for use in Brazilian Portuguese. METHODS The process used to validate the IPQ-R HP was based on the steps presented in the guide proposed by Dorcas Beaton. The final version of the IPQ-R HP had 38 questions, divided into seven different dimensions to assess the patient's disease. Also, two clinical cases that were representative of real-life patients with multiple sclerosis (MS) were assembled to consider the two main profiles of the disease. We applied the questionnaire to neurologists at the Federal University of São Paulo (UNIFESP) to assess their perception of MS. These doctors also answered a brief survey to establish the profile of the interviewees. For statistical analysis, we used Bayesian CFA models and kappa statistics. CONCLUSIONS The kappa statistics showed a general agreement of 0.4. For the Bayesian CFAs with seven-factor correlation solution, we had a poor fit for case 1 with a 95% confidence interval ranging from -52.893 to 273.797 and a PPP of 0.107. Regarding case 2, the model did not converge even after 50,000 iterations, which indicated that the specified model (i.e. seven-factor correlation solution) for case 2 was inadmissible. Thus, the IPQ-R HP questionnaire in Brazilian Portuguese has not been validated.

Abstract
BACKGROUND To improve the comparability of multiple sclerosis (MS) prevalence across Brazilian regions, the Brazilian Committee for Treatment and Research in MS has implemented a standardized approach to assess the prevalence of the disease in five key cities, which were deemed representative of their regions in terms of socio-geographical features and where in-person revision of each case was feasible. OBJECTIVE To report the point-prevalence of MS in Passo Fundo, one of the key cities in Southern Brazil. METHODS We sought to identify all MS patients who were living in Passo Fundo on July 1st, 2015. The primary source for case ascertainment was records from the offices of neurologists and neurosurgeons practicing in the city. Multiple secondary sources were used to maximize identification of cases. All patients underwent in-person review of the diagnosis by a panel of neurologists with experience in MS. RESULTS We identified 52 MS patients living in Passo Fundo on July 1st, 2015. The point-prevalence rate for MS was 26.4/100,000 population (95% confidence interval, 19.7 to 34.6/100,000). Among the MS cases, 42 (80.8%) were female, for a sex ratio of 4.2:1. Forty-six cases (88.5%) were categorized as relapsing-remitting MS, and the remaining 6 cases, as secondary progressive MS (11.5%). Other epidemiological and clinical features were comparable to national and international MS populations. CONCLUSIONS The prevalence of MS in Passo Fundo is one of the highest reported in Brazil so far. Studies in other key Brazilian cities, using the same methodology, are currently being carried out.

Abstract
BACKGROUND There is scarce epidemiological data on Multiple Sclerosis (MS) in Latin America. National epidemiological studies are needed to guide the health policy related to MS. OBJECTIVE To determine MS national prevalence in Peru and describe clinical and epidemiological characteristics of the disease. METHODS We conducted a cross-sectional prevalence study in Peru's four largest regions using two sources. We included adult patients diagnosed with MS by a neurologist using the McDonald criteria. We performed a capture-recapture analysis using the nearly unbiased estimator model, and calculated prevalence as the proportion of the adult Peruvian population in 2016. Additionally, we summarized patients epidemiological and clinical characteristics. RESULTS We identified 417 cases: 135 from the first source and 282 from the one. We found a point prevalence of 9.12 cases per 100 000 inhabitants (95% CI: 5.6 - 12.6). The age range was 35 to 45 years-old, and 51.9% were female. The most common type of MS was relapsing-remitting (79.3%) and the most frequent treatment was subcutaneous IFN-1b (40.7%). CONCLUSION Peru has a medium MS prevalence compared to other Latin American countries. Lima is the region with the highest number of cases, with similar clinical characteristics to other countries in the region.

Abstract
BACKGROUND Oropharyngeal dysphagia is a common symptom of many neurological diseases, including Multiple Sclerosis (MS). Early identification of the risk of dysphagia in neurological patients is very important for early referral for specialized evaluations of oropharyngeal swallowing and treatments. The Dysphagia in Multiple Sclerosis (DYMUS) questionnaire has been translated and validated in different countries over the last 10 years. We aimed to analyze the accuracy of the Brazilian Portuguese version of the DYMUS (DYMUS-BR) questionnaire in identifying dysphagia in patients with MS. METHODS The DYMUS questionnaire and a videofluorographic swallowing study (VFSS) were conducted in 30 patients with MS. Dysphagia was identified by at least one abnormal response and was considered alarming when the DYMUS scores were equal to or higher than 3. Patients were considered to have dysphagia in the VFSS when one or more signs of impairment in the efficiency and/or safety of swallowing were detected. RESULTS According to the initial self-assessment, 37% (N = 11) of patients with MS self-reported with dysphagia. According to the DYMUS-BR scores, 53% (N = 16) of the patients with MS were classified as having dysphagia. The sensitivity, specificity, and positive and negative predictive values of the DYMUS-BR questionnaire for the detection of dysphagia as measured by the VFSS were 50% [95% confidence interval (CI) 29-71], 78% (95% CI 61-90), 60% (95% CI 42-76), and 70% (95% CI 60-78), respectively. The area under the receiver-operating characteristic curve for detecting dysphagia was 64% (95% CI 49-79). CONCLUSION The accuracy of the DYMUS-BR questionnaire is poor to detect mild swallowing impairment in patients with MS. However, we suggest longitudinal follow-up in patients with low DYMUS-BR scores for early detection of oropharyngeal dysphagia.

Abstract
INTRODUCTION Multiple sclerosis (MS) is a chronic inflammatory demyelinating autoimmune disease that affects the central nervous system. Since immune system plays a key role in this disease, patients with MS can present higher risk of infections. PURPOSE This study aimed to investigate the prevalence of Candida spp. in the oral cavity of MS patients in relation to a control group METHODS: In total, 100 individuals were selected: 55 diagnosed with MS and 45 healthy individuals (control group). Saliva samples were collected and seeded in culture media selecting for Candida. Following an incubation period of 48 h, colony-forming units (CFU mL-1) were counted and colonies were isolated for Candida species identification by multiplex PCR. The results were analysed by chi-squared and Mann-Whitney U statistical tests considering a significance level of 5%. RESULTS Candida spp. were confirmed in the oral cavity of 50.09% patients in the MS group and 35.55% individuals in the control group. In individuals positive for the growth of Candida spp., the median values of Candida colonies were 220 CFU mL-1 for the MS group and 120 CFU mL-1 for the control group. However, no statistically significant differences were observed between groups for both prevalence and CFU mL-1 count. Of the Candida species identified, 73.91% were C. albicans, 21.73% C. glabrata, 2.17% C. tropicalis, and 2.17% C. krusei. CONCLUSIONS The colonization of Candida spp. in the oral cavity of individuals with multiple sclerosis was higher than in the control group; however these findings were not proven to be statistically significant.

Abstract
OBJECTIVE To describe the employment status of Brazilians with multiple sclerosis (MS). METHODS Analysis of a cross-sectional online survey including questions on demographic and occupational status at the time of diagnosis and survey completion, and time from the first symptom to diagnosis. RESULTS Of those who answered the survey, 804 Brazilians with MS were included. Median age of onset and current age were 28.3 and 36.2 years; median time to diagnosis and disease duration were 2.7 and 7.9 years; 67% held a university degree and 29% finished high school; 94% had a paid occupation contributing to the family income at least once in their lives, 77% were employed at the time of diagnosis but only 59% were employed at the time of survey. Longer disease duration, longer time to diagnosis and younger age at the first symptom, were identified as factors correlated with being unemployed. CONCLUSIONS The rate of unemployment doubled after the first symptoms of MS, and only 59% of highly-educated people with MS in their productive years were employed. The longer time to diagnosis may imply treatment delay, and strategies focusing on early diagnosis and adequate treatment may favor employment retention and reduce disability related costs, such as social benefits and pension fund use.

Abstract
BACKGROUND Physiological factors such as muscle weakness and balance could explain declines in walking distance by multiple sclerosis (MS) patients. The purpose of this study was to characterize levels and examine associations among decline in walking distance, balance and muscular strength in women with mild MS. METHODS Participants included 28 women with mild relapsing-remitting MS and 21 women without MS. We executed the 6-min walk test (6MWT) to verify declines in walking distance. Isokinetic knee flexion (KF) and extension (KE) muscle strength was measured using a dynamometer. Balance was quantified using a force platform, with eyes open and closed, on a rigid and foam surface. RESULTS The MS patients presented declines in walking, lower KF muscle strength, and worse balance than controls. KF strength and balance correlated with walking in the MS group. The KF strength explained differences between groups in walking. The KF strength and balance presented as predictors of walking slowing down in the 6MWT, in mild MS. CONCLUSION Women with mild MS have strength impairment of knee flexor muscles and balance control impairment that may explain walking related motor fatigability during prolonged walking.
