Background/aims
The prevalence of overweight/obesity is a major problem in the world, and the number of MS cases is increasing. This literature study examines the relationship between overweight/obesity in children and adolescents and later occurrence of MS.Method
This is a complete literature survey. The search database is primarily Pubmed using MeSH terms “multiple sclerosis”, “obesity”, and “overweight”, and text words not to restrict searches.Results
All included studies show a link between being overweight/obese and the presence of MS among people below 20 years of age. The relation is especially true for young girls. The same relation in boys is not significant.Conclusion
The literature survey convincingly revealed a link between young overweight/obese and occurrence of MS, in particular for girls. There is a need for more and larger studies to investigate the molecular mechanisms that link obesity and MS.2.
Background
The risk of developing progressive multifocal leukoencephalopathy in natalizumab-treated multiple sclerosis (MS) patients is related to serum anti-JCV antibody (JCVAb) index. However, the correlation of JCVAb index with other disease-modifying treatments (DMTs) is not well understood.Objective
In this study, we investigated the JCVAb seropositivity rate/JCVAb indexes and its correlation with clinical profiles in Japanese MS patients, and the relationship between JCVAb indexes and DMTs.Methods
JCVAb indexes were measured in 149 serum samples from 105 patients with MS. JCVAb indexes and seropositivity, and their correlation with age, sex, disease duration, Kurtzke expanded disability status scale and the duration of the DMTs were evaluated in each patient.Results
JCVAb was positive in 73 of 105 MS patients. Within 40 fingolimod-treated patients, 27 were positive for JCVAb and JCVAb indexes were positively correlated with the duration of fingolimod treatment. No significant relation was found between JCVAb indexes and the duration of treatment for the other disease-modifying drugs.Conclusion
JCVAb seropositivity was comparatively high in Japanese MS patients. Fingolimod treatment is likely to increase serum JCVAb index, possibly leading to the development of PML. Therefore, it is advised that JCVAb index should be serially monitored during fingolimod treatment to decrease PML risk.3.
Background
Treatment choice in multiple sclerosis (MS) is crucial for optimizing risk–benefit profile.Objective
To assess fingolimod (FTY) effectiveness and identify baseline features associated to disease activity in a large Italian cohort of Relapsing–Remitting (RR) MS patients.Methods
Three-hundred sixty-seven RRMS patients starting FTY treatment at San Raffaele Hospital (Milan-Italy) underwent clinical and MRI evaluations for 2 years. Treatment response was assessed considering the proportion of patients with no evidence of disease activity (NEDA) and recording the time to first relapse. Primary analyses were performed stratifying for Natalizumab (NTZ) treatment in the year before (NO_NTZ vs NTZ group), to account for post-NTZ reactivation.Results
Almost half of patients were NEDA after 2 years, 53.4% in the NO_NTZ group and 36.2% in the NTZ group. Despite an opposite trend during the first 6–12 months, at 2-year follow-up the two groups were comparable for relapses and number of new/enlarging T2 and Gd-enhancing lesions. Baseline parameters of higher disease activity (ARR, Gd enhancing lesions and age at onset) were associated with increased likelihood of failing NEDA criteria or with shorter time to relapse (p < 0.05).Conclusions
Our data strengthen FTY effectiveness in everyday clinical practice, even in patients switching from NTZ treatment. Baseline parameters of inflammatory activity are the most important prognostic factors for mid-term disease reactivation also during second-line treatment with FTY, providing hints on how to select therapies towards a more personalized management.4.
Background
Little is known about the long-term course of disability in relation with disease severity in people with multiple sclerosis (PwMS).Objective
To explore changes in a broad spectrum of disability over 10 years in relation with disease severity in PwMS.Methods
We conducted a longitudinal study of 155 PwMS who attended the MS Centre at Karolinska University Hospital, Stockholm. Disease severity was determined by the use of the Expanded Disability Status Scale (EDSS) and classified as mild MS (EDSS score 0–3.5) or moderate/severe MS (EDSS score 4–9.5). Ten-year changes in perceived physical and psychological impacts of MS, walking, cognition, manual dexterity, participation in social/lifestyle activities, and signs of depression were compared between PwMS with mild and moderate/severe MS at baseline.Results
Although walking, manual dexterity, and cognition declined in both groups, only the moderate/severe group demonstrated that long-term increased physical impact of MS, increased wheel-chair dependency, and reduced participation in social/lifestyle activities. Perceived psychological impact of MS declined in both groups, while signs of depression were experienced by fewer in the mild group and remained unaltered in the moderate/severe group.Conclusion
We found a more pronounced increase in disability across 10 years in individuals with moderate/severe MS compared to mild MS. These findings accentuate the importance of developing a variety of interventions that can be applied across the spectrum of disease severity.5.
Purpose of Review
The proportion to which genetic and environmental factors contribute to the etiology of multiple sclerosis (MS) is still incompletely understood. An interesting association between MS etiology and obesity has recently been shown although the mechanisms underlying this association are still unknown. We propose deregulated gut microbiota and increased leptin levels as possible mechanisms underlying MS etiology in obese individuals.Recent Findings
Alterations in the human gut microbiota and leptin levels have recently been established as immune modulators in both MS patients and obese individuals. A resemblance between pro-inflammatory bacterial profiles in MS and obese individuals was observed. Furthermore, elevated leptin levels push the immune system towards a more pro-inflammatory state and inhibit the regulatory immune response.Summary
Deregulated gut microbiota and elevated leptin levels may explain the increased risk of developing MS in obese individuals. Further research to confirm causality is warranted.6.
Background
Several studies indicated that multiple sclerosis (MS) is frequently associated with other autoimmune diseases. However, it is little known if the coexistence of these conditions may influence the radiologic features of MS, and in particular the brain volumes.Objectives
To evaluate the effect of autoimmune comorbidities on brain atrophy in a large case–control MS population.Methods
A group of MS patients affected by a second autoimmune disorder, and a control MS group without any comorbidity, were recruited. Patients underwent a brain MRI and volumes of whole brain (WB), white matter (WM), and gray matter (GM) with cortical GM were estimated by SIENAX.Results
The sample included 286 MS patients, of which 30 (10.5%) subjects with type 1 diabetes (T1D), 53 (18.5%) with autoimmune thyroiditis (AT) and 4 (0.1%) with celiac disease. Multiple regression analysis found an association between T1D and lower GM (p?=?0.038) and cortical GM (p?=?0.036) volumes, independent from MS clinical features and related to T1D duration (p?<?0.01), while no association was observed with AT and celiac disease.Conclusions
Our data support the importance of considering T1D as possible factors influencing the brain atrophy in MS. Further studies are needed to confirm our data and to clarify the underlying mechanisms.7.

Purpose of Review
Pharmaceutical cannabinoids such as nabiximols, nabilone and dronabinol, and plant-based cannabinoids have been investigated for their therapeutic potential in treating multiple sclerosis (MS) symptoms. This review of reviews aimed to synthesise findings from high quality systematic reviews that examined the safety and effectiveness of cannabinoids in multiple sclerosis. We examined the outcomes of disability and disability progression, pain, spasticity, bladder function, tremor/ataxia, quality of life and adverse effects.Recent Findings
We identified 11 eligible systematic reviews providing data from 32 studies, including 10 moderate to high quality RCTs. Five reviews concluded that there was sufficient evidence that cannabinoids may be effective for symptoms of pain and/or spasticity in MS. Few reviews reported conclusions for other symptoms.Summary
Recent high quality reviews find cannabinoids may have modest effects in MS for pain or spasticity. Future research should include studies with non-cannabinoid comparators; this is an important gap in the evidence.8.
Background
Discrepancies between physicians’ assessment and patients’ subjective representations of the disease severity may influence physician-patient communication and management of a chronic illness, such as multiple sclerosis (MS). For these reasons, it is important to recognize factors that distinguish patients who differently estimate the impact of MS.Purpose
The purpose of this study was to verify if the patients who overestimate or underestimate the impact of MS differ in their perception of personal resources from individuals presenting with a realistic appraisal of their physical condition.Methods
A total of 172 women and 92 men diagnosed with MS completed Multiple Sclerosis Impact Scale, University of Washington Self Efficacy Scale, Rosenberg Self-Esteem Scale, Body Esteem Scale, Brief Illness Perception Questionnaire, Treatment Beliefs Scale, Actually Received Support Scale, and Socioeconomic resources scale. Physician’s assessment of health status was determined with Expanded Disability Status Scale.Results
Linear regression analysis was conducted to identify the subsets of patients with various patterns of subjective health and Expanded Disability Status Scale (EDSS) scores. Patients overestimating the impact of their disease presented with significantly lower levels of self-esteem, self-efficacy in MS, and body esteem; furthermore, they perceived their condition more threatening than did realists and underestimators. They also assessed anti-MS treatment worse, had less socioeconomic resources, and received less support than underestimators. Additionally, underestimators presented with significantly better perception of their disease, self, and body than did realists.Conclusion
Self-assessment of MS-related symptoms is associated with specific perception of personal resources in coping with the disease. These findings may facilitate communication with patients and point to new directions for future research on adaptation to MS.9.

Background
Evidence-based, single-session STI/HIV interventions to reduce sexual risk taking are potentially effective options for implementation in resource-limited settings and may solve problems associated with poor participant retention.Purpose
The purpose of the study is to estimate the efficacy of single-session, behavioral interventions in reducing unprotected sex or increasing condom use.Methods
Data sources were searched through April 2013 producing 67 single-session interventions (52 unique reports; N?=?20,039) that included outcomes on condom use and/or unprotected sex.Results
Overall, participants in single-session interventions reduced sexual risk taking relative to control groups (d + ?=?0.19, 95 % CI?=?0.11, 0.27). Within-group effects of the interventions were larger than the between-groups effects when compared to controls.Conclusions
Brief, targeted single-session sexual risk reduction interventions demonstrate a small but significant effect and should be prioritized.10.

Objective
There is an association between latitude, relative vitamin D deficiency and risk of multiple sclerosis (MS), and an association between vitamin D and disease progression. We have performed a meta-analysis with the aim of investigating the role of therapeutic vitamin D in MS.Methods
A systematic search of databases was performed to identify clinical trials assessing vitamin D in patients with relapsing–remitting MS. Studies were selected based on inclusion and exclusion criteria. Analysis was performed using RevMan 5.3 software.Results
Twelve studies involving 950 patients were included in the final analysis. Studies were divided into four groups because of heterogeneity in study design. Studies were judged to be at low or unclear risk of bias, except in three studies, and this was confirmed by funnel plots. No statistically significant difference was seen for any of the outcome measures. There were non-significant trends in favour of vitamin D for all outcome measures, particularly when only placebo-controlled studies were included. Dose comparison studies showed a significant increase in annualised relapse rate (mean difference 0.15 [95%CI 0.01–0.30]) and non-significant trends of increased Expanded Disability Status Scale and gadolinium-enhancing lesions for the higher-dose arms.Conclusion
These findings suggest that vitamin D supplementation may have a therapeutic role in the treatment of MS. However, there is uncertainty with regard to the most appropriate dose, with high doses potentially being associated with worse outcomes. There remains the need for further well-performed randomised, dose-ranging, placebo-controlled trials of vitamin D in MS.11.

Background
Little national evidence is available on spatial disparities in distributions of parks and green spaces in the USA.Purpose
This study examines ecological associations of spatial access to parks and green spaces with percentages of black, Hispanic, and low-income residents across the urban–rural continuum in the conterminous USA.Methods
Census tract-level park and green space data were linked with data from the 2010 U.S. Census and 2006–2010 American Community Surveys. Linear mixed regression models were performed to examine these associations.Results
Poverty levels were negatively associated with distances to parks and percentages of green spaces in urban/suburban areas while positively associated in rural areas. Percentages of blacks and Hispanics were in general negatively linked to distances to parks and green space coverage along the urban–rural spectrum.Conclusions
Place-based race–ethnicity and poverty are important correlates of spatial access to parks and green spaces, but the associations vary across the urbanization levels.12.

Introduction
Rosette-forming glioneuronal tumors (RGNTs) that do not involve the fourth ventricle are rare. RGNTs were originally thought to be exclusively localized into the fourth ventricle but were found in various anatomical localizations.Material and methods
We review the literature and found 32 cases of this particular RGNT. The outcome was excellent with no mortality reported after surgical treatment. Only two patients had received adjuvant therapy for progression. We added one case of a RGNT located in the cerebellar hemisphere.Case and conclusion
She underwent a subtotal removal with no evidence of progression after. This WHO grade I tumor with a specific biphasic histopathology is of a good oncological outcome after surgical treatment. A long follow-up is needed as recurrence or metastatic progressions exist.13.
Background
Few studies have examined potential disparities in access to transportation infrastructures, an important determinant of population health.Purpose
To examine individual- and area-level disparities in access to the road network, public transportation system, and a public bicycle share program in Montreal, Canada.Methods
Examining associations between sociodemographic variables and access to the road network, public transportation system, and a public bicycle share program, 6,495 adult respondents (mean age, 48.7 years; 59.0 % female) nested in 33 areas were included in a multilevel analysis.Results
Individuals with lower incomes lived significantly closer to public transportation and the bicycle share program. At the area level, the interaction between low-education and low-income neighborhoods showed that these areas were significantly closer to public transportation and the bicycle share program controlling for individual and urbanicity variables.Conclusions
More deprived areas of the Island of Montreal have better access to transportation infrastructure than less-deprived areas.14.

Background
Chronic pain patients increasingly seek treatment through mindfulness meditation.Purpose
This study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults.Method
We conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use.Results
Thirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life.Conclusions
While mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.15.
Introduction
Flavor is known as one of the main criteria that influences food choice. For flavor to be perceived, it needs to be released from the food. Prior studies on mechanisms that govern flavor release have largely focused on interactions with food/ingredients and have analyzed a single flavor modality (aroma or taste). The lack of comprehensive methods has limited our understanding of flavor release from food.Aim
The aim of this study was to comprehensively monitor flavor release by conducting a mass balance analysis (exhaled air, saliva, and gum bolus) of both volatile aroma and non-volatile taste compounds during mastication of chewing gum.Methods
Concentrations of volatiles (ethyl butyrate, benzaldehyde, menthol, menthone, and limonene) and non-volatiles compounds (sorbitol, aspartame, and acesulfame K) were determined over a 12-min mastication time period in expectorated saliva, gum bolus, and exhaled breath (only for volatiles) using LC/MS/MS, GC/MS, and atmospheric pressure chemical ionization-MS.Results
The percent release of the volatile compounds during mastication was lower when compared to the non-volatile compounds. The aroma release profile in the exhaled breath was not related to the compound concentration in the saliva or gum bolus. Results suggested the aroma release was primarily controlled by residual levels of these compounds in the oral cavity and/or the lungs. Similarly, the release profiles of the non-volatiles were not concentration dependent during the first 4 min of mastication, suggesting physical entrapment in the gum base and subsequent release when exposed to the oral cavity for extraction via mechanical stress during mastication.Conclusions
Two main mechanisms of flavor delivery from chewing gum were supported based on a mass balance analysis: (1) the renewal of the gum bolus surface area and (2) the absorption of the aroma compounds in the oral cavity or lungs as an important mechanism of aroma release.Implications
Our findings provide further insight into mechanisms of flavor delivery and an improved basis to investigate flavor perception of foodstuffs.16.

Background
Observational field audits are recommended for public health research to collect data on built environment characteristics. A reliable, standardized alternative to field audits that uses publicly available information could provide the ability to efficiently compare results across different study sites and time.Purpose
This study aimed to assess inter-rater reliability of built environment audits conducted using Google Street View imagery.Methods
In 2011, street segments from St. Louis and Indianapolis were geographically stratified to ensure representation of neighborhoods with different land use and socioeconomic characteristics in both cities. Inter-rater reliability was assessed using observed agreement and the prevalence-adjusted bias-adjusted kappa statistic (PABAK).Results
The mean PABAK for all items was 0.84. Ninety-five percent of the items had substantial (PABAK?≥?0.60) or nearly perfect (PABAK?≥?0.80) agreement.Conclusions
Using Google Street View imagery to audit the built environment is a reliable method for assessing characteristics of the built environment.17.
Purpose of Review
Caring for women with multiple sclerosis (MS), whose first symptoms typically begin during the childbearing years, requires a comprehensive approach to management across a range of reproductive exposures, and beyond through menopause.Recent Findings
This article summarizes what is known about the disease course in women with MS, how it differs from men, and the current state of knowledge regarding effects of reproductive exposures (menarche, childbearing, menopause) on MS-related inflammation and neurodegeneration. Recent findings regarding pregnancy-associated relapses in the treatment era, protective effects of breastfeeding, and care for women during the menopausal transition are reviewed. Then, updated recommendations to guiding women during childbearing—including pre-conception counseling, discontinuation of MS therapies, and management of postpartum relapses—are provided. Whenever possible, areas of uncertainty and avenues for future research are highlighted.Summary
From childhood through the postreproductive life stages, gender and hormonal exposures appear to shape an individual’s risk for MS, as well as the experience of living with MS.18.

Background
Parks are key community assets for physical activity, but some evidence suggests these resources are not equitably distributed.Purpose
This study examined disparities by income and race/ethnicity in the availability, features, and quality of parks across Kansas City, Missouri.Methods
All parks and census tracts (CTs) were mapped using geographical information systems, and park features and quality were determined via audits. Multivariate analyses of covariance analyzed differences in park availability, features, and quality across low-, medium-, and high-income and race/ethnicity CT tertiles.Results
Low-income CTs contained significantly more parks, but also had fewer parks with playgrounds and more quality concerns per park. High minority CTs had more parks with basketball courts, but fewer parks with trails. Medium-income CTs contained more aesthetic features per park.Conclusions
Future research should examine policies that contribute to and that might rectify disparities in park features and quality, especially in low-income and high minority areas.19.

Introduction
Involvement of the peripheral nervous system (PNS) is relatively common in Parkinson’s disease (PD) patients. PNS alterations appear early in the course of the disease and are responsible for some of the non-motor symptoms observed in PD patients. In previous studies, we have shown that environmental toxins can trigger the disease by acting on the enteric nervous system.Material and methods
Here, we analyzed the effect of mitochondrial Complex I inhibition on sympathetic neuritis in vivo and sympathetic neurons in vitro. Combining in vivo imaging and protein expression profiling.Results
we found that rotenone, a widely used mitochondrial Complex I inhibitor decreases the density of sympathetic neurites innervating the gut in vivo, while in vitro, it induces the redistribution of intracellular alpha-synuclein and neurite degeneration. Interestingly, sympathetic neurons are much more resistant to rotenone exposure than mesencephalic dopaminergic neurons.Conclusion
Altogether, these results suggest that enteric sympathetic denervation could be an initial pre-motor alteration in PD progression that could be used as an early biomarker of the disease.20.
