Examining dietary habits in the context of multiple sclerosis: A comprehensive investigative approach.

AIMS: The aim of this study is to evaluate the nutritional status of patients with multiple sclerosis (MS) and to develop suggestions for changing eating habits in a healthy direction. METHODS: The study was conducted on 171 participants (80.1 % female; 19.9 % male) diagnosed with MS between the ages of 18-60 who applied to Ankara Hacettepe University Hospital Neurology Outpatient Clinic between June 2021 and March 2023. Body weight, height, body composition, waist circumference, upper mid-arm circumference and hand grip strength were measured in accordance with the technique of anthropometric measurements. A three-day food consumption record was taken to evaluate the energy, macro, and micronutrient content of the diet. Mediterranean Diet Assessment Tool was used to assess adherence to diet. RESULTS: Mean age of the participants was recorded as 35.2 ± 10.81 years. According to the body mass index (BMI) classification, 59.9 % of females were in normal limits, while 61.8 % of males were classified as overweight and obese. However, when evaluated in terms of body composition, body fat percentage was found to be above of normal limits in both genders. Also, 70.8 % of participants were sedentary. The percentage of patients who met their daily energy requirements in women with light and moderate activity was higher than in men, but it was not statistically significant. In participants with high activity level, the percentage of patients meeting energy requirements was below 50 % for both genders. Dietary fat and saturated fat intake were higher than the recommendations, while monounsaturated fatty acids and dietary fiber intake were less. The percentages of patients meeting their calcium requirement was below 50 % in both genders. Mean intake amounts of vegetables, fruits, legumes, nuts, and dairy products were below the Türkiye Nutrition Guideline recommendations. CONCLUSION: This study shows the nutritional characteristic of patients with MS in detail with different aspects. Although most of the patients were in normal limits in terms of BMI, body fat percentages were found to be above normal limits in both genders. Total fat and saturated fat intakes were found to be high according to scientific recommendations while the intake of food groups required for a fibre-based diet and intake of dairy products were low.

Gait initiation in multiple sclerosis patients with and without functional loss.

BACKGROUND: Gait initiation (GI) is an important functional task related to balance and gait performance. In addition, it has predictive importance for falls and postural instability in patient with multiple sclerosis (MS). However, it is uncertain how GI is affected in patients in the early stage of MS (Expanded Disability Status Scale (EDSS) ≤3). In this study, it was aimed to investigate the anticipatory postural adjustments (APAs), posterior center of pressure (COPap) displacement, and spatiotemporal variability during GI in patients with and without functional loss in the early stage of MS. METHODS: Forty-four participants (31 MS patients and 13 healthy subjects) involved in this prospective cross-sectional study were divided into three groups: Group-I: Patients without functional loss (EDSS 0 to 1.5) (n = 14), Group-II: Patients with functional loss (EDSS 2 to 3) (n = 17) and Group-III: Healthy subjects (n = 13). Electromyographic activity of the bilateral tibialis anterior (TA) and gastrocnemius medialis (GM) and COPap displacement were recorded during the postural phase of GI. Additionally, spatiotemporal parameters were recorded within the first three steps, and the coefficient of variation was calculated with 40 walks for variability. RESULTS: There were significant differences in the Kruskal-Wallis tests of variables (p<0.05). Group-I demonstrated smaller APAs magnitudes in TA [stance (p = 0.01), swing (p = 0.01)], GM of swing limb (p<0.0001), and smaller COPap displacement (p<0.0001) compared to group-III. Group-II demonstrated smaller APAs magnitudes in all muscles (p<0.0001) compared to group-III and the smallest COPap displacement (p<0.0001). Group-I showed a significant increase in stride width variability compared to group-III (p = 0.01). Group-II showed a significant increase in several variabilities [first stride length (p<0.0001), second stride time (p<0.0001), first double support time (p<0.0001), stride width (p<0.0001)] compared to group-III. CONCLUSION: Patients in the early stage of MS had impairment in both the postural and locomotor phases of GI with more obvious in the patients with functional loss. The results indicate that MS patients without functional loss have difficulty initiating gait. Although there is no functional loss, the patients have a risk of falls, postural instability, and gait impairment due to their inability to initiate gait effectively. As a result, rehabilitation is necessary even if there is no functional loss in patients with MS.

Acute stroke in familial Mediterranean fever: An analysis of 23 new cases and systematic review of the literature.

OBJECTIVE: The nature of neurovascular involvement in cases of familial Mediterranean fever (FMF) has not been adequately clarified. METHODS AND PATIENTS: Clinical features, infarct topography, vascular status, and stroke etiology were prospectively determined in 35 acute neurovascular events that occurred in 23 FMF patients. Clinicoradiological features were compared with an age- and gender-matched control group of 115 acute stroke patients. Characteristics of additional FMF and acute stroke cases (6 episodes in 6 patients) identified from a systematic literature review (PROSPERO registration no: CRD420212264820) were also analyzed. RESULTS: There were 27 acute ischemic stroke episodes in 19 patients, 7 transient ischemic attack episodes in 3 patients, and 1 patient with a single episode of parietal hematoma in our cohort. Twenty (74%) ischemic stroke episodes in 12 patients were cryptogenic. Ten of these 12 cases had a previous FMF diagnosis and were taking colchicine. There was no significant difference in the FMF group in terms of the presence of vascular risk factors and angiography-documented disease in comparison to controls. Cerebral distal artery involvement was significantly prevalent in FMF (78% vs 45%, P = .002). Especially, midbrain central deep perforating territory involvement was higher (30% vs 1%, P < .001). The long-term prognosis (median 8.5 years) under antiplatelet agents and colchicine is favorable. DISCUSSION: The acute stroke phenotype in FMF cases is herein described for the first time. Several clinicoradiological features such as thrombotic lacunar infarcts located in the central mesencephalon seem so typical that we recommend searching for FMF mutations in geographic regions where FMF is common.

Newer disease modifying treatments in pediatric onset multiple sclerosis: Experience from a single center.

BACKGROUND: Disease modifying treatments (DMTs) for multiple sclerosis include injectable drugs (iDMTs) like interferons (IFNs) or glatiramer acetate (GA), and newer agents (nDMTs) in oral and intravenous forms. nDMTs are usually applied in escalation and less frequently as initial treatment in pediatric-onset (POMS). OBJECTIVE: We intended to evaluate the effect of nDMTs in comparison with iDMTs by retrospective examination of our patients with POMS. METHOD: Clinical records of POMS cases who received nDMTs either as escalation or initial treatment and who had at least 12 months' follow-up in our clinic were examined in two groups: patients who were started on iDMTs and later switched to nDMTs (Group A), and those who received nDMTs from the beginning (Group B). Presenting symptoms, annualized relapsing rate (ARR), recent Expanded Disability Status Scale (EDSS), lesion load and presence of contrast enhancing (CE) lesions on magnetic resonance imaging (MRI) were compared. RESULTS: Total 43 patients were included: 33 in Group A and 10 in Group B. Age at onset, female/male ratio, duration since disease onset and duration under nDMT were similar in both groups. Initial involvement was predominantly brainstem and cerebellar in Group A and sensorial, brainstem/cerebellar, and optic nerve in Group B. The most frequently used nDMT was fingolimod in Group A (n = 17, 51.5%) and teriflunomide (n = 6, 60%) in Group B. Median ARR before any treatment was 2 in Group A and 1.5 in Group B (p > 0.05); it decreased to median 1 under iDMTs in Group A and to 0 under nDMTs. Mean follow-up was 6.7 ± 5 years (1-19, median 6 years) in Group A and 3.9 ± 3.7 years (range 1-12, median 2 years) in Group B. At the latest follow-up median EDSS scores were 1 in Group A and 0 in Group B. ARR had increased and lesion load on MRI went up progressively in both groups during follow-up. However, the rate of patients with CE lesions diminished in Group B. CONCLUSION: This single-center study of POMS shows the ARR decreases under any treatment, more markedly under nDMTs, and nDMTs reduce the rate of patients with CE lesions on MRI without a clear effect on lesion load. The ARR tends to increase after the first 2 years of both iDMT and nDMT, suggesting a re-evaluation at that time. The ARR decreases shorty after treatment is changed from an iDMT to a nDMT.

Post-COVID-19 longitudinally extensive transverse myelitis: is it a new entity?

INTRODUCTION: To the best of our knowledge, here we present two post-COVID19 longitudinally extensive transverse myelitis (LETM) with atypical presentations CASE PRESENTATIONS: A 44-year-old male who did not have any previous medical condition and a 73-year-old male foreigner who did not have any disease other than type 2 diabetes mellitus were admitted to our neurology clinic in the same period with similar clinical presentations of transverse myelitis. Upon admission, paraplegia and urinary-fecal incontinence were observed in their neurological examination. Neurological complaints had started within approximately 3-4 weeks following the resolution of the COVID-19 infection. Thoracic lower segment LETM was observed on spinal magnetic resonance imaging (MRI) in one of the patients, and long segment myelitis extending from the lower thoracic segment to the conus medullaris was observed in the other one. No significant diagnostic positivity was present in their diagnostic evaluation. In both cases, we assume a post-infectious etiology in terms of secondary immunogenic overreaction following COVID-19. CONCLUSION: Our patients improved with multiple treatments such as methylprednisolone, intravenous immunoglobulin, and plasmapheresis. Whether post-infectious myelitis behaves differently from other viral infections after COVID-19 is currently unclear. Long lag times appear to be a post-infectious neurological complication resulting from the host response to the virus.

Factors associated with fingolimod rebound: A single center real-life experience.

Background It is still controversial whether the relapse experienced after discontinuation of fingolimod treatment is a rebound. Increasing cases of rebound have been reported in the literature. The rate of fingolimod rebound in patients after fingolimod cessation is reported between 5% and 52%. The present study aims to determine the rate of rebound after discontinuation of fingolimod treatment and the factors affecting the rebound. Methods This retrospective cohort study consists of adult MS patients who have been admitted to the Hacettepe University Hospital Neurology MS Center outpatient clinic between 2012 and 2020. Results During the study period, 642 patients received fingolimod and 23.1% discontinued the fingolimod treatment. Thirteen of 126 patients had a rebound (10.3%) after fingolimod discontinuation. The patients in the rebound group were significantly younger and washout period were significantly longer than those in the non-rebound group. After discontinuation of fingolimod treatment, the EDSS score of the rebound group was significantly higher than the non-rebound group, while Annualized Relapse Rates were similar. Conclusion Younger age, longer washout time, and previous treatment preferences may increase the occurrence probability of rebound. It is recommended that patients should be closely monitored after fingolimod discontinuation and appropriate disease-modifying therapy should be initiated as soon as possible.
