RESUMEN
BACKGROUND: Primary lateral sclerosis (PLS) is an extremely rare condition; therefore, to date no clinical studies have been conducted. The Primary Lateral Sclerosis Functional Rating Scale (PLSFRS) was developed in the United States of America. The PLSFRS is a crucial assessment scale for international collaborative research and future clinical trials for PLS. It is useful for evaluating medical conditions through face-to-face assessments and telephone interviews such as when a face-to-face assessment is not possible due to disasters or the burden of hospital visits. This study assessed the reliability and consistency of in-person and telephone interviews using the Japanese version of the PLSFRS. METHODS: We enrolled 19 Japanese patients who met the specific criteria for inclusion at the six collaborating institutions. The PLSFRS assessments were performed by two evaluators at defined time points and analyzed for intra-rater and inter-rater reliability and consistency between the in-person and telephone interviews. RESULTS: The Japanese version of the PLSFRS was developed by a specialized company and translator, and modified to consider the Japanese lifestyle through a consensus among motor neuron specialists. The quadratic-weighted kappa coefficients for the intra-rater and the inter-rater agreement were substantial (intra-rater: 0.691-1.000, inter-rater: 0.634-1.000). Moreover, the intraclass correlation coefficient for the PLSFRS total score was 0.997 (95% confidence interval, 0.992-0.999). CONCLUSIONS: This study provides results regarding the Japanese version of the PLSFRS intra-rater and inter-rater reliability and consistency between in-person and telephone interviews.

BACKGROUND: Several genetic factors are associated with the pathogenesis of sporadic amyotrophic lateral sclerosis (ALS) and its phenotypes, such as disease progression. Here, in this study, we aimed to identify the genes that affect the survival of patients with sporadic ALS. METHODS: We enrolled 1076 Japanese patients with sporadic ALS with imputed genotype data of 7 908 526 variants. We used Cox proportional hazards regression analysis with an additive model adjusted for sex, age at onset and the first two principal components calculated from genotyped data to conduct a genome-wide association study. We further analysed messenger RNA (mRNA) and phenotype expression in motor neurons derived from induced pluripotent stem cells (iPSC-MNs) of patients with ALS. RESULTS: Three novel loci were significantly associated with the survival of patients with sporadic ALS-FGF1 at 5q31.3 (rs11738209, HR=2.36 (95% CI, 1.77 to 3.15), p=4.85×10-9), THSD7A at 7p21.3 (rs2354952, 1.38 (95% CI, 1.24 to 1.55), p=1.61×10-8) and LRP1 at 12q13.3 (rs60565245, 2.18 (95% CI, 1.66 to 2.86), p=2.35×10-8). FGF1 and THSD7A variants were associated with decreased mRNA expression of each gene in iPSC-MNs and reduced in vitro survival of iPSC-MNs obtained from patients with ALS. The iPSC-MN in vitro survival was reduced when the expression of FGF1 and THSD7A was partially disrupted. The rs60565245 was not associated with LRP1 mRNA expression. CONCLUSIONS: We identified three loci associated with the survival of patients with sporadic ALS, decreased mRNA expression of FGF1 and THSD7A and the viability of iPSC-MNs from patients. The iPSC-MN model reflects the association between patient prognosis and genotype and can contribute to target screening and validation for therapeutic intervention.

A 46-year-old female patient underwent a cord blood transplantation (conditioning regimen: fludarabine/busulfan4/melphalan80; graft-versus-host disease (GVHD) prophylaxis: tacrolimus + mycophenolate mofetil) for acute myeloid leukemia (AML) with her 1st hematological complete response to induction therapy (idarubicin 3 days+cytarabine 7 days). She lost her consciousness due to human herpesvirus 6 (HHV-6) encephalitis on day 31, and therefore, we increased the foscarnet dosage (from 120 mg/kg to 180 mg/kg). Her consciousness level improved after treatment. However, 8 hours of sudden hypothermia occurred with hyperhidrosis, hypertension, and subsequent hyperglycemia on day 34. Her condition did not improve even after administration of anticonvulsant, steroid pulse, or intravenous immunoglobulin. A total of 75 attacks were observed until she was discharged on day 471. She has not shown chronic GVHD or relapsed AML since then. However, HHV-6 caused prolonged damage to her hypothalamus as observed through magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT) using 99mTc ethyl cysteinate dimer even when the virus was not detected from her cerebrospinal fluid. This damage can be responsible for the hypothermia attacks. This is the first case report of prolonged series of hypothermia attacks for over a year as a sequela of HHV-6 encephalitis after a cord blood transplantation for AML.

Lomerizine, calcium channel blocker, is the most used medication for migraine prophylaxis in Japan. The effectiveness of this drug is reported as 50-75%. Telmisartan is angiotensin II receptor blockers which plasma half-life is 24 h. We examined whether telmisartan has preventative benefits in lomerizine non-responsive migraineurs. Lomerizine non-responders received telmisartan (20 mg/day) for 3 months after the investigation period of 3 months. Blood pressure, frequency of headache days/month, headache severity, and doses of triptans and analgesics were analyzed by Wilcoxon signed rank test. Thirty-three migraineurs (25 women and 8 men) participated in this study. Seven patients had migraine with aura and 26 patients had migraine without aura. Mean age (SD) was 46.6 (10.3) years. Mean duration (SD) of migraine was 20.4 (12.5) years. Headache severity exhibited mild degree in 5 patients, moderate degree in 9 patients and severe degree in 19 patients. Mean frequency (SD) of headache days was 10.9 (8.5) days/month. Mean usage (SD) of triptans was 4.8 (5.1) tablets/month and that of analgesics was 15.2 (22.2) tablets/month. Five patients (15%) had hypertension. Telmisartan administration had benefits in 30 patients (90%). This medication significantly decreased frequency of headache days (P < 0.01) and headache severity (P < 0.01). Doses of triptans were reduced at one-third (P < 0.05) and those of analgesia at one-fifth after telmisartan treatment (P < 0.01). After telmisartan, mean (SD) of systolic blood pressure was significantly decreased (P < 0.05). The present study supported that telmisartan treatment had preventive effects in 90% of lomerizine non-responders. Telmisartan non-responders (10%) exhibited chronic migraine and long migraine duration.

BACKGROUND: Antiepileptic drugs (AEDs) may increase development of dyslipidemia and cerebrovascular disease (CVD). We examined the clinical profile and changes of serum lipid levels after AED monotherapy in patients with poststroke epilepsy (PSE) after cerebral infarction (CI). SUBJECTS AND METHODS: Medical records were reviewed in consecutive 2144 CI patients. Monotherapy of valproate, carbamazepine (CBZ), phenytoin (PHT), zonisamide, levetiracetam, or lamotrigine was performed in PSE patients. Serum lipid levels were measured before and at 3 months after AED treatment. RESULTS: The prevalence of PSE was 7.0% in CI patients. The TOAST etiology disclosed large-artery atherosclerosis in 68 patients (45%), cardioembolism in 63 patients (42%), and undetermined cause in 19 patients (13%). CVD risk profile showed obesity of 18 patients (12%), current smoker of 30 patients (20%), hypertension of 75 patients (50%), diabetes mellitus of 32 patients (21%), dyslipidemia of 15 patients (10%), and atrial fibrillation of 63 patients (42%). CBZ or PHT administration increased serum total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C) levels significantly compared to baseline and AED-untreated controls. Those levels were not increased significantly in other AED and control groups. Serum high-density lipoprotein-cholesterol and triglyceride levels did not differ statistically in all groups. CONCLUSIONS: The prevalence of post-CI epilepsy was 7.0%. The pathogenesis contributed to atherothrombosis and cardioembolism. CBZ or PHT administration increased serum TC and LDL-C significantly. Thus, we should pay more attention to serum lipid levels in patients receiving cytochrome P450 (CYP)-induced AEDs, and might considerer switching to non-CYP-induced AEDs in patients with unfavorable serum lipid changes.

A 64-year-old obese man developed hypesthesia in the left arm and leg. Neurological examination revealed decreased senses of pain, touch, and temperature in the left face, arm, trunk, and leg. Remaining functions were normal. Electrocardiogram showed atrial fibrillation. Somatosensory-evoked potentials using the stimulation in the median nerve were normal on both sides. Brain magnetic resonance imaging revealed acute infarction in the right parietal operculum and insula. There were no pathognomonic lesions in the postcentral gyrus, the thalamus, or the brain stem. Cardioembolic operculo-insular infarction was diagnosed. Diffusion tensor tractography map displayed the thalamocortical projections to the primary and the secondary somatosensory cortex (S2). These radiological findings supported that the operculo-insular lesion could disrupt the thalamo-S2 pathway. Thus, the thalamocortical disconnection between the thalamus to the S2 could cause superficial hemisensory dysfunction in the present patient.

UNLABELLED: INTRODUNCTION: We report two patients with optic perineuritis (OPN) and hypertrophic pachymeningitis in Wegener granulomatosis (WG). CASE REPORT: Patient 1: a 74-year-old man developed blurred vision in each eye, sequentially, over a year. In the first episode, visual acuity in the right eye was reduced to no light perception, and in the second episode, the vision in the left eye fell to 20/100. Brain and orbital magnetic resonance imaging (MRI) revealed abnormal enhancement in the meninges and the ipsilateral optic nerve sheath. T2-hyperintense lesions were found along the outer rim of the ipsilateral optic nerve. Seropositive proteinase-3-antineutrophil cytoplasmic antibody (PR3-ANCA), microhematuria and multiple pulmonary nodules suggested the diagnosis of WG. Steroid therapy was initiated 3 months after the first onset, but with no clinical response. At the 2nd episode, rapid administration of steroid ameliorated visual disturbance and MRI lesions markedly. Patient 2: a 72-year-old man developed blurred vision in each eye. Visual acuity measured no light perception in OD and 6/12 in OS. Gadolinium-enhanced MRI disclosed enhancement in the meninges and both optic nerve sheaths. T2-weighted imaging displayed hyperintense lesions along the outer rims of optic nerves. Otolaryngologic examination, seropositive PR3-ANCA and pulmonary nodules supported the diagnosis of WG. Steroid and cyclophosphamide treatment improved visual dysfunction and MRI lesions in the meninges and the optic nerve sheaths. COMMENT: The morphological similarity and the anatomical continuity between the meningeal and the perioptic tissues suggest that extension of granulomatous inflammation along such tissue planes accounted for visual loss in these two patients with WG.

BACKGROUND: Parkinson's disease (PD) shows cardiac sympathetic denervation (SD) in 123I-metaiodobezylguanidine (MIBG) scintigraphy. Recently, SD in the major salivary glands (MSG-SD) was introduced as a possible radiological feature of PD. OBJECTIVE: To identify the clinical characteristics of patients with PD with reduced MSG and cardiac MIBG uptake (dual-SD) compared with those with reduced MSG or cardiac MIBG uptake only (single-SD). METHODS: We recruited 90 patients with PD and 30 controls and evaluated their non-motor (e.g., hyposmia, autonomic dysfunction) and motor (e.g., Movement Disorder Society-Unified Parkinson's Disease Rating Scale) features. We also assessed MIBG uptake in the MSG and heart using a quantitative semi-automatic method, and compared MIBG uptakes between PD and controls. We set cut-off values for optimal sensitivity and specificity, and compared the clinical characteristics of patients with PD between dual- and single-SD groups. RESULTS: MSG and cardiac MIBG uptakes were significantly reduced in PD. Sixty-one patients had dual-SD, 25 had single-SD, and four had non-SD. In patients with PD with normal cardiac SD, 76.5% (13/17) of whom showed abnormalities only in MSG-SD. When clinical characteristics were compared between the dual-SD and single-/non-SD groups, patients in the dual-SD group were older and had more severe hyposmia and autonomic dysfunction, except motor features. Multiple logistic regression analysis identified age as an important confounder. CONCLUSIONS: Patients with PD with dual-SD have more severe non-motor features than other patients. Autonomic dysfunction might progress independently from dopaminergic degeneration. Furthermore, our findings indicate that aging is a crucial factor in PD progression.

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the loss of motor neurons, leading to limb paralysis and respiratory failure. METHODS: C1-C3 cord (1) H-magnetic resonance spectroscopy ((1) H-MRS) was performed in 19 patients with ALS and 20 controls. N-acetylaspartate (NAA), choline-containing compounds, creatine plus phosphocreatine (Cr), and myo-Inositol (m-Ins) were measured. ALS functional rating scale-revised (ALSFRS) and forced vital capacity (FVC) were assessed. The rates of decline were calculated at 6 months before and after (1) H-MRS. RESULTS: NAA/Cr and NAA/m-Ins were decreased significantly, and m-Ins/Cr was increased significantly in ALS patients compared with controls. NAA/Cr and NAA/m-Ins were correlated with ALSFRS and FVC and inversely linked to the decline rates. NAA/Cr, NAA/m-Ins, and m-Ins/Cr were altered markedly in 9 patients with denervation and neurogenic changes in both C2 paraspinal and upper limb muscles. CONCLUSIONS: These metabolite ratios were associated with disease progression and ongoing denervation in neck and hand muscles. C1-C3 cord (1) H-MRS might reflect anterior horn cell damage causing neck/arm weakness and respiratory dysfunction in ALS patients.

BACKGROUND: Multidisciplinary care is recommended for amyotrophic lateral sclerosis (ALS). We opened the first multidisciplinary care "ALS clinic" in Japan in February 2017. This study aimed to clarify the impact of multidisciplinary care on the number and incidence rate of emergency hospitalizations, as well as the survival rate of patients with ALS. METHODS: We studied the medical charts of patients with ALS who visited our hospital between March 1, 2014, and February 29, 2020, in a retrospective study. All patients were divided into two groups: a General Neurology Clinic group (GNC) and an ALS Clinic group (AC), based on the duration of the first visit to our hospital. RESULTS: The survey participants included 90 patients with ALS (32 in the GNC vs 58 in the AC). The mean follow-up duration was 276⯱â¯257â¯days in the GNC and 307⯱â¯267â¯days in the AC. The number of emergency hospitalizations was 11 in the GNC and nine in the AC. The number of patients with two or more emergency hospitalizations was decreased in the AC (3 in the GNC vs 0 in the AC), which was statistically significantly different (pâ¯=â¯0.04). The survival rate was significantly different between the two groups (pâ¯=â¯0.01). CONCLUSIONS: Our results suggest that intervention through ALS multidisciplinary care in the hospital setting effectively controls emergency hospitalizations and improves the survival rate in patients with ALS. Multidisciplinary care is recommended since various medical treatments are required as the condition progresses.

[Objective] Few studies have comprehensively investigated the non-motor symptoms of amyotrophic lateral sclerosis (ALS). We aimed to investigate this aspect of ALS. [Methods] We held a nationwide webinar, titled "ALS Café," and distributed self-report questionnaires to ALS patients. In addition to the frequency of non-motor symptoms such as fatigue, pain, sleep disorders, defecation disorders, sialorrhea, and sexual problems, we evaluated the quality of life (QoL), ALS Functional Rating Scale-Revised (ALSFRS-R), and Patient Health Questionnaire-9 (PHQ-9). [Results] The average age of the 33 respondents (19 male, 14 female) was 60.8 ± 11.2; 96.7% of respondents had some non-motor symptoms. The median ALSFRS-R was 32.0, and seven (21.2%) of the respondents had a PHQ-9 score of 10 or higher. Fatigue was the most common non-motor symptom (81.8%), followed by pain (60.6%), defecation disorders (57.6%), sleep disorders (48.5%), sialorrhea (48.5%), and sexual problems (24.2%). Fatigue was more frequent in females (P = 0.03). Among the non-motor symptoms, pain was the most common factor affecting QoL, followed by fatigue. More than 90% of ALS patients answered that they had never consulted a physician/counselor about sexual problems. Patients with pain had higher PHQ-9 scores than those without (P = 0.01). There was no correlation between the ALSFRS-R score and QoL and PHQ-9. [Conclusions] Most patients with amyotrophic lateral sclerosis had non-motor symptoms, and fatigue and pain were the most common. We showed that many non-motor symptoms affected QoL without correlating with ALSFRS-R score. Attention should be paid to those even if the motor symptoms of ALS are mild.

INTRODUCTION: Branch atheromatous disease (BAD) is a type of cerebral infarction caused by stenosis or occlusion at the entrance of the penetrating branch due to the presence of plaque. Despite its clinical significance, it is not clear how these plaques are formed. Focal geometrical characteristics are expected to be as important as vascular risk factors in the development of atherosclerosis. This study aimed to analyze the association between middle cerebral artery (MCA) geometric features and the onset of BAD. Shear stress results from the blood flow exerting force on the inner wall of the vessels and places with low wall shear stress may be prone to atherosclerosis. At the curvature of blood vessels, the shear stress is weak on the inside of the curve and plaque is likely to form. When this is applied to the MCA M1 segment, downward type M1 is likely to form plaques on the superior side. Because the lenticulostriate artery usually branches off from the superior side of the MCA M1 segment, in downward type M1, a plaque is likely to be formed at the entrance of the penetrating branch, and for that reason, BAD is likely to onset. METHODS: We retrospectively reviewed hospitalized stroke patients with BAD and investigated the morphology of their MCA using magnetic resonance imaging. The M1 segment was classified as straight or curved. Additionally, we compared the difference between the symptomatic and the asymptomatic side. Data regarding patients' medical history were also collected. RESULTS: A total of 56 patients with lenticulostriate artery infarctions and BAD were analyzed. On the symptomatic side, downward type M1 accounted for the largest proportion at 44%, whereas on the asymptomatic side, it was the lowest, at 16%. CONCLUSION: A downward type MCA may be associated with the onset of BAD and the morphological characteristics might affect the site of plaque formation. J. Med. Invest. 70 : 411-414, August, 2023.

OBJECTIVES: To analyze 123I-metaiodobenzylguanidine (MIBG) uptake in the parotid and submandibular glands in patients with Parkinson's disease (PD) in comparison with controls, and to compare MIBG uptake between those glands and the myocardium. Furthermore, we aimed to identify the relationships between clinical features and MIBG uptake. METHODS: We recruited 77 patients with PD and 21 age-matched controls. We assessed MIBG scintigraphy in the major salivary glands and myocardium. We calculated the MIBG uptake ratio in the parotid glands/mediastinum (P/M), submandibular glands/mediastinum (S/M), and heart/mediastinum (H/M) using a quantitative semi-automatic method. We investigated the correlations between MIBG uptake and clinical features. RESULTS: The P/M and H/M ratios in the early and delayed phases were significantly reduced in PD patients compared to controls, while the delayed phase S/M ratio was reduced in PD patients compared to controls. The P/M ratio correlated with the S/M ratio, while neither the P/M nor S/M ratio correlated with the H/M ratio. Between PD patients and controls, sensitivity and specificity were 54.8% and 59.1% for the delayed phase P/M ratio, while sensitivity and specificity were 59.5% and 61.0% for the delayed phase S/M ratio, respectively. Furthermore, sensitivity and specificity for the delayed phase H/M ratio were 85.7% and 79.2, respectively. CONCLUSION: MIBG uptake in the parotid and submandibular glands was reduced in patients with PD. Furthermore, sympathetic denervation in the major salivary glands and myocardium might progress independently. Our findings suggest a new aspect of the pathological distribution of PD.

Disaster preparation is an important issue for patients with amyotrophic lateral sclerosis (ALS). However, to the best of our knowledge, no studies have investigated disaster preparedness among patients with ALS. In this study, we aimed to investigate disaster preparation in patients with ALS and their caregivers, including their families, in Japan. We conducted a nationwide webinar in September 2022 titled "ALS Café" and distributed a self-report questionnaire to participants with questions about awareness of disaster preparedness, social countermeasures, stockpiles, and electricity demand. Forty-eight patients with ALS (27 male; average age 60.0 ± 9.3 years) and 23 caregivers (8 male; 55.7 ± 9.9 years) responded. The median revised ALS Functional Rating Scale score was 30.5, and 25% of the patients with ALS were on a ventilator. More than 70% of the respondents answered that they were not prepared for disasters, increasing to 89% in patients not using ventilators. In the event of their phones being down, 86% of the respondents had no plans for alternative means of communication. <30% of the respondents, including ventilator users, had secured human resources for transportation. Twenty-five percent of the respondents did not stockpile food and beverages, and 12% of the ventilator users had no government-recommended ventilator preparation equipment. Thus, although patients with ALS and their families with ventilators have a high awareness of disaster preparedness, their awareness remains insufficient. Furthermore, patients with ALS and their families without ventilators have a low awareness of disaster preparedness. Therefore, better education regarding disaster preparedness is necessary for these groups.

The prevalence and implications of vertebrobasilar dolichoectasia (VBD), a causative arteriopathy of stroke are unclear in Asian stroke patients. Through a comparative study of VBD and non-VBD stroke patients, we aimed to elucidate the clinicoradiologic features of VBD patients in Japan. A total of 481 consecutive patients (302 men and 179 women) with acute stroke were admitted to our department between 2007 and 2008. Of these 481 inpatients, 374 (231 men and 143 women) had brain infarct (BI), and 107 (71 men and 36 women) had brain hemorrhage (BH). We reviewed medical records, and VBD was diagnosed by magnetic resonance angiography. Cardiovascular disease (CVD) risk profile, modified Rankin scale score at 30 days poststroke, and stroke lesions were compared among 4 groups: the VBD BI group, the VBD BH group, the non-VBD BI group, and the non-VBD BH group. The diameter, height, and lateral displacement of the basilar artery (BA) were analyzed in the VBD patients. Statistical analyses used multivariate logistic regression analysis. VBD was found in 37 patients (34 men and 3 women). Mean age (± SD) was 64.4 ± 14.7 years (63.4 ± 14.6 years in men and 65.3 ± 6.1 years in women). Twenty-four patients (21 men and 3 women) had BI, and 13 men had BH. There were significant male preferences in VBD BI (P < .01) and VBD BH patients (P < .01). Mean age (± SD) was 67.7 ± 14.3 years in BI patients and 56.7 ± 12.7 years in BH patients. The VBD BH men were significantly younger than the non-VBD BH men (P < .05) and VBD BI men (P < .01). Frequency of current smoking was significantly greater in VBD BI patients compared with non-VBD BI patients (P < .05). Other CVD risk factors did not differ among the 4 groups. Mean modified Rankin Scale score was significantly higher in VBD BH men compared with non-VBD BH men and VBD BI men (P < .01). The height and lateral displacement of the BA were scored more severely in BH patients than in BI patients (P < .01), but BA diameter did not differ between BH and BI patients. The frequency of pontine infarct and hemorrhage was 3-fold greater in VBD BI (P < .05) and VBD BH patients (P < .005) compared with non-VBD BI and BH patients. Our findings indicate a VBD prevalence of 7.7% in stroke patients, 6.4% in BI patients, and 12.1% in BH patients. Our clinicoradiologic analyses suggest male predominance, younger onset of BH, and higher frequency of pontine lesions in VBD patients. Significant BA changes and poor outcome of stroke were found in patients with hemorrhagic VBD rather than ischemic VBD. Thus, more attention should be paid to risk and care of BH in VBD patients, in addition to those of BI.

OBJECTIVE: To assess the needs of patients with amyotrophic lateral sclerosis (ALS) and their families when being communicated the diagnosis. METHODS: We held a nationwide webinar in September 2020, titled "ALS Café", and distributed a self-report questionnaire to participants. PATIENTS: This cross-sectional study included 56 respondents (patients, n = 32; family members, n = 24). RESULTS: Of the 56 respondents, 47 (84%) reported being anxious when they were communicated their diagnosis. The average time allocated for communicating the diagnosis was 36.3 ± 25.6 min, and 30% of respondents believed that insufficient time was allocated. Nearly half of the respondents were communicated their diagnosis by one physician, and 57% of the respondents received their diagnosis in one session. Approximately 80% of respondents received information about ventilators when they were being communicated their diagnosis, but most patients did not want to receive this information at that time. The anxious group tended to answer that the time to communicate the diagnosis was short. Meanwhile, all respondents in the mildly anxious group were provided with one or more information about the supportive contents along with the diagnosis. Moreover, in Japan, many patients with ALS and their families desire the legalization of euthanasia, which might affect decision-making. CONCLUSIONS: This study shows that a longer amount of time spent communicating the diagnosis and provision of descriptions needed by patients and their families are important. This can help clinicians understand what the patient requires while being communicated their diagnosis.

Objective To assess the long-term effects of hybrid assistive limb (HAL) treatment on gait in patients with amyotrophic lateral sclerosis (ALS). Methods Three courses of treatment with HAL were administered to three women with ALS. Each course had a four- to five-week duration, during which the treatment was performed nine times, with a rest period of at least two months between each course. Gait ability (2-minutes-walk and 10-m-walk tests), ALS Functional Rating Scale-Revised, and respiratory function tests were performed before and after each treatment course. Patients Patients diagnosed with ALS, according to the updated Awaji criteria, by board-certified neurologists in the Department of Neurology and Department of Rehabilitation Medicine, Toho University Omori Faculty of Medicine between January and December 2019 were recruited. Results The average time from the start to the end of the 3 courses was 319.7±33.7 days. A multiple regression analysis was performed for the 2-minutes-walk and 10-m-walk tests, using the baseline value, each participant's ID, and time point as covariates. Changes after each course were considered outcomes. Following the 3 treatment courses, the 2-minutes walk distance improved by 16.61 m (95% confidence interval, -9.33-42.54) compared with the baseline value, but this improvement was not statistically significant (p=0.21). However, cadence significantly improved by 1.30 steps (95% confidence interval, 0.17-2.42; p=0.02). Conclusion Long-term, repetitive HAL treatments may help patients with ALS maintain their gait.

OBJECTIVE: The Hybrid Assistive Limb (HAL; CYBERDYNE, Inc., Japan) is a wearable robot device that provides effective gait assistance according to voluntary intention by detecting weak bioelectrical signals of neuromuscular activity on the surface of the skin. We used HAL for patients with amyotrophic lateral sclerosis (ALS) to determine whether HAL training had an effect on their gait ability. METHODS: We conducted a single-center, single-arm, observational study. Patients with ALS underwent HAL training once per day (20-40 min per session) for 9-10 days for at least 4 weeks. Gait ability was evaluated using the 2-minute walk test, the 10-meter walk test without the assistance of HAL, and activities of daily living (ADL) using the Barthel Index and Functional Independence Measures before and after a full course of HAL training. RESULTS: There were no dropouts or adverse events during the observation period. Gait function improved after HAL training. The 2-minute walk test revealed a mean gait distance of 73.87 m (36.65) at baseline and 89.9m (36.70) after HAL training (p = 0.004). The 10-meter walk test showed significantly improved cadence, although gait speed, step length on the 10-m walk, or ADL measurements did not change significantly. CONCLUSIONS: Although HAL is not a curative treatment for ALS, our data suggest that HAL may be effective in ameliorating and preserving gait ability in patients with ALS.

BACKGROUND: Migraine is associated with an increased risk for ischemic stroke and cardiovascular disease (CVD). Recent studies have suggested vascular dysfunction in the aorta, the brachial and femoral artery. Little is known about such arterial changes in Japanese midlife migraineurs. We aimed to evaluate arterial pulse wave velocity (PWV) and ankle-brachial index (ABI) in middle-aged migraineurs at low CVD risk. METHODS: Brachial-ankle PWV (baPWV) and ABI, using an oscillometric technique, were measured in 111 migraineurs (81 women and 30 men) and 110 controls. All participants had no CVD risk factors. Statistical comparison of baPWV and ABI between both groups and the relationship to clinical variables of migraineurs were analyzed. RESULTS: Twenty-two subjects had migraine with aura and 89 had migraine without aura. Mean age (SD) of migraineurs was 44.4 (8.4) years. Mean duration (SD) was 18.0 (10.8) years. Attack frequency was 60 subjects in ≥1 time/month and 51 subjects in <1 time/month. Mean score (SD) of Headache Impact Test-6 (HIT-6) was 61.4 (8.7). CVD risk profile did not differ statistically between migraineurs and controls. Mean baPWV (SD) of migraineurs was 1247 (189) cm/second in women and 1356 (126) in men. That of controls was 1138 (136) in women and 1250 (121) in men. baPWV was increased significantly in female and male migraineurs. Mean ABI (SD) was 1.05 (0.06; 1.04 [0.07] in men and 1.05 [0.06] in women) in migraineurs and 1.06 (0.07) in controls (1.05 [0.08] in men and 1.06 [0.08] in women). ABI did not differ statistically between migraineurs and controls. Migraine subtypes, duration, attack frequency, and HIT-6 score were not associated with baPWV and ABI. CONCLUSION: The present study indicated higher baPWV in midlife migraineurs without CVD risk factors. This pathogenesis could reflect distinct vascular reactivity rather than arterial stiffness due to atherosclerosis.

BACKGROUND: Oxidative stress plays a role in the pathogenesis of neuronal death. Serum levels of urate or lipid were associated with the incidence of Parkinson's disease (PD). OBJECTIVE: We compared urate, paraoxonase-1 (PON1), iron, ferritin and lipid in sera of 119 PD patients and 120 healthy controls matched by age, sex and body mass index. We aimed to elucidate whether those serological data are correlated with disease progression. RESULTS: Mean age (SD) of PD patients was 73.4 (8.7) years. Mean Yahr stage (SD) was 3.2 (0.9). Mean disease duration (SD) was 6.9 (5.1) years. Mean dose of L-DOPA (SD) was 355 (157) mg/day. As compared to controls, serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), urate and PON1 activity were significantly reduced, and serum ferritin levels were significantly increased in male and female PD patients. Serum urate levels and PON1 activities were inversely related, and serum ferritin levels were correlated with Yahr stage and PD duration in men and women. Serum levels of TC and LDL-C were inversely related to Yahr stage or PD duration in female patients. CONCLUSIONS: Our studies indicated serological profiles of urate, PON1, ferritin, TC and LDL-C in PD patients. These serological changes were linked to PD progression. Metabolism of lipid, oxidant- and antioxidant-related substances may contribute to the pathogenesis and the progression of PD.
