Ethical Use of Cadaveric Images in Anatomical Textbooks, Atlases, and Journals: A Consensus Response From Authors and Editors.

Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose.

The Impact of Migraine on the Whole Life Course of Patients: Results from the OVERCOME (Japan) 2nd Study.

Introduction: The impact of migraine on patients' lives, including challenges they face before getting access to appropriate medical management, is not well understood. The ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE [OVERCOME (Japan)] 2nd study was conducted to provide information regarding burden and experience with migraine throughout the life course.

Methods: This cross-sectional, population-based, nationwide online survey was conducted in adults with or without migraine.

Migraine Management in Japan: Current Approaches and Science Narrative Including an Evidence-based Review.

Migraine is a prevalent and highly disabling neurological disorder. Recent progress in neuroscientific research has contributed to the development of new therapies for migraine, including triptans, ditans, calcitonin gene-related peptide (CGRP) antagonists, and CGRP-related monoclonal antibodies. Noninvasive neuromodulation devices have also been developed.

A Discrete-Choice Experiment Assessing the Patient Preferences and Real-World Experiences of Patients with Migraine in Japan.

Introduction: Migraine is a debilitating headache disorder with a high prevalence in Japan that imposes significant societal burden. Although the Japanese Clinical Practice Guideline for Headache Disorders 2021 recommends both acute and preventive migraine treatments, the usage of preventive treatments is still limited. Therefore, it is crucial to understand the treatment preferences of patients with migraine pertaining to both acute and preventive treatments.

Efficacy of galcanezumab in migraine central sensitization.

Galcanezumab, a monoclonal antibody targeting the calcitonin gene-related peptide pathway (CGRP mAb), acts peripherally due to its large size. However, recent studies have suggested that CGRP mAbs may also have a central mode of action. This study aimed to evaluate the central effects of galcanezumab on migraine central sensitization.

Novel and reappraised wide-band EEG findings in migraineurs: Its correlation with several clinical variables.

Objective: Cortical spreading depolarization is one possible pathogenesis of migraine, of which slow neurophysiological change is barely recorded in conventional EEG settings. Using wide-band EEG conditions, we reappraised the features of EEG in migraineurs, including subdelta-band EEG changes.

Methods: This retrospective study included 144 patients with migraine.

Preliminary External Validation Results of the Artificial Intelligence-Based Headache Diagnostic Model: A Multicenter Prospective Observational Study.

The misdiagnosis of headache disorders is a serious issue, and AI-based headache model diagnoses with external validation are scarce. We previously developed an artificial intelligence (AI)-based headache diagnosis model using a database of 4000 patients' questionnaires in a headache-specializing clinic and herein performed external validation prospectively. The validation cohort of 59 headache patients was prospectively collected from August 2023 to February 2024 at our or collaborating multicenter institutions.

Effectiveness of fremanezumab treatment in patients with migraine headache.

Objective: To evaluate the efficacy and safety of fremanezumab for migraine prevention.

Design: Retrospective, single-center, real-world study.

Setting: Regional tertiary headache center in Japan.

[Epileptic seizure and migraine attack: A revisit from the "Borderland of Epilepsy" to clinical implementation of infraslow activity/DC shifts in scalp EEG].

Migraine attacks, especially ones with aura, have symptoms similar to epileptic seizures, and the two may sometimes be difficult to differentiate clinically. However, the characteristic minute-by-minute symptom development and progress within 60 ‍min is useful for diagnosis. Although the details of its pathophysiology remain unsolved, cortical spreading depolarization (CSD) is one of the main pathogenetic factors.

A study to investigate the prevalence of headache disorders and migraine conducted using medical claims data and linked results from online surveys: post-hoc analysis of other headache disorders.

Background: Surveys using questionnaires to collect epidemiologic data may be subject to misclassification. Here, we analyzed a headache questionnaire to evaluate which questions led to a classification other than migraine.

Methods: Anonymized surveys coupled with medical claims data from individuals 19-74 years old were obtained from DeSC Healthcare Inc.

Cost Effectiveness of Fremanezumab in Episodic and Chronic Migraine Patients from a Japanese Healthcare Perspective.

Background And Objectives: Fremanezumab is an effective treatment for episodic (EM) and chronic migraine (CM) patients in Japan, but its cost effectiveness remains unknown. The objective of this study was to determine the cost effectiveness of fremanezumab compared with standard of care (SOC) in previously treated EM and CM patients from a Japanese healthcare perspective.

Methods: Estimated regression models were implemented in a probabilistic Markov model to inform effectiveness and health-related quality-of-life data for fremanezumab and SOC.

Clinical Evaluation After Discontinuation of Galcanezumab in Japanese Patients with Episodic and Chronic Migraine: Analysis of a Randomized, Placebo-Controlled Trial and Open-label Extension Study.

Introduction: This analysis of two Japanese clinical trials evaluated efficacy and safety after galcanezumab (GMB) discontinuation in patients with episodic migraine (EM) and chronic migraine (CM).

Methods: Data were from a 6-month, randomized, double-blind, placebo [PBO]-controlled primary trial (patients with EM) and a 12-month open-label extension trial (patients with EM/CM). Patients received 6 months' (primary) or 12/18 months' (extension) treatment with GMB 120 mg (GMB120) plus 240-mg loading dose or 240 mg (GMB240) with 4 months' post-treatment follow-up.

Long-term treatment with lasmiditan in patients with migraine: post hoc analysis of treatment patterns and outcomes from the open-label extension of the CENTURION randomized trial.

Background: The objective of this analysis was to gain new insights into the patient characteristics and other factors associated with lasmiditan usage and clinical outcomes under conditions resembling the real-world setting.

Methods: This was a post hoc analysis of data from the 12-month, open-label extension (OLE) of the phase 3, double-blind, randomized, controlled CENTURION trial, which examined the efficacy and safety of lasmiditan as acute treatment across four migraine attacks. Patients completing the main study who treated ≥ 3 attacks could continue in the OLE.

CGRP-monoclonal antibodies in Japan: insights from an online survey of physician members of the Japanese headache society.

Background: Anti-calcitonin gene-related peptide monoclonal antibodies (CGRPmAbs) have greatly changed migraine treatment options. In Japan, although CGRPmAb guidelines (≥ 4 monthly migraine days (MMDs) and ≥ 1 previous preventive failure) are well-acknowledged, the actual use of CGRPmAbs and the circumstances of the related headache care are unknown.

Methods: We conducted an online survey of Japanese Headache Society members, inquiring about the physicians' experience with CGRPmAbs and how they make decisions related to their use.

Cerebral Arteriovenous Malformation With Ipsilateral Middle Cerebral Artery Occlusion: A Case Report.

We report the case of a 29-year-old man who presented with a sudden headache. Computed tomography showed a small intraventricular hemorrhage in the left lateral ventricle. Cerebral angiograms suggested rupture of a coexisting feeder aneurysm in the left temporal cerebral arteriovenous malformation (AVM).

Effect of istradefylline on postural abnormalities in patients with Parkinson's disease: An association study of baseline postural angle measurements with changes in Unified Dystonia Rating Scale total score.

In our previous study, istradefylline treatment in patients with Parkinson's disease (PD) improved postural abnormalities (PAs), as seen from a decrease in the mean Unified Dystonia Rating Scale (UDRS) total score from week 0 to week 24. A subgroup analysis based on baseline clinical characteristics investigated the association between improvement in the UDRS total score and istradefylline treatment. However, the association between an objective assessment of PAs and improvement in the UDRS total score is unclear.

The World Health Organization Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders and the headache revolution: from headache burden to a global action plan for headache disorders.

The World Health Organization (WHO) Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders was developed by WHO to address the worldwide challenges and gaps in provision of care and services for people with epilepsy and other neurological disorders and to ensure a comprehensive, coordinated response across sectors to the burden of neurologic diseases and to promote brain health across life-course. Headache disorders constitute the second most burdensome of all neurological diseases after stroke, but the first if young and midlife adults are taken into account. Despite the availability of a range of treatments, disability associated with headache disorders, and with migraine, remains very high.

Impact of Migraine on Daily Life: Results of the Observational survey of the Epidemiology, Treatment, and Care of Migraine (OVERCOME [Japan]) Study.

Introduction: The impacts of migraine on daily life, including daily activities and fundamental health indicators (sleep and mental health), have not been described in detail for people with migraine in Japan.

Methods: The cross-sectional ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE (OVERCOME [Japan]) study was conducted between July and September 2020. Impacts of migraine on housework, family/social/leisure activities, driving, and sleep were assessed using questions from the Migraine Disability Assessment (MIDAS), Migraine-Specific Quality-of-Life Questionnaire, and Impact of Migraine on Partners and Adolescent Children scales and questions developed for OVERCOME (Japan).

[Impact of migraine on family members: an investigation by Impact of Migraine on Partners and Adolescent Children (IMPAC)].

Using the Japanese version of the Impact of Migraine on Partners and Adolescent Children (IMPAC) and Family Question prepared based on IMPAC, we investigated the impact of migraine on family members from the perspectives of both patients and their family members. Our results showed that migraine had an impact on the family members living with the patients in Japan as well, and the perception of migraine differed partially between patients and their family members. We also found that the Japanese version of the IMPAC showed a correlation with existing instruments to evaluate impact of migraine, indicating its validity.

Japan Trevo Registry: Real-world Registry of Stent Retriever Alone or in Combined Therapy with Aspiration Catheter for Acute Ischemic Stroke in Japan.

Endovascular therapy (EVT) for real-world patients after extended time frames is associated with concerns about its efficacy and safety. We conducted a prospective registry at 77 centers between November 2019 and October 2020. The registry criteria included patients treated with Trevo Retriever alone or in combined therapy with an aspiration catheter.

Small vessel platelet thrombosis in the peripheral nerves in POEMS syndrome.

Introduction/aims: Vascular thrombosis is prevalent among patients with polyneuropathy, organomegaly, endocrinopathy M-protein, and skin changes (POEMS) syndrome. The endothelial cells in the endoneurium are often hypertrophied and the lumen is frequently occluded. Consequent local hypoxia may increase vascular endothelial growth factor (VEGF), which induces hypercoagulation and vascular permeability.
