Low serum 25-hydroxyvitamin D levels in migraine are not related to headache frequency: A case-control study in patients with high-frequency/chronic migraine.

Background: Serum 25-hydroxyvitamin D (25[OH]D) concentrations have been shown to be low in patients with migraine, but results are controversial regarding the current role of vitamin D in migraine severity. Using a case-control design, we aimed to evaluate serum 25(OH)D levels in a group of females with high-frequency episodic migraine/chronic migraine (HF/CM) and analyze its association with headache frequency and serum calcitonin gene-related peptide (CGRP) levels.

Methods: Serum 25(OH)D levels were measured in 97 females with HF/CM (age 48.

Headache as main reason for consultation to a hospital Emergency Department in Spain: a prospective study.

Introduction: Headache is common in the general population and a frequent reason for medical consultation.

Objectives: To describe the characteristics of patients attending the Emergency Department (ED) for headache.

Methods: A descriptive study with prospective collection of 100 consecutive patients over 15 years old who attended our ED due to headache as the main complaint.

Real-World Experience with Diroximel Fumarate in Patients with Multiple Sclerosis: A Prospective Multicenter Study.

Background: Current literature and a real-world study suggest that diroximel fumarate (DRF) is safer than dimethyl fumarate (DMF) in the treatment of multiple sclerosis (MS). However, no real-world study to date has significantly addressed the efficacy of this treatment.

Objectives: This study aims to elucidate the safety, tolerability, and efficacy of DRF in a real-world setting, utilizing data from a Spanish national registry of patients commencing DRF therapy post-market introduction.

Clinical characteristics and impact on patient-reported outcomes and quality of life of people with ambulatory secondary progressive multiple sclerosis: DISCOVER study.

Background: People with secondary progressive multiple sclerosis (pwSPMS) experience increasing disability, which impacts negatively on their health-related quality of life (HRQoL). Our aims were to assess the impact of secondary progressive multiple sclerosis (SPMS) on functional status and HRQoL and describe the clinical profile in this population.

Methods: DISCOVER is an observational, cross-sectional, multicenter study with retrospective data collection in real-world clinical practice in Spain.

Unravelling the role of beta-CGRP in inflammatory bowel disease and its potential role in gastrointestinal homeostasis.

Background: The role of beta calcitonin gene-related peptide (beta-CGRP) in gastrointestinal tract is obscure, but experimental models suggest an effect on the homeostasis of the intestinal mucosa. We measured beta-CGRP circulating levels in a large series of subjects with a recent diagnosis of inflammatory bowel disease (IBD), in order to assess the potential role of this neuropeptide in IBD pathogenesis.

Methods: Morning serum beta-CGRP levels were measured by ELISA (CUSABIO, China) in 96 patients recently diagnosed of IBD and compared with those belonging from 50 matched healthy controls (HC) and 50 chronic migraine (CM) patients.

Long-term safety of OnabotulinumtoxinA treatment in chronic migraine patients: a five-year retrospective study.

Background: Real-world studies have shown the sustained therapeutic effect and favourable safety profile of OnabotulinumtoxinA (BoNTA) in the long term and up to 4 years of treatment in chronic migraine (CM). This study aims to assess the safety profile and efficacy of BoNTA in CM after 5 years of treatment in a real-life setting.

Methods: We performed a retrospective chart review of patients with CM in relation to BoNTA treatment for more than 5 years in 19 Spanish headache clinics.

Differences in circulating alpha-calcitonin gene-related peptide levels in inflammatory bowel disease and its relation to migraine comorbidity: A cross-sectional study.

Objective: To analyze the specificity of calcitonin gene-related peptide (CGRP) levels, we measured alpha-CGRP circulating levels in a large series of patients with a recent diagnosis of inflammatory bowel disease (IBD) who were interviewed regarding comorbid headache.

Background: Several studies have found an association between migraine and IBD.

Methods: In this cross-sectional study performed in an IBD clinic, morning serum alpha-CGRP levels were measured by enzyme-linked immunosorbent assay in 96 patients who were recently diagnosed with IBD and compared to those from 50 similar patients with chronic migraine (CM) and 50 healthy controls (HC).

Untangling the mess of CGRP levels as a migraine biomarker: an in-depth literature review and analysis of our experimental experience.

Background: Calcitonin gene-related peptide (CGRP) is the most promising candidate to become the first migraine biomarker. However, literature shows clashing results and suggests a methodological source for such discrepancies. We aimed to investigate some of these methodological factors to evaluate the actual role of CGRP as biomarker.

Progression of subclinical cardiovascular disease in patients with HIV.

Objective: Human immunodeficiency virus (HIV) infected patients are at increased risk of cardiovascular disease (CVD). Multidetector computed tomography (MDCT) stratifies cardiovascular risk in asymptomatic patients with subclinical atherosclerosis. The aim of this study was to determine the ability of MCTD and clinical and laboratory parameters to assess subclinical CVD progression in HIV patients.

CandeSpartan Study: Candesartan Spanish Response-prediction and Tolerability study in migraine.

Introduction: Effectiveness of candesartan in migraine prevention is supported by two randomized controlled trials. We aimed to assess the effectiveness, tolerability, and response predictors of candesartan in the preventive treatment of migraine.

Methods: Observational, multicenter, prospective cohort study.

Metastases Affecting Cranial Nervous Structures in Male Breast Cancer: Two Case Reports.

Introduction: Breast cancer in males is a very rare entity, and survival is mainly influenced by the stage at diagnosis. The lack of early detection tools in men results in a diagnostic delay of about 5-10 years and a higher percentage of metastatic disease at diagnosis. However, the characteristics of head metastases are not well defined.

Increased prevalence of migraine in women with inflammatory bowel disease: A cross-sectional study.

Background: Some studies have suggested an association between migraine and inflammatory bowel disease. We determined migraine prevalence in a cohort of patients with inflammatory bowel disease.

Methods: Patients with inflammatory bowel disease aged 18-65 years were interviewed using an headache questionnaire.

OnabotulinumtoxinA: Discussion of the evidence for effectiveness of OnabotulinumA and its place in chronic migraine treatment.

OnabotulinumtoxinA is a potent inhibitor of muscle contraction that acts by preventing the release of acetylcholine at the neuromuscular junction. In pain states such as migraine, its mechanism of action is not yet fully elucidated and probably relates to the phenomena of central and peripheral sensitization within the trigeminal system. Migraine is a prevalent and disabling disorder and, especially in its variant of chronic migraine (CM), is associated with relevant symptomatic and socioeconomic burden, the objective of preventive treatment being to reduce the frequency, duration, or severity of migraine attacks.

The MIGREX study: Prevalence and risk factors of sexual dysfunction among migraine patients.

Background: Migraine attacks have a high impact on daily activities. There is limited research on the burden of migraine on sexual functioning.

Objective: To determine the prevalence of sexual dysfunction in patients with migraine and its relationship with migraine features and comorbidities.

[Peripheral stimulation of the trigeminal nerve by nasopharyngeal swabbing as a possible trigger of migraine attacks].

Introduction: The role of the central and peripheral nervous system in the generation of migraine is not well understood. Our aim was to determine whether peripheral trigeminal nerve stimuli, such as nasopharyngeal swabs, could trigger migraine attacks.

Subjects And Methods: A survey was sent to 658 doctors, nurses and medical students, asking about the presence of headache suggestive of migraine after carrying out a SARS-CoV-2 swab test, their previous history of migraine, and demographic and headache-related characteristics.
