Responder rates with eptinezumab over 24 weeks in patients with prior preventive migraine treatment failures: post hoc analysis of the DELIVER randomized clinical trial.

Background And Purpose: Eptinezumab reduced monthly migraine days more than placebo in the DELIVER study, a clinical trial with patients with difficult-to-treat migraine and prior preventive treatment failures. This post hoc analysis assesses the sustained response to eptinezumab at the population and patient level and evaluates the potential for response in initial non-responders.

Methods: Adults with chronic or episodic migraine and two to four prior preventive treatment failures were randomized to eptinezumab 100 mg, 300 mg or placebo every 12 weeks.

Numbers needed to treat or harm and likelihood of being helped versus harmed for fremanezumab in patients who had prior inadequate response to two to four classes of migraine preventive medications: A post hoc analysis.

Objective: This study aimed to determine the number needed to treat (NNT), number needed to harm (NNH), and likelihood of being helped or harmed (LHH) in a post hoc analysis of the phase 3b FOCUS trial.

Background: Fremanezumab, a humanized monoclonal antibody that selectively targets calcitonin gene-related peptide (CGRP), has demonstrated efficacy, tolerability, and safety in adults with episodic migraine (EM) or chronic migraine (CM), with documented previous inadequate response to two to four classes of migraine preventive medications.

Methods: In the 12-week double-blind period of the FOCUS study, patients were randomized (1:1:1) to quarterly fremanezumab, monthly fremanezumab, or matched monthly placebo.

Comprehensive Evaluation of Psychotic Features and Their Clinical Correlates in Early Parkinson's Disease.

Objective: The aim was to evaluate the presence of psychotic symptoms using detailed scales and to assess the association with clinical characteristics.

Methods: Healthy controls and patients within three years of PD onset were recruited.

Transorbital sonography in idiopathic intracranial hypertension: Single-center study, systematic review and meta-analysis.

Background And Purpose: Transorbital sonography (TOS) provides a noninvasive tool to detect intracranial pressure by assessing optic nerve sheath diameter (ONSD) and optic disc elevation (ODE). The utility of TOS in the diagnosis of idiopathic intracranial hypertension (IIH) has been increasingly recognized.

Methods: A single-center case-control study sought to compare TOS-acquired ONSD and ODE among IIH-cases versus patients with other neurological diseases (controls).

Clinical significance of small nerve fiber involvement in the early diagnosis and treatment of patients with Fabry disease.

Introduction: Peripheral nervous system is early involved in Fabry disease (FD) and preferentially the small nerve fibers, causing the characteristic neuropathic pain crises usually beginning in childhood. Early detection of this likely underdiagnosed disease is an important approach because causal therapies are available.

Methods: We conducted a case-series study to investigate the small nerve fiber involvement in FD and its contribution to the diagnosis of the disease but also to the timely effective therapy administration.

COVID-19 vaccination-related headache showed two different clusters in the long-term course: a prospective multicenter follow-up study (COVA-Head Study).

Background: Although acute headache following COVID-19 vaccination is widely acknowledged, the long-term progression of these headaches remains poorly understood. Our objective was to identify various phenotypes of prolonged or worsened headaches associated with COVID-19 vaccination and document any changes in these phenotypes over an extended period. Additionally, we aimed to document the diverse headache presentations among patients with pre-existing primary headaches.

microRNA and circRNA in Parkinson's Disease and atypical parkinsonian syndromes.

Multiple System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP) are atypical parkinsonian syndromes (APS) with various clinical phenotypes and considerable clinical overlap with idiopathic Parkinson's disease (iPD). This disease heterogeneity makes ante-mortem diagnosis extremely challenging with up to 24% of patients misdiagnosed. Because diagnosis is predominantly clinical, there is great interest in identifying biomarkers for early diagnosis and differentiation of the different types of parkinsonism.

Arousal deregulation in the co-shaping of neuropsychological dysfunction in frontal and mesial temporal lobe epilepsy.

Objective: Our work aims to investigate the role of physiological arousal in the expression of neuropsychological deficits in frontal lobe epilepsy (FLE) and mesial temporal lobe epilepsy (mTLE), by drawing on the Lurian theory of brain function.

Methods: This is a cross-sectional descriptive observational study performed by quantitative computer-assisted telephone interviews, using a standardized 37-item questionnaire for headaches. The prevalence of medication overuse headache was estimated in the general population and compared within the groups formed by factors such as age, gender, diagnosis of headache type, prophylactic treatment used, geographical regions, social class, workdays lost and loss of productivity.

Association of and polymorphisms with sarcoidosis in a Greek patient cohort.

Introduction: Sarcoidosis is a disease that results from a combination of environmental and genetic factors. Its genetic basis however, is yet to be clarified. The purpose of this study is to determine whether single nucleotide polymorphisms (SNPs) of the B-cell activating factor () and its receptor () are associated with sarcoidosis.

From Karl Wurm and Guy Scadding's staging to F-FDG PET/CT scan phenotyping and far beyond: perspective in the evading history of phenotyping in sarcoidosis.

Sarcoidosis is an inflammatory granulomatous disease of unknown etiology involving any organ or tissue along with any combination of active sites, even the most silent ones clinically. The unpredictable nature of the sites involved in sarcoidosis dictates the highly variable natural history of the disease and the necessity to cluster cases at diagnosis based on clinical and/or imaging common characteristics in an attempt to classify patients based on their more homogeneous phenotypes, possibly with similar clinical behavior, prognosis, outcome, and therefore with therapeutic requirements. In the course of the disease's history, this attempt relates to the availability of a means of detection of the sites involved, from the Karl Wurm and Guy Scadding's chest x-ray staging through the ACCESS, the WASOG Sarcoidosis Organ Assessment Instruments, and the GenPhenReSa study to the F-FDG PET/CT scan phenotyping and far beyond to new technologies and/or the current "omics.

The aims of the study were to investigate the microbiological profile of otitis-prone children in the post-PCV7 era and, to examine the biofilm-forming ability in association with clinical history and outcome during a two-year post-operative follow-up. : In this prospective study, pathogens from patients with COME and RAOM were isolated and studied in vitro for their biofilm-forming ability.

CNS Ageing in Health and Neurodegenerative Disorders.

The process of ageing is characteristic of multicellular organisms associated with late stages of the lifecycle and is manifested through a plethora of phenotypes. Its underlying mechanisms are correlated with age-dependent diseases, especially neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD) and multiple sclerosis (MS) that are accompanied by social and financial difficulties for patients. Over time, people not only become more prone to neurodegeneration but they also lose the ability to trigger pivotal restorative mechanisms.

[The effects of carotid revascularization on mood symptoms and quality of life in patients with high - grade carotid stenosis].

Carotid occlusive disease has been related to ischaemic strokes and cerebral hypoperfusion, thus affecting patients' quality of life, mainly because of cognitive decline and depressive symptoms. Carotid revascularization techniques [carotid endarterectomy (CEA) and carotid artery stenting (CAS)] may, postoperatively, have a positive impact on patients' quality of life and mental condition, though there have been also presented elusive findings and controversial results. The aim of the present study is to evaluate the effect of carotid revascularization (CEA, CAS) on patients' psychological condition and quality of life through a baseline and follow-up examination.

Specific myeloid signatures in peripheral blood differentiate active and rare clinical phenotypes of multiple sclerosis.

Current understanding of Multiple Sclerosis (MS) pathophysiology implicates perturbations in adaptive cellular immune responses, predominantly T cells, in Relapsing-Remitting forms (RRMS). Nevertheless, from a clinical perspective MS is a heterogeneous disease reflecting the heterogeneity of involved biological systems. This complexity requires advanced analysis tools at the single-cell level to discover biomarkers for better patient-group stratification.

Delayed Leucoencephalopathy as a Complication after Endovascular Therapy of Intracranial Aneurysms-A Case Series.

We describe the clinical presentation, radiological findings, treatment and outcomes of three patients with delayed leukoencephalopathy occurring after endovascular treatment (EVT) for cerebral aneurysms-a rare, albeit recurring, complication. The symptoms occurred 6 to 12 months following the EVT of the cerebral aneurysm. Characteristic imaging findings included high-signal changes on T2 images in the white matter without diffusion restriction predominantly at the distribution of the vascular territory of the catheterized arteries, coupled with patchy gadolinium enhancement or low susceptibility weighted imaging (SWI) signals within the white-matter lesions.

Meta-analysis of placebo-arm dropouts in osteoporosis randomized-controlled trials and implications for nocebo-associated discontinuation of anti-osteoporotic drugs in clinical practice.

Unlabelled: Dropout from placebo arms in randomized-controlled trials is a surrogate for nocebo responses, resulting from patients' negative expectations to treatment. Among 16,460 placebo-treated patients in oral anti-osteoporotic drug trials, nocebo dropouts were 8% on average, being higher in older patients. This implies that nocebo may contribute to the osteoporosis treatment gap in clinical practice.
