What is the Optimal Management of Metastatic Spine Patients With Intermediate Spinal Instability Neoplastic Scores: To Operate or Not to Operate?

Study Design: Systematic review.

Objective: In patients with extradural metastatic spine disease, we sought to systematically review the outcomes and complications of patients with intermediate Spinal Instability Neoplastic Score (SINS) lesions undergoing radiation therapy, percutaneous interventions, minimally invasive surgeries, or open spinal surgeries.

Methods: Following PRISMA guidelines for systematic reviews, MEDLINE, EMBASE, Web of Science, the Cochrane Database of Systematic Reviews and the Cochrane Center Register of Controlled Trials were queried for studies that reported on SINS intermediate patients who underwent: 1) radiotherapy, 2) percutaneous intervention, 3) minimally invasive, or 4) open surgery.

Prevalence of restless legs and association with patient-reported outcome measures in myasthenia gravis.

Study Objectives: Inflammatory and immune mechanisms are considered in restless legs syndrome (RLS) pathophysiology with several autoimmune diseases associated with RLS. There is a paucity of studies examining RLS prevalence in myasthenia gravis (MG), an autoimmune neuromuscular disease. This study investigated RLS prevalence and association with patient-reported measures in a large registry of participants with MG using a validated RLS diagnostic questionnaire.

Education and Training in Global Neurosurgery: Current State and Path Toward a Uniform Curriculum.

Education is a sustainable long-term measure to address the global burden of neurosurgical disease. Neurosurgery residencies in high-income countries are accredited by a regional governing body and incorporate various educational activities. Few opportunities for training may be present in low-income and middle-income countries due to a lack of neurosurgery residency programs, tuition, and health care workforce reductions.

Factors That Influence Health Care-Seeking Behavior and Health Information Disclosure Among U.S. Air Force Pilots.

Introduction: The reality of pilot health care avoidance behavior is often common knowledge to both pilots and aeromedical physicians, but the underlying factors leading to this behavior are less understood. In the current study, we conducted a qualitative assessment of a sample of U.S.

The Gut-Brain Axis in Parkinson's Disease.

Parkinson's disease (PD) involves both the central nervous system (CNS) and enteric nervous system (ENS), and their interaction is important for understanding both the clinical manifestations of the disease and the underlying disease pathophysiology. Although the neuroanatomical distribution of pathology strongly suggests that the ENS is involved in disease pathophysiology, there are significant gaps in knowledge about the underlying mechanisms. In this article, we review the clinical presentation and management of gastrointestinal dysfunction in PD.

History of ALS and the competing theories on pathogenesis: IFCN handbook chapter.

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative disorder of the human motor system, first described in the 19th Century. The etiology of ALS appears to be multifactorial, with a complex interaction of genetic, epigenetic, and environmental factors underlying the onset of disease. Importantly, there are no known naturally occurring animal models, and transgenic mouse models fail to faithfully reproduce ALS as it manifests in patients.

Dissociation of Centrally and Peripherally Induced Transcranial Magnetic Stimulation Effects in Nonhuman Primates.

Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation method that is rapidly growing in popularity for studying causal brain-behavior relationships. However, its dose-dependent centrally induced neural mechanisms and peripherally induced sensory costimulation effects remain debated. Understanding how TMS stimulation parameters affect brain responses is vital for the rational design of TMS protocols.

Effect of chronic antiplatelet therapy on clinical outcomes of endovascular thrombectomy for treatment of acute ischemic stroke.

Objective: The objective of this study was to investigate the prognostic significance of chronic antiplatelet therapy (APT) usage in acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT). Long-term APT may enhance recanalization but may also predispose patients to an increased risk of hemorrhagic transformation.

Methods: Weighted hospitalizations for anterior-circulation AIS treated with EVT were identified in a large United States claims-based registry.

Predictors of congruency between clinical and radiographic Oxfordshire Community Stroke Project Classification subtypes.

Background: The Oxfordshire Community Stroke Project (OCSP) classification has been widely used to assess ischemic stroke patients based on clinical characteristics alone. However, the correlation between the clinical presentation evaluated using OCSP and imaging findings is yet to be determined. Our study aimed to describe the baseline characteristics of the OCSP subtypes of patients admitted with ischemic stroke and evaluate the predictors of the relationship between clinical and neuroimaging findings.

Design and Statistical Innovations in a Platform Trial for Amyotrophic Lateral Sclerosis.

Platform trials allow efficient evaluation of multiple interventions for a specific disease. The HEALEY ALS Platform Trial is testing multiple investigational products in parallel and sequentially in persons with amyotrophic lateral sclerosis (ALS) with the goal of rapidly identifying novel treatments to slow disease progression. Platform trials have considerable operational and statistical efficiencies compared with typical randomized controlled trials due to their use of shared infrastructure and shared control data.

Assessment of the External Validity of Dialogue Support for Predicting Lumbar Spine Surgery Outcomes in a US Cohort.

Study Design: External validation using prospectively collected data.

Objectives: To determine the model performance of "Dialogue Support" (DS) in predicting outcomes after lumbar spine surgery.

Summary Of Background Data: To help clinicians discuss risk versus benefit with patients considering lumbar fusion surgery, DS has been made available online.

Combined Endoscopic Endonasal and Transpalatal Repair of Congenital Anterior Cranial Fossa Agenesis.

Background: Congenital basal meningoceles and encephaloceles are rare pathologies that may present in isolation or with characteristic-associated clinical features. Rarely, children with congenital midline defects may present with massive encephaloceles secondary to anterior cranial fossa agenesis. Traditionally, transcranial approaches with frontal craniotomies were used to reduce the herniated contents and repair the skull base defect.

Reduced-order modeling and analysis of dynamic cerebral autoregulation via diffusion maps.

A data-driven technique for parsimonious modeling and analysis of dynamic cerebral autoregulation (DCA) is developed based on the concept of diffusion maps. Specifically, first, a state-space description of DCA dynamics is considered based on arterial blood pressure, cerebral blood flow velocity, and their time derivatives. Next, an eigenvalue analysis of the Markov matrix of a random walk on a graph over the dataset domain yields a low-dimensional representation of the intrinsic dynamics.

Health utilities and quality-adjusted life years for patients with amyotrophic lateral sclerosis receiving or placebo in FORTITUDE-ALS.

Aims: To estimate the health utilities and quality-adjusted life years (QALYs) in patients with amyotrophic lateral sclerosis (ALS) receiving versus placebo in FORTITUDE-ALS.

Materials And Methods: We performed a post hoc analysis of clinical trial data from FORTITUDE-ALS (NCT03160898). This Phase IIb, double-blind, randomized, dose-ranging, placebo-controlled, parallel-group, 12-week trial evaluated in patients with ALS.

Levofloxacin-associated transient mixed sensorimotor lacunar syndrome.

Fluoroquinolones are commonly used antimicrobials with multiple known adverse effects, yet overdose events are rarely reported. Here, we report a case of a previously healthy middle-aged woman who unintentionally ingested 7 g of levofloxacin in one dose. Thereafter, she presented to the emergency department with hemiparesis concerning for ischaemic stroke and was administered tissue plasminogen activator.
