The Application of Guideline-Based Care for Traumatic Brain and Spinal Cord Injury in Low- and Middle-Income Countries: A Provider-Based Survey.

Objective: Neurosurgical guidelines have resulted in improved clinical outcomes and more optimized care for many complex neurosurgical pathologies. As momentum in global neurosurgical efforts has grown, there is little understanding about the application of these guidelines in low- and middle-income countries.

Methods: A 29-question survey was developed to assess the application of specific recommendations from neurosurgical brain and spinal cord injury guidelines.

Current state of global neurosurgery activity amongst European neurosurgeons.

Background: The expanding field of global neurosurgery calls for a committed neurosurgical community to advocate for universal access to timely, safe, and affordable neurosurgical care for everyone, everywhere. The aim of this study was to assess the current state of global neurosurgery activity amongst European neurosurgeons and to identify barriers to involvement in global neurosurgery initiatives.

Methods: Cross-sectional study through dissemination of a web-based survey, from September 2019 to January 2020, to collect data from European neurosurgeons at various career stages.

Far Lateral Approaches: Dural Arteriovenous Fistulae at the Hypoglossal Canal: 3-Dimensional Operative Video.

Cognard type V dural arteriovenous fistulae (dAVF) are typically located at the foramen magnum. Their presentation often mimics that of cervical myelopathy, and they can be easily misdiagnosed even if spinal vascular imaging is undertaken. Treatment typically involves endovascular embolization or surgery when embolization is not possible.

Far Lateral Approaches: C1 Meningioma With Vertebral Artery Involvement: 3-Dimensional Operative Video.

Tumors around the cervicomedullary junction are rare and constitute 5% of spinal tumors and 1% of cranial tumors. The approach to these lesions is difficult because of the close proximity of the medulla and cervical spinal cord, lower cranial nerves, and vertebral artery (VA) as well as the complex articulation between occipital condyle, C1 and C2. Cervicomedullary junction meningiomas are commonly classified based on their origin in relation to the dentate ligament, but the relationship to the VA typically plays an important role in deciding the surgical approach.

Barriers to neurotrauma care in low- to middle-income countries: an international survey of neurotrauma providers.

Objective: Delays along the neurosurgical care continuum are associated with poor outcomes and are significantly greater in low- to middle-income countries (LMICs), with timely access to neurotrauma care remaining one of the most significant unmet neurosurgical needs worldwide. Using Lancet Global Surgery metrics and the Three Delays framework, the authors of this study aimed to identify and characterize the most significant barriers to the delivery of neurotrauma care in LMICs from the perspective of local neurotrauma providers.

Methods: The authors conducted a cross-sectional study through the dissemination of a web-based survey to neurotrauma providers across all World Health Organization geographic regions.

Longitudinal Changes in Size of Conservatively Managed Flow-Related Aneurysms Associated with Brain Arteriovenous Malformations.

Background: Flow aneurysms (FAs) associated with brain arteriovenous malformations (AVMs) are thought to arise from increased hemodynamic stress due to high-flow shunting. This study aims to describe the changes in conservatively managed FAs after successful AVM treatment.

Methods: Patients with symptomatic AVMs and associated FAs who underwent successful treatment of the AVM between 2008 and 2017 were included.

Medical students' experience of the hidden curriculum around primary care careers: a qualitative exploration of reflective diaries.

Objectives: Primary healthcare internationally is facing a workforce crisis with fewer junior doctors choosing general practice (GP) as a career. In the UK, a national report on GP careers highlighted adverse influences during medical school on students' career choices. The authors explored these influences in two urban UK medical schools, both with relatively low numbers of students entering GP training.

Post-haemorrhagic hydrocephalus is associated with poorer surgical and neurodevelopmental sequelae than other causes of infant hydrocephalus.

Purpose: This retrospective cohort study aimed to investigate the surgical and neurodevelopmental outcomes (NDO) of infant hydrocephalus. We also sought to determine whether these outcomes are disproportionately poorer in post-haemorrhagic hydrocephalus (PHH) compared to other causes of infant hydrocephalus.

Methods: A review of all infants with hydrocephalus who had ventriculoperitoneal (VP) shunts inserted at Great Ormond Street Hospital (GOSH) from 2008 to 2018 was performed.

Optimal Timing of External Ventricular Drainage after Severe Traumatic Brain Injury: A Systematic Review.

External ventricular drainage (EVD) may be used for therapeutic cerebrospinal fluid (CSF) drainage to control intracranial pressure (ICP) after traumatic brain injury (TBI). However, there is currently uncertainty regarding the optimal timing for EVD insertion. This study aims to compare patient outcomes for patients with early and late EVD insertion.

Interhemispheric control of sensory cue integration and self-motion perception.

Spatial orientation necessitates the integration of visual and vestibular sensory cues, in-turn facilitating self-motion perception. However, the neural mechanisms underpinning sensory integration remain unknown. Recently we have illustrated that spatial orientation and vestibular thresholds are influenced by interhemispheric asymmetries associated with the posterior parietal cortices (PPC) that predominantly house the vestibulo-cortical network.

Composite Grafts for Pediatric Fingertip Amputations: A Retrospective Case Series of 100 Patients.

Background: Fingertip amputations are common. This study reports on the outcomes of composite grafts used for fingertip amputations in children, measuring graft take, predictors of graft take, complications, and patient-reported outcomes.

Methods: A retrospective case series of consecutive patients (≤ 16 years) undergoing composite grafts for fingertip amputations in a tertiary pediatric hospital, January 06 to December 16, was performed.

Influence of biases in numerical magnitude allocation on human prosocial decision making.

Over the past decade neuroscientific research has attempted to probe the neurobiological underpinnings of human prosocial decision making. Such research has almost ubiquitously employed tasks such as the dictator game or similar variations (i.e.
