Early Prophylactic Hypothermia for Patients With Severe Traumatic Injury: Premature to Close the Case
This study demonstrates that there is no role for the initiation of hypothermia during the acute phase of TBI (1, 2). However, it would be damaging to abandon the concept prematurely. Inflammation Also Paves the Way to Tissue Repair As soon as trauma occurs, the inflammatory cascade begins to take place. The deleterious role of inflammation in the secondary injury response is well-documented, hence the rationale to attempt early prophylactic hypothermia in TBI. However, inflammation also initiates tissue repair and regeneration (3–6). We now know that the secondary injury response accompanies the regenerating and...

Pre-injury Comorbidities Are Associated With Functional Impairment and Post-concussive Symptoms at 3- and 6-Months After Mild Traumatic Brain Injury: A TRACK-TBI Study
Conclusions: Pre-injury psychiatric and pre-injury headache/migraine symptoms are risk factors for worse functional and post-concussive outcomes at 3- and 6-months post-mTBI. mTBI patients presenting to acute care should be evaluated for psychiatric and headache/migraine history, with lower thresholds for providing TBI education/resources, surveillance, and follow-up/referrals. Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT01565551. Introduction Traumatic brain injury (TBI) remains a significant cause of morbidity and mortality worldwide. In 2013 ~2.8 million TBI cases were recorded an...

Stenosis Length and Degree Interact With the Risk of Cerebrovascular Events Related to Internal Carotid Artery Stenosis
Conclusion: We found a statistically insignificant tendency for the ultrasound-measured length of sICAS<70% to be longer than that of sICAS≥70%. Moreover, the ultrasound-measured length of sICAS<90% was significantly longer than that of sICAS 90%. Among patients with sICAS≥70%, the degree and length of stenosis were inversely correlated. Larger studies are needed before a clinical implication can be drawn from these results. Introduction Internal carotid artery stenosis (ICAS) causes around one-fifth of ischemic cerebrovascular stroke and has the highest risk of early stroke recurrence...

Healthcare Economics of Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage in the United States
AbstractHydrocephalus is one of the most common sequelae after aneurysmal subarachnoid hemorrhage (aSAH), and it is a large contributor to the condition ’s high rates of readmission and mortality. Our objective was to quantify the healthcare resource utilization (HCRU) and health economic burden incurred by the US health system due to post-aSAH hydrocephalus. The Truven Health MarketScan® Research database was used to retrospectively quantify the prevalence and HCRU associated with hydrocephalus in aSAH patients undergoing surgical clipping or endovascular coiling from 2008 to 2015. Multivariable longitudinal analysis w...

Abstract #7: HD-tDCS to contralesional hemisphere to enhance treatment outcomes in persons with stroke-induced aphasia
Background: Chronic aphasia, or language difficulty persisting beyond one year post-stroke, affects over 2.5 million individuals in the United States. Treatment response varies and language abilities are rarely restored. Intact, connected ipsilesional language areas and improved interhemispheric balance following stroke are consistent predictors of recovery. A promising approach to target these brain dynamics is using high-definition transcranial direct current stimulation (HD-tDCS) to deliver focal cathodal current to right frontal areas in the contralesional hemisphere, combined with efficacious behavioral treatment that...

Publication trends in transcranial magnetic stimulation: a 30-year panorama
ConclusionThis study implemented a systematic, bibliometric approach to quantitively assess the breadth of the TMS literature base and identify temporal publication and authorship trends. Drawing on these insights may aid understanding of historical progress in TMS over the last 30 years and help identify into unmet needs and opportunities to improve scientific and publishing practices to contribute to the future health of the field. These findings are likely to be relevant to researchers, clinicians, funders, industry collaborators and other stakeholders.

Trends in Interhospital Transfers and Mechanical Thrombectomy for United States Acute Ischemic Stroke Inpatients
Objective: Stroke care in the US is increasingly regionalized. Many patients undergo interhospital transfer to access specialized, time-sensitive interventions such as mechanical thrombectomy. Methods: Using a stratified survey design of the US Nationwide Inpatient Sample (2009-2014) we examined trends in interhospital transfers for ischemic stroke resulting in mechanical thrombectomy. International Classification of Disease —Ninth Revision (ICD-9) codes were used to identify stroke admissions and inpatient procedures within endovascular-capable hospitals.

Geographic Disparities in the Incidence of Stroke among Patients with Atrial Fibrillation in the United States
Aim: To determine whether regional variation in stroke incidence exists among individuals with AF. Methods: Using healthcare utilization claims from 2 large US databases, MarketScan (2007-2014) and Optum Clinformatics (2009-2015), and the 2010 US population as the standard, we estimated age-, sex-, race- (only in Optum) standardized stroke incidence rates by the 9 US census divisions. We also used Poisson regression to examine incidence rate ratios (IRR) of stroke and the probability of anticoagulation prescription fills across divisions.

Treatment of a hot carotid: More fuel is needed to clarify the best treatments
The majority of patients presenting with a stroke or TIA receive imaging for carotid stenosis. Treatment of symptomatic carotid stenosis is familiar to most neurologists since high-profile clinical trials have been conducted in the past. The most well-known in North America is the North American Symptomatic Carotid Endarterectomy Trial (NASCET).1 NASCET and additional analysis by Rothwell et al.2 led to the recommendation that if the patient is an otherwise suitable candidate for carotid endarterectomy (CEA), then performing the operation within 2 weeks of the last symptomatic event is desirable.
