Chorioallantoic membrane (CAM) assay to study treatment effects in diffuse intrinsic pontine glioma.

Diffuse intrinsic pontine glioma (DIPG) is a lethal pediatric brain tumor. While there are a number of in vivo rodent models for evaluating tumor biology and response to therapy, these models require significant time and resources. Here, we established the chick-embryo chorioallantoic (CAM) assay as an affordable and time efficient xenograft model for testing a variety of treatment approaches for DIPG.

Altered mental status in COVID-19.

Background: Altered mental status (AMS) is a common neurological manifestation of COVID-19 infection in hospitalized patients. The principal causes of AMS have yet to be determined. We aimed to identify the common causes of AMS in patients with COVID-19 presenting to the emergency department with AMS on arrival.

Neurologic Syndromes Predict Higher In-Hospital Mortality in COVID-19.

Objective: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is protean in its manifestations, affecting nearly every organ system. However, nervous system involvement and its effect on disease outcome are poorly characterized. The objective of this study was to determine whether neurologic syndromes are associated with increased risk of inpatient mortality.

Predictors of mortality for patients with COVID-19 and large vessel occlusion.

Background: This study evaluates the mortality risk of patients with emergent large vessel occlusion (ELVO) and COVID-19 during the pandemic.

Methods: We performed a retrospective cohort study of two cohorts of consecutive patients with ELVO admitted to a quaternary hospital from March 1 to April 17, 2020. We abstracted data from electronic health records on baseline, biomarker profiles, key time points, quality measures and radiographic data.
