Thrombus Distribution in Vaccine-induced Immune Thrombotic Thrombocytopenia after ChAdOx1 nCov-19 Vaccination.

Vaccination strategies have been at the forefront of controlling the COVID-19 pandemic. An association between vaccine-induced immune thrombotic thrombocytopenia (VITT) and one of these vaccines, the ChAdOx1 nCov-19 vaccine, is now recognized. The purpose of this study was to investigate the frequency and location of thrombosis in each vascular system using CT, MRI, and US to identify additional sites of thrombus in a United Kingdom-wide sample of patients with confirmed VITT.

Management of massive splenomegaly.

A case demonstrating diagnostic and therapeutic rational for surgical management of massive splenomegaly.

Huntingtin-lowering strategies for Huntington's disease.

Introduction: Huntington's disease (HD) is an incurable, autosomal dominant neurodegenerative disease caused by an abnormally long polyglutamine tract in the huntingtin protein. Because this mutation causes disease via gain-of-function, lowering huntingtin levels represents a rational therapeutic strategy.

Areas Covered: We searched MEDLINE, CENTRAL, and other trial databases, and relevant company and HD funding websites for press releases until April 2020 to review strategies for huntingtin lowering, including autophagy and PROTACs, which have been studied in preclinical models.

Influence of Obesity on Complications, Clinical Outcome, and Subsidence After Anterior Lumbar Interbody Fusion (ALIF): Prospective Observational Study.

Background: The complications associated with obesity have been well described for posterior lumbar spinal surgery. However, the influence of obesity on anterior lumbar interbody fusion (ALIF) is not well established. We aimed to compare complication risks, functional outcomes, and subsidence rates in normal-weight, overweight, and obese patients who underwent ALIF.

Insights into the mechanisms of deep brain stimulation.

Despite long-term and widespread use of deep brain stimulation (DBS) in a variety of neurological conditions, the underlying mechanisms of action have been elusive. Growing evidence suggests that DBS acts through multimodal mechanisms that are not limited to inhibition and excitation of basal ganglia circuits. DBS also seems to act over variable time spans - for example, the effects on tremor are immediate, whereas the effects on dystonia emerge over several weeks - suggesting that large networks are targeted.
