Background

Stability of the spine and intervertebral disc (IVD) integrity is enabled by the highly organized fibrocartilaginous annulus fibrosus (AF). The shear properties of the AF are important in maintaining IVD integrity. AF shear mechanics in degenerative disc (DD) remain underexplored,...
The human mitochondrial genome encodes RNA components of its own translational machinery to produce the 13 mitochondrial-encoded subunits of the respiratory chain. Nuclear-encoded gene products are essential for all processes within the organelle, including RNA processing. Transcription of the mitoc...
The Delta (B.1.617.2) variant was the predominant UK circulating SARS-CoV-2 strain between May and December 2021. How Delta infection compares with previous variants is unknown. This prospective observational cohort study assessed symptomatic adults participating in the app-based COVID Symptom Study...

Background

More effective and safer treatments are needed for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis.

Methods

We conducted a randomized trial with a 2-by-2 factorial design to evaluate the use of plasma exchange and two regimens of oral glucocorticoids in pat...
Plastic pollution is distributed patchily around the world's oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, part...

Objective

The first COVID-19 pandemic wave was a period of reduced surgical activity and redistribution of resources to only those with late stage or critical presentations. This Vascular and Endovascular Research Network COVID-19 Vascular Service (COVER) study aimed to describe the six-mont...

Objective

The aim of the COVER Study is to identify global outcomes and decision making for vascular procedures during the pandemic.

Background data

During its initial peak, there were many reports of delays to vital surgery and the release of several guidelines advising later thresho...

Introduction

Postoperative morbidity and mortality in patients undergoing major emergency gastrointestinal surgery are a major burden on healthcare systems. Optimal management of perioperative intravenous fluids may reduce mortality rates and improve outcomes from surgery. Previous small tri...
