Orthopedic Surgery <50 Days Following Covid-19 Infection Is Not Associated With Increased Postoperative Complications.

Background: Recent literature indicates that COVID-19 infection is a negative predictor of good outcomes following elective orthopedic surgery. However, the ideal timing of surgery after infection is unclear. The purpose of this study was to compare the rates of post-operative complications between those who underwent elective orthopedic surgery <50 days and >50 days after COVID-19 infection.

Have Degree, Will Travel? Geography and Orthopaedic Surgery Residency Match.

Introduction: The paucity of objective data on the residency application is challenging to Orthopedic Surgery residency programs when selecting candidates to interview and to rank. Qualifying or quantifying the effect of geography on match results will help programs screen and rank candidates more effectively. The aim of this study is to describe the geographic background of current Orthopedic Surgery residents in the United States relative to their current residency program.

A multidonor class of highly glycan-dependent HIV-1 gp120-gp41 interface-targeting broadly neutralizing antibodies.

Antibodies that target the gp120-gp41 interface of the HIV-1 envelope (Env) trimer comprise a commonly elicited category of broadly neutralizing antibodies (bNAbs). Here, we isolate and characterize VRC44, a bNAb lineage with up to 52% neutralization breadth. The cryoelectron microscopy (cryo-EM) structure of antibody VRC44.

A review of recent clinical trials to evaluate disease-modifying therapies in the treatment of cardiac amyloidosis.

Cardiac amyloidosis (CA) is a serious condition that results in infiltrative cardiomyopathy and heart failure with preserved ejection fraction (HFpEF) that is caused by the extracellular deposition of amyloid fibrils within heart tissue. While many important features of CA have been known for years, its prevalence in elderly patients with HF is increasingly being recognized. Plasma cells produce monoclonal immunoglobulin light chains which results in the formation and aggregation of amyloid fibrils that are responsible for AL amyloidosis.
