Analysis of Glomerular Transcriptomes from Nephrotic Patients Suggest Risk Variants Impact Parietal Epithelial Cells.

The disproportionate risk for idiopathic proteinuric podocytopathies in Black people is explained, in part, by the presence of two risk alleles (G1 or G2) in the gene. The pathogenic mechanisms responsible for this genetic association remain incompletely understood. We analyzed glomerular RNASeq transcriptomes from patients with idiopathic nephrotic syndrome of which 72 had inferred African ancestry (AA) and 152 did not (noAA).

Malnutrition in Spine Oncology: Where Are We and What Are We Measuring?

Study Design: Scoping review.

Objective: To identify which markers are used as surrogates for malnutrition in metastatic spine disease and which are the most studied outcomes associated with it.

Methods: A scoping review was performed by searching the PubMed/Medline, EMBASE, and Web of Science databases up to July 2022.

Appropriate Use Criteria for Neoplastic Compression Fractures.

Background Context: Clinical outcomes are directly related to patient selection and treatment indications for improved quality of life. With emphasis on quality and value, it is essential that treatment recommendations are optimized.

Purpose: The purpose of the North American Spine Society (NASS) Appropriate Use Criteria (AUC) is to determine the appropriate (ie, reasonable) multidisciplinary treatment recommendations for patients with metastatic neoplastic vertebral fractures across a spectrum of more common clinical scenarios.

Risk Factors for the Development of Neurological Deficits in Metastatic Spinal Disease: An International, Multicenter Delphi Study.

Study Design: Delphi study.

Objective: The objective of this study was to identify risk factors associated with the development and/or progression of neurological deficits in patients with metastatic spinal disease.

Methods: A three-round Delphi study was conducted between January-May 2023 including AO Spine members, comprising mainly neurosurgeons and orthopedic surgeons.

A Critical Appraisal of the Application of Frailty and Sarcopenia in the Spinal Oncology Population.

Study Design: Systematic review and clinimetric analysis.

Objectives: Frailty and sarcopenia predict worse surgical outcomes among spinal degenerative and deformity-related populations; this association is less clear in the context of spinal oncology. Here, we sought to identify frailty and sarcopenia tools applied in spinal oncology and appraise their clinimetric properties.
