Affinity Purification Mass Spectrometry on the Orbitrap-Astral Mass Spectrometer Enables High-Throughput Protein-Protein Interaction Mapping.

Classical proteomics experiments offer high-throughput protein quantification but lack direct evidence of the spatial organization of the proteome, including protein-protein interaction (PPIs) networks. While affinity purification mass spectrometry (AP-MS) is the method of choice for generating these networks, technological impediments have stymied the throughput of AP-MS sample collection and therefore constrained the rate and scale of experiments that can be performed. Here, we build on advances in mass spectrometry hardware that have rendered high-flow liquid chromatography separations a viable solution for faster throughput quantitative proteomics.

The EMCV protein 2B* is required for efficient cell lysis via both caspase-3-dependent and -independent pathways during infection.

2B* is a poorly characterized protein encoded by an overlapping ORF in the genome of encephalomyocarditis virus (EMCV). We have previously found 2B* to have a role in innate immune antagonism; however, this role is distinct from an earlier described phenotype whereby 2B*KO viruses exhibit extremely small plaques compared to WT. Here, we report that the small plaque phenotype is recapitulated by novel EMCV mutant viruses harbouring mutations across the C-terminal domain of 2B*, confirming a functional role of 2B* in promoting viral spread.

Large-scale evaluation of outcomes after a genetic diagnosis in children with severe developmental disorders.

Purpose: We sought to evaluate outcomes for clinical management after a genetic diagnosis from the Deciphering Developmental Disorders study.

Methods: Individuals in the Deciphering Developmental Disorders study who had a pathogenic/likely pathogenic genotype in the DECIPHER database were selected for inclusion ( = 5010). Clinical notes from regional clinical genetics services notes were reviewed to assess predefined clinical outcomes relating to interventions, prenatal choices, and information provision.

Decreasing Hospital-acquired Pressure Injuries During the COVID-19 Pandemic: A 5-step Quality Improvement Approach.

Background: Hospital-acquired pressure injuries (HAPIs) are common adverse events with large burdens on patients and health systems. In 2020, during the initial waves of the COVID-19 pandemic, the incidence of admitted patients with HAPIs of stage II and above in our health system rose from 2.92% to 3.

The inequalities and challenges of prehabilitation before cancer surgery: a narrative review.

Introduction: Prehabilitation seeks to enhance functional capacity and preparedness before surgery with the aim of improving outcomes; it is generally based on exercise, diet and psychological interventions. While there is obvious appeal to this approach in terms of patient experience and resource use, the interventions are complex and the evidence base for prehabilitation before cancer surgery is heterogeneous. Prehabilitation requires patient understanding and motivation as well as commitment of resources.
