The Synergy between Topography and Lipid Domains in the Plasma Membrane of Mast Cells Controls the Localization of Signaling Proteins and Facilitates their Coordinated Activation.

Similar to T cells and B cells, mast cell surfaces are dominated by microvilli, and like these other immune cells we showed with microvillar cartography (MC) that key signaling proteins for RBL mast cells localize to these topographical features. Although stabilization of ordered lipid nanodomains around antigen-crosslinked IgE-FcεRI is known to facilitate necessary coupling with Lyn tyrosine kinase to initiate transmembrane signaling in these mast cells, the relationship of ordered-lipid nanodomains to membrane topography had not been determined. With nanoscale resolution provided by MC, SEM and co-localization probability (CP) analysis, we found that FcεRI and Lyn kinase are positioned exclusively on the microvilli of resting mast cells in separate nano-assemblies, and upon antigen-activation they merge into overlapping populations together with the LAT scaffold protein, accompanied by elongation and merger of microvilli into ridge-like ruffles.

Critical care EEG monitoring in children with abusive head trauma: A retrospective study of seizure burden and predictors of neurological outcomes.

Objectives: Abusive Head Trauma (AHT) remains an important cause of acute seizures, morbidity, and mortality in children. We aimed to assess the clinical and electrographic seizure burden in children with AHT and to explore predictors of morbidity and mortality.

Methods: We conducted a retrospective chart review of all children admitted with AHT who underwent continuous electroencephalographic monitoring (cEEG) between January 1st, 2015, and April 15th, 2021.

Endoscopic Management of Laryngotracheal Disease.

Laryngotracheal stenosis (LTS) encompasses a spectrum of conditions characterized by the luminal narrowing of the supraglottis, glottis, subglottis, and/or trachea. However, endoscopic treatment methods are associated with significantly higher rates of restenosis compared to open techniques. The number of endoscopic modalities continues to expand without a clear consensus on the most appropriate treatment choice.

Patient buy-in to social prescribing through link workers as part of person-centred care: a realist evaluation.

Background: Social prescribing link workers have become part of primary health care in recent years. They help patients to recognise non-medical factors affecting their health and identify sources of support, often in the voluntary, community and social enterprise sector. They form part of wider work to strengthen person-centred care, which actively seeks to engage individuals in decision-making about their health, taking into account their medical, social, psychological, financial and spiritual circumstances.

Experiences of integrating social prescribing link workers into primary care in England: Bolting on, fitting in or belonging.

Background: Following the 2019 NHS Long-Term Plan, link workers (LWs) have been employed across primary care in England to deliver social prescribing (SP).

Aim: To understand and explain how the LW role is being implemented in primary care in England.

Design And Setting: Realist evaluation undertaken in England.
