Exploring UK clinician perceptions of through-knee amputation compared to above-knee amputation: a mixed methods study.

Background: Through-knee amputation (TKA) has potential advantages over above-knee amputation (AKA) but is rarely performed in the United Kingdom (UK). This mixed methods study aimed to explore clinicians' perceptions of TKA compared to AKA.

Method: An online survey of vascular surgeons, prosthetists, and physiotherapists between May 2019 and April 2020.

New particle formation from isoprene under upper-tropospheric conditions.

Aircraft observations have revealed ubiquitous new particle formation in the tropical upper troposphere over the Amazon and the Atlantic and Pacific oceans. Although the vapours involved remain unknown, recent satellite observations have revealed surprisingly high night-time isoprene mixing ratios of up to 1 part per billion by volume (ppbv) in the tropical upper troposphere. Here, in experiments performed with the CERN CLOUD (Cosmics Leaving Outdoor Droplets) chamber, we report new particle formation initiated by the reaction of hydroxyl radicals with isoprene at upper-tropospheric temperatures of -30 °C and -50 °C.

An mRNA-encoded dominant-negative inhibitor of transcription factor RUNX1 suppresses vitreoretinal disease in experimental models.

Messenger RNA (mRNA)-based therapies are a promising approach to medical treatment. Except for infectious diseases, no other disease has mRNA-based therapies available. The eye is an ideal model for mRNA therapeutic development because it requires limited dosing.

Virtual Home Care for Patients With Acute Illness.

Importance: Recent evolutions in clinical care and remote monitoring suggest that some acute illnesses no longer require intravenous therapy and inpatient hospitalization.

Objective: To describe outcomes of patients receiving care in a new, outpatient, virtual, home-based acute care model called Safer@Home.

Design, Setting, And Participants: This retrospective cohort analysis, conducted from September 1, 2022, through August 31, 2023, included 2466 patients treated at a safety net hospital in Los Angeles County for 10 core illnesses and 24 other acute illnesses for which patients are commonly hospitalized.

Loss of the Endothelial Glycocalyx Component EMCN Leads to Glomerular Impairment.

Background: EMCN (endomucin), an endothelial-specific glycocalyx component, was found to be highly expressed by the endothelium of the renal glomerulus. We reported an anti-inflammatory role of EMCN and its involvement in the regulation of VEGF (vascular endothelial growth factor) activity through modulating VEGFR2 (VEGF receptor 2) endocytosis. The goal of this study is to investigate the phenotypic and functional effects of EMCN deficiency using the first global EMCN knockout mouse model.
