OBJECTIVES: Severe coronavirus disease 2019 is associated with an extensive pneumonitis and frequent coagulopathy. We sought the true prevalence of thrombotic complications in critically ill patients severe on ICU, or without extracorporeal membrane oxygenation. DESIGN: undertook a single-center, retrospective analysis 72 2019-associated acute respiratory distress syndrome admitted to ICU. CT angiography thorax, abdomen, pelvis were performed at admission as per routine institution...

Spontaneous coronary artery dissection (SCAD) has been associated with fibromuscular dysplasia (FMD) and other extracoronary arterial abnormalities. However, the prevalence, severity, clinical relevance of these abnormalities remain unclear.To assess prevalence spectrum FMD in patients SCAD vs controls.This case series included 173 angiographically confirmed enrolled between January 1, 2015, December 31, 2019. Imaging beds was performed by magnetic resonance angiography (MRA). Forty-one...

Background: Partial anomalous venous connections (PAPVC) are associated with left to right shunting and heart dilatation. Identification of PAPVC has increased widespread use cross-sectional imaging modalities. However, management strategies mostly based on expert opinion given the scarcity data from large series. We aimed define types significance isolated atrial septal defect (ASD) detected by cardiovascular magnetic resonance. Methods: retrospectively reviewed our resonance database 2002...

Deoxycholic acid (DCA) is a secondary bile that modulates signalling pathways in epithelial cells. DCA has been implicated pathogenesis of colon carcinoma, particularly by activation the protein kinase C (PKC) pathway. Ursodeoxycholic (UDCA), tertiary acid, observed to have chemopreventative effects. The aim this study was investigate effect and UDCA on subcellular localization activity PKCη its downstream effects Golgi structure cancer cell model. expression localized HCT116 induced...

A number of females with pelvic inflammatory disease will present to general surgical services non-specific abdominal pain. Screening for sexually transmitted infections (STI) as an underlying cause is not routinely offered. We therefore established STI screening programme young presenting a same day emergency ambulatory clinic part the diagnostic pathway. Data outlining incidence and prevalence STIs lower pain were collected.

Abstract Background Prospective studies harnessing late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) afford the potential to non-invasively characterise phenotypic substrate for sudden cardiac death (SCD) and simultaneously interrogate its mechanistic drivers. Purpose To assess utility of infarct characterisation by CMR, including scar microstructure analysis, predict SCD in prospectively investigated patients with coronary heart disease (CHD). Methods Patients stable...
