Missing the mark(ers): circulating endothelial cells and endothelial-derived extracellular vesicles are elevated in sickle cell disease plasma.

Sickle cell disease (SCD) is a devastating hemolytic disease, marked by recurring bouts of painful vaso-occlusion, leading to tissue damage from ischemia/reperfusion pathophysiology. Central to this process are oxidative stress, endothelial cell activation, inflammation, and vascular dysfunction. The endothelium exhibits a pro-inflammatory, pro-coagulant, and enhanced permeability phenotype.

Acute Kidney Injury in Patients with Cirrhosis and Chronic Kidney Disease: Results from the HRS-HARMONY Consortium.

Background & Aims: Chronic kidney disease (CKD) frequency is increasing in patients with cirrhosis and these individuals often experience acute kidney injury (AKI). Direct comparisons of outcomes between AKI-only versus AKI on CKD (AoCKD) among patients with cirrhosis are not well described.

Methods: A total of 2057 patients with cirrhosis and AKI across 11 hospital networks from the HRS-HARMONY consortium were analyzed (70% AKI-only and 30% AoCKD).

Weight, weight gain and behavioural risk factors in women attending a breast cancer family history, risk and prevention clinic: an observational study.

Background: Weight and health behaviours impact on breast cancer risk. We describe trends in weight and health behaviours in women at entry to a specialist breast cancer family history clinic in Manchester, UK, and changes after clinic entry.

Methods: Questionnaires were completed at clinic entry (1987-2019, n = 10,920), and updated in 2010-11 (n = 3283).

Centre-level fluid management practices in the BISTRO trial and their lack of association with participant fluid status and blood pressure in non-anuric haemodialysis patients.

Introduction: Fluid assessment and management is a key aspect of good dialysis care and is affected by patient-level characteristics and potentially centre-level practices. In this secondary analysis of the BISTRO trial we wished to establish whether centre-level practices with the potential to affect fluid status were stable over the course of the trial and explore if they had any residual associations with participant's fluid status.

Methods: Two surveys (S) of fluid management practices were conducted in 32 participating centres during the trial, (S1: 2017-18 and S2: 2021-22).

Impact of the Preservation of Residual Kidney Function on Hemodialysis Survival: Results from the BISTRO Trial.

Background: Preservation of residual kidney function (RKF) in dialysis patients has been associated with improved survival. RKF in the BISTRO trial was relatively well preserved and here we describe its association with survival during the trial and extended follow-up.

Methods: RKF, measured as the average urea and creatinine clearance (GFR) or 24-hour urine volume was assessed at baseline, one, two and three months and three-monthly up to 2 years in incident haemodialysis patients.
