A Multinational, Multicenter Study Mapping Models of Kidney Supportive Care Practice.

Introduction: Kidney supportive care (KSC) integrates kidney and palliative care to improve quality of life for people with chronic kidney disease (CKD). Despite increasing interest and global advocacy to integrate KSC into kidney care, evidence to guide optimal care delivery is limited.

Methods: This observational cross-sectional study used an online survey to describe current KSC models in Australia, Aotearoa-New Zealand, and the UK.

Predicting Kidney Failure, Cardiovascular Disease and Death in Advanced CKD Patients.

Introduction: Predicting the timing and occurrence of kidney replacement therapy (KRT), cardiovascular events, and death among patients with advanced chronic kidney disease (CKD) is clinically useful and relevant. We aimed to externally validate a recently developed CKD G4+ risk calculator for these outcomes and to assess its potential clinical impact in guiding vascular access placement.

Methods: We included 1517 patients from the European Quality (EQUAL) study, a European multicentre prospective cohort study of nephrology-referred advanced CKD patients aged ≥65 years.

'Mali Matters': reflections on a leadership and quality improvement project to improve blood transfusion safety at Maluti Adventist Hospital, Mapoteng, Lesotho.

Introduction: This report outlines a quality improvement (QI) project aiming to improve blood transfusion safety at Maluti Adventist Hospital (MAH), Lesotho, from August 2019 to January 2020.The project team comprised nine local staff members and two UK doctors working through the NHS 'Improving Global Health through Leadership Development' (IGH) programme.

Methods: Baseline data was gathered and a 'process mapping' meeting held to understand existing processes and identify methods for improvement.

Non-infectious aortitis in an immunosuppressed renal transplant recipient with IgA nephropathy.

A 54-year-old woman presented with atypical chest pain, fever and malaise. She was immunosuppressed with three agents following a living-donor kidney transplant 1 year previously. Her native kidney failure was secondary to biopsy-demonstrated crescentic IgA nephropathy, with systemic involvement.

NAADP activates two-pore channels on T cell cytolytic granules to stimulate exocytosis and killing.

A cytotoxic T lymphocyte (CTL) kills an infected or tumorigenic cell by Ca(2+)-dependent exocytosis of cytolytic granules at the immunological synapse formed between the two cells. Although inositol 1,4,5-trisphosphate (IP(3))-mediated Ca(2+) release from the endoplasmic reticulum activates the store-operated Ca(2+)-influx pathway that is necessary for exocytosis, it is not a sufficient stimulus. Here we identify the Ca(2+)-mobilizing messenger nicotinic acid adenine dinucleotide phosphate (NAADP) and its recently identified molecular target, two-pore channels (TPCs), as being important for T cell receptor signaling in CTLs.
