Bicarbonate supplementation preserves renal function in experimental chronic kidney disease (CKD), but whether the same benefit occurs in humans is unknown. Here, we randomly assigned 134 adult patients with CKD (creatinine clearance [CrCl] 15 to 30 ml/min per 1.73 m(2)) and serum bicarbonate 16 to 20 mmol/L to either supplementation with oral sodium(More)
BACKGROUND As terminal disease progresses, health deteriorates and the end of life approaches, people may ask "Why this illness? Why me? Why now?" Such questions may invoke, rekindle or intensify spiritual or religious concerns. Although the processes by which these associations occur are poorly understood, there is some research evidence for associations(More)
OBJECTIVES To study the effect of angiotensin-converting enzyme (ACE) polymorphisms II, ID, and DD on erythropoietin (EPO) requirement in patients on continuous ambulatory peritoneal dialysis (CAPD) therapy. DESIGN Retrospective observational study. SETTING CAPD Unit, Royal London/St. Bartholomews Hospital, London, UK. PATIENTS 46 patients on the(More)
BACKGROUND The corresponding antigens of alloantibodies identified in patients awaiting kidney transplantation are often listed as unacceptable for transplantation. The use of solid phase testing, being more sensitive and accurate than conventional complement-dependent cytotoxicity (CDC) assays, has resulted in increased identification of alloantibodies. We(More)
Diabetic nephropathy is the leading cause of end-stage renal disease in the Western world. Poor glycemic control contributes to the development of diabetic nephropathy, but the mechanisms underlying high glucose-induced tissue injury are not fully understood. In the present study, the effect of high glucose on a proximal tubular epithelial cell (PTEC) line(More)
BACKGROUND Complement activation plays a role in the development of chronic allograft nephropathy, a common cause of late allograft loss. The role of two complement component 3 (C3) allotypes, called C3F (fast) and C3S (slow) on the basis of their electrophoretic motility, in the long-term outcome of renal allografts remains controversial. METHODS We(More)
BACKGROUND Chronic inflammation, the common pathway that leads to cardiovascular disease and chronic allograft nephropathy after transplantation, is prevalent in patients with end-stage renal failure. We set out to investigate the hypothesis that enhanced pretransplantation C-reactive protein (CRP) levels and Chlamydia seropositivity, both markers of an(More)
OBJECTIVE Moderate renal impairment (RI) with a glomerular filtration rate (GFR) <60 ml/min/1.73 m2 is known to predict survival. The authors investigated whether mild RI with an estimated GFR of 60-89 ml/min/1.73 m2 independently predicts survival in a contemporary population with ST segment elevation myocardial infarction (STEMI). DESIGN This is a(More)
OBJECTIVES To determine the impact of introducing patient reported outcome measures (PROMs) on the selection of patients for surgery and on outcome for four elective operations (hip replacement, knee replacement, varicose vein surgery and groin hernia repair). METHODS Patient-level data from the National PROMs programme for England from April 2009 to(More)
BACKGROUND Attrition is a noted feature of eHealth interventions and trials. In 2005, Eysenbach published a landmark paper calling for a "science of attrition," suggesting that the 2 forms of attrition--nonusage attrition (low adherence to the intervention) and dropout attrition (poor retention to follow-up)--may be related and that this potential(More)
