Dendritic spines receive most excitatory inputs in the CNS and compartmentalize calcium. Although the mechanisms of calcium influx into spines have been explored, it is unknown what determines the calcium decay kinetics in spines. With two-photon microscopy we investigate action potential-induced calcium dynamics in spines from rat CA1 pyramidal neurons in(More)
The European APD Outcome Study (EAPOS) is a 2-yr, prospective, multicenter study of the feasibility and clinical outcomes of automated peritoneal dialysis (APD) in anuric patients. A total of 177 patients were enrolled with a median age of 54 yr (range, 21 to 91 yr). Previous median total time on dialysis was 38 mo (range, 1.6 to 259 mo), and 36% of(More)
BACKGROUND Encapsulating peritoneal sclerosis (EPS) is a disease process that can occur as a complication of peritoneal dialysis (PD). The aim of this study was to make a general assessment of the clinical features, diagnosis, management and outcome of PD-related EPS cases from London and South-East England. METHODS Questionnaires were sent to 11 PD units(More)
BACKGROUND Evidence-based health policy is urgently needed to meet the increasing demand for health services among elderly people, particularly for expensive technologies such as renal-replacement therapy. Age has been used to ration dialysis, although not always explicitly, despite the lack of rigorous empirical evidence about how elderly people fare on(More)
Encapsulating peritoneal sclerosis (EPS) is a rare complication of peritoneal dialysis (PD), but carries significant morbidity and mortality. We review the clinical features and radiologic and histologic changes found at diagnosis of EPS. Although EPS is strongly associated with the duration of PD, the pathogenesis remains only partly understood. We discuss(More)
BACKGROUND Health-related quality of life (QOL) is an important outcome for older people who are often on dialysis for life. Little is, however, known about differences in QOL on haemodialysis (HD) and peritoneal dialysis (PD) in older age groups. Randomising patients to either modality to assess outcomes is not feasible. METHODS In this cross-sectional,(More)
Malnutrition is a common complication in patients on dialysis and is strongly associated with poor prognosis. Effective therapy could substantially improve morbidity and mortality, but neither enteral nor parenteral supplementation provide long-term benefit because of the strong appetite suppression seen in such patients. We performed a double-blinded(More)
To reduce the use of vancomycin, the current recommendations of the International Society of Peritoneal Dialysis (PD) for the initial treatment of peritonitis complicating PD are to administer intraperitoneal (IP) cefazolin or cephalothin in every PD fluid bag, together with once-daily gentamicin. In view of the inherent impracticalities of this regimen, we(More)
