BACKGROUND The majority of dialysis patients suffer from vitamin D deficiency, which might contribute to an adverse health outcome. We aimed to elucidate whether European dialysis patients with low 25-hydroxyvitamin D (25(OH)D) levels are at increased risk of mortality and specific fatal events. METHODS This was a prospective cohort study of incident(More)
AIMS Dialysis patients experience an excess mortality, predominantly of sudden cardiac death (SCD). Accumulating evidence suggests a role of vitamin D for myocardial and overall health. This study investigated the impact of vitamin D status on cardiovascular outcomes and fatal infections in haemodialysis patients. METHODS AND RESULTS 25-hydroxyvitamin D(More)
BACKGROUND AND OBJECTIVES We compared the estimations of Cockcroft-Gault, Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations to a gold standard GFR measurement using (125)I-iothalamate, within strata of GFR, gender, age, body weight, and body mass index (BMI). DESIGN, SETTING,(More)
Peacocks are a classic example of sexual selection, where females preferentially mate with males who have longer, more elaborate trains. One of the central hypotheses of sexual selection theory is that large or elaborate male 'ornaments' may signal high genetic quality (good genes). Good genes are thought to be those associated with disease resistance and(More)
BACKGROUND There are only a few risk factors known for primary patency loss in patients with an arteriovenous graft or fistula. Furthermore, a limited number of studies have investigated the association between arteriovenous access modality and primary patency loss and mortality. The aim of this study was to investigate risk factors for patency loss and to(More)
BACKGROUND AND OBJECTIVES Although women have a survival advantage in the general population, women on dialysis have similar mortality to men. We hypothesized that this paired mortality risk during dialysis may be explained by a relative excess of cardiovascular-related mortality in women. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We compared 5-year(More)
Apomictic plants often produce pollen that can function in crosses with related sexuals. Moreover, facultative apomicts can produce some sexual offspring. In dandelions, Taraxacum, a sexual-asexual cycle between diploid sexuals and triploid apomicts, has been described, based on experimental crosses and population genetic studies. Little is known about the(More)
BACKGROUND AND OBJECTIVES Automated peritoneal dialysis (APD) is increasingly used in comparison with continuous ambulatory peritoneal dialysis (CAPD). Although APD is expected to improve survival, convincing evidence of major advantages is lacking. The objective was to investigate whether overall mortality and technique failure of incident dialysis(More)
BACKGROUND AND OBJECTIVES We compared the decline of RRF in patients starting dialysis on APD with those starting on CAPD, because a faster decline on APD has been suggested. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS NECOSAD patients starting dialysis on APD or CAPD with RRF at baseline were included and followed for 3 years. Residual GFR (rGFR) was(More)
BACKGROUND Although an association between venous thrombosis and chronic kidney disease has recently been established, it is unknown which patients with chronic kidney disease are most likely to benefit from thromboprophylaxis. OBJECTIVE The aim of this study was to assess the association between venous thrombosis and chronic kidney disease in combination(More)
