Macular pigment measurement by heterochromatic flicker photometry in older subjects: the carotenoids and age-related eye disease study.

Purpose: To develop a standardized protocol for measuring macular pigment optical density (MPOD) of experimentally naïve subjects by heterochromatic flicker photometry (HFP).

Methods: MPOD in eyes of 54 women, age 50 and 79 years (mean, 66), was studied. The spatial profile of MPOD was measured in the right eye, and two spatial points were also measured in the left eye.

Long-term outcome of diabetic patients receiving peritoneal dialysis.

Objective: Data from the United States Renal Data Systems (USRDS) suggest that older diabetic patients with end-stage renal disease will have improved survival if they receive hemodialysis versus peritoneal dialysis. Younger diabetic patients have equal survival on either treatment modality. To address more specifically the risk factors for long-term survival of diabetic patients receiving peritoneal dialysis, we analyzed the long-term outcome of 118 diabetics receiving peritoneal dialysis over a decade and compared them to 165 nondiabetic patients.

Risk factors for peritoneal dialysis-related infections.

Objective: To identify factors associated with peritoneal dialysis-related infections at one center.

Design: The study was a retrospective study of a 3-year time period with relatively stable treatment patterns.

Setting: A single center experienced academic peritoneal dialysis program.

Effect of peritonitis on plasma and dialysate alpha 1-acid glycoprotein concentrations in peritoneal dialysis patients.

The effect of peritonitis on plasma and dialysate alpha 1-acid glycoprotein (AAG) concentrations was determined. Plasma and dialysate samples were obtained at the onset of infection and one month after treatment from 10 peritoneal dialysis patients with peritonitis. Plasma and dialysate samples were also obtained from 10 noninfected matched controls.

Pharmacokinetics of intraperitoneal, intravenous, and subcutaneous recombinant human erythropoietin in patients on continuous ambulatory peritoneal dialysis.

The pharmacokinetics of recombinant human erythropoietin (Epo) were compared after mean single 99.1 U/kg intraperitoneal (IP), intravenous (i.v.
