Raymond R. Townsend

About

Raymond R. Townsend, MD, is an Emeritus Professor of Medicine and the Chief of Medicine (Renal-Electrolyte and Hypertension) at the University of Pennsylvania School of Medicine. He serves as the Director of the Hypertension Section within the Department of Internal Medicine/Renal. His research interests include the progression of chronic kidney disease, insulin resistance, measurement of vascular compliance, euglycemic clamp technique, minimal model for glucose kinetics, stable isotope metabolism, indirect calorimetry, measurement of regional blood flow, and measurement of glomerular filtration rate (GFR). Dr. Townsend's clinical expertise focuses on hypertension, including cases associated with adrenal tumors such as Pheochromocytoma and Paraganglioma, as well as conditions like Conn's Syndrome, Aldosterone Excess, hypertension with renal vascular disease, and refractory (drug-resistant) hypertension. His educational background includes a B.A. in Biology from LaSalle College and an M.D. from Hahnemann University. He has contributed to the field through numerous publications and is actively involved in research related to nephrology and hypertension.

  reviewOpen access

  BACKGROUND: Although measuring albuminuria is the preferred method for defining and staging chronic kidney disease (CKD), total urine protein or dipstick protein is often measured instead. OBJECTIVE: To develop equations for converting urine protein-creatinine ratio (PCR) and dipstick protein to urine albumin-creatinine ratio (ACR) and to test their diagnostic accuracy in CKD screening and staging. DESIGN: Individual participant-based meta-analysis. SETTING: 12 research and 21 clinical cohorts.…
