BACKGROUND The combined effect of blood pressure (BP) and body weight on risk of kidney disease has not been previously studied. To improve risk stratification in prehypertensive individuals (ie, BP, 120 to 139/80 to 89 mm Hg), we examined the interaction between BP and body weight on the risk of end-stage renal disease or chronic kidney disease(More)
The secular weight increase in European and US adolescents and the increasing use of oscillometric devices pose a problem to decide on normative blood pressure levels. We studied how biological and statistical aspects influence standards, and suggest new Northern Europe reference tables. All adolescents of Nord-Trøndelag county, Norway, aged 13-18 years(More)
BACKGROUND Peritonitis is considered to change peritoneal permeability and influences the long-term change in permeability during peritoneal dialysis. The objective of this study is to evaluate water transport across the peritoneum, expressed as drained ultrafiltration volume, before, during, and after episodes of peritonitis. METHODS A retrospective(More)
BACKGROUND Current knowledge on prepregnancy reduced kidney function and the risk of adverse pregnancy outcomes mainly relies on small studies in selected populations. We aim to investigate whether reduced kidney function is associated with the risk of adverse pregnancy-related outcomes in the general population. METHODS A population-based study linking(More)
BACKGROUND The natural course of longitudinal changes in peritoneal permeability and membrane area has been studied mostly by performing single-dwell studies in selected patients during treatment with peritoneal dialysis. PURPOSE To evaluate the permeability characteristics of the peritoneal membrane by measuring drained ultrafiltration volume relative to(More)
The concept of "isolated" left ventricular diastolic dysfunction has recently been challenged, since left ventricular contraction abnormalities can be demonstrated in subjects with normal left ventricular ejection fraction (EF). In this study of 35 healthy females (aged 65--80 years) with EF>50%, the ratio of peak early transmitral flow velocity to peak(More)
OBJECTIVE The interaction between left ventricular (LV) apical rotation, blood pressure (BP) and body mass in elderly females may reveal mechanisms involved in the syndrome of diastolic heart failure. METHODS Thirty-one healthy females, age 69-84 years, were studied with echocardiography, ambulatory BP and an exercise capacity (VO2peak) test. RESULTS LV(More)
