The purpose of this study is to assess the relative stability of the systolic and diastolic blood pressure (BP) measures obtained in a state-wide screening programme. A state-wide hypertension survey was conducted in California in 1983 in which a total of 6381 adults were interviewed in their homes. Three BP ...

Kidney transplant recipients as well as patients on hemodialysis frequently share an increased risk of cardiovascular diseases. Besides other factors, modulations in central neural blood pressure regulation have to be considered as a pathogenetic factor. In this study, baroreceptor function as a possible modulator of blood pressure and the activity ...

As the interlobular arteries of the ageing kidney progressively accumulate intimal fibroplasia, these fibroplastic changes appear to introduce strictures upon the interlobular arteries. These strictures are expected to generate nephron heterogeneity, which is a uniquely disturbed setting peculiarly suited to sustaining both high and low renin forms of hypertension. Fibroplastic ...

As a basis for chronobiologic analyses and thereby for screening deviant blood pressure, measurements are advocated, preferably with ambulatorily functional instrumentation at half-hour intervals around-the-clock for an initial span of 7 days. When only manual instrumentation is available, 3-hourly measurements during waking and one measurement, preferably by a companion, around ...

In clinical trials that study people with a continuous measure defined categorically, even repeated measurements within a visit and over successive visits do not prevent error-free classification. We describe the design of a screening procedure for the Systolic Hypertension in the Elderly Program (SHEP), a randomized clinical trial designed to ...

We developed an in vitro human kidney model to study the intrarenal pelvic pressures generated during percutaneous nephroscopy. Higher intrapelvic pressures were associated with nephroscopy sheaths of smaller caliber and greater length. In addition, the position of the sheath within the kidney markedly influenced intrapelvic pressure. The results of this ...

1. Disturbances of the blood pressure regulation, probably due to dysfunction of the autonomic nervous system, are well known complications in chronic renal failure. Haemodialysis and transplantation have been reported to ameliorate nerve dysfunction. 2. In this study, the function of the blood pressure control was investigated in kidney transplant ...

Hypertension in children has received minimal attention in the dental literature; this may be the result of comparatively low interest in the subject by the medical community. It is now believed that the processes causing cardiovascular disease morbidity and mortality begin early in life. The implication for prevention is that ...

The ankle-arm blood pressure index (AAI) is seldom used to screen for atherosclerotic diseases other than lower extremity arterial disease. This study was conducted to investigate whether the AAI can be used as a screening test for atherosclerotic diseases in general. The subjects were 446 male workers in a copper ...

Background: Early repair of coarctation of the aorta (COA) is associated with few perioperative complications and better long-term outcome. Therefore, early detection and treatment of COA patients is extremely desirable. The aim of this study was to review our referral system, the effectiveness of neonatal screening examination, and orient physicians ...

The association of cocaine and acute hypertension is well known; however, cocaine use has not generally been linked to chronic hypertension. We hypothesized that chronic use of cocaine over time would increase the prevalence of hypertension and that cocaine induced vasoconstriction would result in urine protein leakage, manifested by microalbuminuria. ...

Previous studies suggest that older honey bee workers possess an inhibitory signal that regulates behavioral development in younger bees. To study how this inhibitor is transmitted, bees were reared for 7 days in double-screen cages, single-screen cages, or unrestricted in a typical colony (control bees). Double-screen cages prevented physical contact ...

PURPOSE: We define the precise meaning and diagnostic significance of the resistance index generated by duplex scanning. MATERIALS AND METHODS: In 80 patients penile rigidity was clinically evaluated and a penile duplex scan was performed after intracavernous injection of 10 microg. prostaglandin E1. The intracavernous equilibrium pressure was measured in ...

Young people's understanding of sexual coercion was studied. Boys and girls (N = 191) were asked to rate scenarios depicting sexual situations according to their perceptions of communicative clarity, the extent of pressure being applied to one partner, and the acceptability of the behaviors. Judgments of communicative clarity were given ...

The syndrome of congestive heart failure is characterized by activation of many neurohormonal systems with vasoconstrictor and vasodilator actions. Data suggest that the stimulus that evokes this response is a threat to the arterial blood pressure. The long-term consequences of this response on the kidney are retention of sodium and ...

This study reports the use of computer-assisted sensorimotor testing in 75 patients with chronic peripheral nerve compression. Pinch and grip strength, and the cutaneous pressure threshold were measured. The reliability of this equipment for repeated measurements was excellent (r = 0.95). The pressure threshold at which a one-point static stimulus ...

How an increase in blood pressure, in and of itself, induces hypertensive nephrosclerosis is unclear. In an earlier study we found that leukocyte infiltration, proximal tubular cell proliferation, matrix deposition and interstitial fibrosis occur in the unclipped kidney of 2 K 1 C Goldblatt hypertensive rats. In this study we ...

Surveys taken of blood pressure in Greenland indicated prevailing levels similar to those in the USA. Morphometrically measured renovasculopathies in 88 autopsies confirmed blood pressure levels comparable to the survey findings. At clinic visits, the recorded blood pressures in 48 of the autopsies verified the morphometric conclusions (r = 0.559). ...

In order to identify a high-risk group for the development of arterial hypertension after extracorporeal shock wave nephrolithotripsy (ESWL), we correlated the increase in renovascular resistance induced by ESWL in 79 normotensive patients with changes in arterial blood pressure occurring 20 (+/- 3) months after therapy. Renal vascular resistance was ...
