Abstract

The objectives of this study were to perform bioelectrical impedance analysis before and after heart transplantation with comparison to healthy subjects. Eight patients (7 men, 1 woman) before (day 0) and after transplantation (day 3, 7, 12, 15, and 180) and 24 healthy controls, matched for sex, age, and body mass were studied. Data collection included bioelectrical impedance analysis (resistance, reactance, and estimates of body water), clinical, and laboratory measurements. Compared with controls, patients had at baseline significantly higher reactance, not significantly different resistance, body weight, total body water, and intra- to extracellular water ratio. After surgery, for reactance, there was an acute decrease followed by a slow, progressive increase up to normal level by day 15. Resistance and body weight did not significantly change; the intra- to extracellular water ratio significantly decreased with stable total body water. Changes in reactance are the main effects induced on bioelectrical impedance by heart transplantation. Acutely, there is a large decrease which likely reflects changes both in water distribution and in cell membrane function. The late changes more likely reflect the shift of body water from the extra- to the intracellular space with stable total body water.

Abstract

This work studies protease concentration decrease in aqueous solutions in contact with a modified polyethersulphone graft membrane onto which antiproteases were immobilized. As a model of protease/antiprotease interaction, elastase and a1-antitrypsin were used. Experiments were carried out either under fixed amounts of immobilized antiproteases and variable protease concentration or under fixed protease concentration and variable amounts of immobilized antiproteases. In both cases, active protease concentrations decreased with increase in contact time with the membrane. Experimental conditions under which active elastase concentration becomes zero were also found. Occurrence of the same phenomenology has also been ascertained with protease solutions obtained from human blood neutrophyls. The membrane activated with a1-antitrypsin showed differential inhibitory power on elastase and cathepsin G. This technology allows construction of the most appropriate membranes to be used in hemodialysis and extracorporeal circulation when elastase is released.

Abstract

Renal reserve was explored by means of an oral protein load (2 g/kg body weight) under the form of cooked red meat in a group of 9 patients with end-stage heart failure (ESHF), class III of the New York Heart Association receiving loop diuretics and angiotensin-converting enzyme (ACE) inhibitors, and in a group of 18 healthy controls (HC) matched for age, gender, and height under an identical dietary regimen providing 40 cal/kg per day, 1 g/kg body weight of protein per day, Na 120 mmol/day, and K 50 mmol/day. Baseline glomerular filtration rate averaged 109.5±9.89 ml/min×1.73 m2 in HC and 71.9±8.8 ml/min×1.73 m2 in ESHF. Renal plasma flow averaged 540±27 ml/min×1.73 m2 in HC and 235±47 ml/min×1.73 m2 in ESHF. The filtration fraction was significantly higher in ESHF (p2 in HC and 27.2±7.12 ml/min×1.73 m2 (not significant). Renal reserve averaged 123.9±2.9% in HC and 137.3±6.68% in ESHF (not significant).

Abstract

This study adds another category of patients to those amenable to body impedance analysis (BIA). BIA measurements were obtained for the first time in 23 male patients with end-stage heart failure who were waiting for heart transplantation, and the data were compared with those obtained in 69 healthy controls matched for age, sex, height and weight. The data indicate that in end-stage heart failure there is an increased reactance (p

Abstract

We treated nine patients having severe heart failure (IV NYHA classification) with anuria resistant to diuretics who were on daily hemofiltration, and estimated their survival for a year. The total volume of liquids removed was estimated by means of an echographic determination of the caval collapsability index. Dry weight was obtained from 6 to 22 days. The fluid removed varied from 10 to 35 liters. Five patients at the end of the therapy took up diuresis again and recovered their sensitivity to diuretics. Three of these patients went beyond the 12 months of survival, and two patients died earlier. Four patients did not show the resumption of diuresis and they continued with daily hemofiltration. Three survived over 20 weeks; one died after 15 weeks. We conclude that daily hemofiltration is useful in patients with severe heart decompensation in that it increases their survival rate.

Abstract

In this study Bioelectrical Impedance Analysis was performed in 5 patients with end stage heart failure in whom a left ventricular assist device (Novacor) was successfully implanted. Whole body measurements of bioelectrical indices resistance and reactance were taken before surgery and 3, 7, 12, and 15 days after it. After surgery there was a significant decrease in reactance, indicating a shift of body fluids from intra- to extra-cellular space.

Abstract

Greek philosophy finds its roots in the myth of Homer's and Hesiod's poems and especially in Orphism which introduced the concept of a soul separated from the body with an independent principle, psichē (soul), to be rewarded or punished after death. Orphism was an important step in Greek culture. It introduced the divine into man, the soul which does not die with the body and reincarnates. From Orphism started the need of rituals capable of separating the spirit from the body. From Homer to Acusilaos, water was a very important element which connected humans and gods, long before Thales of Miletus defined it the arche.
