Cross-sectional study aimed to identify the components of a Roy's adaptation model in patients undergoing hemodialysis at a dialysis center. 178 patients participated in a dialysis center in the Brazil Northeast region. Data collection occurred from October/2011 to February/2012 through the use of interviews and physical examinations. The components identified were: adaptive problems, behaviors...

background: sulfatase 1 ( sulf1 ) function is to remove the 6-o-sulphate group from heparan sulfate. this action changes the binding sites of extracellular growth factors. sulf1 expression has been reported to be changed in angiogenesis. we hypothesized that single nucleotide polymorphisms (snps) of sulf1 would impact clinicopathologic characteristics. objective: study of sulf1 gene polymorphis...

The objective of this study is to investigated thermal diffusion and radiation effects on unsteady free convection chemically reacting fluid flow past an accelerated infinite inclined plate with variable temperature and mass diffusion under the influence of uniform transverse magnetic field when the magnetic lines of force are fixed relative to the fluid or to the plate studied in two cases, (i...

In the critical phase of dengue fever, the leakage of intravascular fluid into interstitial space and 3rd space can cause hemoconcentration and severe complications such as dengue shock syndrome (DSS), and it can lead to multiple organ failure, followed by death. Close monitoring, early detection and prompt management are the keys in successful treatment. In a hemodynamically unstable patient, ...

background: we have previously reported multiple health benefits in individuals following the christian-based fasting protocol known as the daniel fast (df). however, our prior work has involved only short-term (21-day) assessments. for dietary modification to have a profound impact on health, compliance to the dietary plan must be established for the long-term. materials and methods we determi...

Hyponatremia is the most frequent fluid and electrolyte disorder in hospitalized patients (20%), particularly in ICU, associated with an increase in morbility and mortality. While hypovolaemic hyponatremia needs to be corrected with the replacement of the lost extracellular fluid by isotonic saline, euvolaemic (SIADH) and hypervolaemic hyponatremia (oedematous states like decompensated heart fa...

OBJECTIVE We investigated whether the concentration of the glycoprotein fetuin A is altered in the second trimester amniotic fluid of trisomy 21 pregnancies compared with euploid pregnancies. METHODS 25 pregnancies with an extra chromosome 21 were matched for maternal and gestational age with 25 pregnancies with normal karyotype. Levels of fetuin A in amniotic fluid were measured by a commerc...

In anesthetized patients without cardiac arrhythmia the arterial pulse pressure variation (PPV) induced by mechanical ventilation has been shown the most accurate predictor of fluid responsiveness. In this respect, PPV has so far been used mainly in the decision-making process regarding volume expansion in patients with shock. As an indicator of the position on the Frank-Starling curve, PPV may...

Vascular remodeling under conditions of growth or exercise, or during recovery from arterial restriction or blockage is essential for health, but mechanisms are poorly understood. It has been proposed that endothelial cells have a preferred level of fluid shear stress, or 'set point', that determines remodeling. We show that human umbilical vein endothelial cells respond optimally within a rang...

Refractory ascites can occur in patients with various conditions. Although several procedures based on the reinfusion of ascitic fluid have been reported after the failure of bed rest, salt and water restriction, diuretics, intravenous administration of albumin, and repeated paracentesis, these procedures are performed for ascitic fluid removal without dialytic effect. In this study, a flow con...
