BACKGROUND: Vascular calcification is one of the risk factors for arterial stiffness in patients with chronic kidney disease. We hypothesized that a mismatch between elastic and muscular arteries, represented as pulse wave velocity (PWV) ratio, could depict the extent of vascular calcification in end-stage renal disease. We also aimed to compare the predictive PWV ratio value to other factors possibly related to vascular calcification in dialysis population. METHODS: In this cross-sectional study, in 60 chronic dialysis patients without previous cerebrovascular events, cardiovascular disease and events or clinically evident peripheral artery disease (ankle-brachial index >0...

Changes in BOLD signals are sensitive to the regional blood content associated with the vasculature, which is known as V0 in hemodynamic models. In previous studies involving dynamic causal modeling (DCM) which embodies the hemodynamic model to invert the functional magnetic resonance imaging signals into neuronal activity, V0 was arbitrarily set to a physiolog-ically plausible value to overcome the ill-posedness of the inverse problem. It is interesting to investigate how the V0 value influences DCM. In this study we addressed this issue by using both synthetic and real experiments...

Intradialytic hypotension is the most common complication associated with hemodialysis. We describe a case of severe intradialytic hypotension during routine chronic dialysis, the presenting symptom of hypocalcemia due to a procedural error involving a zero calcium liquid acid dialysate concentrate. Although human factors were the root cause of this event, we discuss physical and procedural controls that may help to minimize the risk of human error. Citrate anticoagulation for renal replacement therapy is increasingly used, particularly in acute kidney injury...

When a patient aggressively receives treatment and looks forward to returning home, the prolonging of meaningful life is difficult, even with medical treatment. It is typically very challenging at this juncture for the members of the medical team to fully disclose to the patient the true extent of his / her condition and to recommend the withdrawal of life-support medical treatment. This article describes a nursing care experience with a renal cell carcinoma patient with subcutaneous metastasis. Her pain was induced by an edema and subcutaneous tumor in her lower limbs, which diminished the effectiveness of hemodialysis...

The expression of proinflammatory cytokines/chemokines has been reported in in vitro/ex vivo settings of chronic venous insufficiency (CVI), but the identification of circulating mediators that might be associated with altered hemodynamic forces or might represent innovative biomarkers is still missing. In this study, the circulating levels of 31 cytokines/chemokines involved in inflammatory/angiogenic processes were analysed in (i) CVI patients at baseline before surgical hemody namic correction, (ii) healthy subjects, and (iii) CVI patients after surgery...

Pruritus is an alarming symptom in patients with end-stage renal disease (ESRD) accompanied by sleep disturbances and physical and mental disorders. Although its prevalence is very high among hemodialysis patients (90%), its etiology and its successful treatment have been unconfirmed (Melo N, Elias R, Castro M, Romao G, Abensur H. Pruritus in hemodialysis patients: The problem still remains. Hemodial Int. 2009;13:38-42.). Common pruritus etiologies, such as high parathyroid hormone levels, dialysis inadequacy, and iron deficiency are matters of conflict...

BACKGROUND: Human paraoxonase-1 (PON1) inhibits LDL-oxidation and atherogenesis, and possesses lactonase activity. Decreased PON1 activity was found in hemodialyzed and renal transplanted patients. Cystatin C plays a protective role in atherosclerosis, and is a new, sensitive marker of renal function. The relationship between these two markers in renal failure has not been investigated. AIMS: The goal of this study was to clarify the relationship between PON1 activity, cystatin C and homocysteine in chronic renal failure...

BACKGROUND AND OBJECTIVE: Chronic hemodialyzed patients have a low level of aerobic capacity, caused by the pathologies concomitant to renal insufficiency, according with a low level of physical activity. One of the factors that would contribute to this level of aerobic capacity is the L-carnitine deficit on skeletal muscle. However, the value of the supplementation of L-carnitine to improve the physical fitness has been controversial. The objective of this work was to evaluate the effect of the administration of L-carnitine on VO2 max in hemodialyzed patients...
