Emotional distress and health-related quality of life in patients on hemodialysis: the clinical value of COOP-WONCA charts.
A significant percentage of patients on hemodialysis (HD) present with affective disorders such as anxiety and/or depression. The purpose of this study was to explore adaptive mixed affective disorders of patients on HD and to analyze the clinical value of a brief health-related quality-of-life (HRQoL) instrument, the COOP-WONCA charts, in our population of HD patient. ⋯ A high percentage of patients on HD present with mixed emotional disorders (anxiety and/or depression); a good correlation is observed between HRQoL and the levels of anxiety and depression in these patients; and measuring HRQoL with the COOP-WONCA charts may help diagnose such problems.

ReviewAcute renal failure in critically ill patients: indications for and choice of extracorporeal treatment.
The prescription of extracorporeal therapy for patients with acute renal failure involves many options: dialysis sessions may be intermittent or continuous, semicontinuous or slow-extended, with controversial indications still to be defined also depending on technical and logistic issues and related to the multidisciplinary cooperation needed in the management of critically ill patients. All efforts to evaluate extracorporeal treatments in these patients must be targeted not only towards supporting renal function, but towards all functional and metabolic derangements that can result from artificial blood purification, in any way achievable.

Randomized Controlled Trial Comparative StudyComparison of the diuretic effect of furosemide mixed with human albumin or fresh frozen plasma for patients with hypoalbuminemia in the intensive care unit.
Diuretics are commonly used in the intensive care unit (ICU) for patients with fluid over-loading. Hypoalbuminemia is a major cause of diuretic resistance. Albumin mixed with furosemide can promote diuresis and sodium excretion in patients with hypoalbuminemia. The purpose of this study is to compare the diuretic effect of furosemide (FU) mixed with human albumin (HA) or fresh frozen plasma (FFP) in ICU patients with hy-poalbuminemia. ⋯ In ICU patients, 60 mg FU mixed with HA or FFP has a similar diuretic effect in patients with CCr >20 ml/min. FFP is an effective alternative choice for improving diuresis for ICU patients with hypoalbuminemia. In patients with CCr < or = 20 ml/min, albumin mixed with 60 mg FU has a superior diuretic effect compared with FFP mixed with FU.

ReviewDo central venous catheters have advantages over arteriovenous fistulas or grafts?
Central venous accesses have become an integral component of vascular access procedures for hemodialysis. Although the DOQI guidelines recommend that less than 10% of chronic hemodialysis patients should be maintained on catheters, in some countries higher prevalences are reported, as in the United States and the United Kingdom (18% and 24%, respectively, according to the DOPPS). The native arteriovenous fistulas are still the best suited accesses for hemodialysis. ⋯ In a matched comparison between Tesio twin catheters and Dialock ports (37 vs. 35, respectively), followed for a 2 year period, no significant differences emerged as regards bacteremia incidence, 0.58/1,000 catheter-days in the Tesio catheter group vs. 0.9/1000 catheter-days in the subcutaneous port group, p=0.12; thrombolytic agents needed, 4.5% vs 4.3% of dialysis sessions; or access failure with removal of the device, 8.1% vs 14.2%, p=0.4. The longer duration of antibiotic therapy in the Tesio group (24.6 vs 14.3 days, p=0.006) was due to the higher incidence of cutaneous infectious episodes (3.8 vs 0.16/1,000 catheter-days). In conclusion, although central venous catheter is the vascular access of last choice, in particular cases it can be a useful alternative, provided that strict protocols for nursing care and proper catheter management are implemented in every center.

A well-functioning vascular access for hemodialysis plays a key role in the quality of life and clinical outcome of dialysis patients. A vascular access for dialysis is considered to be adequate when it provides a blood flow of at least 250 ml/min in the standard dialysis and up to 350-400 ml/min in the high-efficiency dialysis. So far, Cimino-Brescia arterio-venous fistula still remains the gold standard among the available vascular accesses. ⋯ The most important complications of vascular access are stenoses, thromboses, infections. Infections, more frequent in synthetic vascular access than in native fistulas, are responsible for the increase in patients' morbidity and, consequently, in public health costs. An integrated multi-professional approach of vascular access, involving nephrologists, vascular surgeons, interventional radiologists, and trained dialysis nurses should be implemented in order to early detect vascular access complications and failure.
