Filter by:Patients are admitted to the critical care unit of the hospital because of medical conditions that have a high likelihood of causing severe problems with blood flow, breathing, or brain function. These conditions also have a high likelihood of causing death. Approximately 10 to 15% of all critically ill patients die in hospital. A large amount of scientific evidence suggests that a substantial proportion of these deaths is due to a combination of blot clotting and inflammation in the blood vessels. Statins are drugs that interfere with cholesterol and fat metabolism. Cholesterol and fat in the blood are associated with blood clotting and inflammation in the blood vessels. Statins are known to be very beneficial in improving the survival after heart attacks, and in preventing heart attacks. The question that VASTVALUS asks is: do statins improve survival among all critically ill patients? In VASTVALUS, we will concentrate on patients that do not currently require a statin because of their medical condition e.g. after a heart attack, but we are concerned with the rest of the critically ill. In VASTVALUS, participating patients will receive either atorvastatin 80 mg daily or a placebo. Atorvastatin is a statin with a well-established record of safety and effectiveness. A placebo has no known medical activity. We will follow all patients in VASTVALUS to determine whether atorvastatin has any effect on the occurrence of death, stroke, heart attack, or kidney failure among the critically ill. Results from VASTVALUS will be shared with the medical community after the study is completed. As with all clinical trials, patients in VASTVALUS participate of their own choice, and can change their mind at any time.
Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. When your kidneys fail, harmful wastes build up in your body and your body may retain excess fluid. When this happens, you need treatment to replace the work of your failed kidneys. This may be with a dialysis machine using haemodialysis or with fluid in the abdomen or peritoneal dialysis. In peritoneal dialysis, a tube called a catheter is put in the abdomen wall and used to fill your abdomen with a cleansing liquid called dialysis solution. The walls of your abdominal cavity are lined with a membrane called the peritoneum, which allows waste products and extra fluid to pass from your blood into the dialysis solution. These wastes and fluid are removed from the body when the dialysis fluid is drained and replaced with a fresh solution. The tubes or catheters used to exchange the fluid are currently positioned using a general anaesthetic (with the patient awake) and an operation with a cut under the belly button. Newer techniques using local anaesthetic (with the patient awake and the area numbed) and requiring only a small cut in the skin have been used. No one has ever directly compared the two techniques. The investigators aim is to perform a direct comparison between the two techniques to look at the complications and time required for surgery and length of hospital stay required. The investigators will also look at the patients satisfaction and pain scores with each technique to help gather evidence as to which is likely to be the best technique to use from now on.
Consecutive living-kidney donor candidates (n=100) will be recruited after being accepted for donation according to official guidelines. An assessment of salt sensitivity, 11 beta HSD activity, 24 hour blood pressure, urine collection and physical exam will be performed prior nephrectomy and 14, 52, 156, 208 days post-nephrectomy.
The pharmacokinetics of sodium thiosulfate in humans with different degrees of renal failure and in healthy volunteers will be after two single shot applications.
Introduction: Narrowing of the draining vein occurs in >50% of hemodialysis fistula and left untreated will lead to loss of access. The narrowing is due to excessive growth of tissue in the vessel wall (intimal hyperplasia). The standard treatment is balloon dilatation. However, narrowing will inevitably recur in 2-3 months hence requiring further dilatation. Intimal hyperplasia also occurs in the heart and leg circulation. The drug paclitaxel has been used with great success in preventing intimal hyperplasia in these vessels following balloon dilatation. Administer locally, paclitaxel inhibits excess tissue growth in the vessel wall. The investigators believe that this drug will have similar effect in hemodialysis access.. Objective: To assess the effect of paclitaxel in hemodialysis access with narrowing. Paclitaxel is delivered by a paclitaxel-coated balloon. This balloon dilates the narrow segment and simultaneously delivers paclitaxel to the vessel wall. Methodology: Patients with narrowed hemodialysis access are dilated with the paclitaxel-coated balloon or conventional balloon in randomized manner. The patency of the two groups are evaluated and compared at 6 months follow-up. Potential benefit: Decrease number of balloon dilatations and hence hospital admissions, improve dialysis fistula function, and decrease overall economic cost.
Peri-operative fluid therapy is a controversial area with few randomized trials to guide practice. Fluid management has a significant influence on outcome following surgery. Yet practically, fluid prescription practice during this period is sub-optimal, resulting in avoidable iatrogenic complications. Several studies have assessed the effect of a 'liberal' vs. a 'restrictive' perioperative fluid regimen on post-operative outcome. However, most of these studies have focused primarily on intra-operative fluid management, whereas postoperative strategies have been less well defined, even though the immediate postoperative period is of critical importance to the patient's recovery. Moreover, whereas intra-operative fluid administration is monitored by the anesthesiologist, postoperatively it is less supervised and may result in excess or lack of intravenous (IV) fluids. Therefore, fluid management audit at the post-anesthesia care unit (PACU) is of paramount importance for patient healthcare. The objective of this study is to follow and report the current practice of fluid administration in the PACU of Tel Aviv Sourasky Medical Center, for an extended period of time as a first step towards establishing evidence-based guidelines for postoperative fluid management.
Chronic utilization of bio-incompatible peritoneal dialysis (PD) solution has been implicated as a cause of progressive loss of peritoneal permeability and recurrent fluid overload in PD patients. Previous studies show that PD solution with neutral pH and low GDP resulted in a superior profile of PD effluent mesothelial cell marker and a lower degree of systemic inflammation as compared to conventional PD solution. The investigators propose a prospective randomized control study to compare the arterial stiffness, nutrition and body fluid status between PD patients treated with conventional solution and those with neutral pH low GDP solution. The investigators plan to study 100 new PD patients. They will be randomized to be treated with neutral pH low GDP solution or conventional solution. All patients will be followed for 52 weeks. In addition to routine clinical measurements, the investigators will measure their body water composition by bioimpedance spectroscopic method, arterial pulse wave velocity by pressure transduction method, as well as radiographic parameters of intravascular volume status, based on the routine chest radiograph. The study would help to define the clinical benefit of biocompatible PD solution.

The aim of this study is to evaluate the effect of prolonged administration of albumin and midodrine on the prevention of complications (renal failure, sepsis, hemorrhage, hepatic encephalopathy and hyponatremia) in patients with cirrhosis in the waiting list for liver transplantation. One hundred and ninety four patients with cirrhosis and awaiting a liver transplantation will include in the study. Patients will be randomized to receive albumin and midodrine (treatment group) or administration of placebo (saline for albumine) and tablets with excipients without midodrine (control group). Patients will be followed-up during 12th months. In the treatment group albumin will be given at a dose of 40g every 15 days and midodrine 5mg tid, in addition with lactitol (conventional doses) and the specific treatment that patients require by cirrhosis. The group control will receive placebo in the same way than the treatment group in addition with lactitol and the specific treatment that they require by their disease. In all the patients liver and renal function test, hormones determination (renin, aldosterone, noradrenaline), and cytokines will be determined in basal conditions. All these determinations will be repeated at month 1st,3rd, 6th and 12th months. Before the inclusion in the study neuropsychological test and critical flicker test will be performed to diagnose minimum EH. These tests will be repeated at 3rd, 6th and 12th months. All the determinations will be repeated at any time that the patients develop any complication considered as an end point. In baseline conditions and at 3rd and 6th months a questionnaire of quality of life (SF36) will be performed. During a year of follow-up the number of paracentesis that patients require, the incidence of renal failure and EH and their relationship with hormonal activity and cytokine levels, free transplant survival and quality of life will be recorded.
This is 2-armed parallel group, prospective, randomized, open-label, multicenter Phase 3 controlled trial to establish the efficacy and safety of conversion from maintenance immunosuppressive therapy with Prograf® capsules (tacrolimus, Astellas Pharma US, Inc., Deerfield, IL) twice daily to maintenance immunotherapy with LCP Tacro™ tablets (tacrolimus, LifeCycle Pharma A/S, Hoersholm, Denmark) once daily for the prevention of acute allograft rejection in stable adult kidney transplant patients. Patients on a stable dose of Prograf® will be randomly assigned to be converted from Prograf® twice daily to LCP Tacro™ once daily or to remain on maintenance therapy with Prograf® twice daily. Patients entering the study will be treated with assigned study drug and followed for one year for patient survival and the incidence of graft rejection or graft loss.
