Filter by:Newly formed dialysis fistulae can often fail, and failure is usually due to narrowing of the blood vessels. Methods of detecting narrowing are available and, more importantly, can detect narrowings before a fistula fails. It is not known whether treating these narrowings will actually improve fistula survival or if the majority can be left alone. we wish to see if we can detect such narrowings with ultrasound scanning and if early detection and treatment improves patient outcomes.
The purpose of this study is to determine whether the heparin-coated dialysis filter is superior to a conventional filter during hemodialysis in twelve stable, chronic hemodialysis (HD) patients. The antithrombogenic properties of the heparin-coated dialysis filter and of the conventional filter will be compared by means of statistical tests.
This phase I trial studies the side effects and the best dose of veliparib when given together with paclitaxel and carboplatin in treating patients with solid tumors that are metastatic or cannot be removed by surgery and liver or kidney dysfunction. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving veliparib together with paclitaxel and carboplatin may kill more tumor cells.
Patients with cirrhosis present an increased susceptibility to bacterial infections. Spontaneous bacterial peritonitis (SBP) is the most frequent infection and induces severe circulatory dysfunction associated with renal failure in about 30% of cases. Renal failure is a reliable surrogate marker of in-hospital mortality in patients with SBP or with non-SBP infections. Albumin, as an adjuvant to antibiotherapy reduces significantly the rate of renal failure, in-hospital mortality, and overall mortality (Sort P, et al. NEJM 1999). However, little is known regarding the effect of albumin administration in patients with non-SBP infections. Two recent prospective studies demonstrated that non-SBP infections are associated with impairment of the effective circulating volume and precipitate renal failure whatever the presence of ascites. The aim of this randomized clinical trial is to evaluate the effects of albumin, associated with appropriate antibiotic therapy, on occurrence or deterioration of renal failure and survival in septic (SIRS criteria required) cirrhotic patients with non-SBP infections and presenting with a Child-Pugh score > 8.
Recently there is increasing reports of NEPHROGENIIC SYSTEMIC FIBROSIS(NSF) in patients with severe renal failure mainly in patients under dialysis in whom gadollinum is being used. The investigators will evaluate the prevalence and severity of NSF in patients with different degree of renal failure whom underwent imaging with Gadolinum.
This study will investigate whether inspiratory muscle training in patients with end stage renal failure can improve strength and function.
Remote ischemic preconditioning (RIPC) occurs when a tissue (ex. heart) becomes less vulnerable to an ischemic insult if a remote tissue (ex. arm) has had previous exposure to a period of ischemia and reperfusion. A beneficial effect of RIPC has been demonstrated in several randomized studies in patients undergoing cardiac and vascular surgery, as well as interventional cardiac procedures such as angioplasty. They have shown improvements in cardiac, renal, neurologic and respiratory function. Most have focused on surrogate outcomes, such as biochemical markers of cardiac and renal function in low-risk patients. No trials have investigated only high-risk patients or been designed to detect clinical outcomes. This study is a randomized-controlled trial powered to detect clinical events in a high-risk cohort undergoing cardiovascular surgery. Patients will be randomized to RIPC (exposed to cycles of inflation of a blood pressure cuff on the upper arm prior to undergoing surgery) or control (no ischemic stimulus). The investigators hypothesize this population will demonstrate lower rates of adverse ischemic events. The investigators also intend to sample biochemical markers to better elucidate the mechanism of RIPC and generate hypotheses for future studies and interventions. Post-operatively the investigators will monitor for adverse clinical outcomes including cardiac, renal, pulmonary and neurologic injury. RIPC is simple, inexpensive and easily reproducible and there have been no reports of adverse consequences. Post-operative ischemic events such as stroke, myocardial infarction, cardiac, renal and respiratory failure affect patient survival and quality of life, and represent a sizeable financial burden to health care. If beneficial effects of RIPC are demonstrated, it will be widely applicable to the entire population of cardiac and vascular patients resulting in a widely-implemented change in practice.
RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarkers in blood and tumor tissue samples from patients with Wilms tumor.
Primary: • To validate the initial dosing recommendations for newly diagnosed MM (Mutiple Myeloma) patients with various degrees of renal failure using pharmacokinetic studies Secondary: - To evaluate the safety of lenalidomide and dexamethasone as induction therapy in newly-diagnosed MM (Multiple Myeloma) patients with renal dysfunction using modified dosing guidelines - To evaluate clinical response of lenalidomide and dexamethasone after 4 cycles using the modified dosing guidelines - To evaluate the ability to collect stem cells after 4 cycles of lenalidomide and dexamethasone induction therapy in MM (Multiple Myeloma) patients with renal failure
To evaluate the efficacy of honey as a post surgical exit site care process to promote healing and prevent infectious bacterial colonization of newly created exit sites. It has been shown in the medical literature that honey has properties that are conducive to healing and the prevention of infection. In one study it was demonstrated that in urethral injury in the rat treated with honey the injury healed with none of the usual formation of fibrous tissue seen in such healing processes, that there was no reduction in the luminal diameter usually seen, and that the cells lining the urethra were uncompromised in any way, i.e. totally normal and healthy. We feel that if an exit site can be healed quickly with good normal tissue being developed that the patient will have a much better chance to keep that exit healthy reducing time, cost, and disruption of lifestyle. Other positive aspects of honey are it has the low pH required for good healthy tissue healing, it works in the presence of wound fluids, and it has never been shown to produce a resistant bacterial strain.
