In patients with broad QRS complexes on electrocardiogram (ECG), the delayed electrical activation of the left heart chamber will cause abnormal contraction.This has been shown to be possible to treat by a special pacemaker treatment which includes pacing of the left heart chamber (= CRT treatment). In this study the researchers will investigate the effect of acute CRT treatment in the early phase after open heart surgery.
Renal blood flow is inversely related to obstruction. We propose that this imaging will be as effective as the diuretic renogram in the functional diagnosis of obstruction. Furthermore, dynamic contrast CT scanning may also add anatomic information necessary for the surgical treatment.
The purpose of this study is to define the safety profile of rituximab given intrathecally in lymphomatous meningitis related to CD20+ non-Hodgkin's lymphomas.
Obstructive sleep apnea (OSA) is a medical problem whose importance is increasing in recognition and awareness. The National Commission on Sleep Disorders estimates that 15 million Americans have OSA, many of whom remain undiagnosed (24). OSA is associated with the development of hypertension and other cardiovascular diseases (1,2). Patients with OSA, like those with congestive heart failure, hypertension, hypercholesterolemia and diabetes, exhibit impaired EDV (25-32). OSA is also associated with impairments in endothelium-dependent cerebral blood flow responses, which may be a risk factor for stroke (33). Impaired EDV is a result of reduced production or inadequate action of nitric oxide. Since EDV worsens with disease progression and improves with disease treatment, it serves as a prognostic marker of vascular function (34-37). In OSA, hypoxia and neurohumoral disturbances increase generation of reactive oxygen species (ROS) that neutralize nitric oxide and impair endothelium-dependent responses (9,10,38). One source of ROS in endothelial cells is the enzyme xanthine oxidase (38). XO is an enzyme present in the vascular endothelium that significantly contributes to generation of ROS in congestive heart failure, hypercholesterolemia and diabetes (13-17). Inhibition of XO improves endothelium-dependent resistance vessel responses in these populations (13-17), but it is unknown if XO significantly contributes to oxidative stress and endothelial dysfunction in OSA. The central hypothesis of this application is that inhibition of XO with allopurinol will reduce oxidative stress and generation of ROS, thereby improving nitric oxide bioavailability and EDV in OSA. Our hypothesis has been formulated on the basis that patients with OSA experience repeated hypoxemia that increases activity of XO and other enzymes, thus increasing the generation of ROS that negatively impact EDV. Hypoxia is detrimental to vascular homeostasis since it increases generation of ROS through direct mechanisms and via activation of XO.
The Total Parenteral Nutrition (TPN)received as part of your routine burn care has optimal levels of protein and sugar, however the best mixture of amino acids for a patient with burn wounds is not yet known. Amino acids occur naturally in the body and the food we eat. The body combines amino acids to make protein. It uses the proteins to do things such as heal wounds, fight infection, and provide energy. We are studying if the body's use of protein is increased after receiving TPN containing the amino acid called glutamine. We hope to learn the best composition of TPN so that the body can more efficiently repair wounded tissues and recover earlier from an acute burn injury.
This study will evaluate how effective mood stabilizers are in the treatment of bipolar disorder with comorbid alcoholism
The principle objective of the trial is to compare rosiglitazone to gliclazide in patients with type 2 diabetes mellitus and chronic stable angina to see how the subjects' angina status changes. Angina status will be measured via exercise tolerance testing, 24-hour ECG testing and angina quality of life questionnaire.
RATIONALE: Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase II trial is studying how well vaccine therapy works in treating patients with stage IIIB or stage IV breast cancer in remission.
RATIONALE: Vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by stopping blood flow to the tumor. Octreotide may help control symptoms, such as diarrhea, caused by the tumor. Giving vatalanib together with octreotide may be an effective treatment for neuroendocrine tumors. PURPOSE: This phase II trial is studying how well giving vatalanib together with octreotide works in treating patients with progressive neuroendocrine tumors.
RATIONALE: Drugs used in chemotherapy, such as fluorouracil and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving drugs directly into the arteries around the tumor may kill more tumor cells. Giving chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether surgery and hepatic arterial chemotherapy are more effective than surgery alone in treating patients with liver cancer that has spread to the portal vein. PURPOSE: This randomized phase III trial is studying surgery and hepatic arterial chemotherapy to see how well they work compared to surgery alone in treating patients with liver cancer that has spread to the portal vein.
