NCT01824082
When a limb is traumatically severed, pain perceived in the part of the body that no longer exists often develops. This is called "phantom limb" pain, and is different from "stump" pain, which is pain within the part of the limb that remains intact. Unfortunately, phantom pain resolves in only 16% of people, with the rest experiencing this pain for the remainder of the lives. There is currently no reliable treatment for phantom limb pain. The exact reason that phantom limb pain occurs is unclear, but when a nerve is cut-as happens with a traumatic amputation-changes occur in the brain and spinal cord that actually worsen with increasing phantom pain. These abnormal changes may often be corrected by putting local anesthetic-termed a "peripheral nerve block"-on the injured nerve, keeping any "bad signals" from reaching the brain, with resolution of the phantom limb pain. However, when the nerve block ends after a few hours, the phantom pain returns. But, this demonstrates that the brain abnormalities-and phantom pain-that occur with an amputation may be dependent upon the "bad" signals being sent from the injured nerve(s), suggesting that a very long peripheral nerve block-lasting many days rather than hours-may permanently reverse the abnormal changes in the brain, and provide lasting relief from phantom pain. Until recently, extending a peripheral nerve block beyond 16 hours was unrealistic. However, a treatment option called a "continuous peripheral nerve block" is now available. This technique involves the placement of a tiny tube-smaller than a piece of spaghetti-through the skin and next to the nerves supplying the amputated limb. The tiny tube may be placed with minimal discomfort in about 15 minutes. Numbing medicine called local anesthetic is then infused through the tube, blocking any signals that the injured nerve sends to the spinal cord and brain. Using a small, portable infusion pump, this prolonged nerve block may be provided in individuals' own homes. The ultimate objective of the proposed research study is to determine if a 6-day continuous peripheral nerve block provided at home is an effective treatment for persistent phantom limb pain following a traumatic limb amputation. The primary hypothesis (what the researchers predict) is that phantom limb pain intensity will be significantly decreased 4 weeks following treatment with a 6-day continuous peripheral nerve block.
NCT00068159
This study will examine the effect of iron buildup in the hearts of patients with hereditary hemochromatosis (HH), a genetic disease that causes the body to accumulate excess amounts of iron. The excess iron can damage the heart, liver, pancreas, skin, and joints. Generally, early treatment with phlebotomy (periodic removal of a unit of blood), and in some cases chelation (using a drug to remove iron from the body) slows down organ damage in HH patients. This study will try to elucidate the effect of iron buildup in the heart and determine if phlebotomy and chelation help keep the heart healthy. Patients with HH and healthy volunteers 21 years of age and older may be eligible for this study. (Normal volunteers will provide normal values of heart function that will be used to verify abnormalities detected in HH patients.) Patients must have a gene abnormality of Hfe gene Cys282Try homozygote. They may or may not be receiving treatment for HH and they must have no heart symptoms or serious organ damage due to HH. Candidates will be screened with a medical history and physical examination, blood tests, electrocardiogram (EKG), Holter EKG (24-hour EKG monitoring, see description below), and chest x-ray. Participants will undergo the following tests and procedures over 2 to 5 days: * Exercise test: The participant exercises on a treadmill while wearing a mouthpiece, which is used to measure how much oxygen is used. Electrodes placed on the chest and arms monitor the heartbeat during the test. * Echocardiography: This ultrasound test uses sound waves to take pictures. A small probe is held against the chest to allow a technician to take pictures of the heart and assess its function. A drug called Optison may be injected in an arm vein if needed to enhance the ultrasound images. * Exercise stress echocardiography: The participant exercises on a stationary bike while heart function is measured with an echocardiogram, EKG, and blood pressure cuff. * 24-hour Holter EKG: The participant wears a small machine that records heart rhythm continuously for 24 hours. The recorder is connected by cables to electrodes placed on the chest. * Magnetic resonance imaging: This test uses a magnetic field and radio waves to obtain detailed images of the heart and blood vessels. The participant lies flat on a table that slides inside the scanner, which is a large hollow tube. All tests are performed once in normal volunteers and in patients who have received standard treatment for HH. Untreated patients repeat the tests 6 months after beginning phlebotomy or chelation. Additional time points for these tests might be added if further evaluation is needed.

NCT02728102
The study is designed as a Phase II, multicenter trial of vaccination with Dendritic cell/myeloma fusions with granulocyte macrophage colony-stimulating factor (GM-CSF) adjuvant plus lenalidomide maintenance therapy versus maintenance therapy alone or with GM-CSF following autologous transplant as part of upfront treatment of multiple myeloma (MM). It is hypothesized that the dendritic cell myeloma vaccine will result in improved response in patients with multiple myeloma after autologous Hematopoietic Cell Transplant (HCT).
NCT03471247
Patients who survive critical illness usually experience long-lasting physical and psychological impairments, which are often debilitating. Rehabilitation interventions started in the ICU may reduce this morbidity. In-bed cycling, which uses a special bicycle that attaches to the hospital bed, allows critically ill patients who are mechanically ventilated (MV) to gently exercise their legs while in the ICU. The main goal of this study is to determine whether critically ill MV adults recover faster if they receive early in-bed cycling than if they do not. Another objective is to determine whether in-bed cycling is a cost-effective intervention. 360 patients admitted to the ICU and receiving MV will be enrolled in the study. Following informed consent, patients will be randomized to either (1) early in-bed cycling and routine physiotherapy or (2) routine physiotherapy alone. Patients' strength and physical function will be measured throughout the study. If early in-bed cycling during critical illness improves short-term physical and functional outcomes, it could accelerate recovery and reduce long-term disability in ICU survivors.
NCT05161897
The overall aim of this feasibility study is to conduct a randomized, controlled intervention providing adults with prediabetes either an individualized nutrition therapy (INT) intervention that contains individualized dietary goal-setting components, the goal being to improve blood glucose, reduce CVD risk factors, and therefore postpone the onset of diabetes and related cardiovascular disease, or standard-of-care generalized dietary recommendation (SOC). The hypothesis is that the INT arm will experience greater benefits in some or all of the following primary outcome variables: improvement in postprandial blood glucose, oral glucose tolerance test, fasting insulin, and calculated insulin sensitivity (HOMA) in individuals with prediabetes. Secondary outcome variables are improved markers of inflammation, antioxidant status, blood lipids, blood pressure, and endothelial function.

NCT03969225
A functioning vascular access provides a lifeline for patients requiring haemodialysis but vascular access dysfunction remains one of the leading causes of excessive morbidity, mortality and healthcare costs in this group. Despite increasing numbers of vascular access trials, successful interventions to improve vascular access function have been sparse and compromised by highly variable, often selectively reported outcome measures of limited relevance to patients and health professionals. Through engagement of all relevant stakeholders including patients and caregivers, vascular access function, defined by the need for interventions to enable and maintain the use of a vascular access for haemodialysis, has been identified as one of the most critically important outcome measures for trials in haemodialysis. This prospective, multi-centre, multinational validation study aims to assess the accuracy and feasibility of measuring vascular access function part of routine clinical practice and across different clinical settings to ensure successful global implementation of this core outcome measure in future trials in haemodialysis.
