NCT01097330
Implantable Cardioverter Defibrillators (ICDs) provide a shock or pacing therapy to bring back a normal heart beat when a patient experiences a dangerous abnormal heart rhythm such as ventricular tachycardia (VT). ICDs are very successful in bringing back a normal heart beat when VT occurs, but they do not prevent further dangerous heart rhythms from occurring. This study is designed to determine the best way to manage patients who have an ICD and who continue to have episodes of VT. There are two methods for treatment the VT: 1) Ablation, and 2) Medication. An ablation procedure involves placing a flexible catheter (insulated wire) in the groin area and threading it into the heart. After the doctor has located the affected area responsible for the VT, radiofrequency energy is delivered by the power generator through the catheter to the inside of the heart. The radiofrequency energy ablates (burns) a small area of the heart tissue thought to cause the VT. A medication called Amiodarone is an "anti-arrhythmic" prescribed to prevent abnormal heart rhythms from recurring. The purpose of this study is to compare these two different methods for treating VT. Treatment with ablation and amiodarone are both considered the standard of care for patients with VT but they have not been compared directly in a study like this before.
NCT03655301
The purpose of this study is to learn about a drug-drug interaction. When two medications are taken together at the same time, one medication may change the activity of the other medication in the body - this is called a drug-drug interaction. This study is looking at the effect the Bayer study drug, copanlisib, has on metformin, a commonly used medication to treat diabetes. During the study, blood and urine samples will be collected and analyzed to learn about pharmacokinetics (how copanlisib changes metformin levels in the body) and pharmacodynamics (the effect metformin has on the body when taken together with copanlisib) when someone takes both copanlisib and metformin together.
NCT04241081
Investigating the effects of interrupting various lengths of prolonged sitting with bike sprints on post prandial lipemia the next day. We will conduct three trials, one control, one with two-hour sitting intervals (total of 4 bouts of bike sprints) and one with 6-hour sitting intervals I total of two bouts of bike sprints). A milkshake high fat tolerance test will be conducted the next day and whole body fat oxidation as well as triglyceride area under the curve will be measured every hour for the duration of the 6-hour test.
NCT01297322
The objective of this trial is to demonstrate the safety and effectiveness of the Cardiva VASCADE™ Vascular Closure System (VCS) in sealing femoral arterial access sites. Hypothesis: The Cardiva VASCADE™ VCS provides times to hemostasis (TTH) and time to ambulation (TTA) results that are less than manual compression by a clinically meaningful and statistically significant margin. The rate of major access site-related complications with the Cardiva VASCADE™ VCS is non-inferior to the major complication rates of manual compression for sealing femoral arterial access sites.
NCT02043574
Strokes are very common in the United States and occur more in the elderly. The number of strokes is likely to double in the next 50 years. Many stroke survivors are sedentary and have a poor dietary intake, which results in abnormalities in fuel utilization (eg carbohydrate versus fat). This study will examine the effects of dietary modification and treadmill training on fuel utilization and physical function. We will study skeletal muscle oxidative stress in chronic stroke patients and the ability to employ dietary modification and exercise training to reverse these abnormalities in this ethnically diverse population.
NCT00754013
The purpose of this study is to determine the efficacy and safety of donepezil hydrochloride (Aricept) in the treatment of cognitive dysfunction shown by children with Down syndrome, aged 6 to 10 years.
NCT01038557
The purpose of this study is to look at red blood cell (RBC) transfusions in trauma patients and evaluate for any differences between the age of the RBCs and how they were stored. The investigators will specifically look for the following differences between study groups: 1. the transfused red blood cells' ability to delivery oxygen to the tissues 2. differences in biochemical markers in subjects and units transfused, and 3. how the subject's internal organs are working and if they develop any infections
NCT02515097
This study is to evaluate the safety and efficacy of a topical lotion when applied once daily to adult participants with moderate to severe plaque psoriasis (defined as an Investigator's Global Assessment \[IGA\] score of 3 or 4).
NCT02383212

NCT03337477
The study is designed to determine if ZS 10g administered up to three times over 10h added to insulin and glucose in patients presenting with hyperkalemia will prove tolerable and efficacious. Patients will receive ZS or Placebo on top of standard of care treatment with insulin and glucose.
NCT02210689
A multi-center, double-blind, randomized, placebo controlled, parallel-group study, comparing Clindamycin phosphate vaginal cream 2% (Watson Laboratories, Inc.) to Clindesse® (Ther-Rx™, Clindamyin Phosphate Vaginal Cream 2%) and both active treatments to a placebo control in the treatment of bacterial vaginosis in non-pregnant women.
NCT02220842
This open-label, multicenter, global study is designed to assess the safety, tolerability, preliminary efficacy, and pharmacokinetics of intravenous atezolizumab (MPDL3280A) and obinutuzumab in participants with refractory or relapsed follicular lymphoma (FL) or atezolizumab and obinutuzumab or tazemetostat administered in participants with refractory or relapsed diffuse large B-cell lymphoma (DLBCL). The anticipated duration of this study is approximately 4.5 years.
NCT01065636
Obesity causes frailty in obese older adults by exacerbating the age-related decline in physical function. However, appropriate management of obesity in older adults is controversial. Weight loss without exercise could worsen frailty by accelerating the usual age-related decline in muscle and bone mass that leads to sarcopenia and osteopenia, respectively. Because of the important problem of frailty in obese older adults, it is important to determine the most efficacious approach in reducing, or even reversing frailty in this population. The primary objective of this proposal is to evaluate which distinct type of physical exercise (resistance, aerobic, or combined resistance + aerobic) is most efficacious in preventing the weight-loss-induced reduction in muscle and bone mass and reversing frailty in obese older adults.
NCT03226444
The objective of this study is to evaluate the efficacy and safety of two strengths of Lacripep™ ophthalmic solution versus placebo administered three times daily for four weeks in subjects with a diagnosis of Dry Eye associated with documented Primary Sjögren's Syndrome
NCT02508948
In order to examine the current endotracheal intubation practice among critically ill patients, a prospective observational multicenter study of adult critically ill patients was conducted from July 2015 to January 2017 involving 20 ICUs. In this study, the primary aim was to describe, through a prospective observational multicenter study, the current intubation practice of adult critically ill patients undergoing endotracheal intubations with a focus on deriving and validating a prediction model for both immediate airway and hemodynamic complications.
NCT03096314
Vitamin D deficiency is a common, potentially reversible contributor to morbidity and mortality among critically ill patients. We conducted a randomized, double-blind, placebo-controlled, phase 3 trial of early vitamin D3 supplementation in critically ill, vitamin D-deficient patients who were at high risk for death. Patients screened as vitamin D deficient (\<20 ng/mL) were randomized. Randomization occurred within 12 hours after the decision to admit the patient to an intensive care unit. Eligible patients received a single enteral dose of 540,000 IU of vitamin D3 or matched placebo. The primary end point was 90-day all-cause, all-location mortality.

NCT00602836
RATIONALE: Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Drugs used in chemotherapy, such as pentostatin and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Lenalidomide may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving rituximab together with combination chemotherapy and lenalidomide may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving rituximab together with pentostatin, cyclophosphamide, and lenalidomide works in treating patients with previously untreated B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma.
NCT00342316
This study compares overall survival between patients with acute myeloid leukemia, who are in complete remission following initial treatment with chemotherapy and whose remission is maintained either with a transplantation of stem cells obtained from a sibling or unrelated donor or with standard treatment, which is additional chemotherapy. The study hypothesis is that the group transplanted with stem cells from a donor will have a superior survival compared with patients treated with standard of care.
