NCT00437060
This clinical trial is looking at brain function in young patients receiving methotrexate for acute lymphoblastic leukemia. Learning about the long-term effects of methotrexate on brain function may help doctors plan cancer treatment.
NCT00335556
This phase II trial is studying how well combination chemotherapy, radiation therapy, and/or surgery work in treating patients with high-risk kidney tumors. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
NCT01853332
The purpose of this study is to determine the effects of individual characteristics, life stresses, and relationships over time on psychosocial outcomes (e.g. marriage, parenting, work) and physical health
NCT01414010
The purpose of this study is to compare and contrast the effects of a prebiotic (Trametes Versicolor), a probiotic (Saccharomyces boulardii) and an antibiotic (amoxicillin) on the gut microbiota of healthy volunteers. It is expected that treatment will result in the rapid and reproducible alterations in fecal microbiota that will spontaneously reverse in the weeks after treatment is discontinued.
NCT00931801
The purpose of this Phase IV pilot study is to evaluate the safety, tolerability, and satisfaction of a nucleoside analog reverse-transcriptase inhibitors (NRTI)sparing regimen for participants fully suppressed on an atazanavir/ritonavir based highly active antiretroviral therapy (HAART)regimen plus emtricitabine/tenofovir (Truvada). Several pharmacologic factors support this concept including the favorable drug interaction between atazanavir and raltegravir. Participants will be randomized to either continue on their current regimen or one of two study arms (atazanavir 300mg plus ritonavir 100mg daily plus raltegravir 400mg twice daily or atazanavir 300mg twice daily plus raltegravir 400mg twice daily). Participants will be followed for 48 weeks for safety, tolerability, and satisfaction. After baseline, the participants will have six clinic visits for evaluation and labs.
NCT01000155
Sickle Cell Disease (SCD) is a hereditary anemia that causes the red blood cells to change their shape from a round and doughnut-like shape to a half-moon/crescent, or sickled shape. People who have SCD have a different type of hemoglobin (protein that carries oxygen). This different type of hemoglobin makes the red blood cells change into a crescent shape under certain conditions. Sickle-shaped cells are a problem because they often get stuck in the blood vessels blocking the flow of blood and can cause inflammation and injury to important areas of the body. All babies are born with hemoglobin called fetal hemoglobin (HbF). Soon after birth, HbF production slows down and another hemoglobin called adult hemoglobin (HbA) is made. Clinical studies have shown that increasing the amount of HbF in the blood may prevent sickling of the red blood cells. Vorinostat has been used in the treatment of cancers and in other research studies and information from those suggests that it may help treat SCD by increasing the amount of HbF in the blood. The purpose of this research study is to determine the effectiveness and safety of vorinostat when used to treat SCD.
NCT01920633

Study participants may withdraw from this study at any time and for any reason.
NCT00106938
The study is being conducted to demonstrate the non-inferiority of carotid artery stenting (CAS) using the Emboshield® Embolic Protection System with the Xact® Carotid Stent System to carotid endarterectomy (CEA) for the treatment of asymptomatic extracranial carotid atherosclerotic disease.
NCT01955889
Persons with Parkinson Disease (PD) face significant declines in function resulting in greater disability. Function can improve through participation in exercise, yet many people with PD are physically inactive. Given that people with PD live long lifespans following diagnosis; it is essential to include routine exercise into their lives over the long-term. Physical therapy is effective in improving function in persons with PD. However, participation in on-going physical therapy indefinitely is not a realistic option due to limited healthcare resources. Interventions using mobile health technologies allow physical therapists to stay connected to patients over time potentially improving their ability to meet the changing needs of patients with PD. Innovative approaches using mobile health technology may improve outcome; however, the effectiveness of different approaches to improve function and reduce disability in PD is unknown. The purpose of this study is to compare the effectiveness of two interventions to improve function and health-related quality of life in 65 people with PD. In one study group, participants receive a home exercise program, in written format, to continue on an independent basis. In the other study group, participants are instructed to continue with an exercise program, in their home, delivered using videos of the exercises on a computer tablet device. This use of mobile-Health technology allows the physical therapist to remotely monitor participants' progress and modify the exercise program to meet the changing needs of each patient. The long-term objective of this research is to determine the most efficient and effective way to improve function that can be widely disseminated to persons with PD.
NCT01754389
This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA has not yet approved bortezomib to treat or prevent graft-versus-host disease. Bortezomib is approved by the FDA to treat other human malignancies. Bortezomib is a drug that has an anti-cancer effect that involves inhibiting cell growth and causing cell death. This drug has been used in other research studies, and information from thos other research studies suggests that bortezomib may help to lower the risk of GVHD after allogeneic stem cell transplantation in patients who have matched unrelated, unmatched related or unrelated donors in this research study. Allogeneic stem cell transplantation is a procedure in which selected blood cells taken from your sibling or unrelated donor are given to you. Lower doses of chemotherapy drugs are given before the donor cells are infused in a process known as reduced-intensity conditioning. Stem cell transplant destroys cancer in two ways: The conditioning regimen destroys cancer cells and teh immune cells from the donor can recognize cancer cells and kill them. A common problem after stem cell transplant is graft-versus-host disease (GVHD). The word "graft" refers to the donor blood cells that you will receive during your transplant. The word "host" refers to the person (in this case, you) receiving the cells. GVHD is a complication of transplantation where the donor graft attacks and damages some of your tissues. GVHD can cause skin rash, intestinal problems such as nausea, vomiting or diarrhea. GVHD may also damage your liver and cause hepatitis or jaundice. GVHD may also increase your risk of infection. After stem cell transplant, all patients receive prophylactic medications against GVHD. In this research study we are studying the safety and effectiveness of preventing GVHD using bortezomib treatment in combination with other drugs versus standard of care prophylaxis (tacrolimus + methotrexate). If you take part in this study, there is a 33% chance you will receive any one of the following GVHD prevention treatments: * tacrolimus + methotrexate (standard of care GVHD prophylaxis) * bortezomib + tacrolimus + methotrexate * bortezomib + sirolimus + tacrolimus Sirolimus, tacrolimus and methotrexate are drugs that suppress the immune system to try to prevent GVHD.
NCT00988442
This study tested a system of nursing telephone support to determine if it improves adherence to antiretroviral therapy (ART) in at-risk, treatment-experienced people.
NCT00401921
The primary aim of this protocol is to investigate a possible new, neuroprotective treatment to prevent cognitive deficits that occur after carotid endarterectomy. We will investigate whether a widely used antibiotic agent - minocycline - that has shown neuroprotective effects in animal models of neurological diseases - can reduce the cognitive deficits associated with the surgical procedure of carotid endarterectomy (CEA). Because these cognitive deficits are believed to be a result of small strokes (due to emboli and/or hypoperfusion), this study will provide preliminary data on the use of this drug as a neuroprotective agent in stroke - a leading cause of disability. (1) The first aim of this study is to examine whether 5 doses of minocycline administered 36 hrs before and 1 dose 12 hrs after the surgical procedure in patients undergoing CEA are effective to reduce the cognitive deficits associated with this procedure as compared with placebo. a. The null hypothesis is that there is no difference in cognitive performance changes after CEA between the patients that receive placebo or minocycline.
NCT01723423
The MROC Study seeks to evaluate and compare from the patient's point of view the leading options for breast reconstruction after mastectomy. This study will help patients, physicians, payers and policy makers better understand the various surgeries available for breast reconstruction. Although many women choose reconstruction, the number of options as well as their pros and cons can make decision making difficult and stressful. From this research, we hope to learn more about what works best for patients undergoing these operations.
NCT00383656
The purpose of this study is to explore the effects of synthetic gonadotropin-releasing hormone (GnRH) upon the pituitary and ovaries of women with infertility. Women diagnosed with GnRH deficiency, hypothalamic amenorrhea or acquired hypogonadic hypogonadism, will participate in this study. It is hoped that administration of GnRH will lead to proper stimulation of the pituitary gland and to normal ovulation and menstruation. \*\*WE ARE CURRENTLY RECRUITING ONLY WOMEN WITH A DIAGNOSIS OF IDIOPATHIC HYPOGONADIC HYPOGONADISM (IHH)\*\* Pulsatile GnRH has been approved by the FDA for use in women with primary amenorrhea due to complete GnRH deficiency. The overall goals of this protocol are to continue to use pulsatile GnRH in GnRH-deficient and other anovulatory women for ovulation induction and to examine specific physiologic hypotheses, which can only be addressed in this patient population.
NCT03224416
For decades, men who have sex with men (MSM) have carried the heaviest burden associated with the HIV epidemic in the United States. Although MSM represent a minority (i.e., approximately 4%) of the male population in the United States, in 2010 MSM accounted for 78% of new HIV infections among males. Furthermore, the estimated number of new HIV infections attributed to male-to-male sexual contact is currently rising. In order to improve interventions to decrease transmission of HIV among MSM, it is important to have a better understanding of predictors of risky sexual behavior. Alcohol use is among the most reliable predictors of risky sexual behavior. Unfortunately, studies of alcohol use and risky sex among MSM have mainly relied on survey-based methods that cannot advance our understanding of the causal mechanisms linking acute alcohol use to HIV risk behavior. This study will utilize an "alcohol/placebo/nonalcohol" design to examine the mechanisms underlying the association between the acute effects of alcohol (i.e., pharmacological and expectancy) and risky sexual decision making in MSM. Focal mechanisms include sex-specific delay discounting (SSDD), and the core constructs of the Cognitive Mediation Model. The alcohol/placebo/nonalcohol design involves three conditions. In the alcohol condition (target BrAC = 0.080g%), the participant will be told he is receiving alcohol and will receive beverages of 1:4 parts vodka and tonic water with dashes of lime juice and mint, all mixed in his presence. In the placebo condition (target BrAC = 0.000g%), the participant will be told he is receiving alcohol but will receive beverages of 1:4 parts flat tonic water (served from a vodka bottle) and tonic water, with a minimal amount of vodka "floated" on the surface (using a lime juice bottle) to provide the smell and taste of vodka, with lime juice and mint, all mixed in his presence and served in glasses with vodka-soaked rims. In the true control (or nonalcohol) condition, the participant will be told he is receiving no alcohol and will be given water (poured in his presence) in a volume comparable to the other conditions. This 3-group design will enable us to test the pharmacological effects of alcohol while accounting for potential expectancy effects. Participants (Target N = 150-180) will be randomly assigned to one condition; all will undergo the same protocol, which will be completed within one experimental session. The study protocol consists of baseline assessment, followed by beverage administration, followed by post-drinking assessment of SSDD and sexual decision making, followed by debriefing.
NCT02452645
Drs. Patricia Risica (Brown University) and Kim Gans (University of Connecticut) are Dual Principal Investigators for this project. The research team will first conduct formative research using focus groups and key-informant interviews of Family Child Care Home (FCCH) providers. This formative work will inform our adaptation of components of previous evidence-based interventions to create a new innovative intervention in both English and Spanish to improve food and PA environments of Family Child Care Homes (FCCH). The intervention will integrate: a) support from peer counselors with child care experience who will serve as team leaders for groups of FCCPs; b) tailored print and video materials; and c) a set of portable active toys. A cluster-randomized trial with 132 FCCH will evaluate the effectiveness of the intervention with a Steering Committee and Community Advisory Board guiding all aspects. The Specific Aims of the study are to: 1) Conduct formative research to inform the development and adaptation of the FCCH intervention. 2) Conduct a cluster-randomized trial of the intervention's efficacy with 66 FCCH providers and a control intervention with 66 demographically-matched FCCH providers to evaluate its impact on: a) Children's overall dietary quality at FCCHs; b) Children's PA and sedentary behaviors at FCCHs; and c) the physical and social food and PA environments of FCCHs. Evaluation methods will include survey data collection of the FCCH Providers; observation of children's' dietary intake and physical activity in FCCHs; recruitment of children within the FCCH for physical and survey measurement with permission from their parents.

NCT01697358
The purpose of this study is to compare the effectiveness of spinal cord stimulation (SCS) using the Medtronic Specify® 5-6-5 multicolumn surgical lead plus optimal medical management (OMM) versus OMM alone in patients suffering from predominant low back pain due to failed back surgery syndrome (FBSS).
NCT00792922
Trachoma, an ocular infection caused by C. trachomatis, is the second leading infectious cause of blindness worldwide. Years of repeated infection with C. trachomatis cause the eyelid to scar and contract and ultimately to rotate inward such that the eyelashes rub against the eyeball and abrade the cornea (trichiasis). The World Health Organization (WHO) has endorsed a multi-faceted strategy to combat trachoma, which includes the use of antibiotic treatment to reduce the community pool of infection with C. trachomatis. The objective of this study is to conduct a randomized, community-based trial in three countries (Niger, Tanzania and The Gambia), representing different baseline endemicities, of alternative coverages and frequencies of administration of mass antibiotic treatment as well as to determine the cost-effectiveness of these different strategies from a program perspective.
