NCT00106938

NCT00501215
Primary hyperparathyroidism (PHPT) is an endocrine disorder that disrupts calcium metabolism and has a broad range of clinical manifestations. With respect to the nonclassic, subjective symptoms that have been reported to be associated with PHPT, such as sleep disturbance, neurocognitive dysfunction, mood disturbance, fatigue, and decreased quality of life, there is a lack of objective data on the extent to which these symptoms are affected by parathyroidectomy. There have been reports of improvements in sleep in patients following parathyroidectomy, but these have been based solely on subjective sleep surveys. To date, there are no published studies on objective sleep evaluations of patients with PHPT. The overall goals of this protocol are to ascertain the feasibility of performing sleep studies on patients with PHPT, and to obtain pilot data on the effects of parathyroidectomy on those sleep studies. It is hypothesized that it will be feasible to evaluate sleep parameters in patients with PHPT in the M. D. Anderson Sleep Center. Towards testing this hypothesis, the specific aims are: Specific Aim 1: To assess the feasibility of using nocturnal polysomnography (PSG) to evaluate the primary outcome measure of total sleep time. Specific Aim 2: To assess the feasibility of using nocturnal polysomnography (PSG) to evaluate the secondary outcome measures of sleep architecture, arousal index, sleep efficiency, wake after sleep onset, and sleep onset latency in patients with PHPT. Specific Aim 3: To assess the feasibility of evaluating the secondary outcome measures of subjective sleepiness as tested with the Epworth Sleepiness Scale (ESS), and of sleep quality as tested with the Brief Sleep Disturbance Scale (BSDS) in patients with PHPT. Specific Aim 4: To assess the feasibility using a randomized "wait-list"-control design to assess the effects of parathyroidectomy on sleep measures obtained with nocturnal PSG.
NCT01884324
Primary objective: to test the hypothesis that elective early delivery will protect the fetal bowel from the deleterious intrauterine factors late in the pregnancy and will be associated with improved neonatal outcomes. Secondary objective: to introduce a standardized diagnostic, monitoring, and postnatal surgical management of infants with gastroschisis.
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.
NCT01725347
The Validation of a Digital Diet Method project is very innovative because it links three methods to address the gap in measuring food intake of HS preschool children. Data collection is based on EMA theory; participant burden is low, and the Food Image App decreases participant and staff burden even further. Data management and analysis are semi-automated and relies on advanced computer algorithms. A strength of this approach is its semi-automation, which allows us to leverage the strengths of human operators and computer automation.
NCT02216968
The purpose of this study is to test the feasibility of an innovative approach to increase the amount of vegetable's (V) intake consumed by preschool children who are predominately African-American (AA) and Hispanic-American (HA).
NCT02512393
The purpose of this research is to study the effects of Transcranial Direct Current Stimulation (tDCS) on clinical pain, mobility disability, and pain sensitivity to gain a better understanding of the factors that cause pain and disability in people with knee osteoarthritis (OA). In particular, people from different ethnic and racial groups may experience OA pain differently which is why the focus will be on older Asian Americans and non-Hispanic whites. It is important to find a reason for such difference so that a better treatment can be found for all OA patients. In addition, the research study will examine if there is any ethnic differences in pain and mobility disability. The investigator hypothesize that Asian Americans will report greater pain and mobility disability than non-Hispanic whites, and that active tDCS will result in improvement in pain and disability compared to sham tDCS.
NCT01677780
This open-label, extension study is designed to provide continuing treatment with RO5045337 to participants who have completed parent studies NO21279 (NCT00623870), NO21280 (NCT00559533), NP25299 (NCT01164033), NP28021 (NCT01605526) or NP28023 (NCT01635296). Participants are eligible to participate in this study if they have completed required Phase 1 study assessments for primary objectives of respective parent protocol and are having evidence of clinical benefit (as defined by the parent protocol). Participants will continue the most similar dose and formulation available (which does not exceed the maximum tolerated dose \[MTD\] or the maximum safely administered dose for that formulation during Phase 1) and the same schedule of RO5045337 treatment that they were receiving at the time of transitioning from the parent clinical study protocol.
NCT02213354
This is a Phase II randomized, partially-blinded, controlled trial in 360 (up to 600) males and females, 65 years of age and older, who are in good health and meet all eligibility criteria.

NCT00883909
ARI103094 is a follow-up study in adult male subjects who have received investigational product (either dutasteride or placebo) in the REDUCE Study (REduction by DUasteride of prostate Cancer Events), ARI40006, A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study of the Efficacy and Safety of Dutasteride 0.5mg Administered Orally Once Daily for Four Years to Reduce the Risk of Biopsy-Detectable Prostate Cancer. There are 2 parts to this REDUCE Follow-Up Study, Part A and Part B: * REDUCE Follow-Up Study, Part A, is a 2 year observational study which will follow eligible subjects for 2 years after completion of the 4 Contact in the REDUCE study. Eligible subjects for Part A, the 2 Year Observational Study fall into 3 groups as follows: (1) REDUCE subjects who completed treatment with investigational product (dutasteride or placebo) through the REDUCE 4 Year study visit \[Visit 10\], (2) REDUCE subjects who developed prostate cancer, were withdrawn from investigational product and participated in Prostate Cancer follow-up until the REDUCE 4 Year study visit \[Visit 10P\] or (3) REDUCE subjects who were withdrawn from investigational product and participated in observational phone follow up until the REDUCE 4 Year phone call after withdrawing from IP (expected Visit 10). The objective of this observational study for eligible REDUCE subjects is to collect and summarize data on prostate cancer (the incidence of newly diagnosed prostate cancers and changes in prostate cancer diagnosed during the REDUCE study) and serious adverse events (SAEs) for 2 years beyond the prospectively planned 4 year double blind, placebo-controlled study, REDUCE. * REDUCE Follow-Up Study, Part B, is for collection of cancer positive prostate biopsy tissue blocks/slides from subjects who were diagnosed with prostate cancer in the REDUCE study.
