NCT01397747
The primary objective is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. Lesions will be confirmed as malignant by histopathologic examination. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.

NCT00133016
The purpose of this clinical trial is to investigate the efficacy of early amniotomy on reducing both the duration of labor and the frequency of dystocia in nulliparous women undergoing an induction of labor. This research project is a prospective, parallel clinical trial, in which subjects are randomized into one of two treatment groups: those who undergo early amniotomy and those who do not undergo early artificial rupture of the amniotic membranes.
NCT02130791
Insufficient sleep is common, affecting 20-40% of adults, and resulting from sleep disorders, medical conditions, work demands, stress/emotional distress, and social/domestic responsibilities. It produces significant social, financial and health-related costs, and it has increasingly become a major public health concern as population studies worldwide have found that reduced sleep duration is associated with increased risks of obesity, morbidity, and mortality. It is well established that sleep loss causes fatigue and sleepiness, as well as errors and accidents that are due to its adverse neurobehavioral effects on alertness, mood, and cognitive functions. However, there are substantial, trait-like differences among people in the extent to which they experience such neurobehavioral deficits when sleep deprived. Common genetic variations involved in sleep-wake, circadian, and cognitive regulation may underlie these large inter-individual differences in neurobehavioral vulnerability to sleep deprivation, though it remains unclear whether different types of sleep deprivation involve the same phenotypic responses and same genotypic contributors. This project will be the first large-scale investigation of markers of differential cognitive vulnerability to both acute total sleep loss and chronic partial sleep loss. It will identify individuals who are at significant risk for fatigue and severe impairments from sleep loss. A total of 110 healthy adults will undergo a 13-day laboratory protocol to thoroughly characterize their cognitive, psychological and physiological responses to two of the most common forms of sleep loss--acute total sleep deprivation (1 night of sleep loss) and chronic partial sleep deprivation (5 nights of sleep limited to 4 hr). The findings from this study will represent a critical first step toward tailoring appropriate follow-up interventions for sleep loss and its symptomatic relief by finding predictors of at-risk individuals who should avoid sleep loss whenever possible, and/or seek effective countermeasures. Whether or not markers of neurobehavioral vulnerability to sleep loss are identified, the results of the project will help inform public policies pertaining to the need for adequate sleep and for countermeasures for sleep loss, and also will further our understanding and management of vulnerability to excessive sleepiness due to common sleep and medical disorders.
NCT02615899
Background Balance impairment is a key factor contributing to falls in older adults. Conceptually, clinicians may be able to prescribe targeted exercises if specific impairments can be identified. Objective Our objective was to use a model of balance subsystems to identify balance impairments and demonstrate the effectiveness of targeted (matched) exercises to improve balance and reduce fall risk in community-dwelling older adults. The investigators used the Balance Evaluation System Test (BESTest) as the model because it categorizes balance into 6 subsystems. Design Randomized, partially blinded, pretest-post-test clinical trial consisting of 2 Phases: 1. A comparison between impairment-matched exercises and a control, and 2. A comparison between impairment-matched and mismatched exercises. Setting Senior independent living community. Participants Adult volunteers (n = 40; aged 74-94) recruited as sample of convenience who met the criteria. Participants (n = 20) identified with impairment in the biomechanical (BC) constraints subsystem and participants (n = 20) with impairment in anticipatory postural adjustment (APA) subsystem were enrolled and randomized into 2 subgroups (matched and control/delayed mismatched; n = 10 each subgroup). Intervention Phase 1: Participants in the matched subgroup received a 6-week exercise program matched to their impaired subsystem while the mismatched subgroup served as control. Phase 2: Following the delay, participants in the mismatched group received a 6-week exercise program mismatched to their impairment. Measurements Primary outcome variables were scores on the targeted subsystem (BC, APA), BESTest total, Berg Balance Scale, and fear of falling measure. Quality of life was a secondary outcome. Outcome data were collected by the tester blind to pretest scores and group allocation. Results The matched exercise subgroups demonstrated both statistical and clinical improvement in all outcome variables compared to the control; and showed greater improvement in balance impairments compared to the mismatched subgroup, but not in fall risk reduction. Limitations The therapist who administered the pretest knew the subgroup assignment and implemented the exercises. Conclusions Results provide preliminary evidence that using a balance assessment model to identify impairments in the BC and APA subsystems and prescribing targeted exercises reduces these balance impairments for older adults and may warrant future studies.
NCT00992173
This is a multi-center, single arm trial of two doses of 18 mCi/kg of Ultratrace iobenguane I 131 administered to subjects with high-risk neuroblastoma. Iobenguane I 131 is a drug that has already been used in many children to treat neuroblastoma, and it is known to shrink some of the tumors, and cause manageable side effects. When administered intravenously, Iobenguane I 131 accumulates in the neuroblastoma cancer cells and causes them to die. In this study the investigators are investigating the use of a new form of Iobenguane I 131 called Ultratrace iobenguane I 131. This form is expected to deliver higher amounts of radioactive I 131 to the neuroblastoma cells. The primary purpose of the study is to determine if Ultratrace iobenguane I 131 can be used to successfully treat high-risk neuroblastoma. The study will also assess the safety of Ultratrace iobenguane I 131 when given to patients with high-risk neuroblastoma.
NCT01192022

NCT01964352

NCT01446471
The aim of this study is to investigate the predictive value of the presence or absence of cardiac activity by bedside ultrasound during cardiac arrest. The investigators anticipate based on previous research that patients who suffer a cardiac arrest and have cardiac activity on bedside ultrasound will have a greater chance of surviving to hospital admission. The investigators hypothesis is that the mortality rate in patients in cardiac arrest with no cardiac activity by ultrasound will have a mortality rate of 100%.
NCT01709162
The purpose of the study is to determine whether additional doses of ipilimumab have a positive effect on survival in the treatment of advanced melanoma that has progressed after successful initial treatment with ipilimumab.
NCT02130518
Long-term indwelling urinary catheters are associated with chronic recurrent urinary tract infections and blockage caused by crystalline biofilm accumulation (encrustation) of the catheter surfaces. When the urine and catheter are colonized by urease-producing bacteria such as Proteus mirabilis, encrustation of the catheter is likely to occur. The use of a catheter irrigation solution that can prevent biofilm formation and encrustation leading to blockage may keep the catheter patent longer, resulting in fewer catheter changes, potentially lower incidence of UTIs and better patient quality of life. Auriclosene is a non-antibiotic, fast-acting, broad-spectrum antimicrobial, which exhibits potential for the rapid decolonization of a range of urologic pathogens, including the urease-producing Proteus mirabilis. Subjects will be randomized to either Auriclosene Irrigation Solution or Auriclosene Vehicle solution.
