A Placebo Controlled Study Evaluating The Effectivess Of Medication In Preventing Seasonal Affective Disorder
NCT01332032
This randomized study compares the effectiveness and cost-effectiveness of 3 proven methods of reaching out to women who are coming due for or who are overdue for a mammogram. The study originally embedded in a community healthcare plan and an associated community clinic, now accepts patients using the community clinic and 3 other health care plans. The study makes use of a complex computer driven reminder system. The study also will examine ways to improve the efficiency and sequencing of the interventions by identifying patient factors associated with intervention effectiveness.

Adults and children one year of age and older with diagnosis of adenoviral conjunctivitis in at least one eye based upon a positive adenovirus test result using the Aden-Detactor Plus kit (Rapid Pathogen Screening, Inc). Subjects will be randomly assigned to receive either NVC-422 or Vehicle.
NCT00746759
The purpose of the research study is to develop a new, more sensitive, and less invasive test for diagnosing lung cancer at an earlier stage, when it can more easily be cured. The investigators hypothesize that certain genes are expressed differently in current and former smokers who have lung cancer, and this difference in gene expression may be a biomarker for lung cancer.
NCT01222572
In this research study the investigators are looking for the highest dose of a stereotactic radiation boost that can be given safely. Because stereotactic radiation is so precise, the investigators are testing whether it can be used to increase the dose to the primary tumor without significantly increasing the side effects the participant experiences; the goal is to improve the likelihood of killing the tumor.
NCT00877292
The study will examine the sensitivity and specificity of a circulating cell-free nucleic acid test (DNA/RNA) to identify Down syndrome between about 10 weeks and 21 weeks 6 days gestation. In addition, the new test may be used to identify trisomy 13 and 18 as part of a more complete laboratory developed test. We hypothesize that the new circulating cell-free fetal NA-based test will accurately and precisely measure specific fetal markers in maternal circulation and that measurement will lead to the ability to noninvasively identify with high sensitivity and specificity, fetal chromosome abnormalities, such as Down syndrome.
NCT00003325

NCT01888848
This study is being conducted to assess the effect of dietary blueberry supplementation on cognition and mobility in older adults. It is hypothesized that plant compounds, present in blueberries, may improve cognition and mobility by protecting against oxidative stress and inflammation.
NCT01346293
The study was designed to compare the safety and immunogenicity of DTap-IPV with DAPTACEL® + IPOL® as the 5th dose booster in children ≥ 4 to \< 7 years of age in the US and Puerto Rico who were previously vaccinated with DAPTACEL® and/or Pentacel® vaccines only. Primary Objectives: * To compare the pertussis \[Pertussis Toxoid (PT), Filamentous Haemagglutinin (FHA), Pertactin (PRN), and Fimbriae Types 2 and 3 (FIM)\] booster responses and geometric mean concentrations (GMCs) (as measured by enzyme-linked immunosorbent assay \[ELISA\]) following DTap-IPV vaccination to those elicited following DAPTACEL® + IPOL® vaccination when administered as a 5th dose. * To compare the diphtheria and tetanus booster responses and GMCs (as measured by ELISA) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations when administered as a 5th dose . * To compare the Inactivated Poliovirus Vaccine booster responses (as measured by neutralizing assay) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations. Observational Objectives: * To compare the polio (types 1, 2, and 3) geometric mean titers (GMTs) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations. * To assess the safety of DTap-IPV vaccine or DAPTACEL® + IPOL® vaccine when administered as the fifth dose booster vaccine in participants previously vaccinated with DAPTACEL and/or Pentacel vaccines.
NCT00837486
Medtronic, Inc. sponsored an investigational study of the Reclaim™ Deep Brain Stimulation (DBS) System in people that have treatment-resistant depression. Depression is a mood disorder and a serious medical condition that affects millions of Americans. Depressive symptoms may include loss of interest in things typically enjoyed; decreased energy levels; difficulty concentrating or making decisions; restlessness; and feelings of pessimism, hopelessness, and worthlessness. Treatment-resistant depression is a chronic and severe form of depression characterized by failure to respond to traditional forms of treatment, such as antidepressant medications and electroconvulsive therapy. Treatment-resistant depression significantly impacts quality of life, productivity, and is a major contributor of disability world-wide. This randomized, double-blind, sham stimulation-controlled, multi-center, prospective, parallel design study used deep brain stimulation technology to test whether active bilateral stimulation can safely and effectively improve depressive symptoms in patients with treatment-resistant depression compared to sham stimulation. Participants meeting criteria for the study were implanted with the Reclaim DBS System. Participants in the active group, who received active stimulation, were compared to the control group, who received sham stimulation, during the 16-week blinded-treatment phase. All participants were monitored for changes in depressive symptoms. After the blinded-treatment phase, all participants received active stimulation. Candidates for the trial were adults who had major depressive disorder and had not responded to several treatments for depression. Participants in the study continued to receive their current antidepressant medications while participating in the trial.
NCT00781755
This is a clinical research protocol to study the efficacy of combined varenicline (Chantix) and motivational interviewing (MI) for smoking cessation in a sample of smokers who have been diagnosed with schizophrenia or schizoaffective disorder. The study is a double-blind, randomized, controlled, subacute treatment trial of MI plus varenicline (VAR-MI) versus MI plus placebo (PLA-MI). The pharmaceutical treatment will utilize Chantix at a dose of 1 mg/day for a period of two weeks. The primary goal is to determine if VAR-MI decreases baseline behavioral measures of urge and withdrawal and reduces baseline rates of cigarette consumption. The primary efficacy measures of VAR-MI vs. PLA-MI treatment are: Minnesota Nicotine Withdrawal Scale, Questionnaire for Smoking Urge-brief, number of cigarettes smoked per day in the previous week, CO levels, and Brief Psychiatric Rating Scale and Positive And Negative Symptom Scale scores on the last day of the study. Other primary outcome measures are to determine the effects of VAR-MI and PLA-MI on smoking cue-induced urges in tobacco cue reactivity sessions and reward responsiveness as assessed by a computerized task.
NCT01203475
This study was a multicenter, prospective cohort study to define postnatal longitudinal growth for very low birth weight (VLBW) infants. The objectives were: 1) to develop postnatal growth curves for VLBW preterm infants that would permit an assessment of growth velocity; 2) to relate growth velocity and nutritional practices (duration of parenteral nutrition, age at first enteral feeding, and age at full enteral feeding); 3) to compare growth velocity in infants who are small-for-gestational age (SGA) with infants who are appropriate-for-gestational age (AGA); and 4) to relate growth velocity to several common, major morbidities, including chronic lung disease (CLD), nosocomial infection (or late-onset infection) and necrotizing enterocolitis (NEC). These growth data may be useful in identifying preterm infants who are growing slowly despite current nutritional support and in designing and performing clinical trials of nutritional interventions.
NCT01753674
Our hypothesis is that TA-65, a dietary supplement will help to reduce insulin resistance and plasma glucose in individuals classified with metabolic syndrome.
