NCT ID: NCT00814814 Active, not recruiting - Clinical trials for Cardiopulmonary Arrest Outcome

Protein S100 Beta as a Predictor of Resuscitation Outcome

Start date: February 2008
Phase:
Study type: Observational

Management of cardiac arrest is complicated by the lack of a readily available tool identifying individuals who are likely to be successfully resuscitated. S100 beta is a protein that originates in the astroglial cells of the brain, and NSE (Neuron Specific Enolase) is another protein that originates in the neurons themselves. In the laboratory, the concentration of these proteins correlate with evidence of brain damage after head trauma, stroke and exposure to low levels of oxygen. The concentration of these proteins in the blood of human survivors of cardiopulmonary resuscitation in humans is much higher than in patients who were resuscitated but did not survive. However, it is still unclear whether survivors from cardiopulmonary resuscitation have higher levels of these proteins in their blood if they survive with neurological injury secondary to the arrest and resuscitation. Hypothesis: In humans, the blood concentrations of protein S100 beta and NSE during and after resuscitation can predict who will die despite cardiopulmonary resuscitation and who will survive with neurological injury secondary to the arrest and resuscitation.

NCT ID: NCT00813644 Active, not recruiting - Endoscopic Skills Clinical Trials

A Study of Flexible Ureteroscopy Proficiency After Training on the Uromentor Simulator

UROSIMULATOR08
Start date: December 2008
Phase: N/A
Study type: Observational

The development of virtual reality (VR) simulators is changing surgical endoscopic education. The translation of VR skills into clinical endoscopic proficiency has been shown by M.PEARLE. The improvement in performing endoscopic tasks after VR training was evaluated on a cadaver. Our goal is to evaluate the performance of novice endoscopists at the operating room by a randomized controlled study comparing subjects randomized to train on a the "UroMentor" simulator to those without VR training.

NCT ID: NCT00809939 Active, not recruiting - Pregnancy Clinical Trials

17 Alfa Hydroxyprogesterone Caproate Versus Natural Progesterone for the Prevention of Preterm Labor

Start date: December 2010
Phase: Phase 3
Study type: Interventional

Preterm deliveries play a significant role in neonatal morbidity and mortality. Previous studies showed that administration of progesterone to pregnant women at high risk, decrease spontaneous preterm deliveries. The purpose of this study is to compare between two different modes of treatment with progesterone for the prevention of preterm delivery: weekly injection of 17 alfa hydroxyprogesterone caproate versus daily vaginal administration of progesterone in terms of efficacy, comfort and compliance, safety and cost of treatments.

Start date: November 2008
Phase: Phase 1/Phase 2
Study type: Interventional

The objective of the MERITAGE Trial is to evaluate the safety and efficacy of focal delivery of radiation for the treatment of subfoveal choroidal neovascularization (CNV) associated with wet age-related macular degeneration (AMD) in patients that require persistent injections of Anti-VEGF therapy to maintain an adequate response to treatment.

NCT ID: NCT00801372 Active, not recruiting - Clinical trials for Pregnant, Healthy Females

Use of Existing Fibroblast Cells to Convert to Induced Pluripotent Stem Cells

Start date: November 2008
Phase:
Study type: Observational

Induced pluripotent stem cells potentially may be useful in the future as an unlimited source of cells for transplantation. The major goal of the project is to develop human iPS cells from existing lines of fibroblasts that were originally donated as clinical grade feeders for the development of clinical grade hESCs. The clinical grade feeders were developed from aborted fetuses, foreskin and umbilical cord.

NCT ID: NCT00801333 Active, not recruiting - Clinical trials for Amyotrophic Lateral Sclerosis

Derivation of Induced Pluripotent Stem Cells From an Existing Collection of Human Somatic Cells

Start date: November 2008
Phase:
Study type: Observational

Induced pluripotent stem cells potentially may be useful in the future as an unlimited source of cells for transplantation. The major goal of the project is to develop human iPS cells from various types of cell cultures or lines from existing collections. The IPS cells will be developed for modeling diseases, for developing the technology that may eventually allow the use of IPS cells for transplantation therapy, and for basic research.

NCT ID: NCT00797329 Active, not recruiting - Alcohol Abuse Clinical Trials

Biological and Cognitive Markers of Violent Behavior in Forensic Patients With Polysubstance Use: Retrospective Evaluation

Start date: July 2008
Phase: N/A
Study type: Observational

Aggressive behavior, both in the form of violence toward others (injury-inflicting or homicide) or toward oneself (suicide or self-injures) create problems of patient management, treatment and paroles. Biological causes of violent crime were hypothesized by Eysenck (1978), who believed that criminality resulted from a nervous system distinct from that of most people. The prefrontal cortex, regulates planning of motor acts and executive functions, which are critical for inhibitory ability and control of impulsive outburst were found to be impaired in violent subjects (Hoaken et al, 2003; Blair, 2001; Brower and Price, 2001; Filley et al, 2001; Raine et al, 2000; George et al, 2004; Dolan and Park, 2002; Stevens et al, 2003; Raine and Yang, 2006), especially in impulsive offenders murderers (Raine et al, 1997; 1998). Violence act influenced by nonplaning outboards definite as impulsive aggression (Linnoila and Charney, 1999), which one of the most important factor influenced by dangerous behavior in general (for review: Skodol, 1998, Moeller et al, 2001; Pontius, 2000; 2004; Siever, 2008). Cholesterol and fats have many roles and may influence brain function and behavior through modification of membranes; myelin; enzyme function; absorption and transport of fat-soluble vitamins and toxins; and steroid hormones and through effects on production, reuptake, or metabolism of neurotransmitters (Boston et al, 1996). Since 80-th a strong association was found between low cholesterol levels and violent behavior, an association that was not due to age, race, sex, or diagnosis (Mufti et al, 1998; New et al, 1999; Alvarez et al, 2000; Golomb et al, 2000; Hillbrand et al, 2000; Troisi and D'Argenio, 2006; Chakrabarat and Sinha, 2006). Associations between violent behavior, cognitive functioning and total cholesterol level were contradicted with difference in samples and behavioral parameters: homicide, homicide attempts, rape, physical or verbal aggression, complete suicide or suicide attempts, only partially accounted for each measure of behaviors, suggesting that further investigation is warranted. Because of the inconsistencies in the available data, we studied retrospectively a group of criminal offenders with alcohol and drug use. Our analysis of lipid constituents in serum focused on TC, HDL, LDL, and TG. Significance of the study. It is possible that cholesterol profile is a biomarker and potential predictor of violent in patients with polydrug use. The purpose of this retrospective study is to investigate the correlations between cholesterol and cognitive profiles in psychiatric patients with violent behaviour. The demographic and criminal records, clinical characteristics, cholesterol profiles, and cognitive performance data of these patients will be will be intercorrelated.

NCT ID: NCT00795613 Active, not recruiting - HODGKIN LYMPHOMA Clinical Trials

Positron Emission Tomography (PET)-Adapted Chemotherapy In Advanced Hodgkin Lymphoma (HL)

HD0607
Start date: June 2008
Phase: Phase 2
Study type: Interventional

The purpose of this multicenter clinical trial is to assess the clinical impact of dose intensification performed very early during treatment in a subset of poor prognosis, advanced-stage Hodgkin Lymphoma patients, defined as PET-positive after two courses of conventional adriamycin (doxorubicin), bleomycin, vinblastine and dacarbazine (ABVD) chemotherapy.

NCT ID: NCT00782782 Active, not recruiting - Clinical trials for Congestive Heart Failure

Vascular Sensitivity to Adrenergic Agonists in Patients With CHF and in Healthy Subjects

Start date: August 2008
Phase: N/A
Study type: Observational

Congestive Heart failure (CHF) is asociated with changes in cardiac function and vascular responses. The aim of this study is to characterize these differences. Our hypothesis is, that there are differences in vascular responses between healthy subjects and patients with CHF.

NCT ID: NCT00748722 Active, not recruiting - Clinical trials for Breast Reconstruction

Pre-Operative Imaging of Abdominal Wall Perforators Using CT Angiography

DIEP
Start date: September 2008
Phase: N/A
Study type: Observational

Abdominal donor-site flaps, including the transverse rectus abdominis musculocutaneous (TRAM) and deep inferior epigastric artery perforator flaps(DIEP), are standard in autologous breast reconstruction. With significant variation in the vascular anatomy of the abdominal wall, preoperative imaging is essential for preoperative planning and reducing intraoperative error. The quest continues for optimal preoperative assessment. Computed tomographic angiography has recently been proposed as a noninvasive modality for this purpose. It provides the location of the perforator vessels, diameter and anatomic course in regards to the rectus muscle. In this study we will perform preoperative lower abdominal computed tomographic angiography in DIEP flap breast reconstruction patients.
