Filter by:We hypothesized that brain death is associated with an early systemic inflammatory response, possibly combined with activation of apoptotic cell death, two events that may contribute to induce rapid organ dysfunction. In this study of brain-dead donors and controls, we assayed plasma cytokines and soluble factors, investigated plasma endotoxin levels as a triggering factor for inflammation, measured ex vivo cytokine production by blood leukocytes to determine whether immunosuppression occurred after brain death, and examined skeletal muscle biopsies to look for evidence of inflammation and increased apoptosis in peripheral tissue.
This is a prospective study to evaluating the ability of the PD2i Cardiac Analyzer to predict the risk of serious heart rhythm abnormalities in high-risk patients that do not already have an Implantable Cardioverter Defibrillator.
Title: Impact of daily zinc supplementation to infants born with low birth weight on mortality and severe disease requiring hospitalization Background: Zinc supplementation was shown to prevent diarrhea and pneumonia in 6 month to 3 year old children. Little is known about the impact of zinc supplementation of low birth weight (LBW) babies during first 6 months of life. Objective: The objectives were to determine the impact of daily zinc administration at 1RDA (5 mg) of elemental zinc to LBW infants on severe morbidity requiring hospitalization and on all cause mortality. Design: In a double blind randomized placebo controlled trial 2012 hospital-born infants with a birth weight <2500 g were randomly assigned to receive zinc or placebo for 6 months. Zinc group received 5 mg elemental zinc as acetate daily from 4 weeks age. Cause specific hospitalization deaths, episodes of diarrhea, acute respiratory infections, other illness, visits to health care providers and hospital OPDs were ascertained by in-depth interview and from documents like prescriptions, hospital tickets, medicine cartons at 3 and 6 months of age. Results: Number of infants with one or more diarrhea episodes was less by 17% (95% CI: 1% to 35%) in the zinc group but the numbers for ARI were similar in the two groups. The hospitalization rates due to all causes or diarrhea or ARI were similar in the two groups. Twelve in the zinc group and 9 in the placebo group died during 4 weeks to 6 months (p=0.36). We observed no significant difference for gain in weight and length at 3 months and 6 months between the groups. In a subgroup of infants the mean serum zinc concentration in the zinc group was 27% higher (p=0.004) than the placebo group. Conclusion: Hospital born, low birth weight infants do not seem to derive worthwhile benefit from daily zinc supplementation of recommended dietary allowance for zinc in terms of morbidity and growth during first six months of life.
This trial is a prospective, multi-center, randomized study of patients with coronary artery disease (CAD) and mild to moderate left ventricular (LV) dysfunction. The primary objective of this study is to test the hypothesis that Implantable Cardioverter Defibrillator (ICD) therapy in combination with medical therapy in patients with an infarct size greater than or equal to 10% of the left ventricular mass improves long term survival compared to medical therapy alone. In addition to the 2-arm randomized trial, the study will also include a non-investigational registry of non-randomized patients.
The purpose of this research study is to evaluate the effectiveness of metoprolol, a "beta blocker," in treating patients in the hospital with a cardiac arrest. It will be given intravenously (given into a vein). The subjects who will take part in this study are 18 years of age or older, are experiencing a cardiac arrest in the hospital, and are in a life threatening situation. Patients who develop a cardiac arrest require prompt electrical defibrillation (electrical shocks) to restore the normal beating rhythm of the heart. In patients who do not respond to electrical defibrillation, current standard of care recommends the use of medications which have been shown to be of unknown benefit. Some people recover from a cardiac arrest, but many people do not. We want to learn whether giving metoprolol will improve survival of patients with a cardiac arrest. A total of 100 patients will be enrolled in the study. Patients will receive either the standard of care with the drug epinephrine or the standard of care plus metoprolol.
This study evaluates the usefulness of noninvasive tests of the structure of the heart and the nervous system controlling the heart. It will assess whether combining tests that evaluate heart structure with others that measure the nervous system controlling the heart will identify most patients who develop serious heart rhythm problems after a heart attack.
This is a prospective cohort study of diet and cancer in relation to several major cancers, especially breast, prostate, and colorectal malignancies. The cohort comprises 50-69 year-old male and female members of the American Association of Retired Persons (AARP). In 1995-6 we mailed baseline questionnaires to 3.5 million AARP members. Over 615,000 AARP members responded, with over 540,000 providing adequate dietary data. Preliminary analysis indicates that the cohort, both men and women, has the desired wide distributions of percent calories from fat, dietary fiber, fruits and vegetables, and red meat. Approximately 330,000 of the initial respondents (with satisfactory data) returned a second questionnaire containing questions on exposures not assessed in the first instrument. In terms of field activities, the study has been relatively quiescent over the past year. At the end of the five-year period of observation, we will mail to cohort members a brief follow-up questionnaire primarily targeted to endpoint assessment. (Because of cancer registry lag-time, we do not expect to mail this questionnaire until early 2002.) Follow-up will be largely passive, through established state registries. The initial questionnaire mailing will be to AARP members in those states selected on the basis of having registries with adequate coverage and quality. We will use active follow-up, with record retrieval, for the small percentage of cohort members who have moved out of the cancer registry areas. The buccal cell collection pilot study has been completed; over 50% of those pilot study partricipants who had completed the baseline and risk factor questionnaires returned buccal cell speciments. Preliminary data from a pilot study of the end point ascertainment procedure indicate that cohort incidence rates for major cancers, determined from registry data, are consistent with SEER rates.
The Division of Cancer Preventionl (DCP, formerly DCPC), under extramural contracts to 10 U.S. clinical centers, is evaluating the effectiveness of screening for prostate, lung, colorectal and ovarian cancer (The PLCO Trial). In 1996 the NCI Executive Committee approved the expansion of the PLCO Trial to collect additional materials and to conduct additional studies. About, 74,000 men and 74,000 women, aged 55-74 years, have been randomized on a 50/50 basis into screening or usual care arms. Additional blood is collected from screened subjects and saliva for buccal cells from control subjects. Pathologic tissues are obtained for selected cases that develop cancer or selected related diseases (e.g. colon polyps, benign prostatic hyperplasia). Additional questionnaire-based risk and disease-related information is also collected, withconfirmation of disease status from medical records. Genetic, biochemical and questionnairebasedrisk information will be related to the development of cancer and other diseases in this population. Volunteers who provide samples for these studies will not routinely receive their individual results from the Additional Investigation. Subjects requesting such information, however, will be provided their test results. In 2009 the NCI Executive Committee approved the Extended Follow-up of subjects beyond the original 13-year follow-up period. Participants will be reconsented for the release of records to a single NCI-Designated Central Data Collection Center (CDCC), which will administer the annual mailings containing the annual study update questionnaire and a brief (1-2 page) risk factor questionnaire. Individuals who do not consent to release their identifiers to the CDCC will be followed up passively through linkage to state cancer registries and the National Death Index. This protocol Review Application is for (1) the collaboration of intramural scientists in the Division of Cancer Epidemiology and Genetics (DCEG) in the Additional Studies and (2) the coordination, in collaboration with DCP, of the Extended Follow-up.
The purpose of this study is to assess the long-term clinical outcomes after stenting bifurcation coronary artery lesions, and to determine whether simple or more complex techniques are associated with a better clinical outcome. We will also assess the risk factors associated with poorer clinical outcomes
Dying patients are often unable to clear secretions from their large airways, resulting in noisy breathing usually described as "death rattle." While there is no evidence that patients find this condition disturbing, the noises may be disturbing to the patient's visitors and caregivers who may fear that the patient is choking to death. In Israel none of the pharmaceutical drugs listed in the literature exist. Thus, Atropine drops which have been noted in the literature as being used, though according to our knowledge no evidence of clinical trials using sublingual Atropine were conducted. The study is designed as a randomly controlled, double blind crossover trial. The patient will serve as control for himself, as crossover between placebo and drug (randomly chosen) will take place. The administrator of the drug will be blinded to the medication, each time randomly beginning with a different drug (placebo or Atropine). We will evaluate Atropine Sulphate 1% ophthalmic drops effect on 33 patients using a noise score scale of 0-3. Noise scores will be taken at the start; 30 min after drug/placebo administration and every hour thereafter. After 4-hours crossover will take place and evaluation will follow the same protocol.
