The purpose of this study is to determine if HIV-specific canarypox vaccine and/or interleukin-2 (IL-2) will control viral load (amount of HIV in the blood) after HIV treatment is withdrawn for a certain time period.
The purpose of the study is to examine ways in which a clinical information system can help patients better recognize the signs and symptoms of an acute myocardial infarction (heart attack) and to take actions to decrease morbidity and mortality that may be related to delay in seeking treatment. The software-based intervention will use the best scientific evidence to create tailored strategies using a patient's specific health data. This approach is based on well-established cognitive and behavioral educational models.
The primary purpose of this randomized clinical trial is to test the efficacy of motivational enhancement (ME) therapy combined with biologic feedback (fetal ultrasound) for increasing smoking quit rates among low-income pregnant women considered resistant smokers. We hypothesize that ME along with biofeedback will increase the rate of validated smoking cessation at 8 months gestation by at least 10 percentage points above that produced by "Best Practice" (BP) counseling alone. This study will also examine reduction of smoking among non-quitters and maintenance of smoking cessation through 6 weeks postpartum among women who quit. Prenatal smoking is the leading preventable cause of low birth weight in the US. Reduction in smoking during pregnancy could result in significant improvements in pregnancy outcomes and reducing the cost of health care. There is evidence that low-intensity pregnancy smoking cessation programs may be inadequate for women who are more addicted, and at educational and economic disadvantage. Motivational enhancement strategies have shown considerable promise in the treatment of addictive behaviors. Physiological feedback highlighting prenatal effects of smoking and benefits of cessation has been found to enhance prenatal smoking cessation counseling. An intervention that combines motivational enhancement counseling and physiological feedback may have powerful effects beyond low-intensity interventions or usual counseling.
The purpose of this study is to determine if 2 doses of Pneumococcal Conjugate Vaccine (PCV) followed by 1 dose of Pneumococcal Polysaccharide Vaccine (PPV) in HIV-infected children on anti-HIV therapy is helpful and safe in fighting pneumococcal infections in this group of children. This study will also look at the protection provided by childhood vaccination against measles, pertussis, and hepatitis B virus. Pneumococcal infections are the most common AIDS-related infection in HIV-infected children. PCV may help reduce the chances of HIV-infected children getting pneumococcal infections. This study will look at whether pneumococcal vaccines are safe and effective in HIV-infected children receiving HAART. It will look at whether HIV-infected children are protected by childhood vaccines received previously and if more doses are safe and improve protection.
The purpose of this research study is to investigate the mechanism of action of a new investigational medication (drug), NNC 90-1170, which is being developed for the treatment of type 2 diabetes (adult onset type of diabetes. NNC 90-1170 is a modified form of a hormone, Glucagon-Like Peptide 1 (or GLP-1), which is important for controlling insulin levels. Insulin, another hormone, is also important for controlling blood glucose levels, which are higher than normal in people who have type 2 diabetes. This study will measure the effect of NNC 90-1170, active investigational drug, to cause insulin to be released from the pancreas in response to increasing blood glucose concentrations. These results will be compared to that of a group of healthy volunteers of similar age and body weight who do not have diabetes. Also, various other hormones and substances that are known to control blood sugar will be measured in blood samples that will be drawn. One dose of NNC 90-1170 will be given to subjects with type 2 diabetes only in this study, and the effects of this dose will be compared to a placebo (inactive substance that looks like the active drug). This is a crossover study, which means that subjects will be treated both with NNC 90-1170 and with placebo. The order in which subjects will receive the treatments will be determined by chance (randomly). The study will be conducted as a so-called "double-blind" study, meaning that neither subjects nor study doctors will know the order in which subjects will be given each treatment until the study is over. The study will include approximately 15 healthy volunteers and 15 volunteers with type 2 diabetes, and it will be conducted at 1 clinic (the University of Michigan Health System) in the United States.
The purpose of this study is to evaluate the effectiveness of a nutritional supplement that has been developed to improve the brain function of a patient with Alzheimer's disease.
The Williams syndrome is a disease in which supravalvular aortic stenosis, an elfin facies, mental retardation and other congenital defects are sometimes associated with abnormal vitamin D and calcium metabolism. Whereas some patients have been reported to show increased sensitivity to vitamin D or an exaggerated response of serum 25-hydroxyvitamin D {25(OH)D} to administration of vitamin D and to have hypercalcemia caused by increased circulating 1,25-dihydroxyvitamin D{1,25(OH)2D} in infancy and early childhood, most patients have normal calcium metabolism and normal values for circulating 25(OH)D and 1,25(OH)2D. We propose to carry out further studies of vitamin D metabolism to elucidate the mechanism(s) for abnormal vitamin D metabolism. We will determine the response of serum 1,25(OH)2D to administration of 1,25(OH)2D3. Measurement of the 1,25(OH)2D in the patients compared to normal subjects will be the primary outcome.
The purpose of this study is to see if the full daily dose of Combivir (zidovudine [ZDV]/lamivudine [3TC]) taken once a day is as effective as the usual recommended twice-a-day dose. Studies have shown that the antiviral activity of ZDV can continue in the body even after there does not appear to be any ZDV left in the blood. This occurs because the body breaks down the drug into substances that remain active against HIV. The body also breaks down 3TC, a drug that is combined with ZDV in the Combivir product, in a similar way. Since antiviral activity may continue after Combivir is removed from the body, it may not be necessary to take the drug as often as once thought. This study carefully measures levels of the active substances in order to find out whether the same amount of antiviral activity occurs with less-frequent dosing.
The purpose of this study is to compare immune system activity in young people and older people who do not have HIV. This information will be compared to that of HIV patients in another study. Aging affects immune system activity. This study will look at some of the factors involved. HIV also affects immune system activity. The results from this study, using healthy volunteers, will be compared to those in another study of HIV-infected patients. This may provide information on immune system activity in aging and HIV.
OBJECTIVES: I. Compare the safety and efficacy of clostridial collagenase vs placebo in terms of improving the degree of flexion deformity, range of finger motion, and grip strength in patients with residual stage Dupuytren's disease. II. Compare the overall clinical success rate, time to return to normal finger contracture to within 0-5 degrees of normal (zero degrees), and frequency of cord rupture in the joint of patients treated with these regimens. III. Compare the baseline change in degree of finger flexion deformity, range of motion of the treated finger, and strength of hand grip (in pounds) in patients treated with these regimens. IV. Compare the frequency distribution of the number of patients with reduction in finger contracture to within 0-5 degrees of normal (zero degrees) and the number who require re-treatment with open-label collagenase after treatment with these regimens.
