11 Clinical Trials for Various Conditions
This study will: 1) test the effectiveness of a program to prevent the exposure of infants to environmental tobacco smoke; and 2) evaluate the health effects associated with prenatal and postpartum exposure to tobacco smoke products and environmental tobacco smoke among infants. African-American and Hispanic women who are 18 years of age or older, and who are between 28 and 35 weeks pregnant may be eligible for this study. Participants complete an interview and home visit assessment and are then randomly assigned to participate in Program A or Program B of the study, as follows: Program A: Involves discussions with an Infant Health Advisor about parenting skills to promote child safety and infant growth and development, such as ways to prevent childhood injuries caused by falls, poisons, and other hazards. Program B: Involves discussions with an Infant Health Advisor about ways to prevent infant tobacco smoke exposure, such as how to adopt smoke-free household rules in the home and how to work with friends and family members to prevent the baby from being exposed to tobacco smoke. In addition, participants who smoked cigarettes before becoming pregnant or while pregnant are given advice on how to quit smoking and how to remain a non-smoker once the baby is born. Participants come to the clinic four times- once during a regularly scheduled prenatal visit and again when the baby is 6 weeks, 4 months, and 6 months old - to see the Infant Health Advisor for the activities described above in Program A or Program B. Between visits, the Advisor calls the participant to check on her progress regarding the program objectives. In addition, the study involves the following for all participants: * Telephone interview during the week after joining the study to obtain information on participant's background, pregnancy and family history, tobacco use and exposure to other people's cigarette smoke during pregnancy, strategies to reduce tobacco use and exposure, stressful life events, drug and alcohol use during pregnancy, and sources of social support. Similar interviews are repeated when the baby is 6 weeks old, and again when the baby is 4 months, 6 months, and 12 months old. * Home visit about 1 week after entering the study to check the home for possible safety hazards to the baby and to place one or more nicotine air monitors (small plastic objects that measure the amount of tobacco smoke in the air of each room). The home visitor returns a week late...
This study will determine the effect of combining counseling, urine cotinine feedback, and incentives in reducing environmental tobacco smoke (ETS) exposure and susceptibility to smoking among high-risk preteens.
This study is about reducing the risks of smoke-related infant health problems. Research has shown that infants exposed to secondary smoke have higher risks of delayed lung development, respiratory illnesses, wheeze, cough, asthma, middle ear disease, and sudden infant death syndrome. Infants who have experienced low birth weight or required mechanical ventilation may be at an even greater risk for the negative effects of smoking. The purpose of this study is to evaluate the effectiveness of a 3-session program aimed at assisting the primary care giver in reducing risks to their child's health by decreasing infant smoke exposure in their home and/or reducing overall cigarette use. Caregivers will not be required to quit smoking to take part in this program. This information will, in the future, help to identify and improve ways of reducing health problems and perhaps death in children.
The purpose of this study is to determine if an integrated intervention addressing active smoking, environmental tobacco smoke exposure, depression and intimate partner violence, would improve pregnancy outcome among African American women.
The purpose of this randomized control trial is to evaluate the effects of a multi-component intervention aimed at: 1. preventing tobacco initiation in youth 2. promoting anti-tobacco socialization in the home 3. decreasing environmental tobacco smoke exposure in children 4. promoting successful cessation in parent/guardian smokers. Control arm participants receive general health education. This family-based approach is implemented with school systems as the primary point of entry.
SMOKN5 is aimed at studying ways to reduce environmental tobacco smoke (ETS) for children who are being treated for cancer. The study includes St. Jude parents whose child lives with at least one adult smoker who exposes the child to ETS, also called "secondhand smoke." We are comparing two groups of parents to see which group results in lower ETS exposure levels for the child being treated with cancer. The first group will receive the standard information and advice usually given to parents about secondhand smoke. The second group will take part in a new program designed to reduce ETS. The primary objective of the study is to determine the efficacy of an environmental tobacco smoke intervention compared to the standard care control condition, as measured by parent report. Parents in each group answer questions about ETS exposure. We also collect urine samples from the child at specific time points throughout the study. The urine is tested to measure the amount of cotinine, a metabolite of nicotine. Measuring cotinine tells us how much nicotine from tobacco smoke the child has been exposed to. Children who are at least 10 years of age or older will also be asked to complete a set of questions pertaining to their tobacco use history and ETS exposure from others. This will occur at the same five time points in which the parent completes his/her portion. The study will last about 12 months for each participating family. Parents who take part in the study may learn how to lower their child's exposure to ETS, and this may, in turn, lower the child's chances of having ETS-related health problems.
A randomized, controlled, parallel group design will be used to test whether a Secondhand Smoke Exposure program initiated in the hospital and completed in the home using motivational interviewing plus motivational incentives (MI+) is more effective than Conventional Care (CC) with Neonatal Incentives Care Unit Infants' parents.
The burden of tobacco use falls disproportionately on low-income populations, through high rates of primary smoking and exposure to secondhand smoke. The remarkable progress in creating smoke-free environments in the U.S over the past two decades has left smoker's homes as one of the primary sources of exposure to secondhand smoke for both children and nonsmoking adults. Intervention research that identifies effective and practical strategies for reaching the minority of households that still allow smoking in the home has considerable potential to reduce smoke exposure, but suitable channels to reach low-income families are limited. The proposed research will systematically test an intervention designed to create smoke-free homes in low income households among 2-1-1 callers. During this randomized control trial, researchers will disseminate and evaluate a brief smoke-free homes intervention through the established infrastructure of a Texas 2-1-1 call center. 2-1-1 is a nationally designated 3-digit telephone exchange, similar to 9-1-1 for emergencies or 4-1-1 for directory assistance, that links callers to community-based health and social services. The main hypothesis to be tested is that a higher proportion of households in the intervention group will establish and maintain a smoke-free home than in the measures-only control group.
This is an unblinded pilot study of an environmental exposure to secondhand cannabis smoke in one group of healthy nonsmokers.
Asthma is one of the most common childhood diseases. It is chronic and often severely disabling. The amount of nitric oxide that is exhaled while breathing increases with airway inflammation, a symptom of asthma. This study will examine the results from a previous study, the Cincinnati Asthma Prevention (CAP) study, to evaluate the effects of environmental and genetic factors on exhaled nitric oxide (eNO) levels and to determine the relationship between eNO and asthma severity.
The purpose of this study is to examine hormonal and environmental risk factors (and possible gene-environmental interactions) involved in the etiology of lupus nephritis. Our study will focus on exposures to occupational and environmental agents that have been linked to the development of systemic lupus erythematosus (SLE) or renal disease (e.g., silica dust, smoking). We will also assess potential gene environment interactions. We will examine these exposures in 100 patients with renal biopsy with documented proliferative or membraneous nephritis. We will compare exposures in the lupus nephritis patients to lupus patients who do not have nephritis and to normal controls who have participated in the Carolina Lupus Study. One hundred lupus nephritis patients (age 18 years or older, of both genders and all races) will be identified through the Glomerular Disease Collaborative Network (GDCN) Nephropathology database and participating nephrologists at the Medical University of South Carolina, Duke University Medical Center and the East Carolina Medical School.
