NCT ID: NCT04327206 Completed - COVID-19 Clinical Trials

BCG Vaccination to Protect Healthcare Workers Against COVID-19

BRACE
Start date: March 30, 2020
Phase: Phase 3
Study type: Interventional

Phase III, two-group multicentre, randomised controlled trial in up to 10 078 healthcare workers to determine if BCG vaccination reduces the incidence and severity of COVID-19 during the 2020 pandemic.

NCT ID: NCT01043809 Completed - Infectious Disease Clinical Trials

Evaluation of a Handwashing Promotion Program in Three Countries

Start date: January 2008
Phase: N/A
Study type: Interventional

The purpose of this study is to assess whether simple, school-based handwashing promotion impacts health and hygiene knowledge among students and their families.

NCT ID: NCT00995254 Completed - Smoking Cessation Clinical Trials

Secondhand Smoke Exposure Reduction Among Young Children in China

China SHARE
Start date: September 2008
Phase: N/A
Study type: Interventional

Second hand smoking (SHS) is a health hazard to infants and children, in whom it is associated with lower respiratory tract infections, wheezing, cough, middle ear infections and sudden infant death syndrome. Evidence from developed nations suggests that measures to reduce exposure to SHS can improve children's health outcomes; this has not been systematically studied in a developing country setting. The investigators hypothesize that implementation of a package of smoking hygiene intervention measures delivered by community health workers (CHWs) will reduce Chinese children's exposure to SHS and improve their respiratory health. To test this hypothesis, the investigators have identified three specific aims: (1) to obtain baseline data on second hand tobacco exposure among young children, health status of young children and smoking status of parents and other household members, (2) to generate preliminary effectiveness data for CHW-delivered SHI, and (3) to develop culturally appropriate biochemical measures to assess children's exposure to household SHS. The investigators propose to conduct this study in an urban district in Shanghai, China. After an initial assessment, the investigators will conduct a randomized controlled trial of households in a community, selected based on important study criteria, within the district. The investigators selected this design because it is most likely to produce a scientifically valid answer to our primary study question. All eligible smokers in the intervention group will receive behavioral counseling to address health hazards of SHS towards children, brief advice to quit or to adopt a no smoking policy around children, and educational pamphlets on the hazards of SHS, from a trained CHW in their community. A questionnaire will be used for data collection at the start and at 2 and 6 months. To assess the extent of total SHS exposure, children's urine cotinine (the indicator of nicotine) level will be measured at the first contact and at 2-and 6- months. To validate household members reported level of smoking the investigators will measure air nicotine levels of a sub-sample (10%) of households via passive monitors. The results of this study will provide clinical evidence for the development of CHW-delivered interventions designed to reduce exposure to SHS and improve the respiratory health of children in a resource-poor community. If successful, the program can serve as a model for implementation in other developing country settings. Furthermore, successful results could also be used to draft guidelines for health promotion interventions, which could be implemented as a policy for all primary health care settings. Finally, the study, which would be the first of its type in a developing country setting, will form the basis for future research and program development in the area of SHS.

NCT ID: NCT00499915 Completed - Respiratory Illness Clinical Trials

NICU Asthma Education and Secondhand Smoke Reduction Study

Start date: February 2007
Phase: N/A
Study type: Interventional

Premature infants have a significantly increased risk for developing respiratory illnesses and asthma. Secondhand smoke (SHS) also is clearly associated with increased breathing problems in children, thus exposure to smoke makes it substantially more likely for a premature infant to develop wheezing. The overall goal of this study is to test whether comprehensive asthma education combined with a home-based secondhand smoke reduction program can reduce exposure to smoke and prevent respiratory illness among premature infants. Our hypotheses are: - More premature infants whose families receive asthma education combined with a SHS reduction intervention will live in smoke-free environments compared to infants receiving only asthma education (control group). - Caregivers receiving the SHS reduction program will have higher rates of quit attempts and less relapse into smoking compared to caregivers in the control group. - Infants whose families receive the combined intervention will experience less respiratory illness compared to infants in the control group.

NCT ID: NCT00437541 Completed - Asthma Clinical Trials

Housing, Insulation and Health Study

HIHS
Start date: July 2001
Phase: N/A
Study type: Interventional

In six communities we will seek out households where someone who has a history of respiratory problems. For the first winter we will measure temperature and humidity of the house and health of occupants. We will insulate half the houses and the next winter compare them with the uninsulated houses to see if warmer houses improve health.

NCT ID: NCT00421668 Completed - Respiratory Illness Clinical Trials

A Trial of Zinc and Micronutrients in Tanzanian Children

Start date: September 2007
Phase: Phase 3
Study type: Interventional

A randomized clinical trial of multiple micronutrients, zinc, zinc + micronutrients, or placebo among 2400 children born to HIV-negative Tanzanian mothers.
