EPA Grant Number: R832139Center: Johns Hopkins Center for Childhood Asthma in the Urban Environment
Center Director: Breysse, Patrick
Title: Johns Hopkins Center for Childhood Asthma in the Urban Environment
Investigators: Breysse, Patrick , Matsui, Elizabet
Institution: Johns Hopkins University
EPA Project Officer: Fields, Nigel
Project Period: August 1, 2003 through July 31, 2008
Project Period Covered by this Report: August 1, 2004 through July 31, 2005
Project Amount: $4,046,103
RFA: Centers for Children's Environmental Health and Disease Prevention Research (2003)
Research Category: Children's Health , Health Effects
Description:
Objective:The objectives of the Center are to: (1) understand how exposures to environmental pollutants and allergens may relate to airway inflammation and respiratory morbidity in children with asthma in the inner city of Baltimore; and (2) develop effective strategies to reduce morbidity by changing these exposures. We proposed to address these goals with four projects:
- “Epidemiology of Susceptibly to Particulates and Allergens in Asthma” (R832139C001; Greg Diette, M.D., M.S.)—This project will examine the relationship of polymorphisms in genes encoding IL13, TLR4, and BADr to susceptibility to home pollutant and allergen exposure in asthmatic and control children.
- “A Randomized Controlled Trial of Behavioral Changes in Home Exposure Control” (R832139C002; Peyton Eggleston, M.D.)—This project will conduct a randomized controlled clinical trial of methods to increase the effectiveness of current intervention methods to reduce hazardous exposures and their adverse health effects.
- “Mechanisms of Particulate-Induced Allergic Asthma” (R832139C003; Marsha Wills-Karp, Ph.D.)—This project will examine the mechanisms by which urban airborne particulate matter (PM) may exacerbate an allergen-driven inflammatory response in the airways.
- “Dendritic Cell Activation by Particulate Matter and Allergen” (R832139C004; Steven Georas, M.D.)—This project will examine the effect of Baltimore ambient particulates on maturation of peripheral blood monocytes to dendritic cells.
The objective of the Community Outreach and Translational Core (COTC) is to create a structure to develop, implement, and evaluate strategies to translate and apply the scientific findings of the Center into information for the public, policymakers, and clinical professionals to use to protect the health of children.
The overall goal of the Exposure Assessment Core (EAC) is to provide a centralized resource for conducting exposure assessment activities related to children’s asthma research. The Core provides input into research design, field sampling equipment, and support and analytical services. The specific objectives of the Core are to: (1) collaborate in the development and conduct of epidemiologic, intervention, and exposure assessment studies; (2) facilitate the development of exposure assessment protocols; (3) provide the infrastructure necessary for conducting detailed exposure assessments; (4) assist in the design of data collection systems and the maintenance of exposure assessment databases; and (5) participate in the preparation of scientific reports and manuscripts.
The overall goal of the Data Management Core (DMC) is to provide research planning, data management, and data analysis support for the Intervention (R832139C002) and Epidemiology (R832139C001) projects.
Progress Summary:Community Advisory Board
The Community Advisory Board continued to participate actively in the Center’s activities. The Board held quarterly meetings to discuss progress in the refunding of the Center. A major activity has been the dissemination of research findings; a first meeting was held with illustrators to create a comic book and with educators to create an elementary school curriculum.
Meetings were held to create reports to the community relating environmental findings to community activities and health. It was decided that these findings would best be presented in the form of a comic book that could be distributed in many settings (health fairs, community formal lectures, school curricula). In addition, elementary school curricula and dramatic skits and plays presented by elementary school children to other children and to parents were considered.
Through the Community Advisory Board, the Center was introduced to a nonprofit organization, Baltimoreans United in Leadership Development (B.U.I.L.D.), engaged in community renewal. B.U.I.L.D. had recently completed a 650 housing unit neighborhood in Baltimore’s Sandtown-Winchester neighborhood and planned a similar project during the next 5 years in the Center’s East Baltimore catchment area. Preliminary meetings established collaborative goals that included home environmental measures in derelict buildings and longitudinal environmental measures in newly occupied B.U.I.L.D. homes. These projects are scheduled to begin in 2006.
The Community Advisory Committee met during the year to consider the Center’s funding issues and to begin planning for a community presentation of study findings. Two formats were chosen: a comic book designed by a local art institution, the Maryland Institute College of Art, which could be handed out at community organizations during presentations by study staff. In addition, a teacher with middle school experience offered to help script skits by elementary school children to present the study findings in an interesting, engaging format.
Administrative Core
The Administrative Core is responsible for fiscal and administrative policy and reports, for scheduling meetings, maintaining records of all Center meetings, arranging meetings, and creating progress reports. This office arranges the biweekly research conferences, as well as meetings of the Outside Advisory Committee, the Internal Advisory Committee, and the Community Advisory Committee. The unit also arranges for Center personnel to attend annual program meetings. The creation of any public communications originates from this office. The newly recruited faculty program is administered through this Core, although the selection of the scientist is conducted by a committee that has no conflict of interest.
Difficulties and Remedial Action. Most activities of the Administrative Core were delayed in Year 2 of the project because of the delay in funding from the sponsors. Full funding for Year 2 was not received until May 2005. During the period until May 2005, the Administrative Core ensured that ongoing projects such as the Epidemiologic Study (R832139C001) were completed, ensured that Center personnel who were considered nonessential were reassigned to other projects, and that those considered essential, such as the DMC and EAC, were supported while the Center’s projects were completed and publications created. Communication with the External Advisory and the Community Advisory Committees was maintained with periodic meetings or written communication so that they were apprised of the Center’s activities and the status of funding. Finally, the research conferences were continued because the cost was minimal, and they contributed to the morale of the Center personnel.
Community Outreach and Translational Core
Center key personnel continued to participate in community outreach and translational education. A report from the Medical Director at the Center of Maternal and Child Health, Maryland Department of Public Health describing current asthma health statistics as well as environmental measures has been widely distributed.
Several members of the Center’s medical staff are actively involved in medical education with local physicians, nurses, and other health care workers. During the past year, these individuals have presented environmental data and recommendations at continuing medical education courses on asthma and have presented at more than 20 staff meetings of local health care providers. Dr. Eggleston will participate in a regional educational meeting on children’s health and the environment to be conducted at the Mid-Atlantic Center for Children’s Health and the Environment located at George Washington University and sponsored by the State of Maryland and U.S. Environmental Protection Agency Region 3.
Dr. Eggleston was appointed to the Maryland Governor’s Children’s Environmental Health and Protection Advisory Council, an advisory committee charged with ensuring that the State environmental protection laws and regulations accounted for children’s environmental health issues. During the past year, the Council continued its review of school’s policies to evaluate and remediate mold in school buildings.
Most activities of the Community Outreach Core were delayed in Year 2 of the project because of the delay in funding from the sponsors. Full funding for Year 2 was not received until May 2005. Communication with the Community Advisory Committees were maintained with periodic meetings or written communication so that they were apprised of the Center’s activities and the status of funding.
Exposure Assessment Core
Collection of Bulk PM. The EAC has negotiated successfully with the Maryland Tunnel Authority to place two cyclone samplers in the air plenum above the two northbound tubes of the Fort McHenry Tunnel. Sample collection has been ongoing for more than 3 months and more than 1g of PM has been collected from each tunnel; PM characterization studies are being planned.
PM collection on the roof of the Johns Hopkins School of Public Health has been ongoing since June 2005. These samples will be characterized and analyzed in the laboratories of Dr. Wills-Karp and Dr. Georas.
The EAC has explored the use of a multistage low volume cyclone cascade system for the collection of size-selected PM samples.
The EAC also is developing a collaboration with the Applied Physics Laboratory to gain access to a multistage sequential drum sampler for possible use in PM characterization in tunnel, homes, and ambient air.
Interaction With the DMC. The EAC continues to work with DMC on the data quality control, data summarization, and manuscript preparation. One manuscript has been published to date.
Interaction With the COTC. The EAC has participated in COC meetings and currently is assisting in the development of strategies for informing the community about results of Center activities conducted under a previous grant (EPA Agreement No. R826724).
Development of New Analytical Methods. A sampling and analytical method for nicotine in hair to be used as a biomarker of environmental tobacco smoke exposure has been developed and is being validated.
Methods for characterization of endotoxin and other biogenic components of settled and airborne PM are being developed.
Data Management Core
In addition to maintenance of the data management system, the DMC has provided data support services for both the epidemiologic and intervention studies, providing interim and final analyses of accumulated data and participating in the preparation of scientific reports and manuscripts.
The DMC holds weekly meetings with investigators and research staff of the Center to present reports of interim analyses, troubleshoot data collection or quality issues, and provide a forum for discussions regarding abstract and manuscript preparation. To help organize conflicting data requests from the numerous manuscripts in preparation, the Core developed and established a written Data Analysis Request and Dataset Request procedure.
In addition to the weekly meetings, the DMC created a tracking/recruiting database for the Epidemiologic Study (R832139C001) to facilitate collection of genetic samples from families that completed the initial protocol 1 to 2 years earlier.
The DMC created a recruiting database and secured human subject approval by the Johns Hopkins Institutional Review Board. This database consisted of the names and demographic data for all families who have participated in studies conducted by the Center investigators, including but not limited to those the intervention and epidemiologic studies described in this report.
The DMC collaborated with the laboratories in the Environmental Core. The allergen support laboratory developed a data collection and management system for allergen data with a data entry system that includes QC features that link data entry from the allergen lab to the study databases. The Environmental Core laboratory developed a data entry system that links data entry from the Environmental Core laboratory to the main study databases. Written procedures were created for each newly developed data entry system or database to be added to the Manual of Procedures.
In addition to supporting the Center activities, the DMC assists the Center investigators with data analysis for two other National Institutes of Health (NIH)-sponsored clinical trials whose aims and activities overlap with those of the Center. These projects include the ICART, a controlled clinical trial of the efficacy of cockroach allergen abatement in inner-city families, and the HOME, a controlled clinical trial of allergen reduction in suburban and inner-city homes. In addition, a combination of NIH and private funding support the DMC assistance in database development, data management, and data analyses for the JAX Cohort study, a prospective cohort study of newly employed laboratory animal workers.
Research Conferences
The Center’s research conferences have been presented throughout the year. In addition to several speakers from the University and from the Center staff, we have invited speakers from other centers and projects to discuss work that related to the Center’s goals.
Future Activities:The Administrative Core will continue to be responsible for fiscal and administrative policy and reports, for calling meetings, for maintaining records of all Center meetings, and for arranging meetings and creating progress reports. This office will arrange the biweekly research conferences, as well as meetings of the Outside Advisory Committee, the Internal Advisory Committee, and the Community Advisory Committee. The unit will continue to arrange for Center personnel to attend annual program meetings. The creation of any public communications will originate from this office. The newly recruited faculty program is administered through this core, although the selection of the scientists is conducted by a committee with no conflicts of interest.
The formats for community presentation of research findings will be completed.
Research projects established in preliminary discussions with B.U.I.L.D. will be developed and carried out in accordance with the Center’s research agenda.
During the coming year, we will recruit a full time Community Outreach Coordinator and will proceed with the activities outlined in our original proposal. These include:
- Continued meetings of the Community Advisory Committee with its full membership. The committee will help recruit the Community Outreach Coordinator, will advise concerning the needs and performance of the school-based asthma education program, and will oversee our involvement with the East Baltimore development initiative. Finally, the committee will continue to serve as a forum for identifying the community’s needs and resources, in addition to advising on our study design.
- School-based asthma education. The Community Outreach Coordinator will continue the school-based asthma self management classes (A+ Asthma Club) in the six elementary schools selected during the past 4 years.
- Facilitation of healthy housing in East Baltimore. The Coordinator will begin to engage B.U.I.L.D., an organization dedicated to the creation of owner occupied low-cost housing in Baltimore. The organization already has succeeded in creating more than 600 units in West Baltimore and is interested in doing the same in East Baltimore; the Center’s role will be as a consultant and resource to this process. Through our own studies, we understand that asthmatic health is adversely affected by water damaged homes and those infested by cockroaches and mice. Through our clinical trial of environmental intervention in asthma, we can provide preliminary recommendations of specific activities to reduce exposures to specific environmental agents that can improve the health of asthmatic patients. We will be able to provide policy planning, free housing inspection and evaluation, and housing advocacy.
- Health fairs. Center personnel will continue to participate in health fairs sponsored by churches, schools, and other community organizations in East Baltimore. The Coordinator will be responsible for coordinating these activities, recruiting Center personnel, arranging for the presence of the Center’s educational poster board, educational brochures, and soliciting donations of peak flow meters and allergen-proof encasings to be distributed at the fairs.
- Community meetings. The Community Outreach Coordinator will be the Center’s representative at local meetings of neighborhood organizations. As the need arises other Center personnel will be called upon to attend these meetings and to participate in faith-based activities relating to asthma care.
- Health care workers educational activities. Center investigators and staff will continue to participate in educational sessions with local health care workers. These usually take the form of continuing medical education lectures presented in events sponsored by the Johns Hopkins medical institutions or by health care organizations. We anticipate that 5-10 events will occur annually.
- Community focus groups. The Center will continue to hold community focus groups to better understand the issues, attitudes, and needs of community members with regard to asthma and local environment. These groups have been organized in the past by staff from the epidemiology component. During the next year, they will be involved only in an advisory capacity.
- The Center in Urban Environmental Health. The Center includes a Community Outreach and Education Program, headed by Michael Trush, Ph.D. Center investigators and staff from the Children’s Center will continue to participate in the Urban Environmental Health Center’s Environmental and Community Health Course for graduate students. We also will participate in the summer institutes and the Earth Day activities.
The DMC will continue its present activities with an emphasis on interactive databases to facilitate the integration of the laboratory support for the Epidemiology and Intervention trial components. In addition, data set preparation and data analysis activities will continue for the Intervention and the Cohort study components.
The EAC will continue its present activities. As the Intervention and Cohort studies progress to completion, we anticipate that the environmental measurement load will decrease and data analysis activities will increase. In addition, we will be assisting in preparing publications of study findings.
