Description:
Objective:The unifying theme of the Center for Childhood Neurotoxicology and Assessment is to determine the influence of exposure to neurotoxicants on child neurological health and development, with autism and related learning disabilities as a focus. The objectives of the Center are to detect, understand, and prevent environmental health problems as they relate to children. These objectives are achieved by facilitating interdisciplinary research, enhancing community and advocacy group involvement, and disseminating results to the public through publications, conferences, and community outreach.
The multidisciplinary research of the Center is based on three main project areas. The Basic Sciences Projects examine facets of brain development, beginning with neurogenesis and proceeding through to behavior in the intact animal. The Clinical Sciences Projects are interactive with community groups representing children with learning disabilities and their families, with particular emphasis on autism. These projects explore the linkage between environmental neurotoxicants, clinical course of autism, regional brain growth, and a possible new gene-environment interaction with autism. The Exposure Assessment and Intervention Project (EAIP) will characterize the personal, residential, and general community of exposure of children selected by the Clinical Sciences Projects. The EAIP then will determine the need for interventions to reduce neurotoxicant exposure among learning-disabled children and assess the impact of such interventions. The Exposure Assessment Facility Core will provide innovative video techniques to assess the relationship between the behavior of the child with autism and his/her potential to contact with neurotoxicants. The overall mission of the Center is to improve environmental and public health of children through research, assessment, treatment, and outreach.
The objectives of the Administrative Core are to: (1) coordinate the individual studies so they are interactive; (2) recruit additional faculty whose research greatly compliments the five core projects, including supporting the Center’s new research faculty in environmental health; (3) assure collaborative relationships with the autism community of New Jersey and other states; (4) reach out to the federal government in various ways to educate and coordinate efforts regarding children and environmental health, particularly children with neurobehavioral issues; and (5) submit Center-related grants to the National Institute of Environmental Health Sciences (NIEHS).
Progress Summary:The Center has flourished with exciting results that have led to clinically relevant findings regarding autism, gene environment interaction, and developing potential therapeutic/preventive measures through development and validation of neuroprotective agents. This research output is being developed and focused through the collaborative Translational Research Group that has been developed within the Center with basic and clinical scientists and key additional research faculty that have joined the Center and the Translational Research Group.
This Group and the Center consist of a core of multidisciplinary researchers and focus on improving the health of children with autism in at least ameliorating the clinical course of autism but eventually decreasing the incidence of autism. The research has begun to elucidate not only neurodevelopmental issues in children with autism but also will expand the knowledge base of neurodevelopmental and toxicological sciences in humans and animals.
Center’s Research Focus – Following the Direction of the Autism Research Findings
The Center’s main focus continues to be autism and gene environment interaction. The major findings of the Center are focused on the gene environment interaction, the apparent increased susceptibility of the child with autism to oxidative stress (see the 2006 Annual Report for R829391C005), and developing intervention strategies to provide increased antioxidative capacity to the child based on our animal models and the development of new knockout mice that mimic the human condition (see the 2006 Annual Report for R829391C005). As will be seen, this area holds great promise for understanding and hopefully prevention of autism and is the overriding focus of autism research in the future. This does not exclude related autism and environmental research.
In regards to current environmental chemical levels in the children with autism, our preliminary research is revealing that the child with autism does not have markedly exaggerated levels of environmental chemicals in their body, nor does the child with regression have markedly increased levels of at least the heavy metals. These data are from the first 50 children and may change as we finish recruiting the entire cohort of 100 children. Also, as some investigators have suggested, the children’s environmental levels may not be exaggerated greatly and may not be higher than the control population. Final determination of that will await completion of the cohort and comparison to statewide and national data sets such as the National Health and Nutrition Examination Survey (NHANES).
One-third of the homes, however, do have areas of environmental concern. We have demonstrated that with individually developed intervention strategies, the home levels of a wide variety of home environmental chemicals can be reduced remarkably. What we have learned is that the parents in our study have little information on how to reduce the amounts of environmental chemicals in the home and which interventional strategies are the most effective. The parents are very concerned and somewhat aggravated that they were not made aware of this information years before; this is clearly a public health need.
Other Known Autism Related Research – Relevant Output and Outcome of the Center
The presence of the Center has drawn other research collaboration into the area of children’s environmental health. These areas have included clinical studies with phthalates in newborns, polychlorinated biphenyl (PCB) exposure to human health and cytochrome P450 function, and the pharmacokinetic-pharmacodynamic (PKPD) properties of perchlorate. The outcome of at least one study is impacting how humans are exposed to plasticizers in hospitals. The phthalate study is being used in many hospital settings as a reason to change the type and manufacturing of plastic devices used in the hospital setting to no-phthalate plastics. The Center is entering into research agreements with selective manufacturers to develop new manufacturing processes of hospital plastic equipment and monitor plasticizer exposures. Several researchers are working to establish a linkage between phthalates and neurodevelopment, and the Center has entered an agreement with the Danish Institute of Technology to study phthalate gene interaction in children with asthma in Scandinavian countries.
This report presents the Administrative Core and overall Center activities; progress on each of the five projects is presented in the individual 2006 Annual Reports for R829391C001 through R829391C005.
Administrative Core
Center Membership. We have expanded the Center membership with additional faculty with special interests that complement current and future Center activities. The new faculty includes Dr. Peter Stein and his co-investigator Dr. Terry Sholz, who have a long history of National Institutes of Health (NIH) studies of human oxidative stress in the perinatal period and developmental outcome of the pregnancy and the child; Dr. Arnold Levine, who studies P53 and related genes; and Dr. Walter Zahorodny who is the principal investigator on the University of Medicine and Dentistry of New Jersey (UMDNJ) and Centers for Disease Control and Prevention health tracking of autism grant. Dr. Oleg Mirochnitchenko, who has great expertise in animal models and oxidative stress, will help characterize the new oxidative stress knockout mouse.
Center Research Meetings. Center meetings include weekly translational research meetings, weekly clinical research meetings, semiannual intramural director’s meetings, and the annual External Advisory Committee meeting. In addition, the Center has selectively invited guest speakers just for the Center’s core research group and the Center also co-sponsors several monthly research seminars.
A most productive and exciting meeting is the weekly translational research meeting. This meeting is held at the Center but on occasion is held by the Center faculty at the Newark Medical School of UMDNJ (Dr. Ming as host) and the Stratford, New Jersey, campus of the UMDNJ School of Osteopathic Medicine (Dr. Stein as host). The meeting is well attended primarily by the neurogenetics investigators, the oxidative stress groups, the pediatric environmental toxicology groups, and the animal pharmacology/animal modeling groups of Drs. Wagner and Ming. These are held weekly and focus on oxidative stress, preventive antioxidant therapies, animal modeling, and development of critical knockout mice. The synergistic, interactive, and cooperative atmosphere of this meeting is truly remarkable and exciting to all. This is demonstrated by the fact that many of the faculty travel several hours each from their laboratories to attend each meeting. One week per month there is a journal club based on neurogenetics and autism and oxidative stress. This also is well attended by faculty and graduate students.
The clinical studies groups meet weekly to discuss subject recruitment, subject tracking through studies, home intervention, retesting of subjects and homes, and family communications.
The intramural advisory group meets two or three times per year. This group has consisted of Drs. Lambert, Reuhl, and Lioy. Because the major focus of the research is expanding to encompass oxidative stress, this advisory group is being changed to include animal modelers and neurogenetics faculty.
The External Advisory Committee last met May 2004 at UMDNJ. This year, because of the need to competitively resubmit the Center application in response to the new Request for Applications (RFA), the External Advisory Committee will meet in September to mark the Center’s progress, advise on the resubmission strategy, and comment on P50 grants that will be submitted in mid-October. Because of the focus on animal modeling, stress, and clinical studies, Dr. Susan Schantz from the University of Illinois and the Director of the Friends Children’s Environmental Health Center has been added to the advisory group.
Center’s Outreach to the Autism Community. The Center and its investigators have become integrally involved with the autism community in various ways. The Center members and especially Dr. Lambert present information about the Center and the Center’s research and discuss the interaction between environmental chemicals and children, especially children with autism, on a regular basis to hospital-based families with autism and autism support advocacy groups such as The New Jersey Center for Outreach and Services for the Autism Community (COSAC), National Alliance for Autism Research (NAAR), and the Autism Society of America (ASA). The Center works with NAAR to raise funds for research and has won several awards from NAAR for its stellar fundraising. The attendance of the meetings where Center members present autism and environment issues is large: 1,450 parents and health care professionals attended this year’s COSAC annual meeting, 200 parents attended the NAAR Tri-State Support and Research Group meeting, and the ASA annual research meeting held in Indianapolis, Indiana, was attended by more than 600 parents and health care professionals. This year, Dr. Lambert talked to more than 3,000 parents about environmental pediatric health and autism. The Center has become an important part of the autism community in New Jersey and is very interactive with the national and the greater mental retardation community.
Center Outreach to the Scientific Community. The Center has published 25 papers this year and many abstracts. The Center members participated in the Children Centers’ Symposium held at the Meeting of the International Society of Environmental Epidemiology and other scientific meetings. Dr Lambert served on the National Academy of Sciences Committee on the Health Effects of Perchlorate with the findings published in January 2005. Dr Lambert currently serves on the Science Advisory Board (SAB) of the U.S. Environmental Protection Agency (EPA) and as the liaison from the SAB to the Board of Scientific Counselors (BOSC) of EPA’s Office of Research and Development. Dr. DiCicco-Bloom is a member of the scientific board of NAAR.
Center members, Drs. Johnson (neurogenetics), Ming (oxidative stress), and DiCicco-Bloom (neurogenesis) have received outside funding for their autism work of more than $1 million of direct costs this year from NIH and the New Jersey Governor’s Council on Autism. In addition, Dr. Lambert has received extramural funding to host an annual science and autism day just before the annual COSAC conference, which is the largest conference on autism in the country. The purpose of this event is to bring together the scientific and parent community in the Northeast and Central Atlantic regions to develop synergistic, cooperative, and translational research in autism. The Center has applied for a National Institute of Environmental Health Sciences (NIEHS) training grant.
Center Outreach to Government – The Impact. The investigators believe that a function of the Center should be to provide scientific information to governments at all levels so that the government can make public health decisions based on the best available science. Dr. Lambert has advised governors and state legislators on mercury, perchlorate, and the National Children’s Study. In fact, New Jersey passed the most rigid mercury emissions laws in the country primarily based on health concerns of children.
Dr. Lambert with Congressmen Saxton and Holt from New Jersey organized a Congressional Children’s Environmental Health Caucus (CEHC). The purpose of the Caucus is to provide Congress, on an as-needed and regular basis, scientific information on children’s environmental health. To date, the CEHC is 1 year old, has 30 members of Congress from 10 states and the Virgin Islands and held its first semiannual briefing and Congressional luncheon in May at the Capitol. Several members of Congress, including Congressional leaders Saxton and Holt, attended the briefing, along with 75-100 legislative assistants. The topic was the National Children’s Study. This is a scientific advisory caucus and not a lobbying caucus. Twenty to 30 other members of Congress have expressed interest in the CEHC, and the ultimate goal is to gather more than 200 members from both sides of Congress.
In addition, Dr. Lambert was asked by Congresswoman Solis to participate in her perchlorate briefing on the Hill. Dr. Lambert presented the Center’s Research at the NIEHS Executive Council in Research Triangle Park, North Carolina, and the BOSC 5-year Review of Extramural Human Health Research Program.
Center Awards. The Center and its members received several awards and honors. The Center received an award from NAAR indicating the Center was the third most successful group in raising funds for NAAR research. Dr. Lambert received the “Health Care Professional of the Year Award” from the COSAC at their annual convention. Other awards this year were from CNBC and the Governor of New Jersey. Dr. Lambert was appointed to the New Jersey Governor’s Council on the Prevention of Mental Retardation and gave a keynote address at the Council’s 20-year celebration.
The paper published on phthalates in newborns was selected to be considered for the Charles C. Shepard Science Award for the best scientific paper from the CDC for the year 2004 and is up for the best paper of the year award from the CDC.
Center Outreach to Government and Industry. The Center is partnering with the National Institute of Childhood Health and Human Development and the National Multi-Center MRI Study of brain development in normal children. We will compare the MRI images from our children with autism to their MRI volumetric assessment of regional brain growth in the normal child. This will allow us to have a comparison between the child with and without autism. We have implemented their MRI methods and our MRIs have passed their review for quality assurance allowing us to compare to their database and visa versa.
In addition, the Center’s research has lead to the development of collaborative efforts between the Center and several biotechnology leaders. The Center has begun working with Siemens Corporation Research Institute’s imaging and bioinformatics groups (Intelligent Vision and Reasoning Division) in Princeton, New Jersey. The Corporation has begun to develop enhanced integrative models for volumetric and regional specific measurements and mylinations. These measurements will be used to analyze our volumetric and functional MRI. They already have begun their developmental research using our MRIs. In addition, the collaborative group has agreed to try to develop mass spectral analysis of specific environmental chemicals from the spectral MRI we will collect.
The Center entered into a confidentiality agreement to work with Becton Dickerson and Company in the development and clinical assessment and exposure of no-phthalate containing medical supplies that are used in and around hospitals. Finally, the Centers’ Translational Research Group has begun to talk with the pharmaceutical companies in an effort to develop joint efforts in the development of interventional/preventive strategies to ameliorate or prevent autism using our Translational Research Group and animal and clinical studies. Center investigators have an approved patent for this approach to therapeutic intervention in autism.
Summary
The Center’s research, activities, and function have provided a focus of synergistic and interactive research for the autism community, scientists, and governments. There already have been tangible outputs and altered outcomes as a result of the research.
