7. An Epidemiological Enterprise : From Fluoride to Folate
by JD Ericson of CDC

USFDA : require fortification of folic acid
(25 states National birth defect prevention networks)

10. The All or None Phenomenon :
How should we counsel ?
By Dr. Brent
Mouse vs Human
Preimplantation period (수정 후 2주 이내)
Usually not susceptible period to teratogen
Some highly susceptible period to teratogen
Surviving embryo : similar outcome
11. 예외:
Long half life
Teratogenic infectious agent
Maternal effect(large exposure)
Epigenetic effect
Mutagenic effect
Mouse data 이용 상담 : no thanks by Brent.
12. By JM Friedman
6days : implantation begin
Very little data
Chronic exposure
Few accumulative exposure situation
Czeizel : Hofpp study
24-42days of LMP :
Exposure vs Non-exposure
Live birth 92% -
BW 3,222 3,268
Anomaly 3.3% -
14. Zygotic induced anomaly
hydrops 22%
Bent limbs 24%
Abdominal wall defect 17%
---- multifactorial birth defects
strikingly absence of other common anormaly ( NTD, CHD…)
hydrops may be pathogenic , but mechanism is unknown
Post-zygotic period :
zygote와 다름 , Death more common
Answer by JD Friedman: We don’t know
Counseling : never say : “All or none”
But, risk is very low
15. Strategies of Reducing the impact of Known teratogen
The potential benefit of a Multi-micronutrient Supplementation in

Next step “ 5세 (preschool neurobehavioral test)

developmental Neurotoxicity by KN Gale
Phenobarbital, phenytoin, lamotrigine --- neurobehavioral abnormal

Future direction : “Antidote”
Epilepsy + AED + Antidote : reduce of risk of Adverse pregnancy outcome
=== AED use 증가( more compliance)
17. Thomas Sheperd Lecture
“ The future of Research : The View of NICHD “
by AE Guttmacher (NICHD director)
NICHD : 50 yrs celebration ( 1962 : President Kennedy sign)
The mission :
every person is born healthy
women suffer no harmful effects from reproductive processes
all children have the chance to achieve their full potential for
healthy and productive lives, free from disease or disability,
health, productivity, independence, and well-being of all people
through optimal rehabilitation
18. NICHD study :
Reproduction
Developmental biology
Pregnancy : biomarker
Early origin of health and disease, growth, development
: association is not equal to mechanism
placenta , multigenerational effect
Conduct of science
trans -disciplinary science
omics( genome, epigenome)
training

20. Pregnancy registry workshop
What should pregnancy registries use for a comparison group(s)?
Pregnancy registries and REMS: opportunities for collaboration risk
(Risk Evaluation and Mitigation Strategy : to enhance labeling)
Conducting Global pregnancy registries- Challenges and opportunities
How can pregnancy registries Work with/Complement other sources of
Clinical and observational information? How does a registry fit in an
overall plan to obtain information?
Interpreting Data from pregnancy registries: Who, When, How?
21. Pregnancy registry
Advantage :
Aim of pregnancy registry : major birth defect, Birth defect trend
Used to generate hypothesis
Limitations :
Exposure의 classification - lack
Outcome(birth defect , developmental disability)의
universal determination - lack
Representation : voluntary
Loss to f/u : limit interpretation
