RESUMO
BACKGROUND: The aim of this study was to assess psychological/psychiatric problems and quality of life (QOL) in patients with thalidomide embryopathy (TE), with a specific focus on pain, including pain severity and the effects of coping strategies for pain. METHODS: A questionnaire survey was conducted to evaluate the severity of pain experienced by patients with TE, pain management strategies, time perspective, mental health status, and QOL. Of 67 patients with TE who underwent a health checkup, 51 respondents who gave valid responses were included in analysis. RESULTS: GHQ-28 suggested that 41.2% of respondents appeared to potentially have psychiatric disorders. The mean scores of QOL were still within a normal range. There is no significant differences were found between limb disability group and hearing impairment group in QOL or mental health status. About 82.4% of respondents reported that they experience physical pain, and the use of the cognitive coping strategy "catastrophizing" to cope with pain was significantly associated with mental health status and QOL. CONCLUSION: This study demonstrate that although some patients with TE have some form of mental health problem, they still maintain a normal range QOL despite their disabilities. In addition, pain was not as strongly associated with mental health problems and QOL as would be expected, and variables such as "catastrophizing" to cope with pain appear to potentially be associated with reduced mental health and QOL.

PURPOSE OF REVIEW: We review data on the comparative teratogenicity of antiepileptic drugs (AEDs), focusing on major congenital malformations (MCMs), intrauterine growth restriction, impaired cognitive development, and behavioral adverse effects following prenatal exposure. RECENT FINDINGS: Prospective registries and meta-analyses have better defined the risk of MCMs in offspring exposed to individual AEDs at different dose levels. Valproate is the drug with the highest risk, whereas prevalence of MCMs is lowest with lamotrigine, levetiracetam, and oxcarbazepine. For valproate, phenobarbital, phenytoin, carbamazepine, and lamotrigine, the risk of MCMs is dose-dependent. Prenatal exposure to valproate has also been confirmed to cause an increased risk of cognitive impairments and autistic traits. In a population-based study, the risk of AED-induced autistic traits was attenuated by periconceptional folate supplementation. SUMMARY: The risk of adverse fetal effects differs in relation to the type of AED and for some AEDs also the daily dose. Although for MCMs the risk is primarily associated with the first trimester of gestation, influences on cognitive and behavioral development could extend throughout pregnancy. Available information now permits a more rational AED selection in women of childbearing potential, and evidence-based counseling on optimization of AED treatment before conception.

OBJECTIVE: To confirm the current state of Japanese women's perception of the teratogenic risk of medication exposure during pregnancy, and to assess the effect of counseling byãJapan Drug Information Institute in Pregnancy. METHODS: We used VAS to monitor the sentiments of pregnant women, before and after face-to-face counseling, about their own teratogenic risk perception, and their intention to continue pregnancy. Pregnancy outcomes were investigated by mailed questionnaires. RESULTS: Among 681 pregnant women, the median estimation of the risk of having a baby with a birth defect was 33.0% (interquartile range 16.0-50.0%) prior to counseling and 5.0% after counseling (2.0-11.0%). The median intention to continue pregnancy increased from 86.0% to 100.0% after counseling. The actual outcome survey revealed that almost all participants (97.1%) continued their pregnancies. CONCLUSIONS: Pregnant women tend to overestimate the fetal risks of medication exposure during pregnancy. Counseling would prevent unnecessary termination.

PURPOSE: To critically review pregnancy-induced pharmacokinetic changes and their clinical application. METHODS: Structured review of Pubmed, MBASE and published books. RESULTS: For many drugs, advanced pregnancy is associated with lower maternal serum concentrations. As most drug concentrations are not measured routinely, such changes are not evident to the clinician. Moreover, even for drug concentrations measured clinically, one cannot interpret lower total drug levels as evidence of lower fraction of free drug, which is the pharmacologically- active component, due to lower protein binding of many drugs in late pregnancy. Higher fractions of free drug will lead to higher rate of hepatic metabolism, especially for high extraction medications, leading to lower total drug concentrations.. Pregnancy- induced larger volume of distribution will lead to lower peak of drugs and hence may impact the achievement therapeutic levels. To further complicate matters, the adherence of many women decreases during pregnancy, mostly due to fears of adverse fetal effects. These dynamic and complex processes make changes in recommendations for dose schedule very challenging and in many cases not practical. CONCLUSIONS: Indeed, there are presently no pregnancy- targeted dose schedules, similar to existing dose changes, for example, in renal failure. Similar to the recent increased attention given to pharmacokinetic changes in pregnancy, well designed studies should compare dose-effect relationships in women receiving medications in different stages of pregnancy, to women receiving the same drug before, and/or after pregnancy. Whenever possible, women with chronic conditions can serve as their own controls and decrease the uncertainty created by inter- patient variability. Measuring drug effects in parallel to drug concentrations, will allow pharmacokinetic- pharmacodynamic modelling, leading to evidence-based decisions regarding changes in dose schedules during gestation.

AIMS AND OBJECTIVES: The primary aim was an evaluation of the pattern of gross congenital malformations in a rat model of autism spectrum disorder (ASD) and the secondary aim was characterization of the most common gross malformation observed. MATERIALS AND METHODS: In females, the late pro-oestrous phase was identified by vaginal smear cytology, and then, they were allowed to mate at 1:3 ratio (male: female). Pregnancy was confirmed by the presence of sperm plug in the vagina and presence of sperm in the vaginal smear. In the ASD group, ASD was induced by injecting valproic acid 600 mg/kg (i.p.) to pregnant female rats (n = 18) on day 12.5 (single injection). Only vehicle (normal saline) was given in the control group (n = 12). After delivery, pups were grossly observed for congenital malformations until the time of sacrifice (3 months) and different types of malformations and their frequency were noted and characterized. RESULTS: In the ASD group, congenital malformation was present in 69.9% of the pups, whereas in the control group, it was 0%. Male pups were most commonly affected (90% in males vs. only 39.72% in female pups). The tail deformity was the most common malformation found affecting 61.2% pups in the ASD group. Other malformations observed were dental malformation (3.82%), genital malformation (3.28%) and paw malformation (1.1%). Hind limb paralysis was observed in one pup. The tail anomalies were characterized as per gross appearance and location of the malformation. CONCLUSION: In this well-validated rat model of ASD, congenital malformation was quite common. It seems screening of congenital malformations should be an integral part of the management of ASD, or the case may be vice versa, i.e., in the case of a baby born with a congenital deformity, they should be screened for ASD.

BACKGROUND: Between 1957 and 1962 thalidomide was used as a nonaddictive, nonbarbiturate sedative that also was successful in relieving the symptoms of morning sickness in early pregnancy. Infamously, thousands of babies were subsequently born with severe birth defects. The drug is used again, today, to successfully treat leprosy, and tragically, there is a new generation of thalidomide damaged children in Brazil. While the outward damage in babies has been documented, the effects of the damage upon the survivors as they grow up, the lifestyle changes and adaptations required to be made, as well as studies into ageing in survivors, has received little attention and remains understudied. METHODS: A unique multidisciplinary meeting was organized at the University of York bringing together thalidomide survivors, clinicians, scientists, historians, and social scientists to discuss the past, the current and the future implications of thalidomide. RESULTS: There is still much to learn from thalidomide, from its complex history and ongoing impact on peoples' lives today, to understanding its mechanism/s to aid future drug safety, to help identify new drugs retaining clinical benefit without the risk of causing embryopathy. CONCLUSION: For thalidomide survivors, the original impairments caused by the drug are compounded by the consequences of a lifetime of living with a rare disability, and early onset age-related health problems. This has profound implications for their quality of life and need for health and social care services. It is vital that these issues are addressed in research, and in clinical practice if thalidomide survivors are to "age well". Birth Defects Research 109:296-299, 2017. © 2017 Wiley Periodicals, Inc.

BACKGROUND: Estimating the true risk of fetal malformations attributable to the use of medications is difficult and perception of risk by health professionals will impact their counseling and treatment of patients who need medication during pregnancy. The objective of this study was to assess the perception of the teratogenic risk of 9 commonly and 3 rarely prescribed drugs among general practitioners and specialists in obstetrics/gynecology. METHODS: All 811 general practitioners in the Region of Southern Denmark and all 502 specialist obstetricians/gynecologists in Denmark as a whole were invited to participate in the study based on an online questionnaire. Medians and interpercentile ranges of the perceived background risk and perceived risks for each of the drugs were included in the questionnaire. RESULTS: One hundred forty three (18 %) general practitioners and 138 (27 %) obstetricians/gynecologists participated. Estimates provided by the participants were generally in accordance with current knowledge of drugs with established safety during pregnancy. Perceptions of risks associated with warfarin and retinoid exposure were severely underestimated. CONCLUSIONS: Understanding of teratogenic background risk and specific risks associated with in utero exposure to 12 different drugs generally approached the established knowledge. The risk associated with warfarin and retinoid exposure was severely underestimated by both groups of health care professionals, while general practitioners specifically overestimated the risk of sertraline and citalopram to some extent. In Denmark, general practitioners can prescribe antidepressants, and even minor misconceptions of the teratogenic potential of citalopram and sertraline may be of clinical relevance. In Denmark, systemic retinoids can only be prescribed by a dermatologist, and warfarin treatment is only rarely initiated in women of the fertile age without involvement of specialists in internal medicine. Hence, the active knowledge on the teratogenic potential of these drugs is likely to be less accurate among general practitioners and obstetricians/gynecologists; although still of clinical importance since these specialists are largely involved in the counselling of pregnant women.

"Psychopharmacoteratophobia is the fear or avoidance of prescribing psychotropic medicine to a pregnant woman on a given indication in anticipation of fetal malformation." It is rooted in the tragedy associated with thalidomide use and is increasing due to the inability to predict accurately, strict legal provision of consumer protection, ethical and legal issues involved, and pitfalls in the available evidence of teratogenicity. In the Indian setting, the physicians face more challenges as the majority of the patients may ask them to decide, what is the best for their health. Most guidelines emphasize more on what not to do than what to do, and the locus of decision is left to the doctor and the patient. In this review, we have focused on relevant issues related to psychopharmacoteraophobia that may be helpful to understand this phenomenon and help to address the deprivation of a mentally ill woman from the required treatment.

Organophosphate flame retardants (OPFRs) are common replacements for the phased-out polybrominated diphenyl ethers (PBDEs) and have been detected at high concentrations in environmental samples. OPFRs are structurally similar to organophosphate pesticides and may adversely affect the developing nervous system. This study evaluated the overt toxicity, uptake, and neurobehavioral effects of tris (1,3-dichloro-2-propyl) phosphate (TDCPP), tris (2-chloroethyl) phosphate (TCEP), tris (1-chloro-2-propyl) phosphate (TCPP), and tris (2,3-dibromopropyl) phosphate (TDBPP) in early life stage zebrafish. Chlorpyrifos was used as a positive control. For overt toxicity and neurobehavioral assessments, zebrafish were exposed from 0 to 5 days postfertilization (dpf). Hatching, death, or malformations were evaluated daily. Teratogenic effects were scored by visual examination on 6 dpf. To evaluate uptake and metabolism, zebrafish were exposed to 1 µM of each organophosphate (OP) flame retardant and collected on 1 and 5 dpf to monitor accumulation. Larval swimming activity was measured in 6 dpf larvae to evaluate neurobehavioral effects of exposures below the acute toxicity threshold. TDBPP elicited the greatest toxicity at >1 µM. TDCPP and chlorpyrifos were overtly toxic at concentrations ≥10 µM, TCEP, and TCPP were not overtly toxic at the doses tested. Tissue concentrations increased with increasing hydrophobicity of the parent chemical after 24 h exposures. TDCPP and TDBPP and their respective metabolites were detected in embryos on 5 dpf. For all chemicals tested, developmental exposures that were not overtly toxic significantly altered larval swimming activity. These data indicate that OPFRs adversely affect development of early life stage zebrafish.

OBJECTIVE: Investigate the association between health literacy and perception of medication risk, beliefs about medications, use and non-adherence to prescribed pharmacotherapy during pregnancy, and whether risk perception and beliefs may mediate an association between health literacy and non-adherence. METHODS: This multinational, cross-sectional, internet-based study recruited pregnant woman between 1 October 2011 and 29 February 2012. Data on maternal socio-demographics, medication use, risk perception, beliefs, and non-adherence were collected via an on-line questionnaire. Health literacy was measured via a self-assessment scale. Mann-Whitney U test, Spearman's rank correlation, Generalized Estimating Equations and mediation analysis were utilized. RESULTS: 4999 pregnant women were included. Low-health literacy women reported higher risk perception for medications, especially penicillins (Rho: -0.216) and swine flu vaccine (Rho: -0.204) and more negative beliefs about medication. Non-adherence ranged from 19.2% (high-health literacy) to 25.0% (low-health literacy). Low-health literacy women were more likely to be non-adherent to pharmacotherapy than their high-level counterparts (adjusted OR: 1.30; 95% CI: 1.02-1.66). Risk perception and beliefs appeared to mediate the association between health literacy and non-adherence. CONCLUSION: Health literacy was significantly associated with maternal health behaviors regarding medication non-adherence. PRACTICE IMPLICATIONS: Clinicians should take time to inquire into their patients' ability to understand health information, perception and beliefs, in order to promote adherence during pregnancy.

AIM: The aim of the study was to examine the presence of psychological and mental health problems in patients with thalidomide embryopathy in Japan in order to develop and build future support systems. METHODS: The present study examined the presence/absence of electroencephalographic abnormalities, intellectual/cognitive functions, and mental health problems in 22 participants (nine men, 13 women) with thalidomide embryopathy. Participants completed the electroencephalograph instrument. Participants were also assessed using the Wechsler Adult Intelligence Scale-III; the Autism-Spectrum Quotient; the General Health Questionnaire-28, and the Mini-International Neuropsychiatric Interview. RESULTS: The results suggest the following: (i) electroencephalographic abnormality observed in several thalidomide embryopathy participants is unlikely to be the direct result of thalidomide; (ii) the cognitive functions of working memory and processing speed are lower in thalidomide embryopathy patients than in healthy individuals; and (iii) 40.9% of the thalidomide embryopathy participants have possible mental disorders, with more mental problems observed than in healthy individuals. CONCLUSIONS: Deterioration of mental health in patients with thalidomide embryopathy is indicated. Anxiety, insomnia, and physical symptoms were especially remarkable and may have resulted in restriction of social activities. Therefore, careful examination and active support of patients' psychological and mental problems is essential.

O manejo da terapia medicamentosa em unidade de terapia intensiva neonatal é complexo e agrega inúmeras drogas. Nesse sentido, manter a atenção ao preparar e administrar corretamente os medicamentos é fundamental em todo o período de assistência ao recém-nascido. Portanto, faz-se necessário que os enfermeiros tenham o entendimento acerca do conceito do erro com medicação, para que possa identificá-lo, bem como os fatores contribuintes para sua ocorrência. Diante do exposto, esta pesquisa teve como objetivos: analisar o entendimento dos enfermeiros neonatologistas sobre o conceito do erro de medicação em uma unidade de terapia intensiva neonatal; conhecer na visão destes enfermeiros quais os fatores contribuintes para a ocorrência desse erro e discutir a partir desta visão como estes fatores podem afetar a segurança do neonato. Metodologia: trata-se de uma pesquisa qualitativa, do tipo descritiva. O cenário do estudo foi uma unidade de terapia intensiva neonatal de um hospital universitário, situado no município do Rio de Janeiro. Os sujeitos foram 14 enfermeiros entre plantonistas e residentes que atuavam no manejo da terapia medicamentosa. Para a coleta dos dados utilizou-se a entrevista semiestruturada, que foram analisadas através da análise de conteúdo de Bardin, emergindo 04 categorias: Diversos conceitos sobre erros de medicação; Fatores humanos contribuintes ao erro de medicação; Fatores ambientais contribuintes ao erro de medicação e Conhecendo como os fatores contribuintes ao erro podem afetar a segurança do paciente. Para as enfermeiras o erro de medicação significa errar um dos cinco certos na administração de medicamentos (paciente, dose, via, horário e medicamento certo), e este pode acontecer em alguma parte do sistema de medicação. Neste sentido, elas entendem que uma pessoa não pode ser considerada a única responsável pela ocorrência de um erro medicamentoso...
The management of drug therapy in a neonatal intensive care unit is complex and combines innumerous drugs. In this way, paying attention in the correct preparation and administration of drugs is fundamental in the whole period of assistance to the newborn infants. Therefore, is necessary that the nurses have the understanding of the concept of medication error, in order to be able to identify it as well as the contributing factors for its occurrence. In the presence of what was told, this research had as its aims: to analyze the understanding of the neonatal nurses of the concept of medication error in a neonatal intensive care unit; to apprehend from the perspective of these nurses, which contributing factor could affect the safety of the neonate. Methodology: it is a qualitative research with a descriptive design. The study setting was a neonatal intensive care unit from a university hospital in the city of Rio de Janeiro. The participants were 14 nurses, attending and resident physicians, which operate in the management of drug therapy. For the data collection a semi-structured interview was used, and then analyzed through the content analysis of Bardin, from what 04 categories emerged: different concepts of medication error; human contributing factors to the medication error; environmental contributing factors to the medication error; and understanding how the contributing factors to the medication error can affect the safety of the patient. For the nurses the medication error means making a mistake in one of the five rights in the medication administration (the right patient, the right dose, the right route, the right time, and the right drug), and this can happen in any part of the medication-use process. Thus, they understand that one person cannot be considered the only responsible for the occurrence of a medication error...

In the field of adult psychiatry in German-speaking countries, little attention is as yet paid to the psychic defects that a fetus can sustain as a result of prenatal exposure to alcohol. Although children of alcohol-dependent mothers do present to psychiatric institutions as adults with manifold symptoms, e. g., attention deficit disorders, affective disorders or intellectual disability, fetal alcohol spectrum disorders are rarely diagnosed as an underlying cause. Appropriate therapy guidelines do not exist. Current review papers within the German-speaking countries usually stem from paediatric and adolescent psychiatry or medicine. Based on a selected review of the literature, the following paper addresses and discusses the disease entity of fetal alcohol spectrum disorders and fetal alcohol syndrome and their significance for adult psychiatry and also identifies open questions and research requirements, e. g., the development of diagnostic instruments or the establishment of diagnostic categories.

The identification of mechanisms and outcomes for neurobehavioral teratogenesis is critical to our ability to develop therapies to ameliorate or reverse the deleterious effects of exposure to developmental neurotoxicants. We established mechanistically-based complementary models for the study of cholinergic systems in the mouse and the chick, using both environmental neurotoxicants (chlorpyrifos, perfluoroalkyls) and drugs of abuse (heroin, nicotine, PCP). Behavioral evaluations were made using the Morris maze in the mouse, evaluating visuospatial memory related to hippocampal cholinergic systems, and imprinting in the chick, examining behavior dependent on cholinergic innervation of the IMHV. In both models we demonstrated the dependence of neurobehavioral deficits on impairment of cholinergic receptor-induced expression, and translocation of specific PKC isoforms. Understanding this mechanism, we were able to reverse both the synaptic and behavioral deficits with administration of neural progenitors. We discuss the prospects for clinical application of neural progenitor therapy, emphasizing protocols for reducing or eliminating immunologic rejection, as well as minimizing invasiveness of procedures through development of intravenous administration protocols.

BACKGROUND: Perception of risk may impact a woman's decision to take a needed drug during pregnancy. There is a paucity of research on this topic in the literature. OBJECTIVES: (1) To evaluate the perception of risk of 17 commonly used drugs and other substances by pregnant women. (2) To investigate which sources of information regarding exposures during pregnancy were most commonly used by women. METHODS: A questionnaire was developed through the University of Oslo's website for Internet surveys and posted on four Web pages used by pregnant women and mothers, from mid-September 2008 through October 2008. The inclusion criteria included women who were (1) pregnant or 2) a mother of a child less than 5 years old. RESULTS: A total of 1,793 eligible women completed the questionnaire. Most women overestimated the teratogenic risk associated with all the drugs during pregnancy. Characteristics of the women that were associated with a high perception of risk were primiparity, higher age, higher education, and choosing not to use a drug during pregnancy. More than 80% of the women had used drugs during pregnancy, mostly paracetamol, penicillins and reflux medications. The physician, the product information leaflet and the pharmacist were the three most frequently used sources of information. CONCLUSION: Women overestimate the risk of drug use and other exposures during pregnancy. Therefore, it is important for health care providers to use evidence-based information, to reduce unnecessary anxiety, and to ensure safe and appropriate treatment during pregnancy.

BACKGROUND: Previous research has demonstrated that heavy prenatal alcohol exposure affects the size and shape of the corpus callosum (CC) and compromises interhemispheric transfer of information. The aim of this study was to confirm the previous reports of poorer performance on a finger localization test (FLT) of interhemispheric transfer in a cohort of heavily exposed children and to extend these findings to a cohort of moderately exposed young adults. METHODS: In Study 1, the FLT was administered to 40 heavily exposed and 23 nonexposed children from the Cape Coloured community of Cape Town, South Africa, who were evaluated for fetal alcohol syndrome (FAS) dysmorphology and growth. Anatomical images of the CC were obtained using structural MRI on a subset of these children. In Study 2, the FLT was administered to a cohort of 85 moderate-to-heavily exposed young adults participating in a 19-year follow-up assessment of the Detroit Prenatal Alcohol Exposure cohort, whose alcohol exposure had been ascertained prospectively during gestation. RESULTS: In Study 1, children with FAS showed more transfer-related errors than controls after adjustment for confounding, and increased transfer-related errors were associated with volume reductions in the isthmus and splenium of the CC. In Study 2, transfer-related errors were associated with quantity of alcohol consumed per occasion during pregnancy. More errors were made if the mother reported binge drinking (> or =5 standard drinks) during pregnancy than if she drank regularly (M > or = 1 drink/day) without binge drinking. CONCLUSIONS: These findings confirm a previous report of impaired interhemispheric transfer of tactile information in children heavily exposed to alcohol in utero and extend these findings to show that these deficits are also seen in more moderately exposed individuals, particularly those exposed to binge-like pregnancy drinking.

OBJECTIVE: Although the classic features of fetal alcohol syndrome have been recognized since 1968, research on alcohol teratogenesis has only recently demonstrated that the brain is the organ in the body most vulnerable to the effects of prenatal alcohol exposure. In this present article, we reviewed the literature focusing mainly on behavioral disturbances related to prenatal ethanol exposure. SOURCES: We performed a PubMed search on the literature published between 1968 and 2006 using the terms ethanol, pregnancy and behavior. We limited our search to studies on humans. SUMMARY OF THE FINDINGS: The data presented in this review suggested that youths with fetal alcohol spectrum disorder are at risk of disruptive social behavior, among other neurobehavioral abnormalities. CONCLUSIONS: Although it is still impossible to completely separate brain teratogenesis secondary to alcohol exposure from environmental postnatal influences as the definite cause for these outcomes, the pediatrician should be encouraged to early diagnose children affected by fetal alcohol syndrome and fetal alcohol spectrum disorder. This provides proper management and care and avoids long-term consequences on their behavior, besides ensuring better and productive school and social adaptation.

OBJETIVO: Ainda que as características clássicas da síndrome fetal alcoólica tenham sido descritas desde 1968, a pesquisa sobre a teratogênese do álcool apenas recentemente demonstrou que o cérebro é o órgão do corpo mais vulnerável aos efeitos da exposição pré-natal ao álcool. No presente artigo, fazemos uma revisão da literatura focalizando principalmente os distúrbios comportamentais relacionados à exposição pré-natal ao álcool. FONTES DOS DADOS: Foi realizada uma pesquisa com base no PubMed sobre a literatura publicada entre 1968 e 2006, com as palavras-chave etanol, gestação e comportamento. Foram estabelecidos limites a estudos em humanos. SÍNTESE DOS DADOS: Os dados apresentados nesta revisão sugerem que jovens com efeitos do espectro do álcool fetal estão sob risco maior de terem comportamento social disruptivo, entre outros problemas neurocomportamentais. CONCLUSÕES: Ainda que seja impossível separar completamente a teratogênese sobre o cérebro decorrente da exposição ao álcool de influências ambientais pós-natais como a causa definitiva desses resultados, o pediatra deve ser estimulado ao diagnóstico precoce de crianças afetadas pela síndrome fetal alcoólica e efeitos do espectro do álcool fetal. Isso permite iniciar o manejo e cuidados apropriados para evitar as conseqüências em longo prazo no comportamento e assegurar uma adaptação social e escolar melhor e mais produtiva.

The majority of children of mothers with epilepsy are normal, but they are at increased risk for developmental delay. Antiepileptic drugs (AEDs) appear to play a role. Our current knowledge is reviewed, including research design issues and recommendations for future research. In animals, exposure of the immature brain to some AEDs can produce widespread neuronal apoptosis and behavioral deficits. The risks of AEDs in humans are less clear, but recent studies raise concerns, especially for valproate. There is a critical need for well-designed systematic research to improve our understanding of AED effects on the fetal brain.
