Estimating cumulative incidence functions in competing risks data with dependent left-truncation.

Stat Med 2020 02 1;39(4):481-493. Epub 2019 Dec 1.

Institute of Statistics, Ulm University, Ulm, Germany.

Both delayed study entry (left-truncation) and competing risks are common phenomena in observational time-to-event studies. For example, in studies conducted by Teratology Information Services (TIS) on adverse drug reactions during pregnancy, the natural time scale is gestational age, but women enter the study after time origin and upon contact with the service. Competing risks are present, because an elective termination may be precluded by a spontaneous abortion. Read More

Cross-sectional evaluation of prescription of valproate and other antiepileptic drugs to pregnant women.

Acta Neurol Belg 2019 Oct 28. Epub 2019 Oct 28.

Department of Pharmacology, Teratology Information Service, Kahramanmaras Sütçü Imam University, Faculty of Medicine, Avsar Kampusu, Onikisubat, Kahramanmaraş, Turkey.

Drug counseling is important in women with epilepsy since data about the effects of maternal antiepileptics on the developing fetus are limited. Although pregnant patients on the most teratogenic drugs are treated in accordance to the European Medicines Agency guidelines, a large amount of them may be exposed to the teratogenic medications unintentionally. We performed a tertiary center observational study about medications of pregnant women who were consulted to Teratology Information Service (TIS) unit for evidence-based teratogenic risk analysis.

Diagnosis and management of individuals with Fetal Valproate Spectrum Disorder; a consensus statement from the European Reference Network for Congenital Malformations and Intellectual Disability.

Orphanet J Rare Dis 2019 07 19;14(1):180. Epub 2019 Jul 19.

Clinical Genetics, Royal Devon and Exeter NHS Foundation Trust, Gladstone Rd, Exeter, UK.

Background: A pattern of major and minor congenital anomalies, facial dysmorphic features, and neurodevelopmental difficulties, including cognitive and social impairments has been reported in some children exposed to sodium valproate (VPA) during pregnancy. Recognition of the increased risks of in utero exposure to VPA for congenital malformations, and for the neurodevelopmental effects in particular, has taken many years but these are now acknowledged following the publication of the outcomes of several prospective studies and registries. As with other teratogens, exposure to VPA can have variable effects, ranging from a characteristic pattern of major malformations and significant intellectual disability to the other end of the continuum, characterised by facial dysmorphism which is often difficult to discern and a more moderate effect on neurodevelopment and general health.

Hippocampal transcriptome reveals novel targets of FASD pathogenesis.

Brain Behav 2019 07 29;9(7):e01334. Epub 2019 May 29.

Department of Veterinary Physiology and Pharmacology, College of Veterinary Medicine and Biomedical Sciences, Texas A&M University, College Station, Texas.

Introduction: Prenatal alcohol exposure can contribute to fetal alcohol spectrum disorders (FASD), characterized by a myriad of developmental impairments affecting behavior and cognition. Studies show that many of these functional impairments are associated with the hippocampus, a structure exhibiting exquisite vulnerability to developmental alcohol exposure and critically implicated in learning and memory; however, mechanisms underlying alcohol-induced hippocampal deficits remain poorly understood. By utilizing a high-throughput RNA-sequencing (RNA-seq) approach to address the neurobiological and molecular basis of prenatal alcohol-induced hippocampal functional deficits, we hypothesized that chronic binge prenatal alcohol exposure alters gene expression and global molecular pathways in the fetal hippocampus.

Ondansetron and teratogenicity in rats: Evidence for a mechanism mediated via embryonic hERG blockade.

Reprod Toxicol 2018 10 24;81:237-245. Epub 2018 Aug 24.

Discipline of Biomedical Sciences, Sydney Medical School, The Unvieristy of Sydney, Sydney, NSW 2006, Australia. Electronic address:

The potent hERG channel blocking drug ondansetron is used off-label for treatment of nausea and vomiting in early pregnancy. Some human epidemiological studies have associated ondansetron with fetal cardiovascular defects and orofacial clefts. This study investigated the effects of ondanestron on embryonic heart rhythm of gestational day (GD) 13 rat embryos in vitro and then integrated the results with published animal teratology, and animal and human pharmacokinetic studies to perform a risk evaluation.

Approach to evaluating pregnancy safety of anti-rheumatic medications in the OTIS MotherToBaby pregnancy studies: what have we learned?

Rheumatology (Oxford) 2018 07;57(suppl_5):v34-v39

Department of Pediatrics, Division of Dysmorphology and Teratology, University of California San Diego, La Jolla, CA, USA.

For the last 30 years, pregnancy exposure studies, with varying methodologies, have been the mainstay of post-marketing surveillance for new drugs likely to be used by women of reproductive age. While they provide valuable data to inform use during pregnancy, they have limitations that render them necessary but not sufficient in supplying timely information to patients and prescribers. The Organization of Teratology Information Specialists MotherToBaby Pregnancy Studies' collaborative research group operates to help fill this gap. Read More

Effects of dietary alpha-linolenic acid-enriched diacylglycerol oil on embryo/fetal development in rats.

Regul Toxicol Pharmacol 2018 Oct 27;98:108-114. Epub 2018 Jul 27.

R&D Safety Science Research, Kao Corporation, 2606, Akabane, Ichikai-machi, Haga-gun, Tochigi, 321-3497, Japan.

Recent studies suggest that diets supplemented with alpha-linolenic acid (ALA)-enriched diacylglycerol (DAG) oil provide potential health benefits in preventing or managing obesity. However, available safety information about reproductive and developmental toxicities of ALA-DAG oil is limited. This study was conducted to clarify the effect, if any, of ALA-DAG oil on embryo-fetal development, following maternal exposure during the critical period of major organogenesis. Read More

Blunted endogenous opioid release following an oral dexamphetamine challenge in abstinent alcohol-dependent individuals.

Mol Psychiatry 2018 Jun 25. Epub 2018 Jun 25.

Neuropsychopharmacology Unit, Centre for Psychiatry, Imperial College London, London, UK.

Addiction has been proposed as a 'reward deficient' state, which is compensated for with substance use. There is growing evidence of dysregulation in the opioid system, which plays a key role in reward, underpinning addiction. Low levels of endogenous opioids are implicated in vulnerability for developing alcohol dependence (AD) and high mu-opioid receptor (MOR) availability in early abstinence is associated with greater craving.

A shortened study design for embryo-fetal development studies in the minipig.

Reprod Toxicol 2018 09 22;80:35-43. Epub 2018 Jun 22.

Ellegaard Göttingen Minipigs, Dalmose, Denmark.

The minipig is accepted from scientific and regulatory perspectives for the safety evaluation of drug candidates on embryo-fetal development. The relative size and the duration of gestation (112-115 days) in the minipig is, however, considered a drawback compared with routine smaller species. We evaluated if study duration and cost could be optimized without impacting scientific validity by performing all terminal procedures around mid-gestation (60 days). Read More
