Birth outcomes in women exposed to diagnostic radiology procedures during first trimester of pregnancy: a prospective cohort study.

Clin Toxicol (Phila) 2021 May 28:1-9. Epub 2021 May 28.

Toxicology Unit and Poison Control Centre, Teratology Information Service, Careggi University Hospital, Florence, Italy.

Introduction: Exposure of the embryo or fetus to ionizing radiations is a potential danger since it may induce clinically relevant fetal and/or neonatal damages. The aim of the present study was to examine fetal and neonatal outcomes after maternal exposure to radio-diagnostic procedures during first trimester of pregnancy, and to evaluate whether these effects might be related to the fetal absorbed dose of ionizing radiations.

Methods: A 10-year prospective cohort study was performed on 1979 pregnant women who underwent a radio-diagnostic procedure within the first trimester of pregnancy. Read More

Fatty acid ethyl esters in meconium and substance use in adolescence.

Neurotoxicol Teratol 2021 Jan-Feb;83:106946. Epub 2020 Dec 23.

Department of Pediatrics, Case Western Reserve University, United States.

Prenatal alcohol exposure (PAE) continues to be a serious public health problem, yet no reliable clinical tools are available for assessing levels of drinking during pregnancy. Fatty acid ethyl esters (FAEEs), the nonoxidative metabolites of ethanol measured in meconium, are potential biomarkers to quantify the level of PAE. The association between the concentrations of FAEEs from meconium and adolescent substance use and related problems was examined in a prospective birth-cohort of adolescents exposed to alcohol and drugs in utero.

Combined vapor exposure to THC and alcohol in pregnant rats: Maternal outcomes and pharmacokinetic effects.

Neurotoxicol Teratol 2020 Nov - Dec;82:106930. Epub 2020 Oct 18.

Center for Behavioral Teratology, Dept. of Psychology, San Diego State University, USA. Electronic address:

Cannabis is the most frequently used illicit drug among pregnant women, yet the potential consequences of prenatal cannabis exposure on development are not well understood. Electronic cigarettes have become an increasingly popular route of administration among pregnant women, in part to user's perception that e-cigarettes are a safer route for consuming cannabis products. Importantly, half of pregnant women who consume cannabis also report consuming alcohol, but research investigating co-consumption of these drugs is limited, particularly with current routes of administration.

Mult Scler Relat Disord 2020 Aug 6;43:102146. Epub 2020 May 6.

University of Cambridge, Cambridge, United Kingdom. Electronic address:

Background: Relapsing-remitting multiple sclerosis (RRMS) is frequently diagnosed in women of reproductive age. Because the use of disease-modifying therapies (DMTs) early in the disease course is increasing, it is important to evaluate the safety of DMTs in pregnant women and their developing fetuses. Alemtuzumab, approved for the treatment of relapsing forms of MS, is administered as 2 courses of 12 mg/day on 5 consecutive days at baseline and on 3 consecutive days 12 months later. Read More

Maternal N-Acetyl Cysteine Intake Improved Glucose Tolerance in Obese Mice Offspring.

Int J Mol Sci 2020 Mar 13;21(6). Epub 2020 Mar 13.

Departments of Molecular Biology and Nutrition Sciences, Ariel University, Ariel 40700, Israel.

Exposure to certain environmental factors during the early stages of development was found to affect health in adulthood. Among other environmental factors, oxidative stress has been suggested to be involved in fetal programming, leading to elevated risk for metabolic disorders, including type 2 diabetes; however, the possibility that antioxidant consumption during early life may affect the development of diabetes has scarcely been studied. The aim of this study was to investigate the effects of -acetyl-l-cysteine (NAC) given during pregnancy and lactation on the susceptibility of offspring to develop glucose intolerance at adulthood.

Placental transporter-mediated drug interactions and offspring congenital anomalies.

Br J Clin Pharmacol 2020 05 20;86(5):868-879. Epub 2020 Jan 20.

Teratology Information, Department of Emergency Medicine Services, University of Helsinki and Helsinki University Hospital, Helsinki, Finland.

Aims: P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) are efflux transporters expressed in the placenta, limiting their substrates from reaching the foetus.

Carnosic Acid Reverses the Inhibition of ApoE4 on Cell Surface Level of ApoER2 and Reelin Signaling Pathway.

J Alzheimers Dis 2020 ;73(2):517-528

Department of Human Anatomy and Key Laboratory of Experimental Teratology, Ministry of Education, Shandong University School of Medicine, Jinan, Shandong, China.

The cell surface level of apolipoprotein E receptor 2 (ApoER2) increases by cyclic transport of ApoER2 and then activates Reelin signaling pathway to exert neuroprotective function in AD. ApoER2 ligand Apolipoprotein E4 (ApoE4) inhibits the recycling of ApoER2 to the cell surface rendering neurons unresponsive to Reelin. Carnosic acid (CA) is proven to possess neuroprotective and neurotrophic functions in Alzheimer's disease (AD) mouse model. Read More

Crack cocaine smoke on pregnant rats: Maternal evaluation and teratogenic effect.

Hum Exp Toxicol 2020 Apr 1;39(4):411-422. Epub 2019 Dec 1.

Institute of Environmental, Chemical and Pharmaceutical Sciences, Federal University of São Paulo (ICAQF-UNIFESP), Diadema, SP, Brazil.

This study aimed to evaluate maternal toxicity, teratogenic, and placental oxidative effects resulting from the exposure of rats to crack cocaine smoke during pregnancy. Pregnant rats were exposed either to the smoke of crack and ashes (Crack) or to the smoke of ashes alone, nonexposed or pair-fed with the Crack group. Crack group was exposed to the smoke resulting from the burning of 250 mg of crack for 10 min, twice a day, from 7 days prior to mating until cesarian on gestational day 20. Read More

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
