Relevance of N6-methyladenosine regulators for transcriptome: Implications for development and the cardiovascular system.

J Mol Cell Cardiol 2021 May 12. Epub 2021 May 12.

National Heart and Lung Institute, Imperial College London, Hammersmith Campus, Du Cane Road, London W12 0NN, UK. Electronic address:

N6-methyladenosine (m6A) is the most abundant and well-studied internal modification of messenger RNAs among the various RNA modifications in eukaryotic cells. Moreover, it is increasingly recognized to regulate non-coding RNAs. The dynamic and reversible nature of m6A is ensured by the precise and coordinated activity of specific proteins able to insert ("write"), bind ("read") or remove ("erase") the m6A modification from coding and non-coding RNA molecules.

An ensemble of neural networks provides expert-level prenatal detection of complex congenital heart disease.

Nat Med 2021 May 14;27(5):882-891. Epub 2021 May 14.

Division of Cardiology, Department of Pediatrics, University of California, San Francisco,, San Francisco, CA, USA.

Congenital heart disease (CHD) is the most common birth defect. Fetal screening ultrasound provides five views of the heart that together can detect 90% of complex CHD, but in practice, sensitivity is as low as 30%. Here, using 107,823 images from 1,326 retrospective echocardiograms and screening ultrasounds from 18- to 24-week fetuses, we trained an ensemble of neural networks to identify recommended cardiac views and distinguish between normal hearts and complex CHD.

Two factors affecting the success rate of the second non-invasive prenatal screening after initial no-call result: experience from a single tertiary center in China.

Chin Med J (Engl) 2021 May 13. Epub 2021 May 13.

Department of Prenatal Diagnosis, Women's Hospital of Nanjing Medical University, Nanjing Maternity and Child Health Care Hospital, Nanjing, Jiangsu 210004, China Center of Genetic Medicine, Women's Hospital of Nanjing Medical University, Nanjing Maternity and Child Health Care Hospital, Nanjing, Jiangsu 210004, China.

Background: One inevitable shortcoming of non-invasive prenatal screening (NIPS)/cell-free DNA (cfDNA) sequencing is the uninterpretable ("no-call") result, which is mainly caused by an insufficient fetal fraction. This study was performed to investigate the factors associated with a successful second NIPS in these cases and determine the optimal management for women with initial no-call results.

Methods: We retrospectively analyzed the data of women who underwent NIPS with initial no-call results due to an insufficient fetal fraction from 2017 to 2019 in our center. Read More

Perinatal DEHP exposure induces sex- and tissue-specific DNA methylation changes in both juvenile and adult mice.

Environ Epigenet 2021 10;7(1):dvab004. Epub 2021 May 10.

Department of Computational Medicine and Bioinformatics, University of Michigan, 500 S State St., Ann Arbor, MI 48109, USA.

Di(2-ethylhexyl) phthalate (DEHP) is a type of phthalate plasticizer found in a variety of consumer products and poses a public health concern due to its metabolic and endocrine disruption activities. Dysregulation of epigenetic modifications, including DNA methylation, has been shown to be an important mechanism for the pathogenic effects of prenatal exposures, including phthalates. In this study, we used an established mouse model to study the effect of perinatal DEHP exposure on the DNA methylation profile in liver (a primary target tissue of DEHP) and blood (a common surrogate tissue) of both juvenile and adult mice.

The path toward ectogenesis: looking beyond the technical challenges.

Authors:
Seppe Segers

BMC Med Ethics 2021 May 13;22(1):59. Epub 2021 May 13.

Department of Philosophy and Moral Sciences, Bioethics Institute Ghent, Ghent University, Blandijnberg 2, 9000, Ghent, Belgium.

Background: Breakthroughs in animal studies make the topic of human application of ectogenesis for medical and non-medical purposes more relevant than ever before. While current data do not yet demonstrate a reasonable expectation of clinical benefit soon, several groups are investigating the feasibility of artificial uteri for extracorporeal human gestation.

Main Text: This paper offers the first comprehensive and up to date discussion of the most important pros and cons of human ectogenesis in light of clinical application, along with an examination of crucial ethical (and legal) issues that continued research into, and the clinical translation of, ectogenesis gives rise to.

Pregnancy outcomes in women with booking HbA1c ≤ 40 mmol/mol compared with 41-49 mmol/mol in South Auckland, New Zealand.

Aust N Z J Obstet Gynaecol 2021 May 13. Epub 2021 May 13.

Counties Manukau Health, Auckland, New Zealand.

Aims: There are few data on pregnancy outcomes in women with pre-diabetes (HbA1c 41-49 mmol/mmol) at pregnancy booking. We aimed to (i) identify the proportion of women in Counties Manukau Health (CMH), South Auckland, New Zealand (NZ), with pre-diabetes at booking and (ii) compare outcomes between women with normal HbA1c and pre-diabetes.

Materials And Methods: Using data from a multi-ethnic population of 10,869 singleton pregnancies, booked at <20 weeks from January 2017 to December 2018 in CMH, we compared outcomes between those with normal HbA1c (≤40 mmol/mol) and those with pre-diabetes (HbA1c 41-49 mmol/mol). Read More

Confined placental mosaicism and the association with pregnancy outcome and fetal growth: a review of the literature.

Hum Reprod Update 2021 May 13. Epub 2021 May 13.

Department of Clinical Genetics, Erasmus MC, University Medical Center, Rotterdam 3015CN, The Netherlands.

Background: Chromosomal mosaicism can be detected in different stages of early life: in cleavage stage embryos, in blastocysts and biopsied cells from blastocysts during preimplantation genetic testing for aneuploidies (PGT-A) and later during prenatal testing, as well as after birth in cord blood. Mosaicism at all different stages can be associated with adverse pregnancy outcomes. There is an onward discussion about whether blastocysts diagnosed as chromosomally mosaic by PGT-A should be considered safe for transfer. Read More

Maternal smoking and smokeless tobacco use during pregnancy and offspring development: sibling analysis in an intergenerational Swedish cohort.

Int J Epidemiol 2021 May 13. Epub 2021 May 13.

Centre for Academic Mental Health, Population Health Sciences, Bristol Medical School, University of Bristol, Bristol, UK.

Background: The association between maternal smoking in pregnancy and offspring intellectual disability (ID) is less well understood than that of smoking and fetal growth restriction. As fetal growth and cognitive development may share similar confounding structures, comparison of the two associations may improve understanding of the causal nature of the association with ID. Furthermore, comparisons of smoking with smokeless tobacco use may aid identification of mechanisms of action. Read More

Integrative methylome-transcriptome analysis unravels cancer cell vulnerabilities in infant MLL-rearranged B-cell acute lymphoblastic leukemia.

J Clin Invest 2021 May 13. Epub 2021 May 13.

Josep Carreras Leukemia Research Institute-Campus Clinic, University of Barcelona, Barcelona, Spain.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common childhood cancer. As predicated by its prenatal origin, infant B-ALL (iB-ALL) shows an exceptionally silent DNA mutational landscape, suggesting that alternative epigenetic mechanisms may substantially contribute to its leukemogenesis. Here, we have integrated genome-wide DNA methylome and transcriptome data from 69 patients with de novo MLL-rearranged (MLLr) and non-MLLr iB-ALL leukemias uniformly treated according to Interfant-99/06 protocol.

Measurement of neurodevelopmental effects of prenatal alcohol exposure in Ukrainian preschool children.

Child Neuropsychol 2021 May 13:1-16. Epub 2021 May 13.

Collaborative Initiative for Fetal Alcohol Spectrum Disorders.

Effects of prenatal alcohol exposure (PAE) are rarely measured in preschool children due to relative insensitivity of assessment methods at this age. To examine the potential of a nonverbal battery in early identification of cognitive problems in alcohol-exposed children, 291 prospectively identified Ukrainian children were evaluated using a test battery focusing on early executive functioning (EF) and visuospatial skills, areas of cognitive development particularly sensitive to PAE in older children. Tests included the Differential Ability Scales, 2 Edition (DAS-2) and several NEPSY/NEPSY-II subtests, standardized in the United States. Read More
