More than 7 million individuals have been conceived by Assisted Reproductive Technologies (ART) and there is clear evidence that ART is associated with a range of adverse early life outcomes, including rare imprinting disorders. The periconception period and early embryogenesis are associated with widespread epigenetic remodeling, which can be influenced by ART, with effects on the developmental trajectory in utero, and potentially on health throughout life. Here we profile genome-wide DNA methylation in blood collected in the newborn period and in adulthood (age 22–35 years) from a unique longitudinal cohort of ART-conceived individuals, previously shown to have no differences in health outcomes in early adulthood compared with non-ART-conceived individuals. We show evidence for specific ART-associated variation in methylation around birth, most of which occurred independently of embryo culturing. Importantly, ART-associated epigenetic variation at birth largely resolves by adulthood with no direct evidence that it impacts on development and health.

This study aimed to examine the choice pregnant women make about the amount of fetal genetic information they want from chromosome microarray. Women having invasive prenatal testing in the absence of fetal structural abnormality were recruited in Victoria, Australia. A decision aid for women described 'targeted' analysis as reporting only copy number variants implicated in a highly penetrant and well-described phenotype and 'extended' as additionally reporting variants of uncertain or unknown significance. Participant's choice and demographics were collected by survey before chorionic villus sampling or amniocentesis; psychological data were also collected then and again about 10 days after receiving results. High-resolution single-nucleotide polymorphism array analysis was performed, and a clinical review committee assessed variants for reporting before returning results to participants. Sixty-six participants (59.5%) chose extended analysis and 45 (40.5%) targeted. Choosing extended information was associated with (1) indication for prenatal diagnosis: maternal age alone (adjusted odds ratio (adjOR) 9.6, 95% confidence interval (CI): 1.4-66.0, p= 0.02), or 'other' indication (adjOR 7.1, 95% CI: 1.5-33.1, p= 0.01)); (2) >12 months to conceive (adjOR 4.1, 95% CI: 1.0-17.7, p= 0.05); and (3) Asian background (adjOR 4.67, 95% CI: 1.0-21.0, p= 0.04). No adverse psychological impact occurred in either group. We conclude that offering pregnant women different levels of fetal genetic analysis is warranted, alongside decision support.

This qualitative study explored the psychosocial concerns of children born with congenital hand and upper limb differences (CHULDs) from the point of view of these children and their parents. Qualitative, in-depth, semi-structured interviews were conducted face-to-face with eight parent–child dyads. Open format questions allowed spontaneous emergence of relevant themes, followed by guided questioning. Thematic analysis of audio-recorded and transcribed interviews found that children as young as 5 years old had unique and meaningful opinions about their CHULD, of which parents were sometimes unaware. Children reported that unsolicited questions from peers caused significant stress, and this increased around the time of surgery. All children used planned responses to peers as an effective coping mechanism. Children also identified positive aspects of their difference, including an increased sense of determination and an appreciation for being unique. Strategies that may improve psychosocial outcomes for children with CHULDs are discussed. Level of evidence: IV
