Population implications of cessation of IVF during the COVID-19 pandemic (2020)
Journal Article
Smith, A., Gromski, P., Al Rashid, K., Tilling, K., Lawlor, D., & Nelson, S. M. (in press). Population implications of cessation of IVF during the COVID-19 pandemic. Reproductive BioMedicine Online, https://doi.org/10.1016/j.rbmo.2020.07.002

Research Question Discontinuation of in vitro fertilisation (IVF) cycles has been part of the radical transformation of healthcare provision to enable reallocation of staff and resources to deal with the COVID-19 pandemic. We sought to estimate the... Read More about Population implications of cessation of IVF during the COVID-19 pandemic.

The mental health effects of pet death during childhood: Is it better to have loved and lost than never to have loved at all? (2020)
Journal Article
Crawford, K., Zhu, Y., Davis, K., Ernst, S., Jacobsson, K., Nishimi, K., …Dunn, E. (in press). The mental health effects of pet death during childhood: Is it better to have loved and lost than never to have loved at all?. European Child and Adolescent Psychiatry,

Background: Pet ownership is common. Growing evidence suggests children form deep emotional attachments to their pets. Yet, little is known about children’s emotional reactions to a pet’s death. Aims: To describe the relationship between experie... Read More about The mental health effects of pet death during childhood: Is it better to have loved and lost than never to have loved at all?.

Live birth rates and perinatal outcomes when all embryos are frozen compared with conventional fresh and frozen embryo transfer: a cohort study of 337,148 in vitro fertilisation cycles (2019)
Journal Article
Smith, A., Tilling, K., Lawlor, D., & Nelson, S. (2019). Live birth rates and perinatal outcomes when all embryos are frozen compared with conventional fresh and frozen embryo transfer: a cohort study of 337,148 in vitro fertilisation cycles. BMC Medicine, 17(1), https://doi.org/10.1186/s12916-019-1429-z

BACKGROUND: It is not known whether segmentation of an in vitro fertilisation (IVF) cycle, with freezing of all embryos prior to transfer, increases the chance of a live birth after all embryos are transferred. METHODS: In a prospective study of UK H...

Adversity exposure during sensitive periods predicts accelerated epigenetic aging in children (2019)
Journal Article
Marini, S., Davis, K. A., Soare, T. W., Zhu, Y., Suderman, M. J., Simpkin, A. J., …Dunn, E. C. (2020). Adversity exposure during sensitive periods predicts accelerated epigenetic aging in children. Psychoneuroendocrinology, 113, https://doi.org/10.1016/j.psyneuen.2019.104484

Objectives: Exposure to adversity has been linked to accelerated biological aging, which in turn has been shown to predict numerous physical and mental health problems. In recent years, measures of DNA methylation-based epigenetic age––known as “epig... Read More about Adversity exposure during sensitive periods predicts accelerated epigenetic aging in children.

Sensitive periods for the effect of childhood adversity on DNA methylation: Results from a prospective, longitudinal study (2019)
Journal Article
Dunn, E. C., Soare, T. W., Zhu, Y., Simpkin, A. J., Suderman, M. J., Klengel, T., …Relton, C. L. (2019).

Biological Psychiatry, 85(10), 838-849. https://doi.org/10.1016/j.biopsych.2018.12.023

Background: Exposure to "early life" adversity is known to predict DNA methylation (DNAm) patterns that may be related to psychiatric risk. However, few studies have investigated whether adversity has time-dependent effects based on the age at exposu...
