Overview

Keith F. Walker was affiliated with the University of Adelaide in Australia and contributed extensively to research in the field of medicine with a focus on obstetrics and gynecology. Their scholarly work spanned several related subfields including public health, environmental and occupational health, pediatrics, perinatology and child health, epidemiology, and surgery.

Their research topics frequently addressed issues related to maternal and perinatal health interventions, the impact of COVID-19 on reproduction, maternal and fetal healthcare, neonatal and maternal infections, streptococcal infections and treatments, pregnancy and preeclampsia studies, and pelvic floor disorders treatments.

Several recent papers illustrate their research contributions:

  • Maternal transmission of SARS-COV-2 to the neonate, and possible routes for such transmission: a systematic review and critical analysis (2020) published in BJOG An International Journal of Obstetrics & Gynaecology
  • SARS-CoV-2 positivity in offspring and timing of mother-to-child transmission: living systematic review and meta-analysis (2022) published in BMJ
  • Pharmacological interventions for treating intrahepatic cholestasis of pregnancy (2020) published in Cochrane Database of Systematic Reviews
  • Haemostatic and thrombo-embolic complications in pregnant women with COVID-19: a systematic review and critical analysis (2021) published in BMC Pregnancy and Childbirth
  • Impacted fetal head during second stage Caesarean birth: A prospective observational study (2022) published in European Journal of Obstetrics & Gynecology and Reproductive Biology

Walker's frequent coauthors included Jim Thornton, Eleanor Mitchell, Keelin O'Donoghue, Jon Dorling, and Nia Jones.

Their work appeared regularly in several publication venues, notably:

  • European Journal of Obstetrics & Gynecology and Reproductive Biology
  • Obstetrics Gynaecology & Reproductive Medicine
  • BJOG An International Journal of Obstetrics & Gynaecology
  • BMC Pregnancy and Childbirth
  • The Journal of Sexual Medicine

During their career, Keith F. Walker produced a significant number of publications addressing medical challenges around reproduction, maternal and neonatal health, and infectious diseases in the context of pregnancy. Their systematic reviews and meta-analyses brought together clinical data and critical analyses in these areas, contributing to a deeper understanding of health risks and treatment approaches.
