\begin{abstract}
Hi Reddit, My name is Sarka Lisonkova and I am an Assistant Professor at
the University of British Columbia, Department of Obstetrics and
Gynaecology. My research focuses on risk factors and determinants of
severe maternal morbidity. I recently published a study titled `Maternal
age and severe maternal morbidity: a population-based retrospective
cohort study' in PLOS Medicine. This study shows that older mothers --
aged 40 years or more -- have increasingly higher rates of potentially
life-threatening conditions including acute cardiac events, shock, acute
renal failure, amniotic fluid embolism, and serious complications of
obstetric interventions. Even though these serious complications are
rare, our results provide important information for counseling to women
who contemplate delaying childbirth until their forties. I will be
answering your questions at 1pm ET. Ask me Anything! Don't forget to
follow me on Twitter @sarkalis.%
