Laura A. Magee,Peter von Dadelszen,Evelyne Rey,Sue Ross,Elizabeth Asztalos,Kellie E. Murphy,Jennifer Menzies,J. Johanna Sanchez,Joel Singer,Amiram Gafni,Andrée Gruslin,Michael Helewa,Eileen K. Hutton,Shoo K. Lee,Terry Lee,Alexander G. Logan,Wessel Ganzevoort,Ross Welch,Jim G Thornton,Jean Marie Moutquin +19 more
TL;DR: It is found that less-tight control was associated with a significantly higher frequency of severe maternal hypertension, although no significant between-group differences in the risk of pregnancy loss, high-level neonatal care, or overall maternal complications are found.

Jon Barrett,Mary E. Hannah,Eileen K. Hutton,Andrew R. Willan,Alexander C. Allen,B. Anthony Armson,Amiram Gafni,Dalah Mason,Arne Ohlsson,Sue Ross,J. Johanna Sanchez,Elizabeth Asztalos +11 more
TL;DR: In twin pregnancy between 32 weeks 0 days and 38 weeks 6 days of gestation, planned cesarean delivery did not significantly decrease or increase the risk of fetal or neonatal death or serious neonatal morbidity, as compared with planned vaginal delivery.

The CHIPS Randomized Controlled Trial (Control of Hypertension in Pregnancy Study): Is Severe Hypertension Just an Elevated Blood Pressure?
Laura A. Magee,Peter von Dadelszen,Joel Singer,Terry Lee,Evelyne Rey,Sue Ross,Elizabeth Asztalos,Kellie E. Murphy,Jennifer Menzies,J. Johanna Sanchez,Amiram Gafni,Michael Helewa,Eileen K. Hutton,Gideon Koren,Shoo K. Lee,Alexander G. Logan,Wessel Ganzevoort,Ross Welch,Jim G Thornton,Jean-Marie Moutquin +19 more
TL;DR: In this article, mixed effects logistic regression was used to compare the following outcomes according to occurrence of severe hypertension, adjusting for allocated group and the influence of baseline factors: CHIPS primary (perinatal loss or high-level neonatal care for >48 hours) and secondary outcomes (serious maternal complications), birth weight 9 /L, elevated liver enzymes with symptoms, maternal length of stay ≥10 days, and maternal readmission before 6 weeks postpartum.

Multiple courses of antenatal corticosteroids for preterm birth study: outcomes in children at 5 years of age (MACS-5).
Elizabeth Asztalos,Kellie E. Murphy,Andrew R. Willan,Stephen G. Matthews,Arne Ohlsson,Saroj Saigal,B. Anthony Armson,Edmond Kelly,Marie-France Delisle,Amiram Gafni,Shoo K. Lee,Renee Sananes,Joanne Rovet,Patricia Guselle,Kofi Amankwah,Mariam Saleem,J. Johanna Sanchez +16 more
TL;DR: It remains the opinion that multiple courses, compared with a single course, of antenatal corticosteroid therapy did not increase or decrease the risk of death or disability at 5 years of age, and it remains a lack of strong conclusive evidence of short-term or long-term benefits.
