Blood Pressure Changes in Adolescents with Preeclampsia: A Multicentre, Case-Control Study in Latin American Hospitals.

Objective: To determine the minimum blood pressure increases that would confirm or exclude, with the greatest predictive values, hypertensive disorders of pregnancy (HDP) in pregnant adolescents after 24 weeks gestation.

Methods: We conducted a case-control study of pregnant women aged ≤19 years with and without HDP. Using systolic and diastolic blood pressure increases, a predictive analysis was performed, and the area under the curve was calculated.

Expectant management of severe preeclampsia remote from term: the MEXPRE Latin Study, a randomized, multicenter clinical trial.

Objective: The objective of the study was to determine whether expectant management of severe preeclampsia prior to 34 weeks of gestation results in improved neonatal outcome in countries with limited resources.

Study Design: This was a randomized clinical trial performed in 8 tertiary hospitals in Latin America. Criteria of randomization included gestational age between 28 and 33 weeks' gestation and the presence of severe hypertensive disorders.
