[Advanced maternal age as a risk factor for adverse maternal and perinatal outcomes].

Introduction: A progressive increase in the age of women at first pregnancy is observed, a situation that has been associated with a greater risk of adverse maternal and perinatal effects.

Objective: The aim of this study was to describe the characteristics and the maternal and perinatal outcomes of nulliparas of 40 years and older and compare them with those of nulliparas under 40.

Study Design: This was a retrospective cohort analysis of a database of pregnancy population who had attended their deliveries in a private university hospital.

Preterm premature rupture of membranes.

Preterm premature rupture of membranes occurs in around 3% of pregnancies, and several aspects related to its management are still controversial. The objective of this update is to provide a detailed review of strategies aimed at reducing morbidity and mortality associated with this maternal condition. We will discuss the available evidence regarding the maternal use of antibiotics, the use of corticosteroids according to gestational age, the use of magnesium sulphate for fetal neuroprotection, the use of tocolytic agents, and the best moment for and route of delivery.
