Neonatal mortality by gestational age in days in infants born at term: A cohort study in Sao Paulo city, Brazil.

Birth at term comprises a period with heterogeneous neonatal outcomes that tend to be worse for infants born earlier. However, few studies have analyzed this period, in which each day can make a difference. Therefore, we aim to assess neonatal mortality (NM) according to gestational age (GA) at birth measured in days in term liveborn infants born in 2012-2017 in São Paulo, the largest city in Latin America.

Potential pregnancy days lost: an innovative measure of gestational age.

In Brazil, the excess of interventions that anticipate childbirth, such as cesarean sections and labor inductions, has resulted in the shortening of pregnancy, with negative consequences on maternal-infant outcomes. This commentary presents a novel way to measure gestational age: the continuous variable "Potential pregnancy days lost." Using data from the Live Birth Information System (SINASC), we counted the missing days between the period until childbirth and the average duration of pregnancy (280 days), or the lost weeks.

Using the Maternity Safety Thermometer to estimate harm-free care in Southeast Brazil: A hospital-based cohort.

Background: High rates of unnecessary cesareans and interventions in vaginal births contribute to stagnant maternal and neonatal mortality rates in Brazil. We used the Maternity Safety Thermometer (MST) to assess the prevalence of harm during maternity care.

Methods: This secondary analysis of the "Birth in Brazil" survey included a representative sample of 10 155 women who gave birth in public and private hospitals in southeastern Brazil.
