The association between SARS-CoV-2 infection and preterm delivery: a prospective study with a multivariable analysis.

Background: To determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, the cause of COVID-19 disease) exposure in pregnancy, compared to non-exposure, is associated with infection-related obstetric morbidity.

Methods: We conducted a multicentre prospective study in pregnancy based on a universal antenatal screening program for SARS-CoV-2 infection. Throughout Spain 45 hospitals tested all women at admission on delivery ward using polymerase-chain-reaction (PCR) for COVID-19 since late March 2020.

Obstetric Outcomes of SARS-CoV-2 Infection in Asymptomatic Pregnant Women.

Around two percent of asymptomatic women in labor test positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Spain. Families and care providers face childbirth with uncertainty. We determined if SARS-CoV-2 infection at delivery among asymptomatic mothers had different obstetric outcomes compared to negative patients.

[Ultrasonography as a method to determine the correct implantation of intratubaric devices].

Background: Essure procedure consists in the placement of two coils in the intramural segment of Fallopian tubes by hysteroscopic causing a fibrosis reaction that unleashes a physiological obstruction. Hysterosalpingography, until today, is the gold standard checking the success of this method of sterilization.

Objective: Determining if a scan at three months postimplantation is sufficient to confirm the correct positioning of the device.
