Placental growth factor at 24-28 weeks for aspirin discontinuation in pregnancies at high risk for preterm preeclampsia: Post hoc analysis of StopPRE trial.

Introduction: This study aims to evaluate the safety of discontinuing aspirin treatment at 24-28 weeks in women at high risk after first-trimester combined screening for preeclampsia (PE) and normal placental growth factor (PlGF) levels at 24-28 weeks of gestation.

Material And Methods: This is a post hoc analysis of the StopPRE trial, conducted at nine Spanish maternity hospitals from September 2019 to September 2021. In the StopPRE trial, all high-risk single pregnancies identified during first-trimester screening for PE were treated with 150 mg of daily aspirin.

Mid-trimester uterine artery Doppler for aspirin discontinuation in pregnancies at high risk for preterm pre-eclampsia: Post-hoc analysis of StopPRE trial.

Objective: To assess whether aspirin treatment can be discontinued in pregnancies with normal uterine artery pulsatility index (≤90th percentile) at 24-28 weeks.

Design: Post-hoc analysis of a clinical trial.

Setting: Nine maternity hospitals in Spain.

Aspirin Discontinuation at 24 to 28 Weeks' Gestation in Pregnancies at High Risk of Preterm Preeclampsia: A Randomized Clinical Trial.

Importance: Aspirin reduces the incidence of preterm preeclampsia by 62% in pregnant individuals at high risk of preeclampsia. However, aspirin might be associated with an increased risk of peripartum bleeding, which could be mitigated by discontinuing aspirin before term (37 weeks of gestation) and by an accurate selection of individuals at higher risk of preeclampsia in the first trimester of pregnancy.

Objective: To determine whether aspirin discontinuation in pregnant individuals with normal soluble fms-like tyrosine kinase-1 to placental growth factor (sFlt-1:PlGF) ratio between 24 and 28 weeks of gestation was noninferior to aspirin continuation to prevent preterm preeclampsia.

Pleuropulmonary blastoma as characteristic cause of pneumothorax.

Background: Pleuropulmonary blastoma (PPB) is the most common lung neoplasms in childhood. Usually presents as recurrent respiratory infections and in some cases as pneumothorax.

Case Report: We report the case of a 2-year-old patient that was diagnosed with PPB, that first manifested as recurrent pneumothorax.

[Preoperatory sonography efficiency in paediatric patients with cholelithiasis undergoing laparoscopic cholecystectomy].

Introduction: Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography.
