First‐trimester prediction and prevention of preterm pre‐eclampsia in women with chronic hypertension

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 613-622, May 2026.
ABSTRACT Objectives To evaluate the effect of aspirin on gestational age at delivery due to preterm pre‐eclampsia (PE) in women with chronic hypertension (CH), to assess the predictive performance of the Fetal Medicine Foundation (FMF) first‐trimester competing‐risks model for preterm PE in this high‐risk group and to evaluate how parity, previous PE ...

Cost–benefit analysis of first‐trimester pre‐eclampsia screening: comparison of multivariable Gaussian algorithm with and without placental growth factor

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 162-167, February 2026.
ABSTRACT Objective Pre‐eclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Early identification of high‐risk pregnancies in the first trimester allows preventive treatment with low‐dose aspirin. This study aimed to evaluate whether multivariable Gaussian algorithm‐based PE screening strategies, with and without

Enhancing multitasking capacity: An acoustic tagging and sampling methodology for the spiny butterfly ray (Gymnura altavela) in the Canary Islands

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
To overcome challenges in studying elusive benthic elasmobranchs, a comprehensive, rapid methodology was developed and applied to 133 Spiny Butterfly Rays in Gran Canaria and Tenerife between 2020 and 2024. This approach integrated internal tagging with acoustic and external T‐bar tags, alongside biological sampling and ultrasound assessments, all ...
