Cost-benefit analysis of first-trimester pre-eclampsia screening: comparison of multivariable Gaussian algorithm with and without placental growth factor. [PDF]
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

The OLGIMA system for gastric cancer risk assessment. A useful method based on the histological Sydney consensus. [PDF]
The new OLGIMA method for histological gastric cancer risk assessment is based on the severity of glandular atrophy and intestinal metaplasia, in both antrum and corpus, according to the Updated Sydney classification. The highest score of either atrophy or intestinal metaplasia from each location will be used for the final OLGIMA stage.

Fetoscopic two-layer closure for open neural tube defects: prospective study of obstetric, surgical and perinatal outcomes in the first 50 cases. [PDF]
ABSTRACT Objective Fetoscopic repair for open neural tube defects (ONTDs) has gained acceptance among leading groups, although it remains controversial owing to the lack of a standardized neurosurgical technique. In 2018, our group described a new fetoscopic two‐layer procedure with an exteriorized uterus for ONTD reconstruction.

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States. [PDF]
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the
