Dysplasia and Colorectal Cancer Surveillance in Ulcerative Colitis Patients in Latin America: Real-World Data.

Background: The prevalence of colorectal cancer (CRC) in patients with ulcerative colitis (UC) is higher than in the general population, in Latin America there is a progressive increase of UC, and information about CRC screening in inflammatory bowel disease (IBD) is scarce. The aim of this study was to analyze the findings of endoscopic surveillance of CRC in patients with IBD according to available technology.

Methods: Multicenter, cross-sectional, analytical study conducted in Latin American countries, in patients with UC, predominantly with more than 8 years of diagnosis and different degrees of disease activity.

Higher PAPP-A Values in Pregnant Women Complicated with Preeclampsia Than with Gestational Hypertension.

The purpose of this study is to compare the levels of maternal serum pregnancy-associated plasma protein-A at the first trimester in pregnancies complicated by impaired placental diseases, such as preeclampsia (PE), intrauterine fetal growth restriction (IUGR), and gestational hypertension (GH), with those in pregnancies without the development of any of these outcomes to expand the knowledge of how this protein behaves in the different impaired placental diseases. This current work is an observational study based on a prospective cohort. Pregnancy-associated plasma protein-A was measured in 422 patients who had completed maternal-perinatal outcomes.

First trimester placental growth factor in maternal blood and placenta related disorders.

Methods: Observational study based on a prospective cohort of 422 pregnant women. PlGF values were compared between the different groups (preeclampsia, intrauterine growth restriction (IUGR), gestational hypertension or normal group-patients without impaired placentation diseases).
