Risk and Risk Estimation of Placental Abruption [PDF]

open access: yesObstetrical & Gynecological Survey, 2006
Several variables related to increased risk of placental abruption are also risk factors for venous thromboembolism. Prior second trimester-, third trimester, and repeated fetal loss are reported to be associated to thrombophilias. However, it is yet not known if they are also related to placental abruption.A retrospective case-control study of 161 ...

Deep neural network improves the estimation of polygenic risk scores for breast cancer [PDF]

open access: yesJournal of Human Genetics, 2020
Polygenic risk scores (PRS) estimate the genetic risk of an individual for a complex disease based on many genetic variants across the whole genome. In this study, we compared a series of computational models for estimation of breast cancer PRS.
