Contour Dice loss for structures with Fuzzy and Complex Boundaries in Fetal MRI [PDF]

arXiv, 2022
Volumetric measurements of fetal structures in MRI are time consuming and error prone and therefore require automatic segmentation. Placenta segmentation and accurate fetal brain segmentation for gyrification assessment are particularly challenging because of the placenta fuzzy boundaries and the fetal brain cortex complex foldings.

Monthly buprenorphine depot injection (SUBLOCADE®) for opioid use disorder during pregnancy

The American Journal on Addictions, EarlyView.
Abstract Background and Objectives Untreated opioid use disorder (OUD) in pregnancy is associated with adverse obstetrical outcomes, maternal morbidity, and maternal mortality. This article will inform clinicians about the use of monthly extended‐release buprenorphine (BUP‐XR, SUBLOCADE®) to treat OUD during pregnancy and postpartum.

Type III Vasa Previa Associated with Resolution of a Low-Lying Placenta: Case Report and Literature Review

American Journal of Perinatology Reports
Vasa previa occurs when fetal vessels lie above the cervical os. A novel type of vasa previa, known as type III, is characterized by an abnormal branching of fetal vessels from the placenta in the absence of velamentous cord insertion (as seen in type I)

Proactive Insulin Escalation for Antenatal Betamethasone‐Induced Hyperglycaemia in Women With Diabetes: A Prospective Cohort Study

Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background In patients with diabetes, antenatal glucocorticoids can induce transient maternal hyperglycaemia for approximately 72 h. This may be associated with adverse outcomes, including neonatal hypoglycaemia, prompting recommendations for prophylactic increases in insulin by some expert groups; however, there are no validated protocols.

Risk factors, prenatal diagnosis, and outcome of posterior placenta accreta spectrum disorders in patients with placenta previa or low‐lying placenta: A multicenter study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Prenatal ultrasound has a low diagnostic accuracy in detecting posterior compared to anterior placenta accreta spectrum disorder. However, posterior placenta accreta spectrum disorders are associated with a lower risk of hysterectomy compared to cases with anterior implantation. Abstract Introduction Placenta accreta spectrum (PAS) disorders occur when

Unexpected uterine body placenta accreta spectrum with placenta previa in a subsequent pregnancy after uterine artery embolization: a case report

BMC Pregnancy and Childbirth, 2022
Background A subsequent pregnancy after uterine artery embolization (UAE) raises several concerns, one of which is placenta accreta spectrum (PAS). Placenta previa is the strongest risk factor for PAS, which is most likely to occur in the lower uterine ...
