Telemedicine ultrasound assessment for placenta accreta spectrum: Utility and interobserver reliability of asynchronous remote imaging review.
Int J Gynaecol Obstet

Objective: Management of patients with placenta accreta spectrum (PAS) by trained multidisciplinary teams is associated with improved outcomes. Ultrasound can predict intraoperative risks, but expert ultrasound imaging of PAS is often limited. Telemedicine is used increasingly in obstetrics, permitting expert consultation when essential resources are not available locally.

Article Synopsis
- The study evaluates a proposed ultrasound checklist for detecting placenta accreta spectrum (PAS) in patients with a high likelihood of the condition, aiming to see how effective it is in identifying confirmed PAS cases.
- Conducted over five years, the research included patients who had ultrasound assessments for PAS suspicion, with diagnoses confirmed through surgical and histopathological findings.
- Results showed an 80.7% PAS diagnosis among participants, with the third-trimester ultrasound displaying a sensitivity of 84% and specificity of 73%, highlighting key ultrasound features—abnormal placental lacunae and myometrial thinning—as strongly associated with PAS.
In severe Placenta Accreta Spectrum (PAS), trophoblasts gain deep access in the myometrium (placenta increta). This study investigated alterations at the fetal-maternal interface in PAS cases using a systems biology approach consisting of immunohistochemistry, spatial transcriptomics and proteomics. We identified spatial variation in the distribution of CD4, CD3 and CD8 T-cells at the maternal-interface in placenta increta cases.

We aim to validate our model using an additional dataset. Secondly, we explore whether the performance is improved using a new approach to develop a new multivariate radiomics model.

The aim of this study was to provide an analysis of injury-force-mechanisms in TPFs, including axial rotation.
Methods: The injury-force mechanism was determined for 203 fractures that presented over a period of 3.
