Multi-centre deep learning for placenta segmentation in obstetric ultrasound with multi-observer and cross-country generalization.

The placenta is crucial to fetal well-being and it plays a significant role in the pathogenesis of hypertensive pregnancy disorders. Moreover, a timely diagnosis of placenta previa may save lives. Ultrasound is the primary imaging modality in pregnancy, but high-quality imaging depends on the access to equipment and staff, which is not possible in all settings.

Does group size matter during collaborative skills learning? A randomised study.

Background: Collaborative skills learning in the form of dyad learning compared with individual learning has been shown to lead to non-inferior skills retention and transfer. However, we have limited knowledge on which learning activities improve collaborative skills training and how the number of collaborators may impact skills transfer. We explored the effects of skills training individually, in dyads, triads or tetrads on learning activities during training and on subsequent skills transfer.

Business as (un)usual: A qualitative study of clerkship experiences during a health crisis.

Introduction: During a health crisis, hospitals must prioritise activities and resources, which can compromise clerkship-based learning. We explored how health crises affect clinical clerkships using the COVID-19 pandemic as an example.

Methods: In a constructivist qualitative study, we conducted 22 semi-structured interviews with key stakeholders (i.

Collecting Validity Evidence for Simulation-Based Assessment of Point-of-Care Ultrasound Skills.

Objectives: The aim of this study was to examine the validity of a simulator test designed to evaluate focused assessment with sonography for trauma (FAST) skills.

Methods: Participants included a group of ultrasound novices (n = 25) and ultrasound experts (n = 10). All participants had their FAST skills assessed using a virtual reality ultrasound simulator.

Internal Hernia in Pregnant Women After Gastric Bypass: a Retrospective Register-Based Cohort Study.

Background And Aims: Pregnant women who have previously had laparoscopic Roux-en-Y gastric bypass surgery are increasingly seen in the acute surgical care setting with abdominal pain due to internal hernia. With this study, we want to contribute with our experience and to present our local surgical guidelines concerning this particularly vulnerable patient group.

Materials And Method: This article is a retrospective study on prospectively collected data.
