Placental vessel segmentation and registration in fetoscopy: Literature review and MICCAI FetReg2021 challenge findings.

Fetoscopy laser photocoagulation is a widely adopted procedure for treating Twin-to-Twin Transfusion Syndrome (TTTS). The procedure involves photocoagulation pathological anastomoses to restore a physiological blood exchange among twins. The procedure is particularly challenging, from the surgeon's side, due to the limited field of view, poor manoeuvrability of the fetoscope, poor visibility due to amniotic fluid turbidity, and variability in illumination.

Toward a navigation framework for fetoscopy.

Purpose: Fetoscopic laser photocoagulation of placental anastomoses is the most effective treatment for twin-to-twin transfusion syndrome (TTTS). A robust mosaic of placenta and its vascular network could support surgeons' exploration of the placenta by enlarging the fetoscope field-of-view. In this work, we propose a learning-based framework for field-of-view expansion from intra-operative video frames.

Psychological well-being and healthy communities: Women as makers of relational well-being by social street strategies.

This paper presents a Social Street experience born of the perception of a lack of solidarity among neighbors and the desire to create a new neighborhood model. The goal was to explore the Social Street phenomenon through the relationship between individuals and their community. Furthermore, the goals include promoting the awareness of the critical issues of the territory to activate empowerment and change, analyzing the effectiveness of Social Street through the study of social networks, and investigating differences in social participation and in social cohesion.
