Exploring α-ψ-ϕ contractive mapping: novel fixed point theorems in complete b-metric spaces.

This paper explores the concept of contractive mappings, contributing to the advancement of self-map extensions and fixed-point theorems within b-metric spaces. We introduce a new class of contractive mappings and demonstrate how they extend traditional contraction principles, offering a broader framework for analyzing fixed points in non-standard spaces. The main result of this study is a generalization of existing fixed-point theorems, supported by comprehensive corollaries, illustrative examples, and rigorous proofs.

Feasibility of intra-amniotic digoxin administration by obstetrics and gynecology trainees to induce fetal demise prior to medical abortion beyond 20 weeks.

Background: Transient fetal survival is one issue that providers may face while managing late second-trimester abortion. Induction of fetal demise using digoxin and other means has been widely performed by maternal-fetal medicine and family planning subspecialists worldwide. However, there are no data available in Ethiopia as regards preventing transient fetal survival in late second-trimester medical termination of pregnancy.
