Endocrine disrupting chemicals (EDCs) are chemicals that have the capacity to interfere with normal endocrine systems. Two EDCs, bisphenol A (BPA) and triclosan (TCS), are mass-produced and widespread. They both have estrogenic properties and similar chemical structures and pharmacokinetic features and have been detected in human fluids and tissues. Clinical evidence has suggested a positive association between BPA exposure and implantation failure in IVF patients. Studies in mouse models have suggested that preimplantation exposure to BPA and TCS can lead to implantation failure. This paper reviews the relationship between preimplantation exposure to BPA and TCS and implantation failure and discusses the remaining problems and possible solutions.

This updated Heart Valve Collaboratory framework addresses the growing concern for transcatheter valve failure (TVF) following transcatheter aortic valve replacement (TAVR). With the increasing volume of redo-TAV and surgical TAV explantation, there is a critical need for standardized pathways and protocols for evaluating TVF using echocardiography and cardiac computed tomography (CT) angiography. This document clarifies prior definitions of bioprosthetic valve deterioration and bioprosthetic valve failure in a practical, imaging directed context for TAVR.

Purpose: This study assessed the impact of the buccal bone on hard and soft tissues in submerged and non-submerged immediate implants using a minipig model.
Methods: Sixty-five titanium implants (Camlog Progressive Line) were placed in four minipigs immediately after tooth extraction. All non-submerged (NSM) implants received a mechanically induced buccal bone defect (NSM-BD), whereas the submerged group (SM) was classified as defective (SM-BD) and intact (SM-BI).

Objective: To evaluate device survival and identify risk factors for failure in pediatric cochlear implant (CI) surgery to guide strategies for minimizing failure rates and improving survival outcomes.
Methods: A retrospective analysis was conducted on pediatric patients who underwent CI surgery at the Children's Hospital, Zhejiang University School of Medicine, from September 2008 to September 2023. Device survival was assessed using the Kaplan-Meier method while independent factors influencing device survival were analyzed using the log-rank test and Cox regression model.

Background: In cardiovascular engineering, the recent introduction of soft robotic technologies sheds new light on the future of implantable cardiac devices, enabling the replication of complex bioinspired architectures and motions. To support human heart function, assistive devices and total artificial hearts have been developed. However, the system's functionality, hemocompatibility, and overall implantability are still open challenges.

Background: Valgus osteotomy is a femoral head-preserving surgery to treat femoral neck non-union in young, active patients. The traditional approach, however, causes medialisation of the femoral shaft during valgus correction, which alters femoral anatomy and complicates conversion to total hip arthroplasty if head osteosynthesis fails. This study aims to outline a novel surgical technique, medial opening wedge valgus intertrochanteric osteotomy (VITO), and evaluate its clinical and radiographic outcomes, focusing on restoring hip biomechanics and improving union rates.
