Background: Despite patent ductus arteriosus closure in premature infants is a relatively fast procedure, it involves specific steps for equipment exchange and the use of a 4-Fr catheter, which may be large for tiny infants, potentially causing haemodynamic instability or tricuspid valve regurgitation.
Objectives: This study aims to describe the early experience with a new technique designed to simplify transcatheter patent ductus arteriosus closure in premature infants. It enables the closure using the KA micro plug device via a single microcatheter without equipment exchanges and contrast exposure.

Multifunctional devices based on van der Waals heterojunctions have drawn significant attention owing to their portable size, low power consumption and various application scenarios. However, high fabrication equipment requirements, complex device structures and limited operating conditions hinder their potential value. Herein, multifunctional UV photodetect-memristors based on GaS/graphene/GaN van der Waals heterojunctions area selective deposition have been proposed for the first time.

Background: We evaluated UK nurses' preferences for pediatric hexavalent vaccine attributes.
Research Design And Methods: In a discrete-choice experiment study, 150 nurses chose between 2 hypothetical pediatric hexavalent vaccines with varying attribute levels (device type, plastic in packaging, time on the market, and time the vaccine can stay safely at room temperature) in a series of choice questions. Using random-parameters logit-model estimates, conditional relative attribute importance (CRAI) and odds ratios (ORs) were calculated.

Bone defects are a prevalent issue resulting from various factors, such as trauma, degenerative diseases, congenital disabilities, and the surgical removal of tumors. Current methods for bone regeneration have limitations. In this context, the fusion of tissue engineering and microfluidics has emerged as a promising strategy in the field of bone regeneration.

In this work, what we believe to be a novel electrostatic 2-DOF micromirror structure with double-biased torsional axes is proposed. By introducing internal resonance, synchronous motions of the two axes with a locked frequency ratio under a single driving force were achieved within a wide frequency range.
