Improved left atrial catheterization efficiency and consistency using a novel steerable transseptal puncture sheath.

Background: While steerable sheaths are widely used to improve catheter stability and contact force during radiofrequency (RF) catheter ablation in patients with atrial fibrillation (AF), steerable sheaths are less commonly used during transseptal puncture. This study evaluated whether left atrial catheterization efficiency can be improved using the VersaCross combined steerable sheath and transseptal system compared to previous standard workflow.

Methods: This study retrospectively analyzed AF ablation performed using the VersaCross Workflow consisting of VersaCross steerable sheath and RF wire for transseptal puncture and catheter ablation (VCW) to the standard workflow using a fixed curve sheath with RF needle followed by exchange for an Agilis steerable sheath for catheter ablation (STW).

Preliminary stage in the development of an artificial intelligence algorithm: Variations between 100 surgeons in phase annotation in a video of internal fixation of distal radius fracture.

Introduction: In order to be used naturally and widely, an artificial intelligence algorithm of phase detection in surgical videos presupposes an expert consensus defining phases.

Objectives: The aim of the present study was to seek consensus in defining the various phases of a surgical technique in wrist traumatology.

Methods: Three thousand two hundred and twenty-nine surgeons were sent a video showing anterior plate fixation of the distal radius and a questionnaire on the number of phases they distinguished and the visual cues signaling the beginning of each phase.

[The Importance of Socioeconomic Status in the Occurrence of Mental Health Problems in 11- to 17-Year-Old Girls and Boys in Germany: Results of KiGGS Wave 2 (2014-2017)].

Aim Of The Study: The aim of the study was to investigate the distribution pattern of mental health problems (emotional problems, conduct problems, peer problems, hyperactivity) among different socioeconomic groups of 11- to 17-year-old girls and boys.

Methods: Data for this study were obtained from the "German Health Interview and Examination Survey for Children and Adolescents KiGGS Wave 2" (2012-2014, n=15,023). The data on 11- to 17-year-old girls and boys (n=6599) was analyzed overall and separately for two age groups.

High-throughput screening of toxicants that modulate extravillous trophoblast migration.

Migration and subsequent invasion of extravillous trophoblasts into the uterus is essential for proper formation of the placenta. Disruption of these processes may result in poor pregnancy outcomes including preeclampsia, placenta accreta, fetal growth restriction, or fetal death. Currently, there are several methods for quantifying cell migration and invasion in vitro, each with limitations.
