The Influence of Cyber Victimization, Internet Use, and Perception of Cyberbullying-on-Cyberbullying Perpetration among Korean Adults: A National Sample-Based Study.

Background: Although cyberbullying has emerged as a serious problem even among adults, most researches have been conducted on the adolescents. We aimed to verify the independent effects of cyber victimization, internet use, and the perception of cyberbullying-on-cyberbullying perpetration in South Korea adults.

Methods: The data of 1500, 20s to 50s Korea adults from the 2019 Survey on the Cyberbullying conducted by the National Information Society Agency were used.

To plate, or not to plate? A systematic review of functional outcomes and complications of plate fixation in patellar fractures.

Purpose: Poor outcomes and high complication and reoperation rates have been reported with tension-band wiring (TBW) in the management of patellar fractures and particularly the comminuted ones. The purpose of this study was to investigate the functional outcomes and complication rates of patellar fractures managed with open reduction and internal fixation (ORIF) with a plate.

Methods: MEDLINE, EMCare, CINAHL, AMED and HMIC were searched, and the PRISMA guidelines were followed.

Visualising the Future of Orthopaedic Surgery: A Novel Application of Wireless Smart Glasses to Visualise Intraoperative Imaging.

Smart glasses can provide a heads-up display of advanced imaging intraoperatively. In recent years, growing attention has been drawn to the use of smart glasses as an assistive technology to improve both efficiency and ergonomics in a surgical setting. Previous studies have reported improved surgical accuracy, efficiency, and ergonomics with its usage, but its effectiveness as a form of intraoperative heads-up display remains elusive in the context of orthopaedics.

Point-of-care screening for heart failure with reduced ejection fraction using artificial intelligence during ECG-enabled stethoscope examination in London, UK: a prospective, observational, multicentre study.

Background: Most patients who have heart failure with a reduced ejection fraction, when left ventricular ejection fraction (LVEF) is 40% or lower, are diagnosed in hospital. This is despite previous presentations to primary care with symptoms. We aimed to test an artificial intelligence (AI) algorithm applied to a single-lead ECG, recorded during ECG-enabled stethoscope examination, to validate a potential point-of-care screening tool for LVEF of 40% or lower.

Extraction-free in situ derivatisation of timosaponin AIII using direct analysis in real time TOF/MS.

Introduction: Direct analysis in real time (DART) TOF/MS has been used for mass information of various non-polar phytochemicals in raw material with no sample preparation. However, low ionisation efficiency for polar compounds including glycosides limits its extensive use in the field of phytochemical analysis.

Objective: In order to develop a direct analysis method for polar glycosides using in situ derivatisation, which improves ionisation efficiency of hydrophilic glycosides.
