Background: Low energy intracardiac cardioversion has recently been introduced into clinical practice to treat both acute and chronic atrial fibrillation. It has also been suggested that low energy intracardiac cardioversion has a higher efficacy rate in restoring sinus rhythm than conventional external cardioversion.
Methods: A prospective study was started in 41 patients (mean age 64.5 years) with chronic atrial fibrillation (mean duration 6.5 months), in order to obtain more data on low energy intracardiac cardioversion concerning: 1) time required to perform low energy intracardiac cardioversion by single venous femoral approach; 2) acute efficacy; 3) incidence of complications; 4) persistence of sinus rhythm after 1 month.
Results: Twenty patients had right atrium-coronary sinus (Group A) and 20 right atrium-left pulmonary artery (Group B) electrode configuration for defibrillation. In 1 patient the configuration was not available. In all patients (100%) sinus rhythm was acutely restored. No statistically significant differences were found between the two groups concerning mean energy and impedance required to obtain cardioversion. With mild sedation the discomfort induced by the electrical shock was minimal or mild. Only 44% of patients were in sinus rhythm 1 month after low energy intracardiac cardioversion, in spite of adequate pharmacological therapy.
Conclusions: Low energy intracardiac cardioversion by single venous femoral approach may be considered a very effective and not time consuming procedure in acutely restoring sinus rhythm, with low complication rate; in addition the procedure was well accepted by all patients.

Although metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have been extensively used as fluorescent-based antibiotic sensors, newly developed hydrogen-bonded organic frameworks (HOFs) are largely unexplored toward this direction. To realize this, the luminescent HOFs must be stable in water as the analytes are mostly found in water-based effluents in environments. In addition, HOFs should be equipped with specific recognition sites in order to direct the discrimination among the antibiotics.

Transition metal carbides, known as MXenes, particularly TiCT, have been extensively explored as promising materials for electrochemical reactions. However, transition metal carbonitride MXenes with high nitrogen content for electrochemical reactions are rarely reported. In this work, transition metal carbonitride MXenes incorporated with Pt-based electrocatalysts, ranging from single atoms to sub-nanometer dimensions, are explored for hydrogen evolution reaction (HER).

Influenza is a highly contagious respiratory illness that imposes a significant global burden. Antiviral neuraminidase inhibitors (NAIs) such as oseltamivir (OC) have been proven essential, but the emergence of resistant viral strains necessitates the development of novel therapies. This study explored the potential of natural products as alternative NAIs.

Metallic nanowires have served as novel materials for soft electronics due to their outstanding mechanical compliance and electrical properties. However, weak adhesion and low mechanical robustness of nanowire networks to substrates significantly undermine their reliability, necessitating the use of an insulating protective layer, which greatly limits their utility. Herein, we present a versatile and generalized laser-based process that simultaneously achieves strong adhesion and mechanical robustness of nanowire networks on diverse substrates without the need for a protective layer.
