Article Synopsis
  • - This study assessed how accurately SARS-CoV-2 RNA can be detected in saliva samples, comparing those treated with guanidine and without, against traditional nasopharyngeal swabs (NPS) used as a reference.
  • - Results showed that raw saliva had a 100% sensitivity for detecting the virus, while the sensitivity for saliva treated with guanidine-based and guanidine-free inactivators was lower, at 65.9% and 82.9% respectively.
  • - Despite the reduced sensitivity in treated saliva, the study found that these inactivated samples could still provide reliable results for diagnosing COVID-19, which is beneficial for minimizing the risk of virus transmission.

High-flow nasal cannula (HFNC) can be effective in treating type 1 respiratory failure by reducing the severity of coronavirus disease 2019 (COVID-19). The purpose of this study was to assess the reduction of disease severity and safety of HFNC treatment in patients with severe COVID-19. We retrospectively observed 513 consecutive patients with COVID-19 admitted to our hospital from January 2020 to January 2021.

Introduction: To date, the treatment option for tachyarrhythmia is classified into drug therapy, catheter ablation, and implantable device therapy. However, the efficacy of the antiarrhythmic drugs is limited. Although the indication of catheter ablation is expanding, several fatal tachyarrhythmias are still refractory to ablation.

Background: Ventricular arrhythmia inducibility is one of the ideal endpoints of ventricular tachycardia (VT) ablation. However, it may be challenging to implement programmed electrical stimulation (PES) at the end of the procedure under several circumstances. The long-term outcome of patients who did not undergo PES after VT ablation remains largely unknown.
