Severe Panton-Valentine-Leukocidin-Positive Infections in Pediatric Age: A Case Report and a Literature Review.

Infections caused by S. aureus strains encoding Panton-Valentine leukocidin (PVL-SA) have become increasingly relevant in community settings and can cause severe conditions in pediatric populations. We present the pediatric case of an invasive disease caused by PVL-SA and provide a literature review of severe manifestations caused by these strains in children.

Atrial fibrillation management in older hospitalized patients: Evidence of a poor oral anticoagulants prescriptive attitude from the Italian REPOSI registry.

Atrial fibrillation (AF) prevalence increases in older patients which also show a high thromboembolic risk. Oral anticoagulants (OACs) are recommended to prevent cardioembolic events and direct oral anticoagulants (DOACs) improved anti-thrombotic treatment. However, the benefits/risks of anticoagulant in older patients still need to be completely defined.

Safety of High-Dose Vitamin C in Non-Intensive Care Hospitalized Patients with COVID-19: An Open-Label Clinical Study.

: Vitamin C has been used as an antioxidant and has been proven effective in boosting immunity in different diseases, including coronavirus disease (COVID-19). An increasing awareness was directed to the role of intravenous vitamin C in COVID-19. : In this study, we aimed to assess the safety of high-dose intravenous vitamin C added to the conventional regimens for patients with different stages of COVID-19.

WNT Oncogenic Transcription Requires MYC Suppression of Lysosomal Activity and EPCAM Stabilization in Gastric Tumors.

Background & Aims: WNT signaling is central to spatial tissue arrangement and regulating stem cell activity, and it represents the hallmark of gastrointestinal cancers. Although its role in driving intestinal tumors is well characterized, WNT's role in gastric tumorigenesis remains elusive.

Methods: We have developed mouse models to control the specific expression of an oncogenic form of β-catenin (CTNNB1) in combination with MYC activation in Lgr5 cells of the gastric antrum.
