Prognostic Impact of Primary Tumor Size in Thymic Epithelial Tumor: An NCDB-Based Study.

Background: Thymic epithelial tumor (TET) staging has been based on Masaoka-Koga systems or the 8th edition of the TNM classification, which do not use tumor size as a T descriptor. The 9th edition of the TNM classification incorporates tumor size; however, the study on which this classification is based included only 4.4% of patients from North America.

Utility of Orthosis in the Conservative Treatment of Proximal Phalanx Fractures: A Preliminary Study in Healthy Participants.

Background: The standard treatment for the conservative management of a proximal phalanx fracture of the little finger involves immobilizing the fracture site with a cast. However, cast immobilization presents challenges in maintaining hygiene during treatment and restricts the fine motor movements of the fingers. In this study, we developed a removable orthosis that immobilizes only the ring and little fingers.

CaMKII-dependent non-canonical RIG-I pathway promotes influenza virus propagation in the acute-phase of infection.

Ca/calmodulin-dependent protein kinase II (CaMKII) is one of hundreds of host-cell factors involved in the propagation of type A influenza virus (IAV), although its mechanism of action is unknown. Here, we identified CaMKII inhibitory peptide M3 by targeting its kinase domain using affinity-based screening of a tailored random peptide library. M3 inhibited IAV cytopathicity and propagation in cells by specifically inhibiting the acute-phase activation of retinoic acid-inducible gene I (RIG-I), which is uniquely regulated by CaMKII.

Evaluation of the safety of drainless uniportal video-assisted thoracoscopic surgery for the treatment of primary spontaneous pneumothorax: a two-institution retrospective study.

Background: Uniportal video-assisted thoracoscopic surgery (U-VATS) offers good cosmetic outcomes with minimal pain for the treatment of primary spontaneous pneumothorax (PSP). Moreover, the early removal of postoperative chest drains reduces postoperative pain and hospitalization duration for patients with PSP. We aimed to investigate the safety and feasibility of drainless U-VATS in patients with PSP and compare postoperative outcomes between specialists and residents.
