Infection control for COVID-19 in hospital examination room.

Healthcare providers are vulnerable to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) because of their close proximity to patients with coronavirus disease 2019. SARS-CoV-2 is mainly transmitted via direct and indirect contact with respiratory droplets, and its airborne transmission has also been identified. However, evidence for environmental factors is scarce, and evidence-based measures to minimize the risk of infection in clinical settings are insufficient.

Endoscopic laser treatment for urine leakage caused by an isolated calyx after robot-assisted partial nephrectomy.

Introduction: An isolated calyx is a rare complication in which the renal calyx and pelvis are disconnected. The treatment is often complicated.

Case Presentation: An 81-year-old man underwent robot-assisted partial nephrectomy for the treatment of renal cell carcinoma (cT1bN0M0).

Novel bone microenvironment model of castration-resistant prostate cancer with chitosan fiber matrix and osteoblasts.

The interaction between prostate cancer cells and osteoblasts is essential for the development of bone metastasis. Previously, novel androgen receptor axis-targeted agents (ARATs) were approved for metastatic castration-naïve and non-metastatic castration-resistant prostate cancer (CRPC); both of which are pivotal for investigating the association between the bone microenvironment and tumors. The present study established a novel 3D microenvironment model that simulated the bone microenvironment of CRPC, and evaluated the drug susceptibility of ARATs and the efficacy of the combination of abiraterone and dutasteride.
