Does the ArthroSim™ Shoulder Simulation Discriminate Between the Novice and Expert User? An External Validation Study of the ArthroSim™ Shoulder Arthroscopy Simulator.

Introduction: Our aim is to investigate the face validity and the construct validity of the ArthroSim™ virtual reality shoulder arthroscopy simulator (Touch of Life Technologies, Inc., Aurora, Colorado).

Materials And Methods: Fifteen doctors participated, with five from each of the following levels: novice with no arthroscopies performed, intermediate with less than 50 arthroscopies performed, and expert with over 100 arthroscopies performed.

Tricuspid valve replacement with mechanical versus biological prostheses: a systematic review and meta-analysis.

Background And Objective: Tricuspid valve replacement (TVR) is required when repair is not feasible, and it continues to be a relatively high-risk procedure owing to the complex medical and/or surgical profile of patients. The choice between mechanical and biological prostheses for TVR remains a subject of debate owing to their distinct advantages and disadvantages. This study aimed to analyse and compare the clinical outcomes of these two types of prostheses in the tricuspid position.

Is there a Possible Association between Multiple Myeloma Relapse and Coronavirus Disease 2019 Vaccination? A Case Report.

Due to the high morbidity and mortality of the coronavirus disease 2019 (COVID-19) in patients with malignancy, the necessity of vaccination in this group of patients became particularly important. Although a large number of studies have reported the safety of COVID-19 vaccination in multiple myeloma (MM) patients, the effect of the COVID-19 vaccine on MM relapse has not yet been reported. Here, we report a case of a possible association between relapse of MM and COVID-19 vaccination with Sinopharm, an inactivated virus vaccine, in a patient with MM who has remained in complete remission for about 4 years.

Pregnancy outcomes in renal transplant recipients: A systematic review and meta-analysis.

Background: Kidney transplantation is a superior treatment for end-stage renal disease (ESRD), compared with hemodialysis, offering better quality of life and birth outcomes in women with ESRD and lower fertility rates.

Objectives: To investigate the pregnancy, maternal, fetal, and graft outcomes following kidney transplantation in women with ESRD and evaluate the improvements in quality of life and associated risks.

Design: A systematic review and meta-analysis performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Meta-analysis of Observational Studies in Epidemiology guidelines.
