Cost Effectiveness of Fixation Versus Total Hip Arthroplasty in Vancouver B2 Periprosthetic Femur Fractures: A Predictive Markov Analysis.

Background: Although Vancouver B2 periprosthetic fractures (PPFs) have been historically managed with revision total hip arthroplasty (rTHA), open reduction and internal fixation (ORIF) has been proposed as an alternative option for reasons including lower cost and surgical time. The purpose of this study was to, therefore, create a Markov model to assess the cost effectiveness of ORIF versus rTHA for Vancouver B2 periprosthetic femur fractures and evaluate various inflection points for varying costs and outcome measures.

Methods: A Markov model was built using discrete and mutually exclusive health states of the hypothetical patient with Vancouver B2 PPF.

Survivorship of Periprosthetic Joint Infection in Unicompartmental Knee Arthroplasty: A Single Healthcare System's 23-Year Experience.

Introduction: Unicompartmental knee arthroplasty (UKA) is increasingly favored in clinical practice due to its favorable long-term survival rates, positive clinical outcomes, and expedited recovery. Periprosthetic joint infections (PJIs) remain a formidable complication in knee arthroplasty, and guidelines for the management are limited. This study aims to assess the failure rates of débridement, antibiotics, and implant retention (DAIR) in UKAs, providing insights into optimal treatment management and infection-free survival for PJI in this context.

Oral obeldesivir provides postexposure protection against Marburg virus in nonhuman primates.

The recent outbreak of Marburg virus (MARV) in Rwanda underscores the need for effective countermeasures against this highly fatal pathogen, with case fatality rates reaching 90%. Currently, no vaccines or approved treatments exist for MARV infection, distinguishing it from related viruses such as Ebola. Our study demonstrates that the oral drug obeldesivir (ODV), a nucleoside analog prodrug, shows promising antiviral activity against filoviruses in vitro and offers significant protection in animal models.

Multidrug resistant : A study on its pathogenesis and therapeutics.

The overuse of antibiotics has led to the global dissemination of , an increasingly challenging nosocomial pathogen. This review explores the medical significance along with the diverse resistance ability of . Intensive care units (ICUs) serve as a breeding ground for , as these settings harbour vulnerable patients and facilitate the spread of opportunistic microorganisms.
