Cobalt-Chromium-Molybdenum Femoral Knee Implant Damage Correlates with Elevated Periprosthetic Metal Concentrations.

Background: Total knee arthroplasty (TKA) device systems frequently include cast cobalt chrome alloy (CoCrMo) femoral components. However, compared to total hip arthroplasty (THA), gaps persist in our understanding of the correlations between femoral component damage, local metal release, and potential biological effects. Additionally, it remains unclear how TKA metal release affects clinical success or patient satisfaction.

Effects of temperature and nutrient load on the interaction of Vibrio parahaemolyticus and plastic pollution in the marine environment.

Plastic pollution in the marine environment harbors a diverse community of microorganisms called the plastisphere. The plastisphere has been found to contain potential pathogenic species of concern to both marine organisms and human health. This study examines the ability of plastic to harbor Vibrio parahaemolyticus, the leading cause of seafood-borne illness around the globe, in varying environmental conditions.

Polytomous explanatory item response models for item discrimination: Assessing negative-framing effects in social-emotional learning surveys.

Modeling item parameters as a function of item characteristics has a long history but has generally focused on models for item location. Explanatory item response models for item discrimination are available but rarely used. In this study, we extend existing approaches for modeling item discrimination from dichotomous to polytomous item responses.

Development and Validation of a Teaching Module for Prescription Writing for Dental Students: A Randomized Controlled Trial.

Objectives: Dentists commonly encounter patients with complex medical comorbidities that require an advanced level of competence in the art of prescription writing. However, the current structure of dental education often places limited emphasis on this critical skill. This study aimed to develop and validate an innovative teaching module designed to enhance prescription-writing skills for dental students, with a specific focus on patients with medical comorbid conditions.
