Currently, there is no consensus on the treatment protocol for ossicular chain trauma. This study aims to investigate the classification and treatment strategies for traumatic ossicular chain dislocation. We retrospectively analyzed 15 patients. ⋯ Pneumolabyrinth was detected in 2 patients. We propose a novel classification system for traumatic ossicular chain dislocation. Treatment strategies should be tailored according to the specific trauma type.

Background and objective: The aim of this research is to investigate whether the GRIm score serves as a novel prognostic tool for predicting the survival rates among early breast cancer patients undergoing surgical treatment. Methods: This retrospective study included 313 cases of breast cancer patients hospitalized in our hospital from January 2015 to November 2015. All enrolled patients received surgery and had no metastasis. ⋯ Nomograms exhibited excellent predictive performance for DFS (C-index: 0.823) and OS (C-index: 0.807). Conclusions: GRIm score serves as a predictive tool for assessing the prognosis of early breast cancer patients. Nomograms based on GRIm score show good prediction ability.

Interleukin 41 As A Potential Predictor of Bio-Therapy Efficacy In Patients With Rheumatoid Arthritis: A Prospective Observational Study.
Introduction: A novel immunomodulatory cytokine IL-41 is associated with the pathogenesis of Graves disease, Kawasaki disease, gout, psoriatic arthritis, and rheumatoid arthritis (RA). We aimed to evaluate serum IL-41 level as a biomarker of the RA and disease activity treatment efficacy and patient responses. We also wanted to determine eventual potential predictors of IL-41 concentrations. ⋯ The only statistically significant predictor of higher IL-41 values was smoking. Conclusion: IL-41 may be a new potential biomarker that can help physicians evaluate treatment efficacy and predict patient responses. Smoking status is associated with the higher concentration of IL- 41 and clinical presentation of patients with RA.

In this study, we developed a microfluidic device that is able to monitor cell biology under continuous PM2.5 treatment. The effects of PM2.5 on human alveolar basal epithelial cells, A549 cells, and uncovered several significant findings were investigated. The results showed that PM2.5 exposure did not lead to a notable decrease in cell viability, indicating that PM2.5 did not cause cellular injury or death. ⋯ The disruption of mitochondrial membrane potential further supports the detrimental effects of PM2.5 on A549 cells. These findings highlight several adverse effects of PM2.5 on A549 cells, including enhanced invasion and migration capabilities, altered gene expression related to ROS pathways, increased ROS production and disruption of mitochondrial membrane potential. These findings contribute to our understanding of the potential mechanisms through which PM2.5 can impact cellular function and health.

Aim: To investigate whether it is safe for patients with Omicron variant infection to undergo surgery during perioperative period. Methods: A total of 3,661 surgical patients were enrolled: 3,081 who were not infected with the Omicron variant and 580 who were infected with the Omicron variant. We conducted propensity score matching (PSM) with a ratio of 1:4 and a caliper value of 0.1 to match the infected and uninfected groups based on 13 variables. ⋯ However, there was no statistically significant difference in the incidence rate of blood transfusion, postoperative intensive care unit transfer, lung infection/pneumonia, pleural effusion, atelectasis, respiratory failure, sepsis, postoperative deep vein thrombosis, hypoalbuminemia, urinary tract infections, and medical expenses. Conclusion: Omicron infection does not significantly increase the risk of perioperative major complications. The Omicron infection may not be a sufficient risk factor to postpone elective surgery.
