AI Article Synopsis
- The study aimed to identify risk factors for reduction loss in patients with proximal humeral fractures treated with locking plate fixation and to create a predictive nomogram.
- Clinical data was analyzed from 115 patients treated surgically between January 2016 and December 2018, focusing on variables like age and fracture classification through univariate and multivariate analysis.
- The findings identified age, fracture type, medial comminution, and calcar screw status as key risk factors for reduction loss, and the nomogram developed showed high accuracy in predicting these risks, aiding clinicians in targeting high-risk patients for early intervention.
Article Abstract
Purpose: The purpose of our study was to determine the risk factors for reduction loss in patients with proximal humeral fractures after locking plate fixation and establish a nomogram prediction model.
Methods: We retrospectively analyzed the clinical data of proximal humeral fractures patients who had been surgically treated for locking plate in our institution from January 2016 to December 2018. Perioperative information was obtained through the electronic medial record system, univariate and multivariate analyzes were performed to determine the risk factors of reduction loss, and a nomogram model was constructed to predict the risk of reduction loss. The predictive performance and consistency of the model were evaluated by the consistency coefficient (C-index) and the calibration curve, respectively.
Results: 115 patients were finally enrolled in our study. Multivariate analysis results showed that age, fracture classification, medial comminution, and calcar screw status were independent risk factors for reduction loss. The accuracy of the contour map for predicting transfusion risk was 0.944.
Conclusion: We found a correlation between reduction loss and age, fracture classification, medial comminution, and calcar screw status after locking plate fixation for proximal humeral fractures patients. Our nomogram is helpful for clinicians to identify high-risk patients, early intervention and reduce the incidence of reduction loss.

Background: The function of some testis-specific genes (TSGs) in model insects have been studied, but their function in non-model insects remains largely unexplored. In the present study, we identified several TSGs in the fall armyworm (FAW), a significant agricultural pest, through comparative transcriptomic analysis. A testis-specific gene cluster (TSGC) comprising multiple functional genes and long non-coding RNAs was found.

Background: Use of health applications (apps) to support healthy lifestyles has intensified. Different app features may support effectiveness, including gamification defined as the use of game elements in a non-game situation. Whether health apps with gamification can impact behaviour change and cardiometabolic risk factors remains unknown.

Purpose: This study aims to investigate the possible impacts of fasting on physical activity and weight loss in adult users of glucagon-like peptide-1 (GLP-1) agonists, specifically semaglutide and tirzepatide, using qualitative methods to gain in-depth insights into participants' experiences and perceptions.
Patients And Methods: A qualitative study was conducted at the Polyclinic at King Faisal University, Al-Ahsa, Saudi Arabia, during and after Ramadan in 2024, along with the completion of International Physical Activity Questionnaires (IPAQs). The semi-structured interviews and the IPAQ were used to assess physical activity levels.
