Background: To identify and analyze factors that influence the grading and zoning management model of emergency triage as a first step in the improvement of the system.
Methods: Questionnaires were used to extract data from clinical histories of 286 patients who attended the Emergency Department of Binzhou Central Hospital (Binzhou City, Shandong Province, China) from September to November of 2015. Through logistic regression analysis, influencing factors for unreasonable (≥ 2h) emergency department retention times were identified.
Results: Analysis of general characteristics of patients including gender, method of payment or assigned medical department did not result in any statistically significant differences between patients with a time to discharge longer than 2 h and those with a shorter time to discharge (P > 0.05). Older age, higher income, lower or higher education degree, admission time from 17:00-7:59, and lack of understanding of zoning management and of condition severity grading resulted in a retention time greater than or equal to 2 hours (P < 0.05). According to the Logistic regression model: age, income level, education degree, admission time, degree of understanding of zoning management and condition severity grading were all independent risk factors affecting the time to discharge from the emergency department (P <0.05).
Conclusion: Countermeasures need to be developed in order to minimize the influence of patients' factors and promote reasonable average retention times lower than 2 hours in the emergency department.

Objective: To explore the effects of veno-venous extra corporeal carbon dioxide removal (V-V ECCOR) on local mechanical power and gas distribution in the lungs of patients with mild to moderate acute respiratory distress syndrome (ARDS) receiving non-invasive ventilation.
Methods: Retrospective research methods were conducted. Sixty patients with mild to moderate ARDS complicated with renal insufficiency who were transferred to the respiratory intensive care unit (RICU) through the 96195 platform critical care transport green channel from January 2018 to January 2020 at the collaborative hospitals of Henan Provincial People's Hospital were enrolled.

Mineral precipitation is ubiquitous in natural and engineered environments, such as carbon mineralization, contaminant remediation, and oil recovery in unconventional reservoirs. The precipitation process continuously alters the medium permeability, thereby influencing fluid transport and subsequent reaction kinetics. The diversity of preferential precipitation zones controls flow and transport efficiency as well as the capacity of mineral sequestration and immobilization.

Specific yield (S) is an essential hydrogeological parameter in groundwater-related modeling and estimation. In this study, we proposed several new analytical expressions of S to characterize the nonlinear variations of S under shallow groundwater environments, encompassing S for three-layered soil, transition zone S, and flux-dependent S (in Boussinesq-type equation). The proposed S expression for three-layered soils expanded the applicability of previous expressions for homogeneous soil.

Non-grain production of cropland (NGPCL) is a common consequence of rapid urbanization, but excessive NGPCL threatens food security and sustainable cropland use. However, the evolutionary processes and mechanisms of different NGPCL types remain largely unknown, compromising the scientific basis for NGPCL management. Thus, taking rapidly urbanized Deqing as the study area, this research constructed an NGPCL theoretical framework from the perspective of agricultural location, classified NGPCL types using Landsat images, random forest algorithm and Google Earth Engine, and revealed their spatiotemporal changes and different influencing factors through the Multinomial Logit Regression model, and provided targeted zoning and categorized policy suggestions.

Background: Orbital bullet injuries resulting from high-velocity trauma pose significant clinical challenges due to the potential for severe ocular and systemic complications. This meta-analysis consolidates the existing body of knowledge on direct orbital bullet injuries with respect to clinical outcomes, management strategies, and long-term effects.
Methods: The literature search was conducted by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, using databases such as PubMed and Scopus.
