Summary: This study introduces a Bayesian approach to develop a random effects model for site-level CLA and binary tooth presence/absence status. The model uses a spatial skew-normal/independent distribution for random effects, with a conditionally autoregressive structure. The benefits of this approach are highlighted through simulation studies and application to actual clinical data on periodontal disease status.

Summary: The study aimed to evaluate pre- and in-hospital mortality for moderate-to-severe TBI in the U.S. by injury type and estimate annual regression-adjusted mortality from 2008-2014. The results showed a decreasing trend in in-hospital mortality for both blunt and penetrating trauma patients in the late period compared to the early period, while prehospital mortality significantly increased.

Summary: The study found that a high proportion of elderly trauma patients were admitted due to ground-level falls, with the incidence of falls increasing with age and plateauing after 85 years old. Although overall mortality rates decreased over time, there was an increase in adverse discharge disposition and loss of functional independence, particularly among patients admitted to non-level I trauma centers.

Summary: This study investigated the incidence, clinical associations, and risk factors for missed compartment syndrome after surgical stabilization of tibia shaft fractures. Male gender was identified as the most significant risk factor for missed diagnosis of compartment syndrome, followed by alcoholism, penetrating trauma, and smoking. Open fracture was found to be a significant protective factor. These findings can help physicians identify at-risk patients and potentially prevent the high morbidity associated with missed compartment syndrome.

Summary: The study showed that geriatric skiers experienced higher seriousness of injuries, higher rates of facility care at discharge, and higher mortality compared to non-geriatric skiers. Specialized care is needed for geriatric ski trauma with high impact.

Summary: Clustered competing risks data with informative cluster size (ICS) and missing causes of failure are commonly encountered in multicenter studies. We propose a semiparametric marginal proportional cause-specific hazards model and a maximum partial pseudolikelihood estimator to address this problem. The proposed method allows for ICS and auxiliary variables related to the probability of missingness, and its asymptotic properties are rigorously established. Simulation studies demonstrate its superior performance compared to methods that ignore within-cluster dependence and ICS.

Summary: Clustered competing risks data are common in multicenter studies, and analyzing such data is often complicated due to informative cluster size and missing causes of failure. This study proposes a new method, using a semiparametric marginal proportional cause-specific hazards model and a maximum partial pseudolikelihood estimator, to address these challenges.

Summary: The National Children's Study Archive (NCSA) was established as a repository for samples, data, and information to provide qualified researchers with access for secondary research. The NCSA model offers a 3-tiered access system designed to allow users to explore and request data and samples at different levels.

Summary: This study investigated the nationwide epidemiology of traumatic cerebrospinal fluid (CSF) leaks and analyzed the clinical characteristics and surgical management of patients. The results showed that most patients were young adult males, and motor vehicle accidents were the common mechanism of injury. The majority of patients were discharged within 2 weeks.

Summary: Capital surcharges on GSIBs reduce lending to firms without any real effects. Banks subject to higher surcharges decrease loan commitments and estimates of firm risk, but firms' total borrowing does not decline as they switch to other banks. The study contributes to the debate on the costs and benefits of surcharges and regulatory tailoring, and their effects on credit supply reallocation across financial institutions.

Summary: The study introduces a mixture factor analysis method for estimating missing values in building electric load data. Due to quality issues in building electric load data, a novel data imputation model is proposed to represent patterns and their cyclic rotations, providing better handling of missing data problems and improving efficiency and accuracy in model selection.

Summary: Using data feminism, this study examines the National Agricultural Statistics Service Quick Stats database, revealing the unstated assumptions in data collection, aggregation, and dissemination practices. These assumptions prioritize certain agricultural topics while neglecting others crucial for contemporary sustainability. The study argues that this perpetuates an inequitable and unsustainable food systems status quo and suggests recommendations for data providers and users based on reflexivity, context, and pluralism.

Summary: This study demonstrated the application of generalized hypothesis testing using a linear mixed effects model to detect change points, with two rarely used contrasts found to be best suited for detection of potential change points. The applicability of these methods for real experimental data was shown through simulation studies and in-vivo data from a preclinical study.

Summary: This study investigates the role of protective behavioral strategies (PBS) in the association between perceived discrimination and alcohol-related problems among Hispanic college students. The findings suggest that greater perceived discrimination is associated with more frequent alcohol use and more alcohol-related problems, while greater use of PBS is associated with fewer alcohol-related problems. Additionally, serious harm-reduction behaviors moderate the association between perceived discrimination and alcohol-related problems, providing protection for Hispanic college students against the negative effects of perceived discrimination.

Summary: This study examines the impact of the percentage of heavy drinkers and abstainers in one's social network on the effectiveness of brief alcohol interventions among trauma patients. The results suggest that interventions may be most effective when patients do not have heavy drinkers in their social networks.

Summary: This study examines the relationship between motivations for responsible drinking and the use of alcohol protective behavioral strategies among college students. Findings suggest that greater psychological need satisfaction and dispositional autonomy are related to more self-determined motivations for responsible drinking, which in turn are associated with more frequent use of protective behavioral strategies. The study highlights the importance of understanding and promoting responsible drinking behaviors among college students through autonomous motivations.

Summary: The study found that the Readiness to Change Questionnaire (RCQ) demonstrated measurement invariance across biological sex and intervention conditions, but only partial invariance across race/ethnicity and alcohol use severity. Hispanic and Black participants scored higher on contemplation and action in the RCQ, while White participants scored lower on these dimensions.

Summary: The study found initial support for the utility of both motivation for drinking and drinking responsibly in explaining alcohol use and its consequences among college students. Autonomous motivations for drinking responsibly were negatively correlated with drinking motives, indicating a potential protective effect. Drinking motives were identified as risk factors for alcohol-related problems.
