Nonlinear Functional Models On Causal Inference, Rong Jiao

Dissertations and Theses (Open Access)

Statistical analysis has experienced significant progress on association study, but it remains elusive to understand the etiology and mechanism of complex phenotypes. As a major analytical platform, association analysis may hamper the theoretic development of biomedical science and its application. Thus, many researchers suggest making the transition from association to causation. The mainstream of research in genetics and epigenetics data analysis focuses on statistical association or exploring statistical dependence between variables. Despite significant progress in dissecting the genetic architecture of complex diseases by genome-wide association studies (GWAS), the signals identified by association analysis can only explain a small proportion of …

Uses Of Continuous-Time Markov Chain To Describe Longitudinal Patient-Reported Outcomes For Survival Prediction And Dimension Reduction, Ting-Yu Chen

Dissertations and Theses (Open Access)

A patient-reported outcome (PRO) is a type of outcome reported directly from patients, and it has been widely used in medical research and clinical trials to measure a patient’s symptoms, health-related quality of life, physical functioning, and health status. Previous studies have linked PROs to survival outcomes, but most of them only used the PRO information at baseline or at a specific clinical time point [1, 2]. Even though some of these studies collected longitudinal PROs, only few of them evaluated the association between the longitudinal PROs and a survival outcome. One of the major challenges in longitudinal PRO studies …

Hepatitis C Infection In Men Who Have Sex With Men, Jing Zhao

Dissertations and Theses (Open Access)

Hepatitis C virus (HCV) infection is the leading cause of cirrhosis, hepatocellular carcinoma, and liver transplantation. Current treatment rates and efficacy are inadequate to manage the disease burden caused by HCV; thus, efforts are needed to control HCV transmission. Besides the well-known transmission routes, which are health-care-associated transmission and transmission through injecting drugs, HCV could also be transmitted by sexual contact, especially among men having sex with men (MSM). MSM also have higher drug use prevalence than the general population, which may contribute to HCV infection by sexual disinhibition and other risky behavior. Since 2000, there have been emerging reports …

Novel Propensity Score Methods For Multiple And Continuous Treatments: Applications To Ehr Data, Derek W. Brown

Dissertations and Theses (Open Access)

Propensity scoring is often utilized to overcome the challenges posed by covariate imbalance to make causal inferences within observational studies. While methods for utilizing propensity scoring in a binary treatment case are well studied and established, generalizations to multiple unordered (multinomial) and continuous treatments are more complicated. In Aim 1, we developed and tested a novel multinomial treatment propensity score method, the GPS-CDF method, which derives a single scalar balancing score that can match and stratify subjects. Simulation results showed superior performance of the new methodology compared to standard multinomial propensity score methods. The proposed GPS-CDF method was also applied …

Efficacy Of Integrated Mental Health Care With Dual Diagnosis Patients And Their Utilization Of Psychiatric Emergency Services, Denton Scott

Doctoral Dissertations

Historically, patients with dual diagnosis have been subjected to ineffective treatment and negative attitudes from healthcare providers. Further, these patients are plagued with myriad afflictions that exist beyond substance abuse and mental illness. The treatments and collateral damage associated with the diagnosis impose excessive healthcare costs and can be of significant detriment to society. Largely, patients suffering from dual diagnosis do not receive adequate treatment. As such, psychiatric emergency services are frequently utilized as an alternate treatment, wherein the main focus of care is on the substance abuse alone. This study argues that solely treating the substance abuse is not …
