LcProt: Proteomics Longitudinal Cohort Study on Lung Cancer
This study will utilize tissue and peripheral blood samples for proteomics analysis and establish a longitudinal proteomics cohort at multiple critical treatment time points to explore the research value of proteomics in the diagnosis and treatment of lung cancer. The study includes key time points such as screening, postoperative efficacy …
Observational Study to Develop a Predictive Score for Adverse Events Post ERCP
The main objective of the study is: the identification of independent factors associated with an increased risk of post-ERCP complications. Other objectives are: the development of a predictive model of events post-ERCP adverse events and its validation; geographic validation of a predictive model already published in the literature using data …
Molecular Characteristics of Hepatitis B Virus Integration, Mutation, and Drug Resistance
Patients with a confirmed diagnosis of chronic hepatitis B (CHB) who have complete clinical data and retained blood or liver tissue samples will be enrolled. All patients will be grouped based on cohort sources: the Antiviral Treatment Cohort and the Cross-Sectional Epidemiological Survey Cohort. Patients in the Antiviral Treatment Cohort …
Digital Strategies to Advance Help-Seeking Aim 1 and 2
This proposal aims to establish a Digital Laboratory focused on advancing help-seeking and expediting treatment initiation in youth ages 12-29 who are at Clinical High-Risk (CHR) for developing psychosis. Leveraging the Health Action Process Approach (HAPA) model, this study will identify help-seeking subtypes in 25,000 youth who screen positive for …
SpinChip Hs-cTnI Clinical Diagnostic Performance
During a heart attack, the protein troponin I is released from the heart muscle into the bloodstream. Measurements of cardiac troponin in blood are used as an aid in the diagnosis of heart attack. The SpinChip hs-cTnI test is a new high-sensitive test for measuring the amount of cardiac troponin …
A Study on the Efficacy of Atezolizumab Combined with Chemotherapy
This is a multicenter phase III simulated RCT study aimed to compare the efficacy and safety of atezolizumab combined with chemotherapy versus placebo combined with chemotherapy in small cell lung cancer.
Familial Intrahepatic Cholestasis-related Genes Associated with Disease Susceptibility in Hepato-biliary Cancers
This is a cross-sectional, multicenter tissue study with an exploratory aim to estimate the prevalence of genetic mutations that predispose individuals to diseases in the context of cholestatic disorders and hepatobiliary neoplasms. It is intended as a hypothesis-generating study for future empirical investigations.
Effects of E-cigarette Use on Health
Electronic nicotine delivery systems (ENDS) are used by millions of Americans, however their long-term health effects are unknown. This research proposal will quantify the effects of long-term ENDS use on validated and novel biomarkers of cardiovascular and pulmonary disease and how they are influenced by use heaviness, age, body weight, …
Developing the Probability Algorithm for Pulmonary Hypertension Echocardiography
The goal of this observational study is to assess the efficacy that the addition of novel markers cardiac function, particularly of right ventricular (RV) function in echocardiography, and ECG have in detecting pulmonary hypertension. The main questions it aims to answer are: Can novel markers in ECG and echocardiography suggest …
