Improving Remote Breathalyzer Procedures Used by Clinicians and Researchers to Remotely Monitor Alcohol Use
Remote breath alcohol monitors have been increasingly adopted for use in clinical, research and forensic settings to monitor alcohol use because they offer several key advantages over other available monitoring methods. However, it remains unknown if remote breathalyzers reliably detect alcohol use because there is up to a 10-hour window …
Respiratory and Hemodynamic Implications of Endoscopic Myotomy of the Esophagus and Stomach
The goal of this observational study is to learn about hemodynamic and respiratory repercussions during general anesthesia in patients with achalasia or gastroparesis who underwent an endoscopic treatment such as a peroral endoscopic myotomy (POEM) or gastric (GPOEM). The main questions it aims to answer are: Are there predictable elements …
Contrast-Enhanced Mammography for the Evaluation of Mammographic Microcalcifications
This clinical trial evaluates the added role of contrast-enhanced mammography (CEM), as well as imaging and blood biomarkers, for predicting the presence or absence of high-grade ductal carcinoma in situ (DCIS) or invasive cancer on pathology. Screening mammography is the mainstay of population-wide early breast cancer detection, and mammography-detected cancers …
Identification of New Biomarkers for Patients With Cholangiocarcinoma and Gallbladder Cancer
No validated biomarkers exist that can identify patients with biliary tract cancer at an early stage or predict treatment outcomes. The objective of the present study is to find diagnostic, prognostic and predictive biomarkers.
Characterizing Disease Biology, Treatment and Toxicity in Older Adults With Hepatocellular Carcinoma
This is an observational, prospective cohort study that will recruit a diverse sample of 84 participants with newly diagnosed with unresectable, advanced hepatocellular carcinoma (HCC) at the UT Health Cancer Center in San Antonio. This study uses geriatric assessment tools with participants 65 years and older and collects adverse events …
A Registry of Subjects With Primary Indeterminate Lesions or Choroidal Melanoma
The purpose of this observational research study is to follow participants who have been treated with either bel-sar or received alternate treatment (sham, standard of care therapy, etc.) while participating in a previous Aura Biosciences clinical research study to assess the long-term safety and effectiveness in these subjects. This study …
The Effect of Chronic Stress on Efficacy of ICIs in Esophageal Cancer Patients (STRESS-ESCA Study)
Chronic stress refers to a special emotional state caused by unexpected stress for a long time, with an increasing incidence in the population. It can cause the body to release hormones such as cortisol and adrenaline. Tumor patients often experience changes such as psychological and emotional abnormalities, decreased quality of …
Multidimensional Phenotyping Towards Personalized Preventive Nutritional Support for Elderly People
There is high inter-individual variability in the response to feeding, which is determined by multiple interacting factors such as age, sex, genotype, gut microbiota, eating behaviors, physical activity or even socio-demographic factors. Original studies have recently demonstrated the possibility of predicting the postprandial response to the diet of healthy individuals …
Physical Activity, Cardiac and Skeletal Muscle Energetics in Healthy Subjects and HFpEF Patients
This research is being done to better understand the relationship between information collected by wearable devices and clinical measurements in people with heart failure with preserved ejection fraction (HFpEF) and others without HFpEF. This is an observational study with no study intervention or randomization. Participants will undergo baseline history and …
