The availability of Sodium-glucose cotransporter-2 inhibitors (SGLT2-i) has dramatically altered the management of heart failure (HF) patients, independently of their ejection fraction and glycemic status. A meta-analysis of 57 studies comparing SGLT2-I monotherapy vs. placebo or active comparator showed reductions in major cardiovascular events, but no impact on atherothrombotic events. In fact, a non-significant increase in the risk for non-fatal stroke was observed. Similar trend observed in multiple trials indicate a SGLT2-i class effect. Sotagliflozin is the first dual SGLT1/2 receptor inhibitor, that was shown to significantly reduce atherothrombotic events compared with placebo in diabetic HF patients, suggesting that dual SGLT1/2 inhibitor may have additional properties vs. SGLT2-i. The hypothesis of this study is that dual SGLT1/2 inhibition by sotagliflozin improves thrombogenic profile (i.e. reduces thrombus formation), which could make it a safer and more effective treatment option for cardiovascular (CV) patients than SGLT2-i. To test the hypothesis, the researchers will compare the antithrombotic activity of sotagliflozin vs. empagliflozin in healthy volunteers using a randomized, cross-over study design, where each participant will receive both study treatments (sotagliflozin and empagliflozin) separated by a washout period. Treatment effects will be assessed by measuring ex vivo thrombus formation using the Badimon Perfusion chamber, platelet aggregation using Multiplate Analyzer, and Thromboelastometry using RoTEM Gamma. Study assessments will be performed before initiating (baseline/pre-treatment) and after completion of each treatment. Read Less

The Seattle Dietary Biomarker Development Center (S-DBDC) aims to advance the science of measuring dietary intake by identification and validation of dietary biomarkers that improve upon self-reported diet. To accomplish this mission, the Seattle DBDC will carry out controlled feeding studies in healthy human volunteers. Metabolomics assays will be conducted on blood and urine specimens collected during the feeding studies for biomarker identification. Stool samples will be collected and archived. Read Less

The purpose of this research study is to examine the effect of social connectedness on the brain. Study procedures include one Magnetic Resonance Imaging (MRI) or functional Magnetic Resonance Imaging (fMRI) scan, one Positron Emission Tomography (PET) scan, one Magnetic Resonance Spectroscopy (MRS) scan, an electroencephalogram (EEG), and in-person and phone call follow-ups.

The goal of this observational study is to understand how genomic and epigenetic factors contribute to resistance against chemo-immunotherapy in adults diagnosed with extensive-stage small cell lung cancer (ES-SCLC) or metastatic large cell neuroendocrine carcinoma (LCNEC). Both ES-SCLC and LCNEC are aggressive forms of lung cancer with limited treatment options and poor prognosis. While initial responses to chemo-immunotherapy are often promising, most patients develop resistance within a few months, resulting in disease progression and limited survival. This study seeks to explore the molecular and cellular changes that drive resistance, providing insights that could guide more personalized and effective treatment strategies in the future. The study focuses on identifying genomic and methylation signatures, as well as analyzing circulating tumor cells (CTCs) and tumor DNA (ctDNA), to better understand the mechanisms of resistance. By collecting and analyzing these biomarkers over time, researchers aim to identify patterns that distinguish patients who benefit long-term from therapy from those who experience early resistance. These findings may pave the way for new diagnostic tools and therapies to predict and overcome resistance to chemo-immunotherapy. The main questions this study seeks to answer are: Are there specific genomic or methylation patterns that predict resistance to chemo-immunotherapy in ES-SCLC and LCNEC? How are circulating tumor cells (CTCs) and tumor DNA (ctDNA) associated with disease progression, treatment response, and survival? What molecular differences exist between patients who respond long-term and those who develop resistance early in their treatment? Participants will: Provide blood and tumor tissue samples before treatment to establish baseline molecular profiles. Undergo follow-up visits every 9 weeks during treatment, where additional blood samples and imaging tests will be collected to monitor disease progression and treatment response. Optionally provide tissue samples through re-biopsy if the disease progresses, enabling researchers to compare changes in tumor biology over time. All blood and tissue samples will be de-identified and securely stored for genomic and epigenetic analyses. Blood samples will be examined for circulating tumor cells and tumor DNA, while tumor tissue samples will undergo in-depth genomic and methylation profiling. Researchers will use advanced molecular and bioinformatics techniques to uncover specific patterns associated with resistance, aiming to improve current treatment strategies and develop more precise therapies. The study will analyze data from patients over three years, encompassing various stages of treatment and disease progression. By examining longitudinal samples, the study aims to capture the dynamic changes that occur in the tumor microenvironment and how these relate to treatment outcomes. This research is particularly important because current treatment options for ES-SCLC and LCNEC are limited, and there are no established methods to predict which patients will respond to chemo-immunotherapy. Identifying biomarkers of resistance could transform clinical care, allowing oncologists to tailor treatments to individual patients' molecular profiles and improve survival outcomes. Ultimately, the findings from this study could lead to the development of new biomarkers for resistance, improve early detection of treatment failure, and provide the foundation for novel therapies targeting resistant cancer cells. By addressing a critical gap in the understanding of resistance mechanisms, the STRATUS trial has the potential to significantly advance the field of personalized oncology. Read Less

The purpose of this study is to assess the effect of gastric fundal mucosal ablation (GFMA) on weight trajectory following discontinuation of once-weekly semaglutide or tirzepatide in adults with obesity. In this study, GFMA will be performed on patients who have experienced \> 10% weight loss with GLP-1 therapy and who plan to discontinue use of GLP-1 medications for the duration of the study.

The research study will be conducted to obtain baseline, or "normative" information to compare an air charged HRAM catheter to traditional solid catheter measures using the IAPWG standardized testing protocol and London classification. Read Less

The goal of this observational study is to assess the reliability and validity of the 9-object MLSDT for evaluation of participants with moderate to severe vision impairment when tested without a wearable low-vision magnifying aid (eGlasses) and then with eGlasses. These results will be compared to ETDRS testing results for the same participants without eGlasses and then with eGlasses. Two cohorts will consist of participants who have vision loss due to STGD or geographic atrophy (GA) due to age-related macular degenerations (AMD). Normally sighted participants will provide a control group. Read Less
