The goal of this observational study is to determine if a pharmacist-led program involving continuous glucose monitoring (CGM) improves glucose control and health behavior in people with prediabetes. The main questions it aims to answer are: 1. Determine impact of pharmacist-led CGM on glycemic control in people with prediabetes. Researchers will compare change in hemoglobin A1c at 12 weeks with pharmacist-led CGM versus a historical cohort of subjects with prediabetes receiving no CGM. We will also assess change in CGM-derived glycemic metrics from baseline to end of the CGM wear period in the intervention group. 2. Evaluate impact of pharmacist-led CGM on health behavior change in people with prediabetes in the intervention group. Participants will be asked to complete the Summary of Diabetes Self-Care Activities Measure (SDSCA) and 36-Item Short Form Health Survey (SF-36) at baseline, at the end of week 4, and at the end of the study so that researchers can measure the effects in the intervention group on health behavior change.

Every fetus has a small hole in their heart, called a foramen ovale when they are developing in the womb. For most people this hole closes shortly after birth, but it doesn't close completely in 1 out of every 4 people. This is called a "patent" foramen ovale, or PFO. In people with a PFO it is possible for a blood clot in a vein to enter the heart, pass through the opening, and then go into an artery - this is referred to as a paradoxical embolism which passes through a "Right-to-Left Shunt," or RLS. If this occurs, the blood clot can cause a stroke. The most common RLS (more than 90%) is a PFO. Much rarer causes include other types of holes in the heart (like an atrial septal defect, or ASD), or a vascular communication in the lungs (like a pulmonary arteriovenous malformation, or AVM). We are investigating whether people with a PE are at higher risk of stroke if they happen to have an RLS compared to PE patients who don't have an RLS. This study will simply observe and compare the differences in stroke-related outcomes between those 2 groups. Participation in the study last roughly 90-days and includes the following activities: - The study team will review your medical records to collect general information such as your age, sex, race/ethnicity, height, weight, medications, medical history, and other medical information - Magnetic Resonance Imaging (MRI) of your brain will be done as soon as possible following your enrollment in the study. For more information on MRI scans, please see the "MRI scan" section below. - A Transcranial Doppler (TCD) with bubble study will be performed to determine if an opening is present in your heart or lungs. TCD is performed using ultrasound. A contrast called agitated saline will be injected into your vein for this test. - You will be asked to return for a follow-up visit 90 days after your pulmonary embolism. At this visit, the following will occur: 1. A second MRI of your brain will be performed. 2. You will complete a questionnaire to evaluate whether you may have had a stroke since being discharged from the hospital 3. You will meet with a member of the study team who will collect information about your health status.

The goal of this observational study is to learn whether results from a brief exercise test done before surgery can help identify adults who may be more likely to have problems after moderate- to high-risk noncardiac surgery. The study includes adults older than 45 years who are seen in a pre-surgical evaluation clinic and complete submaximal cardiopulmonary exercise testing, or smCPET, as part of their usual clinical care. The main questions it aims to answer are: Are smCPET measurements linked with early problems after surgery? Are smCPET measurements linked with later problems after surgery, including complications within 30 and 60 days, longer hospital stay, and death? Can smCPET add useful information to standard preoperative risk assessment? Researchers will observe and analyze information collected during routine care. No extra exercise testing or treatment will be done for research. Participants will: - Complete routine preoperative evaluation in the Yale Pre-Surgical Evaluation Clinic. - Undergo smCPET if it is ordered as part of standard clinical care. - Allow researchers to collect information from the medical record and from the exercise test for the study repository, if they agree to participate. The study will collect de-identified information about each participant's health before surgery, exercise test results, details about the surgery and hospital stay, and problems that happen after surgery. This may include age, sex, body mass index, other medical conditions, routine lab and imaging results, heart rate, blood pressure, oxygen levels, smCPET measures such as peak oxygen uptake, anaerobic threshold, and breathing efficiency, and early and late postoperative outcomes. Researchers will look at short-term and later outcomes after surgery. These include problems identified during the hospital stay, such as heart, lung, kidney, nerve, blood, wound, and pain-related complications, as well as complications within 30 and 60 days after surgery. Researchers will also study hospital length of stay and death after surgery. This study is designed to help researchers understand whether a short, practical exercise test can improve the way surgical risk is assessed before an operation. Current preoperative assessment tools do not always measure how well the heart, lungs, and muscles work together during physical stress. smCPET may provide a more objective way to measure functional capacity and physiologic reserve in a busy clinic setting. This is a single-center study based in a preoperative evaluation clinic. The study has a prospective observational cohort component and a retrospective validation component. In the prospective part, adults who meet clinic criteria and complete smCPET during routine care may be asked to join the repository. In the retrospective part, researchers may also review historical data from patients evaluated before smCPET was put into routine use to help compare outcomes and validate findings. Because this is an observational repository study, participation does not change the care participants receive. The exercise test is done for clinical reasons, not because of the research study. The research team will not assign treatments or decide what surgery a participant has. Instead, the team will study how exercise test findings relate to outcomes that occur after surgery. The long-term aim of this study is to improve preoperative risk assessment and help clinicians better identify patients who may need closer monitoring, more evaluation, or more support around the time of surgery. If the findings are useful, they may support broader use of brief preoperative exercise testing in adults having higher-risk noncardiac surgery.

This research study is being conducted to find out more about techniques to non-invasively evaluate liver disease. This is the second phase of a project in which we are testing a new technology to evaluate the liver (LiverScope®). We will compare LiverScope® to other methods to evaluate the liver, including advanced conventional liver MR exams. MR exams are common exams used to monitor MASLD (also known as NAFLD). Conventional MR scanners use magnetic fields and radio waves to make pictures of the liver. LiverScope® is a small, portable MR-based device that uses similar, but simplified technology, and can be used on top of an exam table in an outpatient setting. LiverScope® currently is not approved for clinical use. In this second phase of the study, we took what we learned in the first phase to optimize the LiverScope® device and are now testing to see how LiverScope® measurements compare to MR after these optimizations. Study participants will be asked to complete a one-time visit which includes: - LiverScope exam - MR exam - FibroScan exam (optional) - Blood draw - Completion of study questionnaires
