This study is testing a new way to help with migraine headaches. Researchers want to see if it's safe and doable to stimulate a blood vessel in the head (called the middle meningeal artery) with microcatheters and microwires. This has never been done before for migraines and is an investigational treatment that is not part of standard migraine treatment. This stimulation would happen just before giving the standard lidocaine treatment, which is already routinely used for migraines. The goal is to see whether this new step could help improve headache outcomes. Two FDA-cleared medical devices will be used, the Cadwell Cascade 32 PRO and the Cadwell Guardian IONM System, to perform the stimulation and monitoring. In this study, the Cascade 32 PRO will be used in a way that is not part of its usual approved purpose (this is called "off-label" use) to gently deliver electrical pulses through a microcatheter. The Cadwell Guardian IONM System will be used in its normal, FDAapproved way for continuous monitoring during stimulation.

The goal of this study is to utilize CardioMems (measurement of pulmonary artery diastolic pressure) to assess BaroStim. At the time of CardioMems insertion, patients will be screened for candidacy to receive a BaroStim device. Patients will be followed for 3 months after the CardioMems insertion before undergoing insertion of a Barostim. Patients who have undergone a CardioMems, will be eligible for enrollment after 3 months of medication management and optimization. Patients will be followed for 1 year after insertion of Barostim.

The goal of this randomized clinical trial is to determine whether a community health worker-delivered, multi-component behavioral intervention can improve antihypertensive medication adherence and blood pressure control among adult refugees with hypertension who are prescribed antihypertensive medications. The main questions it aims to answer are: 1. Does participation in the BPCARE intervention improve antihypertensive medication adherence compared to enhanced usual care? 2. Does participation in the BPCARE intervention improve blood pressure control and persistence over time compared to enhanced usual care? Researchers will compare participants randomized to the BPCARE intervention to those receiving enhanced usual care (hypertension information and a home blood pressure monitor) to determine the effects on medication adherence, blood pressure control, and persistence. Participants will: * Be randomly assigned to either the BPCARE intervention or enhanced usual care * Receive hypertension education and a home blood pressure monitor * Participate in community health worker-delivered sessions that include hypertension and medication education, motivational interviewing, problem-solving, and action planning (intervention arm only) * Complete questionnaires assessing medication adherence and related psychosocial factors * Have blood pressure monitored using connected home blood pressure devices * Complete pill counts to assess medication adherence over a nine-month follow-up period

In this study, the investigators are testing the effectiveness and implementation of the Community Health Workers (CHW)-delivered PILI Pasifika Program (PPP) Standard Facilitation or Enhanced Facilitation across 3 regions, the U.S. Affiliated Pacific Islands (USAPI), the continental U.S., and Hawai'i, among 600 Native Hawaiian and Pacific Islander (NHPI) participants in two settings, (clinical and non-clinical) over a 3-year period. The PPP is a 3-month lifestyle intervention that includes a Social Determinants of Health (SDOH) component and was NHPI-adapted from the Diabetes Prevention Program's Lifestyle Program, renamed to the PILI Lifestyle Program (PLP), which demonstrated effectiveness in improving weight, blood pressure, physical activity, and diet among NHPIs. The PPP consists of 8 lifestyle lessons and 4 SDOH activities delivered over a 3-month period. The investigators will conduct an effectiveness-implementation hybrid type 2 trial using a 3 (Region) x 2 (Setting) x 2 (Delivery Mode) factorial design. The long-term objective of this study is threefold: 1. To conduct an effectiveness-implementation hybrid 2 trial to test the effects of the PPP implementation strategies across different settings and modes of delivery among 600 NHPIs at risk for cardiometabolic-related conditions using an NHPI-approved and adapted evaluation framework. The investigators will also assess and compare the cost-effectiveness of the CHW-delivered PPP-Standard Facilitation and PPP-Enhanced Facilitation to support long-term sustainability. 2. To conduct a longitudinal Social Determinants of Health (SDOH) survey embedded within the trial to examine the reliability and validity of indices from 5 adapted SDOH instruments and to assess the associations between SDOH variables and chronic disease risk among NHPIs. 3. To implement and evaluate the contextually-based CHW training program on PPP delivery.

The goal of this clinical trial is to evaluate whether a low-glutamate diet can improve migraine symptoms in adults with migraine and to explore possible biological changes associated with dietary improvement. The study focuses on whether reducing dietary glutamate intake may influence processes involved in migraine, such as brain excitation, inflammation, and oxidative stress. The main questions this study aims to answer are: Does following a low-glutamate diet reduce the number of migraine days and the severity and duration of migraine attacks, and improve quality of life? Are improvements in migraine symptoms associated with changes in blood-based biological markers related to migraine activity? Researchers will compare participants assigned to the low-glutamate diet with participants assigned to a wait-list control group to evaluate differences in migraine outcomes and related biological measures. Participants will: Complete a baseline run-in period while tracking headaches using a daily migraine diary Either follow a low-glutamate dietary intervention or continue their usual diet as part of a wait-list control Complete standardized questionnaires related to migraine symptoms and quality of life Provide blood samples for laboratory analyses Undergo neuroimaging assessments (for a subset of participants)

The goal of this clinical trial is to treat both hypertension and obesity in adults using a food is medicine framework. Participants will be randomized 1:1 to FIM+DASH or usual-care control. The 24-week trial includes a 12-week FIM+DASH intervention followed by a 12-week maintenance period and leverages existing partnerships with community-based organizations for home food delivery and culinary skill-skill building. The main questions it aims to answer are: (1) What is the effect of FIM+DASH vs. usual care control on blood pressure? (2) What is the effect of FIM+DASH vs. usual care control on DASH diet adherence (diet quality), body weight, and waist circumference? (3) How to identify factors associated with the sustainability and scalability of FIM+DASH in real-world settings?

Atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) are very common conditions that often occur together and result in worsening symptoms and reduced quality of life (QoL). Limitations being able to participate in activities of daily living is a primary complaint for AF-HFpEF patients, yet effective strategies to address this issue remain limited. While exercise interventions targeting aerobic training (AT) are recommended for patients with AF and HFpEF, unique challenges exist in this patient population who tend to be older. Specifically, many older patients with AF and HFpEF have muscle weakness, sarcopenia and frailty, that can make aerobic-focused exercise difficult and less tolerable. This study proposes that starting with progressive resistance training (PRT) before aerobic exercise may overcome these issues by improving muscle strength, making AT more manageable, and leading to better health outcomes. The goal of this study is to assess whether a sequential exercise program, named 'PREACTIVE' improves how people feel, decrease the amount of symptoms, and their ability to participate in exercise and activities. This study will specifically test a sequenced exercise approach of resistance training followed by aerobic exercise to improve symptoms, and quality of life in AF-HFpEF.

Single-center, open label, prospective study conducted at Medstar Georgetown Headache Center. Men and woman ≥ 18 years old that are diagnosed with migraine with or without aura for at least 1 year, who report a reliable migraine trigger. Acceptable triggers for the study will include exercise, alcohol (less than one drink per day for woman and less than two drinks per day for men), air travel that lasts no more than 12 hours, sexual activity, fasting that lasts no more than 24 hours, stress or stress let-down headache.

The goal of this clinical trial is to evaluate an investigational ultralow dose positron emission tomography (PET) imaging technique for known or suspected coronary artery disease (for detecting myocardial ischemia or infarction) detection and monitoring. The main question it aims to answer is: Can the investigators optimize the timing, scan duration, and image reconstruction to reduce the radiation dose 10-100 fold of the current clinical standard? Participants will be injected with a radioactive tracer called Fluorine-18 (18F)-flurpiridaz and be imaged on a new type of high sensitivity PET scanner for up to 3 hours

This study is testing two different ways of treating atrial fibrillation (AF) in people who also have heart failure with mildly reduced or preserved heart function. Patients will randomly be assigned to either rhythm control using catheter ablation or rate control using medicines. The pilot phase will determine if a larger study can be successfully carried out to see which approach better improves survival, reduces hospitalizations, and enhances quality of life.

In patients with a myocardial infarction (MI) treated medically alone, the objective of the PANTHEON trial is to evaluate if ticagrelor monotherapy reduces bleeding events, without an increase in patient-oriented ischemic events, compared with standard dual antiplatelet therapy (DAPT) with aspirin and ticagrelor for 12 months.

The goal of this clinical trial study is to test whether a mathematical calculation, using the patient's gender, weight and kidney function, can better predict a patient's heparin goal dose than a flat number of units per patient weight can. Participants will have the first dose of heparin infusion calculated, after which if adjustments are needed, the Hospital's prebuilt table for results driven dosing for this purpose is used. The researchers will compare the time it takes for the participants to get to the desired goal using the patient's information for calculation versus patients in the past who received the medication using the flat rate. The hypothesis is that the patients with enhanced personal data, gender, weight and kidney function, included for the initial dose, will get to their goal lab value sooner and with less chance of delay or overshooting the goal. A quicker time to goal lab value is beneficial to patients in many ways, including earlier treatment of the clot or coronary issue that the patient is experiencing.
