Clinical and Molecular Characteristics of Primary Aldosteronism in Blacks

Background: The adrenal gland makes the hormone aldosterone. This helps regulate blood pressure. An adrenal gland tumor that makes too much aldosterone can cause high blood pressure and low potassium. The cause of these tumors is unknown, but sometimes they are inherited. Objective: To study the genes that may cause primary aldosteronism in Black individuals. Eligibility: People ages 18-70 who: Are Black, African American, or of Caribbean descent And have difficult to control blood pressure or primary aldosteronism Relatives of people with primary aldosteronism Design: Participants who are relatives of people with primary aldosteronism will have only 1 visit, with medical history and blood tests. Participants with primary aldosteronism or difficult to control blood pressure (suspected to possibly have primary aldosteronism) will be screened with a 1-2 hour visit. If they qualify, they will return for a hospital stay for 7-10 days. Tests may include: Medical history Physical exam Blood tests: Participants will have a small tube (IV catheter) inserted in a vein in the arm. They may drink a glucose-containing liquid or get a salt solution. If medically indicated, they may have invasive blood tests with a separate consent. Urine tests: Some require a high-salt diet for 3 days. Heart tests Scans: Participants lie in a machine that takes pictures of the body. A dye may be injected through a vein. Small hair sample taken from near the scalp. Kidney ultrasound Bone density scan: Participants lie on a table while a camera passes over the body. If the doctors feel it is medically necessary, they will offer participants treatment depending on their results. These treatments may cure the patient of their disease and may include: 1. Having one adrenal gland removed by the Endocrine surgeon under anesthesia. Patients will have follow-up visits 2-4 weeks after surgery. 2. Taking drugs to block the effects of aldosterone Participants may return about 1 year later to repeat testing.

Genetics of Type 2 Diabetes in West Africans

Background: * Type 2 diabetes (T2D) and associated complications are major contributors to the global disease burden. T2D is already a major health threat in populations in developed countries and is rapidly taking hold in the developing world. * It is believed that understanding the complex interplay between genetic and lifestyle characteristics in the etiology of T2D and related complications will lead to the development of better preventive and therapeutic strategies. In Addition, the results of this project will facilitate our understanding of causes of diabetes in African Americans, other US and world populations Objectives: * To conduct a genome-wide association study (GWAS) to identify susceptibility genetic variants for diabetes among the Yoruba people in Ibadan, Nigeria. * To enroll and examine 300 unrelated cases of T2D and 300 ethnicity-matched Yoruba controls. * To conduct resequencing of positional candidate gene/loci to identify likely functional variants in a subset of the cohort. * To conduct replication studies of the top-100 scoring variants in three independent African and European ancestry samples. * To investigate whether diabetes-associated variants discovered in European populations increase diabetes risk in West Africans. Eligibility: * Patients 18 years of age with confirmed T2D who are newly diagnosed or on treatment of Yoruba ethnicity in Ibadan, Nigeria. Control subjects are nondiabetics ethnically matched to patients. Design: * The study design for both patients and controls consists of the following steps: * Discuss informed consent process and obtain signed informed consent form. Informed consent will be administered by trained clinic staff. * Assign study ID (barcode) * Administer questionnaires * Obtain spot urine sample * Measure blood pressure * Obtain anthropometric measurements including body composition * Perform finger prick for blood glucose level * Obtain venous blood samples * Perform eye examination * On the following day, perform confirmatory blood glucose for the small subset of participants requiring confirmation of previous test result DNA extraction of stored samples will be done at either the National Institutes of Health or the laboratory in Nigeria. * GWAS will be conducted using publicly available software packages.

EASi-PROTKT™ - A Study to Test Vicadrostat (BI 690517) Taken Together With Empagliflozin in People With Type 2 Diabetes, High Blood Pressure, and Cardiovascular Disease

This study is open to adults with type 2 diabetes, high blood pressure, and cardiovascular disease. People can join the study if they have these conditions and do not have a history of heart failure. The purpose of this study is to find out if a medicine called vicadrostat, when taken with empagliflozin, helps reduce cardiovascular risk in people with these conditions. The study will compare this combination to a placebo version of vicadrostat with empagliflozin. Participants are put into 2 groups randomly, which means by chance. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets with empagliflozin. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take a tablet once per day for 2 and a half years and up to 4 years and 3 months. All participants also continue their medication for type 2 diabetes, high blood pressure, and cardiovascular disease. Participants have an equal chance of receiving the study medicine or placebo. Participants are in the study for up to 4 years and 3 months. During this time, they visit the study site regularly. During these visits, doctors collect information about participants' health and take blood samples. The doctors document when participants experience cardiovascular events. The doctors also regularly check participants' health and take note of any unwanted effects.

Genomics, Environmental Factors and Social Determinants of Cardiovascular Disease in African-Americans Study (GENE-FORECAST)

Our objective is to develop a community-based cohort and novel genomic science resource for defining the biological significance of ancestry-related genomic variation in African-Americans within the GENE-FORECAST :GENomics, Environmental FactORs and the Social DEterminants of Cardiovascular Disease in African Americans STudy. AIM I. examine the associations between common or ancestry-related DNA variants and CVD risk factors (e.g. hypertension) and phenotypes (e.g. coronary artery calcification) in African-Americans (AA).AIM II. To examine the associations between health behaviors or social-environmental factors and CVD risk factors and phenotypes in AA.The study is designed to create a cohort amenable to nested case-control analyses based on a community-based sampling frame with a target size of approximately 1800 self-identified, US -born, African-American (AA) men and women (ages 21-65) to be recruited over the next 5-6 years from the metropolitan Washington DC, Montgomery County (MC) and Prince George s County (PG) areas to be recruited to the NIH Clinical Center. The initial participant recruitment two approaches: 1) a random-digit telephone screening survey targeting study-eligible AA that will be consented and invited to an evaluation visit in the NIH Clinical Center which we contracted with a well-established survey group (Southern Research Group \[SRG\]); and 2) a community outreach effort to recruit participants into the Clinical Center by leveraging marketing and the engagement of community-based leaders, organizations and faith-based institutions in the area. this approach will yield a sample with normal individuals as well as a high proportion of AA with CVD risk factors such as obesity and hypertension that predispose to the eventual clinical signs and symptoms of CVD (e.g. heart attack and stroke). it is anticipated that the prevalence of clinically manifest CVD (history of angina, heart attack or stroke) will be less than 10-15% of the sample. All will medical evaluation (e.g. anthropometrics, blood pressure), laboratory tests (e.g. lipid levels, kidney function), social determinants profiles (e.g. socioeconomic status (SES), perceived stress, discrimination, depression, perceived neighborhood characteristics), blood/urine collection for deep-sequencing based omic analyses (e.g. whole exome sequencing, and RNA-Seq), as well as testing for pre-clinical , biomarkers of the pathobiological processes of CVD or CVD phenotypes (e.g. coronary artery calcification, microalbuminuria, leukocyte telomeres, or vascular dysfunction). It is anticipated that these deep sequencing efforts will yield novel ancestry-related DNA variants associated with the CVD phenotypes; yet with unclear biological significance in elucidating racial disparities in CVD. Accordingly, our protocol also includes a Genotype-to-Phenotype (G2P) component that re- contacts subsets of the cohort based on their genotype (e.g. APOL1 chronic kidney disease risk alleles) for a call-back visit for more in-depth phenotyping and characterization of the potential effect of the DNA variant of interest on human systems biology. In some cases family members of the proband may also be invited to participate in these G2P studies to further characterize the biological significance of these putative functional DNA variants of interest. The primary outcome variables involve well established CVD phenotypes: 1) CVD risk factors (e.g. hypertension, dyslipidemia), 2) markers of pre-clinical CVD (i.e. coronary artery calcification, coronary plaque burden by cardiac CT angiography (CTA), carotid plaque burden by 3D ultrasound, vascular dysfunction, microalbuminuria, C-reactive protein, Vitamin D levels). The protocol will assess exposures associated with CVD and relevant covariates including: 1) social determinants (e.g. socioeconomic status (SES), perceived stress, discrimination, and depression); 2) environmental factors such as neighborhood characteristics (geospatial features of healthy lifestyles \[e.g. walkability\]) and 3) behavioral factors (e.g. diet, physical activity). The G2P callback visit protocol will involve additional measures of in-depth phenotyping that include: 1) peripheral immune cell phenotyping (e.g. T-cell, monocyte subsets); 2) blood/immune cell RNAseq; 3) iPSC cell line generation (endothelial; vascular smooth muscle cells) and analysis of cardiovascular cell systems biology; 4) HDL proteome analysis, 5) FDG PET/CT and/or PET/MRI scan (vascular inflammation) 6) echocardiography, 7) bisulfite sequencing for identifying sites of DNA methylation, and 8) chromatin immunoprecipitation followed by sequencing (Chip-Seq) for identifying sites of histone modification. It is anticipated that this multi-level, multi-dimensional analysis of genomic and phenotypic characteristics of AA will advance our understanding of the bio-social determinants of the intragroup variance and the increased overall burde...

Addressing HyperteNsion and Diabetes Through Community-Engaged Systems in Puno, Peru (ANDES Study)

Hypertension (HTN) has become the largest driver of morbidity and mortality (M\&M) worldwide, affecting nearly 1 billion persons, the vast majority living in low- and middle-income countries (LMICs). While clinical research has identified highly-efficacious and inexpensive options to control HTN, rates of awareness, treatment and control of HTN are abysmally low. Implementation strategies that can effectively reach and engage patient populations while feasible within the constraints of frail health systems are urgently needed. In Peru, less than 10% of those with HTN are optimally controlled and thus avoidable M\&M continues to increase at unacceptable levels. In the proposed ANDES strategy, ANDES research team will study a vulnerable, impoverished indigenous Andean population that has a high prevalence of HTN (18.5%) and Type 2 Diabetes (T2D) (7.4%); living at high altitude. The study has two phases: UG3/UH3. During the formative UG3 phase (ended 12/31/22) we completed 3 aims, including: a) adapting community-based service delivery models for detection/control of HTN/T2D using stakeholder-engaged approaches; and b) assessed short-term implementation and service outcomes of pilot Health Fairs to detect HTN/T2D and a CHW-led model for engagement and treatment of HTN/T2D in two communities. A number of stakeholder in-depth interviews revealed significant limitations to HTN control. Discrete Choice Experiments (DCEs) surveys helped understand attributes for a community health worker (CHW)-led HTN care program that patients would value. Human-Centered Design was used to refine CHWs manual prototype, frequency and content of training sessions on patients, training CHW, supervision and integration into the healthcare system; facility-based health worker training content and approaches; identified opportunities for CHWs to improve health care system by helping to promote hypertension diagnosis, treatment and control. All these activities were used to refine the protocol that was tested in the pilot study where 1,079 subjects underwent blood pressure monitoring under a Standard Operating Procedure using electronic tablets to construct a REDCap database. The UH3 phase will test the adapted ANDES strategy. ANDES is a two-arm, individually randomized superiority trial with parallel assignment. The overall objective of ANDES is to evaluate the effectiveness of a home-based Health Agent-led intervention in reducing blood pressure and improving diabetes control in patients from under-resourced communities in Puno, Peru. Potential ANDES study participants will be identified, screened, and recruited via 2 different mechanisms: 1) community health fairs and 2) healthcare facility-based enrollment. Health fair planning, will be conducted in collaboration with DIRESA \& EsSalud and local healthcare facility leaders. All health fair attendees will be screened for blood pressure measurements. ANDES research study staff will do screening at tents in the health facilities after doctors refer patients (or for any patients to visit who want) to inquire about their willingness for an in-person screening visit at their home. Recruitment will be rolling over 24 months during which 1068 participants in total (534 participants per arm) will be enrolled. To detect a difference in systolic blood pressure of 2.5 mmHg between intervention and control arms with 95% confidence, 90% power and a standard deviation of 12 mmHg, ANDES research team would need 485 participants per arm. Assuming a conservative lost-to-follow-up of 10% at 12 months, ANDES research team would need to randomize 1068 participants in total (534 participants per arm). The primary outcome is to determine if the ANDES intervention impacts SBP in comparison to the usual care arm 12 months after randomization. ANDES participants will initiate one of two care pathways according to the randomization assignment. Participants in the usual care group will be referred to their local healthcare facility for evaluation and/or to receive medical therapy per typical standard of care and at the discretion of the treating physician for the entirety of the ANDES study. Participants in the ANDES intervention group will receive the ANDES implementation package consisting of health agent home visits for 12 consecutive months. Implementation package delivery will end after month 12, at which time intervention participants will be advised to obtain standard care from their local healthcare facility. Study outcome measures will be obtained in both the usual care and ANDES intervention group at months 12 and 18 post-randomization. All participants will receive visits at baseline, 12 and 18 months for study outcome assessments. Intervention participants will additionally receive a total of 12 visits by health agents as part of the intervention package, for a total of 18 visits for those assigned to the intervention group.

Childhood-Onset Essential Hypertension Natural History Study

Background: Childhood-onset essential hypertension (COEH) is high blood pressure that develops in children and teens. High blood pressure is a major risk factor for heart disease. COEH is more likely to be caused by changes in genes rather than by factors like stress or diet. Researchers want to learn more about how changes in genes relate to COEH. They hope to use that information to develop better treatments for children with high blood pressure. Objective: This natural history study will look for genes and gene changes that may lead to COEH. Eligibility: People aged 2 years and older with COEH or who had COEH when they were children. Healthy relatives of those with COEH are also needed. Design: Participants will have one clinic visit per year for up to 10 years. All participants will have a physical exam. They will provide samples of blood and urine. At their first visit, they will have a swab (like a Q-tip) rubbed between their gums and cheeks. They may agree to having a skin biopsy; a piece of skin about the size of a pencil eraser will be removed. Affected participants aged 2 to 17 years old will have additional tests: * They will have sensors placed on their skin to look at their blood vessels and see how blood is moving in their bodies. * They will lie or stand while a machine measures the amount of fat and muscle in their bodies. * They will have an ultrasound; a wand will be rubbed against their skin to take pictures of their kidneys. Other things are optional for all participants: * They may have photographs taken of their bodies. * They may have tests of their heart function. * They may have different types of imaging scans....

Evaluating the Navajo Community Outreach and Patient Empowerment (COPE) Program

Since 2009, a programmatic community-based strategy (COPE) has been implemented to address health disparities among Navajo individuals living with multiple chronic conditions. COPE (Community Outreach and Patient Empowerment) targets individual, family, and health system-level factors through four activities: 1) coordination between community health representatives (CHRs) and Indian Health Service providers; 2) CHR competency with standardized training; 3) a culturally-sensitive health promotion curriculum for patients and families; and 4) strong CHR supervision. COPE has been implemented throughout Navajo Nation. Enrollment is programmatic; in other words, the decision to enroll a patient in COPE occurs independently of whether the patient is in this study. Participants receive the COPE intervention in the same manner and intensity, whether they are included in this observational study or not. The main goal of this observational research is to understand if COPE improves the lives of participating community members. The Primary Aim is to assess the impact of the COPE Project on changes in HbA1c and other CVD risk factors. Hypothesis: Patients enrolled in the COPE program will experience a reduction in HbA1c compared to the control group. Secondary aims are: 1) To understand if COPE improves patients' own self-reported outcomes. Hypothesis: COPE patients will report better health compared with their own baseline at 12 months. 2) To Identify factors associated with increased effectiveness of the COPE Project at the individual, community, and health system level using a mixed-model approach. 3) To understand diverse stakeholder perspectives on COPE impact and value among CHRs, providers and the health care system. Hypothesis: Compared with baseline, CHRs will report greater empowerment in their work, providers will report greater confidence in CHRs. The observational cohort will be comprised of individuals with diabetes receiving care at one of the participating health facilities. Cases include individuals participating in the COPE intervention; controls are non-COPE participants identified within the same hospital and matched based on similar baseline characteristics. Study findings will improve clinical and patient-decision making and the health of marginalized AI/ANs by informing policies to promote CHR interventions in rural and underserved communities.

Exercise Impact in Elderly With Multimorbidity: HbA1c and Blood Pressure

The main objective of the study is to compare the effect of two different types of physical exercise modalities on glycated hemoglobin and blood pressure in elderly individuals with multimorbidity. The main characteristic of the proposal is that it is experimental, with two intervention groups with physical exercise that will be randomized in the order of participation of the groups and forwarded to the researchers regarding the evaluations and training periods. In addition, the study will be controlled, as it has a control group that will not perform any intervention with physical exercises during the study period. To allocate the participants in each exercise group and for the control group, the researchers will use the 1:1 method, the user will receive an automatic generator through the random.org website. The main questions raised by the studies will be: Is land-based training more effective than aquatic training for this population in improving the primary outcomes? Is there a difference between training at these intensities and not doing any physical exercise in this population with these primary outcomes? Participants in the 2 intervention groups will: Train 3x per week for 10 weeks at intensities that will progress over the weeks.

The Influence of Tai Chi Practice on Blood Pressure and Brain Health Among Older Adults With Hypertension (ACTION)

High blood pressure and poor cognitive function are two common health problems among older adults in the United States. They are also closely related because high blood pressure may lead to negative changes in brain structure and function such as poor brain blood flow that can cause poor cognitive function. Executive function is one type of cognitive function that let people plan and perform difficult tasks. It is commonly damaged by high blood pressure. It is also very important for older adults because they need good executive function to live on their own. Tai Chi is a good exercise option for older adults because it is safe, fun, and social. Research studies show that Tai Chi can reduce blood pressure and improve cognitive function, especially executive function. However, researchers do know if these heart and brain health benefits of Tai Chi are connected. In the ACTION study, researchers will first measure how a single session of Tai Chi followed by a 12-week online Tai Chi program with easy movements changes blood pressure and cognitive function, focusing on executive function. Then, researchers will test if these changes in heart and brain health are connected, and if they are connected through the changes in brain structure and function. Both the single session and 12-week online Tai Chi program will be practiced by a group of older adults with high blood pressure and normal cognitive function. They will be new to Tai Chi and not exercising regularly. The hypotheses of the ACTION study are that practicing Tai Chi is good for the heart and brain of older adults with high blood pressure. Specifically, relaxing Tai Chi with gentle movements will reduce blood pressure, and thereby improve cognitive function, particularly executive function.

Conical Forearm and Cylindrical Upper Arm Non-Invasive Blood Pressure (NIBP) Measurements in Pregnant Patients

The diagnosis of hypertensive disease during pregnancy is predicated on strict blood pressure thresholds: 140/90 on at least two occasions measured four hours apart for both gestational hypertension and preeclampsia. An improvement in diagnostic accuracy of even 5mm Hg would be significant, as reflected by the US Association for the Advancement of Medical Instrumentation (AAMI), the British Hypertension Society, the European Society of Hypertension (ESH) Working Group on Blood Pressure (BP) Monitoring, and the International Organization for Standardization (ISO)consensus for validation of non-invasive blood pressure (NIBP) devices during pregnancy. Given the known inaccuracies of upper arm cylindrical cuff measurements in morbidly obese patients, a conical cuff which provides more accurate measurements will translate into direct patient benefit via more informed diagnosis and management. Fewer women may be exposed to unnecessary treatment, preterm delivery, and/or cesarean section. Recognizing the increasing prevalence of morbid obesity and hypertensive disease amongst pregnant women in the United States, the identification of a more accurate non-invasive cuff is desperately needed. Increasing the accuracy of NIBP measurements on Labor and Delivery has the potential to directly impact the management of tens of thousands of morbidly obese pregnant women diagnosed with hypertensive disease in the United States every year. Establishing the level of agreement between conical forearm and cylindrical upper arm cuffs will shed light on the presence and magnitude of any disparity between measurement methods. STUDY ENDPOINTS: Primary Outcome Measures: * Agreement between conical and cylindrical cuff systolic blood pressure across groups * Agreement between conical and cylindrical cuff diastolic blood pressure across groups Secondary Outcome Measures: • Agreement between conical and cylindrical cuff mean arterial pressure

Effects of Different Forms of a Natural Heart Hormone on Blood Pressure and Fluid Balance in Healthy Volunteers

The human heart produces hormones that help regulate blood pressure and fluid balance in the body. One of these hormones is atrial natriuretic peptide (ANP). ANP lowers blood pressure by relaxing blood vessels and increasing urinary excretion by the kidneys. Previous research has demonstrated that ANP naturally carries a small sugar molecule attached. This sugar moiety is produced endogenously and can modify the biological activity of ANP. When this sugar is present, ANP may affect blood vessels and renal function differently compared with the non-glycosylated form. The present study examines how this sugar modification alters the physiological effects of ANP. This is achieved by administering ANP, either with or without the attached sugar molecule, via intravenous infusion. The study aims to determine whether glycosylated ANP differs from the native form in its effects on blood pressure and fluid balance.

The study team wants to see if using virtual reality (VR) can help with stress of Black women. The investigator will look at things like sleep, stress, and how well the VR works. The investigator also wants to know about any problems Black women might have using virtual reality.

Social Needs Screening and Chronic Diseases Study (WE CARE)

The goal of this clinical trial is to learn if the implementation of the WE CARE social determinants of health (SDOH) screening and referral intervention with an antiracist lens in primary care settings can lead to a meaningful decrease in chronic disease by monitoring conditions such as hypertension, diabetes, depression, hyperlipidemia, and asthma through clinical measures. The main question it aims to answer is: Does the WE CARE SDOH screening and referral intervention applying an antiracism lens informed implementation strategies have the potential to reduce racial/ethnic health inequities in chronic diseases for minoritized patients?
