Ca2+ signaling, particularly the mechanism via store-operated Ca2+ entry (SOCE) and receptor-operated Ca2+ entry (ROCE), plays a critical role in the development of acute hypoxia-induced pulmonary vasoconstriction and chronic hypoxia-induced pulmonary hypertension. This study aimed to test the hypothesis that chronic hypoxia differentially regulates the expression of proteins that mediate SOCE and ROCE (STIM, Orai, and TRPC6) in pulmonary (PASMC) and coronary (CASMC) artery smooth muscle cells. The resting cytosolic [Ca2+] ([Ca2+]cyt) and the stored [Ca2+] in the sarcoplasmic reticulum (SR) were not different in CASMC and PASMC...

PROBLEM/CONDITION: Preconception health is a broad term that encompasses the overall health of nonpregnant women during their reproductive years (defined here as aged 18-44 years). Improvement of both birth outcomes and the woman's health occurs when preconception health is optimized. Improving preconception health before and between pregnancies is critical for reducing maternal and infant mortality and pregnancy-related complications. The National Preconception Health and Health Care Initiative's Surveillance and Research work group suggests ten prioritized indicators that states can use to monitor programs or activities for improving the preconception health status of women of reproductive age...

BACKGROUND: Despite effective antiviral treatment, hundreds of kidneys from deceased donors with hepatitis C virus (HCV) are discarded annually. Little is known about the determinants of willingness to accept HCV-infected kidneys among HCV-negative patients. METHODS: At 2 centers, 189 patients undergoing initial or reevaluation for transplant made 12 hypothetical decisions about accepting HCV-infected kidneys in which we systematically varied expected HCV cure rate, allograft quality and wait-time for an uninfected kidney...

BACKGROUND: Cardiovascular diseases (CVDs) are the leading cause of non-communicable disease deaths globally, with hypertension being a major risk factor contributing to CVDs. Blood pressure is a heritable trait, with relatively few genetic studies having been performed in Africans. This study aimed to identify genetic variants associated with variance in systolic (SBP) and diastolic (DBP) blood pressure in black South Africans. METHODS: Genotyping was performed using the Metabochip in a subset of participants (mixed sex; median age 17...

Marinobufagenin (MBG) is an endogenous steroidal α1-Na+K+-ATPase inhibitor. Because of its role in sodium handling, MBG has been associated with both antihypertensive and prohypertensive effects in normal physiology and pathology. MBG is positively associated with blood pressure in Dahl salt-sensitive rats exhibiting a similar hypertensive phenotype to black populations, characterized by impaired urinary Na+ excretion. However, clinical studies exploring blood pressure (BP)-related effects of MBG in black populations are scant...

OBJECTIVE: To assess the relationships between self-reported psychosocial stress and preterm birth, hypertensive disease of pregnancy, and small-for-gestational-age (SGA) birth and to assess the extent to which these relationships account for racial and ethnic disparities in these adverse outcomes. METHODS: Self-reported measures of psychosocial stress (perceived stress, depression, racism, anxiety, resilience, and social support) were collected during pregnancy among a racially and ethnically diverse cohort of women enrolled in a prospective observational study of nulliparous women with singleton pregnancies, from eight clinical sites across the United States, between October 2010 and May 2014...

Low birthweight (LBW) remains a significant public health problem in Pakistan and further understanding of factors associated with LBW is required. We conducted a hospital-based matched case control study to identify risk factors associated with LBW in a rural district of Pakistan. We found that illiteracy (AOR: 2.68; 95% CI: 1.59 - 4.38), nulliparity (AOR: 1.82; 95% CI: 1.26-2.44), having a previous miscarriage/abortion (AOR: 1.22; 95% CI: 1.06-2.35), having < 2 antenatal care (ANC) visits during last pregnancy (AOR: 2...

Measure Accurately, Act Rapidly, and Partner With Patients (MAP) is an evidence-based protocol implemented to improve hypertension control in a clinic for underserved patients (49.9% Medicaid and 50.2% black). Patients with hypertension seen during the year before intervention and with at least one visit during the 6-month intervention (N = 714) were included. If initial attended blood pressure (BP; standard aneroid manometer) was ≥140/≥90 mm Hg, unattended automated office BP was measured in triplicate and averaged (Measure Accurately) using an Omron HEM-907XL...

BACKGROUND: Healthcare systems use population health management programs to improve the quality of cardiovascular disease care. Adding a dedicated population health coordinator (PHC) who identifies and reaches out to patients not meeting cardiovascular care goals to these programs may help reduce disparities in cardiovascular care. OBJECTIVE: To determine whether a program that used PHCs decreased racial/ethnic disparities in LDL cholesterol and blood pressure (BP) control...

BACKGROUND: There is extensive evidence that pre-pregnancy chronic hypertension is associated with high risk of development of severe hypertension and preeclampsia and birth of small for gestational age neonates. However, previous studies have not reported whether anti-hypertensive use, blood pressure control or normalization of blood pressure during early pregnancy influence the rates of these pregnancy complications. OBJECTIVE: To stratify women with pre-pregnancy chronic hypertension according to the use of antihypertensive medications and level of blood pressure control at the first hospital visit during the first-trimester of pregnancy and examine the rates of severe hypertension, preeclampsia and birth of small for gestational age neonates according to such stratification...

BACKGROUND: Although sudden cardiac death is a leading cause of death in the United States, most victims of sudden cardiac death are not identified as at-risk prior to death. We sought to derive and validate a population-based risk score that predicts sudden cardiac death. METHODS: The Atherosclerosis Risk in Communities (ARIC) Study recorded clinical measures from men and women aged 45-64 at baseline; 11,335 white and 3,780 black participants were included in this analysis...

OBJECTIVES: Plasma renin activity (PRA) and aldosterone tend to differ between Blacks and Caucasians and studies are very scarce among Africans. We therefore aimed to determine the normative value of plasma renin activity and serum aldosterone among school teachers in Nigeria with normal blood pressure compared with their hypertensive counterparts and relevant clinical/demographic associations. METHODS: Plasma renin activity and serum aldosterone were measured using the kits provided by Diagnostic Biochem, Canada among randomly selected school teachers recruited as part of a study to assess their total cardiovascular risks...

In the United States (U.S.), Blacks have higher morbidity and mortality from cardiovascular disease (CVD) than other racial groups. The Black racial group includes African Americans (AAs), African immigrants (AIs), and Afro-Caribbeans (ACs); however, little research examines how social determinants differentially influence CVD risk factors in each ethnic subgroup. We analyzed the 2010-2014 National Health Interview Survey, a cross-sectional, nationally representative survey of non-institutionalized civilians...

A growing body of research from the United States informed by intersectionality theory indicates that racial identity, gender, and income are often entwined with one another as determinants of health in unexpectedly complex ways. Research of this kind from Canada is scarce, however. Using data pooled from ten cycles (2001-2013) of the Canadian Community Health Survey, we regressed hypertension (HT) and diabetes (DM) on income in subsamples of Black women (n = 3,506), White women (n = 336,341), Black men (n = 2,806) and White men (n = 271,260)...

BACKGROUND: Statin therapy is highly efficacious in the prevention of fatal and nonfatal atherosclerotic events in persons at increased cardiovascular risk. However, its long-term effectiveness in practice depends on a high level of medication adherence by patients. METHODS: We identified nondiabetic adults with cardiovascular risk factors between 2008 and 2010 within a large integrated health care delivery system in Northern California. Through 2013, we examined the use and adherence of newly initiated statin therapy based on data from dispensed prescriptions from outpatient pharmacy databases...
