Mechanical Circulatory Support in Patients Without Cardiogenic Shock Undergoing Percutaneous Coronary Intervention.

Background: The use of mechanical circulatory support devices for high-risk percutaneous coronary intervention (PCI) has increased over the past decade despite limited data of benefit. We sought to examine the association between intravascular microaxial left ventricular assist device (LVAD) versus intra-aortic balloon pump use in patients without cardiogenic shock (CS) undergoing PCI.

Methods And Results: This retrospective study analyzed claims data from a large, insured population who underwent PCI without CS from April 1, 2016 to July 31, 2022.

The association between hypertensive disorders during pregnancy and maternal and neonatal outcomes: a retrospective claims analysis.

Background: Hypertensive disorders during pregnancy continue to increase in prevalence and are associated with several adverse outcomes and future cardiovascular risk for mothers. This study evaluated the association of hypertensive disorders compared to no hypertension during pregnancy with neonatal and maternal outcomes. We then evaluated risk factors associated with progression from a less to more severe hypertensive disorder during pregnancy.

Clinical Outcomes and Cost Associated With an Intravascular Microaxial Left Ventricular Assist Device vs Intra-aortic Balloon Pump in Patients Presenting With Acute Myocardial Infarction Complicated by Cardiogenic Shock.

Importance: Intravascular microaxial left ventricular assist device (LVAD) compared with intra-aortic balloon pump (IABP) has been associated with increased risk of mortality and bleeding among patients with acute myocardial infarction (AMI) and cardiogenic shock (CS) undergoing percutaneous coronary intervention (PCI). However, evidence on the association of device therapy with a broader array of clinical outcomes, including data on long-term outcomes and cost, is limited.

Objective: To examine the association between intravascular LVAD or IABP use and clinical outcomes and cost in patients with AMI complicated by CS.

Doula care across the maternity care continuum and impact on maternal health: Evaluation of doula programs across three states using propensity score matching.

Background: This evaluation of doula care emerges at a time when maternal mortality in the U.S. outranks every country in the developed world.

Counting on U training to enhance trusting relationships and mental health literacy among business advisors: protocol for a randomised controlled trial.

Background: Financial distress is thought to be a key reason why small-medium enterprise (SME) owners experience higher levels of mental health conditions compared with the broader population. Business advisors who form trusting, high-quality relationships with their SME clients, are therefore well placed to: (1) help prevent/reduce key sources of financial distress, (2) better understand the business and personal needs of their clients and, (3) recognise the signs and symptoms of mental health conditions and encourage help-seeking where appropriate. The aim of this study is to compare the effectiveness of relationship building training (RBT) combined with mental health first aid (MHFA) training for business advisors with MHFA alone, on the financial and mental health of their SME-owner clients.

Race and Gender Differences in the Association Between Experiences of Everyday Discrimination and Arterial Stiffness Among Patients With Coronary Heart Disease.

Background: Self-reported experiences of discrimination have been linked to indices of cardiovascular disease. However, most studies have focused on healthy populations. Thus, we examined the association between experiences of everyday discrimination and arterial stiffness among patients with a history of myocardial infarction (MI).

Self-assembled multivalent (SAMul) ligand systems with enhanced stability in the presence of human serum.

Self-assembled cationic micelles are an attractive platform for binding biologically-relevant polyanions such as heparin. This has potential applications in coagulation control, where a synthetic heparin rescue agent could be a useful replacement for protamine, which is in current clinical use. However, micelles can have low stability in human serum and unacceptable toxicity profiles.

Activation of Aflatoxin Biosynthesis Alleviates Total ROS in Aspergillus parasiticus.

An aspect of mycotoxin biosynthesis that remains unclear is its relationship with the cellular management of reactive oxygen species (ROS). Here we conduct a comparative study of the total ROS production in the wild-type strain (SU-1) of the plant pathogen and aflatoxin producer, , and its mutant strain, AFS10, in which the aflatoxin biosynthesis pathway is blocked by disruption of its pathway regulator, . We show that SU-1 demonstrates a significantly faster decrease in total ROS than AFS10 between 24 h to 48 h, a time window within which aflatoxin synthesis is activated and reaches peak levels in SU-1.

Evaluating different criteria for defining a complete ambulatory blood pressure monitoring recording: data from the Jackson Heart Study.

Objective: We determined differences in the prevalence of blood pressure (BP) phenotypes and the association of these phenotypes with left ventricular hypertrophy (LVH) for individuals who fulfilled and did not fulfill various criteria used for defining a complete ambulatory blood pressure monitoring (ABPM) recording.

Methods: We analyzed data for 1141 participants from the Jackson Heart Study. Criteria evaluated included having greater than or equal to 80% of planned readings with more than or equal to one reading per hour (Spanish ABPM Registry criteria), more than or equal to 70% of planned readings with a minimum of 20 daytime and seven nighttime readings (2013 European Society of Hypertension criteria), greater than or equal to 14 daytime and greater than or equal to seven nighttime readings (2003 European Society of Hypertension criteria), more than or equal to 10 daytime and more than or equal to 5 nighttime readings (International Database of Ambulatory Blood Pressure in Relation to Cardiovascular Outcome criteria), and greater than or equal to 14 daytime readings (UK National Institute of Health and Clinical Excellence criteria).

Chronic kidney disease and incident apparent treatment-resistant hypertension among blacks: Data from the Jackson Heart Study.

It is unclear whether black patients with chronic kidney disease (CKD) vs those without CKD who take antihypertensive medication have an increased risk for apparent treatment-resistant hypertension (aTRH). The authors analyzed 1741 Jackson Heart Study participants without aTRH taking antihypertensive medication at baseline. aTRH was defined as uncontrolled blood pressure while taking three antihypertensive medication classes or taking four or more antihypertensive medication classes, regardless of blood pressure level.

Cardiovascular Health and Incident Hypertension in Blacks: JHS (The Jackson Heart Study).

Several modifiable health behaviors and health factors that comprise the Life's Simple 7-a cardiovascular health metric-have been associated with hypertension risk. We determined the association between cardiovascular health and incident hypertension in JHS (the Jackson Heart Study)-a cohort of blacks. We analyzed participants without hypertension or cardiovascular disease at baseline (2000-2004) who attended ≥1 follow-up visit in 2005 to 2008 or 2009 to 2012 (n=1878).

Blood Pressure, Antihypertensive Polypharmacy, Frailty, and Risk for Serious Fall Injuries Among Older Treated Adults With Hypertension.

Antihypertensive medication and low systolic blood pressure (BP) and diastolic BP have been associated with an increased falls risk in some studies. Many older adults have indicators of frailty, which may increase their risk for falls. We contrasted the association of systolic BP, diastolic BP, number of antihypertensive medication classes taken, and indicators of frailty with risk for serious fall injuries among 5236 REGARDS study (Reasons for Geographic and Racial Difference in Stroke) participants ≥65 years taking antihypertensive medication at baseline with Medicare fee-for-service coverage.

Morphological control of self-assembled multivalent (SAMul) heparin binding in highly competitive media.

Tuning molecular structures of self-assembling multivalent (SAMul) dendritic cationic lipopeptides controls the self-assembled morphology. In buffer, spherical micelles formed by higher generation systems bind polyanionic heparin better than worm-like micelles formed by lower generation systems. In human serum, the binding of spherical micelles to heparin is adversely affected, while worm-like micelles maintain their relative binding ability.

Cardiovascular Risk Factors and Masked Hypertension: The Jackson Heart Study.

Masked hypertension is associated with increased risk for cardiovascular disease. Identifying modifiable risk factors for masked hypertension could provide approaches to reduce its prevalence. Life's Simple 7 is a measure of cardiovascular health developed by the American Heart Association that includes body mass index, physical activity, diet, cigarette smoking, blood pressure (BP), cholesterol, and glucose.

Ambulatory blood pressure monitoring phenotypes among individuals with and without diabetes taking antihypertensive medication: the Jackson Heart Study.

Ambulatory blood pressure monitoring (ABPM) can detect phenotypes associated with increased cardiovascular disease (CVD) risk. Diabetes is associated with increased CVD risk but few data are available documenting whether blood pressure (BP) phenotypes, detected by ABPM, differ between individuals with versus without diabetes. We conducted a cross-sectional analysis of 567 participants in the Jackson Heart Study, a population-based study of African Americans, taking antihypertensive medication to evaluate the association between diabetes and ABPM phenotypes.

Association of Reduced eGFR and Albuminuria with Serious Fall Injuries among Older Adults.

Background And Objectives: Falls are common and associated with adverse outcomes in patients on dialysis. Limited data are available in earlier stages of CKD.

Design, Setting, Participants, & Measurements: We analyzed data from 8744 Reasons for Geographic and Racial Differences in Stroke Study participants ≥65 years old with Medicare fee for service coverage.

Ambulatory Blood Pressure Monitoring in Individuals with HIV: A Systematic Review and Meta-Analysis.

Introduction: Abnormal diurnal blood pressure (BP) rhythms may contribute to the high cardiovascular disease risk in HIV-positive (HIV+) individuals. To synthesize the current literature on ambulatory BP monitoring (ABPM) in HIV+ individuals, a systematic literature review and meta-analysis were performed.

Methods: Medical databases were searched through November 11, 2015 for studies that reported ABPM results in HIV+ individuals.

Heparin versus DNA: Chiral Preferences in Polyanion Binding to Self-Assembled Multivalent (SAMul) Nanostructures.

This communication presents simple cationic self-assembling multivalent (SAMul) first generation dendrons based on L or D lysine, which form identical nanoscale assemblies in terms of dimensions and charge densities but toward which DNA and heparin exhibit different chiral binding preferences. However, higher generation dendrons with larger hydrophilic head groups are bound identically by these polyanions, irrespective of chirality. We propose that well-organized chiral ligands on the surface of self-assembled nanostructures can exhibit enantioselective polyanion binding.

Association of systolic blood pressure levels with cardiovascular events and all-cause mortality among older adults taking antihypertensive medication.

Introduction: The aim of the study was to identify the association of systolic blood pressure (SBP) levels with cardiovascular events, all-cause mortality, and falls among elderly persons taking antihypertensive medication.

Methods: US adults ≥ 45 years of age taking antihypertensive medication enrolled in the REGARDS study were categorized into 3 age groups: 55-64, 65-74 and ≥ 75 years old and baseline on-treatment SBP levels. Our primary analyses focused on incident cardiovascular disease (CVD) (n=9787) and all-cause mortality (n=13,948).

Shape-persistent and adaptive multivalency: rigid transgeden (TGD) and flexible PAMAM dendrimers for heparin binding.

This study investigates transgeden (TGD) dendrimers (polyamidoamine (PAMAM)-type dendrimers modified with rigid polyphenylenevinylene (PPV) cores) and compares their heparin-binding ability with commercially available PAMAM dendrimers. Although the peripheral ligands are near-identical between the two dendrimer families, their heparin binding is very different. At low generation (G1), TGD outperforms PAMAM, but at higher generation (G2 and G3), the PAMAMs are better.

Injury risk among children in motor vehicle crashes: older versus younger drivers.

Aim: To explore the relationship between injury risk among child occupants involved in motor vehicle collisions according to the age of the vehicle driver.
