Rate of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers Use and the Number of COVID-19-Confirmed Cases and Deaths.

The novel coronavirus SARS-CoV-2 uses the angiotensin-converting enzyme 2 receptor as an entry point to the cell. Cardiovascular disease (CVD) is a risk factor for COVID-19 with poor outcomes. We tested the hypothesis that the rate of angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) use is associated with the rate of COVID-19-confirmed cases and deaths.

Electrophysiological ventricular substrate of stroke: a prospective cohort study in the Atherosclerosis Risk in Communities (ARIC) study.

Objectives: The goal of the study was to determine an association of cardiac ventricular substrate with thrombotic stroke (TS), cardioembolic stroke (ES) and intracerebral haemorrhage (ICH).

Design: Prospective cohort study.

Setting: The Atherosclerosis Risk in Communities (ARIC) study in 1987-1989 enrolled adults (45-64 years), selected as a probability sample from four US communities (Minneapolis, Minnesota; Washington, Maryland; Forsyth, North Carolina; Jackson, Mississippi).

Worsening Kidney Function Is the Major Mechanism of Heart Failure in Hypertension: The ALLHAT Study.

Objectives: The authors aimed to quantify the extent to which the effect of antihypertensive drugs on incident heart failure (HF) is mediated by their effect on kidney function.

Background: The authors hypothesized that the dynamic change in kidney function is the mechanism behind differences in the rate of incident HF in ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) participants randomized to lisinopril and chlorthalidone, in comparison with those randomized to amlodipine and doxazosin.

Methods: Causal mediation analysis of ALLHAT data (1994 to 2002) included participants with available baseline and 24- to 48-month estimated glomerular filtration rate (eGFR) (N = 27,918; mean age 66 ± 7.

The Association Between the Rate of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers Use and the Number of Covid-19 Confirmed Cases and Deaths in the United States: Geospatial Study.

Background: The novel coronavirus SARS-Cov2 uses the angiotensin-converting enzyme 2 (ACE2) receptor as an entry point to the cell. Cardiovascular disease (CVD) is a risk factor for the novel coronavirus disease (Covid-19) with poor outcomes. We hypothesized that the rate of ACE inhibitor (ACEI) and angiotensin receptor blocker (ARB) use is associated with the rate of Covid-19 confirmed cases and deaths.

Bringing Critical Race Praxis Into the Study of Electrophysiological Substrate of Sudden Cardiac Death: The ARIC Study.

Background Race is an established risk factor for sudden cardiac death (SCD). We sought to determine whether the association of electrophysiological substrate with SCD varies between black and white individuals. Methods and Results Participants from the ARIC (Atherosclerosis Risk in Communities) study with analyzable ECGs (n=14 408; age, 54±6 years; 74% white) were included.

Evaluating an Indigenous health curriculum for diabetes prevention: engaging the community through talking circles and knowledge translation of results.

Background: Kahnawà:ke is a Kanien'kehá:ka (Mohawk) community in Quebec, Canada. In 1997, the community-controlled Kateri Memorial Hospital Centre in partnership with the Kahnawake Education Center, and the Kahnawake Schools Diabetes Prevention Project (KSDPP) developed an elementary school diabetes prevention health education program, aimed to increase knowledge of Type 2 diabetes, healthy eating and active lifestyles. Long-term goals for KSDPP community and school interventions are to decrease obesity and diabetes.

Response of murine bone marrow-derived mesenchymal stromal cells to dry-etched porous silicon scaffolds.

Porous silicon shows great promise as a bio-interface material due to its large surface to volume ratio, its stability in aqueous solutions and to the ability to precisely regulate its pore characteristics. In the current study, porous silicon scaffolds were fabricated from single crystalline silicon wafers by a novel xenon difluoride dry etching technique. This simplified dry etch fabrication process allows selective formation of porous silicon using a standard photoresist as mask material and eliminates the post-formation drying step typically required for the wet etching techniques, thereby reducing the risk of damaging the newly formed porous silicon.
