Accountability Assessment of Health Improvements in the United States Associated with Reduced Coal Emissions Between 2005 and 2012

Conclusions: The direct analyses of emissions reductions estimate substantial health benefits via coal power plant emission and PM2.5 concentration reductions. Differing responses associated with changes in the two exposure metrics underscore the importance of isolating source-specific impacts from those due to total PM2.5 exposure.

Publication date: Available online 21 January 2020Source: NeurocomputingAuthor(s): Emmanouil Giannakakis, Cheol E. Han, Bernd Weber, Frances Hutchings, Marcus KaiserAbstractSimulations of neural networks can be used to study the direct effect of internal or external changes on brain dynamics. However, some changes are not immediate but occur on the timescale of weeks, months, or years. Examples include effects of strokes, surgical tissue removal, or traumatic brain injury but also gradual changes during brain development. Simulating network activity over a long time, even for a small number of nodes, is a computational cha...

Using the universe of fatal car accidents in the United States from 1990 to 2015, we find that a one standard deviation reduction in daily stock market returns is associated with a 0.6% increase in fatal car accidents that happen after the stock market opening. A battery of falsification tests support a caus...

Conclusions: Mechanical thrombectomy for anterior circulation strokes based on CTP did not result in a significant functional outcome improvement. The duration of the thrombectomy procedure was the sole time-interval related to improved functional outcome. Published on 2020-01-20 12:01:10

Conclusions and discussion: Increasingly, U.S. policymakers seek to promote provider integration and coordination. Emerging evidence suggests that organizational structures, composition, and other characteristics  influence cost and quality performance. Given current efforts to reform the U.S. delivery system, future research should seek to systematically examine the role of organizational structure in cost and quality outcomes.

The objective of this study was to analyze studies on animals that had exercised prior to myocardial infarction and to examine any benefits through a systematic review and meta-analysis. The databases MEDLINE, Google Scholar, and Cochrane were consulted. We analyzed articles published between January 1978 and November 2018. From a total of 858 articles, 13 manuscripts were selected in this review. When animals exercised before experimental infarction, there was a reduction in mortality, a reduction in infarct size, improvements in cardiac function, and a better molecular balance between genes and proteins that exhibit card...

AimGuanidinoacetate N-methyltransferase (GAMT) is the second essential enzyme in creatine (Cr) biosynthesis. Short-term Cr deficiency is metabolically well tolerated as GAMT–/– mice exhibit normal exercise capacity and response to ischemic heart failure. However, we hypothesized long-term consequences of Cr deficiency and/or accumulation of the Cr precursor guanidinoacetate (GA).MethodsCardiac function and metabolic profile were studied in GAMT–/– mice>1 year.ResultsIn vivo LV catheterization revealed lower heart rate and developed pressure in aging GAMT–/– but normal lung weight and ...

ObjectivesCarotid artery geometry influences blood flow disturbances and is thus an important risk factor for carotid atherosclerosis. Extracellular matrix (ECM) and yes-associated protein (YAP) expression may play essential roles in the pathophysiology of carotid artery stenosis, but the effect of blood flow disturbances of carotid bifurcation location on the ECM is unknown. We hypothesized that carotid artery anatomy and geometry are independently associated with the ECM and YAP expression.MethodsIn this cross-sectional study, 193 patients were divided into two groups: an asymptomatic group (n = 111) and a symptomatic gr...

This study investigated the cardioprotective effect of vitexin against MIRI and its possible mechanism. Isolated SD rat hearts were subjected to MIRI in a Langendorff perfusion system, and H9c2 cells were subjected to hypoxia/reoxygenation (H/R) in vitro. Ex vivo experiments showed improved left ventricular function and reduced infarct size in the vitexin group. Transmission electron microscopy showed that I/R caused outer mitochondrial membrane rupture, cristae disappearance and vacuolation, while vitexin reduced mitochondrial damage and ultimately reduced cardiomyocyte apoptosis. In vitro, vitexin protected H9c2 cells fr...

BOSTON (CBS) — Marijuana use is growing in popularity and local doctors are sounding the alarm about the potential harms the drug could have on the heart. They say marijuana carries many of the same cardiovascular risks as smoking tobacco. Researchers at Brigham and Women’s Hospital say while more patients are curbing their use of cigarettes, there has been an acceleration in marijuana use that marijuana users are now exceeding cigarette smokers. And the effects of the drug on cardiovascular health are not fully understood. Some studies have linked marijuana use with stroke, arrhythmias, and other heart conditi...
