Long-Term Outcomes of Mechanical Thrombectomy for Stroke: A Meta-Analysis.
Authors: McCarthy DJ, Diaz A, Sheinberg DL, Snelling B, Luther EM, Chen SH, Yavagal DR, Peterson EC, Starke RM
Abstract
Mechanical thrombectomy (MT) has become the standard treatment for large vessel occlusion (LVO) in acute ischemic stroke (AIS). Few studies have investigated long-term outcomes for AIS treated with MT. Therefore, a pooled meta-analysis using data from randomized clinical trials (RCT) was performed to assess for long-term clinical outcomes. A systematic literature search was conducted on 27 September 2017, by searching the English literature in the Cochrane Library, MEDLINE, and Embase for RCTs inv...

Mystery of why arteries harden may have been solved, say scientists
Study finds calcium deposits are triggered by molecule produced by damaged cellsThe mysterious mechanism behind the hardening of arteries may have been solved, researchers have revealed, in a study that also suggests the first potential preventive drug for the condition linked to heart attack, dementia and stroke.Arteries harden as calcium becomes deposited in the elastic walls of the vessels, a process that happens as we age and is exacerbated for patients with diabetes or kidney disease. Stiffening can also occur as calcium becomes deposited in fatty plaques in the arteries – a condition called atherosclerosis.Continue reading...

Up to 25 cups of coffee a day safe for heart health, study finds
High consumption of coffee no worse for arteries than drinking less than a cup a dayCoffee lovers who drink up to 25 cups a day can rest assured the drink is not bad for their heart, scientists say.Some previous studies have suggested that coffee stiffens arteries, putting pressure on the heart and increasing the likelihood of a heart attack or stroke, with drinkers warned to cut down their consumption.Continue reading...

Heavily processed food like ready meals and ice-cream linked to early death
Two major studies add to body of evidence against foods made with industrial ingredientsPeople who eat large amounts of heavily processed foods, from breakfast cereals and ready meals to muffins and ice-cream, have a greater risk of heart attack, stroke and early death, according to two major studies.The findings, from separate teams in France and Spain, add to a growing body of evidence that foods made in factories with industrial ingredients may have a hand in an array of medical disorders such as cancer, obesity and high blood pressure.Continue reading...

Adrenergic receptor antagonism induces neuroprotection and facilitates recovery from acute ischemic stroke Neuroscience
Spontaneous waves of cortical spreading depolarization (CSD) are induced in the setting of acute focal ischemia. CSD is linked to a sharp increase of extracellular K+ that induces a long-lasting suppression of neural activity. Furthermore, CSD induces secondary irreversible damage in the ischemic brain, suggesting that K+ homeostasis might constitute...

PGE2 signaling via the neuronal EP2 receptor increases injury in a model of cerebral ischemia Medical Sciences
The inflammatory prostaglandin E2 (PGE2) EP2 receptor is a master suppressor of beneficial microglial function, and myeloid EP2 signaling ablation reduces pathology in models of inflammatory neurodegeneration. Here, we investigated the role of PGE2 EP2 signaling in a model of stroke in which the initial cerebral ischemic event is followed...

Luke Perry and John Singleton remind us that strokes can strike younger adults too
Sudden weakness on one side of the body. Slurred speech. Loss of vision. Trouble with balance. Severe headaches.These are signs of a stroke. If it happened to someone close to you, would you know what to do?After the age of 55, the risk of a stroke doubles every decade, but younger people can...

Roles of hyaluronan in cardiovascular and nervous system disorders.
Abstract
Hyaluronan is a widely occurring extracellular matrix molecule, which is not only a supporting structural component, but also an active regulator of cellular functions. The chemophysical and biological properties of hyaluronan are greatly affected by its molecular size and several hyaluronan-binding proteins, making hyaluronan a fascinating molecule with great functional diversity. This review summarizes our current understanding of the roles of hyaluronan in cardiovascular and nervous system disorders, such as atherosclerosis, myocardial infarction, and stroke, with the aim to provide a foundation for fu...

PAC, an evolutionarily conserved membrane protein, is a proton-activated chloride channel
Severe local acidosis causes tissue damage and pain, and is one of the hallmarks of many diseases including ischemia, cancer, and inflammation. However, the molecular mechanisms of the cellular response to acid are not fully understood. We performed an unbiased RNA interference screen and identified PAC (TMEM206) as being essential for the widely observed proton-activated Cl– (PAC) currents (ICl,H). Overexpression of human PAC in PAC knockout cells generated ICl,H with the same characteristics as the endogenous ones. Zebrafish PAC encodes a PAC channel with distinct properties. Knockout of mouse Pac abolished ICl,H i...

Scientists Restore Some Brain Activity in Recently Slaughtered Pigs
(NEW YORK) — Scientists restored some activity within the brains of pigs that had been slaughtered hours before, raising hopes for some medical advances and questions about the definition of death.
The brains could not think or sense anything, researchers stressed. By medical standards “this is not a living brain,” said Nenad Sestan of the Yale School of Medicine, one of the researchers reporting the results Wednesday in the journal Nature.
But the work revealed a surprising degree of resilience among cells within a brain that has lost its supply of blood and oxygen, he said.
“Cell death in the brai...

Even low alcohol consumption is bad news for strokes – study
Moderate drinking of one or two glasses a day does not protect against stroke, say researchersA low level of alcohol consumption does not protect against stroke, new research suggests, in the latest blow to the idea that a few drinks can be beneficial to health.At least100,000 people have strokes in the UK every year, according to recent figures. It had been thought that low levels of alcohol consumption might have a protective effect against stroke, as well as other diseases and conditions. Now researchers say that in the case of stroke, even low levels of alcohol consumption are bad news.Continue reading...
