BACKGROUND:  Ascending aorta or hemi-arch repair are common in the acute phase of type A dissection. Postdissection aneurysms can develop with antegrade perfusion of the false lumen in the dissected aortic arch and require reoperation. METHODS:  From 2012 to 2018, we reoperated nine patients with postdissection aneurysms using a hybrid technique without cardiopulmonary bypass. The patients had a EuroSCORE II of 13% and a logistic EuroSCORE I of 45% and were not candidates for frozen elephant trunk surgery...

Ischemic stroke is the leading cause of disability and death worldwide. An effective therapeutic approach is urgently needed. Stroke-induced angiogenesis and neurogenesis are essential mechanisms in the long-term repair. Extracellular matrix proteins are also involved in tissue self-repair. Recently, a PHSRN (Pro-His-Ser-Arg-Asn) peptide from the fibronectin synergistic motif that can promote wound healing in epithelia and induce endothelial proliferation and cancer cell migration was identified. The therapeutic potential of this peptide in stroke is unknown...

Traditional models of neural reorganization of language skills in patients with chronic stroke-induced aphasia (PWA) propose activation of reperfused or spared left hemisphere tissue results in the most favorable language outcomes. However, these models do not fully explain variable behavioral recovery patterns observed in chronic patients. Instead, investigation of connectivity patterns of critical network nodes may elucidate better-informed recovery models. In the present study, we combined fMRI and dynamic causal modeling (DCM) to examine effective connectivity of a simple three-node left hemisphere network during a semantic feature decision task in 25 PWA and 18 age-matched neurologically intact healthy controls...

Stachybotrys microspora triprenyl phenol (SMTP)-44D has both anti-oxidative and anti-inflammatory activities, but its efficacy has not been proved in relation to the pathological changes of neurovascular unit (NVU) and neurovascular trophic coupling (NVTC) in ischemic stroke. Here, the present study was designed to assess the efficacies of SMTP-44D, moreover, compared with the standard neuroprotective reagent edaravone in ischemic brains. ICR mice were subjected to transient middle cerebral artery occlusion (tMCAO) for 60 min, SMTP-44D (10 mg/kg) or edaravone (3 mg/kg) was intravenously administrated through subclavian vein just after the reperfusion, and these mice were examined at 1, 3, and 7 d after reperfusion...

Hemorrhagic transformation after ischemic stroke is an independent predictor for poor outcome and is characterized by blood vessel rupture leading to brain edema. To date, no therapies for preventing hemorrhagic transformation exist. Disintegrins from the venom of Crotalus atrox have targets within the coagulation cascade, including receptors on platelets. We hypothesized that disintegrins from C. atrox venom can attenuate hemorrhagic transformation by preventing activation of matrix metalloproteinase after middle cerebral artery occlusion (MCAO) in hyperglycemic rats...

OBJECTIVES: Preference weights derived from general population samples are often used for therapeutic decision making. In contrast, patients with cardiovascular disease may have different preferences concerning the benefits and risks of anticoagulant therapy. Using a discrete choice experiment, we compared preferences for anticoagulant treatment outcomes between the general population and patients with cardiovascular disease. METHODS: A sample of the general US population and a sample of patients with cardiovascular disease were selected from online panels...

OBJECTIVE: Whether migraine modifies after spontaneous cervical artery dissection (sCeAD) more than after other stroke etiologic subtypes has never been adequately investigated. METHODS: In the setting of the Italian Project on Stroke in Young Adults (IPSYS), we compared the course of migraine before and after acute brain infarct in a group of migraine patients with sCeAD and a group of migraine patients whose ischemia was due to a cause other than CeAD (non-CeAD IS), matched by sex, age (± 3 years), and migraine subtype...

This study investigated the acoustic features of vowel production in Mandarin-speaking patients with post-stroke dysarthria (PSD). The subjects included 31 native Mandarin-speaking patients with PSD (age: 25-83 years old) and 38 neurologically normal adults in a similar age range (age: 21-76 years old). Each subject was recorded producing a list of Mandarin monosyllables that included six monophthong vowels (i.e., /a, i, u, ɤ, y, o/) embedded in the /CV/ context. The patients' speech samples were evaluated by two native Mandarin speakers...

Omecamtiv mecarbil (OM) is a positive cardiac inotrope in phase-3 clinical trials for treatment of heart failure. Although initially described as a direct myosin activator, subsequent studies are at odds with this description and do not explain OM-mediated increases in cardiac performance. Here we show, via single-molecule, biophysical experiments on cardiac myosin, that OM suppresses myosin's working stroke and prolongs actomyosin attachment 5-fold, which explains inhibitory actions of the drug observed in vitro...

Computed tomography (CT) is used to diagnose many emergent medical conditions, including stroke and traumatic brain injuries. Unfortunately, the size, weight, and expense of CT systems make them largely inaccessible for patients outside of major hospitals. We have designed a module containing multiple miniature x-ray sources that could allow for CT systems to be significantly lighter, smaller, and cheaper, and to operate without any moving parts. We have developed a novel photocathode-based x-ray source, created by depositing a thin film of magnesium on an electron multiplier...

PURPOSE: Edaravone is a free-radical scavenger. Edaravone 30mg IV has been approved for use in the treatment of acute ischemic stroke in Japan and China, and for amyotrophic lateral sclerosis in Japan and the United States. Considering the inconvenience of IV infusion in clinical practice, an oral tablet formulation of edaravone was developed but failed in 2011 due to poor bioavailability. More recently, a sublingual (SL) tablet formulation of edaravone 30mg was developed by a Good Manufacturing Practices-compliant manufacturer in China...
