Sherif M Reda, Murali Chandra
Recent clinical studies have revealed a new hypertrophic cardiomyopathy-associated mutation (F87L) in the central region of human cardiac troponin T (TnT). However, despite its implication in several incidences of sudden cardiac death in young and old adults, whether F87L is associated with cardiac contractile dysfunction is unknown. Because the central region of TnT is important for modulating the muscle length-mediated recruitment of new force-bearing cross-bridges (XBs), we hypothesize that the F87L mutation causes molecular changes that are linked to the length-dependent activation of cardiac myofilaments...

Stroke induces complex and dynamic, local and systemic changes including inflammatory reactions, immune responses, and repair and recovery processes. Mesenchymal stem cells (MSCs) have been shown to enhance neurological recovery after stroke. We hypothesized that serum factors play a critical role in the activation of bone marrow (BM) MSCs after stroke such as by increasing proliferation, paracrine effects, and rejuvenation. Human MSCs (hMSCs) were grown in fetal bovine serum (FBS), normal healthy control serum (NS), or stroke patient serum (SS)...

Neurological complications of infective endocarditis are frequent, especially ischaemic strokes. As intravenous thrombolysis in infective endocarditis-related ischaemic stroke has a controversial benefit/risk ratio, alternative treatment regimens have to be considered. We present the case of a young patient with septic embolism of the middle cerebral artery who was successfully treated with mechanical thrombectomy, and give a short review of the existing literature.

Background Retrospective data indicate increased stroke incidence in Aboriginal/Torres Strait Islander (Indigenous) Australians, possibly with poorer outcomes. We present the first prospective population-based stroke incidence study in Indigenous Australians. Methods We pooled data from ASCEND and SEARCH, two prospective "ideal" South Australian stroke incidence studies, ASCEND conducted in urban Northwestern Adelaide (2009-2010) and SEARCH in five South Australian rural centers (2009-2011). We calculated age-standardized incidence for Aboriginal and non-Aboriginal people...

Infections in adult ventricular assist device patients increase subsequent mortality and stroke risk. Less is known about outcomes after infections in younger patients, where diabetes and obesity, risk factors associated with poor outcomes, are less prevalent. The purpose of this study was to examine outcomes after infections in adolescents and young adults with continuous-flow left ventricular assist devices (VAD) bridged to transplant. From Pediatric Interagency Registry for Mechanically Assisted Circulatory Support and Interagency Registry for Mechanical Circulatory Support registries, we identified patients aged 12-29 years with continuous-flow VADs implanted as bridged to transplant from September 2012 to March 2016...

The peripheral immune system plays a critical role in aging and in the response to brain injury. Emerging data suggest inflammatory responses are exacerbated in older animals following ischemic stroke; however, our understanding of these age-related changes is poor. In this work, we demonstrate marked differences in the composition of circulating and infiltrating leukocytes recruited to the ischemic brain of old male mice after stroke compared to young male mice. Blood neutrophilia and neutrophil invasion into the brain were increased in aged animals...

Background: Patients with polycystic kidney disease (PKD) might have a risk of cardiovascular diseases because several cardiovascular risk factors are occasionally associated with PKD patients. Data on the association between PKD and the risk of cardiovascular events, including acute coronary syndrome (ACS), stroke, and congestive heart failure (CHF), are scant. Methods: Patients aged ≥20 years who were newly diagnosed with PKD (International Classification of Diseases, Ninth Revision, Clinical Modification codes 753...

Stroke is the second most common cause of death worldwide, and thus, it imposes great financial burdens on both individuals and society. Mesenchymal stem cell (MSC) therapy is a promising approach for ischemic brain injury. However, MSC treatment potential is progressively reduced with age, limiting their therapeutic efficacy for brain repair post‑stroke. C1q and tumor necrosis factor‑related protein 9 (CTRP9) is a novel cytoprotective cytokine with antioxidant effects, which is highly expressed in brain tissue...

PURPOSE: The present study aimed to evaluate the efficacy and safety of polymer-free drug-coated BioFreedom stent implantation in comparison to coronary artery bypass graft (CABG) before major noncardiac surgery. MATERIALS AND METHODS: In a multicenter registry, 55 patients required revascularization before major noncardiac surgery that should not be delayed >6 months. Of them, 27 underwent BioFreedom stent implantation and 28 underwent CABG. Primary outcomes included rate of noncardiac surgery, time from revascularization to noncardiac surgery, and occurrence of composite outcomes (all-cause death, myocardial infarction, stent thrombosis, stroke, repeat revascularization, or major bleeding)...

Modern ischaemic stroke management involves intravenous thrombolysis followed by mechanical thrombectomy, which allows markedly higher rates of recanalization and penumbral salvage than thrombolysis alone. However, <50% of treated patients eventually enjoy independent life. It is therefore important to identify complementary therapeutic targets. In rodent models, the salvaged penumbra is consistently affected by selective neuronal loss, which may hinder recovery by interfering with plastic processes, as well as by microglial activation, which may exacerbate neuronal death...

Dissection of the internal carotid artery (ICA) accounts for 5% to 25% of ischemic strokes in young adults. We report a case of spontaneous recanalization of a traumatic ICA dissection in which carotid duplex (CDU) and transcranial color-coded duplex ultrasound (TCCD) were used. A 47-year-old male presented with intermittent episodes of headache, blurry vision, anisocoria, and loss of taste sensation following a whiplash injury while body surfing. Magnetic resonance angiogram (MRA) of the neck revealed absent flow in the cavernous ICA and a clot at the skull base...

Background: As there was no evidence of long-term studies on stroke trend, stroke subtypes and its relationships to stroke risk factors and demographic characteristics in Iran, we aimed to evaluate the 10-year trend of stroke incidence and stroke subtypes in Isfahan, Iran. Methods: In a hospital-based retrospective study, 24186 cases with the first-ever stroke were analyzed. We assessed the incidence trend of annual stroke and its subtypes [ischemic stroke (IS) subarachnoid hemorrhage (SAH), and intracranial hemorrhage (ICH)] during the years 2003 to 2013 by sex, and studied the association of demographic and major stroke risk factors with incidence and mortality rate of stroke...

Dabigatran etexilate (DE), a new oral anti-coagulant, is a direct thrombin inhibitor. Clinical trials showed the favorable benefit-to-risk profile of DE compared to warfarin for the prevention of ischemic stroke in patients with atrial fibrillation. Remarkably, patients treated with dabigatran showed reduced rates of intracerebral hemorrhage compared to warfarin. As the breakdown of endothelial barrier integrity is associated with hemorrhagic events and as thrombin increases endothelial permeability, we hypothesized that dabigatran preserves the endothelial barrier by inhibiting thrombin-induced permeability...
