Breviscapine is a flavonoid derived from a traditional Chinese herb Erigerin breviscapus (Vant.) Hand-Mazz, and has been extensively used in clinical treatment for cerebral stroke in China, but the underlying pharmacological mechanisms are still unclear. In present study, we investigated whether breviscapine could confer a neuroprotection against cerebral ischemia injury by targeting autophagy mechanisms. A cerebral stroke model in Sprague-Dawley rats was prepared by middle cerebral artery occlusion (MCAO), rats were then randomly divided into 5 groups: MCAO+Bre group, rats were treated with breviscapine; MCAO+Tat-Beclin-1 group, animals were administrated with specific autophagy inducer Tat-Beclin-1; MCAO+Bre+Tat-Beclin-1 group, rats were treated with both breviscapine and Tat-Beclin-1, MCAO+saline group, rats received the same volume of physiological saline, and Sham surgery group...

Approximately 1.5% of hospital patients develop hospital acquired pneumonia. Aspiration is the major risk factor for pneumonia and is associated with reduced ability to mechanically clear respiratory pathogens into the stomach. Currently non-invasive methods of diagnosing hospital acquired pneumonia are less robust than invasive methods, and lead to over-diagnosis. Accurate diagnosis is key to surveillance, prevention and treatment of HAP, and also to improving outcomes; newer imaging modalities such as phase contrast X-ray imaging and nanoparticle enhanced magnetic resonance imaging may help...

Atrial fibrillation (AF) is the most prevalent sustained arrhythmia found in clinical practice. AF rarely exists as a single entity but rather as part of a diverse clinical spectrum of cardiovascular diseases, related to structural and electrical remodeling within the left atrium, leading to AF onset, perpetuation, and progression. Due to the high overall prevalence within the AF population arterial hypertension plays a significant role in the pathogenesis of AF and its complications. Fibroblast proliferation, apoptosis of cardiomyocytes, gap junction remodeling, accumulation of collagen both in atrial and ventricular myocardium all accompany ageing-related structural remodeling with impact on electrical activity...

Posterior reversible encephalopathy syndrome (PRES), may be due to different causes. It may develop secondary to hypertension, renal decompensation, electrolyte imbalance, and chemotherapeutic drugs. We describe a case of acute lymphoblastic leukemia in which PRES developed secondary to hyponatremia despite being normotensive during receipt of chemotherapy. Magnetic resonance imaging findings were suggestive of PRES. Partial diffusion restriction was observed in lesions in the bilateral occipitoparietal regions and the cerebellum...

Rivaroxaban is an oral direct factor Xa inhibitor approved for the treatment of stroke and systemic thromboembolism in patients with non-valvular atrial fibrillation. Despite its efficacy, rivaroxaban therapy results in adverse effects and complications, such as bleeding. Angiotensin II (AngII) is implicated in many cardiovascular conditions, such as hypertension and heart failure. In this study, we investigate whether AngII influences anticoagulant effects of rivaroxaban by using an experimental mouse model with type 2 diabetes mellitus and advanced glycation end product (AGE)-exposed human umbilical vein endothelial cells (HUVECs)...

INTRODUCTION: Overall, intra-arterial treatment (IAT) proved to be beneficial in patients with acute ischaemic stroke due to a proximal occlusion in the anterior circulation. However, heterogeneity in treatment benefit may be relevant for personalised clinical decision-making. Our aim is to improve selection of patients for IAT by predicting individual treatment benefit or harm. METHODS AND ANALYSIS: We will use data collected in the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN) trial to analyse the effect of baseline characteristics on outcome and treatment effect...

BACKGROUND AND PURPOSE: Some have argued that it may be beneficial to expand the availability of endovascular revascularization services to lower-volume hospitals to minimize the morbidity associated with transfer to larger endovascular centers. We compared the outcomes after revascularization of patients directly admitted to a low-volume center and those transferred to a high-volume center. METHODS: We searched a national database of hospital-reported outcomes for patients who underwent endovascular revascularization for acute ischemic stroke...

BACKGROUND: Transitions of care from specialty and acute settings to primary care abound. Compared to the continuity in end-of-shift handoffs, care transitions involve provider communication between practices and facilities with their own cultures and bureaucracies. Using the transition from acute care to outpatient primary care for stroke/transient ischemic attack (TIA) patients as a case study, this qualitative research explored communication practices and institutional arrangements among clinical providers responsible for longitudinal management of hypertension...

BACKGROUND: Antihypertensive medication decreases risk of cardiovascular disease (CVD) events in adults with hypertension. Although black adults have higher prevalence of hypertension and worse CVD outcomes compared with whites, limited attention has been given to the cost-effectiveness of antihypertensive medication for blacks. OBJECTIVE: To compare the cost-effectiveness of antihypertensive medication treatment versus no-treatment in white and black adults. RESEARCH DESIGN: We constructed a State Transition Model to assess the costs and quality-adjusted life-years (QALYs) associated with either antihypertensive medication treatment or no-treatment using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study and published literature...
