BACKGROUND: Antiphospholipid antibody syndrome (APS) is a disorder associated with both arterial and venous thromboembolic disease, including acute myocardial infarction (AMI). Given that management with anticoagulants is critical and differs from usual AMI care, identification of key discriminators of patients with AMI with APS is important. METHODS: We performed an English-language systematic review of the literature of cases and case series of patients with AMI and APS from inception until 20 March 2016, collecting demographics, investigations, and outcomes...

BACKGROUND: Whether patients with acute myocardial infarction presenting with new or presumed new left bundle-branch block (LBBB) should be treated in the same way as those presenting with ST-elevation (STE) is still a matter of debate. METHODS: Data from 28,358 patients enrolled in AMIS Plus from 1997 to 2016 were analyzed to evaluate differences in treatment and outcome of patients presenting with LBBB (n=2295) or STE (n=26,090) on their initial electrocardiogram using descriptive statistics and multivariate logistic regression...

Design of fluorogenic probes for Halo-tag is highly desirable but challenging. Previous work achieved this goal by controlling the chemical switch of spirolactones upon the covalent conju-gation between Halo-tag and probes or by incorporating a 'channel dye' into the substrate bind-ing tunnel of Halo-tag. In this work, we have developed a novel class of Halo-tag fluorogenic probes that are derived from solvatochromic fluorophores. The optimal probe, harboring a ben-zothiadiazole scaffold, exhibits a 1000-fold fluorescence enhancement upon reaction with Halo-tag...

BACKGROUND: Previous studies have suggested that antithrombin may be beneficial for treating coagulopathy in patients with severe burns. However, robust evidence for this idea is lacking. We examined the hypothesis that antithrombin may be effective in treating patients with severe burns. METHODS: We performed propensity score-matched analyses of the nationwide administrative Japanese Diagnosis Procedure Combination inpatient database. We identified patients with severe burns (burn index ≥ 10) who were recorded in the database from 1 July 2010 to 31 March 2013...

A cardiocerebral ischemic attack (CCI) or a concurrent acute ischemic stroke (AIS) and myocardial infarction (AMI) is a severe event with no clear recommendations for ideal management because of the rarity of the scenario. The narrow time window for treatment and complexity of the treatment decision puts immense pressure on the treating physician. We evaluated this challenging situation at our tertiary center. Using our prospective stroke database out of a total of 555 patients with acute ischemic stroke between 2009 and 2014, we identified five consecutive cases with CCI (incidence 0...

Analysis of a contemporary cohort of patients on dialysis revealed that mortality from acute myocardial infarction (AMI) has decreased, whereas the prevalence of AMI has increased markedly, particularly among patients with non-ST elevation myocardial infarction (NSTEMI). Using inpatient discharge diagnosis codes (1993-2008), we determined that proportions of AMI claims decreased in the primary position (from 65% to 52%) but increased in the secondary position (from 35% to 48%). Proportions of NSTEMI codes increased remarkably in both the primary and secondary positions...

INTRODUCTION: Prior studies have demonstrated an increased risk of cancer-associated scleroderma in patients with RNA polymerase III (POL) autoantibodies and in patients negative for anti-centromere (CENP), anti-topoisomerase-1 (TOPO), and anti-POL antibodies (referred to as CENP/TOPO/POL (CTP)-Negative). In a recent study of 16 CTP-negative scleroderma patients with coincident cancer, we found that 25% had autoantibodies to RNPC3, a member of the minor spliceosome complex. In this investigation, we validated the relationship between anti-RNPC3 antibodies and cancer and examined the associated clinical phenotype in a large sample of scleroderma patients...

Troponin elevation is required to diagnose acute myocardial infarction (AMI), yet elevated values are often encountered in noncardiac disease states. We evaluated inpatient (IP) and outpatient (OP) encounters at 14 hospitals in calendar year 2014 and found that troponin assays were performed during 12% of all OP visits and 29% of all IP visits: 82,853 encounters in all. We employed an expert panel to estimate the likelihood of AMI based on primary International Statistical Classification of Diseases and Related Health Problems, 9th edition diagnoses...

Sialidase cleaves sialic acids on the extracellular cell surface as well as inside the cell, and is necessary for normal long-term potentiation (LTP) at MF-CA3 pyramidal cell synapses and for hippocampus-dependent spatial memory. Here, we investigated in detail the role of sialidase in memory processing. Sialidase activity measured with 4MU-Neu5Ac or X-Neu5Ac and FRV LB was increased by high K(+)-induced membrane depolarization. Sialidase activity was also increased by chemical LTP induction with forskolin and activation of BDNF signaling, non-NMDARs or NMDARs...

<i>Objective:</i> Proprioceptive mechanisms play a critical role in both reflexive and volitional lower extremity control. Significant strides have been made in the development of bionic limbs that are capable of bi-directional communication with the peripheral nervous system, but none of these systems have been capable of providing physiologically-relevant muscle-based proprioceptive feedback through natural neural pathways. In this study, we present the Agonist-antagonist Myoplastic Interface (AMI), a surgical approach with the capacity to provide graded kinesthetic feedback from a prosthesis through mechanical activation of native mechanoreceptors within residual agonist-antagonist muscle pairs...

Background -Depression among patients with acute myocardial infarction (AMI) is prevalent and associated with an adverse quality of life and prognosis. Despite recommendations from some national organizations to screen for depression, it is unclear whether treatment of depression in patients with AMI is associated with better outcomes. We aimed to determine whether prognosis of patients with treated vs. untreated depression differs. Methods -The TRIUMPH study is an observational multi-center cohort study that enrolled 4,062 patients aged ≥18 years with AMI between April 11, 2005 and December 31, 2008 from 24 US hospitals...

OBJECTIVE: Circulating microparticles (cMPs) are phospholipid-rich vesicles released from cells when activated or injured, and contribute to the formation of intracoronary thrombi. Tissue factor (TF, CD142) is the main trigger of fibrin formation and TF-carrying cMPs are considered one of the most procoagulant cMPs. Similar types of atherosclerotic lesions may lead to different types of AMI, although the mechanisms behind are unresolved. Therefore, we aimed to investigate the phenotype of cMPs found in plasma of ACS patients and its relation to AMI severity and thrombotic burden...
