OBJECTIVE: Pulse wave velocity is a non-invasive method that is useful not only for estimating arterial stiffness but also screening cardiovascular events in the general population. Upstroke time (UT) and % mean artery pressure (% MAP) are novel, adjunctive indices for arterial stiffness that are derived from morphology analysis of the pulse wave during brachial-ankle pulse wave velocity (baPWV) measurement. Several studies have shown the association between UT and coronary artery calcification score as assessed by multi-detector computed tomography (MDCT)...

Spontaneous coronary artery dissection (SCAD) accounts approximately for 0.2% of cases of acute coronary syndrome. It is defined "spontaneous" in absence of any coronary wall damage. This disease affects primarily young women in good health, with no risk factors for coronary artery disease, especially during the postpartum period. Since the clinical presentation varies widely from no symptoms to typical angina and sudden cardiac death, SCAD incidence is underestimated.A 40-year-old woman, in the 8th week after delivery, was admitted to our emergency department because of acute chest pain, and a diagnosis of inferior and posterior non-ST-elevation myocardial infarction was made...

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an infrequently recognized but potentially fatal cause of acute coronary syndrome (ACS) that disproportionately affects women. Little is currently known about how patients with SCAD initially present. OBJECTIVES: We sought to describe patients who presented to the emergency department (ED) with symptoms of SCAD to improve providers' awareness and recognition of this condition. PATIENTS AND METHODS: We performed a retrospective medical record review of all patients who presented to the ED of a single academic medical center from January 1, 2002 through October 31, 2015 and were subsequently diagnosed with SCAD by angiography...

Spontaneous coronary artery dissection (SCAD) is an uncommon but important cause of acute coronary syndrome. The diagnosis of SCAD by an angiogram alone can be challenging and the increasing use of intracoronary imaging has proven an invaluable diagnostic adjunct in this regard. The appropriate initial management of SCAD has been a matter of significant debate. Owing to frequent spontaneous healing of coronary dissection and a higher risk of complications with percutaneous coronary intervention (PCI) in the setting of SCAD, a default approach of mechanical revascularization is not recommended...

Segmental colitis associated diverticulosis (SCAD) has become increasingly appreciated as a form of inflammatory disease of the colon. Several features suggest that SCAD is a distinct disorder. SCAD tends to develop almost exclusively in older adults, predominately, but not exclusively, males. The inflammatory process occurs mainly in the sigmoid colon, and usually remains localized to this region of the colon alone. SCAD most often presents with rectal bleeding and subsequent endoscopic visualization reveals a well localized process with non-specific histopathologic inflammatory changes...

BACKGROUND: Recurrent cardiovascular event remains high in stable coronary artery disease (SCAD), especially in patients with multiple risk factors, despite a high rate of use conventional treatment. Traditional Chinese Medicine (TCM) is a promising complementary and alternative medicine for treating SCAD, while evidence for its effect on long-term survival is limited. This study was designed to test if Chinese herbal medicine in addition to conventional treatment is more effective than conventional treatment alone in reducing major adverse cardiac event (MACE) for SCAD patients with multiple risk factors during a 1-year follow-up...

The segmental colitis associated with diverticulosis," better known by its acronym "SCAD," is a chronic inflammatory process localized in the colonic area presenting diverticulosis, and therefore mainly in the sigmoid colon. By definition, both the rectum and the right colon are spared from any inflammation both endoscopically and from a histologic point of view. Recent data have hypothesized that SCAD may be an independent clinical entity within the inflammatory bowel disease set of diseases. Compared with inflammatory bowel disease, SCAD seems to have a more benign outcome, with low rate of complications...

Background. The iterative sure independence screening (ISIS) is a popular method in selecting important variables while maintaining most of the informative variables relevant to the outcome in high throughput data. However, it not only is computationally intensive but also may cause high false discovery rate (FDR). We propose to use the FDR as a screening method to reduce the high dimension to a lower dimension as well as controlling the FDR with three popular variable selection methods: LASSO, SCAD, and MCP...

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. It occurs predominantly among younger females, typically in the absence of atherosclerotic coronary artery disease. Presentations vary greatly and this condition can be fatal. Given its rarity, there are no management guidelines. We present six patients with SCAD with different presentations and treatment approaches as examples in our literature review. Two patients presented with ST elevation myocardial infarction (STEMI), two with non-STEMI (NSTEMI), and two with cardiac arrest...

BACKGROUND: Cardiac Troponin I (cTnI) is frequently measured in patients presenting with symptomatic atrial fibrillation (AF). The significance of elevated cTnI levels in this patient cohort is unclear. We investigated the value of cTnI elevation in this setting and whether it is predictive for significant coronary artery disease (sCAD). METHODS: We conducted a retrospective, single-center, case-control study of 231 patients who presented with symptomatic AF to The Prince Charles Hospital emergency department, Brisbane, Australia between 2006 and 2014...

A 33-year-old woman with no premorbidities presented to us with chest pain and worsening dyspnoea since 1 week. Systemic examination was suggestive of acute pulmonary oedema and preliminary investigations revealed evolved anterior wall myocardial infarction (MI). The patient was stabilised and taken up for angiography which revealed spontaneous coronary artery dissection (SCAD) of the left anterior descending (LAD) artery. She underwent percutaneous coronary intervention (PCI) for the same. Further investigation into the cause for the SCAD came strongly positive for systemic lupus erythematosus (SLE)...

Ruminococcus champanellensis is a keystone species in the human gut that produces an intricate cellulosome system of various architectures. A variety of cellulosomal enzymes have been identified, which exhibit a range of hydrolytic activities on lignocellulosic substrates. We describe herein a unique R. champanellensis scaffoldin, ScaK, which is expressed during growth on cellobiose and comprises a cohesin module and a family 25 glycoside hydrolase (GH25). The GH25 is non-autolytic and exhibits lysozyme-mediated lytic activity against several bacterial species...

Identifying biomarker genes and characterizing interaction pathways with high-dimensional and low-sample size microarray data is a major challenge in computational biology. In this field, the construction of protein-protein interaction (PPI) networks using disease-related selected genes has garnered much attention. Support vector machines (SVMs) are commonly used to classify patients, and a number of useful tools such as lasso, elastic net, SCAD, or other regularization methods can be combined with SVM models to select genes that are related to a disease...
