Sialocele and Its Association with Hypercortisolism and Long-Term Glucocorticoid Treatment in Dogs: Retrospective Case-Control Study.

Dogs with sialocele often have concurrent hypercortisolism or are receiving long-term glucocorticoid treatment. However, their association has not been investigated. This retrospective matched case-control study investigated the association between hypercortisolism, long-term glucocorticoid treatment, and sialocele in dogs.

Efficacy and safety of cilostazol-based triple antiplatelet therapy compared with clopidogrel-based dual antiplatelet therapy in patients with acute ST-elevation myocardial infarction undergoing percutaneous coronary intervention: A multicenter, randomized, open-label, phase 4 trial.

Background: Previous studies reported that compared to conventional dual antiplatelet therapy (DAT; aspirin + clopidogrel), triple antiplatelet therapy (TAT), involving the addition of cilostazol to DAT, had better clinical outcomes in patients with ST-elevation myocardial infarction (STEMI). However, the optimal duration of TAT is yet to be determined.

Methods: In total, 985 patients with STEMI who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) were prospectively enrolled in 15 PCI centers in South Korea and China.

Immediate versus staged complete revascularization in patients with ST-segment elevation myocardial infarction and multivessel coronary artery disease: results from a prematurely discontinued randomized multicenter trial.

Background: We aimed to compare clinical outcomes between immediate and staged complete revascularization in primary percutaneous coronary intervention (PCI) for treating ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD).

Methods: A total of 248 patients were enrolled in a prospective, randomized, and multicenter registry. Immediate revascularization was defined as one-time PCI of culprit and non-culprit lesions at the initial procedure.

Additional postdilatation using noncompliant balloons after everolimus-eluting stent implantation: Results of the PRESS trial.

Background: There are limited data on the clinical value of routine postdilatation using noncompliant balloons after contemporary drug-eluting stent implantation.

Hypothesis: Additional postdilatation using noncompliant balloons after everolimus-eluting stent implantation could provide better clinical outcomes.

Methods: We randomly assigned 1774 patients with coronary artery disease to undergo additional high-pressure postdilatation using noncompliant balloons and moderate-pressure dilatation using stent balloons after everolimus-eluting stent implantation.

High coronary calcium score and post-procedural CK-MB are noninvasive predictors of coronary stent restenosis.

Purpose: High coronary calcium score (CCS) and post-procedural cardiac enzyme may be related with poor outcomes in patients with coronary stent implantation.

Methods: A total of 1,072 patients (63.2% male, mean age: 61.

Well-Tolerated and Undiscovered Common Atrium until Late Adulthood.

Common atrium is a rare congenital heart disease characterized by complete absence of the interatrial septum, and is commonly accompanied by malformation of the atrioventricular valve. Most patients with common atrium experience symptoms during childhood. Here, we describe a patient with common atrium who experienced his first obvious symptom at 48 years of age.

Electrical and mechanical properties as a processing condition in polyvinylchloride multi walled carbon nanotube composites.

We investigated the electrical conductivity (sigma) and mechanical property of polyvinylchloride/carbon nanotube composites as a function of the CNT content and processing time during a solid-state process of high speed vibration mixing (HSVM) and high energy ball milling (HEBM). Both processes were suggested to avoid high temperatures, solvents, chemical modification of carbon nanotubes. In this study, the percolation threshold (phi(c)) for electrical conduction is about 1 wt% CNT with a sigma value of 0.

Independent determinants for presence and degree of left ventricular systolic dyssynchrony in treatment-naive patients with hypertension.

Objective: Prevalence of left ventricular systolic dyssynchrony (LVSD) is over 40% in treatment-naive patients with hypertension and it improves after chronic antihypertensive treatment. These findings might support the hypothesis that blood pressure (BP), BP-derived parameters, central BP, or arterial stiffness would contribute to LVSD. Therefore, we aimed to investigate possible factors associated with LVSD in treatment-naive patients with hypertension.

Three-dimensional heterostructure of metallic nanoparticles and carbon nanotubes as potential nanofiller.

The effect of the dimensionality of metallic nanoparticle-and carbon nanotube-based fillers on the mechanical properties of an acrylonitrile butadiene styrene (ABS) polymer matrix was examined. ABS composite films, reinforced with low dimensional metallic nanoparticles (MNPs, 0-D) and carbon nanotubes (CNTs, 1-D) as nanofillers, were fabricated by a combination of wet phase inversion and hot pressing. The tensile strength and elongation of the ABS composite were increased by 39% and 6%, respectively, by adding a mixture of MNPs and CNTs with a total concentration of 2 wt%.

Safety of dental extractions in coronary drug-eluting stenting patients without stopping multiple antiplatelet agents.

Background: The risk of excessive bleeding prompts physicians to stop multiple antiplatelet agents before minor surgery, which puts coronary stenting patients at risk for adverse thrombotic events.

Hypothesis: We hypothesized that most dental extractions can be carried out safely without stopping multiple antiplatelet agents.

Methods: All dental extraction patients who had undergone coronary stenting and who were also on oral multiple antiplatelet agents therapy were enrolled.

Change of coronary flow velocity during the cold pressor test is related to endothelial markers in subjects with chest pain and a normal coronary angiogram.

Background: Several studies demonstrated that endothelial or atherosclerotic biomarkers, including plasma free insulin-like growth factor-I(IGF-I), soluble CD40 ligand (sCD40L), adiponectin, and leptin have an influence on coronary endothelial function.

Hypothesis: The aim of the present study was to investigate whether change of coronary flow velocity of the distal left anterior descending artery (LAD) during the cold pressor test (CPT) with transthoracic Doppler echocardiography (TTE) was associated with these biomarkers in subjects with chest pain and a normal coronary angiogram.

Methods: In 190 subjects (mean age, 54±11 years; male:female, 113:77) with chest pain and a normal coronary angiogram, peak diastolic velocity (PDV) of the distal LAD during the CPT with TTE was assessed.

Association between plaque thickness of the thoracic aorta and recurrence of atrial fibrillation after ablation.

Background And Objectives: Several predictors of recurrence of atrial fibrillation (AF) after ablation have been identified, including age, type of AF, hypertension, left atrial diameter and impaired left ventricular ejection fraction. The aim of this study was to investigate whether the atherosclerotic plaque thickness of the thoracic aorta is associated with a recurrence of AF after circumferential pulmonary vein ablation (CPVA).

Subjects And Methods: Among patients with drug-refractory paroxysmal or persistent AF, 105 consecutive (mean age 58±11 years, male : female=76 : 29) patients who underwent transesophageal echocardiography and CPVA were studied.

Uptake of F-18 FDG and ultrasound analysis of carotid plaque.
