BACKGROUND: Dobutamine stress contrast echo (DSCE) has a well-established prognostic value in the context of coronary artery disease (CAD). However, data regarding its prognostic capability separately in men and women are scarce. The aim of the current study was to assess gender-related differences in the prognostic performance of DSCE. METHODS: DSCE was performed in 2645 consecutive patients, who were classified in two groups depending on gender. Follow-up lasted 57...

PURPOSE: Measuring myocardial strain using two-dimensional speckle tracking echocardiography has emerged as a new tool to identify subclinical ventricular dysfunction. Abnormal strain has been shown to have superior sensitivity compared with dobutamine stress echocardiography for viability assessment; however, there is a paucity of data regarding the prediction of long-term major adverse cardiac events. We compared the prognostic ability of both global longitudinal strain (GLS) from resting echocardiograms to regional wall motion score index (WMSI) from stress echocardiograms in their ability to predict long-term major adverse cardiac events...

BACKGROUND: Objective data on chronic injuries of the medial collateral ligament (MCL) of the ankle are scarce. Chronic MCL injuries are frequently associated with lateral collateral ligament (LCL) injuries. For patients with chronic combined MCL and LCL injuries, the authors have performed simultaneous surgery of the 2 ligaments. HYPOTHESIS: Simultaneous surgery of the 2 ligaments may be effectively used to treat chronic combined MCL and LCL injuries. STUDY DESIGN: Case series; Level of evidence, 4...

Despite the evidence indicating that decision aids (DA) improve informed treatment decision making for prostate cancer (PCa), physicians do not routinely recommend DAs to their patients. We conducted semi-structured interviews with urologists (n = 11), radiation oncologists (n = 12) and primary care physicians (n = 10) about their methods of educating low-risk PCa patients regarding the treatment decision, their concerns about recommending DAs, and the essential content and format considerations that need to be addressed...

BACKGROUND: ST elevation Myocardial infarction is a medical emergency. A variety of noncardiac conditions had been known to mimic the ECG changes that are seen in acute coronary syndrome. Although the common ECG changes that are documented with raised intracranial pressure are T inversions, prolongation of QT interval and sinus bradycardia, ST elevation or depression, arrhythmias and prominent U waves have also been recognized. However, ST elevations in association with primary intracranial tumours are rarely reported...

Glycopeptide antibiotics inhibit the peptidoglycan biosynthesis in Gram-positive bacteria by targeting lipid II. This prevents the recycling of bactoprenol phosphate, the lipid transporter that is shared by peptidoglycan and wall teichoic acid biosyntheses. In this study, we investigate the effects of glycopeptide antibiotics on peptidoglycan and wall teichoic acid biosynthesis. The incorporation of d-[1-(13)C]alanine, d-[(15)N]alanine, and l-[1-(13)C]lysine into peptidoglycan and wall teichoic acid in intact whole cells of Staphylococcus aureus was measured using (13)C{(15)N} and (15)N{(13)C} rotational-echo double resonance NMR...

Stress echocardiography is an established technique for the assessment of extent and severity of coronary artery disease. The combination of echocardiography with a physical, pharmacological or electrical stress allows to detect myocardial ischemia with an excellent accuracy. A transient worsening of regional function during stress is the hallmark of inducible ischemia. Stress echocardiography provides similar diagnostic and prognostic accuracy as radionuclide stress perfusion imaging or magnetic resonance, but at a substantially lower cost, without environmental impact, and with no biohazards for the patient and the physician...

BACKGROUND: Arteriovenous fistula (AVF) maturation failure remains a major cause of morbidity and mortality in hemodialysis patients. The two major etiologies of AVF maturation failure are early neointimal hyperplasia development and persistent inadequate outward remodeling. Although hemodynamic changes following AVF creation may impact AVF remodeling and contribute to neointimal hyperplasia development and impaired outward remodeling, detailed AVF hemodynamics are not yet fully known...

Mitral valve disease represented by mitral stenosis and mitral regurgitation is the second most frequent valvulopathy. Mitral stenosis leads to an increased left atrial pressure whereas mitral regurgitation leads to an increased left atrial pressure associated with a volume overload. Secondary to an upstream transmission of this overpressure, both mitral stenosis and regurgitation lead to pulmonary hypertension and right heart failure. In addition, mitral regurgitation also leads to left ventricular dilatation and dysfunction with left heart failure...

Dynamic susceptibility contrast (DSC) perfusion MRI provide information about differences in macro- and microvasculature when executed with gradient-echo (GE; sensitive to macrovasculature) and spin-echo (SE; sensitive to microvasculature) contrast. This study investigated whether there are differences between macro- and microvascular transit time heterogeneity (MVTH and µVTH) and tissue oxygen tension (PO2mit) in newly-diagnosed and recurrent glioblastoma. Fifty-seven patients with glioblastoma (25 newly-diagnosed/32 recurrent) were examined with GE- and SE-DSC perfusion sequences, and a quantitative blood-oxygen-level-dependent (qBOLD) approach...

Takotsubo cardiomyopathy (TCM) is a unique type of cardiomyopathy characterised by left ventricular systolic dysfunction in association with stressful conditions. Patients with this condition usually present with chest pain and dyspnoea, and the presentation can mimic acute coronary syndrome. We present a case of a woman aged 58 years who presented with progressive dyspnoea and cough. Her initial evaluation was suggestive of acute myocardial infarction with elevated serum troponin T and ST segment elevation...

Introduction. Classically, stress-induced cardiomyopathy (SIC), also known as takotsubo cardiomyopathy, displays the pathognomonic feature of reversible left ventricular apical ballooning without coronary artery stenosis following stressful event(s). Temporary reduction in ejection fraction (EF) resolves spontaneously. Variants of SIC exhibiting mid-ventricular regional wall motion abnormalities have been identified. Recent case series present SIC as a finding in association with sudden unexplained death in epilepsy (SUDEP)...

A 56-year-old man presented to the Outpatient Cardiology Unit for dyspnea that had been lasting 6 months and an occasional episode of cold perspiration on climbing a flight of stairs. In the suspicion of coronary artery disease, he was prescribed a complete blood panel, an echocardiogram and a treadmill stress test. The echocardiogram, performed as late as 78 days after the first evaluation and only by chance scheduled 2 days before the stress test, enabled a diagnosis of left atrial myxoma for which the patient successfully underwent cardiac surgery...
