It is unclear whether an evaluation incorporating coronary computed tomographic angiography (CCTA) more effective than standard in the emergency department patients with symptoms suggestive of acute syndromes.In this multicenter trial, we randomly assigned 40 to 74 years age syndromes but without ischemic electrocardiographic changes or initial positive troponin test early CCTA on weekdays during daylight hours between April 2010 and January 2012. The primary end point was length stay...
Purpose To evaluate the effect of tomosynthesis in diagnostic mammography on Breast Imaging Reporting and Data System (BI-RADS) final assessment categories over time. Materials Methods This retrospective study was approved by institutional review board. The authors reviewed all mammograms obtained during a 12-month interval before (two-dimensional [2D] [June 2, 2010, to June 1, 2011]) for 3 consecutive years after (tomosynthesis year 1 [2012], 2 [2013], [2014]) implementation tomosynthesis....
Participation in antiretroviral therapy (ART) programmes has been associated with greater utilization of care for hypertension and diabetes rural South Africa. The objective this study was to assess whether people living HIV on ART comorbid or also have improved chronic disease management indicators.
Pulmonary nodules (PNs) are often detected incidentally during coronary computed tomographic (CT) angiography, which is increasingly being used to evaluate patients with chest pain symptoms. However, the efficiency of following up on PN unknown.We determined demographic and clinical characteristics stable symptomatic referred for CT angiography in whom PNs warranted follow-up. A validated lung cancer simulation model was populated data from these patients, economic consequences follow-up per...
The purpose of this study is to compare the attenuation and homogeneity renal neoplasms with those cysts on contrast-enhanced CT.A total 129 24 simple were evaluated. Two readers determined whether each mass was qualitatively heterogeneous or homogeneous. Mean, minimum, maximum values measured. Statistical analysis performed.A 116 cell carcinomas (RCCs) (99 clear cell, four papillary, oncocytic, seven chromophobe, two unclassified RCCs), 13 homogeneous RCCs (10 one chromophobe RCC), (all...
Background— Coronary computed tomographic angiography (cCTA) allows rapid, noninvasive exclusion of obstructive coronary artery disease (CAD). However, concern exists whether implementation cCTA in the assessment patients presenting to emergency department with acute chest pain will lead increased downstream testing and costs compared alternative strategies. Our aim was compare observed actual usual care (UC) projected a strategy including early evaluation Rule Out Myocardial Infarction...
Obesity has been linked to severe clinical outcomes among people who are hospitalized with coronavirus disease 2019 (COVID-19). We tested the hypothesis that visceral adipose tissue (VAT) is associated in patients COVID-19, independent of body mass index (BMI).
Prolonged Holter monitoring of patients with cerebral ischemia increases the detection rate paroxysmal atrial fibrillation (PAF); this leads to improved antithrombotic regimens aimed at preventing recurrent ischemic strokes. The aim study was compare a 7-day-Holter (7-d-Holter) alone or in combination prior selection via transthoracic echocardiography (TTE) standard 24-h-Holter using cost-utility analysis. Lifetime cost, quality-adjusted life years (QALY), and incremental cost-effectiveness...
BackgroundHIV-infected patients are at increased risk of coronary artery disease (CAD). We evaluated the cost-effectiveness cardiac screening for HIV-positive men intermediate or greater CAD risk.
