BACKGROUND: Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes. OBJECTIVES: In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter...

We present a framework for combining a cardiac motion atlas with non-motion data. The atlas represents cardiac cycle motion across a number of subjects in a common space based on rich motion descriptors capturing 3D displacement, velocity, strain and strain rate. The non-motion data are derived from a variety of sources such as imaging, electrocardiogram (ECG) and clinical reports. Once in the atlas space, we apply a novel supervised learning approach based on random projections and ensemble learning to learn the relationship between the atlas data and some desired clinical output...

Various radiotherapy planning methods for T1N0 laryngeal cancer have been proposed to decrease normal tissue toxicity. We compare helical tomotherapy (HT), linac-based intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT), and 3-D conformal radiotherapy (3D-CRT) techniques for T1N0 laryngeal cancer. Overall, 10 patients with T1N0 laryngeal cancer were selected and evaluated. Furthermore, 10 radiotherapy treatment plans have been created for all 10 patients, including HT, IMRT, VMAT, and 3D-CRT...

BACKGROUND: Neoadjuvant chemoradiation therapy (CRT) increases pathological complete response (pCR) rates compared to radiotherapy alone in patients with stage II-III rectal cancer. Limited evidence addresses whether radiotherapy dose escalation further improves pCR rates. Our purpose is to measure the effects of radiotherapy dose and other factors on post-therapy pathologic tumor (ypT) and nodal stage in rectal cancer patients treated with neoadjuvant CRT followed by mesorectal excision...

The underlying mechanisms of cardioprotection of adiponectin (APN) against ischemia/reperfusion (I/R) injury remain largely unknown. The present study aimed to investigate whether calreticulin (CRT) mediated APN's cardioprotection against I/R injury. We inhibited mice cardiac CRT expression via intra-myocardial injection of CRT SiRNA, performed transient LAD ligation, measured the cardiac function, apoptosis and oxidative stress to identify CRT's effects on cardioprotective actions of APN against I/R injury in vivo...

BACKGROUND: Cluster randomised trials (CRTs) are a key instrument to evaluate public health interventions, particularly in low- and middle-income countries (LMICs). Fidelity assessment examines study processes to gauge whether an intervention was delivered as initially planned. Evaluation of implementation fidelity (IF) is required to establish whether the measured effects of a trial are due to the intervention itself and may be particularly important for CRTs of complex interventions...

Purpose: The advent of vascular endothelial VEGF antagonists has increased the therapeutic options for diabetic maculopathy considerably. However, there is a need to identify patients who respond favorably to the treatment from those in whom the treatment is less effective. The purpose of the present study was to test the hypothesis that the oxygen saturation in retinal vessels together with other risk factors can predict the effect of anti-VEGF treatment on diabetic maculopathy. Methods: In 73 eyes from 53 patients with center-involving diabetic macular edema, multiple linear regression was used to evaluate the predictive value of oxygen saturation in larger retinal vessels together with age, diabetes duration, diabetes type, hemoglobin A1c (HbA1c), mean arterial blood pressure (MAP), body mass index (BMI), previous retinal photocoagulation, visual acuity (VA), and central retinal thickness (CRT) before treatment as explanatory variables for VA and CRT after three monthly injections of anti-VEGF medication...

BACKGROUND: Multiple studies have sought to determine variables associated with improved "response" to cardiac resynchronization therapy(CRT). Such variables, however, are often derived from inadequately controlled, single center cohort studies calling external validity into question. We sought to determine predictors of response to CRT-D and CRT-P utilizing the methods of systematic review. METHODS: We searched MEDLINE, Embase®, and the Cochrane Central Register of Controlled Trials (CENTRAL) from January 1, 1995, as this is the date of first article reporting use of CRT through October 20, 2014...
