PURPOSE: To compare glaucoma progression between unilateral and bilateral disc hemorrhage (DH) eyes and to determine the associated risk factors. METHODS: A total of 78 bilateral primary open-angle glaucoma (POAG) patients who had shown one or more occurrences of DH (48 eyes of 38 unilateral DH patients and 30 eyes of 30 bilateral DH patients) were included. Glaucoma progression was defined by visual field (VF) deterioration. The mean VF global indices progression rates in the pre-DH, post-DH and total follow-up periods were compared between the unilateral and bilateral DH groups...

The fracture liaison service (FLS) care is considered the most appropriate organizational approach for secondary fracture prevention. We performed a literature search to evaluate to what extent the introduction of a FLS reduced subsequent fracture rates. We identified five studies that compared subsequent fracture rates. These studies varied in study design, proportion of women, baseline and subsequent fracture type [vertebral fracture (VF), non-VF (NVF) or hip fractures], duration of follow-up, response rates of attending the FLS, as well as variables included in adjusted analyses (age, sex, baseline fracture, time dependency)...

CONTEXT: Verbal and tactile feedback during rehabilitation exercises can improve muscle activation, thus improving the therapeutic benefits. However, it is unclear which feedback method elicits the greatest electromyographic (EMG) amplitude. OBJECTIVE: To determine if the addition of tactile to verbal feedback increases EMG amplitude of selected shoulder musculature during scapular plane elevation (Y's), shoulder horizontal abduction with external rotation (T's), and scapular retraction with external rotation (W's)...

PURPOSE: Deep glaucomatous defects near fixation were followed over time with an adaptive optics-scanning light ophthalmoscope (AO-SLO) to better understand the progression of these defects and to explore the use of AO-SLO in detecting them. METHODS: Six eyes of 5 patients were imaged with an AO-SLO from 2 to 4 times for a range of 14.6 to 33.6 months. All eyes had open-angle glaucoma with deep defects in the superior visual field (VF) near fixation as defined by 10-2 VFs with 5 or more points less than -15 dB; two of the eyes had deep defects in the inferior VF as well...

The egocentric reference frame is essential for body orientation and spatial localization of external objects. Recent neuroimaging and lesion studies have revealed that the right hemisphere of humans may play a more dominant role in processing egocentric information than the left hemisphere. However, previous studies of egocentric discrimination mainly focused on assessing the accuracy of egocentric judgment, leaving its timing unexplored. In addition, most previous studies never monitored the subjects' eye position during the experiments, so the influence of eye position on egocentric judgment could not be excluded...

BACKGROUND: The development of prognostic factors of life-threatening ventricular tachyarrhythmias (VTA) and sudden cardiac death (SCD) continues to maintain its priority and relevance in cardiology. The development of a method of personalised prognosis based on multifactorial analysis of the risk factors associated with life-threatening heart rhythm disturbances is considered a key research and clinical task. AIM: To design a prognostic and mathematical model to define personalised risk for life-threatening VTA in patients with chronic heart failure (CHF)...

Electrocardiographic mapping (ECM) is a non invasive technique using body surface potentials and CT geometry to reconstruct epicardial maps. ECM is emerging as an important tool not only for diagnostic mapping, but also as a guide for trans-catheter ablation of complex arrhythmias such as atrial fibrillation. It provides the clinician with an immediate global view of the substrate, allowing easier pre-procedural planning, potential improving clinical outcomes. Panoramic mapping of ventricular fibrillation (VF) is helping to develop a better understanding of its physiology, with future implications for the identification of therapeutic targets in patients with structural heart disease, as well as in idiopathic VF...

Adil Sattar, Shmuel Inbar
This report highlights the importance of realising that even the modern-day implantable cardioverter defibrillators (ICDs) with R wave synchronised appropriate shocks have a potential proarrhythmic effect. We present two cases of ventricular fibrillation induction resulting from an appropriate ICD shock observed in two different patients at our institution. Such cases have not been reported before. We discuss the possible reasons for our observations and are also submitting a pertinent literature review with our reports...

The combination of momentum microscopy (high resolution imaging of the Fourier plane) with an imaging spin filter has recently set a benchmark in k-resolution and spin-detection efficiency. Here we show that the degree of parallelization can be further increased by time-of-flight energy recording. On the quest towards maximum information (in earlier work termed "complete" photoemission experiment) we have studied the prototypical high-Z fcc metal iridium. Large partial bandgaps and strong spin-orbit interaction lead to a sequence of spin-polarized surface resonances...

Background Arrhythmogenic right ventricular dysplasia (ARVD) is a heritable disorder characterized by fibro-fatty replacement of right ventricular myocytes, increased risk of ventricular arrhythmias, and sudden cardiac death. Galectin-3 (GAL3) is known to play an important role in a number of fibrotic conditions, including cardiac fibrosis. Many studies have focused on the association between GAL3 levels and cardiac fibrosis in heart failure. However, the role of GAL3 in the pathogenesis of ARVD and ventricular arrhythmias has not yet been evaluated thoroughly...

Mountaintop removal coal mining (MTM) is a form of surface mining where ridges and mountain tops are removed with explosives to access underlying coal seams. The crushed rock material is subsequently deposited in headwater valley fills (VF). We examined how this added water storage potential affects streamflow using a paired watershed approach consisting of two sets of mined and unmined watersheds in West Virginia. The mined watersheds exported 7-11% more water than the reference watersheds, primarily due to higher and more sustained baseflows...

Mucopolysaccharidosis type VII (MPS VII) is caused by β-glucuronidase deficiency, resulting in lysosomal accumulation of glycosaminoglycans (GAGs) and multisystemic disease. We present cardiovascular gross and histopathology findings from a 11-year-old MPS VII male, who expired after developing ventricular fibrillation following anesthesia induction. Gross anatomic observations were made at autopsy; postmortem formalin-fixed paraffin-embedded samples of the carotid artery, aorta, myocardium, and valves were sectioned and stained with hematoxylin-eosin, Verhoeff-Van Gieson, CD68, and trichrome stains...

BACKGROUND: Cardiac arrest (CA) is a leading cause of death in the United States, claiming over 450 000 lives annually. Improving survival depends on the ability to conduct CA research and on the translation and implementation of research findings into practice. Our objective was to provide a descriptive analysis of annual National Institutes of Health (NIH) funding for CA research over the past decade. METHOD AND RESULTS: A search within NIH RePORTER for the years 2007 to 2016 was performed using the terms: "cardiac arrest" or "cardiopulmonary resuscitation" or "heart arrest" or "circulatory arrest" or "pulseless electrical activity" or "ventricular fibrillation" or "resuscitation...

INTRODUCTION: Out-of-hospital cardiac arrest (OHCA) has an annual incidence of approximately 60 000 in the UK. Less than 10% of those who receive resuscitation survive to hospital discharge. For OHCA of a presumed cardiac cause, the optimal antiplatelet therapy is currently unknown. Previous studies indicate that a procoagulopathic state exists postcardiac arrest which may contribute to the formation of thrombi and contribute to poor outcomes. However, the administration of antiplatelet therapies needs to be balanced against the increased risk of bleeding that these individuals face...

PURPOSE: The only drugs available to treat alveolar echinococcosis (AE) are mostly parasitostatic and in many cases prescribed for life. Decision criteria for discontinuation rely on the absence of parasitic viability. The aim of the present study was to search for candidate proteins that may exhibit good potential as biomarkers for viability. EXPERIMENTAL DESIGN: Sixteen serum samples (5 healthy controls,11 patients with AE), were used. AE-patients were classified into 3 groups 'Cured' (n = 2), 'ABZ-responders' (n = 4) and 'ABZ-non responders' (n = 5)...

Development of children's cognitive and perceptual skills depends heavily on object exploration and experience in their physical world. For children who have severe physical impairments, one of the biggest concerns is the loss of opportunities for meaningful play with objects, including physical contact and manipulation. Assistive robots can enable children to perform object manipulation through the control of simple interfaces. Touch sensations conveyed through haptic interfaces in the form of force reflection or force assistance can help a child to sense the environment and to control a robot...
