BACKGROUND: Severe noncompressible torso hemorrhage remains a leading cause of potentially preventable death in modern military conflicts. Resuscitative endovascular occlusion of the aorta (REBOA) has demonstrated potential as an effective adjunct to the treatment of noncompressible torso hemorrhage in the civilian early hospital and even prehospital settings-but the application of this technology for military prehospital use has not been well described. We aimed to assess the feasibility of both field and en route prehospital REBOA in the military exercise setting, simulating a modern armed conflict...

After a period of stagnation due to negative results of randomized trials for patients with symptomatic stenosis, the relevance of carotid artery stenting (CAS) is increasing again. CAS has become an important and evidence-based part of interventional stroke treatment. Our ability to manage acute recanalization of carotid occlusions and other niche indications properly led some skeptical neurologists to trust in carotid intervention for elective cases as well. The evolution of CAS from initial euphoria to more realistic views under consideration of trial results and guidelines is reviewed...

The medical advancements made during the wars in Iraq and Afghanistan have resulted in an unprecedented survival rate, yet there is still a significant number of deaths that were potentially survivable. Additionally, the ability to deliver casualties to definitive surgical care within the "golden hour" is diminishing in many areas of conflict. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been implemented successfully in the hospital setting. REBOA may be a possible adjunct for the Role I and point-of-injury (POI) care to provide temporary control of noncompressible torso hemorrhage (NCTH) and junctional hemorrhage...

OBJECTIVES: The aim of this study was to develop a hybrid approach-specific model to predict chronic total coronary artery occlusion (CTO) percutaneous coronary intervention success, useful for experienced but not ultra-high-volume operators. BACKGROUND: CTO percutaneous coronary intervention success rates vary widely and have improved with the "hybrid approach," but current predictive models for success have major limitations. METHODS: Data were obtained from consecutively attempted patients from 7 clinical sites (9 operators, mean annual CTO volume 61 ± 17 cases)...

OBJECTIVES: To analyze the procedural and clinical outcomes of carotid artery stenting (CAS) in the hands of endovascular trained vascular surgeons. METHODS: Between April 2008 to May 2013, 1197 patients were treated for extracranial internal carotid artery (ICA) stenosis. The proportion of endovascular treated patients was 5.0% (CAS n = 60 vs. carotid endarterectomy (CEA) n = 1137). All patients in the CAS group (44 males, median age 70 years) were treated by two senior vascular surgeons experienced in endovascular methods...

RATIONALE: Cervicocephalic artery dissections, once considered a rare disease, have become increasingly recognized as a cause of stroke in young and middle-aged individuals. Early diagnosis is mandatory because anticoagulation or antithrombotic therapy can help prevent primary or secondary ischemic events. However, the diagnosis is still a crucial challenge for radiologists and neurologists. PATIENT CONCERNS: We reported a rare case of 33-year-old patient with progressive ischemic stroke due to dissection from an intimal tear in the right proximal internal carotid artery to distal middle cerebral artery...

Localizing facial landmarks is a popular topic in the field of face analysis. However, problems arose in practical applications such as handling pose variations and partial occlusions while maintaining moderate training model size and computational efficiency still challenges current solutions. In this paper, we present a global shape reconstruction method for locating extra facial landmarks comparing to facial landmarks used in the training phase. In the proposed method, the reduced configuration of facial landmarks is first decomposed into corresponding sparse coefficients...

A series of our previous studies demonstrated that fish oil (FO), equivalent to 300mg/kg docosahexahenoic acid (DHA), facilitates memory recovery after transient, global cerebral ischemia (TGCI) in the aversive radial maze (AvRM). The present study sought to address two main issues: (i) whether the memory-protective effect of FO that has been observed in the AvRM can be replicated in the passive avoidance test (PAT) and object location test (OLT) and (ii) whether FO at doses that are lower than those used previously can also prevent TGCI-induced memory loss...

Human faces in surveillance videos often suffer from severe image blur, dramatic pose variations, and occlusion. In this paper, we propose a comprehensive framework based on Convolutional Neural Networks (CNN) to overcome challenges in video-based face recognition (VFR). First, to learn blur-robust face representations, we artificially blur training data composed of clear still images to account for a shortfall in real-world video training data. Using training data composed of both still images and artificially blurred data, CNN is encouraged to learn blur-insensitive features automatically...

PURPOSE: To propose a new algorithm of blood vessel segmentation based on regional and Hessian features for image analysis in retinal abnormality diagnosis. METHODS: Firstly, color fundus images from the publicly available database DRIVE were converted from RGB to grayscale. To enhance the contrast of the dark objects (blood vessels) against the background, the dot product of the grayscale image with itself was generated. To rectify the variation in contrast, we used a 5 × 5 window filter on each pixel...

The aim of the present study was to determine whether 10 days of repeated local heating was capable of inducing peripheral adaptations to the cutaneous vasculature, and to investigate potential mechanisms of adaptation. We also assessed maximal forearm blood flow to determine if repeated local heating affects maximal dilator capacity. METHODS: Before and after 10 days of heat training consisting of one-hour forearm exposures to 42°C water, or 32°C (control) in the contralateral arm (randomized and counterbalanced), we assessed hyperemia to rapid local heating of the skin (N=14 young, recreationally-active subjects)...

INTRODUCTION: Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage. Evidence indicates that exercise reduces the ischemia and reperfusion-induced brain damages in animal models of stroke. In the present study, the effect of exercise preconditioning on brain edema and neurological movement disorders following the cerebral ischemia and reperfusion in rats was investigated. METHODS: Twenty-one adult male wistar rats (weighing 260-300 g) were randomly divided into three groups: sham operated, exercise plus ischemia, and ischemia group (7 rats per group)...

BACKGROUND: Obese patients show a decline in exercise capacity and diverse degrees of dyspnea in association with mechanical abnormalities, increased ventilatory requirements secondary to the increased metabolic load, and a greater work of breathing. Consequently, obese patients may be particularly predisposed to the development of respiratory muscle fatigue during exercise. The aim of this study was to assess inspiratory muscle performance during incremental exercise in 19 obese male subjects (body mass index 41 ± 6 kg/m(2)) after aerobic exercise training using the noninvasive, inspiratory muscle tension-time index (TT0...
