A 36-year-old man started to climb Mount Fuji (3776m above sea level: ASL), from the Gotemba new fifth station (2400m ASL). He had no significant medical history, and this was his first attempt to climb such a high mountain. He began feeling chest discomfort but continued to climb. When he reached the ninth station of the mountain (3600mASL), he lost consciousness. One individual immediately provided basic life support using an automated external defibrillator (AED) that was located in the station. After electroshocks, he regained consciousness...

This paper investigates the adaptive H∞ static output feedback (SOF) control problem for continuous-time linear systems with stochastic sensor failures. A multi-Markovian variable is introduced to denote the failure scaling factors for each sensor. Different from the existing results, the failure parameters are stochastically jumping and their bounds of are unknown. An adaptive reliable H∞ SOF control method is proposed, where the controller parameters are updated automatically to compensate for the failure effects on systems...

From 1 January 2005 through 31 December 2014, a total of 8,819 incident diagnoses of non-melanoma skin cancer (NMSC) (incidence rate 64.6 cases per 100,000 person-years [p-yrs]) were documented in the health records of 6,670 active component service members. During the surveillance period, there was a very slight decrease in the annual crude incidence rates of NMSC; rates of NMSC peaked in 2007 (68.3 cases per 100,000 p-yrs) and were at their lowest in 2013 (60.4 cases per 100,000 p-yrs). Increasing age was associated with increased risk of NMSC...

BACKGROUND: Clinical heart failure (HF) occurs frequently after ST-segment elevation myocardial infarction (STEMI), and is associated with increased mortality. We assessed the impact of remote ischemic peri-conditioning (RIPC) during inter-facility air medical transport of STEMI patients on clinical HF following primary percutaneous coronary intervention (pPCI). METHODS: Data from Acute Coronary Treatment and Intervention Outcomes Network Registry®-Get With the Guidelines™ (ACTION Registry-GWTG) from two PCI-hospitals that are utilizing RIPC during inter-facility helicopter transport of STEMI patients for pPCI between March, 2013 and September, 2015 were used for this study...

Traumatic injury is a significant cause of morbidity and mortality in the United States. Massive hemorrhage is responsible for the vast majority of deaths. Evolution in trauma treatment has resulted in major improvements to emergency care. Tranexamic acid (TXA), an antifibrinolytic agent, is synthetically derived from amino acids. The CRASH-2 study demonstrated that the early administration of TXA results in significant decreases in morbidity and mortality. Experiences by coalition forces in Southwest Asia found a substantial increase in survival of trauma patients with early TXA administration...

In April 2015 a 7.8-magnitude earthquake hit Nepal. As part of relief operations named Operation Maitri, the Indian Armed Forces deployed 3 field hospitals in the disaster zone. Rapid deployment of mobile surgical teams to far-flung, inaccessible areas was done by helicopters. In an operational deployment spanning 1 month, a total of 7532 patients were treated and 105 surgeries were carried out on 83 patients. One-fifth of the patients were less than 18 years of age. One-third of the patients had traumatic injuries directly attributable to the earthquake, whereas the remaining patients were treated for diseases of poor sanitation and hygiene as well as chronic illness that had been neglected owing to the collapse of the local health infrastructure...

BACKGROUND: Trauma systems in remote and rural regions often rely on helicopter emergency medical services to facilitate access to definitive care. The siting of such resources is key, but often relies on simplistic modelling of coverage, using circular isochrones. Scotland is in the process of implementing a national trauma network, and there have been calls for an expansion of aeromedical retrieval capacity. The aim of this study was to analyse population and area coverage of the current retrieval service configuration, with three aircraft, and a configuration with an additional helicopter, in the North East of Scotland, using a novel methodology...

INTRODUCTION: Injured children may be transported to trauma centers by helicopter air ambulance (HAA); however, a benefit in outcomes to this expensive resource has not been consistently shown in the literature and there is concern that HAA is over-utilized. A study that adequately controls for selection biases in transport mode is needed to determine which injured children benefit from HAA. The purpose of this study was to determine if HAA impacts mortality differently in minimally and severely injured children and if there are predictors of over-triage of HAA in children that can be identified...

Lower canopy temperature (CT), resulting from increased stomatal conductance, has been associated with increased yield in wheat. Historically, CT has been measured with hand-held infrared thermometers. Using the hand-held CT method on large field trials is problematic, mostly because measurements are confounded by temporal weather changes during the time required to measure all plots. The hand-held CT method is laborious and yet the resulting heritability low, thereby reducing confidence in selection in large scale breeding endeavors...

Health emergency medical service (HEMS) plays an important role in reducing injuries by providing advanced medical care in the shortest time and reducing the transfer time to advanced treatment centers. In the regions without ground relief coverage, it would be faster to transfer emergency patients to the hospital by a helicopter. In this paper, an integer nonlinear programming model is presented for the integrated locating of helicopter stations and helipads by considering uncertainty in demand points. We assume three transfer modes: (1) direct transfer by an ambulance, (2) transfer by an ambulance to a helicopter station and then to the hospital by a helicopter, (3) transfer by an ambulance to a predetermined point and then to the hospital by a helicopter...

This paper presents an algorithm for velocity-aided attitude estimation for helicopter aircraft using a microelectromechanical system inertial-measurement unit. In general, high- performance gyroscopes are used for estimating the attitude of a helicopter, but this type of sensor is very expensive. When designing a cost-effective attitude system, attitude can be estimated by fusing a low cost accelerometer and a gyro, but the disadvantage of this method is its relatively low accuracy. The accelerometer output includes a component that occurs primarily as the aircraft turns, as well as the gravitational acceleration...

Brain-computer interface (BCI) technologies aim to provide a bridge between the human brain and external devices. Prior research using non-invasive BCI to control virtual objects, such as computer cursors and virtual helicopters, and real-world objects, such as wheelchairs and quadcopters, has demonstrated the promise of BCI technologies. However, controlling a robotic arm to complete reach-and-grasp tasks efficiently using non-invasive BCI has yet to be shown. In this study, we found that a group of 13 human subjects could willingly modulate brain activity to control a robotic arm with high accuracy for performing tasks requiring multiple degrees of freedom by combination of two sequential low dimensional controls...

BACKGROUND: Survival rates from out-of-hospital cardiac arrest (OHCA) remain low, despite remarkable efforts to improve care. A number of ambulance services in the United Kingdom (UK) have developed prehospital critical care teams (CCTs) which attend critically ill patients, including OHCA. However, current scientific evidence describing CCTs attending OHCA is sparse and research to date has not demonstrated clear benefits from this model of care. METHODS: This prospective, observational study will describe the effect of CCTs on survival from OHCA, when compared to advanced-life-support (ALS), the current standard of prehospital care in the UK...
