    We develop a path-planning algorithm to guide autonomous amphibious vehicles (AAVs) for flood rescue support missions. Specifically, we develop an algorithm to control multiple AAVs to reach/rescue multiple victims (also called targets) in a flood scenario in 2D, where the flood water flows across the scene and the targets move (drifted by the flood water) along the flood stream. A target is said to be rescued if an AAV lies within a circular region of a certain radius around the target. The ...

    Penetrating cardiac injury tends to generally be repaired without cardiopulmonary bypass in the operating room. We herein report the case of penetrating cardiac injury repaired using percutaneous cardiopulmonary support in an emergency room. A 57-year-old man attempted suicide by stabbing himself in the left anterior chest with a knife. Although the patient suffered cardiopulmonary arrest for 7 min in the ambulance, spontaneous circulation was restored following pericardiotomy through emergency left thoracotomy in the emergency room. To prevent coronary artery injury and control the massive bleeding, percutaneous cardiopulmonary support was instituted without systemic heparinization and the cardiac injury was repaired in the emergency room. The patient was then transferred to another hospital on day 46 for further rehabilitation. Percutaneous cardiopulmonary support might be helpful for treating critical patients in an emergency room, even in the case of trauma patients. PMID:17342366

    Intraoperative thoracic surgical catastrophes may require extracorporeal circulation modes to support the patient while the appropriate repair is made. Teamwork is key and, given the evidence supporting better performance with the use of simulation and surgical-crisis checklists, their use should be encouraged. Anticipation is another important factor because the results of intrathoracic malignancy resection are clearly superior in the setting of planned cardiopulmonary support. In addition, familiarity with the different modes of support that are currently available can direct the decision-making process toward the best option to facilitate resolution of the intraoperative catastrophe with the least related morbidity.

    Full Text Available Abstract Background Immediate bystander cardiopulmonary resuscitation (CPR significantly improves survival after a sudden cardiopulmonary collapse. This study assessed the basic life support (BLS knowledge and performance of high school students before and after CPR training. Methods This study included 132 teenagers (mean age 14.6 ± 1.4 years. Students completed a two-hour training course that provided theoretical background on sudden cardiac death (SCD and a hands-on CPR tutorial. They were asked to perform BLS on a manikin to simulate an SCD scenario before the training. Afterwards, participants encountered the same scenario and completed a questionnaire for self-assessment of their pre- and post-training confidence. Four months later, we assessed the knowledge retention rate of the participants with a BLS performance score. Results Before the training, 29.5% of students performed chest compressions as compared to 99.2% post-training (P P Conclusions BLS training in high school seems highly effective considering the minimal amount of previous knowledge the students possess. We observed significant improvement and a good retention rate four months after training. Increasing the number of trained students may minimize the reluctance to conduct bystander CPR and increase the number of positive outcomes after sudden cardiopulmonary collapse.

    Minimizing the systemic inflammatory response caused by cardiopulmonary bypass is a major concern. It has been suggested that the perfusion temperature affects the inflammatory response. The aim of this prospective study was to compare the effects of moderate hypothermia (32°C) and normothermia (36°C) during cardiopulmonary bypass on markers of the inflammatory response and clinical outcomes (time on ventilator) after surgical closure of ventricular septal defects. During surgical closure of ventricular septal defects under cardiopulmonary bypass, 20 children (median age 4.9 months, range 2.3-38 months; median weight 7.2 kg, range 5.2-11.7 kg) were randomized to a perfusion temperature of either 32°C (Group 1, n = 10) or 36°C (Group 2, n = 10). The clinical data and blood samples were collected before cardiopulmonary bypass, directly after aortic cross-clamp release, and 4 and 24 h after weaning from cardiopulmonary bypass. Time on ventilation as primary outcome did not differ between the two groups. Other clinical outcome parameters like fluid balance or length of stay in the intensive care were also similar in the two groups. Compared with Group 2, Group 1 needed significantly higher and longer inotropic support (P Perfusion temperature did not influence cytokine release, organ injury, or coagulation. Cardiopulmonary bypass temperature does not influence time on ventilation or inflammatory marker release. However, in the present study, with a small patient cohort, patients operated under hypothermic bypass needed higher and longer inotropic support. The use of hypothermic cardiopulmonary bypass in infants and children should be approached with care. PMID:26581834

    Cerebral metabolic alterations during cardiac arrest, cardiopulmonary resuscitation (CPR) and extracorporeal cardiopulmonary life support (ECLS) are poorly explored. Markers are needed for a more personalized resuscitation and post—resuscitation care. Aim of this study was to investigate early metabolic changes in the hippocampal CA1 region during ventricular fibrillation cardiac arrest (VF-CA) and ECLS versus conventional CPR. Male Sprague-Dawley rats (350g) underwent 8min untreated VF-CA followed by ECLS (n = 8; bloodflow 100ml/kg), mechanical CPR (n = 18; 200/min) until return of spontaneous circulation (ROSC). Shams (n = 2) were included. Glucose, glutamate and lactate/pyruvate ratio were compared between treatment groups and animals with and without ROSC. Ten animals (39%) achieved ROSC (ECLS 5/8 vs. CPR 5/18; OR 4,3;CI:0.7–25;p = 0.189). During VF-CA central nervous glucose decreased (0.32±0.1mmol/l to 0.04±0.01mmol/l; p<0.001) and showed a significant rise (0.53±0.1;p<0.001) after resuscitation. Lactate/pyruvate (L/P) ratio showed a 5fold increase (31 to 164; p<0.001; maximum 8min post ROSC). Glutamate showed a 3.5-fold increase to (2.06±1.5 to 7.12±5.1μmol/L; p<0.001) after CA. All parameters normalized after ROSC with no significant differences between ECLS and CPR. Metabolic changes during ischemia and resuscitation can be displayed by cerebral microdialysis in our VF-CA CPR and ECLS rat model. We found similar microdialysate concentrations and patterns of normalization in both resuscitation methods used. Institutional Protocol Number: GZ0064.11/3b/2011 PMID:27175905

    An alternate physiologic pulsatile pump (PPP) system was designed and evaluated to produce sufficient pulsatility during neonate-infant open heart surgery. This hydraulically driven pump system has a unique "dual" pumping chamber mechanism. The first chamber is placed between the venous reservoir and oxygenator and the second chamber between the oxygenator and patient. Each chamber has two unidirectional tricuspid valves. Stroke volume (0.2-10 ml), upstroke rise time (10-350 msec), and pump rate (2-250 beats per minute [bpm]) can be adjusted independently to produce adequate pulsatility. This system has been tested in 3-kg piglets (n = 6), with a pump flow of 150 ml/kg/min, a pump rate of 150 bpm, and a pump ejection time of 110 msec. After initiation of cardiopulmonary bypass (CPB), all animals were subjected to 25 minutes of hypothermia to reduce the rectal temperatures to 18 degrees C, 60 minutes of deep hypothermic circulatory arrest (DHCA), then 10 minutes of cold perfusion with a full pump flow, and 40 minutes of rewarming. During CPB, mean arterial pressures were kept at less than 50 mm Hg. Mean extracorporeal circuit pressure (ECCP), the pressure drop of a 10 French aortic cannula, and the pulse pressure were 67+/-9, 21+/-6, and 16+/-2 mm Hg, respectively. All values are represented as mean+/-SD. No regurgitation or abnormal hemolysis has been detected during these experiments. The oxygenator had no damping effect on the quality of the pulsatility because of the dual chamber pumping mechanism. The ECCP was also significantly lower than any other known pulsatile system. We conclude that this system, with a 10 French aortic cannula and arterial filter, produces adequate pulsatility in 3 kg piglets. PMID:9952008

    The use of extracorporeal life support (ECLS) in cardiopulmonary resuscitation (CPR; ECPR) has been repeatedly published as non-randomized studies, mainly case series and case reports. The aim of this article is to support physicians, perfusionists, nurses and extracorporeal membrane oxygenation (ECMO) specialists who regularly perform ECPR or are willing to start an ECPR program by establishing standards for safe and efficient ECPR procedures. This article represents the experience and recommendations of physicians who provide ECPR routinely. Based on its survival and outcome rates, ECPR can be considered when determining the optimal treatment of patients who require CPR. The successful performance of ECLS cannulation during CPR is a life-saving measure and has been associated with improved outcome (including neurological outcome) after CPR. We summarize the general structure of an ECLS team and describe the cannulation procedure and the approaches for post-resuscitation care. The differences in hospital organizations and their regulations may result in variations of this model. PMID:26081929

    Full Text Available Background. Basic life support (BLS training with hands-on practice can improve performance during simulated cardiac arrest, although the optimal duration for BLS training is unknown. This study aimed to assess the effectiveness of various BLS training durations for acquiring cardiopulmonary resuscitation (CPR and automated external defibrillator (AED skills. Methods. We randomised 485 South Korean nonmedical college students into four levels of BLS training: level 1 (40 min, level 2 (80 min, level 3 (120 min, and level 4 (180 min. Before and after each level, the participants completed questionnaires regarding their willingness to perform CPR and use AEDs, and their psychomotor skills for CPR and AED use were assessed using a manikin with Skill-Reporter™ software. Results. There were no significant differences between levels 1 and 2, although levels 3 and 4 exhibited significant differences in the proportion of overall adequate chest compressions (p<0.001 and average chest compression depth (p=0.003. All levels exhibited a greater posttest willingness to perform CPR and use AEDs (all, p<0.001. Conclusions. Brief BLS training provided a moderate level of skill for performing CPR and using AEDs. However, high-quality skills for CPR required longer and hands-on training, particularly hands-on training with AEDs.

Very few data are available in world literature highlighting the impact of these trainings on CPR outcome. Aim: The aim of our study was to evaluate the impact of the American Heart Association (AHA-certified basic life support (BLS and advanced cardiac life support (ACLS provider course on the outcomes of CPR in our hospital. Materials and Methods : An AHA-certified BLS and ACLS provider training programme was conducted in our hospital in the first week of October 2009, in which all doctors in the code blue team and intensive care units were given training. The retrospective study was performed over an 18-month period. All in-hospital adult cardiac arrest victims in the pre-BLS/ACLS training period (January 2009 to September 2009 and the post-BLS/ACLS training period (October 2009 to June 2010 were included in the study. We compared the outcomes of CPR between these two study periods. Results: There were a total of 627 in-hospital cardiac arrests, 284 during the pre-BLS/ACLS training period and 343 during the post-BLS/ACLS training period. In the pre-BLS/ACLS training period, 52 patients (18.3% had return of spontaneous circulation, compared with 97 patients (28.3% in the post-BLS/ACLS training period (P < 0.005. Survival to hospital discharge was also significantly higher in the post-BLS/ACLS training period (67 patients, 69.1% than in the pre-BLS/ACLS training period (12 patients, 23.1% (P < 0.0001. Conclusion : Formal certified BLS and ACLS training of healthcare professionals leads to definitive improvement in the outcome of CPR.

    Clinicians and health researchers frequently encounter opportunities to rescue people. Rescue cases can generate a moral duty to aid those in peril. As such, bioethicists have leveraged a duty to rescue for a variety of purposes. Yet, despite its broad application, the duty to rescue is underanalysed. In this paper, we assess the state of theorising about the duty to rescue. There are large gaps in bioethicists' understanding of the force, scope and justification of the two most cited duties to rescue-the individual duty of easy rescue and the institutional rule of rescue. We argue that the duty of easy rescue faces unresolved challenges regarding its force and scope, and the rule of rescue is indefensible. If the duty to rescue is to help solve ethical problems, these theoretical gaps must be addressed. We identify two further conceptions of the duty to rescue that have received less attention-an institutional duty of easy rescue and the professional duty to rescue. Both provide guidance in addressing force and scope concerns and, thereby, traction in answering the outstanding problems with the duty to rescue. We conclude by proposing research priorities for developing accounts of duties to rescue in bioethics. PMID:24790055

    The treatment of children with life-threatening cardiac and cardiopulmonary failure is a large and underappreciated public health concern. We have previously shown that the CentriMag is a magnetically levitated centrifugal pump system, having the utility for treating adults and large children (1,500 utilized worldwide). We present here the PediVAS, a pump system whose design was modified from the CentriMag to meet the physiological requirements of young pediatric and neonatal patients. The PediVAS is comprised of a single-use centrifugal blood pump, reusable motor, and console, and is suitable for right ventricular assist device (RVAD), left ventricular assist device (LVAD), biventricular assist device (BVAD), or extracorporeal membrane oxygenator (ECMO) applications. It is designed to operate without bearings, seals and valves, and without regions of blood stasis, friction, or wear. The PediVAS pump is compatible with the CentriMag hardware, although the priming volume was reduced from 31 to 14 ml, and the port size reduced from 3/8 to (1/4) in. For the expected range of pediatric flow (0.3-3.0 L/min), the PediVAS exhibited superior hydraulic efficiency compared with the CentriMag. The PediVAS was evaluated in 14 pediatric animals for up to 30 days, demonstrating acceptable hydraulic function and hemocompatibility. The current results substantiate the performance and biocompatibility of the PediVAS cardiac assist system and are likely to support initiation of a US clinical trial in the future. PMID:18043164

    Full Text Available The maritime rescue, as any other legal institution related to maritime events - collision, crash, etc.- has its distinctive features. The maritime rescue may be considered as the operation that arises frommaritime collision, because, while collision stems from a breach of a negative duty necessary in maritimenavigation, i.e. of not harming the other, the maritime rescue is the implementation of positive obligationsrequired to vessel captains by the material requirements of the marine life that adds to the elements of thelegal concept which can be summed up as follows: to go to the aid of a vessel in danger, provided that thevessel does not expose itself, through this action, to a serious danger. The institution of maritime rescueencourages maritime commercial activities by the fact that, thus, there are governed such clear rights andobligations saving life at sea and shipping goods.

    In order to assist Rescue and Recovery personnel after 11 September 2001, Night Vision and Electronic Sensors Directorate was requested to collect a variety of airborne electro-optic data of the WTC site. The immediate objective was to provide FDNY with geo-rectified high-resolution and solar reflective hyperspectral data to help map the debris-field. Later data collections included calibrated MWIR data. This thermal data provided accurate temperature profiles, which could be warped to the high-resolution data. This paper will describe the assets and software used to help provide the FDNY data products, which were incorporated into their GIS database.

    1996-01-01

    The cardiopathic patient can sustain acute heart failure during pregnancy. In such cases, if open heart operation is necessary to save the patient's life, the fetus could be seriously compromised after exposure to cardiopulmonary bypass. From 1958 to 1992, 69 reports of cardiac operations during pregnancy with the aid of cardiopulmonary bypass have been published. Maternal mortality was 2.9%. Embryofetal mortality was 20.2%. Examining only the last 40 patients, maternal and embryofetal mortality were 0.0% and 12.5%, respectively. Embryofetal mortality was 24.0% when hypothermia was used, compared with 0.0% while operating in normothermia. Maternal mortality did not change. The use of hypothermia during cardiopulmonary bypass provoked uterine contractions in several patients. Hypothermia decreases O2 exchange through the placenta. Pump flow and mean arterial pressure during cardiopulmonary bypass seem to be the most important parameters that influence fetal oxygenation. We speculate that cardiac operation is not a contraindication to pregnancy prolongation. PMID:8561577

    Life sciences research in the cardiopulmonary discipline must identify possible consequences of space flight on the cardiopulmonary system, understand the mechanisms of these effects, and develop effective and operationally practical countermeasures to protect crewmembers inflight and upon return to a gravitational environment. The long-range goal of the NASA Cardiopulmonary Discipline Research Program is to foster research to better understand the acute and long-term cardiovascular and pulmonary adaptation to space and to develop physiological countermeasures to ensure crew health in space and on return to Earth. The purpose of this Discipline Plan is to provide a conceptual strategy for NASA's Life Sciences Division research and development activities in the comprehensive area of cardiopulmonary sciences. It covers the significant research areas critical to NASA's programmatic requirements for the Extended-Duration Orbiter, Space Station Freedom, and exploration mission science activities. These science activities include ground-based and flight; basic, applied, and operational; and animal and human research and development. This document summarizes the current status of the program, outlines available knowledge, establishes goals and objectives, identifies science priorities, and defines critical questions in the subdiscipline areas of both cardiovascular and pulmonary function. It contains a general plan that will be used by both NASA Headquarters Program Offices and the field centers to review and plan basic, applied, and operational (intramural and extramural) research and development activities in this area.

    1999-01-01

    Full Text Available Cardiopulmonary arrest is a medical emergency in which the lapse of time between event onset and the initiation of measures of basic and advanced support, as well as the correct care based on specific protocols for each clinical situation, constitute decisive factors for a successful therapy. Cardiopulmonary arrest care cannot be restricted to the hospital setting because of its fulminant nature. This necessitates the creation of new concepts, strategies and structures, such as the concept of life chain, cardio-pulmonary resuscitation courses for professionals who work in emergency medical services, the automated external defibrillator, the implantable cardioverter-defibrillator, and mobile intensive care units, among others. New concepts, strategies and structures motivated by new advances have also modified the treatment and improved the results of cardiopulmonary resuscitation in the hospital setting. Among them, we can cite the concept of cerebral resuscitation, the application of the life chain, the creation of the universal life support algorithm, the adjustment of drug doses, new techniques - measure of the end-tidal carbon dioxide levels and of the coronary perfusion pressure - and new drugs under research.

    Full Text Available Pectus excavatum is a chest wall deformity that produces significant cardiopulmonary disability and is typically seen in younger patients. Minimally invasive repair of pectus excavatum or Nuss procedure has become a widely accepted technique for adult and pediatric patients. Although it is carried out through a thoracoscopic approach, the procedure is associated with a number of potential intraoperative and post-operative complications. We present a case of cardiac perforation requiring emergent cardiopulmonary bypass in a 29-year-old male with Marfan syndrome and previous mitral valve repair undergoing a Nuss procedure for pectus excavatum. This case illustrates the importance of vigilance and preparation by the surgeons, anesthesia providers as well as the institution to be prepared with resources to handle the possible complications. This includes available cardiac surgical backup, perfusionist support and adequate blood product availability.

    Full Text Available Cardiac surgery carried out on cardiopulmonary bypass (CPB in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women. Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB. The CPB is associated with utero-placental hypoperfusion due to a number of factors, which may translate into low fetal cardiac output, hypoxia and even death. Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status, use of perioperative fetal monitoring, optimization of CPB, delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.

    1994-01-01

    The lung is profoundly affected by gravity. The absence of gravity (microgravity) removes the mechanical stresses acting on the lung paranchyma itself, resulting in a reduction in the deformation of the lung due to its own weight, and consequently altering the distribution of fresh gas ventilation within the lung. There are also changes in the mechanical forces acting on the rib cage and abdomen, which alters the manner in which the lung expands. The other way in which microgravity affects the lung is through the removal of the gravitationally induced hydrostatic gradients in vascular pressures, both within the lung itself, and within the entire body. The abolition of a pressure gradient within the pulmonary circulation would be expected to result in a greater degree of uniformity of blood flow within the lung, while the removal of the hydrostatic gradient within the body should result in an increase in venous return and intra-thoracic blood volume, with attendant changes in cardiac output, stroke volume, and pulmonary diffusing capacity. During the 9 day flight of Spacelab Life Sciences-1 (SLS-1) we collected pulmonary function test data on the crew of the mission. We compared the results obtained in microgravity with those obtained on the ground in both the standing and supine positions, preflight and in the week immediately following the mission. A number of the tests in the package were aimed at studying the anticipated changes in cardiopulmonary function, and we report those in this communication.

    Objective: To measure end-tidal carbon dioxide pressure (PetCO2) in preset interval in order to evaluate the efficiency of cardiopulmonary resuscitation (CPR) performed on patients in cardiopulmonary arrest, evaluate the validity of PetCO2 in predicting the mortality and finally assess the PetCO2 levels of the patients in cardiopulmonary arrest based on the initial presenting rhythm. Methods: This prospective study was conducted at the Ankara Training and Research Hospital on patients who presented with cardiopulmonary arrest. Standard ACLS (Advanced Cardiac Life Support) protocols were performed. Patients were categorized in two groups based on their rhythms as Ventricular Fibrillation and Asystole. Patients’ PetCO2 values were recorded. Results: PetCO2 levels of the Return of Spontaneous Circulation (ROSC) group in the 5th, 10th, 15th and 20th minutes were significantly higher compared to the exitus group (p<0.001). In distinguishing ROSC and exitus, PetCO2 measurements within 5-20 minute intervals showed highest performance on the 20th and lowest on the 5th minutes. Conclusion: PetCO2 values are higher in the ROSC group. During the CPR, the most reliable time for ROSC estimation according to PetCO2 values is 20th minute. None of the patients who had PetCO2 levels less than 14 mmHg survived. PMID:24639823

    1990-03-01

    The knowledge and skills surrounding the practice of cardiopulmonary resuscitation (CPR) have become essential to intensive care nurses and to nurses in general. With formalized training and refresher courses becoming more common in this country, it is evident that after relatively short periods of time the knowledge and skills acquired at such courses may be lost. While much consideration has been given to the content of both Basic and Advanced Cardiac Life Support (BCLS and ACLS) courses, relatively little attention has been paid to the educational issues surrounding CPR training. This paper explores some of these issues from the perspective of adult learning (andragogy). Research is cited from a wide range of sources to illustrate that CPR skill and knowledge deterioration is not unique to nursing, and that educational techniques exist which may improve current educational practices.

    In the aftermath of the 2003 Columbia accident, NASA removed the Hubble Space Telescope (HST) Servicing Mission 4 (SM4) from the Space Shuttle manifest. Reasons cited included concerns that the risk of flying the mission would be too high. The HST SM4 was subsequently reinstated and flown as Space Transportation System (STS)-125 because of improvements in the ascent debris environment, the development of techniques for astronauts to perform on orbit repairs to damaged thermal protection, and the development of a strategy to provide a viable crew rescue capability. However, leading up to the launch of STS-125, the viability of the HST crew rescue capability was a recurring topic. For STS-125, there was a limited amount of time available to perform a crew rescue due to limited consumables (power, oxygen, etc.) available on the Orbiter. The success of crew rescue depended upon several factors, including when a problem was identified; when and what actions, such as powering down, were begun to conserve consumables; and where the Launch on Need (LON) vehicle was in its ground processing cycle. Crew rescue success also needed to be weighed against preserving the Orbiter s ability to have a landing option in case there was a problem with the LON vehicle. This paper focuses on quantifying the HST mission loss of crew rescue capability using Shuttle historical data and various power down strategies. Results from this effort supported NASA s decision to proceed with STS-125, which was successfully completed on May 24th 2009.

    We designed the system, Rescue-MIKE, and implemented to the RoboCup Rescue Simulation System. The Rescue MIKE system aims to communicate with large numbers of relief workers and controllers working in a rescue domain. The system has an ability to report the situation of the domain like a newscaster. Our system consists of multiple agents. The system collects information from a simulated disaster scenario, and then produces a dialogue that fits to the actions of the agents in the domain. We described the design policy, implementation of our system, and Rescue-MIKE's facility. Rescue-MIKE initial version can provide aural information that helps to explain the unfolding scenarios to onlookers. We discussed the future applications of our system, including knowledge elicitation about disaster relief control methods, automated relief support systems, and public education about the dangers of large natural disasters such as earthquakes, floods or volcanic eruptions.

    2013-05-01

    Full Text Available Disaster rescue is one of the key measures of disaster reduction. The rescue process is a complex process with the characteristics of large scale, complicate structure, non-linear. It is hard to describe and analyze them with traditional methods. Based on complex adaptive theory, this paper analyzes the complex adaptation of the rescue process from seven features: aggregation, nonlinearity, mobility, diversity, tagging, internal model and building block. With the support of Repast platform, an agent-based model including rescue agents and victim agents was proposed. Moreover, two simulations with different parameters are employed to examine the feasibility of the model. As a result, the proposed model has been shown that it is efficient in dealing with the disaster rescue simulation and can provide the reference for making decisions.

  17. The rule of rescue.

    McKie, John; Richardson, Jeff

    2003-06-01

    Jonsen coined the term "Rule of Rescue"(RR) to describe the imperative people feel to rescue identifiable individuals facing avoidable death. In this paper we attempt to draw a more detailed picture of the RR, identifying its conflict with cost-effectiveness analysis, the preference it entails for identifiable over statistical lives, the shock-horror response it elicits, the preference it entails for lifesaving over non-lifesaving measures, its extension to non-life-threatening conditions, and whether it is motivated by duty or sympathy. We also consider the measurement problems it raises, and argue that quantifying the RR would probably require a two-stage procedure. In the first stage the size of the individual utility gain from a health intervention would be assessed using a technique such as the Standard Gamble or the Time Trade-Off, and in the second the social benefits arising from the RR would be quantified employing the Person Trade-Off. We also consider the normative status of the RR. We argue that it can be defended from a utilitarian point of view, on the ground that rescues increase well-being by reinforcing people's belief that they live in a community that places great value upon life. However, utilitarianism has long been criticised for failing to take sufficient account of fairness, and the case is no different here: fairness requires that we do not discriminate between individuals on morally irrelevant grounds, whereas being "identifiable" does not seem to be a morally relevant ground for discrimination.

    2001-03-15

    The aim of this project was to develop a proof-of-concept Stirling engine and heat cell for use in the mining industry, primarily for underground applications. In particular, the Stirling engine, being an external combustion engine, offers the potential to operate on stored heat in low-oxygen or inert underground atmospheres. This makes it attractive for rescue vehicles, which are required to operate in such environments. A prototype Stirling engine with power output in the 15kW range was constructed and tested. Experimental measurements showed that this output was not achieved. While the basic thermodynamic principles of the design were valid, achieved output was well below the required value. The conclusion is that, because of the lack of commercial Stirling cycle-based products and the difficulty experienced in this project in overcoming the problem of high temperature seal implementation to produce a working prototype, the short term potential of the Stirling engine for mine rescue applications is limited.

    Helicopter emergency medical service (HEMS) have become a main part of prehospital emergency medical services over the last 40 years. Recently, an ongoing discussion about financial shortage and personal shortcomings question the role of cost-intensive air rescue. Thus, the value of HEMS must be examined and discussed appropriately. Since the number of physician-staffed ground ambulances may decrease due to the limited availability of qualified physicians, HEMS may fill the gap. In addition patient transfer to specialized hospitals will require an increasing number of air transports in order to minimize prehospital time. The higher risk ratio for HEMS missions when compared with ground rescue requires a rigorous quality management system. When it comes to missions in remote and exposed areas, the scope of medical treatment must be adjusted to the individual situation. Medical competence is key in order to balance guideline compliant or maximal care versus optimal care characterized as a mission-specific, individualized emergency care concept. Although, medical decision making and treatment is typically based on the best scientific evidence, personal skills, competence, and the mission scenario will determine the scope of interventions suitable to improve outcome. Thus, the profile of requirements for the HEMS medical crew is high. PMID:24618925

    Occipitally joined craniopagus Siamese twins were separated with the use of cardiopulmonary bypass and hypothermic circulatory arrest. The 7-month-old infants shared a large sagittal venous sinus that precluded conventional neurosurgical approach because of risk of exsanguination and air embolism. After craniotomy and preliminary exposure of the sinus, each twin underwent sternotomy and total cardiopulmonary bypass with deep hypothermia. Hypothermic circulatory arrest allowed safe division and subsequent reconstruction of the sinus remnants. Several unusual problems were encountered, including transfusion of a large blood volume from one extracorporeal circuit to the other through the common venous sinus, deleterious warming of the exposed brain during circulatory arrest, and thrombosis of both pump oxygenators. Both infants survived, although recovery was complicated in each by neurologic injury, cranial wound infection, and hydrocephalus. This case demonstrates the valuable supportive role of cardiopulmonary bypass and hypothermic circulatory arrest in the management of complex surgical problems of otherwise inoperable patients.

    Morris, Richard W; Pybus, David A

    2007-12-01

    In this paper we describe a high-fidelity perfusion simulation system intended for use in the training and continuing education of perfusionists. The system comprises a hydraulic simulator, an electronic interface unit and a controlling computer with associated real-time computer models. It is designed for use within an actual operating theatre, or within a specialized simulation facility. The hydraulic simulator can be positioned on an operating table and physically connected to the circuit of the institutional heart-lung machine. The institutional monitoring system is used to display the arterial and central venous pressures, the ECG and the nasopharyngeal temperature using appropriate connections. The simulator is able to reproduce the full spectrum of normal and abnormal events that may present during the course of cardiopulmonary bypass. The system incorporates a sophisticated blood gas model that accurately predicts the behavior of a modern, hollow-fiber oxygenator. Output from this model is displayed in the manner of an in-line blood gas electrode and is updated every 500 msecs. The perfusionist is able to administer a wide variety of drugs during a simulation session including: vasoconstrictors (metaraminol, epinephrine and phenylephrine), a vasodilator (sodium nitroprusside), chronotropes (epinephrine and atropine), an inotrope (epinephrine) and modifiers of coagulation (heparin and protamine). Each drug has a pharmacokinetic profile based on a three-compartment model plus an effect compartment. The simulation system has potential roles in the skill training of perfusionists, the development of crisis management protocols, the certification and accreditation of perfusionists and the evaluation of new perfusion equipment and/or techniques.

    Although there are known detrimental effects of obesity on the heart and lungs, few data exist showing obesity as risk factor for cardiopulmonary disorders in dogs and cats. It is probable that increased abdominal fat is detrimental as it is in humans, and there is evidence of negative effects of increased intrathoracic fat. As well as physical effects of fat, increased inflammatory mediators and neurohormonal effects of obesity likely contribute to cardiopulmonary disorders. Weight loss in overweight individuals improves cardiac parameters and exercise tolerance. Obesity in patients with obstructive airway disorders is recognized to increase disease severity.

    Background The use of extracorporeal life support (ECLS) in the setting of cardiopulmonary resuscitation (CPR) has shown improved outcomes compared with conventional CPR. The aim of this study was to determine factors predictive of survival in extracorporeal CPR (E-CPR). Methods Consecutive 85 adult patients (median age, 59 years; range, 18 to 85 years; 56 males) who underwent E-CPR from May 2005 to December 2012 were evaluated. Results Causes of arrest were cardiogenic in 62 patients (72.9%), septic in 18 patients (21.2%), and hypovolemic in 3 patients (3.5%), while the etiology was not specified in 2 patients (2.4%). The survival rate in patients with septic etiology was significantly poorer compared with those with another etiology (0% vs. 24.6%, p=0.008). Septic etiology (hazard ratio [HR], 2.84; 95% confidence interval [CI], 1.49 to 5.44; p=0.002) and the interval between arrest and ECLS initiation (HR, 1.05 by 10 minutes increment; 95% CI, 1.02 to 1.09; p=0.005) were independent risk factors for mortality. When the predictive value of the E-CPR timing for in-hospital mortality was assessed using the receiver operating characteristic curve method, the greatest accuracy was obtained at a cutoff of 60.5 minutes (area under the curve, 0.67; 95% CI, 0.54 to 0.80; p=0.032) with 47.8% sensitivity and 88.9% specificity. The survival rate was significantly different according to the cutoff of 60.5 minutes (p=0.001). Conclusion These results indicate that efforts should be made to minimize the time between arrest and ECLS application, optimally within 60 minutes. In addition, E-CPR in patients with septic etiology showed grave outcomes, suggesting it to be of questionable benefit in these patients. PMID:27525236

    Emboli in the brain microvasculature may inhibit brain activity during cardiopulmonary bypass. Such hypothetical blockade, if confirmed, may be responsible for the reduction of cerebral metabolic rate for glucose observed in animals subjected to cardiopulmonary bypass. In previous studies of cerebral blood flow during bypass, brain microcirculation was not evaluated. In the present study in animals (pigs), reduction of the number of perfused capillaries was estimated by measurements of the capillary diffusion capacity for hydrophilic tracers of low permeability. Capillary diffusion capacity, cerebral blood flow, and cerebral metabolic rate for glucose were measured simultaneously by the integral method, different tracers being used with different circulation times. In eight animals subjected to normothermic cardiopulmonary bypass, and seven subjected to hypothermic bypass, cerebral blood flow, cerebral metabolic rate for glucose, and capillary diffusion capacity decreased significantly: cerebral blood flow from 63 to 43 ml/100 gm/min in normothermia and to 34 ml/100 gm/min in hypothermia and cerebral metabolic rate for glucose from 43.0 to 23.0 mumol/100 gm/min in normothermia and to 14.1 mumol/100 gm/min in hypothermia. The capillary diffusion capacity declined markedly from 0.15 to 0.03 ml/100 gm/min in normothermia but only to 0.08 ml/100 gm/min in hypothermia. We conclude that the decrease of cerebral metabolic rate for glucose during normothermic cardiopulmonary bypass is caused by interruption of blood flow through a part of the capillary bed, possibly by microemboli, and that cerebral blood flow is an inadequate indicator of capillary blood flow. Further studies must clarify why normal microvascular function appears to be preserved during hypothermic cardiopulmonary bypass.

    2004-11-01

    Circuit models have been used extensively in physiology to describe cardiopulmonary function. Such models are being used in the DARPA Virtual Soldier (VS) Project* to predict the response to injury or physiological stress. The most complex model consists of systemic circulation, pulmonary circulation, and a four-chamber heart sub-model. This model also includes baroreceptor feedback, airway mechanics, gas exchange, and pleural pressure influence on the circulation. As part of the VS Project, Oak Ridge National Laboratory has been evaluating various cardiopulmonary circuit models for predicting the effects of injury to the heart. We describe, from a physicist's perspective, the concept of building circuit models, discuss both unstressed and stressed models, and show how the stressed models are used to predict effects of specific wounds. *This work was supported by a grant from the DARPA, executed by the U.S. Army Medical Research and Materiel Command/TATRC Cooperative Agreement, Contract # W81XWH-04-2-0012.

  16. Do Radiologists Want/Need Training in Cardiopulmonary Resuscitation?

    International Nuclear Information System (INIS)

    Purpose: Prompt and effective cardiopulmonary resuscitation (CPR) decreases morbidity and mortality following cardiopulmonary arrest. Radiologists are frequently confronted with severely ill patients, who may deteriorate at any time. Furthermore, they have to be aware of life-threatening reactions towards contrast media. This study was designed to assess experience and self-estimation of German-speaking radiologists in CPR and cardiac defibrillation (CD). Material and Methods: 650 German-speaking radiologists were audited by a specially designed questionnaire, which was sent via e-mail. The answers were expected to be re-mailed within a 2-month period. Results: The response rate was 12.6%. 72.8% of the responders had performed at least 1 CPR (range 9.5 ± 13.1) and 37% at least 1 CD. 67.9% had had opportunities to attend training courses, which had been utilized by 41.8% of them. The last training of the responders was more than 2 years ago in 69.2% and more than 5 years ago in 37%. Of all responders 75.6% expressed the need for further education. Conclusion: The small response rate indicates the small importance of CPR in the subpopulation surveyed. The vast majority of the responders, however, showed interest in basic and advanced life support and advocated regular updates. It seems reasonable that radiological Dept. themselves should organize courses in order to cope with their specific situations

    Anaphylactoid reactions to iodinated contrast media can cause life-threatening events and even death. A 44-year-old woman presented with cardiopulmonary arrest (CPA) immediately following the administration of nonionic iodinated contrast media for an intravenous pyelography. Her cardiac rhythm during CPA was asystole. She was successfully resuscitated by the radiologists supported by paged emergency physicians using the prompt intravenous administration of 1 mg of epinephrine. Neither laryngeal edema nor bronchial spasm was observed during the course of treatment, and she was discharged on the 4th day without any complications. The patient did not have a history of allergy, but had experienced a myocardial infarction and aortitis. She had undergone 11 angiographies and had been taking a beta-adrenergic receptor antagonist. Planned emergency medical backup is advisable to ensure resuscitation in the event of an anaphylactoid reaction to the use of contrast media in-hospital settings. PMID:12009227

    Full Text Available Objective: To evaluate the effect of hemofiltration during cardiopulmonary bypass on lactate level in adult patients who underwent cardiac surgery. Design: An observational study. Setting: Prince Sultan cardiac center, Riyadh, Saudi Arabia. Participants: The study included 283 patients classified into two groups: Hemofiltration group (n=138, hemofiltration was done during CPB. Control group (n = 145, patients without hemofiltration. Interventions: Hemofiltration during cardiopulmonary bypass. Measurements and Main Results: Monitors included hematocrit, lactate levels, mixed venous oxygen saturation, amount of fluid removal during hemofiltration and urine output. The lactate elevated in group H than group C (P < 0.05, and the PH showed metabolic acidosis in group H (P < 0.05. The mixed venous oxygen saturation decreased in group H than group C (P < 0.05. The number of transfused packed red blood cells was lower in group H than group C (P < 0.05. The hematocrit was higher in group H than group C (P < 0.05. The urine output was lower in group H than group C (P < 0.05. Conclusions: Hemofiltration during cardiopulmonary bypass leads to hemoconcentration, elevated lactate level and increased inotropic support. There are some recommendations for hemofiltration: First; Hemofiltration should be limited for patients with impaired renal function, positive fluid balance, reduced response to diuretics or prolonged bypass time more than 2 hours. Second; Minimal amount of fluids should be administered to maintain adequate cardiac output and reduction of priming volumes is preferable to maintain controlled hemodilution. Third; it should be done before weaning of or after cardiopulmonary bypass and not during the whole time of cardiopulmonary bypass.

  3. Joseph Conrad's tormented Rescue (fantasy).

    Science.gov (United States)

    Freedman, William

    2014-02-01

    Joseph Conrad was a notoriously tormented writer for whom the creative act was often a punishment severe enough to drive him into paralyzing depressions that delayed the completion of his novels, sometimes for years. By far the most agonizing of these projects was The Rescue, a novel he began in 1898, abandoned a year later, tried unsuccessfully to continue several times over the next two decades, but was only able to resume in 1918 and to complete, after another tortured two-year struggle, in 1920. An explanation for this incapacity, that is powerfully suggested by the novel's evocative title and perhaps unintentionally ironic subtitle (A Romance of the Shallows) has not yet been explored. Using Freud's 1910 essay on the rescue fantasy, "Contributions to the Psychology of Love: A Special Type of Choice of Object Made by Men," and Emanuel Berman's instructive revision and expansion of the concept in his 2003 American Imago essay, "Ferenczi, Rescue, and Utopia," I argue that a substantial explanation for Conrad's tormented history with The Rescue is ascribable to its quite remarkably faithful treatment of a rescue fantasy with deep and disabling resonance for its author. More specifically, the difficulty was compounded by the novel's dramatization of the soul-crushing conflict between two such fantasies: one in the service of the masculine ideal of unflinching dedication to a heroic purpose, the other promising satisfaction to the equally potent demands of emotional and sexual desire. Features of Conrad's narrative fit so tightly and consistently with the theory as Freud (and Abraham) proposed and as Berman elaborated it that The Rescue offers itself as one of those rare and reinforcing instances wherein the literary text seems to validate the psychoanalytic theory at least as persuasively as the theory "understands" the text.

    In the 43 years since it was first described, cardiopulmonary resuscitation (CPR) has grown from an obscure medical theory to a basic first aid skill taught to adults and is now the near-universal technique used in CPR instruction. This article provides insight into the history of CPR. We explore the phenomenon of sudden cardiac arrest, the historical roots of CPR, current practice data and recommendations, and the society's role in the development of this life-saving technique. We conclude with a review of CPR's economic impact on the healthcare system and the ethical and policy issues surrounding CPR. PMID:17179837

  16. Toward a behavioral ecology of rescue behavior.

    2013-01-01

    Although the study of helping behavior has revolutionized the field of behavioral ecology, scientific examination of rescue behavior remains extremely rare, except perhaps in ants, having been described as early as 1874. Nonetheless, recent work in our laboratories has revealed several new patterns of rescue behavior that appear to be much more complex than previously studied forms. This precisely-directed rescue behavior bears a remarkable resemblance to what has been labeled empathy in rats, and thus raises numerous philosophical and theoretical questions: How should rescue behavior (or empathy) be defined? What distinguishes rescue from other forms of altruism? In what ways is rescue behavior in ants different from, and similar to, rescue in other non-human animals? What selection pressures dictate its appearance? In this paper, we review our own experimental studies of rescue in both laboratory and field, which, taken together, begin to reveal some of the behavioral ecological conditions that likely have given rise to rescue behavior in ants. Against this background, we also address important theoretical questions involving rescue, including those outlined above. In this way, we hope not only to encourage further experimental analysis of rescue behavior, but also to highlight important similarities and differences in very distant taxa. PMID:23864298

  17. Rescuing the Regent Theatre

    Full Text Available Melbourne’s Regent and Plaza theatres opened in Collins Street in 1929. For more than forty years, these grand picture palaces were among Melbourne’s most treasured cinemas, favourites together with the Capitol Theatre in Swanston Street and the State Theatre in Flinders Street. Often called ‘palaces of dreams’, they were part of a glamorous entertainment era, when a night out at the movies was an event, and an afternoon matinee was a treat. Not even the Regent’s two-year closure, as a result of the fire that destroyed the auditorium in 1945, could dampen the enthusiasm of its Melbourne audiences. By the 1960s, however, the grand picture palaces were no longer in vogue and were becoming uneconomical to run. The State Theatre closed in 1962 and was later converted into two theatres. The Capitol closed in 1964, but when it re-opened eighteen months later a shopping arcade had been built in the lower part of the auditorium. After investigating the option of converting the Regent into two theatres, its owner, Hoyts, opted to develop a smaller multi-cinema complex in Bourke Street instead. The company sold the Regent and Plaza theatres to the City of Melbourne in 1969 and in 1970 the doors of the Regent and Plaza closed for what many people thought was the last time. Melbourne City Council bought the Regent and Plaza in order to control development around the site of the proposed City Square on the corner of Swanston and Collins Streets. The theatres seemed destined to fall victim to the wrecker’s ball. But if the 1960s was the decade of development, the 1970s was the decade of preservation. Protests against the demolition of historic buildings occurred around Australia, often with the controversial support of the building unions. The architectural profession debated the issues of preservation versus development of dynamic modern buildings. Both the State and Federal Governments were forced to introduce legislation to protect the nation

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    Background Coma after cardiopulmonary resuscitation (CPR) is commonly seen in daily clinical practice. How to objectively evaluate brain function after CPR is essential to the following treatment. Coma patients after CPR had been studied prospectively at the Neuro-Intensive Care Unit of Xuanwu Hospital since 2002. In this study, we focused on the topic of how to evaluate the severity of coma after CPR .Methods From April 2002 to November 2004, patients in coma 24 hours after CPR were monitored, the evaluation methods included Glasgow coma score (GCS),brain stem reflection, and spinal reflection. Laboratory evaluation included electroencephalography (EEG),brainstem auditory evoked potential (BAEP), short latency somatosensory evoked potential (SLSEP), and transcranial Doppler (TCD) .Results Twenty-four of 35 patients(68.57%)were in deep coma. The GCS was 3 except for 2 patients;EEG was evaluated not less than grade Ⅳ except for 4 patients, BAEP was evaluated as grade Ⅲ except for 3 patients, and SLSEP was evaluated as grade Ⅲ except for 1 patient.Twenty-four patients died within 1 month and 11 of them(45.83%)were determined as brain death. Glasgow outcome score (GOS) was evaluated as grade Ⅰ. Eleven of the 35 patients survived and their consciousness changed from deep coma to coma vigil. EEG was evaluated as gradeⅠin 5 patients, BAEP and SLSEP were evaluated as grade Ⅰ in 3 patients, and GOS was all evaluated as grade Ⅱ among the 11 patients.Two patients(18.18%)regained consciousness in 35 and 90 days after cardiopulmonary resuscitation and GOS was evaluated as grade Ⅳ and Ⅲ, respectively.Conclusion Combined or continuous evaluation of clinical examinations and laboratory tests can accurately and objectively determine brain function after CPR.

  1. Capnography during cardiopulmonary resuscitation: Current evidence and future directions

    2014-01-01

    Full Text Available Capnography continues to be an important tool in measuring expired carbon dioxide (CO 2 . Most recent Advanced Cardiac Life Support (ACLS guidelines now recommend using capnography to ascertain the effectiveness of chest compressions and duration of cardiopulmonary resuscitation (CPR. Based on an extensive review of available published literature, we selected all available peer-reviewed research investigations and case reports. Available evidence suggests that there is significant correlation between partial pressure of end-tidal CO 2 (PETCO 2 and cardiac output that can indicate the return of spontaneous circulation (ROSC. Additional evidence favoring the use of capnography during CPR includes definitive proof of correct placement of the endotracheal tube and possible prediction of patient survival following cardiac arrest, although the latter will require further investigations. There is emerging evidence that PETCO 2 values can guide the initiation of extracorporeal life support (ECLS in refractory cardiac arrest (RCA. There is also increasing recognition of the value of capnography in intensive care settings in intubated patients. Future directions include determining the outcomes based on capnography waveforms PETCO 2 values and determining a reasonable duration of CPR. In the future, given increasing use of capnography during CPR large databases can be analyzed to predict outcomes.

    Electrical failure during cardiopulmonary bypass is a crisis situation for the cardiac surgical team. Fortunately, it has a low incidence with low morbidity and mortality rates. Notwithstanding, institutional preventative and management measures should be taken. Here, we report a case of electrical failure during cardiopulmonary bypass, which was successfully managed during the surgery, allowing the patient to recover uneventfully. These unwanted complications can only be managed by promoting awareness and putting in place strategies against them. PMID:27516788

    2012-04-01

    Climate science as a whole as well as reanalyses as a special case can significantly profit from the recovery, imaging and digitisation of historical observations. The importance of this fact is reflected in large, global data rescue projects and initiatives such as the Atmospheric Circulation Reconstructions over the Earth (ACRE, www.met-acre.org) or the EU FP7 ERA-CLIM project (www.era-clim.eu). From the time before 1957, there are still large amounts of surface data e.g. from former colonies and from overseas territories of European countries )e.g. Portugal, France and Germany) that need to be rescued. Also in case of the very early upper-air observations before the 1930s, even Europe and North America still hold an important quantity of data to be recovered in digital form. Here, we present the web platform "Data Rescue @ Home" (www.data-rescue-at-home.org), which has been developed at ETH Zurich and Oeschger Centre for Climate Change Research, and which has been designed to take advantage of the voluntary assistance of the thousands of people on the web who are interested in climate or old weather data. On the website, these volunteers can enter meteorological data shown on digital images into entry masks that resemble the original. By registering, the users get access to their personal digitisation statistics and help optimising the project. At the moment, 4 digitisation projects are online: One project is dealing with German upper-air data from the Second World War period. In a second project, station data from Tulagi (Solomon Islands) is being digitised. Finally, two collaborative projects have been included: One in cooperation with the Instituto Dom Luiz (Univ. Lisbon, Portugal), where Portuguese station data from Angra (Azores) is digitised, and a further one in cooperation with the German Meteorological Service (DWD), in which precipitation data from former German colonies is being digitised. On our poster, we will report on the status of the projects

  11. Family presence during cardiopulmonary resuscitation: who should decide?

    Science.gov (United States)

    Lederman, Zohar; Garasic, Mirko; Piperberg, Michelle

    2014-05-01

    Whether to allow the presence of family members during cardiopulmonary resuscitation (CPR) has been a highly contentious topic in recent years. Even though a great deal of evidence and professional guidelines support the option of family presence during resuscitation (FPDR), many healthcare professionals still oppose it. One of the main arguments espoused by the latter is that family members should not be allowed for the sake of the patient's best interests, whether it is to increase his chances of survival, respect his privacy or leave his family with a last positive impression of him. In this paper, we examine the issue of FPDR from the patient's point of view. Since the patient requires CPR, he is invariably unconscious and therefore incompetent. We discuss the Autonomy Principle and the Three-Tiered process for surrogate decision making, as well as the Beneficence Principle and show that these are limited in providing us with an adequate tool for decision making in this particular case. Rather, we rely on a novel principle (or, rather, a novel specification of an existing principle) and a novel integrated model for surrogate decision making. We show that this model is more satisfactory in taking the patient's true wishes under consideration and encourages a joint decision making process by all parties involved. PMID:23557910

    2015-10-01

    Full Text Available BACKGROUND: After cardiac surgery acute kidney injury (AKI is a common and serious condition carrying significant costs and is independently associated with increased morbidity and mortality. During cardiopulmonary bypass (CPB surgery, modifiable factors may contri bute to post - operative AKI. Their prevention might be a potential target for nephroprotection and any other morbidity after cardiac surgery. METHODS AND MATERIAL : The objective of the present study was to identify and determine whether intraoperative hypot ension or any other cofactor are independent risk factors for postoperative AKI defined by the RIFLE (renal Risk, Injury, Failure, Loss of renal function and End - stage renal disease. On basis of this patients were divided into two groups according to rise in serum creatinine >0.3 mg/dl till 72 hrs postoperatively. Group B patients have developed AKI (n=34 and the remaining patients were in Group A. RESULT : In our study we have found that mean arterial pressure during CPB were less in group B patients compare to group A patients which was statistically significant (p<0.001. And in this group ICU stay and mortality rate were also high compare to group A pati ent who had not developed AKI. CONCLUSION: Lower MAP during CPB is associated with development of postoperative renal derangement, leads to increase ICU stay and mortality. Larger studies are required to further support the evidence

  13. Outcome of cardiopulmonary resuscitation - predictors of survival

    International Nuclear Information System (INIS)

    To assess the outcomes of patients undergoing cardiopulmonary resuscitation (CPR). Data were collected retrospectively of all adult patients who underwent CPR. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from hospital. Factors associated with survival were evaluated using logistic regression analysis. Of the 159 patients included, 55 (35%) were alive at the end of CPR and 17 (11%) were discharged alive from the hospital. At the end of CPR, univariate logistic regression analysis found the following factors associated with survival: cardiac arrest within hospital as compared to outside the hospital (odds ratio = 2.8, 95% CI = 1.27-6.20, p-value = 0.01), both cardiac and pulmonary arrest as compared to either cardiac or pulmonary arrest (odds ratio = 0.37, 95% CI = 0.19- 0.73, p-value = 0.004), asystole as cardiac rhythm at presentation (odds ratio = 0.47, 95% CI = 0.24-0.93, p-value = 0.03), and total atropine dose given during CPR (odds ratio = 0.78, 95% CI = 0.62-0.97, p-value = 0.02). In multivariate logistic regression, cardiac arrest within hospital (odds ratio = 2.52, 95% CI = 1.06-5.99, p-value = 0.04) and both cardiac and pulmonary arrest as compared to cardiac or pulmonary arrest (odds ratio = 0.44, 95% CI = 0.21-0.91, p-value = 0.03) were associated with survival at the end of CPR. At the time of discharge from hospital, univariate logistic regression analysis found following factors that were associated with survival: cardiac arrest within hospital (odds ratio = 8.4, 95% CI = 1.09-65.64, p-value = 0.04), duration of CPR (odds ratio = 0.91, 95% CI = 0.85-0.96, p-value = 0.001), and total atropine dose given during CPR (odds ratio = 0.68, 95% CI = 0.47-0.99, p-value = 0.05). In multivariate logistic regression analysis cardiac arrest within hospital (odds ratio 8.69, 95% CI = 1.01-74.6, p-value = 0.05) and duration of CPR (odds ratio 0.92, 95% CI = 0.87-0.98, p-value = 0.01) were associated with survival at

    2016-08-01

    Exercise intolerance, indicated by dyspnea and fatigue during exertion, is a cardinal manifestation of heart failure (HF). Cardiopulmonary exercise testing (CPET) precisely defines maximum exercise capacity through measurement of peak oxygen uptake (VO2). Peak VO2 values have a critical role in informing patient selection for advanced HF interventions such as heart transplantation and ventricular assist devices. Oxygen uptake and ventilatory patterns obtained during the submaximal portion of CPET are also valuable to recognize because of their ease of ascertainment during low-level exercise, relevance to ability to perform activities of daily living, independence from volitional effort, and strong relationship to prognosis in HF. The ability of peak VO2 and other CPET variables to be measured reproducibly and to accurately reflect HF severity is increasingly recognized and endorsed by scientific statements. Integration of CPET with invasive hemodynamic monitoring and cardiac imaging during exercise provides comprehensive characterization of multisystem reserve capacity that can inform prognosis and the need for cardiac interventions. Here, we review both practical aspects of conducting CPETs in patients with HF for clinical and research purposes as well as interpretation of gas exchange patterns across the spectrum of preclinical HF to advanced HF.

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

  17. Cardiopulmonary effects of intermittent mandatory ventilation.

    Douglas, M E; Downs, J B

    1980-01-01

    IMV is a combination of spontaneous and mechanical ventilation. For numerous reasons, IMV is potentially more advantageous than conventional techniques. By maintaining spontaneous breathing, mechanical augmentation can be titrated to adjust alveolar minute ventilation levels to normal, thereby decreasing the incidence of respiratory alkalemia. There are major differences between the cardiopulmonary effects of IMV and conventional mechanical ventilation. Spontaneous inspiration decreases Ppl and results in better distribution of inspired gas, a better V/Q, and less physiological dead space. In addition, transmural filling pressures, venous return, and cardiac output are more normal than during conventional mechanical ventilation. Maintenance of spontaneous ventilation lowers mean Paw and pulmonary vascular resistance. If venous admixture occurs, it can be minimized by titrating PEEP. Thus, more effective therapy for hypoxemia is possible. If spontaneous breathing is to persist and be efective, work-of-breathing must be minimized. This can be accomplished best when a continuous flow of gas provides optimal CPAP to maintain FRC and to minimize the effects of decreased compliance without depressing cardiac function.

    Nagaoka, Shunji; Eno, Yuko; Ohira, Yoshinobu

    Cardio-pulmonary reflex, which our cardiac activity is synchronized to the respiration by autonomic nervous system regulation, is called as "respiratory sinus arrhythmia" and commonly found in adult. The physiological function of the espiratory sinus arrhythmia is considered to maximize the gas exchange during respiration cycle. This respiration induced heart rate variability (RHRV) is only found in mammals and avian showing a remarkable postnatal development, whereas no RHRV in aquatic species such as fish or amphibian. To elucidate our hypothesis that gravity exposure may plays a key role in the postnatal development of RHRV as well as its evolutional origin in these ground animals, we have studied effects of hypergravity (2G) on the postnatal development of RHRV using rat. Pregnant Wister rats were kept in centrifugal cages system for 38 days from 6th days of pregnant mother to have neonates until 23 days old. Electrocardiograph was recorded from the neonates in 2 to 23 days old in 2G group with simultaneous control (1G) group. The RHRV analysis was performed by calculating a component of Fourier power spectral coincide with the respiration frequency. In both groups, averaged resting heart rate gradually increase from 2 to 23 days old. When comparing the heart rate between the two groups, the 2G group indicated significantly lower (240± 8 bpm) than 1G control (326±21 bpm, p¡0.001) in 2 days old, where as no significance in 23 days old. The RHRV of 2 days old neonates in both groups indicated very small magnitude but significantly lower in 2G group than 1G control (p¡0.01). The RHRV gradually increase during the first 2 weeks and then rapid increased to reached 45 fold of magnitude in 1G control, whereas 69 fold in 2G group. The results strongly suggested that the postnatal innervation from respiration to cardiovascular centers was gravity dependent.

    Full Text Available Abstract Background Acute posthypoxic myoclonus (PHM can occur in patients admitted after cardiopulmonary resuscitation (CPR and is considered to have a poor prognosis. The origin can be cortical and/or subcortical and this might be an important determinant for treatment options and prognosis. The aim of the study was to investigate whether acute PHM originates from cortical or subcortical structures, using somatosensory evoked potential (SEP and electroencephalogram (EEG. Methods Patients with acute PHM (focal myoclonus or status myoclonus within 72 hours after CPR were retrospectively selected from a multicenter cohort study. All patients were treated with hypothermia. Criteria for cortical origin of the myoclonus were: giant SEP potentials; or epileptic activity, status epilepticus, or generalized periodic discharges on the EEG (no back-averaging was used. Good outcome was defined as good recovery or moderate disability after 6 months. Results Acute PHM was reported in 79/391 patients (20%. SEPs were available in 51/79 patients and in 27 of them (53% N20 potentials were present. Giant potentials were seen in 3 patients. EEGs were available in 36/79 patients with 23/36 (64% patients fulfilling criteria for a cortical origin. Nine patients (12% had a good outcome. A broad variety of drugs was used for treatment. Conclusions The results of this study show that acute PHM originates from subcortical, as well as cortical structures. Outcome of patients admitted after CPR who develop acute PHM in this cohort was better than previously reported in literature. The broad variety of drugs used for treatment shows the existing uncertainty about optimal treatment.

    Hantavirus cardiopulmonary syndrome has a high mortality rate, and early connection to extracorporeal membrane oxygenation has been suggested to improve outcomes. We report the case of a patient with demonstrated Hantavirus cardiopulmonary syndrome and refractory shock who fulfilled the criteria for extracorporeal membrane oxygenation and responded successfully to high volume continuous hemofiltration. The implementation of high volume continuous hemofiltration along with protective ventilation reversed the shock within a few hours and may have prompted recovery. In patients with Hantavirus cardiopulmonary syndrome, a short course of high volume continuous hemofiltration may help differentiate patients who can be treated with conventional intensive care unit management from those who will require more complex therapies, such as extracorporeal membrane oxygenation.

  12. Follow-up of relapsed B-cell lymphoma patients treated with iodine-131-labeled anti-CD20 antibody and autologous stem-cell rescue

    International Nuclear Information System (INIS)

    Radioimmunotherapy (RIT) is a promising treatment approach for B-cell lymphomas. This is our first opportunity to report long-term follow-up data and late toxicities in 29 patients treated with myeloablative doses of iodine-131-anti-CD20 antibody (anti-B1) and autologous stem-cell rescue. PATIENTS AND METHODS: Trace-labeled biodistribution studies first determined the ability to deliver higher absorbed radiation doses to tumor sites than to lung, liver, or kidney at varying amounts of anti-B1 protein (0.35, 1.7, or 7 mg/kg). Twenty- nine patients received therapeutic infusions of single-agent (131)I- anti-B1, given at the protein dose found optimal in the biodistribution study, labeled with amounts of (131)I (280 to 785 mCi[10.4 to 29.0 GBq]) calculated to deliver specific absorbed radiation doses to the normal organs, followed by autologous stem-cell support. RESULTS: Major responses occurred in 25 patients (86%), with 23 complete responses (CRs; 79%). The nonhematopoietic do se-limiting toxicity was reversible cardiopulmonary insufficiency, which occurred in two patients at RIT doses that delivered > or = 27 Gy to the lungs. With a median follow-up time of 42 months, the estimated overall and progression-free survival rates are 68% and 42%, respectively. Currently, 14 of 29 patients remain in unmaintained remissions that range from 27+ to 87+ months after RIT. Late toxicities have been uncommon except for elevated thyroid-stimulating hormone (TSH) levels found in approximately 60% of the subjects. Two patients developed second malignancies, but none have developed myelodysplasia (MDS). CONCLUSION: Myeloablative (131)I-anti- B1 RIT is relatively well tolerated when given with autologous stem- cell support and often results in prolonged remission durations with few late toxicities

    We conducted a survey of equipment in medical backpacks for mountain rescuers and mountain emergency physicians. The aim was to investigate whether there are standards for medical equipment in mountain rescue organizations associated with the International Commission for Mountain Emergency Medicine (ICAR MEDCOM). A questionnaire was completed by 18 member organizations from 14 countries. Backpacks for first responders are well equipped to manage trauma, but deficiencies in equipment to treat medical emergencies were found. Paramedic and physicians' backpacks were well equipped to provide advanced life support and contained suitable drugs. We recommend that medical backpacks should be equipped in accordance with national laws, the medical emergencies in a given region, and take into account the climate, geography, medical training of rescuers, and funding of the organization. Automated external defibrillator provision should be improved. The effects of temperature on the drugs and equipment should be considered. Standards for training in the use and maintenance of medical tools should be enforced. First responders and physicians should only use familiar tools and drugs. PMID:22206560

    A wide range of pharmacological, surgical, and mechanical pump approaches have been studied to attenuate the systemic inflammatory response to cardiopulmonary bypass, yet no systematically based review exists to cover the scope of anti-inflammatory interventions deployed. We therefore conducted an evidence-based review to capture "self-identified" anti-inflammatory interventions among adult cardiopulmonary bypass procedures. To be included, trials had to measure at least one inflammatory mediator and one clinical outcome, specified in the "Outcomes 2010" consensus statement. Ninety-eight papers satisfied inclusion criteria and formed the basis of the review. The review identified 33 different interventions and approaches to attenuate the systemic inflammatory response. However, only a minority of papers (35 of 98 [35.7%]) demonstrated any clinical improvement to one or more of the predefined outcome measures (most frequently myocardial protection or length of intensive care unit stay). No single intervention was supported by strong level A evidence (multiple randomized controlled trials [RCTs] or meta-analysis) for clinical benefit. Interventions at level A evidence included off-pump surgery, minimized circuits, biocompatible circuit coatings, leukocyte filtration, complement C5 inhibition, preoperative aspirin, and corticosteroid prophylaxis. Interventions at level B evidence (single RCT) for minimizing inflammation included nitric oxide donors, C1 esterase inhibition, neutrophil elastase inhibition, propofol, propionyl-L-carnitine, and intensive insulin therapy. A secondary analysis revealed that suppression of at least one inflammatory marker was necessary but not sufficient to confer clinical benefit. The most effective interventions were those that targeted multiple inflammatory pathways. These observations are consistent with a "multiple hit" hypothesis, whereby clinically effective suppression of the systemic inflammatory response requires hitting multiple

  2. Predicting postoperative cardiopulmonary complications by a test of stair climbing

    International Nuclear Information System (INIS)

    Objective: To assess whether a test of stair climbing ability could be used to predict the risk of developing postoperative cardiopulmonary complications in patients undergoing general anesthesia. Design: Cohort study Place and Duration of Study: The Aga Khan University Hospital, Karachi. The duration of the study was from December 2003 to December 2004. Patients and Methods: This study was carried out on consecutive, adult patients presenting for elective thoracic or abdominal surgery under general anesthesia. Pre-operatively, patients were asked to climb a standard staircase. Number of steps climbed was recorded. Those unable to climb stairs due to debilitation cardiac, pulmonary or rheumatologic disease were categorized as 0 stairs climbed. Outcome variables were postoperative cardiopulmonary complications for mortality. Period of follow-up was until hospital discharge. Results: Seventy-eight patients were enrolled; 59 (75.6%) climbed > 1 flight of stairs, 19 (24.3%) climbed 1 flight and 40% in those patients who climbed < 1 flight. The group that climbed < 1 flight tended to have complications associated with poor reserves of the cardiopulmonary systems; i.e. pulmonary edema, exacerbation of underlying lung disease. The relative risk of developing complications, if unable to climb at least 1 flight of stairs, was calculated to be 1.8 (95% CI 0.7 - 4.6). Conclusion: Stair climbing can be a useful pre-operative tool to predict the risk of postoperative cardiopulmonary complications. (author)

    Mountain-rescue operations require rapid response whilst also ensuring the security of the rescue teams. Rescuing people in a big rock-face is even more difficult if night or fog prevent sight. The paper presents a technical solution to optimally support, under these aggravated conditions, the location of the casualties and the navigation of the rescue team(s) in a rock-face from a coordination station. In doing so, standard components like a smartphones with GPS functionality, a data communication on a client-server basis and VR visualisation software have been adapted to the specific requirements. Remote support of the navigation in steep rocky terrain requires a highly accurate wall model which permits the local experts of the coordination station to dependably estimate geometry and structure of the rock along the rescue route and to convey necessary directives to the retrieval team. Based on terrestrial laser-scans from different locations, such a model has been generated for the mighty Dachstein South Face (Austria) and texturised with digital photographs. Over a twelve-month period, a transdisciplinary team of the Dresden University of Technology (Informatics, Electrical Engineering, Cartography) developed and integrated the various technical modules of the mountain-rescue support-system (digital rock-face model, optimised GPS data transmission between mobile device, server and client, data filtering, and dynamic visualisation component). In summer 2011 the proper functioning of the prototype was demonstrated in a rescue exercise under foggy dusk conditions.

    Full Text Available Abstract Background D-CPR (Defibrillator Cardiopulmonary Resuscitation is a technique for optimal basic life support during cardiopulmonary resuscitation (CPR. Guidelines recommend that healthcare professionals can perform CPR with competence. How CPR training and provision is organized varies between hospitals, and it is our impression that in Sweden this has generally improved during the last 15-20 years. However, some hospitals still do not have any AED (Automated External Defibrillators. The aim was to investigate potential differences in practical skills between different healthcare professions before and after training in D-CPR. Methods Seventy-four healthcare professionals were video recorded and evaluated for adherence to a modified Cardiff Score. A Laerdal Resusci Anne manikin in connection to PC Skill reporting System was used to evaluate CPR quality. A simulated CPR situation was accomplished during a 5-10 min scenario of ventricular fibrillation. Paired and unpaired statistical methods were used to examine differences within and between occupations with respect to the intervention. Results There were no differences in skills among the different healthcare professions, except for compressions per minute. In total, the number of compression per minute and depth improved for all groups (P P Conclusion Nearly all healthcare professionals learned to use the AED. There were no differences in CPR skill performances among the different healthcare professionals.

    Cardiac arrest occurs in approximately 1:12,000 parturients. Among nonpregnant patients who have in-hospital cardiac arrest, those whose spontaneous circulation does not return within 15 to 20 minutes have a high risk of death and disability, so life support efforts are generally stopped after this period. However, among parturients, witnessed in-hospital arrest is often reversible and has a better prognosis. We describe a successful clinical outcome after maternal cardiac arrest and 55 minutes of advanced cardiac life support. This case underscores the importance of high-quality cardiopulmonary resuscitation and raises questions about the appropriate duration of resuscitation efforts in otherwise healthy young mothers with a potentially reversible cause of arrest.

    Full Text Available The objective of this work was to evaluate the vegetative rescue of adult Anadenanthera macrocarpa trees through the induction of epicormic shoots from tree severance and stem ringing, as well as the efficiency of cutting technique on the propagation of the species. The experimental design used was random plots, in a 2 X 2 factorial arrangement, constituted by two techniques for the induction of basal shoots (tree severance and stem ringing and cuttings types (herbaceous cuttings and semihardwoods cuttings, in four replicates and plots of 12 cuttings per repetition. The tree severance and stem ringing were efficient in the induction of basal shoots in adult A. macrocarpa trees. However, the tree severance provided higher emission of basal shoots. The herbaceous cuttings presented higher rooting percentages, independent of vegetative rescue technique. In general, we conclude that the vegetative rescue and the vegetative propagation of A. macrocarpa adult trees are technically efficient.

    2016-02-01

    In this work we present RESCU, a powerful MATLAB-based Kohn-Sham density functional theory (KS-DFT) solver. We demonstrate that RESCU can compute the electronic structure properties of systems comprising many thousands of atoms using modest computer resources, e.g. 16 to 256 cores. Its computational efficiency is achieved from exploiting four routes. First, we use numerical atomic orbital (NAO) techniques to efficiently generate a good quality initial subspace which is crucially required by Chebyshev filtering methods. Second, we exploit the fact that only a subspace spanning the occupied Kohn-Sham states is required, and solving accurately the KS equation using eigensolvers can generally be avoided. Third, by judiciously analyzing and optimizing various parts of the procedure in RESCU, we delay the O (N3) scaling to large N, and our tests show that RESCU scales consistently as O (N2.3) from a few hundred atoms to more than 5000 atoms when using a real space grid discretization. The scaling is better or comparable in a NAO basis up to the 14,000 atoms level. Fourth, we exploit various numerical algorithms and, in particular, we introduce a partial Rayleigh-Ritz algorithm to achieve efficiency gains for systems comprising more than 10,000 electrons. We demonstrate the power of RESCU in solving KS-DFT problems using many examples running on 16, 64 and/or 256 cores: a 5832 Si atoms supercell; a 8788 Al atoms supercell; a 5324 Cu atoms supercell and a small DNA molecule submerged in 1713 water molecules for a total 5399 atoms. The KS-DFT is entirely converged in a few hours in all cases. Our results suggest that the RESCU method has reached a milestone of solving thousands of atoms by KS-DFT on a modest computer cluster.

  10. "Rescue" regimens after Helicobacter pylori treatment failure

    2008-01-01

    Helicobacter pylori (H pylori)infection is the main cause of gastritis,gastroduodenal ulcer disease,and gastric cancer.After more than 20 years of experience in Hpylori treatment,in my opinion,the ideal regimen to treat this infection is still to be found.Currently,apart from having to know first-line eradication regimens well,we must also be prepared to face lyeatment failures.Therefore,in designing a treatment strategy we should not focus on the results of primary therapy alone,but also on the final (overall) eradication rate.The choice of a "rescue" treatment depends on which treatment is used initially.If a clarithromycinbased regimen was used initially,a subsequent metronidazole-based treatment (quadruple therapy)may be used afterwards,and then a levofloxacinbased combination would be a third "rescue" option.Alternatively,it has recently been suggested that levofloxacin-based rescue therapy constitutes an encouraging second-line strategy,representing an alternative to quadruple therapy in patients with previous PPI-clarithromycin-amoxicillin failure,with the advantage of efficacy,simplicity and safety.In this case,a quadruple regimen may be reserved as a third-line rescue option.Finally,rifabutin-based rescue therapy constitutes an encouraging empirical fourthline strategy after multiple previous eradication failures with key antibiotics such as amoxicillin,clarithromycin,metronidazole,tetracycline,and levofloxacin.Even after two consecutive failures,several studies have demonstrated that H pylor/eradication can finally be achieved in almost all patients if several rescue therapies are consecutively given.Therefore,the attitude in H pylori eradication therapy failure,even after two or more unsuccessful attempts,should be to fight and not to surrender.

    Full Text Available Sudden cardiac arrest is one of the leading causes of death in Europe. Bystanders’ early Cardio-Pulmonary Resuscitation (CPR may double or triple survival rates of out-of-hospital cardiac arrest victims. Aim: To investigate nurses’ attitude, in starting or not CPR and also the most frequent reasons that deter them from engaging in. Materials and Methods: The study had a sample of 177 nurses and assistant nurses that were working in nine hospitals of Athens. Nurses filled out the same, predetermined questionnaire, voluntarily and anonymously. The collected answers were analyzed with the help of the statistical program SPSS v.16, using x2 and Kendall’s Tau-B methods. Results: From 177 participants, 78% (137 were women and 22% (40 men with mean age 31 years (±7. According to their education, 16% (28 were Assistant Nurses, 79% (140 Registered Nurses (ATEI, AEI and 5% (9 Nurses had an MSc diploma. Nurses that had been recently trained in certified BLS courses felt more confident and were more willing to start CPR in a known victim (p=0.004 and in an unknown victim (p=0.02 comparing to nurses that had been trained a long time ago or never. Most frequent reasons nurses reported that deter them from starting CPR are the fear of a possible lawsuit (43%, the fear of harming instead of helping (30% and the fear of infectious transmission from victim to rescuer (15%. The fear of harming correlates considerably with lower ages (the younger the nurse the more is afraid, p=0.04 and also correlates substantially with the training in a certified CPR course (the more a nurse is trained, the less is afraid, p<0.001. Accordingly, the fear of infection diminishes as long as the CPR training is repeated (p=0.03. Conclusions: According to the results, there is a necessity of continuous education and re-education of nurses, in certified Basic Life Support programs. With frequent and specialized training, nurses will show more willingness to engage in an out

  12. Lethal systemic Degos disease with prominent cardio-pulmonary involvement

    International Nuclear Information System (INIS)

    Degos disease (DD) is a rare obstructive vasculopathy characterized by distinctive skin lesions. Involvement of the soles, palms and genitalia is rare. In most cases disease has an unfavorable course and involves gastrointestinal tract, central nervous system and occasionally other organs. Pleural and pericardial involvements are usually minor manifestations with prolonged course. Death occurs in approximately 50% of the patients usually due to intestinal perforation or central nervous system bleeding. We describe a 48-year-old man of lethal systemic DD. Widespread skin lesions with involvement of palm plantar surfaces, genitalia and scalp were ignored for 3 years, whereas the disease revealed its own malignant nature. The disorder progressed to nervous, gastrointestinal and cardiopulmonary system that led to death after 5 months from onset of systemic involvement as severe restrictive cardio-pulmonary insufficiency. Autopsy showed diffuse fibrotic changes in serial membranes and internal organs. (author)

    2015-06-01

    Perioperative hyperglycemia, aggravated by cardiopulmonary bypass, is associated with adverse outcome in adult and pediatric patients. Whereas hyperglycemia was originally perceived as an adaptive response to surgical stress, it is now clear that glycemic control is a strategy to reduce adverse outcomes after cardiac surgery and cardiopulmonary bypass. The optimal blood glucose target, whether or not glycemic control should be initiated already intraoperatively, and whether or not perioperative glucose administration affects the impact of glycemic control on ischemia-reperfusion damage remain open questions. Hypoglycemia, the risk of which is increased with glycemic control, is also associated with adverse outcomes. However, it remains controversial whether brief episodes of hypoglycemia, rapidly corrected during glycemic control, have adverse effects on outcome. This review gives an overview of the currently available literature on glycemic control during and after cardiac surgery and focuses on the indicated open questions about this intervention for this specific patient population.

    Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12th, 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate sta-tistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in mul-tivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the oc-currence of post-traumatic stress disorder was the result of the interaction of multiple factors.

    Bystander cardiopulmonary resuscitation (CPR) is a crucial therapy for sudden cardiac arrest. This appreciation produced immense efforts by professional organizations to train laypeople for CPR skills. However, the rate of CPR training is low and varies widely across communities. Several strategies are used in order to improve the rate of CPR training and are performed in some advanced countries. The Chinese CPR training in communities could gain enlightenment from them.

    Objective To study the hormonal and metabolic responses of fetal lamb during cardiopulmonary bypass.Methods Six pregnant ewes underwent fetal cardiopulmonary bypasses with artificial oxygenators and roller pumps for 30 minutes, which maintained the blood gas value at the fetal physiological level. The fetal blood pressure, heart rate, pH value and blood lactate levels were monitored. The levels of catecholamine, cortisol and insulin were measured pre-bypass and then again 30 minutes later. The blood glucose and free fatty acid levels were monitored continuously during the bypass. Fetal hepatic PAS staining was also carried out.Results There were no changes before and during the bypass in fetal blood pressure, heart rate and blood gas. However, pH values decreased and blood lactate levels increased (P<0.05). The fetal catecholamine and cortisol levels increased significantly (P<0.01), while the levels of insulin did not change. The blood glucose and free fatty acid levels increased at the beginning of the bypass (P<0.01), and then gradually slowed down during the bypass. The fetal hepatic PAS staining showed that hepatic glycogen was consumed in large amounts. After 30 minutes of bypass, the fetal lamb would not survive more than 1 hour.Conclusion The fetal lamb has a strong negative reaction to cardiopulmonary bypass.

  6. Cardiopulmonary resuscitation and contrast media reactions in a radiology department

    International Nuclear Information System (INIS)

    AIM: To assess current knowledge and training in the management of contrast media reactions and cardiopulmonary resuscitation within a radiology department. MATERIALS AND METHODS: The standard of knowledge about the management of contrast media reactions and cardiopulmonary resuscitation among radiologists, radiographers and nurses were audited using a two-section questionnaire. Our results were compared against nationally accepted standards. Repeat audits were undertaken over a 28-month period. Three full audit cycles were completed. RESULTS: The initial audit confirmed that although a voluntary training programme was in place, knowledge of cardiopulmonary resuscitation techniques were below acceptable levels (set at 70%) for all staff members. The mean score for radiologists was 50%. Immediate changes instituted included retraining courses, the distribution of standard guidelines and the composition and distribution of two separate information handouts. Initial improvements were complemented by new wallcharts, which were distributed throughout the department, a series of lectures on management of contrast reactions and regular reviews with feedback to staff. In the third and final audit all staff groups had surpassed the required standard. CONCLUSION: Knowledge of contrast media reactions and resuscitation needs constant updating. Revision of skills requires a prescriptive programme; visual display of advice is a constant reminder. It is our contention all radiology departmental staff should consider it a personal duty to maintain their resuscitation skills at appropriate standards. O'Neill, J.M., McBride, K.D.(2001).

  13. Minimizing extinction risk through genetic rescue

    Directory of Open Access Journals (Sweden)

    Waite, T. A.

    2005-12-01

    Full Text Available According to the genetic rescue hypothesis, immigrants can improve population persistence through their genetic contribution alone. We investigate the potential for such rescue using small, inbred laboratory populations of the bean beetle (Callosobruchus maculatus. We ask how many migrants per generation (MPG are needed to minimize the genetic component of extinction risk. During Phase 1, population size was made to fluctuate between 6 and 60 (for 10 generations. During this phase, we manipulated the number of MPG, replacing 0, 1, 3, or 5 females every generation with immigrant females. During Phase 2, we simply set an upper limit on population size (.10. Compared with the 0-MPG treatment, the other treatments were equivalently effective at improving reproductive success and reducing extinction risk. A single MPG was sufficient for genetic rescue, apparently because effective migration rate was inflated dramatically during generations when population size was small. An analysis of quasi-extinction suggests that replicate populations in the 1-MPG treatment benefited from initial purging of inbreeding depression. Populations in this treatment performed so well apparently because they received the dual benefit of purging followed by genetic infusion. Our results suggest the need for further evaluation of alternative schemes for genetic rescue.

    2015-08-01

    Cardiac arrest can occur in any health care setting at any time, requiring nursing staff to be prepared to quickly and adequately perform basic cardiopulmonary resuscitation (CPR). Currently, the American Heart Association certifies health care providers in Basic Life Support (BLS) for a 2-year period, but evidence indicates that psychomotor skills decline well before the end of the certification time frame. Nurses in the ambulatory surgery setting expressed concern regarding their ability to implement CPR successfully, given the infrequent occurrence of cardiac and respiratory arrests. Using a study by Niles et al. as a model, the authors piloted the implementation of brief CPR refresher training at the bedside of an ambulatory surgery center to assess and increase nurse confidence in BLS skills.

    Point-of-care ultrasound examination has been increasingly widely used in pre-hospital care. The use of ultrasound in rescue medicine allows for a quick differential diagnosis, identification of the most important medical emergencies and immediate introduction of targeted treatment. Performing and interpreting a pre-hospital ultrasound examination can improve the accuracy of diagnosis and thus reduce mortality. The authors' own experiences are presented in this paper, which consist in using a portable, hand-held ultrasound apparatus during rescue operations on board a Polish Medical Air Rescue helicopter. The possibility of using an ultrasound apparatus during helicopter rescue service allows for a full professional evaluation of the patient's health condition and enables the patient to be brought to a center with the most appropriate facilities for their condition.

    Mountain sporting activities are an increasingly popular practice that exposes mountaineers to a high risk of adverse events. This report describes a unique case of recovery in an austere environment that involved explosives. In June 2012, a 52-year-old man ascended a cliff tower in the Eastern Alps, Italy. A landslide occurred, and a boulder crushed the climber against a large stone located farther down the cliff, causing compression of the lower limbs and the pelvis with consequent severe musculoskeletal trauma. The National Alpine and Cave Rescue Unit (NACRU) arrived and proceeded with stabilization of the injured climber, which took 6 hours and involved a difficult extrication supported by the Cave Rescue division of NACRU. Unfortunately, during transport to the trauma center of Borgo Trento, Verona, the patient exhibited signs of progressive traumatic shock because of crush syndrome, hypovolemia, and acidosis, which led to cardiac arrest and death. Based on an extensive literature review, this report was determined to be the only one of a mountain rescue using explosives for the extrication of a victim in the Northeast Italian Alps. This case describes how a rescue in austere environments can represent a high-risk situation, and it shows how improvisation and cooperation between rescue teams are crucial for a successful recovery.

    2008-01-01

    The Space Shuttle Hubble repair mission (STS-125) is unique in that a rescue mission (STS-400) has to be ready to launch before STS-125 life support runs out should the vehicle become stranded. The shuttle uses electrical power derived from fuel cells that use cryogenic oxygen and hydrogen (CRYO) to run all subsystems including the Environmental Control System. If the STS-125 crew cannot return to Earth due to failure of a critical subsystem, they must power down all nonessential systems and wait to be rescued by STS-400. This power down will cause the cabin temperature to be 60 F or less and freeze the rest of the vehicle, preventing it from attempting a reentry. After an emergency has been declared, STS-125 must wait at least 7 days to power down since that is the earliest that STS-400 can be launched. Problem The delayed power down of STS-125 causes CYRO to be consumed at high rates and limits the survival time after STS-400 launches to 10 days or less. CRYO will run out sooner every day that the STS-400 launch is delayed (weather at launch, technical issues etc.). To preserve CRYO and lithium hydroxide (LiOH - carbon dioxide removal) the crew will perform no exercise to reduce their metabolic rates, yet each deconditioned STS-125 crewmember must perform an EVA to rescue himself. The cabin may be cold for 10 days, which may cause shivering, increasing the metabolic rate of the STS-125 crew. Solution To preserve LiOH, the STS-125 manifest includes nutrition bars with low carbohydrate content to maintain crew respiratory quotient (RQ) below 0.85 as opposed to the usual shuttle galley food which is rich in carbohydrates and keeps the RQ at approximately 0.95. To keep the crew more comfortable in the cold vehicle warm clothing also has been included. However, with no exercise and limited diet, the deconditioned STS-125 crew returning on STS-400 may not be able to egress the vehicle autonomously requiring a supplemented crash-and-rescue capability.

    Full Text Available An 11-year-old child, a known case of sickle cell anaemia with a history suggestive of sickling crisis in the past was scheduled for surgical pulmonary valvotomy. Pre-operative blood transfusion and hydroxyurea were administered. Pre-operative blood transfusion is indicated in sickle cell disease patients to raise the haematocrit level and lower sickle haemoglobin (HbS levels. Before the start of cardiopulmonary bypass (CPB, exchange transfusion was performed to reduce HbS level and raise adult haemoglobin level. Hypothermia was prevented by employing normothermic CPB.

  8. Digital subtraction cardiopulmonary angiography using FCR (Fuji computed radiography)

    International Nuclear Information System (INIS)

    Digital subtraction cardiopulmonary angiography using FCR was performed on 46 patients including lung cancer, mediastinal tumor, giant bullous formation and others. The images of digital subtraction for pulmonary artery, pulmonary vein and thoracic aorta were studied by comparing to the conventional pulmonary angiogram. Good images of pulmonary artery due to digital subtraction were obtained in 80 % of the 45 cases. This method needed only half volume of contrast media compared to the conventional for obtaining good images and thus reduced side effect. Therefore this method seems to be an usefull pre-operative examination in various chest diseases, especially in case of lung cancer. (author)

    Full Text Available Abstract A treatment strategy of a difficult and unusual problem is presented. We are reporting a case of a patient who had a documented allergy to heparin and required Cardiac surgery for an ASD closure. The anticoagulation regime used during cardiopulmonary bypass was lepirudin based. This report indicates that r-hirudin provides effective anticoagulation, however unless ECT is monitoring, post operative hemorrhage is encountered. Therefore this case is unique not only because of its rarity but also by the fact that it presents the caveats encountered when ECT is not available.

    We studied the stimulus-response characteristics of cardiopulmonary baroreflex control of forearm vascular resistance (FVR) in four groups of male volunteer subjects: i) unfit, ii) physically fit, iii) before and after 10 wk of endurance training (chronic blood volume expansion), and iv) before and after acute blood volume expansion. We assessed the relationship between reflex stimulus, i.e., changes in central venous pressure and response, i.e., FVR, during unloading of cardiopulmonary mechanoreceptors with lower body negative pressure (LBNP, 0 to -20 mm Hg). The slope of the linear relationship between FVR and CVP, the index of the responsiveness of this baroreflex, was significantly diminished (> 50%) in the fit subjects compared with the unfit. The slope of the FVR-CVP relationship was inversely correlated with the subject's total blood volume, suggesting that blood volume expansion was related to the attenuated CP baroreflex. In the exercise training study, maximal oxygen consumption and blood volume increased following 10 wk of endurance training (N = 14) but were unchanged in the time control group (N = 7). The slope of the FVR-CVP relationship was significantly reduced (32%) following 10 wk of training but was unchanged in the time control group. The reduction in slope of the FVR-CVP relationship was inversely related to the increase in blood volume associated with exercise training. Acute blood volume expansion 8 ml.kg-1 body weight with 5% human serum albumin solution) significantly reduced the slope of the FVR-CVP relationship. These data support the hypothesis that the attenuated forearm vascular reflex in physically fit individuals is related to a training-induced hypervolemia.(ABSTRACT TRUNCATED AT 250 WORDS).

    Full Text Available Because of its special hydrology and physiographic environmental conditions, Taiwan experiences a wide range of natural disasters, such as typhoons, floods, slope collapses, debris flows, and earthquakes, resulting in the loss of many lives and properties. Integration of disaster-related information, such as data and models, and the analysis and application of the information are crucial to reduce the damage caused by natural disasters. Therefore, the National Science and Technology Center for Disaster Reduction introduced the information service platform technology of the Research Development and Evaluation Commission to integrate the information of related ministerial departments for added value and use. Related technologies have integrated information of disaster prevention and rescues, assisted the government in disaster prevention and rescue, and effectively reduced the time required for information integration. Additionally, the added value of information applications enabled situational analysis and process handling during natural disasters. This study uses responses to typhoons as examples, and describes how the service application platform of disaster prevention and rescue is used to integrate various data in the response processes and employs related systems to provide users real-time information as a reference for subsequent decision-making.

    Objective To evaluate surgical methods and results of extracardiac conduit total cavopulmonary anastomosis (ECTCPA) without cardiopulmonary bypass (CPB).Methods From May 2000 to April 2003, 11 patients with functional univentricle underwent off-pump EC-TCPA (noCPB group). Their postoperative outcome was retrospectively compared with a 17-patient group who underwent EC-TCPA with cardiopulmonary bypass (CPB group) over a concurrent time period.Results There was 1 operative death in no-CPB group and 2 in CPB group; early postoperative hemodynamics appeared to significantly improve in no-CPB group. Blood and platelet transfusions decreased and blood plasma transfusion significantly lowered in no-CPB group compared with CPB group (P = 0.036). Postoperative courses of patients in no-CPB group were smooth and event free, and extubation time was substantially short. Intensive cares unit stay (P=0.04) and hospital stay (P= 0.02) postoperation were significantly shorter, hospital costs were significantly reduced (P= 0.004) in no-CPB group compared with CPB group.Conclusions EC-TCPA without use of CPB is not a difficult procedure; the procedure results in improvement in postoperative hemodynamics, and decreased use of blood and blood products. It is a more efficient operation with more short recovery time and reduced hospital stay.

    Full Text Available Abstract Background Hemodynamic function may be depressed in the early postoperative stages after cardiac surgery. The aim of this study was the analysis of the myocardial contractility in neonates after cardiopulmonary bypass (CPB and mild hypothermia. Methods Three indices of left ventricular myocardial contractile function (dP/dt, (dP/dt/P, and wall thickening were studied up to 6 hours after CPB in neonatal piglets (CPB group; n = 4. The contractility data were analysed and then compared to the data of newborn piglets who also underwent median thoracotomy and instrumentation for the same time intervals but without CPB (non-CPB group; n = 3. Results Left ventricular dP/dtmax and (dP/dtmax/P remained stable in CPB group, while dP/dtmax decreased in non-CPB group 5 hours postoperatively (1761 ± 205 mmHg/s at baseline vs. 1170 ± 205 mmHg/s after 5 h; p max and (dP/dtmax/P there were no statistically significant differences between the two groups. Comparably, although myocardial thickening decreased in the non-CPB group the differences between the two groups were not statistically significant. Conclusions The myocardial contractile function in survived neonatal piglets remained stable 6 hours after cardiopulmonary bypass and mild hypothermia probably due to regional hypercontractility.

    Full Text Available Introduction: Cardiopulmonary bypass is associated with higher risk of mortality and morbidity, thus it should be investigated regarding the major risk factors. Temperature management have a significant role in postoperative cerebral and neurological complications; however the optimum temperature during cardiopulmonary surgery is not certainly detected. This systematic review has investigated the differences between hypothermia and normothermia regarding postoperative mortality. Method: PubMed was searched for the relevant articles. Only English language articles were included with no time limitation. Data regarding in-hospital patient deaths provided in each article mostly within 30 days after the surgery, were extracted and compared based on relative risk reduction (RRR, absolute risk reduction (ARR, and number needed to treat (NNT.Result: Totally, 28 articles were retrieved and extracted. The mortality rate was zero in hypothermic and normotehrmic groups of 8/28 included studies, thus the RRR, ARR, and NNT could not be calculated. There were no significant differences between investigated groups of each included studies regarding the patients’ age, gender, and preoperative conditions.Conclusions: No significant difference was obtained between two studied groups. Similar prevalence of death observed between hypothermic and normothermic groups might be due to the sample size of studies, or the subsequent cares performed in intensive care units that assist to reduce the postoperative mortality rate. According to the obtained results, both of these procedures might be similarly safe regarding mortality rate.

    We studied alterations of chest geometry during conventional cardiopulmonary resuscitation in anesthetized immature swine. Pulsatile force was applied to the sternum in increments to determine the effects of increasing compression on chest geometry and intrathoracic vascular pressures. In 2-wk- and 1-mo-old piglets, permanent changes in chest shape developed due to incomplete recoil of the chest along the anteroposterior axis, and large intrathoracic vascular pressures were generated. In 3-mo-old animals, permanent chest deformity did not develop, and large intrathoracic vascular pressures were not produced. We propose a theoretical model of the chest as an elliptic cylinder. Pulsatile displacement along the minor axis of an ellipse produces a greater decrease in cross-sectional area than displacement of a circular cross section. As thoracic cross section became less circular due to deformity, greater changes in thoracic volume, and hence pressure, were produced. With extreme deformity at high force, pulsatile displacement became limited, diminishing pressure generation. We conclude that changes in chest geometry are important in producing intrathoracic intravascular pressure during conventional cardiopulmonary resuscitation in piglets. PMID:3610916

    Advanced cardiovascular life support guidelines exist, yet there are variations in clinical practice. Our study aims to describe the utilization of medications during resuscitation from in-hospital cardiopulmonary arrest. A retrospective review of patients who suffered a cardiopulmonary arrest from May 2008 to June 2014 was performed. Clinical and resuscitation data, including timing and dose of medications used, were extracted from the electronic medical record and comparisons made. A total of 94 patients were included in the study. Patients were divided into different groups based on the medication combination used during resuscitation: (1) epinephrine; (2) epinephrine and bicarbonate; (3) epinephrine, bicarbonate, and calcium; (4) epinephrine, bicarbonate, and epinephrine drip; and (5) epinephrine, bicarbonate, calcium, and epinephrine drip. No difference in baseline demographics or clinical data was present, apart from history of dementia and the use of calcium channel blockers. The number of medications given was correlated with resuscitation duration (Spearman's rank correlation = 0.50, p <0.001). The proportion of patients who died during the arrest was 12.5% in those who received epinephrine alone, 30.0% in those who received only epinephrine and bicarbonate, and 46.7% to 57.9% in the remaining groups. Patients receiving only epinephrine had shorter resuscitation durations compared to that of the other groups (p <0.001) and improved survival (p = 0.003). In conclusion, providers frequently use nonguideline medications in resuscitation efforts for in-hospital cardiopulmonary arrests. Increased duration and mortality rates were found in those resuscitations compared with epinephrine alone, likely due to the longer resuscitation duration in the former groups. PMID:27015887

    We investigated the relation between left ventricular dysfunction and myocardial edema in dogs with heartworm (Dirofilaria immitis) infection that were undergoing cardiopulmonary bypass. Dogs with and without D immitis were anesthetized by continuous thiopental infusion and were mechanically ventilated. Sonomicrometry crystals were placed on the long and short axes of the left ventricle, and a Millar pressure transducer was placed in the left ventricular chamber. Pressure-volume loops were digitized and continuously recorded. Dogs with and without D immitis were placed on standard hypothermic cardiopulmonary bypass, with 1 hour of aortic cross-clamp. Wet-to-dry weight ratio corrected for residual blood volume was used to quantitate the volume of myocardial edema. Preload recruitable stroke work was used as a preload-independent index of systolic function. Tau, the isovolumic relaxation time constant, was determined to assess diastolic relaxation. Dogs with D immitis had increased baseline myocardial wet-to-dry weight ratio. After cardiopulmonary bypass, myocardial edema increased in all dogs. Acute edema attributable to cardiopulmonary bypass decreased preload recruitable stroke work in all dogs of both groups, and dogs with D immitis could not be weaned from cardiopulmonary bypass. Myocardial edema increased diastolic relaxation times (tau) in dogs with and without D immitis. We conclude that cardiopulmonary bypass and heartworm infection induce myocardial edema. This edema compromises left ventricular systolic and diastolic function making D immitis an important confounding factor in weaning dogs from cardiopulmonary bypass. PMID:7717590

    We report the case of a 17-month-old child who underwent laparotomy under general anesthesia and caudal block. Electrocardiogram ST-T changes were observed after local anesthetic injection. The prompt use of Intralipid 30% was successful in normalizing ECG alterations. Our experience is consistent with previous literature, mainly carried out in adults. Thereby, we conduct a brief review of the subject in pediatrics. As a major conclusion, we strongly recommend the "fast-track" lipid rescue as soon as this severe complication is detected.

    While technology of our satellite systems have greatly improved the quality of observations over the past 50 years, it is the legacy of the first global coverage environment satellites, the Nimbus systems launched by NASA in the mid-1960s, that marks the beginning of a unique perspective from space. Such early data can extend our climate record and provide important context in longer-term climate changes. Unfortunately, the Nimbus data nearly disappeared before its value was recognized and attempts to recover the data were undertaken. While the Nimbus data was never truly lost, it was in a form that could not be read and was not organized in a way that could be accessed with modern computer systems. The rescue and recovery of the Nimbus data began in 2007 with an initiative by the NASA Goddard Space Flight Center. Without the Goddard efforts, the early Nimbus data might be forever dark. The Nimbus Rescue Project has just completed processing and archival of the Nimbus 4 visible and infrared observations from 1970 and 1971. This adds to our rescue efforts from Nimbus 1, 2 and 3 for 1964, 1966 and 1969. The procedures to recover the Nimbus data, from both film and tape, could be used by other data rescue projects, however the algorithms presented will tend to be Nimbus specific. The compositing of the mapped minimum brightness over weekly intervals resulted in never before seen views of the Polar Regions, such as a visible light view of the Antarctic ice extent from October 1970 (Figure 1). The Nimbus data recovery and reprocessing into modern formats was important, however it was the utility of the data as a part of the satellite climate record that made it valuable. Data rescue projects are often both difficult and time consuming but the data they bring back to the science community makes these efforts worthwhile.

    Three years ago, when a cave-in at the San José mine in Chile trapped 33 men under 700,000 metric tons of rock, experts estimated the probability of getting them out alive at less than 1%. Yet, after spending a record 69 days underground, all 33 were hoisted up to safety. The inspiring story of their rescue is a case study in how to lead in situations where the stakes, risk, and uncertainty are incredibly high and time pressure is intense. Today executives often find themselves in similar straits. When they do, many feel torn. Should they be directive, taking charge and commanding action? Or should they be empowering, enabling innovation and experimentation? As the successful example of André Sougarret, the chief of the mine rescue operation, shows, the answer is yes--to both. The choice is a false dichotomy. Implementing this dual approach involves three key tasks. Each has directive and enabling components. The first task is envisioning, which requires instilling both realism and hope. The second task is enrolling, which means setting clear boundaries for who is on and off the team, but inviting in helpful collaborators. The third task is engaging--leading disciplined execution while encouraging innovation and experimentation. The authors of this article describe how Sougarret ably juggled all of these tasks, orchestrating the efforts of hundreds of people from different organizations, areas of expertise, and countries in an extraordinary mission that overcame impossible odds.

    Myhre syndrome, a connective tissue disorder characterized by deafness, restricted joint movement, compact body habitus, and distinctive craniofacial and skeletal features, is caused by heterozygous mutations in SMAD4. Cardiac manifestations reported to date have included patent ductus arteriosus, septal defects, aortic coarctation and pericarditis. We present five previously unreported patients with Myhre syndrome. Despite varied clinical phenotypes all had significant cardiac and/or pulmonary pathology and abnormal wound healing. Included herein is the first report of cardiac transplantation in patients with Myhre syndrome. A progressive and markedly abnormal fibroproliferative response to surgical intervention is a newly delineated complication that occurred in all patients and contributes to our understanding of the natural history of this disorder. We recommend routine cardiopulmonary surveillance for patients with Myhre syndrome. Surgical intervention should be approached with extreme caution and with as little invasion as possible as the propensity to develop fibrosis/scar tissue is dramatic and can cause significant morbidity and mortality.

  12. Cardiopulmonary resuscitation in the elderly: a clinical and ethical perspective

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The daily practice of cardiopulmonary resuscitation (CPR) in elderly patients has brought up the attention of outcome research and resource allocation. Determinants to predict survival have been well identified. There has been empirical evidence that CPR is of doubtful utility in the geriatric population, more studies have showed controversial data. Sometimes situations in which CPR needs to be given in the elderly, causes stress to healthcare providers, due to lack of communication of the patient's wishes and the belief that it will not be successful. It is of importance to state that we have the duty to identify on time the patients that will most likely benefit from CPR, and find out the preferences of the same. Whenever it is possible to institute these guidelines, we will avoid patient suffering.

  13. Coronary blood flow during cardiopulmonary resuscitation in swine

    International Nuclear Information System (INIS)

    Recent papers have raised doubt as to the magnitude of coronary blood flow during closed-chest cardiopulmonary resuscitation. We will describe experiments that concern the methods of coronary flow measurement during cardiopulmonary resuscitation. Nine anesthetized swine were instrumented to allow simultaneous measurements of coronary blood flow by both electromagnetic cuff flow probes and by the radiomicrosphere technique. Cardiac arrest was caused by electrical fibrillation and closed-chest massage was performed by a Thumper (Dixie Medical Inc., Houston). The chest was compressed transversely at a rate of 66 strokes/min. Compression occupied one-half of the massage cycle. Three different Thumper piston strokes were studied: 1.5, 2, and 2.5 inches. Mean aortic pressure and total systemic blood flow measured by the radiomicrosphere technique increased as Thumper piston stroke was lengthened (mean +/- SD): 1.5 inch stroke, 23 +/- 4 mm Hg, 525 +/- 195 ml/min; 2 inch stroke, 33 +/- 5 mm Hg, 692 +/- 202 ml/min; 2.5 inch stroke, 40 +/- 6 mm Hg, 817 +/- 321 ml/min. Both methods of coronary flow measurement (electromagnetic [EMF] and radiomicrosphere [RMS]) gave similar results in technically successful preparations (data expressed as percent prearrest flow mean +/- 1 SD): 1.5 inch stroke, EMF 12 +/- 5%, RMS 16 +/- 5%; 2 inch stroke, EMF 30 +/- 6%, RMS 26 +/- 11%; 2.5 inch stroke, EMF 50 +/- 12%, RMS 40 +/- 20%. The phasic coronary flow signal during closed-chest compression indicated that all perfusion occurred during the relaxation phase of the massage cycle. We concluded that coronary blood flow is demonstrable during closed-chest massage, but that the magnitude is unlikely to be more than a fraction of normal

    Full Text Available Technology has become the solution to many long-standing problems, and while current technologies may be effective, it is far from fully addressing the hug, complex, difficult and challenging tasks associated with disaster missions and risky intervention. The challenge is in finding creative, reliable and applicable technical solutions in such highly constrained and uncertain environment. In addition, it is necessary to overcome constrains on resources by developing innovative, cost effective and practical technology. Robotics can play important intelligent and technological roles that support first response equipment in harsh and dangerous environments while replacing rescue personnel from entering unreachable or unsafe places. Robotics solutions that are well adapted to local conditions of unstructured and unknown environment can greatly improve safety and security of personnel as well as work efficiency, productivity and flexibility. Solving and fulfilling the needs of such tasks presents challenges in robotic mechanical structure and mobility, sensors and sensor fusion, autonomous and semi autonomous control, planning and navigation, and machine intelligence. This paper categorizes the source of disasters and associated missions, and highlights the needs for suitable and reliable technology and technical and functional requirements of robotic systems to fulfill task objectives. In addition, it shows that robotic technologies can be used for disasters prevention or early warning, intervention and recovery efforts during disasters with all possible kinds of relevant missions while ensuring quality of service and safety of human beings. Some of these missions may include: demining, search and rescue, surveillance, reconnaissance and risk assessment, evacuation assistance, intrusion/victim detection and assessment, etc.

    Background Patients with repaired tetralogy of Fallot (TOF) usually experience progressive right ventricle (RV) dysfunction due to pulmonary regurgitation (PR). This could further worsen the cardiopulmonary function. This study aimed to compare the changes in patient exercise cardiopulmonary test and cardiac magnetic resonance imaging, and consider the implication of these changes. Methods Our study examined repaired TOF patients who underwent cardiopulmonary exercise test (CPET) to obtain maximal (peak oxygen consumption, peak VO2) and submaximal parameters (oxygen uptake efficiency plateau, oxygen uptake efficiency plateau (OUEP), and ratio of minute ventilation to carbon dioxide production, VE/VCO2 slope). Additionally, the hemodynamic status was assessed by using cardiac magnetic resonance. Criteria for exclusion included TOF patients with pulmonary atresia, atrioventricular septal defect, or absence of pulmonary valve syndrome. Results We enrolled 158 patients whose mean age at repair was 7.8 ± 9.1 years (range 0.1-49.2 years) and the mean patient age at CPET was 29.5 ± 12.2 years (range 7.0-57.0 years). Severe PR (PR fraction ≥ 40%) in 53 patients, moderate in 55, and mild (PR fraction 163 ml/m2. The mean left ventricular ejection fraction (LVEF) was 63 ± 8%, left ventricular end-diastolic volume index (LVEDVi) was 65 ± 12 ml/m2, and LVESVi was 25 ± 14 ml/m2. CPET revealed significantly decreased peak VO2 (68.5 ± 14.4% of predicted), and fair OUEP (90.3 ± 14.1% of predicted) and VE/VCO2 slope (27.1 ± 5.3). PR fraction and age at repair were negatively correlated with maximal and submaximal exercise indicators (peak VO2 and OUEP). Left ventricular (LV) function and size were positively correlated with peak VO2 and OUEP. Conclusions The results of CPET showed that patients with repaired TOF had a low maximal exercise capacity (peak VO2), but a fair submaximal exercise capacity (OUEP and VE/VCO2 slope), suggesting limited exercise capability in high

  18. Utilising cardiopulmonary bypass for cancer surgery. Malignancy-induced protein C deficiency and thrombophilia.

    LENUS (Irish Health Repository)

    Marshall, C

    2012-02-03

    Cardiopulmonary bypass has evolved over the last 30 years. It is an important tool for the cardiac surgeon today and also has applications in non-cardiac operations such as surgery to extract tumours. Such patients undergoing surgery for cancer may be at an increased risk of a thromboembolic event post surgery, due to disturbances in the normal clotting pathway leading to hypercoagulability. One such disturbance is malignancy-induced Protein C deficiency. A deficiency of Protein C can cause hypercoagulabitity. Recent studies have examined cardiopulmonary bypass and inherited Protein C deficiency. However, surgery for cancer patients with a malignancy-induced Protein C deficiency involving cardiopulmonary bypass has not been reported. Surgery using CPB in these patients may result in increased morbidity and mortality. The objective of this article is to review the literature in order to discuss the occurrence, the aetiology and possible management of cancer patients with malignancy-induced Protein C deficiencies that require cardiopulmonary bypass for their surgery.

    Full Text Available Cardiopulmonary exercise testing is a method used to assess the exercise capacity. It is used in cardiology to define the diagnostic and prognostic information, the treatment and its effectiveness. This method is also useful in sport medicine and in occupational medicine. The cardiopulmonary exercise test involves measuring of gas exchange during exercise testing. The article presents the main parameters assessed during the test and the indications and contraindications for conducting the test. It also reveals the results of recently published clinical trials on the use of cardiopulmonary exercise test in patients with cardiovascular disease and in the working population. The study included variability of respiratory parameters during the cardiopulmonary exercise test and after its completion, as well as their impact on the prognostic value. In addition, the results of a study involving an optimal choice of interval training on the basis of oxygen consumption at peak exercise are summarized. Med Pr 2014;65(5:665–674

    Stranded marine mammals have long attracted public attention. Those that wash up dead are, for all their value to science, seldom seen by the public as more than curiosities. Animals that are sick, injured, orphaned or abandoned ignite a different response. Generally, public sentiment supports any effort to rescue, treat and return them to sea.

    Introduction Cardiopulmonary bypass causes a series of inflammatory events that have adverse effects on the outcome. The release of cytokines, including interleukins, plays a key role in the pathophysiology of the process. Simultaneously, cessation of ventilation and pulmonary blood flow contribute to ischaemia–reperfusion injury in the lungs when reperfusion is maintained. Collapse of the lungs during cardiopulmonary bypass leads to postoperative atelectasis, which correlates with the amount...

    IEDA (Integrated Earth Data Applications, www.iedadata.org), the NSF facility that operates EarthChem, the Marine Geoscience Data System, and the System for Earth Sample Registration, launched a Data Rescue Initiative in 2013 to advance preservation and re-use of valuable legacy datasets that are in danger of being lost. As part of this initiative, IEDA established a competition for Data Rescue Mini-Awards that provide modest funds to investigators to properly compile, document, and transfer legacy data sets to IEDA. Applications from late-career and near-retirement investigators were specifically encouraged. Awardees were given approximately six months to complete their data rescue activities. Three projects were awarded in 2013: (1) Geochemistry of Lunar Glasses: assembly of major element, trace element, volatile element, and isotope ratio data for lunar volcanic glasses and lunar impact glasses, (2) Geochemical and Geochronological data from Fiji, Izu-Bonin-Marianas, and Endeavor segment: assembly of published and unpublished data and metadata from large rock sample collections, and (3) Near-bottom Magnetic Data: curation and archival of 35 years of high-resolution, near-bottom magnetic field data from deeptowed platforms, submersibles, and ROVs. IEDA is working closely with the awardees to guide and support the data rescue effort and to assist with specific challenges related to outdated storage media or technology, diversity of platforms over decades of research, and the lack of established standards for data documentation. In this contribution we describe procedures and tools used for each project, summarize lessons learned and best practices, and present the final output of each data rescue project. Depending on the experiences of this first year and the availability of funds, we plan to continue the competition in future years.

    An extracorporeal centrifugal blood pump with a hydrodynamically levitated impeller was developed for use in a durable extracorporeal membrane oxygenation (ECMO) system. The present study examined the biocompatibility of the blood pump during long-term use by conducting a series of 30-day chronic animal experiments. The ECMO system was used to produce a percutaneous venoarterial bypass between the venae cavae and carotid artery in adult goats. No anticoagulation or antiplatelet therapy was administered during the experiments. Three out of four animals survived for the scheduled 30-day period, and the blood pumps and membrane oxygenators both exhibited sufficient hydrodynamic performance and good antithrombogenicity, while one animal died of massive bleeding from the outflow cannulation site. The animals' plasma free hemoglobin had returned to within the normal range by 1 week after the surgical intervention, and their hemodynamic and biochemistry parameters remained within their normal ranges throughout the experiment. The explanted centrifugal blood pumps did not display any trace of thrombus formation. Based on the biocompatibility demonstrated in this study, the examined centrifugal blood pump, which includes a hydrodynamically levitated impeller, is suitable for use in durable ECMO systems.

    Thalidomide, a sedative drug given to pregnant women, unfortunately caused limb deformities in thousands of babies. Recently the drug was revived because of its therapeutic potential; however the search is still ongoing for an antidote against thalidomide induced limb deformities. In the current study we found that nitric oxide (NO) rescues thalidomide affected chick (Gallus gallus) and zebrafish (Danio rerio) embryos. This study confirms that NO reduced the number of thalidomide mediated limb deformities by 94% and 80% in chick and zebrafish embryos respectively. NO prevents limb deformities by promoting angiogenesis, reducing oxidative stress and inactivating caspase-3 dependent apoptosis. We conclude that NO secures angiogenesis in the thalidomide treated embryos to protect them from deformities. PMID:22997553

    Two approaches to a satellite system for air and sea rescue to be put into use by the 1990s, one employing polar-orbiting satellites and the other using fixed geosynchronous satellites over the equator, are discussed. A battery-powered transmitter on a ship or aircraft would be activated in an accident to emit a low-power omnidirectional signal that would be relayed by a satellite to an earth station. The polar-orbiting approach, now being evaluated on a small-scale with the Cospas-Sarsat system, allows complete coverage of the earth, including the poles, and provides a fix on the origin of the distress signals by means of the Doppler shift. A parallel effort for the testing of geostationary satellites to measure system sensitivity to various interference sources, to optimize design, and to measure land and sea performance is reviewed.

    Full Text Available Due to various factors, the global scope disaster events occur inevitably every year. Terrorism, natural disasters or destructive earthquakes tend to cause a large number of people buried in the ruins of buildings. The research of search and rescue instruments research is mainly focused on snake-like robot and life detector both at home and abroad. The endoscopic search and rescue robot in this paper combines the characteristics of these two kinds of search and rescue equipment. This thesis mainly studies the insertion mechanism of endoscopic flexible search and rescue robot. Based on the mechanics characteristics of the flexible robot body, this paper analyzes several common failure modes during the insertion into the ruins. This article puts forward the scheme of segmented gradual pulling-pushing, which plays an important role in promoting search and rescue work.

  14. Posture manipulation for rescue activity via small traction robots

    International Nuclear Information System (INIS)

    We discuss a conceptual design of rescue robots against nuclear-power plant accidents. We claim that the rescue robots in nuclear-power plants should have the following properties. (1) The size is small. (2) The structure is simple. (3) The number of the robots is large. This paper studies the rescue robots to rescue people in an area polluted with radioactive leakage in nuclear power institutions. In particular, we propose a rescue system which consists of a group of small mobile robots. First, small traction robots set the posture of the fainted victims to carry easily, and carry them to the safety space with the mobile robots for the stretcher composition. In this paper, we describe the produced small traction robots. And, we confirm that the robots can manipulate a 40 kg dummy doll's posture. We also examine the optimal number of robots from a perspective of working efficiency in the assumption spot. (author)

  15. Rescue of marker phenotypes mediated by somatic cell hybridization

    International Nuclear Information System (INIS)

    The effect of irradiation prior to virus-induced cell fusion on the frequency of hybrid production has been measured as a function of radiation dose. The Chinese hamster line wg3h (HGPRT-) was crossed with the TK- mutants; Chinese hamster A23 or mouse 3T34E, and hybrids were selected in HAT medium. Irradiation of one (marker rescue) or both (mutual rescue) partners before fusion yielded qualitatively different results. After X-irradiation, marker rescue curves were of single-hit type, with D0 values about five-fold greater than the irradiated parent cell. Mutual rescue curves were of the multi-hit type, with zero-dose extrapolation value (n) greater than that of the more resistant partner, but no significant alteration in D0. Qualitatively similar results were obtained after U.V.- irradiation, but the probability of rescue per surviving parent cell was

    In the past several decades, cardiopulmonary exercise testing (CPX) has seen an exponential increase in its evidence base. The growing volume of evidence in support of CPX has precipitated the release of numerous scientific statements by societies and associations. In 2012, the European Association for Cardiovascular Prevention & Rehabilitation and the American Heart Association developed a joint document with the primary intent of redefining CPX analysis and reporting in a way that would streamline test interpretation and increase clinical application. Specifically, the 2012 joint scientific statement on CPX conceptualized an easy-to-use, clinically meaningful analysis based on evidence-vetted variables in color-coded algorithms; single-page algorithms were successfully developed for each proposed test indication. Because of an abundance of new CPX research in recent years and a reassessment of the current algorithms in light of the body of evidence, a focused update to the 2012 scientific statement is now warranted. The purposes of this update are to confirm algorithms included in the initial scientific statement not requiring revision, to propose revisions to algorithms included in the initial scientific statement, to propose new algorithms based on emerging scientific evidence, to further clarify the application of oxygen consumption at ventilatory threshold, to describe CPX variables with an emerging scientific evidence base, to describe the synergistic value of combining CPX with other assessments, to discuss personnel considerations for CPX laboratories, and to provide recommendations for future CPX research.

  18. Computed tomography during cardiopulmonary resuscitation using automated chest compression devices - an initial study

    International Nuclear Information System (INIS)

    The purpose of the study was to evaluate both CT image quality in a phantom study and feasibility in an initial case series using automated chest compression (A-CC) devices for cardiopulmonary resuscitation (CPR). Multidetector CT (MDCT) of a chest/heart phantom (Thorax-CCI, QRM, Germany) was performed with identical protocols of the phantom alone (S), the phantom together with two different A-CC devices (A: AutoPulse, Zoll, Germany; L: LUCAS, Jolife, Sweden), and the phantom with a LUCAS baseplate, but without the compression unit (L-bp). Nine radiologists evaluated image noise quantitatively (n=244 regions, Student's t-test) and also rated image quality subjectively (1-excellent to 6-inadequate, Mann-Whitney U-test). Additionally, three patients during prolonged CPR underwent CT with A-CC devices. Mean image noise of S was increased by 1.21 using L-bp, by 3.62 using A, and by 5.94 using L (p<0.01 each). Image quality was identical using S and L-bp (1.64 each), slightly worse with A (1.83), and significantly worse with L (2.97, p<0.001). In all patient cases the main lesions were identified, which led to clinical key decisions. Image quality was excellent with L-bp and good with A. Under CPR conditions initial cases indicate that MDCT diagnostics supports either focused treatment or the decision to terminate efforts. (orig.)

  19. Clinical Review: Management of weaning from cardiopulmonary bypass after cardiac surgery

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available A sizable number of cardiac surgical patients are difficult to wean off cardiopulmonary bypass (CPB as a result of structural or functional cardiac abnormalities, vasoplegic syndrome, or ventricular dysfunction. In these cases, therapeutic decisions have to be taken quickly for successful separation from CPB. Various crisis management scenarios can be anticipated which emphasizes the importance of basic knowledge in applied cardiovascular physiology, knowledge of pathophysiology of the surgical lesions as well as leadership, and communication between multiple team members in a high-stakes environment. Since the mid-90s, transoesophageal echocardiography has provided an opportunity to assess the completeness of surgery, to identify abnormal circulatory conditions, and to guide specific medical and surgical interventions. However, because of the lack of evidence-based guidelines, there is a large variability regarding the use of cardiovascular drugs and mechanical circulatory support at the time of weaning from the CPB. This review presents key features for risk stratification and risk modulation as well as a standardized physiological approach to achieve successful weaning from CPB.

    Cardiopulmonary resuscitation (CPR) is an effective way to rescue patients with cardiac arrest (CA) whose incidence rate has been increasing with the increase of cardiovascular and cerebrovascular diseases in recent years. After 50 years of exploration and practice of CPR, the survival rate on discharge of CA is far from satisfactory. While more efforts are being made to perfect CPR approach, the experience should be summarized and the misunderstanding should be avoided. We suggest that the main misunderstanding of CPR lies in stereotyped CPR procedure, CPR ventilation, CPR compression, open chest cardiac massage, CPR access, CPR back veneer and time limit are not adaptable to practice. We should work out a better method to guide CPR application in clinical practice.%心脏骤停威胁人们的生命健康,且近年随着心脑血管疾病增加其发病率逐渐攀升,心肺复苏(cardiopulmonaryresuscitation,CPR)作为抢救心脏骤停的有效方法,经过50余年的探索实践,患者的生存出院率仍不理想,故在发掘完善新方法的同时,亦应不断总结经验教训,找出CPR进程中的误区,笔者认为当前临床主要存在CPR程序“刻板化”、CPR通气“死腔化”、CPR按压“形式化”、CPR开胸“概念化”、CPR通路“单一化”、CPR背板“无声化”及CPR时限“教条化”,并结合经验积极尝试修正,以指导临床正确把握并实施CPR.

    Entin, Elliot E.; Kerrigan, Caroline; Serfaty, Daniel; Young, Philip

    1998-01-01

    The goals of this project were to identify and investigate aspects of team and individual decision-making and risk-taking behaviors hypothesized to be most affected by prolonged isolation. A key premise driving our research approach is that effects of stressors that impact individual and team cognitive processes in an isolated, confined, and hazardous environment will be projected onto the performance of a simulation task. To elicit and investigate these team behaviors we developed a search and rescue task concept as a scenario domain that would be relevant for isolated crews. We modified the Distributed Dynamic Decision-making (DDD) simulator, a platform that has been extensively used for empirical research in team processes and taskwork performance, to portray the features of a search and rescue scenario and present the task components incorporated into that scenario. The resulting software is called DD-Search and Rescue (Version 1.0). To support the use of the DDD-Search and Rescue simulator in isolated experiment settings, we wrote a player's manual for teaching team members to operate the simulator and play the scenario. We then developed a research design and experiment plan that would allow quantitative measures of individual and team decision making skills using the DDD-Search and Rescue simulator as the experiment platform. A description of these activities and the associated materials that were produced under this contract are contained in this report.

    JAXA (Japan Aerospace Exploration Agency) has been conducting a research project named SAVERH (Situation Awareness and Visual Enhancer for Rescue Helicopter) with Shimadzu Corporation and NEC from 2008. SAVERH aims at inventing a method of presenting suitable information to the pilot to support search and rescue missions. An integrated system comprising an HMD (Helmet-Mounted Display) and a FLIR (Forward Looking Infrared) sensor were installed in a JAXA research helicopter, and a series of flight tests was conducted to evaluate the benefit of presenting FLIR images on the HMD in night flight. Three pilots evaluated the display system during six night flights, considering terrain and position awareness. The tests showed that use of FLIR gave better route tracking performance, and the effectiveness of head-slaved FLIR on an approach task was shown by subjective pilot rating.

    Management of patients treated with CardioWest Total Artificial Heart (CW-TAH) as a bridge to heart transplantation (HTx) is complicated by difficulties in determining the optimal timing of transplantation. We present a case of a 53-year-old man supported as an outpatient with a CW-TAH, whose condition deteriorated following exchange of the portable driver. The patient was followed-up with serial cardiopulmonary exercise testing (CPET) which demonstrated a fall of peak VO2 to below 12 ml/kg/min following driver substitution, and the patient was subsequently treated with urgent orthotopic HTx. This case highlights the potential utility of CPET as a means for monitoring and indicating timing of HTx in patients with CW-TAH, as well as the potential for clinical deterioration following portable driver substitution.

    A pulsatile pump driven by a coil spring, which was designed and constructed by us, is described in this report. It consists of two main parts, a disposable blood chamber and a driving section. The blood chamber has two leaflet valves and a piston, which is covered with two bellofram rolling diaphragms and moves into the housing to draw in and eject the blood. The driving section consists of three cams, an electric motor and a coil spring. The ejection force is wholly produced by the compressed coil spring and is transmitted to the piston in the blood chamber by a rod. This pump allows the ejection pressure, the beat rates, and the stroke volume all to be changed independently. The performance of the pump was tested by using a circulation model where the beat rate was adjusted from 30 to 250 bpm. The output subsequently increased from 0.8 l/min to 5.7 l/min and the stroke volume, from 20.4 ml to 36.7 ml. This new pump has been used for clinical cardiopulmonary bypasses in 24 patients of open heart surgery and the pressure traces during perfusion resembled those of the patients' own hearts.

To evaluate the role of exercise testing through the 6MWT (6-minute walk test and CPET (cardiopulmonary exercise testing in the survival of patients with IPF. Methods. This is a prospective, observational study evaluating in 25 patients the relationship between exercise variables through both the 6MWT and CPET and survival. Results. By the end of the observational period 17 patients were alive (33% mortality. Observation ranged from 9 to 64 months. VE/VCO2 slope (slope of relation between minute ventilation and CO2 production, VO2 peak/kg (peak oxygen consumption/kg, VE/VCO2 ratio at anaerobic threshold, 6MWT distance, desaturation, and DLCO% were significant predictors of survival while VE/VCO2 slope and VO2 peak/kg had the strongest correlation with outcome. The optimal model for mortality risk estimation was VO2 peak/kg + DLCO% combined. Furthermore, VE/VCO2 slope and VO2 peak/kg were correlated with distance and desaturation during the 6MWT. Conclusion. The integration of oxygen consumption and diffusing capacity proved to be a reliable predictor of survival because both variables reflect major underlying physiologic determinants of exercise limitation.

    Objectives. Studies have shown that healthcare personnel hesitate to perform defibrillation due to individual or organisational attitudes. We aimed to assess trainers' attitudes towards cardiopulmonary resuscitation and defibrillation (CPR-D), Current Care Guidelines, and associated training. Methods. A questionnaire was distributed to CPR trainers attending seminars in Finland (N = 185) focusing on the updated national Current Care Guidelines 2011. The questions were answered using Likert scale (1 = totally disagree, 7 = totally agree). Factor loading of the questionnaire was made using maximum likelihood analysis and varimax rotation. Seven scales were constructed (Hesitation, Nurse's Role, Nontechnical Skill, Usefulness, Restrictions, Personal, and Organisation). Cronbach's alphas were 0.92–0.51. Statistics were Student's t-test, ANOVA, stepwise regression analysis, and Pearson Correlation. Results. The questionnaire was returned by 124/185, 67% CPR trainers, of whom two-thirds felt that their undergraduate training in CPR-D had not been adequate. Satisfaction with undergraduate defibrillation training correlated with the Nontechnical Skills scale (p Nurse's Role (p CPR trainers and some feel uncertain of defibrillation. The train-the-trainers courses and undergraduate medical education should focus more on practical scenarios with defibrillators and nontechnical skills. PMID:27144027

    Why you should be grateful to the Domain Name System at CERN.   Incidents involving so-called “drive-by” infections and “ransomware” are on the rise. Whilst an up-to-date and fully patched operating system is essential; whilst running anti-virus software with current virus signature files is a must; whilst “stop --- think --- don’t click” surely helps, we can still go one step further in better protecting your computers: DNS to the rescue. The DNS, short for Domain Name System, translates the web address you want to visit (like “http://cern.ch”) to a machine-readable format (the IP address, here: “188.184.9.234”). For years, we have automatically monitored the DNS translation requests made by your favourite web browser (actually by your operating system, but that doesn’t matter here), and we have automatically informed you if your computer tried to access a website known to hos...

  13. Modulation of NF-KB in rescued irradiated cells

    International Nuclear Information System (INIS)

    Studies by different groups on the rescue effect, where unirradiated bystander cells mitigated the damages in the irradiated cells, since its discovery by the authors' group in 2011 were first reviewed. The properties of the rescue effect were then examined using a novel experimental set-up to physically separate the rescue signals from the bystander signals. The authors' results showed that the rescue effect was mediated through activation of the nuclear factor-KB (NF-KB) response pathway in the irradiated cells, and that the NF-KB activation inhibitor BAy-11-7082 did not affect the activation of this response pathway in the irradiated cells induced by direct irradiation.

    2016-01-01

    Full Text Available Context: Cardiopulmonary resuscitation (CPR and emergency cardiovascular care guidelines are periodically renewed and published by the American Heart Association. Formal training programs are conducted based on these guidelines. Despite widespread training CPR is often poorly performed. Hospital educators spend a significant amount of time and money in training health professionals and maintaining basic life support (BLS and advanced cardiac life support (ACLS skills among them. However, very little data are available in the literature highlighting the long-term impact of these training. Aims: To evaluate the impact of formal certified CPR training program on the knowledge and skill of CPR among nurses, to identify self-reported outcomes of attempted CPR and training needs of nurses. Setting and Design : Tertiary care hospital, Prospective, repeated-measures design. Subjects and Methods: A series of certified BLS and ACLS training programs were conducted during 2010 and 2011. Written and practical performance tests were done. Final testing was undertaken 3-4 years after training. The sample included all available, willing CPR certified nurses and experience matched CPR noncertified nurses. Statistical Analysis Used: SPSS for Windows version 21.0. Results: The majority of the 206 nurses (93 CPR certified and 113 noncertified were females. There was a statistically significant increase in mean knowledge level and overall performance before and after the formal certified CPR training program (P = 0.000. However, the mean knowledge scores were equivalent among the CPR certified and noncertified nurses, although the certified nurses scored a higher mean score (P = 0.140. Conclusions: Formal certified CPR training program increases CPR knowledge and skill. However, significant long-term effects could not be found. There is a need for regular and periodic recertification.

    Full Text Available Introduction: Modulating the stress response and perioperative factors can have a paramount impact on the neurodevelopmental outcome of infants who undergo cardiac surgery utilizing cardiopulmonary bypass. Materials and Methods: In this single center prospective follow-up study, we evaluated the impact of three different anesthetic techniques on the neurodevelopmental outcomes of 19 children who previously underwent congenital cardiac surgery within their 1 st year of life. Cases were done from May 2011 to December 2013. Children were assessed using the Stanford-Binet Intelligence Scales (5 th edition. Multiple regression analysis was used to test different parental and perioperative factors that could significantly predict the different neurodevelopmental outcomes in the entire cohort of patients. Results: When comparing the three groups regarding the major cognitive scores, a high-dose fentanyl (HDF patients scored significantly higher than the low-dose fentanyl (LDF + dexmedetomidine (DEX (LDF + DEX group in the quantitative reasoning scores (106 ± 22 vs. 82 ± 15 P = 0.046. The bispectral index (BIS value at the end of surgery for the -LDF group was significantly higher than that in LDF + DEX group (P = 0.011. For the entire cohort, a strong correlation was seen between the standard verbal intelligence quotient (IQ score and the baseline adrenocorticotropic hormone level, the interleukin-6 level at the end of surgery and the BIS value at the end of the procedure with an R 2 value of 0.67 and P < 0.04. There was an inverse correlation between the cardiac Intensive Care Unit length of stay and the full-scale IQ score (R = 0.4675 and P 0.027. Conclusions: Patients in the HDF group demonstrated overall higher neurodevelopmental scores, although it did not reach statistical significance except in fluid reasoning scores. Our results may point to a possible correlation between blunting the stress response and improvement of the neurodevelopmental

    The purpose of this study was to investigate cardiopulmonary responses to supine cycling with concomitant +G(sub z) acceleration using the NASA/Ames Human Powered Short-Arm Centrifuge (HPC). Subjects were eight consenting males (32+/-5 yrs, 178+/-5 cm, 86.1+/- 6.2 kg). All subjects completed two maximal exercise tests on the HPC (with and without acceleration) within a three-day period. A two tailed t-test with statistical significance set at p less than or equal to 0.05 was used to compare treatments. Peak acceleration was 3.4+/-0.1 G(sub z), (head to foot acceleration). Peak oxygen uptake (VO2(sub peak) was not different between treatment groups (3.1+/-0.1 Lmin(exp -1) vs. 3.2+/-0.1 Lmin(exp -1) for stationary and acceleration trials, respectively). Peak HR and pulmonary minute ventilation (V(sub E(sub BTPS))) were significantly elevated (p less than or equal to 0.05) for the acceleration trial (182+/-3 BPM (Beats per Minute); 132.0+/-9.0 Lmin(exp -1)) when compared to the stationary trial (175+/-3 BPM; 115.5+/-8.5 Lmin(exp -1)). Ventilatory threshold expressed as a percent of VO2(sub peak) was not different for acceleration and stationary trials (72+/-2% vs. 68+/-2% respectively). Results suggest that 3.4 G(sub z) acceleration does not alter VO2(sub peak) response to supine cycling. However, peak HR and V(sub E(sub BTPS)) response may be increased while ventilatory threshold response expressed as a function of percent VO2(sub peak) is relatively unaffected. Thus, traditional exercise prescription based on VO2 response would be appropriate for this mode of exercise. Prescriptions based on HR response may require modification.

  2. Strategies to prevent intraoperative lung injury during cardiopulmonary bypass

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Abstract During open heart surgery the influence of a series of factors such as cardiopulmonary bypass (CPB, hypothermia, operation and anaesthesia, as well as medication and transfusion can cause a diffuse trauma in the lungs. This injury leads mostly to a postoperative interstitial pulmonary oedema and abnormal gas exchange. Substantial improvements in all of the above mentioned factors may lead to a better lung function postoperatively. By avoiding CPB, reducing its time, or by minimizing the extracorporeal surface area with the use of miniaturized circuits of CPB, beneficial effects on lung function are reported. In addition, replacement of circuit surface with biocompatible surfaces like heparin-coated, and material-independent sources of blood activation, a better postoperative lung function is observed. Meticulous myocardial protection by using hypothermia and cardioplegia methods during ischemia and reperfusion remain one of the cornerstones of postoperative lung function. The partial restoration of pulmonary artery perfusion during CPB possibly contributes to prevent pulmonary ischemia and lung dysfunction. Using medication such as corticosteroids and aprotinin, which protect the lungs during CPB, and leukocyte depletion filters for operations expected to exceed 90 minutes in CPB-time appear to be protective against the toxic impact of CPB in the lungs. The newer methods of ultrafiltration used to scavenge pro-inflammatory factors seem to be protective for the lung function. In a similar way, reducing the use of cardiotomy suction device, as well as the contact-time between free blood and pericardium, it is expected that the postoperative lung function will be improved.

    For more than a decade, mild induced hypothermia (32 °C-34 °C) has been standard of care for patients remaining comatose after resuscitation from out-of-hospital cardiac arrest with an initial shockable rhythm, and this has been extrapolated to survivors of cardiac arrest with initially nonshockable rhythms and to patients with in-hospital cardiac arrest. Two randomized trials published in 2002 reported a survival and neurological benefit with mild induced hypothermia. One recent randomized trial reported similar outcomes in patients treated with targeted temperature management at either 33 °C or 36 °C. In response to these new data, the International Liaison Committee on Resuscitation Advanced Life Support Task Force performed a systematic review to evaluate 3 key questions: (1) Should mild induced hypothermia (or some form of targeted temperature management) be used in comatose post-cardiac arrest patients? (2) If used, what is the ideal timing of the intervention? (3) If used, what is the ideal duration of the intervention? The task force used Grading of Recommendations Assessment, Development and Evaluation methodology to assess and summarize the evidence and to provide a consensus on science statement and treatment recommendations. The task force recommends targeted temperature management for adults with out-of-hospital cardiac arrest with an initial shockable rhythm at a constant temperature between 32 °C and 36 °C for at least 24 hours. Similar suggestions are made for out-of-hospital cardiac arrest with a nonshockable rhythm and in-hospital cardiac arrest. The task force recommends against prehospital cooling with rapid infusion of large volumes of cold intravenous fluid. Additional and specific recommendations are provided in the document.

    Full Text Available The basic variants of cytokines reactions defining type of organ dysfunctions are revealed in the course of car- diopulmonary bypass and in the early postoperative period. Their character and expression, depends on gravity preoperative an immunodeficiency and initial degree of heart insufficiency. Diphasic dynamics of development of system inflammatory reaction is confirmed after cardiopulmonary bypass: increase of levels proinflammatory cytokines is in the first phase and anti-inflammatory cytokines with development immunodepression and cellular anergy in is the second phase. Also, key role IL-1Ra is revealed in restraint of hyperactivation of system inflam- matory reaction. Blood whey levels IL-6, IL-8, G-CSF, TNF-α and IL-1Ra should be defined to cardiopulmonary bypass, in 10–12 hours, 24 hours and 3 days after cardiopulmonary bypass and may be used as prognostic criteria of development of postoperative complications.

    2016-04-01

    Full Text Available Cardiopulmonary bypass causes an inflammatory response and consumption of coagulation factors, increasing the risk of bleeding and neurological and renal complications. Its use during lung transplantation may be due to pulmonary hypertension or associated cardiac defects or just for better exposure of the pulmonary hilum. We describe a simple technique, or open pericardium retraction, to improve hilar exposure by lifting the heart by upward retraction of the pericardial sac. This technique permits lung transplantation without cardiopulmonary bypass when bypass use is recommended only for better exposure.

    2009-07-01

    Full Text Available Abstract Background Hands-Only cardiopulmonary resuscitation (CPR is recommended for use on adult victims of witnessed out-of-hospital (OOH sudden cardiac arrest or in instances where rescuers cannot perform ventilations while maintaining minimally interrupted quality compressions. Promotion of Hands-Only CPR should improve the incidence of bystander CPR and, subsequently, survival from OOH cardiac arrest; but, little is known about a rescuer's ability to deliver continuous chest compressions of adequate rate and depth for periods typical of emergency services response time. This study evaluated chest compression rate and depth as subjects performed Hands-Only CPR for 10 minutes. For comparison purposes, each also performed chest compressions with ventilations (30:2 CPR. It also evaluated fatigue and changes in body biomechanics associated with each type of CPR. Methods Twenty healthy female volunteers certified in basic life support performed Hands-Only CPR and 30:2 CPR on a manikin. A mixed model repeated measures cross-over design evaluated chest compression rate and depth, changes in fatigue (chest compression force, perceived exertion, and blood lactate level, and changes in electromyography and joint kinetics and kinematics. Results All subjects completed 10 minutes of 30:2 CPR; but, only 17 completed 10 minutes of Hands-Only CPR. Rate, average depth, percentage at least 38 millimeters deep, and force of compressions were significantly lower in Hands-Only CPR than in 30:2 CPR. Rates were maintained; but, compression depth and force declined significantly from beginning to end CPR with most decrement occurring in the first two minutes. Perceived effort and joint torque changes were significantly greater in Hands-Only CPR. Performance was not influenced by age. Conclusion Hands-Only CPR required greater effort and was harder to sustain than 30:2 CPR. It is not known whether the observed greater decrement in chest compression depth associated

METHOD: We prospectively studied a hundred consecutive, no randomized patients, with age > or = 70 years, submitted to the primary and isolated myocardial revascularization between January and December of 2000. The patients were divided in two groups, G1 - 50 patients operated with CPB and G2 - 50 patients operated without CPB. Univariate testing of variables was performed with chi-squared analysis in the SPSS 10.0 Program and a p value less than 0.005 was considered significant. RESULTS: There was no renal failure or myocardial infarction (MI in both groups; the incidence of respiratory failure was identical in the two groups (4%; two patient of G1 they had Strokes, and 12 presented low output syndrome, occurrences not registered in G2. The need of ventilatory support > 24 hs was not significant between groups. Medium time of hospital stay was 21.8 and 11.7 days respectively (NS and the survival after 30 days were similar in the two groups. The patients' of G1 eighty percent had more than two approached arteries, against only 48% of G2 (p < 0.0001. CONCLUSION: Because the largest number of grafts in the patients of G1, we can affirm that the use of CPB can provide a larger probability of complete RM.

RESULTS: The results revealed a decrease in the systolic blood pressure and in the heart rate of those who did exercise as opposed to those who did not do exercise in Group I. In addition, R wave height in V6 of exercise group showed a statistically significant increase. As for second group, it was determined that the R/S, at V1 derivation obtained from the participants who did exercise showed a statistically decrease as compared to those of the participants who did not do exercise. In the third group, no changes were observed in the systolic blood pressure the heart rate, R wave height in V6 and R/S although the measures of PWC 170 test, VC and FVC obtained from all training groups made a significant increase when compared to those of control groups. CONCLUSION: The results of this study revealed that of the three groups the 15–17 age group was affected mostly by the aerobic exercise on kardiyopulmoner sytem. The results

    Cataglyphis cursor worker ants are capable of highly sophisticated rescue behaviour in which individuals are able to identify what has trapped a nestmate and to direct their behaviour towards that obstacle. Nonetheless, rescue behaviour is constrained by workers' subcaste: whereas foragers, the oldest workers, are able both to give and to receive the most help, the youngest workers, inactives, neither give nor receive any help whatsoever; nurses give and receive intermediate levels of aid, reflecting their intermediate age. Such differences in rescue behaviour across subcastes suggest that age and experience play a critical role. In this species, as in many others in which a sensitive period for nestmate recognition exists, newly enclosed ants, called callows, are adopted by ants belonging not only to different colonies but also to different species; foreign callows receive nearly the same special care provided to resident newborns. Because callows are younger than inactives, which are incapable of soliciting rescue, we wondered whether entrapped callows would receive such aid. In the present study, we artificially ensnared individual callows from their own colony (homocolonial), from a different colony (heterocolonial), and from a different species (heterospecific), and tested each one with groups of five potential C. cursor rescuers, either all foragers or all nurses. Our results show that all three types of callows are able to elicit rescue behaviour from both foragers and nurses. Nonetheless, nurse rescuers are better able to discriminate between the three types of callow victims than are foragers. PMID:26846232

    Sandia National Laboratories (Sandia) has a long history in developing compact, mobile, very high-speed drilling systems and this technology could be applied to increasing the rate at which boreholes are drilled during a mine accident response. The present study reviews current technical approaches, primarily based on technology developed under other programs, analyzes mine rescue specific requirements to develop a conceptual mine rescue drilling approach, and finally, proposes development of a phased mine rescue drilling system (MRDS) that accomplishes (1) development of rapid drilling MRDS equipment; (2) structuring improved web communication through the Mine Safety & Health Administration (MSHA) web site; (3) development of an improved protocol for employment of existing drilling technology in emergencies; (4) deployment of advanced technologies to complement mine rescue drilling operations during emergency events; and (5) preliminary discussion of potential future technology development of specialized MRDS equipment. This phased approach allows for rapid fielding of a basic system for improved rescue drilling, with the ability to improve the system over time at a reasonable cost.

  17. Closed-loop control for cardiopulmonary management and intensive care unit sedation using digital imaging

    Science.gov (United States)

    Gholami, Behnood

    This dissertation introduces a new problem in the delivery of healthcare, which could result in lower cost and a higher quality of medical care as compared to the current healthcare practice. In particular, a framework is developed for sedation and cardiopulmonary management for patients in the intensive care unit. A method is introduced to automatically detect pain and agitation in nonverbal patients, specifically in sedated patients in the intensive care unit, using their facial expressions. Furthermore, deterministic as well as probabilistic expert systems are developed to suggest the appropriate drug dose based on patient sedation level. Patients in the intensive care unit who require mechanical ventilation due to acute respiratory failure also frequently require the administration of sedative agents. The need for sedation arises both from patient anxiety due to the loss of personal control and the unfamiliar and intrusive environment of the intensive care unit, and also due to pain or other variants of noxious stimuli. In this dissertation, we develop a rule-based expert system for cardiopulmonary management and intensive care unit sedation. Furthermore, we use probability theory to quantify uncertainty and to extend the proposed rule-based expert system to deal with more realistic situations. Pain assessment in patients who are unable to verbally communicate is a challenging problem. The fundamental limitations in pain assessment stem from subjective assessment criteria, rather than quantifiable, measurable data. The relevance vector machine (RVM) classification technique is a Bayesian extension of the support vector machine (SVM) algorithm which achieves comparable performance to SVM while providing posterior probabilities for class memberships and a sparser model. In this dissertation, we use the RVM classification technique to distinguish pain from non-pain as well as assess pain intensity levels. We also correlate our results with the pain intensity

    The objective of this prospective study was to assess the incidence and magnitude of fat emboli after cardiopulmonary resuscitation and intraosseous infusions. An animal laboratory at a university center was used to study 33 mixed-breed piglets. The piglets underwent hypoxic cardiac arrest followed by chest compressions and mechanical ventilation for a minimum of 30 minutes. The animals were divided in groups: group 1 (n = 5), which had no intraosseous cannulas, group 2 (n = 6), which had intraosseous cannulas with infusion, groups 3 (n = 6), 4 (n = 6), and 5 (n = 8), which had intraosseous cannulas with infusion of epinephrine, normal saline, and sodium bicarbonate respectively, and group 6 (n = 2), which was a sham group with no intraosseous cannulas and no cardiopulmonary resuscitation. At cessation of cardiopulmonary resuscitation, representative lung samples were collected from upper and lower lobes of each lung and observed for fat globules and bone marrow elements. Fat globules were seen in the peribronchial blood vessels and intravascular areas throughout all lung fields of groups 1 through 5. There was no difference in appearance or distribution of fat globules among the 5 treatment groups. Analysis of variance showed no statistical significance (P fat embolization over cardiopulmonary resuscitation alone in this animal model. The benefits of using this procedure in critically ill children as a means of rapid vascular access for resuscitation is well established. However, the risk of fat embolism in this population needs further study. PMID:9258208

  7. Measurement and analysis of cardiopulmonary vascular in Lanzhou healthy adults with multislice spiral CT

    International Nuclear Information System (INIS)

    Objective: To constitute a normal standard of cardiopulmonary vascular diameter and size of normal adult in Lanzhou, and to compared with the other's data reported in the previous bibliography by measuring diameter and area of cardiopulmonary artery lumen of the healthy adults in Lanzhou with multislice spiral CT (MSCT). Methods: Three hundred Lanzhou adults with no cardiopulmonary disease were equally assigned to 3 groups according to their age (A group: 18-39 years, B group: 40-60 years, C group: 61-80 years; 50 females and 50 males in each group). CT data were acquired at the end of deep inspiration phase and measurements were done on 3D reconstruction image with precise landmarks. All the results were statistically analyzed. Results: The diameters and areas of the main pulmonary artery left pulmonary artery right pulmonary artery ascending aorta and descending aorta differed significantly among the 3 groups (P<0.05). In groups B and C, there were significant differences in diameters and areas of pulmonary artery left pulmonary artery and right pulmonary between different genders (P<0.05). Conclusion: Imaging standard is provided for Lanzhou adult in early diagnosis of cardiopulmonary disease. The diameters and areas of main pulmonary artery left pulmonary artery and right pulmonary artery of Lanzhou healthy adults are different from that of other regions. It may be related to the geographical environment and the state of air pollution in Lanzhou. (authors)

    Shortness of breath associated with cardiorespiratory abnormalities and peripheral muscle discomfort are the major factors that limit exercise capacity in patients with chronic obstructive pulmonary disease (COPD and those with congestive heart failure (CHF. Both of these symptoms negatively impact on patients’ daily physical activity levels. In turn, poor daily physical activity is commonly associated with increased rates of morbidity and mortality. Cardiopulmonary rehabilitation programmes partially reverse muscle weakness and dysfunction and increase functional capacity in both COPD and CHF. However, benefits gained from participation in cardiopulmonary rehabilitation programmes are regressing soon after the completion of these programmes. Moreover, several barriers limit access and uptake of cardiopulmonary rehabilitation programmes by eligible patients. A potential solution to the underutilisation of cardiopulmonary rehabilitation is the implementation of tele-rehabilitation interventions at home using information and communications technologies. Thus, tele-rehabilitation may be useful to encourage and educate patients with COPD or CHF on how best to maintain and/or further enhance daily physical activity levels.

    The Remotely Piloted Aircraft Systems (RPAS) are becoming more and more powerful and innovative and they have an increased interest in civil applications, in particular, after natural hazard phenomena. The RPAS is useful in search and rescue missions in high mountain where scenarios are unfriendly and the use of helicopters is often not profitable. First, the unmanned configuration is safer because there is no hazards for human life that is not on board. Moreover, it is cheaper due to the use of electric propulsion instead of internal combustion engine and to its small dimensions and weights. Finally, the use of the RPAS is faster while the helicopter is often not available because is involved in other missions or it cannot be used if the search mission is in impervious scenario, such as forests with thick vegetation. For instance, the RPAS can be used after an avalanche when victims have little time to be saved before the death by hypothermia. In most conditions, the body maintains a healthy temperature. However, if it is exposed to cold temperatures, especially with a high cooling factor from wind and high humidity, for extended periods, the control mechanisms of the body may not be able to maintain a normal body temperature. When you lose more heat than the body can generate, it takes over hypothermia, defined as a body temperature below 35° C. Wet clothing, fall into cold water or not adequately cover themselves during the cold season, are all factors that can increase the chances of hypothermia. Signs and symptoms (tremor, slurred speech, breathing abnormally slow, cold and pale skin, loss of coordination, fatigue, lethargy or apathy, confusion or memory loss) usually develop slowly. People with hypothermia typically experience a gradual loss of mental acuity and physical capacity, and realize that you have need of emergency medical care. For these reasons, the use of an RPAS could be crucial for the survival of disappeared people in high mountain. In

    X-ray crystallographic structures of four p53 core-domain variants were determined in order to gain insights into the mechanisms by which certain second-site suppressor mutations rescue the function of a significant number of cancer mutations of the tumor suppressor protein p53. To gain insights into the mechanisms by which certain second-site suppressor mutations rescue the function of a significant number of cancer mutations of the tumor suppressor protein p53, X-ray crystallographic structures of four p53 core-domain variants were determined. These include an oncogenic mutant, V157F, two single-site suppressor mutants, N235K and N239Y, and the rescued cancer mutant V157F/N235K/N239Y. The V157F mutation substitutes a smaller hydrophobic valine with a larger hydrophobic phenylalanine within strand S4 of the hydrophobic core. The structure of this cancer mutant shows no gross structural changes in the overall fold of the p53 core domain, only minor rearrangements of side chains within the hydrophobic core of the protein. Based on biochemical analysis, these small local perturbations induce instability in the protein, increasing the free energy by 3.6 kcal mol{sup −1} (15.1 kJ mol{sup −1}). Further biochemical evidence shows that each suppressor mutation, N235K or N239Y, acts individually to restore thermodynamic stability to V157F and that both together are more effective than either alone. All rescued mutants were found to have wild-type DNA-binding activity when assessed at a permissive temperature, thus pointing to thermodynamic stability as the critical underlying variable. Interestingly, thermodynamic analysis shows that while N239Y demonstrates stabilization of the wild-type p53 core domain, N235K does not. These observations suggest distinct structural mechanisms of rescue. A new salt bridge between Lys235 and Glu198, found in both the N235K and rescued cancer mutant structures, suggests a rescue mechanism that relies on stabilizing the

    For as long as planes have gone down, dedicated men and women have used ever-improving technologies to aid their search for survivors. Nearly 2,000 general aviation crashes occur each year in U.S.-and many, like the Montana incident, occur without witnesses. On average, every day in the U.S. one airplane is reported missing. The Air Force Rescue Coordination Center (AFRCC) organizes search missions for about 100 aircraft each year. Some of these are not found before the searches called off, and are discovered only by chance long after the crash. In some cases, the crash site is never found. NASA Search and Rescue Mission is using NCCS rescues to develop tools for processing radar data that can help these effort

    Objective To study if using autologous lung as a substitute of oxygenator in cardiopulmonary bypass is better than the conventional cardiopulmonary bypass with artificial oxygenator in pulmonary preservation.Methods Twelve piglets were randomly divided into two groups ( n = 6). The isolated lung perfusion model was established. The experimental animals underwent continuous lung perfusion for about 120 min. While the control animals underwent 90 min lung ischemia followed by 30 min reperfusion. Another 12 piglets were randomly divided into two groups ( n =6). The experimental animals underwent bi-ventricular bypass with autologous lung perfusion.While control animals underwent conventional cardiopulmonary bypass with artificial oxygenator. The bypass time and aortic cross clamping time were 135 min and 60 min respectively for each animal. The lung static compliance ( Cstat), alveolus-artery oxygen difference ( PA-aO2 ), TNF-α, IL-6 and wet to dry lung weight ratio (W/D) were measured. Histological and ultra-structural changes of the lung were also observed after bypass. Results After either isolated lung perfusion or cardiopulmonary bypass, the Cstat decreased, the PA-aO2 increased and the content of TNF-α increased for both groups, but the changes of experimental group were much less than those of control group. The lower W/D ratio and mild pathological changes in experimental group than those in control group were also demonstrated. Conclusion Autologous lung is able to tolerate the nonpalsatile perfusion. It can be used as a substitute to artificial ogygenator in cardiopulmonary bypass to minimize the inflammatory pulmonary injury caused mainly by ischemic reperfusion and interaction of the blood to the non-physiological surface of artificial oxygenator.

    Full Text Available Abstract Background Neurologic deficits after cardiac surgery are common complications. Aim of this prospective observational pilot study was to investigate the incidence of postoperative cognitive deficit (POCD after cardiac surgery, provided that relevant decrease of cerebral oxygen saturation (cSO2 is avoided during cardiopulmonary bypass. Methods cSO2 was measured by near infrared spectroscopy in 35 patients during cardiopulmonary bypass. cSO2 was kept above 80% of baseline and above 55% during anesthesia including cardiopulmonary bypass. POCD was tested by trail making test, digit symbol substitution test, Ray's auditorial verbal learning test, digit span test and verbal fluency test the day before and 5 days after surgery. POCD was defined as a decline in test performance that exceeded - 20% from baseline in two tests or more. Correlation of POCD with lowest cSO2 and cSO2 - threshold were determined explorative. Results POCD was observed in 43% of patients. Lowest cSO2 during cardiopulmonary bypass was significantly correlated with POCD (p = 0.015, r2 = 0.44, without Bonferroni correction. A threshold of 65% for cSO2 was able to predict POCD with a sensitivity of 86.7% and a specificity of 65.0% (p = 0.03, without Bonferroni correction. Conclusions Despite a relevant decrease of cerebral oxygen saturation was avoided in our pilot study during cardiopulmonary bypass, incidence of POCD was comparable to that reported in patients without monitoring. A higher threshold for cSO2 may be needed to reduce the incidence of POCD.

The 32 rabbits were randomly divided into sham-operated group (n=8),conventional resuscitation group (n=12) and Batroxobin-treated group (n=12). The animals in the conventional resuscitation group and Batroxobin-treated group were anesthetized, then induced into modified Pittsburg's model of mechanical ventricular fibrillation. Sham-operated group was discharged on the chest wall, which did not cause ventricular fibrillation. Conventional resuscitation group and Batroxobin-treated group were exposed to 6 minutes of cardiac arrest induced by ventricular fibrillation, then the resuscitation began. A dosage of 0.3 Bu/kg of Batroxobin was administered to the rabbits in the Batroxobin-treated group at the beginning of resuscitation. Blood sample was collected at 4 and 12 hours after CPR to determine the concentration of TNF- α in serum. After the second blood collection, brain tissue was taken out immediately,and the forms of nerve cells in cerebral cortex and hippocampal CA1 region were observed under light microscope.MAIN OUTCOME MEASURES: ① TNF-α concentration in

With the pursuit of this technological achievement, the ability to care for mankind in the areas of cardiac surgery has been made possible. Heart disease can affect anyone within the general population, but one such segment that it can affect from inception includes children. Currently, congenital heart defects are the most common birth defects nationally and worldwide. A large meta-analysis study from 1930 to 2010 was conducted in review of published medical literature totaling 114 papers with a study population of 24,091,867 live births, and divulged a staggering incidence of congenital heart disease involving 164,396 subjects with diverse cardiac illnesses. The prevalence of these diseases increased from 0.6 per 1,000 live births from 1930–1934 to 9.1 per 1,000 live births after 1995. These data reveal an emphasis on a growing public health issue regarding congenital heart disease. This discovery displays a need for heightened awareness in the scientific and medical industrial community to accelerate investigative research on emerging cardiovascular devices in an effort to confront congenital anomalies. One such device that has evolved over the past several decades is the pediatric membrane oxygenator. The pediatric membrane oxygenator, in conjunction with the heart lung

    Full Text Available Apoptosis triggered by exogenous or endogenous stimuli is a crucial phenomenon to determine the fate of neurons, both in physiological and in pathological conditions. Our previous study established that gastric inhibitory polypeptide (Gip is a neurotrophic factor capable of preventing apoptosis of cerebellar granule neurons (CGNs, during its pre-commitment phase. In the present study, we conducted whole-genome expression profiling to obtain a comprehensive view of the transcriptional program underlying the rescue effect of Gip in CGNs. By using DNA microarray technology, we identified 65 genes, we named survival related genes, whose expression is significantly de-regulated following Gip treatment. The expression levels of six transcripts were confirmed by real-time quantitative polymerase chain reaction. The proteins encoded by the survival related genes are functionally grouped in the following categories: signal transduction, transcription, cell cycle, chromatin remodeling, cell death, antioxidant activity, ubiquitination, metabolism and cytoskeletal organization. Our data outline that Gip supports CGNs rescue via a molecular framework, orchestrated by a wide spectrum of gene actors, which propagate survival signals and support neuronal viability.

    Full Text Available The unprecedented scale and number of natural and man-made disasters in the past decade has urged international emergency search and rescue communities to seek for novel technology to enhance operation efficiency. Tele-operated search and rescue robots that can navigate deep into rubble to search for victims and to transfer critical field data back to the control console has gained much interest among emergency response institutions. In response to this need, a low-cost autonomous mini robot equipped with thermal sensor, accelerometer, sonar, pin-hole camera, microphone, ultra-bright LED and wireless communication module is developed to study the control of a group of decentralized mini search and rescue robots. The robot can navigate autonomously between voids to look for living body heat and can send back audio and video information to allow the operator to determine if the found object is a living human. This paper introduces the design and control of a low-cost robotic search and rescue system based on an immuno control framework developed for controlling decentralized systems. Design and development of the physical prototype and the immunity-based control system are described in this paper.

    2016-02-01

    There is little information regarding concordance between preferences for end-of-life care of terminally ill patients with cancer and those of their family caregivers. A cross-sectional exploration of cardiopulmonary resuscitation (CPR) preference in 361 dyads was conducted. Patients or family caregivers who were willing to approve CPR were compared with dyads who did not support CPR. The patient's quality of life was more associated with family caregiver's willingness than patient's willingness. A patient was more likely to prefer CPR than their caregiver in dyads of females and emotionally stable patients. A family caregiver showed stronger support for CPR if the patient had controlled pain or stable health and the family caregiver had not been counseled for CPR. Communications should be focused on these individuals to improve the planning of end-of-life care. PMID:25138648

    2015-05-01

    Full Text Available Emergency rescue after an earthquake is complex work which requires the participation of relief and social organizations. Studying earthquake emergency coordination efficiency can not only help rescue organizations to define their own rescue missions, but also strengthens inter-organizational communication and collaboration tasks, improves the efficiency of emergency rescue, and reduces loss. In this paper, collaborative entropy is introduced to study earthquake emergency rescue operations. To study the emergency rescue coordination relationship, collaborative matrices and collaborative entropy functions are established between emergency relief work and relief organizations, and the collaborative efficiency of the emergency rescue elements is determined based on this entropy function. Finally, the Lushan earthquake is used as an example to evaluate earthquake emergency rescue coordination efficiency.

    2011-01-01

    As the first Space Shuttle launch was still in our future, many from NASA, the Department of Defense (DoD) and NASA contractors were busy planning for not only a nominal launch and return, but contingency operations at the launch pad and landing sites. Prior to the first launch, detailed coordination, planning and simulations were conducted at all three locations and internal rescue procedures were taught at Kennedy Space Center (KSC). Later in the Program, the Transoceanic Abort Landing (TAL) sites were added in Europe and Africa. For the 51L mission a new TAL site was brought on line in Morocco. However, upon launch, the Shuttle Program experienced it's first lost. During the following months a complete review of all contingency operations (launch and landing) was completed. Many enhancements were made based on the reviews following. A Mode VIII water rescue was developed for NASA by the DoD before the STS-26 launch. Different concepts were explored and being debated by NASA. Training of the contingency forces was required before final decisions were made forcing the teaching of two different sets of procedures. To assist with training, a video was developed for the fire/crash/rescue personnel. This accompanied the detailed extraction procedures that were developed by a combination of KSC and DoD firemen. Training for the fire/crash/rescue personnel at Vandenberg AFB was also being planned before the accident happen. The fire/crash/rescue mockup that was being built at Chanute AFB was diverted to Edwards AFB. Educational Objectives: With the emphasis on Commercial Crew Programs for Space flight it is important that all involved understand what is required to prepare for contingencies. Cost effective means of being prepared for contingencies are needed. Questions: 1. When should planning for nominal and contingency operations begin? 2. What type of training aids are needed for contingency operations? 3. Who were the major contributors to Shuttle contingency

    Full Text Available Over the past century, there were more than 40 earthquakes greater than 7 magnitude occurred worldwide, 10 of which in China, which killed 600 thousand people accounting for 53% of global earthquake deaths. On May 12, 2008, an 8.0-magnitude earthquake occurred in Wenchuan, Sichuan Province, causing 69000 deaths, 18000 missings, and 370000 injuries. Among 10 thousand severe injuries, most were traumatic injuries, 74% of which were fracture. On April 14, 2010, a 7.1-magnitude earthquake occurred in Yushu, Qinghai Province. There were 2698 deaths, 270 missings and 11000 injuries. Among 3100 severe injuries, fracture accounted for 58.4%. After each earthquake, the Chinese Army Medical Services took actions and made quick response according to the law. They sent out elites with efficient command and scientific organization, fully participating in the medical rescue operations. After Wenchuan earthquake, 397 mobile medical service units and 7061 health workers were sent out. A total of 69000 people were treated, and 22000 cases of surgeries were performed. After Yushu earthquake, a total of 25 mobile medical service units and 2025 health workers were sent. They performed 1635 cases of surgeries with a miracle of "zero death" in mass earthquake casualties and altitude diseases in cold highlands. After each earthquake, injuries cured within 1 week accounted for 60% of the total, and patients evacuated accounted for 80% of the total, which owed to the effective first aid in site of Chinese Army Medical Service. They effectively played the role as the main force, making significant contributions for the final victory of earthquake relief. From the practice of medical rescue revelation after the two earthquakes, what Chinese Army Medical Services Services learned are: firstly, the theory of medical relief should be innovated; secondly, military and civilian organizations should be coordinated; thirdly, professional rescue force should be strengthened

    Frequent natural disasters and man-made catastrophes have threatened the safety of citizens and have attracted much more attention. The rescue mission under disaster environment is very complicated and dangerous for a rescue team. Search and rescue (SAR) robots can not only improve the efficiency of rescue operations but also reduce the casualty of rescuers. Robots can help rescue teams and even replace rescuers to perform dangerous missions. Search and rescue robots will play a more and more important role in the rescue operations. A survey of the research status of search and rescue robots in Japan, USA, China and other countries has been provided. According to current research,experiences and the lessons learned from applications, the five key performances of a search and rescue robot are survivability, mobility, sensing, communicability and operability.Multi-technique fusion and multi-agent intelligent network are considered to be requirements for the future development of the search and rescue robot. Disaster prevention, disaster reduction and disaster rescue are the important parts of national public safety. They are also crucial for the safety of citizens and their estates. Search and rescue robotic technique is an urgent needed, strategic and core technique for national development. It will be important and strategic for national economy and safety.

    Determination of an 'anaerobic threshold' plays an important role in the appreciation of an incremental cardiopulmonary exercise test and describes prominent changes of blood lactate accumulation with increasing workload. Two lactate thresholds are discerned during cardiopulmonary exercise testing and used for physical fitness estimation or training prescription. A multitude of different terms are, however, found in the literature describing the two thresholds. Furthermore, the term 'anaerobic threshold' is synonymously used for both, the 'first' and the 'second' lactate threshold, bearing a great potential of confusion. The aim of this review is therefore to order terms, present threshold concepts, and describe methods for lactate threshold determination using a three-phase model with reference to the historical and physiological background to facilitate the practical application of the term 'anaerobic threshold'.

    2015-07-01

    Tension pneumothorax can occur at any time during cardiopulmonary resuscitation (CPR) with external cardiac massage and invasive ventilation either from primary or iatrogenic rib fractures with concomitant pleural or parenchymal injury. Airway injury can also cause tension pneumothorax during CPR. This article presents the case of a 41-year-old woman who suffered cardiopulmonary arrest after undergoing elective mandibular surgery. During CPR the upper airway could not be secured by orotracheal intubation due to massive craniofacial soft tissue swelling. A surgical airway was established with obviously unrecognized iatrogenic tracheal perforation and subsequent development of tension pneumomediastinum and tension pneumothorax during ventilation. Neither the tension pneumomediastinum nor the tension pneumothorax were decompressed and accordingly resuscitation efforts remained unsuccessful. This case illustrates the need for a structured approach to resuscitate patients with ventilation problems regarding decompression of tension pneumomediastinum and/or tension pneumothorax during CPR.

    2016-06-01

    Here, we present a case of a deceased-donor kidney transplant. The brain-dead donor had received a massive blood transfusion during cardiopulmonary bypass, which lead to hemolysis, hemoglobinuria, acute kidney injury, and renal replacement therapy. The kidney appeared red after in situ flush. Postoperatively, the recipient developed delayed graft function. Protocol biopsy during the postoperative period revealed the widespread deposition of heme pigment in the renal tubules. Massive blood transfusion and cardiopulmonary bypass surgery are associated with hemolysis and heme pigment deposition in the renal tubules, which subsequently lead to acute kidney injury. Kidneys from such donors appear red and, while this does not preclude transplant, are likely to develop delayed graft function. PMID:26030717

    International Nuclear Information System (INIS)

    Twenty dogs exposed by inhalation in the study, Toxicity of Inhaled 239PuO2 in Beagle Dogs, were evaluated for cardiopulmonary function. Another group of 10 dogs matched by age and sex, but not exposed to 239Pu, was also given the same cardiopulmonary function tests. The plutonium-exposed dogs were 7 or more years after exposure and ten of the dogs had clinical signs and pulmonary function values indicating radiation pneumonitis-pulmonary fibrosis. The occurrence of radiation pneumonitis-pulmonary fibrosis, a nonstochastic effect, over the same time period and range of lung doses as lung cancer, a stochastic effect, complicates the estimation of lung cancer risk for inhaled plutonium. 4 references, 4 figures, 2 tables

  11. Study on the radioactive monitoring and protection related to maritime rescue and salvage operations under the conditions of nuclear contamination

    International Nuclear Information System (INIS)

    Once the vessel, which is related to nuclear, wreck at sea resulting in radiation leakage or sinking, it will most likely lead to full-accident area, a wide range radioactive pollution. When emergency rescue or post-salvage is taken, rescue personnel will inevitably cause radioactive damage. To ensure the minimum radiation dose of salvage personnel and smooth salvage mission, series of questions, such as prior evaluation and real-time monitoring of the underwater nuclear radiation field, radiation protection, pollution control and evaluation of radiation doses of salvage personnel, must be resolved. For the problems in the process of salvage of vessels which are occurred radiation leakage at sea, research problems needed to solve, methods and advances are proposed, and provide support for the solution of the problems related to the salvage operations under the conditions of radioactive contamination at sea.

    The usefulness of using the bispectral index (BIS) for monitoring during cardiopulmonary resuscitation (CPR) is not clearly understood. However, BIS has been a popular anesthetic monitoring device used during operations. The case presented is of a pregnant woman going into cardiac arrest due to an amniotic fluid embolism during a Cesarean section. CPR was performed, but neither the return of spontaneous circulation (ROSC) nor the return of consciousness was achieved, despite 50 min of effecti...

    2016-01-01

    High-quality cardiopulmonary resuscitation (CPR) has been shown to improve survival outcomes after cardiac arrest. The current standard in studies evaluating CPR quality is to measure CPR process measures—for example, chest compression rate, depth, and fraction. Published studies evaluating CPR feedback devices have yielded mixed results. Newer approaches that seek to optimize CPR by measuring physiological endpoints during the resuscitation may lead to individualized patient care and improve...

    Many epidemiologic reports associate ambient levels of particulate matter (PM) with human mortality and morbidity, particularly in people with preexisting cardiopulmonary disease (e.g., chronic obstructive pulmonary disease, infection, asthma). Because much ambient PM is derived from combustion sources, we tested the hypothesis that the health effects of PM arise from anthropogenic PM that contains bioavailable transition metals. The PM samples studied derived from three emission sources (two...

    2016-01-01

    Lidocaine is commonly used in ruminants but has an anecdotal history of being toxic to goats. To evaluate lidocaine's effects on selected cardiopulmonary parameters. Isoflurane-anesthetized adult goats (n = 24) undergoing abdominal surgery received a loading dose of lidocaine (2.5 mg/kg) over 20 min followed by constant-rate infusion of lidocaine (100 μg/kg/min); control animals received saline instead of lidocaine. Data collected at predetermined time points during the 60-min surgery included heart rate, mean arterial blood pressure, pO2, and pCO2. According to Welch 2-sample t tests, cardiopulmonary variables did not differ between groups. For example, after administration of the loading dose, goats in the lidocaine group had a mean heart rate of 88 ± 28 bpm, mean arterial blood pressure of 70 ± 19 mm Hg, pCO2 of 65 ± 13 mm Hg, and pO2 of 212 ± 99 mm Hg; in the saline group, these values were 90 ± 16 bpm, 76 ± 12 mm Hg, 61 ± 9 mm Hg, and 209 ± 83 mm Hg, respectively. One goat in the saline group required an additional dose of butorphanol. Overall our findings indicate that, at the dose provided, intravenous lidocaine did not cause adverse cardiopulmonary effects in adult goats undergoing abdominal surgery. Adding lidocaine infusion during general anesthesia is an option for enhancing transoperative analgesia in goats. PMID:27423150

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    Full Text Available BACKGROUND: Patients with systemic sclerosis (SSc may develop exercise intolerance due to musculoskeletal involvement, restrictive lung disease, left ventricular dysfunction, or pulmonary vasculopathy (PV. The latter is particularly important since it may lead to lethal pulmonary arterial hypertension (PAH. We hypothesized that abnormalities during cardiopulmonary exercise testing (CPET in patients with SSc can identify PV leading to overt PAH. METHODS: Thirty SSc patients from the Harbor-UCLA Rheumatology clinic, not clinically suspected of having significant pulmonary vascular disease, were referred for this prospective study. Resting pulmonary function and exercise gas exchange were assessed, including peakVO2, anaerobic threshold (AT, heart rate-VO2 relationship (O2-pulse, exercise breathing reserve and parameters of ventilation-perfusion mismatching, as evidenced by elevated ventilatory equivalent for CO2 (VE/VCO2 and reduced end-tidal pCO2 (PETCO2 at the AT. RESULTS: Gas exchange patterns were abnormal in 16 pts with specific cardiopulmonary disease physiology: Eleven patients had findings consistent with PV, while five had findings consistent with left-ventricular dysfunction (LVD. Although both groups had low peak VO2 and AT, a higher VE/VCO2 at AT and decreasing PETCO2 during early exercise distinguished PV from LVD. CONCLUSIONS: Previously undiagnosed exercise impairments due to LVD or PV were common in our SSc patients. Cardiopulmonary exercise testing may help to differentiate and detect these disorders early in patients with SSc.

    Full Text Available Background: Prolonged mechanical ventilation is an important recognized complication occurring during cardiovascular surgery procedures. This study was done to assess the perioperative risk factors related to postoperative pulmonary complications and tracheostomy in women undergoing coronary artery bypass graft with cardiopulmonary bypass. Methods: It was a retrospective study on 5,497 patients, including 31 patients with prolonged ventilatory support and 5,466 patients without it; from the latter group, 350 patients with normal condition (extubated in 6-8 hours without any complication were selected randomly. Possible perioperative risk factors were compared between the two groups using a binary logistic regression model. Results: Among the 5,497 women undergoing coronary artery bypass graft (CABG, 31 women needed prolonged mechanical ventilation (PMV, and 15 underwent tracheostomy. After logistic regression, 7 factors were determined as being independent perioperative risk factors for PMV. Discussion: Age ≥70 years old, left ventricular ejection fraction (LVEF ≤30%, preexisting respiratory or renal disease, emergency or re-do operation and use of preoperative inotropic agents are the main risk factors determined in this study on women undergoing CABG.

    A recombinant human serine protease inhibitor known as Kunitz protease inhibitor (KPI) wild type has functional similarities to the bovine Kunitz inhibitor, aprotinin, and had shown a potential to reduce bleeding in an ovine model of cardiopulmonary bypass (CPB). The aim of this study was to assess KPI-185, a modification of KPI-wild type that differs from KPI-wild type in two amino acid residues and which enhances anti-kallikrein activity in a further double-blind, randomized study in an ovine model of CPB, and to compare with our previous study of KPI-wild type and aprotinin in the same ovine model. Post-operative drain losses and subjective assessment of wound 'dryness' showed no significant differences between KPI-185 and KPI-wild type, despite the significant enhancement of kallikrein inhibition using KPI-185 seen in serial kallikrein inhibition assays. These preliminary findings support the hypothesis that kallikrein inhibition is not the major mechanism by which Kunitz inhibitors such as aprotinin reduce perioperative bleeding. PMID:11419655

    Among the major cucurbit vegetables, melon (Cucumis melo) has one of the greatest polymorphic fruit types and botanical varieties. Some melon fruits have excellent aroma, variety of flesh colors, deeper flavor, and more juice compared to other cucurbits. Despite numerous available melon cultivars, some of them are exceedingly susceptible to several diseases. The genetic background carrying the genes for tolerance and/or resistance for those diseases is found in wild melon landraces. Unfortunately, the commercial melon varieties are not able to produce viable hybrids when crossed with their wild melon counterparts. Plant tissue culture techniques are needed to surpass those genetic barriers. In vitro melon embryo rescue has played a main role to obtain viable hybrids originated from commercial versus wild melon crosses. In this chapter, an efficient and simple embryo rescue melon protocol is thoroughly described. PMID:21207265

    Full Text Available OBJECTIVE: The 6-minute walk test is an way of assessing exercise capacity and predicting survival in heart failure. The 6-minute walk test was suggested to be similar to that of daily activities. We investigated the effect of motivation during the 6-minute walk test in heart failure. METHODS: We studied 12 males, age 45±12 years, ejection fraction 23±7%, and functional class III. Patients underwent the following tests: maximal cardiopulmonary exercise test on the treadmill (max, cardiopulmonary 6-minute walk test with the walking rhythm maintained between relatively easy and slightly tiring (levels 11 and 13 on the Borg scale (6EB, and cardiopulmonary 6-minute walk test using the usual recommendations (6RU. The 6EB and 6RU tests were performed on a treadmill with zero inclination and control of the velocity by the patient. RESULTS: The values obtained in the max, 6EB, and 6RU tests were, respectively, as follows: O2 consumption (ml.kg-1.min-1 15.4±1.8, 9.8±1.9 (60±10%, and 13.3±2.2 (90±10%; heart rate (bpm 142±12, 110±13 (77±9%, and 126±11 (89±7%; distance walked (m 733±147, 332±66, and 470±48; and respiratory exchange ratio (R 1.13±0.06, 0.9±0.06, and 1.06±0.12. Significant differences were observed in the values of the variables cited between the max and 6EB tests, the max and 6RU tests, and the 6EB and 6RU tests (p<0.05. CONCLUSION: Patients, who undergo the cardiopulmonary 6-minute walk test and are motivated to walk as much as they possibly can, usually walk almost to their maximum capacity, which may not correspond to that of their daily activities. The use of the Borg scale during the cardiopulmonary 6-minute walk test seems to better correspond to the metabolic demand of the usual activities in this group of patients.

    Full Text Available PURPOSE: Cardiopulmonary bypass is known to alter propofol pharmacokinetics in patients undergoing cardiac surgery. However, few studies have evaluated the impact of these alterations on postoperative pharmacodynamics. This study was designed to test the hypothesis that changes in propofol pharmacokinetics increase hypnotic effects after cardiopulmonary bypass. METHODS: Twenty patients scheduled for on-pump coronary artery bypass graft (group, n=10 or off-pump coronary artery bypass graft (group, n=10 coronary artery bypass grafts were anesthetized with sufentanil and a propofol target controlled infusion (2.0 µg/mL. Depth of hypnosis was monitored using the bispectral index. Blood samples were collected from the induction of anesthesia up to 12 hours after the end of propofol infusion, at predetermined intervals. Plasma propofol concentrations were measured using high-performance liquid chromatography, followed by a non-compartmental propofol pharmacokinetic analysis. Data were analyzed using ANOVA, considering p<0.05 as significant. RESULTS: After cardiopulmonary bypass, despite similar plasma propofol concentrations in both groups, bispectral index values were lower in the on-pump coronary artery bypass graft group. Time to extubation after the end of propofol infusion was greater in the on-pump coronary artery bypass graft group (334 ± 117 vs. 216 ± 85 min, p = 0.04. Patients undergoing cardiopulmonary bypass had shorter biological (1.82 ± 0.5 vs. 3.67 ± 1.15h, p < 0.01 and terminal elimination (6.27 ± 1.29 vs. 10.5h ± 2.18, p < 0.01 half-life values, as well as higher total plasma clearance (28.36 ± 11.40 vs.18.29 ± 7.67 mL/kg/min, p = 0.03, compared to patients in the off-pump coronary artery bypass graft group. CONCLUSION: Aside from the increased sensitivity of the brain to anesthetics after cardiopulmonary bypass, changes in propofol pharmacokinetics may contribute to its central nervous system effects.

  18. Vulture rescue and rehabilitation in South Africa: An urban perspective

    Full Text Available SouthAfrica is home to 9 vulture species, of which 7 are endangered. While the cause of the population declines remains largely speculative, a vast amount of effort has been dedicated towards the protection of populations by ensuring sustainable and safe food sources for the various colonies. Limited focus was placed in the past on efforts related to the rescue and/or rehabilitation (R&R of injured birds and the release of these birds back into the wild. This paper provides an overview of the causes, the impact and success of 3 organisations involved in R&R efforts of vultures in the Magaliesberg mountain range and surrounding areas over a period of 10 years. Study material included 162 Cape griffon (CGV and 38 African white-backed (AWBV vultures. Datasets include the number, sex and age of birds received, the reason the vultures were brought in for R&R, surgical interventions performed and outcomes of rescue efforts. The CGV dominated the rehabilitation attempts. Results further show that a large number of apparently healthy birds were presented for veterinary treatment. The R&R data clearly indicate that the major cause of injuries was birds colliding with overhead pylons, as a high number of soft tissue and skeletal injuries were observed. The study also shows that successful releases of rescued birds are possible. It is concluded that urbanisation has had a major negative impact on vultures around the Magaliesberg mountain range.

    The zebrafish represents a revolutionary tool in large-scale genetic and small-molecule screens for gene and drug discovery. Transgenic zebrafish are often utilized in these screens. Many transgenic fish lines are maintained in the heterozygous state due to the lethality associated with homozygosity; thus, their progeny must be sorted to ensure a population expressing the transgene of interest for use in screens. Sorting transgenic embryos under a fluorescence microscope is very labor-intensive and demands fine-tuned motor skills. Here we report an efficient transgenic method of utilizing pigmentation rescue of nacre mutant fish for accurate naked-eye identification of both mosaic founders and stable transgenic zebrafish. This was accomplished by co-injecting two constructs with the I-SceI meganuclease enzyme into pigmentless nacre embryos: I-SceI-mitfa:mitfa-I-SceI to rescue the pigmentation and I-SceI-zpromoter:gene-of-interest-I-SceI to express the gene of interest under a zebrafish promoter (zpromoter). Pigmentation rescue reliably predicted transgene integration. Compared with other transgenic techniques, our approach significantly increases the overall percentage of founders and facilitates accurate naked-eye identification of stable transgenic fish, greatly reducing laborious fluorescence microscope sorting and PCR genotyping. Thus, this approach is ideal for generating transgenic fish for large-scale screens. PMID:26757807

    From 2010 to 2012, large outbreaks of EV-A71-related- hand foot and mouth disease (HFMD) occurred annually in China. Some cases had neurological complications and were closely associated with fatal cardiopulmonary collapse, but not all children with central nervous system (CNS) involvement demonstrated a poor prognosis. To identify which patients and which neurological complications are more likely to progress to cardiopulmonary failure, we retrospectively studied 1,125 paediatric inpatients diagnosed with EV-A71-related HFMD in Hunan province, including 1,017 cases with CNS involvement. These patients were divided into cardiopulmonary failure (976 people) group and group without cardiopulmonary failure (149 people). A logistic regression analysis was used to compare the clinical symptoms, laboratory test results, and neurological complications between these two groups. The most significant risk factors included young age, fever duration ≥3 days, coma, limb weakness, drowsiness and ANS involvement. Patients with brainstem encephalitis and more CNS-involved regions were more likely to progress to cardiopulmonary failure. These findings can help front-line clinicians rapidly and accurately determine patient prognosis, thus rationally distributing the limited medical resources and implementing interventions as early as possible.

    2010-01-01

    Recently, there has been a growing interest of using network coding to support reliable unicast over an error-prone channel. However, previous network coding schemes focused only on native packets and ignored the role of encoded packets. In this paper, we develop an efficient retransmission approach with network coding method, namely Encoded packet-Assisted Rescue (EAR), which is able to overcome this limitation. Using the proposed network coding approach, clients store the overheard encoded packets and report to the sender. And then, when the sender makes coding decisions, it not only considers native packets, but also takes account of encoded packets. In this way, more coding opportunities are emerged, i.e. more packets can be mixed together, resulting in improving the retransmission efficiency. Moreover, theoretical analysis and simulation results show that comparing with the existing schemes, our schemes can greatly reduce the total number of retransmissions.

    SALVEREMO project aims at designing and prototyping an innovative system for searching and rescuing individuals (especially hikers and mountaineers) who got lost or in peril in wilderness or mountain areas. It makes use of Remotely Piloted Aircraft System (RPAS) equipped with a sensor suite specifically selected according to the requirements identified involving alpine rescuers and government officials. The peculiarity of the proposed solution is the exploitation and integration of the special skill and expertise coming from different competence fields. It will dramatically decrease the searching time in the wilderness and remote areas off the beaten tracks, providing rescuers and operators with a decision support system increasing successful results and reducing rescue missions costs. The system benefits from the adoption of a scaled-down Base Transceiver Station (BTS) embarked in the payload sensor suite of a small RPAS that can be carried in a back pack of rescuers. A Software Defined Radio (SDR) board implementing the BTS protocol stack has been integrated in a complex sensor suite made up of open processing boards and camera devices. Moreover computer vision (CV) algorithms for real time pattern detection and image enhancements have been investigated for assisting the rescuers during the searching operations. An easy-to-use ground station application has been developed for speeding up the overall mission accomplishment. Aknowledgement SALVEREMO project is a research project co-funded by Regione Piemonte according to the call for proposal POR F.E.S.R. 2007/2013, "Linea di attività I.1.3-Innovazione e PMI - Polo della Meccatronica e dei Sistemi Avanzati di Produzione".

    2009-01-01

    Full Text Available Abstract Background Glyphosate is an herbicide considered to be of low toxicity to humans because its effects are specific to plants. However, fatal reactions to glyphosate have been reported after the ingestion of large amounts. Pulmonary edema, shock, and arrhythmia were the reported causes of mortality. Case presentation We present the case of a 57-year-old woman who was admitted to the emergency department unconsciousness after ingestion of glyphosate surfactant in a suicide attempt. Metabolic acidosis, refractory respiratory failure, and shock developed during hospitalization. Despite aggressive supportive care, the patient died in the hospital. Conclusion The toxicokinetics of glyphosate surfactant is complicated. Respiratory failure, metabolic acidosis, tachycardia, elevated creatinine, and hyperkalemia are poor prognostic factors if presented. Physicians should consider using hemodialysis early to improve the outcome of patients with glyphosate surfactant intoxication.

  6. Quantitative blood flow measurements in the small animal cardiopulmonary system using digital subtraction angiography

    International Nuclear Information System (INIS)

    Purpose: The use of preclinical rodent models of disease continues to grow because these models help elucidate pathogenic mechanisms and provide robust test beds for drug development. Among the major anatomic and physiologic indicators of disease progression and genetic or drug modification of responses are measurements of blood vessel caliber and flow. Moreover, cardiopulmonary blood flow is a critical indicator of gas exchange. Current methods of measuring cardiopulmonary blood flow suffer from some or all of the following limitations--they produce relative values, are limited to global measurements, do not provide vasculature visualization, are not able to measure acute changes, are invasive, or require euthanasia. Methods: In this study, high-spatial and high-temporal resolution x-ray digital subtraction angiography (DSA) was used to obtain vasculature visualization, quantitative blood flow in absolute metrics (ml/min instead of arbitrary units or velocity), and relative blood volume dynamics from discrete regions of interest on a pixel-by-pixel basis (100x100 μm2). Results: A series of calibrations linked the DSA flow measurements to standard physiological measurement using thermodilution and Fick's method for cardiac output (CO), which in eight anesthetized Fischer-344 rats was found to be 37.0±5.1 ml/min. Phantom experiments were conducted to calibrate the radiographic density to vessel thickness, allowing a link of DSA cardiac output measurements to cardiopulmonary blood flow measurements in discrete regions of interest. The scaling factor linking relative DSA cardiac output measurements to the Fick's absolute measurements was found to be 18.90xCODSA=COFick. Conclusions: This calibrated DSA approach allows repeated simultaneous visualization of vasculature and measurement of blood flow dynamics on a regional level in the living rat.

    Few disasters can inspire more compassion for victims and families than those involving structural collapse. Video clips of children's bodies pulled from earthquake stricken cities and bombing sties tend to invoke tremendous grief and sorrow because of the totally unpredictable nature of the crisis and lack of even the slightest degree of negligence (such as with those who choose to ignore storm warnings). Heartbreaking stories of people buried alive for days provide a visceral and horrific perspective of some of greatest fears ever to be imagined by human beings. Current trends toward urban sprawl and increasing human discord dictates that structural collapse disasters will continue to present themselves at an alarming rate. The proliferation of domestic terrorism, HAZMAT and biological contaminants further complicates the matter further and presents a daunting problem set for Urban Search and Rescue (USAR) organizations around the world. This paper amplifies the case for robot assisted search and rescue that was first presented during the KNOBSAR project initiated at the Colorado School of Mines in 1995. It anticipates increasing technical development in mobile robot technologies and promotes their use for a wide variety of humanitarian assistance missions. Focus is placed on development of advanced robotic systems that are employed in a complementary tool-like fashion as opposed to traditional robotic approaches that portend to replace humans in hazardous tasks. Operational challenges for USAR are presented first, followed by a brief history of mobiles robot development. The paper then presents conformal robotics as a new design paradigm with emphasis on variable geometry and volumes. A section on robot perception follows with an initial attempt to characterize sensing in a volumetric manner. Collaborative rescue is then briefly discussed with an emphasis on marsupial operations and linked mobility. The paper concludes with an emphasis on Human Robot Interface

    Enterovirus 71 (EV71) is a major pathogen for severe hand, foot, and mouth disease (HFMD), which leads to severe neurological complications and has high morbidity and mortality. Reliable biomarker for the prediction of deterioration in EV71-infected children with central nervous system (CNS) involvement may reduce the cardiopulmonary failure and mortality. Here, we found that serum IL-27 levels were significantly higher in stage III EV71-infected HFMD patients with early cardiopulmonary failure and strong correlation with CRP levels. IL27p28 polymorphisms (rs153109, rs17855750, and rs181206) did not influence IL-27 production, and these three SNPs were not associated with EV71 infection risk and clinical stage. IL-27 can be used as an prediction indicator for early cardiopulmonary failure in EV71-infected children with CNS involvement. PMID:27403033

    From March 1994 to April 1997, 433 patients had undergone coronary artery bypass grafting without cardiopulmonary bypass in our institute. Sixty-eight patients had various organ dysfunctions and/or aortic atheroma or calcification and were regarded as high risk for cardiopulmonary bypass. In 277 patients surgery was performed through midline sternotomy, while in 156 minithoracotomy approach was used. In 361 patients single coronary artery bypass grafting was done, and in 72 two-coronary arteries were bypassed. In 63 patients who had graftable vessels in anterior wall and diffusely diseased ungraftable vessels in posterolateral and/or inferior wall, transmyocardial laser revascularisation was also done along with coronary artery bypass grafting to achieve complete myocardial revascularisation. Nine patients in this series were also subjected to simultaneous carotid endarterectomy along with myocardial revascularisation. In two patients complementary percutaneous transluminal coronary angioplasty of left circumflex coronary artery was done five days after minithoracotomy and left internal mammary artery to left anterior descending coronary artery bypass grafting. Forty-two cases were extubated in operating room. Average blood loss was 260 ml. Six patients were reexplored for postoperative bleeding. Seven patients had perioperative myocardial infarction. One developed neurological complication. Hospital mortality was 2.3 percent (10/433 cases) and four deaths were due to malignant ventricular arrhythmias. Nine patients developed chest wound complications. Average hospital stay after operation was six days, 423 patients were discharged from hospital and all of them were asymptomatic. During three years follow-up (range 3 to 38 months) there were three known cardiac deaths. Ninety percent (391) patients reported to the follow-up clinic and 91 percent of them were angina-free.

    2012-02-03

    The incidence of electrical failure during cardiopulmonary bypass (CPB) has been reported to occur in approximately 1 per 1000 cases. While the resultant morbidity and mortality is low, electrical failure is a life-threatening scenario. We report three major electrical failures during CPB in a patient population of 3500 over a 15-year period. These cases involved mains failure and generator shut down, mains failure and generator power surge, and failure of the uninterruptable power supply (UPS), which caused protected sockets to shut down. Protocols for preventative maintenance, necessary equipment, battery backup and guidelines for the successful management of such accidents during CPB are discussed.

    Full Text Available The perioperative management of patients with mediastinal mass is challenging. Complete airway obstruction and cardiovascular collapse may occur during the induction of general anaesthesia, tracheal intubation, and positive pressure ventilation. The intubation of trachea may be difficult or even impossible due to the compressed, tortuous trachea. Positive pressure ventilation may increase pre-existing superior vena cava (SVC obstruction, reducing venous return from the SVC causing cardiovascular collapse and acute cerebral oedema. We are describing here the successful management of a patient with a large anterior mediastinal mass by anaesthetizing the patient through a femoro-femoral cardiopulmonary bypass (fem-fem CPB.

    Heat exchanger leak on cardiopulmonary bypass is very rare, but serious. The exact incidence is not known. It is an emergency associated with the potential risk of blood contamination, air embolism and haemolysis, difficulty with re-warming, acidosis, subsequent septic shock, multi-organ failure and death. We present a prompt, highly co-ordinated algorithm for the successful management of this important rare complication. There is need for further research to look for safety devices that detect leaks and techniques to reduce bacterial load. It is essential that teams practice oxygenator change-out routines and have a well-established change-out protocol. PMID:25870370

    The location of rescue centers is a key problem in optimal resource allocation and logistics in emergency response.We propose a mathematical model for rescue center location with the considerations of emergency occurrence probability,catastrophe diffusion function and rescue function.Because the catastrophe diffusion and rescue functions are both nonlinear and time-variable,it cannot be solved by common mathematical programming methods.We develop a heuristic embedded genetic algorithm for the special model solution.The computation based on a large number of examples with practical data has shown us satisfactory results.

    2016-01-01

    The aim of this study was to investigate the correlation between basic life support skills in dentists who had completed the American Heart Association's Basic Life Support (BLS) Healthcare Provider qualification and time since course completion. Thirty-six dentists who had completed the 2005 BLS Healthcare Provider course participated in the study. We asked participants to perform 2 cycles of cardiopulmonary resuscitation on a mannequin and evaluated basic life support skills. Dentists who had previously completed the BLS Healthcare Provider course displayed both prolonged reaction times, and the quality of their basic life support skills deteriorated rapidly. There were no correlations between basic life support skills and time since course completion. Our results suggest that basic life support skills deteriorate rapidly for dentists who have completed the BLS Healthcare Provider. Newer guidelines stressing chest compressions over ventilation may help improve performance over time, allowing better cardiopulmonary resuscitation in dental office emergencies. Moreover, it may be effective to provide a more specialized version of the life support course to train the dentists, stressing issues that may be more likely to occur in the dental office.

    Showstack, Randy

    New York City, Sept. 17—The posters of missing loved ones are pasted onto New York City walls and street signs six days after 2 hijacked commercial airlines destroyed the World Trade Center in lower Manhattan on September 11. Several miles uptown from “ground zero,” heightened security hovers around the city's Office of Emergency Management rescue and relief command center, an around-the-clock operation. Police, firefighters, military, officials with the Federal Emergency Management Agency, communications technicians, and a beehive of others work in controlled chaos in this cavernous, convention center-sized hall, lined with computers and adorned with several American flags.After the original command center at 7 World Trade Center collapsed to rubble as an after-effect of the plane strikes, city officials scrambled to recreate it. Alan Leidner, director of New York's citywide geographic information systems (GIS), and who is with the Department of Information Technology and Telecommunications, knew that maps would be an integral component of the rescue and relief efforts. Maps provide emergency workers and others with accurate and detailed scientific data in the form of visual aids upon which they can make informed decisions.

  11. VEGETATIVE RESCUE AND CUTTINGS PROPAGATION OF Araucaria angustifolia (Bertol. Kuntze

    2015-02-01

    Full Text Available Brazilian pine or araucaria (Araucaria angustifolia is a coniferous tree with great economic, social and environmental importance in southern Brazil, being exploited for both wood production and for its edible pine nuts. However, no efficient cloning techniques are available and, therefore, the purpose of this study was to evaluate the effectiveness of vegetative rescue methods for cuttings propagation of the species. Shoots/cuttings were generated in two ways: 26 years old trees underwent coppicing and 20 years old trees had the primary branches on the upper third of crown pruned at 2, 20 and 50 cm from the main trunk. Orthotropic shoots were rooted after application of indole-3-butyric acid (IBA at 0, 2, 4 and 6 g.L-1. Coppicing produced 47 cuttings per plant with 90% orthotropic shoots, while pruning resulted in 182 cuttings per plant with 44% orthotropic shoots. Rooting success indexes were low with no influence of IBA, although they are slightly superior to the ones available in the literature for the species, ranging from 12 to 30% for the coppice shoots and from 0 to 28% for the branches shoots. We conclude that both vegetative rescue techniques are viable and have potentially important applications. Coppicing is recommended for the propagation aiming the production of wood, while shoots derived from the side branches of the crown are more appropriate for seeds orchards formation.

    The potential benefits of distributed robotics systems in applications requiring situational awareness, such as search-and-rescue in emergency situations, are indisputable. The efficiency of such systems requires robotic agents capable of coping with uncertain and dynamic environmental conditions. For example, after an earthquake, a tremendous effort is spent for days to reach to surviving victims where robotic swarms or other distributed robotic systems might play a great role in achieving this faster. However, current technology falls short of offering centimeter scale mobile agents that can function effectively under such conditions. Insects, the inspiration of many robotic swarms, exhibit an unmatched ability to navigate through such environments while successfully maintaining control and stability. We have benefitted from recent developments in neural engineering and neuromuscular stimulation research to fuse the locomotory advantages of insects with the latest developments in wireless networking technologies to enable biobotic insect agents to function as search-and-rescue agents. Our research efforts towards this goal include development of biobot electronic backpack technologies, establishment of biobot tracking testbeds to evaluate locomotion control efficiency, investigation of biobotic control strategies with Gromphadorhina portentosa cockroaches and Manduca sexta moths, establishment of a localization and communication infrastructure, modeling and controlling collective motion by learning deterministic and stochastic motion models, topological motion modeling based on these models, and the development of a swarm robotic platform to be used as a testbed for our algorithms.

    Concerning the surrounding flora, the implementation of pipelines may cause fragmentation and isolation of the remaining natural vegetation, possibly changing the forest structure; thus raising the border effect; modifying the ratio of species and life forms, decreasing the vegetal diversity and/or causing a lack of connectivity among the remaining indigenous forest resources. In the case of pipelines, the most important environmental measure intended to mitigate the damage caused to the flora is the adoption of Indigenous Flora Rescue Programs. This paper is aimed at analyzing the programs currently applied during the implementation of the GASENE project, by conducting a case study. The main targets of such program are obtaining seeds and fruits with a view to subsidize the potential production of sapling to be further employed in the recovery of areas impacted by the pipeline works; and then relocate the most significant samples of species rescued from the suppressed areas in order to comprise forest areas adjacent to the pipeline's right-of-way. The programs had little differences in their methodology while being implemented, however, we consider that up to the present moment the results obtained in the preservation of species of native flora have been satisfactory.

  15. Influencing factors of embryo rescue in seedless grape

    International Nuclear Information System (INIS)

    In this study, we investigated the impact of inoculating stage, medium type and concentration of plant growth regulators on embryo rescue effectiveness by L25(5)6 orthogonal design using selfed ovules of Venus Seedless as the testing material. The main results were as follows. The most important factor influencing ovule germination was inoculating stage. Ovule germinating rate gradually increased as inoculating being postponed. The highest germinating rate appeared when inoculation was done 55d after flowering. Other influencing factors were IBA concentration, exogenous amino acid, 6-BA concentration, GA3 concentration and medium type in descending order. The best embryo rescue result was based on Nitsch medium including 1.0 mg/L IBA, 0.1 mg/L GA3, 0.7 mg /L 6-BA and 2.0 mmol/L glutamine using ovules inoculated 55d after flowering. The highest germinating rate reached 41.25%, and a batch of seedlings was also obtained. (author)

    2016-04-01

    Remotely Piloted Aircraft Systems (RPAS) also known as Unmanned Aerial Systems (UAS) are nowadays becoming more and more popular in several applications. Even though a complete regulation is not yet available all over the world, researches, tests and some real case applications are wide spreading. These technologies can bring many benefits also to the mountain operations especially in emergencies and harsh environmental conditions, such as Search and Rescue (SAR) and avalanche rescue missions. In fact, during last decade, the number of people practicing winter sports in backcountry environment is increased and one of the greatest hazards for recreationists and professionals are avalanches. Often these accidents have severe consequences leading, mostly, to asphyxia-related death, which is confirmed by the hard drop of survival probability after ten minutes from the burying. Therefore, it is essential to minimize the time of burial. Modern avalanche beacon (ARTVA) interface guides the rescuer during the search phase reducing its time. Even if modern avalanche beacons are valid and reliable, the seeking range influences the rescue time. Furthermore, the environment and morphologic conditions of avalanches usually complicates the rescues. The recursive methodology of this kind of searching offers the opportunity to use automatic device like drones (RPAS). These systems allow performing all the required tasks autonomously, with high accuracy and without exposing the rescuers to additional risks due to secondary avalanches. The availability of highly integrated electronics and subsystems specifically meant for the applications, better batteries, miniaturized payload and, in general, affordable prices, has led to the availability of small RPAS with very good performances that can give interesting application opportunities in unconventional environments. The present work is one of the outcome from the experience made by the authors in RPAS fields and in Mechatronics

    Based on the complete genome sequence of Newcastle disease virus (NDV) ZJI strain,seven pairs of primers were designed to amplify a cDNA fragment for constructing the plasmid pNDV/ZJI,which contained the full-length cDNA of the NDV ZJI strain.The pNDV/ZJI,with three helper plasmids,pCIneoNP,pCIneoP and pCIneoL,were then cotransfected into BSR-T7/5 cells expressing T7 RNA polymerase.After inoculation of the transfected cell culture supernatant into embryonated chicken eggs from specific-pathogen-free (SPF) flock,an infectious NDV ZJI strain was successfully rescued.Green fluorescent protein (GFP) gene was amplified and inserted into the NDV full-length cDNA to generate a GFP-tagged recombinant plasmid pNDV/ZJIGFP.After cotransfection of the resultant plasmid and the three support plasmids into BSR-T7/5 cells,the recombinant NDV,NDV/ZJIGFP,was rescued.Specific green fluorescence was observed in BSR-T7/5 and chicken embryo fibroblast (CEF) cells 48h post-infection,indicating that the GFP gene was expressed at a relatively high level.NDV/ZJIGFP was inoculated into 10-day-old SPF chickens by oculonasal route.Four days post-infection,strong green fluorescence could be detected in the kidneys and tracheae,indicating that the recombinant GFP-tagged NDV could be a very useful tool for analysis of NDV dissemination and pathogenesis.

    See Duran-Aniotz et al. (doi:10.1093/brain/awv401) for a scientific commentary on this article.The aberrant accumulation of toxic protein aggregates is a key feature of many neurodegenerative diseases, including Huntington's disease, amyotrophic lateral sclerosis and Alzheimer's disease. As such, improving normal proteostatic mechanisms is an active target for biomedical research. Although they share common pathological features, protein aggregates form in different subcellular locations. Nε-lysine acetylation in the lumen of the endoplasmic reticulum has recently emerged as a new mechanism to regulate the induction of autophagy. The endoplasmic reticulum acetylation machinery includes AT-1/SLC33A1, a membrane transporter that translocates acetyl-CoA from the cytosol into the endoplasmic reticulum lumen, and ATase1 and ATase2, two acetyltransferases that acetylate endoplasmic reticulum cargo proteins. Here, we used a mutant form of α-synuclein to show that inhibition of the endoplasmic reticulum acetylation machinery specifically improves autophagy-mediated disposal of toxic protein aggregates that form within the secretory pathway, but not those that form in the cytosol. Consequently, haploinsufficiency of AT-1/SLC33A1 in the mouse rescued Alzheimer's disease, but not Huntington's disease or amyotrophic lateral sclerosis. In fact, intracellular toxic protein aggregates in Alzheimer's disease form within the secretory pathway while in Huntington's disease and amyotrophic lateral sclerosis they form in different cellular compartments. Furthermore, biochemical inhibition of ATase1 and ATase2 was also able to rescue the Alzheimer's disease phenotype in a mouse model of the disease. Specifically, we observed reduced levels of soluble amyloid-β aggregates, reduced amyloid-β pathology, reduced phosphorylation of tau, improved synaptic plasticity, and increased lifespan of the animals. In conclusion, our results indicate that Nε-lysine acetylation in the endoplasmic

    Full Text Available Abstract OBJECTIVE To identify, in the perception of nurses, the factors that affect the quality of cardiopulmonary resuscitation (CPR in adult inpatient units, and investigate the influence of both work shifts and professional experience length of time in the perception of these factors. METHOD A descriptive, exploratory study conducted at a hospital specialized in cardiology and pneumology with the application of a questionnaire to 49 nurses working in inpatient units. RESULTS The majority of nurses reported that the high number of professionals in the scenario (75.5%, the lack of harmony (77.6% or stress of any member of staff (67.3%, lack of material and/or equipment failure (57.1%, lack of familiarity with the emergency trolleys (98.0% and presence of family members at the beginning of the cardiopulmonary arrest assistance (57.1% are factors that adversely affect the quality of care provided during CPR. Professional experience length of time and the shift of nurses did not influence the perception of these factors. CONCLUSION The identification of factors that affect the quality of CPR in the perception of nurses serves as parameter to implement improvements and training of the staff working in inpatient units.

  20. Use of the cardiopulmonary flow index to evaluate cardiac function in thoroughbred horses

    International Nuclear Information System (INIS)

    The ratio of the cardiopulmonary blood volume to stroke volume is called the cardiopulmonary flow index (CPFI). The CPFI can be determined indirectly from the simultaneous recording of a radiocardiogram and an electrocardiogram. The CPFI and cardiac output were measured simultaneously in horses that were diagnosed as having cardiac disease. The results obtained from these subjects were compared with those from control animals and significant differences were found between the mean CPFI of the control horses and those with macroscopically visible myocardial fibrosis on post mortem examination. No significant differences were found between the means of the cardiac output measured in either of the groups of horses. The effect of pharmacological acceleration of the heart rate on the CPFI was also studied. Significant differences were found between the mean CPFI and the slopes of the regression lines of CPFI on heart rate of the control and principal groups of horses. These differences were greatest at heart rates near to the resting heart rates of the individuals. The CPFI was found to be a more sensitive measure of cardiac function than cardiac output, in the horses. 16 refs., 2 figs., 2 tabs

  1. Nontraumatic postmortem computed tomographic demonstration of cerebral gas embolism following cardiopulmonary resuscitation

    International Nuclear Information System (INIS)

    The aim of this study was to investigate cerebral gas embolism (GE) on nontraumatic postmortem CT (PMCT), regarding its frequency, location (arterial or venous), and causes. Our subjects were 404 nontraumatically deceased patients who had been in a state of cardiopulmonary arrest on arrival at our emergency room. PMCT was performed within 2 h of the confirmation of death. Cardiopulmonary resuscitation (CPR) was performed on 387 of the 404 subjects; and of these, cerebral GE was detected in 29 (7.5%) subjects (3 arterial, 25 venous, 1 undeterminable). Cerebral GE was not noted in the other 17 of the 404 subjects who did not undergo CPR. However, there was no significant difference in the incidence of cerebral GE between the subjects who underwent CPR and those who did not. The mechanism of cerebral arterial GE was presumed due to pulmonary barotrauma and/or paradoxical embolism, while the thoracic pump theory was suggested to explain the cerebral venous GE. Cerebral arterial/venous GE is found in CPR cases on nontraumatic PMCT. (author)

    Recognizing and responding to a cardiac arrest in the hospital setting is a high stress, high anxiety event for all healthcare providers. It requires the performance of several basic, but extremely important cardiopulmonary resuscitation (CPR) skills and response priorities. If not executed correctly and in a timely manner, a bad outcome may result. Poor retention of cardiopulmonary resuscitation skills and priorities is well documented in the literature. An integrative review of the evidence was conducted to answer the question, "Is there a more effective training method to improve nurses' retention of CPR priorities during an in hospital cardiac arrest as compared to traditional American Heart Association training? "This review evaluated high fidelity and low fidelity simulation training, online or computer-based training and video instruction as potential teaching strategies focusing on CPR priorities. The role of deliberate practice is discussed. The strongest evidence suggests that a teaching plan employing brief, frequent, repetitive or deliberate practice used in collaboration with low fidelity or high fidelity simulation may be a potential strategy to improve nurses' retention of CPR priorities over time.

    Full Text Available Cold agglutinins are of unique relevance in cardiac surgerybecause of the use of hypothermic cardiopulmonary bypass (CPB. Cold autoimmune diseases are defined by the presence of abnormal circulating proteins (usually IgM or IgA antibodies that agglutinate in response to a decrease in body temperature. These disorders include cryoglobulinemia and cold hemagglutinin disease.Immunoglobulin M autoantibodies to red blood cells, which activateat varying levels of hypothermia, can cause catastrophic hemagglutination,microvascular thrombosis, or hemolysis. Management of anesthesia in these patients includes strict maintenance of normothermia. Patients scheduled for the surgery requiring cardiopulmonary bypass present significant challenges. Use of systemic hypothermia may be contraindicated, and cold cardioplegia solutions may precipitate intracoronary hemagglutination with consequent thrombosis, ischemia, or infarction. Management of CPB andmyocardial protection requires individualized planning. We describea case of MV repair and CABG in a patient with high titercold agglutinins and high thermal amplitude for antibody activation.Normothermic CPB and continuous warm blood cardioplegia weresuccessfully used.

    Full Text Available The mechanisms underlying the action of Indian red scorpion Buthus tamulus (BT venom-induced augmentation of cardiopulmonary reflexes elicited by intravenous injection of 5-HT were examined in urethane anaesthetized rats. The 5-HT produced a concentration-dependent increase in time-response area of bradycardiac response, with the responses at submaximal concentrations shifted to the left after exposure to BT venom (20 µg/kg, IV. Aprotinin (6000 kallikrein inactivating unit, IV as such had no effect on 5-HT reflex responses (bradycardia, hypotension, and apnea, but blocked the venom-induced reflex augmentation. While ondansetron (10 µg/kg, IV completely blocked the 5-HT reflex responses, these reappeared partially after venom exposure (20 µg/kg. Exposure to bradykinin (50 µg/kg, IV for 30 min also augmented the 5-HT-induced reflex responses similar to venom. The bradykinin-induced augmentation was also blocked by ondansetron. Results indicate that the venom-induced augmentation of cardiopulmonary reflexes is mediated through kinins sensitizing 5-HT3 receptor subtypes.

    Purpose of review Survival rates from cardiac arrest are unacceptably low. The present review aims to summarize recent contributions to cardiopulmonary resuscitation research in relation to hemodynamic consequences and especially survival resulting from interruption of chest compressions for defibrillation and rescue breathing. Recent findings Data from animal and human studies strongly support the negative consequences for overall survival when cardiopulmonary resuscitation is interrupted for rescue breathing and rhythm analysis. Furthermore, in settings of prolonged cardiac arrest electrical defibrillation may not have the highest priority as initial intervention. Summary Interruption of cardiopulmonary resuscitation negatively affects survival from cardiac arrest and more time dependent interventions are necessary.

    Background There is no research,either at home or abroad,focusing on assessing the cardiopulmonary functional reserve and exercise tolerance in patients with pulmonary embolism (PE),but the benefits of early exercise are well recognized.The goals of this study were to assess cardiopulmonary functional reserve in treated PE patients using the inert gas rebreathing method of the cardiopulmonary exercise test (CPET),and to compare it with traditional methods.Methods CPET on the bicycle ergometer were performed in 40 patients with age,gender,body mass index,systolic blood pressure,and pulmonary function matched.The first group was the PE group composed of 16 PE patients (5 male,11 female) who were given the standard antithrombotic therapy for two weeks.The second group was composed of 24 normal individuals (10 male,14 female).Both groups were evaluated by cardiac ultrasound examination,6-minute walking test (6MVVT),and CPET.Results (1) Right ventricular systolic pressure (RVSP) in the PE group increased significantly compared to the control group,(34.81±8.15) mmHg to (19.75±3.47) mmHg (P <0.01).But neither right atrial end-systolic diameter (RASD) nor right ventricular end-diastolic diameter (RVDD) in the PE patients had changed when compared with the controls.The 6-minute walk distance was significantly reduced in the PE patients compared with normal subjects,(447.81±79.20) m vs.(513.75±31.45) m (P <0.01).Both anaerobic threshold oxygen consumption (VO2AT) and peak oxygen consumption (VO2peak) were significantly lower in patients with PE,while CO2 equivalent ventilation (VE/VCO2 slope) was higher;VO2AT (9.44±3.82) ml·kg1.min-1 vs.(14.62±2.93) ml.kg-1.min-1 (P <0.01) and VO2peak (12.26±4.06) ml.kg-1.min-1 vs.(23.46±6.15) ml.kg-1.min-1 (P <0.01) and VE/VCO2 slope 35.47±6.66 vs.26.94±3.16 (P <0.01).There was no significant difference in resting cardiac output (CO) between the PE and normal groups,whereas peak cardiac output (peak CO)and the

    Full Text Available Daily pollution data (collected in Graz over 16 years and in the Linz over 18 years were used for time series studies (GAM and case-crossover on the relationship with daily mortality (overall and specific causes of death. Diagnoses of patients who had been transported to hospitals in Linz were also available on a daily basis from eight years for time series analyses of cardiopulmonary emergencies. Increases in air pollutant levels over several days were followed by increases in mortality and the observed effects increased with the length of the exposure window considered, up to a maximum of 15 days. These mortality changes in Graz and Linz showed similar patterns like the ones found before in Vienna. A significant association of mortality could be demonstrated with NO2, PM2.5 and PM10 even in summer, when concentrations are lower and mainly related to motor traffic. Cardiorespiratory ambulance transports increased with NO2/PM2.5/PM10 by 2.0/6.1/1.7% per 10 µg/m³ on the same day. Monitoring of NO2 (related to motor traffic and fine particulates at urban background stations predicts acute effects on cardiopulmonary emergencies and extended effects on cardiopulmonary mortality. Both components of urban air pollution are indicators of acute cardiopulmonary health risks, which need to be monitored and reduced, even below current standards.

    Introduction: Standards have a significant role in showing the minimum level of optimal optimum and the expected performance. Since the perfusion technology staffs play an the leading role in providing the quality services to the patients undergoing open heart surgery with cardiopulmonary bypass machine, this study aimed to assess the standards on how Iranian perfusion technology staffs evaluate and manage the patients during the cardiopulmonary bypass process and compare their practice with the recommended standards by American Society of Extracorporeal Technology. Methods: In this descriptive study, data was collected from 48 Iranian public hospitals and educational health centers through a researcher-created questionnaire. The data collection questionnaire assessed the standards which are recommended by American Society of Extracorporeal Technology. Results: Findings showed that appropriate measurements were carried out by the perfusion technology staffs to prevent the hemodilution and avoid the blood transfusion and unnecessary blood products, determine the initial dose of heparin based on one of the proposed methods, monitor the anticoagulants based on ACT measurement, and determine the additional doses of heparin during the cardiopulmonary bypass based on ACT or protamine titration. It was done only in 4.2% of hospitals and health centers. Conclusion: Current practices of cardiopulmonary perfusion technology in Iran are inappropriate based on the standards of American Society of Cardiovascular Perfusion. This represents the necessity of authorities’ attention to the validation programs and development of the caring standards on one hand and continuous assessment of using these standards on the other hand.

    Multiple interventions have been tested in models of cardiopulmonary resuscitation (CPR) to optimize drug use, chest compressions, and ventilation. None has studied the effects of positive end-expiratory pressure (PEEP) on outcome. We hypothesized that because PEEP can reverse pulmonary atelectasis, lower pulmonary vascular resistance, and potentially improve cardiac output, its use during CPR would increase survival.

    Treguear, T; Peters, L

    1995-01-01

    In San Jose, Costa Rica, the nongovernmental organization PROCAL has established two rescue homes for sexually abused girls 10-15 years of age. One of these homes is devoted to the care of pregnant girls. In almost all cases, the perpetrator was a male relative. Since girls are taught they must obey older male relatives, they are powerless to stop the abuse. When girls become pregnant as a result of sexual abuse, they face social ostracism and are blamed for their participation in sexual activity. PROCAL counsels the girls that they are victims of their own lack of power and provides them with skills and education they need to return to society and start a new life. The stories of two young girls who became pregnant as a result of sexual abuse and were helped by PROCAL are presented. PMID:12319363

    CUI Yi-an; CAI Zi-xing; WANG Lu

    2008-01-01

    A new scene recognition system was presented based on fuzzy logic and hidden Markov model(HMM) that can be applied in mine rescue robot localization during emergencies. The system uses monocular camera to acquire omni-directional images of the mine environment where the robot locates. By adopting center-surround difference method, the salient local image regions are extracted from the images as natural landmarks. These landmarks are organized by using HMM to represent the scene where the robot is, and fuzzy logic strategy is used to match the scene and landmark. By this way, the localization problem, which is the scene recognition problem in the system, can be converted into the evaluation problem of HMM. The contributions of these skills make the system have the ability to deal with changes in scale, 2D rotation and viewpoint. The results of experiments also prove that the system has higher ratio of recognition and localization in both static and dynamic mine environments.

    2014-05-01

    Full Text Available In this paper Akpareva Aruoriwo aims to evaluate the adequacy of the framework available for the financing of corporate rescues in the UK. She examines the legal provision made for prioritising creditors who get involved after an insolvency has been declared, with reference to examples from America and Canada. Without post-insolvency funding, companies may find it very difficult to survive, and without protection for post-insolvency creditors, those creditors may not wish to provide this sort of funding. The author examines the arguments for and against this kind of creditor protection, looking at past calls for reforms to the law and the preparedness of the UK to adopt any reforms.

  2. Microbes Promote Amino Acid Harvest to Rescue Undernutrition in Drosophila

    2015-02-01

    Full Text Available Microbes play an important role in the pathogenesis of nutritional disorders such as protein-specific malnutrition. However, the precise contribution of microbes to host energy balance during undernutrition is unclear. Here, we show that Issatchenkia orientalis, a fungal microbe isolated from field-caught Drosophila melanogaster, promotes amino acid harvest to rescue the lifespan of undernourished flies. Using radioisotope-labeled dietary components (amino acids, nucleotides, and sucrose to quantify nutrient transfer from food to microbe to fly, we demonstrate that I. orientalis extracts amino acids directly from nutrient-poor diets and increases protein flux to the fly. This microbial association restores body mass, protein, glycerol, and ATP levels and phenocopies the metabolic profile of adequately fed flies. Our study uncovers amino acid harvest as a fundamental mechanism linking microbial and host metabolism, and highlights Drosophila as a platform for quantitative studies of host-microbe relationships.

  4. Multi-robot Task Allocation for Search and Rescue Missions

    International Nuclear Information System (INIS)

    Many researchers from academia and industry are attracted to investigate how to design and develop robust versatile multi-robot systems by solving a number of challenging and complex problems such as task allocation, group formation, self-organization and much more. In this study, the problem of multi-robot task allocation (MRTA) is tackled. MRTA is the problem of optimally allocating a set of tasks to a group of robots to optimize the overall system performance while being subjected to a set of constraints. A generic market-based approach is proposed in this paper to solve this problem. The efficacy of the proposed approach is quantitatively evaluated through simulation and real experimentation using heterogeneous Khepera-III mobile robots. The results from both simulation and experimentation indicate the high performance of the proposed algorithms and their applicability in search and rescue missions

    Full Text Available Objective: Homologous blood transfusion after open heart surgery puts a tremendous load on the blood banks. This prospective randomized study evaluates the efficacy of infusing back residual cardiopulmonary bypass (CPB circuit i.e., pump blood as a means to reduce homologous transfusion after coronary artery bypass surgery (CABG and whether its use increases postoperative drainage. Materials and Methods: Sixty-seven consecutive patients who underwent elective CABGs under CPB were randomized into 2 groups: (1 cases where residual pump blood was used and (2 controls where residual pump blood was not used. Patients were monitored for hourly drainage on the day of surgery and the 1 st postoperative day and the requirements of homologous blood and its products. Data were matched regarding change in Hemoglobin, Packed Cell Volume and coagulation parameters till 1st postoperative day. All cases were followed up for three years. Results: There was a marginal reduction in bleeding pattern in the early postoperative period in the cases compared to controls. The requirement of homologous blood and its products were also reduced in the cases. Conclusions: The use of CPB circuit blood is safe in the immediate postoperative period. The requirement of homologous blood transfusion can come down if strict transfusion criteria are maintained.

    2010-07-01

    Mine rescue training procedures related to dangerous gases in mines were discussed. Methods of detecting carbon dioxide (CO{sub 2}) in abandoned opening and old adits were presented. High concentrations of CO{sub 2} combine with hemoglobin and lead to a lack of oxygen supply to the inner organs. Nitric acid forms in the alveoli and can lead to injuries or death after a period of 4 to 12 hours. Exposure to very high concentrations of CO{sub 2} can cause people to immediately lose consciousness. CO{sub 2} concentrations in the blood can change pH blood values. Members of mine rescue teams should be equipped with breathing equipment and be between 18 and 40 years old. Training rescue operations should be conducted 4 times per year. While larger mines have their own rescue teams, smaller mines must ensure that guest rescue teams are familiar with their mines. Various mine training activities were reviewed. 5 refs.

    The aim of this work was to analyze whether there are differences between the development pattern of Antillean manatee (Trichechus manatus) calves born in captivity and those rescued and kept under rehabilitation. Biometrics data were collected from 1990 to 2010 from 38 calves, 29 of which still had the remnants of the umbilical cord and had been rescued from the Brazilian northeastern coastline (Group I), and nine individuals that were born in captivity and remained with their mothers (Group II). Among the measures obtained through biometry, the total length and weight of the animal were recorded. Given that the breastfeeding of calves occurs approximately until the age of 2 yr, data obtained until the 24th month of life of each individual were evaluated. An average increase in weight of 53.50 +/- 38.54 kg (mean +/- standard deviation [SD]) was detected in Group I and a gain of 106.87 +/- 47.21 kg (mean +/- SD) in Group II. From months 13 to 24, no significant difference in the weight increment was observed. A similar pattern occurred with regard to the increase in the overall length during the first year, where animals from Group I grew 34.81 +/- 17.94 cm (mean +/- SD) and from Group II grew 83.83 +/- 28.21 cm, a statistically significant difference. The growth was not significantly different from 13 to 24 mo. The results found in this study identified the need for a review of the nutritional diet offered to orphaned calves rescued and kept in captivity. The results also support the need for a better adequacy of facilities for these animals as a way to encourage the management strategies adopted for manatee calves maintained in captivity.

    A 17-year-old girl with drepanocytic (sickle-cell) anemia who was being treated with hydroxyurea and periodic blood transfusions through a Hickman-type catheter was admitted for periodic episodes of fever. Blood cultures were positive for methicillin-sensitive Staphylococcus aureus. Massive right atrial thrombosis with pulmonary embolism and bacterial endocarditis were detected by computed tomography. Surgery with a beating heart and cardiopulmonary bypass was undertaken. Drepanocytic anemia in individuals homozygous for hemoglobin S is a rare condition in Spain but we are beginning to see a few cases, in which management during anesthesia will be more complicated. High-risk surgery can be carried out in these patients without adverse events if the anesthesiologist is guided by a complete blood workup and takes precautions during and after surgery to control hydration, oxygenation, temperature, and the acid-base balance.

    2008-07-01

    Errors in blood flow delivery due to shunting have been reported to reduce flow by, potentially, up to 40-83% during cardiopulmonary bypass. The standard roller-pump measures revolutions per minute and a calibration factor for different tubing sizes calculates and displays flow accordingly. We compared displayed roller-pump flow with ultrasonically measured flow to ascertain if measured flow correlated with the heart-lung pump flow reading. Comparison of flows was measured under varying conditions of pump run duration, temperature, viscosity, varying arterial\\/venous loops, occlusiveness, outlet pressure, use of silicone or polyvinyl chloride (PVC) in the roller race, different tubing diameters, and use of a venous vacuum-drainage device.

    Full Text Available The lung tumors with carinal involvement are frequently managed with tracheal sleeve pneumonectomy and tracheobronchial anastomosis without use of cardiopulmonary bypass (CPB. Various modes of ventilation have been described during tracheal resection and anastomosis. Use of CPB during this period allows the procedure to be conducted in a more controlled way. We performed tracheal sleeve pneumonectomy for adenoid cystic carcinoma of left lung involving carina. The surgery was performed in two stages. In the first stage, left pneumonectomy was performed and in the second stage after 48 h, tracheobronchial resection and anastomosis was performed under CPB. Second stage was delayed to avoid excessive bleeding (due to heparinization from the extensive vascular raw area left after pneumonectomy. Meticulous peri-operative planning and optimal post-operative care helped in successful management of a complex case, which is associated with high morbidity and mortality.

  14. The potential of the novel leukocyte removal filter in cardiopulmonary bypass.

    Science.gov (United States)

    Fujii, Yutaka

    2016-01-01

    Cardiopulmonary bypass (CPB) is indispensable for cardiac surgery but leads to systemic inflammatory responses and leukocyte activation, possibly due to blood contact with the surface of the CPB unit, surgical, ischemic reperfusion injury, etc. Systemic inflammatory responses during CPB result in increased morbidity and mortality. Activation of leukocytes is an important part of this process and directly contributes to coagulopathy and hemorrhage. This inflammatory response may contribute to the development of postoperative complications, including myocardial dysfunction, respiratory failure, renal and neurologic dysfunction, altered liver function and ultimately, multiple organ failure. Various pharmacologic and mechanical strategies have been developed to minimize the systemic inflammatory response during CPB. For example, leukocyte removal filters were developed in the 1990s for incorporation into the CPB circuit. However, studies of this approach have yielded conflicting findings. The purpose of this was to review the studies of a novel leukocyte removal filter in patients undergoing CPB. PMID:26613267

  15. Are the current guideline recommendations for neonatal cardiopulmonary resuscitation safe and effective?

    Science.gov (United States)

    Rottenberg, Eric M

    2016-08-01

    A recently published review of approaches to optimize chest compressions in the resuscitation of asphyxiated newborns discussed the current recommendations and explored potential determinants of effective neonatal cardiopulmonary resuscitation (CPR). However, not all potential determinants of effective neonatal CPR were explored. Chest compression shallower than the current guideline recommendation of approximately 33% of the anterior-posterior (AP) chest diameter may be safer and more effective. From a physiological standpoint, high-velocity brief duration shallower compression may be more effective than current recommendations. The application of a 1- or 2-finger method of high-impulse CPR, which would depend on the size of the subject, may be more effective than using a 2-thumb (TT) encircling hands method of CPR. Adrenaline should not be used in the treatment of asphyxiated neonates and when necessary titrated vasopressin should be used. PMID:27220864

  16. A Review of the Performance of Artifact Filtering Algorithms for Cardiopulmonary Resuscitation

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Various filtering strategies have been adopted and investigated to suppress the cardiopulmonary resuscitation (CPR artifact. In this article, two types of artifact removal methods are reviewed: one is the method that removes CPR artifact using only ECG signals, and the other is the method with additional reference signals, such as acceleration, compression depth and transthoracic impedance. After filtering, the signal-to-noise ratio is improved from 0 dB to greater than 2.8 dB, the sensitivity is increased to > 90% as recommended by the American Heart Association, whereas the specificity was far from the recommended 95%, which is considered to be the major drawback of the available artifact removal methods. The overall performance of the adaptive filtering methods with additional reference signal outperforms the methods using only ECG signals. Further research should focus on the refinement of artifact filtering methods and the improvement of shock advice algorithms with the presence of CPR.

    Full Text Available Abstract Cardiopulmonary nematodes of dogs and cats cause parasitic diseases of central relevance in current veterinary practice. In the recent past the distribution of canine and feline heartworms and lungworms has increased in various geographical areas, including Europe. This is true especially for the metastrongyloids Aelurostrongylus abstrusus, Angiostrongylus vasorum and Crenosoma vulpis, the filarioid Dirofilaria immitis and the trichuroid Eucoleus aerophilus (syn. Capillaria aerophila. The reasons of this emergence are little known but many drivers such as global warming, changes in vector epidemiology and movements in animal populations, may be taken into account. The purpose of this article is to review the knowledge of the most important heartworm and lungworm infections of dogs and cats in Europe. In particular recent advances in epidemiology, clinical and control are described and discussed.

    Full Text Available During cardiopulmonary bypass (CPB, neutrophils become activated due to contact with extracorporeal surfaces and binding of complement fragments C3a and C5a, leading to extravasation and subsequent tissue damage. In this study, the effects of the leumedin NPC 15669 (N [9H - (2,7 dimethylfluorenyl - 9 - methoxy car bonyl]-L-leucine, a leukocyte recruitment inhibitor, were evaluated in a pig model of CPB. NPC 15669 caused significant inhibition of CPB associated increase in CD18 upregulation, lung tissue myeloperoxidase content, and percentage wet weight compared to controls. Lung histology revealed clear airways and minimal neutrophil infiltration in treated animals vs. significant oedema and cellular infiltration in controls. It is concluded that CPB causes a dramatic increase in neutrophil CD18, and that leumedins are effective in inhibiting neutrophil activation and subsequent tissue injury when administered during CPB.

    Previous studies showed that decreased cerebral saturation during cardiac surgery is related to adverse postoperative outcome. Therefore, we investigated the influence of intraoperative events on cerebral tissue saturation in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). A total of 52 adult patients who underwent cardiac surgery using pulsatile CPB were included in this prospective explorative study. Cerebral tissue oxygen saturation (SctO2) was measured in both the left and right cerebral hemisphere. Intraoperative events, involving interventions performed by anesthesiologist, surgeon, and clinical perfusionist, were documented. Simultaneously, in-line hemodynamic parameters (partial oxygen pressure, partial carbon dioxide pressure, hematocrit, arterial blood pressure, and CPB flow rates) were recorded. Cerebral tissue saturation was affected by anesthetic induction (p partial oxygen pressures changed. Cerebral tissue oximetry effectively identifies changes related to surgical events or vulnerable periods during cardiac surgery. Future studies are needed to identify methods of mitigating periods of reduced cerebral saturation. PMID:26390677

    Several cardiovascular and pulmonary models have been proposed in the last few decades. However, very few have addressed the interactions between these two systems. Our group has developed an integrated cardiopulmonary model (CP Model) that mathematically describes the interactions between the cardiovascular and respiratory systems, along with their main short-term control mechanisms. The model has been compared with human and animal data taken from published literature. Due to the volume of the work, the paper is divided in two parts. The present paper is on model development and normophysiology, whereas the second is on the model's validation on hypoxic and hypercapnic conditions. The CP Model incorporates cardiovascular circulation, respiratory mechanics, tissue and alveolar gas exchange, as well as short-term neural control mechanisms acting on both the cardiovascular and the respiratory functions. The model is able to simulate physiological variables typically observed in adult humans under normal and pathological conditions and to explain the underlying mechanisms and dynamics. PMID:26683899

    The cardiopulmonary effects of capnoperitoneum were investigated in 8 spontaneously breathing, young adult female cats undergoing laparoscopic pancreatic biopsy (intra-abdominal pressure 12 mmHg). Cats were premedicated with acepromazine and hydromorphone, induced with ketamine and diazepam, and maintained using an end-tidal isoflurane concentration of 1.13% in 100% oxygen. Direct systemic arterial blood pressure, heart and respiratory rates, end-tidal carbon dioxide (CO(2)), and isoflurane were recorded every 5 min before insufflation (baseline), during insufflation of the abdomen with CO(2), and following desufflation. Arterial blood samples were drawn at baseline, at 10 and 30 min of insufflation, and 5 min after desufflation for blood gases. The significant findings (P cats despite no artificial maintenance of minute ventilation. PMID:22379196

    Effective cardiopulmonary resuscitation (CPR) skills are essential for better patient survival, but whether these skills are associated with knowledge of and self-efficacy in CPR is not well known. The purpose of this study was to assess the quality of CPR skills and identify the association of the psychomotor skills with knowledge and self-efficacy at the time of CPR skills training. A convenience sample of 124 nursing students participated in a one-group posttest-only study. The quality of CPR psychomotor skills, as assessed by structured observation using a manikin, was suboptimal. Nursing students who performed correct chest compression skills reported higher self-efficacy, but there was no association between CPR psychomotor skills and total knowledge. Rigorous skills training sessions with more objective feedback on performance and individual coaching are warranted to enable mastery learning and self-efficacy. PMID:24219782

    Full Text Available Background and objectives: The intense trauma response triggered by cardiopulmonary bypass can lead to increased morbidity and mortality. The present study evaluated whether clonidine, a drug of the class of α-2 agonists, administered by spinal route, without association with local anesthetics or opioids, reduces this response in cardiac surgery with cardiopulmonary bypass. Method: A total of 27 patients between 18 and 75 years old, divided by non-blinded fashion into a control group (15 and a clonidine group (12, were studied. All patients underwent identical technique of general anesthesia. Then, only the clonidine group received 1 μg kg−1 clonidine by spinal route. Levels of blood glucose, lactate and cortisol were measured at three consecutive times: T1, at the time of installation of invasive arterial pressure; T2, 10 min after the first dose for cardioplegia; and T3, at the time of skin suture; and troponin I values at T1 and T3. The variation of results between T2-T1, T3-T2, and T3-T1 was also evaluated. Results: There was a statistically significant difference only with respect to the variation in blood glucose in the clonidine group: T3-T2, p = 0.027 and T3-T1, p = 0.047. Conclusions: Spinal clonidine at a dose of 1 μg kg−1 did not decrease blood measurements of troponin, cortisol, or lactate. Blood glucose suffered a more moderate variation during the procedure in the clonidine group. This fact, already reported in the literature, requires further investigation to be clarified.

    Simulator exercises are used at Midwestern University to augment academic and laboratory training toward consolidating particular skills, increasing situation awareness, and preparing the student for practice within the team environment of an operating room. This paper describes an enhanced cardiopulmonary bypass simulator consisting of a self-priming hemodynamic reservoir that includes an inline flow meter. A typical cardiopulmonary bypass adult perfusion circuit was assembled using a roller pump console and integrated oxygenator/heat exchanger/reservoir and primed with 2 liters of water. For patient simulation, a soft-sided reservoir bag was mounted onto an inclined platform. A 1-liter soft-sided bag was placed just above the reservoir, providing an overflow reservoir. The priming line extended to the head of the mannequin. The arterial, venous, and suction lines extended through the open chest. The primed perfusion circuit was connected to ports on the filled reservoir bag. To test the patient simulation, the arterial pump output was adjusted to flow rates ranging from 1-7 liters per minute, with a complete interruption (to zero flow) between each test run. An inline flow meter was added to the bypass circuit and an analog to digital converter board was used to pass flow data into the computer-based simulation program. The use of an inclined hemodynamic reservoir bag proved to be self-priming and functional without problems over a wide range of flows tested. By including a reservoir with the mannequin, plus processing and displaying real-time flow data using the CPB-Sim simulation program, a higher fidelity and more realistic simulation experience was created.

    2008-12-01

    Full Text Available Background: Cardiopulmonary exercise testing (CPX is a modern procedure that allows us to evaluate the global performanceof a subject. Because CPX devices are expensive and less popular due to a less amount of specialists in this field, many oflaboratories uses the more common ECG stress tests for physical performance assessment. Aim: to demonstrate theimportance and accuracy of cardiopulmonary exercise testing comparing with traditional maximal electrocardiographic (ECGstress test without gas exchange analysis. Methods: 18th elite soccer players (age 22.7±6 years, body mass 74.6±9.5 kg,height 175.4±9.8 cm participated in the study. The subjects accomplished two treadmill effort tests with and without gasanalyses, in 2 consecutive days interval. Results: At the end of the study we noticed a highly significant statistical difference(p<0.0001 between the investigated testing methods. In gas exchange testing method we found a decreased level of all theparameters evaluated comparing to stress ECG: VO2 peak (ml*kg-1*min-1 = 55.4±5.2 vs. 67.8±5.7; AT (ml*kg-1*min-1 =41.2±7.6 vs. 47.4±6.9; VO2/HR (ml = 23.8±2.5 vs. 23.8±2.5. Conclusions: Asessment of exercise performance based solelyon a maximal stress ECG without gas analyzing is inaccurate. Furthermore, estimation of peak exercise responses based uponcalculation of VO2 peak from peak work rate are inappropriate in sportsman. The study demonstrate once again that CPXremain the most accurate and reliable test for detection of AT and for a comprehensive physical performance assessment andcannot be replace by other surrogate laboratory exercise tests like stress ECG.

    Full Text Available Background: At low concentrations, carbon monoxide (CO can confer cyto and tissue-protective effects, such as endogenous Heme oxygenase 1 expression, which has antioxidative, anti-inflammatory, antiproliferative, and antiapoptotic effects. The level of carboxyhemoglobin in the blood is an indicator of the endogenous production of CO and inhaled CO. Aim of study: To investigate the significance of the value of carboxyhemoglobin for out-of-hospital (OH cardiopulmonary arrest (CPA. Materials and Methods: This study involved a medical chart review of cases treated from January to December 2005. The inclusion criteria included a patient who was transported to this department due to an OH CPA. The exclusion criteria included a patient who did not undergo blood gas analysis on arrival and who experienced CPA due to acute carbon monoxide intoxication. The subjects were divided into two groups based on their final outcome of either survival or non-survival. Results: There was no significant difference associated with the sex, age, frequency of witness collapse, bystander cardiopulmonary arrest, electrocardiogram at scene, cause of CPA, value of PCO 2 , HCO3 - , and methemoglobin. The frequency of OH return of spontaneous circulation and the value of pH, PO 2 , base excess, and carboxyhemoglobin in the survival group were greater than those values in the non-survival group. There were no subjects whose carboxyhemoglobin level was 0% on arrival in the survival groups. Conclusion: There appeared to be an association between higher carboxyhemoglobin levels and survival in comparison with non-survival patients.

    Full Text Available Despite efforts to save more people suffering from in-hospital cardiac arrest, rates of survival after in-hospital cardiopulmonary resuscitation (CPR are no better today than they were more than a decade ago. This study was undertaken to assess the demographics, clinical parameters and outcomes of patients undergoing CPR by the code blue team at our center during 2001 to 2008. Data were collected retrospectively from adult patients (n=2262 who underwent CPR. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from the hospital. Factors associated with survival were evaluated using binomial and Chi Square tests. Of the patients included (n=2262, 741 patients (32.8% had successful CPR. The number of male patients requiring CPR was more than females in need of the procedure. The majority of patients requiring CPR were older than 60 years (56.4±17.9. The number of successful CPR cases in long-day shift (7:00 to 19:00 was more than that in the night shift (19:00 to 7:00. Furthermore, 413 (18.4% cases were resuscitated on holidays and 1849 (81.7% on the working days. The duration of CPR was 10 min or less in 710 (31.4% cases. Cardiopulmonary resuscitations which lasted less than 10 minutes were associated with better outcomes. The findings of the present study indicate that some manageable factors including the duration of CPR, working shift, working day (holiday or non-holiday could affect the CPR outcomes. The findings might also be taken as evidence to suggest that the allocation of more personnel in each shift especially in night shifts and holidays, planning to increase the personnel's CPR skills, and decreasing the waste time would result in the improvement of CPR outcome.

    Significant efforts are invested by rescue agencies worldwide to save human lives during natural and man-made emergency situations including those that happen in wilderness locations. These emergency situations include but not limited to: accidents with alpinists, mountainous skiers, people hiking and lost in remote areas. Sometimes in a rescue operation hundreds of first responders are involved to save a single human life. There are two critical issues where geospatial imaging can be a very useful asset in rescue operations support: 1) human detection and 2) confirming a fact that detected a human being is alive. International group of researchers from the Unites States and Poland collaborated on a pilot research project devoted to identify a feasibility of use for the human detection and alive-human state confirmation small unmanned aerial vehicles (SUAVs) and inexpensive forward looking infrared (FLIR) sensors. Equipment price for both research teams was below 8,000 including 3DR quadrotor UAV and Lepton longwave infrared (LWIR) imager which costs around 250 (for the US team); DJI Inspire 1 UAS with commercial Tamarisc-320 thermal camera (for the Polish team). Specifically both collaborating groups performed independent experiments in the USA and Poland and shared imaging data of on the ground and airborne electro-optical and FLIR sensor imaging collected. In these experiments dead bodies were emulated by use of medical training dummies. Real humans were placed nearby as live human subjects. Electro-optical imagery was used for the research in optimal human detection algorithms. Furthermore, given the fact that a dead human body after several hours has a temperature of the surrounding environment our experiments were challenged by the SUAS data optimization, i.e., distance from SUAV to object so that the FLIR sensor is still capable to distinguish temperature differences between a dummy and a real human. Our experiments indicated feasibility of use SUAVs and

    Full Text Available A tragic disaster occurred on April 24, 2013, in Bangladesh, when a nine storied building in a suburban area collapsed and killed 1115 people and injured many more. The study describes the process of rescue operation and emergency management services provided in the event. Data were collected using qualitative methods including in-depth interviews and a focus group discussion with the involved medical students, doctors, volunteers, and local people. Immediately after the disaster, rescue teams came to the place from Bangladesh Armed Forces, Bangladesh Navy, Bangladesh Air Force, and Dhaka Metropolitan and local Police and doctors, medical students, and nurses from nearby medical college hospitals and private hospitals and students from colleges and universities including local civil people. Doctors and medical students provided 24-hour services at the disaster place and in hospitals. Minor injured patients were treated at health camps and major injured patients were immediately carried to nearby hospital. Despite the limitations of a low resource setting, Bangladesh faced a tremendous challenge to manage the man-made disaster and experienced enormous support from different sectors of society to manage the disaster carefully and saved thousands of lives. This effort could help to develop a standard emergency management system applicable to Bangladesh and other counties with similar settings.

    Amplitude of Ca(2+) transients, ultrastructure of Ca(2+) release units, and molecular composition of sarcoplasmic reticulum (SR) are altered in fast-twitch skeletal muscles of calsequestrin-1 (CASQ1)-null mice. To determine whether such changes are directly caused by CASQ1 ablation or are instead the result of adaptive mechanisms, here we assessed ability of CASQ1 in rescuing the null phenotype. In vivo reintroduction of CASQ1 was carried out by cDNA electro transfer in flexor digitorum brevis muscle of the mouse. Exogenous CASQ1 was found to be correctly targeted to the junctional SR (jSR), as judged by immunofluorescence and confocal microscopy; terminal cisternae (TC) lumen was filled with electron dense material and its width was significantly increased, as judged by electron microscopy; peak amplitude of Ca(2+) transients was significantly increased compared with null muscle fibers transfected only with green fluorescent protein (control); and finally, transfected fibers were able to sustain cytosolic Ca(2+) concentration during prolonged tetanic stimulation. Only the expression of TC proteins, such as calsequestrin 2, sarcalumenin, and triadin, was not rescued as judged by Western blot. Thus our results support the view that CASQ1 plays a key role in both Ca(2+) homeostasis and TC structure. PMID:22049211

  19. Rescue by peripheral blood mononuclear cells in dogs from bone marrow failure after total-body irradiation

    International Nuclear Information System (INIS)

    In order to determine the minimum dose of buffy coat cells necessary to achieve hematopoietic rescue following supralethal irradiation, mongrel dogs under general anesthesia were subjected to leukacytapheresis using three different techniques of cell separation. The buffy coats were frozen with dimethylsulfoxide and stored at -196 degrees C until transfused. Sixteen dogs were irradiated with 800 rads and were supported with antibiotics and transfusions of irradiated homologous blood. They were transfused with the frozen and thawed buffy coat cells, and, if they survived, they were followed for 100 days, sacrificed, and their tissues studied. The mean yield of mononuclear cells during leukocytapheresis ranged from 4.1 +/- 2.0 X 10(9) (mean +/- SD) to 6.0 +/- 4.0 X 10(9) for the three leukacytapheresis methods; one technique was not as satisfactory as the other two. Six of the 16 dogs fully recovered with evidence of marrow rescue; however, only one had a dose of mononuclear cells less than 11.1 X 10(9). These data indicate that seven to 17 leukacytapheresis procedures would be required to reconstitute a 70 kilogram patient. These preliminary findings suggest that, because the yields of transplantable cells with current technology are not adequate, the transplantation potential of buffy coat cells exposed to mobilizing agents should be evaluated

  20. Disease rescue and increased lifespan in a model of cardiomyopathy and muscular dystrophy by combined AAV treatments.

    Directory of Open Access Journals (Sweden)

    Carmen Vitiello

    Full Text Available BACKGROUND: The BIO14.6 hamster is an excellent animal model for inherited cardiomyopathy, because of its lethal and well-documented course, due to a spontaneous deletion of delta-sarcoglycan gene promoter and first exon. The muscle disease is progressive and average lifespan is 11 months, because heart slowly dilates towards heart failure. METHODOLOGY/PRINCIPAL FINDINGS: Based on the ability of adeno-associated viral (AAV vectors to transduce heart together with skeletal muscle following systemic administration, we delivered human delta-sarcoglycan cDNA into male BIO14.6 hamsters by testing different ages of injection, routes of administration and AAV serotypes. Body-wide restoration of delta-SG expression was associated with functional reconstitution of the sarcoglycan complex and with significant lowering of centralized nuclei and fibrosis in skeletal muscle. Motor ability and cardiac functions were completely rescued. However, BIO14.6 hamsters having less than 70% of fibers recovering sarcoglycan developed cardiomyopathy, even if the total rescued protein was normal. When we used serotype 2/8 in combination with serotype 2/1, lifespan was extended up to 22 months with sustained heart function improvement. CONCLUSIONS/SIGNIFICANCE: Our data support multiple systemic administrations of AAV as a general therapeutic strategy for clinical trials in cardiomyopathies and muscle disorders.

    The Skylab Program includes three low earth orbit missions. These missions are designated SL-1/SL-2,SL-3 and SL-4. In addition to the three nominal Skylab missions, the program includes the Skylab Rescue Mission (SL-R). The SL-R mission is designed to provide a safe return of the Skylab crew in the event the Command Service Module (CSM) becomes disabled while docked to the Saturn Workshop (SWS). Mission requirements for the SL-R mission only are presented. SL-R mission configuration will be a CSM (modified with a field installed kit) manned by two crewmen launched on a Saturn IB Launch Vechicle. The SL-R CSM will rendezvous and dock with the SWS (or Orbital Assembly (OA), consisting of the SWS and disabled CSM, if the disabled CSM has not previously been jettisoned). The SWS configuration includes a Multiple Docking Adapter (MDA), Apollo Telescope Mount (ATM), Airlock Module (AM), and an S-IVB stage (modified as an Orbital Workshop (OWS), previously launched and inserted into orbit on a two-stage Saturn V Launch Vehicle for the SL-1/SL-2 mission.

    Full Text Available We have previously shown that adenosine amine congener (ADAC, a selective A1 adenosine receptor agonist, can ameliorate noise- and cisplatin-induced cochlear injury. Here we demonstrate the dose-dependent rescue effects of ADAC on noise-induced cochlear injury in a rat model and establish the time window for treatment. Methods. ADAC (25–300 μg/kg was administered intraperitoneally to Wistar rats (8–10 weeks old at intervals (6–72 hours after exposure to traumatic noise (8–16 kHz, 110 dB sound pressure level, 2 hours. Hearing sensitivity was assessed using auditory brainstem responses (ABR before and 12 days after noise exposure. Pharmacokinetic studies investigated ADAC concentrations in plasma after systemic (intravenous administration. Results. ADAC was most effective in the first 24 hours after noise exposure at doses >50 μg/kg, providing up to 21 dB protection (averaged across 8–28 kHz. Pharmacokinetic studies demonstrated a short (5 min half-life of ADAC in plasma after intravenous administration without detection of degradation products. Conclusion. Our data show that ADAC mitigates noise-induced hearing loss in a dose- and time-dependent manner, but further studies are required to establish its translation as a clinical otological treatment.

    In this paper, we describe work in performance standards for urban search and rescue (USAR) robots begun in 2004 by the Department of Homeland Security. This program is being coordinated by the National Institute of Standards and Technology and will result in consensus standards developed through ASTM International, under the Operational Equipment Subcommittee of their Homeland Security Committee. The first phase of the program involved definition of requirements by subject matter experts. Responders participated in a series of workshops to identify deployment categories for robots, performance categories, and ranges of acceptable or target performance in the various categories. Over one hundred individual requirements were identified, within main categories such as Human-System Interaction, Logistics, Operating Environment, and System (which includes Chassis, Communications, Mobility, Payload, Power, and Sensing). To ensure that the robot developers and eventual end users work closely together, "responders meet robots" events at situationally relevant sites are being held to refine and extend the performance requirements and develop standard test methods. The results of these standard performance tests will be captured in a compendium of existing and developmental robots with classifications and descriptors to differentiate particular robotic capabilities. This, along with ongoing efforts to categorize situational USAR constraints such as building collapse types or the presence of hazardous materials, will help responders match particular robotic capabilities to response needs. In general, these efforts will enable responders to effectively use robotic tools to enhance their effectiveness while reducing risk to personnel during disasters.

    The objective of the present study was to compare the efficiency of two oocyte activation culture media to produce cloned dogs from an elite rescue dog and to analyze their behavioral tendencies. In somatic cell nuclear transfer procedure, fused couplets were activated by calcium ionophore treatment for 4 min, cultured in two media: modified synthetic oviduct fluid (mSOF) with 1.9 mmol/L 6-dimethylaminopyridine (DMAP) (SOF-DMAP) or porcine zygote medium (PZM-5) with 1.9 mmol/L DMAP (PZM-DMAP) for 4 h, and then were transferred into recipients. After embryo transfer, pregnancy was detected in one out of three surrogate mothers that received cloned embryos from the PZM-DMAP group (33.3%), and one pregnancy (25%) was detected in four surrogate mothers receiving cloned embryos from the SOF-DMAP group. Each pregnant dog gave birth to one healthy cloned puppy by cesarean section. We conducted the puppy aptitude test with two cloned puppies; the two cloned puppies were classified as the same type, accepting humans and leaders easily. The present study indicated that the type of medium used in 6-DMAP culture did not increase in cloning efficiency and dogs cloned using donor cells derived from one elite dog have similar behavioral tendencies.

    Full Text Available Abstract Objective To assess the theoretical and practical knowledge of the Glasgow Coma Scale (GCS by trained Air-rescue physicians in Switzerland. Methods Prospective anonymous observational study with a specially designed questionnaire. General knowledge of the GCS and its use in a clinical case were assessed. Results From 130 questionnaires send out, 103 were returned (response rate of 79.2% and analyzed. Theoretical knowledge of the GCS was consistent for registrars, fellows, consultants and private practitioners active in physician-staffed helicopters. The clinical case was wrongly scored by 38 participants (36.9%. Wrong evaluation of the motor component occurred in 28 questionnaires (27.2%, and 19 errors were made for the verbal score (18.5%. Errors were made most frequently by registrars (47.5%, p = 0.09, followed by fellows (31.6%, p = 0.67 and private practitioners (18.4%, p = 1.00. Consultants made significantly less errors than the rest of the participating physicians (0%, p Conclusion Although the theoretical knowledge of the GCS by out-of-hospital physicians is correct, significant errors were made in scoring a clinical case. Less experienced physicians had a higher rate of errors. Further emphasis on teaching the GCS is mandatory.

    Full Text Available Indonesia is among the developing countries that are struggling to develop in the field of industrial development. The logical consequence of any development process, especially industrial development is the emergence of associated impacts that greatly affect the durability and sustainability of the environment. Developing the equitable industry in order to create public welfare is important. However, maintaining the security and preservation of the environment is also very important, because it is only with the availability of a good environment and healthy living that human beings can perform daily living. The availability of good and healthy environment is the constitutional responsibility of the government, as well as part of the human rights of all citizens which must be given by the State. Efforts to create a good environment and healthy living will be effective if controlled by State government and institutions who understand the objective conditions on the ground. In this regard, the granting of the authority on environmental control to regional government autonomously is the right, very smart policy choice. How To Cite: Sutrisno, B. (2016.

    Management of a large mediastinal mass causing respiratory and hemodynamic compromise represents a major challenge during induction of anesthesia and surgical resection. The hemodynamic changes associated with anesthetic induction and initiation of positive-pressure ventilation can lead to acute hemodynamic collapse or inability to ventilate, or both. Initiation of cardiopulmonary bypass before anesthetic induction represents a safe alternative. We present a 37-year-old woman who underwent successful resection of a large anterior mediastinal mass through sternotomy. Cardiopulmonary bypass was instituted using the right femoral vessels under local analgesia to allow safe anesthetic induction. Her postoperative course was uneventful. This represents an example of a team approach to the management of a complex patient to achieve a successful outcome. PMID:25282247

    Full Text Available Objective: to evaluate and compare the frequency of nursing diagnosis activity intolerance and ineffective cardiopulmonary tissue perfusion in advanced ischemic heart disease patients before and after gene therapy for myocardial revascularization. Methods: cohort study, in which 20 patients developed ischemic heart disease treated with gene therapy are undergoing clinical evaluation of two nurses with experience of minimum three years in cardiology, to identify the presence or absence of the nursing diagnosis activity intolerance and ineffective cardiopulmonary tissue perfusion. These evaluations will be done before gene therapy and three and six months afterwards. The data will be tabulated for later analysis of absolute and relative frequency as well as comparison between the three moments. Will be used for the coefficient of Kappa analysis of agreement between the assessments of nursing. To compare the dichotomous variables will be used for the Cochran Q-test and for ordinal variables will be used the Friedman test.

    Apart from the safety requirements stated in DIN 23320 for flameproof clothing for mine rescue and gas protection personnel, also the wearing properties of these suits is important. Flameproof suits must be worn either for an 8-hour shift under normal working conditions or for the periods stated in the relevant regulations under unfavourable conditions in order to qualify as flame protection clothing. The wearing characteristics of flameproof suits for mine rescue and gas protection personnel according to DIN 23320 (2) under unfavourable climatic conditions were investigated at the Saar Central Office for Mine Rescue; the flameproof suits Proban, FPT, Nomex, and Pyrovatex were tested. Methods of measurement and criteria of assessment are described in detail. The findings suggest that the Nomex-III suit should be recommended as flameproof suit for mine rescue and gas protection personnel.

    Choclo virus (CHOV) was described in sigmodontine rodents, Oligoryzomys fulvescens, and humans during an outbreak of hantavirus cardiopulmonary syndrome (HCPS) in 1999 to 2000 in western Panama. Although HCPS is rare, hantavirus-specific serum antibody prevalence among the general population is high suggesting that CHOV may cause many mild or asymptomatic infections. The goals of this study were to confirm the role of CHOV in HCPS and in the frequently detected serum antibody and to establish...
