  • Deaths from international terrorism compared with road crash deaths in OECD countries.


    Wilson, N; Thomson, G


    To estimate the relative number of deaths in member countries of the Organisation for Economic Co-operation and Development (OECD) from international terrorism and road crashes. Data on deaths from international terrorism (US State Department database) were collated (1994-2003) and compared to the road injury deaths (year 2000 and 2001 data) from the OECD International Road Transport Accident Database. In the 29 OECD countries for which comparable data were available, the annual average death rate from road injury was approximately 390 times that from international terrorism. The ratio of annual road to international terrorism deaths (averaged over 10 years) was lowest for the United States at 142 times. In 2001, road crash deaths in the US were equal to those from a September 11 attack every 26 days. There is a large difference in the magnitude of these two causes of deaths from injury. Policy makers need to be aware of this when allocating resources to preventing these two avoidable causes of mortality.

  • Sibling death and death fear in relation to depressive symptomatology in older adults.


    Cicirelli, Victor G


    Previously overlooked factors in elders' depressive symptomatology were examined, including death fear, sibling death, and sibling closeness. Participants were 150 elders (61 men, 89 women) aged 65-97 years with at least one sibling. Measures were proportion of deceased siblings, sibling closeness, the Death Fear Subscale of the Death Attitude Profile-Revised, and the Center for Epidemiological Studies-Depression scale (20-item adult form). Age and education were exogenous variables in a structural equation model. Death fear, sibling closeness, and proportion of dead siblings were directly related to depression, with path coefficients of .42, -.24, and .13, respectively. Proportion of dead siblings had indirect effects on depression, as did age and education. Depressive symptomatology in old age is influenced by death fear related to sibling death as well as by poor relationships with them; it must be understood within a situational context including death fear and sibling relationships.

  • Complete positive ion, electron, and ram negative ion measurements near Comet Halley (COPERNIC) plasma experiment for the European Giotto Mission

    NASA Technical Reports Server (NTRS)

    Lin, Robert P.


    Participation of U.S. scientists on the COPERNIC (COmplete Positive ions, Electrons and Ram Negative Ion measurements near Comet Halley) plasma experiment on the Giotto mission is described. The experiment consisted of two detectors: the EESA (electron electrostatic analyzer) which provided three-dimensional measurements of the distribution of electrons from 10 eV to 30 keV, and the PICCA (positive ion cluster composition analyzer) which provided mass analysis of positively charged cold cometary ions from mass 10 to 210 amu. In addition, a small 3 deg wide sector of the EESA looking in the ram direction was devoted to the detection of negatively charged cold cometary ions. Both detectors operated perfectly up to near closest approach (approx. 600 km) to Halley, but impacts of dust particles and neutral gas on the spacecraft contaminated parts of the data during the last few minutes. Although no flight hardware was fabricated in the U.S., The U.S. made very significant contributions to the hardware design, ground support equipment (GSE) design and fabrication, and flight and data reduction software required for the experiment, and also participated fully in the data reduction and analysis, and theoretical modeling and interpretation. Cometary data analysis is presented.

    Lane, Kathryn; Ito, Kazuhiko; Johnson, Sarah; Gibson, Elizabeth A.; Matte, Thomas


    Exposure to cold weather can cause cold-related illness and death, which are preventable. To understand the current burden, risk factors, and circumstances of exposure for illness and death directly attributed to cold, we examined hospital discharge, death certificate, and medical examiner data during the cold season from 2005 to 2014 in New York City (NYC), the largest city in the United States. On average each year, there were 180 treat-and-release emergency department visits (average annual rate of 21.6 per million) and 240 hospital admissions (29.6 per million) for cold-related illness, and 15 cold-related deaths (1.8 per million). Seventy-five percent of decedents were exposed outdoors. About half of those exposed outdoors were homeless or suspected to be homeless. Of the 25% of decedents exposed indoors, none had home heat and nearly all were living in single-family or row homes. The majority of deaths and illnesses occurred outside of periods of extreme cold. Unsheltered homeless individuals, people who use substances and become incapacitated outdoors, and older adults with medical and psychiatric conditions without home heat are most at risk. This information can inform public health prevention strategies and interventions. PMID:29601479

    (Video) Scientists Finally Try to Explain Near Death Experiences

  • Prolonged disengagement from distractors near the hands

    PubMed Central

    Vatterott, Daniel B.; Vecera, Shaun P.


    Because items near our hands are often more important than items far from our hands, the brain processes visual items near our hands differently than items far from our hands. Multiple experiments have attributed this processing difference to spatial attention, but the exact mechanism behind how spatial attention near our hands changes is still under investigation. The current experiments sought to differentiate between two of the proposed mechanisms: a prioritization of the space near the hands and a prolonged disengagement of spatial attention near the hands. To differentiate between these two accounts, we used the additional singleton paradigm in which observers searched for a shape singleton among homogenously shaped distractors. On half the trials, one of the distractors was a different color. Both the prioritization and disengagement accounts predict differently colored distractors near the hands will slow target responses more than differently colored distractors far from the hands, but the prioritization account also predicts faster responses to targets near the hands than far from the hands. The disengagement account does not make this prediction, because attention does not need to be disengaged when the target appears near the hand. We found support for the disengagement account: Salient distractors near the hands slowed responses more than those far from the hands, yet observers did not respond faster to targets near the hands.

  • Child deaths with persistent neglected experiences from medico-legal documents in Japan.


    Yamaoka, Yui; Tamiya, Nanako; Fujiwara, Takeo; Yamasaki, Yukie; Matsuzawa, Akemi; Miyaishi, Satoru


    Few studies have examined the actual conditions of fatal neglect in Japan. The aims of this study were to investigate persistent neglect among child fatalities using medico-legal documents, and to describe the characteristics of the socio-familial background and biological data. The current study analyzed the documents of all postmortem external examinations and autopsies in children <2 years old carried out in one prefecture in Japan from 2006 to 2011. After examining 59 autopsy cases using modified the Maltreatment Classification System, we identified six children who experienced persistent neglect as study samples. Three children were found in unsanitary rooms and one was left alone inside a car. In two cases, age of mother at delivery was <21 years old. Three victims had 1 year older sibling. With regard to history of use of health services, three mothers missed some prenatal care visits, and two refused to receive neonatal home visits. With regard to biological data the average weight Z score of six children was -2.22 after being adjusted to average weight for age (in months) and sex. Three children had acute or chronic undernutrition. Three victims had thymic involution considered as being due to chronic child maltreatment. The present collaboration between public health and legal medicine has enabled investigation of the background and biological impact of experiences of persistent neglect. A multidisciplinary system of evaluating child death is needed to identify preventable factors in order to intervene in the case of neglected children in a timely manner. © 2014 The Authors.

    Over the past decade, the Nomenclature Committee on Cell Death (NCCD) has formulated guidelines for the definition and interpretation of cell death from morphological, biochemical, and functional perspectives. Since the field continues to expand and novel mechanisms that orchestrate multiple cell death pathways are unveiled, we propose an updated classification of cell death subroutines focusing on mechanistic and essential (as opposed to correlative and dispensable) aspects of the process. As we provide molecularly oriented definitions of terms including intrinsic apoptosis, extrinsic apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, entotic cell death, NETotic cell death, lysosome-dependent cell death, autophagy-dependent cell death, immunogenic cell death, cellular senescence, and mitotic catastrophe, we discuss the utility of neologisms that refer to highly specialized instances of these processes. The mission of the NCCD is to provide a widely accepted nomenclature on cell death in support of the continued development of the field.

  • Declining incidence in fall-induced deaths of older adults: Finnish statistics during 1971-2015.


    Kannus, Pekka; Niemi, Seppo; Sievänen, Harri; Parkkari, Jari


    Fall-induced deaths of elderly people are a major problem. Using the Official Cause-of-Death Statistics of Finland, we aimed to determine the current trends in the number and age-adjusted incidence (per 100,000 persons) of fall deaths among older Finns by taking into account 50 years or older persons who died because of a fall-induced injury in 1971-2015. Among men, the number of fall-induced deaths increased considerably between 1971 and 2003 (from 162 in 1971 to 564 in 2003), while thereafter, this number has been relatively stable (579 deaths in 2015). Men's age-adjusted incidence of fall deaths rose from 45.6 in 1971 to 69.5 in 1998, after which it stayed relatively stable until 2005 (69.9). Since 2005, this figure has shown a steady, deep decline (only 45.1 in 2015). Among women, the number of fall-induced deaths increased considerably between 1971 and 1998 (from 279 in 1971 to 563 in 1998), while thereafter, this number has been relatively stable (532 deaths in 2015). In sharp contrast to men, women's age-adjusted incidence of fall-induced deaths has been declining since the early 1970s, the incidence being 82.6 in 1971 while only 33.0 in 2015. A steady, deep decline started in 1998. Among 50 years or older Finns the number of fall-induced deaths increased considerably from the early 1970s until the late 1990s but stabilized thereafter. In the new millennium, the age-adjusted incidence of these deaths has started to decline in both sexes. Despite this we have to effectively continue the falls prevention efforts, because our elderly population will grow rapidly in the near future.

  • Histological and Finite Element Analysis of Cell Death due to Irreversible Electroporation

    PubMed Central

    Long, G.; Bakos, G.; Shires, P. K.; Gritter, L.; Crissman, J. W.; Harris, J. L.; Clymer, J. W.


    Irreversible electroporation (IRE) has been shown to be an effective method of killing cells locally. In contrast to radiofrequency ablation, the mechanism by which cells are thought to die via IRE is the creation of pores in cell membranes, without substantial increase in tissue temperature. To determine the degree to which cell death is non-thermal, we evaluated IRE in porcine hepatocytes in vivo. Using pulse widths of 10μs, bursts of 3 kV square-wave pulses were applied through a custom probe to the liver of an anesthetized pig. Affected tissue was evaluated histologically via stainings of hematoxylin & eosin (H&E), nitroblue tetrazolium (NBT) to monitor cell respiration and TUNEL to gauge apoptosis. Temperature was measured during the application of electroporation, and heat transfer was modeled via finite element analysis. Cell death was calculated via Arrhenius kinetics. Four distinct zones were observed within the ring return electrode; heat-fixed tissue, coagulation, necrotic, and viable. The Arrhenius damage integral estimated complete cell death only in the first zone, where the temperature exceeded 70°C, and partial or no cell death in the other zones, where maximum temperature was approximately 45°C. Except for a limited area near the electrode tip, cell death in IRE is predominantly due to a non-thermal mechanism. PMID:24000980

  • Medical neglect death due to acute lymphoblastic leukaemia: an autopsy case report.


    Usumoto, Yosuke; Sameshima, Naomi; Tsuji, Akiko; Kudo, Keiko; Nishida, Naoki; Ikeda, Noriaki


    We report the case of 2-year-old girl who died of precursor B-cell acute lymphoblastic leukaemia (ALL), the most common cancer in children. She had no remarkable medical history. She was transferred to a hospital because of respiratory distress and died 4 hours after arrival. Two weeks before death, she had a fever of 39 degrees C, which subsided after the administration of a naturopathic herbal remedy. She developed jaundice 1 week before death, and her condition worsened on the day of death. Laboratory test results on admission showed a markedly elevated white blood cell count. Accordingly, the cause of death was suspected to be acute leukaemia. Forensic autopsy revealed the cause of death to be precursor B-cell ALL. With advancements in medical technology, the 5-year survival rate of children with ALL is nearly 90%. However, in this case, the deceased's parents preferred complementary and alternative medicine (i.e., naturopathy) to evidence-based medicine and had not taken her to a hospital for a medical check-up or immunisation since she was an infant. Thus, if she had received routine medical care, she would have a more than 60% chance of being alive 5 years after diagnosis. Therefore, we conclude that the parents should be accused of medical neglect regardless of their motives.

  • Cell death proteomics database: consolidating proteomics data on cell death.


    Arntzen, Magnus Ø; Bull, Vibeke H; Thiede, Bernd


    Programmed cell death is a ubiquitous process of utmost importance for the development and maintenance of multicellular organisms. More than 10 different types of programmed cell death forms have been discovered. Several proteomics analyses have been performed to gain insight in proteins involved in the different forms of programmed cell death. To consolidate these studies, we have developed the cell death proteomics (CDP) database, which comprehends data from apoptosis, autophagy, cytotoxic granule-mediated cell death, excitotoxicity, mitotic catastrophe, paraptosis, pyroptosis, and Wallerian degeneration. The CDP database is available as a web-based database to compare protein identifications and quantitative information across different experimental setups. The proteomics data of 73 publications were integrated and unified with protein annotations from UniProt-KB and gene ontology (GO). Currently, more than 6,500 records of more than 3,700 proteins are included in the CDP. Comparing apoptosis and autophagy using overrepresentation analysis of GO terms, the majority of enriched processes were found in both, but also some clear differences were perceived. Furthermore, the analysis revealed differences and similarities of the proteome between autophagosomal and overall autophagy. The CDP database represents a useful tool to consolidate data from proteome analyses of programmed cell death and is available at

  • The case for a sociology of dying, death, and bereavement.


    Thompson, Neil; Allan, June; Carverhill, Philip A; Cox, Gerry R; Davies, Betty; Doka, Kenneth; Granek, Leeat; Harris, Darcy; Ho, Andy; Klass, Dennis; Small, Neil; Wittkowski, Joachim


    Dying, death, and bereavement do not occur in a social vacuum. How individuals and groups experience these phenomena will be largely influenced by the social context in which they occur. To develop an adequate understanding of dying, death, and bereavement we therefore need to incorporate a sociological perspective into our analysis. This article examines why a sociological perspective is necessary and explores various ways in which sociology can be of practical value in both intellectual and professional contexts. A case study comparing psychological and sociological perspectives is offered by way of illustration.

  • Potentially preventable deaths from the five leading causes of death--United States, 2008-2010.


    Yoon, Paula W; Bastian, Brigham; Anderson, Robert N; Collins, Janet L; Jaffe, Harold W


    In 2010, the top five causes of death in the United States were 1) diseases of the heart, 2) cancer, 3) chronic lower respiratory diseases, 4) cerebrovascular diseases (stroke), and 5) unintentional injuries. The rates of death from each cause vary greatly across the 50 states and the District of Columbia (2). An understanding of state differences in death rates for the leading causes might help state health officials establish disease prevention goals, priorities, and strategies. States with lower death rates can be used as benchmarks for setting achievable goals and calculating the number of deaths that might be prevented in states with higher rates. To determine the number of premature annual deaths for the five leading causes of death that potentially could be prevented ("potentially preventable deaths"), CDC analyzed National Vital Statistics System mortality data from 2008-2010. The number of annual potentially preventable deaths per state before age 80 years was determined by comparing the number of expected deaths (based on average death rates for the three states with the lowest rates for each cause) with the number of observed deaths. The results of this analysis indicate that, when considered separately, 91,757 deaths from diseases of the heart, 84,443 from cancer, 28,831 from chronic lower respiratory diseases, 16,973 from cerebrovascular diseases (stroke), and 36,836 from unintentional injuries potentially could be prevented each year. In addition, states in the Southeast had the highest number of potentially preventable deaths for each of the five leading causes. The findings provide disease-specific targets that states can use to measure their progress in preventing the leading causes of deaths in their populations.

  • Mortality and causes of death after traumatic spinal cord injury in Estonia

    PubMed Central

    Sabre, Liis; Rekand, Tiina; Asser, Toomas; Kõrv, Janika


    Study design Retrospective population-based study with mortality follow-up. Objective To study mortality, causes and risk factors for death in Estonian patients with traumatic spinal cord injury (TSCI). Setting All Estonian hospitals. Methods Medical records of patients with TSCI from all regional, central, general, and rehabilitation hospitals in Estonia from 1997 to 2007, were retrospectively reviewed. Mortality status was ascertained as of 31 December 2011. Causes of death were collected from the Estonian Causes of Death Registry. Standardized mortality ratios (SMRs) were calculated for the entire sample and for causes of death. A Cox proportional hazards modeling was used to identify the risk indicators for death. Results During the observation period (1997–2011) 162 patients of 595 died. Nearly half of the patients (n=76) died during the first year after TSCI. The main causes of death were external causes (30%), cardiovascular disease (29%). and suicide (8%). The overall SMR was 2.81 (95% confidence interval 2.40–3.28) and SMR was higher for women than for men (3.80 vs. 2.70). Cause-specific SMRs were markedly elevated for sepsis and suicide. Mortality was significantly affected by the age at the time of injury, neurological level, and extent of the injury as well as the year of TSCI and complications. Conclusion Life expectancy is significantly decreased in patients with TSCI in Estonia compared with the general population. Deaths during the first year after the injury have an important impact on statistics. Treatment of cardiovascular diseases, infections, and prevention of suicide are useful for reducing mortality in patients with TSCI. PMID:24090049

  • Discrete and continuum simulations of near-field ground motion from Source Physics Experiments (SPE) (Invited)

    NASA Astrophysics Data System (ADS)

    Ezzedine, S. M.; Vorobiev, O.; Herbold, E. B.; Glenn, L. A.; Antoun, T.


    This work is focused on analysis of near-field measurements (up to 100 m from the source) recorded during Source Physics Experiments in a granitic formation. One of the main goals of these experiments is to investigate the possible mechanisms of shear wave generation in the nonlinear source region. SPE experiments revealed significant tangential motion (up to 30 % of the magnitude in the radial direction) at many locations. Furthermore, azimuthal variations in radial velocities were also observed which cannot be generated by a spherical source in isotropic materials. Understanding the nature of this non-radial motion is important for discriminating between the natural seismicity and underground explosions signatures. Possible mechanisms leading to such motion include, but not limited to, heterogeneities in the rock such as joints, faults and geologic layers as well as surface topography and vertical motion at the surface caused by material spall and gravity. We have performed a three dimensional computational studies considering all these effects. Both discrete and continuum methods have been employed to model heterogeneities. In the discrete method, the joints and faults were represented by cohesive contact elements. This enables us to examine various friction laws at the joints which include softening, dilatancy, water saturation and rate-dependent friction. Yet this approach requires the mesh to be aligned with joints, which may present technical difficulties in three dimensions when multiple non-persistent joints are present. In addition, the discrete method is more computationally expensive. The continuum approach assumes that the joints are stiff and the dilatancy and shear softening can be neglected. In this approach, the joints are modeled as weakness planes within the material, which are imbedded into and pass through many finite elements. The advantage of this approach is that it requires neither sophisticated meshing algorithms nor contact detection

  • 'Death is difficult in any language': A qualitative study of palliative care professionals' experiences when providing end-of-life care to patients from culturally and linguistically diverse backgrounds.

    (Video) The Near Death Experience in Plato's Republic (NDE of Er and why Plato included it);


    Green, Anna; Jerzmanowska, Natalia; Green, Marguerite; Lobb, Elizabeth A


    Ethnic minority patients have unique challenges in accessing health services. These include language difficulties, unfamiliarity with the health system, lower rates of cancer screening and survival, higher rates of reported side effects from cancer treatment and poorer quality of life. Little is known about this patient group when transitioning to palliative care. To elicit the experiences of palliative care health professionals when providing care for patients from culturally and linguistically diverse backgrounds which differ from mainstream Australian language and culture. An emergent qualitative design, informed by theoretical and procedural direction from grounded theory research. Four focus groups held with palliative care staff ( n = 28) in a single specialist palliative care service in Australia. The following themes emerged: (1) determining the rules of engagement around discussion of diagnosis and prognosis, (2) navigating the challenge of language to patient understanding, (3) understanding migration experiences to establish trust, (4) maintaining the balance between patient safety and comfort care, (5) providing a good death experience through accommodation of beliefs, and (6) navigating the important role of family members while privileging patient preferences. Underlying provider perceptions of caring for patients was that death is difficult in any language. Care was conceptualised as considering cultural and linguistic backgrounds within individualistic care. Understanding the migration experience and building trust were key elements of this individualised approach. Acknowledgement of the key role played by families in patient care and safety are strategies to minimise barriers and understand the concerns of this patient group.

  • Quantum effects in amplitude death of coupled anharmonic self-oscillators

    NASA Astrophysics Data System (ADS)

    Amitai, Ehud; Koppenhöfer, Martin; Lörch, Niels; Bruder, Christoph


    Coupling two or more self-oscillating systems may stabilize their zero-amplitude rest state, therefore quenching their oscillation. This phenomenon is termed "amplitude death." Well known and studied in classical self-oscillators, amplitude death was only recently investigated in quantum self-oscillators [Ishibashi and Kanamoto, Phys. Rev. E 96, 052210 (2017), 10.1103/PhysRevE.96.052210]. Quantitative differences between the classical and quantum descriptions were found. Here, we demonstrate that for quantum self-oscillators with anharmonicity in their energy spectrum, multiple resonances in the mean phonon number can be observed. This is a result of the discrete energy spectrum of these oscillators, and is not present in the corresponding classical model. Experiments can be realized with current technology and would demonstrate these genuine quantum effects in the amplitude death phenomenon.

  • 'Natural' and 'Unnatural' medical deaths and coronial law: A UK and international review of the medical literature on natural and unnatural death and how it applies to medical death certification and reporting deaths to coroners: Natural/Unnatural death: A Scientific Review.


    Harris, Andrew


    In the United Kingdom, when people die, either a doctor writes an acceptable natural cause of death medical certificate, or a coroner (fiscal in Scotland) investigates the case, usually with an autopsy. An inquest may or may not follow. The concept of 'natural or unnatural cause' death is not internationally standardized. This article reviews scientific evidence as to what is a natural death or unnatural death and how that relates to the international classification of deaths. Whilst there is some consensus on the definition, its application in considering whether to report to the coroner is more difficult. Depictions of deaths in terminal care, medical emergencies and post-operative care highlight these difficulties. It secondly reviews to what extent natural and unnatural are criteria for notification of deaths in England and Wales and internationally. It concludes with consideration of how medical concepts of unnatural death relate in England and Wales to coroners' legal concepts of what is unnatural. Deaths that appear natural to clinicians and pathologists may be legally unnatural and vice versa. It is argued that the natural/unnatural dichotomy is not a good criterion for reporting deaths under medical care to coroners, but the notification of a medical cause of death, using the International Classification of Disease Codes and the medical professional view as to whether it is scientifically natural, is of great value to the coroner in deciding whether it is legally unnatural.

  • Mortality salience and morality: thinking about death makes people less utilitarian.


    Trémolière, Bastien; Neys, Wim De; Bonnefon, Jean-François


    According to the dual-process model of moral judgment, utilitarian responses to moral conflict draw on limited cognitive resources. Terror Management Theory, in parallel, postulates that mortality salience mobilizes these resources to suppress thoughts of death out of focal attention. Consequently, we predicted that individuals under mortality salience would be less likely to give utilitarian responses to moral conflicts. Two experiments corroborated this hypothesis. Experiment 1 showed that utilitarian responses to non-lethal harm conflicts were less frequent when participants were reminded of their mortality. Experiment 2 showed that the detrimental effect of mortality salience on utilitarian conflict judgments was comparable to that of an extreme concurrent cognitive load. These findings raise the question of whether private judgment and public debate about controversial moral issues might be shaped by mortality salience effects, since these issues (e.g., assisted suicide) often involve matters of life and death.

  • FAQs

    What are the three near-death experiences? ›

    Yvonne Kason MD classified near-death experiences into three types: the "Out-of-Body" type, the "Mystical" or "White-Light" type, and the "Distressing" type.

    What are the stages of the near-death experience? ›

    Ring (1980) classified the unfolding stages of the NDE into (a) peace and well-being; (b) separation from the physical body; (c) entering a transitional region of darkness; (d) seeing a brilliant light; and (e) entering, through the light, another realm of existence.

    What are memories of near-death experience? ›

    Memories of near-death experiences were more vivid and detailed than of real events. Near-death experiences were thus remembered as “more real” than were real events. Near-death experiences were remembered as hyperreal and not as imagined events.

    What is the science of death and dying? ›

    Thanatology is the scientific study of death and the losses brought about as a result. It investigates the mechanisms and forensic aspects of death, such as bodily changes that accompany death and the postmortem period, as well as wider psychological and social aspects related to death.
