Epidemiological information is lacking for driving under the influence of alcohol (DUI) in Puerto Rico. To examine the prevalence and correlates of DUI in Puerto Rico. Data are from a household sample of 1510 individuals, aged 18-64 years in San Juan, Puerto Rico. The response rate was 83%. The rate of 12 month self-reported DUI was 20% among men and 8% among women (p Puerto Rico was high, but the proportion of people arrested for DUI in a span of 12 months or during their lifetime was low. Stricter enforcement of DUI laws may be necessary to minimize DUI in urban Puerto Rico.

We examined effects of state statutory changes in DUI fine or jail penalties for firsttime offenders from 1976 to 2002. A quasi-experimental time-series design was used (n=324 monthly observations). Four outcome measures of drivers involved in alcohol-related fatal crashes are: single-vehicle nighttime, low BAC (0.01-0.07g/dl), medium BAC (0.08-0.14g/dl), high BAC (>/=0.15g/dl). All analyses of BAC outcomes included multiple imputation procedures for cases with missing data. Comparison series of non-alcohol-related crashes were included to efficiently control for effects of other factors. Statistical models include state-specific Box-Jenkins ARIMA models, and pooled general linear mixed models. Twenty-six states implemented mandatory minimum fine policies and 18 states implemented mandatory minimum jail penalties. Estimated effects varied widely from state to state. Using variance weighted meta-analysis methods to aggregate results across states, mandatory fine policies are associated with an average reduction in fatal crash involvement by drivers with BAC>/=0.08g/dl of 8% (averaging 13 per state per year). Mandatory minimum jail policies are associated with a decline in single-vehicle nighttime fatal crash involvement of 6% (averaging 5 per state per year), and a decline in low-BAC cases of 9% (averaging 3 per state per year). No significant effects were observed for the other outcome measures. The overall pattern of results suggests a possible effect of mandatory fine policies in some states, but little effect of mandatory jail policies.

This study identifies social mechanisms that might help prevent youth from being involved in driving under the influence of alcohol (DUI) and riding with drinking drivers (RWDD). Data collected through telephone surveys with 1534 adolescents and young adults aged 15-20 years (mean=17.6, S.D.=1.6) in California, USA, were analyzed. Structural equation modeling analyses showed that DUI and RWDD were strongly related to drinking in unstructured situations, modeling of DUI by peers and parents, and perceived peer approval or disapproval of DUI. DUI outcome expectancies were indirectly related to DUI and RWDD through situational drinking. Parental monitoring and DUI law enforcement were also indirectly related to DUI and RWDD through DUI expectancies and other mechanisms. The findings, overall, suggest that parental influence remains important even through late adolescence. Parental monitoring, in particular, might help to reduce unstructured socializing with peers, drinking, and affiliation with peers who engage in DUI. Parental monitoring may also foster beliefs about the risks of DUI. Conversely, parents' own DUI behavior may normalize drinking and DUI behaviors, thus countering monitoring efforts.

This study aimed to estimate the prevalence of driving after drinking (DUI) and its associated factors in low and high alcohol outlet density areas (LAOD and HAOD) in Porto Alegre, Brazil. A probability 3-stage sampling survey was conducted, and 683 drivers who were leaving alcohol outlets (AOs) and had been drinking were interviewed, breathalyzed and saliva was collected for drug screening. Prevalences were assessed using domain estimation and DUI predictors were assessed using logistic models. results: It was estimated that 151,573 drivers drank at the AO, and intention to DUI was more prevalent in LAOD (59.3 versus 46.1% in HAOD, P = 0.003). On the other hand, HAOD had higher proportions of interviewees with a blood alcohol concentration (BAC) of >0.06% (46.6 versus 30.7%, P = 0.002) as well as a more frequent use of cocaine (9.3 versus 2.4%, P = 0.086). In the logistic models, drinking in a LAOD stratum was found to be associated with DUI (OR 1.72 (1.17-2.5)) and the two AO density areas presented different factors independently associated with DUI: THC use was significantly associated with the outcome in the HAOD stratum (OR 17.7 (5.1-61.8)), whereas an AUDIT score of >20 was positively associated with DUI in LAOD (OR 23.75 (1.5-364.0)). High prevalences of driving under the influence of alcohol were evident in both the high and the low outlet density areas, although with different characteristics. Thorough enforcement of the legislation by random breath testing and sobriety checkpoints should be combined with AO licensing in order to reduce high levels of DUI and traffic accidents.

Studies demonstrating that higher doses of citalopram (> 40 mg) and escitalopram (> 20 mg) prolong the corrected QT interval prompted regulatory agency warnings, which are controversial, given the absence of confirmatory clinical outcome studies. We compared the risk of potential arrhythmia-related deaths for high doses of these selective serotonin reuptake inhibitors (SSRIs) to that for equivalent doses of fluoxetine, paroxetine, and sertraline. The Tennessee Medicaid retrospective cohort study included 54,220 persons 30-74 years of age without cancer or other life-threatening illness who were prescribed high-dose SSRIs from 1998 through 2011. The mean age was 47 years, and 76% were female. Demographic characteristics and comorbidity for individual SSRIs were comparable. Because arrhythmia-related deaths are typically sudden and occur outside the hospital, we analyzed out-of-hospital sudden unexpected death as well as sudden cardiac deaths, a more specific indicator of proarrhythmic effects. The adjusted risk of sudden unexpected death for citalopram did not differ significantly from that for the other SSRIs. The respective hazard ratios (HRs) for citalopram versus escitalopram, fluoxetine, paroxetine, and sertraline were 0.84 (95% CI, 0.40-1.75), 1.24 (95% CI, 0.75-2.05), 0.75 (95% CI, 0.45-1.24), and 1.53 (95% CI, 0.91-2.55). There were no significant differences for sudden cardiac death or all study deaths, nor were there significant differences among high-risk patients (≥ 60 years of age, upper quartile baseline cardiovascular risk). Escitalopram users had no significantly increased risk for any study end point. We found no evidence that risk of sudden unexpected death, sudden cardiac death, or total mortality for high-dose citalopram and escitalopram differed significantly from that for comparable doses of fluoxetine, paroxetine, and sertraline. © Copyright 2016 Physicians Postgraduate Press, Inc.

A High-Throughput Small Molecule Screen for C. elegans Linker Cell Death Inhibitors.

Directory of Open Access Journals (Sweden)

Andrew R Schwendeman

Full Text Available Programmed cell death is a ubiquitous process in metazoan development. Apoptosis, one cell death form, has been studied extensively. However, mutations inactivating key mammalian apoptosis regulators do not block most developmental cell culling, suggesting that other cell death pathways are likely important. Recent work in the nematode Caenorhabditis elegans identified a non-apoptotic cell death form mediating the demise of the male-specific linker cell. This cell death process (LCD, linker cell-type death is morphologically conserved, and its molecular effectors also mediate axon degeneration in mammals and Drosophila. To develop reagents to manipulate LCD, we established a simple high-throughput screening protocol for interrogating the effects of small molecules on C. elegans linker cell death in vivo. From 23,797 compounds assayed, 11 reproducibly block linker cell death onset. Of these, five induce animal lethality, and six promote a reversible developmental delay. These results provide proof-of principle validation of our screening protocol, demonstrate that developmental progression is required for linker cell death, and suggest that larger scale screens may identify LCD-specific small-molecule regulators that target the LCD execution machinery.

Endothelial death is critical in diabetic vascular diseases, but regulating factors have been only partially elucidated. Phosphatases play important regulatory roles in cell metabolism, but have not previously been implicated in hyperglycemia-induced cell death. We investigated the role of the phosphatase, type 2A protein phosphatase (PP2A), in hyperglycemia-induced changes in signaling and death in bovine aortic endothelial cells (BAEC). We explored also the influence of benfotiamine on this phosphatase. Activation of PP2A was assessed in BAEC by the extent of methylation and measurement of activity, and the enzyme was inhibited using selective pharmacological (okadaic acid, sodium fostriecin) and molecular (small interfering RNA) approaches. BAECs cultured in 30 mM glucose significantly increased PP2A methylation and activity, and PP2A inhibitors blocked these abnormalities. PP2A activity was increased also in aorta and retina from diabetic rats. NF-κB activity and cell death in BAEC were significantly increased in 30 mM glucose and inhibited by PP2A inhibition. NF-κB played a role in the hyperglycemia-induced death of BAEC, since blocking its translocation with SN50 also inhibited cell death. Inhibition of PP2A blocked the hyperglycemia-induced dephosphorylation of NF-κB and Bad, thus favoring cell survival. Incubation of benfotiamine with BAEC inhibited the high glucose-induced activation of PP2A and NF-κB and cell death, as well as several other metabolic defects, which likewise were inhibited by inhibitors of PP2A. Activation of PP2A contributes to endothelial cell death in high glucose, and beneficial actions of benfotiamine are due, at least in part, to inhibition of PP2A activation.

Explore causes and timing of death from the CoreValve US Pivotal High-Risk Trial. An independent clinical events committee adjudicated causes of death, followed by post hoc hierarchical classification. Baseline characteristics, early outcomes, and causes of death were evaluated for 3 time periods (selected based on threshold of surgical 30-day mortality and on the differences in the continuous hazard between the 2 groups): early (0-30 days), recovery (31-120 days), and late (121-365 days). Differences in the rate of death were evident only during the recovery period (31-120 days), whereas 15 patients undergoing transcatheter aortic valve replacement (TAVR) (4.0%) and 27 surgical aortic valve replacement (SAVR) patients (7.9%) died (P = .025). This mortality difference was largely driven by higher rates of technical failure, surgical complications, and lack of recovery following surgery. From 0 to 30 days, the causes of death were more technical failures in the TAVR group and lack of recovery in the SAVR group. Mortality in the late period (121-365 days) in both arms was most commonly ascribed to other circumstances, comprising death from medical complications from comorbid disease. Mortality at 1 year in the CoreValve US Pivotal High-Risk Trial favored TAVR over SAVR. The major contributor was that more SAVR patients died during the recovery period (31-121 days), likely affected by the overall influence of physical stress associated with surgery. Similar rates of technical failure and complications were observed between the 2 groups. This suggests that early TAVR results can improve with technical refinements and that high-risk surgical patients will benefit from reducing complications.

Full Text Available Abstract Background Infant mortality rates (IMR remain high in many sub-Saharan African countries, especially in rural settings where access to health services may be limited. Studies in such communities can provide relevant data on the burden of and risk factors for infant death. We measured IMR and explored risk factors for infant death in a cohort of children born in Banfora Health District, a rural area in South-West Burkina Faso. Methods A prospective community-based cohort study was nested within the PROMISE-EBF trial (NCT00397150 in 24 villages of the study area. Maternal and infant baseline characteristics were collected at recruitment and after birth, respectively. Home visits were conducted at weeks 3, 6, 12, 24 and 52 after birth. Descriptive statistics were calculated using robust standard errors to account for cluster sampling. Cox multivariable regression was used to investigate potential risk factors for infant death. Results Among the 866 live born children included in the study there were 98 infant deaths, yielding an IMR of 113 per 1000 live births (95% CI: 89–143. Over 75% of infant deaths had occurred by 6 months of age and the post neonatal infant mortality rate was 67 per 1000 live births (95% CI: 51–88. Infections (35% and preterm births complications (23% were the most common probable causes of death by 6 months. Multivariable analyses identified maternal history of child death, polygyny, twin births and poor anthropometric z-scores at week-3 as factors associated with increased risk of infant death. Conclusions We observed a very high IMR in a rural area of Burkina Faso, a country where 75% of the population lives in rural settings. Community-based health interventions targeting mothers and children at high risk are urgently needed to reduce the high burden of infant deaths in these areas.

Mechanism of death at high temperatures in Helix and Patella

Energy Technology Data Exchange (ETDEWEB)

Grainger, J N.R.

1975-10-01

In Patella vulgata and Helix aspersa which had been killed by exposure to high temperatures, the rates of oxygen consumption of gill, foot muscle and hepatopancreas are remarkably steady when measured at lower temperatures, although the absolute levels are in some cases different from normal animals. These tissues are thus substantially metabolically intact in heat dead individuals. In Helix there is a fall in blood sodium and a rise in blood potassium during heat death. In Patella there is a marked rise in blood Na/sup +/ and a consequent disturbance of the Na/sup +//K/sup +/ ratio. These ionic disturbances are thought to be a prime cause of heat death. The significance of the results is discussed.

Driving under the influence (DUI) of alcohol and illicit drugs is a serious road safety concern. This research aimed to examine trends in DUI across time and changes in attitudes towards the risks (crash and legal) associated with DUI among regular ecstasy users (REU) interviewed in Australia. Participants were regular (at least monthly) ecstasy users surveyed in 2007 (n=573) or 2011 (n=429) who had driven a car in the last six months. Face to face interviews comprised questions about recent engagement of DUI and roadside breath (alcohol) and saliva (drug) testing. Participants also reported the risk of crash and of being apprehended by police if DUI of alcohol, cannabis, ecstasy, and methamphetamine. There were significant reductions in DUI of psychostimulants (ecstasy, methamphetamine, cocaine, LSD) but not alcohol or cannabis between 2007 and 2011. This was accompanied by increased experience of roadside saliva testing and increases in crash and legal risk perceptions for ecstasy and methamphetamine, but not alcohol or cannabis. When the relationship between DUI and risk variables was examined, low crash risk perceptions were associated with DUI of all substances and low legal risk perceptions were associated with DUI of ecstasy. The observed reduction in DUI of psychostimulants among frequent ecstasy consumers may be related to increased risk awareness stemming from educational campaigns and the introduction of saliva testing on Australian roads. Such countermeasures may be less effective in relation to deterring or changing attitudes towards DUI of cannabis and alcohol among this group. Copyright © 2014 Elsevier Ireland Ltd.

Driving while intoxicated or under the influence (DUI; for the purposes of this paper, we use the following terms synonymously: driving under the influence, driving while intoxicated, and drunk driving) and engaging in interpersonal violence are two injury-related problems of high public health importance that have both been linked to alcohol consumption. This study sought to estimate the prevalence of DUI and violence in a sample of individuals in treatment for alcohol dependence in Poland. Patient characteristics associated with DUI and violence involvement, with a particular focus on impulsivity, were examined. Three hundred and sixty-four patients consecutively admitted to four alcohol treatment programs in Warsaw, Poland participated in this study. Questions concerning history of interpersonal violence as well as those about DUI were derived from the Michigan Alcoholism Screening Test. Impulsivity level was measured using the Barratt Impulsiveness Scale 11, the Revised NEO Personality Inventory, and the stop-signal task. Among all participants in the study, 148 (40.1%) had been arrested in the past for DUI, and 196 (55%) reported involvement in a fight under the influence of alcohol (FUI). The DUI group had a significantly earlier onset of alcohol problems, a longer period of heavy alcohol use, and fewer women in comparison to participants without a DUI history. FUI patients were significantly younger, with a younger average age of onset of drinking problems, longer period of heavy drinking, and lower percentage of women than the non-FUI group. Both of the self-reported measures of impulsivity indicated a higher level of impulsivity among participants from the FUI group than those from the non-FUI group. © 2013 S. Karger AG, Basel.

High dietary protein diets are widely used to manage overweight and obesity. However, there is a lack of consensus about their long-term efficacy and safety. Therefore, the aim of this study was to assess the effect of long-term high-protein consumption on body weight changes and death outcomes in subjects at high cardiovascular risk. A secondary analysis of the PREDIMED trial was conducted. Dietary protein was assessed using a food-frequency questionnaire during the follow-up. Cox proportional hazard models were used to estimate the multivariate-adjusted hazard ratio (HR) and 95% confidence intervals (95%CI) for protein intake in relation to the risk of body weight and waist circumference changes, cardiovascular disease, cardiovascular death, cancer death and total death. Higher total protein intake, expressed as percentage of energy, was significantly associated with a greater risk of weight gain when protein replaced carbohydrates (HR: 1.90; 95%CI: 1.05, 3.46) but not when replaced fat (HR: 1.69; 95%CI: 0.94, 3.03). However, no association was found between protein intake and waist circumference. Contrary, higher total protein intake was associated with a greater risk of all-cause death in both carbohydrate and fat substitution models (HR: 1.59; 95%CI: 1.08, 2.35; and HR: 1.66; 95%CI: 1.13, 2.43, respectively). A higher consumption of animal protein was associated with an increased risk of fatal and non-fatal outcomes when protein substituted carbohydrates or fat. Higher dietary protein intake is associated with long-term increased risk of body weight gain and overall death in a Mediterranean population at high cardiovascular risk.

Using a survey of drinkers (N = 1,634), we evaluated alternative explanations of heavy and binge drinking, driving under the influence (DUI), DUI arrests, speeding citations, and chargeable accidents. Explanations included socializing, short-term decision-making, unrealistic optimism, risk preferring behavior, and addiction. Most consistent relationships were between substance use and alcohol addiction and dependent variables for (1) binge drinking and (2) DUI episodes. Respondent characteristics (age, marital and employment status, race, etc.) had important roles for DUI arrests. Drinker-drivers and those arrested for DUI are partially overlapping groups with implications for treatment and policies detecting and incapacitating persons from drinking and driving.

The places of death for people who died of suicide were compared across eight countries and socio-demographic factors associated with home suicide deaths identified. Death certificate data were analyzed; using multivariable binary logistic regression to determine associations. National suicide death rates ranged from 1.4 % (Mexico) to 6.4 % (South Korea). The proportion of suicide deaths occurring at home was high, ranging from 29.9 % (South Korea) to 65.8 % (Belgium). Being older, female, widowed/separated, highly educated and living in an urban area were risk factors for home suicide. Home suicide deaths need specific attention in prevention programs.

2014-07-01

Full Text Available Introduction: Conviction rates for drivers driving under the influence (DUI and in motor vehicle collisions (MVC presenting to trauma centers are based primarily on data from the 1990s. Our goal was to identify DUI conviction rates of intoxicated drivers in MVCs presenting to a trauma center and to identify factors associated with the failure to obtain a DUI conviction. Methods: Retrospective study of adults (>18 years presenting to a trauma center emergency department (ED in 2007. Eligible subjects were drivers involved in a MVC with an ED blood alcohol level (BAL ≥ 80mg/dL. Subjects were matched to their Department of Motor Vehicle (DMV records to identify DUI convictions from the collision, the legal blood alcohol concentration (BAC, and arresting officer’s impression of the driver’s sobriety. We entered potential variables predictive of failure to obtain a DUI conviction into a regression model. Results: The 241 included subjects had a mean age of 34.1 ± 12.8 years, and 185 (77% were male. Successful DUI convictions occurred in 142/241 (58.9%, 95% CI 52.4, 65.2% subjects. In a regression model, Injury Severity Score > 15 (odds ratio = 2.70 (95% CI 1.06, 6.85 and a lower ED BAL from 80 to 200mg/dL (odds ratio = 5.03 (95% CI 1.69, 14.9 were independently associated with a failure to obtain a DUI conviction. Conclusion: Slightly more than half of drivers who present to an ED after a MVC receive a DUI conviction. The most severely injured subjects and those with lower BALs are least likely to be convicted of a DUI.

Deciphering the link between doubly uniparental inheritance of mtDNA and sex determination in bivalves: Clues from comparative transcriptomics

Bivalves exhibit an astonishing diversity of sexual systems and sex-determining mechanisms. They can be gonochoric, hermaphroditic or androgenetic, with both genetic and environmental factors known to determine or influence sex. One unique sex-determining system involving the mitochondrial genome has also been hypothesized to exist in bivalves with doubly uniparental inheritance (DUI) of mtDNA. However, the link between DUI and sex determination remains obscure. In this study, we performed a comparative gonad transcriptomics analysis for two DUI-possessing freshwater mussel species to better understand the mechanisms underlying sex determination and DUI in these bivalves. We used a BLAST reciprocal analysis to identify orthologs between Venustaconcha ellipsiformis and Utterbackia peninsularis and compared our results with previously published sex-specific bivalve transcriptomes to identify conserved sex-determining genes. We also compared our data with other DUI species to identify candidate genes possibly involved in the regulation of DUI. A total of ∼12,000 orthologous relationships were found, with 2,583 genes differentially expressed in both species. Among these genes, key sex-determining factors previously reported in vertebrates and in bivalves (e.g., Sry, Dmrt1, Foxl2) were identified, suggesting that some steps of the sex-determination pathway may be deeply conserved in metazoans. Our results also support the hypothesis that a modified ubiquitination mechanism could be responsible for the retention of the paternal mtDNA in male bivalves, and revealed that DNA methylation could also be involved in the regulation of DUI. Globally, our results suggest that sets of genes associated with sex determination and DUI are similar in distantly-related DUI species.

The aim of this naturalistic study was to evaluate the potential influence of the duration of untreated illness (DUI)--defined as the time elapsed between the occurrence of the first mood episode and the first adequate pharmacological treatment with mood stabilizers--on the clinical course of bipolar disorder (BD). Three hundred and twenty outpatients (n = 320) with a DSM-IV diagnosis of BD--either Type I or Type II--were interviewed; their clinical features were collected and they were naturalistically followed-up for 5 years. At the end of the follow-up observation, the sample was subdivided into two groups: one group with a DUI 2 years (n = 255). The main demographic and clinical variables were analyzed and compared between the two subgroups of patients using chi-square tests for dichotomous variables or Mann-Whitney U tests for continuous variables. Patients with a longer DUI showed a higher frequency of suicide attempts (Z = -2.11, P = 0.035), a higher number of suicide attempters (chi(2) = 4.13, df = 1, P = 0.04), and a longer duration of illness (Z = -6.79, P < 0.0001) when compared to patients with a shorter DUI. Moreover, patients with a longer DUI had a depressive first episode more frequently than patients with a shorter DUI (chi(2) = 11.28, df = 2, P = 0.004). A further analysis performed dividing the total sample into two subgroups on the basis of a DUI of 6 years (corresponding to the median value of the DUI in the study sample) confirmed prior findings. Results indicate a potential association between a longer DUI and a worse outcome in BD, particularly in terms of suicidality, and confirm the clinical relevance of early diagnosis and pharmacological intervention with mood stabilizers in BD.

Full Text Available High glucose-induced cardiomyocyte death is a common symptom in advanced-stage diabetic patients, while its metabolic mechanism is still poorly understood. The aim of this study was to explore metabolic changes in high glucose-induced cardiomyocytes and the heart of streptozotocin-induced diabetic rats by 1H-NMR-based metabolomics. We found that high glucose can promote cardiomyocyte death both in vitro and in vivo studies. Metabolomic results show that several metabolites exhibited inconsistent variations in vitro and in vivo. However, we also identified a series of common metabolic changes, including increases in branched-chain amino acids (BCAAs: leucine, isoleucine and valine as well as decreases in aspartate and creatine under high glucose condition. Moreover, a reduced energy metabolism could also be a common metabolic characteristic, as indicated by decreases in ATP in vitro as well as AMP, fumarate and succinate in vivo. Therefore, this study reveals that a decrease in energy metabolism and an increase in BCAAs metabolism could be implicated in high glucose-induced cardiomyocyte death.

Full Text Available There is only one exception to strict maternal inheritance of mitochondrial DNA (mtDNA in the animal kingdom: a system named doubly uniparental inheritance (DUI, which is found in several bivalve species. Why and how such a radically different system of mitochondrial transmission evolved in bivalve remains obscure. Obtaining a more complete taxonomic distribution of DUI in the Bivalvia may help to better understand its origin and function. In this study we provide evidence for the presence of sex-linked heteroplasmy (thus the possible presence of DUI in two bivalve species, i.e., the nuculanoid Yoldia hyperborea(Gould, 1841and the veneroid Scrobicularia plana(Da Costa,1778, increasing the number of families in which DUI has been found by two. An update on the taxonomic distribution of DUI in the Bivalvia is also presented.

Full text: This study was conducted to investigate the mode(s) of cell death induced by high radiation doses in the highly radioresistant Sf9 insect ovarian cell line. Methods: Cells were exposed to γ-radiation doses 200Gy and 500Gy, harvested at various time intervals (6h-72h) following irradiation, and subjected to cell morphology assay, DNA agarose gel electrophoresis, single cell gel electrophoresis (SCGE; comet assay) and Annexin-V labeling for the detection of membrane phosphatidylserine externalization. Cell morphology was assessed in cells entrapped and fixed in agarose gel directly from the cell suspension, thus preventing the possible loss of fragments/ apoptotic bodies. Surviving fraction of Sf9 cells was 0.01 at 200Gy and 98%) undergoing extensive DNA fragmentation at 500Gy, whereas the frequency of cells with DNA fragmentation was considerably less (∼12%) at 200Gy. Conclusions: While the mode of cell death at 200Gy seems to be different from typical apoptosis, a dose of 500Gy induced bimodal cell death, with typical apoptotic as well as the atypical cell death observed at 200Gy

Diabetic retinopathy (DR) is the most common complication of diabetes and remains one of the major causes of blindness in the world; infants born to diabetic mothers have higher risk of developing retinopathy of prematurity (ROP). While hyperglycemia is a major risk factor, the molecular and cellular mechanisms underlying DR and diabetic ROP are poorly understood. To explore the consequences of retinal cells under high glucose, we cultured wild type or E2f1 -/- mouse retinal explants from postnatal day 8 with normal glucose, high osmotic or high glucose media. Explants were also incubated with cobalt chloride (CoCl 2 ) to mimic the hypoxic condition. We showed that, at 7 days post exposure to high glucose, retinal explants displayed elevated cell death, ectopic cell division and intact retinal vascular plexus. Cell death mainly occurred in excitatory neurons, such as ganglion and bipolar cells, which were also ectopically dividing. Many Müller glial cells reentered the cell cycle; some had irregular morphology or migrated to other layers. High glucose inhibited the hyperoxia-induced blood vessel regression of retinal explants. Moreover, inactivation of E2f1 rescued high glucose-induced ectopic division and cell death of retinal neurons, but not ectopic cell division of Müller glial cells and vascular phenotypes. This suggests that high glucose has direct but distinct effects on retinal neurons, glial cells and blood vessels, and that E2f1 mediates its effects on retinal neurons. These findings shed new light onto mechanisms of DR and the fetal retinal abnormalities associated with maternal diabetes, and suggest possible new therapeutic strategies.

According to anxiety buffer disruption theory (ABDT), people function effectively in the world, in part, by relying on anxiety-buffer systems to protect against death awareness; however, traumatic experiences can overwhelm and disrupt those anxiety-buffer systems, leaving people unprotected from death awareness and at increased risk for the major symptom clusters of posttraumatic stress disorder (PTSD). Based on that idea, it was hypothesized that (a) when posttraumatic stress symptoms are low, self-affirmation (a known worldview/self-esteem based anxiety-buffer) should prevent mortality reminders from causing increased death-thought accessibility (DTA); but that (b) when posttraumatic stress symptoms are high (indicating anxiety-buffer disruption), self-affirmation should fail to prevent mortality reminders from increasing DTA. To test these hypotheses, participants identified in a general population prescreen assessment as "low posttraumatic-stress symptom" (n = 222) and "high posttraumatic-stress symptom" (n = 210) were reminded of death (vs. control topic), prompted to engage in a self-affirmation (vs. nonself-affirmation) task, and then asked to complete a standard assessment of death-thought accessibility (DTA). The hypotheses were confirmed, revealing that posttraumatic stress symptoms were associated with the ineffectiveness of anxiety-buffer system in protecting against increased death awareness. The present findings support of a foundational concept of ABDT, and point to new insights about the nature of PTSD and its treatment, because failure to manage death awareness is known to cause anxiety and exacerbate anxiety-related disorders (e.g., PTSD).

Full Text Available This study describes the psychological effects of an experience of death education (DE used to explore a case of suicide in an Italian high school. DE activities included philosophical and religious perspectives of the relationships between death and the meaning of life, a visit to a local hospice, and psychodrama activities, which culminated in the production of short movies. The intervention involved 268 high school students (138 in the experimental group. Pre-test and post-test measures assessed ontological representations of death, death anxiety, alexithymia, and meaning in life. Results confirmed that, in the experimental group, death anxiety was significantly reduced as much as the representation of death as annihilation and alexithymia, while a sense of spirituality and the meaning of life were more enhanced, compared to the No DE group. These improvements in the positive meaning of life and the reduction of anxiety confirmed that it is possible to manage trauma and grief at school with death education interventions that include religious discussion, psychodrama and movie making activities.

The purpose of the present study was to identify characteristics of visiting nurse agencies (VNA) in Japan with high home death rates by a prefecture-wide survey. A cross-sectional study of visiting nurse agencies (n = 101) in Ibaraki Prefecture, Japan, was completed. Data included the basic characteristics of each VNA, the type of services provided, level of coordination with other service providers, total number of VNA patients who died per year and place of death and contractual relationship with home-care supporting clinics providing end-of-life care services in the home 24 h a day. The VNA characteristics were analyzed by logistic regression, using the home death rate per VNA as a dependent variable. A total 69 agencies, excluding those that did not report number of deaths (n = 14) and those without deaths during the year (n = 6), were analyzed. The median home death rate of the 69 VNA was 29.8%. The results of logistic regression analysis showed that higher home death rate was significantly associated with lack of attachment to a hospital, existence of a contractual relationship with home-care supporting clinics and existence of an interactive information exchange through telephone/face-to-face communication with attending physicians. In order to increase the home death rate of people using VNA, policymakers must consider establishing home-based service systems within the community that can provide home end-of-life care services 24 h a day, and support the interactive exchange of information between the visiting nurse and the attending physician. © 2014 The Authors.

Risk, control and self-identity: Young drunk drivers’ experiences with driving under the influence of alcohol and drugs

Directory of Open Access Journals (Sweden)

Fynbo Lars

2014-06-01

Full Text Available AIM - This article explores how young Danish drunk (and drug drivers relate to the risk of driving under the influence (DUI. DESIGN - The study is based on qualitative interviews with 25 convicted drunk drivers who in 2010 participated in mandatory alcohol and traffic safety courses. The analysis follows Stephen Lyng’s concept of “edgework”, focusing on volitional risk taking and its effect on the acting individual’s self-identity. RESULTS - Drawing on the interviewees’ accounts of being arrested for drunk driving, the analysis discusses three different categories of young drunk drivers. Those in the first category view a DUI arrest as a loss of control and a reminder of the risk of DUI. Those in the second present DUI as a reaction to what they perceive as untenable social demands. Those in the third see loss of control - such as causing a traffic accident - as the ultimate way of claiming control over their lives. CONCLUSION - The study shows that young drunk drivers have different associations with DUI-related risks. The more constrained they feel in relation to society, the more likely it is that they will divorce negative experiences related to DUI such as being arrested or causing a traffic accident.

To identify lipidemic, hemostasiological, and hemodynamic indicators associated with the risk of cardiovascular death in high- and very high-risk patients. One hundred and forty-eight patients whose mean age was 50.8 +/- 4.4 years were examined. All the patients were divided into high (1 group) and very high (2 group) cardiovascular death risk groups according to the SCORE scale. Lipid metabolism, hemostatic system parameters (fibrinogen, time of ADP-induced platelet aggregation initiation, D-dimer), endothelial dysfunction markers (von Willebrand factor), and echocardiographic findings were studied. Multivariate regression analysis showed that the odds ratio for a cardiovascular death risk was 1.8 (95% confidence interval (CI), 1.1 to 4.2; p = 0.04) in patients with a D-dimer level of greater than 1 mg/ml, 0.77 (95% CI, 0.6 to 0.97; p = 0.03) in those with an ADP-induced platelet aggregation initiation time of 13.5 sec, 1.04 (95% CI, 1.01 to 1.07; p = 0.02) in those with an end-diastolic volume of more than 123 ml, 1.1 (95% CI, 1.04 to 1.2; p = 0.003) in those with an end-diastolic dimension of more than 51 mm, 1.5 (95% CI, 1.1 to 2.0; p = 0.009) in those with a ventricular septal thickness of more than 11.5 mm, and 2.1 (95% CI, 1.03 to 3.2; p = 0.0032) in those with avon Willebrand factor level of more than 140%. The high levels of von Willebrand factor, D-dimer, ADP-induced platelet aggregation, triglycerides, end-diastolic volume, end-diastolic dimension, and ventricular septal thickness are independent predictors of cardiovascular death in very high-risk patients. These indicators bear out a close relationship between lipid metabolic and hemostatic disturbances and between endothelial dysfunction and intracardiac hemodynamic worsening in these patients.

Alcohol use has been previously associated with neurocognitive impairments, especially in decision-making cognition. However, some studies have shown little to no decision-making deficits in relation to different characteristics of people with drinking problems. Relapsing to driving under the influence (DUI) of alcohol is an important issue with legal and psychosocial aspects. We evaluated decision-making performance in second-time DUI offenders by using the Iowa Gambling Task (IGT). Thirty-four male second-time DUI offenders who had been selected for an official psychoeducational rehabilitation program and 31 healthy controls that were matched for age, education, and alcohol use were included. Along with psychiatric assessment, we applied conventional neuropsychological testing comprising cognitive set-shifting, response inhibition, attention, and visuospatial abilities. Also, we used the Temperament and Character Inventory (TCI) to assess personality patterns. A computerized version of IGT was used. No significant differences were found between the groups in regard to sociodemographics and conventional neuropsychological testing. DUI participants had significantly higher scores only in "self-transcendence" subdomain of TCI. On the fifth block of the IGT, DUI participants had significantly lower net scores than controls (U = 380.0, p decision-making deficits in DUI participants, which goes undetected on conventional neuropsychological testing and which is not correlated with TCI subdomains related with impulsivity patterns.

Purpose: To evaluate the primary causes of death in low-risk (low-risk), intermediate-risk (intermediate-risk), and high-risk (high-risk) patients undergoing permanent prostate brachytherapy with or without supplemental therapies. Methods and Materials: From April 1995 through November 2004, a total of 1,354 consecutive patients underwent prostate brachytherapy. All patients underwent brachytherapy >3 years before analysis. Of the patients, 532 (39.3%) received androgen deprivation therapy and 703 (51.9%) received supplemental radiation therapy. The median follow-up was 5.4 years. Multiple parameters were evaluated as predictors of cause-specific, biochemical progression-free, and overall survival. Results: The 10-year cause-specific survival was 97.0% (99.7%, 99.0%, and 90.1% for low-risk, intermediate-risk, and high-risk patients). Overall survival was 76.7% (82.5%, 78.3%, and 67.6% for low-, intermediate-, and high-risk patients, respectively). The cumulative death rate for cardiovascular disease was 11.5% (8.7%, 9.3%, and 19.8% for low-, intermediate-, and high-risk patients). The death rate from second malignancies (nonprostate cancer) was 7.2% and was not substantially different when stratified by risk group. Death from all other causes was 6.5% for the entire cohort but 1.3%, 5.0%, and 10.8% for low-, intermediate-, and high-risk patients. In multivariate analysis, death from prostate cancer was best predicted by Gleason score and risk group, whereas death from cardiovascular disease, nonprostate cancer, and all other causes were most closely related to patient age and tobacco use. Conclusions: Although cardiovascular mortality was the predominant cause of death, prostate cancer was responsible for approximately 10% of all deaths. In particular, overall survival was poorest in the high-risk group. Although high-risk patients were most likely to die of prostate cancer, the divergence in overall survival between high-risk and lower-risk patients primarily

The latency to first pharmacological treatment (duration of untreated illness or 'DUI') is supposed to play a major role in terms of outcome in psychotic conditions. Interest in the field of affective disorders and, in particular, of duration of untreated anxiety, has been recently registered as well. However, a preliminary epidemiologic investigation of the phenomenon is necessary. The present study was aimed to investigate and compare age at onset, age at first pharmacological treatment and DUI in a sample of patients affected by different anxiety disorders. DUI was defined as the interval between the onset of the specific anxiety disorder and the administration of the first adequate pharmacological treatment in compliant subjects. Study sample included 350 patients, of both sexes, with a DSM-IV-TR diagnosis of panic disorder (n = 138), generalized anxiety disorder (n = 127) and obsessive-compulsive disorder (n = 85). Panic disorder was associated with the shortest DUI (39.5 months), whereas obsessive-compulsive disorder was associated with the longest latency to treatment (94.5 months) (F = 13.333; P anxiety disorder showed a mean DUI of 81.6 months. Present results indicate that patients with different anxiety disorders may wait for years (from 3 up to 8) before receiving a first adequate pharmacological treatment. Differences in terms of age at onset, age at the first pharmacological treatment and, ultimately, in DUI in specific anxiety disorders may depend on multiple clinical and environmental factors. Latency to non-pharmacological interventions (e.g. psychoeducation and different forms of psychotherapy) needs to be addressed and correlated with DUI in future studies. © 2013 Wiley Publishing Asia Pty Ltd.

This paper presents the results of a case-control study of deaths from liver, stomach and lung cancers in the high background radiation areas (HBRA) in Yangjiang County and neighboring control areas (CA). The purpose of this study was to explore the probable relationship between the cancer deaths and the environmental mutation-related factors in the two areas, so that the role of elevated natural radiation in cancer mortality could be properly ascertained. The studied numbers of cases of liver, stomach and lung cancers were 64, 28 and 17 in HBRA, and 75, 36 and 13 in CA, respectively. The proportion of the number of cases to that of the controls was 1:1 for liver cancer and 1:2 for cancers of stomach and lung. The factors studied included pesticide, smoking, alcohol consumption, medical X-ray exposure, diet, and the socioeconomic status, such as occupation, education, economic income, living space etc. The data for this study were collected through interviewing. The data collected were analysed by methods of matched and unmatched studies. The results expressed by odds ratio (OR) show that there is no significant between most factors studied and cancer deaths, although the associations of desths from stomach cancer with drinking water of nonwell source and of lung cancer with alcohol consumption in HBRA, and the associations of liver cancer deaths with occupations involving poisonous and noxious substances, pesticide and alcohol, and of lung cancer with pesticide and lower family income in CA can be found. This study has provided some clues for explaining the difference in cancer mortalities between HBRA and CA

Nowadays traffic accidents, which have high mortality and morbidity, are an important public health problem. The association between the use of alcohol and/or drugs by drivers and the increased risk of traffic accidents with a high risk of death and injury has been well described in the literature. This study aimed to review the incidence of cases of driving under the influence of drugs (DUID) among all cases of driving under the influence (DUI) of alcohol and/or other drugs involved in traffic accidents and to evaluate the type of the psychoactive drugs (with or without alcohol) detected in blood samples in Istanbul and its surrounding area. This study is the first investigation on the subject of DUID cases in Turkey. The reports of the Istanbul Toxicology Department of the Council of Forensic Medicine (Turkey) on suspected DUID cases involved in traffic accidents between 1 July 2010 and 30 June 2011 were retrospectively reviewed for alcohol and/or drug use. Alcohol analysis was requested in 4274 suspected DUI cases, whereas drug along with alcohol analysis was requested in only 91. The rate of suspected DUID cases (n = 91) among the suspected DUI cases (n = 4274) was only 2.1% and in this study, we evaluated only the DUID cases in detail. Alcohol was present in 44% of suspected DUID cases. Psychoactive drugs were present in 15.4% of cases. The incidence among 46 confirmed DUID cases was found to be 17.4% for cannabis, 8.7% for benzodiazepines, 4.3% for barbiturates, 4.3% for antidepressants, 2.2% for cocaine and 2.2% for amphetamines. Although there is a zero-tolerance approach for DUID in the Turkish regulations, it is not well recognised and not inspected by police and legal authorities who are responsible for taking measures in traffic accidents and for routine traffic controls in Turkey. It is concluded that psychoactive drugs should be checked as well as alcohol in all traffic accident cases and roadside controls. Copyright © 2013 Elsevier Ltd and Faculty

Staging Death, Translating Death, Rehearsing Death: A Photographer’s Apprenticeship in Dying

Directory of Open Access Journals (Sweden)

Daniela Fargione

2010-10-01

Full Text Available The preponderance of death imagery in the mass media and a recent interest of photography in the practice of death suggest the need to reevaluate our approach to death and dying, especially when violence is involved. This essay is a case study of History of Violence, Claudio Cravero's last photographic project. His collection of "portraits" reproduce apparent dead bodies, mostly attacked in their own domestic spheres, but neither the perpetrator of death (a mysterious murderer?, nor the weapon used (an omnipresent knife, should be considered as main focal points of the artist's inquiry. The undoubtful protagonist of these photographs, instead, is the light, that illuminates fear: not of death itself, rather of the obnoxious indifference to it, as the result of generalized death imagery saturation.     The staged apparent death displayed in Cravero's photographs serve both as a memento mori and as a strategy to come to terms with the idea of death. In short, it is an apprentship in dying through a domesticating translation practice. Eventually, Cravero's History of Violence offers a complex reflection on the interplay between each individual story and macrolevel social History, thus providing some hypotheses of where violence and death fit in that odd geometry of time and space that we call life.

Williams Syndrome (WS) is a microdeletion syndrome (chromosome 7q11.23) characterized by typical facial features, cardiovascular disease, behavioural symptoms, and mild intellectual disability (ID). The aim of this study was to assess the rates of incontinence and psychological problems in persons with WS. 231 individuals with WS were recruited through the German parent support group (52.0% male, mean age 19.4 years). Faecal incontinence (FI) was diagnosed from the age of 4 years and nocturnal enuresis (NE) and daytime urinary incontinence (DUI) of 5 years onwards. The Parental Questionnaire: Enuresis/Urinary Incontinence, the International-Consultation-on-Incontinence-Questionnaire-Pediatric LUTS (ICIQ-CLUTS), as well as the Developmental Behavior Checklist for parents (DBC-P) or for adults (DBC-A) were filled out by parents or caregivers. 17.8% of the sample had NE, 5.9% DUI and 7.6% FI. NE was present in 44.9% of children (4-12 years), 13.5% of teens (13-17y), 3.3% of young adults (18-30y) and in 3.6% of adults (> 30y). DUI (and FI) decreased from 17.9% (21.4%) in children to 0% in adults. 3.5% of the sample had an ICIQ-CLUTS score in the clinical range. 30.5% of children and 22.1% of adults had a clinical DBC score. Children and teens with clinically relevant DBC-P-scores had significantly higher DUI rates. Children with WS have high rates of incontinence and LUTS, which decrease with age. Most adults are continent. NE is the most common subtype. Except for DUI in children, incontinence is not associated with behavioural problems. Screening, assessment and treatment of incontinence in individuals with WS is recommended. Neurourol. Urodynam. 35:1000-1005, 2016. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

To identify the factors associated with intra-hospital neonatal mortality based on the individual characteristics of at-risk pregnant mothers, delivery and newborns. This was a cross-sectional epidemiological study of live newborns delivered by women attended at the high-risk outpatient unit of a philanthropic hospital in Maringá, Paraná, Brazil between September 2012 and September 2013. Six hundred and eighty-eight women participated in the study. The neonatal mortality coefficient found was 17.7/1,000 live births, most in the early neonatal phase. Premature labor, fetal malformation and multiple gestations were associated with neonatal death. Premature, very low birth weight newborns and those with an Apgar score of less than seven, five minutes after birth were at high risk of death. Identifying risk factors can help plan actions to consolidate the perinatal network. Specific programs should be incentivized in other countries, in the search for significant perinatal results such as reducing neonatal mortality. Identificar os fatores associados à mortalidade neonatal intra-hospitalar com base nas características individuais de gestantes de risco, do parto e do recém-nascido. Estudo epidemiológico do tipo transversal, realizado com crianças nascidas vivas de partos hospitalares de mulheres acompanhadas pelo ambulatório de alto risco de um hospital filantrópico de Maringá, Paraná, Brasil, no período de setembro de 2012 a setembro de 2013.RESULTADOS Fizeram parte da pesquisa 688 mulheres. O coeficiente de mortalidade neonatal foi de 17,7 óbitos/1.000 nascidos vivos, sendo sua maioria no período neonatal precoce. Trabalho de parto prematuro, malformação fetal e gestação múltipla foram as intercorrências associadas ao óbito neonatal. Recém-nascidos prematuros, com muito baixo peso ao nascer e Índice de Apgar menor que sete no quinto minuto de vida apresentaram risco elevado de morte.

Doubly uniparental inheritance of mitochondria as a model system for studying germ line formation.

Directory of Open Access Journals (Sweden)

Liliana Milani

Full Text Available BACKGROUND: Doubly Uniparental Inheritance (DUI of mitochondria occurs when both mothers and fathers are capable of transmitting mitochondria to their offspring, in contrast to the typical Strictly Maternal Inheritance (SMI. DUI was found in some bivalve molluscs, in which two mitochondrial genomes are inherited, one through eggs, the other through sperm. During male embryo development, spermatozoon mitochondria aggregate in proximity of the first cleavage furrow and end up in the primordial germ cells, while they are dispersed in female embryos. METHODOLOGY/PRINCIPAL FINDINGS: We used MitoTracker, microtubule staining and transmission electron microscopy to examine the mechanisms of this unusual distribution of sperm mitochondria in the DUI species Ruditapes philippinarum. Our results suggest that in male embryos the midbody deriving from the mitotic spindle of the first division concurs in positioning the aggregate of sperm mitochondria. Furthermore, an immunocytochemical analysis showed that the germ line determinant Vasa segregates close to the first cleavage furrow. CONCLUSIONS/SIGNIFICANCE: In DUI male embryos, spermatozoon mitochondria aggregate in a stable area on the animal-vegetal axis: in organisms with spiral segmentation this zone is not involved in cleavage, so the aggregation is maintained. Moreover, sperm mitochondria reach the same embryonic area in which also germ plasm is transferred. In 2-blastomere embryos, the segregation of sperm mitochondria in the same region with Vasa suggests their contribution in male germ line formation. In DUI male embryos, M-type mitochondria must be recognized by egg factors to be actively transferred in the germ line, where they become dominant replacing the Balbiani body mitochondria. The typical features of germ line assembly point to a common biological mechanism shared by DUI and SMI organisms. Although the molecular dynamics of the segregation of sperm mitochondria in DUI species are unknown

In-Game Health Communication: Delivering Low-Fear Health Messages in a Low-Fear Videogame.

Prior research has demonstrated that psychological immersion (or "transportation") into virtual gaming worlds can heighten influence from health-promotion messages embedded in the backgrounds of gaming scenes. However, research to date has only studied the effectiveness of embedding graphic, fear-based messages in the background of violent, first-person videogames. This study sought to examine whether transportation into a nonviolent videogame can heighten persuasion from low-fear, nongraphic health messages. Willingness to drive under the influence of alcohol (DUI) was measured in an undergraduate sample (M AGE  = 19) at the start of the semester, and n = 220 returned 0-3 months later to play a car-racing videogame. All were randomly assigned to play either a version of the game containing background billboards that delivered simple, text-based anti-DUI messages or consumer advertising. Self-reported levels of transportation were assessed, as well as postgame willingness to DUI. Exposure to anti-DUI messages from within the game predicted lower postgame willingness to DUI. Moreover, replicating prior research, the effect of message exposure was largest among those who reported higher levels of pregame willingness to DUI, and higher levels of in-game transportation. This study replicates prior research by suggesting that immersive videogames that promote transportation can be used to effectively deliver health communications. Results also expand prior research by providing the first evidence that such effects can generalize when health messaging orients around nongraphic, lower fear messages embedded within immersive but lower fear videogames.

We propose and demonstrate a sensitive diagnostic device based on an Organic Electrochemical Transistor (OECT) for direct in-vitro monitoring cell death. The system efficiently monitors cell death dynamics, being able to detect signals related to specific death mechanisms, namely necrosis or early/late apoptosis, demonstrating a reproducible correlation between the OECT electrical response and the trends of standard cell death assays. The innovative design of the Twell-OECT system has been modeled to better correlate electrical signals with cell death dynamics. To qualify the device, we used a human lung adenocarcinoma cell line (A549) that was cultivated on the micro-porous membrane of a Transwell (Twell) support, and exposed to the anticancer drug doxorubicin. Time-dependent and dose-dependent dynamics of A549 cells exposed to doxorubicin are evaluated by monitoring cell death upon exposure to a range of doses and times that fully covers the protocols used in cancer treatment. The demonstrated ability to directly monitor cell stress and death dynamics upon drug exposure using simple electronic devices and, possibly, achieving selectivity to different cell dynamics is of great interest for several application fields, including toxicology, pharmacology, and therapeutics.

A United States industry-specific gap analysis survey of the death care sector-which comprises organizations and businesses affiliated with the funeral industry and the handling of human remains- was developed, the results analyzed, and training and education needs in relation to highly infectious disease mitigation and management were explored in an effort to identify where occupational health and safety can be enhanced in this worker population. Collaborating national death care organizations distributed the 47-question electronic survey. N = 424 surveys were initiated and results recorded. The survey collected death care sector-specific information pertaining to the comfortability and willingness to handle highly infectious remains; perceptions of readiness, current policies and procedures in place to address highly infectious diseases; current highly infectious disease training levels, available resources, and personal protective equipment. One-third of respondents have been trained on how to manage highly infectious remains. There was a discrepancy between Supervisor/Management and Employee/Worker perceptions on employees' willingness and comfortability to manage potentially highly infectious remains. More than 40% of respondents did not know the correct routes of transmission for viral hemorrhagic fevers. Results suggest death care workers could benefit from increasing up-to-date industry-specific training and education on highly infectious disease risk mitigation and management. Professional death care sector organizations are positioned to disseminate information, training, and best practices.

[Maternal death: unequal risks].

Nearly 99% of maternal deaths in the world each year occur in developing countries. New efforts have recently been undertaken to combat maternal mortality through research and action. The medical causes of such deaths are coming to be better understood, but the social mechanisms remain poorly grasped. Maternal mortality rates in developing countries are difficult to interpret because they tend to exclude all deaths not occurring in health care facilities. The countries of Europe and North America have an average maternal mortality rate of 30/100,000 live births, representing about 6000 deaths each year. The developing countries of Asia, Africa, and Latin America have rates of 270-640/100,000, representing some 492,000 deaths annually. For a true comparison of the risks of maternal mortality in different countries, the risk itself and the average number of children per woman must both be considered. A Nigerian woman has 375 times greater risk of maternal death than a Swedish woman, but since she has about 4 times more children, her lifetime risk of maternal death is over 1500 times greater than that of the Swedish woman. The principal medical causes of maternal death are known: hemorrhages due to placenta previa or retroplacental hematoma, mechanical dystocias responsible for uterine rupture, toxemia with eclampsia, septicemia, and malaria. The exact weight of abortion in maternal mortality is not known but is probably large. The possible measures for improving such rates are of 3 types: control of fertility to avoid early, late, or closely spaced pregnancies; effective medical surveillance of the pregnancy to reduce the risk of malaria, toxemia, and hemorrhage, and delivery in an obstetrical facility, especially for high-risk pregnancies. Differential access to high quality health care explains much of the difference between mortality rates in urban and rural, wealthy and impoverished areas of the same country.

Full Text Available In this study we characterized the relationship between temperature and mortality in central Arizona desert cities that have an extremely hot climate. Relationships between daily maximum apparent temperature (ATmax and mortality for eight condition-specific causes and all-cause deaths were modeled for all residents and separately for males and females ages <65 and ≥65 during the months May–October for years 2000–2008. The most robust relationship was between ATmax on day of death and mortality from direct exposure to high environmental heat. For this condition-specific cause of death, the heat thresholds in all gender and age groups (ATmax = 90–97 °F; 32.2‒36.1 °C were below local median seasonal temperatures in the study period (ATmax = 99.5 °F; 37.5 °C. Heat threshold was defined as ATmax at which the mortality ratio begins an exponential upward trend. Thresholds were identified in younger and older females for cardiac disease/stroke mortality (ATmax = 106 and 108 °F; 41.1 and 42.2 °C with a one-day lag. Thresholds were also identified for mortality from respiratory diseases in older people (ATmax = 109 °F; 42.8 °C and for all-cause mortality in females (ATmax = 107 °F; 41.7 °C and males <65 years (ATmax = 102 °F; 38.9 °C. Heat-related mortality in a region that has already made some adaptations to predictable periods of extremely high temperatures suggests that more extensive and targeted heat-adaptation plans for climate change are needed in cities worldwide.

In Brazil, underreporting of mesothelioma and cancer of the pleura (MCP) is suspected to be high. Records from death certificates (SIM) and hospital registers (SIH-SUS) can be combined to recover missing data but only anonymous databases are available. This study shows how common data can be used for linkage and as an assessment of accuracy. Mesothelioma (all sites, ICD-10 codes C45.0-C45.9) and cancer of the pleura (C38.4) were retrieved from both information systems and combined using a linkage algorithm. Accuracy was examined with non-anonymous databases, limited to the state of São Paulo. We found 775 cases in death certificates and 283 in hospital registers. The linkage matched 57 cases, all accurately paired. Three cases, 0.4% in SIM and 1.3% in SIH-SUS, could not be matched because of data inconsistencies. A computer linkage can recover MCP cases from hospital records not found in death certificates in Brazil. © 2018 Wiley Periodicals, Inc.

In 2000, the overall rate of injury deaths in children aged 0-14 was 28.7 per 100000 in Estonia, which is more than 5 times higher than the corresponding rate in neighbouring Finland. This paper describes childhood injury mortality in Estonia by cause and age groups, and validates registration of these deaths in the Statistical Office of Estonia against the autopsy data. The data on causes of all child deaths in Estonia in 2001-2005 were abstracted from the autopsy protocols at the Estonian Bureau of Forensic Medicine. Average annual mortality rates per 100,000 were calculated. Coverage (proportion of the reported injury deaths from the total number of injury deaths) and accuracy (proportion of correctly classified injury deaths) of the registration of causes of death in Statistical Office of Estonia were assessed by comparing the Statistical Office of Estonia data with the data from Estonian Bureau of Forensic Medicine. Average annual mortality from external causes in 0-14 years-old children in Estonia was 19.1 per 100,000. Asphyxia and transport accidents were the major killers followed by poisoning and suicides. Relative contribution of these causes varied greatly between age groups. Intent of death was unknown for more than 10% of injury deaths. Coverage and accuracy of registration of injury deaths by Statistical Office of Estonia were 91.5% and 95.3%, respectively. Childhood mortality from injuries in Estonia is among the highest in the EU. The number of injury deaths in Statistical Office of Estonia is slightly underestimated mostly due to misclassification for deaths from diseases. Accuracy of the Statistical Office of Estonia data was high with some underestimation of intentional deaths. Moreover, high proportion of death with unknown intent suggests underestimation of intentional deaths. Reduction of injury deaths should be given a high priority in Estonia. More information on circumstances around death is needed to enable establishing the intent of death.

Little is known about the specific causes of neonatal and under-five childhood death in high-mortality geographic regions due to a lack of primary data and dependence on inaccurate tools, such as verbal autopsy. To meet the ambitious new Sustainable Development Goal 3.2 to eliminate preventable child mortality in every country, better approaches are needed to precisely determine specific causes of death so that prevention and treatment interventions can be strengthened and focused. Minimally invasive tissue sampling (MITS) is a technique that uses needle-based postmortem sampling, followed by advanced histopathology and microbiology to definitely determine cause of death. The Bill & Melinda Gates Foundation is supporting a new surveillance system called the Child Health and Mortality Prevention Surveillance network, which will determine cause of death using MITS in combination with other information, and yield cause-specific population-based mortality rates, eventually in up to 12-15 sites in sub-Saharan Africa and south Asia. However, the Gates Foundation funding alone is not enough. We call on governments, other funders, and international stakeholders to expand the use of pathology-based cause of death determination to provide the information needed to end preventable childhood mortality.

The time period during which patients manifest psychotic or unspecific symptoms prior to treatment (duration of untreated psychosis, DUP, and the duration of untreated illness, DUI) has been found to be moderately associated with poor clinical and social outcome. Equivocal evidence exists of an association between DUP/DUI and structural brain abnormalities, such as reduced hippocampus volume (HV), pituitary volume (PV) and grey matter volume (GMV). Thus, the goal of the present work was to examine if DUP and DUI are associated with abnormalities in HV, PV and GMV. Using a region of interest (ROI) based approach, we present data of 39 patients from the Basel FePsy (Früherkennung von Psychosen, early detection of psychosis) study for which information about DUP, DUI and HV, PV and GMV data could be obtained. Twenty-three of them were first episode psychosis (FEP) and 16 at-risk mental state (ARMS) patients who later made the transition to frank psychosis. In unadjusted analyses, we found a significant positive correlation between DUP and PV in FEP patients. However, when adjusted for covariates, we found no significant correlation between DUP or DUI and HV, PV or GMV anymore. There only was a trend for decreasing GMV with increasing DUI in FEP. Our results do not comprehensively support the hypothesis of a "toxic" effect of the pathogenic mechanism underlying untreated psychosis on brain structure. If there is any effect, it might rather occur very early in the disease process, during which patients experience only unspecific symptoms. Copyright © 2017. Published by Elsevier B.V.

Postoperative ischaemia, infarction and sudden cardiac death may be triggered by episodic or constant arterial hypoxaemia, which increases during the night...... deaths occurred at night-time. These results suggest a need for further studies of sleep- and respiration-related effects on postoperative nocturnal cardiac function.

Exploration of 'over kill effect' of high-LET Ar- and Fe-ions by evaluating the fraction of non-hit cell and interphase death

The reason why relative biological effectiveness (RBE) for cell killing fell to less than unity (1.0) with very high-linear energy transfer (LET) heavy-ions ( 40 Ar: 1,640 keV/μm; 56 Fe: 780, 1,200, 2,000 keV/μm) was explored by evaluating the fraction of non-hit cell (time-lapse observation) and cells undergoing interphase death (calculation based on our previous data). Chinese hamster ovary (CHO) cells were exposed to 4 Gy (30% survival dose) of Ar (1,640 keV/μm) or Fe-ions (2,000 keV/μm). About 20% of all cells were judged to be non-hit, and about 10% cells survived radiation damage. About 70% cells died after dividing at least once (reproductive death) or without dividing (interphase death). RBE for reproductive (RBE[R]) and interphase (RBE[I]) death showed a similar LET dependence with maximum around 200 keV/μm. In this LET region, at 30% survival level, about 10% non-survivors underwent interphase death. The corresponding value for very high-LET Fe-ions (2,000 keV/μm) was not particularly high (-15%), whereas that for X-rays was less than 3%. However, reproductive death (67%) predominated over interphase death (33%) even in regard to rather severely damaged cells (1% survival level) after exposure to Fe-ions (2,000 keV/μm). These indicate that interphase death is a type of cell death characteristic for the cells exposed to high-LET radiation and is not caused by 'cellular over kill effect'. Both NHF37 (non-hit fraction at 37% survival) and inactivation cross-section for reproductive death (σ[R]) began to increase when LET exceeded 100 keV/μm. The exclusion of non-hit fraction in the calculation of surviving fraction partially prevented the fall of RBE[R] when LET exceeded 200 keV/μm. On the other hand, the mean number of lethal damage per unit dose (NLD/Gy) showed the same LET-dependent pattern as RBE[R]. These suggest that the increase in non-hit fraction and σ[R] with an increasing LET is caused by enhanced clustering of ionization and DNA damage

Development and external validation of a clinical prognostic score for death in visceral leishmaniasis patients in a high HIV co-infection burden area in Ethiopia.

Directory of Open Access Journals (Sweden)

Charles Abongomera

Full Text Available In Ethiopia, case fatality rates among subgroups of visceral leishmaniasis (VL patients are high. A clinical prognostic score for death in VL patients could contribute to optimal management and reduction of these case fatality rates. We aimed to identify predictors of death from VL, and to develop and externally validate a clinical prognostic score for death in VL patients, in a high HIV co-infection burden area in Ethiopia.We conducted a retrospective cohort study in north west Ethiopia. Predictors with an adjusted likelihood ratio ≥1.5 or ≤0.67 were retained to calculate the predictor score. The derivation cohort consisted of 1686 VL patients treated at an upgraded health center and the external validation cohort consisted of 404 VL patients treated in hospital. There were 99 deaths in the derivation cohort and 53 deaths in the external validation cohort. The predictors of death were: age >40 years (score +1; HIV seropositive (score +1; HIV seronegative (score -1; hemoglobin ≤6.5 g/dl (score +1; bleeding (score +1; jaundice (score +1; edema (score +1; ascites (score +2 and tuberculosis (score +1. The total predictor score per patient ranged from -1 to +5. A score of -1, indicated a low risk of death (1.0%, a score of 0 an intermediate risk of death (3.8% and a score of +1 to +5, a high risk of death (10.4-85.7%. The area under the receiver operating characteristic curve was 0.83 (95% confidence interval: 0.79-0.87 in derivation, and 0.78 (95% confidence interval: 0.72-0.83 in external validation.The overall performance of the score was good. The score can enable the early detection of VL cases at high risk of death, which can inform operational, clinical management guidelines, and VL program management. Implementation of focused strategies could contribute to optimal management and reduction of the case fatality rates.

Sudden unexpected death in epilepsy is a major cause of premature death in people with epilepsy. We aimed to assess whether structural changes potentially attributable to sudden death pathogenesis were present on magnetic resonance imaging in people who subsequently died of sudden unexpected death in epilepsy. In a retrospective, voxel-based analysis of T1 volume scans, we compared grey matter volumes in 12 cases of sudden unexpected death in epilepsy (two definite, 10 probable; eight males), acquired 2 years [median, interquartile range (IQR) 2.8] before death [median (IQR) age at scanning 33.5 (22) years], with 34 people at high risk [age 30.5 (12); 19 males], 19 at low risk [age 30 (7.5); 12 males] of sudden death, and 15 healthy controls [age 37 (16); seven males]. At-risk subjects were defined based on risk factors of sudden unexpected death in epilepsy identified in a recent combined risk factor analysis. We identified increased grey matter volume in the right anterior hippocampus/amygdala and parahippocampus in sudden death cases and people at high risk, when compared to those at low risk and controls. Compared to controls, posterior thalamic grey matter volume, an area mediating oxygen regulation, was reduced in cases of sudden unexpected death in epilepsy and subjects at high risk. The extent of reduction correlated with disease duration in all subjects with epilepsy. Increased amygdalo-hippocampal grey matter volume with right-sided changes is consistent with histo-pathological findings reported in sudden infant death syndrome. We speculate that the right-sided predominance reflects asymmetric central influences on autonomic outflow, contributing to cardiac arrhythmia. Pulvinar damage may impair hypoxia regulation. The imaging findings in sudden unexpected death in epilepsy and people at high risk may be useful as a biomarker for risk-stratification in future studies. The Author (2015).

Sudden Cardiac Death (SCD) is responsible for at least 180,000 deaths a year and incurs an average cost of $286 billion annually in the United States alone. Herein, we present a novel discrete event simulation model of SCD, which quantifies the chains of events associated with the formation, growth, and rupture of atheroma plaques, and the subsequent formation of clots, thrombosis and on-set of arrhythmias within a population. The predictions generated by the model are in good agreement both with results obtained from pathological examinations on the frequencies of three major types of atheroma, and with epidemiological data on the prevalence and risk of SCD. These model predictions allow for identification of interventions and importantly for the optimal time of intervention leading to high potential impact on SCD risk reduction (up to 8-fold reduction in the number of SCDs in the population) as well as the increase in life expectancy.

The purpose of this research was to compare the causes of death in 5 villages situated in Simav Plain, Turkey, during 2005-2010 where different arsenic levels were detected in drinking water supplies. Since groundwater in Simav Plain had arsenic concentrations that ranged between 7.1 and 833.9 ppb, a two-phase research was formulated. In the first phase, public health surveys were conducted with 1,003 villagers to determine the distribution of diseases. In the second phase, verbal autopsy surveys and official death records were used to investigate the causes of death. In total, 402 death cases were found in the study area where cardiovascular system diseases (44%) and cancers (15.2%) were major causes. Cancers of lung (44.3%), prostate (9.8%), colon (9.8%), and stomach (8.2%) were comparably higher in villages with high arsenic levels in drinking water supplies. Furthermore, the majority of cases of liver, bladder, and stomach cancers were observed in villages with high arsenic levels.

Utilizing a particular case study of a woman attempting to come to terms with her death, this article explores the difficult metaphors of death present within the Christian tradition. Tracing a Christian understanding of death back to the work of Augustine, the case study is utilized to highlight the difficulties presented by past and present theology embracing ideas of punishment within death. Following the trajectory of the case study, alternative understandings of death present in recent Christian theology and within Native American spirituality are presented in an attempt to find room for a fuller meaning of death post-reconciliation, but premortem.

Risk, control and self-identity

AIM - This article explores how young Danish drunk (and drug) drivers relate to the risk of driving under the influence (DUI). DESIGN - The study is based on qualitative interviews with 25 convicted drunk drivers who in 2010 participated in mandatory alcohol and traffic safety courses. The analysis...... follows Stephen Lyng’s concept of “edgework”, focusing on volitional risk taking and its effect on the acting individual’s self-identity. RESULTS - Drawing on the interviewees’ accounts of being arrested for drunk driving, the analysis discusses three different categories of young drunk drivers. Those...... in the first category view a DUI arrest as a loss of control and a reminder of the risk of DUI. Those in the second present DUI as a reaction to what they perceive as untenable social demands. Those in the third see loss of control - such as causing a traffic accident - as the ultimate way of claiming control...

Few previous studies of metabolic aberrations and prostate cancer risk have taken into account the fact that men with metabolic aberrations have an increased risk of death from causes other than prostate cancer. The aim of this study was to calculate, in a real-life scenario, the risk of prostate cancer diagnosis, prostate cancer death, and death from other causes. In the Metabolic Syndrome and Cancer Project, prospective data on body mass index, blood pressure, glucose, cholesterol, and triglycerides were collected from 285,040 men. Risks of prostate cancer diagnosis, prostate cancer death, and death from other causes were calculated by use of competing risk analysis for men with normal (bottom 84%) and high (top 16%) levels of each factor, and a composite score. During a mean follow-up period of 12 years, 5,893 men were diagnosed with prostate cancer, 1,013 died of prostate cancer, and 26,328 died of other causes. After 1996, when prostate-specific antigen testing was introduced, men up to age 80 years with normal metabolic levels had 13% risk of prostate cancer, 2% risk of prostate cancer death, and 30% risk of death from other causes, whereas men with metabolic aberrations had corresponding risks of 11%, 2%, and 44%. In contrast to recent studies using conventional survival analysis, in a real-world scenario taking risk of competing events into account, men with metabolic aberrations had lower risk of prostate cancer diagnosis, similar risk of prostate cancer death, and substantially higher risk of death from other causes compared with men who had normal metabolic levels.

Background In 2000, the overall rate of injury deaths in children aged 0–14 was 28.7 per 100000 in Estonia, which is more than 5 times higher than the corresponding rate in neighbouring Finland. This paper describes childhood injury mortality in Estonia by cause and age groups, and validates registration of these deaths in the Statistical Office of Estonia against the autopsy data. Methods The data on causes of all child deaths in Estonia in 2001–2005 were abstracted from the autopsy protocols at the Estonian Bureau of Forensic Medicine. Average annual mortality rates per 100,000 were calculated. Coverage (proportion of the reported injury deaths from the total number of injury deaths) and accuracy (proportion of correctly classified injury deaths) of the registration of causes of death in Statistical Office of Estonia were assessed by comparing the Statistical Office of Estonia data with the data from Estonian Bureau of Forensic Medicine. Results Average annual mortality from external causes in 0–14 years-old children in Estonia was 19.1 per 100,000. Asphyxia and transport accidents were the major killers followed by poisoning and suicides. Relative contribution of these causes varied greatly between age groups. Intent of death was unknown for more than 10% of injury deaths. Coverage and accuracy of registration of injury deaths by Statistical Office of Estonia were 91.5% and 95.3%, respectively. Conclusion Childhood mortality from injuries in Estonia is among the highest in the EU. The number of injury deaths in Statistical Office of Estonia is slightly underestimated mostly due to misclassification for deaths from diseases. Accuracy of the Statistical Office of Estonia data was high with some underestimation of intentional deaths. Moreover, high proportion of death with unknown intent suggests underestimation of intentional deaths. Reduction of injury deaths should be given a high priority in Estonia.

Divertor ‘death-ray’ explained: An artifact of a Langmuir probe operating at negative bias in a high-recycling divertor

International Nuclear Information System (INIS)

Brunner, D.; Umansky, M.V.; LaBombard, B.; Rognlien, T.D.

2013-01-01

The divertor ‘death-ray’, enhanced plasma pressure near the outer strike-point relative to ‘upstream’ values, was thought to correspond to axisymmetric increased divertor heat flux. Recent measurements on Alcator C-Mod show that the ‘death-ray’ is localized to biased Langmuir probes. Heat fluxes deduced from plasma-sheath theory and surface thermocouples agree in sheath-limited and moderate-recycling regimes. They diverge in high-recycling and detached regimes; surface thermocouples measure reduced heat flux while a ‘death-ray’ appears on Langmuir probes. The ‘death-ray’ is caused by the probe’s negative bias affecting the local flux tube. With the bias, electron heat flux to the probe surface is reduced. Thus, the local electron temperature is raised, enhancing neutral ionization and increasing the ion flux to the probe. The plasma fluid code UEDGE is used to simulate and reproduce many of the features of this integrated biased probe/divertor system

Actual innocence: is death different?

Science.gov (United States)

Acker, James R

2009-01-01

Supreme Court jurisprudence relies heavily on the premise that "death is different" from other criminal sanctions, and that capital cases entail commensurately demanding standards of reliability. Although invoked most frequently with respect to sentencing, both precedent and logic suggest that heightened reliability applies as well to guilt determination in capital trials. Nevertheless, recurrent and highly visible wrongful convictions in capital cases have affected public opinion, contributed to a precipitous decline in new death sentences, and led to calls for reforms designed to guard against the risk of executing innocent persons. This article examines the implications of the "death is different" doctrine for the problem of wrongful convictions in both capital and non-capital cases. It argues that innovations designed to enhance reliability in the special context of death-penalty prosecutions are important in their own right, but relevant new safeguards also should extend to criminal cases generally, where innocent people are similarly at risk and wrongful convictions are far more prevalent.

Full Text Available When the tide of unemployment hit the USA and Europe, in Japan the opposite phenomenon occurs. In 2002, in Japan deaths were recorded because of excessive works. In this country, the phenomenon of death because of excessive works is called Karoshi. Karoshi is common in Japan.  It becomes deadly syndrome as a consequence of long hours works. The debate about deaths from excessive work already sticking out in Japan since the 70s. The first official case of Karoshi was reported in 1969 when a 29-year-old male worker died because of stroke. It is estimated over ten thousand workers died each year due to death by brain and stroke caused by an overload work. Karoshi often happen to male workers dominantly. The main cause of karoshi is stress due to high pressure in the work environment, and work habits of exceeding a  standard of normal working time (8 hours. In addition, their extra time to work is imbalance with and the salary they earn. In its development, the phenomenon of karoshi contributes to the term salaryman and workaholic.

Quality insights of university teachers on dying, death, and death education.

Science.gov (United States)

Mak, Mui-Hing June

One of the main responsibilities of teachers is to help individual students cope with life difficulties such as grief following a death. However, very little research explores teachers' views on death, dying, and how they handle grief and loss in schools. This study aims to explore university teachers' knowledge and attitudes on dying, death, and death education. Fifteen university teachers were recruited using a qualitative method. This study reveals that most teachers' views on death and related issues are largely affected by their death experiences, religious beliefs, professional background, and the mass media. Although they have a general negative response toward death and dying, some teachers begin to affirm their meanings of life and death. Most teachers agree that they do not feel adequate about managing and teaching on life and death issues, so they strongly support including death education in the formal programs in Hong Kong.

%) did not. For surviving patients the instantaneous risk of death at any one time (the cause-specific death rate expressed as deaths per 100 cases per month), showed a sharp peak for MH deaths between 9 and 12 months post ILT in contradistinction to OC death where the peak was between 3 and 6 months post ILT. These findings may imply a role for late radiation reaction in the treatment-related risk factors identified as increasing the relative risk of MH death and possible mechanisms are discussed. The results have implications for treatment regimes that use a dose of 2000 cGy at 1 cm in a single fraction technique, that have a high frequency of previous laser treatment, that use multiple, repeated ILT treatments in the same location and that use ILT concurrently with EB

Pedestrian deaths in children--potential for prevention.

2015-01-01

The National Paediatric Mortality Database was reviewed for the six year period 1st January 2006 to 31st December 2011 and all pedestrian deaths extracted, after review of available data the deaths were categorized as either traffic or non-traffic related. There were 45 child pedestrian fatalities in the period examined. Traffic related deaths accounted for 26 (58%) vs. 19 (42%) non-traffic related. Analysis of the deaths showed there was a male preponderance 28 (62%), weekend trend 22 (49%) with an evening 16 (35%) and summer peak 20 (44%). The highest proportion of deaths occurred in the 1-4 year age group 24 (53%), with 13 (28%) due to low speed vehicle rollovers, mainly occurring in residential driveways 8 (61%). Child pedestrian fatalities are highly preventable through the modification of risk factors including behavioural, social and environmental. Preventative action needs to be addressed, particularly in relation to non-traffic related deaths i.e, low speed vehicle rollovers.

The definition of sudden death due to arrhythmia relies on the time interval between onset of symptoms and death. However, not all sudden deaths are due to arrhythmia. In patients with an implantable cardioverter defibrillator (ICD), postmortem device interrogation may help better distinguish the mode of death compared to a time-based definition alone. This study aims to assess the proportion of "sudden" cardiac deaths in patients with an ICD that have confirmed arrhythmia. We conducted a literature search for studies using postmortem ICD interrogation and a time-based classification of the mode of death. A modified QUADAS-2 checklist was used to assess risk of bias in individual studies. Outcome data were pooled where sufficient data were available. Our search identified 22 studies undertaken between 1982 and 2015 with 23,600 participants. The pooled results (excluding studies with high risk of bias) suggest that ventricular arrhythmias are present at the time of death in 76% of "sudden" deaths (95% confidence interval [CI] 67-85; range 42-88). Postmortem ICD interrogation identifies 24% of "sudden" deaths to be nonarrhythmic. Postmortem device interrogation should be considered in all cases of unexplained sudden cardiac death. © 2018 Wiley Periodicals, Inc.

Exploring children's understanding of death: through drawings and the Death Concept Questionnaire.

To investigate whether children's understanding of the concept of death varies as a function of death experience and age, 52 children aged 7, 9, and 11 years (26 had a personal death experience), drew a picture reflecting the meaning of the word death and completed the Death Concept Questionnaire for examination of Human and Animal Death. The results showed that the 2 methodological tools used offered complementary information and that children's understanding of death is related both to age and past experience. Children with death experience seem to have a more realistic understanding of death than their inexperienced age-mates. As regards to the effect of age, our findings support the assumption that the different components of death develop through different processes.

The circumstances surrounding the deaths of 75 asthmatic patients who had been prescribed a domiciliary nebuliser driven by an air compressor pump for administration of high dose beta sympathomimetic drugs were investigated as part of the New Zealand national asthma mortality study. Death was judged unavoidable in 19 patients who seemed to have precipitous attacks despite apparently good long term management. Delays in seeking medical help because of overreliance on beta agonist delivered by nebuliser were evident in 12 cases and possible in a further 11, but these represented only 8% of the 271 verified deaths from asthma in New Zealanders aged under 70 during the period. Evidence for direct toxicity of high dose beta agonist was not found. Nevertheless, the absence of serum potassium and theophylline concentrations and of electrocardiographic monitoring in the period immediately preceding death precluded firm conclusions whether arrhythmias might have occurred due to these factors rather than to hypoxia alone. In most patients prescribed domiciliary nebulisers death was associated with deficiencies in long term and short term care similar to those seen in patients without nebulisers. Discretion in prescribing home nebulisers, greater use of other appropriate drugs, including adequate corticosteroids, and careful supervision and instruction of patients taking beta agonist by nebuliser should help to reduce the mortality from asthma.

Objective: To further analyze non-cancer mortality rates and relevant influencing factors among the residents in high background radiation area(HBRA) and its control area (CA). Methods: The data for the period 1987-1995 were obtained from a fixed cohort by prospective survey. The mortality investigation on the spot consisted of two steps, i.e. the follow-up of the cohort members and the ascertainment of causes of death. On the basis of the hamlet-specific average of annual external dose, the cohort members were classified into four groups for internal comparison: high, medial and low dose groups in HBRA and control group in CA. Relative risk (RR), excess relative risk(ERR/Sv) and its 95% confidence interval (CI) were estimated using AMFIT program in Epicure. Results: During the period 1987-1995, the noncancer mortality in HBRA increased by 9% compared with that in the control group, and the relative risk of noncancer diseases was 1.09 (P=0.01), indicating a statistically significant excess mortality in the HBRA. The significantly increased noncancer death was caused by diseases of digestive system, with a RR of 1.46(P=0.006); the relative risk of chronic liver diseases including cirrhosis was 1.98(P=0.004). The significantly decreased noncancer death rates were observed for the infectious and parasitic diseases, the RR being 0.81(P=0.04); for pulmonary tuberculosis, RR 0.58(P<0.001). The homogeneity tests of risks across the four dose-groups revealed that the RRs for diseases of digestive system and for liver cirrhosis were significantly different, P values being 0.01 and 0.04, respectively. The ERR(95% CI)/Sv for diseases of digestive system and liver cirrhosis were 2.18(0.22, 7.64) and 10.94(1.34, NA), respectively. Conclusion: The death rates from diseases of digestive system, especially chronic liver diseases and cirrhosis were statistically significantly higher, and that from pulmonary tuberculosis was significantly lower in the HBRA than those in the control

To study long-term mortality and causes of death in a cohort of drug users in relation to main type of drug use and HIV-status. A total of 1640 hospitalized drug users in Stockholm was followed up from 1985 to the end of 2007. The mortality was compared with the general Swedish population and hazard ratios (HR) for the main risk indicators were calculated. The causes of death were studied, using information from death certificates. 630 persons died during the observation period. The Standard Mortality Ratio (SMR) was 16.1 (males 13.8, females 18.5). The crude mortality rate was 2.0 % (males 2.2% and females 1.5%). The mortality rate was higher in heroin users than among amphetamine users, HR 1.96, controlled for age and other risk factors. The mortality rate among individuals infected with the human immunodeficiency virus (HIV) was high (4.9 %), HR 2.64, compared with HIV-negative individuals. Most of the deaths were from other causes than acquired immune deficiency syndrome. One-third of deaths (227) were caused by heroin intoxication. The number of deaths from HIV-related causes decreased after 1996, when highly active anti-retroviral therapy was introduced. In all, there were 92 HIV-related deaths. Deaths from natural causes increased during the observation period. The SMR was highest for cardiovascular and gastrointestinal diseases. The results indicate a correlation between amphetamine use and death from cerebral haemorrhage. A high proportion of natural deaths were alcohol-related. The death rate among illicit drug users was persistently high. Alcohol consumption was a contributing factor to premature death. © 2014 the Nordic Societies of Public Health.

The present study aimed to examine the level of death anxiety, the sex-related differences among a middle-aged Kuwaiti personnel sample, and to explore the replicability of the Arabic Scale of Death Anxiety (ASDA) factors. A sample of 236 volunteer Kuwaiti personnel took part in the study. The mean ages of men and women were 41.5 (SD = 7.5) and 40.9 (SD = 7.1), respectively. The alpha reliability of the ASDA was found to be high (.93). Women had a significantly higher mean total score on the ASDA as well as on 17 out of its 20 items. Middle-aged personnel had a significantly lower mean ASDA total score than younger college students (M age = 22). The factor analysis of the ASDA items yielded three factors: fear of dead people and tombs; fear of postmortem events; and fear of lethal disease. These factors were highly replicable with previous factors extracted from a Kuwaiti college student sample. On the basis of the present findings, there are three general conclusions as follows: death anxiety is negatively associated with age; the sex-related differences on death anxiety are salient in the Arab samples; and the ASDA has a highly replicable factor structure.

Death in children with epilepsy is profoundly disturbing, with lasting effects on the family, community, and health care providers. The overall risk of death for children with epilepsy is about ten times that of the general population. However, the risk of premature death for children without associated neurological comorbidities is similar to that of the general population, and most deaths are related to the cause of the epilepsy or associated neurological disability, not seizures. The most common cause of seizure-related death in children with epilepsy is sudden unexpected death in epilepsy (SUDEP). SUDEP is relatively uncommon in childhood, but the risk increases if epilepsy persists into adulthood. Although the direct cause of SUDEP remains unknown, most often death follows a generalized convulsive seizure and the risk of SUDEP is strongly related to drug-resistant epilepsy and frequent generalized tonic-clonic seizures. The most effective SUDEP prevention strategy is to reduce the frequency of seizures, although a number of seizure detection devices are under development and in the future may prove to be useful for seizure detection for those at particularly high risk. There are distinct benefits for health care professionals to discuss mortality with the family soon after the diagnosis of epilepsy. An individual approach is appropriate. When a child with epilepsy dies, particularly if the death was unexpected, family grief may be profound. Physicians and other health care professionals have a critical role in supporting families that lose a child to epilepsy. This review will provide health care providers with information needed to discuss the risk of death in children with epilepsy and support families following a loss. Copyright © 2017 Elsevier Inc.

Countries that conduct systematic child death reviews report a high proportion of modifiable characteristics among deaths from external causes, and this study examined the trends in Sweden. We analysed individual-level data on external, ill-defined and unknown causes from the Swedish cause of death register from 2000 to 2014, and mortality rates were estimated for children under the age of one and for those aged 1-14 and 15-17 years. Child deaths from all causes were 7914, and 2006 (25%) were from external, ill-defined and unknown causes: 610 (30%) were infants, 692 (34%) were 1-14 and 704 (35%) were 15-17. The annual average was 134 cases (range 99-156) during the study period. Mortality rates from external, ill-defined and unknown causes in children under 18 fell 19%, from 7.4 to 6.0 per 100 000 population. A sizeable number of infant deaths (8.0%) were registered without a death certificate during the study period, but these counts were lower in children aged 1-14 (1.3%) and 15-17 (0.9%). Childhood deaths showed a sustained decline from 2000 to 2014 in Sweden and a quarter were from external, ill-defined or unknown causes. Systematic, interagency death reviews could yield information that could prevent future deaths. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

We studied the distribution of deaths from ill-defined causes that occurred in Brazil during 2003, from which was identified the proportion of unattended deaths. Data were obtained from the Mortality Information System, coordinated by the Ministry of Health. Causes of death included in "Chapter XVIII - Symptoms, signs and abnormal clinical and laboratory findings, not classified elsewhere" of the International Statistical Classification of Diseases and Related Health Problems, tenth revision, were considered ill-defined, among which the category R98 identified "unattended deaths". In Brazil during 2003 the underlying causes of 13.3% of deaths were included in the Chapter of ill-defined causes, and the highest proportions of these deaths occurred in the Northeast and North Regions. Considering the total deaths from ill-defined causes, 53 % correspond to unattended deaths. This proportion increased to over 70% in the states of Maranhão, Piauí, Rio Grande do Norte, Pernambuco, Bahia, Paraíba and Alagoas. Due to the decentralized structure of data collection in the country, we believe that the municipalities bear the major responsibility, followed by the states, for upgrading the quality of mortality statistics.

To explore potential relationships between HIV and highly active anti-retroviral therapy (HAART), and hypertensive disorders of pregnancy (HDP). A retrospective secondary analysis of maternal-deaths data from the 2011-2013 Saving Mothers Report from South Africa. The incidence of HIV infection amongst individuals who died owing to HDP was determined and comparisons were made based on HIV status and the use of HAART. Among 4452 maternal deaths recorded in the Saving Mothers report, a lower risk of a maternal deaths being due to HDP was observed among women who had HIV infections compared with women who did not have HIV (relative risk [RR] 0.57, 95% confidence interval [CI] 0.51-0.64). Further, reduced odds of death being due to HDP were recorded among women with AIDS not undergoing HAART compared with women with HIV who did not require treatment (RR 0.42, 95% CI 0.3-0.58). Notably, among all women with AIDS, a greater risk of death due to HDP was demonstrated among those who received HAART compared with those who did not (RR 1.15, 95% CI 1.02-1.29). HIV and AIDS were associated with a decreased risk of HDP being the primary cause of death; the use of HAART increased this risk. © 2016 International Federation of Gynecology and Obstetrics.

To follow up populations exposed to several radiation accidents in the Southern Urals, a cause-of-death registry was established at the Urals Center capturing deaths in the Chelyabinsk, Kurgan and Sverdlovsk region since 1950. When registering deaths over such a long time period, quality measures need to be in place to maintain quality and reduce the impact of individual coders as well as quality changes in death certificates. To ensure the uniformity of coding, a method for semi-automatic coding was developed, which is described here. Briefly, the method is based on a dynamic thesaurus, database-supported coding and parallel coding by two different individuals. A comparison of the proposed method for organizing the coding process with the common procedure of coding showed good agreement, with, at the end of the coding process, 70  - 90% agreement for the three-digit ICD -9 rubrics. The semi-automatic method ensures a sufficiently high quality of coding by at the same time providing an opportunity to reduce the labor intensity inherent in the creation of large-volume cause-of-death registries.

On social death: ostracism and the accessibility of death thoughts.

Steele, Caroline; Kidd, David C; Castano, Emanuele

2015-01-01

Being rejected, excluded, or simply ignored is a painful experience. Ostracism researchers have shown its powerful negative consequences (Williams, 2007), and sociologists have referred to such experiences as social death (Bauman, 1992). Is this is just a metaphor or does being ostracized make death more salient in people's minds? An experiment was conducted in which participants experienced ostracism or inclusion using the Cyberball manipulation, and the accessibility of death-related thoughts was measured via a word-stem completion puzzle. Results showed enhanced death-thought accessibility in the ostracism condition, as well as a negative effect of dispositional self-esteem on the accessibility of death-related thoughts.

We examined the socio-demographic distribution of gun deaths across 3143 counties in 50 United States' states to understand the spatial patterns and correlates of high and low gun deaths. We used aggregate counts of gun deaths and population in all counties from 1999 to 2013 from the Centers for Disease Control and Prevention's Wide-ranging Online Data for Epidemiologic Research (WONDER). We characterized four levels of gun violence, as distinct levels of gun death rates of relatively safe, unsafe, violent, and extremely violent counties, based on quartiles of 15-year county-specific gun death rates per 100,000 and used negative binomial regression models allowing clustering by state to calculate incidence rate ratios and 95% confidence intervals (95% CIs). Most states had at least one violent or extremely violent county. Extremely violent gun counties were mostly rural, poor, predominantly minority, had high unemployment rate and homicide rate. Overall, homicide rate was significantly associated with gun deaths (incidence rate ratios = 1.08, 95% CI = 1.06-1.09). In relatively safe counties, this risk was 1.09 (95% CI = 1.05-1.13) and in extremely violent gun counties was 1.03 (95% CI = 1.03-1.04). There are broad differences in gun death rates across the United States representing different levels of gun death rates in each state with distinct socio-demographic profiles.

Overfeeding amino acids (AAs) increases cellular exposure to advanced glycation end-products (AGEs), a mechanism for protein intake to worsen diabetic kidney disease (DKD). This study assessed receptor for AGE (RAGE)-mediated apoptosis and inflammation in glomerular cells exposed to metabolic stressors characteristic of high-protein diets and/or diabetes in vitro with proof-of-concept appraisal in vivo. Mouse podocytes and mesangial cells were cultured under control and metabolic stressor conditions: (i) no addition; (ii) increased AAs (4-6-fold>control); (iii) high glucose (HG, 30.5 mM); (iv) AA/HG combination; (v) AGE-bovine serum albumin (AGE-BSA, 300 µg/mL); (vi) BSA (300 µg/mL). RAGE was inhibited by blocking antibody. Diabetic (streptozotocin) and nondiabetic mice (C57BL/6J) consumed diets with protein calories of 20 or 40% (high) for 20 weeks. People with DKD and controls provided 24-h urine samples. In podocytes and mesangial cells, apoptosis (caspase 3/7 activity and TUNEL) increased in all metabolic stressor conditions. Both inflammatory mediator expression (real-time reverse transcriptase-polymerase chain reaction: serum amyloid A, caspase-4, inducible nitric oxide synthase, and monocyte chemotactic protein-1) and RAGE (immunostaining) also increased. RAGE inhibition prevented apoptosis and inflammation in podocytes. Among mice fed high protein, podocyte number (WT-1 immunostaining) decreased in the diabetic group, and only these diabetic mice developed albuminuria. Protein intake (urea nitrogen) correlated with AGE excretion (carboxymethyllysine) in people with DKD and controls. High-protein diet and/or diabetes-like conditions increased glomerular cell death and inflammation, responses mediated by RAGEs in podocytes. The concept that high-protein diets exacerbate early indicators of DKD is supported by data from mice and people.

Vaginal delivery is recommended after intrauterine fetal death. However, little is known about the risk of shoulder dystocia in these deliveries. We studied whether intrauterine fetal death increases the risk of shoulder dystocia at delivery. In this population-based register study using the Medical Birth Registry of Norway, we included all singleton pregnancies with vaginal delivery of offspring in cephalic presentation in Norway during the period 1967-2012 (n = 2 266 118). Risk of shoulder dystocia was estimated as absolute risk (%) and odds ratio with 95% confidence interval. Adjustment was made for offspring birthweight (in grams). We performed sub-analyses within categories of birthweight (dystocia occurred in 1.1% of pregnancies with intrauterine fetal death and in 0.8% of pregnancies without intrauterine fetal death (p dystocia occurred in 14.6% of pregnancies with intrauterine fetal death and in 2.8% of pregnancies without intrauterine fetal death (p dystocia occurred in 57.1% of pregnancies with intrauterine fetal death and 9.6% of pregnancies without intrauterine fetal death (p dystocia at delivery, and the absolute risk of shoulder dystocia was particularly high if offspring birthweight was high and the mother had diabetes. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

Transient regulation of Plasmodium numbers below the density that induces fever has been observed in chronic malaria infections in humans. This species transcending control cannot be explained by immunity alone. Using an in vitro system we have observed density dependent regulation of malaria population size as a mechanism to possibly explain these in vivo observations. Specifically, Plasmodium falciparum blood stages from a high but not low-density environment exhibited unique phenotypic changes during the late trophozoite (LT) and schizont stages of the intraerythrocytic cycle. These included in order of appearance: failure of schizonts to mature and merozoites to replicate, apoptotic-like morphological changes including shrinking, loss of mitochondrial membrane potential, and blebbing with eventual release of aberrant parasites from infected erythrocytes. This unique death phenotype was triggered in a stage-specific manner by sensing of a high-density culture environment. Conditions of glucose starvation, nutrient depletion, and high lactate could not induce the phenotype. A high-density culture environment induced rapid global changes in the parasite transcriptome including differential expression of genes involved in cell remodeling, clonal antigenic variation, metabolism, and cell death pathways including an apoptosis-associated metacaspase gene. This transcriptional profile was also characterized by concomitant expression of asexual and sexual stage-specific genes. The data show strong evidence to support our hypothesis that density sensing exists in P. falciparum. They indicate that an apoptotic-like mechanism may play a role in P. falciparum density regulation, which, as in yeast, has features quite distinguishable from mammalian apoptosis.

Comparison of death certificate and autopsy diagnoses - Hiroshima. [Cause of death

Energy Technology Data Exchange (ETDEWEB)

Stone, R S; Anderson, Jr, P S

1960-09-14

In this report evaluation of the death certificates has been on the basis of comparison with recorded autopsy diagnoses without review of the latter. An attempt has been made to evaluate limitations inherent in this method. The cases analyzed here represent the ABCC Hiroshima autopsy series from 1949 through 1959. Post mortem examinations on stillbirths and neonatal deaths that were collected during the years 1948 through 1953 were excluded from consideration because such cases are not pertinent to the general problems under study. With this limitation 1304 cases were available for matching. In 139 of these cases the death certificates were not available through the mechanisms of the overall study, so 1165 cases remained. Before comparisons are made the most important questions that must be answered about the materials and methods of the present investigation are: (1) is the autopsy-death certificate series a representative sample of all deaths in the population; (2) are the autopsy diagnoses correct; (3) are the death certificates properly understood and coded; and (4) are biologically meaningful groupings chosen for comparison between autopsy cause of death and death certificate cause of death. Because it is not possible to provide exact answers to all of these questions the doubt that they raise must be admitted but evaluated in the perspective of that part of the answer which is known.

Several studies have reported increased mortality during holidays. Using a cultural epidemiological, sequential mixed-methods approach, this study explored holiday-related trends using mortality data from Yautepec (Morelos, Mexico) collected between 1986 and 2008 (N=5027 deaths). This analysis found that mortality increased on Christmas Day and All Saints' Day. Mortality increased on Candlemas Day among women, and increased on New Year's Day among men. More deaths caused by cardiovascular disease among women and traumatic injuries among men occurred during holidays than in non-holiday periods. To ascertain the elements comprising the health/illness/death process in the context of a holiday in this municipality, we conducted semi-structured interviews in March and April 2009 with relatives of seven individuals who had died during holidays in the previous 4 years (N=11); data from these interviews were analyzed from a grounded theory perspective to ascertain common conceptual themes. The "beautiful death" emerged as the main concept in the interpretation of death; this concept was related to the expectation of a good death and the particularly special nature of death during a holiday because of the involvement of religious entities, such as God, the Virgin Mary, and/or a saint, at the moment of death. Quantitative and qualitative results provided information about the important effects of holidays, culture, and religious belief on mortality patterns within a Mexican context, and contributed to a better understanding of the relationships among mortality, the nature of death, and holidays. Our results suggest that, in the studied region, death can be interpreted as a "beautiful process". More research is needed to explore this process in other similar contexts and to address topics related to the care and attention given the dying person and the expectation of a good death.

BRAIN DEATH DIAGNOSIS

Directory of Open Access Journals (Sweden)

Calixto Machado

2009-10-01

Full Text Available Brain death (BD diagnosis should be established based on the following set of principles, i.e. excluding major confusing factors, identifying the cause of coma, determining irreversibility, and precisely testing brainstem reflexes at all levels of the brainstem. Nonetheless, most criteria for BD diagnosis do not mention that this is not the only way of diagnosing death. The Cuban Commission for the Determination of Death has emphasized the aforesaid three possible situations for diagnosing death: a outside intensive care environment (without life support physicians apply the cardio-circulatory and respiratory criteria; b in forensic medicine circumstances, physicians utilize cadaveric signs (they do not even need a stethoscope; c in the intensive care environment (with life support when cardiorespiratory arrest occurs physicians utilize the cardio-circulatory and respiratory criteria. This methodology of diagnosing death, based on finding any of the death signs, is not related to the concept that there are different types of death. The irreversible loss of cardio-circulatory and respiratory functions can only cause death when ischemia and anoxia are prolonged enough to produce an irreversible destruction of the brain. The sign of irreversible loss of brain functions, that is to say BD diagnosis, is fully reviewed.

Evaluating the extent of cell death in 3D high frequency ultrasound by registration with whole-mount tumor histopathology

Purpose: High frequency ultrasound imaging, 10-30 MHz, has the capability to assess tumor response to radiotherapy in mouse tumors as early as 24 h after treatment administration. The advantage of this technique is that the image contrast is generated by changes in the physical properties of dying cells. Therefore, a subject can be imaged before and multiple times during the treatment without the requirement of injecting specialized contrast agents. This study is motivated by a need to provide metrics of comparison between the volume and localization of cell death, assessed from histology, with the volume and localization of cell death surrogate, assessed as regions with increased echogeneity from ultrasound images. Methods: The mice were exposed to radiation doses of 2, 4, and 8 Gy. Ultrasound images were collected from each tumor before and 24 h after exposure to radiation using a broadband 25 MHz center frequency transducer. After radiotherapy, tumors exhibited hyperechoic regions in ultrasound images that corresponded to areas of cell death in histology. The ultrasound and histological images were rigidly registered. The tumors and regions of cell death were manually outlined on histological images. Similarly, the tumors and hyperechoic regions were outlined on the ultrasound images. Each set of contours was converted to a volumetric mesh in order to compare the volumes and the localization of cell death in histological and ultrasound images. Results: A shrinkage factor of 17±2% was calculated from the difference in the tumor volumes evaluated from histological and ultrasound images. This was used to correct the tumor and cell death volumes assessed from histology. After this correction, the average absolute difference between the volume of cell death assessed from ultrasound and histological images was 11±14% and the volume overlap was 70±12%. Conclusions: The method provided metrics of comparison between the volume of cell death assessed from histology and

miR-Let7A Controls the Cell Death and Tight Junction Density of Brain Endothelial Cells under High Glucose Condition.

Hyperglycemia-induced stress in the brain of patients with diabetes triggers the disruption of blood-brain barrier (BBB), leading to diverse neurological diseases including stroke and dementia. Recently, the role of microRNA becomes an interest in the research for deciphering the mechanism of brain endothelial cell damage under hyperglycemia. Therefore, we investigated whether mircoRNA Let7A (miR-Let7A) controls the damage of brain endothelial (bEnd.3) cells against high glucose condition. Cell viability, cell death marker expressions (p-53, Bax, and cleaved poly ADP-ribose polymerase), the loss of tight junction proteins (ZO-1 and claudin-5), proinflammatory response (interleukin-6, tumor necrosis factor- α ), inducible nitric oxide synthase, and nitrite production were confirmed using MTT, reverse transcription-PCR, quantitative-PCR, Western blotting, immunofluorescence, and Griess reagent assay. miR-Let7A overexpression significantly prevented cell death and loss of tight junction proteins and attenuated proinflammatory response and nitrite production in the bEnd.3 cells under high glucose condition. Taken together, we suggest that miR-Let7A may attenuate brain endothelial cell damage by controlling cell death signaling, loss of tight junction proteins, and proinflammatory response against high glucose stress. In the future, the manipulation of miR-Let7A may be a novel solution in controlling BBB disruption which leads to the central nervous system diseases.

Recent innovations in care have improved survival following injury. Coincidentally, the population of elderly injured patients with preexisting comorbidities has increased. We hypothesized that this increase in elderly injured patients may have combined with recent care innovations to alter the causes of death after trauma. We reviewed demographics, injury characteristics, and cause of death of in-hospital deaths of patients admitted to our Level I trauma service from 2000 through 2011. Cause of death was classified as acute hemorrhagic shock; severe traumatic brain injury or high spinal cord injury; complications of preexisting medical condition only (PM); survivable trauma combined with complications of preexisting medical condition (TCoM); multiple-organ failure, sepsis, or adult respiratory distress syndrome (MOF/S/ARDS), or trauma not otherwise categorized (e.g., asphyxiation). Major trauma care advances implemented on our service during the period were identified, and trends in the causes of death were analyzed. Of the 27,276 admissions, 819 (3%) eligible nonsurvivors were identified for the cause-of-death analyses. Causes of death were severe traumatic brain injury or high spinal cord injury at 44%, acute hemorrhagic shock at 28%, PM at 11%, TCoM at 10%, MOF/S/ARDS at 2%, and trauma not otherwise categorized at 5%. Mean age at death increased across the study interval (range, 47-57 years), while mean Injury Severity Score (ISS) decreased (range, 28-35). There was a significant increase in deaths because of TCoM (3.3-20.9%) and PM (6.7-16.4%), while deaths caused by MOF/S/ARDS decreased from 5% to 0% by 2007. Compared with year 2000, the annual adjusted mortality rate decreased consistently starting in 2009, after the 2002 to 2007 adoption of four major trauma practice guidelines. Mortality caused by preexisting medical conditions has increased, while markedly fewer deaths resulted from the complications of injury. Future improvements in outcomes will require

The control and execution of programmed cell death

Apoptosis or programmed cell death is a highly conserved genetically controlled response of metazoan cells to commit suicide. Non apoptotic programmed cell death seems to operate in single celled eukaryotes implying that evolution of PCD has preceded the evolution of multicellularity. PCD plays a crucial role in the regulation of cellular and tissue homeostasis and any aberrations in apoptosis leads to several diseases including cancer, neurodegenerative disorders and AIDS. The mechanisms by which apoptosis is controlled are varied. In some cells, members of bcl-2 family or p53 are crucial for regulating the apoptosis programme, whereas in other cells Fas ligand is more important. bcl-2 family members have a prime role in the regulation of cell death at all stages including development, whereas cell death during development is independent of p53. bcl-2 family members being localized on the outer mitochondrial membrane, control the mitochondrial homeostasis and cytochrome c redistribution and thereby regulate the cell death process. p53 promotes DNA damage mediated cell death after growth arrest and failed DNA repair. Caspases play a key role in the execution of cell death by mediating highly specific cleavages of crucial cellular proteins collectively manifesting the apoptotic phenotype. Protein inhibitors like crm A, p35 and IAPs could prevent/control apoptosis induced by a broad array of cell death stimuli by several mechanisms specially interfering in caspase activation or caspase activity. Among endonucleases, caspase activated DNase (CAD) plays a crucial role in DNA fragmentation, a biochemical hallmark of apoptosis. As regulation of cell death seems to be as complex as regulation of cell proliferation, multiple kinase mediated regulatory mechanisms might control the apoptotic process. Thus, in spite of intensive research over the past few years, the field of apoptosis still remains fertile to unravel among others, the molecular mechanisms of cytochrome c

Protein inhibitors like crm A, p35 and IAPs could prevent/control apoptosis induced by a broad array of cell death stimuli by several mechanisms specially interfering in caspase activation or caspase activity. Among endonucleases, caspase activated DNase (CAD) plays a crucial role in DNA fragmentation, a biochemical hallmark of apoptosis. As regulation of cell death seems to be as complex as regulation of cell proliferation, multiple kinase mediated regulatory mechanisms might control the apoptotic process. Thus, in spite of intensive research over the past few years, the field of apoptosis still remains fertile to unravel among others, the molecular mechanisms of cytochrome c

In a society characterized by the denial of old age and death, people are not satisfied with the mere promise of a hypothetical immortal life in the future. They value beauty, youth and high performance and consider aging an anomaly or random misfortune that can be avoided. To this end, people focus on making their bodies immortal here and now, and on living as if they were never going to die. The race for power and personal empowerment, compulsive consumption, and escape into the virtual world all go on as though death does not exist. Although this approach to living can sometimes give people a feeling of omnipotence, even immortality, we still cannot escape our mortality. The two extremes of existence--birth and death--are seen as medical problems that science and technology can solve.

Death certificates underestimate infections as proximal causes of death in the U.S.

Full Text Available Death certificates are a primary data source for assessing the population burden of diseases; however, there are concerns regarding their accuracy. Diagnosis-Related Group (DRG coding of a terminal hospitalization may provide an alternative view. We analyzed the rate and patterns of disagreement between death certificate data and hospital claims for patients who died during an inpatient hospitalization.We studied respondents from the Health and Retirement Study (a nationally representative sample of older Americans who had an inpatient death documented in the linked Medicare claims from 1993-2007. Causes of death abstracted from death certificates were aggregated to the standard National Center for Health Statistics List of 50 Rankable Causes of Death. Centers for Medicare and Medicaid Services (CMS-DRGs were manually aggregated into a parallel classification. We then compared the two systems via 2×2, focusing on concordance. Our primary analysis was agreement between the two data sources, assessed with percentages and Cohen's kappa statistic.2074 inpatient deaths were included in our analysis. 36.6% of death certificate cause-of-death codes agreed with the reason for the terminal hospitalization in the Medicare claims at the broad category level; when re-classifying DRGs without clear alignment as agreements, the concordance only increased to 61%. Overall Kappa was 0.21, or "fair." Death certificates in this cohort redemonstrated the conventional top 3 causes of death as diseases of the heart, malignancy, and cerebrovascular disease. However, hospitalization claims data showed infections, diseases of the heart, and cerebrovascular disease as the most common diagnoses for the same terminal hospitalizations.There are significant differences between Medicare claims and death certificate data in assigning cause of death for inpatients. The importance of infections as proximal causes of death is underestimated by current death certificate

Violent deaths are of considerable importance among young adults, since they account for half the deaths in this age group (average age 26.4 years). Suicide and accidents (both categories including drug overdoses) are the most frequent categories of deaths from non-natural causes, while in the USA deaths by homicide are also of considerable importance. Current repressive policies have not brought the problem of drug addiction under control. Each year deaths by overdose among drug abusers occur. Nevertheless, 40% of deaths among drug addicts are from other causes, principally accidents and suicides. In the near future, AIDS may well account for the majority of deaths among drug addicts, thus adding to the mortality from overdose, both accidental and suicidal. Has the time come to reconsider the problem of drug abuse and to find radical solutions which would previously have been unthinkable?

Settipane, G A

1989-01-01

We reviewed seven documented deaths to peanuts and two near deaths. We excluded hearsay undocumented deaths to peanuts. Peanut allergy is one of the most common food allergies and probably the most common cause of death by food anaphylaxis in the United States. About one-third of peanut-sensitive patients have severe reactions to peanuts. Asthmatics with peanut sensitivity appear more likely to develop fatal reactions probably because of the exquisite sensitivity that asthamatics have to chemical mediators of anaphylaxis. Severe reactions occur within a few minutes of ingestion and these patients must carry preloaded epinephrine syringes, antihistamines, and medic-alert bracelets. Treatment should include repeated doses of epinephrine, antihistamines and corticosteroids as well as availability of oxygen, mechanical methods to open airways, vasopressors, and intravenous fluids. Hidden sources of peanuts such as chili, egg rolls, cookies, candy, and pastry should be recognized and identified. Scratch/prick test to peanuts are highly diagnostic. Peanut is one of the most sensitive food allergens known requiring only a few milligrams to cause a reaction. In some individuals, even contact of peanut with unbroken skin can cause an immediate local reaction. Unfortunately, peanut reaction is not outgrown and remains a life-long threat.

Preventable trauma deaths: from panel review to population based-studies

Vesconi Sergio

2006-04-01

Full Text Available Abstract Preventable trauma deaths are defined as deaths which could be avoided if optimal care has been delivered. Studies on preventable trauma deaths have been accomplished initially with panel reviews of pre-hospital and hospital charts. However, several investigators questioned the reliability and validity of this method because of low reproducibility of implicit judgments when they are made by different experts. Nevertheless, number of studies were published all around the world and ultimately gained some credibility, particularly in regions where comparisons were made before and after trauma system implementation with a resultant fall in mortality. During the last decade of century the method of comparing observed survival with probability of survival calculated from large trauma registries has obtained popularity. Preventable trauma deaths were identified as deaths occurred notwithstanding a high calculated probability of survival. In recent years, preventable trauma deaths studies have been replaced by population-based studies, which use databases representative of overall population, therefore with high epidemiologic value. These databases contain readily available information which carry out the advantage of objectivity and large numbers. Nowadays, population-based researches provide the strongest evidence regarding the effectiveness of trauma systems and trauma centers on patient outcomes.

2016-02-01

Full Text Available Abstract Introduction: Death is defined as the permanent loss of all signs of life at any time after birth (Irrevocable disappearance of all vital signs after birth. Unnatural deaths seem to be either suspicious or  unexpected. Deaths that occur suddenly and their causes need to be investigated, are termed unnatural deaths. According to the death certificate contents of Ministry of Health and Forensics, if the cause of death is unnatural, the corpse will be submitted to the forensic medicine departments in 19 cases in order to determine the death cause and to issue the burial permit.   Material & Methods: In this descriptive study, the data were extracted from unnatural death cases in the province of Yazd during 2003 to 2013 recorded by Yazd Forensic Medicine. Results: During 2003 -2013, 5552 cases of unnatural deaths were recorded by the Forensic Medicine of Yazd, out of which 4373 cases of unnatural deaths were caused by road traffic accidents (outside and inside the city, 89 deaths from electrocution, 439 deaths from poisoning, 72 deaths from drowning, 129 deaths from asphyxia (by carbon monoxide, 56 deaths from work incidents, and 394 deaths from burns. The group of males aged 20-29 years allocated the highest number of unnatural deaths to themselves. Conclusion: Road traffic accidents are the second leading cause of unnatural deaths in Iran. The number of unnatural death incidents in men is more than women indicating that men are more exposed to risk factors than women, though regarding the deaths due to the burns, women are exposed to the high risk factors.

In this study we characterized the relationship between temperature and mortality in central Arizona desert cities that have an extremely hot climate. Relationships between daily maximum apparent temperature (ATmax) and mortality for eight condition-specific causes and all-cause deaths were modeled for all residents and separately for males and females ages heat. For this condition-specific cause of death, the heat thresholds in all gender and age groups (ATmax = 90-97 °F; 32.2-36.1 °C) were below local median seasonal temperatures in the study period (ATmax = 99.5 °F; 37.5 °C). Heat threshold was defined as ATmax at which the mortality ratio begins an exponential upward trend. Thresholds were identified in younger and older females for cardiac disease/stroke mortality (ATmax = 106 and 108 °F; 41.1 and 42.2 °C) with a one-day lag. Thresholds were also identified for mortality from respiratory diseases in older people (ATmax = 109 °F; 42.8 °C) and for all-cause mortality in females (ATmax = 107 °F; 41.7 °C) and males Heat-related mortality in a region that has already made some adaptations to predictable periods of extremely high temperatures suggests that more extensive and targeted heat-adaptation plans for climate change are needed in cities worldwide.

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

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.

We evaluated the association between meteorological conditions and sports deaths at elementary, junior high and senior high schools. Data were collected from attached documents such as accident reports and death certificate records in the National Agency for the Advancement of Sports and Health in Japan. Evaluation of seasonal variation showed a significant concentration of deaths from heat disorders and drowning in July and August. When heart disease was evaluated according to the sports situation, significant seasonal variation with a high number of deaths in September December was observed in sports events. Concerning circadian variation, deaths from heart disease showed a high peak at 10:00 11:00 a.m. in physical education classes and sports events, and at 2:00 5:00 p.m. in sports club activities. Analysis using a multiple logistic model showed a significantly lower odds ratio from heart disease and a significantly higher odds ratio from heat disorders at a wet bulb globe temperature of ≥21.0°C than at activities was significantly lower on days with rainfall than on days without rainfall. According to the school categories in heart diseases, the odds ratio in girls in elementary school was significantly higher than that in boys, but the odds ratio in girls in senior high school was significantly lower than that in boys.

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

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.

Freshwater mussel species with doubly uniparental inheritance (DUI) of mtDNA are unique because they are naturally heteroplasmic for two extremely divergent mtDNAs with ~50% amino acid differences for protein-coding genes. The paternally-transmitted mtDNA (or M mtDNA) clearly functions in sperm in these species, but it is still unknown whether it is transcribed when present in male or female soma. In the present study, we used PCR and RT-PCR to detect the presence and expression of the M mtDNA in male and female somatic and gonadal tissues of the freshwater mussel species Venustaconcha ellipsiformis and Utterbackia peninsularis (Unionidae). This is the first study demonstrating that the M mtDNA is transcribed not only in male gonads, but also in male and female soma in freshwater mussels with DUI. Because of the potentially deleterious nature of heteroplasmy, we suggest the existence of different mechanisms in DUI species to deal with this possibly harmful situation, such as silencing mechanisms for the M mtDNA at the transcriptional, post-transcriptional and/or post-translational levels. These hypotheses will necessitate additional studies in distantly-related DUI species that could possess different mechanisms of action to deal with heteroplasmy.

Affirming Life in the Face of Death: Ricoeur's Living Up to Death as a modern ars moriendi and a lesson for palliative care.

Science.gov (United States)

de Lange, Ds Frits

2014-11-01

In his posthumously published Living Up to Death Paul Ricoeur left an impressive testimony on what it means to live at a high old age with death approaching. In this article I present him as a teacher who reminds us of valuable lessons taught by patients in palliative care and their caretakers who accompany them on their way to death, and also as a guide in our search for a modern ars moriendi, after--what many at least experience as--the breakdown of traditional religious belief in a personal afterlife. These lessons can be summarized in the following theses. 'Living up to death, one cannot experience one's own death. Therefore, never consider someone dying as moribund'. 'Though everybody is alone in dying, nobody should die alone.' 'The preparation for death is an affirmation of life'. 'Life experienced as a gift can be given up'. The plausibility of the last thesis, however, may go beyond the confines of austere philosophical thinking.

'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.

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.

Death audits have been used to describe pediatric mortality in under-resourced settings, where record keeping is often a challenge. This information provides the cornerstone for the foundation of quality improvement initiatives. Malawi, located in sub-Saharan Africa, currently has an Under-5 mortality rate of 64/1000. Kamuzu Central Hospital, in the capital city Lilongwe, is a busy government referral hospital, which admits up to 3000 children per month. A study published in 2013 reported mortality rates as high as 9%. This is the first known audit of pediatric death files conducted at this hospital. A retrospective chart review on all pediatric deaths that occurred at Kamuzu Central Hospital (excluding deaths in the neonatal nursery) during a 13-month period was done using a standardized death audit form. A descriptive analysis was completed, including patient demographics, HIV and nutritional status, and cause of death. Modifiable factors were identified that may have contributed to mortality, including a lack of vital sign collection, poor documentation, and delays in the procurement or results of tests, studies, and specialist review. Seven hundred forty three total pediatric deaths were recorded and 700 deceased patient files were reviewed. The mortality rate by month ranged from a low of 2.2% to a high of 4.4%. Forty-four percent of deaths occurred within the first 24 h of admission, and 59% occurred within the first 48 h. The most common causes of death were malaria, malnutrition, HIV-related illnesses, and sepsis. The mortality rate for this pediatric referral center has dramatically decreased in the 6 years since the last published mortality data, but remains high. Areas identified for continued development include improved record keeping, improved patient assessment and monitoring, and more timely and reliable provision of testing and treatment. This study demonstrates that in low-resource settings, where reliable record keeping is often difficult

Full Text Available OBJECTIVES: A study of maternal death conducted to evaluate various factors responsible for maternal deaths. To identify complications in pregnancy, a childbirth which result in maternal death, and to identify opportunities for preventive intervention and understand the events leading to death; so that improving maternal health and reducing maternal mortality rate significantly. To analyze the causes and epidemiological amounts maternal mortality e.g. age parity, socioeconomic status and literacy. In order to reduce maternal mortality and to implement safe motherhood program and complications of pregnancy and to find out safe motherhood program. METHODS: The data collected was a retrograde by a proforma containing particulars of the diseased, detailed history and relatives were interviewed for additional information. The data collected was analysed. RESULTS: Maternal mortality rate in our own institution is 200/ 100,000 live births. Among 30 maternal deaths, 56% deaths (17 were among low socio - economic status, groups 60% deaths among unbooked 53.5% deaths more along illiterates evidenced by direct and indirect deaths about 25% of deaths were preventable. CONCLUSION: Maternal death is a great tragedy in the family life. It is crusade to know not just the medical cause of the death but the circumstances what makes these continued tragic death even more unacceptable is that deaths are largely preventable

We investigated the effect of fasting blood glucose and body mass index (BMI) at diagnosis on risk of breast cancer death for cases diagnosed in five Italian cancer registries in 2003-2005 and followed up to the end of 2008. For 1607 Italian women (≥15 years) with information on BMI or blood glucose or diabetes, we analysed the risk of breast cancer death in relation to glucose tertiles (≤84.0, 84.1-94.0, >94.0 mg/dl) plus diabetic and unspecified categories; BMI tertiles (≤23.4, 23.5-27.3, >27.3 kg/m(2), unspecified), stage (T1-3N0M0, T1-3N+M0 plus T4anyNM0, M1, unspecified), oestrogen (ER) and progesterone (PR) status (ER+PR+, ER-PR-, ER and PR unspecified, other), age, chemotherapy and endocrine therapy, using multiple regression models. Separate models for ER+PR+ and ER-PR- cases were also run. Patients often had T1-3N0M0, ER+PR+ cancers and received chemotherapy or endocrine therapy; only 6% were M1 and 17% ER-PR-. Diabetic patients were older and had more often high BMI (>27 kg/m(2)), ER-PR-, M1 cancers than other patients. For ER+PR+ cases, with adjustment for other variables, breast cancer mortality was higher in women with high BMI than those with BMI 23.5-27.3 kg/m(2) (hazard ratio (HR)=2.9, 95% confidence interval (CI) 1.2-6.9). Breast cancer mortality was also higher in women with high (>94 mg/dl) blood glucose compared to those with glucose 84.1-94.0mg/dl (HR=2.6, 95% CI 1.2-5.7). Our results provide evidence that in ER+PR+ patients, high blood glucose and high BMI are independently associated with increased risk of breast cancer death. Detection and correction of these factors in such patients may improve prognosis. Copyright © 2013 Elsevier Ltd. All rights reserved.

Death and consciousness--an overview of the mental and cognitive experience of death.

Science.gov (United States)

Parnia, Sam

2014-11-01

Advances in resuscitation science have indicated that, contrary to perception, death by cardiorespiratory criteria can no longer be considered a specific moment but rather a potentially reversible process that occurs after any severe illness or accident causes the heart, lungs, and brain to stop functioning. The resultant loss of vital signs of life (and life processes) is used to declare a specific time of death by physicians globally. When medical attempts are made to reverse this process, it is commonly referred to as cardiac arrest; however, when these attempts do not succeed or when attempts are not made, it is called death by cardiorespiratory criteria. Thus, biologically speaking, cardiac arrest and death by cardiorespiratory criteria are synonymous. While resuscitation science has provided novel opportunities to reverse death by cardiorespiratory criteria and treat the potentially devastating consequences of the resultant postresuscitation syndrome, it has also inadvertently provided intriguing insights into the likely mental and cognitive experience of death. Recollections reported by millions of people in relation to death, so-called out-of-body experiences (OBEs) or near-death experiences (NDEs), are often-discussed phenomena that are frequently considered hallucinatory or illusory in nature; however, objective studies on these experiences are limited. To date, many consistent themes corresponding to the likely experience of death have emerged, and studies have indicated that the scientifically imprecise terms of NDE and OBE may not be sufficient to describe the actual experience of death. While much remains to be discovered, the recalled experience surrounding death merits a genuine scientific investigation without prejudice. © 2014 New York Academy of Sciences.

In 2013, more than 57,000 persons died in the United States as a result of violence-related injuries. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) regarding violent deaths from 17 U.S. states for 2013. Results are reported by sex, age group, race/ethnicity, marital status, location of injury, method of injury, circumstances of injury, and other selected characteristics. 2013. NVDRS collects data from participating states regarding violent deaths obtained from death certificates, coroner/medical examiner reports, law enforcement reports, and secondary sources (e.g., child fatality review team data, supplemental homicide reports, hospital data, and crime laboratory data). This report includes data from 17 states that collected statewide data for 2013 (Alaska, Colorado, Georgia, Kentucky, Maryland, Massachusetts, North Carolina, New Jersey, New Mexico, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, Utah, Virginia, and Wisconsin). NVDRS collates documents for each death and links deaths that are related (e.g., multiple homicides, a homicide followed by a suicide, or multiple suicides) from a single incident. For 2013, a total of 18,765 fatal incidents involving 19,251 deaths were captured by NVDRS in the 17 states included in this report. The majority (66.2%) of deaths were suicides, followed by homicides (23.2%), deaths of undetermined intent (8.8%), deaths involving legal intervention (1.2%) (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force, excluding legal executions), and unintentional firearm deaths (Revision [ICD-10] and does not denote the lawfulness or legality of the circumstances surrounding a death caused by law enforcement.) Suicides occurred at higher rates among males, non-Hispanic whites, American Indian/Alaska Natives, persons aged 45-64 years, and males aged ≥75 years. Suicides were preceded primarily by a mental health, intimate partner, or physical

The Syrian armed conflict has been ongoing since 2011 and has already caused thousands of deaths. The analysis of death tolls helps to understand the dynamics of the conflict and to better allocate resources and aid to the affected areas. In this article, we use information on the daily number of deaths to study temporal and spatial correlations in the data, and exploit this information to forecast events of deaths. We found that the number of violent deaths per day in Syria varies more widely than that in England in which non-violent deaths dominate. We have identified strong positive auto-correlations in Syrian cities and non-trivial cross-correlations across some of them. The results indicate synchronization in the number of deaths at different times and locations, suggesting respectively that local attacks are followed by more attacks at subsequent days and that coordinated attacks may also take place across different locations. Thus the analysis of high temporal resolution data across multiple cities makes it possible to infer attack strategies, warn potential occurrence of future events, and hopefully avoid further deaths.

Full Text Available Sudden cardiac death is one of the most common cause of mortality worldwide. Despite significant advances in the medical science, there is little improvement in the sudden cardiac death related mortality. Coronary artery disease is the most common etiology behind sudden cardiac death, in the above 40 years population. Even in the apparently healthy population, there is a small percentage of patients dying from sudden cardiac death. Given the large denominator, this small percentage contributes to the largest burden of sudden cardiac death. Identification of this at risk group among the apparently healthy individual is a great challenge for the medical fraternity. This article looks into the causes and methods of preventing SCD and at some of the Indian data. Details of Brugada syndrome, Long QT syndrome, Genetics of SCD are discussed. Recent guidelines on many of these causes are summarised.

We investigated the hypothesis that high Ca 2+ influx during traumatic brain injury induces the activation of the caspase-1 enzyme, which triggers neuroinflammation and cell apoptosis in a cell culture model of neuronal stretch injury and an in vivo model of fluid percussion injury (FPI). We first established that stretch injury causes a rapid increase in the intracellular Ca 2+ level, which activates interleukin-converting enzyme caspase-1. The increase in the intracellular Ca 2+ level and subsequent caspase-1 activation culminates into neuroinflammation via the maturation of IL-1β. Further, we analyzed caspase-1-mediated apoptosis by TUNEL staining and PARP western blotting. The voltage-gated sodium channel blocker, tetrodotoxin, mitigated the stretch injury-induced neuroinflammation and subsequent apoptosis by blocking Ca 2+ influx during the injury. The effect of tetrodotoxin was similar to the caspase-1 inhibitor, zYVAD-fmk, in neuronal culture. To validate the in vitro results, we demonstrated an increase in caspase-1 activity, neuroinflammation and neurodegeneration in fluid percussion-injured animals. Our data suggest that neuronal injury/traumatic brain injury (TBI) can induce a high influx of Ca 2+ to the cells that cause neuroinflammation and cell death by activating caspase-1, IL-1β, and intrinsic apoptotic pathways. We conclude that excess IL-1β production and cell death may contribute to neuronal dysfunction and cognitive impairment associated with TBI.

Death with dignity

Science.gov (United States)

Allmark, P.

2002-01-01

The purpose of this article is to develop a conception of death with dignity and to examine whether it is vulnerable to the sort of criticisms that have been made of other conceptions. In this conception "death" is taken to apply to the process of dying; "dignity" is taken to be something that attaches to people because of their personal qualities. In particular, someone lives with dignity if they live well (in accordance with reason, as Aristotle would see it). It follows that health care professionals cannot confer on patients either dignity or death with dignity. They can, however, attempt to ensure that the patient dies without indignity. Indignities are affronts to human dignity, and include such things as serious pain and the exclusion of patients from involvement in decisions about their lives and deaths. This fairly modest conception of death with dignity avoids the traps of being overly subjective or of viewing the sick and helpless as "undignified". PMID:12161582

Eyelid closure at death

Full Text Available Aim: To observe the incidence of full or partial eyelid closure at death. Materials and Methods: The presence of ptosis was recorded in 100 consecutive hospice patient deaths. Results: Majority (63% of the patients died with their eyes fully closed, however, 37% had bilateral ptosis at death, with incomplete eye closure. In this study, central nervous system tumor involvement and/or acute hepatic encephalopathy appeared to be pre-mortem risk factors of bilateral ptosis at death. Conclusion: Organicity and not psychogenicity is, therefore, the likely etiology of failure of full eyelid closure at death.

psychology or Kübler-Ross’ theory about death stages. The complex concerns might be explained using Martin Heidegger’s phenomenological thinking. We aimed to illuminate dying patients´ existential concerns about the impending death through a descriptive analysis of semi-structured interviews with 17 cancer...... patients in Danish hospices. The main findings demonstrated how the patients faced the forthcoming death without being anxious of death but sorrowful about leaving life. Furthermore, patients expressed that they avoided thinking about death. However, some had reconstructed specific and positive ideas about...... afterlife and made accurate decisions for practical aspects of their death. The patients wished to focus on positive aspects in their daily life at hospice. It hereby seems important to have ongoing reflections and to include different theoretical perspectives when providing existential support to dying...

Unintentional injuries are the leading cause of death in children around the world and are an under-recognized public health problem in the United States. The purpose of this study was to highlight the nature of the problem in South Dakota and outline interventions that have been successful in reducing childhood injuries in other states. This quantitative retrospective study examined mortality files in South Dakota for children birth to 19 years of age who died between January 1, 2000 to December 28, 2007. Although the number of deaths declined considerably from 2006 to 2007, South Dakota had the second-highest rate in the nation of childhood unintentional injury deaths from all causes between 2000-2005. The majority of deaths occurred in males and were associated with transportation-related deaths. Suffocation was the leading cause of death for newborns to age 1 year. Childhood accidental death in South Dakota is clearly a critical public health problem. Intervention efforts to reduce deaths from unintentional injuries amongst children should be targeted as the leading causes of accidental death for specific age groups and American Indian youth. Physicians, health educators and policymakers must play a role in prevention targeting the high-risk groups in addition to advocating for policy changes to protect childhood safety. More stringent child restraint laws, graduated driving laws, smoking cessation programs for parents, creation of safer sleep environments and further investigation of why a high proportion of American Indian children die accidentally in South Dakota are all warranted.

Tuberous sclerosis complex (TSC) is an autosomal dominant syndrome associated with tumors of the brain, heart, kidney, and lung. The TSC protein complex inhibits the mammalian or mechanistic target of rapamycin complex 1 (mTORC1). Inhibitors of mTORC1, including rapamycin, induce a cytostatic response in TSC tumors, resulting in temporary disease stabilization and prompt regrowth when treatment is stopped. The lack of TSC-specific cytotoxic therapies represents an important unmet clinical need. Using a high-throughput chemical screen in TSC2-deficient, patient-derived cells, we identified a series of molecules antagonized by rapamycin and therefore selective for cells with mTORC1 hyperactivity. In particular, the cell-permeable alkaloid chelerythrine induced reactive oxygen species (ROS) and depleted glutathione (GSH) selectively in TSC2-null cells based on metabolic profiling. N-acetylcysteine or GSH cotreatment protected TSC2-null cells from chelerythrine's effects, indicating that chelerythrine-induced cell death is ROS dependent. Induction of heme-oxygenase-1 (HMOX1/HO-1) with hemin also blocked chelerythrine-induced cell death. In vivo, chelerythrine inhibited the growth of TSC2-null xenograft tumors with no evidence of systemic toxicity with daily treatment over an extended period of time. This study reports the results of a bioactive compound screen and the identification of a potential lead candidate that acts via a novel oxidative stress-dependent mechanism to selectively induce necroptosis in TSC2-deficient tumors. This study demonstrates that TSC2-deficient tumor cells are hypersensitive to oxidative stress-dependent cell death, and provide critical proof of concept that TSC2-deficient cells can be therapeutically targeted without the use of a rapalog to induce a cell death response. ©2014 American Association for Cancer Research.

Despite the wish of the Japanese people to spend their final moments at home, the percentage of deaths at home among elderly is decreasing. Moreover, large variations in this rate were observed over the country. The present ecological study analyzed the relationship between the percentage of deaths at home for decedents aged 70 and over, and demographic, medical and socioeconomic characteristics. The data published in 1990 by the Japanese National Government were analyzed by correlation, principal-component, and multiple linear regression analyses. The results showed that the percentage of deaths at home for decedents aged 70 and over was positively associated with the number of persons per household, and the area of floor space per house. The divorce rate, the national tax per capita, and the mean length of hospitalization for stroke showed a negative association with the percentage of deaths at home. In the prefectures where the crude death rates of stroke and senility were high, elderly were more likely to die at home. These results suggested the importance of the number of family caregivers, and the housing conditions for terminal care at home. This research may lead to improve home medical assistance which is still underdeveloped in Japan.

The Janus face of death receptor signalling during tumour immunoediting.

Directory of Open Access Journals (Sweden)

Eimear O' Reilly

2016-10-01

Full Text Available Cancer immune-surveillance is essential for the inhibition of carcinogenesis. Malignantly transformed cells can be recognised by both the innate and adaptive immune systems through different mechanisms. Immune effector cells induce extrinsic cell death in the identified tumour cells by expressing death ligand cytokines of the tumour necrosis factor ligand family. However, some tumour cells can escape immune elimination and progress. Acquisition of resistance to the death-ligand induced apoptotic pathway can be obtained through cleavage of effector-cell expressed death-ligands into a poorly active form, mutations or silencing of the death receptors or overexpression of decoy receptors and pro-survival proteins. Although the immune system is highly effective in the elimination of malignantly transformed cells, abnormal/ dysfunctional death-ligand signalling curbs its cytotoxicity. Moreover, death receptors can also transmit pro-survival and pro-migratory signals. Consequently, dysfunctional death receptor-mediated apoptosis/necroptosis signalling does not only give a passive resistance against cell death, but actively drives tumour cell motility, invasion and contributes to consequent metastasis. This dual contribution of the death ligand-death receptor signalling in both the early, elimination phase and then in the late, escape phase of the tumour immunoediting process is discussed in this review. Death receptor agonists still hold potential for cancer therapy since they can execute the tumour-eliminating immune-effector function even in the absence of activation of the immune system against the tumour. The opportunities and challenges of developing death receptor agonists into effective cancer therapeutics are also discussed.

Making death 'good': instructional tales for dying in newspaper accounts of Jade Goody's death.

Frith, Hannah; Raisborough, Jayne; Klein, Orly

2013-03-01

Facilitating a 'good' death is a central goal for hospices and palliative care organisations. The key features of such a death include an acceptance of death, an open awareness of and communication about death, the settling of practical and interpersonal business, the reduction of suffering and pain, and the enhancement of autonomy, choice and control. Yet deaths are inherently neither good nor bad; they require cultural labour to be 'made over' as good. Drawing on media accounts of the controversial death of UK reality television star Jade Goody, and building on existing analyses of her death, we examine how cultural discourses actively work to construct deaths as good or bad and to position the dying and those witnessing their death as morally accountable. By constructing Goody as bravely breaking social taboos by openly acknowledging death, by contextualising her dying as occurring at the end of a life well lived and by emphasising biographical continuity and agency, newspaper accounts serve to position themselves as educative rather than exploitative, and readers as information-seekers rather than ghoulishly voyeuristic. We argue that popular culture offers moral instruction in dying well which resonates with the messages from palliative care. © 2012 The Authors.

Full Text Available The present study is aimed at examining the level of death anxiety and the sex-related differences among old-aged Iranian individuals sample to compare the old-aged persons with young college students and to explore the psychometric properties of the Arabic Scale of Death Anxiety (ASDA factors in old-aged sample. A sample of 146 volunteer Iranian individuals took part in the study. The mean ages were 68.58 (SD = 7.10, men 68.81 (SD = 7.44 and women 68.28 (SD = 6.76, respectively. The mean score of the ASDA was 51.09 (SD = 20.19. Cronbach’s alpha of the ASDA was found to be high (0.94; and Spearman-Brown coefficient was 0.92. Women had a significantly higher mean total score on the ASDA. Old-aged individuals had a significantly higher mean ASDA total score than younger college students (M age = 25.77. The factor analysis of the ASDA items yielded three factors accounting for 67.88% of the total variance labeled (F1 fear of dead people and tombs; (F2 fear of lethal disease and postmortem events; and (F3 death fear. These factors were highly replicable with previous factors extracted from a middle-aged Kuwaiti sample. On the basis of the present results, there are the following three general conclusions: death anxiety is not significantly correlated with age; the sex-related differences on death anxiety are striking in the Iranian samples; and the ASDA has a highly replicable factor structure among two Iranian and Arab countries.

Full Text Available Intravenous haloperidol has been associated with torsades de pointes (TdP. These two sudden deaths were probable adverse drug reactions (ADRs following intramuscular (IM antipsychotics. The autopsies described lack of heart pathology and were highly compatible with the possibility of TdP in the absence of risk factors other than the accumulation of antipsychotics with a high serum peak after the last injection, leading to death within hours. The first case was a 27-year-old African-American male with schizophrenia but no medical issues. His death was probably caused by repeated IM haloperidol injections of 10 mg (totaling 35 mg in 2 days. The second case involves a 42-year-old African-American female with metabolic syndrome. Her probable cause of death was the last ziprasidone IM injection of 20 mg in addition to (1 three extra haloperidol doses (2 hours before the ziprasidone injection, 5 mg oral haloperidol; approximately 21 hours earlier, 5 mg oral haloperidol; and 2 days prior, one 10 mg IM haloperidol injection, (2 10 mg/day of scheduled oral haloperidol for 6 days before death, and (3 a long-acting paliperidone injection of 156 mg 18 days before death. The study of haloperidol glucuronidation and its impairment in some African-Americans is urgently recommended.

In light of an emerging epidemic identified in the United States and Canada, to identify trends in fatal drug toxicity involving oxycodone and the demographic characteristics and indicators of socioeconomic disadvantage of the deceased. Population-based observational study in Victoria, Australia. Decedents whose death was reported to the Victorian Coroner between 2000 and 2009 and where oxycodone was detected. Association between supply of oxycodone and deaths. Demographic characteristics of decedents. Rate ratios of the rural or metropolitan location and socioeconomic indicators of disadvantage of the deceased. Supply to Victoria has increased nine-fold from 7.5 mg per capita in 2000 to 67.5 mg per capita in 2009. Detection of oxycodone in deaths reported to the Victorian Coroner has increased from 4 (0.08/100,000 population) in 2000 to 97 (1.78/100,000 population) in 2009-a 21-fold increase in deaths. Of the 320 cases described, 53.8% (172) were the result of drug toxicity. Of these, 52.3% were unintentional and 19.8% intentional self-harm; the remaining 27.9% are either still under investigation by the coroner or intent is unknown. Drug toxicity deaths were overrepresented in both rural areas and areas indexed with high levels of disadvantage. The substantial increase in the number of deaths involving oxycodone is strongly and significantly associated with the increase in supply. Most drug toxicity deaths involving oxycodone were unintentional. This newly identified trend in fatalities in Victoria supports concerns that a pattern of increasing deaths involving oxycodone is emerging globally.

Implantable defibrillators (ICDs) prevent sudden cardiac death. With declining health, ICD therapy may prolong death and expose the patient to unnecessary pain and anxiety. Few studies have addressed end of life care in ICD patients. The objective of this study was to investigate end of life in ICD patients, with respect to location of death; duration between do-not-resuscitate (DNR)-orders and deactivation of ICD therapy or DNR and time of death. A descriptive analysis of 65 deceased ICD patients, all whom had a written DNR-order before death, is presented. The majority (86%) was treated in hospitals, mainly (63%) university hospitals, and many (33%) in cardiology wards. Despite DNR-order, ICD shock therapy was active in 51% of all patients. In those with therapy deactivated at death, therapy deactivation was carried out two days or more after DNR-order in more than a third (38%). The time from DNR decision to death in patients with therapy active had a median of four days (IQR 1-38). During the last 24h of life, 24% of the patients experienced shock treatment. The majority of ICD patients with a DNR-order were treated in university hospitals. More than half still had shock treatment active at time of death with a median of four days or more between DNR decision and death. Patients with therapy deactivated, two days or more elapsed in more than a third from DNR decision to deactivation of therapy, exposing patients to a high risk of painful shocks before death.

Brain death revisited: it is not 'complete death' according to Islamic sources.

Science.gov (United States)

Bedir, Ahmet; Aksoy, Sahin

2011-05-01

Concepts, such as death, life and spirit cannot be known in their quintessential nature, but can be defined in accordance with their effects. In fact, those who think within the mode of pragmatism and Cartesian logic have ignored the metaphysical aspects of these terms. According to Islam, the entity that moves the body is named the soul. And the aliment of the soul is air. Cessation of breathing means leaving of the soul from the body. Those who agree on the diagnosis of brain death may not able to agree unanimously on the rules that lay down such diagnosis. That is to say, there are a heap of suspicions regarding the diagnosis of brain death, and these suspicions are on the increase. In fact, Islamic jurisprudence does not put provisions, decisions on suspicious grounds. By virtue of these facts, it can be asserted that brain death is not absolute death according to Islamic sources; for in the patients diagnosed with brain death the soul still has not abandoned the body. Therefore, these patients suffer in every operation performed on them.

[Distribution of and changes in Danish traffic deaths].

Bjerre, Johannes; Kirkebjerg, Peer Gregersen; Larsen, Lars Binderup

2006-05-01

Traffic accidents were the primary cause of death for Danes aged 15 to 24 years in 1999; per million inhabitants, that figure was 62% higher than in Great Britain. Reduction to the level in Great Britain would have reduced the number killed in traffic accidents in Denmark in 2002 from 465 to 289. The data used are from StatBank Denmark, the Danish Road Directorate and the Danish Transport Research Institute. The number of traffic deaths per billion kilometers driven was 57% higher in 1994 than in 2001. Those aged 65 and over had the largest decrease, with 67% fewer traffic deaths. Per billion kilometers driven, rural roads had around twice the number of traffic deaths as city streets and motorways. The geographic distribution showed few traffic deaths in the capital, Copenhagen, while the rest of the country had up to twice the number per 100,000 inhabitants from 1997 to 2002. Car drivers were well protected by seat belts, while people who were walking or on a motorcycle had high casualty rates per billion kilometers driven. 29% of the traffic deaths in Denmark in 2002 were registered as alcohol-related, while only 1% of drivers overall were influenced by alcohol. Men had twice the risk of traffic death compared with women per kilometer driven. Men were convicted in 93% of cases involving illegal blood alcohol level and 84% of cases involving other traffic offences. The greatest potential for reduction of traffic deaths seems to be traffic behaviour; females' behaviour, with rare drunk driving and few convictions for traffic offences, seems rational. If all drivers adhered to women's traffic behaviour, the number of road deaths in 1999 could have been reduced by 169, equivalent to 30%.

Trends in compensation for deaths from occupational cancer in Canada: a descriptive study.

Del Bianco, Ann; Demers, Paul A

2013-09-01

Occupational cancer is the leading cause of work-related deaths, yet it is often unrecognized and under reported, and associated claims for compensation go unfiled. We sought to examine trends in deaths from occupational cancer, high-risk industries and exposures, and commonly compensated categories of occupational cancers. In addition, we compared deaths from occupational lung cancer for which compensation had been given with total deaths from lung cancer. We used data from the Association of Workers' Compensation Boards of Canada pertaining to the nature and source of the injury or disease and the industry in which it occurred (by jurisdiction) to describe trends in compensated claims for deaths from occupational cancer in Canada for the period 1997-2010. We used data published by the Canadian Cancer Society in Canadian Cancer Statistics to compare compensated occupational lung cancer deaths with total estimated lung cancer deaths for the period between 2006 and 2010. Compensated claims for deaths from occupational cancer have increased in recent years and surpassed those for traumatic injuries and disorders in Canada, particularly in Ontario. Between 1997 and 2010, one-half of all compensated deaths from occupational cancer in Canada were from Ontario. High-risk industries for occupational cancer include manufacturing, construction, mining and, more recently, government services. Deaths from lung cancer and mesothelioma comprise most of the compensated claims for deaths from occupational cancer in Ontario and Canada. These diseases are usually the result of asbestos exposure. The burden of other occupational carcinogens is not reflected in claims data. Although the number of accepted claims for deaths from occupational cancers has increased in recent years, these claims likely only represent a fraction of the true burden of this problem. Increased education of patients, workers at high risk of exposure and health care providers is needed to ensure that people

This report presents final 2012 data on the 10 leading causes of death in the United States by age, sex, race, and Hispanic origin. Leading causes of infant, neonatal, and postneonatal death are also presented. This report supplements "Deaths: Final Data for 2012," the National Center for Health Statistics' annual report of final mortality statistics. Data in this report are based on information from all death certificates filed in the 50 states and the District of Columbia in 2012. Causes of death classified by the International Classification of Diseases, Tenth Revision (ICD-10) are ranked according to the number of deaths assigned to rankable causes. Cause-of-death statistics are based on the underlying cause of death. In 2012, the 10 leading causes of death were, in rank order: Diseases of heart; Malignant neoplasms; Chronic lower respiratory diseases; Cerebrovascular diseases; Accidents (unintentional injuries); Alzheimer's disease; Diabetes mellitus; Influenza and pneumonia; Nephritis, nephrotic syndrome and nephrosis; and Intentional self-harm (suicide). These causes accounted for 74% of all deaths occurring in the United States. Differences in the rankings are evident by age, sex, race, and Hispanic origin. Leading causes of infant death for 2012 were, in rank order: Congenital malformations, deformations and chromosomal abnormalities; Disorders related to short gestation and low birth weight, not elsewhere classified; Sudden infant death syndrome; Newborn affected by maternal complications of pregnancy; Accidents (unintentional injuries); Newborn affected by complications of placenta, cord and membranes; Bacterial sepsis of newborn; Respiratory distress of newborn; Diseases of the circulatory system; and Neonatal hemorrhage. Important variations in the leading causes of infant death are noted for the neonatal and postneonatal periods.

Dokov, William

2009-02-01

Fatal high-voltage injuries present a problem which has not yet been studied sufficiently in the context of interaction between the human body and electricity, as a technical, anthropogenic and natural phenomenon. The forensic medicine records of 291 cases of death caused by high-voltage current for a 41-year-long period (1965-2006) were examined in retrospect. The descriptive statistical analyses were made using the SPSS 11.0 software. Death was found to result most commonly from contact between the deceased and elements of the power transmission and distribution grid: (41.24%), and from the action of lightning: (32.3%), the difference in their relative share being insignificant. Much more rarely, death was due to contact with construction and repair electrical devices: (7.56%), or with elements of the power transport railway infrastructure: (6.87%). Death resulting from contact with agricultural electrical devices was only occasional: (0.68%). The victims' average age was 36.19 years. Our analysis indicates that the relative share (43.98%) of the victims is the highest in the age period between 25 and 44. The ratio between women and men is 1:21.38.

The analysis of Sudden Infant Death Syndrome in Poland

Directory of Open Access Journals (Sweden)

Anna Lewandowska

2017-05-01

Full Text Available Introduction: Sudden Infant Death Syndrome is defined in literature similarly as a sudden and unexpected death of an infant occurring during sleep and, at the same time, causes of which cannot be explained based on anamnesis, circumstances of death or comprehensive post-mortem examinations. Sudden Infant Death Syndrome is considered to be the most frequent cause of death among infants in the developed countries. Incidence of SIDS in the whole world ranges from about 0.1 to 6.0/1,000 live births. As much as 90% concerns deaths in the first year of life of a child, whereas 70% stands for deaths for which the cause remains unknown. In SIDS, about 90% of cases concern children under 1 year old and, in particular, at the age of between 2 and 4 months. The aim: The aim of the study was to present the most significant aspects of SIDS as well as description and analysis of risk factors for occurrence of sudden infant death syndrome based on statistical data. Materials and methods: For the purpose of the study, the secondary data analysis and desk research technique have been applied. The analysis is based on statistical data from the time period 2009-2014 released by the Central Statistical Office of Poland. Results: In 2009-2014, the highest number of deaths of infants and new-borns was reported in 2009 with the number being as high as 2,327. In the following years, the number of deaths of new-borns and infants systematically decreased. In 2010 it was 2,057 and in 2011 – 1,836, in 2012 – 1,791, in 2013 – 1,684, and in 2014 – 1,583. The highest number of deaths of boys was reported in 2009 – 1,298, while the number of deaths of girls in that year, although it was the highest in the analysed period, was lower – 1,029. Conclusions: cases of death were more frequent among boys rather than girls. The highest number of deaths was reported among infants under the age of one month and the number decreased with an increasing infants’ age. More

Magnetic resonance imaging (MRI) was undertaken for two patients who suffered from severe cerebrovascular diseases and were clinically brain dead. The MRI system we used was Resona (Yokogawa Medical Systems, superconductive system 0.5 T) and the CT apparatus was Toshiba TCT-300. Initial CT and MRI were undertaken as soon as possible after admission, and repeated sequentially. After diagnosis of brain death, we performed angiography to determine cerebral circulatory arrest, and MRI obtained at the same time was compared with the angiogram and CT. Case 1 was a 77-year-old man who was admitted in an unconscious state. CT and MRI on the second day after hospitalization revealed cerebellar infarction. He was diagnosed as brain dead on day 4. Case 2 was a 35-year-old man. When he was transferred to our hospital, he was in cardiorespiratory arrested. Cardiac resuscitation was successful but no spontaneous respiration appeared. CT and MRI on admission revealed right intracerebral hemorrhage. Angiography revealed cessation of contrast medium in intracranial vessels in both of the patients. We found no 'flow signal void sign' in the bilateral internal carotid and basilar arteries on MRI images in both cases after brain death. MRI, showing us the anatomical changes of the brain, clearly revealed brain herniations, even though only nuclear findings of 'brain tamponade' were seen on CT. But in Case 1, we could not see the infarct lesions in the cerebellum on MR images obtained after brain death. This phenomenon was caused by the whole brain ischemia masking the initial ischemic lesions. We concluded that MRI was useful not only the anatomical display of lesions and brain herniation with high contrast resolution but for obtaining information on cerebral circulation of brain death.

This report presents final 2011 data on the 10 leading causes of death in the United States by age, sex, race, and Hispanic origin. Leading causes of infant, neonatal, and postneonatal death are also presented. This report supplements ‘‘Deaths: Final Data for 2011,’’ the National Center for Health Statistics’ annual report of final mortality statistics. Data in this report are based on information from all death certificates filed in the 50 states and the District of Columbia in 2011. Causes of death classified by the International Classification of Diseases, 10th Revision (ICD–10) are ranked according to the number of deaths assigned to rankable causes. Cause-of-death statistics are based on the underlying cause of death. In 2011, the 10 leading causes of death were, in rank order: Diseases of heart; Malignant neoplasms; Chronic lower respiratory diseases; Cerebrovascular diseases; Accidents (unintentional injuries); Alzheimer’s disease; Diabetes mellitus; Influenza and pneumonia; Nephritis, nephrotic syndrome and nephrosis; and Intentional self-harm (suicide). They accounted for 74% of all deaths occurring in the United States. Differences in the rankings are evident by age, sex, race, and Hispanic origin. Leading causes of infant death for 2011 were, in rank order: Congenital malformations, deformations and chromosomal abnormalities; Disorders related to short gestation and low birth weight, not elsewhere classified; Sudden infant death syndrome; Newborn affected by maternal complications of pregnancy; Accidents (unintentional injuries); Newborn affected by complications of placenta, cord and membranes; Bacterial sepsis of newborn; Respiratory distress of newborn; Diseases of the circulatory system; and Neonatal hemorrhage.

Certified causes of death in patients with mesothelioma in South East England

Directory of Open Access Journals (Sweden)

2009-01-01

Full Text Available Abstract Background Mesothelioma is a highly fatal cancer that is caused by exposure to asbestos fibres. In many populations, the occurrence of mesothelioma is monitored with the use of mortality data from death certification. We examine certified causes of death of patients who have been diagnosed with mesothelioma, and assess the validity of death certification data as a proxy for mesothelioma incidence. Methods We extracted mesothelioma registrations in the South East of England area between 2000 and 2004 from the Thames Cancer Registry database. We retained for analysis 2200 patients who had died at the time of analysis, after having excluded seven dead cases where the causes of death were not known to the cancer registry. The 2200 deaths were classified hierarchically to identify (1 mesothelioma deaths, (2 deaths certified as lung cancer deaths or (3 deaths from unspecified cancer, and (4 deaths from other causes. Results 87% of the patients had mesothelioma mentioned on the death certificate. 6% had no mention of mesothelioma but included lung cancer as a cause of death. Another 6% had no mention of mesothelioma or lung cancer, but included an unspecified cancer as a cause of death. Lastly, 2% had other causes of death specified on the death certificate. Conclusion This analysis suggests that official mortality data may underestimate the true occurrence of mesothelioma by around 10%.

[Deaths in hotels].

There are no verified statistics about deaths occurring in hotels, and only a few cases have been described in the literature. A recent case induced us to conduct a systematic search for deaths in hotels in the autopsy reports of the Institute of Legal Medicine in Giessen for the period from 1968 to 2009. This search yielded 22 evaluable cases in which persons had been found dead or had died in hotels. Data evaluated in the study were sex and age of the deceased, reason for the stay in the hotel and cause of death. Among the deaths, 18 were males and 4 females and the average age was 41 and 40 years respectively. 6 of the male guests had died from a natural and 10 from a non-natural cause. In the remaining two cases, the cause of death could not be determined, but as there was no evidence that another party had been involved, the cases were not further investigated. Of the 4 female guests, 3 had died of a natural cause; in one case, the cause of death remained unclear even after morphological and toxicological investigations. Surprisingly, a third of the men were found to be temporarily living in hotels due to social circumstances. This was not true for any of the women. Our retrospective analysis is based on a comparatively small number of deaths in what were mostly hotels in small to medium-sized towns. Interestingly, the gender ratio of 18:4 for deceased men and women was significantly higher than the usual gender ratio of 2:1 found for forensic autopsies. To be able to draw further conclusions, a greater number of cases would have to be analysed, for example by recruiting additional case files from other institutes of legal medicine. This would also open up the option of investigating possible regional variations.

Referring to our experience with post-mortem computed tomography (CT), many hypothermic death cases presented a lack of increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and urine retention in the bladder. Thus we evaluated the diagnostic performance of post-mortem CT on hypothermic death based on the above-mentioned three findings. Twenty-four hypothermic death subjects and 53 non-hypothermic death subjects were examined. Two radiologists assessed the presence or lack of an increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and measured urine volume in the bladder. Pearson's chi-square test and Mann–Whitney U-test were used to assess the relationship between the three findings and hypothermic death. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the diagnosis were also calculated. Lack of an increase in lung-field concentration and blood clotting in the heart, thoracic aorta or pulmonary artery were significantly associated with hypothermic death (p = 0.0007, p < 0.0001, respectively). The hypothermic death cases had significantly more urine in the bladder than the non-hypothermic death cases (p = 0.0011). Regarding the diagnostic performance with all three findings, the sensitivity was 29.2% but the specificity was 100%. These three findings were more common in hypothermic death cases. Although the sensitivity was low, these findings will assist forensic physicians in diagnosing hypothermic death since the specificity was high.

This exploratory study investigated factors associated with the wish to hasten death among a sample of terminally ill cancer patients. Semi-structured interviews conducted on a total of 72 hospice and home palliative care patients were subjected to qualitative analysis using QSR-NUDIST. The main themes to emerge suggested that patients with a high wish to hasten death had greater concerns with physical symptoms and psychological suffering, perceived themselves to be more of a burden to others, and experienced higher levels of demoralization, while also reporting less confidence in symptom control, fewer social supports, less satisfaction with life experiences and fewer religious beliefs when compared with patients who had a moderate or no wish to hasten death. The implications of these findings will be discussed.

Purpose: Currently, no clinical imaging modality is used routinely to assess tumor response to cancer therapies within hours to days of the delivery of treatment. Here, the authors demonstrate the efficacy of ultrasound at a clinically relevant frequency to quantitatively detect changes in tumors in response to cancer therapies using preclinical mouse models.Methods: Conventional low-frequency and corresponding high-frequency ultrasound (ranging from 4 to 28 MHz) were used along with quantitative spectroscopic and signal envelope statistical analyses on data obtained from xenograft tumors treated with chemotherapy, x-ray radiation, as well as a novel vascular targeting microbubble therapy.Results: Ultrasound-based spectroscopic biomarkers indicated significant changes in cell-death associated parameters in responsive tumors. Specifically changes in the midband fit, spectral slope, and 0-MHz intercept biomarkers were investigated for different types of treatment and demonstrated cell-death related changes. The midband fit and 0-MHz intercept biomarker derived from low-frequency data demonstrated increases ranging approximately from 0 to 6 dBr and 0 to 8 dBr, respectively, depending on treatments administrated. These data paralleled results observed for high-frequency ultrasound data. Statistical analysis of ultrasound signal envelope was performed as an alternative method to obtain histogram-based biomarkers and provided confirmatory results. Histological analysis of tumor specimens indicated up to 61% cell death present in the tumors depending on treatments administered, consistent with quantitative ultrasound findings indicating cell death. Ultrasound-based spectroscopic biomarkers demonstrated a good correlation with histological morphological findings indicative of cell death (r 2 = 0.71, 0.82; p < 0.001).Conclusions: In summary, the results provide preclinical evidence, for the first time, that quantitative ultrasound used at a clinically relevant frequency, in

According to a widely accepted belief, we cannot know our own death-death means 'nothing' to us. At first sight, the meaning of 'nothing' just implies the negation or absence of 'something'. Death then simply refers to the negation or absence of life. As a consequence, however, death has no meaning

GSK-3β Inhibition Attenuates LPS-Induced Death but Aggravates Radiation-Induced Death via Down-Regulation of IL-6

Directory of Open Access Journals (Sweden)

Bailong Li

2013-12-01

Full Text Available Background: Exposure of high dose ionizing radiation is lethal. Signal pathways involved in radiation biology reaction still remain illdefined. Lipopolysaccharides (LPS, the ligands of Toll-like receptor 4(TLR4, could elicit strong immune responses. Glycogen synthase kinase-3β(GSK-3β promotes the production of inflammatory molecules and cell migration. Inhibition of GSK-3β provides protection against inflammation in animal models. The aim of the study was to investigate role of GSK-3β in LPS shock and ionizing radiation. Methods: WT or IL-6-/-mice or cells were pretreated with SB216763, a GSK-3β inhibitor, and survival of the mice was determined. Cell viability was assayed by Cell Counting Kit. Apoptosis was assayed by Annexin V-PI double staining. Serum concentrations of IL-6 and TNF-α were determined by ELISA. Results: SB216763 attenuated LPS induced mice or cell death but aggravated radiation induced mice or cell death. SB216763 reduced IL-6, but not TNF-α levels in vivo. IL-6-/- mice were more resistant to LPS-induced death but less resistant to radiation-induced death than wild type mice. Conclusions: Inhibition of GSK-3β conferred resistance to LPS shock but fostered death induced by ionizing radiation. Inhibition of GSK-3β was effective by reducing IL-6.

Interbasin flow revisited: The contribution of local recharge to high-discharge springs, Death Valley, CA

Science.gov (United States)

Anderson, Katherine; Nelson, Stephen; Mayo, Alan; Tingey, David

2006-05-01

Springs in the Furnace Creek area (Texas, Travertine, and Nevares Springs) of Death Valley National Park exhibit high discharge rates and depleted δ18O VSMOW (˜-13‰) and δD VSMOW (˜-102‰) values. Isotopic depletion of this magnitude and large spring fluxes (˜10,000 L/min) suggests that modern local recharge in the arid Furnace Creek drainage cannot be responsible for spring fluxes. An alternate explanation, interbasin flow, is difficult to envisage due to the stratigraphic and structural relationships of bedrock in intervening ranges, although it is the most common conceptual model for Furnace Creek spring flows. High-flux springs at Furnace Creek nonetheless respond modestly to modern climate in terms of discharge rate and isotopic composition. Hydrographs show a climate response and variations in time-series stable isotope data of widely spaced springs track one another. Small, but measurable quantities of tritium (water for these springs may be, there appears to be a subtle, but recent climatic influence. Estimates of flow at nearby mountain springs produce discharge rates per square kilometer of catchment that, by analogy, could support from 20 to 300% of the flow at large Death Valley springs under the current climate. Yet, 14C model ages suggest valley-bottom springs at Furnace Creek (5500-14,500 yr) contain a large component of older water, suggesting that much of the water was recharged during a pluvial period (Younger Dryas?) when net infiltration would have been much higher and isotopically depleted. 14C model ages are also of similar age, or younger, than many 'up gradient' waters, rather than being older as would be expected for interbasin flow. Chemical evolution models of solutes are consistent with both local recharge and interbasin transfer from Ash Meadows. However, when considered with isotopic constraints, interbasin flow becomes obviously untenable. Estimates of the thickness of alluvium and semi-consolidated Tertiary units in the

Brain Death in Islamic Jurisprudence

A Nikzad

2016-07-01

Full Text Available BACKGROUND AND OBJECTIVE: In today's world, Islamic jurisprudence encounters  new issues. One of the areas where jurisprudence gets involved is the issues concerned with brain death, whether brain death in jurisprudence and Islamic law is considered the end of life. In this study, brain death was discussed from the Shiite jurisprudence perspective and also the opinions of the specialists are taken into account. METHODS: This study is designed based on library collection and review of the literature in the field of brain death. Also, Quranic verses, hadiths and fatwas (religious opinions of the scholars are used. Some of the articles which were centered around Islamic jurisprudence, particularly Shiite jurisprudence that explain and deal with brain death were given special consideration. FINDINGS: Brain death from religious and jurisprudence perspective is considered the termination of life and removing the vital organs from the body is not viewed as committing manslaughter. A person with brain death is not a normally known injured man who is still alive. The brain death patinets have no life and getting rid of the body does not constitute a case of manslaughter. Amputation of the organs of brain death patients for donation and transplantation amounts to the amputation of a dead body. If the life of a Muslim is subject to transplant of organs from the body of a brain death patient, it will be permissible. CONCLUSION: In principle, if the life of a Muslim entails transplant of organs of brain death patients, it will be permissible

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.

Deaths: leading causes for 2010.

Science.gov (United States)

Heron, Melonie

2013-12-20

This report presents final 2010 data on the 10 leading causes of death in the United States by age, sex, race, and Hispanic origin. Leading causes of infant, neonatal, and postneonatal death are also presented. This report supplements the Division of Vital Statistics' annual report of final mortality statistics. Data in this report are based on information from all death certificates filed in the 50 states and the District of Columbia in 2010. Causes of death classified by the International Classification of Diseases, Tenth Revision (ICD-10) are ranked according to the number of deaths assigned to rankable causes. Cause-of-death statistics are based on the underlying cause of death. In 2010, the 10 leading causes of death were, in rank order: Diseases of heart; Malignant neoplasms; Chronic lower respiratory diseases; Cerebrovascular diseases; Accidents (unintentional injuries); Alzheimer's disease; Diabetes mellitus; Nephritis, nephrotic syndrome and nephrosis; Influenza and pneumonia; and Intentional self-harm (suicide). These 10 causes accounted for 75% of all deaths occurring in the United States. Differences in the rankings are evident by age, sex, race, and Hispanic origin. Leading causes of infant death for 2010 were, in rank order: Congenital malformations, deformations and chromosomal abnormalities; Disorders related to short gestation and low birth weight, not elsewhere classified; Sudden infant death syndrome; Newborn affected by maternal complications of pregnancy; Accidents (unintentional injuries); Newborn affected by complications of placenta, cord and membranes; Bacterial sepsis of newborn; Respiratory distress of newborn; Diseases of the circulatory system; and Necrotizing enterocolitis of newborn. Important variations in the leading causes of infant death are noted for the neonatal and post-neonatal periods.

There are three categories of deceased donors of kidney transplantation in China, donation after brain death (DBD), donation after circulatory death (DCD), and donation after brain death followed by circulatory death (DBCD) donors. The aim of this study was to compare the outcomes of kidney transplantation from these three categories of deceased donors. We retrospectively reviewed 469 recipients who received deceased kidney transplantation in our hospital from February 2007 to June 2015. The recipients were divided into three groups according to the source of their donor kidneys: DBD, DCD, or DBCD. The primary endpoints were delayed graft function (DGF), graft loss, and patient death. The warm ischemia time was much longer in DCD group compared to DBCD group (18.4 minutes vs 12.9 minutes, P < .001). DGF rate was higher in DCD group than in DBD and DBCD groups (22.5% vs 10.2% and 13.8%, respectively, P = .021). Urinary leakage was much higher in DCD group (P = .049). Kaplan-Meier analysis showed that 1-, 2-, and 3-year patient survivals were all comparable among the three groups. DBCD kidney transplantation has lower incidences of DGF and urinary leakage than DCD kidney transplant. However, the overall patient and graft survival were comparable among DBD, DCD, and DBCD kidney transplantation. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Meaning and death-thought accessibility.

Science.gov (United States)

Van Tongeren, Daryl R; Green, Jeffrey D

2018-01-01

Meaning is a central feature in human life, but death can disrupt a sense of meaning. Two experiments tested the hypothesis that meaning in life and meaning in death are distinct types of meaning when mortality is salient and differentially affect death-thought accessibility (DTA). In Experiment 1, imagining a specific scenario in which meaning is preserved beyond death reduced DTA relative to a standard mortality salience prime; moreover, these effects were not due to changes in self-esteem. In Experiment 2, imagining a meaningful life when mortality is salient elicited greater DTA, whereas imagining meaning in death elicited less DTA. Imbuing death with meaning attenuates DTA, whereas meaning in life increases DTA. © 2017 The British Psychological Society.

Blois, Joseph; Smith, Adam; Josephson, Lee

2011-09-01

To examine the correlation between cell death and a common surrogate of death used in screening assays, we compared cell death responses to those obtained with the sulforhodamine B (SRB) cell protein-based "cytotoxicity" assay. With the SRB assay, the Hill equation was used to obtain an IC50 and final cell mass, or cell mass present at infinite agent concentrations, with eight adherent cell lines and four agents (32 agent/cell combinations). Cells were treated with high agent concentrations (well above the SRB IC50) and the death response determined as the time-dependent decrease in cells failing to bind both annexin V and vital fluorochromes by flow cytometry. Death kinetics were categorized as fast (5/32) (similar to the reference nonadherent Jurkat line), slow (17/32), or none (10/32), despite positive responses in the SRB assay in all cases. With slow cell death, a single exposure to a chemotherapeutic agent caused a slow, progressive increase in dead (necrotic) and dying (apoptotic) cells for at least 72 h. Cell death (defined by annexin and/or fluorochrome binding) did not correlate with the standard SRB "cytotoxicity" assay. With the slow cell death response, a single exposure to an agent caused a slow conversion from vital to apoptotic and necrotic cells over at least 72 h (the longest time point examined). Here, increasing the time of exposure to agent concentrations modestly above the SRB IC50 provides a method of maximizing cell kill. If tumors respond similarly, sustained low doses of chemotherapeutic agents, rather than a log-kill, maximum tolerated dose strategy may be an optimal strategy of maximizing tumor cell death.

The population of the Pacific Melanesian country of Vanuatu was 234,000 at the 2009 census. Apart from subsistence activities, economic activity includes tourism and agriculture. Current completeness of vital registration is considered too low to be usable for national statistics; mortality and life expectancy (LE) are derived from indirect demographic estimates from censuses/surveys. Some cause of death (CoD) data are available to provide information on major causes of premature death. Deaths 2001-2007 were coded for cause (ICDv10) for ages 0-59 years from: hospital separations (HS) (n = 636), hospital medical certificates (MC) of death (n = 1,169), and monthly reports from community health facilities (CHF) (n = 1,212). Ill-defined causes were 3 % for hospital deaths and 20 % from CHF. Proportional mortality was calculated by cause (excluding ill-defined) and age group (0-4, 5-14 years), and also by sex for 15-59 years. From total deaths by broad age group and sex from 1999 and 2009 census analyses, community deaths were estimated by deduction of hospital deaths MC. National proportional mortality by cause was estimated by a weighted average of MC and CHF deaths. National estimates indicate main causes of deaths <5 years were: perinatal disorders (45 %) and malaria, diarrhea, and pneumonia (27 %). For 15-59 years, main causes of male deaths were: circulatory disease 27 %, neoplasms 13 %, injury 13 %, liver disease 10 %, infection 10 %, diabetes 7 %, and chronic respiratory disease 7 %; and for females: neoplasms 29 %, circulatory disease 15 %, diabetes 10 %, infection 9 %, and maternal deaths 8 %. Infection included tuberculosis, malaria, and viral hepatitis. Liver disease (including hepatitis and cancer) accounted for 18 % of deaths in adult males and 9 % in females. Non-communicable disease (NCD), including circulatory disease, diabetes, neoplasm, and chronic respiratory disease, accounted for 52 % of premature deaths in adult

Malnutrition related deaths.

Studies have shown that malnutrition increases the risk of morbidity, mortality, the length of hospital stay, and costs in the elderly population. Approximately one third of all patients admitted to geriatric wards in Denmark are malnourished according to the Danish Geriatric database. The aim of this study is to describe and examine the sudden increase in deaths due to malnutrition in the elderly population in Denmark from 1999 and, similarly, the sudden decline in malnutrition related deaths in 2007. A descriptive epidemiologic study was performed. All Danes listed in the national death registry who died from malnutrition in the period from 1994 to 2012 are included. The number of deaths from malnutrition increased significantly during the period from 1999 to 2007, especially in the age group 70 years and over. Additionally, we document a surprising similarity between the development in excess mortality from malnutrition in the five Danish regions during the same period. During the period 1999-2007 malnutrition was the direct cause of 340 extra deaths, and probably ten times more registered under other diseases. This development in excess mortality runs parallel in all five Danish regions over time. Copyright © 2016 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

Referring to our experience with post-mortem computed tomography (CT), many hypothermic death cases presented a lack of increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and urine retention in the bladder. Thus we evaluated the diagnostic performance of post-mortem CT on hypothermic death based on the above-mentioned three findings. Twenty-four hypothermic death subjects and 53 non-hypothermic death subjects were examined. Two radiologists assessed the presence or lack of an increase in lung-field concentration, blood clotting in the heart, thoracic aorta or pulmonary artery, and measured urine volume in the bladder. Pearson's chi-square test and Mann-Whitney U-test were used to assess the relationship between the three findings and hypothermic death. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the diagnosis were also calculated. Lack of an increase in lung-field concentration and blood clotting in the heart, thoracic aorta or pulmonary artery were significantly associated with hypothermic death (p=0.0007, p<0.0001, respectively). The hypothermic death cases had significantly more urine in the bladder than the non-hypothermic death cases (p=0.0011). Regarding the diagnostic performance with all three findings, the sensitivity was 29.2% but the specificity was 100%. These three findings were more common in hypothermic death cases. Although the sensitivity was low, these findings will assist forensic physicians in diagnosing hypothermic death since the specificity was high. Copyright © 2012 Elsevier Ireland Ltd.

Violent Deaths and Traumatic Bereavement: The Importance of Appropriate Death Notification

Directory of Open Access Journals (Sweden)

Diego de Leo

2015-10-01

Full Text Available The communication of a death due to unexpected and traumatic causes is considered a very sensitive issue that can deeply affect both operators responsible for reporting the incident and the mourning process of family members, relatives, and other survivors. By focusing particularly on cases of traumatic death, this article tries to explain how inadequate communication of death may adversely affect the course of mourning. The article also illustrates the basic principles of correct notification of death. In this way, we hope to contribute to the ongoing dialogue on this topic and the promotion of new studies aimed at setting best practices for those professionally involved in the challenging task of communicating that a life has ended. This would be important in order to safeguard the emotional integrity of notifiers whilst effectively helping the survivors to cope with the early stages of their difficult mourning process.

This study was conducted to describe trends in US lead poisoning-relate deaths between 1979 and 1998. The predictive value of relevant ICD-9 codes was also evaluated. Multiple cause-of-death files were searched for record containing relevant ICD-9 codes, and underlying causes and demographic characteristics were assessed. For 1979-1988, death certificates were reviewed; lead source information was abstracted and accuracy of coding was determined. An estimated 200 lead poisoning-related deaths occurred from 1979 to 1998. Most were among males (74%), Blacks (67%), adults of age ≥45 years (76%), and Southerners (70%). The death rate was significantly lower in more recent years. An alcohol-related code was a contributing cause for 28% of adults. Only three of nine ICD-9 codes for lead poisoning were highl predictive of lead poisoning-related deaths. In conclusion, lead poisoning-related death rates have dropped dramatically since earlier decades and are continuing to decline. However, the findings imply that moonshine ingestion remains a source of high-dose lead exposure in adults

Reducing neonatal deaths in South Africa: Progress and challenges

Directory of Open Access Journals (Sweden)

N Rhoda

2018-03-01

Full Text Available Although current levels of the neonatal mortality rate (NMR are within reach of the Sustainable Development Goal (SDG target of 12 per 1 000 live births, the absolute number of deaths is unacceptably high for a lower-middle-income country such as South Africa (SA. Neonatal mortality over the last decade has declined very slowly, and is not commensurate with the level of government investment in healthcare. The recent neonatal mortality rate of 21 per 1 000 live births reported by the SA Demographic Health Survey is of major concern. This paper reviews recent efforts to reduce the neonatal mortality rate, including support for the implementation of neonatal policies and plans, and strengthening programmes to deliver low-cost, high-impact interventions. We review recent estimates of the NMR and causes of neonatal deaths, and discuss how the mortality from preventable causes of death could be reduced. If SA is to meet the SDG target, special attention should be given to the availability of high-impact interventions, providing an adequate number of appropriately trained healthcare providers and a more active role played by ward-based community health workers and district clinical specialist teams.

Prospective risk of fetal death in uncomplicated monochorionic twins.

LENUS (Irish Health Repository)

Farah, Nadine

2012-03-01

A retrospective cohort study was carried out in a university teaching hospital to determine the prospective risk of unexpected fetal death in uncomplicated monochorionic diamniotic (MCDA) twin pregnancies after viability. All MCDA twins delivered at or after 24 weeks\\' gestation from July 1999 to July 2007 were included. Pregnancies with twin-twin transfusion syndrome, growth restriction, structural abnormalities, or twin reversed arterial perfusion sequence were excluded. Of the 144 MCDA twin pregnancies included in our analysis, the risk of intrauterine death was 4.9%. The prospective risk of unexpected intrauterine death was 1 in 43 after 32 weeks\\' gestation and 1 in 37 after 34 weeks\\' gestation. Our results demonstrate that despite close surveillance, the unexpected intrauterine death rate in uncomplicated MCDA twin pregnancies is high. This rate seems to increase after 34 weeks\\' gestation, suggesting that a policy of elective preterm delivery warrants evaluation.

The Lombardy region in northern Italy ranks among the most air polluted areas of Europe. Previous studies showed air pollution short-term effects on all-cause mortality. We examine here the effects of particulate matter with aerodynamic diameter ≤10µm (PM10) and nitrogen dioxide (NO2) exposure on deaths and hospitalizations from specific causes, including cardiac, cerebrovascular and respiratory diseases. We considered air pollution, mortality and hospitalization data for a non-opportunistic sample of 18 highly polluted and most densely populated areas of the region in the years 2003-2006. We obtained area-specific effect estimates for PM10 and NO2 from a Poisson regression model on the daily number of total deaths or cause-specific hospitalizations and then combined them in a Bayesian random-effects meta-analysis. For cause-specific mortality, we applied a case-crossover analysis. Age- and season-specific analyses were also performed. Effect estimates were expressed as percent variation in mortality or hospitalizations associated with a 10µg/m(3) increase in PM10 or NO2 concentration. Natural mortality was positively associated with both pollutants (0.30%, 90% Credibility Interval [CrI]: -0.31; 0.78 for PM10; 0.70%, 90%CrI: 0.10; 1.27 for NO2). Cardiovascular deaths showed a higher percent variation in association with NO2 (1.12%, 90% Confidence Interval [CI]: 0.14; 2.11), while the percent variation for respiratory mortality was highest in association with PM10 (1.64%, 90%CI: 0.35; 2.93). The effect of both pollutants was more evident in the summer season. Air pollution was also associated to hospitalizations, the highest variations being 0.77% (90%CrI: 0.22; 1.43) for PM10 and respiratory diseases, and 1.70% (90%CrI: 0.39; 2.84) for NO2 and cerebrovascular diseases. The effect of PM10 on respiratory hospital admissions appeared to increase with age. For both pollutants, effects on cerebrovascular hospitalizations were more evident in subjects aged less than

Parthanatos, a messenger of death

Poly-ADP-ribose polymerase-1 (PARP-1)'s multiple roles in the cell span from maintaining life to inducing death. The processes PARP-1 is involved in include, but are not limited to DNA repair, DNA transcription, mitosis, and cell death. Of PARP-1's different cellular functions, its active role in cell death is of particular interest to designing therapies for diseases. Genetic deletion of PARP-1 revealed that PARP-1 over activation underlies cell death in experimental models of stroke, diabetes, inflammation and neurodegeneration. Since interfering with PARP-1 mediated cell death will be clinically beneficial, great effort has been invested into designing PARP-1 inhibitors and understanding mechanisms downstream of PARP-1 over activation. PARP-1 overactivation may kill by depleting cellular energy through nicotinamide adenine dinucleotide (NAD+) consumption, and by releasing the cell death effector apoptosis-inducing factor (AIF). Unexpectedly, recent evidence shows that poly-ADP ribose (PAR) polymer itself, and not the consumption of NAD+ is the source of cytotoxicity. Thus, PAR polymer acts as a cell death effector downstream of PARP-1-mediated cell death signaling. We coined the term parthanatos after Thanatos, the personification of death in Greek mythology, to refer to PAR-mediated cell death. In this review, we will summarize the proposed mechanisms by which PARP-1 overactivation kills. We will present evidence for parthanatos, and the questions raised by these recent findings. It is evident that further understanding of parthanatos opens up new avenues for therapy in ameliorating diseases related to PARP-1 over activation. PMID:19273119

To describe the changes in death rates and causes of deaths in Norwegian police cells during the last 2 decades. To review reports on death rates in police cells that have been published in medical journals and elsewhere, and discuss the difficulties of comparing death rates between countries. Data on deaths in Norwegian police cells were collected retrospectively in 2002 and 2012 for two time periods: 1993-2001 (period 1) and 2003-2012 (period 2). Several databases were searched to find reports on deaths in police cells from as many countries as possible. The death rates in Norwegian police cells reduced significantly from 0.83 deaths per year per million inhabitants (DYM) in period 1 to 0.22 DYM in period 2 (p police cells reduced by about 75% over a period of approximately 10 years. This is probably mainly due to individuals with severe alcohol intoxication no longer being placed in police cells. However, there remain large methodology difficulties in comparing deaths rates between countries. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

The Spectrum of Epidemiology Underlying Sudden Cardiac Death

Science.gov (United States)

Hayashi, Meiso; Shimizu, Wataru; Albert, Christine M.

2015-01-01

Sudden cardiac death (SCD) from cardiac arrest is a major international public health problem accounting for an estimated 15–20% of all deaths. Although resuscitation rates are generally improving throughout the world, the majority of individuals who suffer a sudden cardiac arrest will not survive. SCD most often develops in older adults with acquired structural heart disease, but it also rarely occurs in the young, where it is more commonly due to inherited disorders. Coronary heart disease (CHD) is known to be the most common pathology underlying SCD, followed by cardiomyopathies, inherited arrhythmia syndromes, and valvular heart disease. Over the past three decades, declines in SCD rates have not been as steep as for other causes of CHD deaths, and there is a growing fraction of SCDs not due to CHD and/or ventricular arrhythmias, particularly among certain subsets of the population. The growing heterogeneity of the pathologies and mechanisms underlying SCD present major challenges for SCD prevention, which are magnified further by a frequent lack of recognition of the underlying cardiac condition prior to death. Multifaceted preventative approaches, which address risk factors in seemingly low risk and known high-risk populations will be required to decrease the burden of SCD. In this Compendium, we review the wide-ranging spectrum of epidemiology underlying SCD within both the general population and in high-risk subsets with established cardiac disease placing an emphasis on recent global trends, remaining uncertainties, and potential targeted preventive strategies.

The role of forensic death investigators interacting with the survivors of death by homicide and suicide.

Science.gov (United States)

Baumann, Robin; Stark, Sharon

2015-01-01

When sudden unexpected death occurs, an investigation ensues in an attempt to discover the cause and manner of death. Autopsies are performed when reasons for death are not obvious. They are used to provide information, confirm the cause of death, and/or reveal conditions not recognized before death (Hendricks, 2011). One important reason for performing an autopsy is to help families to understand what happened to their loved one so that they can begin the process of grieving. The way that the initial notification and investigation is handled can have a bearing on how a family's grief progresses. Forensic nurses are in a unique position to bring a holistic approach to death investigation with a focus of care that includes not only the decedent but the surviving loved ones as well (Koehler, 2008). Forensic nurse death investigators can assist families through initial stages of grief in the investigation of death.

The convergence of radiation and immunogenic cell death signaling pathways

International Nuclear Information System (INIS)

Golden, Encouse B.; Pellicciotta, Ilenia; Demaria, Sandra; Barcellos-Hoff, Mary H.; Formenti, Silvia C.

2012-01-01

Ionizing radiation (IR) triggers programmed cell death in tumor cells through a variety of highly regulated processes. Radiation-induced tumor cell death has been studied extensively in vitro and is widely attributed to multiple distinct mechanisms, including apoptosis, necrosis, mitotic catastrophe (MC), autophagy, and senescence, which may occur concurrently. When considering tumor cell death in the context of an organism, an emerging body of evidence suggests there is a reciprocal relationship in which radiation stimulates the immune system, which in turn contributes to tumor cell kill. As a result, traditional measurements of radiation-induced tumor cell death, in vitro, fail to represent the extent of clinically observed responses, including reductions in loco-regional failure rates and improvements in metastases free and overall survival. Hence, understanding the immunological responses to the type of radiation-induced cell death is critical. In this review, the mechanisms of radiation-induced tumor cell death are described, with particular focus on immunogenic cell death (ICD). Strategies combining radiotherapy with specific chemotherapies or immunotherapies capable of inducing a repertoire of cancer specific immunogens might potentiate tumor control not only by enhancing cell kill but also through the induction of a successful anti-tumor vaccination that improves patient survival.

Full Text Available Children diagnosed with autistic spectrum disorders (ASD may have serious behavioral problems such as aggression, self-injury, and violence. However, the literature on ASD either overrules any correlation between aggression and ASD or maintains the fact that the efforts to link them have so far been inconclusive. Although severe forms of violence are extremely rare in children with autism, there are a few cases reported in the literature with significant harm to siblings. We hereby report an 8-year-old boy with ASD who caused the death of his sibling by throwing her out of the window. Shared similarities of all defenestration cases indicate a pattern of high-risk behavior threatening the survival of minors. We recommend precautions against this high-risk behavior in children with ASD.

Full Text Available Sudden death in the young is rare. About 25% of cases occur during sports. Most young people with sudden cardiac death (SCD have underlying heart disease, with hypertrophic cardiomyopathy and coronary artery anomalies being commonest in most series. Arrhythmogenic right ventricular dysplasia and long QT syndrome are the most common primary arrhythmic causes of SCD. It is estimated that early cardiopulmonary resuscitation and widespread availability of automatic external defibrillators could prevent about a quarter of pediatric sudden deaths.

Full Text Available Objective. High glucose- (HG- induced neuronal cell death is responsible for the development of diabetic neuropathy. However, the effect of HG on metabolism in neuronal cells is still unclear. Materials and Methods. The neural-crest derived PC12 cells were cultured for 72 h in the HG (75 mM or control (25 mM groups. We used NMR-based metabolomics to examine both intracellular and extracellular metabolic changes in HG-treated PC12 cells. Results. We found that the reduction in intracellular lactate may be due to excreting more lactate into the extracellular medium under HG condition. HG also induced the changes of other energy-related metabolites, such as an increased succinate and creatine phosphate. Our results also reveal that the synthesis of glutamate from the branched-chain amino acids (isoleucine and valine may be enhanced under HG. Increased levels of intracellular alanine, phenylalanine, myoinositol, and choline were observed in HG-treated PC12 cells. In addition, HG-induced decreases in intracellular dimethylamine, dimethylglycine, and 3-methylhistidine may indicate a downregulation of methyl group metabolism. Conclusions. Our metabolomic results suggest that HG-induced neuronal cell death may be attributed to a series of metabolic changes, involving energy metabolism, amino acids metabolism, osmoregulation and membrane metabolism, and methyl group metabolism.

Concept of 'bad death'

Full Text Available Following previous research on the linguistic concept of а 'bad death' which lexical expression is the word family of the verb ginuti, I focus my attention in this paper on the relationship between language conceptualization of а 'bad death' and the representation of а 'bad death' in traditional and contemporary culture. Diachronically based language corpus makes possible to trace the changes of referential frame and use of verb ginuti and its derivatives. In the traditional culture а 'bad death' is marked in action code by irregular way of burial and beliefs in demons stemming from the 'impure dead'. In the paper I explore the degree of synonymy of the symbols of all three codes: verbal code, action code and code of beliefs. In the contemporary culture the lack of individual control and choice is considered to be the key element of the concept of a 'bad death'. This change of conceptual content manifests itself in the use of its lexical expressions.

Programmed cell death (PCD) is a genetically-based cell death mechanism with vital roles in eukaryotes. Although there is limited consensus on similar death mode programs in prokaryotes, emerging evidence suggest that PCD events are operative. Here we present cell death events in a cyanobacterium living endophytically in the fern Azolla microphylla, suggestive of PCD. This symbiosis is characterized by some unique traits such as a synchronized development, a vertical transfer of the cyanobacterium between plant generations, and a highly eroding cyanobacterial genome. A combination of methods was used to identify cell death modes in the cyanobacterium. Light- and electron microscopy analyses showed that the proportion of cells undergoing cell death peaked at 53.6% (average 20%) of the total cell population, depending on the cell type and host developmental stage. Biochemical markers used for early and late programmed cell death events related to apoptosis (Annexin V-EGFP and TUNEL staining assays), together with visualization of cytoskeleton alterations (FITC-phalloidin staining), showed that all cyanobacterial cell categories were affected by cell death. Transmission electron microscopy revealed four modes of cell death: apoptotic-like, autophagic-like, necrotic-like and autolytic-like. Abiotic stresses further enhanced cell death in a dose and time dependent manner. The data also suggest that dynamic changes in the peptidoglycan cell wall layer and in the cytoskeleton distribution patterns may act as markers for the various cell death modes. The presence of a metacaspase homolog (domain p20) further suggests that the death modes are genetically programmed. It is therefore concluded that multiple, likely genetically programmed, cell death modes exist in cyanobacteria, a finding that may be connected with the evolution of cell death in the plant kingdom.

Life and death.

Lloyd, J W

In contrast with the other lectures given in the course on humanics and bioethics at the UOEH, which address the questions of life and death from the standpoint of the physician or the philosopher, this lecture considers these issues as seen by the cancer patient who has had a close encounter with death. The attitudes of Americans concerning abortion, the use of life-support systems, "mercy killings", suicide and the use of cancer chemotherapy are discussed with particular emphasis on restraints imposed by the courts, the churches and the family systems. An attempt is made to contrast the American and Japanese attitudes on these questions but this is difficult because of different cultural and religious backgrounds. The author describes his own experiences as a cancer patient who has approached death very closely and the changes in his own attitude toward life which results from the encounter with death. He also talks about the joy of being alive and describes his own experience with receiving cancer chemotherapy, the resulting discomfort and inconveniences and his feelings about a "tolerable" existence. Finally, the author considers the question of the "quality of life" for the cancer patient who has a violent reaction to certain forms of chemotherapy. This is a dilemma for the patient and the doctor who must consider the choice between death and a miserable existence.

Using stochastic cell division and death to probe minimal units of cellular replication

The invariant cell initiation mass measured in bacterial growth experiments has been interpreted as a minimal unit of cellular replication. Here we argue that the existence of such minimal units induces a coupling between the rates of stochastic cell division and death. To probe this coupling we tracked live and dead cells in Escherichia coli populations treated with a ribosome-targeting antibiotic. We find that the growth exponent from macroscopic cell growth or decay measurements can be represented as the difference of microscopic first-order cell division and death rates. The boundary between cell growth and decay, at which the number of live cells remains constant over time, occurs at the minimal inhibitory concentration (MIC) of the antibiotic. This state appears macroscopically static but is microscopically dynamic: division and death rates exactly cancel at MIC but each is remarkably high, reaching 60% of the antibiotic-free division rate. A stochastic model of cells as collections of minimal replicating units we term ‘widgets’ reproduces both steady-state and transient features of our experiments. Sub-cellular fluctuations of widget numbers stochastically drive each new daughter cell to one of two alternate fates, division or death. First-order division or death rates emerge as eigenvalues of a stationary Markov process, and can be expressed in terms of the widget’s molecular properties. High division and death rates at MIC arise due to low mean and high relative fluctuations of widget number. Isolating cells at the threshold of irreversible death might allow molecular characterization of this minimal replication unit.

Brain death and related issues

Concerns about the erroneous diagnosis of death and premature burial have been expressed from times immemorial. Patients with brain stem death have absolutely no chance of recovery. Brain death is considered at par with death in most of the countries. General public in most parts of the world shows reluctance to accept this concept due to different social, cultural and religious backgrounds and state of literacy and awareness. The criteria for the diagnosis of brain death have been established which include certain pre-conditions, exclusions and tests of the brain stem function. These criteria are universally accepted. The criteria in children are somewhat different from the adults. The subject is intimately related with organ transplantation. If the patients is registered as organ donor or the family consents, organs can be harvested from brain dead patients for transplantation. Pakistan is amongst the few countries where no legislation exists to accept brain death as being at par with death of an individual, and to facilitate and regulate, cadaveric organ donation and transplantation.

For the pending National Claims Database in Japan, researchers will not have access to death information in the enrollment files. We developed and evaluated a claims-based definition of death. We used healthcare claims and enrollment data between January 2005 and August 2009 for 195,193 beneficiaries aged 20 to 74 in 3 private health insurance unions. We developed claims-based definitions of death using discharge or disease status and Charlson comorbidity index (CCI). We calculated sensitivity, specificity and positive predictive values (PPVs) using the enrollment data as a gold standard in the overall population and subgroups divided by demographic and other factors. We also assessed bias and precision in two example studies where an outcome was death. The definition based on the combination of discharge/disease status and CCI provided moderate sensitivity (around 60%) and high specificity (99.99%) and high PPVs (94.8%). In most subgroups, sensitivity of the preferred definition was also around 60% but varied from 28 to 91%. In an example study comparing death rates between two anticancer drug classes, the claims-based definition provided valid and precise hazard ratios (HRs). In another example study comparing two classes of anti-depressants, the HR with the claims-based definition was biased and had lower precision than that with the gold standard definition. The claims-based definitions of death developed in this study had high specificity and PPVs while sensitivity was around 60%. The definitions will be useful in future studies when used with attention to the possible fluctuation of sensitivity in some subpopulations.

The direct and indirect effects of corruption on motor vehicle crash deaths.

Hua, Law Teik; Noland, Robert B; Evans, Andrew W

2010-11-01

Recent empirical research has found that there is an inverted U-shaped or Kuznets relationship between income and motor vehicle crash (MVC) deaths, such that MVC deaths increase as national income increases and decrease after reaching a critical level. Corruption has been identified as one of the underlying factors that could affect this relationship, primarily by undermining institutional development and effective enforcement schemes. The total effect of corruption can be decomposed into two components, a direct and an indirect effect. The direct effect measures the immediate impact of corruption on MVC deaths by undermining effective enforcement and regulations, while the indirect effect captures the impact of corruption on hindering increases in per capita income and the consequent impact of reduced income on MVC deaths. By influencing economic growth, corruption can lead to an increase or decrease in MVC deaths depending on the income level. Using data from 60 countries between 1982 and 2003, these effects are estimated using linear panel and fixed effects negative binomial models. The estimation results suggest that corruption has different direct effects for less developed and highly developed countries. It has a negative (decreasing) effect on MVC deaths for less developed countries and a positive (increasing) effect on MVC deaths for highly developed countries. For highly developed countries, the total effect is positive at lower per capita income levels, but decreases with per capita income and becomes negative at per capita income levels of about US$ 38,248. For less developed countries, the total effect is negative within the sample range and decreases with increased per capita income. In summary, the results of this study suggest that reduction of corruption is likely a necessary condition to effectively tackle road safety problems. 2010 Elsevier Ltd. All rights reserved.

Using multiple cause-of-death data to investigate associations and causality between conditions listed on the death certificate.

Death rarely results from only one cause, and it can be caused by a variety of factors. Multiple cause-of-death data files can list as many as 20 contributing causes of death in addition to the reported underlying cause of death. Analysis of multiple cause-of-death data can provide information on associations between causes of death, revealing common combinations of events or conditions which lead to death. Additionally, physicians report the causal train of events through which they believe that different conditions or events may have led to each other and ultimately caused death. In this paper, the authors discuss methods used in studying associations between reported causes of death and in investigating commonly reported causal pathways between events or conditions listed on the death certificate.

Hospital deaths and adverse events in Brazil

2011-09-01

Full Text Available Abstract Background Adverse events are considered a major international problem related to the performance of health systems. Evaluating the occurrence of adverse events involves, as any other outcome measure, determining the extent to which the observed differences can be attributed to the patient's risk factors or to variations in the treatment process, and this in turn highlights the importance of measuring differences in the severity of the cases. The current study aims to evaluate the association between deaths and adverse events, adjusted according to patient risk factors. Methods The study is based on a random sample of 1103 patient charts from hospitalizations in the year 2003 in 3 teaching hospitals in the state of Rio de Janeiro, Brazil. The methodology involved a retrospective review of patient charts in two stages - screening phase and evaluation phase. Logistic regression was used to evaluate the relationship between hospital deaths and adverse events. Results The overall mortality rate was 8.5%, while the rate related to the occurrence of an adverse event was 2.9% (32/1103 and that related to preventable adverse events was 2.3% (25/1103. Among the 94 deaths analyzed, 34% were related to cases involving adverse events, and 26.6% of deaths occurred in cases whose adverse events were considered preventable. The models tested showed good discriminatory capacity. The unadjusted odds ratio (OR 11.43 and the odds ratio adjusted for patient risk factors (OR 8.23 between death and preventable adverse event were high. Conclusions Despite discussions in the literature regarding the limitations of evaluating preventable adverse events based on peer review, the results presented here emphasize that adverse events are not only prevalent, but are associated with serious harm and even death. These results also highlight the importance of risk adjustment and multivariate models in the study of adverse events.

Casino-related deaths in Atlantic City, New Jersey 1982-1986.

The first legalized casino-hotel opened in Atlantic City, New Jersey in 1978. Annually, more than 30 million people visit the "Gambling Capitol of the East Coast." As a result of this growing influx of people, the Atlantic County Medical Examiner's Office began compiling statistics in 1982 of casino-related deaths. Data on 398 casino-related deaths occurring in 1982-1986 were collected and analyzed: 83% of the total number of fatalities were sudden cardiac deaths. Most of the victims were elderly white retired men who had previously diagnosed medical conditions. Many of the victims' underlying medical problems are of a type known to be associated with compulsive gambling. The majority of deaths occurred during the afternoon hours on weekends in October, January, and May. Of the victims, 86% were from New Jersey, New York, and Pennsylvania. For Atlantic City, a gambling community known to have a relatively high rate of crime and drug-trafficking, only 1% of all deaths were homicides. We speculate that the stress of gambling activities may induce sudden cardiac death. We therefore recommend that communities planning to legalize casino gambling mandate that gambling establishments provide emergency health care services for their patrons.

Benefits from reducing risk of death

Of the categories of benefits to individuals, reductions in the risk of premature mortality are of central. concern to the public and environmental policy makers. These benefits can include those from reductions in own- risk, for example, an individual's valuation of reducing his or her own mortality risks; reductions in risk to an individual's family, friends, or co-workers (i.e., of people known to the individual); and reductions in risks to unknown individuals. The last type would be an example of altruistic value. The overall goal is to measure the welfare change from a change in the current and/or future probability of dying. The willingness to pay (WTP) reflects the amount of income taken from a person that would leave him or her indifferent to a decrease in risk, whenever it occurs. When this value is divided by the risk change, the resulting value is called the 'value of a statistical life'. Another relevant measure appearing in the literature is the value of life-years saved. A final issue concerns the type of premature mortality risks one is valuing when environmental pollution is at issue. While most effort has gone into estimating the welfare effects of a change in current probability of death of healthy workers on the job, this is more relevant for characterizing the benefits of reducing accidental death risks than death from environmental causes. Exposure to pollutants raises risks of developing cancer, chronic heart, respiratory, and other diseases that raise mortality risks in the future. Such exposure also may raise current death risks for the very old and the sick. But, surely the pollution effect that is analogous to occupational health risks-pollution exposures high enough to raise current risks of death for the healthy, prime-age person-is insignificant in the United States.

The process and promotion of radiation-induced cell death

International Nuclear Information System (INIS)

Sasaki, Hiroshi

1998-01-01

Radiation-induced cell death is divided into reproductive and interphase death, whose process can be revealed by time-lapse observations. Pedigree analyses of progenies derived from a surviving progenitor cell have shown that moribund cells appear in clusters among cells which are apparently undamaged (lethal sectoring). Sister cell fusion, which likely results from chromosome bridge, is the most frequently observed cell abnormality leading to reproductive death. While interphase death does not occur unless the dose exceeds 10 Gy for low LET radiation such as X-rays, high-LET radiation is very effective at inducing interphase death (RBE: ≅3 at 230 keV/μm). Expression or fixation of potentially lethal damage (PLD) is closely associated with cell cycle events and enhanced by inducing premature chromosome condensation (PCC) at a nonpermissive temperature in tsBN2 cells with a ts-defect in RCC1 protein (a regulator of chromatin condensation) which monitors the completion of DNA replication. Furthermore, higher-order structural changes in nuclear matrix such as induced by leptomycin B, an inhibitor of CRM1 (chromosome region maintenance) protein, also play an important role in the fixation of PLD.

High fat programming of beta cell compensation, exhaustion, death and dysfunction.

Science.gov (United States)

Cerf, Marlon E

2015-03-01

Programming refers to events during critical developmental windows that shape progeny health outcomes. Fetal programming refers to the effects of intrauterine (in utero) events. Lactational programming refers to the effects of events during suckling (weaning). Developmental programming refers to the effects of events during both fetal and lactational life. Postnatal programming refers to the effects of events either from birth (lactational life) to adolescence or from weaning (end of lactation) to adolescence. Islets are most plastic during the early life course; hence programming during fetal and lactational life is most potent. High fat (HF) programming is the maintenance on a HF diet (HFD) during critical developmental life stages that alters progeny metabolism and physiology. HF programming induces variable diabetogenic phenotypes dependent on the timing and duration of the dietary insult. Maternal obesity reinforces HF programming effects in progeny. HF programming, through acute hyperglycemia, initiates beta cell compensation. However, HF programming eventually leads to chronic hyperglycemia that triggers beta cell exhaustion, death and dysfunction. In HF programming, beta cell dysfunction often co-presents with insulin resistance. Balanced, healthy nutrition during developmental windows is critical for preserving beta cell structure and function. Thus early positive nutritional interventions that coincide with the development of beta cells may reduce the overwhelming burden of diabetes and metabolic disease. © 2014 John Wiley & Sons A/S.

Effects of intracellular iron overload on cell death and identification of potent cell death inhibitors.

Fang, Shenglin; Yu, Xiaonan; Ding, Haoxuan; Han, Jianan; Feng, Jie

2018-06-11

Iron overload causes many diseases, while the underlying etiologies of these diseases are unclear. Cell death processes including apoptosis, necroptosis, cyclophilin D-(CypD)-dependent necrosis and a recently described additional form of regulated cell death called ferroptosis, are dependent on iron or iron-dependent reactive oxygen species (ROS). However, whether the accumulation of intracellular iron itself induces ferroptosis or other forms of cell death is largely elusive. In present study, we study the role of intracellular iron overload itself-induced cell death mechanisms by using ferric ammonium citrate (FAC) and a membrane-permeable Ferric 8-hydroxyquinoline complex (Fe-8HQ) respectively. We show that FAC-induced intracellular iron overload causes ferroptosis. We also identify 3-phosphoinositide-dependent kinase 1 (PDK1) inhibitor GSK2334470 as a potent ferroptosis inhibitor. Whereas, Fe-8HQ-induced intracellular iron overload causes unregulated necrosis, but partially activates PARP-1 dependent parthanatos. Interestingly, we identify many phenolic compounds as potent inhibitors of Fe-8HQ-induced cell death. In conclusion, intracellular iron overload-induced cell death form might be dependent on the intracellular iron accumulation rate, newly identified cell death inhibitors in our study that target ferroptosis and unregulated oxidative cell death represent potential therapeutic strategies against iron overload related diseases.

The aim of this study was to gain information useful to improve traffic safety, concerning the following aspects for DUI (Driving Under the Influence): frequency, reasons, perceived risk, drivers' knowledge of the related penalties, perceived likelihood of being punished, drivers' perception of the harshness of punitive measures and drivers' perception of the probability of behavioral change after punishment for DUI. A sample of 1100 Spanish drivers, 678 men and 422 women aged from 14 to 65 years old, took part in a telephone survey using a questionnaire to gather sociodemographic and psychosocial information about drivers, as well as information on enforcement, clustered in five related categories: "Knowledge and perception of traffic norms"; "Opinions on sanctions"; "Opinions on policing"; "Opinions on laws" (in general and on traffic); and "Assessment of the effectiveness of various punitive measures". Results showed around 60% of respondents believe that driving under the influence of alcohol is maximum risk behavior. Nevertheless, 90.2% of the sample said they never or almost never drove under the influence of alcohol. In this case, the main reasons were to avoid accidents (28.3%) as opposed to avoiding sanctions (10.4%). On the contrary, the remaining 9.7% acknowledged they had driven after consuming alcohol. It is noted that the main reasons for doing so were "not having another way to return home" (24.5%) and alcohol consumption being associated with meals (17.3%). Another important finding is that the risk perception of traffic accident as a result of DUI is influenced by variables such as sex and age. With regard to the type of sanctions, 90% think that DUI is punishable by a fine, 96.4% that it may result in temporary or permanent suspension of driving license, and 70% that it can be punished with imprisonment. Knowing how alcohol consumption impairs safe driving and skills, being aware of the associated risks, knowing the traffic regulations concerning

Artificial insemination technique and semen preparation impact boar utilization efficiency, genetic dissemination, and biosecurity. Intrauterine (IUI) and deep intrauterine (DUI) AI techniques require lower number of spermatozoa per dose compared to conventional (CON) AI. Frozen semen (FRO) has been associated with lower reproductive performance compared to fresh semen (FRE) preparation. The combined effects of 3 AI techniques (CON, IUI, and DUI) and 2 semen preparations (FRE and FRO) on the financial indicators of a pig crossbreeding system were studied. A 3-tier system was simulated in ZPLAN and the genetic improvement in a representative scenario was characterized. The cross of nucleus lines B and A generated 200,000 BA sows at the multiplier level. The BA sows were inseminated (CON, IUI, or DUI) with FRE or FRO from line C boars at the commercial level. Semen preparation and AI technique were represented by distinct sow:boar ratios in the C × BA cross. A range of farrowing rates (60 to 90%) and litter sizes (8 to 14 liveborn pigs) were tested. Genetic improvement per year for number born alive, adjusted 21-d litter weight, days to 113.5 kg, backfat, and ADG were 0.01 pigs per litter, 0.06 kg, -0.09 d, -0.29 mm, and 0.88 g, respectively. On average, the net profit for FRE (FRO) increased (P-value profit between techniques were driven by differences in costs. Differences in fixed costs between IUI and DUI relative to CON were -2.4 (-5.2%) and -3.4% (-7.4%), respectively. The differences in total costs between FRE and FRO were lower than -5%. The difference in variable costs between FRE and FRO ranged from -5.3 (CON) to -24.7% (DUI). Overall, insemination technique and semen preparation had a nonlinear effect on profit. The average relative difference in profit between FRE and FRO was less than 3% for the scenarios studied.

The purpose of our study was to characterize the causes of death among cancer patients as a function of objectives: (i) calendar year, (ii) patient age, and (iii) time after diagnosis. US death certificate data in Surveillance, Epidemiology, and End Results Stat 8.2.1 were used to categorize cancer patient death as being due to index-cancer, nonindex-cancer, and noncancer cause from 1973 to 2012. In addition, data were characterized with standardized mortality ratios (SMRs), which provide the relative risk of death compared with all persons. The greatest relative decrease in index-cancer death (generally from > 60% to deaths were stable (typically >40%) among patients with cancers of the liver, pancreas, esophagus, and lung, and brain. Noncancer causes of death were highest in patients with cancers of the colorectum, bladder, kidney, endometrium, breast, prostate, testis; >40% of deaths from heart disease. The highest SMRs were from nonbacterial infections, particularly among 1,000 for lymphomas, P death from index- and nonindex-cancers varies widely among primary sites. Risk of noncancer deaths now surpasses that of cancer deaths, particularly for young patients in the year after diagnosis. © The Author 2016.

Full Text Available This article aims at understanding ordinary Tehran residents’ attitudes towards Death and Dying and recognizes the relationship between Death and Religion in their thoughts. Using Grounded Theory as method and semi structured interview as a technique, we reached to nine different Cultural scripts of death and dying among interviewees, including: fatalistic death, resurrection-oriented death, martyrdom-oriented death, mystical death, secular death, aesthetic/nihilistic death, agnostic death, and ambiguity-oriented death. Furthermore, we recognized religious and non-religious cultural scripts besides the rationalization and individualization of religion among them. According to our findings, there is no accordance between some interviewees’ thoughts and beliefs with their behavior and lifestyle so that one cannot guess people’s attitudes towards death and dying from their behavior or their appearance. In other words, we face no structural Homology between their ideas and their lifestyle. Moreover, most interviewees had mixed ideas and beliefs about death and dying, and it can indicate the social and cultural complexity of Tehran society.

Human Peritoneal Mesothelial Cell Death Induced by High-Glucose Hypertonic Solution Involves Ca2+ and Na+ Ions and Oxidative Stress with the Participation of PKC/NOX2 and PI3K/Akt Pathways

Directory of Open Access Journals (Sweden)

Felipe Simon

Full Text Available Chronic peritoneal dialysis (PD therapy is equally efficient as hemodialysis while providing greater patient comfort and mobility. Therefore, PD is the treatment of choice for several types of renal patients. During PD, a high-glucose hyperosmotic (HGH solution is administered into the peritoneal cavity to generate an osmotic gradient that promotes water and solutes transport from peritoneal blood to the dialysis solution. Unfortunately, PD has been associated with a loss of peritoneal viability and function through the generation of a severe inflammatory state that induces human peritoneal mesothelial cell (HPMC death. Despite this deleterious effect, the precise molecular mechanism of HPMC death as induced by HGH solutions is far from being understood. Therefore, the aim of this study was to explore the pathways involved in HGH solution-induced HPMC death. HGH-induced HPMC death included influxes of intracellular Ca2+ and Na+. Furthermore, HGH-induced HPMC death was inhibited by antioxidant and reducing agents. In line with this, HPMC death was induced solely by increased oxidative stress. In addition to this, the cPKC/NOX2 and PI3K/Akt intracellular signaling pathways also participated in HGH-induced HPMC death. The participation of PI3K/Akt intracellular is in agreement with previously shown in rat PMC apoptosis. These findings contribute toward fully elucidating the underlying molecular mechanism mediating peritoneal mesothelial cell death induced by high-glucose solutions during peritoneal dialysis.

2005-01-01

Full Text Available Anorexia Nervosa (AN usually follows a prolonged course accompanied by significant morbidity and high mortality. AN patients have been found to have elevated and attempted suicide rates, with suicide being the second most common cause of death in AN after the complications of the disorder itself. The suicide risk in AN is similar to that in major depression or conduct disorder and linked mainly to longer duration of illness, lower weight, bingeing and purging, impulsivity-related manifestations, comorbid substance abuse, and affective disorder. This paper reviews suicidal tendency and disturbed body image, death and eating disorders, and attachment and death with clinical implications related to AN.

Religious characteristics and the death penalty.

Science.gov (United States)

Miller, Monica K; Hayward, R David

2008-04-01

Using one mock trial scenario, this study investigated whether religious and demographic factors were related to death penalty attitudes and sentencing verdicts. Those who favored the death penalty differed from those who had doubts about the penalty in gender, affiliation, fundamentalism, evangelism, literal Biblical interpretism, beliefs about God's attitudes toward murders, and perceptions of how their religious groups felt about the death penalty. These relationships generally held after mock jurors were death qualified. Gender, fundamentalism, literal interpretism, beliefs about God's death penalty position, and perceptions of how one's religious group felt about the death penalty predicted death penalty sentencing verdicts. Future research could determine whether using peremptory challenges to exclude potential jurors based on religion can help lawyers choose a more favorable jury.

Correlates of death anxiety in Pakistan.

To ascertain the effect of gender, age, and religiosity on death anxiety, 132 participants were interviewed using Templer Death Anxiety Scale and Collett-Lester Fear of Death Scale (CLS). Women, older participants, and less religious participants were found to be more scared of their impending death. Gender effect was more pronounced, however, on the CLS. Women and less religious people reported to experience greater anxiety than their respective counterparts about different dimensions of death, for example, the shortness of life, total isolation of death, fear of not being, and disintegration of body after dying. The findings of the current work indicate that the general predictors of death anxiety, gender, age, and religiosity reported in Western, predominantly Christian samples also hold in an Eastern, Muslim sample.

Cell Death in C. elegans Development.

Science.gov (United States)

Malin, Jennifer Zuckerman; Shaham, Shai

2015-01-01

Cell death is a common and important feature of animal development, and cell death defects underlie many human disease states. The nematode Caenorhabditis elegans has proven fertile ground for uncovering molecular and cellular processes controlling programmed cell death. A core pathway consisting of the conserved proteins EGL-1/BH3-only, CED-9/BCL2, CED-4/APAF1, and CED-3/caspase promotes most cell death in the nematode, and a conserved set of proteins ensures the engulfment and degradation of dying cells. Multiple regulatory pathways control cell death onset in C. elegans, and many reveal similarities with tumor formation pathways in mammals, supporting the idea that cell death plays key roles in malignant progression. Nonetheless, a number of observations suggest that our understanding of developmental cell death in C. elegans is incomplete. The interaction between dying and engulfing cells seems to be more complex than originally appreciated, and it appears that key aspects of cell death initiation are not fully understood. It has also become apparent that the conserved apoptotic pathway is dispensable for the demise of the C. elegans linker cell, leading to the discovery of a previously unexplored gene program promoting cell death. Here, we review studies that formed the foundation of cell death research in C. elegans and describe new observations that expand, and in some cases remodel, this edifice. We raise the possibility that, in some cells, more than one death program may be needed to ensure cell death fidelity. © 2015 Elsevier Inc. All rights reserved.

Determination of death: Metaphysical and biomedical discourse

Directory of Open Access Journals (Sweden)

Irayda Jakušovaitė

2016-01-01

Full Text Available The prominence of biomedical criteria relying on brain death reduces the impact of metaphysical, anthropological, psychosocial, cultural, religious, and legal aspects disclosing the real value and essence of human life. The aim of this literature review is to discuss metaphysical and biomedical approaches toward death and their complimentary relationship in the determination of death. A critical appraisal of theoretical and scientific evidence and legal documents supported analytical discourse. In the metaphysical discourse of death, two main questions about what human death is and how to determine the fact of death clearly separate the ontological and epistemological aspects of death. During the 20th century, various understandings of human death distinguished two different approaches toward the human: the human is a subject of activities or a subject of the human being. Extinction of the difference between the entities and the being, emphasized as rational–logical instrumentation, is not sufficient to understand death thoroughly. Biological criteria of death are associated with biological features and irreversible loss of certain cognitive capabilities. Debating on the question “Does a brain death mean death of a human being?” two approaches are considering: the body-centrist and the mind-centrist. By bridging those two alternatives human death appears not only as biomedical, but also as metaphysical phenomenon. It was summarized that a predominance of clinical criteria for determination of death in practice leads to medicalization of death and limits the holistic perspective toward individual's death. Therefore, the balance of metaphysical and biomedical approaches toward death and its determination would decrease the medicalization of the concept of death.

Menadione triggers cell death through ROS-dependent mechanisms involving PARP activation without requiring apoptosis.

Low levels of reactive oxygen species (ROS) can function as redox-active signaling messengers, whereas high levels of ROS induce cellular damage. Menadione generates ROS through redox cycling, and high concentrations trigger cell death. Previous work suggests that menadione triggers cytochrome c release from mitochondria, whereas other studies implicate the activation of the mitochondrial permeability transition pore as the mediator of cell death. We investigated menadione-induced cell death in genetically modified cells lacking specific death-associated proteins. In cardiomyocytes, oxidant stress was assessed using the redox sensor RoGFP, expressed in the cytosol or the mitochondrial matrix. Menadione elicited rapid oxidation in both compartments, whereas it decreased mitochondrial potential and triggered cytochrome c redistribution to the cytosol. Cell death was attenuated by N-acetylcysteine and exogenous glutathione or by overexpression of cytosolic or mitochondria-targeted catalase. By contrast, no protection was observed in cells overexpressing Cu,Zn-SOD or Mn-SOD. Overexpression of antiapoptotic Bcl-X(L) protected against staurosporine-induced cell death, but it failed to confer protection against menadione. Genetic deletion of Bax and Bak, cytochrome c, cyclophilin D, or caspase-9 conferred no protection against menadione-induced cell death. However, cells lacking PARP-1 showed a significant decrease in menadione-induced cell death. Thus, menadione induces cell death through the generation of oxidant stress in multiple subcellular compartments, yet cytochrome c, Bax/Bak, caspase-9, and cyclophilin D are dispensable for cell death in this model. These studies suggest that multiple redundant cell death pathways are activated by menadione, but that PARP plays an essential role in mediating each of them. Copyright © 2010 Elsevier Inc.

Background Indonesia provides the largest single source of pilgrims for the Hajj (10%). In the last two decades, mortality rates for Indonesian pilgrims ranged between 200–380 deaths per 100,000 pilgrims over the 10-week Hajj period. Reasons for high mortality are not well understood. In 2008, verbal autopsy was introduced to complement routine death certificates to explore cause of death diagnoses. This study presents the patterns and causes of death for Indonesian pilgrims, and compares routine death certificates to verbal autopsy findings. Methods Public health surveillance was conducted by Indonesian public health authorities accompanying pilgrims to Saudi Arabia, with daily reporting of hospitalizations and deaths. Surveillance data from 2008 were analyzed for timing, geographic location and site of death. Percentages for each cause of death category from death certificates were compared to that from verbal autopsy. Results In 2008, 206,831 Indonesian undertook the Hajj. There were 446 deaths, equivalent to 1,968 deaths per 100,000 pilgrim years. Most pilgrims died in Mecca (68%) and Medinah (24%). There was no statistically discernible difference in the total mortality risk for the two pilgrimage routes (Mecca or Medinah first), but the number of deaths peaked earlier for those traveling to Mecca first (p=0.002). Most deaths were due to cardiovascular (66%) and respiratory (28%) diseases. A greater proportion of deaths were attributed to cardiovascular disease by death certificate compared to the verbal autopsy method (pIndonesian pilgrim mortality rates were very high. Correct classification of cause of death is critical for the development of risk mitigation strategies. Since verbal autopsy classified causes of death differently to death certificates, further studies are needed to assess the method’s utility in this setting. PMID:23991182

Sudden unexpected death in epilepsy (SUDEP) is associated with the high premature mortality observed among people with epilepsy. It is, however, considered a rare event in China, probably because of lack of awareness and limitation of studies in the country. We aimed to provide some initial estimation of the burden of SUDEP in China. We established a large Chinese community-based cohort of people with epilepsy between January 2010 and December 2011. For any participant who died during follow-up, detailed information on cause of death was obtained using a specifically designed Verbal Autopsy Questionnaire. All cases were reviewed by a multidisciplinary expert panel and reinvestigated if necessary. Sudden unexpected death in epilepsy incidence rates were estimated and case details provided. The cohort consisted of 1562 people and during a median 5years follow-up, 72 deaths were reported. The all-causes death incidence was 11.23 (95% CI 8.86-14.07) per 1000 person-years. Fifteen died suddenly and unexpectedly in a reasonable state of health in the week preceding death. We recorded detailed information of these 15 deaths. Thirteen were considered to be probable SUDEP and two possible SUDEP. The incidence of probable SUDEP was 2.03 (95% CI 1.13-3.38) per 1000 person-years, and the incidence of all suspected (probable and possible) SUDEP was 2.34 (95% CI 1.36-3.77) per 1000 person-years. The incidence of SUDEP was relatively high among Chinese people with epilepsy when compared with that in previous community-based studies from high-income countries. The burden of SUDEP in China requires further assessments. Copyright © 2017 Elsevier Inc. All rights reserved.

Accidental drug deaths in Fulton County, Georgia, 2002: characteristics, case management and certification issues.

Graham, Jason K; Hanzlick, Randy

2008-09-01

cocaine-related deaths were considered to be of "low suspicion" for drug involvement at the time the death was reported to the medical examiner with the remaining 62% being of "high suspicion". Autopsy rates were somewhat lower in the low suspicion group (67%) versus the high suspicion group (72%). Comparison of drug levels between cocaine-related death certification groups was performed. No statistically significant difference was shown in drug levels (cocaine, P > 0.3; benzoylecgonine, P > 0.2) between deaths certified as cocaine toxicity versus those certified as cocaine-complicating disease or causing adverse event. In Fulton County, accidental drug deaths in 2002 most often involved cocaine either alone or in combination with opiates and/or alcohol. Cocaine, opiates, or both were involved in greater than three-fourths (77%) of all drug-related deaths. The majority of all decedents were black (57%) and male (76%) with an average age of 42.2 years. Cocaine and ethanol were more frequently detected in black decedents, whereas opiates and polydrug abuse were more common in white decedents throughout the period studied. Preliminary investigation showed a high index of suspicion for the specific drug involved in virtually all opiate and alcohol cases, and in 62% of cocaine-related cases. Overall, the 100 accidental drug deaths in 2002 accounted for 7.5% of all deaths investigated and certified by the Fulton County Medical Examiner's Office. Our study provides further evidence to support the lack of correlation between serum drug levels and the mechanism of drug toxicity in cocaine-related deaths. No statistically significant differences were shown in parent cocaine or benzoylecgonine concentrations between those cases certified as toxicities or poisonings versus those cases certified as aggravating underlying disease or causing an adverse event. In addition, 62% of the cocaine-related death cases were considered initially to be of high suspicion for drug-related death

The life expectancies and causes of death were evaluated in 299,555 dogs insured in Japan between 1 April 2010 and 31 March 2011, of which 4169 dogs died during this period. The overall life expectancy of dogs was 13.7 years. The probability of death was high in the first year of life, lowest in the second and third years, and increased exponentially after 3 years of age. The life expectancy was 13.8 years in the death increased as dogs got older for most potential causes of death. Neoplasia resulted in the highest probability of death, especially in the large and giant breed groups. Cardiovascular system disorders were the second major cause of death and the toy group had a probability of death significantly higher than the other breed groups at age 12+.

Death certificates (DC) can provide valuable health status data regarding disease incidence, prevalence and mortality in a community. It can guide local health policy and help in setting priorities. Incomplete and inaccurate DC data, on the other hand, can significantly impair the precision of a national health information database. In this study we evaluated the accuracy of death certificates at a tertiary care teaching hospital in a Karachi, Pakistan. A retrospective study conducted at Aga Khan University Hospital, Karachi, Pakistan for a period of six months. Medical records and death certificates of all patients who died under adult medical service were studied. The demographic characteristics, administrative details, co-morbidities and cause of death from death certificates were collected using an approved standardized form. Accuracy of this information was validated using their medical records. Errors in the death certificates were classified into six categories, from 0 to 5 according to increasing severity; a grade 0 was assigned if no errors were identified, and 5, if an incorrect cause of death was attributed or placed in an improper sequence. 223 deaths occurred during the study period. 9 certificates were not accessible and 12 patients had incomplete medical records. 202 certificates were finally analyzed. Most frequent errors pertaining to patients' demographics (92%) and cause/s of death (87%) were identified. 156 (77%) certificates had 3 or more errors and 124 (62%) certificates had a combination of errors that significantly changed the death certificate interpretation. Only 1% certificates were error free. A very high rate of errors was identified in death certificates completed at our academic institution. There is a pressing need for appropriate intervention/s to resolve this important issue.

[Death and the pop musician].

Science.gov (United States)

de Leeuw, Peter W

2011-01-01

Many people are inclined to believe that popular music artists are prone to die prematurely. Scientific research into this matter is scarce. There is only one epidemiological study on this subject, showing that mortality among pop stars during the first 25 years after they became famous is increased. This mortality is higher in Northern America than it is in Europe, but European pop stars die on average at an earlier age. A fairly common belief states that many pop stars die at the age of 27 years. This age has even been proclaimed as the most critical for modern musicians. However, data of several hundred deceased pop stars shows no evidence for increased mortality at the age of 27. Moreover, the data suggests that the age of death has increased over the past forty years. As far as the cause of death is concerned, overdose of drugs or alcohol rank highly next to cardiovascular disease and malignancy.

The prominence of biomedical criteria relying on brain death reduces the impact of metaphysical, anthropological, psychosocial, cultural, religious, and legal aspects disclosing the real value and essence of human life. The aim of this literature review is to discuss metaphysical and biomedical approaches toward death and their complimentary relationship in the determination of death. A critical appraisal of theoretical and scientific evidence and legal documents supported analytical discourse. In the metaphysical discourse of death, two main questions about what human death is and how to determine the fact of death clearly separate the ontological and epistemological aspects of death. During the 20th century, various understandings of human death distinguished two different approaches toward the human: the human is a subject of activities or a subject of the human being. Extinction of the difference between the entities and the being, emphasized as rational-logical instrumentation, is not sufficient to understand death thoroughly. Biological criteria of death are associated with biological features and irreversible loss of certain cognitive capabilities. Debating on the question "Does a brain death mean death of a human being?" two approaches are considering: the body-centrist and the mind-centrist. By bridging those two alternatives human death appears not only as biomedical, but also as metaphysical phenomenon. It was summarized that a predominance of clinical criteria for determination of death in practice leads to medicalization of death and limits the holistic perspective toward individual's death. Therefore, the balance of metaphysical and biomedical approaches toward death and its determination would decrease the medicalization of the concept of death.

Background For the pending National Claims Database in Japan, researchers will not have access to death information in the enrollment files. We developed and evaluated a claims-based definition of death. Methodology/Principal Findings We used healthcare claims and enrollment data between January 2005 and August 2009 for 195,193 beneficiaries aged 20 to 74 in 3 private health insurance unions. We developed claims-based definitions of death using discharge or disease status and Charlson comorbidity index (CCI). We calculated sensitivity, specificity and positive predictive values (PPVs) using the enrollment data as a gold standard in the overall population and subgroups divided by demographic and other factors. We also assessed bias and precision in two example studies where an outcome was death. The definition based on the combination of discharge/disease status and CCI provided moderate sensitivity (around 60%) and high specificity (99.99%) and high PPVs (94.8%). In most subgroups, sensitivity of the preferred definition was also around 60% but varied from 28 to 91%. In an example study comparing death rates between two anticancer drug classes, the claims-based definition provided valid and precise hazard ratios (HRs). In another example study comparing two classes of anti-depressants, the HR with the claims-based definition was biased and had lower precision than that with the gold standard definition. Conclusions/Significance The claims-based definitions of death developed in this study had high specificity and PPVs while sensitivity was around 60%. The definitions will be useful in future studies when used with attention to the possible fluctuation of sensitivity in some subpopulations. PMID:23741526

Distributed user interfaces for clinical ubiquitous computing applications.

2005-08-01

Ubiquitous computing with multiple interaction devices requires new interface models that support user-specific modifications to applications and facilitate the fast development of active workspaces. We have developed NOSTOS, a computer-augmented work environment for clinical personnel to explore new user interface paradigms for ubiquitous computing. NOSTOS uses several devices such as digital pens, an active desk, and walk-up displays that allow the system to track documents and activities in the workplace. We present the distributed user interface (DUI) model that allows standalone applications to distribute their user interface components to several devices dynamically at run-time. This mechanism permit clinicians to develop their own user interfaces and forms to clinical information systems to match their specific needs. We discuss the underlying technical concepts of DUIs and show how service discovery, component distribution, events and layout management are dealt with in the NOSTOS system. Our results suggest that DUIs--and similar network-based user interfaces--will be a prerequisite of future mobile user interfaces and essential to develop clinical multi-device environments.

Gender differences in drunk driving prevalence rates and trends: a 20-year assessment using multiple sources of evidence.

Schwartz, Jennifer

2008-09-01

This research tracked women's and men's drunk driving rates and the DUI sex ratio in the United States from 1982-2004 using three diverse sources of evidence. Sex-specific prevalence estimates and the sex ratio are derived from official arrest statistics from the Federal Bureau of Investigation, self-reports from the Centers for Disease Control and Prevention, and traffic fatality data from the National Highway and Transportation Safety Administration. Drunk driving trends were analyzed using Augmented Dickey Fuller time series techniques. Female DUI arrest rates increased whereas male rates declined then stabilized, producing a significantly narrower sex ratio. According to self-report and traffic data, women's and men's drunk driving rates declined and the gender gap was unchanged. Women's overrepresentation in arrests relative to their share of offending began in the 1990s and accelerated in 2000. Women's arrest gains, contrasted with no systematic change in DUI behavior, and the timing of this shift suggest an increased vulnerability to arrest. More stringent laws and enforcement directed at less intoxicated offenders may inadvertently target female offending patterns.

Elements of healthy death: a thematic analysis.

Estebsari, Fatemeh; Taghdisi, Mohammad Hossein; Mostafaei, Davood; Rahimi, Zahra

2017-01-01

Background: Death is a natural and frightening phenomenon, which is inevitable. Previous studies on death, which presented a negative and tedious image of this process, are now being revised and directed towards acceptable death and good death. One of the proposed terms about death and dying is "healthy death", which encourages dealing with death positively and leading a lively and happy life until the last moment. This study aimed to explain the views of Iranians about the elements of healthy death. Methods: This qualitative study was conducted for 12 months in two general hospitals in Tehran (capital of Iran), using the thematic analysis method. After conducting 23 in-depth interviews with 21 participants, transcription of content, and data immersion and analysis, themes, as the smallest meaningful units were extracted, encoded and classified. Results: One main category of healthy death with 10 subthemes, including dying at the right time, dying without hassle, dying without cost, dying without dependency and control, peaceful death, not having difficulty at dying, not dying alone and dying at home, inspired death, preplanned death, and presence of a clergyman or a priest, were extracted as the elements of healthy death from the perspective of the participants in this study. Conclusion: The study findings well explained the elements of healthy death. Paying attention to the conditions and factors causing healthy death by professionals and providing and facilitating quality services for patients in the end stage of life make it possible for patients to experience a healthy death.

Causes and prevention of sudden cardiac death in the elderly.

Science.gov (United States)

Tung, Patricia; Albert, Christine M

2013-03-01

Sudden cardiac death (SCD) is a major cause of mortality in elderly individuals owing to a high prevalence of coronary heart disease, systolic dysfunction, and congestive heart failure (CHF). Although the incidence of SCD increases with age, the proportion of cardiac deaths that are sudden decreases owing to high numbers of other cardiac causes of death in elderly individuals. Implantable cardioverter-defibrillator (ICD) therapy has been demonstrated to improve survival and prevent SCD in selected patients with systolic dysfunction and CHF. However, ICD therapy in elderly patients might not be effective because of a greater rate of pulseless electrical activity underlying SCD and other competing nonarrhythmic causes of death in this population. Although under-represented in randomized trials of ICD use, elderly patients comprise a substantial proportion of the population that qualifies for and receives an ICD for primary prevention under current guidelines. Cardiac resynchronization therapy (CRT), which has been demonstrated to reduce mortality in selected populations with heart failure, is also more commonly used in this group of patients than in younger individuals. In this Review, we examine the causes of SCD in elderly individuals, and discuss the existing evidence for effectiveness of ICD therapy and CRT in this growing population.

Marom, Tal; Cinamon, Udi; Castellanos, Paul F; Cohen, Marta C

2012-03-01

Sudden infant death syndrome (SIDS) is characterized by the sudden death of an apparently otherwise healthy infant, typically during sleep, and with no obvious case after a thorough post-mortem and scene death examination. To address the problem from the otolaryngologist's perspective, describe relevant pathologies, discuss controversies and suggest preventive measures in high-risk populations. A MEDLINE search and hand search were conducted to identify reports published between 1969 and 2011 in the English language on the pathophysiology of SIDS related to the head and neck organs. Search terms included SIDS (MeSH term), SIDS and pathophysiology (text words), and SIDS and autopsy (text words). A growing number of reports suggested head and neck organs involvement in SIDS autopsies. Laryngeal, oropharyngeal, maxillofacial, otologic, cervical vascular abnormalities and infectious etiologies, were recognized and discussed. Otolaryngologists should be aware of relevant pathologies, as some are treatable, if identified early enough in infancy. A proactive risk-management approach is warranted in infants presenting with certain abnormalities reviewed here. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Public education and misinformation on brain death in mainstream media.

Science.gov (United States)

Lewis, Ariane; Lord, Aaron S; Czeisler, Barry M; Caplan, Arthur

2016-09-01

We sought to evaluate the caliber of education mainstream media provides the public about brain death. We reviewed articles published prior to July 31, 2015, on the most shared/heavily trafficked mainstream media websites of 2014 using the names of patients from two highly publicized brain death cases, "Jahi McMath" and "Marlise Muñoz." We reviewed 208 unique articles. The subject was referred to as being "alive" or on "life support" in 72% (149) of the articles, 97% (144) of which also described the subject as being brain dead. A definition of brain death was provided in 4% (9) of the articles. Only 7% (14) of the articles noted that organ support should be discontinued after brain death declaration unless a family has agreed to organ donation. Reference was made to well-known cases of patients in persistent vegetative states in 16% (34) of articles and 47% (16) of these implied both patients were in the same clinical state. Mainstream media provides poor education to the public on brain death. Because public understanding of brain death impacts organ and tissue donation, it is important for physicians, organ procurement organizations, and transplant coordinators to improve public education on this topic. © 2016 John Wiley & Sons A/S.

Methods for determining time of death.

Science.gov (United States)

Madea, Burkhard

2016-12-01

Medicolegal death time estimation must estimate the time since death reliably. Reliability can only be provided empirically by statistical analysis of errors in field studies. Determining the time since death requires the calculation of measurable data along a time-dependent curve back to the starting point. Various methods are used to estimate the time since death. The current gold standard for death time estimation is a previously established nomogram method based on the two-exponential model of body cooling. Great experimental and practical achievements have been realized using this nomogram method. To reduce the margin of error of the nomogram method, a compound method was developed based on electrical and mechanical excitability of skeletal muscle, pharmacological excitability of the iris, rigor mortis, and postmortem lividity. Further increasing the accuracy of death time estimation involves the development of conditional probability distributions for death time estimation based on the compound method. Although many studies have evaluated chemical methods of death time estimation, such methods play a marginal role in daily forensic practice. However, increased precision of death time estimation has recently been achieved by considering various influencing factors (i.e., preexisting diseases, duration of terminal episode, and ambient temperature). Putrefactive changes may be used for death time estimation in water-immersed bodies. Furthermore, recently developed technologies, such as H magnetic resonance spectroscopy, can be used to quantitatively study decompositional changes. This review addresses the gold standard method of death time estimation in forensic practice and promising technological and scientific developments in the field.

Deaths in New York City Jails, 2001–2009

Approximately 90 000 inmates are admitted annually to the New York City jail system, many of whom require a high level of medical or mental health services. According to our analysis of deaths in custody from 2001 to 2009, crude death rates have dropped significantly despite the increasing age of the population. Falling HIV-related mortality appears to contribute to this change. Other observations include low rates of suicide across all 9 years and increasing age of the population in recent years.

Anderson, Natalie Elizabeth; Kent, Bridie; Owens, R Glynn

Death and dying are inevitable life encounters, but a nurse's first experience with patient death may pose considerable cognitive, emotional and clinical challenges. This paper reports the findings of the second phase of a study; the first has been reported elsewhere. This phase explored the earliest memorable patient death experiences of New Zealand registered nurses. A purposeful, self-selected sub-sample of a larger study of New Zealand registered nurses, took part in individual face-to-face semi-structured interviews. Interpretative phenomenological analysis was utilised to seek to understand participants' experiences. Thematic analysis was undertaken to identify emerging themes, with participants' own words used as theme headings, where their phrases provided succinct or powerful descriptors. A diverse participant group of twenty, currently practising, New Zealand registered nurses provided rich and detailed descriptions of their earliest memorable experience with patient death. Participants from a variety of training backgrounds described patient deaths, which occurred in a range of settings - some only a few months prior, others - more than thirty years ago. Seven emergent themes, and features of more positive, or negative experiences were identified: Event Significance; Emotional Challenges; Sharing the Experience; Learning; Feeling Unprepared, Responses to Death and Finding Benefits. For participants in this study, there was considerable evidence that their earliest memorable patient death was a significant event. Furthermore, although most participants' experiences were characterised by emphatic or poignant description, there was most often a balance of challenges and rewards. Copyright © 2014 Elsevier Ltd.

Sudden unexpected death in infancy: place and time of death.

Glasgow, J F T; Thompson, A J; Ingram, P J

2006-01-01

In recent years, many babies who die of Sudden Unexpected Death in Infancy (SUDI) in Northern Ireland are found dead in bed--i.e. co-sleeping--with an adult. In order to assess its frequency autopsy reports between April 1996 and August 2001 were reviewed and linked to temporal factors. The day and month of death, and the place where the baby was found were compared to a reference population of infant deaths between one week of age and the second birthday. Although the rate of SUDI was lower than the UK average, 43 cases of SUDI were identified, and two additional deaths with virtually identical autopsy findings that were attributed to asphyxia caused by suffocation due to overlaying. Thirty-two of the 45 (71%) were less than four months of age. In 30 of the 45 cases (67%) the history stated that the baby was bed sharing with others; 19 died sleeping in an adult bed, and 11 on a sofa or armchair. In 16 of the 30 (53%) there were at least two other people sharing the sleeping surface, and in one case, three. SUDI was twice as frequent at weekends (found dead Saturday-Monday mornings) compared to weekdays (psharing a place of sleep per se may not increase the risk of death, our findings may be linked to factors such as habitual smoking, consumption of alcohol or illicit drugs as reported in case-control studies. In advising parents on safer childcare practices, health professionals must be knowledgeable of current research and when, for example, giving advice on co-sleeping this needs to be person-specific cognisant of the risks within a household. New and better means of targeting such information needs to be researched if those with higher risk life-styles are to be positively influenced.

Violent deaths of media workers associated with conflict in Iraq, 2003–2012

Full Text Available Background. The violent deaths of media workers is a critical issue worldwide, especially in areas of political and social instability. Such deaths can be a particular concern as they may undermine the development and functioning of an open and democratic society.Method. Data on the violent deaths of media workers in Iraq for ten years (2003–2012 were systematically collated from five international databases. Analyses included time trends, weapons involved, nationality of the deceased, outcome for perpetrators and location of death.Results. During this ten-year period, there were 199 violent deaths of media workers in Iraq. The annual number increased substantially after the invasion in 2003 (peaking at n = 47 in 2007 and then declined (n = 5 in 2012. The peak years (2006–2007 for these deaths matched the peak years for estimated violent deaths among civilians. Most of the media worker deaths (85% were Iraqi nationals. Some were killed whilst on assignment in the field (39% and 28% involved a preceding threat. Common perpetrators of the violence were: political groups (45%, and coalition forces (9%, but the source of the violence was often unknown (29%. None of the perpetrators have subsequently been prosecuted (as of April 2014. For each violent death of a media worker, an average of 3.1 other people were also killed in the same attack (range 0–100 other deaths.Discussion. This analysis highlights the high number of homicides of media workers in Iraq in this conflict period, in addition to the apparently total level of impunity. One of the potential solutions may be establishing a functioning legal system that apprehends offenders and puts them on trial. The relatively high quality of data on violent deaths in this occupational group, suggests that it could act as one sentinel population within a broader surveillance system of societal violence in conflict zones.

Despite the level of supervision of inmates on death row, their suicide rate is higher than both the male prison population in the United States and the population of males over the age of 14 in free society. This study presents suicide data for death row inmates from 1978 through 2010. For the years 1978 through 2010, suicide rates on death row were higher than that for the general population of males over the age of 15 and for state prisons for all but 2 years. © 2016 American Academy of Forensic Sciences.

Apoptosis is the primary means for eliminating unwanted cells in multicellular organisms in order to preserve tissue homeostasis and function. It is characterized by distinct changes in the morphology of the dying cell that are orchestrated by a series of discrete biochemical events. Although there is evidence of primitive forms of programmed cell death also in prokaryotes, no information is available to suggest that prokaryotic death displays mechanistic similarities to the highly regulated programmed death of eukaryotic cells. In this study we compared the characteristics of tumor and bacterial cell death induced by HAMLET, a human milk complex of alpha-lactalbumin and oleic acid. We show that HAMLET-treated bacteria undergo cell death with mechanistic and morphologic similarities to apoptotic death of tumor cells. In Jurkat cells and Streptococcus pneumoniae death was accompanied by apoptosis-like morphology such as cell shrinkage, DNA condensation, and DNA degradation into high molecular weight fragments of similar sizes, detected by field inverse gel electrophoresis. HAMLET was internalized into tumor cells and associated with mitochondria, causing a rapid depolarization of the mitochondrial membrane and bound to and induced depolarization of the pneumococcal membrane with similar kinetic and magnitude as in mitochondria. Membrane depolarization in both systems required calcium transport, and both tumor cells and bacteria were found to require serine protease activity (but not caspase activity) to execute cell death. Our results suggest that many of the morphological changes and biochemical responses associated with apoptosis are present in prokaryotes. Identifying the mechanisms of bacterial cell death has the potential to reveal novel targets for future antimicrobial therapy and to further our understanding of core activation mechanisms of cell death in eukaryote cells.

Cardiovascular causes of maternal sudden death. Sudden arrhythmic death syndrome is leading cause in UK.

This study aims to determine the causes of sudden cardiac death during pregnancy and in the postpartum period and patients' characteristics. There are few studies in the literature. Eighty cases of sudden unexpected death due to cardiac causes in relation to pregnancy and postpartum period in a database of 4678 patients were found and examined macroscopically and microscopically. The mean age was 30±7 years with a range from 16 to 43 years. About 30% were 35 years old or older; 50% of deaths occurred during pregnancy and 50% during the postpartum period. About 59.18% were obese or overweight where body mass index data were available. The leading causes of death were sudden arrhythmic death syndrome (SADS) (53.75%) and cardiomyopathies (13.80%). Other causes include dissection of aorta or its branches (8.75%), congenital heart disease (2.50%) and valvular disease (3.75%). This study highlights sudden cardiac death in pregnancy or in the postpartum period, which is mainly due to SADS with underlying channelopathies and cardiomyopathy. We wish to raise awareness of these frequently under-recognised entities in maternal deaths and the need of cardiological screening of the family as a result of the diagnosis.

A law recognizing brain death is a life saving legal measure in patients suffering from badly diseased organs such as kidney, liver, heart, and lung. Such law is being discussed for legalization at the Korean National Assembly. There are various criteria used for brain death in western world and brain scintiscan is one of them. However, the scintiscan is not considered in establishing brain death in the draft of the law. The purpose of this report is to spread this technique in nuclear medicine society as well as in other medical societies. We evaluated 7 patients with clinical suspicion of brain death by various causes. The patient's age ranged from 5 to 39 years. We used 5-20mCi 99m Tc-HMPAO (d.1-hexamethyl propylene amine oxime) or ECD (Ethyl Cysteinate Dimer), lipophilic agents that cross BBB (blood brain barrier). A dynamic study followed by static or SPECT (single photon emission tomography) was performed. Interpretive criteria used for brain death were 1) no intracranial circulation 2) no brain uptake. The second criteria is heavily used. Five of 7 patients were scintigraphically brain dead and the remaining 2 had some brain uptake excluding the diagnosis of scintigraphic brain death. In conclusion, cerebral perfusion study using a lipophilic brain tracer offers a noninvasive, rapid, easy, accurate and reliable mean in the diagnosis of brain death. We believe that this modality should be included in the criteria of brain death in the draft of the proposed Korean law

In the last months of the second World War, 250,000 German refugees landed in Denmark. A third of them were children under the age of 15. Seven thousand German refugee children under the age of five died in Denmark in 1945. Using birth certificates and death certificates from the Danish national archives and burial lists from the German refugee cemetaries I have collected data to reveal causes of death, age distributions and time of the deaths of the 7000 fatal cases among children under the age of five. Three thousand children under the age of one, 2000 children one year old and 2000 children 2-4 years old died. Most of them died just before and after the German surrender, but many died in the months following the German surrender. The infant mortality was extremely high all during 1945. The infants died from diseases due to malnutrition, but the older the children the more likely the causes of death were due to infectious diseases such as pneumonia, measles, diphtheria and gastroenteritis.

Over the period 2010-2012, maternal mortality from infectious causes accounted for 5% of maternal deaths by direct causes and 16% of maternal deaths by indirect causes. Among the 22 deaths caused by infection occurred during this period, 6 deaths were attributed to direct causes from genital tract origin, confirming thus the decrease in direct maternal deaths by infection during the last ten years. On the contrary, indirect maternal deaths by infection, from extragenital origin, doubled during the same period, with 16 deaths in the last triennium, dominated by winter respiratory infections, particularly influenza: the 2009-2010 influenza A (H1N1) virus pandemic was the leading cause of indirect maternal mortality by infection during the studied period. The main infectious agents involved in maternal deaths from direct causes were Streptococcus A, Escherichia Coli and Clostridium perfringens: these bacterias were responsible for toxic shock syndrome, severe sepsis, secondary in some cases to cellulitis or necrotizing fasciitis. Of the 6 deaths due to direct infection, 4 were considered avoidable because of inadequate management: delayed or missed diagnosis, delayed or inadequate initiation of a specific medical and/or surgical treatment. Of the 16 indirect maternal deaths due to infection causes, the most often involved infectious agents were influenza A (H1N1) virus and Streptococcus pneumonia with induced purpura fulminans: the absence of influenza vaccination during pregnancy, delayed diagnosis and emergency initiation of a specific treatment, were the main contributory factors to these deaths and their avoidability in 70% of the cases analyzed.

Current asthma deaths among adults in Japan

Directory of Open Access Journals (Sweden)

Tsugio Nakazawa

2004-01-01

Full Text Available Recent asthma deaths were examined from yearly reports of the Ministry of Health, Labor and Welfare of Japan and from reports published by the Japan Asthma Death Investigation Committee on 811 deaths over the period 1992–2000. The rate and number of recent asthma deaths in Japan have been decreasing rapidly. Most asthma deaths were of patients aged 70–90 years and there has been a marked trend for increased asthma deaths in the elderly. As for the circumstances surrounding the deaths, sudden death, unstable sudden aggravation and intermittent aggravation were mainly noted. Respiratory infections, fatigue and stress were the major courses of fatal attacks contributing to deaths due to asthma. Many of the patients who died from asthma had been diagnosed as having as moderate to severe asthma and many had non-atopic asthma. There are some reports that suggest that the recent decrease in asthma deaths in Japan is correlated with the use of inhaled cortico- steroids.

Burnout After Patient Death: Challenges for Direct Care Workers.

Science.gov (United States)

Boerner, Kathrin; Gleason, Hayley; Jopp, Daniela S

2017-09-01

Direct care workers in long-term care can develop close relationships with their patients and subsequently experience significant grief after patient death. Consequences of this experience for employment outcomes have received little attention. To investigate staff, institutional, patient, and grief factors as predictors of burnout dimensions among direct care workers who had experienced recent patient death; determine which specific aspects of these factors are of particular importance; and establish grief as an independent predictor of burnout dimensions. Participants were 140 certified nursing assistants and 80 homecare workers who recently experienced patient death. Data collection involved comprehensive semistructured in-person interviews. Standardized assessments and structured questions addressed staff, patient, and institutional characteristics, grief symptoms and grief avoidance, as well as burnout dimensions (depersonalization, emotional exhaustion, and personal accomplishment). Hierarchical regressions revealed that grief factors accounted for unique variance in depersonalization, over and above staff, patient, and institutional factors. Supervisor support and caregiving benefits were consistently associated with higher levels on burnout dimensions. In contrast, coworker support was associated with a higher likelihood of depersonalization and emotional exhaustion. Findings suggest that grief over patient death plays an overlooked role in direct care worker burnout. High supervisor support and caregiving benefits may have protective effects with respect to burnout, whereas high coworker support may constitute a reflection of burnout.

Mortality and causes of death from death certificates were analyzed among workers exposed to phosgene while working at a uranium-processing plant in Tennessee in 1943-45. Standardized mortality ratios (SMRs) were calculated by using death rates for U.S. white males. As of 1979, SMRs for all causes and for various selected causes were similar in 694 male chemical workers chronically exposed to low levels of phosgene in 1943-45 and in 9280 male controls who worked at the same plant. SMRs for diseases of the respiratory system were 107 (14 observed vs. 13.07 expected) in the chemical workers and 119 (292 observed vs. 245.75 expected) in the controls. In a group of 106 males who were acutely exposed to high levels of phosgene, there were 41 deaths observed vs. 33.87 expected (SMR = 121; 95% confidence limits = 86 and 165). One death, occurring within 24 hours of exposure, was from pulmonary edema due to phosgene poisoning (coded to accidental causes). Five deaths were coded to diseases of the respiratory system (SMR = 266; 95% CL = 86 and 622); in 2 of these 5 deaths, bronchitis due to phosgene exposure had been reported in 1945. Among 91 female workers with acute high-level phosgene exposure, frequencies of symptoms and early health effects (pneumonitis and bronchitis) differed from those reported for the 106 male cases; preliminary data on vital status of these females are too incomplete for analysis, and further follow-up is needed

The causes of death in dementia are not established, particularly in rarer dementias. The aim of this study is to calculate risk of death from specific causes for a broader spectrum of dementia diagnoses. Cohort study. Swedish Dementia Registry (SveDem), 2007-2012. Individuals with incident dementia registered in SveDem (N = 28,609); median follow-up 741 days. Observed deaths were 5,368 (19%). Information on number of deaths and causes of mortality was obtained from death certificates. Odds ratios for the presence of dementia on death certificates were calculated. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox hazards regression for cause-specific mortality, using Alzheimer's dementia (AD) as reference. Hazard ratios for death for each specific cause of death were compared with hazard ratios of death from all causes (P-values from t-tests). The most frequent underlying cause of death in this cohort was cardiovascular (37%), followed by dementia (30%). Dementia and cardiovascular causes appeared as main or contributory causes on 63% of certificates, followed by respiratory (26%). Dementia was mentioned less in vascular dementia (VaD; 57%). Compared to AD, cardiovascular mortality was higher in individuals with VaD than in those with AD (HR = 1.82, 95% CI = 1.64-2.02). Respiratory death was higher in individuals with Lewy body dementia (LBD, including Parkinson's disease dementia and dementia with Lewy bodies, HR = 2.16, 95% CI = 1.71-2.71), and the risk of respiratory death was higher than expected from the risk for all-cause mortality. Participants with frontotemporal dementia were more likely to die from external causes of death than those with AD (HR = 2.86, 95% CI = 1.53-5.32). Dementia is underreported on death certificates as main and contributory causes. Individuals with LBD had a higher risk of respiratory death than those with AD. © 2016 The Authors.

Full Text Available Beatriz Jáuregui-Garrido1, Ignacio Jáuregui-Lobera2,31Department of Cardiology, University Hospital Virgen del Rocío, 2Behavioral Sciences Institute, 3Pablo de Olavide University, Seville, SpainAbstract: Eating disorders are usually associated with an increased risk of premature death with a wide range of rates and causes of mortality. “Sudden death” has been defined as the abrupt and unexpected occurrence of fatality for which no satisfactory explanation of the cause can be ascertained. In many cases of sudden death, autopsies do not clarify the main cause. Cardiovascular complications are usually involved in these deaths. The purpose of this review was to report an update of the existing literature data on the main findings with respect to sudden death in eating disorders by means of a search conducted in PubMed. The most relevant conclusion of this review seems to be that the main causes of sudden death in eating disorders are those related to cardiovascular complications. The predictive value of the increased QT interval dispersion as a marker of sudden acute ventricular arrhythmia and death has been demonstrated. Eating disorder patients with severe cardiovascular symptoms should be hospitalized. In general, with respect to sudden death in eating disorders, some findings (eg, long-term eating disorders, chronic hypokalemia, chronically low plasma albumin, and QT intervals >600 milliseconds must be taken into account, and it must be highlighted that during refeeding, the adverse effects of hypophosphatemia include cardiac failure. Monitoring vital signs and performing electrocardiograms and serial measurements of plasma potassium are relevant during the treatment of eating disorder patients.Keywords: sudden death, cardiovascular complications, refeeding syndrome, QT interval, hypokalemia

Concept of death in young people with intellectual disability: a contribution to the pedagogy on death

Directory of Open Access Journals (Sweden)

Pablo RODRÍGUEZ HERRERO

2015-03-01

Full Text Available Despite being an essential human condition, death is an under-researched area in the effort to improve people with intellectual disabilities’ life quality. In this article we describe the concept of death among young people with intellectual disabilities. A mixed research methodology that includes quantitative and qualitative approaches was employed, including both a questionnaire and a semi-structured interview. Results indicate that participants have difficulty understanding of biological dimensions of death. Moreover, it has been found that participants present a wide range of opinions, attitudes and beliefs about death. Conclusions reflect on implications of these results for a possible pedagogy on death in young adults that would include accompaniment during bereavement.

To clarify the necessity for and problems related to autopsy for determining the cause of maternal death in Japan. Women who died during pregnancy or within a year after delivery were analyzed by the Maternal Death Exploratory Committee between 2012 and 2015 in Japan. Maternal deaths were analyzed to verify the requirement of autopsy in cases in which autopsy was performed and the need for autopsy in cases in which it was not performed. Among the 49 cases performed autopsy, the final diagnosis was compatible with the clinical course in 24 cases, while the autopsy diagnosis was incompatible with the clinical course in 13 cases. In two cases, the final diagnosis was based on the clinical course, but an autopsy could exclude other possible causes. In three cases, no exact cause of maternal death was identified after autopsy. On the other hand, in cases without an autopsy, the final diagnosis was made using ante-mortem operating findings and surgical specimens in twenty-one cases. Though, thirty-one cases were estimated diagnosis based on post-mortem imaging or ante-mortem examinations, the exact original cause of death was not determined in 25 cases, and the cause of death could not be identified in eight cases without autopsy. Because in most cases the autopsy provides an exact cause of death, the necessity of autopsies should be more widely accepted in Japan.

Pregnancy-associated Death - Clarifying the Cause of Death and Medico-legal Assessments in Accusations of Malpractice.

Science.gov (United States)

Dettmeyer, Reinhard; Lang, Juliane; Amberg, Rainer; Zedler, Barbara; Schulz, Ronald; Birngruber, Christoph

2018-02-01

Pregnancy-associated deaths are extremely rare in Germany. Most deaths are from natural causes, and a range of causes are possible. The deaths of 22 women who died of pregnancy-associated causes and who were autopsied in the Institute of Forensic Medicine of Justus-Liebig University Gießen between 1992 and 2016 were analyzed. The autopsy results and histological examinations for the majority of women who died of pregnancy-associated causes between 1992 and 2016 showed that they had died of natural causes, although complications of pregnancy were a leading cause of death. The death of a pregnant woman should not automatically raise the suspicion of malpractice, although the question does arise in cases of bleeding complications only detected at very late stages. Experts must prove that a real mistake was made during treatment and provide evidence of the causality between malpractice and patient death. Particularly when well-known complications of pregnancy were present, this is only the case if poor monitoring resulted in the complication being detected too late or if treatment was not in accordance with accepted standards of care. The majority of pregnancy-associated deaths are from natural causes and the death of a pregnant woman does not mean that medical malpractice was involved, although this accusation is often levelled in cases where rupture was not immediately diagnosed or in cases of fatal postpartum hemorrhage.

We examined the causes of death amongst full term stillbirths and early neonatal deaths. Our cohort includes women in the Region of Southern Denmark, who gave birth at full term to a stillborn infant or a neonate who died within the first 7 days from 2010 through 2014. Demographic, biometric and clinical variables were analyzed to assess the causes of death using two classification systems: causes of death and associated conditions (CODAC) and a Danish system based on initial causes of fetal death (INCODE). A total of 95 maternal-infant cases were included. Using the CODAC and INCODE classification systems, we found that the causes of death were unknown in 59/95 (62.1%). The second most common cause of death in CODAC was congenital anomalies in 10/95 (10.5%), similar to INCODE with fetal, genetic, structural and karyotypic anomalies in 11/95 (11.6%). The majority of the mothers were healthy, primiparous, non-smokers, aged 20-34 years and with a normal body mass index (BMI). Based on an unselected cohort from an entire region in Denmark, the cause of stillbirth and early neonatal deaths among full term infants remained unknown for the vast majority.

Dignity, death, and dilemmas: a study of Washington hospices and physician-assisted death.

Science.gov (United States)

Campbell, Courtney S; Black, Margaret A

2014-01-01

The legalization of physician-assisted death in states such as Washington and Oregon has presented defining ethical issues for hospice programs because up to 90% of terminally ill patients who use the state-regulated procedure to end their lives are enrolled in hospice care. The authors recently partnered with the Washington State Hospice and Palliative Care Organization to examine the policies developed by individual hospice programs on program and staff participation in the Washington Death with Dignity Act. This article sets a national and local context for the discussion of hospice involvement in physician-assisted death, summarizes the content of hospice policies in Washington State, and presents an analysis of these findings. The study reveals meaningful differences among hospice programs about the integrity and identity of hospice and hospice care, leading to different policies, values, understandings of the medical procedure, and caregiving practices. In particular, the authors found differences 1) in the language used by hospices to refer to the Washington statute that reflect differences among national organizations, 2) the values that hospice programs draw on to support their policies, 3) dilemmas created by requests by patients for hospice staff to be present at a patient's death, and 4) five primary levels of noninvolvement and participation by hospice programs in requests from patients for physician-assisted death. This analysis concludes with a framework of questions for developing a comprehensive hospice policy on involvement in physician-assisted death and to assist national, state, local, and personal reflection.

Apoptosis-like death in bacteria induced by HAMLET, a human milk lipid-protein complex.

Directory of Open Access Journals (Sweden)

Anders P Hakansson

Full Text Available BACKGROUND: Apoptosis is the primary means for eliminating unwanted cells in multicellular organisms in order to preserve tissue homeostasis and function. It is characterized by distinct changes in the morphology of the dying cell that are orchestrated by a series of discrete biochemical events. Although there is evidence of primitive forms of programmed cell death also in prokaryotes, no information is available to suggest that prokaryotic death displays mechanistic similarities to the highly regulated programmed death of eukaryotic cells. In this study we compared the characteristics of tumor and bacterial cell death induced by HAMLET, a human milk complex of alpha-lactalbumin and oleic acid. METHODOLOGY/PRINCIPAL FINDINGS: We show that HAMLET-treated bacteria undergo cell death with mechanistic and morphologic similarities to apoptotic death of tumor cells. In Jurkat cells and Streptococcus pneumoniae death was accompanied by apoptosis-like morphology such as cell shrinkage, DNA condensation, and DNA degradation into high molecular weight fragments of similar sizes, detected by field inverse gel electrophoresis. HAMLET was internalized into tumor cells and associated with mitochondria, causing a rapid depolarization of the mitochondrial membrane and bound to and induced depolarization of the pneumococcal membrane with similar kinetic and magnitude as in mitochondria. Membrane depolarization in both systems required calcium transport, and both tumor cells and bacteria were found to require serine protease activity (but not caspase activity to execute cell death. CONCLUSIONS/SIGNIFICANCE: Our results suggest that many of the morphological changes and biochemical responses associated with apoptosis are present in prokaryotes. Identifying the mechanisms of bacterial cell death has the potential to reveal novel targets for future antimicrobial therapy and to further our understanding of core activation mechanisms of cell death in eukaryote cells.

The in vivo colony method used to generate survival curves following exposure to ionizing irradiation allows to score large clones, representing surviving cells, and small colonies, representing late reproductive death. By subtraction, early-dying cells can be estimated. In the three human tumour cell lines examined, we have observed that early cell death is a major mode of action of irradiation. The contribution of early cell death to total mortality increases as the dose increases. Moreover, repair due to dose-splitting and delayed plating in densely-inhibited cells is not observed in early-dying cells. (authors)

Critics pay little attention to fear of death in Gulliver’s Travels. This paper aims to deal with the issue with Freud’s theory. According to Freud, fear of death results in death drive. In Gulliver’s Travels, the episodes of the Struldbruggs and the Houyhnhnms reveal fear of death. In the episode of Struldbruggs, fear of death is illustrated through fear of abandonment and fear of loss. Fear of abandonment and fear of loss cause the Struldbruggs to long for physical death to end emotional de...

Glutathione (L-γ-glutamyl-L-cysteinyl-glycine; GSH) in cancer cells is particularly relevant in the regulation of carcinogenic mechanisms; sensitivity against cytotoxic drugs, ionizing radiations, and some cytokines; DNA synthesis; and cell proliferation and death. The intracellular thiol redox state (controlled by GSH) is one of the endogenous effectors involved in regulating the mitochondrial permeability transition pore complex and, in consequence, thiol oxidation can be a causal factor in the mitochondrion-based mechanism that leads to cell death. Nevertheless GSH depletion is a common feature not only of apoptosis but also of other types of cell death. Indeed rates of GSH synthesis and fluxes regulate its levels in cellular compartments, and potentially influence switches among different mechanisms of death. How changes in gene expression, post-translational modifications of proteins, and signaling cascades are implicated will be discussed. Furthermore, this review will finally analyze whether GSH depletion may facilitate cancer cell death under in vivo conditions, and how this can be applied to cancer therapy.

New geophysical and fault kinematic studies indicate that late Cenozoic basin development in the Mormon Point area of Death Valley, California, was accommodated by fault rotations. Three of six fault segments recognized at Mormon Point are now inactive and have been rotated to low dips during extension. The remaining three segments are now active and moderately to steeply dipping. From the geophysical data, one active segment appears to offset the low-angle faults in the subsurface of Death Valley.

[What Lessons Should We Learn from the Death of Patients on Xeplion?].

Fujii, Yasuo

2015-01-01

From the launch of the long-acting injectable antipsychotic paliperidone palmitate (XEPLION) on November 19, 2013, 32 fatal cases had been reported up to May 18, 2014 (estimated number of users is approximately 11,000 patients) in the Early Post-marketing Phase Vigilance. The most common cause of death was sudden death (12 cases were sudden death defined by ICD-10 codes 96.0 and 96.1 and 4 cases suspected sudden death), followed by suicide (7 cases), and neuroleptic malignant syndrome (4 cases). Several deaths occurred involving patients with serious somatic disorder, such as a malignant tumor or pneumonia. The risk of all-cause mortality on XEPLION was not high in comparison with other investigations; the sudden death risk on XEPLION may be higher than on ZODIAC. According to many reports from foreign countries, mortality rates associated with schizophrenia are two to three times higher than those of the general population, corresponding to a 10-25-year reduction in life expectancy. Natural deaths account for about 60% of the excess mortality of schizophrenia patients, and such patients are more likely to die from ischemic heart disease. Since it has been suggested that more than half of sudden deaths in schizophrenic patients have a cardiac origin, sudden cardiac deaths are chiefly responsible for their reduced life expectancy. This sudden death-related problem of patients with schizophrenia has been forgotten or ignored in the psychiatric care of Japan. Taking advantage of this opportunity, we should tackle this problem seriously, and make an effort to reduce the mortality gap.

Radionuclide evaluation of brain death

Pjura, G.A.; Kim, E.E.

1987-01-01

The criteria employed for clinical determination of death have evolved in response to advances in life support and other medical technology. The technical feasibility of organ transplantation has amplified the need for a definition of brain death that can be applied in the shortest possible time in the presence of artificial maintenance of vegetative functions, including circulation. Radionuclide cerebral angiography is one of a group of diagnostic procedures that can be employed to confirm the clinical diagnosis of brain death through demonstration of absence of cerebral blood flow. The focus of this work is to assess its use as a confirmatory test for determination of brain death in the context of currently available alternative technologies

Transcatheter aortic valve replacement (TAVR) is an effective alternative to surgical aortic valve replacement in patients at high surgical risk. However, there is little published literature on the exact causes of death. The PubMed database was systematically searched for studies reporting causes of death within and after 30 days following TAVR. Twenty-eight studies out of 3934 results retrieved were identified. In the overall analysis, 46.4% and 51.6% of deaths were related to noncardiovascular causes within and after the first 30 days, respectively. Within 30 days of TAVR, infection/sepsis (18.5%), heart failure (14.7%), and multiorgan failure (13.2%) were the top 3 causes of death. Beyond 30 days, infection/sepsis (14.3%), heart failure (14.1%), and sudden death (10.8%) were the most common causes. All possible subgroup analyses were made. No significant differences were seen for proportions of cardiovascular deaths except the comparison between moderate (mean STS score 4 to 8) and high (mean STS score >8) -risk patients after 30 days post-TAVR (56.0% versus 33.5%, P=0.005). Cardiovascular and noncardiovascular causes of death are evenly balanced both in the perioperative period and at long-term follow-up after TAVR. Infection/sepsis and heart failure were the most frequent noncardiovascular and cardiovascular causes of death. This study highlights important areas of clinical focus that could further improve outcomes after TAVR. © 2015 The Authors.

A quiet ego quiets death anxiety: humility as an existential anxiety buffer.

Science.gov (United States)

Kesebir, Pelin

2014-04-01

Five studies tested the hypothesis that a quiet ego, as exemplified by humility, would buffer death anxiety. Humility is characterized by a willingness to accept the self and life without comforting illusions, and by low levels of self-focus. As a consequence, it was expected to render mortality thoughts less threatening and less likely to evoke potentially destructive behavior patterns. In line with this reasoning, Study 1 found that people high in humility do not engage in self-serving moral disengagement following mortality reminders, whereas people low in humility do. Study 2 showed that only people low in humility respond to death reminders with increased fear of death, and established that this effect was driven uniquely by humility and not by some other related personality trait. In Study 3, a low sense of psychological entitlement decreased cultural worldview defense in response to death thoughts, whereas a high sense of entitlement tended to increase it. Study 4 demonstrated that priming humility reduces self-reported death anxiety relative to both a baseline and a pride priming condition. Finally, in Study 5, experimentally induced feelings of humility prevented mortality reminders from leading to depleted self-control. As a whole, these findings obtained from relatively diverse Internet samples illustrate that the dark side of death anxiety is brought about by a noisy ego only and not by a quiet ego, revealing self-transcendence as a sturdier, healthier anxiety buffer than self-enhancement.

Rootwelt, V; Reksen, O; Farstad, W; Framstad, T

The fetal growth of the piglet is highly dependent on its placenta, and the newborn piglet birth weight is highly associated with postpartum death. However, there is little information available in the literature on the assessment of the placenta in relation to postpartum death in piglets. The aim of this study was to evaluate the impact of the placental area and placental weight, status of the umbilical cord, and piglet birth characteristics, such as blood parameters, vitality score, and birth weight on postpartum death. All live born piglets in litters from 26 Landrace-Yorkshire sows were monitored during farrowing and the status of each was recorded, including placental area and placental weight and blood variables obtained from the piglets and umbilical veins. Out of the 386 live-born piglets, 16.8% died before weaning at 5 wk. Among these, 78.5% died within the first 3 d of life. Mean blood concentration of lactate was increased in piglets that did not survive to weaning (P = 0.003). Concentrations of hemoglobin and hematocrit were decreased (P vitality score vs. piglets born with an intact umbilical cord (P = 0.021), and they had an increased probability of dying before weaning (P = 0.050). Mean birth weight, body mass index, placental area (P live litter size. Blood concentrations of IgG and albumin recorded at d 1 were decreased in piglets that died before weaning (P < 0.01), and blood concentration of albumin was positively associated with placental area (P < 0.001). We conclude that placental area and placental weight, status of the umbilical cord, birth weight, body mass index, blood concentrations of lactate, hemoglobin, and hematocrit recorded at birth, and blood concentrations of IgG and albumin recorded at d 1 were associated with postpartum death in this study. These results may indicate that there is an upper uterine limitation of litter size and that placental area and placental weight influence postpartum survival.

Death and dying is an ultimate process that every human being must experience. However, in these days we do not like to think or discuss about death and dying. Actually, hatred and denial is the usual feeling when we encounter death and dying. Dying is more than a biological occurrence. It is a human, social, and spiritual event, but the spiritual dimension of patients is too often neglected. Whether death is viewed as a "wall" or as a "door" can have significantly important consequences for how we live our lives. Near death experience is one of the excellent evidences to prove that there should be spiritual component being separated from the human physical body when we experience death. People have called it soul, spirit, or nonlocal consciousness. Caregivers need to recognize and acknowledge the spiritual component of patient care. Learning about death and dying helps us encounter death in ways that are meaningful for our own lives. Among the several learning tools, utilizing cinema with its audio and visual components can be one of the most powerful learning tools in death education.

Circulatory Arrest, Brain Arrest and Death Determination

Directory of Open Access Journals (Sweden)

Sam David Shemie

2018-03-01

Full Text Available Technological advances, particularly in the capacity to support, replace or transplant failing organs, continue to challenge and refine our understanding of human death. Given the ability to reanimate organs before and after death, both inside and outside of the body, through reinstitution of oxygenated circulation, concepts related to death of organs (e.g. cardiac death are no longer valid. This paper advances the rationale for a single conceptual determination of death related to permanent brain arrest, resulting from primary brain injury or secondary to circulatory arrest. The clinical characteristics of brain arrest are the permanent loss of capacity for consciousness and loss of all brainstem functions. In the setting of circulatory arrest, death occurs after the arrest of circulation to the brain rather than death of the heart. Correspondingly, any intervention that resumes oxygenated circulation to the brain after circulatory arrest would invalidate the determination of death.

Henrie, James; Patrick, Julie Hicks

Terror Management Theory (TMT) (Greenberg, Pyszczynski, & Solomon, 1986) suggests that culturally-provided worldviews (e.g., religion) may protect individuals from experiencing death anxiety, and several studies have supported this position. However, if one's worldview can offer protection, doubts concerning one's worldview could undermine this protection. The current study investigated whether age, gender, religiousness, and religious doubt were associated with death anxiety. Using data from 635 younger, middle-aged, and older adults, a structural equation model with age, gender, religiousness, and religious doubt predicting death anxiety was tested. The model had a good fit (chi2 (76) = 193.467, p religiousness was inversely associated with death anxiety, while religious doubt was positively associated with death anxiety.

Psychic trauma as cause of death.

Terranova, C; Snenghi, R; Thiene, G; Ferrara, S D

2011-01-01

of study Psychic trauma is described as the action of 'an emotionally overwhelming factor' capable of causing neurovegetative alterations leading to transitory or persisting bodily changes. The medico-legal concept of psychic trauma and its definition as a cause in penal cases is debated. The authors present three cases of death after psychic trauma, and discuss the definition of cause within the penal ambit of identified 'emotionally overwhelming factors'. The methodological approach to ascertainment and criterion-based assessment in each case involved the following phases: (1) examination of circumstantial evidence, clinical records and documentation; (2) autopsy; (3) ascertainment of cause of death; and (4) ascertainment of psychic trauma, and its coexisting relationship with the cause of death. The results and assessment of each of the three cases are discussed from the viewpoint of the causal connotation of psychic trauma. In the cases presented, psychic trauma caused death, as deduced from assessment of the type of externally caused emotional insult, the subjects' personal characteristics and the circumstances of the event causing death. In cases of death due to psychic trauma, careful methodological ascertainment is essential, with the double aim of defining 'emotionally overwhelming factors' as a significant cause of death from the penal point of view, and of identifying the responsibility of third parties involved in the death event and associated dynamics of homicide.

Increased anion channel activity is an unavoidable event in ozone-induced programmed cell death.

Directory of Open Access Journals (Sweden)

Takashi Kadono

Full Text Available BACKGROUND: Ozone is a major secondary air pollutant often reaching high concentrations in urban areas under strong daylight, high temperature and stagnant high-pressure systems. Ozone in the troposphere is a pollutant that is harmful to the plant. PRINCIPAL FINDINGS: By exposing cells to a strong pulse of ozonized air, an acute cell death was observed in suspension cells of Arabidopsis thaliana used as a model. We demonstrated that O(3 treatment induced the activation of a plasma membrane anion channel that is an early prerequisite of O(3-induced cell death in A. thaliana. Our data further suggest interplay of anion channel activation with well known plant responses to O(3, Ca(2+ influx and NADPH-oxidase generated reactive oxygen species (ROS in mediating the oxidative cell death. This interplay might be fuelled by several mechanisms in addition to the direct ROS generation by O(3; namely, H(2O(2 generation by salicylic and abscisic acids. Anion channel activation was also shown to promote the accumulation of transcripts encoding vacuolar processing enzymes, a family of proteases previously reported to contribute to the disruption of vacuole integrity observed during programmed cell death. SIGNIFICANCE: Collectively, our data indicate that anion efflux is an early key component of morphological and biochemical events leading to O(3-induced programmed cell death. Because ion channels and more specifically anion channels assume a crucial position in cells, an understanding about the underlying role(s for ion channels in the signalling pathway leading to programmed cell death is a subject that warrants future investigation.

Animal cell death comprising necrosis and apoptosis occurred in a well-regulated manner upon specific stimuli. The physiological meanings and detailed molecular mechanisms of cell death have been continuously investigated over several decades. Necrotic cell death has typical morphological changes, such as cell swelling and cell lysis followed by DNA degradation, whereas apoptosis shows blebbing formation and regular DNA fragmentation. Cell death is usually adopted to terminate cancer cells in vivo. The current strategies against tumour are based on the induction of cell death by adopting various methods, including radiotherapy and chemotherapeutics. Among these, radiotherapy is the most frequently used treatment method, but it still has obvious limitations. Recent studies have suggested that the use of nonthermal air plasma can be a prominent method for inducing cancer cell death. Plasma-irradiated cells showed the loss of genomic integrity, mitochondrial dysfunction, plasma membrane damage, etc. Tumour elimination with plasma irradiation is an emerging concept in cancer therapy and can be accelerated by targeting certain tumour-specific proteins with gold nanoparticles. Here, some recent developments are described so that the mechanisms related to plasma-mediated cell death and its perspectives in cancer treatment can be understood.

Consolidating birth-death and death-birth processes in structured populations.

Directory of Open Access Journals (Sweden)

Joshua Zukewich

Full Text Available Network models extend evolutionary game theory to settings with spatial or social structure and have provided key insights on the mechanisms underlying the evolution of cooperation. However, network models have also proven sensitive to seemingly small details of the model architecture. Here we investigate two popular biologically motivated models of evolution in finite populations: Death-Birth (DB and Birth-Death (BD processes. In both cases reproduction is proportional to fitness and death is random; the only difference is the order of the two events at each time step. Although superficially similar, under DB cooperation may be favoured in structured populations, while under BD it never is. This is especially troubling as natural populations do not follow a strict one birth then one death regimen (or vice versa; such constraints are introduced to make models more tractable. Whether structure can promote the evolution of cooperation should not hinge on a simplifying assumption. Here, we propose a mixed rule where in each time step DB is used with probability δ and BD is used with probability 1-δ. We derive the conditions for selection favouring cooperation under the mixed rule for all social dilemmas. We find that the only qualitatively different outcome occurs when using just BD (δ = 0. This case admits a natural interpretation in terms of kin competition counterbalancing the effect of kin selection. Finally we show that, for any mixed BD-DB update and under weak selection, cooperation is never inhibited by population structure for any social dilemma, including the Snowdrift Game.

The proactive search of deaths is a strategy for capturing events that were not informed to the Mortality Information System of Ministry of Health. Its importance to reduce underreporting of deaths and to evaluate the operation of the information system is widely known. To describe the methodology and main findings of the Proactive Search of Deaths, 2013, establishing the contribution of different information sources. The research was carried out in 79 Brazilian municipalities. We investigated several official and unofficial sources of information about deaths of municipality residents. Every information source investigated and all cases found in each source were typed in an on-line panel. The second stage of the research was the confirmation of cases to verify information of year and residence and to complete missing information. For all confirmed cases, we estimated the completeness of death registration and correction factors according to the adequacy level of mortality information. We found 2,265 deaths that were not informed to the Mortality Information System. From those, 49.3% were found in unofficial sources, cemeteries and funeral homes. In some rural municipalities, precarious burial conditions were found in cemeteries in the middle of the forest and no registration of the deceased. Correction factors were inversely associated to the adequacy level of mortality information. The findings confirm the association between level of information adequacy and completeness of death registration, and indicate that the application of the proactive search is an effective method to capture deaths not informed to the Ministry of Health.

"Death with dignity" in the Japanese context.

Science.gov (United States)

Shimoda, Motomu

2005-01-01

In Japan, "death with dignity" is a widely known term that is distinguished from "euthanasia." It is generally defined as "the act of letting a terminally ill or a patient in a persistent vegetative state die by withdrawing life-sustaining treatment on request in the form of a living will." Most Japanese people consider death with dignity a desirable way of terminating one's life and it is therefore acceptable as a "natural death" or "humane death." Originally, death with dignity was regarded as a passive intervention, but since the 1990s, its connotations have changed in western countries; people claim that voluntary active euthanasia and physician-assisted suicide should be legalized as death with dignity or the "right to die." In this paper, I examine the points and problems of this new type of death with dignity and propose an alternative version of death with dignity especially for the Japanese context, i.e. the end-of-life care process in support of terminal living with dignity.

Death with dignity from the Confucian perspective.

Science.gov (United States)

Li, Yaming; Li, Jianhui

2017-02-01

Death with dignity is a significant issue in modern bioethics. In modern healthcare, the wide use of new technologies at the end of life has caused heated debate on how to protect human dignity. The key point of contention lies in the different understandings of human dignity and the dignity of death. Human dignity has never been a clear concept in Western ethical explorations, and the dignity of death has given rise to more confusions. Although there is no such term as "dignity" in Confucian ethics, there are discussions of a number of ideas related to human dignity and the dignity of death. Therefore, Confucian bioethics can offer a new perspective for understanding the theoretical difficulties associated with the dignity of death and new methods for solving them. In this article, we attempt to reconstruct Confucian views on human dignity and the dignity of death and, based on those views, to analyze the following issues: the relationship between the dignity of death and biological life, the relationship between the dignity of death and suffering, the relationship between the dignity of death and the autonomy of human beings, and the relationship between the dignity of death and social justice. This article will also compare the Confucian views on these issues with the views of Western philosophers. Confucian ethics can offer distinct answers to the above issues and help resolve some confusions concerning concepts and theories in Western research on the dignity of death.

In the past, death was a family and community affair, but today it is institutional and entrusted to healthcare personnel. Thanks to a questionnaire on their feelings about prehospitalisation deaths, the experience and training needs for healthcare personnel at a mobile emergency and intensive care service were analysed. The majority of these professionals had been confronted with difficulties when faced with prehospitalisation deaths. There is little understanding of religious rites, even though this is an important point in dealing with the situation. There is a strong desire for training. The pedagogical support offered in response to the needs expressed was recognised as being useful and should be more widespread. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Death in life or life in death? Dementia's ontological challenge.

Science.gov (United States)

Macdonald, Gaynor

2018-01-01

Is it possible to end one's life well with dementia? The perception of dementia as death brought into life flows from ideas about humanness embedded in medicine's Cartesian paradigm. Dementia as incurable brain disease exacerbates negativity. But the real impact of dementia is that it changes social relations: to live well with dementia requires a relational not Cartesian understanding of life. A relational ontology prioritizes social health: to live is to be held in connection. Negativity produces the disconnection that is death, with or without disease. When people with dementia are held in connection, they live a better life.

The purpose of this article is to develop a conception of death with dignity and to examine whether it is vulnerable to the sort of criticisms that have been made of other conceptions. In this conception "death" is taken to apply to the process of dying; "dignity" is taken to be something that attaches to people because of their personal qualities. In particular, someone lives with dignity if they live well (in accordance with reason, as Aristotle would see it). It follows that health care pr...

Despite the public alarm following a series of high-profile school shootings that occurred in the United States during the late 1990s, little is known about the actual incidence and characteristics of school-associated violent deaths. To describe recent trends and features of school-associated violent deaths in the United States. Population-based surveillance study of data collected from media databases, state and local agencies, and police and school officials for July 1, 1994, through June 30, 1999. A case was defined as a homicide, suicide, legal intervention, or unintentional firearm-related death of a student or nonstudent in which the fatal injury occurred (1) on the campus of a public or private elementary or secondary school, (2) while the victim was on the way to or from such a school, or (3) while the victim was attending or traveling to or from an official school-sponsored event. National estimates of risk of school-associated violent death; national trends in school-associated violent deaths; common features of these events; and potential risk factors for perpetration and victimization. Between 1994 and 1999, 220 events resulting in 253 deaths were identified; 202 events involved 1 death and 18 involved multiple deaths (median, 2 deaths per multiple-victim event). Of the 220 events, 172 were homicides, 30 were suicides, 11 were homicide-suicides, 5 were legal intervention deaths, and 2 were unintentional firearm-related deaths. Students accounted for 172 (68.0%) of these deaths, resulting in an estimated average annual incidence of 0.068 per 100 000 students. Between 1992 and 1999, the rate of single-victim student homicides decreased significantly (P =.03); however, homicide rates for students killed in multiple-victim events increased (P =.047). Most events occurred around the start of the school day, the lunch period, or the end of the school day. For 120 (54.5%) of the incidents, respondents reported that a note, threat, or other action potentially

Nearly 90% of terminally ill patients who have used Oregon's distinctive death with dignity law to receive a medication to end their lives are enrolled in hospice care programs. In 2009-2010, we conducted a study of the policies developed by Oregon hospices to address patient inquiries and requests for death with dignity. The study examined the stated hospice values and positions and identified the boundaries to participation drawn by the hospice programs to protect personal and programmatic integrity. The boundaries were drawn around 6 key caregiving considerations: (1) language regarding physician-assisted death (PAD); (2) informed decision making by patients; (3) collaboration with physicians; (4) provision of lethal medication; (5) assistance in the patient's act of taking the medication; and (6) staff presence at the time of medication ingestion.

High mobility group box 1 (HMGB1), histone, and DNA are essential nuclear components involved in the regulation of chromosome structure and function. In addition to their nuclear function, these molecules act as damage-associated molecular patterns (DAMPs) alone or together when released extracellularly. The synergistic effect of these nuclear DNA-HMGB1-histone complexes as DAMP complexes (nDCs) on immune cells remains largely unexplored. Here, we demonstrate that nDCs limit survival of macrophages (e.g., RAW264.7 and peritoneal macrophages) but not cancer cells (e.g., HCT116, HepG2 and Hepa1-6). nDCs promote production of inflammatory tumor necrosis factor α (TNFα) release, triggering reactive oxygen species-dependent apoptosis and necrosis. Moreover, the receptor for advanced glycation end products (RAGE), but not toll-like receptor (TLR)-4 and TLR-2, was required for Akt-dependent TNFα release and subsequent cell death following treatment with nDCs. Genetic depletion of RAGE by RNAi, antioxidant N-Acetyl-L-cysteine, and TNFα neutralizing antibody significantly attenuated nDC-induced cell death. These findings provide evidence supporting novel signaling mechanisms linking nDCs and inflammation in macrophage cell death. - Highlights: • Nuclear DAMP complexes (nDCs) selectively induce cell death in macrophages, but not cancer cells. • TNFα-mediated oxidative stress is required for nDC-induced death. • RAGE-mediated Akt activation is required for nDC-induced TNFα release. • Blocking RAGE and TNFα inhibits nDC-induced macrophage cell death.

Cardiovascular diseases are major causes of mortality and morbidity. Cardiomyocyte apoptosis disrupts cardiac function and leads to cardiac decompensation and terminal heart failure. Delineating the regulatory signaling pathways that orchestrate cell survival in the heart has significant therapeutic implications. Cardiac tissue has limited capacity to regenerate and repair. Stem cell therapy is a successful approach for repairing and regenerating ischemic cardiac tissue; however, transplanted cells display very high death percentage, a problem that affects success of tissue regeneration. Stem cells display multipotency or pluripotency and undergo self-renewal, however these events are negatively influenced by upregulation of cell death machinery that induces the significant decrease in survival and differentiation signals upon cardiovascular injury. While efforts to identify cell types and molecular pathways that promote cardiac tissue regeneration have been productive, studies that focus on blocking the extensive cell death after transplantation are limited. The control of cell death includes multiple networks rather than one crucial pathway, which underlies the challenge of identifying the interaction between various cellular and biochemical components. This review is aimed at exploiting the molecular mechanisms by which stem cells resist death signals to develop into mature and healthy cardiac cells. Specifically, we focus on a number of factors that control death and survival of stem cells upon transplantation and ultimately affect cardiac regeneration. We also discuss potential survival enhancing strategies and how they could be meaningful in the design of targeted therapies that improve cardiac function.

Magnetic resonance imaging (MRI) was undertaken for two patients who suffered from severe cerebrovascular diseases and were clinically brain dead. The MRI system we used was Resona (Yokogawa Medical Systems, superconductive system 0.5 T) and the CT apparatus was Toshiba TCT-300. Initial CT and MRI were undertaken as soon as possible after admission, and repeated sequentially. After diagnosis of brain death, we performed angiography to determine cerebral circulatory arrest, and MRI obtained at the same time was compared with the angiogram and CT. Case 1 was a 77-year-old man who was admitted in an unconscious state. CT and MRI on the second day after hospitalization revealed cerebellar infarction. He was diagnosed as brain dead on day 4. Case 2 was a 35-year-old man. When he was transferred to our hospital, he was in cardiorespiratory arrested. Cardiac resuscitation was successful but no spontaneous respiration appeared. CT and MRI on admission revealed right intracerebral hemorrhage. Angiography revealed cessation of contrast medium in intracranial vessels in both of the patients. We found no 'flow signal void sign' in the bilateral internal carotid and basilar arteries on MRI images in both cases after brain death. MRI, showing us the anatomical changes of the brain, clearly revealed brain herniations, even though only nuclear findings of 'brain tamponade' were seen on CT. But in Case 1, we could not see the infarct lesions in the cerebellum on MR images obtained after brain death. This phenomenon was caused by the whole brain ischemia masking the initial ischemic lesions. We concluded that MRI was useful not only the anatomical display of lesions and brain herniation with high contrast resolution but for obtaining information on cerebral circulation of brain death.

2017-08-01

We investigate the geographic patterns of drug poisoning deaths involving heroin by county for the USA from 2000 to 2014. The county-level patterns of mortality are examined with respect to age-adjusted rates of death for different classes of urbanization and racial and ethnic groups, while rates based on raw counts of drug poisoning deaths involving heroin are estimated for different age groups and by gender. To account for possible underestimations in these rates due to small areas or small numbers, spatial empirical Baye's estimation techniques have been used to smooth the rates of death and alleviate underestimation when analyzing spatial patterns for these different groups. The geographic pattern of poisoning deaths involving heroin has shifted from the west coast of the USA in the year 2000 to New England, the Mid-Atlantic region, and the Great Lakes and central Ohio Valley by 2014. The evolution over space and time of clusters of drug poisoning deaths involving heroin is confirmed through the SaTScan analysis. For this period, White males were found to be the most impacted population group overall; however, Blacks and Hispanics are highly impacted in counties where significant populations of these two groups reside. Our results show that while 35-54-year-olds were the most highly impacted age group by county from 2000 to 2010, by 2014, the trend had changed with an increasing number of counties experiencing higher death rates for individuals 25-34 years. The percentage of counties across the USA classified as large metro with deaths involving heroin is estimated to have decreased from approximately 73% in 2010 to just fewer than 56% in 2014, with a shift to small metro and non-metro counties. Understanding the geographic variations in impact on different population groups in the USA has become particularly necessary in light of the extreme increase in the use and misuse of street drugs including heroin and the subsequent rise in opioid-related deaths in the

Death: the ultimate social construction of reality.

Science.gov (United States)

Brabant, Sarah

Using Berger and Luckmann's thesis (1966) on the social construction of reality as rationale, this research analyzes the death drawings of 946 university students enrolled in a Death and Dying course between 1985 and 2004 to investigate the basic constructs elicited by the word "death": dying, moment of death, after death, after life, and bereavement. Consistent with earlier research, gender, race, religion, and religiosity proved to be significant factors. As expected, personal experience with grief was strongly correlated with drawings focused on bereavement. In contrast to earlier studies, fear of death was not significantly related to a particular construct. Implications for research, education, and counseling are discussed.

Azam Malekifar

2016-01-01

Full Text Available Background: The increasing trend of traffic accidents is one of the most serious problems of public health. The aim of this paper was to investigate the fatal traffic accidents in Kermanshah province. Method: All research data required were obtained from Legal Medicine Organization and analyzed by Stata-11 software. Traffic statistics available on the Road Maintenance and Transportation Organization website were used to study the death rate per month and day according to traffic level on suburban highways. Results: The incidence rate of age-standardized deaths due to road traffic accidents was 26.1per 100,000 people, and the mean age of the dead was 39.98±21.60 years. The mortality rate was higher in men, those more than 40 years old, married, illiterate and self-employed. Considering the traffic rate on suburban roads, the highest death rate occurred in the warmest months of the year during the day. Furthermore, most deaths were due to collisions and the highest frequency of death was reported for the car occupants. In most cases, head injuries and head traumas were the final cause of death. A significant correlation was reported between the type of vehicle and the cause of death and how the accident occurred (P<0.05. Conclusion: The mortality rate due to traffic accidents in Kermanshah province is high. Surveillance over the suburban roads in hot seasons and male drivers is of particular importance.

Changes in the annual health examination records were investigated and classified by cause of death. In males with cancer, there was noted an increased incidence of abnormal hemoglobin amount, erythrocyte sedimentation rate, and traces of urinary proteins 1 year to 3 years before death. However, the incidence of urinary protein traces was low compared with that in other diseases. In males with cerebral vascular diseases, there was a high incidence of hypertension. Urinary protein traces appeared from 4 years to 5 years before death. In females with cardiovascular diseases including hypertensive diseases and valvular diseases, the incidence of urinary protein traces increased from 4 years to 5 years prior to their death. Erythrocyte sedimentation rate was generally high in these cases. In males with liver cirrhosis, urinary urobilinogen amount was generally more than that in other diseases. This tendency also appeared in females with liver cirrhosis 6 years before death. The incidence of abnormal hemoglobin amount and erythrocyte sedimentation rate was high in males with liver cirrhosis, and that of abnormal erythrocyte sedimentation rate was high in females with liver corrhosis.

Aradilla-Herrero, Amor; Tomás-Sabado, Joaquin; Gómez-Benito, Juana

The aims of this study were to analyze the relationships between death attitudes and perceived emotional intelligence in a sample of nursing students, and to determine whether there are differences between different academic years with regard to both emotional intelligence and death attitudes. The participants were 243 nursing students. They all responded voluntarily and anonymously to a questionnaire that assessed the following constructs: fear of death, death anxiety, death depression, death obsession, and emotional intelligence (attention, clarity, and mood repair). Students' scores on fear of death of others subscale (p nursing degree program and increased significantly on emotional clarity (p death of others. The importance of including emotional skills training and death-education programs as part of professional nursing curricula are discussed.

Validation and application of a death proxy in adult cancer patients.

Mealing, Nicole M; Dobbins, Timothy A; Pearson, Sallie-Anne

2012-07-01

PURPOSE: Fact of death is not always available on data sets used for pharmacoepidemiological research. Proxies may be an appropriate substitute in the absence of death data. The purposes of this study were to validate a proxy for death in adult cancer patients and to assess its performance when estimating survival in two cohorts of cancer patients. METHODS: We evaluated 30-, 60-, 90- and 180-day proxies overall and by cancer type using data from 12 394 Australian veterans with lung, colorectal, breast or prostate cancer. The proxy indicated death if the difference between the last dispensing record and the end of the observational period exceeded the proxy cutoff. We then compared actual survival to 90-day proxy estimates in a subset of 4090 veterans with 'full entitlements' for pharmaceutical items and in 3704 Australian women receiving trastuzumab for HER2+ metastatic breast cancer. RESULTS: The 90-day proxy was optimal with an overall sensitivity of 99.3% (95%CI: 98.4-99.7) and a specificity of 97.6% (95%CI: 91.8-99.4). These measures remained high when evaluated by cancer type and spread of disease. The application of the proxy using the most conservative date of death estimate (date of last dispensing) generally underestimated survival, with estimates up to 3 months shorter than survival based on fact of death. CONCLUSIONS: A 90-day death proxy is a robust substitute to identify death in a chronic population when fact of death is not available. The proxy is likely to be valid across a range of chronic diseases as it relies on the presence of 'regular' dispensing records for individual patients. Copyright © 2011 John Wiley & Sons, Ltd.

Cardiovascular conditions rank sixth in causes of death in 1- to 19-year-olds. Our study is the first analysis of the cardiovascular death data set from the National Center for the Review and Prevention of Child Deaths, which provides the only systematic collection of cardiovascular deaths in children. We developed an analytical data set from the National Center for the Review and Prevention of Child Deaths database for cardiovascular deaths in children 0 to 21 years old, reviewing 1,098 cases from 2005 to 2009 in 16 states who agreed to participate. Cardiovascular cases were aged 4.8 ± 6.6 years; 55.3%, ≤1 year; 24.6%, ≥10 years; male, 58%; white, 70.5%; black, 22.3%; Hispanic, 19.5%. Prior conditions were present in 48.5%: congenital heart disease, 23%; cardiomyopathies, 4.6%; arrhythmia, 1.7%; and congestive heart failure, 1.6%. Deaths occurred most frequently in urban settings, 49.2%; and in the hospital, 40.4%; home, 26.1%; or at school/work/sports, 4.8%. Emergency medical services were not evenly distributed with differences by age, race, ethnicity, and area. Autopsies (40.4%) occurred more often in those >10 years old (odds ratio [OR] 2.9), blacks (OR 1.6), or in those who died at school/work/sports (OR 3.9). The most common cardiovascular causes of death included congenital heart disease, 40.8%; arrhythmias, 27.1%; cardiomyopathy, 11.8%; myocarditis, 4.6%; congestive heart failure, 3.6%; and coronary artery anomalies, 2.2%. Our study identified differences in causes and frequencies of cardiovascular deaths by age, race, and ethnicity. Prevention of death may be impacted by knowledge of prior conditions, emergency plans, automated external defibrillator programs, bystander cardiopulmonary resuscitation education, and by a registry for all cardiovascular deaths in children.

Therapeutic approaches to preventing cell death in Huntington disease.

Science.gov (United States)

Kaplan, Anna; Stockwell, Brent R

2012-12-01

Neurodegenerative diseases affect the lives of millions of patients and their families. Due to the complexity of these diseases and our limited understanding of their pathogenesis, the design of therapeutic agents that can effectively treat these diseases has been challenging. Huntington disease (HD) is one of several neurological disorders with few therapeutic options. HD, like numerous other neurodegenerative diseases, involves extensive neuronal cell loss. One potential strategy to combat HD and other neurodegenerative disorders is to intervene in the execution of neuronal cell death. Inhibiting neuronal cell death pathways may slow the development of neurodegeneration. However, discovering small molecule inhibitors of neuronal cell death remains a significant challenge. Here, we review candidate therapeutic targets controlling cell death mechanisms that have been the focus of research in HD, as well as an emerging strategy that has been applied to developing small molecule inhibitors-fragment-based drug discovery (FBDD). FBDD has been successfully used in both industry and academia to identify selective and potent small molecule inhibitors, with a focus on challenging proteins that are not amenable to traditional high-throughput screening approaches. FBDD has been used to generate potent leads, pre-clinical candidates, and has led to the development of an FDA approved drug. This approach can be valuable for identifying modulators of cell-death-regulating proteins; such compounds may prove to be the key to halting the progression of HD and other neurodegenerative disorders.

The aim of this cross-sectional study was to examine the association of supernatural beliefs and sense of coherence with death anxiety and death depression in a Romanian sample of cancer patients. We found support for the terror management theory worldview defence hypothesis postulating the presence of a curvilinear relation between death anxiety and supernatural beliefs among cancer patients. Results conformed to an inverted U-shape quadratic regression, indicating that cancer patients who scored moderately on supernatural beliefs were afraid of death the most, while death anxiety was lowest for the extreme atheists and extreme believers in supernatural entities.

Disability Rating, Age at Death, and Cause of Death in U.S. Veterans with Service-Connected Conditions.

Maynard, Charles; Trivedi, Ranak; Nelson, Karin; Fihn, Stephan D

2018-03-26

The association between disability and cause of death in Veterans with service-connected disabilities has not been studied. The objective of this study was to compare age at death, military service and disability characteristics, including disability rating, and cause of death by year of birth. We also examined cause of death for specific service-connected conditions. This study used information from the VETSNET file, which is a snapshot of selected items from the Veterans Benefits Administration corporate database. We also used the National Death Index (NDI) for Veterans which is part of the VA Suicide Data Repository. In VETSNET, there were 758,324 Veterans who had a service-connected condition and died between the years 2004 and 2014. Using the scrambled social security number to link the two files resulted in 605,493 (80%) deceased Veterans. Age at death, sex, and underlying cause of death were obtained from the NDI for Veterans and military service characteristics and types of disability were acquired from VETSNET. We constructed age categories corresponding to period of service; birth years 1938 and earlier corresponded to Korea and World War II ("oldest"), birth years 1939-1957 to the Vietnam era ("middle"), and birth years 1958 and later to post Vietnam, Gulf War, and the more recent conflicts in Iraq and Afghanistan ("youngest"). Sixty-two percent were in the oldest age category, 34% in the middle group, and 4% in the youngest one. The overall age at death was 75 ± 13 yr. Only 1.6% of decedents were women; among women 25% were in the youngest age group, while among men only 4% were in the youngest group. Most decedents were enlisted personnel, and 60% served in the U.S. Army. Nearly 61% had a disability rating of >50% and for the middle age group 54% had a disability rating of 100%. The most common service-connected conditions were tinnitus, hearing loss, and post-traumatic stress disorder (PTSD). In the oldest group, nearly half of deaths were due to

Scale of Death Anxiety (SDA: Development and Validation

Wei Cai

2017-05-01

Full Text Available This study developed and validated a new measure to assess the death anxiety (i.e., Scale of Death Anxiety, SDA on an individual’s somatic, cognitive, emotional, and behavioral reactions from a symptomatic perspective in Chinese youth samples. Following a systematic process, a four-factor structure of the SDA was identified through principle components analysis and confirmatory factor analysis that revealed four aspects of death anxiety: Dysphoria, Death Intrusion, Fear of Death, and Avoidance of Death. The results of this study indicate that the SDA has a clear factor structure and good psychometric properties. The SDA supports death anxiety as a multidimensional construct, and the foundational role of fear of death in the generation of death anxiety. This scale is valuable and beneficial to research on death anxiety. This study makes a significant contribution to the literature because the SDA is the first assessment of death anxiety to include the constructs of dysphoria and somatic symptoms. And the potential clinical practice of the SDA was discussed.

Lavack, A M

1999-01-01

This content analysis examines a sample of 203 alcohol-related North American TV commercials dealing with alcohol moderation and driving under the influence (DUI), in order to determine whether the type of ad sponsor has an impact on the message content. Corporate sponsors, such as breweries and distillers, are compared to nonprofit sponsors such as governments and nonprofit organizations. Findings show that ads from corporate sponsors are less likely to make mention of threats or negative consequences, and are also less likely to use fear arousal. However, DUI/alcohol moderation ads from corporate sponsors and nonprofit sponsors do not differ in the degree to which they use humor or positive approaches.

Prosperity as a cause of death.

Science.gov (United States)

Eyer, J

1977-01-01

The general death rate rises during business booms and falls during depressions. The causes of death involved in this variation range from infectious diseases through accidents to heart disease, cancer, and cirrhosis of the liver, and include the great majority of all causes of death. Less than 2 percent of the death rate-that for suicide and homicide-varies directly with unemployment. In the older historical data, deterioration of housing and rise of alcohol consumption on the boom may account for part of this variation. In twentieth-century cycles, the role of social stress is probably predominant. Overwork and fragmentation of community through migration are two important sources of stress which rise with the boom, and they are demonstrably related to the causes of death which show this variation.

Currently, little is known about rates of death by cause and country among US travellers. Understanding the risk by cause and country is imperative to risk communication and the development of risk reduction strategies. Publicly available data on non-natural deaths of US citizens abroad were gathered from January 2003 to December 2009 from the US Department of State's Department Bureau of Consular Affairs. Traveller information was gathered from the US Department of Commerce Office of Travel and Tourism for the same time period. Rates of death were calculated by dividing the number of non-natural deaths of US citizens abroad by the number of US outbound visits for each country. A total of 5417 non-natural death events were retrieved between 2003 and 2009 from the US State Department. Intentionally caused death rates ranged from 21.44 per 1 000 000 visits in the Philippines to 0 per 1 000 000 visits in several countries; the majority of countries had fewer than five intentionally caused deaths per 1 000 000 visits. Rates of road traffic crashes were higher than rates of intentionally caused deaths in almost every instance. Thailand had the highest rate of deaths due to road traffic crashes (16.49 per 1 000 000), followed by Vietnam, Morocco and South Africa (15.12 per 1 000 000, 11.96 per 1 000 000 and 10.90 per 1 000 000, respectively). Motorcycle deaths account for most of the heightened risk observed in Thailand and Vietnam. The leading cause of non-natural deaths in US travellers abroad was road crashes, which exceeds intentional injury as the leading cause of non-natural deaths in almost every country where US citizens travel. Southeast Asia had the highest unintentional injury death rates for US citizens abroad due to the high rates of deaths from motorcycle crashes. Published by the BMJ Publishing Group Limited.

Insights on dying, dementia and death certificates.

2018-01-01

For our master thesis in medicine, we aimed to determine how many deaths were caused by and with dementia in 2014 and we compared our results with figures from abroad. The mortality rates of 2014 in Flanders were used to determine the amount of deaths related to dementia. These figures are collected by Vlaams Agentschap Zorg & Gezondheid (VAZG) and coded per ICD-10 classification. Of all deaths in Flanders in 2014, 6.60% were caused by dementia and 4.29% were caused by another condition, while also suffering from dementia. Data from abroad are ambiguous. While working on our thesis about "death & dementia", we questioned the reliability of mortality statistics. Possible explanations could be; the complexity of completing death certificates correctly and the challenges involved in properly constructing a chain of causes of death. The accuracy of mortality data can be improved by training and redrafting death certificates.

As every other aspect of life is to be found online, so are death and the surrounding issues. The research into the area is not far behind, and using the approach of a timeline...... with different stakeholders, this research review offers a systematic way of keeping track. The rather simple timeline relates to the death of a person, there is before, just around, and after death, appropriately named in a dead language: Ante Mortem, Peri Mortem, and Post Mortem. This review deals exclusively...... with the digital context of the physical death of existing human beings, as opposed to, e.g., in-game death experience or memorials for fictional characters. These are no doubt interesting issues that deserve their own review, although we might need to put citation marks around "death"....

Caffeine is the most widely consumed psychoactive compound worldwide. It is mostly found in coffee, tea, energizing drinks and in some drugs. However, it has become really easy to obtain pure caffeine (powder or tablets) on the Internet markets. Mechanisms of action are dose-dependent. Serious toxicities such as seizure and cardiac arrhythmias, seen with caffeine plasma concentrations of 15 mg/L or higher, have caused poisoning or, rarely, death; otherwise concentrations of 3⁻6 mg/kg are considered safe. Caffeine concentrations of 80⁻100 mg/L are considered lethal. The aim of this systematic review, performed following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement for the identification and selection of studies, is to review fatal cases in which caffeine has been recognized as the only cause of death in order to identify potential categories at risk. A total of 92 cases have been identified. These events happened more frequently in infants, psychiatric patients, and athletes. Although caffeine intoxication is relatively uncommon, raising awareness about its lethal consequences could be useful for both clinicians and pathologists to identify possible unrecognized cases and prevent related severe health conditions and deaths.

This article explains the problems with Alan Shewmon’s critique of brain death as a valid sign of human death, beginning with a critical examination of his analogy between brain death and severe spinal cord injury. The article then goes on to assess his broader argument against the necessity of the brain for adult human organismal integration, arguing that he fails to translate correctly from biological to metaphysical claims. Finally, on the basis of a deeper metaphysical analysis, I offer a revised rationale for the validity of the neurological criterion of human death. PMID:27095749

Mortality statistics from the Centers for Disease Control and Prevention (CDC) is used for planning healthcare policy and allocating resources. CDC uses this data to compile its annual leading-causes-of-death ranking based on a selected list of 113 causes. SLE is not included on this list. Since the cause-of-death ranking is a useful tool for assessing the relative burden of cause-specific mortality, we ranked SLE deaths among CDC's leading causes-of-death to see whether SLE is a significant cause of death among women. Death counts were obtained from the CDC's Wide-ranging Online Data for Epidemiologic Research database in U.S. female population, and then grouped by age and race/ethnicity. Data on the leading causes-of-death were obtained from the Web-based Injury Statistics Query and Reporting System database. During 2000 to 2015, there were 28,411 female deaths with SLE recorded as the underlying or contributing causes of death. SLE ranked among the top 20 leading-causes-of-death in females between 5 and 64 years of age. SLE ranked 10 th in the 15-24 years, 14 th in the 25-34 and the 35-44 years, and 15 th in the 10-14 years age groups. Among black and Hispanic females, SLE ranked 5 th in the 15-24 years, 6 th in the 25-34 years, and 8 th -9 th in the 35-44 years age groups, after excluding the three common external injury causes of death from analysis. SLE is among the leading-causes-of-death in young women, underscoring its impact as an important public health issue. This article is protected by copyright. All rights reserved.

Assessment of the joint and independent relationships of gestational weight gain and prepregnancy body mass index (BMI) on risk of infant mortality was performed. This study used Pennsylvania linked birth-infant death records (2003-2011) from infants without anomalies born to mothers with prepregnancy BMI categorized as underweight (n = 58,973), normal weight (n = 610,118), overweight (n = 296,630), grade 1 obesity (n = 147,608), grade 2 obesity (n = 71,740), and grade 3 obesity (n = 47,277). Multivariable logistic regression models stratified by BMI category were used to estimate dose-response associations between z scores of gestational weight gain and infant death after confounder adjustment. Infant mortality risk was lowest among normal-weight women and increased with rising BMI category. For all BMI groups except for grade 3 obesity, there were U-shaped associations between gestational weight gain and risk of infant death. Weight loss and very low weight gain among women with grades 1 and 2 obesity were associated with high risks of infant mortality. However, even when gestational weight gain in women with obesity was optimized, the predicted risk of infant death remained higher than that of normal-weight women. Interventions aimed at substantially reducing preconception weight among women with obesity and avoiding very low or very high gestational weight gain may reduce risk of infant death. © 2015 The Obesity Society.

The aims of this study were to examine the relationship between negative attitudes towards expressing emotion following patient death and burnout in oncologists and to explore oncologists' preferences for institutional interventions to deal with patient death. The participants included a convenience sample of 177 oncologists from Israel and Canada. Oncologists completed a questionnaire package that included a sociodemographic survey, a burnout measure, a survey assessing negative attitudes towards expressing emotion, and a survey assessing desired interventions to cope with patient death. To examine the association between burnout and negative attitudes while controlling for the effect of sociodemographic variables, a hierarchical linear regression was computed. Higher burnout scores were related to higher negative attitudes towards perceived expressed emotion (partial r = .25, p training) helpful in coping with patient death. Our findings suggest that high burnout scores are associated with negative attitudes towards expressing emotion and that there is a wide variation in oncologist preferences in coping with patient death. Institutions should promote interventions that are varied and that focus on the needs of oncologists in order to reduce burnout. Interventions that legitimize expression of emotion about patient death may be useful. Another way to reduce stigma would be to require oncologists to "opt out" rather than "opt in" to accessing a selection of social and/or individual interventions.

Sudden cardiac death in athletes

Full Text Available ABSTRACT The most accepted definition of sudden cardiac death nowadays is an unexplained death occurred suddenly within one hour of symptom onset. If it was not witnessed, individuals need to had been observed for at least 24 hours before the event and should be discarded the possibility of non cardiac causes of sudden death, pulmonary embolism or extensive malignancy. The term athlete refers to individuals of any age who participate in collective or individual regular physical activity, as well as physical training program for regular competitions. The sudden death of a young athlete, whether amateur or professional, especially during competitions, is always dramatic, with strong negative social impact and in the media. The fact that sports are recommended as a formula for longevity and quality of life makes these events a cause for concern in sports and society in general.

First, to evaluate the influence of comorbid diseases and concomitant injuries on the risk of in-hospital death after traumatic spinal cord injury (TSCI). Second, to identify the risk characteristics of TSCI patients with likelihood of death. Population-based retrospective cohort study. Sixty-two acute care hospitals in South Carolina, USA. Records of 3389 TSCI patients hospitalized with acute TSCI were evaluated. Days elapsing from the date of injury to date of death established the survival time (T). Cox regression examined risk of in-hospital death as a function of counts of comorbid conditions and injuries along with their joint effects controlling for other covariates. Counts of comorbid conditions and injuries showed dose-dependent risk of death while in-hospital independent of demographical and clinical covariates. Hazard ratios (HR) for counts 3+, 2 and 1 comorbid conditions were 2.19 (P<0.001), 1.73 (P=0.005) and 1.20 (P=0.322), respectively. For counts of 4+, 3 and 2 other injuries were 1.85 (P<0.001), 1.81 (P<0.001) and 1.46 (P=0.022), respectively. The joint effect of the two was transadditive with statistically significant HR ranging from 1.72-3.14. Counts of comorbid conditions and injured body regions strongly indicate risk of in-hospital death after TSCI and their joint effects elicited dose-dependent gradient independent of demographical and clinical covariates. Assessing risk of in-hospital death based on joint use of counts of comorbid diseases and injuries is highly informative to target TSCI patients at high risk of dying.

The unfolding counter-transition in rural South Africa: mortality and cause of death, 1994-2009.

Full Text Available The HIV pandemic has led to dramatic increases and inequalities in adult mortality, and the diffusion of antiretroviral treatment, together with demographic and socioeconomic shifts in sub-Saharan Africa, has further changed mortality patterns. We describe all-cause and cause-specific mortality patterns in rural South Africa, analyzing data from the Agincourt health and socio-demographic surveillance system from 1994 to 2009 for those aged 5 years and older. Mortality increased during that period, particularly after 2002 for ages 30-69. HIV/AIDS and TB deaths increased and recently plateaued at high levels in people under age 60. Noncommunicable disease deaths increased among those under 60, and recently also increased among those over 60. There was an inverse gradient between mortality and household SES, particularly for deaths due to HIV/AIDS and TB and noncommunicable diseases. A smaller and less consistent gradient emerged for deaths due to other communicable diseases. Deaths due to injuries remained an important mortality risk for males but did not vary by SES. Rural South Africa continues to have a high burden of HIV/AIDS and TB mortality while deaths from noncommunicable diseases have increased, and both of these cause-categories show social inequalities in mortality.

A carefully classified dataset of perinatal mortality will retain the most significant information on the causes of death. Such information is needed for health care policy development, surveillance and international comparisons, clinical services and research. For comparability purposes, we propose a classification system that could serve all these needs, and be applicable in both developing and developed countries. It is developed to adhere to basic concepts of underlying cause in the International Classification of Diseases (ICD), although gaps in ICD prevent classification of perinatal deaths solely on existing ICD codes.We tested the Causes of Death and Associated Conditions (Codac) classification for perinatal deaths in seven populations, including two developing country settings. We identified areas of potential improvements in the ability to retain existing information, ease of use and inter-rater agreement. After revisions to address these issues we propose Version II of Codac with detailed coding instructions.The ten main categories of Codac consist of three key contributors to global perinatal mortality (intrapartum events, infections and congenital anomalies), two crucial aspects of perinatal mortality (unknown causes of death and termination of pregnancy), a clear distinction of conditions relevant only to the neonatal period and the remaining conditions are arranged in the four anatomical compartments (fetal, cord, placental and maternal).For more detail there are 94 subcategories, further specified in 577 categories in the full version. Codac is designed to accommodate both the main cause of death as well as two associated conditions. We suggest reporting not only the main cause of death, but also the associated relevant conditions so that scenarios of combined conditions and events are captured.The appropriately applied Codac system promises to better manage information on causes of perinatal deaths, the conditions associated with them, and the most

Karoshi--death from overwork: occupational health consequences of Japanese production management.

Nishiyama, K; Johnson, J V

1997-01-01

There is considerable international interest in Japanese production management (JPM), known in the West as "lean production." Advocates of this new form of management argue that it improves both economic productivity and health. In Japan, however, the relationship between JPM and sudden death due to cardiovascular and cerebrovascular disease has been an important topic of debate since the 1970s. Japanese have named these types of deaths karoshi, which means "death from overwork." In North America and Western Europe a number of studies have demonstrated a significant relationship between high job strain (high production demands and low levels of control and social support) and cardiovascular disease. This article reviews the elements of JPM and examines their potential health consequences. The authors present an overview of karoshi, discuss its possible connections to specific ideological and organizational characteristics of JPM, and suggest the job strain mechanism as a possible pathway between karoshi and JPM. They conclude by discussing the need for comparative research that examines the health effects of work organization and management methods cross-culturally.

The social construction of drug-related death.

Science.gov (United States)

Cruts

2000-12-01

This article invites you to a social constructionist view on the issue of drug-related death. Social constructionism is often misunderstood for denying plain facts. It sure is a fact that there are deadly doses of legal and illegal substances. In this sense it is a truism that drugs kill people. Nonetheless, it is argued that reducing the causes of death to a certain drug as the essential underlying cause of death is a social construction. A case is discussed to demonstrate that a drug-related death can just as well be seen as a free-market death. Free markets kill people at least as much as drugs do. It is argued that drug-related death is a social construction, because attributing a death to a drug is based on unfalsifiable counterfactual thinking. Counterfactual thoughts about what the world would look like if there were no drugs, are seen as expressing one's view of life.

Are adolescents with high socioeconomic status more likely to engage in alcohol and illicit drug use in early adulthood?

Full Text Available Abstract Background Previous literature has shown a divergence by age in the relationship between socioeconomic status (SES and substance use: adolescents with low SES are more likely to engage in substance use, as are adults with high SES. However, there is growing evidence that adolescents with high SES are also at high risk for substance abuse. The objective of this study is to examine this relationship longitudinally, that is, whether wealthier adolescents are more likely than those with lower SES to engage in substance use in early adulthood. Methods The study analyzed data from the National Longitudinal Survey of Adolescent Health (AddHealth, a longitudinal, nationally-representative survey of secondary school students in the United States. Logistic regression models were analyzed examining the relationship between adolescent SES (measured by parental education and income and substance use in adulthood, controlling for substance use in adolescence and other covariates. Results Higher parental education is associated with higher rates of binge drinking, marijuana and cocaine use in early adulthood. Higher parental income is associated with higher rates of binge drinking and marijuana use. No statistically significant results are found for crystal methamphetamine or other drug use. Results are not sensitive to the inclusion of college attendance by young adulthood as a sensitivity analysis. However, when stratifying by race, results are consistent for white non-Hispanics, but no statistically significant results are found for non-whites. This may be a reflection of the smaller sample size of non-whites, but may also reflect that these trends are driven primarily by white non-Hispanics. Conclusions Previous research shows numerous problems associated with substance use in young adults, including problems in school, decreased employment, increases in convictions of driving under the influence (DUI and accidental deaths. Much of the previous
