    The World is undergoing rapid urbanization, with 70% of the World population expected to live in urban areas by 2050. Nevertheless, nationally representative analysis of the health differences in the leading causes of avoidable mortality disaggregated by urbanization level is lacking. We undertake a study of temporal trends in mortality rates for deaths considered avoidable by the Concerted Action of the European Community on Avoidable Mortality for four different levels of urbanization in Taiwan between 1971 and 2008. We find that for virtually all causes of death, age-standardized mortality rates (ASMRs) were lower in more urbanized than less urbanized areas, either throughout the study period, or by the end of the period despite higher rates in urbanized areas initially. Only breast cancer had consistently higher AMSRs in more urbanized areas throughout the 38-year period. Further, only breast cancer, lung cancer, and ischemic heart disease witnessed an increase in ASMRs in one or more urbanization categories. More urbanized areas in Taiwan appear to enjoy better indicators of health outcomes in terms of mortality rates than less urbanized areas. Access to and the availability of rich healthcare resources in urban areas may have contributed to this positive result.

    Cases of primordial cysts derived from the records of all the hospital pathology departments and private pathology practices on the Witwatersrand, were recorded for the 10-year period 1965-74. The population at risk (1970 census) was 974,390 Whites and 1,567,280 Blacks. Age-specific morbidity rates for each sex and race were calculated, as well as age-standardized incidence rates standardized against African, World and European standard populations. The age-standardized incidence rates for primordial cysts, standardized against a World standard population, per million per year are 0.61, 0, 4.86 and 3.50 for Black males and females and White males and females, respectively. In the population at risk, primordial cysts are much more common in Whites than in Blacks, the incidence being eight times higher in White males than in Black males. The present study confirms that there is a bimodal age distribution but with a higher incidence of the cyst in the age group 50-64 years than previously suspected. This may be either because a substantial number of cases remain undiagnosed for many years or because there are two groups of primordial cyst: one which is triggered in young patients and the other in older patients.

  4. Age-standardized Incidence Rates for Leukemia Associated with Consanguineous Marriages in 68 Countries, an Ecological Study.

    Consanguineous marriage that defines as a union between biologically related persons has a variety of known deleterious correlations with factors that affect public health within human populations. To investigate the association between the mean of inbreeding coefficient (α) and incidence of leukemia, the present ecological study on 68 countries was carried out. Statistical analysis showed that the age-standardized incidence rate of leukemia positively correlated with log10GNI per capita (r=0.699, df=66, P<0.001) and negatively correlated with log10α (r=-0.609, df=66, P<0.001). Controlling log10GNI per capita, a significant negative correlation between log10α and the age-standardized incidence rate of leukemia was observed (r=-0.392, df=65, P=0.001). The countries were stratified according to their annual GNI per capita, low and high-income countries with GNI per capita less than and more than 10,000$, respectively. Statistical analysis showed that in high-income countries, after controlling for log10GNI per capita, the correlation between the age-standardized incidence rate of leukemia and log10α was still significant (r=-0.600, df=36, P<0.001). It should be noted that there was no significant association between the age-standardized mortality rate due to leukemia and log10α (P>0.05). The present finding indicates that the rate of leukemia, age-standardized for incidence, is lower in countries with a high prevalence of consanguineous marriages.

    Although a great deal is known about the incidence of cancer, including oral cancer, no such study has been done on odontogenic tumors and jaw cysts. There are therefore no standardized data which would allow for comparative incidences in different countries and between different groups. In the present study, cases of ameloblastomas and dentigerous cysts derived from the records of all the hospital pathology departments and private pathology practices on the Witwatersrand, were recorded for the 10-year period 1965--1974. The population at risk (1970 census) was 974,390 Whites and 1,567,280 Blacks. The annual incidence rates, standardized against the standard world population, for ameloblastomas per million population are 1.96, 1.20, 0.18 and 0.44 for Black males, females and White males, females, respectively. The equivalent four figures for dentigerous cysts are 1.18, 1.22, 9.92 and 7.26. These figures show that ameloblastoma is very much more common in Blacks than Whites in the population at risk. Conversely, dentigerous cysts are much more common in Whites. This makes it unlikely that dentigerous cysts predispose to ameloblastoma formation. These epidemiologic observations give rise to speculation as to whether some component of the South African Black diet or other environmental substance might possibly be an etiologic factor in ameloblastoma.

    Osteosarcoma is a common primary malignant bone tumor in children and adolescents. Recent worldwide average incidences of osteosarcoma in people aged 0 to 24 years were 4.3 and 3.4 per million, respectively, with a ratio of 1.4:1. However, data on the incidence of osteosarcoma in Thailand are limited. This study analyzed the incidence of osteosarcoma in the upper northern region of Thailand, with a population of 5.85 million people (8.9% of the total Thai population), using data for the years 1998 to 2012, obtained from the Chiang Mai Cancer Registry (CMCR) at Chiang Mai University Hospital and the Lampang Cancer Registry (LCR) at the Lampang Cancer Hospital, a total of 144 cases. The overall annual incidence of osteosarcoma was 1.67 per million with a male:female ratio of 1.36:1. Incidences by age group (male and female) at 0 to 24, 25 to 59 and over 60 years were 3.5 (3.9 and 3.0), 0.8 (0.9 and 0.6), and 0.7 (0.8 and 0.5), respectively. The peak incidence occurred at 15 to 19 years for males and at 10 to 14 years for females. The median survival time was 18 months with a 5year survival rate of 43%. Neither the age group nor the 5year interval period of treatment was significantly correlated with survival during the 15year period studied. PMID:27509991

    OBJECTIVE: To account for variations in death rates in population subgroups of the USA. METHODS: Factors associated with age-adjusted death rates in 366 metropolitan and non- metropolitan areas of the United States were examined for 1990-92. The rates ranged from 690 to 1108 per 100 000 population (mean = 885 +/- 78 per 100 000). FINDINGS: Least squares regression analysis explained 71% of this variance. Factors with the strongest independent positive association were ethnicity (African-American), less than a high school education, high Medicare expenditures, and location in western or southern regions. Factors with the strongest independent negative associations were employment in agriculture and forestry, ethnicity (Hispanic) and per capita income. CONCLUSION: Additional research at the individual level is needed to determine if these associations are causal, since some of the factors with the strongest associations, such as education, have long latency periods.

    It is conceived that specific combinations of periodontal bacteria are associated with risk for the various forms of periodontitis. We hypothesized that such specificity is also related to human cause-specific death rates. We tested this hypothesis in a representative sample of the US population followed for a mean duration of 11 years and found that two specific patterns of 21 serum antibodies against periodontal bacteria were significantly associated with increased all-cause and/or diabetes-related mortalities. These data suggested that specific combinations of periodontal bacteria, even without inducing clinically significant periodontitis, may have a significant impact on human cause-specific death rates. Our findings implied that increased disease and mortality risk could be transmittable via the transfer of oral microbiota, and that developing personalized strategies and maintaining healthy oral microbiota beyond protection against periodontitis would be important to manage the risk.

    The United States system of immigrant detention centers has been the subject of considerable scrutiny with respect to health care of detainees. We sought to characterize the rates and types of deaths that have occurred within this system between the years 2003–2015. We analyzed a file of detainee deaths released by the U.S. Department of Homeland Security as part of a freedom of information request. Between 2003 and 2015, 150 deaths were recorded. During this time period, the annual rate of death among detainees dropped dramatically, whether measured by annual admissions or by person years of exposure. The most common causes of death were cardiovascular, cancer and suicide. More research is needed to adequately account for the contributors to these declining rates of death in immigration detention settings. PMID:26569284

    Objective This study investigated the preventable death rate in Daegu, South Korea, and assessed affecting factors and preventable factors in order to improve the treatment of regional trauma patients. Methods All traumatic deaths between January 2012 and December 2012 in 5 hospitals in Daegu were analyzed by panel review, which were classified into preventable and non-preventable deaths. We determined the factors affecting trauma deaths and the preventable factors during trauma care. Results There were overall 358 traumatic deaths during the study period. Two hundred thirty four patients were selected for the final analysis after excluding cases of death on arrival, delayed death, and unknown causes. The number of preventable death was 59 (25.2%), which was significantly associated with mode of arrival, presence of head injury, date, and time of injury. A multivariate analysis revealed that preventable death was more likely when patients were secondly transferred from another hospital, visited hospital during non-office hour, and did not have head injuries. The panel discovered 145 preventable factors, which showed that majority of factors occurred in emergency departments (49.0%), and were related with system process (76.6%). Conclusion The preventable trauma death rate in Daegu was high, and mostly process-related. PMID:27752603

    Proponents of global warming predict adverse events due to a slight warming of the planet in the last 100 years. This ecological study tests one of the possible arguments that might support the global warming theory – that it may increase cancer death rates. Thus, average daily air temperature is compared to cancer death rates at the county level in a U.S. state, while controlling for variables of smoking, race, and land elevation. The study revealed that lower cancer death rates were associated with warmer temperatures. Further study is indicated to verify these findings. PMID:26674418

    In US states with small subpopulations, the observed mortality rates are often zero, particularly among young ages. Because in life tables, death rates are reported mostly on a log scale, zero mortality rates are problematic. To overcome the observed zero death rates problem, appropriate probability models are used. Using these models, observed zero mortality rates are replaced by the corresponding expected values. This enables logarithmic transformations and, in some cases, the fitting of the eight-parameter Heligman-Pollard model to produce mortality estimates for ages 0-130 years, a procedure illustrated in terms of mortality data from several states.

    Background Data from several previous studies examining heart-rate and cardiovascular risk have hinted at a possible relationship between heart-rate and non-cardiac mortality. We thus systematically examined the predictive value of heart-rate variables on the subsequent risk of death from cancer. Methods In the Paris Prospective Study I, 6101 asymptomatic French working men aged 42 to 53 years, free of clinically detectable cardiovascular disease and cancer, underwent a standardized graded exercise test between 1967 and 1972. Resting heart-rate, heart-rate increase during exercise, and decrease during recovery were measured. Change in resting heart-rate over 5 years was also available in 5139 men. Mortality including 758 cancer deaths was assessed over the 25 years of follow-up. Findings There were strong, graded and significant relationships between all heart-rate parameters and subsequent cancer deaths. After adjustment for age and tobacco consumption and, compared with the lowest quartile, those with the highest quartile for resting heart-rate had a relative risk of 2.4 for cancer deaths (95% confidence interval: 1.9–2.9, p<0.0001) This was similar after adjustment for traditional cardiovascular risk factors and was observed for the commonest malignancies (respiratory and gastrointestinal). Similarly, significant relationships with cancer death were observed between poor heart rate increase during exercise, poor decrease during recovery and greater heart-rate increase over time (p<0.0001 for all). Interpretation Resting and exercise heart rate had consistent, graded and highly significant associations with subsequent cancer mortality in men. PMID:21826196

    The Iowa record-linkage study was developed to investigate death rates in psychiatric patients, and involved computer matching of death certificates with a roster of patients. A list of all patients admitted to our hospital from 1972 through 1981 was obtained and after removing duplicate entries the list was pared to 5412 names. The record included multiple identifiers (e.g., name, gender, date-of-birth, hospital number). This information was then linked by computer with all Iowa death certificates for the same period; a total of 331 deaths were identified. Patients were assigned to a single psychiatric diagnostic category based on a computer program that reviewed each patient's clinical diagnoses and picked the one with the highest priority in a hierarchy we had created. Age and sex adjusted mortality tables were constructed, allowing us to compute expected numbers of deaths. Relative risk for premature death was greatest among women, and those under 20 years. Risk was associated with all psychiatric diagnoses and was significantly higher among patients of either gender with an organic mental disorder or schizophrenia; women with acute schizophrenia, depressive neuroses, alcoholism, drug abuse, and psychophysiological disorders; and men with neuroses. Death from natural causes, especially from heart disease, was significantly excessive among women, while death from accidents and suicides was excessive for both men and women. The overall SMR was 1.65 (P < 0.001). Most importantly, we found that the greatest excess of mortality occurred within the first 2 years following hospital discharge. Thus, we were able to demonstrate that risk of mortality in general, and of suicide specifically, differed according to age, gender, diagnosis, and portion of the follow-up. We have subsequently used this method to investigate specific risk factors associated with mortality in mood disorders, schizophrenia, and antisocial personality disorder. Findings from these studies are

    We calculated the annual rates of diving-related deaths among DAN-insured members in the period from 2000 to 2006 and investigated the effects of age and sex on death rate by logistic regression. We determined relative risks for divers < 50 and ≥ 50 years of age for drowning, arterial gas embolism, and cardiac incidents, the three most common disabling injuries associated with diving death. There were 1,141,367 insured member-years and 187 diving-related deaths. Males made up 64% of the members. Individuals ≥ 50 years of age constituted 31% of the fatalities. Insured mean age increased from 40 ± 12 to 43 ± 13 years over the seven-year study period. Annual fatality rates varied between 12.1 and 22.9 (average 16.4, 95% confidence intervals 14.2, 18.9) per 100,000 persons insured. The relative risk for male divers in their thirties was six times greater than the risk for female divers in the same age range. Fatality rates increased with age for both sexes, but the higher relative risk for males progressively decreased until the rates became similar for both sexes after age 60. Death associated with cardiac incidents was 12.9 times more likely in divers ≥ 50 years of age. We recommend that older divers adjust their participation in diving according to health status and physical fitness, maintain fitness with regular exercise, and abstain from diving in conditions likely to require unaccustomed physical activity.

    The division tracking dye, carboxyfluorescin diacetate succinimidyl ester (CFSE) is currently the most informative labeling technique for characterizing the division history of cells in the immune system. Gett and Hodgkin (Nat. Immunol. 1 (2000) 239-244) have proposed to normalize CFSE data by the 2-fold expansion that is associated with each division, and have argued that the mean of the normalized data increases linearly with time, t, with a slope reflecting the division rate p. We develop a number of mathematical models for the clonal expansion of quiescent cells after stimulation and show, within the context of these models, under which conditions this approach is valid. We compare three means of the distribution of cells over the CFSE profile at time t: the mean, [mu](t), the mean of the normalized distribution, [mu]2(t), and the mean of the normalized distribution excluding nondivided cells, .In the simplest models, which deal with homogeneous populations of cells with constant division and death rates, the normalized frequency distribution of the cells over the respective division numbers is a Poisson distribution with mean [mu]2(t)=pt, where p is the division rate. The fact that in the data these distributions seem Gaussian is therefore insufficient to establish that the times at which cells are recruited into the first division have a Gaussian variation because the Poisson distribution approaches the Gaussian distribution for large pt. Excluding nondivided cells complicates the data analysis because , and only approaches a slope p after an initial transient.In models where the first division of the quiescent cells takes longer than later divisions, all three means have an initial transient before they approach an asymptotic regime, which is the expected [mu](t)=2pt and . Such a transient markedly complicates the data analysis. After the same initial transients, the normalized cell numbers tend to decrease at a rate e-dt, where d is the death rate

    Little is known about the factors associated with undetermined death classifications among African Americans. In this study, the rates of undetermined deaths were assessed, the prevalence of missing information was estimated, and whether the circumstances preceding death differ by race were examined. Data were derived from the 2005-2008 National Violent Death Reporting System. African Americans had higher prevalence of missing information than Whites. African Americans classified as undetermined deaths were more likely to be older, women, never married/single, to have had a blood alcohol content at or above the legal limit, and to have had a substance abuse problem. The results suggest that racial differences in the preponderance and the type of evidence surrounding the death may affect death classification.

    We present the results of the first quantitative, whole-lifespan study of the relationship between age-specific neurolipofuscin concentration and natural mortality rate in any organism. In a convenient laboratory animal, the African migratory locust, Locusta migratoria, we find an unusual delayed-onset neurolipofuscin accumulation pattern that is highly correlated with exponentially accelerating age-specific Gompertz–Makeham death rates in both males (r=0.93, p=0.0064) and females (r=0.97, p=0.0052). We then test the conservation of this association by aggregating the locust results with available population-specific data for a range of other terrestrial, freshwater, marine, tropical and temperate arthropods whose longevities span three orders of magnitude. This synthesis shows that the strong association between neurolipofuscin deposition and natural mortality is a phylogenetically and environmentally widespread phenomenon (r=0.96, p<0.0001). These results highlight neurolipofuscin as a unique and outstanding integral biomarker of ageing. They also offer compelling evidence for the proposal that, in vital organs like the brain, either the accumulation of toxic garbage in the form of lipofuscin itself, or the particular molecular reactions underlying lipofuscinogenesis, including free-radical damage, are the primary events in senescence.

    A distinct seasonal pattern in total and cardiovascular death rates has been reported. The factors contributing to this pattern have not been fully explored. Seven locations (average total population 71,354,000) were selected where data were available including relatively warm, cold, and moderate temperatures. Over the period 2004 to 2009, there were 2,526,123 all-cause deaths, 838,264 circulatory deaths, 255,273 coronary heart disease deaths, and 135,801 ST-elevation myocardial infarction (STEMI) deaths. We used time series and multivariate regression modeling to explore the association between death rates and climatic factors (temperature, dew point, precipitation, barometric pressure), influenza levels, air pollution levels, hours of daylight, and day of week. Average seasonal patterns for all-cause and cardiovascular deaths were very similar across the 7 locations despite differences in climate. After adjusting for multiple covariates and potential confounders, there was a 0.49% increase in all-cause death rate for every 1°C decrease. In general, all-cause, circulatory, coronary heart disease and STEMI death rates increased linearly with decreasing temperatures. The temperature effect varied by location, including temperature's linear slope, cubic fit, positional shift on the temperature axis, and the presence of circulatory death increases in locally hot temperatures. The variable effect of temperature by location suggests that people acclimatize to local temperature cycles. All-cause and circulatory death rates also demonstrated sizable associations with influenza levels, dew point temperature, and barometric pressure. A greater understanding of how climate, temperature, and barometric pressure influence cardiovascular responses would enhance our understanding of circulatory and STEMI deaths.

  11. Trends in European liver death rates: implications for alcohol policy.

    Changing alcohol consumption has led to a three- to fivefold increase in liver deaths in the UK and Finland, and a three- to fivefold decrease in France and Italy. Increasing consumption from a low baseline has been driven by fiscal, marketing and commercial factors--some of which have occurred as a result of countries joining the EU. In contrast consumption has fallen from previously very high levels as a result of shifting social and cultural factors; a move from rural to urban lifestyles and increased health consciousness. The marketing drive in these countries has had to shift from a model based on quantity to one based on quality, which means that health gains have occurred alongside a steady improvement in the overall value of the wine industry. Fiscal incentives--minimum pricing, restricting cross border trade and more volumetric taxation could aid this shift. A healthier population and a healthy drinks industry are not incompatible.

    The objective of this study is to determine the effect of cause specific death rates on age specific death rates for Tamil Nadu rural females during the period 1970-75 in various age groups. 2 regression lines have been fitted. The age specific death rates were taken as dependent variables and time as an independent variable; the age-cause specific death rates were dependent variables and time was an independent variable. In the analysis, the ratio of regression coefficients of 2 regression lines gives the effect of age specific death rates due to the j-th cause in the i-th group. The trend of mortality in the age groups (0-4) and (5-14) declines over the period 1970-75 and increases in the age groups (15-34), (34-54) and 55 and older. The causes of declining mortality in the 0-4 age group are cough, fever, other clear symptoms and other causes. The %s of contribution for this decline are respectively 14%, 41%, 21% and 72% to the overall decline in that age group. The cause group violence and injury, digestive disorders and causes peculiar to infancy have contributed to increase in the 0-4 age group death rates. Digestive disorders, coughs and other causes have contributed to declining mortality in the 5-14 age group. The cause group accidents and injury, digestive disorders, other clear symptoms, child births and pregnancy and other causes are promoted to increase the mortality of the 15-34 age group. The causes contributing to the increasing trend of mortality in the 35-54 age group are violence and injury, digestive disorders, coughs, other clear symptoms, child births and pregnancy. Digestive disorders and other causes contributed to the mortality increase in the over 55 age group. PMID:12266915

    Background: South Africa (SA) is experiencing a rapid epidemiologic transition as a consequence of political, economic and social changes. In this study we described, based on hospital data, the mortality patterns of Non communicable Diseases (NCD), Communicable Diseases (CD), the NCD/CD ratios, and the trends of deaths. Methods: We conducted a cross-sectional survey of all deaths occurring in several public hospitals in the Eastern Cape Province of SA between 2002 and 2006. Causes of deaths were coded according to the ICD 10 Edition. Results: A total of 107380 admissions responded to the inclusion criteria between 2002 and 2006. The crude death rate was 4.3% (n=4566) with a mean age of 46±21 years and a sex ratio of 3.1 men (n=3453): 1 woman (n=1113). Out of all deaths, there were 62.9% NCD (n=2872) vs. 37.1% CD (n=1694) with NCD/CD ratio of 1.7. The ratio NCD/CD deaths in men was 1.3 (n=1951/1502) vs. NCD/CD deaths in women of 1.9 (n=735/378). The peak of deaths was observed in winter season. The majority of NCD deaths were at age of 30–64 years, whereas the highest rate of CD deaths was at age< 30 years. The trend of deaths including the majority of NCD, increased from 2002 to 2006. There was a tendency of increase in tuberculosis deaths, but a tendency of decrease in HIV/AIDS deaths was from 2002 to 2006. Conclusion: Non-communicable diseases are the leading causes of deaths in rural Eastern Cape province of SA facing Post-epidemiologic transition stages. We recommend overarching priority actions for the response to the Non-communicable Diseases: policy change, prevention, treatment, international cooperation, research, monitoring, accountability, and re-orientation of health systems.

  14. Rate of false conviction of criminal defendants who are sentenced to death

    The rate of erroneous conviction of innocent criminal defendants is often described as not merely unknown but unknowable. There is no systematic method to determine the accuracy of a criminal conviction; if there were, these errors would not occur in the first place. As a result, very few false convictions are ever discovered, and those that are discovered are not representative of the group as a whole. In the United States, however, a high proportion of false convictions that do come to light and produce exonerations are concentrated among the tiny minority of cases in which defendants are sentenced to death. This makes it possible to use data on death row exonerations to estimate the overall rate of false conviction among death sentences. The high rate of exoneration among death-sentenced defendants appears to be driven by the threat of execution, but most death-sentenced defendants are removed from death row and resentenced to life imprisonment, after which the likelihood of exoneration drops sharply. We use survival analysis to model this effect, and estimate that if all death-sentenced defendants remained under sentence of death indefinitely, at least 4.1% would be exonerated. We conclude that this is a conservative estimate of the proportion of false conviction among death sentences in the United States. PMID:24778209

  17. Natural background radioactive carbon and the natural death rate of people.

    2006-01-01

    A brief analysis of the known data on the potential danger of radiocarbon incorporation into DNA structure shows that the great genetic importance of transmutational transformations of DNA-incorporated 14C is theoretically and experimentally proved. This effect exists both in huge and small radiation doses (similar to doses of 14C natural background radiation). Therefore, the human death rate can be assumed to be dependent on natural and anthropogenous fluctuations of atmospheric 14C. Calculation methods of the age parameter dynamics of the natural human death rate are offered. It is shown that when calculating the parameters of the natural death rate, the use of Gompertz's formula is reasonable provided that the data on the general death rate are taken for the age interval "60 to 85 years." The ratios reflecting the regular and casual errors of the parameters R and a of Gompertz's equation, caused by people's casual deaths, were determined. A comparison of the historical dynamics of people's natural death rates in the last 150 years with the variations of 14C of the natural background during the same period showed that these are coordinated phenomena, the strong correlation of which indicates the possibility of their functional dependence. The 14C-concentration increase in an organism is the result of its increase in the surrounding biospheric composition, causing an increase in the natural death rate and vice versa: The increase of a person's life expectancy is caused by a decrease of 14C concentration.

    High death rates are reported in health care workers (HCWs) and teachers in urban areas of Malawi. The present study was carried out to determine the annual death rate in HCWs and primary school teachers working in semi-urban and rural areas of Malawi, and to try to ascertain the main causes of death. Forty district and mission hospitals in Malawi were visited. A record was made of the number of clinical and nursing-based HCWs in each hospital in 1999, the number of deaths in that calendar year and reported causes of death. A record was also made of the number of teachers working in 4 primary schools nearest to each hospital in 1999, the number of deaths in that calendar year and reported causes of death. There were 2979 HCWs, of whom 60 (2.0%) died. There were 4367 teachers of whom 101 (2.3%) died. Annual death rates, calculated per 100,000 people, were significantly higher in male HCWs compared with female HCWs (2495 versus 1770, RR 1.17, 95% CI 1.14-1.20, P < 0.001), and significantly higher in female teachers compared with male teachers (2521 versus 1934, RR 1.14, 95% CI 1.11-1.17, P < 0.001). In male HCWs and teachers the highest death rates were in those aged 35-44 years. In female HCWs and teachers, the highest death rates were in those aged 25-34 years and 35-44 years, respectively. Reported causes of death in HCWs were tuberculosis (TB) in 47%, chronic illness in 45% and acute illness in the remainder, while in teachers the causes were TB in 27%, chronic illness in 49% and acute illness in 25%. Chronic illness, thought to be due to AIDS, and TB were the common causes of death. The current high death rates from AIDS and TB will have a crippling toll on the health and education sectors, and effective ways of reducing these death rates must be found.

  10. Effects of local extrinsic mortality rate, crime and sex ratio on preventable death in Northern Ireland

    PubMed Central

    Uggla, Caroline; Mace, Ruth

    2015-01-01

    Background and objectives: Individual investment in health varies greatly within populations and results in significant differences in the risk of preventable death. Life history theory predicts that individuals should alter their investment in health (somatic maintenance) in response to ecological cues that shift the perceived fitness payoffs to such investments. However, previous research has failed to isolate the effects of different ecological factors on preventable death, and has often relied on macro-level data without individual controls. Here, we test some key predictions concerning the local ecology—that higher extrinsic mortality rate (EMR), crime rate and mate-scarcity (male/female-biased sex ratio) at the ward-level—will be associated with a higher risk of preventable death. Methodology: We use census-based data from Northern Ireland (n = 927 150) on preventable death during an 8.7-year period from the 2001 Census and run Cox regressions for (i) accident/suicide or alcohol-related death and (ii) deaths from preventable diseases, for men and women separately, controlling for a wide range of individual variables. Results: We find evidence of ward-level EMR and crime rate being positively associated with preventable death among men, particularly men with low socioeconomic position. There was a tentative relationship between male-biased sex ratio and preventable death among women, but not among men. Conclusion and implications: Both behaviours that might lead to ‘risky’ death and health neglect might be adaptive responses to local ecologies. Efforts to reduce crime might be as effective as those to reduce extrinsic mortality, and both could have positive effects on various health behaviours. PMID:26338679

  11. Death and injury rates of U.S. military personnel in Iraq.

    PubMed

    Goldberg, Matthew S

    2010-04-01

    In the first 6.5 years of Operation Iraqi Freedom (OIF), U.S. military casualties exceeded 3,400 hostile deaths, 800 nonhostile deaths (due to disease, nonbattle injury, and other causes), and over 31,000 troops wounded in action. Casualty rates in Iraq have been considerably lower that during the Vietnam conflict, and a greater proportion of troops wounded in Iraq survive their wounds. Before the surge in troop levels that began in early 2007, the survival rate was 90.4% in Iraq as compared to 86.5% in Vietnam. Wounded-in-action rates increased during the first few months of the surge, but declined below presurge levels after the number of U.S. brigades in Iraq climbed from 15 to its maximum level of 20. Wounds during the surge were somewhat more lethal than previously, but because there were fewer wounding incidents the net effect was a reduction in the hostile death rate.

  14. Blood pressure and heart rate variability and baroreflex sensitivity before and after brain death

    PubMed Central

    Conci, F; Di, R; Castiglioni, P

    2001-01-01

    OBJECTIVES—To evaluate spontaneous blood pressure and heart rate variability and spontaneous baroreflex sensitivity before and after brain death.
METHODS—Spontaneous variability of arterial blood pressure and heart rate—estimated by power spectra of systolic (SBP) and diastolic blood pressure (DBP) and pulse interval (PI)—and spontaneous baroreflex sensitivity (BRS)—estimated by the alpha index and the sequence technique—were evaluated in 11 patients twice: shortly before and 1 hour after the onset of brain death.
RESULTS—Significant spectral changes occurred after brain death: a general power reduction in PI spectra; a shift of SBP, DBP and PI powers toward the lower frequencies, resulting in a greater slope of the "1/f" spectral trends; and a marked reduction of SBP and DBP powers (-93%) and of SBP-PI coherence (−63%) at 0.1Hz. The estimated average BRS was relatively high before brain death (around 11 ms/mm Hg), and fell close to 0 or even was not detectable at all after brain death.
CONCLUSIONS—Parameters describing spontaneous blood pressure and heart rate variability and indexes reflecting the baroreflex function, which were relatively normal up to a few hours before brain death, underwent marked changes with the onset of brain death. All the changes found are likely to reflect the cessation of activity of the cardiovascular brain stem centres. These findings indicate that techniques of blood pressure and heart rate spectral analysis and of dynamic assessment of baroreflex sensitivity may be useful to complement the diagnosis of brain stem death.

    2013-09-01

    Cancer is one of the principal causes of death in Malaysia. This study was performed to determine the pattern of rate of cancer deaths at a public hospital in Malaysia over an 11 year period from year 2001 to 2011, to determine the best fitted model of forecasting the rate of cancer deaths using Univariate Modeling and to forecast the rates for the next two years (2012 to 2013). The medical records of the death of patients with cancer admitted at this Hospital over 11 year's period were reviewed, with a total of 663 cases. The cancers were classified according to 10th Revision International Classification of Diseases (ICD-10). Data collected include socio-demographic background of patients such as registration number, age, gender, ethnicity, ward and diagnosis. Data entry and analysis was accomplished using SPSS 19.0 and Minitab 16.0. The five Univariate Models used were Naïve with Trend Model, Average Percent Change Model (ACPM), Single Exponential Smoothing, Double Exponential Smoothing and Holt's Method. The overall 11 years rate of cancer deaths showed that at this hospital, Malay patients have the highest percentage (88.10%) compared to other ethnic groups with males (51.30%) higher than females. Lung and breast cancer have the most number of cancer deaths among gender. About 29.60% of the patients who died due to cancer were aged 61 years old and above. The best Univariate Model used for forecasting the rate of cancer deaths is Single Exponential Smoothing Technique with alpha of 0.10. The forecast for the rate of cancer deaths shows a horizontally or flat value. The forecasted mortality trend remains at 6.84% from January 2012 to December 2013. All the government and private sectors and non-governmental organizations need to highlight issues on cancer especially lung and breast cancers to the public through campaigns using mass media, media electronics, posters and pamphlets in the attempt to decrease the rate of cancer deaths in Malaysia.

    Deaths from Plasmodium knowlesi malaria have been linked to delayed parenteral treatment. In Malaysia, early intravenous artesunate is now recommended for all severe malaria cases. We describe P. knowlesi fatalities in Sabah, Malaysia, during 2012-2014 and report species-specific fatality rates based on 2010-2014 case notifications. Sixteen malaria-associated deaths (caused by PCR-confirmed P. knowlesi [7], P. falciparum [7], and P. vivax [1] and microscopy-diagnosed "P. malariae" [1]) were reported during 2012-2014. Six patients with severe P. knowlesi malaria received intravenous artesunate at hospital admission. For persons ≥15 years of age, overall fatality rates during 2010-2014 were 3.4, 4.2, and 1.0 deaths/1,000 P. knowlesi, P. falciparum, and P. vivax notifications, respectively; P. knowlesi-associated fatality rates fell from 9.2 to 1.6 deaths/1,000 notifications. No P. knowlesi-associated deaths occurred among children, despite 373 notified cases. Although P. knowlesi malaria incidence is rising, the notification-fatality rate has decreased, likely due to improved use of intravenous artesunate.

  17. QuickStats: Age-Adjusted Death Rates* for Top Five Causes of Cancer Death,(†) by Race/Hispanic Ethnicity - United States, 2014.

    PubMed

    2016-01-01

    In 2014, the top five causes of cancer deaths for the total population were lung, colorectal, female breast, pancreatic, and prostate cancer. The non-Hispanic black population had the highest age-adjusted death rates for each of these five cancers, followed by non-Hispanic white and Hispanic groups. The age-adjusted death rate for lung cancer, the leading cause of cancer death in all groups, was 42.1 per 100,000 standard population for the total population, 45.4 for non-Hispanic white, 45.7 for non-Hispanic black, and 18.3 for Hispanic populations.

    OBJECTIVES: To examine trends in child mortality from unintentional injury between 1985 and 1992 and to find how changes in modes of travel contributed to these trends. DESIGN: Poisson regression modelling using data from death certificates, censuses, and national travel surveys. SETTING: England and Wales. SUBJECTS: Resident children aged 0-14. MAIN OUTCOME MEASURES: Deaths from unintentional injury and poisoning. RESULTS: Child deaths from injury declined by 34% (95% confidence interval 28% to 40%) per 100,000 population between 1985 and 1992. Substantial decreases in each of the leading causes of death from injury contributed to this overall decline. On average, children walked and cycled less distance and travelled substantially more miles by car in 1992 compared with 1985. Deaths from road traffic accidents declined for pedestrians by 24% per mile walked and for cyclists by 20% per mile cycled, substantially less than the declines per 100,000 population of 37% and 38% respectively. In contrast, deaths of occupants of motor vehicles declined by 42% per mile travelled by car compared with a 21% decline per 100,000 population. CONCLUSIONS: If trends in child mortality from injury continue the government's target to reduce the rate by 33% by the year 2005 will be achieved. A substantial proportion of the decline in pedestrian traffic and pedal cycling deaths, however, seems to have been achieved at the expense of children's walking and cycling activities. Changes in travel patterns may exact a considerable price in terms of future health problems. PMID:9116546

  19. A predator-prey model with generic birth and death rates for the predator.

    PubMed

    Terry, Alan J

    2014-02-01

    We propose and study a predator-prey model in which the predator has a Holling type II functional response and generic per capita birth and death rates. Given that prey consumption provides the energy for predator activity, and that the predator functional response represents the prey consumption rate per predator, we assume that the per capita birth and death rates for the predator are, respectively, increasing and decreasing functions of the predator functional response. These functions are monotonic, but not necessarily strictly monotonic, for all values of the argument. In particular, we allow the possibility that the predator birth rate is zero for all sufficiently small values of the predator functional response, reflecting the idea that a certain level of energy intake is needed before a predator can reproduce. Our analysis reveals that the model exhibits the behaviours typically found in predator-prey models - extinction of the predator population, convergence to a periodic orbit, or convergence to a co-existence fixed point. For a specific example, in which the predator birth and death rates are constant for all sufficiently small or large values of the predator functional response, we corroborate our analysis with numerical simulations. In the unlikely case where these birth and death rates equal the same constant for all sufficiently large values of the predator functional response, the model is capable of structurally unstable behaviour, with a small change in the initial conditions leading to a more pronounced change in the long-term dynamics.

    The Fock-space approach to the solution of master equations for one-step Markov processes is reconsidered. It is shown that in birth-death processes with an absorbing state at the bottom of the occupation-number spectrum and occupation-number independent annihilation probability of occupation-number fluctuations give rise to rate equations drastically different from the polynomial form typical of birth-death processes. The fluctuation-induced rate equations with the characteristic exponential terms are derived for Mikhailov’s ecological model and Lanchester’s model of modern warfare.

    Thermal death kinetics of Conogethes punctiferalis (Guenée) (Lepidoptera: Pyralidae) at different life stages, heating rate, and temperature is essential for developing postharvest treatments to control pests in chestnuts. Using a heating block system (HBS), the most heat-tolerant life stage of C. punctiferalis and the effects of heating rate (0.1, 0.5, 1, 5, and 10°C/min) on insect mortality were determined. The thermal death kinetic data of fifth-instar C. punctiferalis were obtained at temperatures between 44 and 50°C at a heating rate of 5°C/min. The results showed that the relative heat tolerance of C. punctiferalis was found to be fifth instars>pupae> third instars> eggs. To avoid the enhanced thermal tolerance of C. punctiferalis at low heating rates (0.1 or 0.5°C/min), a high heating rate of 5°C/min was selected to simulate the fast radio frequency heating in chestnuts and further determine the thermal death kinetic data. Thermal death curves of C. punctiferalis followed a 0th-order kinetic reaction model. The minimum exposure time to achieve 100% mortality was 55, 12, 6, and 3 min at 44, 46, 48, and 50°C, respectively. The activation energy for controlling C. punctiferalis was 482.15 kJ/mol with the z value of 4.09°C obtained from the thermal death-time curve. The information provided by thermal death kinetics for C. punctiferalis is useful in developing effective postharvest thermal treatment protocols for disinfesting chestnuts.

    Background The respiratory tract is a major target of exposure to air pollutants, and respiratory diseases are associated with both short- and long-term exposures. We hypothesized that improved air quality in North Carolina was associated with reduced rates of death from respiratory diseases in local populations. Materials and methods We analyzed the trends of emphysema, asthma, and pneumonia mortality and changes of the levels of ozone, sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and particulate matters (PM2.5 and PM10) using monthly data measurements from air-monitoring stations in North Carolina in 1993–2010. The log-linear model was used to evaluate associations between air-pollutant levels and age-adjusted death rates (per 100,000 of population) calculated for 5-year age-groups and for standard 2000 North Carolina population. The studied associations were adjusted by age group-specific smoking prevalence and seasonal fluctuations of disease-specific respiratory deaths. Results Decline in emphysema deaths was associated with decreasing levels of SO2 and CO in the air, decline in asthma deaths–with lower SO2, CO, and PM10 levels, and decline in pneumonia deaths–with lower levels of SO2. Sensitivity analyses were performed to study potential effects of the change from International Classification of Diseases (ICD)-9 to ICD-10 codes, the effects of air pollutants on mortality during summer and winter, the impact of approach when only the underlying causes of deaths were used, and when mortality and air-quality data were analyzed on the county level. In each case, the results of sensitivity analyses demonstrated stability. The importance of analysis of pneumonia as an underlying cause of death was also highlighted. Conclusion Significant associations were observed between decreasing death rates of emphysema, asthma, and pneumonia and decreases in levels of ambient air pollutants in North Carolina.

    Released prisoners face high risk of early mortality. The risk of violent death, specifically homicide and suicide, are addressed in this study. Data on inmates released from the North Carolina Division of Adult Corrections (N = 476) matched to the Violent Death Reporting System are analyzed to estimate rates and demographic and criminal justice-related predictors. Violent death rates for persons released from prison were more than 7 times higher than for the general adult population. Results from multinomial logistic regression indicate decreased homicide risk for every year of age, whereas male gender and minority race increased risk. For suicide, minority race, release without supervision, and substance abuse treatment in prison decreased fatality risk. By contrast, a history of mental illness increased suicide risk. Implications for practice and research are discussed. PMID:26440107

    2010-04-01

    In the first 6.5 years of Operation Iraqi Freedom (OIF), U.S. military casualties exceeded 3,400 hostile deaths, 800 nonhostile deaths (due to disease, nonbattle injury, and other causes), and over 31,000 troops wounded in action. Casualty rates in Iraq have been considerably lower that during the Vietnam conflict, and a greater proportion of troops wounded in Iraq survive their wounds. Before the surge in troop levels that began in early 2007, the survival rate was 90.4% in Iraq as compared to 86.5% in Vietnam. Wounded-in-action rates increased during the first few months of the surge, but declined below presurge levels after the number of U.S. brigades in Iraq climbed from 15 to its maximum level of 20. Wounds during the surge were somewhat more lethal than previously, but because there were fewer wounding incidents the net effect was a reduction in the hostile death rate. PMID:20446496

    Aims To assess the relationships between early and late antemortem measures of dementia severity and Alzheimer disease (AD) neuropathology severity. Methods 40 residents of a nursing home, average age at death 82.0, participated in this longitudinal cohort study with postmortem assessment. Severity of dementia was measured by Clinical Dementia Rating (CDR) at two time points, averaging 4.5 and 1.0 years before death. Densities of postmortem neuritic plaques (NPs) and neurofibrillary tangles (NFTs) were measured in the cerebral cortex, hippocampus, and entorhinal cortex. Results For most brain areas, both early and late CDRs were significantly associated with NPs and NFTs. CDRs assessed proximal to death predicted NFTs beyond the contribution of early CDRs. NPs were predicted by both early and late CDRs. NPs were predictive of both early and late CDRs after controlling for NFTs. NFTs were only associated significantly with late CDR in the cerebral cortex after controlling for NPs. Conclusions Even if assessed several years before death, dementia severity is associated with AD neuropathology. NPs are more strongly associated with dementia severity than NFTs. NFTs consistently associate better with late than early CDR, suggesting that these neuropathological changes may occur relatively later in the course of the disease. PMID:18367838

    From 1950 to 1977 the age-adjusted cancer death rates for nonwhite men in the United States rose an astonishing 63.2 percent, while rates for white men increased 22.2 percent and fell slightly for women of both races. The bulk of this increase can be accounted for by cancer of the lung. As a serious health problem that is increasing in severity, cancer in black men deserves close attention and definitive action. This discussion focuses on basic epidemiological relationships in the origins of this epidemic, particularly in regard to the relative importance of occupation, cigarette smoking, and social class.

  10. Enhanced recovery program for hip and knee replacement reduces death rate

    PubMed Central

    2011-01-01

    Background and purpose Multimodal techniques can aid early rehabilitation and discharge of patients following primary joint replacement. We hypothesized that this not only reduces the economic burden of joint replacement by reducing length of stay, but also helps in reduction of early complications. Patients and methods We evaluated 4,500 consecutive unselected total hip replacements and total knee replacements regarding length of hospital stay, mortality, and perioperative complications. The first 3,000 underwent a traditional protocol while the other 1,500 underwent an enhanced recovery protocol involving behavioral, pharmacological, and procedural modifications. Results There was a reduction in 30-day death rate (0.5% to 0.1%, p = 0.02) and 90-day death rate (0.8% to 0.2%, p = 0.01). The median length of stay decreased from 6 days to 3 days (p < 0.001), resulting in a saving of 5,418 bed days. Requirement for blood transfusion was reduced (23% to 9.8%, p < 0.001). There was a trend of a reduced rate of 30-day myocardial infarction (0.8% to 0.5%. p = 0 .2) and stroke (0.5% to 0.2%, p = 0.2). The 60-day deep vein thrombosis figures (0.8% to 0.6%, p = 0.5) and pulmonary embolism figures (1.2% to 1.1%, p = 0.9) were similar. Re-admission rate remained unchanged during the period of the study (4.7% to 4.8%, p = 0.8). Interpretation This large observational study of unselected consecutive hip and knee arthroplasty patients shows a substantial reduction in death rate, reduced length of stay, and reduced transfusion requirements after the introduction of a multimodal enhanced recovery protocol.

  11. Diabetes death rates among youths aged ≤ 19 years--United States, 1968-2009.

    PubMed

    2012-11-01

    Although diabetes mellitus most often is diagnosed in adulthood, it remains one of the most common serious chronic diseases of childhood. Youths with diabetes are at risk for diabetes-related mortality because of acute complications that can result from the condition, including diabetic ketoacidosis and hypoglycemia. In the United States in 2010, an estimated 215,000 persons aged ≤ 19 years had diagnosed diabetes. Medical care for diabetes has improved considerably in recent decades, leading to improved survival rates. However, recent trends in diabetes death rates among youths aged <10 years and 10-19 years in the United States have not been reported. To assess these trends, CDC analyzed data from the National Vital Statistics System for deaths in the United States with diabetes listed as the underlying cause during 1968-2009. This report highlights the results of that analysis, which found that diabetes-related mortality decreased 61%, from an annual rate of 2.69 per million for the period 1968-1969 to a rate of 1.05 per million in 2008-2009. The percentage decrease was greater among youths aged <10 years (78%) than among youths aged 10-19 years (52%). These findings demonstrate improvements in diabetes mortality among youths but also indicate a need for continued improvement in diabetes diagnosis and care. PMID:23114253

  13. Effect of marital status on death rates. Part 2: Transient mortality spikes

    NASA Astrophysics Data System (ADS)

    Richmond, Peter; Roehner, Bertrand M.

    2016-05-01

    We examine what happens in a population when it experiences an abrupt change in surrounding conditions. Several cases of such "abrupt transitions" for both physical and living social systems are analyzed from which it can be seen that all share a common pattern. First, a steep rising death rate followed by a much slower relaxation process during which the death rate decreases as a power law. This leads us to propose a general principle which can be summarized as follows: "Any abrupt change in living conditions generates a mortality spike which acts as a kind of selection process". This we term the Transient Shock conjecture. It provides a qualitative model which leads to testable predictions. For example, marriage certainly brings about a major change in personal and social conditions and according to our conjecture one would expect a mortality spike in the months following marriage. At first sight this may seem an unlikely proposition but we demonstrate (by three different methods) that even here the existence of mortality spikes is supported by solid empirical evidence.

  14. Fetal death and reduced birth rates associated with exposure to lead-contaminated drinking water.

    PubMed

    Edwards, Marc

    2014-01-01

    This ecologic study notes that fetal death rates (FDR) during the Washington DC drinking water "lead crisis" (2000-2004) peaked in 2001 when water lead levels (WLLs) were highest, and were minimized in 2004 after public health interventions were implemented to protect pregnant women. Changes in the DC FDR vs neighboring Baltimore City were correlated to DC WLL (R(2) = 0.72). Birth rates in DC also increased versus Baltimore City and versus the United States in 2004-2006, when consumers were protected from high WLLs. The increased births in DC neighborhoods comparing 2004 versus 2001 was correlated to the incidence of lead pipes (R(2) = 0.60). DC birth rates from 1999 to 2007 correlated with proxies for maternal blood lead including the geometric mean blood lead in DC children (R(2) = 0.68) and the incidence of lead poisoning in children under age 1.3 years (R(2) = 0.64). After public health protections were removed in 2006, DC FDR spiked in 2007-2009 versus 2004-2006 (p < 0.05), in a manner consistent with high WLL health risks to consumers arising from partial lead service line replacements, and DC FDR dropped to historically low levels in 2010-2011 after consumers were protected and the PSLR program was terminated. Re-evaluation of a historic construction-related miscarriage cluster in the USA Today Building (1987-1988), demonstrates that high WLLs from disturbed plumbing were a possible cause. Overall results are consistent with prior research linking increased lead exposure to higher incidence of miscarriages and fetal death, even at blood lead elevations (≈5 μg/dL) once considered relatively low.

    Notoginseng (Panax notoginseng), a valuable herbal medicine, has high death rates in continuous cropping systems. Variation in the soil microbial community is considered the primary cause of notoginseng mortality, although the taxa responsible for crop failure remains unidentified. This study used high-throughput sequencing methods to characterize changes in the microbial community and screen microbial taxa related to the death rate. Fungal diversity significantly decreased in soils cropped with notoginseng for three years. The death rate and the fungal diversity were significantly negatively correlated, suggesting that fungal diversity might be a potential bioindicator of soil health. Positive correlation coefficients revealed that Burkholderiales, Syntrophobacteraceae, Myrmecridium, Phaeosphaeria, Fusarium, and Phoma were better adapted to colonization of diseased plants. The relative abundance of Fusarium oxysporum (R = 0.841, P < 0.05) and Phaeosphaeria rousseliana (R = 0.830, P < 0.05) were positively associated with the death rate. F. oxysporum was a pathogen of notoginseng root-rot that caused seedling death. Negative correlation coefficients indicated that Thermogemmatisporaceae, Actinosynnemataceae, Hydnodontaceae, Herpotrichiellaceae, and Coniosporium might be antagonists of pathogens, and the relative abundance of Coniosporium perforans was negatively correlated with the death rate. Our findings provide a dynamic overview of the microbial community and present a clear scope for screening beneficial microbes and pathogens of notoginseng. PMID:27549984

    The purpose of this study was to determine whether there were changes in death rates when a local football team participated in the Super Bowl. Los Angeles (LA) played in the Super Bowl twice: on January 20, 1980 (LA Rams vs Pittsburgh Steelers, which LA lost), and on January 22, 1984 (LA Raiders vs Washington Redskins, which LA won). Data from LA County were analyzed for all-cause and circulatory death rates for the Super Bowl and the following 14 days when LA played (Super Bowl-related days) and control days (from January 15 to the end of February for 1980 to 1983 and 1984 to 1988). The Super Bowl-related days during LA's losing 1980 game were associated with higher daily death rates in LA County (per 100,000 population) for all deaths (2.4482 vs 2.0968 for control days, p <0.0001), circulatory deaths (1.3024 vs 1.0665 for control days, p <0.0001), deaths from ischemic heart disease (0.8551 vs 0.7143 for control days, p <0.0001), and deaths from acute myocardial infarctions (0.2710 vs 0.2322 for control days, p = 0.0213). In contrast, the Super Bowl-related days during the winning 1984 game were associated with a lower rate of all-cause death (2.1870 vs 2.3205 for control days, p = 0.0302). In conclusion, the emotional stress of loss and/or the intensity of a game played by a sports team in a highly publicized rivalry such as the Super Bowl can trigger total and cardiovascular deaths.

    Objectives Our goal was to identify if there might be advantages to combining two major public health concerns, i.e., homicides and suicides, in an analysis with well-established macro-level economic determinants, i.e., unemployment and inequality. Methods Mortality data, unemployment statistics, and inequality measures were obtained for 40 countries for the years 1962–2008. Rates of combined homicide and suicide, ratio of suicide to combined violent death, and ratio between homicide and suicide were graphed and analyzed. A fixed effects regression model was then performed for unemployment rates and Gini coefficients on homicide, suicide, and combined death rates. Results For a majority of nation states, suicide comprised a substantial proportion (mean 75.51%; range 0–99%) of the combined rate of homicide and suicide. When combined, a small but significant relationship emerged between logged Gini coefficient and combined death rates (0.0066, p < 0.05), suggesting that the combined rate improves the ability to detect a significant relationship when compared to either rate measurement alone. Results were duplicated by age group, whereby combining death rates into a single measure improved statistical power, provided that the association was strong. Conclusions Violent deaths, when combined, were associated with an increase in unemployment and an increase in Gini coefficient, creating a more robust variable. As the effects of macro-level factors (e.g., social and economic policies) on violent death rates in a population are shown to be more significant than those of micro-level influences (e.g., individual characteristics), these associations may be useful to discover. An expansion of socioeconomic variables and the inclusion of other forms of violence in future research could help elucidate long-term trends. PMID:26028985

    Background Bats receive increasing attention in infectious disease studies, because of their well recognized status as reservoir species for various infectious agents. This is even more important, as bats with their capability of long distance dispersal and complex social structures are unique in the way microbes could be spread by these mammalian species. Nevertheless, infection studies in bats are predominantly limited to the identification of specific pathogens presenting a potential health threat to humans. But the impact of infectious agents on the individual host and their importance on bat mortality is largely unknown and has been neglected in most studies published to date. Methodology/Principal Findings Between 2002 and 2009, 486 deceased bats of 19 European species (family Vespertilionidae) were collected in different geographic regions in Germany. Most animals represented individual cases that have been incidentally found close to roosting sites or near human habitation in urban and urban-like environments. The bat carcasses were subjected to a post-mortem examination and investigated histo-pathologically, bacteriologically and virologically. Trauma and disease represented the most important causes of death in these bats. Comparative analysis of pathological findings and microbiological results show that microbial agents indeed have an impact on bats succumbing to infectious diseases, with fatal bacterial, viral and parasitic infections found in at least 12% of the bats investigated. Conclusions/Significance Our data demonstrate the importance of diseases and infectious agents as cause of death in European bat species. The clear seasonal and individual variations in disease prevalence and infection rates indicate that maternity colonies are more susceptible to infectious agents, underlining the possible important role of host physiology, immunity and roosting behavior as risk factors for infection of bats.

    Objectives. We assessed the 5-year, nationwide impact on road deaths of the raise in the speed limit (November 1, 1993) on 3 major interurban highways in Israel from 90 to 100 kph. Methods. We compared before–after trends in deaths as well as case fatality—an outcome independent of exposure (defined as vehicle-kilometers traveled). Results. After the raise, speeds rose by 4.5%–9.1%. Over 5 years, there was a sustained increase in deaths (15%) and case fatality rates (38%) on all interurban roads. Corresponding increases in deaths (13%) and case fatality (24%) on urban roads indicated “speed spillover.” Conclusions. Immediate increases in case fatality predicted and tracked the sustained increase in deaths from increased speeds of impact. Newtonian fourth power models predicted the effects of “small” increases in speed on large rises in case fatality rates. Countermeasures and congestion reduced the impact on deaths and case-fatality rates by more than half. PMID:15054007

    The death toll by heatstroke in Japan, especially in Kanto region, has sharply increased since 1994 together with large interannual variability. The surface air temperature and humidity observed during boreal summers of 1980-2010 were examined to understand the role of climate in the death toll. The extremely hot days, when the daily maximum temperature exceeds 35°C, are more strongly associated with the death toll than the conventional Wet Bulb Globe Temperature index. The extremely hot days tend to be associated with El Niño/Southern Oscillation or the Indian Ocean Dipole, suggesting a potential link with tropical climate variability to the heatstroke related deaths. Also, the influence of these climate modes on the death toll has strengthened since 1994 probably related to global warming. It is possible to develop early warning systems based on seasonal climate predictions since recent climate models show excellent predictability skills for those climate modes.

  8. Correlation of Alzheimer's disease death rates with historical per capita personal income in the USA.

    Alzheimer's disease (AD) is a progressive degenerating disease of complex etiology. A variety of risk factors contribute to the chance of developing AD. Lifestyle factors, such as physical, mental and social activity, education, and diet all affect the susceptibility to developing AD. These factors are in turn related to the level of personal income. Lower income usually coincides with lower level of education, lesser mental, leisure-social and physical activity, and poorer diet. In the present paper, we have analyzed the correlation of historical (1929-2011) per capita personal income (PCPI) for all states of the USA with corresponding age-adjusted AD death rates (AADR) for years 2000, 2005 and 2008. We found negative correlations in all cases, the highest one (R ≈ -0.65) for the PCPIs in the year 1970 correlated against the AADRs in 2005. From 1929 to 2005 the R value varies in an oscillatory manner, with the strongest correlations in 1929, 1970, 1990 and the weakest in 1950, 1980, 1998. Further analysis indicated that this oscillatory behavior of R is not artificially related to the economic factors but rather to delayed biological consequences associated with personal income. We conclude that the influence of the income level on the AD mortality in 2005 was the highest in the early years of life of the AD victims. Overall, the income had a significant, lifelong, albeit constantly decreasing, influence on the risk of developing AD. We postulate that the susceptibility of a population to late-onset AD (LOAD) is determined to a large extent by the history of income-related modifiable lifestyle risk factors. Among these risk factors, inappropriate diet has a significant contribution.

    Over the past two decades the number of opioid pain relievers sold in the United States rose dramatically. This rise in sales was accompanied by an increase in opioid-related overdose deaths. In response, forty-nine states (all but Missouri) created prescription drug monitoring programs to detect high-risk prescribing and patient behaviors. Our objectives were to determine whether the implementation or particular characteristics of the programs were effective in reducing opioid-related overdose deaths. In adjusted analyses we found that a state's implementation of a program was associated with an average reduction of 1.12 opioid-related overdose deaths per 100,000 population in the year after implementation. Additionally, states whose programs had robust characteristics-including monitoring greater numbers of drugs with abuse potential and updating their data at least weekly-had greater reductions in deaths, compared to states whose programs did not have these characteristics. We estimate that if Missouri adopted a prescription drug monitoring program and other states enhanced their programs with robust features, there would be more than 600 fewer overdose deaths nationwide in 2016, preventing approximately two deaths each day.

    Background: Published death rates for persons with HIV have not distinguished deaths due to HIV from deaths due to other causes. Cause-specific death rates would allow better assessment of care needs. Methods: Using data reported to the US national HIV surveillance system, we examined a) associations between selected decedent characteristics and causes of death during 2007-2011, b) trends in rates of death due to underlying causes among persons with AIDS during 1990-2011, and among all persons with diagnosed HIV infection (with or without AIDS) during 2000-2011. Results: During 2007-2011, non-HIV-attributable causes of death with the highest rates per 1,000 person-years were heart disease (2.0), non-AIDS cancers other than lung cancer (1.4), and accidents (0.8). During 1990-2011, among persons with AIDS, the annual rate of death due to HIV-attributable causes decreased by 89% (from 122.0 to 13.2), and the rate due to non-HIV-attributable-causes decreased by 57% (from 20.0 to 8.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 11% to 43%. During 2000-2011, among persons with HIV infection, the rate of death due to HIV-attributable causes decreased by 69% (from 26.4 to 8.3), and the rate due to non-HIV-attributable causes decreased by 28% (from 10.5 to 7.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 25% to 48%. Conclusion: Among HIV-infected persons, as rates of death due to HIV-attributable causes decreased, rates due to non-HIV-attributable causes also decreased, but the percentages of deaths due to non-HIV-attributable causes, such as heart disease and non-AIDS cancers increased.

    The Farr-Bertillon law says that for all age-groups the death rate of married people is lower than the death rate of people who are not married (i.e. single, widowed or divorced). Although this law has been known for over 150 years, it has never been established with well-controlled accuracy (e.g. error bars). This even let some authors argue that it was a statistical artifact. It is true that the data must be selected with great care, especially for age groups of small size (e.g. widowers under 25). The observations reported in this paper were selected in the way experiments are designed in physics, that is to say with the objective of minimizing error bars. Data appropriate for mid-age groups may be unsuitable for young age groups and vice versa. The investigation led to the following results. (1) The FB effect is very similar for men and women, except that (at least in western countries) its amplitude is 20% higher for men. (2) There is a marked difference between single/divorced persons on the one hand, for whom the effect is largest around the age of 40, and widowed persons on the other hand, for whom the effect is largest around the age of 25. (3) When different causes of death are distinguished, the effect is largest for suicide and smallest for cancer. For heart disease and cerebrovascular accidents, the fact of being married divides the death rate by 2.2 compared to non-married persons. (4) For young widowers the death rates are up to 10 times higher than for married persons of same age. This extreme form of the FB effect will be referred to as the "young widower effect". Chinese data are used to explore this effect more closely. A possible connection between the FB effect and Martin Raff's "Stay alive" effect for the cells in an organism is discussed in the last section.

  12. Does the volume of Internet searches using suicide-related search terms influence the suicide death rate: data from 2004 to 2009 in Japan.

    Cross-correlation was examined for the volume of suicide-related Internet searches and suicide death rate. Analysis of Google data and figures released by the Ministry of Health, Labour, and Welfare indicated that the volume of searches using the search terms jisatsu (suicide) and jisatsu houhou (suicide method) are not correlated with the suicide death rate. In addition, a rising suicide death rate might be related to the increase in suicide-related search activity (particularly utsu[depression]), but an increase in suicide-related search activity itself is not directly linked to the rise of suicide death rate.

  13. Precision and accuracy of decay constants and age standards

    40 years of round-robin experiments with age standards teach us that systematic errors must be present in at least N-1 labs if participants provide N mutually incompatible data. In EarthTime, the U-Pb community has produced and distributed synthetic solutions with full metrological traceability. Collector linearity is routinely calibrated under variable conditions (e.g. [1]). Instrumental mass fractionation is measured in-run with double spikes (e.g. 233U-236U). Parent-daughter ratios are metrologically traceable, so the full uncertainty budget of a U-Pb age should coincide with interlaboratory uncertainty. TIMS round-robin experiments indeed show a decrease of N towards the ideal value of 1. Comparing 235U-207Pb with 238U-206Pb ages (e.g. [2]) has resulted in a credible re-evaluation of the 235U decay constant, with lower uncertainty than gamma counting. U-Pb microbeam techniques reveal the link petrology-microtextures-microchemistry-isotope record but do not achieve the low uncertainty of TIMS. In the K-Ar community, N is large; interlaboratory bias is > 10 times self-assessed uncertainty. Systematic errors may have analytical and petrological reasons. Metrological traceability is not yet implemented (substantial advance may come from work in progress, e.g. [7]). One of the worst problems is collector stability and linearity. Using electron multipliers (EM) instead of Faraday buckets (FB) reduces both dynamic range and collector linearity. Mass spectrometer backgrounds are never zero; the extent as well as the predictability of their variability must be propagated into the uncertainty evaluation. The high isotope ratio of the atmospheric Ar requires a large dynamic range over which linearity must be demonstrated under all analytical conditions to correctly estimate mass fractionation. The only assessment of EM linearity in Ar analyses [3] points out many fundamental problems; the onus of proof is on every laboratory claiming low uncertainties. Finally, sample

    Background: Resting heart rate is linked to risk of coronary artery disease, stroke, sudden death and noncardiovascular diseases. We conducted a meta-analysis to assess these associations in general populations and in populations of patients with hypertension or diabetes mellitus. Methods: We searched PubMed, Embase and MEDLINE from inception to Mar. 5, 2016. We used a random-effects model to combine study-specific relative risks (RRs). We used restricted cubic splines to assess the dose–response relation. Results: We included 45 nonrandomized prospective cohort studies in the meta-analysis. The multivariable adjusted RR with an increment of 10 beats/min in resting heart rate was 1.12 (95% confidence interval [CI] 1.09–1.14) for coronary artery disease, 1.05 (95% CI 1.01–1.08) for stroke, 1.12 (95% CI 1.02–1.24) for sudden death, 1.16 (95% CI 1.12–1.21) for noncardiovascular diseases, 1.09 (95% CI 1.06–1.12) for all types of cancer and 1.25 (95% CI 1.17–1.34) for noncardiovascular diseases excluding cancer. All of these relations were linear. In an analysis by category of resting heart rate (< 60 [reference], 60–70, 70–80 and > 80 beats/min), the RRs were 0.99 (95% CI 0.93–1.04), 1.08 (95% CI 1.01–1.16) and 1.30 (95% CI 1.19–1.43), respectively, for coronary artery disease; 1.08 (95% CI 0.98–1.19), 1.11 (95% CI 0.98–1.25) and 1.08 (95% CI 0.93–1.25), respectively, for stroke; and 1.17 (95% CI 0.94–1.46), 1.31 (95% CI 1.12–1.54) and 1.57 (95% CI 1.39–1.77), respectively, for noncardiovascular diseases. After excluding studies involving patients with hypertension or diabetes, we obtained similar results for coronary artery disease, stroke and noncardiovascular diseases, but found no association with sudden death. Interpretation: Resting heart rate was an independent predictor of coronary artery disease, stroke, sudden death and noncardiovascular diseases over all of the studies combined. When the analysis included only studies

    Tropical storms, such as cyclones, hurricanes and typhoons, present major threats to coastal communities. Around two million people worldwide have died and millions have been injured over the past two centuries as a result of tropical storms. Bangladesh is especially vulnerable to tropical cyclones, with around 718 000 deaths from them in the past 50 years. However, cyclone-related mortality in Bangladesh has declined by more than 100-fold over the past 40 years, from 500 000 deaths in 1970 to 4234 in 2007. The main factors responsible for these reduced fatalities and injuries are improved defensive measures, including early warning systems, cyclone shelters, evacuation plans, coastal embankments, reforestation schemes and increased awareness and communication. Although warning systems have been improved, evacuation before a cyclone remains a challenge, with major problems caused by illiteracy, lack of awareness and poor communication. Despite the potential risks of climate change and tropical storms, little empirical knowledge exists on how to develop effective strategies to reduce or mitigate the effects of cyclones. This paper summarizes the most recent data and outlines the strategy adopted in Bangladesh. It offers guidance on how similar strategies can be adopted by other countries vulnerable to tropical storms. Further research is needed to enable countries to limit the risks that cyclones present to public health. PMID:22423166

    The information about lightning activity is fundamental to atmospheric surveillance due its relevant applications on different aspects as security, defense, early warning system and for generation of statistical data for planning infrastructure projects. Few countries in the world have its own lightning detection networks which allow monitoring the lightning activity inside its national border. The development of the World Wide Lightning Location Network (WWLLN) provides a confidence global lightning data with low cost, which was already used to characterize the lightning activity in several regions of the world. The aim of the present work is the use of the lightning data obtained by the WWLLN to make an analysis on the lightning activity over Argentina between the years 2005-2012. In order to achieve this objective the isoceraunic maps of Argentina were made. These maps will be incorporated to the standard IRAM 2184-11 "lightning protection". Furthermore, by using data of flash per km2 per year, we provide a model for estimating deaths from lightning. The model is based on the parameterizations of the flash density, population density and urbanization of a given region. The model was adapted for Argentina and Brazil in order to obtain an estimation of deaths in different regions. The results obtained allows to promote protective behaviors in the population.

    OBJECTIVES: To evaluate the efficacy of the combination of annual screening with mammography, physical examination of the breasts and the teaching of breast self-examination in reducing the rate of death from breast cancer among women aged 40 to 49 years on entry. DESIGN: Individually randomized controlled trial. SETTING: Fifteen urban centres in Canada with expertise in the diagnosis and treatment of breast cancer. PARTICIPANTS: Women with no history of breast cancer and no mammography in the previous 12 months were randomly assigned to undergo either annual mammography and physical examination (MP group) or usual care after an initial physical examination (UC group). The 50,430 women enrolled from January 1980 through March 1985 were followed for a mean of 8.5 years. DATA COLLECTION: Derived from the participants by initial and annual self-administered questionnaires, from the screening examinations, from the patients' physicians, from the provincial cancer registries and by record linkage to the Canadian National Mortality Data Base. Expert panels evaluated histologic and death data. MAIN OUTCOME MEASURES: Rates of referral from screening, rates of detection of breast cancer from screening and from community care, nodal status, tumour size, and rates of death from all causes and from breast cancer. RESULTS: Over 90% of the women in each group attended the screening sessions or returned the annual questionnaires, or both, over years 2 to 5. The characteristics of the women in the two groups were similar. Compared with the Canadian population, the participants were more likely to be married, have fewer children, have more education, be in a professional occupation, smoke less and have been born in North America.

    The age-adjusted death rate for females aged 15-44 years was 5% lower in 2014 (82.1 per 100,000 population) than in 1999 (86.5). Among the five leading causes of death, the age-adjusted rates of three were lower in 2014 than in 1999: cancer (from 19.6 to 15.3, a 22% decline), heart disease (8.9 to 8.2, an 8% decline), and homicide (4.2 to 2.8, a 33% decline). The age-adjusted death rates for two of the five causes were higher in 2014 than in 1999: unintentional injuries (from 17.0 to 20.1, an 18% increase) and suicide (4.8 to 6.5, a 35% increase). Unintentional injuries replaced cancer as the leading cause of death in this demographic group. PMID:27362608

    OBJECTIVE: To evaluate the efficacy of annual mammography over and above annual physical examination of the breasts and the teaching of breast self-examination among women aged 50 to 59 on entry. DESIGN: Individually randomized controlled trial. SETTING: Fifteen urban centres in Canada with expertise in the diagnosis and treatment of breast cancer. PARTICIPANTS: Women with no history of breast cancer and no mammography in the previous 12 months were randomly assigned to undergo either annual mammography and physical examination (MP group) or annual physical examination only (PO group). The 39,405 women enrolled from January 1980 through March 1985 were followed for a mean of 8.3 years. DATA COLLECTION: Derived from the participants by initial and annual self-administered questionnaires, from the screening examinations, from the patients' physicians, from the provincial cancer registries and by record linkage to the Canadian National Mortality Data Base. Expert panels evaluated histologic and death data. MAIN OUTCOME MEASURES: Rates of referral from screening, rates of detection of breast cancer from screening and from community care, nodal status, tumour size and rates of death from all causes and from breast cancer. RESULTS: Over 85% of the women in each group attended the screening sessions after screen 1. The characteristics of the women in the two groups were similar. Compared with the Canadian population the participants were more likely to be married, have fewer children, have more education, be in a professional occupation, smoke less and have been born in North America. The rate of screen-detected breast cancer on first examination was 7.20 per 1000 in the MP group and 3.45 per 1000 in the PO group, more node-positive tumours were found in the MP group than in the PO group. At subsequent screens the detection rates were a little less than half the rates at screen 1. During years 2 through 5 the ratios of observed to expected cases of invasive breast cancer

    Delay of the diagnosis of hepatitis C virus (HCV), and its treatment to avert cirrhosis, is often present sincethe early stage of HCV progression is latent. Current methods to determine the incubation time to HCV-related cirrhosis and the duration time from cirrhosis to subsequent events (e.g. complications or death) used to be based on the time of liver biopsy diagnosis and ignore this delay which led to an interval censoring for the first event time and a double censoring for the subsequent event time. To investigate the impact of this delay in estimating HCV progression rates and relevant estimating bias, we present a correlated two-stage progression model for delayed diagnosis time and fit the developed model to the previously studied hepatitis C cohort data from Edinburgh. Our analysis shows that taking the delayed diagnosis into account gives a mildly different estimate of progression rate to cirrhosis and significantly lower estimated progression rate to HCV-related death in comparison with conventional modelling. We also find that when the delay increases, the bias in estimating progression increases significantly.

    In 1971 and 1973, Yoshida, et al. reported a higher relative risk of urinary bladder cancer among the workers of dyeing factories in Kyoto city. In order to confirm this, death certificates in Kyoto city from 1969 to 1972 were retrospectively investigated. Kyoto city was devided into three areas, that is, areas with high, medium and low clusterings of dyeing factories, and the differences of the mortality rates of all causes of deaths among these three areas were examined. As a result of this study, a statistically significant difference of the mortality rate of bladder cancer could not be found for males. But, the relative risk of bladder cancer in the areas with high and medium clusterings of dyeing factories compared to the area with low was found to be 1.45. Therefore, the relationship between dyeing work and bladder cancer could not necessarily be denied. It is, thus, necessary to carry out a prospective study, by which a more precise result can be obtained. In addition, our study revealed a significantly high mortality rate of skin cancer among the areas with high and medium clusterings of dyeing factories for males, observing a relative risk of 3.88. The observed association between skin cancer and dyeing work should be further studied.

    Starling national statistics indicate that New Haven, CT, is the seventh poorest city of its size, in terms of per capita income, in the United States. In 1989, it was reported to have the highest rate of infant mortality--18.5 infant deaths per 1,000 live birth--in the nation for a city with more than 100,000 people. Seventy-five percent of all perinatal deaths are attributed to low birth weight infants. Adequate prenatal care is a proven means of reducing this risk. To further compound the problem, substance abuse among pregnant women has increased dramatically. Census tract data revealed that many of the infant deaths were localized to several well-defined areas of the city. Forty-four percent of the infant deaths were ascribed to extreme immaturity or other causes related to low birth weight. Approximately 21 percent of the pregnant population had either no prenatal care or care was begun late--after the first trimester. The traditional avenues for prenatal care have been ineffective; an innovative approach, one that can be replicated, was initiated. The Hospital of Saint Raphael's "Project MotherCare" embarked on an initiative to address these problems by reducing the access barriers to prenatal care regardless of insurance status or ability to pay. The mission was twofold: (a) to bring prenatal care to underserved neighborhoods of New Haven and (b) to identify the substance-abusing pregnant woman and deliver a continuum of services including prenatal care, counseling, social services, and referral to a drug treatment program.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7938385

    Debris flows from the steep, granitic hillslopes of the Kingston Range, CA are commensurate in age with nearby fluvial deposits. Quaternary chronostratigraphic differentiation of debris-flow deposits is based upon time-dependent characteristics such as relative boulder strength, derived from Schmidt Hammer measurements, degree of surface desert varnish, pedogenesis, and vertical separation. Rock strength is highest for Holocene-aged boulders and decreases for Pleistocene-aged boulders weathering to grus. Volumes of age-stratified debris-flow deposits, constrained by deposit thickness above bedrock, GPS surveys, and geologic mapping, are greatest for Pleistocene deposits. Shallow landslide susceptibility, derived from a topographically based GIS model, in conjunction with deposit volumes produces watershed-scale erosion rates of ???2-47 mm ka-1, with time-averaged Holocene rates exceeding Pleistocene rates. ?? 2003 Millpress.

    Evidence linking air pollution with adverse cardiopulmonary outcomes is accumulating. However, few studies have been conducted to evaluate whether vehicle emission control improves public health. We thus evaluated the effect of a diesel emission control law on mortality rates in 23 wards of Tokyo metropolitan area, Japan. We obtained daily counts of mortality and concentrations of nitrogen dioxide (NO(2)) and particulate matter less than 2.5 μm in diameter (PM(2.5)) from April 2003 to December 2008. Time-series and interrupted time-series analysis were employed to analyze the data in two periods: prior to the introduction of tighter restrictions (April 2003 to March 2006) and after the enforcement (April 2006 to December 2008). Concentrations of air pollutants gradually decreased during the study period: from 36.3 ppb (NO(2)) and 22.8 μg/m(3) (PM(2.5)) to 32.1 ppb and 20.3 μg/m(3), respectively. Air pollutants were positively associated with circulatory and pulmonary disease mortality, especially cerebrovascular disease. Each same-day PM(2.5) increase of 10 μg/m(3) was associated with a 1.3% increase in cerebrovascular mortality rate (95% confidence interval: 0.2-2.4). Rate ratios were attenuated after the enforcement in most of the outcomes, probably due to reduced toxicity of the pollutants. In the crude interrupted time-series analysis, reductions of standardized mortality rates after the enforcement were the greatest in high traffic areas. Even after adjustment of longer-time trend, mortality rate from cerebrovascular disease was reduced by 8.50% (p<.001) with dose-response relationship. However, the declines in other cause-specific mortality became equivocal. This natural experiment in Tokyo suggests that emission controls improved air quality. Although suggestive, further data are needed to conclusively demonstrate an impact on mortality rates.

    The autoimmune diseases are among the 10 leading causes of death for women and the number two cause of chronic illness in America as well as a predisposing factor for cardiovascular diseases and cancer. Patients of some autoimmune diseases have shown a shorter life span and are a model of accelerated immunosenescence. Conversely, centenarians are used as a model of successful aging and have shown several immune parameters that are better preserved and lower levels of autoantibodies. The study reported here focused on clarifying the connection between longevity and some autoimmune and allergic diseases in 29 developed Organisation for Economic Co-operation and Development (OECD) countries, because multidisciplinary analyses of the accelerated or delayed aging data could show a distinct relationship pattern, help to identify common factors, and determine new important factors that contribute to longevity and healthy aging. The relationships between the mortality rates data of multiple sclerosis (MS), rheumatoid arthritis (RA), asthma, the incidence of type 1 diabetes (T1D) from one side and centenarian rates (two sets) as well as life expectancy data from the other side were assessed using regression models and Pearson correlation coefficients. The data obtained correspond to an inverse linear correlation with different degrees of linearity. This is the first observation of a clear tendency of diminishing centenarian rates or life expectancy in countries having higher death rates of asthma, MS, and RA and a higher incidence of T1D in children. The conclusion is that most probably there are common mechanistic pathways and factors affecting the above diseases and at the same time but in the opposite direction the processes of longevity.

    The reliability of the afterhyperpolarization (AHP) time course, as estimated by the interval death rate (IDR) analysis was evaluated both within and between investigators. The IDR analysis uses the firing history of a single motor unit train at low tonic firing rates to calculate an estimate of the AHP time course [Matthews PB. Relationship of firing intervals of human motor units to the trajectory of post-spike after-hyperpolarization and synaptic noise. J Physiol 1996;492:597-628]. Single motor unit trains were collected from the tibialis anterior (TA) to determine intra-rater reliability (within investigator). Data from the first dorsal interosseus (FDI), collected in a previous investigation [Gossen ER, Ivanova TD, Garland SJ. The time course of the motoneurone afterhyperpolarization is related to motor unit twitch speed in human skeletal muscle. J Physiol 2003;552:657-64], were used to examine the inter-rater reliability (between investigators). The lead author was blinded to the original time constants and file identities for the re-analysis. The intra-rater reliability of the AHP time constant in the TA data was high (r(2)=0.88; p<0.001; ICC=0.91). The inter-rater reliability for the FDI data was also strong (r(2)=0.92; p<0.001; ICC=0.95). The standard error of measurement was 0.61 ms for the TA and 0.55 ms for FDI. It is concluded that the interval death rate analysis is a reliable tool for estimating the AHP time course with experienced investigators.

    Severe premature babies present a risk profile higher than the normal population. Reasons are related to the incomplete development of physiological systems that support baby's life. Heart Rate Variability (HRV) analysis can help the identification of distress conditions as it is sensitive to Autonomic Nervous System (ANS) behavior. This paper presents results obtained in 35 babies with severe prematurity, in quiet and active sleep and in prone and supine position. HRV was analyzed in time and frequency domain and with nonlinear parameters. The novelty of this approach lies in the combined use of parameters generally adopted in fetal monitoring and "adult" indices. Results show that most parameters succeed in classifying different experimental conditions. This is very promising as our final objective is to identify a set of parameters that could be the basis for a risk classifier to improve the care path of premature population. PMID:25571458

    Epilepsy is associated with interictal and ictal autonomic dysfunction. Seizures can immediately cause increases in blood pressure (BP) and heart rate (HR). However, it is unknown whether uncontrolled seizures, particularly when frequent, might chronically elevate the BP or HR. Additionally, it is unknown whether the interictal BP and HR is altered in individuals who are at risk for SUDEP, compared with other individuals with epilepsy. SUDEP often occurs in patients with highly refractory epilepsy. Such individuals might be at risk for a state of chronically heightened sympathetic tone, which might affect the HR and BP interictally. This study compared the resting awake interictal HR and BP in individuals who subsequently died due to SUDEP and compared these to HR and BP in two control epilepsy groups (refractory and controlled). While the overall HR and BP are similar between groups, there is a trend toward a higher diastolic BP and more stable HR in individuals who subsequently died due to SUDEP, compared with epilepsy controls. These data suggest that there may be specific types of interictal autonomic dysfunction in individuals at risk for SUDEP. Such abnormalities might serve as markers for those at elevated risk for SUDEP. PMID:26921856

    The main objective of this study was to analyze the mortality trends of female breast cancer in Turkey between the years 1987-2008. The rates per 100,000 age-standardized to the European standard population were assessed and time trends presented using joinpoint regression analysis. Average annual percent change (AAPC), anual percent change (APC) and 95% confidence interval (CI) was calculated. Nearly 23,000 breast cancer deaths occurred in Turkey during the period 1987-2008, with the average annual age-standardized mortality rate (ASR) being 11.9 per 100,000 women. In the last five years, significant increases were observed in all age groups, but there was no significant change over the age of 65. In this period, the biggest significant increase was in the 45-54 age group (AAPC=4.3, 95%CI=2.6 to 6.0). PMID:25292030

    Mouse melanoma cells in a culture medium are treated using a nanosecond pulsed streamer discharge plasma and the correlations between the rate of cell death and the densities of reactive species (OH, O, and NO) in the plasma are measured. The plasma is irradiated onto the culture medium surface with a vertical gas flow of an O2/N2 mixture from a glass tube at various gas flow rates and O2 concentrations. The densities of the reactive species are measured very close to the culture medium surface, where the reactive species interact with the culture medium, using laser-induced fluorescence. In the case of the N2 discharge (O2 = 0%), an increase in gas flow rate decreases OH density because it lowers the water vapor concentration by diluting the vapor, which is required for OH production. The increase in gas flow rate also leads to a decreased cell death rate. In the case of the O2/N2 discharge, on the other hand, an increase in O2 concentration at a fixed flow rate does not affect the rate of cell death, although it considerably changes the O and NO densities. These findings indicate that some reactive species derived from water vapor such as OH are responsible for the melanoma cell death, whereas those from O2, such as O and NO, are less likely responsible. They also indicate the importance of water evaporation from the culture medium surface in cell treatment.

  1. Predation or scavenging? Thoracic muscle pH and rates of water loss reveal cause of death in arthropods.

    2010-08-01

    The difficulty of directly observing predatory events hinders a complete understanding of how predation structures food webs. Indirect approaches such as PCR-based and isotopic analyses clarify patterns of resource consumption but fail to distinguish predation from scavenging. Given that facultative scavenging is a ubiquitous and phylogenetically widespread foraging strategy, an improved ability to discriminate prey from carrion is needed to enhance an understanding of the demographic effects of consumption and the true nature of trophic interactions. Using physiological properties of muscle tissue - specifically pH and rate of water loss - we develop a novel method to discriminate prey from carrion collected by scavenging hymenopteran predators. Our focal system is the western yellowjacket (Vespula pensylvanica), a common scavenging predator in Hawaii and western North America. Prior to consumption, the physical properties of hymenopteran muscle tissue change in a quantifiable and deterministic manner post mortem and can be used to estimate the time and putative cause of death of diet items. Applying this method in laboratory and field situations resulted in the correct identification of prey and carrion in 49 out of 56 cases (88%). Although further investigation is needed to determine how post-mortem physiology of diet items changes in the guts of consumers, the approaches developed in this study can be used to distinguish predation from scavenging by central-place foragers (particularly arthropods). Such information will provide a more definitive characterization of species interactions and food webs.

    Morbidity and mortality from heart failure (HF) are high, and current risk stratification approaches for predicting HF progression are imperfect. Adenosine triphosphate (ATP) is required for normal cardiac contraction, and abnormalities in creatine kinase (CK) energy metabolism, the primary myocardial energy reserve reaction, have been observed in experimental and clinical HF. However, the prognostic value of abnormalities in ATP production rates through CK in human HF has not been investigated. Fifty-eight HF patients with nonischemic cardiomyopathy underwent ³¹P magnetic resonance spectroscopy (MRS) to quantify cardiac high-energy phosphates and the rate of ATP synthesis through CK (CK flux) and were prospectively followed for a median of 4.7 years. Multiple-event analysis (MEA) was performed for HF-related events including all-cause and cardiac death, HF hospitalization, cardiac transplantation, and ventricular-assist device placement. Among baseline demographic, clinical, and metabolic parameters, MEA identified four independent predictors of HF events: New York Heart Association (NYHA) class, left ventricular ejection fraction (LVEF), African-American race, and CK flux. Reduced myocardial CK flux was a significant predictor of HF outcomes, even after correction for NYHA class, LVEF, and race. For each increase in CK flux of 1 μmol g⁻¹ s⁻¹, risk of HF-related composite outcomes decreased by 32 to 39%. These findings suggest that reduced CK flux may be a potential HF treatment target. Newer imaging strategies, including noninvasive ³¹P MRS that detect altered ATP kinetics, could thus complement risk stratification in HF and add value in conditions involving other tissues with high energy demands, including skeletal muscle and brain.

    To evaluate the achievement of health care services in Korea independent of other socioeconomic factors, we observed the time trend of avoidable death between 1983 and 2004. A list of avoidable causes of death was constructed based on the European Community Atlas of "Avoidable Death". We calculated sex- and age-standardized mortality rates of Korean aged 1-64 yr using data of the Korea National Statistical Office. The avoidable mortality rate (per 100,000 persons) decreased from 225 to 84 in men and from 122 to 41 in women. Accordingly, the proportion of avoidable deaths among all classifiable deaths was reduced by 8.1% in men and 6.4% in women. However, mortality rates from some preventable causes such as ischemic heart disease and malignant neoplasms of lung, breast, cervix, and colorectum have been on the rise. Mortality preventable by appropriate medical care showed the greatest reduction (by 77.8%), while the mortality preventable by primary prevention showed the least reduction (by 50.0%). These findings suggest that health care service has significantly contributed to the improvement of health in Korea. However, more effective intervention programs would be needed given the less reduction in mortality avoidable by primary or secondary prevention than expected and unexpectedly increasing mortality from several preventable causes.

    Health professionals and educators should develop their abilities to educate about death and to comfort the bereaved. Due to lower death rates, the lack of philosophical religious views, and distorted perceptions of death contributed by television, death has become a mystery instead of a segment of the common experience.

    Bcl-2 has been demonstrated to inhibit apoptosis in breast cancer cells in vitro, and the ratio between Bcl-2 and its proapoptotic homologue Bax seems to be an important determinant of cellular sensitivity to induction of apoptosis. However, little information is available on the relationship between Bcl-2 and the rate of apoptotic and necrotic cell death in breast tumours. From a series of 441 premenopausal, lymphnode-negative breast cancer patients, a subset of 49 tumours was selected in which immunostaining for the 26-kDa isoform of Bcl-2 was either absent (n = 23) or very high (n = 26). High expression of Bcl-2 was found to be strongly associated with low rates of apoptotic (P < 0.001) and necrotic cell death (P < 0.001). The mean value of the apoptotic index was 2.69%+/-1.40% in Bcl-2-negative tumours and 0.68%+/-1.00% in Bcl-2-positive tumours. Expression of the proapoptotic protein Bax correlated neither with Bcl-2 nor with the frequency of apoptotic cells. Immunostaining for the antiapoptotic Bcl-2 homologue BcI-X(L) correlated with Bcl-2 expression (P < 0.001) but not with apoptosis. High proliferation rate and high tumour grade (Bloom-Richardson) were strongly associated with absence of Bcl-2 expression (P< 0.001). p53 accumulation was associated with absence of Bcl-2 expression and increased apoptotic activity. Loss of Bcl-2 expression was strongly correlated with increased apoptotic and necrotic cell death, high proliferation rate and high tumour grade, supporting a model in which Bcl-2 not only mediates cell death, but also cell division in breast cancer tissue, and in which regulation of cell division and cell death are tightly linked.

    Five samples were made available as standards for the 1984 Fission Track Workshop held in the summer of 1984 (Rensselaer Polytechnic Institute, Troy, New York). Two zircons, two apatites and a sphene were distributed prior to the meeting to 40 different laboratories. To date, 24 different analysts have reported results. The isotopic ages of the standards ranged from 16.8 to 98.7 Myr. Only the statement that the age of each sample was less than 200 Myr was provided with the set of standards distributed. Consequently, each laboratory was required to use their laboratory's accepted treatment (irradiation level, etching conditions, counting conditions, etc.) for these samples. The results show that some workers have serious problems in achieving accurate age determinations. This emphasizes the need to calibrate experimental techniques and counting procedures against age standards before unknown ages are determined. Any fission-track age determination published or submitted for publication can only be considered reliable if it is supported by evidence of consistent determinations on age standards. Only this can provide the scientific community with the background to build up confidence concerning the validity of the fission-track method. ?? 1985.

    Introduction The suicide rate of South Korea has increased dramatically during the past decades, as opposed to steadily decreasing trends in Japan and Hong Kong. Although the recent increase of suicide in South Korea may be related to changing socioeconomic conditions and other contextual factors, it may also reflect, in part, a reduction of misidentified suicide cases due to improving classification of manner of death. Method We compared the annual proportional change of suicide, undetermined death, and accidental death from South Korea with those of Japan and Hong Kong from 1992 to 2011; a greater proportional change of the manner-of-death categories during the period is indicative of a relatively less stable registration and hence a greater potential for misclassification bias on reported suicide trends. Subgroup analyses stratifying the deaths by methods were also conducted. To estimate the impact, the age-standardized rates of these three death categories in each site were calculated. Results We found that, during the 20-year observation period, the proportional change of suicide, undetermined death, and accidental death in South Korea was significantly greater than Japan and Hong Kong. Similar observations were made in subgroup analyses. While death rates of the three manners in Japan and Hong Kong generally moved in a parallel fashion, the increase of suicide in South Korea occurred concomitantly with a significant reduction of its accidental death rate. 43% of the increase in suicides could be attributed to the decrease in accidental deaths, while 57% of the increase could be due to fundamental causes. Conclusion Our data suggest that, during the mid-1990s and after, the increasing burden of suicide in South Korea initially was masked, in part, by misclassification. Thus, the later apparently rapid increase of suicides reflected steadily improving classification of manner of death, as well as a more fundamental increase in the suicide rate. PMID:25992879

    Objectives Healthcare providers in low-resource settings confront high rates of perinatal mortality. How providers cope with such challenges can affect their well-being and patient care; we therefore sought to understand how physicians and midwives make sense of and cope with these deaths. Methods We conducted semi-structured interviews with midwives, obstetrician-gynecologists, pediatricians and trainee physicians at a large teaching hospital in Kumasi, Ghana. Interviews focused on participants' coping strategies surrounding perinatal death. We identified themes from interview transcripts using qualitative content analysis. Results Thirty-six participants completed the study. Themes from the transcripts revealed a continuum of control/self-efficacy and engagement with the deaths. Providers demonstrated a commitment to push on with their work and provide the best care possible. In select cases, they described the transformative power of attitude and sought to be agents of change. Conclusions Physicians and midwives in a low-resource country in sub-Saharan Africa showed remarkable resiliency in coping with perinatal death. Still, future work should focus on training clinicians in coping and strengthening their self-efficacy and engagement. PMID:26987854

    Our aim was to evaluate the effects of fish oil feeding on sperm classical parameters, level of reactive oxygen spices (ROS), spermatozoa death incidence and in vitro fertilization (IVF) rate in rams. We randomly assigned nine rams, into two experimental groups (isoenergetic and isonitrogenous rations with constant level of vitamin E supplement): control (CTR; n = 5) and fish oil (FO; n = 4, 35 g/day/ram). Diets were fed for 70 days during the physiological breeding season. After a 21-day dietary adaptation period, semen was collected weekly from each ram by an artificial vagina. Sperm classical parameters were determined by the computer-assisted sperm analyzer system (CASA), and it was prepared for IVF process by swim-up technique. These evaluations were performed during the first and last weeks of sampling. Intracellular ROS level and spermatozoa death incidence were detected by flow cytometry on a weekly basis after adaptation. Data were analysed with SPSS 15. The volume, concentration (3.6 and 2.7 × 10(9) /ml) and sperm progressive motility (60 and 48%) were significantly improved in the FO group compared with the CTR (p < 0.05). A comparison of two-cell stage embryos following IVF in the two groups showed a significantly higher fertilization rate in the FO group (56%) compared with the CTR (49%). Superoxide anion (O2 (-) ) rate was significantly lower (p < 0.05) at the third week of sampling in the FO. Although the H2 O2 rate was numerically lower in the FO group compared with the CTR, this difference was not significant. In addition, apoptosis showed a significant difference in the third week of sampling (15 and 30% for FO and CTR, respectively; p < 0.05). Overall, adding fish oil to the ram diet not only improved sperm quality and IVF results, it also could reduce oxygen-free radicals and the incidence of spermatozoa death.

    This study investigated the relationship between positive/negative death imagery and death anxiety. Subjects were 179 undergraduate students at a large, private, midwestern university. Results reveal that on five measures of death anxiety the subjects with low death anxiety scores had significantly more positive death images than did those with high death anxiety scores. The few subjects who imagined death to be young (N = 14) had a significantly more positive image of death than those who perceived it to be an old person. Death was seen as male by 92% of the male respondents and 74% of the female respondents. Significant differences in death imagery and death anxiety were found between subjects enrolled in an introductory psychology course and those enrolled in a thanatology course. No sex differences in death anxiety or positive/negative death imagery were found.

    OBJECTIVES: This study sought to determine whether nutrient-rich whole grains reduce mortality risk. METHODS: The study included 38,740 Iowa women, aged 55 to 69 years. A food frequency questionnaire was used to obtain data on grain intake. RESULTS: Median whole grain intake quintiles ranged from a median of 0.2 to more than 3 servings per day. Women with higher intakes had healthier lifestyles and less baseline disease. The total death rate decreased in increasing quintiles, and the pattern repeated for cancer, cardiovascular disease, and other causes combined. Adjusted for lifestyle and baseline disease, the relative hazard rate ratio for total death was about 0.85 in daily consumers of whole grain. Findings persisted in strata of baseline healthy and diseased and were not explained by dietary fiber. Rates of total mortality, but not cardiovascular disease mortality, were higher among frequent consumers of refined grain. CONCLUSIONS: Total mortality risk was inversely associated with whole grain intake and positively associated with refined grain intake. Refined grains contributed more than 20% of energy intake, and whole grains contributed 1%. Substitution of whole for refined grain may reduce chronic disease risk in the United States.

    US infant death rates for 1960 to 1980 declined most quickly in (1) 1970 to 1973 in states that legalized abortion in 1970, especially for infants in the lowest 3 income quintiles (annual percentage change = −11.6; 95% confidence interval = −18.7, −3.8), and (2) the mid-to-late 1960s, also in low-income quintiles, for both Black and White infants, albeit unrelated to abortion laws. These results imply that research is warranted on whether currently rising restrictions on abortions may be affecting infant mortality. PMID:25713932

    Some conservative groups argue that allowing same-sex couples to marry reduces the value of marriage to opposite-sex couples. This article examines how changes in U.S. legal recognition laws occurring between 1995 and 2010 designed to include same-sex couples have altered marriage rates in the United States. Using a difference-in-differences strategy that compares how marriage rates change after legal recognition in U.S. states that alter legal recognition versus states that do not, I find no evidence that allowing same-sex couples to marry reduces the opposite-sex marriage rate. Although the opposite-sex marriage rate is unaffected by same-sex couples marrying, it decreases when domestic partnerships are available to opposite-sex couples.

    We studied the relations between the time history of smooth muscle cells (SMCs) death rate and heating condition in vitro to clarify cell death mechanism in heating angioplasty, in particular under the condition in which intimal hyperplasia growth had been prevented in vivo swine experiment. A flow heating system on the microscope stage was used for the SMCs death rate measurement during or after the heating. The cells were loaded step-heating by heated flow using a heater equipped in a Photo-thermo dynamic balloon. The heating temperature was set to 37, 50-60°C. The SMCs death rate was calculated by a division of PI stained cell number by Hoechst33342 stained cell number. The SMCs death rate increased 5-10% linearly during 20 s with the heating. The SMCs death rate increased with duration up to 15 min after 5 s heating. Because fragmented nuclei were observed from approximately 5 min after the heating, we defined that acute necrosis and late necrosis were corresponded to within 5 min after the heating and over 5 min after the heating, respectively. This late necrosis is probably corresponding to apoptosis. The ratio of necrotic interaction divided the acute necrosis rate by the late necrosis was calculated based on this consideration as 1.3 under the particular condition in which intimal hyperplasia growth was prevented in vivo previous porcine experiment. We think that necrotic interaction rate is larger than expected rate to obtain intimal hyperplasia suppression.

    Many candidates for lung transplantation (LT) die on the waiting list, raising the question of graft availability and strategy for organ allocation. We report the experience of the new organ allocation program, "High Emergency Lung Transplantation" (HELT), since its implementation in our center in 2007. Retrospective analysis of 201 lung transplant patients, of whom 37 received HELT from 1st July 2007 to 31th May 2012. HELT candidates had a higher impairment grade on respiratory status and higher Lung Allocation Score (LAS). HELT patients had increased incidence of perioperative complications (e.g., perioperative bleeding) and extracorporeal circulatory assistance (75% vs. 36.6%, P = 0.0005). No significant difference was observed between HELT and non-HELT patients in mechanical ventilation duration (15.5 days vs. 11 days, P = 0.27), intensive care unit length of stay (15 days vs. 10 days, P = 0.22) or survival rate at 12 (81% vs. 80%), and 24 months post-LT (72.9% vs. 75.0%). Lastly, mortality on the waiting list was spectacularly reduced from 19% to 2% when compared to the non-HELT 2004-2007 group. Despite a more severe clinical status of patients on the waiting list, HELT provided similar results to conventional LT. These results were associated with a dramatic reduction in the mortality rate of patients on the waiting list.

    Cross-sectional data from Phase 1 of the Canadian Study of Health and Aging was used to examine the relationship between two self-report health measures: "How would you say your health is these days?"(HEALTH) and "How much do your health troubles stand in the way of your doing the things you want to do?"(TROUBLE). The contribution of these measures to predictive models for institutionalization and mortality is examined, using linked data from Phases 1 and 2. Their relationship to a proposed frailty measure is also examined. At CSHA-1, a majority of respondents perceived that they were in good health and did not feel that their health problems interfered with their preferred activities. At all frailty levels, a majority of both males and females rated their health as "very good" or "pretty good." As frailty increased, health problems increasingly interfered with normal activities. Logistic regression of the longitudinal data indicated that, despite their correlation, HEALTH and TROUBLE cannot act as proxies for each other. They appear to predict independently; adding one to the other significantly improved prediction of institutionalization and mortality. PMID:11892970

    In nematodes, environmental or physiological perturbations alter death’s scaling of time. In human cancer, genetic perturbations alter death’s curvature of time. Those changes in scale and curvature follow the constraining contours of death’s invariant geometry. I show that the constraints arise from a fundamental extension to the theories of randomness, invariance and scale. A generalized Gompertz law follows. The constraints imposed by the invariant Gompertz geometry explain the tendency of perturbations to stretch or bend death’s scaling of time. Variability in death rate arises from a combination of constraining universal laws and particular biological processes. PMID:27785361

    This study aimed to analyze trends in the 10 leading causes of death in Korea from 1983 to 2012. Death rates were derived from the Korean Statistics Information Service database and age-adjusted to the 2010 population. Joinpoint regression analysis was used to identify the points when statistically significant changes occurred in the trends. Between 1983 and 2012, the age-standardized death rate (ASR) from all causes decreased by 61.6% for men and 51.2% for women. ASRs from malignant neoplasms, diabetes mellitus, and transport accidents increased initially before decreasing. ASRs from hypertensive diseases, heart diseases, cerebrovascular diseases and diseases of the liver showed favorable trends (ASR % change: -94.4%, -53.8%, -76.0%, and -78.9% for men, and -77.1%, -36.5%, -67.8%, and -79.9% for women, respectively). ASRs from pneumonia decreased until the mid-1990s and thereafter increased. ASRs from intentional self-harm increased persistently since around 1990 (ASR % change: 122.0% for men and 217.4% for women). In conclusion, death rates from all causes in Korea decreased significantly in the last three decades except in the late 1990s. Despite the great strides made in the overall mortality, temporal trends varied widely by cause. Mortality trends for malignant neoplasms, diabetes mellitus, pneumonia and intentional self-harm were unfavorable.

    Due to the large size (e.g. sections of tree trunks) and highly heterogeneous spatial distribution of deadwood, the timescales involved in the coarse woody debris (CWD) decay of Picea abies (L.) Karst. and Larix decidua Mill. in Alpine forests are largely unknown. We investigated the CWD decay dynamics in an Alpine valley in Italy using the chronosequence approach and the five-decay class system that is based on a macromorphological assessment. For the decay classes 1-3, most of the dendrochronological samples were cross-dated to assess the time that had elapsed since tree death, but for decay classes 4 and 5 (poorly preserved tree rings) radiocarbon dating was used. In addition, density, cellulose, and lignin data were measured for the dated CWD. The decay rate constants for spruce and larch were estimated on the basis of the density loss using a single negative exponential model, a regression approach, and the stage-based matrix model. In the decay classes 1-3, the ages of the CWD were similar and varied between 1 and 54 years for spruce and 3 and 40 years for larch, with no significant differences between the classes; classes 1-3 are therefore not indicative of deadwood age. This seems to be due to a time lag between the death of a standing tree and its contact with the soil. We found distinct tree-species-specific differences in decay classes 4 and 5, with larch CWD reaching an average age of 210 years in class 5 and spruce only 77 years. The mean CWD rate constants were estimated to be in the range 0.018 to 0.022 y-1 for spruce and to about 0.012 y-1 for larch. Snapshot sampling (chronosequences) may overestimate the age and mean residence time of CWD. No sampling bias was, however, detectable using the stage-based matrix model. Cellulose and lignin time trends could be derived on the basis of the ages of the CWD. The half-lives for cellulose were 21 years for spruce and 50 years for larch. The half-life of lignin is considerably higher and may be more than

    Background Acute myeloid leukemia (AML) is a disease with marked heterogeneity. Despite major improvement in outcome, it remains a life-threatening malignancy. Demographic and clinical data on pediatric AML is lacking among the Lebanese population. Purpose We aimed to identify clinical, molecular and outcome data in children with AML in Lebanon. Methods A retrospective chart review of children with AML diagnosed in three Lebanese hospitals during the past 8 years was conducted. Results From May 2002 through March 2010, we identified 24 children with AML in Saint George Hospital University Medical Center, University Medical Center Rizk Hospital, and Abou-Jaoude Hospital. Males and females were equally represented; median age at diagnosis was 9 years (range 1–24) and median WBC at diagnosis was 31 × 109/L (range: 2.1–376 × 109/L). Twenty five percent of patients (6 out of 24) had acute promyelocytic leukemia (APL). Karyotype was normal in 33% of patients; t(8;21), inv (16), t(8;9), t(7;11), t(9;11), complex chromosomal abnormality, monosomy 7 and trisomy 8 were the most common cytogenetic abnormalities encountered. Patients were treated on different European and North American protocols. Twelve patients (50%) achieved morphologic CR after cycle 1, 6 of them (50%) had bone marrow relapse within 11 months from diagnosis. Nine patients underwent allogeneic stem cell transplant, and 3 of them are alive at 5 years post-transplant. Early death rate was 16.6% of patients, mainly those with APL and a presenting WBC > 10 × 109/L. Fifty per cent of APL patients had an early death due to DIC despite starting ATRA therapy. Overall, median survival for AML patients who died from disease progression was 25.8 months (range: 1–60 months). Overall disease-free survival was 30.4%. Patients < 10 years of age had a 50% survival rate compared to 0% in patients > 10 years. Conclusions Our report highlights the needs in Lebanon for better supportive care of children with APL

    The physiological role of B cell lymphoma 2 (Bcl-2) homology 3–only proteins has been investigated in mice lacking the individual genes identifying rate-limiting roles for Bim (Bcl-2–interacting mediator of cell death) and Puma (p53–up-regulated modulator of apoptosis) in apoptosis induction. The loss of Bim protects lymphocytes from apoptosis induced by cytokine deprivation and deregulated Ca++ flux and interferes with the deletion of autoreactive lymphocytes and the shutdown of immune responses. In contrast, Puma is considered the key mediator of p53-induced apoptosis. To investigate the hypothesis that Bim and Puma have overlapping functions, we generated mice lacking both genes and found that bim−/−/puma−/− animals develop multiple postnatal defects that are not observed in the single knockout mice. Most strikingly, hyperplasia of lymphatic organs is comparable with that observed in mice overexpressing Bcl-2 in all hemopoietic cells exceeding the hyperplasia observed in bim−/− mice. Bim and Puma also have clearly overlapping functions in p53-dependent and -independent apoptosis. Their combined loss promotes spontaneous tumorigenesis, causing the malignancies observed in Bcl-2 transgenic mice, but does not exacerbate the autoimmunity observed in the absence of Bim.

    Due to the large size and highly heterogeneous spatial distribution of deadwood, the time scales involved in the coarse woody debris (CWD) decay of Picea abies (L.) Karst. and Larix decidua Mill. in Alpine forests have been poorly investigated and are largely unknown. We investigated the CWD decay dynamics in an Alpine valley in Italy using the five-decay class system commonly employed for forest surveys, based on a macromorphological and visual assessment. For the decay classes 1 to 3, most of the dendrochronological samples were cross-dated to assess the time that had elapsed since tree death, but for decay classes 4 and 5 (poorly preserved tree rings) and some others not having enough tree rings, radiocarbon dating was used. In addition, density, cellulose and lignin data were measured for the dated CWD. The decay rate constants for spruce and larch were estimated on the basis of the density loss using a single negative exponential model. In the decay classes 1 to 3, the ages of the CWD were similar varying between 1 and 54 years for spruce and 3 and 40 years for larch with no significant differences between the classes; classes 1-3 are therefore not indicative for deadwood age. We found, however, distinct tree species-specific differences in decay classes 4 and 5, with larch CWD reaching an average age of 210 years in class 5 and spruce only 77 years. The mean CWD rate constants were 0.012 to 0.018 yr-1 for spruce and 0.005 to 0.012 yr-1 for larch. Cellulose and lignin time trends half-lives (using a multiple-exponential model) could be derived on the basis of the ages of the CWD. The half-lives for cellulose were 21 yr for spruce and 50 yr for larch. The half-life of lignin is considerably higher and may be more than 100 years in larch CWD.

    This study estimated the number of years of life lost (YLL) by cause due to premature death in Tunisia for the year 2006. We adopted the methodology (SEYLL) proposed by Murray and Lopez. The crude rate of YLL was 58.1 per 1000 inhabitants. After age-standardization using the world population, we obtained a rate of 57.7 YLL per 1000. Cardiovascular diseases (CVD) (19.3% of total YLL) and cancers (17.8%) dominated the burden of premature mortality, followed by perinatal conditions (13.6%). Excluding extreme age groups where perinatal conditions (0-4 years) and CVD (> 60 years) dominated the YLL's causes, injuries (road traffic crashes, falls, etc.) and cancers were most responsible for YLL. The present study highlights the major contribution of noncommunicable diseases to YLL in Tunisia. The promotion of healthy lifestyle and the reinforcement of secondary prevention in primary health care are the best ways to tackle these diseases.

    Introduction Cardiovascular diseases are increasing in aging HIV-positive patients (HIV+). Impact of traditional cardiovascular risk factors, HIV-specific parameters and antiretroviral therapy (ART) on the incidence of cardiovascular events (CVE) and on the mortality rate are investigated in different HIV+ cohorts. Methods The HIV HEART (HIVH) study is an ongoing prospective observational cohort study in the German Ruhr area to assess the frequency and clinical course of cardiac disorders in 1481 HIV+ by standardized non-invasive cardiovascular screening. CVE were defined as diagnosed or documented myocardial infarction, coronary heart disease, arterial coronary intervention, stent implantation, bypass operation and stroke. Results 1481 HIV+ subjects (mean age: 49.3±10.7 years (y), female: 15.6%) were included. 130 CVE and 90 deaths were documented until the end of 7, 5 year follow-up of HIVH. Mean duration of the HIV-infection was 12.9±6.8 y. HIV+ were treated with ART on average for 8.6±6.8 y. According to the CDC classification of the HIV-infection, HIV+ were distributed over the clinical categories (A:34.6%; B:31.4% and C:33.9%) while more than the half had an advanced immunodeficiency (I:8.3%; II:41.1%; III:50.7%). Advanced clinical and immunological stages were significantly (p<0.001) associated with higher incidences of deaths (A:16.7%; B:26.7%; C:56.7% and I:6.7%; II:27.7%; III:65.6%) and CVE (A:17.7%; B:33.1%; C:49.2% and I:3.1%; II:32.3%; III:64.6%) but not with the duration of HIV-infection (per y: Hazard ratio (HR): 0.91 [0.88–0.94]) and ART (per y: HR: 0.81 [0.79–0.84]) adjusted for age. The proportion of deceased HIV+ with HIV-RNA ≥50 copies/mL and lower CD4-cell counts at their last visit is significantly higher compared with living HIV+ without CVE (HIV-RNA ≥50 copies/mL: 25.6% vs 14.7%). Median CD4-cells: 286.5 cells/µL (IQR: 168.8–482.8) versus 574 cells/µL (IQR: 406–786). 96.1% of the living HIV+ with CVE had HIV-RNA<50 copies

    PROBLEM BEING ADDRESSED Family physicians are often called upon to pronounce and certify the deaths of patients. Inadequate knowledge of the Coroners Act (in the province of Ontario) and of the correct process of certifying death can make physicians uncomfortable when confronted with these tasks. OBJECTIVE OF PROGRAM To educate family physicians about how to perform the administrative tasks required of them when patients die. PROGRAM DESCRIPTION The program included an educational video, a tutorial outlining the process of death certification, and discussion with a regional coroner about key features of the Coroners Act. In small groups, participants worked through cases of patient deaths in which they were asked to determine whether a coroner needed to be involved, to determine the manner of death, and to complete a mock death certificate for each case. CONCLUSION All participants reported a high level of satisfaction with the workshop and thought the main objective of the program had been achieved. Results of a test given 3 months after the workshop showed substantial improvement in participants’ knowledge of the coroner’s role and of the process of death certification. PMID:17872782

    OBJECTIVE: To determine trends in the causes of death in a West African town. Mortality caused by infectious diseases is reported to be declining while degenerative and man-made mortality factors are increasingly significant. Most mortality analyses for sub-Saharan Africa have involved extrapolation and have not been derived from community-based data. METHODS: Historical data on causes of death coded by physicians were analysed for the urban population of Banjul for the period 1942-97. As the calculation of rates is not possible in the absence of a reliable population denominator, age-standardized proportional mortality ratios (PMRs) for men and women by major groups of causes of death were calculated, using the 1942-49 data for reference purposes. FINDINGS: Most deaths were attributable to communicable diseases. There was a shift in proportional mortality over the study period: the contribution of communicable diseases declined and that of noncommunicable diseases and injuries increased. These trends were more marked among men than women. CONCLUSION: The data illustrate that while noncommunicable diseases and injuries are emerging as important contributors to mortality in sub-Saharan Africa, communicable diseases remain significant causes of mortality and should not be neglected.

    Introduction Differences in risk for death from diseases and other causes among racial/ethnic groups likely contributed to the limited improvement in the state of health in the United States in the last few decades. The objective of this study was to identify causes of death that are the largest contributors to health disparities among racial/ethnic groups. Methods Using data from WONDER system, we measured the relative (age-adjusted mortality ratio [AAMR]) and absolute (difference in years of life lost [dYLL]) differences in mortality risk between the non-Hispanic white population and the black, Hispanic, American Indian/Alaska Native, and Asian/Pacific Islander populations for the 25 leading causes of death. Results Many causes contributed to disparities between non-Hispanic whites and blacks, led by assault (AAMR, 7.56; dYLL, 4.5 million). Malignant neoplasms were the second largest absolute contributor (dYLL, 3.8 million) to black–white disparities; we also found substantial relative and absolute differences for several cardiovascular diseases. Only assault, diabetes, and diseases of the liver contributed substantially to disparities between non-Hispanic whites and Hispanics (AAMR ≥ 1.65; dYLL ≥ 325,000). Many causes of death, led by assault (AAMR, 3.25; dYLL, 98,000), contributed to disparities between non-Hispanic whites and American Indians/Alaska Natives; Asian/Pacific Islanders did not have a higher risk than non-Hispanic whites for death from any disease. Conclusion Assault was a substantial contributor to disparities in mortality among non-Asian racial/ethnic minority populations. Research and intervention resources need to target diseases (such as diabetes and diseases of the liver) that affect certain racial/ethnic populations. PMID:25078566

    Background Decentralization and task shifting has significantly improved access to antiretroviral therapy (ART). Many studies conducted to determine the attrition rate in Ethiopia have not compared attrition rates between hospitals and health centers in a relatively recent cohort of patients. This study compared death and loss to follow-up (LTFU) rates among ART patients in hospitals and health centers in south Ethiopia. Methods Data routinely collected from patients aged older than 15 years who started ART between July 2011 and August 2012 in 20 selected health facilities (12 being hospitals) were analyzed. The outcomes of interest were LTFU and death. The data were entered, cleaned, and analyzed using Statistical Package for the Social Sciences version 20.0 and Stata version 12.0. Competing-risk regression models were used. Results The service years of the facilities were similar (median 8 and 7.5 for hospitals and health centers, respectively). The mean patient age was 33.7±9.6 years. The median baseline CD4 count was 179 (interquartile range 93–263) cells/mm3. A total of 2,356 person-years of observation were made with a median follow-up duration of 28 (interquartile range 22–31) months; 24.6% were either dead or LTFU, resulting in a retention rate of 75.4%. The death rates were 3.0 and 1.5 and the LTFU rate were 9.0 and 10.9 per 100 person-years of observation in health centers and hospitals, respectively. The competing-risk regression model showed that the gap between testing and initiation of ART, body mass index, World Health Organization clinical stage, isoniazid prophylaxis, age, facility type, and educational status were independently associated with LTFU. Moreover, baseline tuberculous disease, poor functional status, and follow-up at a health center were associated with an elevated probability of death. Conclusion We observed a higher death rate and a lower LTFU rate in health centers than in hospitals. Most of the associated variables were also

    Background Aortic aneurysm and dissection are important causes of death in older people. Ruptured aneurysms show catastrophic fatality rates reaching near 80%. Few population-based mortality studies have been published in the world and none in Brazil. The objective of the present study was to use multiple-cause-of-death methodology in the analysis of mortality trends related to aortic aneurysm and dissection in the state of Sao Paulo, between 1985 and 2009. Methods We analyzed mortality data from the Sao Paulo State Data Analysis System, selecting all death certificates on which aortic aneurysm and dissection were listed as a cause-of-death. The variables sex, age, season of the year, and underlying, associated or total mentions of causes of death were studied using standardized mortality rates, proportions and historical trends. Statistical analyses were performed by chi-square goodness-of-fit and H Kruskal-Wallis tests, and variance analysis. The joinpoint regression model was used to evaluate changes in age-standardized rates trends. A p value less than 0.05 was regarded as significant. Results Over a 25-year period, there were 42,615 deaths related to aortic aneurysm and dissection, of which 36,088 (84.7%) were identified as underlying cause and 6,527 (15.3%) as an associated cause-of-death. Dissection and ruptured aneurysms were considered as an underlying cause of death in 93% of the deaths. For the entire period, a significant increased trend of age-standardized death rates was observed in men and women, while certain non-significant decreases occurred from 1996/2004 until 2009. Abdominal aortic aneurysms and aortic dissections prevailed among men and aortic dissections and aortic aneurysms of unspecified site among women. In 1985 and 2009 death rates ratios of men to women were respectively 2.86 and 2.19, corresponding to a difference decrease between rates of 23.4%. For aortic dissection, ruptured and non-ruptured aneurysms, the overall mean ages at death

    Between 1903 and 1975 about 1 percent of climbers on Mount McKinley (Denali) and Mount Foraker in Alaska died. In 1976 a total of ten (1.7 percent) of 587 mountaineers died, but this rate of death was not significantly higher than previously. Nineteen percent of climbers in 1976 suffered major or minor injuries, illness or death. Acute mountain sickness (AMS), frostbite and fractures were common. Thirty-three rescues or retrievals of bodies were mounted at a cost of more than $82,000. Inexperience (particularly with arctic mountaineering), poor leadership, faulty equipment and undue reliance on rescue by helicopter contributed to the alarming incidence of accident, illness and death on big peaks in Mount McKinley National Park in 1976.

    Background The biomedical and psychosocial mechanisms underlying the relationship between self-rated health (SRH) and mortality in elderly individuals remain unclear. Objective To assess the association between different measurements of subjective health (global, age-comparative, and time-comparative SRH) and cause-specific mortality. Methods Neurological Disorders in Central Spain (NEDICES) is a prospective population-based survey of the prevalence and incidence of major age-associated conditions. Data on demographic and health-related variables were collected from 5,278 subjects (≥65 years) at the baseline questionnaire. Thirteen-year mortality and cause of death were obtained from the National Death Registry. Adjusted hazard ratios (aHR) for SRH and all-cause and cause-specific mortality were estimated by Cox proportional hazard models. Results At baseline, 4,958 participants (93.9%) answered the SRH questionnaire. At the end of follow-up 2,468 (49.8%) participants had died (of whom 723 [29.2%] died from cardiovascular diseases, 609 [24.7%] from cancer, and 359 [14.5%] from respiratory diseases). Global SRH predicted independently all-cause mortality (aHR for “poor or very poor” vs. “very good” category: 1.39; 95% confidence interval [CI]: 1.15–1.69). Analysis of cause-specific mortality revealed that global SRH was an independent predictor for death due to respiratory diseases (aHR for “poor or very poor” vs. “very good” category: 2.61; 95% CI: 1.55–4.39), whereas age-comparative SRH exhibited a gradient effect on the risk of death due to stroke. Time-comparative SRH provided small additional predictive value. Conclusions The predictive ability of SRH for mortality largely differs according to the specific cause of death, with the strongest associations found for respiratory disease and stroke mortality.

    One of the roles of nursing is to take care of the patients in terminal situation. The time, the experience, the formation, and the personal and professional attitudes that the nurse has will propitiate that taking care of moribund patients might turn into one of the more rewarding human experiences in life. There for, it is indispensable that nurses assume death as a natural and inevitable reality to achieve. The principal aim of the study is to evaluate the competence of confrontation and the autoefficiency of the welfare among nurses who work with adult patients at the end of the life. Descriptive study realized in the units of Oncology, Hametology and Palliative Care of the following centers: La Fe, Clínico, Dr. Peset, H. General, Arnau de Vilanova and Dr. Moliner de Portacoelli in Valencia (Spain). The following instruments were used: the Bugen Scale of confrontation of the Death (1980-1981) and the Robbins Scale of Autoefficiency (1992). Data suggests that major coping gives major autoeffciency and vice versa. The realized study opens numerous questions, specially related with training and the burden of preparation along the whole professional career, in order to achieve competence for coping and autoefficiency.

  1. Death rates in HIV-positive antiretroviral-naive patients with CD4 count greater than 350 cells per microL in Europe and North America: a pooled cohort observational study

    PubMed Central

    2011-01-01

    Background It is unclear whether antiretroviral (ART) naive HIV-positive individuals with high CD4 counts have a raised mortality risk compared with the general population, but this is relevant for considering earlier initiation of antiretroviral therapy. Methods Pooling data from 23 European and North American cohorts, we calculated country-, age-, sex-, and year-standardised mortality ratios (SMRs), stratifying by risk group. Included patients had at least one pre-ART CD4 count above 350 cells/mm3. The association between CD4 count and death rate was evaluated using Poisson regression methods. Findings Of 40,830 patients contributing 80,682 person-years of follow up with CD4 count above 350 cells/mm3, 419 (1.0%) died. The SMRs (95% confidence interval) were 1.30 (1.06-1.58) in homosexual men, and 2.94 (2.28-3.73) and 9.37 (8.13-10.75) in the heterosexual and IDU risk groups respectively. CD4 count above 500 cells/mm3 was associated with a lower death rate than 350-499 cells/mm3: adjusted rate ratios (95% confidence intervals) for 500-699 cells/mm3 and above 700 cells/mm3 were 0.77 (0.61-0.95) and 0.66 (0.52-0.85) respectively. Interpretation In HIV-infected ART-naive patients with high CD4 counts, death rates were raised compared with the general population. In homosexual men this was modest, suggesting that a proportion of the increased risk in other groups is due to confounding by other factors. Even in this high CD4 count range, lower CD4 count was associated with raised mortality. PMID:20638118

    In depth confidential inquiries on all post-perinatal infant deaths were carried out for two years in North and Southern Derbyshire District Health Authorities in order to explore why the postperinatal death rates and cot death rates have been consistently higher in Southern than in North Derbyshire. It was found that the death rates for probably inevitable deaths and for 'idiopathic' cot deaths were the same in both districts. The differences in the death rates lay in the group of partly explained cot deaths. Adverse social factors associated with each death were recorded and an estimate made of their relevance to the individual deaths. The group of deaths most amenable to intervention was those of category B (partly explained cot deaths). As judged by the Jarman index there are more areas of deprivation in Southern than in North Derbyshire. PMID:1776890

    Secondary age standards are valuable in intra- and interlaboratory calibration. At present very few such standards are available for fission track dating that is older than Tertiary. Several altered volcanic ash beds occur in the Middle Jurassic Carmel Formation in southwestern Utah. The formation was deposited in a shallow marine/sabhka environment. Near Gunlock, Utah, eight ash beds have been identified. Sanidines from one of the ash beds (GUN-F) give a single-crystal laser-probe 40Ar/39Ar age of 166.3??0.8 Ma (2??). Apatite and zircon fission track ages range from 152-185 Ma with typically 15-20 Ma errors (2??). Track densities in zircons are high and most grains are not countable. Apatites are fairly common in most of the ash beds and have reasonable track densities ranging between 1.2-1.5 ?? 106 tracks/cm2. Track length distributions in apatites are unimodal, have standard deviations <1??m, and mean track lengths of about 14-14.5 ??m. High Cl apatites (F:Cl:OH ratio of 39:33:28) are particularly abundant and large in ash GUN-F, and are fairly easy to concentrate, but the concentrates contain some siderite, most of which can be removed by sieving. GUN-F shows evidence of some reworking and detriaal contamination based on older single grain 40Ar/39Ar analyses and some rounding of grains, but the apatite population appears to be largely uncontaminated. At present BJK has approximately 12 of apatite separate from GUN-F. ?? 1993.

    Objectives. To compare suicide rates in Aboriginal communities in Labrador, including Innu, Inuit, and Southern Inuit, with the general population of Newfoundland, Canada. Methods. In partnership with Aboriginal governments, we conducted a population-based study to understand patterns of suicide mortality in Labrador. We analyzed suicide mortality data from 1993 to 2009 from the Vital Statistics Death Database. We combined this with community-based methods, including consultations with Elders, youths, mental health and community workers, primary care clinicians, and government decision-makers. Results. The suicide rate was higher in Labrador than in Newfoundland. This trend persisted across all age groups; however, the disparity was greatest among those aged 10 to 19 years. Males accounted for the majority of deaths, although suicide rates were elevated among females in the Inuit communities. When comparing Aboriginal subregions, the Innu and Inuit communities had the highest age-standardized mortality rates of, respectively, 165.6 and 114.0 suicides per 100 000 person-years. Conclusions. Suicide disproportionately affects Innu and Inuit populations in Labrador. Suicide rates were high among male youths and Inuit females. PMID:27196659

    Background Acute myeloid leukemia (AML) is treated with conventional induction chemotherapy shortly after diagnosis for most patients ≤ 65 years old. A recent report suggested a substantial decline in the early, or one-month, mortality rate in patients treated on clinical trials over the past 2 decades. It is unknown if a similar improvement has been observed in the general population. Methods We examined the one-month mortality in a large population-based series of 9,380 AML patients ≤ age 65 diagnosed and treated with chemotherapy between 1973 and 2010. Results We observed a significant decline in the one-month mortality rate from 18.7% among patients diagnosed from 1973–1977 (95% CI 16.4–21.2%) to 5.8% for those diagnosed in 2008–2010 (95% CI 4.5–7.6%) (p-value < 0.001). Median overall survival (OS) improved significantly from 6 months (95% CI 5–7) in 1973–1977 to 23 months (95% CI 16–20) in 2008–2010 (p-value < 0.001). Though age and geographic variation significantly influenced one-month mortality in 1973–1977, these differences in one-month mortality were no longer significant in AML patients treated more recently (2008–2010). Conclusions Over the past four decades, early mortality has become uncommon in younger patients (≤ 65 years) with newly diagnosed AML undergoing induction chemotherapy. It is encouraging that the improvements seen in one-month mortality in a selective cohort of clinical trial patients are also observed in a population-based analysis. PMID:25739348

    Low heart rate variability (HRV) has been linked to increased total mortality in the general population; however, the relationship between low HRV and sudden cardiac death (SCD) is less well-characterized. The goal of this study was to evaluate the relationship between low HRV and SCD in a community-based cohort. Our cohort consisted of 12,543 participants from the Atherosclerosis Risk in Communities (ARIC) study. HRV measures were derived from 2-minute electrocardiogram recordings obtained during the baseline exam (1987-89). Time domain measurements included the standard deviation of all normal RR intervals (SDNN) and the root mean squared successive difference (r-MSSD). Frequency domain measurements included low frequency power (LF) and high frequency (HF) power. During a median follow-up of 13 years, 215 SCDs were identified from physician adjudication of all coronary heart disease deaths through 2001. In multivariable adjusted Cox proportional hazards models, each standard deviation decrement in SDNN, LF, and HF were associated with 24%, 27% and 16% increase in SCD risk, respectively. Low HRV is independently associated with increased risk of SCD in the general population. PMID:27551828

    Low heart rate variability (HRV) has been linked to increased total mortality in the general population; however, the relationship between low HRV and sudden cardiac death (SCD) is less well-characterized. The goal of this study was to evaluate the relationship between low HRV and SCD in a community-based cohort. Our cohort consisted of 12,543 participants from the Atherosclerosis Risk in Communities (ARIC) study. HRV measures were derived from 2-minute electrocardiogram recordings obtained during the baseline exam (1987–89). Time domain measurements included the standard deviation of all normal RR intervals (SDNN) and the root mean squared successive difference (r-MSSD). Frequency domain measurements included low frequency power (LF) and high frequency (HF) power. During a median follow-up of 13 years, 215 SCDs were identified from physician adjudication of all coronary heart disease deaths through 2001. In multivariable adjusted Cox proportional hazards models, each standard deviation decrement in SDNN, LF, and HF were associated with 24%, 27% and 16% increase in SCD risk, respectively. Low HRV is independently associated with increased risk of SCD in the general population. PMID:27551828

  12. Death: 'nothing' gives insight.

    PubMed

    Ettema, Eric J

    2013-08-01

    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 of itself. This leads to an ontological paradox in which death is both acknowledged and denied: death is … nothing. In this article, I investigate whether insight into the ontological paradox of the nothingness of death can contribute to a good end-of-life. By analysing Aquinas', Heidegger's and Derrida's understanding of death as nothingness, I explore how giving meaning to death on different ontological levels connects to, and at the same time provides resistance against, the harsh reality of death. By doing so, I intend to demonstrate that insight into the nothingness of death can count as a framework for a meaningful dealing with death.

    Sudden death is defined as the death occurring less than one hour before the onset of the patient's symptoms. It is a severe condition considered a public health issue in several countries and in ours, it accounts for 33 000 to 53 000 annual deaths mainly related to ischemic heart disease. The main cause of sudden death are severe ventricular arrhythmias, but determining what patients are at risk for such an episode is complex, that is why risk stratification is usually a low cost-effective intervention. In the present study, we describe different sudden death risk-stratification strategies. Different sudden death treatment strategies regarding general population have different success rates in different countries, nevertheless, among select high risk populations; the best therapy currently available is the automatic implantable cardioverter-defibrillator. We also discuss other treatment options. In Mexico it is deemed necessary to do an important effort for the early detection, prevention and treatment of sudden death in order to limit the consequences of this problem. PMID:15892455

    Amenable mortality (AM) is an indicator of medical care quality. This study aimed to assess the trend and magnitude of AM in Mongolia, with the purpose of providing evidence for decisions on resource allocation. This is the first study on AM trends in Mongolia. Retrospective analysis was done on mortality statistics for the period 2007-2014. Causes of death were coded according to the 10th revision of the International Classification of Diseases (ICD-10). Nolte & McKee's classification of AM was used for the estimation of amenable mortality rates (AMRs) in Mongolia. During the study period, a total of 130,402 deaths were registered in Mongolia, of which 44,800 (34.4%) deaths were classified as being amenable. The age-standardized AMR per 100,000 population was highest in 2007 (226.6), and declined continuously until the level of 169.2 in 2014. The rate remained consistently higher in males than in females. Cerebrovascular diseases, ischemic heart diseases, perinatal deaths, influenza/pneumonia/asthma and tuberculosis were the leading causes of AM in the past eight years in Mongolia. The AMR was higher in remote western provinces with harsh weather conditions, high poverty rates, lack of human resources for health, and poor infrastructure. In addition, the provinces where Mongolia's ethnic minorities live tended to have a higher AMR. The government of Mongolia needs to critically look at the regional differences in AM in order to allocate health resources, including human resources, effectively. Further studies are needed to look into the causes of regional disparities in AM, individual-level risk factors to amenable deaths, and validity of death coding in health sector. PMID:27019528

  17. Improving the accuracy of death certification

    BACKGROUND: Population-based mortality statistics are derived from the information recorded on death certificates. This information is used for many important purposes, such as the development of public health programs and the allocation of health care resources. Although most physicians are confronted with the task of completing death certificates, many do not receive adequate training in this skill. Resulting inaccuracies in information undermine the quality of the data derived from death certificates. METHODS: An educational intervention was designed and implemented to improve internal medicine residents' accuracy in death certificate completion. A total of 229 death certificates (146 completed before and 83 completed after the intervention) were audited for major and minor errors, and the rates of errors before and after the intervention were compared. RESULTS: Major errors were identified on 32.9% of the death certificates completed before the intervention, a rate comparable to previously reported rates for internal medicine services in teaching hospitals. Following the intervention the major error rate decreased to 15.7% (p = 0.01). The reduction in the major error rate was accounted for by significant reductions in the rate of listing of mechanism of death without a legitimate underlying cause of death (15.8% v. 4.8%) (p = 0.01) and the rate of improper sequencing of death certificate information (15.8% v. 6.0%) (p = 0.03). INTERPRETATION: Errors are common in the completion of death certificates in the inpatient teaching hospital setting. The accuracy of death certification can be improved with the implementation of a simple educational intervention. PMID:9614825

    Cervical cancer kills 260,000 women annually, and nearly 85% of these deaths occur in developing nations, where it is the leading cause of cancer deaths in women. Disparities of health and poverty play a large role in this high mortality rate. Whereas routine Papanicolaou and human papillomavirus (HPV) testing has dramatically reduced cervical cancer deaths in Western nations, without proper infrastructure, facilities, and medical training, the rates of cervical cancer in developing nations will remain high. Studies on HPV DNA testing and the low-technology method of "screen and treat" are promising. In addition, reducing the cost and increasing the availability of HPV vaccines in developing nations brings hope and promise to the next generation of women. PMID:20111660

    Apoptosis-programed cell death-is the most common form of death in the body. Once apoptosis is induced, proper execution of the cell death program requires the coordinated activation and execution of multiple molecular processes. Here, we describe the pathways and the basic components of the death-inducing machinery. Since apoptosis is a key regulator of tissue homeostasis, an imbalance of apoptosis results in severe diseases like cancer, autoimmunity, and AIDS.

    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. PMID:24212662

    The purpose of this study was to describe mortality patterns among the elderly using single versus multiple cause of death data and examine ways that multiple cause of death data can best be processed, analyzed and presented. Deaths among white California aged 65 and older for the years 1970, 1975 and 1980 were analyzed. Overall, mortality rates decreased over time, at all ages and for both sexes but more so for females, although the number of causes of death increased with age. Underlying cause mortality rates were compared to rates based on any mention of a cause on the death certificate; diabetes and atherosclerosis were more frequent causes of both than would be indicated by single cause statistics, and heart diseases other than ischemic heart disease increased in mentions on the death certificated while ischemic heart disease underlying mortality rates decreased. Pairs of causes of death showed increased likelihood of occurrence of a number of combinations of chronic diseases. In all pair combinations studied, the addition of another serious chronic disease lowered the mean age of death resulted in an older mean age of death. This result combined with higher number of causes per death but lower mortality rates among females raised interesting questions about interpreting more causes on death certificates as an indication of a sicker person at time of death. This study confirmed morbidity and mortality work on other that mortality of older adults in decreasing but that the number of causes of death per person is increasing. 82 refs., 30 figs., 59 tabs.

    OBJECTIVE To review the frequency of and factors associated with fetal death in the Brazilian scientific literature. METHODS A systematic review of Brazilian studies on fetal deaths published between 2003 and 2013 was conducted. In total, 27 studies were analyzed; of these, 4 studies addressed the quality of data, 12 were descriptive studies, and 11 studies evaluated the factors associated with fetal death. The databases searched were PubMed and Lilacs, and data extraction and synthesis were independently performed by two or more examiners. RESULTS The level of completeness of fetal death certificates was deficient, both in the completion of variables, particularly sociodemographic variables, and in defining the underlying causes of death. Fetal deaths have decreased in Brazil; however, inequalities persist. Analysis of the causes of death indicated maternal morbidities that could be prevented and treated. The main factors associated with fetal deaths were absent or inadequate prenatal care, low education level, maternal morbidity, and adverse reproductive history. CONCLUSIONS Prenatal care should prioritize women that are most vulnerable (considering their social environment or their reproductive history and morbidities) with the aim of decreasing the fetal mortality rate in Brazil. Adequate completion of death certificates and investment in the committees that investigate fetal and infant deaths are necessary. PMID:25902565

    Pesticide poisoning has been recognized as an important public health issue around the world. The objectives of this study were to report nationally representative figures on mortality from and the incidence of pesticide poisoning in South Korea and to describe their epidemiologic characteristics. We calculated the age-standardized rates of mortality from and the incidence of pesticide poisoning in South Korea by gender and region from 2006 through 2010 using registered death data obtained from Statistics Korea and national healthcare utilization data obtained from the National Health Insurance Review and Assessment Service of South Korea. During the study period of 2006 through 2010, a total of 16,161 deaths and 45,291 patients related to pesticide poisoning were identified, marking respective mortality and incidence rates of 5.35 and 15.37 per 100,000 population. Intentional self-poisoning was identified as the major cause of death due to pesticides (85.9%) and accounted for 20.8% of all recorded suicides. The rates of mortality due to and incidence of pesticide poisoning were higher in rural than in urban areas, and this rural-urban discrepancy was more pronounced for mortality than for incidence. Both the rate of mortality due to pesticide poisoning and its incidence rate increased with age and were higher among men than women. This study provides the magnitude and epidemiologic characteristics for mortality from and the incidence of pesticide poisoning at the national level, and strongly suggests the need for further efforts to prevent pesticide self-poisonings, especially in rural areas in South Korea.

    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 (p<0.02), and significantly more common compared to reference deaths (p<0.002). Co-sleeping deaths were also more frequent at weekends. Almost half of all SUDI (49%) occurred in the summer months – more than twice the frequency of reference deaths. While sharing 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. PMID:16457407

    Nationally, death rates from prescription opioid pain reliever (OPR) overdoses quadrupled during 1999-2010, whereas rates from heroin overdoses increased by <50%. Individual states and cities have reported substantial increases in deaths from heroin overdose since 2010. CDC analyzed recent mortality data from 28 states to determine the scope of the heroin overdose death increase and to determine whether increases were associated with changes in OPR overdose death rates since 2010. This report summarizes the results of that analysis, which found that, from 2010 to 2012, the death rate from heroin overdose for the 28 states increased from 1.0 to 2.1 per 100,000, whereas the death rate from OPR overdose declined from 6.0 per 100,000 in 2010 to 5.6 per 100,000 in 2012. Heroin overdose death rates increased significantly for both sexes, all age groups, all census regions, and all racial/ethnic groups other than American Indians/Alaska Natives. OPR overdose mortality declined significantly among males, persons aged <45 years, persons in the South, and non-Hispanic whites. Five states had increases in the OPR death rate, seven states had decreases, and 16 states had no change. Of the 18 states with statistically reliable heroin overdose death rates (i.e., rates based on at least 20 deaths), 15 states reported increases. Decreases in OPR death rates were not associated with increases in heroin death rates. The findings indicate a need for intensified prevention efforts aimed at reducing overdose deaths from all types of opioids while recognizing the demographic differences between the heroin and OPR-using populations. Efforts to prevent expansion of the number of OPR users who might use heroin when it is available should continue.

    Death certificate data are often used to study the epidemiology of poisoning deaths, but the International Classification of Diseases (ICD) codes used to tabulate death data do not convey all of the available information about the drugs and other substances named on death certificates. In the United States and some other countries, the SuperMICAR computer system is used to assign ICD codes to deaths. The SuperMICAR system also stores a verbatim record of the text entered for the cause of death. We used the SuperMICAR text entries to study the 7,817 poisoning deaths that occurred among Washington State residents between 2003 and 2010. We tabulated the drugs named on death certificates and computed age-adjusted and age-specific death rates for the top-named drugs and for prescription and illicit drugs. Methadone was named on 2,149 death certificates and was the most frequently named substance, followed by alcohol, opiate, cocaine, oxycodone, and methamphetamine. For both men and women and at all ages, prescription drugs were involved in more deaths than were illicit drugs. Among the 25 drugs named most frequently, only 4 have unique ICD codes; the other 21 can be identified only by using the SuperMICAR data.

    Death certificates serve the critical functions of providing documentation for legal/administrative purposes and vital statistics for epidemiologic/health policy purposes. In order to satisfy these functions, it is important that death certificates be filled out completely, accurately, and promptly. The high error rate in death certification has been documented in multiple prior studies, as has the effectiveness of educational training interventions at mitigating errors. The following guide to death certification is intended to illustrate some basic principles and common pitfalls in electronic death registration with the goal of improving death certification accuracy.

    How one defines death may vary. It is important for clinicians to recognize those aspects of a patient’s religious beliefs that may directly influence medical care and how such practices may interface with local laws governing the determination of death. Debate continues about the validity and certainty of brain death criteria within Islamic traditions. A search of PubMed, Scopus, EMBASE, Web of Science, PsycNet, Sociological Abstracts, DIALOGUE ProQuest, Lexus Nexus, Google, and applicable religious texts was conducted to address the question of whether brain death is accepted as true death among Islamic scholars and clinicians and to discuss how divergent opinions may affect clinical care. The results of the literature review inform this discussion. Brain death has been acknowledged as representing true death by many Muslim scholars and medical organizations, including the Islamic Fiqh Academies of the Organization of the Islamic Conference and the Muslim World League, the Islamic Medical Association of North America, and other faith-based medical organizations as well as legal rulings by multiple Islamic nations. However, consensus in the Muslim world is not unanimous, and a sizable minority accepts death by cardiopulmonary criteria only. PMID:25287999

    Reactions to claims of near-death experiences (NDE) range from the popular view that this must be evidence for life after death, to outright rejection of the experiences as, at best, drug induced hallucinations or, at worse, pure invention. Twenty years, and much research, later, it is clear that neither extreme is correct.

    Of sudden natural deaths while driving, 126 occurred during 1980 through 1985 in the northern half of Sweden. The mean age of the 69 car driver victims was 59 years, considerably higher than that of traumatic car deaths, and all but 2 were males. The mean age of 57 operators of other vehicles was 66 years, and of these, 6 were women. Seven car drivers were stricken during commercial employment. Most accidents occurred during daytime and the distribution of the weekdays was fairly even. Ischemic heart disease accounted for 112 deaths, and other cardiovascular diseases for an additional 9 deaths. Only 1/5 of the victims experienced previous symptoms of disease. Out of at least 31 other persons at risk in the car deaths, only 2 passengers suffered minor injuries. The trauma in the deceased was in most cases minor in both car and other vehicle deaths. Property damage was also minimal. At least 1/3 of the drivers were able to stop the car before becoming unconscious. In none of the car cases was alcohol detected in the blood, while alcohol was identified in at least 2 of the other vehicle victims. The findings here agree with previous studies that natural deaths at the wheel are fairly uncommon, and that the risk for other persons is not significant. The value of adequate postmortem examinations of drivers dying in traffic is stressed--natural deaths can otherwise be overlooked. PMID:3612079

    Does it matter that the hearts of 'brainstem dead' patients may persist in beating spontaneously? Hostile reactions, to the Danish inclusion of cardiac criteria in the determination of death, betray reductionist views of human life at the core of 'brainstem' conceptions of death. Such views (whether centred on neurological function or on abstractions concerning 'personhood') supplant the richness of human life and death with the poverty of essentialism: and mask the lethal nature of beating-heart organ retrieval. The affirmation of cardiac criteria for death is not an alternative form of essentialism as some critics suppose, but part of an understanding of human life and death which rejects essentialism altogether. The spontaneously persistent heartbeat does not constitute human life, but most certainly counts for it. PMID:2287015

  12. Programmed Death in Bacteria

    PubMed Central

    Lewis, Kim

    2000-01-01

    Programmed cell death (PCD) in bacteria plays an important role in developmental processes, such as lysis of the mother cell during sporulation of Bacillus subtilis and lysis of vegetative cells in fruiting body formation of Myxococcus xanthus. The signal transduction pathway leading to autolysis of the mother cell includes the terminal sporulation sigma factor EςK, which induces the synthesis of autolysins CwlC and CwlH. An activator of autolysin in this and other PCD processes is yet to be identified. Autolysis plays a role in genetic exchange in Streptococcus pneumoniae, and the gene for the major autolysin, lytA, is located in the same operon with recA. DNA from lysed cells is picked up by their neighbors and recombined into the chromosome by RecA. LytA requires an unknown activator controlled by a sensory kinase, VncS. Deletion of vncS inhibits autolysis and also decreases killing by unrelated antibiotics. This observation suggests that PCD in bacteria serves to eliminate damaged cells, similar to apoptosis of defective cells in metazoa. The presence of genes affecting survival without changing growth sensitivity to antibiotics (vncS, lytA, hipAB, sulA, and mar) indicates that bacteria are able to control their fate. Elimination of defective cells could limit the spread of a viral infection and donate nutrients to healthy kin cells. An altruistic suicide would be challenged by the appearance of asocial mutants without PCD and by the possibility of maladaptive total suicide in response to a uniformly present lethal factor or nutrient depletion. It is proposed that a low rate of mutation serves to decrease the probability that asocial mutants without PCD will take over the population. It is suggested that PCD is disabled in persistors, rare cells that are resistant to killing, to ensure population survival. It is suggested that lack of nutrients leads to the stringent response that suppresses PCD, producing a state of tolerance to antibiotics, allowing cells to

    Introduction: Natural and unexpected death that happens within less than one hour of first symptom occurrence is called sudden death. Cardiovascular diseases are the main known reason of sudden death and more than 75% of sudden deaths in athletes are assigned to it. Here we reported the autopsy results of all cases with sudden death following exercise that were referred to forensic center of Tehran, Iran, from 2009 to 2014. Methods: In this cross sectional study all subjects who were registered to forensic medicine center of Tehran, Iran, from 2009 to 2014, as a case of sudden death following exercise were evaluated. Demographic data and medical history as well as autopsy and toxicology findings were retrospectively gathered using profiles of the deceased. Results were reported using descriptive analysis. Results: 14 cases were registered as sudden death following exercise in forensic medicine profiles during the study period. Exploring the files of the mentioned deceased, revealed five non-compatible cases in this regard. Finally, 9 eligible cases were enrolled (88.9% male). The mean age of the deceased was 28.66 ± 10.86 years (range: 7 – 40). Toxicological tests were available for 7 cases, one of which was positive for tramadol. Sudden death following football was reported most frequently (44.4%). Only 3 (33.3%) cases had herald signs such as chest pain, syncope, or loss of consciousness. 1 case (11.11%) had a positive history of sudden death in relatives. Conclusion: Although most sudden death victims are asymptomatic until the event, all those who suffer from symptoms such as chest pain, shortness of breath, dizziness, fatigue and irregular heart rate during physical activities, should be screened regarding common probable causes of sudden death.

    Methods: 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. Results: 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. Conclusions: 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. PMID:16326764

    Fortunately, anthropology has brought to our modern society a higher interest for mankind's cultural dimension and the values which each people employ in order to make sense out of the changes which occur during our lives. It is this cultural dimension which permits men to develop our innate capacities and to become humans. However, in order to achieve this, we need experiences which are codified and interpreted by a values system which each individual has made his/her own. Some of these experiences take place inside cultural mores constructed expressly so that they are useful for one's lifestyle; these are known as rites. A rite, therefore, is an experience which leaves an impression, which implies social and biographical changes, which provides meaning to human beings' universal interests. Nonetheless, since rites usually are organized by diverse religions, it is convenient, as we enter the 21st Century, to speak about Experiences which Activate Structures as means to approach, to come to grasp with, some of the great causes of anxiety in humans: death and insanity. These Experiences which Activate Structures allow us to subjectively experiment, to conquer our fears and to be more conscious of our here and our now. Workshops on the Living Integration of One's Own Death are included in this context as an appropriate forum through which to approach death with knowledge and serenity, inducing changes in our own lifestyle as well and helping us to overcome situations of existential blockage.

    In contrast to usual sudden death seen in the course of coronary artery disease, individuals dying suddenly from other causes form a complex array of situations. In some the causes are readily identifiable. No simple pattern is available to identify the potential candidate, but on review of the many causes some moves by the physician may be helpful. For example, a more complete physical evaluation of young individuals participating in competitive athletics is in order. This is particularly true if the athlete reports an episode of unexplained syncope. This may well be the warning of a propensity towards sudden death under physical and emotional stress. Knowledge of the specific problems in underwater swimming and diving, in high altitude exposure and in various circumstances such as certain weight reduction diets and industrial exposures may lead to control of some types of unusual sudden death. Clearly, more studies are needed to give answers in so called crib death. As the incidence of usual sudden death falls, these unusual forms of sudden death will represent a more important fraction of sudden death in general. PMID:6537674

    In this study, a questionnaire was administered to 142 students at two high schools (72 boys and 70 girls) and 112 students at a state college (36 men and 76 women) to determine whether they favored the death penalty for certain criminal acts. A questionnaire was also administered to assess extraversion and neuroticism. The findings indicated that high school students rated more criminal acts as meriting the death penalty than did college students. Gender and personality were not found to be associated with attitudes toward the death penalty.

  19. Unnatural sudden infant death

    PubMed Central

    Meadow, R.

    1999-01-01

    AIM—To identify features to help paediatricians differentiate between natural and unnatural infant deaths.
METHOD—Clinical features of 81 children judged by criminal and family courts to have been killed by their parents were studied. Health and social service records, court documents, and records from meetings with parents, relatives, and social workers were studied.
RESULTS—Initially, 42 children had been certified as dying from sudden infant death syndrome (SIDS), and 29 were given another cause of natural death. In 24 families, more than one child died; 58died before the age of 6 months and most died in the afternoon or evening. Seventy per cent had experienced unexplained illnesses; over half were admitted to hospital within the previous month, and 15 had been discharged within 24 hours of death. The mother, father, or both were responsible for death in 43, five, and two families, respectively. Most homes were disadvantaged—no regular income, receiving income support—and mothers smoked. Half the perpetrators had a history of somatising or factitious disorder. Death was usually by smothering and 43% of children had bruises, petechiae, or blood on the face.
CONCLUSIONS—Although certain features are indicative of unnatural infant death, some are also associated with SIDS. Despite the recent reduction in numbers of infants dying suddenly, inadequacies in the assessment of their deaths exist. Until a thorough postmortem examination is combined with evaluation of the history and circumstances of death by an experienced paediatrician, most cases of covert fatal abuse will go undetected. The term SIDS requires revision or abandonment.

    Macro-autophagy (hereafter referred to as autophagy) delivers cytoplasmic material to the lysosome for degradation, and has been implicated in many cellular processes, including stress, infection, survival, and death. While the regulation and role that autophagy plays in stress, infection, and survival is apparent, the regulation of and role that autophagy has during cell death remains relatively unclear. In this review, we highlight what is known about the role that autophagy can play during physiological cell death, and discuss the implications of better understanding cellular destruction that involves autophagy.

    New technologies in medicine dramatically open a twilight-zone of ignorance between life and death. The argument shows that the present definition of brain death as the death of a human person is a convention with a specific philosophy behind. You will meet the problem with more accuracy when referring to an ethics of intransparence that allows an individual decision with respect to certain qualified conditions. Only from this starting-point the informed ex ante consent for an organ donation seems to become the only conclusive but at the same time justified decision.

    2016-01-01

    While anthropological studies in non-Western societies show how funerals protect the community from the threat of death, sociological studies of British funerals have so far focused on meanings for the private family. The article reports on results from a Mass Observation directive – the first British study to focus specifically on the entire funeral congregation – and shows how attendees experience the contemporary life-centred funeral as a symbolic conquest of death. While the eulogy’s accuracy is important, even more so – at least for some – is its authenticity, namely that the speaker has personal knowledge of the deceased. Whereas Davies analyses the power of professionally delivered ritual words against death, our data reveals how admired is the courage exercised by non-professionals in speaking against death, however faltering their words. Further, the very presence of a congregation whose members have known the deceased in diverse ways embodies a configurational eulogy, which we term relationships against death. We thus argue that funerals symbolically conquer death not only through words delivered by ritual specialists, but also through those who knew the deceased congregating and speaking. PMID:27019605

    Clarke, Peter G.H.; Puyal, Julien

    2012-01-01

    The term autophagic cell death (ACD) initially referred to cell death with greatly enhanced autophagy, but is increasingly used to imply a death-mediating role of autophagy, as shown by a protective effect of autophagy inhibition. In addition, many authors require that autophagic cell death must not involve apoptosis or necrosis. Adopting these new and restrictive criteria, and emphasizing their own failure to protect human osteosarcoma cells by autophagy inhibition, the authors of a recent Editor’s Corner article in this journal argued for the extreme rarity or nonexistence of autophagic cell death. We here maintain that, even with the more stringent recent criteria, autophagic cell death exists in several situations, some of which were ignored by the Editor’s Corner authors. We reject their additional criterion that the autophagy in ACD must be the agent of ultimate cell dismantlement. And we argue that rapidly dividing mammalian cells such as cancer cells are not the most likely situation for finding pure ACD. PMID:22652592

    Different types of cell death are often defined by morphological criteria, without a clear reference to precise biochemical mechanisms. The Nomenclature Committee on Cell Death (NCCD) proposes unified criteria for the definition of cell death and of its different morphologies, while formulating several caveats against the misuse of words and concepts that slow down progress in the area of cell death research. Authors, reviewers and editors of scientific periodicals are invited to abandon expressions like ‘percentage apoptosis’ and to replace them with more accurate descriptions of the biochemical and cellular parameters that are actually measured. Moreover, at the present stage, it should be accepted that caspase-independent mechanisms can cooperate with (or substitute for) caspases in the execution of lethal signaling pathways and that ‘autophagic cell death’ is a type of cell death occurring together with (but not necessarily by) autophagic vacuolization. This study details the 2009 recommendations of the NCCD on the use of cell death-related terminology including ‘entosis’, ‘mitotic catastrophe’, ‘necrosis’, ‘necroptosis’ and ‘pyroptosis’.

They live in war conditions; the houses of half of them have been demolished. The Death Obsession Scale (DOS) was administered. Its alpha reliability was .92, denoting high internal consistency. Among women, it yielded 1 factor, (General Death Obsession), whereas among men it yielded 3 factors: Death Rumination, Death Dominance, and Death Idea Repetition. Palestinian men and women attained significantly lower DOS mean scores than participants from 4 Arab countries: Egypt, Kuwait, Syria, and Lebanon in 7 out of 8 comparisons. However, Palestinian women had significantly higher DOS mean score than their Spanish, American and British counterparts, whereas Palestinian men had significantly higher mean DOS score than Spanish peers. The low DOS scores of Palestinians, in proportion to other Arab samples, may reflect their adaptation to strife and violence.

    Migration may be a high-risk period. In a study involving three species of raptor migrating from Europe to Sub-Saharan Africa, Klaassen et al. (2014) satellite-tracked 51 out of 69 birds to their deaths and showed that rate of mortality during migration was 6x that during stationary phases when birds were on their winter and summer grounds. Travel across the Sahara was particularly risky. Satellite tracking has also been used to infer mortality in other taxa (e.g. sea turtles) and may allow high-risk hotspots to be identified for wide-ranging species.

  14. Correction of vital statistics based on a proactive search of deaths and live births: evidence from a study of the North and Northeast regions of Brazil

    PubMed Central

    2014-01-01

    Background In the last 20 years, Brazil has undergone dramatic changes in terms of socioeconomic development and health care. In the first decade of the 2000s, the Ministry of Health (MoH) developed a series of programs focused on reducing infant mortality, including the Family Health Program as a national policy for primary care. In this paper, we propose a method to correct underreporting of deaths and live births. After vital statistics are corrected, infant mortality trends are analyzed for the period 2000–2010 by macro-geographical region. Methods A proactive search of live births and deaths was carried out in the Amazon and Northeast regions in 2010 to find vital events that occurred in 2008 and were not reported to the Ministry of Health. The probabilistic sample of 133 municipalities was stratified by adequacy of vital information reporting. For each municipality, the adequacy analysis was based on the reported age-standardized mortality rate per 1,000 population and the ratio between reported and estimated live births. Correction factors were estimated by strata based on additional vital events found in the proactive search. The procedure was generalized to correct municipal vital statistics for the period 2000–2010. Results In the proactive search, 35% of non-reported deaths were found within the health system (hospitals and other health establishments), but 28% were found in non-official sources, like illegal cemeteries. In areas of extreme poverty and unreliable vital information, the estimated completeness of infant death reporting was only 33%. After correction of vital information, the estimated infant mortality rate decreased from 26.1 in 2000 to 16.0 in 2010, with an annual rate of decrease of 4.7%, greater than the required rate to achieve the Millennium Development Goal. Among Brazilian regions, the Northeast showed the largest decrease, from 38.4 to 20.1 per 1,000 live births. Conclusions The proactive search for vital events was shown to

    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.

    Adolescence, between the ages of 10 and 19 years, is a unique period both physically and emotionally. During this time of life, individuals are known to experiment and engage in risky behavior, sometimes with unforeseen morbidity and mortality. We also see suicide emerge as a manner of death in this age group. The most common method is gunshot wound and sometimes in the form of Russian roulette. Few studies have looked at deaths by Russian roulette, the victims, and scenarios. In particular, no study examines the adolescent victim of Russian roulette. To better understand and classify this entity, adolescent Russian roulette autopsy cases over a 20-year period were examined looking at the victims, scenarios, autopsy findings, cause and manner of death, and the weapons. All victims were males, ages 13 to 19 years, with a Black-to-White ratio of 1:1. No victim had a previous psychiatric history. Toxicology was positive for alcohol and/or marijuana in 50% of the victims. Friends were present when the victim shot himself which occurred in the home the majority of the time. In all but 1 case, premeditation of the game was involved as the victim provided the weapon for the roulette. The cause of death was gunshot wound to the head (6 to the right side, 1 to the mouth, 1 to the forehead), and the manner of death was suicide in 6 cases and accident in 2 cases. A review of the literature discusses the adolescent victim, suicide, and Russian roulette.

    French, D; Catney, D; Gavin, AT

    2006-01-01

    Background An ageing population has service planners concerned about future levels of disease which are age dependent. Predictions of mortality for colorectal, lung and breast cancers, which account for 30% of cancer cases and 40% of cancers deaths, were calculated for 2010 and 2015, based on trends in death rates and the predicted change in the demography of the Northern Ireland population. Methods The US National Cancer Institute's “Joinpoint” program was used to check for structural breaks in the time series of cancer death rates from 1984 to 2004. The prediction models applied to the data allowed variations in trends across age groups to be taken into account. A linear model was used for increasing or constant trends and a log linear model was used where the trend was decreasing. The models assume the number of deaths in each stratum, defined by age-sex and time-period, is Poisson distributed, with the average value determined by a log or linear function. Results Recent trends in rates of cancers studied were downwards except for female lung. Predictions include decreased colorectal cancer deaths in females and lung cancer deaths in males. In females, lung cancer deaths are predicted to more than double by the year 2015 (473 deaths), based on the 1984 level. Colorectal death rates in males are predicted to drop, but the number of deaths will increase by more than 10%, due to demographic change. Numbers of breast cancer deaths are likely to rise slightly, despite falling age standardised death rates, due to an ageing population. Conclusions This work has provided estimates of early future trends, useful to service planners, and highlights the need for tobacco control, to reduce numbers of lung cancer deaths in females. The recently announced control of environmental tobacco legislation is one welcome development which should reduce lung cancer mortality in Northern Ireland. PMID:16755941

  20. The Impact of Death Education on Fear of Death and Death Anxiety Among Human Services Students.

    Human services professionals will undoubtedly work with the dying and bereaved populations at one time or other. Yet, they are poorly prepared to do so since death education, that is, lessons about the human and emotional aspects of death, its implications, and subsequent bereavement issues, is often not part of their curriculum. This nonequivalent comparison group study (N = 86) examined death fear and death anxiety among human services students before and after receiving death education using the Multidimensional Fear of Death Scale. The results showed a statistically significant decrease in death anxiety among the group of students who participated in death education compared to those who did not.

    This study examines 1970-78 South Carolina firearm fatalities utilizing vital record data. During this period, 5,808 firearm deaths, classified as accident, homicide, suicide, or undetermined, were reported with an average annual fatality rate of 23.35 deaths per 100,000 estimated population. Firearm fatalities in South Carolina were the sixth leading cause of death in 1975 and accounted for 2.9 per cent of all deaths to residents. A significant period decline in the firearm fatality rate was observed and was attributed mainly to decreases in the non-White rate. In 1978, the fatality rate for non-Whites (18.5) fell below the rate for Whites (19.1) for the first time in the years investigated. Firearm deaths represent a major community health problem and, as such, warrant attention and direct involvement by state and local health professionals. PMID:3966623

    It is intented to show two apparently antithetic poles: Sexuality and Death, in fact interpenetrate themselves, disguising the fear of death, or the desire to die, Eros' world. Different expressions of culture are analyzed, especially the one known as The Profane Time, the time for work, which is characterized by the submission to interdicts (prohibitions) and, on the other hand, the Time for Joy or The Sacred Time, characterized by the transgression of such prohibitions. Its relationship with the interdicts'violations in the sexual as well as in the death arena is analyzed in order to connect the human being's fear in the presence of the unrestraint, the overflow and the abandonment of the time established for work that would imply free sexuality. The latter is connected with some conclusions that could be considered useful in the field of Sexual Therapies, with a certain critical look at the mechanist settlement applied to those treatments.

    This report is based on a review of the present situation of the sudden infant death syndrome through the presentation of four cases studied at the Unidad de Pediatría, Hospital General de México, S.S.A. All cases were in apparent good health before death. All babies were less than ten months of age. In three cases, necropsy was not performed, and the other one did not show significant abnormalities at the post-mortem examination. A complete review of the literature was made including: historical, epidemiological, genetic, clinical and pathological aspects. Special emphasis is made on the pathophysiology of the syndrome during MOR phase of sleep and muscular hypertrophy of the lungs arteriolae suggesting chronic hypoxia which are the most relevant theories in the sudden infant death syndrome. Psychological aspects and the family management by the physician and detection of possible future victims of the syndrome are finally discussed. PMID:973858

    Cocaine availability has been increasing in Spain in the past few years. A review of all the toxicological analyses carried out at the Madrid Department of the Instituto Nacional de Toxicología, with subjects who had died of drugs from 1990 to 1992, found 533 persons who had cocaine in their blood and/or tissues; 450 (84%) deaths involved cocaine and heroin together whereas 83 (16%) deaths involved cocaine with an absence of heroin. This paper reports the circumstances, cocaine and benzoylecgonine concentrations in the blood and other toxicological findings for the two major groups of deaths where cocaine was found with an absence of heroin, i.e., possible overdose cases (35 cases) and traffic accidents (23 cases).

    Although the incidence of sudden unexpected death in infancy (SUDI) decreased markedly after campaigns to promote supine positioning during sleeping, it has remained unchanged over the last decade. Epidemiological data suggest a role for new causes such as suffocation, asphyxia, and entrapment. Health authorities in several countries have issued warnings about slings used to carry infants. However, few reports of infant deaths in slings have been published in medical journals. Our paediatric intensive care unit has admitted two infants who experienced cardiorespiratory arrest while carried in a sling. Diagnostic investigations including a post-mortem examination established asphyxia as the mechanism of death. In conclusion, baby slings may carry a risk of SUDI, either by compression of the baby into a forward-flexed position or by direct suffocation. European recommendations for the cautious use of baby slings should be disseminated to families and professionals involved in caring for infants, as done recently in Australia, Canada, and the USA.

    Near Death Experiences are those accounted by people who after being clinically dead return to life spontaneously or after reanimation. These experiences have been used traditionally to support the belief in the existence of the soul and of life after death. However, today neuroscience tries to explain these experiences from the scientific point of view, i.e. explaining them based on their brain substrates. Their resemblance to mystic experiences and to altered states of consciousness seems to indicate that they may be produced by hyperactivity of limbic structures caused by anoxia or hypercapnia.

    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.

    Death-sentenced inmates in Missouri have been integrated or "mainstreamed" into the general population of the Potosi Correctional Center since 1991. By comparing the rate of violent misconduct among these mainstreamed death-sentenced inmates with that of the life-without-parole and parole eligible inmates under fully integrated conditions of confinement, this study provides the first empirical (statistical) evaluation of this innovative alternative to segregated death row confinement. The mainstreamed death-sentenced inmates committed no inmate or staff homicides, or attempted homicides. Comparison of their rates of institutional violence revealed frequencies that were similar to those of life-without-parole inmates, and well below those of fellow inmates who were sentenced to parole eligible terms. These findings cast serious doubt on the security-driven assumptions that have typified the segregation of death-sentenced inmates and have dictated highly restrictive confinement policies for this group. A conclusion that death-sentenced inmates can be safely integrated into a general prison population has significant implications for allocation of scarce fiscal resources and correctional staff, as well as for inmate mental health, particularly given the extended tenure that death-sentenced inmates typically serve between sentencing and relief/execution.

    2007-10-01

    The purpose of this study was to test whether the developmental acquisition of a mature concept of death, that is, understanding death as a biological event, affects young children's fear of death. Ninety children between the ages of 4 and 8 participated in an interview study in which their understanding of death and their fear of death were both assessed. Levels of general anxiety were also measured via parent report. A regression analysis indicated that more mature death understanding was associated with lower levels of death fear, when age and general anxiety were controlled. These data provide some empirical support for the widely held belief that discussing death and dying in biological terms is the best way to alleviate fear of death in young children.

    Near deaths experiences are being reported with increasing frequency, but whether the constellation of factors comprising these experiences is unique to near death situations is unknown. This investigation compared near death experiences to other out-of-body experiences to determine if there are unique features associated with near death experiences. Our results indicate that there are no characteristics which are exclusive to near death situations, but our analysis of t-tests is highly suggestive of a number of distinguishing features which differentiate near death experiences from other out-of-body experiences.

    Little is known about the psychological phenomenology of death. Reported across known history and in all cultures by those who have died or been close to death, NDEs challenge objective-mechanistic models by suggesting the phenomenology of death may involve a variety of complex psychological processes. This article discusses three notable characteristics of the NDE--loss of the fear of death, psychological sequelae, and complex conscious abilities--supporting this claim. The implications these have for advancing societal understandings of death are discussed, and their pragmatic application for professions where death is frequently encountered, such as palliative care, is addressed.

    Background Unintentional, non-fire related (UNFR) carbon monoxide (CO) poisoning deaths are preventable. Surveillance of the populations most at-risk for unintentional, non-fire related (UNFR) carbon monoxide (CO) poisoning is crucial for targeting prevention efforts. Objective This study provides estimates on UNFR CO poisoning mortality in the United States and characterizes the at-risk populations. Methods We used 1999 to 2012 data to calculate death rates. We used underlying and multiple conditions variables from death records to identify UNFR CO poisoning cases. Results For this study, we identified 6136 CO poisoning fatalities during 1999 to 2012 resulting in an average of 438 deaths annually. The annual average age-adjusted death rate was 1.48 deaths per million. Fifty four percent of the deaths occurred in a home. Age-adjusted death rates were highest for males (2.21 deaths per million) and non-Hispanic blacks (1.74 deaths per million). The age-specific death rate was highest for those aged ≥85 years (6.00 deaths per million). The annual rate of UNFR CO poisoning deaths did not change substantially during the study period, but we observed a decrease in the rate of suicide and unintentional fire related cases. Conclusion CO poisoning was the second most common non-medicinal poisonings death. Developing and enhancing current public health interventions could reduce ongoing exposures to CO from common sources, such as those in the residential setting. PMID:26032660

    The purpose of this study was to determine the annual number and incidence of unintentional deaths from carbon monoxide (CO) poisonings in California and to identify specific factors that caused or contributed to the deaths. Unintentional CO deaths in California over a ten-year period (1979 to 1988) were identified from the database of the California Master Mortality File and coroners' investigation reports. Factors associated with unintentional CO deaths were determined based on the information from the investigation reports. The annual number of unintentional CO deaths varied from 27 to 58 over the ten years examined, with an average annual death incidence of 1.7 x 10(-6). Death rates were high among males and African-Americans. Alcohol appeared to be a factor in 31% of the cases. The types of combustion sources associated with unintentional CO deaths were: heating or cooking appliances; motor vehicles; charcoal grills and hibachis; small engines; and camping equipment. Factors associated with unintentional CO deaths interact in a complex way. To reduce the rate of unintentional CO deaths effectively, joint efforts involving several prevention methods are suggested.

    2015-11-01

    Nitrous oxide is an inflammable gas that gives no smell or taste. It has a history of abuse as long as its clinical use, and deaths, although rare, have been reported. We describe two cases of accidental deaths related to voluntary inhalation of nitrous oxide, both found dead with a gas mask covering the face. In an attempt to find an explanation to why the victims did not react properly to oncoming hypoxia, we performed experiments where a test person was allowed to breath in a closed system, with or without nitrous oxide added. Vital signs and gas concentrations as well as subjective symptoms were recorded. The experiments indicated that the explanation to the fact that neither of the descendents had reacted to oncoming hypoxia and hypercapnia was due to the inhalation of nitrous oxide. This study raises the question whether nitrous oxide really should be easily, commercially available. PMID:26258592

    Cells suffer necrotic death when exposed to extreme environmental conditions, adverse and excessive stimuli, or when deleterious mutations are encoded in their genetic material. Unlike apoptosis, which involves a highly regulated and elaborate network of biochemical events and cascades, necrosis has been considered generally to be a chaotic decadence process that effects the inexorable demise of cells otherwise not destined to die. This grim prospect is now slowly being overturned, mostly by exciting new findings in two simple model organisms, Caenorhabditis elegans and Drosophila melanogaster. Despite the wide spectrum of necrosis-initiating conditions, evidence is accumulating that execution of necrotic or neurodegenerative cell death may be carried out by a finite common set of mechanisms.

    Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH) founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient and support to caregivers and encourages the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. For many, cancer is synonymous with death. Fearing death is a rational response. For too long, medicine has ignored this primeval fear. Increasingly, clinicians recognize and address end-of-life issues, facing patients' and our own emotional vulnerabilities in order to connect and explore problems and fears. Listening and learning from the patient guides us as we acknowledge much of the mystery that still surrounds the dying process. Rarely is there a simple or right answer. An empathetic response to suffering patients is the best support. Support is vital in fostering the adjustment of patients. A silent presence may prove more helpful than well-meant counsel for many patients. Through an examination of eight caregiver narratives of their patients' experiences, the role of the health care provider in the dying process, particularly in regard to challenging fear, is reviewed.

    An investigation was conducted of all maternal deaths by residence which occurred in the district of Kerian, Malaysia over the 1976-1980 period. All female deaths between the years 15-45 were investigated to identify whether it was a maternal death due to obstetrical cause or otherwise. Each of the cases was investigated by the public health nurse, public health sister, and the medical officer of health before a report was made. All the maternal death reports from 1976-1980 were studied and a report compiled. The health infrastructure of Kerian district consists of 1 district hospital with 141 beds, 8 health centers, and 32 midwife clinics. The total number of deliveries in Kerian from 1976-1980 was 22,977. The hospital deliveries constituted 7040 (30.6%), the government midwives 6395 (27.8%), and traditional birth attendants (TBAs) 9505 (41.4%). The period 1976-1980 showed a decline in the various mortality rates. The infant mortality rate which is 27.11/1000 declined by 33% from 1976-1980 and toddler mortality rate declined by 37.7% from 1976-1980. The most significant decline was maternal mortality which declined from 1.89/1000 live births to 1.10/1000 live births which registered a 41.8% decline. There were a total of 35 maternal deaths registered from 1976-1980 in the district. Ethnically the Malays constituted 32 (91.4%) of all deaths and Chinese 2 (5.7%) of all deaths with Indians with 1 death (2.8%). Most of the women were from the lower income group. 19 (54.3%) of the women died at home, and 15 (42.8%) died in the hospitals. Most of the women died at gravida 6-9. Gravida 1 had 8 or 22.8% of all maternal deaths. Para 0 consisted of 9 (25.7%) of all maternal deaths and para 6 and above consisted of 11 (31.4%) of all maternal deaths. Women in the 31-40 year age group had 57.2% of the maternal deaths. PPH and PPH with retained placenta were the main causes of the maternal deaths, constituting 60% of the maternal deaths.

They are derived by similarity transforming exactly solvable 'matrix' quantum mechanics, which is recently proposed by Odake and the author [S. Odake and R. Sasaki, J. Math. Phys. 49, 053503 (2008)]. The (q-) Askey scheme of hypergeometric orthogonal polynomials of a discrete variable and their dual polynomials play a central role. The most generic solvable birth/death rates are rational functions of q{sup x} (with x being the population) corresponding to the q-Racah polynomial.

  14. Trauma therapy for death row families.

    Long, Walter C

    2011-01-01

    The family members of death row inmates undergo unique suffering that includes disenfranchised grief and intense psychological trauma. In Texas, where executions occur at a rate of 1 every 2 weeks, this class of trauma victims presumably is large, a fact that should generate public mental health concern. Yet the class remains virtually unknown to the therapeutic community. Very little has been done to address the trauma healing needs of death row families. This theoretical paper proposes that structural therapy designed to reengage attachment relationships and reempower family members' innate resources to emotionally regulate one another may provide one of the most effective means of helping this population survive trauma.

    The Centers for Disease Control and Prevention funded seven states, including Kentucky, to clarify statewide death certification practices in sudden, unexpected infant death and compare state performances with national expectations. Accurate assignment of the cause and manner of death in cases of sudden, unexpected infant death is critical for accurate vital statistics data to direct limited resources to appropriate targets, and to implement optimal and safe risk reduction strategies. The primary objectives are to (1) Compare SUID death certifications recommended by the KY medical examiners with the stated cause of death text field on the hard copy death electronic death certificates and (2) Compare KY and national SUID rates. Causes of death for SUID cases recommended by the medical examiners and those appearing on the hard copy and electronic death certificates in KY were collected retrospectively for 2004 and 2005. Medical examiner recommendations were based upon a classification scheme devised by them in 2003. Coroners hard copy death certificates and the cause of death rates in KY were compared to those occurring nationally. Eleven percent of infants dying suddenly and unexpectedly did not undergo autopsy during the study interval. The KY 2003 classification scheme for SIDS is at variance with the NICHD and San Diego SIDS definitions. Significant differences in causes of death recommended by medical examiners and those appearing on the hard copy and electronic death certificates were identified. SIDS rates increased in KY in contrast to decreasing rates nationally. Nationwide adoption of a widely used SIDS definition, such as that proposed in San Diego in 2004 as well as legislation by states to ensure autopsy in all cases of sudden unexpected infant death are recommended. Medical examiners’ recommendations for cause of death should appear on death certificates. Multidisciplinary pediatric death review teams prospectively evaluating cases before death

    2012-10-01

    Those who endorse the view that death is in some cases bad for the deceased--a view that, as I shall explain, has considerable bearing on many bioethical issues--need to address the following, Epicurean question: When is death bad for the one who dies? The two most popular answers are "before death" (priorism) and "after death" (subsequentism). Part of the support for these two views consists in the idea that a third answer, "at no time" (atemporalism), makes death unsatisfyingly different from other evils. I argue that this objection is mistaken, and that priorism and subsequentism face problems that atemporalism avoids. Moreover, I argue that if it is nonetheless insisted that we must find a time at which my death is bad for me, we can appeal to periods that begin before my death and end after my death. I end with some implications for posthumous harm.

    2014-01-01

    This study explores self-related outcomes (e.g., esteem, self-concept clarity, existential well-being) as a function of the interaction between self-reported levels of death fear and death denial. Consistent with the idea that positive existential growth can come from individuals facing, rather than denying, their mortality (Cozzolino, 2006 ), the authors observed that not fearing and denying death can bolster important positive components of the self. That is, individuals low in death denial and death fear evidenced an enhanced self that is valued, clearly conceived, efficacious, and that has meaning and purpose.

    The goal of the present study was to examine whether nurses had increased death concern and death obsession compared to non-nursing staff. A Death Concern Scale and a Death Obsession Scale, translated into Persian, were administered to 56 female Iranian nurses (55% in their 30s) and compared to 56 female hospital staff members (45% in their 30s). The two groups did not differ significantly in their scores on either scale. It is, therefore, recommended that death education programs in hospitals be given to all staff, nursing and non-nursing.

  5. Reducing deaths from pregnancy and childbirth. Asia.

    PubMed

    Pillai, G

    1993-01-01

    99% of all maternal deaths occur in the developing world, and South Asian countries account for most deaths. The causes are obstructed labor, hemorrhage, pregnancy-related hypertension (eclampsia), or unsafe abortion. The United Nation's Children's Fund estimates 340 maternal deaths for every 100,000 live births in India. In Indian rural areas, the maternal mortality rate is between 800 and 900 deaths per 100,000 live births in Bangladesh, 600; in Nepal, 830; and in Bhutan, 1710. IN comparison, the rate in the United States is 8 deaths per 100,000 live births. The technology for reducing maternal mortality has been utilized in most developed countries, as well as in parts of South Asia, in particular in Sri Lanka. The goal of the Safe Motherhood Initiative was to reduce maternal mortality by 50% by the year 2000. The immediate causes of maternal mortality include pregnancy and delivery and the management of complications such as hemorrhage, toxic and bacterial infections (sepsis), eclampsia, and obstructed labor. The poor health, nutrition, and socioeconomic status of women are the underlying causes of maternal death. One study in India found that inadequate medical treatment contributes to 36% to 47% of maternal deaths in hospitals. In India, abortion services are legal and acceptable on social, religious, and political grounds, but services are inaccessible. In Bangladesh, the availability of menstrual regulation is estimated to save 100,000 to 160,000 women from unsafe abortions each year. However, the inaccessibility of this service accounts for 700,000 unsafe abortions and 7000 maternal deaths. Gender bias in the allocation of meager food supplies results in the poor health and nutritional status of women, rendering a woman's pelvis too small, which causes obstructed labor and even death. Socioeconomic status is linked to access the family planning and health services which affect mortality and reproductive health. In Sri Lanka and Kerala, government

    In the analyses of cases of death in cold air environments, it is often of interest to determine the time required for the body of the individual to cool to ambient temperature. Usually such determinations have been based on Newton's law of cooling. This paper describes a case history in which this technique was experimentally tested and consequently abandoned in favour of a more complex biophysical model which more accurately described the thermo-physical events inherent in body cooling. This model is recommended for determination of the times required for various body parts to cool to ambient environmental temperatures.

    Although a patient whose whole brain has ceased to function may have his heart, lungs, and other organs continue to function if they are connected to the appropriate machines, the patient is still dead and the machines can be disconnected. In the future, nanotechnology, or other technology, may allow putting implants in the brainstem that can keep a patient's heart, lungs and other organs functioning, even though the whole natural brain has ceased to function. It would be useful to consider how this technology might affect the criterion of death before it is actually available.

    A new development in the dynamical behavior of elementary quantum systems is the surprising discovery that correlation between two quantum units of information called qubits can be degraded by environmental noise in a way not seen previously in studies of dissipation. This new route for dissipation attacks quantum entanglement, the essential resource for quantum information as well as the central feature in the Einstein-Podolsky-Rosen so-called paradox and in discussions of the fate of Schrödinger's cat. The effect has been labeled ESD, which stands for early-stage disentanglement or, more frequently, entanglement sudden death. We review recent progress in studies focused on this phenomenon.

    OBJECTIVE: In Sweden, a country with high standards of obstetric care, the high rate of perinatal mortality among children of immigrant women from the Horn of Africa raises the question of whether there is an association between female circumcision and perinatal death. METHOD: To investigate this, we examined a cohort of 63 perinatal deaths of infants born in Sweden over the period 1990-96 to circumcised women. FINDINGS: We found no evidence that female circumcision was related to perinatal death. Obstructed or prolonged labour, caused by scar tissue from circumcision, was not found to have any impact on the number of perinatal deaths. CONCLUSION: The results do not support previous conclusions that genital circumcision is related to perinatal death, regardless of other circumstances, and suggest that other, suboptimal factors contribute to perinatal death among circumcised migrant women.

  17. PDT: death pathways

    NASA Astrophysics Data System (ADS)

    Kessel, David

    2007-02-01

    Cellular targets of photodynamic therapy include mitochondria, lysosomes, the endoplasmic reticulum (ER) and the plasma membrane. PDT can evoke necrosis, autophagy and apoptosis, or combinations of these, depending on the PDT dose, the site(s) of photodamage and the cellular phenotype. It has been established that loss of viability occurs even when the apoptotic program is inhibited. Studies assessing effects of ER or mitochondrial photodamage, involving loss of Bcl-2 function, indicate that low-dose PDT elicited a rapid autophagic response in L1210 cells. This was attributed to the ability of autophagy to recycle photodamaged organelles, and there was partial protection from loss of viability. This effect was not observed in L1210/Atg7, where autophagy was silenced. At higher PDT doses, apoptotic cells were observed within 60 min in both cell lines, but more so in L1210. The ability of L1210 cells to undergo autophagy did not offer protection from cell death at the higher PDT dose. Previous studies had indicated that autophagy can contribute to cell death, since L1210 cells that do not undergo an initial apoptotic response often contain multiple autophagic vacuoles 24 hr later. With L1210/Atg7, apoptosis alone may account for the loss of viability at an LD 90 PDT dose.

  18. Sudden infant death syndrome.

    Adams, Stephen M; Ward, Chad E; Garcia, Karla L

    2015-06-01

    Sudden infant death syndrome (SIDS) is the sudden unexpected death of a child younger than one year during sleep that cannot be explained after a postmortem evaluation including autopsy, a thorough history, and scene evaluation. The incidence of SIDS has decreased more than 50% in the past 20 years, largely as a result of the Back to Sleep campaign. The most important risk factors relate to the sleep environment. Prone and side sleeping positions are significantly more dangerous than the supine position. Bed sharing with a parent is strongly correlated with an increased risk of SIDS, especially in infants younger than 12 weeks. Apparent life-threatening events are not a risk factor for SIDS. Parents should place infants on their backs to sleep, should not share a bed, and should avoid exposing the infant to tobacco smoke. Other risk-reducing measures include using a firm crib mattress, breastfeeding, keeping vaccinations up to date, avoiding overheating due to overbundling, avoiding soft bedding, and considering the use of a pacifier during sleep once breastfeeding is established. One consequence of the Back to Sleep campaign is a significant increase in the incidence of occipital flattening. Infants who develop a flat spot should be placed with the head facing alternating directions each time he or she is put to bed. Supervised prone positioning while the infant is awake, avoiding excessive use of carriers, and upright positioning while awake are also recommended. PMID:26034855

  19. Defining senescence and death.

    PubMed

    Thomas, Howard; Ougham, Helen J; Wagstaff, Carol; Stead, Anthony D

    2003-04-01

    This article evaluates features of leaf and flower senescence that are shared with, or are different from, those of other terminal events in plant development. Alterations of plastid structure and function in senescence are often reversible and it is argued that such changes represent a process of transdifferentiation or metaplasia rather than deterioration. It may be that the irreversible senescence of many flowers and some leaves represents the loss of ancestral plasticity during evolution. Reversibility serves to distinguish senescence fundamentally from programmed cell death (PCD), as does the fact that viability is essential for the initiation and progress of cell senescence. Senescence (particularly its timing and location) requires new gene transcription, but the syndrome is also subject to significant post- transcriptional and post-translational regulation. The reversibility of senescence must relate to the plastic, facultative nature of underlying molecular controls. Senescence appears to be cell-autonomous, though definitive evidence is required to substantiate this. The vacuole plays at least three key roles in the development of senescing cells: it defends the cell against biotic and abiotic damage, thus preserving viability, it accumulates metabolites with other functions, such as animal attractants, and it terminates senescence by becoming autolytic and facilitating true cell death. The mechanisms of PCD in plants bear a certain relation to those of apoptosis, and some processes, such as nucleic acid degradation, are superficially similar to aspects of the senescence syndrome. It is concluded that, in terms of physiological components and their controls, senescence and PCD are at best only distantly related.

  20. Stressing mitosis to death.

    PubMed

    Burgess, Andrew; Rasouli, Mina; Rogers, Samuel

    2014-01-01

    The final stage of cell division (mitosis), involves the compaction of the duplicated genome into chromatid pairs. Each pair is captured by microtubules emanating from opposite spindle poles, aligned at the metaphase plate, and then faithfully segregated to form two identical daughter cells. Chromatids that are not correctly attached to the spindle are detected by the constitutively active spindle assembly checkpoint (SAC). Any stress that prevents correct bipolar spindle attachment, blocks the satisfaction of the SAC, and induces a prolonged mitotic arrest, providing the cell time to obtain attachment and complete segregation correctly. Unfortunately, during mitosis repairing damage is not generally possible due to the compaction of DNA into chromosomes, and subsequent suppression of gene transcription and translation. Therefore, in the presence of significant damage cell death is instigated to ensure that genomic stability is maintained. While most stresses lead to an arrest in mitosis, some promote premature mitotic exit, allowing cells to bypass mitotic cell death. This mini-review will focus on the effects and outcomes that common stresses have on mitosis, and how this impacts on the efficacy of mitotic chemotherapies. PMID:24926440

    The end of the Millennium Development Goal (MDG) era was marked in 2015, and while maternal and child mortality have been halved, MGD 4 and MDG 5 are off-track at the global level. Reductions in neonatal death rates (age <1 month) lag behind those for post-neonates (age 1-59 months), and stillbirth rates (omitted from the MDGs) have been virtually unchanged. Hence, almost half of under-five deaths are newborns, yet about 80% of these are preventable using cost-effective interventions. The Every Newborn Action Plan has been endorsed by the World Health Assembly and ratified by many stakeholders and donors to reduce neonatal deaths and stillbirths to 10 per 1000 births by 2035. The plan provides an evidence-based framework for scaling up of essential interventions across the continuum of care with the potential to prevent the deaths of approximately three million newborns, mothers, and stillbirths every year. Two million stillbirths and newborns could be saved by care at birth and care of small and sick newborns, giving a triple return on investment at this key time. Commitment, investment, and intentional leadership from global and national stakeholders, including all healthcare professionals, can make these ambitious goals attainable.

    Context Stillbirth affects 1 in 160 pregnancies in the United States, equal to the number of infant deaths each year. Rates are higher than those of other developed countries and have stagnated over the past decade. There is significant racial disparity in the rate of stillbirth that is unexplained. Objective To ascertain the causes of stillbirth in a population that is diverse by race/ethnicity and geography. Design, Setting, and Participants A population-based study from March 2006 to September 2008 with surveillance for all stillbirths at 20 weeks or later in 59 tertiary care and community hospitals in 5 catchment areas defined by state and county boundaries to ensure access to at least 90% of all deliveries. Termination of a live fetus was excluded. Standardized evaluations were performed at delivery. Main Outcome Measures Medical history, fetal postmortem and placental pathology, karyotype, other laboratory tests, systematic assignment of causes of death. Results Of 663 women with stillbirth enrolled, 500 women consented to complete postmortem examinations of 512 neonates. A probable cause of death was found in 312 stillbirths (60.9%; 95% CI, 56.5%–65.2%) and possible or probable cause in 390 (76.2%; 95% CI, 72.2%–79.8%). The most common causes were obstetric conditions (150 [29.3%; 95% CI, 25.4%–33.5%]), placental abnormalities (121 [23.6%; 95% CI, 20.1%–27.6%]), fetal genetic/structural abnormalities (70 [13.7%; 95% CI, 10.9%–17.0%]), infection (66 [12.9%; 95% CI, 10.2%–16.2%]), umbilical cord abnormalities (53 [10.4%; 95% CI, 7.9%–13.4%]), hypertensive disorders (47 [9.2%; 95% CI, 6.9%–12.1%]), and other maternal medical conditions (40 [7.8%; 95% CI, 5.7%–10.6%]). A higher proportion of stillbirths in non-Hispanic black women compared with non-Hispanic white and Hispanic ones was associated with obstetric complications (43.5% [50] vs 23.7% [85]; difference, 19.8%; 95% CI, 9.7%–29.9%; P<.001) and infections (25.2% [29] vs 7.8% [28

    A study was made to determine if chickens dying from sudden death syndrome (SDS) showed any unusual behavioral characteristics during the final 12 h preceding death. Continuous video recordings were made of floor pens of 50 to 120 individually marked male broiler chickens between 3 and 10 wk of age. Behavioral data were obtained from video tapes played back following death of chickens from SDS. Analysis of the video tapes revealed no significant differences between 10 SDS chickens and their matched controls in the frequencies or proportions of time spent in each of 19 different behavioral activities. All SDS chickens exhibited a sudden attack prior to death lasting an average of 53 s and characterized by loss of balance, violent flapping, and strong muscular contractions. There was no evidence that death was preceded by a particular environmental or behavioral event. It was concluded that there were no consistent behavioral symptoms which could be used to identify SDS chickens prior to death. PMID:3684869

    The aim was to analyze the causes of sudden death in middle-aged and elderly men during manual snow removal. During snowy winter months in Zagreb, from January 2013 to January 2014, four males aged 52, 65, 72 and 81, died suddenly while manually removing snow. They were all autopsied. All of them have suffered from arterial hypertension and coronary heart disease, and one suffered from metabolic syndrome. The cause of death in two was probable malignant ventricular arrhythmia. In the third who fell down on the icy surface, consequences were cerebral contusion and neck vertebral luxation. In the fourth who fell down from the top of a 15 m tall building during snow removal, the cause of death were multiple injuries: fractures of both clavicles, ribs and vertebrae's Th5, Th6, hematothorax, cardiac contusion, hematopericardium, thoracic aorta rupture, contusions and ruptures of both lungs, rupture of the diaphragm, liver rupture, hematoperitoneum and cerebral edema. The estimated death rate in the City of Zagreb for males aged 30-64 years is 5.44/1,000,000 inhabitants, which is less than in those aged 65-85 years (40.03/1,000,000; p = 0.2269). Sudden strenuous physical effort due to manual snow removal in two non-trained persons, who have suffered from arterial hypertension and coronary heart disease, was the cause of sudden death. Manual snow removal is an important cause of sudden death, as it is a very arduous effort in non-adapted middle-aged and elderly persons. PMID:26753462

The estimated death rate in the City of Zagreb for males aged 30-64 years is 5.44/1,000,000 inhabitants, which is less than in those aged 65-85 years (40.03/1,000,000; p = 0.2269). Sudden strenuous physical effort due to manual snow removal in two non-trained persons, who have suffered from arterial hypertension and coronary heart disease, was the cause of sudden death. Manual snow removal is an important cause of sudden death, as it is a very arduous effort in non-adapted middle-aged and elderly persons.

    In the West, death studies has become a new academic area since around 1970. The driving force is the hospice movement. People now ask questions such as how to care for dying people and their relatives. Because the main clients in hospice and palliative care are cancer patients, cancer treatment and death studies are closely linked to each other. The rise of death studies is connected with the awareness of the limits of modern medicine. Medical staffs are forced to learn how to care for those patients facing death. But modern medicine has put exclusive emphasis on biomedical treatment to cure. Contemporary medicine is becoming more and more aware of the psychological and spiritual needs of the patient. Today medicine and medical education have to incorporate the perspectives from death studies, learning how human beings facing death can live a better life not only in physical terms but also in psychological, social and spiritual terms.

  9. A primatological perspective on death.

    Some questions that arise from observations of responses to dead and dying individuals by nonhuman primates are discussed, focusing on psychological issues. The phenomenon of transport and care of dead infants is reviewed, along with the consequences of the mother dying for orphaned offspring. It is argued that particular attention should be paid to how the context of a death affects individuals, for example, traumatic accidental or predation-induced death versus peaceful death following illness. Some primates kill others of their own or other species, which raises additional questions about death awareness and empathy. Observations from both the field and captivity can contribute toward a better understanding of the psychological meaning of death for primates. Some aspects of death awareness recognized by developmental psychologists might help guide research efforts in this area.

    Background Understanding children’s health after a sibling’s death and what factors may affect it is important for treatment and clinical care. This study compared children’s and their parents’ perceptions of children’s health and identified relationships of children’s age, gender, race/ethnicity, anxiety, and depression and sibling’s cause of death to these perceptions at 2 and 4 months after sibling death. Methods 64 children and 48 parents rated the child’s health “now” and “now vs before” the sibling’s death in an ICU or ER or at home shortly after withdrawal of life-prolonging technology. Children completed the Child Depression Inventory and Spence Children’s Anxiety Scale. Sibling cause of death was collected from hospital records. Results At 2 and 4 months, 45% to 54% of mothers’ and 53% to 84% of fathers’ ratings of their child’s health “now” were higher than their children’s ratings. Child health ratings were lower for: children with greater depression; fathers whose children reported greater anxiety; mothers whose child died of a chronic condition. Children’s ratings of their health “now vs before” their sibling’s death did not differ significantly from mothers’ or fathers’ ratings at 2 or 4 months. Black fathers were more likely to rate the child’s health better “now vs before” the death; there were no significant differences by child gender and cause of death in child’s health “now vs before” the death. Conclusions Children’s responses to a sibling’s death may not be visually apparent or become known by asking parents. Parents often perceive their children as healthier than children perceive themselves at 2 and 4 months after sibling death, so talking with children separately is important. Children’s perceptions of their health may be influenced by depression, fathers’ perceptions by children’s anxiety, and mother’s perceptions by the cause of sibling death.

  12. Programming stress-induced altruistic death in engineered bacteria

    2012-01-01

    Programmed death is often associated with a bacterial stress response. This behavior appears paradoxical, as it offers no benefit to the individual. This paradox can be explained if the death is ‘altruistic': the killing of some cells can benefit the survivors through release of ‘public goods'. However, the conditions where bacterial programmed death becomes advantageous have not been unambiguously demonstrated experimentally. Here, we determined such conditions by engineering tunable, stress-induced altruistic death in the bacterium Escherichia coli. Using a mathematical model, we predicted the existence of an optimal programmed death rate that maximizes population growth under stress. We further predicted that altruistic death could generate the ‘Eagle effect', a counter-intuitive phenomenon where bacteria appear to grow better when treated with higher antibiotic concentrations. In support of these modeling insights, we experimentally demonstrated both the optimality in programmed death rate and the Eagle effect using our engineered system. Our findings fill a critical conceptual gap in the analysis of the evolution of bacterial programmed death, and have implications for a design of antibiotic treatment. PMID:23169002

    Sudden unexplained death is defined by death without a conclusive diagnosis after autopsy and it is responsible for a large percentage of sudden deaths. The progressive interaction between genetics and forensics in post-mortem studies has identified inheritable alterations responsible for pathologies associated with arrhythmic sudden death. The genetic diagnosis of the deceased enables the undertaking of preventive measures in family members, many of them asymptomatic but at risk. The implications of this multidisciplinary translational medical approach are complex, requiring the dedication of a specialized team.

    Programmed cell death (PCD) is an evolutionarily conserved contributor to nervous system development. In the vertebrate peripheral nervous system, PCD is the basis of the neurotrophic theory, whereby cell death results from a surplus of neurons relative to target and competition for neurotrophic factors. In addition to stochastic cell death, PCD can be intrinsically determined by cell lineage or position and timing in both invertebrate and vertebrate central nervous systems. The underlying PCD molecular mechanisms include intrinsic transcription factor cascades and regulators of competence/susceptibility to cell death. Here, we provide a framework for understanding neural PCD from its regulation to its functions.

    Four scuba diving deaths investigated by the Forensic Medicine Unit, University of Edinburgh Medical School, are reported. The pathological investigation of such deaths requires that a detailed history of the events prior to death is obtained and that the site of the accident is fully examined with underwater photographic recording where possible. The diving suits, breathing apparatus and other diving accessories also have to be examined carefully by experts and a complete autopsy with toxicological and histological examination is essential. The causes and mechanisms of death are discussed, as are the importance of special autopsy techniques and investigations. Possible interpretative problems are highlighted.

    "Death Education" is at the same time "Life Education." For many years I have endeavored to create an awareness of the need for death education in Japan. In this paper I would like to stress the necessity of death education for the following three groups. 1. For medical personnel. Three objectives of death education: 1) Learn to understand the fears and anxieties of the patients facing death and try to reduce their excessive fears and anxieties. 2) Familiarize yourself with the ethical issues related to terminal care and try to establish a warm relationship based on trust and continue communication with the dying patient till the end. 2. For patients. 1) Be aware that the time of your life is limited and try to discover the preciousness of the remaining time. Meditate on the uniqueness of your own death. 2) Finish your unfinished business, reevaluate your human relationships and benefit from a life review therapy. 3) Remove the taboo on death, arrange your own funeral and consider the possibility of another life after death. 3. For the patient's family and friends. 1) Continue warm communication with the dying patient till the end. 2) Prepare for your own bereavement and grief. 3) Try to make your own grief process an opportunity for personal growth. When a cure is no longer possible for a dying patient, the focus of our endeavors should be loving care of the person. Death education can help us to provide better terminal care during the final stage of life.

    Drawing upon Lynne Baker's idea of the person derivatively possessing the properties of a constituting organism, I argue that even if persons aren't identical to living organisms, they can each literally die a biological death. Thus we can accept that we're not essentially organisms and can still die without having to admit that there are two concepts and criteria of death as Jeff McMahan and Robert Veatch do. Furthermore, we can accept James Bernat's definition of "death" without having to insist, as he does, that persons are identical to organisms or that persons can only die metaphorical deaths.

    1998-05-01

    This report presents an overview of statistics for the year ending in September 1997 for states in the US including births, marriages, divorces, and deaths. Provisional data for the 12 months preceding August 1996 and 1997 pertain to causes for 72 diseases for the US. Provisional data for the aforementioned years also pertains to subcategories of malignant tumors, firearm mortality, and infant mortality causes. In the 12 months ending in September 1997, there were 3,869,000 live births, 2,297,000 deaths, and a rate of natural increase of 5.9%. There were 2,326,000 marriages and 1,148,000 divorces. 3% more were married during 1996 and 1997. There were 4% more divorces granted. The death rate was 8.6 deaths/1000 population (1% lower than 1996). The infant mortality rate for the 12 months ending August 1997 was 707/100,000 live births (4% lower than the preceding year).

  1. Expressing death risk as condensed life experience and death intensity.

    PubMed

    Ioannidis, John P A

    2013-08-01

    Some risk exposures, including many medical and surgical procedures, typically carry hazards of death that are difficult to convey and appreciate in absolute terms. I propose presenting the death risk as a condensed life experience (i.e., the equivalent amount of life T that would carry the same cumulative mortality hazard for a person of the same age and sex based on life tables). For example, if the risk of death during an elective 1-hour procedure is 0.01%, and same-age and same-sex people have a 0.01% death risk over 1 month, one can inform the patient that "this procedure carries the same death risk as living 1 month of normal life." Comparative standards from other risky activities or from a person with the same disease at the same stage and same predictive profile could also be used. A complementary metric that may be useful to consider is the death intensity. The death intensity λ is the hazard function that shows the fold-risk estimate of dying compared with the reference person. The death intensity can vary substantially for different phases of the event, operation, or procedure (e.g., intraoperative, early postoperative, late postoperative), and this variability may also be useful to convey. T will vary depending on the time window for which it is computed. I present examples for calculating T and λ using literature data on accidents, ascent to Mount Everest, and medical and surgical procedures.

    The concept of brain death was formulated in 1968 in the landmark report A Definition of Irreversible Coma. While brain death has been widely accepted as a determination of death throughout the world, many of the controversies that surround it have not been settled. Some may be rooted in a misconstruction about the history of brain death. The concept evolved as a result of the convergence of several parallel developments in the second half of the 20th century including advances in resuscitation and critical care, research into the underlying physiology of consciousness, and growing concerns about technology, medical futility, and the ethics of end of life care. Organ transplantation also developed in parallel, and though it clearly benefited from a new definition of death, it was not a principal driving force in its creation. Since 1968, the concept of brain death has been extensively analyzed, debated, and reworked. Still there remains much misunderstanding and confusion, especially in the general public. In this comprehensive review, I will trace the evolution of the definition of brain death as death from 1968 to the present, providing background, history and context. PMID:24930367

    OBJECTIVES To determine whether the increasing fall death rate among people aged 65 and older is due in part to temporal changes in recording the underlying cause of death. DESIGN Analyses of multiple cause of death data using the online Centers for Disease Control and Prevention Wide-ranging ON-line Data for Epidemiologic Research system, which uses the National Center for Health Statistics’ Multiple Cause of Death data set. SETTING United States, 1999 to 2010. PARTICIPANTS People aged 65 and older with a fall listed on their death record as the underlying or a contributing cause of death. MEASUREMENTS Circumstances and contributing causes off all deaths—records listing International Classification of Diseases, Tenth Revision, codes W00 to W19 as the underlying cause of death—and underlying causes for records with falls as a contributing cause were examined. Joinpoint regression analysis was used to assess trends in the proportion of fall and fall-associated deaths to total deaths for 1999 to 2010. RESULTS In 2010, there were 21,649 fall deaths and 5,402 fall-associated deaths among people aged 65 and older; 48.7% of fall deaths involved a head injury. Approximately half the fall death records included diseases of the circulatory system as contributing causes. From 1999 to 2010, there was a trend toward more-specific reporting of falls circumstances, although total deaths remained unchanged. The proportion of fall deaths to total deaths increased 114.3%, and that of fall-associated deaths to total deaths increased 43.1%. CONCLUSION The reasons behind the increasing older adult fall death rate deserve further investigation. Possible contributing factors include changing trends in underlying chronic diseases and better reporting of falls as the underlying cause of death. PMID:24617970

  5. Kinetics of Thermal Death of Bacteria

    Moats, William A.

    1971-01-01

    Experimental observations on thermal injury and death of bacteria in the stationary phase can be explained by assuming that death results from inactivation of (XL) of N critical sites. It is assumed: (i) that inactivation of individual sites occurs at random and follows first-order kinetics, (ii) that the critical sites are identical and of equal heat resistance, and (iii) the bacterial population is homogeneous in heat resistance. A method is described for calculating k (the rate constant for inactivation of individual sites), N (sites per cell), and XL (the number which must be inactivated to cause death under the experimental conditions used) from experimental data. Theoretical curves calculated by using this model are identical with experimental curves, providing support for the assumptions used. Calculated values of N and XL were 130 and 21.7 for Pseudomonas viscosa and 175 and 2.7 for Salmonella anatum. There is considerable uncertainty in the absolute values of N, but they are probably > 100. It is predicted that XL will vary depending on the recovery medium used after heating. This theory is consistent with all experimental observations on thermal injury and death of bacteria. PMID:4925119

    Objective—This study describes epidemiologic patterns of mortality due to suicide, homicide, and war for the world in order to serve as a benchmark against which to measure future progress and to raise awareness about violence as a global public health problem. Setting—The world and its eight major regions. Method—Data were derived from The Global Burden of Disease series and the US National Center for Health Statistics to estimate crude rates, age adjusted rates, sex rate ratios, and the health burden for suicide, homicide, and war related deaths for the world and its eight major regions in 1990. Results—In 1990, an estimated 1 851 000 people died from violence (35.3 per 100 000) in the world. There were an estimated 786 000 suicides. Overall suicide rates ranged from 3.4 per 100 000 in Sub-Saharan Africa to 30.4 per 100 000 in China. There were an estimated 563 000 homicides. Overall homicide rates ranged from 1.0 per 100 000 in established market economies to 44.8 per 100 000 in Sub-Saharan Africa with peaks among males aged 15–24 years old, and among females aged 0–4 years old. There were an estimated 502 000 war related deaths with peaks in rates for both sexes among people aged 0–4, 15–29, and 60–69 years old. Conclusion—The number of violence related deaths in the world is unacceptably high. Coordinated prevention and control efforts are urgently needed. PMID:11428556

    Near-death experiences (NDE) are lucid events that take place when a person is so physically compromised that he would die if its condition does not improve. He is unconscious, without heartbeats and breath, and with a flat-line electroencephalogram. NDE may include some of the following elements: Out of the body experiences or separation of consciousness from the physical body, increase in sensory perception and intense emotions, travel into or through a tunnel, encounter with a brilliant light and mystical beings, deceased relatives or friends, a sense of alteration in time and space, visualization of unworldly realms and a special knowledge, encounter with a barrier or boundary, and a return to the body, either voluntary or involuntary. The fact that children NDE are similar to adult NDE is an evidence that these experiences are real and not due to pre-existing beliefs, cultural influences or previous experiences in the present life. The characteristics of NDE are similar worldwide. No evidence supports the physiological, psychological, neurochemical, and neuroanatomical hypothesis proposed to explain the NDE. Multifactorial models, based on the combination of all of them (brain anoxia or hypoxia, release of serotonin, endorphins and ketamine-like compounds) have also been proposed. Although physiological, psychological, and socio-cultural factors could interact in the NDE, the hypothesis proposed consist essentially in unsupported speculations about what might be happening during the NDE.

    Tower, John

    2015-01-01

    Programmed cell death (PCD) pathways, including apoptosis and regulated necrosis, are required for normal cell turnover and tissue homeostasis. Mis-regulation of PCD is increasingly implicated in aging and aging-related disease. During aging the cell turnover rate declines for several highly-mitotic tissues. Aging-associated disruptions in systemic and inter-cell signaling combined with cell-autonomous damage and mitochondrial malfunction result in increased PCD in some cell types, and decreased PCD in other cell types. Increased PCD during aging is implicated in immune system decline, skeletal muscle wasting (sarcopenia), loss of cells in the heart, and neurodegenerative disease. In contrast, cancer cells and senescent cells are resistant to PCD, enabling them to increase in abundance during aging. PCD pathways limit life span in fungi, but whether PCD pathways normally limit adult metazoan life span is not yet clear. PCD is regulated by a balance of negative and positive factors, including the mitochondria, which are particularly subject to aging-associated malfunction. PMID:25862945

    Poly-ADP-ribose polymerase-1 (PARP-1)'s roles in the cell span from maintaining life to inducing death. The processes PARP-1 is involved in include DNA repair, DNA transcription, mitosis, and cell death. Of PARP-1's different cellular functions, its role in cell death is of particular interest to designing therapies for diseases. Genetic deletion of PARP-1 revealed that PARP-1 overactivation underlies cell death in 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 understanding mechanisms downstream of PARP-1 overactivation. Recent evidence shows that poly-ADP ribose (PAR) polymer itself can act as a cell death effector downstream of PARP-1. 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 present evidence and questions raised by these recent findings, and summarize the proposed mechanisms by which PARP-1 overactivation kills. It is evident that further understanding of parthanatos opens up new avenues for therapy in ameliorating diseases related to PARP-1 overactivation. PMID:19273119

    Objectives .- To compare the mortality experience of 112 justices of the US Supreme Court with that expected in the general population. To identify variables associated with mortality within this cohort. Background .- Supreme Court justices are a select occupational cohort. High socio-economic status, advanced education, lifetime appointment, and the healthy worker effect suggest lower mortality. Sedentary work, stress, and a tendency to work beyond typical retirement age may attenuate this. Methods .- Standardized mortality ratios compare the observed mortality rates of justices with those expected in age- and sex-matched contemporary general populations. Poisson regression analyzes variables associated with mortality within the cohort. Results .- From 1789 to 2013, 112 justices (108 male) contributed 2,355 person-years of exposure. Mean age (standard deviation) at appointment was 53.1 years (6.7); at retirement 69.7 years (9.9); at death (n = 100) 74.4 years (10.3); and at end of the study for those alive (n = 12) 72.1 years (11.8). Standardized mortality ratios (95% ci) were: overall 0.87 (0.70-1.05); prior to 1950 0.92 (0.61-1.33); and from 1950 to 2013 0.66 (0.42-0.99). Variables in the final Poisson model and their associated mortality rate ratios (95% ci) were: age 1.06 (1.03-1.09); calendar year 0.99 (0.99-1.00); active status 0.41 (0.25-0.68); career length 1.04 (1.01-1.07); and chief justice 1.08 (0.59-1.84). Conclusions .- Supreme Court mortality was lower than that of the general population in the period from 1950 to the present, but was on par prior to 1950. Increasing age and career length were associated with greater mortality, while active status and later calendar year with lower. These results may add to a body of knowledge that may help to develop or refine models of mortality risk in increasingly aged working populations.

  17. Death row inmate characteristics, adjustment, and confinement: a critical review of the literature.

    PubMed

    Cunningham, Mark D; Vigen, Mark P

    2002-01-01

    This article reviews and summarizes research on death row inmates. The contributions and weaknesses of death row demographic data, clinical studies, and research based on institutional records are critiqued. Our analysis shows that death row inmates are overwhelmingly male and disproportionately Southern. Racial representation remains controversial. Frequently death row inmates are intellectually limited and academically deficient. Histories of significant neurological insult are common, as are developmental histories of trauma, family disruption, and substance abuse. Rates of psychological disorder among death row inmates are high, with conditions of confinement appearing to precipitate or aggravate these disorders. Contrary to expectation, the extant research indicates that the majority of death row inmates do not exhibit violence in prison even in more open institutional settings. These findings have implications for forensic mental health sentencing evaluations, competent attorney representation, provision of mental health services, racial disparity in death sentences, death row security and confinement policies, and moral culpability considerations. Future research directions on death row populations are suggested.

  18. Uniformity in brain death criteria.

    Despite well-described international variabilities in brain death practices, de facto there already exists a minimum international clinical standard for the diagnosis of brain death. This remains rooted in the Harvard criteria and based on the characteristics of a permanently nonfunctioning brain. Medicine is evolving toward a single unified determination of death based on the cessation of brain function subsequent to catastrophic brain injury or circulatory arrest. Clarity in lexicon could be established, including movement toward functional definitions and away from anatomically based terms such as cardiac and brain death that erroneously imply death of the organ. The cessation of clinical functions of the brain that will not resume is determined by the absence of capacity for consciousness, centrally mediated motor responses, brainstem reflexes, and capacity to breathe. A known proximate cause and the absence of confounding or reversible conditions must be confirmed. Regional medical, legal, cultural, religious, or socioeconomic factors may require testing beyond this minimal clinical standard. PMID:25839725

    The case of Jahi McMath has reignited a discussion concerning how society should define death. Despite pronouncing McMath brain dead based on the American Academy of Neurology criteria, the court ordered continued mechanical ventilation to accommodate the family's religious beliefs. Recent case law suggests that the potential for a successful challenge to the neurologic criteria of death provisions of the Uniform Determination of Death Act are greater than ever in the majority of states that have passed religious freedom legislation. As well, because standard ethical claims regarding brain death are either patently untrue or subject to legitimate dispute, those whose beliefs do not comport with the brain death standard should be able to reject it.

    Objectives To explore the experiences, acceptance, and effects of conducting facility death review (FDR) of maternal and neonatal deaths and stillbirths at or below the district level in Bangladesh. Methods This was a qualitative study with healthcare providers involved in FDRs. Two districts were studied: Thakurgaon district (a pilot district) and Jamalpur district (randomly selected from three follow-on study districts). Data were collected between January and November 2011. Data were collected from focus group discussions, in-depth interviews, and document review. Hospital administrators, obstetrics and gynecology consultants, and pediatric consultants and nurses employed in the same departments of the respective facilities participated in the study. Content and thematic analyses were performed. Results FDR for maternal and neonatal deaths and stillbirths can be performed in upazila health complexes at sub-district and district hospital levels. Senior staff nurses took responsibility for notifying each death and conducting death reviews with the support of doctors. Doctors reviewed the FDRs to assign causes of death. Review meetings with doctors, nurses, and health managers at the upazila and district levels supported the preparation of remedial action plans based on FDR findings, and interventions were planned accordingly. There were excellent examples of improved quality of care at facilities as a result of FDR. FDR also identified gaps and challenges to overcome in the near future to improve maternal and newborn health. Discussion FDR of maternal and neonatal deaths is feasible in district and upazila health facilities. FDR not only identifies the medical causes of a maternal or neonatal death but also explores remediable gaps and challenges in the facility. FDR creates an enabled environment in the facility to explore medical causes of deaths, including the gaps and challenges that influence mortality. FDRs mobilize health managers at upazila and district

    Things are not always what they seem at first sight. One should always be on the watch for more than presents itself as the main issue in the investigation of crime. Whenever a person dies at the scene of accident, it is inferred that the accident caused the death. But that does not mean that the inference is correct. A person who was suspected to have met with a road traffic accident after autopsy turned out to be a case of sudden natural death due to acute haemorrhagic pancreatitis. The case is reported as it is of medico-legal interest because a natural death appeared to be due to a traffic accident.

  2. Modeling causes of death: an integrated approach using CODEm

    PubMed Central

    2012-01-01

    Background Data on causes of death by age and sex are a critical input into health decision-making. Priority setting in public health should be informed not only by the current magnitude of health problems but by trends in them. However, cause of death data are often not available or are subject to substantial problems of comparability. We propose five general principles for cause of death model development, validation, and reporting. Methods We detail a specific implementation of these principles that is embodied in an analytical tool - the Cause of Death Ensemble model (CODEm) - which explores a large variety of possible models to estimate trends in causes of death. Possible models are identified using a covariate selection algorithm that yields many plausible combinations of covariates, which are then run through four model classes. The model classes include mixed effects linear models and spatial-temporal Gaussian Process Regression models for cause fractions and death rates. All models for each cause of death are then assessed using out-of-sample predictive validity and combined into an ensemble with optimal out-of-sample predictive performance. Results Ensemble models for cause of death estimation outperform any single component model in tests of root mean square error, frequency of predicting correct temporal trends, and achieving 95% coverage of the prediction interval. We present detailed results for CODEm applied to maternal mortality and summary results for several other causes of death, including cardiovascular disease and several cancers. Conclusions CODEm produces better estimates of cause of death trends than previous methods and is less susceptible to bias in model specification. We demonstrate the utility of CODEm for the estimation of several major causes of death. PMID:22226226

    To describe geographical variation in breast cancer mortality over time, we analysed breast cancer mortality data from three retrospective national surveys on causes of death in recent decades in China. We first calculated the age-standardized mortality rate (ASMR) for each of the 31 provinces in mainland China stratified by survey period (1973–1975, 1990–1992 and 2004–2005). To test whether the geographical variation in breast cancer mortality changed over time, we then estimated the rate ratio (RR) for the aggregated data for seven regions and three economic zones using generalized linear models. Finally, we examined the correlation between mortality rate and several macro-economic measures at the provincial level. We found that the overall ASMR increased from 2.98 per 100,000 in 1973–1975 to 3.08 per 100,000 in 1990–1992, and to 3.85 per 100,000 in 2004–2005. Geographical variation in breast cancer mortality also increased significantly over time at the regional level (p = 0.002) but not at the economic zone (p = 0.089) level, with RR being generally lower for Western China (Northwest and Southwest) and higher in Northeast China over the three survey periods. These temporal and spatial trends in breast cancer mortality were found to be correlated with per capita gross domestic product, number of hospitals and health centres’ beds per 10,000 population and number of practicing doctors per 10,000 population, and average number of live births for women aged 15–64. It may be necessary to target public health policies in China to address the widening geographic variation in breast cancer mortality, and to take steps to ensure that the ease of access and the quality of cancer care across the country is improved for all residents.

  4. Commercial fishing industry deaths - forensic issues.

    PubMed

    Byard, Roger W

    2013-04-01

    The commercial fishing industry has one of the highest injury and mortality rates of all occupational areas. This results from the nature of the work involving vessels often manned by only a few individuals who are working with heavy-duty equipment in dangerous environments at all hours. Economic pressures may force inappropriately geared vessels to operate further out to sea than is safe. Deaths result from a wide variety of situations involving vessel loss, falls overboard, fire and explosions, cable entanglements and gas exposure. Autopsies are often difficult as there are no diagnostic features of either drowning or hypothermia and features may be obscured by putrefaction and postmortem animal predation. The forensic implications of deaths in the fishing industry are reviewed.

    In October 2006, four deaths occurred in Israel shortly after influenza immunization, resulting in a temporary halt to the vaccination campaign. After an epidemiologic investigation, the Ministry of Health concluded that these deaths were not related to the vaccine itself and the campaign resumed; however, vaccine uptake was markedly reduced. Estimates of true background mortality in this high-risk population would aid in public education and quell unnecessary concerns regarding vaccine safety. We used data from a large HMO to estimate mortality in influenza vaccine recipients aged 55 and over during four consecutive winters (2003, 2004, 2005 and 2006). Date of immunization was ascertained from patient treatment files, vital status through Israeli National Insurance Institute data. We calculated crude death rates within 7, 14 and 30 days of influenza immunization, and used a Cox Proportional Hazards Model to estimate the risk of death within 14 days of vaccination, adjusting for age and comorbid conditions (age over 75, history of diabetes or cardiovascular disease, status as homebound patient) in 2006. The death rate among influenza vaccine recipients ranged from 0.01 to 0.02% within 7 days and 0.09-0.10% at 30 days. Influenza immunization was associated with a decreased risk of death within 14 days after adjustment for comorbidities (Hazard ratio, 0.33, 95% CI, 0.18-0.61). Our findings support the assumption that influenza vaccination is not associated with increased risk of death in the short term.

    The Office of the Chief Medical Examiner of Maryland recorded a total of 149 drug abuse deaths of teenagers aged 13-19 years between 1991 and 2006. Of these deaths, 96 (64.4%) were caused by the use of narcotic drugs only, 29 (19.5%) by both narcotics and cocaine, four (2.7%) by both narcotics and methylenedioxymethamphetamine, six (4.0%) by cocaine only, and 14 (9.4%) by volatile substances (e.g., butane, Freon, nitrous oxide, and propane). The annual death rate from drug abuse for teenagers increased from 1.4 deaths per 100,000 population in 1991 to 2.7 deaths per 100,000 population in 2006 (chi-square test for time trend, p<0.01). The increase in teenager drug abuse deaths occurred in 1999 and since has remained at a higher rate. Further analysis revealed that the increase in drug abuse deaths was attributable to a large degree to narcotic drugs, particularly heroin/morphine and methadone, and was confined to teenagers residing in the suburban and rural areas.

    2002-08-01

    Although fear of death has been linked to hypochondriasis, the relationship of this fear to the disorder has received little study. To address this deficiency, we administered a fear of death scale along with measures of hypochondriasis, including the Whiteley Index and Somatic Symptom Inventory, to 162 general medical outpatients. Partial correlations, controlling for age, between the fear of death scale and both the Whiteley Index and Somatic Symptom Inventory were strongly positive. A factor analysis of the fear of death scale yielded three dimensions-fear of dying, loss of meaning, and fear of separation-that were also highly correlated with hypochondriasis. Fear of death and hypochondriasis showed comparable relationships to age and gender as well as to personality dimensions measured by the NEO Five-Factor Inventory. Fear of death appears to be an integral part of hypochondriasis. Its presence lends support to three models of hypochondriasis-the perceptual, existential, and interpersonal-that correspond to the dimensions of fear of death.

    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. PMID:16200328

    Objective To identify gender differences in violent deaths in terms of incidence, circumstances, and methods of death. Design Analysis of surveillance data. Setting North Carolina, a state of 8.6 million residents on the eastern seaboard of the US. Subjects 1674 North Carolina residents who died from violence in the state during 2004. Methods Information on violent deaths was collected by the North Carolina Violent Death Reporting System using data from death certificates, medical examiner reports, and law enforcement agency incidence reports. Results Suicide and homicide rates were lower for females than males. For suicides, females were more likely than males to have a diagnosis of depression (55% v 36%), a current mental health problem (66% v 42%), or a history of suicide attempts (25% v 13%). Firearms were the sole method of suicide in 65% of males and 42% of females. Poisonings were more common in female than male suicides (37% v 12%). Male and female homicide victims were most likely to die from a handgun or a sharp instrument. Fifty seven percent of female homicides involved intimate partner violence, compared with 13% of male homicides. Among female homicides involving intimate partner violence, 78% occurred in the woman's home. White females had a higher rate of suicide than African‐American females, but African‐American females had a higher rate of homicide than white females. Conclusions The incidence, circumstances, and methods of fatal violence differ greatly between females and males. These differences should be taken into account in the development of violence prevention efforts. PMID:17170164

    2003-01-01

    Aim: To assess the value of maintaining a death register in a general practice with particular reference to monitoring quality of care. Design of study: Observational study. Setting: Inner London general practice. Method: The practice maintained a manual death register, retained medical records of all deceased patients, and requested information on cause of death from health authorities and coroners for 15 years. Main outcome measures: Number and causes of deaths; 3 yearly age standardised death rates; proportion of deaths formally notified to the practice; place of death; source of cause of death information. Results: During the study period 578 patients died. Practice age standardised death rates fell significantly from 35.59 to 27.12/1000. 498 (86.2%) deaths were formally notified to the practice, 392 within 7 days of death. Of 143 deaths reported to the coroner, only 45 coroners' reports were received. 360 (64.1%) died in hospital, 139 (24.8%) at home, and 38 (6.8%) in a hospice. Death certificate cause of death information was obtained from patients' records in 33.6% (n=194) of cases and from health authority sources for 50% (n=289). The pattern of ascertained causes of deaths was similar to the national pattern. Conclusion: A death register can examine trends in practice deaths by age and place of death and comparisons undertaken with nationally published mortality data. An accurate picture of cause of death cannot be generated from routine data flows alone. There is delay in informing GPs of patient deaths. Meaningful and timely monitoring of deaths cannot be undertaken by individual practices. National Statistics should provide routine analysis of GP death certificate information. PMID:14532364

    1964-01-01

    The kinetics of death of Bacillus stearothermophilus spores (FS 7954) suspended in phosphate buffer (pH 7) were studied over a temperature range of 127.2 to 143.8 C and exposure times of 0.203 to 4.150 sec. These short exposure were achieved by use of a tubular flow reactor in which a suspension of spores was injected into a hot flowing stream at the entrance of the reactor. Thermal equilibria of the suspension with the hot stream was achieved within 0.0006 sec. After flow through a fixed length of reactor, the stream containing the spores was cooled by flash vaporization and then assayed for viable count. The death rate data were fitted by a logarithmic expression. However, logarithmic death rate was only approximated in the tail or high-kill regions of exposure. Death rate constants obtained from this portion of the data were found to correlate by Arrhenius as well as Absolute Reaction Rate Theory relationships. Thermal-death time curves were found to correlate the data rather poorly. The activation energy and frequency constant for an Arrhenius relationship fit of the data were found to be 83.6 kcal/gmole and 1047.2 min-1, respectively. The standard enthalpy and entropy changes for an Absolute Reaction Rate Theory relationship fit of the data were found to be 84.4 kcal/gmole and 157 cal/gmole-K, respectively. PMID:14215978

    Scarce information about the epidemiology of historical influenza pandemics in South America prevents complete understanding of pandemic patterns throughout the continent and across different climatic zones. To fill gaps with regard to spatiotemporal patterns of deaths associated with the 1918 influenza pandemic in Chile, we reviewed archival records. We found evidence that multiple pandemic waves at various times of the year and of varying intensities occurred during 1918-1921 and that influenza-related excess deaths peaked during July-August 1919. Pandemic-associated mortality rates were elevated for all age groups, including for adults >50 years of age; elevation from baseline was highest for young adults. Overall, the rate of excess deaths from the pandemic was estimated at 0.94% in Chile, similar to rates reported elsewhere in Latin America, but rates varied ≈10-fold across provinces. Patterns of death during the pandemic were affected by variation in host-specific susceptibility, population density, baseline death rate, and climate.

    A retrospective survey was undertaken of all deaths in children under 5 in the borough of Wolverhampton over the years 1976-82. Cause of death was classified in terms of preventability and possibly preventable deaths studied in more detail. Birth weight in the study group was significantly lower than that of the local population; there was no difference in ethnic origin, but there were significantly more Asian girls than Asian boys. The association between potentially preventable death and various socioeconomic indicators in the electoral wards in the borough was investigated. A significant association was found between mortality and overcrowding, lack of household amenities, unemployment, lack of car ownership, and households where the head was born in the new Commonwealth or Pakistan.

    Most reported near-death experiences include profound feelings of peace, joy, and cosmic unity. Less familiar are the reports following close brushes with death of experiences that are partially or entirely unpleasant, frightening, or frankly hellish. While little is known about the antecedents or aftereffects of these distressing experiences, there appear to be three distinct types, involving (1) phenomenology similar to peaceful near-death experiences but interpreted as unpleasant, (2) a sense of nonexistence or eternal void, or (3) graphic hellish landscapes and entities. While the first type may eventually convert to a typical peaceful experience, the relationship of all three types to prototypical near-death experiences merits further study. The effect of the distressing experience in the lives of individuals deserves exploration, as the psychological impact may be profound and long-lasting.

    Programmed cell death in protists does not seem to make sense at first sight. However, apoptotic markers in unicellular organisms have been observed in all but one of the six/eight major groups of eukaryotes suggesting an ancient evolutionary origin of this regulated process. This review summarizes the available data on apoptotic markers in non-opisthokonts and elucidates potential functions and evolution of programmed cell death. A newly discovered family of caspase-like proteases, the metacaspases, is considered to exert the function of caspases in unicellular organisms. Important results on metacaspases, however, showed that they cannot be always correlated to the measured proteolytic activity during protist cell death. Thus, a major challenge for apoptosis research in a variety of protists remains the identification of the molecular cell death machinery.

  12. Actual innocence: is death different?

    PubMed

    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.

    Spontaneous and reflex movements have been described in brain death and these unusual movements might cause uncertainties in diagnosis. In this study we evaluated the presence of spinal reflexes in patients who fulfilled the criteria for brain death. Thirty-two (22 %) of 144 patients presented unexpected motor movements spontaneously or during examinations. These patients exhibited the following signs: undulating toe, increased deep tendon reflexes, plantar responses, Lazarus sign, flexion-withdrawal reflex, facial myokymia, neck-arm flexion, finger jerks and fasciculations. In comparison, there were no significant differences in age, sex, etiology of brain death and hemodynamic laboratory findings in patients with and without reflex motor movement. Spinal reflexes should be well recognized by physicians and it should be born in mind that brain death can be determined in the presence of spinal reflexes.

    Psychiatrists should refrain from treating mentally ill prisoners on death row in order to restore their "competency to be executed." Such "treatment" renders them double agents, in the service of the state as well as the prisoner. Participation in an act that will bring about a prisoner's death is expressly forbidden by the AMA Code of Ethics. It recalls the behavior of Nazi physicians, who used their professional skills not to heal but to kill.

    Death dogged Vincent's footsteps throughout his life, and formed a core component of his unconscious fantasy system. It cast a lugubrious shadow over all of his undertakings--he found little joy and less love in life. It found its way onto his canvases, both directly--the grinning death's head--and indirectly. It found expression in his portrayals of sowers and reapers, in his representations of trees--especially the highly symbolic treatments of cypresses--in the menacing crows hovering over storm-darkened fields of wheat, and finally in the images of Christ, suffering and dead, held in the embrace of a loving and grieving mother. If death was a bottomless pit that haunted him with its terrors, it was also a siren song that drew him ever closer to his destiny, ever closer to the edge of the pit. The power of that attraction lies in his identification with the dead Vincent whose place he had taken and whose name he bore. It was through that identification, and through the passageway of suffering and death that he would surcease in the arms of a loving and accepting mother whose warm embrace he had sought throughout his odyssey, but in vain. It was to be gained only in and through death. It was only through death that he would find rest from his pain and would gain the heavenly reward of his suffering in eternal love and bliss.

    Epilepsy is a common chronic neurological disorder characterized by seizures. Mortality is significantly increased in patients with epilepsy. Sudden unexpected death in epilepsy (SUDEP) is the most common seizure-related category of death. A retrospective study of forensic autopsy cases from 2007 to 2009 at the Office of the Chief Medical Examiner (OCME) yielded a total of 104 sudden unexpected deaths directly or indirectly caused by an epilepsy/seizure disorder in the State of Maryland. Of these deaths, 74 cases met a general accepted definition of SUDEP. The age of SUDEP individuals ranged from 14 to 63 with the majority of subjects in the ages between 21 and 50 years (58 cases, 78.4%). Males were slightly more likely than females to die of SUDEP (male:female=1.5:1 based on the rate). The onset age of epilepsy was documented in 47.3% of cases (35/74) based on investigation and medical records. Of the 35 cases, 12 subjects had early onset epilepsy (onset ages 1-15 years) and 20 subjects had duration of epilepsy for more than 10 years. The majority of deaths (61 of the 74 cases, 82.4%) were unwitnessed. Death scene investigation showed that 71 deaths (95.9%) occurred inside their residence with 50 subjects (70.4%) found either in bed or on the bedroom floor near the bed. Forty-three out of 74 cases (58.1%) showed neuropathological lesions. Per history, 50 subjects were reported as being on anti-epileptic drugs (AEDs). However, postmortem toxicological analysis revealed that only 26 subjects (35.1%) had detectable AEDs. Of the 74 cases, seizure disorder or epilepsy was listed as primary cause of death in 66 cases and the term of SUDEP as official cause of death in only 8 cases. This report focuses on the characteristics of death scene investigation and postmortem examination findings of SUDEP cases.

    Sudden cardiac death is still the largest cause of natural death in western countries, especially in patients with coronary artery disease and in those who have already experienced an episode of resuscitated out-of-hospital cardiac arrest or ventricular tachycardia. Prevention of arrhythmia recurrences (i.e. secondary prevention) in these patients remains a challenge for the cardiologist. To date no studies have demonstrated that drug therapy can be of some value in preventing arrhythmia recurrences or sudden death in these patients, and only cardioverter-defibrillator (ICD) implantation resulted effective in reducing mortality rate. It remains, however, to be defined which patients who survived an out-of-hospital cardiac arrest or who already experienced a sustained ventricular tachycardia could benefit the most from an ICD, but to date no invasive or non-invasive tests have proven to be effective for this stratification. Vaughan-Williams class II and III drugs could be of some value in reducing tachycardia cycle length thus increasing antitachycardia pacing efficacy and reducing ICD shocks.

    Suicide and other self-directed violence deaths are likely grossly underestimated, reflecting inappropriate classification of many drug intoxication deaths as accidents or unintentional and heterogeneous ascertainment and coding practices across states. As the tide of prescription and illicit drug-poisoning deaths is rising, public health and research needs would be better satisfied by considering most of these deaths a result of self-intoxication. Epidemiologists and prevention scientists could design better intervention strategies by focusing on premorbid behavior. We propose incorporating deaths from drug self-intoxication and investigations of all poisoning deaths into the National Violent Death Reporting System, which contains misclassified homicides and undetermined intent deaths, to facilitate efforts to comprehend and reverse the surging rate of drug intoxication fatalities.

    There is an increased risk of sudden cardiac death (SCD) and sudden cardiac arrest (SCA), in African Americans, the basis of which is likely multifactorial. African Americans have higher rates of traditional cardiac risk factors including hypertension, left ventricular hypertrophy, diabetes, coronary heart disease, and heart failure. There are also significant disparities in health care delivery. While these factors undoubtedly affect health outcomes, there is also growing evidence that genetics may have a significant impact as well. In this paper, we discuss data and hypotheses in support of both sides of the controversy around racial differences in SCD/SCA.

    Sudden cardiac death accounts for approximately 50% of all deaths attributed to cardiovascular disease in the United States. It is most commonly associated with coronary artery disease and can be its initial manifestation or may occur in the period after an acute myocardial infarction. Decreasing the rate of sudden cardiac death requires the identification and treatment of at-risk patients through evidence-based pharmacotherapy and interventional strategies aimed at primary and secondary prevention. For this review, we searched PubMed for potentially relevant articles published from January 1, 1970, through March 1, 2014, using the following key search terms: sudden cardiac death, ischemic heart disease, coronary artery disease, myocardial infarction, and cardiac arrest. Searches were enhanced by scanning bibliographies of identified articles, and those deemed relevant were selected for full-text review. This review outlines various mechanisms for sudden cardiac death in the setting of coronary artery disease, describes risk factors for sudden cardiac death, explores the management of cardiac arrest, and outlines optimal practice for the monitoring and treatment of patients after an acute ST-segment elevation myocardial infarction to decrease the risk of sudden death.

    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.

    AKI is pathologically characterized by sublethal and lethal damage of renal tubules. Under these conditions, renal tubular cell death may occur by regulated necrosis (RN) or apoptosis. In the last two decades, tubular apoptosis has been shown in preclinical models and some clinical samples from patients with AKI. Mechanistically, apoptotic cell death in AKI may result from well described extrinsic and intrinsic pathways as well as ER stress. Central converging nodes of these pathways are mitochondria, which become fragmented and sensitized to membrane permeabilization in response to cellular stress, resulting in the release of cell death-inducing factors. Whereas apoptosis is known to be regulated, tubular necrosis was thought to occur by accident until recent work unveiled several RN subroutines, most prominently receptor-interacting protein kinase-dependent necroptosis and RN induced by mitochondrial permeability transition. Additionally, other cell death pathways, like pyroptosis and ferroptosis, may also be of pathophysiologic relevance in AKI. Combination therapy targeting multiple cell-death pathways may, therefore, provide maximal therapeutic benefits. PMID:24925726

  7. Death, mourning, and medical progress.

    PubMed

    Callahan, Daniel

    2009-01-01

    A number of changes can be observed in the way people are coming to think about death, mourning, and medical progress. The palliative care movement was initiated some 30 years ago to respond to widespread ignorance or neglect of pain relief for the dying, which was then coming to public attention and becoming a key part of the nascent hospice movement. Yet if an important feature of the latter movement was acceptance of the reality of death, in recent years there has emerged a blending of clinical treatment and hospice care, a kind of compromise with the idea of death as an inevitability. Meanwhile, the combination of real progress in forestalling death and the matching medical and media hype about past and coming victories over mortality mean that death itself is coming to be seen as a biological accident, a contingent event, not a fixed given. People die now because of bad luck, indifference to good living habits, unfortunate genetics, and the like, or because they have the misfortune of dying before a cure for their fatal disease is at hand. Mourning likewise is changing. The old custom of the deceased being laid out in their living rooms, followed by a funeral, has long given way to a movement away from public funerals to private ones followed later by a memorial ceremony. No more dead bodies on display to grieve over, but soothing ceremonies of remembrance.

    Suicidal deaths involving explosives unconnected to terrorism are rare. The investigation of deaths from explosive devices requires a multidisciplinary collaborative effort, as demonstrated in this study. Reported are 2 cases of nonterrorist suicidal explosive-related deaths with massive craniocerebral destruction. The first case involves a 20-year-old man who was discovered in the basement apartment of his father's home seconds after an explosion. At the scene investigators recovered illegal improvised power-technique explosive devices, specifically M-100s, together with the victim's handwritten suicide note. The victim exhibited extensive craniofacial injuries, which medicolegal officials attributed to the decedent's intentionally placing one of these devices in his mouth. The second case involves a 46-year-old man who was found by his wife at his home. In the victim's facial wound, investigators recovered portions of a detonator blasting cap attached to electrical lead wires extending to his right hand. A suicide note was discovered at the scene. The appropriate collection of physical evidence at the scene of the explosion and a detailed examination of the victim's history is as important as documentation of injury patterns and recovery of trace evidence at autopsy. A basic understanding of the variety of explosive devices is also necessary. This investigatory approach greatly enhances the medicolegal death investigator's ability to reconstruct the fatal event as a means of separating accidental and homicidal explosive-related deaths from this uncommon form of suicide.

    A review of 4756 deaths investigated by the Occupational Safety and Health Administration (OSHA) in 1984-6 found 233 deaths from asphyxiation and poisoning, excluding asphyxiations from trench cave-ins. The highest rates were in the oil and gas industry and in utilities. Toxic gases were the largest group (65) followed by simple asphyxiants (48), mechanical causes (42), and solvents (35). Deaths from solvents were significantly more likely in young workers. Nine deaths were caused by improper air supply to respirators and five by recreational inhalation of gas or vapours. Of the 146 deaths in confined spaces, only 12% were in rescuers, fewer than previously reported. PMID:2775673

    In 2008, the number of poisoning deaths exceeded the number of motor vehicle traffic deaths and was the leading cause of injury death for the fi rst time since at least 1980. During the past three decades, the poisoning death rate nearly tripled, while the motor vehicle traffic death rate decreased by one-half. During this period, the percentage of poisoning deaths that were caused by drugs increased from about 60% to about 90%. The population groups with the highest drug poisoning death rates in 2008 were males, people aged 45–54 years, and non-Hispanic white and American Indian or Alaska Native persons. The vast majority of drug poisoning deaths are unintentional (see Appendix table). Opioid analgesics were involved in more drug poisoning deaths than other specified drugs, including heroin and cocaine. Opioid analgesics were involved in nearly 15,000 deaths in 2008, while cocaine was involved in about 5,100 deaths and heroin was involved in about 3,000 deaths (data not shown). Deaths involving opioid analgesics may involve other drugs as well, including benzodiazepines (2). In addition to an increase in the number of deaths caused by drug poisoning, increases in drug use, abuse, misuse, and nonfatal health outcomes have been observed. In the past two decades, there has been an increase in the distribution and medical use of prescription drugs, including opioid analgesics (3). From 1999 to 2008, the use of prescription medications increased (4). In 2007–2008, 48% of Americans used at least one prescription drug in the past month and 11% of Americans used five or more prescriptions in the past month. Analgesics for pain relief were among the common drugs taken by adults aged 20–59 years (4). In 2009–2010, over 5 million Americans reported using prescription pain relievers nonmedically in the past month (that is, without a doctor’s prescription or only for the experience or feeling they caused), and the majority of people using prescription pain relievers

The victims were predominantly young males (mean age 25 years). Slightly more than half of the deaths were caused by another person and were inflicted at close range. The main cause of the incidents was human error. The majority of the involved firearms were legal; however, most victims killed with illegal firearms were under the influence of alcohol and/or drugs at the time. The death rate decreased significantly following the introduction of the hunter's examination in 1985. Education and training associated with the hunter's examination was at least partially responsible for the decline in fatalities after 1985. Future prevention should target the availability of illegal firearms. PMID:27364274

    1987-01-01

    Recently published evidence indicates that involuntary smoking causes an increased risk of lung cancer among nonsmokers. Information was compiled on the proportion of people who had never smoked among victims of lung cancer, the risk of lung cancer for nonsmokers married to smokers and the prevalence of such exposure. On the basis of these data we estimate that 50 to 60 of the deaths from lung cancer in Canada in 1985 among people who had never smoked were caused by spousal smoking; about 90% occurred in women. The total number of deaths from lung cancer attributable to exposure to tobacco smoke from spouses and other sources (mainly the workplace) was derived by applying estimated age- and sex-specific rates of death from lung cancer attributable to such exposure to the population of Canadians who have never smoked; about 330 deaths from lung cancer annually are attributable to such exposure.

    The causes of death in 466 X chromatin positive males (Klinefelter's syndrome) studied prospectively over the last 25 years have been analysed. We have previously reported the overall mortality to be increased by 50% and life expectancy reduced by about five years. A highly significant increase in mortality from cerebrovascular disease was observed in the sub group considered to be most representative of X chromatin positive males in general. In the age group up to 45 years this increase could be attributed to deaths from subarachnoid haemorrhage. An increase in mortality from respiratory diseases was observed in those ascertained in psychiatric hospitals. In the sample as a whole there were small but highly significant numbers of deaths from carcinoma of the breast and aortic valve disease. The deaths from carcinoma of the breast were comparable with those expected if female mortality rates were applied. PMID:4086964

Opioid analgesics were involved in nearly 15,000 deaths in 2008, while cocaine was involved in about 5,100 deaths and heroin was involved in about 3,000 deaths (data not shown). Deaths involving opioid analgesics may involve other drugs as well, including benzodiazepines (2). In addition to an increase in the number of deaths caused by drug poisoning, increases in drug use, abuse, misuse, and nonfatal health outcomes have been observed. In the past two decades, there has been an increase in the distribution and medical use of prescription drugs, including opioid analgesics (3). From 1999 to 2008, the use of prescription medications increased (4). In 2007–2008, 48% of Americans used at least one prescription drug in the past month and 11% of Americans used five or more prescriptions in the past month. Analgesics for pain relief were among the common drugs taken by adults aged 20–59 years (4). In 2009–2010, over 5 million Americans reported using prescription pain relievers nonmedically in the past month (that is, without a doctor’s prescription or only for the experience or feeling they caused), and the majority of people using prescription pain relievers

    For millennia, human beings have wondered what happens after death. What is the first-person experience of dying and being brought back to life? Technological advances in resuscitation science have now added an intriguing new chapter to the literature of out-of-body or near-death experiences by eliciting detailed and vivid accounts of those who have approached the threshold of death. Steve Paulson, executive producer and host of To the Best of Our Knowledge, moderated a discussion that included neurologist Kevin Nelson, neuropsychiatrist Peter Fenwick, emergency medicine expert Sam Parnia, and orthopedic surgeon and drowning survivor Mary Neal; they share some remarkable stories and discuss how they analyze such experiences in light of their own backgrounds and training. The following is an edited transcript of the discussion from December 11, 2013, 7:00-8:30 PM, at the New York Academy of Sciences in New York City.

  18. Sudden death of effective entanglement

    Sudden death of entanglement is a well-known effect resulting from the finite volume of separable states. We study the case when the observer has a limited measurement capability and analyze the effective entanglement (i.e., entanglement minimized over the output data). We show that in the well-defined system of two quantum dots monitored by single-electron transistors, one may observe a sudden death of effective entanglement when real, physical entanglement is still alive. For certain measurement setups, this occurs even for initial states for which sudden death of physical entanglement is not possible at all. The principles of the analysis may be applied to other analogous scenarios, such as estimation of the parameters arising from quantum process tomography.

    On July 19, 1978, two crewmen aboard a shrimp trawler died and the captain was hospitalized after being exposed to a toxic atmosphere in the ship's hold. Examination of the Coast Guard records of deaths at sea since 1970 led to the identification of 11 incidents involving 32 deaths by asphyxia. All deaths occurred in the unventilated holds of ships in warm waters and during warm months of the year. Asphyxia in the unventilated holds of ships is an underrecognized hazard. We recommend that fishermen be informed of this hazard, that ships' holds be ventilated before they are entered, and that safety protocols be provided to rescuers of persons found unconscious in a ship's hold.

  20. Cell Death in Genome Evolution

    Inappropriate survival of abnormal cells underlies tumorigenesis. Most discoveries about programmed cell death have come from studying model organisms. Revisiting the experimental contexts that inspired these discoveries helps explain confounding biases that inevitably accompany such discoveries. Amending early biases has added a newcomer to the collection of cell death models. Analysis of gene-dependent death in yeast revealed the surprising influence of single gene mutations on subsequent eukaryotic genome evolution. Similar events may influence the selection for mutations during early tumorigenesis. The possibility that an early random mutation might drive the selection for a cancer driver mutation is conceivable but difficult to demonstrate. This was tested in yeast, revealing that mutation of almost any gene appears to specify the selection for a new second mutation. Some human tumors contain pairs of mutant genes homologous to co-occurring mutant genes in yeast. Here we consider how yeast again provide novel insights into tumorigenesis. PMID:25725369

    There are some improvements in management of acute myeloid leukemia (AML). However, induction-induced deaths still remain as a major problem. The aim of this study is to assess clinical parameters affecting early death in patients with AML. 199 AML patients, who were treated with intensive, non-intensive or supportive treatment between 2002 and 2014 in Hacettepe Hematology Department, were analyzed retrospectively. In our study early death rate for elderly was found to be lower than previous reports whereas it was similar for those who were under age of 60. Better ECOG performance (ECOG performance score 0 and 1) and non-intensive treatment associated with lower early death rates, however APL-type disease associated with higher early death rates. ECOG performance score at diagnosis was found to be the most related independent factor with higher rate of early death in 15 days after treatment (P<0.001). Therefore we decided to understand the factors which were related with ECOG. WBC count at diagnosis was found to be the only related parameter with ECOG performance score. Leucocyte count at diagnosis appears like to have an indirect effect on early death in AML patients. It maybe suggested that in recent years there is an improvement in early death rates of elderly AML patients. The currently reported findings require prospective validation and would encourage the incorporation of other next generation genomics for the prediction of early death and overall risk status of AML.

    MVCs are a leading cause of death and disability for teenagers. In Wales, a child death review process has been established to carry out thematic reviews of deaths; this approach is believed to highlight opportunities for prevention that individual case review could not. Cases were 13-year-old to 17-year-old Welsh residents who died as car drivers or passengers between 1 January 2006 and 31 December 2010. An expert panel was convened to review these cases. 28 MVCs occurred and 34 13-17 year olds died; 24 males, 10 females. 51 vehicles were involved; 23 driven by 17-year-old to 19-year-old males. 19 of the 28 MVCs occurred between 21:00 and 05:00. The risk factors identified were consistent with global research on MVC deaths and injuries to teenagers. However, there is a lack of effective interventions to tackle these in the UK. It is recommended that the implementation of Graduated Driver Licensing is considered. PMID:26251467

    Mentally ill people are not to be judged by the same rules as the mentally fit. Prisoners evaluated medically unfit for execution must undergo psychiatric treatment until their mental health is restored. Psychiatrists are placed in an ethical dilemma when asked to judge the mental health of prisoners on death row. A high prevalence of psychiatric and neurological disorders are reported on death row. Health professionals have an important role in implementing codes of ethics prohibiting any involvement in the execution process. Resolutions have already been passed by several associations including the World Medical Association, the American Psychiatric Association and Nordic medical associations.

    1994-03-01

    We instituted two thanatology seminars for medical students and residents which emphasized feelings more than objective data. The seminars began with students filling out a death certificate on themselves. Eighty-four per cent predicted that their own probable cause of death would be from an acute illness. Discussion and reflection on this experience helped them realize how difficult it would be to deal with a chronic illness. By answering a question about what they were most grateful for, they became aware that they valued family and friends most highly. We believe that this experience legitimized feelings which form the basis of empathy.

    1969-11-01

    A sample of death certificates matched with 1960 Census records permitted comparison of response data for items asked on both records. Estimates of bias in death rates which are based on information from the two records are derived from the comparison data. Most of the comparisons yielded small discrepancies of inconsequential effect on the mortality rates. Some large inconsistencies, however, of potentially serious impact on the death rates were observed. The comparisons are examined and the implications of the results for the relevant mortality rates are discussed. In addition, age-specific death rates "corrected" for the disparities found in the age information on the two records are presented.

    2007-01-01

    Background The inaccuracy of death certification can lead to the misallocation of resources in health care programs and research. We evaluated the rate of errors in the completion of death certificates among medical residents from various specialties, before and after an educational intervention which was designed to improve the accuracy in the certification of the cause of death. Methods A 90-min seminar was delivered to seven mixed groups of medical trainees (n = 166) from several health care institutions in Spain. Physicians were asked to read and anonymously complete a same case-scenario of death certification before and after the seminar. We compared the rates of errors and the impact of the educational intervention before and after the seminar. Results A total of 332 death certificates (166 completed before and 166 completed after the intervention) were audited. Death certificates were completed with errors by 71.1% of the physicians before the educational intervention. Following the seminar, the proportion of death certificates with errors decreased to 9% (p < 0.0001). The most common error in the completion of death certificates was the listing of the mechanism of death instead of the cause of death. Before the seminar, 56.8% listed respiratory or cardiac arrest as the immediate cause of death. None of the participants listed any mechanism of death after the educational intervention (p < 0.0001). Conclusion Major errors in the completion of the correct cause of death on death certificates are common among medical residents. A simple educational intervention can dramatically improve the accuracy in the completion of death certificates by physicians. PMID:18005414

  7. Deaths due to Unknown Foodborne Agents

    PubMed Central

    2004-01-01

    This study reviews the available evidence on unknown pathogenic agents transmitted in food and examines the methods that have been used to estimate that such agents cause 3,400 deaths per year in the United States. The estimate of deaths was derived from hospital discharge and death certificate data on deaths attributed to gastroenteritis of unknown cause. Fatal illnesses due to unknown foodborne agents do not always involve gastroenteritis, and gastroenteritis may not be accurately diagnosed or reported on hospital charts or death certificates. The death estimate consequently omitted deaths from unknown foodborne agents that do not cause gastroenteritis and likely overstated the number of deaths from agents that cause gastroenteritis. Although the number of deaths from unknown foodborne agents is uncertain, the possible economic cost of these deaths is so large that increased efforts to identify the causal agents are warranted.

    1992-01-01

    The U.S. Public Health Service Commissioned Corps performs health promotion and disease prevention activities and provides clinical care. The authors examined the epidemiology of deaths among active duty personnel and the hypothesis that, based on the mission, mortality would be less than in the general population, and that deaths would reflect nonpreventable causes. A retrospective record review for the period 1965-89 showed 118 active duty deaths, 26 percent of the number anticipated in a general population group adjusted for age, sex, and race or ethnicity. The five major causes of death were coronary heart disease, suicide, motor vehicle crash, malignant neoplasm, and drowning. Beginning with the mid-1980s, infectious disease became a principal cause of death, the only cause for which the rate trended upward. Among professionals, death rates were highest among sanitarians and veterinarians, and lowest among pharmacists. The only causes for which deaths exceeded the expected number involved suicides and possibly deaths related to acquired immunodeficiency syndrome. Active duty status in the Commissioned Corps was associated with a death rate less than that of comparable groups in the general population. Many of the premature deaths were attributable to preventable causes. PMID:1561297

  9. Regulated Cell Death in AKI

    PubMed Central

    Chen, Guochun; Dong, Guie; Kunzendorf, Ulrich; Krautwald, Stefan

    2014-01-01

    AKI is pathologically characterized by sublethal and lethal damage of renal tubules. Under these conditions, renal tubular cell death may occur by regulated necrosis (RN) or apoptosis. In the last two decades, tubular apoptosis has been shown in preclinical models and some clinical samples from patients with AKI. Mechanistically, apoptotic cell death in AKI may result from well described extrinsic and intrinsic pathways as well as ER stress. Central converging nodes of these pathways are mitochondria, which become fragmented and sensitized to membrane permeabilization in response to cellular stress, resulting in the release of cell death–inducing factors. Whereas apoptosis is known to be regulated, tubular necrosis was thought to occur by accident until recent work unveiled several RN subroutines, most prominently receptor-interacting protein kinase–dependent necroptosis and RN induced by mitochondrial permeability transition. Additionally, other cell death pathways, like pyroptosis and ferroptosis, may also be of pathophysiologic relevance in AKI. Combination therapy targeting multiple cell-death pathways may, therefore, provide maximal therapeutic benefits. PMID:24925726

    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.

    1990-04-01

    The place of death in psychology is reviewed historically. Leading causes for its being slighted as an area of investigation during psychology's early years are presented. Reasons for its rediscovery in the mid-1950s as a legitimate sector for scientific inquiry are then discussed, along with some vicissitudes encountered in carrying out research in the field. This is followed by a description of principal empirical findings, clinical perceptions, and perspectives emerging from work in the thanatological realm. The probability that such urgent social issues as abortion, acquired immunodeficiency syndrome (AIDS), and euthanasia, and such destructive behaviors as drug abuse, alcoholism, and certain acts of violence are associated with attitudes toward death offers a challenge to psychology to enhance the vitality of human response to maladaptive conduct and loss. Recognition of personal mortality is a major entryway to self-knowledge. Although death is manifestly too complex to be the special sphere of any one discipline, psychology's position as an arena in which humanist and physicist-engineer cultures intersect provides us with a meaningful opportunity to advance our comprehension of how death can serve life.

  20. Caspase-independent cell deaths.

    A very common and the best understood of the mechanisms of physiological cell death is apoptosis, resulting from the activation, through either of two primary pathways, of site-specific proteases called caspases. There are, however, many other routes to cell death, prominently including autophagy and proteasomal degradation of critical constituents of cells. These routes are frequently seen in experimental situations in which initiator or effector caspases are inhibited or blocked through genetic means, but they are also encountered during normal physiological and pathological processes. Most frequently, autophagic or proteasomal degradation is used to eliminate massive cytoplasm of very large cells, especially post-mitotic cells, and these pathways are prominent even though caspase genes, messages, and pro-enzymes are found in the cells. These forms of cell death are fully physiological and not simply a default pathway for a defective cell; and they are distinct from necrosis. We do not yet understand the extent to which the pathways are linked, what mechanisms trigger the caspase-independent deaths, and how the choices are made.

  1. The changing geography of major causes of death among middle age white Americans, 1939-1981.

    1987-01-01

    Urban areas, especially the Northeast, are assumed to have the highest death rates from chronic diseases in the United States. Based on analysis of age-adjusted death rates of the white population 35-64 from 1939-1941 through 1979-1981, it is shown that chronic disease rates in the urban Northeast and Midwest have declined compared to the rest of the United States. High rates of chronic as well as traumatic causes of death now characterize the South. Hypotheses are offered to explain these changes, including changes in lifestyle, differences in state government policies, the changing geography of industry and ethnic populations, and the spread of medical care.

    Background Road traffic deaths are a considerable public health problem and a major source of lost financial and human resources. Most mortality occurs in low- and middle-income countries. Objectives This study aimed to measure road traffic fatality rates and years of lost life, and also to depict a view of trends in road traffic deaths from 2004 to 2010 in Yazd city, a province in central Iran. Materials and Methods This retrospective case study analyzed road traffic deaths that were classified under the V01 - V99 codes of the ICD-10 in Yazd province from March 2004 to March 2010, using data that were collected from the death registration system of the Yazd province health center. Cases were classified according to age, sex, time of year, and residence (urban vs. rural). Years of lost life and road fatality rate per 100,000 people were calculated. Data were analyzed using chi-square test and ANOVA with SPSS 16. Results During the seven-year period of this study, 3,028 people in Yazd province died due to road traffic accidents (9.1% of total deaths in the province). Most deaths occurred among people aged 20-24 (15%), men (82.7%), and urban residents (82.6%). Total years of lost life (YLL) were 73,875 (60,337 and 13,489 in men and women, respectively). The road traffic fatality rate per 100,000 was 47.6 in 2004 and 37.6 in 2010. In the study period, the rate of traffic fatalities decreased for men (from 77.9 to 68.5) but this is not the case for women (from 14.8 to 19.2). Road traffic deaths peaked every summer. Conclusions Despite the overall reduction trend, the road traffic fatality rate in Yazd province is still alarmingly high compared to national and global data. In addition, the female population shows increasing death rates. These findings can serve as a basis for health care professionals and policymakers to conduct preventive measures, especially during summer, and plan specifically for reducing fatalities in the female population.

    We describe an approach for quantifying and characterizing the extent to which sudden and unexpected infant deaths (SUIDs) result from unsafe sleep environments (e.g., prone position, bedsharing, soft bedding); and present data on sleep-related infant deaths in NYC. Using a combination of vital statistics and medical examiner data, including autopsy and death scene investigation findings, we analyzed any death due to accidental threat to breathing (ATB) (ICD-10 W75 & W84), and deaths of undetermined intent (UND) (Y10-Y34) between 2000 and 2003 in NYC for the presence of sleep-related factors (SRF). Homicide deaths were excluded as were SIDS, since in NYC SIDS is not a certification option if environmental factors were possibly contributors to the death. All 19 ATB and 69 (75%) UND had SRFs as per the OCME investigation. Black infants and infants born to teen mothers had higher SRF death rates for both ATB and UND deaths. Bedsharing was the most common SRF (53%-ATB; 72%-UND deaths); the majority of non-bedsharing infants were found in the prone position (60%-ATB; 78%-UND deaths). We found a high prevalence of SRFs among ATB and UND deaths. This is the first local study to illustrate the importance of knowing how SUIDs are certified in order to ascertain the prevalence of infant deaths with SRFs. Advancing the research requires clarity on the criteria used by local medical examiners to categorize SUIDs. This will help jurisdictions interpret their infant mortality statistics, which in turn will improve education and prevention efforts. PMID:20177757

    In Brazil, there is a lack of complete records on death certificates, and its reliability is questioned, especially for causes attributed to pregnancy and childbirth. We investigated, based on death certificates of women in reproductive age, any fields for identifying maternal deaths. Documentary research, conducted in hospital records. We analyzed in death certificates, maternal and no maternal deaths, inconclusive deaths and hidden deaths. To analyze the underlying causes of death we used ICD 10th Revision. Of the 301 death certificates reviewed, 60% had the fields 43/44 completed, and 40% had these fields blank and/or ignored. We found 58.5% of no maternal deaths, 2% of maternal deaths and 39.5% inconclusive. The analysis of inconclusive deaths allowed us to classify 4.3% as hidden deaths. To overcome the incompletitudes of civil registries, it is necessary that all health professionals be committed to the reliability of the information, so the priority target could be reached.

  5. The generalized time variable reconstructed birth-death process.

    2012-05-01

    Much recent research has investigated the effect that different time variable birth-death processes have on the distribution of branching times in phylogenies of extant taxa. Previous work has shown how to calculate the distributions of number of lineages and branching times for a reconstructed constant rate birth-death process that started with one or two reconstructed lineages at some time in the past or ended with some number of lineages in the present. Here I expand that work to include any time variable birth-death process that starts with any number of reconstructed lineages and/or ends with any number of reconstructed lineages at any time, and I calculate a number of distributions under that process. I also explore the discrete time birth-death process which operates as an efficient and accurate numerical solution to any time-variable birth-death process and allows for the analytical incorporation of sampling and mass extinctions. I describe how these distributions can be used to compare different time variable models using maximum likelihood analysis, and I show how to simulate random trees under any of these models. I also introduce two visual methods for evaluating different time variable birth-death processes; these methods illustrate the shape of distributions for the number of lineages and waiting times by plotting them over time.

    Abstract A retrospective study was conducted at Tongji Forensic Medical Center in Hubei (TFMCH) from 1999 to 2014. Forty-nine cases of sudden unexplained nocturnal death syndrome (SUNDS) were collected. The SUNDS rate was 1.0% in the total number of cases, in which an incidence was fluctuating over the years. Interestingly, April and January, and 3:00 to 6:00 am were the peak months and times of death. Among the decedents, farmers and migrant workers accounted for 67.3%. The syndrome predominantly attacked males in their 30s. One victim had sinus tachycardia. Thirteen victims (26.5%) were witnessed and had abnormal symptoms near death. Macroscopically, compared to sudden noncardiac deaths, the weights of brain, heart, and lungs had no statistical difference in SUNDS. Microscopically, the incidence of lung edema (45 cases, 91.8%) was significantly higher in SUNDS group than in the control group (27 cases, 55.1%). 82.9% of 35 SUNDS cases examined displayed minor histological anomalies of the cardiac conduction system (CCS), including mild or moderate fatty, fibrous or fibrofatty tissue replacement, insignificant stenosis of node artery, and punctate hemorrhage in the node area. These findings suggested that minor CCS abnormalities might be the substrates for some SUNDS deaths. Therefore, SUNDS victims might suffer ventricular fibrillation and acute cardiopulmonary failure before death. Further in-depth studies are needed to unveil the underlying mechanisms of SUNDS.

    OBJECTIVES: To investigate the demographic characteristics and circumstances surrounding fatal snowmobile accidents in Ontario, to examine the risk factors and to observe any fatality trends over the study period. DESIGN: Case series. PATIENTS: All 131 people who died accidentally while operating a snowmobile in Ontario from 1985-86 to 1989-90. Records were obtained from the chief coroner's office; registration data were obtained from the Ministry of Transportation. RESULTS: Although the absolute number of deaths increased each year, owing to a rapid increase in the number of registered snowmobiles, the risk of death from snowmobile accidents remained relatively constant. Deaths occurred most frequently in northeastern Ontario. Youths and men predominated among the victims. Fatal accidents occurred more often on lakes (in 66% of the cases in which this information was known) than on roads (in 26%) or trails (in 8%). Weekend fatalities predominated, and deaths occurred most often during times of suboptimal lighting (from 4 pm to 8 am). The driver was killed in 84% of the cases in which the person's role was known. Alcohol use before death was implicated in 69% of the cases, the level exceeding the Ontario legal limit in 59%. CONCLUSION: Snowmobile-related deaths result from factors that are generally avoidable. Strategies need to be instituted to reduce the rate of these events. PMID:1735039

    Does a combination of lifestyle pressures and personality, as reflected in genre, lead to the early death of popular musicians? We explored overall mortality, cause of death, and changes in patterns of death over time and by music genre membership in popular musicians who died between 1950 and 2014. The death records of 13,195 popular musicians were coded for age and year of death, cause of death, gender, and music genre. Musician death statistics were compared with age-matched deaths in the US population using actuarial methods. Although the common perception is of a glamorous, free-wheeling lifestyle for this occupational group, the figures tell a very different story. Results showed that popular musicians have shortened life expectancy compared with comparable general populations. Results showed excess mortality from violent deaths (suicide, homicide, accidental death, including vehicular deaths and drug overdoses) and liver disease for each age group studied compared with population mortality patterns. These excess deaths were highest for the under-25-year age group and reduced chronologically thereafter. Overall mortality rates were twice as high compared with the population when averaged over the whole age range. Mortality impacts differed by music genre. In particular, excess suicides and liver-related disease were observed in country, metal, and rock musicians; excess homicides were observed in 6 of the 14 genres, in particular hip hop and rap musicians. For accidental death, actual deaths significantly exceeded expected deaths for country, folk, jazz, metal, pop, punk, and rock.

    Using multiple-cause-of-death data, this study examines diabetes mellitus as a cause of mortality. During the 2004-to-2008 period, diabetes mellitus was listed as either the underlying cause or a contributing cause of 119,617 deaths. It was more than twice as likely to be a contributing than the underlying cause of death. When it was identified as the underlying cause of death, diabetes mellitus was rarely the only cause. The diabetes mellitus mortality rate was relatively high among males, older individuals, and people living in lower-income neighbourhoods. Provincial/Territorial differences in rates of death from diabetes mellitus were considerable. When diabetes mellitus was the underlying cause of death, cardiovascular diseases were listed as a contributing cause most often, and when diabetes mellitus was a contributing cause, cardiovascular diseases were most likely to be the underlying cause.

    To identify accurate predictors for the risk of sudden death in patients with familial dysautonomia (FD). Ten-minute resting high-fidelity 12-lead ECGs were obtained from 14 FD patients and 14 age/gender-matched healthy subjects. Multiple conventional and advanced ECG parameters were studied for their ability to predict sudden death in FD over a subsequent 4.5-year period, including multiple indices of linear and non-linear heart rate variability (HRV); QT variability; waveform complexity; high frequency QRS; and derived Frank-lead parameters. Four of the 14 FD patients died suddenly during the follow-up period, usually with concomitant pulmonary disorder. The presence of low vagally-mediated HRV was the ECG finding most predictive of sudden death. Concomitant left ventricular hypertrophy and other ECG abnormalities such as increased QTc and JTc intervals, spatial QRS-T angles, T-wave complexity, and QT variability were also present in FD patients, suggesting that structural heart disease is fairly common in FD. Although excessive or unopposed cardiac vagal (relative to sympathetic) activity has been postulated as a contributor to sudden death in FD, the presence of low vagally-mediated HRV was paradoxically the best predictor of sudden death. However, we suggest that low vagally-mediated HRV be construed not as a direct cause of sudden death in FD, but rather as an effect of concurrent pathological processes, especially hypoxia due to pulmonary disorders and sleep apnea, that themselves increase the risk of sudden death in FD and simultaneously diminish HRV. We speculate that adenosine may play a role in sudden death in FD, possibly independently of vagal activity, and that adenosine inhibitors such as theophylline might therefore be useful as prophylaxis in this disorder.

    Objective The objective of this study is to evaluate the rate of and etiology for preventable deaths in patients with traumatic brain injuries (TBIs). Methods We conducted a retrospective, multicenter review of patients with TBIs who died within 7 days of their traumatic event from June 2008 to May 2009. Three board certified emergency physicians independently reviewed every case using a structured survey format. Cases were considered preventable deaths only if all physicians independently agreed the death was preventable. Management errors contributing to the preventable death were determined. Results Forty-one patients who died from TBI were eligible. Preventable deaths were identified in nine (22%; 95% confidence interval [CI], 11 to 28) cases. Fifty-six management errors were identified including 36 (64%; 95% CI, 50 to 77) in the emergency department and 13 (23%; 95% CI, 13 to 36) in the prehospital phase. Thirty (54%; 95% CI, 40 to 67) management errors were process-related, and 26 (46%; 95% CI, 33 to 60) were structure-related. Conclusion An important and measurable rate of preventable mortality occurs in the initial care of TBI patients. Errors were common and most occurred in the emergency department. In addition, errors were common in the prehospital phase but did not always lead to mortality. When analyzed by type of problem, both process-related and structure-related errors occurred in similar proportions.

    AIMS—To study the epidemiological, clinical, and pathological characteristics of sudden unexpected non-violent deaths between 1and 19years.
METHODS—Population based observational study of all sudden unexpected non-violent deaths between 1 and 19 years, from 1990 to 1997,in a north Spain county (Bizkaia). In each case, clinical information and circumstances of death were obtained and a complete forensic autopsy was performed.
RESULTS—There were 34 sudden unexpected non-violent deaths. The mortality rate was 1.7 per 100 000 persons per year (representing 9% of the mortality rate of all non-violent deaths). In 10 cases the cause of death was cardiac, in 13 cases extracardiac, and 11 cases were unexplained. In 17 cases there were no pathological antecedents and in nine cases death occurred in patients with known disorders. Syncopes prior to death were present in five cases. Exercise related deaths occurred in seven cases (mainly associated with cardiac causes). Eight cases were "death in bed".

    Background A retrospective analysis of deaths registered in the Brazilian Mortality System was conducted to quantify the under-reporting of HIV/AIDS deaths and those misclassified to AIDS-related conditions in the 15–49 years old population in Brazil. Methods Death rates for AIDS-related diseases were calculated by age and sex for 1985–2009. Changes in the age-sex-specific death rates over time were used to identify conditions likely to be misclassified AIDS deaths and to quantify the corresponding number of misclassified deaths. Deaths due to ill-defined causes were redistributed across all other natural causes of death. The resulting total number of AIDS deaths was further adjusted for incompleteness of the mortality reporting system. Results Out of the 28 potential causes of death investigated, five increased in the same distinct age pattern as AIDS: pneumonia, Kaposi's sarcoma, other immunodeficiencies, other septicaemia and toxoplasmosis. 18 490 deaths due to these five causes were recoded to HIV/AIDS from 1985 to 2009. 38 145 deaths due to ill-defined causes were redistributed to AIDS and 15 485 were added to the number of AIDS deaths to correct for completeness of the mortality system in Brazil. Altogether, 72 120 deaths were recoded to AIDS between 1985 and 2009 and added to the reported 194 445 AIDS related deaths in the country, representing 27% misclassification of AIDS deaths in Brazil. Conclusions This study demonstrated that AIDS mortality is underestimated by the official mortality information system in Brazil. Efforts need to be made to reduce misclassification of causes of death in the future and identify ways in which the confidentiality of information regarding cause of death can be maintained.

    In the triennium 2006-2008, 261 women in the UK died directly or indirectly related to pregnancy. The overall maternal mortality rate was 11.39 per 100,000 maternities. Direct deaths decreased from 6.24 per 100,000 maternities in 2003-2005 to 4.67 per 100,000 maternities in 2006–2008 (p = 0.02). This decline is predominantly due to the reduction in deaths from thromboembolism and, to a lesser extent, haemorrhage. For the first time there has been a reduction in the inequalities gap, with a significant decrease in maternal mortality rates among those living in the most deprived areas and those in the lowest socio-economic group. Despite a decline in the overall UK maternal mortality rate, there has been an increase in deaths related to genital tract sepsis, particularly from community acquired Group A streptococcal disease. The mortality rate related to sepsis increased from 0.85 deaths per 100,000 maternities in 2003-2005 to 1.13 deaths in 2006-2008, and sepsis is now the most common cause of Direct maternal death. Cardiac disease is the most common cause of Indirect death; the Indirect maternal mortality rate has not changed significantly since 2003-2005. This Confidential Enquiry identified substandard care in 70% of Direct deaths and 55% of Indirect deaths. Many of the identified avoidable factors remain the same as those identified in previous Enquiries. Recommendations for improving care have been developed and are highlighted in this report. Implementing the Top ten recommendations should be prioritised in order to ensure the overall UK maternal mortality rate continues to decline.

    Obstructive and central sleep apnea have been associated with increased risk of adverse cardiovascular events and mortality. Sympathetic dysregulation occurring as a result of the respiratory disturbance is thought to play a role in this increased risk. Sleep apnea increases the risk of arrhythmias, myocardial ischemia/infarction, stroke, and heart failure, all of which may increase mortality risk. A higher incidence of nocturnal arrhythmias, cardiac ischemia, and sudden death has been noted in subjects with sleep-disordered breathing (SDB). In this review, the association between SDB and each of these conditions is discussed, as well as the potential mechanisms underlying these risks and the effects of treatment of SDB. Particular emphasis is placed on the relationship between SDB and nocturnal atrial and ventricular arrhythmias, myocardial ischemia/infarction and sudden death. PMID:26188022

    2011-01-01

    Thermotherapy consisting of heating tumors to death appears to be a suitable method to achieve tumor ablation in a noninvasive manner with minimal side effects but developments were hampered because of the lack of specificity of the heating method. New interests have emerged by introducing nanoparticles as energy absorbent agents in tumor tissue to locally enhance the action of irradiation, hence increasing the specificity of the method. Mechanisms of tumor death depend on the nature of the nanoparticles and irradiation modalities. They can be induced either by heat-dependent or by heat-independent phenomena. As discussed in this article, it can reasonably be expected that the recent methods of thermotherapy developed with nanoparticles have a tremendous potential for cancer treatments. However, overcoming challenging milestones is now required before the method will be ready for the treatment of a wide range of cancers.

    Abstract Objective To identify the predictors of residential fire deaths in the Ontario pediatric population using systematically collected data from the Office of the Chief Coroner. Design Retrospective cohort study. Setting Ontario. Participants Children younger than 16 years of age who died in accidental residential fires in Ontario between January 1, 2001, and December 31, 2006. Main outcome measures The study retrospectively reviewed the coroner’s case files for 60 subjects who qualified according to the selection criteria. Reviewed documents included the coroner’s investigation statements, autopsy reports, toxicology reports, fire marshal’s reports, police reports, and Children’s Aid Society (CAS) reports. Information on a range of demographic, behavioural, social, and environmental factors was collected. Statistical tests, including relative risk, relative risk confidence intervals, and χ2 tests were performed to determine the correlation between factors of interest and to establish their significance. Results Thirty-nine fire events resulting in 60 deaths occurred between 2001 and 2006. Fire play and electrical failures were the top 2 causes of residential fires. More fires occurred during the night (midnight to 9 am) than during the day (9 am to midnight). Nighttime fires were most commonly due to electrical failures or unattended candles, whereas daytime fires were primarily caused by unsupervised fire play and stove fires. Smoke alarms were present at 32 of 39 fire events (82%), but overall alarm functionality was only 54%. Children from families with a history of CAS involvement were approximately 32 times more likely to die in fires. Conclusion Risk factors for pediatric fire death in Ontario include smoke alarm functionality, fire play, fire escape behaviour, and CAS involvement. Efforts to prevent residential fire deaths should target these populations and risk factors, and primary care physicians should consider education around these

    Objective Understanding the causes of death is key to tackling the burden of three million annual neonatal deaths. Resource-poor settings lack effective vital registration systems for births, deaths and causes of death. We set out to describe cause-specific neonatal mortality in rural areas of Malawi, Bangladesh, Nepal and rural and urban India using verbal autopsy (VA) data. Design We prospectively recorded births, neonatal deaths and stillbirths in seven population surveillance sites. VAs were carried out to ascertain cause of death. We applied descriptive epidemiological techniques and the InterVA method to characterise the burden, timing and causes of neonatal mortality at each site. Results Analysis included 3772 neonatal deaths and 3256 stillbirths. Between 63% and 82% of neonatal deaths occurred in the first week of life, and males were more likely to die than females. Prematurity, birth asphyxia and infections accounted for most neonatal deaths, but important subnational and regional differences were observed. More than one-third of deaths in urban India were attributed to asphyxia, making it the leading cause of death in this setting. Conclusions Population-based VA methods can fill information gaps on the burden and causes of neonatal mortality in resource-poor and data-poor settings. Local data should be used to inform and monitor the implementation of interventions to improve newborn health. High rates of home births demand a particular focus on community interventions to improve hygienic delivery and essential newborn care. PMID:25972443

    Donation after brain death followed by circulatory death (DBCD) is a unique practice in China. The aim of this study was to define the pathologic characteristics of DBCD liver allografts in a porcine model. Fifteen male pigs (25-30 kg) were allocated randomly into donation after brain death (DBD), donation after circulatory death (DCD) and DBCD groups. Brain death was induced by augmenting intracranial pressure. Circulatory death was induced by withdrawal of life support in DBCD group and by venous injection of 40 mL 10% potassium chloride in DCD group. The donor livers were perfused in situ and kept in cold storage for 4 h. Liver tissue and common bile duct samples were collected for hematoxylin and eosin staining, TUNEL testing and electron microscopic examination. Spot necrosis was found in hepatic parenchyma of DBD and DBCD groups, while a large area of necrosis was shown in DCD group. The apoptosis rate of hepatocytes in DBD [(0.56±0.30)%] and DBCD [(0.50 ± 0.11)%] groups was much lower than that in DCD group [(3.78±0.33)%] (P<0.05). And there was no significant difference between DBD group and DBCD group (P>0.05)). The structures of bile duct were intact in both DBD and DBCD groups, while the biliary epithelium was totally damaged in DCD group. Under electron microscope, the DBD hepatocytes were characterized by intact cell membrane, well-organized endoplasmic reticulum, mild mitochondria edema and abundant glycogens. Broken cell membrane, mild inflammatory cell infiltration and sinusoidal epithelium edema, as well as reduced glycogen volume, were found in the DBCD hepatocytes. The DCD hepatocytes had more profound cell organelle injury and much less glycogen storage. In conclusion, the preservation injury of DBCD liver allografts is much less severe than that of un-controlled DCD, but more severe than that of DBD liver allografts under electron microscope, which might reflect post-transplant liver function to some extent.

    We analysed time trends in the pulmonary embolism (PE) mortality rates in Germany from 2004 and assessed for an association between the use of anticoagulants and PE caused mortality. We extracted age-specific number of deaths due to PE (ICD-10 I26) from 2004 to 2011 as available from the WHO mortality databases. In addition we derived defined daily dosage (DDD) of prescribed anticoagulants and the low molecular heparin Enoxaparin for the years 2004-2011 from the statutory health insurance-drug-information system reports. Age-standardized PE mortality per 100,000 decreased from 5.9283 in year 2004 to 4.4876 in 2011 (-24.3 %). Amounts of prescribed anticoagulants increased in this period from 271,810.7 × 1000 DDD to 416,611.8 × 1000 DDD (+53.3 %), that of Enoxaparin increased from 27,071.1 × 1000 DDD in 2004 97,276.5 × 1000 DDD in 2011. The PE mortality is negatively correlated with anticoagulants (-0.9463, p = 0.0004) as well as with enoxaparin (-0.9740, p < 0.0001) and of DDD of Enoxaparin per 1000 insured (-0.9682, p < 0.0001). In univariate linear regression model, anticoagulants, Enoxaparin and Enoxaparin per 1000 insured all reach significance (p = 0.0004, p = 4.31 × 10(-5) and p = 0.0001 respectively). Multiple regression models show that Enoxaparin has the most robust effect. Including the time trend in the model does not alter the results. Our study shows that increasing number of prescribed Enoxaparin in an outpatient setting might be one determinant of decreasing PE mortality rate in Germany since 2004.

    Context Many state and local areas are affected by the national epidemic of drug-related mortality, which recently has shown signs of a rising licit-to-illicit drug death ratio. Appropriate local public health surveillance can help to monitor and control this epidemic. Objective Using our state as an example, we sought to illustrate how to describe the changes in drug death rates, causes, and circumstances. In contrast to most other surveillance reports, our approach includes both drug-induced and drug-related deaths and both demographic and socioeconomic decedent characteristics. Design Cross-sectional study. Setting All residents of the State of Wisconsin. Participants Decedents from 1999–2008. Main outcome measure Annual numbers and population-based rates of deaths due to drugs, including both identified and unidentified drugs. Information was obtained from death certificates with any of approximately 270 underlying, immediate, or contributing cause of death codes from the International Classification of Diseases 10th Revision. Results Drug-related death rates increased during much of the 10-year study period, and the ratio of male to female deaths rose. The median age at death from drug-related causes was 43 years. Opioid analgesic poisoning surpassed cocaine and heroin poisoning as the most frequent type of fatal drug poisoning. Of all 4828 deaths from drug-related causes--virtually all of which were certified by a county medical examiner or coroner--3,410 (71%) were unintentional, and 1,053 (22%) were suicide. The unintentional-to-suicide death rate ratio grew from 1.6 to 3.5 during the study period. Methadone-related deaths increased from 10 in 1999 to 118 in 2008 (1080%), while benzodiazepine-related deaths rose from 23 to 106 (361%). Conclusions Although premature deaths from drug use and abuse continue to rise, in some states even surpassing motor vehicle crash deaths, multiple cause of death information from death certificates is available to monitor

    The aims of this study were to describe causes of death during the 10-year period between 1995 and 2004 in a large urban jail in Chicago; to compare disease specific mortality rates between the jail population and the general population; to explore demographic and incarceration characteristics of the inmates who died in the jail by cause of death; and to examine gender difference in demographic characteristics, incarceration patterns, and causes of death. A total of 178 deaths occurring in the jail over a 10-year period (1995-2004) were reviewed. Age-adjusted disease-specific mortality rates were computed for the jail population and compared with the rates in the US general population. Cause of death, demographic variables, and incarceration related factors were retrieved from multiple computerized databases. Descriptive analyses were performed to examine demographic and incarceration-related patterns by cause of death and gender. Heart disease was the most frequent cause of death in the jail population, followed by cerebrovascular disease and suicide. Mortality rates for heart diseases, infectious/inflammatory conditions and suicide were higher for jail inmates than the general population. Black inmates accounted for the majority of deaths due to illnesses and homicide, and a much higher proportion of white and Hispanic inmates were involved in suicide deaths. Deaths due to drug overdose or withdrawal were disproportionately higher among female inmates compared with male inmates. Consistent review of mortality rates and causes of deaths in jail can be a useful tool to better understand health issues and needs of jail inmates. Surveillance of acute and chronic illnesses and strategic reengineering of jail health care is a key to quality improvement for incarcerated populations for whom the jail system becomes their primary care provider.

  9. The death system according to Robert Kastenbaum.

    PubMed

    Corr, Charles A

    This article focuses on Robert Kastenbaum's seminal concept of the societal death system. Beginning with conflicting claims that America is a death-denying society versus a death-accepting society, the article reports Kastenbaum's definition and description of the death system in American society and sets forth the seven functions and five elements or components of that death system. Next, the article notes Kastenbaum's further claim that "All cultures, past and present, have had death systems." Finally, two basic lessons are drawn from the foregoing: (1) Kastenbaum's concept of the death system provides a robust framework to explain the networks societies interpose between their members and death, focusing in particular on a more or less integrated and dynamic network within American society whose functions and components are not difficult to recognize in the ways in which they organize many aspects of the lives of individuals who live within that society; and (2) It is preposterous to assert without qualification that America is a death-denying society when there are so many activities and components within that society that are in whole or in part related to death, i.e., although it may be true that many aspects of the contemporary American death system appear to seek to remove death from the mainstream of life, there is ample evidence to indicate that American society as a whole and individuals within that society both accept and deny death simultaneously.

    The rate of sudden infant death decreased after the publication of the first guidelines regarding infant sleep position and safe environment in 1992. From 2005 onwards, infant deaths by suffocation, choking or entrapment have increased. Some of them were associated with wedges, positioning devices, and bumper pads. Media and manufacturers should follow safe sleep guidelines in their messaging and advertising, but there is a lack of control over this. We emphasize the important role of health professionals in disseminating the recommendation for a safe infant sleep environment. PMID:23381706

    In this short report, we describe and compare mortality data for injuries in children aged <15 years in the WHO European region as estimated by the WHO Global Health Estimates for 2000 and 2011. Child injury deaths have decreased overall. Mortality rate ratios between low- and middle-income countries (LMIC) and high-income countries in the region show an increase in relative inequalities for childhood deaths from unintentional injuries and a narrowing from intentional injury. This growing inequality in unintentional injury is a public health concern and calls for renewed efforts to reduce childhood injuries in LMIC the region. PMID:26045525

    The objective of the study was to compare various predictors of death obsession (i.e., anxiety, optimism, pessimism), and self-ratings of religiosity, physical health, mental health, happiness, and satisfaction with life, among 2 samples of college students recruited from two different cultures: Kuwait (n = 271) and United Kingdom (n = 205). The findings suggest that anxiety, among both samples, pessimism among the Kuwait sample, and (un) happiness among the U.K. sample, might provide a good theoretical and empirical context with which to better understand the causes and consequences of death obsession.

    According to the 2006 Census, almost the Canadian population were foreign-born, a percentage that is projected to reach at least 25% by 2031. Studies based on age-standardized mortality rates (ASMR) have found a healthy immigrant effect, with lower overall rates among immigrants. A duration effect has also been observed-immigrants' mortality advantage lessened as their time in Canada increased. ASMRs based on the 1991 to 2001 census mortality follow-up study indicate a healthy immigrant effect and a duration effect at the national level for all-cause mortality for both sexes. However, at the national level, the mortality rate among women from the United States and from Sub-Saharan Africa was similar to that of Canadian-born women. For the three largest Census Metropolitan Areas (Toronto, Montreal and Vancouver), a healthy immigrant effect was not observed among women or among most men from the United States or Sub-Saharan Africa.

    2013-01-01

    Death due to hypothermia is often accidental and associated with alcohol intoxication, diseases or previous trauma. A very rare phenomenon is suicidal hypothermia. A 74-year-old depressive woman was found dead in a rain barrel with her head above the water level in February at an outdoor temperature of 0 degrees C. Forensic autopsy did not reveal any findings typical of drowning. Likewise, there was no morphological evidence of hypothermia, but this cannot be expected in immersion hypothermia with a very short agony. Unusual situations at scene always require comprehensive police investigations and medicolegal examinations.

  16. The Deaths of Very Massive Stars

    NASA Astrophysics Data System (ADS)

    Woosley, Stan. E.; Heger, Alexander

    The theory underlying the evolution and death of stars heavier than 10 M⊙ on the main sequence is reviewed with an emphasis upon stars much heavier than 30 M⊙. These are stars that, in the absence of substantial mass loss, are expected to either produce black holes when they die, or, for helium cores heavier than about 35 M⊙, encounter the pair instability. A wide variety of outcomes is possible depending upon the initial composition of the star, its rotation rate, and the physics used to model its evolution. These stars can produce some of the brightest supernovae in the universe, but also some of the faintest. They can make gamma-ray bursts or collapse without a whimper. Their nucleosynthesis can range from just CNO to a broad range of elements up to the iron group. Though rare nowadays, they probably played a disproportionate role in shaping the evolution of the universe following the formation of its first stars.

    2014-01-01

    We seek to change the conversation about brain death by highlighting the distinction between brain death as a biological concept versus brain death as a legal status. The fact that brain death does not cohere with any biologically plausible definition of death has been known for decades. Nevertheless, this fact has not threatened the acceptance of brain death as a legal status that permits individuals to be treated as if they are dead. The similarities between "legally dead" and "legally blind" demonstrate how we may legitimately choose bright-line legal definitions that do not cohere with biological reality. Not only does this distinction bring conceptual coherence to the conversation about brain death, but it has practical implications as well. Once brain death is recognized as a social construction not grounded in biological reality, we create the possibility of changing the social construction in ways that may better serve both organ donors and recipients alike.

    Background. The Argentia region of Newfoundland and Labrador, Canada, was home to a US naval base during a 40-year period between the 1940s and the 1990s. Activities on the base resulted in contamination of the soil and groundwater in the region with chemicals such as heavy metals and dioxins, and residents have expressed concern about higher rates of cancer in their community. This study investigated the rate of cancer diagnosis that is disproportionately high in the Argentia region. Methods. Cases of cancer diagnosed between 1985 and 2011 were obtained for the Argentia region, two comparison communities, and the province of Newfoundland and Labrador. Crude and age-standardized incidence rates of cancer diagnosis were calculated and compared. The crude incidence rate was adjusted for differences in age demographics using census data, and age-standardized incidence rates were compared. Results. Although the Argentia region had a higher crude rate of cancer diagnosis, the age-standardized incidence rate did not differ significantly from the comparison communities or the provincial average. Argentia has an aging population, which may have influenced the perception of increased cancer diagnosis in the community. Conclusions. We did not detect an increased burden of cancer in the Argentia region. PMID:26633979

    The United States is experiencing an epidemic of drug overdose (poisoning) deaths. Since 2000, the rate of deaths from drug overdoses has increased 137%, including a 200% increase in the rate of overdose deaths involving opioids (opioid pain relievers and heroin). CDC analyzed recent multiple cause-of-death mortality data to examine current trends and characteristics of drug overdose deaths, including the types of opioids associated with drug overdose deaths. During 2014, a total of 47,055 drug overdose deaths occurred in the United States, representing a 1-year increase of 6.5%, from 13.8 per 100,000 persons in 2013 to 14.7 per 100,000 persons in 2014. The rate of drug overdose deaths increased significantly for both sexes, persons aged 25-44 years and ≥55 years, non-Hispanic whites and non-Hispanic blacks, and in the Northeastern, Midwestern, and Southern regions of the United States. Rates of opioid overdose deaths also increased significantly, from 7.9 per 100,000 in 2013 to 9.0 per 100,000 in 2014, a 14% increase. Historically, CDC has programmatically characterized all opioid pain reliever deaths (natural and semisynthetic opioids, methadone, and other synthetic opioids) as "prescription" opioid overdoses (1). Between 2013 and 2014, the age-adjusted rate of death involving methadone remained unchanged; however, the age-adjusted rate of death involving natural and semisynthetic opioid pain relievers, heroin, and synthetic opioids, other than methadone (e.g., fentanyl) increased 9%, 26%, and 80%, respectively. The sharp increase in deaths involving synthetic opioids, other than methadone, in 2014 coincided with law enforcement reports of increased availability of illicitly manufactured fentanyl, a synthetic opioid; however, illicitly manufactured fentanyl cannot be distinguished from prescription fentanyl in death certificate data. These findings indicate that the opioid overdose epidemic is worsening. There is a need for continued action to prevent opioid

    Using data from the U.S. Bureau of Justice Statistics and Census Bureau, I estimate death rates of working-age prisoners and nonprisoners by sex and race. Incarceration was more detrimental to females in comparison to their male counterparts in the period covered by this study. White male prisoners had higher death rates than white males who were not in prison. Black male prisoners, however, consistently exhibited lower death rates than black male nonprisoners did. Additionally, the findings indicate that while the relative difference in mortality levels of white and black males was quite high outside of prison, it essentially disappeared in prison. Notably, removing deaths caused by firearms and motor vehicles in the nonprison population accounted for some of the mortality differential between black prisoners and nonprisoners. The death rates of the other groups analyzed suggest that prison is an unhealthy environment; yet, prison appears to be a healthier place than the typical environment of the nonincarcerated black male population. These findings suggest that firearms and motor vehicle accidents do not sufficiently explain the higher death rates of black males, and they indicate that a lack of basic healthcare may be implicated in the death rates of black males not incarcerated.

  10. Heart rate turbulence.

    PubMed

    Cygankiewicz, Iwona

    2013-01-01

    Heart rate turbulence (HRT) is a baroreflex-mediated biphasic reaction of heart rate in response to premature ventricular beats. Heart rate turbulence is quantified by: turbulence onset (TO) reflecting the initial acceleration of heart rate following premature beat and turbulence slope (TS) describing subsequent deceleration of heart rate. Abnormal HRT identifies patients with autonomic dysfunction or impaired baroreflex sensitivity due to variety of disorders, but also may reflect changes in autonomic nervous system induced by different therapeutic modalities such as drugs, revascularization, or cardiac resynchronization therapy. More importantly, impaired HRT has been shown to identify patients at high risk of all-cause mortality and sudden death, particularly in postinfarction and congestive heart failure patients. It should be emphasized that abnormal HRT has a well-established role in stratification of postinfarction and heart failure patients with relatively preserved left ventricular ejection fraction. The ongoing clinical trials will document whether HRT can be used to guide implantation of cardioverter-defibrillators in this subset of patients, not covered yet by ICD guidelines. This review focuses on the current state-of-the-art knowledge regarding clinical significance of HRT in detection of autonomic dysfunction and regarding the prognostic significance of this parameter in predicting all-cause mortality and sudden death.

Abnormal HRT identifies patients with autonomic dysfunction or impaired baroreflex sensitivity due to variety of disorders, but also may reflect changes in autonomic nervous system induced by different therapeutic modalities such as drugs, revascularization, or cardiac resynchronization therapy. More importantly, impaired HRT has been shown to identify patients at high risk of all-cause mortality and sudden death, particularly in postinfarction and congestive heart failure patients. It should be emphasized that abnormal HRT has a well-established role in stratification of postinfarction and heart failure patients with relatively preserved left ventricular ejection fraction. The ongoing clinical trials will document whether HRT can be used to guide implantation of cardioverter-defibrillators in this subset of patients, not covered yet by ICD guidelines. This review focuses on the current state-of-the-art knowledge regarding clinical significance of HRT in detection of autonomic dysfunction and regarding the prognostic significance of this parameter in predicting all-cause mortality and sudden death.

    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

    Neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease trigger neuronal cell death through endogenous suicide pathways. Surprisingly, although the cell death itself may occur relatively late in the course of the degenerative process, the mediators of the underlying cell-death pathways have shown promise as potential therapeutic targets.
