Few studies have examined trends in pancreatic cancer death rates in the United States, and there have been no studies examining recent trends using age-period-cohort analysis. Annual percentage change in pancreatic cancer death rates was calculated for 1970 to 2009 by sex and race among adults aged 35 to 84 years using US mortality data provided by the National Center for Health Statistics and Joinpoint Regression. Age-period-cohort modeling was performed to evaluate the changes in cohort and period effects. All statistical tests were two-sided. In white men, pancreatic cancer death rates decreased by 0.7% per year from 1970 to 1995 and then increased by 0.4% per year through 2009. Among white women, rates increased slightly from 1970 to 1984, stabilized until the late 1990s, then increased by 0.5% per year through 2009. In contrast, the rates among blacks increased between 1970 and the late 1980s (women) or early 1990s (men) and then decreased thereafter. Age-period-cohort analysis showed that pancreatic cancer death risk was highest for the 1900 to 1910 birth cohort in men and the 1920 to 1930 birth cohort in women and there was a statistically significant increase in period effects since the late 1990s in both white men and white women (two-sided Wald test, P < .001). In the United States, whites and blacks experienced opposite trends in pancreatic cancer death rates between 1970 and 2009 that are largely unexplainable by known risk factors. This study underscores the needs for urgent action to curb the increasing trends of pancreatic cancer in whites and for better understanding of the etiology of this disease.

To describe the changes in death rates and causes of deaths in Norwegian police cells during the last 2 decades. To review reports on death rates in police cells that have been published in medical journals and elsewhere, and discuss the difficulties of comparing death rates between countries. Data on deaths in Norwegian police cells were collected retrospectively in 2002 and 2012 for two time periods: 1993-2001 (period 1) and 2003-2012 (period 2). Several databases were searched to find reports on deaths in police cells from as many countries as possible. The death rates in Norwegian police cells reduced significantly from 0.83 deaths per year per million inhabitants (DYM) in period 1 to 0.22 DYM in period 2 (p < 0.05). The most common cause of death in period 1 was alcohol intoxication including intracranial bleeding in persons with high blood alcohol levels, and the number declined from 16 persons in period 1 to 1 person in period 2 (p = 0.032). The median death rate in the surveyed Western countries was 0.44 DYM (range: 0.14-1.46 DYM). The number of deaths in Norwegian police cells reduced by about 75% over a period of approximately 10 years. This is probably mainly due to individuals with severe alcohol intoxication no longer being placed in police cells. However, there remain large methodology difficulties in comparing deaths rates between countries. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Early death after a treatment can be seen as a therapeutic failure. Accurate prediction of patients at risk for early mortality is crucial to avoid unnecessary harm and reducing costs. The goal of our work is two-fold: first, to evaluate the performance of a previously published model for early death in our cohorts. Second, to develop a prognostic model for early death prediction following radiotherapy. Patients with NSCLC treated with chemoradiotherapy or radiotherapy alone were included in this study. Four different cohorts from different countries were available for this work (N = 1540). The previous model used age, gender, performance status, tumor stage, income deprivation, no previous treatment given (yes/no) and body mass index to make predictions. A random forest model was developed by learning on the Maastro cohort (N = 698). The new model used performance status, age, gender, T and N stage, total tumor volume (cc), total tumor dose (Gy) and chemotherapy timing (none, sequential, concurrent) to make predictions. Death within 4 months of receiving the first radiotherapy fraction was used as the outcome. Early death rates ranged from 6 to 11% within the four cohorts. The previous model performed with AUC values ranging from 0.54 to 0.64 on the validation cohorts. Our newly developed model had improved AUC values ranging from 0.62 to 0.71 on the validation cohorts. Using advanced machine learning methods and informative variables, prognostic models for early mortality can be developed. Development of accurate prognostic tools for early mortality is important to inform patients about treatment options and optimize care.

Among older adults, deficits in both level and variability of speeded performance are linked to neurological impairment. This study examined whether and when speed (rate), speed (inconsistency), and traditional accuracy-based markers of cognitive performance foreshadow terminal decline and impending death. Victoria Longitudinal Study data spanning 12 years (5 waves) of measurement were assembled for 707 adults aged 59 to 95 years. Whereas 442 survivors completed all waves and relevant measures, 265 decedents participated on at least one occasion and subsequently died. Four main results were observed. First, Cox regressions evaluating the three cognitive predictors of mortality replicated previous results for cognitive accuracy predictors. Second, level (rate) of speeded performance predicted survival independent of demographic indicators, cardiovascular health, and cognitive performance level. Third, inconsistency in speed predicted survival independent of all influences combined. Fourth, follow-up random-effects models revealed increases in inconsistency in speed per year closer to death, with advancing age further moderating the accelerated growth. Hierarchical prediction patterns support the view that inconsistency in speed is an early behavioral marker of neurological dysfunction associated with impending death. PMID:18808249

To examine socioeconomic inequalities in rates of death from injury in children in England and Wales. Analysis of rates of death from injury in children by the eight class version of the National Statistics Socio-Economic Classification (NS-SEC) and by the registrar general's social classification. England and Wales during periods of four years around the 1981, 1991, and 2001 censuses. Children aged 0-15 years. Death rates from injury and poisoning. Rates of death from injury in children fell from 11.1 deaths (95% confidence interval 10.8 to 11.5 deaths) per 100,000 children per year around the 1981 census to 4.0 deaths (3.8 to 4.2 deaths) per 100,000 children per year around the 2001 census. Socioeconomic inequalities remain: the death rate from all external causes for children of parents classified as never having worked or as long term unemployed (NS-SEC 8) was 13.1 (10.3 to 16.5) times that for children in NS-SEC 1(higher managerial/professional occupations). For deaths as pedestrians the rate in NS-SEC 8 was 20.6 (10.6 to 39.9) times higher than in NS-SEC 1; for deaths as cyclists it was 27.5 (6.4 to 118.2) times higher; for deaths due to fires it was 37.7 (11.6 to 121.9) times higher; and for deaths of undetermined intent it was 32.6 (15.8 to 67.2) times higher. Overall rates of death from injury and poisoning in children have fallen in England and Wales over the past 20 years, except for rates in children in families in which no adult is in paid employment. Serious inequalities in injury death rates remain, particularly for pedestrians, cyclists, house fires, and deaths of undetermined intent.

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

The UK has poor lung cancer survival rates and high early mortality, compared to other countries. We aimed to identify factors associated with early death, and features of primary care that might contribute to late diagnosis. All cases of lung cancer diagnosed between 2000 and 2013 were extracted from The Health Improvement Network database. Patients who died within 90 days of diagnosis were compared with those who survived longer. Standardised chest X-ray (CXR) and lung cancer rates were calculated for each practice. Of 20,142 people with lung cancer, those who died early consulted with primary care more frequently prediagnosis. Individual factors associated with early death were male sex (OR 1.17; 95% CI 1.10 to 1.24), current smoking (OR 1.43; 95% CI 1.28 to 1.61), increasing age (OR 1.80; 95% CI 1.62 to 1.99 for age ≥80 years compared to 65-69 years), social deprivation (OR 1.16; 95% CI 1.04 to 1.30 for Townsend quintile 5 vs 1) and rural versus urban residence (OR 1.22; 95% CI 1.06 to 1.41). CXR rates varied widely, and the odds of early death were highest in the practices which requested more CXRs. Lung cancer incidence at practice level did not affect early deaths. Patients who die early from lung cancer are interacting with primary care prediagnosis, suggesting potentially missed opportunities to identify them earlier. A general increase in CXR requests may not improve survival; rather, a more timely and appropriate targeting of this investigation using risk assessment tools needs further assessment.

Infant mortality has decreased nationwide; however, our national rates still log behind those of other industrialized countries, especially the rates for minority groups. This study evaluates the effect of prenatal care and risk factors on infant mortality rates in Chicago. Using linked infant birth and death certificates of Chicago residents for 1989-1995, a total of 5838 deaths occurring during the first year of life were identified. Birth certificate variables, especially prenatal care, were reviewed. Variables were compared by stratified analysis. Pearson chi 2 analysis and odd ratios (ORs) were computed. Infant mortality rate (IMR) in Chicago decreased from 17 in 1989 to 12.6 in 1995 (P < .0001). Some factors increased IMR several fold: prematurity (OR 17.43), no prenatal care (OR 4.07), inadequate weight gain (OR 2.95), African-American ethnicity (OR 2.55), and inadequate prenatal care (OR 2.03). Compared with no care, prenatal care was associated with lower IMR; however, early care was associated with higher IMR and ORs than later care. These results demonstrate prenatal care is associated with lower IMR; however, compared with late prenatal care, early care does not improve IMR. Further studies should evaluate whether improving the quality of care improves IMRs.

2015-01-01

Knowledge of the cancer burden is important for informing and advocating cancer prevention and control. Mortality data are readily available for states and counties, but not for congressional districts, from which representatives are elected and which may be more influential in compelling legislation and policy. The authors calculated average annual cancer death rates during 2002 to 2011 for each of the 435 congressional districts using mortality data from the National Center for Health Statistics and population estimates from the US Census Bureau. Age-standardized death rates were mapped for all sites combined and separately for cancers of the lung and bronchus, colorectum, breast, and prostate by race/ethnicity and sex. Overall cancer death rates vary by almost 2-fold and are generally lowest in Mountain states and highest in Appalachia and areas of the South. The distribution is similar for lung and colorectal cancers, with the lowest rates consistently noted in districts in Utah. However, for breast and prostate cancers, while the highest rates are again scattered throughout the South, the geographic pattern is less clear and the lowest rates are in Hawaii and southern Texas and Florida. Within-state heterogeneity is limited, particularly for men, with the exceptions of Texas, Georgia, and Florida. Patterns also vary by race/ethnicity. For example, the highest prostate cancer death rates are in the West and north central United States among non-Hispanic whites, but in the deep South among African Americans. Hispanics have the lowest rates except for colorectal cancer in Wyoming, eastern Colorado, and northern New Mexico. These data can facilitate cancer control and stimulate conversation about the relationship between cancer and policies that influence access to health care and the prevalence of behavioral and environmental risk factors. © 2015 American Cancer Society.

The prevalence of home birth in the United States is increasing, although its safety is undetermined. The objective of this study was to investigate the effects of obstetrical risk factors on early neonatal death in planned home births delivering at home. The authors conducted a retrospective 3-year cohort study consisting of planned home births that delivered at home in the United States between 2011 and 2013. The study excluded infants with congenital and chromosomal anomalies and infants born at ≤34 weeks' gestation. Multivariate logistic regression models were used to estimate the adjusted effects of individual obstetrical variables on early neonatal deaths within 7 days of delivery. During the study period, there were 71 704 planned and delivered home births. The overall early neonatal death rate was 1.5 deaths per 1000 planned home births. The risks of early neonatal death were significantly higher in nulliparous births (OR 2.71; 95% CI 1.71-4.31), women with a previous CS (OR 2.62, 95% CI 1.25-5.52), non-vertex presentations (OR 4.27; 95% CI 1.33-13.75), plural births (OR 9.79; 95% CI 4.25-22.57), preterm births (OR 4.68; 95% CI 2.30-9.51), and births at ≥41 weeks of gestation (OR 1.76; 95% CI 1.09-2.84). Early neonatal deaths occur more commonly in certain obstetrical contexts. Patient selection may reduce adverse neonatal outcomes among planned home births.

Adjusted hospital death rates: a potential screen for quality of medical care.

PubMed

Dubois, R W; Brook, R H; Rogers, W H

1987-09-01

Increased economic pressure on hospitals has accelerated the need to develop a screening tool for identifying hospitals that potentially provide poor quality care. Based upon data from 93 hospitals and 205,000 admissions, we used a multiple regression model to adjust the hospitals crude death rate. The adjustment process used age, origin of patient from the emergency department or nursing home, and a hospital case mix index based on DRGs (diagnostic related groups). Before adjustment, hospital death rates ranged from 0.3 to 5.8 per 100 admissions. After adjustment, hospital death ratios ranged from 0.36 to 1.36 per 100 (actual death rate divided by predicted death rate). Eleven hospitals (12 per cent) were identified where the actual death rate exceeded the predicted death rate by more than two standard deviations. In nine hospitals (10 per cent), the predicted death rate exceeded the actual death rate by a similar statistical margin. The 11 hospitals with higher than predicted death rates may provide inadequate quality of care or have uniquely ill patient populations. The adjusted death rate model needs to be validated and generalized before it can be used routinely to screen hospitals. However, the remaining large differences in observed versus predicted death rates lead us to believe that important differences in hospital performance may exist.

Reporting causes of death accurately is essential to public health and hospital-based programs; however, some U.S. studies have identified substantial inaccuracies in cause of death reporting. Using CDC's national inpatient hospital death rates as a benchmark, the Missouri Department of Health and Senior Services (DHSS) analyzed inpatient death rates reported by hospitals with high inpatient death rates in St. Louis and Kansas City metro areas. Among the selected hospitals with high inpatient death rates, 45.8% of death certificates indicated an underlying cause of death that was inconsistent with CDC's Guidelines for Death Certificate completion. Selected hospitals with high inpatient death rates were more likely to overreport heart disease and renal disease, and underreport cancer as an underlying cause of death. Based on these findings, the Missouri DHSS initiated a new web-based training module for death certificate completion based on the CDC guidelines in an effort to improve accuracy in cause of death reporting.

In recent decades, forest dieback episodes have been recorded worldwide affecting different tree species. In particular, several cases of widespread dieback and increased mortality rates have been described for Mediterranean oak (Quercus spp.) species. These dieback cases are revealing the high vulnerability of Mediterranean oaks, manifested as a loss in tree vigour (leaf shedding, canopy and shoot dieback), growth decline and sometimes tree death, as a consequence of temperatures rising at unprecedented rates and drying trends. However, in the wake of the so-called 'oak decline phenomenon', the attention on these species has generally been limited, perhaps because they are often regarded as well-adapted to the dry conditions typical of Mediterranean areas. Indeed, according to recent studies, the reduced size, the ability to sprout and the anisohydric behavior of Mediterranean oak species (reduced control of water loss and high stomatal conductance rates) would make them better adapted to withstand heat and drought stress then taller and non-sprouting isohydric species (e.g. conifer, with strict control of water loss by closing stomata). Here, we investigated the vulnerability of Mediterranean oaks by comparing neighboring living and recently dead trees in species with low (Q. pubescens), intermediate (Q. cerris, Q. frainetto) and high (Q. robur) sensitivity to water shortage. We analysed changes in tree vigour using tree-ring width and functional wood anatomical traits as proxies to search for early-warning signals of dieback, in connection with the main proposed dieback mechanisms (hydraulic failure and/or carbon starvation). We also modeled the probability of tree death as a function of tree size (diameter, height) by quantifying recent changes in growth and wood anatomy along tree-ring series. Contrary to the general concept that trees tend to experience increasing cavitation risk with increasing height, our studies show that smaller oaks are more prone to die

In 2011, critical congenital heart disease was added to the US Recommended Uniform Screening Panel for newborns, but whether state implementation of screening policies has been associated with infant death rates is unknown. To assess whether there was an association between implementation of state newborn screening policies for critical congenital heart disease and infant death rates. Observational study with group-level analyses. A difference-in-differences analysis was conducted using the National Center for Health Statistics' period linked birth/infant death data set files for 2007-2013 for 26 546 503 US births through June 30, 2013, aggregated by month and state of birth. State policies were classified as mandatory or nonmandatory (including voluntary policies and mandates that were not yet implemented). As of June 1, 2013, 8 states had implemented mandatory screening policies, 5 states had voluntary screening policies, and 9 states had adopted but not yet implemented mandates. Numbers of early infant deaths (between 24 hours and 6 months of age) coded for critical congenital heart disease or other/unspecified congenital cardiac causes for each state-month birth cohort. Between 2007 and 2013, there were 2734 deaths due to critical congenital heart disease and 3967 deaths due to other/unspecified causes. Critical congenital heart disease death rates in states with mandatory screening policies were 8.0 (95% CI, 5.4-10.6) per 100 000 births (n = 37) in 2007 and 6.4 (95% CI, 2.9-9.9) per 100 000 births (n = 13) in 2013 (for births by the end of July); for other/unspecified cardiac causes, death rates were 11.7 (95% CI, 8.6-14.8) per 100 000 births in 2007 (n = 54) and 10.3 (95% CI, 5.9-14.8) per 100 000 births (n = 21) in 2013. Early infant deaths from critical congenital heart disease through December 31, 2013, decreased by 33.4% (95% CI, 10.6%-50.3%), with an absolute decline of 3.9 (95% CI, 3.6-4.1) deaths per 100 000 births after

Determining the baseline mortality rate in a vaccinated population is necessary to be able to identify any unusual increases in deaths following vaccine administration. Background rates are particularly useful during mass immunization campaigns and in the evaluation of new vaccines. Provide background mortality rates and describe causes of death following vaccination in the Vaccine Safety Datalink (VSD). Analyses were conducted in 2012. Mortality rates were calculated at 0-1 day, 0-7 days, 0-30 days, and 0-60 days following vaccination for deaths occurring between January 1, 2005, and December 31, 2008. Analyses were stratified by age and gender. Causes of death were examined, and findings were compared to National Center for Health Statistics (NCHS) data. Among 13,033,274 vaccinated people, 15,455 deaths occurred between 0 and 60 days following vaccination. The mortality rate within 60 days of a vaccination visit was 442.5 deaths per 100,000 person-years. Rates were highest in the group aged ≥85 years, and increased from the 0-1-day to the 0-60-day interval following vaccination. Eleven of the 15 leading causes of death in the VSD and NCHS overlap in both systems, and the top four causes of death were the same in both systems. VSD mortality rates demonstrate a healthy vaccinee effect, with rates lowest in the days immediately following vaccination, most apparent in the older age groups. The VSD mortality rate is lower than that in the general U.S. population, and the causes of death are similar. Published by Elsevier Inc. on behalf of American Journal of Preventive Medicine

To investigate the quality of official neonatal death data in Maceió, Alagoas. A descriptive study was conducted on early neonatal deaths in hospitals between January 1, 2001, and December 31, 2002, to compare data entry in the Death Certificate (DC) and Mortality Information System (MIS) with a standardized form filled out with data of medical files from the mothers and newborn. The frequency with which the following variables failed to be recorded in the DC and SIM was studied: type of death, address, age of mother, gender, birth weight, and delivery type, age at death and gestational age. MIS reliability was verified using simple concordance, sensitivity and Kappa indicator. MIS recorded 451 deaths, of which 50 were excluded. Mother's age was omitted from MIS in 44.1% of cases. 85.7% to 100% of the variables not filled in for the DC were recovered from the medical files. There was good concordance between DC and medical files for type of delivery, weight and age. Birth weight and age of mother presented the least concordance between medical files and MIS. MIS presented 69.2% sensitivity for weight and 36.3% for age of mother, thus demonstrating little capability to correctly supply information to generate perinatal health indicators. Because of incomplete filling out, quality of the DC becomes precarious and makes the MIS inadequate, even though it covers 100% of neonatal deaths in Maceió. Inefficiency of the system is increased by failure of MIS technicians to correct errors found and input all the information available.

Stroke is often accompanied by hyperglycaemia, and this has an important impact on prognosis. The aim of this study was to investigate the relationship between early hyperglycaemia and the outcome of spontaneous intracerebral haemorrhage (sICH). A systematic literature search on PubMed, Embase, Cochran, WANFANG DATA, VIP and CNKI databases was conducted, and eight eligible studies were retrieved. Relative risks and 95% confidence interval (CI) in the hyperglycaemia group compared with the non-hyperglycaemia group were calculated and meta-analysed when possible. Eight controlled trials and cohort studies totalling 3756 patients addressing early hyperglycaemia and the outcome of sICH were compiled for this meta-analysis. Cut-off points for defining hyperglycaemia was 6.1-8.3 mmol/L, and the median cut-off value was 7.5 mmol/L. Studies were assigned to one of the two subgroups: the group A (for studies with the values of glucose concentrations above the median cut-off) and the group B (for studies with the values of glucose concentrations below the median cut-off). The RR for short-term death associated with hyperglycaemia was 3.65 (95% confidence interval (CI) (3.08, 4.33); P < 0.0001). In the subgroup analysis, the relative risk values were 3.46 (95% CI (1.66, 7.20); P = 0.0009) and 3.53 (95% CI (2.92, 4.26); P < 0.00001) for the groups A and B respectively. The publication bias showed that Egger's test (P > 0.1), Begg's test (P > 0.05) and Nfs0.05 exceeded included studies.

Trend (1999-2009) in U.S. death rates from myelodysplastic syndromes: utility of multiple causes of death in surveillance.

Polednak, Anthony P

2013-10-01

For myelodysplastic syndromes (MDS) (formerly known as preleukemia), a diverse group of myeloid neoplasms usually involving anemia in elderly persons, trends in U.S. death rates apparently have not been reported. Trends in annual age-standardized rates per 100,000 from 1999 to 2009 were examined for MDS using multiple causes vs. underlying cause alone, coded on death certificates for U.S. residents. The death rate (all ages combined) for MDS increased from 1999 to 2009, from 1.62 to 1.84 using underlying cause alone and from 2.89 to 3.27 using multiple causes. Rates using multiple causes were about 80% higher than those based on underlying cause alone. From 2001 to 2004 the rate for MDS using underlying cause alone (but not using multiple causes) declined, accompanied by an increase in the rate for deaths from leukemia as underlying cause with mention of MDS; this trend coincided with the advent of the 2001 World Health Organization's reclassification of certain MDS as leukemia. The MDS rate for age 65+ years increased after 2005, whereas the rate for age 25-64 years was low but declined from 2001 to 2003 and then stabilized. For deaths with MDS coded as other than underlying cause, rates did not decline for deaths from each of the two most common causes (i.e., cardiovascular diseases and leukemia). Evidence for decreases in MDS-related mortality rates was limited; the increase at age 65+ years is consistent with increases in incidence rates reported from cancer registries. Using multiple causes of death vs. only the underlying cause results in substantially higher MDS-related death rates, shows the impact of changes in the classification of myeloid neoplasms and emphasizes the importance of reducing cardiovascular disease mortality in MDS patients.

Trends in population health outcomes can be monitored to evaluate the performance of population health systems at the national, state, and local levels. The objective of this study was to compare and contrast 4 measures for assessing progress in population health improvement by using age-adjusted premature death rates as a summary measure of the overall health outcomes in the United States and in all 50 states. To evaluate the performance of statewide population health systems during the past 20 years, we used 4 measures of age-adjusted premature (<75 years of age) death rates: current rates (2009), baseline trends (1990s), follow-up trends (2000s), and changes in trends from baseline to the follow-up periods (ie, "bending the curve"). Current premature death rates varied by approximately twofold, with the lowest rate in Minnesota (268 deaths per 100,000) and the highest rate in Mississippi (482 deaths per 100,000). Rates improved the most in New York during the baseline period (-3.05% per year) and in New Jersey during the follow-up period (-2.87% per year), whereas Oklahoma ranked last in trends during both periods (-0.30%/y, baseline; +0.18%/y, follow-up). Trends improved the most in Connecticut, bending the curve downward by -1.03%; trends worsened the most in New Mexico, bending the curve upward by 1.21%. Current premature death rates, recent trends, and changes in trends vary by state in the United States. Policy makers can use these measures to evaluate the long-term population health impact of broad health care, behavioral, social, and economic investments in population health.

The prominent decline in U.S. stroke death rates observed for more than 4 decades has slowed in recent years. CDC examined trends and patterns in recent stroke death rates among U.S. adults aged ≥35 years by age, sex, race/ethnicity, state, and census region. Trends in the rates of stroke as the underlying cause of death during 2000-2015 were analyzed using data from the National Vital Statistics System. Joinpoint software was used to identify trends in stroke death rates, and the excess number of stroke deaths resulting from unfavorable changes in trends was estimated. Among adults aged ≥35 years, age-standardized stroke death rates declined 38%, from 118.4 per 100,000 persons in 2000 to 73.3 per 100,000 persons in 2015. The annual percent change (APC) in stroke death rates changed from 2000 to 2015, from a 3.4% decrease per year during 2000-2003, to a 6.6% decrease per year during 2003-2006, a 3.1% decrease per year during 2006-2013, and a 2.5% (nonsignificant) increase per year during 2013-2015. The last trend segment indicated a reversal from a decrease to a statistically significant increase among Hispanics (APC = 5.8%) and among persons in the South Census Region (APC = 4.2%). Declines in stroke death rates failed to continue in 38 states, and during 2013-2015, an estimated 32,593 excess stroke deaths might not have occurred if the previous rate of decline could have been sustained. Prior declines in stroke death rates have not continued in recent years, and substantial variations exist in timing and magnitude of change by demographic and geographic characteristics. These findings suggest the importance of strategically identifying opportunities for prevention and intervening in vulnerable populations, especially because effective and underused interventions to prevent stroke incidence and death are known to exist.

Association Between Air Temperature and Cancer Death Rates in Florida

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

The literature on suicide mortality rates in patients with cardiovascular diseases (CVDs) is limited. Taiwan National Health Insurance Research Database and Taiwan Death Registry were retrieved for patients with the 5 CVDs: congestive heart failure (CHF), acute myocardial infarction (AMI), ischemic stroke (IS), hemorrhagic stroke (HS), and pacemaker implantation (PMI) between January 1, 2001, and December 31, 2015. We excluded patients younger than 15 years old. The primary outcome was suicidal death. The standardized mortality ratio (SMR) was used to compare the risk of suicidal death in the 5 CVDs to the general population. From 2001 to 2015, there were 212,206 patients with CHF, 178,894 patients with AMI, 475,359 patients with IS, 189,555 patients with HS, and 64,173 patients with PMI. The suicide death rate per 100,000 person-year, 95% CI was 59.6 (54.5-64.8) for those with CHF, 44.6 (40.1-49.1) for AMI, 57.6 (54.7-60.5) for IS, 44.6 (40.2-49.0) for HS, 54.0 (45.9-62.0) for PMI, and 20.3 (20.1-20.4) for the general population. Patients with CHF patients had the highest SMR (2.10), followed by IS (1.96), PMI (1.86), HS (1.65), and AMI (1.46). The SMRs for patients with CVDs peaked at year 2 after the diagnosis, declined for patients with AMI, IS, and HS, increased and decreased for PMI alternately, and reached very similar values all five CVDs after 10th year after the diagnosis. Patients with acute CVD with AMI, IS, and HS had suicide death rates peaked early after diagnosis, but patients with chronic CVD with CHF and PMI had suicide death rates that increased progressively. In addition, patients with PMI, CHF, IS had highest association with psychiatric illness and patients with PMI who were of young to middle age had highest suicide death rate.

[Death rate by malnutrition in children under the age of five, Colombia].

PubMed

Quiroga, Edwin Fernando

2012-01-01

Much higher mortalities occur in children under five in developing countries with high poverty rates compared with developed countries. Causes of death are related to perinatal conditions, measles, HIV/AIDS, diarrhea, respiratory diseases and others. Throughout the world, malnutrition has been identified as the underlying cause of approximately half of these deaths. Death rate due to malnutrition was described using an adjusted method that takes into account the difficulties of identifying malnutrition as a direct cause of death. A descriptive study included analysis of the International Classification of Diseases (ICD-10) vital statistics from 2003-2007. Death rates were estimated, a method of analysis of multiple causes was applied for infectious diseases, along with calculations of death probabilities. Malnutrition was associated with infectious diseases. The frequency of infectious disease as a direct cause of death was almost seven times higher in cases with the antecedent of malnutrition. When adjusted death rate values were used, the initial value increased nearly five times. The probability of death after the adjustment for inadequate classification increased approximately four times. The Analysis of Multiple Causes Method was established as an effective method in analyzing malnutrition and infectious diesease mortality in Colombia. Malnutrition may be a direct underlying cause of death in one of eight deaths in children <1 year old and one of three deaths in 1-4-year-olds.

The increased risk for early death owing to anti-programmed cell death 1 inhibitors is a major disadvantage that requires special management. We evaluated the frequency, causes, and risk factors of early death during nivolumab treatment for non-small cell lung cancer (NSCLC) in a Japanese clinical setting. The medical records of patients with NSCLC who started receiving nivolumab between December 17, 2015 and July 31, 2016 in 3 Japanese institutes were collected. Early death was defined as any death within 3 months from the start of nivolumab treatment, irrespective of its cause. Treatment response was evaluated using the Response Evaluation Criteria In Solid Tumors criteria, version 1.1. A total of 201 patients with NSCLC were enrolled, and 38 (18.9%) died within the first 3 months. Thirty-one (81.6%) patients who experienced early death developed progressive disease, whereas 14 (36.8%) patients who experienced early death demonstrated nivolumab-induced immune-related adverse events, which required corticosteroid intervention, including interstitial lung disease in 7 (18.4%) patients. Multivariate logistic regression demonstrated that an Eastern Cooperative Oncology Group performance status score ≥ 2 (odds ratio [OR], 5.66; 95% confidence interval [CI], 2.01-15.61; P < .001), C-reactive protein-to-albumin ratio > 0.3 (OR, 10.56; 95% CI, 3.61-30.86; P < .001), and the response to prior treatment (OR, 2.07; 95% CI, 1.03-4.14; P = .041) were independent predictors for early death. Disease progression and immune-related adverse events are 2 major causes of early death with nivolumab in patients with NSCLC. An Eastern Cooperative Oncology Group performance status score ≥ 2, pretreatment C-reactive protein-to-albumin ratio > 0.3, and poor response to prior treatment were associated with early death.

The Parkinson's disease death rate: carbidopa and vitamin B6.

PubMed

Hinz, Marty; Stein, Alvin; Cole, Ted

2014-01-01

The only indication for carbidopa and benserazide is the management of L-3,4-dihydroxyphenylalanine (L-dopa)-induced nausea. Both drugs irreversibly bind to and permanently deactivate pyridoxal 5'-phosphate (PLP), the active form of vitamin B6, and PLP-dependent enzymes. PLP is required for the function of over 300 enzymes and proteins. Virtually every major system in the body is impacted directly or indirectly by PLP. The administration of carbidopa and benserazide potentially induces a nutritional catastrophe. During the first 15 years of prescribing L-dopa, a decreasing Parkinson's disease death rate was observed. Then, in 1976, 1 year after US Food and Drug Administration approved the original L-dopa/carbidopa combination drug, the Parkinson's disease death rate started increasing. This trend has continued to the present, for 38 years and counting. The previous literature documents this increasing death rate, but no hypothesis has been offered concerning this trend. Carbidopa is postulated to contribute to the increasing Parkinson's disease death rate and to the classification of Parkinson's as a progressive neurodegenerative disease. It may contribute to L-dopa tachyphylaxis.

Surveillance of US Death Rates from Chronic Diseases Related to Excessive Alcohol Use.

Polednak, Anthony P

2016-01-01

To assess the utility of multiple-cause (MC) death records for surveillance of US mortality rates from chronic causes related to excessive alcohol use. The Alcohol-Related Disease Impact (ARDI) resource produced estimates of the population 'alcohol attributable fraction' (AAF) due to excessive drinking for each alcohol-related (AAF > 0%) cause of death, and used AAFs to estimate numbers of alcohol-related deaths from alcohol-related underlying causes (UC) in adults age 20-64 and 65+ years in 2006-2010. For surveillance, this study used MC death file to identify individual deaths (2006-2010) with an 'alcohol-induced' cause (AAF = 100%) anywhere on the certificate, and to obtain US rates of premature death (ages 15-64 and 65-74 years) for 1999-2012. Using the selected MC records, numbers of deaths from alcohol-related chronic UC (2006-2010) were 81% of ARDI estimates for age 20-64, but only 40% for 65+ years. The MC records identified substantial numbers of deaths from causes (e.g. certain infectious diseases) not included as alcohol-related in ARDI, but included in surveillance of premature death rates for chronic UC. Also, premature death rates for chronic alcohol-induced causes using only the UC (as in routine mortality statistics) were only about half the rates based on MC; all rates increased in recent years but some reached statistical significance only by using MC. Using MC records underestimated total US deaths from alcohol-related chronic causes as the UC, but enhanced surveillance of rates for premature deaths involving chronic causes that may be related to excessive alcohol use. © The Author 2015.

Most studies about septic shock report a crude mortality rate that neither distinguishes between early and late deaths nor addresses the direct causes of death. We herein aimed to determine the modalities of death in septic shock. This was a 6-year (2008-2013) monocenter retrospective study. All consecutive patients diagnosed for septic shock within the first 48 h of intensive care unit (ICU) admission were included. Early and late deaths were defined as occurring within or after 3 days following ICU admission, respectively. The main cause of death in the ICU was determined from medical files. A multinomial logistic regression analysis using the status alive as the reference category was performed to identify the prognostic factors associated with early and late deaths. Five hundred forty-three patients were included, with a mean age of 66 ± 15 years and a high proportion (67 %) of comorbidities. The in-ICU and in-hospital mortality rates were 37.2 and 45 %, respectively. Deaths occurred early for 78 (32 %) and later on for 166 (68 %) patients in the ICU (n = 124) or in the hospital (n = 42). Early deaths were mainly attributable to intractable multiple organ failure related to the primary infection (82 %) and to mesenteric ischemia (6.4 %). In-ICU late deaths were directly related to end-of-life decisions in 29 % of patients and otherwise mostly related to ICU-acquired complications, including nosocomial infections (20.4 %) and mesenteric ischemia (16.6 %). Independent determinants of early death were age, malignancy, diabetes mellitus, no pathogen identification, and initial severity. Among 3-day survivors, independent risk factors for late death were age, cirrhosis, no pathogen identification, and previous corticosteroid treatment. Our study provides a comprehensive assessment of septic shock-related deaths. Identification of risk factors of early and late deaths may determine differential prognostic patterns.

The aim of the following work was to assess three-level selective perinatal care in Polish voivodeships in 2008 on the basis of the following parameters: birth rates as well as perinatal death rates, divided into three classes of neonatal weights, in hospitals on each of the three levels. The goal of selective perinatal care is, among other things, to diagnose threats to the mother and/or fetus and direct women with high-risk pregnancies to higher level obstetrics and neonatology clinics and units. The structure of a regional three-level perinatal care, as well as the rules and procedures governing the process of redirecting patients to different levels of perinatal care have been defined in great detail. Perinatal death rates analysis has been carried out on the basis of data received from Voivodeship Public Health Centers in sixteen voivodeships in Poland in 2008. The main document constituted MZ-29 form section X, modified by the authors and subdivided into levels of perinatal care. All data contained in the form have been verified: the numbers concerning birth and death rates as well as perinatal deaths and birth weight subgroups from given voivodeship hospitals. Statistic analysis was limited to the presentation of result tables and graphs within voivodeships. Birth rates and perinatal death rates revealed that in the course of ten years the level of perinatal care, introduced gradually in Poland between the years 1997-1999, resulted in its improvement. Perinatal death rates decreased in the course of ten years from 9.5% in 1999 to 6.45% in 2008, i.e. by 0.3% annually. On the first level, the rate of neonates with very low birth weight, 500-999g, decreased by 5.5% and was 21.1% in 2008 and 36.6% in 1999, whereas on the third level, the birth rate in the same group (500-999g) increased by 12.7% and was 47.7% in 2008 and 35.5% in 1999. There is a growing and alarming tendency to perform cesarean sections. The increase amounted up to 1.2% annually (18.2% in 19999

To evaluate the preventability of the traumatic deaths in patients who were admitted to neurosurgery department, we performed this study. A retrospective review identified 52 patients who admitted to neurosurgery department with severe traumatic brain injuries between 2013 and 2014. Based on radiologic and clinical state at emergency room, each preventability of death was estimated by professional panel discussion. And the final death rates were calculated. The preventable and potentially preventable traumatic death rates was 19.2% in this study. This result is lower than that of the research of 2012, Korean preventable and potentially preventable traumatic death rates. The rate of preventable and potentially preventable traumatic death of operation group is lower than that of conservative treatment group. Also, we confirmed that direct transfer and the time to operation are important to reduce the preventability. We report the preventable and potentially preventable traumatic death rates of our institute for evaluation of preventability in severe traumatic brain injuries during the last 2 years. For decrease of preventable death, we suggest that continuous survey of the death rate of traumatic brain injury patients is required.

To examine trends in death rates for hyperglycemic crisis (diabetic ketoacidosis or hyperglycemic hyperosmolar state) among adults with diabetes in the U.S. from 1985 to 2002. Deaths with hyperglycemic crisis as the underlying cause were identified from national mortality data. Death rates were calculated using estimates of adults with diabetes from the National Health Interview Survey as the denominator and age adjusted to the 2000 U.S. population. The trends from 1985 to 2002 were tested using joinpoint regression analysis. Deaths due to hyperglycemic crisis dropped from 2,989 in 1985 to 2,459 in 2002. During the time period, age-adjusted death rates decreased from 42.4 to 23.8 per 100,000 adults with diabetes (4.4% decrease per year, P for trend <0.01). Death rates declined in all age-groups, with the greatest decrease occurring among individuals aged > or =65 years. Age-adjusted death rates fell for all race-sex subgroups, with black men experiencing the smallest decline. About one-fifth of deaths occurred at home or on arrival at the hospital, and the death rates for hyperglycemic crisis occurring at these places declined only modestly over time (2.1% decrease per year, P for trend = 0.049). Overall death rates due to hyperglycemic crisis among adults with diabetes have declined in the U.S. However, scope for further improvement remains, especially to further reduce death rates among black men and to prevent deaths occurring at home.

Dictyostelium cell death: early emergence and demise of highly polarized paddle cells.

2003-03-31

Cell death in the stalk of Dictyostelium discoideum, a prototypic vacuolar cell death, can be studied in vitro using cells differentiating as a monolayer. To identify early events, we examined potentially dying cells at a time when the classical signs of Dictyostelium cell death, such as heavy vacuolization and membrane lesions, were not yet apparent. We observed that most cells proceeded through a stereotyped series of differentiation stages, including the emergence of "paddle" cells showing high motility and strikingly marked subcellular compartmentalization with actin segregation. Paddle cell emergence and subsequent demise with paddle-to-round cell transition may be critical to the cell death process, as they were contemporary with irreversibility assessed through time-lapse videos and clonogenicity tests. Paddle cell demise was not related to formation of the cellulose shell because cells where the cellulose-synthase gene had been inactivated underwent death indistinguishable from that of parental cells. A major subcellular alteration at the paddle-to-round cell transition was the disappearance of F-actin. The Dictyostelium vacuolar cell death pathway thus does not require cellulose synthesis and includes early actin rearrangements (F-actin segregation, then depolymerization), contemporary with irreversibility, corresponding to the emergence and demise of highly polarized paddle cells.

Associations between Periodontal Microbiota and Death Rates.

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.

Violent death is a serious problem in the United States. Previous research showing US rates of violent death compared with other high-income countries used data that are more than a decade old. We examined 2010 mortality data obtained from the World Health Organization for populous, high-income countries (n = 23). Death rates per 100,000 population were calculated for each country and for the aggregation of all non-US countries overall and by age and sex. Tests of significance were performed using Poisson and negative binomial regressions. US homicide rates were 7.0 times higher than in other high-income countries, driven by a gun homicide rate that was 25.2 times higher. For 15- to 24-year-olds, the gun homicide rate in the United States was 49.0 times higher. Firearm-related suicide rates were 8.0 times higher in the United States, but the overall suicide rates were average. Unintentional firearm deaths were 6.2 times higher in the United States. The overall firearm death rate in the United States from all causes was 10.0 times higher. Ninety percent of women, 91% of children aged 0 to 14 years, 92% of youth aged 15 to 24 years, and 82% of all people killed by firearms were from the United States. The United States has an enormous firearm problem compared with other high-income countries, with higher rates of homicide and firearm-related suicide. Compared with 2003 estimates, the US firearm death rate remains unchanged while firearm death rates in other countries decreased. Thus, the already high relative rates of firearm homicide, firearm suicide, and unintentional firearm death in the United States compared with other high-income countries increased between 2003 and 2010.

Estimation of death rates in US states with small subpopulations.

Voulgaraki, Anastasia; Wei, Rong; Kedem, Benjamin

2015-05-20

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.

Use and misuse of motor-vehicle crash death rates in assessing highway-safety performance.

PubMed

O'Neill, Brian; Kyrychenko, Sergey Y

2006-12-01

The objectives of the article are to assess the extent to which comparisons of motor-vehicle crash death rates can be used to determine the effectiveness of highway-safety policies over time in a country or to compare policy effectiveness across countries. Motor-vehicle crash death rates per mile traveled in the 50 U.S. states from 1980 to 2003 are used to show the influence on these rates of factors independent of highway-safety interventions. Multiple regression models relating state death rates to various measures related to urbanization and demographics are used. The analyses demonstrate strong relationships between state death rates and urbanization and demographics. Almost 60% of the variability among the state death rates can be explained by the independent variables in the multiple regression models. When the death rates for passenger vehicle occupants (i.e., excluding motorcycle, pedestrian, and other deaths) are used in the regression models, almost 70% of the variability in the rates can be explained by urbanization and demographics. The analyses presented in the article demonstrate that motor-vehicle crash death rates are strongly influenced by factors unrelated to highway-safety countermeasures. Overall death rates should not be used as a basis for judging the effectiveness (or ineffectiveness) of specific highway-safety countermeasures or to assess overall highway-safety policies, especially across jurisdictions. There can be no substitute for the use of carefully designed scientific evaluations of highway-safety interventions that use outcome measures directly related to the intervention; e.g., motorcyclist deaths should be used to assess the effectiveness of motorcycle helmet laws. While this may seem obvious, there are numerous examples in the literature of death rates from all crashes being used to assess the effectiveness of interventions aimed at specific subsets of crashes.

Objectives Early parental death is associated with lifelong tendencies toward depression and chronic stress. We tested the hypothesis that, early parental death is associated with higher risk for Alzheimer’s disease (AD) in offspring. Design A population-based epidemiological study of dementia with detailed clinical evaluations, linked to one of the world’s richest sources of objective genealogical and vital statistics data. Setting Home visits with residents of a rural county in northern Utah. Participants 4,108 subjects, aged 65-105. Measurements Multi-stage dementia ascertainment protocol implemented in four triennial waves, yielding expert consensus diagnoses of 570 participants with AD and 3,538 without dementia. Parental death dates, socioeconomic status and parental remarriage after widowhood were obtained from the Utah Population Database, a large genealogical database linked to statewide birth and death records. Results Mother’s death during subject’s adolescence was significantly associated with higher rate of AD in regression models that included age, gender, education, APOE genotype, and socioeconomic status. Father’s death before subject age 5 showed a weaker association. In stratified analyses, associations were significant only when the widowed parent did not remarry. Parental death associations were not moderated by gender or APOE genotype. Findings were specific to AD and not found for non-AD dementia. Conclusions Parental death during childhood is associated with higher prevalence of AD, with different critical periods for father’s vs. mother’s death, with strength of these associations attenuated by remarriage of the widowed parent.

Objective To determine whether high-volume hospitals (HVHs) have lower in-hospital death rates after abdominal aortic aneurysm (AAA) repair compared with low-volume hospitals (LVHs). Summary Background Data Select statewide studies have shown that HVHs have superior outcomes compared with LVHs for AAA repair, but they may not be representative of the true volume–outcome relationship for the entire United States. Methods Patients undergoing repair of intact or ruptured AAAs in the Nationwide Inpatient Sample (NIS) for 1996 and 1997 were included (n = 13,887) for study. The NIS represents a 20% stratified random sample representative of all U.S. hospitals. Unadjusted and case mix-adjusted analyses were performed. Results The overall death rate was 3.8% for intact AAA repair and 47% for ruptured AAA repair. For repair of intact AAAs, HVHs had a lower death rate than LVHs. The death rate after repair of ruptured AAA was also slightly lower at HVHs. In a multivariate analysis adjusting for case mix, having surgery at an LVH was associated with a 56% increased risk of in-hospital death. Other independent risk factors for in-hospital death included female gender, age older than 65 years, aneurysm rupture, urgent or emergent admission, and comorbid disease. Conclusions This study from a representative national database documents that HVHs have a significantly lower death rate than LVHs for repair of both intact and ruptured AAA. These data support the regionalization of patients to HVHs for AAA repair. PMID:11923615

Rates and correlates of undetermined deaths among African Americans: results from the National Violent Death Reporting System.

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. © 2012 The American Association of Suicidology.

[Sudden cardiac death out of the hospital and early defibrillation].

2000-06-01

Since most sudden cardiac death victims show neither symptoms before the event nor other signs or risk factors that would have identified them as a high risk population before their cardiac arrest, emergency out-of-hospital medical services must be improved in order to obtain a higher survival in these patients. Early defibrillation is an essential part of the chain of survival that also includes the early identification of the victim, activation of the emergency medical system, immediate arrival of trained personnel who can perform basic cardiopulmonary resuscitation and early initiation of advanced cardiac life support that would raise the survival rate for sudden cardiac arrest victims. Many studies have demonstrated the enormous importance of early defibrillation in patients with a cardiac arrest due to ventricular fibrillation. The most important predictor of survival in these individuals is the time that elapses until electric defibrillation, the longer the time to defbrillation the lower the number of patients who are eventually discharged. Multiple studies have demonstrated that automatic external defibrillation will reduce the time elapsed to defibrillation and thus improve survival. For these reason, public access defibrillation to allow the use of automatic external defibrillators by minimally trained members of the lay public, has received increasing interest on the part of a groving number of companies, cities or countries. The automatic external defibrillaton, as performed by a lay person is being investigated. The liberalization of its application, if is demonstrated to be effective, will need to be accompanied by legal measures to endorse it and appropriate health education, probably during secondary education.

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

Gross, Samuel R.; O’Brien, Barbara; Hu, Chen; Kennedy, Edward H.

2014-01-01

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

Stillbirth, early death and neonatal morbidity among offspring of female cancer survivors.

Increased awareness of the adverse effects of cancer treatments has prompted the development of fertility preserving regimens for the growing population of cancer survivors who desire to have children of their own. We conducted a registry-based study to evaluate the risk of stillbirth, early death and neonatal morbidity among children of female cancer survivors (0-34 years at diagnosis) compared with children of female siblings. A total of 3501 and 16 908 children of female cancer patients and siblings, respectively, were linked to the national medical birth and cause-of-death registers. The risk of stillbirth or early death was not significantly increased among offspring of cancer survivors as compared to offspring of siblings: the risk [Odds Ratio (OR)] of early neonatal death, i.e. mortality within the first week was 1.35, with a 95% confidence interval (CI) of 0.58-3.18, within 28 days 1.40, 95% CI 0.46-4.24 and within the first year of life 1.11, 95% CI 0.64-1.93 after adjustment for the main explanatory variables. All these risk estimates were reduced towards one after further adjustment for duration of pregnancy. Measures of serious neonatal morbidity were not significantly increased among the children of survivors. However, there was a significant increase in the monitoring of children of cancer survivors for neonatal conditions (OR 1.56, 95% CI 1.35-1.80), which persisted even after correcting for duration of pregnancy, that might be related to parental cancer and its treatment or increased surveillance among the children. Offspring of cancer survivors were more likely to require monitoring or care in a neonatal intensive care unit, but the risk of early death or stillbirth was not increased after adjustment for prematurity. Due to the rarity of the mortality outcomes studied, collaborative studies may be helpful in ruling out the possibility of an increased risk among offspring of cancer survivors.

Heart Disease Death Rates in Low Versus High Land Elevation Counties in the U.S.

PubMed

Hart, John

2015-01-01

Previous research on land elevation and cancer death rates in the U.S. revealed lower cancer death rates in higher elevations. The present study further tests the possible effect of land elevation on a diffident health outcome, namely, heart disease death rates. U.S. counties not overlapping in their land elevations according to their lowest and highest elevation points were identified. Using an ecological design, heart disease death rates for two races (black and white) corresponding to lower elevation counties were compared to heart disease death rates in higher land elevation counties using the two-sample t-test and effect size statistics. Death rates in higher land elevation counties for both races were lower compared to the death rates in lower land elevation counties (p < 0.001) with large effect sizes (of > 0.70). Since this is an observational study, no causal inference is claimed, and further research is indicated to verify these findings.

Introduction The prominent decline in U.S. stroke death rates observed for more than 4 decades has slowed in recent years. CDC examined trends and patterns in recent stroke death rates among U.S. adults aged ≥35 years by age, sex, race/ethnicity, state, and census region. Methods Trends in the rates of stroke as the underlying cause of death during 2000–2015 were analyzed using data from the National Vital Statistics System. Joinpoint software was used to identify trends in stroke death rates, and the excess number of stroke deaths resulting from unfavorable changes in trends was estimated. Results Among adults aged ≥35 years, age-standardized stroke death rates declined 38%, from 118.4 per 100,000 persons in 2000 to 73.3 per 100,000 persons in 2015. The annual percent change (APC) in stroke death rates changed from 2000 to 2015, from a 3.4% decrease per year during 2000–2003, to a 6.6% decrease per year during 2003–2006, a 3.1% decrease per year during 2006–2013, and a 2.5% (nonsignificant) increase per year during 2013–2015. The last trend segment indicated a reversal from a decrease to a statistically significant increase among Hispanics (APC = 5.8%) and among persons in the South Census Region (APC = 4.2%). Declines in stroke death rates failed to continue in 38 states, and during 2013–2015, an estimated 32,593 excess stroke deaths might not have occurred if the previous rate of decline could have been sustained. Conclusions and Implications for Public Health Practice Prior declines in stroke death rates have not continued in recent years, and substantial variations exist in timing and magnitude of change by demographic and geographic characteristics. These findings suggest the importance of strategically identifying opportunities for prevention and intervening in vulnerable populations, especially because effective and underused interventions to prevent stroke incidence and death are known to exist.

To describe congenital heart disease death rates in infants born between 34 and 40 weeks, estimate the relationship between gestational age and congenital heart disease infant death rates, and compare congenital heart disease death rates across 1- and 2-week intervals in gestational age. The 2000 to 2003 national linked birth/infant death cohort datasets were obtained. Congenital heart disease deaths were identified by using International Statistical Classification of Diseases, 10th Revision codes. Proportional death rates were calculated by using congenital heart disease deaths and all live births. The relationship between congenital heart disease death rates and gestational age was determined. Death rates were compared across intervals. A total of 14.9 million records were analyzed. Congenital heart disease deaths occurred in 4736 infants (0.04%) born between 34 and 40 weeks. There was a significant, negative linear relationship between congenital heart disease death rate and gestational age (R(2) = 0.97). Comparisons across 1-week intervals varied (P = .02-.23). All 2-week intervals were statistically significant (P < .01). Congenital heart disease death rates decrease as gestational age approaches 40 weeks. These results should be considered before elective delivery for the sole indication of prenatally diagnosed congenital heart disease. Copyright © 2011 Mosby, Inc. All rights reserved.

Widening of Socioeconomic Inequalities in U.S. Death Rates, 1993–2001

2008-01-01

Background Socioeconomic inequalities in death rates from all causes combined widened from 1960 until 1990 in the U.S., largely because cardiovascular death rates decreased more slowly in lower than in higher socioeconomic groups. However, no studies have examined trends in inequalities using recent US national data. Methodology/Principal Findings We calculated annual age-standardized death rates from 1993–2001 for 25–64 year old non-Hispanic whites and blacks by level of education for all causes and for the seven most common causes of death using death certificate information from 43 states and Washington, D.C. Regression analysis was used to estimate annual percent change. The inequalities in all cause death rates between Americans with less than high school education and college graduates increased rapidly from 1993 to 2001 due to both significant decreases in mortality from all causes, heart disease, cancer, stroke, and other conditions in the most educated and lack of change or increases among the least educated. For white women, the all cause death rate increased significantly by 3.2 percent per year in the least educated and by 0.7 percent per year in high school graduates. The rate ratio (RR) comparing the least versus most educated increased from 2.9 (95% CI, 2.8–3.1) in 1993 to 4.4 (4.1–4.6) in 2001 among white men, from 2.1 (1.8–2.5) to 3.4 (2.9–3–9) in black men, and from 2.6 (2.4–2.7) to 3.8 (3.6–4.0) in white women. Conclusion Socioeconomic inequalities in mortality are increasing rapidly due to continued progress by educated white and black men and white women, and stable or worsening trends among the least educated.

This ecological study aimed i) to quantify the association of age and gender with the three components of pedestrians' death rates after a pedestrian-vehicle crash: exposure, risk of crash and fatality, and ii) to determine the contribution of each component to differences in death rates according to age and gender in Spain. We analyzed data for 220 665 pedestrians involved in road crashes recorded in the Spanish registry of road crashes with victims from 1993 to 2011, and a subset of 39 743 pedestrians involved in clean collisions (in which the pedestrian did not commit an infraction). Using decomposition and quasi-induced exposure methods, we obtained the proportion of increase in death rates for each age and gender group associated with exposure, risk of collision and fatality. Death rates increased with age. The main contributor to this increase was fatality, although exposure also increased with age. In contrast, the risk of collision decreased with age. Males had higher death rates than females, especially in the 24-54 year old group. Higher fatality rates in males were the main determinant of this difference, which was also related with a higher risk of collision in males. However, exposure rates were higher in females. The magnitude and direction of the associations between age and gender and each of the three components of pedestrians' death rates differed depending on the specific component explored. These differences need to be taken into account in order to prioritize preventive strategies intended to decrease mortality among pedestrians.

The Parkinson’s disease death rate: carbidopa and vitamin B6

PubMed Central

Hinz, Marty; Stein, Alvin; Cole, Ted

2014-01-01

The only indication for carbidopa and benserazide is the management of L-3,4-dihydroxyphenylalanine (L-dopa)-induced nausea. Both drugs irreversibly bind to and permanently deactivate pyridoxal 5′-phosphate (PLP), the active form of vitamin B6, and PLP-dependent enzymes. PLP is required for the function of over 300 enzymes and proteins. Virtually every major system in the body is impacted directly or indirectly by PLP. The administration of carbidopa and benserazide potentially induces a nutritional catastrophe. During the first 15 years of prescribing L-dopa, a decreasing Parkinson’s disease death rate was observed. Then, in 1976, 1 year after US Food and Drug Administration approved the original L-dopa/carbidopa combination drug, the Parkinson’s disease death rate started increasing. This trend has continued to the present, for 38 years and counting. The previous literature documents this increasing death rate, but no hypothesis has been offered concerning this trend. Carbidopa is postulated to contribute to the increasing Parkinson’s disease death rate and to the classification of Parkinson’s as a progressive neurodegenerative disease. It may contribute to L-dopa tachyphylaxis. PMID:25364278

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

Altered bone structure and function contribute to the high rates of fractures in dialysis patients compared to the general population. Fracture events may increase the risk of subsequent adverse clinical outcomes. Here we assessed the incidence of post-fracture morbidity and mortality in an international cohort of 34,579 in-center hemodialysis patients in the Dialysis Outcomes and Practice Patterns Study (DOPPS). We estimated country-specific rates of fractures requiring a hospital admission and associated length of stay in the hospital. Incidence rates of death and of a composite event of death/rehospitalization were estimated for 1 year after fracture. Overall, 3% of participants experienced a fracture. Fracture incidence varied across countries, from 12 events/1000 patient-years (PY) in Japan to 45/1000 PY in Belgium. In all countries, fracture rates were higher in the hemodialysis group compared to those reported for the general population. Median length of stay ranged from 7 to 37 days in the United States and Japan, respectively. In most countries, postfracture mortality rates exceeded 500/1000 PY and death/rehospitalization rates exceeded 1500/1000 PY. Fracture patients had higher unadjusted rates of death (3.7-fold) and death/rehospitalization (4.0-fold) compared to the overall DOPPS population. Mortality and hospitalization rates were highest in the first month after the fracture and declined thereafter. Thus, the high frequency of fractures and increased adverse outcomes following a fracture pose a significant health burden for dialysis patients. Fracture prevention strategies should be identified and applied broadly in nephrology practices.

Kyrychenko, Sergey Y; McCartt, Anne T

2006-03-01

Effective July 1, 2000, Florida's universal helmet law was amended to exclude riders ages 21 and older with insurance coverage providing at least 10,000 US dollars in medical benefits for injuries sustained in a motorcycle crash. Observed helmet use in Florida was reported to have declined from nearly 100% in 1998, before the law change, to 53% after. This study examined the effects of the law change on the likelihood of death, given involvement in a motorcycle crash. Rates of motorcyclist deaths per crash involvement in Florida for 2001-2002 (after the law change) were compared with those for 1998-1999 (before the law change). Before/after death rate ratios (95% CIs) were examined, and logistic regression models estimated the effect of the helmet law change on the odds of death in a crash, while controlling for rider gender, age, and seating position, and number of vehicles. The motorcyclist death rate increased significantly after the law change, from 30.8 to 38.8 deaths per 1,000 crash involvements. Motorcyclist death rates increased for single- and multiple-vehicle crashes, for male and female operators, and for riders of all ages including those younger than 21. After controlling for gender and age, the likelihood of death given involvement in a motorcycle crash was 25% higher than expected after the law change. It is estimated that 117 motorcyclist deaths could have been avoided during 2001-2002 if Florida's universal helmet law had remained in place. This study provides evidence of the life-saving benefits of universal helmet laws. The results also suggest that age-specific helmet laws are not effective in protecting the youngest drivers. This is not surprising, as these laws are largely unenforceable.

Nonlinear fluctuations-induced rate equations for linear birth-death processes

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.

The stillbirth rate in most high income countries reduced in the early part of the 20(th) century but has apparently been static over the past 2½ decades. However, there has not been any account taken of pregnancy terminations and birth defects on these trends. The current study sought to quantify these relationships using linked Western Australian administrative data for the years 1986-2010. We analysed a retrospective, population-based cohort of Western Australia births from 1986 to 2010, with de-identified linked data from core population health datasets. The study revealed a significant decrease in the neonatal death rate from 1986 to 2010 (6.1 to 2.1 neonatal deaths per 1000 births; p < .01), while the overall stillbirth rate remained static. The stillbirth trend was driven by deaths in the extremely preterm period (20-27 weeks; which account for about half of all recorded stillbirths and neonatal deaths), masking significant decreases in the rate of stillbirth at very preterm (28-31 weeks), moderate to late preterm (32-36 weeks), and term (37+ weeks). For singletons, birth defects made up an increasing proportion of stillbirths and decreasing proportion of neonatal deaths over the study period-a shift that appears to have been largely driven by the increase in late pregnancy terminations (20 weeks or more gestation). After accounting for pregnancy terminations, we observed a significant downward trend in stillbirth and neonatal death rates at every gestational age. Changes in clinical practice related to pregnancy terminations have played a substantial role in shaping stillbirth and neonatal death rates in Western Australia over the 2½ decades to 2010. The study underscores the need to disaggregate perinatal mortality data in order to support a fuller consideration of the influence of pregnancy terminations and birth defects when assessing change over time in the rates of stillbirth and neonatal death.

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

PubMed

2016-09-16

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.

Following recent improvements in the curability of oral cancer, chronological shifts and changes in the causes of death after treatment have been observed. We conducted a review of the post-treatment causes of death following radiotherapy for oral cancers. The medical records of 966 patients with early-stage (stage I and II) oral cancer treated at our institute between 1980 and 2001 were reviewed, and the chronological shifts and changes in the causes of death after radiotherapy were assessed. Of the 966 patients enrolled in this study, 365 have died to date. Two hundred and eleven patients died of their primary malignancy; 193 of these deaths occurred within 5 years of treatment for the primary oral cancer. The second most frequent cause of death was second primary cancer (n = 90). Twenty-three patients with head and neck cancers and 18 patients with esophageal cancers died within 10 years of radiotherapy, and six patients with lung cancers died after more than 10 years. Within the first 5 years following treatment, the major cause of death was the primary oral cancer. After 5-10 years, a second primary cancer, such as head and neck cancer or esophageal cancer, became the leading cause of death. Over a 10-year period, the proportion of deaths from a second primary cancer in the lung was significant. We have demonstrated that there are chronological shifts and changes in the causes of death following treatment for early-stage oral cancer.

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

Inaccuracies in oral cavity-pharynx cancer coded as the underlying cause of death on U.S. death certificates, and trends in mortality rates (1999-2010).

2014-08-01

To enhance surveillance of mortality from oral cavity-pharynx cancer (OCPC) by considering inaccuracies in the cancer site coded as the underlying cause of death on death certificates vs. cancer site in a population-based cancer registry (as the gold standard). A database was used for 9 population-based cancer registries of the Surveillance, Epidemiology and End Results (SEER) Program, including deaths in 1999-2010 for patients diagnosed in 1973-2010. Numbers of deaths and death rates for OCPC in the SEER population were modified for apparent inaccuracies in the cancer site coded as the underlying cause of death. For age groups <65 years, deaths from OCPC were underestimated by 22-35% by using unmodified (vs. modified) numbers, but temporal declines in death rates were still evident in the SEER population and were similar to declines using routine mortality data for the entire U.S. population. Deaths were underestimated by about 70-80% using underlying cause for tonsillar cancers, strongly associated with human papillomavirus (HPV) infection, but a lack of decline in death rates was still evident. Routine mortality statistics based on underlying cause of death underestimate OCPC deaths but demonstrate trends in OCPC death rates that require continued surveillance in view of increasing incidence rates for HPV-related OCPC.

Death and population dynamics affect mutation rate estimates and evolvability under stress in bacteria

PubMed Central

Bonhoeffer, Sebastian

2018-01-01

The stress-induced mutagenesis hypothesis postulates that in response to stress, bacteria increase their genome-wide mutation rate, in turn increasing the chances that a descendant is able to better withstand the stress. This has implications for antibiotic treatment: exposure to subinhibitory doses of antibiotics has been reported to increase bacterial mutation rates and thus probably the rate at which resistance mutations appear and lead to treatment failure. More generally, the hypothesis posits that stress increases evolvability (the ability of a population to generate adaptive genetic diversity) and thus accelerates evolution. Measuring mutation rates under stress, however, is problematic, because existing methods assume there is no death. Yet subinhibitory stress levels may induce a substantial death rate. Death events need to be compensated by extra replication to reach a given population size, thus providing more opportunities to acquire mutations. We show that ignoring death leads to a systematic overestimation of mutation rates under stress. We developed a system based on plasmid segregation that allows us to measure death and division rates simultaneously in bacterial populations. Using this system, we found that a substantial death rate occurs at the tested subinhibitory concentrations previously reported to increase mutation rate. Taking this death rate into account lowers and sometimes removes the signal for stress-induced mutagenesis. Moreover, even when antibiotics increase mutation rate, we show that subinhibitory treatments do not increase genetic diversity and evolvability, again because of effects of the antibiotics on population dynamics. We conclude that antibiotic-induced mutagenesis is overestimated because of death and that understanding evolvability under stress requires accounting for the effects of stress on population dynamics as much as on mutation rate. Our goal here is dual: we show that population dynamics and, in particular, the

Pedestrians are the most vulnerable group to accidents among road users. Due to the well-known concerns and complications of accidents involving pedestrians, the aim of this study was to identify the rate of such accidents for five-year period. We analyzed all fatalities among pedestrians caused by traffic accidents during years of 2009-2013 in Fars Province in Iran. The study was a cross-sectional study in which logistic regression analysis was used to predict the death rate among pedestrians. Sensitivity analysis using the Monte Carlo method was used to increase the accuracy of the results. Then, we predicted the death rates for the years 2014-2018 predicted and compared the results with the actual data from the previous five-year period (2009-2013). During 2009-2013, 1723 out of 8689 (20.3%) of the people killed in traffic accidents were pedestrians. The death rate for male pedestrians in 2011 was estimated to be 10.86 per 100,000 (with an uncertainty interval of 95% giving a range of 9.85-12.05 per 100,000). Compared to the data for 2006, this represented a decrease of 20% (with a mean decrease of 4% per year). Based on these data, the death date in 2018n was projected to be 8.08 per 100,000 (with an uncertainty interval of 95% giving a range of 7.26-8.87). Similar data and analysis for women indicated that the reduction in the rate of fatalities has been smaller than that for men in recent years, i.e., 2.2% versus 4%. Although great progress has been made in reducing traffic accidents, to date, the death rate is still high among pedestrians. It is essential to continue to find ways to reduce traffic accidents and the pedestrians' deaths associated with them, especially among the elderly, who make up a disproportionate fraction of the deaths.

Early induction of c-Myc is associated with neuronal cell death.

Neuronal cell cycle activation has been implicated in neurodegenerative diseases such as Alzheimer's disease, while the initiating mechanism of cell cycle activation remains to be determined. Interestingly, our previous studies have shown that cell cycle activation by c-Myc (Myc) leads to neuronal cell death which suggests Myc might be a key regulator of cell cycle re-entry mediated neuronal cell death. However, the pattern of Myc expression in the process of neuronal cell death has not been addressed. To this end, we examined Myc induction by the neurotoxic agents camptothecin and amyloid-β peptide in a differentiated SH-SY5Y neuronal cell culture model. Myc expression was found to be significantly increased following either treatment and importantly, the induction of Myc preceded neuronal cell death suggesting it is an early event of neuronal cell death. Since ectopic expression of Myc in neurons causes the cell cycle activation and neurodegeneration in vivo, the current data suggest that induction of Myc by neurotoxic agents or other disease factors might be a key mediator in cell cycle activation and consequent cell death that is a feature of neurodegenerative diseases.

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.

Heart disease is the leading cause of death in the United States. In 2015, heart disease accounted for approximately 630,000 deaths, representing one in four deaths in the United States. Although heart disease death rates decreased 68% for the total population from 1968 to 2015, marked disparities in decreases exist by race and state. 1968-2015. The National Vital Statistics System (NVSS) data on deaths in the United States were abstracted for heart disease using diagnosis codes from the eighth, ninth, and tenth revisions of the International Classification of Diseases (ICD-8, ICD-9, and ICD-10) for 1968-2015. Population estimates were obtained from NVSS files. National and state-specific heart disease death rates for the total population and by race for adults aged ≥35 years were calculated for 1968-2015. National and state-specific black-white heart disease mortality ratios also were calculated. Death rates were age standardized to the 2000 U.S. standard population. Joinpoint regression was used to perform time trend analyses. From 1968 to 2015, heart disease death rates decreased for the total U.S. population among adults aged ≥35 years, from 1,034.5 to 327.2 per 100,000 population, respectively, with variations in the magnitude of decreases by race and state. Rates decreased for the total population an average of 2.4% per year, with greater average decreases among whites (2.4% per year) than blacks (2.2% per year). At the national level, heart disease death rates for blacks and whites were similar at the start of the study period (1968) but began to diverge in the late 1970s, when rates for blacks plateaued while rates for whites continued to decrease. Heart disease death rates among blacks remained higher than among whites for the remainder of the study period. Nationwide, the black-white ratio of heart disease death rates increased from 1.04 in 1968 to 1.21 in 2015, with large increases occurring during the 1970s and 1980s followed by small but steady

The aim of the present study was to develop criteria to identify sudden cardiac death (SCD) and estimate population rates of SCD using administrative mortality and hospital morbidity records in Western Australia. Four criteria were developed using place, death within 24 h, principal and secondary diagnoses, underlying and associated cause of death, and/or occurrence of a post mortem to identify SCD. Average crude, age-standardised and age-specific rates of SCD were estimated using population person-linked administrative data. In all, 9567 probable SCDs were identified between 1997 and 2010, with one-third aged ≥ 35 years having no prior admission for cardiovascular disease. SCD was more frequent in men (62.1%). The estimated average annual crude SCD rate for the period was 34.6 per 100 000 person-years with an average annual age-standardised rate of 37.8 per 100 000 person-years. Age-specific standardised rates were 1.1 per 100 000 person-years and 70.7 per 100 000 person-years in people aged 1-34 and ≥ 35 years, respectively. Ischaemic heart disease (IHD) was recorded as the underlying cause of death in approximately 80% of patients aged ≥ 35 years, followed by valvular heart disease and heart failure. IHD was the most common cause of death in those aged 1-34 years, followed by unspecified cardiomyopathy and dysrhythmias. Administrative morbidity and mortality data can be used to estimate rates of SCD and therefore provide a suitable methodology for monitoring SCD over time. The findings highlight the magnitude of SCD and its potential for public health prevention.

We tested whether local cultural and social values regarding the use of health care are associated with the likelihood of home death, using variation in local rates of home births as a proxy for geographic variation in these values. For each of 351110 adult decedents in Washington state who died from 1989 through 1998, we calculated the home birth rate in each zip code during the year of death and then used multivariate regression modeling to estimate the relation between the likelihood of home death and the local rate of home births. Individuals residing in local areas with higher home birth rates had greater adjusted likelihood of dying at home (odds ratio [OR]=1.04 for each percentage point increase in home birth rate; 95% confidence interval [CI] = 1.03, 1.05). Moreover, the likelihood of dying at home increased with local wealth (OR=1.04 per $10000; 95% CI=1.02, 1.06) but decreased with local hospital bed availability (OR=0.96 per 1000 beds; 95% CI=0.95, 0.97). The likelihood of home death is associated with local rates of home births, suggesting the influence of health care use preferences.

County-level patterns in mortality rates by cause have not been systematically described but are potentially useful for public health officials, clinicians, and researchers seeking to improve health and reduce geographic disparities. To demonstrate the use of a novel method for county-level estimation and to estimate annual mortality rates by US county for 21 mutually exclusive causes of death from 1980 through 2014. Redistribution methods for garbage codes (implausible or insufficiently specific cause of death codes) and small area estimation methods (statistical methods for estimating rates in small subpopulations) were applied to death registration data from the National Vital Statistics System to estimate annual county-level mortality rates for 21 causes of death. These estimates were raked (scaled along multiple dimensions) to ensure consistency between causes and with existing national-level estimates. Geographic patterns in the age-standardized mortality rates in 2014 and in the change in the age-standardized mortality rates between 1980 and 2014 for the 10 highest-burden causes were determined. County of residence. Cause-specific age-standardized mortality rates. A total of 80 412 524 deaths were recorded from January 1, 1980, through December 31, 2014, in the United States. Of these, 19.4 million deaths were assigned garbage codes. Mortality rates were analyzed for 3110 counties or groups of counties. Large between-county disparities were evident for every cause, with the gap in age-standardized mortality rates between counties in the 90th and 10th percentiles varying from 14.0 deaths per 100 000 population (cirrhosis and chronic liver diseases) to 147.0 deaths per 100 000 population (cardiovascular diseases). Geographic regions with elevated mortality rates differed among causes: for example, cardiovascular disease mortality tended to be highest along the southern half of the Mississippi River, while mortality rates from self-harm and

Previous studies reported that declines in age-specific lung cancer death rates among women in the United States abruptly slowed in women younger than age 50 years (ie, women born after the 1950s). However, in view of substantial geographic differences in antitobacco measures and sociodemographic factors that affect smoking prevalence, it is unknown whether this change in the trend was similar across all states. We examined female age-specific lung cancer death rates (1973 through 2007) by year of death and birth in each state by using age-period-cohort models. Cohort relative risks adjusted for age and period effects were used to compare the lung cancer death rate for a given birth cohort to a referent birth cohort (ie, the 1933 cohort herein). Age-specific lung cancer death rates declined continuously in white women in California, but the rates declined less quickly or even increased in the remaining states among women younger than age 50 years and women born after the 1950s, especially in several southern and midwestern states. For example, in some southern states (eg, Alabama), lung cancer death rates among women born in the 1960s were approximately double those of women born in the 1930s. The unfavorable lung cancer trend in white women born after circa 1950 in southern and midwestern states underscores the need for additional interventions to promote smoking cessation in these high-risk populations, which could lead to more favorable future mortality trends for lung cancer and other smoking-related diseases.

Psoriasis is a common chronic disease, mediated by type 1 and 17 helper T cell-driven inflammation. Epidemiological studies have demonstrated a wide range of comorbidities and increased mortality rates. However, the current evidence on psoriasis-related mortality is limited and nationwide data have not been presented previously. In a nationwide population-based cohort we evaluated all-cause and cause-specific death rates in patients with psoriasis as compared to the general population. The entire Danish population aged 18 and above, corresponding to a total of 5,458,627 individuals (50.7% female, 40.9 years ± 19.7), including 94,069 with mild psoriasis (53% female, 42.0 ± 17.0 years) and 28,253 with severe psoriasis (53.4% female, 43.0 ± 16.5 years), was included. A total of 884,661 deaths were recorded, including 10 916 in patients with mild psoriasis and 3699 in patients with severe psoriasis. The age at time of death varied by psoriasis status, i.e. 76.5 ± 14.0, 74.4 ± 12.8 and 72.0 ± 13.4 years, for the general population, mild psoriasis and severe psoriasis respectively. In general, the highest death rates were observed in patients with severe psoriasis. Overall death rates per 1000 patient years were 13.8 [confidence interval (CI) 13.8-13.8], 17.0 (CI 16.7-17.3) and 25.4 (CI 24.6-26.3) for the general population, patients with mild psoriasis and patients with severe psoriasis respectively. This nationwide population-based study of cause-specific death rates in patients with psoriasis demonstrated reduced lifespan and increased rates of all examined specific causes of death in patients with psoriasis compared to the general population. © 2014 European Academy of Dermatology and Venereology.

Objective To evaluate the incidence of death or neurodevelopmental impairment (NDI) at 18 to 22 months corrected age in subjects enrolled in a trial of early dexamethasone treatment to prevent death or chronic lung disease in extremely low birth weight infants. Methods Evaluation of infants at 18 to 22 months corrected age included anthropomorphic measurements, a standard neurological examination, and the Bayley Scales of Infant Development-II, including the Mental Developmental Index (MDI) and the Psychomotor Developmental Index (PDI). NDI was defined as moderate or severe cerebral palsy, MDI or PDI less than 70, blindness, or hearing impairment. Results Death or NDI at 18 to 22 months corrected age was similar in the dexamethasone and placebo groups (65 vs 66 percent, p= 0.99 among those with known outcome). The proportion of survivors with NDI was also similar, as were mean values for weight, length, and head circumference and the proportion of infants with poor growth (50 vs 41 percent, p=0.42 for weight less than 10th percentile). Forty nine percent of infants in the placebo group received treatment with corticosteroid compared to 32% in the dexamethasone group (p=0.02). Conclusion The risk of death or NDI and rate of poor growth were high but similar in the dexamethasone and placebo groups. The lack of a discernible effect of early dexamethasone on neurodevelopmental outcome may be due to frequent clinical corticosteroid use in the placebo group. PMID:23992673

Purpose We tested the hypotheses that CHEK2*1100delC heterozygosity is associated with increased risk of early death, breast cancer–specific death, and risk of a second breast cancer in women with a first breast cancer. Patients and Methods From 22 studies participating in the Breast Cancer Association Consortium, 25,571 white women with invasive breast cancer were genotyped for CHEK2*1100delC and observed for up to 20 years (median, 6.6 years). We examined risk of early death and breast cancer–specific death by estrogen receptor status and risk of a second breast cancer after a first breast cancer in prospective studies. Results CHEK2*1100delC heterozygosity was found in 459 patients (1.8%). In women with estrogen receptor–positive breast cancer, multifactorially adjusted hazard ratios for heterozygotes versus noncarriers were 1.43 (95% CI, 1.12 to 1.82; log-rank P = .004) for early death and 1.63 (95% CI, 1.24 to 2.15; log-rank P < .001) for breast cancer–specific death. In all women, hazard ratio for a second breast cancer was 2.77 (95% CI, 2.00 to 3.83; log-rank P < .001) increasing to 3.52 (95% CI, 2.35 to 5.27; log-rank P < .001) in women with estrogen receptor–positive first breast cancer only. Conclusion Among women with estrogen receptor–positive breast cancer, CHEK2*1100delC heterozygosity was associated with a 1.4-fold risk of early death, a 1.6-fold risk of breast cancer–specific death, and a 3.5-fold risk of a second breast cancer. This is one of the few examples of a genetic factor that influences long-term prognosis being documented in an extensive series of women with breast cancer. PMID:23109706

To characterize the leading causes of death for the urban American Indian/Alaska Native (AI/AN) population and compare with urban White and rural AI/AN populations. We linked Indian Health Service patient registration records with the National Death Index to reduce racial misclassification in death certificate data. We calculated age-adjusted urban AI/AN death rates for the period 1999-2009 and compared those with corresponding urban White and rural AI/AN death rates. The top-5 leading causes of death among urban AI/AN persons were heart disease, cancer, unintentional injury, diabetes, and chronic liver disease and cirrhosis. Compared with urban White persons, urban AI/AN persons experienced significantly higher death rates for all top-5 leading causes. The largest disparities were for diabetes and chronic liver disease and cirrhosis. In general, urban and rural AI/AN persons had the same leading causes of death, although urban AI/AN persons had lower death rates for most conditions. Urban AI/AN persons experience significant disparities in death rates compared with their White counterparts. Public health and clinical interventions should target urban AI/AN persons to address behaviors and conditions contributing to health disparities.

Life Expectancy Can Explain the Precocity-Longevity Hypothesis Association of Early Career Success and Early Death.

PubMed

McCann, Stewart J H

2015-01-01

The precocity-longevity hypothesis that those who reach career milestones earlier in life have shorter life spans was tested with the 430 men elected to serve in the House of Representatives for the 71st U.S. Congress in 1929-1930 who were alive throughout 1930. There was no tendency for those first serving at an earlier age to die sooner or those serving first at a later age to die later than expected based on individual life expectancy in 1930. Although age at first serving was correlated with death age, the correlation was not significant when expected death age was controlled. The results cast serious doubt on the contention of the precocity-longevity hypothesis that the developmental aspects of the prerequisites, concomitants, and consequences of early career achievement peaks actively enhance the conditions for an earlier death.

Measurement of generation-dependent proliferation rates and death rates during mouse erythroid progenitor cell differentiation.

Herein, we describe an experimental and computational approach to perform quantitative carboxyfluorescein diacetate succinimidyl ester (CFSE) cell-division tracking in cultures of primary colony-forming unit-erythroid (CFU-E) cells, a hematopoietic progenitor cell type, which is an important target for the treatment of blood disorders and for the manufacture of red blood cells. CFSE labeling of CFU-Es isolated from mouse fetal livers was performed to examine the effects of stem cell factor (SCF) and erythropoietin (EPO) in culture. We used a dynamic model of proliferation based on the Smith-Martin representation of the cell cycle to extract proliferation rates and death rates from CFSE time-series. However, we found that to accurately represent the cell population dynamics in differentiation cultures of CFU-Es, it was necessary to develop a model with generation-specific rate parameters. The generation-specific rates of proliferation and death were extracted for six generations (G(0) -G(5) ) and they revealed that, although SCF alone or EPO alone supported similar total cell outputs in culture, stimulation with EPO resulted in significantly higher proliferation rates from G(2) to G(5) and higher death rates in G(2) , G(3) , and G(5) compared with SCF. In addition, proliferation rates tended to increase from G(1) to G(5) in cultures supplemented with EPO and EPO + SCF, while they remained lower and more constant across generations with SCF. The results are consistent with the notion that SCF promotes CFU-E self-renewal while EPO promotes CFU-E differentiation in culture.

To examine international rates of preterm birth and potential associations with stillbirths and neonatal deaths at late preterm and term gestation. Ecological study. Canada, USA and 26 countries in Europe. All deliveries in 2004. Information on preterm birth (<37, 32-36, 28-31 and 24-27 weeks of gestation) and perinatal deaths was obtained for 28 countries. Data sources included files and publications from Statistics Canada, the EURO-PERISTAT project and the National Center for Health Statistics. Pearson correlation coefficients and random-intercept Poisson regression were used to examine the association between preterm birth rates and gestational age-specific stillbirth and neonatal death rates. Rate ratios with 95% confidence intervals were estimated after adjustment for maternal age, parity and multiple births. Stillbirths and neonatal deaths ≥ 32 and ≥ 37 weeks of gestation. International rates of preterm birth (<37 weeks) ranged between 5.3 and 11.4 per 100 live births. Preterm birth rates at 32-36 weeks were inversely associated with stillbirths at ≥ 32 weeks (adjusted rate ratio 0.94, 95% CI 0.92-0.96) and ≥ 37 weeks (adjusted rate ratio 0.88, 95% CI 0.85-0.91) of gestation and inversely associated with neonatal deaths at ≥ 32 weeks (adjusted rate ratio 0.88, 95% CI 0.85-0.91) and ≥ 37 weeks (adjusted rate ratio 0.82, 95% CI 0.78-0.86) of gestation. Countries with high rates of preterm birth at 32-36 weeks of gestation have lower stillbirth and neonatal death rates at and beyond 32 weeks of gestation. Contemporary rates of preterm birth are indicators of both perinatal health and obstetric care services. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

A not so happy day after all: excess death rates on birthdays in the U.S.

Peña, Pablo A

2015-02-01

This study estimates average excess death rates on and around birthdays, and explores differences between birthdays falling on weekends and birthdays falling on weekdays. Using records from the U.S. Social Security Administration for 25 million people who died during the period from 1998 to 2011, average excess death rates are estimated controlling for seasonality of births and deaths. The average excess death rate on birthdays is 6.7% (p < 0.0001). No evidence is found of dips in average excess death rates in a ±10 day neighborhood around birthdays that could offset the spikes on birthdays. Significant differences are found between age groups and between weekend and weekday birthdays. Younger people have greater average excess death rates on birthdays, reaching up to 25.4% (p < 0.0001) for ages 20-29. Younger people also show the largest differences between average excess death rates on weekend birthdays and weekday birthdays, reaching up to 64.5 percentage points (p = 0.0063) for ages 1-9. Over the 13-year period analyzed, the estimated excess deaths on birthdays are 4590. Copyright © 2014 Elsevier Ltd. All rights reserved.

How have changes in front air bag designs affected frontal crash death rates? An update.

PubMed

Teoh, Eric R

2014-01-01

Provide updated death rates comparing latest generations of frontal air bags in fatal crashes. Rates of driver and right-front passenger deaths in frontal crashes per 10 million registered vehicle years were compared using Poisson marginal structural models for passenger vehicles equipped with air bags certified as advanced and compliant (CAC), sled-certified air bags with advanced features, and sled-certified air bags without any advanced features. Analyses of driver death rates were disaggregated by age group, gender, and belt use. CAC air bags were associated with slightly elevated frontal crash death rates for both drivers and right-front passengers compared to sled-certified air bags with advanced features, but the differences were not statistically significant. Sled-certified air bags with advanced features were associated with significant benefits for drivers and for right-front passengers compared to sled-certified air bags without advanced features. CAC air bags were associated with a significant increase in belted driver death rate and a comparable but nonsignificant decrease in unbelted driver death rate compared to sled-certified air bags with advanced features. Sled-certified air bags with advanced features were associated with a nonsignificant 2 percent increase in belted driver death rate and a significant 26 percent decrease in unbelted driver death rate, relative to sled-certified air bags without advanced features. Implementing advanced features in sled-certified air bags was beneficial overall to drivers and right-front passengers with sled-certified air bags. No overall benefit was observed for CAC air bags compared to sled-certified air bags with advanced features. Further study is needed to understand the apparent reduction in belted driver protection observed for CAC air bags.

To (1) assess trends in the number and mortality rates of methamphetamine-related death in Australia, 2009-15; (2) assess the characteristics and the cause, manner and circumstances of death; and (3) assess the blood methamphetamine concentrations and the presence of other drugs in methamphetamine-related death. Analysis of cases of methamphetamine-related death retrieved from the National Coronial Information System (NCIS). Australia. All cases in which methamphetamine was coded in the NCIS database as a mechanism contributing to death (n = 1649). Information was collected on cause and manner of death, demographics, location, circumstances of death and toxicology. The mean age of cases was 36.9 years, and 78.4% were male. The crude mortality rate was 1.03 per 100 000. The rate increased significantly over time (P < 0.001), and at 2015 the mortality rate was 1.8 [confidence interval (CI) = 1.2-2.4] times that of 2009. Deaths were due to accidental drug toxicity (43.2%), natural disease (22.3%), suicide (18.2%), other accident (14.9%) and homicide (1.5%). In 40.8% of cases, death occurred outside the major capital cities. The median blood methamphetamine concentration was 0.17 mg/l, and cases in which only methamphetamine was detected had higher concentrations than other cases (0.30 versus 0.15 mg/l, P < 0.001). The median blood methamphetamine concentration varied within a narrow range (0.15-0.20 mg/l) across manner of death. In the majority (82.8%) of cases, substances other than methamphetamine were detected, most frequently opioids (43.1%) and hypnosedatives (38.0%). Methamphetamine death rates doubled in Australia from 2009 to 2015. While toxicity was the most frequent cause, natural disease, suicide and accident comprised more than half of deaths. © 2017 Society for the Study of Addiction.

China is one of the countries with the highest prevalence of diabetes in the world. We analysed all the death certificates mentioning diabetes from 2002 to 2012 in Songjiang District of Shanghai to estimate morality rates and examine cause of death patterns. Mortality data of 2654 diabetics were collected from the database of local CDC. The data set comprises all causes of death, contributing causes and the underlying cause, thereby the mortality rates of diabetes and its specified complications were analysed. The leading underlying causes of death were various cardiovascular diseases (CVD), which collectively accounted for about 30% of the collected death certificates. Diabetes was determined as the underlying cause of death on 28.7%. The trends in mortality showed that the diabetes related death rate increased about 1.78 fold in the total population during the 11-year period, and the death rate of diabetes and CVD comorbidity increased 2.66 fold. In all the diabetes related deaths, the proportion of people dying of ischaemic heart disease or cerebrovascular disease increased from 18.0% in 2002 to 30.5% in 2012. But the proportions attributed directly to diabetes showed a downtrend, from 46.7-22.0%. The increasing diabetes related mortality could be chiefly due to the expanding prevalence of CVD, but has nothing to do with diabetes as the underlying cause. Policy makers should pay more attention to primary prevention of diabetes and on the prevention of cardiovascular complications to reduce the burden of diabetes on survival.

Earlier Initiation and Use of a Greater Number of Iron-Folic Acid Supplements during Pregnancy Prevents Early Neonatal Deaths in Nepal and Pakistan

PubMed Central

Nisar, Yasir Bin; Dibley, Michael J.

2014-01-01

Introduction Early neonatal deaths account for 75% of neonatal deaths globally. Antenatal iron-folic acid (IFA) supplementation has significantly reduced the risk of early neonatal deaths in China and Indonesia. We investigated the impact of antenatal IFA supplements on the risk of early neonatal deaths in Nepal and Pakistan during the last decade. Methods Data from the most recent singleton live-births of 8,186 from two Nepal Demographic and Health Surveys (DHS) and 13,034 from two Pakistan DHS were selected for the current study. The primary outcome was early neonatal deaths and the main study variable was antenatal IFA supplementation. Analyses used multivariate Cox proportional regression, adjusted for the cluster sampling design and for 18 potential confounders. Findings The adjusted risk of early neonatal deaths was significantly reduced by 51% (aHR = 0.49, 95% CI = 0.32–0.75) in Nepal and 23% (aHR = 0.77, 95% CI = 0.59–0.99) in Pakistan with any use of IFA compared to none. When IFA supplementation started at or before the 5th month of pregnancy, the adjusted risk of early neonatal mortality was significantly reduced by 53% in Nepal, and 28% in Pakistan, compared to no IFA. When >90 IFA supplements were used and started at or before 5th months, the adjusted risk of early neonatal deaths was significantly reduced by 57% in Nepal, and 45% in Pakistan. In Nepal 4,600 and in Pakistan 75,000 early neonatal deaths could be prevented annually if all pregnant women used >90 IFA supplements and started at or before the 5th month of pregnancy. Conclusions Any use of IFA supplements was significantly associated with reduced risk of early neonatal deaths in Nepal and Pakistan. The greatest mortality sparing effect of IFA on early neonatal deaths in both countries was with early initiation and use of a greater number of supplements. PMID:25398011

To investigate regional variation in the registration of preterm births <24 weeks of gestation and the impact on infant death rates for English Primary Care Trusts (PCTs). Cohort study. England. All registered births (1 January 2005-31 December 2008) by gestational age and PCT (147 trusts) linked to infant deaths (up to 1 year of life). Late-fetal deaths at 22 and 23 weeks gestation (1 January 2005-31 December 2006). Extremely preterm (<24 weeks) birth rate per 1000 live births and percentage of births registered as live born by PCT. Infant death rate and rank of mortality for (1) all live births and (2) live births over 24 weeks gestation by PCT. Wide between-PCT variation existed in extremely preterm birth (<24 weeks) rates (per 1000 births) (90% central range (0.31, 1.91)) and percentages of births <24 weeks of gestation registered as live born (median 52.6%, 90% central range (26.3%, 79.5%)). Consequently, the percentage of infant deaths arising from these births varied (90% central range (6.7%, 31.9%)). Excluding births <24 weeks, led to significant changes in infant mortality rankings of PCTs, with a median worsening of 12 places for PCTs with low rates of live born preterm births <24 weeks of gestation compared with a median improvement of four ranks for those with higher live birth registration rates. Infant death rates in PCTs in England are influenced by variation in the registration of births where viability is uncertain. It is vital that this variation is minimised before infant mortality is used as indicator for monitoring health and performance and targeting interventions.

To present how the adjustment of incompleteness and misclassification of causes of death in the vital registration (VR) system can contribute to more accurate estimates of the risk of mortality from leading causes of death in northeastern Brazil. After estimating the total numbers of deaths by age and sex in Brazil's Northeast region in 2002-2004 by correcting for undercount in the VR data, adjustment algorithms were applied to the reported cause-of-death structure. Average annual age-standardized mortality rates were computed by cause, with and without the corrections, and compared to death rates for Brazil's South region after adjustments for potential misdiagnosis. Death rates from ischemic heart disease, lower respiratory infections, chronic obstructive pulmonary disease, and perinatal conditions were more than 100% higher for both sexes than what was suggested by the routine VR data. Corrected cause-specific mortality rates were higher in the Northeast region versus the South region for the majority of causes of death, including several noncommunicable conditions. Failure to adjust VR data for undercount of cases reported and misdiagnoses will cause underestimation of mortality risks for the populations of the Northeast region, which are more vulnerable than those in other regions of the country. In order to more reliably understand the pattern of disease, all cause-specific mortality rates in poor populations should be adjusted.

Trends in rates of adolescent suicide and undetermined deaths in Canada from 1981 to 2012 were examined, focusing specifically on variations between Canadian regions. Exploratory hypotheses were formulated for regional variability in adolescent suicide rates over time in Canada. A descriptive time trend analysis using public domain vital statistics data was performed. All deaths from 1981 to 2012 among 15 to 19 year olds coded as suicides or undetermined intent according to the International Classification of Diseases, 9 th and 10 th Revisions were included. While there was an overall stability in adolescent suicide and undetermined death rates across Canada, regional analyses showed that Quebec experienced a 7.6% annual reduction between 2001 and 2012 while the Prairies and Atlantic provinces experienced significant annual increases since 2001. Ontario and British Columbia have had non-significant fluctuations since 2001. The trends remained similar overall when excluding undetermined deaths from the analyses. Variations in adolescent suicide trends across provinces were found. Factors such as provincial suicide action and prevention legislation contributing to these variations remain to be studied, but these regional differences point towards the need for better consistency of suicide prevention strategies across the country.

The present study explored both socioeconomic and climatic factors to obtain a more comprehensive view of the asymmetric regional suicide death rate during 1998-2006 in Taiwan. The annual suicide death rate, population and meteorological data from 19 cities/counties in Taiwan were analysed by multiple regression. Five socioeconomic (sex ratio, no spouse, aged, unemployment and low income) and three climatic (temperature, rainfall and sunshine) factors were identified as significant, explaining 59.0% of the variance in the total suicide death rate. 'Without spouse' and 'aged' were associated with the highest risk, while 'low income with financial aids' was strongly protective. The most influential climatic factor was 'temperature,' which was negatively correlated with suicide. 'Sunshine' was positively associated with suicide. The socioeconomic and climatic factors contributed 52.7% and 6.8%, respectively, to the variance of the total suicide death rate. Limitations of the study included the fact that no individual events were considered, the study was of relatively short duration and it was confined to the territory of Taiwan. Socioeconomic factors outweighed climatic factors in explaining regional differences in the suicide death rate in Taiwan. Temperature weighed more than sunshine. 'Thermotherapy' seems more clinically relevant than the popular light therapy, at least in Taiwan. Copyright © 2008 Elsevier Ltd. All rights reserved.

Drug poisoning mortality has increased substantially in the U.S. over the past 3 decades. Previous studies have described state-level variation and urban-rural differences in drug-poisoning deaths, but variation at the county level has largely not been explored in part because crude county-level death rates are often highly unstable. The goal of the study was to use small-area estimation techniques to produce stable county-level estimates of age-adjusted death rates (AADR) associated with drug poisoning for the U.S., 1999-2009, in order to examine geographic and temporal variation. Population-based observational study using data on 304,087 drug-poisoning deaths in the U.S. from the 1999-2009 National Vital Statistics Multiple Cause of Death Files (analyzed in 2012). Because of the zero-inflated and right-skewed distribution of drug-poisoning death rates, a two-stage modeling procedure was used in which the first stage modeled the probability of observing a death for a given county and year, and the second stage modeled the log-transformed drug-poisoning death rate given that a death occurred. Empirical Bayes estimates of county-level drug-poisoning death rates were mapped to explore temporal and geographic variation. Only 3% of counties had drug-poisoning AADRs greater than ten per 100,000 per year in 1999-2000, compared to 54% in 2008-2009. Drug-poisoning AADRs grew by 394% in rural areas compared to 279% for large central metropolitan counties, but the highest drug-poisoning AADRs were observed in central metropolitan areas from 1999 to 2009. There was substantial geographic variation in drug-poisoning mortality across the U.S. Published by American Journal of Preventive Medicine on behalf of American Journal of Preventive Medicine.

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.

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.

Objectives. To characterize the leading causes of death for the urban American Indian/Alaska Native (AI/AN) population and compare with urban White and rural AI/AN populations. Methods. We linked Indian Health Service patient registration records with the National Death Index to reduce racial misclassification in death certificate data. We calculated age-adjusted urban AI/AN death rates for the period 1999–2009 and compared those with corresponding urban White and rural AI/AN death rates. Results. The top-5 leading causes of death among urban AI/AN persons were heart disease, cancer, unintentional injury, diabetes, and chronic liver disease and cirrhosis. Compared with urban White persons, urban AI/AN persons experienced significantly higher death rates for all top-5 leading causes. The largest disparities were for diabetes and chronic liver disease and cirrhosis. In general, urban and rural AI/AN persons had the same leading causes of death, although urban AI/AN persons had lower death rates for most conditions. Conclusions. Urban AI/AN persons experience significant disparities in death rates compared with their White counterparts. Public health and clinical interventions should target urban AI/AN persons to address behaviors and conditions contributing to health disparities. PMID:26890168

While empirical evidence suggests that elite athletes have superior lifespan outcomes relative to the general population, less is known regarding their causes of death. The purpose of this study was to critically examine the mortality outcomes of deceased National Basketball Association and American Basketball Association players. Death data were collected from publicly available sources until 11 December 2015, and causes of death were categorized using the International Classification of Diseases, Tenth Revision (ICD). Mortality was measured through: i) cause-specific crude death rates (CDR), ii) estimates of death rates per athlete-year (AY), and iii) binary and multinomial regression analyses. We identified 514 causes of death from 787 deceased players (M = 68.1 y ± 16.0) from 16 different ICD groups, 432 of which were from natural causes. Findings showed similar leading causes of death and CDRs to sex- and race-matched controls, higher death rate differences per AY within time-dependent variables (i.e., birth decade, race, and height), and a higher likelihood of dying below the median age of death for black and taller players, although this was highly confounded by birth decade. More complete knowledge of mortality outcomes would provide broad public health applications and disarm harmful stereotypes of elite athlete health.

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. 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. 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. 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.

Problem/Condition Heart disease is the leading cause of death in the United States. In 2015, heart disease accounted for approximately 630,000 deaths, representing one in four deaths in the United States. Although heart disease death rates decreased 68% for the total population from 1968 to 2015, marked disparities in decreases exist by race and state. Period Covered 1968–2015. Description of System The National Vital Statistics System (NVSS) data on deaths in the United States were abstracted for heart disease using diagnosis codes from the eighth, ninth, and tenth revisions of the International Classification of Diseases (ICD-8, ICD-9, and ICD-10) for 1968–2015. Population estimates were obtained from NVSS files. National and state-specific heart disease death rates for the total population and by race for adults aged ≥35 years were calculated for 1968–2015. National and state-specific black-white heart disease mortality ratios also were calculated. Death rates were age standardized to the 2000 U.S. standard population. Joinpoint regression was used to perform time trend analyses. Results From 1968 to 2015, heart disease death rates decreased for the total U.S. population among adults aged ≥35 years, from 1,034.5 to 327.2 per 100,000 population, respectively, with variations in the magnitude of decreases by race and state. Rates decreased for the total population an average of 2.4% per year, with greater average decreases among whites (2.4% per year) than blacks (2.2% per year). At the national level, heart disease death rates for blacks and whites were similar at the start of the study period (1968) but began to diverge in the late 1970s, when rates for blacks plateaued while rates for whites continued to decrease. Heart disease death rates among blacks remained higher than among whites for the remainder of the study period. Nationwide, the black-white ratio of heart disease death rates increased from 1.04 in 1968 to 1.21 in 2015, with large increases

Objective Trends in rates of adolescent suicide and undetermined deaths in Canada from 1981 to 2012 were examined, focusing specifically on variations between Canadian regions. Exploratory hypotheses were formulated for regional variability in adolescent suicide rates over time in Canada. Methods A descriptive time trend analysis using public domain vital statistics data was performed. All deaths from 1981 to 2012 among 15 to 19 year olds coded as suicides or undetermined intent according to the International Classification of Diseases, 9th and 10th Revisions were included. Results While there was an overall stability in adolescent suicide and undetermined death rates across Canada, regional analyses showed that Quebec experienced a 7.6% annual reduction between 2001 and 2012 while the Prairies and Atlantic provinces experienced significant annual increases since 2001. Ontario and British Columbia have had non-significant fluctuations since 2001. The trends remained similar overall when excluding undetermined deaths from the analyses. Conclusions Variations in adolescent suicide trends across provinces were found. Factors such as provincial suicide action and prevention legislation contributing to these variations remain to be studied, but these regional differences point towards the need for better consistency of suicide prevention strategies across the country.

A review of 452 trauma deaths in Hillsborough County, Florida, in 1984 documented that 23% of non-CNS trauma deaths were preventable and occurred because of inadequate resuscitation or delay in proper surgical care. In late 1988 Hillsborough County organized a County Trauma Agency (HCTA) to coordinate trauma care among prehospital providers and state-designated trauma centers. The purpose of this study was to review county trauma deaths after the inception of the HCTA to determine the frequency of preventable deaths. 504 trauma deaths occurring between October 1989 and April 1991 were reviewed. Through committee review, 10 deaths were deemed preventable; 2 occurred outside the trauma system. Of the 10 deaths, 5 preventable deaths occurred late in severely injured patients. The preventable death rate has decreased to 7.0% with system care. The causes of preventable deaths have changed from delayed or inadequate intervention to postoperative care errors.

BACKGROUND Inmates face challenges upon release from prison, including increased risk of death. We examine mortality among former inmates in North Carolina, including both violent and nonviolent deaths. METHODS A retrospective cohort study among former North Carolina inmates released between 2008 and 2010 were linked with North Carolina mortality data to determine cause of death. Inmates were followed through December 31, 2012. Mortality rates among former inmates were compared with deaths among North Carolina residents using standardized mortality ratios (SMRs). RESULTS Among former inmates (N = 41,495), there were 926 deaths during the study period. Compared to the North Carolina general population, SMRs were higher for all-cause mortality for total deaths (SMR = 2.10, 95% CI: 1.97-2.24), heart disease (SMR = 4.45, 95% CI: 3.64-5.34), cancer (SMR = 3.92, 95% CI: 3.34-4.62), suicide (SMR = 14.46, 95% CI: 10.28-19.76), and homicide (SMR = 7.98, 95% CI: 6.34-10.03). DISCUSSION The death rate among former North Carolina inmates is significantly higher than that of other North Carolina residents. Although more research is needed, identifying areas for interventions is essential for reducing the risk of death among this population. ©2017 by the North Carolina Institute of Medicine and The Duke Endowment.

Rates of obstetric intervention in labor, including cesarean delivery, have increased significantly in most developed countries. It is, however, unclear if this has been paralleled by decreased rates of perinatal and neonatal death associated with complications of labor at term. To determine whether rates of perinatal death at term, either during labor or in the neonatal period, have changed in Scotland during the last 20 years and whether this was associated with a reduction in deaths ascribed to intrapartum anoxia. A population-based, retrospective cohort study of linked data from a registry of births (Scottish Morbidity Record 02) and a registry of perinatal deaths (Scottish Stillbirth and Infant Death Survey) between 1988 and 2007. Participants included all births of a singleton infant in a cephalic presentation at term (N = 1,012,266), excluding those with perinatal death due to congenital anomaly or antepartum stillbirth. Delivery-related perinatal death, defined as intrapartum stillbirth or neonatal death unrelated to congenital abnormality. These events were also subdivided into those events ascribed to intrapartum anoxia and all other causes. The risk of death was modeled using logistic regression and analyses were adjusted for maternal age, height, parity, socioeconomic deprivation status, gestational age, birth weight percentile, fetal sex, onset of labor, and the annual number of births per hospital. During the study period, the risk of delivery-related perinatal death decreased from 8.8 to 5.5 per 10,000 births (unadjusted change, -38%; 95% confidence interval [CI], -51% to -21%). When analyzed by the cause of death, there was a significant decrease in the risk of death ascribed to intrapartum anoxia (5.7 to 3.0 per 10,000 births; unadjusted change, -48%; 95% CI, -62% to -29%), but no significant change in the risk of death ascribed to other causes. When deaths ascribed to intrapartum anoxia were analyzed by the time of death in relation to delivery

US-funded measurements of cervical cancer death rates in India: scientific and ethical concerns.

PubMed

Suba, Eric J

2014-01-01

Since 1998, randomised trials in India funded by the US National Cancer Institute (NCI) and the Bill and Melinda Gates Foundation have compared cervical cancer death rates among 224,929 women offered cervical screening to those among 138,624 women offered no screening whatsoever. To date, at least 254 women in unscreened control groups have died of cervical cancer. The United States Office for Human Research Protections (OHRP) determined that the subjects in the studies were not given adequate information for the purpose of providing informed consent. The determinations of the OHRP contradict assurances given by other American medical and bioethical leaders. CONCERNS: Defective scientific design required inadequate informed consent. US-funded measurements of death rates may have needlessly delayed development of indispensable, life-saving public health infrastructure. US-funded measurements of incidence and death rates proved to be scientifically irreproducible and unreliable. Predictably, nothing was learned from these measurements that was not already known. Statistical bias embedded in measurement of death rates yielded the absurd conclusion that Papanicolaou screening does not prevent cervical cancer, leading to a marketing campaign for a proprietary human papillomavirus (HPV) screening test unaffordable for the women among whom death rates had been measured. Inexplicably, measurements of death rates among unscreened women were continued even after the mortality benefit of screening had been confirmed. Quality management of NCI fundedvisual screening (VIA) in Mumbai failed catastrophically, with unsettling implications for VIA conducted by those with less expertise. High-quality screening must be provided to all surviving unscreened women without further delay. US-based global health organisations should institutionalise a commitment to “improving health outcomes as rapidly as possible among as many people as possible.” Those who suffered avoidable harm and

The 90-day risk of cerebral infarction in patients with transient ischaemic attack (TIA) is estimated at between 8% and 20%. There is little consensus as to which diagnostic strategy is most effective. This study evaluates the benefits of early transthoracic echocardiography (TTE) with carotid and transcranial Doppler ultrasound in patients with TIA. Prospective study of patients with TIA in an emergency department setting. Demographic data, vascular risk factors, and ABCD(2) score were analysed. TIA aetiology was classified according to TOAST criteria. All patients underwent early vascular studies (<72hours), including TTE, carotid ultrasound, and transcranial Doppler. Primary endpoints were recurrence of stroke or TIA, myocardial infarction (MI), or vascular death during the first year. We evaluated 92 patients enrolled over 24 months. Mean age was 68.3±13 years and 61% were male. The mean ABCD(2) score was 3 points (≥5 in 30%). The distribution of TIA subtypes was as follows: 12% large-artery atherosclerosis; 30% cardioembolism; 10% small-vessel occlusion; 40% undetermined cause; and 8% rare causes. Findings from the early TTE led to a change in treatment strategy in 6 patients (6.5%) who displayed normal physical examination and ECG findings. At one year of follow-up, 3 patients had experienced stroke (3.2%) and 1 patient experienced MI (1%); no vascular deaths were identified. In our TIA patients, early vascular study and detecting patients with silent cardiomyopathy may have contributed to the low rate of vascular disease recurrence.

IIHS side crash test ratings and occupant death risk in real-world crashes.

PubMed

Teoh, Eric R; Lund, Adrian K

2011-10-01

To evaluate how well the Insurance Institute for Highway Safety (IIHS) side crash test ratings predict real-world occupant death risk in side-impact crashes. The IIHS has been evaluating passenger vehicle side crashworthiness since 2003. In the IIHS side crash test, a vehicle is impacted perpendicularly on the driver's side by a moving deformable barrier simulating a typical sport utility vehicle (SUV) or pickup. Injury ratings are computed for the head/neck, torso, and pelvis/leg, and vehicles are rated based on their ability to protect occupants' heads and resist occupant compartment intrusion. Component ratings are combined into an overall rating of good, acceptable, marginal, or poor. A driver-only rating was recalculated by omitting rear passenger dummy data. Data were extracted from the Fatality Analysis Reporting System (FARS) and National Automotive Sampling System/General Estimates System (NASS/GES) for the years 2000-2009. Analyses were restricted to vehicles with driver side air bags with head and torso protection as standard features. The risk of driver death was computed as the number of drivers killed (FARS) divided by the number involved (NASS/GES) in left-side impacts and was modeled using logistic regression to control for the effects of driver age and gender and vehicle type and curb weight. Death rates per million registered vehicle years were computed for all outboard occupants and compared by overall rating. Based on the driver-only rating, drivers of vehicles rated good were 70 percent less likely to die when involved in left-side crashes than drivers of vehicles rated poor, after controlling for driver and vehicle factors. Compared with vehicles rated poor, driver death risk was 64 percent lower for vehicles rated acceptable and 49 percent lower for vehicles rated marginal. All 3 results were statistically significant. Among components, vehicle structure rating exhibited the strongest relationship with driver death risk. The vehicle

Oxygen Uptake Efficiency Plateau Best Predicts Early Death in Heart Failure

PubMed Central

Hansen, James E.; Stringer, William W.

2012-01-01

Background: The responses of oxygen uptake efficiency (ie, oxygen uptake/ventilation = V˙o2/V˙e) and its highest plateau (OUEP) during incremental cardiopulmonary exercise testing (CPET) in patients with chronic left heart failure (HF) have not been previously reported. We planned to test the hypothesis that OUEP during CPET is the best single predictor of early death in HF. Methods: We evaluated OUEP, slope of V˙o2 to log(V˙e) (oxygen uptake efficiency slope), oscillatory breathing, and all usual resting and CPET measurements in 508 patients with low-ejection-fraction (< 35%) HF. Each had further evaluations at other sites, including cardiac catheterization. Outcomes were 6-month all-reason mortality and morbidity (death or > 24 h cardiac hospitalization). Statistical analyses included area under curve of receiver operating characteristics, ORs, univariate and multivariate Cox regression, and Kaplan-Meier plots. Results: OUEP, which requires only moderate exercise, was often reduced in patients with HF. A low % predicted OUEP was the single best predictor of mortality (P < .0001), with an OR of 13.0 (P < .001). When combined with oscillatory breathing, the OR increased to 56.3, superior to all other resting or exercise parameters or combinations of parameters. Other statistical analyses and morbidity analysis confirmed those findings. Conclusions: OUEP is often reduced in patients with HF. Low % predicted OUEP (< 65% predicted) is the single best predictor of early death, better than any other CPET or other cardiovascular measurement. Paired with oscillatory breathing, it is even more powerful. PMID:22030802

Death rates 1996-2001, Carstairs' 2001 deprivation score and indicators, population density, black and minority ethnic group (BME) and population change 1971-2001 were calculated for 641 parliamentary constituencies in Britain. Constituencies were grouped into Carstairs' deciles. We assessed standard errors of all variables by decile and the relationship between death rates and socio-demographic variables with Pearson's correlations and linear regression by decile and for all constituencies combined. Standard errors in death rates and most socio-demographic variables were greatest for the most deprived decile. Death rates among all constituencies were positively correlated with Carstairs' score and indicators, density and BME, but for the most deprived decile, there was no association with Carstairs and a negative correlation with overcrowding, density and BME. For the most deprived decile multivariate models containing population density, BME and change had substantially higher R(2). Understanding variations in death rates between deprived areas requires greater consideration of their socio-demographic diversity including their population density, ethnicity and migration.

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

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.

Estimating division and death rates from CFSE data

de Boer, Rob J.; Perelson, Alan S.

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

During the past decade an increasing number of countries have adopted policies that emphasize donation after cardiocirculatory death (DCD) in an attempt to address the widening gap between the demand for transplantable organs and the availability of organs from donation after brain death (DBD) donors. In order to examine how these policy shifts have affected overall deceased organ donor (DD) and DBD rates, we analyzed deceased donation rates from 82 countries from 2000–2010. On average, overall DD, DBD and DCD rates have increased over time, with the proportion of DCD increasing 0.3% per year (p = 0.01). Countries with higher DCD rates have, on average, lower DBD rates. For every one-per million population (pmp) increase in the DCD rate, the average DBD rate decreased by 1.02 pmp (95% CI: 0.73, 1.32; p<0.0001). We also found that the number of organs transplanted per donor was significantly lower in DCD when compared to DBD donors with 1.51 less transplants per DCD compared to DBD (95% CI: 1.23, 1.79; p<0.001). Whilst the results do not infer a causal relationship between increased DCD and decreased DBD rates, the significant correlation between higher DCD and lower DBD rates coupled with the reduced number of organs transplanted per DCD donor suggests that a national policy focus on DCD may lead to an overall reduction in the number of transplants performed.

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.

Graft dysfunction after liver transplantation is a serious complication that can lead to graft loss and patient death. This was a study to identify risk factors for early death (up to 30 days after transplantation). It was an observational and retrospective analysis at the Liver Transplantation Unit, Hospital de Clinicas, State University of Campinas, Brazil. From July 1994 to December 2012, 302 patients were included (>18 years old, piggyback technique). Of these cases, 26% died within 30 days. For analysis, Student t tests and chi-square were used to analyze receptor-related (age, body mass index, serum sodium, graft dysfunction, Model for End-Stage Liver Disease score, renal function, and early graft dysfunction [EGD type 1, 2, or 3]), surgery (hot and cold ischemia, surgical time, and units of packed erythrocytes [pRBC]), and donor (age, hypotension, and brain death cause) factors. Risk factors were identified by means of logistic regression model adjusted by the Hosmer-Lemeshow test with significance set at P < .05. We found that hyponatremic recipients had a 6.26-fold higher risk for early death. There was a 9% reduced chance of death when the recipient serum sodium increased 1 unit. The chance of EGD3 to have early death was 18-fold higher than for EGD1 and there was a 13% increased risk for death for each unit of pRBC transfused. Donor total bilirubin, hyponatremia, massive transfusion, and EGD3 in the allocation graft should be observed for better results in the postoperative period. Copyright © 2015 Elsevier Inc.

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

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

Comparing rates of sudden unexpected death in infancy (SUDI) in different countries and over time is difficult, as these deaths are certified differently in different countries, and, even within the same jurisdiction, changes in this death certification process have occurred over time. To identify if International Classification of Diseases-10 (ICD-10) codes are being applied differently in different countries, and to develop a more robust tool for international comparison of these types of deaths. Usage of six ICD-10 codes, which code for the majority of SUDI, was compared for the years 2002-2010 in eight high-income countries. There was a great variability in how each country codes SUDI. For example, the proportion of SUDI coded as sudden infant death syndrome (R95) ranged from 32.6% in Japan to 72.5% in Germany. The proportion of deaths coded as accidental suffocation and strangulation in bed (W75) ranged from 1.1% in Germany to 31.7% in New Zealand. Japan was the only country to consistently use the R96 code, with 44.8% of SUDI attributed to that code. The lowest, overall, SUDI rate was seen in the Netherlands (0.19/1000 live births (LB)), and the highest in New Zealand (1.00/1000 LB). SUDI accounted for one-third to half of postneonatal mortality in 2002-2010 for all of the countries except for the Netherlands. The proposed set of ICD-10 codes encompasses the codes used in different countries for most SUDI cases. Use of these codes will allow for better international comparisons and tracking of trends over time. Published by the BMJ Publishing Group Limited.

Demographic trade-offs in a neutral model explain death-rate--abundance-rank relationship.

PubMed

2009-01-01

The neutral theory of biodiversity has been criticized for its neglect of species differences. Yet it is much less heeded that S. P. Hubbell's definition of neutrality allows species to differ in their birth and death rates as long as they have an equal per capita fitness. Using the lottery model of competition we find that fitness equalization through birth-death trade-offs can make species coexist longer than expected for demographically identical species, whereas the probability of monodominance for a species under zero-sum neutral dynamics is equal to its initial relative abundance. Furthermore, if newly arising species in a community survive preferentially they are more likely to slip through the quagmire of rareness, thus creating a strong selective bias favoring their community membership. On the other hand, high-mortality species, once having gained a footing in the community, are more likely to become abundant due to their compensatory high birth rates. This unexpected result explains why a positive association between species abundance and per capita death rate can be seen in tropical-forest communities. An explicit incorporation of interspecific trade-offs between birth and death into the neutral theory increases the theory's realism as well as its predictive power.

Not only in newborns with Down syndrome, but newborns without phenotypic features of Down syndrome also develop transient myeloproliferative disorder (TMD). In these cases, trisomy 21 and related chromosomal abnormalities are either constitutionally mosaic or limited to blood cells. Risk factors for early death of these patients are unknown so far. We here report a fatal case of TMD without phenotypic features of Down syndrome and review literature to identify risk factors associated with early death. Not only are gestational age and white blood cell count risk factors for early death in TMD with Down syndrome, but they also appear to be risk factors in TMD without Down syndrome.

The aim: of the study was to determine the situation of preterm births and early neonatal mortality during 2007-2014 in Tuzla Canton, Bosnia and Herzegovina. Methods: The study covers a 8-year period and is based on the protocols at the Tuzla Clinic for Gynecology and Obstetrics that covers all birth in Tuzla Canton area. We analyzed the gestational age of all newborns and recorded the number of neonatal deaths in the first week after birth. Demographics, pregnancy and birth characteristics were collected from the maternal records. Results: The total number of births in the period was 32738. Preterm birth was identified in 2401 (7.3%) cases with 12,5% occurring before 32 gestational weeks and 64% in 35-36 gestational weeks. The mothers of the 24-31 gws preterm group were significantly younger that those in the 32-36 group. In the 32-36 group there were significantly greater proportions of mothers with assisted reproductive technology and pre-eclampsia and 16.7% was medical induced preterm births versus 11.4 % in the 24-31 PTB group, p<0.05. The incidence of PTB did no vary significantly during the period, the lowest rate was found in 2010 (6.4%). A total of 221 children died giving a early mortality rate of 6.8 per 1000 live born over the 8 years. The majority 156 dying infants (70.6%) were preterm, only 5.7% died being born in the 35-36 gestational week (5.9 per 1000). Overall the preterm early mortality (7.3 per 1000) has shown a decreasing tendency during the latter years. Conclusion: During the last 8 years there have been no significant decline in preterm birth in the Tuzla region while a decline in early neonatal death has been registered. PMID:27047264

To investigate the relationship between baseline heart rate(HR) and all-cause death(ACD)in general population. 93 716 workers with heart rate between 40 bpm/min-120 bpm/min and without histories of stroke were selected from the '2006-2007 health examination records' in Kailuan and completed the electrocardiogram exam. Related information were also gathered. These subjects were followed up from July 2006 to December 2010, with the mean time of follow-up as 47.5±4.3 months. During the follow-up period, the occurrence of all-cause death was observed every half a year. (1)The lowest cumulative mortality rate was 1.61% in the group with 60-69 bpm/min. The lowest cumulative mortality rate was 1.78% in the group of 60-69 bpm/min in men. There was no death events observed in women with less than 50 bpm/min and the lowest cumulative mortality rate was 0.60% in the group of 80-89 bpm/min in women. (2)Data from Cox proportional hazard regression analysis showed that the RR(95%CI)of cumulative mortality rates in general population were 1.187 (1.039-1.336), 1.392(1.185-1.636), 1.733(1.404-2.139)and 2.716 (2.171-3.398)in the groups of 70-79, 80-89, 90-99 and ≥100 bpm/min, respectively. The RRs (95% CI) of cumulative mortality in men were 1.227(1.067-1.410), 1.481(1.254-1.750), 1.754 (1.406-2.188)and 2.831 (2.245-3.571) respectively. In women, when comparing with the group of 80-89 bpm/min, the RRs (95%CI)of all-cause death were 0.671(0.568-0.793), 0.825(0.703-0.970) and 1.925 (1.512-2.453)respectively in the groups of 60-69, 70-79 and ≥100 bpm/min. When HR exceeding ≥70 bpm/min, the increase of HR would also increase the rate of ACD. Results of our study also showed a J-shaped curve relation between HR and mortality.

Socioeconomic status has important associations with disease-specific mortality in the general population. Although individuals with Severe Mental Illnesses (SMI) experience significant premature mortality, the relationship between socioeconomic status and mortality in this group remains under investigated. We aimed to assess the impact of socioeconomic status on rate and cause of death in individuals with SMI (schizophrenia and bipolar disorder) relative to the local (Glasgow) and wider (Scottish) populations. Cause and age of death during 2006-2010 inclusive for individuals with schizophrenia or bipolar disorder registered on the Glasgow Psychosis Clinical Information System (PsyCIS) were obtained by linkage to the Scottish General Register Office (GRO). Rate and cause of death by socioeconomic status, measured by Scottish Index of Multiple Deprivation (SIMD), were compared to the Glasgow and Scottish populations. Death rates were higher in people with SMI across all socioeconomic quintiles compared to the Glasgow and Scottish populations, and persisted when suicide was excluded. Differences were largest in the most deprived quintile (794.6 per 10,000 population vs. 274.7 and 252.4 for Glasgow and Scotland respectively). Cause of death varied by socioeconomic status. For those living in the most deprived quintile, higher drug-related deaths occurred in those with SMI compared to local Glasgow and wider Scottish population rates (12.3% vs. 5.9%, p = <0.001 and 5.1% p = 0.002 respectively). A lower proportion of deaths due to cancer in those with SMI living in the most deprived quintile were also observed, relative to the local Glasgow and wider Scottish populations (12.3% vs. 25.1% p = 0.013 and 26.3% p = <0.001). The proportion of suicides was significantly higher in those with SMI living in the more affluent quintiles relative to Glasgow and Scotland (54.6% vs. 5.8%, p = <0.001 and 5.5%, p = <0.001). Excess mortality in those with SMI occurred across all

To assess the predictive value of gait speed for early death in older outpatients with cancer. Prospective bicentric observational cohort study. The Physical Frailty in Elder Cancer patients (PF-EC) study (France). One hundred and ninety outpatients with cancer during the first 6 months of follow up in the PF-EC study. The association between usual gait speed over 4 m alone (GS) or included in the short physical performance battery (SPPB) and overall survival within 6 months following a comprehensive geriatric assessment (CGA). A Cox proportional-hazard regression model was performed in non-survivors for clinical factors from the CGA, along with c reactive protein (CRP). Two models were created to assess GS alone and from inclusion in the SPPB. The mean age was 80.6 years, and 50.5% of the participants were men. Death occurred in 11% (n=22) of the participants within the 6 month follow up period. Of these participants, 98% had solid cancers, and 33% had a metastatic disease. A GS < 0.8 m/s (HR=5.6, 95%CI=1.6-19.7, p=0.007), a SPPB < 9 (HR=5.8, 95%CI=1.6-20.9, p=0.007) and a CRP of 50 mg/l or greater (p<0.0001) were significantly associated with early death in the two multivariate analyses. Cancer site and extension were not significantly associated with early death. Walking tests are associated with early death within the 6 month follow up period after a CGA independent of cancer site and cancer extension. GS alone < 0.8 m/s is at least as efficacious as the SPPB in predicting this outcome. GS alone could be used routinely as a marker of early death to adapt oncologic therapeutics. Further studies are needed to validate these preliminary data.

Early phase drugs and biologicals clinical trials on worldwide leading causes of death: a descriptive analysis.

Dal-Ré, Rafael

2011-06-01

To describe the global effort targeting the major causes of mortality in terms of "open" early phase clinical trials with drugs and biologicals. Sixteen of the 20 leading causes of death were chosen; 9 of these were also amongst the top 10 causes of death in low-income countries. Studies were identified from the ClinicalTrials.gov database and included phase 1 and/or 2 "interventional" "open" trials, i.e. those recruiting or about to start recruitment. Trials were considered in terms of sponsorship [industry, universities and other organisations (UNO), and US federal agencies (NIH included)], genders and age groups included, and whether they were conducted with drugs and/or biologicals. The search was performed in March 2010. A total of 2,298 (824 phase 1; 1,474 phase 2) trials were retrieved. Of these, 67% were on trachea, bronchus, and lung cancers (25%); diabetes mellitus (15%); colon and rectum cancers (14%); and HIV/AIDS (12%). In contrast, only 4% were trials on diarrhoeal disease, nephrosis and nephritis, liver cirrhosis, and prematurity and low birth weight. UNO were the first source of funding. Fifty-two percent of phase 1 non-cancer trials were on healthy volunteers. Twenty-nine percent of all trials were co-funded. There were 4.6 times as many drug trials as those with biologicals. Only 7% were conducted with a combination of drugs and biologicals, the majority (78%) on cancers. Discrimination in terms of gender or age group was not observed. Four of the 16 diseases considered represented 2/3 of early phase trials. Cancers were a top priority for all sponsors. Increasing attention should be given to conditions with current and projected global high mortality rates that had few "open" early phase trials.

The 15% mortality rate of liver transplant recipients at one yr may be viewed as a feat in comparison with the waiting list mortality, yet it nonetheless leaves room for much improvement. Our aim was to critically examine the mortality rates to identify high-risk periods and to incorporate cause of death into the analysis of post-transplant survival. We performed a retrospective analysis on United Network for Organ Sharing data for all adult recipients of liver transplants from January 1, 2002 to October 31, 2011. Our analysis included multivariate logistic regression where the primary outcome measure was patient death of 49,288 recipients. The highest mortality rate by day post-transplant was on day 0 (0.9%). The most significant risk factors were as follows: for one-d mortality from technical failure, intensive care unit admission odds ratio (OR 3.2); for one-d mortality from graft failure, warm ischemia >75 min (OR 5.6); for one-month mortality from infection, a previous transplant (OR 3.3); and for one-month mortality from graft failure, a previous transplant (OR 3.7). We found that the highest mortality rate after liver transplantation is within the first day and the first month post-transplant. Those two high-risk periods have common, as well as different, risk factors for mortality. © 2013 John Wiley & Sons A/S.

To systematically study the number of U.S. resident deaths from all causes, including suicide. The more than 9,900 programs accredited by the Accreditation Council for Graduate Medical Education (ACGME) annually report the status of residents. The authors aggregated ACGME data on 381,614 residents in training during years 2000 through 2014. Names of residents reported as deceased were submitted to the National Death Index to learn causes of death. Person-year calculations were used to establish resident death rates and compare them with those in the general population. Between 2000 and 2014, 324 individuals (220 men, 104 women) died while in residency. The leading cause of death was neoplastic disease, followed by suicide, accidents, and other diseases. For male residents the leading cause was suicide, and for female residents, malignancies. Resident death rates were lower than in the age- and gender-matched general population. Temporal patterns showed higher rates of death early in residency. Deaths by suicide were higher early in training, and during the first and third quarters of the academic year. There was no upward or downward trend in resident deaths over the 15 years of this study. Neoplastic disease and suicide were the leading causes of death in residents. Data for death by suicide suggest added risk early in residency and during certain months of the academic year. Providing trainees with a supportive environment and with medical and mental health services is integral to reducing preventable deaths and fostering a healthy physician workforce.

Belgium and The Netherlands have fairly similar smoking prevalence patterns, but distinct tobacco control policies. It is our aim to use lung cancer death rates, especially among the youngest age groups (30-39 years), as indicators of past smoking behavioral patterns to evaluate recent tobacco control efforts in both countries. Lung cancer mortality rates from 1954 to 1997 and from 1950 to 2000 were investigated in Belgium and The Netherlands, respectively, using the joinpoint regression modeling technique (log-linear Poisson models) to calculate annual percent change in death rate. In the most recent period (1984-2000) overall male lung cancer death rates have been declining at a faster rate in The Netherlands than in Belgium. In contrast, overall female lung cancer death rates (between 1950 and 2000) have been increasing at a faster rate in The Netherlands than in Belgium. Since 1988, however, APCs in death rates among Dutch females have begun to level off. Interestingly, during this same period, a significant annual decline of 7.7% among the youngest Dutch women (30-39 years) has been observed. Tobacco use prevention and interventions seem to have an impact on smoking prevalence, especially among younger age groups. In The Netherlands, where aggressive anti-tobacco campaigns were introduced a few years earlier than in Belgium, male lung cancer mortality rates have been declining more rapidly, and female lung cancer mortality rates have begun to level off.

Increasing cutaneous melanoma incidence rates in the United States have been attributed to heightened detection of thin (≤ 1-mm) lesions. We sought to describe melanoma incidence and mortality trends in the 12 cancer registries covered by the Surveillance, Epidemiology, and End Results program and to estimate the contribution of thin lesions to melanoma mortality. We used joinpoint analysis of Surveillance, Epidemiology, and End Results incidence and mortality data from 1992 to 2006. During 1992 through 2006, melanoma incidence rates among non-Hispanic whites increased for all ages and tumor thicknesses. Death rates increased for older (>65 years) but not younger persons. Between 1998 to 1999 and 2004 to 2005, melanoma death rates associated with thin lesions increased and accounted for about 30% of the total melanoma deaths. Availability of long-term incidence data for 14% of the US population was a limitation. The continued increases in melanoma death rates for older persons and for thin lesions suggest that the increases may partly reflect increased ultraviolet radiation exposure. The substantial contribution of thin lesions to melanoma mortality underscores the importance of standard wide excision techniques and the need for molecular characterization of the lesions for aggressive forms.

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. 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. 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. Significant associations were observed between decreasing death rates of emphysema, asthma, and pneumonia and decreases in levels of ambient air pollutants in North Carolina.

Medical emergency team (MET) call criteria are late signs of a deteriorating clinical condition. Some early signs predict in-hospital death but have a high prevalence so their use as single sign call criteria could be wasteful of resources. This study searched a large database to explore the association of combinations of recordings of early signs (ES), or early with late signs (LS) with in-hospital death. A cross-sectional survey was undertaken of 3046 non-do not attempt resuscitation adult admissions in 5 hospitals without MET over 14 days. The medical records were reviewed for recordings of 26 ES and 21 LS and in-hospital death. Combinations of ES with or without LS were examined as predictors of death. Global modified early warning scores (GMEWS) were calculated. ES with LS, plus LS only, had higher odd ratios than ES alone. Four combinations of ES were strongly associated with death: cardiovascular plus respiratory with decrease in urinary output, cardiovascular plus respiratory with a decrease in consciousness, respiratory with decrease in urinary output, and cardiovascular plus respiratory. In other combinations, recordings of SpO2 90-95%, systolic blood pressure 80-100 mmHg or decrease in urinary output in turn occurring with one or more disturbed blood gas variable were associated with death. Compared with admissions whose GMEWS were 0-2, admissions with GMEWS 5-15 were 27.1 times more likely to die while those with GMEWS 3-4 were 6.5 times more likely. The results support the inclusion of early signs of a deteriorating clinical condition in sets of call criteria.

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.

Early death (ED) is one of the most critical issues involved in the current care of patients with acute promyelocytic leukemia (APL). Factors identified as independent predictors of ED varied among published studies. We retrospectively analyzed the incidence, causes, and prognostic factors of ED in a series of 216 patients with newly diagnosed APL who received arsenic trioxide (ATO) as induction therapy. Multivariate logistic regression analysis was used to determine the association of clinical factors with overall ED, hemorrhagic ED, death within 7 days, and death within 8-30 days. In total, 35 EDs (16.2%) occurred that were caused by hemorrhage, differentiation syndrome (DS), infection, and other causes, in order of prevalence. The independent prognostic factors for overall ED and death within 8-30 days were the same and included serum creatinine level, Eastern Cooperative Oncology Group (ECOG) score, sex, and fibrinogen level. The risk factors for hemorrhagic ED and death within 7 days were similar and included serum creatinine level, ECOG score, and white blood cell count, while hemorrhagic ED was also associated with D-dimer. Our findings revealed a high rate of ED, and the causes of ED were similar to those among patients who received ATRA-based therapy. Increased creatinine level was the most powerful predictor, and an ECOG score greater than 2 was another strong prognostic factor for all four types of ED.

To compare the mortality in those previously hospitalised for mental disorder in Scotland to that experienced by the general population. Population-based historical cohort study using routinely available psychiatric hospital discharge and death records. All Scotland. Individuals with a first hospital admission for mental disorder between 1986 and 2009 who had died by 31 December 2010 (34 243 individuals). The main outcome measure was death from any cause, 1986-2010. Excess mortality was presented as standardised mortality ratios (SMRs) and years of life lost (YLL). Excess mortality was assessed overall and by age, sex, main psychiatric diagnosis, whether the psychiatric diagnosis was 'complicated' (ie, additional mental or physical ill-health diagnoses present), cause of death and time period of first admission. 111 504 people were included in the study, and 34 243 had died by 31 December 2010. The average reduction in life expectancy for the whole cohort was 17 years, with eating disorders (39-year reduction) and 'complicated' personality disorders (27.5-year reduction) being worst affected. 'Natural' causes of death such as cardiovascular disease showed modestly elevated relative risk (SMR1.7), but accounted for 67% of all deaths and 54% of the total burden of YLL. Non-natural deaths such as suicide showed higher relative risk (SMR5.2) and tended to occur at a younger age, but were less common overall (11% of all deaths and 22% of all YLL). Having a 'complicated' diagnosis tended to elevate the risk of early death. No worsening of the overall excess mortality experienced by individuals with previous psychiatric admission over time was observed. Early death for those hospitalised with mental disorder is common, and represents a significant inequality even in well-developed healthcare systems. Prevention of suicide and cardiovascular disease deserves particular attention in the mentally disordered.

Early European attitudes towards "good death": Eugenios Voulgaris, Treatise on euthanasia, St Petersburg, 1804.

Eugenios Voulgaris (Corfu, Greece, 1716; St Petersburg, Russia, 1806) was an eminent theologian and scholar, and bishop of Kherson, Ukraine. He copiously wrote treatises in theology, philosophy and sciences, greatly influenced the development of modern Greek thought, and contributed to the perception of Western thought throughout the Eastern Christian world. In his Treatise on euthanasia (1804), Voulgaris tried to moderate the fear of death by exalting the power of faith and trust in the divine providence, and by presenting death as a universal necessity, a curative physician and a safe harbour. Voulgaris presented his views in the form of a consoling sermon, abundantly enriched with references to classical texts, the Bible and the Church Fathers, as well as to secular sources, including vital statistics from his contemporary England and France. Besides euthanasia, he introduced terms such as dysthanasia, etoimothanasia and prothanasia. The Treatise on euthanasia is one of the first books, if not the very first, devoted to euthanasia in modern European thought and a remarkable text for the study of the very early European attitudes towards "good death". In the Treatise, euthanasia is clearly meant as a spiritual preparation and reconciliation with dying rather than a physician-related mercy killing, as the term progressed to mean during the 19th and the 20th centuries. This early text is worthy of study not only for the historian of medical ethics or of religious ethics, but for everybody who is trying to courageously confront death, either in private or in professional settings.

Hyperosmotic stresses represent one of the major constraints that adversely affect plants growth, development, and productivity. In this study, the focus was on early responses to hyperosmotic stress- (NaCl and sorbitol) induced reactive oxygen species (ROS) generation, cytosolic Ca(2+) concentration ([Ca(2+)]cyt) increase, ion fluxes, and mitochondrial potential variations, and on their links in pathways leading to programmed cell death (PCD). By using BY-2 tobacco cells, it was shown that both NaCl- and sorbitol-induced PCD seemed to be dependent on superoxide anion (O2·(-)) generation by NADPH-oxidase. In the case of NaCl, an early influx of sodium through non-selective cation channels participates in the development of PCD through mitochondrial dysfunction and NADPH-oxidase-dependent O2·(-) generation. This supports the hypothesis of different pathways in NaCl- and sorbitol-induced cell death. Surprisingly, other shared early responses, such as [Ca(2+)]cyt increase and singlet oxygen production, do not seem to be involved in PCD.

We investigated whether it was possible to predict the prognosis of fetuses with cystic hygroma in early pregnancy based on the degree of neck thickening. We retrospectively analyzed 57 singleton pregnancies with fetuses with cystic hygroma who were examined before the 22nd week of pregnancy. The fetuses were categorized according to the outcome, structural abnormalities at birth, and chromosomal abnormalities. Here, we proposed a new sonographic predictor with which we assessed neck thickening by dividing the width of the neck thickening by the biparietal diameter, which is expressed as the cystic hygroma width/biparietal diameter ratio. The median cystic hygroma width/biparietal diameter ratio in the intrauterine fetal death group (0.51) was significantly higher than that in the live birth group (0.27). No significant difference in the median cystic hygroma width/biparietal diameter ratio was found between the structural abnormalities group at birth and the no structural abnormalities group, and no significant difference in the median cystic hygroma width/biparietal diameter ratio was found between the chromosomal abnormality group and the no chromosomal abnormality group. We used receiver operating characteristic analysis to evaluate the cystic hygroma width/biparietal diameter ratio to predict intrauterine fetal death. When the cystic hygroma width/biparietal diameter ratio cut-off value was 0.5, intrauterine fetal death could be predicted with a sensitivity of 52.9% and a specificity of 100%. It is possible to predict intrauterine fetal death in fetuses with cystic hygroma in early pregnancy if cystic hygroma width/biparietal diameter ratio is measured. However, even if cystic hygroma width/biparietal diameter ratio is measured, predicting the presence or absence of a structural abnormality at birth or a chromosomal abnormality is difficult. © 2018 Japanese Teratology Society.

Donation after cardiac death (DCD) liver allografts have been associated with increased morbidity from primary nonfunction, biliary complications, early allograft failure, cost, and mortality. Early allograft dysfunction (EAD) after liver transplantation has been found to be associated with inferior patient and graft survival. In a cohort of 205 consecutive liver-only transplant patients with allografts from DCD donors at a single center, the incidence of EAD was found to be 39.5%. The patient survival rates for those with no EAD and those with EAD at 1, 3, and 5 years were 97% and 89%, 79% and 79%, and 61% and 54%, respectively (P = 0.009). Allograft survival rates for recipients with no EAD and those with EAD at 1, 3, and 5 years were 90% and 75%, 72% and 64%, and 53% and 43%, respectively (P = 0.003). A multivariate analysis demonstrated a significant association between the development of EAD and the cold ischemia time [odds ratio (OR) = 1.26, 95% confidence interval (CI) = 1.01-1.56, P = 0.037] and hepatocellular cancer as a secondary diagnosis in recipients (OR = 2.26, 95% CI = 1.11-4.58, P = 0.025). There was no correlation between EAD and the development of ischemic cholangiopathy. In conclusion, EAD results in inferior patient and graft survival in recipients of DCD liver allografts. Understanding the events that cause EAD and developing preventive or early therapeutic approaches should be the focus of future investigations. © 2014 American Association for the Study of Liver Diseases.

Diseases of the heart and malignant neoplasms (all-cancers) are the leading causes of death in the United States. The gap between the two has been closing in recent years. To assess the gap status in Texas and to establish a baseline to support evaluation efforts for the Cancer Prevention Research Institute of Texas, mortality data from 2006 to 2009 were analyzed. Immediate cause of death data in Texas for the years 2006-2009 were analyzed and rates developed by sex, race/ethnicity, and four metropolitan counties. Overall, for the years 2006-2009, the age-adjusted mortality rates (AARs) among Texas residents for both diseases of the heart and all-cancers decreased; however, during this time frame, there was greater improvement in diseases of the heart AARs as compared with all-cancers AARs. For the four large metropolitan counties of Bexar, Dallas, Harris, and Travis, data were analyzed by sex and race/ethnicity, and 11 of the 12 largest percent mortality rate decreases were for diseases of the heart. Age-adjusted mortality rates among Texas residents from diseases of the heart are showing improvement as compared with the rates for all-cancers.

The rate of trisomy 13 (47, + 13) in liveborns (ignoring possible biases in studies and heterogeneity in rates) is, with 95% confidence, between 4.6 X 10(-5) (1/21,700) and 14.0 X 10(-5) (1/7,000), with the most likely figure close to 8 X 10(-5) (1/12,000). Numbers are insufficient to construct a comparably narrow confidence interval for translocation cases. The rates of 47, + 13 may be estimated in (1) spontaneous abortuses, about 0.8%--1.0% (100-fold greater than in liveborns); (2) early neonatal deaths, about 0.4% (50-fold greater than in liveborns); and (3) amniocentesis, higher than in liveborns, at least for mothers 40 years and over.

Policy-oriented population health targets, such as the Millennium Development Goals and national targets to address health inequities, are typically based on trends of a decade or less. To test whether expanded timeframes might be more apt, we analyzed 50-year trends in US infant death rates (1960-2010) jointly by income and race/ethnicity. The largest annual per cent changes in the infant death rate (between -4 and -10 per cent), for all racial/ethnic groups, in the lowest income quintile occurred between the mid-1960s and early 1980s, and in the second lowest income quintile between the mid-1960s and 1973. Since the 1990s, these numbers have hovered, in all groups, between -1 and -3 per cent. Hence, to look back only 15 years (in 2014, to 1999) would ignore gains achieved prior to the onset of neoliberal policies after 1980. Target setting should be informed by a deeper and longer-term appraisal of what is possible to achieve.

Purpose Despite advances in childhood cancer care, some patients die soon after diagnosis. This population is not well described and may be under-reported. Better understanding of risk factors for early death and scope of the problem could lead to prevention of these occurrences and thus better survival rates in childhood cancer. Methods We retrieved data from SEER 13 registries on 36,337 patients age 0 to 19 years diagnosed with cancer between 1992 and 2011. Early death was defined as death within 1 month of diagnosis. Socioeconomic status data for each individual's county of residence were derived from Census 2000. Crude and adjusted odds ratios and corresponding 95% CIs were estimated for the association between early death and demographic, clinical, and socioeconomic factors. Results Percentage of early death in the period was 1.5% (n = 555). Children with acute myeloid leukemia, infant acute lymphoblastic leukemia, hepatoblastoma, and malignant brain tumors had the highest risk of early death. On multivariable analysis, an age younger than 1 year was a strong predictor of early death in all disease groups examined. Black race and Hispanic ethnicity were both risk factors for early death in multiple disease groups. Residence in counties with lower than median average income was associated with a higher risk of early death in hematologic malignancies. Percentages of early death decreased significantly over time, especially in hematologic malignancies. Conclusion Risk factors for early death in childhood cancer include an age younger than 1 year, specific diagnoses, minority race and ethnicity, and disadvantaged socioeconomic status. The population-based disease-specific percentages of early death were uniformly higher than those reported in cooperative clinical trials, suggesting that early death is under-reported in the medical literature. Initiatives to identify those at risk and develop preventive interventions should be prioritized.

Motor vehicle crashes are a leading cause of death among children in the United States. Age- and size-appropriate child restraint use is the most effective method for reducing these deaths. CDC analyzed 2002–2011 data from the Fatality Analysis Reporting System to determine the number and rate of motor-vehicle occupant deaths, and the proportion of unrestrained child deaths among children aged <1 year, 1–3 years , 4–7 years, 8–12 years, and for all children aged 0–12 years. Age group–specific death rates and proportions of unrestrained child motor vehicle deaths for 2009–2010 were further stratified by race/ethnicity. Motor vehicle occupant death rates for children declined significantly from 2002 to 2011. However, one third (33%) of children who died in 2011 were unrestrained. Compared with white children for 2009–2010, black children had significantly higher death rates, and black and Hispanic children both had significantly higher proportions of unrestrained child deaths. Motor vehicle occupant deaths among children in the United States have declined in the past decade, but more deaths could be prevented if restraints were always used. Effective interventions, including child passenger restraint laws (with child safety seat/ booster seat coverage through at least age 8 years) and child safety seat distribution plus education programs, can increase restraint use and reduce child motor vehicle deaths.

Approximately 60-80% of patients with congenital central hypothyroidism (CH-C) have multiple pituitary hormone deficiencies (MPHD), making CH-C a potentially life-threatening disease. Data on mortality in CH-C patients, however, are lacking. To study mortality rate in early detected and treated pediatric CH-C patients in the Netherlands and to investigate whether causes of death were related to pituitary hormone deficiencies. Overall mortality rate, infant mortality rate and under-5 mortality rate were calculated in all children with CH-C detected by neonatal screening between 1-1-1995 and 1-1-2013. Medical charts were reviewed to establish causes of death. 139 children with CH-C were identified, of which 138 could be traced (82 MPHD/56 isolated CHC). Total observation time was 1414 years with a median follow up duration of 10.2 years. The overall mortality rate was 10.9% (15/138). Infant mortality rate (IMR) and under-5 mortality rate were 65.2/1000 (9/138) and 101.4/1000 (14/138), respectively, compared to an IMR of 4.7/1000 and under-5 mortality of 5.4/1000 live born children in the Netherlands during the same time period (p<0.0001). Main causes of death were severe congenital malformations in six patients, asphyxia in two patients, and congenital or early neonatal infection in two patients. Pituitary hormone deficiency was noted as cause of death in only one infant. We report an increased mortality rate in early detected CH-C patients which does not seem to be related to endocrine disease. This suggests that mortality due to pituitary insufficiency is low in an early detected and treated CH-C population.

2014-01-01

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.

The purpose of this study was to examine US accidental poisoning death rates by demographic and geographic factors from 1979 to 2014, including High Intensity Drug Trafficking Areas. Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 9th revision: E850-E869; ICD 10th revision: X40-X49) from 1979 to 2014 using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 2014 to 1979, overall, by sex, age group, race, and county. Joinpoint regression detected changes in trends and calculated the average annual percentage change (AAPC) as a summary measure of trend. Drug poisoning mortality rates have risen an average of 6% per year since 1979. Increases are occurring in all ages 15+, and in all race-sex groups. HIDTA counties with the highest mortality rates were in Appalachia and New Mexico. Many of the HIDTA border counties had lower rates of mortality. The drug poisoning mortality epidemic is continuing to grow. While HIDTA resources are appropriately targeted at many areas in the US most affected, rates are also rapidly rising in some non-HIDTA areas. Copyright © 2016 Elsevier Inc. All rights reserved.

Deciphering early events involved in hyperosmotic stress-induced programmed cell death in tobacco BY-2 cells

PubMed Central

Monetti, Emanuela; Kadono, Takashi; Bouteau, François

2014-01-01

Hyperosmotic stresses represent one of the major constraints that adversely affect plants growth, development, and productivity. In this study, the focus was on early responses to hyperosmotic stress- (NaCl and sorbitol) induced reactive oxygen species (ROS) generation, cytosolic Ca2+ concentration ([Ca2+]cyt) increase, ion fluxes, and mitochondrial potential variations, and on their links in pathways leading to programmed cell death (PCD). By using BY-2 tobacco cells, it was shown that both NaCl- and sorbitol-induced PCD seemed to be dependent on superoxide anion (O2·–) generation by NADPH-oxidase. In the case of NaCl, an early influx of sodium through non-selective cation channels participates in the development of PCD through mitochondrial dysfunction and NADPH-oxidase-dependent O2·– generation. This supports the hypothesis of different pathways in NaCl- and sorbitol-induced cell death. Surprisingly, other shared early responses, such as [Ca2+]cyt increase and singlet oxygen production, do not seem to be involved in PCD. PMID:24420571

Heart rate variability regression and risk of sudden unexpected death in epilepsy.

PubMed

Galli, Alessio; Lombardi, Federico

2017-02-01

The exact mechanisms of sudden unexpected death in epilepsy remain elusive, despite there is consensus that SUDEP is associated with severe derangements in the autonomic control to vital functions as breathing and heart rate regulation. Heart rate variability (HRV) has been advocated as biomarker of autonomic control to the heart. Cardiac dysautonomia has been found in diseases where other branches of the autonomous nervous system are damaged, as Parkinson disease and multiple system atrophy. In this perspective, an impaired HRV not only is a risk factor for sudden cardiac death mediated by arrhythmias, but also a potential biomarker for monitoring a progressive decline of the autonomous nervous system. This slope may lead to an acute imbalance of the regulatory pathways of vital functions after seizure and then to SUDEP. Copyright © 2016 Elsevier Ltd. All rights reserved.

Although acute promyelocytic leukemia (APL) is a curable hematologic malignancy, early death (ED) remains a significant cause of treatment failure especially in developing countries. In a retrospective data analysis of 67 adult APL patients diagnosed in United Arab Emirates we report an ED rate of 11.9% which is comparable to that reported from more developed countries. We identified the following parameters at presentation as significant predictor of increased ED: Age >40 years (P = 0.015), fever (P = 0.030), WBC count >20 × 10 9 /L (P = 0.010), the breakpoints other than bcr1 (P = 0.043) and fibrinogen level <1.5 g/L (P = 0.025). Delay in ATRA administration beyond 24 h from admission and fibrinogen <150 mg/dL were also significant predictors of ED, but only among high-risk patients (P = 0.035 and P = 0.033, respectively). WBC count >10 × 10 9 /L and expression of HLA-DR (P = 0.018) or CD2 (P = 0.017) were significant predictors for differentiation syndrome (DS) which was found to be a predictor of ED (P = 0.002). Reducing the APL related ED rate in centers with limited resources is feasible provided early initiation of ATRA administration and early correction of coagulopathy in high-risk patients in addition to prompt treatment of DS. To our knowledge this is the first report from the Arabian Gulf describing ED in APL.

One thousand consecutive in-hospital deaths following severe injury: Has the etiology of traumatic inpatient death changed in Canada?

Summary A wide range of factors have traditionally led to early in-hospital death following severe injury. The primary goal of this commentary was to evaluate the causes of early posttraumatic inpatient deaths over an extended period. Although early posttraumatic in-hospital death remains multifactorial, severe traumatic brain injuries are the dominant cause and have increased in proportion over time. Other traditional causes of death have also decreased owing to improved clinical care. PMID:29806810

Why history matters for quantitative target setting: long-term trends in socioeconomic and racial/ethnic inequities in US infant death rates (1960–2010)

2016-01-01

Policy-oriented population health targets, such as the Millennium Development Goals and national targets to address health inequities, typically are based on trends of a decade or less. To test whether expanded timeframes might be more apt, we analyzed 50-year trends in US infant death rates (1960–2010) jointly by income and race/ethnicity. The largest annual percent changes in the infant death rate (between −4% and −10%) occurred, for all racial/ethnic groups, in the lowest income quintile between the mid-1960s and early 1980s, and in the second lowest income quintile between the mid-1960s and 1973; since the 1990s, they have hovered, in all groups, between −1% and −3%. Hence, to look back only 15 years, in 2014, to 1999, would ignore gains achieved prior to the post-1980 onset of neoliberal policies. Target setting should be informed by a deeper and more long-term appraisal of what is possible to achieve. PMID:25971237

Sucrose modulation of radiofrequency-induced heating rates and cell death.

Applied radiofrequency (RF) energy induces hyperthermia in tissues, facilitating vascular perfusion This study explores the impact of RF radiation on the integrity of the luminal endothelium, and then predominately explores the impact of altering the conductivity of biologically-relevant solutions on RF-induced heating rates and cell death. The ability of cells to survive high sucrose (i.e. hyperosmotic conditions) to achieve lower conductivity as a mechanism for directing hyperthermia is evaluated. RF radiation was generated using a capacitively-coupled radiofrequency system operating at 13.56 MHz. Temperatures were recorded using a FLIR SC 6000 infrared camera. RF radiation reduced cell-to-cell connections among endothelial cells and altered cell morphology towards a more rounded appearance at temperatures reported to cause in vivo vessel deformation. Isotonic solutions containing high sucrose and low levels of NaCl displayed low conductivity and faster heating rates compared to high salt solutions. Heating rates were positively correlated with cell death. Addition of sucrose to serum similarly reduced conductivity and increased heating rates in a dose-dependent manner. Cellular proliferation was normal for cells grown in media supplemented with 125 mM sucrose for 24 hours or for cells grown in 750 mM sucrose for 10 minutes followed by a 24 h recovery period. Sucrose is known to form weak hydrogen bonds in fluids as opposed to ions, freeing water molecules to rotate in an oscillating field of electromagnetic radiation and contributing to heat induction. The ability of cells to survive temporal exposures to hyperosmotic (i.e. elevated sucrose) conditions creates an opportunity to use sucrose or other saccharides to selectively elevate heating in specific tissues upon exposure to a radiofrequency field.

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

Hip fracture mortality. A prospective, multifactorial study to predict and minimize death risk.

PubMed

Mullen, J O; Mullen, N L

1992-07-01

Four hundred consecutive hip fractures were studied prospectively. Two hundred forty-seven patients were classified as unhealthy (poor cardiac status, pneumonia, cancer history, bowel obstruction history, malnutrition, dehydration, stroke history, renal failure history, cirrhosis). Twenty-two percent of this unhealthy group died, while only 6% of the remaining healthy group died. Death rates varied with admission activity level and mental status but not when patient health status was factored out. After factoring out health status, age was associated with higher death rates only in patients older than age 85. Confusion, a change of mental status in the hospital, occurred in 25% of patients. Confusion was associated with a medical complication in 94% of cases, was the presenting symptom of a medical complication in 79% of cases, and was associated with a 39% death rate. Major medical complications occurred in 9% of the healthy group (29% of them died) and 21% of the unhealthy group (64% of them died). Major medical complications in unhealthy, shut-in patients were associated with an 80% death rate. Vigorous urinary tract monitoring and early treatment of bacteriuria decreased death rate. Postfracture malnutrition was associated with higher complication rates. Hip surgery performed within 72 hours on patients with acute medical illnesses in addition to their fracture was associated with a higher death rate. Whether a patient walked postfracture seemed not to be correlated with the death rate. Patients who were not walking prefracture but treated by internal fixation had a 34% failure rate.

Although survival of elderly myeloma patients has significantly improved there is still a subset of patients who, despite being fit and achieving optimal responses, will die within 2 years of diagnosis due to myeloma progression. The objective of this study was to define a scoring prognostic index to identify this group of patients. We have evaluated the outcome of 490 newly diagnosed elderly myeloma patients included in two Spanish trials (GEM2005-GEM2010). Sixty-eight patients (13.8%) died within 2 years of diagnosis (early deaths) due to myeloma progression. Our study shows that the use of simple scoring model based on 4 widely available markers (elevated LDH, ISS 3, high risk CA or >75 years) can contribute to identify up-front these patients. Moreover, unsustained response (<6 months duration) emerged as one important predictor of early myeloma-related mortality associated with a significant increase in the risk of death related to myeloma progression. The identification of these patients at high risk of early death is relevant for innovative trials aiming to maintain the depth of first response, since many of them will not receive subsequent lines of therapy.

Blacks' Death Rate Due to Circulatory Diseases Is Positively Related to Whites' Explicit Racial Bias.

2016-10-01

Perceptions of racial bias have been linked to poorer circulatory health among Blacks compared with Whites. However, little is known about whether Whites' actual racial bias contributes to this racial disparity in health. We compiled racial-bias data from 1,391,632 Whites and examined whether racial bias in a given county predicted Black-White disparities in circulatory-disease risk (access to health care, diagnosis of a circulatory disease; Study 1) and circulatory-disease-related death rate (Study 2) in the same county. Results revealed that in counties where Whites reported greater racial bias, Blacks (but not Whites) reported decreased access to health care (Study 1). Furthermore, in counties where Whites reported greater racial bias, both Blacks and Whites showed increased death rates due to circulatory diseases, but this relationship was stronger for Blacks than for Whites (Study 2). These results indicate that racial disparities in risk of circulatory disease and in circulatory-disease-related death rate are more pronounced in communities where Whites harbor more explicit racial bias.

2017-05-12

In 2015, mortality from alcohol-induced causes reached the highest rate during 1999-2015 of 9.1 deaths per 100,000 U.S. standard population. Alcohol-induced death rates for the Hispanic population remained the highest (9.9 per 100,000 U.S. standard population), followed by the non-Hispanic white population (9.6). For the non-Hispanic black population, the alcohol-induced death rate decreased 33% from 1999 to 2015, while the rate increased by 50% during the same period for the non-Hispanic white population. Overall, from 1999 to 2015, mortality from alcohol-induced causes increased 28% (7.1 to 9.1).

Stroke/Death Rates Following Carotid Artery Stenting and Carotid Endarterectomy in Contemporary Administrative Dataset Registries: A Systematic Review.

PubMed

Paraskevas, K I; Kalmykov, E L; Naylor, A R

2016-01-01

Randomised trials have reported higher stroke/death rates after carotid artery stenting (CAS) versus carotid endarterectomy (CEA). Despite this, the 2011 American Heart Association (AHA) guidelines expanded CAS indications, partly because of the Carotid Revascularization Endarterectomy versus Stenting Trial, but also because of improving outcomes in industry sponsored CAS Registries. The aim of this systematic review was: (i) to compare stroke/death rates after CAS/CEA in contemporary dataset registries, (ii) to examine whether published stroke/death rates after CAS fall within AHA thresholds, and, (iii) to see if there had been a decline (over time) in procedural risk after CAS/CEA. PubMed/Medline, Embase, and Cochrane databases were systematically searched according to the recommendations of the PRISMA statement from January 1, 2008 until February 23, 2015 for administrative dataset registries reporting outcomes after both CEA and CAS. Twenty-one registries reported outcomes involving more than 1,500,000 procedures. Stroke/death after CAS was significantly higher than after CEA in 11/21 registries (52%) involving "average risk for CEA" asymptomatic patients and in 11/18 registries (61%) involving "average risk for CEA" symptomatic patients. In another five registries, CAS was associated with higher stroke/death rates than CEA for both symptomatic and asymptomatic patients, but formal statistical comparison was not reported. CAS was associated with stroke/death rates that exceeded risk thresholds recommended by the AHA in 9/21 registries (43%) involving "average risk for CEA" asymptomatic patients and in 13/18 registries (72%) involving "average risk for CEA" symptomatic patients. In 5/18 registries (28%), the procedural risk after CAS in "average risk" symptomatic patients exceeded 10%. Data from contemporary administrative dataset registries suggest that stroke/death rates following CAS remain significantly higher than after CEA and often exceed accepted AHA

Trauma-related deaths remain an important public health problem. One group susceptible to death due to traumatic mechanisms is US law enforcement (LE). We hypothesized that LE officers experienced a higher chance of violent death compared with the general US population and that risks have increased over time. The National Institute on Occupational Safety and Health National Occupational Mortality Surveillance is a population-based survey of occupational deaths. It includes data for workers who died during 1985 to 1998 in one of 30 US states (EARLY period). Additional deaths were added from 23 US states in 1999, 2003 to 2004, 2007 to 2010 (LATE period). Mortality rates are estimated by calculating proportionate mortality ratios (PMR). A PMR above 100 is considered to exceed the average background risk for all occupations. All adults older than 18 years whose primary occupation was listed as "law enforcement worker" were included in the analysis. Law enforcement personnel were more likely to die from an injury compared with the general population (Fig. 1). The overall PMR for injury in EARLY was 111 (95% confidence interval [CI], 108-114; p < 0.01), and for LATE was 118 (95% CI, 110-127; p < 0.01). Four mechanisms of death reached statistical significance: motor vehicle traffic (MVT)-driver, MVT-other, intentional self-harm, and assault/homicide. The highest PMR in EARLY was associated with firearms (PMR, 272; 95% CI, 207-350; p < 0.01). The highest PMR in LATE was associated with death due to being a driver in an MVT (PMR, 194; 95% CI, 169-222; p < 0.01). There were differences in risk of death by race and sex. White females had the highest PMR due to assault and homicide (PMR, 317; 95% CI, 164-554; p < 0.01). All groups had similar risks of death due to intentional self-harm (PMR, 130-171). The risk of death for US LE officers is high and increasing over time, suggesting an at-risk population that requires further interventions. Targeted efforts based on risk

Offspring of psychiatric inpatients are at higher risk of death from all causes, but their cause-specific risks have not been quantified. To investigate cause-specific deaths at 1 to 25 years in offspring of parents previously admitted as psychiatric inpatients. Population-based cohort study. The entire Danish population. All singleton births (N = 1.38 million) from January 1, 1973, to December 31, 1997, with follow-up to January 1, 1999. Linkage to the national psychiatric register identified all previous parental admissions. Deaths from all natural causes and all unnatural causes, specifically, accidents, homicides, suicides, and undetermined causes. The highest observed relative risk (RR) was for homicide in young and older children with affected mothers or fathers. Homicides were between 5 and 10 times more likely to occur in this group, according to child's age and whether the mother or father had been admitted. There was previous parental admission in approximately one third of all child homicides. We found no evidence of increased risk of homicide in exposed young adults, but this group had a 2-fold to 3-fold higher risk of suicide. In almost one fourth of the suicides, there was a history of parental admission. Young adults with 2 previously admitted parents were 6 times more likely to kill themselves than were their peers in the general population. Relative risk of suicide or open-verdict deaths by poisoning were higher than for such deaths occurring by other means. Almost 99% of children studied survived to their mid-20s. However, they were more vulnerable to death from unnatural causes, notably, homicide during childhood and suicide in early adulthood. Further research is needed to establish how parental psychopathology contributes to increased risk of premature death in these offspring.

We used race-corrected data and comprehensive diagnostic codes to better compare HIV and tuberculosis (TB) mortality from 1999 to 2009 between American Indian/Alaska Natives (AI/ANs) and Whites. National Vital Statistics Surveillance System mortality data were adjusted for AI/AN racial misclassification through linkage with Indian Health Service registration records. We compared average annual 1990 to 2009 HIV and TB death rates (per 100,000 people) for AI/AN persons with those for Whites; Hispanics were excluded. Although death rates from HIV in AI/AN persons were significantly lower than those in Whites from 1990 to 1998 (4.2 vs 7.0), they were significantly higher than those in Whites from 1999 to 2009 (3.6 vs 2.0). Death rates from TB in AI/AN persons were significantly higher than those in Whites, with a significant disparity during both 1990 to 1998 (3.3 vs 0.3) and 1999 to 2009 (1.5 vs 0.1). The decrease in death rates from HIV and TB was greater among Whites, and death rates remained significantly higher among AI/AN individuals. Public health interventions need to be prioritized to reduce the TB and HIV burden and mortality in AI/AN populations.

QuickStats: Death Rates for Motor Vehicle Traffic Injury,* Suicide,† and Homicide§ Among Children and Adolescents aged 10-14 Years - United States, 1999-2014.

PubMed

2016-11-04

In 1999, the mortality rate for children and adolescents aged 10-14 years for deaths from motor vehicle traffic injury (4.5 per 100,000) was about four times higher than the rate for deaths for suicide and homicide (both at 1.2). From 1999 to 2014, the death rate for motor vehicle traffic injury declined 58%, to 1.9 in 2014 (384 deaths). From 1999 to 2007, the death rate for suicide fluctuated and then doubled from 2007 (0.9) to 2014 (2.1, 425 deaths). The death rate for homicide gradually declined to 0.8 in 2014. In 2013 and 2014, the differences between death rates for motor vehicle traffic injury and suicide were not statistically significant.

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

Density behavior of spatial birth-and-death stochastic evolution of mutating genotypes under selection rates

We consider birth-and-death stochastic evolution of genotypes with different lengths. The genotypes might mutate, which provides a stochastic changing of lengths by a free diffusion law. The birth and death rates are length dependent, which corresponds to a selection effect. We study an asymptotic behavior of a density for an infinite collection of genotypes. The cases of space homogeneous and space heterogeneous densities are considered.

OBJECTIVE: To determine the association between measures of medical manpower available to treat trauma patients and county trauma death rates in the United States. The primary hypothesis was that greater availability of medical manpower to treat trauma injury would be associated with lower trauma death rates. SUMMARY BACKGROUND DATA: When viewed from the standpoint of the number of productive years of life lost, trauma has a greater effect on health care and lost productivity in the United States than any disease. Allocation of health care manpower to treat injuries seems logical, but studies have not been done to determine its efficacy. The effect of medical manpower and hospital resource allocation on the outcome of injury in the United States has not been fully explored or adequately evaluated. METHODS: Data on trauma deaths in the United States were obtained from the National Center for Health Statistics. Data on the number of surgeons and emergency medicine physicians were obtained from the American Hospital Association and the American Medical Association. Data on physicians who have participated in the American College of Surgeons (ACS) Advanced Trauma Life Support Course (ATLS) were obtained from the ACS. Membership information for the American Association for Surgery of Trauma (AAST) was obtained from that organization. Demographic data were obtained from the United States Census Bureau. Multivariate stepwise linear regression and cluster analysis were used to model the county trauma death rates in the United States. The Statistical Analysis System (Cary, NC) for statistical analysis was used. RESULTS: Bivariate and multivariate analyses showed that a variety of medical manpower measures and demographic factors were associated with county trauma death rates in the United States. As in other studies, measures of low population density and high levels of poverty were found to be strongly associated with increased trauma death rates. After accounting for

Clinical outcomes of transfemoral-transcatheter aortic valve implantation (TF-TAVI) versus surgical aortic valve replacement (SAVR) or transapical (TA)-TAVI are limited to a few randomized clinical trials (RCTs). Because previous meta-analyses only included a limited number of adjusted studies or several non-adjusted studies, our goal was to compare and summarize the outcomes of TF-TAVI vs SAVR and TF-TAVI vs TA-TAVI exclusively with the RCT and propensity-matched cohort studies with direct and adjusted indirect comparisons to reach more precise conclusions. We hypothesized that TF-TAVI would offer surgical candidates a better outcome compared with SAVR and TA-TAVI because of its potential for fewer myocardial injuries. A literature search was conducted through PUBMED and EMBASE through June 2016. Only RCTs and propensity-matched cohort studies were included. A direct meta-analysis of TF-TAVI vs SAVR, TA-TAVI vs SAVR and TF-TAVI vs TA-TAVI was conducted. Then, the effect size of an indirect meta-analysis was calculated from the direct meta-analysis. The effect sizes of direct and indirect meta-analyses were then combined. A random-effects model was used to calculate the hazards ratio and the odds ratio with 95% confidence intervals. Early (in-hospital or 30 days) and mid-term (≥1 year) all-cause mortality rates were assessed. Our search resulted in 4 RCTs (n = 2319) and 14 propensity-matched cohort (n = 7217) studies with 9536 patients of whom 3471, 1769 and 4296 received TF, TA and SAVR, respectively. Direct meta-analyses and combined direct and indirect meta-analyses of early and mid-term deaths with TF-TAVI and SAVR were similar. Early deaths with TF-TAVI vs TA-TAVI were comparable in direct meta-analyses (odds ratio 0.64, P = 0.35) and direct and indirect meta-analyses combined (odds ratio 0.73, P = 0.24). Mid-term deaths with TF-TAVI vs TA-TAVI were increased (hazard ratio 0.83, P = 0.07) in a direct meta-analysis and became significant

Previous meta-analyses examined the effectiveness of interventions for bereaved children showing small to moderate effect sizes. However, no mixed methods systematic review was conducted on bereavement interventions following the loss of a parent focusing on the time since death in regard to the prevention of grief complications. The overall purpose of the review is to provide a rigorous synthesis of early intervention after parental death in childhood. Specifically, the aims are twofold: (1) to determine the rationales, contents, timeframes, and outcomes of early bereavement care interventions for children and/or their parents and (2) to assess the quality of current early intervention studies. Quantitative, qualitative, and mixed methods intervention studies that start intervention with parentally bereaved children (and/or their parents) up to 6 months postloss will be included in the review. The search strategy was based on the Population, Interventions, Comparator, Outcomes, and Study Designs (PICOS) approach, and it was devised together with a university librarian. The literature searches will be carried out in the Medical Literature Analysis and Retrieval System Online (MEDLINE), PsycINFO, Excerpta Medica Database (EMBASE), and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The Mixed Methods Appraisal Tool will be used to appraise the quality of eligible studies. All data will be narratively synthetized following the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews. The systematic review is ongoing and the data search has started. The review is expected to be completed by the end of 2017. Findings will be submitted to leading journals for publication. In accordance with the current diagnostic criteria for prolonged grief as well as the users' perspectives literature, this systematic review outlines a possible sensitive period for early intervention following the death of a parent. The hereby presented protocol ensures

Florfenicol induces early embryonic death in eggs collected from treated hens.

PubMed

Al-Shahrani, S; Naidoo, V

2015-08-18

Florfenicol, a commonly used veterinary antibiotic, was reported to have caused a severe drop in egg hatchability following its off-label use on a broiler breeder farm in South Africa. According to the pharmacovigilance report, hatchability dropped by 80 % for up to a week following a five day course at 10 mg/kg (both males and females treated metaphylactically) to manage an Escherichia coli infection. While mammalian toxicity studies indicate the potential for early embryonic death in utero or testicular damage, no literature is available on the avian toxicity of florfenicol. For this study we investigated the effects of florfenicol at various doses from 10 to 90 mg/kg on the egg hatchability in a breeder flock we kept and established under controlled conditions, with the same cockerels and hens being exposed in a phased manner. Following five days of oral exposure, no toxic signs were evident in any of the cockerels or hens treated at doses up to 90 mg/kg. Treatment of only the cockerels had no effect on egg hatchability, while treatment of only the hens at doses of 60 and 90 mg/kg resulted in decreased hatchability of 0 % in comparison to 70 % of the control as early 24 h after treatment. In all cases, decreased hatchability was associated with embryonic death at 5 days of development. The toxic effects of florfenicol were completely reversible with comparable hatchability being present by day 4 post-treatment withdrawal. Toxicity correlated with total egg florfenicol concentrations with an LC50 of 1.07 μg/g. Florfenicol appears to be toxic to the developing chick embryo at around day 5 of incubation, in the absence of related toxicity in the hen or cockerel.

This study describes ecological associations between self-inflicted death rates and prison-level environmental indicators over the period 2000-2002 in England and Wales. The objective was to assist in the development of interventions for reducing the incidence of self-inflicted deaths in prisons in England and Wales, by identifying risk factors, including overcrowding, positive drug tests, the number of assaults, purposeful activity, offending behaviour programmes, and cost per prisoner. Poisson regression was used to estimate associations between self-inflicted death rates and these potential risk factors, controlling for different categories of prison. The annual rate of self-inflicted death during 2000-2002 was 1.14 per 1000 (95% CI 0.98 to 1.34), with no evidence for a difference in the two years. Highest rates were in the Male Local and Women's prisons at 1.86 (95% CI 1.42 to 2.26) and 2.27 (95% CI 1.35 to 3.84) per 1000 respectively. In a multivariate analysis, overcrowding, assault rate and purposeful activity were significant. In an analysis controlling also for prison category, only purposeful activity remained independently significant, as a protective factor (RR 0.57, 95% CI 0.35 to 0.92, p=0.02) with weaker evidence for a positive association with positive drug tests (RR 1.41, 95% CI 0.96 to 2.05, p=0.08). Despite concerns about the quality of routinely collected data and the interpretation of ecological associations, this study suggests that a higher level of purposeful activity is independently associated with lower rates of self-inflicted death, whatever the prison category. This adds support to other studies conducted at the level of the individual prisoner.

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

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.

In the present study, we sought to identify rates, causes, and predictors of death among male and female injection drug users (IDUs) in Vancouver, British Columbia, Canada, during a period of expanded public health interventions. Data from prospective cohorts of IDUs in Vancouver were linked to the provincial database of vital statistics to ascertain rates and causes of death between 1996 and 2011. Mortality rates were analyzed using Poisson regression and indirect standardization. Predictors of mortality were identified using multivariable Cox regression models stratified by sex. Among the 2,317 participants, 794 (34.3%) of whom were women, there were 483 deaths during follow-up, with a rate of 32.1 (95% confidence interval (CI): 29.3, 35.0) deaths per 1,000 person-years. Standardized mortality ratios were 7.28 (95% CI: 6.50, 8.14) for men and 15.56 (95% CI: 13.31, 18.07) for women. During the study period, mortality rates related to infection with human immunodeficiency virus (HIV) declined among men but remained stable among women. In multivariable analyses, HIV seropositivity was independently associated with mortality in both sexes (all P < 0.05). The excess mortality burden among IDUs in our cohorts was primarily attributable to HIV infection; compared with men, women remained at higher risk of HIV-related mortality, indicating a need for sex-specific interventions to reduce mortality among female IDUs in this setting.

The leading causes of infant death vary by age at death but were consistent from 2005 to 2015 (1-6). Previous research shows higher infant mortality rates in rural counties compared with urban counties and differences in cause of death for individuals aged 1 year and over by urbanization level (4,5,7,8). No research, however, has examined if mortality rates from the leading causes of infant death differ by urbanization level. This report describes the mortality rates for the five leading causes of infant, neonatal, and postneonatal death in the United States across rural, small and medium urban, and large urban counties defined by maternal residence, as reported on the birth certificate for combined years 2013-2015.

Near-death experiences are an ancient and very common phenomenon that spans from ancient philosophy, religion and healing to the most modern clinical practice of medicine.

Puzzling cases of near-death experiences continue to come to light and the ancient debate about what they mean continues unabated.

Changing epidemiology of trauma deaths leads to a bimodal distribution

2010-01-01

Injury mortality was classically described with a trimodal distribution, with immediate deaths at the scene, early deaths due to hemorrhage, and late deaths from organ failure. We hypothesized that the development of trauma systems has improved prehospital care, early resuscitation, and critical care and altered this pattern. This population-based study of all trauma deaths in an urban county with a mature trauma system reviewed data for 678 patients (median age, 33 years; 81% male; 43% gunshot, 20% motor vehicle crashes). Deaths were classified as immediate (scene), early (in hospital, ≤4 hours from injury), or late (>4 hours after injury). Multinomial regression was used to identify independent predictors of immediate and early versus late deaths, adjusted for age, gender, race, intention, mechanism, toxicology, and cause of death. Results showed 416 (61%) immediate, 199 (29%) early, and 63 (10%) late deaths. Compared with the classical description, the percentage of immediate deaths remained unchanged, and early deaths occurred much earlier (median 52 vs 120 minutes). However, unlike the classic trimodal distribution, the late peak was greatly diminished. Intentional injuries, alcohol intoxication, asphyxia, and injuries to the head and chest were independent predictors of immediate death. Alcohol intoxication and injuries to the chest were predictors of early death, while pelvic fractures and blunt assaults were associated with late deaths. In conclusion, trauma deaths now have a predominantly bimodal distribution. Near elimination of the late peak likely represents advancements in resuscitation and critical care that have reduced organ failure. Further reductions in mortality will likely come from prevention of intentional injuries and injuries associated with alcohol intoxication. PMID:20944754

Motor neuron disease mortality and lifetime petrol lead exposure: Evidence from national age-specific and state-level age-standardized death rates in Australia.

The age standardized death rate from motor neuron disease (MND) for persons 40-84 years of age in the Australian States of New South Wales, Victoria, and Queensland increased dramatically from 1958 to 2013. Nationally, age-specific MND death rates also increased over this time period, but the rate of the rise varied considerably by age-group. The historic use of lead (Pb) additives in Australian petrol is a candidate explanation for these trends in MND mortality (International Classification of Disease (ICD)-10 G12.2). Leveraging temporal and spatial variation in petrol lead exposure risk resulting from the slow rise and rapid phase-out of lead as a constituent in gasoline in Australia, we analyze relationships between (1) national age-specific MND death rates in Australia and age-specific lifetime petrol lead exposure, (2) annual between-age dispersions in age-specific MND death rates and age-specific lifetime petrol lead exposure; and (3) state-level age-standardized MND death rates as a function of age-weighted lifetime petrol lead exposure. Other things held equal, we find that a one percent increase in lifetime petrol lead exposure increases the MND death rate by about one-third of one percent in both national age-specific and state-level age-standardized models of MND mortality. Lending support to the supposition that lead exposure is a driver of MND mortality risk, we find that the annual between-age group standard deviation in age-specific MND death rates is strongly correlated with the between-age standard deviation in age-specific lifetime petrol lead exposure. Legacy petrol lead emissions are associated with age-specific MND death rates as well as state-level age-standardized MND death rates in Australia. Results indicate that we are approaching peak lead exposure-attributable MND mortality. Copyright © 2016 Elsevier Inc. All rights reserved.

Lecithin:cholesterol acyltransferase (LCAT) is thought to be important in reverse cholesterol transport. However, its association with coronary heart disease (CHD) and sudden death is controversial. We prospectively studied 1927 individuals from the general population. Serum concentrations of apolipoprotein A-I, A-II, B, C-II, C-III, E, and LCAT activity measured as a serum cholesterol esterification rate were evaluated. We documented 61 events of CHD and sudden death during 10.9 years of follow-up. After adjustment for age and sex, LCAT activity was significantly associated with the risk of CHD and sudden death (hazard ratio, 3.02; 95% confidence interval, 1.49-6.12; P=0.002). In multivariate analysis adjusted for age, sex, current smoking status, history of diabetes mellitus, body mass index, systolic blood pressure, serum total cholesterol, and serum high-density lipoprotein cholesterol concentrations, the hazard ratio of LCAT activity for the risk of CHD and sudden death remained significant (hazard ratio, 3.07; 95% confidence interval, 1.35-7.01; P=0.008). However, when it was analyzed for men and women separately, this association remained significant only in women. Increased LCAT activity measured as a serum cholesterol esterification rate was a risk for CHD and sudden death in a Japanese general population.

Cell death and morphogenesis during early mouse development: Are they interconnected?

PubMed Central

Bedzhov, Ivan; Zernicka-Goetz, Magdalena

Shortly after implantation the embryonic lineage transforms from a coherent ball of cells into polarized cup shaped epithelium. Recently we elucidated a previously unknown apoptosis-independent morphogenic event that reorganizes the pluripotent lineage. Polarization cues from the surrounding basement membrane rearrange the epiblast into a polarized rosette-like structure, where subsequently a central lumen is established. Thus, we provided a new model revising the current concept of apoptosis-dependent epiblast morphogenesis. Cell death however has to be tightly regulated during embryogenesis to ensure developmental success. Here, we follow the stages of early mouse development and take a glimpse at the critical signaling and morphogenic events that determine cells destiny and reshape the embryonic lineage.

Dictyostelium cell death

Cell death in the stalk of Dictyostelium discoideum, a prototypic vacuolar cell death, can be studied in vitro using cells differentiating as a monolayer. To identify early events, we examined potentially dying cells at a time when the classical signs of Dictyostelium cell death, such as heavy vacuolization and membrane lesions, were not yet apparent. We observed that most cells proceeded through a stereotyped series of differentiation stages, including the emergence of “paddle” cells showing high motility and strikingly marked subcellular compartmentalization with actin segregation. Paddle cell emergence and subsequent demise with paddle-to-round cell transition may be critical to the cell death process, as they were contemporary with irreversibility assessed through time-lapse videos and clonogenicity tests. Paddle cell demise was not related to formation of the cellulose shell because cells where the cellulose-synthase gene had been inactivated underwent death indistinguishable from that of parental cells. A major subcellular alteration at the paddle-to-round cell transition was the disappearance of F-actin. The Dictyostelium vacuolar cell death pathway thus does not require cellulose synthesis and includes early actin rearrangements (F-actin segregation, then depolymerization), contemporary with irreversibility, corresponding to the emergence and demise of highly polarized paddle cells.

The rationing of medical care prioritizes the need for early predictors of death in the surgical intensive care unit (SICU). We prospectively studied 100 consecutive SICU admissions, looking for predictors of early death in the SICU and the cost implications of these findings. Serial APACHE II scores on days 1, 3, and 5 were subjected to multinomial logistic regression analysis to determine significant predictors of death in the SICU on day 1. Survivors had significantly lower (p less than 0.05) mean day-1 APACHE II scores than had nonsurvivors (13.6 vs 22.1). Half of the patients with scores greater than 18 died, and all patients with scores on day 1 of 25 or greater died. Significant predictors of death on SICU day 1 were APACHE II scores, Acute Physiology Score, Glasgow Coma Score, creatinine level, and Chronic Health Evaluation Score. Forty-one patients had been transferred from community hospitals as a results of acute illness; this population accounted for two thirds of the deaths in the SICU. Ten of 18 nonsurvivors were predicted on day 1, with these patients incurring a total cost of approximately $1 million. If therapy had been modified on days 5, 10, or 15, the potential cost savings would have been $340,000, $240,000, or $140,000, respectively. Integration of the results of this study into the management decision-making process and treatment guidelines may reduce the cost of care in the SICU.

Increased intracranial pressure following trauma and subsequent possible development of brain death are important factors for morbidity and mortality due to ischemic changes. We aimed to establish the role of ischemic modified albumin (IMA) in the early diagnosis of the process, starting with increased intracranial pressure and ending with brain death. Eighteen Wistar-Albino rats were divided into three groups; control (CG, n = 6), increased intracranial pressure (ICPG, n = 6), and brain death (BDG, n = 6). Intracranial pressure elevation and brain death were constituted with the inflation of a balloon of a Fogarty catheter in the epidural space. In all three groups, blood samples were drawn before the procedure, and at minutes 150 and 240 for IMA and malondialdehyde (MDA) analysis. Serum IMA levels at 150 and 240 minutes were higher in ICPG than in CG (p < 0.05). IMA levels were similar in ICPG and BDG. Serum MDA levels at 150 and 240 minutes increased in ICPG and BDG groups compared to CG (p < 0.05). MDA levels were similar in ICP and BD groups. IMA should be considered as a biochemical parameter in the process starting from increased intracranial pressure elevation and ending at brain death (Tab. 3, Fig. 5, Ref. 31).

A great number of obsolete larval neurons in the Drosophila central nervous system are eliminated by developmentally programmed cell death (PCD) during early metamorphosis. To elucidate the mechanisms of neuronal PCD occurring during this period, we undertook genetic dissection of seven currently known Drosophila caspases in the PCD of a group of interneurons (vCrz) that produce corazonin (Crz) neuropeptide in the ventral nerve cord. The molecular death program in the vCrz neurons initiates within 1 hour after pupariation, as demonstrated by the cytological signs of cell death and caspase activation. PCD was significantly suppressed in dronc-null mutants, but not in null mutants of either dredd or strica. A double mutation lacking both dronc and strica impaired PCD phenotype more severely than did a dronc mutation alone, but comparably to a triple dredd/strica/dronc mutation, indicating that dronc is a main initiator caspase, while strica plays a minor role that overlaps with dronc's. As for effector caspases, vCrz PCD requires both ice and dcp-1 functions, as they work cooperatively for a timely removal of the vCrz neurons. Interestingly, the activation of the Ice and Dcp-1 is not solely dependent on Dronc and Strica, implying an alternative pathway to activate the effectors. Two remaining effector caspase genes, decay and damm, found no apparent functions in the neuronal PCD, at least during early metamorphosis. Overall, our work revealed that vCrz PCD utilizes dronc, strica, dcp-1, and ice wherein the activation of Ice and Dcp-1 requires a novel pathway in addition to the initiator caspases.

Objectives. We used race-corrected data and comprehensive diagnostic codes to better compare HIV and tuberculosis (TB) mortality from 1999 to 2009 between American Indian/Alaska Natives (AI/ANs) and Whites. Methods. National Vital Statistics Surveillance System mortality data were adjusted for AI/AN racial misclassification through linkage with Indian Health Service registration records. We compared average annual 1990 to 2009 HIV and TB death rates (per 100 000 people) for AI/AN persons with those for Whites; Hispanics were excluded. Results. Although death rates from HIV in AI/AN persons were significantly lower than those in Whites from 1990 to 1998 (4.2 vs 7.0), they were significantly higher than those in Whites from 1999 to 2009 (3.6 vs 2.0). Death rates from TB in AI/AN persons were significantly higher than those in Whites, with a significant disparity during both 1990 to 1998 (3.3 vs 0.3) and 1999 to 2009 (1.5 vs 0.1). Conclusions. The decrease in death rates from HIV and TB was greater among Whites, and death rates remained significantly higher among AI/AN individuals. Public health interventions need to be prioritized to reduce the TB and HIV burden and mortality in AI/AN populations. PMID:24754664

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

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.

Identification of positional candidates for bovine placental genes responsible for early embryonic death during cloning-attempted pregnancy.

Our previous study detected 291 and 77 genes showing early embryonic death-associated elevation and reduction of expression, respectively, in the fetal placenta of the cow carrying somatic nuclear transfer-derived cloned embryo. In this study, we mapped the 10 genes showing the elevation and the 10 genes doing the reduction most significantly, using somatic cell hybrid and bovine draft genome sequence. We then compared the mapped positions for these genes with the genomic locations of bovine quantitative trait loci for still-birth and/or abortion. Among the mapped genes, peptidylglycine alpha-amidating monooxygenase (PAM), spectrin, beta, nonerythrocytic 1 (SPTBNI), and an unknown novel gene containing AU277832 expressed sequence tag were intriguing, in that the mapped positions were consistent with the genomic locations of bovine still-birth and/or abortion quantitative trait loci, and thus identified as positional candidates for bovine placental genes responsible for the early embryonic death during the pregnancy attempted by somatic nuclear transfer-derived cloning.

To address the opioid overdose epidemic in the United States, states have implemented policies to reduce inappropriate opioid prescribing. These policies could affect the coincident heroin overdose epidemic by either driving the substitution of heroin for opioids or reducing simultaneous use of both substances. We used IMS Health's National Prescription Audit and government mortality data to examine the effect of these policies on opioid prescribing and on prescription opioid and heroin overdose death rates in the United States during 2006-13. The analysis revealed that combined implementation of mandated provider review of state-run prescription drug monitoring program data and pain clinic laws reduced opioid amounts prescribed by 8 percent and prescription opioid overdose death rates by 12 percent. We also observed relatively large but statistically insignificant reductions in heroin overdose death rates after implementation of these policies. This combination of policies was effective, but broader approaches to address these coincident epidemics are needed. Project HOPE—The People-to-People Health Foundation, Inc.

Patterns of mortality rates in Darfur conflict.

Degomme, Olivier; Guha-Sapir, Debarati

2010-01-23

Several mortality estimates for the Darfur conflict have been reported since 2004, but few accounted for conflict dynamics such as changing displacement and causes of deaths. We analyse changes over time for crude and cause-specific mortality rates, and assess the effect of displacement on mortality rates. Retrospective mortality surveys were gathered from an online database. Quasi-Poisson models were used to assess mortality rates with place and period in which the survey was done, and the proportions of displaced people in the samples were the explanatory variables. Predicted mortality rates for five periods were computed and applied to population data taken from the UN's series about Darfur to obtain the number of deaths. 63 of 107 mortality surveys met all criteria for analysis. Our results show significant reductions in mortality rates from early 2004 to the end of 2008, although rates were higher during deployment of fewer humanitarian aid workers. In general, the reduction in rate was more important for violence-related than for diarrhoea-related mortality. Displacement correlated with increased rates of deaths associated with diarrhoea, but also with reduction in violent deaths. We estimated the excess number of deaths to be 298 271 (95% CI 178 258-461 520). Although violence was the main cause of death during 2004, diseases have been the cause of most deaths since 2005, with displaced populations being the most susceptible. Any reduction in humanitarian assistance could lead to worsening mortality rates, as was the case between mid 2006 and mid 2007. Copyright 2010 Elsevier Ltd. All rights reserved.

To determine whether all-cause and cardiovascular disease (CVD) death rates declined between 1997 and 2006, a period of continued advances in treatment approaches and risk factor control, among U.S. adults with and without diabetes. We compared 3-year death rates of four consecutive nationally representative samples (1997-1998, 1999-2000, 2001-2002, and 2003-2004) of U.S. adults aged 18 years and older using data from the National Health Interview Surveys linked to National Death Index. Among diabetic adults, the CVD death rate declined by 40% (95% CI 23-54) and all-cause mortality declined by 23% (10-35) between the earliest and latest samples. There was no difference in the rates of decline in mortality between diabetic men and women. The excess CVD mortality rate associated with diabetes (i.e., compared with nondiabetic adults) decreased by 60% (from 5.8 to 2.3 CVD deaths per 1,000) while the excess all-cause mortality rate declined by 44% (from 10.8 to 6.1 deaths per 1,000). Death rates among both U.S. men and women with diabetes declined substantially between 1997 and 2006, reducing the absolute difference between adults with and without diabetes. These encouraging findings, however, suggest that diabetes prevalence is likely to rise in the future if diabetes incidence is not curtailed.

Apoptosis is triggered by the activation of caspases and characterized by chromatin condensation and nuclear fragmentation (type II nuclear morphology). Necrosis is depicted by a gain in cell volume (oncosis), swelling of organelles, plasma membrane leakage, and subsequent loss of intracellular contents. Although considered as different cell death entities, there is an overlap between apoptosis and necrosis. In this sense, mounting evidence suggests that both processes can be morphological expressions of a common biochemical network known as "apoptosis-necrosis continuum." To gain insight into the events driving the apoptosis-necrosis continuum, apoptotically proficient cells were screened facing several apoptotic inducers for the absence of type II apoptotic nuclear morphologies. Chelerythrine was selected for further studies based on its cytotoxicity and the lack of apoptotic nuclear alterations. Chelerythrine triggered an early plasma membrane leakage without condensed chromatin aggregates. Ultrastructural analysis revealed that chelerythrine-mediated cytotoxicity was compatible with a necrotic-like type of cell death. Biochemically, chelerythrine induced the activation of caspases. Moreover, the inhibition of caspases prevented chelerythrine-triggered necrotic-like cell death. Compared with staurosporine, chelerythrine induced stronger caspase activation detectable at earlier times. After using a battery of chemicals, we found that high concentrations of thiolic antioxidants fully prevented chelerythrine-driven caspase activation and necrotic-like cell death. Lower amounts of thiolic antioxidants partially prevented chelerythrine-mediated cytotoxicity and allowed cells to display type II apoptotic nuclear morphology correlating with a delay in caspase-3 activation. Altogether, these data support that an early and pronounced activation of caspases can drive cells to undergo a form of necrotic-like regulated cell death. © 2015 by The American Society for

Background Motor vehicle crashes are a leading cause of death among children in the United States. Age- and size-appropriate child restraint use is the most effective method for reducing these deaths. Methods CDC analyzed 2002–2011 data from the Fatality Analysis Reporting System to determine the number and rate of motor-vehicle occupant deaths, and the proportion of unrestrained child deaths among children aged <1 year, 1–3 years, 4–7 years, 8–12 years, and for all children aged 0–12 years. Age group–specific death rates and proportions of unrestrained child motor vehicle deaths for 2009–2010 were further stratified by race/ethnicity. Results Motor vehicle occupant death rates for children declined significantly from 2002 to 2011. However, one third (33%) of children who died in 2011 were unrestrained. Compared with white children for 2009–2010, black children had significantly higher death rates, and black and Hispanic children both had significantly higher proportions of unrestrained child deaths. Conclusions Motor vehicle occupant deaths among children in the United States have declined in the past decade, but more deaths could be prevented if restraints were always used. Implications for Public Health Effective interventions, including child passenger restraint laws (with child safety seat/booster seat coverage through at least age 8 years) and child safety seat distribution plus education programs, can increase restraint use and reduce child motor vehicle deaths.

Cell death and morphogenesis during early mouse development: are they interconnected?

PubMed

Bedzhov, Ivan; Zernicka-Goetz, Magdalena

Shortly after implantation the embryonic lineage transforms from a coherent ball of cells into polarized cup shaped epithelium. Recently we elucidated a previously unknown apoptosis-independent morphogenic event that reorganizes the pluripotent lineage. Polarization cues from the surrounding basement membrane rearrange the epiblast into a polarized rosette-like structure, where subsequently a central lumen is established. Thus, we provided a new model revising the current concept of apoptosis-dependent epiblast morphogenesis. Cell death however has to be tightly regulated during embryogenesis to ensure developmental success. Here, we follow the stages of early mouse development and take a glimpse at the critical signaling and morphogenic events that determine cells destiny and reshape the embryonic lineage. © 2015 The Authors.

Primary adrenal insufficiency (Addison's disease) is a rare autoimmune disease. Until recently, life expectancy in Addison's disease patients was considered normal. To determine the mortality rate in Addison's disease patients. i) Patients registered with Addison's disease in Norway during 1943-2005 were identified through search in hospital diagnosis registries. Scrutiny of the medical records provided diagnostic accuracy and age at diagnosis. ii) The patients who had died were identified from the National Directory of Residents. iii) Background mortality data were obtained from Statistics Norway, and standard mortality rate (SMR) calculated. iv) Death diagnoses were obtained from the Norwegian Death Cause Registry. Totally 811 patients with Addison's disease were identified, of whom 147 were deceased. Overall SMR was 1.15 (95% confidence intervals (CI) 0.96-1.35), similar in females (1.18 (0.92-1.44)) and males (1.10 (0.80-1.39)). Patients diagnosed before the age of 40 had significantly elevated SMR at 1.50 (95% CI 1.09-2.01), most pronounced in males (2.03 (1.19-2.86)). Acute adrenal failure was a major cause of death; infection and sudden death were more common than in the general population. The mean ages at death for females (75.7 years) and males (64.8 years) were 3.2 and 11.2 years less than the estimated life expectancy. Addison's disease is still a potentially lethal condition, with excess mortality in acute adrenal failure, infection, and sudden death in patients diagnosed at young age. Otherwise, the prognosis is excellent for patients with Addison's disease.

Death rates for acquired hypothyroidism and thyrotoxicosis in English populations (1979-2010): comparison of underlying cause and all certified causes.

Overt hypothyroidism and thyrotoxicosis have widespread systemic effects and are associated with increased mortality. Most death certificates that include them do not have the thyroid disease coded as the underlying cause of death. To describe regional (1979-2010) and national (1995-2010) trends in mortality rates for acquired hypothyroidism and thyrotoxicosis, analysing all certified causes of death (termed 'mentions') and not just the underlying cause. Analysis of death registration data. Analysis of data for the Oxford region (mentions available from 1979) and English national data (mentions available from 1995). The data were grouped in periods defined by different national rules for selecting the underlying cause of death (1979-83, 1984-92, 1993-2000 and 2001-10) and were also analysed as single calendar years. Mentions mortality for acquired hypothyroidism in the Oxford region declined significantly from 1979 to 2010: the average annual percentage change (AAPC) was -2.6% (95% confidence intervals -3.5, -1.8). Most of the decrease occurred during the 1980s. The AAPC in rates for later years in England (1995-2010) was non-significant at 0.2% (-0.7, 1.0). Mortality rates for thyrotoxicosis decreased significantly: the AAPC was -2.8% (-4.1, -1.5) in the Oxford region and -3.8% (-4.7, -3.0) in England. In England, between 2001 and 2010, hypothyroidism or thyrotoxicosis was coded as the underlying cause of death on, respectively, 17 and 24% of death certificates that included them. Mortality rates for hypothyroidism and thyrotoxicosis have fallen substantially. The fall is probably wholly or mainly a result of improved care.

Death during an operation represents a severe event for physicians and family of the deceased. A further difficulty arises when certifying the cause and manner of death because medical staff are often afraid that they will incriminate themselves when declaring an unnatural death or an unclear manner of death but are also afraid to issue a false statement by declaring a natural death. In such cases of mors in tabula it is recommended to declare an unclear manner of death because this leads to police investigations and in the majority of the cases to exoneration of the medical staff.

Control of transportation death rates by varying road microstructure using segmental pavers

DOE Office of Scientific and Technical Information (OSTI.GOV)

Halperin, K.

It is known that redesign of older roads to limit the mean and top speeds along them can prevent crashes and save lives. In many parts of the world, a standard part of this redesign for lower speeds consists of repaving with segmental pavers, particularly concrete pavers. Yet no controlled experimentation has been done to establish the relationship between paver texture, speed and crash, injury and mortality rates. Two possible experiments are proposed. It is further proposed that governments in English-speaking North America cannot await the results of such experiments to begin redesigning older roads to lower their death rates.

To determine the influence of preexisting heart, liver, kidney, cancer, stroke, and mental health problems and examine the influence of low socioeconomic status on mortality after discharge from acute care facilities for individuals with traumatic brain injury. Population-based retrospective cohort study of 33695 persons discharged from acute care hospital with traumatic brain injury in South Carolina, 1999-2010. Days elapsing from the dates of injury to death established the survival time (T). Data were censored at the 145th month. Multivariable Cox regression was used to examine the independent effect of the variables on death. Age-adjusted cumulative probability of death for each chronic disease of interest was plotted. By the 70th month of follow-up, rate of death was accelerated from 10-fold for heart diseases to 2.5-fold for mental health problems. Adjusted hazard ratios for diseases of the heart (2.13), liver-renal (3.25), cancer (2.64), neurological diseases and stroke (2.07), diabetes (1.89), hypertension (1.43), and mental health problems (1.59) were highly significant (each with P < .001). Compared with persons with private insurance, the hazard ratio was significantly elevated with Medicaid (1.67), Medicare (1.54), and uninsured (1.27) (each with P < .001). Specific chronic diseases strongly influenced postdischarge mortality after traumatic brain injury. Low socioeconomic status as measured by the type of insurance elevated the risk of death.

Compare age-adjusted rates of death due to liver, kidney, and heart diseases during 2009-2011 among US residents diagnosed with HIV infection with those in the general population. Numerators were numbers of records of multiple-cause mortality data from the national vital statistics system with an ICD-10 code for the disease of interest (any mention, not necessarily the underlying cause), divided into those 1) with and 2) without an additional code for HIV infection. Denominators were 1) estimates of persons living with diagnosed HIV infection from national HIV surveillance system data and 2) general population estimates from the US Census Bureau. We compared age-adjusted rates overall (unstratified by sex, race/ethnicity, or region of residence) and stratified by demographic group. Overall, compared with the general population, persons diagnosed with HIV infection had higher age-adjusted rates of death reported with hepatitis B (rate ratio [RR]=42.6; 95% CI: 34.7-50.7), hepatitis C (RR=19.4; 95% CI: 18.1-20.8), liver disease excluding hepatitis B or C (RR=2.1; 95% CI: 1.8-2.3), kidney disease (RR=2.4; 95% CI: 2.2-2.6), and cardiomyopathy (RR=1.9; 95% CI: 1.6-2.3), but lower rates of death reported with ischemic heart disease (RR=0.6; 95% CI: 0.6-0.7) and heart failure (RR=0.8; 95% CI: 0.6-0.9). However, the differences in rates of death reported with the heart diseases were insignificant in some demographic groups. Persons with HIV infection have a higher risk of death with liver and kidney diseases reported as causes than the general population.

Sudden cardiac death (SCD) represents about 25% of deaths in clinical cardiology. The identification of risk factors for SCD is the philosopher's stone of cardiology and the identification of non-invasive markers of risk of SCD remains one of the most important goals for the scientific community.The aim of this review is to analyze the state of the art around the heart rate variability (HRV) as a predictor factor for SCD.HRV is probably the most analyzed index in cardiovascular risk stratification technical literature, therefore an important number of models and methods have been developed.Nowadays, low HRV has been shown to be independently predictive of increased mortality in post- myocardial infarction patients, heart failure patients, in contrast with the data of the general population.Contrariwise, the relationship between HRV and SCD has received scarce attention in low-risk cohorts. Furthermore, in general population the attributable risk is modest and the cost/benefit ratio is not always convenient.The HRV evaluation could become an important tool for health status in risks population, even though the use of HRV alone for risk stratification of SCD is limited and further studies are needed.

To determine population-based neonatal mortality rates in low- and middle-income countries and to examine gestational age, birth weight, and timing of death to assess the potentially preventable neonatal deaths. A prospective observational study was conducted in communities in five low-income countries (Kenya, Zambia, Guatemala, India, and Pakistan) and one middle-income country (Argentina). Over a 2-year period, all pregnant women in the study communities were enrolled by trained study staff and their infants followed to 28 days of age. Between October 2009 and March 2011, 153,728 babies were delivered and followed through day 28. Neonatal death rates ranged from 41 per 1000 births in Pakistan to 8 per 1000 in Argentina; 54% of the neonatal deaths were >37 weeks and 46% weighed 2500 g or more. Half the deaths occurred within 24 hours of delivery. In our population-based low- and middle-income country registries, the majority of neonatal deaths occurred in babies >37 weeks' gestation and almost half weighed at least 2500 g. Most deaths occurred shortly after birth. With access to better medical care and hospitalization, especially in the intrapartum and early neonatal period, many of these neonatal deaths might be prevented.

It is currently unclear if carotid artery stenting (CAS) is as safe as carotid endarterectomy (CEA) for patients with significant asymptomatic stenosis. The aim of our study was to perform a systematic review and meta-analysis of trials comparing CAS with CEA. On March 17, 2017, a search for randomized controlled trials was performed in MEDLINE and Scopus databases with no time limits. We performed meta-analyses with Peto odds ratios (ORs) and 95% confidence intervals (CIs). Quality of evidence was assessed with the Grading of Recommendations Assessment, Development, and Evaluation method. The primary safety and efficacy outcome measures were stroke or death rate at 30 days and ipsilateral stroke at 1 year (including ipsilateral stroke and death rate at 30 days), respectively. Perioperative stroke, ipsilateral stroke, myocardial infarction (MI), and cranial nerve injury (CNI) were all secondary outcome measures. The systematic review of the literature identified nine randomized controlled trials reporting on 3709 patients allocated into CEA (n = 1479) or CAS (n = 2230). Stroke or death rate at 30 days was significantly higher for CAS (64/2176 [2.94%]) compared with CEA (27/1431 [1.89%]; OR, 1.57; 95% CI, 1.01-2.44; P = .044), with low level of heterogeneity beyond chance (I 2  = 0%). Also, stroke rate at 30 days was significantly higher for CAS (63/2176 [2.90%]) than for CEA (26/1431 [1.82%]; OR, 1.63; 95% CI, 1.04-2.54; P = .032; I 2  = 0%). MI at 30 days was nonsignificantly lower for CAS (12/1815 [0.66%]) compared with CEA (16/1070 [1.50%]; OR, 0.53; 95% CI, 0.24-1.14; P = .105; I 2  = 0%); however, CNI at 30 days was significantly lower for CAS (2/1794 [0.11%]) than for CEA (33/1061 [3.21%]; OR, 0.13; 95% CI, 0.07-0.26; P < .00001; I 2  = 0%). Regarding the long-term outcome of stroke or death rate at 30 days plus ipsilateral stroke during follow-up, this was significantly higher for CAS (79/2173 [3.64%]) than for CEA (35/1430 [2.45%]; OR, 1

Unintentional fall-related traumatic brain injury (TBI) death rate is high in older adults in the United States, but little is known regarding trends of these death rates. We sought to examine unintentional fall-related TBI death rates by age and sex in older adults from 1980 through 2010 in the United States. We used multiple-cause mortality data from 1980 through 2010 (31 years of data) to identify fall-related TBI deaths. Using a joinpoint regression program, we determined the joinpoints (years at which trends change significantly) and annual percentage changes (APCs) in mortality trends. The fall-related TBI death rates (deaths per 100,000 population) in older adults ages 65-74, 75-84, and 85 years and above were 2.7, 9.2, and 21.5 for females and 8.5, 18.2, and 40.8 for males, respectively, in 1980. The rate was about the same in 1992, yet increased markedly to 5.9, 23.4, and 68.9 for females and 11.6, 41.2, and 112.4 for males, respectively, in 2010. For males all 65 years years of age and above, we found the first joinpoint in 1992, when the APC for 1980 through 1992, -0.8%, changed to 6.2% for 1992-2005. The second joinpoint occurred in 2005, when the APC decreased to 3.7% for 2005-2010. For all females 65 years of age and above, the first joinpoint was in 1993 when the APC for 1980 through 1993, -0.2%, changed to 7.6% from 1993 to 2005. The second joinpoint occurred in 2005 when the APC decreased to 3.8% for 2005-2010. This descriptive epidemiological study suggests increasing fall-related TBI death rates from 1992 to 2005 and then a slowdown of increasing trends between 2005 and 2010. Continued monitoring of fall-related TBI death rate trends is needed to determine the burden of this public health problem among older adults in the United States.

Interpreting the gamma statistic in phylogenetic diversification rate studies: a rate decrease does not necessarily indicate an early burst.

PubMed

Fordyce, James A

2010-07-23

Phylogenetic hypotheses are increasingly being used to elucidate historical patterns of diversification rate-variation. Hypothesis testing is often conducted by comparing the observed vector of branching times to a null, pure-birth expectation. A popular method for inferring a decrease in speciation rate, which might suggest an early burst of diversification followed by a decrease in diversification rate is the gamma statistic. Using simulations under varying conditions, I examine the sensitivity of gamma to the distribution of the most recent branching times. Using an exploratory data analysis tool for lineages through time plots, tree deviation, I identified trees with a significant gamma statistic that do not appear to have the characteristic early accumulation of lineages consistent with an early, rapid rate of cladogenesis. I further investigated the sensitivity of the gamma statistic to recent diversification by examining the consequences of failing to simulate the full time interval following the most recent cladogenic event. The power of gamma to detect rate decrease at varying times was assessed for simulated trees with an initial high rate of diversification followed by a relatively low rate. The gamma statistic is extraordinarily sensitive to recent diversification rates, and does not necessarily detect early bursts of diversification. This was true for trees of various sizes and completeness of taxon sampling. The gamma statistic had greater power to detect recent diversification rate decreases compared to early bursts of diversification. Caution should be exercised when interpreting the gamma statistic as an indication of early, rapid diversification.

Life years saved, standardised mortality rates and causes of death after hospital discharge in out-of-hospital cardiac arrest survivors.

Out-of-hospital cardiac arrest (OHCA) accounts for many unexpected deaths in Europe and the survival rates in different regions vary considerably. We have previously reported excellent survival to discharge rates in the Stavanger region. We now describe the long-term outcome of OHCA victims in our region. In this retrospective observational study, we followed all OHCA hospital discharge survivors between 01.07.2002 and 30.06.2011 (n=213) for a minimum of 1 year and up to 10 years. Based on the national death statistics stratified for gender and age, we could calculate the potential life years saved, standardised mortality rates (SMR) and delineate the causes of death after hospital discharge. Of the 213 patients who were discharged from the hospital, 91% had a cardiac origin of their OHCA. The mean potential life years saved per patient was 22.8 years. The observed five-year survival rate was 76%. The overall SMR in our study cohort was 2.3 when compared to the age- and gender-matched population. Cardiac disease was a prominent cause of late deaths, with the specific SMR for cardiac disease-related deaths being as high as 42 in males and 140 in females. Resuscitation of OHCA victims lead to a significant long-term benefit with respect to life years saved. Cardiac disease was the main cause of death after hospital discharge. More studies are needed to identify the potential of therapeutic interventions and rehabilitation efforts that may further enhance the long-term outcomes in OHCA hospital discharge survivors.

2017-04-01

Although the Organ Procurement and Transplantation Network (OPTN) database contains a rich set of data on United States transplant recipients, follow-up data may be incomplete. It was of interest to determine if augmenting OPTN data with external death data altered patient survival estimates. Solitary kidney, liver, heart, and lung transplants performed between January 1, 2011, and January 31, 2013, were queried from the OPTN database. Unadjusted Kaplan-Meier 3-year patient survival rates were computed using 4 nonmutually exclusive augmented datasets: OPTN only, OPTN + verified external deaths, OPTN + verified + unverified external deaths (OPTN + all), and an additional source extending recipient survival time if no death was found in OPTN + all (OPTN + all [Assumed Alive]). Pairwise comparisons were made using unadjusted Cox Proportional Hazards analyses applying Bonferroni adjustments. Although differences in patient survival rates across data sources were small (≤1 percentage point), OPTN only data often yielded slightly higher patient survival rates than sources including external death data. No significant differences were found, including comparing OPTN + verified (hazard ratio [HR], 1.05; 95% confidence interval [95% CI], 1.00-1.10); P = 0.0356), OPTN + all (HR, 1.06; 95% CI, 1.01-1.11; P = 0.0243), and OPTN + all (Assumed Alive) (HR, 1.00; 95% CI, 0.96-1.05; P = 0.8587) versus OPTN only, or OPTN + verified (HR, 1.05; 95% CI, 1.00-1.10; P = 0.0511), and OPTN + all (HR, 1.05; 95% CI, 1.00-1.10; P = 0.0353) versus OPTN + all (Assumed Alive). Patient survival rates varied minimally with augmented data sources, although using external death data without extending the survival time of recipients not identified in these sources results in a biased estimate. It remains important for transplant centers to maintain contact with transplant recipients and obtain necessary follow-up information, because this information can improve the transplantation process for

Objectives To monitor the early effect of a national population screening programme for abdominal aortic aneurysm in 65-year-old men. Setting The study used national statistics for death rates from abdominal aortic aneurysm (Office of National Statistics) and hospital admission data in England (Hospital Episode Statistics). Methods Information concerning deaths from abdominal aortic aneurysm (ruptured and non-ruptured) (1999-2014) and hospital admissions for ruptured abdominal aortic aneurysm (2000-2015) was examined. Results The absolute number of deaths from abdominal aortic aneurysm in men and women aged 65 and over has decreased by around 30% from 2001 to 2014, but as the population has increased, the relative reduction was 45.6% and 40.0%, respectively. Some 65% of all abdominal aortic aneurysm deaths are in men aged over 65; women aged 65 and over account for around 31%. Deaths from ruptured abdominal aortic aneurysm in men aged 60-74 (the screened group) appear to be declining at the same rate as in men aged 75 and over. The relative decline in admissions to hospital with ruptured abdominal aortic aneurysm may be greater in men and women aged 60-74 (which contains the screened group of men), than those older, giving the first possible evidence that abdominal aortic aneurysm screening is having an effect. Conclusion The death rate from abdominal aortic aneurysm is declining rapidly in England. There is the first evidence that screening may be contributing to this reduction.

The purpose of this study was to determine whether the presence of gynecologic malignancies predicts the likelihood of a tertiary palliative care unit hospital admission. In this study, patients admitted to a specialized tertiary palliative care unit (TPCU) with gynecologic malignancies were compared to national and provincial death rates to determine if gynecologic malignancy predicts admission, and subsequent death, in a TPCU. Eighty-two gynecologic cancer patients were admitted to our TPCU over the 5- year study period. Out of all cancer deaths in the TPCU, death from ovarian cancer was 3.7% compared with 2.4% (p = 0.0068) of all cancer deaths in Manitoba and 2.3% (p = 0.0043) of all cancer deaths in Canada. Cervical cancer accounted for 1.7% of all our patients deaths compared with 0.7% (p = 0.0001) provincially and 0.6% (p = 0.0001) nationally. Uterine cancer deaths were not significantly different from the provincial and national death rates, whereas vulvar and fallopian cancers were too rare to allow for statistical analysis. Gynecologic cancers may be predictive of admission to a palliative care unit.

Effect of marital status on death rates. Part 1: High accuracy exploration of the Farr-Bertillon effect

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.

Canadian Military Nurse Deaths in the First World War.

PubMed

Dodd, Dianne

2017-01-01

This paper examines the lives of sixty-one Canadian Nursing Sisters who served during the First World War, and whose deaths were attributed, more or less equally, to three categories: general illness, Spanish Influenza, and killed in action. The response by Canadian Army Medical Corps (CAMC) physicians to the loss of these early female officers who were, in fact, Canada's first female war casualties, suggests a gendered construction of illness at work in the CAMC. While nurses tried to prove themselves good soldiers, military physicians were quick to attribute their illnesses and deaths to horrific war conditions deemed unsuitable for women. This gendered response is particularly evident in how CAMC physicians invoked a causal role for neurasthenia or shell shock for the nurses' poor health. The health profile of these women also suggests that some of these deaths might have occurred had these women stayed in Canada, and it encourages future comparative research into death rates among physicians and orderlies.

Aggressive management of patients prior to and after determination of death by neurologic criteria (DNC) is necessary to optimize organ recovery, transplantation, and increase the number of organs transplanted per donor (OTPD). The effects of time management are understudied but potentially pivotal component. The objective of this study was to analyze specific time points (time to DNC, time to procurement) and the time intervals between them to better characterize the optimal timeline of organ donation. Using data over a 5-year time period (2011-2015) from the largest US OPO, all patients with catastrophic brain injury and donated transplantable organs were retrospectively reviewed. Active smokers were excluded. Maximum donor potential was seven organs (heart, lungs [2], kidneys [2], liver, and pancreas). Time from admission to declaration of DNC and donation was calculated. Mean time points stratified by specific organ procurement rates and overall OTPD were compared using unpaired t-test. Of 1719 Declaration of Death by Neurologic Criteria organ donors, 381 were secondary to head trauma. Smokers and organs recovered but not transplanted were excluded leaving 297 patients. Males comprised 78.8%, the mean age was 36.0 (±16.8) years, and 87.6% were treated at a trauma center. Higher donor potential (>4 OTPD) was associated with shorter average times from admission to brain death; 66.6 versus 82.2 hours, P = 0.04. Lung donors were also associated with shorter average times from admission to brain death; 61.6 versus 83.6 hours, P = 0.004. The time interval from DNC to donation varied minimally among groups and did not affect donation rates. A shorter time interval between admission and declaration of DNC was associated with increased OTPD, especially lungs. Further research to identify what role timing plays in the management of the potential organ donor and how that relates to donor management goals is needed. Copyright © 2017 Elsevier Inc. All rights

Refusal to consent to organ donation is an important cause of the persisting gap between the number of potential organ donors and effectuated donors. In the Netherlands, organ donors include both uncontrolled donors: donors who die unexpectedly after cardiac death (DCD), after failed resuscitation and donors in whom death can be expected and donors after brain death, and controlled DCD donors: those who die after the withdrawal of treatment. Different donor type implies a different setting in which relatives are requested to consent to organ donation. It is unknown whether the setting influences the eventual decision for donation or not. Therefore, we compared the consent rate in potential donors who died unexpectedly (UD group) and in whom death was expected. A total of 523 potential organ donors between 2003 and 2011 in the 715-bed Maastricht University Medical Centre, the Netherlands were included. Both the patients' registration in the national donor register (DR) and the relatives' refusal rate in the two groups were retrospectively assessed using data from the donation application database. There were 109 unexpected and 414 expected potential donors The potential donors in the UD group were younger (mean age 52 versus 55 years, P = 0.032) and more often male (68 versus 52%, P = 0.003). There were no significant differences in registration in the DR between the groups. The relatives' consent rate in non-registered potential donors, or those who mandated the relatives for that decision, was higher in the UD group (53 versus 29%, P < 0.001). Less than 50% of the potential donors were registered in the national DR. Therefore, the relatives have an important role in the choice for organ donation. The relatives of potential donors who died unexpectedly consented more often to donation than those in whom death was expected.

Abstract Objective To carry out a descriptive analysis of mesothelioma deaths reported worldwide between 1994 and 2008. Methods We extracted data on mesothelioma deaths reported to the World Health Organization mortality database since 1994, when the disease was first recorded. We also sought information from other English-language sources. Crude and age-adjusted mortality rates were calculated and mortality trends were assessed from the annual percentage change in the age-adjusted mortality rate. Findings In total, 92 253 mesothelioma deaths were reported by 83 countries. Crude and age-adjusted mortality rates were 6.2 and 4.9 per million population, respectively. The age-adjusted mortality rate increased by 5.37% per year and consequently more than doubled during the study period. The mean age at death was 70 years and the male-to-female ratio was 3.6:1. The disease distribution by anatomical site was: pleura, 41.3%; peritoneum, 4.5%; pericardium, 0.3%; and unspecified sites, 43.1%. The geographical distribution of deaths was skewed towards high-income countries: the United States of America reported the highest number, while over 50% of all deaths occurred in Europe. In contrast, less than 12% occurred in middle- and low-income countries. The overall trend in the age-adjusted mortality rate was increasing in Europe and Japan but decreasing in the United States. Conclusion The number of mesothelioma deaths reported and the number of countries reporting deaths increased during the study period, probably due to better disease recognition and an increase in incidence. The different time trends observed between countries may be an early indication that the disease burden is slowly shifting towards those that have used asbestos more recently. PMID:22084509

Despite substantial declines since the 1960's, heart disease remains the leading cause of death in the United States (US) and geographic disparities in heart disease mortality have grown. State-level socioeconomic factors might be important contributors to geographic differences in heart disease mortality. This study examined the association between state-level minimum wage increases above the federal minimum wage and heart disease death rates from 1980 to 2015 among 'working age' individuals aged 35-64 years in the US. Annual, inflation-adjusted state and federal minimum wage data were extracted from legal databases and annual state-level heart disease death rates were obtained from CDC Wonder. Although most minimum wage and health studies to date use conventional regression models, we employed marginal structural models to account for possible time-varying confounding. Quasi-experimental, marginal structural models accounting for state, year, and state × year fixed effects estimated the association between increases in the state-level minimum wage above the federal minimum wage and heart disease death rates. In models of 'working age' adults (35-64 years old), a $1 increase in the state-level minimum wage above the federal minimum wage was on average associated with ~6 fewer heart disease deaths per 100,000 (95% CI: -10.4, -1.99), or a state-level heart disease death rate that was 3.5% lower per year. In contrast, for older adults (65+ years old) a $1 increase was on average associated with a 1.1% lower state-level heart disease death rate per year (b = -28.9 per 100,000, 95% CI: -71.1, 13.3).

BACKGROUND: Delinquent youth are at risk for early violent death after release from detention. However, few studies have examined risk factors for mortality. Previous investigations studied only serious offenders (a fraction of the juvenile justice population) and provided little data on females. METHODS: The Northwestern Juvenile Project is a prospective longitudinal study of health needs and outcomes of a stratified random sample of 1829 youth (657 females, 1172 males; 524 Hispanic, 1005 African American, 296 non-Hispanic white, 4 other race/ethnicity) detained between 1995 and 1998. Data on risk factors were drawn from interviews; death records were obtained up to 16 years after detention. We compared all-cause mortality rates and causes of death with those of the general population. Survival analyses were used to examine risk factors for mortality after youth leave detention. RESULTS: Delinquent youth have higher mortality rates than the general population to age 29 years (P < .05), irrespective of gender or race/ethnicity. Females died at nearly 5 times the general population rate (P < .05); Hispanic males and females died at 5 and 9 times the general population rates, respectively (P < .05). Compared with the general population, significantly more delinquent youth died of homicide and its subcategory, homicide by firearm (P < .05). Among delinquent youth, racial/ethnic minorities were at increased risk of homicide compared with non-Hispanic whites (P < .05). Significant risk factors for external-cause mortality and homicide included drug dealing (up to 9 years later), alcohol use disorder, and gang membership (up to a decade later). CONCLUSIONS: Delinquent youth are an identifiable target population to reduce disparities in early violent death. PMID:24936005

Background Rates of death from cardiovascular and cerebrovascular diseases have been steadily declining over the past few decades. Whether such declines are occurring to a similar degree for common disorders such as acute myocardial infarction, heart failure and stroke is uncertain. We examined recent national trends in mortality and rates of hospital admission for these 3 conditions. Methods We analyzed mortality data from Statistic Canada’s Canadian Mortality Database and data on hospital admissions from the Canadian Institute for Health Information’s Hospital Morbidity Database for the period 1994–2004. We determined age- and sex-standardized rates of death and hospital admissions per 100 000 population aged 20 years and over as well as in-hospital case-fatality rates. Results The overall age- and sex-standardized rate of death from cardiovascular disease in Canada declined 30.0%, from 360.6 per 100 000 in 1994 to 252.5 per 100 000 in 2004. During the same period, the rate fell 38.1% for acute myocardial infarction, 23.5% for heart failure and 28.2% for stroke, with improvements observed across most age and sex groups. The age- and sex-standardized rate of hospital admissions decreased 27.6% for stroke and 27.2% for heart failure. The rate for acute myocardial infarction fell only 9.2%. In contrast, the relative decline in the inhospital case-fatality rate was greatest for acute myocardial infarction (33.1%; p < 0.001). Much smaller relative improvements in case-fatality rates were noted for heart failure (8.1%) and stroke (8.9%). Interpretation The rates of death and hospital admissions for acute myocardial infarction, heart failure and stroke in Canada changed at different rates over the 10-year study period. Awareness of these trends may guide future efforts for health promotion and health care planning and help to determine priorities for research and treatment. PMID:19546444

Racial bias is associated with ingroup death rate for Blacks and Whites: Insights from Project Implicit.

PubMed

Leitner, Jordan B; Hehman, Eric; Ayduk, Ozlem; Mendoza-Denton, Rodolfo

2016-10-20

Research suggests that, among Whites, racial bias predicts negative ingroup health outcomes. However, little is known about whether racial bias predicts ingroup health outcomes among minority populations. The aim of the current research was to understand whether racial bias predicts negative ingroup health outcomes for Blacks. We compiled racial bias responses from 250,665 Blacks and 1,391,632 Whites to generate county-level estimates of Blacks' and Whites' implicit and explicit biases towards each other. We then examined the degree to which these biases predicted ingroup death rate from circulatory-related diseases. In counties where Blacks harbored more implicit bias towards Whites, Blacks died at a higher rate. Additionally, consistent with previous research, in counties where Whites harbored more explicit bias towards Blacks, Whites died at a higher rate. These links between racial bias and ingroup death rate were independent of county-level socio-demographic characteristics, and racial biases from the outgroup in the same county. Findings indicate that racial bias is related to negative ingroup health outcomes for both Blacks and Whites, though this relationship is driven by implicit bias for Blacks, and explicit bias for Whites.

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. 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. 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. 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 concerning general populations, resting heart rate was not associated with sudden

In light of the large number of detainees who continue to be taken and held in US custody in settings with limited judicial or public oversight, deaths of detainees warrant scrutiny. We have undertaken the task of reviewing all known detainee deaths between 2002 and early 2005 based on reports available in the public domain. Using documents obtained from the Department of Defense through a Freedom of Information Act request, combined with a review of anecdotal published press accounts, 112 cases of death of detainees in United States custody (105 in Iraq, 7 in Afghanistan) during the period from 2002 to early 2005 were identified. Homicide accounted for the largest number of deaths (43) followed by enemy mortar attacks against the detention facility (36). Deaths attributed to natural causes numbered 20. Nine were listed as unknown cause of death, and 4 were reported as accidental or natural. A clustering of 8 deaths ascribed to natural causes in Iraq in August 2003 raises questions about the adequacy and availability of medical care, as well as other conditions of confinement that may have had an impact on the mortality rate.

Donation after circulatory death (DCD) liver transplantation (LT) reportedly yields inferior survival and increased complication rates compared with donation after brain death (DBD). We compare 100 consecutive DCD LT using a protocol that includes thrombolytic therapy (late DCD group) to an historical DCD group (early DCD group n = 38) and a cohort of DBD LT recipients (DBD group n = 435). Late DCD LT recipients had better 1- and 3-year graft survival rates than early DCD LT recipients (92% vs. 76.3%, p = 0.03 and 91.4% vs. 73.7%, p = 0.01). Late DCD graft survival rates were comparable to those of the DBD group (92% vs. 93.3%, p = 0.24 and 91.4% vs. 88.2%, p = 0.62). Re-transplantation occurred in 18.4% versus 1% for the early and late DCD groups, respectively (p = 0.001). Patient survival was similar in all three groups. Ischemic-type biliary lesions (ITBL) occurred in 5%, 3%, and 0.2% for early DCD, late DCD, and DBD groups, respectively, but unlike in the early DCD group, in the late DCD group ITBL was endoscopically managed and resolved in each case. Using a protocol that includes a thrombolytic therapy, DCD LT yielded patient and graft survival rates comparable to DBD LT. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

Recently, French policymakers have tried to improve care at the end-of-life, by improving access to community-based palliative care, particularly for patients with cancer and neurological diseases. If effective, these efforts should reduce the proportion of such patients who die in the hospital. In light of these policies, we sought to determine the effectiveness of these efforts on reducing inpatient deaths by conducting a retrospective, observational analysis of patients aged 65 and older who were admitted to hospitals in France between 2010 and 2013 for 1 of 3 non-surgical conditions. We calculated department-specific age- and sex-adjusted inpatient death rates for 3 types of nonsurgical admissions and modeled expected number of inpatient deaths had their rates for patients with cancer or neurological disease tracked those of patients with non-cancer non-neurological diseases. We found that patients admitted with a cancer diagnosis experienced 20,394 (13.0%) fewer inpatient deaths that expected had non-surgical cancer diagnosis admission rates tracked those of nonsurgical non-cancer and non-neurological admission rates; patients admitted with a primary neurological disease diagnosis experienced 513 (4.5%) fewer inpatient deaths than expected. During the study period, observed-to-expected inpatient deaths fell more dramatically and consistently for patients admitted with cancer diagnoses than for those admitted with neurological diseases. Observed-to-expected ratios fell least in departments that were on the periphery of the French mainland. Our findings suggest that, in France, efforts to reduce inpatient death rates among patients with cancer or neurological disease diagnoses appear to be effective. However, their effectiveness varies geographically, suggesting that targeted efforts to improve lower performing departments may generate substantial performance improvements.

Background In Brazil, lethality from visceral leishmaniasis (VL) is high and few studies have addressed prognostic factors. This historical cohort study was designed to investigate the prognostic factors for death from VL in Belo Horizonte (Brazil). Methodology The analysis was based on data of the Reportable Disease Information System-SINAN (Brazilian Ministry of Health) relating to the clinical manifestations of the disease. During the study period (2002–2009), the SINAN changed platform from a Windows to a Net-version that differed with respect to some of the parameters collected. Multivariate logistic regression models were performed to identify variables associated with death from VL, and these were included in prognostic score. Principal Findings Model 1 (period 2002–2009; 111 deaths from VL and 777 cured patients) included the variables present in both SINAN versions, whereas Model 2 (period 2007–2009; 49 deaths from VL and 327 cured patients) included variables common to both SINAN versions plus the additional variables included in the Net version. In Model 1, the variables significantly associated with a greater risk of death from VL were weakness (OR 2.9; 95%CI 1.3–6.4), Leishmania-HIV co-infection (OR 2.4; 95%CI 1.2–4.8) and age ≥60 years (OR 2.5; 95%CI 1.5–4.3). In Model 2, the variables were bleeding (OR 3.5; 95%CI 1.2–10.3), other associated infections (OR 3.2; 95%CI 1.3–7.8), jaundice (OR 10.1; 95%CI 3.7–27.2) and age ≥60 years (OR 3.1; 95%CI 1.4–7.1). The prognosis score was developed using the variables associated with death from VL of the latest version of the SINAN (Model 2). The predictive performance of which was evaluated by sensitivity (71.4%), specificity (73.7%), positive and negative predictive values (28.9% and 94.5%) and area under the receiver operating characteristic curve (75.6%). Conclusions Knowledge regarding the factors associated with death from VL may improve clinical management of patients and contribute

In 2013, more than 57,000 persons died in the United States as a result of violence-related injuries. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) regarding violent deaths from 17 U.S. states for 2013. Results are reported by sex, age group, race/ethnicity, marital status, location of injury, method of injury, circumstances of injury, and other selected characteristics. 2013. NVDRS collects data from participating states regarding violent deaths obtained from death certificates, coroner/medical examiner reports, law enforcement reports, and secondary sources (e.g., child fatality review team data, supplemental homicide reports, hospital data, and crime laboratory data). This report includes data from 17 states that collected statewide data for 2013 (Alaska, Colorado, Georgia, Kentucky, Maryland, Massachusetts, North Carolina, New Jersey, New Mexico, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, Utah, Virginia, and Wisconsin). NVDRS collates documents for each death and links deaths that are related (e.g., multiple homicides, a homicide followed by a suicide, or multiple suicides) from a single incident. For 2013, a total of 18,765 fatal incidents involving 19,251 deaths were captured by NVDRS in the 17 states included in this report. The majority (66.2%) of deaths were suicides, followed by homicides (23.2%), deaths of undetermined intent (8.8%), deaths involving legal intervention (1.2%) (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force, excluding legal executions), and unintentional firearm deaths (<1%). (The term legal intervention is a classification incorporated into the International Classification of Diseases, Tenth Revision [ICD-10] and does not denote the lawfulness or legality of the circumstances surrounding a death caused by law enforcement.) Suicides occurred at higher rates among males, non-Hispanic whites, American Indian/Alaska Natives, persons aged 45

To evaluate whether anthropometric parameters add to PSA measurements in middle-aged men for risk assessment of prostate cancer (PCa) diagnosis and death. After adjusting for PSA, both BMI and weight were significantly associated with an increased risk of PCa death with the odds of a death corresponding to a 10 kg/m2 or 10 kg increase being 1.58 (95% CI 1.10, 2.28; p = 0.013) and 1.14 (95% CI 1.02, 1.26; p = 0.016) times greater, respectively. AUCs did not meaningfully increase with the addition of weight or BMI to prediction models including PSA. In 1974 to 1986, 22,444 Swedish men aged 44 to 50 enrolled in Malmö Preventive Project, Sweden, and provided blood samples and anthropometric data. Rates of PSA screening in the cohort were very low. Documentation of PCa diagnosis and disease-specific death up to 2014 was retrieved through national registries. Among men with anthropometric measurements available at baseline, a total of 1692 men diagnosed with PCa were matched to 4190 controls, and 464 men who died of disease were matched to 1390 controls. Multivariable conditional logistic regression was used to determine whether diagnosis or death from PCa were associated with weight and body mass index (BMI) at adulthood after adjusting for PSA. Men with higher BMI and weight at early middle age have an increased risk of PCa diagnosis and death after adjusting for PSA. However, in a multi-variable numerical statistical model, BMI and weight do not importantly improve the predictive accuracy of PSA. Risk-stratification of screening should be based on PSA without reference to anthropometrics.

Much has been written about the age and formation of Death Valley, but that is one—if not the last—chapter in the fascinating geologic history of this area. Igneous and sedimentary rocks in the Greenwater Range, one mountain range east of Death Valley, tell an earlier story that overlaps with the formation of Death Valley proper. This early story has been told by scientists who have studied these rocks for many years and continue to do so. This field guide was prepared for the first Death Valley Natural History Conference and provides an overview of the geology of the Greenwater Range and the early history (10–0 Ma) of Death Valley.

bcl-2 transgene inhibits T cell death and perturbs thymic self-censorship.

Early death is the fate of most developing T lymphocytes. Because bcl-2 can promote cell survival, we tested its impact in mice expressing an E mu-bcl-2 transgene within the T lymphoid compartment. The T cells showed remarkably sustained viability and some spontaneous differentiation in vitro. They also resisted killing by lymphotoxic agents. Although total T cell numbers and the rate of thymic involution were unaltered, the response to immunization was enhanced, consistent with reduced death of activated T cells. No T cells reactive with self-superantigens appeared in the lymph nodes, but an excess was found in the thymus. These observations, together with previous findings on B cells, suggest that modulated bcl-2 expression is a determinant of life and death in normal lymphocytes.

Time varying prediction of thoughts of death and suicidal ideation in adolescents: weekly ratings over 6-month follow-up.

Suicidal ideation (SI) and thoughts of death are often experienced as fluctuating; therefore a dynamic representation of this highly important indicator of suicide risk is warranted. Theoretical accounts have suggested that affective, behavioral, and interpersonal factors may influence the experience of thoughts of death/SI. This study aimed to examine the prospective and dynamic impact of these constructs in relation to thoughts of death and SI. We assessed adolescents with a recent hospitalization for elevated suicide risk over 6 months. Using the methodology of the Longitudinal Interval Follow-Up Evaluation, weekly ratings for SI, course of depressive illness, affect sensitivity, negative affect intensity, behavioral dysregulation, peer invalidation, and family invalidation were obtained. Using multilevel modeling, results indicated that (a) same-week ratings between these constructs and SI were highly correlated at baseline and throughout follow-up; (b) baseline ratings of affect sensitivity, behavioral dysregulation, and peer invalidation were positive prospective predictors of SI at any week of follow-up; (c) weekly ratings of each of these constructs had significant associations with next-week ratings of SI; and (d) ratings of SI had positive significant associations with next-week ratings on each of the constructs. These results suggest that affective sensitivity, behavioral dysregulation, peer invalidation, and SI are highly associated with SI levels both chronically (over months) and acutely (one week to the next), whereas depression, negative affect intensity, and family invalidation were more acutely predictive of SI. Elevated SI may then aggravate all these factors in a reciprocal manner.

Rich Global Dynamics in a Prey-Predator Model with Allee Effect and Density Dependent Death Rate of Predator

NASA Astrophysics Data System (ADS)

Sen, Moitri; Banerjee, Malay

In this work we have considered a prey-predator model with strong Allee effect in the prey growth function, Holling type-II functional response and density dependent death rate for predators. It presents a comprehensive study of the complete global dynamics for the considered system. Especially to see the effect of the density dependent death rate of predator on the system behavior, we have presented the two parametric bifurcation diagrams taking it as one of the bifurcation parameters. In course of that we have explored all possible local and global bifurcations that the system could undergo, namely the existence of transcritical bifurcation, saddle node bifurcation, cusp bifurcation, Hopf-bifurcation, Bogdanov-Takens bifurcation and Bautin bifurcation respectively.

Last glacial megafaunal death assemblage and early human occupation at Lake Menindee, southeastern Australia

The Tedford subfossil locality at Lake Menindee preserves a diverse assemblage of marsupials, monotremes and placental rodents. Of the 38 mammal taxa recorded at the site, almost a third are of extinct megafauna. Some of the bones are articulated or semi-articulated and include almost complete skeletons, indicating that aeolian sediments rapidly buried the animals following death. New optical ages show the site dates to the early part of the last glacial (55,700 ± 1300 yr weighted mean age). This is close to the 51,200-39,800 yr Australia-wide extinction age for megafauna suggested by Roberts et al. [2001, Science 292:1888-1892], but like all previous researchers, we cannot conclusively determine whether humans were implicated in the deaths of the animals. Although an intrusive hearth at the site dating to 45,100 ± 1400 yr ago is the oldest evidence of human occupation of the Darling River, no artifacts were identified in situ within the sub-fossil-bearing unit. Non-anthropogenic causes, such as natural senescence or ecosystem stress due to climatic aridity, probably explain the mortality of the faunal assemblage at Lake Menindee.

In 2012, over 1.3 million U.S. adults reported that they attempted suicide in the past year, and 39,426 adults died by suicide. This study estimated national suicide case fatality rates among adult suicide attempters (fatal and nonfatal cases) and examined how they varied by sociodemographic characteristics. We pooled data on deaths by suicide (n = 147,427, fatal cases in the U.S.) from the 2008-2011 U S. mortality files and data on suicide attempters who survived (n = 2000 nonfatal cases) from the 2008-2012 National Surveys on Drug Use and Health. Descriptive analyses and multivariable logistic regression models were applied. Among adult suicide attempters in the U.S., the overall 12-month suicide case fatality rate was 3.2% (95% confidence interval (CI) = 2.9%-3.5%). It varied significantly by sociodemographic factors. For those aged 45 or older, the adjusted suicide case fatality rate was higher among men (7.6%) than among women (2.6%) (suicide case fatality rate ratio (SCFRR) = 3.0, 95% CI = 1.83-4.79), was higher among non-Hispanic whites (7.9%) than among non-white minorities (0.8-2.5%) (SCFRRs = 3.2-9.9), and was higher among those with less than high school education (16.0%) than among college graduates (1.8%) (SCFRR = 8.8, 95% CI = 3.83-20.16). Across male and female attempters, being aged 45 or older and non-Hispanic white and having less than secondary school were at a higher risk for death by suicide. Focusing on these demographic characteristics can help identify suicide attempters at higher risk for death by suicide, inform clinical assessments, and improve suicide prevention and intervention efforts by increasing high-risk suicide attempters' access to mental health treatment.

The ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes) trial compared early invasive strategy with a selective invasive strategy in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and an elevated cardiac troponin T. No long-term benefit of an early invasive strategy was found at 1 and 5 years. The aim of this study was to determine the 10-year clinical outcomes of an early invasive strategy versus a selective invasive strategy in patients with NSTE-ACS and an elevated cardiac troponin T. The ICTUS trial was a multicenter, randomized controlled clinical trial that included 1,200 patients with NSTE-ACS and an elevated cardiac troponin T. Enrollment was from July 2001 to August 2003. We collected 10-year follow-up of death, myocardial infarction (MI), and revascularization through the Dutch population registry, patient phone calls, general practitioners, and hospital records. The primary outcome was the 10-year composite of death or spontaneous MI. Additional outcomes included the composite of death or MI, death, MI (spontaneous and procedure-related), and revascularization. Ten-year death or spontaneous MI was not statistically different between the 2 groups (33.8% vs. 29.0%, hazard ratio [HR]: 1.12; 95% confidence interval [CI]: 0.97 to 1.46; p = 0.11). Revascularization occurred in 82.6% of the early invasive group and 60.5% in the selective invasive group. There were no differences in additional outcomes, except for a higher rate of death or MI in the early invasive group compared with the rates for the selective invasive group (37.6% vs. 30.5%; HR: 1.30; 95% CI: 1.07 to 1.58; p = 0.009), driven by a higher rate of procedure-related MI in the early invasive group (6.5% vs. 2.4%; HR: 2.82; 95% CI: 1.53 to 5.20; p = 0.001). In patients with NSTE-ACS and elevated cardiac troponin T levels, an early invasive strategy has no benefit over a selective invasive strategy in reducing the 10-year composite outcome of

Perinatal audit and the three-delays model are increasingly being employed to analyse barriers to perinatal health, at both community and facility level. Using these approaches, our aim was to assess factors that could contribute to perinatal mortality and potentially avoidable deaths at Rwandan hospitals. Perinatal audits were carried out at two main urban hospitals, one at district level and the other at tertiary level, in Kigali, Rwanda, from July 2012 to May 2013. Stillbirths and early neonatal deaths occurring after 22 completed weeks of gestation or more, or weighing at least 500 g, were included in the study. Factors contributing to mortality and potentially avoidable deaths, considering the local resources and feasibility, were identified using a three-delays model. Out of 8424 births, there were 269 perinatal deaths (106 macerated stillbirths, 63 fresh stillbirths, 100 early neonatal deaths) corresponding to a stillbirth rate of 20/1000 births and a perinatal mortality rate of 32/1000 births. In total, 250 perinatal deaths were available for audit. Factors contributing to mortality were ascertained for 79% of deaths. Delay in care-seeking was identified in 39% of deaths, delay in arriving at the health facility in 10%, and provision of suboptimal care at the health facility in 37%. Delay in seeking adequate care was commonly characterized by difficulties in recognising or reporting pregnancy-related danger signs. Lack of money was the major cause of delay in reaching a health facility. Delay in referrals, diagnosis and management of emergency obstetric cases were the most prominent contributors affecting the provision of appropriate and timely care by healthcare providers. Half of the perinatal deaths were judged to be potentially avoidable and 70% of these were fresh stillbirths and early neonatal deaths. Factors contributing to delays underlying perinatal mortality were identified in more than three-quarters of deaths. Half of the perinatal deaths were

Our aim is to investigate starvation as cause of death and social and demographic consequences in the Croatian Quarnero and its hinterland between 1816 and 1825, paying particular attention to the infamous "year of famine" 1817. Our sources were: registers of births, marriages, and deaths from 21 parishes kept at the Croatian State Archives in Rijeka and Zagreb. We collected and processed data for statistical analysis according to the date of baptism (birth), marriage, and death, and according to sex and age. Our focus was on recorded causes of death. Between 1816 and 1825, 15,701 children were baptised (born), and 11,021 people died. Starvation was recorded as cause of death in 255 cases, of which 198 were recorded in the infamous 1817. It was the only year with negative growth in virtually all parishes, with the birth-to-death ratio of 1147:1545. In 1817, the proportion of death by starvation to the total death rate was 12.8% for the entire area, with the highest share recorded in Veprinac (33.3%), Crikvenica (23.3%), and Kastav (15.8%). Death by starvation was more common in men than in women (56.7% vs. 43.3%, respectively). Age distribution was as follows; in the population below 20 years of age the death rate was 42 (16.5% of total deaths), but the most affected age group were infants and children aged 1-4 years (69.0%) whereas in adult population the death rate was 213 (83.5% of total deaths) and the most affected group were the elderly between 60 and 69 years (26.3%). Analysis shows lower birth and marriage rates between 1816 and 1818, followed by a steep rise and a plateau with minimal variation. This study shows that the Croatian Quarnero and its hinterland suffered a great famine in the early 19th century and 1817 in particular, which had left a deep mark on local demography, just like in the neighbouring parts of Croatia and Europe.

Using the Bioage and Snake software the immune and cardiovascular system aging rate was diagnosed in patients having early forms of chronic cerebrovascular diseases (CCVD). The indicators of biological, cardiopulmonary and immunological age were studied in patients showing early symptoms of cerebrovascular insufficiency and dyscirculatory encephalopathy of the 1st stage. The rate of age-dependent physiological changes was diagnosed compared to general body aging rate. Some specific patterns of immune system aging were found in patients with early forms of CCVDs, the cardinal aging symptoms (heterotropia, heterochronia) were verified.

Objective To analyze the process of care provided to premature infants in a neonatal intensive care unit and the factors associated with their mortality. Methods Cross-sectional retrospective study of premature infants in an intensive care unit between 2008 and 2010. The characteristics of the mothers and premature infants were described, and a bivariate analysis was performed on the following characteristics: the study period and the "death" outcome (hospital, neonatal and early) using Pearson's chi-square test, Fisher's exact test or a chi-square test for linear trends. Bivariate and multivariable logistic regression analyses were performed using a stepwise backward logistic regression method between the variables with p<0.20 and the "death" outcome. A p value <0.05 was considered to be significant. Results In total, 293 preterm infants were studied. Increased access to complementary tests (transfontanellar ultrasound and Doppler echocardiogram) and breastfeeding rates were indicators of improving care. Mortality was concentrated in the neonatal period, especially in the early neonatal period, and was associated with extreme prematurity, small size for gestational age and an Apgar score <7 at 5 minutes after birth. The late-onset sepsis was also associated with a greater chance of neonatal death, and antenatal corticosteroids were protective against neonatal and early deaths. Conclusions Although these results are comparable to previous findings regarding mortality among premature infants in Brazil, the study emphasizes the need to implement strategies that promote breastfeeding and reduce neonatal mortality and its early component.

From 2014 to 2015, the age-adjusted death rate for the total U.S. population increased 1.2% from 724.6 to 733.1 per 100,000 population. The rate increased 0.6% from 870.7 to 876.1 for non-Hispanic blacks and 1.4% from 742.8 to 753.2 for non-Hispanic whites. The rate for Hispanic persons did not change significantly. The highest rate was recorded for the non-Hispanic black population, followed by the non-Hispanic white and Hispanic populations.

Despite advances in neonatology, the hypoxic-ischemic injury in the perinatal period remains the single most important cause of brain injury in the newborn, leading to death or lifelong sequelae. Using a sheep model of intrauterine asphyxia, we evaluated the correlation between reactive oxygen species (ROS) overproduction, cytokine expression, and apoptotic cell death. Fetal lambs were assigned to sham group, nonasphyctic animals; and hypoxia-ischemia (HI) group, lambs subjected to 60 minutes of HI) by partial cord occlusion and sacrificed 3 hours later. Different brain regions were separated to quantify the number of apoptotic cells and the same territories were dissociated for flow cytometry studies. Our results suggest that the overproduction of ROS and the early increase in cytokine production after HI in fetal lambs correlate in a significant manner with the apoptotic index, as well as with each brain region evaluated.

Background: Pharmaceutical opioid related deaths have increased. This study aimed to place pharmaceutical opioid overdose deaths within the context of heroin, cocaine, psychostimulants, and pharmaceutical sedative hypnotics, examine demographic trends, and describe common combinations of substances involved in opioid related deaths. Methods: We reviewed deaths among 15-64 year olds in the US from 1999-2009 using death certificate data available through the CDC Wide-Ranging Online Data for Epidemiologic Research (WONDER) Database. We identified International Classification of Disease-10 codes describing accidental overdose deaths, including poisonings related to stimulants, pharmaceutical drugs, and heroin. We used crude and age adjusted death rates (deaths/100,000 person years [p-y] and 95% confidence interval [CI] and multivariable Poisson regression models, yielding incident rate ratios (IRRs), for analysis. Results: The age adjusted death rate related to pharmaceutical opioids increased almost 4-fold from 1999 to 2009 (1.54/100,000 p-y [95% CI 1.49-1.60] to 6.05/100,000 p-y [95% CI 5.95-6.16; p<0.001). From 1999 to 2009, pharmaceutical opioids were responsible for the highest relative increase in overdose death rates (IRR 4.22, 95% CI 3.03-5.87) followed by sedative hypnotics (IRR 3.53, 95% CI 2.11-5.90). Heroin related overdose death rates increased from 2007 to 2009 (1.05/100,000 persons [95% CI 1.00-1.09] to 1.43/100,000 persons [95% CI 1.38-1.48; p<0.001). From 2005-2009 the combination of pharmaceutical opioids and benzodiazepines was the most common cause of polysubstance overdose deaths (1.27/100,000 p-y (95% CI 1.25-1.30). Conclusion: Strategies, such as wider implementation of naloxone, expanded access to treatment, and development of new interventions are needed to curb the pharmaceutical opioid overdose epidemic.

The problem of fuzzy cause-specific death rates in mortality context analysis: the case of Panama City.

PubMed

Bock, S; Gans, P

1993-05-01

In studies of mortality, small and fluctuating numbers of deaths are problems which are caused by infrequent reporting and small spatial unit reporting. To use Panama City as an example, the paper will introduce a Monte Carlo simulation which allows for the analysis of mortality even with small absolute numbers. In addition, Panama City will be used as an example where good medical care is available in every city district, so that social class differences between the districts have a negligible effect on most cause-specific death rates and infant mortality.

The extent to which geographic variability in ICU admission across the United States is driven by patients with lower risk of death is unknown. To determine whether patients at low to moderate risk of death contribute to geographic variation in ICU admission. Retrospective cohort of hospitalizations among Medicare beneficiaries (age > 64 years) admitted for ten common medical and surgical diagnoses (2004 to 2009). We examined population-adjusted rates of ICU admission per 100 hospitalizations in 304 health referral regions (HRR), and estimated the relative risk of ICU admission across strata of regional ICU and risk of death, adjusted for patient and regional characteristics. ICU admission rates varied nearly two-fold across HRR quartiles (quartile 1 to 4: 13.6, 17.3, 20.0, and 25.2 per 100 hospitalizations, respectively). Observed mortality for patients in regions (quartile 4) with the greatest ICU use was 17% compared to 21% in regions with lowest ICU use (quartile 1) (p<0.001). After adjusting for patient and regional characteristics, including regional differences in ICU, skilled nursing, and long-term acute care bed capacity, individuals' risk of death modified the relationship between regional ICU use and an individual's risk of ICU admission (p for interaction<0.001). Region was least important in predicting ICU admission among patients with high (quartile 4) risk of death (RR 1.27, 95% CI 1.22-1.31, for high versus low ICU use regions), and most important for patients with moderate (quartile 2; RR 1.63, 95% CI 1.53-1.72, quartile 3; RR 1.56 95% CI 1.47-1.65) and low (quartile 1) risk of death (RR 1.50, 95% CI 1.41-1.59). There is wide variation in in ICU use by geography, independent of ICU beds and physician supply, for patients with low and moderate risks of death.

Objectives To evaluate whether anthropometric parameters add to PSA measurements in middle-aged men for risk assessment of prostate cancer (PCa) diagnosis and death. Results After adjusting for PSA, both BMI and weight were significantly associated with an increased risk of PCa death with the odds of a death corresponding to a 10 kg/m2 or 10 kg increase being 1.58 (95% CI 1.10, 2.28; p = 0.013) and 1.14 (95% CI 1.02, 1.26; p = 0.016) times greater, respectively. AUCs did not meaningfully increase with the addition of weight or BMI to prediction models including PSA. Materials and Methods In 1974 to 1986, 22,444 Swedish men aged 44 to 50 enrolled in Malmö Preventive Project, Sweden, and provided blood samples and anthropometric data. Rates of PSA screening in the cohort were very low. Documentation of PCa diagnosis and disease-specific death up to 2014 was retrieved through national registries. Among men with anthropometric measurements available at baseline, a total of 1692 men diagnosed with PCa were matched to 4190 controls, and 464 men who died of disease were matched to 1390 controls. Multivariable conditional logistic regression was used to determine whether diagnosis or death from PCa were associated with weight and body mass index (BMI) at adulthood after adjusting for PSA. Conclusions Men with higher BMI and weight at early middle age have an increased risk of PCa diagnosis and death after adjusting for PSA. However, in a multi-variable numerical statistical model, BMI and weight do not importantly improve the predictive accuracy of PSA. Risk-stratification of screening should be based on PSA without reference to anthropometrics. PMID:29464033

Abnormal heart rate turbulence (HRT) has been documented as a strong predictor of total mortality and sudden death in postinfarction patients, but data in patients with congestive heart failure (CHF) are limited. The aim of this study was to evaluate the prognostic significance of HRT for predicting mortality in CHF patients in New York Heart Association (NYHA) class II-III. In 651 CHF patients with sinus rhythm enrolled into the MUSIC (Muerte Subita en Insuficiencia Cardiaca) study, the standard HRT parameters turbulence onset (TO) and slope (TS), as well as HRT categories, were assessed for predicting total mortality and sudden death. HRT was analyzable in 607 patients, mean age 63 years (434 male), 50% of ischemic etiology. During a median follow up of 44 months, 129 patients died, 52 from sudden death. Abnormal TS and HRT category 2 (HRT2) were independently associated with increased all-cause mortality (HR: 2.10, CI: 1.41 to 3.12, P <.001 and HR: 2.52, CI: 1.56 to 4.05, P <.001; respectively), sudden death (HR: 2.25, CI: 1.13 to 4.46, P = .021 for HRT2), and death due to heart failure progression (HR: 4.11, CI: 1.84 to 9.19, P <.001 for HRT2) after adjustment for clinical covariates in multivariate analysis. The prognostic value of TS for predicting total mortality was similar in various groups dichotomized by age, gender, NYHA class, left ventricular ejection fraction, and CHF etiology. TS was found to be predictive for total mortality only in patients with QRS > 120 ms. HRT is a potent risk predictor for both heart failure and arrhythmic death in patients with class II and III CHF.

Death rates by specific causes vary across the 50 states and the District of Columbia.* Information on differences in rates for the leading causes of death among states might help state health officials determine prevention goals, priorities, and strategies. CDC analyzed National Vital Statistics System data to provide national and state-specific estimates of potentially preventable deaths among the five leading causes of death in 2014 and compared these estimates with estimates previously published for 2010. Compared with 2010, the estimated number of potentially preventable deaths changed (supplemental material at https://stacks.cdc.gov/view/cdc/42472); cancer deaths decreased 25% (from 84,443 to 63,209), stroke deaths decreased 11% (from 16,973 to 15,175), heart disease deaths decreased 4% (from 91,757 to 87,950), chronic lower respiratory disease (CLRD) (e.g., asthma, bronchitis, and emphysema) deaths increased 1% (from 28,831 to 29,232), and deaths from unintentional injuries increased 23% (from 36,836 to 45,331). A better understanding of progress made in reducing potentially preventable deaths in the United States might inform state and regional efforts targeting the prevention of premature deaths from the five leading causes in the United States.

The development of antisocial behaviour and sudden violent death.

1988-04-01

In order to detect possible relationships between antisocial behaviour and the incidence of "sudden violent death" in young people, information relating to mortality in antisocial Swedish adolescents has been traced and compiled. A register was drawn up covering those young persons (1,056; 832 boys and 224 girls; mean age 16 years) who were admitted to Swedish probationary schools during the period 1 January - 31 December 1967. Using the registers of immigration and emigration, and causes of death kept by SCB (Statistiska Centralbyrån), mortality occurring between 1 January 1967 - 31 December 1985 was tabulated. One hundred and ten boys (13%) and 22 girls (10%) had died. The deaths had occurred at a rate of approximately seven new deaths per observation year, the youngest being still in their teens when they died. For comparison, the criteria set up by insurance companies for life insurance premiums are based on a death expectancy for healthy Swedish boys and girls in the age groups corresponding to the subjects under observation of 1.2-3.1% for boys and 1.1-2.6% for girls. Eighty-eight percent of the dead boys and 77% of the dead girls had died "sudden violent deaths" - accidents, suicides, death from uncertain causes, murder/manslaughter, or alcohol/drug abuse. For both sexes, death from uncertain causes and suicides were the most frequent single causes of death. Death as a direct result of alcohol/drug abuse occurred only in boys. The results give support to the assumption that a link exists between childhood environment, the development of antisocial behaviour/mental insufficiency and a "sudden violent death" at an early age.(ABSTRACT TRUNCATED AT 250 WORDS)

Respiratory syncytial virus (RSV) is the most common etiology for acute respiratory infection hospital admissions in young children. Case fatality rates for hospitalized patients range between 0% and 3.4%. Recent reports indicate that deaths associated with RSV are uncommon in developed countries. However, the role of this virus as a current cause of mortality in other countries requires further examination. Children with RSV infection admitted between May 2003 and December 2014 to a level 2 specialty hospital in Mexico were included in this analysis. Underlying risk factors, admission to the intensive care unit (ICU) and condition on discharge were assessed to determine the ICU admission and death rates associated to RSV infection. We analyzed data of 1153 patients with RSV infection in whom information regarding underlying illnesses and discharge status was available. Sixty patients (5.2 %) were admitted to the ICU and 12 (1.04 %) died. Relevant underlying conditions were present in 320 (27.7%) patients. Infants with underlying respiratory disorders (excluding asthma) and a history of prematurity had high ICU admission rates (17.1% and 13.8%, respectively). Mortality rates were highest for infants with respiratory disease (excluding asthma) (7.3%), cardiovascular diseases (5.9%) and neurologic disorders (5.3%). The ICU admission and death rates were higher in infants <6 months of age than in other age groups. The ICU admission rate and mortality rate in Mexican infants hospitalized with RSV infection were 5.2% and 1%, respectively. Mortality rates were high in infants with respiratory, cardiovascular and neurologic disorders.

Abstract 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

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

The objective of the study was to examine mortality trends and causes of death among professional athletes from the four major sports in North America who died during their playing careers. 205 deceased athletes who were registered as active when they died from the National Basketball Association (NBA), National Football League (NFL), National Hockey League (NHL), and Major League Baseball (MLB) were examined. Results were compared with the Canadian and U.S. general population. The leading causes of death in players reflected the leading causes of death in the Canadian and U.S. general population (i.e., car accidents). Descriptively, NFL and NBA players had a higher likelihood of dying in a car accident (OR 1.75, 95% CI: 0.91-3.36) compared with NHL and MLB players. In addition, NFL and NBA players had a significantly higher likelihood of dying from a cardiac-related illness (OR 4.44, 95% CI: 1.59-12.43). Mortality trends were disproportionate to team size. Overall, death in active athletes is low. Out of 53 400 athletes who have historically played in the four leagues, only 205 died while active (0.38%). Future examinations into the trends and causes of mortality in elite athlete populations will create a better understanding of health-related risks in elite sport. © 2015 John Wiley & Sons A/S.

Between 1989 and 1998 there was a 21% increase in estimated sudden cardiac death among US women aged 35 to 44 years. In contrast, the sudden cardiac death rate in age-matched men showed a decreasing trend (-2.8%). Due to under-representation of younger adults in published autopsy series, etiologies of sudden cardiac death merit further investigation. We reviewed autopsy and detailed cardiac pathologic findings in younger women (age 35-44 years) from a 270-patient, 13-year (1984-1996) autopsy series of sudden cardiac death, and performed comparisons with findings in age-matched men. Women aged 35 to 44 years constituted 32% of all women in the series compared to men, who constituted 24% of total men (P =.004 vs women). A presumptive cause of sudden cardiac death could not be determined in 13 women (50%). Among women, 6 cases (22%) had significant coronary artery disease. Findings in others included coronary artery anomalies (n = 3), myocarditis (n = 2), hypertrophic cardiomyopathy (n = 1), coronary artery dissection (n = 1) and accessory pathway (n = 1). In younger men, a presumptive cause of sudden cardiac death remained undetermined in only 24% (P =.025 vs younger women), and coronary artery disease accounted for 40% of cases. In younger women, despite autopsy and detailed cardiac pathologic examination, an attributable cause of sudden cardiac death was not determined in 50% of cases; a 2-fold increase compared to men of the same age. Given the dynamic and multifactorial nature of sudden cardiac death, comprehensive population-based investigations are likely to be necessary to further investigate this unexpected sex-based disparity.

Leatherback turtles have an average global hatching success rate of ~50%, lower than other marine turtle species. Embryonic death has been linked to environmental factors such as precipitation and temperature, although, there is still a lot of variability that remains to be explained. We examined how nesting season, the time of nesting each season, the relative position of each clutch laid by each female each season, maternal identity and associated factors such as reproductive experience of the female (new nester versus remigrant) and period of egg retention between clutches (interclutch interval) affected hatching success and stage of embryonic death in failed eggs of leatherback turtles nesting at Playa Grande, Costa Rica. Data were collected during five nesting seasons from 2004/05 to 2008/09. Mean hatching success was 50.4%. Nesting season significantly influenced hatching success in addition to early and late stage embryonic death. Neither clutch position nor nesting time during the season had a significant affect on hatching success or the stage of embryonic death. Some leatherback females consistently produced nests with higher hatching success rates than others. Remigrant females arrived earlier to nest, produced more clutches and had higher rates of hatching success than new nesters. Reproductive experience did not affect stage of death or the duration of the interclutch interval. The length of interclutch interval had a significant affect on the proportion of eggs that failed in each clutch and the developmental stage they died at. Intrinsic factors such as maternal identity are playing a role in affecting embryonic death in the leatherback turtle.

Objective: The dynamics of morbidity, disability and death rates due to malignant neoplasms in the population in Uralsk city of the Republic of Kazakhstan were studied for 2011-2015, with a focus on age and sex, as well as tumor location. Methods: Statistics for total morbidity, primary disability and mortality from cancer in the adult population of the city of Uralsk for 2011-2015 were calculated per 100 thousand. Estimation of morbidity was based on data from form - №12 «Report on the number of diseases registered in patients living in the area of health care organizations and patient population under medical observation”. Evaluation of primary disability was based on form №7 «The distribution of newly recognized disabled by disease class, age, sex and disability groups” for 2011-2015 in Ural city and analysis of cancer was carried out using annual form 7 “Report on the sick, and diseases of malignant neoplasms”. Result: The most common localizations of cancer were the trachea, bronchi, lungs, stomach and mammary glands. High death rates were noted for patients with cancer of the trachea, bronchi, lung, as compared to stomach and esophagus. Conclusion: The results of our investigation and data in the literature indicate that regional characteristics influence the impact of risk factors associated with cancer. An unfavorable environmental background contributes to ill health of urban populations, contributing to development of cancer. Moreover behavioral risk factors are very important, such as smoking, alcohol drinking, and an unhealthy diet. All these factors require urgent adoption of a package of measures for prevention, early detection and timely treatment. Detailed study of cancer is necessary to develop national programs and activities for prevention and control. Creative Commons Attribution License

To compare the rates of death per volume of drug dispensed for antidepressants in New Zealand. Deaths from antidepressant poisonings were identified from the reports of coronial inquiries for New Zealand in 2001. Prescriptions for antidepressant medications were identified from the PharmHouse database from 1 January 2001 to 31 December 2001. The rates of deaths (95% CI) per prescription, tablet/capsule or defined daily dose were calculated for individual antidepressants and classes of antidepressant. There were 200 poisoning deaths recorded in the database for New Zealand in 2001. Antidepressants were involved in 41 deaths, and death was attributed to an antidepressant in 23 cases. There were 5.52 (95% CI 3.85-7.68) deaths per 100 000 prescriptions for tricyclic antidepressants (TCAs) and 2.51 (1.57-3.79) deaths per 100 000 prescriptions for selective serotonin reuptake inhibitors (SSRIs). There was marked variability in rates of death per volume of drug dispensed between individual antidepressants. SSRIs have lower rates of death per volume of drug dispensed than TCAs and there is also variation in these rates within these classes of drugs. Toxicity in overdose should be considered when prescribing antidepressants.

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.

Exposing misclassified HIV/AIDS deaths in South Africa.

To quantify the deaths from human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) that are misattributed to other causes in South Africa's death registration data and to adjust for this bias. Deaths in the World Health Organization's mortality database were distributed among 48 mutually exclusive causes. For each cause, age- and sex-specific global death rates were compared with the average rate among people aged 65-69, 70-74 and 75-79 years to generate "relative" global death rates. Relative rates were also computed for South Africa alone. Differences between global and South African relative death rates were used to identify the causes to which deaths from HIV/AIDS were misattributed in South Africa and quantify the HIV/AIDS deaths misattributed to each. These deaths were then reattributed to HIV/AIDS. In South Africa, deaths from HIV/AIDS are often misclassified as being caused by 14 other conditions. Whereas in 1996-2006 deaths attributed to HIV/AIDS accounted for 2.0-2.5% of all registered deaths in South Africa, our analysis shows that the true cause-specific mortality fraction rose from 19% (uncertainty range: 7-28%) to 48% (uncertainty range: 38-50%) over that period. More than 90% of HIV/AIDS deaths were found to have been misattributed to other causes during 1996-2006. Adjusting for cause of death misclassification, a simple procedure that can be carried out in any country, can improve death registration data and provide empirical estimates of HIV/AIDS deaths that may be useful in assessing estimates from demographic models.

An estimated 50,000 persons die annually in the United States as a result of violence-related injuries. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) regarding violent deaths from 16 U.S. states for 2005. Results are reported by sex, age group, race/ethnicity, marital status, location of injury, method of injury, circumstances of injury, and other selected characteristics. 2005. NVDRS collects data regarding violent deaths obtained from death certificates, coroner/medical examiner reports, and law enforcement reports. NVDRS began operation in 2003 with seven states (Alaska, Maryland, Massachusetts, New Jersey, Oregon, South Carolina, and Virginia) participating; six states (Colorado, Georgia, North Carolina, Oklahoma, Rhode Island, and Wisconsin) joined in 2004 and four (California, Kentucky, New Mexico, and Utah) in 2005, for a total of 17 states. This report includes data from 16 states; data from California are not included in this report because NVDRS has been implemented only in a limited number of California cities and counties rather than statewide as in other states. For 2005, a total of 15,495 fatal incidents involving 15,962 violent deaths occurred in the 16 NVDRS states included in this report. The majority (56.1%) of deaths were suicides, followed by homicides and deaths involving legal interventions (29.6%), violent deaths of undetermined intent (13.3%), and unintentional firearm deaths (0.7%). Fatal injury rates varied by sex, race/ethnicity, age group, and method of injury. Rates were substantially higher for males than for females and for American Indians/Alaska Natives (AI/ANs) and blacks than for whites and Hispanics. Rates were highest for persons aged 20-24 years. For method of injury, the three highest rates were reported for firearms, poisonings, and hanging/strangulation/suffocation. Suicides occurred at higher rates among males, AI/ANs, whites, and older persons and most often involved the use of

Little research in low-income countries has compared the social and cultural ramifications of loss in childbearing, yet the social experience of pregnancy loss and early neonatal death may affect demographers' ability to measure their incidence. Ninety-five qualitative reproductive narratives were collected from 50 women in rural southern Tanzania who had recently suffered infertility, miscarriage, stillbirth or early neonatal death. An additional 31 interviews with new mothers and female elders were used to assess childbearing norms and social consequences of loss in childbearing. We found that like pregnancy, stillbirth and early neonatal death are hidden because they heighten women's vulnerability to social and physical harm, and women's discourse and behaviors are under strong social control. To protect themselves from sorcery, spiritual interference, and gossip--as well as stigma should a spontaneous loss be viewed as an induced abortion--women conceal pregnancies and are advised not to mourn or grieve for "immature" (late-term) losses. Twelve of 30 respondents with pregnancy losses had been accused of inducing an abortion; 3 of these had been subsequently divorced. Incommensurability between Western biomedical and local categories of reproductive loss also complicates measurement of losses. Similar gender inequalities and understandings of pregnancy and reproductive loss in other low-resource settings likely result in underreporting of these losses elsewhere. Cultural, terminological, and methodological factors that contribute to inaccurate measurement of stillbirth and early neonatal death must be considered in designing surveys and other research methods to measure pregnancy, stillbirth, and other sensitive reproductive events.

Objectives. We explored associations between the abolition of Jim Crow laws (i.e., state laws legalizing racial discrimination overturned by the 1964 US Civil Rights Act) and birth cohort trends in infant death rates. Methods. We analyzed 1959 to 2006 US Black and White infant death rates within and across sets of states (polities) with and without Jim Crow laws. Results. Between 1965 and 1969, a unique convergence of Black infant death rates occurred across polities; in 1960 to 1964, the Black infant death rate was 1.19 times higher (95% confidence interval [CI] = 1.18, 1.20) in the Jim Crow polity than in the non–Jim Crow polity, whereas in 1970 to 1974 the rate ratio shrank to and remained at approximately 1 (with the 95% CI including 1) until 2000, when it rose to 1.10 (95% CI = 1.08, 1.12). No such convergence occurred for Black–White differences in infant death rates or for White infants. Conclusions. Our results suggest that abolition of Jim Crow laws affected US Black infant death rates and that valid analysis of societal determinants of health requires appropriate comparison groups.

Trinity College Dublin remains one of the Medical Schools that uses traditional dissection to teach anatomy, exposing students from the first week of entry to cadavers. This early exposure makes it imperative that issues surrounding death and donor remains are explored early on within the main structure of the curriculum. The School of Medicine began a programme of Medical Humanities student-selected modules (SSMs) in 2010, and the opportunity to offer a module on medical ethics regarding death and dignity was taken. A course was devised that touched only lightly on subjects such as palliative care and the concept of a good death. The course focused much more strongly on the reality of death as part of cultural and societal identity and placement. This was facilitated by field trips to settings where discussions regarding death, dying and dignity were commonplace and authentic experiences, rather than classroom discussions based on theoretical circumstances that may not yet have been experienced by the student. The module ran very well, with students feeling that they had had a chance to think critically about the role of death as an event with significance within society and culture, rather than purely in a medico-legal framework. Options to extend the module to the compulsory element of the course, to be built upon in later years looking at more technical aspects surrounding death, are being explored. © Blackwell Publishing Ltd 2011.

Abstract Objective To quantify the deaths from human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) that are misattributed to other causes in South Africa’s death registration data and to adjust for this bias. Methods Deaths in the World Health Organization’s mortality database were distributed among 48 mutually exclusive causes. For each cause, age- and sex-specific global death rates were compared with the average rate among people aged 65–69, 70–74 and 75–79 years to generate “relative” global death rates. Relative rates were also computed for South Africa alone. Differences between global and South African relative death rates were used to identify the causes to which deaths from HIV/AIDS were misattributed in South Africa and quantify the HIV/AIDS deaths misattributed to each. These deaths were then reattributed to HIV/AIDS. Findings In South Africa, deaths from HIV/AIDS are often misclassified as being caused by 14 other conditions. Whereas in 1996–2006 deaths attributed to HIV/AIDS accounted for 2.0–2.5% of all registered deaths in South Africa, our analysis shows that the true cause-specific mortality fraction rose from 19% (uncertainty range: 7–28%) to 48% (uncertainty range: 38–50%) over that period. More than 90% of HIV/AIDS deaths were found to have been misattributed to other causes during 1996–2006. Conclusion Adjusting for cause of death misclassification, a simple procedure that can be carried out in any country, can improve death registration data and provide empirical estimates of HIV/AIDS deaths that may be useful in assessing estimates from demographic models.

Mathematical models of HIV-1 infection can help interpret drug treatment experiments and improve our understanding of the interplay between HIV-1 and the immune system. We develop and analyze an age- structured model of HIV-1 infection that allows for variations in the death rate of productively infected T cells and the production rate of viral particles as a function of the length of time a T cell has been infected. We show that this model is a generalization of the standard differential equation and of delay models previously used to describe HIV-1 infection, and provides a means for exploring fundamental issues of viral production and death. We show that the model has uninfected and infected steady states, linked by a transcritical bifurcation. We perform a local stability analysis of the nontrivial equilibrium solution and provide a general stability condition for models with age structure. We then use numerical methods to study solutions of our model focusing on the analysis of primary HIV infection. We show that the time to reach peak viral levels in the blood depends not only on initial conditions but also on the way in which viral production ramps up. If viral production ramps up slowly, we find that the time to peak viral load is delayed compared to results obtained using the standard (constant viral production) model of HIV infection. We find that data on viral load changing over time is insufficient to identify the functions specifying the dependence of the viral production rate or infected cell death rate on infected cell age. These functions must be determined through new quantitative experiments.

The rate of hepatitis C virus recurrence after donation after cardiac death liver transplant is not clearly defined. This is a retrospective review of 39 donations after cardiac death-liver transplant recipients. Biopsies were performed at 6, 12, 24, and 36 months for all hepatitis C virus positive donation after cardiac death recipients. The 6-, 12-, 24-, and 36-month severe hepatitis C virus recurrence rates were 60%, 73%, 87%, and 94%. A histologic comparison group of 26 long-surviving hepatitis C virus positive donation after neurologic death recipients had severe hepatitis C virus recurrence 27%, 31%, 42%, and 52% of the time. Six of the 19 hepatitis C virus donation after cardiac death patients developed cirrhosis at a median of 56 months (range, 14-119 months). There was no significant 3-year allograft and patient survival difference between hepatitis C virus and nonhepatitis C virus donation after cardiac death recipients. The factors most associated with decreased survival in the entire cohort included biliary and vascular complications. Organs procured by our institution's attending surgeons were associated with a better 3-year allograft survival. Severe hepatitis C virus recurrence was nearly universal but did not lead to increased graft loss when compared with nonhepatitis C virus donation after cardiac death at 3 years. These data may justify early interferon treatment in these at-risk patients.

Fast maximum likelihood estimation of mutation rates using a birth-death process.

PubMed

Wu, Xiaowei; Zhu, Hongxiao

2015-02-07

Since fluctuation analysis was first introduced by Luria and Delbrück in 1943, it has been widely used to make inference about spontaneous mutation rates in cultured cells. Under certain model assumptions, the probability distribution of the number of mutants that appear in a fluctuation experiment can be derived explicitly, which provides the basis of mutation rate estimation. It has been shown that, among various existing estimators, the maximum likelihood estimator usually demonstrates some desirable properties such as consistency and lower mean squared error. However, its application in real experimental data is often hindered by slow computation of likelihood due to the recursive form of the mutant-count distribution. We propose a fast maximum likelihood estimator of mutation rates, MLE-BD, based on a birth-death process model with non-differential growth assumption. Simulation studies demonstrate that, compared with the conventional maximum likelihood estimator derived from the Luria-Delbrück distribution, MLE-BD achieves substantial improvement on computational speed and is applicable to arbitrarily large number of mutants. In addition, it still retains good accuracy on point estimation. Published by Elsevier Ltd.

Dreier, Rolf P; Mackenbach, Johan P

Salomon van Rusting was a medical doctor from Amsterdam who lived and worked around the early 1700 s. He wrote one of the few Dutch Death Dances, naming it 'Het Schouw-Tooneel des Doods'. A Death Dance was an artistic expression of human death popular in the Late Middle Ages. The traditional Death Dance invited acknowledgement of the vanity of worldly existence ('memento mori') by portraying human subjects' encounters with 'Death'. This paper describes the context in which Van Rusting's work arose and briefly characterizes its highly original and, for the most part, rather burlesque nature. In contrast to other Death Dances, Van Rusting's work does not represent medicine as being powerless in the face of death. His work strikes us as having almost modern confidence in our own ability to avoid an untimely death by living sensibly.

High Israeli mortality rates from diabetes and renal failure - Can international comparison of multiple causes of death reflect differences in choice of underlying cause?

The age-adjusted mortality rate in Israel is low compared to most Western countries although mortality rates from diabetes and renal failure in Israel are amongst the highest, while those from cardiovascular diseases (CVD) are amongst the lowest. This study aims to assess validity of choice of underlying causes (UC) in Israel by analyzing Israeli and international data on the prevalence of these diseases as multiple causes of death (MCOD) compared to UC, and data on comorbidity (MCOD based). Age-adjusted death rates were calculated for UC and MCOD and the corresponding ratio of multiple to underlying cause of death (SRMU) for available years between 1999 and 2012. Comorbidity was explored by calculating cause of death association indicators (CDAI) and frequency of comorbid disease. These results were compared to data from USA, France, Italy, Australia and the Czech Republic for 2009 or other available year. Mortality rates for all these diseases except renal failure have decreased in Israel between 1999 and 2012 as UC and MCOD. In 2009, the SRMU for diabetes was 2.7, slightly lower than other Western countries (3.0-3.5) showing more frequent choice as UC. Similar results were found for renal failure. In contrast, the SRMU for ischemic heart disease (IHD) and cerebrovascular disease were 2.0 and 2.6, respectively, higher than other countries (1.4-1.6 and 1.7-1.9, respectively), showing less frequent choice as UC. CDAI data showed a strong association between heart and cerebrovascular disease, and diabetes in all countries. In Israel, 40 % of deaths with UC diabetes had IHD and 24 % had cerebrovascular disease. Renal disease was less strongly associated with IHD. This international comparison suggests that diabetes and renal failure may be coded more frequently in Israel as UC, sometimes instead of heart and cerebrovascular disease. Even with some changes in coding, mortality rates would be high compared to other countries, similar to the comparatively high

Although cause-of-death analyses are very important to define public health policy priorities and to evaluate health programs, there is very limited knowledge about mortality profiles and trends in Turkey. The aim of this study was to measure the trends in mortality within three broad cause-of-death groups and their distribution by age groups and gender and to describe the changes of leading causes of death between 1980 and 2013 in Turkey. Descriptive study. In the study, data on the number of deaths by year, gender, age and cause was obtained from the Turkish Statistical Institute. The causes of death were classified as group I: communicable, maternal, perinatal, and nutritional conditions; group II: non-communicable diseases (NCDs); and group III: injuries. Unknown or ill-defined causes of death were distributed within group I and group II. The percentage distribution of the cause-of-death groups by gender and age groups between 1980 and 2013 was identified. Age-standardized mortality rates (ASMRs) per 100,000 of broad causes-of-death groups were calculated using European Standard Population 1976 between 1980 and 2008. Changes in mortality rates per hundred were calculated using the formula ([the rate of last year of the period-the rate of the first year of the period]/the rate of the first year of the period). Gender and age-specific data were analyzed using the Joinpoint software to examine trends and significant changes in trends of mortality rates. Crude death rates for group I, group II, and group III were 157.3, 147.2, and 21.4 per 100,000 in 1980 and 35.3, 377.5, and 15.8 in 2008 for males; 161.8, 120.2, and 5.8 in 1980 and 38.6, 318.4, and 6.4 in 2008 for females, respectively. ASMRs for group I, group II, and group III were 146.3, 394.3, and 29.3 per 100,000 in 1980 and 49.7, 723.6, and 18.8 in 2008 for males; 138.0, 291.5, and 7.6 per 100,000 in 1980 and 47.7, 478.8, and 7.2 in 2008 for females, respectively.

Among former prisoners, a high rate of death has been documented in the early postrelease period, particularly from drug-related causes. Little is known about risk factors and trends in postrelease mortality in the past decade, especially given general population increases in overdose deaths from pharmaceutical opioids. To determine postrelease mortality between 1999 and 2009; cause-specific mortality rates; and whether sex, calendar year, and custody factors were risk factors for all-cause, overdose, and opioid-related deaths. Cohort study. Prison system of the Washington State Department of Corrections. 76 208 persons released from prison. Identities were linked probabilistically to the National Death Index to identify deaths and causes of death, and mortality rates were calculated. Cox proportional hazards regression estimated the effect of age, sex, race or ethnicity, whether the incarceration resulted from a violation of terms of the person's community supervision, length of incarceration, release type, and calendar year on the hazard ratio (HR) for death. The all-cause mortality rate was 737 per 100 000 person-years (95% CI, 708 to 766) (n = 2462 deaths). Opioids were involved in 14.8% of all deaths. Overdose was the leading cause of death (167 per 100 000 person-years [CI, 153 to 181]), and overdose deaths in former prisoners accounted for 8.3% of the overdose deaths among persons aged 15 to 84 years in Washington from 2000 to 2009. Women were at increased risk for overdose (HR, 1.38 [CI, 1.12 to 1.69]) and opioid-related deaths (HR, 1.39 [CI, 1.09 to 1.79]). The study was done in only 1 state. Innovation is needed to reduce the risk for overdose among former prisoners. National Institute on Drug Abuse and the Robert Wood Johnson Foundation.

Struck-by-lightning deaths in the United States.

The objective of the research reported here was to examine the epidemiologic characteristics of struck-by-lightning deaths. Using data from both the National Centers for Health Statistics (NCHS) multiple-cause-of-death tapes and the Census of Fatal Occupational Injuries (CFOI), which is maintained by the Bureau of Labor Statistics, the authors calculated numbers and annualized rates of lightning-related deaths for the United States. They used resident estimates from population microdata files maintained by the Census Bureau as the denominators. Work-related fatality rates were calculated with denominators derived from the Current Population Survey of employment data. Four illustrative investigative case reports of lightning-related deaths were contributed by the New Mexico Office of the Medical Investigator. It was found that a total of 374 struck-by-lightning deaths had occurred during 1995-2000 (an average annualized rate of 0.23 deaths per million persons). The majority of deaths (286 deaths, 75 percent) were from the South and the Midwest. The numbers of lightning deaths were highest in Florida (49 deaths) and Texas (32 deaths). A total of 129 work-related lightning deaths occurred during 1995-2002 (an average annual rate of 0.12 deaths per million workers). Agriculture and construction industries recorded the most fatalities at 44 and 39 deaths, respectively. Fatal occupational injuries resulting from being struck by lightning were highest in Florida (21 deaths) and Texas (11 deaths). In the two national surveillance systems examined, incidence rates were higher for males and people 20-44 years of age. In conclusion, three of every four struck-by-lightning deaths were from the South and the Midwest, and during 1995-2002, one of every four struck-by-lightning deaths was work-related. Although prevention programs could target the entire nation, interventions might be most effective if directed to regions with the majority of fatalities because they have the

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.

Reducing Potentially Excess Deaths from the Five Leading Causes of Death in the Rural United States

In 2014, the all-cause age-adjusted death rate in the United States reached a historic low of 724.6 per 100,000 population (1). However, mortality in rural (nonmetropolitan) areas of the United States has decreased at a much slower pace, resulting in a widening gap between rural mortality rates (830.5) and urban mortality rates (704.3) (1). During 1999–2014, annual age-adjusted death rates for the five leading causes of death in the United States (heart disease, cancer, unintentional injury, chronic lower respiratory disease (CLRD), and stroke) were higher in rural areas than in urban (metropolitan) areas (Figure 1). In most public health regions (Figure 2), the proportion of deaths among persons aged <80 years (U.S. average life expectancy) (2) from the five leading causes that were potentially excess deaths was higher in rural areas compared with urban areas (Figure 3). Several factors probably influence the rural-urban gap in potentially excess deaths from the five leading causes, many of which are associated with sociodemographic differences between rural and urban areas. Residents of rural areas in the United States tend to be older, poorer, and sicker than their urban counterparts (3). A higher proportion of the rural U.S. population reports limited physical activity because of chronic conditions than urban populations (4). Moreover, social circumstances and behaviors have an impact on mortality and potentially contribute to approximately half of the determining causes of potentially excess deaths (5).

Occupational Deaths among Healthcare Workers

PubMed Central

Eisenberg, Leon

2005-01-01

Recent experiences with severe acute respiratory syndrome and the US smallpox vaccination program have demonstrated the vulnerability of healthcare workers to occupationally acquired infectious diseases. However, despite acknowledgment of risk, the occupational death rate for healthcare workers is unknown. In contrast, the death rate for other professions with occupational risk, such as police officer or firefighter, has been well defined. With available information from federal sources and calculating the additional number of deaths from infection by using data on prevalence and natural history, we estimate the annual death rate for healthcare workers from occupational events, including infection, is 17–57 per 1 million workers. However, a much more accurate estimate of risk is needed. Such information could inform future interventions, as was seen with the introduction of safer needle products. This information would also heighten public awareness of this often minimized but essential aspect of patient care. PMID:16022771

Divorce and Death: Forty Years of the Charleston Heart Study

Nietert, Paul J.

2010-01-01

Forty years of follow-up data from the Charleston Heart Study (CHS) were used to examine the risk for early mortality associated with marital separation or divorce in a sample of over 1,300 adults assessed on several occasions between 1960 and 2000. Participants who were separated or divorced at study inception evidenced significantly higher rates of early mortality, and these results held after adjusting for baseline health status and other demographic variables. Being separated or divorced throughout the CHS follow-up window was one of the strongest predictors of early mortality. However, the excess mortality risk associated with remaining separated/divorced was completely eliminated when participants were re-classified as having ever experienced a marital separation or divorce. These findings suggest a key determinant of early death is the amount of time people live as separated or divorced and/or dimensions of personality that predict divorce as well as a decreased likelihood of future remarriage.

Patients were randomly assigned to receive either early eptifibatide (two boluses, each containing 180 microg per kilogram of body weight, administered 10 minutes apart, and a standard infusion > or = 12 hours before angiography) or a matching placebo infusion with provisional use of eptifibatide after angiography (delayed eptifibatide). The primary efficacy end point was a composite of death, myocardial infarction, recurrent ischemia requiring urgent revascularization, or the occurrence of a thrombotic complication during percutaneous coronary intervention that required bolus therapy opposite to the initial study-group assignment ("thrombotic bailout") at 96 hours. The key secondary end point was a composite of death or myocardial infarction within the first 30 days. Key safety end points were bleeding and the need for transfusion within the first 120 hours after randomization. The primary end point occurred in 9.3% of patients in the early-eptifibatide group and in 10.0% in the delayed-eptifibatide group (odds ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P=0.23). At 30 days, the rate of death or myocardial infarction was 11.2% in the early-eptifibatide group, as compared with 12.3% in the delayed-eptifibatide group (odds ratio, 0.89; 95% CI, 0.79 to 1.01; P=0.08). Patients in the early-eptifibatide group had significantly higher rates of bleeding and red-cell transfusion. There was no significant difference between the two groups in rates of severe bleeding or nonhemorrhagic serious adverse events. In patients who had acute

The renewed interest in donation after cardio-circulatory death (DCD) started in the 1990s following the limited success of the transplant community to expand the donation after brain-death (DBD) organ supply and following the request of potential DCD families. Since then, DCD organ procurement and transplantation activities have rapidly expanded, particularly for non-vital organs, like kidneys. In liver transplantation (LT), DCD donors are a valuable organ source that helps to decrease the mortality rate on the waiting lists and to increase the availability of organs for transplantation despite a higher risk of early graft dysfunction, more frequent vascular and ischemia-type biliary lesions, higher rates of re-listing and re-transplantation and lower graft survival, which are obviously due to the inevitable warm ischemia occurring during the declaration of death and organ retrieval process. Experimental strategies intervening in both donors and recipients at different phases of the transplantation process have focused on the attenuation of ischemia-reperfusion injury and already gained encouraging results, and some of them have found their way from pre-clinical success into clinical reality. The future of DCD-LT is promising. Concerted efforts should concentrate on the identification of suitable donors (probably Maastricht category III DCD donors), better donor and recipient matching (high risk donors to low risk recipients), use of advanced organ preservation techniques (oxygenated hypothermic machine perfusion, normothermic machine perfusion, venous systemic oxygen persufflation), and pharmacological modulation (probably a multi-factorial biologic modulation strategy) so that DCD liver allografts could be safely utilized and attain equivalent results as DBD-LT.

Despite emerging data of cost savings under palliative care in various regions, no such data have been generated in response to the high burden of terminal illness in Africa. This evaluation of a novel hospital-based palliative care service for patients with advanced organ failure in urban South Africa aimed to determine whether the service reduces admissions and increases home death rates compared with the same fixed time period of standard hospital care. Data on admissions and place of death were extracted from routine hospital activity records for a fixed period before death, using standard patient daily expense rates. Data from the first 56 consecutive deaths under the new service (intervention group) were compared with 48 consecutive deaths among patients immediately before the new service (historical controls). Among the intervention and control patients, 40 of 56 (71.4%) and 47 of 48 (97.9%), respectively, had at least one admission (P < 0.001). The mean number of admissions for the intervention and control groups was 1.39 and 1.98, respectively (P < 0.001). The mean total number of days spent admitted for intervention and control groups was 4.52 and 9.3 days, respectively (P < 0.001). For the intervention and control patients, a total of 253 and 447 admission days were recorded, respectively, with formal costs of $587 and $1209, respectively. For the intervention and control groups, home death was achieved by 33 of 56 (58.9%) and nine of 48 (18.8%), respectively (P ≤ 0.001). These data demonstrate that an outpatient hospital-based service reduced admissions and improved the rate of home deaths and offers a feasible and cost-effective model for such settings.

While the high prevalence of preterm births and its impact on infant mortality in the US have been widely acknowledged, recent data suggest that even full-term births in the US face substantially higher mortality risks compared to European countries with low infant mortality rates. In this paper, we use the most recent birth records in the US to more closely analyze the primary causes underlying mortality rates among full-term births. Linked birth and death records for the period 2010-2012 were used to identify the state- and cause-specific burden of infant mortality among full-term infants (born at 37-42 weeks of gestation). Multivariable logistic models were used to assess the extent to which state-level differences in full-term infant mortality (FTIM) were attributable to observed differences in maternal and birth characteristics. Random effects models were used to assess the relative contribution of state-level variation to FTIM. Hypothetical mortality outcomes were computed under the assumption that all states could achieve the survival rates of the best-performing states. A total of 10,175,481 infants born full-term in the US between January 1, 2010, and December 31, 2012, were analyzed. FTIM rate (FTIMR) was 2.2 per 1,000 live births overall, and ranged between 1.29 (Connecticut, 95% CI 1.08, 1.53) and 3.77 (Mississippi, 95% CI 3.39, 4.19) at the state level. Zero states reached the rates reported in the 6 low-mortality European countries analyzed (FTIMR < 1.25), and 13 states had FTIMR > 2.75. Sudden unexpected death in infancy (SUDI) accounted for 43% of FTIM; congenital malformations and perinatal conditions accounted for 31% and 11.3% of FTIM, respectively. The largest mortality differentials between states with good and states with poor FTIMR were found for SUDI, with particularly large risk differentials for deaths due to sudden infant death syndrome (SIDS) (odds ratio [OR] 2.52, 95% CI 1.86, 3.42) and suffocation (OR 4.40, 95% CI 3.71, 5.21).

fatality risk had declined 61% from its high in 1988, and SUV risk had declined 79% from its high in 1988. The risk of driver death in 2009 model passenger vehicles was 8% lower than that in 2008 models and about half that in 1984 models. Changes in vehicles, whether from government regulations and consumer testing that led to advanced safety designs or from other factors such as consumer demand for different sizes and types of vehicles, have been key contributors to the decline in U.S. motor vehicle occupant crash death rates since the mid-1990s. Since the early 1990s, environmental and behavioral risk factors have not shown similar improvement, until the recession of 2007, even though there are many empirically proven countermeasures that have been inadequately applied.

Organ donations continue to fall, failing to meet the clinical requirements for heart transplantation. Furthermore, the pathophysiology of brain stem death including hormonal and inflammatory changes may lead to significant donor heart injury. Early donor management may potentially alleviate these changes and therefore increase the number of available hearts for transplantation. We aimed to investigate whether early management of borderline donors can increase the heart retrieval rate. Between September 2011 and February 2013, we performed early donor management of 26 potential heart donors in the intensive care units of the respective donor hospitals. At the time of referral donors were considered as borderline based on high-dose inotrope requirements, history of hypertension and cardiopulmonary resuscitation. Our management protocol included insertion of a pulmonary artery catheter and performance of cardiac output studies, weaning noradrenaline and commencing arginine vasopressin, and administration of tri-iodothyronine, methylprednisolone and insulin. Our primary end-point was donor heart acceptance, depending collectively on the results of cardiac output studies, cardiac contractility and coronary artery patency at the time of retrieval operation. We retrieved 14 (56%) borderline hearts after donor management (Group A) with a 30-day survival rate of 86%. Twelve (44%) organs were declined due to poor heart function (n=8; 66.7%; P<0.001) and/or palpable coronary artery disease (n=4; 33.3%; P=0.018) (Group B). The mean age of Groups A and B was 42.77 and 47.78 years, respectively (P=0.19). Most of the female donors, i.e. 10 (83%), were declined, and only 4 (27%) were accepted (P=0.005). Majority of patients in both groups (Group A: 71.4%; n=10; and Group B: 66.7%; n=8) were on high-dose noradrenaline (>0.08 μg kg(-1) min(-2)) at the time of donor offer. Group A had a mean cardiac output of 6.29 and 3.09 l/min for Group B (P=0.01). A positive smoking history was

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

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. PMID:24503974

Parent & Child Perceptions of Child Health after Sibling Death.

Roche, Rosa M; Brooten, Dorothy; Youngblut, JoAnne M

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. 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. 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. 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.

Behavioral studies suggest that humans evolve the capacity to cope with anxiety induced by the awareness of death's inevitability. However, the neurocognitive processes that underlie online death-related thoughts remain unclear. Our recent functional MRI study found that the processing of linguistic cues related to death was characterized by decreased neural activity in human insular cortex. The current study further investigated the time course of neural processing of death-related linguistic cues. We recorded event-related potentials (ERP) to death-related, life-related, negative-valence, and neutral-valence words in a modified Stroop task that required color naming of words. We found that the amplitude of an early frontal/central negativity at 84-120 ms (N1) decreased to death-related words but increased to life-related words relative to neutral-valence words. The N1 effect associated with death-related and life-related words was correlated respectively with individuals' pessimistic and optimistic attitudes toward life. Death-related words also increased the amplitude of a frontal/central positivity at 124-300 ms (P2) and of a frontal/central positivity at 300-500 ms (P3). However, the P2 and P3 modulations were observed for both death-related and negative-valence words but not for life-related words. The ERP results suggest an early inverse coding of linguistic cues related to life and death, which is followed by negative emotional responses to death-related information.
