  1. Mycelial growth rate and toxin production in the seed pathogen Pyrenophora semeniperda: Resource trade-offs and temporally varying selection (United States)

    S. E. Meyer; M. Masi; S. Clement; T. L. Davis; J. Beckstead


    Pyrenophora semeniperda, an important pathogen in Bromus tectorum seed banks in semi-arid western North America, exhibits >4-fold variation in mycelial growth rate. Host seeds exhibit seasonal changes in dormancy that affect the risk of pathogen-caused mortality. The hypothesis tested is that contrasting seed dormancy phenotypes select for contrasting strategies...

  2. Mating-type locus characterization and variation in Pyrenophora semeniperda (United States)

    Julie Leanna Henry


    Pyrenophora semeniperda is a generalist fungal pathogen that occurs primarily on monocot seed hosts. It is in the phylum Ascomycota, which includes both self-compatible (homothallic) and self-incompatible (heterothallic) species. Homothallic fungal species contain complementary mating-type (MAT) idiomorphs in a single unikaryotic strain, while heterothallic strains...

  3. Race structure of Pyrenophora tritici-repentis in Morocco

    Directory of Open Access Journals (Sweden)

    Fernanda M. GAMBA


    Full Text Available The virulence of 135 single-spore isolates of Pyrenophora tritici-repentis, collected from durum wheat fields representing most of the major agro-ecological zones of Morocco from 2013 to 2015, was assessed on six international differential wheat genotypes under controlled conditions. Races 1, 5, 6 and 7 were identified with races 5 and 6 being most frequent, representing 47% and 44% of isolates tested, respectively. Only eight isolates (6% collected at two research stations and a farm field near a station in 2014 and 2015 were race 1, while three isolates collected in 2014 in a farm field in north-eastern Morocco were race 7. The uniform race structure in farm fields may be due to overreliance on a limited and narrow genetic base for durum wheat crops in Morocco. However, the identification of four races is significant since P. tritici-repentis can generate new combinations of virulence, thereby increasing race diversity. Combined with the low wheat diversity this may lead to future severe disease epidemics.

    Karima BOUNGAB


    Full Text Available Barley Net Blotch caused by Pyrenophora teres f. teres (Ptt is one of the most important foliar diseases in north western Algeria. The disease could cause appreciable yield losses under favorable environmental conditions. Studies on pathogen variability and distribution of virulence in Ptt are essential to identify effective sources of resistance to net blotch of barley. In this study, pathogenic variability in 48 isolates of Ptt, collected from different barley-growing areas of north-western Algeria were evaluated using 22 barley genotypes as differential hosts. Trials carried out under controlled conditions confirmed the large variation in the virulence of this fungus. The genotypes exhibited variability in response ranging from complete resistance to high susceptibility. This is the first report of pathogenic variability in Ptt in north western Algeria. The 48 isolates tested were further differentiated into 12 pathotypes according to their reaction on the host. Eight differential cultivars were resistant to all isolates tested, but others were susceptible to one or more of the isolates. The variability in the pathogen and the resistance identified in some genotypes used in this study are being investigated further to develop superior, adapted germplasm for use in barley breeding programs in north western Algeria.

  5. Is Pyrenophora semeniperda the cause of downy brome (Bromus tectorum) die-offs? (United States)

    Owen W. Baughman; Susan E. Meyer


    Downy brome (cheatgrass) is a highly successful, exotic, winter annual invader in semi-arid western North America, forming near-monocultures across many landscapes. A frequent but poorly understood phenomenon in these heavily invaded areas is periodic 'die-off' or complete stand failure. The fungal pathogen Pyrenophora semeniperda is abundant in cheatgrass...

  12. Genetic differentiation in Pyrenophora teres f. teres populations from Syria and Tunisia as assessed by AFLP markers. (United States)

    Bouajila, A; Zoghlami, N; Murad, S; Baum, M; Ghorbel, A; Nazari, K


    To investigate the level of genetic differentiation and diversity among Pyrenophora teres isolate populations originating from different agro-ecological areas of Syria and Tunisia and to determine the potential of AFLP profiling in genotyping Pyrenophora teres f. teres. In this study, AFLP markers have been employed to identify patterns of population structure in 20 Pyrenophora teres f. teres populations from Syria and Tunisia. Ninety-four isolates were studied by the use of a protocol that involved stringent PCR amplification of fragments derived from digestion of genomic DNA with restriction enzymes EcoRI and MesI. Based on 401 amplified polymorphic DNA markers (AFLP), variance analyses indicated that most of the variation was partitioned within rather than between populations. Genotypic diversity (GD) was high for populations from Rihane, local landraces and different agro-ecological zones (GD = 0·75-0·86). There was high genetic differentiation among pathogen populations from different host populations in Syria (Gst  = 0·31, ht = 0·190) and Tunisia (Gst  = 0·39, ht = 0·263), which may be partly explained by the low gene flow around the areas sampled. A phenetic tree revealed three groups with high bootstrap values (55, 68, 76) and reflected the grouping of isolates based on host, or agro-ecological areas. AFLP profiling is an effective method for typing the genetically diverse pathogen Pyrenophora teres f. teres. The study represents a comparative analysis of the genetic diversity in P. teres isolates from two countries spanning two continents and also shows that several distinct P. teres genotypes may be found in a given environment. The implications of these findings for Pyrenophora teres f. teres evolutionary potential and net blotch-resistance breeding in Syria and Tunisia were also discussed. © 2012 The Society for Applied Microbiology.

  15. Host-selective toxins of Pyrenophora tritici-repentis induce common responses associated with host susceptibility.

    Directory of Open Access Journals (Sweden)

    Iovanna Pandelova

    Full Text Available Pyrenophora tritici-repentis (Ptr, a necrotrophic fungus and the causal agent of tan spot of wheat, produces one or a combination of host-selective toxins (HSTs necessary for disease development. The two most studied toxins produced by Ptr, Ptr ToxA (ToxA and Ptr ToxB (ToxB, are proteins that cause necrotic or chlorotic symptoms respectively. Investigation of host responses induced by HSTs provides better insight into the nature of the host susceptibility. Microarray analysis of ToxA has provided evidence that it can elicit responses similar to those associated with defense. In order to evaluate whether there are consistent host responses associated with susceptibility, a similar analysis of ToxB-induced changes in the same sensitive cultivar was conducted. Comparative analysis of ToxA- and ToxB-induced transcriptional changes showed that similar groups of genes encoding WRKY transcription factors, RLKs, PRs, components of the phenylpropanoid and jasmonic acid pathways are activated. ROS accumulation and photosystem dysfunction proved to be common mechanism-of-action for these toxins. Despite similarities in defense responses, transcriptional and biochemical responses as well as symptom development occur more rapidly for ToxA compared to ToxB, which could be explained by differences in perception as well as by differences in activation of a specific process, for example, ethylene biosynthesis in ToxA treatment. Results of this study suggest that perception of HSTs will result in activation of defense responses as part of a susceptible interaction and further supports the hypothesis that necrotrophic fungi exploit defense responses in order to induce cell death.

  16. Distribution of races of Pyrenophora tritici-repentis in Algeria and identication of a new virulence type

    Directory of Open Access Journals (Sweden)



    Full Text Available Tan spot, caused by Pyrenophora tritici-repentis, is a foliar disease  of wheat, responsible for high economic losses in several wheat  growing areas in the world. There are eight known races of P. tritici-repentis based on ability to induce necrosis and/or chlorosis on a set of differential cultivars. Fifty five isolates of P. tritici-repentis  originating from diverse wheat growing regions in Algeria were  studied to determine which races are present and to identify new  races. Races 1, 4, 5, 6, 7 and 8 were found and a new virulence pattern was identified. Isolates with this pattern induced necrosis in durum  wheat but failed to induce any disease in the common wheat  genotypes in the differential set.

  17. Comparative virulence of Pyrenophora teres f. teres from Syria and Tunisia and screening for resistance sources in barley: implications for breeding. (United States)

    Bouajila, A; Zoghlami, N; Al Ahmed, M; Baum, M; Ghorbel, A; Nazari, K


    The aim of this study is to investigate the pathogenic diversity and virulence groups among Pyrenophora teres f. teres isolates, sampled from Syria and Tunisia, and to identify the most effective source of resistance in barley that could be used in breeding programmes to control net blotch in both countries. One hundred and four isolates of P. teres f. teres were collected from barley in different agroecological zones of Tunisia and Syria. Their virulence was evaluated using 14 barley genotypes as differential hosts. The UPGMA clustering identified high pathogenic variability; the isolates were clustered onto 20 pathotypes that were sheltered under three virulence groups, with high, intermediate and low disease scores. According to susceptibility/resistance frequencies and mean disease ratings, CI05401 cultivar ranked as the best differential when inoculated with the Syrian isolates. However, CI09214 cultivar was classified as the best effective source of resistance in Tunisia. All P. teres f. teres isolates were differentially pathogenic. CI09214 and CI05401 cultivars were released as the most effective sources of resistance in Syria and Tunisia. National and international barley breeding programmes that seek to develop resistance against P. teres f. teres in barley should strongly benefit from this study. This resistance cannot be achieved without the proper knowledge of the pathogen virulence spectrum and the sources of host resistance. © 2011 The Authors.

  18. Comparative Genomics of a Plant-Pathogenic Fungus, Pyrenophora tritici-repentis, Reveals Transduplication and the Impact of Repeat Elements on Pathogenicity and Population Divergence

    Manning, Viola A.; Pandelova, Iovanna; Dhillon, Braham; Wilhelm, Larry J.; Goodwin, Stephen B.; Berlin, Aaron M.; Figueroa, Melania; Freitag, Michael; Hane, James K.; Henrissat, Bernard; Holman, Wade H.; Kodira, Chinnappa D.; Martin, Joel; Oliver, Richard P.; Robbertse, Barbara; Schackwitz, Wendy; Schwartz, David C.; Spatafora, Joseph W.; Turgeon, B. Gillian; Yandava, Chandri; Young, Sarah; Zhou, Shiguo; Zeng, Qiandong; Grigoriev, Igor V.; Ma, Li-Jun; Ciuffetti, Lynda M.


    Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins (HST), which are recognized by their host in a genotype-specific manner. To better understand the mechanisms that have led to the increase in disease incidence related to this pathogen, we sequenced the genomes of three P. tritici-repentis isolates. A pathogenic isolate that produces two known HSTs was used to assemble a reference nuclear genome of approximately 40 Mb composed of 11 chromosomes that encode 12,141 predicted genes. Comparison of the reference genome with those of a pathogenic isolate that produces a third HST, and a nonpathogenic isolate, showed the nonpathogen genome to be more diverged than those of the two pathogens. Examination of gene-coding regions has provided candidate pathogen-specific proteins and revealed gene families that may play a role in a necrotrophic lifestyle. Analysis of transposable elements suggests that their presence in the genome of pathogenic isolates contributes to the creation of novel genes, effector diversification, possible horizontal gene transfer events, identified copy number variation, and the first example of transduplication by DNA transposable elements in fungi. Overall, comparative analysis of these genomes provides evidence that pathogenicity in this species arose through an influx of transposable elements, which created a genetically flexible landscape that can easily respond to environmental changes.

  19. Reaction of Global Collection of Rye (Secale cereale L. to Tan Spot and Pyrenophora tritici-repentis Races in South Dakota

    Sidrat Abdullah


    Full Text Available Rye (Secale cereale L. serves as an alternative host of Pyrenophora tritici-repentis (PTR the cause of tan spot on wheat. Rye is cultivated as a forage or cover crop and overlaps with a significant portion of wheat acreage in the U.S. northern Great Plains; however, it is not known whether the rye crop influences the evolution of PTR races. We evaluated a global collection of 211 rye accessions against tan spot and assessed the diversity in PTR population on rye in South Dakota. All the rye genotypes were inoculated with PTR races 1 and 5, and infiltrated with Ptr ToxA and Ptr ToxB, at seedling stage. We observed 21% of the genotypes exhibited susceptibility to race 1, whereas, 39% were susceptible to race 5. All 211 accessions were insensitive to both the Ptr toxins. It indicates that though rye exhibits diversity in reaction to tan spot, it lacks Ptr ToxA and ToxB sensitivity genes. This suggests that unknown toxins or other factors can lead to PTR establishment in rye. We characterized the race structure of 103 PTR isolates recovered from rye in South Dakota. Only 22% of the isolates amplified Ptr ToxA gene and were identified as race 1 based on their phenotypic reaction on the differential set. The remaining 80 isolates were noted to be race 4. Our results show that races 1 and 4 are prevalent on rye in South Dakota with a higher frequency of race 4, suggesting a minimal role of rye in the disease epidemiology.

  7. Mortality table construction (United States)



    Mortality tables play important role in actuarial studies such as life annuities, premium determination, premium reserve, valuation pension plan, pension funding. Some known mortality tables are CSO mortality table, Indonesian Mortality Table, Bowers mortality table, Japan Mortality table. For actuary applications some tables are constructed with different environment such as single decrement, double decrement, and multiple decrement. There exist two approaches in mortality table construction : mathematics approach and statistical approach. Distribution model and estimation theory are the statistical concepts that are used in mortality table construction. This article aims to discuss the statistical approach in mortality table construction. The distributional assumptions are uniform death distribution (UDD) and constant force (exponential). Moment estimation and maximum likelihood are used to estimate the mortality parameter. Moment estimation methods are easier to manipulate compared to maximum likelihood estimation (mle). However, the complete mortality data are not used in moment estimation method. Maximum likelihood exploited all available information in mortality estimation. Some mle equations are complicated and solved using numerical methods. The article focus on single decrement estimation using moment and maximum likelihood estimation. Some extension to double decrement will introduced. Simple dataset will be used to illustrated the mortality estimation, and mortality table.

  13. Mortality associated with phaeochromocytoma. (United States)

    Prejbisz, A; Lenders, J W M; Eisenhofer, G; Januszewicz, A


    Two major categories of mortality are distinguished in patients with phaeochromocytoma. First, the effects of excessive circulating catecholamines may result in lethal complications if the disease is not diagnosed and/or treated timely. The second category of mortality is related to development of metastatic disease or other neoplasms. Improvements in disease recognition and diagnosis over the past few decades have reduced mortality from undiagnosed tumours. Nevertheless, many tumours remain unrecognised until they cause severe complications. Death resulting from unrecognised or untreated tumour is caused by cardiovascular complications. There are also numerous drugs and diagnostic or therapeutic manipulations that can cause fatal complications in patients with phaeochromocytoma. Previously it has been reported that operative mortality was as high as 50% in unprepared patients with phaeochromocytoma who were operated and in whom the diagnosis was unsuspected. Today mortality during surgery in medically prepared patients with the tumour is minimal. Phaeochromocytomas may be malignant at presentation or metastases may develop later, but both scenarios are associated with a potentially lethal outcome. Patients with phaeochromocytoma run an increased risk to develop other tumours, resulting in an increased mortality risk compared to the general population. Phaeochromocytoma during pregnancy represents a condition with potentially high maternal and foetal mortality. However, today phaeochromocytoma in pregnancy is recognised earlier and in conjunction with improved medical management, maternal mortality has decreased to less than 5%. © Georg Thieme Verlag KG Stuttgart · New York.

    A commentary on maternal mortality in Texas is provided in response to a 2016 article in Obstetrics & Gynecology by MacDorman et al. While the Texas Department of State Health Services and the Texas Maternal Mortality and Morbidity Task Force agree that maternal mortality increased sharply from 2010 to 2011, the percentage change or the magnitude of the increase in the maternal mortality rate in Texas differs depending on the statistical methods used to compute and display it. Methodologic challenges in identifying maternal death are also discussed, as well as risk factors and causes of maternal death in Texas. Finally, several state efforts currently underway to address maternal mortality in Texas are described. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

  16. Turbine related fish mortality

    International Nuclear Information System (INIS)

    Eicher, G.J.


    A literature review was conducted to assess the factors affecting turbine-related fish mortality. The mechanics of fish passage through a turbine is outlined, and various turbine related stresses are described, including pressure and shear effects, hydraulic head, turbine efficiency, and tailwater level. The methodologies used in determining the effects of fish passage are evaluated. The necessity of adequate controls in each test is noted. It is concluded that mortality is the result of several factors such as hardiness of study fish, fish size, concentrations of dissolved gases, and amounts of cavitation. Comparisons between Francis and Kaplan turbines indicate little difference in percent mortality. 27 refs., 5 figs

    Charles Sheppard


    Full Text Available The scale of the collapse of coral reef communities in 1998 following a warming episode (Wilkinson, 2000 was unprecedented, and took many people by surprise. The Indian Ocean was the worst affected with a coral mortality over 75% in many areas such as the Chagos Archipelago (Sheppard, 1999, Seychelles (Spencer et al., 2000 and Maldives (McClanahan, 2000. Several other locations were affected at least as much, with mortality reaching 100% (to the nearest whole number; this is being compiled by various authors (e.g., CORDIO, in press. For example, in the Arabian Gulf, coral mortality is almost total across many large areas of shallow water (Sheppard, unpublished; D. George and D. John, personal communication. The mortality is patchy of course, depending on currents, location inside or outside lagoons, etc., but it is now possible to swim for over 200 m and see not one remaining living coral or soft coral on some previously rich reefs.

  19. Reducing infant mortality. (United States)

    Johnson, T R


    Public health and social policies at the population level (e.g., oral rehydration therapy and immunization) are responsible for the major reduction in infant mortality worldwide. The gap in infant mortality rates between developing and developed regions is much less than that in maternal mortality rates. This indicates that maternal and child health (MCH) programs and women's health care should be combined. Since 1950, 66% of infant deaths occur in the 1st 28 days, indicating adverse prenatal and intrapartum events (e.g., congenital malformation and birth injuries). Infection, especially pneumonia and diarrhea, and low birth weight are the major causes of infant mortality worldwide. An estimated US$25 billion are needed to secure the resources to control major childhood diseases, reduce malnutrition 50%, reduce child deaths by 4 million/year, provide potable water and sanitation to all communities, provide basic education, and make family planning available to all. This cost for saving children's lives is lower than current expenditures for cigarettes (US$50 billion in Europe/year). Vitamin A supplementation, breast feeding, and prenatal diagnosis of congenital malformations are low-cost strategies that can significantly affect infant well-being and reduce child mortality in many developing countries. The US has a higher infant mortality rate than have other developed countries. The American College of Obstetricians and Gynecologists and the US National Institutes of Health are focusing on prematurity, low birth weight, multiple pregnancy, violence, alcohol abuse, and poverty to reduce infant mortality. Obstetricians should be important members of MCH teams, which also include traditional birth attendants, community health workers, nurses, midwives, and medical officers. We have the financial resources to allocate resources to improve MCH care and to reduce infant mortality.

  20. Mortality in epilepsy. (United States)

    Hitiris, Nikolas; Mohanraj, Rajiv; Norrie, John; Brodie, Martin J


    All studies report an increased mortality risk for people with epilepsy compared with the general population. Population-based studies have demonstrated that the increased mortality is often related to the cause of the epilepsy. Common etiologies include neoplasia, cerebrovascular disease, and pneumonia. Deaths in selected cohorts, such as sudden unexpected death in epilepsy (SUDEP), status epilepticus (SE), suicides, and accidents are more frequently epilepsy-related. SUDEP is a particular cause for concern in younger people, and whether and when SUDEP should be discussed with patients with epilepsy remain problematic issues. Risk factors for SUDEP include generalized tonic-clonic seizures, increased seizure frequency, concomitant learning disability, and antiepileptic drug polypharmacy. The overall incidence of SE may be increasing, although case fatality rates remain constant. Mortality is frequently secondary to acute symptomatic disorders. Poor compliance with treatment in patients with epilepsy accounts for a small proportion of deaths from SE. The incidence of suicide is increased, particularly for individuals with epilepsy and comorbid psychiatric conditions. Late mortality figures in patients undergoing epilepsy surgery vary and are likely to reflect differences in case selection. Future studies of mortality should be prospective and follow agreed guidelines to better quantify risk and causation in individual populations.

  1. Neonatal mortality in Utah. (United States)

    Woolley, F R; Schuman, K L; Lyon, J L


    A cohort study of neonatal mortality (N = 106) in white singleton births (N = 14,486) in Utah for January-June 1975 was conducted. Using membership and activity in the Church of Jesus Christ of Latter-day Saints (LDS or Mormon) as a proxy for parental health practices, i.e., tobacco and alcohol abstinence, differential neonatal mortality rates were calculated. The influence of potential confounding factors was evaluated. Low activity LDS members were found to have an excess risk of neonatal death five times greater than high activity LDS, with an upper bound of a two-sided 95% confidence interval of 7.9. The data consistently indicate a lower neonatal mortality rate for active LDS members. Non-LDS were found to have a lower rate than either medium or low activity LDS.

  7. Sex differentials in mortality. (United States)


    The questions leing considered are whether a higher female than male mortality rate exists in Ceylon, India, and Pakistan, and whether this sex differential can account for the observed high male sex ratios. There is a choice between explaining the recorded masculinity of the Indian population by assuming that the subordinate position of women caused their omission from the census or that it caused their unrecorded death in childhood. The 1951 census report of India states that there is a traditional fondness for male issues in most parts of the country and a corresponding dislike for female children. However, a life table for India applied to the 1951 census gave a higher average female age at death 34.7 years as opposed to 33.5 years for male. Other estimates for India and Pakistan for the period 1951-1961 give 37.8 years for life expectancy for males and 36.98 for females. In 1953 the female death rate in Ceylon was over 80% higher than that of the males in the most reproductive ages, 20-29. In 1963 the female excess mortality at the same ages was still 25%, and in the age group 30-34 almost a 1/3 higher. In India the female death rate at ages 15-44 was 38% higher than that of the males in the 1958-1959 survey and as much as 174% higher in the Khanna rural survey, 1956-1960. In Pakistan a Population growth Estimate experiment conducted during 1962-1965 on a national probability sample has shown that in the ages 15-44 the female death rate was 75% higher than that of the males. High maternal mortality was the major reason. In addition, female mortality among young children over age 1 year was 24% higher in 1965 and 1963. There was little difference between the rates of mortality of the 2 sexes at age 45 and above. Recent trends in Ceylon show considerable improvement in maternal mortality which has reduced by 22% the ratio of female to male mortality at age 15-44. Also the ratio at ages 1-9 fell by 8%. to .1 of a year for every calendar year to 1980.

    Waseem, A.R.; Samad, A.


    The objective of this study was to determine the mortality rate in patients presenting with Necrotizing Fasciitis. This prospective study was conducted at ward 26, JPMC Karachi over a period of two years from March 2001 to Feb 2003. All patients above the age of 12 years diagnosed to be having Necrotizing Fasciitis and admitted through the Accident and emergency department were included in this study. After resuscitation, the patients underwent the emergency exploration and aggressive surgical debridement. Post-operatively, the patients were managed in isolated section of the ward. The patients requiring grafting were referred to plastic surgery unit. The patients were followed up in outpatients department for about two years. Over all, 25 male and 5 female patients fulfilled the inclusion criteria and were included in this study. The common clinical manifestations include redness, swelling, discharging abscess, pain, fever, skin necrosis and foul smelling discharge etc. The most common predisposing factor was Diabetes mellitus whereas the most commonly involved site was perineum. All patients underwent aggressive and extensive surgical debridements. The common additional procedures included Skin grafting, Secondary suturing, Cystostomy and Orchidectomy. Bacteroides and E. coli were the main micro-organisms isolated in this study. Bacteroides was the most common microorganism isolated among the eight patients who died. Necrotizing Fasciitis is a potentially life threatening emergency condition and carries the mortality rate of about 26.6%. The major contributing factors to increase the mortality missed initially diagnosed, old age, diabetes mellitus truncal involvement and late presentation. Anorectal involvement of disease carry worse prognosis. Hyperbaric oxygen therapy and proper use of unprocessed honey reduced the mortality rate. (author)

  11. Deciphering infant mortality (United States)

    Berrut, Sylvie; Pouillard, Violette; Richmond, Peter; Roehner, Bertrand M.


    This paper is about infant mortality. In line with reliability theory, "infant" refers to the time interval following birth during which the mortality (or failure) rate decreases. This definition provides a systems science perspective in which birth constitutes a sudden transition falling within the field of application of the Transient Shock (TS) conjecture put forward in Richmond and Roehner (2016c). This conjecture provides predictions about the timing and shape of the death rate peak. It says that there will be a death rate spike whenever external conditions change abruptly and drastically and also predicts that after a steep rise there will be a much longer hyperbolic relaxation process. These predictions can be tested by considering living organisms for which the transient shock occurs several days after birth. Thus, for fish there are three stages: egg, yolk-sac and young adult phases. The TS conjecture predicts a mortality spike at the end of the yolk-sac phase and this timing is indeed confirmed by observation. Secondly, the hyperbolic nature of the relaxation process can be tested using very accurate Swiss statistics for postnatal death rates spanning the period from one hour immediately after birth through to age 10 years. It turns out that since the 19th century despite a significant and large reduction in infant mortality, the shape of the age-specific death rate has remained basically unchanged. Moreover the hyperbolic pattern observed for humans is also found for small primates as recorded in the archives of zoological gardens. Our overall objective is to identify a series of cases which start from simple systems and move step by step to more complex organisms. The cases discussed here we believe represent initial landmarks in this quest.

    Child and neonatal mortality is a serious problem in Bangladesh. The main objective of this study was to determine the most significant socio-economic factors (covariates) between the years 2011 and 2014 that influences on neonatal and child mortality and to further suggest the plausible policy proposals. We modeled the neonatal and child mortality as categorical dependent variable (alive vs death of the child) while 16 covariates are used as independent variables using χ 2 statistic and multiple logistic regression (MLR) based on maximum likelihood estimate. Using the MLR, for neonatal mortality, diarrhea showed the highest positive coefficient (β = 1.130; P  economic conditions for neonatal mortality. For child mortality, birth order between 2-6 years and 7 and above years showed the highest positive coefficients (β = 1.042; P  economic conditions for child mortality. This study allows policy makers to make appropriate decisions to reduce neonatal and child mortality in Bangladesh. In 2014, mother's age and father's education were also still significant covariates for child mortality. This study allows policy makers to make appropriate decisions to reduce neonatal and child mortality in Bangladesh.

This article reviews the literature on excess early mortality in persons with schizophrenia and suggests reasons for the high mortality...... as well as possible ways to reduce it. Persons with schizophrenia have an exceptionally short life expectancy. High mortality is found in all age groups, resulting in a life expectancy of approximately 20 years below that of the general population.

  18. Mortality, fog and atmospheric pollution

    Energy Technology Data Exchange (ETDEWEB)

    Martin, A E; Bradley, W H


    A study was made associating climate and atmospheric pollution with excess mortality in greater London during the winter of 1958 and 1959. It was a particularly foggy winter with 6 major episodes, 4 of which resembled previous dangerous smogs. There were two additional periods of high pollution without fog. Excess mortality during these 8 periods ranged from 70 to 230. During one period, a flu epidemic accompanied the fog. In 4 to 6 foggy periods, morbidity (hospital bed demand) also increased. This small number of observations indicates mortality association: on 2/3 of days with high SO/sub 2/ (2.5 pphM) or high particulate soot (10 mg/m/sup 3/), and on all days with thick fog, there was an increase in mortality (20 deaths more than previous day) on that or the following day. Fifteen-day moving mortality index and bronchitis mortality index were significantly correlated with black suspended matter and SO/sub 2/; association with pneumonia was not significant. Also little or no relation between mortality and humidity, mean temperature, or barometric pressure was found. Rapid response of mortality to air pollution may indicate that pollution affects mostly those already ill.

    Full Text Available Mortality and longevity risk is usually one of the main risk components ineconomic capital models of insurance companies. Above all, future mortalityexpectations are an important input in the modeling and pricing of long termproducts. Deviations from the expectation can lead insurance company even todefault if sufficient reserves and capital is not held. Thus, Modeling of mortalitytime series accurately is a vital concern for the insurance industry. The aim of thisstudy is to perform distributional and spectral testing to the mortality data andpracticed discrete and continuous time modeling. We believe, the results and thetechniques used in this study will provide a basis for Value at Risk formula incase of mortality.

  9. Cancer mortality in Hanford workers

    International Nuclear Information System (INIS)

    Marks, S.; Gilbert, E.S.; Breitenstein, B.D.


    Personnel and radiation exposure data for past and present employees of the Hanford plant have been collected and analysed for a possible relationship of exposure to mortality. The occurrence of death in workers was established by the Social Security Administration and the cause of death obtained from death certificates. Mortality from all causes, all cancer cases and specific cancer types was related to the population at risk. Standardized mortality ratios were calculated for white males, using age- and calendar year-specific mortality rates for the U.S. population in the calculation of expected deaths. This analysis showed a substantial 'healthy worker effect' and no significantly high standardized mortality ratios for specific disease categories. A test for association of mortality with levels of radiation exposure revealed no correlation for all causes and all cancer. In carrying out this test, adjustment was made for age and calendar year of death, length of employment and occupational category. A statistically significant test for trend was obtained for multiple myeloma and carcinoma of the pancreas. However, in view of the absence of such a correlation for diseases more commonly associated with radiation exposure such as myeloid leukaemia, as well as the small number of deaths in higher exposure groups, the results cannot be considered definitive. Any conclusions based on these associations should be viewed in relation to the results of other studies. These results are compared with those of other investigators who have analysed the Hanford data. (author)

  11. Respiratory tract mortality in cement workers: a proportionate mortality study (United States)


    Background The evidence regarding the association between lung cancer and occupational exposure to cement is controversial. This study investigated causes of deaths from cancer of respiratory tract among cement workers. Methods The deaths of the Greek Cement Workers Compensation Scheme were analyzed covering the period 1969-1998. All respiratory, lung, laryngeal and urinary bladder cancer proportionate mortality were calculated for cement production, maintenance, and office workers in the cement industry. Mortality from urinary bladder cancer was used as an indirect indicator of the confounding effect of smoking. Results Mortality from all respiratory cancer was significantly increased in cement production workers (PMR = 1.91; 95% CI 1.54 to 2.33). The proportionate mortality from lung cancer was significantly elevated (PMR = 2.05; 95% CI 1.65 to 2.52). A statistically significant increase in proportionate mortality due to respiratory (PMR = 1.7; 95% CI 1.2 to 2.34). and lung cancer (PMR = 1.67;95% CI = 1.15-2.34) among maintenance workers has been observed. The PMR among the three groups of workers (production, maintenance, office) did differ significantly for lung cancer (p = 0.001), while the PMR for urinary bladder cancer found to be similar among the three groups of cement workers. Conclusion Cement production, and maintenance workers presented increased lung and respiratory cancer proportionate mortality, and this finding probably cannot be explained by the confounding effect of smoking alone. Further research including use of prospective cohort studies is needed in order to establish a causal association between occupational exposure to cement and risk of lung cancer. PMID:22738120

  13. Universal mortality law and immortality (United States)

    Azbel', Mark Ya.


    Well-protected human and laboratory animal populations with abundant resources are evolutionarily unprecedented. Physical approach, which takes advantage of their extensively quantified mortality, establishes that its dominant fraction yields the exact law, which is universal for all animals from yeast to humans. Singularities of the law demonstrate new kinds of stepwise adaptation. The law proves that universal mortality is an evolutionary by-product, which at any given age is reversible, independent of previous life history, and disposable. Life expectancy may be extended, arguably to immortality, by minor biological amendments in the animals. Indeed, in nematodes with a small number of perturbed genes and tissues it increased 6-fold (to 430 years in human terms), with no apparent loss in health and vitality. The law relates universal mortality to specific processes in cells and their genetic regulation.

In Funen, Denmark, multidisciplinary breast cancer management teams started before screening...... was introduced; both activities came later in the rest of Denmark. Because Denmark had national protocols for breast cancer treatment, but hardly any opportunistic screening, Funen formed a "natural experiment", providing valid comparison groups and enabling the separation of the effect of screening from other...... factors.

The latter was estimated from breast cancer mortality in the rest of Denmark controlled for historical differences between...

  15. Predicting mortality from human faces. (United States)

    Dykiert, Dominika; Bates, Timothy C; Gow, Alan J; Penke, Lars; Starr, John M; Deary, Ian J


    To investigate whether and to what extent mortality is predictable from facial photographs of older people. High-quality facial photographs of 292 members of the Lothian Birth Cohort 1921, taken at the age of about 83 years, were rated in terms of apparent age, health, attractiveness, facial symmetry, intelligence, and well-being by 12 young-adult raters. Cox proportional hazards regression was used to study associations between these ratings and mortality during a 7-year follow-up period. All ratings had adequate reliability. Concurrent validity was found for facial symmetry and intelligence (as determined by correlations with actual measures of fluctuating asymmetry in the faces and Raven Standard Progressive Matrices score, respectively), but not for the other traits. Age as rated from facial photographs, adjusted for sex and chronological age, was a significant predictor of mortality (hazard ratio = 1.36, 95% confidence interval = 1.12-1.65) and remained significant even after controlling for concurrent, objectively measured health and cognitive ability, and the other ratings. Health as rated from facial photographs, adjusted for sex and chronological age, significantly predicted mortality (hazard ratio = 0.81, 95% confidence interval = 0.67-0.99) but not after adjusting for rated age or objectively measured health and cognition. Rated attractiveness, symmetry, intelligence, and well-being were not significantly associated with mortality risk. Rated age of the face is a significant predictor of mortality risk among older people, with predictive value over and above that of objective or rated health status and cognitive ability.

  16. [Adult mortality differentials in Argentina]. (United States)

    Rofman, R


    Adult mortality differentials in Argentina are estimated and analyzed using data from the National Social Security Administration. The study of adult mortality has attracted little attention in developing countries because of the scarcity of reliable statistics and the greater importance assigned to demographic phenomena traditionally associated with development, such as infant mortality and fertility. A sample of 39,421 records of retired persons surviving as of June 30, 1988, was analyzed by age, sex, region of residence, relative amount of pension, and social security fund of membership prior to the consolidation of the system in 1967. The thirteen former funds were grouped into the five categories of government, commerce, industry, self-employed, and other, which were assumed to be proxies for the activity sector in which the individual spent his active life. The sample is not representative of the Argentine population, since it excludes the lowest and highest socioeconomic strata and overrepresents men and urban residents. It is, however, believed to be adequate for explaining mortality differentials for most of the population covered by the social security system. The study methodology was based on the technique of logistic analysis and on the use of regional model life tables developed by Coale and others. To evaluate the effect of the study variables on the probability of dying, a regression model of maximal verisimilitude was estimated. The model relates the logit of the probability of death between ages 65 and 95 to the available explanatory variables, including their possible interactions. Life tables were constructed by sex, region of residence, previous pension fund, and income. As a test of external consistency, a model including only age and sex as explanatory variables was constructed using the methodology. The results confirmed consistency between the estimated values and other published estimates. A significant conclusion of the study was that

    Conclusion: Individual oral health conditions—tooth loss, root caries, and periodontal disease—were not related to mortality when sociodemographic, health, and/or health behavioral factors were considered, and there was no differential pattern between the three conditions. Multiple oral health problems were associated with a higher risk of dying.

  1. [Beer, wine, spirits and mortality]. (United States)

    Grønbaek, M N; Sørensen, T I; Johansen, D; Becker, U; Gottschau, A; Schnohr, P; Hein, H O; Jensen, G


    A population based cohort study investigates the association between alcohol intake and mortality from all causes, coronary heart disease and cancer. The design is prospective with baseline assessment of intake of beer, wine and spirits, smoking habits, educational level, physical activity, and body mass index and a total of 257,859 person-years follow-up on mortality. A total of 4,833 participants died, of these 1,075 from coronary heart disease and 1,552 of cancer. Compared with non-drinkers, light drinkers who avoided wine, had a relative risk of death from all causes of 0.90 (0.82-0.99) and those who drank wine had a relative risk of 0.66 (0.55-0.77). Heavy drinkers who avoided wine were at higher risk of death from all causes than were heavy drinkers who included wine in their alcohol intake. Wine drinkers had significantly lower mortality from both coronary heart disease and cancer than did non-wine drinkers (p = 0.007 and p = 0.004, respectively). In conclusion, wine intake may have a beneficial effect on all cause mortality that is additive to that of alcohol. This effect may be attributable to a reduction in death from both coronary heart disease and cancer.

  2. Manatee mortality in Puerto Rico (United States)

    Mignucci-Giannoni, A. A.; Montoya-Ospina, R. A.; Jimenez-Marrero, N. M.; Rodriguez-Lopez, M.; Williams, E.H.; Bonde, R.K.


    The most pressing problem in the effective management of the West Indian manatee (Trichechus manatus) in Puerto Rico is mortality due to human activities. We assessed 90 cases of manatee strandings in Puerto Rico based on historical data and a coordinated carcass salvage effort from 1990 through 1995. We determined patterns of mortality, including type of event, condition of carcasses, spatial and temporal distribution, gender, size/age class, and the cause of death. The spatial distribution of stranding events was not uniform, with the north, northeast, and south coasts having the highest numbers. Six clusters representing the highest incidence included the areas of Fajardo and Ceiba, Bahia de Jobos, Toa Baja, Guayanilla, Cabo Rojo, and Rio Grande to Luquillo. The number of reported cases has increased at an average rate of 9.6%/yr since 1990. The seasonality of stranding events showed a bimodal pattern, from February through April and in August and September. Most identified causes of death were due to human interaction, especially captures and watercraft collisions. Natural causes usually involved dependent calves. From 1990 through 1995, most deaths were attributed to watercraft collisions. A reduction in anthropogenic mortality of this endangered species can be accomplished only through education and a proactive management and conservation plan that includes law enforcement, mortality assessment, scientific research, rescue and rehabilitation, and inter- and intraagency cooperation.

  4. Mortality among California highway workers. (United States)

    Maizlish, N; Beaumont, J; Singleton, J


    Standardized proportional mortality ratios (PMR) were computed for a population of highway workers. Hazards of highway maintenance work include exposure to solvents, herbicides, asphalt and welding fumes, diesel and auto exhaust, asbestos, abrasive dusts, hazardous material spills, and moving motor vehicles. Underlying cause of death was obtained for 1,570 workers who separated from the California Department of Transportation between 1970 and 1983, and who died in California between 1970 and 1983 (inclusive). Among 1,260 white males, the major findings were statistically significant excesses of cancers of digestive organs (PMR = 128), skin (PMR = 218), lymphopoietic cancer (PMR = 157), benign neoplasms (PMR = 343), motor vehicle accidents (PMR = 141), and suicide (PMR = 154). Black males (N = 66) experienced nonsignificant excesses of cancer of the digestive organs (PMR = 191) and arteriosclerotic heart disease (PMR = 143). Among 168 white females, deaths from lung cancer (PMR = 189) and suicide (PMR = 215) were elevated. White male retirees, a subgroup with 5 or more years of service, experienced excess mortality due to cancers of the colon (PMR = 245), skin (PMR = 738), brain (PMR = 556), and lymphosarcomas and reticulosarcomas (PMR = 514). Deaths from external causes (PMR = 135) and cirrhosis of the liver (PMR = 229) were elevated among white males with a last job in landscape maintenance. White males whose last job was highway maintenance experienced a deficit in mortality from circulatory diseases (PMR = 83) and excess mortality from emphysema (PMR = 250) and motor vehicle accidents (PMR = 196). Further epidemiologic and industrial hygiene studies are needed to confirm the apparent excess mortality and to quantify occupational and nonoccupational exposures. However, reduction of recognized hazards among highway maintenance workers is a prudent precautionary measure.

  5. Lower Mortality in Magnet Hospitals (United States)

    McHugh, Matthew D.; Kelly, Lesly A.; Smith, Herbert L.; Wu, Evan S.; Vanak, Jill M.; Aiken, Linda H.


    Background Although there is evidence that hospitals recognized for nursing excellence—Magnet hospitals—are successful in attracting and retaining nurses, it is uncertain whether Magnet recognition is associated with better patient outcomes than non-Magnets, and if so why. Objectives To determine whether Magnet hospitals have lower risk-adjusted mortality and failure-to-rescue compared with non-Magnet hospitals, and to determine the most likely explanations. Method and Study Design Analysis of linked patient, nurse, and hospital data on 56 Magnet and 508 non-Magnet hospitals. Logistic regression models were used to estimate differences in the odds of mortality and failure-to-rescue for surgical patients treated in Magnet versus non-Magnet hospitals, and to determine the extent to which differences in outcomes can be explained by nursing after accounting for patient and hospital differences. Results Magnet hospitals had significantly better work environments and higher proportions of nurses with bachelor's degrees and specialty certification. These nursing factors explained much of the Magnet hospital effect on patient outcomes. However, patients treated in Magnet hospitals had 14% lower odds of mortality (odds ratio 0.86; 95% confidence interval, 0.76–0.98; P = 0.02) and 12% lower odds of failure-to-rescue (odds ratio 0.88; 95% confidence interval, 0.77–1.01; P = 0.07) while controlling for nursing factors as well as hospital and patient differences. Conclusions The lower mortality we find in Magnet hospitals is largely attributable to measured nursing characteristics but there is a mortality advantage above and beyond what we could measure. Magnet recognition identifies existing quality and stimulates further positive organizational behavior that improves patient outcomes. PMID:24022082

  6. Marital status, health and mortality. (United States)

    Robards, James; Evandrou, Maria; Falkingham, Jane; Vlachantoni, Athina


    Marital status and living arrangements, along with changes in these in mid-life and older ages, have implications for an individual's health and mortality. Literature on health and mortality by marital status has consistently identified that unmarried individuals generally report poorer health and have a higher mortality risk than their married counterparts, with men being particularly affected in this respect. With evidence of increasing changes in partnership and living arrangements in older ages, with rising divorce amongst younger cohorts offsetting the lower risk of widowhood, it is important to consider the implications of such changes for health in later life. Within research which has examined changes in marital status and living arrangements in later life a key distinction has been between work using cross-sectional data and that which has used longitudinal data. In this context, two key debates have been the focus of research; firstly, research pointing to a possible selection of less healthy individuals into singlehood, separation or divorce, while the second debate relates to the extent to which an individual's transitions earlier in the life course in terms of marital status and living arrangements have a differential impact on their health and mortality compared with transitions over shorter time periods. After reviewing the relevant literature, this paper argues that in order to fully account for changes in living arrangements as a determinant of health and mortality transitions, future research will increasingly need to consider a longer perspective and take into account transitions in living arrangements throughout an individual's life course rather than simply focussing at one stage of the life course.

  7. Mortality of Hanford radiation workers

    International Nuclear Information System (INIS)

    Gilbert, E.S.


    Mortality from all causes for white males employed at Hanford for at least two years is 75 percent of that expected on the basis of US vital statistics. Mortality from cancer is 85 percent of that expected. These results are typical of a working population. Neither death from all causes nor death from all cancer types shows a positive correlation with external radiation exposures. Myeloid leukemia, the disease that several studies have found to be associated most strongly with radiation exposure, is not correlated with external radiation exposure of Hanford workers. Two specific cancers, multiple myeloma and to a lesser extent cancer of the pancreas, were found to be positively correlated with radiation exposure. The correlations identified result entirely from a small number of deaths (3 each for multiple myeloma and cancer of the pancreas) with cumulative exposure greater than 15 rem

  9. Physical Inactivity and Mortality Risk

    Directory of Open Access Journals (Sweden)

    Peter Kokkinos


    Full Text Available In recent years a plethora of epidemiologic evidence accumulated supports a strong, independent and inverse, association between physical activity and the fitness status of an individual and mortality in apparently healthy individuals and diseased populations. These health benefits are realized at relatively low fitness levels and increase with higher physical activity patterns or fitness status in a dose-response fashion. The risk reduction is at least in part attributed to the favorable effect of exercise or physical activity on the cardiovascular risk factors, namely, blood pressure, diabetes mellitus and obesity. In this review, we examine evidence from epidemiologic and interventional studies in support of the association between exercise and physical activity and health. In addition, we present the exercise effects on the aforementioned risk factors. Finally, we include select dietary approaches and their impact on risk factors and overall mortality risk.

  10. Population growth and infant mortality


    Fabella, Christina


    The relationship between population growth and economic outcomes is an issue of great policy significance. In the era of the Millennium Development Goals, poverty and its correlates have become the compelling issues. Economic growth may not automatically translate into reductions in poverty and its correlates (may not trickle down) if income distribution is at the same time worsening. We therefore investigate the direct effect of population growth on infant mortality for various income catego...

  11. Mortality of nitrate fertiliser workers. (United States)

    Al-Dabbagh, S; Forman, D; Bryson, D; Stratton, I; Doll, R


    An epidemiological cohort study was conducted to investigate the mortality patterns among a group of workers engaged in the production of nitrate based fertilisers. This study was designed to test the hypothesis that individuals exposed to high concentrations of nitrates might be at increased risk of developing cancers, particularly gastric cancer. A total of 1327 male workers who had been employed in the production of fertilisers between 1946 and 1981 and who had been occupationally exposed to nitrates for at least one year were followed up until 1 March 1981. In total, 304 deaths were observed in this group and these were compared with expected numbers calculated from mortality rates in the northern region of England, where the factory was located. Analysis was also carried out separately for a subgroup of the cohort who had been heavily exposed to nitrates--that is, working in an environment likely to contain more than 10 mg nitrate/m3 for a year or longer. In neither the entire cohort nor the subgroup was any significant excess observed for all causes of mortality or for mortality from any of five broad categories of cause or from four specific types of cancer. A small excess of lung cancer was noted more than 20 years after first exposure in men heavily exposed for more than 10 years. That men were exposed to high concentrations of nitrate was confirmed by comparing concentrations of nitrates in the saliva of a sample of currently employed men with control men, employed at the same factory but not in fertiliser production. The men exposed to nitrate had substantially raised concentrations of nitrate in their saliva compared with both controls within the industry and with men in the general population and resident nearby. The results of this study therefore weight against the idea that exposure to nitrates in the environment leads to the formation in vivo of material amounts of carcinogens. PMID:3015194

  12. Macroeconomic Conditions, Health and Mortality


    Christopher J. Ruhm


    Although health is conventionally believed to deteriorate during macroeconomic downturns, the empirical evidence supporting this view is quite weak and comes from studies containing methodological shortcomings that are difficult to remedy. Recent research that better controls for many sources of omitted variables bias instead suggests that mortality decreases and physical health improves when the economy temporarily weakens. This partially reflects reductions in external sources of death, suc...

    Full Text Available Objective: to report the group's experience with a series of patients undergoing pancreatic resection presenting null mortality rates. Methods: we prospectively studied 50 consecutive patients undergoing pancreatic resections for peri-ampullary or pancreatic diseases. Main local complications were defined according to international criteria. In-hospital mortality was defined as death occurring in the first 90 postoperative days. Results: patients' age ranged between 16 and 90 years (average: 53.3. We found anemia (Hb < 12g/dl and preoperative jaundice in 38% and 40% of cases, respectively. Most patients presented with peri-ampullary tumors (66%. The most common surgical procedure was the Kausch - Whipple operation (70%. Six patients (12% needed to undergo resection of a segment of the mesenteric-portal axis. The mean operative time was 445.1 minutes. Twenty two patients (44% showed no clinical complications and presented mean hospital stay of 10.3 days. The most frequent complications were pancreatic fistula (56%, delayed gastric emptying (17.1% and bleeding (16%. Conclusion : within the last three decades, pancreatic resection is still considered a challenge, especially outside large specialized centers. Nevertheless, even in our country (Brazil, teams seasoned in such procedure can reach low mortality rates.

    Mortality trends in Hungary since the Second World War are analyzed. Two periods are distinguished; the first, from 1946 to 1966, was a period of declining mortality and increasing life expectancy, and the second, from 1966 until the present, a period of rising mortality and declining life expectancy, particularly for males, coupled with relatively stable mortality levels for females. The author analyzes differences in causes of death by age in these two periods. (ANNOTATION)

  9. Asthma mortality in Uruguay, 1984-1998. (United States)

    Baluga, J C; Sueta, A; Ceni, M


    Asthma mortality rates have increased worldwide during the past several years despite the increased availability of new and effective medications. Few studies show reliable data from Latin American countries. To determine asthma mortality rates from 1984 to 1998 and to relate mortality to sales of asthma medications. We conducted a retrospective epidemiologic study in the total population of Uruguay. Data were obtained from the Department of Statistics of the Ministry of Public Health. Trends in mortality rates were analyzed using linear regression procedures. Spearman rank correlations were used to relate mortality rates to sales of asthma medications. The mean overall mortality rate was 5.10 per 100,000 during the period 1984 to 1998, (range 6.08 to 3.39) and showed a decreasing trend (P = 0.001). During the period 1995 to 1998, a more pronounced decrease was observed (mean mortality rate, 4.10 per 100,000). In the 5- to 34-year-old age group the mean mortality rate was 0.43 (range 0.65 to 0.13). Similarly, the mortality rate in this age group decreased particularly in the 1994 to 1998 period (mean 0.19; P = 0.005). Finally, the mortality rate was inversely correlated with sales of inhaled corticosteroids; for the overall mortality rate, p = -0.71, P = 0.003; for 5- to 34-year-old age group, p = -0.63, P = 0.01. Although mortality attributable to asthma seems to be decreasing, the overall mortality rate is still high compared with more economically developed countries. A more pronounced decrease in asthma mortality has been seen in the 5- to 34-year-old group. At present, Uruguay is a Latin American country with a low rate of asthma mortality. This is probably related to the use of new therapies to treat asthma.

  10. Russian mortality beyond vital statistics

    Directory of Open Access Journals (Sweden)


    Full Text Available Analyses of routine data have established that the extreme mortality fluctuations among young and middle-aged men are the most important single component of both temporal changes in Russian life expectancy at birth and in the gap between male and female life expectancy. It is also responsible for the largest share of the life expectancy gap between Russia and other industrialised countries. A case-control study has been used to identify factors associated with mortality among men aged 20 to 55 in the five major cities of the Udmurt Republic in 1998-99. Men dying from external causes and circulatory disease are taken as cases. Matched controls were selected from men of the same age living in the same neighbourhood of residence. Information about characteristics of cases and controls was obtained by interviewing proxies who were family members or friends of the subjects. After exclusion of those deaths for which proxy informant could not be identified, a total of 205 circulatory disease and 333 external cause cases were included together with the same number of controls. Educational level was significantly associated with mortality from circulatory diseases and external causes in a crude analysis. However, this could largely be explained by adjustment for employment, marital status, smoking and alcohol consumption. Smoking was associated with mortality from circulatory disease (crude OR=2.44, 95% CI 1.36-4.36, this effect being slightly attenuated after adjustment for socio-economic factors and alcohol consumption. Unemployment was associated with a large increase in the risk of death from external causes (crude OR=3.63, 95% CI 2.17-6.08, an effect that was still substantial after adjustment for other variables (adjusted OR=2.52, 95% CI 1.43-4.43. A reported history of periods of heavy drinking was linked to both deaths from circulatory disease (crude OR=4.21, 95% CI 2.35-7.55 and external cause mortality (crude OR=2.65, 95% CI 1

  12. Mortality in Patients with Endogenous Cushing's Syndrome. (United States)

    Javanmard, Pedram; Duan, Daisy; Geer, Eliza B


    Cushing's syndrome is associated with increased morbidity and mortality. Cardiovascular events, sepsis, and thromboembolism are the leading causes of mortality. Patient's with Cushing's due to a pituitary adenoma and those with Cushing's due to benign adrenal adenoma have relatively good survival outcomes often mirroring that of the general population. Persistent or recurrent disease is associated with high mortality risk. Ectopic Cushing's syndrome and Cushing's due to adrenocortical carcinoma confer the highest mortality risk among Cushing's etiologies. Prompt diagnosis and treatment, and specific monitoring for and treatment of associated comorbidities are essential to decrease the burden of mortality from Cushing's. Copyright © 2018 Elsevier Inc.

  13. Evaluation of morbidity from mortality. (United States)

    Damiani, P; Massé, H; Aubenque, M


    The authors have attempted to measure morbidity involved in mortality, from French regional statistics of causes of death, for the 1968-1970 period. Particularly, they have estimated prevalence rates (proportion of patients at a given moment) and incidence rates (annual proportion of new patients). These rates have been assessed by sex, and for age groups: 15-44 years, 45-64 years, 65-74 years, 75 years and more, and for 18 leading causes of death, according to the International Classification of Diseases (1965). Statistics of causes of deaths have been corrected to take into account non specified causes of death.

    Palat Rao, Mukund; Davi, Nicole K.; D'Arrigo, Rosanne D.; Skees, Jerry; Nachin, Baatarbileg; Leland, Caroline; Lyon, Bradfield; Wang, Shih-Yu; Byambasuren, Oyunsanaa


    Recent incidences of mass livestock mortality, known as dzud, have called into question the sustainability of pastoral nomadic herding, the cornerstone of Mongolian culture. A total of 20 million head of livestock perished in the mortality events of 2000-2002, and 2009-2010. To mitigate the effects of such events on the lives of herders, international agencies such as the World Bank are taking increasing interest in developing tailored market-based solutions like index-insurance. Their ultimate success depends on understanding the historical context and underlying causes of mortality. In this paper we examine mortality in 21 Mongolian aimags (provinces) between 1955 and 2013 in order to explain its density independent cause(s) related to climate variability. We show that livestock mortality is most strongly linked to winter (November-February) temperatures, with incidences of mass mortality being most likely to occur because of an anomalously cold winter. Additionally, we find prior summer (July-September) drought and precipitation deficit to be important triggers for mortality that intensifies the effect of upcoming winter temperatures on livestock. Our density independent mortality model based on winter temperature, summer drought, summer precipitation, and summer potential evaporanspiration explains 48.4% of the total variability in the mortality dataset. The Mongolian index based livestock insurance program uses a threshold of 6% mortality to trigger payouts. We find that on average for Mongolia, the probability of exceedance of 6% mortality in any given year is 26% over the 59 year period between 1955 and 2013.

  17. Mortality study of lead workers

    Energy Technology Data Exchange (ETDEWEB)

    Cooper, W C; Gaffey, W R


    The mortality of 7,032 men employed for one or more years in lead production facilities or battery plants was followed over a 23-year period, 1947-70. Lead absorption in many of these men was greatly in excess of currently accepted standards based upon urinary and blood lead concentrations available for a portion of the group. There were 1,356 deaths reported. The standardized mortality ratio (SMR) for all causes was 107 for smelter workers and 99 for battery plant workers. Death from neoplasms were in slight excess in smelters, but not significantly increased in battery plants. There were no excess deaths from kidney tumors. The SMR for cardiovascular-renal disease was 96 for smelter workers and 101 for battery plant workers. There was definitely no excess in deaths from either stroke or hypertensive heart disease; however, deaths classified as other hypertensive disease and unspecified nephritis or renal sclerosis were higher than expected. The life expectancy of lead workers was calculated to be approximately the same as that of all U.S. males.

  18. Indirect effects of an invasive annual grass on seed fates of two native perennial grass species. (United States)

    Meyer, Susan E; Merrill, Katherine T; Allen, Phil S; Beckstead, Julie; Norte, Anna S


    Invasive plants exhibit both direct and indirect negative effects on recruitment of natives following invasion. We examined indirect effects of the invader Bromus tectorum (cheatgrass) on seed fates of two native grass species, Elymus elymoides and Pseudoroegneria spicata, by removing B. tectorum and by adding inoculum of the shared seed pathogen Pyrenophora semeniperda in factorial experiments at xeric and mesic field sites. We also included a supplemental watering treatment to increase emergence and also the potential for pathogen escape. We recorded emergence and survival of native seedlings and also determined the fate of unemerged seeds. At the xeric site, Pyrenophora-caused mortality was high (34%), and effects of other pathogens and failed emergence of germinants were smaller. Cheatgrass removal negatively affected both emergence (35 vs. 25%) and spring survival (69 vs. 42%). Pyrenophora-caused seed mortality increased with inoculum augmentation for both species (22 vs. 47% overall), but emergence was negatively impacted only for P. spicata (20 vs. 34%). At the mesic site, Pyrenophora-caused mortality was low (6%). Cheatgrass removal doubled emergence (26 vs. 14%). Seed mortality increased significantly with inoculum augmentation for P. spicata (12 vs. 5%) but not E. elymoides, while emergence was not significantly affected in either species. A large fraction of seeds produced germinants that failed to emerge (37%), while another large fraction (35%) was killed by other pathogens. We conclude that facilitation by cheatgrass at the xeric site but interference at the mesic site was probably mediated through litter effects that could be ameliorative or suppressive. Apparent competition between cheatgrass and native grasses could occur through Pyrenophora, especially in a xeric environment, but effects were weak or absent at emergence. This was probably because Pyrenophora attacks the same slow-germinating fraction that is subject to pre-emergence mortality from

    Genowska, Agnieszka; Jamiołkowski, Jacek; Szpak, Andrzej; Pajak, Andrzej


    The study objective was to evaluate quantitatively the relationship between demographic characteristics, socio-economic status and medical care resources with all cause mortality in Poland. Ecological study was performed using data for the population of 66 subregions of Poland, obtained from the Central Statistical Office of Poland. The information on the determinants of health and all cause mortality covered the period from 1st January 2005 to 31st December 2010. Results for the repeated measures were analyzed using Generalized Estimating Equations GEE model. In the model 16 independent variables describing health determinants were used, including 6 demographic variables, 6 socio-economic variables, 4 medical care variables. The dependent variable, was age standardized all cause mortality rate. There was a large variation in all cause mortality, demographic features, socio-economic characteristics, and medical care resources by subregion. All cause mortality showed weak associations with demographic features, among which only the increased divorce rate was associated with higher mortality rate. Increased education level, salaries, gross domestic product (GDP) per capita, local government expenditures per capita and the number of non-governmental organizations per 10 thousand population was associated with decrease in all cause mortality. The increase of unemployment rate was related with a decrease of all cause mortality. Beneficial relationship between employment of medical staff and mortality was observed. Variation in mortality from all causes in Poland was explained partly by variation in socio-economic determinants and health care resources.

  2. Maternal Mortality – A Challenge?

    Directory of Open Access Journals (Sweden)

    Shital G. Sonone


    Full Text Available Background : The current maternal mortality rate (MMR in Maharashtra is 104/100000 live births, ranking 3rd in India. There is scope for reducing it as majority of the causes of MMR are preventable and curable. Aims and Objectives: To study the sociodemographic profile and causes of maternal deaths at Dr. V. M. Govt. Medical College, Solapur. Material and Methods: The study population included all deliveries i.e. women admitted in the hospital during pregnancy, child-birth or within 42 days of termination of pregnancy from any cause related to or aggravated due to pregnancy during the period of 2 years from 1st August 2009 to 31st July 2011. IPD case records and autopsy reports of all maternal deaths were taken and various variables were studied. The present study is prospective study of maternal mortality conducted in Dept. of Obstetrics and Gynaecology, Dr. V. M. Medical College Solapur. Cases were distributed ac-cording to their age, literacy rate, residence,socioeconomic status, ante-natal care, gestational age, gravida/parity, place of referral, pregnancy outcome, and place of delivery, perinatal outcome and etiological factors. This study also suggests the measures to reduce maternal mortality. Results: The total number of live births during the study period were 13,188 and total number of maternal deaths were 63 and MMR was 477 per 1, 00,000 live births. In the maternal deaths studied, 1/3rd of the women were illiterate, half of the women belonged to urban slum areas and of lower socioeconomic class.1/3rd of the deaths occurred in primigravida,within 24 hrs from admission, 58.73% of the patients were referred from outside. Out of that 86.49% of women were sent from private hospital and died in post partum period, having poor perinatal outcome. Haemorrhage (28.57% and hypertension (12.69% are two direct causes and severe anemia (33.33% is most common in direct cause of maternal death in our study.

  3. Mortality among sulfide ore miners

    Ahlman, K.; Koskela, R.S.; Kuikka, P.; Koponen, M.; Annanmaeki, M.


    Lung cancer mortality was studied during 1965-1985 in Outokumpu township in North Karelia, where an old copper mine was located. Age-specific lung cancer death rates (1968-1985) were higher among the male population of Outokumpu than among the North Karelian male population of the same age excluding the Outokumpu district (p less than .01). Of all 106 persons who died from lung cancer during 1965-1985 in Outokumpu township, 47 were miners of the old mine, 39 of whom had worked there for at least three years and been heavily exposed to radon daughters and silica dust. The study cohort consisted of 597 miners first employed between 1954 and 1973 by a new copper mine and a zinc mine, and employed there for at least 3 years. The period of follow-up was 1954-1986. The number of person-years was 14,782. The total number of deaths was 102; the expected number was 72.8 based on the general male population and 97.8 based on the mortality of the male population of North Karelia. The excess mortality among miners was due mainly to ischemic heart disease (IHD); 44 were observed, the expected number was 22.1, based on the general male population, and the North Karelian expected number was 31.2 (p less than .05). Of the 44 miners who died from IHD, 20 were drillers or chargers exposed to nitroglycerin in dynamite charges, but also to several simultaneous stress factors including PAHs, noise, vibration, heavy work, accident risk, and working alone. Altogether 16 tumors were observed in the cohort. Ten of these were lung cancers, the expected number being 4.3. Miners who had died from lung cancer were 35-64 years old, and had entered mining work between 1954 and 1960. Five of the ten lung cancer cases came from the zinc mine (1.7 expected). Three of them were conductors of diesel-powered ore trains

  4. Data base on animal mortality

    International Nuclear Information System (INIS)

    Jones, T.D.


    A data base on animal mortality has been compiled. The literature on LD 50 and the dose-response function for radiation-induced lethality, reflect several inconsistencies - primarily due to dose assignments and to analytical methods and/or mathematical models used. Thus, in order to make the individual experiments which were included in the data base as consistent as possible, an estimate of the uniform dose received by the bone marrow in each treatment group was made so that the interspecies differences are minimized. The LD 50 was recalculated using a single estimation procedure for all studies for which sufficient experimental data are available. For small animals such as mice, the dose to the hematopoietic system is approximately equal to the treatment dose, but for large animals the marrow dose may be about half of the treatment dose

  5. Cancer mortality around nuclear sites

    International Nuclear Information System (INIS)

    Hill, C.; LaPlanche, A.


    Studies (including that of Gardner) of cancer mortality around individual nuclear sites in Britain show an excess of childhood leukemia near such sites. These have been attributed to radioactive discharges, increased radiation doses and radiation doses to the fathers of affected children. However, no such excess has been found in studies in other countries including France, Canada and the USA where similar radiation doses could have been received. Several explanations of this discrepancy are reviewed. It is possible that results from the small UK samples may be due to chance. A difference in external and internal doses for reprocessing plant workers may also be a factor. The possibility of a viral infection for leukemia spreading in new town populations is also mentioned. Whilst the studies in other countries are reassuring, the childhood leukemia excesses found in Britain round nuclear sites are still unexplained. (UK)

  6. Maternal mortality following caesarean sections. (United States)

    Sikdar, K; Kundu, S; Mandal, G S


    A study of 26 maternal deaths following 3647 caesarean sections was conducted in Eden Hospital from 1974-1977. During the time period there were 35,544 births and 308 total maternal deaths (8.74/1000). Indications for Caesarean sections included: 1) abnormal presentation; 2) cephalopelvic disproportion; 3) toxemia; 4) prolonged labor; 5) fetal distress; and 6) post-caesarean pregnancies. Highest mortality rates were among cephalopelvic disproportion, toxemia, and prolonged labor patients. 38.4% of the patients died due to septicaemia and peritonitis, but other deaths were due to preclampsia, shock, and hemorrhage. Proper antenatal care may have prevented anemia and preclampsia and treated other pre-existing or superimposed diseases.

  7. Air pollution and human mortality

    Lave, L B [Carnegie-Mellon Univ., Pittsburgh, PA (USA). Dept. of Economics; Seskin, E P [Department of Commerce, Washington, DC (USA). Environmental and Nonmarket Economics Div.


    Investigations have been made on the quantitative relationship between air pollution and human mortality. While primary focus has been on suspended particulates and sulfates from stationary sources of pollution, the evidence relating to air pollutants attributed to mobile sources was also examined. Using statistical analyses for a large number of US metropolitan areas, it was concluded that the benefits associated with a substantial abatement of air pollution from stationary sources are greater than the costs of such abatement. In contrast, the situation for mobile sources-chiefly cars and trucks is less clear-cut. That is, the costs of implementing the currently mandated US standards for automobile emissions probably exeed their potential health benefits.

    Wood, R.; Smith, N.D.


    A report is given of a cancer mortality study in Caithness, Sutherland, Orkney and Shetland between 1958 and 1982. For Caithness and Sutherland, the numbers of male deaths from all kinds of cancer was significantly less than the numbers expected from figures for Scotland as a whole; for females no difference was observed; the parish of Latheron showed an excess of leukaemia cases. For Orkney and Shetland, the total number of cancer deaths for both sexes was significantly less than for Scotland as a whole. In Shetland, there was an excess of lymphatic leukaemia in Northmaven based on four deaths observed. In Orkney, one parish showed an excess of lymphatic and haematopoietic cancers. (UK)

  9. Maternal mortality: a global overview. (United States)

    Choolani, M; Ratnam, S S


    Reduction of maternal mortality in developing countries is possible through elimination of unsafe abortion, active management of labor, appropriate management of pregnancy complications, and availability of adequate facilities. Prevention and early recognition are key factors in preventing maternal deaths due to ruptured uteri. A well equipped hospital is the appropriate place for delivery of mothers with a history of previous cesarean sections, a grossly contracted pelvis, previous myomectomies, previous multiple births, and previous abnormal births or complications during delivery. Complicated procedures, use of oxytocins, and administration of anesthesia should be performed with experienced, trained medical personnel. Surveillance of and correction for anemia should occur during the course of the pregnancy. Infections can be controlled with tetanus toxoid immunization and use of chest X-rays. The health care system should be tiered with primary health care services located in suburbs and rural districts. Services should be situated to account for population distribution, extent of maternal mortality in the region, transportation facilities, and the nearest secondary hospital. Birthing homes with sanitary facilities are an option for rural districts. A two-way referral system should be established between the primary, secondary, and tertiary level hospitals. Audits should be conducted as a means of checking for needed improvements in the system. Planning that includes proper roads, transportation, and communication facilities is important. Funding can come in the form of money, materials, and manpower. Safe motherhood requires the commitment of local people and local governments. The first step in a safe motherhood program is creating awareness among the political and economic elite. Governments are encouraged to shift resources from the military to housing, transportation, communications, education, and health during peace-times. Local professional associations

In conclusion, hyperprolactinemia was associated with increased...

  16. [Mortality in the perinatal period]. (United States)

    Gutiérrez Avila, J H; Villalobos Olivas, A; Contreras Lemus, J


    A comparative study was conducted between 1978-79 in the pediatric department of the Mexican General Hospital to investigate social and physiopathological conditions leading to neonatal mortality. 100 newborn infants who had survived the first week of life were compared to 100 who had died. Social variables such as maternal age, education, socioeconomic status, marital status, and prenatal care were investigated, as well as physiopathological characteristics such as toxemia, length of gestation, diabetes, bleeding during the last trimester of pregnancy, type of presentation at delivery, congenital malformations, length of delivery, fetal cardiac frequency, and Apgar scores. Considerable social risk factors were identified in unmarried mothers (45.2% of those whose babies died, as compared to 21.4% in the control group), and lack of prenatal care (73.7% versus 41.1%). Physiopathological risk factors were low birth weight (80.5% versus 22%), probable diabetes of the mother (57.3% versus 8.7%), gestation of less than 37 weeks (70.4% versus 17.7%), low Apgar scores at 5 minutes of life (71.0% versus 10.3%), and fetal bradycardia (68.3% versus 6.3% in the control group). Abdominal or cesarean delivery seemed to represent a lesser risk than the use of forceps or the need for manual maneuvers. The need for comprehensive prenatal care programs, especially among the economically poor, is stressed.

  6. Assessment of sampling mortality of larval fishes

    International Nuclear Information System (INIS)

    Cada, G.F.; Hergenrader, G.L.


    A study was initiated to assess the mortality of larval fishes that were entrained in the condenser cooling systems of two nuclear power plants on the Missouri River in Nebraska. High mortalities were observed not only in the discharge collections but also in control samples taken upriver from the plants where no entrainment effects were possible. As a result, entrainment mortality generally could not be demonstrated. A technique was developed which indicated that (1) a significant portion of the observed mortality above the power plants was the result of net-induced sampling mortality, and (2) a direct relationship existed between observed mortality and water velocity in the nets when sampling at the control sites, which was described by linear regression equations. When these equations were subsequently used to remove the effects of wide differences in sampling velocities between control and discharge collections, significant entrainment mortality was noted in all cases. The equations were also used to derive estimates of the natural mortality of ichthyoplankton in this portion of the Missouri River

    Garau, M.; Alonso, R.; Musetti, C.; Barrios, E.


    Objective: To analyze trends in cancer mortality in Uruguay in the period 1989-2008. Methodology: The National Cancer Registry (NCR) collects information from cancer mortality from the death certificates: 147 631 deaths were identified in the period from cancer, which was recorded topography, sex and age. They were calculated for each year mortality rates adjusted for age (TMAE) using as standard the world population. Trends were assessed using the method and calculated the joinpoint Estimated Annual Percent Change (ESPP). Results: The TMAE presents downward trend in both sexes (ESPP = significant -0.60 in men and -0.49 In women). In the period studied, mortality presented decreasing trend when it comes to cancer breast cancer in women (ESPP -0.79, significant), and increased for prostate cancer (ESPP = 0.70) and kidney (ESPP = 1.82 and 1.71 in men and women respectively). As regards the digestive system decreased mortality observed for esophageal cancer (ESPP in = -1.93 men and women = -1.78) and stomach (ESPP = -2.22 men and women -2.24 ). Mortality for cancer of colorectum is stable in men (ESPP = 0.35 No significant (NS)) and shows a decline slight but steady in women (ESPP -0.5). As for cancers that show strong association with smoking, decreased mortality observed lung and laryngeal cancer in men (ESPP = -1.11 and -2.05 respectively), confirming the trend found between 1990 and 2001; in women there is increased mortality from lung cancer (ESPP = 2.76) that is not accompanied by increased mortality from laryngeal cancer (-0.1 ESPP = NS). Mortality from cancers oral cavity and pharynx is stable, but in women a significant increase (ESPP = 1.84) is observed when the oral cavity is analyzed in isolation (lip, tongue, gums, palate). As cervical cancer, mortality trends in 20 years is to increase (ESPP = 1.14), however, if consider only the past decade, mortality appears stabilized (ESPP = 0.57 NS). Conclusions: The overall trend of cancer mortality (all sites

  13. Long-term mortality after poliomyelitis

    DEFF Research Database (Denmark)

    Nielsen, Nete Munk; Rostgaard, Klaus; Juel, Knud


    BACKGROUND: Few studies have described mortality and cause of death among persons with a history of polio. METHODS: We identified a group of patients diagnosed with poliomyelitis in Copenhagen between 1919 and 1954. We obtained information on vital status through May 1997 and on cause of death...... by linkage with the Danish Civil Registration System and the Danish Cause-of-Death Register. Overall and cause-specific standardized mortality ratios served as the measure of mortality risk relative to that of the general population. RESULTS: We observed 1295 deaths among 5977 polio patients compared...... with an expected 1141 deaths (standardized mortality ratio = 1.14; 95% confidence interval = 1.07-1.20). Excess mortality was restricted to polio patients with a history of severe paralysis of the extremities (1.69; 1.32-2.15) or patients who had been treated for respiratory failure during the epidemics (2.71; 2...

This joint lifetable shows a remarkable regularity in the gestational age profile of fetal- and infant mortality: Mortality rates are declining over the whole observed age range with the exception......In order to check hypotheses about the cause for "ontogenescense" -- the phenomenon of a declining force of mortality prior to maturity -- I analyse data on human mortality by gestational age. Based on extensive microdata on births, fetal- and infant deaths in the US 2009 I calculate a joint fetal...... of a "birth hump" peaking week 38. The absolute rate of decline slows down over age. The observed gestational age pattern of the force of mortality is consistent with three hypotheses concerning the causes for ontogenescense: 1) Adaptation: as the organism growths it becomes more resilient towards death, 2...

  15. Vitamin D with calcium reduces mortality

    DEFF Research Database (Denmark)

    Rejnmark, Lars; Avenell, Alison; Masud, Tahir


    Introduction: Vitamin D may affect multiple health outcomes. If so, an effect on mortality is to be expected. Using pooled data from randomized controlled trials, we performed individual patient data (IPD) and trial level meta-analyses to assess mortality among participants randomized to either...... vitamin D alone or vitamin D with calcium. Subjects and Methods: Through a systematic literature search, we identified 24 randomized controlled trials reporting data on mortality in which vitamin D was given either alone or with calcium. From a total of 13 trials with more than 1000 participants each......,528 randomized participants (86.8% females) with a median age of 70 (interquartile range, 62-77) yr. Vitamin D with or without calcium reduced mortality by 7% [hazard ratio, 0.93; 95% confidence interval (CI), 0.88-0.99]. However, vitamin D alone did not affect mortality, but risk of death was reduced if vitamin...

  17. Patterns of mortality rates in Darfur conflict. (United States)

    Degomme, Olivier; Guha-Sapir, Debarati


    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.

  18. Cardiovascular disease mortality in Asian Americans. (United States)

    Jose, Powell O; Frank, Ariel T H; Kapphahn, Kristopher I; Goldstein, Benjamin A; Eggleston, Karen; Hastings, Katherine G; Cullen, Mark R; Palaniappan, Latha P


    Asian Americans are a rapidly growing racial/ethnic group in the United States. Our current understanding of Asian-American cardiovascular disease mortality patterns is distorted by the aggregation of distinct subgroups. The purpose of the study was to examine heart disease and stroke mortality rates in Asian-American subgroups to determine racial/ethnic differences in cardiovascular disease mortality within the United States. We examined heart disease and stroke mortality rates for the 6 largest Asian-American subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) from 2003 to 2010. U.S. death records were used to identify race/ethnicity and cause of death by International Classification of Diseases-10th revision coding. Using both U.S. Census data and death record data, standardized mortality ratios (SMRs), relative SMRs (rSMRs), and proportional mortality ratios were calculated for each sex and ethnic group relative to non-Hispanic whites (NHWs). In this study, 10,442,034 death records were examined. Whereas NHW men and women had the highest overall mortality rates, Asian Indian men and women and Filipino men had greater proportionate mortality burden from ischemic heart disease. The proportionate mortality burden of hypertensive heart disease and cerebrovascular disease, especially hemorrhagic stroke, was higher in every Asian-American subgroup compared with NHWs. The heterogeneity in cardiovascular disease mortality patterns among diverse Asian-American subgroups calls attention to the need for more research to help direct more specific treatment and prevention efforts, in particular with hypertension and stroke, to reduce health disparities for this growing population.

  19. [Maternal mortality: the demographic aspects]. (United States)

    Sanogo, D


    The World Health Organization (WHO) has defined maternal mortality (MM) as a death following a delivery or during the 42 day period following a prolonged or complicated delivery. This definition is ambiguous because it does not take into account the institutional causes (deficiencies) that lead to MM in Sub-Saharan Africa (SSA) nor does it reflect all the reasons leading to MM because of the lack of nationwide health information systems and the lack of accurate statistics. While developed countries can depend on the state to provide accurate statistics, developing countries depend on hospitals, health training centers and special surveys to provide such data which often leads to 25-50% gross underestimations of MM. The most recent WHO data (1989) shows that SSA has the highest MM rates worldwide, ranging from 500- 700/100,000 as compared to Asia with 55-650; Latin America with 110-210 and the developed countries with 10-48. The data for SSA doesn't reflect the true situation in the rural areas where MM rates are over 1000/1000,000. MM is a symptom of poor countries where women contribute to their own deaths through repeated pregnancies, causing significant socioeconomic losses to society. UNICEF (1988) has categorized the demographic factors as high risk for women based on: 1) the age of the mother, and 2) the number of pregnancies. Family planning (FP) reduces MM by preventing illegal abortions; it reduces the number of unwanted pregnancies and increases the earnings of a community by reducing the number of pregnant women. The experience of developed countries demonstrates how women have avoided high-risk and unwanted pregnancies.

  20. Divergent mortality trends by ethnicity in Fiji. (United States)

    Taylor, Richard; Carter, Karen; Naidu, Shivnay; Linhart, Christine; Azim, Syed; Rao, Chalapati; Lopez, Alan D


    To examine trends in infant mortality rate (IMR), adult mortality and life expectancy (LE) in the two major Fijian ethnic groups since 1975. Estimates of IMR, adult mortality (15-59 years) and LE by ethnicity are calculated from previously unreported Fiji Ministry of Health data and extracted from published sources. Over 1975-2008: IMR decreased from 33 to 20 deaths/1,000 live births in i-Taukei (Fiji Melanesians); and 38 to 18 in Fijians of Indian descent. Increased adult male mortality among i-Taukei and decline among Fijians of Indian descent led to an equal probability of dying in 2007 of 29%; while in female adults the probability trended upwards in i-Taukei to 25%, and declined in Fijians of Indian descent to 17%. Life expectancy in both ethnicities increased until 1985 (to 64 years for males; 68 for females) then forming a plateau in males of both ethnicities, and Fijian females of Indian descent, but declining in i-Taukei females to 66 years in 2007. Despite IMR declines over 1975-2008, LE for i-Taukei and Fijians of Indian descent has not increased since 1985, and has actually decreased in i-Taukei women, consistent with trends in adult mortality (15-59 years). Mortality analyses in Fiji that consider the entire population mask divergent trends in the major ethnic groups. This situation is most likely a consequence of non-communicable disease mortality, requiring further assessment and a strengthened response.

  1. [Mortality cost of smoking in Spain]. (United States)

    Cobacho Tornel, Ma Belén; López Nicolás, Angel; Ramos Parreño, José María


    Public policies are crucial for smoking prevention and improving health among the population. Despite the positive impact in Spain of the law for smoking prevention in 2006, there is room for further improvement in this area of public policy. The estimate of the mortality cost per pack of cigarretes is a crucial factor in cost-benefit analysis for policies aimed to reducing smoking induced mortality. The aim of this paper is twofold. First, we estimate the Value of Statistical Life (VSL) among Spanish smokers. Secondly, we quantify the mortality cost of smoking. We use a hedonic wage model to quantify the marginal value of an increase in the mortality risk in monetary terms. We estimate the model for the Spanish labour market using the European Community Household Data and the Encuesta de Accidentes de Trabajo from the Ministerio de Trabajo e Inmigración. We estimate a VSL of 3.78 million Euros for Spanish smokers. Using this value, in conjunction with the increase in the mortality risk over the life cycle due to smoking, the private mortality cost of smoking is 78 Euros per pack for men, and 54 Euros per pack for women (in 2000 Euros). The mortality cost per pack of cigarettes is highly above its market price.

  2. Dengue mortality in Colombia, 1985-2012. (United States)

    Chaparro-Narváez, Pablo; León-Quevedo, Willian; Castañeda-Orjuela, Carlos Andrés


    Dengue in Colombia is an important public health problem due to the huge economic and social costs it has caused, especially during the disease outbreaks.  To describe the behavior of dengue mortality in Colombia between 1985 and 2012.  We conducted a descriptive study. Information was obtained from mortality and population projection databases provided by the Departamento Administrativo Nacional de Estadística (DANE) for the 1985-2012 period. Mortality rates, rate ratios, and case fatality rates were estimated.  A total of 1,990 dengue deaths were registered during this period in Colombia. Dengue mortality rates presented an increasing trend with statistical significance between 1985 and 1998. Higher mortality rates were reported in men both younger than 5 years and older than 65 years. Between 1995 and 2012, category 1 to 4 municipalities reported the highest mortality rates. Case fatality rates varied during the period between 0.01% and 0.39%.  Dengue is an avoidable disease that should disappear from mortality statistics as a cause of death. The event is avoidable if the proposed activities from the Estrategia de Gestión Integrada (EGI)-Dengue are implemented and evaluated. We recommend encouraging the development of an informational culture to contribute to decision making and prioritizing resource allocation.

  3. Ovarian cancer mortality and industrial pollution

    García-Pérez, Javier; Lope, Virginia; López-Abente, Gonzalo; González-Sánchez, Mario


    We investigated whether there might be excess ovarian cancer mortality among women residing near Spanish industries, according to different categories of industrial groups and toxic substances. An ecologic study was designed to examine ovarian cancer mortality at a municipal level (period 1997–2006). Population exposure to pollution was estimated by means of distance from town to facility. Using Poisson regression models, we assessed the relative risk of dying from ovarian cancer in zones around installations, and analyzed the effect of industrial groups and pollutant substances. Excess ovarian cancer mortality was detected in the vicinity of all sectors combined, and, principally, near refineries, fertilizers plants, glass production, paper production, food/beverage sector, waste treatment plants, pharmaceutical industry and ceramic. Insofar as substances were concerned, statistically significant associations were observed for installations releasing metals and polycyclic aromatic chemicals. These results support that residing near industries could be a risk factor for ovarian cancer mortality. - Highlights: • We studied excess mortality due to ovarian cancer near Spanish industries. • Integrated nested Laplace approximations were used as a Bayesian inference tool. • We found excess ovarian cancer mortality near all industrial groups as a whole. • Risk also was found in towns near industries releasing carcinogens and metals. • Risk was associated with plants releasing polycyclic aromatic chemicals and POPs. - Our results support that residing in the vicinity of pollutant industries could be a risk factor for ovarian cancer mortality

  4. Conifer Decline and Mortality in Siberia (United States)

    Kharuk, V.; Im, S.; Ranson, K.


    "Dark needle conifer" (DNC: Abies sibirica, Pinus sibirica and Picea obovata) decline and mortality increase were documented in Russia during recent decades. Here we analyzed causes and scale of Siberian pine and fir mortality in Altai-Sayan and Baikal Lake Regions and West Siberian Plane based on in situdata and remote sensing (QuickBird, Landsat, GRACE). Geographically, mortality began on the margins of the DNC range (i.e., within the forest-steppe and conifer-broadleaf ecotones) and on terrain features with maximal water stress risk (narrow-shaped hilltops, convex steep south facing slopes, shallow well-drained soils). Within ridges, mortality occurred mainly along mountain passes, where stands faced drying winds. Regularly mortality was observed to decrease with elevation increase with the exception of Baikal Lake Mountains, where it was minimal near the lake shore and increased with elevation (up to about 1000 m a.s.l.). Siberian pine and fir mortality followed a drying trend with consecutive droughts since the 1980s. Dendrochronology analysis showed that mortality was correlated with vapor pressure deficit increase, drought index, soil moisture decrease and occurrence of late frosts. In Baikal region Siberian pine mortality correlated with Baikal watershed meteorological variables. An impact of previous year climate conditions on the current growth was found (r2 = 0.6). Thus, water-stressed trees became sensitive to bark beetles and fungi impact (including Polygraphus proximus and Heterobasidion annosum). At present, an increase in mortality is observed within the majority of DNC range. Results obtained also showed a primary role of water stress in that phenomenon with a secondary role of bark beetles and fungi attacks. In future climate with increased drought severity and frequency Siberian pine and fir will partly disappear from its current range, and will be substituted by drought-tolerant species (e.g., Pinus silvestris, Larix sibirica).

  5. Old age mortality and macroeconomic cycles. (United States)

    Rolden, Herbert J A; van Bodegom, David; van den Hout, Wilbert B; Westendorp, Rudi G J


    As mortality is more and more concentrated at old age, it becomes critical to identify the determinants of old age mortality. It has counter-intuitively been found that mortality rates at all ages are higher during short-term increases in economic growth. Work-stress is found to be a contributing factor to this association, but cannot explain the association for the older, retired population. Historical figures of gross domestic product (Angus Maddison) were compared with mortality rates (Human Mortality Database) of middle aged (40-44 years) and older people (70-74 years) in 19 developed countries for the period 1950-2008. Regressions were performed on the de-trended data, accounting for autocorrelation and aggregated using random effects models. Most countries show pro-cyclical associations between the economy and mortality, especially with regard to male mortality rates. On average, for every 1% increase in gross domestic product, mortality increases with 0.36% for 70-year-old to 74-year-old men (p<0.001) and 0.38% for 40-year-old to 44-year-old men (p<0.001). The effect for women is 0.18% for 70-year-olds to 74-year-olds (p=0.012) and 0.15% for 40-year-olds to 44-year-olds (p=0.118). In developed countries, mortality rates increase during upward cycles in the economy, and decrease during downward cycles. This effect is similar for the older and middle-aged population. Traditional explanations as work-stress and traffic accidents cannot explain our findings. Lower levels of social support and informal care by the working population during good economic times can play an important role, but this remains to be formally investigated.

    Full Text Available A cross sectional study was conducted in eight selected villages of Meerut District [UJP.} to find out infant mortality rate alongwith other various health care delivery practices associated with this. An infant mortality rate of 106.7/1000 LB was found in the study population. Infant mortality was higher in female infants, infants of mothers not availed antenatal care, not received tetanus toxoid, delivered by untrained personnel and where cow-dung was applied to cord stump. Among the causes of infant deaths prematurity or low birth weight was the commonest cause followed by respiratory infections, diarrhoeal diseases and tetanus neonatorum

  10. Estimating mortality due to cigarette smoking

    DEFF Research Database (Denmark)

    Brønnum-Hansen, H; Juel, K


    We estimated the mortality from various diseases caused by cigarette smoking using two methods and compared the results. In one method, the "Prevent" model is used to simulate the effect on mortality of the prevalence of cigarette smoking derived retrospectively. The other method, suggested by R....... Peto et al (Lancet 1992;339:1268-1278), requires data on mortality from lung cancer among people who have never smoked and among smokers, but it does not require data on the prevalence of smoking. In the Prevent model, 33% of deaths among men and 23% of those among women in 1993 from lung cancer...... are small and appear to be explicable. The Prevent model can be used for more general scenarios of effective health promotion, but it requires more data than the Peto et al method, which can be used only to estimate mortality related to smoking....

  15. On hunger and child mortality in India. (United States)

    Gaiha, Raghav; Kulkarni, Vani S; Pandey, Manoj K; Imai, Katsushi S


    Despite accelerated growth there is pervasive hunger, child undernutrition and mortality in India. Our analysis focuses on their determinants. Raising living standards alone will not reduce hunger and undernutrition. Reduction of rural/urban disparities, income inequality, consumer price stabilization, and mothers’ literacy all have roles of varying importance in different nutrition indicators. Somewhat surprisingly, public distribution system (PDS) do not have a significant effect on any of them. Generally, child undernutrition and mortality rise with poverty. Our analysis confirms that media exposure triggers public action, and helps avert child undernutrition and mortality. Drastic reduction of economic inequality is in fact key to averting child mortality, conditional upon a drastic reordering of social and economic arrangements.

  18. Mortality impact of extreme winter temperatures (United States)

    Díaz, Julio; García, Ricardo; López, César; Linares, Cristina; Tobías, Aurelio; Prieto, Luis


    During the last few years great attention has been paid to the evaluation of the impact of extreme temperatures on human health. This paper examines the effect of extreme winter temperature on mortality in Madrid for people older than 65, using ARIMA and GAM models. Data correspond to 1,815 winter days over the period 1986 1997, during which time a total of 133,000 deaths occurred. The daily maximum temperature (Tmax) was shown to be the best thermal indicator of the impact of climate on mortality. When total mortality was considered, the maximum impact occured 7 8 days after a temperature extreme; for circulatory diseases the lag was between 7 and 14 days. When respiratory causes were considered, two mortality peaks were evident at 4 5 and 11 days. When the impact of winter extreme temperatures was compared with that associated with summer extremes, it was found to occur over a longer term, and appeared to be more indirect.

    Conclusions: In this series of burn children age ≤ 4 years, Garces index score 4, colistin use in documented multiresistant infections, mechanical ventilation and graft requirement were identified as independent variables related with mortality.

  3. Tempo effects in mortality: An appraisal

    Directory of Open Access Journals (Sweden)

    Michel Guillot


    Full Text Available This study examines the existence of tempo effects in mortality and evaluates the procedure developed by Bongaarts and Feeney for calculating a tempo-adjusted life expectancy. It is shown that Bongaarts and Feeney's index can be interpreted as an indicator reflecting current mortality conditions under specific assumptions regarding the effects of changing period mortality conditions on the timing of future cohort deaths. It is argued, however, that currently there is no clear evidence about the existence of such effects in actual populations. This paper concludes that until the existence of these effects can be demonstrated, it is preferable to continue using the conventional life expectancy as an indicator of current mortality conditions.

    DEFF Research Database (Denmark)

    Thvilum, Marianne; Brandt, Frans; Pedersen, Dorthe Almind


    Background: Although hypothyroidism is associated with increased morbidity, an association with increased mortality is still debated. Our objective was to investigate, at a nationwide level, whether a diagnosis of hypothyroidism influences mortality. Methods: In an observational cohort study from...... January 1, 1978 until December 31, 2008 using record-linkage data from nationwide Danish health registers, 3587 singletons and 682 twins diagnosed with hypothyroidism were identified. Hypothyroid individuals were matched 1:4 with nonhypothyroid controls with respect to age and gender and followed over...... a mean period of 5.6 years (range 0-30 years). The hazard ratio (HR) for mortality was calculated using Cox regression analyses. Comorbidity was evaluated using the Charlson score (CS). Results: In singletons with hypothyroidism, the mortality risk was increased (HR 1.52; 95% confidence interval [CI]: 1...

  7. Increased mortality among people with anxiety disorders

    DEFF Research Database (Denmark)

    Meier, Sandra M; Mattheisen, Manuel; Mors, Ole


    BACKGROUND: Anxiety disorders and depression are the most common mental disorders worldwide and have a striking impact on global disease burden. Although depression has consistently been found to increase mortality; the role of anxiety disorders in predicting mortality risk is unclear. AIMS......: To assess mortality risk in people with anxiety disorders. METHOD: We used nationwide Danish register data to conduct a prospective cohort study with over 30 million person-years of follow-up. RESULTS: In total, 1066 (2.1%) people with anxiety disorders died during an average follow-up of 9.7 years....... The risk of death by natural and unnatural causes was significantly higher among individuals with anxiety disorders (natural mortality rate ratio (MRR) = 1.39, 95% CI 1.28-1.51; unnatural MRR = 2.46, 95% CI 2.20-2.73) compared with the general population. Of those who died from unnatural causes, 16.5% had...

    Two studies dealing with leukaemia in Bavaria/FRG are presented: a mortality study (1972-1978) and a morbidity study (1976-1981). Both were conducted as ecological studies, i.e. under inclusion of environmental factors. Major point of view is first the amount of natural background radiation and second the sites of nuclear reactors, which are six. Mortality and incidence is described. Calculations were made on the influence of migration on patterns of regional distribution. (author)

  11. Mortality in babies with achondroplasia: revisited. (United States)

    Simmons, Kristen; Hashmi, S Shahrukh; Scheuerle, Angela; Canfield, Mark; Hecht, Jacqueline T


    Natural history studies performed 30 years ago identifying higher mortality among children born with achondroplasia, a genetic dwarfing condition, resulted in clinical recommendations aimed at improving mortality in childhood. The objective of this study was to determine if mortality rates have changed over the past few decades. Children born with achondroplasia during 1996 to 2003 were ascertained from the Texas Birth Defects Registry and matched with death certificate data from the Bureau of Vital Statistics through 2007. Infant and overall mortality rates, both crude and standardized to the 2005 (SMR2005 ) and 1975 (SMR1975 ) U.S. populations, were calculated. 106 children born with achondroplasia were identified. Four deaths were reported, with all occurring in the first year of life (mortality rate: 41.4 /1000 live-births). Infant mortality was higher when standardized to the 2005 U.S. population (SMR2005 :6.02, 95% CI:1.64-15.42) than the 1975 population (SMR1975 :2.58, 95% CI:0.70-6.61). The higher SMR2005 compared with SMR1975 , along with the fact that SMR1975 was nearly half that of a previous cohort reported 25 years ago (rate ratio: 0.53, 95% CI: 0.11-2.25), reflect a discrepancy in the changes in mortality in the overall population and in our cohort. Although an overall improvement in mortality, especially after the first year of life, is observed in our cohort, children with achondroplasia are still at a much higher risk of death compared with the general population. A longer follow-up is needed to elucidate whether evaluation/intervention changes have resulted in significant improvement in long-term survival among these patients.

  12. Iraq War mortality estimates: A systematic review

    Directory of Open Access Journals (Sweden)

    Guyatt Gordon H


    Full Text Available Abstract Background In March 2003, the United States invaded Iraq. The subsequent number, rates, and causes of mortality in Iraq resulting from the war remain unclear, despite intense international attention. Understanding mortality estimates from modern warfare, where the majority of casualties are civilian, is of critical importance for public health and protection afforded under international humanitarian law. We aimed to review the studies, reports and counts on Iraqi deaths since the start of the war and assessed their methodological quality and results. Methods We performed a systematic search of 15 electronic databases from inception to January 2008. In addition, we conducted a non-structured search of 3 other databases, reviewed study reference lists and contacted subject matter experts. We included studies that provided estimates of Iraqi deaths based on primary research over a reported period of time since the invasion. We excluded studies that summarized mortality estimates and combined non-fatal injuries and also studies of specific sub-populations, e.g. under-5 mortality. We calculated crude and cause-specific mortality rates attributable to violence and average deaths per day for each study, where not already provided. Results Thirteen studies met the eligibility criteria. The studies used a wide range of methodologies, varying from sentinel-data collection to population-based surveys. Studies assessed as the highest quality, those using population-based methods, yielded the highest estimates. Average deaths per day ranged from 48 to 759. The cause-specific mortality rates attributable to violence ranged from 0.64 to 10.25 per 1,000 per year. Conclusion Our review indicates that, despite varying estimates, the mortality burden of the war and its sequelae on Iraq is large. The use of established epidemiological methods is rare. This review illustrates the pressing need to promote sound epidemiologic approaches to determining

  13. Sunnier European countries have lower melanoma mortality. (United States)

    Shipman, A R; Clark, A B; Levell, N J


    Doubt has been cast on sunlight as the major causative factor for malignant melanoma. We performed statistical analysis of the average annual sunlight hours in 36 European capital cities compared with the country's melanoma mortality rate. A significant inverse proportionality was identified in both men and women, indicating that sun exposure is unlikely to be the strongest factor affecting mortality from malignant melanoma. © The Author(s).

  14. Flavonoid intake and all-cause mortality. (United States)

    Ivey, Kerry L; Hodgson, Jonathan M; Croft, Kevin D; Lewis, Joshua R; Prince, Richard L


    Flavonoids are bioactive compounds found in foods such as tea, chocolate, red wine, fruit, and vegetables. Higher intakes of specific flavonoids and flavonoid-rich foods have been linked to reduced mortality from specific vascular diseases and cancers. However, the importance of flavonoids in preventing all-cause mortality remains uncertain. The objective was to explore the association between flavonoid intake and risk of 5-y mortality from all causes by using 2 comprehensive food composition databases to assess flavonoid intake. The study population included 1063 randomly selected women aged >75 y. All-cause, cancer, and cardiovascular mortalities were assessed over 5 y of follow-up through the Western Australia Data Linkage System. Two estimates of flavonoid intake (total flavonoidUSDA and total flavonoidPE) were determined by using food composition data from the USDA and the Phenol-Explorer (PE) databases, respectively. During the 5-y follow-up period, 129 (12%) deaths were documented. Participants with high total flavonoid intake were at lower risk [multivariate-adjusted HR (95% CI)] of 5-y all-cause mortality than those with low total flavonoid consumption [total flavonoidUSDA: 0.37 (0.22, 0.58); total flavonoidPE: 0.36 (0.22, 0.60)]. Similar beneficial relations were observed for both cardiovascular disease mortality [total flavonoidUSDA: 0.34 (0.17, 0.69); flavonoidPE: 0.32 (0.16, 0.61)] and cancer mortality [total flavonoidUSDA: 0.25 (0.10, 0.62); flavonoidPE: 0.26 (0.11, 0.62)]. Using the most comprehensive flavonoid databases, we provide evidence that high consumption of flavonoids is associated with reduced risk of mortality in older women. The benefits of flavonoids may extend to the etiology of cancer and cardiovascular disease. © 2015 American Society for Nutrition.

  15. Hypothyroidism and Mortality among Dialysis Patients (United States)

    Rhee, Connie M.; Alexander, Erik K.; Bhan, Ishir


    Summary Background and objectives Hypothyroidism is highly prevalent among ESRD patients, but its clinical significance and the benefits of thyroid hormone replacement in this context remain unclear. Design, setting, participants, & measurements This study examined the association between hypothyroidism and all-cause mortality among 2715 adult dialysis patients with baseline thyrotropin levels measured between April of 2005 and April of 2011. Mortality was ascertained from Social Security Death Master Index and local registration systems. The association between hypothyroidism (thyrotropin greater than assay upper limit normal) and mortality was estimated using Cox proportional hazards models. To reduce the risk of observing reverse-causal associations, models included a 30-day lag between thyrotropin measurement and at-risk time. Results Among 350 (12.9%) hypothyroid and 2365 (87.1%) euthyroid (assay within referent range) patients, 917 deaths were observed during 5352 patient-years of at-risk time. Hypothyroidism was associated with higher mortality. Compared with thyrotropin in the low-normal range (0.4–2.9 mIU/L), subclinical hypothyroidism (thyrotropin >upper limit normal and ≤10.0 mIU/L) was associated with higher mortality; high-normal thyrotropin (≥3.0 mIU/L and ≤upper limit normal) and overt hypothyroidism (thyrotropin >10.0 mIU/L) were associated with numerically greater risk, but estimates were not statistically significant. Compared with spontaneously euthyroid controls, patients who were euthyroid while on exogenous thyroid replacement were not at higher mortality risk, whereas patients who were hypothyroid were at higher mortality risk. Sensitivity analyses indicated that effects on cardiovascular risk factors may mediate the observed association between hypothyroidism and death. Conclusions These data suggest that hypothyroidism is associated with higher mortality in dialysis patients, which may be ameliorated by thyroid hormone replacement

  16. Air pollution and mortality: A history (United States)

    Anderson, H. R.

    Mortality is the most important health effect of ambient air pollution and has been studied the longest. The earliest evidence relates to fog episodes but with the development of more precise methods of investigation it is still possible to discern short-term temporal associations with daily mortality at the historically low levels of air pollution that now exist in most developed countries. Another early observation was that mortality was higher in more polluted areas. This has been confirmed by modern cohort studies that account for other potential explanations for such associations. There does not appear to be a threshold of effect within the ambient range of concentrations. Advances in the understanding of air pollution and mortality have been driven by the combined development of methods and biomedical concepts. The most influential methodological developments have been in time-series techniques and the establishment of large cohort studies, both of which are underpinned by advances in data processing and statistical analysis. On the biomedical side two important developments can be identified. One has been the application of the concept of multifactorial disease causation to explaining how air pollution may affect mortality at low levels and why thresholds are not obvious at the population level. The other has been an increasing understanding of how air pollution may plausibly have pathophysiological effects that are remote from the lung interface with ambient air. Together, these advances have had a profound influence on policies to protect public health. Throughout the history of air pollution epidemiology, mortality studies have been central and this will continue because of the widespread availability of mortality data on a large population scale and the weight that mortality carries in estimating impacts for policy development.

  19. Mortality in patients with pituitary disease.

    LENUS (Irish Health Repository)

    Sherlock, Mark


    Pituitary disease is associated with increased mortality predominantly due to vascular disease. Control of cortisol secretion and GH hypersecretion (and cardiovascular risk factor reduction) is key in the reduction of mortality in patients with Cushing\\'s disease and acromegaly, retrospectively. For patients with acromegaly, the role of IGF-I is less clear-cut. Confounding pituitary hormone deficiencies such as gonadotropins and particularly ACTH deficiency (with higher doses of hydrocortisone replacement) may have a detrimental effect on outcome in patients with pituitary disease. Pituitary radiotherapy is a further factor that has been associated with increased mortality (particularly cerebrovascular). Although standardized mortality ratios in pituitary disease are falling due to improved treatment, mortality for many conditions are still elevated above that of the general population, and therefore further measures are needed. Craniopharyngioma patients have a particularly increased risk of mortality as a result of the tumor itself and treatment to control tumor growth; this is a key area for future research in order to optimize the outcome for these patients.

  20. Studies of the mortality of A-bomb survivors: report 7. Mortality, 1950-1978: part II. Mortality from causes other than cancer and mortality in early entrants

    International Nuclear Information System (INIS)

    Kato, H.; Brown, C.C.; Hoel, D.G.; Shull, W.J.


    Deaths in the Radiation Effects Research Foundation (REFR) Life Span Study (LSS) sample have been determined for the 4 years 1975-1978, and mortality examined for the 28 years since 1950. An analysis of cancer mortality is presented separately. In this report, we examine whether mortality from causes other than cancer is also increased or whether a nonspecific acceleration of aging occurs. 1. Cumulative mortality from causes other than cancer, estimated by the life table method, does not increase with radiation dose in either city, in either sex, or in any of the five different age-at-the-time-of-bomb groups. 2. No specific cause of death, other than cancer, exhibits a significant relationship with A-bomb exposure. Thus there is still no evidence of a nonspecific acceleration of aging due to radiation in this cohort. 3. Mortality before the LSS sample was established has been reanalyzed using three supplementary mortality surveys to determine the magnitude of the possible bias from the exclusion of deaths prior to 1950. It is unlikely that such a bias seriously affects the interpretation of the radiation effects observed in the cohort after 1950. 4. No excess of deaths from leukemia or other malignant tumors is observed among early entrants into these cities in this cohort

  1. Characterizing mortality in pediatric tracheostomy patients. (United States)

    To assess the longitudinal risk of death following tracheostomy in the pediatric age group. Retrospective cohort study. Hospital records of 513 children (≤18 years) at a tertiary care children's hospital who underwent tracheostomy between 1984 and 2015 were reviewed. The primary outcome measure was time from tracheostomy to death. Secondary patient demographic and clinical characteristics were assessed, with likelihood of death using χ 2 tests and the Cox proportional hazards model. Median age at time of tracheostomy was 0.8 years (interquartile range, 0.3-5.2 years).The highest mortality rate (27.8%) was observed in patients in the 13- to 18-year-old age category; their mortality rate was significantly higher when compared to the lowest mortality risk group patients (age 1-4 years, P = .031). Timing of death was evenly distributed: 1 year after tracheostomy (35.3%). Patients who underwent tracheostomy for cardiopulmonary disease had an increased risk of mortality compared with airway obstruction (adjusted hazard ratio: 3.53, 95% confidence interval: 1.72-7.24, P tracheostomy have a high mortality rate, with an increased risk of death associated with a cardiopulmonary indication for undergoing tracheostomy. The majority of deaths occur after the index hospitalization during which the tracheostomy was performed. BPD and CHD are independent predictors of mortality in pediatric tracheostomy patients. 4 Laryngoscope, 127:1701-1706, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

  2. Income inequality and socioeconomic gradients in mortality. (United States)

    Wilkinson, Richard G; Pickett, Kate E


    We investigated whether the processes underlying the association between income inequality and population health are related to those responsible for the socioeconomic gradient in health and whether health disparities are smaller when income differences are narrower. We used multilevel models in a regression analysis of 10 age- and cause-specific US county mortality rates on county median household incomes and on state income inequality. We assessed whether mortality rates more closely related to county income were also more closely related to state income inequality. We also compared mortality gradients in more- and less-equal states. Mortality rates more strongly associated with county income were more strongly associated with state income inequality: across all mortality rates, r= -0.81; P=.004. The effect of state income inequality on the socioeconomic gradient in health varied by cause of death, but greater equality usually benefited both wealthier and poorer counties. Although mortality rates with steep socioeconomic gradients were more sensitive to income distribution than were rates with flatter gradients, narrower income differences benefit people in both wealthy and poor areas and may, paradoxically, do little to reduce health disparities.

  3. Macroeconomic fluctuations and mortality in postwar Japan. (United States)

    Granados, José A Tapia


    Recent research has shown that after long-term declining trends are excluded, mortality rates in industrial countries tend to rise in economic expansions and fall in economic recessions. In the present work, co-movements between economic fluctuations and mortality changes in postwar Japan are investigated by analyzing time series of mortality rates and eight economic indicators. To eliminate spurious associations attributable to trends, series are detrended either via Hodrick-Prescott filtering or through differencing. As previously found in other industrial economies, general mortality and age-specific death rates in Japan tend to increase in expansions and drop in recessions, for both males and females. The effect, which is slightly stronger for males, is particularly noticeable in those aged 45-64. Deaths attributed to heart disease, pneumonia, accidents, liver disease, and senility--making up about 41% of total mortality--tend to fluctuate procyclically, increasing in expansions. Suicides, as well as deaths attributable to diabetes and hypertensive disease, make up about 4% of total mortality and fluctuate countercyclically, increasing in recessions. Deaths attributed to other causes, making up about half of total deaths, don't show a clearly defined relationship with the fluctuations of the economy.

  4. Parental Incarceration and Child Mortality in Denmark (United States)

    Andersen, Signe Hald; Lee, Hedwig; Karlson, Kristian Bernt


    Objectives. We used Danish registry data to examine the association between parental incarceration and child mortality risk. Methods. We used a sample of all Danish children born in 1991 linked with parental information. We conducted discrete-time survival analysis separately for boys (n = 30 146) and girls (n = 28 702) to estimate the association of paternal and maternal incarceration with child mortality, controlling for parental sociodemographic characteristics. We followed the children until age 20 years or death, whichever came first. Results. Results indicated a positive association between paternal and maternal imprisonment and male child mortality. Paternal imprisonment was associated with lower child mortality risks for girls. The relationship between maternal imprisonment and female child mortality changed directions depending on the model, suggesting no clear association. Conclusions. These results indicate that the incarceration of a parent may influence child mortality but that it is important to consider the gender of both the child and the incarcerated parent. PMID:24432916

  5. Social integration and mortality in Australia. (United States)

    Siahpush, M; Singh, G K


    To investigate the relationship between social integration and mortality at the aggregate level of analysis. The data were compiled from several Australian Bureau of Statistics documents. The unit of analysis was State (Territory)-year. The multivariate regression analysis included data from all States and the Australian Capital Territory for 1990-96. Five indicators of social integration--percentage of people living alone; divorce rate; unemployment rate; proportion of people who are discouraged job seekers; and unionization rate--were used as predictors of nine measures of mortality. Higher levels of social integration, as measured by all indicators except unionization, were associated with lower mortality rates. In the case of unionization, higher levels were associated with increased mortality rates. Studies concerning the relationship between social integration and health should investigate the 'type' and 'level' of social integration that is conducive to better health. To help reduce disparities in health and mortality across communities, public health researchers and policy makers need to closely monitor geographic and temporal trends in social integration measures. Social policies that emphasise investment in social integration or social capital through job creation and training, provision of gainful employment and social services for discouraged and marginalized workers, improved work conditions and social support may lower mortality directly or through their beneficial effects on health-promoting behaviours such as reduced levels of smoking, drinking and physical inactivity.

  6. Update on worker mortality data at Hanford

    International Nuclear Information System (INIS)

    Gilbert, E.S.


    The subject of this paper is a study of the effects on mortality of occupational exposure to ionizing radiation at the Hanford plant. The Hanford plant, which is located in southeastern Washington State, was established in the early forties as an installation for plutonium production. Many workers employed by the various contractors hold jobs involving some exposure to radiation. Yearly records of this exposure, obtained from dosimeter readings, as well as occupational data, are maintained for all employees. Mortality data are obtained by having the Social Security Administration periodically search their records for deaths of persons identified in the personnel rosters of Hanford contractors. Published analyses of worker mortality at Hanford have included workers initially employed before 1965 and mortality up to April 1, 1974. In this paper, the mortality data are updated to include deaths up to May 1, 1977, workers employed 1965 and later, and the most recent exposure data. In addition to updating results of earlier analyses, this paper provides a discussion of the problems involved in analyzing and interpreting occupational exposure and mortality data. For a more detailed discussion of these problems the reader is referred to the papers noted above

  7. Infant mortality in the Marshall Islands. (United States)

    Levy, S J; Booth, H


    Levy and Booth present previously unpublished infant mortality rates for the Marshall Islands. They use an indirect method to estimate infant mortality from the 1973 and 1980 censuses, then apply indirect and direct methods of estimation to data from the Marshall Islands Women's Health Survey of 1985. Comparing the results with estimates of infant mortality obtained from vital registration data enables them to estimate the extent of underregistration of infant deaths. The authors conclude that 1973 census appears to be the most valid information source. Direct estimates from the Women's Health Survey data suggest that infant mortality has increased since 1970-1974, whereas the indirect estimates indicate a decreasing trend in infant mortality rates, converging with the direct estimates in more recent years. In view of increased efforts to improve maternal and child health in the mid-1970s, the decreasing trend is plausible. It is impossible to estimate accurately infant mortality in the Marshall Islands during 1980-1984 from the available data. Estimates based on registration data for 1975-1979 are at least 40% too low. The authors speculate that the estimate of 33 deaths per 1000 live births obtained from registration data for 1984 is 40-50% too low. In round figures, a value of 60 deaths per 1000 may be taken as the final estimate for 1980-1984.

  8. Recurring waterbird mortalities and unusual etiologies (United States)

    Cole, Rebecca A.; Franson, J. Christian; Boere, Gerard C.; Galbraith, Colin A.; Stroud, David A.


    Over the last decade, the National Wildlife Health Center of the United States Geological Survey has documented various largescale mortalities of birds caused by infectious and non-infectious disease agents. Some of these mortality events have unusual or unidentified etiologies and have been recurring. While some of the causes of mortalities have been elucidated, others remain in various stages of investigation and identification. Two examples are discussed: 1) Leyogonimus polyoon (Class: Trematoda), not found in the New World until 1999, causes severe enteritis and has killed over 15 000 American Coot Fulica americana in the upper mid-western United States. The geographic range of this parasite within North America is predicted to be limited to the Great Lakes Basin. 2) In the early 1990s, estimates of up to 6% of the North American population of the Eared Grebe Podiceps nigricollis died at Salton Sea, California, with smaller mortalities occurring throughout the 1990s. Birds were observed to have unusual preening behaviour, and to congregate at freshwater drains and move onto land. Suggested etiologies included interactions of contaminants, immuno-suppression, an unusual form of a bacterial disease, and an unknown biotoxin. During studies carried out from 2000 to 2003, Eared Grebe mortality did not approach the level seen in the early 1990s and, although bacteria were identified as minor factors, the principal cause of mortality remains undetermined. The potential population impact of these emerging and novel disease agents is currently unknown.

  9. Mortality rates among Arab Americans in Michigan. (United States)

    Dallo, Florence J; Schwartz, Kendra; Ruterbusch, Julie J; Booza, Jason; Williams, David R


    The objectives of this study were to: (1) calculate age-specific and age-adjusted cause-specific mortality rates for Arab Americans; and (2) compare these rates with those for blacks and whites. Mortality rates were estimated using Michigan death certificate data, an Arab surname and first name list, and 2000 U.S. Census data. Age-specific rates, age-adjusted all-cause and cause-specific rates were calculated. Arab Americans (75+) had higher mortality rates than whites and blacks. Among men, all-cause and cause-specific mortality rates for Arab Americans were in the range of whites and blacks. However, Arab American men had lower mortality rates from cancer and chronic lower respiratory disease compared to both whites and blacks. Among women, Arab Americans had lower mortality rates from heart disease, cancer, stroke, and diabetes than whites and blacks. Arab Americans are growing in number. Future study should focus on designing rigorous separate analyses for this population.

    Fabrizio Stracci


    Full Text Available OBJECTIVE: Avoidable mortality trends over the period 1994-2009 were calculated to evaluate health intervention by the health system of Umbria, a region of central Italy. MATERIALS AND METHODS: Mortality data were supplied by the regional causes of death registry. Rates were standardized to the 2001 census Italian population. Joinpoint regression was used to analyze the trends. RESULTS: Overall avoidable mortality rates decreased significantly both in males (-3.9% per year and in females (-3.6% per year. Mortality rates from ischemic heart and cerebrovascular disease about halved in the study period in both sexes. Avoidable mortality increased slightly only for a few causes (e.g. lung cancer in females. CONCLUSION: The overall trend of avoidable mortality indicates that the regional health/ preventive system is performing well.

    DEFF Research Database (Denmark)

    Zarulli, Virginia


    increase by age is missing. In the case of a shock, three scenarios may occur: mortality may be raised proportionally at all ages, more at older ages, or more at younger ages. Two cases of natural mortality experiments were analysed: Australian civilian prisoners in a Japanese camp during the Second World...... War and the Ukrainian Famine of 1933. The death rates of the prisoners of war were higher during imprisonment but the slope of the curve appeared to resemble that of the normal mortality regime. During the Ukrainian Famine, by contrast, the mortality curves in the different famine years were raised...

    young adult life into old age. One-year age-specific mortality rates between 30 and 79 years of age were computed for 14 different cancer sites among both males and females, in five ten-year birth cohorts and for the capital and provinces. The number of deaths at a particular age were found to follow...... a Poisson distribution and the mortality rate could be expressed by the function lx = bxk, where lx is the mortality rate at age x, and b and k are parameters to be estimated. With this model a straight line is obtained, when mortality and age are plotted on a double logarithmic scale. The maximum...

  15. National surgical mortality audit may be associated with reduced mortality after emergency admission. (United States)

    Kiermeier, Andreas; Babidge, Wendy J; McCulloch, Glenn A J; Maddern, Guy J; Watters, David A; Aitken, R James


    The Western Australian Audit of Surgical Mortality was established in 2002. A 10-year analysis suggested it was the primary driver in the subsequent fall in surgeon-related mortality. Between 2004 and 2010 the Royal Australasian College of Surgeons established mortality audits in other states. The aim of this study was to examine national data from the Australian Institute of Health and Welfare (AIHW) to determine if a similar fall in mortality was observed across Australia. The AIHW collects procedure and outcome data for all surgical admissions. AIHW data from 2005/2006 to 2012/2013 was used to assess changes in surgical mortality. Over the 8 years surgical admissions increased by 23%, while mortality fell by 18% and the mortality per admission fell by 33% (P audit was associated with a sharp decline in perioperative mortality. In the absence of any influences from other changes in clinical governance or new quality programmes it is probable it had a causal effect. The reduced mortality was most evident in high-risk patients. This study adds to the evidence that national audits are associated with improved outcomes. © 2017 Royal Australasian College of Surgeons.

  16. Association of BMI with risk of CVD mortality and all-cause mortality. (United States)

    To determine the relationship between BMI and risk of CVD mortality and all-cause mortality among Malaysian adults. Population-based, retrospective cohort study. Participants were followed up for 5 years from 2006 to 2010. Mortality data were obtained via record linkages with the Malaysian National Registration Department. Multiple Cox regression was applied to compare risk of CVD and all-cause mortality between BMI categories adjusting for age, gender and ethnicity. Models were generated for all participants, all participants the first 2 years of follow-up, healthy participants, healthy never smokers, never smokers, current smokers and former smokers. All fourteen states in Malaysia. Malaysian adults (n 32 839) aged 18 years or above from the third National Health and Morbidity Survey. Total follow-up time was 153 814 person-years with 1035 deaths from all causes and 225 deaths from CVD. Underweight (BMIBMI ≥30·0 kg/m2) was associated with a heightened risk of CVD mortality. Overweight (BMI=25·0-29·9 kg/m2) was inversely associated with risk of all-cause mortality. Underweight was significantly associated with all-cause mortality in all models except for current smokers. Overweight was inversely associated with all-cause mortality in all participants. Although a positive trend was observed between BMI and CVD mortality in all participants, a significant association was observed only for severe obesity (BMI≥35·0 kg/m2). Underweight was associated with increased risk of all-cause mortality and obesity with increased risk of CVD mortality. Therefore, maintaining a normal BMI through leading an active lifestyle and healthy dietary habits should continue to be promoted.

  17. Herd factors associated with dairy cow mortality. (United States)

    McConnel, C; Lombard, J; Wagner, B; Kopral, C; Garry, F


    Summary studies of dairy cow removal indicate increasing levels of mortality over the past several decades. This poses a serious problem for the US dairy industry. The objective of this project was to evaluate associations between facilities, herd management practices, disease occurrence and death rates on US dairy operations through an analysis of the National Animal Health Monitoring System's Dairy 2007 survey. The survey included farms in 17 states that represented 79.5% of US dairy operations and 82.5% of the US dairy cow population. During the first phase of the study operations were randomly selected from a sampling list maintained by the National Agricultural Statistics Service. Only farms that participated in phase I and had 30 or more dairy cows were eligible to participate in phase II. In total, 459 farms had complete data for all selected variables and were included in this analysis. Univariable associations between dairy cow mortality and 162 a priori identified operation-level management practices or characteristics were evaluated. Sixty of the 162 management factors explored in the univariate analysis met initial screening criteria and were further evaluated in a multivariable model exploring more complex relationships. The final weighted, negative binomial regression model included six variables. Based on the incidence rate ratio, this model predicted 32.0% less mortality for operations that vaccinated heifers for at least one of the following: bovine viral diarrhea, infectious bovine rhinotracheitis, parainfluenza 3, bovine respiratory syncytial virus, Haemophilus somnus, leptospirosis, Salmonella, Escherichia coli or clostridia. The final multivariable model also predicted a 27.0% increase in mortality for operations from which a bulk tank milk sample tested ELISA positive for bovine leukosis virus. Additionally, an 18.0% higher mortality was predicted for operations that used necropsies to determine the cause of death for some proportion of dead

    Full Text Available Records from 62-broiler farms located in Swat, North West Frontier Province (NWFP, Pakistan were, collected during the year 1998 to investigate prevalent diseases and overall mortality in broilers. Losses due Hydro-pericardium syndrome (HPS were the highest (17.05 ± 2.08% and the lowest due to coccidiosis 9.39 ± 3.82%. Non-significant differences existed in mortality caused by Newcastle, IBD and yolk sac infection. Differences in losses caused by infectious coryza, enteritis and coccidiosis were also non- significant. Average overall mortality was 13.05 ± 1.16%, representing 7.59 ± 0.46% losses from day-1 to day 14 and 18.52 ± 0.95% from day-15 till marketing of broilers (42-50 days. Lower (p<0.05 overall mortality was observed in broilers reared on well-finished concrete floors (12.43 ± 1.45 % than in those on brick+mud made floors (14.36 ± 1.55. Higher (p<0.05 overall mortality was found in overcrowded houses 5.60 ± 5.62% than in optimally utilized houses (10.69 ± 1.51%. Overall mortality was higher (p<0.05 in flocks under substandard vaccination schedule (15.92 ± 1.55% than in those maintained under standard lancination schedule (10.20 ± 1.21%. Overall mortality was higher (21.11 ± 3.39% when the interval between two batches was ≤ 7 days than 16-20 days (5.72 ± 3.01%. Lower (p<0.05 overall mortality was und in broilers maintained under good hygienic ( 11.59 ±1.93% and sanitary conditions ( 10.82 ± 1.16% compared to those under poor hygienic and sanitary conditions (14.12 ± 2.81% and 15.15 ± 1.68 %respectively. Maintenance of broilers under good hygienic conditions on well finished concrete floor, providing the required space/broiler, following recommended vaccination schedule without HPS vaccine and keeping 8.20 days interval between two batches were suggested as key factors in reducing mortality among broilers in Swat

    Arnetz, B.B; Raymond, L.W.; Nicolich, M.J.; Vargo, L.


    This is a study of a dynamic cohort of 13,250 commercial research and development personnel for whom information on occupational and education background and smoking was available. Their age-, sex-, race-, and period-adjusted death rates were compared with New Jersey rates and with an internal comparison population. The study groups had significantly fewer deaths from most major disease categories compared with other New Jersey residents. Among white male scientists and engineers, age-adjusted overall mortality and ischemic heart disease mortality were comparable to white male managers and support staff studied, whereas mortality from leukemia and lymphatic cancer was significantly elevated. Mechanics, however, had a significantly lower leukemia and lymphatic cancer mortality rate than did the comparison group. In a Poisson regression model in which white males and females from the study population were used, and for which the effects of age, smoking, college education category, period of hire, and years employed were controlled, scientists, engineers, and research technicians had elevated (nonsignificantly) mortality rates for leukemia and lymphatic cancer compared with managers and support staff. Smoking was an independent risk factor for leukemia and lymphatic cancer. Further work is needed to asses is specific environmental factors, such as benzene, other aromatics, radiation, medical treatment, and smoking habits, might have contributed to the above findings

  20. Lifestyle and mortality among Norwegian men. (United States)

    Rotevatn, S; Akslen, L A; Bjelke, E


    Information on six different habits (cigarette smoking, physical activity, frequency of alcohol and of fruit/vegetable consumption, and daily bread and potato consumption) was obtained by two postal surveys (1964 and 1967) among Norwegian men. The answers were related to mortality among 10,187 respondents ages 35-74 years at the start of the follow-up period (1967-1978). Analyses, stratified by age, place of residence, marital status, and socioeconomic group, showed an association between the six variables and observed/expected deaths, as well as odds ratio estimates. A health practice score, obtained by adding the number of favorable habits, showed a strong inverse relationship with total mortality as well as deaths from cancer, cardiovascular diseases, and other causes. Odds ratio estimates for men with only favorable habits vs those with at most one such habit, were 0.31 for total mortality, 0.44 for cancer, and 0.36 for cardiovascular mortality. Separate analyses among current smokers and nonsmokers showed a particularly strong association between the five other habits and mortality from cardiovascular disease.

  1. Alternative approach to analyzing occupational mortality data

    International Nuclear Information System (INIS)

    Gilbert, E.S.; Buchanan, J.A.


    It is widely recognized that analyzing occupational mortality by calculating standardized mortality ratios based on death rates from the general population is subject to a number of limitations. An alternative approach described in this report takes advantage of the fact that comparisons of mortality by subgroups and assessments of trends in mortality are often of equal or greater interest than overall assessments and that such comparisons do not require an external control. A computer program MOX (Mortality and Occupational Exposure) is available for performing the needed calculations for several diseases. MOX was written to asses the effect of radiation exposure on Hanford nuclear workers. For this application, analyses have been based on cumulative exposure computed (by MOX) from annual records of radiation exposure obtained from personal dosimeter readings. This program provides tests for differences and trends among subcategories defined by variables such as length of employment, job category, or exposure measurements and also provides control for age, calendar year, and several other potentially confounding variables. 29 references, 2 tables

  2. Perinatal mortality and socio-spatial inequalities

    Eunice Francisca Martins


    Full Text Available OBJECTIVE: to analyze the social inequalities in the distribution of perinatal mortality in Belo Horizonte. MATERIAL AND METHODS: the perinatal deaths of residents in Belo Horizonte in the period 2003 to 2007 were studied on the basis of the Information Systems on Mortality and Newborns. The space analysis and the Health Vulnerability Index were used to identify existing inequalities in the sanitary districts regarding coverage and risk, determined by the Odds Ratio and a value p<0.05. The multivariate analysis was used to describe a model for perinatal mortality. RESULTS: there was a proved variation in the numbers of perinatal mortality per one thousand total births in the sanitary districts (12.5 to 19.4, coverage areas (5.3 to 49.4 and areas of risk (13.2 to 20.7. The mortality rate diminished as the maternal schooling increased. The death rates deriving from asphyxia/hypoxia and non-specified fetal death grew with the increase of risk in the area. CONCLUSION: it was verified that the perinatal deaths are distributed in a differentiated form in relation to the space and the social vulnerabilities. The confrontation of this complex problem requires the establishment of intersecting partnerships.

  3. Spatial association between malaria pandemic and mortality

    B M Dansu


    Full Text Available Malaria pandemic (MP has been linked to a range of serious health problems including premature mortality. The main objective of this research is to quantify uncertainties about impacts of malaria on mortality. A multivariate spatial regression model was developed for estimation of the risk of mortality associated with malaria across Ogun State in Nigeria, West Africa. We characterize different local governments in the data and model the spatial structure of the mortality data in infants and pregnant women. A flexible Bayesian hierarchical model was considered for a space-time series of counts (mortality by constructing a likelihood-based version of a generalized Poisson regression model that combines methods for point-level misaligned data and change of support regression. A simple two-stage procedure for producing maps of predicted risk is described. Logistic regression modeling was used to determine an approximate risk on a larger scale, and geo-statistical ("Kriging" approaches were used to improve prediction at a local level. The results suggest improvement of risk prediction brought about in the second stage. The advantages and shortcomings of this approach highlight the need for further development of a better analytical methodology.

  4. Social inclusion affects elderly suicide mortality. (United States)

    Yur'yev, Andriy; Leppik, Lauri; Tooding, Liina-Mai; Sisask, Merike; Värnik, Peeter; Wu, Jing; Värnik, Airi


    National attitudes towards the elderly and their association with elderly suicide mortality in 26 European countries were assessed, and Eastern and Western European countries compared. For each country, mean age-adjusted, gender-specific elderly suicide rates in the last five years for which data had been available were obtained from the WHO European Mortality Database. Questions about citizens' attitudes towards the elderly were taken from the European Social Survey. Correlations between attitudes and suicide rates were analyzed using Pearson's test. Differences between mean scores for Western and Eastern European attitudes were calculated, and data on labor-market exit ages were obtained from the EUROSTAT database. Perception of the elderly as having higher status, recognition of their economic contribution and higher moral standards, and friendly feelings towards and admiration of them are inversely correlated with suicide mortality. Suicide rates are lower in countries where the elderly live with their families more often. Elderly suicide mortality and labor-market exit age are inversely correlated. In Eastern European countries, elderly people's status and economic contribution are seen as less important. Western Europeans regard the elderly with more admiration, consider them more friendly and more often have elderly relatives in the family. The data also show gender differences. Society's attitudes influence elderly suicide mortality; attitudes towards the elderly are more favorable among Western European citizens; and extended labor-market inclusion of the elderly is a suicide-protective factor.

  5. Evaluating Extensions to Coherent Mortality Forecasting Models

    Directory of Open Access Journals (Sweden)

    Syazreen Shair


    Full Text Available Coherent models were developed recently to forecast the mortality of two or more sub-populations simultaneously and to ensure long-term non-divergent mortality forecasts of sub-populations. This paper evaluates the forecast accuracy of two recently-published coherent mortality models, the Poisson common factor and the product-ratio functional models. These models are compared to each other and the corresponding independent models, as well as the original Lee–Carter model. All models are applied to age-gender-specific mortality data for Australia and Malaysia and age-gender-ethnicity-specific data for Malaysia. The out-of-sample forecast error of log death rates, male-to-female death rate ratios and life expectancy at birth from each model are compared and examined across groups. The results show that, in terms of overall accuracy, the forecasts of both coherent models are consistently more accurate than those of the independent models for Australia and for Malaysia, but the relative performance differs by forecast horizon. Although the product-ratio functional model outperforms the Poisson common factor model for Australia, the Poisson common factor is more accurate for Malaysia. For the ethnic groups application, ethnic-coherence gives better results than gender-coherence. The results provide evidence that coherent models are preferable to independent models for forecasting sub-populations’ mortality.

  6. Changing mortality and average cohort life expectancy

    Directory of Open Access Journals (Sweden)

    Robert Schoen


    Full Text Available Period life expectancy varies with changes in mortality, and should not be confused with the life expectancy of those alive during that period. Given past and likely future mortality changes, a recent debate has arisen on the usefulness of the period life expectancy as the leading measure of survivorship. An alternative aggregate measure of period mortality which has been seen as less sensitive to period changes, the cross-sectional average length of life (CAL has been proposed as an alternative, but has received only limited empirical or analytical examination. Here, we introduce a new measure, the average cohort life expectancy (ACLE, to provide a precise measure of the average length of life of cohorts alive at a given time. To compare the performance of ACLE with CAL and with period and cohort life expectancy, we first use population models with changing mortality. Then the four aggregate measures of mortality are calculated for England and Wales, Norway, and Switzerland for the years 1880 to 2000. CAL is found to be sensitive to past and present changes in death rates. ACLE requires the most data, but gives the best representation of the survivorship of cohorts present at a given time.

  7. Current therapies and mortality in acromegaly. (United States)

    Găloiu, S; Poiană, C


    Acromegaly is a rare disease most frequently due to a GH secreting pituitary adenoma. Without an appropriate therapy, life of patients with acromegaly can be shortened with ten years. Pituitary surgery is usually the first line therapy for GH secreting pituitary adenomas. A meta-analysis proved that mortality is much lower in operated patients, even uncured, than the entire group of patients and is similar with the general population in patients with GH30% utilization of SRAs reported a lower mortality ratio than studies with lower percentages of SRA administration. Although therapy with DA has long been used in patients with acromegaly, there are no studies reporting its effect on mortality, but its efficacy is limited by the low remission rate obtained. The use of conventional external radiotherapy, although with good remission rate in time, was linked with increased mortality, mostly due to cerebrovascular diseases. Mortality in acromegaly can be reduced to expected levels from general population by using modern therapies either in monotherapy or by using multimodal approaches in experienced centers.

  8. [In-hospital mortality due to stroke]. (United States)

    Rodríguez Lucci, Federico; Pujol Lereis, Virginia; Ameriso, Sebastián; Povedano, Guillermo; Díaz, María F; Hlavnicka, Alejandro; Wainsztein, Néstor A; Ameriso, Sebastián F


    Overall mortality due to stroke has decreased in the last three decades probable due to a better control of vascular risk factors. In-hospital mortality of stroke patients has been estimated to be between 6 and 14% in most of the series reported. However, data from recent clinical trials suggest that these figures may be substantially lower. Data from FLENI Stroke Data Bank and institutional mortality records between 2000 and 2010 were reviewed. Ischemic stroke subtypes were classified according to TOAST criteria and hemorrhagic stroke subtypes were classified as intraparenchymal hematoma, aneurismatic subarachnoid hemorrhage, arterio-venous malformation, and other intraparenchymal hematomas. A total of 1514 patients were studied. Of these, 1079 (71%) were ischemic strokes,39% large vessels, 27% cardioembolic, 9% lacunar, 14% unknown etiology, and 11% others etiologies. There were 435 (29%) hemorrhagic strokes, 27% intraparenchymal hematomas, 30% aneurismatic subarachnoid hemorrhage, 25% arterio-venous malformation, and 18% other intraparenchymal hematomas. Moreover, 38 in-hospital deaths were recorded (17 ischemic strokes and 21 hemorrhagic strokes), accounting for 2.5% overall mortality (1.7% in ischemic strokes and 4.8% in hemorrhagic strokes). No deaths occurred associated with the use of intravenous fibrinolytics occurred. In our Centre in-hospital mortality in patients with stroke was low. Management of these patients in a Centre dedicated to neurological diseases along with a multidisciplinary approach from medical and non-medical staff trained in the care of cerebrovascular diseases could, at least in part, account for these results.

  9. Mortality risk factor analysis in colonic perforation: would retroperitoneal contamination increase mortality in colonic perforation? (United States)

    Yoo, Ri Na; Kye, Bong-Hyeon; Kim, Gun; Kim, Hyung Jin; Cho, Hyeon-Min


    Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

  13. Maternal Mortality in Women with Epilepsy

    LENUS (Irish Health Repository)

    Holohan, M


    It is estimated that, in Ireland, there are 10,000 women with epilepsy of childbearing potential1. In this paper the maternal mortality rate for women with epilepsy attending the Rotunda Hospital Epilepsy Clinic 2004 - 2013 was determined. There were 3 maternal deaths in women with epilepsy during this time, which represents a mortality rate of 0.8%. In those women who died, there were concerns in relation to risks to the foetus by taking Anti-Epileptic Drugs (AED) and also issues with access to neurology services before pregnancy, acceptance of specialist support and lack of consistency in advice from health care professionals outside of Ireland. Implementing the nationally agreed care plan for women with epilepsy will improve the quality of care given and potentially we will see a reduction in maternal mortality in these women.

  14. Culturally divergent responses to mortality salience. (United States)

    Ma-Kellams, Christine; Blascovich, Jim


    Two experiments compared the effects of death thoughts, or mortality salience, on European and Asian Americans. Research on terror management theory has demonstrated that in Western cultural groups, individuals typically employ self-protective strategies in the face of death-related thoughts. Given fundamental East-West differences in self-construal (i.e., the independent vs. interdependent self), we predicted that members of Eastern cultural groups would affirm other people, rather than defend and affirm the self, after encountering conditions of mortality salience. We primed European Americans and Asian Americans with either a death or a control prime and examined the effect of this manipulation on attitudes about a person who violates cultural norms (Study 1) and on attributions about the plight of an innocent victim (Study 2). Mortality salience promoted culturally divergent responses, leading European Americans to defend the self and Asian Americans to defend other people.

  15. Education and Cause-specific Mortality

    Nordahl, Helene; Lange, Theis; Osler, Merete


    BACKGROUND: Differential exposures to behavioral risk factors have been shown to play an important mediating role on the education-mortality relation. However, little is known about the extent to which educational attainment interacts with health behavior, possibly through differential...... vulnerability. METHODS: In a cohort study of 76,294 participants 30 to 70 years of age, we estimated educational differences in cause-specific mortality from 1980 through 2009 and the mediating role of behavioral risk factors (smoking, alcohol intake, physical activity, and body mass index). With the use...... of marginal structural models and three-way effect decomposition, we simultaneously regarded the behavioral risk factors as intermediates and clarified the role of their interaction with educational exposure. RESULTS: Rate differences in mortality comparing participants with low to high education were 1...

  16. Unemployment and mortality: evidence from the PSID. (United States)

    Halliday, Timothy J


    We use micro-data to investigate the relationship between unemployment and mortality in the United States using Logistic regression on a sample of over 16,000 individuals. We consider baselines from 1984 to 1993 and investigate mortality up to ten years from the baseline. We show that poor local labor market conditions are associated with higher mortality risk for working-aged men and, specifically, that a one percentage point increase in the unemployment rate increases their probability of dying within one year of baseline by 6%. There is little to no such relationship for people with weaker labor force attachments such as women or the elderly. Our results contribute to a growing body of work that suggests that poor economic conditions pose health risks and illustrate an important contrast with studies based on aggregate data.

  17. Cognitive impairment and mortality among nonagenarians

    DEFF Research Database (Denmark)

    Andersen, Kjeld; Nybo, Hanne; Gaist, David


    Cognitive impairment has been associated with increased mortality. Most studies, however, have only included small numbers, if at all, of the very old. In a large nationwide survey of all Danes born in 1905 and still alive in 1998, where the baseline examination was conducted, we examined...... the impact of cognitive impairment on mortality over a 2-year period. No cognitive impairment was defined as a score of 24-30 points on the Mini Mental State Examination, mild cognitive impairment was defined as a score of 18-23 points, and severe impairment was defined as a score of 0-17 points. Cox...... regression analysis was applied to adjust for a number of known and suspected factors known or suspected of being associated with cognition and mortality (e.g. sociodemographic factors, sex, smoking, alcohol consumption, depressive symptoms, and physical abilities), and yielded hazard ratios (95% confidence...

    Background Periodontitis and edentulism are prevalent in patients with cirrhosis, but their clinical significance is largely unknown. Objective The objective of this article is to determine the association of severe periodontitis and edentulism with mortality in patients with cirrhosis. Methods...... A total of 184 cirrhosis patients underwent an oral examination. All-cause and cirrhosis-related mortality was recorded. The associations of periodontitis and edentulism with mortality were explored by Kaplan–Meier survival plots and Cox proportional hazards regression adjusted for age, gender, cirrhosis...... etiology, Child–Pugh score, Model for End-Stage Liver Disease score, smoker status, present alcohol use, comorbidity, and nutritional risk score. Results The total follow-up time was 74,197 days (203.14 years). At entry, 44% of the patients had severe periodontitis and 18% were edentulous. Forty...

  19. The effect of college education on mortality. (United States)

    Buckles, Kasey; Hagemann, Andreas; Malamud, Ofer; Morrill, Melinda; Wozniak, Abigail


    We exploit exogenous variation in years of completed college induced by draft-avoidance behavior during the Vietnam War to examine the impact of college on adult mortality. Our estimates imply that increasing college attainment from the level of the state at the 25th percentile of the education distribution to that of the state at the 75th percentile would decrease cumulative mortality for cohorts in our sample by 8 to 10 percent relative to the mean. Most of the reduction in mortality is from deaths due to cancer and heart disease. We also explore potential mechanisms, including differential earnings and health insurance.

    Ikram, Umar Z; Malmusi, Davide; Juel, Knud


    BACKGROUND: To integrate immigrants into their societies, European countries have adopted different types of policies, which may influence health through both material and psychosocial determinants. Recent studies have suggested poorer health outcomes for immigrants living in countries with poorly...... confounders and data comparability issues (e.g., French cross-sectional data) may affect the findings, this study suggests that different macro-level policy contexts may influence immigrants' mortality. Comparable mortality registration systems across Europe along with detailed socio-demographic information...... with their peers in the Netherlands, Turkish-born immigrants had higher all-cause mortality in Denmark (MRR men 1.92; 95% CI 1.74-2.13 and women 2.11; 1.80-2.47) but lower in France (men 0.64; 0.59-0.69 and women 0.58; 0.51-0.67). A similar pattern emerged for Moroccan-born immigrants. The relative differences...

    This book visualizes mortality dynamics in the Lexis diagram. While the standard approach of plotting death rates is also covered, the focus in this book is on the depiction of rates of mortality improvement over age and time. This rather novel approach offers a more intuitive understanding...... of the underlying dynamics, enabling readers to better understand whether period- or cohort-effects were instrumental for the development of mortality in a particular country. Besides maps for single countries, the book includes maps on the dynamics of selected causes of death in the United States...... Software to produce these types of surface maps. Readers are encouraged to use the presented tools to visualize other demographic data or any event that can be measured by age and calendar time, allowing them to adapt the methods to their respective research interests. The intended audience is anyone who...

    DEFF Research Database (Denmark)

    Wermuth, L; Stenager, E; Stenager, E


    INTRODUCTION: After the introduction of L-dopa the mortality rate in Parkinson's disease (PD) patients has changed, but is still higher than in the background population. MATERIAL & METHODS: Mortality, age at death and cause of death in a group of PD patients compared with the background population....... In the background population the median age at death was 80.69 years for men and 84.37 years for women. The SMR for men was 1.92 and for women 2.47. Infections, in particular lung infections, and heart diseases were the most common causes of death. Seventy percent of the death certificates had PD as a diagnosis....... CONCLUSION: It is likely that several factors can influence the changed mortality of PD: more effective treatment, changing diagnostic practice, and inter-disease competition....

  3. Leisure Time Physical Activity and Mortality

    DEFF Research Database (Denmark)

    Johnsen, Nina Føns; Ekblond, Annette; Thomsen, Birthe Lykke


    BACKGROUND: Some studies indicate that a large part of the beneficial effect of physical activity on mortality is confined to a threshold effect of participation. METHODS: Self-reported physical activity was investigated in relation to all-cause mortality in the Danish Diet, Cancer and Health...... cohort, including 29,129 women and 26,576 men aged 50-64 years at baseline 1993-1997. Using Cox proportional hazards models we investigated the associations between mortality rate and leisure time physical activity by exploring 1) participation (yes/no) in each type of activity; 2) a simple dose...... in specific leisure time physical activities, but not with more time spent on those activities. This could suggest that avoiding a sedative lifestyle is more important than a high volume of activity. Nonparticipation in these types of physical activity may be considered as risk factors....

  4. Nutrient enrichment increases mortality of mangroves.

    Directory of Open Access Journals (Sweden)

    Catherine E Lovelock

    Full Text Available Nutrient enrichment of the coastal zone places intense pressure on marine communities. Previous studies have shown that growth of intertidal mangrove forests is accelerated with enhanced nutrient availability. However, nutrient enrichment favours growth of shoots relative to roots, thus enhancing growth rates but increasing vulnerability to environmental stresses that adversely affect plant water relations. Two such stresses are high salinity and low humidity, both of which require greater investment in roots to meet the demands for water by the shoots. Here we present data from a global network of sites that documents enhanced mortality of mangroves with experimental nutrient enrichment at sites where high sediment salinity was coincident with low rainfall and low humidity. Thus the benefits of increased mangrove growth in response to coastal eutrophication is offset by the costs of decreased resilience due to mortality during drought, with mortality increasing with soil water salinity along climatic gradients.

  5. Maternal education and child mortality in Zimbabwe. (United States)

    Grépin, Karen A; Bharadwaj, Prashant


    In 1980, Zimbabwe rapidly expanded access to secondary schools, providing a natural experiment to estimate the impact of increased maternal secondary education on child mortality. Exploiting age specific exposure to these reforms, we find that children born to mothers most likely to have benefited from the policies were about 21% less likely to die than children born to slightly older mothers. We also find that increased education leads to delayed age at marriage, sexual debut, and first birth and that increased education leads to better economic opportunities for women. We find little evidence supporting other channels through which increased education might affect child mortality. Expanding access to secondary schools may greatly accelerate declines in child mortality in the developing world today. Copyright © 2015 Elsevier B.V. All rights reserved.

  6. A Relational Database of WHO Mortality Data Prepared to Facilitate Global Mortality Research

    Directory of Open Access Journals (Sweden)

    Albert de Roos


    Full Text Available Detailed world mortality data such as collected by the World Health Organization gives a wealth of information about causes of death worldwide over a time span of 60 year. However, the raw mortality data in text format as provided by the WHO is not directly suitable for systematic research and data mining. In this Data Paper, a relational database is presented that is created from the raw WHO mortality data set and includes mortality rates, an ICD-code table and country reference data. This enriched database, as a corpus of global mortality data, can be readily imported in relational databases but can also function as the data source for other types of databases. The use of this database can therefore greatly facilitate global epidemiological research that may provide new clues to genetic or environmental factors in the origins of diseases.

  9. Income distribution and mortality in Sweden

    Directory of Open Access Journals (Sweden)

    Christina Lindholm


    Full Text Available

    Background: The hypothesis that a high income inequality on a societal level is associated with poor health outcomes has been both rejected and accepted in empirical studies. Whether the influence of economic circumstances on health operates at the individual level or societal level has important implications on policy and intervention alternatives. The objective of this study was to analyse the relationship between income inequality and mortality in Swedish municipalities and if the relationship varies depending on the mean income or on the time-lag between income inequality and mortality.

    Methods: The study was based on register data on mean income and income inequality (Gini coefficients from Statistics Sweden 1982 and 1998, aggregated on the municipality level. Data on age-standardised death rates per 100,000 persons were obtained for 1983, 1988, 1993, 1998 and 2002. The analysis on 1998 was a test of the robustness of the results.

    Results: The relationship between high income inequality in 1982 and mortality in 1983 was negative with a similar relationship in 1998. Using latency periods, the results show a decreasing trend of mortality in relation to higher Gini coefficients. A positive relationship between Gini and mean income implies that municipalities with larger income distribution also had a higher mean income and vice versa.

    Conclusions: High income inequality does not have a negative effect on mortality in Swedish municipalities. The municipalities with high income inequality have also high mean income as opposed to many other countries. The income level seems to be more substantial for mortality than the income inequality.

  10. Estimating spatial inequalities of urban child mortality

    Directory of Open Access Journals (Sweden)

    John R. Weeks


    Full Text Available BACKGROUND Recent studies indicate that the traditional rural-urban dichotomy pointing to cities as places of better health in the developing world can be complicated by poverty differentials. Knowledge of spatial patterns is essential to understanding the processes that link individual demographic outcomes to characteristics of a place. A significant limitation, however, is the lack of spatial data and methods that offer flexibility in data inputs. OBJECTIVE This paper tackles some of the issues in calculating intra-urban child mortality by combining multiple data sets in Accra, Ghana and applying a new method developed by Rajaratnam et al. (2010 that efficiently uses summary birth histories for creating local-level measures of under-five child mortality (5q0. Intra-urban 5q0 rates are then compared with characteristics of the environment that may be linked to child mortality. METHODS Rates of child mortality are calculated for 16 urban zones within Accra for birth cohorts from 1987 to 2006. Estimates are compared to calculated 5q0 rates from full birth histories. 5q0 estimates are then related to zone measures of slum characteristics, housing quality, health facilities, and vegetation using a simple trendline R2 analysis. RESULTS Results suggest the potential value of the Rajaratnam et al. method at the micro-spatial scale. Estimated rates indicate that there is variability in child mortality between zones, with a spread of up to 50 deaths per 1,000 births. Furthermore, there is evidence that child mortality is connected to environmental factors such as housing quality, slum-like conditions, and neighborhood levels of vegetation.

  11. [Current tuberculosis mortality world-wide]. (United States)

    Haefliger, E; Rieder, H L


    The mortality rate still is an important index for assessment of tuberculosis. Statistical records are kept on the mortality rate on a worldwide basis--more than in the case of other tuberculosis parameters. They allow us to make valuable comparisons. They are also useful because the mortality is closely related to the morbidity. The present thesis is based on comparative figures from the 1989 volume of the WHO Health Statistics Annual. Various countries have been specially selected by the publisher--and subsequently also by us--for sake of clarity. The figures vary strongly within these countries, which was to be expected. The mortality rate varies in Europe (for each 100,000 residents) e.g. from 0.2 in the Netherlands to 8.15 in the Soviet Union. In the Americas the rates vary from 0.4 for Canada to 12.9 for Ecuador. In the Western Pacific region the mortality rates vary from 0.35 for Australia to 14.65 for China. On a worldwide basis, the share of deaths from tuberculosis among all causes of death varies from 0.02% in the Netherlands to 2.10% in the Republic of Korea. The relation of tuberculosis deaths with regard to sexes in Switzerland: 75.7% men, 24.3% women, which is more or less the European average. The lower the mortality rate for tuberculosis are, the lower the difference between the sexes appears to be. Similar facts are found with regard to the distribution of tuberculosis deaths according to age groups: the lower the tuberculosis rate, the more tuberculosis is found in older age groups. The tuberculosis deaths are percentage-wise similarly distributed to the respiratory organs and the other tuberculosis forms.(ABSTRACT TRUNCATED AT 250 WORDS)

  12. Adult mortality and children's transition into marriage

    Directory of Open Access Journals (Sweden)

    Sofya Krutikova


    Full Text Available Adult mortality due to HIV/AIDS and other diseases is posited to affect children through a number of pathways. On top of health and education outcomes, adult mortality can have significant effects on children by influencing demographic outcomes including the timing of marriage. This paper examines marriage outcomes for a sample of children interviewed in Tanzania in the early 1990s and re-interviewed in 2004. We find that while girls who became paternal orphans married at significantly younger ages, orphanhood had little effect on boys. On the other hand, non-parental deaths in the household affect the timing of marriage for boys.

  13. Mortality of fecal bacteria in seawater

    International Nuclear Information System (INIS)

    Garcia-Lara, J.; Menon, P.; Servais, P.; Billen, G.


    The authors propose a method for determining the mortality rate for allochthonous bacteria released in aquatic environments without interference due to the loss of culturability in specific culture media. This method consists of following the disappearance of radioactivity from the trichloracetic acid-insoluble fraction in water samples to which [ 3 H]thymidine-prelabeled allochthonous bacteria have been added. In coastal seawater, they found that the actual rate of disappearance of fecal bacteria was 1 order of magnitude lower than the rate of loss of culturability on specific media. Minor adaptation of the procedure may facilitate assessment of the effect of protozoan grazing and bacteriophage lysis on the overall bacterial mortality rate

    The Ontario Hydro mortality surveillance programme was the first such study established in any group of radiation workers. Copies of annual reports are available to senior officials of both management and union and to members of the general public. Apart from an elevated Standardized Mortality Ratio in the 15.0 - 19.9 cSv range, there is no suggestion of any rising cancer death rate with increased lifetime radiation dose. It should be noted that employees who had left before pensionable age were not included in the study. Results of the study are presented in tabular form

  15. An integrated national mortality surveillance system for death registration and mortality surveillance, China. (United States)

    Liu, Shiwei; Wu, Xiaoling; Lopez, Alan D; Wang, Lijun; Cai, Yue; Page, Andrew; Yin, Peng; Liu, Yunning; Li, Yichong; Liu, Jiangmei; You, Jinling; Zhou, Maigeng


    In China, sample-based mortality surveillance systems, such as the Chinese Center for Disease Control and Prevention's disease surveillance points system and the Ministry of Health's vital registration system, have been used for decades to provide nationally representative data on health status for health-care decision-making and performance evaluation. However, neither system provided representative mortality and cause-of-death data at the provincial level to inform regional health service needs and policy priorities. Moreover, the systems overlapped to a considerable extent, thereby entailing a duplication of effort. In 2013, the Chinese Government combined these two systems into an integrated national mortality surveillance system to provide a provincially representative picture of total and cause-specific mortality and to accelerate the development of a comprehensive vital registration and mortality surveillance system for the whole country. This new system increased the surveillance population from 6 to 24% of the Chinese population. The number of surveillance points, each of which covered a district or county, increased from 161 to 605. To ensure representativeness at the provincial level, the 605 surveillance points were selected to cover China's 31 provinces using an iterative method involving multistage stratification that took into account the sociodemographic characteristics of the population. This paper describes the development and operation of the new national mortality surveillance system, which is expected to yield representative provincial estimates of mortality in China for the first time.

  1. [Family planning can reduce maternal mortality]. (United States)

    Potts, M


    Although the maternal mortality rate receives no newspaper headlines, the number of mothers dying throughout the world is equivalent to a full jumbo jet crashing every 5 hours. Population surveys carried out between 1981-83 by Family Health International indicated maternal mortality rates of 1.9/1000 live births in Menoufia, Egypt, and 7.2/1000 in Bali, Indonesia. 20-25% of all deaths in women aged 15-49 were directly related to pregnancy and delivery, compared to 1% in western countries where there is better prenatal care, medical assistance in almost all deliveries, and elimination of most high risk pregnancies through voluntary fertility control. Maternal mortality could be controlled by teaching traditional midwives to identify high risk patients at the beginning of their pregnancies and to refer them to appropriate health services. Maternal survival would also be improved if all women were in good health at the beginning of pregnancy. Families should be taught to seek medical care for the mother in cases of prolonged labor; many women arrive at hospitals beyond hope of recovery after hours or days of futile labor. Health policy makers should set new priorities. Sri Lanka, for example, has a lower per capita income than Pakistan, but also a lower maternal mortality rate because of better use of family planning services, more emphasis on prenatal care, and a tradition of care and attention on the part of the public health services.

  4. Canadian Indian mortality during the 1980s. (United States)

    Trovato, F


    This study concerns itself with an investigation of general and cause-specific mortality differentials between Canadian Registered Indians (a subset of all aboriginals) and the larger Canadian population over two points in time, 1981 and 1991. Multivariate analyses are executed separately across four segments of the life cycle: adulthood, infancy, early childhood and late childhood. With respect to adults, Indians share relatively high rates of suicide, homicide and accidental causes of death; over time, their conditional risks of death due to cancer and circulatory afflictions have gone up significantly. Mortality disadvantages for the Indians are also pronounced in infancy, early childhood (ages 1-4) and late childhood (ages 5-14). Suicide, accidents, and violence constitute serious problems among 5-14 year olds, while infectious/parasitic, respiratory and circulatory complications, plus accidents and violence, are principle killers in infancy. For children aged 1-4, respiratory problems and accidents/violence are prime causes of premature death. This less-than-optimal mortality profile is reflective of persistent problems associated with prolonged socioeconomic marginalization. The temporal pattern of change in chronic/degenerative disease mortality among adult Indians suggests a movement of this population toward a mature stage of epidemiological transition.

  7. Factors Associated With Mortality of Thyroid Storm (United States)

    Ono, Yosuke; Ono, Sachiko; Yasunaga, Hideo; Matsui, Hiroki; Fushimi, Kiyohide; Tanaka, Yuji


    Abstract Thyroid storm is a life-threatening and emergent manifestation of thyrotoxicosis. However, predictive features associated with fatal outcomes in this crisis have not been clearly defined because of its rarity. The objective of this study was to investigate the associations of patient characteristics, treatments, and comorbidities with in-hospital mortality. We conducted a retrospective observational study of patients diagnosed with thyroid storm using a national inpatient database in Japan from April 1, 2011 to March 31, 2014. Of approximately 21 million inpatients in the database, we identified 1324 patients diagnosed with thyroid storm. The mean (standard deviation) age was 47 (18) years, and 943 (71.3%) patients were female. The overall in-hospital mortality was 10.1%. The number of patients was highest in the summer season. The most common comorbidity at admission was cardiovascular diseases (46.6%). Multivariable logistic regression analyses showed that higher mortality was significantly associated with older age (≥60 years), central nervous system dysfunction at admission, nonuse of antithyroid drugs and β-blockade, and requirement for mechanical ventilation and therapeutic plasma exchange combined with hemodialysis. The present study identified clinical features associated with mortality of thyroid storm using large-scale data. Physicians should pay special attention to older patients with thyrotoxicosis and coexisting central nervous system dysfunction. Future prospective studies are needed to clarify treatment options that could improve the survival outcomes of thyroid storm. PMID:26886648

    To estimate cardiovascular disease (CVD) mortality in relation to obesity and gender. Data from 11 prospective cohorts from four European countries including 23 629 men and 21 965 women, aged 24 to 99 years, with a median follow-up of 7.9 years were analyzed. Hazards ratios (HR) for CVD mortality in relation to baseline body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were estimated using Cox proportional hazards models with age as the timescale. Men had higher CVD mortality than women in all four BMI categories (obesity defined by WC, WHR or WHtR. The gender difference was slightly smaller in obese than in non-obese individuals; but the interaction was statistically significant only between gender and WC (p = 0.02), and WHtR (p = 0.01). None of the interaction terms was significant among non-diabetic individuals. Men had higher CVD mortality than women across categories of anthropometric measures of obesity. The gender difference was attenuated in obese individuals, which warrants further investigation.

  15. Political party affiliation, political ideology and mortality. (United States)

    Pabayo, Roman; Kawachi, Ichiro; Muennig, Peter


    Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. Data were derived from the 2008 General Social Survey-National Death Index data set. Cox proportional analysis models were used to determine whether political party affiliation or political ideology was associated with time to death. Also, we attempted to identify whether self-reported happiness and self-rated health acted as mediators between political beliefs and time to death. In this analysis of 32,830 participants and a total follow-up time of 498,845 person-years, we find that political party affiliation and political ideology are associated with mortality. However, with the exception of independents (adjusted HR (AHR)=0.93, 95% CI 0.90 to 0.97), political party differences are explained by the participants' underlying sociodemographic characteristics. With respect to ideology, conservatives (AHR=1.06, 95% CI 1.01 to 1.12) and moderates (AHR=1.06, 95% CI 1.01 to 1.11) are at greater risk for mortality during follow-up than liberals. Political party affiliation and political ideology appear to be different predictors of mortality. Published by the BMJ Publishing Group Limited.

    Full Text Available Abstract Background Neonatal mortality accounts for almost 40 per cent of under-five child mortality, globally. An understanding of the factors related to neonatal mortality is important to guide the development of focused and evidence-based health interventions to prevent neonatal deaths. This study aimed to identify the determinants of neonatal mortality in Indonesia, for a nationally representative sample of births from 1997 to 2002. Methods The data source for the analysis was the 2002–2003 Indonesia Demographic and Health Survey from which survival information of 15,952 singleton live-born infants born between 1997 and 2002 was examined. Multilevel logistic regression using a hierarchical approach was performed to analyze the factors associated with neonatal deaths, using community, socio-economic status and proximate determinants. Results At the community level, the odds of neonatal death was significantly higher for infants from East Java (OR = 5.01, p = 0.00, and for North, Central and Southeast Sulawesi and Gorontalo combined (OR = 3.17, p = 0.03 compared to the lowest neonatal mortality regions of Bali, South Sulawesi and Jambi provinces. A progressive reduction in the odds was found as the percentage of deliveries assisted by trained delivery attendants in the cluster increased. The odds of neonatal death were higher for infants born to both mother and father who were employed (OR = 1.84, p = 0.00 and for infants born to father who were unemployed (OR = 2.99, p = 0.02. The odds were also higher for higher rank infants with a short birth interval (OR = 2.82, p = 0.00, male infants (OR = 1.49, p = 0.01, smaller than average-sized infants (OR = 2.80, p = 0.00, and infant's whose mother had a history of delivery complications (OR = 1.81, p = 0.00. Infants receiving any postnatal care were significantly protected from neonatal death (OR = 0.63, p = 0.03. Conclusion Public health interventions directed at reducing neonatal death should

The data source for the analysis was the 2002-2003 Indonesia Demographic and Health Survey from which survival information of 15,952 singleton live-born infants born between 1997 and 2002 was examined. Multilevel logistic regression using a hierarchical approach was performed to analyze the factors associated with neonatal deaths, using community, socio-economic status and proximate determinants. At the community level, the odds of neonatal death was significantly higher for infants from East Java (OR = 5.01, p = 0.00), and for North, Central and Southeast Sulawesi and Gorontalo combined (OR = 3.17, p = 0.03) compared to the lowest neonatal mortality regions of Bali, South Sulawesi and Jambi provinces. A progressive reduction in the odds was found as the percentage of deliveries assisted by trained delivery attendants in the cluster increased. The odds of neonatal death were higher for infants born to both mother and father who were employed (OR = 1.84, p = 0.00) and for infants born to father who were unemployed (OR = 2.99, p = 0.02). The odds were also higher for higher rank infants with a short birth interval (OR = 2.82, p = 0.00), male infants (OR = 1.49, p = 0.01), smaller than average-sized infants (OR = 2.80, p = 0.00), and infant's whose mother had a history of delivery complications (OR = 1.81, p = 0.00). Infants receiving any postnatal care were significantly protected from neonatal death (OR = 0.63, p = 0.03). Public health interventions directed at reducing neonatal death should address community, household and individual level factors

    Mortality in Acute Respiratory Distress Syndrome (ARDS) is decreasing, although its prognosis after hospital discharge and the prognostic accuracy of Berlin's new ARDS stratification are uncertain. We did a restrospective analysis of hospital and 6 month mortality of patients with ARDS admitted to the Intensive Care Unit of a Univeristy Hospital in Buenos Aires, between January 2008 and June 2011. ARDS was defined by PaO2/FiO2 lower than 200 mmHg under ventilation with at least 10 cm H2O of PEEP and a FiO2 higher or equal than 0.5. and the presence of bilateral infiltrates in chest radiography, in the absence of cardiogenic acute pulmonary edema, during the first 72 hs of mechanical ventilation. Mortality associated risk factors, the use of rescue therapies and Berlin's stratification for moderate and severe ARDS patients were considered. Ninety eight patients were included; mean age was 59±19 years old, 42,9% had mayor co-morbidities; APACHE II at admission was 22±7; SOFA at day 1 was 8±3. Prone position ventilation was applied in 20,4% and rescue measures in 12,2% (12 patients with nitric oxide and 1 with extracorporeal membrane oxygenation). Hospital and 6 months mortality were 37.7 and 43.8% respectively. After logistic regression analysis, only age, the presence of septic shock at admission, Ppl >30 cmH2O, and major co-morbidities were independently associated with hospital outcome. There was no difference between moderate and severe groups (41,2 and 36,8% respectively; p=0,25). In this cohort, including patients with severe hypoxemia and high percentage of mayor co-morbidities, ARDS associated mortality was lower than some previous studies. There was no increase in mortality after hospital discharge. There was no difference in mortality between moderate and severe groups according to Berlin's definition.

    Nilgün Kültürsay


    Full Text Available Background: Perinatal, foetal and neonatal mortality statistics are important to show the development of a health care system in a country. However, in our country there are very few national and regional data about the changing pattern of perinatal neonatal mortality along with the development of new technologies in this area. Aims: Evaluation of the changes in mortality rates and the causes of perinatal and neonatal deaths within years in a perinatal reference centre which serves a high-risk population. Study Design: Cross-sectional retrospective study. Methods: The perinatal, neonatal and foetal mortality rates in the years 1979-1980 (1st time point and 1988-1989 (2nd time point were compared with the year 2008 (3rd time point. The causes of mortality were assessed by Wigglesworth classification and death reports. The neonatal mortality in the neonatal intensive care unit was also calculated. Results: Foetal mortality rates were 44/1000, 31.4/1000 and 41.75/1000 births, perinatal mortality rates were 35.6/1000, 18.8/1000 and 9/1000 births, and neonatal mortality rates were 35.6/1000, 18.8/1000 and 9/1000 live births for the three study time points, respectively. The mortality rate in neonatal intensive care unit decreased consistently from 33%, to 22.6% and 10%, respectively, together with decreasing neonatal mortality rates. The causes of perinatal deaths were foetal death 85%, immaturity 4%, and lethal congenital malformations 8% according to Wigglesworth classification in 2008, showing the high impact of foetal deaths on this high perinatal mortality rate. Infectious causes of neonatal deaths decreased but congenital anomalies increased in the last decades. Conclusion: Although neonatal mortality rate decreased significantly; foetal mortality rate has stayed unchanged since the late eighties. In order to decrease foetal and perinatal mortality rates more efficiently, reducing consanguineous marriages and providing better antenatal care for

  20. Remotely sensed predictors of conifer tree mortality during severe drought (United States)

    Brodrick, P. G.; Asner, G. P.


    Widespread, drought-induced forest mortality has been documented on every forested continent over the last two decades, yet early pre-mortality indicators of tree death remain poorly understood. Remotely sensed physiological-based measures offer a means for large-scale analysis to understand and predict drought-induced mortality. Here, we use laser-guided imaging spectroscopy from multiple years of aerial surveys to assess the impact of sustained canopy water loss on tree mortality. We analyze both gross canopy mortality in 2016 and the change in mortality between 2015 and 2016 in millions of sampled conifer forest locations throughout the Sierra Nevada mountains in California. On average, sustained water loss and gross mortality are strongly related, and year-to-year water loss within the drought indicates subsequent mortality. Both relationships are consistent after controlling for location and tree community composition, suggesting that these metrics may serve as indicators of mortality during a drought.

  1. Cancer mortality of Swiss men by occupation, 1979-1982. (United States)

    Minder, C E; Beer-Porizek, V


    Results of a study of male cancer mortality are presented by occupation. The data base consisted of the 1979-1982 mortality register and 1980 census data from Switzerland. In a novel approach, a linked subset of death certificates and census records was used to correct the numerator-denominator bias of standardized mortality ratios and their confidence intervals. Agricultural occupations exhibited low cancer mortality (exception: stomach cancer). Electricians suffered excess mortality from cancer of several sites. Foundry and chemical workers had elevated mortality risks for digestive tract cancers. Other metal workers suffered from high mortality from cancers of the respiratory organs. Construction workers were subject to high mortality from cancers of the upper digestive tract and lungs. Innkeepers, cooks, and owners or managers of guest houses had high rates of cancers of the digestive system. Occupations using combustion-powered equipment suffered from excess lung cancer mortality. In general the results of the study agree with those of several other studies.

    Damiani, P; Masse, H; Aubenque, M


    The departmental distributions of the probabilities of dying by age group and sex are analyzed for France in 1975. It is found that these distributions are the sum of two lognormal distributions. The authors deduce the existence of two populations that are distinguished by whether mortality was endogenous or exogenous. The relative importance of these two types of mortality is considered according to age. (summary in ENG)

  4. Ethnicity and infant mortality in Malaysia. (United States)

    Dixon, G


    Malaysian infant mortality differentials are a worthwhile subject for study, because socioeconomic development has very clearly had a differential impact by ethnic group. The Chinese rates of infant mortality are significantly lower than the Malay or Indian rates. Instead of examining the obvious access to care issues, this study considered factors related to the culture of infant care. Practices include the Chinese confinement of the mother in the first month after childbirth ("pe'i yue") and Pillsbury's 12 normative rules for Malaysian Chinese care. Malay practices vary widely by region and history. Indian mothers are restricted by diet. Data-recording flaws do not permit analysis of Sarawak or Sabah. The general assumption that Western medicine favors better health for mothers and infants is substantiated among peninsular communities, however, there are also negative impacts which affect infant mortality. The complex interaction of factors impacting on infant mortality reported in seven previous studies is discussed. A review of these studies reveals that immediate causes are infections, injuries, and dehydration. Indirect causes are birth weight or social and behavioral factors such as household income or maternal education. Indirect factors, which are amenable to planned change and influence the biological proximate determinants of infant mortality, are identified as birth weight, maternal age at birth, short pregnancy intervals or prior reproductive loss, sex of the child, birth order, duration of breast feeding and conditions of supplementation, types of household water and sanitation, year of child's birth, maternal education, household income and composition, institution of birth, ethnicity, and rural residence. Nine factors are identified empirically as not significant: maternal hours of work in the child's first year, maternal occupation, distance from home to workplace, presence of other children or servants, incidence of epidemics in the child's first

  5. Chronic pain and mortality: a systematic review.

    Full Text Available Chronic pain is common, often widespread and has a substantial impact on health and quality of life. The relationship between chronic pain and mortality is unclear. This systematic review aimed to identify and evaluate evidence for a relationship between chronic pain and mortality.A search of ten electronic databases including EMBASE and MEDLINE was conducted in March 2012, and updated until March 2014. Observational studies investigating the association between chronic or widespread pain (including fibromyalgia and mortality were included. Risk of bias was assessed and a meta-analysis was undertaken to quantify heterogeneity and pool results. A narrative review was undertaken to explore similarities and differences between the included studies.Ten studies were included in the review. Three reported significant associations between chronic or widespread pain and mortality in unadjusted results. In adjusted analyses, four studies reported a significant association. The remaining studies reported no statistically significant association. A meta-analysis showed statistically significant heterogeneity of results from studies using comparable outcome measures (n = 7(I2 = 78.8% and a modest but non-significant pooled estimate (MRR1.14,95%CI 0.95-1.37 for the relationship between chronic pain and all-cause mortality. This association was stronger when analysis was restricted to studies of widespread pain (n = 5,I2 = 82.3% MRR1.22(95%CI 0.93-1.60. The same pattern was observed with deaths from cancer and cardiovascular diseases. Heterogeneity is likely to be due to differences in study populations, follow-up time, pain phenotype, methods of analysis and use of confounding factors.This review showed a mildly increased risk of death in people with chronic pain, particularly from cancer. However, the small number of studies and methodological differences prevented clear conclusions from being drawn. Consistently applied definitions of

    Full Text Available EnglishMaternal mortality has been recognised as a public health problem in the developing countries. The situation concerning maternal mortality in Nepal remained unexplored and vague until the early 1990s. By using 1996 Nepal Family Health Survey, this study discusses the maternal mortality situation in Nepal and analyses the differentials in maternal mortality by place of residence,region, ethnic and religious groups, age at death, and parity. Almost 28 percent of deaths of women in reproductive age was accountable to maternal causes.Logistic regression analysis shows ‘ethnicity,’ ‘age of women,’ and ‘number of births’ as strong predictors of maternal mortality. A number of policy recommendations are suggested to help lower maternal mortality.FrenchLa mortalité liée à la maternité est un des phénomènes de santé qui a étéidentifié dans les pays en voie de développement.

  7. Drought impact on vegetation growth and mortality (United States)

    Xu, C.; Wang, M.; Allen, C. D.; McDowell, N. G.; Middleton, R. S.


    Vegetation is a key regulator of the global carbon cycle via CO2 absorption through photosynthesis and subsequent growth; however, low water availability, heat stress, and disturbances associated with droughts could substantially reduce vegetation growth and increase vegetation mortality. As far as we know, there are few studies have assessed the drought impact on vegetation growth and mortality at regional and global scales. In this study, we analyzed 13 Earth System models (ESMs) to quantify the impact of drought on GPP and linked the remote-sensing based tree mortality to observed drought indices to assess the drought impact on tree mortality in continental US (CONUS). Our analysis of 13 Earth System models (ESMs) shows that the average global gross primary production (GPP) reduction per year associated with extreme droughts over years 2075-2099 is predicted to be 3-5 times larger than that over years 1850-1999. The annual drought-associated reduction in GPP over years 2075-2099 could be 52 and 74 % of annual fossil fuel carbon emission during years 2000-2007. Increasing drought impacts on GPP are driven primarily by the increasing drought frequency. The risks of drought-associated GPP reduction are particularly high for temperate and tropical regions. The consistent prediction of higher drought-associated reduction in NPP across 13 ESMs suggests increasing impacts of drought on the global carbon cycle with atmospheric warming. Our analysis of drought impact on tree mortality showed that drought-associated carbon loss accounts for 12% of forest carbon loss in CONUS for 2000-2014, which is about one-fifth of that resulting from timber harvesting and 1.35 % of average annual fossil fuel emissions in the U.S. for the same period. The carbon stock loss from natural disturbances for 2000-2014 is approximately 75% of the total carbon loss from anthropogenic disturbance (timber harvesting), suggesting that natural disturbances play a very important role on forest

  8. Temperature extremes and infant mortality in Bangladesh: Hotter months, lower mortality. (United States)

    Babalola, Olufemi; Razzaque, Abdur; Bishai, David


    Our study aims to obtain estimates of the size effects of temperature extremes on infant mortality in Bangladesh using monthly time series data. Data on temperature, child and infant mortality were obtained for Matlab district of rural Bangladesh for January 1982 to December 2008 encompassing 49,426 infant deaths. To investigate the relationship between mortality and temperature, we adopted a regression with Autoregressive Integrated Moving Average (ARIMA) errors model of seasonally adjusted temperature and mortality data. The relationship between monthly mean and maximum temperature on infant mortality was tested at 0 and 1 month lags respectively. Furthermore, our analysis was stratified to determine if the results differed by gender (boys versus girls) and by age (neonates (≤ 30 days) versus post neonates (>30days and Bangladesh. Each degree Celsius increase in mean monthly temperature reduced monthly mortality by 3.672 (SE 1.544, pBangladesh. This may reflect a more heightened sensitivity of infants to hypothermia than hyperthermia in this environment.

  9. Exploring mortality among drug treatment clients: The relationship between treatment type and mortality. (United States)

    Lloyd, Belinda; Zahnow, Renee; Barratt, Monica J; Best, David; Lubman, Dan I; Ferris, Jason


    Studies consistently identify substance treatment populations as more likely to die prematurely compared with age-matched general population, with mortality risk higher out-of-treatment than in-treatment. While opioid-using pharmacotherapy cohorts have been studied extensively, less evidence exists regarding effects of other treatment types, and clients in treatment for other drugs. This paper examines mortality during and following treatment across treatment modalities. A retrospective seven-year cohort was utilised to examine mortality during and in the two years following treatment among clients from Victoria, Australia, recorded on the Alcohol and Drug Information Service database by linking with National Death Index. 18,686 clients over a 12-month period were included. Crude (CMRs) and standardised mortality rates (SMRs) were analysed in terms of treatment modality, and time in or out of treatment. Higher risk of premature death was associated with residential withdrawal as the last type of treatment engagement, while mortality following counselling was significantly lower than all other treatment types in the year post-treatment. Both CMRs and SMRs were significantly higher in-treatment than post-treatment. Better understanding of factors contributing to elevated mortality risk for clients engaged in, and following treatment, is needed to ensure that treatment systems provide optimal outcomes during and after treatment.

  10. The Rural Inpatient Mortality Study: Does Urban-Rural County Classification Predict Hospital Mortality in California? (United States)

    Linnen, Daniel T; Kornak, John; Stephens, Caroline


    Evidence suggests an association between rurality and decreased life expectancy. To determine whether rural hospitals have higher hospital mortality, given that very sick patients may be transferred to regional hospitals. In this ecologic study, we combined Medicare hospital mortality ratings (N = 1267) with US census data, critical access hospital classification, and National Center for Health Statistics urban-rural county classifications. Ratings included mortality for coronary artery bypass grafting, stroke, chronic obstructive pulmonary disease, heart attack, heart failure, and pneumonia across 277 California hospitals between July 2011 and June 2014. We used generalized estimating equations to evaluate the association of urban-rural county classifications on mortality ratings. Unfavorable Medicare hospital mortality rating "worse than the national rate" compared with "better" or "same." Compared with large central "metro" (metropolitan) counties, hospitals in medium-sized metro counties had 6.4 times the odds of rating "worse than the national rate" for hospital mortality (95% confidence interval = 2.8-14.8, p centers may contribute to these results, a potential factor that future research should examine.

    An epidemiological cohort study of some 300,000 Canadians enrolled in the National Dose Registry (NDR) is being undertaken to determine if there is excess cancer or other causes of mortality among those workers who are occupationally exposed to low levels of ionizing radiation. The results of this study may provide better understanding of the dose-response relationship for low doses of ionizing radiation and aid in the verification of risk estimates for radiation-induced cancer mortality. The Department of National Health and Welfare (DNHW) is responsible for the Registry; this study is being carried out by the Bureau of Radiation and Medical Devices (BRMD) with financial assistance and co-operation of various agencies including Statistics Canada and the Atomic Energy Control Board

  15. Invited commentary: Physical activity, mortality, and genetics. (United States)

    Rankinen, Tuomo; Bouchard, Claude


    The importance of regular physical activity to human health has been recognized for a long time, and a physically active lifestyle is now defined as a major component of public health policies. The independent contribution of regular physical activity to lower morbidity and mortality rates is generally accepted, and the biologic mechanisms mediating these health effects are actively investigated. A few years ago, data from the Finnish Twin Registry suggested that genetic selection may account for some of the physical-activity-related benefits on mortality rates. However, results from the Swedish Twin Registry study reported by Carlsson et al. in the current issue of the Journal (Am J Epidemiol 2007;166:255-259) do not support the genetic selection hypothesis. In this commentary, the authors review the nature of the associations among physical activity level, fitness, and longevity, with special reference to the role of human genetic variation, and discuss potential reasons for different outcomes of these large twin studies.

  16. [Perinatal mortality in foreign workers (author's transl)]. (United States)

    Höfling, H J; Jonas, R; Brusis, E; Lochmüller, H; Selbmann, H K; Holzmann, K; Zander, J


    From 1970 to 1972, there were 216 perinatal deaths among 5595 newborns at the I. Frauenklinik der Universität München. 54 of these deaths were children of foreign workers (so-called "Gastarbeiter"). The data have been processed on punch cards and analysed by a computer. The differences noted underwent significance testing by the CHI-Quadrat test. Only statistical significant results are published. The perinatal mortality in the above period shows no difference between foreign and German ward patients. There is, however, a significant lower perinatal mortality in private patients. We feel that this difference is due to a significant lower rate of prematures in the private patient group. The cocial status as well as higher interest and motivation in health resulting in better prenatal care are discussed as causal reasons for this fact.

    Definitions of underprivileged status based on race, gender and geographic location are neither sensitive nor specific; instead we proposed and validated a composite index of social adaptability (SAI). Index of social adaptability was calculated based on employment, education, income, marital status, and substance abuse, each factor contributing from 0 to 3 points. Index of social adaptability was validated in NHANES-3 by association with all-cause and cause-specific mortality. Weighted analysis of 19,593 subjects demonstrated mean SAI of 8.29 (95% CI 8.17-8.40). Index of social adaptability was higher in Whites, followed by Mexican-Americans and then the African-American population (ANOVA, p adaptability with a strong association with mortality, which can be used to identify underprivileged populations at risk of death.

  19. Effect of Boarding on Mortality in ICUs. (United States)

    Stretch, Robert; Della Penna, Nicolás; Celi, Leo Anthony; Landon, Bruce E


    Hospitals use a variety of strategies to maximize the availability of limited ICU beds. Boarding, which involves assigning patients to an open bed in a different subspecialty ICU, is one such practice employed when ICU occupancy levels are high, and beds in a particular unit are unavailable. Boarding disrupts the normal geographic colocation of patients and care teams, exposing patients to nursing staff with different training and expertise to those caring for nonboarders. We analyzed whether medical ICU patients boarding in alternative specialty ICUs are at increased risk of mortality. Retrospective cohort study using an instrumental variable analysis to control for unmeasured confounding. A semiparametric bivariate probit estimation strategy was employed for the instrumental model. Propensity score matching and standard logistic regression (generalized linear modeling) were used as robustness checks. The medical ICU of a tertiary care nonprofit hospital in the United States between 2002 and 2012. All medical ICU admissions during the specified time period. None. The study population consisted of 8,429 patients of whom 1,871 were boarders. The instrumental variable model demonstrated a relative risk of 1.18 (95% CI, 1.01-1.38) for ICU stay mortality for boarders. The relative risk of in-hospital mortality among boarders was 1.22 (95% CI, 1.00-1.49). GLM and propensity score matching without use of the instrument yielded similar estimates. Instrumental variable estimates are for marginal patients, whereas generalized linear modeling and propensity score matching yield population average effects. Mortality increased with boarding of critically ill patients. Further research is needed to identify safer practices for managing patients during periods of high ICU occupancy.

  20. Size-dependent mortality rate profiles. (United States)

    Roa-Ureta, Ruben H


    Knowledge of mortality rates is crucial to the understanding of population dynamics in populations of free-living fish and invertebrates in marine and freshwater environments, and consequently to sustainable resource management. There is a well developed theory of population dynamics based on age distributions that allow direct estimation of mortality rates. However, for most cases the aging of individuals is difficult or age distributions are not available for other reasons. The body size distribution is a widely available alternative although the theory underlying the formation of its shape is more complicated than in the case of age distributions. A solid theory of the time evolution of a population structured by any physiological variable has been developed in 1960s and 1970s by adapting the Hamilton-Jacobi formulation of classical mechanics, and equations to estimate the body size-distributed mortality profile have been derived for simple cases. Here I extend those results with regards to the size-distributed mortality profile to complex cases of non-stationary populations, individuals growing according to a generalised growth model and seasonally patterned recruitment pulses. I apply resulting methods to two cases in the marine environment, a benthic crustacean population that was growing during the period of observation and whose individuals grow with negative acceleration, and a sea urchin coastal population that is undergoing a stable cycle of two equilibrium points in population size whose individuals grow with varying acceleration that switches sign along the size range. The extension is very general and substantially widens the applicability of the theory. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Objectives: This paper aims to assess the relationship between the determinants of the psychosocial work environment, as expressed in terms of JDC or ERI models, and all-cause mortality in older individuals. Materials and Methods: The baseline study was conducted on a cohort comprising a random sample of 65-year-old community-dwelling citizens of Kraków, Poland. All of the 727 participants (410 women, 317 men were interviewed in their households in the period between 2001 and 2003; a structured questionnaire was used regarding their occupational activity history, which included indexes measuring particular dimensions of their psychosocial work environment based on Karasek's Job Demand-Control model and Siegrist's Effort-Reward Imbalance model, as well as health-related quality of life and demographic data. Mortality was ascertained by monitoring City Vital Records for 7 years. Analyses were conducted separately for men and women, with the multivariate Cox proportional hazard model. Results: During a 7-year follow-up period, 59 participants (8.1% died, including 21 women (5.1% of total women and 38 men (12% (p < 0.05. Significant differences in the number of deaths occurred regarding disproportion between physical demands and control in men: those with low physical demands and low control died three times more often than those with high control, regardless of the level of demands. The multivariate Cox proportional hazard model showed that significantly higher risk of death was observed only in men with low physical demands and low control, compared to those with low physical demands and high control (Exp(B = 4.65, 95% CI: 1.64-13.2. Conclusions: Observed differences in mortality patterns are similar to the patterns of relationships observed in health-related quality of life (HRQoL level at the beginning of old age; however, the relationship between efforts and rewards or demands and control and mortality was not fully confirmed.

  2. The epidemiology and mortality of pretibial lacerations. (United States)

    Cahill, K C; Gilleard, O; Weir, A; Cubison, T C S


    Pretibial lacerations are common injuries which have an underestimated mortality associated with their occurrence, and an under-appreciated morbidity associated with their treatment - they account for 5.2 out of every 1000 Emergency Department attendances in the United Kingdom, and occur mostly in the elderly. They are also increasingly being referred to plastic surgery units - the authors' department saw an increase from 58 referrals in twelve months in 2005/2006 to 113 referrals in six months in 2011. The Queen Victoria Hospital, East Grinstead, follows an evidence based and multi-disciplinary practice for the treatment of these injuries. The authors present the outcomes of patients referred to the hospital from the community and treated according to these guidelines, and compares the outcomes and mortality to a period prior to the introduction of this practise. The average time for skin grafted wounds to heal is found to be 59.8 days and for the donors it is 50.3 days, compared with an average time to healing of 123 days for those managed conservatively. The one month and one year mortality associated with these injuries is highlighted, as is the reduction in these figures following the adherence to the current treatment regime - prior to its introduction the 31 day mortality was 15%, and this was reduced to 4.3% by achievable changes in practice and treatment. Finally, the relevant extant research literature regarding pretibial lacerations is reviewed. Copyright © 2015 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

  3. Persistent insomnia is associated with mortality risk. (United States)

    Parthasarathy, Sairam; Vasquez, Monica M; Halonen, Marilyn; Bootzin, Richard; Quan, Stuart F; Martinez, Fernando D; Guerra, Stefano


    Insomnia has been associated with mortality risk, but whether this association is different in subjects with persistent vs intermittent insomnia is unclear. Additionally, the role of systemic inflammation in such an association is unknown. We used data from a community-based cohort to determine whether persistent or intermittent insomnia, defined based on persistence of symptoms over a 6-year period, was associated with death during the following 20 years of follow-up. We also determined whether changes in serum C-reactive protein (CRP) levels measured over 2 decades between study initiation and insomnia determination were different for the persistent, intermittent, and never insomnia groups. The results were adjusted for confounders such as age, sex, body mass index, smoking, physical activity, alcohol, and sedatives. Of the 1409 adult participants, 249 (18%) had intermittent and 128 (9%) had persistent insomnia. During a 20-year follow-up period, 318 participants died (118 due to cardiopulmonary disease). In adjusted Cox proportional-hazards models, participants with persistent insomnia (adjusted hazards ratio [HR] 1.58; 95% confidence interval [CI], 1.02-2.45) but not intermittent insomnia (HR 1.22; 95% CI, 0.86-1.74) were more likely to die than participants without insomnia. Serum CRP levels were higher and increased at a steeper rate in subjects with persistent insomnia as compared with intermittent (P = .04) or never (P = .004) insomnia. Although CRP levels were themselves associated with increased mortality (adjusted HR 1.36; 95% CI, 1.01-1.82; P = .04), adjustment for CRP levels did not notably change the association between persistent insomnia and mortality. In a population-based cohort, persistent, and not intermittent, insomnia was associated with increased risk for all-cause and cardiopulmonary mortality and was associated with a steeper increase in inflammation.

    Full Text Available Abstract Background Road traffic injuries (RTIs are among the leading causes of mortality in Vietnam. However, mortality data collection systems in Vietnam in general and for RTIs in particular, remain inconsistent and incomplete. Underlying distributions of external causes and body injuries are not available from routine data collection systems or from studies till date. This paper presents characteristics, user type pattern, seasonal distribution, and causes of 1,061 deaths attributable to road crashes ascertained from a national sample mortality surveillance system in Vietnam over a two-year period (2008 and 2009. Methods A sample mortality surveillance system was designed for Vietnam, comprising 192 communes in 16 provinces, accounting for approximately 3% of the Vietnamese population. Deaths were identified from commune level data sources, and followed up by verbal autopsy (VA based ascertainment of cause of death. Age-standardised mortality rates from RTIs were computed. VA questionnaires were analysed in depth to derive descriptive characteristics of RTI deaths in the sample. Results The age-standardized mortality rates from RTIs were 33.5 and 8.5 per 100,000 for males and females respectively. Majority of deaths were males (79%. Seventy three percent of all deaths were aged from 15 to 49 years and 58% were motorcycle users. As high as 80% of deaths occurred on the day of injury, 42% occurred prior to arrival at hospital, and a further 29% occurred on-site. Direct causes of death were identified for 446 deaths (42% with head injuries being the most common cause attributable to road traffic injuries overall (79% and to motorcycle crashes in particular (78%. Conclusion The VA method can provide a useful data source to analyse RTI mortality. The observed considerable mortality from head injuries among motorcycle users highlights the need to evaluate current practice and effectiveness of motorcycle helmet use in Vietnam.

    The objectives of this study are to evaluate the surgical management, both definitive and palliative, in selected patients with biliary obstruction and to find out the postoperative morbidity and mortality in these patients. Duration of the study is two years conducted from June 2002 to May 2004. The study was carried out at. the surgical. unit 4 of the Combined Military Hospital and surgical department of the Military Hospital. Thirty eight cases of biliary obstruction were included. A convenient sampling technique was followed. Data analyzed by using SPSS version 10.0 for windows on computer. Descriptive statistics like frequency, percentage, average etc were computed for data presentation. Any inferential test-was not found to be applicable for this descriptive type case series. We selected 38 patients with features of extrahepatic biliary obstruction. Out of these (n 38) 15 patients (39.5%) suffered from benign diseases while those having malignant diseases were 23 (60.5%). 19 (50%) patients died within two years of follow up while 19 (50%) were the survivors. Mortality was maximum for the malignant cases. In benign cases only one patient died. Maximum deaths 6 (31.6%) occurred in the period of up to one month of operation. 20 patients had one or another complication of operation and hence the morbidity came out to be 52%. According to our results the mortality and morbidity related to extrahepatic biliary obstruction in our patients was higher compared to other studies which can only be reduced by early detection and treatment.

  8. Minimization of heatwave morbidity and mortality. (United States)

    Kravchenko, Julia; Abernethy, Amy P; Fawzy, Maria; Lyerly, H Kim


    Global climate change is projected to increase the frequency and duration of periods of extremely high temperatures. Both the general populace and public health authorities often underestimate the impact of high temperatures on human health. To highlight the vulnerable populations and illustrate approaches to minimization of health impacts of extreme heat, the authors reviewed the studies of heat-related morbidity and mortality for high-risk populations in the U.S. and Europe from 1958 to 2012. Heat exposure not only can cause heat exhaustion and heat stroke but also can exacerbate a wide range of medical conditions. Vulnerable populations, such as older adults; children; outdoor laborers; some racial and ethnic subgroups (particularly those with low SES); people with chronic diseases; and those who are socially or geographically isolated, have increased morbidity and mortality during extreme heat. In addition to ambient temperature, heat-related health hazards are exacerbated by air pollution, high humidity, and lack of air-conditioning. Consequently, a comprehensive approach to minimize the health effects of extreme heat is required and must address educating the public of the risks and optimizing heatwave response plans, which include improving access to environmentally controlled public havens, adaptation of social services to address the challenges required during extreme heat, and consistent monitoring of morbidity and mortality during periods of extreme temperatures.

  9. Urban poverty and infant mortality rate disparities. (United States)

    Sims, Mario; Sims, Tammy L; Bruce, Marino A


    This study examined whether the relationship between high poverty and infant mortality rates (IMRs) varied across race- and ethnic-specific populations in large urban areas. Data were drawn from 1990 Census and 1992-1994 Vital Statistics for selected U.S. metropolitan areas. High-poverty areas were defined as neighborhoods in which > or = 40% of the families had incomes below the federal poverty threshold. Bivariate models showed that high poverty was a significant predictor of IMR for each group; however, multivariate analyses demonstrate that maternal health and regional factors explained most of the variance in the group-specific models of IMR. Additional analysis revealed that high poverty was significantly associated with minority-white IMR disparities, and country of origin is an important consideration for ethnic birth outcomes. Findings from this study provide a glimpse into the complexity associated with infant mortality in metropolitan areas because they suggest that the factors associated with infant mortality in urban areas vary by race and ethnicity.

  10. Cardiovascular Mortality Caused by Exposure to Radon

    International Nuclear Information System (INIS)

    Johnson, J. R.; Duport, P.


    Cardiovascular diseases (CVD) are reported as the cause of morbidity and mortality in humans exposed to (high) therapeutic doses of radiation, A-bomb explosions, accidental (Chernobyl liquidators) and occupational level of radiation while CVD risk does not appear to be elevated in other populations exposed to radiation CVD mortality also appears to be elevated, proportionally with radon progeny exposure in Newfoundland fluorspar miners. In addition, radiation exposure does not seem to increase and may indeed decrease CVD mortality or morbidity in mammals exposed to radiation in the laboratory. We have calculated the doses to blood and coronary artery wall from radon and progeny, and have concluded radon exposure may indeed increase the incidence of cardiovascular diseases and that a thorough investigation of that risk is justified, even at environmental and occupational levels. These contradictory observations suggest that radiation may be considered as one of many risk factors for cardiovascular diseases. As such, it may be necessary to reduce not only other risk factors as far as possible, but also to minimize exposures to radiation to further reduce the burden of cardiovascular diseases in the population.

  11. Job stress and mortality in older age. (United States)

    Tobiasz-Adamczyk, Beata; Brzyski, Piotr; Florek, Marzena; Brzyska, Monika


    This paper aims to assess the relationship between the determinants of the psychosocial work environment, as expressed in terms of JDC or ERI models, and all-cause mortality in older individuals. The baseline study was conducted on a cohort comprising a random sample of 65-year-old community-dwelling citizens of Kraków, Poland. All of the 727 participants (410 women, 317 men) were interviewed in their households in the period between 2001 and 2003; a structured questionnaire was used regarding their occupational activity history, which included indexes measuring particular dimensions of their psychosocial work environment based on Karasek's Job Demand-Control model and Siegrist's Effort-Reward Imbalance model, as well as health-related quality of life and demographic data. Mortality was ascertained by monitoring City Vital Records for 7 years. Analyses were conducted separately for men and women, with the multivariate Cox proportional hazard model. During a 7-year follow-up period, 59 participants (8.1%) died, including 21 women (5.1% of total women) and 38 men (12%) (p quality of life (HRQoL) level at the beginning of old age; however, the relationship between efforts and rewards or demands and control and mortality was not fully confirmed.

  12. Quantification of social contributions to earthquake mortality (United States)

    Main, I. G.; NicBhloscaidh, M.; McCloskey, J.; Pelling, M.; Naylor, M.


    Death tolls in earthquakes, which continue to grow rapidly, are the result of complex interactions between physical effects, such as strong shaking, and the resilience of exposed populations and supporting critical infrastructures and institutions. While it is clear that the social context in which the earthquake occurs has a strong effect on the outcome, the influence of this context can only be exposed if we first decouple, as much as we can, the physical causes of mortality from our consideration. (Our modelling assumes that building resilience to shaking is a social factor governed by national wealth, legislation and enforcement and governance leading to reduced levels of corruption.) Here we attempt to remove these causes by statistically modelling published mortality, shaking intensity and population exposure data; unexplained variance from this physical model illuminates the contribution of socio-economic factors to increasing earthquake mortality. We find that this variance partitions countries in terms of basic socio-economic measures and allows the definition of a national vulnerability index identifying both anomalously resilient and anomalously vulnerable countries. In many cases resilience is well correlated with GDP; people in the richest countries are unsurprisingly safe from even the worst shaking. However some low-GDP countries rival even the richest in resilience, showing that relatively low cost interventions can have a positive impact on earthquake resilience and that social learning between these countries might facilitate resilience building in the absence of expensive engineering interventions.

    Full Text Available OBJECTIVE: To evaluate the various causes of perinatal deaths and adopt strategies to improve perinatal outcome at a referral teaching hospital in North Kerala. METHODS: A prospective observational study conducted at Institute of Maternal and Child Health, Government Medical College, Kozhikode. All perinatal deaths during the period January 2013 to December 2014 were analysed and from this factors responsible for perinatal deaths were identified. RESULTS: Out of total 30,042 deliveries , there were 966 perinatal deaths during the study period. 566 were still births and 400 early neonatal deaths. The perinatal mortality rate was 31.1 per 1000 live births. Perinatal asphyxia was the major cause of perinatal mortality. The important factors contributing to perinatal asphyxia were prematurity (39%, abruptio placenta (19% and MSAF ( 12%. Among the antenatal factors, hypertensive disorders of pregnancy leading to iatrogenic elective preterm delivery were the most important. CONCLUSION: Perinatal asphyxia due to prematurity and low birth weight emerged as the most important cause of perinatal mortality in this study and hypertensive disorders of pregnancy were the most important antenatal complication leading to prematurity

    For 170 years, scientists have attempted to explain why consistent temporal patterns of death are observed among individuals within populations. Historical efforts to identify a {open_quotes}law of mortality{close_quotes} from these patterns ended in 1935 when it was declared that such a law did not exist. These empirical tests for a law of mortality were constructed using mortality curves based on all causes of death. We predicted that patterns of mortality consistent with the historical concept of a law would be revealed if mortality curves for species were constructed using only senescent causes of death. Using data on senescent mortality for laboratory animals and humans, we demonstrate that patterns of mortality overlap when compared on a biologically comparable time scale. These results are consistent with the existence of a law of mortality following sexual maturity as asserted by Benjamin Gompertz and Raymond Pearl. The societal, medical, and research implications of such a law are discussed.

    Srinivasan, M; Shetty, N; Gadekari, S; Thunga, G; Rao, K; Kunhikatta, V


    Severity or mortality prediction of nosocomial pneumonia could aid in the effective triage of patients and assisting physicians. To compare various severity assessment scoring systems for predicting intensive care unit (ICU) mortality in nosocomial pneumonia patients. A prospective cohort study was conducted in a tertiary care university-affiliated hospital in Manipal, India. One hundred patients with nosocomial pneumonia, admitted in the ICUs who developed pneumonia after >48h of admission, were included. The Nosocomial Pneumonia Mortality Prediction (NPMP) model, developed in our hospital, was compared with Acute Physiology and Chronic Health Evaluation II (APACHE II), Mortality Probability Model II (MPM 72  II), Simplified Acute Physiology Score II (SAPS II), Multiple Organ Dysfunction Score (MODS), Sequential Organ Failure Assessment (SOFA), Clinical Pulmonary Infection Score (CPIS), Ventilator-Associated Pneumonia Predisposition, Insult, Response, Organ dysfunction (VAP-PIRO). Data and clinical variables were collected on the day of pneumonia diagnosis. The outcome for the study was ICU mortality. The sensitivity and specificity of the various scoring systems was analysed by plotting receiver operating characteristic (ROC) curves and computing the area under the curve for each of the mortality predicting tools. NPMP, APACHE II, SAPS II, MPM 72  II, SOFA, and VAP-PIRO were found to have similar and acceptable discrimination power as assessed by the area under the ROC curve. The AUC values for the above scores ranged from 0.735 to 0.762. CPIS and MODS showed least discrimination. NPMP is a specific tool to predict mortality in nosocomial pneumonia and is comparable to other standard scores. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd.

  11. Low dose irradiation reduces cancer mortality rates

    International Nuclear Information System (INIS)

    Luckey, T.D.


    Low doses of ionizing radiation stimulate development, growth, memory, sensual acuity, fecundity, and immunity (Luckey, T.D., ''Radiation Hormesis'', CRC Press, 1991). Increased immune competence reduces cancer mortality rates and provides increased average lifespan in animals. Decreased cancer mortality rates in atom bomb victims who received low dose irradiation makes it desirable to examine populations exposed to low dose irradiation. Studies with over 300,000 workers and 7 million person-years provide a valid comparison of radiation exposed and control unclear workers (Luckey, T.D., Nurture with Ionizing Radiation, Nutrition and Cancer, 34:1-11, 1999). Careful selection of controls eliminated any ''healthy worker effect''. The person-year corrected average indicated the cancer mortality rate of exposed workers was only 51% that of control workers. Lung cancer mortality rates showed a highly significant negative correlation with radon concentrations in 272,000 U.S. homes (Cohen, B.L., Health Physics 68:157-174, 1995). In contrast, radon concentrations showed no effect on lung cancer rates in miners from different countries (Lubin, J.H. Am. J. Epidemiology 140:323-332, 1994). This provides evidence that excessive lung cancer in miners is caused by particulates (the major factor) or toxic gases. The relative risk for cancer mortality was 3.7% in 10,000 Taiwanese exposed to low level of radiation from 60 Co in their steel supported homes (Luan, Y.C. et al., Am. Nuclear Soc. Trans. Boston, 1999). This remarkable finding needs further study. A major mechanism for reduced cancer mortality rates is increased immune competence; this includes both cell and humoral components. Low dose irradiation increases circulating lymphocytes. Macrophage and ''natural killer'' cells can destroy altered (cancer) cells before the mass becomes too large. Low dose irradiation also kills suppressor T-cells; this allows helper T-cells to activate killer cells and antibody producing cells

  3. Decomposing changes in life expectancy: Compression versus shifting mortality

    Directory of Open Access Journals (Sweden)

    Marie-Pier Bergeron-Boucher


    Full Text Available Background: In most developed countries, mortality reductions in the first half of the 20th century were highly associated with changes in lifespan disparities. In the second half of the 20th century, changes in mortality are best described by a shift in the mortality schedule, with lifespan variability remaining nearly constant. These successive mortality dynamics are known as compression and shifting mortality, respectively. Objective: To understand the effect of compression and shifting dynamics on mortality changes, we quantify the gains in life expectancy due to changes in lifespan variability and changes in the mortality schedule, respectively. Methods: We introduce a decomposition method using newly developed parametric expressions of the force of mortality that include the modal age at death as one of their parameters. Our approach allows us to differentiate between the two underlying processes in mortality and their dynamics. Results: An application of our methodology to the mortality of Swedish females shows that, since the mid-1960s, shifts in the mortality schedule were responsible for more than 70Š of the increase in life expectancy. Conclusions: The decomposition method allows differentiation between both underlying mortality processes and their respective impact on life expectancy, and also determines when and how one process has replaced the other.

  8. Social Capital and Human Mortality: Explaining the Rural Paradox with County-Level Mortality Data (United States)

    Jensen, Leif; Haran, Murali


    The “rural paradox” refers to standardized mortality rates in rural areas that are unexpectedly low in view of well-known economic and infrastructural disadvantages there. We explore this paradox by incorporating social capital, a promising explanatory factor that has seldom been incorporated into residential mortality research. We do so while being attentive to spatial dependence, a statistical problem often ignored in mortality research. Analyzing data for counties in the contiguous United States, we find that: (1) the rural paradox is confirmed with both metro/non-metro and rural-urban continuum codes, (2) social capital significantly reduces the impacts of residence on mortality after controlling for race/ethnicity and socioeconomic covariates, (3) this attenuation is greater when a spatial perspective is imposed on the analysis, (4) social capital is negatively associated with mortality at the county level, and (5) spatial dependence is strongly in evidence. A spatial approach is necessary in county-level analyses such as ours to yield unbiased estimates and optimal model fit. PMID:25392565

  9. Heat Mortality Versus Cold Mortality: A Study of Conflicting Databases in the United States. (United States)

    Dixon, P. G.; Brommer, D. M.; Hedquist, B. C.; Kalkstein, A. J.; Goodrich, G. B.; Walter, J. C.; Dickerson, C. C., IV; Penny, S. J.; Cerveny, R. S.


    Studies, public reports, news reports, and Web sites cite a wide range of values associated with deaths resulting from excessive heat and excessive cold. For example, in the United States, the National Climatic Data Center's Storm Data statistics of temperature- related deaths are skewed heavily toward heat-related deaths, while the National Center for Health Statistics Compressed Mortality Database indicates the reverse—4 times more people die of “excessive cold” conditions in a given year than of “excessive heat.” In this study, we address the fundamental differences in the various temperature-related mortality databases, assess their benefits and limitations, and offer suggestions as to their use. These datasets suffer from potential incompleteness of source information, long compilation times, limited quality control, and the subjective determination of a direct versus indirect cause of death. In general, these separate mortality datasets should not be combined or compared, particularly with regard to policy determination. The use of gross mortality numbers appears to be one of the best means of determining temperature-related mortality, but those data must be detrended into order to remove a persistent winter-dominant death maximum and are difficult to obtain on a regional daily basis.

  10. Community variations in infant and child mortality in Peru. (United States)

    Edmonston, B; Andes, N


    Data from the national Peru Fertility Survey are used to estimate infant and childhood mortality ratios, 1968--77, for 124 Peruvian communities, ranging from small Indian hamlets in the Andes to larger cities on the Pacific coast. Significant mortality variations are found: mortality is inversely related to community population size and is higher in the mountains than in the jungle or coast. Multivariate analysis is then used to assess the influence of community population size, average female education, medical facilities, and altitude on community mortality. Finally, this study concludes that large-scale sample surveys, which include maternal birth history, add useful data for epidemiological studies of childhood mortality.

  12. Changes in the national mortality from leukaemia

    Energy Technology Data Exchange (ETDEWEB)

    Court Brown, W M; Doll, R


    In the last 30 years the number of deaths ascribed to leukaemia has increased steadily in all, countries for which adequate statistics are available. Death rates for England and Wales are given show that during this period the rate of mortality has increased threefold-a rate of increase which has been exceeded among the major causes of death only by cancer of the lung and coronary thrombosis. Clearly it is important to discover the reason for this change; more so, perhaps, because ionizing radiations are known to be capable of causing the disease and it is possible that some of the increase may have been due to their more extensive use.

  13. Mortality and air pollution: lessons from statistics

    International Nuclear Information System (INIS)

    Lipfert, F.W.


    Cross sectional studies which attempt to link persistent geographic differences in mortality rates with air pollution are reviewed. Some early studies are mentioned and detailed results are given for seven major contemporary studies, two of which are still in the publication process. Differences among the studies are discussed with regard to statistical techniques, trends in the results over time (1959 to 1974), and interpretation and use of the results. The analysis concludes that there are far too many problems with this technique to allow causality to be firmly established, and thus the results should not be used for cost benefit or policy analysis

  14. Estuary wader capacity following severe weather mortality

    International Nuclear Information System (INIS)

    Clark, J.A.; Baillie, S.R.; Clark, N.A.; Langston, R.H.W.


    The building of a tidal power barrage across an estuary may lead to substantial changes in its ecology. Many of Britain's estuaries hold internationally important numbers of waders. Careful consideration, therefore, needs to be given to the likely effects of tidal power barrages on wader populations. The opportunity for increased understanding of the mechanisms which govern wader populations was provided by a period of severe winter weather in 1991, which resulted in a substantial mortality of waders in eastern England. Such conditions are known to be stressful to birds and the study objectives were to investigate both the effects of and recovery from severe weather. (author)

  16. Respiratory disease mortality among uranium miners

    International Nuclear Information System (INIS)

    Archer, V.E.; Gillam, J.D.; Wagoner, J.K.


    A mortality analysis of a group of white and Indian uranium miners was done by a life-table method. A significant excess of respiratory cancer among both whites and Indians was found. Nonmalignant respiratory disease deaths among the whites are approaching cancer in importance as a cause of death, probably as a result of diffuse parenchymal radiation damage. Exposure-response curves for nonsmokers are linear for both respiratory cancer and ''other respiratory disease''. Cigaret smoking elevates and distorts that curve. Light cigaret smokers appear to be most vulnerable to lung parenchymal damage. The predominant histologic cancer among nonsmokers is small-cell undifferentiated, just as it is among cigaret smokers

  18. The BNFL radiation-mortality study

    International Nuclear Information System (INIS)

    Clough, E.A.; Schofield, G.B.


    An overview of an epidemiological study of BNFL employees and pensioners is presented. Overall, mortality patterns are similar to those in the general population. Non-cancer deaths among serving staff are significantly below those expected from national statistics due to the healthy worker effect; pensioners are more comparable to the national population. A similar pattern is found for lung malignancy. Observed deaths due to other cancers among serving staff and pensioners approximate closely to expectation; most are due to leukaemia but there is no evidence of any increased incidence at Sellafield where radiation exposures are higher than at other BNFL sites.

  19. Ionizing radiation decreases human cancer mortality rates

    International Nuclear Information System (INIS)

    Luckey, T.D.


    Information from nine studies with exposed nuclear workers and military observers of atmospheric bomb explosions confirms the results from animal studies which showed that low doses of ionizing radiation are beneficial. The usual ''healthy worker effect'' was eliminated by using carefully selected control populations. The results from 13 million person-years show the cancer mortality rate of exposed persons is only 65.6% that of carefully selected unexposed controls. This overwhelming evidence makes it politically untenable and morally wrong to withhold public health benefits of low dose irradiation. Safe supplementation of ionizing radiation should become a public health service. (author)

  2. Noncancer disease mortality among atomic bomb survivors

    International Nuclear Information System (INIS)

    Shimizu, Y.; Pierce, D.A.; Preston, D.L.; Mabuchi, K


    We examined the noncancer disease mortality for 86,572 atomic bomb survivors with dose estimates in the Radiation Effect Research Foundation's Life Span Study cohort between 1950 and 1990. There are 27,000 noncancer disease deaths and show a statistically significant increase in noncancer disease death rates with radiation dose. Increasing trends are observed for diseases of the circulatory, digestive, and respiratory systems. Rates for those exposed to 1 Sv are elevated about 10%, a relative increase that is considerably smaller than that for cancer. However, because noncancer deaths are much more common than cancer deaths, the absolute increase in noncancer rates is large. The estimates of the number of radiation-related noncancer deaths in the cohort to date are 50% to 100% of the number for solid cancer. There remains uncertainty about the shape of the dose-response. In particular, there is considerable uncertainty regarding risks in the range below 0.2 Sv of primary interest for radiation protection. The data are statistically consistent with curvilinear dose response functions that posit essentially zero risk for doses below 0.5 Sv, but there is no significant evidence against linearity. While the ERR for those exposed as children tends to increase with attained age, there is no statistically significant dependence of ERR on age at exposure or attained age. We also tried to estimate the lifetime risk, allowing for competing risks of cancer mortality. Especially we considered the impact of competing radiation risks since both cancer and noncancer mortality are in part radiation-related. These findings, as they are based on death certificates, have their limitation. However, the present findings can not be explained by biases due to misclassification of the cause of death and confounding factors. In the future, it will be necessary not only to continue mortality follow-up, but also to conduct a clinical study as well as animal experiments and biological

    Hirst, A.G.; Kiørboe, Thomas


    Using life history theory we make predictions of mortality rates in marine epi-pelagic copepods from field estimates of adult fecundity, development times and adult sex ratios. Predicted mortality increases with temperature in both broadcast and sac spawning copepods, and declines with body weight...... in broadcast spawners, while mortality in sac spawners is invariant with body size. Although the magnitude of copepod mortality does lie close to the overall general pattern for pelagic animals, copepod mortality scaling is much weaker, implying that small copepods are avoiding some mortality agent....../s that other pelagic animals of a similar size do not, We compile direct in situ estimates of copepod mortality and compare these with our indirect predictions; we find the predictions generally match the field measurements well with respect to average rates and patterns. Finally, by comparing in situ adult...

    Full Text Available We characterized the dynamics of mortality factors affecting immature developmental stages of the fall armyworm, Spodoptera frugiperda (J.E. Smith (Lepidoptera: Noctuidae. Multiple decrement life tables for egg and early larval stages of S. frugiperda in maize (Zea mays L. fields were developed with and without augmentative releases of Telenomus remus Nixon (Hymenoptera: Platygastridae from 2009 to 2011. Total egg mortality ranged from 73 to 81% and the greatest egg mortality was due to inviability, dislodgement, and predation. Parasitoids did not cause significant mortality in egg or early larval stages and the releases of T. remus did not increase egg mortality. Greater than 95% of early larvae died from predation, drowning, and dislodgment by rainfall. Total mortality due to these factors was largely irreplaceable. Results indicate that a greater effect in reducing generational survival may be achieved by adding mortality to the early larval stage of S. frugiperda.

  8. [Excess mortality associated with influenza in Spain in winter 2012]. (United States)

    León-Gómez, Inmaculada; Delgado-Sanz, Concepción; Jiménez-Jorge, Silvia; Flores, Víctor; Simón, Fernando; Gómez-Barroso, Diana; Larrauri, Amparo; de Mateo Ontañón, Salvador


    An excess of mortality was detected in Spain in February and March 2012 by the Spanish daily mortality surveillance system and the «European monitoring of excess mortality for public health action» program. The objective of this article was to determine whether this excess could be attributed to influenza in this period. Excess mortality from all causes from 2006 to 2012 were studied using time series in the Spanish daily mortality surveillance system, and Poisson regression in the European mortality surveillance system, as well as the FluMOMO model, which estimates the mortality attributable to influenza. Excess mortality due to influenza and pneumonia attributable to influenza were studied by a modification of the Serfling model. To detect the periods of excess, we compared observed and expected mortality. In February and March 2012, both the Spanish daily mortality surveillance system and the European mortality surveillance system detected a mortality excess of 8,110 and 10,872 deaths (mortality ratio (MR): 1.22 (95% CI:1.21-1.23) and 1.32 (95% CI: 1.29-1.31), respectively). In the 2011-12 season, the FluMOMO model identified the maximum percentage (97%) of deaths attributable to influenza in people older than 64 years with respect to the mortality total associated with influenza (13,822 deaths). The rate of excess mortality due to influenza and pneumonia and respiratory causes in people older than 64 years, obtained by the Serfling model, also reached a peak in the 2011-2012 season: 18.07 and 77.20, deaths per 100,000 inhabitants, respectively. A significant increase in mortality in elderly people in Spain was detected by the Spanish daily mortality surveillance system and by the European mortality surveillance system in the winter of 2012, coinciding with a late influenza season, with a predominance of the A(H3N2) virus, and a cold wave in Spain. This study suggests that influenza could have been one of the main factors contributing to the mortality excess

  11. Perinatal mortality in Indonesia: an unfinished agenda

    Directory of Open Access Journals (Sweden)

    Riawati Jahja


    Full Text Available Perinatal mortality is a profound issue in maternal and child health due to its close relation with the maternal condition. There exist Millennium Development Goals (MDGs which are to be achieved by 2015. These are coupled with a continuing need for comprehensively monitoring and identifying factors associated with perinatal mortality, which is a primary concern for developing countries inclusive of Indonesia. Previous and on-going health programs could have brought about strategic interventions but as different attributes can emerge due to epidemiological transition, and given the fact that associated factors may remain persistent, forward thinking strategies in public health are forever in need of renewal.     Results from our research show that educational variables, poor awareness towards proper antenatal care visits and weak services at the front-line of healthcare delivery (community outreach worsen the condition of childbearing women, raising the question of biological risk factors in line with socio-economic variables.

  13. National natality and fetal mortality surveys

    International Nuclear Information System (INIS)

    Roney, P.L.


    A project is described in which the Epidemiologic Studies Branch, DBE, is cooperating with the National Center for Health Statistics in a National Natality Survey and a National Fetal Mortality Survey of a sample of live births and of late fetal deaths (28 or more weeks gestation) in 1979. Questionnaires will be sent to a sample of mothers who had a live born infant or late fetal death in 1979, to hospitals in which the deliveries took place, to attending physicians, and all other possible sources of health care. The survey will provide quantitative information regarding use of ionizing and nonionizing radiation, including ultrasound, during pregnancy and possible associations between radiation and late fetal mortality. Specifically the study will provide information on the demographic and socioeconomic characteristics of the mothers and complications of pregnancy, labor, and delivery. The physical condition of the infant at birth is also included. This is one of many health surveys conducted routinely by the NCHS under the National Health Survey program

  14. Action plan to reduce perinatal mortality. (United States)

    Bhakoo, O N; Kumar, R


    The government of India has set a goal of reducing perinatal mortality from its current rate of 48/1000 to 30-35/1000 by the year 2000. Perinatal deaths result from maternal malnutrition, inadequate prenatal care, complications of delivery, and infections in the postpartum period. Since reductions in perinatal mortality require attention to social, economic, and behavioral factors, as well as improvements in the health care delivery system, a comprehensive strategy is required. Social measures, such as raising the age at marriage to 18 years for females, improving the nutritional status of adolescent girls, reducing the strenuousness of work during pregnancy, improving female literacy, raising women's status in the society and thus in the family, and poverty alleviation programs, would all help eliminate the extent of complications of pregnancy. Measures required to enhance infant survival include improved prenatal care, prenatal tetanus toxoid immunization, use of sterile disposable cord care kits, the provision of mucus extractors and resuscitation materials to birth attendants, the creation of neonatal care units in health facilities, and more efficient referral of high-risk newborns and mothers. Since 90% of births in rural India take place at home priority must be given to training traditional birth attendants in the identification of high risk factors during pregnancy, delivery, and the newborn period.

  15. Trends in Pulmonary Hypertension Mortality and Morbidity

    Alem Mehari


    Full Text Available Context. Few reports have been published regarding surveillance data for pulmonary hypertension, a debilitating and often fatal condition. Aims. We report trends in pulmonary hypertension. Settings and Design. United States of America; vital statistics, hospital data. Methods and Material. We used mortality data from the National Vital Statistics System (NVSS for 1999–2008 and hospital discharge data from the National Hospital Discharge Survey (NHDS for 1999–2009. Statistical Analysis Used. We present age-standardized rates. Results. Since 1999, the numbers of deaths and hospitalizations as well as death rates and hospitalization rates for pulmonary hypertension have increased. In 1999 death rates were higher for men than for women; however, by 2002, no differences by gender remained because of the increasing death rates among women and the declining death rates among men; after 2003 death rates for women were higher than for men. Death rates throughout the reporting period 1999–2008 were higher for blacks than for whites. Hospitalization rates in women were 1.3–1.6 times higher than in men. Conclusions. Pulmonary hypertension mortality and hospitalization numbers and rates increased from 1999 to 2008.

  19. Medieval monastic mortality: hazard analysis of mortality differences between monastic and nonmonastic cemeteries in England. (United States)

    DeWitte, Sharon N; Boulware, Jessica C; Redfern, Rebecca C


    Scholarship on life in medieval European monasteries has revealed a variety of factors that potentially affected mortality in these communities. Though there is some evidence based on age-at-death distributions from England that monastic males lived longer than members of the general public, what is missing from the literature is an explicit examination of how the risks of mortality within medieval monastic settings differed from those within contemporaneous lay populations. This study examines differences in the hazard of mortality for adult males between monastic cemeteries (n = 528) and non-monastic cemeteries (n = 368) from London, all of which date to between AD 1050 and 1540. Age-at-death data from all cemeteries are pooled to estimate the Gompertz hazard of mortality, and "monastic" (i.e., buried in a monastic cemetery) is modeled as a covariate affecting this baseline hazard. The estimated effect of the monastic covariate is negative, suggesting that individuals in the monastic communities faced reduced risks of dying compared to their peers in the lay communities. These results suggest better diets, the positive health benefits of religious behavior, better living conditions in general in monasteries, or selective recruitment of healthy or higher socioeconomic status individuals.

  20. [Liver cirrhosis mortality in Mexico. II. Excess mortality and pulque consumption]. (United States)

    Narro-Robles, J; Gutiérrez-Avila, J H; López-Cervantes, M; Borges, G; Rosovsky, H


    Over the years high cirrhosis mortality rates have been reported in Mexico City and in the surrounding states (Hidalgo, Tlaxcala, Puebla and the State of Mexico); on the contrary, well defined areas, such as the northern states, have shown a considerably lower mortality rate. This situation may indicate that some factors such as the pattern of alcoholic intake and other environmental characteristics could explain this striking difference. To determine the role of alcohol, the availability and consumption of alcohol at regional and state level were compared with cirrhosis mortality rates. A high and statistically significant correlation was found with pulque availability and consumption (r = 72-92%, p less than 0.01) in all periods of time under examination. On the contrary, a statistically significant negative association was observed with beer consumption and a positive, but not significant correlation, with distilled alcoholic beverages. Infectious hepatitis incidence, prevalence of exclusive use of native languages (as an indirect index of ethnic background) and nutritional deficiencies were also studied as possible risk factors. Nutritional deficiencies and the prevalence of exclusive use of náhuatl and otomí languages were positively correlated. These results can be useful to conduct further epidemiological studies still needed to determine the etiologic role of pulque consumption as well as of the other risk factors. Nonetheless, the current data stress the need to implement public health programs to reduce alcohol consumption, especially pulque, and to minimize the impact of these risk factors in high mortality areas.

  1. Hopelessly mortal: The role of mortality salience, immortality and trait self-esteem in personal hope. (United States)

    Wisman, Arnaud; Heflick, Nathan A


    Do people lose hope when thinking about death? Based on Terror Management Theory, we predicted that thoughts of death (i.e., mortality salience) would reduce personal hope for people low, but not high, in self-esteem, and that this reduction in hope would be ameliorated by promises of immortality. In Studies 1 and 2, mortality salience reduced personal hope for people low in self-esteem, but not for people high in self-esteem. In Study 3, mortality salience reduced hope for people low in self-esteem when they read an argument that there is no afterlife, but not when they read "evidence" supporting life after death. In Study 4, this effect was replicated with an essay affirming scientific medical advances that promise immortality. Together, these findings uniquely demonstrate that thoughts of mortality interact with trait self-esteem to cause changes in personal hope, and that literal immortality beliefs can aid psychological adjustment when thinking about death. Implications for understanding personal hope, trait self-esteem, afterlife beliefs and terror management are discussed.

    Full Text Available Abstract Background Complete and accurate ascertainment of mortality is critically important in any longitudinal study. Tracking of mortality is particularly essential among US military members because of unique occupational exposures (e.g., worldwide deployments as well as combat experiences. Our study objectives were to describe the early mortality experience of Panel 1 of the Millennium Cohort, consisting of participants in a 21-year prospective study of US military service members, and to assess data sources used to ascertain mortality. Methods A population-based random sample (n = 256,400 of all US military service members on service rosters as of October 1, 2000, was selected for study recruitment. Among this original sample, 214,388 had valid mailing addresses, were not in the pilot study, and comprised the group referred to in this study as the invited sample. Panel 1 participants were enrolled from 2001 to 2003, represented all armed service branches, and included active-duty, Reserve, and National Guard members. Crude death rates, as well as age- and sex-adjusted overall and age-adjusted, category-specific death rates were calculated and compared for participants (n = 77,047 and non-participants (n = 137,341 based on data from the Social Security Administration Death Master File, Department of Veterans Affairs (VA files, and the Department of Defense Medical Mortality Registry, 2001-2006. Numbers of deaths identified by these three data sources, as well as the National Death Index, were compared for 2001-2004. Results There were 341 deaths among the participants for a crude death rate of 80.7 per 100,000 person-years (95% confidence interval [CI]: 72.2,89.3 compared to 820 deaths and a crude death rate of 113.2 per 100,000 person-years (95% CI: 105.4, 120.9 for non-participants. Age-adjusted, category-specific death rates highlighted consistently higher rates among study non-participants. Although there were advantages and

    Full Text Available Background . Current mortality rates are essential for monitoring, understanding and developing policy for a population's health. Disease-specific Alaska Native mortality rates have been undergoing change. Objective . This article reports recent mortality data (2004–2008 for Alaska Native/American Indian (AN/AI people, comparing mortality rates to US white rates and examines changes in mortality patterns since 1980. Design . We used death record data from the state of Alaska, Department of Vital Statistics and SEER*Stat software from the National Cancer Institute to calculate age-adjusted mortality rates. Results . Annual age-adjusted mortality from all-causes for AN/AI persons during the period 2004–2008 was 33% higher than the rate for US whites (RR=1.33, 95% CI 1.29–1.38. Mortality rates were higher among AN/AI males than AN/AI females (1212/100,000 vs. 886/100,000. Cancer remained the leading cause of death among AN/AI people, as it has in recent previous periods, with an age-adjusted rate of 226/100,000, yielding a rate ratio (RR of 1.24 compared to US whites (95% CI 1.14–1.33. Statistically significant higher mortality compared to US white mortality rates was observed for nine of the ten leading causes of AN/AI mortality (cancer, unintentional injury, suicide, alcohol abuse, chronic obstructive pulmonary disease [COPD], cerebrovascular disease, chronic liver disease, pneumonia/influenza, homicide. Mortality rates were significantly lower among AN/AI people compared to US whites for heart disease (RR=0.82, the second leading cause of death. Among leading causes of death for AN/AI people, the greatest disparities in mortality rates with US whites were observed in unintentional injuries (RR=2.45 and suicide (RR=3.53. All-cause AN/AI mortality has declined 16% since 1980–1983, compared to a 21% decline over a similar period among US whites. Conclusion . Mortality rates and trends are essential to understanding the health of a

We examined age- and gender variations in all-cause mortality among youth aged 15-34 years across 52 countries. Methods: Using the 2014 WHO mortality database, mortality rates for all countries were computed for the latest available year between 2007 and 2012. Rates, rate ratios, and ordinary least squares (OLS and Poisson regression were used to analyze international variation in mortality. Results: Mortality rates among youth aged 15-34 years varied from a low of 28.4 deaths per 100,000 population for Hong Kong to a high of 250.6 for Russia and 619.1 for South Africa. For men aged 15-34, Singapore and Hong Kong had the lowest mortality rates (≈40 per 100,000, compared with South Africa and Russia with rates of 589.7 and 383.3, respectively. Global patterns in mortality among women were similar. Youth aged 15-24 in South Africa had 14 times higher mortality and those in the Philippines, Mexico, Russia, Colombia, and Brazil had 5-7 times higher mortality than those in Hong Kong.

  6. Predicting Early Mortality After Hip Fracture Surgery: The Hip Fracture Estimator of Mortality Amsterdam. (United States)

    Karres, Julian; Kieviet, Noera; Eerenberg, Jan-Peter; Vrouenraets, Bart C


    Early mortality after hip fracture surgery is high and preoperative risk assessment for the individual patient is challenging. A risk model could identify patients in need of more intensive perioperative care, provide insight in the prognosis, and allow for risk adjustment in audits. This study aimed to develop and validate a risk prediction model for 30-day mortality after hip fracture surgery: the Hip fracture Estimator of Mortality Amsterdam (HEMA). Data on 1050 consecutive patients undergoing hip fracture surgery between 2004 and 2010 were retrospectively collected and randomly split into a development cohort (746 patients) and validation cohort (304 patients). Logistic regression analysis was performed in the development cohort to determine risk factors for the HEMA. Discrimination and calibration were assessed in both cohorts using the area under the receiver operating characteristic curve (AUC), the Hosmer-Lemeshow goodness-of-fit test, and by stratification into low-, medium- and high-risk groups. Nine predictors for 30-day mortality were identified and used in the final model: age ≥85 years, in-hospital fracture, signs of malnutrition, myocardial infarction, congestive heart failure, current pneumonia, renal failure, malignancy, and serum urea >9 mmol/L. The HEMA showed good discrimination in the development cohort (AUC = 0.81) and the validation cohort (AUC = 0.79). The Hosmer-Lemeshow test indicated no lack of fit in either cohort (P > 0.05). The HEMA is based on preoperative variables and can be used to predict the risk of 30-day mortality after hip fracture surgery for the individual patient. Prognostic Level II.

  7. Mortality in Central Java: results from the indonesian mortality registration system strengthening project

    Directory of Open Access Journals (Sweden)

    Irianto Joko


    Full Text Available Abstract Background Mortality statistics from death registration systems are essential for health policy and development. Indonesia has recently mandated compulsory death registration across the entire country in December 2006. This article describes the methods and results from activities to ascertain causes of registered deaths in two pilot registration areas in Central Java during 2006-2007. The methods involved several steps, starting with adaptation of international standards for reporting causes of registered deaths for implementation in two sites, Surakarta (urban and Pekalongan (rural. Causes for hospital deaths were certified by attending physicians. Verbal autopsies were used for home deaths. Underlying causes were coded using ICD-10. Completeness of registration was assessed in a sample of villages and urban wards by triangulating data from the health sector, the civil registration system, and an independent household survey. Finally, summary mortality indicators and cause of death rankings were developed for each site. Findings A total of 10,038 deaths were registered in the two sites during 2006-2007; yielding annual crude death rates of 5.9 to 6.8 per 1000. Data completeness was higher in rural areas (72.5% as compared to urban areas (52%. Adjusted life expectancies at birth were higher for both males and females in the urban population as compared to the rural population. Stroke, ischaemic heart disease and chronic respiratory disease are prominent causes in both populations. Other important causes are diabetes and cancer in urban areas; and tuberculosis and diarrhoeal diseases in rural areas. Conclusions Non-communicable diseases cause a significant proportion of premature mortality in Central Java. Implementing cause of death reporting in conjunction with death registration appears feasible in Indonesia. Better collaboration between health and registration sectors is required to improve data quality. These are the first local

    International agencies have recently assigned Lebanon to the group H of countries with "no national data on maternal mortality," and estimated a corresponding maternal mortality ratio (MMR) of 150 per 100,000 live births. The Ministry of Public Health addressed the discrepancy perceived between the reality of the maternal mortality ratio experience in Lebanon and the international report by facilitating a hospital-based reproductive age mortality study, sponsored by the World Health Organization Representative Office in Lebanon, aiming at providing an accurate estimate of a maternal mortality ratio for 2008. The survey allowed a detailed analysis of maternal causes of deaths. Reproductive age deaths (15-49 years) were initially identified through hospital records. A trained MD traveled to each hospital to ascertain whether recorded deaths were in fact maternal deaths or not. ICD10 codes were provided by the medical controller for each confirmed maternal deaths. There were 384 RA death cases, of which 13 were confirmed maternal deaths (339%) (numerator). In 2008, there were 84823 live births in Lebanon (denominator). The MMR in Lebanon in 2008 was thus officially estimated at 23/100,000 live births, with an "uncertainty range" from 153 to 30.6. Hemorrhage was the leading cause of death, with double the frequency of all other causes (pregnancy-induced hypertension, eclampsia, infection, and embolism). This specific enquiry responded to a punctual need to correct a clearly inadequate report, and it should be relayed by an on-going valid surveillance system. Results indicate that special attention has to be devoted to the management of peri-partum hemorrhage cases. Arab, postpartum hemorrhage, development, pregnancy management, verbal autopsy

  9. Can the Obesity Surgery Mortality Risk Score predict postoperative complications other than mortality? (United States)

    Major, Piotr; Wysocki, Michał; Pędziwiatr, Michał; Małczak, Piotr; Pisarska, Magdalena; Migaczewski, Marcin; Winiarski, Marek; Budzyński, Andrzej


    Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are bariatric procedures with acceptable risk of postoperative morbidities and mortalities, but identification of high-risk patients is an ongoing issue. DeMaria et al. introduced the Obesity Surgery Mortality Risk Score (OS-MRS), which was designed for mortality risk assessment but not perioperative morbidity risk. To assess the possibility to use the OS-MRS to predict the risk of perioperative complications related to LSG and LRYGB. Retrospective analysis of patients operated on for morbid obesity was performed. Patients were evaluated before and after surgery. We included 408 patients (233 LSG, 175 LRYGB). Perioperative complications were defined as adverse effects in the 30-day period. The Clavien-Dindo scale was used for description of complications. Patients were assigned to five grades and three classes according to the OS-MRS results, then risk of morbidity was analyzed. Complications were observed in 30 (7.35%) patients. Similar morbidity was related to both procedures (OR = 1.14, 95% CI: 0.53-2.44, p = 0.744). The reoperation and mortality rates were 1.23% and 0.49% respectively. There were no significant differences in median OS-MRS value between the group without and the group with perioperative complications. There were no significant differences in OS-MRS between groups (p = 0.091). Obesity Surgery Mortality Risk Score was not related to Clavien-Dindo grades (p = 0.800). It appears that OS-MRS is not useful in predicting risk of perioperative morbidity after bariatric procedures.

  10. Winter Season Mortality: Will Climate Warming Bring Benefits? (United States)

    Kinney, Patrick L; Schwartz, Joel; Pascal, Mathilde; Petkova, Elisaveta; Tertre, Alain Le; Medina, Sylvia; Vautard, Robert


    Extreme heat events are associated with spikes in mortality, yet death rates are on average highest during the coldest months of the year. Under the assumption that most winter excess mortality is due to cold temperature, many previous studies have concluded that winter mortality will substantially decline in a warming climate. We analyzed whether and to what extent cold temperatures are associated with excess winter mortality across multiple cities and over multiple years within individual cities, using daily temperature and mortality data from 36 US cities (1985-2006) and 3 French cities (1971-2007). Comparing across cities, we found that excess winter mortality did not depend on seasonal temperature range, and was no lower in warmer vs. colder cities, suggesting that temperature is not a key driver of winter excess mortality. Using regression models within monthly strata, we found that variability in daily mortality within cities was not strongly influenced by winter temperature. Finally we found that inadequate control for seasonality in analyses of the effects of cold temperatures led to spuriously large assumed cold effects, and erroneous attribution of winter mortality to cold temperatures. Our findings suggest that reductions in cold-related mortality under warming climate may be much smaller than some have assumed. This should be of interest to researchers and policy makers concerned with projecting future health effects of climate change and developing relevant adaptation strategies.

  11. Detection of early warning signals of forest mortality in California (United States)

    Liu, Y.; Kumar, M.; Katul, G. G.; Porporato, A. M.


    Massive forest mortality was observed in California during the most recent drought. Owing to complex interactions of physiological mechanisms under stress, prediction of climate-induced forest mortality using dynamic global vegetation models remains fraught with uncertainty. Given that forest ecosystems approaching mortality tend to exhibit reduction in resilience, we evaluate the time-varying resilience from time series of satellite images to detect early warning signals (EWSs) of mortality. Four metrics of EWSs are used: (1) low greenness, (2) high empirical autocorrelation of greenness, (3) high autocorrelation inferred using a Bayesian dynamic linear model considering the influence of seasonality and climate conditions, and (4) low recovery rate inferred from the drift term in the Langevin equation describing stochastic dynamics. Spatial accuracy and lead-time of these EWSs are evaluated by comparing the EWSs against observed mortality from aerial surveys conducted by the US Forest Service. Our results show that most forested areas in California that underwent mortality exhibit a EWS with a lead time of three months to two years ahead of observed mortality. Notably, EWS is also detected in some areas without mortality, suggesting reduced resilience during drought. Furthermore, the influence of the previous drought (2007-2009) may have propagated into the recent drought (2012-2016) through reduced resilience, hence contributing to the massive forest mortality observed recently. Methodologies developed in this study for detection of EWS will improve the near-term predictability of forest mortality, thus providing crucial information for forest and water resource management.

  12. Factors contributing to amphibian road mortality in a wetland

    Directory of Open Access Journals (Sweden)

    Haijun GU, Qiang DAI, Qian WANG, Yuezhao WANG


    Full Text Available To understand road characteristics and landscape features associated with high road mortality of amphibians in Zoige Wetland National Nature Reserve, we surveyed road mortality along four major roads after rainfall in May and September 2007. Road mortality of three species, Rana kukunoris, Nanorana pleskei and Bufo minshanicus, was surveyed across 225 transects (115 in May and 110 in September. Transects were 100 m long and repeated every two kilometers along the four major roads. We used model averaging to assess factors that might determine amphibian road mortality. We recorded an average of 24.6 amphibian road mortalities per kilometer in May and 19.2 in September. Among road characteristics, road width was positively associated with road morality for R. kukunori and B. minshanicus. Traffic volume also increased the road mortality of B. minshanicus in September. Of the landscape features measured, area proportions of three types of grassland (wet, mesic and dry within 1 km of the roads, particularly that of wet grassland, significantly increased road mortality for R. kukunori and total mortality across all three species. To most effectively reduce road mortality of amphibians in the Zoige wetlands, we suggest better road design such as avoiding wet grasslands, minimizing road width, underground passes and traffic control measures. The implementation of public transit in the area would reduce traffic volume, and hence mortality [Current Zoology 57 (6: 768–774, 2011].

  13. Simulations of forest mortality in Colorado River basin (United States)

    Wei, L.; Xu, C.; Johnson, D. J.; Zhou, H.; McDowell, N.


    The Colorado River Basin (CRB) had experienced multiple severe forest mortality events under the recent changing climate. Such forest mortality events may have great impacts on ecosystem services and water budget of the watershed. It is hence important to estimate and predict the forest mortality in the CRB with climate change. We simulated forest mortality in the CRB with a model of plant hydraulics within the FATES (the Functionally Assembled Terrestrial Ecosystem Simulator) coupled to the DOE Earth System model (ACME: Accelerated Climate Model of Energy) at a 0.5 x 0.5 degree resolution. Moreover, we incorporated a stable carbon isotope (δ13C) module to ACME(FATE) and used it as a new predictor of forest mortality. The δ13C values of plants with C3 photosynthetic pathway (almost all trees are C3 plants) can indicate the water stress plants experiencing (the more intensive stress, the less negative δ13C value). We set a δ13C threshold in model simulation, above which forest mortality initiates. We validate the mortality simulations with field data based on Forest Inventory and Analysis (FIA) data, which were aggregated into the same spatial resolution as the model simulations. Different mortality schemes in the model (carbon starvation, hydraulic failure, and δ13C) were tested and compared. Each scheme demonstrated its strength and the plant hydraulics module provided more reliable simulations of forest mortality than the earlier ACME(FATE) version. Further testing is required for better forest mortality modelling.

  14. Tree mortality predicted from drought-induced vascular damage (United States)

    Anderegg, William R.L.; Flint, Alan L.; Huang, Cho-ying; Flint, Lorraine E.; Berry, Joseph A.; Davis, Frank W.; Sperry, John S.; Field, Christopher B.


    The projected responses of forest ecosystems to warming and drying associated with twenty-first-century climate change vary widely from resiliency to widespread tree mortality1, 2, 3. Current vegetation models lack the ability to account for mortality of overstorey trees during extreme drought owing to uncertainties in mechanisms and thresholds causing mortality4, 5. Here we assess the causes of tree mortality, using field measurements of branch hydraulic conductivity during ongoing mortality in Populus tremuloides in the southwestern United States and a detailed plant hydraulics model. We identify a lethal plant water stress threshold that corresponds with a loss of vascular transport capacity from air entry into the xylem. We then use this hydraulic-based threshold to simulate forest dieback during historical drought, and compare predictions against three independent mortality data sets. The hydraulic threshold predicted with 75% accuracy regional patterns of tree mortality as found in field plots and mortality maps derived from Landsat imagery. In a high-emissions scenario, climate models project that drought stress will exceed the observed mortality threshold in the southwestern United States by the 2050s. Our approach provides a powerful and tractable way of incorporating tree mortality into vegetation models to resolve uncertainty over the fate of forest ecosystems in a changing climate.

  15. Osteoporosis-Related Mortality: Time-Trends and Predictive Factors

    Directory of Open Access Journals (Sweden)

    Nelly Ziadé


    Full Text Available Osteoporosis is one of the leading causes of handicap worldwide and a major contributor to the global burden of diseases. In particular, osteoporosis is associated with excess mortality. We reviewed the impact of osteoporosis on mortality in a population by defining three categories: mortality following hip fractures, mortality following other sites of fractures, and mortality associated with low bone mineral density (BMD. Hip fractures, as well as other fractures at major sites are all associated with excess mortality, except at the forearm site. This excess mortality is higher during the first 3-6 months after the fracture and then declines over time, but remains higher than the mortality of the normal population up to 22 years after the fracture. Low BMD is also associated with high mortality, with hazard ratios of around 1.3 for every decrease in 1 standard deviation of bone density at 5 years, independently of fractures, reflecting a more fragile population. Finally predictors of mortality were identified and categorised in demographic known factors (age and male gender and in factors reflecting a poor general health status such as the number of comorbidities, low mental status, or level of social dependence. Our results indicate that the management of a patient with osteoporosis should include a multivariate approach that could be based on predictive models in the future.

    Full Text Available Background: Tuberculosis (TB is one of the main causes of morbidity and mortality in different societies. Understanding factors leading to death following diagnosis of TB is important to predict prognosis in TB patients. The aim of this study was to identify common risk factors associated with death in patients with an in-hospital diagnosis of TB, in a city in Iran with the highest prevalence and incidence of TB in the country. Materials and Methods: A retrospective study was conducted at a university-affiliated hospital, Zahedan, in the south-east of Iran, which is a referral center for TB. To identify factors leading to death, medical records of 715 patients ≥15 years old with pulmonary TB from February 2002 to February 2011 have been evaluated. Registered factors included smoking, human immune deficiency virus (HIV infection, using drugs, lung cancer, drug hepatitis following anti-TB medications, diabetes mellitus, previous TB treatment, anemia; and results of sputum smears. Univariate comparison and multiple logistic regression were performed to identify factors associated with mortality in TB patients. Results: Among 715 registered TB patients, 375 (52.5% patients were male; among those, 334 (53% were in the alive group and 41 (54% in the death group. Seventy-five (10.5% of the total number of TB patients died during TB treatment. The multivariate model showed that anemia (AOR: 19.8, 95% CI: 5.6-35.5, positive sputum smear (AOR: 13.4, 95% CI: 6.8-33.6, smoking (AOR: 12.9, 95% CI: 3.9-27.3, drug hepatitis (AOR: 12.3, 95% CI: 6.7-24.7, diabetes mellitus (AOR: 9.7, 95% CI: 2.9-32.0, drug use (AOR: 7.8, 95% CI: 2.4-25.5, and history of previous TB (AOR: 6.8, 95% CI: 2.2-21.3 were major risk factors for death in TB patients. Conclusion: Monitoring co-morbid conditions like diabetes mellitus and anemia are important to reduce death rate in TB patients. Preventive measures for smoking and drug addiction also play an important role to decrease

  17. Reduction of infant mortality in India. (United States)

    Kumar, V; Datta, N


    In India the infant mortality rate (IMR) registered an impressive decline during the first 5-6 decades of the 20th century, but in the last 30 years a significant decline has not been documented. The IMR continues to be in the range of 120-130/1000. In many developed countries it is reported as less than 20/1000. The World Health Organization (WHO) has recommended that by the year 2000 the IMR should be reduced to below 50/1000. India's government has set a target of 60/1000 to be reached by 2000. In Kerala this target has already been achieved. Several projects throughout India have indicated that this task can be accomplished. Many lessons can be learned from Kerala and the successful projects. 1 major constraint in information on IMR in India is the lack of uniformity and reliability in the system of recording vital events. Mere knowledge of IMR is insufficient for planning and execution of an appropriate intervention strategy. It is also important to understand the various causes of death. Based on the available information and a review of the literature, it is clear that 50% of the deaths in infancy occurred during the neonatal period. The common preventable causes of death in infancy identified are acute respiratory infections, acute diarrheal disease, low birth weight, protein energy malnutrition, tetanus neonatorum, and communicable diseases like measles, whooping cough, and typhoid. The high IMR can be reduced by general measures which can only be recommended as medium-term and longterm plans. These include an increase in the gross national product and female literacy, a decreasing birthrate, and an increasing capita food intake. At this time India is not experiencing rapid gains in any of these areas. Many of the strategies to reduce IMR have been reviewed objectively by Bhargava et al. Each strategy has merit, but, due to limited resources, it is essential to set priorities. The selection of priorities should be based on 4 basic questions: how common is

  20. Hydration, morbidity, and mortality in vulnerable populations. (United States)

    Maughan, Ronald J


    Both acute and chronic fluid deficits have been shown to be associated with a number of adverse health outcomes. At the extreme, deprivation of water for more than a few days inevitably leads to death, but even modest fluid deficits may precipitate adverse events, especially in young children, in the frail elderly and in those with poor health. Epidemiological studies have shown an association, although not necessarily a causal one, between a low habitual fluid intake and some chronic diseases, including urolithiasis, constipation, asthma, cardiovascular disease, diabetic hyperglycemia, and some cancers. Acute hypohydration may be a precipitating factor in a number of acute medical conditions in elderly persons. Increased mortality, especially in vulnerable populations, is commonly observed during periods of abnormally warm weather, with at least part of this effect due to failure to increase water intake, and this may have some important implications for those responsible for forward planning in healthcare facilities. © 2012 International Life Sciences Institute.

    We analyzed the risk in 2,743 atomic bomb survivors by using a new dosimetry system. From the database, we selected 2,743 exposed persons and a total of three times 2,743 age-matched controls who were living far from the center of the A-bomb radiation in Nagasaki at the time of the explosion and who were still alive in 1971. The mortalities from all causes for male subjects exposed were slightly lower than, or almost equal to, those of unexposed persons. Death from cancer, however, increased in both sexes after all levels of irradiation except in males exposed to 0.01-0.49 Gy. In males, the risk was showed significant reduction in death from all diseases other than cancer classified according to 0.31-0.40 Gy. (author)

    Jensen, Tina Kold; Bostofte, Erik; Jacobsen, Rune

    Objective: Over recent decades a possible decrease in semen quality and an increase in the incidence of testicular cancer have been reported. In addition, men with poor semen quality have been reported to be at increased risk of developing testicular cancer whereas the risk of other cancers...... is not increased. The long-term survival of men with poor semen quality is, however, unknown. We therefore studied the associations between semen characteristics and subsequent mortality. Back to Top Material and Methods: The Copenhagen Sperm Analysis Laboratory is one of several public semen analysis laboratories...... in Denmark and examines semen samples mostly from men in the area of Copenhagen. Men are referred to the clinic by general practitioners and urologists, and the investigations are paid for through the public health system. A total of 34.442 men had a semen analysis done at the laboratory during 1963 to 1995...

  5. Morbidity and mortality associated with obstetric hysterectomy

    International Nuclear Information System (INIS)

    Shaikh, N.B.; Shaikh, S.; Shaikh, J.M.


    Background: Obstetric hysterectomy still complicates a substantial number of pregnancies in third world countries and is a significant cause of obstetric morbidity and mortality. This study was carried out to evaluate in our setup the frequency of obstetric hysterectomy, its indication, risk factors, complication, morbidity, mortality and avoidable factors. Methods: A descriptive study of all patients who under went obstetric hysterectomy was conducted from May 1, 2004 to October 31, 2005 at Gynaecology and Obstetric Unit-II, III of Liaquat University of Medical and Health Science Hospital, Hyderabad. After collecting the data on pre-designed proforma the data was fed to SPSS in the form of frequency distribution tables and percentages were calculated. Statistical analysis of data was performed by using Chi-square test. The level of significance was taken as p<0.05. Results: During the study time period there were total 6495 deliveries and 41 cases of obstetric hysterectomy were identified, giving a frequency of 0.63% or 1 in 158 deliveries. Most of patients were from rural areas (82.92%), un-booked 73.17%), uneducated (95%), lower socio economical class (92.69%), 25-29 years age (48.78%) multiparae (56.10%), have to travel a distance of <100 km to reach hospital and referred late (51%) by health care providers (doctors). Majority of hysterectomies were performed due to ruptured uteri (51.21%). There were 5 maternal and 26 perinatal deaths; all were due to severity of conditions necessitating hysterectomy. Conclusion: Incidence of obstetric hysterectomy in our woman is very high. The reason being many avoidable factors such as high parity, inadequate maternity and family planning services, lack of proper referral system, un-booked status, mismanaged labour, illiteracy on the part of woman herself, family and health care providers are not taken care of during pregnancy, labour and puerperium.

    Cardiac tumors are rare, mostly benign with high embolic potential. To correlate the histological type of cardiac masses with their embolic potential, implantation site and long term follow up in patients undergoing surgery. Between January 1986 and December 2011, we retrospectively analyzed 185 consecutive patients who underwent excision of intracardiac mass (119 females, mean age 48±20 years). In 145 patients, the left atrium was the origin site. 72% were asymptomatic and prior embolization was often observed (19.8%). The diagnosis was established by echocardiography, magnetic resonance and histological examination. Most tumors were located in the left side of the heart. Myxoma was the most common (72.6%), followed by fibromas (6.9%), thrombi (6.4%) and sarcomas (6.4%). Ranging from 0.6cm to 15cm (mean 4.6 ± 2.5cm) 37 (19.8%) patients had prior embolization, stroke 10.2%, coronary 4.8%, peripheral 4.3% 5.4% of hospital death, with a predominance of malignant tumors (40% p < 0.0001). The histological type was a predictor of mortality (rhabdomyomas and sarcomas p = 0.002) and embolic event (sarcoma, lipoma and fibroelastoma p = 0.006), but not recurrence. Tumor size, atrial fibrillation, cavity and valve impairment were not associated with the embolic event. During follow-up (mean 80±63 months), there were 2 deaths (1.1%) and two recurrences 1 and 11 years after the operation, to the same cavity. Most tumors were located in the left side of the heart. The histological type was predictor of death and preoperative embolic event, while the implantation site carries no relation with mortality or to embolic event.

  7. Mortality of British radiologists. A lecture Note+

    Doll, R.


    The precautions introduced after the first 23 years experience of the use of x-rays for medical diagnosis proved adequate to eliminate the acute hazards of exposure, but it was much longer before it was realized that small doses that did not produce any acute effect could increase the risk of cancer. British radiologists who took up the specialty at different periods have, therefore, been studied to see if the risk has now been adequately controlled. Four groups have been studied starting respectively before 1921, in 1921-34, 1935-54, and 1955-77, corresponding approximately to periods when different limits of exposure were applied. Altogether 2698 male radiologists have been identified and all but 27 followed successfully to emigration, death, or survival to January 1 st 1997. Of the 1198 who had died, 228 are known to have died of cancer. Two problems arise in evaluating the carcinogenic hazard to which they were exposed: the assessment of the doses received and the selection of an appropriate control group with which to compare their mortality. The most appropriate comparison group would seem to be medical practitioners in general. In comparison with them, radiologists entering in the first 3 periods had increased risks of death from cancer though appreciably less than would have been predicted from the expected effect of the radiation they had received. Those who joined in the latest period had a relatively reduced risk, irrespective of any effect of the small dose of radiation they are likely to have received. Independent evidence suggests, however, that since 1951 radiologists have smoked less than other doctors and the lower than predicted risk in the groups exposed since 1920 is limited to smoking related cancers, the mortality from other cancers being higher than in doctors generally. In assessing the risk of occupational exposure to radiation, life-style has to be taken into consideration, as well as dose of radiation. (author)

    Japanese radiological technologists occupationally have chances of receiving low doses of ionizing radiation. A cohort study was started on them in 1981, since knowledge of the mortality and health of this population is pertinent to the evaluation of the risk from low-level exposure to radiation. A sampling of 2028 Japanese radiological technologists born before 1933 was followed from 1969 to 1982. All deaths were confirmed by checking copies of family registers and the causes were obtained from death certificates. The deaths observed within this group were compared with the expected number of deaths from major causes as estimated using the Japanese life table of 1975. The number of deaths from all causes, 131, was less than the expected 182.39, a difference that is statistically significant at the 1% level. The observed number of deaths from all malignant neoplasms, 51, was slightly larger than that of the expected 48.94, although the difference was not statistically significant. However, there was a significant excess of observed deaths from brain tumour and malignant neoplasms of male urogenital organs in comparison with expected deaths. Deaths from anaemia also significantly exceeded the expected level. The relationship between dose level and cause of death as adjusted by age at death and first year of employment was investigated using contingency table analysis. Accumulated occupational doses were estimated for 599 of the population of 2028. The relative risk of mortality ratios for all causes of death and cancer of all sites in four dose categories, <50, 50-74, 75-99 and 100+ rad, increased with dose but the statistical tests did not show any significant association. Observation and analysis should be continued to check our present findings further and obtain more complete data. (author)

  9. Reflections on the maternal mortality millennium goal. (United States)

    Lawson, Gerald W; Keirse, Marc J N C


    Nearly every 2 minutes, somewhere in the world, a woman dies because of complications of pregnancy and childbirth. Every such death is an overwhelming catastrophe for everyone confronted with it. Most deaths occur in developing countries, especially in Africa and southern Asia, but a significant number also occur in the developed world. We examined the available data on the progress and the challenges to the United Nations' fifth Millennium Development Goal of achieving a 75 percent worldwide reduction in the maternal mortality by 2015 from what it was in 1990. Some countries, such as Belarus, Egypt, Estonia, Honduras, Iran, Lithuania, Malaysia, Romania, Sri Lanka and Thailand, are likely to meet the target by 2015. Many poor countries with weak health infrastructures and high fertility rates are unlikely to meet the goal. Some, such as Botswana, Cameroon, Chad, Congo, Guyana, Lesotho, Namibia, Somalia, South Africa, Swaziland and Zimbabwe, had worse maternal mortality ratios in 2010 than in 1990, partially because of wars and civil strife. Worldwide, the leading causes of maternal death are still hemorrhage, hypertension, sepsis, obstructed labor, and unsafe abortions, while indirect causes are gaining in importance in developed countries. Maternal death is especially distressing if it was potentially preventable. However, as there is no single cause, there is no silver bullet to correct the problem. Many countries also face new challenges as their childbearing population is growing in age and in weight. Much remains to be done to make safe motherhood a reality. © 2013, Copyright the Authors, Journal compilation © 2013, Wiley Periodicals, Inc.

  10. Diabetes and perinatal mortality in twin pregnancies.

    Directory of Open Access Journals (Sweden)

    Zhong-Cheng Luo

    Full Text Available BACKGROUND: Diabetes in pregnancy has been associated with a paradoxically reduced risk of neonatal death in twin pregnancies. Risk "shift" may be a concern in that the reduction in neonatal deaths may be due to an increase in fetal deaths (stillbirths. This study aimed to clarify the impact of diabetes on the risk of perinatal death (neonatal death plus stillbirth in twin pregnancies. METHODS: This was a retrospective cohort study of twin births using the largest available dataset on twin births (the U.S. matched multiple birth data 1995-2000; 19,676 neonates from diabetic pregnancies, 541,481 from non-diabetic pregnancies. Cox proportional hazard models were applied to estimate the adjusted hazard ratios (aHR of perinatal death accounting for twin cluster-level dependence. RESULTS: Comparing diabetic versus non-diabetic twin pregnancies, overall perinatal mortality rate was counterintuitively lower [2.1% versus 3.3%, aHR 0.70 (95% confidence intervals 0.63-0.78]. Individually, both stillbirth and neonatal mortality rates were lower in diabetic pregnancies, but we identified significant differences by gestational age and birth weight. Diabetes was associated with a survival benefit in pregnancies completed before 32 weeks [aHR 0.55 (0.48-0.63] or with birth weight =2500 g [aHR 2.20 (1.55-3.13]. CONCLUSIONS: Diabetes in pregnancy appears to be "protective" against perinatal death in twin pregnancies ending in very preterm or very low birth weight births. Prospective studies are required to clarify whether these patterns of risk are real, or they are artifacts of unmeasured confounders. Additional data correlating these outcomes with the types of diabetes in pregnancy are also needed to distinguish the effects of pre-gestational vs. gestational diabetes.

  11. Prediction of mortality based on facial characteristics

    Directory of Open Access Journals (Sweden)

    Arnaud Delorme


    Full Text Available Recent studies have shown that characteristics of the face contain a wealth of information about health, age and chronic clinical conditions. Such studies involve objective measurement of facial features correlated with historical health information. But some individuals also claim to be adept at gauging mortality based on a glance at a person’s photograph. To test this claim, we invited 12 such individuals to see if they could determine if a person was alive or dead based solely on a brief examination of facial photographs. All photos used in the experiment were transformed into a uniform gray scale and then counterbalanced across eight categories: gender, age, gaze direction, glasses, head position, smile, hair color, and image resolution. Participants examined 404 photographs displayed on a computer monitor, one photo at a time, each shown for a maximum of 8 seconds. Half of the individuals in the photos were deceased, and half were alive at the time the experiment was conducted. Participants were asked to press a button if they thought the person in a photo was living or deceased. Overall mean accuracy on this task was 53.8%, where 50% was expected by chance (p < 0.004, two-tail. Statistically significant accuracy was independently obtained in 5 of the 12 participants. We also collected 32-channel electrophysiological recordings and observed a robust difference between images of deceased individuals correctly vs. incorrectly classified in the early event related potential at 100 ms post-stimulus onset. Our results support claims of individuals who report that some as-yet unknown features of the face predict mortality. The results are also compatible with claims about clairvoyance and warrants further investigation.

  12. Continuing increase in mesothelioma mortality in Britain. (United States)

    Peto, J; Hodgson, J T; Matthews, F E; Jones, J R


    Mesothelioma is closely related to exposure to asbestos, and mesothelioma mortality can be taken as an index of past exposure to asbestos in the population. We analysed mesothelioma mortality since 1968 to assess the current state of the mesothelioma epidemic, and to predict its future course. We found that rates of mesothelioma in men formed a clear pattern defined by age and date of birth. Rates rose steeply with age showing a very similar pattern in all five-year birth cohorts. By date of birth, rates increased from mid-1893 to mid-1948, and then fell. Relative to the 1943-48 cohort, the risk for the 1948-53 cohort is 0.79 and for the 1953-58 cohort 0.48. Despite these falls, if the age profile of rates for these cohorts follows the pattern of past cohorts, their predicted lifetime mesothelioma risks will be 1.3%, 1.0%, and 0.6%. Combining projections for all cohorts results in a peak of annual male mesothelioma deaths in about the year 2020 of between 2700 and 3300 deaths. If diagnostic trend is responsible for a 20% growth in recorded cases every 5 years--an extreme but arguable case--and if this trend has now ceased, the peak of annual male deaths will be reduced to 1300, reached around the year 2010. Analysis of occupations recorded on death certificates indicate that building workers, especially plumbers and gas fitters, carpenters and electricians are the largest high-risk group. These data indicate that mesothelioma deaths will continue to increase for at least 15 and more likely 25 years. For the worst affected cohorts--men born in the 1940s--mesothelioma may account for around 1% of all deaths. Asbestos exposure at work in construction and building maintenance will account for a large proportion of these deaths, and it is important that such workers should be aware of the risks and take appropriate precautions.

  13. Association between periodontitis and mortality in stages 3-5 chronic kidney disease: NHANES III and linked mortality study. (United States)

    Sharma, Praveen; Dietrich, Thomas; Ferro, Charles J; Cockwell, Paul; Chapple, Iain L C


    Periodontitis may add to the systemic inflammatory burden in individuals with chronic kidney disease (CKD), thereby contributing to an increased mortality rate. This study aimed to determine the association between periodontitis and mortality rate (all-cause and cardiovascular disease-related) in individuals with stage 3-5 CKD, hitherto referred to as "CKD". Survival analysis was carried out using the Third National Health and Nutrition Examination Survey (NHANES III) and linked mortality data. Cox proportional hazards regression was employed to assess the association between periodontitis and mortality, in individuals with CKD. This association was compared with the association between mortality and traditional risk factors in CKD mortality (diabetes, hypertension and smoking). Of the 13,784 participants eligible for analysis in NHANES III, 861 (6%) had CKD. The median follow-up for this cohort was 14.3 years. Adjusting for confounders, the 10-year all-cause mortality rate for individuals with CKD increased from 32% (95% CI: 29-35%) to 41% (36-47%) with the addition of periodontitis. For diabetes, the 10-year all-cause mortality rate increased to 43% (38-49%). There is a strong, association between periodontitis and increased mortality in individuals with CKD. Sources of chronic systemic inflammation (including periodontitis) may be important contributors to mortality in patients with CKD. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Poudel, Dilli Ram; Jayakumar, Divya; Danve, Abhijeet; Sehra, Shiv Tej; Derk, Chris T


    Scleroderma (systemic sclerosis) is an autoimmune rheumatic disorder that is characterized by fibrosis, vascular dysfunction, and autoantibody production that involves most visceral organs. It is characterized by a high morbidity and mortality rate, mainly due to disease-related complications. Epidemiological data describing mortality and survival in this population have been based on both population and observational studies. Multiple clinical and non-clinical factors have been found to predict higher likelihood of death among thepatients. Here, we do an extensive review of the available literature, utilizing the PubMed database, to describe scleroderma and non-scleroderma related determinants of mortality in this population. We found that even though the mortality among the general population has declined, scleroderma continues to carry a very high morbidity and mortality rate, however we have made some slow progress in improving the mortality among scleroderma patients over the last few decades.

    Infectious livestock diseases remain a major threat to attaining food security and are a source of economic and livelihood losses for people dependent on livestock for their livelihood. Knowledge of the vital infectious diseases that account for the majority of deaths is crucial in determining disease control strategies and in the allocation of limited funds available for disease control. Here we have estimated the mortality rates in zebu cattle raised in a smallholder mixed farming system during their first year of life, identified the periods of increased risk of death and the risk factors for calf mortality, and through analysis of post-mortem data, determined the aetiologies of calf mortality in this population. A longitudinal cohort study of 548 zebu cattle was conducted between 2007 and 2010. Each calf was followed during its first year of life or until lost from the study. Calves were randomly selected from 20 sub-locations and recruited within a week of birth from different farms over a 45 km radius area centered on Busia in the Western part of Kenya. The data comprised of 481.1 calf years of observation. Clinical examinations, sample collection and analysis were carried out at 5 week intervals, from birth until one year old. Cox proportional hazard models with frailty terms were used for the statistical analysis of risk factors. A standardized post-mortem examination was conducted on all animals that died during the study and appropriate samples collected. The all-cause mortality rate was estimated at 16.1 (13.0-19.2; 95% CI) per 100 calf years at risk. The Cox models identified high infection intensity with Theileria spp., the most lethal of which causes East Coast Fever disease, infection with Trypanosome spp., and helminth infections as measured by Strongyle spp. eggs per gram of faeces as the three important infections statistically associated with infectious disease mortality in these calves. Analysis of post-mortem data identified East Coast Fever as

    Kuehn, Rebecca; Fong, James; Taylor, Richard; Gyaneshwar, Rajanishwar; Carter, Karen


    Previous studies indicate that cervical cancer is the second most frequent cancer and most common cause of cancer mortality among women in Fiji. There is little published data on the epidemiology of cervical cancer in Pacific countries. To determine the incidence 2003-2009 of, and mortality 2003-2008 from, cervical cancer by ethnicity and period in Fiji, identify evidence of secular change and relate these data to other Pacific countries, Australia and New Zealand. Counts of incident cervical cancer cases (2003-2009) and unit record mortality data (2003-2008) from the Fiji Ministry of Health were used to calculate age-standardised (to the WHO World Population) cervical cancer incidence and mortality rates, and cervical or uterine cancer mortality rates, by ethnicity, with 95% confidence intervals. On the basis of comparison of cervical cancer mortality with cervical or uterine cancer mortality in Fiji with similar populations, misclassification of cervical cancer deaths is unlikely. There is no evidence of secular change in cervical cancer incidence and mortality rates for the study period. For women of all ages and ethnicities, the age-standardised incidence rate of cervical cancer (2003-2009) was 27.6 per 100,000 (95% CI 25.4-29.8) and the age-standardised mortality rate (2003-2008) was 23.9 per 100,000 (95% CI 21.5-26.4). The mortality/incidence ratio was 87%. Fijians had statistically significant higher age-standardised incidence and mortality rates than Indians. Fiji has one of the highest estimated rates of cervical cancer incidence and mortality in the Pacific region. Cervical cancer screening in Fiji needs to be expanded and strengthened. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

  19. Projecting UK mortality using Bayesian generalised additive models


    Hilton, Jason; Dodd, Erengul; Forster, Jonathan; Smith, Peter W.F.


    Forecasts of mortality provide vital information about future populations, with implications for pension and health-care policy as well as for decisions made by private companies about life insurance and annuity pricing. This paper presents a Bayesian approach to the forecasting of mortality that jointly estimates a Generalised Additive Model (GAM) for mortality for the majority of the age-range and a parametric model for older ages where the data are sparser. The GAM allows smooth components...

  20. Endogenous fishing mortalities: a state-space bioeconomic model




    A methodology that endogenously determines catchability functions that link fishing mortality with contemporaneous stock abundance is presented. We consider a stochastic age-structured model for a fishery composed by a number of fishing units (fleets, vessels or métiers) that optimally select the level of fishing effort to be applied considering total mortalities as given. The introduction of a balance constrain which guarantees that total mortality is equal to the sum of individual fishing m...

  1. Siberian Pine Decline and Mortality in Southern Siberian Mountains (United States)

    Kharuk, V. I.; Im, S. T.; Oskorbin, P. A.; Petrov, I. A.; Ranson, K. J.


    The causes and resulting spatial patterns of Siberian pine mortality in eastern Kuznetzky Alatau Mountains, Siberia were analyzed based on satellite (Landsat, MODIS) and dendrochronology data. Climate variables studied included temperature, precipitation and Standardized Precipitation-Evapotranspiration Index (SPEI) drought index. Landsat data analysis showed that stand mortality was first detected in the year 2006 at an elevation of 650 m, and extended up to 900 m by the year 2012. Mortality was accompanied by a decrease in MODIS derived vegetation index (EVI).. The area of dead stands and the upper mortality line were correlated with increased drought. The uphill margin of mortality was limited by elevational precipitation gradients. Dead stands (i.e., >75% tree mortality) were located mainly on southern slopes. With respect to slope, mortality was observed within a 7 deg - 20 deg range with greatest mortality occurring on convex terrain. Tree radial incrementmeasurements correlate and were synchronous with SPEI (r sq = 0.37, r(sub s) = 80). Increasing synchrony between tree ring growth and SPEI indicates that drought has reduced the ecological niche of Siberian pine. The results also showed the primary role of drought stress on Siberian pine mortality. A secondary role may be played by bark beetles and root fungi attacks. The observed Siberian pine mortality is part of a broader phenomenon of "dark needle conifers" (DNC, i.e., Siberian pine, fir and spruce) decline and mortality in European Russia, Siberia, and the Russian Far East. All locations of DNC decline coincided with areas of observed drought increase. The results obtained are one of the first observations of drought-induced decline and mortality of DNC at the southern border of boreal forests. Meanwhile if model projections of increased aridity are correct DNC, within the southern part of its range may be replaced by drought-resistant Pinus silvestris and Larix sibirica.


    Berwick, Marianne; Pestak, Claire; Thomas, Nancy


    Solar UV radiation (UVR) exposure is clearly associated with increased mortality from nonmelanoma skin cancer—usually squamous cell carcinoma. However, the association with cutaneous melanoma is unclear from the evidence in ecologic studies and several analytic studies have conflicting results regarding the effect of high levels of intermittent UV exposure prior to diagnosis on mortality. Understanding this conundrum is critical to present coherent public health messages and to improve the mortality rates from melanoma. PMID:25207375

  3. Relation between temperature and mortality in thirteen Spanish cities


    Iñiguez, Carmen; Ballester, Ferran; Ferrándiz, Juan; Pérez Hoyos, Santiago; Sáez Zafra, Marc; López Estudillo, Antonio


    In this study we examined the shape of the association between temperature and mortality in 13 Spanish cities representing a wide range of climatic and socio-demographic conditions. The temperature value linked with minimum mortality (MMT) and the slopes before and after the turning point (MMT) were calculated. Most cities showed a V-shaped temperature-mortality relationship. MMTs were generally higher in cities with warmer climates. Cold and heat effects also depended on climate: effects wer...

  4. Mortality data in the age of drones ‡. (United States)

    Carruthers, Elspeth


    Mortality data plays an essential role in shaping humanitarian, legal and ethical responses to conflict situations. The rise of drone warfare poses new questions regarding the accuracy and reliability of mortality data in conflict. This article examines some of the methodological and political challenges to collecting mortality data in drone warfare, and how the way in which drones are framed in public discourse contributes to these challenges.

  5. Cancer mortality among immigrant populations in Ontario, 1969 through 1973.


    Newman, A. M.; Spengler, R. F.


    Ontario is home to a sizeable, recently established immigrant population whose cancer mortality has until now remained unexamined. The province's six largest immigrant groups (British, Italian, German, Dutch, Polish and Soviet) were investigated to compare their cancer mortality experience with that prevailing in Ontario and in their countries of birth for the period 1969 through 1973. Standardized mortality ratios (SMRs) were computed from data from Statistics Canada and the World Health Org...

  6. Community variations in infant and child mortality in Peru.


    Edmonston, B; Andes, N


    Data from the national Peru Fertility Survey are used to estimate infant and childhood mortality ratios, 1968--77, for 124 Peruvian communities, ranging from small Indian hamlets in the Andes to larger cities on the Pacific coast. Significant mortality variations are found: mortality is inversely related to community population size and is higher in the mountains than in the jungle or coast. Multivariate analysis is then used to assess the influence of community population size, average femal...

  9. Modeled Urea Distribution Volume and Mortality in the HEMO Study (United States)

    Greene, Tom; Depner, Thomas A.; Levin, Nathan W.; Chertow, Glenn M.


    Summary Background and objectives In the Hemodialysis (HEMO) Study, observed small decreases in achieved equilibrated Kt/Vurea were noncausally associated with markedly increased mortality. Here we examine the association of mortality with modeled volume (Vm), the denominator of equilibrated Kt/Vurea. Design, setting, participants, & measurements Parameters derived from modeled urea kinetics (including Vm) and blood pressure (BP) were obtained monthly in 1846 patients. Case mix–adjusted time-dependent Cox regressions were used to relate the relative mortality hazard at each time point to Vm and to the change in Vm over the preceding 6 months. Mixed effects models were used to relate Vm to changes in intradialytic systolic BP and to other factors at each follow-up visit. Results Mortality was associated with Vm and change in Vm over the preceding 6 months. The association between change in Vm and mortality was independent of vascular access complications. In contrast, mortality was inversely associated with V calculated from anthropometric measurements (Vant). In case mix–adjusted analysis using Vm as a time-dependent covariate, the association of mortality with Vm strengthened after statistical adjustment for Vant. After adjustment for Vant, higher Vm was associated with slightly smaller reductions in intradialytic systolic BP and with risk factors for mortality including recent hospitalization and reductions in serum albumin concentration and body weight. Conclusions An increase in Vm is a marker for illness and mortality risk in hemodialysis patients. PMID:21511841

  10. Spatial pattern and temporal trend of mortality due to tuberculosis

    Ana Angélica Rêgo de Queiroz


    Full Text Available ABSTRACT Objectives: To describe the epidemiological profile of mortality due to tuberculosis (TB, to analyze the spatial pattern of these deaths and to investigate the temporal trend in mortality due to tuberculosis in Northeast Brazil. Methods: An ecological study based on secondary mortality data. Deaths due to TB were included in the study. Descriptive statistics were calculated and gross mortality rates were estimated and smoothed by the Local Empirical Bayesian Method. Prais-Winsten’s regression was used to analyze the temporal trend in the TB mortality coefficients. The Kernel density technique was used to analyze the spatial distribution of TB mortality. Results: Tuberculosis was implicated in 236 deaths. The burden of tuberculosis deaths was higher amongst males, single people and people of mixed ethnicity, and the mean age at death was 51 years. TB deaths were clustered in the East, West and North health districts, and the tuberculosis mortality coefficient remained stable throughout the study period. Conclusions: Analyses of the spatial pattern and temporal trend in mortality revealed that certain areas have higher TB mortality rates, and should therefore be prioritized in public health interventions targeting the disease.

  11. A new drought tipping point for conifer mortality (United States)

    Kolb, Thomas E.


    (Huang et al 2015 Environ. Res. Lett. 10 024011) present a method for predicting mortality of ponderosa pine (Pinus ponderosa) and pinyon pine (Pinus edulis) in the Southwestern US during severe drought based on the relationship between the standardized precipitation-evapotranspiration index (SPEI) and annual tree ring growth. Ring growth was zero when SPEI for September to July was -1.64. The threshold SPEI of -1.64 was successful in distinguishing areas with high tree mortality during recent severe drought from areas with low mortality, and is proposed to be a tipping point of drought severity leading to tree mortality. Below, I discuss this work in more detail.

  12. Climate change, humidity, and mortality in the United States (United States)

    Barreca, Alan I.


    This paper estimates the effects of humidity and temperature on mortality rates in the United States (c. 1973–2002) in order to provide an insight into the potential health impacts of climate change. I find that humidity, like temperature, is an important determinant of mortality. Coupled with Hadley CM3 climate-change predictions, I project that mortality rates are likely to change little on the aggregate for the United States. However, distributional impacts matter: mortality rates are likely to decline in cold and dry areas, but increase in hot and humid areas. Further, accounting for humidity has important implications for evaluating these distributional effects. PMID:25328254

  13. Mortality of veteran participants in the crossroads nuclear test

    Johnson, J.C.; Thaul, S.; Page, W.F.


    Operation CROSSROADS, conducted at Bikini Atoll in 1946, was the first post World War II test of nuclear weapons. Mortality experience of 40,000 military veteran participants in CROSSROADS was compared to that of a similar cohort of nonparticipating veterans. All-cause mortality of the participants was slightly increased over nonparticipants by 5% (p < .001). Smaller increases in participant mortality for all malignancies (1.4%, p = 0.26) or leukemia (2.0%, p = 0.9) were not statistically significant. These results do not support a hypothesis that radiation had increased participant cancer mortality over that of nonparticipants. 8 refs

  14. Age structure and mortality of walleyes in Kansas reservoirs: Use of mortality caps to establish realistic management objectives (United States)

    Quist, M.C.; Stephen, J.L.; Guy, C.S.; Schultz, R.D.


    Age structure, total annual mortality, and mortality caps (maximum mortality thresholds established by managers) were investigated for walleye Sander vitreus (formerly Stizostedion vitreum) populations sampled from eight Kansas reservoirs during 1991-1999. We assessed age structure by examining the relative frequency of different ages in the population; total annual mortality of age-2 and older walleyes was estimated by use of a weighted catch curve. To evaluate the utility of mortality caps, we modeled threshold values of mortality by varying growth rates and management objectives. Estimated mortality thresholds were then compared with observed growth and mortality rates. The maximum age of walleyes varied from 5 to 11 years across reservoirs. Age structure was dominated (???72%) by walleyes age 3 and younger in all reservoirs, corresponding to ages that were not yet vulnerable to harvest. Total annual mortality rates varied from 40.7% to 59.5% across reservoirs and averaged 51.1% overall (SE = 2.3). Analysis of mortality caps indicated that a management objective of 500 mm for the mean length of walleyes harvested by anglers was realistic for all reservoirs with a 457-mm minimum length limit but not for those with a 381-mm minimum length limit. For a 500-mm mean length objective to be realized for reservoirs with a 381-mm length limit, managers must either reduce mortality rates (e.g., through restrictive harvest regulations) or increase growth of walleyes. When the assumed objective was to maintain the mean length of harvested walleyes at current levels, the observed annual mortality rates were below the mortality cap for all reservoirs except one. Mortality caps also provided insight on management objectives expressed in terms of proportional stock density (PSD). Results indicated that a PSD objective of 20-40 was realistic for most reservoirs. This study provides important walleye mortality information that can be used for monitoring or for inclusion into

  15. Onset of mortality increase with age and age trajectories of mortality from all diseases in the four Nordic countries

    Dolejs J


    Full Text Available Josef Dolejs,1 Petra Marešová2 1Department of Informatics and Quantitative Methods, 2Department of Economics, Faculty of Informatics and Management, University of Hradec Králové, Hradec Králové, Czech Republic Background: The answer to the question “At what age does aging begin?” is tightly related to the question “Where is the onset of mortality increase with age?” Age affects mortality rates from all diseases differently than it affects mortality rates from nonbiological causes. Mortality increase with age in adult populations has been modeled by many authors, and little attention has been given to mortality decrease with age after birth.Materials and methods: Nonbiological causes are excluded, and the category “all diseases” is studied. It is analyzed in Denmark, Finland, Norway, and Sweden during the period 1994–2011, and all possible models are screened. Age trajectories of mortality are analyzed separately: before the age category where mortality reaches its minimal value and after the age category.Results: Resulting age trajectories from all diseases showed a strong minimum, which was hidden in total mortality. The inverse proportion between mortality and age fitted in 54 of 58 cases before mortality minimum. The Gompertz model with two parameters fitted as mortality increased with age in 17 of 58 cases after mortality minimum, and the Gompertz model with a small positive quadratic term fitted data in the remaining 41 cases. The mean age where mortality reached minimal value was 8 (95% confidence interval 7.05–8.95 years. The figures depict an age where the human population has a minimal risk of death from biological causes.Conclusion: Inverse proportion and the Gompertz model fitted data on both sides of the mortality minimum, and three parameters determined the shape of the age–mortality trajectory. Life expectancy should be determined by the two standard Gompertz parameters and also by the single parameter in

    Preston, D.L.; Kato, H.; Kopecky, K.; Fujita, S.


    This study extends an earlier one by 4 years (1979-1982) and includes mortality data on 11,393 additional Nagasaki survivors. Significant dose responses are observed for leukemia, multiple myeloma, and cancers of the lung, female breast, stomach, colon, esophagus, and urinary tract. Due to diagnostic difficulties, results for liver and ovarian cancers, while suggestive of significant dose responses, do not provide convincing evidence for radiogenic effects. No significant dose responses are seen for cancers of the gallbladder, prostate, rectum, pancreas, or uterus, or for lymphoma. For solid tumors, largely due to sex-specific differences in the background rates, the relative risk of radiation-induced mortality is greater for women than for men. For nonleukemic cancers the relative risk seen in those who were young when exposed has decreased with time, while the smaller risks for those who were older at exposure have tended to increase. While the absolute excess risks of radiation-induced mortality due to nonleukemic cancer have increased with time for all age-at-exposure groups, both excess and relative risks of leukemia have generally decreased with time. For leukemia, the rate of decrease in risk and the initial level of risk are inversely related to age at exposure

  17. National estimates for maternal mortality: an analysis based on the WHO systematic review of maternal mortality and morbidity

    Directory of Open Access Journals (Sweden)

    Gülmezoglu A Metin


    Full Text Available Abstract Background Despite the worldwide commitment to improving maternal health, measuring, monitoring and comparing maternal mortality estimates remain a challenge. Due to lack of data, international agencies have to rely on mathematical models to assess its global burden. In order to assist in mapping the burden of reproductive ill-health, we conducted a systematic review of incidence/prevalence of maternal mortality and morbidity. Methods We followed the standard methodology for systematic reviews. This manuscript presents nationally representative estimates of maternal mortality derived from the systematic review. Using regression models, relationships between study-specific and country-specific variables with the maternal mortality estimates are explored in order to assist further modelling to predict maternal mortality. Results Maternal mortality estimates included 141 countries and represent 78.1% of the live births worldwide. As expected, large variability between countries, and within regions and subregions, is identified. Analysis of variability according to study characteristics did not yield useful results given the high correlation with each other, with development status and region. A regression model including selected country-specific variables was able to explain 90% of the variability of the maternal mortality estimates. Among all country-specific variables selected for the analysis, three had the strongest relationships with maternal mortality: proportion of deliveries assisted by a skilled birth attendant, infant mortality rate and health expenditure per capita. Conclusion With the exception of developed countries, variability of national maternal mortality estimates is large even within subregions. It seems more appropriate to study such variation through differentials in other national and subnational characteristics. Other than region, study of country-specific variables suggests infant mortality rate, skilled birth

    Although interests in assessing the relationship between temperature and mortality have arisen due to climate change, relatively few data are available on lag structure of temperature-mortality relationship, particularly in the Southern Hemisphere. This study identified the lag effects of mean temperature on mortality among age groups and death categories using polynomial distributed lag models in Brisbane, Australia, a subtropical city, 1996-2004. For a 1 deg. C increase above the threshold, the highest percent increase in mortality on the current day occurred among people over 85 years (7.2% (95% CI: 4.3%, 10.2%)). The effect estimates among cardiovascular deaths were higher than those among all-cause mortality. For a 1 deg. C decrease below the threshold, the percent increases in mortality at 21 lag days were 3.9% (95% CI: 1.9%, 6.0%) and 3.4% (95% CI: 0.9%, 6.0%) for people aged over 85 years and with cardiovascular diseases, respectively. These findings may have implications for developing intervention strategies to reduce and prevent temperature-related mortality. - Highlights: > A longer lag effects in cold days and shorter lag effects in hot days. > The very old people were most vulnerable to temperature stress. > The cardiovascular mortality was also sensitive to the temperature variation. - In Brisbane, the lag effects lasted longer for cold temperatures, and shorter for hot temperatures. Elderly people and cardiovascular mortality were vulnerable to temperature stress.

  19. Out of control mortality matters: the effect of perceived uncontrollable mortality risk on a health-related decision. (United States)

    Pepper, Gillian V; Nettle, Daniel


    Prior evidence from the public health literature suggests that both control beliefs and perceived threats to life are important for health behaviour. Our previously presented theoretical model generated the more specific hypothesis that uncontrollable, but not controllable, personal mortality risk should alter the payoff from investment in health protection behaviours. We carried out three experiments to test whether altering the perceived controllability of mortality risk would affect a health-related decision. Experiment 1 demonstrated that a mortality prime could be used to alter a health-related decision: the choice between a healthier food reward (fruit) and an unhealthy alternative (chocolate). Experiment 2 demonstrated that it is the controllability of the mortality risk being primed that generates the effect, rather than mortality risk per se. Experiment 3 showed that the effect could be seen in a surreptitious experiment that was not explicitly health related. Our results suggest that perceptions about the controllability of mortality risk may be an important factor in people's health-related decisions. Thus, techniques for adjusting perceptions about mortality risk could be important tools for use in health interventions. More importantly, tackling those sources of mortality that people perceive to be uncontrollable could have a dual purpose: making neighbourhoods and workplaces safer would have the primary benefit of reducing uncontrollable mortality risk, which could lead to a secondary benefit from improved health behaviours.

  1. Geographic distribution of dementia mortality: elevated mortality rates for black and white Americans by place of birth. (United States)

    Glymour, M Maria; Kosheleva, Anna; Wadley, Virginia G; Weiss, Christopher; Manly, Jennifer J


    We hypothesized that patterns of elevated stroke mortality among those born in the United States Stroke Belt (SB) states also prevailed for mortality related to all-cause dementia or Alzheimer Disease. Cause-specific mortality (contributing cause of death, including underlying cause cases) rates in 2000 for United States-born African Americans and whites aged 65 to 89 years were calculated by linking national mortality records with population data based on race, sex, age, and birth state or state of residence in 2000. Birth in a SB state (NC, SC, GA, TN, AR, MS, or AL) was cross-classified against SB residence at the 2000 Census. Compared with those who were not born in the SB, odds of all-cause dementia mortality were significantly elevated by 29% for African Americans and 19% for whites born in the SB. These patterns prevailed among individuals who no longer lived in the SB at death. Patterns were similar for Alzheimer Disease-related mortality. Some non-SB states were also associated with significant elevations in dementia-related mortality. Dementia mortality rates follow geographic patterns similar to stroke mortality, with elevated rates among those born in the SB. This suggests important roles for geographically patterned childhood exposures in establishing cognitive reserve.

    Engels, H.; Holmstock, L.; Mieghem, E. Van; Swaen, G.M.; Wambersie, A.


    To investigate long term health effects of chronic exposure to low doses of ionising radiation, the Nuclear Research Center (SCK.CEN) in Mol set up a retrospective cohort study in 5 nuclear facilities in Belgium (SCK.CEN, Belgonucleaire, Belgoprocess, 2 Electrabel nuclear power plants). Cancer mortality among nuclear workers is studied in relation to occupational exposure to ionising radiation. This study is part of the 'International Collaborative Study on Cancer Risk among Radiation Workers', coordinated by the International Agency for Research on Cancer (IARC/WHO), pooling data of 14 countries. During the period 1953-1994, all workers registered in one of the participating facilities were included in the study (n=7361). Data have been collected from different information sources: personnel registries (identification, occupational history), dosimetry records (e.g. annual effective dose), National Population Registry and local authorities (vital status). National Institute of Statistics (causes of death from the death certificates), National Radiation Registry/Ministry of Labour (transfer doses), questionnaires (e.g. smoking habits). Retrospective collection of data and privacy protection regulations specific to Belgium hampered the conduct of this study, causing labour intensive and time consuming procedures. Written informed consent of next-of-kin is required to obtain information from the death certificates. Before 1969 only family reported causes of death are available. Despite the above mentioned constraints, first results of Standardised Mortality Ratio (SMR) calculations are now available for SCK.CEN workers for the period 1969-1994 (n=3270, vital status ascertainment: 95%, underlying cause of death ascertainment: 80%). Available SMR's can be summarised as follows: male workers, no measurable dose (n=785): SMR all causes=75% (95%CI: 61-91), SMR all tumours=64% (95%CI: 42-93), 2 leukemia deaths were observed, whereas 1 is expected, male workers, measurable

  3. [Socioeconomic inequalities and infant mortality in Bolivia]. (United States)

    Maydana, Edgar; Serral, Gemma; Borrell, Carme


    To evaluate socioeconomic inequalities and its relation to infant mortality in Bolivia's municipalities in 2001. An ecological study based on data from the 2001 National Census on Population and Housing (Censo Nacional de Población y Vivienda) covering the 327 municipalities in Bolivia's nine departments. The dependent variable was the infant mortality rate (IMR); the independent variables were indirect socioeconomic indicators (the percentage of illiterates older than 15 years of age, and the building materials and sanitation features of the houses). The geographic distribution of each indicator was determined and the associations between IMR and each socioeconomic indicator were calculate using Spearman's rank correlation coefficient and adjusted with Poisson regression models. The resulting IMR for Bolivia in 2001 was 67 per 1000 live births. Rates ranged from <0.1 per 1000 live births in the Magdalena municipality, Beni department, to 170.0 per 1000 live births in the Caripuyo municipality, Potosí department. The mean rate of illiteracy per municipality was 17.5%; the mean percentage of houses without running water was 90.4%, and for those lacking sanitation services, 67.6%. The IMR was inversely associated with all of the socioeconomic indicators studied. The highest relative risk was found in housing without sanitation services. Multifactorial models adjusted for illiteracy showed that the following indicators were still strongly associated with the IMR: no sanitation services (Relative risk (RR)=1.54; 95% Confidence Interval (95%CI)=1.38-1.66); adobe, stone, or mud walls (RR=1.54; 95%CI: 1.43-1.67); and, corrugated metal, straw, or palm branch roof (RR=1.34; 95%CI: 1.26-1.43). A significant association was found between poor socioeconomic status and high IMR in Bolivia's municipalities in 2001. The municipalities in the country's central and southeastern areas had lower socioeconomic status and higher IMR. The lack of education, absence of basic sanitation

  4. Mortality of German travellers on passenger vessels. (United States)

    Oldenburg, Marcus; Herzog, Jan; Püschel, Klaus; Harth, Volker


    In the past two decades, more and more Germans decided to spend their holidays on a passenger vessel. This study examined the frequencies and causes of deaths of German travellers aboard passenger vessels of all flags. The shipboard deaths of all German travellers within the time period from 1998 to 2008 were counted using the German civil central register in Berlin. The available documentation in this register provides information on frequencies, circumstances and causes of deaths on ships. In the above-mentioned period of time, the total cohort of German travellers on cruise ships is estimated to be 5.97 million persons. During the 11-year examination period, 135 shipboard deaths of German passengers [102 males (75.6%) and 33 females (24.4%)] were recorded. Out of these travellers, 110 died on cruise ships. When considering only the passengers on cruise ships (without those on ferries) an average crude mortality rate of 1.8 per 100,000 German passengers was calculated. The crude mortality rate of shipboard death for males and females was 2.5 and 0.8 per 100,000 German passengers with a mean age of 71.2 years [standard deviation (SD) 16.0 years] and 73.3 years (SD 16.0 years), respectively. Significantly, more deceased travellers older than 70 years were observed on traditional cruise ships and resort vessels than on passenger ferries (P = 0.001). The causes of death were documented in 85 cases (63.0%). Out of these documented deaths, 82 (96.5%) cases were regarded to be natural causes (particularly circulatory diseases) and 3 (3.5%) as unnatural causes (twice drowning and once an accidental fall). In spite of the large proportion of unknown causes of death, this study argues for a high significance of internal causes of deaths among German passengers. Thus, ship's doctors-particularly those on traditional cruise ships-should be well experienced in internal and geriatric medicines. © The Author 2016.

  5. Anesthesia-related mortality in pediatric patients: a systematic review. (United States)

    Gonzalez, Leopoldo Palheta; Pignaton, Wangles; Kusano, Priscila Sayuri; Módolo, Norma Sueli Pinheiro; Braz, José Reinaldo Cerqueira; Braz, Leandro Gobbo


    This systematic review of the Brazilian and worldwide literature aimed to evaluate the incidence and causes of perioperative and anesthesia-related mortality in pediatric patients. Studies were identified by searching EMBASE (1951-2011), PubMed (1966-2011), LILACS (1986-2011), and SciElo (1995-2011). Each paper was revised to identify the author(s), the data source, the time period, the number of patients, the time of death, and the perioperative and anesthesia-related mortality rates. Twenty trials were assessed. Studies from Brazil and developed countries worldwide documented similar total anesthesia-related mortality rates (anesthesia-related mortality rates in the past decade. Higher anesthesia-related mortality rates (2.4-3.3 per 10,000 anesthetics) were found in studies from developing countries over the same time period. Interestingly, pediatric perioperative mortality rates have increased over the past decade, and the rates are higher in Brazil (9.8 per 10,000 anesthetics) and other developing countries (10.7-15.9 per 10,000 anesthetics) compared with developed countries (0.41-6.8 per 10,000 anesthetics), with the exception of Australia (13.4 per 10,000 anesthetics). The major risk factors are being newborn or less than 1 year old, ASA III or worse physical status, and undergoing emergency surgery, general anesthesia, or cardiac surgery. The main causes of mortality were problems with airway management and cardiocirculatory events. Our systematic review of the literature shows that the pediatric anesthesia-related mortality rates in Brazil and in developed countries are similar, whereas the pediatric perioperative mortality rates are higher in Brazil compared with developed countries. Most cases of anesthesia-related mortality are associated with airway and cardiocirculatory events. The data regarding anesthesia-related and perioperative mortality rates may be useful in developing prevention strategies.

  7. Countries with women inequalities have higher stroke mortality. (United States)

    Kim, Young Dae; Jung, Yo Han; Caso, Valeria; Bushnell, Cheryl D; Saposnik, Gustavo


    Background Stroke outcomes can differ by women's legal or socioeconomic status. Aim We investigated whether differences in women's rights or gender inequalities were associated with stroke mortality at the country-level. Methods We used age-standardized stroke mortality data from 2008 obtained from the World Health Organization. We compared female-to-male stroke mortality ratio and stroke mortality rates in women and men between countries according to 50 indices of women's rights from Women, Business and the Law 2016 and Gender Inequality Index from the Human Development Report by the United Nations Development Programme. We also compared stroke mortality rate and income at the country-level. Results In our study, 176 countries with data available on stroke mortality rate in 2008 and indices of women's rights were included. There were 46 (26.1%) countries where stroke mortality in women was higher than stroke mortality in men. Among them, 29 (63%) countries were located in Sub-Saharan African region. After adjusting by country income level, higher female-to-male stroke mortality ratio was associated with 14 indices of women's rights, including differences in getting a job or opening a bank account, existence of domestic violence legislation, and inequalities in ownership right to property. Moreover, there was a higher female-to-male stroke mortality ratio among countries with higher Gender Inequality Index (r = 0.397, p Gender Inequality Index was more likely to be associated with stroke mortality rate in women than that in men (p gender inequality status is associated with women's stroke outcomes.

  8. Variability in the measurement of hospital-wide mortality rates. (United States)

    Shahian, David M; Wolf, Robert E; Iezzoni, Lisa I; Kirle, Leslie; Normand, Sharon-Lise T


    Several countries use hospital-wide mortality rates to evaluate the quality of hospital care, although the usefulness of this metric has been questioned. Massachusetts policymakers recently requested an assessment of methods to calculate this aggregate mortality metric for use as a measure of hospital quality. The Massachusetts Division of Health Care Finance and Policy provided four vendors with identical information on 2,528,624 discharges from Massachusetts acute care hospitals from October 1, 2004, through September 30, 2007. Vendors applied their risk-adjustment algorithms and provided predicted probabilities of in-hospital death for each discharge and for hospital-level observed and expected mortality rates. We compared the numbers and characteristics of discharges and hospitals included by each of the four methods. We also compared hospitals' standardized mortality ratios and classification of hospitals with mortality rates that were higher or lower than expected, according to each method. The proportions of discharges that were included by each method ranged from 28% to 95%, and the severity of patients' diagnoses varied widely. Because of their discharge-selection criteria, two methods calculated in-hospital mortality rates (4.0% and 5.9%) that were twice the state average (2.1%). Pairwise associations (Pearson correlation coefficients) of discharge-level predicted mortality probabilities ranged from 0.46 to 0.70. Hospital-performance categorizations varied substantially and were sometimes completely discordant. In 2006, a total of 12 of 28 hospitals that had higher-than-expected hospital-wide mortality when classified by one method had lower-than-expected mortality when classified by one or more of the other methods. Four common methods for calculating hospital-wide mortality produced substantially different results. This may have resulted from a lack of standardized national eligibility and exclusion criteria, different statistical methods, or

  9. Female circumcision and child mortality in urban Somalia. (United States)

    Mohamud, O A


    In Somalia, a demographer analyzed urban data obtained from the Family Health Survey to examine the effect female circumcision has on child mortality and the mechanism of that effect. Girls undergo female circumcision between 5-12 years old in Somalia. Since sunni circumcision (removal of the clitoral prepuce and tip of the clitoris) and clitoridectomy (removal of the entire clitoris) did not affect child mortality, he used them as the reference group. Infibulation (entire removal of the clitoris and of the labia minora and majora with the remains of the labia majora being sewn together allowing only a small opening for passage of urine) did affect child mortality. Female children who underwent infibulation and whose mothers most likely also underwent infibulation experienced higher mortality (13-72%) than those from other circumcised mothers. Female mortality exceeded male mortality indicating possible son preference. Mothers with clitoridectomy or infibulation had significantly higher infant mortality than those with sunni circumcision with the strongest effects during the neonatal period (95% and 42% higher mortality, respectively; p=.01). The effect of female circumcision on child mortality decreased with increased child's age. This higher than expected mortality among women with clitoridectomy may have been because women with infibulation had more stillbirths which were not counted as births. The exposed vagina of clitoridectomized women is more likely to be infected resulting in high risk of stillbirths and premature births than the closed vagina of infibulated women. The researcher suggested that the policies promoting education and consciousness raising may eventually eradicate female circumcision. This longterm campaign should use mass media, senior women of high status, and respected religious leaders. Legislation prohibiting this practice would only drive it underground under unsanitary conditions. Demographers should no longer ignore female circumcision

  10. Neonatal mortality in Bavaria during 1972 to 1990

    International Nuclear Information System (INIS)

    Irl, C.; Schoetzau, A.; Steinhilber, B.; Grosche, B.; Jahraus, H.; Santen, E. van.


    The present report deals with the neonatal mortality in Bavaria during 1972 to 1990, the last period of which coincided with the reactor accident of Chernobyl. The question arose whether there was an increase in neonatal mortality in the more heavily exposed regions of Bavaria as an aftermath to this accident. The results of the study may be summarized as follows: During the period of interest there was a decrease in neonatal mortality in the Federal Republic of Germany (former Federal Lands) and in Bavaria from 22 permille (1972) to less than one third of this value. With a mortality rate of 6.2 permille . Bavaria was below the Federal average of 7.1 permille . in 1990. This decrease is mainly due to a decline in early mortality. Mortality during the first year of life was higher in male than in female infants. 57% of the deceased infants were male, 43% female. The spatial distribution of neonatal mortality in Bavaria showed large regional differences. Following standardisation of the raw data the lowest value of a rural district averaged over the 19 years covered was 7.1 permille , the highest being 21 permille . When the infant mortality rates of regions in Southern Bavaria which were defined as being more heavily exposed to radiation after the Chernobyl accident (> 30 kBq/m 2 Cs- 137), no statistically significant difference was detected for any of the year between 1980 to 1990. Similarly, no statistical correlation could be found between neonatal mortality and proximity of the residence to one of the five sites of nuclear reactors in Bavaria. Out of the further environmental variables included in the study the factors 'urbanity' and 'unemployment' showed a statistical correlation with the infant mortality rate. Over the entire study period (1972 to 1990) the infant mortality rate was found to be significantly increased in towns (constituting administrative districts of their own) compared to rural districts.

    Rezvanfar, M.R.; Dalvandy, M.; Emami, A.R.; Rafiee, M.; Eshratee, B.


    To analyze the relation between serum glucose concentration and hospital outcome across the critically ill patients. A single-centre, retrospective study was performed at surgical and medical intensive care unit. Admission glucose, mean morning glucose, mean glucose, maximal glucose and time-averaged glucose levels were calculated for each patient. The time-averaged hyperglycemia was defined as the area under the curve above the upper limit of normal, divided by the total length of stay. Of 300 patients with a median stay of 16 days, the mortality rate was 32%. Mean fasting glucose was 121 mg/dl in survivors versus 160 mg/dl in non survivors (P=0.001). Mean admission glucose was 127 mg/dl in survivors versus 142 mg/dl in non survivors (0.03). Median time-averaged hyperglycemia was 4 mg/dl in survivors versus 17.5 mg/dl in non survivors (P < 0.006). The area under the receiver operator characteristic (ROC) curve was 0.59 for time-averaged glucose and 0.73 for mean fasting glucose. Whereas time-averaged hyperglycemia is a useful assessment for glucose control in critically ill patients, it has no priority to admission glucose and mean fasting glucose for outcome prediction.

  12. Global justice, poverty and maternal mortality

    Directory of Open Access Journals (Sweden)

    Flor de María Cáceres M


    Full Text Available Global justice is currently situated in an ambiance of tension and debate, facing a series of statements attempting to explain relationships among countries, based on the background of agreements already accomplished by supranational agencies. This network of relationships, not always fair nor equitable, has resulted in an increased accumulation of wealth in just a few hands and poverty in a growing number of people in poor countries and geographic areas with restrictions to access both to resources and to technological and scientific advances. Poverty, exclusion and inequalities limit all together the opportunities for development in these communities, with the outcome of serious consequences such as the deterioration in basic indicators of development. Maternal mortality rate (mm is considered a sentinel indicator since it belongs in most cases to premature deaths which would be avoidable through proper measures in education, health promotion and timely access to quality health services. The purpose of this essay is to defend the thesis that the lack of global justice has limited the scope of the goals related to poverty and mm reduction

    Javad Salimi

    Full Text Available CONTEXT AND OBJECTIVE: The presence of scapular fracture is believed to be associated with high rates of other injuries and accompanying morbidities. The aim was to study injury patterns and their overall outcomes in patients with scapula fractures. DESIGN AND SETTING: Cross-sectional study of trauma patients treated at six general hospitals in Tehran. METHODS: One-year trauma records were obtained from six general hospitals Among these, forty-one had sustained a scapular fracture and were included in this study. RESULTS: Scapular fracture occurred predominantly among 20 to 50-year-old patients (78%. Road traffic accidents (RTAs were the main cause of injury (73.2%; 30/41. Pedestrians accounted for 46.7% (14/30 of the injuries due to RTAs. Falls were the next most common cause, accounting for seven cases (17.1%. Body fractures were the most common type of scapular fractures (80%. Eighteen patients (43.9% had isolated scapular fractures. Limb fracture was the most common associated injury, detected in 18 cases (43.9%. Three patients (7.3% had severe injuries (injury severity score, ISS > 16 which resulted in one death (2.4%. The majority of the patients were treated conservatively (87.8%. CONCLUSIONS: Patients with scapula fractures have more severe underlying chest injuries and clavicle fractures. However, this did not correlate with higher rates of injury severity score, intensive care unit admission or mortality.

  14. [Glycemic targets and cardiovascular morbi-mortality]. (United States)

    Bordier, Lyse; Bauduceau, Bernard


    The 2008-year was full of learning experience and suspense in diabetologia. The past studies, UKPDS in type 2 diabetic patients and DCCT in type 1 diabetic patients have shown that intensive treatment during a short period did reduce the incidence of microvascular events and in the long term, the incidence of macrovascular events linked to diabetes. The conclusions of recent studies quote, from ACCORD, an increased mortality in the type 2 diabetic patients using intensive therapy, from ADVANCE, a reduction of microvascular complications and from VADT, no effect. The analysis of studies published since 2008 brings lessons for the clinical practice: presence of glycemic memory, absence of tensional memory, usefulness of control of every cardiovascular risk factors, need of early treatment of diabetes. Moreover, to define HbA1c objective, age, duration of diabetes, presence of cardiovascular risk factors, former HbA1c level and potential undesirable effects, such hypoglycaemia, must be considered. The management of type 2 diabetic patients requires an early, not to quick intensive treatment, which avoids hypoglycaemia and is combined with a strict control of cardiovascular risk factors. So, the recent position statement of the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) consideres needs and preferences of each patient and individualizes glycemic targets and treatments.

  2. Age dependent mortality in the pilocarpine model of status epilepticus (United States)

    Blair, Robert E.; Deshpande, Laxmikant S.; Holbert, William H.; Churn, Severn B.; DeLorenzo, Robert J.


    Status epilepticus (SE) is an acute neurological emergency associated with significant morbidity and mortality. Age has been shown to be a critical factor in determining outcome after SE. Understanding the causes of this increased mortality with aging by developing an animal model to study this condition would play a major role in studying mechanisms to limit the mortality due to SE. Here we employed pilocarpine to induce SE in rats aged between 5 to 28 weeks. Similar to clinical studies in man, we observed that age was a significant predictor of mortality following SE. While no deaths were observed in 5-week old animals, mortality due to SE increased progressively with age and reached 90% in 28-week old animals. There was no correlation between the age of animals and severity of SE. With increasing age mortality occurred earlier after the onset of SE. These results indicate that pilocarpine-induced SE in the rat provides a useful model to study age-dependent SE-induced mortality and indicates the importance of using animal models to elucidate the mechanisms contributing to SE-induced mortality and the development of novel therapeutic interventions to prevent SE-induced death.

  3. Autumn Weather and Winter Increase in Cerebrovascular Disease Mortality

    LENUS (Irish Health Repository)

    McDonagh, R


    Mortality from cerebrovascular disease increases in winter but the cause is unclear. Ireland’s oceanic climate means that it infrequently experiences extremes of weather. We examined how weather patterns relate to stroke mortality in Ireland. Seasonal data for Sunshine (% of average), Rainfall (% of average) and Temperature (degrees Celsius above average) were collected for autumn (September-November) and winter (December-February) using official Irish Meteorological Office data. National cerebrovascular mortality data was obtained from Quarterly Vital Statistics. Excess winter deaths were calculated by subtracting (nadir) 3rd quarter mortality data from subsequent 1st quarter data. Data for 12 years were analysed, 2002-2014. Mean winter mortality excess was 24.7%. Winter mortality correlated with temperature (r=.60, p=0.04). Rise in winter mortality correlated strongly with the weather in the preceding autumn (Rainfall: r=-0.19 p=0.53, Temperature: r=-0.60, p=0.03, Sunshine, r=0.58, p=0.04). Winter cerebrovascular disease mortality appears higher following cool, sunny autum

    The prevalence of thyroid cancer has increased very rapidly in Korea. However, there is no published report focusing on thyroid cancer mortality in Korea. In this study, we aimed to evaluate standardized thyroid cancer mortality using data from Statistics Korea (the Statistical Office of Korea). Population and mortality data from 1985 to 2010 were obtained from Statistics Korea. Age-standardized rates of thyroid cancer mortality were calculated according to the standard population of Korea, as well as World Health Organization (WHO) standard population and International Cancer Survival Standard (ICSS) population weights. The crude thyroid cancer mortality rate increased from 0.1 to 0.7 per 100,000 between 1985 and 2010. The pattern was the same for both sexes. The age-standardized mortality rate (ASMR) for thyroid cancer for Korean resident registration population increased from 0.19 to 0.67 between 1985 and 2000. However, it decreased slightly, from 0.67 to 0.55, between 2000 and 2010. When mortality was adjusted using the WHO standard population and ICSS population weights, the ASMR similarly increased until 2000, and then decreased between 2000 and 2010. Thyroid cancer mortality increased until 2000 in Korea. It started to decrease from 2000.

  12. Low infant mortality among Palestine refugees despite the odds (United States)

    Khader, Ali; Sabatinelli, Guido


    Abstract Objective To present data from a 2008 infant mortality survey conducted in Jordan, Lebanon, the Syrian Arab Republic, the Gaza Strip and the West Bank and analyse infant mortality trends among Palestine refugees in 1995–2005. Methods Following the preceding birth technique, mothers who were registering a new birth were asked if the preceding child was alive or dead, the day the child was born and the date of birth of the neonate whose birth was being registered. From this information, neonatal, infant and early child mortality rates were estimated. The age at death for early child mortality was determined by the mean interval between successive births and the mean age of neonates at registration. Findings In 2005–2006, infant mortality among Palestine refugees ranged from 28 deaths per 100 000 live births in the Syrian Arab Republic to 19 in Lebanon. Thus, infant mortality in Palestine refugees is among the lowest in the Near East. However, infant mortality has stopped decreasing in recent years, although it remains at a level compatible with the attainment of Millennium Development Goal 4. Conclusion Largely owing to the primary health care provided by the United Nations Relief and Works Agency (UNRWA) for Palestine Refugees in the Near East and other entities, infant mortality among Palestine refugees had consistently decreased. However, it is no longer dropping. Measures to address the most likely reasons – early marriage and childbearing, poor socioeconomic conditions and limited access to good perinatal care – are needed.

  19. Beverage-Specific Alcohol Sale and Cardiovascular Mortality in Russia

    Directory of Open Access Journals (Sweden)

    Y. E. Razvodovsky


    Full Text Available Objective. Recent research evidence suggests that the consumption of different types of alcoholic beverage may have a differential effect on cardiovascular diseases (CVD mortality rates. The aim of this study was to examine the relation between the consumption of different beverage types and CVD mortality rates in Russia across the later-Soviet and post-Soviet periods. Method. Age-standardized male and female CVD mortality data for the period 1970–2005 and data on beverage-specific alcohol sales were obtained Russian State Statistical Committee (Rosstat. Time-series analytical modeling techniques (ARIMA were used to examine the relation between the sales of different alcoholic beverages and CVD mortality rates. Results. Vodka consumption as measured by sales was significantly associated with both male and female CVD mortality rates: a 1 liter increase in vodka sales would result in a 5.3% increase in the male CVD mortality rate and a 3.7% increase in the female rate. The consumption of beer and wine were not associated with CVD mortality rates. Conclusions. The findings from this study suggest that public health efforts should focus on both reducing overall consumption and changing beverage preference away from distilled spirits in order to reduce cardiovascular mortality rates in Russia.

    Lara A. Roman; John J. Battles; Joe R. McBride


    Realizing the benefits of tree planting programs depends on tree survival. Projections of urban forest ecosystem services and cost-benefit analyses are sensitive to assumptions about tree mortality rates. Long-term mortality data are needed to improve the accuracy of these models and optimize the public investment in tree planting. With more accurate population...

  6. Educational inequalities in tuberculosis mortality in sixteen European populations (United States)

    Álvarez, J. L.; Kunst, A. E.; Leinsalu, M.; Bopp, M.; Strand, B. H.; Menvielle, Gwenn; Lundberg, O.; Martikainen, P.; Deboosere, P.; Kalediene, R.; Artnik, B.; Mackenbach, J. P.; Richardus, J. H.


    Objective We aim to describe the magnitude of socioeconomic inequalities in tuberculosis (TB) mortality by level of education in male, female, urban, and rural populations in several European countries. Design Data were obtained from the Eurothine project covering 16 populations between 1990 and 2003. Age- and sex-standardized mortality rates, the Relative Index of Inequality, and the slope index of inequality were used to assess educational inequalities. Results The number of TB deaths reported was 8530, with a death rate of 3 per 100 000 per year, of which 73% were males. Educational inequalities in TB mortality were present in all European populations. Inequalities in TB mortality were larger than in total mortality. Relative and absolute inequalities were large in Eastern Europe, and Baltic countries but relatively small in Southern countries and in Norway, Finland, and Sweden. Mortality inequalities were observed among both men and women, and in both rural and urban populations. Conclusions Socioeconomic inequalities in TB mortality exist in all European countries. Firm political commitment is required to reduce inequalities in the social determinants of TB incidence. Targeted public health measures are called for to improve vulnerable groups’ access to treatment and thereby reduce TB mortality. PMID:22008757
