    We performed a multicenter prospective observational cohort study (Epidémiologie et Pronostic de l'Insuffisance Cardiaque Aiguë en Lorraine, Epidemiology and Prognosis of Acute Heart Failure in Lorraine [EPICAL2]) to evaluate the effectiveness on mortality of a community-based multidisciplinary disease management programme (DMP) for heart failure (HF) patients.Between October 2011 and October 2012, 1816 patients, who were hospitalized for acute HF or who developed acute HF during a hospitalization, were included from 21 hospitals in a northeast region of France. At hospital admission, their mean age was 77.3 (standard deviation [SD] 11.6) years and mean left ventricular ejection fraction was 45.0 (SD 16.0)%. A subset of patients were enrolled in a multidimensional DMP for HF (n = 312, 17.2%), based on structured patient education, home monitoring visits by HF-trained nurses, and automatic alerts triggered by significant clinical and biological changes to the patient. The DMP involved general practitioners, nurses, and cardiologists collaborating via an individual web-based medical electronic record. The outcome was all-cause mortality from the 3rd to the 12th month after discharge. During the follow-up, a total of 377 (20.8%) patients died: 321 (21.3%) in the control group and 56 (17.9%) in the DMP group. In a propensity score analysis, DMP was associated with lower 1-year all-cause mortality (hazard ratio 0.65, 95% CI 0.46-0.92). Instrumental variable analysis gave similar results (hazard ratio 0.56, 0.27-1.16).In a real world setting, a multidimensional DMP for HF with structured patient education, home nurse monitoring, and appropriate physician alerts may improve survival when implemented after discharge from hospitalization due to worsening HF.

    This study aimed to construct a scoring system developed exclusively from the preoperative data that predicts 1-year postoperative mortality in patients with solid cancers. A total of 20,632 patients who had a curative resection for solid-organ cancers between 2007 and 2012 at Chang Gung Memorial Hospital Linkou Medical Center were included in the derivation cohort. Multivariate logistic regression analysis was performed to develop a risk model that predicts 1-year postoperative mortality. Patients were then stratified into four risk groups (low-, intermediate-, high-, and very high-risk) according to the total score (0–43) form mortality risk analysis. An independent cohort of 16,656 patients who underwent curative cancer surgeries at three other hospitals during the same study period (validation cohort) was enrolled to verify the risk model. Age, gender, cancer site, history of previous cancer, tumor stage, Charlson comorbidity index, American Society of Anesthesiologist score, admission type, and Eastern Cooperative Oncology Group performance status were independently predictive of 1-year postoperative mortality. The 1-year postoperative mortality rates were 0.5%, 3.8%, 14.6%, and 33.8%, respectively, among the four risk groups in the derivation cohort (c-statistic, 0.80), compared with 0.9%, 4.2%, 14.6%, and 32.6%, respectively, in the validation cohort (c-statistic, 0.78). The risk stratification model also demonstrated good discrimination of long-term survival outcome of the four-tier risk groups (P < 0.01 for both cohorts). The risk stratification model not only predicts 1-year postoperative mortality but also differentiates long-term survival outcome between the risk groups. PMID:26311149

    Background Renal impairment is a common comorbidity and the strongest risk factor for poor prognosis in acute decompensated heart failure (ADHF). In clinical practice, renal function is labile during episodes of ADHF, and often worsens after discharge. The significance of worsening of renal function (WRF) after discharge has not been investigated as extensively as baseline renal function at admission or WRF during hospitalization. Methods and Results Among 611 consecutive patients with ADHF emergently admitted to our hospital, 233 patients with 3 measurements of serum creatinine (SCr) level measurements (on admission, at discharge, and 1 year after discharge) were included in the present study. Patients were divided into 2 groups according to the presence or absence of WRF at 1 year after discharge (1y‐WRF), defined as an absolute increase in SCr >0.3 mg/dL (>26.5 μmol/L) plus a ≥25% increase in SCr at 1 year after discharge compared to the SCr value at discharge. All‐cause and cardiovascular mortality were assessed as adverse outcomes. During a mean follow‐up of 35.4 months, 1y‐WRF occurred in 48 of 233 patients. There were 66 deaths from all causes. All‐cause and cardiovascular mortality were significantly higher in patients with 1y‐WRF (log‐rank P<0.0001 and P<0.0001, respectively) according to Kaplan–Meier analysis. In a multivariate Cox proportional hazards model, 1y‐WRF was a strong and independent predictor of all‐cause and cardiovascular mortality. Hemoglobin and B‐type natriuretic peptide at discharge, as well as left ventricular ejection fraction <50%, were independent predictors of 1y‐WRF. Conclusions In patients with ADHF, 1y‐WRF is a strong predictor of all‐cause and cardiovascular mortality. PMID:25370599

    Background Few risk scores are available for predicting mortality in chronic kidney disease (CKD) patients undergoing predialysis nephrology care. Here, we developed a risk score using predialysis nephrology practice data to predict 1-year mortality following the initiation of haemodialysis (HD) for CKD patients. Methods This was a multicenter cohort study involving CKD patients who started HD between April 2006 and March 2011 at 21 institutions with nephrology care services. Patients who had not received predialysis nephrology care at an estimated glomerular filtration rate (eGFR) of approximately 10 mL/min per 1.73 m2 were excluded. Twenty-nine candidate predictors were selected, and the final model for 1-year mortality was developed via multivariate logistic regression and was internally validated by a bootstrapping technique. Results A total of 688 patients were enrolled, and 62 (9.0%) patients died within one year of HD initiation. The following variables were retained in the final model: eGFR, serum albumin, calcium, Charlson Comorbidity Index excluding diabetes and renal disease (modified CCI), performance status (PS), and usage of erythropoiesis-stimulating agent (ESA). Their β-coefficients were transformed into integer scores: three points were assigned to modified CCI≥3 and PS 3–4; two to calcium>8.5 mg/dL, modified CCI 1–2, and no use of ESA; and one to albumin<3.5 g/dL, eGFR>7 mL/min per 1.73 m2, and PS 1–2. Predicted 1-year mortality risk was 2.5% (score 0–4), 5.5% (score 5–6), 15.2% (score 7–8), and 28.9% (score 9–12). The area under the receiver operating characteristic curve was 0.83 (95% confidence interval, 0.79–0.89). Conclusions We developed a simple 6-item risk score predicting 1-year mortality after the initiation of HD that might help nephrologists make a shared decision with patients and families regarding the initiation of HD.

    Aim MULTIPRAC was designed to provide insights into the use and outcomes associated with prehospital initiation of antiplatelet therapy with either prasugrel or clopidogrel in the context of primary percutaneous coronary intervention. After a previous report on efficacy and safety outcomes during hospitalization, we report here the 1-year follow-up data, including cardiovascular (CV) mortality. Methods and results MULTIPRAC is a multinational, prospective registry of patients with ST-elevation myocardial infarction (STEMI) from 25 hospitals in nine countries, all of which had an established practice of prehospital start of dual antiplatelet therapy in place. The key outcome was CV death at 1 year. Among 2,036 patients followed-up through 1 year, 49 died (2.4%), 10 during the initial hospitalization and 39 within 1 year after hospital discharge. The primary analysis was based on the P2Y12-inhibitor, used from prehospital loading dose through hospital discharge. Prasugrel (n=824) was more commonly used than clopidogrel (n=425). The observed 1-year rates for CV death were 0.5% with prasugrel and 2.6% with clopidogrel. After adjustment for differences in baseline characteristics, treatment with prasugrel was associated with a significantly lower risk of CV death than treatment with clopidogrel (odds ratio 0.248; 95% confidence interval 0.06–0.89). Conclusion In STEMI patients from routine practice undergoing primary angioplasty, who were able to start oral antiplatelet therapy prehospital, treatment with prasugrel as compared to clopidogrel was associated with a lower risk of CV death at 1-year follow-up.

    Backgrounds and Aims The presence and progression of vascular calcification have been demonstrated as important risk factors for mortality in dialysis patients. However, since the majority of subjects included in most previous studies were hemodialysis patients, limited information was available in peritoneal dialysis (PD) patients. Therefore, the aim of this study was to investigate the prevalence of aortic arch calcification (AoAC) and prognostic value of AoAC progression in PD patients. Methods We prospectively determined AoAC by chest X-ray at PD start and after 12 months, and evaluated the impact of AoAC progression on mortality in 415 incident PD patients. Results Of 415 patients, 169 patients (40.7%) had AoAC at baseline with a mean of 18.1±11.2%. The presence of baseline AoAC was an independent predictor of all-cause [Hazard ratio (HR): 2.181, 95% confidence interval (CI): 1.336–3.561, P = 0.002] and cardiovascular mortality (HR: 3.582, 95% CI: 1.577–8.132, P = 0.002). Among 363 patients with follow-up chest X-rays at 12 months after PD start, the proportion of patients with AoAC progression was significantly higher in patients with baseline AoAC (64.2 vs. 5.3%, P<0.001). Moreover, all-cause and cardiovascular death rates were significantly higher in the progression groups than in the non-progression group (P<0.001). Multivariate Cox analysis revealed that AoAC progression was an independent predictor for all-cause (HR: 2.625, 95% CI: 1.150–5.991, P = 0.022) and cardiovascular mortality (HR: 4.008, 95% CI: 1.079–14.890, P = 0.038) in patients with AoAC at baseline. Conclusions The presence and progression of AoAC assessed by chest X-ray were independently associated with unfavorable outcomes in incident PD patients. Regular follow-up by chest X-ray could be a simple and useful method to stratify mortality risk in these patients. PMID:23144974

    The scope of this study is to perform spatial analysis of integrated environmental and health indicators related to the factors affecting mortality due to diarrhea in children under 1 year of age in Brazilian regions in 2010. Seven environmental indicators, compiled from the IBGE System for Automatic Recovery of the Population Census 2010 database, were formulated. The data with respect to deaths due to diarrhea in children under 1 year of age and live births were obtained from the databases of the Mortality Information Systems and the Live Births Information System of the IT Department of the Unified Health System. The microregions located in the North and Northeast regions revealed 5 and 4 times the rate of mortality in 2009, respectively, due to diarrhea in children under 1 year of age than the Southern Region. Children under 1 year of age living in the microregions located in the North and Northeast are more exposed to risk of death from diarrhea, since the worst figures for the environmental indicators related to poverty and sanitation are concentrated in these locations. In this sense, social, economic, environmental, cultural and health public policies should be based on the principle of equity to address the different local needs of each region.

    The aim of this study is to evaluate the factors associated to 1-year mortality in clinically amyopathic dermatomyositis (CADM) patients with acute interstitial lung disease (ILD). A single center of 37 cases of Chinese patients with CADM was reviewed retrospectively in Renji hospital. All CADM patients were diagnosed with ILD; there were 24 cases of acute interstitial pneumonia (AIP) and 13 cases of acute exacerbation of non-acute interstitial pneumonia non-AIP. The clinical features, including blood tests, chest high-resolution computed tomography (HRCT) score, and lung function, were analyzed, respectively. Neutrophil lymphocyte ratio (NLR), serum ferritin level, serum lactate dehydrogenase (LDH) level, and HRCT score were statistically significant factors on univariate analysis. Multivariate analysis revealed that the overall HRCT score (HR 1.134, 95 % confidence interval 1.009-1.275, P = 0.017) and serum ferritin level (HR 1.001, 95 % confidence interval 1.002-1.007, P = 0.010) were independently significant factors of 1-year mortality. C statistic value of HRCT score (c statistic value 0.867, P < 0.0001) and serum ferritin level (c statistic value 0.808, P = 0.002) were statistically significant in the classification of non-survivors. Patients with calcineurin inhibitor presented a better outcome than those without calcineurin inhibitor (log-rank test, P = 0.006). HRCT score and serum ferritin level are factors associated to the 1-year mortality of acute ILD in CADM patients. Calcineurin inhibitor might improve the outcome of CADM patients with acute ILD.

    Background Few studies have reported CD4%- and age-stratified rates of WHO Stage 3 (WHO3) events, WHO Stage 4 (WHO4) events, tuberculosis (TB), and mortality in HIV-infected infants before initiation of antiretroviral therapy (ART). Methods HIV-infected children enrolled before 1 year of age in the International Epidemiologic Databases to Evaluate AIDS (IeDEA) East Africa region (10/01/2002-11/30/2008) were included. We estimated incidence rates of earliest clinical event (WHO3, WHO4, and TB), prior to ART initiation per local guidelines, stratified by current age (< or ≥6 months) and current CD4% (<15%, 15–24%, ≥25%). CD4%-stratified mortality rates were estimated separately for children who did not experience a clinical event (“background” mortality) and for children who experienced an event, including “acute” mortality (≤30 days post-event) and “later” mortality (>30 days post-event). Results Among 847 children (median enrollment age: 4.8 months; median pre-ART follow-up: 10.8 months; 603 (71%) with ≥1 CD4% recorded), event rates were comparable for those aged <6 and ≥6 months. Current CD4% was associated with risk of WHO4 events for children <6 months old, and with all evaluated events for children ≥6 months old (p<0.05). “Background” mortality was 3.7–8.4/100py. “Acute” mortality (≤30 days post-event) was 33.8/100py (after TB) and 41.1/100py (after WHO3 or WHO4). “Later” mortality (>30 days post-event) ranged by CD4% from 4.7–29.1/100py. Conclusions In treatment-naïve, HIV-infected infants, WHO3, WHO4, and TB events were common before and after 6 months of age and led to substantial increases in mortality. Early infant HIV diagnosis and treatment are critically important, regardless of CD4%. PMID:24378935

    Background: Predicting long-term survival after admission to hospital is helpful for clinical, administrative and research purposes. The Hospital-patient One-year Mortality Risk (HOMR) model was derived and internally validated to predict the risk of death within 1 year after admission. We conducted an external validation of the model in a large multicentre study. Methods: We used administrative data for all nonpsychiatric admissions of adult patients to hospitals in the provinces of Ontario (2003–2010) and Alberta (2011–2012), and to the Brigham and Women’s Hospital in Boston (2010–2012) to calculate each patient’s HOMR score at admission. The HOMR score is based on a set of parameters that captures patient demographics, health burden and severity of acute illness. We determined patient status (alive or dead) 1 year after admission using population-based registries. Results: The 3 validation cohorts (n = 2 862 996 in Ontario, 210 595 in Alberta and 66 683 in Boston) were distinct from each other and from the derivation cohort. The overall risk of death within 1 year after admission was 8.7% (95% confidence interval [CI] 8.7% to 8.8%). The HOMR score was strongly and significantly associated with risk of death in all populations and was highly discriminative, with a C statistic ranging from 0.89 (95% CI 0.87 to 0.91) to 0.92 (95% CI 0.91 to 0.92). Observed and expected outcome risks were similar (median absolute difference in percent dying in 1 yr 0.3%, interquartile range 0.05%–2.5%). Interpretation: The HOMR score, calculated using routinely collected administrative data, accurately predicted the risk of death among adult patients within 1 year after admission to hospital for nonpsychiatric indications. Similar performance was seen when the score was used in geographically and temporally diverse populations. The HOMR model can be used for risk adjustment in analyses of health administrative data to predict long-term survival among hospital patients

    Considering the breadth of perspectives in security research among Europeans, as exemplified within this publication, one may certainly note that a tremendous development of this young discipline has occurred in a short period of time. Only three years have passed since the discipline was promoted to an individual theme within the specific programme on `Cooperation' of the European Commission FP7. Since then, a conceptual framework has been established and the first collaborative projects have been executed on different levels, all at an impressive pace. Although the future of security research will remain closely linked to the political will of EU member states, the established base will serve as a solid foundation for the further development of the discipline on a European scale.

    This compilation of papers in this book represents approximately half of the works discussed at the MS&T 2010 symposium entitled Tools, Models, Databases, and Simulation Tools Developed and Needed to Realize the Vision of Integrated Computational Materials Engineering at Materials Science & Technology wherein five sessions comprised of 33 presentations was organized. The goal of the symposium was two fold To provide a forum in which current state-of-the-art methods for ICME (e.g., information informatics, experimentation, and modeling) could be openly discussed and critiqued by not only materials scientist but also structural engineers/researchers, component designers, industrial leaders and government program managers. To leave the symposium and in particular the panel discussion with a clear idea of the gaps and barriers (both technical, cultural and economical) that must be addressed in order for ICME to fully succeed. The organizers felt that these goals were met, as particularly evident by the standing room only attendance during a lively panel discussion session at the end of the Symposium. However it is the firm belief of the editors of this book that this symposium was merely a start in the right direction, and that subsequent conferences/symposium (e.g., First World Congress on Integrated Computational Materials Engineering to be held July 10-14, 2011 at Seven Springs Mountain Resort in Pennsylvania) must work hard to ensure that a truly diverse, multidisciplinary, community of researchers and practitioners are present and have ample opportunity for interaction. This will ensure that a proper balance between push and pull disciplines and technologies is maintained so that this emerging focus area, Integrated Computational Materials Engineering (ICME), has the greatest potential for success and impact on "system-level" payoffs. Similarly, a pro-active approach is required to reform historical modes of operation in industry, government and the academic sectors so as to facilitate multidisciplinary collaboration and to clearly articulate the vision and scope of ICME.

    Some say that an increase in security does not necessarily mean a further encroachment on privacy - indeed, security is necessary to protect personal data and our privacy. Networks must be secure, our personal devices, reliable, dependable and trustworthy. But security is a multifaceted term, with many dimensions. We are of the view that an increase in security most likely will encroach upon our privacy in an ambient intelligence world. Surveillance cameras will continue to proliferate. We assume that, whatever the law is, whatever privacy protections government and business say they honour, our telecommunications, e-mails and Internet usage will be monitored to an increasing degree. The same will be true of our interfaces with the world of ambient intelligence.

    It is often held that things should always be made simple, which presumes that either that they can always be made simple or that all the jetisoned logic doesn't matter anyway. Alledgedly, anything should be explainable so that anyone can understand it. Don't get bogged down in dreary details. It should be effortless for the reader: low-dimensional systems exhibit complex behaviour while high-dimensional systems exhibit simple behaviour (to return to our prolegomonal opening), competition is a universal solution, demand must increase as price falls, and everything under the sun neatly fits a power law. Or so the story goes...

    showing the increase, considering latency and the length of the observation period. Of further interest are results relating to diseases of the urinary tract such as kidney failure in the NPCSs of Basso bacino del fiume Chienti, Taranto, Milazzo and Priolo. Overall, the results discussed above are consistent with the previous findings pertaining to mortality for 1995-2002. The present analysis also introduces a new element - the study of cancer incidence and hospital discharges - which can tell us a great deal about diseases with high survival rates or non lethal ones. The first is the case of thyroid cancer, which presents increases in both databases and for both genders in a number of NPCSs (Brescia-Caffaro, Laghi di Mantova, Milazzo, Sassuolo- Scandiano and Taranto). The study of cancer incidence and hospital discharges also revealed cancer excesses for melanoma, breast cancer and non Hodgkin lymphoma in Brescia-Caffaro NPCS where PCBs (Polychlorinated biphenyl) are the site's main pollutant. PCBs, according to the 2013 evaluation of the International Agency for Research on Cancer, are ascertained human carcinogens for melanoma and probable carcinogens for breast cancer and non-Hodgkin lymphoma. The results pertaining to cancer incidence in the 17 NPCSs can also be presented using rankings by area or disease analyzed by a multivariate hierarchical Bayesian model. These rankings reveal an overlapping of credibility intervals, such that it is not possible to speak of a limited number of cancer sites or of certain NPCSs as being particularly affected. Every NPCS, therefore, must be considered individually and ordering them by ranking of cancer incidence wouldn't be appropriate. Data collected concerning some of the NPCSs in the context of the SENTIERI Project is so conclusive that remediation measures can immediately be put in place. This is the case in the Biancavilla and Brescia-Caffaro NPCSs. A similar conclusion can be drawn for complex locations such as Taranto

    Background Varicella universal vaccination (UV) has been implemented in many countries for several years. Nevertheless, varicella UV remains debated in Europe and few data are available on the real burden of infection. We assessed the burden of varicella in Belgium through analysis of hospitalised cases during a 1-year period. Methods Data on children admitted to hospital with varicella were collected through a national network from November 2011 to October 2012. Inclusion criteria were either acute varicella or related complications up to 3 weeks after the rash. Results Participation of 101 hospitals was obtained, covering 97.7% of the total paediatric beds in Belgium. 552 children were included with a median age of 2.1 years. Incidence of paediatric varicella hospitalisations reached 29.5/105 person-years, with the highest impact among those 0–4 years old (global incidence and odds of hospitalisation: 79/105 person-years and 1.6/100 varicella cases, respectively). Only 14% (79/552) of the cohort had an underlying chronic condition. 65% (357/552) of children had ≥1 complication justifying their admission, 49% were bacterial superinfections and 10% neurological disorders. Only a quarter of children (141/552) received acyclovir. Incidence of complicated hospitalised cases was 19/105 person-years. Paediatric intensive care unit admission and surgery were required in 4% and 3% of hospitalised cases, respectively. Mortality among Belgian paediatric population was 0.5/106 and fatality ratio 0.2% among our cohort. Conclusions Varicella demonstrated a substantial burden of disease in Belgian children, especially among the youngest. Our thorough nationwide study, run in a country without varicella UV, offers data to support varicella UV in Belgium. PMID:26130380

    This chapter provides a brief wrap-up of the task group report and focuses on the overall conclusions and recommendations for future work for the CAWAPI and VFE-2 facets beyond the task group. The overall conclusion is that the Technology Readiness Level (TRL) of CFD solvers has been improved in predicting the flow-physics of vortex-dominated flows during the work of the task group, by having flight and wind-tunnel data available for comparison. Moreover, like all good scientific studies, this task group has identified flight conditions on the F-16XL airplane or wind-tunnel test conditions for a specific leading-edge radius on the 65 delta-wing model where the TRL still needs to be increased.

    In the task of quantum state exclusion, we consider a quantum system prepared in a state chosen from a known set. The aim is to perform a measurement on the system which can conclusively rule that a subset of the possible preparation procedures cannot have taken place. We ask what conditions the set of states must obey in order for this to be possible and how well we can complete the task when it is not. The task of quantum state discrimination forms a subclass of this set of problems. Within this paper, we formulate the general problem as a semidefinite program (SDP), enabling us to derive sufficient and necessary conditions for a measurement to be optimal. Furthermore, we obtain a necessary condition on the set of states for exclusion to be achievable with certainty, and we give a construction for a lower bound on the probability of error. This task of conclusively excluding states has gained importance in the context of the foundations of quantum mechanics due to a result from Pusey, Barrett, and Rudolph (PBR). Motivated by this, we use our SDP to derive a bound on how well a class of hidden variable models can perform at a particular task, proving an analog of Tsirelson's bound for the PBR experiment and the optimality of a measurement given by PBR in the process. We also introduce variations of conclusive exclusion, including unambiguous state exclusion, and state exclusion with worst-case error.

    Surgical audit is a systematic, critical analysis of the quality of surgical care that is reviewed by peers against explicit criteria or recognized standards. It is used to improve surgical practice with the ultimate goal of improving patient care. As the pattern of surgical care is different in the developing world, we analyzed mortalities in a referral medical institute of India to suggest interventions for improvement. An analysis of total admissions, different surgeries, and mortalities over 1 year in an urban referral medical institute of northern India was performed, followed by “peer review” of the mortalities. Mortality rates as outcomes and classification was done to provide comparative results. Of 10,005 surgical patients, 337 (male = 221, female = 116) deaths were reported over 1 year. The overall mortality rate was 3.36%, while mortality in operative cases was 1.76%. Total deaths were classified into (1) Viable: 153 (45%), (2) Nonviable: 174 (52%), and (3) Indeterminate: 10 (3%). Exclusion of the nonviable group reduced the mortality rate from 3.36% to 1.62%. Trauma was the major cause of mortality (n = 235; 70%) as compared to other surgical patients (n = 102; 30%). Increased mortality was also associated with emergency procedures (3.66%) as compared to elective surgeries (0.34%). In conclusion, audit of mortality and morbidity helps in initiating and implementing preventive strategies to improve surgical practice and patient care, and to reduce mortality rates. The mortality and morbidity forum is an important educational activity. It should be considered a mandatory activity in all postgraduate training programs. PMID:26414825

    Bolivia, Haiti, and Peru have infant mortality levels as high as those of the developed countries a century ago. The decline of general and especially infant mortality experienced in Latin America beginning in the 1940s was uneven throughout the continent. Cuba's infant mortality rate declined by 86% between 1940-80, but Peru's declined by only 48% despite its higher initial level. In 1984, 34% of all deaths in Peru were to children under 1 year and about 21% were to children 1-5 years old. Socioeconomic factors are the major explanation of Peru's poor infant mortality levels. Regional and social disparities in access to housing, food, urban infrastructure, and other vital goods and services are reflected in infant mortality statistics. Infant mortality has declined in both rural and urban areas, but the magnitude of the decline was much greater in urban areas. Between 1960-75, the infant mortality rate declined from 133 to 80/1000 live births in urban areas, but only from 180 to 150/1000 in rural areas. Investment in the infrastructure and services of the cities during the 1950s and 60s was not matched by any significant investment in rural infrastructure. Rural-urban mortality differentials are not as profound in countries which distribute public investment more evenly between rural and urban areas. Cuba's rural infant mortality rate is only 16% greater than its urban rate, while Peru's rural rate is 47% higher. The rural-urban differential in Peru hides a steep gap between the metropolitan zone of Lima-Callao, which has an infant mortality rate of 55/1000, and that of all cities, which have a rate 45% higher. Metropolitan Lima has the highest levels of living in Peru, including the highest incomes and best housing and service infrastructure. A majority of Peru's economic and industrial development has been concentrated in Lima. Peru's infant mortality differentials are also striking at the departmental level.

    Osteoporosis-related hip fractures represent a substantial cause of mortality and morbidity in industrialized countries like Austria. Identification of groups at high risk for mortality after hip fracture is crucial for health policy decisions. To determine in-hospital, long-term, and excess mortality after osteoporosis-related hip fracture in Austrian patients, we conducted a retrospective cohort analysis of pseudonymized invoice data from Austrian social insurance authorities covering roughly 98 % of the entire population. The data set included 31,668 subjects aged 50 years and above sustaining a hip fracture between July 2008 and December 2010 with follow-up until June 2011, and an age-, gender-, and regionally matched control population without hip fractures (56,320 subjects). Kaplan-Meier and Cox hazard regression analyses served to determine unadjusted and adjusted mortality rates: Unadjusted all-cause 1-year mortality amounted to 20.2 % (95 % CI: 19.7-20.7 %). Males had significantly higher long-term, in-hospital, and excess mortality rates than females, but younger males exhibited lower excess mortality than their female counterparts. Advanced age correlated with increased long-term and in-hospital mortality, but lower excess mortality. Excess mortality, particularly in males, was highest in the first 6 months after hip fracture, but remained statistically significantly elevated throughout the observation period of 3 years. Longer hospital stay per fracture was correlated with mortality reduction in older patients and in patients with more subsequent fractures. In conclusion, more efforts are needed to identify causes and effectively prevent excess mortality especially in male osteoporosis patients. PMID:24989776

    Objective: Data on long-term use of secondary prevention medications following stroke are limited. The Adherence eValuation After Ischemic stroke–Longitudinal (AVAIL) Registry assessed patient, provider, and system-level factors influencing continuation of prevention medications for 1 year following stroke hospitalization discharge. Methods: Patients with ischemic stroke or TIA discharged from 106 hospitals participating in the American Heart Association Get With The Guidelines–Stroke program were surveyed to determine their use of warfarin, antiplatelet, antihypertensive, lipid-lowering, and diabetes medications from discharge to 12 months. Reasons for stopping medications were ascertained. Persistence was defined as continuation of all secondary preventive medications prescribed at hospital discharge, and adherence as continuation of prescribed medications except those stopped according to health care provider instructions. Results: Of the 2,880 patients enrolled in AVAIL, 88.4% (2,457 patients) completed 1-year interviews. Of these, 65.9% were regimen persistent and 86.6% were regimen adherent. Independent predictors of 1-year medication persistence included fewer medications prescribed at discharge, having an adequate income, having an appointment with a primary care provider, and greater understanding of why medications were prescribed and their side effects. Independent predictors of adherence were similar to those for persistence. Conclusions: Although up to one-third of stroke patients discontinued one or more secondary prevention medications within 1 year of hospital discharge, self-discontinuation of these medications is uncommon. Several potentially modifiable patient, provider, and system-level factors associated with persistence and adherence may be targets for future interventions. PMID:21900638

    The pathophysiology and time course of an individual converting from asymptomatic peripheral artery disease (PAD) to symptomatic claudication is unclear. The objectives of this study were: (1) to characterize the extent of atherosclerotic disease in individuals with an abnormal ankle-brachial index (ABI), but without claudication; and over 1 year of follow-up to (2) evaluate the progression of PAD using ultrasound imaging, (3) determine changes in the ABI and leg pain symptoms, and (4) correlate PAD progression with changes in the ABI and leg symptoms. We hypothesized that PAD progression would be associated with the development of claudication and changes in the ABI, 6-minute walk distance (6-MWD), and walking quality of life. Individuals with a reduced ABI but without typical intermittent claudication noted on community screening were invited to undergo baseline and 1-year follow-up assessment, including duplex ultrasound. The initial and repeat evaluations included measurement of the ABI, lower extremity duplex arterial mapping, and assessment of leg pain and functional status. Of the 50 people studied, 44 (88%) had significant atherosclerotic lesions in the lower extremity arteries, affecting 80 legs. A total of 33 of 50 individuals (66%) returned for the 1-year follow-up visit. On ultrasound examination, two of 18 normal legs developed PAD, and in 48 legs with PAD at baseline, 17 legs (35%) developed new or progressive lesions. Thirteen legs developed new claudication. Overall, there was no significant worsening in the ABI, 6-MWD, or the Walking Impairment Questionnaire (WIQ). However, legs with new lesions or lesion progression were significantly more likely to develop claudication, and the 13 legs (seven subjects) developing claudication showed a significant decline in the 6-MWD. In conclusion, these data indicate that a significant number of people with asymptomatic PAD show progression over 1 year, that such individuals are more likely to develop

    The objectives was to assess the determinants of and rates of abortion, stillbirth, and infant mortality for a cohort of pregnant women from slums in New Delhi, Calcutta, and Madras, India and rural slums in Hyderabad, Varanasi, and Chandigarh, India in 1981. The relationship of low birthweight (LBW) and high risk pregnancies to social, environmental, nutritional, cultural, and biological factors was of interest. The results showed variation both between and within urban and rural areas. Rural pregnancy outcome showed fewer LBWs and perinatal and neonatal mortality. Perinatal, neonatal, and infant mortality rates were consistent with prior findings. There was a demonstrated need for prenatal care and referral due to the 10-12% with a poor obstetric history and the significant number with anemia, bleeding, hypertension, toxemia, and urinary tract infections during this pregnancy. Many women were malnourished (body weight 40 kg, height 145 cm, and midarm circumference of 22.5 cm. These women can be identified as high risk. Other risk factors identified were women with disadvantageous personal habits: smoking, alcohol use, tobacco chewing, and working. 10-25% of pregnancies were not registered even though the prenatal clinic was accessible and outreach was provided. 20% completed the recommended number of prenatal visits. 75-85% visited at least once and sometimes more often. Screening for high risk must be done at the 1st visit. Women had strong feelings about the preference for a Dai during delivery and for place of delivery. Poor training of health workers was reflected in the lack of adequate sanitation during the birthing process. Neonatal units were lacking and primary care absent. 10-14% of births were preterm of which 50% occurred at 36 weeks. Multiple regression identified risk factors for fetal and neonatal mortality and LBW as maternal age, preterm birth, maternal anemia, previous preterm or LBW, birth interval, and previous fetal and neonatal mortality

    Cardiac resynchronisation therapy (CRT) is an established treatment option for heart failure patients with electromechanical dyssynchrony. Between 2008 and 2010, the Heart Failure Association (HFA) and the European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC) initiated the European CRT survey to describe the current practice and short-term clinical outcome associated with CRT implantations in 13 countries. One year follow-up data from 150 patients collected in 10 Austrian centres are presented in comparison to the total 1,969 patients enrolled throughout Europe. In most cases (n = 120), CRT-D devices were implanted, while CRT-P devices were used in only 23 %. After 12 ± 3 months, mortality and hospitalisation rates reached 10 and 37 %, respectively. New York Heart Association (NYHA) functional classes improved significantly: NYHA I/II/III/IV were found before implantation in 2/20/71/7 % and after 1 year follow-up in 35/51/9/5 % of the patients, respectively. Left ventricular ejection fraction improved from 27 ± 8 % to 35 ± 10 %, left ventricular end-diastolic diameters were reduced from 65 ± 10 mm to 59 ± 5 mm. Median NT-proBNP was reduced from 1,886 to 997 pg/ml, QRS duration diminished from 158 ± 34 to 147 ± 27 ms. In conclusion, the Austrian data from the CRT survey confirms the efficacy of CRT in heart failure patients, but outlines that these patients still suffer from a high mortality and cardiovascular (CV) hospitalisation rate.

    INTRODUCTION: Safe, effective weight loss with resolution of comorbidities has been convincingly demonstrated with bariatric surgery in the aged obese. They, however, lose less weight than younger individuals. It is not known if degree of weight loss is influenced by the choice of bariatric procedure. The aim of this study was to compare the degree of weight loss between laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients above the age of 50 years at 1 year after surgery. MATERIALS AND METHODS: A retrospective analysis was performed of all patients more than 50 years of age who underwent LSG or LRYGB between February 2012 and July 2013 with at least 1 year of follow-up. Data evaluated at 1 year included age, sex, weight, body mass index (BMI), mean operative time, percentage of weight loss and excess weight loss, resolution/remission of diabetes, morbidity and mortality. RESULTS: Of a total of 86 patients, 54 underwent LSG and 32 underwent LRYGB. The mean percentage of excess weight loss at the end of 1 year was 60.19 ± 17.45 % after LSG and 82.76 ± 34.26 % after LRYGB (P = 0.021). One patient developed a sleeve leak after LSG, and 2 developed iron deficiency anaemia after LRYGB. The remission/improvement in diabetes mellitus and biochemistry was similar. CONCLUSION: LRYGB may offer better results than LSG in terms of weight loss in patients over 50 years of age. PMID:27279392

    Objective A measure that identifies patients who are at high risk of mortality after prolonged ventilation will help physicians communicate prognosis to patients or surrogate decision-makers. Our objective was to develop and validate a prognostic model for 1-year mortality in patients ventilated for 21 days or more. Design Prospective cohort study. Setting University-based tertiary care hospital Patients 300 consecutive medical, surgical, and trauma patients requiring mechanical ventilation for at least 21 days were prospectively enrolled. Measurements and Main Results Predictive variables were measured on day 21 of ventilation for the first 200 patients and entered into logistic regression models with 1-year and 3-month mortality as outcomes. Final models were validated using data from 100 subsequent patients. One-year mortality was 51% in the development set and 58% in the validation set. Independent predictors of mortality included requirement for vasopressors, hemodialysis, platelet count ≤150 ×109/L, and age ≥50. Areas under the ROC curve for the development model and validation model were 0.82 (se 0.03) and 0.82 (se 0.05) respectively. The model had sensitivity of 0.42 (se 0.12) and specificity of 0.99 (se 0.01) for identifying patients who had ≥90% risk of death at 1 year. Observed mortality was highly consistent with both 3- and 12-month predicted mortality. These four predictive variables can be used in a simple prognostic score that clearly identifies low risk patients (no risk factors, 15% mortality) and high risk patients (3 or 4 risk factors, 97% mortality). Conclusions Simple clinical variables measured on day 21 of mechanical ventilation can identify patients at highest and lowest risk of death from prolonged ventilation. PMID:18552692

    Objective: Using estimates from the 2013 Global Burden of Disease (GBD) study, we update evidence on disparities in under-five child injury mortality between developing and developed countries from 1990 to 2013. Methods: Mortality rates were accessed through the online visualization tool by the GBD study 2013 group. We calculated percent change in child injury mortality rates between 1990 and 2013. Data analysis was conducted separately for <1 year and 1–4 years to specify age differences in rate changes. Results: Between 1990 and 2013, over 3-fold mortality gaps were observed between developing countries and developed countries for both age groups in the study time period. Similar decreases in injury rates were observed for developed and developing countries (<1 year: −50% vs. −50% respectively; 1–4 years: −56% vs. −58%). Differences in injury mortality changes during 1990–2013 between developing and developed nations varied with injury cause. There were greater reductions in mortality from transport injury, falls, poisoning, adverse effects of medical treatment, exposure to forces of nature, and collective violence and legal intervention in developed countries, whereas there were larger decreases in mortality from drowning, exposure to mechanical forces, and animal contact in developing countries. Country-specific analysis showed large variations across countries for both injury mortality and changes in injury mortality between 1990 and 2013. Conclusions: Sustained higher child injury mortality during 1990–2013 for developing countries merits the attention of the global injury prevention community. Countries that have high injury mortality can benefit from the success of other countries. PMID:27399740

    OBJECTIVES: To evaluate the risk of cancer and other diseases among workers engaged in aircraft manufacturing and potentially exposed to compounds containing chromate, trichloroethylene (TCE), perchloroethylene (PCE), and mixed solvents. METHODS: A retrospective cohort mortality study was conducted of workers employed for at least 1 year at a large aircraft manufacturing facility in California on or after 1 January 1960. The mortality experience of these workers was determined by examination of national, state, and company records to the end of 1996. Standardised mortality ratios (SMRs) were evaluated comparing the observed numbers of deaths among workers with those expected in the general population adjusting for age, sex, race, and calendar year. The SMRs for 40 cause of death categories were computed for the total cohort and for subgroups defined by sex, race, position in the factory, work duration, year of first employment, latency, and broad occupational groups. Factory job titles were classified as to likely use of chemicals, and internal Poisson regression analyses were used to compute mortality risk ratios for categories of years of exposure to chromate, TCE, PCE, and mixed solvents, with unexposed factory workers serving as referents. RESULTS: The study cohort comprised 77,965 workers who accrued nearly 1.9 million person-years of follow up (mean 24.2 years). Mortality follow up, estimated as 99% complete, showed that 20,236 workers had died by 31 December 1996, with cause of death obtained for 98%. Workers experienced low overall mortality (all causes of death SMR 0.83) and low cancer mortality (SMR 0.90). No significant increases in risk were found for any of the 40 specific cause of death categories, whereas for several causes the numbers of deaths were significantly below expectation. Analyses by occupational group and specific job titles showed no remarkable mortality patterns. Factory workers estimated to have been routinely exposed to chromate were

    Abstract Objective: To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Methods: Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. Results: 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score <7 and day care attendance. The multivariate analysis showed that artificial feeding is the factor most often associated to otitis media with effusion. Conclusions: Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. PMID:26559603

    Liver cirrhosis is a known risk factor for postoperative mortality in patients undergoing cardiac surgery. Clinical assessment of liver cirrhosis using the widely accepted Child-Pugh (CP) score is thus vital for evaluation of surgical options and perioperative care. However, detailed mortality rates as a consequence of liver cirrhosis are unclear. This review aimed to stratify the risk of short-term (<30 days) and overall (up to 10 years) mortality after cardiac surgery in patients with liver cirrhosis, classified by the CP score. Thus, PubMed, Embase, CINAHL and the Cochrane Library were systematically reviewed by two independent investigators for studies published up to February 2014, in which mortality in cirrhotic patients, classified by the CP classification, undergoing cardiac surgery was evaluated postoperatively. A total of 993 articles were identified. After critical appraisal of 21 articles, 19 were selected for final analysis. Weighted short-term mortality of cirrhotic patients undergoing cardiac surgery was 19.3% [95% confidence interval (CI): 16.4-22.5%]. Across the different CP groups, short-term mortality appeared to be 9.0% (95% CI: 6.6-12.2%), 37.7% (95% CI: 30.8-44.3%) and 52.0% (95% CI: 33.5-70.0%) in Groups A, B and C, respectively. Weighted overall mortality within 1 year was 42.0% (95% CI: 36.0-48.3%) in all cirrhotic patients. Subdivided in groups, overall mortality within that 1 year was 27.2% (95% CI: 20.9-34.7%), 66.2% (95% CI: 54.3-76.3%) and 78.9% (95% CI: 56.1-92.1%) in Groups A, B and C, respectively. In conclusion, short-term mortality is considerably increased in patients with liver cirrhosis CP class B and C. Overall mortality is significantly high in all classes of liver cirrhosis.

    Objectives. This study sought to estimate total health care costs for mild, moderate, and severe pediatric traumatic brain injury (TBI) and to compare individual- and population-level costs across levels of TBI severity. Methods. Using 2007 to 2010 MarketScan Commercial Claims and Encounters data, we estimated total quarterly health care costs 1 year after TBI among enrollees (aged < 18 years). We compared costs across levels of TBI severity using generalized linear models. Results. Mild TBI accounted for 96.6% of the 319 103 enrollees with TBI; moderate and severe TBI accounted for 1.7% and 1.6%, respectively. Adjusted individual health care costs for moderate and severe TBI were significantly higher than mild TBI in the year after injury (P < .01). At the population level, moderate and severe TBI costs were 88% and 75% less than mild TBI, respectively. Conclusions. Individually, moderate and severe TBI initially generated costs that were markedly higher than those of mild TBI. At the population level, costs following mild TBI far exceeded those of more severe cases, a result of the extremely high population burden of mild TBI. PMID:26270293

    Purpose. To examine the associations of optimism and pessimism with all-cause, cardiovascular disease (CVD), coronary heart disease (CHD), and cancer mortality in a population-based sample of older men and women followed ≤12 years. Methods. 367 men and 509 women aged ≥50 from the Rancho Bernardo Study attended a 1999-2002 research clinic visit when demographic, behavioral, and medical history were obtained and completed a 1999 mailed survey including the Life Orientation Test-Revised (LOT-R). Mortality outcomes were followed through 2012. Results. Average age at baseline was 74.1 years; during follow-up (mean = 8.1 years), 198 participants died, 62 from CVD, 22 from CHD, and 49 from cancer. Total LOT-R, optimism and pessimism scores were calculated. Participants with the highest optimism were younger and reported less alcohol use and smoking and more exercise. Cox proportional hazard models showed that higher total LOT-R and optimism, but not pessimism scores, were associated with reduced odds of CHD mortality after adjusting for age, sex, alcohol, smoking, obesity, physical exercise, and medication (HR = 0.86, 95% CI = 0.75, 0.99; HR = 0.77, 95% CI = 0.61, 0.99, resp.). No associations were found for all-cause, CVD, or cancer mortality. Conclusions. Optimism was associated with reduced CHD mortality in older men and women. The association of positive attitudes with mortality merits further study.

    Background While some prediction models have been developed for diabetic populations, prediction rules for mortality in diabetic dialysis patients are still lacking. Therefore, the objective of this study was to identify predictors for 1-year mortality in diabetic dialysis patients and use these results to develop a prediction model. Methods Data were used from the Netherlands Cooperative Study on the Adequacy of Dialysis (NECOSAD), a multicenter, prospective cohort study in which incident patients with end stage renal disease (ESRD) were monitored until transplantation or death. For the present analysis, patients with DM at baseline were included. A prediction algorithm for 1-year all-cause mortality was developed through multivariate logistic regression. Candidate predictors were selected based on literature and clinical expertise. The final model was constructed through backward selection. The model's predictive performance, measured by calibration and discrimination, was assessed and internally validated through bootstrapping. Results A total of 394 patients were available for statistical analysis; 82 (21%) patients died within one year after baseline (3 months after starting dialysis therapy). The final prediction model contained seven predictors; age, smoking, history of macrovascular complications, duration of diabetes mellitus, Karnofsky scale, serum albumin and hemoglobin level. Predictive performance was good, as shown by the c-statistic of 0.810. Internal validation showed a slightly lower, but still adequate performance. Sensitivity analyses showed stability of results. Conclusions A prediction model containing seven predictors has been identified in order to predict 1-year mortality for diabetic incident dialysis patients. Predictive performance of the model was good. Before implementing the model in clinical practice, for example for counseling patients regarding their prognosis, external validation is necessary.

    Objectives. We analyzed trends in maternal, newborn, and child mortality in Chile between 1990 and 2004, after the introduction of national interventions and reforms, and examined associations between trends and interventions. Methods. Data were provided by the Chilean Ministry of Health on all pregnancies between 1990 and 2004 (approximately 4 000 000). We calculated yearly maternal mortality ratios, stillbirth rates, and mortality rates for neonates, infants (aged > 28 days and < 1 year), and children aged 1 to 4 years. We also calculated these statistics by 5-year intervals for Chile's poorest to richest district quintiles. Results. During the study period, the maternal mortality ratio decreased from 42.1 to 18.5 per 100 000 live births. The mortality rate for neonates decreased from 9.0 to 5.7 per 1000 births, for infants from 7.8 to 3.1 per 1000 births, and for young children from 3.1 to 1.7 per 1000 live births. The stillbirth rate declined from 6.0 to 5.0 per 1000 births. Disparities in these mortality statistics between the poorest and richest district quintiles also decreased, with the largest mortality reductions in the poorest quintile. Conclusions. During a period of socioeconomic development and health sector reforms, Chile experienced significant mortality and inequity reductions. PMID:19443831

    Objectives. We examined the relationship between 4 low-risk behaviors—never smoked, healthy diet, adequate physical activity, and moderate alcohol consumption—and mortality in a representative sample of people in the United States. Methods. We used data from 16958 participants aged 17 years and older in the National Health and Nutrition Examination Survey III Mortality Study from 1988 to 2006. Results. The number of low-risk behaviors was inversely related to the risk for mortality. Compared with participants who had no low-risk behaviors, those who had all 4 experienced reduced all-cause mortality (adjusted hazard ratio [AHR]=0.37; 95% confidence interval [CI]=0.28, 0.49), mortality from malignant neoplasms (AHR=0.34; 95% CI=0.20, 0.56), major cardiovascular disease (AHR=0.35; 95% CI=0.24, 0.50), and other causes (AHR=0.43; 95% CI=0.25, 0.74). The rate advancement periods, representing the equivalent risk from a certain number of years of chronological age, for participants who had all 4 high-risk behaviors compared with those who had none were 11.1 years for all-cause mortality, 14.4 years for malignant neoplasms, 9.9 years for major cardiovascular disease, and 10.6 years for other causes. Conclusions. Low-risk lifestyle factors exert a powerful and beneficial effect on mortality. PMID:21852630

    Conflicting results have been reported about the prognostic impact of left bundle branch block (LBBB) after transcatheter aortic valve implantation (TAVI). The aim of this study was to evaluate the impact of LBBB after TAVI on left ventricular (LV) function and remodeling and on 1-year outcomes. Of 101 TAVI patients, 9 were excluded. All complications were evaluated according to the Valve Academic Research Consortium 2 definition. Of 92 patients, 34 developed LBBB without more advanced myocardial damage or inflammation biomarkers in comparison with patients without LBBB. The only predictor of new LBBB was larger baseline LV end-diastolic volume. LBBB plus advanced atrioventricular block was strongly correlated with permanent pacemaker implantation (p <0.0001). Patients with LBBB had a higher rate of permanent pacemaker implantation at 30 days (59% vs 19%, p <0.0001) and less recovery of LV systolic function and a trend toward a lower rate of LV reverse remodeling at 1 year. The development of acute kidney injury and the logistic European System for Cardiac Operative Risk Evaluation score were associated with poor outcomes (all-cause mortality and heart failure) (hazard ratio 6.86, 95% confidence interval 2.51 to 18.74, p <0.0001, and hazard ratio 1.04, 95% confidence interval 1.01 to 1.08, p = 0.021, respectively), but not LBBB. In conclusion, after TAVI, 37% of patients developed new LBBB without more advanced myocardial damage or inflammation biomarkers. LBBB was associated with a higher rate of permanent pacemaker implantation, which negatively affected the recovery of LV systolic function. The development of acute kidney injury, rather than LBBB, increases the 1-year risk for mortality and hospitalization for heart failure. PMID:25937352

    Recent controversy over philosophical advocacy of infanticide (or the comically-styled euphemism 'postnatal abortion') reveals a surprisingly common premise uniting many of the opponents and supporters of the practice. This is the belief that the moral status of the early fetus or embryo with respect to a right to life is identical to that of a newly born or even very young baby. From this premise, infanticidists and strong anti-abortionists draw opposite conclusions, the former that the healthy newly born have no inherent right to life and the latter that minute embryos and the very early fetus have the same right to life as young babies. (Indeed strong anti-abortionists tend to regard this right to life as identical to that possessed by adult humans.) This paper argues that these opposed conclusions are both deeply implausible and that the implausibility resides in the common premise. The argument requires some attention to the structure of the philosophical case underpinning the supposed vice of speciesism that has been given intellectual currency by many philosophers, most notably Peter Singer, and also to the reasoning behind the strong anti-abortionist adoption of the common premise.

    It is believed that to build a robust reasoning logic to make probabilistic inferences in forensic science from a merely mathematical or logistical viewpoint is not enough. Mathematical logic is the positive science of reasoning and as for that it is only interested in the positive calculus of its validity, regardless any prior ontological assumption. But without a determined ontology and epistemology which imply to define the concepts that they will use, it seems difficult that the proposed scientifically correct mathematical solution be successful as a European standard for making conclusions in forensic reports because it has to be based on judicial language. Forensic experts and Courts are not interested in the development of a positive science but in a practical science: in clarifying whether certain known facts are related to a possible crime. Therefore, not only the coherence of the demonstrative logic reasoning used (logic of propositions) is important, but also the precision of the concepts used by language and consistency among them in reasoning (logic of concepts). There is a linguistic level essential for a successful communication between the forensic practitioner and the Court which is mainly related, in our opinion, to semantics and figures of speech. The first one is involved because words used in forensic conclusions often have different meanings - it is said that they are polysemic - and the second one because there is often metonymy as well. Besides, semantic differences among languages regarding words with the same etymological root add another difficulty for a better mutual understanding. The two main European judicial systems inherit a wide and deep culture related to evidence in criminal proceedings and each of them has coined their own terminology but there are other two more abstract levels such as logical and epistemological, where we can find solid arguments by which terms used at legal level on conclusions of forensic reports could be

    The most recent pionic--hydrogen experiment marks the completion of a whole series of measurements, the main goal of which was to provide conclusive data on pion--nucleon interaction at threshold for comparison with calculations from Chiral perturbation theory. The precision achieved for hadronic shift and broadening of 0.2% and 2%, respectively, became possible by comprehensive studies of cascade effects in hydrogen and other light exotic atoms including results from the last years of LEAR operation. In order to obtain optimum conditions for the Bragg crystal spectrometer, the cyclotron trap II has been used to provide a suitable X--ray source. To characterize the bent crystal spectrometer, the cyclotron trap has been modified to operate as an electron--cyclotron resonance source, which produces with high intensity narrow X-ray transitions in the few keV range originating from highly charged ions.

    OAK-B135 The NWCC Transmission Case Studies Conclusions Summary In the spring of 1999, the Utility Wind Interest Group (UWIG), with the cooperation of the National Wind Coordinating Committee (NWCC), conducted a forum on transmission issues associated with the production of energy from wind. As a result of this forum, a number of issues were identified which, if successfully resolved, could help reduce barriers to the future expansion of wind power. The NWCC, being a multi-stakeholder group, was in an ideal position to conduct follow-up activities among a cross-section of the interested parties. The follow-up activities took the form of three case studies in the areas of interest identified by forum participants: (1) Transmission policy and pricing; (2) ''Virtual wheeling'' arrangements; and, (3) Transmission system improvements. The case studies provide an interesting snapshot in time dealing with a range of issues associated with scheduled or planned regulatory and restructuring proceedings related to energy transmission. The NWCC Transmission Subcommittee and the UWIG reviewed early drafts of the case studies in November 1999. The case studies were conducted through a questionnaire and interview process with interested parties. In writing each case study, NWCC staff attempted to identify all stakeholder groups with an interest in each topic and solicit their input. While all parties do not agree on every issue presented, a serious effort has been made to present all views in an unbiased fashion. At the end of each case study, relevant conclusions are drawn and recommendations for next steps are provided where appropriate.

    Background Limited evidence exists regarding the utility of genetic risk scores (GRS) in predicting recurrent cardiovascular events after acute coronary syndrome (ACS). We sought to determine whether a GRS would predict early recurrent cardiovascular events within 1 year of ACS. Methods & Results Participants admitted with acute coronary syndromes from the RISCA, PRAXY, and TRIUMPH cohorts, were genotyped for 30 single nucleotide polymorphisms (SNPs) associated with coronary artery disease (CAD) or myocardial infarction (MI) in prior genome wide association studies. A 30 SNP CAD/MI GRS was constructed. The primary endpoint was defined as all-cause mortality, recurrent ACS or cardiac re-hospitalization within 1 year of ACS admission. Results across all cohorts for the 30 SNP CAD/MI GRS were pooled using a random-effects model. There were 1040 patients from the RISCA cohort, 691 patients from the PRAXY cohort, and 1772 patients from the TRIUMPH cohort included in the analysis and 389 occurrences of the primary endpoint of recurrent events at 1-year post-ACS. In unadjusted and fully adjusted analyses, a 30 SNP GRS was not significantly associated with recurrent events (HR per allele 0.97 (95%CI 0.91–1.03) for RISCA, HR 0.99 (95%CI 0.93–1.05) for PRAXY, 0.98 (95%CI 0.94–1.02) for TRIUMPH, and 0.98 (95%CI 0.95–1.01) for the pooled analysis). Addition of this GRS to the GRACE risk model did not significantly improve risk prediction. Conclusion The 30 MI SNP GRS was not associated with recurrent events 1-year post ACS in pooled analyses across cohorts and did not improve risk discrimination or reclassification indices. Our results suggest that the genetic etiology of early events post-ACS may differ from later events. PMID:26232166

    Objectives To identify children at risk for in-hospital mortality following tracheotomy. Design Retrospective cohort study. Setting 25 746 876 US hospitalisations for children within the Kids’ Inpatient Database 1997, 2000, 2003 and 2006. Participants 18 806 hospitalisations of children ages 0–18 years undergoing tracheotomy, identified from ICD-9-CM tracheotomy procedure codes. Main outcome measure Mortality during the initial hospitalisation when tracheotomy was performed in relation to patient demographic and clinical characteristics (neuromuscular impairment (NI), chronic lung disease, upper airway anomaly, prematurity, congenital heart disease, upper airway infection and trauma) identified with ICD-9-CM codes. Results Between 1997 and 2006, mortality following tracheotomy ranged from 7.7% to 8.5%. In each year, higher mortality was observed in children undergoing tracheotomy who were aged <1 year compared with children aged 1–4 years (mortality range: 10.2–13.1% vs 1.1–4.2%); in children with congenital heart disease, compared with children without congenital heart disease (13.1–18.7% vs 6.2–7.1%) and in children with prematurity, compared with children who were not premature (13.0–19.4% vs 6.8–7.3%). Lower mortality was observed in children with an upper airway anomaly compared with children without an upper airway anomaly (1.5–5.1% vs 9.1–10.3%). In 2006, the highest mortality (40.0%) was observed in premature children with NI and congenital heart disease, who did not have an upper airway anomaly. Conclusions Congenital heart disease, prematurity, the absence of an upper airway anomaly and age <1 year were characteristics associated with higher mortality in children following tracheotomy. These findings may assist provider communication with children and families regarding early prognosis following tracheotomy. PMID:20522454

    Background The purpose of this study is to report on the mortality of nonagenarians who underwent surgical treatment for a hip fracture, specifically in regards to preexisting comorbidities. Furthermore, we assessed the effectiveness of the Deyo score in predicting such mortality. Methods Thirty-nine patients over the age of 90 who underwent surgical repair of a hip fracture were retrospectively analyzed. Twenty-six patients (66.7%) suffered femoral neck fractures, while the remaining 13 (33.3%) presented with trochanteric type fractures. Patient charts were examined to determine previously diagnosed patient comorbidities as well as living arrangements and mobility before and after surgery. Results Deyo index scores did not demonstrate statistically significant correlations with postoperative mortality or functional outcomes. The hazard of in-hospital mortality was found to be 91% (p = 0.036) and 86% (p = 0.05) less in patients without a history of congestive heart failure (CHF) and chronic pulmonary disease (CPD), respectively. Additionally, the hazard of 90-day mortality was 88% (p = 0.01) and 81% (p = 0.024) less in patients without a history of dementia and CPD, respectively. The hazard of 1-year mortality was also found to be 75% (p = 0.01) and 80% (p = 0.01) less in patients without a history of dementia and CPD, respectively. Furthermore, dementia patients stayed in-hospital postoperatively an average of 5.3 days (p = 0.013) less than nondementia patients and only 38.5% returned to preoperative living conditions (p = 0.036). Conclusions Nonagenarians with a history of CHF and CPD have a higher risk of in-hospital mortality following the operative repair of hip fractures. CPD and dementia patients over 90 years old have higher 90-day and 1-year mortality hazards postoperatively. Dementia patients are also discharged more quickly than nondementia patients.

    Abstract Deficiency in 25-hydroxyvitamin D (25[OH]D), the main circulating form of vitamin D in blood, could be involved in the pathogenesis of acute coronary syndromes (ACS). To date, however, the possible prognostic relevance of 25 (OH)D deficiency in ACS patients remains poorly defined. The purpose of this prospective study was to assess the association between 25 (OH)D levels, at hospital admission, with in-hospital and 1-year morbidity and mortality in an unselected cohort of ACS patients. We measured 25 (OH)D in 814 ACS patients at hospital presentation. Vitamin D serum levels >30 ng/mL were considered as normal; levels between 29 and 21 ng/mL were classified as insufficiency, and levels < 20 ng/mL as deficiency. In-hospital and 1-year outcomes were evaluated according to 25 (OH)D level quartiles, using the lowest quartile as a reference. Ninety-three (11%) patients had normal 25 (OH)D levels, whereas 155 (19%) and 566 (70%) had vitamin D insufficiency and deficiency, respectively. The median 25 (OH)D level was similar in ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) patients (14.1 [IQR 9.0–21.9] ng/mL and 14.05 [IQR 9.1–22.05] ng/mL, respectively; P = .88). The lowest quartile of 25 (OH)D was associated with a higher risk for several in-hospital complications, including mortality. At a median follow-up of 366 (IQR 364–379) days, the lowest quartile of 25 (OH)D, after adjustment for the main confounding factors, remained significantly associated to 1-year mortality (P < .01). Similar results were obtained when STEMI and NSTEMI patients were considered separately. In ACS patients, severe vitamin D deficiency is independently associated with poor in-hospital and 1-year outcomes. Whether low vitamin D levels represent a risk marker or a risk factor in ACS remains to be elucidated. PMID:25984675

    Workers employed in 15 utilities that generate nuclear power in the United States have been followed for up to 18 years between 1979 and 1997. Their cumulative dose from whole-body ionizing radiation has been determined from the dose records maintained by the facilities themselves and the REIRS and REMS systems maintained by the Nuclear Regulatory Commission and the Department of Energy, respectively. Mortality in the cohort from a number of causes has been analyzed with respect to individual radiation doses. The cohort displays a very substantial healthy worker effect, i.e. considerably lower cancer and noncancer mortality than the general population. Based on 26 and 368 deaths, respectively, positive though statistically nonsignificant associations were seen for mortality from leukemia (excluding chronic lymphocytic leukemia) and all solid cancers combined, with excess relative risks per sievert of 5.67 (95% confidence interval (CI) -2.56, 30.4) and 0.596 (95% CI -2.01, 4.64), respectively. These estimates are very similar to those from the atomic bomb survivors study, though the wide confidence intervals are also consistent with lower or higher risk estimates. A strong positive and statistically significant association between radiation dose and deaths from arteriosclerotic heart disease including coronary heart disease was also observed in the cohort, with an ERR of 8.78 (95% CI 2.10, 20.0). Whle associations with heart disease have been reported in some other occupational studies, the magnitude of the present association is not consistent with them and therefore needs cautious interpretation and merits further attention. At present, the relatively small number of deaths and the young age of the cohort (mean age at end of follow-up is 45 years) limit the power of the study, but further follow-up is 45 years) limit the power of the study, but further follow-up and the inclusion of the present data in an ongoing IARC combined analysis of nuclear workers from 15

    94 maternal deaths and 1546 fetal and neonatal deaths were registered among 28,706 births at the CHU Averroes in Casablanca between 1978-80. 45% of women who deliver at the clinic are very poor and only 10% are relatively well off. Obstetrical antecedents were noted in 27% of the fetal deaths. 70% of the maternal deaths occurred in women aged 20-34. 32 maternal deaths occurred among 16,232 women with 1-2 children, 30 among 6514 women with 3-5 children, and 32 among 5960 women with 6-14 children. 11,027 of the 28,706 were primaparas. Perinatal mortality was 4.46% among primaparas, 8.24% among grand multiparas, and 4.1% among secondiparas. In 58 of the 94 cases of maternal mortality the woman was hospitalized after attempting delivery at home or in a village clinic. Among women with 1 or 2 children, hemorrhage was the cause of death in 8 cases, infection in 7 cases, eclampsia in 3 cases, thromboembolism in 2 cases, uterine inversion in 2 cases, pulmonary tuberculosis in 1 case, embolism in 5 cases, and other causes 1 case each. Among women with 3-5 children hemorrhage was the cause of death in 10 cases, septicemia in 3 cases, uterine rupture in 3 cases, eclampsia in 3 cases, uterine inversion in 2 cases, viral hepatitis in 2 cases, emboli in 2 cases, and other reasons 1 case each. Among grand multiparas hemorrhage was the cause of death in 11 cases, uterine rupture in 12 cases, peritonitis in 2 cases, eclampsia in 2 cases, emboli in 2 cases, and other causes 1 case each. 19 of the maternal deaths were judged to have been avoidable with better management. Prematurity and birth weight of 1000-2500 g associated or not with other pathology were found in 714 of 1546 perinatal deaths. Of 390 cases of death in utero with retention and maceration, 68 were caused by reno-vascular syndromes, 76 by maternal infections, 33 by maternal syphilis, 26 by fetal malformation, 18 by maternal diabetes, 10 by Rh incompatability, and 159 by indeterminate causes.

    Aims To evaluate the associations of myocardial infarction (MI) and major bleeding with 1-year mortality. Both MI and major bleeding predict 1-year mortality in patients presenting with acute coronary syndrome (ACS). However, the risk of each of these events on the magnitude and timing of mortality has not been well studied. Methods and Results A multivariable Cox regression model was developed relating 13 independent baseline predictors to 1-year mortality for 13 819 patients with moderate and high-risk ACS enrolled in the Acute Catheterization and Urgent Intervention Triage strategy trial. After adjustment for baseline predictors, Cox models with major bleeding and recurrent MI as time-updated covariates estimated the effect of these events on mortality hazard over time. Within 30 days of randomization, 705 patients (5.1%) had an MI, 645 (4.7%) had a major bleed; 524 (3.8%) died within a year. The occurrence of an MI was associated with a hazard ratio of 3.1 compared with patients not yet having an MI, after adjustment for baseline predictors. However, MI within 30 days markedly increased the mortality risk for the first 2 days after the event (adjusted hazard ratio of 17.6), but this risk declined rapidly post-infarct (hazard ratio of 1.4 beyond 1 month after the MI event). In contrast, major bleeding had a prolonged association with mortality risk (hazard ratio of 3.5) which remained fairly steady over time throughout 1 year. Conclusion After accounting for baseline predictors of mortality, major bleeds and MI have similar overall strength of association with mortality in the first year after ACS. MI is correlated with a dramatic increase in short-term risk, whereas major bleeding correlates with a more prolonged mortality risk. PMID:19351691

    Aims Multiple trials have shown that implantable cardioverter defibrillators (ICDs) prolong survival in secondary and primary prevention populations. However, in spite of the efficacy of these devices in terminating life-threatening arrhythmias, total mortality remains high. Methods and results We evaluated 1703 patients (mean age: 67 ± 12 years, 82% male) with conventional ICD indications, who were enrolled and followed between 2001 and 2004 at 128 US centres. Patients were followed for up to a year, and vital status was obtained for 1655 patients (97%, median follow-up: 377 days). There were 183 deaths within 1 year of ICD implantation (1-year mortality rate: 16%). Predictors of mortality included a history of atrial fibrillation (AF, P < 0.0001), diabetes (P = 0.0001), failure to use cholesterol-lowering medications (P < 0.001), use of digitalis and derivatives (P < 0.0001), use of diuretics (P < 0.0001), low body mass index (BMI, P < 0.0001), increasing age (P < 0.0001), low left ventricular ejection fraction (P < 0.0001), low activity hours (P < 0.0001), elevated resting heart rate (P = 0.014), low mean arterial pressure (MAP, P = 0.007), and poor functional status (New York Heart Association class, P < 0.0001). In multivariate modelling, AF (P ≤ 0.001), diabetes (P = 0.004), BMI (P = 0.001), MAP (P = 0.040), and functional class (P = 0.006) predicted mortality. Conclusion In this population undergoing ICD implantation, poor functional status, low MAP, diabetes, low BMI, and AF were strongly associated with death within a year. PMID:19279025

    The development of cyclophosphamide-induced pulmonary lesions over a 1-year period was studied in mice. Male BALB/c mice received a single intraperitoneal injection of 100 mg/kg of cyclophosphamide. Within 3 weeks there were scattered foci of intraalveolar foamy macrophages. With time, these foci increased in size and, 1 year later, occupied large areas in all lung lobes. There was also diffuse interstitial fibrosis. Chemical determination done 3, 12, 24, and 52 weeks after cyclophosphamide showed that lungs of animals treated with cyclophosphamide had significantly more hydroxyproline per lung than controls. One year after cyclophosphamide pressure - volume curves measured in vivo were shifted down and to the right and total lung volumes were decreased. A single injection of cyclophosphamide produced an irreversible and progressive pulmonary lesion. 16 references, 5 figures, 3 tables.

    Aims Vitamin K antagonists (VKAs) need to be individually dosed. International guidelines recommend a target range of international normalised ratio (INR) of 2.0–3.0 for stroke prevention in atrial fibrillation (AF). We analysed the time in this therapeutic range (TTR) of VKA-treated patients with newly diagnosed AF in the ongoing, global, observational registry GARFIELD-AF. Taking TTR as a measure of the quality of patient management, we analysed its relationship with 1-year outcomes, including stroke/systemic embolism (SE), major bleeding, and all-cause mortality. Methods and Results TTR was calculated for 9934 patients using 136,082 INR measurements during 1-year follow-up. The mean TTR was 55.0%; values were similar for different VKAs. 5851 (58.9%) patients had TTR<65%; 4083 (41.1%) TTR≥65%. The proportion of patients with TTR≥65% varied from 16.7% in Asia to 49.4% in Europe. There was a 2.6-fold increase in the risk of stroke/SE, 1.5-fold increase in the risk of major bleeding, and 2.4-fold increase in the risk of all-cause mortality with TTR<65% versus ≥65% after adjusting for potential confounders. The population attributable fraction, i.e. the proportion of events attributable to suboptimal anticoagulation among VKA users, was 47.7% for stroke/SE, 16.7% for major bleeding, and 45.4% for all-cause mortality. In patients with TTR<65%, the risk of first stroke/SE was highest in the first 4 months and decreased thereafter (test for trend, p = 0.021). In these patients, the risk of first major bleed declined during follow-up (p = 0.005), whereas in patients with TTR≥65%, the risk increased over time (p = 0.027). Conclusion A large proportion of patients with AF had poor VKA control and these patients had higher risks of stroke/SE, major bleeding, and all-cause mortality. Our data suggest that there is room for improvement of VKA control in routine clinical practice and that this could substantially reduce adverse outcomes. Trial Registration Clinical

    In both animal and epidemiologic studies, exposure to dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin, or TCDD) has been associated with an increased risk of cancer. We conducted a retrospective cohort study of mortality among the 5172 workers at 12 plants in the United States that produced chemicals contaminated with TCDD. Occupational exposure was documented by reviewing job descriptions and by measuring TCDD in serum from a sample of 253 workers. Causes of death were taken from death certificates. Mortality from several cancers previously associated with TCDD (stomach, liver, and nasal cancers, Hodgkin's disease, and non-Hodgkin's lymphoma) was not significantly elevated in this cohort. Mortality from soft-tissue sarcoma was increased, but not significantly (4 deaths; standardized mortality ratio (SMR), 338; 95 percent confidence interval, 92 to 865). In the subcohort of 1520 workers with greater than or equal to 1 year of exposure and greater than or equal to 20 years of latency, however, mortality was significantly increased for soft-tissue sarcoma (3 deaths; SMR, 922; 95 percent confidence interval, 190 to 2695) and for cancers of the respiratory system (SMR, 142; 95 percent confidence interval, 103 to 192). Mortality from all cancers combined was slightly but significantly elevated in the overall cohort (SMR, 115; 95 percent confidence interval, 102 to 130) and was higher in the subcohort with greater than or equal to 1 year of exposure and greater than or equal to 20 years of latency (SMR, 146; 95 percent confidence interval, 121 to 176). This study of mortality among workers with occupational exposure to TCDD does not confirm the high relative risks reported for many cancers in previous studies. Conclusions about an increase in the risk of soft-tissue sarcoma are limited by small numbers and misclassification on death certificates.

    Older adults represent the fastest-growing population of drivers with a valid driver's licence. Also common in this age group are multiple chronic medical conditions that may have an effect on physical function and driving ability. Determining the reliability of physical measures used to assess older drivers' functional ability is important to identifying those who are safe to continue driving. Most previous reliability studies of clinical physical measures of health used test-retest intervals shorter than those between patient visits with a clinician. In the present study we examined a more clinically representative interval of 1 year to determine the stability of commonly used physical measures collected during the Candrive II prospective cohort study of older drivers. Reliability statistics indicate that the sequential finger-thumb opposition, rapid pace walk and the Pelli-Robson contrast sensitivity tests have adequate stability over 1 year. Poor stability was observed for the one-legged stance and Snellen visual acuity test. Several assessments with nominal data (Marottoli method [functional neck range of motion], whispered voice test, range of motion and strength testing) lacked sufficient variability to conduct reliability analyses; however, a lack of variability between test days suggests consistency over a 1-year time frame. Our results provide evidence that specific physical measures are stable in monitoring functional ability over the course of a year.

    Many insurers offer life coverage to individuals during the first year of life. The policies tend to have small face values, but frequently contain premium waiver or additional purchase options. General population mortality is significantly higher at this age relative to older children and even middle-aged adults. This article presents the mortality experience of an insured cohort in which death occurred under 1 year of age. In summary, the insured population's mortality rate was significantly lower and the leading causes of death were different than the general population.

    We describe management and outcomes of patients with nonvalvular atrial fibrillation (AF) in the Middle East. Consecutive patients with AF presenting to emergency departments (EDs) were prospectively enrolled. Among 1721 patients with nonvalvular AF, mean age was 59 ± 16 years and 44% were women. Comorbidities were common such as hypertension (59%), diabetes (33%), and coronary artery disease (33%). Warfarin was not prescribed to 40% of patients with Congestive heart failure, Hypertension, Age, Diabetes mellitus, Stroke/TIA2 score of ≥2. One-year rates of stroke/transient ischemic attack (TIA) and all-cause mortality were 4.2% and 15.3%, respectively. Warfarin use at hospital-ED discharge was independently associated with lower 1-year rate of stroke/TIA (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.17-0.85; P = .015) and all-cause mortality (OR, 0.51; 95% CI, 0.32-0.83; P = .006). Prior history of heart failure and peripheral vascular disease was independent mortality predictors. Our patients are relatively young with significant cardiovascular risk. Their anticoagulation treatment is suboptimal, and 1-year all-cause mortality and stroke/TIA event rates are relatively high.

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

    Background: Regarding failure to establish the statistical presuppositions for analysis of the data by conventional approaches, hierarchical structure of the data as well as the effect of higher-level variables, this study was conducted to determine the factors independently associated with hospital mortality due to myocardial infarction (MI) in Iran using a multilevel analysis. Methods: This study was a national, hospital-based, and cross-sectional study. In this study, the data of 20750 new MI patients between April, 2012 and March, 2013 in Iran were used. The hospital mortality due to MI was considered as the dependent variable. The demographic data, clinical and behavioral risk factors at the individual level and environmental data were gathered. Multilevel logistic regression models with Stata software were used to analyze the data. Results: Within 1-year of study, the frequency (%) of hospital mortality within 30 days of admission was derived 2511 (12.1%) patients. The adjusted odds ratio (OR) of mortality with (95% confidence interval [CI]) was derived 2.07 (95% CI: 1.5–2.8) for right bundle branch block, 1.5 (95% CI: 1.3–1.7) for ST-segment elevation MI, 1.3 (95% CI: 1.1–1.4) for female gender, and 1.2 (95% CI: 1.1–1.3) for humidity, all of which were considered as risk factors of mortality. But, OR of mortality was 0.7 for precipitation (95% CI: 0.7–0.8) and 0.5 for angioplasty (95% CI: 0.4–0.6) were considered as protective factors of mortality. Conclusions: Individual risk factors had independent effects on the hospital mortality due to MI. Variables in the province level had no significant effect on the outcome of MI. Increasing access and quality to treatment could reduce the mortality due to MI. PMID:26730342

    Objectives Hematuria is considered a marker of active renal disease in ANCA-associated glomerulonephritis (ANCA-GN) with induction immunosuppression often continued until hematuria has resolved. We aim to determine whether longer hematuria duration is associated with lower estimated glomerular filtration rate (eGFR) at 1 year. Methods We conducted a retrospective study of 55 patients with biopsy-proven ANCA-GN. Linear regression models were constructed to determine predictors of eGFR at 1 year. The primary exposure was hematuria (>5 rbc/hpf) duration, defined as <90 days vs. ≥90 days following renal biopsy. Covariates included age, gender, ANCA type, baseline eGFR, and baseline proteinuria. Results Mean age at diagnosis was 58 years (53% male, 80% Caucasian, 38% PR3-ANCA, and 45% MPO-ANCA). At baseline, all patients had hematuria, 95% had proteinuria, and mean serum creatinine was 3.1 [standard deviation (SD) = 2.3] mg/dL. Overall, 93% were treated with steroids in combination with either cyclophosphamide or rituximab. Mean hematuria duration was 92 (SD = 77) days with 34 (62%) patients having hematuria resolution within 90 days. Older age and lower baseline eGFR were associated with lower eGFR at 1 year (p = 0.03 and p < 0.001, respectively). Hematuria resolution (<90 days vs. ≥90 days) was not predictive of eGFR at 1 year (p = 0.93). Conclusions In ANCA-GN, hematuria duration does not predict eGFR at 1 year. Our findings provide support that among individuals who are otherwise considered to be in clinical remission, the persistence of hematuria should not delay transition from induction to maintenance immunosuppression.

    Objective Hypomagnesemia has been associated with an increase in mortality among the general population as well as patients with chronic kidney disease or those on hemodialysis. However, this association has not been thoroughly studied in patients undergoing peritoneal dialysis. The aim of this study was to evaluate the association between serum magnesium concentrations and all-cause and cardiovascular mortalities in peritoneal dialysis patients. Methods This single-center retrospective study included 253 incident peritoneal dialysis patients enrolled between July 1, 2005 and December 31, 2014 and followed to June 30, 2015. Patient’s demographic characteristics as well as clinical and laboratory measurements were collected. Results Of 253 patients evaluated, 36 patients (14.2%) suffered from hypomagnesemia. During a median follow-up of 29 months (range: 4–120 months), 60 patients (23.7%) died, and 35 (58.3%) of these deaths were attributed to cardiovascular causes. Low serum magnesium was positively associated with peritoneal dialysis duration (r = 0.303, p < 0.001) as well as serum concentrations of albumin (r = 0.220, p < 0.001), triglycerides (r = 0.160, p = 0.011), potassium (r = 0.156, p = 0.013), calcium(r = 0.299, p < 0.001)and phosphate (r = 0.191, p = 0.002). Patients in the hypomagnesemia group had a lower survival rate than those in the normal magnesium groups (p < 0.001). In a multivariate Cox proportional hazards regression analysis, serum magnesium was an independent negative predictor of all-cause mortality (hazard ratio [HR] = 0.075, p = 0.011) and cardiovascular mortality (HR = 0.003, p < 0.001), especially in female patients. However, in univariate and multivariate Cox analysis, △Mg(difference between 1-year magnesium and baseline magnesium) was not an independent predictor of all-cause mortality and cardiovascular mortality. Conclusion Hypomagnesemia was common among peritoneal dialysis patients and was independently associated with all

    A national sample of 1500 mothers of 1-year-old children received a postal questionnaire concerned with the sleeping patterns of their children. The response rate was 69%. Seventeen per cent of mothers reported that their 1-year-old presented a moderate or severe sleep problem and 26% said their child woke at night on at least five nights a week. While these two measures correlated, 10% of those who reported their infant woke on at least five nights a week did not consider this to be a problem. Neither sex of infant, social class, method of infant feeding or numbers of house moves were associated with sleep problems. The pattern of results strongly suggest an association between night waking and other sleeping difficulties and stress for mothers. This was indicated by the association we found with complaints about housing, overcrowding, more negative attitudes toward motherhood, lower assessments of maternal well-being, lack of practical support from partners, the use of more negative adjectives to describe their baby and more frequent feelings of being dominated by their baby. While these associations may be explained by the stresses of living with a night-waking baby, it is also likely that a mother who is feeling somewhat depressed and negative toward her baby is more likely to see night waking as significant and as a problem. There were class differences in how parents coped with a shortage of space. Middle-class parents were more likely to put a baby in with a sibling while working class parents more often had the baby in their own room. Middle-class parents were more likely to leave a night-waking baby to cry. PMID:2225345

    Pueraria mirifica is a tuberous plant enriched with active phytoestrogens. There is no established information about the factors influencing isoflavonoid storage in the tubers. We investigated the tuberous storage of the major isoflavonoids of 1-year-old plants. Four cultivars of P. mirifica were cultivated in the same field trial during the same period to establish a unique plant age and differentiation under the same environment and soil conditions. The tubers collected from the 1-year-old plants in the summer, rainy season and winter were submitted to an HPLC analysis with a gradient system comprising 0.1% acetic acid and acetonitrile. Five major isoflavonoids, puerarin, daidzin, genistin, daidzein and genistein, were adopted as standards. P. mirifica tubers of different cultivars collected in the same season exhibited significant differences in individual and total isoflavonoid contents, showing chemovariety. P. mirifica tubers of the same cultivar collected from different seasons also exhibited significant differences in individual and total isoflavonoid contents, showing the influence of season. In conclusion, the tuberous storage of major isoflavonoids in 1-year-cultivated plants was greatly diverse and was strongly influenced by the season and plant genetics.

  19. Predictors of Relapse after Inpatient Opioid Detoxification during 1-Year Follow-Up

    2016-01-01

    Introduction. Relapse rate after opioid detoxification is very high. We studied the possibility that predetoxification patient characteristics might predict relapse at follow-up and thus conducted this 1-year follow-up study to assess the predictors of relapse after inpatient opioid detoxification. Materials and Methods. We conducted this study in our tertiary care institute in India over two-year time period (1 Jan 2014 to 31 Dec 2015). Out of 581 patients admitted, 466 patients were considered for study. Results and Discussion. No significant difference was found between relapsed and nonrelapsed patients regarding sociodemographic profile; however substance abuse pattern and forensic history showed significant differences. Relapsed patients abused greater amount and used injections more commonly, as compared to nonrelapsed group. Longer duration of abuse was also a significant risk factor. Patients with past attempt of opioid detoxification and family history (parental or first degree) of alcohol abuse had decreased possibility of maintaining remission during 1-year follow-up. Relapsed patients were found to abuse their spouse or parents. Conclusion. Our study compared profiles of relapsed and nonrelapsed patients after inpatient detoxification and concluded predictors of relapse during 1-year follow-up period. Early identification of predictors of relapse and hence high risk patients might be helpful in designing more effective and focused treatment plan. PMID:27722007

    Introduction This prospective observational study evaluated changes in the 3-dimensional position and remodeling of the mandibular rami, condyles, and chin at splint removal and 1 year after mandibular advancement surgery. Methods Presurgery, splint removal (4–6 weeks postsurgery), and 1-year postsurgery cone-beam computed tomography scans of 27 subjects were used. Superimposition on the cranial base was used to assess positional or remodeling changes in the anatomic regions of interest. Surface distance displacements were visually displayed and quantified by 3-dimensional color maps. A 1-sample t test was used to assess the average postsurgical changes of each region of interest. The level of significance was set at 0.05. Results After antero-inferior chin displacement with surgery (mean, 6.81 ± 3.2 mm at splint removal), the average 1-year post-surgery displacement was not statistically significant (P = 0.44). Postsurgical adaptations greater than 2 mm were observed in 48% of the patients: 16% with an additional anterior-inferior displacement of the chin of 2 to 4 mm, and 4% with ≥4 mm; 20% had postero-superior movement of 2 to 4 mm, and 8% had postero-superior movement of ≥4 mm. The condyles tended to move, on average, ≤2 mm supero-posteriorly with surgery, and this small positional displacement was maintained 1 year postsurgery (right condyle, P = 0.58; left, P = 0.88). The rami exhibited outward (lateral) movements with surgery, with greater displacement of the inferior part of the rami (≥2 mm in 65% of the subjects). This torque of the ramus with surgery was stable 1 year postsurgery. Conclusions Three-dimensional assessment of skeletal changes with mandibular advancement surgery shows that nearly half of the patients have >2 mm change in chin position from splint removal to the 1-year follow-up, with approximately equal chances of anterior and posterior movement. Torque of the rami usually occurs with mandibular advancement surgery. PMID:20381760

    Three studies provide data on this topic. The largest was at the Ferodo factory in the U.K. There was no evidence of an overall excess in mortality from all causes, and in particular no increase in mortality due to lung cancer. Also, there was no evidence of any dose-response effect for lung cancer. There were 13 mesotheliomas but for 10 of these there had been exposure to crocidolite whilst working on a special contract that only a small minority of the workforce were involved in. Another one had worked in an asbestos-cement factory for 20 years. This left two mesotheliomas, one unconfirmed, for which the only known exposure was to chrysotile asbestos. The second study was of a plant in Connecticut. There was a significant increase in mortality due to respiratory cancer, but this excess was greatest in those with less than 1 year's exposure and was unrelated to cumulative exposure. No mesotheliomas occurred. The third study was of two factories in Ontario manufacturing automotive components. There was a non-significant increase in lung cancer mortality but the majority of these had not worked in the departments where asbestos was used. There were two unconfirmed mesotheliomas, one of whom had worked with friction materials. In conclusion, the three studies show that, if there are any effects on mortality due to working in the manufacture of friction materials, these effects must be small.

    OBJECTIVE: We aimed to measure the mortality rate and excess general mortality as well as identify groups at high risk for mortality among a cohort of tuberculosis patients treated in Chennai Corporation clinics in south India. METHODS: In this retrospective cohort study we followed up 2674 patients (1800 males and 874 females) who were registered and treated under the DOTS strategy in Chennai Corporation clinics in 2000. The follow-up period from the date of start of treatment to either the date of interview, or death was 600 days. FINDINGS: The mortality rate among this cohort of tuberculosis patients was 60/1000 person-years. The excess general mortality expressed as standardized mortality ratio (SMR) was 6.1 (95% confidence interval (CI)=5.4-6.9). Younger patients, men, patients with Category II disease, patients who defaulted on, or failed courses of treatment, and male smokers who were alcoholics, all had higher mortality ratios when compared to the rest of the cohort. CONCLUSION: The excess mortality in this cohort was six times more than that in the general population. Young age, male sex, smear-positivity, treatment default, treatment failure and the combination of smoking and alcoholism were identified as risk factors for tuberculosis mortality. We suggest that mortality rate and excess mortality be routinely used as a monitoring tool for evaluating the efficiency of the national control programme. PMID:16878229

    Objective To measure the 1-year incidence of fibromyalgia in a cohort of acute whiplash-injured participants. Methods Consecutive acute patients with whiplash were assessed via the 2010 Modified American College of Rheumatology (ACR) criteria for fibromyalgia at 3 months, 6 months and 1 year postinjury. At each of these follow-up points, participants were also examined for recovery from whiplash injury. Results Of an initial 268 participants, data on recovery was available for 264 participants during the 1-year follow-up period. At the 3-month follow-up, 62% (167/268) of participants reported recovery from their whiplash injuries. At 6 months, 76% (203/268) reported recovery, and at 1 year 82% (216/264) reported recovery. At 3 and 6 months follow-up none of the participants met the 2010 Modified ACR Criteria for fibromyalgia, but fibromyalgia criteria were met for 2 (of 264) seen at the 1-year follow-up, yielding a 1-year incidence of 0.8% (95% CI 0.1% to 3.0%). Conclusions In the primary care setting, a significant proportion of patients with whiplash recover from whiplash injury at 1 year, and the incidence of fibromyalgia after acute whiplash injury is very low. The impression that fibromyalgia is common after whiplash injury may be due to the failure to exclude precollision fibromyalgia cases or due to referral bias of non-recovered patients. PMID:26509044

    OBJECTIVES To determine whether circadian activity rhythms are associated with mortality in community-dwelling older women. DESIGN Prospective study of mortality. SETTING A cohort study of health and aging. PARTICIPANTS 3,027 community-dwelling women from the Study of Osteoporotic Fractures cohort (mean age 84 years). MEASUREMENTS Activity data were collected with wrist actigraphy for a minimum of three 24-hour periods and circadian activity rhythms were computed. Parameters of interest included height of activity peak (amplitude), mean activity level (mesor), strength of activity rhythm (robustness), and time of peak activity (acrophase). Vital status, with cause of death adjudicated through death certificates, was prospectively ascertained. RESULTS Over an average of 4.1 years of follow-up there were 444 (15%) deaths. There was an inverse association between peak activity height and all-cause mortality rates with higher mortality rates observed in the lowest activity quartile (Hazard ratio [HR]=2.18, 95% CI, 1.63–2.92) compared with the highest quartile after adjusting for age, clinic site, race, BMI, cognitive function, exercise, IADL impairments, depression, medications, alcohol, smoking, self-reported health status, married status, and co-morbidities. Increased risk of all-cause mortality was observed between lower mean activity level (HR=1.71, 95% CI, 1.29–2.27) and rhythm robustness (HR=1.97, 95% CI, 1.50–2.60). Increased mortality from cancer (HR=2.09, 95% CI, 1.04–4.22) and stroke (HR=2.64, 95% CI, 1.11–6.30) was observed for a delayed timing of peak activity (after 4:33PM; >1.5 SD from mean) when compared to the mean peak range (2:50PM–4:33PM). CONCLUSION Older women with weak circadian activity rhythms have higher mortality risk. If confirmed in other cohorts, studies will be needed to test whether interventions (e.g. physical activity, bright light exposure) that regulate circadian activity rhythms will improve health outcomes in the elderly

    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.

  6. Strategies to reduce neonatal mortality.

    Singh, M

    In India, 60% of deaths in infants under 1 year of age occur in the 1st 4 weeks after birth. The neonatal mortality rate is currently 76/1000 live births in rural areas and 39/1000 in urban areas. The Government if India has launched a plan of action of address the cycle of poorly spaced pregnancies, inadequate maternal health care and nutrition, and high incidence of low birthweight babies that contributes to this high neonatal mortality phenomenon. Crucial to such a plan is the expansion, strengthening, and improved organization of maternal-child health services. At the level of maternal health services, efforts will be made to identify pregnant women early, arrange a minimum of 4 prenatal visits, provide dietary supplementation and immunization against tetanus toxoid, create more sterile conditions for home deliveries, identify and refer high-risk pregnancies and deliveries, and provide postnatal follow-up care. Child health service staff are motivating mothers to breastfeed and screening newborns for jaundice and bacterial infection. A risk approach, in which there is a minimum necessary level of care for all pregnant women but more intensive management and follow-up of those at high risk, is most cost-efficient given the lack of human and financial resources. Attention must also be given to the determinants of low birthweight (maternal undernutrition, closely spaced pregnancies, severe anemia, adolescent childbearing, prenatal infections, strenuous work responsibilities, and maternal hypertension), which is a co-factor in neonatal mortality.

    Clinical depression is associated with social, occupational and physical impairment and mortality. Furthermore, data are reviewed which have related the severity of depressive symptoms, such as anhedonia, psychic anxiety, panic attacks, alcohol abuse, insomnia and diminished concentration in depressed patients, to suicide within 1 year. By contrast, hopelessness, suicidal ideation, and prior suicide attempts were related to suicide within 2-10 years after examination, but did not correlate with suicide within the first year of follow-up. It is concluded that clinical depression continues to be associated with significant morbidity and mortality, despite progress which has been made in its treatment. PMID:8277138

    Objective Depression is an independent predictor of adverse outcomes in patients with heart failure (HF). However, the effect of changes in cognitive-affective and somatic symptoms on mortality of HF patients is not known. The purpose of this study was to examine whether changes in cognitive-affective and somatic depressive symptoms over time were associated with mortality in HF. Methods In this secondary analysis of data from the REMOTE-HF clinical trial, we analyzed data from 457 HF patients (39% female, mean [SD] age, 65.6 [12.8] years) who survived at least 1 year and repeated the Patient Health Questionnaire (PHQ-9) at 1 year. Cognitive-affective and somatic depression scores were calculated, respectively, based on published PHQ-9 factor models. Using Cox proportional-hazards regression analyses, we evaluated the effect of changes in cognitive-affective and somatic symptoms from baseline to 1 year on cardiac and all-cause deaths. Results Controlling for baseline depression scores and other patient characteristics, the change in somatic symptoms was associated with increased risk of cardiac death during the subsequent 1-year period (hazard ratio [HR] = 1.24, 95% confidence interval [CI]: 1.07 – 1.44, p = .005), but the change in cognitive-affective symptoms was not (HR = 0.94, 95% CI: 0.81 – 1.08, p = .38). Similar results were found for all-cause mortality. Conclusions Worsening somatic depressive symptoms, not cognitive-affective symptoms, are independently associated with increased mortality of HF patients. The findings suggest that routine and ongoing assessment of somatic depressive symptoms in HF patients may help clinicians identify patients at increased risk for adverse outcomes. PMID:26230482

    Purpose Vertebroplasty is an effective treatment for painful compression fractures refractory to conservative management. Since there are limited data regarding the survival characteristics of this patient population, we compared the survival of a treated to an untreated vertebral fracture cohort to determine if vertebroplasty affects mortality rates. Materials and Methods The survival of a treated cohort, comprising 524 vertebroplasty recipients with refractory osteoporotic vertebral compression fractures, was compared to a separate, historical cohort of 589 subjects with fractures not treated by vertebroplasty who were identified from the Rochester Epidemiology Project. Mortality was compared between cohorts using Cox proportional hazard models adjusting for age, gender, and Charlson indices of co-morbidity. Mortality was also correlated with pre-, peri-, and post-procedural clinical metrics (e.g., cement volume utilization, Roland-Morris Disability Questionnaire score, analog pain scales, frequency of narcotic use, and improvements in mobility) within the treated cohort. Results Vertebroplasty recipients demonstrated 77% of the survival expected for individuals of similar age, ethnicity, and gender within the US population. When compared to individuals with both symptomatic and asymptomatic untreated vertebral fractures, vertebroplasty recipients retained a 17% greater mortality risk. However, when compared to symptomatic untreated vertebral fractures, vertebroplasty recipients had no increased mortality following adjustment for differences in age, sex and co-morbidity (HR 1.02; CI 0.82–1.25). In addition, no clinical metrics used to assess the efficacy of vertebroplasty were predictive of survival. Conclusion Vertebroplasty recipients have mortality rates similar to individuals with untreated symptomatic fractures but worse mortality compared to those with asymptomatic vertebral fractures.

    OBJECTIVE--To assess effect of unemployment and early retirement on mortality in a group of middle aged British men. DESIGN--Prospective cohort study (British Regional Heart Study). Five years after initial screening, information on employment experience was obtained with a postal questionnaire. SETTING--One general practice in each of 24 towns in Britain. SUBJECTS--6191 men aged 40-59 who had been continuously employed for at least five years before initial screening in 1978-80: 1779 experienced some unemployment or retired during the five years after screening, and 4412 remained continuously employed. MAIN OUTCOME MEASURE--Mortality during 5.5 years after postal questionnaire. RESULTS--Men who experienced unemployment in the five years after initial screening were twice as likely to die during the following 5.5 years as men who remained continuously employed (relative risk 2.13 (95% confidence interval 1.71 to 2.65). After adjustment for socioeconomic variables (town and social class), health related behaviour (smoking, alcohol consumption, and body weight), and health indicators (recall of doctor diagnoses) that had been assessed at initial screening the relative risk was slightly reduced, to 1.95 (1.57 to 2.43). Even men who retired early for reasons other than illness and who appeared to be relatively advantaged and healthy had a significantly increased risk of mortality compared with men who remained continuously employed (relative risk 1.87 (1.35 to 2.60)). The increased risk of mortality from cancer was similar to that of mortality from cardiovascular disease (adjusted relative risk 2.07 and 2.13 respectively). CONCLUSIONS--In this group of stably employed middle aged men loss of employment was associated with an increased risk of mortality even after adjustment for background variables, suggesting a causal effect. The effect was non-specific, however, with the increased mortality involving both cancer and cardiovascular disease. PMID:8173455

    Background and Aims Liver transplantation is the only curative treatment for end-stage liver disease. While waiting list mortality can be predicted by the MELD-score, reliable scoring systems for the postoperative period do not exist. This study's objective was to identify risk factors that contribute to postoperative mortality. Methods Between December 2006 and March 2011, 429 patients underwent liver transplantation in our department. Risk factors for postoperative mortality in 266 consecutive liver transplantations were identified using univariate and multivariate analyses. Patients who were <18 years, HU-listings, and split-, living related, combined or re-transplantations were excluded from the analysis. The correlation between number of risk factors and mortality was analyzed. Results A labMELD ≥20, female sex, coronary heart disease, donor risk index >1.5 and donor Na+>145 mmol/L were identified to be independent predictive factors for postoperative mortality. With increasing number of these risk-factors, postoperative 90-day and 1-year mortality increased (0–1: 0 and 0%; 2: 2.9 and 17.4%; 3: 5.6 and 16.8%; 4: 22.2 and 33.3%; 5–6: 60.9 and 66.2%). Conclusions In this analysis, a simple score was derived that adequately identified patients at risk after liver transplantation. Opening a discussion on the inclusion of these parameters in the process of organ allocation may be a worthwhile venture. PMID:24905210

    Background and Objectives Temporal trends in mortality from congenital heart disease (CHD) vary among regions. It is therefore necessary to study this problem in each country. In Mexico, congenital anomalies were responsible for 24% of infant mortality in 2013 and CHD represented 55% of total deaths from congenital anomalies among children under 1 year of age. The objectives of this study were to analyze the trends in infant mortality from CHD in Mexico (1998 to 2013), its specific causes, age at death and associated socio-demographic factors. Methods Population-based study which calculated the compounded annual growth rate of death rom CHD between 1998 and 2013. Specific causes, age at which death from CHD occurred and risk factors associated with mortality were analyzed for the year 2013. Results Infant mortality from CHD increased 24.8% from 1998 to 2013 (114.4 to 146.4/ 100,000 live births). A total of 3,593 CHD deaths occurred in 2013; the main causes were CHD with left-to-right shunt (n = 487; 19.8/100,000 live births) and cyanotic heart disease (n = 410; 16.7/100,000). A total of 1,049 (29.2%) deaths from CHD occurred during the first week of life. Risk factors associated with mortality from CHD were, in order of magnitude: non-institutional birth, rural area, birth in a public hospital and male sex. Conclusions Mortality from CHD has increased in Mexico. The main causes were CHD with left-to-right shunt, which are not necessarily fatal if treated promptly. Populations vulnerable to death from CHD were identified. Approximately one-third of the CHD occurred during the first week of life. It is important to promote early diagnosis, especially for non-institutional births. PMID:26937635

    Outcome data from large series confirm increased mortality of patients with pituitary tumours, predominantly due to vascular disease. Control of cortisol secretion and growth hormone (GH) hypersecretion (together with cardiovascular risk factor reduction) is key in the normalisation of mortality rates in patients with Cushing's disease and acromegaly, respectively, though some excess mortality may persist even in "cured" patients.

    Aim and Design: A retrospective, nonrandomized, single-center clinical study was designed to evaluate the outcomes of corneal collagen crosslinking (CXL) for progressive keratoconus in Iranian patients 12 months after CXL. Settings: This study was carried out at Navid Didegan Eye Center, a private clinic, Mashhad, Iran. Materials and Methods: Ninety-two eyes of 53 subjects with progressive keratoconus were evaluated in this study. All eyes completed 1-year follow-up. The outcome measures were uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), sphere and cylinder refraction, keratometry, and corneal thickness. Comparison of baseline and 1-year postoperative data is reported in this study. The Wilcoxon signed-ranked and Student’s t-tests were used for statistical analyses. P < 0.05 was statistically significant. Results: The mean age was 21.5 ± 3.4 years (range, 16 -30 years). Thirty-one (58.5%) of the subjects were men and 22 (41.5%) were women. Mean baseline UCVA and BSCVA were 0.61 ± 0.31 and 0.06 ± 0.12 logarithm of minimal angle of resolution (logMAR), respectively. One year postoperatively UCVA was 0.31 ± 0.25 logMAR and BSCVA was 0.0 ± 0.01 logMAR. UCVA and BSCVA were statistically higher postoperatively (P < 0.001, both parameters). The mean astigmatism decreased by 0.78 ± 1.49 diopter (D) with significant variation during the follow-up period (P < 0.001). Mean baseline simulated keratometry (SIM K) was 46.94 ± 2.37 D and decreased to 46.0 ± 2.33 D on year postoperatively (P < 0.001). Conclusion: Corneal CXL seems to be efficient in stabilization of progressive keratoconus progression in Iranian patients at 1 year of followup. PMID:21180440

    Objective To evaluate the effectiveness of a worksite health promotion program on improving cardiovascular disease risk factors. Methods In St Louis, Missouri from 2005 to 2006, 151 employees (134 F, 17 M, 81% overweight/obese) participated in a cohort-randomized trial comparing assessments + intervention (worksite A) with assessments only (worksite B) for 1 year. All participants received personal health reports containing their assessment results. The intervention was designed to promote physical activity and favorable dietary patterns using pedometers, healthy snack cart, WeightWatchers® meetings, group exercise classes, seminars, team competitions, and participation rewards. Outcomes included BMI, body composition, blood pressure, fitness, lipids, and Framingham 10-year coronary heart disease risk. Results 123 participants, aged 45 ± 9 yr, with BMI 32.9 ± 8.8 kg/m2 completed 1 year. Improvements (P ≤ 0.05) were observed at both worksites for fitness, blood pressure, and total-, HDL-, and LDL-cholesterol. Additional improvements occurred at worksite A in BMI, fat mass, Framingham risk score, and prevalence of the metabolic syndrome; only the changes in BMI and fat mass were different between worksites. Conclusion A multi-faceted worksite intervention promoted favorable changes in cardiovascular disease risk factors, but many of the improvements were achieved with worksite health assessments and personalized health reports in the absence of an intervention.

    The Hanford data set has attracted attention primarily because of analyses conducted by Mancuso, Stewart, and Kneale (MSK). These investigators claim that the Hanford data provide evidence that our current estimates of cancer mortality resulting from radiation exposure are too low, and advocate replacing estimates based on populations exposed at relatively high doses (such as the Japanese atom bomb survivors) with estimates based on the Hanford data. In this paper, it is shown that the only evidence of association of radiation exposure and mortality provided by the Hanford data is a small excess of multiple myeloma, and that this data set is not adequate for reliable risk estimation. It is demonstrated that confidence limits for risk estimates are very wide, and that the data are not adequate to differentiate among models. The more recent MSK analyses, which claim to provide adequate models and risk estimates, are critiqued. 18 references, 1 table.

    Objectives: This study was done to determine the effect of malnutrition on mortality in Pediatric Intensive Care Unit (PICU) and on the pediatric risk of mortality (PRISM) scoring. Subjects and Methods: This was a prospective study done over 1 year. There were total 400 patients (1 month 14 years), who were divided into cases with weight for age <3rd centile and controls with ≥3rd centile of WHO charts. Cases were subdivided into mild/moderate (61–80% of expected weight for age) and severe malnutrition (<60%). Results: Out of total, 38.5% patients were underweight, and malnutrition was more in infancy, 61/104, i.e. 58.5% (P - 0.003). There was no significant difference in vitals at admission. Cases needed prolonged mechanical ventilation (P - 0.0063) and hospital stay (P - 0.0332) compared to controls. Mean and median PRISM scores were comparable in both the groups, but mortality was significantly higher in severely malnourished (P value 0.027). Conclusion: Severe malnutrition is independently associated with higher mortality even with similar PRISM score. There is need to give an additional score to children with weight for age <60% of expected. PMID:27555691

    Background and Objective Twenty per cent of chronic obstructive pulmonary disease (COPD) patients are readmitted for acute exacerbation (AECOPD) within 30 days of discharge. The prognostic significance of early readmission is not fully understood. The objective of our study was to estimate the mortality risk associated with readmission for acute exacerbation within 30 days of discharge in COPD patients. Methods The cohort (n = 378) was divided into patients readmitted (n = 68) and not readmitted (n = 310) within 30 days of discharge. Clinical, laboratory, microbiological, and severity data were evaluated at admission and during hospital stay, and mortality data were recorded at four time points during follow-up: 30 days, 6 months, 1 year and 3 years. Results Patients readmitted within 30 days had poorer lung function, worse dyspnea perception and higher clinical severity. Two or more prior AECOPD (HR, 2.47; 95% CI, 1.51–4.05) was the only variable independently associated with 30-day readmission. The mortality risk during the follow-up period showed a progressive increase in patients readmitted within 30 days in comparison to patients not readmitted; moreover, 30-day readmission was an independent risk factor for mortality at 1 year (HR, 2.48; 95% CI, 1.10–5.59). In patients readmitted within 30 days, the estimated absolute increase in the mortality risk was 4% at 30 days (number needed to harm NNH, 25), 17% at 6-months (NNH, 6), 19% at 1-year (NNH, 6) and 24% at 3 years (NNH, 5). Conclusion In conclusion a readmission for AECOPD within 30 days is associated with a progressive increased long-term risk of death. PMID:26943928

  5. [Marginality and infant mortality].

    PubMed

    Jimenez Ornelas, R

    1988-01-01

    This study is concerned with differentials in infant and child mortality among low-income urban groups in Mexico. Mortality differentials within and among marginal socioeconomic groups in suburbs of Mexico City and Leon are analyzed and compared using data collected in interviews in 1980 and 1983. The results indicate that the health benefits associated with modernization, such as improved sanitation, can sometimes be offset by their negative impact on mortality, such as industrial accidents and environmental pollution.

    Purpose Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality worldwide. Incidence rates are increasing in the United States. Monitoring incidence, survival, and mortality rates within at-risk populations can facilitate control efforts. Methods Age-adjusted incidence trends for HCC were examined in the Surveillance, Epidemiology, and End Results (SEER) registries from 1975 to 2005. Age-specific rates were examined for birth cohorts born between 1900 and 1959. Age-adjusted incidence and cause-specific survival rates from 1992 to 2005 were examined in the SEER 13 registries by race/ethnicity, stage, and treatment. United States liver cancer mortality rates were also examined. Results Age-adjusted HCC incidence rates tripled between 1975 and 2005. Incidence rates increased in each 10-year birth cohort from 1900 through the 1950s. Asians/Pacific Islanders had higher incidence and mortality rates than other racial/ethnic groups, but experienced a significant decrease in mortality rates over time. From 2000 to 2005, marked increases in incidence rates occurred among Hispanic, black, and white middle-aged men. Between 1992 and 2004, 2- to 4-year HCC survival rates doubled, as more patients were diagnosed with localized and regional HCC and prognosis improved, particularly for patients with reported treatment. Recent 1-year survival rates remained, however, less than 50%. Conclusion HCC incidence and mortality rates continue to increase, particularly among middle-aged black, Hispanic, and white men. Screening of at-risk groups and treatment of localized-stage tumors may contribute to increasing HCC survival rates in the United States. More progress is needed. PMID:19224838

    Hemorrhage remains as one of the top 3 obstetrics related causes of maternal mortality, with most deaths occurring within 24-48 hours of delivery. Although hemorrhage related maternal mortality has declined globally, it continues to be a vexing problem. More specifically, the developing world continue to shoulder a disproportionate share of hemorrhage related deaths (99%) compared with industrialized nations (1%). Given the often preventable nature of death from hemorrhage, the cornerstone of effective mortality reduction involves risk factor identification, quick diagnosis, and timely management. In this monograph we will review the epidemiology, etiology, and preventative measures related to maternal mortality from hemorrhage.

  8. Predictors of Morbidity and Mortality in Organophosphorus Poisoning: A Case Study in Rural Hospital in Karnataka, India

    2015-01-01

    Background: Organophosphorus (OP) pesticides poisoning can result from occupational, accidental or intentional exposure. Clinical manifestations include cholinergic syndromes, central nervous (CNS) system and cardiovascular disorders. Death is usually due to cardiovascular and respiratory failure. Aim: To evaluate various parameters that can predict outcome of patients in OP poisoning. Materials and Methods: A prospective study conducted in Department of Medicine, Adichunchingiri Institute Of medical Sciences and Research Centre, Karnataka, over period of 1 year. Diagnosis of OP poisoning was based on clinical history of exposure to OP compound and low serum pseudocholinesterase levels. Results: In the present study 133 patients were enrolled, out of which 98.5% were suicidal cases and only 1.5% had accidental exposure. Majority of cases were young male, with F/M ratio 1:3.2. Mortality rates were higher in younger people and in patients who required prolonged ventilator support. The mortality rate was directly proportional to amount of poison consumed, lag time, organ failure (Acute Renal Failure) and plasma pseudocholinesterase levels. Acute complications were frequently noted and were related to morbidity and mortality. No strict relationship was found between liver dysfunction, electrolyte disturbance and clinical outcome. Conclusion: This case study concluded that mortality is directly proportionate to the lag time, amount of OP substances consumed, clinical severity, pseudocholinesterase levels, Acute renal failure and duration of ventilatory support. This study highlights the importance of rapid diagnosis, and initiation of early and effective treatment, which may result in less number complications and also decreases the mortality rates.

    Background. While cardiovascular events remain the primary form of mortality in haemodialysis (HD) patients, few centres are aware of the impact of the hydration status (HS). The aim of this study was to investigate how the magnitude of the prevailing overhydration influences long-term survival. Methods. We measured the hydration status in 269 prevalent HD patients (28% diabetics, dialysis vintage = 41.2 ± 70 months) in three European centres with a body composition monitor (BCM) that enables quantitative assessment of hydration status and body composition. The survival of these patients was ascertained after a follow-up period of 3.5 years. The cut off threshold for the definition of hyperhydration was set to 15% relative to the extracellular water (ECW), which represents an excess of ECW of ∼2.5 l. Cox-proportional hazard models were used to compare survival according to the baseline hydration status for a set of demographic data, comorbid conditions and other predictors. Results. The median hydration state (HS) before the HD treatment (ΔHSpre) for all patients was 8.6 ± 8.9%. The unadjusted gross annual mortality of all patients was 8.5%. The hyperhydrated subgroup (n = 58) presented ΔHSpre = 19.9 ± 5.3% and a gross mortality of 14.7%. The Cox adjusted hazard ratios (HRs) revealed that age (HRage = 1.05, 1/year; P < 0.001), systolic blood pressure (BPsys) (HRBPsys = 0.986 1/mmHg; P = 0.014), diabetes (HRDia = 2.766; P < 0.001), peripheral vascular disease (PVD) (HRPVD = 1.68; P = 0.045) and relative hydration status (ΔHSpre) (HRΔHSpre = 2.102 P = 0.003) were the only significant predictors of mortality in our patient population. Conclusion. The results of our study indicate that the hydration state is an important and independent predictor of mortality in chronic HD patients secondary only to the presence of diabetes. We believe that it is essential to measure the hydration status objectively and quantitatively in order to obtain a more clearly defined

  10. Structural pluralism and all-cause mortality.

    PubMed Central

    Young, F W; Lyson, T A

    2001-01-01

    OBJECTIVES: This study tested the hypothesis that "structural pluralism" reduces age-standardized mortality rates. Structural pluralism is defined as the potential for political competition in communities. METHODS: US counties were the units of analysis. Multiple regression techniques were used to test the hypothesis. RESULTS: Structural pluralism is a stronger determinant of lower mortality than any of the other variables examined--specifically, income, education, and medical facilities. CONCLUSIONS: These findings support the case for a new structural variable, pluralism, as a possible cause of lower mortality, and they indirectly support the significance of comparable ecologic dimensions, such as social trust.

    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

    2008-01-01

    Objective In this systematic review we evaluated the evidence on the association between dioxin exposure and cardiovascular disease (CVD) mortality in humans. Data sources and extraction We conducted a PubMed search in December 2007 and considered all English-language epidemiologic studies and their citations regarding dioxin exposure and CVD mortality. To focus on dioxins, we excluded cohorts that were either primarily exposed to polychlorinated biphenyls or from the leather and perfume industries, which include other cardiotoxic coexposures. Data synthesis We included results from 12 cohorts in the review. Ten cohorts were occupationally exposed. We divided analyses according to two well-recognized criteria of epidemiologic study quality: the accuracy of the exposure assessment, and whether the exposed population was compared with an internal or an external (e.g., general population) reference group. Analyses using internal comparisons with accurate exposure assessments are the highest quality because they minimize both exposure misclassification and confounding due to workers being healthier than the general population (“healthy worker effect”). The studies in the highest-quality group found consistent and significant dose-related increases in ischemic heart disease (IHD) mortality and more modest associations with all-CVD mortality. Their primary limitation was a lack of adjustment for potential confounding by the major risk factors for CVD. Conclusions The results of this systematic review suggest that dioxin exposure is associated with mortality from both IHD and all CVD, although more strongly with the former. However, it is not possible to determine the potential bias, if any, from confounding by other risk factors for CVD. PMID:19057694

    The heterogeneous economic development of Peru and its relationship to the developed countries have determined that the advances of medical science and their influence on infant mortality rates have been unevenly distributed in Peru. Around 1986, the average infant mortality rate was 14/1000 live births in Europe, 118/1000 in Africa, 86/1000 in Asia, 10/1000 in North America, and 62/1000 in Latin America. The unequal development achieved in different countries is the main reason for the different infant mortality rates. The infant mortality rate for each of Peru's provinces around 1981 was estimated using a program for personal computers from the Latin American Demographic Center, which applied the Coale and Trussell variant of the Brass method to information from Peru's 1981 census. The national average infant mortality rate in 1981 was 101.0/1000 live births. 84 provinces, 55%, had high or very high infant mortality rates ranging from 101.0 to 184.0/1000. All were located in the highlands or jungle where the level of poverty is significantly greater than the national average. 28 provinces (18%) had infant mortality rates of 48-80/1000, considered low in Peru. They were almost all in the more developed coastal region. The remaining 41 provinces (27%) with medium infant mortality levels of 81-100/1000 live births were mostly the sites of provincial capitals of departments or other centers with some significant economic activity that attracted health, educational, and other investments.

    Examines impact of war on young children's mortality in 137 countries. Finds that years recently at war (1990-5) interact with years previously at war (1946-89) to elevate mortality rates. Religious composition interacts with years recently at war to reduce effect. Controlling for women's literacy and access to safe water eliminates effect for…

    The objectives of waterfowl management in North America involve population size and harvest. Any management action intended to influence population size must do so through one of four demographic variables: reproduction, mortality, immigration, and emigration. Mortality is especially important because hunting can be strongly influenced by management.

    A global heart failure (HF) registry suggested that the inverse association between body mass index (BMI) and all-cause mortality differed by race, particularly stronger in Japanese patients at 1-year follow-up. Whether this finding was consistent across all East Asian populations was unknown. In a multicenter prospective study in Taiwan, we enrolled 1,301 patients hospitalized for systolic HF from 2013 to 2014 and followed up the mortality after their discharge for a median of 1-year period. Cox proportional hazard regression analyses were used to assess the association of BMI with all-cause mortality. The results showed that BMI was inversely associated with all-cause mortality (hazard ratio and 95% CI per 5-kg/m(2) increase: 0.75 [0.62 to 0.91]) after adjusting for demographics, traditional risk factors, HF severity, and medications at discharge. Subsequently, we sought previous studies regarding the BMI association with mortality for East Asian patients with HF from Medline, and a random-effect meta-analysis was performed by the inverse variance method. The meta-analysis including 7 previous eligible studies (3 for the Chinese and 4 for the Japanese cohorts) and the present one showed similar results that BMI was inversely associated with all-cause mortality (hazard ratio 0.65 [0.58 to 0.73], I(2) = 37%). In conclusion, our study in Taiwan and a collaborative meta-analysis confirmed a strong inverse BMI-mortality association consistently among East Asian patients with HF.

    2016-01-01

    Background More focus on patient-centeredness in care for patients with type 2 diabetes requests increasing attention to diabetes quality management processes on patient-centeredness by managers in primary care groups and outpatient clinics. Although patient-centered care is ultimately determined by the quality of interactions between patients and clinicians at the practice level, it should be facilitated at organizational level too. This nationwide study aimed to assess the state of diabetes quality management on patient-centeredness at organizational level and its possibilities to improve after a tailored intervention. Methods This before–after study compares the quality management on patient-centeredness within Dutch diabetes care groups and outpatient clinics before and after a 1-year stepwise intervention. At baseline, managers of 51 diabetes primary care groups and 28 outpatient diabetes clinics completed a questionnaire about the organization’s quality management program. Patient-centeredness (0%–100%) was operationalized in six subdomains: facilitating self-management support, individualized care plan support, patients’ access to medical files, patient education policy, safeguarding patients’ interests, and formal patient involvement. The intervention consisted of feedback and benchmark and if requested a telephone call and/or a consultancy visit. After 1 year, the managers completed the questionnaire again. The 1-year changes were examined by dependent (non) parametric tests. Results Care groups improved significantly on patient-centeredness (from 47.1% to 53.3%; P=0.002), and on its subdomains “access to medical files” (from 42.0% to 49.4%), and “safeguarding patients’ interests” (from 58.1% to 66.2%). Outpatient clinics, which scored higher at baseline (66.7%) than care groups, did not improve on patient-centeredness (65.6%: P=0.54) or its subdomains. “Formal patient involvement” remained low in both care groups (23.2%) and

  13. Exercise training prevents regain of visceral fat for 1 year following weight loss.

    The purpose of this study was to determine what effect aerobic and resistance exercise training has on gain of visceral fat during the year following weight loss. After being randomly assigned to aerobic training, resistance training, or no exercise training, 45 European-American (EA) and 52 African-American (AA) women lost 12.3 +/- 2.5 kg on a 800 kcal/day diet. Computed tomography was used to measure abdominal subcutaneous and visceral adipose tissue, whereas total fat and regional fat (leg, arm, and trunk) were measured by dual energy X-ray absorptiometry after weight loss and 1 year following the weight loss. Because not all the subjects adhered to the 2 time/week 40 min/day exercise training during the 1-year follow-up, subjects were divided into five groups for analysis: aerobic adherers, aerobic nonadherers, resistance adherers, resistance nonadherers, and no exercise. No significant differences were observed between the aerobic training and resistance training adherers for any variable. However, the aerobic (3.1 kg) and resistance (3.9 kg) exercise adherers gained less weight than any of the other three groups (all >6.2 kg). In addition, the two exercise adherence groups did not significantly increase visceral fat (<0.8%) as compared with the 38% increase for the two nonadhering exercise groups and the 25% for the nonexercise group. In conclusion, as little as 80 min/week aerobic or resistance training had modest positive effects on preventing weight regain following a diet-induced weight loss. More importantly, both aerobic and resistance training prevented regain of potentially harmful visceral fat.

  14. Infant Aphakia Treatment Study: Effects of persistent fetal vasculature on outcome at 1 year of age

    2011-01-01

    Background The Infant Aphakia Treatment Study (IATS) is a randomized trial comparing the treatment of unilateral congenital cataract with primary intraocular lens (IOL) implantation versus aphakic contact lens (CL). The purpose of this study was to compare the outcomes for infants with lens opacity associated with persistent fetal vasculature (PFV) to those without. Methods Retrospective subgroup analysis of grating visual acuity at 1 year of age and adverse events up to 1 year after surgery in eyes identified intraoperatively as having evidence of mild PFV from the IATS. Results Of 83 infants, 18 (22%: 11 CL, 7 IOL) had PFV. Median logMAR visual acuity was 0.88 for patients with PFV and 0.80 for patients without PFV (P = 0.46). One or more adverse events up to one year after surgery occurred in 12 infants (67%) with PFV and 30 infants (46%) without PFV (P = 0.18). The incidence of adverse events was significantly higher in patients with PFV compared to patients without PFV in the CL group (55% vs 20%, P = 0.049) but not in the IOL group (86% vs 71%, P = 0.65), possibly because all children receiving IOLs had higher rates of adverse events when compared to aphakic children (73% vs 29%, P < 0.001). Conclusions Aphakic infants with mild PFV treated with CL had a higher incidence of adverse events following lensectomy compared to children with other forms of unilateral congenital cataract; nevertheless, similar visual outcomes at one year after surgery were obtained.

    OBJECTIVE To characterize the relationships among long-term improvements in peripheral insulin sensitivity (glucose disposal rate [GDR]), fasting glucose, and free fatty acids (FFAs) and concomitant changes in weight and adipose tissue mass and distribution induced by lifestyle intervention in obese individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS We measured GDR, fasting glucose, and FFAs during a euglycemic clamp and adipose tissue mass and distribution, organ fat, and adipocyte size by dual-energy X-ray absorptiometry, CT scan, and adipose tissue biopsy in 26 men and 32 women in the Look-AHEAD trial before and after 1 year of diet and exercise aimed at weight loss. RESULTS Weight and fasting glucose decreased significantly (P < 0.0001) and significantly more in men than in women (−12 vs. −8% and −16 vs. −7%, respectively; P < 0.05), while FFAs during hyperinsulinemia decreased and GDR increased significantly (P < 0.00001) and similarly in both sexes (−53 vs. −41% and 63 vs. 43%; P = NS). Men achieved a more favorable fat distribution by losing more from upper compared with lower and from deeper compared with superficial adipose tissue depots (P < 0.01). Decreases in weight and adipose tissue mass predicted improvements in GDR but not in fasting glucose or fasting FFAs; however, decreases in FFAs during hyperinsulinemia significantly determined GDR improvements. Hepatic fat was the only regional fat measure whose change contributed independently to changes in metabolic variables. CONCLUSIONS Patients with type 2 diabetes undergoing a 1-year lifestyle intervention had significant improvements in GDR, fasting glucose, FFAs and adipose tissue distribution. However, changes in overall weight (adipose tissue mass) and hepatic fat were the most important determinants of metabolic improvements. PMID:20028945

    We assessed 1-year outcomes in patients with atrial fibrillation enrolled in the EurObservational Research Programme AF General Pilot Registry (EORP-AF), in relation to kidney function, as assessed by glomerular filtration rate (eGFR). In a cohort of 2398 patients (median age 69 years; 61% male), eGFR (ml/min/1.73 m2) calculated using the CKD-EPI formula was ≥80 in 35.1%, 50–79 in 47.2%, 30–49 in 13.9% and <30 in 3.7% of patients. In a logistic regression analysis, eGFR category was an independent predictor of stroke/TIA or death, with elevated odds ratios associated with severe to mild renal impairment, ie. eGFR < 30 ml/min/1.73 m2 [OR 3.641, 95% CI 1.572–8.433, p < 0.0001], 30–49 ml/min/1.73 m2 [OR 3.303, 95% CI 1.740–6.270, p = 0.0026] or 50–79 ml/min/1.73 m2 [OR 2.094, 95% CI 1.194–3.672, p = 0.0003]. The discriminant capability for the risk of death was tested among various eGFR calculation algorithms: the best was the Cockcroft-Gault equation adjusted for BSA, followed by Cockcroft-Gault equation, and CKD-EPI equation, while the worst was the MDRD equation. In conclusion in this prospective observational registry, renal function was a major determinant of adverse outcomes at 1 year, and even mild or moderate renal impairments were associated with an increased risk of stroke/TIA/death.

    Objective This randomized double-blind clinical trial compared the performance of posterior composite restorations with or without bevel, after 1-year follow-up. Material and Methods Thirteen volunteers requiring at least two posterior composite restorations were selected. Twenty-nine cavities were performed, comprising 14 without bevel (butt joint) and 15 with bevel preparation of the enamel cavosurface angle. All cavities were restored with simplified adhesive system (Adper Single Bond) and composite resin (Filtek P60). A halogen light curing unit was used through the study. Restorations were polished immediately. Analysis was carried out at baseline, after 6 months and after 1 year by a calibrated evaluator (Kappa), according to the FDI criteria. Data were statistically analyzed by Mann-Whitney test (p<0.05). Results Beveled and non-beveled cavities performed similarly after 1 year follow-up, regarding to fractures and retention, marginal adaptation, postoperative hypersensitivity, recurrence of caries, surface luster and anatomic form. However, for surface and marginal staining, beveled cavities showed significantly better performance (p<0.05) than butt joint restorations. Conclusions It was concluded that the restorations were acceptable after 1 year, but restorations placed in cavities with marginal beveling showed less marginal staining than those placed in non-beveled cavities.

    Background/Aims Spontaneous bacterial peritonitis (SBP) contributes to poorer short-term mortality in cirrhotic patients with ascites. However, it is unknown how long the effect of the first SBP event persists in these patients. Methods The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify and enroll 7,892 cirrhotic patients with ascites who were hospitalized between January 1 and December 31, 2007. All patients were free from episodes of SBP from 1996 to 2006. Results The study included 1,176 patients with SBP. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in this group were 21.8%, 38.9%, 57.5%, and 73.4%, respectively. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in the non-SBP group were 15.7%, 32.5%, 53.3%, and 72.5%, respectively. After adjusting for gender, age, and other medical comorbidities, the adjusted hazard ratios of SBP for 30-day, 30- to 90-day, 90-day to 1-year, and 1- to 3-year mortality were 1.49 (95% confidence interval [CI], 1.30 to 1.71), 1.19 (95% CI, 1.02 to 1.38), 1.04 (95% CI, 0.90 to 1.20), and 0.90 (95% CI, 0.77 to 1.05), respectively, compared with the non-SBP group. Conclusions The effect of SBP on the mortality of cirrhotic patients with ascites disappeared in those surviving more than 90 days after the first SBP event. PMID:27563023

  19. [Maternal mortality in Argentina].

    PubMed

    1994-01-01

    In Argentina, as in most countries, complications of pregnancy and delivery are important causes of mortality of fertile-age women. At the 1994 International Conference on Population and Development in Cairo, governments agreed on the objective of promoting maternity without risk in order to reduce maternal mortality. Maternal mortality rates in many developing countries are much higher than the 10/100,000 live births in the most developed countries. Deficiencies in reporting due either to failure to report deaths or errors in the cause of death are a major impediment to study of maternal mortality. Two studies were conducted recently to provide more accurate data on maternal mortality in Argentina. A study carried out during 1987-89 was designed to measure underregistration of maternal mortality in the federal capital in 1985. Data from death registers were paired with the corresponding clinical histories. The true maternal mortality rate was found to be 91/100,000 rather than the official 50. 38% of maternal deaths rather than the previously estimated 57% were found to be due to complications of illegal abortion. The degree of underreporting in the federal capital, which has the highest proportion of hospital deliveries and most developed infrastructure, suggests that the maternal mortality rate is also much higher than official estimates in other parts of Argentina. Official estimates for 1993 showed a maternal mortality rate of 46/100,000, with very significant regional differentials. A study using the indirect sister survival method was conducted in a low income neighborhood of Zarate in 1991. 8041 persons in 1679 households were interviewed. The resulting estimate of 140/100,000 corresponded to the early 1980s.

    Krupski, Vladimir N.

    Symbolic semantics for logics of proofs based on Mkrtychev models covers the the case of multi-conclusion proof logics. We propose symbolic models for single-conclusion proof logics (FLP and its extensions). The corresponding soundness and completeness theorems are proven. The developed symbolic model technique is used to establish the consistency of contexts required for proof internalization. In particular, we construct an extension of FLP that enjoys the strong proof internalization property with empty context.

  1. Mortality in Asia.

    PubMed

    1981-01-01

    Although the general trend in mortality between 1950 and 1975 in South and East Asia has been downward, there is considerable country-to-country variation in the rate of decline. In countries where combined economic, social, and political circumstances resulted in controlling the disease spectrum (e.g., China, Malaysia, Sri Lanka), mortality levels declined to those seen in low-mortality countries. In most of the large countries of the region however, mortality declined at a slower rate, even slowing down considerably in the 1970's while the death rates remained high (e.g., India, Bangladesh, Thailand, Philippines); this slowing down of mortality level is attributed essentially to the poverty-stricken masses of society which were not able to take advantage of social, technological, and health-promoting behavioral changes conducive to mortality decline. Infant mortality levels, although declining since 1950, followed the same dismal pattern of the general mortality level. The rate varies from less than 10/1000 live births (Japan) to more than 140/1000 (Bangladesh, Laos, Nepal). Generally, rural areas exhibited higher infant mortality than urban areas. The level of child mortality declines with increases in the mother's educational level in Bangladesh, India, Indonesia, Sri Lanka, and Thailand. The largest decline in child mortality occurs when at least 1 parent has secondary education. The premature retardation of mortality decline is caused by several factors: economic development, nutrition and food supply, provision and adequacy of health services, and demographic trends. The outlook for the year 2000 for most of Asia's countries will depend heavily on significant population increases. In most countries, particularly in South Asia, population is expected to increase by 75%, much of it in rural areas and among poorer socioeconomic groups. In view of this, Asia's health planners and policymakers will have to develop health policies which will strike a balance

    Objective To examine changes in colorectal cancer mortality in 34 European countries between 1970 and 2011. Design Retrospective trend analysis. Data source World Health Organization mortality database. Population Deaths from colorectal cancer between 1970 and 2011. Profound changes in screening and treatment efficiency took place after 1988; therefore, particular attention was paid to the evolution of colorectal cancer mortality in the subsequent period. Main outcomes measures Time trends in rates of colorectal cancer mortality, using joinpoint regression analysis. Rates were age adjusted using the standard European population. Results From 1989 to 2011, colorectal cancer mortality increased by a median of 6.0% for men and decreased by a median of 14.7% for women in the 34 European countries. Reductions in colorectal cancer mortality of more than 25% in men and 30% in women occurred in Austria, Switzerland, Germany, the United Kingdom, Belgium, the Czech Republic, Luxembourg, and Ireland. By contrast, mortality rates fell by less than 17% in the Netherlands and Sweden for both sexes. Over the same period, smaller or no declines occurred in most central European countries. Substantial mortality increases occurred in Croatia, the former Yugoslav republic of Macedonia, and Romania for both sexes and in most eastern European countries for men. In countries with decreasing mortality, reductions were more important for women of all ages and men younger than 65 years. In the 27 European Union member states, colorectal cancer mortality fell by 13.0% in men and 27.0% in women, compared with corresponding reductions of 39.8% and 38.8% in the United States. Conclusion Over the past 40 years, there has been considerable disparity in the level of colorectal cancer mortality between European countries, as well as between men and women and age categories. Countries with the largest reductions in colorectal cancer mortality are characterised by better accessibility to screening

    Diabetes mellitus is a frequent comorbid conditions among patients with pneumonia living in the community.The aim of our study is to evaluate the impact of hospitalization for pneumonia on early (30 day) and late mortality (1 year) in patients with type 2 diabetes mellitus.Prospective comparative cohort study of 203 patients with type 2 diabetes hospitalized for pneumonia versus 206 patients with diabetes hospitalized for other noninfectious causes from January 2012 to December 2013 at Policlinico Umberto I (Rome). Enrolled patients were followed up to discharge and up to 1 year after initial hospital admission or death.Overall, 203 patients with type 2 diabetes admitted to hospital for pneumonia were compared to 206 patients with type 2 diabetes admitted for other causes (39.3% decompensated diabetes, 21.4% cerebrovascular diseases, 9.2% renal failure, 8.3% acute myocardial infarction, and 21.8% other causes). Compared to control patients, those admitted for pneumonia showed a higher 30-day (10.8% vs 1%, P < 0.001) and 1-year mortality rate (30.3% vs 16.8%, P < 0.001). Compared to survivors, nonsurvivor patients with pneumonia had a higher incidence of moderate to severe chronic kidney disease, hemodialysis, and malnutrition were more likely to present with a mental status deterioration, and had a higher number of cardiovascular events during the follow-up period. Cox regression analysis found age, Charlson comorbidity index, pH < 7.35 at admission, hemodialysis, and hospitalization for pneumonia as variables independently associated with mortality.Hospitalization for pneumonia is associated with decreased 1-year survival in patients with type 2 diabetes, and appears to be a major determinant of long-term outcome in these patients.

    The research aim was 1) to determine the incidence of maternal mortality in a rural health center area in Sirur, Maharashtra state, India; 2) to determine the relative risk; and 3) to make suggestions about reducing maternal mortality. The data on deliveries was obtained between 1981 and 1984. Medical care at the Rural Training Center was supervised by the Department of Preventive and Social Medicine, the B.J. Medical College in Pune. Deliveries numbered 5994 singleton births over the four years; 5919 births were live births. 15 mothers died: 14 after delivery and 1 predelivery. The maternal mortality rate was 2.5/1000 live births. The maternal causes of death included 9 direct obstetric causes, 3 from postpartum hemorrhage of anemic women, and 3 from puerperal sepsis of anemic women with prolonged labor. 2 deaths were due to eclampsia, and 1 death was unexplained. There were 5 (33.3%) maternal deaths due to indirect causes (3 from hepatitis and 2 from thrombosis). One woman died of undetermined causes. Maternal jaundice during pregnancy was associated with the highest relative risk of maternal death: 106.4. Other relative risk factors were edema, anemia, and prolonged labor. Attributable risk was highest for anemia, followed by jaundice, edema, and maternal age of over 30 years. Maternal mortality at 30 years and older was 3.9/1000 live births. Teenage maternal mortality was 3.3/1000. Maternal mortality among women 20-29 years old was lowest at 2.1/1000. Maternal mortality for women with a parity of 5 or higher was 3.6/1000. Prima gravida women had a maternal mortality rate of 2.9/1000. Parities between 1 and 4 had a maternal mortality rate of 2.3/1000. The lowest maternal mortality was at parity of 3. Only 1 woman who died had received more than 3 prenatal visits. 11 out of 13 women medically examined prenatally were identified with the following risk factors: jaundice, edema, anemia, young or old maternal age, parity, or poor obstetric history.

    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 to 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 vs. 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 (OR 0.86, 95% CI 0.76-0.98, p=0.02) and 12% lower odds of failure-to-rescue (OR 0.88, 95% CI 0.77-1.01, p=0.07) while controlling for nursing factors as well as hospital and patient differences. Conclusions Magnet hospitals have lower mortality than is fully accounted for by measured characteristics of nursing. Magnet recognition likely both identifies existing quality and stimulates further positive organizational behavior that improves patient outcomes. PMID:23047129

    This study examines the relationship between air pollution, measured as concentration of suspended particulates in the atmosphere, and infant mortality due to pneumonia in the metropolitan area of Rio de Janeiro. Multiple linear regression (progressive or stepwise method) was used to analyze infant mortality due to pneumonia, diarrhea, and all causes in 1980, by geographic area, income level, and degree of contamination. While the variable proportion of families with income equivalent to more than two minimum wages was included in the regressions corresponding to the three types of infant mortality, the average contamination index had a statistically significant coefficient (b = 0.2208; t = 2.670; P = 0.0137) only in the case of mortality due to pneumonia. This would suggest a biological association, but, as in any ecological study, such conclusions should be viewed with caution. The authors believe that air quality indicators are essential to consider in studies of acute respiratory infections in developing countries.

    1992-01-01

    Data derived from the Encuesta Nacional de Fecundidad y Salud (ENFES) confirm that overall levels of infant mortality in Mexico have been steadily declining. However, a more specific analysis furnishes evidence that this decline has occurred at varying rates within different social groups, reflecting an increase in social inequalities. The analytical strategy used in this article leads to three basic conclusions: (1) the impact of the economic crisis on infant mortality is reflected not in a reversal of the declining trend but an increase in social inequalities; (2) certain variables universally accepted as determinants of infant mortality, such as mother's education, seem nonsignificant for some social sectors; and (3) certain biodemographic characteristics assumed to have a uniform mortality-related behavior vary among sectors, suggesting that even these constants are determined by social factors.

    Multiple studies show that molecular genetic changes and epigenetic modifications affect the risk of cognitive disability or impairment. However, the role of epigenetic variation in cognitive development of neurotypical young children remains largely unknown. Using data from a prospective, community-based study of mother-infant pairs, we investigated the association of DNA methylation patterns in neonatal umbilical cord blood with cognitive and language development at 1 year of age. No CpG loci achieved genome-wide significance, although a small number of weakly suggestive associations with Bayley-III Receptive Communication scales were noted. While umbilical cord blood is a convenient resource for genetic analyses of birth outcomes, our results do not provide conclusive evidence that its use for DNA methylation profiling yields epigenetic markers that are directly related to postnatal neurocognitive outcomes at 1 year of age.

    The conclusiveness is investigated using recognition processes and one-one correspondence between expressions of a natural language and graphs representing events. The graphs, as conceived in psycholinguistics, are obtained as a result of perception processes. It is possible to generate and process the graphs automatically, using computers and then to convert the resulting graphs into expressions of a natural language. Correctness and conclusiveness of the graphs and sentences are investigated using the fundamental condition for events representation processes. Some consequences of the conclusiveness are discussed, e.g. undecidability of arithmetic, human brain assymetry, correctness of statistical calculations and operations research. It is suggested that the group theory should be imposed on mathematical models of any real system. Proof of the fundamental condition is also presented. 14 references.

    Background Elevated symmetric dimethylarginine (SDMA) has been shown to predict cardiovascular events and all cause mortality in diverse populations. The potential role of SDMA as a risk marker in renal transplant recipients (RTR) has not been investigated. Methods We analyzed SDMA in the placebo arm of the Assessment of Lescol in Renal Transplantation study, a randomized controlled trial of fluvastatin in RTR. Mean follow-up was 5.1 years. Patients were grouped into quartiles based on SDMA levels at study inclusion. Relationships between SDMA and traditional risk factors for graft function and all-cause mortality were analyzed in 925 RTR using univariate and multivariate survival analyses. Results In univariate analysis, SDMA was significantly associated with renal graft loss, all-cause death, and major cardiovascular events. After adjustment for established risk factors including estimated glomerular filtration rate, an elevated SDMA-level (4th quartile, >1.38 μmol/L) was associated with renal graft loss; hazard ratio (HR), 5.51; 95% confidence interval (CI), 1.95–15.57; P=0.001, compared to the 1st quartile. Similarly, SDMA in the 4th quartile was independently associated with all-cause mortality (HR, 4.56; 95% CI, 2.15–9.71; P<0.001), and there was a strong borderline significant trend for an association with cardiovascular mortality (HR, 2.86; 95% CI, 0.99–8.21; P=0.051). Conclusion In stable RTR, an elevated SDMA level is independently associated with increased risk of all-cause mortality and renal graft loss. PMID:24999963

    Although mortality from cardiovascular diseases (CVDs) has been declining, it remains the leading cause of death among urban U.S. blacks. McCord and Freeman reported CVD as the major contributor to excess mortality in Central Harlem. However the disease-specific CVD mortality was not assessed. Thus, it was unclear what the distribution of specific CVDs was in Central Harlem and their contribution to excess mortality. We reviewed the vital statistics records of New York City (NYC) Department of Health for 1990 and identified all cases in which the cause of death was coded as cardiovascular (International Classification of Diseases-ICD, 9th Revision, codes 391, 393-398, 401-404, 410, 411, 414-417, 420-438 and 440-444). The total and disease-specific CVD mortality for NYC and Central Harlem were calculated using the appropriate 1990 census data as the denominator. Central Harlem residents aged between 25-64 years were at least twice as likely to die from cardiovascular causes, compared to NYC residents. Hypertension-related deaths, ICD codes 401 (essential hypertension), 402 (hypertensive heart disease), 403 (hypertensive renal disease), and 404 (hypertensive heart and renal disease), were the major cause of excess death for men and women in Central Harlem. These findings show the importance of hypertension as the main determinant of the excess cardiovascular mortality in urban blacks and suggest an increased risk of cardiovascular death in blacks residing in Central Harlem.

    Objectives To assess contemporary data on characteristics, management and 1-year postdischarge outcomes in Iranian patients hospitalised with acute coronary syndrome (ACS). Setting 11 tertiary care hospitals in 5 major cities in the Islamic Republic of Iran. Participants Patients aged ≥20 and ≤80 years discharged alive with confirmed diagnosis of ACS including ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI) and high-risk unstable angina (HR-UA). Primary and secondary outcome measures Patients were followed up regarding the use of medications and the end points of the study at 1 month and 1 year after discharge. The primary end point of the study was 1-year postdischarge major adverse cardiac and cerebrovascular events (MACCEs), defined as mortality (cardiac and non-cardiac), ACS and cerebrovascular attack (stroke and/or transient ischaemic attack). The secondary end points were hospital admission because of congestive heart failure, revascularisation by coronary artery bypass grafting surgery or percutaneous coronary intervention (PCI), and major and minor bleeds. Results A total of 1799 patients (25.7% STEMI and 74.3% HR-UA/NSTEMI) discharged alive with confirmed diagnosis of ACS were included in the final analysis. During hospitalisation, the majority of the patients received aspirin (98.6%), clopidogrel (91.8%), anticoagulants (93.4%), statins (94.3%) and β-blockers (89.3%). Reperfusion therapy was performed in 62.6% of patients with STEMI (46.3% thrombolytic therapy and 17.3% primary PCI). The mean door-to-balloon and door-to-needle times were 82.9 and 45.6 min, respectively. In our study, 64.7% and 79.5% of the patients in HR-UA/NSTEMI and STEMI groups, respectively, underwent coronary angiography. During the 12 months after discharge, MACCEs occurred in 15.0% of all patients. Conclusions Our study showed that the composition of Iranian patients with ACS regarding the type of ACS is similar to that in developed European

    Salvador, Sérgio F.; Henriques, João Carlos; Munguambe, Missael; Vaz, Rui M. C.; Barros, Henrique P.

    2014-01-01

    Background: In developed countries, the incidence of neonatal hydrocephalus ranges from 3 to 5 cases per 1000 live births, but little is known about the frequency of hydrocephalus in Africa. In Mozambique, there is no primary information related to this disorder, but using the above data, the expected incidence of neonatal hydrocephalus would range from 2900 to 4800 cases per year. Methods: This study is based on 122 children younger than 1 year with neonatal hydrocephalus, followed up between January 2010 and December 2012, their origin and treatment, and aims to evaluate difficulties with diagnosis, treatment, and follow-up in northern Mozambique. Results: Identified cases were mainly less than 6 months old (77%), with severe macrocephaly and the classic stigmata of this condition. A high rate of follow-up loss (44.3%) was detected, particularly among children from more distant locations. Our findings contrast with the expected 1000-1700 cases that would occur in the area during the study period, being considerably lower. Conclusions: Hydrocephalus is a serious problem in sub-Saharan Africa, whose effects can be minimized by a better organization of the health system in hydrocephalus prevention, referral, and follow-up. New management alternatives to provide treatment to more children with this disorder and reduction of the follow-up difficulties caused due to geographical reasons for the children undergoing treatment are essential.

    Purpose: To determine whether hippocampal neurons are lost 12 months after middle-aged rats received a fractionated course of whole-brain irradiation (WBI) that is expected to be biologically equivalent to the regimens used clinically in the treatment of brain tumors. Methods and Materials: Twelve-month-old Fischer 344 X Brown Norway male rats were divided into WBI and control (CON) groups (n = 6 per group). Anesthetized WBI rats received 45 Gy of {sup 137}Cs {gamma} rays delivered as 9 5-Gy fractions twice per week for 4.5 weeks. Control rats were anesthetized but not irradiated. Twelve months after WBI completion, all rats were anesthetized and perfused with paraformaldehyde, and hippocampal sections were immunostained with the neuron-specific antibody NeuN. Using unbiased stereology, total neuron number and the volume of the neuronal and neuropil layers were determined in the dentate gyrus, CA3, and CA1 subregions of hippocampus. Results: No differences in tissue integrity or neuron distribution were observed between the WBI and CON groups. Moreover, quantitative analysis demonstrated that neither total neuron number nor the volume of neuronal or neuropil layers differed between the two groups for any subregion. Conclusions: Impairment on a hippocampal-dependent learning and memory test occurs 1 year after fractionated WBI at middle age. The same WBI regimen, however, does not lead to a loss of neurons or a reduction in the volume of hippocampus.

    2013-01-01

    Purpose Prospective longitudinal research is needed to examine associations between bullying behaviors and trajectories of suicidal ideation and behavior and overall functional impairment. The specific aims of the present study are to: (1) characterize differences in baseline functioning between acutely suicidal adolescents who are classified into bullying perpetrator and non-bully groups and (2) examine the 1-year trajectories of these two groups of adolescents. Method Participants were 433 psychiatrically hospitalized suicidal adolescents (72% female), ages 13 to 17 years. Participants reported suicidal ideation, depression, anxiety, substance use, adaptive functioning, and bullying behavior. Six items from the Youth Self-Report were used to classify adolescents into bullying perpetrator (n = 54) and non-bully (n = 379) groups. Follow-up assessments were conducted at 6 weeks, 3 months, 6 months, and 12 months. Results At hospitalization, adolescents in the bully group reported significantly higher levels of suicidal ideation, substance use, and functional impairment. Suicidal ideation differences remitted at six weeks. The elevated functional impairment of the bullying perpetrator group persisted across the 12-month period. Conclusion Adolescents who met bullying perpetrator group criteria were characterized by more severe suicidal ideation and higher levels of proximal risk factors for suicide. Bullying behavior was not stable over time but was associated with elevated suicide risk when present. These findings highlight the importance of specifically assessing for and targeting bullying behavior at multiple time points when treating suicidal adolescents. PMID:23790201

    Objective The purpose of this study is to describe and discuss laboratory tests ordered on elite athletes in an interdisciplinary sports medicine clinic by a doctor of chiropractic over 1 calendar year. Methods A retrospective review of laboratory tests ordered during routine clinical practice as standard screening and diagnostic tests from November 1, 2009, to November 1, 2010 was performed. Data were collected during clinical encounters at one sports medicine clinic and entered into a database for analysis. Descriptive and frequency statistics were used to describe the tests ordered and the frequency of abnormal findings. Results Five hundred and thirty-nine studies were ordered for diagnostic and routine screenings on 137 athlete patients (86 males, 51 females), representing 49 types of tests. Sample sources included blood, urine, skin lesions, and fecal matter. The most commonly ordered tests were complete blood count, comprehensive metabolic panel, serum ferritin, creatine kinase, serum iron and total iron binding capacity, total cortisol, thyroid stimulating hormone, and lipid panels. There were 217 studies (40%) flagged as abnormal by the reporting laboratory. Conclusion This report provides greater insight into the diverse array of laboratory studies ordered over a 1-year period for diagnosis and screening of elite athletes. A high percentage of the results were flagged as abnormal by the laboratory. These findings show that the unique physiology of the elite athlete must be considered when interpreting laboratory findings in this population. PMID:26257590

    SENTIERI Project (Mortality study of residents in Italian polluted sites) studies mortality of residents in 44 sites of national interest for environmental remediation (Italian polluted sites, IPS). The epidemiological evidence of the causal association between causes of death and exposures was a priori classified into one of these three categories: Sufficient (S), Limited (L) and Inadequate (I). In these sites various environmental exposures are present. Asbestos (or asbestiform fibres as in Biancavilla) has been the motivation for defining six sites as IPSs (Balangero, Emarese, Casale Monferrato, Broni, Bari-Fibronit, Biancavilla). In five of these, increases in malignant neoplasm or pleura mortality are detected; in four of them, results are consistent in both genders. In six other sites (Pitelli, Massa Carrara, Aree del Litorale Vesuviano, Tito, "Aree industriali della Val Basento", Priolo), where other sources of environmental pollution in addition to asbestos are reported, mortality from malignant neoplasm of pleura is increased in both genders in Pitelli, Massa Carrara, Priolo, "Litorale vesuviano". In the time span 1995-2002, a total of 416 extra cases of malignant neoplasm of pleura are detected in the twelve asbestos-polluted sites. Asbestos and pleural neoplasm represent an unique case. Unlike mesothelioma, most causes of death analyzed in SENTIERI have multifactorial etiology; furthermore, in most IPSs multiple sources of different pollutants are present, sometimes concurrently with air pollution from urban areas: in these cases, drawing conclusions on the association between environmental exposures and specific health outcomes might be complicated. Notwithstanding these difficulties, in a number of cases an etiological role could be attributed to some environmental exposures. The attribution could be possible on the basis of increases observed in both genders and in different age classes, and the exclusion of a major role of occupational exposures was

  1. Statistical Conclusion Validity: Some Common Threats and Simple Remedies

    PubMed Central

    García-Pérez, Miguel A.

    2012-01-01

    The ultimate goal of research is to produce dependable knowledge or to provide the evidence that may guide practical decisions. Statistical conclusion validity (SCV) holds when the conclusions of a research study are founded on an adequate analysis of the data, generally meaning that adequate statistical methods are used whose small-sample behavior is accurate, besides being logically capable of providing an answer to the research question. Compared to the three other traditional aspects of research validity (external validity, internal validity, and construct validity), interest in SCV has recently grown on evidence that inadequate data analyses are sometimes carried out which yield conclusions that a proper analysis of the data would not have supported. This paper discusses evidence of three common threats to SCV that arise from widespread recommendations or practices in data analysis, namely, the use of repeated testing and optional stopping without control of Type-I error rates, the recommendation to check the assumptions of statistical tests, and the use of regression whenever a bivariate relation or the equivalence between two variables is studied. For each of these threats, examples are presented and alternative practices that safeguard SCV are discussed. Educational and editorial changes that may improve the SCV of published research are also discussed. PMID:22952465

    Atherosclerosis of femoropopliteal arteries is an important cause of morbidity and mortality. Percutaneous transluminal angioplasty (PTA) has only limited success in treating these arteries, mainly because of the high rate of recurrent stenosis. Cryoplasty has been proposed as a technique which might improve treatment outcome. This study reports our single-center experience with cryoplasty. Thirty-two claudicants, 33 arteries, in whom conservative therapy failed, were consecutively included. Duplex ultrasound (US), angiography, and ankle-brachial index (ABI) measurement were performed before the procedure; ABI and duplex US, 2 weeks and 3, 6, and 12 months after the procedure. Patients' symptoms were categorized according to the Rutherford classification. Lesions were classified as TASC A, B, or C according to angiographic appearance. Differences in ABI before and after the procedure were defined as significant at p < 0.05 by paired t-test. Patency was evaluated using duplex US by determining the peak systolic velocity ratio. Sixteen TASC A lesions, 13 TASC B lesions, and 4 TASC C lesions were included. ABI improved significantly for TASC A lesions 2 weeks and 3 months postprocedure. Patency after 2 weeks, 6 months, and 12 months was 93%, 67%, and 64% for TASC A lesions, 83%, 31%, and 31% for TASC B lesions, and 100%, 50%, and 33% for TASC C lesions, respectively. In conclusion, cryoplasty has good immediate success rates and patency rates similar to the results of conventional PTA in the literature.

  3. Allometry of Herring mortality

    1993-11-01

    The author calculated the relationship between instantaneous natural mortality, M (d[sup [minus]1]), and dry body weight, W ([mu]g), for herring larvae and adults using data from the scientific literature. Geometric mean mortality of adult Pacific herring Clupea pallasi (0.52[center dot]year[sup [minus]1]), was about three times greater than that of adult Atlantic herring Clupea harengus (0.18 year[sup [minus]1]), which may reflect greater reproductive effort per unit size by Pacific herring than by Atlantic herring. Geometric mean mortality of Pacific herring larvae (0.083[center dot]d[sup [minus]1]) was 30% greater than that of Atlantic herring larvae (0.064[center dot]d[sup [minus]1]), but the difference was not significant. The functional regression for Atlantic herring was log[sub e](M) = -0.4924 - 0.4064[center dot]log[sub e](W), and the regression for Pacific herring was log[sub e](M) = 0.1553 0.3935[center dot]log[sub e](W). The regressions provide preliminary estimates of average M of herring eggs and juveniles, life history stages for which there are few direct estimates of mortality. They also indicate that the weight exponent of instantaneous growth of herring should be greater than -0.4. Allometry of herring mortality implies that year-class strength of herring should be positively correlated with size at recruitment. 78 refs., 1 fig., 1 tab.

    In this narrative review, we aim to summarize and discuss the current evidence linking vitamin D and mortality. Low 25-hydroxyvitamin D [25(OH)D] concentrations are associated with an increased risk of mortality. This has been shown in different cohort studies including general populations, as well as various patient cohorts. Some single-study results and meta-analyses indicate that the shape of the relationship between 25(OH)D and mortality follows a U- or a reverse J-shaped curve. Interassay and laboratory differences are, however, a limitation of most previous surveys, and standardization of 25(OH)D measurements is needed for future investigations. Apart from observational data, it has been documented in meta-analyses of randomized controlled trials that vitamin D3 supplementation is associated with a moderate, yet statistically significant, reduction in mortality. This latter finding must be interpreted in light of some limitations such as incomplete follow-up data, but such a reduction of mortality with vitamin D3 supplementation as the finding of meta-analyses of randomized controlled trials strongly argues for the benefits and, importantly, also the safety of vitamin D.

    Objective To determine the mortality rate following total ankle replacement (TAR) and incidence of 90 day pulmonary embolism (PE) along with the associated risk factors. Design Data-linkage study of the UK National Joint Registry (NJR) data and Hospital Episodes Statistics (HES) database. Linkage was performed in a deterministic fashion. HES episodes 90 days after the index procedure were analysed for PE. Mortality data were obtained pertaining to all the index procedures from the NJR for analysis. Participants All primary and revision ankle replacement patients captured on the NJR between February 2008 and February 2013. Results The 90-day mortality following TAR was 0.13% (95% CI 0.03 to 0.52) and 1-year mortality was 0.72% (95% CI 0.40 to 1.30); no deaths were as a result of PE. The incidence of PE within 90 days following primary TAR was 0.51% (95% CI 0.23 to 1.13). There was only one PE following revision surgery. Patients with an Royal College of Surgeons Charlson score greater than zero were at 13 times greater risk of PE (p=0.003). Conclusions There is low incidence of PE following TAR, but multiple comorbidities are a leading risk factor for its occurrence. PMID:27329444

    Background Transcatheter aortic valve implantation has become an option for high-surgical-risk patients with aortic valve disease. Objective To evaluate the in-hospital and one-year follow-up outcomes of transcatheter aortic valve implantation. Methods Prospective cohort study of transcatheter aortic valve implantation cases from July 2009 to February 2015. Analysis of clinical and procedural variables, correlating them with in-hospital and one-year mortality. Results A total of 136 patients with a mean age of 83 years (80-87) underwent heart valve implantation; of these, 49% were women, 131 (96.3%) had aortic stenosis, one (0.7%) had aortic regurgitation and four (2.9%) had prosthetic valve dysfunction. NYHA functional class was III or IV in 129 cases (94.8%). The baseline orifice area was 0.67 ± 0.17 cm2 and the mean left ventricular-aortic pressure gradient was 47.3±18.2 mmHg, with an STS score of 9.3% (4.8%-22.3%). The prostheses implanted were self-expanding in 97% of cases. Perioperative mortality was 1.5%; 30-day mortality, 5.9%; in-hospital mortality, 8.1%; and one-year mortality, 15.5%. Blood transfusion (relative risk of 54; p = 0.0003) and pulmonary arterial hypertension (relative risk of 5.3; p = 0.036) were predictive of in-hospital mortality. Peak C-reactive protein (relative risk of 1.8; p = 0.013) and blood transfusion (relative risk of 8.3; p = 0.0009) were predictive of 1-year mortality. At 30 days, 97% of patients were in NYHA functional class I/II; at one year, this figure reached 96%. Conclusion Transcatheter aortic valve implantation was performed with a high success rate and low mortality. Blood transfusion was associated with higher in-hospital and one-year mortality. Peak C-reactive protein was associated with one-year mortality. PMID:27192383

    Objectives To examine the independent and joint effects of sedentary time and cardiorespiratory fitness (fitness) on all-cause mortality. Design, setting, participants A prospective study of 3141 Cooper Center Longitudinal Study participants. Participants provided information on television (TV) viewing and car time in 1982 and completed a maximal exercise test during a 1-year time frame; they were then followed until mortality or through 2010. TV viewing, car time, total sedentary time and fitness were the primary exposures and all-cause mortality was the outcome. The relationship between the exposures and outcome was examined utilising Cox proportional hazard models. Results A total of 581 deaths occurred over a median follow-up period of 28.7 years (SD=4.4). At baseline, participants’ mean age was 45.0 years (SD=9.6), 86.5% were men and their mean body mass index was 24.6 (SD=3.0). Multivariable analyses revealed a significant linear relationship between increased fitness and lower mortality risk, even while adjusting for total sedentary time and covariates (p=0.02). The effects of total sedentary time on increased mortality risk did not quite reach statistical significance once fitness and covariates were adjusted for (p=0.05). When examining this relationship categorically, in comparison to the reference category (≤10 h/week), being sedentary for ≥23 h weekly increased mortality risk by 29% without controlling for fitness (HR=1.29, 95% CI 1.03 to 1.63); however, once fitness and covariates were taken into account this relationship did not reach statistical significance (HR=1.20, 95% CI 0.95 to 1.51). Moreover, spending >10 h in the car weekly significantly increased mortality risk by 27% in the fully adjusted model. The association between TV viewing and mortality was not significant. Conclusions The relationship between total sedentary time and higher mortality risk is less pronounced when fitness is taken into account. Increased car time, but

    The firm is a fundamental economic unit of contemporary human societies. Studies on the general quantitative and statistical character of firms have produced mixed results regarding their lifespans and mortality. We examine a comprehensive database of more than 25 000 publicly traded North American companies, from 1950 to 2009, to derive the statistics of firm lifespans. Based on detailed survival analysis, we show that the mortality of publicly traded companies manifests an approximately constant hazard rate over long periods of observation. This regularity indicates that mortality rates are independent of a company's age. We show that the typical half-life of a publicly traded company is about a decade, regardless of business sector. Our results shed new light on the dynamics of births and deaths of publicly traded companies and identify some of the necessary ingredients of a general theory of firms. PMID:25833247

    Aim Earlier brain imaging research studies have suggested that brain abnormalities in obsessive-compulsive disorder (OCD) normalize as clinical symptoms improve. However, although many studies have investigated event-related potentials (ERPs) in patients with OCD compared with healthy control subjects, it is currently unknown whether ERP changes reflect pharmacological and psychotherapeutic effects. As such, the current study examined the neurocognitive components of OCD to elucidate the pathophysiological abnormalities involved in the disorder, including the frontal-subcortical circuits. Methods The Yale-Brown Obsessive-Compulsive Scale was used to evaluate 14 adult patients with OCD. The present study also included ten age-, sex-, and IQ-matched controls. The P300 and mismatch negativity (MMN) components during an auditory oddball task at baseline for both groups and after 1 year of treatment for patients with OCD were measured. Results Compared with controls, P300 amplitude was attenuated in the OCD group at Cz and C4 at baseline. Pharmacotherapy and psychotherapy treatment for 1 year reduced OCD symptomology. P300 amplitude after 1 year of treatment was significantly increased, indicating normalization compared with baseline at Fz, Cz, C3, and C4. We found no differences in P300 latency, MMN amplitude, or MMN latency between baseline and after one year of treatment. Conclusion ERPs may be a useful tool for evaluating pharmacological and cognitive behavioral therapy in adult patients with OCD. PMID:27713631

    We investigate the action of global noise and local channels, namely, amplitude-damping, phase-damping, and depolarizing channels, on monogamy of quantum correlations, such as negativity and quantum discord, in three-qubit systems. We discuss the monotonic and non-monotonic variation, and robustness of the monogamy scores. By using monogamy scores, we propose a two-step protocol to conclusively identify the noise applied to the quantum system, by using generalized Greenberger-Horne-Zeilinger and generalized W states as resource states. We discuss a possible generalization of the results to higher number of parties.

    Background India has long been thought to have more snakebites than any other country. However, inadequate hospital-based reporting has resulted in estimates of total annual snakebite mortality ranging widely from about 1,300 to 50,000. We calculated direct estimates of snakebite mortality from a national mortality survey. Methods and Findings We conducted a nationally representative study of 123,000 deaths from 6,671 randomly selected areas in 2001–03. Full-time, non-medical field workers interviewed living respondents about all deaths. The underlying causes were independently coded by two of 130 trained physicians. Discrepancies were resolved by anonymous reconciliation or, failing that, by adjudication. A total of 562 deaths (0.47% of total deaths) were assigned to snakebites. Snakebite deaths occurred mostly in rural areas (97%), were more common in males (59%) than females (41%), and peaked at ages 15–29 years (25%) and during the monsoon months of June to September. This proportion represents about 45,900 annual snakebite deaths nationally (99% CI 40,900 to 50,900) or an annual age-standardised rate of 4.1/100,000 (99% CI 3.6–4.5), with higher rates in rural areas (5.4/100,000; 99% CI 4.8–6.0), and with the highest state rate in Andhra Pradesh (6.2). Annual snakebite deaths were greatest in the states of Uttar Pradesh (8,700), Andhra Pradesh (5,200), and Bihar (4,500). Conclusions Snakebite remains an underestimated cause of accidental death in modern India. Because a large proportion of global totals of snakebites arise from India, global snakebite totals might also be underestimated. Community education, appropriate training of medical staff and better distribution of antivenom, especially to the 13 states with the highest prevalence, could reduce snakebite deaths in India.

    A bedside-available transcatheter aortic valve implantation (TAVI)-dedicated prognostic risk score is an unmet clinical need. We aimed to develop such a risk score predicting 1-year mortality post-TAVI and to compare it with the performance of the logistic EuroSCORE (LES) I and LES-II and the Society of Thoracic Surgeons' (STS) score. Baseline variables of 511 consecutive patients who underwent TAVI that were independently associated with 1-year mortality post-TAVI were included in the "TAVI2-SCORe." Discrimination and calibration abilities of the novel score were assessed and compared with surgical risk scores. One-year mortality was 17.0% (n = 80 of 471). Porcelain thoracic aorta (hazard ratio [HR] 2.56), anemia (HR 2.03), left ventricular dysfunction (HR 1.98), recent myocardial infarction (HR 3.78), male sex (HR 1.81), critical aortic valve stenosis (HR 2.46), old age (HR 1.68), and renal dysfunction (HR 1.76) formed the TAVI2-SCORe (all p <0.05). According to the number of points assigned (1 for each variable and 2 for infarction), patients were stratified into 5 risk categories: 0, 1 (HR 2.6), 2 (HR 3.6), 3 (HR 10.5), and ≥4 (HR 17.6). TAVI2-SCORe showed better discrimination ability (Harrells' C statistic 0.715) compared with LES-I, LES-II, and STS score (0.609, 0.633, and 0.50, respectively). Cumulative 1-year survival rate was 54% versus 88% for patients with TAVI2-SCORE ≥3 versus <3 points, respectively (p <0.001). Contrary to surgical risk scores, there was no significant difference between observed and expected 1-year mortality for all TAVI2-SCORe risk strata (all p >0.05, Hosmer-Lemeshow statistic 0.304), suggesting superior calibration performance. In conclusion, the TAVI2-SCORe is an accurate, simple, and bedside-available score predicting 1-year mortality post-TAVI, outperforming conventional surgical risk scores for this end point.

    Objectives. 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. Methods. 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. Results. 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. Conclusions. 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.

    Introduction On 11 March 2011, a magnitude 9.0 earthquake caused a huge tsunami that struck Northeast Japan, resulting in nearly 20 000 deaths. We investigated mortality patterns by age, sex, and region in the 3 most severely affected prefectures. Methods Using police data on earthquake victims in Iwate, Miyagi, and Fukushima prefectures, mortality rates by sex, age group, and region were calculated, and regional variability in mortality rates across age groups was compared using rate ratios (RRs), with the rates in Iwate as the reference. Results In all regions, age-specific mortality showed a tendency to increase with age; there were no sex differences. Among residents of Iwate, mortality was markedly lower among school-aged children as compared with other age groups. In northern Miyagi and the southern part of the study area, RRs were higher among school-aged children than among other age groups. Conclusions The present study could not address the reasons for the observed mortality patterns and regional differences. To improve preparedness policies, future research should investigate the reasons for regional differences. PMID:23089585

    Background: Socioeconomic status (SES) can greatly affect the clinical outcome of medical problems. We sought to assess the in-hospital mortality of patients with the acute coronary syndrome (ACS) according to their SES. Methods: All patients admitted to Tehran Heart Center due to 1st-time ACS between March 2004 and August 2011 were assessed. The patients who were illiterate/lowly educated (≤5 years attained education) and were unemployed were considered low-SES patients and those who were employed and had high educational levels (>5 years attained education) were regarded as high-SES patients. Demographic, clinical, paraclinical, and in-hospital medical progress data were recorded. Death during the course of hospitalization was considered the end point, and the impact of SES on in-hospital mortality was evaluated. Results: A total of 6246 hospitalized patients (3290 low SES and 2956 high SES) were included (mean age = 60.3 ± 12.1 years, male = 2772 [44.4%]). Among them, 79 (1.26%) patients died. Univariable analysis showed a significantly higher mortality rate in the low-SES group (1.9% vs. 0.6%; P < 0.001). After adjustment for possible cofounders, SES still showed a significant effect on the in-hospital mortality of the ACS patients in that the high-SES patients had a lower in-hospital mortality rate (odds ratio: 0.304, 95% confidence interval: 0.094–0.980; P = 0.046). Conclusions: This study found that patients with low SES were at a higher risk of in-hospital mortality due to the ACS. Furthermore, the results suggest the need for increased availability of jobs as well as improved levels of education as preventive measures to curb the unfolding deaths owing to coronary artery syndrome.

    Objective We investigated the one-year pregnancy rates for emergency contraception (EC) users who selected the copper T380 IUD or oral levonorgestrel (LNG) for EC. Study Design This prospective study followed women for 1 year after choosing either the copper T380 IUD or oral LNG for EC. The study was powered to detect a 6% difference in pregnancy rates within the year after presenting for EC. Results Of the 542 women who presented for EC, agreed to participate in the trial, and meet inclusion criteria, 215 (40%) chose the copper IUD and 327 (60%) chose oral LNG. In the IUD group, 127 (59%) were nulligravid. IUD insertion failed in 42 women (19%). The 1-year follow-up rate was 443/542 (82%); 64% of IUD users contacted at 1 year still had their IUDs in place. The 1-year cumulative pregnancy rate in women choosing the IUD was 6.5% vs. 12.2% in those choosing oral LNG (HR= 0.53, 95% CI: 0.29–0.97, p=0.041). By type of EC method actually received, corresponding values were 5.2% for copper IUD users vs. 12.3% for oral LNG users, HR 0.42 (95% CI: 0.20–0.85, p= 0.017). A multivariable logistic regression model controlling for demographic variables demonstrates that women who chose the IUD for EC had fewer pregnancies in the following year than those who chose oral LNG (HR 0.50, 95% CI: 0.26–0.96, p=0.037). Conclusion One year after presenting for EC women choosing the copper IUD for EC were half as likely to have a pregnancy compared to those choosing oral LNG. PMID:24332433

    Objective To investigate the mortality associated with cardiovascular diseases and the effect of estrogen treatment in women who underwent unilateral or bilateral oophorectomy before menopause. Design We conducted a cohort study with long-term follow-up of women in Olmsted County, MN, who underwent either unilateral or bilateral oophorectomy before the onset of menopause from 1950 through 1987. Each member of the oophorectomy cohort was matched by age to a referent woman from the same population who had not undergone any oophorectomy. We studied the mortality associated with cardiovascular disease in a total of 1,274 women with unilateral oophorectomy, 1,091 women with bilateral oophorectomy, and 2,383 referent women. Results Women who underwent unilateral oophorectomy experienced a reduced mortality associated with cardiovascular disease compared with referent women (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67–0.99; P = 0.04). By contrast, women who underwent bilateral oophorectomy before age 45 years experienced an increased mortality associated with cardiovascular disease compared with referent women (HR, 1.44; 95% CI, 1.01–2.05; P = 0.04). Within this age stratum, the HR for mortality was significantly elevated in women who were not treated with estrogen through age 45 years or longer (HR, 1.84; 95% CI, 1.27–2.68; P = 0.001) but not in women treated (HR, 0.65; 95% CI, 0.30–1.41; P = 0.28; test of interaction, P = 0.01). Mortality was further increased after excluding deaths associated with cerebrovascular causes. Conclusions Bilateral oophorectomy performed before age 45 years is associated with increased cardiovascular mortality, especially with cardiac mortality. However, estrogen treatment may reduce this risk. PMID:19034050

    In this article the author criticizes the methodology and the findings of an article by Mauldin and Berelson which appeared in 1978 in Studies in Family Planning about population decrease in developing countries and about its implications on population policies. According to the author that article did not take into consideration: 1) the fact that socioeconomic conditions in a given country are more important than family planning programs for a decrease in fertility rate; 2) the fact that it is not known which kinds of family planning programs are more effective, and which kind of social level is more conducive to fertility decrease; and, 3) the status and educational level of women in the countries studied. In conclusion, the author states that the findings of Mauldin and Berelson, although interesting, imply arbitrary procedures and statistics, and cannot be used for the purpose of population policy.

    Probabilistic risk assessment (PRA) techniques and insights have been employed during an investigation entitled the Equipment Qualification (EQ)-Risk Scoping Study to assess the risk significance of equipment qualification issues. This approach for evaluating EQ issues suggests that some issues are not risk significant while some have a significant potential to increase risk. For example, EQ issues associated with long term accident equipment operability are not risk significant. Alternatively, there are selected system operations that require equipment not qualified for important accident environments. Though the study demonstrated that PRA does provide insights that modify perceptions regarding the importance of various EQ issues, it should be noted that PRA methods currently cannot define the risk significance for some EQ issues. Additional discussion regarding the study's results and conclusions is provided. 6 refs.

    Quantum steering allows two parties to verify shared entanglement even if one measurement device is untrusted. A conclusive demonstration of steering through the violation of a steering inequality is of considerable fundamental interest and opens up applications in quantum communication. To date all experimental tests with single photon states have relied on post-selection, allowing untrusted devices to cheat by hiding unfavorable events in losses. Here we close this ``detection loophole'' by combining a highly efficient source of entangled photon pairs with superconducting transition edge sensors. We achieve an unprecedented ˜62% conditional detection efficiency of entangled photons and violate a steering inequality with the minimal number of measurement settings by 48 standard deviations. Our results provide a clear path to practical applications of steering and to a photonic loophole-free Bell test.

    The aim of this systematic review (PubMed, www.ncbi.nlm.nih.gov/pubmed and Cochrane, www.cochrane.org; last entry 31 December 2014) was to present data from recent clinical studies investigating parenteral trace element provision in adult patients and to draw conclusions for clinical practice. Important physiological functions in human metabolism are known for nine trace elements: selenium, zinc, copper, manganese, chromium, iron, molybdenum, iodine and fluoride. Lack of, or an insufficient supply of, these trace elements in nutrition therapy over a prolonged period is associated with trace element deprivation, which may lead to a deterioration of existing clinical symptoms and/or the development of characteristic malnutrition syndromes. Therefore, all parenteral nutrition prescriptions should include a daily dose of trace elements. To avoid trace element deprivation or imbalances, physiological doses are recommended. PMID:27049031

    Background. Cryptococcal meningitis (CM) is a leading cause of death in individuals infected with human immunodeficiency virus (HIV). Identifying factors associated with mortality informs strategies to improve outcomes. Methods. Five hundred one patients with HIV-associated CM were followed prospectively for 10 weeks during trials in Thailand, Uganda, Malawi, and South Africa. South African patients (n = 266) were followed for 1 year. Similar inclusion/exclusion criteria were applied at all sites. Logistic regression identified baseline variables independently associated with mortality. Results. Mortality was 17% at 2 weeks and 34% at 10 weeks. Altered mental status (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.7–5.9), high cerebrospinal fluid (CSF) fungal burden (OR, 1.4 per log10 colony-forming units/mL increase; 95% CI, 1.0–1.8), older age (>50 years; OR, 3.9; 95% CI, 1.4–11.1), high peripheral white blood cell count (>10 × 109 cells/L; OR, 8.7; 95% CI, 2.5–30.2), fluconazole-based induction treatment, and slow clearance of CSF infection were independently associated with 2-week mortality. Low body weight, anemia (hemoglobin <7.5 g/dL), and low CSF opening pressure were independently associated with mortality at 10 weeks in addition to altered mental status, high fungal burden, high peripheral white cell count, and older age. In those followed for 1 year, overall mortality was 41%. Immune reconstitution inflammatory syndrome occurred in 13% of patients and was associated with 2-week CSF fungal burden (P = .007), but not with time to initiation of antiretroviral therapy (ART). Conclusions. CSF fungal burden, altered mental status, and rate of clearance of infection predict acute mortality in HIV-associated CM. The results suggest that earlier diagnosis, more rapidly fungicidal amphotericin-based regimens, and prompt immune reconstitution with ART are priorities for improving outcomes. PMID:24319084

  6. Making sense of mortality.

    PubMed

    Prior, L

    1985-07-01

    This paper focuses upon the collection and processing of government mortality statistics, and especially upon the organisational and theoretical contexts within which such statistics are assembled. Two items of mortality data in particular are examined with a view to illustrating the broader issues: medical cause of death, and social class of deceased. Using a 10 per cent sample of 1981 Belfast death certificates as a base, the paper attempts to trace the specific stages through which the cause of death and social class data have to pass prior to their incorporation into mortality reports. The paper indicates that there are numerous grounds for believing that both kinds of data are flawed at their points of origin, and that the transformations which the data undergo during coding procedures leads to further distortions of our image of mortality and its social base. It is argued that these flaws and distortions are only partly due to technical and organisational shortcomings, and more likely due to weaknesses in the theoretical frameworks through which the data are sifted. The paper concludes by suggesting that the existing arrangements for registering deaths, dominated as they are by the principles of forensic medicine, are more properly viewed as a system for policing the dead, than as a mechanism for generating worthwhile data about diseases and their social distribution.

    Objective To assess the extent to which observed associations between income inequality and mortality at population level are statistical artifacts. Design Indirect "what if" simulation using observed risks of mortality at individual level as a function of income to construct hypothetical state-level mortality specific for age and sex as if the statistical artifact argument were 100% correct. Method Data from the 1990 census for the 50 US states plus Washington, DC, were used for population distributions by age, sex, state, and income range; data disaggregated by age, sex, and state from the Centers for Disease Control and Prevention were used for mortality; and regressions from the national longitudinal mortality study were used for the individual-level relation between income and risk of mortality. Results Hypothetical mortality, although correlated with inequality (as implied by the logic of the statistical artifact argument), showed a weaker association with the level of income inequality in each state than the observed mortality. Conclusions The observed associations in the United States at the state level between income inequality and mortality cannot be entirely or substantially explained as statistical artifacts of an underlying individual-level relation between income and mortality. There remains an important association between income inequality and mortality at state level above anything that could be accounted for by any statistical artifact. This result reinforces the need to consider a broad range of factors, including the social milieu, as fundamental determinants of health.

    Background: Prostate cancer mortality has been decreasing in several high income countries and previous studies analysed the trends mostly according to geographical criteria. We aimed to identify patterns in the time trends of prostate cancer mortality across countries using a model-based approach. Methods: Model-based clustering was used to identify patterns of variation in prostate cancer mortality (1980–2010) across 37 European, five non-European high-income countries and four leading emerging economies. We characterised the patterns observed regarding the geographical distribution and gross national income of the countries, as well as the trends observed in mortality/incidence ratios. Results: We identified three clusters of countries with similar variation in prostate cancer mortality: pattern 1 (‘no mortality decline'), characterised by a continued increase throughout the whole period; patterns 2 (‘later mortality decline') and 3 (‘earlier mortality decline') depict mortality declines, starting in the late and early 1990s, respectively. These clusters are also homogeneous regarding the variation in the prostate cancer mortality/incidence ratios, while are heterogeneous with reference to the geographical region of the countries and distribution of the gross national income. Conclusion: We provide a general model for the description and interpretation of the trends in prostate cancer mortality worldwide, based on three main patterns. PMID:23660943

    A brief analysis of data from the records of the Government Hospital for Women and Children in Madras for a 36-year period (1929-1964) is presented. India with a population of over 550 million has only 1 doctor for each 6000 population. For the 80% of the population which is rural, the doctor ratio is only 88/1 million. There is also a shortage of paramedical personnel. During the earlier years of this study period, abortions, puerperal infections; hemorrhage, and toxemia accounted for nearly 75% of all meternal deaths, while in later years deaths from these causes were 40%. Among associated factors in maternal mortality, anemia was the most frequent, it still accounts for 20% and is a contributory factor in another 20%. The mortality from postpartum hemorrhage was 9.3% but has now decreased to 2.8%. Eclampsia is a preventable disease and a marked reduction in maternal and perinatal mortality from this cause has been achieved. Maternal deaths from puerperal infections have dropped from 25% of all maternal deaths to 7%. Uterine rupture has been reduced from 75% to 9.3% due to modern facilities. Operative deliveries still have an incidence of 2.1% and a mortality rate of 1.4% of all deliveries. These rates would be further reduced by more efficient antenatal and intranatal care. Reported perinatal mortality of infants has been reduced from 182/1000 births to an average of 78/1000 in all areas, but is 60.6/1000 in the city of Madras. Socioeconomic standards play an important role in perinatal mortality, 70% of such deaths occurring in the lowest economic groups. Improvement has been noted in the past 25 years but in rural areas little progress has been made. Prematurity and low birth weights are still larger factors in India than in other countries, with acute infectious diseases, anemia, and general malnutrition among mothers the frequent causes. Problems requiring further efforts to reduce maternal and infant mortality are correct vital statistics, improved

    AIM: To investigate whether or not bariatric surgery weight outcomes vary by ethnicity in a large, nationally representative sample of adolescents. METHODS: The Bariatric Outcomes Longitudinal Database was used for analysis and contains data on surgeries performed on adolescents from 2004 to 2010 from 423 surgeons at 360 facilities across the United States Adolescents (n = 827) between 11 and 19 years old who underwent either gastric bypass or adjustable gastric banding surgery were included in the analysis. Outcome measures included changes in anthropometric measurements [weight (kg) and body mass index] from baseline to 3 (n = 739), 6 (n = 512), and 12 (n = 247) mo after surgery. RESULTS: A year after patients underwent either gastric bypass (51%) or adjustable gastric banding (49%) surgery, mean estimated weight loss for all ethnic groups differed by a maximum of only 1.5 kg, being 34.3 kg (95%CI: 30.0-38.5 kg) for Hispanics, 33.8 kg (95%CI: 27.3-40.3 kg) for non-Hispanic blacks, and 32.8 kg (95%CI: 30.9-34.7 kg) for non-Hispanic whites. No overall pairwise group comparisons were significant, indicating that no ethnic group had better weight loss outcomes than did another. CONCLUSION: Bariatric surgery substantially reduces the weight of severely obese adolescents at 1 year post-procedure with little variation by ethnicity and/or gender. These results suggest that bariatric surgery is a safe and reasonable treatment for all severely obese adolescents with the appropriate indications. PMID:24147204

    Objectives: To evaluate the feasibility and efficacy of robotic-assisted laparoscopic pyeloplasty. Laparoscopic pyeloplasty has been shown to have a success rate comparable to that of the open surgical approach. However, the steep learning curve has hindered its acceptance into mainstream urologic practice. The introduction of robotic assistance provides advantages that have the potential to facilitate precise dissection and intracorporeal suturing. Methods: A total of 50 patients underwent robotic-assisted laparoscopic dismembered pyeloplasty. A four-trocar technique was used. Most patients were discharged home on day 1, with stent removal at 3 weeks. Patency of the ureteropelvic junction was assessed in all patients with mercaptotriglycylglycine Lasix renograms at 1, 3, 6, 9, and 12 months, then every 6 months for 1 year, and then yearly. Results: Each patient underwent a successful procedure without open conversion or transfusion. The average estimated blood loss was 40 ml. The operative time averaged 122 minutes (range 60 to 330) overall. Crossing vessels were present in 30% of the patients and were preserved in all cases. The time for the anastomosis averaged 20 minutes (range 10 to 100). Intraoperatively, no complications occurred. Postoperatively, the average hospital stay was 1.1 days. The stents were removed at an average of 20 days (range 14 to 28) postoperatively. The average follow-up was 11.7 months; at the last follow-up visit, each patient was doing well. Of the 50 patients, 48 underwent one or more renograms, demonstrating stable renal function, improved drainage, and no evidence of recurrent obstruction. Conclusions: Robotic-assisted laparoscopic pyeloplasty is a feasible technique for ureteropelvic junction reconstruction. The procedure provides a minimally invasive alternative with good short-term results.

    Background Lifelong exercise training maintains a youthful compliance of the left ventricle (LV), whereas a year of exercise training started later in life fails to reverse LV stiffening, possibly because of accumulation of irreversible advanced glycation end products. Alagebrium breaks advanced glycation end product crosslinks and improves LV stiffness in aged animals. However, it is unclear whether a strategy of exercise combined with alagebrium would improve LV stiffness in sedentary older humans. Methods and Results Sixty-two healthy subjects were randomized into 4 groups: sedentary+placebo; sedentary+alagebrium (200 mg/d); exercise+placebo; and exercise+alagebrium. Subjects underwent right heart catheterization to define LV pressure–volume curves; secondary functional outcomes included cardiopulmonary exercise testing and arterial compliance. A total of 57 of 62 subjects (67±6 years; 37 f/20 m) completed 1 year of intervention followed by repeat measurements. Pulmonary capillary wedge pressure and LV end-diastolic volume were measured at baseline, during decreased and increased cardiac filling. LV stiffness was assessed by the slope of LV pressure–volume curve. After intervention, LV mass and end-diastolic volume increased and exercise capacity improved (by ≈8%) only in the exercise groups. Neither LV mass nor exercise capacity was affected by alagebrium. Exercise training had little impact on LV stiffness (training×time effect, P=0.46), whereas alagebrium showed a modest improvement in LV stiffness compared with placebo (medication×time effect, P=0.04). Conclusions Alagebrium had no effect on hemodynamics, LV geometry, or exercise capacity in healthy, previously sedentary seniors. However, it did show a modestly favorable effect on age-associated LV stiffening. PMID:24130005

    Purpose: To report the safety and the effectiveness of deep sclerectomy (DS) with a new nonabsorbable uveoscleral hema implant (Esnoper-Clip) designed to increase trabecular and uveoscleral outflow and to achieve higher intrascleral blebs. Materials and Methods: Twenty-seven eyes of 27 patients with open-angle glaucoma, who underwent DS with an Esnoper-Clip implant, were included in this study. All patients were followed up after 12 months. Results: A significant decrease in intraocular pressure was observed after surgery, changing from a preoperative mean of 26.6±5.2 mm Hg to a postoperative mean of 15.3±5 mm Hg (P<0.001) at 12 months. There was also a significant reduction in the number of glaucoma drugs needed, varying from 2.5 per patient to 0.3 (P<0.001) 1 year after surgery. The main intrascleral lake height and volume at 12 months was 0.7±0.1 mm and 3.9±1.3 mm3, respectively. No intraoperative complications occurred. The main postoperative complications were a positive Seidel test result at 24 hours in 2 eyes (7.4%), hyphema in 2 eyes (7.4%), and choroidal detachment in 1 eye (3.7%). All these complications resolved successfully. The need for additional mitomycin-C injections was recorded in 4 eyes (14.8%), twice in 2 of them. Twelve eyes (44.4%) underwent postsurgical Nd:YAG laser goniopuncture with a mean time between surgery and this procedure of 4.3 months. Mean intraocular pressure after Nd:YAG laser goniopuncture decreased from 19.2 to 15.5 mm Hg (P<0.001). Conclusion: DS with an uveoscleral hema implant (Esnoper-Clip) is a safe and effective technique for the management of open-angle glaucoma. PMID:25836660

    Background Chagas cardiomyopathy is a chronic sequela of infection by the parasite, Trypanosoma cruzi. Advanced cardiomyopathy is associated with a high mortality rate, and clinical characteristics have been used to predict mortality risk. Though multiple biomarkers have been associated with Chagas cardiomyopathy, it is unknown how these are related to survival. Objectives Our study aimed to identify biomarkers associated with mortality in individuals with severe Chagas cardiomyopathy in an urban Bolivian hospital. Methods The population included individuals with and without T. cruzi infection recruited in an urban hospital in Santa Cruz, Bolivia. Baseline characteristics, ECG findings, medications, and serum cardiac biomarker levels (BNP, NTproBNP, CKMB, troponin I, MMP-2, MMP-9, TIMP-1, TIMP-2, TGFb1, and TGFb2) were ascertained. Echocardiograms were preferentially performed on those with cardiac symptoms or electrocardiogram abnormalities. Participants were contacted by phone approximately 1 year after initial evaluation; deaths were reported by family members. Receiver operating characteristic curves were used to optimize cut-off values for each marker. For markers with area under curve > 0.55, Cox proportional hazards models were performed to determine the hazards ratio (HR) and 95% confidence interval (CI) for the association of each marker with mortality. Results The median follow-up time was 14.1 months (interquartile range 12.5- 16.7 months). Of 254 individuals with complete cardiac data, 220 (87%) had follow-up data. Of 50 patients with severe Chagas cardiomyopathy, 20 (40%) had died. Higher baseline levels of BNP (HR[95% CI]:3.1 [1.2, 8.4]), NTproBNP (4.4[1.8,11.0]), CKMB (3.3[1.3, 8.0]), and MMP-2 (4.2[1.5, 11.8]) were significantly associated with subsequent mortality. Conclusions Severe Chagas cardiomyopathy is associated with high short-term mortality. BNP, NTproBNP, CKMB and MMP2 have added predictive value for mortality, even in the presence of

    Background: Several epidemiological studies have reported that long-term exposure to fine particulate matter (PM2.5) is associated with higher mortality. Evidence regarding contributions of PM2.5 constituents is inconclusive. Objectives: We assembled a data set of 12.5 million Medicare enrollees (≥ 65 years of age) to determine which PM2.5 constituents are a) associated with mortality controlling for previous-year PM2.5 total mass (main effect); and b) elevated in locations exhibiting stronger associations between previous-year PM2.5 and mortality (effect modification). Methods: For 518 PM2.5 monitoring locations (eastern United States, 2000–2006), we calculated monthly mortality rates, monthly long-term (previous 1-year average) PM2.5, and 7-year averages (2000–2006) of major PM2.5 constituents [elemental carbon (EC), organic carbon matter (OCM), sulfate (SO42–), silicon (Si), nitrate (NO3–), and sodium (Na)] and community-level variables. We applied a Bayesian hierarchical model to estimate location-specific mortality rates associated with previous-year PM2.5 (model level 1) and identify constituents that contributed to the spatial variability of mortality, and constituents that modified associations between previous-year PM2.5 and mortality (model level 2), controlling for community-level confounders. Results: One–standard deviation (SD) increases in 7-year average EC, Si, and NO3– concentrations were associated with 1.3% [95% posterior interval (PI): 0.3, 2.2], 1.4% (95% PI: 0.6, 2.4), and 1.2% (95% PI: 0.4, 2.1) increases in monthly mortality, controlling for previous-year PM2.5. Associations between previous-year PM2.5 and mortality were stronger in combination with 1-SD increases in SO42– and Na. Conclusions: Long-term exposures to PM2.5 and several constituents were associated with mortality in the elderly population of the eastern United States. Moreover, some constituents increased the association between long-term exposure to PM2.5 and

    The present study examined the jumping to conclusions reasoning bias across the continuum of delusional ideation by investigating individuals with active delusions, delusion prone individuals, and non-delusion prone individuals. Neutral and highly self-referent probabilistic reasoning tasks were employed. Results indicated that individuals with delusions gathered significantly less information than delusion prone and non-delusion prone participants on both the neutral and self-referent tasks, (p<.001). Individuals with delusions made less accurate decisions than the delusion prone and non-delusion prone participants on both tasks (p<.001), yet were more confident about their decisions than were delusion prone and non-delusion prone participants on the self-referent task (p=.002). Those with delusions and those who were delusion prone reported higher confidence in their performance on the self-referent task than they did the neutral task (p=.02), indicating that high self-reference impacted information processing for individuals in both of these groups. The results are discussed in relation to previous research in the area of probabilistic reasoning and delusions. PMID:17052687

  17. The harms of enhancement and the conclusive reasons view.

    Many critics of bioenhancement go to considerable lengths to establish the existence of reasons against pursuing bioenhancements but do little to establish the absence of reasons in favor. This suggests that they accept what Allen Buchanan has called the conclusive reasons view (CRV). According to this view, our reasons against bioenhancement are obviously decisive, so there is no need to balance them against countervailing reasons. Buchanan criticizes the CRV by showing that the reasons most commonly adduced against bioenhancement are not decisive, or, at least, not obviously so. In this article, I suggest that both Buchanan and the authors to whom he is responding underestimate the strength of the case for the CRV. There are, I argue, harm-based reasons against bioenhancement that provide stronger support to the CRV than the reasons that have most often been adduced by critics of enhancement. However, I then argue that even these harm-based reasons are not obviously decisive. Thus, I ultimately agree with Buchanan about the falsity of the CRV, though I disagree with him about the reasons for its falsity.

    Objective The objective of the CARRECT software is to make cutting edge statistical methods for reducing bias in epidemiological studies easy to use and useful for both novice and expert users. Introduction Analyses produced by epidemiologists and public health practitioners are susceptible to bias from a number of sources including missing data, confounding variables, and statistical model selection. It often requires a great deal of expertise to understand and apply the multitude of tests, corrections, and selection rules, and these tasks can be time-consuming and burdensome. To address this challenge, Aptima began development of CARRECT, the Collaborative Automation Reliably Remediating Erroneous Conclusion Threats system. When complete, CARRECT will provide an expert system that can be embedded in an analyst’s workflow. CARRECT will support statistical bias reduction and improved analyses and decision making by engaging the user in a collaborative process in which the technology is transparent to the analyst. Methods Older approaches to imputing missing data, including mean imputation and single imputation regression methods, have steadily given way to a class of methods known as “multiple imputation” (hereafter “MI”; Rubin 1987). Rather than making the restrictive assumption that the data are missing completely at random (MCAR), MI typically assumes the data are missing at random (MAR). There are two key innovations behind MI. First, the observed values can be useful in predicting the missing cells, and thus specifying a joint distribution of the data is the first step in implementing the models. Second, single imputation methods will likely fail not only because of the inherent uncertainty in the missing values but also because of the estimation uncertainty associated with generating the parameters in the imputation procedure itself. By contrast, drawing the missing values multiple times, thereby generating m complete datasets along with the

    Little is known about the long-term sequelae of community-acquired pneumonia (CAP). Therefore, we describe the long-term morbidity and mortality of patients after pneumonia requiring hospitalization. We specifically hypothesized that the Pneumonia Severity Index (PSI), designed to predict 30-day pneumonia-related mortality, would also be associated with longer-term all-cause mortality. Between 2000 and 2002, 3415 adults with CAP admitted to 6 hospitals in Edmonton, Alberta, Canada, were prospectively enrolled in a population-based cohort. At the time of hospital admission, demographic, clinical, and laboratory data were collected and the PSI was calculated for each patient. Postdischarge outcomes through to 2006 were ascertained using multiple linked administrative databases. Outcomes included all-cause mortality, hospital admissions, and re-hospitalization for pneumonia over a maximum of 5.4 years of follow-up. Follow-up data were available for 3284 (96%) patients; 66%were > or =65 years of age, 53% were male, and according to the PSI fully 63% were predicted to have greater than 18% 30-day pneumonia-related mortality (that is, PSI class IV-V). Median follow-up was 3.8 years. The 30-day, 1-year, and end of study mortality rates were 12%, 28%, and 53%, respectively. Overall, 82(19%) patients aged <45 years died compared with 1456 (67%) patients aged > or =65 years (hazard ratio [HR], 5.07; 95% confidence interval [CI], 4.06-6.34). Male patients were more likely to die than female patients during follow-up (971 [56%] vs. 767 [49%], respectively; HR, 1.20; 95% CI, 1.13-1.37). Initial PSI classification predicted not only 30-day mortality, but also long-term postdischarge mortality, with 92 (15%) of PSI class I-II patients dying compared with 616 (82%) PSI class V patients (HR, 11.80; 95% CI, 4.70-14.70). Of 2950 patients who survived the initial CAP hospitalization, 72% were hospitalized again (median, 2 admissions over follow-up) and 16% were re-hospitalized with

    Calcification of the vasculature is associated with cardiovascular disease and death in kidney transplant recipients. A novel functional blood test measures calcification propensity by quantifying the transformation time (T50 ) from primary to secondary calciprotein particles. Accelerated T50 indicates a diminished ability of serum to resist calcification. We measured T50 in 1435 patients 10 weeks after kidney transplantation during 2000-2003 (first era) and 2009-2012 (second era). Aortic pulse wave velocity (APWV) was measured at week 10 and after 1 year in 589 patients from the second era. Accelerated T50 was associated with diabetes, deceased donor, first transplant, rejection, stronger immunosuppression, first era, higher serum phosphate and lower albumin. T50 was not associated with progression of APWV. During a median follow-up of 5.1 years, 283 patients died, 70 from myocardial infarction, cardiac failure or sudden death. In Cox regression models, accelerated T50 was strongly and independently associated with both all-cause and cardiac mortality, low versus high T50 quartile: hazard ratio 1.60 (95% confidence interval [CI] 1.00-2.57), ptrend   = 0.03, and 3.60 (95% CI 1.10-11.83), ptrend   = 0.02, respectively. In conclusion, calcification propensity (T50 ) was strongly associated with all-cause and cardiac mortality of kidney transplant recipients, potentially via a cardiac nonAPWV-related pathway. Whether therapeutic improvement of T50 improves outcome awaits clarification in a randomized trial. PMID:26375609

    Asteroid pairs were split due to fast rotation of a strengthless body. Study them can reveal fundamental principles in asteroid interiors and evolution. We continue our spectroscopic survey of asteroid pairs in the near-IR range (IRTF) and work on completing the spectral coverage in the visible wavelength (SALT, NOT).Our new observations support our previous conclusions (Polishook et al. 2014):1. Primary and secondary members have very similar reflectance spectra supporting the claim that every pair originated from a single progenitor. We measured 2 more pairs that present the same taxonomy (4905-7813, 15107-291188). This increases to 22 the number of asteroid pairs with spectral similarities and supports the claim of a single progenitor for each pair to a significance of over 5 sigma.2. Rotational fission is not a function of the asteroid composition rather the asteroid’s structure. We present new reflectance spectra of S- and C-complex pairs that differ in their composition.3. Some asteroid pairs present spectral parameters that imply a fresh, non-weathered surface. This includes spectral slope, and a deep and wide absorption band at 1 micron. Among these, the asteroid 8306 can now be re-classified as a Q-type asteroid, a common class in the near-Earth environment, but rare in the main belt. 8306 is the 4th Q-type discovered within asteroid pairs (all locate in the main belt).4. A secondary member of an asteroid pair composed of ordinary chondrite (S-complex) might present a reflectance spectrum with lower spectral slope compared to its primary member. This is seen in the new measured reflectance spectrum of secondary 291188). This result supports the theory of Jacobson & Scheeres (2011) of continuous disintegration of the secondaries while still in the vicinity of their primaries.5. With time, the fresh surface becomes weathered. Dynamical calculations limit the disintegration time of the progenitor of the pair 4905-7813 to 1.65 millions years ago, what makes

    The majority of the 17 million women globally that are estimated to be infected with HIV live in Sub-Saharan Africa. Worldwide, HIV-related causes contributed to 19 000-56 000 maternal deaths in 2011 (6%-20% of maternal deaths). HIV-infected pregnant women have two to 10 times the risk of dying during pregnancy and the postpartum period compared with uninfected pregnant women. Many of these deaths can be prevented with the implementation of high-quality obstetric care, prevention and treatment of common co-infections, and treatment of HIV with ART. The paper summarizes what is known about HIV disease progression in pregnancy, specific causes of HIV-related maternal deaths, and the potential impact of treatment with antiretroviral therapy on maternal mortality. Recommendations are proposed for improving maternal health and decreasing maternal mortality among HIV-infected women based on existing evidence.

    Background Although epidemiologic studies have shown associations between sedentary behavior and mortality, few have focused on older women with adequate minority representation and few have controlled for both physical activity and functional status. Purpose The objective of this study was to determine the relationship between sedentary time and total; cardiovascular disease (CVD); coronary heart disease (CHD); and cancer mortality in a prospective, multiethnic cohort of postmenopausal women. Methods The study population included 92,234 women aged 50–79 years at baseline (1993–1998) who participated in the Women’s Health Initiative Observational Study through September 2010. Self-reported sedentary time was assessed by questionnaire and examined in 4 categories (≤4, >4–8, ≥8–11, >11 hours). Mortality risks were examined using Cox proportional hazard models adjusting for confounders. Models were also stratified by age, race/ethnicity, body mass index, physical activity, physical function, and chronic disease to examine possible effect modification. Analyses were conducted in 2012–2013. Results The mean follow-up period was 12 years. Compared with women who reported the least sedentary time, women reporting the highest sedentary time had increased risk of all-cause mortality in the multivariate model (HR=1.12, 95% CI=1.05, 1.21). Results comparing the highest versus lowest categories for CVD, CHD, and cancer mortality were as follows: HR=1.13, 95% CI=0.99, 1.29; HR=1.27, 95% CI=1.04, 1.55; and HR=1.21, 95% CI=1.07, 1.37, respectively. For all mortality outcomes, there were significant linear tests for trend. Conclusions There was a linear relationship between greater amounts of sedentary time and mortality risk after controlling for multiple potential confounders. PMID:24439345

    Introduction Five hundred thousand maternal deaths occur each year worldwide, many of which are in developing countries. The maternal mortality rate is a measure that demonstrates the degree of adequacy of prenatal care and of economic and social conditions. The aim of this study was to determine the frequency and causes of pregnancy-related mortality rates in Yazd Province. Methods This cross-sectional study examined the maternal deaths related to pregnancy that were recorded in Yazd Province, Iran, from 2002 to 2011. All maternal deaths that occurred during pregnancy, during delivery, and 42 days after birth were analyzed in this study. The data were collected through a questionnaire, and both direct and indirect causes of maternal deaths were determined. Results Forty pregnancy-related deaths occurred in this period, and the maternal mortality rate was 20.8 deaths per 100,000 live births. The mean age of death in the mothers in this study was 29.17. Fifty-five percent of women of the women who died delivered their babies by cesarean section, and only 20% of them delivered their babies vaginally. Bleeding was the most common cause of maternal mortality (30%), and it was associated directly with maternal mortality. Furthermore 20% of the mothers died due to heart disease and cardiac complications, which were associated indirectly with maternal mortality. Conclusion Cesarean section and its complications were the main cause of death in many cases. Thus, providing a strategic plan to reduce the use of this procedure, educate mothers, and ensure adequate access to pre-maternal care and to care during pregnancy are the most important measures that can be taken to decrease the maternal mortality rate.

    Clearest-Ever Evidence from VLT Spectra of Powerful Event Summary A very bright burst of gamma-rays was observed on March 29, 2003 by NASA's High Energy Transient Explorer (HETE-II) , in a sky region within the constellation Leo. Within 90 min, a new, very bright light source (the "optical afterglow") was detected in the same direction by means of a 40-inch telescope at the Siding Spring Observatory (Australia) and also in Japan. The gamma-ray burst was designated GRB 030329 , according to the date. And within 24 hours, a first, very detailed spectrum of this new object was obtained by the UVES high-dispersion spectrograph on the 8.2-m VLT KUEYEN telescope at the ESO Paranal Observatory (Chile). It allowed to determine the distance as about 2,650 million light-years (redshift 0.1685). Continued observations with the FORS1 and FORS2 multi-mode instruments on the VLT during the following month allowed an international team of astronomers [1] to document in unprecedented detail the changes in the spectrum of the optical afterglow of this gamma-ray burst . Their detailed report appears in the June 19 issue of the research journal "Nature". The spectra show the gradual and clear emergence of a supernova spectrum of the most energetic class known, a "hypernova" . This is caused by the explosion of a very heavy star - presumably over 25 times heavier than the Sun. The measured expansion velocity (in excess of 30,000 km/sec) and the total energy released were exceptionally high, even within the elect hypernova class. From a comparison with more nearby hypernovae, the astronomers are able to fix with good accuracy the moment of the stellar explosion. It turns out to be within an interval of plus/minus two days of the gamma-ray burst. This unique conclusion provides compelling evidence that the two events are directly connected. These observations therefore indicate a common physical process behind the hypernova explosion and the associated emission of strong gamma

    Objective Research on early life socioeconomic status (SES), education and mortality is less established in developing countries. This analysis aims to determine how SES and education are patterned across the life course and associated with adult mortality in Mexico. Materials and methods Data comes from 2001-2012 Mexican Health & Aging Study (Mexican adults age 50+, n=11 222). Cox proportional hazard models predict mortality using baseline covariates Results In unadjusted analyses, similar mortality was seen across levels of early life SES. Lower early life SES was associated with better survival after accounting for education in the younger cohort. Lower education was only associated with mortality in the younger cohort. Conclusions Early life SES was associated with education but the relationship between education and mortality differed across cohorts in Mexico. Selective survival and differential returns to education may explain differences. PMID:26172234

    BACKGROUND: The trend in cervical cancer mortality in Spain from 1951 to 1991 is examined. METHODS: Analysis of national mortality statistics calculating age standardised mortality rates and an age-period cohort analysis. A fit to the Gompertz function was made to estimate the influence of the environmental factors on the mortality rates evolution. MAIN RESULTS: The age standardised mortality rate in Spain is lower than in other developed countries (USA or Estonia) and equal to Norwegian and Finland rates; but whereas in these countries the trend is to decrease, the Spanish rate has increased during this period, because of a cohort effect. A misclassification bias could be responsible for the trend in women aged 40 and older but the increasing trend in younger women could not be interpreted as espurious. The Gompertzian analysis suggests an increase in environmental factors causing cervical cancer. CONCLUSIONS: Cervical cancer mortality rates are increasing in Spain because of environmental factors.   PMID:10492733

    Few studies have examined both the relative magnitude of association and the discriminative capability of multiple indicators of obesity with cardiovascular disease (CVD) mortality risk. We conducted an individual-participant meta-analysis of nine cohort studies of men and women drawn from the British general population resulting in sample of 82 864 individuals. Body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) were measured directly. There were 6641 deaths (1998 CVD) during a mean of 8.1 years of follow-up. After adjustment, a one SD higher in WHR and WC was related to a higher risk of CVD mortality (hazard ratio [95% CI]): 1.15 (1.05-1.25) and 1.15 (1.04-1.27), respectively. The risk of CVD mortality also increased linearly across quintiles of both these abdominal obesity markers with a 66% increased risk in the highest quintile of WHR. In age- and sex-adjusted models only, BMI was related to CVD mortality but not in any other analyses. No major differences were revealed in the discrimination capabilities of models with BMI, WC or WHR for cardiovascular or total mortality outcomes. In conclusion, measures of abdominal adiposity, but not BMI, were related to an increased risk of CVD mortality. No difference was observed in discrimination capacities between adiposity markers.

  9. Current therapies and mortality in acromegaly

    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 GH<1 μg/ L. For the patients with hypersecreting postoperative remnant tumor, those with low chance of surgical cure or with life-threatening comorbidities, medical therapies are available: somatostatin receptor analogues (SRA), dopamine agonists (DA) and GH receptor antagonists. Studies with >30% 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. Conclusion. 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.

    Introduction Smoking is the main preventable cause of death worldwide. The World Health Organization estimates that smoking causes 5 million deaths annually, a figure that could double shortly if the present trend in tobacco product consumption continues. Objectives Estimate smoking-attributable mortality in the Cuban population and provide information needed to carry out effective public health actions. Methods This is a descriptive study using smoking prevalence and mortality data in Cuba for 1995 and 2007. Causes of death were grouped in three categories: malignant tumors, cardiovascular diseases and chronic respiratory diseases. Etiological fractions and attributable mortality were calculated by cause and sex. Results Of deaths recorded in 1995 and 2007, 15% and 18% of preventable deaths were attributed to smoking, respectively. In Cuba in 2007, smoking caused 86% of deaths from lung cancer, 78% of deaths from chronic obstructive pulmonary disease, 28% of deaths from ischemic heart disease, and 26% of deaths from cerebrovascular disease. Conclusions Smoking is responsible for high rates of preventable mortality in Cuba. There is willingness on the part of administrative and political authorities to discourage smoking, and more than half of smokers in Cuba wish to quit smoking. Given awareness that reducing smoking is the most effective means of decreasing preventable morbidity and mortality, the country is moving steadily toward concrete, sustainable steps leading to increased life expectancy and quality of life for the Cuban population.

    OBJECTIVE To analyze cervical and breast cancer mortality in Brazil according to socioeconomic and welfare indicators. METHODS Data on breast and cervical cancer mortality covering a 30-year period (1980-2010) were analyzed. The data were obtained from the National Mortality Database, population data from the Brazilian Institute of Geography and Statistics database, and socioeconomic and welfare information from the Institute of Applied Economic Research. Moving averages were calculated, disaggregated by capital city and municipality. The annual percent change in mortality rates was estimated by segmented linear regression using the joinpoint method. Pearson’s correlation coefficients were conducted between average mortality rate at the end of the three-year period and selected indicators in the state capital and each Brazilian state. RESULTS There was a decline in cervical cancer mortality rates throughout the period studied, except in municipalities outside of the capitals in the North and Northeast. There was a decrease in breast cancer mortality in the capitals from the end of the 1990s onwards. Favorable socioeconomic indicators were inversely correlated with cervical cancer mortality. A strong direct correlation was found with favorable indicators and an inverse correlation with fertility rate and breast cancer mortality in inner cities. CONCLUSIONS There is an ongoing dynamic process of increased risk of cervical and breast cancer and attenuation of mortality because of increased, albeit unequal, access to and provision of screening, diagnosis and treatment.  PMID:25119941

    A study of neonatal mortality in Meerut district revealed an infant mortality rate of 50.1 per 1000 live births. Neonatal mortality accounted for 37.8% of infant mortality with a neonatal mortality rate of 19.0 per 1000 live births. 90.5% of these neonates were delivered at home largely by untrained personnel (57.2%). Only 28.6% of these neonates were treated by qualified doctors and only 30.9% of their mothers were fully immunized against tetanus. At least 2/3rd of neonatal mortality was due to exogenous factors with tetanus neonatorum and septicaemia being the principal causes of mortality each accounting for a mortality rate of 4.7 per 1000 live births.

    local waves. Better earthquake-hazard maps, based on improved knowledge of regional geology, fault behavior, and earthquake mechanisms, are needed for the entire country. Their preparation will require the close collaboration of engineers, seismologists, and geologists. Geologic maps of all inhabited places in earthquake-prone parts of the country are also needed by city planners and others, because the direct relationship between local geology and potential earthquake damage is now well understood. Improved and enlarged nets of earthquake-sensing instruments, sited in relation to known geology, are needed, as are many more geodetic and hydrographic measurements. Every large earthquake, wherever located, should be regarded as a full-scale laboratory experiment whose study can give scientific and engineering information unobtainable from any other source. Plans must be made before the event to insure staffing, funding, and coordination of effort for the scientific and engineering study of future earthquakes. Advice of earth scientists and engineers should be used in the decision-making processes involved in reconstruction after any future disastrous earthquake, as was done after the Alaska earthquake. The volume closes with a selected bibliography and a comprehensive index to the entire series of U.S. Geological Survey Professional Papers 541-546. This is the last in a series of six reports that the U.S. Geological Survey published on the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the March 27, 1964, Magnitude 9.2 Great Alaska Earthquake and extended, as detailed investigations, through several field seasons. The 1964 Great Alaska earthquake was the largest earthquake in the U.S. since 1700. Professional Paper 546, in 1 part, describes Lessons and Conclusions.

    Cycloplegic refraction of 1-year-old children is technically possible and is acceptable to mothers as a method for screening children for visual defects. The range of refractions found in a sample of 186 1-year-old children is reported. Prediction of which children are significantly at risk for squint and/or amblyopia is possible on the basis of refractions at age 1 year according to the criteria selected for an 'abnormal' refraction. Bilateral hypermetropia and/or astigmatism or anisometropia at age 1 year was significantly (P less than 1 in 10 000) associated with a child eventually being found to have squint or amblyopia. Both the age of screening and criteria of abnormality will probably need modification. +2.50 or more D hypermetropia in any one meridian of either eye at age 1 year was even more significantly (P = 0.000 000 05%) associated with squint and/or amblyopia. The possibility that meridional hypermetropia could be the basic defect in squint and amblyopia is discussed. PMID:435441

    The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery is widely used to assess neurocognitive outcomes following sports-related concussion. The purpose of this study was to examine the 1 year test-retest reliability of ImPACT in a multilingual sample of professional hockey players. A total of 305 professional hockey players were tested 1 year apart using ImPACT. Reliable change confidence intervals were calculated and test-retest reliability was measured using Pearson and Intraclass correlation coefficients. Results indicated that the 1-year test-retest reliabilities for the Visual Motor and Reaction Time Composites ranged from low to high (.52 to .81). In contrast, 1-year test-retest reliabilities for the Verbal and Visual Memory Composites were low (.22 to .58). The 1-year test-retest results provided mixed support for the use of Visual Motor and Reaction Time Composites in select samples; in contrast, the Verbal and Visual Memory Composites may not be sensitive to clinical change.

    Background: This study aimed to determine the relationship between the environmental factor, clinical risk factors, and individual variables with mortality due to acute myocardial infarction (MI) in Isfahan. Materials and Methods: This cross-sectional study was performed between April 2012 and March 2013. The data on the patients’ mortality due to MI in Isfahan were obtained from the MI National Registry. The international classification system (ICD10: I21-I22) was used to diagnose MI. The air quality indicators and environmental variables were used to measure the air pollution. Multilevel logistic regression in the Stata software was used to determine the factors associated with mortality in patients and odds ratios (ORs) were calculated. Results: Six hundred eleven patients with MI were studied during 1-year. 444 (72.2%) patients were male and the rest were female. 4.7% of the patients died due to MI. The mean age at MI incidence was 62.2 ± 13 years. Of the air pollution parameters, PM10 had the maximum mean concentration (49.113 ppm), followed by NOX, NO, NO2, CO, SO2, and O3. The adjusted OR of mortality was derived 2.07 (95% CI: 1.5-2.85) for right bundle branch block, 1.5 (95% CI: 1.3-1.7) for ST-segment elevation MI, 1.84 (95% CI: 1.13-3) for age, 1.06 (95% CI: 1.01-1.20) for CO, 1.1 (95% CI: 1.03-1.30) for O3, and 1.04 (95% CI: 1.01-1.4) for SO2, all of which were considered as the risk factors of mortality. However, OR of mortality was 0.79 for precipitation (95% CI: 0.74-0.84) and 0.52 for angioplasty (95% CI: 0.4-0.68) were considered as protective factors of mortality. The individual characteristics including age, history of MI in the immediate family, hypertension, and diabetes were significantly associated with mortality from MI. The indices of air pollution including SO2, CO, O3, and environmental factors such as the precipitation and temperature were the determinants of mortality in patients with MI. Conclusion: With regards to the factors

    With cervical cancer screening the choice of 1-year as a period of follow-up in positive high-risk HPV women without cytological lesions is still under discussion. We evaluated the management of these women and the role of HPV genotyping test. We did a cervical cancer screening study of women aged 35-64 with primary high-risk HPV test. Women positive for high-risk HPV with negative cytology were followed-up after 1 year. In this study we selected women with high-risk HPV+/PapTest- resulted high-risk HPV+ at recall and performed the PapTest and HPV genotyping test. The detection rate of squamous high grade (CIN2+) relative to the total screened cohort was 2.1‰, and it was 0.2‰ at the 1-year recall. The colposcopy performed in women referred at the 1-year recall accounted for 48.8% of the total (baseline + 1-year recall), and 84.3% of these women had no cytological lesions. The most frequent hr-HPV genotype detected was HPV16 and 66.7% of co-infections were due to HPV16 and HPV18. 54.5% of women presented a persistent infection at 1-year recall with the same HPV subtype, 50% of persistent infections was due to HPV16 and 16.7% of these were determined to be CIN2+ histological lesions. Our data show that it may be useful to extend the period of follow-up for women hr-HPV+/PapTest- so as to reduce the number of unnecessary colposcopies due to the transitory infections and that the genotyping test could help to identify the persistent infections in which HPV16 is involved.

    Objectives: To examine all accident and emergency (A&E) department attendances by children under the age of 1 year over a period of 12 months. Also to try to identify the prevalence and severity of accident types in small children and to suggest ways to reduce such accidents. Methods: The A&E department of the Royal Aberdeen Children's Hospital (RACH) serves a population of over half a million. All children under 1 year of age attending this department in the year 2000 had their case notes reviewed by the author and the cause, type, and severity of the illness or injury noted. Results: During the 12 month audit period 1416 new cases under the age of 1 year presented to RACH, 790 of which presented directly to A&E. Six hundred and eighteen (78%) were self referred and 116 children attended A&E on more than one occasion during the year. Four hundred and thirty four (55%) of the A&E attendances were classed as "accidents", the remainder were mainly for medical conditions such as respiratory distress. Two hundred and sixty four (61%) were caused by falls and 38% were admitted for inpatient management. Two hundred and twenty nine (29%) required radiographs, which revealed 30 fractures. Thirty seven children sustained scalds/burns and there were 33 accidental ingestions. Six cases were judged to be non-accidental. Conclusions: There is a surprisingly high rate of "accidental" injury in this age group, bringing into question the effectiveness of current accident prevention strategies. Perhaps specific prevention advice should be targeted at parents and carers of young children. There should always be a high index of suspicion for non-accidental injury. PMID:12533361

    2010-01-01

    Background Shoulder pain is a common complaint in primary health care and has an unfavourable outcome in many patients. The objectives were to identify predictors for pain and disability (SPADI) and work status in patients with subacromial shoulder pain. Methods Secondary analyses of data from a randomized clinical controlled trial were performed. Outcome measures were the absolute values of the combined Shoulder Pain and Disability Index (SPADI) and work status 1 year after treatment with supervised exercises (SE) or radial extracorporeal shockwave therapy (rESWT). Predictors of outcome were investigated using multiple linear regression (SPADI) and logistic regression (work status). Results 104 patients were included. Low education (≤ 12 years), previous shoulder pain, and a high baseline SPADI score predicted poor results with these variables explaining 29.9% of the variance in SPADI score at 1 year. Low education and poor self-reported health status predicted a work status of "not working": Odds Ratio, OR = 4.3(95% CI (1.3 to 14.9)), p = 0.02 for education, and OR = 1.06 (95% CI (1.0 to 1.1)), p = 0.001 for self-reported health status, respectively. Adjustments for age, gender, and treatment group were performed, but did not change the results. Conclusion Education was the most consistent predictor of pain and disability, and work status at 1 year follow-up. Also, baseline SPADI score, previous shoulder pain and self-reported health status predicted outcome. Trial registration Clinical trials NCT00653081 PMID:20863369

    Background We have shown that a fourth-generation telehealth program that analyzes and responds synchronously to data transferred from patients is associated with fewer hospitalizations and lower medical costs. Whether a fourth-generation telehealth program can reduce all-cause mortality has not yet been reported for patients with chronic cardiovascular disease. Objective We conducted a clinical epidemiology study retrospectively to determine whether a fourth-generation telehealth program can reduce all-cause mortality for patients with chronic cardiovascular disease. Methods We enrolled 576 patients who had joined a telehealth program and compared them with 1178 control patients. A Cox proportional hazards model was fitted to analyze the impact of risk predictors on all-cause mortality. The model adjusted for age, sex, and chronic comorbidities. Results There were 53 (9.3%) deaths in the telehealth group and 136 (11.54%) deaths in the control group. We found that the telehealth program violated the proportional hazards assumption by the Schoenfeld residual test. Thus, we fitted a Cox regression model with time-varying covariates. The results showed an estimated hazard ratio (HR) of 0.866 (95% CI 0.837-0.896, P<.001; number needed to treat at 1 year=55.6, 95% CI 43.2-75.7 based on HR of telehealth program) for the telehealth program on all-cause mortality after adjusting for age, sex, and comorbidities. The time-varying interaction term in this analysis showed that the beneficial effect of telehealth would increase over time. Conclusions The results suggest that our fourth-generation telehealth program is associated with less all-cause mortality compared with usual care after adjusting for chronic comorbidities.

    Abstract Whilst survival rates for childhood cancers are excellent, it is known that these patients have an increased risk of death from disease recurrence and other causes. We investigate patterns, trends and survival of cancers in children and young adults in N. Ireland. Materials and Methods 21 years (1993-2013) of cancer incidence data including non-malignant brain tumours from the N. Ireland Cancer Registry for persons aged 0-24 years was analysed using Joinpoint regresssion for trend and the Kaplan Meier method for survival analysis up to end 2013 with excess mortality calculated at one and five years after first cancer diagnosis using standardised mortality ratios. Results 2633 children and young people were diagnosed with cancer, 1386 (52.6%) male and 1247 female with 1139 (43.3%) aged 0-14. While trends increased over time they did not reach statistical significance except in the 15-24 age group for males and females combined. The most common cancers for age 0-14 were brain, eye and central nervous system and leukaemia with skin (including non-melanoma skin) the most common in the 15-24 age group. 59 patients (2.2%) had a record of a second cancer. Survival was high at 90.7% after 1 year, better among females and similar for older and younger groups. Although mortality in children is low overall, there was an excess mortality 24.7% (22-27.5) p<0.001 at one year and 7.3% (5.5-9.2) p<0.001 for those who survived 5 years. Excluding the primary cancer there was an excess mortality for one year survivors, with deaths twice that of the background level (SMR= 2.2 (1.3-3.0)p=0.005 and although one and a half times background levels at 5 years, the excess mortality was not significant 1.5 (0.6-2.3 p=0.269). Conclusion Whilst survival from childhood cancers is excellent, this work in common with larger studies, highlights the need for ongoing monitoring of cancer survivors. Preventable skin cancer was identified as a problem in young adults.

  4. Testosterone and mortality.

    Muraleedharan, Vakkat; Jones, T Hugh

    2014-10-01

    Epidemiological studies have found that men with low or low normal endogenous testosterone are at an increased risk of mortality than those with higher levels. Cardiovascular disease accounts for the greater proportion of deaths in those with low testosterone. Cancer and respiratory deaths in some of the studies are also significantly more prevalent. Disease-specific studies have identified that there are higher mortality rates in men with cardiovascular, respiratory and renal diseases, type 2 diabetes and cancer with low testosterone. Obesity, metabolic syndrome, type 2 diabetes, cardiovascular disease and inflammatory disorders are all associated with an increased prevalence of testosterone deficiency. Two major questions that arise from these findings are (1) is testosterone deficiency directly involved in the pathogenesis of these conditions and/or a contributory factor impairing the body's natural defences or is it merely a biomarker of ill health and the severity of underlying disease process? (2) Does testosterone replacement therapy retard disease progression and ultimately enhance the clinical prognosis and survival? This review will discuss the current state of knowledge and discuss whether or not there are any answers to either of these questions. There is convincing evidence that low testosterone is a biomarker for disease severity and mortality. Testosterone deficiency is associated with adverse effects on certain cardiovascular risk factors that when combined could potentially promote atherosclerosis. The issue of whether or not testosterone replacement therapy improves outcomes is controversial. Two retrospective studies in men with diagnosed hypogonadism with or without type 2 diabetes have reported significantly improved survival. PMID:25041142

    We analyzed the outcomes of patients who survived disease-free for 1-year or more following second allogeneic hematopoietic cell transplantation (HCT) for relapsed acute leukemia or myelodysplastic syndromes between 1980 and 2009. A total of 1285 patients received a second allogeneic transplant following disease relapse; among these 325 survived relapse-free at 1-year after the second HCT. The median time from first to second HCT was 17 and 24 months for children and adults, respectively. A myeloablative preparative regimen was used in the second transplant in 62% of children and 45% of adult patients. The overall 10-year conditional survival rates after second transplantation in this cohort of patients who had survived disease-free for at least one year were 55% in children and 39% in adults. Relapse was the leading cause of mortality (77% and 54% of deaths in children and adults, respectively). In multivariate analyses, only disease status prior to second HCT was significantly associated with higher risk for overall mortality (HR 1.71 for patients with disease not in complete remission prior to second HCT, P<0.01). Chronic graft-versus-host disease (GVHD) developed in 43% and 75% of children and adults following second transplant. Chronic GVHD was the leading cause of non-relapse mortality followed by organ failure and infection. The cumulative incidence of developing at least one of the studied late effects at 10-years after second HCT was 63% in children and 55% in adults. The most frequent late effects in children were growth disturbance (10-year cumulative incidence 22%) and cataracts (20%), and in adults were cataracts (20%) and avascular necrosis (13%). Among patients with acute leukemia and myelodysplastic syndromes who receive a second allogeneic HCT for relapse and survive disease-free for at least 1-year, many can be expected to survive long term. However, they continue to be at risk for relapse and non-relapse morbidity and mortality. Novel approaches

    Background High body mass index (BMI) is paradoxically associated with better outcomes in hemodialysis (HD) patients. This study aimed to examine whether serum creatinine (Cr), a marker of muscle mass, could modify the association between BMI, and mortality and morbidity in prevalent HD patients. Methods A retrospective study was conducted using a nationwide database from the registry of the Japanese Society for Dialysis Therapy. A total of 119,099 patients were selected (age: 65±12 years; median time on HD: 5.6 years; male: 62%), and we examined the association of basal BMI with mortality and morbidity after a 1-year period. Patients were stratified either by BMI into 4 groups or by serum Cr levels into 3 tertiles. Odds ratio (OR) [95% confidence interval] was calculated by multivariate logistic regression analysis. Results Higher BMI did not predict a higher 1-year total mortality. However, when we stratified the patients by serum Cr levels, the risk of cardiac death became significantly higher in obese patients with the lowest Cr levels, in both males (OR 2.82 [1.51–5.27], p<0.01) and females (OR 2.00 [1.03–3.90], p<0.05). The risk of new cerebral infarction was also higher in obese male patients within the lowest Cr tertile. In contrast, there was a significantly lower risk of cardiac, cerebrovascular, and infection-related death in non-obese patients with higher levels of Cr. Higher serum Cr was also related to a lower risk of cardiovascular events and hip fracture in non-obese HD patients. Conclusions The obesity paradox was found to be present in HD patients only when obesity was defined by BMI. Decreased serum Cr levels were found to be positively associated with clinical poor outcomes in all BMI groups. Thus, irrespective of BMI, the evaluation of serum Cr levels is important to predict mortality and morbidity in patients receiving regular HD. PMID:26930325

    Objectives: There is limited cross-national research on youth mortality. 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. Youth aged 25-34 in Russia and South Africa had, respectively, 10 and 29 times higher mortality than their counterparts in Hong Kong. United States (US) had the 12th highest mortality rate among youth aged 15-24 and the 13th highest rate among youth aged 25-34. Overall, the US youth had 2-3 times higher rates of mortality than their counterparts in many industrialized countries including Hong Kong, Singapore, Netherlands, Switzerland, Germany, Norway, and Sweden. Income inequality, unemployment rate, and human development explained 50-66% of the global variance in youth mortality. Compared to the countries with low unemployment and income inequality and high human development levels, countries with high unemployment and income inequality and low human development had, respectively, 343%, 213%, and 205% higher risks of youth mortality. Conclusions and Global Health Implications: Marked international disparities in

    Abstract Objective. The majority of patients with schizophrenia have cognitive deficits early in the disease. We evaluated the relationship between cognitive function, social functioning and quality of life in patients with first-episode psychosis. Methods. This was a longitudinal study in 15 patients aged 18-30 years who had recently experienced a first psychotic episode and were treated with the atypical antipsychotic aripiprazole, cognitive-behavioural therapy, psycho-educational sessions, family supportive sessions and social interventions. Patients were evaluated at baseline and after 1 year. Cognitive assessment included attention, memory, language skills and problem solving. Social functioning, quality of life, and psychopathological evaluation were performed with validated tools. Results. At baseline, patients had a severe impairment of social functioning and a low quality of life, while a specific pattern of cognitive functions was not identified. After 1-year, we observed a significant improvement in social functioning and quality of life, without a significant decrease in cognitive function. Conclusion. Contrary to previous findings, we found that social functioning and quality of life are related, but independent of cognitive impairment. The use of antipsychotic agents that do not interefere with cognitive function plus psychological assistance is a valuable treatment approach in patients with first-episode schizophrenia.

    Introduction. To evaluate outcomes of wide-diameter (6 mm) implants immediately provisionalized with cement-retained single crowns in posterior molar sites. Materials and Methods. Forty-eight consecutive patients received a total of 53 moderately rough-surface, 6 mm diameter implants in healed sites. All implants were immediately provisionalized with a cement-retained provisional crown. Final prosthesis with cement-retained porcelain fused to metal crowns was delivered 3-6 months later. Patients were followed up for 1 year. Outcome measures were implant failures and success rate, complications, marginal bone levels, bone level changes, papilla index, bleeding on probing, and inflammation. Results. One patient was lost to follow-up. At one year, the implant survival and success rate were 98.1%. The mean marginal bone loss after 1 year was -0.17 ± 1.84 mm. Ideal papilla score was recorded at 83.8% of the sites. More than 95.6% of the sites showed no bleeding or inflammation. No procedure-related or device-related adverse events were reported. Conclusion. Wide-diameter (6 mm) implants can safely and successfully replace single posterior molars. Longer follow-up studies are necessary to evaluate the long-term success of these implants.

    Background Giant cell arteritis (GCA) is a systemic vasculitis of elderly individuals associated with significant morbidity, including blindness, stroke, and myocardial infarction. Previous studies have investigated whether GCA is associated with increased mortality, with conflicting results. The objective of this study is to determine whether GCA, is associated with increased mortality. Methods Forty-four cases with GCA were identified from the University of Utah Health Sciences Center, the major tertiary care center for the Intermountain West. The Utah Population Database, a unique biomedical information resource, selected cases and age- and gender-matched controls. Cases were defined as patients with a temporal artery biopsy-proven diagnosis of GCA (international classification of diseases [ICD]-9 code 446.5) between 1991 and 2005. Exclusion criteria included a negative biopsy, alternative diagnoses, or insufficient clinical data. For each of the 44 cases, 100 controls were identified; thus, 4,400 controls were included in the data analysis. Median survival time and 5-year cumulative survival were measured for cases and controls. Results The median survival time for the 44 GCA cases was 1,357 days (3.71 years) after diagnosis compared with 3,044 days (8.34 years) for the 4,400 controls (p = 0.04). Five-year cumulative survival was 67% for the control group versus 35% for the cases (p < .001). Survival rates for cases and controls converged at approximately 11.12 years. Conclusions Patients with GCA were more likely than age- and gender-matched controls to die within the first 5 years following diagnosis. PMID:19196636

    Episodic tree mortality events, such as those caused by insect outbreaks, are often characterized by aggregated tree mortality, resulting in patches of dead trees. However, simultaneously with mortality within these aggregates, individual tree mortality in the surrounding forest matrix can also be considerable. Consequences of this diffuse mortality for stand structure and further development differ from that of aggregated mortality. Here, we used change detection in LANDSAT-images and a stand-level field inventory in a naturally dynamic forest landscape in Arkhangelsk province in Russia, to examine the role of spatially diffuse mortality during an episodic tree mortality event, caused by drought and bark beetles. We show that even if patches of dead trees are a prominent and visible feature within the study landscape, diffuse mortality outside of these distinct patches was responsible for a large proportion of tree deaths. The findings demonstrate the potential importance of spatially diffuse tree mortality and the consequent finer scale forest dynamics even during episodic events.

    OBJECTIVE--To examine the relation between health outcomes and the equality with which income is distributed in the United States. DESIGN--The degree of income inequality, defined as the percentage of total household income received by the less well off 50% of households, and changes in income inequality were calculated for the 50 states in 1980 and 1990. These measures were then examined in relation to all cause mortality adjusted for age for each state, age specific deaths, changes in mortalities, and other health outcomes and potential pathways for 1980, 1990, and 1989-91. MAIN OUTCOME MEASURE--Age adjusted mortality from all causes. RESULTS--There was a significant correlation (r = -0.62 [corrected], P < 0.001) between the percentage of total household income received by the less well off 50% in each state and all cause mortality, unaffected by adjustment for state median incomes. Income inequality was also significantly associated with age specific mortalities and rates of low birth weight, homicide, violent crime, work disability, expenditures on medical care and police protection, smoking, and sedentary activity. Rates of unemployment, imprisonment, recipients of income assistance and food stamps, lack of medical insurance, and educational outcomes were also worse as income inequality increased. Income inequality was also associated with mortality trends, and there was a suggestion of an impact of inequality trends on mortality trends. CONCLUSION--Variations between states in the inequality of the distribution of income are significantly associated with variations between states in a large number of health outcomes and social indicators and with mortality trends. These differences parallel relative investments in human and social capital. Economic policies that influence income and wealth inequality may have an important impact on the health of countries.

    Mechanical circulatory support devices have been increasingly used for long-term support. We reviewed outcomes in all patients supported with a SynCardia total artificial heart (TAH) for more than 1 year to assess its safety in long-term support. As of December 2011, all 47 patients who received the TAH from 10 centers worldwide were included in this retrospective study. Clinical data were collected on survival, infections, thromboembolic and hemorrhagic events, device failures, and antithrombotic therapy. The mean age of patients was 50 ± 1.57 years, the median support time was 554 days (range 365-1373 days). The primary diagnosis was dilated cardiomiopathy in 23 patients, ischemic in 15, and "other" in 9. After a minimum of 1 year of support, 34 patients (72%) were successfully transplanted, 12 patients (24%) died while on device support, and 1 patient (2%) is still supported. Five patients (10%) had a device failure reported. Major complications were as follows: systemic infections in 25 patients (53%), driveline infections in 13 patients (27%), thromboembolic events in 9 patients (19%), and hemorrhagic events in 7 patients (14%). SynCardia TAH has proven to be a reliable and effective device in replacing the entire heart. In patients who reached a minimum of 1 year of support, device failure rate is acceptable and only in two cases was the leading cause of death. Infections and hemorrhagic events were the major causes of death. Patients who remain supported beyond 1 year are still likely to survive to transplantation.

    In general, voluminous data exists concerning burns in children, but the data focusing specially on children less than 1 year of age is sporadic. We therefore focused on examining the special features of burns in children less than 1 year of age. A retrospective study of all outpatient treated burn patients <1 year old at the Hospital for Children and Adolescents, Helsinki, Finland, from January 2005 to December 2009 was performed. During the 5-year period we identified 106 outpatient treated infants with burns, representing 15% of all pediatric burns during the study period. The majority was male and aged 9-12 months. Most of the burns occurred at home, and in most cases a caregiver was present in the injury room. Scalds were the most common type of injury followed by contact burns. The most common source of scald was from cups containing hot drink, and the most common source of contact burn was hot stoves or oven doors. Special attention needs to be targeted toward the prevention of burns in children less than 1 year of age. The majority of the injuries could have been prevented with more vigilance.

    Background Catheter-based sympathetic renal denervation (RDN) is a recent therapeutic option for patients with resistant hypertension. However, the impact of RDN in left ventricular (LV) mass and function is not completely established. Our aim was to evaluate the effects of RDN on LV structure and function (systolic and diastolic) in patients with resistant hypertension (HTN). Methods and Results From a single centre prospective registry including 65 consecutive patients with resistant HTN submitted to RDN between July-2011 and April-2015, 31 patients with baseline and 1-year follow-up echocardiogram were included in this analysis. Mean age was 65±7 years, 48% were males, 71% had type 2 diabetes. Most had hypertension lasting for more than 10 years (90%), and were being treated with a median number of 6 anti-hypertensive drugs, including 74% on spironolactone. At 1-year, there was a significant decrease both on office SBP (176±24 to 149±13mmHg, p<0.001) and DBP (90±14 to 79±11mmHg, p<0.001), and also in 24h ABPM SBP (150±20 to 132±14mmhg, p<0.001) and DBP (83±10 to 74±9mmHg, p<0.001). There was also a significant decrease in LV mass from 152±32 to 136±34g/m2 (p<0.001), an increase in LV end diastolic volume (93±18 to 111±27 mL, p = 0.004), an increase in LV ejection fraction (65±9 to 68±9%, p = 0.001) and mitral valve E deceleration time (225±49 to 247±51ms, p = 0.015) at 1-year follow up. There were no significant changes in left atrium volume index or in the distribution of patients among the different left ventricle geometric patterns and diastolic function subgroups. Conclusions In this single centre registry of patients with resistant hypertension, renal denervation was associated with significant reduction in both office and ABPM blood pressure and a significant decrease in left ventricle mass evaluated by transthoracic echocardiogram at 1 year follow-up.

    Background Inability of heart failure (HF) patients to recognize worsening symptoms that herald an exacerbation is a common reason for HF readmissions. Aims To examine the relationship between patterns of HF symptom variability, and HF event-free survival. Methods Patients with HF (N = 71) rated HF symptoms daily for 30 days. Symptoms were rated on a 10 point scale anchored at the extreme ends by “worst symptom could be” and “best symptom could be”. Patients were followed for an average of 1 year to track HF and cardiac rehospitalizations and all-cause mortality. Results Cox regression comparing event-free survival between patients who had highly variable symptom ratings across the 30-days and those whose symptoms were less variable revealed worse event-free survival in patients with more variable symptoms of shortness of breath or edema. Symptom variability predicted event-free survival independently of severity of symptoms, ejection fraction, comorbidities, age and gender. Symptom severity did not predict rehospitalization or mortality. Conclusion Regardless of symptom severity, patients whose symptoms fluctuated in an improving and worsening pattern were at substantially greater risk for poorer event-free survival. These patients may become accustomed to this pattern such that they expect symptoms to improve and thus do not seek treatment with worsening symptoms. PMID:20637697

    Hematopoietic SCT (HSCT) is a life-saving therapy in children, but has been associated with heart failure. Little is known about subclinical changes in cardiac function. We examined changes in systolic and diastolic function from pre- to 1-year post HSCT by echocardiography. All patients (n=74, 61% men, median age 9.1 years, mean left-ventricular (LV) ejection fraction 61.3±4.9%) who underwent HSCT at Children's Hospital Boston between 2005 and 2008, were <21 years at time of HSCT, and had routine pre- and 1-year post echocardiograms were included. Systolic function parameters, including LV ejection fraction, rate-corrected velocity of fiber shortening (Vcfc) and stress-velocity index and diastolic parameters, including tissue Doppler imaging (TDI)-derived velocities, and left-ventricular flow propagation, were compared before and after transplant. At 1-year post HSCT, systolic function, as measured by Vcfc (1.10±0.15 vs 1.04±0.12 circ/s; P=0.03) and stress-velocity index (z-score 0.40±1.4 vs -0.20±1.1; P=0.02), had worsened; diastolic function parameters, including mitral E' velocity (16.6±3.9 vs 15.0±3.4 cm/s; P=0.01) and tricuspid E' velocity (14.3±3.6 vs 12.4±2.8 cm/s; P=0.002) had also decreased. At 1-year post HSCT, children have subclinical declines in systolic and diastolic function. These small changes might become clinically important over time. Serial non-invasive assessment of cardiac function should be considered in all children following HSCT.

    single-treatment course analysis that ignored the effects of re-treatment, the percentage of UBT-negative results at 1 year was 72.4% (95% CI, 69.9%–74.8%) and was significantly associated with study site (P<.001), adherence to initial therapy (AOR, 0.26; 95% CI, 0.15–0.42; P<.001), male sex (AOR, 1.63; 95% CI, 1.25–2.13; P<.001), and age (AOR, 1.14; 95% CI, 1.02–1.27 per decade; P=.02). One-year effectiveness among all 1463 enrolled participants, considering all missing UBT results as positive, was 72.7% (95% CI, 70.3%–74.9%). Conclusions and Relevance One year after treatment for H pylori infection, recurrence occurred in 11.5% of participants who had negative posttreatment UBT results. Recurrence determinants (ie, nonadherence and demographics) may be as important as specific antibiotic regimen in determining the long-term success of H pylori eradication interventions.

    Objective-To evaluate annual survival and mortality rates and the longevity of a managed population of bottlenose dolphins (Tursiops truncatus). Design-Retrospective cohort study. Animals-103 bottlenose dolphins at the US Navy Marine Mammal Program (MMP). Procedures-Population age structures, annual survival and crude mortality rates, and median age at death for dolphins > 30 days old were determined from 2004 through 2013. Results-During 2004 through 2013, the annual survival rates for MMP dolphins ranged from 0.98 to 1.0, and the annual crude mortality rates ranged from 0% to 5%, with a mean of 2.7%. The median age at death was 30.1 years from 2004 through 2008 and increased to 32 years from 2009 through 2013. The maximum age for a dolphin in the study was 52 years. Conclusions and Clinical Relevance-Results indicated that the annual mortality rates were low and survival rates were high for dolphins in the MMP from 2004 through 2013 and that the median age at death for MMP dolphins during that time was over 10 years greater than that reported in free-ranging dolphins. These findings were likely attributable to the continually improving care and husbandry of managed dolphin populations.

    Over the last century life expectancy has increased substantially and so has the share of health care expenditures financed by governments. In cross-country comparisons, the US, which has the lowest government health expenditure share, often has the poorest health outcomes. Is there a plausible connection between health outcomes and government financing of health care? This paper addresses this question with panel data from 20 developed countries from 1950 to 2010. I review the history of government involvement in health care financing over this period. Then I use panel regression methods to examine whether a variety of mortality based outcome measures are correlated with the extent of government involvement. The answers are robustly negative.

    Background: Few studies have evaluated the relation between selenium supplementation after diagnosis and prostate cancer outcomes. Methods: We prospectively followed 4459 men initially diagnosed with nonmetastatic prostate cancer in the Health Professionals Follow-Up Study from 1988 through 2010 and examined whether selenium supplement use (from selenium-specific supplements and multivitamins) after diagnosis was associated with risk of biochemical recurrence, prostate cancer mortality, and, secondarily, cardiovascular disease mortality and overall mortality, using Cox proportional hazards models. All P values were from two-sided tests. Results: We documented 965 deaths, 226 (23.4%) because of prostate cancer and 267 (27.7%) because of cardiovascular disease, during a median follow-up of 8.9 years. In the biochemical recurrence analysis, we documented 762 recurrences during a median follow-up of 7.8 years. Crude rates per 1000 person-years for prostate cancer death were 5.6 among selenium nonusers and 10.5 among men who consumed 140 or more μg/day. Crude rates per 1000 person-years were 28.2 vs 23.5 for all-cause mortality and 28.4 vs 29.3 for biochemical recurrence, for nonuse vs highest-dose categories, respectively. In multivariable analyses, men who consumed 1 to 24 μg/day, 25 to 139 μg/day, and 140 or more μg/day of supplemental selenium had a 1.18 (95% confidence interval [CI] = 0.73 to 1.91), 1.33 (95% CI = 0.77 to 2.30), and 2.60-fold (95% CI = 1.44 to 4.70) greater risk of prostate cancer mortality compared with nonusers, respectively, P trend = .001. There was no statistically significant association between selenium supplement use and biochemical recurrence, cardiovascular disease mortality, or overall mortality. Conclusion: Selenium supplementation of 140 or more μg/day after diagnosis of nonmetastatic prostate cancer may increase risk of prostate cancer mortality. Caution is warranted regarding usage of such supplements among men with prostate

    Longitudinal studies at the level of individuals find that employees who lose their jobs are at increased risk of death. However, analyses of aggregate data find that as unemployment rates increase during recessions, population mortality actually declines. We addressed this paradox by using data from the US Department of Labor and annual survey data (1979-1997) from a nationally representative longitudinal study of individuals-the Panel Study of Income Dynamics. Using proportional hazards (Cox) regression, we analyzed how the hazard of death depended on 1) individual joblessness and 2) state unemployment rates, as indicators of contextual economic conditions. We found that 1) compared with the employed, for the unemployed the hazard of death was increased by an amount equivalent to 10 extra years of age, and 2) each percentage-point increase in the state unemployment rate reduced the mortality hazard in all individuals by an amount equivalent to a reduction of 1 year of age. Our results provide evidence that 1) joblessness strongly and significantly raises the risk of death among those suffering it, and 2) periods of higher unemployment rates, that is, recessions, are associated with a moderate but significant reduction in the risk of death among the entire population.

    Black patients receiving dialysis for end-stage renal disease in the United States have lower mortality rates than white patients. Whether racial differences exist in mortality after acute renal failure is not known. We studied acute renal failure in patients hospitalized between 2000 and 2003 using the Nationwide Inpatient Sample and found that black patients had an 18% (95% confidence interval [CI] 16 to 21%) lower odds of death than white patients after adjusting for age, sex, comorbidity, and the need for mechanical ventilation. Similarly, among those with acute renal failure requiring dialysis, black patients had a 16% (95% CI 10 to 22%) lower odds of death than white patients. In stratified analyses of patients with acute renal failure, black patients had significantly lower adjusted odds of death than white patients in settings of coronary artery bypass grafting, cardiac catheterization, acute myocardial infarction, congestive heart failure, pneumonia, sepsis, and gastrointestinal hemorrhage. Black patients were more likely than white patients to be treated in hospitals that care for a larger number of patients with acute renal failure, and black patients had lower in-hospital mortality than white patients in all four quartiles of hospital volume. In conclusion, in-hospital mortality is lower for black patients with acute renal failure than white patients. Future studies should assess the reasons for this difference. PMID:17855647

    Background: The purpose of this study was to examine the association of accelerometer-assessed sedentary behavior and residual-specific mortality. Methods: Data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) were used (N = 5536), with follow-up through 2011. Sedentary behavior was objectively measured over 7 days via accelerometry. Results: When expressing sedentary behavior as a 60 min/day increase, the hazard ratio across the models ranged from 1.07-1.40 (P < 0.05). There was evidence of an interaction effect between sedentary behavior and total physical activity on residual-specific mortality (Hazard ratiointeraction [HR] = 0.9989; 95% CI: 0.9982-0.9997; P = 0.008). Conclusion: Sedentary behavior was independently associated with residual-specific mortality. However, there was evidence to suggest that residual-specific mortality risk was a function of sedentary behavior and total physical activity. These findings highlight the need for future work to not only examine the association between sedentary behavior and health independent of total physical activity, but evaluate whether there is a joint effect of these two parameters on health.

    2013-01-01

    Background Health inequities in developing countries are difficult to eradicate because of limited resources. The neglect of adult mortality in Sub-Saharan Africa (SSA) is a particular concern. Advances in data availability, software and analytic methods have created opportunities to address this challenge and tailor interventions to small areas. This study demonstrates how a generic framework can be applied to guide policy interventions to reduce adult mortality in high risk areas. The framework, therefore, incorporates the spatial clustering of adult mortality, estimates the impact of a range of determinants and quantifies the impact of their removal to ensure optimal returns on scarce resources. Methods Data from a national cross-sectional survey in 2007 were used to illustrate the use of the generic framework for SSA and elsewhere. Adult mortality proportions were analyzed at four administrative levels and spatial analyses were used to identify areas with significant excess mortality. An ecological approach was then used to assess the relationship between mortality “hotspots” and various determinants. Population attributable fractions were calculated to quantify the reduction in mortality as a result of targeted removal of high-impact determinants. Results Overall adult mortality rate was 145 per 10,000. Spatial disaggregation identified a highly non-random pattern and 67 significant high risk local municipalities were identified. The most prominent determinants of adult mortality included HIV antenatal sero-prevalence, low SES and lack of formal marital union status. The removal of the most attributable factors, based on local area prevalence, suggest that overall adult mortality could be potentially reduced by ∼90 deaths per 10,000. Conclusions The innovative use of secondary data and advanced epidemiological techniques can be combined in a generic framework to identify and map mortality to the lowest administration level.

    Maternal mortality is an important indicator of adequacy of health care in our society. Improvements in the obstetric care system as well as advances in technology have contributed to reduction in maternal mortality rates. Trauma complicates up to 7% of all pregnancies and has emerged as the leading cause of maternal mortality, becoming a significant concern for the public health system. Maternal mortality secondary to trauma can often be prevented by coordinated medical care, but it is essential that caregivers recognize the unique situation of providing simultaneous care to 2 patients who have a complex physiologic relationship. Optimal management of the pregnant trauma victim requires a multidisciplinary team, where the obstetrician plays a central role. This review focuses on the incidence of maternal mortality due to trauma, the mechanisms involved in traumatic injury, the important anatomic and physiologic changes that may predispose to mortality due to trauma, and finally, preventive strategies that may decrease the incidence of traumatic maternal death.

    Aims: A historical cohort mortality study was conducted among 17 668 members of the Construction Workers' Health Insurance Society of Mie Prefecture in Japan, in order to verify the relation between occupations and mortality status. Methods: The cohort was followed from 2 April 1973 to 1 April 1998. Standardised mortality ratios (SMR) were calculated for all members and each job classification. Results: 98.7% of the members were traced successfully until the date when the follow up terminated. When all members were considered together, significant excess mortality was observed for "accidents and adverse effects". Significant excess mortalities were also observed for lung cancers among scaffold men and ironworkers, for cancer of the oesophagus among plumbers, and for "chronic liver disease and cirrhosis" among scaffold men and painters. Conclusion: Results suggest that more detailed investigations, which would include some minor job classifications should be undertaken. This is an updated cohort study which was partially completed in 1997. PMID:12151606

    We examined the biodiversity of bacteria associated with oyster-shell waste during a 1-year storage period using 16S ribosomal DNA analysis. Temperature variation and structural changes of oyster shell were observed during storage. Initial and final temperatures were at 16-17 degrees C, but a high temperature of about 60 degrees C was recorded after approximately 6 months of storage. The crystal structure and nanograin of the oyster shell surface were sharp and large in size initially and became gradually blunter and smaller over time. Phylogenetic analysis revealed that Firmicutes were dominant in the oyster-shell waste initially, during the high-temperature stage, and after 1 year of storage (making up >65% of the biodiversity at all three sampling times). Bacillus licheniformis was presumed as the predominate Firmicutes present. These bacteria are likely to have important roles in the biodegradation of oyster shell.

    This study tested the hypothesis that an immediate effect of exposure to masked phobic stimuli on avoidance of the corresponding feared object would be maintained 1 year later. Fifty-three spider-phobic participants were identified with a questionnaire and a Behavioral Avoidance Test (BAT) with a live tarantula. One week later, they were administered 1 of 3 types of exposure: very brief (25-ms, masked) or clearly visible (125-ms, unmasked) images of spiders, or very brief images of flowers. They engaged in the BAT again immediately thereafter. One year later, they returned for a follow-up BAT. The immediate effect of exposure to very brief spiders on reducing avoidance of the tarantula was still evident 1 year later. Endurance of an effect by masked stimuli of this duration has not been reported before. Potential theoretical implications are discussed. PMID:23527506

    We used an ELISPOT (enzyme-linked immunosorbent spot) assay to quantitate the long-term rotavirus-specific intestinal antibody response in a murine model. The frequency of murine intestinal antibody-secreting cells (ASCs) was followed for a period of 1 year after a single dose of rhesus rotavirus (10(6) PFU) was administered at 10 days of age. Some animals were boosted at that time with a second dose. One year after infection, virus-specific ASCs declined from acute-phase levels, but they were still present at significant levels (1.32 x 10(4) virus-specific ASCs per 10(6) intestinal mononuclear cells; approximately 17% of the previously reported response at 1 month after infection). A booster dose 1 year after the primary infection produced a 100% increase in virus-specific ASCs but did not restore the response to that of the primary infection. PMID:8381806

    1976 census data and data on births to 8788 ever married women from the 1980 Egyptian Fertility Survey were analyzed to determine if son preference was responsible for higher mortality among girls than among boys and what factors were associated with this higher mortality. During 0-3 years, boys were more likely to die than females. For example, the overall male-female sex ratio for the 1st year was 118:100. At ages 5, 10, 15, and 2 0, however, girls were more likely to die. The sex rations for these years were 98, 95, 93, and 91. In fact, the excess mortality among illiterate mothers accounted for most of the overall excess mortality. As mother's educational level rose, the excess mortality of girls fell, so that by university level boys experienced excess mortality (130, 111, 112, 105). Less educated mothers breast fed sons longer and waited more months after birth of a son to have another child indicating son preference, but these factors did not necessarily contribute to excess mortality. The major cause of female excess mortality in Egypt was that boys received favored treatment of digestive and respiratory illnesses as indicated by accessibility to a pharmacy (p.01). Norms/traditions and religion played a significant role in excess mortality. The effect of norms/traditions was greater than religion, however. Mother's current and past employment strongly contributed to reducing girls' mortality levels (p.01). These results indicated that Egypt should strive to increase the educational level of females and work opportunities for women to reduce female child mortality. Further, it should work to improve women's status which in turn will reduce norms/traditions that encourage son preference and higher mortality level for girls.

    Mortality and survival of white-tailed deer Odocoileus virginianus fawns (n=29) were studied from birth to 1 year of age during 1991-95 on Mount Desert Island (MDI), Maine where deer hunting is prohibited, coyotes Canis latrans have become recently established, and protected U. S. National Park lands are interspersed with private property. Rate of predator-caused mortality was 0.52, with coyote predation (n=8) accounting for at least 47% of mortalities from all causes (n=17). Mortality rate from drowning was 0.24 (n=3), and from vehicles was 0.14 (n=3). Of fawns radio-collared as neonates, 10 of 14 mortalities occurred during the first 2 months of life. Annual rate of fawn survival was 0.26. Survival rate from 6 months to 1 year was 0.65 and 4 mortalities (2 predation, 2 drowning) were observed during this interval. A subgroup of fawns (n = 11) captured near a residential area and along the edge of a coyote territory had a higher (P = 0.002) rate of survival to 1 year of age (S = 0.67) than did fawns from all other areas (n = 18, S = 0.00). Recruitment to 1 year of age was lower than has been observed in other deer populations in the northeastern United States. Low recruitment associated with coyote predation and mortality sources influenced by humans appears to be limiting white-tailed deer populations in this insular landscape.

    Background. Prior studies indicated opioid substitution treatment (OST) reduces mortality risk and improves the odds of accessing highly active antiretroviral therapy (HAART); however, the relative effects of these treatments for human immunodeficiency virus (HIV)–positive people who inject drugs (PWID) are unclear. We determine the independent and joint effects of OST and HAART on mortality, by cause, within a population of HIV-positive PWID initiating HAART. Methods. Using a linked population-level database for British Columbia, Canada, we used time-to-event analytic methods, including competing risks models, proportional hazards models with time-varying covariates, and marginal structural models, to identify the independent and joint effects of OST and HAART on all-cause as well as drug- and HIV-related mortality, controlling for covariates. Results. Among 1727 HIV-positive PWID, 493 (28.5%) died during a median 5.1 years (interquartile range, 2.1–9.1) of follow-up: 18.7% due to drug-related causes, 55.8% due to HIV-related causes, and 25.6% due to other causes. Standardized mortality ratios were 12.2 (95% confidence interval [CI], 9.8, 15.0) during OST and 30.0 (27.1, 33.1) during periods out of OST. Both OST (adjusted hazard, 0.34; 95% CI, .23, .49) and HAART (0.39 [0.31, 0.48]) decreased the hazard of all-cause mortality; however, individuals were at lowest risk of death when these medications were used jointly (0.16 [0.10, 0.26]). Both OST and HAART independently protected against HIV-related death, drug-related death and death due to other causes. Conclusions. While both OST and HAART are life-saving treatments, joint administration is urgently needed to protect against both drug- and HIV-related mortality. PMID:26113656

    Background and Objectives Both hyponatremia and acute kidney injury (AKI) are common and harmful in hospitalized patients. However, their combined effects on patient mortality have been little studied. Methods We retrospectively enrolled 19191 adult patients who were admitted for 1 year. Pre-existing hyponatremia was defined as a serum sodium level < 135 mmol/L on the first measurement of their admission. AKI was defined as a rise in serum creatinine by ≥ 26.5 μmol/L or ≥ 1.5 times of the baseline value of creatinine during the hospital stay. Results The prevalence of pre-existing hyponatremia was 8.2%. During a median 6.0 days of hospital stay, the incidence rates of AKI and in-hospital patient mortality were 5.1% and 0.9%, respectively. Pre-existing hyponatremia independently predicted AKI development and in-hospital mortality (adjusted hazard ratio [HR] 1.300, P = 0.004; HR 2.481, P = 0.002, respectively). Pre-existing hyponatremia and subsequent development of AKI increased in-hospital mortality by 85 times, compared to the patients with normonatremia and no AKI. In subgroup analysis, the AKI group showed higher rates of de novo hypernatremia than the non-AKI group during the admission. De novo hypernatremia, which might be associated with over-correction of hyponatremia, increased in-hospital mortality (HR 3.297, P <0.001), and patients with AKI showed significantly higher rates of de novo hypernatremia than patients without AKI (16.2% vs. 1.4%, P < 0.001, respectively). Conclusion Pre-existing hyponatremia may be associated with the development of AKI in hospitalized patients, and both hyponatremia and hospital-acquired AKI could have a detrimental effect on short term patient mortality, which might be related to the inappropriate correction of hyponatremia in AKI patients.

    STUDY OBJECTIVE--To describe temporal and geographical variations in mortality from acute reactions to opiates or cocaine and the demographic and toxicological characteristics of persons who died from these in major Spanish cities between 1983 and 1991. DESIGN--Descriptive study. Data were obtained retrospectively from pathologists' reports. SETTING--Cities of Madrid, Barcelona, Valencia, Seville, Zaragoza, and Bilbao. SUBJECTS--Deaths from acute reactions to opiates or cocaine were defined as those in which pathologists' reports did not indicate any other cause of death and in which evidence was found of recent consumption of these drugs. MAIN RESULTS--The mortality rate from acute reactions to opiate/cocaine per 100,000 population in the six cities as a whole rose from 1.2 in 1983 to 8.2 in 1991. Average annual rates for the whole period ranged from 1.7 in Seville to 4.9 in Barcelona. The male/female rates ratio was 5.9:1. The mean age of persons who died rose from 25.1 years in 1983 to 28 years in 1991. In more than 90% of the cases in whom toxicological tests were undertaken opiates were detected, and the proportion in which benzodiazepines or cocaine were detected increased during the period studied. CONCLUSIONS--Between 1983 and 1991 mortality from acute reactions to opiates/cocaine rose dramatically in major Spanish cities and significant differences in mortality between cities were found. Deaths were concentrated among men and young people. Acute drug reactions became one of the leading causes of death in persons 15-39 years of age, representing 11.1% of mortality from all causes in 1988 for this age group. Future studies should examine the relationship between the temporal and geographical variations in this type of mortality and various personal, environmental and social factors. PMID:7707007

    Cardiac rehabilitation (CR) produces a host of health benefits related to modifiable cardiovascular risk factors. The purpose of the present investigation was to determine the influence of body weight, assessed through BMI, on acute and long-term improvements in aerobic capacity following completion of CR. Three thousand nine hundred and ninety seven subjects with coronary artery disease (CAD) participated in a 12-week multidisciplinary CR program. Subjects underwent an exercise test to determine peak estimated metabolic equivalents (eMETs) and BMI assessment at baseline, immediately following CR completion and at 1-year follow-up. Normal weight subjects at 1-year follow-up demonstrated the greatest improvement in aerobic fitness and best retention of those gains (gain in peak METs: 0.95 ± 1.1, P < 0.001). Although the improvement was significant (P < 0.001), subjects who were initially classified as obese had the lowest aerobic capacity and poorest retention in CR fitness gains at 1-year follow-up (gain in peak eMETs: 0.69 ± 1.2). Subjects initially classified as overweight by BMI had a peak eMET improvement that was also significantly better (P < 0.05) than obese subjects at 1-year follow-up (gain in peak eMETs: 0.82 ± 1.1). Significant fitness gains, one of the primary beneficial outcomes of CR, can be obtained by all subjects irrespective of BMI classification. However, obese patients have poorer baseline fitness and are more likely to "give back" fitness gains in the long term. Obese CAD patients may therefore benefit from additional interventions to enhance the positive adaptations facilitated by CR.

    The ability of physically restrained and anesthetized wolves to thermoregulate is lessened and could lead to reduced survival, yet no information is available about this subject. Therefore, we analyzed rectal temperatures related to survival 1 year post-capture from 173 adult (non-pup) gray wolves (Canis lupus) captured in modified foot-hold traps for radiocollaring during June–August, 1988–2011, in the Superior National Forest of northeastern Minnesota, USA. The maximum observed rectal temperature (“maxtemp,” ° F, ° C) in each wolf during capture (x = 104.0, 40.0; SD = 2.0, 1.1; min. = 95.9, 35.5; max. = 108, 42.2) was not a significant predictor of survival to 1 year post-capture. Although no weather or morphometric variable was a significant predictor of maxtemps, wolves initially anesthetized with ketamine–xylazine rather than telazol®–xylazine averaged higher maxtemps. This information does not fully address possible effects of high body temperatures related to live-capture and handling of wolves, but it does provide a useful waypoint for future assessments of this relationship and a reassurance to wildlife practitioners that the maxtemps observed in our study did not appear to affect 1-year survival.

Detection of Blastocystis spp. in fecal samples is often performed by clinicians with direct microscopy, which provides low sensitivity, or with culture and polymerase chain reaction testing, a method which is problematic when used with formalin-preserved stool samples. Prior study of Blastocystis and other enteric protists suggests that immunofluorescence antibody (IFA) stain could provide sensitivity and compatibility with formalin, but no information is available on the longevity of Blastocystis sp.'s surface antigens in formalin. We collected fecal samples from animals at a country fair held in the summer of 2009 in Oregon, USA. Samples were tested for the presence of Blastocystis infection using an IFA stain shortly after collection, and again after 1 year, with samples stored refrigerated at 4-8 °C. Most samples collected from steer, pigs, and goats were found to be Blastocystis positive. All fecal samples that were Blastocystis positive initially remained positive after 1 year. Blastocystis-negative samples remained negative. Minimal degradation was observed in stained slides. Blastocystis surface antigens detected by a polyclonal stain remained stable in formalin for a period of at least 1 year.

    This study explored medical conditions associated with mortality among veterans following transfemoral amputation, transtibial amputation, or hip disarticulation. We applied logistic regression models to identify clinical factors associated with mortality postoperatively. The participants included patients with lower-limb amputations (n =2,375) who were discharged from Veterans Health Administration hospitals between October 1, 2002, and September 30, 2003. Most (98.9%) were male. We measured cumulative in-hospital, 3-month, and 1-year-mortality. The results were 180 in-hospital deaths, 368 by 3 months, and 634 by the 1-year postsurgical amputation date. Those who had perioperative systemic sepsis (odds ratio = 4.28, 95% confidence interval= 2.87–6.39) had more than a fourfold increased likelihood of in -hospital mortality. Congestive heart failure, renal failure, and liver disease were significantly associated with mortality at all time periods. Metastatic cancer was associated only at 3 months and 1 year. We concluded that high medical complexity and mortality rates attest to the need for careful medical oversight during the postacute rehabilitation period. PMID:17436177

    OBJECTIVE: The improvement of obstetric services is one of the key components of the Safe Motherhood Programme. Reviewing maternal deaths and complications is one method that may make pregnancy safer, but there is no evidence about the effectiveness of this strategy. The objective of our before and after study is to assess the effect of facility-based maternal deaths reviews (MDR) on maternal mortality rates in a district hospital in Senegal that provides primary and referral maternity services. METHODS: We included all women who were admitted to the maternity unit for childbirth, or within 24 hours of delivery. We recorded maternal mortality during a 1-year baseline period from January to December 1997, and during a 3-year period from January 1998 to December 2000 after MDR had been implemented. Effects of MDR on organization of care were qualitatively evaluated. FINDINGS: The MDR strategy led to changes in organizational structure that improved life-saving interventions with a relatively large financial contribution from the community. Overall mortality significantly decreased from 0.83 (95% CI (confidence interval) = 0.60 -1.06) in baseline period to 0.41 (95% CI = 0.25 -0.56) per 100 women 3 years later. CONCLUSION: MDR had a marked effect on resources, management and maternal outcomes in this facility. However, given the design of our study and the local specific context, further research is needed to confirm the feasibility of MDR in other settings and to confirm the benefits of this approach for maternal health in developing countries.

    Objective HIV-infected patients are at increased risk for cardiovascular disease, which may be mediated in part by inflammation. Surrogate marker studies suggest an increased prevalence of vascular abnormalities in HIV infection. We examined the association of all-cause mortality in HIV-infected patients with carotid artery intima-media thickness (cIMT) and high-sensitivity C-reactive protein (hsCRP). Design and Methods Baseline risk factors, cIMT and hsCRP were prospectively measured in 327 HIV-infected participants. Follow-up time with median of 3.1 years was calculated from baseline to death or censored dated 7/31/07. Cox Proportional Hazards models were used to study risk factors associated with mortality. Results Thirty eight (11.6 %) of participants have died since study enrollment. CIMT was significantly higher in those who died and decedents were significantly more likely to have cIMT above the 75th percentile. Those who died had higher hsCRP than those alive and more had hsCRP values above 3 mg/L. CD4 count was lower and log10 viral load was higher in decedents, but antiretroviral regimens were similar in both groups. CIMT and hsCRP levels were significantly associated with mortality (HR=2.74, 95% CI 1.26 to 5.97, p=0.01; HR=2.38, 95% CI 1.15 to 4.9, p=0.02). Conclusions Our study demonstrated a strong association of carotid IMT and hsCRP with all-cause death in this HIV-infected population despite being similar with respect to exposure to antiretroviral medications. Together these surrogate markers may be indices of chronic inflammation and unfavorable outcomes in HIV-positive patients. PMID:21130995

    Background Whether CKD recognition in an electronic health record (EHR) problem list improves processes of care or clinical outcomes of ESRD and death is unclear. Methods We identified patients who had at least 1 year of follow up (2005–2009) in our EHR based CKD registry (n=25,742). CKD recognition was defined by having ICD-9 codes for CKD, diabetic kidney disease, or hypertensive kidney disease in the problem list. We calculated proportions of patients with and without CKD recognition and examined differences by demographics, clinical factors, and development of ESRD or mortality. We evaluated differences in the proportion of patients with CKD specific labs checked before and after recognition among cases and propensity-matched controls. Results Only 11% (n=2735) had CKD recognition in the problem list and they were younger (68 vs. 71 yrs), a higher proportion were male (61% vs. 37%) and African-American (21% vs. 10%) compared to those unrecognized. CKD-specific labs for patients with eGFR 30–59 including iPTH (23% vs. 6%), Vitamin D (22% vs. 18%), phosphorus (29% vs. 7%), and a urine check for proteinuria (55% vs. 36%) were significantly more likely to be done among those with CKD recognition. (all p<0.05) Similar results were found for eGFR<30 except for proteinuria and in our propensity score matched control analysis. There was no independent association of CKD recognition with ESRD or mortality. Conclusions CKD recognition in the EHR problem list was low, but translated into more CKD specific processes of care; however ESRD or mortality were not affected. PMID:24714513

    OBJECTIVE In the United States, young and middle-aged black men have significantly higher total mortality than any other racial or ethnic group. We describe the characteristics of US counties with low non–Hispanic Black or African American male mortality (ages 25-64 years, 1999-2007). METHODS Information was accessed through public data, the US Census, the US Compressed Mortality File, and the Native American Graves Repatriation Act military database. RESULTS Of 1307 counties with black mortality rates classified as reliable by the National Center for Health Statistics (at least 20 deaths), 66 recorded lower mortality among black men than corresponding US whites. Most notable, 97% of the 66 counties were home to or adjacent a military installation versus 37% of comparable US counties (P .001). Blacks in these counties had less poverty, higher percentages of elderly civilian veterans, and higher per capita income. Within these counties, national black:white disparities in mortality were eliminated for ischemic heart disease, accidents, diseases of the liver, chronic lower respiratory diseases, and mental disorder from psychoactive substance use. Application of age-, race-, ethnicity-, gender-, and urbanization-specific mortality rates from counties with relatively low mortality would reduce the black:white mortality rate ratio for black men aged 25 to 64 years from 1.67 to 1.20 nationally and to 1.00 in areas outside large central metropolitan areas. CONCLUSIONS These descriptive data demonstrate a small number of communities with low mortality rates among young and middle-aged black/African American men. Their characteristics may provide clinical and public health insights to reduce these higher mortality rates in the US population. Analytic epidemiologic studies are necessary to test these hypotheses. PMID:23260504

    Background Data from the Chinese police service suggest substantial reductions in road traffic injuries since 2002, but critics have questioned the accuracy of those data, especially considering conflicting data reported by the health department. Methods To address the gap between police and health department data and to determine which may be more accurate, we conducted a simulation study based on the modified Smeed equation, which delineates a non-linear relation between road traffic mortality and the level of motorization in a country or region. Our goal was to simulate trends in road traffic mortality in China and compare performances in road traffic safety management between China and 13 other countries. Results Chinese police data indicate a peak in road traffic mortalities in 2002 and a significant and a gradual decrease in population-based road traffic mortality since 2002. Health department data show the road traffic mortality peaked in 2012. In addition, police data suggest China’s road traffic mortality peaked at a much lower motorization level (0.061 motor vehicles per person) in 2002, followed by a reduction in mortality to a level comparable to that of developed countries. Simulation results based on health department data suggest high road traffic mortality, with a mortality peak in 2012 at a moderate motorization level (0.174 motor vehicles per person). Comparisons to the other 13 countries suggest the health data from China may be more valid than the police data. Conclusion Our simulation data indicate China is still at a stage of high road traffic mortality, as suggested by health data, rather than a stage of low road traffic mortality, as suggested by police data. More efforts are needed to integrate safety into road design, improve road traffic management, improve data quality, and alter unsafe behaviors of pedestrians, drivers and passengers in China.

    Objective To examine whether high milk consumption is associated with mortality and fractures in women and men. Design Cohort studies. Setting Three counties in central Sweden. Participants Two large Swedish cohorts, one with 61 433 women (39-74 years at baseline 1987-90) and one with 45 339 men (45-79 years at baseline 1997), were administered food frequency questionnaires. The women responded to a second food frequency questionnaire in 1997. Main outcome measure Multivariable survival models were applied to determine the association between milk consumption and time to mortality or fracture. Results During a mean follow-up of 20.1 years, 15 541 women died and 17 252 had a fracture, of whom 4259 had a hip fracture. In the male cohort with a mean follow-up of 11.2 years, 10 112 men died and 5066 had a fracture, with 1166 hip fracture cases. In women the adjusted mortality hazard ratio for three or more glasses of milk a day compared with less than one glass a day was 1.93 (95% confidence interval 1.80 to 2.06). For every glass of milk, the adjusted hazard ratio of all cause mortality was 1.15 (1.13 to 1.17) in women and 1.03 (1.01 to 1.04) in men. For every glass of milk in women no reduction was observed in fracture risk with higher milk consumption for any fracture (1.02, 1.00 to 1.04) or for hip fracture (1.09, 1.05 to 1.13). The corresponding adjusted hazard ratios in men were 1.01 (0.99 to 1.03) and 1.03 (0.99 to 1.07). In subsamples of two additional cohorts, one in males and one in females, a positive association was seen between milk intake and both urine 8-iso-PGF2α (a biomarker of oxidative stress) and serum interleukin 6 (a main inflammatory biomarker). Conclusions High milk intake was associated with higher mortality in one cohort of women and in another cohort of men, and with higher fracture incidence in women. Given the observational study designs with the inherent possibility of residual confounding and reverse causation phenomena, a

    Objective Geographic patterns in total mortality and in mortality by cause of death are widely known to exist in many countries. However, the geographic pattern of inequalities in mortality within these countries is unknown. This study shows mathematically and graphically the geographic pattern of mortality inequalities by education in Spain. Methods Data are from a nation-wide prospective study covering all persons living in Spain's 50 provinces in 2001. Individuals were classified in a cohort of subjects with low education and in another cohort of subjects with high education. Age- and sex-adjusted mortality rate from all causes and from leading causes of death in each cohort and mortality rate ratios in the low versus high education cohort were estimated by geographic coordinates and province. Results Latitude but not longitude was related to mortality. In subjects with low education, latitude had a U-shaped relation to mortality. In those with high education, mortality from all causes, and from cardiovascular, respiratory and digestive diseases decreased with increasing latitude, whereas cancer mortality increased. The mortality-rate ratio for all-cause death was 1.27 in the southern latitudes, 1.14 in the intermediate latitudes, and 1.20 in the northern latitudes. The mortality rate ratios for the leading causes of death were also higher in the lower and upper latitudes than in the intermediate latitudes. The geographic pattern of the mortality rate ratios is similar to that of the mortality rate in the low-education cohort: the highest magnitude is observed in the southern provinces, intermediate magnitudes in the provinces of the north and those of the Mediterranean east coast, and the lowest magnitude in the central provinces and those in the south of the Western Pyrenees. Conclusion Mortality inequalities by education in Spain are higher in the south and north of the country and lower in the large region making up the central plateau. This geographic

    With the objective of testing whether or not mortality decline is independent of economic development, changes are analyzed in mortality levels and consumption patterns in post-World War 2 Taiwan. According to the official statistics, the crude death rate in post-war Taiwan declined continuously from 11.5/1000 in 1950 to 6.8 in 1960, and then to 4.8 in 1974. During the same period, Taiwan also experienced impressive economic growth, with real per capita income rising from less than $150 in the early 1950s to almost $200 in the early 1960s, and then to more than $400 since 1973. Hence, it is hypothesized that mortality decline in post-war Taiwan was not independent of its economic development. The data for the study are annual aggregate statistics from official reports from 1950 to 1974. After eliminating the effect of the age composition from the mortality trend, the data show that the level of mortality improved much more during the 1st 1/2 of the study than during the last 1/2. Attempts were made to clarify the relationship between economic development and mortality decline by analyzing changes of mortality levels and consumption patterns. Although some weaknesses appear in the study, the preliminary results seem to imply that the mortality reduction in post-war Taiwan was not independent of economic progress. If more information becomes available, further investigation concerning this issue should lead to more conclusive results.

    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

    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.

    Background Dialysis patients have high cardiovascular mortality risk. This study aimed to investigate the association between SNPs of genes involved in vascular processes and mortality in dialysis patients. Methods Forty two SNPs in 25 genes involved in endothelial function, vascular remodeling, cell proliferation, inflammation, coagulation and calcium/phosphate metabolism were genotyped in 1330 incident dialysis patients. The effect of SNPs on 5-years cardiovascular and non-cardiovascular mortality was investigated. Results The mortality rate was 114/1000 person-years and 49.4% of total mortality was cardiovascular. After correction for multiple testing, VEGF rs699947 was associated with all-cause mortality (HR1.48, 95% CI 1.14–1.92). The other SNPs were not associated with mortality. Conclusions This study provides further evidence that a SNP in the VEGF gene may contribute to the comorbid conditions of dialysis patients. Future studies should unravel the underlying mechanisms responsible for the increase in mortality in these patients. PMID:26587841

    Background 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). Methods 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. Results 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. Conclusion Thyroid cancer mortality increased until 2000 in Korea. It started to decrease from 2000. PMID:25559576

    Study objective: Heat and cold have been associated with increased mortality, independently of seasonal trends, but details are little known. This study explores associations between mortality and temperature in two European capitals—Sofia and London—using four years of daily deaths, air pollution, and weather data. Design: Generalised additive models were used to permit non-linear modelling of confounders such as season and humidity, and to show the shape of mortality-temperature relations—using both two day and two week average temperatures separately. Models with linear terms for heat and cold were used to estimate lags of effect, linear effects, and attributable fractions. Participants: 44 701 all age all cause deaths in Sofia (1996–1999) and 256 464 in London (1993–1996). Main results: In London, for each degree of extreme cold (below the 10th centile of the two week mean temperature), mortality increased by 4.2% (95% CI 3.4 to 5.1), and in Sofia by 1.8% (0.6 to 3.9). For each degree rise above the 95th centile of the two day mean, mortality increased by 1.9% (1.4 to 2.4) in London, and 3.5% (2.2 to 4.8) in Sofia. Cold effects appeared after lags of around three days and lasted—particularly in London—at least two weeks. Main heat effects occurred more promptly. There were inverse associations at later lags for heat and cold in Sofia. Conclusions: Average temperatures over short periods do not adequately model cold, and may be inadequate for heat if they ignore harvesting effects. Cold temperatures in London, particularly, seem to harm the general population and the effects are not concentrated among persons close to death. PMID:12883072

    Background The Love Canal is a rectangular 16-acre, 10-ft deep chemical waste landfill situated in a residential neighborhood in Niagara Falls, New York. This seriously contaminated site first came to public attention in 1978. No studies have examined mortality in the former residents of the Love Canal neighborhood (LC). Objective The aim of this study was to describe the mortality experience of the former LC residents from the years 1979–1996. Methods From 1978 to 1982, 6,181 former LC residents were interviewed. In 1996, 725 deaths from 1979–1996 were identified in this cohort, using state and national registries. We compared mortality rates with those of New York State (NYS) and Niagara County. Survival analysis examined risks by potential exposure to the landfill. Results We were unable to demonstrate differences in all-cause mortality for either comparison population for 1979 1996. Relative to NYS, the standardized mortality ratio (SMR) was elevated [SMR = 1.39; 95% confidence interval (CI), 1.16–1.66] for death from acute myocardial infarction (AMI), but not relative to Niagara County. Death from external causes of injury was also elevated relative to both NYS and Niagara County, especially among women (SMR = 1.95; 95% CI, 1.25 2.90). Conclusions The role of exposure to the landfill in explaining these excess risks is not clear given limitations such as multiple comparisons, a qualitative exposure assessment, an incomplete cohort, and no data on deaths prior to 1978. Lack of elevation for AMI when compared with Niagara County but not NYS suggests possible regional differences. However, direct cardiotoxic or neurotoxic effects from landfill chemicals or indirect effects mediated by psychological stress cannot be ruled out. Revisiting the cohort in the future could reveal patterns that are not yet apparent. PMID:19270790

    OBJECTIVE--To explore associations between exposure to cement dust and cause specific mortality and tumour morbidity, especially gastrointestinal tumours. DESIGN--A retrospective cohort study. SUBJECTS AND SETTING--2400 men, employed for at least 12 months in two Swedish cement factories. MAIN OUTCOME MEASURES--Cause specific morality from death certificates (1952-86). Cancer morbidity from tumour registry information (1958-86). Standardised mortality rates (SMRs; national reference rates) and standardised morbidity incidence rates (SIRs; regional reference rates) were calculated. RESULTS--An increased risk of colorectal cancer was found > or = 15 years since the start of employment (SIR 1.6, 95% confidence interval (95% CI) 1.1-2.3), mainly due to an increased risk for tumours in the right part of the colon (SIR 2.7, 95% CI 1.4-4.8), but not in the left part (SIR 1.0, 95% CI 0.3-2.5). There was a numerical increase of rectal cancer (SIR 1.5, 95% CI 0.8-2.5). Exposure (duration of blue collar employment)-response relations were found for right sided colon cancer. After > or = 25 years of cement work, the risk was fourfold (SIR 4.3, 95% CI 1.7-8.9). There was no excess of stomach cancer or respiratory cancer. Neither total mortality nor cause specific mortality were significantly increased. CONCLUSIONS--Diverging risk patterns for tumours with different localisations within the large bowel were found in the morbidity study. Long term exposure to cement dust was a risk factor for right sided colon cancer. The mortality study did not show this risk. PMID:8457494

    Previous 1-year mortality studies of pelvic fractures in elderly patients have focused on pubic rami fractures, in elderly patients with multiple injuries, or both. Baseline information on the 1-year mortality of isolated pelvic fractures in elderly patients is unavailable. The purpose of this study was to evaluate the 1-year mortality of elderly patients (aged 60 years or older) after isolated pelvic fractures with posterior ring involvement (Orthopaedic Trauma Association type 61-B and C). All patients aged 60 years or older treated for pelvic injuries at a single Level I trauma center over a 12-year period were retrospectively reviewed (N=1223). Exclusion criteria were associated injuries to other body systems (Abbreviated Injury Scale greater than 2), ballistic injuries, long bone fractures, concurrent acetabular fractures, and type 61-A fractures or isolated pubic rami fractures without posterior involvement. Mortality data were obtained from the Social Security Death Index. Seventy patients met the inclusion criteria. Patients treated nonoperatively were significantly older compared with those treated operatively. However, the Charlson Comorbidity Index did not significantly differ between treatment groups. A significantly higher percentage of type-B fractures (83.0%) were treated nonoperatively compared with type-C fractures, which were treated operatively 88.2% of the time. Mortality rates at 3 and 6 months and 1 year postoperatively were 7.1%, 11.4%, and 12.9%, respectively. These results suggest that the 1-year mortality rates of isolated pelvic fractures in elderly patients are lower than those reported previously for hip fractures and pelvic fractures with concurrent injuries. Although age was identified as a significant variable differing between patients treated operatively vs nonoperatively, comorbidities were not. PMID:23746012

    Hip fractures are associated with high excess mortality. Education is an important determinant of health, but little is known about educational inequalities in post-hip fracture mortality. Our objective was to investigate educational inequalities in post-hip fracture mortality and to examine whether comorbidity or family composition could explain any association. We conducted a register-based population study of Norwegians aged 50 years and older from 2002 to 2010. We measured total mortality according to educational attainment in 56,269 hip fracture patients (NORHip) and in the general Norwegian population. Both absolute and relative educational inequalities in mortality in people with and without hip fracture were compared. There was an educational gradient in post-hip fracture mortality in both sexes. Compared with those with primary education only, the age-adjusted relative risk (RR) of mortality in hip fracture patients with tertiary education was 0.82 (95% confidence interval [CI] 0.77-0.87) in men and 0.79 (95% CI 0.75-0.84) in women. Additional adjustments for Charlson comorbidity index, marital status, and number of children did not materially change the estimates. Regardless of educational attainment, the 1-year age-adjusted mortality was three- to fivefold higher in hip fracture patients compared with peers in the general population without fracture. The absolute differences in 1-year mortality according to educational attainment were considerably larger in hip fracture patients than in the population without hip fracture. Absolute educational inequalities in mortality were higher after hip fracture compared with the general population without hip fracture and were not mediated by comorbidity or family composition. Investigation of other possible mediating factors might help to identify new targets for interventions, based on lower educational attainment, to reduce post-hip fracture mortality.

    Background: Apical periodontitis (AP) is one of the most prevalent diseases of the teeth. Treatment of AP is based on the removal of the cause, i.e., bacteria from the root canals. Achievement of adequate bacterial eradication in one appointment treatment remains a controversy. Aim: This prospective study was conducted with the objective to compare the periapical healing of teeth with AP treated in (a) single visit versus (b) two visits, either with or without Vitapex as an intracanal medicament. Subjects and Methods: Patients were selected randomly from the Department of Conservative Dentistry and Endodontics. Forty-three patients (81 teeth) met the inclusion criteria, i.e., AP (both symptomatic and asymptomatic) visible radiographically size ≥2 mm × 2 mm, not suffering from any immune-compromising disease, age between 16 and 65 years and tooth not accessed previously. Patients were randomly divided into three groups, i.e., single-visit group (Group 1), multi-visit group without any intracanal medicament (Group 2), and multi-visit group with Vitapex as interim intracanal medicament (Group 3). Comparison was done radiographically using periapical index (PAI). The primary outcome measure was the change in periapical radiolucency after 1 year assessed by PAI scores. The Mann-Whitney U-test was used to evaluate differences between groups at baseline (immediate postoperative) and at the 12-month follow-up evaluation. Change in PAI score for each group from baseline to 12-month follow-up evaluation was tested with the Wilcoxon signed rank test. The secondary outcome measures, proportion of teeth in each group that could be considered improved (decreased PAI score) or healed (PAI <2), were assessed with the Chi-square test. Results: No statistically significant difference in periapical healing was found between three groups. Conclusion: After 1-year evaluation, no difference in periapical healing was found between single-visit treatment and multi-visit treatment

    Background A farming environment confers strong protection against allergy development. We have previously shown that farming mothers consume more full-fat dairy than control mothers, who instead consume more low-fat dairy, margarine, and oils; margarine and oil intake was associated with increased risk of allergy development in their children. Objectives The aims of this study were to investigate the differences in diet between children in farming and control families at 1 year of age, to investigate the relation between the diets of the mothers and their children, and to relate the children's diet to allergy development. Design The diet of 1-year-old children from dairy farming families (n=28) and from control families in the same rural area (n=37) was assessed by 24-h dietary recalls, followed by 24-h food diaries. Allergy was diagnosed by pediatricians at 3 years of age using strict predefined criteria. Results Farm children had a higher intake of farm milk, whole cream, cholesterol, saturated fat, and fat in total and tended to eat more butter, while controls consumed more carbohydrates and poultry and tended to eat more margarine. Farm children also had higher intakes of homemade porridge/gruel, oily fish, and iodine. The intake of butter and whole milk in children and mothers correlated significantly in farm families but not in controls. A weak negative association was found between seafood intake and allergy development, while allergy was positively associated with the intake of pork as well as zinc in the control group; these intakes also correlated with each other. Conclusions Consistent with mothers in farming families, the children consumed more full-fat dairy and saturated fat than did controls, but this could not be linked to the low risk of allergy in the farming group. Seafood intake might protect against allergy development, in accordance with earlier findings. PMID:27534847

    Changes in purine derivatives may be considered as signs of training-induced metabolic adaptations. The purpose of this study was to assess the effect of a 1-year training cycle on the response of hypoxanthine (Hx) concentration and Hx-guanine phosphoribosyltransferase (HGPRT) activity. Three groups of middle-aged male runners were examined: 11 elite master runners (EL; 46.0 ± 3.8 years), 9 amateur runners (AM; 45.1 ± 4.7 years), and 10 recreational runners (RE; 45.9 ± 6.1 years). Plasma Hx concentration and erythrocyte HGPRT activity were measured in three characteristic training phases of the annual cycle. Significant differences in post-exercise Hx concentration and resting HGPRT activity were demonstrated between the EL, AM, and RE groups across consecutive training phases. The EL group showed lowest Hx concentration and highest HGPRT activity compared to the AM and RE groups. Analogous differences were observed between the AM and RE groups during specific preparation. For the EL group, the changes were observed across all examinations and the lowest Hx concentration and highest HGPRT activity were found in the competition phase. Significant change was also revealed in the AM group between the general and specific preparation, but not in the competition phase. No significant changes were found in the RE runners who did not use anaerobic exercise in their training. In conclusion, a long-lasting endurance training, incorporating high-intensity exercise, results in significant changes in purine metabolism, whereas training characterized by constant low-intensity exercise does not. Plasma Hx concentration and erythrocyte HGPRT activity may be sensitive indicators of training adaptation and training status in middle-aged athletes.

    Background: This study was designed to compare the efficacy of the medical treatment versus the surgical treatment approach to decompression of trigger point nerves in patients with migraine headaches. Materials and Methods: Fifty volunteers were randomly assigned to the medical treatment group (n = 25) or the surgical treatment group (n = 25) after examination by the team neurologist to ensure a diagnosis of migraine headache. All patients received botulinum toxin type A to confirm the trigger sites. The surgical treatment group underwent surgical deactivation of the trigger site(s). The medical treatment group underwent prophylactic pharmacologic interventions by the neurologist. Pretreatment and 12-month posttreatment migraine headache frequency, duration, and intensity were analyzed and compared to determine the success of the treatments. Results: Nineteen of the 25 patients (76%) in the surgical treatment group and 10 of the 25 patients (40%) in the medical treatment group experienced a successful outcome (at least a 50% decrease in migraine frequency, duration, or intensity) after 1 year from surgery. Surgical treatment had a significantly higher success rate than medical treatment (P < 0.001). Nine patients (36%) in the surgical treatment group and one patient (4%) in the medical treatment group experienced cessation of migraine headaches. The elimination rate was significantly higher in the surgical treatment group than in the medical treatment group (P < 0.001). Conclusions: Based on the 1-year follow-up data, there is strong evidence that surgical manipulation of one or more migraine trigger sites can successfully eliminate or reduce the frequency, duration, and intensity of migraine headaches in a lasting manner.

    Purpose The purpose of this study was to report on the axial length, refraction, and retinal vascularization 1 year after ranibizumab or bevacizumab treatment for threshold retinopathy of prematurity. Methods The authors conducted a comparative, consecutive, original study. Results Twenty-five eyes of 13 patients with threshold retinopathy of prematurity received one intravitreal ranibizumab treatment, and 15 eyes of eight patients received one intravitreal bevacizumab treatment. In the ranibizumab group, the mean gestational age was 26.15±2.08 weeks, with a mean birth weight of 811.15±287.3 g. In the bevacizumab group, the mean gestational age was 26.50±2.14 weeks, with a mean birth weight of 938.38±200.4 g. The mean axial length was 20.34±0.97 mm and the mean spherical equivalent was 0.46±1.36 D in the ranibizumab group, with complete vascularization in 15 of 25 (60%) eyes. The mean axial length was 20.91±1.54 mm and the mean spherical equivalent was −0.60±3.86 D in the bevacizumab group, with complete vascularization in seven of 15 (46.7%) eyes. Conclusion There were no significant differences in the axial length and refraction between children with threshold retinopathy of prematurity who received intravitreal bevacizumab compared to those who received ranibizumab after 1 year of follow-up. It appeared that the ranibizumab treatment could achieve more complete retinal vascularization than the bevacizumab treatment; however, there was no statistical significance and long-term follow-up is needed.

  11. Mortality rates decline in Malaysia.

    PubMed

    1991-11-01

    Experiencing remarkable decreases in mortality rates over the past 3 decades, Malaysia currently has one of the lowest mortality rates among developing countries, a rate that compares favorably with those of developed countries. Between 1957 and 1989, the crude death rate dropped from 12.4/1000 population to 4.6. Over the same period, Malaysia recorded even greater decreases in the infant mortality rate, from 75.5/1000 births to 15.2. The Maternal mortality rate also declined from 1.48 in 1970 to 0.24 in 1988. The data indicates that mortality rates vary from state to state, and that rural areas have a higher mortality than urban areas. According to a study by the National Population and Family Development Board, the use of maternal and child health services has played an important role in reducing neonatal, perinatal, infant, child, and maternal mortality rates. Nearly all women in Malaysia receive antenatal services. While the country has achieved great gains on mortality rates, programs focusing on specific age and socioeconomic groups could lead to even greater reductions. The Minister for National Unity and Social Development, Dato Napsiah Omar, has called for the development of programs designed to improve the population's quality of life.

    Traditional burn mortality models are derived using all age groups. We hypothesized that age variably impacts mortality after burn and that age-specific models for children, adults, and seniors will more accurately predict mortality than an all-ages model. We audited data from the American Burn Association (ABA) National Burn Repository (NBR) from 2000 to 2009 and used mixed effect logistic regression models to assess the influence of age, total body surface area (TBSA) burn, and inhalation injury on mortality. Mortality models were constructed for all ages and age-specific models: children (<18 years), adults (18-60 years), and seniors (>60 years). Model performance was assessed by area under the receiver operating curve (AUC). Main effect and two-way interactions were used to construct age-group specific mortality models. Each age-specific model was compared to the All Ages model. Of 286,293 records 100,051 had complete data. Overall mortality was 4% but varied by age (17% seniors, <1% children). Age, TBSA, and inhalation injury were significant mortality predictors for all models (p<0.05). Differences in predicted mortality between the All Ages model and the age-specific models occurred in children and seniors. In the age-specific pediatric model, predicted mortality decreased with age; inhalation injury had greater effect on mortality than in the All Ages model. In the senior model mortality increased with age. Seniors had greater increase in mortality per 1% increment in burn size and 1 year increase in age than other ages. The predicted mortality in seniors using the senior-specific model was higher than in the All Ages model. "One size fits all" models for predicting burn outcomes do not accurately reflect the outcomes for seniors and children. Age-specific models for children and seniors may be advisable. PMID:24846014

    Background 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. Methods 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. Results 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. Conclusion 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

    Background Amiodarone is a frequently used antiarrhythmic drug in patients with end-stage heart failure. Given its long half-life, pre-transplant use of amiodarone has been controversially discussed, with divergent results regarding morbidity and mortality after heart transplantation (HTX). Aim The aim of this study was to investigate the effects of long-term use of amiodarone before HTX on early post-transplant atrial fibrillation (AF) and mortality after HTX. Methods Five hundred and thirty patients (age ≥18 years) receiving HTX between June 1989 and December 2012 were included in this retrospective single-center study. Patients with long-term use of amiodarone before HTX (≥1 year) were compared to those without long-term use (none or <1 year of amiodarone). Primary outcomes were early post-transplant AF and mortality after HTX. The Kaplan–Meier estimator using log-rank tests was applied for freedom from early post-transplant AF and survival. Results Of the 530 patients, 74 (14.0%) received long-term amiodarone therapy, with a mean duration of 32.3±26.3 months. Mean daily dose was 223.0±75.0 mg. Indications included AF, Wolff–Parkinson–White syndrome, ventricular tachycardia, and ventricular fibrillation. Patients with long-term use of amiodarone before HTX had significantly lower rates of early post-transplant AF (P=0.0105). Further, Kaplan–Meier analysis of freedom from early post-transplant AF showed significantly lower rates of AF in this group (P=0.0123). There was no statistically significant difference between patients with and without long-term use of amiodarone prior to HTX in 1-year (P=0.8596), 2-year (P=0.8620), 5-year (P=0.2737), or overall follow-up mortality after HTX (P=0.1049). Moreover, Kaplan–Meier survival analysis showed no statistically significant difference in overall survival (P=0.1786). Conclusion Long-term use of amiodarone in patients before HTX significantly reduces early post-transplant AF and is not associated with

    The medical records of all children less than 1 year of age presenting to the Accident and Emergency Department over a 5-year period (1995-1999) with a fracture were retrospectively reviewed for possible abuse. Seventy-four children presented with fractures during the study period, with a mean age at presentation of 5 months (range 2 weeks to 1 year). Of these children, 46 had skull fractures and 28 had long bone fractures. Children were classified into one of seven categories: definite abuse, likely abuse, suspicious, likely accident, definite accident, neglect, or unknown cause. A three-tier system of grading for possible abuse was then used to analyze variance. The first tier consisted of the initial assessment by staff clinicians, the second retrospectively by an orthopaedic registrar, and the third retrospectively by a designated doctor in child protection (consultant pediatrician), all using the same information from the case notes. The use of the three-tier system of grading demonstrated a variance in the diagnosis of nonaccidental injury. The possibility of abuse was underestimated at the time of the original injury in over a quarter of cases (28.4%) when compared with the assessment by the consultant pediatrician. In 34 children (46%), there was no written documentation that nonaccidental injury was ever considered. While management depends on local guidelines and arrangements, the authors would advise that all children under 1 year of age with a fracture should be admitted to the hospital and referred to a pediatrician for child protection assessment.

    OBJECTIVE: The aim of this study was to evaluate the roles of the Taql and Bsml vitamin D receptor gene polymorphisms in hospital mortality of burn patients. METHODS: In total, 105 consecutive burn injury patients over 18 years in age who were admitted to the Burn Unit of Bauru State Hospital from January to December 2013 were prospectively evaluated. Upon admission, patient demographic information was recorded and a blood sample was taken for biochemical analysis to identify the presence of the Taql(rs731236) and Bsml(rs1544410) polymorphisms. All of the patients were followed over their hospital stay and mortality was recorded. RESULTS: Eighteen of the patients did not sign the informed consent form, and there were technical problems with genotype analysis for 7 of the patients. Thus, 80 patients (mean age, 42.5±16.1 years) were included in the final analysis. In total, 60% of the patients were male, and 16.3% died during the hospital stay. The genotype frequencies for the Taql polymorphism were 51.25% TT, 41.25% TC and 7.50% CC; for the Bsml polymorphism, they were 51.25% GG, 42.50% GA and 6.25% AA. In logistic regression analysis, after adjustments for age, gender and total body surface burn area, there were no associations between the Taql (OR: 1.575; CI95%: 0.148-16.745; p=0.706) or Bsml (OR: 1.309; CI95%: 0.128-13.430; p=0.821) polymorphisms and mortality for the burn patients. CONCLUSIONS: Our results suggest that the Taql and Bsml vitamin D receptor gene polymorphisms are not associated with hospital mortality of burn patients. PMID:27626478

    Background Clopidogrel is recommended after acute myocardial infarction (AMI) but has variable efficacy and safety, in part related to the effect of cytochrome P450 (CYP) polymorphisms on its metabolism. The effect of CYP polymorphisms on cardiovascular events among clopidogrel-treated patients after AMI remains controversial, and no studies to date have investigated the association of CYP variants with outcomes in African American patients. Methods and Results 2732 subjects (2062 Caucasians; 670 African Americans) hospitalized with AMI enrolled in the prospective, multicenter TRIUMPH study were genotyped for CYP polymorphisms. The majority of Caucasians (79%) and African Americans (64.4%) were discharged on clopidogrel. Among Caucasians, carriers of the loss-of-function CYP2C19*2 allele had significantly increased 1-year mortality (adjusted HR: 1.70; CI: 1.01 to 2.86; p=0.046), and a trend toward increased rate of recurrent MI (adjusted HR: 2.10; CI 0.95 to 4.63; p= 0.066). Among African Americans, increased 1-year mortality was associated with the gain of function CYP2C19*17 allele (adjusted HR for *1/*17 vs. *1/*1: 2.02; CI: 0.92 to 4.44; *17/*17 vs. *1/*1: 8.97; CI: 3.34 to 24.10; p< 0.0001) and the CYP1A2*1C allele (adjusted HR for *1/*1C vs. *1/*1: 1.89; CI: 0.85 to 4.22; *1C/*1C vs. *1/*1: 4.96; CI: 1.69 to 14.56; p= 0.014). Bleeding events were significantly more common among African American carriers of CYP2C19*17 or CYP1A2*1C. Conclusions Both loss of function and gain of function CYP polymorphisms affecting clopidogrel metabolism are associated with increased mortality among clopidogrel treated patients following AMI; the specific polymorphism and the putative mechanism vary according to race.

    The Auburn University Master of Science program in Applied Behavior Analysis was designed to accommodate not only the requirements of the Behavior Analyst Certification Board for approved course sequences and practicum training, but unavoidable limitations in faculty and other resources. These limitations were incompatible with the more traditional 2-year curriculum model, so a 1-year program was designed that met the necessary conditions. This article describes the resulting academic and practicum curriculum, the key funding mechanisms that allowed the program to develop, and the opportunities and benefits that this model afforded.

    There are regional differences in the survival of incident dialysis patients, but few studies have investigated the reasons. We assessed the effect of institutional factors on factors on survival (by both cross-sectional assessment and after a 1-year investigation) in a cohort of the Japanese Society for Dialysis Therapy (JSDT). We investigated 20 institutional factors from 3958 dialysis institution data of the 47 prefectures in Japan in 2005 and the JSDT database of 102,011 patients who commenced dialysis during 2004-2006. Univariate regression analysis between 20 factors and 1-year survival rate, Kaplan-Meier method, log-rank test, and Cox's proportional hazard model between the upper 24 and the lower 23 prefectures of the significant factors were carried out. The age-adjusted 1-year survival rate was 0.832 ± 0.027. Deaths occurred in 15.0% in 24 upper survival prefectures and 18.7% in 23 lower survival prefectures (P < 0.0001, unadjusted hazard ratio [HR] of death in lower survival prefectures: 1.26, 95% confidence interval [CI]: 1.17-1.40). A total of five factors among males were significantly correlated with 1-year survival according to the univariate regression analysis. Among them, three factors (night-time center/total dialysis center ratio [males: P < 0.0001, age, genders, and presence of diabetes adjusted HR: 0.88, 95% CI: 0.81-0.93], number of full-time dialysis nurses [males: P = 0.0427, 0.94, 0.87-1.00], number of full-time dialysis dietitians [males: P = 0.0084, 0.92, 0.85-0.98], respectively) were significant in Kaplan-Meier analysis, log-rank test, and the Cox's model. Institutional factors were closely related to the survival of incident dialysis patients, and regional differences in the survival may be explained, at least partly, by these factors.

    Traumatic spinal epidural hematoma is uncommon in children, making rapid diagnosis difficult. In this report, we present a case of traumatic cervical epidural hematoma in a 1-year-old boy, diagnosed with computed tomography scanning and magnetic resonance imaging (MRI). Management was conservative and the lesion regressed spontaneously. The presentation in childhood is often nonspecific. MRI is the imaging modality of choice for diagnosing these lesions. Conservative treatment has to be considered in cases with a benign clinical course and provided that the patient is followed up neurologically with repeated MRI.

    In cariously exposed immature permanent teeth, the treatment choice is controversial in pediatric dentistry. Radical root canal treatment usually appears to be the solution for these teeth. Even partial pulpotomy is a vital treatment for traumatically exposed immature permanent teeth; extending the borders of indication towards cariously exposed immature permanent teeth with reversible pulpitis may abolish the necessity of pulpectomy. This article describes the partial pulpotomy of a cariously affected immature permanent teeth and the follow-up for 1 year. A healthy 11-year-old male patient was referred to Gazi University Faculty of Dentistry Department of Pediatric Dentistry. The patient had reversible pulpitis symptoms on teeth numbered 45. At radiographic examination, immature apex and deep caries lesion were observed and partial pulpotomy was performed by using calcium hydroxide to maintain vitality of the pulp and allow continued development of root dentin expecting the root will attain full maturity. Clinical and radiographic follow-up demonstrated a vital pulp besides not only closure of the apex (apexogenesis), but also physiologic root development (maturogenesis) after 1 year. Partial pulpotomy is an optional treatment for cariously exposed immature permanent teeth for preserving vitality and physiological root development. PMID:24324899

    In many non-human species, including primates, gestational reproductive hormones play an essential role in the onset of maternal motivation and behaviors. We investigated the associations between prepartum estradiol and progesterone and maternal behavior at 1-year postpartum in 177 women. Blood was obtained at five gestational time points and an index of quality of maternal care was determined using a well-validated mother-child interaction protocol. Women who exhibited higher quality maternal care at 1-year postpartum were characterized by unique gestational profiles of estradiol, progesterone and the estrogen to progesterone ratio; specifically by slower accelerations and levels of these hormone trajectories beginning in midgestation. Further, it appeared that both fetal sex and parity moderated these findings, with first time mothers and mothers of females showing stronger associations. In sum, these data document persisting associations between prepartum hormone profiles and human maternal behavior. More broadly, these findings add to the growing literature highlighting the perinatal period as one of critical neurodevelopment in the lifespan of the human female. PMID:27427279

    A 4-week, double-blind comparison of ketoconazole and placebo was conducted in sixty-six patients with tinea versicolor. Two hundred milligrams of ketoconazole in a daily oral dose was effective in producing a clinical and mycologic cure: lesions in thirty-three of thirty-four patients on active drug were completely healed (97%), and one patient had a mild residual effect. Only three patients on placebo were considered to have responded, and none experienced complete healing. Potassium hydroxide (KOH) examinations were negative in all but one of the patients given ketoconazole. All patients receiving ketoconazole who were KOH-negative at week 4 also showed negative results when reexamined 8 weeks later. Patients who did not respond (virtually all of the patients given placebo) were subsequently treated with a topical imidazole lotion. Safety evaluation, including blood chemistry tests and a comprehensive liver function battery, showed no differences between the ketoconazole and placebo groups. Ketoconazole was well tolerated and produced no significant adverse effects. Follow-up after 1 year revealed that 64% of patients given ketoconazole were still clear, whereas only 11% of patients who received placebo (later treated with imidazole topically) were clear after 1 year.

    The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], p<.01). When compared to non-spanked children, there was a 33% greater probability of subsequent CPS involvement for children who were spanked at age 1. Given the undesirable consequences of spanking children and a lack of empirical evidence to suggest positive effects of physical punishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life.

    In conjunction with a study on the biological effects of accelerated heavy ions on rat spinal cord, we were able to assess the residual skin damage remaining 1 year postirradiation. In this study, rats were irradiated with 230-kVp fractionated doses of either X rays, carbon ions, or neon ions. Four radiation fractions were given at daily intervals. For the carbon and neon ion exposures, rats were irradiated in both the plateau and spread Bragg peak (4 cm) regions of ionization. Comparing doses that produced complete epilation with a slight suggestion of a residual radiation scar, it was found that the relative biological effectivesness (RBE) values 1 year postirradiation for the four fraction irradiations were: carbon ions (plateau ionization region), 1.06; carbon ions (spread Bragg peak ionization region), 1.88; neon ions (plateau region of ionization), 1.55; and neon ions (spread Bragg peak ionization region), 2.26. RBE values for production of paralysis after spinal cord irradiation (using the same X-ray total dose levels for comparison purposes) were in all cases higher than the RBE values obtained from assessment of residual skin injury.

    Executive function declines with age, but engaging in aerobic exercise may attenuate decline. One mechanism by which aerobic exercise may preserve executive function is through the up-regulation of brain-derived neurotropic factor (BDNF), which also declines with age. The present study examined BDNF as a mediator of the effects of a 1-year walking intervention on executive function in 90 older adults (mean age = 66.82). Participants were randomized to a stretching and toning control group or a moderate intensity walking intervention group. BDNF serum levels and performance on a task-switching paradigm were collected at baseline and follow-up. We found that age moderated the effect of intervention group on changes in BDNF levels, with those in the highest age quartile showing the greatest increase in BDNF after 1-year of moderate intensity walking exercise (p = 0.036). The mediation analyses revealed that BDNF mediated the effect of the intervention on task-switch accuracy, but did so as a function of age, such that exercise-induced changes in BDNF mediated the effect of exercise on task-switch performance only for individuals over the age of 71. These results demonstrate that both age and BDNF serum levels are important factors to consider when investigating the mechanisms by which exercise interventions influence cognitive outcomes, particularly in elderly populations.

    A two-element site test interferometer has been deployed at the NASA Deep Space Network (DSN) tracking complex in Goldstone, California, since May 2007. The interferometer system consists of two offset-fed 1.2 m parabolic reflectors which monitor atmospheric-induced amplitude and phase fluctuations on an unmodulated beacon signal (20.199 GHz) broadcast from a geostationary satellite (Anik F2). The geometry of the satellite and the ground-based infrastructure imposes a 48.5 elevation angle with a separation distance of 256 m along an east-west baseline. The interferometer has been recording phase fluctuation data, to date, for 1 yr with an overall system availability of 95 percent. In this paper, we provide the cumulative distribution functions (CDFs) for 1 year of recorded data, including phase rms, spatial structure function exponent, and surface meteorological measurements: surface wind speed, relative humidity, temperature, barometric pressure, and rain rate. Correlation between surface measurements, phase rms, and amplitude rms at different time scales are discussed. For 1 year, phase fluctuations at the DSN site in Goldstone, are better than 23 for 90 percent of the time (at 48.5 elevation). This data will be used to determine the suitability of the Goldstone site as a location for the Next Generation Deep Space Network.

    OBJECTIVES: Early infant mortality has not declined as rapidly as child mortality in many countries. Identification of risk factors for early infant mortality may help inform the design of intervention strategies. METHODS: Over the period 1994-97, 15,469 live-born, singleton infants in rural Nepal were followed to 24 weeks of age to identify risk factors for mortality within 0-7 days, 8-28 days, and 4-24 weeks after the birth. FINDINGS: In multivariate models, maternal and paternal education reduced mortality between 4 and 24 weeks only: odds ratios (OR) 0.28 (95% confidence interval (CI) = 0.12-0.66) and 0.63 (95% CI = 0.44-0.88), respectively. Miscarriage in the previous pregnancy predicted mortality in the first week of life (OR = 1.98, 95% CI = 1.37-2.87), whereas prior child deaths increased the risk of post-neonatal death (OR = 1.85, 95% CI 1.24-2.75). A larger maternal mid-upper arm circumference reduced the risk of infant death during the first week of life (OR = 0.88, 95% CI = 0.81-0.95). Infants of women who did not receive any tetanus vaccinations during pregnancy or who had severe illness during the third trimester were more likely to die in the neonatal period. Maternal mortality was strongly associated with infant mortality (OR = 6.43, 95% CI = 2.35-17.56 at 0-7 days; OR = 11.73, 95% CI = 3.82-36.00 at 8-28 days; and OR = 51.68, 95% CI = 20.26-131.80 at 4-24 weeks). CONCLUSION: Risk factors for early infant mortality varied with the age of the infant. Factors amenable to intervention included efforts aimed at maternal morbidity and mortality and increased arm circumference during pregnancy. PMID:14758431

    Background and objective COPD is well known to frequently coexist with osteoporosis. Bone fractures often occur and may affect mortality in COPD patients. However, in-hospital mortality related to bone fractures in COPD patients has been poorly studied. This retrospective study investigated in-hospital mortality of COPD patients with bone fractures using a national inpatient database in Japan. Methods Data of COPD patients admitted with bone fractures, including hip, vertebra, shoulder, and forearm fractures to 1,165 hospitals in Japan between July 2010 and March 2013, were extracted from the Diagnosis Procedure Combination database. The clinical characteristics and mortalities of the patients were determined. Multivariable logistic regression analysis was also performed to determine the factors associated with in-hospital mortality of COPD patients with hip fractures. Results Among 5,975 eligible patients, those with hip fractures (n=4,059) were older, had lower body mass index (BMI), and had poorer general condition than those with vertebral (n=1,477), shoulder (n=281), or forearm (n=158) fractures. In-hospital mortality was 7.4%, 5.2%, 3.9%, and 1.3%, respectively. Among the hip fracture group, surgical treatment was significantly associated with lower mortality (adjusted odds ratio, 0.43; 95% confidence interval, 0.32–0.56) after adjustment for patient backgrounds. Higher in-hospital mortality was associated with male sex, lower BMI, lower level of consciousness, and having several comorbidities, including pneumonia, lung cancer, congestive heart failure, chronic liver disease, and chronic renal failure. Conclusion COPD patients with hip fractures had higher mortality than COPD patients with other types of fracture. Surgery for hip fracture was associated with lower mortality than conservative treatment. PMID:27703343

    Background 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. Objectives 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. Methods We examined heart disease and stroke mortality rates for the 6 largest Asian-American subgroups (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) from 2003–2010. U.S. death records were used to identify race/ethnicity and cause of death by ICD-10 coding. Using both U.S. Census and death record data, standardized mortality ratios (SMR), relative SMRs (rSMR), and proportional mortality ratios (PMR) were calculated for each sex and ethnic group relative to Non-Hispanic Whites (NHW). Results 10,442,034 death records were examined. While 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 to NHWs. Conclusions 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.

    with mental disorders (from 148 studies) was 2.22 (95% CI, 2.12–2.33). Of these, 135 studies revealed that mortality was significantly higher among people with mental disorders than among the comparison population. A total of 67.3% of deaths among people with mental disorders were due to natural causes, 17.5% to unnatural causes, and the remainder to other or unknown causes. The median years of potential life lost was 10 years (n = 24 studies). We estimate that 14.3% of deaths worldwide, or approximately 8 million deaths each year, are attributable to mental disorders. CONCLUSIONS AND RELEVANCE These estimates suggest that mental disorders rank among the most substantial causes of death worldwide. Efforts to quantify and address the global burden of illness need to better consider the role of mental disorders in preventable mortality. PMID:25671328

    In examining the relative importance of snakebite mortality in different parts of the world, the authors review the information collected concerning both snakebite mortality and the species of snake incriminated. Available statistical data are known to be unreliable and at best can serve to provide only an approximate and highly conservative estimate of the relative magnitude of the snakebite problem. The sources of error inherent in the data are discussed, and estimates are made of the probable mortality from snakebite in various areas of the world. PMID:13150169

    The rate of mortality of the zebra mussel in response to chlorine is described by a kinetic model that combines a statistical characterization of mussel mortality with a disinfection-type modeling approach. Parameter estimates were made with nine sets of data from experiments conducted in Niagara River water. From the kinetic model, an operational diagram was constructed that describes the time to 95% mortality as a function of chlorine concentration and temperature. Either the model or the diagram can be used to assist utilities in planning chlorination treatments for controlling zebra mussels.

    Abstract Repeat hospitalization due to acute heart failure (HF) is a global public health problem that markedly impacts on health resource use. Identifying novel predictors of rehospitalization would help physicians to determine the optimal postdischarge plan for preventing HF rehospitalization. Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for many heart diseases, including HF. We assessed whether NAFLD at hospital admission predicts 1-year all-cause rehospitalization in patients with acute HF. We enrolled all patients consecutively admitted for acute HF to our General Medicine Division, from January 2013 to April 2014, after excluding patients with acute myocardial infarction, severe heart valve diseases, malignancy, known liver diseases, and those with volume overload related to extracardiac causes. NAFLD was diagnosed by ultrasonography and exclusion of competing etiologies. The primary outcome of the study was the 1-year all-cause rehospitalization rate. Among the 107 patients enrolled in the study, the cumulative rehospitalization rate was 12.1% at 1 month, 25.2% at 3 months, 29.9% at 6 months, and 38.3% at 1 year. Patients with NAFLD had markedly higher 1-year rehospitalization rates than those without NAFLD (58% vs 21% at 1 y; P < 0.001 by the log-rank test). Cox regression analysis revealed that NAFLD was associated with a 5.5-fold increased risk of rehospitalization (adjusted hazard ratio 5.56, 95% confidence interval 2.46–12.1, P < 0.001) after adjustment for multiple HF risk factors and potential confounders. In conclusion, NAFLD was independently associated with higher 1-year rehospitalization in patients hospitalized for acute HF. PMID:26886619

    Background and Objectives Cerebrovascular disease is a leading cause of mortality and morbidity in Korea. Understanding of cerebrovascular disease mortality trends is important to reduce the health burden from cerebrovascular diseases. We examined the changing pattern of mortality related to cerebrovascular disease in Korea over 30 years from 1983 to 2012. Subjects and Methods Numbers of deaths from cerebrovascular disease, hemorrhagic stroke, and cerebral infarction were obtained from the national Cause of Death Statistics. Crude and age-adjusted mortality rates were calculated for men and women for each year. Penalized B-spline methods, which reduce bias and variability in curve fitting, were used to identify the trends of 30-year mortality and identify the year of highest mortality. Results During the 30 years, cerebrovascular disease mortality has markedly declined. The age-adjusted cerebrovascular disease mortality rate has decreased by 78% in men and by 68% in women. In the case of hemorrhagic stroke, crude mortality peaked in 2001 but age-adjusted mortality peaked in 1994. Between 1994 and 2012, age-adjusted mortality from hemorrhagic stroke has decreased by 68% in men and 59% in women. In the case of cerebral infarction, crude and age-adjusted mortality rates steeply increased until 2004 and 2003, respectively, and both rates decreased rapidly thereafter. Conclusion Cerebrovascular disease mortality rate has significantly decreased over the last 30 years in Korea, but remains a health burden. The prevalence of major cardiovascular risk factors are still highly prevalent in Korea. PMID:27482259

    Objective: Examining oral health and oral hygiene as predictors of subsequent one-year survival in the institutionalized elderly. Design: It was hypothesized that oral health would be related to mortality in an institutionalized geriatric population. A 12-month prospective study of 292 elderly residing in nine geriatric institutions in Granada, Spain, was thus carried out to evaluate the association between oral health and mortality. Independent samples, T-test, chi-square test and Cox regression analysis were used to analyze the data. Sixty-three participants died during the 12-month follow-up. Results: Mortality was increased in denture users (RR = 2.18, p= 0.007) and in people suffering severe cognitive impairment (RR = 2. 24, p= 0.003). One-year mortality was 50% in participants having both these characteristics. Conclusions: Oral hygiene was not significantly associated with mortality. Cognitive impairment and wearing dentures increased the risk of death. One-year mortality was 50% in cognitively impaired residents wearing dentures as opposed to 10% in patients without dentures and cognitive impairment. Key words:Oral health, mortality risk, institutionalised elderly. PMID:22322487

    Background The authors conducted a retrospective cohort mortality study on police officers from 1950-2005. Methods Standardized Mortality Ratio (SMR) analyses were conducted separately for white male (n=2761), black (n=286), and female (n=259) officers. Results Mortality from all causes of death combined for white male officers was significantly higher than expected (SMR=1.20; 95% confidence interval (CI) =1.14-1.26). Increased mortality was also seen for all malignant neoplasms combined (SMR=1.32; 1.19-1.46), all benign neoplasms combined (SMR=2.50; 1.08-4.93), and all diseases of the circulatory system combined (SMR=1.11; 1.02-1.19). The elevated mortality for all malignant neoplasms was primarily due to statistically significant excesses in cancers of the esophagus, colon, respiratory system, Hodgkin’s disease and leukemia. Black officers had lower than expected mortality from all causes (SMR=0.45; 0.18-0.92) while female officers had elevated all-cause mortality (SMR=2.17; 1.12-3.79). Conclusions Findings of increased risk for malignant neoplasms should be replicated and studied in relation to measured risk factors. PMID:26690719

    OBJECTIVES: This study examined trends and differentials in US childhood mortality from 1950 through 1993 according to sex, race/ethnicity, education, family income, and cause of death. METHODS: Log-linear, multiple regression, and Cox proportional hazards regression models were applied to the data from the National Vital Statistics System, the National Longitudinal Mortality Study, and the Area Resource File. RESULTS: Substantial declines in US childhood mortality have occurred in the past 4 decades, primarily due to decreases in mortality from unintentional injuries, cancer, pneumonia and influenza, and congenital anomalies. The overall declining trend, however, has been dampened by a twofold to threefold increase in the suicide and homicide rates among children since 1968. Male, Black, American Indian, Hawaiian, and Puerto Rican children and those in the lower socioeconomic strata were at an increased risk of death. CONCLUSIONS: Increasing trends in mortality from violence, firearm injuries, and human immunodeficiency virus/acquired immunodeficiency syndrome pose a major obstacle to continued declines in US childhood mortality. Reducing socioeconomic disparities and improving access to and use of health care may bring about further declines in overall and injury-related childhood mortality. PMID:8604780

    Objectives. We evaluated the independent and joint effects of race, individual socioeconomic status (SES), and neighborhood SES on mortality risk. Methods. We conducted a prospective analysis involving 52 965 non-Hispanic Black and 23 592 non-Hispanic White adults taking part in the Southern Community Cohort Study. Cox proportional hazards modeling was used to determine associations of race and SES with all-cause and cause-specific mortality. Results. In our cohort, wherein Blacks and Whites had similar individual SES, Blacks were less likely than Whites to die during the follow-up period (hazard ratio [HR] = 0.78; 95% confidence interval [CI] = 0.73, 0.84). Low household income was a strong predictor of all-cause mortality among both Blacks and Whites (HR = 1.76; 95% CI = 1.45, 2.12). Being in the lowest (vs highest) category with respect to both individual and neighborhood SES was associated with a nearly 3-fold increase in all-cause mortality risk (HR = 2.76; 95% CI = 1.99, 3.84). There was no significant mortality-related interaction between individual SES and neighborhood SES among either Blacks or Whites. Conclusions. SES is a strong predictor of premature mortality, and the independent associations of individual SES and neighborhood SES with mortality risk are similar for Blacks and Whites. PMID:25322291

    Objectives. We sought to test the hypothesis that providing help to others predicts a reduced association between stress and mortality. Methods. We examined data from participants (n = 846) in a study in the Detroit, Michigan, area. Participants completed baseline interviews that assessed past-year stressful events and whether the participant had provided tangible assistance to friends or family members. Participant mortality and time to death was monitored for 5 years by way of newspaper obituaries and monthly state death-record tapes. Results. When we adjusted for age, baseline health and functioning, and key psychosocial variables, Cox proportional hazard models for mortality revealed a significant interaction between helping behavior and stressful events (hazard ratio [HR] = 0.58; P < .05; 95% confidence interval [CI] = 0.35, 0.98). Specifically, stress did not predict mortality risk among individuals who provided help to others in the past year (HR = 0.96; 95% CI = 0.79, 1.18), but stress did predict mortality among those who did not provide help to others (HR = 1.30; P < .05; 95% CI = 1.05, 1.62). Conclusions. Helping others predicted reduced mortality specifically by buffering the association between stress and mortality. PMID:23327269

    Objective: We estimated premature mortality and identified causes of death and associated factors in people with active convulsive epilepsy (ACE) in rural Kenya. Methods: In this prospective population-based study, people with ACE were identified in a cross-sectional survey and followed up regularly for 3 years, during which information on deaths and associated factors was collected. We used a validated verbal autopsy tool to establish putative causes of death. Age-specific rate ratios and standardized mortality ratios were estimated. Poisson regression was used to identify mortality risk factors. Results: There were 61 deaths among 754 people with ACE, yielding a rate of 33.3/1,000 persons/year. Overall standardized mortality ratio was 6.5. Mortality was higher across all ACE age groups. Nonadherence to antiepileptic drugs (adjusted rate ratio [aRR] 3.37), cognitive impairment (aRR 4.55), and age (50+ years) (rate ratio 4.56) were risk factors for premature mortality. Most deaths (56%) were directly related to epilepsy, with prolonged seizures/possible status epilepticus (38%) most frequently associated with death; some of these may have been due to sudden unexpected death in epilepsy (SUDEP). Possible SUDEP was the likely cause in another 7%. Conclusion: Mortality in people with ACE was more than 6-fold greater than expected. This may be reduced by improving treatment adherence and prompt management of prolonged seizures and supporting those with cognitive impairment. PMID:24443454

    Objective: To examine the relation between levels of patriarchy and male health by comparing female homicide rates with male mortality within countries. Hypothesis: High levels of patriarchy in a society are associated with increased mortality among men. Design: Cross sectional ecological study design. Setting: 51 countries from four continents were represented in the data—America, Europe, Australasia, and Asia. No data were available for Africa. Results: A multivariate stepwise linear regression model was used. Main outcome measure was age standardised male mortality rates for 51 countries for the year 1995. Age standardised female homicide rates and GDP per capita ranking were the explanatory variables in the model. Results were also adjusted for the effects of general rates of homicide. Age standardised female homicide rates and ranking of GDP were strongly correlated with age standardised male mortality rates (Pearson's r = 0.699 and Spearman's 0.744 respectively) and both correlations achieved significance (p<0.005). Both factors were subsequently included in the stepwise regression model. Female homicide rates explained 48.8% of the variance in male mortality, and GDP a further 13.6% showing that the higher the rate of female homicide, and hence the greater the indicator of patriarchy, the higher is the rate of mortality among men. Conclusion: These data suggest that oppression and exploitation harm the oppressors as well as those they oppress, and that men's higher mortality is a preventable social condition, which could be tackled through global social policy measures.

    Background Infant mortality rates in the US exceed those in all other developed countries and in many less developed countries, suggesting political factors may contribute. Methods Annual time series on overall, White and Black infant mortality rates in the US were analysed over the 1965–2010 time period to ascertain whether infant mortality rates varied across presidential administrations. Data were de-trended using cubic splines and analysed using both graphical and time series regression methods. Results Across all nine presidential administrations, infant mortality rates were below trend when the President was a Democrat and above trend when the President was a Republican. This was true for overall, neonatal and postneonatal mortality. Regression estimates show that, relative to trend, Republican administrations were characterized by infant mortality rates that were, on average, 3% higher than Democratic administrations. In proportional terms, effect size is similar for US Whites and Blacks. US Black rates are more than twice as high as White, implying substantially larger absolute effects for Blacks. Conclusions We found a robust, quantitatively important association between net of trend US infant mortality rates and the party affiliation of the president. There may be overlooked ways by which macro-dynamics of policy impact microdynamics of physiology, suggesting the political system is a component of the underlying mechanism generating health inequality in the USA.

    2014-01-01

    Objectives. We analyzed how recessions and job loss jointly shape mortality risks among older US adults. Methods. We used data for 50 states from the Health and Retirement Study and selected individuals who were employed at ages 45 to 66 years during 1992 to 2011. We assessed whether job loss affects mortality risks, whether recessions moderate the effect of job loss on mortality, and whether individuals who do and do not experience job loss are differentially affected by recessions. Results. Compared with individuals not experiencing job loss, mortality risks among individuals losing their job in a recession were strongly elevated (hazard ratio = 1.6; 95% confidence interval = 1.1, 2.3). Job loss during normal times or booms is not associated with mortality. For employed workers, we found a reduction in mortality risks if local labor market conditions were depressed, but this result was not consistent across different model specifications. Conclusions. Recessions increase mortality risks among older US adults who experience job loss. Health professionals and policymakers should target resources to this group during recessions. Future research should clarify which health conditions are affected by job loss during recessions and whether access to health care following job loss moderates this relation. PMID:25211731

    Serum albumin had been noted to be a predictor of mortality in hemodialysis (HD) patients. Normalized protein catabolic rate (nPCR) less than 0.8 or greater than 1.4 g/kg/d was also associated with greater mortality. There was no previous study to show the effectiveness of combination of serum albumin and nPCR to predict the mortality in chronic HD patients. Eight hundred and sixty-six patients were divided into 4 groups according to their nPCR and serum albumin levels. Biochemical, and hematological parameters were recorded. The associations between groups, variables mentioned above and mortality were analyzed. Multivariate Cox regression analysis showed that age, diabetes mellitus, fistula as blood access, nPCR <1.2 g/kg/day combined with albumin <4 (Group A), nPCR ≧ 1.2 g/kg/day combined with albumin <4 g/dL (Group B) (nPCR ≧ 1.2 g/kg/day combined with Albumin ≧ 4 g/dL as reference group), non-anuria, hemoglobin, creatinine, and log (high sensitivity C reactive protein) were correlated with 36 months mortality. Group A and group B patients had higher 36 months cardiovascular (CV) and infection related mortality rates as compared with group D patients. In conclusion, Group A and Group B patients had significantly higher rate of all-cause, CV and infection related mortality. PMID:27752119

    STUDY OBJECTIVE--The aim was to analyse trends in "avoidable" mortality in Sweden, and to contribute to the methodology of avoidable mortality as an index of the quality of care. SETTING AND PARTICIPANTS--All deaths of Swedish citizens and other residents in Sweden during the period 1974-1985 were analysed as to causes of death between ages 0 and 64 years. MEASUREMENTS AND MAIN RESULTS--Total mortality delined during the 12 year period studied. Avoidable causes of death were grouped into preventable and treatable causes according to Rutstein's classification. In men, treatable diseases declined more during the 12 year period studied than did total mortality. When lung cancer was excluded, preventable diseases declined for both sexes. Certain avoidable causes of death decreased compared to total mortality, while some others showed an increase. The death rate increased for some avoidable causes of death such as pneumonia other than viral. In women death rates increased for chronic bronchitis and emphysema as well as for malignant neoplasms of trachea, bronchus, and lung, while for boys aged 1-14 years bronchitis NOS and asthma showed an increasing death rate. CONCLUSIONS--The study indicates that the avoidable mortality method is sensitive enough to describe important changes in the mortality pattern. The explicit definition of treatable and preventable causes of death constitutes a methodological development in epidemiological analysis of this type. Further studies on the quality of care should combine this method with other methods examining the structure and process of health care. PMID:1479317

    We have updated the follow-up of cancer mortality for a cohort study of man-made vitreous fiber production workers from Denmark, Finland, Norway, Sweden, United Kingdom, Germany, and Italy, from 1982 to 1990. In the mortality analysis, 22,002 production workers contributed 489,551 person-years, during which there were 4,521 deaths. Workers with less than 1 year of employment had an increased mortality [standardized mortality ratio (SMR) = 1.45; 95% confidence interval (CI) = 1.37-1.53]. Workers with 1 year or more of employment, contributing 65% of person-years, had an SMR of 1.05 (95% CI = 1.02-1.09). The SMR for lung cancer was 1.34 (95% CI = 1.08-1.63, 97 deaths) among rock/slag wool workers and 1.27 (95% CI = 1.07-1.50, 140 deaths) among glass wool workers. In the latter group, no increase was present when local mortality rates were used. Among rock/slag wool workers, the risk of lung cancer increased with time-since-first-employment and duration of employment. The trend in lung cancer mortality according to technologic phase at first employment was less marked than in the previous follow-up. We obtained similar results from a Poisson regression analysis limited to rock/slag wool workers. Five deaths from pleural mesothelioma were reported, which may not represent an excess. There was no apparent excess for other categories of neoplasm. Tobacco smoking and other factors linked to social class, as well as exposures in other industries, appear unlikely to explain the whole increase in lung cancer mortality among rock/slag wool workers. Limited data on other agents do not indicate an important role of asbestos, slag, or bitumen. These results are not sufficient to conclude that the increased lung cancer risk is the result of exposure to rock/slag wool; however, insofar as respirable fibers were an important component of the ambient pollution of the working environment, they may have contributed to the increased risk.

    The present study addresses the consequences of cognitive disturbances on symptomatic outcome. Fifty-three first-episode schizophrenics were reassessed (n = 32) 1 year after admission. Simple regression analyses revealed that several self-perceived cognitive deficits at baseline as measured with the Frankfurt Complaint Questionnaire significantly predicted increased Brief Psychiatric Rating Scale global scores at follow-up (p = 0.05 to p = 0.005). A stepwise regression analysis proved memory dysfunction to be the strongest predictor of symptomatic worsening (p = 0.005). It is suggested that the exploration and treatment of neuropsychological deficits in schizophrenia is of great clinical importance with regard to its impact on both functional and symptomatic outcome in schizophrenia.

    The incidence of whooping cough in Romania is substantially underestimated, and, as noted by the health authorities, this is mostly due to the lack of both awareness and biological diagnosis. We conducted a 1-year study in Bucharest in order to assess the circulation of Bordetella pertussis, the main etiological agent of whooping cough. Fifty-one subjects suspected of whooping cough were enrolled. Culture, real-time PCR, and enzyme-linked immunosorbent assay were used for laboratory diagnosis. Whooping cough patients (63%) were distributed among all age groups, and most were unvaccinated, incompletely vaccinated, or had been vaccinated more than 5 years previously. Bordetella holmesii DNA was detected in 22% of the bordetellosis cases; these patients included adults; teenagers; and, surprisingly, young children. B. pertussis isolates were similar to the clinical isolates currently circulating elsewhere in Europe. One isolate does not express pertactin, an antigen included in some acellular pertussis vaccines.

    The Bayley Scales of Infant Development were administered at 1 year of age to 54 healthy infants of adolescent mothers. Information was obtained regarding maternal cognitive and emotional maturity, child-rearing attitudes, attitudes toward the infant, and psychosocial status at one year. The average Bayley Mental Scale score was 113, and the average Bayley Motor Scale score was 105. There was a negative correlation between the Bayley Mental Scale score and maternal age and education. Bayley Motor Scale scores were predictable from a combination of maternal authoritarian attitudes, abuse potential, and infant's birth weight. Although high authoritarian attitudes in mothers have been associated with poor cognitive development at later ages, they may represent an important strength in adolescent mothers during the first year.

    A case of eosinophilic granulomatous gastroenterocolitis and hepatitis in a 1-year-old male Siberian Husky is described. The dog presented with a history of diarrhea, weakness, lethargy, and anorexia of several months' duration. Hematologic and biochemical examinations, abdominal ultrasonography, computer tomography, and exploratory laparotomy were performed. Histopathologic examination of full-thickness biopsies from the gastrointestinal tract and liver revealed the presence of eosinophilic granulomatous lesions in the submucosa and tunica muscularis of stomach, jejunum, ileum, colon, and liver. Infectious agents were not detected by light microscopic and electron microscopic examination or by immunohistochemistry. On the basis of the findings, it is concluded that the disease in this dog represents an unusual manifestation of chronic idiopathic inflammatory bowel disease.

    Records of 170 sandhill cranes (Grus canadensis) necropsied at the National Wildlife Health Research Center, Wisconsin, from 1976 through 1985 were reviewed as representative samples to determine causes of nonhunting mortality in the mid-continent and Rocky Mountain populations of sandhill cranes. Avian cholera, avian botulism, and ingestion of mycotoxins were leading causes of nonhunting mortality. Hailstorms, lightning, lead poisoning, predation, avian tuberculosis, and collisions with power lines also killed cranes.

    Renal denervation (RDN) reduces muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in resistant hypertension. Although a persistent BP-lowering effect has been demonstrated, the long-term effect on MSNA remains elusive. We investigated whether RDN influences MSNA over time. Office BP and MSNA were obtained at baseline, 3, 6, and 12 months after RDN in 35 patients with resistant hypertension. Office BP averaged 166±22/88±19 mm Hg, despite the use of an average of 4.8±2.1 antihypertensive drugs. Baseline MSNA was 51±11 bursts/min ≈2- to 3-fold higher than the level observed in healthy controls. Mean office systolic and diastolic BP significantly decreased by -12.6±18.3/-6.5±9.2, -16.1±25.6/-8.6±12.9, and -21.2±29.1/-11.1±12.9 mm Hg (P<0.001 for both systolic BP and diastolic BP) with RDN at 3-, 6-, and 12-month follow-up, respectively. MSNA was reduced by -8±12, -6±12, and -6±11 bursts/min (P<0.01) at 3-, 6-, and 12-month follow-up. The reduction in MSNA was maintained, despite a progressive fall in BP over time. No such changes were observed in 7 control subjects at 6-month follow-up. These findings confirm previous reports on the favorable effects of RDN on elevated BP and demonstrate sustained reduction of central sympathetic outflow ≤1-year follow-up in patients with resistant hypertension and high baseline MSNA. These observations are compatible with the hypothesis of a substantial contribution of afferent renal nerve signaling to increased BP in resistant hypertension and argue against a relevant reinnervation at 1 year after procedure.

    Enteroaggregative Escherichia coli (EAEC) has been associated with persistent diarrhea, reduced growth acceleration, and failure to thrive in children living in developing countries and with childhood diarrhea in general in industrialized countries. The clinical implications of an EAEC carrier-status in children in industrialized countries warrants clarification. To investigate the pathological significance of an EAEC carrier-state in the industrialized countries, we designed a 1-year dynamic cohort study and performed follow-up every second month, where the study participants submitted a stool sample and answered a questionnaire regarding gastrointestinal symptoms and exposures. Exposures included foreign travel, consumption of antibiotics, and contact with a diseased animal. In the capital area of Denmark, a total of 179 children aged 0–6 years were followed in a cohort study, in the period between 2009 and 2013. This is the first investigation of the incidence and pathological significance of EAEC in Danish children attending daycare facilities. Conventional microbiological detection of enteric pathogens was performed at Statens Serum Institute, Copenhagen, Denmark, and at Hvidovre Hospital, Copenhagen, Denmark. Parents completed questionnaires regarding gastrointestinal symptoms. The EAEC strains were further characterized by serotyping, phylogenetic analysis, and susceptibility testing. EAEC was detected in 25 (14%) of the children during the observational period of 1 year. One or more gastrointestinal symptoms were reported from 56% of the EAEC-positive children. Diarrhea was reported in six (24%) of the EAEC positive children, but no cases of weight loss, and general failure to thrive were observed. The EAEC strains detected comprised a large number of different serotypes, confirming the genetic heterogeneity of this pathotype. EAEC was highly prevalent (n = 25, 14%) in Danish children in daycare centers and was accompanied by gastrointestinal symptoms in

    Objective Sleep duration is known to significantly affect health in adults and children, but little is understood about long-term associations. This prospective cohort study is the first to examine whether childhood sleep duration is associated with lifelong mortality risk. Methods Data from childhood were refined and mortality data collected for 1,145 participants from the Terman Life Cycle Study. Participants were born between 1904 and 1915, lived to at least 1940, and had complete age, bedtime, and waketime data at initial data collection (1917–1926). Homogeneity of the cohort sample (intelligent, mostly white) limits generality but provides natural control of common confounds. Through 2009, 1,039 participants had confirmed deaths. Sleep duration was calculated as the difference between each child’s bed and wake times. Age-adjusted sleep (deviation from that predicted by age) was computed. Cox proportional hazards survival models evaluated childhood sleep duration as a predictor of mortality separately by sex, controlling for baseline age. Results For males, a quadratic relation emerged: male children who under-slept or over-slept compared to peers were at increased risk of lifelong all-cause mortality (HR = 1.15, CI = 1.05 – 1.27). Effect sizes were smaller and non-significant in females (HR = 1.02, CI = 0.91 – 1.14). Conclusions Male children with shorter or longer sleep durations than expected for their age were at increased risk of death at any given age in adulthood. The findings suggest that sleep may be a core biobehavioral trait, with implications for new models of sleep and health throughout the entire lifespan. PMID:24588628

Objective Assess association of CgA levels and mortality risk of severely septic patients. Methods Serum CgA levels were measured in 50 hospitalized, severely septic patients with organ failure <48 hours. Results Higher CgA levels trended towards higher ICU and hospital mortality. Patients without cardiovascular disease who died in the ICU had higher median (IQR) CgA levels 602.3 (343.3, 1134.3) ng/ml vs. 205.5 (130.7, 325.9) ng/ml, p=0.01.

    Objective To assess associations between maternal child marriage (marriage before age 18) and morbidity and mortality of infants and children under 5 in India. Design Cross-sectional analyses of nationally representative household sample. Generalised estimating equation models constructed to assess associations. Adjusted models included maternal and child demographics and maternal body mass index as covariates. Setting India. Population Women aged 15-49 years (n=124 385); data collected in 2005-6 through National Family Health Survey-3. Data about child morbidity and mortality reported by participants. Analyses restricted to births in past five years reported by ever married women aged 15-24 years (n=19 302 births to 13 396 mothers). Main outcome measures In under 5s: mortality related infectious diseases in the past two weeks (acute respiratory infection, diarrhoea); malnutrition (stunting, wasting, underweight); infant (age <1 year) and child (1-5 years) mortality; low birth weight (<2500 kg). Results The majority of births (73%; 13 042/19 302) were to mothers married as minors. Although bivariate analyses showed significant associations between maternal child marriage and infant and child diarrhoea, malnutrition (stunted, wasted, underweight), low birth weight, and mortality, only stunting (adjusted odds ratio 1.22, 95% CI 1.12 to 1.33) and underweight (1.24, 1.14 to 1.36) remained significant in adjusted analyses. We noted no effect of maternal child marriage on health of boys versus girls. Conclusions The risk of malnutrition is higher in young children born to mothers married as minors than in those born to women married at a majority age. Further research should examine how early marriage affects food distribution and access for children in India. PMID:20093277

    Background Estimates of the effectiveness of neurofeedback as a treatment for attention-deficit hyperactivity disorder (ADHD) are mixed. Aims To investigate the long-term additional effects of neurofeedback (NFB) compared with treatment as usual (TAU) for adolescents with ADHD. Method Using a multicentre parallel-randomised controlled trial design, 60 adolescents with a DSM-IV-TR diagnosis of ADHD receiving NFB+TAU (n=41) or TAU (n=19) were followed up. Neurofeedback treatment consisted of approximately 37 sessions of theta/sensorimotor rhythm (SMR)-training on the vertex (Cz). Outcome measures included behavioural self-reports and neurocognitive measures. Allocation to the conditions was unmasked. Results At 1-year follow-up, inattention as reported by adolescents was decreased (range ηp2=0.23–0.36, P<0.01) and performance on neurocognitive tasks was faster (range ηp2=0.20–0.67, P<0.005) irrespective of treatment group. Conclusions Overall, NFB+TAU was as effective as TAU. Given the absence of robust additional effects of neurofeedback in the current study, results do not support the use of theta/SMR neurofeedback as a treatment for adolescents with ADHD and comorbid disorders in clinical practice.

    Objective: Despite widespread use, there is little data investigating the long-term impact of micronutrients on psychiatric disorders. This study investigated the naturalistic outcome 1-year post-baseline of a randomized controlled trials (RCT) that compared micronutrients with placebo in 80 adults with ADHD. Method: All participants were contacted and clinician-rated questionnaires completed. Results: A total of 72 (90%) of the sample participated; although there was significant regression in psychiatric functioning from the end-of-trial on all measures, outcomes remained significantly improved from baseline. Dominant treatment from the end-of-treatment to follow-up was investigated as a mediator of outcome; those staying on the micronutrients performed better than those who switched to medications or discontinued micronutrients. Cost was the most substantial reason why people stopped micronutrient treatment. Conclusion: For the small number of participants who stayed on micronutrients, the benefits conferred through the controlled trial were maintained. The results are limited by small sample, lack of blinding, expectation, and reliance on self-report of symptoms. PMID:24804687

    Background: There is limited research examining beverage habits, one of the most habitual dietary behaviors, with mortality risk. Objective: This study examined the association between coffee, black and green tea, sugar-sweetened beverages (soft drinks and juice), and alcohol and all-cause and cause-specific mortality. Methods: A prospective data analysis was conducted with the use of the Singapore Chinese Health Study, including 52,584 Chinese men and women (aged 45–74 y) free of diabetes, cardiovascular disease (CVD), and cancer at baseline (1993–1998) and followed through 2011 with 10,029 deaths. Beverages were examined with all-cause and cause-specific (cancer, CVD, and respiratory disease) mortality risk with the use of Cox proportional hazards regression. Results: The associations between coffee, black tea, and alcohol intake and all-cause mortality were modified by smoking status. Among never-smokers there was an inverse dose-response association between higher amounts of coffee and black tea intake and all-cause, respiratory-related, and CVD mortality (black tea only). The fully adjusted HRs for all-cause mortality for coffee for <1/d, 1/d, and ≥2/d relative to no coffee intake were 0.89, 0.86, and 0.83, respectively (P-trend = 0.0003). For the same black tea categories the HRs were 0.95, 0.90, and 0.72, respectively (P-trend = 0.0005). Among ever-smokers there was no association between coffee or black tea and the outcomes. Relative to no alcohol, light to moderate intake was inversely associated with all-cause mortality (HR: 0.87; 95% CI: 0.79, 0.96) in never-smokers with a similar magnitude of association in ever-smokers. There was no association between heavy alcohol intake and all-cause mortality in never-smokers and a strong positive association in ever-smokers (HR: 1.56; 95% CI: 1.40, 1.74). Green tea and sugar-sweetened beverages were not associated with all-cause or cause-specific mortality. Conclusions: Higher coffee and black tea intake was

    Importance Some evidence suggests vegetarian dietary patterns may be associated with reduced mortality, but the relationship is not well established. Objective To evaluate the association between vegetarian dietary patterns and mortality. Design Prospective cohort study; mortality analysis by Cox proportional hazards regression, controlling for important demographic and lifestyle confounders. Setting Adventist Health Study 2 (AHS-2), a large North American cohort. Participants A total of 96 469 Seventh-day Adventist men and women recruited between 2002 and 2007, from which an analytic sample of 73 308 participants remained after exclusions. Exposures Diet was assessed at baseline by a quantitative food frequency questionnaire and categorized into 5 dietary patterns: nonvegetarian, semi-vegetarian, pesco-vegetarian, lacto-ovo–vegetarian, and vegan. Main Outcome and Measure The relationship between vegetarian dietary patterns and all-cause and cause-specific mortality; deaths through 2009 were identified from the National Death Index. Results There were 2570 deaths among 73 308 participants during a mean follow-up time of 5.79 years. The mortality rate was 6.05 (95% CI, 5.82–6.29) deaths per 1000 person-years. The adjusted hazard ratio (HR) for all-cause mortality in all vegetarians combined vs non-vegetarians was 0.88 (95% CI, 0.80–0.97). The adjusted HR for all-cause mortality in vegans was 0.85 (95% CI, 0.73–1.01); in lacto-ovo–vegetarians, 0.91 (95% CI, 0.82–1.00); in pesco-vegetarians, 0.81 (95% CI, 0.69–0.94); and in semi-vegetarians, 0.92 (95% CI, 0.75–1.13) compared with nonvegetarians. Significant associations with vegetarian diets were detected for cardiovascular mortality, noncardiovascular noncancer mortality, renal mortality, and endocrine mortality. Associations in men were larger and more often significant than were those in women. Conclusions and Relevance Vegetarian diets are associated with lower all-cause mortality and with some

    Background Testosterone deficiency in patients with heart failure (HF) is associated with decreased exercise capacity and mortality; however, its impact on hospital readmission rate is uncertain. Furthermore, the relationship between testosterone deficiency and sympathetic activation is unknown. Objective We investigated the role of testosterone level on hospital readmission and mortality rates as well as sympathetic nerve activity in patients with HF. Methods Total testosterone (TT) and free testosterone (FT) were measured in 110 hospitalized male patients with a left ventricular ejection fraction < 45% and New York Heart Association classification IV. The patients were placed into low testosterone (LT; n = 66) and normal testosterone (NT; n = 44) groups. Hypogonadism was defined as TT < 300 ng/dL and FT < 131 pmol/L. Muscle sympathetic nerve activity (MSNA) was recorded by microneurography in a subpopulation of 27 patients. Results Length of hospital stay was longer in the LT group compared to in the NT group (37 ± 4 vs. 25 ± 4 days; p = 0.008). Similarly, the cumulative hazard of readmission within 1 year was greater in the LT group compared to in the NT group (44% vs. 22%, p = 0.001). In the single-predictor analysis, TT (hazard ratio [HR], 2.77; 95% confidence interval [CI], 1.58–4.85; p = 0.02) predicted hospital readmission within 90 days. In addition, TT (HR, 4.65; 95% CI, 2.67–8.10; p = 0.009) and readmission within 90 days (HR, 3.27; 95% CI, 1.23–8.69; p = 0.02) predicted increased mortality. Neurohumoral activation, as estimated by MSNA, was significantly higher in the LT group compared to in the NT group (65 ± 3 vs. 51 ± 4 bursts/100 heart beats; p < 0.001). Conclusion These results support the concept that LT is an independent risk factor for hospital readmission within 90 days and increased mortality in patients with HF. Furthermore, increased MSNA was observed in patients with LT. PMID:26200897

    Background The National Kidney Foundation–Kidney Disease Outcomes Quality Initiative recommends that the serum aluminum level (SAL) should be below 20 µg/L for patients with maintenance hemodialysis (MHD). However, serum aluminum may have toxic effects on MHD patients even when it is in the apparently acceptable range (below 20 µg/L). Methods The Medical Ethics Committee approved this study. Initially, 954 MHD patients in dialysis centers were recruited. A total of 901 patients met the inclusion criteria and were followed-up for 1 year. Patients were stratified by SAL into four equal-sized groups: first quartile (<6 µg/L), second quartile (6–9 µg/L), third quartile (9–13 µg/L), and fourth quartile (>13 µg/L). Demographic, biochemical, and dialysis-related data were obtained for analyses. A linear regression model was applied to identify factors associated with SAL. Cox proportional hazard model was used to determine the significance of variables in prediction of mortality. Results Only 9.3% of MHD patients had SALs of 20 µg/L or more. At the end of the follow-up, 54 patients (6%) died, and the main cause of death was cardiovascular disease. Kaplan–Meier survival analysis showed that patients in the fourth SAL quartile had higher mortality than those in the first SAL quartile (log rank test, χ2=13.47, P=0.004). Using the first quartile as reference, Cox multivariate analysis indicated that patients in the third quartile (hazard ratio =1.31, 95% confidence interval =1.12–1.53, P=0.038) and the fourth quartile (hazard ratio =3.19, 95% confidence interval =1.08–8.62, P=0.048) had increased risk of all-cause mortality. Conclusion This study demonstrates that SAL, even when in an apparently acceptable range (below 20 µg/L), is associated with increased mortality in MHD patients. The findings suggest that avoiding exposure of aluminum as much as possible is warranted for MHD patients.

    Background and Methods Crohn’s disease causes intestinal inflammation leading to intestinal fibrosis. Spironolactone is an anti-fibrotic medication commonly used in heart failure to reduce mortality. We examined whether spironolactone is anti-fibrotic in the context of intestinal inflammation. In vitro, spironolactone repressed fibrogenesis in TGFβ-stimulated human colonic myofibroblasts. However, spironolactone therapy significantly increased mortality in two rodent models of inflammation-induced intestinal fibrosis, suggesting spironolactone could be harmful during intestinal inflammation. Since IBD patients rarely receive spironolactone therapy, we examined whether spironolactone use was associated with mortality in a common cause of inflammatory colitis, Clostridium difficile infection (CDI). Results Spironolactone use during CDI infection was associated with increased mortality in a retrospective cohort of 4008 inpatients (15.9% vs. 9.1%, n=390 deaths, p<0.0001). In patients without liver disease, the adjusted OR for inpatient mortality associated with 80 mg spironolactone was 1.99 (95% CI: 1.51 – 2.63) In contrast to the main effect of spironolactone mortality, multivariable modeling revealed a protective interaction between liver disease and spironolactone dose. The adjusted odds ratio for mortality after CDI was 1.96 (95% CI: 1.50 – 2.55) for patients without liver disease on spironolactone vs. 1.28 (95% CI: 0.82 – 2.00) for patients with liver disease on spironolactone, when compared to a reference group without liver disease or spironolactone use. Conclusions We propose that discontinuation of spironolactone in patients without liver disease during CDI could reduce hospital mortality by 2-fold, potentially reducing mortality from CDI by 35,000 patients annually across Europe and the US.

    Background A relatively high early mortality rate (<30 days post-injury) for cervical spinal cord injury (SCI) has been observed. Objective To investigate this early mortality rate observed after cervical SCI and analyze the associated influential factors. Methods Medical records for 1163 patients with cervical SCI were reviewed, and the number of patients with early mortality was documented. Through logistic regression analysis, the effects of age, gender, occupation, cause of injury, severity of injury, highest involved spinal cord segment, nutritional condition during hospitalization, surgical treatment, tracheotomy, etc., on early mortality were assessed. Implementation of early treatment (i.e. surgery, tracheotomy, and nutritional support) and its effect on patient prognosis were also analyzed. Results Early mortality occurred in 109 of 1163 patients (9.4%). Four factors affected the early mortality rate, including level and severity of SCI, whether or not surgery was performed, the time interval between SCI and surgery, malnutrition, and tracheotomy. Patients with an American Spinal Injury Association grade of A, a high cervical SCI (C1–C3), and/or no surgical intervention were statistically more likely to have early mortality (P < 0.001). Conclusion Severe cervical SCI, upper-level cervical cord injury, malnutrition, and inappropriate tracheotomy are risk factors for early mortality in patients with cervical SCI. Surgery can reduce early mortality. Early tracheotomy should be performed in patients with complete upper-level cervical SCI, but patients with incomplete cervical SCI or complete low-level cervical SCI should initially be treated surgically to maintain smooth airway flow.

    The aim of this study was to determine whether soccer could have different bone benefits in prepubescent and pubescent boys. We investigated 76 boys aged 10 to 13 years during a 1-year study. All boys were prepubescent at the beginning of the study (T0); pubescent status was determined by a complete 24-h urine hormonal assay of FSH-LH, with LH ≤ 0.31 IU/24 h and FSH ≤ 2.19 IU/24 h corresponding to prepubescent Tanner stage I and with 0.31 < LH < 0.95 IU/24 h and 1.57 < FSH < 3.77 IU/24 h corresponding to pubescent Tanner stage II. At the end of the study (T1), 35 boys remained prepubescent (22 soccer players (F1) and 13 controls (C1)), and 41 boys had entered puberty (26 soccer players (F2) and 15 controls (C2)). Soccer players completed 2 to 5 h of training plus one competition game per week during the school year, and controls only had physical education at school. Bone mineral content (BMC) was measured at T0 and T1 by DPX in the lumbar spine, total hip, and whole body (WB) for a comparison between soccer players and controls. At T0, no BMC difference was found between F1 and C1, but BMC was higher in F2 than C2 in WB and weight-bearing sites. At T1, BMC was higher in WB and weight-bearing sites in both F1 and F2 compared to their respective controls. Between T0 and T1, soccer induced a BMC gain at weight-bearing sites in both F1 and F2 compared to C1 and C2, respectively. The soccer-related bone gain was greater in WB and weight-bearing (the lumbar spine, total hip, and supporting leg) and non-weight-bearing bones (dominant arm and nondominant arm) in boys who became pubescent than in boys who remained prepubescent. In conclusion, 1-year study in young male soccer players demonstrates that the process of bone accretion at the very early phase of puberty is more intensely stimulated by the combination of physical exercise and sexual impregnation than by one of these factors alone.

    OBJECTIVE: To present estimates of maternal mortality in 188 countries, areas, and territories for 1995 using methodologies that attempt to improve comparability. METHODS: For countries having data directly relevant to the measurement of maternal mortality, a variety of adjustment procedures can be applied depending on the nature of the data used. Estimates for countries lacking relevant data may be made using a statistical model fitted to the information from countries that have data judged to be of good quality. Rather than estimate the Maternal Mortality Ratio (MMRatio) directly, this model estimates the proportion of deaths of women of reproductive age that are due to maternal causes. Estimates of the number of maternal deaths are then obtained by applying this proportion to the best available figure of the total number of deaths among women of reproductive age. FINDINGS: On the basis of this exercise, we have obtained a global estimate of 515,000 maternal deaths in 1995, with a worldwide MMRatio of 397 per 100,000 live births. The differences, by region, were very great, with over half (273,000 maternal deaths) occurring in Africa (MMRatio: > 1000 per 100,000), compared with a total of only 2000 maternal deaths in Europe (MMRatio: 28 per 100,000). Lower and upper uncertainty bounds were also estimated, on the basis of which the global MMRatio was unlikely to be less than 234 or more than 635 per 100,000 live births. These uncertainty bounds and those of national estimates are so wide that comparisons between countries must be made with caution, and no valid conclusions can be drawn about trends over a period of time. CONCLUSION: The MMRatio is thus an imperfect indicator of reproductive health because it is hard to measure precisely. It is preferable to use process indicators for comparing reproductive health between countries or across time periods, and for monitoring and evaluation purposes. PMID:11285661

    The objectives of the study were to investigate mortality and causes of death in patients with recent-onset systemic lupus erythematosus (SLE) in Finland. Data for patients with SLE for the study were collected (2000-2007) from the nationwide register on decisions of special reimbursements for drugs, maintained by the Social Insurance Institution (SII) in Finland. Data on deaths of the patients were obtained from the official death certificate statistics of Statistics Finland until the end of 2008. Of the 566 incident SLE patients, median follow-up time was 5.4 (IQR 3.3, 7.1) years, and 30 patients (23 females, seven males) died in the years 2000 through 2008. Mean age at death was 67.8 ± 17.2 years for females and 62.3 ± 15.2 years for males. The 5-year survival rates were 94.8% (95%CI 92.0-96.6%) and 88.2% (95%CI 76.5-94.3%), respectively. The age- and sex-adjusted standardized mortality ratio was 1.48 (95%CI 1.01-2.12). Primary causes of death were cardiovascular diseases, malignancy and SLE itself. In conclusion, survival of the patients with SLE was inferior to that of the general population. Cardiovascular diseases were responsible for 37% of deaths.

    In a community-based intervention trial to reduce childhood mortality from pneumonia the intervention area included 58 villages (6176 children aged 0-4 years) and the control area 44 villages (3947 children) in Gadchiroli, India. The interventions included mass education about childhood pneumonia and case-management of pneumonia by paramedics, village health workers, and traditional birth attendants (TBAs) who were trained to recognise childhood pneumonia and treat it with co-trimoxazole. Parents sought treatment, and coverage was 76% without active case-detection efforts. The case-fatality rate among the 612 cases treated by health workers was 0.8%, compared with 13.5% in the control area. After a year of intervention pneumonia-specific childhood mortality was significantly lower in the intervention than in the control area (8.1 vs 17.5 deaths per 1000 children under 5 years); the difference between the areas was greatest in children under 1 year. The differences in infant mortality (89 vs 121 per 1000) and total under-5 mortality (28.5 vs 40.7 per 1000) were highly significant. Mortality from other causes remained similar in the two areas but neonatal mortality due to birth injury and prematurity was significantly lower in the intervention area, presumably owing to the combination of better maternal and neonatal care by the TBAs trained in the project and the availability of treatment for pneumonia. The cost of co-trimoxazole was US $0.025 per child per year ($2.64 per child saved). PMID:1973770

    Aim: To define the prognostic value of Doppler ultrasonographic morphology of ductus venosus (DV) waveform on canine neonatal mortality. Materials and Methods: Fifty-four healthy pregnant bitches underwent fetal ultrasonographic assessment. The DV waveforms were classified as diphasic (dDVw) or triphasic (tDVw) and compared with neonatal mortality. Results: Ninety-three fetuses were evaluated. Twenty fetuses belonged to litters with neonatal mortality, in which tDVw was observed. Seven fetuses belonged to litters without neonatal mortality, in which tDVw was observed. Fifty-eight fetuses belonged to litters without neonatal mortality, in which only dDVw was observed. Eight fetuses belonged to litters with neonatal mortality, in which only dDVw was observed. The correlation between tDVw and neonatal mortality was statistically significant (odds ratio [OR], 20.7; p<0.0001). Considering only pregnancies with one or two fetuses with the same DV waveform: Two fetuses with tDVw belonged to litters with neonatal mortality; 1 foetus with tDVw belonged to litter without neonatal mortality and 26 fetuses showed dDVw without neonatal mortality. The correlation between tDVw and neonatal mortality even in litters up to two pups was statistically significant (OR, 88.3; p=0.01). Conclusion: Echo-Doppler assessment of DV is feasible in canine fetuses, and the presence tDVw seems to be related to neonatal mortality. PMID:27182129

    Introduction Intracavernous alprostadil injection (IAI) is a widely used treatment for sexual rehabilitation (SR) after radical prostatectomy (RP). It is unknown whether the continuation of IAI beyond 1 year continues to improve erectile function. Aims To assess evolution of sexual function in patients using IAI who are nonresponsive to phosphodiesterase type 5 inhibitors (PDE5i) between 12 (M12) and 24 (M24) months after RP. Methods We retrospectively studied 75 men with a nerve-sparing laparoscopic RP, who had normal preoperative erectile function, and who regularly used IAI for SR for at least 24 months. At M12, no patients had responded to PDE5i. Main Outcome Measures At 12 and 24 months, sexual function was assessed with the UCLA Prostate Cancer Index (UCLA-PCI), International Index of Erectile Function (IIEF)-15, and erection hardness score (EHS) with and without IAI. We also assessed the satisfaction rate with IAI, injection-related penile pain, and satisfaction of treatment. Statistical analysis was performed by using t-tests for paired data and Spearman's rho correlation coefficients to assess the relationships between scores at M12 and M24. Results Improvement of nocturnal erection was noted (UCLA-PCI, question 25); however, no significant difference was found for IIEF-erectile function with (19.60 ± 9.80 vs. 18.07 ± 10.44) and without IAI (4.63 ± 2.93 vs. 4.92 ± 4.15), UCLA-PCI-sexual bother (37.14 ± 21.45 vs. 37.54 ± 19.67), nor the EHS score with (2.97 ± 1.30 vs. 2.57 ± 1.30) and without IAI (0.67 ± 1.11 vs. 0.76 ± 0.10). The rate of satisfaction with treatment decreased over time (66.6% vs. 46.7%, P = 0.013). Improved response to IAI at M12 was not correlated to improvement in spontaneous erections at M24. Conclusion The response to IAI remained stable after 2 years of treatment, and no significant improvement of spontaneous erections during intercourse attempts was found between M12 and M24

    Objectives: This study examined trends and socioeconomic and racial/ethnic disparities in cardiovascular disease (CVD) mortality in the United States between 1969 and 2013. Methods: National vital statistics data and the National Longitudinal Mortality Study were used to estimate racial/ethnic and area- and individual-level socioeconomic disparities in CVD mortality over time. Rate ratios and log-linear regression were used to model mortality trends and differentials. Results: Between 1969 and 2013, CVD mortality rates decreased by 2.66% per year for whites and 2.12% for blacks. Racial disparities and socioeconomic gradients in CVD mortality increased substantially during the study period. In 2013, blacks had 30% higher CVD mortality than whites and 113% higher mortality than Asians/Pacific Islanders. Compared to those in the most affluent group, individuals in the most deprived area group had 11% higher CVD mortality in 1969 but 40% higher mortality in 2007-2011. Education, income, and occupation were inversely associated with CVD mortality in both men and women. Men and women with low education and incomes had 46-76% higher CVD mortality risks than their counterparts with high education and income levels. Men in clerical, service, farming, craft, repair, construction, and transport occupations, and manual laborers had 30-58% higher CVD mortality risks than those employed in executive and managerial occupations. Conclusions and Global Health Implications: Socioeconomic and racial disparities in CVD mortality are marked and have increased over time because of faster declines in mortality among the affluent and majority populations. Disparities in CVD mortality may reflect inequalities in the social environment, behavioral risk factors such as smoking, obesity, physical inactivity, disease prevalence, and healthcare access and treatment. With rising prevalence of many chronic disease risk factors, the global burden of cardiovascular diseases is expected to increase

    Background Ischemic heart disease (IHD) mortality has been on the decline in the United States for decades. However, declines in IHD mortality have been slower in certain groups, including young women and black individuals. Hypothesis Trends in IHD vary by age, sex, and race in New York City (NYC). Young female minorities are a vulnerable group that may warrant renewed efforts to reduce IHD. Methods IHD mortality trends were assessed in NYC 1980–2008. NYC Vital Statistics data were obtained for analysis. Age-specific IHD mortality rates and confidence bounds were estimated. Trends in IHD mortality were compared by age and race/ethnicity using linear regression of log-transformed mortality rates. Rates and trends in IHD mortality rates were compared between subgroups defined by age, sex and race/ethnicity. Results The decline in IHD mortality rates slowed in 1999 among individuals aged 35–54 years but not ≥55. IHD mortality rates were higher among young men than women age 35–54, but annual declines in IHD mortality were slower for women. Black women age 35–54 had higher IHD mortality rates and slower declines in IHD mortality than women of other race/ethnicity groups. IHD mortality trends were similar in black and white men age 35–54. Conclusions The decline in IHD mortality rates has slowed in recent years among younger, but not older, individuals in NYC. There was an association between sex and race/ethnicity on IHD mortality rates and trends. Young black women may benefit from targeted medical and public health interventions to reduce IHD mortality.

    Mortality analyses were carried out for 278 male hourly workers who were employed for at least 10 years at a gray iron foundry and who died between January 1, 1970 and December 31, 1981. Statistically significant excess proportional mortality due to non-malignant respiratory disease (SPMR = 177), lung cancer (SPMR = 148), and leukemia (SPMR = 284) was found among the 221 white males. Among nonwhite males there was a significant excess in proportional mortality due to circulatory diseases (SPMR = 143). White males in the Finishing classification experienced a significant excess of proportional mortality due to nonmalignant respiratory disease (SPMR = 279) and lung cancer (SPMR = 179). White males in the Core Room classification experienced an excess of proportional mortality due to nonmalignant respiratory disease (SPMR = 321). Case-control studies demonstrated a significant association between nonmalignant respiratory disease and the Finishing classification after controlling for the effects of age, prior occupations in coal mining or foundries, and smoking. A positive but nonsignificant association between lung cancer and Finishing was also found after controlling for age, prior work history, and smoking in case control studies.

  1. Cancer mortality in merchant seamen.

    Cancer mortality excess has been reported repeatedly over the past hundred years to occur in merchant seamen. More recently lung cancer has been found to account for some of this excess and the question of the contribution made by cigarette smoking raised. In the one study where there was some information on smoking habit, it did not appear that cigarettes would have accounted for all the excess cancer observed. In other mortality studies, where excess cancer mortality was observed, the other cigarette-linked causes of death were not prominent. In a preliminary mortality analysis of a small population of merchant seamen, two cases of malignant mesothelioma have so far been identified, and in a national mesothelioma register 28 cases have been reported in seamen: both instances constitute abnormal occurrences. The presence of substantial amounts of asbestos-containing materials in naval construction which are continuously subjected to vibration and intermittently disturbed during servicing, and the detection of radiological stigmata consistent with asbestos exposure, add plausibility to the hypothesis that occupational asbestos exposure contributes to the apparent excess cancer mortality in merchant seamen. Methodologic deficiencies in epidemiologic studies reported to date make for uncertainty. Properly designed studies will be needed to quantify disease excess and to identify potentially causal associations. Even in the absence of such data it would be prudent to contain the asbestos currently installed and to promote smoking cessation programs.

  2. Mortality patterns in developed countries.

    The implications of recent demographic trends in developed countries are considered. The emphasis is on the increase in life expectancy, and particularly in the rate of growth of the numbers of the very old (those aged 85 and over). "To evaluate the impact of recent mortality reductions on the social security and health service systems of developed countries [the author analyzes] the mortality conditions of 11 developed countries over the period 1950 to 1978." The countries concerned are the United States, Canada, Japan, Norway, Sweden, Denmark, Czechoslovakia, Hungary, the United Kingdom, the Federal Republic of Germany, and France. "The results of [the] analyses show that major increases in life expectancy have occurred at advanced ages for females and that the cross-country differences in the cause of death structure indicate that advances were achieved through a variety of mechanisms. Thus, it appears that no single uniform model of biological aging will currently explain cause specific mortality trends in countries with historically high life expectancies. This implies that further mortality reductions are possible in these countries by achieving cause specific mortality reductions observed to have occurred in another country." This is a revised version of a paper originally presented at the 1983 Annual Meeting of the Population Association of America (see Population Index, Vol. 49, No. 3, Fall 1983, p. 413). PMID:12340261

    The authors sought to determine the prevalence and risk factors for major depressive disorder and posttraumatic stress disorder (PTSD) among survivors living in temporary accommodation in the Yongxing settlement in Mianyang city 1 year after the Sichuan earthquake for further interventions. They interviewed 182 residents, using the Structured Clinical Interview for DSM-IV Axis I Disorders and a self-report questionnaire. The 12-month prevalence of depressive disorder and PTSD were 48.9% and 39.6%, respectively. Multivariate analysis indicated that bereaved survivors were 5.51 times (adjusted odds ratio [AOR] = 5.51; 95% confidence interval [CI] =2.14-14.22) more likely to report PTSD and 2.42 times (AOR = 2.42; 95%CI =1.00-5.48) more likely to report depressive disorder than nonbereaved survivors. Older age and receipt of government financial support were significantly associated with 12-month PTSD. Depressive disorder 12 months after the earthquake was associated with receipt of government financial support, pre-earthquake physical illness, single marital status, being currently employed, and Han ethnicity.

    A healthy 1-year-old boy born at full term after an uncomplicated pregnancy presented to the dermatology clinic for a widespread eruption with gradual onset since 3 months of age. He was otherwise well, afebrile, feeding well, and gaining weight appropriately. The child was overall asymptomatic, though some of his lesions occasionally became red and pruritic. His mother noticed that after mild illnesses, he was more prone to these flares. She denied flushing, vomiting, diarrhea, respiratory distress, and irritability. He was meeting all developmental milestones and started walking at 11 months of age. The remainder of his review of systems was unremarkable, and family history was noncontributory. Physical exam revealed a well-appearing, well-nourished, playful, and interactive toddler. There were innumerable discrete and coalescing pink-brown macules and papules concentrated on the trunk and extending onto the proximal upper and lower extremities bilaterally, as well as the neck and lower face. Stroking the lesions quickly led to development of erythematous edematous wheals. There was no hepatosplenomegaly, and the lymph node exam was unremarkable.

    Continuous monitoring of cardiac rhythm may play an important role in measuring the true symptomatic/asymptomatic atrial fibrillation (AF) burden and improve the management of anti-arrhythmic and anti-thrombotic therapies. Forty-seven patients with mitral valve disease and longstanding persistent AF (LSPAF) underwent a left atrial maze procedure with bipolar radiofrequency and valve surgery. The follow-up data recorded by an implanted loop recorder were analysed after 3, 6 and 12 months. On discharge, 40 (85.1%) patients were in stable sinus rhythm, as documented by in-office electrocardiography (ECG), 4 (8.5%) were in pacemaker rhythm and 3 (6.4%) were in AF. One (2.1%) patient died after 7 months. On 12-month follow-up examination, 30 (65.2%) patients had an AF burden <0.5% and were classified as responders. Three (6.5%) of the 16 non-responders had atrial flutter and 13 (27.7%) had documented AF recurrences with an AF burden >0.5%. Two (4.3%) patients with AF recurrences were completely asymptomatic. Among the symptomatic events stored by the patients, only 27.6% was confirmed as genuine AF recurrences according to the concomitant ECG recorded by the implanted loop recorder. A concomitant bipolar maze procedure during mitral valve surgery is effective in treating AF, as proved by detailed 1-year continuous monitoring. PMID:22514258

    We present results of a 1-year NSF planning grant called Beyond Earth. The project is designed to engage Native American, urban, and rural families in science learning while piloting curriculum development and implementation that incorporates both Native and Western epistemologies. Physical, earth, and space science content is juxtaposed with indigenous culture, stories, language and epistemology in after-school programs and teacher training. Project partners include the Dakota Science Center, Fort Berthold Community College, and Sitting Bull College. The Native American tribes represented in this initiative illustrate partnerships between the Dakota, Lakota, Nakota, Hidatsa, Mandan, and Arikara. Over the past year the primary project deliverables include a culturally responsive curriculum Beyond Earth Moon Module, teacher training workshops, a project website. The curriculum module introduces students to the moon's appearance, phases, and positions in the sky using the Night Sky Planetarium Experience Station to explore core concepts underlying moon phases and eclipses using the interactive Nature Experience Station before engaging in the culminating Mission Challenge in which they apply their knowledge to problem solving situations and projects. The Native Science and Western Science activities developed, planetarium explorations created, and website toolkit utilizations are presented.

    It is widely accepted that a redundant independent dose calculation (RIDC) must be included in any treatment planning verification procedure. Specifically, volumetric modulated arc therapy (VMAT) technique implies a comprehensive quality assurance (QA) program in which RIDC should be included. In this paper, the results obtained in 1 year of clinical experience are presented. Eclipse from Varian is the treatment planning system (TPS), here in use. RIDC were performed with the commercial software; Diamond® (PTW) which is capable of calculating VMAT fields. Once the plan is clinically accepted, it is exported via Digital Imaging and Communications in Medicine (DICOM) to RIDC, together with the body contour, and then a point dose calculation is performed, usually at the isocenter. A total of 459 plans were evaluated. The total average deviation was -0.3 ± 1.8% (one standard deviation (1SD)). For higher clearance the plans were grouped by location in: Prostate, pelvis, abdomen, chest, head and neck, brain, stereotactic radiosurgery, lung stereotactic body radiation therapy, and miscellaneous. The highest absolute deviation was -0.8 ± 1.5% corresponding to the prostate. A linear fit between doses calculated by RIDC and by TPS produced a correlation coefficient of 0.9991 and a slope of 1.0023. These results are very close to those obtained in the validation process. This agreement led us to consider this RIDC software as a valuable tool for QA in VMAT plans. PMID:25525309

  8. Attenuated hypothalamic-pituitary-adrenal axis functioning predicts accelerated pubertal development in girls 1 year later.

    Accelerated pubertal development has been linked to adverse early environments and may heighten subsequent mental and physical health risks. Hypothalamic-pituitary-adrenal axis functioning has been posited as a mechanism whereby stress may affect pubertal development, but the literature lacks prospective tests of this mechanism. The current study assessed 277 youth (M = 10.84 years, SD = 1.14), 138 boys and 139 girls, who reported on their pubertal development and underwent the Trier Social Stress Test for Children at baseline and returned to the laboratory approximately 1 year later (M = 1.12 years, range = 0.59-1.98 years). For girls, lower cortisol area under the curve (with respect to ground) at Time 1 predicted more advanced pubertal development at Time 2, controlling for Time 1 pubertal development. This association persisted after additional covariates including age, body mass index, race, and maltreatment history were introduced, and was driven by adrenal rather than gonadal development. Cortisol was not linked to boys' subsequent pubertal development, and no interaction by gender or by maltreatment appeared. These results suggest that attenuated cortisol, reported in other studies of children exposed to early adversity, may contribute to accelerated pubertal tempo in girls.

    Two 1-year studies evaluated the long-term efficacy and safety of tiotropium 5 or 10 microg versus placebo, inhaled via the Respimat Soft Mist Inhaler (SMI). The two studies were combined and had 4 co-primary endpoints (trough FEV(1) response, Mahler Transition Dyspnea Index [TDI] and St George's Respiratory Questionnaire scores all at week 48, and COPD exacerbations per patient-year). A total of 1990 patients with COPD participated (mean FEV(1): 1.09 L). The mean trough FEV(1) response of tiotropium 5 or 10 microg relative to placebo was 127 or 150 mL, respectively (both P < 0.0001). The COPD exacerbation rate was significantly lower with tiotropium 5 microg (RR = 0.78; P = 0.002) and tiotropium 10 microg (RR = 0.73; P = 0.0008); the health-related quality of life and Mahler TDI co-primary endpoints were significantly improved with both doses (both P < 0.0001). Adverse events were generally balanced except anticholinergic class effects, which were more frequent with active treatment. Fatal events occurred in 2.4% (5 microg), 2.7% (10 microg), and 1.6% (placebo) of patients; these differences were not significant. Tiotropium Respimat SMI 5 microg demonstrated sustained improvements in patients with COPD relative to placebo and similar to the 10 microg dose but with a lower frequency of anticholinergic adverse events.

    The present study was carried out to provide information about outcome of the Jetstream atherectomy device for treatment of infrainguinal arteries. From February 2006 to February 2007, 172 patients with Rutherford class 1 to 5 lower limb ischemia were enrolled at 9 study sites. The endpoints were evaluation of quality of life according to the walking impairment questionnaire (WIQ) besides technical parameters. In the total study cohort, the WIQ scale maintained improved up to 12-month follow-up. Furthermore, target lesion revascularization rate was 26% (42/162), ankle-brachial index (ABI) increased from 0.59 ± 0.21 at baseline to 0.82 ± 0.27 (P < 0.05), and mean Rutherford class dropped from 3.0 ± 0.9 at baseline to 1.5 ± 1.3 at 1 year (P < .05). The results of this prospective, multicenter, clinical study demonstrate that the Jetstream atherectomy device is a potential treatment alternative for the endovascular management to improve clinical outcome in patients with peripheral arterial occlusive disease.

    In 2003, the program "The combined DAK therapy of obesity for children and adolescents", funded and conducted by the Deutsche Angestellten Krankenkasse (DAK) (A German Health Insurance Company), has started. The whole treatment lasts for 1 year including an initial inpatient therapy for 6 weeks followed by an outpatient treatment at home that adresses the overweight patients and their families. The therapy contents are developed according to the recommendations of the "Arbeitsgemeinschaft Adipositas im Kindes- und Jugendalter (AGA)". In a prospective cohort study a sample of 604 subjects was studied in order to examine the achievement of the treatment goals weight reduction, behaviour modification and improvement of quality of life. The development of weight was evaluated using BMI-SDS. 44,1% of children and adolescents had a successful weight reduction, they reduced their weight at least by 0,3 BMI-SDS. Furthermore, significant changes of health behaviour, physical fitness and quality of life were observed. However, during the outpatient treatment an impairment of some behaviour changes were observed. Nevertheless, the study has identified significant, positive effects in weight loss, behaviour modifications, changes in physical fitness and in the development of quality of life as a result of the therapy. It is demonstrated that a relapse in "old behaviour" followed by an increase of weight after the inpatient treatment can be avoided bythe subsequent outpatient therapy.

    Adrenal insufficiency is a rare but life-threatening disease. Replacement therapy sometimes fails to prevent an acute adrenal crisis and most often does not lead to restoration of well-being. We report here the 1-year outcome of the first simultaneous kidney-adrenal gland-pancreas transplantation in a 33-year-old patient with type 1 diabetes and concomitant autoimmune adrenal insufficiency. En bloc left adrenal gland and kidney grafts were anastomosed on the left iliac vessels in normal vascular conditions and the pancreas graft was anastomosed on the right iliac vessels. The immunosuppressive regimen was not modified by the addition of the adrenal gland. We observed no additional morbidity due to the adrenal gland transplantation, as there were no surgical complications. One-year kidney and pancreas graft functions were satisfactory (estimated glomerular filtration rate: 55 mL/min/1.73 m(2) and HbA1c: 4.8%). The adrenal graft functioned well at 12 months with a normalization of cortisol and aldosterone baseline levels. Functional imaging at 3 months showed good uptake of [(123) I]-metaiodobenzylguanidine by the adrenal graft. Transplantation of the adrenal gland en bloc with the left kidney appears to be a good therapeutic option in patients with adrenal insufficiency awaiting kidney or kidney-pancreas transplantation.

    Research findings are inconsistent about improvement of specific cardio-metabolic variables after lifestyle intervention in obese children. The aim of this trial was to evaluate the effect of a 1-year intervention, based on normocaloric diet and physical activity, on body mass index (BMI), blood lipid profile, glucose metabolism and metabolic syndrome. Eighty-five obese children aged ≥6 years were analyzed. The BMI z-score was calculated. Fasting blood samples were analyzed for lipids, insulin and glucose. The homeostatic model assessment of insulin resistance (HOMA-IR) was calculated and insulin resistance was defined as HOMA-IR >3.16. HOMA-β%, quantitative insulin sensitivity check index and triglyceride glucose index were calculated. The metabolic syndrome was defined in accordance with the International Diabetes Federation criteria. At the end of intervention children showed a reduction (mean (95% CI)) in BMI z-score (-0.58 (-0.66; -0.50)), triglycerides (-0.35 (-0.45; -0.25) mmol/L) and triglyceride glucose index (-0.29 (-0.37; -0.21)), and an increase in HDL cholesterol (0.06 (0.01; 0.11) mmol/L). Prevalence of insulin resistance declined from 51.8% to 36.5% and prevalence of metabolic syndrome from 17.1% to 4.9%. Nutritional-behavioral interventions can improve the blood lipid profile and insulin sensitivity in obese children, and possibly provide benefits in terms of metabolic syndrome.

    Iodine is the main constituent of thyroid hormones, which in turn are required for fetal brain development. However, the relation between iodine intake during pregnancy, thyroid function, and child neurodevelopment needs further evaluation. The authors assessed the association of maternal iodine intake from diet and supplements during pregnancy and of maternal and neonatal thyroid function with infant neurodevelopment. The Mental Development Index and Psychomotor Development Index (PDI) for 691 children were obtained between 2005 and 2007 using the Bayley Scales of Infant Development at age 1 year in a prebirth cohort in Valencia, Spain. In multivariate analyses, a maternal thyrotropin level >4 μU/mL was associated with an increased risk of a PDI <85 (odds ratio = 3.5, P = 0.02). Maternal intake of ≥150 μg/day, compared with <100 μg/day, of iodine from supplements was associated with a 5.2-point decrease in PDI (95% confidence interval: -8.1, -2.2) and a 1.8-fold increase in the odds of a PDI <85 (95% confidence interval: 1.0, 3.3). When analyses were stratified by sex, this association was intensified for girls but was not observed for boys. Further evidence on the safety and effectiveness of iodine supplementation during pregnancy is needed before it is systematically recommended in iodine-sufficient or mildly deficient areas.

    A 1-year-old female Labrador retriever was referred with a few days history of haematic-like vulvar discharge. Physical examination, vaginal inspection and palpation did not reveal any remarkable finding. Transabdominal ultrasound showed echogenic fluid accumulation in the vagina suggesting haemato-pyocolpos. An exploratory laparotomy was performed: a well-delimited ectasic vagina was identified. Ovariohysterectomy and partial vaginectomy and vaginoplasty were performed to spay the bitch and to remove the ectasic vagina. Post-operative recovery and 12-month follow-up were uneventful. Clinical, morphological and histological findings were consistent with a congenital abnormality of the muscular layer of the vagina complicated by haemato-pyocolpos. The disorganization of the vaginal tunica muscularis may have acted as locus minoris resistentiae in the vaginal wall. The organ was dilated and atonic due to the gradual accumulation of physiological fluids complicated by an overgrowth of genital bacteria. This congenital disorder has to be taken into account as differential diagnosis of haemato-pyocolpos with vaginal discharge in young bitches.

    Static two-point discrimination, pressure, and vibratory threshold values were measured at standard coordinates in the area corresponding to the infraorbital nerve distribution in 59 adolescents 1 year after undergoing LeFort I osteotomy. The patients were divided into three groups: those born with unilateral cleft lip and palate (n = 30; mean age, 18 years; SD = 2); those with bilateral cleft lip and palate (n = 12; mean age, 19 years; SD = 3); and those without a cleft (n = 17; mean age, 19 years; SD = 3). One year after the osteotomy, none of the patients complained of altered sensibility in the maxillary vestibular mucosa, gingiva, or upper lip and cheek regions. No significant differences were found between the mean postoperative sensibility values of patients with and without clefts, indicating that the presence of clefting did not affect sensory recovery. Mean postoperative static two-point discrimination values were higher than preoperative values in all areas tested and in all patient groups. These results suggest that the sensory recovery, although incomplete, was strong enough to mask any subjective feelings of changes in sensory function.

    We sampled the surface waters (2-50 m) of two deep peri-alpine lakes over a 1-year period in order to examine (1) the abundance, vertical distribution, genome size, and morphology structures of the virioplankton; (2) the virus-mediated bacterial mortality; and (3) the specific genome size range of double-stranded DNA (dsDNA) phytoplankton viruses. Virus-like particle (VLP) concentrations varied between 4.16 × 10(7) (January) and 2.08 × 10(8) part mL(-1) (May) in Lake Bourget and between 2.7 × 10(7) (June) and 8.39 × 10(7) part mL(-1) (November) in Lake Annecy. Our flow cytometry analysis revealed at least three viral groups (referred to as virus-like particles 1, 2, and 3) that exhibited distinctive dynamics suggestive of different host types. Phage-induced bacterial mortality varied between 6.1% (June) and 33.2% (October) in Lake Bourget and between 7.4% (June) and 52.6% (November) in Lake Annecy, suggesting that viral lysis may be a key cause of mortality of the bacterioplankton. Virioplankton genome size ranged from 27 to 486 kb in Lake Bourget, while it reached 620 kb in Lake Annecy for which larger genome sizes were recorded. Our analysis of pulsed field gel electrophoresis bands using different PCR primers targeting both cyanophages and algal viruses showed that (1) dsDNA viruses infecting phytoplankton may range from 65 to 486 kb, and (2) both cyanophage and algal "diversity" were higher in Lake Annecy. Lakes Annecy and Bourget also differed regarding the proportions of both viral families (with the dominance of myoviruses vs. podoviruses) and infected bacterial morphotypes (short rods vs. elongated rods), in each of these lakes, respectively. Overall, our results reveal that (1) viruses displayed distinct temporal and vertical distribution, dynamics, community structure in terms of genome size and morphology, and viral activity in the two lakes; (2) the Myoviridae seemed to be the main cause of bacterial mortality in both lakes and this

The pre-operative K-SES(Future) was furthermore a significant predictor of an acceptable outcome 1 year after surgery, on the Lysholm knee scoring scale (P = 0.003, odds ratio = 1.7), as well as on KOOS(Sports/recreation) (P = 0.002, odds ratio = 1.6) and knee-related quality of life (KOOS(Qol)) (P = 0.037, odds ratio = 1.4), when adjusted for age, gender and Tegner(Pre-injury). The pre-operative K-SES(Future) was also a significant predictor (P = 0.04) of an acceptable outcome 1 year after surgery, on the one-leg hop for distance (odds ratio = 2.2), when adjusted for age, gender and Tegner(Pre-injury). In conclusion, this study indicates that patients' perceived self-efficacy of knee function pre-operatively is of predictive value for their return to acceptable levels of physical activity, symptoms and muscle function 1 year after ACL reconstruction.

    Objectives To derive a model of paediatric postdischarge mortality following acute infectious illness. Design Prospective cohort study. Setting 2 hospitals in South-western Uganda. Participants 1307 children of 6 months to 5 years of age were admitted with a proven or suspected infection. 1242 children were discharged alive and followed up 6 months following discharge. The 6-month follow-up rate was 98.3%. Interventions None. Primary and secondary outcome measures The primary outcome was postdischarge mortality within 6 months following the initial hospital discharge. Results 64 children died during admission (5.0%) and 61 died within 6 months of discharge (4.9%). Of those who died following discharge, 31 (51%) occurred within the first 30 days. The final adjusted model for the prediction of postdischarge mortality included the variables mid-upper arm circumference (OR 0.95, 95% CI 0.94 to 0.97, per 1 mm increase), time since last hospitalisation (OR 0.76, 95% CI 0.61 to 0.93, for each increased period of no hospitalisation), oxygen saturation (OR 0.96, 95% CI 0.93 to 0·99, per 1% increase), abnormal Blantyre Coma Scale score (OR 2.39, 95% CI 1·18 to 4.83), and HIV-positive status (OR 2.98, 95% CI 1.36 to 6.53). This model produced a receiver operating characteristic curve with an area under the curve of 0.82. With sensitivity of 80%, our model had a specificity of 66%. Approximately 35% of children would be identified as high risk (11.1% mortality risk) and the remaining would be classified as low risk (1.4% mortality risk), in a similar cohort. Conclusions Mortality following discharge is a poorly recognised contributor to child mortality. Identification of at-risk children is critical in developing postdischarge interventions. A simple prediction tool that uses 5 easily collected variables can be used to identify children at high risk of death after discharge. Improved discharge planning and care could be provided for high-risk children. PMID

    We studied the mortality experience of all pilots who died in the province of British Columbia between 1950 and 1984, using proportional mortality ratios (PMR) and proportional cancer mortality ratios (PCMR). There were 341 deaths during that time in males whose usual occupation was listed as pilot. The PMR for aircraft accidents was significantly elevated (PMR = 3196, 95% C.I. 2810, 3634), and the PMR for atherosclerotic heart disease was significantly depressed (PMR = 47, 95% C.I. 30, 70). Although based on small numbers of deaths, and not statistically significant, elevated PCMRs were seen for cancers of the colon, brain, and nervous system, as well as for Hodgkin's disease. These findings suggest the need for further epidemiologic studies of commercial airline pilots. PMID:2031640

    Cardiovascular diseases are the main causes of mortality. Sudden cardiac death may also appear in athletes, due to underlying congenital or inherited cardiac abnormalities. The electrocardiogram is used in clinical practice and clinical trials, as a valid, reliable, accessible, inexpensive method. The aim of the present paper was to review electrocardiographic (ECG) signs associated with cardiovascular mortality and the mechanisms underlying those associations, providing a brief description of the main studies in this area, and consider their implication for clinical practice in the general population and athletes. The main ECG parameters associated with cardiovascular mortality in the present paper are the P wave (duration, interatrial block, and deep terminal negativity of the P wave in V1), prolonged QT and Tpeak-Tend intervals, QRS duration and fragmentation, bundle branch block, ST segment depression and elevation, T waves (inverted, T wave axes), spatial angles between QRS and T vectors, premature ventricular contractions, and ECG hypertrophy criteria.

    A cohort mortality study was carried out in Vermont granite workers who had been employed between the years 1950 and 1982. The cohort included men who had been exposed to high levels of granite dust prior to 1938-1940 (average cutters to 40 million parts/cubic foot), and those employed at dust levels after 1940, which on average were less than 10 million parts/cubic foot. Deaths were coded by a qualified nosologist and standardized mortality ratios were calculated. The results confirm previous studies that show that death rates from silicosis and tuberculosis, the major health threats in the years before 1940, were essentially eliminated after dust controls. However, we found excessive mortality rates from lung cancer in stone shed workers who had been employed prior to 1930, and hence had been exposed to high levels of granite dust. When information was available, 100% of those dying from lung cancer had been smokers.

  4. Pharmacotherapy to reduce arrhythmic mortality

    Fatal ventricular arrhythmias and heart failure are the common modes of death in patients with cardiovascular diseases. Intracardiac defibrillator (ICD) implantation reduces arrhythmic mortality to a significant extent in the high risk patient. However, there continues to be a need for effective drug therapy to reduce the arrhythmic and overall mortality in patients with or without an ICD. Although anti-arrhythmic drugs (AAD) appear inferior to ICD, the role of beta-blockers and to an extent amiodarone along with non AAD like angiotensin converting enzyme inhibitors (ACE-I), mineralocorticoid blockers (MRB) and HMG-CoA reductase inhibitors (statins) need to be emphasized. There have been many drug trials and meta-analysis to this effect and we review the role of drugs especially in their ability to reduce arrhythmic mortality and sudden cardiac death (SCD). The focus is on post myocardial infarction (MI) and heart failure patients with a brief overview of role of drugs in channelopathies. PMID:24568822

    Vascular markers such as pulse-wave velocity and carotid intima-media thickness (CIMT) might improve the prediction of incident cardiovascular disease beyond traditional risk factors. These vascular markers have not been well characterized in minority populations and might be more useful than inflammatory biomarkers. We conducted a prospective, longitudinal cohort study among hypertensive patients in an urban safety-net hospital. We evaluated inflammatory biomarkers, arterial pulse-wave velocity, and carotid intima-media thickness at baseline, 1 year, and 2 years. The primary outcome variable was CIMT. Generalized linear mixed-effects models were used to evaluate associations between CIMT and predictive variables accounting for the correlation of multiple measurements within subjects over time. For our secondary outcome, we used administrative and National Death Index data to determine all-cause death, and univariate relationships were evaluated. Among 175 subjects, 117 were Latino (67%) and 117 were female (67%). Pulse-wave velocity and CIMT regressed over time (both P <0.001) and were highly correlated (P <0.001). Only pulse-wave velocity (P=0.002) and total cholesterol (P=0.03) were associated with CIMT in time-varying covariate analysis. At a median follow-up period of 80 months, 17 of 175 subjects had died (10%). Higher baseline CIMT and pulse-wave velocity were associated with increased mortality rates (both P <0.01). No serum inflammatory marker was significantly correlated with longitudinal changes in CIMT or death. In conclusion, both arterial stiffness and preclinical carotid atherosclerosis were associated with increased mortality rates and might be useful risk-stratification markers among this minority population.

    Background 30-40% of cardiac resynchronization therapy cases do not achieve favorable outcomes. Objective This study aimed to develop predictive models for the combined endpoint of cardiac death and transplantation (Tx) at different stages of cardiac resynchronization therapy (CRT). Methods Prospective observational study of 116 patients aged 64.8 ± 11.1 years, 68.1% of whom had functional class (FC) III and 31.9% had ambulatory class IV. Clinical, electrocardiographic and echocardiographic variables were assessed by using Cox regression and Kaplan-Meier curves. Results The cardiac mortality/Tx rate was 16.3% during the follow-up period of 34.0 ± 17.9 months. Prior to implantation, right ventricular dysfunction (RVD), ejection fraction < 25% and use of high doses of diuretics (HDD) increased the risk of cardiac death and Tx by 3.9-, 4.8-, and 5.9-fold, respectively. In the first year after CRT, RVD, HDD and hospitalization due to congestive heart failure increased the risk of death at hazard ratios of 3.5, 5.3, and 12.5, respectively. In the second year after CRT, RVD and FC III/IV were significant risk factors of mortality in the multivariate Cox model. The accuracy rates of the models were 84.6% at preimplantation, 93% in the first year after CRT, and 90.5% in the second year after CRT. The models were validated by bootstrapping. Conclusion We developed predictive models of cardiac death and Tx at different stages of CRT based on the analysis of simple and easily obtainable clinical and echocardiographic variables. The models showed good accuracy and adjustment, were validated internally, and are useful in the selection, monitoring and counseling of patients indicated for CRT. PMID:26559987

    Aim: Oral risedronate is effective in the treatment of postmenopausal osteoporosis when administered daily, weekly, or monthly. In this 1-year, randomized, double-blind, multicenter study we compared the weekly 35-mg and daily 5-mg risedronate dosing regimens in the treatment of Chinese postmenopausal women with osteoporosis or osteopenia. Methods: Postmenopausal women with primary osteoporosis or osteopenia were randomly assigned to the weekly group or daily group (n=145 for each) that received oral risedronate 35 mg once a week or 5 mg daily, respectively, for 1 year. The subjects' bone mineral densities (BMDs), bone turnover markers (P1NP and β-CTX), new vertebral fractures, and adverse events were assessed at baseline and during the treatments. Results: All subjects in the weekly group and 144 subjects in the daily group completed the study. The primary efficacy endpoint after 1 year, ie the mean percent changes in the lumbar spine BMD (95% CI) were 4.87% (3.92% to 5.81%) for the weekly group and 4.35% (3.31% to 5.39%) for the daily group. The incidences of clinical adverse events were 48.3% in the weekly group and 54.2% in the daily group. Conclusion: The weekly 35-mg and daily 5-mg risedronate dosing regimens during 1 year of follow-up show similar efficacy in improving BMDs and biochemical markers of bone turnover in Chinese postmenopausal women with osteoporosis or osteopenia. Moreover, the two dosing regimens exhibit similar safety and tolerability. PMID:26051110

    Aim: To assess the changes in corneal hysteresis (CH) and corneal resistance factor (CRF) 1-year following transepithelial corneal collagen cross-linking (CXL) treatment in eyes of children with keratoconus. Methods: This case series was conducted in 22 eyes of 22 children. Children aged < 18 years with progressive keratoconus were included. They were treated with transepithelial CXL. Corneal biomechanical and anterior chamber parameters such as CH, CRF, and peak 1 were noted using ocular response analyzer, Pentacam, intraocular lens master, and anterior segment optical coherence tomography before and 1, 3, 6, and 12 months after treatment. Results: Our series had 22 eyes of 22 children with a mean age 15.7 ± 2.1 years. The CH and CRF 1-year after treatment declined (difference of mean 0.1 mmHg (95% confidence interval [CI] 0.04–0.24), P = 0.2] and (difference of mean 0.1 mmHg [95% CI 0.04–0.30], P = 0.3), respectively. Peak 1 and peak 2 increased (difference of mean 0.1 mmHg [95% CI 0.006–0.008], P = 0.2) and (difference of mean 0.1 mmHg [95% CI 0.007–0.006], P = 0.3), respectively. The uncorrected distance visual acuity improved from 0.95 ± 0.34 logMAR to 0.68 ± 0.45 logMAR (P < 0.05). No statistically significant changes during 12 months follow-up were observed in axial length, corneal volume, anterior chamber volume, and anterior chamber depth (P > 0.05). Conclusion: Transepithelial CXL in keratoconus in pediatric age group seems to have good stability in corneal biomechanical parameters after 1-year. Further studies with a larger sample and better study design are recommended to confirm our findings. PMID:26957852

    Associations of race, smoking history and fibrinogen levels with cancer mortality were investigated prospectively using the ARIC study. Our cohort consisted of 14,320 participants aged 45-64 at baseline. In an adjusted Cox regression, black current heavy smokers (> or = 15 cigarettes per day) demonstrated higher risk of respiratory/intrathoracic organ cancer mortality than nonblack current heavy smokers. Black former heavy smokers were also found to be at an increased risk of respiratory/intrathoracic organ cancer mortality when compared to nonblack former heavy smokers. Elevated fibrinogen levels were associated with an increased risk of respiratory/intrathoracic organ cancer mortality. Compared to fibrinogen < 259 mg/dl, fibrinogen 294-335 mg/dl had an adjusted hazard ratio of 3.68 (95% CI: 1.80-7.55), and fibrinogen > or = 336 mg/dl had an adjusted hazard ratio of 3.78 (95% CI: 1.84-7.75). Fibrinogen was also a predictor of other types of cancer mortality among black participants, but not among nonblack participants. For 10 race/smoking history categories, fibrinogen levels ranged from a mean of 287 mg/dl for nonblack former light smokers to a mean of 338 mg/dl for black current heavy smokers. Smokers had higher fibrinogen levels than nonsmokers, and black smokers had higher fibrinogen levels than nonblack smokers. Smoking carries high risks of cancer mortality for African Americans. A factor that needs to be considered in the overall assessment of risk is fibrinogen level, which has been linked to angiogenesis and metastases of tumors. PMID:17444421

    AIM: To analyze the effect of age-period and birth cohort on gastric cancer mortality, in Brazil and across its five geographic regions, by sex, in the population over 20 years of age, as well as make projections for the period 2010-2029. METHODS: An ecological study is presented herein, which distributed gastric cancer-related deaths in Brazil and its geographic regions. The effects of age-period and birth cohort were calculated by the Poisson regression model and projections were made with the age-period-cohort model in the statistical program R. RESULTS: Progressive reduction of mortality rates was observed in the 1980’s, and then higher and lower mortality rates were verified in the 2000’s, for both sexes, in Brazil and for the South, Southeast and Midwest regions. A progressive decrease in mortality rates was observed for the Northeast (both sexes) and North (men only) regions within the period 1995-1999, followed by rising rates. CONCLUSION: Regional differences were demonstrated in the mortality rates for gastric cancer in Brazil, and the least developed regions of the country will present increases in projected mortality rates.

    The objective of this paper is to investigate mortality among 1247 male asbestos-cement workers employed in an asbestos-cement plant located in Naples. The cohort included 1247 men hired between 1950 and 1986. The follow-up began on January 1st 1965. The vital status and causes of death were ascertained up to December 31 2005. Cause-specific mortality rates of the Campania Region population were used as reference. Relative risks were estimated using Standardized Mortality Ratios (SMRs), and the confidence intervals were calculated at a 95% level (95% CI). A significant increase in mortality was observed for respiratory disease (81 deaths; SMR = 187; 95% CI = 149- 233), particularly for pneumoconiosis (42 deaths; SMR = 13 313; 95% CI = 9595-17 996) of which 41 deaths for asbestosis (SMR = 43 385; 95% CI = 31 134-58 857), for pleural cancer (24 deaths; SMR = 2617; 95% CI = 1677-3893), for lung cancer (84 deaths; SMR=153; 95% CI = 122-189) and for peritoneal cancer (9 deaths; SMR = 1985; 95% CI = 908-3769). Non-significant increases were also observed for rectum cancer (6 deaths; SMR = 157; 95% CI = 58-342). In conclusion, consistently with other mortality studies on asbestos-cement workers performed in different countries, an increased mortality from asbestosis, lung cancer, pleural and peritoneal mesothelioma was detected in the present cohort.

    Background Cystic hydatid disease is still an important health problem in European Mediterranean areas. In spite of being traditionally considered as a “benign” pathology, cystic echinococcosis is an important cause of morbidity in these areas. Nevertheless, there are few analyses of mortality attributed to human hydatidosis. Objective To describe the epidemiology, the mortality rate and the causes of mortality due to E. granulosus infection in an endemic area. Methodology A retrospective study followed up over a period of 14 years (1998–2011). Principal Findings Of the 567 patients diagnosed with hydatid disease over the period 1998–2011, eleven deaths directly related to hydatid disease complications were recorded. Ten patients (90.9%) died due to infectious complications and the remaining one (9.1%) died due to mechanical complications after a massive hemoptysis. We registered a case fatality rate of 1.94% and a mortality rate of 3.1 per 100.000 inhabitants. Conclusions Hydatidosis is still a frequent parasitic disease that causes a considerable mortality. The main causes of mortality in patients with hydatidosis are complications related to the rupture of CE cysts with supurative collangitis. Therefore, an expectant management can be dangerous and it must be only employed in well-selected patients. PMID:24632824

    2013-01-01

    Alcohol abuse has numerous adverse health and social consequences. The consumer response to changes in alcohol affordability is an important issue on alcohol policy debates. Studies from many countries have shown an inverse relationship between alcohol prices and alcohol consumption in the population. There are, however, suggestions that increasing the price of alcohol by rising taxes may have limited effect on alcohol-related problems, associated with long-term heavy drinking. The aim of the present study was to evaluate the relationship between alcohol affordability and alcohol-related mortality rates in post-Soviet Belarus. For this purpose trends in alcohol-related mortality rates (mortality from liver cirrhosis, pancreatitis, alcoholism and alcohol psychoses) and affordability of vodka between 1990 and 2010 were compared. The time series analysis revealed that 1% increase in vodka affordability is associated with an increase in liver cirrhosis mortality of 0,77%, an increase in pancreatitis mortality of 0.53%, an increase in mortality from alcoholism and alcohol psychoses of 0,70%. The major conclusion emerging from this study is that affordability of alcohol is one of the most important predictor of alcohol-related problems in a population. These findings provide additional evidence that decreasing in affordability of alcohol is an effective strategy for reducing alcohol consumption and alcohol-related harm.

    Observational studies involving hemodialysis patients suggest a U-shaped relationship between BP and mortality, but the majority of these studies followed large, heterogeneous cohorts. To examine whether age, race, and diabetes status affect the association between systolic BP (SBP; predialysis) and mortality, we studied a cohort of 16,283 incident hemodialysis patients. We constructed a series of multivariate proportional hazards models, adding age and BP to the analyses as cubic polynomial splines to model potential nonlinear relationships with mortality. Overall, low SBP associated with increased mortality, and the association was more pronounced among older patients and those with diabetes. Higher SBP associated with increased mortality among younger patients, regardless of race or diabetes status. We observed a survival advantage for black patients primarily among older patients. Diabetes associated with increased mortality mainly among older patients with low BP. In conclusion, the design of randomized clinical trials to identify optimal BP targets for patients with ESRD should take age and diabetes status into consideration.

    Purpose: Our objective was to determine the risk factors for inpatient mortality of pediatric patients diagnosed with lymphoma through the utilization of a large national pediatric database. Methods: This cross-sectional study uses data from the Healthcare Cost and Utilization Project Kids' Inpatient Database (HCUP KID) for the year of 2012 to estimate the risk factors for inpatient mortality for pediatric patients diagnosed with lymphoma. All patients diagnosed with lymphoma between the ages of one and 18 years were included. Chi-square test was used to analyze categorical variables. Independent t-test was used to analyze continuous variables. Results: A total of 2,908 study subjects with lymphoma were analyzed. Of those, 56.1% were male and the average age was three years old. Total inpatient mortality was 1.2% or 34 patients. We found that patients with four or more chronic conditions were much more likely to die while hospitalized (p < 0.0001). In addition, we also saw that patients with median household incomes below $47,999 dollars (p = 0.05) having a need for a major procedure (p = 0.008) were associated with inpatient mortality. Congestive heart failure, renal failure, coagulopathy, metastatic disease, and electrolyte abnormalities were all found to be associated with inpatient mortality. Conclusions: Pediatric lymphoma mortality in children is not only influenced by their medical condition but also by their socioeconomic condition as well. PMID:27433403

    Perceived stress is associated with poor health outcomes including negative affect, increased susceptibility to the common cold and cardiovascular disease; the consequences of perceived stress for mortality, however, have received less attention. This study characterizes the relationship between perceived stress and 11-year mortality in a population of Taiwanese adults aged 53+ years. Using the Survey of Health and Living Status of the Near Elderly and Elderly of Taiwan, we calculated a composite measure of perceived stress based on six items pertaining to the health, financial situation, and occupation of the respondents and their families. Proportional hazard models were used to determine whether perceived stress predicted mortality. After adjusting for sociodemographic factors only, we found that a one standard deviation increase in perceived stress was associated with a 19% increase in all-cause mortality risk during the 11-year follow-up period (hazard ratio, HR = 1.19, 95% confidence interval, CI 1.13-1.26). The relationship was greatly attenuated when perceptions of stress regarding health were excluded, and was not significant after adjusting for medical conditions, mobility limitations and depressive symptoms. We conclude that the association between perceived stress and mortality is explained by an individual's current health; however, our data do not allow us to distinguish between two possible interpretations of this conclusion: (a) the relationship between perceived stress and mortality is spurious, or (b) poor health acts as the mediator.

    Background and Objective: Sepsis remains a leading cause of death across the world, carrying a mortality rate of 20–50%. Women have been reported to be less likely to suffer from sepsis and to have a lower risk of mortality from sepsis compared to men. The objective of this study was to determine the relationship between gender and mortality in sepsis, and compare cytokine profiles of male and female patients. Methods: This was a prospective case series on 97 patients admitted with sepsis. Clinical and microbiological data was gathered, blood samples were collected for cytokine (IL-10, IL-6 and TNFα) levels and patients were followed up for clinical outcome. Results: There were 54% males and 46% females, with no significant difference of age or comorbids between genders. Respiratory tract infection was the commonest source of sepsis, and was more common in females (60%) compared to males (39%) (p=0.034). Males had a higher mortality (p=0.048, RR 1.73) and plasma IL-6 level(p=0.040) compared to females. Mean IL-6 plasma level was significantly (p<0.01) higher in patients who died vs. who recovered. Conclusion: Our study shows that males with sepsis have a 70% greater mortality rate, and mortality is associated with a higher IL-6 plasma level. PMID:26649014

    Objective The aim of the study was the evaluation of patients treated with a diagnosis of gastroschisis and to establish the factors which affected the morbidity and mortality. Methods Twenty-nine patients, managed for gastroschisis during 2000-2010 were reviewed retrospectively. Patients were analysed in respect to gestational age, birth weight, associated anomalies, type of delivery, operative procedures, postoperative complications, total parenteral nutrition (TPN) related complications. The factors affecting mortality and morbidity were determined. Findings Associated abnormalities were present in 24% of the patients. Eleven patients underwent elective reduction in the incubator (Bianchi procedure) without anesthesia. Eight patients had delayed reduction with silo and ten patients had primary closure. Although the type of delivery had an effect on morbidity but not mortality, gestational age, birth weight, and the operative procedure performed had no effect on morbidity or mortality. Duration until tolerance of oral intake, and of TPN and hospitalization were found to be statistically significantly shorter in the group of babies delivered by cesarean section. Conclusion In our study the most important cause of mortality was the abdominal compartment syndrome and multi-organ failure in the early years. Long hospitalization periods and sepsis were the main causes of mortality in recent years. PMID:23399980

  1. Does reservoir host mortality enhance transmission of West Nile virus?

    Background Since its 1999 emergence in New York City, West Nile virus (WNV) has become the most important and widespread cause of mosquito-transmitted disease in North America. Its sweeping spread from the Atlantic to the Pacific coast was accompanied by widespread mortality among wild birds, especially corvids. Only sporadic avian mortality had previously been associated with this infection in the Old World. Here, we examine the possibility that reservoir host mortality may intensify transmission, both by concentrating vector mosquitoes on remaining hosts and by preventing the accumulation of "herd immunity". Results Inspection of the Ross-Macdonald expression of the basic reproductive number (R0) suggests that this quantity may increase with reservoir host mortality. Computer simulation confirms this finding and indicates that the level of virulence is positively associated with the numbers of infectious mosquitoes by the end of the epizootic. The presence of reservoir incompetent hosts in even moderate numbers largely eliminated the transmission-enhancing effect of host mortality. Local host die-off may prevent mosquitoes to "waste" infectious blood meals on immune host and may thus facilitate perpetuation and spread of transmission. Conclusion Under certain conditions, host mortality may enhance transmission of WNV and similarly maintained arboviruses and thus facilitate their emergence and spread. The validity of the assumptions upon which this argument is built need to be empirically examined. PMID:17498307

    In a 4 year prospective community survey of 20,000 women randomly selected in North Arcot District of Tamil Nadu State in South India, the maternal mortality rates per 1,000 liveborn were estimated to be 17.4 and 16.6 for rural and semi-urban areas, respectively. The rates based only on direct causes were 11.9 in rural and 14.4 in semi-urban areas. As expected, these figures are considerably higher than those based on official or hospital statistics. Factors associated with such high mortality and the implications for programme planning and implementation are discussed. PMID:7855917

    Approximately 529,000 women die from pregnancy-related causes annually and almost all (99%) of these maternal deaths occur in developing nations. One of the United Nations' Millennium Development Goals is to reduce the maternal mortality rate by 75% by 2015. Causes of maternal mortality include postpartum hemorrhage, eclampsia, obstructed labor, and sepsis. Many developing nations lack adequate health care and family planning, and pregnant women have minimal access to skilled labor and emergency care. Basic emergency obstetric interventions, such as antibiotics, oxytocics, anticonvulsants, manual removal of placenta, and instrumented vaginal delivery, are vital to improve the chance of survival.

    Human enteric viruses occur in high concentrations in wastewater and can contaminate receiving environmental waters. Due to the lack of data on the prevalence of enteric viruses in New Caledonia, the presence and the concentrations of enteric viruses in wastewater and seawater were determined. Untreated wastewater and seawater samples were collected monthly for 1 year from a wastewater treatment plant (WWTP) and from the WWTP's outlet, located directly on a popular recreational beach. Samples were tested for norovirus genogroups I and II (NoV GI and GII), astroviruses (AsV), sapoviruses (SaV), enteroviruses (EV), hepatitis A viruses (HAV), rotaviruses (RoV), human adenoviruses (HAdV) and human polyomaviruses (HPyV). To support these data, faecal samples from cases of gastroenteritis were tested for the first time for NoV and detected in the population. NoV GI, NoV GII, EV, SaV, HAdV and HPyV were detected in all wastewaters, RoV in 75% and AsV in 67%. HAV were not detected in wastewater. Overall, 92% of seawater samples were positive for at least one virus. HPyV were detected most frequently in 92% of samples and at concentrations up to 7.7 × 10(3) genome copies/L. NoV GI, NoV GII, EV, SaV, RoV and HAdV were found in 33, 66, 41, 33, 16 and 66% of seawater samples, respectively. AsV were not detected in seawater. This study reports for the first time the presence of NoV and other enteric viruses in New Caledonia and highlights the year-round presence of enteric viruses in the seawater of a popular beach.

    Colleges and universities are high-risk settings for sexual and relationship violence. To address these problems, institutions of higher education have implemented prevention programs, many of which train students as potential bystanders who can step in to help diffuse risky situations, identify and challenge perpetrators, and assist victims. The impact of bystander sexual and relationship violence prevention programs on long-term behavior of bystanders has remained a key unanswered question for those who seek to offer the most effective programs as well as for policy makers. In this study, the researchers experimentally evaluated the effectiveness of the Bringing in the Bystander® in-person program. Participants were 948 1st-year college students of whom 47.8% were women and 85.2% identified as White (15% also identified as Hispanic in a separate question) between the ages of 18 and 24 at two universities (one a rural, primarily residential campus and the other an urban, highly commuter campus) in the northeastern United States. To date, this is the first study to have found positive behavior changes as long-lasting as 1 year following an educational workshop focusing on engaging bystanders in preventing sexual and relationship violence. Even so, many questions remain to be answered about prevention and intervention of this type. More prospective research is needed on bystander-focused prevention of these forms of violence to help understand and better predict the complicated relationships both between and among the attitudes and behaviors related to preventing sexual and relationship violence. In this regard, we make specific recommendations for designing and evaluating programs based on our findings relating to the importance of moderators, especially two key understudied ones, readiness to help and opportunity to intervene.

    Intensive measurements of submicron aerosol particles and their chemical composition were performed with an Aerosol Chemical Speciation Monitor (ACSM) at the Cabauw Experimental Site for Atmospheric Research (CESAR) in Cabauw, the Netherlands, sampling at 5 m height above ground. The campaign lasted nearly 1 year from July 2012 to June 2013 as part of the EU-FP7-ACTRIS project (Q-ACSM Network). Including equivalent black carbon an average particulate mass concentration of 9.50 µg m-3 was obtained during the whole campaign with dominant contributions from ammonium nitrate (45 %), organic aerosol (OA, 29 %), and ammonium sulfate (19 %). There were 12 exceedances of the World Health Organization (WHO) PM2.5 daily mean limit (25 µg m-3) observed at this rural site using PM1 instrumentation only. Ammonium nitrate and OA represented the largest contributors to total particulate matter during periods of exceedance. Source apportionment of OA was performed season-wise by positive matrix factorization (PMF) using the multilinear engine 2 (ME-2) controlled via the source finder (SoFi). Primary organic aerosols were attributed mainly to traffic (8-16 % contribution to total OA, averaged season-wise) and biomass burning (0-23 %). Secondary organic aerosols (SOAs, 61-84 %) dominated the organic fraction during the whole campaign, particularly on days with high mass loadings. A SOA factor which is attributed to humic-like substances (HULIS) was identified as a highly oxidized background aerosol in Cabauw. This shows the importance of atmospheric aging processes for aerosol concentration at this rural site. Due to the large secondary fraction, the reduction of particulate mass at this rural site is challenging on a local scale.

    Forest insects are major disturbances that induce tree mortality in eastern coniferous (or fir-spruce) forests in eastern North America. The spruce budworm (SBW) (Choristoneura fumiferana [Clemens]) is the most devastating insect causing tree mortality. However, the relative importance of insect-caused mortality versus tree mortality caused by other agents and how this relationship will change with climate change is not known. Based on permanent sample plots across eastern Canada, we combined a logistic model with a negative model to estimate tree mortality. The results showed that tree mortality increased mainly due to forest insects. The mean difference in annual tree mortality between plots disturbed by insects and those without insect disturbance was 0.0680 per year (P < 0.0001, T-test), and the carbon sink loss was about 2.87t C ha(-1) year(-1) larger than in natural forests. We also found that annual tree mortality increased significantly with the annual climate moisture index (CMI) and decreased significantly with annual minimum temperature (T min), annual mean temperature (T mean) and the number of degree days below 0°C (DD0), which was inconsistent with previous studies (Adams et al. 2009; van Mantgem et al. 2009; Allen et al. 2010). Furthermore, the results for the trends in the magnitude of forest insect outbreaks were consistent with those of climate factors for annual tree mortality. Our results demonstrate that forest insects are the dominant cause of the tree mortality in eastern Canada but that tree mortality induced by insect outbreaks will decrease in eastern Canada under warming climate.

  9. Reduction of drinking in problem drinkers and all-cause mortality.

    Alcohol consumption has been linked with considerable mortality, and reduction of drinking, especially of heavy drinking, has been suggested as one of the main measures to reduce alcohol-attributable mortality. Aggregate-level studies including but not limited to natural experiments support this suggestion; however, causality cannot be established in ecological analysis. The results of individual-level cohort studies are ambiguous. On the other hand, randomized clinical trials with problem drinkers show that brief interventions leading to a reduction of average drinking also led to a reduction of all-cause mortality within 1 year. The results of these studies were pooled and a model for reduction of drinking in heavy drinkers and its consequences for all-cause mortality risk was estimated. Ceteris paribus, the higher the level of drinking, the stronger the effects of a given reduction. Implications for interventions and public health are discussed. PMID:23531718

    Objective CT, an important diagnostic tool in the emergency department (ED), might increase the ED length of stay (LOS). Considering the issue of ED overcrowding, it is important to evaluate whether CT use delays or facilitates patient disposition in the ED. Design A retrospective 1-year cohort study. Setting 5 EDs within the same healthcare system dispersed nationwide in Taiwan. Participants All adult non-trauma patients who visited the 5 EDs from 1 July 2011 to 30 June 2012. Interventions Patients were grouped by whether or not they underwent a CT scan (CT and non-CT groups, respectively). Primary and secondary outcome measures The ED LOS and hospital LOS between patients who had and had not undergone CT scans were compared by stratifying different dispositions and diagnoses. Results CT use prolonged patient ED LOS among those who were directly discharged from the ED. Among patients admitted to the observation unit and then discharged, patients diagnosed with nervous system disease had shorter ED LOS if they underwent a CT scan. CT use facilitated patient admission to the general ward. CT use also accelerated patients' admission to the intensive care unit (ICU) for patients with nervous system disease, neoplasm and digestive disease. Finally, patients admitted to the general wards had shorter hospital LOS if they underwent CT scans in the ED. Conclusions CT use did not seem to have delayed patient disposition in ED. While CT use facilitated patient disposition if they were finally hospitalised, it mildly prolonged ED LOS in cases of patients discharged from the ED. PMID:27147387

    Background Bariatric surgery is one of the few effective treatments for morbid obesity but the weight loss and other health related outcomes for this procedure in large, diverse adolescent patient populations are not well characterized. Objective To analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. Setting BOLD data is collected from 423 surgeons at 360 facilities in the United States. Methods Main outcome measures included anthropometric and comorbidity status at baseline (n=890) and at 3 (n=786), 6 (n=541), and 12 (n=259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) age 11-to-19 years were included in the analyses. Results The overall one year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 kg versus 20 kg, P<0.001). Similar results were found for all other anthropometric changes and comparisons over one year between surgery types (P<0.001). In general, gastric bypass patients reported more improvement versus adjustable gastric band patients in comorbidities one year after surgery. There were a total of 45 readmissions among gastric bypass patients and 10 among adjustable gastric band patients with 29 and 8 reoperations required, respectively. Conclusions Weight loss at 3-, 6-, and 12-months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related comorbidities in morbidly obese adolescents for at least 1 year. PMID:22542199

    Background: We sought to compare mortality rates and related diagnoses in hospitalized patients with multiple sclerosis (MS), those with diabetes mellitus (DM), and the general hospitalized population (GHP). Methods: Patients who died between 2007 and 2011 were identified in the US hospital–based Premier Healthcare Database. Demographic information was collected, mortality rates calculated, and principal diagnoses categorized. Results: Of 55,152 unique patients with MS identified, 1518 died. Mean age at death was 10 years younger for the MS group (63.4 years) than for the DM (73.3 years) and GHP (73.1 years) groups. Age-adjusted mortality rates, based on the 2000 US Standard Million Population, were 1077, 1248, and 1133 per 100,000, respectively. Infection was the most common principal diagnosis at the hospital stay during which the patient died in the MS cohort (43.1% vs. 26.3% and 24.0% in the DM and GHP groups, respectively). Other common principal diagnoses in the MS group included pulmonary (17.5%) and cardiovascular (12.1%) disease. Septicemia/sepsis/septic shock was a secondary diagnosis for 50.7% of patients with MS versus 36.0% and 31.0% of patients in the DM and GHP cohorts, respectively. Conclusions: Patients with MS had a shorter life span than patients with DM or the GHP and were more likely to have a principal diagnosis of infection at their final hospital stay. However, the database was limited to codes recorded in the hospital; diagnoses received outside the hospital were not captured. PMID:27252603

    Objective to develop and validate the Drug Derived Complexity Index (DDCI), a predictive model derived from drug prescriptions able to stratify the general population according to the risk of death, unplanned hospital admission, and readmission, and to compare the new predictive index with the Charlson Comorbidity Index (CCI). Design Population-based cohort study, using a record-linkage analysis of prescription databases, hospital discharge records, and the civil registry. The predictive model was developed based on prescription patterns indicative of chronic diseases, using a random sample of 50% of the population. Multivariate Cox proportional hazards regression was used to assess weights of different prescription patterns and drug classes. The predictive properties of the DDCI were confirmed in the validation cohort, represented by the other half of the population. The performance of DDCI was compared to the CCI in terms of calibration, discrimination and reclassification. Setting 6 local health authorities with 2.0 million citizens aged 40 years or above. Results One year and overall mortality rates, unplanned hospitalization rates and hospital readmission rates progressively increased with increasing DDCI score. In the overall population, the model including age, gender and DDCI showed a high performance. DDCI predicted 1-year mortality, overall mortality and unplanned hospitalization with an accuracy of 0.851, 0.835, and 0.584, respectively. If compared to CCI, DDCI showed discrimination and reclassification properties very similar to the CCI, and improved prediction when used in combination with the CCI. Conclusions and Relevance DDCI is a reliable prognostic index, able to stratify the entire population into homogeneous risk groups. DDCI can represent an useful tool for risk-adjustment, policy planning, and the identification of patients needing a focused approach in everyday practice. PMID:26895073

    Mortality rates in the United States vary based on race, individual economic status and neighborhood. Correlations among these variables in most urban areas have limited what conclusions can be drawn from existing research. Our study employs a unique factorial design of race, sex, age and individual poverty status, measuring time to death as an objective measure of health, and including both neighborhood economic status and income inequality for a sample of middle-aged urban-dwelling adults (N = 3675). At enrollment, African American and White participants lived in 46 unique census tracts in Baltimore, Maryland, which varied in neighborhood economic status and degree of income inequality. A Cox regression model for 9-year mortality identified a three-way interaction among sex, race and individual poverty status (p = 0.03), with African American men living below poverty having the highest mortality. Neighborhood economic status, whether measured by a composite index or simply median household income, was negatively associated with overall mortality (p<0.001). Neighborhood income inequality was associated with mortality through an interaction with individual poverty status (p = 0.04). While racial and economic disparities in mortality are well known, this study suggests that several social conditions associated with health may unequally affect African American men in poverty in the United States. Beyond these individual factors are the influences of neighborhood economic status and income inequality, which may be affected by a history of residential segregation. The significant association of neighborhood economic status and income inequality with mortality beyond the synergistic combination of sex, race and individual poverty status suggests the long-term importance of small area influence on overall mortality.

    Background Studies on natural hazard mortality are most often hazard-specific (e.g. floods, earthquakes, heat), event specific (e.g. Hurricane Katrina), or lack adequate temporal or geographic coverage. This makes it difficult to assess mortality from natural hazards in any systematic way. This paper examines the spatial patterns of natural hazard mortality at the county-level for the U.S. from 1970–2004 using a combination of geographical and epidemiological methods. Results Chronic everyday hazards such as severe weather (summer and winter) and heat account for the majority of natural hazard fatalities. The regions most prone to deaths from natural hazards are the South and intermountain west, but sub-regional county-level mortality patterns show more variability. There is a distinct urban/rural component to the county patterns as well as a coastal trend. Significant clusters of high mortality are in the lower Mississippi Valley, upper Great Plains, and Mountain West, with additional areas in west Texas, and the panhandle of Florida, Significant clusters of low mortality are in the Midwest and urbanized Northeast. Conclusion There is no consistent source of hazard mortality data, yet improvements in existing databases can produce quality data that can be incorporated into spatial epidemiological studies as demonstrated in this paper. It is important to view natural hazard mortality through a geographic lens so as to better inform the public living in such hazard prone areas, but more importantly to inform local emergency practitioners who must plan for and respond to disasters in their community.

    Background The historical Japanese influenza vaccination program targeted at schoolchildren provides a unique opportunity to evaluate the indirect benefits of vaccinating high-transmitter groups to mitigate disease burden among seniors. Here we characterize the indirect mortality benefits of vaccinating schoolchildren based on data from Japan and the US. Methods We compared age-specific influenza-related excess mortality rates in Japanese seniors aged ≥65 years during the schoolchildren vaccination program (1978–1994) and after the program was discontinued (1995–2006). Indirect vaccine benefits were adjusted for demographic changes, socioeconomics and dominant influenza subtype; US mortality data were used as a control. Results We estimate that the schoolchildren vaccination program conferred a 36% adjusted mortality reduction among Japanese seniors (95%CI: 17–51%), corresponding to ∼1,000 senior deaths averted by vaccination annually (95%CI: 400–1,800). In contrast, influenza-related mortality did not change among US seniors, despite increasing vaccine coverage in this population. Conclusions The Japanese schoolchildren vaccination program was associated with substantial indirect mortality benefits in seniors. PMID:22087226

    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.

    The mortality experience of agricultural extension agents in the Cooperative Extension Service (CES) of the U.S. Department of Agriculture who died during the period January 1, 1970-December 31, 1979 (n = 1,495 white males) was evaluated in proportionate-mortality and case-control studies. The proportionate-mortality analysis was used to identify cancers that might be elevated in this occupational group compared with the U.S. white male population. All cancers with a significantly elevated proportionate-mortality ratio were more thoroughly evaluated in the case-control study, where there is presumably less of a selection bias in the comparison. In the case-control study, leukemia demonstrated a statistically significant linear trend with duration of employment as an extension agent. Smaller, but nonsignificant, trends were seen for non-Hodgkin's lymphoma, multiple myeloma, and brain cancer. The odds ratio for Hodgkin's disease and cancers of the colon, prostate, and kidney did not vary with the number of years on the job. These patterns resemble cancer risks seen among farmers, suggesting that agricultural factors may also play a role in the origin of these tumors among extension agents.

    New concerns have been raised regarding cardiovascular (CV) risks with testosterone (T) therapy (TTh). These concerns are based primarily on two widely reported retrospective studies. However, methodological flaws and data errors invalidate both studies as credible evidence of risk. One showed reduced adverse events by half in T-treated men but reversed this result using an unproven statistical approach. The authors subsequently acknowledged serious data errors including nearly 10% contamination of the dataset by women. The second study mistakenly used the rate of T prescriptions written by healthcare providers to men with recent myocardial infarction (MI) as a proxy for the naturally occurring rate of MI. Numerous studies suggest T is beneficial, including decreased mortality in association with TTh, reduced MI rate with TTh in men with the greatest MI risk prognosis, and reduced CV and overall mortality with higher serum levels of endogenous T. Randomized controlled trials have demonstrated benefits of TTh in men with coronary artery disease and congestive heart failure. Improvement in CV risk factors such as fat mass and glycemic control have been repeatedly demonstrated in T-deficient men treated with T. The current evidence does not support the belief that TTh is associated with increased CV risk or CV mortality. On the contrary, a wealth of evidence accumulated over several decades suggests that low serum T levels are associated with increased risk and that higher endogenous T, as well as TTh itself, appear to be beneficial for CV mortality and risk.

    Heart failure (HF) is a clinical syndrome, which is becoming a major public health problem in recent decades, due to its increasing prevalence, especially in the developed countries, mostly due to prolonged lifespan of the general population as well as the increased of HF patients. The HF treatment, particularly, new pharmacological and non-pharmacological agents, has markedly improved clinical outcomes of patients with HF including increased life expectancy and improved quality of life. However, despite the facts that mortality in HF patients has decreased, it still remains unacceptably high. This review of summarizes the evidence to date about the mortality of HF patients. Despite the impressive achievements in the pharmacological and non-pharmacological treatment of HF patients which has undeniably improved the survival of these patients, the mortality still remains high particularly among elderly, male and African-American patients. Patients with HF and reduced ejection fraction have higher mortality rates, most commonly due to cardiovascular causes, compared with patients HF and preserved ejection fraction. PMID:25550250

    Background Predicting risk of premature death is one of the most basic tasks in medicine and public health, but has proven difficult over the long term even with the best prognostic models. One popular strategy has been to improve prognostic models with candidate genes and other novel biomarkers. However, the gains in predictive power have been modest and the costs have been high, leading to a demand for cost-effective alternatives. We conducted a proof-of-principle investigation to examine whether simple, cheap, and non-invasive paper-and-pencil measures of social class and personality phenotype could improve the performance of one of the most widely used prediction models for all-cause mortality, the Charlson Comorbidity Index (CCI). Methods We used data from baseline and 25-year mortality follow-up of the UK Health and Lifestyle Study cohort. In a subset of the cohort, we first identified five psychosocial factors highly predictive of mortality: income, education, Type A personality, communalism (preference for the company of others), and “lie” scale (a measure of denial, putatively associated with ill-health). We then examined the predictive performance of the Charlson CCI with and without these measures in a validation subsample. Results Across 5, 10, 15, 20, and 25-year time horizons, the psychosocially augmented CCI showed substantially better discrimination (AUCs (95% CI) from .83 (.81, .85) to .84 (.83 .86)) than the CCI (AUCs from .74 (.71, .76) to .77 (.76 to .79)). These translated into net reclassification improvements from 27% (23%, 31%) to 35% (32%, 38%) of survivors and from 23% (17%, 30%) to 34% (17%, 30%) of decedents; and 23%–42% reductions in the Number Needed to Screen. Calibration improved at all time horizons except 25 years, where it was decreased. Conclusion Widespread attempts to improve prognostic models might consider not only novel biomarkers, but also psychosocial questionnaire measures. PMID:26421372

    Aim of the study In Poland testicular tumours are the most frequent cancer among men aged 20–44 years. Testicular tumour incidence since the 1980s and 1990s has been diversified geographically, with an increased risk of mortality in Wielkopolska Province, which was highlighted at the turn of the 1980s and 1990s. The aim of the study was the comparative analysis of the tendencies in incidence and death rates due to malignant testicular tumours observed among men in Poland and in Wielkopolska Province. Material and methods Data from the National Cancer Registry were used for calculations. The incidence/mortality rates among men due to malignant testicular cancer as well as the tendencies in incidence/death ratio observed in Poland and Wielkopolska were established based on regression equation. The analysis was deepened by adopting the multiple linear regression model. A p-value < 0.05 was arbitrarily adopted as the criterion of statistical significance, and for multiple comparisons it was modified according to the Bonferroni adjustment to a value of p < 0.0028. Calculations were performed with the use of PQStat v1.4.8 package. Results The incidence of malignant testicular neoplasms observed among men in Poland and in Wielkopolska Province indicated a significant rising tendency. The multiple linear regression model confirmed that the year variable is a strong incidence forecast factor only within the territory of Poland. A corresponding analysis of mortality rates among men in Poland and in Wielkopolska Province did not show any statistically significant correlations. Conclusions Late diagnosis of Polish patients calls for undertaking appropriate educational activities that would facilitate earlier reporting of the patients, thus increasing their chances for recovery. Introducing preventive examinations in the regions of increased risk of testicular tumour may allow earlier diagnosis. PMID:27095941

    OBJECTIVE: To study the levels and causes of maternal mortality in St. Petersburg, Russian Federation. METHODS: We collected data about all pregnancy-related deaths in St. Petersburg over the period 1992-2003 using several sources of information. An independent research group reviewed and classified all cases according to ICD-10 and the Confidential Enquiries into Maternal Deaths in the United Kingdom. We tested trends of overall and cause specific ratios (deaths per 100,000 births) for four 3-year intervals using the chi2 test. FINDINGS: The maternal mortality ratio for the study period was 43 per 100,000 live births. A sharp decline of direct obstetric deaths was observed from the first to fourth 3-year interval (49.8 for 1992-94 versus 18.5 for 2001-03). Sepsis and haemorrhage were the main causes of direct obstetric deaths. Among the total deaths from sepsis, 63.8% were due to abortion. Death ratios from sepsis declined significantly from the first to second study interval. In the last study interval (2001-03), 50% of deaths due to haemorrhage were secondary to ectopic pregnancies. The death ratio from thromboembolism remained low (2.9%) and stable throughout the study period. Among indirect obstetric deaths a non-significant decrease was observed for deaths from cardiac disease. Death ratios from infectious causes and suicides increased over the study period. CONCLUSIONS: Maternal mortality levels in St. Petersburg still exceed European levels by a factor of five. Improved management of abortion, emergency care for sepsis and haemorrhage, and better identification and control of infectious diseases in pregnancy, are needed. PMID:16628301

    Objectives. We have described national trends for the 5 leading external causes of injury mortality. Methods. We used negative binomial regression and annual underlying cause-of-death data for US residents for 2000 through 2009. Results. Mortality rates for unintentional poisoning, unintentional falls, and suicide increased by 128%, 71%, and 15%, respectively. The unintentional motor vehicle traffic crash mortality rate declined 25%. Suicide ranked first as a cause of injury mortality, followed by motor vehicle traffic crashes, poisoning, falls, and homicide. Females had a lower injury mortality rate than did males. The adjusted fall mortality rate displayed a positive age gradient. Blacks and Hispanics had lower adjusted motor vehicle traffic crash and suicide mortality rates and higher adjusted homicide rates than did Whites, and a lower unadjusted total injury mortality rate. Conclusions. Mortality rates for suicide, poisoning, and falls rose substantially over the past decade. Suicide has surpassed motor vehicle traffic crashes as the leading cause of injury mortality. Comprehensive traffic safety measures have successfully reduced the national motor vehicle traffic crash mortality rate. Similar efforts will be required to diminish the burden of other injury.

  11. Mortality studies of smelter workers.

    In view of the historic importance of smelter workers in the field of occupational medicine, it is surprising that until very recently little data was available on the mortality experience of these workers. The problem in most studies lies in identifying the smelter workers, because smelting, strictly speaking, refers to the melting of ores for the purposes of recovering metals, whereas smelters sometimes perform the operations of roasting, calcining, sintering, converting, and refining. These distinctions are not made in most mortality studies. Most mortality studies of smelter workers conducted to date have shown some excess in lung cancer. For lead, copper, cadmium, and nickel smelters a different etiologic agent has been proposed for each. These different explanations arise partly from different initial perspectives in conducting the studies. In this paper, data are presented on a current historical-prospective study of males who worked a year or more during the period January 1, 1940 to Decem
