Excess Mortality (excess + mortality)
Selected AbstractsLower Levels of Serum Albumin and Total Cholesterol Associated with Decline in Activities of Daily Living and Excess Mortality in a 12-Year Cohort Study of Elderly JapaneseJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 3 2008Tomonori Okamura MD OBJECTIVES: To examine the association between levels of serum albumin and total cholesterol (TC) and risk of subsequent mortality and future decline in activities of daily living (ADLs) in elderly people. DESIGN: Population-based cohort study. SETTING: National Integrated Project for Prospective Observation of Non-Communicable Disease and Its Trends in the Aged, 1980. PARTICIPANTS: One thousand eight hundred forty-four Japanese individuals aged 60 to 74 randomly selected throughout Japan and followed for 12.4 years. MEASUREMENTS: Decline in ADLs and mortality. RESULTS: After adjusting for other covariates, the multivariable odds ratios (ORs) of impaired ADLs were highest in the lowest albumin quartile (,40 g/L) for women. The multivariable OR of having a composite outcome of death or impaired ADL for the lowest albumin quartile compared with the highest was 1.56 (95% confidence interval (CI)=1.94,2.57) for men and 3.06 (95% CI=1.89,4.95) for women. Serum albumin was significantly and inversely associated with a composite outcome of death or impaired ADLs in the group below the median of TC in both sexes (multivariable OR for 1-g/L increase in serum albumin=0.88 for men (95% CI=0.79,0.97) and 0.79 for women (95% CI=0.72,0.87)), which was not significantly associated in the group with TC at or above the median. CONCLUSION: In the Japanese general population, low-normal serum albumin and TC levels are associated with loss of activity during old age, especially for women. [source] Causes of Male Excess Mortality: Insights from Cloistered PopulationsPOPULATION AND DEVELOPMENT REVIEW, Issue 4 2003Marc Luy The degree to which biological factors contribute to the existence and the widening of mortality differences by sex remains unclear. To address this question, a mortality analysis for the years 1890 to 1995 was performed comparing mortality data on more than 11,000 Catholic nuns and monks in Bavarian communities living in very nearly identical behavioral and environmental conditions with life table data for the general German population. While the mortality differences between women and men in the general German population increased considerably after World War II, they remained almost constant among the members of Bavarian religious orders during the entire observation period, with slight advantages for nuns. Thus, the higher differences observable in the general population cannot be attributed to biological factors. The different trends in sex-specific mortality between the general and the cloistered populations are caused exclusively by men in the general population who were unable to follow the trend in mortality reduction of women, nuns, and especially monks. Under the special environmental conditions of nuns and monks, biological factors appear to confer a maximum survival advantage for women of no more than one year in remaining life expectancy at young adult ages.

[source] Schizophrenia and physical health problemsACTA PSYCHIATRICA SCANDINAVICA, Issue 2009Y. Von Hausswolff-Juhlin Objective:, To estimate the prevalence of physical health problems in patients with schizophrenia, and to appraise the impact on mortality rates and quality of life (QoL) in such patients. Method:, A selective review of clinical articles relating to physical health such as cardiovascular disease, metabolic syndrome and QoL. In addition, current guidelines and recommendations for the monitoring of physical health in schizophrenia were reviewed. Results:, Cardiovascular events contribute most strongly to the excess mortality observed in schizophrenia. Other factors that contribute significantly include obesity, metabolic aberrations, smoking, alcohol, lack of exercise and poor diet , all of which might be targets for health promoting activities. Conclusion:, Physical health problems in patients with schizophrenia are common, and contribute to the excess mortality rate, as well as decreasing QoL. Many adverse physical factors are malleable in such patients, and physical benefit may be gained by following practical guidelines for their monitoring and improvement. [source] Smoking cessation in severe mental illness: what works?ADDICTION, Issue 7 2010Lindsay Banham ABSTRACT Aims The physical health of people with severe mental illness (SMI) is poor. Smoking-related illnesses are a major contributor to excess mortality and morbidity. An up-to-date review of the evidence for smoking cessation interventions in SMI is needed to inform clinical guidelines. Methods We searched bibliographic databases for relevant studies and independently extracted data. Included studies were randomized controlled trials (RCTs) of smoking cessation or reduction conducted in adult smokers with SMI. Interventions were compared to usual care or placebo. The primary outcome was smoking cessation and secondary outcomes were smoking reduction, change in weight, change in psychiatric symptoms and adverse events. Results We included eight RCTs of pharmacological and/or psychological interventions. Most cessation interventions showed moderate positive results, some reaching statistical significance. One study compared behavioural support and nicotine replacement therapy (NRT) to usual care and showed a risk ratio (RR) of 2.74 (95% CI 1.10,6.81) for short-term smoking cessation, which was not significant at longer follow-up. We pooled five trials that effectively compared bupropion to placebo giving an RR of 2.77 (95% CI 1.48,5.16), which was comparable to Hughes et al.'s 2009 figures for general population data; RR = 1.69 (95% CI 1.53,1.85). Smoking reduction data were too heterogeneous for meta-analysis, but results were generally positive. Trials suggest few adverse events. All trials recorded psychiatric symptoms and the most significant changes favoured the intervention groups over the control groups. Conclusions Treating tobacco dependence is effective in patients with SMI. Treatments that work in the general population work for those with severe mental illness and appear approximately equally effective. Treating tobacco dependence in patients with stable psychiatric conditions does not worsen mental state. [source] Breast cancer survival in England, Norway and Sweden: a population-based comparison,INTERNATIONAL JOURNAL OF CANCER, Issue 11 2010Henrik Møller Abstract Several international studies have found that survival from breast cancer is lower in the United Kingdom than in some other European countries. We have compared breast cancer survival between the national populations of England, Norway and Sweden, with a view to identifying subsets of patients with particularly good or adverse survival outcomes. We extracted cases of breast cancer in women diagnosed 1996,2004 from the national cancer registries of the 3 countries. The study comprised 303,657 English cases, 24,919 Norwegian cases and 57,512 cases from Sweden. Follow-up was in 2001,2004. The main outcome measures were 5-year cumulative relative survival and excess death rates, stratified by age and period of follow-up. In comparison with Norway and Sweden, the excess mortality in England was particularly pronounced in the first month and in the first year after diagnosis, and generally more marked in the oldest age groups. Compared with Norwegian patients, 81% of the excess deaths in the English patients occurred in the first 2 years after diagnosis. Our findings emphasise the importance of awareness of symptoms and early detection as the main strategy to improve breast cancer survival in the United Kingdom. [source] Dementia, cognitive impairment and mortality in persons aged 65 and over living in the community: a systematic review of the literatureINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 8 2001Michael E. Dewey Abstract Background No recent attempt has been made to synthesise information on mortality and dementia despite the theoretical and practical interest in the topic. Our objective was to estimate the influence on mortality of cognitive impairment and dementia. Methods Data sources were Medline, Embase, personal files and colleagues' records. Studies were considered if they included a majority of persons aged 65 and over at baseline either drawn from a total community sample or drawn from a random sample from the community. Samples from health care facilities were excluded. The search located 68 community studies. Effect sizes were extracted from the studies and if they were not included in the published studies, effect sizes were calculated where possible: this was possible for 23 studies of cognitive impairment and 32 of dementia. No attempt was made to contact authors for missing data. Results For the studies of cognitive impairment Fisher's method (a vote counting method), gave a p -value (from eight studies) of 0.00001. For studies of dementia, age-adjusted confidence intervals (CI) were pooled (odds ratio (OR) 2.63 with 95% CI 2.17 to 3.21 from six studies). Conclusions Levels of cognitive impairment commonly found in community studies give rise to an increased risk of mortality, and this appears to be true even for quite mild levels of impairment. The analysis confirms the increased risk of mortality for dementia, but reveals a dearth of information on the causes of the excess mortality and on possible effect modification by age, dementia subtype or other variables.

[source] Association Between Vertebral Fracture and Increased Mortality in Osteoporotic Patients,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 7 2003Tarja Jalava Abstract Determinants of mortality were studied in a prospective study of 677 women and men with primary or secondary osteoporosis. Prevalent vertebral fractures were associated with increased mortality, but other known predictors of mortality explain a significant proportion of the excess risk. Introduction: In population studies, prevalent vertebral fractures are associated with increased mortality. It is unknown whether this excess mortality is related to low bone mineral density or its determinants or whether there is an additional component associated with fracture itself. Methods: We studied 677 women and men with osteoporosis, 28,88 years old, of whom 352 had morphometrically determined vertebral fracture, to examine the risk and causes of mortality in patients with osteoporosis (defined densitometrically as a spine bone mineral density T-score < ,2.5 and ,3.0 for women and men, respectively, and/or one or more prevalent vertebral fractures without a history of significant trauma). The participants had enrolled in a double-blind placebo-controlled study in osteoporosis and were comprised of 483 women with postmenopausal osteoporosis, 110 women with secondary osteoporosis, and 84 men with osteoporosis of any cause. Demographics, medical history, and other measures of skeletal and nonskeletal health status were assessed at entry. Results: During a median follow-up of 3.2 years, 37 (5.5%) participants died, with 31 of these deaths occurring in those with prevalent vertebral fractures. Compared with participants who did not have a prevalent vertebral fracture, those with one or more fractures had a 4.4-fold higher (95% CI, 1.85, 10.6) mortality rate. After adjustment for predictors for poor health,including number of medications, number of diseases, use of oral corticosteroids, alcohol intake, serum albumin and erythrocyte sedimentation rate (ESR), renal function, height, weight, gender, and age,the point estimate of risk remained elevated but was no longer statistically significant (hazard ratio, 2.4; 95% CI. 0.93, 6.23). Conclusions: Prevalent vertebral fractures in osteoporotic patients are associated with increased mortality. Other known predictors of mortality can explain a significant proportion of the excess risk. [source] Integrated Management of Physician-delivered Alcohol Care for Tuberculosis Patients: Design and ImplementationALCOHOLISM, Issue 2 2010Shelly F. Greenfield Background:, While the integration of alcohol screening, treatment, and referral in primary care and other medical settings in the U.S. and worldwide has been recognized as a key health care priority, it is not routinely done. In spite of the high co-occurrence and excess mortality associated with alcohol use disorders (AUDs) among individuals with tuberculosis (TB), there are no studies evaluating effectiveness of integrating alcohol care into routine treatment for this disorder. Methods:, We designed and implemented a randomized controlled trial (RCT) to determine the effectiveness of integrating pharmacotherapy and behavioral treatments for AUDs into routine medical care for TB in the Tomsk Oblast Tuberculosis Service (TOTBS) in Tomsk, Russia. Eligible patients are diagnosed with alcohol abuse or dependence, are newly diagnosed with TB, and initiating treatment in the TOTBS with Directly Observed Therapy-Short Course (DOTS) for TB. Utilizing a factorial design, the Integrated Management of Physician-delivered Alcohol Care for Tuberculosis Patients (IMPACT) study randomizes eligible patients who sign informed consent into 1 of 4 study arms: (1) Oral Naltrexone + Brief Behavioral Compliance Enhancement Therapy (BBCET) + treatment as usual (TAU), (2) Brief Counseling Intervention (BCI) + TAU, (3) Naltrexone + BBCET + BCI + TAU, or (4) TAU alone. Results:, Utilizing an iterative, collaborative approach, a multi-disciplinary U.S. and Russian team has implemented a model of alcohol management that is culturally appropriate to the patient and TB physician community in Russia. Implementation to date has achieved the integration of routine alcohol screening into TB care in Tomsk; an ethnographic assessment of knowledge, attitudes, and practices of AUD management among TB physicians in Tomsk; translation and cultural adaptation of the BCI to Russia and the TB setting; and training and certification of TB physicians to deliver oral naltrexone and brief counseling interventions for alcohol abuse and dependence as part of routine TB care. The study is successfully enrolling eligible subjects in the RCT to evaluate the relationship of integrating effective pharmacotherapy and brief behavioral intervention on TB and alcohol outcomes, as well as reduction in HIV risk behaviors. Conclusions:, The IMPACT study utilizes an innovative approach to adapt 2 effective therapies for treatment of alcohol use disorders to the TB clinical services setting in the Tomsk Oblast, Siberia, Russia, and to train TB physicians to deliver state of the art alcohol pharmacotherapy and behavioral treatments as an integrated part of routine TB care. The proposed treatment strategy could be applied elsewhere in Russia and in other settings where TB control is jeopardized by AUDs. If demonstrated to be effective, this model of integrating alcohol interventions into routine TB care has the potential for expanded applicability to other chronic co-occurring infectious and other medical conditions seen in medical care settings. [source] Possibility that certain hypnotics might cause cancer in skinJOURNAL OF SLEEP RESEARCH, Issue 3 2008DANIEL F. KRIPKE Summary Fifteen epidemiologic studies have associated hypnotic drugs with excess mortality, especially excess cancer deaths. Until recently, insufficient controlled trials were available to demonstrate whether hypnotics actually cause any cancers. The US Food and Drug Administration (FDA) Approval History and Documents were accessed for zaleplon, eszopiclone and ramelteon. Since zolpidem was used as a comparison drug in zaleplon trials, some zolpidem data were also available. Incident cancers occurring during randomized hypnotics administration or placebo administration were tabulated. Combining controlled trials for the four drugs, there were 6190 participants given hypnotics and 2535 given placebo in parallel. There were eight mentions of incident non-melanoma skin cancers among participants receiving hypnotics but no comparable mentions of cancers among those receiving placebo (P = 0.064, one-tailed). There were also four mentions of incident tumors of uncertain malignancy among those receiving hypnotics but none among those receiving placebo, so combining uncertain and definite malignancies yielded a more significant contrast (P = 0.016). FDA files revealed that all four of the new hypnotics were associated with cancers in rodents. Three had been shown to be clastogenic. Together with the epidemiologic data and laboratory studies, the available evidence signals that new hypnotics may increase cancer risk. Due to limitations in available data, confirmatory research is needed. [source] Commissioned analysis of surgical performance using routine data: lessons from the Bristol inquiryJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 2 2002David J. Spiegelhalter The public inquiry into paediatric cardiac surgery at the Bristol Royal Infirmary commissioned the authors to design and conduct analyses of routine data sources to compare surgical outcomes between centres. Such analyses are necessarily complex in this context but were further hampered by the inherent inconsistencies and mediocre quality of the various sources of data. Three levels of analysis of increasing sophistication were carried out. The reasonable consistency of the results arising from different sources of data, together with a number of sensitivity analyses, led us to conclude that there had been excess mortality in Bristol in open heart operations on children under 1 year of age. We consider criticisms of our analysis and discuss the role of statisticians in this inquiry and their contribution to the final report of the inquiry. The potential statistical role in future programmes for monitoring clinical performance is highlighted. [source] The estimated benefits of vitamin D for GermanyMOLECULAR NUTRITION & FOOD RESEARCH (FORMERLY NAHRUNG/FOOD), Issue 8 2010A. Zittermann Abstract This article gives an overview of the vitamin D status in Germany, provides evidence for an independent association of vitamin D deficiency with various chronic diseases, and discusses preventive measures for improving vitamin D status in Germany. The prevalence of vitamin D insufficiency is 40,45% in the general German population. An additional 15,30% are vitamin D deficient. Vitamin D can prevent falls and osteoporotic fractures in older people. There is also accumulating evidence that vitamin D may prevent excess mortality and may probably prevent some chronic diseases that occur in early life such as type 1 diabetes and multiple sclerosis. Adherence to present sun safety policy (avoidance of the sun between 11 am and 3 pm) and dietary recommendations (5,10,,g daily for adults) would, however, definitively lead to vitamin D deficiency. The estimated cost saving effect of improving vitamin D status in Germany might be up to 37.5 billion , annually. It should be the goal of nutrition and medical societies to erase vitamin D deficiency in Germany within the next 5,10 years. To achieve this goal, the daily production of at least 25,,g of vitamin D in the skin or an equivalent oral intake should be guaranteed. [source] Weight loss causes increased mortality: prosOBESITY REVIEWS, Issue 1 2003T. I. A. Sørensen Summary There are many good reasons to expect that weight loss in overweight and obese subjects should lead to reduced mortality, not least because the general risk factor profile of several diseases responsible for the excess mortality associated with overweight and obesity improves with weight loss. However, observational long-term population studies have shown that weight loss in overweight subjects leads to increased long-term mortality, even if the studies are well controlled with regard to known confounding factors, including hazardous behaviour and underlying diseases that may lead to both weight loss and increased mortality. It seems unfeasible to wait for the multiple randomized clinical trials of sufficient quality, size and duration that may resolve this question. Therefore, the recommendations about weight loss must be based on the weaker evidence that can be obtained in short-term clinical trials and the observational population studies. Several studies have tried to address the problem by distinguishing intentional from unintentional weight loss, but only few do so by gathering information about the intention to lose weight before weight loss is observed. These studies suggest that intentional weight loss is associated with increased mortality. Recommendations to healthy overweight and obese subjects to lose weight must be based on an explicit weighing of the short-term well-documented benefits of weight loss, including improvement of quality of life, against the possible risk of an increased mortality in the long term [source] Social contexts, syndemics, and infectious disease in northern Aboriginal populations,AMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 2 2007D. Ann Herring Until the last half of the 20th century, infectious diseases dominated the health profile of northern North American Aboriginal communities. Research on the 1918 influenza pandemic exemplifies some of the ways in which the social context of European contact and ensuing economic developments affected the nature of infectious disease ecology as well as the frequency and severity of the problem. To understand these impacts it is necessary to consider the web of interactions among multiple pathogens, the biology of the human host, and the social environment in which people lived. At the very least, an understanding of the history of the impact of infectious diseases on northern North American communities requires attention not only to potential interactions among cocirculating pathogens, but their links to key social, historical, and economic factors that exacerbated their adverse effects and contributed to excess mortality.

[source] Mortality of older construction and craft workers employed at department of energy (DOE) nuclear sitesAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 9 2009John M. Dement PhD Abstract Background The U.S. Department of Energy (DOE) established medical screening programs at the Hanford Nuclear Reservation, Oak Ridge Reservation, the Savannah River Site, and the Amchitka site starting in 1996. Workers participating in these programs have been followed to determine their vital status and mortality experience through December 31, 2004. Methods A cohort of 8,976 former construction workers from Hanford, Savannah River, Oak Ridge, and Amchitka was followed using the National Death Index through December 31, 2004, to ascertain vital status and causes of death. Cause-specific standardized mortality ratios (SMRs) were calculated based on US death rates. Results Six hundred and seventy-four deaths occurred in this cohort and overall mortality was slightly less than expected (SMR,=,0.93, 95% CI,=,0.86,1.01), indicating a "healthy worker effect." However, significantly excess mortality was observed for all cancers (SMR,=,1.28, 95% CI,=,1.13,1.45), lung cancer (SMR,=,1.54, 95% CI,=,1.24,1.87), mesothelioma (SMR,=,5.93, 95% CI,=,2.56,11.68), and asbestosis (SMR,=,33.89, 95% CI,=,18.03,57.95). Non-Hodgkin's lymphoma was in excess at Oak Ridge and multiple myeloma was in excess at Hanford. Chronic obstructive pulmonary disease (COPD) was significantly elevated among workers at the Savannah River Site (SMR,=,1.92, 95% CI,=,1.02,3.29). Conclusions DOE construction workers at these four sites were found to have significantly excess risk for combined cancer sites included in the Department of Labor' Energy Employees Occupational Illness Compensation Program (EEOCIPA). Asbestos-related cancers were significantly elevated. Am. J. Ind. Med. 52:671,682, 2009. © 2009 Wiley-Liss, Inc. [source] Mortality among sheet metal workers participating in a medical screening programAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 8 2009John Dement PhD Abstract Background The Sheet Metal Occupational Health Institute Trust (SMOHIT) was formed in 1985 to examine the health hazards of the sheet metal industry in the U.S. and Canada through an asbestos disease screening program. A study of mortality patterns among screening program participants was undertaken. Methods A cohort of 17,345 individuals with 20 or more years in the trade and who participated in the asbestos disease screening program were followed for vital status and causes of death between 1986 and 2004. Data from the screening program included chest X-ray results by International Labour Office (ILO) criteria and smoking history. Standardized mortality ratios (SMRs) by cause were generated using U.S. death rates and Cox proportional hazards models were used to investigate lung cancer risk relative to chest X-ray changes while controlling for smoking. Results A significantly reduced SMR of 0.83 (95% CI,=,0.80,0.85) was observed for all causes combined. Statistically significant excess mortality was observed for pleural cancers, mesothelioma, and asbestosis in the SMR analyses. Both lung cancer and COPD SMRs increased consistently and strongly with increasing ILO profusion score. In Cox models, which controlled for smoking, increased lung cancer risk was observed among workers with ILO scores of 0/1 (RR,=,1.17, 95% CI,=,0.89,1.54), with a strong trend for increasing lung cancer risk with increasing ILO profusion score >0/0. Conclusions Sheet metal workers are at increased risk for asbestos-related diseases. This study contributes to the literature demonstrating asbestos-related diseases among workers with largely indirect exposures and supports an increased lung cancer risk among workers with low ILO profusion scores.

[source] Urban-Rural Mortality Differentials: An Unresolved DebatePOPULATION AND DEVELOPMENT REVIEW, Issue 1 2003Robert Woods Historians and demographers have long debated the existence, causes, and consequences of historical differences between urban and rural mortality levels. In Europe it has been usual to observe excess mortality in cities compared to the countryside, but in East Asia, by contrast, it has been found that urban areas had relatively favorable mortality environments. The debate continues because a number of pertinent questions remain to be resolved. For example, the way in which mortality is measured may influence the apparent extent of the differential, as may the way in which"urban" and"rural" are defined. Cultural factors need to be taken into account, including the practices of childrearing and the conventions surrounding baptism. Examples drawn from Japan, China, England, and France illustrate the issues involved in comparative analysis, while the urban-rural mortality continuum is examined for nineteenth-century England and Wales using log-normal distributions. [source] Sex differentials in frailty in medieval EnglandAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 2 2010Sharon N. DeWitte Abstract In most modern populations, there are sex differentials in morbidity and mortality that favor women. This study addresses whether such female advantages existed to any appreciable degree in medieval Europe. The analyses presented here examine whether men and women with osteological stress markers faced the same risks of death in medieval London. The sample used for this study comes from the East Smithfield Black Death cemetery in London. The benefit of using this cemetery is that most, if not all, individuals interred in East Smithfield died from the same cause within a very short period of time. This allows for the analysis of the differences between men and women in the risks of mortality associated with osteological stress markers without the potential confounding effects of different causes of death. A sample of 299 adults (173 males, 126 females) from the East Smithfield cemetery was analyzed. The results indicate that the excess mortality associated with several osteological stress markers was higher for men than for women. This suggests that in this medieval population, previous physiological stress increased the risk of death for men during the Black Death to a greater extent than was true for women. Alternatively, the results might indicate that the Black Death discriminated less strongly between women with and without pre-existing health conditions than was true for men. These results are examined in light of previous analyses of East Smithfield and what is known about diet and sexually mediated access to resources in medieval England.

[source] Incidence and mortality of interstitial lung disease in rheumatoid arthritis: A population-based studyARTHRITIS & RHEUMATISM, Issue 6 2010Tim Bongartz Objective Interstitial lung disease (ILD) has been recognized as an important comorbidity in rheumatoid arthritis (RA). We undertook the current study to assess incidence, predictors, and mortality of RA-associated ILD. Methods We examined a population-based incidence cohort of patients with RA and a matched cohort of individuals without RA. All subjects were followed up longitudinally. The lifetime risk of ILD was estimated. Cox proportional hazards models were used to compare the incidence of ILD between cohorts, to investigate predictors, and to explore the impact of ILD on survival. Results Patients with RA (n = 582) and subjects without RA (n = 603) were followed up for a mean of 16.4 and 19.3 years, respectively. The lifetime risk of developing ILD was 7.7% for RA patients and 0.9% for non-RA subjects. This difference translated into a hazard ratio (HR) of 8.96 (95% confidence interval [95% CI] 4.02,19.94). The risk of developing ILD was higher in RA patients who were older at the time of disease onset, in male patients, and in individuals with more severe RA. The risk of death for RA patients with ILD was 3 times higher than in RA patients without ILD (HR 2.86 [95% CI 1.98,4.12]). Median survival after ILD diagnosis was only 2.6 years. ILD contributed ,13% to the excess mortality of RA patients when compared with the general population. Conclusion Our results emphasize the increased risk of ILD in patients with RA. The devastating impact of ILD on survival provides evidence that development of better strategies for the treatment of ILD could significantly lower the excess mortality among individuals with RA. [source] Could accelerated aging explain the excess mortality in patients with seropositive rheumatoid arthritis?ARTHRITIS & RHEUMATISM, Issue 2 2010Cynthia S. Crowson Objective To determine whether the mortality pattern in patients with seropositive rheumatoid arthritis (RA) is consistent with the concept of accelerated aging, by comparing the observed mortality rates in patients with RA with the age-accelerated mortality rates from the general population. Methods A population-based inception cohort of patients with seropositive RA (according to the American College of Rheumatology 1987 criteria) was assembled and followed up for vital status until July 1, 2008. The expected mortality rate was obtained by applying the death rates from the general population to the age, sex, and calendar year distribution of the RA population. The observed mortality was estimated using Kaplan-Meier methods. Acceleration factors for the expected mortality were estimated in accelerated failure time models. Results A total of 755 patients with seropositive RA (mean age 55.6 years, 69% women) were followed up for a mean of 12.5 years, during which 315 patients died. The expected median survival was age 82.4 years, whereas the median survival of the RA patients was age 76.7 years. Results of statistical modeling suggested that, in terms of mortality rates, patients with RA were effectively 2 years older than actual age at RA incidence, and thereafter the patients underwent 11.4 effective years of aging for each 10 years of calendar time. Conclusion The overall observed mortality experience of patients with seropositive RA is consistent with the hypothesis of accelerated aging. The causes of accelerated aging in RA deserve further investigation. [source] Morbidity and mortality in rheumatoid arthritis patients with prolonged therapy-induced lymphopenia: Twelve-year outcomesARTHRITIS & RHEUMATISM, Issue 2 2008Alice R. Lorenzi Objective To assess immunologically relevant outcomes in a cohort of rheumatoid arthritis (RA) patients with prolonged therapy-induced lymphopenia. Methods Morbidity (infection or malignancy) and mortality were assessed in 53 RA patients who were treated with the lymphocytotoxic monoclonal antibody alemtuzumab between 1991 and 1994. Data were obtained by interview, medical record review, and Office for National Statistics mortality monitoring. Lymphocyte subsets were enumerated by flow cytometry. A retrospective, matched-cohort study of mortality was performed with 102 control subjects selected from the European League Against Rheumatism database of patients with rheumatic disorders. Results Lymphopenia persisted in the patients: median CD3+CD4+, CD3+CD8+, CD19+, and CD56+ lymphocyte counts measured at a median followup of 11.8 years from the first administration of alemtuzumab were 0.50 × 109/liter, 0.26 × 109/liter, 0.11 × 109/liter, and 0.09 × 109/liter, respectively. Twenty-seven of 51 cases and 46 of 101 controls with available data had died, yielding a mortality rate ratio of 1.20 (95% confidence interval 0.72,1.98). Causes of death were similar to those that would be expected in a hospital-based RA cohort. No opportunistic infections were noted, and only 3 infections were documented following 36 elective orthopedic procedures. Conclusion Despite continued lymphopenia 11.8 years after therapy, our patient cohort did not exhibit excess mortality or unusual infection-related morbidity, and surgery was well tolerated. These data should be reassuring for clinicians and patients who are considering lymphocytotoxic or other immunomodulatory therapy for RA. [source] Contribution of congestive heart failure and ischemic heart disease to excess mortality in rheumatoid arthritis,,ARTHRITIS & RHEUMATISM, Issue 1 2006Paulo J. Nicola Objective Although mortality among patients with rheumatoid arthritis (RA) is higher than in the general population, the relative contribution of comorbid diseases to this mortality difference is not known. This study was undertaken to evaluate the contribution of congestive heart failure (CHF) and ischemic heart disease (IHD), including myocardial infarction, to the excess mortality in patients with RA, compared with that in individuals without RA. Methods We assembled a population-based inception cohort of individuals living in Rochester, Minnesota, in whom RA (defined according to the criteria of the American College of Rheumatology [formerly, the American Rheumatism Association]) first developed between 1955 and 1995, and an age- and sex-matched non-RA cohort. All subjects were followed up until either death, migration from the county, or until 2001. Detailed information from the complete medical records was collected. Statistical analyses included the person-years method, cumulative incidence, and Cox regression modeling. Attributable risk analysis techniques were used to estimate the number of RA deaths that would be prevented if the incidence of CHF was the same in patients with RA and non-RA subjects. Results The study population included 603 patients with RA and 603 subjects without RA. During followup, there was an excess of 123 deaths among patients with RA (345 RA deaths occurred, although only 222 such deaths were expected). The mortality rates among patients with RA and non-RA subjects were 39.0 and 29.2 per 1,000 person-years, respectively. There was a significantly higher cumulative incidence of CHF (but not IHD) in patients with RA compared with non-RA subjects (37.1% versus 27.7% at 30 years of followup, respectively; P < 0.001). The risk of death associated with either CHF or IHD was not significantly different between patients with RA and non-RA subjects. If the risk of developing CHF was the same in patients with RA and individuals without RA, the overall mortality rate difference between RA and non-RA hypothetically would be reduced from 9.8 to 8.0 excess deaths per 1,000 person-years; that is, 16 (13%) of the 123 excess deaths could be prevented. Conclusion CHF, rather than IHD, appears to be an important contributor to the excess overall mortality among patients with RA. CHF contributes to this excess mortality primarily through the increased incidence of CHF in RA, rather than increased mortality associated with CHF in patients with RA compared with non-RA subjects. Eliminating the excess risk of CHF in patients with RA could significantly improve their survival. [source] Health status differentials across rural and remote AustraliaAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 1 2009Andrew Phillips Abstract This paper describes mortality and disease patterns across five broad remoteness categories of Australia, with reference to the context in which those outcomes develop and are treated. Health and its outcomes become worse as remoteness increases. Some of this phenomenon reflects proportionally greater numbers of Aboriginal and Torres Strait Islander people in remote areas coupled with their poorer overall health outcomes; however, mortality for non-indigenous people is clearly higher outside compared with inside major cities. Migration of people seeking services likely reduces the size of interregional health disparity. Poorer health outcomes stem from worse risk factor profiles and average lower levels of income and of education, poorer physical and financial access to services, higher occupational and environmental risk, as well as factors unique to Aboriginal and Torres Strait Islander health. Little is known about the health benefits of living outside major cities. Diseases of the circulatory system and injuries account, respectively, for 40% and 18% of the excess mortality outside major cities. Death rates are declining over time in all (particularly remote) areas, but rates of death due to certain lung diseases in rural women are not, and rates of suicide have increased in remote areas. Ostensibly, prevalence of mental ill-health appears roughly similar in all remoteness areas. Dental health is poorer and disability is more prevalent outside major cities, as are a range of infectious diseases. Although pertinent, the effects on rural health of climate change and resource degradation generally have not been addressed in this paper.
