Perioperative Outcome and Long-Term Mortality for Heart Failure Patients Undergoing Intermediate- and High-Risk Noncardiac Surgery: Impact of Left Ventricular Ejection Fraction

CONGESTIVE HEART FAILURE, Issue 2 2010
Kirsten O. Healy MD
The impact of left ventricular ejection fraction (LVEF) on outcome in patients with heart failure (HF) undergoing noncardiac surgery has not been extensively evaluated. In this study, 174 patients (mean age, 75±12 years, 47% male, mean LVEF (47%±18%) underwent intermediate- or high-risk noncardiac surgery. Patients were stratified by LVEF, and adverse perioperative complications were identified and compared. Adverse perioperative events occurred in 53 patients (30.5%), including 14 (8.1%) deaths within 30 days, 26 (14.9%) myocardial infarctions, and 44 (25.3%) HF exacerbations. Among the factors associated with adverse perioperative outcomes in the first 30 days were advanced age (>80 years), diabetes, and a severely decreased LVEF (<30%). Long-term mortality was high, and Cox proportional hazards analysis demonstrated that LVEF was an independent risk factor for long-term mortality.

Short- and Long-Term Mortality after an Acute Illness for Elderly Whites and Blacks

HEALTH SERVICES RESEARCH, Issue 4 2008
Daniel Polsky
Objective. To estimate racial differences in mortality at 30 days and up to 2 years following a hospital admission for the elderly with common medical conditions. Data Sources. The Medicare Provider Analysis and Review File and the VA Patient Treatment File from 1998 to 2002 were used to extract patients 65 or older admitted with a principal diagnosis of acute myocardial infarction, stroke, hip fracture, gastrointestinal bleeding, congestive heart failure, or pneumonia. Study Design. A retrospective analysis of risk-adjusted mortality after hospital admission for blacks and whites by medical condition and in different hospital settings. Principal Findings. Black Medicare patients had consistently lower adjusted 30-day mortality than white Medicare patients, but the initial survival advantage observed among blacks dissipated beyond 30 days and reversed by 2 years. For VA hospitalizations similar patterns were observed, but the initial survival advantage for blacks dissipated at a slower rate. Conclusions. Racial disparities in health are more likely to be generated in the posthospital phase of the process of care delivery rather than during the hospital stay. The slower rate of increase in relative mortality among black VA patients suggests an integrated health care delivery system like the VA may attenuate racial disparities in health. [source]

Differences in Long-term Mortality for Different Emergency Department Presenting Complaints

ACADEMIC EMERGENCY MEDICINE, Issue 1 2008
Urban Safwenberg MD
Abstract Objectives:, To characterize long-term mortality based on previous emergency department (ED) presenting complaints. Methods:, The authors followed, for 10 years, all of the 12,667 nonsurgical patients visiting an ED during 1995/1996. Differences in standardized mortality ratio (SMR) depending on presenting complaints were then investigated. Results:, During follow-up, 5,324 deaths occurred (mortality rate 6.6 per 100 person-years at risk), giving a SMR of 1.33 (95% CI = 1.30 to 1.37, p < 0.001) when compared with the expected mortality in the catchment area. Different presenting complaints were associated with different long-term mortality rates, independent of age and gender (p < 0.0001). The subjects with seizures had the highest SMR (2.62, 95% CI = 2.13 to 3.22) followed by intoxications (2.51, 95% CI = 2.11 to 2.98), asthmalike symptoms (1.84, 95% CI = 1.65 to 2.06), and hyperglycemia (1.67, 95% CI = 1.42 to 1.95). The largest complaint group, chest pain, had a 20% higher mortality rate than the background population (95% CI = 1.13 to 1.26). Patients with a discharge diagnosis of myocardial infarction, but without chest pain as the presenting complaint, had an increased long-term mortality (hazard ratio [HR] 1.70, 95% CI = 1.15 to 2.42) compared to the group with chest pain. In contrast, stroke patients without strokelike symptoms had a reduced mortality (HR 0.74, 95% CI = 0.65 to 0.84) compared to patients with strokelike symptoms. Conclusions:, Long-term age- and gender-adjusted mortality is the highest with seizures out of 33 presenting complaints and differs markedly between different ED admission complaints. Furthermore, depending on the admission complaint, long-term mortality differs within the same discharge diagnosis. Hence, the presenting complaint adds unique information to the discharge diagnosis regarding long-term mortality in nonsurgical patients. [source]

Neutrophil to Lymphocyte Ratio as a Predictor of Long-term Mortality in African Americans Undergoing Percutaneous Coronary Intervention

CLINICAL CARDIOLOGY, Issue 12 2009
Shyam Poludasu MD
Abstract Background Neutrophil to lymphocyte ratio (N/L ratio) has been shown to predict long-term mortality in patients undergoing percutaneous coronary intervention (PCI). African Americans have been shown to have lower mean neutrophil counts compared to whites. The usefulness of the N/L ratio in predicting long-term mortality in African Americans undergoing PCI is unknown. Methods We evaluated a total of 372 African American patients (327 patients with lower N/L ratio [<3.5] and 45 patients with higher N/L ratio [,3.5]) who underwent PCI during January 2003 to August 2005. The primary endpoint was all-cause mortality at a median follow-up to 3.6 years. Results During the median ( ± SD) follow-up period of 3.6 ± 1 years, there were a total of 48 deaths. The mortality rate was 10.4% in the group with a lower N/L ratio and 31.1% in the group with a higher N/L ratio (unadjusted p < 0.001). After adjustment for covariates with significant impact on mortality, N/L ratio was still a strong and independent predictor of long-term mortality with a hazard ratio (HR) of 2.1 (95% confidence interval [CI]: 1.1,4; p = 0.02). N/L ratio was also found to be a strong and independent predictor of long-term mortality even when analyzed as a categorical variable with 3 groups (HR of 0.39 for lower tertile compared to the upper tertile, 95% CI: 0.19,0.81; p = 0.012) and as a continuous variable (p = 0.002). Conclusion N/L ratio is a powerful independent predictor of long-term mortality in African Americans undergoing PCI. Copyright © 2009 Wiley Periodicals, Inc. [source]

Long-term mortality from pleural and peritoneal cancer after exposure to asbestos: Possible role of asbestos clearance

INTERNATIONAL JOURNAL OF CANCER, Issue 4 2008
Francesco Barone-Adesi
Abstract Models based on the multistage theory of carcinogenesis predict that the rate of mesothelioma increases monotonically as a function of time since first exposure (TSFE) to asbestos. Predictions of long-term mortality (TSFE , 40 years) are, however, still untested, because of the limited follow-up of most epidemiological studies. Some authors have suggested that the increase in mesothelioma rate with TSFE might be attenuated by clearance of asbestos from the lungs. We estimated mortality time trends from pleural and peritoneal cancer in a cohort of 3,443 asbestos-cement workers, followed for more than 50 years. The functional relation between mesothelioma rate and TSFE was evaluated with various regression models. The role of asbestos clearance was explored using the traditional mesothelioma multistage model, generalized to include a term representing elimination over time. We observed 139 deaths from pleural and 56 from peritoneal cancer during the period 1950,2003. The rate of pleural cancer increased during the first 40 years of TSFE and reached a plateau thereafter. In contrast, the rate of peritoneal cancer increased monotonically with TSFE. The model allowing for asbestos elimination fitted the data better than the traditional model for pleural (p = 0.02) but not for peritoneal cancer (p = 0.22). The risk for pleural cancer, rather than showing an indefinite increase, might reach a plateau when a sufficiently long time has elapsed since exposure. The different trends for pleural and peritoneal cancer might be related to clearance of the asbestos from the workers' lungs. © 2008 Wiley-Liss, Inc. [source]

Long-term mortality among young ischemic stroke patients in western Norway

ACTA NEUROLOGICA SCANDINAVICA, Issue 3 2007
U. Waje-Andreassen
Objectives,,, To obtain data on long-term mortality among young ischemic stroke patients compared with controls in this population-based study. Material and methods ,, We used Kaplan,Meier survival analysis to compare 232 patients aged 15,49 years with first-ever cerebral infarction in 1988,1997 and 453 controls followed from inclusion to death or 1 August 2005 for 2515 and 5558 person-years respectively. In a subanalysis of 192 patients, we compared risk factor variables using the Kaplan,Meier method and log-rank testing. We applied a Cox proportional hazards model to adjust for multiple risk factors. Results ,, Forty-five patients and nine controls died during follow-up (P < 0.0005). Independent risk factors for mortality were active tumor disease (P < 0.0005), high consumption of alcohol (P < 0.0005), coronary atherosclerosis (P < 0.001), living alone (P < 0.02), seizures (P < 0.04) and smoking (P = 0.08). Conclusions ,, Long-term mortality was significantly increased among young stroke patients, mainly due to such lifestyle factors as high consumption of alcohol and tobacco. [source]

Long-term mortality and retinopathy in type 1 diabetes

ACTA OPHTHALMOLOGICA, Issue thesis1 2010
Jakob Grauslund
The incidence of type 1 diabetes is increasing in Denmark as well as the rest of the world. Due to diabetes-related micro- and macrovascular complications, the morbidity and the mortality is higher among type 1 diabetic patients. The aim of this thesis was to examine a population-based cohort of 727 type 1 diabetic patients from Fyn County, Denmark, with an onset of diabetes before 1 July 1973 in order to: 1,Evaluate the all-cause mortality rates and the influence of sex, duration of diabetes and calendar year of diagnosis in a 33-year follow-up (Paper I). 2,Examine glycaemic regulation, lipids and renal dysfunction as risk factors for all-cause mortality, cardiovascular mortality and IHD (Paper II). 3,Estimate the prevalence of DR as well as the 25-year incidence of PDR and associated risk factors in long-time surviving patients (Paper III). 4,To compare the grading of DR between ETDRS seven standard field 30° stereoscopic colour films and nine field 45° monoscopic digital colour images in long-term surviving patients (Paper IV). In the years 1973,2006 an overall MR of 22.3 per 1000 person-years was found. Furthermore a relative mortality of 3.4 was found as compared to the general population in Denmark. The relative mortality was especially high for patients aged 30,39 (SMR 9.8). There was a tendency towards a better survival for patients diagnosed after 1964. This was especially seen for men. Diabetes was the most common cause of death for those who died in the group. In 1993,1996 blood samples were drawn and glycaemic regulation, lipids and renal markers were subsequently used as predictors of all-cause mortality, cardiovascular mortality and ischaemic heart disease. Glycaemic regulation, dyslipidaemia and creatinine were all significantly associated with all three endpoints. Furthermore, variations in glycaemic control were also identified as a risk factor for overall mortality. Two hundred and one patients were examined for diabetic retinopathy in 1981,1982 and 2007,2008. At follow-up, 97.0% had DR and 42.9% of all patients without PDR at baseline developed this during the follow-up period. Patients who had had a poor glycaemic regulation as well as those who had NPDR at baseline were more likely to develop PDR than the remaining patients. On the other hand, other risk factors such as high blood pressure and proteinuria did not predict PDR. In the comparative study between ETDRS seven standard field 30° stereoscopic colour films and nine field 45° monoscopic digital colour images, 43 eyes of 43 patients were examined in 2008. A poor correlation was found between the two methods: only 29.3% were graded alike. In the remaining, the level of DR was graded higher in the digital photos. Among these, PDR was detected in three eyes using digital photos but remained undetected on all films. This suggests that digital photos with wide fields are the best way to detect DR in long-term type 1 diabetic patients. Overall, it is concluded that mortality is still higher among type 1 diabetic patients. This depends, among other things, on glycaemic regulation, lipid status and, partly, renal dysfunction. Diabetic retinopathy is almost universal in long-term type 1 diabetic patients, and almost half of all patients will develop PDR in 25 years. Nine field digital photos provide the best grading of retinopathy in long-term type 1 diabetic patients. [source]

Increased prevalence of cardiovascular disease in Type 2 diabetic patients with non-alcoholic fatty liver disease

DIABETIC MEDICINE, Issue 4 2006
G. Targher
Abstract Aims, To estimate the prevalence of cardiovascular disease (CVD) in Type 2 diabetic patients with and without non-alcoholic fatty liver disease (NAFLD), and to assess whether NAFLD is independently related to prevalent CVD. Methods, We studied 400 Type 2 diabetic patients with NAFLD and 400 diabetic patients without NAFLD who were matched for age and sex. Main outcome measures were prevalent CVD (as ascertained by medical history, physical examination, electrocardiogram and echo-Doppler scanning of carotid and lower limb arteries), NAFLD (by ultrasonography) and presence of the metabolic syndrome (MetS) as defined by the World Health Organization or Adult Treatment Panel III criteria. Results, The prevalences of coronary (23.0 vs. 15.5%), cerebrovascular (17.2 vs. 10.2%) and peripheral (12.8 vs. 7.0%) vascular disease were significantly increased in those with NAFLD as compared with those without NAFLD (P < 0.001), with no differences between sexes. The MetS (by any criteria) and all its individual components were more frequent in NAFLD patients (P < 0.001). In logistic regression analysis, male sex, age, smoking history and MetS were independently related to prevalent CVD, whereas NAFLD was not. Conclusions, The prevalence of CVD is increased in patients with Type 2 diabetes and NAFLD in association with an increased prevalence of MetS as compared with diabetic patients without NAFLD. Follow-up studies are necessary to determine whether this higher prevalence of CVD among diabetic patients with NAFLD affects long-term mortality. Diabet. Med. (2006) [source]

Mortality risk up to 25 years after initiation of treatment among 420 Swedish women with alcohol addiction

ADDICTION, Issue 3 2009
Brit Haver
ABSTRACT Aims Women treated for alcohol addiction have mortality rates three to five times those of women from the general population (GP). However, these figures may be inflated because socially disadvantaged women with advanced drinking careers are over-represented in previous studies. Our aim was to study the long-term mortality of socially relatively well-functioning patients coming to their first treatment, compared to matched GP controls. Design The mortality rates and causes of death were compared between patients and their matched GP controls, using data from the Causes of Death Register throughout the follow-up period (0,25 years). Setting A specialized treatment programme for women only, called ,Early treatment for Women with Alcohol Addiction' (EWA) at the Karolinska Hospital, Stockholm, Sweden. Participants Subjects (n = 420) receiving their first treatment at the EWA programme, compared to a group of matched GP women (n = 2037). Findings The women patients had significantly higher mortality than matched GP controls throughout the whole follow-up period, with a relative risk of 2.4. However, the younger women had four times higher mortality than their matched controls. The peak of deaths occurred during the first 5 years, and alcohol-related causes of death were highly over-represented, as were uncertain suicides and accidents. Conclusions First-time-treated women with alcohol addiction have a substantially lower mortality than reported previously from clinical samples, except for the youngest group. Our figures were corrected for confounding factors such as socio-demographic status. We believe our results could apply to broader groups of heavy drinking women, inside or outside specialized treatment settings. [source]

Exposure to opioid maintenance treatment reduces long-term mortality

ADDICTION, Issue 3 2008
Amy Gibson
ABSTRACT Aims To (i) examine the predictors of mortality in a randomized study of methadone versus buprenorphine maintenance treatment; (ii) compare the survival experience of the randomized subject groups; and (iii) describe the causes of death. Design Ten-year longitudinal follow-up of mortality among participants in a randomized trial of methadone versus buprenorphine maintenance treatment. Setting Recruitment through three clinics for a randomized trial of buprenorphine versus methadone maintenance. Participants A total of 405 heroin-dependent (DSM-IV) participants aged 18 years and above who consented to participate in original study. Measurements Baseline data from original randomized study; dates and causes of death through data linkage with Births, Deaths and Marriages registries; and longitudinal treatment exposure via State health departments. Predictors of mortality examined through survival analysis. Findings There was an overall mortality rate of 8.84 deaths per 1000 person-years of follow-up and causes of death were comparable with the literature. Increased exposure to episodes of opioid treatment longer than 7 days reduced the risk of mortality; there was no differential mortality among methadone versus buprenorphine participants. More dependent, heavier users of heroin at baseline had a lower risk of death, and also higher exposure to opioid treatment. Older participants randomized to buprenorphine treatment had significantly improved survival. Aboriginal or Torres Strait Islander participants had a higher risk of death. Conclusions Increased exposure to opioid maintenance treatment reduces the risk of death in opioid-dependent people. There was no differential reduction between buprenorphine and methadone. Previous studies suggesting differential effects may have been affected by biases in patient selection. [source]

Long-term prognostic value of B-type natriuretic peptide in cardiac and non-cardiac causes of acute dyspnoea

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 11 2007
M. Christ
Abstract Background, B-type natriuretic peptide (BNP) levels significantly predict increased risk of death in heart failure. The predictive role of BNP levels in patients with non-cardiac causes of acute dyspnoea presenting to the emergency department is not well characterized. Materials and methods, The B-type natriuretic peptide for Acute Shortness of Breath EvaLuation (BASEL) study enrolled consecutive patients with acute dyspnoea. Results, Cumulative mortality was 14·8%, 33·1% and 51·9% in 452 patients (age: 19,97 years; 58% male) within low (< 100 pg mL,1), intermediate (100,500 pg mL,1) and high (> 500 pg mL,1) BNP plasma levels at 18 months of follow-up. BNP classes (point estimate: 1·55, 95%CI: 1·19,2·03, P = 0·001) in addition to age, increased heart rate and diuretic use emerged as significant predictors for long-term mortality in multivariable Cox regression analyses. The BNP concentration alone had an area under the receiver operating characteristic curve of 0·71 (95%CI: 0·66,0·76; P < 0·001) for predicting 18 months mortality. BNP plasma levels independently predicted long-term risk of death in patients with non-cardiac (point estimate: 1·72, 95%CI: 1·16,2·56; P = 0·007) and with cardiac causes of acute dyspnoea (point estimate: 2·21, 95%CI: 1·34,3·64; P = 0·002). Conclusions, BNP levels are strong and independent predictors for long-term mortality in unselected dyspnoeic patients presenting to the emergency department independent from the cause of dyspnoea.

The importance of independent risk-factors for long-term mortality prediction after cardiac surgery

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 9 2006
I. K. Toumpoulis
Abstract Background, The purpose of the present study was to determine independent predictors for long-term mortality after cardiac surgery. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) was developed to score in-hospital mortality and recent studies have shown its ability to predict long-term mortality as well. We compared forecasts based on EuroSCORE with other models based on independent predictors. Methods, Medical records of patients with cardiac surgery who were discharged alive (n = 4852) were retrospectively reviewed. Their operative surgical risks were calculated according to EuroSCORE. Patients were randomly divided into two groups: training dataset (n = 3233) and validation dataset (n = 1619). Long-term survival data (mean follow-up 5·1 years) were obtained from the National Death Index. We compared four models: standard EuroSCORE (M1); logistic EuroSCORE (M2); M2 and other preoperative, intra-operative and post-operative selected variables (M3); and selected variables only (M4). M3 and M4 were determined with multivariable Cox regression analysis using the training dataset. Results, The estimated five-year survival rates of the quartiles in compared models in the validation dataset were: 94·5%, 87·8%, 77·1%, 64·9% for M1; 95·1%, 88·0%, 80·5%, 64·4% for M2; 93·4%, 89·4%, 80·8%, 64·1% for M3; and 95·8%, 90·9%, 81·0%, 59·9% for M4. In the four models, the odds of death in the highest-risk quartile was 8·4-, 8·5-, 9·4- and 15·6-fold higher, respectively, than the odds of death in the lowest-risk quartile (P < 0·0001 for all). Conclusions, EuroSCORE is a good predictor of long-term mortality after cardiac surgery. We developed and validated a model using selected preoperative, intra-operative and post-operative variables that has better discriminatory ability. [source]

Frailty predicts long-term mortality in elderly subjects with chronic heart failure

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 12 2005
F. Cacciatore
Abstract Background, The elderly are characterized by a high prevalence of chronic heart failure (CHF) and frailty, which is a complex interaction of physical, psychological and social impairment. This study aimed to examine the predictive role of frailty on long-term mortality in elderly subjects with CHF. Materials and methods, The study assessed long-term mortality after 12-year follow up in 120 subjects with CHF and 1139 subjects without CHF, selected in 1992, from a random sample of the elderly population in the Campania region of Italy. Frailty was assessed according to a ,Frailty Staging System'. Results, Subjects with CHF were prevalently female (60%) and older than 75 years (mean 75·9 ± 6·7); subjects without CHF were prevalently female (56·4%) and younger than 75 years (mean 74·0 ± 6·3). In subjects with and without CHF stratified into classes of frailty there was a statistically significant increase in age, comorbidity, disability and low social support, and a decrease in MMSE score. Moreover, death progressively increased more with frailty in subjects (70·0% to 94·4%, P < 0·03) than in those without (43·8.% to 88·3%, P < 0·0001) CHF. The Kaplan,Meier analysis shows that at 9 years the probability of survival progressively decreased as frailty increased (45·5% to 0%) in subjects with CHF and from 62·8% to 25·9% in subjects without CHF. The Cox regression analysis indicated that frailty is predictive of mortality in the multivariate model adjusted for several variables including sex and age in subjects with and without CHF. Moreover, the analysis showed that frailty is more predictive of mortality in elderly subjects with CHF when it was analyzed either as continuous (1·48 vs. 1·36) or as a dummy (3 vs. 1 = 1·62 vs. 1·24) variable. Conclusions, Thus mortality among elderly subjects with or without CHF increases with frailty. Moreover, frailty is more predictive of long-term mortality in elderly subjects with than in those without CHF. Hence, frailty represents a new independent variable for predicting long-term mortality in elderly subjects with CHF. [source]

A systematic review of the epidemiology of status epilepticus

EUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2004
R. F. M. Chin
Population-based data on the incidence, aetiology, and mortality associated with status epilepticus (SE) are required to develop preventative strategies for SE. Through a systematic review, we aimed to assess the methodological quality as well as similarities, and differences between available population based studies in order to arrive at conclusions on the epidemiology of SE. All population-based studies where primary outcome was incidence, aetiology or mortality of SE were identified through a systematic search and synthesized. Methodological quality of studies were independently rated by two examiners using a unique scoring system. Seven population-based projects on SE yielding nine published reports and five abstracts were reviewed. Quality scores were in the range of 19,34 with a possible maximum of 40 (kappa scores 0.67,1.0). The incidence of SE has a bimodal distribution with peaks in children aged less than a year and the elderly. Most SE were acute symptomatic. Short-term mortality was 7.6,22% and long-term mortality was 43%. Age and aetiology were the major determinants of mortality. There are few population-based studies on SE but most are of good quality. Most studies are primarily or exclusively based on adult populations. There is limited information on the association of ethnicity and socio-economic status and SE. [source]

The impact of HIV-1 co-infection on long-term mortality in patients with hepatitis C: a population-based cohort study

HIV MEDICINE, Issue 2 2009
LH Omland
Objective To investigate the impact of HIV co-infection on mortality in patients infected with hepatitis C virus (HCV). Methods From a nationwide Danish database of HCV-infected patients, we identified individuals diagnosed with HCV subsequent to an HIV diagnosis. For each co-infected patient, four control HCV patients without HIV were matched on age, gender and year of HCV diagnosis. Data on comorbidity, drug abuse, alcoholism and date of death were extracted from two healthcare databases. We constructed Kaplan,Meier curves and used Cox regression analyses to estimate mortality rate ratios (MRRs), controlling for comorbidity. Results We identified 483 HCV,HIV co-infected and 1932 HCV mono-infected patients, yielding 2192 and 9894 person-years of observation with 129 and 271 deaths, respectively. The 5-year probability of survival was 0.74 [95% confidence interval (CI) 0.69,0.80] for HCV,HIV co-infected patients and 0.87 (95% CI 0.85,0.89) for HCV mono-infected patients. Co-infection was associated with substantially increased mortality (MRR 2.1, 95% CI 1.7,2.6). However, prior to the first observed decrease in CD4 counts to below 300 cells/,L, HIV infection did not increase mortality in HCV-infected patients (MRR 0.9, 95% CI 0.5,1.50). Conclusions HIV infection has a substantial impact on mortality among HCV-infected individuals, mainly because of HIV-induced immunodeficiency. [source]

Outcome Predictors of Pneumonia in Elderly Patients: Importance of Functional Assessment

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2004
Olga H. Torres MD
Objectives: To evaluate the outcome of elderly patients with community-acquired pneumonia (CAP) seen at an acute-care hospital, analyzing the importance of CAP severity, functional status, comorbidity, and frailty. Design: Prospective observational study. Setting: Emergency department and geriatric medical day hospital of a university teaching hospital. Participants: Ninety-nine patients aged 65 and older seen for CAP over a 6-month recruitment period. Measurements: Clinical data were used to calculate Pneumonia Severity Index (PSI), Barthel Index (BI), Charlson Comorbidity Index, and Hospital Admission Risk Profile (HARP). Patients were then assessed 15 days later to determine functional decline and 30 days and 18 months later for mortality and readmission. Multiple logistic regression was used to analyze outcomes. Results: Functional decline was observed in 23% of the 93 survivors. Within the 30-day period, case-fatality rate was 6% and readmission rate 11%; 18-month rates were 24% and 59%, respectively. Higher BI was a protective factor for 30-day and 18-month mortality (odds ratio (OR)=0.96, 95% confidence interval (CI)=0.94,0.98 and OR=0.97, 95% CI=0.95,0.99, respectively; P<.01), and PSI was the only predictor for functional decline (OR=1.03, 95% CI=1.01,1.05; P=.01). Indices did not predict readmission. Analyses were repeated for the 74 inpatients and indicated similar results except for 18-month mortality, which HARP predicted (OR=1.73; 95% CI=1.16,2.57; P<.01). Conclusion: Functional status was an independent predictor for short- and long-term mortality in hospitalized patients whereas CAP severity predicted functional decline. Severity indices for CAP should possibly thus be adjusted in the elderly population, taking functional status assessment into account. [source]

Results of Treatment Methods in Cardiac Arrest Following Coronary Artery Bypass Grafting

JOURNAL OF CARDIAC SURGERY, Issue 3 2009
Mehmet R. Guney M.D.
We evaluated the short- and long-term consequences of these two methods and discussed the indications for re-revascularization. Methods: Between 1998 and 2004, a total of 148 CABG patients, who were complicated with cardiac arrest, were treated with emergency re-revascularization (n = 36, group R) and ICU procedures (n = 112, group ICU). Re-revascularizations are mostly blind operations depending on clinical/hemodynamic criteria. These are: no response to resuscitation, recurrent tachycardia/fibrillation, and severe hemodynamic instability after resuscitation. Re-angiography could only be performed in 3.3% of the patients. Event-free survival of the groups was calculated by the Kaplan-Meier method. Events are: death, recurrent angina, myocardial infarction, functional capacity, and reintervention. Results: Seventy percent of patients, who were complicated with cardiac arrest, had perioperative myocardial infarction (PMI). This rate was significantly higher in group R (p = 0.013). The major finding in group R was graft occlusion (91.6%). During in-hospital period, no difference was observed in mortality rates between the two groups. However, hemodynamic stabilization time (p = 0.012), duration of hospitalization (p = 0.00006), and mechanical support use (p = 0.003) significantly decreased by re-revascularization. During the mean 37.1 ± 25.1 months of follow-up period, long-term mortality (p = 0.03) and event-free survival (p = 0.029) rates were significantly in favor of group R. Conclusion: Better short- and long-term results were observed in the re-revascularization group. [source]

Abstract We investigated the short- and long-term effects of a controlled burn in Acacia drepanolobium woodland in Laikipia, Kenya in 1998. Fire temperatures averaged 250°C at ground level, with a maximum of over 500°C, but were rarely >100°C at 1.5 m above the ground or more. Nine months after the fire, virtually all A. drepanolobium trees had survived the fire. Some smaller trees were burnt to ground level, but most were only ,top-killed' and had coppiced. Taller trees suffered less damage than smaller trees. However, a 2003 satellite image suggested a dramatic reduction in A. drepanolobium canopy cover at the site. A survey of the site in 2006 revealed that the density of larger A. drepanolobium trees was nearly three times greater in adjacent control areas than in the old burn, with a lesser reduction in the density of smaller trees. These data suggest that short-term measures of postburn survivorship may be deceptive, and that an additional source of tree mortality (perhaps elephants) was concentrated on trees in burned areas, even many months after the burn, with long-term consequences for tree and ecosystem dynamics. Résumé Nous avons étudié les effets à court et à long terme d'un feu contrôlé dans la forêt àAcacia drepanolobium située à Laikipia, au Kenya, en 1998. La température du feu avoisinait les 250°C au niveau du sol, avec un maximum de 500°C, mais elle dépassait rarement les 100°C à 1,5 mètre au-dessus du sol et plus haut. Neuf mois après le feu, pratiquement tous les Acacia drepanolobium avaient survécu. Certains des arbres plus petits avaient brûlé jusqu'au ras du sol, mais chez la plupart, seule la partie aérienne avait brûlé et ils avaient fait des repousses. Les arbres plus grands avaient subi moins de dommages. Pourtant, une image satellite prise en 2003 a suggéré une réduction spectaculaire de la canopée d'A. drepanolobiumà cet endroit. Une étude du site réalisée en 2006 a révélé que la densité des plus grands A. drepanolobiumétait près de trois fois plus forte dans les zones de contrôle adjacentes que sur le site brûlé, où la densité des plus petits arbres était moins réduite. Ces données suggèrent que les mesures de la survie postincendie faites à court terme peuvent être trompeuses, et qu'une source supplémentaire de mortalité des arbres (peut-être des éléphants) s'est concentrée sur les arbres des zones brûlées, même plusieurs mois plus tard, avec des conséquences à long terme pour les arbres et la dynamique de l'écosystème.

Mortality in diabetic patients undergoing non-cardiac surgery: a 7-year follow-up study

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2009
M. KROLIKOWSKA
Background: The prognosis of diabetic patients after non-cardiac surgery remains controversial. This study was designed to compare the long-term mortality between diabetic and non-diabetic control patients undergoing non-cardiac surgery and to evaluate the possible risk factors. Methods: We investigated 274 consecutive diabetic patients and 282 non-diabetic control patients who underwent non-cardiac surgery within 1 year in a tertiary care hospital in Finland. The control group was matched for the same type of operations. Patients were followed for up to 7 years on average. The main outcome measure was mortality within 7 years. Results: Mortality both in the short-term postoperatively (,21 days) and in the long-term (up to 87 ½ months) was significantly higher in the diabetic patients compared with the non-diabetic group: 3.5 vs. 0% (P<0.05) and 37.2 vs. 15% (P<0.00001), respectively. The major causes of death among diabetic subjects were diseases of the cardiovascular system (56.8%) compared with non-diabetic patients (18.6%), P<0.0001. We found that diabetes mellitus per se is not a risk factor for post-operative mortality but a combination of variables had a significant effect on both short- and long-term mortality. Conclusion: Diabetic patients undergoing non-cardiac surgery had a significantly higher incidence of short-term post-operative and long-term mortality compared with non-diabetic subjects. We propose a model of predictors of death among diabetic individuals undergoing non-cardiac surgery within a 7-year follow-up. The majority of deaths were associated with cardiovascular diseases.

Postnatal corticosteroids in preterm infants: Systematic review of effects on mortality and motor function

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 2 2000
LW Doyle
Background: Postnatal corticosteroid therapy has been proved in randomized controlled trials to reduce ventilator dependence and the rate of chronic lung disease in preterm infants with few serious short-term side effects. However, there are other consequences that might follow postnatal corticosteroid therapy that are more important, including mortality or cerebral palsy. Objectives: To review the evidence from reported randomized controlled trials on the effects of postnatal corticosteroid on long-term mortality and motor dysfunction, including cerebral palsy. Methods: The methods involved a meta-analysis of reported randomized controlled trials, following guidelines of the Cochrane Collaboration, including calculation of event rate differences (ERD) and 95% confidence intervals (CI). Results: The mortality rate difference was non-significant both statistically and clinically (ERD , 0.1% favouring corticosteroids, 95% CI ,2.9% to 2.8%). There were no subgroups in which a beneficial effect of postnatal corticosteroids on survival could be demonstrated. The rate of motor dysfunction in survivors was significantly higher in survivors from the postnatal corticosteroid group (ERD 11.9% favouring controls, 95% CI 4.6% to 19.2%). The rate of survival, free of motor dysfunction, was significantly lower in the postnatal corticosteroid group (ERD 7.8% favouring controls, 95% CI 0.5% to 15.1%). Conclusions: Although postnatal corticosteroids have short-term benefits, they do not increase the survival rate, and they may cause motor dysfunction in survivors. A large-scale, placebo-controlled randomized trial, with survival free of sensorineural impairments and disabilities as the major endpoint, is urgently needed. [source]

Long-term prognosis for transplant-free survivors of paracetamol-induced acute liver failure

Aliment Pharmacol Ther 2010; 32: 894,900 Summary Background, The prognosis for transplant-free survivors of paracetamol-induced acute liver failure remains unknown. Aim, To examine whether paracetamol-induced acute liver failure increases long-term mortality. Methods, We followed up all transplant-free survivors of paracetamol-induced acute liver injury, hospitalized in a Danish national referral centre during 1984,2004. We compared age-specific mortality rates from 1 year post-discharge through 2008 between those in whom the liver injury led to an acute liver failure and those in whom it did not. Results, We included 641 patients. On average, age-specific mortality rates were slightly higher for the 101 patients whose paracetamol-induced liver injury had caused an acute liver failure (adjusted mortality rate ratio = 1.70, 95% CI 1.02,2.85), but the association was age-dependent, and no survivors of acute liver failure died of liver disease, whereas suicides were frequent in both groups. These observations speak against long-term effects of acute liver failure. More likely, the elevated mortality rate ratio resulted from incomplete adjustment for the greater prevalence of substance abuse among survivors of acute liver failure. Conclusions, Paracetamol-induced acute liver failure did not affect long-term mortality. Clinical follow-up may be justified by the cause of the liver failure, but not by the liver failure itself.

A model to predict survival at one month, one year, and five years after liver transplantation based on pretransplant clinical characteristics

LIVER TRANSPLANTATION, Issue 5 2003
Paul J. Thuluvath MD
Reliable models that could predict outcome of liver transplantation (LT) may guide physicians to advise their patients of immediate and late survival chances and may help them to optimize organ use. The objective of this study was to develop user-friendly models to predict short and long-term mortality after LT in adults based on pre-LT recipient characteristics. The United Network for Organ Sharing (UNOS) transplant registry (n = 38,876) from 1987 to 2001 was used to develop and validate the model. Two thirds of patients were randomized to develop the model (the modeling group), and the remaining third was randomized to cross-validate (the cross-validation group) it. Three separate models, using multivariate logistic regression analysis, were created and validated to predict survival at 1 month, 1 year, and 5 years. Using the total severity scores of patients in the modeling group, a predictive model then was created, and the predicted probability of death as a function of total score then was compared in the cross-validation group. The independent variables that were found to be very significant for 1 month and 1 year survival were age, body mass index (BMI), UNOS status 1, etiology, serum bilirubin (for 1 month and 1 year only), creatinine, and race (only for 5 years). The actual deaths in the cross-validation group followed very closely the predicted survival graph. The chi-squared goodness-of-fit test confirmed that the model could predict mortality reliably at 1 month, 1 year, and 5 years. We have developed and validated user-friendly models that could reliably predict short-term and long-term survival after LT. [source]

Early detection of acute kidney injury: Emerging new biomarkers (Review Article)

NEPHROLOGY, Issue 2 2008
ZOLTAN H ENDRE
SUMMARY: Acute kidney injury (AKI) has recently become the preferred term to describe the syndrome of acute renal failure (ARF) with ,failure' or ,ARF' restricted to patients who have AKI and need renal replacement therapy.1 This allows capture of the broader clinical spectrum of modest reductions in creatinine, which are themselves known to be associated with major increases in both short- and long-term mortality risk.2,5 It is hoped that this change in nomenclature will facilitate an expansion of our understanding of the underlying pathophysiology and also facilitate definitions of AKI, which allow comparisons among clinical trials of patients with similar duration and severity of illness. This review will cover the need for early detection of AKI and the role of urinary and plasma biomarkers, including enzymuria. The primary message is that use of existing criteria to diagnose AKI, namely elevation of the serum creatinine with or without oliguria, results in identification that is too late to allow successful intervention. New biomarkers are essential to change the dire prognosis of this common condition. [source]

Weight loss causes increased mortality: pros

OBESITY REVIEWS, Issue 1 2003
T. 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]

Neurological mortality among U.S. veterans of the Persian Gulf War: 13-year follow-up

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 9 2009
Shannon K. Barth MPH
Abstract Background This study focuses on long-term mortality, specifically brain cancer, amyotrophic lateral sclerosis (ALS), Parkinson's disease, and multiple sclerosis (MS) of 621,902 veterans who served in the 1990,1991 Persian Gulf War (GW), and 746,248 non-GW veterans. Methods Follow-up began with the date the veteran left the GW theater or May 1, 1991 and ended with the date of death or December 31, 2004. Cox proportional hazard models were used for analyses. Results Adjusted mortality rate ratios (aRR) of GW veterans compared to non-GW veterans were not statistically significant for brain cancer (aRR,=,0.90, 95% confidence interval (CI): 0.73, 1.11), MS (aRR,=,0.61, 95% CI: 0.23, 1.63), Parkinson's disease (aRR,=,0.71, 95% CI: 0.17, 2.99), or ALS (aRR,=,0.96, 95% CI: 0.56, 1.62). GW veterans potentially exposed to nerve agents for 2 or more days and GW veterans exposed to oil well fire smoke were at increased risk for brain cancer mortality (aRR,=,2.71, 95% CI: 1.25, 5.87; aRR,=,1.81, 95% CI: 1.00, 3.27; respectively). Conclusions The risk of death due to ALS, MS, Parkinson's disease, and brain cancer was not associated with 1991 GW service in general. However, GW veterans potentially exposed to nerve agents at Khamisiyah, Iraq, and to oil well fire smoke had an increased risk of mortality due to brain cancer. Am. J. Ind.

Evolution of Causes and Risk Factors for Mortality Post-Liver Transplant: Results of the NIDDK Long-Term Follow-Up Study

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2010
K. D. S. Watt
Although mortality rates following liver transplantation (LT) are well described, there is a lack of detailed, prospective studies determining patterns of and risk factors for long-term mortality. We analyzed the multicenter, prospectively obtained The National Institute of Diabetes and Digestive and Kidney Diseases LT Database of 798 transplant recipients from 1990 to 1994 (follow-up 2003). Overall, 327 recipients died. Causes of death >1 year: 28% hepatic, 22% malignancy, 11% cardiovascular, 9% infection, 6% renal failure. Renal-related death increased dramatically over time. Risk factors for death >1 year (univariate): male gender, age/decade, pre-LT diabetes, post-LT diabetes, post-LT hypertension, post-LT renal insufficiency, retransplantation >1 year, pre-LT malignancy, alcoholic disease (ALD) and metabolic liver disease, with similar risks noted for death >5 years. Hepatitis C, retransplantation, post-LT diabetes, hypertension and renal insufficiency were significant risk factors for liver-related death. Cardiac deaths associated with age, male gender, ALD, cryptogenic disease, pre-LT hypertension and post-LT renal insufficiency. In summary, the leading causes of late deaths after transplant were graft failure, malignancy, cardiovascular disease and renal failure. Older age, diabetes and renal insufficiency identified patients at highest risk of poor survival overall. Diligent management of modifiable post-LT factors including diabetes, hypertension and renal insufficiency may impact long-term mortality. [source]
