    Background/purpose In-hospital mortality rate of acute ischemic stroke patients remains between 3% and 18%. For improving the quality of stroke care, we investigated the factors that contribute to the risk of in-hospital mortality in acute ischemic stroke patients. Materials and methods Between January 1, 2007, and December 31, 2011, 2,556 acute ischemic stroke patients admitted to a stroke unit were included in this study. Factors such as demographic characteristics, clinical characteristics, comorbidities, and complications related to in-hospital mortality were assessed. Results Of the 2,556 ischemic stroke patients, 157 received thrombolytic therapy. Eighty of the 2,556 patients (3.1%) died during hospitalization. Of the 157 patients who received thrombolytic therapy, 14 (8.9%) died during hospitalization. History of atrial fibrillation (AF, P<0.01) and stroke severity (P<0.01) were independent risk factors of in-hospital mortality. AF, stroke severity, cardioembolism stroke, and diabetes mellitus were independent risk factors of hemorrhagic transformation. Herniation and sepsis were the most common complications of stroke that were attributed to in-hospital mortality. Approximately 70% of in-hospital mortality was related to stroke severity (total middle cerebral artery occlusion with herniation, basilar artery occlusion, and hemorrhagic transformation). The other 30% of in-hospital mortality was related to sepsis, heart disease, and other complications. Conclusion AF is associated with higher in-hospital mortality rate than in patients without AF. For improving outcome of stroke patients, we also need to focus to reduce serious neurological or medical complications. PMID:27418830

    Abstract The purpose of this article is to evaluate the American Society of Anesthesiologists Physical Status (ASA PS) and the Charlson comorbidity index (CCI) for the prediction of postoperative mortality. The ASA PS has been suggested to be equally good as the CCI in predicting postoperative outcome. However, these scores have never been compared in a broad surgical population. We conducted a retrospective cohort study in a German tertiary care university hospital. Predictive accuracy was compared using the area under the receiver-operating characteristic curves (AUROC). In a post hoc approach, a regression model was fitted and cross-validated to estimate the association of comorbidities and intraoperative factors with mortality. This model was used to improve prediction by recalibrating the CCI for surgical patients (sCCIs) and constructing a new surgical mortality score (SMS). The data of 182,886 patients with surgical interventions were analyzed. The CCI was superior to the ASA PS in predicting postoperative mortality (AUROCCCI 0.865 vs AUROCASAPS 0.833, P < 0.001). Predictive quality further improved after recalibration of the sCCI and construction of the new SMS (AUROCSMS 0.928 vs AUROCsCCI 0.896, P < 0.001). The SMS predicted postoperative mortality especially well in patients never admitted to an intensive care unit. The newly constructed SMS provides a good estimate of patient's risk of death after surgery. It is capable of identifying those patients at especially high risk and may help reduce postoperative mortality. PMID:25715258

    The present study was undertaken at a rural medical institute in India to analyse the trends in maternal mortality due to sepsis and the factors associated with change, if any. During the study period of 20 years, a total of 37,155 women delivered, 192 deaths occurred and forty deaths (20.83%) were due to sepsis and it's sequlae. It was revealed that there is a definite decrease in the proportion of deaths due to sepsis, to 10% in the last five years from 35% in earlier years. The change seems to be due to the advocacy of clean deliveries and reduction in case fatality because of alterations in medication and earlier surgical intervention. However the percentage contribution of septic abortion has remained the same. Septic abortion continues to exist inspite of all the current laws and discussion about the availability of a liberal law, which permits abortion almost on request. Most of the women who had died due to septic abortion were married (65%). Deaths due to septic abortion, are persisting even in married women and it is a matter of concern for health providers, policy makers and governments. PMID:15814392

  4. Independent influence of negative blood cultures and bloodstream infections on in-hospital mortality

    2014-01-01

    Background The independent influence of blood culture testing and bloodstream infection (BSI) on hospital mortality is unclear. Methods We included all adults treated in non-psychiatric services at our hospital between 2004 and 2011. We identified all blood cultures and their results to determine the independent association of blood culture testing and BSI on death in hospital using proportional hazards modeling that adjusted for important covariates. Results Of 297 070 hospitalizations, 48 423 had negative blood cultures and 5274 had BSI. 12 529 (4.2%) died in hospital. Compared to those without blood cultures, culture-negative patients and those with BSI were sicker. Culture-negative patients had a significantly increased risk of death in hospital (adjusted hazard ratio [HR] ranging between 3.1 and 4.4 depending on admission urgency, extent of comorbidities, and whether the blood culture was taken in the intensive care unit). Patients with BSI had a significantly increased risk of death (adj-HR ranging between 3.8 and 24.3] that was significantly higher when BSI was: diagnosed within the first hospital day; polymicrobial; in patients who were exposed to immunosuppressants or were neutropenic; or due to Clostridial and Candidal organisms. Death risk in culture negative and bloodstream infection patients decreased significantly with time. Conclusions Risk of death in hospital is independently increased both in patients with negative blood cultures and further in those with bloodstream infection. Death risk associated with bloodstream infections varied by the patient’s immune status and the causative microorganism. PMID:24444097

    Studies have demonstrated an increasing Clostridium difficile infection (CDI) incidence in hospitals and the community, with increasing morbidity and mortality. In this study, we analyzed data from the National Hospital Discharge Survey (NHDS) to evaluate CDI epidemiology, outcomes, and predictors of mortality in hospitalized adults. We identified cases of CDI (and associated comorbid conditions) from NHDS data from 2005 through 2009 using ICD-9 codes. Weighted univariate and multivariate analyses were performed to ascertain CDI incidence, associations between CDI and outcomes [length of stay (LOS), colectomy, all-cause in-hospital mortality, and discharge to a care facility], and predictors of all-cause in-hospital mortality. Of an estimated 162 million adult inpatients, 1.26 million (0.8 %) had CDI. The overall CDI incidence is 77.8/10,000 hospitalizations, with no statistically significant change over the study period. On multivariate analysis, after adjusting for age, gender, and comorbid conditions, CDI is an independent predictor of longer LOS (mean difference, 2.35 days), all-cause mortality [odds ratio (OR) 1.45], colectomy (OR 1.41), and discharge to a care facility (OR 2.12) (all P < 0.001). Elderly patients have a higher CDI incidence and worse outcomes than younger adults. The strongest predictors of all-cause mortality in patients with CDI include age 65 years or older, colectomy, and coagulation abnormalities. Despite stable CDI incidence and advances in management, CDI is associated with increased LOS, colectomy, all-cause in-hospital mortality, and discharge to a care facility in hospitalized, especially elderly, adults. Age older than 65 years should be added to the severity criteria for CDI. PMID:26694494

    AIM: To determine the predictors of 50 d in-hospital mortality in decompensated cirrhosis patients with spontaneous bacterial peritonitis (SBP). METHODS: Two hundred and eighteen patients admitted to an intensive care unit in a tertiary care hospital between June 2013 and June 2014 with the diagnosis of SBP (during hospitalization) and cirrhosis were retrospectively analysed. SBP was diagnosed by abdominal paracentesis in the presence of polymorphonuclear cell count ≥ 250 cells/mm3 in the peritoneal fluid. Student’s t test, multivariate logistic regression, cox proportional hazard ratio (HR), receiver operating characteristics (ROC) curves and Kaplan-Meier survival analysis were utilized for statistical analysis. Predictive abilities of several variables identified by multivariate analysis were compared using the area under ROC curve. P < 0.05 were considered statistical significant. RESULTS: The 50 d in-hospital mortality rate attributable to SBP is 43.11% (n = 94). Median survival duration for those who died was 9 d. In univariate analysis acute kidney injury (AKI), hepatic encephalopathy, septic shock, serum bilirubin, international normalized ratio, aspartate transaminase, and model for end-stage liver disease - sodium (MELD-Na) were significantly associated with in - hospital mortality in patients with SBP (P ≤ 0.001). Multivariate cox proportional regression analysis showed AKI (HR = 2.16, 95%CI: 1.36-3.42, P = 0.001) septic shock (HR = 1.73, 95%CI: 1.05-2.83, P = 0.029) MELD-Na (HR = 1.06, 95%CI: 1.02-1.09, P ≤ 0.001) was significantly associated with 50 d in-hospital mortality. The prognostic accuracy for AKI, MELD-Na and septic shock was 77%, 74% and 71% respectively associated with 50 d in-hospital mortality in SBP patients. CONCLUSION: AKI, MELD-Na and septic shock were predictors of 50 d in-hospital mortality in decompensated cirrhosis patients with SBP. PMID:27134704

    Background Takotsubo cardiomyopathy (TTC) is characterized by reversible left ventricular dysfunction, frequently precipitated by a stressful event. Despite the favorable course and good long-term prognosis, a variety of complications may occur in the acute phase of the disease. The aim of this study was to evaluate the in-hospital and long-term outcomes of a cohort of TTC patients. Methods Fifty-five patients (mean age 68.1±12 years) were prospectively followed for a mean of 69.6±32.2 months (64,635 days). In-hospital (death, heart failure, arrhythmias) and long-term events (death and recurrences) were recorded. Results Patients were predominantly women (87.3%) who experienced a recent stressful event (emotional or physical) and were admitted to hospital for chest pain. Eleven patients (20%) had a diagnosis of depressive disorder, and arterial hypertension was the most frequent cardiovascular risk factor. The ECG revealed ST-segment elevation in 43.6% of patients. At angiography, seven cases (12.7%) had at least one significant (≥50%) coronary artery stenosis and four patients (7.3%) had myocardial bridging of the left anterior descending artery. During hospitalization, three patients died (one from cardiac causes) and cardiovascular complications occurred in 12 patients. During follow-up, five patients died (none from cardiac causes), six patients had recurrences within the first year. Two patients had two recurrences: one after 114 days, triggered by an asthma attack as the first event, and the other after 1,850 days. Conclusions In TTC patients, in-hospital and long-term mortality is primarily due to non-cardiovascular causes. Recurrences are not infrequent and coronary artery disease is not an uncommon finding.

    Few studies have evaluated the risk factors for in-hospital mortality in critically ill surgical patients who have undergone emergency gastrointestinal (GI) surgery. The aim of this study was to identify the risk factors associated with in-hospital mortality in critically ill surgical patients after emergency GI surgery.The medical records of 362 critically ill surgical patients who underwent emergency GI surgery, admitted to intensive care unit between January 2007 and December 2011, were reviewed retrospectively. Perioperative biochemical and clinical parameters of survivors and nonsurvivors were compared. Logistic regression multivariate analysis was performed to identify the independent risk factors of mortality.The in-hospital mortality rate was 15.2% (55 patients). Multivariate analyses revealed cancer-related perforation (odds ratio [OR] 16.671, 95% confidence interval [CI] 2.629-105.721, P = 0.003), preoperative anemia (hemoglobin <10 g/dL; OR 6.976, 95% CI 1.376-35.360, P = 0.019), and preoperative hypoalbuminemia (albumin <2.7 g/dL; OR 9.954, 95% CI 1.603-61.811, P = 0.014) were independent risk factors of in-hospital mortality after emergency GI surgery.The findings of this study suggest that in critically ill patients undergoing emergency GI surgery, cancer-related peritonitis, preoperative anemia, and preoperative hypoalbuminemia are associated with in-hospital mortality. Recognizing risk factors at an early stage could aid risk stratification and the provision of optimal perioperative care. PMID:27583863

    Purpose Redo cardiac operations represent one of the main challenges in heart surgery. The purpose of the study was to analyze the predictors of in-hospital mortality in patients undergoing reoperative cardiac surgery by a single surgical team. Methods A total of 1367 patients underwent cardiac surgical procedures and prospectively entered into a computerized database. Patients were divided into 2 groups based on the reoperative cardiac surgery (n = 109) and control group (n = 1258). Uni- and multivariate logistic regression analysis were performed to evaluate the possible predictors of hospital mortality. Results Mean age was 56 ± 13, and 46% were female in redo group. In-hospital mortality was 4.6 vs. 2.2%, p = 0.11. EuroSCORE (6 vs. 3; p < 0.01), cardiopulmonary bypass time (90 vs. 71 min; p < 0.01), postoperative bleeding (450 vs. 350 ml; p < 0.01), postoperative atrial fibrillation (AF) (29 vs. 16%; p < 0.01), and inotropic support (58 vs. 31%; p = 0.001) were significantly different. These variables were entered into uni- and multivariate regression analysis. Postoperative AF (OR1.76, p = 0.007) and EuroSCORE (OR 1.42, p < 0.01) were significant risk factors predicting hospital mortality. Conclusions Reoperative cardiac surgery can be performed under similar risks as primary operations. Postoperative AF and EuroSCORE are predictors of in-hospital mortality for redo cases.

  11. Deficiency of ADAMTS-13 in pediatric patients with severe sepsis and impact on in-hospital mortality

    PubMed Central

    2013-01-01

    Background The enzyme involved in regulating the size of vWF (von Willebrand factor) in plasma is ADAMTS-13 (A disintegrin and metalloprotease with thrombospondin type-1 motives). Deficient proteolysis of ULvWF (ultra large von Willebrand factor) due to reduced ADAMTS-13 activity results in disseminated platelet-rich thrombi in the microcirculation characteristic of thrombotic thrombocytopenic purpura. Reduced ADAMTS-13 has also been observed in severe sepsis and is associated with poor survival. We conducted this study to detect ADAMTS-13 deficiency and its impact on in-hospital mortality in pediatric patients with severe sepsis. Methods Pediatric patients diagnosed with severe sepsis were recruited for the study. Baseline clinical characteristics were noted. ADAMTS-13 antigen levels were assayed by ELISA. According to ADAMTS-13 levels, patients were grouped as deficient and non-deficient. Comparison was done with regard to some clinical and biological characteristics and in-hospital mortality between the two groups. Results A total of 80 patients were enrolled in the study. The median age of the patients was 3.1 years (Range: 0.1-15 years). ADAMTS-13 deficiency with levels less than 350 ng/dl was found in 65% patients. In patients with ADAMTS-13 deficiency, 75.6% had low platelets of less than 150 × 109/L. In-hospital mortality was 42.3% and 35.7% in ADAMTS-13 deficient and non-deficient group, respectively. Conclusion Majority of the pediatric patients admitted to hospital with severe sepsis exhibit ADAMTS-13 deficiency. ADAMTS-13 deficiency might play a role in sepsis-induced thrombocytopenia. More studies are needed to evaluate the role of ADAMTS-13 deficiency on in-hospital mortality. PMID:23537039

    Background/Aim: The recent years have witnessed an increase in number of people harboring chronic liver diseases. Gastroesophageal variceal bleeding occurs in 30% of patients with cirrhosis, and accounts for 80%-90% of bleeding episodes. We aimed to assess the in-hospital mortality rate among subjects presenting with variceal gastrointestinal bleeding and (2) to investigate the predictors of mortality rate among subjects presenting with variceal gastrointestinal bleeding. Patients and Methods: This retrospective study was conducted from treatment records of 317 subjects who presented with variceal upper gastrointestinal bleeding to Government Medical College, Patiala, between June 1, 2010, and May 30, 2014. The data thus obtained was compiled using a preset proforma, and the details analyzed using SPSSv20. Results: Cirrhosis accounted for 308 (97.16%) subjects with bleeding varices, with extrahepatic portal vein obstruction 9 (2.84%) completing the tally. Sixty-three (19.87%) subjects succumbed to death during hospital stay. Linear logistic regression revealed independent predictors for in-hospital mortality, including higher age (P = 0.000), Child-Pugh Class (P = 0.002), altered sensorium (P = 0.037), rebleeding within 24 h of admission (P = 0.000), low hemoglobin level (P = 0.023), and serum bilirubin (P = 0.002). Conclusion: Higher age, low hemoglobin, higher Child-Pugh Class, rebleeding within 24 h of admission, higher serum bilirubin, and lower systolic blood pressure are the independent predictors of in-hospital mortality among subjects presenting with variceal gastrointestinal bleeding.

    Introduction Comprehensive stroke centers (CSCs) accept transferred patients from referring hospitals in a given regional area. The transfer process itself has not been studied as a potential factor that may impact outcome. We compared in-hospital mortality and severe disability or death at CSCs between transferred and directly admitted intracerebral hemorrhage (ICH) patients of matched severity. Materials and Methods We retrospectively reviewed all primary ICH patients from a prospectively-collected stroke registry and electronic medical records, at two tertiary care sites. Patients meeting inclusion criteria were divided into two groups: patients transferred in for a higher level of care and direct presenters. We used propensity scores (PS) to match 175 transfer patients to 175 direct presenters. These patients were taken from a pool of 530 eligible patients, 291 (54.9%) of whom were transferred in for a higher level of care. Severe disability or death was defined as a modified Rankin Scale (mRS) sore of 4–6. Mortality and morbidity were compared between the 2 groups using Pearson chi-squared test and Student t test. We fit logistic regression models to estimate odds ratios (OR) and 95% confidence intervals (CI) for association between transfer status and in-hospital mortality and severe disability or death in full and PS-matched patients. Results There were no significant differences in the PS-matched transfer and direct presentation groups. Patients transferred to a regional center were not at higher odds of in-hospital mortality (OR: 0.93, 95% CI: 0.50–1.71) and severe disability or death (OR: 0.77, 95% CI: 0.39–1.50), than direct presenters, even after adjustment for PS, age, baseline NIHSS score, and glucose on admission. Conclusion Our observation suggests that transfer patients of similar disease burden are not at higher risk of in-hospital mortality than direct presenters. PMID:27467594

    2011-01-01

    Background Infectious diseases are a common cause of increased morbidity and mortality in elderly patients. Bacteraemia in the elderly is a difficult diagnosis and a therapeutic challenge due to age-related vicissitudes and to their comorbidities. The main purpose of the study was to assess independent risk factors for in-hospital mortality among the elderly with bacteraemia admitted to an Internal Medicine Ward. Methods Overall, a cohort of 135 patients, 65 years of age and older, with bacteraemia were retrospectively studied. Data related to demographic information, comorbidities, clinical parameters on admission, source and type of infection, microorganism isolated in the blood culture, laboratory data and empirical antibiotic treatment was recorded from each patient. Multivariate logistic regression was performed to identify independent predictors of all-cause in-hospital mortality. Results Of these 135 patients, 45.9% were women. The most common infections in this group of patients were urinary tract infections (46.7%). The main microorganisms isolated in the blood cultures were Escherichia coli (14.9%), Methicillin-resistant Staphylococcus aureus (MRSA) (12.0%), non-MRSA (11.4%), Klebsiella pneumoniae (9.1%) and Enterococcus faecalis (8.0%). The in-hospital mortality was 22.2%. Independent prognostic factors associated with in-hospital mortality were age ≥ 85 years, chronic renal disease, bacteraemia of unknown focus and cognitive impairment at admission (OR, 2.812 [95% CI, 1.039-7.611; p = 0.042]; OR, 6.179 [95% CI, 1.840-20.748; p = 0.003]; OR, 8.673 [95% CI, 1.557-48.311; p = 0.014] and OR, 3.621 [95% CI, 1.226-10.695; p = 0.020], respectively). By multivariate analysis appropriate antibiotic therapy was not associated with lower odds of mortality. Conclusion Bacteraemia in the elderly has a high mortality rate. There are no set of signs or clinical features that can predict bacteraemia in the elderly. However, older age (≥ 85 years), chronic renal

    Hyponatremia is known to be a poor prognostic factor in patients hospitalized with heart failure (HF), however not well studied in Japan. The aims of this study were to characterize hyponatremic hospitalized patients with HF and to clarify the relations between hyponatremia and detailed in-hospital outcomes in Japan. Among 4,837 hospitalized patients with HF enrolled in the Acute Decompensated Heart Failure Syndromes (ATTEND) registry, patient characteristics and in-hospital mortality in those with hyponatremia were examined. Hyponatremia (sodium <135 mEq/L) was observed in 11.6% of patients. Patients with hyponatremia were of similar age, included fewer men, and had a higher proportion of previous hospitalizations for HF compared to those with normonatremia. On admission, lower heart rates and blood pressures and higher brain natriuretic peptide levels were observed in patients with hyponatremia. During hospitalization, inotrope levels and mechanical device use were significantly higher in patients with hyponatremia. Rates of all-cause and cardiac death were significantly higher in patients with hyponatremia, 15.0% and 11.4%, respectively, compared to 5.3% and 3.6%, respectively, in those with normonatremia. In hyponatremic hospitalized patients with HF, cardiac death accounted for 76.2% of all-cause death. In conclusion, the present study demonstrates that in Japan hyponatremia in patients hospitalized with HF is relatively common and is associated with a very high in-hospital mortality. PMID:23312128

    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 Previous studies have demonstrated that the rising mortality due to mesothelioma and asbestosis can be predicted from historic asbestos usage. Mortality due to idiopathic pulmonary fibrosis (IPF) is also rising, without any apparent explanation. Aims To compare mortality due to these conditions and examine the relationship between mortality and national asbestos imports. Methods Mortality data for IPF and asbestosis in England and Wales were available from the Office for National Statistics. Data for mesothelioma deaths in England and Wales and historic UK asbestos import data were available from the Health & Safety Executive. The numbers of annual deaths due to each condition were plotted separately by gender, against UK asbestos imports 48 years earlier. Linear regression models were constructed. Results For mesothelioma and IPF, there was a significant linear relationship between the number of male and female deaths each year and historic UK asbestos imports. For asbestosis mortality, a similar relationship was found for male but not female deaths. The annual numbers of deaths due to asbestosis in both sexes were lower than for IPF and mesothelioma. Conclusions The strength of the association between IPF mortality and historic asbestos imports was similar to that seen in an established asbestos-related disease, i.e. mesothelioma. This finding could in part be explained by diagnostic difficulties in separating asbestosis from IPF and highlights the need for a more accurate method of assessing lifetime occupational asbestos exposure.

    Most firearm-related injuries are nonfatal and require hospitalization. Using data on 3,257,720 hospitalizations from the National Hospital Discharge Survey (2000-2010), we determined overall and cause-, gender-, and race-specific trends in firearm-related hospitalization (FRH) and determinants of in-hospital firearm mortality. Types of FRH evaluated, according to International Classification of Diseases, Ninth Revision, Clinical Modification, E-diagnostic codes, were accident (codes E922.0-E922.3, E922.8, and E922.9), assault (codes E965.0-E965.4), attempted suicide (codes E955.0-E955.4), legal intervention (code E970), undetermined intent (codes E985.0-E985.3), and war (code E991). A moderate reduction in FRH rates was observed from 2000 to 2011: from 62 FRHs per 100,000 hospitalizations to 57 per 100,000 (P-trend = 0.0016). The majority of FRHs were due to assault (P-trend = 0.19) or accident (P-trend = 0.32) and showed no significant reduction in rates over time, whereas rates for 14% of all FRHs-those due to attempted suicide (P-trend = 0.002) and undetermined intent (P-trend = 0.0029)-declined moderately. Moderate declines were observed among both blacks (from 213.1 FRHs per 100,000 hospitalizations to 164.4 per 100,000; P-trend = 0.049) and whites (from 38.4 FRHs per 100,000 hospitalizations to 32.2 per 100,000; P-trend = 0.031). The decline was significant only among men (effect size = 0.9, P-trend = 0.004). In conclusion, the reduction in FRH was driven by a reduction in self-inflicted and undetermined injuries. FRH rates were 6-fold greater among blacks than among whites and 14-fold greater in men than in women throughout the period. PMID:24148708

    Patients infected or colonized with carbapenem-resistant Klebsiella pneumoniae (CRKp) are often chronically and acutely ill, which results in substantial mortality unrelated to infection. Therefore, estimating excess mortality due to CRKp infections is challenging. The Consortium on Resistance against Carbapenems in K. pneumoniae (CRACKLE) is a prospective multicenter study. Here, patients in CRACKLE were evaluated at the time of their first CRKp bloodstream infection (BSI), pneumonia or urinary tract infection (UTI). A control cohort of patients with CRKp urinary colonization without CRKp infection was constructed. Excess hospital mortality was defined as mortality in cases after subtracting mortality in controls. In addition, the adjusted hazard ratios (aHR) for time-to-hospital-mortality at 30 days associated with infection compared with colonization were calculated in Cox proportional hazard models. In the study period, 260 patients with CRKp infections were included in the BSI (90 patients), pneumonia (49 patients) and UTI (121 patients) groups, who were compared with 223 controls. All-cause hospital mortality in controls was 12%. Excess hospital mortality was 27% in both patients with BSI and those with pneumonia. Excess hospital mortality was not observed in patients with UTI. In multivariable analyses, BSI and pneumonia compared with controls were associated with aHR of 2.59 (95% CI 1.52-4.50, p <0.001) and 3.44 (95% CI 1.80-6.48, p <0.001), respectively. In conclusion, in patients with CRKp infection, pneumonia is associated with the highest excess hospital mortality. Patients with BSI have slightly lower excess hospital mortality rates, whereas excess hospital mortality was not observed in hospitalized patients with UTI. PMID:26850824

    One of the main purposes of admission for anorexia nervosa is to manage acute medical conditions related to this condition. Factors associated with in-hospital mortality in anorexia nervosa remain unclear. This study describes the clinical features of anorexia nervosa patients requiring hospitalization in Japan. We analyzed the association between in-hospital mortality and body mass index upon admission using a currently available, nationwide hospital-based database. We identified 669 eligible patients with anorexia nervosa (BMI ≤ 16.5) from 229 hospitals between July and December, 2010. More than 90 % of the patients were female and 100 patients were admitted involuntarily. The average body mass index was 13.1, and the in-hospital mortality rate was 0.7 %. Five patients who died had a BMI under 11, indicating that patients with an extremely low BMI may be likely to die, despite admission. PMID:23929026

    Fisheries often exert selective pressures through elevated mortality on a nonrandom component of exploited stocks. Selective removal of individuals will alter the composition of a given population, with potential consequences for its size structure, stability and evolution. Gillnets are known to harvest fish according to size. It is not known, however, whether delayed mortality due to disentanglement from gillnets exerts selective pressures that reinforce or counteract harvest selection. We examined gillnet disentanglement in exploited populations of sockeye salmon (Oncorhynchus nerka) in Bristol Bay, Alaska, to characterize the length distribution of fish that disentangle from gillnets and determine whether nonretention mortality reinforces harvest selection and exerts common pressures according to sex and age. We also evaluated discrete spawning populations to determine whether nonretention affects populations with different morphologies in distinct ways. In aggregate, nonretention mortality in fish that disentangle from gillnets counters harvest selection but with different effects by sex and age. At the level of individual spawning populations, nonretention mortality may exert stabilizing, disruptive, or directional selection depending on the size distribution of a given population. Our analyses suggest nonretention mortality exerts significant selective pressures and should be explicitly included in analyses of fishery-induced selection. PMID:25567993

    In the 1970's and 1980's, there were large inter-village disparities in infant mortality due to congenital anomalies on Guam. A village-level analysis was conducted to determine if these disparities can be explained by behavioral (ie, median age of village females, village fertility ratio), structural (ie, population density, persons per household, single mother households per village, married females per village), and environmental (ie, living in a village where Agent Orange (AO) spraying was conducted) factors. Village-level data for live births and infant mortality due to congenital anomalies (1970–1989) was collected from Guam's Office of Vital Statistics. Data on median age of village females, village fertility ratio, population density, persons per household, single mother households, and married females were obtained from the 1980 US Census. Estimates of village-level AO use were provided through personal communications, and villages were dichotomized into AO and non-AO spray areas. Village location was classified by usual residence of the mother. Linear regression was used to determine associations between infant mortality due to congenital anomalies and the behavioral, structural, and environmental factors. The association between AO spray area and infant mortality due to congenital anomalies was statistically significant under univariable (B [95%CI] = 1.88 [0.64,3.11], P = .005) and multivariable conditions (B [95%CI] = 2.02 [0.08,3.96], P = .042). These results suggest that infants born to mothers whose usual residence was in an AO spray area on Guam are at an increased risk of mortality due to congenital anomalies. Further studies using individual-level data are needed to validate these results. PMID:26668770

    Objective Obesity is associated with increased risk of diabetes, hypertension and cardiovascular mortality. Several studies have reported increased length of hospital stay and complications; however, there are also reports of obesity having a protective effect on health, a phenomenon coined the ‘obesity paradox’. We aimed to investigate the impact of overweight and obesity on complications and mortality in hospitalized patients with hyperglycemia and diabetes. Research design and methods This retrospective analysis was conducted on 29 623 patients admitted to two academic hospitals in Atlanta, Georgia, between January 2012 and December 2013. Patients were subdivided by body mass index into underweight (body mass index <18.5 kg/m2), normal weight (18.5–24.9 kg/m2), overweight (25–29.9 kg/m2) and obese (>30 kg/m2). Hyperglycemia was defined as a blood glucose >10 mmol/L during hospitalization. Hospital complications included a composite of pneumonia, acute myocardial infarction, respiratory failure, acute kidney injury, bacteremia and death. Results A total of 4.2% were underweight, 29.6% had normal weight, 30.2% were overweight, and 36% were obese. 27.2% of patients had diabetes and 72.8% did not have diabetes (of which 75% had hyperglycemia and 25% had normoglycemia during hospitalization). A J-shaped curve with higher rates of complications was observed in underweight patients in all glycemic groups; however, there was no significant difference in the rate of complications among normal weight, overweight, or obese patients, with and without diabetes or hyperglycemia. Conclusions Underweight is an independent predictor for hospital complications. In contrast, increasing body mass index was not associated with higher morbidity or mortality, regardless of glycemic status. There was no evidence of an obesity paradox among inpatients with diabetes and hyperglycemia. PMID:27486518

    Background The prognostic factors of in-hospital mortality in all comers and unselected patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) have not been well established. Objective To identify the predictive factors of in-hospital mortality in patients with STEMI undergoing primary PCI in a tertiary heart centre. Methods Between January 2008 and December 2011, all patients with STEMI undergoing primary PCI were retrospectively included in this study. Baseline characteristics and angiographic data were reviewed and recorded. The study endpoint was all-cause in-hospital mortality. Results Of the 541 patients included in the study, 63 (11.6%) died during hospitalisation. Cardiogenic shock at admission was recorded in 301 patients (55.6%) and 424 patients (78%) had multivessel disease. Median door-to-device time was 65 min. After adjustment for baseline variables, the factors associated with in-hospital mortality included age >60 years (OR 2.98, 95% CI 1.17 to 7.05; p=0.01), left ventricular ejection fraction <40% (OR 2.53, 95% CI 1.20 to 5.36; p=0.02), and final TIMI flow grade 0/1 (OR 20.55, 95% CI 3.49 to 120.94; p=0.001). Conclusions Age, left ventricular function and final TIMI flow are significant predictors of adverse outcomes in unselected patients with STEMI undergoing primary PCI. PMID:27347008

    Objective Hyperglycemia on admission and during hospital stay is a well-established predictor of short-term and long-term mortality in patients with acute myocardial infarction. Our study investigated the impact of blood glucose levels on admission and in-hospital hyperglycemia on the morbidity and mortality of Libyan patients admitted with acute coronary syndromes (acute myocardial infarction and unstable angina). Methods In this retrospective study, the records of patients admitted with acute coronary syndrome to The 7th Of October Hospital, Benghazi, Libya, between January 2011 and December 2011 were reviewed. The level of blood glucose on admission, and the average blood glucose during the hospital stay were recorded to determine their effects on in-hospital complications (e.g. cardiogenic shock, acute heart failure, arrhythmias, and/or heart block) and mortality. Results During the study period, 121 patients with diabetes were admitted with acute coronary syndrome. The mortality rate in patients with diabetes and acute coronary syndrome was 12.4%. Patients with a mean glucose level greater than 200mg/dL had a higher in-hospital mortality and a higher rate of complications than those with a mean glucose level ≤200mg/dL (27.5% vs. 2.6%, p<0.001 and 19.7% vs. 45.5%, p=0.004, respectively). There was no difference in in-hospital mortality between patients with a glucose level at admission ≤140mg/dL and those admitted with a glucose level >140mg/dL (6.9% vs. 14.3%; p=0.295), but the rate of complications was higher in the latter group (13.8% vs. 34.1%; p=0.036). Patients with admission glucose levels >140mg/dL also had a higher rate of complications at presentation (26.4% vs. 6.9%; p=0.027). Conclusion In patients with diabetes and acute coronary syndrome, hyperglycemia during hospitalization predicted a worse outcome in terms of the rates of in-hospital complications and in-hospital mortality. Hyperglycemia at the time of admission was also associated with

    Background and objectives Inhaled corticosteroids (ICS) and long-acting inhaled bronchodilators (IBD) are beneficial for the management of COPD. Although ICS has been reported to increase the risk of pneumonia in patients with COPD, it remains controversial whether it influences mortality. Using a Japanese national database, we examined the association between preadmission ICS therapy and in-hospital mortality from pneumonia in patients with COPD. Methods We retrospectively collected data from 1,165 hospitals in Japan on patients with COPD who received outpatient inhalation therapy and were admitted with pneumonia. Patients were categorized into those who received ICS with IBD and those who received IBD alone. We performed multivariate logistic regression analysis to examine the association between outpatient ICS therapy and in-hospital mortality, adjusting for the patients’ backgrounds. Results Of the 7,033 eligible patients, the IBD alone group (n=3,331) was more likely to be older, have lower body mass index, poorer general conditions, and more severe pneumonia than the ICS with IBD group (n=3,702). In-hospital mortality was 13.2% and 8.1% in the IBD alone and the ICS with IBD groups, respectively. After adjustment for patients’ backgrounds, the ICS with IBD group had significantly lower mortality than the IBD alone group (adjusted odds ratio, 0.80; 95% confidence interval, 0.68–0.94). Higher mortality was associated with older age, being male, lower body mass index, poorer general status, and more severe pneumonia. Conclusion Outpatient inhaled ICS and IBD therapy was significantly associated with lower mortality from pneumonia in patients with COPD than treatment with IBD alone. PMID:27382276

    Abstract Aspartate aminotransferase to platelet ratio index (APRI) has originally been considered as a noninvasive marker for detecting hepatic fibrosis in patients with chronic hepatitis B and C. APRI has been used for predicting liver-related mortality in patients with chronic hepatitis C virus infection or alcoholic liver disease. However, whether APRI could be useful for predicting mortality in chronic hepatitis B virus (HBV) infection remains unevaluated. This study aims to address this knowledge gap. A total of 193 hospitalized chronic HBV-infected patients (cirrhosis, n = 100; noncirrhosis, n = 93) and 88 healthy subjects were retrospectively enrolled. All patients were followed up for 4 months. Mortality that occurred within 90 days of hospital stay was compared among patients with different APRI. APRI predictive value was evaluated by univariate and multivariate regression embedded in a Cox proportional hazards model. APRI varied significantly in our cohort (range, 0.16–10.00). Elevated APRI was associated with increased severity of liver disease and 3-month mortality in hospitalized patients with HBV-related cirrhosis. Multivariate analysis demonstrated that APRI (odds ratio: 1.456, P < 0.001) and the model for end-stage liver disease score (odds ratio: 1.194, P < 0.001) were 2 independent markers for predicting mortality. APRI is a simple marker that may serve as an additional predictor of 3-month mortality in hospitalized patients with HBV-related decompensated cirrhosis. PMID:26945406

    Background and Objectives Although acute kidney injury (AKI) is the most frequent complication in patients receiving extracorporeal membrane oxygenation (ECMO), few studies have been conducted on the risk factors of AKI. We performed this study to identify the risk factors of AKI associated with in-hospital mortality. Methods Data from 322 adult patients receiving ECMO were analyzed. AKI and its stages were defined according to Kidney Disease Improving Global Outcomes (KDIGO) classifications. Variables within 24 h before ECMO insertion were collected and analyzed for the associations with AKI and in-hospital mortality. Results Stage 3 AKI was associated with in-hospital mortality, with a hazard ratio (HR) (95% CI) of 2.690 (1.472–4.915) compared to non-AKI (p = 0.001). The simplified acute physiology score 2 (SAPS2) and serum sodium level were also associated with in-hospital mortality, with HRs of 1.02 (1.004–1.035) per 1 score increase (p = 0.01) and 1.042 (1.014–1.070) per 1 mmol/L increase (p = 0.003). The initial pump speed of ECMO was significantly related to in-hospital mortality with a HR of 1.333 (1.020–1.742) per 1,000 rpm increase (p = 0.04). The pump speed was also associated with AKI (p = 0.02) and stage 3 AKI (p = 0.03) with ORs (95% CI) of 2.018 (1.129–3.609) and 1.576 (1.058–2.348), respectively. We also found that the red cell distribution width (RDW) above 14.1% was significantly related to stage 3 AKI. Conclusion The initial pump speed of ECMO was a significant risk factor of in-hospital mortality and AKI in patients receiving ECMO. The RDW was a risk factor of stage 3 AKI. PMID:26469793

    Introduction Detection of hepatocellular carcinoma (HCC) in cirrhotic patients remains a serious, unsolved problem, and the risk factors for acute variceal bleeding (AVB) in HCC patients remain unclear. This study aimed to determine the in-hospital mortality (IHM) and factors influencing the clinical outcomes of AVB in patients with liver cirrhosis and HCC. Methods This was a retrospective, non-randomized, clinical study that was conducted in 2014. The study was conducted on 70 patients with liver cirrhosis and HCC presenting by acute upper gastrointestinal bleeding (AUGIH). All patients were examined endoscopically within 24 hours from presentation and bleeding varices accounted for AUGIH. Full medical history, clinical examination, and laboratory and radiologic data were collected from admission charts, and hospital medical records were statistically analyzed with SSPS version 22. Results Thirty-two patients (45.7%) survived and 38 died (54.3%). Survivors are more likely to be Child-Pugh class A or B, and the non-survivors were class C. The Model for End-Stage Liver Disease (MELD) was highly predictive of IHM at an optimized cut-off value of ≥ 12.9. Higher esophageal varices grades and presence of active bleeding on index endoscopy were significant (p < 0.01) in the non-survivors compared to survivors. Complications of liver cirrhosis and associated major comorbidity were significantly higher (p < 0.01) in the non-survivors than the survivors. Univariate logistic regression analysis identified higher Grade Esophageal Varices and number of transfused packed red blood cells units as two independent predictors of IHM. Conclusions IHM was particularly high (54.3%) among HCC patients with AVB who had MELD score > 12.9, higher grade Esophageal Varices, active bleeding on index endoscopy, more increased needs for blood transfusion, longer hospital stay, decompensated liver disease with major comorbidity.

    Our aim was to determine the effect of a national strategy for quality improvement in cancer management (the "Plan Cancer") according to time period and to assess the influence of type and volume of hospital activity on in-hospital mortality (IHM) within a large national cohort of patients operated on for lung cancer.From January 2005 to December 2013, 76 235 patients were included in the French Administrative Database. Patient characteristics, hospital volume of activity and hospital type were analysed over three periods: 2005-2007, 2008-2010 and 2011-2013.Global crude IHM was 3.9%: 4.3% during 2005-2007, 4% during 2008-2010 and 3.5% during 2011-2013 (p<0.01). 296, 259 and 209 centres performed pulmonary resections in 2005-2007, 2008-2010 and 2011-2013, respectively (p<0.01). The risk of death was higher in centres performing <13 resections per year than in centres performing >43 resections per year (adjusted (a)OR 1.48, 95% CI 1.197-1.834). The risk of death was lower in the period 2011-2013 than in the period 2008-2010 (aOR 0.841, 95% CI 0.764-0.926). Adjustment variables (age, sex, Charlson score and type of resection) were significantly linked to IHM, whereas the type of hospital was not.The French national strategy for quality improvement seems to have induced a significant decrease in IHM.

    BACKGROUND: Racial and ethnic disparities in mortality have been demonstrated in several diseases. African Americans are hospitalized at a significantly higher rate than whites for aspiration pneumonia; however, no studies have investigated racial and ethnic disparities in mortality in this population. OBJECTIVE: To assess the independent effect of race and ethnicity on in-hospital mortality among aspiration pneumonia discharges while comprehensively controlling for comorbid diseases, and to assess whether the prevalence and effects of comorbid illness differed across racial and ethnic categories. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 41,581 patients admitted to California hospitals for aspiration pneumonia from 1996 through 1998, using principal and secondary diagnoses present on admission. MEASUREMENT: The primary outcome measure was in-hospital mortality. RESULTS: The adjusted odds of in-hospital death for African-American compared with white discharges [odds ratio (OR)=1.01; 95% confidence interval (CI), 0.91-1.11] was not significantly different. The odds of death for Asian compared with white discharges was significantly lower (OR=0.83; 95% CI, 0.75-0.91). Hispanics had a significantly lower odds of death (OR=0.90; 95% CI, 0.82-0.988) compared to non-Hispanics. Comorbid diseases were more prevalent among African Americans and Asians than whites, and among Hispanics compared to non-Hispanics. Differences in effects of comorbid disease on mortality risk by race and ethnicity were not statistically significant. CONCLUSION: Asians have a lower risk of death, and the risk of death for African Americans is not significantly different from whites in this analysis of aspiration pneumonia discharges. Hispanics have a lower risk of death than non-Hispanics. While there are differences in prevalence of comorbid disease by racial and ethnic category, the effects of comorbid disease on mortality risk do not differ meaningfully by race or

    Objectives Medical comorbidities affect outcome in elderly patients with hip fracture. This study was designed to preliminarily evaluate the usefulness of a hip-fracture unit led by an internal medicine specialist. Methods In-hospital and 3-month outcomes in patients with hip fracture were prospectively evaluated in 121 consecutive patients assessed before and followed after surgery by a multidisciplinary team led by internal medicine specialist; 337 consecutive patients were recalled from ICD-9 discharge records and considered for comparison regarding in-hospital mortality. Results In the intervention period, patients treated within 48 hours were 54% vs. 26% in the historical cohort (P<0.0001). In-hospital mortality remained stable at about 2.3 per 1000 person-days. At 3 months, 10.3% of discharged patients had died, though less than 8% of patients developed postoperative complications (mainly pneumonia and respiratory failure). The presence of more than 2 major comorbidities and the loss of 3 or more BADL were independent predictors of death. 50/105 patients recovered previous functional capacity, but no independent predictor of functional recovery could be identified. Mean length of hospital stay significantly decreased in comparison to the historical cohort (13.6± 4.7 vs 17 ± 5 days, p = 0.0001). Combined end-point of mortality and length of hospitalization < 12 days was significantly lower in study period (27 vs 34%, p <0.0132). Conclusions Identification and stabilization of concomitant clinical problems by internal medicine specialists may safely decrease time to surgery in frail subjects with hip fracture. Moreover, integrated perioperative clinical management may shorten hospital stay with no apparent increase in in-hospital mortality and ultimately improve the outcome. These results are to be confirmed by a larger study presently ongoing at our institution. PMID:27389193

    OBJECTIVES: To identify predictors of in-hospital mortality in patients with acute myocardial infarction undergoing pharmacoinvasive treatment. METHODS: This was an observational, prospective study that included 398 patients admitted to a tertiary center for percutaneous coronary intervention within 3 to 24 hours after thrombolysis with tenecteplase. ClinicalTrials.gov: NCT01791764 RESULTS: The overall in-hospital mortality rate was 5.8%. Compared with patients who survived, patients who died were more likely to be older, have higher rates of diabetes and chronic renal failure, have a lower left ventricular ejection fraction, and demonstrate more evidence of heart failure (Killip class III or IV). Patients who died had significantly lower rates of successful thrombolysis (39% vs. 68%; p = 0.005) and final myocardial blush grade 3 (13.0% vs. 61.9%; p<0.0001). Based on the multivariate analysis, the Global Registry of Acute Coronary Events score (odds ratio 1.05, 95% confidence interval (CI) 1.02-1.09; p = 0.001), left ventricular ejection fraction (odds ratio 0.9, 95% CI 0.89-0.97; p = 0.001), and final myocardial blush grade of 0-2 (odds ratio 8.85, 95% CI 1.34-58.57; p = 0.02) were independent predictors of mortality. CONCLUSIONS: In this prospective study that evaluated patients with ST-segment elevation myocardial infarction treated by a pharmacoinvasive strategy, the in-hospital mortality rate was 5.8%. The Global Registry of Acute Coronary Events score, left ventricular ejection fraction, and myocardial blush were independent predictors of mortality in this high-risk group of acute coronary syndrome patients.

    BACKGROUND: Recent clinical trials have demonstrated benefit with early revascularization following acute myocardial infarction (AMI). Trends in and the association between early revascularization after (ie, 30 days or fewer) AMI and early death were determined. METHODS AND RESULTS: The Statistics Canada Health Person-Oriented Information Database, consisting of hospital discharge records for seven provinces from the Canadian Institute for Health Information Hospital Morbidity Database, was used. If there was no AMI in the preceding year, the first AMI visit within a fiscal year for a patient 20 years of age or older was included. Times to death in hospital and to revascularization procedures were counted from the admission date of the first AMI visit. Mixed model regression analyses with random slopes were used to assess the relationship between early revascularization and mortality. The overall rate of revascularization within 30 days of AMI increased significantly from 12.5% in 1995 to 37.4% in 2003, while the 30-day mortality rate decreased significantly from 13.5% to 10.6%. There was a linearly decreasing relationship – higher regional use of revascularization was associated with lower mortality in both men and women. CONCLUSIONS: These population-based utilization and outcome findings are consistent with clinical trial evidence of improved 30-day in-hospital mortality with increased early revascularization after AMI.

    It is not yet clear whether a difference in in-hospital morality between patients with and without renal insufficiency undergoing percutaneous coronary intervention (PCI) exists. Therefore, the aim of the present study was to investigate if such as association exists in Japan. Data from the Tokai Acute Myocardial Infarction Study II were used. This was a prospective study of all 3274 patients admitted with acute myocardial infarction (AMI) to the 15 participating hospitals from 2001 to 2003. We abstracted the baseline and procedural characteristics as well as in-hospital mortality from detailed chart reviews. Patients were stratified into 2 groups according to the estimated creatinine clearance on admission. The creatinine clearance values were available in 2116, 107 of whom had renal insufficiency. The patients with renal insufficiency were more likely to be older, female, not independent in their daily activities, have lower body mass index and higher heart rate values on admission, lower prevalences of hypercholesterolemia and peptic ulcers, greater prevalences of diabetes, angina, previous heart failure, previous renal failure, previous cerebrovascular disease, aortic aneurysm, worse clinical course such as bleeding, and a multivessel coronary disease. Vasopressors, an intra-aortic balloon pump, and mechanical ventilation were frequently used in the patients with renal insufficiency, while thrombolytics were used less frequently. The patients with renal insufficiency had a higher in-hospital mortality rate than those without. Multivariate analysis identified renal insufficiency as an independent predictor of in-hospital death. The results suggest that renal insufficiency is an independent predictor of in-hospital death among AMI patients undergoing PCI. PMID:17106145

    Abstract Recent epidemiologic studies have showed that candidemia is an important nosocomial infection in hospitalized patients. The majority of candidemia patients were non-neutropenic rather than neutropenic status. The aim of this study was to determine the clinical outcome of non-neutropenic patients with candidemia and to measure the contributing factors for mortality. A total of 163 non-neutropenic patients with candidemia during January 2010 to December 2013 were retrospectively enrolled. The patients’ risk factors for mortality, clinical outcomes, treatment regimens, and Candida species were analyzed. The overall mortality was 54.6%. Candida albicans was the most frequent Candida species (n = 83; 50.9% of patients). Under multivariate analyses, hemodialysis (OR, 4.554; 95% CI, 1.464–14.164) and the use of amphotericin B deoxycholate (OR, 8.709; 95% CI, 1.587–47.805) were independent factors associated with mortality. In contrast, abdominal surgery (OR, 0.360; 95% CI, 0.158–0.816) was associated with a better outcome. The overall mortality is still high in non-neutropenic patients with candidemia. Hemodialysis and use of amphotericin B deoxycholate were independent factors associated with mortality, whereas prior abdominal surgery was associated with a better outcome. PMID:27281087

    Increasing regular physical activity is a key public health goal. One strategy is to change the physical environment to encourage walking and cycling, requiring partnerships with the transport and urban planning sectors. Economic evaluation is an important factor in the decision to fund any new transport scheme, but techniques for assessing the economic value of the health benefits of cycling and walking have tended to be less sophisticated than the approaches used for assessing other benefits. This study aimed to produce a practical tool for estimating the economic impact of reduced mortality due to increased cycling. The tool was intended to be transparent, easy to use, reliable, and based on conservative assumptions and default values, which can be used in the absence of local data. It addressed the question: For a given volume of cycling within a defined population, what is the economic value of the health benefits? The authors used published estimates of relative risk of all-cause mortality among regular cyclists and applied these to levels of cycling defined by the user to produce an estimate of the number of deaths potentially averted because of regular cycling. The tool then calculates the economic value of the deaths averted using the "value of a statistical life." The outputs of the tool support decision making on cycle infrastructure or policies, or can be used as part of an integrated economic appraisal. The tool's unique contribution is that it takes a public health approach to a transport problem, addresses it in epidemiologic terms, and places the results back into the transport context. Examples of its use include its adoption by the English and Swedish departments of transport as the recommended methodologic approach for estimating the health impact of walking and cycling.

    Introduction Circadian rhythm disturbance increases cardiovascular risk but the effects of daylight saving time (DST) transitions on the risk of myocardial infarction (MI) are unclear. Methods We studied association of DST transitions in 2001-2009 with incidence and in-hospital mortality of MI admissions nationwide in Finland. Incidence rations (IR) of observed incidences on seven days following DST transition were compared to expected incidences. Results Incidence of MI increased on Wednesday (IR 1.16; CI 1.01-1.34) after spring transition (6298 patients' cohort). After autumn transition (8161 patients' cohort), MI incidence decreased on Monday (IR 0.85; CI 0.74-0.97) but increased on Thursday (IR 1.15; CI 1.02-1.30). The overall incidence of MI during the week after each DST transition did not differ from control weeks. Patient age or gender, type of MI or in-hospital mortality were not associated with transitions. Renal insufficiency was more common among MI patients after spring transition (OR 1.81; CI 1.06-3.09; p < 0.05). Diabetes was less common after spring transition (OR 0.71; CI 0.55-0.91; p = 0.007), but more common after autumn transition (OR 1.21; 1.00-1.46; p < 0.05). Conclusions DST transitions are followed by changes in the temporal pattern but not the overall rate of MI incidence. Comorbidities may modulate the effects DST transitions. KEY MESSAGES Both spring and autumn daylight saving time transitions changed the temporal occurrence pattern but not the overall incidence of myocardial infarction occurrence on the week following the clock shift. The age or gender distribution of patients, ratio of different types of myocardial infarctions or in-hospital mortality were not affected by clock shifts. The effect of daylight saving time transitions on MI incidence may be modified by the presence of diabetes. PMID:26679065

    Most patients with single ventricle congenital heart disease are now expected to survive to adulthood. Co-morbid medical conditions (CMCs) are common. We sought to identify risk factors for increased hospital resource utilization and in-hospital mortality in adults with single ventricle. We analyzed data from the 2001 to 2011 Nationwide Inpatient Sample database in patients aged ≥18 years admitted to nonteaching general hospitals (NTGHs), TGHs, and pediatric hospitals (PHs) with either hypoplastic left heart syndrome, tricuspid atresia or common ventricle. National estimates of hospitalizations were calculated. Elixhauser CMCs were identified. Length of stay (LOS), total hospital costs, and effect of CMCs were determined. Age was greater in NTGH (41.5 ± 1.3 years) than in TGH (32.8 ± 0.5) and PH (25.0 ± 0.6; p <0.0001). Adjusted LOS was shorter in NTGH (5.6 days) than in PH (9.7 days; p <0.0001). Adjusted costs were higher in PH ($56,671) than in TGH ($31,934) and NTGH ($18,255; p <0.0001). CMCs are associated with increased LOS (p <0.0001) and costs (p <0.0001). Risk factors for in-hospital mortality included increasing age (odds ratio [OR] 5.250, CI 2.825 to 9.758 for 45- to 64-year old vs 18- to 30-year old), male gender (OR 2.72, CI 1.804 to 4.103]), and the presence of CMC (OR 4.55, CI 2.193 to 9.436) for 2 vs none). No differences in mortality were found among NTGH, TGH, and PH. Cardiovascular procedures were more common in PH hospitalizations and were associated with higher costs and LOS. CMCs increase costs and mortality. In-hospital mortality is increased with age, male gender, and the presence of hypoplastic left heart syndrome. PMID:27291967

    Infective endocarditis (IE) is a highly morbid disease, for which most outcomes data come from patients with left-sided valvular lesions. Echocardiographic findings such as vegetation size and prosthetic valve involvement have been identified as important predictors of mortality in left-sided IE, but predictors of outcomes in right-sided IE are less well characterized. Therefore, the aim of this study was to identify clinical and echocardiographic findings predictive of mortality in tricuspid valve (TV) IE. We retrospectively reviewed all echocardiograms showing TV vegetations that were performed at the Massachusetts General Hospital from January 1, 2003, to December 31, 2013. We identified 105 patients who had echocardiographic evidence of TV vegetations and a definite clinical diagnosis of IE based on the modified Duke's criteria but did not have intracardiac device-associated vegetations. Of the 105 patients, 88 survived until discharge. Clinical and echocardiographic factors that positively correlated with in-hospital mortality included age (p = 0.002), immunosuppression status (p = 0.016), blood urea nitrogen level (p = 0.029), Candida causative organism (p = 0.025), left ventricular ejection fraction <40% (p = 0.027), right ventricular (RV) systolic dysfunction (p = 0.009), and estimated RV systolic pressure >40 mm Hg (p = 0.040). Of these factors, immunosuppression status, blood urea nitrogen level, and RV systolic dysfunction were independently associated with increased in-hospital mortality. In conclusion, RV systolic dysfunction may serve as an echocardiographic marker to aid clinicians in identifying high-risk patients with right-sided IE for more aggressive therapy. PMID:27392511

    Background The inverse association between education and mortality has grown stronger the last decades in many countries. During the same period, gains in life expectancy have been concentrated to older ages; still, old-age mortality is seldom the focus of attention when analyzing trends in the education-mortality gradient. It is further unknown if increased educational inequalities in mortality are preceded by increased inequalities in morbidity of which hospitalization may be a proxy. Methods Using administrative population registers from 1971 and onwards, education-specific annual changes in the risk of death and hospital admission were estimated with complimentary log-log models. These risk changes were supplemented by estimations of the ages at which 25, 50, and 75% of the population had been hospitalized or died (after age 60). Results The mortality decline among older people increasingly benefitted the well-educated over the less well-educated. This inequality increase was larger for the younger old, and among men. Educational inequalities in the age of a first hospital admission generally followed the development of growing gaps, but at a slower pace than mortality and inequalities did not increase among the oldest individuals. Conclusions Education continues to be a significant predictor of health and longevity into old age. That the increase in educational inequalities is greater for mortality than for hospital admissions (our proxy of overall morbidity) may reflect that well-educated individuals gradually have obtained more possibilities or resources to survive a disease than less well-educated individuals have the last four decades.

    Open surgical repair (OSR) is a conventional surgical method used in the repair a ruptured abdominal aortic aneurysm (AAA); however, OSR results in high perioperative mortality rates. The level of serum angiotensin-converting enzyme 2 (ACE2) has been reported to be an independent risk factor for postoperative in-hospital mortality following major cardiopulmonary surgery. In the present study, the association of serum ACE2 levels with postoperative in-hospital mortality was investigated in patients undergoing OSR for ruptured AAA. The study enrolled 84 consecutive patients underwent OSR for ruptured AAA and were subsequently treated in the intensive care unit. Patients who succumbed postoperatively during hospitalization were defined as non-survivors. Serum ACE2 levels were measured in all patients prior to and following the surgery using ELISA kits. The results indicated that non-survivors showed significantly lower mean preoperative and postoperative serum ACE2 levels when compared with those in survivors. Multivariate logistic regression analysis also showed that, subsequent to adjusting for potential confounders, the serum ACE2 level on preoperative day 1 showed a significant negative association with the postoperative in-hospital mortality. This was confirmed by multivariate hazard ratio analysis, which showed that, subsequent to adjusting for the various potential confounders, the risk of postoperative in-hospital mortality remained significantly higher in the two lowest serum ACE2 level quartiles compared with that in the highest quartile on preoperative day 1. In conclusion, the present study provided the first evidence supporting that the serum ACE2 level is an independent risk factor for the in-hospital mortality following OSR for ruptured AAA. Furthermore, low serum ACE2 levels on preoperative day 1 were found to be associated with increased postoperative in-hospital mortality. Therefore, the serum ACE2 level on preoperative day 1 may be a potential

    Objective To assess the sex difference in hospital mortality following ST elevation myocardial infarction (STEMI) in China. Design Observational study of patients enrolled into a large trial, adjusting for age, presenting characteristics and hospital treatments using logistic regression. Settings 1250 hospitals in China during 1999–2005. Patients 42 683 STEMI patients, including 31 309 men and 11 374 women. Intervention In the original trial, all patients received 162 mg of aspirin plus 75 mg of clopidogrel daily or matching placebo and metoprolol (15 mg intravenous then 200 mg oral daily) or matching placebo. All other aspects of patients' treatments were at the discretion of responsible doctors. Major outcomes Hospital mortality from any cause during the scheduled trial treatment period (ie, up to 4 weeks in hospital). Results Overall, 8% of the patients died in hospital, with the crude hospital mortality being twice as high in women as in men (12.6% vs 6.3%). After adjusting for age, the sex difference in hospital mortality attenuated but remained highly significant (OR 1.54; 95% CI 1.43 to 1.66). Further adjustment for other baseline characteristics and for the treatments given in hospital had little effect on the sex difference in hospital mortality (OR 1.50, 95% CI 1.38 to 1.62). The difference in hospital mortality was greater at a younger age, with the adjusted ORs being 2.14, 1.70, 1.48 and 1.18, respectively, for ages <55, 55–64, 65–74 and ≥75 years (p=0.0001 for trend). Conclusion Compared with men of the same age, women had approximately a 50% higher mortality following hospital admission for STEMI, with a particularly higher excess risk at age <55 years.

    Background Thyroid cancer is a tumor with a low but growing incidence in Spain. This study sought to depict its spatial municipal mortality pattern, using the classic model proposed by Besag, York and Mollié. Methods It was possible to compile and ascertain the posterior distribution of relative risk on the basis of a single Bayesian spatial model covering all of Spain's 8077 municipal areas. Maps were plotted depicting standardized mortality ratios, smoothed relative risk (RR) estimates, and the posterior probability that RR > 1. Results From 1989 to 1998 a total of 2,538 thyroid cancer deaths were registered in 1,041 municipalities. The highest relative risks were mostly situated in the Canary Islands, the province of Lugo, the east of La Coruña (Corunna) and western areas of Asturias and Orense. Conclusion The observed mortality pattern coincides with areas in Spain where goiter has been declared endemic. The higher frequency in these same areas of undifferentiated, more aggressive carcinomas could be reflected in the mortality figures. Other unknown genetic or environmental factors could also play a role in the etiology of this tumor. PMID:17173668

    A retrospective study was conducted to compare the performance of Child-Pugh and Model for End-Stage Liver Diseases (MELD) scores for predicting the in-hospital mortality of acute upper gastrointestinal bleeding (UGIB) in patients with liver cirrhosis. A total of 145 patients with a diagnosis of liver cirrhosis and acute UGIB between July 2013 and June 2014 were retrospectively analyzed (male/female: 94/51; mean age: 56.77±11.33 years; Child-Pugh class A/B/C: 46/64/35; mean Child-Pugh score: 7.88±2.17; mean MELD score: 7.86±7.22). The in-hospital mortality was 8% (11/145). Areas under receiving-operator characteristics curve (AUROC) for predicting the in-hospital mortality were compared between MELD and Child-Pugh scores. AUROCs for predicting the in-hospital mortality for Child-Pugh and MELD scores were 0.796 (95% confidence interval [CI]: 0.721-0.858) and 0.810 (95% CI: 0.736-0.870), respectively. The discriminative ability was not significant different between the two scoring systems (P=0.7241). In conclusion, Child-Pugh and MELD scores were similar for predicting the in-hospital mortality of acute UGIB in cirrhotic patients. PMID:25785053

    A mortality study was carried out in two factories producing stainless steel in order to assess lung cancer risk among workers employed in coke oven, blast and open hearth furnaces, foundry, electric furnace, hot and cold rolling mills and pickling areas. Occupational exposures of interest were chromium compounds, nickel compounds, polycyclic aromatic hydrocarbons (PAH), silica and asbestos. All male workers having at least one year of employment between 01.01.1960 and 31.12.1990 were followed up for mortality. The vital status was assessed from birth place registries. Complete job histories since date of first employment were abstracted from the company files. The smoking habits of 50% of the cohort members were known from medical records. The observed number of deaths (obs) were compared with the expected ones based on regional rates with adjustment for age, sex and calendar time (Standardized Mortality Ratio, SMR). The cohorts included 6324 (factory 1) and 5270 (factory 2) workers. The overall mortality did not differ markedly from that expected in both factories: SMR = 0.95 (obs = 1540, p = 0.05) in factory 1 and SMR = 1.06 (obs = 916, non-significant) in factory 2. SMRs for lung cancer did not differ from unity, respectively 0.99 (obs = 105) and 1.00 (obs = 54), in whole cohorts. Non-significant lung cancer excesses were observed among workers of some workshops where exposures of interest might have occurred: coke oven (SMR = 2.04), blast furnace (SMR = 1.36), open hearth furnace (SMR = 1.75), hot rolling mills (SMR = 1.29). These processes, however, are no longer involved in the study factories. Furthermore, no lung cancer excess was observed among workers employed in current workshops: electric furnaces and cold rolling mills. PMID:7732197

    Background Clostridium difficile infection (CDI) severity has increased, especially among hospitalized elderly. We evaluated clinical factors to predict mortality following CDI. Methods We collected data from inpatients diagnosed with CDI at US academic medical center (HSR-IRB# 13630). We evaluated age, Charlson comorbidity index (CCI), admission from a long-term care facility (LTCF), intensive care unit (ICU) at time of diagnosis, white blood cell count (WBC), blood urea nitrogen (BUN), low body mass index (BMI), and delirium as possible predictors. A parsimonious predictive model was chosen using Akaike information criterion (AIC) and a best subsets model selection algorithm. Area under the ROC curve was used to assess the model’s comparative; with AIC as selection criterion for all subsets to measure fit and control for over-fitting. Results From 362 subjects, the selected model included CCI, WBC, BUN, ICU, and delirium. The logistic regression coefficients were converted to a points scale and calibrated so that each unit on the CCI contributed 2 points, ICU contributed 5, unit of WBC (natural log scale) contributed 3, unit of BUN contributed 5, and delirium contributed 11. Discussion Our model shows substantial ability to predict short term mortality in patients hospitalized with CDI. Conclusion Patients who were diagnosed in the ICU and developed delirium are at highest risk for dying within 30 days of CDI diagnosis. PMID:25920706

    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.

    Objective: To study the distribution of weight for age standard score (Z score) in pediatric cardiac surgery and its effect on in-hospital mortality. Introduction: WHO recommends Standard Score (Z score) to quantify and describe anthropometric data. The distribution of weight for age Z score and its effect on mortality in congenital heart surgery has not been studied. Methods: All patients of younger than 5 years who underwent cardiac surgery from July 2007 to June 2013, under single surgical unit at our institute were enrolled. Z score for weight for age was calculated. Patients were classified according to Z score and mortality across the classes was compared. Discrimination and calibration of the for Z score model was assessed. Improvement in predictability of mortality after addition of Z score to Aristotle Comprehensive Complexity (ACC) score was analyzed. Results: The median Z score was -3.2 (Interquartile range -4.24 to -1.91] with weight (mean±SD) of 8.4 ± 3.38 kg. Overall mortality was 11.5%. 71% and 52.59% of patients had Z score < -2 and < -3 respectively. Lower Z score classes were associated with progressively increasing mortality. Z score as continuous variable was associated with O.R. of 0.622 (95% CI- 0.527 to 0.733, P < 0.0001) for in-hospital mortality and remained significant predictor even after adjusting for age, gender, bypass duration and ACC score. Addition of Z score to ACC score improved its predictability for in-hosptial mortality (δC - 0.0661 [95% CI - 0.017 to 0.0595, P = 0.0169], IDI- 3.83% [95% CI - 0.017 to 0.0595, P = 0.00042]). Conclusion: Z scores were lower in our cohort and were associated with in-hospital mortality. Addition of Z score to ACC score significantly improves predictive ability for in-hospital mortality.

    Introduction: The objective was to examine the role of statins in modulating post-STEMI inflammation and related mortality. Methods: A total of 404 patients with STEMI were reviewed. Demographics, comorbidities, laboratory values, and outcomes were collected. The patients were grouped as STATIN and NOSTAT based on the use of statin drugs at the time of admission. Ninety-seven patients were receiving statin drugs. Results: The patients in the STATIN group were more likely to be hypertensive (53.6%), diabetic (37.1%) and to have previous coronary revascularization (9.3%). Following propensity matching of 89 patients in STATIN group to an equal number of patients in NOSTAT controls had lower neutrophil count 7.8 (6.8-8.4) compared to those in the NOSTAT group 9.1 (7.9-10.1). Although there was no difference in-hospital mortality between the two groups, the incidence of pump failure was lower in the STATIN group (5.6% vs. 15.7%; P < 0.01). Conclusion: Statin treatment prior to STEMI mitigates the cellular inflammatory response after the myocardial infarction, as evidenced by lower leukocyte and neutrophil cell counts in the STATIN group.

    Background Pharmacist-led medication review services have been assessed in the meta-analyses in hospital. Of the 135 relevant articles located, 21 studies met the inclusion criteria; however, there was no statistically significant difference found between pharmacists’ interventions and usual care for mortality (odds ratio 1.50, 95% confidence interval 0.65, 3.46, P=0.34). These analyses may not have found a statistically significant effect because they did not adequately control the wide variation in the delivery of care and patient selection parameters. Additionally, the investigators did not conduct research on the cases of death specifically and did not identify all possible drug-related problems (DRPs) that could cause or contribute to mortality and then convince physicians to correct. So there will be a condition to use a more precise approach to evaluate the effect of clinical pharmacist interventions on the mortality rates of hospitalized cardiac patients. Objective To evaluate the impact of the clinical pharmacist as a direct patient-care team member on the mortality of all patients admitted to the cardiology unit. Methods A comparative study was conducted in a cardiology unit of a university-affiliated hospital. The clinical pharmacists did not perform any intervention associated with improper use of medications during Phase I (preintervention) and consulted with the physicians to address the DRPs during Phase II (postintervention). The two phases were compared to evaluate the outcome, and propensity score (PS) matching was applied to enhance the comparability. The primary endpoint of the study was the composite of all-cause mortality during Phase I and Phase II. Results Pharmacists were consulted by the physicians to correct any drug-related issues that they suspected may cause or contribute to a fatal outcome in the cardiology ward. A total of 1,541 interventions were suggested by the clinical pharmacist in the study group; 1,416 (92.0%) of them were

    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

    In February 2012, 100% mortality was reported in a herd with 79 local sheep that were kept around of Abhar, Northwest of Iran. The ration for adult sheep was daily mixed (40 kg straw, 25 kg wheat and 2 kg Vit-C premix) and accidentally 1 500 g of salinomycin (Salinomycin 12% Premix; Aras Bazar Laboratories, Iran) had been added to the ration (22388 mg/kg = 22388 ppm) and overnight was fed to herd. At the morning, 78 sheep were founded dead and one of them showed convulsive seizures. Postmortem examination revealed pulmonary congestion and edema, hemorrhages in abomasum, large pale kidney and white streak lines in myocardium. Main histopathologic lesions were extensive subepicardial and intercardiomyofibers hemorrhages, extensive cardiomyolysis and myocarditis in heart, severe hyperemia and extensive acute tubular necrosis (ATN) in kidneys and focal necrosis and retention of bile cholangitis in the liver. In this study, on the basis of the history, observation of the ionophore remnant in the ration, clinical signs, gross and histopathological findings, acute salinomycin intoxication is definitely diagnosed.

    The impact of mortality due to congenital anomalies in single-delivery births was compared in 1960 and 1980 birth cohorts; data were used from the 1960 National Center for Health Statistics national linkage of birth and death certificates and the 1980 National Infant Mortality Surveillance project. In 1960 there were 14,714 deaths due to congenital anomalies, compared with 8,674 in 1980, a 41 percent reduction. The infant mortality risk (IMR) due to congenital anomalies fell 31 percent. This is in contrast with the observed 54 percent decline in IMR due to all causes. This reduction in mortality due to congenital anomalies occurred for both whites and blacks in the postneonatal period and for whites only in the neonatal period. Changes ranged from a 1.8 percent increase for the black neonatal mortality risk to a 46.6 percent decrease for the white postneonatal mortality risk. In spite of these relative reductions, the absolute percentage of all infant deaths due to congenital anomalies had increased from 15.8 percent in 1960 to 24.1 percent in 1980. Two categories, cardiovascular and central nervous system anomalies, accounted for 72 percent of infant deaths due to congenital anomalies in 1960 and for 59 percent in 1980; cardiovascular anomalies accounted for 48 percent of all deaths due to congenital anomalies in 1960 and 40 percent in 1980. Infant mortality risks in the United States showed a 2:1 black to white ratio in both 1960 and 1980. However, for infant mortality due to congenital anomalies, the black and white mortality risks were approximately equal in both 1960 and 1980. For infants with birth weights of 500-2,499 g, the risk of neonatal mortality for blacks was less than half the risk for whites. PMID:3104974

    Objective. We aimed to systematically assess the efficacy of Chinese herbal medicine (CHM) as an adjunctive therapy on in-hospital mortality in patients with acute kidney injury (AKI). Methods. We did a systematic review of articles published in any language up until Jun 23, 2015, by searching PubMed, Embase, the Cochrane Library, CBM, and CNKI. We included all RCTs that compared outcomes of patients with AKI taking CHM plus Western treatment (WT) with those taking WT alone. We applied Cochrane risk-of-bias tool to assess the methodological quality of the included trials. Results. Of 832 citations, 15 studies involving 966 patients met inclusion criteria. The methodological quality was assessed with unclear risk of bias. In the primary outcome of meta-analysis, pooled outcome of in-hospital mortality showed that patients randomly assigned to CHM treatment group were associated with low risk of in-hospital mortality compared with those randomly assigned to WT alone (RR = 0.41; 95% CI = 0.24 to 0.71; P = 0.001). Conclusions. CHM as an adjunctive therapy is associated with a decreased risk of in-hospital mortality compared with WT in patients with AKI. Further studies with high quality and large sample size are needed to verify our conclusions. PMID:27127528

    2012-01-01

    Background While the benefits or otherwise of early hip fracture repair is a long-running controversy with studies showing contradictory results, this practice is being adopted as a quality indicator in several health care organizations. The aim of this study is to analyze the association between early hip fracture repair and in-hospital mortality in elderly people attending public hospitals in the Spanish National Health System and, additionally, to explore factors associated with the decision to perform early hip fracture repair. Methods A cohort of 56,500 patients of 60-years-old and over, hospitalized for hip fracture during the period 2002 to 2005 in all the public hospitals in 8 Spanish regions, were followed up using administrative databases to identify the time to surgical repair and in-hospital mortality. We used a multivariate logistic regression model to analyze the relationship between the timing of surgery (< 2 days from admission) and in-hospital mortality, controlling for several confounding factors. Results Early surgery was performed on 25% of the patients. In the unadjusted analysis early surgery showed an absolute difference in risk of mortality of 0.57 (from 4.42% to 3.85%). However, patients undergoing delayed surgery were older and had higher comorbidity and severity of illness. Timeliness for surgery was not found to be related to in-hospital mortality once confounding factors such as age, sex, chronic comorbidities as well as the severity of illness were controlled for in the multivariate analysis. Conclusions Older age, male gender, higher chronic comorbidity and higher severity measured by the Risk Mortality Index were associated with higher mortality, but the time to surgery was not.

    Background and Purpose: Intracerebral hemorrhage (ICH) constitutes now 52% of all strokes. Despite of its deadly pattern, locally there is no clinical grading scale for ICH-related mortality prediction. The first objective of this study was to develop a risk stratification scale (Kinshasa ICH score) by assessing the strength of independent predictors and their association with in-hospital 30-day mortality. The second objective of the study was to create a specific local and African model for ICH prognosis. Materials and Methods: Age, sex, hypertension, type 2 diabetes mellitus (T2DM), smoking, alcohol intake, and neuroimaging data from CT scan (ICH volume, Midline shift) of patients admitted with primary ICH and follow-upped in 33 hospitals of Kinshasa, DR Congo, from 2005 to 2008, were analyzed using logistic regression models. Results: A total of 185 adults and known hypertensive patients (140 men and 45 women) were examined. 30-day mortality rate was 35% (n=65). ICH volume>25 mL (OR=8 95% CI: 3.1-20.2; P<0.0001), presence of coma (OR=6.8 95% CI 2.6-17.4; P<0.0001) and left hemispheric site of ICH (OR 2.6 95% CI: 1.1-6; P=0.027) were identified as significant and independent predictors of 30-day mortality. Midline shift > 7 mm, a consequence of ICH volume, was also a significant predictor of mortality. The Kinshasa ICH score was the sum of individual points assigned as follows: Presence of coma coded 2 (2 × 2 = 4), absence of coma coded 1 (1 × 2 = 2), ICH volume>25 mL coded 2 (2 × 2=4), ICH volume of ≤25 mL coded 1(1 × 2=2), left hemispheric site of ICH coded 2 (2 × 1=2), and right hemispheric site of hemorrhage coded 1(1 × 1 = 1). All patients with Kinshasa ICH score ≤7 survived and the patients with a score >7 died. In considering sex influence (Model 3), points were allowed as follows: Presence of coma (2 × 3 = 6), absence of coma (1 × 3 = 3), men (2 × 2 = 4), women (1 × 2 = 2), midline shift ≤7 mm (1 × 3 = 3), and midline shift >7 mm (2 × 3

    Background The diagnosis of heart failure (HF) is often difficult and underestimated in very elderly comorbid patients, especially when an echocardiographic evaluation is not available or feasible. Aim: to evaluate NT-proBNP values and their correlation with in-hospital mortality in a population of very elderly hospitalized for medical conditions other than HF. Methods We performed a prospective observational study on 403 very elderly admitted to an Internal Medicine and Geriatrics Department. Exclusion criterion was an admission diagnosis of HF. Patients with at least one symptom or sign compatible with HF were tested for NT-proBNP. NT-proBNP values < 300 pg/ml were considered as an age-independent exclusion criterion for HF (high negative predictive value), while NT-proBNP values ≥ 1800 pg/ml were considered as a diagnostic criterion. Main comorbidities and laboratory parameters were considered to adjust regression analyses between NT-proBNP and in-hospital mortality. Results NT-proBNP values ≥ 1800 pg/ml were present in 61.0% of patients and 32.8% of patients laid between 300 ≤ NT-proBNP < 1800 pg/ml values. NT-proBNP values were associated with the main indices of disease severity/organ failure considered such as reduced eGFR, reduced albumin and elevated CRP. NT-proBNP values ≥ 1800 pg/ml and ln(NT-proBNP) values were significantly associated with in-hospital mortality independently from the main comorbidities and lab parameters considered. The patients, who were already taking ACE inhibitors/Angiotensin Receptor Blockers before admission, showed lower in-hospital mortality. Conclusions Testing for NT-proBNP should be strongly recommended in the hospitalized very elderly, because of the very high prevalence of underlying HF and its impact on in-hospital mortality, to identify an underlying cardiac involvement that requires appropriate treatment.

    Background Though evidence is limited in Japan, clinical controlled studies overseas have revealed that specialized care units are associated with better outcomes for acute stoke patients. This study aimed to examine the effectiveness of hospital functions for acute care of ischemic stroke on in-hospital mortality, with statistical accounting for referral bias. Methods We derived data from a large Japanese claim-based inpatient database linked to the Survey of Medical Care Institutions and Hospital Report data. We compared the mortality of acute ischemic stroke patients (n = 41 476) in hospitals certified for acute stroke treatment with that in non-certified institutions. To adjust for potential referral bias, we used differential distance to hospitals from the patient’s residence as an instrumental variable and constructed bivariate probit models. Results With the ordinary probit regression model, in-hospital mortality in certified hospitals was not significantly different from that in non-certified institutions. Conversely, the model with the instrumental variable method showed that admission to certified hospitals reduced in-hospital mortality by 30.7% (P < 0.001). This difference remained after adjusting for hospital size, volume, staffing, and intravenous use of tissue plasminogen activator. Conclusions Comparison accounting for referral selection found that certified hospital function for acute ischemic stroke care was associated with significantly lower in-hospital mortality. Our results indicate that organized stroke care—with certified subspecialty physicians and around-the-clock availability of personnel, imaging equipment, and emergency neurosurgical procedures in an intensive stroke care unit—is effective in improving outcomes in acute ischemic stroke care.

    Objectives: To describe trends in hospital admissions and mortality from congestive heart failure in the elderly population aged 65 years and over in Singapore, 1991 to 1998. Design: Analysis of trends and population subgroup differences in rates of hospital admission and mortality for a primary diagnosis of congestive heart failure, classified as ICD-9, codes 428, 402.0, 402.11, and 402.91. Setting: The state of Singapore (multiethnic population of three million: Chinese 77%, Malay 14%, Indian 8%). Results: Congestive heart failure accounted for 4.5% of all hospital admissions and 2.5% of overall mortality in this age group. Age adjusted hospital admission rates for congestive heart failure increased by 38% (from 85.4 per 10 000 in 1991 to 110.3 per 10 000 in 1998), while mortality decreased by 20% (from 7.3 per 10 000 in 1991 to 6.1 per 10 000 in 1998). The decline in mortality was greater in women than in men. There were no sex differences in the rates of hospital admission, but there were significant ethnic differences in admissions and mortality. Thus hospital admissions for congestive heart failure were about 35% higher in both Malays and Indians than in Chinese; and mortality was 3.5 times higher in Malays, but was about the same in Indians and Chinese. Over the period studied, mortality from congestive heart failure declined in both Chinese and Indians, but rose in Malays. The increases in hospital admissions were similar in both sexes and all ethnic groups. Conclusions: An increasing rate of hospital admission accompanied by declining mortality from congestive heart failure is occurring in elderly people in this Asian multiethnic population. However, there are pronounced ethnic differences, with both Malays and Indians showing higher hospital admission rates than Chinese, and Malays showing a rising mortality as opposed to the falling mortality in the other ethnic groups.

    Background. Severe falciparum malaria with human immunodeficiency virus (HIV) coinfection is common in settings with a high prevalence of both diseases, but there is little information on whether HIV affects the clinical presentation and outcome of severe malaria. Methods. HIV status was assessed prospectively in hospitalized parasitemic adults and children with severe malaria in Beira, Mozambique, as part of a clinical trial comparing parenteral artesunate versus quinine (ISRCTN50258054). Clinical signs, comorbidity, complications, and disease outcome were compared according to HIV status. Results. HIV-1 seroprevalence was 11% (74/655) in children under 15 years and 72% (49/68) in adults with severe malaria. Children with HIV coinfection presented with more severe acidosis, anemia, and respiratory distress, and higher peripheral blood parasitemia and plasma Plasmodium falciparum histidine-rich protein-2 (PfHRP2). During hospitalization, deterioration in coma score, convulsions, respiratory distress, and pneumonia were more common in HIV-coinfected children, and mortality was 26% (19/74) versus 9% (53/581) in uninfected children (P < .001). In an age- and antimalarial treatment–adjusted logistic regression model, significant, independent predictors for death were renal impairment, acidosis, parasitemia, and plasma PfHRP2 concentration. Conclusions. Severe malaria in HIV-coinfected patients presents with higher parasite burden, more complications, and comorbidity, and carries a higher case fatality rate. Early identification of HIV coinfection is important for the clinical management of severe malaria. PMID:22752514

    Spinal fusion surgery has increased dramatically and patients presenting for surgery are often more medically challenging. We hypothesized that advanced age and coexisting morbidities have increased in the population undergoing spinal fusion and are associated with greater risks for immediate complications and mortality. The Nationwide Inpatient Sample was retrospectively reviewed for discharges after a principal procedure code for elective spinal fusion. Total records meeting study inclusion criteria were 254,640. Coexisting morbidities were tabulated using Elixhauser comorbidities and the Charlson comorbidity index. Logistic regression identified risk factors associated with in-hospital mortality and early complications. The largest increase in spinal fusion surgery was in patients >65 years. Overall, those with at least 1 comorbidity increased (49% to 62%; P=0.002), as did mean Charlson index (0.146 to 0.202; P<0.001). In-hospital mortality was 0.13%, but 0.29%, and 0.64% for patients of 65 to 74, and those >or=75 years, respectively. Adjusted odds ratios for complications in 65-year to 74-year olds versus <65 years was 1.78 (95% confidence interval, 1.71-1.84; P<0.001), and for mortality 3.81 (95% confidence interval, 2.62-5.55; P<0.001); risks increased with the number of coexisting morbidities. Congestive heart failure, chronic pulmonary disease, coagulopathy, metastatic cancer, renal failure, and weight loss significantly correlated with in-hospital mortality, whereas hypertension or hypothyroidism had, unexpectedly, the opposite effect. Although it is known for some other forms of complex surgery, we showed that elderly and medically complex spinal fusion patients were at increased risk for in-hospital mortality and early complications. The majority of complications were operative, pulmonary, cardiovascular, or genito-urinary. Patient risk correlated with the number and nature of coexisting morbidities. PMID:19098620

    Introduction: Anaemia is associated with increased post-operative morbidity and mortality. We retrospectively assess the relationship between preoperative anaemia and in-hospital mortality in valvular cardiac surgical population. Materials and Methods: Data from consecutive adult patients who underwent valvular repair/replacement at our institute from January 2010 to April 2014 were collected from hospital records. Anaemia was defined according to WHO criteria (hemoglobin <13g/dl for males and <12g/dl for females). 1:1 matching was done for anemic and non-anemic patients based on propensity for potentially confounding variables. Logistic regression was used to evaluate the relationship between anaemia and in-hospital mortality. MatchIt package for R software was used for propensity matching and SPSS 16.0.0 was used for statistical analysis. Results: 2449 patients undergoing valvular surgery with or without coronary artery grafting were included. Anaemia was present in 37.1% (33.91% among males & 40.88% among females). Unadjusted OR for mortality was 1.6 in anemic group (95% Confidence Interval [95% CI] – 1.041-2.570; p=0.033). 1:1 matching was done on the basis of propensity score for anaemia (866 pairs). Balancing was confirmed using standardized differences. Anaemia had an OR of 1.8 for mortality (95% CI- 1.042 to 3.094, P=0.035). Hematocrit of < 20 on bypass was associated with higher mortality. Conclusion: Preoperative anaemia is an independent risk factor associated with in-hospital mortality in patients undergoing valvular heart surgery. PMID:26139743

    Objective Current practice guidelines recommend the routine use of several cardiac medications early in the course of acute myocardial infarction (AMI). Our objective was to analyze temporal trends in medication use and in-hospital mortality of AMI patients in a Chinese population. Methods This is a retrospective observational study using electronic medical records from the hospital information system (HIS) of 14 Chinese hospitals. We identified 5599 patients with AMI between 2005 and 2011. Factors associated with medication use and in-hospital mortality were explored by using hierarchical logistic regression. Results The use of several guideline-recommended medications all increased during the study period: statins (57.7%–90.1%), clopidogrel (61.8%–92.3%), β-Blockers (45.4%–65.1%), ACEI/ARB (46.7%–58.7%), aspirin (81.9%–92.9%), and the combinations thereof increased from 24.9% to 42.8% (P<0.001 for all). Multivariate analyses showed statistically significant increases in all these medications. The in-hospital mortality decreased from 15.9% to 5.7% from 2005 to 2011 (P<0.001). After multivariate adjustment, admission year was still a significant factor (OR = 0.87, 95% CI 0.79–0.96, P = 0.007), the use of aspirin (OR = 0.64, 95% CI 0.46–0.87), clopidogrel (OR = 0.44, 95% CI 0.31–0.61), ACEI/ARB (OR = 0.73, 95% CI 0.56–0.94) and statins (OR = 0.54, 95% CI 0.40–0.73) were associated with a decrease in in-hospital mortality. Patients with older age, cancer and renal insufficiency had higher in-hospital mortality, while they were generally less likely to receive all these medications. Conclusion Use of guideline-recommended medications early in the course of AMI increased between 2005 and 2011 in a Chinese population. During this same time, there was a decrease in in-hospital mortality. PMID:25706944

    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

    To search for potentially carcinogenic effects of electromagnetic field exposures, the author conducted a population-based study of mortality in US amateur radio operators. Ascertainment of Washington State and California amateur radio operators (67,829 persons) was done through the 1984 US Federal Communications Commission Amateur Radio Station and/or Operator License file. A total of 2485 deaths were located for the period from January 1, 1979 through December 31, 1984, in a population of amateur radio operators which accumulated 232,499 person-years at risk. The all-cause standardized mortality ratio (SMR) was 71, but a statistically significant increased mortality was seen for cancers of the other lymphatic tissues (SMR = 162), a rubric which includes multiple myeloma and non-Hodgkin's lymphomas. The all-leukemia standardized mortality ratio was slightly, but nonsignificantly, elevated (SMR = 124). However, mortality due to acute myeloid leukemia was significantly elevated (SMR = 176).

    It is still controversial whether percutaneous coronary intervention (PCI) is effective in improving in-hospital survival in very elderly patients. Therefore, using data from the Tokai Acute Myocardial Infarction Study II, we studied the effect of emergency PCI on the in-hospital mortality of very elderly (80+ years of age) patients with acute myocardial infarction (AMI). The study was a prospective study of all consecutive patients admitted to the 15 acute care hospitals in the Tokai region with the diagnosis of AMI from 2001 to 2003. A total of 211 patients undergoing emergency PCI and 176 patients not undergoing PCI were included in the present analysis. We compared the baseline and procedural characteristics and the clinical outcomes between the 2 groups. Patients without emergency PCI were older and had an increased prevalence of female gender, ADL impairment, and dementia in comparison with those with PCI. They also showed poorer clinical conditions. They were less likely to be transferred to intensive care or coronary care units and to be given intra-aortic balloon pumps. The patients with emergency PCI had nearly one-third the in-hospital mortality rate of the patients without emergency PCI. According to multivariate analysis, emergency PCI was still identified as an independent predictor of in-hospital death, with an adjusted odds ratio of 0.26 (95% CI, 0.07-0.97). The results indicated that emergency PCI has a preventative effect on in-hospital mortality in Japanese AMI patients 80 years of age and older. PMID:17106137

    Serum N-terminal pro b-type natriuretic peptide (NT-pro-BNP) testing is recommended in the patients with heart failure (HF). We hypothesized that NT-pro-BNP, in combination with other clinical factors in terms of a novel NT-pro BNP-based score, may provide even better predictive power for in-hospital mortality among patients with HF. A retrospective study enrolled adult patients with hospitalization-requiring HF who fulfilled the predefined criteria during the period from January 2011 to December 2013. We proposed a novel scoring system consisting of several independent predictors including NT-pro-BNP for predicting in-hospital mortality, and then compared the prognosis-predictive power of the novel NT-pro BNP-based score with other prognosis-predictive scores. A total of 269 patients were enrolled in the current study. Factors such as “serum NT-pro-BNP level above 8100 mg/dl,” “age above 79 years,” “without taking angiotensin converting enzyme inhibitors/angiotensin receptor blocker,” “without taking beta-blocker,” “without taking loop diuretics,” “with mechanical ventilator support,” “with non-invasive ventilator support,” “with vasopressors use,” and “experience of cardio-pulmonary resuscitation” were found as independent predictors. A novel NT-pro BNP-based score composed of these risk factors was proposed with excellent predictability for in-hospital mortality. The proposed novel NT-pro BNP-based score was extremely effective in predicting in-hospital mortality in HF patients. PMID:27411951

    BACKGROUND Risk of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), may be increased in liver cirrhosis. We conducted a single-center study to explore the epidemiology, risk factors, and in-hospital mortality of VTE in Chinese patients with liver cirrhosis. MATERIAL AND METHODS All patients with liver cirrhosis who were consecutively admitted to our hospital between January 2011 and December 2013 were retrospectively included. RESULTS Of 2006 patients with liver cirrhosis included, 9 patients were diagnosed with or developed VTE during hospitalization, including 5 patients with a previous history of DVT, 1 patient with either a previous history of DVT or new onset of PE, and 3 patients with new onset of VTE (PE, n=1; DVT, n=2). Risk factors for VTE included a significantly higher proportion of hypertension and significantly higher red blood cells, hemoglobin, alanine aminotransferase, aspartate aminotransferase, prothrombin time (PT), international normalized ratio (INR), D-dimer, and Child-Pugh scores. The in-hospital mortality was significantly higher in patients with VTE than those without VTE (33.3% [3/9] versus 3.4% [67/1997], P<0.001). CONCLUSIONS VTE was observed in 0.4% of patients with liver cirrhosis during hospitalization and it significantly increased the in-hospital mortality. Elevated PT/INR aggravated the risk of VTE.

    Background Bariatric surgery is an option for sustained weight loss for the morbidly obese patient. In Brazil coexists the Unified Health System (SUS) with universal coverage and from which depend 150 million Brazilians and supplemental health security, predominantly private, with 50 million beneficiaries. Aim To compare access, in-hospital mortality, length of stay and costs for patients undergoing bariatric surgery, assisted in one or another system. Methods Data from DATASUS and IBGE were used for SUS patients' and database from one health plan of southeastern Brazil for the health insurance patients. Results Between 2001 and 2010 there were 24,342 and 4,356 surgeries performed in SUS and in the health insurance company, respectively. The coverage rates for surgeries performed in 2010 were 5.3 and 91/100.000 individuals in SUS and health insurance respectively. The rate of in-hospital mortality in SUS, considering the entire country, was 0.55 %, 0.44 % considering SUS Southeast, and 0.30 % for the health insurance. The costs of surgery in the SUS and in the health insurance trend to equalization over the years. Conclusion Despite differences in access and characteristics that may compromise the outcome of bariatric surgery, patients treated at the Southeast SUS had similar rate of in-hospital mortality compared to the health insurance patients.

    The objective of this study was to analyze the burden of disease due to suicide in Mexico using years of life lost (YLL) between 2000 and 2012 by sex, age group (for those under 85 years of age) and jurisdiction. Vital statistics on mortality and population estimates were used to calculate standardized mortality rates and years of life lost due to suicide. Between 2000 and 2012 a sustained increase in the suicide mortality rate was observed in Mexico. The age group with the highest rate was 85 years of age or older for men, and 15-19 years of age for women. The highest impact in life expectancy due to suicide occurred at 20 to 24 years of age in men and 15 to 19 years of age in women. The states with the highest mortality due to suicide were located in the Yucatan Peninsula (Yucatan, Quintana Roo and Campeche). Mortality due to suicide in Mexico has increased continually. As suicides are preventable, the implementation of health public policies through timely identification, integral prevention strategies and the detailed study of associated risk factors is imperative.

    Objective This study was conducted to estimate the cause-specific mortality in male emergency responders (ER), compare with that of Korean men. Mortality was also compared between more experienced firefighters (i.e., firefighters employed ≥20 years and firefighters employed ≥10 to <20 years) and less experienced firefighters and non-firefighters (i.e., firefighters employed <10 years and non-firefighters) to investigate associations between mortality and exposure to occupational hazards. Methods The cohort was comprised of 33,442 males who were employed as ERs between 1980 and 2007 and not deceased as of 1991. Work history was merged with the death registry from the National Statistical Office of Korea to follow-up on mortality between 1992 and 2007. Standardized mortality ratios (SMR) for ERs were calculated in reference to the Korean male population. Adjusted relative risks (ARRs) of mortalities for firefighters employed ≥20 years and ≥10 years to <20 years were calculated in reference to non-firefighters and firefighters employed < 10 years. Results Overall (SMR=0.43, 95%CI=0.39–0.47) and some kinds of cause-specific mortalities were significantly lower among ERs compared with the Korean male population. No significant increase in mortality was observed across the major ICD-10 classifications among ERs. Mortality due to exposure to smoke, fire, and flames (SMR=3.11, 95% CI=1.87–4.85), however, was significantly increased among ERs. All-cause mortality (ARR=1.46, 95% CI=1.13–1.89), overall cancer mortality (ARR=1.54, 95% CI=1.02–2.31) and mortality of external injury, poisoning and external causes (ARR=3.13, 95% CI=1.80–5.46) were significantly increased among firefighters employed ≥20 years compared to those of non-firefighters and firefighters employed < 10 years. Conclusions An increase in mortality due to all cancer and external injury, poisoning, and external causes in firefighters employed ≥20 years compared with non-firefighters and

    Background Several risk scores were developed for acute coronary syndrome (ACS) patients, but their use is limited by their complexity. Purpose The purpose of this study was to identify predictors at admission for in-hospital mortality in ACS patients in western Romania, using a simple risk-assessment tool – the new Canada acute coronary syndrome (C-ACS) risk score. Patients and methods The baseline risk of patients admitted with ACS was retrospectively assessed using the C-ACS risk score. The score ranged from 0 to 4; 1 point was assigned for the presence of each of the following parameters: age ≥75 years, Killip class >1, systolic blood pressure <100 mmHg, and heart rate >100 bpm. Results A total of 960 patients with ACS were included, 409 (43%) with ST-segment elevation myocardial infarction (STEMI) and 551 (57%) with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). The C-ACS score predicted in-hospital mortality in all ACS patients with a C-statistic of 0.95 (95% CI: 0.93–0.96), in STEMI patients with a C-statistic of 0.92 (95% confidence interval [CI]: 0.89–0.94), and in NSTE-ACS patients with a C-statistic of 0.97 (95% CI: 0.95–0.98). Of the 960 patients, 218 (22.7%) were aged ≥75 years. The proportion of patients aged ≥75 years was 21.7% in the STEMI subgroup and 23.4% in the NSTE-ACS subgroup (P>0.05). Age ≥75 years was significantly associated with in-hospital mortality in ACS patients (odds ratio [OR]: 3.25, 95% CI: 1.24–8.25) and in the STEMI subgroup (OR >3.99, 95% CI: 1.28–12.44). Female sex was strongly associated with mortality in the NSTE-ACS subgroup (OR: 27.72, 95% CI: 1.83–39.99). Conclusion We conclude that C-ACS score was the strongest predictor of in-hospital mortality in all ACS patients while age ≥75 years predicted the mortality well in the STEMI subgroup. PMID:27217732

    Background Foundry work is associated with serious occupational hazards. Although several studies have investigated the health risks associated with foundry work, the results of these studies have been inconsistent with the exception of an increased lung cancer risk. The current study evaluated the mortality of Korean foundry workers due to malignant and non-malignant diseases. Methods This study is part of an ongoing investigation of Korean foundry workers. To date, we have observed more than 150,000 person-years in male foundry production workers. In the current study, we stratified mortality ratios by the following job categories: melting-pouring, molding-coremaking, fettling, and uncategorized production work. We calculated standard mortality ratios (SMR) of foundry workers compare to general Korean men and relative risk (RR) of mortality of foundry production workers reference to non-production worker, respectively. Results Korean foundry production workers had a significantly higher risk of mortality due to malignant disease, including stomach (RR: 3.96; 95% CI: 1.41–11.06) and lung cancer (RR: 2.08; 95% CI: 1.01–4.30), compared with non-production workers. High mortality ratios were also observed for non-malignant diseases, including diseases of the circulatory (RR: 1.92; 95% CI: 1.18–3.14), respiratory (RR: 1.71; 95% CI: 1.52–21.42 for uncategorized production worker), and digestive (RR: 2.27; 95% CI: 1.22–4.24) systems, as well as for injuries (RR: 2.36; 95% CI: 1.52–3.66) including suicide (RR: 3.64; 95% CI: 1.32–10.01). Conclusion This study suggests that foundry production work significantly increases the risk of mortality due to some kinds of malignant and non-malignant diseases compared with non-production work.

    Understanding the effects of global climate change from both environmental and human health perspectives has gained great importance. Particularly, studies on the direct effect of temperature increase on future mortality have been conducted. However, few of those studies considered population changes, and although the world population is rapidly aging, no previous study considered the effect of society aging. Here we present a projection of future temperature-related mortality due to both climate and demographic changes in seven major cities of South Korea, a fast aging country, until 2100; we used the HadGEM3-RA model under four Representative Concentration Pathway (RCP) scenarios (RCP 2.6, 4.5, 6.0, and 8.5) and the United Nations world population prospects under three fertility scenarios (high, medium, and low). The results showed markedly increased mortality in the elderly group, significantly increasing the overall future mortality. In 2090s, South Korea could experience a four- to six-time increase in temperature-related mortality compared to that during 1992-2010 under four different RCP scenarios and three different fertility variants, while the mortality is estimated to increase only by 0.5 to 1.5 times assuming no population aging. Therefore, not considering population aging may significantly underestimate temperature risks. PMID:27316627

    Background: In this study, we examined the epidemiological aspects of neonatal mortality due to intrauterine infections with regard to regional characteristics. Methods: Consolidated report of the Ministry of Health and Social Development of the Republic of Kazakhstan on children deceased during their first 28 days of life due to intrauterine infections (P23 – congenital pneumonia, P35–39 – infectious diseases specific to the perinatal period) in the country and its regions for 2010 – 2014 was used in this investigation. Descriptive and analytical methods of medical statistics and epidemiology were used as the main method of this 5-year (2010–2014) retrospective study. Results: Overall, 3,298 neonatal deaths from intrauterine infections were recorded in Kazakhstan during the period of 2010–2014, 1,925 of which were early and 1,373 were late neonatal deaths. The average annual rate of neonatal mortality rate from intrauterine infection in the country amounted to 1.73±0.23‰ (95% CI=1.27–2.19‰), whereas trends during the study period decreased (T=−15.3%). Regional characteristics of neonatal mortality were established. Different levels for cartograms of neonatal mortality from intrauterine infections were defined: low (up to 1.28‰), average (from 1.28‰ to 2.12‰) and high (by 2.12‰ and above). Neonatal mortality in the early and late periods was also analyzed. Conclusion: This is the first epidemiological study of neonatal mortality from intrauterine infection, which contains a detailed space-time evaluation. The results of this investigation can be used to improve the state program to combat infant mortality. PMID:26576344

    OBJECTIVE Hyperglycemia may increase mortality in patients who receive total parenteral nutrition (TPN). However, this has not been well studied in noncritically ill patients (i.e., patients in the nonintensive care unit setting). The aim of this study was to determine whether mean blood glucose level during TPN infusion is associated with increased mortality in noncritically ill hospitalized patients. RESEARCH DESIGN AND METHODS This prospective multicenter study involved 19 Spanish hospitals. Noncritically ill patients who were prescribed TPN were included prospectively, and data were collected on demographic, clinical, and laboratory variables as well as on in-hospital mortality. RESULTS The study included 605 patients (mean age 63.2 ± 15.7 years). The daily mean TPN values were 1.630 ± 323 kcal, 3.2 ± 0.7 g carbohydrates/kg, 1.26 ± 0.3 g amino acids/kg, and 0.9 ± 0.2 g lipids/kg. Multiple logistic regression analysis showed that the patients who had mean blood glucose levels >180 mg/dL during the TPN infusion had a risk of mortality that was 5.6 times greater than those with mean blood glucose levels <140 mg/dL (95% CI 1.47–21.4 mg/dL) after adjusting for age, sex, nutritional state, presence of diabetes or hyperglycemia before starting TPN, diagnosis, prior comorbidity, carbohydrates infused, use of steroid therapy, SD of blood glucose level, insulin units supplied, infectious complications, albumin, C-reactive protein, and HbA1c levels. CONCLUSIONS Hyperglycemia (mean blood glucose level >180 mg/dL) in noncritically ill patients who receive TPN is associated with a higher risk of in-hospital mortality. PMID:23223407

    Introduction Despite significant progress in improving access to antiretroviral therapy over the past decade, substantial numbers of people living with HIV (PLHIV) in all regions continue to experience severe illness and require hospitalization. We undertook a global review assessing the proportion of hospitalizations and in-hospital deaths because of tuberculosis (TB) in PLHIV. Methods Seven databases were searched to identify studies reporting causes of hospitalizations among PLHIV from 1 January 2007 to 31 January 2015 irrespective of age, geographical region or language. The proportion of hospitalizations and in-hospital mortality attributable to TB was estimated using random effects meta-analysis. Results From an initial screen of 9049 records, 66 studies were identified, providing data on 35,845 adults and 2792 children across 42 countries. Overall, 17.7% (95% CI 16.0 to 20.2%) of all adult hospitalizations were because of TB, making it the leading cause of hospitalization overall; the proportion of adult hospitalizations because of TB exceeded 10% in all regions except the European region. Of all paediatric hospitalizations, 10.8% (95% CI 7.6 to 13.9%) were because of TB. There was insufficient data among children for analysis by region. In-hospital mortality attributable to TB was 24.9% (95% CI 19.0 to 30.8%) among adults and 30.1% (95% CI 11.2 to 48.9%) among children. Discussion TB remains a leading cause of hospitalization and in-hospital death among adults and children living with HIV worldwide. PMID:26765347

    Aims Although acute venous thrombo-embolism (VTE) often afflicts patients with advanced age, the predictors of in-hospital mortality for elderly VTE patients are unknown. Methods and results Among 1247 consecutive patients with acute VTE from the prospective SWIss Venous ThromboEmbolism Registry (SWIVTER), 644 (52%) were elderly (≥65 years of age). In comparison to younger patients, the elderly more often had pulmonary embolism (PE) (60 vs. 42%; P< 0.001), cancer (30 vs. 20%; P< 0.001), chronic lung disease (14 vs. 8%; P= 0.001), and congestive heart failure (12 vs. 2%; P< 0.001). Elderly VTE patients were more often hospitalized (75 vs. 52%; P< 0.001), and there was no difference in the use of thrombolysis, catheter intervention, or surgical embolectomy between the elderly and younger PE patients (5 vs. 6%; P= 0.54), despite a trend towards a higher rate of massive PE in the elderly (8 vs. 4%; P= 0.07). The overall in-hospital mortality rate was 6.6% in the elderly vs. 3.2% in the younger VTE patients (P= 0.033). Cancer was associated with in-hospital death both in the elderly [hazard ratio (HR) 4.91, 95% confidence interval (CI) 2.32–10.38; P< 0.001] and in the younger patients (HR 4.90, 95% CI 1.37–17.59; P= 0.015); massive PE was a predictor of in-hospital death in the elderly only (HR 3.77, 95% CI 1.63–8.74; P= 0.002). Conclusion Elderly patients had more serious VTE than younger patients, and massive PE was particularly life-threatening in the elderly. PMID:22036872

    Background Maternal smoking is associated with infant respiratory infections and with increased risk of low birthweight (LBW) infants and preterm birth. This study assesses the association of maternal smoking during pregnancy with both respiratory and non-respiratory infectious disease (ID) morbidity and mortality in infants. Methods We conducted two retrospective case-control analyses of infants born in Washington State from 1987–2004 using linked birth certificate, death certificate, and hospital discharge records. One assessed morbidity—infants hospitalized due to ID within one year of birth (47,404 cases/48,233 controls). The second assessed mortality—infants who died within one year due to ID (627 cases/2,730 controls). Results Maternal smoking was associated with both hospitalization (Adjusted Odds Ratio (AOR)=1.52; 95%CI: 1.46, 1.58) and mortality (AOR=1.51; 95%CI: 1.17, 1.96) due to any ID. In subgroup analyses, maternal smoking was associated with hospitalization due to a broad range of ID including both respiratory (AOR=1.69; 95%CI: 1.63, 1.76) and non-respiratory ID (AOR=1.27; 95%CI: 1.20, 1.34). Further stratification by birthweight and gestational age did not appreciably change these estimates. In contrast, there was no association of maternal smoking with ID infant mortality when only LBW infants were considered. Conclusions Maternal smoking was associated with a broad range of both respiratory and non-respiratory ID outcomes. Despite attenuation of the mortality association among LBW infants, ID hospitalization was found to be independent of both birthweight and gestational age. These findings suggest that full-term infants of normal weight whose mothers smoked may suffer an increased risk of serious ID morbidity and mortality. PMID:22929173

    Mortality from cerebrospinal parelaphostrongylosis caused by the meningeal worm (Parelaphostrongylus tenuis) has been hypothesized to limit elk (Cervus elaphus nelsoni) populations in areas where elk are conspecific with white-tailed deer (Odocoileus virginianus). Elk were reintroduced into Michigan (USA) in the early 1900s and subsequently greatly increased population size and distribution despite sympatric high-density (???12/km2) white-tailed deer populations. We monitored 100 radio-collared elk of all age and sex classes from 1981-94, during which time we documented 76 mortalities. Meningeal worm was a minor mortality factor for elk in Michigan and accounted for only 3% of mortalities, fewer than legal harvest (58%), illegal kills (22%), other diseases (7%), and malnutrition (4%). Across years, annual cause-specific mortality rates due to cerebrospinal parelaphostrongylosis were 0.033 (SE=0.006), 0.029 (SE=0.005), 0.000 (SE=0.001), and 0.000 (SE=0.000) for calves, 1-yr-old, 2-yr-old, and ???3-yr-old, respectively. The overall population-level mortality rate due to cerebrospinal parelaphostrongylosis was 0.009 (SE=0.001). Thus, meningeal worm had little impact on elk in Michigan during our study despite greater than normal precipitation (favoring gastropods) and record (???14 km2) deer densities. Further, elk in Michigan have shown sustained population rates-of-increase of ???18%/yr and among the highest levels of juvenile production and survival recorded for elk in North America, indicating that elk can persist in areas with meningeal worm at high levels of population productivity. it is likely that local ecologic characteristics among elk, white-tailed deer, and gastropods, and degree of exposure, age of elk, individual and population experience with meningeal worm, overall population vigor, and moisture determine the effects of meningeal worm on elk populations. ??

    This bottom-up modeling study, supported by new population census 2011 data, simulates ozone (O3) and fine particulate matter (PM2.5) exposure on local to regional scales. It quantifies, present-day premature mortalities associated with the exposure to near-surface PM2.5 and O3 concentrations in India using a regional chemistry model. We estimate that PM2.5 exposure leads to about 570,000 (CI95: 320,000-730,000) premature mortalities in 2011. On a national scale, our estimate of mortality by chronic obstructive pulmonary disease (COPD) due to O3 exposure is about 12,000 people. The Indo-Gangetic region accounts for a large part (~42%) of the estimated mortalities. The associated lost life expectancy is calculated as 3.4 ± 1.1 years for all of India with highest values found for Delhi (6.3 ± 2.2 years). The economic cost of estimated premature mortalities associated with PM2.5 and O3 exposure is about 640 (350-800) billion USD in 2011, which is a factor of 10 higher than total expenditure on health by public and private expenditure.

    Type A acute aortic dissection is a life-threatening vascular emergency because of its high morbidity and mortality. Platelet is a pivotal ingredient involved in the development of acute aortic dissection. In this study, we aimed to investigate whether mean platelet volume (MPV)/platelet count ratio predicts in-hospital complications and long-term mortality in type A acute aortic dissection. In this single-center and prospective cohort study, 106 consecutive patients with Stanford type A acute aortic dissection admitted to the hospital within 12 h after onset were recruited. The best cut-off value of MPV/platelet count ratio predicting all-cause mortality was determined by the receiver operator characteristic analysis. Patients were divided into high (H-MPV/platelet count) and low (L-MPV/platelet count) groups based on the cut-off value of 7.49 (10 fl/10/l). Patients were followed up for 3.5 years. Of the 106 acute aortic dissection patients, 71 (67.0%) died during the study period, with a median follow-up duration of 570 days. Compared to the L-MPV/platelet count group, patients with H-MPV/platelet count had a higher risk of in-hospital complications including hypotension, hypoxemia, myocardial ischemia/infarction, conscious disturbance, pericardial tamponade, paraplegia, and poor survival (all P < 0.05). In multivariable Cox regression models adjusted for potential confounders, MPV/platelet count ratio was positively associated with the hazard of all-cause mortality, irrespective of interventions either with medication only or urgent surgery, and the hazard ratios were 2.81 (95% confidence interval 1.28-4.48) for the H-MPV/platelet count group when taking L-MPV/platelet count group as the reference (P = 0.005). The MPV/platelet count ratio was a strong independent predictor for in-hospital complications and long-term mortality in patients with type A acute aortic dissection. PMID:26575495

  11. Revised trauma scoring system to predict in-hospital mortality in the emergency department: Glasgow Coma Scale, Age, and Systolic Blood Pressure score

    PubMed Central

    2011-01-01

    Introduction Our aim in this study was to assess whether the new Glasgow Coma Scale, Age, and Systolic Blood Pressure (GAP) scoring system, which is a modification of the Mechanism, Glasgow Coma Scale, Age, and Arterial Pressure (MGAP) scoring system, better predicts in-hospital mortality and can be applied more easily than previous trauma scores among trauma patients in the emergency department (ED). Methods This multicenter, prospective, observational study was conducted to analyze readily available variables in the ED, which are associated with mortality rates among trauma patients. The data used in this study were derived from the Japan Trauma Data Bank (JTDB), which consists of 114 major emergency hospitals in Japan. A total of 35,732 trauma patients in the JTDB from 2004 to 2009 who were 15 years of age or older were eligible for inclusion in the study. Of these patients, 27,154 (76%) with complete sets of important data (patient age, Glasgow Coma Scale (GCS) score, systolic blood pressure (SBP), respiratory rate and Injury Severity Score (ISS)) were included in our analysis. We calculated weight for the predictors of the GAP scores on the basis of the records of 13,463 trauma patients in a derivation data set determined by using logistic regression. Scores derived from four existing scoring systems (Revised Trauma Score, Triage Revised Trauma Score, Trauma and Injury Severity Score and MGAP score) were calibrated using logistic regression models that fit in the derivation set. The GAP scoring system was compared to the calibrated scoring systems with data from a total of 13,691 patients in a validation data set using c-statistics and reclassification tables with three defined risk groups based on a previous publication: low risk (mortality < 5%), intermediate risk, and high risk (mortality > 50%). Results Calculated GAP scores involved GCS score (from three to fifteen points), patient age < 60 years (three points) and SBP (> 120 mmHg, six points; 60 to 120

    The mortality due to snakebite envenomation in Costa Rica for the period 1993-2006 was investigated by a retrospective analysis. There were 48 fatalities due to snakebites during this period. Mortality rates ranged from 0.02 per 100,000 population in 2006 to 0.19 per 100,000 population in 1993. Case fatality rates in the period 1993-2000 ranged between 0.18% (2000) and 1.15% (1993). The highest numbers of fatal cases occurred in the provinces of Puntarenas and Limón, in low-land humid regions where the species Bothrops asper ('terciopelo') is distributed and agricultural activities predominate. The most affected age groups were those of 20-29, 40-49 and 50-59 years, and fatal cases predominated in males over females by a ratio of 5:1. PMID:18625261

    Background Hypocalcemia is a frequent abnormality that has been associated with disease severity and outcome in hospitalized foals. However, the pathogenesis of equine neonatal hypocalcemia is poorly understood. Hypovitaminosis D in critically ill people has been linked to hypocalcemia and mortality; however, information on vitamin D metabolites and their association with clinical findings and outcome in critically ill foals is lacking. The goal of this study was to determine the prevalence of vitamin D deficiency (hypovitaminosis D) and its association with serum calcium, phosphorus, and parathyroid hormone (PTH) concentrations, disease severity, and mortality in hospitalized newborn foals. Methods and Results One hundred newborn foals ≤72 hours old divided into hospitalized (n = 83; 59 septic, 24 sick non-septic [SNS]) and healthy (n = 17) groups were included. Blood samples were collected on admission to measure serum 25-hydroxyvitamin D3 [25(OH)D3], 1,25-dihydroxyvitamin D3 [1,25(OH) 2D3], and PTH concentrations. Data were analyzed by nonparametric methods and univariate logistic regression. The prevalence of hypovitaminosis D [defined as 25(OH)D3 <9.51 ng/mL] was 63% for hospitalized, 64% for septic, and 63% for SNS foals. Serum 25(OH)D3 and 1,25(OH) 2D3 concentrations were significantly lower in septic and SNS compared to healthy foals (P<0.0001; P = 0.037). Septic foals had significantly lower calcium and higher phosphorus and PTH concentrations than healthy and SNS foals (P<0.05). In hospitalized and septic foals, low 1,25(OH)2D3 concentrations were associated with increased PTH but not with calcium or phosphorus concentrations. Septic foals with 25(OH)D3 <9.51 ng/mL and 1,25(OH) 2D3 <7.09 pmol/L were more likely to die (OR=3.62; 95% CI = 1.1-12.40; OR = 5.41; 95% CI = 1.19-24.52, respectively). Conclusions Low 25(OH)D3 and 1,25(OH)2D3 concentrations are associated with disease severity and mortality in hospitalized foals. Vitamin D deficiency may

    Global temperature rise and extremes accompanying drought threaten forests and their associated climatic feedbacks. Our ability to accurately simulate drought-induced forest impacts remains highly uncertain in part owing to our failure to integrate physiological measurements, regional-scale models, and dynamic global vegetation models (DGVMs). Here we show consistent predictions of widespread mortality of needleleaf evergreen trees (NET) within Southwest USA by 2100 using state-of-the-art models evaluated against empirical data sets. Experimentally, dominant Southwest USA NET species died when they fell below predawn water potential (Ψpd) thresholds (April–August mean) beyond which photosynthesis, hydraulic and stomatal conductance, and carbohydrate availability approached zero. The evaluated regional models accurately predicted NET Ψpd, and 91% of predictions (10 out of 11) exceeded mortality thresholds within the twenty-first century due to temperature rise. The independent DGVMs predicted ≥50% loss of Northern Hemisphere NET by 2100, consistent with the NET findings for Southwest USA. Notably, the global models underestimated future mortality within Southwest USA, highlighting that predictions of future mortality within global models may be underestimates. Taken together, the validated regional predictions and the global simulations predict widespread conifer loss in coming decades under projected global warming.

    Introduction: The purpose of measuring the burden of disease involves aggregating morbidity and mortality components into a single indicator, the disability-adjusted life year (DALY), to measure how much and how people live and suffer the impact of a disease. Objective: To estimate the global burden of disease due to AIDS in a municipality of southern Brazil. Methods: An ecological study was conducted in 2009 to examine the incidence and AIDS-related deaths among the population residing in the city of Tubarao, Santa Catarina State, Brazil. Data from the Mortality Information System in the National Health System was used to calculate the years of life lost (YLL) due to premature mortality. The calculation was based on the difference between a standardized life expectancy and age at death, with a discount rate of 3% per year. Data from the Information System for Notifiable Diseases were used to calculate the years lived with disability (YLD). The DALY was estimated by the sum of YLL and YLD. Indicator rates were estimated per 100,000 inhabitants, distributed by age and gender. Results: A total of 131 records were examined, and a 572.5 DALYs were estimated, which generated a rate of 593.1 DALYs/100,000 inhabitants. The rate among men amounted to 780.7 DALYs/100,000, whereas among women the rate was 417.1 DALYs/100,000. The most affected age groups were 30-44 years for men and 60-69 years for women. Conclusion: The burden of disease due to AIDS in the city of Tubarao was relatively high when considering the global trend. The mortality component accounted for more than 90% of the burden of disease. PMID:26603227

    Abstract Background: Observational studies have suggested that vitamin B supplementation is associated with cancer risk, but this association remains controversial. A pooled data-based meta-analysis was conducted to summarize the evidence from randomized controlled trials (RCTs) investigating the effects of vitamin B supplementation on cancer incidence, death due to cancer, and total mortality. Methods: PubMed, EmBase, and the Cochrane Library databases were searched to identify trials to fit our analysis through August 2015. Relative risk (RR) was used to measure the effect of vitamin B supplementation on the risk of cancer incidence, death due to cancer, and total mortality using a random-effect model. Cumulative meta-analysis, sensitivity analysis, subgroup analysis, heterogeneity tests, and tests for publication bias were also conducted. Results: Eighteen RCTs reporting the data on 74,498 individuals were included in the meta-analysis. Sixteen of these trials included 4103 cases of cancer; in 6 trials, 731 cancer-related deaths occurred; and in 15 trials, 7046 deaths occurred. Vitamin B supplementation had little or no effect on the incidence of cancer (RR: 1.04; 95% confidence interval [CI]: 0.98–1.10; P = 0.216), death due to cancer (RR, 1.05; 95% CI: 0.90–1.22; P = 0.521), and total mortality (RR, 1.00; 95% CI: 0.94–1.06; P = 0.952). Upon performing a cumulative meta-analysis for cancer incidence, death due to cancer, and total mortality, the nonsignificance of the effect of vitamin B persisted. With respect to specific types of cancer, vitamin B supplementation significantly reduced the risk of skin melanoma (RR, 0.47; 95% CI: 0.23–0.94; P = 0.032). Conclusion: Vitamin B supplementation does not have an effect on cancer incidence, death due to cancer, or total mortality. It is associated with a lower risk of skin melanoma, but has no effect on other cancers. PMID:27495015

    This study examined deaths due to unintentional injuries among children in Japan to identify the age groups and sexes at most risk, and the types of injuries, so that effective forms of targeted intervention can be devised. Among children aged 0–14 years, deaths whose underlying causes had been classified under code V01-X59 of the ICD-10 were defined as deaths of children caused by unintentional injuries. Using data from the Vital Statistics 2000–2009 for analysis, we examined the changes in mortality and trends in terms of sex, age, and cause of death. Mortality decreased by 46.2%, from 933 in 2000 to 502 in 2009. The mortality rate among children aged 1–4 years decreased by almost half. The total number of deaths during this decade was 7,362 (boys: 4,690, girls: 2,672). Among the causes of death, the majority were due to “transport accidents”, followed by “other accidental threats to breathing”, and “accidental drowning and submersion”. The characteristics observed in terms of sex, age, and cause of death—that is, deaths from suffocation among infants aged less than 1 year, drowning deaths among boys, and transport accidents involving pedestrians and cyclists—must be addressed as targets for future intervention.

    Background Respiratory manifestations of HIV disease differ globally due to differences in current availability of effective highly active antiretroviral therapy (HAART) programs and epidemiology of infectious diseases. Objective To describe the association between HAART and discharge diagnosis and all-cause in-hospital mortality among hospitalized patients with infectious respiratory disease and HIV/AIDS. Material and Methods We retrospectively reviewed the records of patients hospitalized at a specialty hospital for respiratory diseases in Mexico City between January 1st, 2010 and December 31st, 2011. We included patients whose discharge diagnosis included HIV or AIDS and at least one infectious respiratory diagnosis. The information source was the clinical chart. We analyzed the association between HAART for 180 days or more and type of respiratory disease using polytomous logistic regression and all-cause hospital mortality by multiple logistic regressions. Results We studied 308 patients, of whom 206 (66.9%) had been diagnosed with HIV infection before admission to the hospital. The CD4+ lymphocyte median count was 68 cells/mm3 [interquartile range (IQR): 30–150]. Seventy-five (24.4%) cases had received HAART for more than 180 days. Pneumocystis jirovecii pneumonia (PJP) (n = 142), tuberculosis (n = 63), and bacterial community-acquired pneumonia (n = 60) were the most frequent discharge diagnoses. Receiving HAART for more than 180 days was associated with a lower probability of PJP [Adjusted odd ratio (aOR): 0.245, 95% Confidence Interval (CI): 0.08–0.8, p = 0.02], adjusted for sociodemographic and clinical covariates. HAART was independently associated with reduced odds (aOR 0.214, 95% CI 0.06–0.75) of all-cause in-hospital mortality, adjusting for HIV diagnosis previous to hospitalization, age, access to social security, low socioeconomic level, CD4 cell count, viral load, and discharge diagnoses. Conclusions HAART for 180 days or more was associated

International Classification of Disease, 10th Revision, coded discharge diagnoses were collected from consecutive admissions for 2003-2005 from a public tertiary care hospital. Mortality data were not coded. Perinatal disease was the most common cause of mortality, with hyaline membrane disease the primary cause. Younger children, particularly males, are disproportionately affected by all indicator diseases (P < 0.001) and more likely to die from acute respiratory tract infections and infectious diseases (P < 0.05). Sickle cell disease was the fourth most common diagnosis. Children in western Jamaica are most affected by diseases of prematurity. These children experience disease burden similar to that of children in other developing countries, but fewer neonatal sepsis and insect-borne infections, and more hematologic illness. PMID:19346383

    Abstract To investigate the frequency and the spectrum of major opportunistic infections (OIs), evaluate the major clinical factors associated with each specific OI, and identify the risk factors for in-hospital death among HIV patients in East China. A retrospective cohort study was made including all the HIV-infected patients who were admitted for the first time to the Shanghai Public Health Clinical Center during June 1, 2013 to June 1, 2015. The demographic and clinical data were collected. Comparison of continuous variables was analyzed by one-way ANOVA and rank sum test. Person χ2 test and Fisher exact test were applied to analyze the categorical variables. A Cox proportional hazards regression model was used to determine the risk for the occurrence of in-hospital death. In total, 920 patients were enrolled with age of 41.59 ± 13.36 years and 91% male. Median CD4 was 34 (IQR, 13–94) cells/μL. Among these patients, 94.7% acquired OIs while the rest developed malignancies. Pneumocystis pneumonia and bacterial coinfection (42.1%) was found to be the most common OIs, followed by tuberculosis (31.4%), CMV (20.9%), Cryptococcosis (9.0%), and MAC infection (5.2%). Of the above 5 major OIs, CMV-infected patients had the lowest median CD4 cell count 22.50 (IQR, 7.50–82.00) while the patients with tuberculosis infection had the highest count 61.00 (IQR, 27.00–176.00). In-hospital death rate was 4.2 per 100 person-years among these patients. Of note, admitted patients with 2 types of OIs (2.20, 95% CI 1.39–3.48) and those patients who were 40-year old or older (1.75, 95% CI 1.10–2.78) had a higher risk of such death. Pneumocystis pneumonia and tuberculosis were still the leading causes for the admission of HIV-infected patients in East China, and these patients tended to have very low CD4 cell counts. It is believed that expanding the HIV screening test and pushing the infected ones get ART earlier is required for generating a more successful HIV management

    The emergency department (ED) is now the primary source for hospitalizations in the United States, and admission rates for all causes differ widely between EDs. In this study we used a national sample of ED visits to examine variation in risk-standardized hospital admission rates from EDs and the relationship of this variation to inpatient mortality for the fifteen most commonly admitted medical and surgical conditions. We then estimated the impact of variation on national health expenditures under different utilization scenarios. Risk-standardized admission rates differed substantially across EDs, ranging from 1.03-fold for sepsis to 6.55-fold for chest pain between the twenty-fifth and seventy-fifth percentiles of the visits. Conditions such as chest pain, soft tissue infection, asthma, chronic obstructive pulmonary disease, and urinary tract infection were low-mortality conditions that showed the greatest variation. This suggests that some of these admissions might not be necessary, thus representing opportunities to improve efficiency and reduce health spending. Our data indicate that there may be sizeable savings to US payers if differences in ED hospitalization practices could be narrowed among a few of these high-variation, low-mortality conditions.

    Background Compared with open oesophagectomy (OE), minimally invasive oesophagectomy (MIO) proves to have benefits in reducing the risk of pulmonary complications for patients with resectable oesophageal cancer. However, it is unknown whether MIO has superiority in reducing the occurrence of in-hospital mortality (IHM). Objective The objective of this meta-analysis was to explore the effect of MIO vs. OE on the occurrence of in-hospital mortality (IHM). Data Sources Sources such as Medline (through December 31, 2014), Embase (through December 31, 2014), Wiley Online Library (through December 31, 2014), and the Cochrane Library (through December 31, 2014) were searched. Study Selection Data of randomized and non-randomized clinical trials related to MIO versus OE were included. Interventions Eligible studies were those that reported patients who underwent MIO procedure. The control group included patients undergoing conventional OE. Study Appraisal and Synthesis Methods Fixed or random -effects models were used to calculate summary odds ratios (ORs) or relative risks (RRs) for quantification of associations. Heterogeneity among studies was evaluated by using Cochran’s Q and I2 statistics. Results A total of 48 studies involving 14,311 cases of resectable oesophageal cancer were included in the meta-analysis. Compared to patients undergoing OE, patients undergoing MIO had statistically reduced occurrence of IHM (OR=0.69, 95%CI =0.55 -0.86). Patients undergoing MIO also had significantly reduced incidence of pulmonary complications (PCs) (RR=0.73, 95%CI = 0.63-0.86), pulmonary embolism (PE) (OR=0.71, 95%CI= 0.51-0.99) and arrhythmia (OR=0.79, 95%CI = 0.68-0.92). Non-significant reductions were observed among the included studies in the occurrence of anastomotic leak (AL) (OR=0.93, 95%CI =0.78-1.11), or Gastric Tip Necrosis (GTN) (OR=0.89, 95%CI =0.54-1.49). Limitation Most of the included studies were non-randomized case-control studies, with a diversity of study

  5. A review of methods for estimating mortality due to parasites in wild fish populations

    Six methods are described for detecting mortality due to parasitic infections in natural fish populations. They are: (a) through autopsies; (b) by determining the frequency of infections known to be eventually lethal; (c) by observing a decrease in the prevalence of a long-lived parasite (or permanent scar from a parasite) with host age; (d) by observing a decrease in the variance/mean ratio for the parasites with host age; (e) by comparing the observed frequency of a combination of two independent events with the calculated probability of their occurrence; and finally (f) by comparing the observed frequency distribution of the parasite, with a projected frequency based on data from lightly infected fish. In this technique, negative binomials are fitted to the data and truncated at various points. Some advantages and disadvantages of the different methods are given, together with examples. The methods do not necessarily provide definitive answers, but they are indicative of whether or not significant parasite-related mortality may be occurring, and in some cases provide an estimate of its probable magnitude in terms of the total host mortality rate.

    Obstetric haemorrhage continues to be a major cause of maternal mortality. Our analysis of records of over a period of 20 years from April 1982 to March 2002 reveals that it was a contributory cause of maternal mortality in 19.9% of cases. The majority of deaths, (65%) had occurred within 24 hours of admission and in 47.5% of cases there was severe anaemia on admission; 17.5% had died due to an atonic PPH, which was the largest category, followed by ruptured uterus (15%), abruptio placenta (15%) and retained placenta (12.5%). Deaths due to obstetric haemorrhage because of a ruptured uterus, retained placenta and abortion have decreased from 22.22% between 1982 and 1987 to zero in the last 5 years and an increase was seen in deaths due to haemorrhage because of gestational trophoblastic neoplasia and ectopic pregnancy, from 1.69% to 4.87%, unclassified haemorrhage 1.96% to 7.31% and placenta praevia from zero between 1982 and 1987 to 4.87% between 1997 and 2002.

    Interactions between climate and land-use change may drive widespread degradation of Amazonian forests. High-intensity fires associated with extreme weather events could accelerate this degradation by abruptly increasing tree mortality, but this process remains poorly understood. Here we present, to our knowledge, the first field-based evidence of a tipping point in Amazon forests due to altered fire regimes. Based on results of a large-scale, long-term experiment with annual and triennial burn regimes (B1yr and B3yr, respectively) in the Amazon, we found abrupt increases in fire-induced tree mortality (226 and 462%) during a severe drought event, when fuel loads and air temperatures were substantially higher and relative humidity was lower than long-term averages. This threshold mortality response had a cascading effect, causing sharp declines in canopy cover (23 and 31%) and aboveground live biomass (12 and 30%) and favoring widespread invasion by flammable grasses across the forest edge area (80 and 63%), where fires were most intense (e.g., 220 and 820 kW ⋅ m(-1)). During the droughts of 2007 and 2010, regional forest fires burned 12 and 5% of southeastern Amazon forests, respectively, compared with <1% in nondrought years. These results show that a few extreme drought events, coupled with forest fragmentation and anthropogenic ignition sources, are already causing widespread fire-induced tree mortality and forest degradation across southeastern Amazon forests. Future projections of vegetation responses to climate change across drier portions of the Amazon require more than simulation of global climate forcing alone and must also include interactions of extreme weather events, fire, and land-use change.

    We investigated the incidence and prognostic value of anemia as well as of the iron status in non-selected patients admitted to an intensive cardiac care unit (ICCU). 392 patients (mean age 70 ± 13.8 years, 43% women), 168 with acute coronary syndromes (ACS), 122 with acute decompensated heart failure, and 102 with other acute cardiac disorders were consecutively, prospectively assessed. The biomarkers of iron status-serum iron concentration (SIC), total iron binding capacity (TIBC), and transferrin saturation (TSAT) together with standard clinical, biochemical and echocardiographic variables-were analyzed. In-hospital mortality was 3.8% (15 patients). The prevalences of anemia (according to WHO criteria), and iron deficiency (ID) were 64 and 63%, respectively. The level of biomarkers of iron status, but not anemia, was lower in patients who died (p < 0.05). Anemia was less frequent in patients with ACS as compared to the remaining ICCU population (p = 0.019). The analysis by logistic regression indicated the highest risk of death for age [odds ratio (OD) 1.38, 95% CI 1.27-1.55], SIC (OR 0.85, 95% CI 0.78-0.94), TIBC (OR 0.95, 95% CI 0.91-0.98), left ventricle ejection fraction (OR 0.85, 95% CI 0.77-0.93), as well as hospitalization for non-ACS (OR 0.25, 95% CI 0.14-0.46), (p < 0.05). The risk of death during hospitalization tended to increase with decreasing levels of TIBC (p = 0.49), as well as with the absence of ACS (p = 0.54). The incidence of anemia and ID in heterogeneous ICCU patients is high. Parameters of the iron status, but not anemia per se, independently influence in-hospital mortality. The prevalence of anemia is higher in non-ACS patients, and tends to worsen the prognosis. PMID:25502592

    There are few data regarding outcomes from severe sepsis for HIV-infected patients living in rural or semi-rural settings. We aim to describe the characteristics and predictors of mortality in HIV-infected patients admitted with severe sepsis to the University of Virginia located in semi-rural Charlottesville, Virginia, USA. We queried the University of Virginia Clinical Data Repository for cases with ICD-9 codes that included: (1) infection, (2) acute organ dysfunction, and (3) HIV infection. We reviewed each case to confirm the presence of HIV infection and severe sepsis. We recorded socio-demographic, clinical, and laboratory data. We used a generalised linear mixed-effects model to assess pre-specified predictors of mortality. We identified 74 cases of severe sepsis in HIV-infected patients admitted to University of Virginia since 2001. The median (IQR) age was 44 (36-49), 32 (43%) were women, and 56 (76%) were from ethnic minorities. The median (IQR) CD4+ T-cell count was 81 (7-281) cells/µL. In-hospital mortality was 20%. When adjusted for severity of illness and respiratory failure, patients who lived >40 miles away from care or had a CD4+ T cell count <50 cells/µL had > four-fold increased risk of death compared to the rest of the study population (AOR = 4.18, 95% CI: 1.09-16.07, p = 0.037; AOR = 4.33, 95% CI: 1.15-16.29, p = 0.03). In HIV-infected patients from rural and semi-rural Virginia with severe sepsis, mortality was increased in those that lived far from University of Virginia or had a low CD4+ T cell counts. Our data suggest that rural HIV-infected patients may have limited access to care, which predisposes them to critical illness and a high associated mortality. PMID:25931237

    Objective This study aimed to characterize premature mortality among people diagnosed with HIV infection from 2000 to 2009 in Florida, by sex and race/ethnicity, to estimate differences in premature mortality that could be prevented by linkage to HIV care and treatment. Methods Florida surveillance data for HIV diagnoses (excluding concurrent AIDS diagnoses) were linked with vital records data to ascertain deaths through 2011. Years of potential life lost (YPLL) were obtained from the expected number of remaining years of life at a given age from the U.S. sex-specific period life tables. Results Among 41,565 people diagnosed with HIV infection during the study period, 5,249 died, and 2,563 (48.8%) deaths were due to HIV/AIDS. Age-standardized YPLL (aYPLL) due to HIV/AIDS per 1,000 person-years was significantly higher for females than males (372.6, 95% confidence interval [CI] 349.8, 396.2 vs. 295.2, 95% CI 278.4, 312.5); for non-Hispanic black (NHB) females than non-Hispanic white (NHW) and Hispanic females (388.2, 95% CI 360.7, 416.9; 294.3, 95% CI 239.8, 354.9; and 295.0, 95% CI 242.9, 352.5, respectively); and for NHB males compared with NHW and Hispanic males (378.7, 95% CI 353.7, 404.7; 210.6, 95% CI 174.3, 250.8; and 240.9, 95% CI 204.8, 280.2, respectively). In multilevel modeling controlling for individual factors, NHB race was associated with YPLL due to HIV/AIDS for women (p=0.04) and men (p<0.001). Conclusion Among people diagnosed with HIV infection, females and NHB people had a disproportionately high premature mortality from HIV/AIDS, suggesting the need for enhanced efforts to improve linkage to and retention in care and medication adherence for these groups.

    Household cooking is a significant cause for health and environmental problems in the developing countries. There are more than 3 billion people who use biomass for fuel in cooking stoves in their daily life. These cooking stoves use inadequate ventilation and expose especially women and children to indoor smoke. To reduce problems of the biomass burning, India launched an initiative to provide affordable and clean energy solutions for the poorest households by providing clean next-generation cooking stoves. The improved cooking stoves are expected to improve outdoor air quality and to reduce the climate-active pollutants, thus simultaneously slowing the climate change. Previous research has shown that the emissions of black carbon can be decreased substantially, as much as 90 % by applying better technology in cooking stoves. We have implemented reasonable (50% decrease) and best case (90% decrease) scenarios of the reductions in black and organic carbon due to improved cooking stoves in India into ECHAM-HAMMOZ aerosol-climate model. The global simulations of the scenarios will be used to study how the reductions of emissions in India affect the pollutant concentrations and radiation. The simulated reductions in particulate concentrations will also be used to estimate the decrease in mortality rates. Furthermore, we will study how the emission reductions would affect the global climate and mortality if a similar initiative would be applied in other developing countries.

  13. Airway Tissue Plasminogen Activator Prevents Acute Mortality Due to Lethal Sulfur Mustard Inhalation

    Rationale: Sulfur mustard (SM) is a chemical weapon stockpiled today in volatile regions of the world. SM inhalation causes a life-threatening airway injury characterized by airway obstruction from fibrin casts, which can lead to respiratory failure and death. Mortality in those requiring intubation is more than 80%. No therapy exists to prevent mortality after SM exposure. Our previous work using the less toxic analog of SM, 2-chloroethyl ethyl sulfide, identified tissue plasminogen activator (tPA) an effective rescue therapy for airway cast obstruction (Veress, L. A., Hendry-Hofer, T. B., Loader, J. E., Rioux, J. S., Garlick, R. B., and White, C. W. (2013). Tissue plasminogen activator prevents mortality from sulfur mustard analog-induced airway obstruction. Am. J. Respir. Cell Mol. Biol. 48, 439–447). It is not known if exposure to neat SM vapor, the primary agent used in chemical warfare, will also cause death due to airway casts, and if tPA could be used to improve outcome. Methods: Adult rats were exposed to SM, and when oxygen saturation reached less than 85% (median: 6.5 h), intratracheal tPA or placebo was given under isoflurane anesthesia every 4 h for 48 h. Oxygen saturation, clinical distress, and arterial blood gases were assessed. Microdissection was done to assess airway obstruction by casts. Results: Intratracheal tPA treatment eliminated mortality (0% at 48 h) and greatly improved morbidity after lethal SM inhalation (100% death in controls). tPA normalized SM-associated hypoxemia, hypercarbia, and lactic acidosis, and improved respiratory distress. Moreover, tPA treatment resulted in greatly diminished airway casts, preventing respiratory failure from airway obstruction. Conclusions: tPA given via airway more than 6 h after exposure prevented death from lethal SM inhalation, and normalized oxygenation and ventilation defects, thereby rescuing from respiratory distress and failure. Intra-airway tPA should be considered as a life

    Objective AIMS65 is a score designed to predict in-hospital mortality, length of stay, and costs of gastrointestinal bleeding. Our aims were to revalidate AIMS65 as predictor of inpatient mortality and to compare AIMS65’s performance with that of Glasgow–Blatchford (GBS) and Rockall scores (RS) with regard to mortality, and the secondary outcomes of a composite endpoint of severity, transfusion requirements, rebleeding, delayed (6-month) mortality, and length of stay. Methods The study included 309 patients. Clinical and biochemical data, transfusion requirements, endoscopic, surgical, or radiological treatments, and outcomes for 6 months after admission were collected. Clinical outcomes were in-hospital mortality, delayed mortality, rebleeding, composite endpoint, blood transfusions, and length of stay. Results In receiver-operating characteristic curve analyses, AIMS65, GBS, and RS were similar when predicting inpatient mortality (0.76 vs. 0.78 vs. 0.78). Regarding endoscopic intervention, AIMS65 and GBS were identical (0.62 vs. 0.62). AIMS65 was useless when predicting rebleeding compared to GBS or RS (0.56 vs. 0.70 vs. 0.71). GBS was better at predicting the need for transfusions. No patient with AIMS65 = 0, GBS ≤ 6, or RS ≤ 4 died. Considering the composite endpoint, an AIMS65 of 0 did not exclude high risk patients, but a GBS ≤ 1 or RS ≤ 2 did. The three scores were similar in predicting prolonged in-hospital stay. Delayed mortality was better predicted by AIMS65. Conclusion AIMS65 is comparable to GBS and RS in essential endpoints such as inpatient mortality, the need for endoscopic intervention and length of stay. GBS is a better score predicting rebleeding and the need for transfusion, but AIMS65 shows a better performance predicting delayed mortality.

    Infection with Salmonella spp. has long been recognized in avian wildlife, although its significance in causing avian mortality, and its zoonotic risk, is not well understood. This study evaluates the role of Salmonella spp. in wild bird mortality events in the United States from 1985 through 2004. Analyses were performed to calculate the frequency of these events and the proportional mortality by species, year, month, state, and region. Salmonellosis was a significant contributor to mortality in many species of birds; particularly in passerines, for which 21.5% of all mortality events involved salmonellosis. The proportional mortality averaged a 12% annual increase over the 20-yr period, with seasonal peaks in January and April. Increased salmonellosis-related mortality in New England, Southeastern, and Mountain-Prairie states was identified. Based on the results of this study, salmonellosis can be considered an important zoonotic disease of wild birds. ?? Wildlife Disease Association 2008.

    Synoptic weather and ambient air quality synergistically influence human health. We report the relative risk of mortality from all non-accidental, respiratory-, and cardiovascular-related causes, associated with exposure to four air pollutants, by weather type and season, in 10 major Canadian cities for 1981 through 1999. We conducted this multi-city time-series study using Poisson generalized linear models stratified by season and each of six distinctive synoptic weather types. Statistically significant relationships of mortality due to short-term exposure to carbon monoxide, nitrogen dioxide, sulphur dioxide, and ozone were found, with significant modifications of risk by weather type, season, and mortality cause. In total, 61% of the respiratory-related mortality relative risk estimates were significantly higher than for cardiovascular-related mortality. The combined effect of weather and air pollution is greatest when tropical-type weather is present in the spring or summer. PMID:24355413

    Introduction Measurement of mortality in patients with acute myocardial infarction (AMI), congestive heart failure (CHF) and pneumonia (PN) is a high priority since these are common reasons for hospitalization. However, mortality in patients with inflammatory bowel disease (IBD) that are hospitalized for these common medical conditions is unknown. Methods A retrospective review of the 2005–2011 National Inpatient Sample (NIS), (approximately a 20% sample of discharges from community hospitals) was performed. A dataset for all patients with ICD-9-CM codes for primary diagnosis of acute myocardial infarction, pneumonia or congestive heart failure with a co-diagnosis of IBD, Crohn’s disease (CD) or ulcerative colitis (UC). 1:3 propensity score matching between patients with co-diagnosed disease vs. controls was performed. Continuous variables were compared between IBD and controls. Categorical variables were reported as frequency (percentage) and analyzed by Chi-square tests or Fisher’s exact test for co-diagnosed disease vs. control comparisons. Propensity scores were computed through multivariable logistic regression accounting for demographic and hospital factors. In-hospital mortality between the groups was compared. Results Patients with IBD, CD and UC had improved survival after AMI compared to controls. 94/2280 (4.1%) of patients with IBD and AMI died, compared to 251/5460 (5.5%) of controls, p = 0.01. This represents a 25% improved survival in IBD patients that were hospitalized with AMI. There was a 34% improved survival in patients with CD and AMI. There was a trend toward worsening survival in patients with IBD and CHF. Patients with CD and PN had improved survival compared to controls. 87/3362 (2.59%) patients with CD and PN died, compared to 428/10076 (4.25%) of controls, p < .0001. This represents a 39% improved survival in patients with CD that are hospitalized for PN. Conclusion IBD confers a survival benefit for patients hospitalized with AMI. A

    Background Zinc deficiency is commonly prevalent in children in developing countries and plays a role in decreased immunity and increased risk of infection. Preventive zinc supplementation in healthy children can reduce mortality due to common causes like diarrhea, pneumonia and malaria. The main objective was to determine all-cause mortality and cause-specific mortality and morbidity in children under five in developing countries for preventive zinc supplementation. Data sources/ review methods A literature search was carried out on PubMed, the Cochrane Library and the WHO regional databases to identify RCTs on zinc supplementation for greater than 3 months in children less than 5 years of age in developing countries and its effect on mortality was analyzed. Results The effect of preventive zinc supplementation on mortality was given in eight trials, while cause specific mortality data was given in five of these eight trials. Zinc supplementation alone was associated with a statistically insignificant 9% (RR = 0.91; 95% CI: 0.82, 1.01) reduction in all cause mortality in the intervention group as compared to controls using a random effect model. The impact on diarrhea-specific mortality of zinc alone was a non-significant 18% reduction (RR = 0.82; 95% CI: 0.64, 1.05) and 15% for pneumonia-specific mortality (RR = 0.85; 95% CI: 0.65, 1.11). The incidence of diarrhea showed a 13% reduction with preventive zinc supplementation (RR = 0.87; 95% CI: 0.81, 0.94) and a 19% reduction in pneumonia morbidity (RR = 0.81; 95% CI: 0.73, 0.90). Keeping in mind the direction of effect of zinc supplementation in reducing diarrhea and pneumonia related morbidity and mortality; we considered all the outcomes for selection of effectiveness estimate for inclusion in the LiST model. After application of the CHERG rules with consideration to quality of evidence and rule # 6, we used the most conservative estimates as a surrogate for mortality. We, therefore, conclude that zinc

    West Nile virus (WNV) has affected many thousands of birds since it was first detected in North America in 1999, but the overall impact on wild bird populations is unknown. In mid-August 2002, wildlife rehabilitators and local wildlife officials from multiple states began reporting increasing numbers of sick and dying raptors, mostly red-tailed hawks (Buteo jamaicensis) and great horned owls (Bubo virginianus). Commonly reported clinical signs were nonspecific and included emaciation, lethargy, weakness, inability to perch, fly or stand, and nonresponse to danger. Raptor carcasses from 12 states were received, and diagnostic evaluation of 56 raptors implicated WNV infection in 40 (71%) of these cases. Histologically, nonsuppurative encephalitis and myocarditis were the salient lesions (79% and 61%, respectively). Other causes of death included lead poisoning, trauma, aspergillosis, and Salmonella spp. and Clostridium spp. infections. The reason(s) for the reported increase in raptor mortality due to WNV in 2002 compared with the previous WNV seasons is unclear, and a better understanding of the epizootiology and pathogenesis of the virus in raptor populations is needed.

    Few studies have investigated the chronic obstructive pulmonary disease (COPD) mortality fraction attributable to air pollution and modification by individual characteristics of air pollution effects. We applied distributed lag non-linear models to assess the associations between air pollution and COPD mortality in 2007-2011 in Guangzhou, China, and the total COPD mortality fraction attributable to air pollution was calculated as well. We found that an increase of 10 μg/m(3) in particulate matter with an aerodynamic diameter of 10 μm or less (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NO2) was associated with a 1.58% (95% confidence interval (CI): 0.12-3.06%), 3.45% (95% CI: 1.30-5.66%) and 2.35% (95% CI: 0.42-4.32%) increase of COPD mortality over a lag of 0-15 days, respectively. Greater air pollution effects were observed in the elderly, males and residents with low educational attainment. The results showed 10.91% (95% CI: 1.02-9.58%), 12.71% (95% CI: 5.03-19.85%) and 13.38% (95% CI: 2.67-22.84%) COPD mortality was attributable to current PM10, SO2 and NO2 exposure, respectively. In conclusion, the associations between air pollution and COPD mortality differed by individual characteristics. There were remarkable COPD mortality burdens attributable to air pollution in Guangzhou. PMID:27195597

    Introduction: Preeclampsia is the most important cause of maternal mortality in developing countries. A comprehensive prenatal care program including bio-psychosocial components was developed and introduced at a national level in Colombia. We report on the trends in maternal mortality rates and their related causes before and after implementation of this program. Methods: General and specific maternal mortality rates were monitored for nine years (1998-2006). An interrupted time-series analysis was performed with monthly data on cases of maternal mortality that compared trends and changes in national mortality rates and the impact of these changes attributable to the introduction of a bio-psychosocial model. Multivariate analyses were performed to evaluate correlations between the interventions. Results: Five years after (2002 - 2006) its introduction the general maternal mortality rate was significantly reduced to 23% (OR=0.77, CI 95% 0.71-0.82).The implementation of BPSM also reduced the incidence of preeclampsia in 22% (OR= 0.78, CI 95% 0.67-0.88), as also the labor complications by hemorrhage in 25% (OR=0.75, CI 95% 0.59-0.90) associated with the implementation of red code. The other causes of maternal mortality did not reveal significant changes. Biomedical, nutritional, psychosocial assessments, and other individual interventions in prenatal care were not correlated to maternal mortality (p= 0.112); however, together as a model we observed a significant association (p= 0.042). Conclusions: General maternal mortality was reduced after the implementation of a comprehensive national prenatal care program. Is important the evaluation of this program in others populations.

    Objective To evaluate the association between the in-hospital mortality of patients hospitalized due to respiratory diseases and the availability of intensive care units. Methods This retrospective cohort study evaluated a database from a hospital medicine service involving patients hospitalized due to respiratory non-terminal diseases. Data on clinical characteristics and risk factors associated with mortality, such as Charlson score and length of hospital stay, were collected. The following analyses were performed: univariate analysis with simple stratification using the Mantel Haenszel test, chi squared test, Student’s t test, Mann-Whitney test, and logistic regression. Results Three hundred thirteen patients were selected, including 98 (31.3%) before installation of the intensive care unit and 215 (68.7%) after installation of the intensive care unit. No significant differences in the clinical and anthropometric characteristics or risk factors were observed between the groups. The mortality rate was 18/95 (18.9%) before the installation of the intensive care unit and 21/206 (10.2%) after the installation of the intensive care unit. Logistic regression analysis indicated that the probability of death after the installation of the intensive care unit decreased by 58% (OR: 0.42; 95%CI 0.205 -0.879; p = 0.021). Conclusion Considering the limitations of the study, the results suggest a benefit, with a decrease of one death per every 11 patients treated for respiratory diseases after the installation of an intensive care unit in our hospital. The results corroborate the benefits of the implementation of intensive care units in secondary hospitals. PMID:26465244

    The endemic New Zealand Hector's dolphin is considered the rarest species of marine dolphin with a total abundance of less than 4000. The species is listed as vulnerable because of fisheries-related mortality due to entanglement in set nets. The vulnerability of this species is further increased by its fidelity to local natal ranges and the genetic isolation of regional populations. Here we present evidence, based on 108 contemporary samples and 55 historical samples dating back to 1870, of a significant loss of mitochondrial DNA (mtDNA) diversity in two regional populations of Hector's dolphin. The haplotype diversity (h) was calculated from sequences of a 206 bp fragment in the mtDNA control region, designed to identify 13 out of the 14 known maternal lineages. Over the last 20 years, the North Island population has been reduced from at least three lineages (h = 0.41) to a single lineage (h = 0; p < 0.05). Given its small size, reproductive isolation and reduced genetic diversity, this population is likely to become extinct. The diversity of the East Coast South Island population has declined significantly from h = 0.65 to h = 0.35 (p < 0.05). Based on trend analysis of the mtDNA diversity, we predict that the East Coast population will lose all mtDNA diversity within the next 20 years. This time-series of reduction in genetic variation provides independent evidence of the severity of population decline and habitat contraction resulting from fisheries and perhaps other human activities.

    This article discusses the possible bias in tree-ring time series studies extending from the year of sample collection to a prepollution period. The authors hypothesizes that normal mortality (i.e., mortality not associated with sudden disturbance) can cause reduced tree ring widths in years preceding actual tree death and produce a bias toward smaller and more variable ring widths at the end of the tree-ring time series.

    This paper describes severe mortalities recorded in sharpsnout sea bream Diplodus puntazzo larvae reared in mesocosms. The mortalities were attributed to epitheliocystis infection. The pathology associated with the disease is described using histological techniques. Microscopical examination showed a massive infection of the skin, fins, and oral cavity, with impaired feeding, respiration, and osmoregulation being the most likely cause of death. This is the first report of epitheliocystis disease in sharpsnout sea bream and in fish at such an early developmental stage. PMID:19062753

    Numerous modeling studies indicate that emissions from one continent influence air quality over others. Reducing air pollutant emissions from one continent can therefore benefit air quality and health on multiple continents. Here, we estimate the impacts of the intercontinental transport of ozone (O3) and fine particulate matter (PM2.5) on premature human mortality by using an ensemble of global chemical transport models coordinated by the Task Force on Hemispheric Transport of Air Pollution (TF HTAP). We use simulations of 20% reductions of all anthropogenic emissions from 13 regions (North America, Central America, South America, Europe, Northern Africa, Sub-Saharan Africa, Former Soviet Union, Middle East, East Asia, South Asia, South East Asia, Central Asia, and Australia) to calculate their impact on premature mortality within each region and elsewhere in the world. To better understand the impact of potential control strategies, we also analyze premature mortality for global 20% perturbations from five sectors individually: power and industry, ground transport, forest and savannah fires, residential, and others (shipping, aviation, and agriculture). Following previous studies, premature human mortality resulting from each perturbation scenario is calculated using a health impact function based on a log-linear model for O3 and an integrated exposure response model for PM2.5 to estimate relative risk. The spatial distribution of the exposed population (adults aged 25 and over) is obtained from the LandScan 2011 Global Population Dataset. Baseline mortality rates for chronic respiratory disease, ischemic heart disease, cerebrovascular disease, chronic obstructive pulmonary disease, and lung cancer are estimated from the GBD 2010 country-level mortality dataset for the exposed population. Model results are regridded from each model's original grid to a common 0.5°x0.5° grid used to estimate mortality. We perform uncertainty analysis and evaluate the sensitivity

    This single-centre retrospective cohort study evaluated the incidence and outcome of mycoses in critical ill patients (n = 283) with sepsis due to peritonitis. Overall mortality was 41.3%, and the 28-day mortality was 29.3%. Fungal pathogens were found in 51.9%. The common first location was the respiratory tract (66.6%), followed by the abdominal site (19.7%). Candida colonisation was found in 64.6%, and invasive Candida infection in 34.0%. Identified fungi were Candida spp. in 98.6% and Aspergillus spp. in 6.1%. Patients with fungal pathogens showed a higher rate of postoperative peritonitis, APACHE II and tracheotomy. In comparison to patients without fungal pathogens, these patients showed a longer duration on mechanical ventilation, and a higher overall mortality. Patients with Candida-positive swabs from abdominal sites had more fascia dehiscence and anastomosis leakage. Seventy-two patients (48.9%) received antifungal therapy, 26 patients were treated empirically. Antifungal therapy was not associated with a decrease in mortality. Age and renal replacement therapy were associated with mortality. In conclusion, fungi are common pathogens in critically ill patients with peritonitis, and detection of fungi is associated with an increase in overall mortality. Particularly, Candida-positive abdominal swabs are associated with an increase in morbidity. However, we were not able to demonstrate a survival benefit for antifungal therapy in peritonitis patients. PMID:26010584

    Objective To validate the In-hospital Mortality for PulmonAry embolism using Claims daTa (IMPACT) prediction rule, in a database consisting only of inpatient claims. Design Retrospective claims database analysis. Setting The 2012 Healthcare Cost and Utilization Project National Inpatient Sample. Participants Pulmonary embolism (PE) admissions were identified by an International Classification of Diseases, ninth edition (ICD-9) code either in the primary position or secondary position when accompanied by a primary code for a PE complication. The multivariable IMPACT rule, which includes age and 11 comorbidities, was used to estimate patients’ probability of in-hospital mortality and classify them as low or higher risk (≤1.5% deemed low risk). Primary and secondary outcome measures The rule's sensitivity, specificity, positive and negative predictive values (PPV and NPV) and area under the receiver operating characteristic curve statistic for predicting in-hospital mortality with accompanying 95% CIs. Results A total of 34 108 admissions for PE were included, with a 3.4% in-hospital case-fatality rate. IMPACT classified 11 025 (32.3%) patients as low risk, and low risk patients had lower in-hospital mortality (OR, 0.17, 95% CI 0.13 to 0.21), shorter length of stay (−1.2 days, p<0.001) and lower total treatment costs (−$3074, p<0.001) than patients classified as higher risk. IMPACT had a sensitivity of 92.4%, 95% CI 90.7 to 93.8 and specificity of 33.2%, 95% CI 32.7 to 33.7 for classifying mortality risk. It had a high NPV (>99%), low PPV (4.6%) and an AUC of 0.74, 95% CI 0.73 to 0.76. Conclusions The IMPACT rule appeared valid when used in this all payer, inpatient only administrative claims database. Its high sensitivity and NPV suggest the probability of in-hospital death in those classified as low risk by IMPACT was minimal. PMID:26510731

    A century after its discovery, Chagas disease (CD) is still considered a public health problem. Mortality caused by CD between 2000 and 2010 was described according to the specific underlying cause, year of occurrence, gender, age range, and region of Brazil. The standardized mortality rate decreased 32.4%, from 3.4% in 2000 to 2.3% in 2010. Most of the deaths (85.9%) occurred in male patients who were > 60 years of age caused by cardiac involvement. The mortality rate caused by cardiac involvement decreased in all regions of Brazil, except in the North region, where it increased by 1.6%. The Northeast had the smallest and the Central-West had the largest decrease. The mortality rate caused by a compromised digestive tract increased in all regions. Despite the control of transmission by vector and blood transfusions, CD should remain on the list of priority diseases for the public health service in Brazil, and surveillance actions cannot be interrupted.

    Background Managing blood stream infection in Africa is hampered by lack of bacteriological support needed for antimicrobial stewardship, and background data needed for empirical treatment. A combined pro- and retrospective approach was used to overcome thresholds in clinical research in Africa. Methods Outcome and characteristics including age, HIV infection, pancytopenia and bacteriological results were studied in 292 adult patients with two or more SIRS criteria using univariate and confirming multivariate logistic regression models. Expected randomly distributed resistance covariation was compared with observed co-resistance among gram-negative enteric bacteria in 92 paediatric blood culture isolates that had been harvested in the same hospital during the same period of time. Results Mortality was fivefold increased among patients with positive blood culture results [50.0% vs. 9.8%; OR 11.24 (4.38–25.88), p < 0.0001], and for this group of patients mortality was significantly associated with antimicrobial resistance [OR 23.28 (3.3–164.4), p = 0.002]. All 11 patients with Enterobacteriaceae resistant to 3rd. generation cephalosporins died. Eighty-nine patients had pancytopenia grade 3–4. Among patients with negative blood culture results, mortality was significantly associated with pancytopenia [OR 3.12 (1.32–7.39), p = 0.01]. HIV positivity was not associated with increased mortality. Antimicrobial resistance that concerned gram-negative enteric bacteria, regardless of species, was characterized by co-resistance between third generation cephalosporins, gentamicin, chloramphenicol, and co-trimoxazole. Conclusion Mortality was strongly associated with growth of bacteria resistant to empirical treatment, and these patients were dead or dying when bacteriological reports arrived. Because of co-resistance, alternative efficient antibiotics would not have been available in Ethiopia for 8/11 Enterobacteriaceae-infected patients with isolates resistant to third

    Air pollution by fine particulate matter (PM2.5) and ozone (O3) has increased strongly with industrialization and urbanization. We estimate the premature mortality rates and the years of human life lost (YLL) caused by anthropogenic PM2.5 and O3 in 2005 for epidemiological regions defined by the World Health Organization (WHO). This is based upon high-resolution global model calculations that resolve urban and industrial regions in greater detail compared to previous work. Results indicate that 69% of the global population is exposed to an annual mean anthropogenic PM2.5 concentration of >10 μg m-3 (WHO guideline) and 33% to > 25 μg m-3 (EU directive). We applied an epidemiological health impact function and find that especially in large countries with extensive suburban and rural populations, air pollution-induced mortality rates have been underestimated given that previous studies largely focused on the urban environment. We calculate a global respiratory mortality of about 773 thousand/year (YLL ≈ 5.2 million/year), 186 thousand/year by lung cancer (YLL ≈ 1.7 million/year) and 2.0 million/year by cardiovascular disease (YLL ≈ 14.3 million/year). The global mean per capita mortality caused by air pollution is about 0.1% yr-1. The highest premature mortality rates are found in the Southeast Asia and Western Pacific regions (about 25% and 46% of the global rate, respectively) where more than a dozen of the most highly polluted megacities are located.

    Infectious hematopoietic necrosis virus caused mortality of sockeye salmon (Oncorhynchus nerka) in streamside egg incubation boxes. Virus was not detectable in eggs or alevins; its first isolation coincided with the appearance of dead fish in a trap on the outflow from the box. Mortality due to the virus did not occur in every egg box studied. However, when fry from the boxes were held in the laboratory, epizootics began as much as 3 wk later, with total mortality exceeding 90%. More than 96% of the dead fry had titers exceeding 105 plaque-forming units per gram. The peak incidence of virus in fry migrating in the river coincided with the arrival of hatchery-produced fry, although some fry believed to have been produced by natural spawning were also infected.Englis

    Background Traumatic brain injury related to road traffic accidents poses a major challenge in resource-poor settings within Guinea. Objective To analyze the impact of treatment delay, access to healthcare, and patient's financial capacity on duration of hospital stay and in-hospital mortality. Methodology Data from patients with traumatic brain injury secondary to motor vehicle accident admitted to a reference hospital (public or private) in Guinea during 2009 were analyzed. The association between various factors (treatment delay, access to healthcare, and patient's financial capacity) and prolonged hospital stay (>21 days) and in-hospital mortality were analyzed using two multivariate logistic regression models. Results The mean (±standard deviation) duration of hospital stay was 8.0 (±8.1) days. The risk of prolonged hospital stay increased by 60% when the time interval between accident and hospital arrival was greater than 12 hours compared with those in whom the time interval was less than 6 hours (adjusted odds ratio [OR] = 1.6, 95% confidence interval [CI] = 1.0–2.6, p = 0.03). Compared with patients with low-financial capacity, patients with medium-financial capacity (adjusted OR = 0.6, 95% CI = 0.4–0.8, p = 0.001) and those with high capacity (adjusted OR = 0.6, 95% CI = 0.4–0.9, p = 0.02) were less likely to have a prolonged hospital stay. The risk of in-hospital mortality was 2.6 times higher in patients with time interval between accident and hospital arrival greater than 12 hours compared with those in whom the time interval was less than 6 hours (adjusted OR = 2.6, 95% CI = 1.1–6.2 p = 0.03). In-hospital mortality was not related to patient’s financial capacity. Conclusion Prolonged hospital stay and higher in-hospital mortality was associated with longer time interval between accident and hospital arrival. This delay is attributed to inadequate condition of intercity roads and lack of emergency medical services. PMID:26576213

    The contribution of malaria to morbidity and mortality among people in Africa has been a subject of academic interest, political advocacy, and speculation. National statistics for much of sub-Saharan Africa have proved to be an unreliable source of disease-specific morbidity and mortality data. Credible estimates of disease-specific burdens are required for setting global and national priorities for health in order to rationalize the use of limited resources and lobby for financial support. We have taken an empirical approach to defining the limits of Plasmodium falciparum transmission across the continent and interpolated the distributions of projected populations in 1995. By combining a review of the literature on malaria in Africa and models of acquired functional immunity, we have estimated the age-structured rates of the fatal, morbid and disabling sequelae following exposure to malaria infection under different epidemiological conditions.

    OBJECTIVE: To compare mortality rates due to respiratory diseases among elderly individuals residing in the Federal District of Brasília, Brazil, prior to and after the implementation of a national influenza vaccination campaign. METHODS: This was an ecological time series analysis. Data regarding the population of individuals who were over 60 years of age between 1996 and 2009 were obtained from official databases. The variables of interest were the crude mortality rate (CMR), the mortality rate due to the respiratory disease (MRRD), and the proportional mortality ratio (PMR) for respiratory diseases. We performed a qualitative analysis of the data for the period prior to and after the implementation of the vaccination campaign (1996-1999 and 2000-2009, respectively). RESULTS: The CMR increased with advancing age. Over the course of the study period, we observed reductions in the CMR in all of the age brackets studied, particularly among those aged 80 years or older. Reductions in the MRRD were also found in all of the age groups, especially in those aged 80 years or older. In addition, there was a decrease in the PMR for respiratory diseases in all age groups throughout the study period. The most pronounced decrease in the PMR for respiratory diseases in the ≥ 70 year age bracket occurred in 2000 (immediately following the implementation of the national vaccination campaign); in 2001, that rate increased in all age groups, despite the greater adherence to the vaccination campaign in comparison with that recorded for 2000. CONCLUSIONS: Influenza vaccination appears to have a positive impact on the prevention of mortality due to respiratory diseases, particularly in the population aged 70 or over. PMID:23670505

    Background The cause of coronary disease inframortality in Spain is unknown. The aim of this study is to identify Spanish towns with very low ischemic heart disease mortality, describe their health and social characteristics, and analyze the relationship with a series of contextual factors. Methods We obtained the number of deaths registered for each of 8,122 Spanish towns in the periods 1989-1998 and 1999-2003. Expected deaths, standardized mortality ratio (SMR), smoothed Relative Risk (RR), and Posterior Probability (PP) of RR > 1 were calculated using Bayesian hierarchical models. Inframortality was defined as any town that displayed an RR below the 10th percentile, an SMR of under 1 for both sexes, and a PP of RR > 1 less than or equal to 0.002 for male and 0.005 for female mortality, during the two periods covered. All the remaining towns, except for those with high mortality classified as "tourist towns", were selected as controls. The association among socioeconomic, health, dietary, lifestyle and vascular risk factors was analyzed using sequential mixed logistic regression models, with province as the random-effects variable. Results We identified 32 towns in which ischemic heart disease mortality was half the national rate and four times lower than the European Union rate, situated in lightly populated provinces spread across the northern half of Spain, and revealed a surprising pattern of geographic aggegation for 23 of the 32 towns. Variables related with inframortality were: a less aged population (OR 0.93, 95% CI 0.89-0.99); a contextual dietary pattern marked by a high fish content (OR 2.13, 95% CI 1.38-3.28) and wine consumption (OR 1.50, 95% CI 1.08-2.07); and a low prevalence of obesity (OR 0.47, 95% CI 0.22-1.01); and, in the case of towns of over 1000 inhabitants, a higher physician-population ratio (OR 3.80, 95% CI 1.17-12.3). Conclusions Results indicate that dietary and health care factors have an influence on inframortality. The geographical

    Objectives To evaluate the short-term and long-term prognostic impacts of acute phase coronary collaterals to occluded infarct-related arteries (IRA) after ST-elevation myocardial infarction (STEMI) in the percutaneous coronary intervention (PCI) era. Design A prospective observational study. Setting Osaka Acute Coronary Insufficiency Study (OACIS) in Japan. Participants 3340 patients with STEMI from the OACIS database who were admitted to hospitals within 24 hours from the onset and who had a completely occluded IRA. Interventions Patients were divided into 4 groups according to the Rentrop collateral score (RCS) by angiography on admission (RCS-0, no visible collaterals; RCS-1, collaterals without IRA filling; RCS-2, collaterals with partial IRA filling; and RCS-3, collaterals with complete IRA filling). Primary outcome measures In-hospital and 5-year mortality. Results Patients with RCS-0/3 were older than patients with RCS-1/2, and the prevalence of previous myocardial infarction was highest in patients with RCS-3. Median peak creatinine phosphokinase levels decreased as RCS increases (p<0.001), suggesting the acute cardioprotective effects of collaterals. Although RCS-1 and RCS-2 collaterals were associated with better in-hospital mortality (adjusted OR 0.48, p=0.046 and 0.38, p=0.010 for RCS-1 and RCS-2, respectively) and 5-year mortality (adjusted HR 0.53, p=0.004 and 0.46, p<0.001 for RCS-1 and RCS-2, respectively) as compared with R-0, presence of RCS-3 collaterals was not associated with improved in-hospital (adjusted OR 1.35, p=0.331) and 5-year mortality (adjusted HR 0.98, p=0.920), possibly because worse clinical profiles in patients with RCS-3 may mask mortality benefit of coronary collaterals. Conclusions Presence of acute phase coronary collaterals such as RCS-1 and RCS-2 were associated with better in-hospital and 5-year mortality after STEMI in the contemporary PCI era. PMID:27412101

    Abstract The factors involved in the long-term perpetuation of Francisella tularensis tularensis in nature are poorly understood. Martha's Vineyard, Massachusetts, has become a site of sustained transmission of Type A tularemia, with nearly 100 human cases reported from 2000 to 2010. We have identified a stable focus of F. tularensis transmission there, where the annual prevalence in host-seeking Dermacentor variabilis is about 3%, suggesting that this tick perpetuates the agent. However, laboratory studies have shown that infection with F. tularensis has a profound negative effect on dog tick mortality, presenting a paradox: how can a vector perpetuate an agent that negatively affects its fitness? It may be that experimental infection does not mimic that of natural transmission. Accordingly, we examined the effects that F. tularensis has on the longevity of field-derived ticks. Of 63 PCR-positive ticks collected in early summer, 89% were dead by December compared to 48% of 214 uninfected ticks collected at the same time and site. However, the quantum of F. tularensis DNA within each tick was not correlated with increased mortality. Instead, ticks with an uncommon genotype were more likely to die early than those with the common genotype. We conclude that the interaction between F. tularensis and its vector is complex and certain bacterial genotypes appear to be better adapted to their arthropod host. PMID:21612530

    During a routine telemetry flight of the Mojave Desert (California, USA) in August 1995, mortality signals were detected from two of 12 radio-collared female desert bighorn sheep (Ovis canadensis) in the vicinity of Old Dad Peak in San Bernardino County (California). A series of field investigations determined that at least 45 bighorn sheep had died near two artificial water catchments (guzzlers), including 13 bighorn sheep which had presumably drowned in a guzzler tank. Samples from water contaminated by decomposing bighorn sheep carcasses and hemolyzed blood from a fresh bighorn sheep carcass were tested for the presence of pesticides, heavy metals, strychnine, blue-green algae, Clostridium botulinum toxin, ethylene glycol, nitrates, nitrites, sodium, and salts. Mouse bioassay and enzyme-linked immunosorbent assay detected type C botulinum toxin in the hemolyzed blood and in fly larvae and pupae. This, coupled with negative results from other analyses, led us to conclude that type C botulinum poisoning was most likely responsible for the mortality of bighorn sheep outside the guzzler tank.

    Climate change may drive a late-century replacement of Amazon forests by fire-prone scrub vegetation. These model-based predictions do not consider the positive feedbacks between fire disturbance and extreme weather events, which could accelerate forest replacement. Here we present the first field-based evidence of a near-term tipping point in Amazon forest fire regimes. We found a two to four-fould increase in fire-induced tree mortality during an extreme drought. This threshold mortality response had a cascading effect, causing sharp declines in canopy cover and aboveground live biomass relative to an unburned control, while favoring widespread invasion by flammable grasses across 32-37% of the forest edge. Regional forest fires burned up to 12% of southeast Amazon forests during recent droughts, but less than 1% in non-drought years. The process of severe climate-induced forest degradation predicted by models for the later part of this century could be triggered sooner by widespread and high-intensity fires.

    A total of 26,203 of the deaths in Jerez de los Caballeros (Badajoz) during the 19th century were collected and grouped according to the Bertillon's Classification, in order to study the causes of death from rheumatic diseases. An analysis was made using the Death Registers, those located in the Parish Archives, and files of the Municipal Archives. There were a total of 31 deaths due to rheumatic diseases, with the 65-74 years age group being most frequent. The lack of records may be due to the inaccuracy of the diagnoses. September was the month of increased mortality. PMID:26139377

    The purpose of this analysis was to quantify and adjust for disease misclassification from loss to follow-up in a historical cohort mortality study of workers where exposure was categorized as a multi-level variable. Disease classification parameters were defined using 2008 mortality data for the New Zealand population and the proportions of known deaths observed for the cohort. The probability distributions for each classification parameter were constructed to account for potential differences in mortality due to exposure status, gender, and ethnicity. Probabilistic uncertainty analysis (bias analysis), which uses Monte Carlo techniques, was then used to sample each parameter distribution 50,000 times, calculating adjusted odds ratios (ORDM-LTF) that compared the mortality of workers with the highest cumulative exposure to those that were considered never-exposed. The geometric mean ORDM-LTF ranged between 1.65 (certainty interval (CI): 0.50–3.88) and 3.33 (CI: 1.21–10.48), and the geometric mean of the disease-misclassification error factor (εDM-LTF), which is the ratio of the observed odds ratio to the adjusted odds ratio, had a range of 0.91 (CI: 0.29–2.52) to 1.85 (CI: 0.78–6.07). Only when workers in the highest exposure category were more likely than those never-exposed to be misclassified as non-cases did the ORDM-LTF frequency distributions shift further away from the null. The application of uncertainty analysis to historical cohort mortality studies with multi-level exposures can provide valuable insight into the magnitude and direction of study error resulting from losses to follow-up.

    Introduction Natural history of chronic obstructive pulmonary disease (COPD) is punctuated by exacerbations; however, little is known about prognosis of the first-ever COPD exacerbation and variables predicting its outcomes. Materials and Methods A population-based cohort study among COPD patients with their first-ever exacerbations requiring hospitalizations was conducted. Main outcomes were in-hospital mortality and one-year mortality after discharge. Demographics, comorbidities, medications and in-hospital events were obtained to explore outcome predictors. Results The cohort comprised 4204 hospitalized COPD patients, of whom 175 (4%) died during the hospitalization. In-hospital mortality was related to higher age (odds ratio [OR]: 1.05 per year; 95% confidence interval [CI]: 1.03–1.06) and Charlson comorbidity index score (OR: 1.08 per point; 95% CI: 1.01–1.15); angiotensin II receptor blockers (OR: 0.61; 95% CI: 0.38–0.98) and β blockers (OR: 0.63; 95% CI: 0.41–0.95) conferred a survival benefit. At one year after discharge, 22% (871/4029) of hospital survivors were dead. On multivariate Cox regression analysis, age and Charlson comorbidity index remained independent predictors of one-year mortality. Longer hospital stay (hazard ratio [HR] 1.01 per day; 95% CI: 1.01–1.01) and ICU admission (HR: 1.33; 95% CI: 1.03–1.73) during the hospitalization were associated with higher mortality risks. Prescription of β blockers (HR: 0.79; 95% CI: 0.67–0.93) and statins (HR: 0.66; 95% CI: 0.47–0.91) on hospital discharge were protective against one-year mortality. Conclusions Even the first-ever severe COPD exacerbation signifies poor prognosis in COPD patients. Comorbidities play a crucial role in determining outcomes and should be carefully assessed. Angiotensin II receptor blockers, β blockers and statins may, in theory, have dual cardiopulmonary protective properties and probably alter prognosis of COPD patients. Nevertheless, the limitations

    Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall. PMID:17898820

    Alcohol consumption is causally related to cancer of the upper aero-digestive tract, liver, colon, rectum, female breast and pancreas. The dose response relationship varies for each site. We calculated Ireland's cancer incidence and mortality attributable to alcohol over a 10-year period. Between 2001 and 2010, 4,585 (4.7%) male and 4,593 (4.2%) female invasive cancer diagnoses were attributable to alcohol. The greatest risk was for the upper aero-digestive tract where 2,961 (52.9%) of these cancers in males and 866 (35.2%) in females were attributable to alcohol. Between 2001 and 2010, 2,823 (6.7%) of male cancer deaths and 1,700 (4.6%) of female cancer deaths were attributable to alcohol. Every year approximately 900 new cancers and 500 cancer deaths are attributable to alcohol. Alcohol is a major cause of cancer after smoking, obesity and physical inactivity. Public awareness of risk must improve. Over half of alcohol related cancers are preventable by adhering to Department of Health alcohol consumption guidelines. PMID:24579406

    The aim of this research is to study all people who died in the Autonomous Community of Galicia from acute death after drugconsumption (ADR) in which there was judicial intervention during the period from 1997 to 2011, according to inclusion and exclusión criteria established by the National Drug Plan for the entire national territory. Sociodemographic and clinical characteristics of deceased subjects were studied, in order to identify key risk factors and/or vulnerable populations.A total of 805 deaths were recorded. The distribution by provinces and municipalities corresponds to the areas of greatest population, incidence of consumption and proximity to the coast. The average age of these patients was 34.34 years, with a gradual increase over years. Most of them were male (91.2%) and single (47.7). 43.5% of the deceased habitually used the parenteral route of administration and 36.4% had positive HIV serology. The most frequently-detected substances corresponded to opiates (heroin: 61.3%, methadone: 35.6%), followed by cocaine (53.7%), although the most common pattern was that of poly-consumption. ADR mortality figures remain relatively stable throughout the study period. The predominant pattern is that of males, opiates and a long history of consumption. PMID:26990265

    Background Cutaneous melanoma is a skin cancer with low incidence but high mortality rates. The South region of Brazil has the highest death rates by melanoma per 100,000 inhabitants of the country. Little is known about the spatial distribution of this malignancy in southern Brazil. Objectives Identify the spatial patterns of deaths from cutaneous melanoma in South region of Brazil, using geoprocessing tools. Methods This is an ecological and exploratory study of death information by cutaneous melanoma obtained from portal Datasus, for Brazil's southern region, from January 2008 to December 2012. Deaths were separated by gender and rates per 100,000 inhabitants were calculated and used to compile thematic maps, Moran maps and Kernel maps, using TerraView software. It was adopted an alpha = 5%. Results There were data on 2378 deaths from cutaneous melanoma in the study period. High rates were identified in the northern and littoral regions of Rio Grande do Sul; the northeast of Santa Catarina; and west of Paraná - for the total population, with minor differences detected and indicated regarding gender. The global Moran index presented p-values of 0.03, 0.04 and 0.03, respectively, for male, female and overall deaths. All the micro-regions that showed high priority for intervention were detected in the Rio Grande do Sul. Conclusion Spatial clusters of micro-regions with high death rates from cutaneous melanoma in South region of Brazil were identified, serving as an important tool for health managers. PMID:27579737

    Almost all (99%) neonatal deaths occur in developing countries, where the progress in reducing neonatal mortality rates (NMR) has been small; the Millennium Development Goal for child survival cannot be met if this situation continues. China is among the 10 countries that have the largest numbers of neonatal deaths. In order to provide effective interventions to reduce the national NMR for government policy makers, we analyse the trends, causes and characteristics of the neonatal deaths of preterm babies in different regions of China during the period 2003-2008. The data for this retrospective study were retrieved from the population-based Maternal and Child Health Surveillance System of China. The Cochran-Armitage trend test was used to analyse the trend of NMRs due to immaturity. The national NMR due to immaturity has decreased by 38.7% in 6 years. However, the proportion of preterm births among the causes of neonatal death has increased significantly from 33.6% in 2003 to 40.9% in 2008. The relative risk of neonatal death among preterm babies has shown significant regional disparity. In 2008, the adjusted relative risk was 1.30 [95% confidence interval (CI) 0.95, 1.78] in the inland regions and 2.37 [95% CI 1.56, 3.60] in the remote regions, both compared with the coastal regions. The proportion of neonatal deaths with a gestational age <32 weeks or a birthweight <1500 g was highest among the coastal regions. Most neonatal deaths of preterm babies in remote areas were born at home and were not treated before death. Our study suggests that preterm birth is the leading cause of neonatal death in China and neonatal mortality due to immaturity displayed regional differences. The Chinese government should implement major effective strategies for reducing the mortality of preterm infants to further decrease the total NMR. Priority interventions should be region-specific, depending on the availability of economic and health care resources. PMID:21980948

    Objectives A growing number of epidemiological studies are showing that ambient exposure to particulate matter air pollution is a risk factor for cardiovascular disease; however, whether occupational exposure increases this risk is not clear. The aim of the present study was to examine whether occupational exposure to particulate air pollution increases the risk for ischaemic heart disease and cerebrovascular disease. Methods The study population was a cohort of 176 309 occupationally exposed Swedish male construction workers and 71 778 unexposed male construction workers. The definition of exposure to inorganic dust (asbestos, man‐made mineral fibres, dust from cement, concrete and quartz), wood dust, fumes (metal fumes, asphalt fumes and diesel exhaust) and gases and irritants (organic solvents and reactive chemicals) was based on a job‐exposure matrix with focus on exposure in the mid‐1970s. The cohort was followed from 1971 to 2002 with regard to mortality to ischaemic heart disease and cerebrovascular disease. Relative risks (RR) were obtained by the person‐years method and from Poisson regression models adjusting for baseline values of blood pressure, body mass index, age and smoking habits. Results Any occupational particulate air pollution was associated with an increased risk for ischemic heart disease (RR 1.13, 95% CI 1.07 to 1.19), but there was no increased risk for cerebrovascular disease (RR 0.97, 95% CI 0.88 to 1.07). There was an increased risk for ischaemic heart disease and exposure to inorganic dust (RR 1.07, 95% CI 1.03 to 1.12) and exposure to fumes (RR 1.05, 95% CI 1.00 to 1.10), especially diesel exhaust (RR 1.18, 95% CI 1.13 to 1.24). There was no significantly increased risk for cerebrovascular disease and exposure to inorganic dust, fumes or wood dust. Conclusions Occupational exposure to particulate air pollution, especially diesel exhaust, among construction workers increases the risk for ischaemic heart disease. PMID

    Background: Schizophrenia is among the major causes of disability worldwide and the mortality from cardiovascular disease (CVD) is significantly elevated. There is a growing concern that this health challenge is not fully understood and efficiently addressed. Methods: Non-systematic review using searches in PubMed on relevant topics as well as selection of references based on the authors’ experience from clinical work and research in the field. Results: In most countries, the standardized mortality rate in schizophrenia is about 2.5, leading to a reduction in life expectancy between 15 and 20 years. A major contributor of the increased mortality is due to CVD, with CVD mortality ranging from 40 to 50% in most studies. Important causal factors are related to lifestyle, including poor diet, lack of physical activity, smoking, and substance abuse. Recent findings suggest that there are overlapping pathophysiology and genetics between schizophrenia and CVD-risk factors, further increasing the liability to CVD in schizophrenia. Many pharmacological agents used for treating psychotic disorders have side effects augmenting CVD risk. Although several CVD-risk factors can be effectively prevented and treated, the provision of somatic health services to people with schizophrenia seems inadequate. Further, there is a sparseness of studies investigating the effects of lifestyle interventions in schizophrenia, and there is little knowledge about effective programs targeting physical health in this population. Discussion: The risk for CVD and CVD-related deaths in people with schizophrenia is increased, but the underlying mechanisms are not fully known. Coordinated interventions in different health care settings could probably reduce the risk. There is an urgent need to develop and implement effective programs to increase life expectancy in schizophrenia, and we argue that mental health workers should be more involved in this important task.

    Introduction The analysis of premature deaths measured with years of life lost between the studied and referential populations helps to emphasize the social and economic aspect of a loss caused by deaths due to malignant neoplasms. The aim of the study was to analyze years of life lost by inhabitants of the Lodz province due to malignant neoplasms. Material and methods The study material included a database which contained information gathered from 313,144 death certificates (including 66,899 people who died of malignant neoplasms) of inhabitants of the Lodz province who died between 1999 and 2008. The SEYLLp (Standard Expected Years of Life Lost per living person) method was used to determine years of life lost. Jointpoint models were used to analyze time trends. Results In males the diseases which mostly contributed to death were tracheal, bronchial and lung malignant neoplasms (SEYLLp = 170.7) and cancer of the large intestine, rectum and anus (SEYLLp = 47.5). In females the principal diseases were tracheal, bronchial and lung malignant neoplasms (SEYLLp = 61.6), breast cancer (SEYLLp = 60.4) and cancer of the large intestine, rectum and anus (SEYLLp = 42.3). The years of life lost were growing in the period under study. Conclusions The number of years lost due to malignant neoplasms in the Lodz province between 1999 and 2008 was growing. The main reasons for deaths in females were tracheal, bronchial and lung malignant neoplasms as well as breast cancer and in males – cancer of the large intestine, rectum and anus as well as prostate cancer.

    BACKGROUND: Previous risk scores have shown excellent performance. However, the need for real-time risk score computation makes their implementation in an emergent situation challenging. A more simplified approach can provide practitioners with a practical bedside risk stratification tool. METHODS: We developed an easy-to-use tree-structured risk stratification model for patients undergoing early Percutaneous Coronary Intervention (PCI) for Acute Myocardial Infraction (AMI). The model was developed on the New York State PCI database for 1999-2000 (consisting of 5385 procedures) and was validated using the subsequent 2001-2002 database (consisting of 7414 procedures). RESULTS: Tree-structured modeling identified three key presenting features: cardiogenic shock, congestive heart failure and age. In the validation dataset, this risk stratification model identified patient groups with in-hospital mortality ranging from 0.5% to 20.6%, more than a twenty-fold increased risk. The performance of this model was similar to the Mayo Clinic Risk Score with a discriminative capacity of 82% (95% CI: 79%, 84%) versus 80% (95% CI: 77%, 82%), respectively. CONCLUSION: Patients undergoing PCI for AMI can be readily stratified into risk categories using the tree-structured model. This provides practicing cardiologists with an internally validated and easy-to-use scheme for in-hospital mortality risk stratification. PMID:17643583

    A follow-up study of 162 men already working as insulators (laggers) in 1940 has been extended from 1965 to 1975. By the end of 1975 there were 40 survivors when 108 had been expected. Until 1965 there had been an overall excess of deaths; these were due to asbestosis with or without tuberculosis and to alimentary cancer, as well as to bronchial carcinoma and mesothelioma. From 1965 onwards the overall death rate among survivors is not so excessive but there is still a marked excess of deaths from bronchial cancer and mesothelioma. The continued risk of death attributable to malignancy after asbestosis had ceased to contribute directly, does not appear to be caused by any changes which occurred before 1940 in the conditions at work.

    A female longfin mako shark Isurus paucus (Guitart-Manday, 1966) was found moribund on the Atlantic Ocean beach near Canaveral National Seashore, Florida; the shark died shortly after stranding. Macroscopic lesions included a partially healed bite mark on the left pectoral fin, a clefted snout, pericardial effusion and a pericardial mass surrounding a 12/0 circle fishing hook. The heart, pericardial mass, gills, ovary, oviduct, shell gland, epigonal organ, liver, kidney and intrarenal and interrenal glands were processed for histopathology and examined by brightfield microscopy. Microscopic examination revealed chronic proliferative and pyogranulomatous pericarditis and myocarditis with rhabdomyolysis, fibrosis and thrombosis; scant bacteria and multifocal granular deposits of iron were found intralesionally. In addition, acute, multifocal infarcts within the epigonal organ and gill filaments were found in association with emboli formed by necrocellular material. The ovary had high numbers of atretic follicles, and the liver had diffuse, severe hepatocellular degeneration, multifocal spongiosis and moderate numbers of melanomacrophage cells. This report provides evidence of direct mortality due to systemic lesions associated with retained fishing gear in a prohibited shark species. Due to the large numbers of sharks released from both recreational and commercial fisheries worldwide, impact of delayed post-release mortality on shark populations is an important consideration.

    Our objective was to construct and validate a Multidimensional Prognostic Index (MPI) for 1-year mortality from a Comprehensive Geriatric Assessment (CGA) routinely carried out in elderly patients in a geriatric acute ward. The CGA included clinical, cognitive, functional, nutritional, and social parameters and was carried out using six standardized scales and information on medications and social support network, for a total of 63 items in eight domains. A MPI was developed from CGA data by aggregating the total scores of the eight domains and expressing it as a score from 0 to 1. Three grades of MPI were identified: low risk, 0.0-0.33; moderate risk, 0.34-0.66; and severe risk, 0.67-1.0. Using the proportional hazard models, we studied the predictive value of the MPI for all causes of mortality over a 12-month follow-up period. MPI was then validated in a different cohort of consecutively hospitalized patients. The development cohort included 838 and the validation cohort 857 elderly hospitalized patients. Of the patients in the two cohorts, 53.3 and 54.9% were classified in the low-risk group, respectively (MPI mean value, 0.18 +/- 0.09 and 0.18 +/- 0.09); 31.2 and 30.6% in the moderate-risk group (0.48 +/- 0.09 and 0.49 +/- 0.09); 15.4 and 14.2% in the severe-risk group (0.77 +/- 0.08 and 0.75 +/- 0.07). In both cohorts, higher MPI scores were significantly associated with older age (p = 0.0001), female sex (p = 0.0001), lower educational level (p = 0.0001), and higher mortality (p = 0.0001). In both cohorts, a close agreement was found between the estimated mortality and the observed mortality after both 6 months and 1 year of follow-up. The discrimination of the MPI was also good, with a ROC area of 0.751 (95%CI, 0.70-0.80) at 6 months and 0.751 (95%CI, 0.71-0.80) at 1 year of follow-up. We conclude that this MPI, calculated from information collected in a standardized CGA, accurately stratifies hospitalized elderly patients into groups at varying risk of

    Background Pulmonary tuberculosis with acute respiratory failure is fatal and is a burden in the intensive care units and leads to mortality. This retrospective study identifies the factors influencing the development of pulmonary tuberculosis requiring mechanical ventilation (TBMV) and mortality in the hospitalized patients with pulmonary tuberculosis. Methods The medical records of hospitalized adult patients with pulmonary tuberculosis were retrospectively reviewed. Demographic data, clinical presentations, radiographic findings, biochemical tests, and clinical outcomes were collected. Data were compared by Student’s t-test and Chi-square test between groups. Select variables that were statistically significant with P values <0.1 were introduced into a forward, stepwise, logistic regression model. Odds ratios (ORs) and their 95% confidence intervals (CIs) identified the independent influencing factors in the development of TBMV and mortality. Results Of 268 enrolled patients, 185 (69.0%) were male. The patients were equally divided between the TBMV and non-TBMV groups. The shorter duration of illness (OR, 0.99; 95% CI, 0.98–0.99), underlying disease of AIDS (OR, 14.55; 95% CI, 1.71–123.91), presentation of fever (OR, 2.11; 95% CI, 1.20–3.71) and dyspnea (OR, 3.51; 95% CI, 2.02–6.11), large amount of acid fast bacilli on sputum smear (OR, 3.76; 95% CI, 1.90–7.47), lower serum albumin level (OR, 0.39; 95% CI, 0.26–0.59), and delayed initiation of anti-tuberculosis agents (OR, 1.06; 95% CI, 1.00–1.12) were independent factors to develop TBMV. Male gender (OR, 2.16; 95% CI, 1.01–4.61), consolidation pattern on chest X-ray (OR, 2.41; 95% CI, 1.17–4.98), and lower serum albumin (OR, 0.39; 95% CI, 0.21–0.71) were correlated to mortality. Conclusions The incidence and mortality rate of TBMV patients were high.

    The negative impacts of fine particulate matter (PM2.5) exposure on human health are a primary motivator for air quality research. However, estimates of the air pollution health burden vary considerably and strongly depend on the datasets and methodology. Satellite observations of aerosol optical depth (AOD) have been widely used to overcome limited coverage from surface monitoring and to assess the global population exposure to PM2.5 and the associated premature mortality. Here we quantify the uncertainty in determining the burden of disease using this approach, discuss different methods and datasets, and explain sources of discrepancies among values in the literature. For this purpose we primarily use the MODIS satellite observations in concert with the GEOS-Chem chemical transport model. We contrast results in the United States and China for the years 2004-2011. We estimate that in the United States, exposure to PM2.5 accounts for approximately 4 % of total deaths compared to 22 % in China (using satellite-based exposure), which falls within the range of previous estimates. The difference in estimated mortality burden based solely on a global model vs. that derived from satellite is approximately 9 % for the US and 4 % for China on a nationwide basis, although regionally the differences can be much greater. This difference is overshadowed by the uncertainty in the methodology for deriving PM2.5 burden from satellite observations, which we quantify to be on order of 20 % due to uncertainties in the AOD-to-surface-PM2.5 relationship, 10 % due to the satellite observational uncertainty, and 30 % or greater uncertainty associated with the application of concentration response functions to estimated exposure.

    The negative impacts of fine particulate matter (PM2.5) exposure on human health are a primary motivator for air quality research. However, estimates of the air pollution health burden vary considerably and strongly depend on the data sets and methodology. Satellite observations of aerosol optical depth (AOD) have been widely used to overcome limited coverage from surface monitoring and to assess the global population exposure to PM2.5 and the associated premature mortality. Here we quantify the uncertainty in determining the burden of disease using this approach, discuss different methods and data sets, and explain sources of discrepancies among values in the literature. For this purpose we primarily use the MODIS satellite observations in concert with the GEOS-Chem chemical transport model. We contrast results in the United States and China for the years 2004-2011. Using the Burnett et al. (2014) integrated exposure response function, we estimate that in the United States, exposure to PM2.5 accounts for approximately 2 % of total deaths compared to 14 % in China (using satellite-based exposure), which falls within the range of previous estimates. The difference in estimated mortality burden based solely on a global model vs. that derived from satellite is approximately 14 % for the US and 2 % for China on a nationwide basis, although regionally the differences can be much greater. This difference is overshadowed by the uncertainty in the methodology for deriving PM2.5 burden from satellite observations, which we quantify to be on the order of 20 % due to uncertainties in the AOD-to-surface-PM2.5 relationship, 10 % due to the satellite observational uncertainty, and 30 % or greater uncertainty associated with the application of concentration response functions to estimated exposure.

    In this study, the Vaccine Adverse Event Reporting System (VAERS) database, 1990–2010, was investigated; cases that specified either hospitalization or death were identified among 38,801 reports of infants. Based on the types of vaccines reported, the actual number of vaccine doses administered, from 1 to 8, was summed for each case. Linear regression analysis of hospitalization rates as a function of (a) the number of reported vaccine doses and (b) patient age yielded a linear relationship with r 2 = 0.91 and r 2 = 0.95, respectively. The hospitalization rate increased linearly from 11.0% (107 of 969) for 2 doses to 23.5% (661 of 2817) for 8 doses and decreased linearly from 20.1% (154 of 765) for children aged <0.1 year to 10.7% (86 of 801) for children aged 0.9 year. The rate ratio (RR) of the mortality rate for 5–8 vaccine doses to 1–4 vaccine doses is 1.5 (95% confidence interval (CI), 1.4–1.7), indicating a statistically significant increase from 3.6% (95% CI, 3.2–3.9%) deaths associated with 1–4 vaccine doses to 5.5% (95% CI, 5.2–5.7%) associated with 5–8 vaccine doses. The male-to-female mortality RR was 1.4 (95% CI, 1.3–1.5). Our findings show a positive correlation between the number of vaccine doses administered and the percentage of hospitalizations and deaths. Since vaccines are given to millions of infants annually, it is imperative that health authorities have scientific data from synergistic toxicity studies on all combinations of vaccines that infants might receive. Finding ways to increase vaccine safety should be the highest priority. PMID:22531966

    Cerebrovascular diseases, including intracerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage, remain prevalent causes of morbidity and mortality among dialysis patients. Their mortality rate for cerebrovascular diseases is roughly three times higher than that in the general population. However, whether mortality rates for all subtypes of cerebrovascular diseases are equally higher has not been evaluated. The aim of this study was to determine the mortality rate for each stroke subtype, comparing dialysis patients and the general population in Japan. We used mortality data reported by the Japanese Society for Dialysis Therapy and national Vital Statistics data between 2008 and 2009. We calculated standardized mortality ratios and compared the mortality rates for stroke subtypes including intracerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage. During the 2-year study period, 51 994 and 933 deaths from intracerebral hemorrhage, 79 124 and 511 deaths from cerebral infarction, and 24 957 and 147 deaths from subarachnoid hemorrhage were recorded per 252 million person-years and per 546 474 dialysis patient-years, respectively. Standardized mortality ratios among dialysis patients relative to the general population were 3.8 (95% confidence interval, 3.6-4.1), 1.3 (1.2-1.4), and 1.3 (1.1-1.6) for intracerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage, respectively. Intracerebral hemorrhage was the highest cause of mortality in the dialysis population, although cerebral infarction was the highest in the general population. Relative to the general population in Japan, Japanese dialysis patients had higher mortality rates, especially for intracerebral hemorrhage. PMID:25196294

    5-10% of in-hospital patients are affected by adverse events, 10% of these requiring CPR. Standardized in-hospital emergency management may improve results, including reduction of mortality, hospital stay and cost. Early warning scores and clinical care outreach teams may help to identify patients at risk and should be combined with standard operation procedure and consented alarm criteria. These teams of doctors and nurses should be called for all in hospital emergencies, providing high-end care and initiate ICU measures at bedside. In combination with standard means of documentation assessment and evaluation--including entry in specific registers--the quality of in-hospital emergency management and patient safety could be improved.

    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

    Ischaemic heart disease (IHD) is one of the leading causes of death worldwide. The effects of air pollution on IHD mortalities have been widely reported. Fewer studies focus on IHD morbidities and PM2.5, especially in Asia. To explore the associations between short-term exposure to air pollution and morbidities and mortalities from IHD, we conducted a time series study using a generalized additive model that regressed the daily numbers of IHD mortalities and hospital admissions on daily mean concentrations of the following air pollutants: nitrogen dioxide (NO2), particulate matter with an aerodynamic diameter less than 10 μm (PM10), particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5), ozone (O3), and sulfur dioxide (SO2). The relative risks (RR) of IHD deaths and hospital admissions per 10 μg/m3 increase in the concentration of each air pollutant were derived in single pollutant models. Multipollutant models were also constructed to estimate their RRs controlling for other pollutants. Significant RRs were observed for all five air pollutants, ranging from 1.008 to 1.032 per 10 μg/m3 increase in air pollutant concentrations for IHD mortality and from 1.006 to 1.021 per 10 μg/m3 for hospital admissions for IHD. In the multipollutant model, only NO2 remained significant for IHD mortality while SO2 and PM2.5 was significantly associated with hospital admissions. This study provides additional evidence that mortalities and hospital admissions for IHD are significantly associated with air pollution. However, we cannot attribute these health effects to a specific air pollutant, owing to high collinearity between some air pollutants.

    Background The relationship between ambient air pollution exposure and mortality of cardiovascular and cerebrovascular diseases in human is controversial, and there is little information about how exposures to ambient air pollution contribution to the mortality of cardiovascular and cerebrovascular diseases among Chinese. The aim of the present study was to examine whether exposure to ambient-air pollution increases the risk for cardiovascular and cerebrovascular disease. Methodology/Principal Findings We conducted a retrospective cohort study among humans to examine the association between compound-air pollutants [particulate matter <10 µm in aerodynamic diameter (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NO2)] and mortality in Shenyang, China, using 12 years of data (1998–2009). Also, stratified analysis by sex, age, education, and income was conducted for cardiovascular and cerebrovascular mortality. The results showed that an increase of 10 µg/m3 in a year average concentration of PM10 corresponds to 55% increase in the risk of a death cardiovascular disease (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.51 to 1.60) and 49% increase in cerebrovascular disease (HR, 1.49; 95% CI, 1.45 to 1.53), respectively. The corresponding figures of adjusted HR (95%CI) for a 10 µg/m3 increase in NO2 was 2.46 (2.31 to 2.63) for cardiovascular mortality and 2.44 (2.27 to 2.62) for cerebrovascular mortality, respectively. The effects of air pollution were more evident in female that in male, and nonsmokers and residents with BMI<18.5 were more vulnerable to outdoor air pollution. Conclusion/Significance Long-term exposure to ambient air pollution is associated with the death of cardiovascular and cerebrovascular diseases among Chinese populations. PMID:21695220

    The aim of the study is to classify the synoptic sequences associated with excess mortality during the warm season in the Barcelona metropolitan area. To achieve this purpose, we undertook a principal sequence pattern analysis that incorporates different atmospheric levels, in an attempt at identifying the main features that account for dynamic and thermodynamic atmospheric processes. The sequence length was determined by the short-term displacement between temperature and mortality. To detect this lag, we applied the cross-correlation function to the residuals obtained from the modelling of the daily temperature and mortality series of summer. These residuals were estimated by means of an autoregressive integrated moving average (ARIMA) model. A 7-day sequence emerged as the basic temporal unit for evaluating the synoptic background that triggers the temperature related to excess mortality in the Barcelona metropolitan area. The principal sequence pattern analysis distinguished three main synoptic patterns: two dynamic configurations produced by southern fluxes related to an Atlantic low, which can be associated with heat waves recorded in southern Europe, and a third pattern identified by a stagnation situation associated with the persistence of a blocking anticyclone over Europe, related to heat waves recorded in northern and central western Europe.

    The purpose of this study was to compare the predicted risks of second malignant neoplasm (SMN) incidence and mortality from secondary neutrons for a 9-year-old girl and a 10-year-old boy who received proton craniospinal irradiation (CSI). SMN incidence and mortality from neutrons were predicted from equivalent doses to radiosensitive organs for cranial, spinal and intracranial boost fields. Therapeutic proton absorbed dose and equivalent dose from neutrons were calculated using Monte Carlo simulations. Risks of SMN incidence and mortality in most organs and tissues were predicted by applying risks models from the National Research Council of the National Academies to the equivalent dose from neutrons; for non-melanoma skin cancer, risk models from the International Commission on Radiological Protection were applied. The lifetime absolute risks of SMN incidence due to neutrons were 14.8% and 8.5%, for the girl and boy, respectively. The risks of a fatal SMN were 5.3% and 3.4% for the girl and boy, respectively. The girl had a greater risk for any SMN except colon and liver cancers, indicating that the girl's higher risks were not attributable solely to greater susceptibility to breast cancer. Lung cancer predominated the risk of SMN mortality for both patients. This study suggests that the risks of SMN incidence and mortality from neutrons may be greater for girls than for boys treated with proton CSI.

    Cerebral collateral circulation provides alternative vascular routes for blood to reach ischemic tissues during stroke. Collateral therapeutics attempt to augment flow through these collateral channels to reduce ischemia and brain damage during acute ischemic stroke. Transient aortic occlusion (TAO) has pre-clinical data suggesting that it can augment collateral blood flow and clinical data suggesting a benefit for patients with moderate cortical strokes. By diverting blood from the periphery towards the cerebral circulation, TAO has the potential to augment primary collateral flow at the circle of Willis and thereby improve outcome even during large, hemispheric strokes. Using proximal middle and anterior cerebral artery occlusion in rats, we demonstrate that TAO reduces mortality and improves collateral blood flow in severely ischemic animals. As such, TAO may be an effective therapy to reduce early mortality during severe ischemia associated with proximal occlusions. PMID:26706246

    Although the protease inhibitors have revolutionized the therapy of chronic hepatitis C (CHC), the concomitant use of pegylated-interferon (PEG-IFN) and ribavirin (RBV) is associated to a high rate of adverse effects. In this study, we evaluated the consequences of PEG-IFN and RBV and their relationship with mortality in patients with cirrhosis. METHODS: Medical records of CHC who underwent treatment with PEG-IFN and RBV in a public hospital in Brazil were evaluated. All the patients with cirrhosis were selected, and their clinical and laboratory characteristics, response to treatment, side effects and mortality were evaluated. RESULTS: From the 1,059 patients with CHC, 257 cirrhotic patients were evaluated. Of these, 45 (17.5%) achieved sustained viral response (SVR). Early discontinuation of therapy occurred in 105 (40.8%) patients, of which 39 (15.2%) were due to serious adverse effects. The mortality rate among the 257 cirrhotic patients was 4.3%, occurring in 06/242 (2.4%) of the Child-A, and in 05/15 (33.3%) of the Child-B patients. In conclusion, the treatment of patients with cirrhosis due to HCV with PEG-IFN and RBV shows a low SVR rate and a high mortality, especially in patients with liver dysfunction. PMID:27253739

    The main activity of the Houillères du Bassin de Lorraine (Lorraine Collieries), employing 23,000 operatives and executives, is coalmining. The coke production is carried out by two coke oven plants with a workforce of respectively 747 and 552 workers. The coal coking process entails the emission of noxious products such as polycyclic aromatic hydrocarbons (PAH) from the ovens. The influence of occupational exposure on mortality due to respiratory cancers, and particularly to lung and upper respiratory and alimentary tracts cancer, was investigated among a cohort of 534 male workers from the two coke oven plants who had retired from work between 1963 and 1982. The job history of each subject has been precisely reconstructed by indicating the duration of exposure on the ovens, close to the ovens, and in maintenance occupations. The cohort mortality has been analysed according to the method of indirect standardisation with reference to the French male population and by a case-control study concerning the consumption of tobacco per cohort. The mortality due to lung cancer is 2.51 times higher than expected. This excess of mortality differs, but not significantly, between the two coke oven plants (standardised mortality ratio equals 3.05 and 1.75 respectively). It is not significantly higher among subjects exposed for more than five years, directly exposed on the ovens or working near the ovens or at maintenance occupations on the ovens (SMR = 2.78), than among those exposed for less than five years (SMR = 2.35) or those not exposed at all. Even taking into account the excess of mortality due to lung cancers in the Moselle district (1.6 time that of France), the excess of lung cancers does not seem to be explained by the regional factor, or by tobacco and alcohol consumption. Although no significant relation was offered between lung cancer and the duration of exposure to PAH, even when taking smoking habits into account, the carcinogenic role of occupational nuisances

    Air pollution is an important environmental factor associated with health impacts in Europe and considerable resources are used to reduce exposure to air pollution through emission reductions. These reductions will have non-linear effects on exposure due, e.g., to interactions between climate and atmospheric chemistry. By using an integrated assessment model, we quantify the effect of changes in climate, emissions and population demography on exposure and health impacts in Europe. The sensitivity to the changes is assessed by investigating the differences between the decades 2000–2009, 2050–2059 and 2080–2089. We focus on the number of premature deaths related to atmospheric ozone, Secondary Inorganic Aerosols and primary PM. For the Nordic region we furthermore include a projection on how population exposure might develop due to changes in building stock with increased energy efficiency. Reductions in emissions cause a large significant decrease in mortality, while climate effects on chemistry and emissions only affects premature mortality by a few percent. Changes in population demography lead to a larger relative increase in chronic mortality than the relative increase in population. Finally, the projected changes in building stock and infiltration rates in the Nordic indicate that this factor may be very important for assessments of population exposure in the future.

    An association between health and socio-economic status is well known. Based on international and national studies, the aims of this study were to develop a multi-dimensional index at the municipality level, to provide information about socio-economic deprivation in Hungary and to investigate the association between socio-economic status and the spatial distribution of premature mortality due to diseases of the circulatory system. Seven municipality level socio-economic indicators were used from the National Information System of Spatial Development (income, low qualification, unemployment, one-parent families, large families, density of housing and car ownership). After normalisation and standardisation, indicator weights were evaluated using factor analysis. A risk analysis study was conducted using the Rapid Inquiry Facility software to evaluate the association between deprivation and the spatial distribution of premature mortality due to diseases of the circulatory system for the years 1998-2004. Areas of significantly high deprivation were identified in the northeastern, eastern and southwestern parts of Hungary. A statistically significant association was found between premature cardiovascular mortality and deprivation status in both genders. The Deprivation Index is the first composite index at the municipality level in Hungary and includes key factors that affect socio-economic status. The identified association highlighted the fact that inequalities in socio-economic status may reflect the spatial distribution of health status in a population. The results can be used to inform prevention strategies and help plan local health promotion programs aimed at reducing health inequalities. PMID:20199838

    Gross pathology due to tuberculosis can be established experimentally in brushtail possums (Trichosurus vulpecula) within 7 weeks of injection of virulent Mycobacterium bovis into subcutaneous connective tissues of the peripheral limbs. This pathology involves lymphadenomegaly and development of gross lesions in peripheral lymph nodes, with subsequent gross lesions in the lungs and reticuloendothelial organs. Using this artificial infection model, we here assessed the mortality rate for possums in the wild, to provide new information on the likely survival period for New Zealand's major wildlife host. Possums were trapped and inoculated with <50 CFU of M. bovis, then fitted with mortality signal emitting radio tracking collars, released and re-tracked for 6 months. Possum survival probability was 89% up to 12 weeks post-injection (p.i.), but cumulative mortality was rapid from then on. The median survival period, based on study of 38 possums, was 18 weeks p.i.; this corresponds with a predicted time interval of 11 weeks between first presentation of TB as palpable lymphadenomegaly and death for an average possum, shorter than period values currently used in possum TB epidemiological modelling. We also examined gross pathology in 11 possums by post mortem necropsy, and confirmed lymphadenomegaly and tuberculous lesions at 7 and 12 weeks p.i. Extra-peripheral gross lesions were more frequent among possums at 12 weeks p.i. than at 7 weeks, while the occurrence of lung lesions (the most likely cause of disease-induced mortality) was apparent in animals at 12 weeks but not at 7 weeks p.i. Our results suggest that the time course of TB from development of gross lesions to mortality may be shorter than previously estimated from field studies of naturally tuberculous possums.

    Therapy with oral anticoagulants (OACs) is a risk factor for cerebral hemorrhage (CH). Although different studies have been undertaken to investigate the timing of the onset of major cardiovascular events, no data exist on temporal patterns of the onset of CH in subjects treated with OACs. The aim of this study is to evaluate the timing of CH in patients treated with OACs. All patients who developed CH under OACs therapy and admitted to 28 Italian Emergency Departments (EDs) between September 2011 and July 2013 were enrolled. Age, sex, time and location of the hemorrhagic lesion, type of the bleeding events (idiopathic or post-traumatic), anticoagulant therapy (warfarin or new oral anticoagulants - NOAs) and time of ED admission (i.e., hour, day, month and season) were recorded. Five hundred and seventeen patients (63.2% male aged 80 ± 7.9 yrs) with CH were involved. Warfarin was taken by 494 patients (95.6%), and NOAs by 23 (4.4%). In-hospital mortality (IHM) was recorded in 208 cases (40.2%). Cosinor analysis showed a peak of CH arrival between 12:00 and 14:00 h both in the whole population (PR 73.9%, p = 0.002) and the male subgroup (PR 65.2%, p = 0.009), whereas females showed an anticipated morning peak between 08:00 and 10:00 h (PR 65.7%, p = 0.008). A further analysis between idiopathic and post-traumatic CH confirmed the presence of a 24 h pattern with a peak between 12:00 and 14:00 h (PR 58.5%, p = 0.019) and between 08:00 and 10:00 h (PR80.1%, p < 0.001) for idiopathic events and post-traumatic hemorrhages, respectively. Moreover, a seasonal winter peak was identified for idiopathic forms (PR 74%, p = 0.035), and a summer peak for post-traumatic forms (PR 77%, p = 0.025). The present study suggests the presence of a temporal pattern of ED arrivals in CH patients treated with OACs. PMID:26852790

    Premature death is a serious public health concern. The primary objective of this study was to examine premature deaths in terms of potential years of life lost (PYLL) in a cohort of 4817 treatment-seeking illicit drug users. Clients' data were linked to the Finnish national cause-of-death register and the follow-up period ranged from 31 January 1997 to 31 December 2010. PYLL before 70 years was calculated for all deaths and cause-specific deaths by gender. We observed 496 deaths (417 males and 79 females) at the end of 2010. The mean age at death was 33.8 years, 34.3 years for males (range 18-68) and 31.4 years for females (range 16-53). Overall, 17,951 life years were lost; 14,898 among males and 3053 among females. The overall PYLL rate for males was more than twice that of females (513.0/1000 vs. 243.7/1000 person-years) but the mean PYLL was higher in females than males (38.6 vs. 35.7 years). Of the total PYLL, 34.8 % was due to accidental overdose, and 24.0 % to suicide. In both genders, accidental overdose and suicide were the two top-ranking causes of PYLL. Premature deaths among drug users are a potential loss to the society. Our findings suggest that measures targeting accidental overdose and suicide are top priorities for reducing preventable loss of life. PMID:25967278

    Particulate matter with a diameter of less than 2.5 μm, known as PM2.5, can affect human health, especially in elderly people. Because of the imminent aging of society in the near future in most developed countries, the human health impacts of PM2.5 must be evaluated. In this study, we used a global-to-regional atmospheric transport model to simulate PM2.5 in Japan with a high-resolution stretched grid system (∼10 km for the high-resolution model, HRM) for the present (the 2000) and the future (the 2030, as proposed by the Representative Concentrations Pathway 4.5, RCP4.5). We also used the same model with a low-resolution uniform grid system (∼100 km for the low-resolution model, LRM). These calculations were conducted by nudging meteorological fields obtained from an atmosphere-ocean coupled model and providing emission inventories used in the coupled model. After correcting for bias, we calculated the excess mortality due to long-term exposure to PM2.5 among the elderly (over 65 years old) based on different minimum PM2.5 concentration (MINPM) levels to account for uncertainty using the simulated PM2.5 distributions to express the health effect as a concentration-response function. As a result, we estimated the excess mortality for all of Japan to be 31,300 (95% confidence intervals: 20,700 to 42,600) people in 2000 and 28,600 (95% confidence intervals: 19,000 to 38,700) people in 2030 using the HRM with a MINPM of 5.8 μg/m3. In contrast, the LRM resulted in underestimates of approximately 30% (for PM2.5 concentrations in the 2000 and 2030), approximately 60% (excess mortality in the 2000) and approximately 90% (excess mortality in 2030) compared to the HRM results. We also found that the uncertainty in the MINPM value, especially for low PM2.5 concentrations in the future (2030) can cause large variability in the estimates, ranging from 0 (MINPM of 15 μg/m3 in both HRM and LRM) to 95,000 (MINPM of 0 μg/m3 in HRM) people.

    Background The mortality prediction represents a key factor in the managing of elderly hospitalized patients. Since in older subjects mortality results from a combination of biological, functional, nutritional, psychological and environmental factors, a Multidimensional Prognostic Index (MPI) that predict short- and long-term mortality based on a standardized comprehensive geriatric assessment (CGA) has recently been developed and validated. Objective This study compares the accuracy in predicting the mortality of the MPI with a modified version of the MPI (m-MPI) that included the Mini Nutritional Assessment-Short Form (MNA-SF) instead of the standard MNA. Design This prospective study with a one-year follow-up included 4088 hospitalized patients aged 65 years and older. A standardized CGA that included information on functional (Activities of Daily Living, ADL and Instrumental-ADL), cognitive (Short Portable Mental Status Questionnaire), risk of pressure sore (Exton-Smith Scale), comorbidities (CIRS Index), medications, living status and nutritional status (MNA and MNA-SF) was used to calculate the MPI using a previously validated algorithm. Results Higher MPI values were significantly associated with higher mortality rates with a close agreement between the estimated and the observed mortality both after 1-month (MPI1=2.8% versus m-MPI1=2.8%, p=0.946; MPI2=8.9% versus m-MPI2=9%, p=0.904; MPI3=21.9% versus m-MPI3=21.9, p=0.978) and 1-year of follow-up (MPI1=10.8% versus m-MPI1=10.5%, p=0.686; MPI2=27.3% versus m-MPI2=28%, p=0.495; MPI3=52.8% versus m-MPI3=52.7%, p=0.945). The estimated areas under the receiver operating characteristics (ROC) curves suggested a clinically negligible difference between the two indices. Conclusion The m-MPI is as sensitive as the MPI in stratifying hospitalized elderly patients into groups at varying risk of short- and long-term mortality, but with fewer items. PMID:21369662

    Air pollution is a major environmental risk to health. In this study, short-term premature mortality due to particulate matter equal to or less than 2.5 μm in aerodynamic diameter (PM2.5) in the Yangtze River Delta (YRD) is estimated by using a PC-based human health benefits software. The economic loss is assessed by using the willingness to pay (WTP) method. The contributions of each region, sector and gaseous precursor are also determined by employing brute-force method. The results show that, in the YRD in 2010, the short-term premature deaths caused by PM2.5 are estimated to be 13,162 (95% confidence interval (CI): 10,761-15,554), while the economic loss is 22.1 (95% CI: 18.1-26.1) billion Chinese Yuan. The industrial and residential sectors contributed the most, accounting for more than 50% of the total economic loss. Emissions of primary PM2.5 and NH3 are major contributors to the health-related loss in winter, while the contribution of gaseous precursors such as SO2 and NOx is higher than primary PM2.5 in summer.

    This study aimed to investigate the impact of dust storms on short-term mortality in Kuwait. We analyzed respiratory and cardiovascular mortality as well as all-cause mortality in relation to dust storm events over a 5-year study period, using data obtained through a population-based retrospective ecological time series study. Dust storm days were identified when the national daily average of PM10 exceeded 200 μg/m3. Generalized additive models with Poisson link were used to estimate the relative risk (RR) of age-stratified daily mortality associated with dust events, after adjusting for potential confounders including weather variables and long-term trends. There was no significant association between dust storm events and same-day respiratory mortality (RR = 0.96; 95 %CI 0.88-1.04), cardiovascular mortality (RR = 0.98; 95 %CI 0.96-1.012) or all-cause mortality (RR = 0.99; 95 %CI 0.97-1.00). Overall our findings suggest that local dust, that most likely originates from crustal materials, has little impact on short-term respiratory, cardiovascular or all-cause mortality.

    Background Conflicting results on the relationship between the hardness of drinking water and mortality related to ischemic heart disease (IHD) or stroke have been reported. Objectives We investigated the possible association between tap water calcium or magnesium concentration and total hardness and IHD mortality or stroke mortality. Methods In 1986, a cohort of 120,852 men and women aged 55–69 years provided detailed information on dietary and other lifestyle habits. Follow-up for mortality until 1996 was established by linking data from the Central Bureau of Genealogy and Statistics Netherlands. We calculated tap water hardness for each postal code using information obtained from all pumping stations in the Netherlands. Tap water hardness was categorized as soft [< 1.5 mmol/L calcium carbonate (CaCO3)], medium hard (1.6–2.0 mmol/L CaCO3), and hard (> 2.0 mmol/L CaCO3). The multivariate case-cohort analysis was based on 1,944 IHD mortality and 779 stroke mortality cases and 4,114 subcohort members. Results For both men and women, we observed no relationship between tap water hardness and IHD mortality [hard vs. soft water: hazard ratio (HR) = 1.03; 95% confidence interval (CI), 0.85–1.28 for men and HR = 0.93; 95% CI, 0.71–1.21 for women) and stroke mortality (hard vs. soft water HR = 0.90; 95% CI, 0.66–1.21 and HR = 0.86; 95% CI, 0.62–1.20, respectively). For men with the 20% lowest dietary magnesium intake, an inverse association was observed between tap water magnesium intake and stroke mortality (HR per 1 mg/L intake = 0.75; 95% CI, 0.61–0.91), whereas for women with the 20% lowest dietary magnesium intake, the opposite was observed. Conclusions We found no evidence for an overall significant association between tap water hardness, magnesium or calcium concentrations, and IHD mortality or stroke mortality. More research is needed to investigate the effect of tap water magnesium on IHD mortality or stroke mortality in subjects with low dietary

    Acute worsening heart failure (WHF) is seen in a sizable portion of patients hospitalized for heart failure, and is increasingly being recognized as an entity that is associated with an adverse in-hospital course. WHF is generally defined as worsening heart failure symptoms and signs requiring an intensification of therapy, and is reported to be seen in anywhere from 5% to 42% of heart failure admissions. It is difficult to ascertain the exact epidemiology of WHF due to varying definitions used in the literature. Studies indicate that WHF cannot be precisely predicted on the basis of baseline variables assessed at the time of admission. Recent data suggest that some experimental therapies may reduce the risk of development of WHF among hospitalized heart failure patients, and this is associated with a reduction in risk of subsequent post-discharge cardiovascular mortality. In this respect, WHF holds promise as a endpoint for acute heart failure clinical trials to better elucidate the benefit of targeted novel therapies. Better understanding of the pathophysiology and a consensus on the definition of WHF will further improve our epidemiological and clinical understanding of this entity. PMID:26235192

    Coronary disease is a major cause of death and disability. From 1975 to 2000, coronary mortality was reduced by half. Better treatments and reduction of risk factors are the main causes. This phenomenon is observed in most developed countries, but mortality from coronary heart disease continues to increase in developing countries. In-hospital mortality of ST elevation myocardial infarction (STEMI) is in the range of 7 to 10% in registries. In infarction without ST segment elevation (NSTEMI), in-hospital mortality is around 5%. More recent studies found a similar in-hospital mortality for STEMI and NSTEMI. Because of patient selection and monitoring, mortality in clinical trials is much lower. After adjustment for the extent of coronary disease, age, risk factors, history of myocardial infarction, the excess mortality observed in women is fading. Many clinical, biological and laboratory parameters are associated with mortality in myocardial infarction. They refer to the immediate risk of death (ventricular rhythm disturbances, shock…), the extent of infarction (number of leads with ST elevation on the ECG, release of biomarkers, ejection fraction…), the presence of heart failure, the failure of reperfusion and the patient's baseline risk (age, renal function…). Risk scores, and more specifically the GRACE risk score, synthesize these different markers to predict the risk of death in a given patient. However, their use for the treatment of myocardial only concerns NSTEMI. Only a limited number of mechanical or pharmacological interventions reduces mortality of heart attack. The main benefits are observed with reperfusion by thrombolysis or primary angioplasty in STEMI, aspirin, heparin, beta-blockers, angiotensin converting enzyme inhibitors. Some medications such as bivalirudin and fondaparinux reduce mortality by decreasing the incidence of hemorrhagic complications. The guidelines classify interventions according to their benefit and especially their ability

    Approximately 15% of patients with acute coronary syndromes (ACS) develop posttraumatic stress disorder (PTSD) due to their ACS event. We assessed whether ACS-induced PTSD symptoms increase risk for major adverse cardiac events (MACE) and all-cause mortality (ACM) in an observational cohort study of 247 patients (aged 25-93 years; 45% women) hospitalized for an ACS at one of 3 academic medical centers in New York and Connecticut between November 2003 and June 2005. Within 1 week of admission, patient demographics, Global Registry of Acute Coronary Events risk score, Charlson comorbidity index, left ventricular ejection fraction, and depression status were obtained. At 1-month follow-up, ACS-induced PTSD symptoms were assessed with the Impact of Events Scale-Revised. The primary endpoint was combined MACE (hospitalization for myocardial infarction, unstable angina or urgent/emergency coronary revascularization procedures) and ACM, which were actively surveyed for 42 months after index event. Thirty-six (15%) patients had elevated intrusion symptoms, 32 (13%) elevated avoidance symptoms, and 21 (9%) elevated hyperarousal symptoms. Study physicians adjudicated 21 MACEs and 15 deaths during the follow-up period. In unadjusted Cox proportional hazards regression analyses, and analyses adjusted for sex, age, clinical characteristics and depression, high intrusion symptoms were associated with the primary endpoint (adjusted hazard ratio, 3.38; 95% confidence interval, 1.27-9.02; p = .015). Avoidance and hyperarousal symptoms were not associated with the primary endpoint. The presence of intrusion symptoms is a strong and independent predictor of elevated risk for MACE and ACM, and should be considered in the risk stratification of ACS patients. PMID:21807378

    Prebiotics consisting of resistant starch may alter intestinal ecology, thus modulating inflammation and increasing intestinal health through increased cecal production of short-chain fatty acids (SCFA). Probiotics may directly alter the intestinal microbiome, resulting in the same effects. We hypothesize that adding prebiotics and probiotics to feed may protect the gut of young chicks under stress. Studies 1, 2, and 3 evaluated treatments in a cold stress (CS) and Escherichia coli (EC) oral challenge to 430 day-old broiler chicks for 3 wk. In study 1, prebiotics were administered as 15% of the diet during the first week only and consisted of the following: Hi-Maize resistant starch (HM), potato starch (PS), or raw potato (RP). In studies 2 and 3, the PS treatment was identical to study 1, and an additional probiotic treatment (PRO) was administered in feed and water. In study 1, PS protected BW during the first week and decreased the mortality of CS/EC-challenged birds during the first week and wk 3, while RP decreased the mortality of warm-brooded birds challenged with EC during the first week. In study 2, PS decreased and PRO increased the main effect mean (MEM) of the first week BW. PS and PRO numerically decreased the feed conversion ratio (FCR) by 23 and 29 points, respectively, in CS/EC-challenged birds with no effects on mortality. In study 3, PS decreased and PRO increased the first week and wk 3 MEM BW. PS numerically increased FCR by 16 points, while PRO decreased FCR by 2 points. Both PS and PRO tended to increase overall mortality, and PRO significantly increased mortality in the CS/EC challenge. These results suggest that the effects of PS may be too variable in this challenge model for further study; however, the PRO treatment improved production values and may have potential as an alternative to antibiotics during the first weeks after hatch.

  13. Lessons from history--maternal and infant mortality.

    PubMed

    1989-07-15

    Historical analysis of trends in infant and maternal mortality rates reveal different patterns and factors that influence them. Recent international and urban-rural differences in trends, associations with population density and the influence of parental social class and income has led to questioning the long accepted interpretation of the sharp decline of infant mortality in Britain (at the turn of the century) as due to such measures as pure water supplies, sewage disposal and pasteurization of milk. Several authors now believe that direct control of fertility influenced parity and birth spacing, with all other factors contributing to the decline in infant mortality. While the drop in infant mortality rates can be attributable to social and environmental influence, trends in maternal mortality differ considerably. Even though high maternal mortality has often been associated with areas of poverty, such a link has been indirect; the determining factor is the place of delivery, and the skill and care of the birth attendant. The decline in maternal mortality rates began by the mid-1930's and have been halved every 10 years since. National concerns due to high rates of maternal mortality led to different organizational solutions. The US adopted a specialist obstetrician/hospital-based delivery system; the Netherlands combined midwives with home delivery; New Zealand trained midwives but with delivery in hospitals, and Britain included specialized obstetricians with better training of midwives and general practitioners. All of these variations had no effect on mortality rates. The decline is attributed to the use of sulphonamids followed by penicillin and improvements in medical management. In a recent publication entitled "Working for Patients", mortality rates continue to remain the outcome measures to be used universally while infant mortality rates are considered crude and not amenable to health interventions.

    Background Despite some evidences about protective or triggering role of opium use in patients with coronary artery disease, the exact role of opium is still under question. The current study aimed to address the relation of opium dependence on the severity and extension of myocardial infarction (MI) and its related mortality. Methods The study population consisted of 460 consecutive patients (239 opium addicts and 221 non-addicts) with first acute MI. Study information was extracted from hospital recorded files as well as face to face interview. Findings In-hospital mortality in opium addicted patients was numerically lower than another group (5.4% versus 8.2%), but this difference was not statistically significant. Regarding types of MI, anterior wall MI was higher in non-addicted patients than addicts (36.4% versus 26.4%). Among patients with anterior wall MI, early mortality was significantly higher in non-addicted compared to addicted subjects (20.0% versus 7.9% P = 0.043). The main associated factors of in-hospital mortality due to acute MI in addicts were advanced age and family history of coronary artery disease and in non-addicts were advanced age and hypertension. Conclusion In current study total in-hospital mortality was not different between opium addicted and non-addicted groups but opium may reduce the occurrence of anterior wall MI and its related early mortality.

    Background Analysing the observed differences for incidence or mortality of a particular disease between two different situations (such as time points, geographical areas, gender or other social characteristics) can be useful both for scientific or administrative purposes. From an epidemiological and public health point of view, it is of great interest to assess the effect of demographic factors in these observed differences in order to elucidate the effect of the risk of developing a disease or dying from it. The method proposed by Bashir and Estève, which splits the observed variation into three components: risk, population structure and population size is a common choice at practice. Results A web-based application, called RiskDiff has been implemented (available at http://rht.iconcologia.net/riskdiff.htm), to perform this kind of statistical analyses, providing text and graphical summaries. Code from the implemented functions in R is also provided. An application to cancer mortality data from Catalonia is used for illustration. Conclusions Combining epidemiological with demographical factors is crucial for analysing incidence or mortality from a disease, especially if the population pyramids show substantial differences. The tool implemented may serve to promote and divulgate the use of this method to give advice for epidemiologic interpretation and decision making in public health. PMID:20021655

    Abstract Cancer is currently in the spotlight due to their heavy responsibility as main cause of death in both developed and developing countries. Analysis of the epidemiological situation is required as a support tool for the planning of public health measures for the most vulnerable groups. We analyzed cancer mortality trends in Brazil and geographic regions in the period 1996 to 2010 and calculate mortality predictions for the period 2011 to 2030. This is an epidemiological, demographic-based study that utilized information from the Mortality Information System on all deaths due to cancer in Brazil. Mortality trends were analyzed by the Joinpoint regression, and Nordpred was utilized for the calculation of predictions. Stability was verified for the female (annual percentage change [APC] = 0.4%) and male (APC = 0.5%) sexes. The North and Northeast regions present significant increasing trends for mortality in both sexes. Until 2030, female mortality trends will not present considerable variations, but there will be a decrease in mortality trends for the male sex. There will be increases in mortality rates until 2030 for the North and Northeast regions, whereas reductions will be verified for the remaining geographic regions. This variation will be explained by the demographic structure of regions until 2030. There are pronounced regional and sex differences in cancer mortality in Brazil, and these discrepancies will continue to increase until the year 2030, when the Northeast region will present the highest cancer mortality rates in Brazil.

    During April, 2004, 40 sick and dead southern sea otters (Enhydra lutris nereis) were recovered over 18 km of coastline near Morro Bay, California. This event represented the single largest monthly spike in mortality ever recorded during 30 years of southern sea otter stranding data collection. Because of the point-source nature of the event and clinical signs consistent with severe, acute neurological disease, exposure to a chemical or marine toxin was initially considered. However, detailed postmortem examinations revealed lesions consistent with an infectious etiology, and further investigation confirmed the protozoan parasite Sarcocystis neurona as the underlying cause. Tissues from 94% of examined otters were PCR-positive for S. neurona, based on DNA amplification and sequencing at the ITS-1 locus, and 100% of tested animals (n = 14) had elevated IgM and IgG titers to S. neurona. Evidence to support the point-source character of this event include the striking spatial and temporal clustering of cases and detection of high concentrations of anti-S. neurona IgM in serum of stranded animals. Concurrent exposure to the marine biotoxin domoic acid may have enhanced susceptibility of affected otters to S. neurona and exacerbated the neurological signs exhibited by stranded animals. Other factors that may have contributed to the severity of this epizootic include a large rainstorm that preceded the event and an abundance of razor clams near local beaches, attracting numerous otters close to shore within the affected area. This is the first report of a localized epizootic in marine wildlife caused by apicomplexan protozoa. PMID:20615616

    Electrocution by power lines is one of the main causes of non-natural mortality in birds of prey. In an area in central Spain, we surveyed 6304 pylons from 333 power lines to determine electrocution rates, environmental and design factors that may influence electrocution and the efficacy of mitigation measures used to minimise electrocution cases. A total of 952 electrocuted raptors, representing 14 different species, were observed. Electrocuted raptors were concentrated in certain areas and the environmental factors associated with increased electrocution events were: greater numbers of prey animals; greater vegetation cover; and shorter distance to roads. The structural elements associated with electrocutions were shorter strings of insulators, one or more phases over the crossarm, cross-shaped design and pylon function. Of the 952 carcasses found, 148 were eagles, including golden eagle (Aquila chrysaetos), Spanish imperial eagle (Aquila adalberti) and Bonelli's eagle (Aquila fasciata). Electrocuted eagles were clustered in smaller areas than other electrocuted raptors. The factors associated with increased eagle electrocution events were: pylons function, shorter strings of insulators, higher slopes surrounding the pylon, and more numerous potential prey animals. Pylons with increased string of insulators had lower raptor electrocution rates than unimproved pylons, although this technique was unsuccessful for eagles. Pylons with cable insulation showed higher electrocution rates than unimproved pylons, both for raptors and eagles, despite this is the most widely used and recommended mitigation measure in several countries. To optimize the application of mitigation measures, our results recommend the substitution of pin-type insulators to suspended ones and elongating the strings of insulators. PMID:22140549

    In October 2009, during a Karenia brevis red tide along the Texas coast, millions of dead fish washed ashore along the 113-km length of Padre Island National Seashore (PAIS). Between November 2009 and January 2010, at least 12 coyotes (Canis latrans) and three domestic dogs (Canis familiaris) died or were euthanized at PAIS or local veterinary clinics because of illness suspected to be related to the red tide. Another red tide event occurred during autumn 2011 and, although fewer dead fish were observed relative to the 2009 event, coyotes again were affected. Staff at PAIS submitted carcasses of four coyotes and one domestic dog from November 2009 to February 2010 and six coyotes from October to November 2011 for necropsy and ancillary testing. High levels of brevetoxins (PbTxs) were measured by enzyme-linked immunosorbent assay in seven of the coyotes and the dog, with concentrations up to 634 ng PbTx-3 eq/g in stomach contents, 545 ng PbTx-3 eq/g in liver, 195 ng PbTx-3 eq/g in kidney, and 106 ng PbTx-3 eq/mL in urine samples. Based on red tide presence, clinical signs, and postmortem findings, brevetoxicosis caused by presumptive ingestion of toxic dead fish was the likely cause of canid deaths at PAIS. These findings represent the first confirmed report of terrestrial mammalian wildlife mortalities related to a K. brevis bloom. The implications for red tide impacts on terrestrial wildlife populations are a potentially significant but relatively undocumented phenomenon. PMID:24502723

    In 1951 the WHO Regional Office for Europe as a part of its long-term activities in child health initiated plans for a meeting between paediatricians and child psychiatrists, at which they could discuss their respective roles and the co-ordination of their work. Early in 1953 an ad hoc committee was called together to discuss the possibility of holding a conference which would delineate the role of the paediatrician in the management of psychosomatic and behaviour disorders in young children. This committee, consisting of leading specialists in paediatrics and child psychiatry, under the chairmanship of Professor R. Debré (France), felt that any wider conference should be devoted to considering more fully the inter-relation of somatic and psychological processes in sick children, the respective roles of paediatricians and child psychiatrists in their treatment, and the working relations between the different disciplines responsible for the care of children. In order to avoid diffusion of effort, and to arrive as far as possible at practical conclusions, the study group that was subsequently convened in Stockholm concentrated on one important aspect of child care—the child in hospital.

  8. In-Hospital Ischemic Stroke

    PubMed Central

    2015-01-01

    Between 2.2% and 17% of all strokes have symptom onset during hospitalization in a patient originally admitted for another diagnosis or procedure. These in-hospital strokes represent a unique population with different risk factors, more mimics, and substantially worsened outcomes compared to community-onset strokes. The fact that these strokes manifest during the acute care hospitalization, in patients with higher rates of thrombolytic contraindications, creates distinct challenges for treatment. However, the best evidence suggests benefit to treating appropriately selected in-hospital ischemic strokes with thrombolysis. Evidence points toward a “quality gap” for in-hospital stroke with longer in-hospital delays to evaluation and treatment, lower rates of evaluation for etiology, and decreased adherence to consensus quality process measures of care. This quality gap for in-hospital stroke represents a focused opportunity for quality improvement. PMID:26288675

    In-hospital biliary complications (BCs) after liver transplantation (LT) are reported in up to 20% of patients and contribute to poor outcomes and increased costs. Existing single center outcome and cost analyses studies are limited in scope. This is a cross-sectional analysis of national data involving 7,967 patients transplanted between 2011–12 with the primary aim of determining the association between BCs and clinical outcomes and costs. Age, race, diagnosis, and severity of illness are associated with the development of BCs. BCs develop in 14.6% of LT recipients and have substantial implications for peri-operative outcomes, including length of hospital and ICU stay (27·9 vs 19·6 mean days, p<0·001 and 12·0 vs 8·3 mean days, p<0·001 respectively), in-hospital morbidity (39% vs 27%, p<0·001), 30-day readmissions (14·8% vs 11·2%, p<0·001), and in-hospital mortality (5·8% vs 4·0%, p<0·001). BCs contributed to a mean increase in in-hospital costs of $36,212 (p<0·001), due to increases in accommodations ($9,539, p<0·001), surgical services ($3,988, p<0·001), and pharmacy services ($8,445, p<0·001). BCs are a predominant etiology for in-hospital morbidity and mortality, while contributing significantly to the high cost of LT. Efforts should be focused on understanding salient and modifiable risk factors, while developing innovative strategies to reduce BCs. PMID:25319035

    The study examines effects of hot spells on cardiovascular disease (CVD) morbidity and mortality in the population of the Czech Republic, with emphasis on differences between ischaemic heart disease (IHD) and cerebrovascular disease (CD) and between morbidity and mortality. Daily data on CVD morbidity (hospital admissions) and mortality over 1994-2009 were obtained from national hospitalization and mortality registers and standardized to account for long-term changes as well as seasonal and weekly cycles. Hot spells were defined as periods of at least two consecutive days with average daily air temperature anomalies above the 95 % quantile during June to August. Relative deviations of mortality and morbidity from the baseline were evaluated. Hot spells were associated with excess mortality for all examined cardiovascular causes (CVD, IHD and CD). The increases were more pronounced for CD than IHD mortality in most population groups, mainly in males. In the younger population (0-64 years), however, significant excess mortality was observed for IHD while there was no excess mortality for CD. A short-term displacement effect was found to be much larger for mortality due to CD than IHD. Excess CVD mortality was not accompanied by increases in hospital admissions and below-expected-levels of morbidity prevailed during hot spells, particularly for IHD in the elderly. This suggests that out-of-hospital deaths represent a major part of excess CVD mortality during heat and that for in-hospital excess deaths CVD is a masked comorbid condition rather than the primary diagnosis responsible for hospitalization.

Hot spells were defined as periods of at least two consecutive days with average daily air temperature anomalies above the 95% quantile during June to August. Relative deviations of mortality and morbidity from the baseline were evaluated. Hot spells were associated with excess mortality for all examined cardiovascular causes (CVD, IHD and CD). The increases were more pronounced for CD than IHD mortality in most population groups, mainly in males. In the younger population (0-64 years), however, significant excess mortality was observed for IHD while there was no excess mortality for CD. A short-term displacement effect was found to be much larger for mortality due to CD than IHD. Excess CVD mortality was not accompanied by increases in hospital admissions and below-expected-levels of morbidity prevailed during hot spells, particularly for IHD in the elderly. This suggests that out-of-hospital deaths represent a major part of excess CVD mortality during heat and that for in-hospital excess deaths CVD is a masked comorbid condition rather than the primary diagnosis responsible for hospitalization.

    AIM: To assess the rate of infection, appropriateness of antimicrobial-therapy and mortality on intensive care unit (ICU). Special focus was drawn on patients with liver cirrhosis. METHODS: The study was approved by the local ethical committee. All patients admitted to the Internal Medicine-ICU between April 1, 2007 and December 31, 2009 were included. Data were extracted retrospectively from all patients using patient charts and electronic documentations on infection, microbiological laboratory reports, diagnosis and therapy. Due to the large hepatology department and liver transplantation center, special interest was on the subgroup of patients with liver cirrhosis. The primary statistical-endpoint was the evaluation of the influence of appropriate versus inappropriate antimicrobial-therapy on in-hospital-mortality. RESULTS: Charts of 1979 patients were available. The overall infection-rate was 53%. Multiresistant-bacteria were present in 23% of patients with infection and were associated with increased mortality (P < 0.000001). Patients with infection had significantly increased in-hospital-mortality (34% vs 17%, P < 0.000001). Only 9% of patients with infection received inappropriate initial antimicrobial-therapy, no influence on mortality was observed. Independent risk-factors for in-hospital-mortality were the presence of septic-shock, prior chemotherapy for malignoma and infection with Pseudomonas spp. Infection and mortality-rate among 175 patients with liver-cirrhosis was significantly higher than in patients without liver-cirrhosis. Infection increased mortality 2.24-fold in patients with cirrhosis. Patients with liver cirrhosis were at an increased risk to receive inappropriate initial antimicrobial therapy. CONCLUSION: The results of the present study report the successful implementation of early-goal-directed therapy. Liver cirrhosis patients are at increased risk of infection, mortality and to receive inappropriate therapy. Increasing burden are

    Background Studies on atrial fibrillation (AF) in decompensated heart failure (DHF) are scarce in Brazil. Objectives To determine AF prevalence, its types and associated factors in patients hospitalized due to DHF; to assess their thromboembolic risk profile and anticoagulation rate; and to assess the impact of AF on in-hospital mortality and hospital length of stay. Methods Retrospective, observational, cross-sectional study of incident cases including 659 consecutive hospitalizations due to DHF, from 01/01/2006 to 12/31/2011. The thromboembolic risk was assessed by using CHADSVASc score. On univariate analysis, the chi-square, Student t and Mann Whitney tests were used. On multivariate analysis, logistic regression was used. Results The prevalence of AF was 40%, and the permanent type predominated (73.5%). On multivariate model, AF associated with advanced age (p < 0.0001), non-ischemic etiology (p = 0.02), right ventricular dysfunction (p = 0.03), lower systolic blood pressure (SBP) (p = 0.02), higher ejection fraction (EF) (p < 0.0001) and enlarged left atrium (LA) (p < 0.0001). The median CHADSVASc score was 4, and 90% of the cases had it ≥ 2. The anticoagulation rate was 52.8% on admission and 66.8% on discharge, being lower for higher scores. The group with AF had higher in-hospital mortality (11.0% versus 8.1%, p = 0.21) and longer hospital length of stay (20.5 ± 16 versus 16.3 ± 12, p = 0.001). Conclusions Atrial fibrillation is frequent in DHF, the most prevalent type being permanent AF. Atrial fibrillation is associated with more advanced age, non-ischemic etiology, right ventricular dysfunction, lower SBP, higher EF and enlarged LA. Despite the high thromboembolic risk profile, anticoagulation is underutilized. The presence of AF is associated with longer hospital length of stay and high mortality. PMID:25352505

    Mexico's crude death rate has declined from 33/1000 in the early 20th century to about 6/1000 in 1985-87. Mortality declined sharply from 1640-60. more slowly from 1960-77, and rapidly again beginning around 1980. The explanation for the mortality decline lies both in advances in medical and health care and in economic growth of the country. The mortality declines in the late 1970s and early 1980s probably resulted primarily from extension of primary health care programs in rural areas. The infant mortality rate has declined from 288.6/1000 live births in 1900 to 73.8 in 1960 and 42 in 1986-87. At present 30% of deaths in Mexico are to children under 5, but little is known of the impact of the country's economic crisis on mortality in this age group. The strong mortality decline between 1950-70 was in the economically active age group of 15-64 years. Excess male mortality in this group reached a maximum in 1980: for each death of woman there were 150 male deaths. Between 1960-80 the rate of deaths due to infection, parasfitism, and respiratory disease declined by 5%, the rate of death from cancer remained almost unchanged, and the rate of death from cardiovascular diseases increased by 9%. Deaths from accidents, homicide, suicide, and other violence increased by 38%. Male general mortality rates were 25% higher than female in 1980. Mexican life expectancy increased from 49.6 years in 195 to 67 in 1987. Life expectancy was 65.6 for males and 71.7 for females. Average life expectancy was 69 for the more privileged social sectors and 56.7 for agricultural workers in 1965-79. The life expectancy of urban women was 3 years longer than that of rural women and 10.4 years longer than that of rural men. PMID:12158030

    Norovirus is one of the most common causes of acute gastroenteritis among children in developing countries. No data on the prevalence and genetic variability of norovirus are available for Pakistan, where early childhood mortality due to acute gastroenteritis is common. We tested 255 fecal specimens from children under 5 years of age hospitalized between April 2006 and March 2008 with severe acute gastroenteritis in five hospitals in the four largest cities in Pakistan for norovirus by real-time RT-PCR. Positive samples were further genotyped by conventional RT-PCR targeting the 5'-end of the capsid gene followed by sequencing of the positive PCR products. Overall, 41 (16.1%) samples tested positive for norovirus with an equal frequency in rotavirus-positive and rotavirus-negative samples. Nine (22%) samples were genogroup (G)I positive, 30 (73%) GII positive and two (5%) samples contained a mixture of GI and GII viruses. Sequence analyses demonstrated co-circulation of 14 norovirus genotypes including four GI genotypes (GI.3, GI.5, GI.7, GI.8) and 10 GII genotypes (GII.2, GII.3, GII.4, GII.5, GII.6, GII.7, GII.9, GII.13, GII.16, and GII.21). The most prevalent genotypes were GI.7 and GII.4 both causing 12.2% of the infections. This report confirms the presence of multiple norovirus genotypes in hospitalized children with acute gastroenteritis in Pakistan and a lack of clear predominance of GII.4 viruses. PMID:26175018

    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.

    Background Coronary artery bypass grafting currently is the best treatment for dialytic patients with multivessel coronary disease, but hospital morbidity and mortality related to procedure is still high. Objective Evaluate results and in-hospital outcomes of coronary artery bypass grafting in dialytic patients. Methods Retrospective unicentric study including 50 consecutive and not selected dialytic patients, who underwent coronary artery bypass grafting in a tertiary university hospital from 2007 to 2012. Results High prevalence of cardiovascular risk factors was observed (100% hypertensive, 68% diabetic and 40% dyslipidemic). There was no intra-operative death and 60% of the procedures were performed off-pump. There were seven (14%) in-hospital deaths. Postoperative infection, previous heart failure, cardiopulmonary bypass, abnormal ventricular function and surgical re-exploration were associated with increased mortality. Conclusion Coronary artery bypass grafting is feasible to dialytic patients although high in-hospital morbidity and mortality. It is necessary better understanding about metabolic aspects to plan adequate interventions. PMID:24270865

    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.

    Business intelligence (BI) is a worthwhile investment, and will play a significant role in hospital management in the near future. Implementation of BI is challenging and requires resources, skills, and a strategy, but enables management to have easy access to relevant analysis of data and visualization of important key performance indicators (KPI). Modern BI applications will help to overcome shortages of common "hand-made" analysis, save time and money, and will enable even managers to do "self-service" analysis and reporting. PMID:27514111

    There are a number of circumstances that may affect an individual's ability to maintain personal hygiene. Hospitalised patients, and in particular those who are bedridden, may become dependent on nursing staff to carry out their hygiene needs. Assisting patients to maintain personal hygiene is a fundamental aspect of nursing care. However, it is a task often delegated to junior or newly qualified staff. This article focuses on the principles of bed bathing patients in hospital, correct procedure and the importance of maintaining patient dignity and respect in clinical practice. PMID:18543852

    Objectives This study aimed to estimate the prevalence of diabetes mellitus (DM) in hospitalized patients with community-acquired pneumonia (CAP) and its impact on hospital length of stay and in-hospital mortality. Research design and methods We carried out a retrospective, nationwide register analysis of CAP in adult patients admitted to Portuguese hospitals between 2009 and 2012. Anonymous data from 157 291 adult patients with CAP were extracted from the National Hospital Discharge Database and we performed a DM-conditioned analysis stratified by age, sex and year of hospitalization. Results The 74 175 CAP episodes that matched the inclusion criteria showed a high burden of DM that tended to increase over time, from 23.7% in 2009 to 28.1% in 2012. Interestingly, patients with CAP had high DM prevalence in the context of the national DM prevalence. Episodes of CAP in patients with DM had on average 0.8 days longer hospital stay as compared to patients without DM (p<0.0001), totaling a surplus of 15 370 days of stay attributable to DM in 19 212 admissions. In-hospital mortality was also significantly higher in patients with CAP who have DM (15.2%) versus those who have DM (13.5%) (p=0.002). Conclusions Our analysis revealed that DM prevalence was significantly increased within CAP hospital admissions, reinforcing other studies’ findings that suggest that DM is a risk factor for CAP. Since patients with CAP who have DM have longer hospitalization time and higher mortality rates, these results hold informative value for patient guidance and healthcare strategies. PMID:27252873

    Mexico's infant mortality rate is estimated to have declined from 189 in 1930 to 129 in 1950 and 30 in 1995. The infant mortality rate has continued its decline despite the economic crisis of recent years. The use of oral rehydration therapy has reduced mortality from diarrhea, and the spread of family planning has reduced the numbers of births at high risk due to maternal age, parity, or short birth intervals. The types of causes of infant death have changed as the numbers have decreased. They can be grouped in ascending order according to the difficulty of prevention: diseases preventable by immunization, acute diarrhea, acute respiratory infections, perinatal disorders, and congenital anomalies. Over two-thirds of infant deaths recorded since 1950 have been due to these causes. Infectious diseases, including diarrhea, acute respiratory infections, and conditions preventable by immunization predominated as causes of infant mortality before 1930. As the epidemiological transition progresses, diseases preventable by immunization lose importance, and diarrhea and respiratory infections occupy the first two places, with perinatal disorders being third. Between 1980 and 1990, in Mexico, diarrhea and acute respiratory infections dropped to second and third place after perinatal disorders, with congenital anomalies in fourth place. In most developed countries, perinatal disorders and congenital anomalies are the two most frequent causes of death, while diarrhea and respiratory infections no longer appear in the top five. In 1995, the four main causes in Mexico in descending order were perinatal disorders, congenital anomalies, acute respiratory infections, and diarrhea. PMID:12158082

    We sought to characterize stroke management and outcomes in a postoperative population. By using the electronic medical records, we identified 39 patients suffering perioperative stroke after noncardiac and nonneurosurgical procedures for whom documentation of management and outcomes was available. Thirty-three strokes occurred during admission, whereas 6 occurred after discharge and were recognized upon return to the hospital. Perioperative stroke was associated with delayed recognition, infrequent intervention, and significant rates of morbidity and mortality, suggesting the need for improved screening and more rapid treatment. There may be disparities in care and outcomes between in-hospital and out-of hospital stroke patients, though further study is warranted. PMID:27490452

    Context: Medication errors are the most common types of medical errors in hospitals and leading cause of morbidity and mortality among patients. Aims: The aim of the present study was to assess the knowledge of healthcare professionals about medication errors in hospitals. Settings and Design: A self-administered questionnaire was distributed to randomly selected healthcare professionals in eight hospitals in Madinah, Saudi Arabia. Subjects and Methods: An 18-item survey was designed and comprised questions on demographic data, knowledge of medication errors, availability of reporting systems in hospitals, attitudes toward error reporting, causes of medication errors. Statistical Analysis Used: Data were analyzed with Statistical Package for the Social Sciences software Version 17. Results: A total of 323 of healthcare professionals completed the questionnaire with 64.6% response rate of 138 (42.72%) physicians, 34 (10.53%) pharmacists, and 151 (46.75%) nurses. A majority of the participants had a good knowledge about medication errors concept and their dangers on patients. Only 68.7% of them were aware of reporting systems in hospitals. Healthcare professionals revealed that there was no clear mechanism available for reporting of errors in most hospitals. Prescribing (46.5%) and administration (29%) errors were the main causes of errors. The most frequently encountered medication errors were anti-hypertensives, antidiabetics, antibiotics, digoxin, and insulin. Conclusions: This study revealed differences in the awareness among healthcare professionals toward medication errors in hospitals. The poor knowledge about medication errors emphasized the urgent necessity to adopt appropriate measures to raise awareness about medication errors in Saudi hospitals. PMID:27330261

    Pneumonia is a public health problem in the tropics, and the 7-valent pneumococcal conjugative vaccine (PCV-7) has been introduced in an effort to prevent the disease and therefore reduce childhood mortality. In Rwanda, PCV-7 was introduced in 2009, and we aimed to determine its impact on the rate of child hospitalization/mortality due to pneumonia. A retrospective survey was conducted on hospitalization rates and pediatric deaths between two periods, that is, before the introduction of PCV-7 (2007-2009) and after the introduction of PCV-7 (2010-2013) in Kabutare District Hospital. There was a 53% reduction in hospitalization, with a significant decline in in-hospital deaths between the two periods. There was also a significant correlation between vaccination coverage and decline in hospitalization rates between 2009 and 2013. We conclude that PCV-7 vaccine is associated with significant reduction in the rate of child hospitalization and mortality but more mechanistic studies are warranted to determine the immunological impact, especially in the context of coinfections and malnutrition.

    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

    Objective Dysnatremia is common in critically ill children due to disruption of hormonal homeostasis. Children with brain injury are at risk for SIADH, cerebral salt wasting and sodium losses due to externalized ventricular drain (EVD) placement. We hypothesized that among pediatric intensive care unit (PICU) patients managed with an EVD, hyponatremia is common, hyponatremia is associated with seizures and in-hospital mortality, and greater sodium fluctuations are associated with in-hospital mortality. Design Retrospective observational study Setting Tertiary care PICU Patients All pediatric patients treated in the PICU with an EVD from January 2005 to December 2009. Patients were identified by searching the physician order entry database for EVD orders. Hyponatremia was defined as the minimum sodium during patients’ EVD time and was categorized as mild (131-134 meq/L) or moderate-severe (≤130 meq/L). Magnitude of sodium fluctuation was defined as the difference between a patient’s highest and lowest sodium during the time in which an EVD was in use (up to 14 days). Seizure was defined as a clinically evident convulsion during EVD presence. A priori confounders were age, history of epilepsy, and EVD indication. Multivariable regression was performed to test the association between sodium derangements and outcomes. Interventions None. Measurements and Main Results Three hundred eighty patients were eligible. One hundred nine (29%) had mild hyponatremia, and 30 (8%) moderate-severe hyponatremia. Twenty eight (7%) patients had a seizure while hospitalized. Eighteen patients died (5%) prior to discharge. Survivors had a median daily sodium fluctuation of 1 [0, 5] vs non-survivors 9 [6, 11], (p< 0.001) and a median sodium fluctuation of 5 meq/L [interquartile range 2, 8] vs non-survivors 15 meq/L [9, 24] (p<0.001) during EVD management. After controlling for a priori covariates and potential confounders, hyponatremia was not associated with an increased odds of

    Background Recent studies have found substantial variation in hospital resource utilization by expired Medicare beneficiaries with chronic illnesses. By analyzing only expired patients, these studies cannot identify differences across hospitals in health outcomes like mortality. This study examines the association between mortality and resource utilization at the hospital level, when all Medicare beneficiaries hospitalized for heart failure are examined. Methods and Results 3,999 individuals hospitalized with a principal diagnosis of heart failure at six California teaching hospitals between January 1, 2001 and June 30, 2005 were analyzed with multivariate risk-adjustment models for total hospital days, total hospital direct costs, and mortality within 180-days after initial admission (“Looking Forward”). A subset of 1,639 individuals who died during the study period were analyzed with multivariate risk-adjustment models for total hospital days and total hospital direct costs within 180-days prior to death (“Looking Back”). “Looking Forward” risk-adjusted hospital means ranged from 17.0% to 26.0% for mortality, 7.8 to 14.9 days for total hospital days, and 0.66 to 1.30 times the mean value for indexed total direct costs. Spearman rank correlation coefficients were −0.68 between mortality and hospital days, and −0.93 between mortality and indexed total direct costs. “Looking Back” risk-adjusted hospital means ranged from 9.1 to 21.7 days for total hospital days and 0.91 to 1.79 times the mean value for indexed total direct costs. Variation in resource utilization site ranks between expired and all individuals were due to insignificant differences. Conclusions California teaching hospitals that used more resources caring for patients hospitalized for heart failure had lower mortality rates. Focusing only on expired individuals may overlook mortality variation as well as associations between greater resource utilization and lower mortality

    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

  12. Avoidable mortality from giving tranexamic acid to bleeding trauma patients: an estimation based on WHO mortality data, a systematic literature review and data from the CRASH-2 trial

    PubMed Central

    2012-01-01

    Background The CRASH-2 trial showed that early administration of tranexamic acid (TXA) safely reduces mortality in bleeding in trauma patients. Based on data from the CRASH-2 trial, global mortality data and a systematic literature review, we estimated the number of premature deaths that might be averted every year worldwide through the use of TXA. Methods We used CRASH-2 trial data to examine the effect of TXA on death due to bleeding by geographical region. We used WHO mortality data (2008) and data from a systematic review of the literature to estimate the annual number of in-hospital trauma deaths due to bleeding. We then used the relative risk estimates from the CRASH-2 trial to estimate the number of premature deaths that could be averted if all hospitalised bleeding trauma patients received TXA within one hour of injury, and within three hours of injury. Sensitivity analyses were used to explore the effect of uncertainty in the parameter estimates and the assumptions made in the model. Results There is no evidence that the effect of TXA on death due to bleeding varies by geographical region (heterogeneity p = 0.70). Based on WHO data and our systematic literature review, we estimate that each year worldwide there are approximately 400,000 in-hospital trauma deaths due to bleeding. If patients received TXA within one hour of injury then approximately 128,000 (uncertainty range [UR] ≈ 72,000 to 172,000) deaths might be averted. If patients received TXA within three hours of injury then approximately 112,000 (UR ≈ 68,000 to 148,000) deaths might be averted. Country specific estimates show that the largest numbers of deaths averted would be in India and China. Conclusions The use of TXA in the treatment of traumatic bleeding has the potential to prevent many premature deaths every year. A large proportion of the potential health gains are in low and middle income countries. PMID:22380715

    Outcomes of cardiopulmonary resuscitation (CPR) in hospitalized patients with ESRD requiring maintenance dialysis are unknown. Outcomes of in-hospital CPR in these patients were compared with outcomes in the general population using data from the Nationwide Inpatient Sample (NIS; 2005-2011). The study population included all adults (≥ 18 years old) from the general population and those with a history of ESRD. Baseline characteristics, in-hospital complications, and discharge outcomes were compared between the two groups. The effects of in-hospital CPR on mortality, length of stay, hospitalization charges, and discharge destination were analyzed. Yearly national trends in survival, discharge to home, and length of stay were also examined using the Cochran-Armitage trend test. During the study period, 56,069 patients with ESRD underwent in-hospital CPR compared with 323,620 patients from the general population. Unadjusted in-hospital mortality rates were higher in patients with ESRD (73.9% versus 71.8%, P<0.001) on univariate analysis. After adjusting for age, gender, and potential confounders, patients with ESRD had higher odds of mortality (odds ratio, 1.24; 95% confidence interval, 1.11 to 1.3; P<0.001). Survival after CPR improved in the year 2011 compared with 2005 (31% versus 21%, P<0.001). Multivariate analysis also revealed that a greater proportion of patients with ESRD who survived were discharged to skilled nursing facilities. In conclusion, outcomes after in-hospital CPR are improving in patients with ESRD but remain worse than outcomes in the general population. Patients with ESRD who survive are more likely to be discharged to nursing homes. PMID:25908784

    In a context in which sanitary institutions have transparency obligations toward authorities and patients, quality management and best practices--defined according to scientific standards--have become major concerns with respect to in-house management. While protocols and prescriptions are necessary for orienting work, they don't apply by themselves. Given that these various documents provide standardized and stabilized work descriptions, they contribute to hide what workers effectively do in unstable and variable situations in which numerous, sometimes contradictory, elements need to be simultaneously considered. In the present work, we follow this claim held by the French ergonomics stream and we consider the serious and irreducible gap between "prescribed work" and "real effective work". Such an understanding based on research evidence appears more adapted to professional realities and provides (valued) resources in nursing education. Based on information collected in three work analysis studies conducted by our team in hospital settings, we deepen these notions and their implication for practice and education. PMID:26510343

    Mobile technology has begun to change the landscape of the medical profession, with more than two-thirds of physicians regularly using smartphones. Smartphones have allowed health care professionals and the general public to communicate more efficiently, collect data, and facilitate clinical decision making. The methodology for this study was a qualitative literature review following a systematic approach of smartphone use among physicians in hospitals. Fifty-one articles were selected for this study based on inclusion criteria. The findings were classified and described into 7 categories: use of smartphone in obstetrics, pediatrics, surgery, internal medicine, radiology, and dermatology, which were chosen based on the documented use of smartphone application in different health care practices. A last section of patient safety and issues with confidentiality is also described. This study suggests that smartphones have been playing an increasingly important role in health care. Medical professionals have become more dependent upon medical smartphone applications. However, concerns of patient safety and confidentiality will likely lead to increased oversight of mobile device use by regulatory agencies and accrediting bodies. PMID:26506291

    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

    Abstract Importance: Over one-third of American adults (36%) are obese and more than two-thirds (69%) are overweight. The impact of obesity on hospitalization outcomes is not well understood. Objective: To examine the association between body mass index (BMI) and overall, cancer, chronic obstructive pulmonary disease (COPD), asthma, and cardiovascular disease (CVD)-specific in-hospital mortality; postsurgical complications; and hospital length of stay (LOS). Design: Cross-sectional study. Setting: Representative sample of US hospitals included in the Health Cost and Utilization Project Nationwide Inpatient Sample database. Participants: We obtained data for patients admitted with a primary diagnosis of cancer, COPD, asthma, and CVD. Main Outcome: In-hospital mortality, postsurgical complications, and hospital LOS. Results: A total of 800,417 patients were included in this analysis. A higher proportion of Blacks (26.8%; 12.5%) and Whites (23.3%; 8.7%) had BMI of 40 to 49.9 and ≥50, respectively, compared with Hispanics (20.4%; 7.3%). Compared with normal BMI patients, the odds of in-hospital mortality increased 3.6-fold (odds ratio [OR] 3.62, 95% confidence interval [CI]: 3.37–3.89) for preobese patients, 6.5-fold (OR: 6.52, 95% CI: 5.79–7.34) for patients with BMI: 30 to 31.9, 7.5-fold (OR: 7.57, 95% CI: 6.67–8.59) for patients with BMI: 34 to 35.9, and 1.6- fold (OR: 1.77, 95% CI: 1.56–1.79) for patients with BMI ≥ 50. Compared with normal BMI patients, preobese and overweight patients had shorter hospital stays (β preobese: −1.58, 95% CI: −1.63, −1.52); however, no clear trends were observed for postsurgical complications. Conclusions: The majority of hospitalized patients in this analysis had a BMI > 30, and higher BMI was associated with increased risk of mortality and longer hospital stay. PMID:27428218

    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

    Background Cefepime and ceftazidime are cephalosporins used for the treatment of serious gram-negative infections. These cephalosporins are used off-label in the setting of minimal safety data for young infants. Methods We identified all infants discharged from 348 neonatal intensive care units managed by the Pediatrix Medical Group between 1997 and 2012 who were exposed to either cefepime or ceftazidime in the first 120 days of life. We reported clinical and laboratory adverse events occurring in infants exposed to cefepime or ceftazidime and used multivariable logistic regression to compare the odds of seizures and death between the 2 groups. Results A total of 1761 infants received 13,293 days of ceftazidime, and 594 infants received 4628 days of cefepime. Laboratory adverse events occurred more frequently on days of therapy with ceftazidime compared with cefepime (373 vs. 341 per 1000 infant days, p<0.001). Seizure was the most commonly observed clinical adverse event, occurring in 3% of ceftazidime-treated infants and 4% of cefepime-treated infants (p=0.52). Mortality was similar between the ceftazidime and cefepime groups (5% vs. 3%, p=0.07). There was no difference in the adjusted odds of seizure (odds ratio [OR] = 0.96 [95% confidence interval, 0.89–1.03]) or the combined outcome of mortality or seizures (OR = 1.00 [0.96–1.04]) in infants exposed to ceftazidime vs. those exposed to cefepime. Conclusions In this cohort of infants, cefepime was associated with fewer laboratory adverse events than ceftazidime, although this may have been due to a significant difference in clinical exposures and severity of illness between the 2 groups. There was no difference in seizure risk or mortality between the 2 drugs. PMID:26376308

    Purpose - The purpose of this paper is to explore parenteral nutrition (PN) practices in hospital pharmacies of Kuwait and identify potential avenues for quality improvement in this service. Design/methodology/approach - A descriptive, qualitative study about PN practices was conducted from June 2012 to February 2013 in Kuwait. Data were collected via in-depth semi-structured interviews with the head total parenteral nutrition (TPN) pharmacists at seven hospitals using a developed questionnaire. The questionnaire obtained information about the PN service at each hospital including the existence of nutritional support teams (NSTs), PN preparation practices, quality controls and guidelines/protocols. The interviews were audio-recorded, transcribed verbatim and analyzed for content. Findings - Seven hospitals in Kuwait provided PN preparation service through TPN units within hospital pharmacies. Functional NSTs did not exist in any of these hospitals. All TPN units used paper-based standard PN order forms for requesting PN. The content of PN order forms and PN formulas labeling information were inconsistent across hospitals. Most of the prepared PN formulas were tailor-made and packed in single compartment bags. Quality controls used included gravimetric analysis and visual inspection of PN formulations, and less consistently reported periodic evaluation of the aseptic techniques. Six TPN units independently developed PN guidelines/protocols. Originality/value - This study revealed variations in many aspects of PN practices among the hospitals in Kuwait and provided recommendations to improve this service. Standardization of PN practices would enhance the quality of care provided to patients receiving PN and facilitate national monitoring. This can be accomplished through the involvement of healthcare professionals with expertise in nutrition support working within proactive NSTs. PMID:27298063

    Objectives: to identify the main causes for hospital admissions and deaths related to systemic arterial hypertension and diabetes mellitus (DM), and to analyze morbidity and mortality trends, in a municipality in São Paulo's countryside, by comparing two three-years periods, 2002 to 2004 and 2010 to 2012. Methods: cross-sectional study which used secondary data regarding deaths from the Information System on Mortality and concerning hospital admissions from the DataSus Hospital Information System. Univariate and multivariate statistical analyses were conducted. Results: from 2002 to 2012, 325,439 people were admitted to hospitals, 14.7% of them due to circulatory system diseases (CSD) and 0.7% due to DM. The deaths distributed as the following: 29,027 deaths (31.5%) were due to CSD; 8.06% due to cerebrovascular diseases (CVD); and 2.75% due to DM. There was a significant association between admittance and death causes and patients' gender and age in the three-year periods (p<0.001). The highest lethality in hospital admissions was found to be due to CVD (10%). That trend showed that mortality rates dropped, younger patients were admitted due to DM, and older patients were admitted due to CVD - they were more often females. Conclusion: the main causes for hospital admissions were the CSDs; main mortality causes were the CVDs in hypertensive and diabetic women. Those findings can back public policies which prioritize the promotion of health. PMID:26626008

    Background Despite the availability of guidelines for treatment of heart failure (HF), only a few studies have assessed how hospitals adhere to the recommended therapies. Objectives Compare the rates of adherence to the prescription of angiotensin-converting enzyme inhibitor or angiotensin II receptor blockers (ACEI/ARB) at hospital discharge, which is considered a quality indicator by the Joint Commission International, and to the prescription of beta-blockers at hospital discharge, which is recommended by national and international guidelines, in a hospital with a case management program to supervise the implementation of a clinical practice protocol (HCP) and another hospital that follows treatment guidelines (HCG). Methods Prospective observational study that evaluated patients consecutively admitted to both hospitals due to decompensated HF between August 1st, 2006, and December 31st, 2008. We used as comparing parameters the prescription rates of beta-blockers and ACEI/ARB at hospital discharge and in-hospital mortality. Results We analyzed 1,052 patients (30% female, mean age 70.6 ± 14.1 years), 381 (36%) of whom were seen at HCG and 781 (64%) at HCP. The prescription rates of beta-blockers at discharge at HCG and HCP were both 69% (p = 0.458), whereas those of ACEI/ARB were 83% and 86%, respectively (p = 0.162). In-hospital mortality rates were 16.5% at HCP and 27.8% at HCG (p < 0.001). Conclusion There was no difference in prescription rates of beta-blocker and ACEI/ARB at hospital discharge between the institutions, but HCP had lower in-hospital mortality. This difference in mortality may be attributed to different clinical characteristics of the patients in both hospitals. PMID:26815461

    Background: While several studies have analysed sex and socioeconomic differences in cancer incidence and mortality, sex differences in oncological health care have been seldom considered. Objective: To investigate sex based inequalities in hospital readmission among patients diagnosed with colorectal cancer. Design: Prospective cohort study. Setting: Hospital Universitary in L'Hospitalet (Barcelona, Spain). Participants: Four hundred and three patients diagnosed with colorectal between January 1996 and December 1998 were actively followed up until 2002. Main outcome measurements and methods: Hospital readmission times related to colorectal cancer after surgical procedure. Cox proportional model with random effect (frailty) was used to estimate hazard rate ratios and 95% confidence intervals of readmission time for covariates analysed. Results: Crude hazard rate ratio of hospital readmission in men was 1.61 (95% CI 1.21 to 2.15). When other significant determinants of readmission were controlled for (including Dukes's stage, mortality, and Charlson's index) a significant risk of readmission was still present for men (hazard rate ratio: 1.52, 95% CI 1.17 to 1.96). Conclusions: In the case of colorectal cancer, women are less likely than men to be readmitted to the hospital, even after controlling for tumour characteristics, mortality, and comorbidity. New studies should investigate the role of other non-clinical variable such as differences in help seeking behaviours or structural or personal sex bias in the attention given to patients.

    The relationship between risk of death following influenza A(H1N1)pdm09 infection and ethnicity and deprivation during the 2009/2010 pandemic period and the first post-pandemic season of 2010/2011 in England was examined. Poisson regression models were used to estimate the mortality risk, adjusted for age, gender, and place of residence. Those of non-White ethnicity experienced an increased mortality risk compared to White populations during the 2009/2010 pandemic [10·5/1000 vs. 6·0/1000 general population; adjusted risk ratio (RR) 1·84, 95% confidence interval (CI) 1·39-2·54] with the highest risk in those of Pakistani ethnicity. However, no significant difference between ethnicities was observed during the following 2010/2011 season. Persons living in areas with the highest level of deprivation had a significantly higher risk of death (RR 2·08, 95% CI 1·49-2·91) compared to the lowest level for both periods. These results highlight the importance of rapid identification of groups at higher risk of severe disease in the early stages of future pandemics to enable the implementation of optimal prevention and control measures for vulnerable populations.

    Summary Background Antenatal corticosteroids for pregnant women at risk of preterm birth are among the most effective hospital-based interventions to reduce neonatal mortality. We aimed to assess the feasibility, effectiveness, and safety of a multifaceted intervention designed to increase the use of antenatal corticosteroids at all levels of health care in low-income and middle-income countries. Methods In this 18-month, cluster-randomised trial, we randomly assigned (1:1) rural and semi-urban clusters within six countries (Argentina, Guatemala, India, Kenya, Pakistan, and Zambia) to standard care or a multifaceted intervention including components to improve identification of women at risk of preterm birth and to facilitate appropriate use of antenatal corticosteroids. The primary outcome was 28-day neonatal mortality among infants less than the 5th percentile for birthweight (a proxy for preterm birth) across the clusters. Use of antenatal corticosteroids and suspected maternal infection were additional main outcomes. This trial is registered with ClinicalTrials.gov, number NCT01084096. Findings The ACT trial took place between October, 2011, and March, 2014 (start dates varied by site). 51 intervention clusters with 47 394 livebirths (2520 [5%] less than 5th percentile for birthweight) and 50 control clusters with 50 743 livebirths (2258 [4%] less than 5th percentile) completed follow-up. 1052 (45%) of 2327 women in intervention clusters who delivered less-than-5th-percentile infants received antenatal corticosteroids, compared with 215 (10%) of 2062 in control clusters (p<0·0001). Among the less-than-5th-percentile infants, 28-day neonatal mortality was 225 per 1000 livebirths for the intervention group and 232 per 1000 livebirths for the control group (relative risk [RR] 0·96, 95% CI 0·87–1·06, p=0·65) and suspected maternal infection was reported in 236 (10%) of 2361 women in the intervention group and 133 (6%) of 2094 in the control group (odds ratio

    Women historically have a greater risk of operative mortality than men after coronary artery bypass grafting (CABG). There is paucity of contemporary data in gender outcomes of surgical revascularization and understanding modifiable factors that contribute to gender differences are critical for quality improvement and practice change. We, therefore, sought to examine whether the gender gap in CABG outcomes is closing in the contemporary era by conducting a retrospective analysis from the Nationwide Inpatient Sample database from 2003 to 2012. We included all patients who underwent isolated CABG surgery (n = 2,272,998; female n = 623,423 [27.4%]; male n = 1,649,575 [72.6%]). The annual rate of CABG surgeries decreased by 53.7% in men and 57.8% in women over the 10-year study period. Although internal mammary artery use in women was less frequent than in men in 2003 (77.4% vs 81.9%, p <0.001), a significant uptrend closed this gap by 2012 (86.2% vs 87.0%, ptrend 0.003). Overall, unadjusted in-hospital mortality was greater in women (3.2% vs 1.8%, p <0.001). Female gender remained an independent predictor of mortality after multivariate adjustment (odds ratio 1.40, 95% CI 1.36 to 1.43, p <0.001) across all age groups. However, in-hospital mortality decreased at a faster rate in women (3.8% to 2.7%, RR -29.1%, ptrend 0.002) than in men (2.2% to 1.6%, RR -25.7%, ptrend <0.001) from 2003 to 2012. In conclusion, CABG rates in the United States are decreasing over time, yet in-hospital mortality continues to improve. Women have worse in-hospital outcomes than men; however, the gender gap is slowly closing. PMID:27269585

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

    Injurious falls are the most prevalent in-hospital adverse event, and hospitalized patients are at a greater risk of falling than the general population. Patient engagement in hospital fall prevention could be a possible approach to reducing falls and fall-related injuries. To engage patients, bedside nursing staff must first understand the concept of patient centeredness and then incorporate patient centeredness in clinical practice. Clinicians should move from being experts to being enablers. To conceptualize the knowledge gaps identified, a conceptual model was developed to guide future research and quality improvement efforts in hospital settings. This model could be used as a guide to advance nursing leadership in hospital fall prevention via promoting patient engagement (e.g., developing patient-centered fall prevention interventions with patients' input).

    Sarcoidosis is a multisystem disease with an unpredictable and sometimes fatal course while the underlying pathomechanism is still unclear. Reasons of the increasing hospitalization rate and mortality in the United States remain in dispute but incriminated are a number of distinct comorbidities and risk factors as well as the application of more aggressive therapeutic agents. Studies reflecting the recent development in central Europe are lacking. Our aim was to investigate the recent mortality and hospitalization rates as well as the underlying comorbidities of hospitalized sarcoidosis patients in Switzerland. In this longitudinal, nested case-control study, a nation-wide database provided by the Swiss Federal Office for Statistics enclosing every hospital entry covering the years 2002–2012 (n = 15,627,573) was analyzed. There were 8,385 cases with a diagnosis of sarcoidosis representing 0.054% (8,385 / 15,627,573) of all hospitalizations in Switzerland. These cases were compared with age- and sex-matched controls without the diagnosis of sarcoidosis. Hospitalization and mortality rates in Switzerland remained stable over the observed time period. Comorbidity analysis revealed that sarcoidosis patients had significantly higher medication-related comorbidities compared to matched controls, probably due to systemic corticosteroids and immunosuppressive therapy. Sarcoidosis patients were also more frequently re-hospitalized (median annual hospitalization rate 0.28 [IQR 0.15-0.65] vs. 0.19 [IQR 0.13-0.36] per year; p < 0.001), had a longer hospital stay (6 [IQR 2-13] vs. 4 [IQR 1-8] days; p < 0.001), had more comorbidities (4 [IQR 2-7] vs. 2 [IQR 1-5]; p < 0.001), and had a significantly higher in-hospital mortality (2.6% [95% CI 2.3%-2.9%] vs. 1.8% [95% CI 1.5%-2.1%] (p < 0.001). A worse outcome was observed among sarcoidosis patients having co-occurrence of associated respiratory diseases. Moreover, age was an important risk factor for re-hospitalization. PMID

    Adult protein-calorie malnutrition, as reflected by decreased levels of serum albumin and transferrin, was studied in 21 hospitalized patients. This malnutrition state was a consequence of a catabolic response to stress and also use of standard parenteral fluid maintenance with 5% dextrose and water. Associated findings included a significant reduction in both total lymphocytes and cellular immunity, as measured by dinitrochlorobenzene and Candida skin testing. This state of visceral attrition, resembling kwashiorkor, occurs commonly in hospitalized patients, and may account for significant morbidity and mortality. Alternatives to the 5% dextrose and water in the nutritional support of the semistarved state may allow better preservation of visceral protein status and immune function. PMID:810018

    Esophagectomy, one of the most invasive of all gastrointestinal operations, is associated with a high frequency of postoperative complications and in-hospital mortality. The purpose of the present study was to determine whether exposure to the atomic bomb explosion at Hiroshima in 1945 might be a preoperative risk factor for in-hospital mortality after esophagectomy in esophageal cancer patients. We thus reviewed the outcomes of esophagectomy in 31 atomic bomb survivors with esophageal cancer and 96 controls (also with cancer but without atomic bomb exposure). We compared the incidences of postoperative complications and in-hospital mortality. Of the clinicopathological features studied, mean patient age was significantly higher in atomic bomb survivors than in controls. Of the postoperative complications noted, atomic bomb survivors experienced a longer mean period of endotracheal intubation and higher incidences of severe pulmonary complications, severe anastomotic leakage, and surgical site infection. The factors associated with in-hospital mortality were exposure to the atomic bomb explosion, pulmonary comorbidities, and electrocardiographic abnormalities. Multivariate analysis revealed that exposure to the atomic bomb explosion was an independent significant preoperative risk factor for in-hospital mortality. Exposure to the atomic bomb explosion is thus a preoperative risk factor for in-hospital death after esophagectomy to treat esophageal cancer. PMID:24224952

  13. Jewish mortality reconsidered.

    It is known that mortality of Jews is different from the mortality of the populations that surround them. However, the existence of commonalities in mortality of different Jewish communities across the world has not received scholarly attention. This paper aims to identify common features of the evolution of Jewish mortality among Jews living in Israel and the Diaspora. In the paper the mortality of Jews in Israel is systematically compared with the mortality of the populations of developed countries, and the findings from the earlier studies of mortality of Jews in selected Diaspora communities are re-examined. The outcome is a re-formulation and extension of the notion of the 'Jewish pattern of mortality'. The account of this pattern is based on the consistently low level of behaviourally induced mortality, the migration history of Jewish populations and the enduring influence of early-life conditions on mortality at older ages.

    Acute ischemic stroke is a time-critical emergency for which thrombolytic therapy is the only medical treatment. Many patients who would benefit from this treatment are deprived of it due to delays. Failure to call for help rapidly is the main obstacle, but even when the call is made in time, the prehospital evaluation, transportation, and emergency department (ED) diagnostics often take too long to treat the patient with thrombolysis. Interventions to reduce pre- and in-hospital delays have been described; although no single intervention is likely to make a major difference, a whole set of interventions needs to be implemented. The intersection of the pre- and in-hospital care is of special importance. With successful protocols and good communication between the emergency medical service and ED, delays can be significantly reduced. On the basis of our experience, 94% of patients can be treated within 60 min of arrival, based largely on using the prehospital time effectively. PMID:22994234

    Based on recent understanding of PM2.5 health-related problems from fossil-fueled power plants emission inventories collected in Taiwan, we have determined the loss of life expectancy (LLE) and the lifetime (75-year) risks for PM2.5 health-related mortalities as attributed to the operation of the world's largest coal-fired power plant; the Taichung Power Plant (TCP), with an installed nominal electrical capacity of 5780 MW in 2013. Five plausible scenarios (combinations of emission controls, fuel switch, and relocation) and two risk factors were considered. It is estimated that the lifetime (75-y) risk for all-cause mortality was 0.3%-0.6% for males and 0.2%-0.4% for females, and LLE at 84 days in 1997 for the 23 million residents of Taiwan. The risk has been reduced to one-fourth at 0.05%-0.10% for males and 0.03%-0.06% for females, and LLE at 15 days in 2007, which was mainly attributed to the installation of desulfurization and de-NOx equipment. Moreover, additional improvements can be expected if we can relocate the power plant to a downwind site on Taiwan, and convert the fuel source from coal to natural gas. The risk can be significantly reduced further to one-fiftieth at 0.001%-0.002% for males and 0.001% for females, and LLE at 0.3 days. Nonetheless, it is still an order higher than the commonly accepted elevated-cancer risk at 0.0001% (10-6), indicating that the PM2.5 health-related risk for operating such a world-class power plant is not negligible. In addition, this study finds that a better-chosen site (involving moving the plant to the leeward side of Taiwan) can reduce the risk significantly as opposed to solely transitioning the fuel source to natural gas. Note that the fuel cost of using natural gas (0.11 USD/kWh in 2013) in Taiwan is about twice the price of using coal fuel (0.05 USD/kWh in 2013).

    Sepsis is an important cause of patient morbidity and mortality worldwide. Although the associated mortality seems to be decreasing, approximately 20 % of patients with organ dysfunction die in hospital. Since 1991 diagnostic criteria for sepsis focused on the systemic inflammatory response syndrome (SIRS). However, the utility of such criteria has been questioned, and alternative criteria have recently been proposed. It is likely that administration of early appropriate antibiotics and resolution of shock reduce sepsis-associated mortality. Accordingly, strategies need to be developed to improve the early recognition of, and response to patients with sepsis. Such system approaches may include improved acquisition and documentation of vital signs, enhanced recognition of shock, and integration of laboratory and microbiological results using clinical informatics. Hospitals should have guidelines for escalating care of septic patients, antibiotics stewardship programs, and systems to audit morbidity and mortality associated with sepsis. PMID:27193917

    The expectations of patient are one of the determining factors of healthcare service. The purpose of this study is to measure the Patients' Expectations, based on Patient's Rights. This study was done with Likert-Survey in Trabzon population. The analyses showed that the level of the expectations of the patient was high on the factor of receiving information and at an acceptable level on the other factors. Statistical meaningfulness was determined between age, sex, education, health insurance, and the income of the family and the expectations of the patients (p<0.05). According to this study, the current legal regulations have higher standards than the expectations of the patients. The reason that the satisfaction of the patients high level is interpreted due to the fact that the level of the expectation is low. It is suggested that the educational and public awareness studies on the patients' rights must be done in order to increase the expectations of the patients. PMID:17028043

    Acute kidney injury (AKI) is a common reason for hospital admission and complication of many inpatient procedures. The temporal incidence of AKI and the association of AKI admissions with in-hospital mortality are a growing problem in the world today. In this review, we discuss the epidemiology of AKI and its association with in-hospital mortality in the United States. AKI has been growing at a rate of 14% per year since 2001. However, the in-hospital mortality associated with AKI has been on the decline starting with 21.9% in 2001 to 9.1 in 2011, even though the number of AKI-related in-hospital deaths increased almost twofold from 147,943 to 285,768 deaths. We discuss the importance of the 71% reduction in AKI-related mortality among hospitalized patients in the United States and draw on the discussion of whether or not this is a phenomenon of hospital billing (coding) or improvements to the management of AKI.

    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.

    The paper explains the reasons according to which the newly-planned hospitals must adopt the concept of advanced flexibility (structural, technological, organizational, diagnostic and therapeutic), in order to avoid the risk of being already obsolete at the moment of their opening, and this due to the fact that too much time elapses in this Country between the moment of planning a new hospital and the moment of the start of its activity. Flexibility is needed at different levels: at low or medium levels for what concerns administrative spaces and also patient rooms (except, in this latter case, when differential intensity of care is adopted); at advanced levelfor what concerns diagnostic and therapeutic areas, which must be rapidly adaptable to new solutions offered by advances in technology and organization. From a different standpoint, flexibility applies also to the fact that hospital must increasingly become a node of a large net including territorial health services: the latter devoted to take care of chronicity, while hospitals should concentrate on acute pathology. Of course the territory surrounding the hospital, through its outpatient service and consultories, is in charge also for first level diagnosy and therapy, leaving the hospital to more sophisticated activities.

    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.

    Objective In chronically ill children who are hospitalized, many mood changes occur. For example, in children with cancer or renal failure, prolonged hospitalization and chemotherapy can lead to depression. With the improved survival of childhood malignancies, the effect of treatment on child’s psychosocial well-being becomes increasingly relevant. In this study, we examined the prevalence of depression in hospitalized children with chronic and acute conditions in Dr Sheikh Pediatrics Hospital in Mashhad. Materials & Methods After receiving the approval from the Ethics Committee of Mashhad University of Medical Sciences, we did this cross-sectional descriptive study, from April to June 2012 in Dr Sheikh Pediatric Hospital in Mashhad. Ninety children, between 8 to 16 years, were screened for depression. The sampling method was census. Children with a history of depressive or other mental disorders were excluded. Three groups of children (children with chronic renal disease, malignancy, and acute disease) were evaluated for depression using standard Children Depression Inventory Questionnaire (CDI). Two specifically trained nurses filled out the questionnaires at patients’ bedside under the supervision of a psychiatrist. Depression scores were then analyzed by SPSS software. Results Of 90 children, 43(47.7%) were male and 47(52.2%) were female. The Children’s mean age was 11±2.3 years, and the mean length of hospitalization was 8±5.3 days. Depression was detected in various degrees in 63% of patients (N=57), and 36.6% of children (N=32) had no symptoms of depression. Severe depression was not seen in any of the patients with acute illness. More than half of patients with cancer and chronic kidney disease had moderate to severe depression. There was a significant statistical relationship between the duration of illness and severity of depression. There was also a significant correlation between severity of depression and frequency of hospitalization. Children

    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.

    Abstract Anemia is a disputable factor for long-term mortality in hip fracture population in previous studies. Previous studies indicated that the level of hemoglobin (Hb) might fluctuate due to various factors, such as comorbidities and in-hospital interventions, and the changing level of Hb, may lead to discordance diagnosis of anemia and thus to the conflicting conclusions on prognostic value of anemia. So in this study, we aim to compare factors affecting the diagnosis of anemia at different time-points, admission, postoperation, and discharge, and to determine which the time point is most suitable for mortality prediction. This prospective cohort study included 1330 hip fracture patients from 1 January 2000 to 18 November 2012. Hb levels at 3 different time points, such as admission, postoperation, and discharge, were collected and used to stratify the cohort into anemia and nonanemia groups. Candidate factors including commodities, perioperative factors, blood transfusion, and other in-hospital interventions were collected before discharge. Logistic regression analyses were performed to detect risk factors for anemia for the 3 time points separately. Kaplan–Meier and multivariate Cox regression analyses were used to evaluate the association between anemia and 2-year mortality. Factors affecting the diagnosis of anemia were different for the 3 time points. Age, female sex, American Society of Anesthesiologists score (ASA), and intertrochanteric fracture were associated with admission anemia, while surgical procedure, surgical duration, blood transfusion, blood loss during the operation, and drainage volume were major risk factors for postoperation anemia. Cox proportional-hazards regression analysis suggested that the risk of all-cause mortality was higher in the anemia group on admission (1.680, 95%CI: 1.201–2.350, P < 0.01), but not postoperation or on discharge, after adjustment for confounding factors. Our study showed that risk factors for anemia

    2012-01-01

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

    Opioid use is associated with unintentional and intentional overdose and is one of the leading causes of emergency room visits and accidental deaths. However, the association between opioid abuse/dependence and outcomes in hospitalized patients has not been well studied. Congestive heart failure (HF) is the fourth most common cause of hospitalization in the United States. The purpose of this study was to examine the effect of opioid abuse/dependence on outcomes in patients hospitalized with HF. We queried the 2002-2010 Nationwide Inpatient Sample databases to identify all patients aged 18 years and older admitted with the primary diagnosis of HF. Multivariate logistic regression analysis was used to compare the frequency of hospital-acquired conditions (HACs) and in-hospital mortality between patients with and without a history of opioid abuse/dependence. Of 9,993,240 patients with HF, 29,014 had a history of opioid abuse or dependence. Opioid abusers/dependents were likely to be younger men of poor socioeconomic background with self pay or Medicaid as their primary payer. They had a lower prevalence of dyslipidemia, diabetes mellitus, coronary artery disease, prior myocardial infarction, and peripheral vascular disease (P < 0.001 for all). They were more likely to be smokers and have chronic pulmonary disease, depression, liver disease, and obesity (P < 0.001 for all). Patients with a history of opioid abuse/dependence had lower incidence of HACs (14.8% vs. 16.5%, adjusted odds ratio: 0.71, P < 0.001) and lower in-hospital mortality (1.3% vs. 3.6%, adjusted odds ratio: 0.64, P < 0.001) as compared with patients without prior opioid abuse/dependence. In conclusion, among adult patients aged 18 years and older hospitalized with HF, opioid abuse/dependence was associated with lower frequency of HACs and lower in-hospital mortality. PMID:25611362

    Background: The use of multidisciplinary in-hospital teams limits adverse events (AE), improves outcomes, and adds to patient and employee satisfaction. Methods: Acting like “well-oiled machines,” multidisciplinary in-hospital teams include “staff” from different levels of the treatment pyramid (e.g. staff including nurses’ aids, surgical technicians, nurses, anesthesiologists, attending physicians, and others). Their enhanced teamwork counters the “silo effect” by enhancing communication between the different levels of healthcare workers and thus reduces AE (e.g. morbidity/mortality) while improving patient and healthcare worker satisfaction. Results: Multiple articles across diverse disciplines incorporate a variety of concepts of “teamwork” for staff covering emergency rooms (ERs), hospital wards, intensive care units (ICUs), and most critically, operating rooms (ORs). Cohesive teamwork improved communication between different levels of healthcare workers, and limited adverse events, improved outcomes, decreased the length of stay (LOS), and yielded greater patient “staff” satisfaction. Conclusion: Within hospitals, delivering the best medical/surgical care is a “team sport.” The goals include: Maximizing patient safety (e.g. limiting AE) and satisfaction, decreasing the LOS, and increasing the quality of outcomes. Added benefits include optimizing healthcare workers’ performance, reducing hospital costs/complications, and increasing job satisfaction. This review should remind hospital administrators of the critical need to keep multidisciplinary teams together, so that they can continue to operate their “well-oiled machines” enhancing the quality/safety of patient care, while enabling “staff” to optimize their performance and enhance their job satisfaction.

    The airline industry may be an occupational setting with specific health risks. Two environmental agents to which flight crews are known to be exposed are cosmic radiation and magnetic fields generated by the aircraft's electrical system. Other factors to be considered are circadian disruption and conditions specific to air travel, such as noise, vibration, mild hypoxia, reduced atmospheric pressure, low humidity, and air quality. This study investigated mortality among US commercial pilots and navigators, using proportional mortality ratios for cancer and noncancer end points. Proportional cancer mortality ratios and mortality odds ratios were also calculated for comparison to the proportional mortality ratios for cancer causes of death. Results indicated that US pilots and navigators have experienced significantly increased mortality due to cancer of the kidney and renal pelvis, motor neuron disease, and external causes. In addition, increased mortality due to prostate cancer, brain cancer, colon cancer, and cancer of the lip, buccal cavity, and pharynx was suggested. Mortality was significantly decreased for 11 causes. To determine if these health outcomes are related to occupational exposures, it will be necessary to quantify each exposure separately, to study the potential synergy of effects, and to couple this information with disease data on an individual basis.

    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.

    Objectives To determine whether late mortality after sepsis is driven predominantly by pre-existing comorbid disease or is the result of sepsis itself. Deign Observational cohort study. Setting US Health and Retirement Study. Participants 960 patients aged ≥65 (1998-2010) with fee-for-service Medicare coverage who were admitted to hospital with sepsis. Patients were matched to 777 adults not currently in hospital, 788 patients admitted with non-sepsis infection, and 504 patients admitted with acute sterile inflammatory conditions. Main outcome measures Late (31 days to two years) mortality and odds of death at various intervals. Results Sepsis was associated with a 22.1% (95% confidence interval 17.5% to 26.7%) absolute increase in late mortality relative to adults not in hospital, a 10.4% (5.4% to 15.4%) absolute increase relative to patients admitted with non-sepsis infection, and a 16.2% (10.2% to 22.2%) absolute increase relative to patients admitted with sterile inflammatory conditions (P<0.001 for each comparison). Mortality remained higher for at least two years relative to adults not in hospital. Conclusions More than one in five patients who survives sepsis has a late death not explained by health status before sepsis. PMID:27189000

    Hospitals have been advised to respond to environmental pressures by changing from a product to a market orientation. Such changes are difficult to accomplish because of the entrenched behaviors and attitudes of hospitals employees. This article proposes organizational cultures as the avenue to a market orientation. It describes the role of hospital culture as an antecedent to market orientation. It also suggests ways to develop and maintain a market-oriented culture in hospitals. PMID:10161845

    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.

    There is a high rate of mortality in elderly patients who sustain a fracture of the hip. We aimed to determine the rate of preventable mortality and errors during the management of these patients. A 12 month prospective study was performed on patients aged > 65 years who had sustained a fracture of the hip. This was conducted at a Level 1 Trauma Centre with no orthogeriatric service. A multidisciplinary review of the medical records by four specialists was performed to analyse errors of management and elements of preventable mortality. During 2011, there were 437 patients aged > 65 years admitted with a fracture of the hip (85 years (66 to 99)) and 20 died while in hospital (86.3 years (67 to 96)). A total of 152 errors were identified in the 80 individual reviews of the 20 deaths. A total of 99 errors (65%) were thought to have at least a moderate effect on death; 45 reviews considering death (57%) were thought to have potentially been preventable. Agreement between the panel of reviewers on the preventability of death was fair. A larger-scale assessment of preventable mortality in elderly patients who sustain a fracture of the hip is required. Multidisciplinary review panels could be considered as part of the quality assurance process in the management of these patients. Cite this article: Bone Joint J 2014;96-B:1178–84. PMID:25183587

    2016-01-01

    The incidence of gram-negative multidrug-resistant (MDR) bacterial pathogens is increasing in hospitals and particularly in the intensive care unit (ICU) setting. The clinical consequences of infections caused by MDR pathogens remain controversial. The purpose of this review is to summarize the available data concerning the impact of these infections on mortality in ICU patients. Twenty-four studies, conducted exclusively in ICU patients, were identified through PubMed search over the years 2000-2015. Bloodstream infection was the only infection examined in eight studies, respiratory infections in four and variable infections in others. Comparative data on the appropriateness of empirical antibiotic treatment were provided by only seven studies. In ten studies the presence of antimicrobial resistance was not associated with increased mortality; on the contrary, in other studies a significant impact of antibiotic resistance on mortality was found, though, sometimes, mediated by inappropriate antimicrobial treatment. Therefore, a direct association between infections due to gram-negative MDR bacteria and mortality in ICU patients cannot be confirmed. Sample size, presence of multiple confounders and other methodological issues may influence the results. These data support the need for further studies to elucidate the real impact of infections caused by resistant bacteria in ICU patients. PMID:27152254

    There are theoretical reasons to expect that high risk of mortality or morbidity during young adulthood decreases investment in human capital. However, investigation of this hypothesis is complicated by a variety of empirical challenges, including difficulties in inferring causation due to omitted variables and reverse causation. For example, to compare two groups with substantially different mortality rates, one typically has to use samples from different countries or periods, making it difficult to control for other relevant variables. Reverse causation is important because human capital investment can affect mortality and morbidity. To counter these problems, we collected data on human capital investments, fertility decisions, and other economic choices of people at risk for Huntington's disease. Huntington's disease is a fatal genetic disorder that introduces a large and exogenous risk of early mortality and morbidity. We find a strong negative relation between mortality and morbidity risks and human capital investment. PMID:22308067

    To estimate the excess mortality due to alcohol in England and Wales death rates specific to alcohol consumption that had been derived from five longitudinal studies were applied to the current population divided into categories of alcohol consumption. Because of the J shaped relation between alcohol consumption and death the excess mortality used as a baseline was an alcohol consumption of 1-10 units/week and an adjustment was made for the slight excess mortality of abstainers. The number of excess deaths was obtained by subtracting the number of deaths expected if all the population had the consumption of the lowest risk group; correction for the total observed mortality in the population was made. This resulted in an estimate of 28,000 deaths each year in England and Wales as the excess mortality among people aged 15-74 associated with alcohol consumption. PMID:3140936

    Family planning can improve infant survival. Specifically, use of family planning methods can minimize family size, increase birth spacing, and reduce the likelihood of pregnancy for teenagers and women aged 40 or older. Immunizations and oral rehydration are responsible for the falling infant mortality rats since 1977 in developing countries, especially among 1-12 month old infants. Yet, neonatal mortality in developing countries had not changed. WHO intends to step up efforts to improve newborn survival. Accurate data are needed, however. Even in developed countries which keep good statistics, infant mortality bias exists. For example, in Japan, some infant deaths are called fetal deaths. In developing countries, much of the data come from hospitals, yet most birth do not occur in hospitals. Even in surveys, bias exists, such as problems with recall. Many researchers use traditional birth attendants (TBAs) to follow up on all births in an area which may eliminate some biases. Such a prospective and longitudinal study in Trairi county in northeastern Brazil shows the infant mortality rate to be less than half of the official rate (65 vs. 142). The major causes of infant death in developed countries, which tends to occur in the neonatal period, are low birth weight, prematurity, birth complications, and congenital defects; developing countries; they are vaccine preventable infectious diseases, diarrhea and dehydration, and respiratory illnesses, all complicated by malnutrition. To make further strides in reducing infant mortality, public health workers must concentrate on the neonatal period. Training TBAs in sterile techniques, appropriate technology, resuscitation of infants, and identification of potential problems is a positive step. Yet, unpredictable conditions (e.g., AIDS) exist and/or will arise which erode improvements. For example, in Nicaragua, within 1 year after the new government introduced health budget cuts which resulted in the poor paying for

    Cocaine use is associated with higher mortality in small retrospective studies of brain-injured patients. We aimed to explore in-hospital outcomes in a large population based study of aneurysmal subarachnoid hemorrhage (aSAH) with cocaine use. aSAH patients were identified from the 2007-2010 USA Nationwide Inpatient Sample using International Classification of Disease, Ninth Revision codes. Demographics, comorbidities and surgical procedures were compared between cocaine users and non-users. The primary outcomes were in-hospital mortality and home discharge/self-care. Secondary outcomes were vasospasm treated with angioplasty, hydrocephalus, gastrostomy and tracheostomy. There were 103,876 patients with aSAH. The cocaine group were younger (45.8 ± 9.8 versus 58.4 ± 15.8, p<0.001), predominantly male (53.3% versus 38.5%, p<0.001) and had a higher proportion of black patients (36.9% versus 11.5%, p<0.001). The incidence of seizures was higher among cocaine users (16.2% versus 11.1%, p<0.001). Endovascular coiling of intracranial aneurysms (24% versus 18.5%, p<0.001) was more frequent in cocaine users. The univariate analysis showed higher rates of in-hospital mortality and vasospasm treated with angioplasty, but lower home discharge in the cocaine group. In the multivariate analysis, the cocaine cohort had higher in-hospital mortality (odds ratio [OR] 1.43, 95% confidence interval [CI] 1.27-1.61, p<0.001) and lower home discharge rates (OR 0.79, 95% CI 0.69-0.87, p<0.001) after adjusting for confounders. Rates of vasospasm treated with angioplasty however were similar between the two groups. Cocaine use was found to be independently associated with poor outcomes, particularly higher mortality and lower home discharge rates. Cocaine use however, was not associated with vasospasm that required treatment with angioplasty. Prospective confirmation is warranted. PMID:24998859

    Background On-going climate change is predicted to result in a growing number of extreme weather events—such as heat waves—throughout Europe. The effect of high temperatures and heat waves are already having an important impact on public health in terms of increased mortality, but studies from an Estonian setting are almost entirely missing. We investigated mortality in relation to high summer temperatures and the time course of mortality in a coastal and inland region of Estonia. Methods We collected daily mortality data and daily maximum temperature for a coastal and an inland region of Estonia. We applied a distributed lag non-linear model to investigate heat related mortality and the time course of mortality in Estonia. Results We found an immediate increase in mortality associated with temperatures exceeding the 75th percentile of summer maximum temperatures, corresponding to approximately 23°C. This increase lasted for a couple of days in both regions. The total effect of elevated temperatures was not lessened by significant mortality displacement. Discussion We observed significantly increased mortality in Estonia, both on a country level as well as for a coastal region and an inland region with a more continental climate. Heat related mortality was higher in the inland region as compared to the coastal region, however, no statistically significant differences were observed. The lower risks in coastal areas could be due to lower maximum temperatures and cooling effects of the sea, but also better socioeconomic condition. Our results suggest that region specific estimates of the impacts of temperature extremes on mortality are needed. PMID:27167851

    1995-01-01

    STUDY OBJECTIVE--The study aimed to analyse avoidable mortality in Lithuania as an index of the quality of health care and to assess trends in avoidable mortality from 1970-90. SETTING AND PARTICIPANTS--All deaths of Lithuanian residents aged between 0 and 64 years between 1970 and 1990 were analysed. MEASUREMENTS AND MAIN RESULTS--Twenty seven per cent of all deaths in this age group were avoidable. Avoidable deaths were grouped into preventable and treatable ones. Treatable causes of death accounted for 54%, and preventable, 46% of avoidable mortality. Time trends showed that general mortality and mortality from avoidable causes of death in this age group were almost stable between 1970 and 1990. Mortality from treatable causes of death fell, while deaths from preventable causes increased. The results in the preventable group were greatly affected by deaths from malignant neoplasms of trachea, bronchus, and lungs. Differences were noted between the sexes in total mortality as well as in avoidable mortality. CONCLUSIONS--Avoidable causes of death are relatively common and, consequently, they are of practical importance for public health and studies of the health care quality in Lithuania. Reorganisation of health care is to be carried out and considerable emphasis will be placed on health education, promotion, and prevention, as primary prevention measures have not been effective thus far.

    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

    Holistic medicine is the global trend in medical care. It involves not only the highest possible standard of diagnosis and treatment, but also designing the whole experience of being ill and that of hospitalization. In such a frame, planning and designing for children has to be considered in such a way that a child will be helped to withstand the effects of illness, the separation from home and family and the entrance into an unusual, unfamiliar and strange world. Although the wellbeing and happiness of children in hospital is the concern of the nursing staff and of the parents, many other factors have to be satisfied also. A young ill child who has to be treated in hospital has to adjust to a number of environmental and treatment conditions which may be upsetting and may have far-reaching effects. Because of all these, much effort has been made, over the last fifty years, to develop planning and design aspects, which will make a child's life in hospital less unnatural. Furthermore, it will reduce the unavoidable and inevitable discomfort, disease, pain and misery experienced by children. These aspects include avoidance of admission of children into hospital whenever possible, operations on a daily basis, unrestricted visits, encouraging of parents to visit or to stay with their children, the provision of suitable playing facilities, materials, equipment etc. This paper will seek to explore and develop: a change in philosophy in child care, its influence on the various types of facilities, the importance of the family, the psychological needs as design factors such as security, social contacts, personal space, movement, comfort, independence, outdoor spaces and others. Factors relating to design parameters and standards will also be explored. The meaning and importance of scale is highlighted since it is felt that children are not miniature adults, but individuals with their own particular capacities. PMID:11214456

    Radio frequency identification (RFID) technology has recently begun to receive increased interest from practitioners and academicians. This interest is driven by mandates from major retailers such as Wal-Mart, Target and Metro Group, and the United States Department of Defense, in order to increase the efficiency and visibility of material and information flows in the supply chain. However, supply chain managers do not have a monopoly on the deployment of RFID. In this article, the authors discuss the potential benefits, the areas of applications, the implementation challenges, and the corresponding strategies of RFID in hospital environments.

    Family-centered care is an approach to the planning, delivery, and evaluation of healthcare based on partnership between parents and professionals. Family-centered rounds (FCRs) are a practical application in hospital settings. They are multidisciplinary rounds with active participation of the parents in the decision-making process. FCRs appear to have a positive impact on parents' satisfaction, information provision, and comprehension of care plans. Three concerns have been underlined: time management, confidentiality, and teaching students. FCR implementation is a process that requires in-depth thinking on the philosophy of care, staff information and training, and a specific organizational change. PMID:26774896

    1991-12-01

    The causes (medical, reproductive factors, health care delivery system, and socioeconomic factors) of maternal mortality in India and strategies for reducing maternal mortality are presented. Maternal mortality rates (MMR) are very high in Asia and Africa compared with Northern Europe's 4/100,000 live births. An Indian hospital study found the MMR to be 4.21/1000 live births. 50-98% of maternal deaths are caused by direct obstetric causes (hemorrhage, infection, and hypertensive disorders, ruptured uterus, hepatitis, and anemia). 50% of maternal deaths due to sepsis are related to illegal induced abortion. MMR in India has not declined significantly in the past 15 years. Age, primi and grande multiparity, unplanned pregnancy, and related illegal abortion are the reproductive causes. In 1985 WHO reported that 63-80% of maternal deaths due to direct obstetric causes and 88-98% of all maternal deaths could probably have been prevented with proper handling. In India, coordination between levels in the delivery system and fragmentation of care account for the poor quality of maternal health care. Mass illiteracy is another cause. Effective strategies for reducing the MMR are 1) to place a high priority on maternal and child health (MCH) services and integrate vertical programs (e.g., family planning) related to MCH; 2) to give attention to care during labor and delivery, which is the most critical period for complications; 3) to provide community-based delivery huts which can provide a clean and safe delivery place close to home, and maternity waiting rooms in hospitals for high risk mothers; 4) to improve the quality of MCH care at the rural community level (proper history taking, palpation, blood pressure and fetal heart screening, risk factor screening, and referral); 5) to improve quality of care at the primary health care level (emergency care and proper referral); 6) to include in the postpartum program MCH and family planning services; 7) to examine the

    Objective: To evaluate the mortality rate in patients with narcolepsy. Design: Data were derived from a large database representative of the US population, which contains anonymized patient-linked longitudinal claims for 173 million individuals. Setting: Symphony Health Solutions (SHS) Source Lx, an anonymized longitudinal patient dataset. Patients/Participants: All records of patients registered in the SHS database between 2008 and 2010. Interventions: None Measurements and Results: Identification of patients with narcolepsy was based on ≥ 1 medical claim with the diagnosis of narcolepsy (ICD-9 347.xx) from 2002 to 2012. Dates of death were acquired from the Social Security Administration via a third party; the third party information was encrypted in the same manner as the claims data such that anonymity is ensured prior to receipt by SHS. Annual all-cause mortality rates for 2008, 2009, and 2010 were calculated retrospectively for patients with narcolepsy and patients without narcolepsy in the database, and standardized mortality ratios (SMR) were calculated. Mortality rates were also compared with the general US population (Centers for Disease Control data). SMRs of the narcolepsy population were consistent over the 3-year period and showed an approximate 1.5-fold excess mortality relative to those without narcolepsy. The narcolepsy population had consistently higher mortality rates relative to those without narcolepsy across all age groups, stratified by age decile, from 25-34 years to 75+ years of age. The SMR for females with narcolepsy was lower than for males with narcolepsy. Conclusions: Narcolepsy was associated with approximately 1.5-fold excess mortality relative to those without narcolepsy. While the cause of this increased mortality is unknown, these findings warrant further investigation. Citation: Ohayon MM; Black J; Lai C; Eller M; Guinta D; Bhattacharyya A.

    Data regarding prognostic factors for patients with septic pulmonary embolism (SPE) are lacking. The purpose of the present study was to investigate the clinical features of SPE and to ascertain the risk factors for mortality in patients with this condition. Patients with SPE, whose data were retrospectively collected from a tertiary referral center in Korea, were categorized by the presence or absence of in-hospital death into two groups: death and survival groups. The two groups were compared for clinical and radiologic parameters. SPE was community-acquired in most patients (78%). The most common focus of primary infection was that of bone, joint, or soft tissue (33%), followed by liver abscess (17%). The in-hospital mortality was 12%. Multivariate analysis showed that tachypnea (odds ratio [OR] 4.73, 95% confidence interval [CI] 1.09-20.53, p = 0.038) and segmental or lobar consolidation on computed tomography (CT) scan (OR 10.79, 95% CI 2.51-46.43, p = 0.001) were independent predictors of in-hospital death in SPE patients. Taken together, the primary infectious foci of SPE in Korea are different from those reported in Western countries. Tachypnea and segmental or lobar consolidation on CT scan may be independent risk factors for in-hospital death in these patients. PMID:27346380

    Objective The aim of this study was to evaluate the effectiveness of clinical criteria for the diagnosis of hyposalivation in hospitalized patients. Material and Methods A clinical study was carried out on 145 subjects (48 males; 97 females; aged 20 to 90 years). Each subject was clinically examined, in the morning and in the afternoon, along 1 day. A focused anamnesis allowed identifying symptoms of hyposalivation, like xerostomia complaints (considered as a reference symptom), chewing difficulty, dysphagia and increased frequency of liquid intake. Afterwards, dryness of the mucosa of the cheecks and floor of the mouth, as well as salivary secretion during parotid gland stimulation were assessed during oral examination. Results Results obtained with Chi-square tests showed that 71 patients (48.9%) presented xerostomia complaints, with a significant correlation with all hyposalivation symptoms (p<0.05). Furthermore, xerostomia was also significantly correlated with all data obtained during oral examination in both periods of evaluation (p<0.05). Conclusion Clinical diagnosis of hyposalivation in hospitalized patients is feasible and can provide an immediate and appropriate therapy avoiding further problems and improving their quality of life.

  14. Mortality in Asia.

    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

    The purpose of this article is to describe factors contributing to potentially preventable mortality in academic medical centers and the organizational characteristics associated with success in reducing mortality. Sixteen U.S. academic medical centers that wished to improve risk-adjusted inpatient mortality rates requested a consultation that included interviews with physicians, nurses, and hospital leaders; review of medical records; and evaluation of systems and processes of care. The assessments took place on-site; they identified key factors contributing to preventable mortality, and each hospital received specific recommendations. Changes in observed mortality and in the ratio of observed to expected mortality were measured from 2002 to final follow-up in 2007. Evaluations determined each hospital's success factors and key barriers to improvement. The key factors contributing to preventable mortality were delays in responding to deteriorating patients, suboptimal critical care, hospital-acquired infections, postoperative complications, medical errors, and community issues such as the availability of hospice care. Of the 16 hospitals, 12 were able to reduce their mortality index. The five hospitals that had the greatest improvement in mortality were the only hospitals with a broad level of engagement among hospital and physician leaders, including the department chairs. In the hospitals whose performance did not improve, the department chairs were not engaged in the process. The academic medical centers that focused on mortality reduction and had engagement of physicians, especially department chairs, were able to achieve meaningful reductions in hospital mortality. The necessary ingredients for achieving meaningful improvement in clinical outcomes included good data, a sound method for change, and physician leadership. PMID:19940569

    We characterized the dynamics of mortality factors affecting immature developmental stages of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Multiple decrement life tables for egg and early larval stages of S. frugiperda in maize (Zea mays L.) fields were developed with and without augmentative releases of Telenomus remus Nixon (Hymenoptera: Platygastridae) from 2009 to 2011. Total egg mortality ranged from 73 to 81% and the greatest egg mortality was due to inviability, dislodgement, and predation. Parasitoids did not cause significant mortality in egg or early larval stages and the releases of T. remus did not increase egg mortality. Greater than 95% of early larvae died from predation, drowning, and dislodgment by rainfall. Total mortality due to these factors was largely irreplaceable. Results indicate that a greater effect in reducing generational survival may be achieved by adding mortality to the early larval stage of S. frugiperda. PMID:26098422

    We describe the changes that have been presented in the tendencies of mortality and hospital discharges by tuberculosis (TB) between 1985-1999, period before and during the implementation of the Health Sector Reform (HSR) in Colombia. For it, we carried out an exploratory descriptive study with analysis of time series of hospital discharges and mortality rates of TB in Colombia. It was found that although starting from 1991 the Series approach stabilized, their tendencies showed a significant descent diminishing both in 30% between 1985 and 1990. The steady trend registered from 1991 to 1999, could be explained by deterioration of the primary care during this period, also due to other complex social processes occurred in Colombia during this decade, which barred the continuing the descent trend in hospital discharges and mortality due to TB previously registered. Due to the study design limitations we cannot establish causal relationships between these trends and the health sector reform in the country; we recommend the improvement the health sector performance about public health problems such as TB in order to avoid unnecessary hospitalizations and deaths due to causes responsive to health sector interventions.

    Objective This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). Background Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. Methods Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group) and those with left-dominant anatomy (LD group). Results The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003). In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001). Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06–2.89; P = 0.030). Conclusion Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Cancer is one of the most common risk factors for acute pulmonary embolism (PE), but only few studies report on the short-term outcome of patients with PE and a history of cancer. The aim of the study was to assess whether a cancer diagnosis affects the clinical presentation and short-term outcome in patients hospitalized for PE who were included in the Italian Pulmonary Embolism Registry. All-cause and PE-related in-hospital deaths were also analyzed. Out of 1702 patients, 451 (26.5 %) of patients had a diagnosis of cancer: cancer was known at presentation in 365, or diagnosed during the hospital stay for PE in 86 (19 % of cancer patients). Patients with and without cancer were similar concerning clinical status at presentation. Patients with cancer less commonly received thrombolytic therapy, and more often had an inferior vena cava filter inserted. Major or intracranial bleeding was not different between groups. In-hospital all-cause death occurred in 8.4 and 5.9 % of patients with and without cancer, respectively. At multivariate analysis, cancer (OR 2.24, 95 % CI 1.27-3.98; P = 0.006) was an independent predictor of in-hospital death. Clinical instability, PE recurrence, age ≥75 years, recent bed rest ≥3 days, but not cancer, were independent predictors of in-hospital death due to PE. Cancer seems a weaker predictor of all-cause in-hospital death compared to other factors; the mere presence of cancer, without other risk factors, leads to a probability of early death of 2 %. In patients with acute PE, cancer increases the probability of in-hospital all-cause death, but does not seem to affect the clinical presentation or the risk of in-hospital PE-related death.

    AIM To study the success and outcome of trabeculectomy in Hospital Melaka. METHODS Medical records of all patients who underwent trabeculectomy between January 1, 2007 and October 31, 2010 whom were followed up for at least 6 months postoperatively in Hospital Melaka were retrospectively reviewed. RESULTS A total number of 117 eyes of 91 patients with the age range between 12 to 84 years underwent primary trabeculectomy (n=20, 17.1%), combine trabeculectomy with cataract surgery (n=90, 76.9%), repeat trabeculectomy (n=5, 4.3%), and combine repeat trabeculectomy with cataract surgery (n=2, 1.7%). The disease spectrum includes primary open-angle glaucoma (POAG) (54 patients, 59.3%), priamry angle-closure glaucoma (PACG) (14 patients, 15.4%), secondary glaucomas (19 patients, 20.9%) and juvenile glaucomas (4 patients, 4.4%). Preoperative mean intraocular pressure (IOP) was (24.69±8.67)mmHg as compared to postoperative mean IOP of (15.81±6.66)mmHg, (15.07±4.72)mmHg and (15.68 ±3.65)mmHg at 6-month, 12-month and 24-month respectively. Eighty-two point one percent of eyes (n=96) achieved complete success (CS), 12.8% (n=15) with qualified success (QS) and only 5.1% (n=6) failed at 6 month with two of them warrant other filtering surgery. At twelve months, trabeculectomy with CS was 71.6% (n=63), QS in 22.7% (n=20) and failure in 5.7% (n=5). Sixty-seven point five percent (n=27) attained CS, 20.0% (n=8) with QS while 12.5% (n=5) failed at 24 month postoperative. CONCLUSION As the understanding of the lower the IOP, the better the patients retaining the visual function, trabeculectomy is significantly a choice of treatment in uncontrolled glaucoma. This study concluded that trabeculectomy performed in Hospital Melaka has produced significant success as compared to other studies. PMID:22773993

  2. Biodemographic analysis of male honey bee mortality.

    Biodemographic studies of insects have significantly enhanced our understanding of the biology of aging. Eusocial insects have evolved to form different groups of colony members that are specialized for particular tasks and highly dependent on each other. These different groups (castes and sexes) also differ strongly in their life expectancy but relatively little is known about their mortality dynamics. In this study we present data on the age-specific flight activity and mortality of male honey bees from two different genetic lines that are exclusively dedicated to reproduction. We show that males initiating flight at a young age experience more flight events during their lifetime. No (negative) relation between the age at flight initiation and lifespan exists, as might be predicted on the basis of the antagonistic pleiotropy theory of aging. Furthermore, we fit our data to different aging models and conclude that overall a slight deceleration of the age-dependent mortality increase at advanced ages occurs. However, mortality risk increases according to the Gompertz-Makeham model when only days with flight activity (active days) are taken into account. Our interpretation of the latter is that two mortality components act on honey bee males during flight: increasing, age-dependent deaths (possibly from wear-and-tear), and age-independent deaths (possibly due to predation). The overall mortality curve is caused by the interaction of the distribution of age at foraging initiation and the mortality function during the active (flight) lifespan. PMID:15659209

    Little attention has yet been payed on establishing modern and competitive organizational structures in German hospitals. In this paper, we attempt to apply elements of lean management to the work of physicians working in an inpatient setting. Traditional ways of communication and their disadvantages are discussed. These include loss of motivation, bureaucratic structures and a lack of interdisciplinary cooperation. Using Maslow's theory of motivation, possible improvements are discussed, such as the reduction of restrictive job characteristics, an increase of physicians' spheres of competence and the use of their innovative potentials. These suggestions are explained using practical examples. The aim of the study is to contribute to quality management in hospitals by increasing personal responsibilities according to lean management. PMID:10985072

    Background: Instead of waiting for challenges to confront hospital management, doctors and managers should act in advance to optimize and sustain value-based health. This work highlights the importance of scenario planning in hospitals, proposes an elaborated definition of the stakeholders of a hospital and defines the influence factors to which hospitals are exposed to. Methodology: Based on literature analysis as well as on personal interviews with stakeholders we propose an elaborated definition of stakeholders and designed a questionnaire that integrated the following influence factors, which have relevant impact on hospital management: political/legal, economic, social, technological and environmental forces. These influence factors are examined to develop the so-called critical uncertainties. Thorough identification of uncertainties was based on a “Stakeholder Feedback”. Results: Two key uncertainties were identified and considered in this study: the development of workload for the medical staff the profit oriented performance of the medical staff. According to the developed scenarios, complementary education of the medical staff as well as of non-medical top executives and managers of hospitals was the recommended core strategy. Complementary scenario-specific strategic options should be considered whenever needed to optimize dealing with a specific future development of the health care environment. Conclusion: Strategic planning in hospitals is essential to ensure sustainable success. It considers multiple situations and integrates internal and external insights and perspectives in addition to identifying weak signals and “blind spots”. This flows into a sound planning for multiple strategic options. It is a state of the art tool that allows dealing with the increasing challenges facing hospital management. PMID:26504735

    Acinetobacter baumannii can cause a serious infection in solid-organ transplant (SOT) recipients, and more data on A. baumannii infection is needed. We sought to investigate the epidemiology and distribution of A. baumannii isolates in SOT recipients. We also investigated the risk factors for overall in-hospital mortality and infection-related 30-day mortality using multivariate logistic regression analysis. A double-center retrospective study of SOT recipients who were infected with A. baumannii between January 2003 and January 2015 was conducted. A total of 71 individuals developed 93 episodes of A. baumannii infection, with a mean age of 44.5 years (44.5±11.9 years). Ninety percent of recipients had nosocomial origin A. baumannii infection, with the bloodstream as the most common site of infection (32.4%). Septic shock developed in 23.9% (17 of 71) of all recipients with A. baumannii infection. Morbidity and mortality rates of A. baumannii infections were high in SOT recipients. The incidence rate of A. baumannii infection in SOT recipients was 3.9% (71 of 1,821). Overall in-hospital mortality and infection-related 30-day mortality were 53.5% (38 of 71) and 40.8% (29 of 71), respectively. Risk factors independently associated with overall in-hospital mortality were mechanical ventilation at onset of A. baumannii infection (odds ratio [OR] 6.29, 95% confidence interval [CI] 1.48-26.85; P=0.013), liver or liver-kidney transplantation (OR 15.33, 95% CI 1.82-129.18; P=0.012), and late-onset A. baumannii infection (OR 7.61, 95% CI 1.07-54.36; P=0.043). A platelet count <50,000/mm(3) (OR 12.76, 95% CI 1.28-126.81; P=0.030) and mechanical ventilation at onset of A. baumannii infection (OR 189.98, 95% CI 13.23-2,728.81; P<0.001) were identified as independent risk factors for infection-related 30-day mortality. In conclusion, the morbidity and mortality rates of A. baumannii infections were high in SOT recipients. Mechanical ventilation at onset of A. baumannii

    In countries where induced abortion is legally restricted, as in most of Latin America, evaluation of statistics related to induced abortions and abortion-related mortality is challenging. The present article reexamines recent reports estimating the number of induced abortions and abortion-related mortality in Mexico, with special reference to the International Classification of Diseases (ICD). We found significant overestimations of abortion figures in the Federal District of Mexico (up to 10-fold), where elective abortion has been legal since 2007. Significant overestimation of maternal and abortion-related mortality during the last 20 years in the entire Mexican country (up to 35%) was also found. Such overestimations are most likely due to the use of incomplete in-hospital records as well as subjective opinion surveys regarding induced abortion figures, and due to the consideration of causes of death that are unrelated to induced abortion, including flawed denominators of live births. Contrary to previous publications, we found important progress in maternal health, reflected by the decrease in overall maternal mortality (30.6%) from 1990 to 2010. The use of specific ICD codes revealed that the mortality ratio associated with induced abortion decreased 22.9% between 2002 and 2008 (from 1.48 to 1.14 deaths per 100,000 live births). Currently, approximately 98% of maternal deaths in Mexico are related to causes other than induced abortion, such as hemorrhage, hypertension and eclampsia, indirect causes, and other pathological conditions. Therefore, only marginal or null effects would be expected from changes in the legal status of abortion on overall maternal mortality rates. Rather, maternal health in Mexico would greatly benefit from increasing access to emergency and specialized obstetric care. Finally, more reliable methodologies to assess abortion-related deaths are clearly required. PMID:23271925

    AIM: To evaluate the practice of nutritional assessment and management of hospitalised patients with cirrhosis and the impact of malnutrition on their clinical outcome. METHODS: This was a retrospective cohort study on patients with liver cirrhosis consecutively admitted to the Department of Gastroenterology and Hepatology at the Royal Adelaide Hospital over 24 mo. Details were gathered related to the patients’ demographics, disease severity, nutritional status and assessment, biochemistry and clinical outcomes. Nutritional status was assessed by a dietician and determined by subjective global assessment. Estimated energy and protein requirements were calculated by Simple Ratio Method. Intake was estimated from dietary history and/or food charts, and represented as a percentage of estimated daily requirements. Median duration of follow up was 14.9 (0-41.4) mo. RESULTS: Of the 231 cirrhotic patients (167 male, age: 56.3 ± 0.9 years, 9% Child-Pugh A, 42% Child-Pugh B and 49% Child-Pugh C), 131 (57%) had formal nutritional assessment during their admission and 74 (56%) were judged to have malnutrition. In-hospital caloric (15.6 ± 1.2 kcal/kg vs 23.7 ± 2.3 kcal/kg, P = 0.0003) and protein intake (0.65 ± 0.06 g/kg vs 1.01 ± 0.07 g/kg, P = 0.0003) was significantly reduced in patients with malnutrition. Of the malnourished cohort, 12 (16%) received enteral nutrition during hospitalisation and only 6 (8%) received ongoing dietetic review and assessment following discharge from hospital. The overall mortality was 51%, and was higher in patients with malnutrition compared to those without (HR = 5.29, 95%CI: 2.31-12.1; P < 0.001). CONCLUSION: Malnutrition is common in hospitalised patients with cirrhosis and is associated with higher mortality. Formal nutritional assessment, however, is inadequate. This highlights the need for meticulous nutritional evaluation and management in these patients. PMID:26668507

    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.

    Health care costs increase with prolonged in-hospital stays. Many factors influence the length of stay for patients with ST-elevation myocardial infarction (STEMI). In this study, we aimed to determine the differences between long-stay and early discharged patients with STEMI. For this retrospective study, a total of 2486 consecutive patients with STEMI (mean age: 56.2 ± 11.7 years, 16.5% female) who had undergone primary percutaneous coronary intervention (pPCI) were enrolled. Patients were divided into 2 groups based on mean in-hospital stay: <6 days and ≥6 days. Anterior STEMI (odds ratio [OR]: 1.61, 95% confidence interval [CI]: 1.02-2.54; P = 0.03), angiographic failure (OR: 2.89, 95% CI: 1.19-7.01; P = .01), and peripheral vascular complications (PVCs; OR: 4.18, 95% CI: 1.16-15.03; P = .02) were found to be independent predictors of ≥6-day in-hospital stay. The incidence of long-term total mortality and composite end point for death, reinfarction, and target vessel revascularization were significantly higher in ≥6-day in-hospital stay patients. Anterior STEMI, angiographic failure, and PVCs were found to be independently associated with prolonged in-hospital stay for patients with STEMI following pPCI. PMID:26582944

    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

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

  13. Autoantibodies, mortality and ageing.

    Immunological failure may be the cause of predisposition to certain infections, neoplasms, and vascular diseases in adulthood. Mortality risks through life may reflect an undetermined number of causes. This study describes the prevalence of positivity of autoantibodies through life, along with general and specific mortality causes in three countries with different socioeconomic development (Guatemala, Mexico and the United States). Prevalence of autoantibodies by age was obtained from previous reports. In spite of having involved different ethnic groups, the observed trends in prevalence of autoantibodies, as well as mortality through life, showed a similar behavior. Thus, both the increase in autoantibody production and death risk as age rises, may share physiopathological phenomena related to the ageing process. PMID:7539882

    OBJECTIVE. This study investigated how mortality differences between groups of municipal versus voluntary hospitals are affected by case-mix adjustment methods. DATA SOURCES AND STUDY SETTING. We sampled about 10,000 random admissions from administrative data for patients hospitalized with each of six conditions in hospitals in New York City during 1984-1987. STUDY DESIGN. We developed logistic regression models adjusting for age and gender, for principal diagnosis, for "limited other diagnoses" (secondary diagnoses that were very unlikely to result from care received), for "full other diagnoses" (all secondary diagnoses irrespective of whether they might have been due to care received), for previous diagnoses, and for other variables. PRINCIPAL FINDINGS. For five of the six conditions, when the limited other diagnoses adjustment was used there was higher mortality in the municipal hospitals (p < .05), with 3.3 additional deaths/100 admissions for myocardial infarction, 1.2 for pneumonia, 8.3 for stroke, 2.8 for head trauma, and 0.8 for hip repair. However, when the full other diagnoses adjustment was used, differences remained significant only for stroke (4.3 additional deaths/100 admissions) and head trauma (1.3) (p < .05). CONCLUSIONS. Estimates of mortality differences between New York City municipal and voluntary hospitals are substantially affected by which secondary diagnoses are used in case-mix adjustment. Judgments of quality should not be based on administrative data unless models can be developed that validly capture level of sickness at admission. PMID:8163382

    The burden of hospitalisations for obstructive lung diseases (OLD) has not been sufficiently studied. We aimed to characterise the hospitalisations for OLD from 2000 to 2010 in all Portuguese public hospitals. We analysed hospital discharges with a diagnosis of OLD regarding the patients' gender, age, residence and comorbidities. Of the 120 399 hospital admissions with a principal diagnosis of OLD, COPD (ICD-9-CM 491.x, 492.x, 496) was responsible for 81%. The change in patients discharged with OLD as a principal diagnosis was only 1% from 2000 to 2010 and did not change for COPD. Hospital admissions and deaths for COPD and other OLD increased with age and were more common in men than women. In-hospital mortality for COPD decreased 34.1% from 2000 to 2010, while the median length of stay was fairly constant at 8 days. Respiratory failure, insufficiency and/or arrest, and pneumonia, are the principal diagnoses often associated with COPD. When both pneumonia and COPD were diagnosed there was an increasing trend to classify pneumonia as the principal diagnosis (64.4%-72.9%), a sign that may lead to underestimation of COPD hospitalisations. In summary, a considerable decrease in in-hospital COPD mortality was observed while hospital admissions and the length of stay did not change substantially. These results suggest that better healthcare or other factors may be counteracting the expected increase of the burden of COPD. PMID:27296823

    The transmission of measles in medical settings has become increasingly recognized. Due to the lack of information on nosocomial measles in Mexico we performed a 14 year retrospective study at the Hospital Infantil de México Federico Gómez. The objectives of our study were: a) to determine the frequency of the disease in our hospital; b) to determine the association between nutritional status and risk of acquiring nosocomial measles and c) to establish the relationship between nutritional status and complications in morbidity and mortality due to nosocomial measles. Eighty nine children with nosocomial measles were identified. We observed that patients with severe malnutrition had a greater risk of acquiring nosocomial measles developing complication and dying. The most frequent complication was pneumonia. PMID:2206415

    Background and Purpose In-hospital stroke (IHS) differs from out-of-hospital stroke (OHS) in risk factors and outcomes. We compared IHS and OHS treated with thrombolysis from a large national cohort in a cross-sectional study to further clarify these differences. Methods The Nationwide Inpatient Sample for the years 2005 through 2010 was searched for adult acute ischemic stroke cases treated with intravenous or intra-arterial thrombolysis. Patients treated on the day of admission were classified as OHS. We compared the demographic and hospital characteristics, comorbidities, and short-term outcomes of thrombolysed IHS and OHS. Results IHS represented 8.7% of 11,750 thrombolysed stroke cases included in this study. IHS was associated with a higher comorbidity profile and higher rates of acute medical conditions compared to OHS. IHS had higher inpatient mortality (15.7% versus 9.6%; P<0.001) and lower rate of discharge to home/self-care (22.8% versus 30.0%; P<0.001). IHS was also associated with higher mortality among endovascular treatment group (19.3% versus 13.8%; P=0.010). The difference in the rate of all intracerebral hemorrhage (ICH) was not significant (5.3% versus 4.7%; P=0.361). In the multivariate analysis, inpatient mortality (adjusted OR, 1.59; 95% CI, 1.32–1.92; P<0.001) and favorable discharge outcome (adjusted OR, 0.79; 95% CI, 0.67–0.93; P=0.005) remained significantly worse in IHS. Conclusions Thrombolysed IHS is associated with worse discharge outcomes compared to thrombolysed OHS, likely due to their higher comorbidities and additional medical reasons for the index admission. Thrombolysis is not associated with a higher rate of ICH among IHS. PMID:23632981

  18. The changing power equation in hospitals.

    1997-01-01

    This research traces the origins, development, and reasons for change in the power equation in the U.S. hospitals between physicians, administrators and accountants. The paper contains three major sections: a review of the literature concerning authority, power, influence, and institutional theory; a review of the development of the power of professions, especially physicians, accounting and healthcare administrators, and the power equilibrium of a hospital; and, a discussion of the social policy implications of the power struggle. The basis for physicians' power derives from their legal ability to act on which others are dependent, such as choosing which hospital to admit patients, order tests and procedures for their patients. The Federal Government's prospective payment system and the hospitals' related case-mix accounting systems appear to influence the power structure in hospitals by redistributing that power. The basis of the accountants' power base is control of financial information. Accountants have a definite potential for influencing which departments receive financial resources and for what purpose. This moves hospital accountants into the power equation. The basis of the hospital administrators' power is their formal authority in the organization. Regardless of what actions federal government agencies, hospital accountants, or hospital administrators take, physicians are expected to remain the dominant factor in the power equation. Without major environmental changes to gain control of physician services, only insignificant results in cost containment will occur. PMID:10163913

    Mineral water (soda water) is very popular in Germany. Therefore, soda fountains were developed as alternatives to the traditional deposit bottle system. Nowadays, different systems of these devices are commercially available. For several years, soda fountains produced by different companies have been examined at the University Hospital of Heidelberg. In 1998, it was possible for the first time to observe and evaluate one of these systems over a period of 320 days in a series of microbiological examinations. The evaluation was implemented on the basis of the German drinking water regulation (Anonymous, 1990. Gesetz über Trinkwasser und Wasser für Lebensmittelbetriebe (Trinkwasserverordnung - TrinkwV) vom 12. Dezember 1990. Bundesgesetzblatt 66, 2613ff). Initially, the bacteria counts exceeded the reference values imposed by the German drinking water regulation in almost 50% of the analyses. Pseudomonas aeruginosa was also detected in almost 38% of the samples. After a re-arrangement of the disinfection procedure and the removal of the charcoal filter, Pseudomonas aeruginosa was not detectable any more. However, the bacteria counts still frequently exceeded the reference values of the German drinking water regulation. Following our long-term analysis, we would not recommend soda fountains in high-risk areas of hospitals. If these devices are to be used in hospitals, the disinfection procedures should be executed in weekly or fortnightly intervals and the water quality should be examined periodically. PMID:16740412

  20. Patient falls in hospitals: an increasing problem.

    PubMed

    Weil, Thomas P

    2015-01-01

    Despite six decades of worldwide efforts that include publishing virtually hundreds of related epidemiological-type studies, there has been an increase (estimated to be 46% per 1000 patient days from 1954-6 to 2006-10) in the number of patient falls in hospitals and other health care facilities. These still occur most frequently near the bedside or in the bathroom, among mentally confused or physically impaired patients, and often involve those with greater comorbidity. The reasons that hospitals during the past half century have demonstrated a significant increase in patient falls per discharge or per patient days are numerous, are not completely surprising, and are certainly interrelated: improved accident reporting systems; on the average older, more impaired, more acutely ill, and more heavily sedated patients; and, less time spent by nursing personnel at the bedside. Most safety committees are not as effective as they should be, since they have difficulty in implementing a long-term, aggressive, facility-wide prevention program. Within that context, it may be worthwhile to discuss the advantages of nursing leadership rather than a representative of the facility's management staff to chair these safety committees.

    Hospitals are hotspots for antimicrobial-resistant bacteria (ARB) and play a major role in both their emergence and spread. Large numbers of these ARB will be ejected from hospitals via wastewater systems. In this review, we present quantitative and qualitative data of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli, vancomycin-resistant enterococci and Pseudomonas aeruginosa in hospital wastewaters compared to community wastewaters. We also discuss the fate of these ARB in wastewater treatment plants and in the downstream environment. Published studies have shown that hospital effluents contain ARB, the burden of these bacteria being dependent on their local prevalence. The large amounts of antimicrobials rejected in wastewater exert a continuous selective pressure. Only a few countries recommend the primary treatment of hospital effluents before their discharge into the main wastewater flow for treatment in municipal wastewater treatment plants. Despite the lack of conclusive data, some studies suggest that treatment could favour the ARB, notably ESBL-producing E. coli. Moreover, treatment plants are described as hotspots for the transfer of antibiotic resistance genes between bacterial species. Consequently, large amounts of ARB are released in the environment, but it is unclear whether this release contributes to the global epidemiology of these pathogens. It is reasonable, nevertheless, to postulate that it plays a role in the worldwide progression of antibiotic resistance. Antimicrobial resistance should now be seen as an 'environmental pollutant', and new wastewater treatment processes must be assessed for their capability in eliminating ARB, especially from hospital effluents.

  4. Mortality and development revisited.

    PubMed

    Preston, S H

    1985-01-01

    This paper attempts to update results reported in 2 earlier papers about the role of socioeconomic factors in worldwide mortality declines since the 1930s. Preston (1975) demonstrated that the relationship between life expectancy at birth and per capita income (in constant dollars) had shifted between the 1930s and the 1960s. A country at a particular level of national income per capita was estimated to have a level of life expectancy at birth that was, on average, 9.7 years higher in the 1960s than it would have been in the 1930s at the same level of income. That shift clearly was attributable to factors other than measured income gains. To identify the contribution of advances in literacy and nutrition to the apparent shift, Preston (1980) added those variables to income in regression equations estimated with data on 36 countries around 1940 and 120 countries around 1970. For the less developed countries (LDCs), the shift in the relationship between 1940-70 was estimated to be 8.8 years after those variables were introduced along with income. Thus, literacy and nutritional gains were responsible for relatively little of the shift. The goal here is to estimate the amount of shift in the relation between mortality and other development indicators during the 1965-69 to 1975-79 period. The focus is on the 70% of the developing world (exclude China) where, in the aggregate, there are indications of a slowdown in the pace of mortality change during the 1960s and the early 1970s. In all cases a mortality indicator was used as the dependent variable in a cross-national regression analysis that includes data from LDCs and from developed countries. Also, in all cases, the set of independent variables included some transformation of the following: the percentage of adults who were literate, gross domestic product per capita in constant dollars, and the excess of per capita daily calories supplied above 1500. Data were drawn from the standard UN, UNESCO, and World Bank

  5. Unintentional injury mortality in India, 2005: Nationally representative mortality survey of 1.1 million homes

    2012-01-01

    Background Unintentional injuries are an important cause of death in India. However, no reliable nationally representative estimates of unintentional injury deaths are available. Thus, we examined unintentional injury deaths in a nationally representative mortality survey. Methods Trained field staff interviewed a living relative of those who had died during 2001-03. The verbal autopsy reports were sent to two of the130 trained physicians, who independently assigned an ICD-10 code to each death. Discrepancies were resolved through reconciliation and adjudication. Proportionate cause specific mortality was used to produce national unintentional injury mortality estimates based on United Nations population and death estimates. Results In 2005, unintentional injury caused 648 000 deaths (7% of all deaths; 58/100 000 population). Unintentional injury mortality rates were higher among males than females, and in rural versus urban areas. Road traffic injuries (185 000 deaths; 29% of all unintentional injury deaths), falls (160 000 deaths, 25%) and drowning (73 000 deaths, 11%) were the three leading causes of unintentional injury mortality, with fire-related injury causing 5% of these deaths. The highest unintentional mortality rates were in those aged 70years or older (410/100 000). Conclusions These direct estimates of unintentional injury deaths in India (0.6 million) are lower than WHO indirect estimates (0.8 million), but double the estimates which rely on police reports (0.3 million). Importantly, they revise upward the mortality due to falls, particularly in the elderly, and revise downward mortality due to fires. Ongoing monitoring of injury mortality will enable development of evidence based injury prevention programs. PMID:22741813

    Farm children face unique health risks due to sharing their residential environment with hazardous machinery and materials. Causes of mortality among farm children have not been comprehensively described. OBJECTIVE: In the Agricultural Health Study (AHS) cohort, we examined causes of mortality among 21,360 children in Iowa and North Carolina between 1975 and 1998. METHODS: We matched identifying information for children provided by mothers on self-administered questionnaires to state death registries (1975-1998). Data on farm and family characteristics were provided by parents via enrollment questionnaires (1993-1997). Standardized mortality ratios (SMRs) were calculated, using state mortality data to generate expected deaths. We used logistic regression to examine parent, child and farm characteristics associated with injury mortality. RESULTS: There were 162 deaths in Iowa (SMR=0.69; 95% confidence interval (CI)=0.60, 0.81) and 26 deaths in North Carolina (SMR=0.42; 95%CI=0.28, 0.61) in children aged 0-19 years. This deficit was largely due to deaths in the first year of life. Although deaths from overall unintentional injury were not increased, excess agricultural machinery mortality was observed in Iowa (SMR=9.25; 95% CI=5.12, 16.70). In case-control comparisons, maternal age less than 25 years at child's birth (OR=2.17; 95%CI=1.05, 4.49) and having more than 2 children in the family (OR=2.79; 95%CI=1.47, 5.30) were associated with increased child injury mortality. For children under 14 years, participation in farm work was associated with increased risk of agricultural machine-related mortality (OR=3.92; 95% CI=1.04, 14.78). CONCLUSIONS: Parent and child characteristics associated with child injury mortality could be used to target farm safety interventions. PMID:18535666

    Objective We devised a percutaneous coronary intervention (PCI) scoring system based on angiographic lesion complexity and assessed its association with in-hospital complications. Background Although PCI is finding increasing application in patients with coronary artery disease, lesion complexity can lead to in-hospital complications. Methods Data from 3692 PCI patients were scored based on lesion complexity, defined by bifurcation, chronic total occlusion, type C, and left main lesion, along with acute thrombus in the presence of ST-segment elevation myocardial infarction (1 point assigned for each variable). Results The patients’ mean age was 67.5 +/- 10.8 years; 79.8% were male. About half of the patients (50.3%) presented with an acute coronary syndrome, and 2218 (60.1%) underwent PCI for at least one complex lesion. The patients in the higher-risk score groups were older (p < 0.001) and had present or previous heart failure (p = 0.02 and p = 0.01, respectively). Higher-risk score groups had significantly higher in-hospital event rates for death, heart failure, and cardiogenic shock (from 0 to 4 risk score; 1.7%, 4.5%, 6.3%, 7.1%, 40%, p < 0.001); bleeding with a hemoglobin decrease of >3.0 g/dL (3.1%, 11.0%, 13.1%, 10.3%, 28.6%, p < 0.001); and postoperative myocardial infarction (1.5%, 3.1%, 3.8%, 3.8%, 10%, p = 0.004), respectively. The association with adverse outcomes persisted after adjustment for known clinical predictors (odds ratio 1.72, p < 0.001). Conclusion The complexity score was cumulatively associated with in-hospital mortality and complication rate and could be used for event prediction in PCI patients. PMID:26121583

    Aims: To evaluate the mortality experience of 1484 men employed in seven uranium mills in the Colorado Plateau for at least one year on or after 1 January 1940. Methods: Vital status was updated through 1998, and life table analyses were conducted. Results: Mortality from all causes and all cancers was less than expected based on US mortality rates. A statistically significant increase in non-malignant respiratory disease mortality and non-significant increases in mortality from lymphatic and haematopoietic malignancies other than leukaemia, lung cancer, and chronic renal disease were observed. The excess in lymphatic and haematopoietic cancer mortality was due to an increase in mortality from lymphosarcoma and reticulosarcoma and Hodgkin's disease. Within the category of non-malignant respiratory disease, mortality from emphysema and pneumoconioses and other respiratory disease was increased. Mortality from lung cancer and emphysema was higher among workers hired prior to 1955 when exposures to uranium, silica, and vanadium were presumably higher. Mortality from these causes of death did not increase with employment duration. Conclusions: Although the observed excesses were consistent with our a priori hypotheses, positive trends with employment duration were not observed. Limitations included the small cohort size and limited power to detect a moderately increased risk for some outcomes of interest, the inability to estimate individual exposures, and the lack of smoking data. Because of these limitations, firm conclusions about the relation of the observed excesses in mortality and mill exposures are not possible. PMID:14691274

    Emerging evidence suggests that minor changes in serum creatinine concentrations are associated with increased hospital mortality rates. However, whether serum creatinine concentration (SCr) on admission and its change are associated with an increased mortality rate in mechanically ventilated patients is not known. We have conducted an international, prospective, observational cohort study enrolling adult intensive care unit patients under mechanical ventilation (MV). Recursive partitioning was used to determine the values of SCr at the start of MV (SCr0) and the change in SCr ([DeltaSCr] defined as the maximal difference between the value at start of MV [day 0] and the value on MV day 2 at 8:00 am) that best discriminate mortality. In-hospital mortality, adjusted by a proportional hazards model, was the primary outcome variable. A total of 2,807 patients were included; median age was 59 years and median Simplified Acute Physiology Score II was 44. All-cause in-hospital mortality was 44%. The variable that best discriminated outcome was a SCr0 greater than 1.40 mg/dL (mortality, 57% vs. 36% for patients with SCr0 mortality (56% vs. 34%, P < 0.001). In multivariate analysis, geographic area, advanced age, severity of illness, reason for MV, and cardiovascular and hepatic failure were also associated with mortality. Our study suggests that SCr0 greater than 1.40 mg/dL and, in patients with low baseline SCr, a DeltaSCr greater than 0.31 are predictors of in-hospital mortality in mechanically ventilated patients.

    OBJECTIVE: To describe the prevalence of anemia and of its types in hospitalized patients with pulmonary tuberculosis. METHODS: This was a descriptive, longitudinal study involving pulmonary tuberculosis inpatients at one of two tuberculosis referral hospitals in the city of Rio de Janeiro, Brazil. We evaluated body mass index (BMI), triceps skinfold thickness (TST), arm muscle area (AMA), ESR, mean corpuscular volume, and red blood cell distribution width (RDW), as well as the levels of C-reactive protein, hemoglobin, transferrin, and ferritin. RESULTS: We included 166 patients, 126 (75.9%) of whom were male. The mean age was 39.0 ± 10.7 years. Not all data were available for all patients: 18.7% were HIV positive; 64.7% were alcoholic; the prevalences of anemia of chronic disease and iron deficiency anemia were, respectively, 75.9% and 2.4%; and 68.7% had low body weight (mean BMI = 18.21 kg/m2). On the basis of TST and AMA, 126 (78.7%) of 160 patients and 138 (87.9%) of 157 patients, respectively, were considered malnourished. Anemia was found to be associated with the following: male gender (p = 0.03); low weight (p = 0.0004); low mean corpuscular volume (p = 0.03);high RDW (p = 0; 0003); high ferritin (p = 0.0005); and high ESR (p = 0.004). We also found significant differences between anemic and non-anemic patients in terms of BMI (p = 0.04), DCT (p = 0.003), and ESR (p < 0.001). CONCLUSIONS: In this sample, high proportions of pulmonary tuberculosis patients were classified as underweight and malnourished, and there was a high prevalence of anemia of chronic disease. In addition, anemia was associated with high ESR and malnutrition. PMID:25210963

    In the last decade, many hospital designs have taken inspiration from hotels, spurred by factors such as increased patient and family expectations and regulatory or financial incentives. Increasingly, research evidence suggests the value of enhancing the physical environment to foster healing and drive consumer decisions and perceptions of service quality. Although interest is increasing in the broader applicability of numerous hospitality concepts to the healthcare field, the focus of this article is design innovations, and the services that such innovations support, from the hospitality industry. To identify physical hotel design elements and associated operational features that have been used in the healthcare arena, a series of interviews with hospital and hotel design experts were conducted. Current examples and suggestions for future hospitality elements were also sought from the experts, academic journals, and news articles. Hospitality elements applied in existing hospitals that are addressed in this article include hotel-like rooms and decor; actual hotels incorporated into medical centers; hotel-quality food, room service, and dining facilities for families; welcoming lobbies and common spaces; hospitality-oriented customer service training; enhanced service offerings, including concierges; spas or therapy centers; hotel-style signage and way-finding tools; and entertainment features. Selected elements that have potential for future incorporation include executive lounges and/or communal lobbies with complimentary wireless Internet and refreshments, centralized controls for patients, and flexible furniture. Although the findings from this study underscore the need for more hospitality-like environments in hospitals, the investment decisions made by healthcare executives must be balanced with cost-effectiveness and the assurance that clinical excellence remains the top priority.

  12. Impact of heat waves on mortality in Croatia

    2014-08-01

    The aim of this work was to determine the criteria for heat loads associated with an increase in mortality in different climatic regions of Croatia. The relationship between heat stress and mortality was analysed for the period 1983-2008. The input series is excess mortality defined as the deviations of mortality from expected values determined by means of a Gaussian filter of 183 days. The assessment of the thermal environment was performed by means of physiologically equivalent temperature (PET). The curve depicting the relationship between mortality and temperature has a U shape, with increased mortality in both the cold and warm parts of the scale but more pronounced in the warm part. The threshold temperature for increased mortality was determined using a scatter plot and fitting data by means of moving average of mortality; the latter is defined as the temperature at which excess mortality becomes significant. The values are higher in the continental part of Croatia than at the coast due to the refreshing influence of the sea during the day. The same analysis on a monthly basis shows that at the beginning of the warm season increased mortality occurs at a lower temperature compared with later on in the summer, and the difference is up to 15 °C between August and April. The increase in mortality is highest during the first 3-5 days and after that it decreases and falls below the expected value. Long-lasting heat waves present an increased risk, but in very long heat waves the increase in mortality is reduced due to mortality displacement.

    Mortality in patients with multiple sclerosis (MS) is significantly increased compared with the general population. Many questions concerning survival in MS are still unanswered due to the difficulty of comparing information collected at different times and in different geographic areas. The increasing incidence of MS, the improvement in care of the chronically disabled, and different methodologies may explain the lack of coherence among studies' results. Reported times to death from birth and from disease onset/diagnosis are highly variable. Patients older at onset or with primary progressive course have shorter survival; however, data on sex and mortality are contradictory. Changes in sex ratio in MS over time represent one possible explanation. MS is the main cause of death in ≥50% of patients and the incidence of deaths not due to MS varies among countries. Particularly, suicide is substantially increased in patients with MS, and, despite its varying incidence, mainly due to “cultural bias,” it should be considered an MS-related cause of death. Recent results of the long-term follow-up study of interferon-β-1b demonstrated a significant reduction of mortality among treated patients. Notwithstanding its long latency, mortality is therefore an unambiguously valid long-term outcome in randomized controlled trials. It usefully combines the net impact of treatment efficacy on longevity and adverse events, which may reduce it. PMID:23836941

    The authors present a continuation of the thesis suggesting that the most rational procedure for regulating fertility is a perfectly safe, even though not completely effective, contraceptive method combined with safe methods for terminating pregnancy when the contraceptive fails. This analysis demonstrates that, compared with the risk of death from pregnancy and childbirth, major reversible methods of fertility control--the pill, IUDs, condoms, and diaphragms--and abortion are associated with very low levels of mortality. The exception to this statement is pill use after age 40 by women who smoke. This analysis also confirms the very low mortality associated with using the condom and diaphragm with early induced abortion as a backup to terminate pregnancies resulting from contraceptive failures.

    Chronic diseases are increasing worldwide. Association of two or more chronic conditions is related with poor health status and reduced life expectancy, particularly among elderly patients. Comorbidities represent a risk factor for adverse events in several critical illnesses. We aimed to evaluate if elderly patients are affected by multiple chronic pathologies, assessed by Charlson comorbidity index (CCI), showed a reduced in-hospital survival after ischemic stroke. In a 3-year period, we evaluated all the subjects admitted to our internal medicine department for ischemic stroke. Age, sex, NIHSS score and all the comorbidities were recorded. Days of hospitalization, hospital-related infections and in-hospital mortality were also assessed. For each patient, we evaluated CCI, obtaining four classes: group 1 (CCI: 2-3), group 2 (CCI: 4-5), group 3 (CCI: 6-7) and group 4 (CCI: ≥8). Survival was evaluated with Kaplan-Meier and Cox regression analyses. The complete model considered in-hospital death as the main outcome, days of hospitalization as the time variable and CCI as the main predictor, adjusting for NIHSS, sex and nosocomial infections. Patients in CCI group 3 and 4 had an increased risk of in-hospital mortality, independently of NIHSS, sex and nosocomial infections. Elderly patients with multiple comorbidities have higher risk of in-hospital death when affected by ischemic stroke. PMID:27166707

    Background Mortality prediction models generally require clinical data or are derived from information coded at discharge, limiting adjustment for presenting severity of illness in observational studies using administrative data. Objectives To develop and validate a mortality prediction model using administrative data available in the first 2 hospital days. Research Design After dividing the dataset into derivation and validation sets, we created a hierarchical generalized linear mortality model that included patient demographics, comorbidities, medications, therapies, and diagnostic tests administered in the first 2 hospital days. We then applied the model to the validation set. Subjects Patients aged ≥18 years admitted with pneumonia between July 2007 and June 2010 to 347 hospitals in Premier, Inc.’s Perspective database. Measures In hospital mortality. Results The derivation cohort included 200,870 patients and the validation cohort had 50,037. Mortality was 7.2%. In the multivariable model, 3 demographic factors, 25 comorbidities, 41 medications, 7 diagnostic tests, and 9 treatments were associated with mortality. Factors that were most strongly associated with mortality included receipt of vasopressors, non-invasive ventilation, and bicarbonate. The model had a c-statistic of 0.85 in both cohorts. In the validation cohort, deciles of predicted risk ranged from 0.3% to 34.3% with observed risk over the same deciles from 0.1% to 33.7%. Conclusions A mortality model based on detailed administrative data available in the first 2 hospital days had good discrimination and calibration. The model compares favorably to clinically based prediction models and may be useful in observational studies when clinical data are not available. PMID:24498090

  20. Improving maternal care reduces mortality.

    PubMed

    1987-01-01

    Reduction of maternal mortality in developing countries by community-based action is complex but possible. Deaths related to pregnancy are primarily due to bleeding, infection, toxemia and illegal abortion. The excess maternal deaths in developing countries are also related to high numbers of high-risk pregnancies, total lack of prenatal and obstetric care in some areas, poor nutrition and overwork. The basic interventions available to communities include prenatal care, improved alarm and transport systems, referral centers and improved community-based care. Prenatal care can include nutritional supplements and exams and referrals by traditional birth attendants, targeting women suffering from toxemia, bleeding and infections. Local ambulances with life-support equipment, and maternity waiting houses are examples of ways of dealing with transport problems. Referral centers should be capable of providing sterile conditions and blood transfusions. Nurses can be trained to do caesarean sections. Birth attendants can use checklists to administer antibiotics and oxytocic drugs, for example. PMID:12281272

  1. Data base on animal mortality

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

  2. Nutrient Enrichment Increases Mortality of Mangroves

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

    Background/Aims: Data regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in nonagenarians are very limited. The aim of the present study was to evaluate the temporal trends and in-hospital outcomes of primary PCI in nonagenarian STEMI patients. Methods: We retrospectively reviewed data from the Korea Acute Myocardial Infarction Registry (KAMIR) from November 2005 to January 2008, and from the Korea Working Group on Myocardial Infarction (KorMI) from February 2008 to May 2010. Results: During this period, the proportion of nonagenarians among STEMI patients more than doubled (0.59% in KAMIR vs. 1.35% in KorMI), and the rate of use of primary PCI also increased (from 62.5% in KAMIR to 81.0% in KorMI). We identified 84 eligible study patients for which the overall in-hospital mortality rate was 21.4% (25.0% in KAMIR vs. 20.3% in KorMI, p = 0.919). Multivariate analysis identified two independent predictors of in-hospital mortality, namely a final Thrombolysis in Myocardial Infarction (TIMI) flow < 3 (odds ratio [OR], 13.7; 95% confidence interval [CI], 3.2 to 59.0; p < 0.001) and cardiogenic shock during hospitalization (OR, 6.7; 95% CI, 1.5 to 30.3; p = 0.013). Conclusions: The number of nonagenarian STEMI patients who have undergone primary PCI has increased. Although a final TIMI flow < 3 and cardiogenic shock are independent predictors of in-hospital mortality, primary PCI can be performed with a high success rate and an acceptable in-hospital mortality rate.

    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.

    Consider a group of subjects who are offered an opportunity to receive a sequence of periodic special examinations for the purpose of diagnosing a chronic disease earlier relative to usual care. The mortality for the early detection group is to be compared with a group receiving usual care. Benefit is reflected in a potential reduction in mortality. This article develops a general probability model that can be used to predict cumulative mortality for each of these groups. The elements of the model assume (i) a four-state progressive disease model in which a subject may be in a disease-free state (or a disease state that cannot be detected), preclinical disease state (capable of being diagnosed by a special exam), clinical state (diagnosis by usual care), and a death state; (ii) age-dependent transitions into the states; (iii) age-dependent examination sensitivity; (iv) age-dependent sojourn time in each state; and (v) the distribution of disease stages on diagnosis conditional on modality of detection. The model may be used to (i) compare mortality rates for different screening schedules; (ii) explore potential benefit of subpopulations; and (iii) compare relative reductions in disease-specific mortality due to advances and dissemination of both treatment and early detection screening programs.

    OBJECTIVE: After an inquiry from the employees of an offset printing plant, a historical cohort study was conducted to investigate cancer mortality among these workers. METHODS: The cohort comprised 262 men, who contributed 2771 person-years of observation. 16 deaths were identified during the follow up period (1980-91). Expected numbers of deaths were derived from age specific regional rates. Standardised mortality ratios (SMR) and 95% confidence intervals (95% CIs) were calculated. RESULTS: An increased cancer mortality was found after 10 years of employment (SMR 213, 95% CI 98 to 405, based on nine deaths), mainly due to a high mortality from lung cancer (SMR 381, 95% CI 104 to 975, four deaths), and from oesophageal cancer (SMR 1049, 95% CI 216 to 3065, three deaths). For workers with at least 20 years since the start of employment, the SMR was 262 (95% CI 105 to 540) for all cancer sites, 447 (95% CI 92 to 1306) for lung cancer, and 1094 (95% CI 132 to 3952) for oesophageal cancer. The increased cancer mortality was concentrated among pressmen. CONCLUSION: Although based on small numbers, the findings suggest an increased risk of cancer among these workers, which should be further investigated. PMID:9166132

    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.

    Background An association between pneumococcal serotypes and mortality has been suggested. We aimed to investigate this among individuals aged ≥15 years with invasive pneumococcal disease (IPD) in South Africa. Methods IPD cases were identified through national laboratory-based surveillance at 25 sites, pre-pneumococcal conjugate vaccine (PCV) introduction, from 2003–2008. We assessed the association between the 20 commonest serotypes and in-hospital mortality using logistic regression with serotype 4 (the third commonest serotype with intermediate case-fatality ratio (CFR)) as referent. Results Among 3953 IPD cases, CFR was 55% (641/1166) for meningitis and 23% (576/2484) for bacteremia (p<0.001). Serotype 19F had the highest CFR (48%, 100/207), followed by serotype 23F (39%, 99/252) and serotype 1 (38%, 246/651). On multivariable analysis, factors independently associated with mortality included serotype 1 (OR 1.9, 95%CI 1.1–3.5) and 19F (OR 2.9, 95%CI 1.4–6.1) vs. serotype 4; increasing age (25–44 years, OR 1.8, 95%CI 1.0–3.0; 45–64 years, OR 3.6, 95%CI 2.0–6.4; ≥65 years, OR 5.2, 95%CI 1.9–14.1; vs. 15–24 years); meningitis (OR 4.1, 95%CI 3.0–5.6) vs. bacteremic pneumonia; and HIV infection (OR1.7, 95%CI 1.0–2.8). On stratified multivariate analysis, serotype 19F was associated with increased mortality amongst bacteremic pneumococcal pneumonia cases, while no serotype was associated with increased mortality in meningitis cases. Conclusion Mortality was increased in HIV-infected individuals, which may be reduced by increased antiretroviral therapy availability. Serotypes associated with increased mortality are included in the 10-and-13-valent PCV and may become less common in adults due to indirect effects following routine infant immunization.

    Objective To compare in-hospital outcomes in aortic surgery in our cardiac surgery unit, before and after foundation of our Center for Aortic Surgery (CTA). Methods Prospective cohort with non-concurrent control. Foundation of CTA required specialized training of surgical, anesthetic and intensive care unit teams, routine neurological monitoring, endovascular and hybrid facilities, training of the support personnel, improvement of the registry and adoption of specific protocols. We included 332 patients operated on between: January/2003 to December/2007 (before-CTA, n=157, 47.3%); and January/2008 to December/2010 (CTA, n=175, 52.7%). Baseline clinical and demographic data, operative variables, complications and in-hospital mortality were compared between both groups. Results Mean age was 58±14 years, with 65% male. Group CTA was older, had higher rate of diabetes, lower rates of COPD and HF, more non-urgent surgeries, endovascular procedures, and aneurysms. In the univariate analysis, CTA had lower mortality (9.7 vs. 23.0%, P=0.008), which occurred consistently across different diseases and procedures. Other outcomes which were reduced in CTA included lower rates of reinterventions (5.7 vs 11%, P=0.046), major complications (20.6 vs. 33.1%, P=0.007), stroke (4.6 vs. 10.9%, P=0.045) and sepsis (1.7 vs. 9.6%, P=0.001), as compared to before-CTA. Multivariable analysis adjusted for potential counfounders revealed that CTA was independently associated with mortality reduction (OR=0.23, IC 95% 0.08 – 0.67, P=0.007). CTA independent mortality reduction was consistent in the multivariable analysis stratified by disease (aneurysm, OR=0.18, CI 95% 0.03 – 0.98, P=0.048; dissection, OR=0.31, CI 95% 0.09 – 0.99, P=0.049) and by procedure (hybrid, OR=0.07, CI 95% 0.007 – 0.72, P=0.026; Bentall, OR=0.18, CI 95% 0.038 – 0.904, P=0.037). Additional multivariable predictors of in-hospital mortality included creatinine (OR=1.7 [1.1-2.6], P=0.008), urgent surgery (OR=5

    Background Little is known about the relationship between age at menarche and total mortality and mortality from ischaemic heart disease and stroke. Methods A cohort study of 19 462 Californian Seventh-Day Adventist women followed-up from 1976 to 1988. A total of 3313 deaths occurred during follow-up, of which 809 were due to ischaemic heart disease and 378 due to stroke. Results An early menarche was associated with increased total mortality (P-value for linear trend <0.001), ischaemic heart disease (P-value for linear trend = 0.01) and stroke (P-value for linear trend = 0.02) mortality. There were, however, also some indications of an increased ischaemic heart disease mortality in women aged 16–18 at menarche (5% of the women). When assessed as a linear relationship, a 1-year delay in menarche was associated with 4.5% (95% CI 2.3–6.7) lower total mortality. The association was stronger for ischaemic heart disease [6.0% (95% CI 1.2–10.6)] and stroke [8.6% (95% CI 1.6–15.1)] mortality. Conclusions The results suggest that there is a linear, inverse relationship between age at menarche and total mortality as well as with ischaemic heart disease and stroke mortality. PMID:19188208

    Context Few studies have examined the association between the number of coronary heart disease risk factors and outcomes of acute myocardial infarction in community practice. Objective To determine the association between the number of coronary heart disease risk factors in patients with first myocardial infarction and hospital mortality. Design Observational study from the National Registry of Myocardial Infarction, 1994-2006. Patients We examined the presence and absence of 5 major traditional coronary heart disease risk factors (hypertension, smoking, dyslipidemia, diabetes, and family history of coronary heart disease) and hospital mortality among 542 008 patients with first myocardial infarction and without prior cardiovascular disease. Main Outcome Measure All-cause in-hospital mortality. Results A majority (85.6%) of patients who presented with initial myocardial infarction had at least 1 of the 5 coronary heart disease risk factors, and 14.4% had none of the 5 risk factors. Age varied inversely with the number of coronary heart disease risk factors, from a mean age of 71.5 years with 0 risk factors to 56.7 years with 5 risk factors (P for trend <.001). The total number of in-hospital deaths for all causes was 50 788. Unadjusted in-hospital mortality rates were 14.9%, 10.9%, 7.9%, 5.3%, 4.2%, and 3.6% for patients with 0, 1, 2, 3, 4, and 5 risk factors, respectively. After adjusting for age and other clinical factors, there was an inverse association between the number of coronary heart disease risk factors and hospital mortality adjusted odds ratio (1.54; 95% CI, 1.23-1.94) among individuals with 0 vs 5 risk factors. This association was consistent among several age strata and important patient subgroups. Conclusion Among patients with incident acute myocardial infarction without prior cardiovascular disease, in-hospital mortality was inversely related to the number of coronary heart disease risk factors.

    OBJECTIVE: The effect of socioeconomic factors on avoidable mortality at an individual level is not well known, since most studies showing this association are based on aggregate data. The purpose of this study was to determine socioeconomic differences between those patients who die of avoidable causes and those who do not die. METHODS: A matched case-control study was carried out regarding in-hospital avoidable mortality (Holland's medical care indicators) that occurred in a university hospital serving a Spanish-Mediterranean population during a 30-month period. RESULTS: We studied 82 cases of death from avoidable causes and 300 controls matched on medical care indicators and age. The variables that showed a statistically significant association with in-hospital avoidable mortality were number of diagnoses (the greater the number, the higher the risk), length of stay (patients staying seven or more days presented a lower risk), and education. Those patients with low and middle educational levels showed a greater risk of avoidable mortality (adjusted odds ratio=3.57 and 2.82, respectively) than those patients with higher levels of education. CONCLUSIONS: Consistent with the findings of studies based on aggregate data, our case-control analyses indicated that among several socioeconomic variables studied, educational level was significantly associated with the risk of in-hospital avoidable mortality, regardless of age and medical care indicators. Patients with low levels of education (<6 years of schooling) were at highest risk for in-hospital avoidable mortality, followed by those with middle levels of education (7-10 years of schooling).

    Accurate knowledge of a patient’s disease state and trajectory is critical in a clinical setting. Modern electronic healthcare records contain an increasingly large amount of data, and the ability to automatically identify the factors that influence patient outcomes stand to greatly improve the efficiency and quality of care. We examined the use of latent variable models (viz. Latent Dirichlet Allocation) to decompose free-text hospital notes into meaningful features, and the predictive power of these features for patient mortality. We considered three prediction regimes: (1) baseline prediction, (2) dynamic (time-varying) outcome prediction, and (3) retrospective outcome prediction. In each, our prediction task differs from the familiar time-varying situation whereby data accumulates; since fewer patients have long ICU stays, as we move forward in time fewer patients are available and the prediction task becomes increasingly difficult. We found that latent topic-derived features were effective in determining patient mortality under three timelines: inhospital, 30 day post-discharge, and 1 year post-discharge mortality. Our results demonstrated that the latent topic features important in predicting hospital mortality are very different from those that are important in post-discharge mortality. In general, latent topic features were more predictive than structured features, and a combination of the two performed best. The time-varying models that combined latent topic features and baseline features had AUCs that reached 0.85, 0.80, and 0.77 for in-hospital, 30 day post-discharge and 1 year post-discharge mortality respectively. Our results agreed with other work suggesting that the first 24 hours of patient information are often the most predictive of hospital mortality. Retrospective models that used a combination of latent topic features and structured features achieved AUCs of 0.96, 0.82, and 0.81 for in-hospital, 30 day, and 1-year mortality prediction. Our

    While the economic consequences of IMF programs have been extensively analyzed in the literature, much less is known about how key welfare indicators, including suicide-mortality rates, correlate with countries' participation in such programs. This paper examines the impact of IMF lending on suicide mortality, using data from 30 developing and transition countries that received non-concessionary IMF loans during 1991-2008. Our results support the hypothesis of a positive causal relationship between suicide mortality and participation in IMF programs but reveal no systematic suicide-increasing effect from the size of IMF loans. This holds after accounting for self-selection into programs, resulting from the endogeneity of a country's decision to resort to the IMF for funding, and after controlling for standard socio-economic influences on suicidal behaviour. In particular, we find a positive aggregate suicide-mortality differential due to IMF-program participation of between 4 and 14 percentage points. We also find that the positive association between suicides and program participation is stronger and more robust among males. Comparing age groups, individuals belonging to the age group 45-to-64 exhibit the highest increase in suicide due to program-participation, which amounts to over 18 percentage points. Overall, our results imply that when countries are exposed to IMF programs in an attempt to resolve their economic problems, social-safety nets need to be designed to protect the adversely-affected part of the population.

    Background Effective inpatient teaching requires intact patient memory, but studies suggest hospitalized adults may have memory deficits. Sleep loss among inpatients could contribute to memory impairment. Objective To assess memory in older hospitalized adults, and to test the association between sleep quantity, sleep quality and memory, in order to identify a possible contributor to memory deficits in these patients. Design Prospective cohort study Setting General medicine and hematology/oncology inpatient wards Patients 59 hospitalized adults at least 50 years of age with no diagnosed sleep disorder. Measurements Immediate memory and memory after a 24-hour delay were assessed using a word recall and word recognition task from the University of Southern California Repeatable Episodic Memory Test (USC-REMT). A vignette-based memory task was piloted as an alternative test more closely resembling discharge instructions. Sleep duration and efficiency overnight in the hospital were measured using actigraphy. Results Mean immediate recall was 3.8 words out of 15 (SD=2.1). Forty-nine percent of subjects had poor memory, defined as immediate recall score of 3 or lower. Median immediate recognition was 11 words out of 15 (IQR=9, 13). Median delayed recall score was 1 word and median delayed recognition was 10 words (IQR= 8–12). In-hospital sleep duration and efficiency were not significantly associated with memory. The medical vignette score was correlated with immediate recall (r=0.49, p<0.01) Conclusions About half of inpatients studied had poor memory while in the hospital, signaling that hospitalization might not be an ideal teachable moment. In-hospital sleep was not associated with memory scores. PMID:25872763

  18. Hyperparathyroidism: Cancer and Mortality

    PubMed Central

    Goswami, Soumik; Ghosh, Sujoy

    2012-01-01

    Hyperparathyroidism is a commoner endocrinopathy today with a large number of asymptomatic patients in contrast to the scenario five decades ago. Surgery is indicated for patients fulfilling the NIH criteria who are mostly symptomatic while individuals with mild disease are managed conservatively. Several studies indicate increased risk of malignancy involving several sites and related mortality in primary hyperparathyroidism (PHPT) with the risk persisting for several years after surgery. PHPT is associated with structural & functional cardiac abnormalities and premature death from increased cardiovascular disease with risk normalising only several years after surgery. Mortality risk is associated with pre-operative serum calcium & parathormone and parathyroid adenoma weight. However, the issue of existence of similar risk and surgical benefit in mild PHPT is mired in controversy although some studies have shown an association and beneficial trends with surgery. With current evidence, it would be prudent to follow up PHPT patients for malignancy and cardiovascular disease and possibly adopt a more liberal attitude towards surgery. PMID:23565381

  19. Accident mortality among children

    1956-01-01

    The authors present statistics on mortality from accidents, with special reference to those relating to the age-group 1-19 years. For a number of countries figures are given for the proportional mortality from accidents (the number of accident deaths expressed as a percentage of the number of deaths from all causes) and for the specific death-rates, per 100 000 population, from all causes of death, from selected causes, from all causes of accidents, and from various types of accident. From these figures it appears that, in most countries, accidents are becoming relatively increasingly prominent as a cause of death in childhood, primarily because of the conquest of other causes of death—such as infectious and parasitic diseases, which formerly took a heavy toll of children and adolescents—but also to some extent because the death-rate from motor-vehicle accidents is rising and cancelling out the reduction in the rate for other causes of accidental death. In the authors' opinion, further epidemiological investigations into accident causation are required for the purpose of devising quicker and more effective methods of accident prevention.

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

    2016-09-01

    Nonshockable rhythms, including pulseless electrical activity (PEA) and asystole, precede more than 70% of in-hospital cardiac arrests (I-HCA). Compared with shockable rhythms (ventricular fibrillation and ventricular tachycardia), nonshockable rhythms have higher mortality and morbidity. Therefore, investigating the underlying mechanisms of these arrhythmias to improve the quality of care and outcome for patients who suffer cardiac arrest is a priority. As the first responders to I-HCA, nurses must have the proper knowledge and training to provide timely and efficient cardiopulmonary resuscitation therapy. This article provides an overview of nonshockable cardiac arrhythmias preceding I-HCA as a means of addressing the gap between science and clinical practice. PMID:27484665

    Invasive infections due to carbapenem-resistant Enterobacteriaceae (CRE), including polymyxin-resistant (PR-CRE) strains, are being increasingly reported. However, there is a lack of clinical data for several life-threatening infections. Here we describe a cohort of patients with post-surgical mediastinitis due to CRE, including PR-CRE. This study was a retrospective cohort design at a single cardiology centre. Patients with mediastinitis due to CRE were identified and were investigated for clinically relevant variables. Infecting isolates were studied using molecular techniques. Patients infected with polymyxin-susceptible CRE (PS-CRE) strains were compared with those infected with PR-CRE strains. In total, 33 patients with CRE mediastinitis were studied, including 15 patients (45%) with PR-CRE. The majority (61%) were previously colonised. All infecting isolates carried blaKPC genes. Baseline characteristics of patients with PR-CRE mediastinitis were comparable with those with PS-CRE mediastinitis. Of the patients studied, 70% received at least one agent considered active in vitro and most patients received at least three concomitant antibiotics. Carbapenem plus polymyxin B was the most common antibiotic combination (73%). Over 90% of patients underwent surgical debridement. Overall, in-hospital mortality was 33% and tended to be higher in patients infected with PR-CRE (17% vs. 53%; P=0.06). In conclusion, mediastinitis due to CRE, including PR-CRE, can become a significant challenge in centres with CRE and a high cardiac surgery volume. Despite complex antibiotic treatments and aggressive surgical procedures, these patients have a high mortality, particularly those infected with PR-CRE. PMID:27155944

    All Canadian deaths due to malignant brain tumour for the years 1970-73 were identified and analysed for country of birth. The years 1970-73 were chosen since in later years country of birth was no longer available for each death. The brain tumour population consisted of 1551 male and 1058 female deaths and matched controls were chosen from deaths due to other causes. Americans who died of brain tumour in Canada had a standardized mortality ratio (SMR) of 1.0 compared to their fellow Americans in the USA. Italian, German, Dutch and British immigrants had SMR between 1.5 and 2.6 compared to rates in their home countries and between 1.24 and 2.09 when compared to Canadian rates. A series of graphs shows the increased risk for male immigrants quite dramatically, and indicates that for females the increases were less pronounced. Further analysis showed that the excess risk is confined to those who were born in Western Europe while their Canadian-born children experienced the same rates as all Canadians. Based on the limited information available, occupation could not be shown to play a role in establishing risk. An attempt was made to pinpoint the years of immigration which showed the greatest risk. It is concluded that the determination of risk of brain tumour has a strong environmental component. The possibilities for identification of this component are discussed. PMID:2722385

    Background Due to recent advances, door-to-balloon time (D2BT) has been reduced significantly for patients with ST-segment elevation myocardial infarction (STEMI). However, whether this reduction can be translated into a concrete mortality or morbidity benefit is still the subject of controversy. We conducted a before-and-after study to determine the impact of in-hospital tele-electrocardiography (ECG) triage and interventional cardiologist activation of the infarct team on D2BT and long-term clinical outcomes in STEMI patients undergoing primary percutaneous coronary intervention (PPCI). Methods A total of 272 consecutive patients with acute STEMI undergoing PPCI were enrolled in our study, comprising 102 tele-ECG patients and 170 conventional triage patients. Major adverse cardiovascular and cerebral vascular events (MACCE), including death, recurrent nonfatal MI, nonfatal stroke, and angina-driven target vessel revascularization were recorded during a 3-year follow-up. Results The median D2BT of the tele-ECG group was significantly shorter than control group (79 minutes vs. 109 minutes, p < 0.001). The tele-ECG triage group had a higher percentage of patients reaching the D2BT goal (< 90 minutes) (78% vs. 55%; p < 0.001). The MACCE rate was significantly lower in the Tele-ECG versus the control group (23.5% vs. 38.2%, p = 0.012). Tele-ECG group had a lower mortality rate which did not reached statistical significance (2% vs. 5.9%, p = 0.102). In multivariable Cox proportional hazards analyses, the implementation of tele-ECG triage (HR = 0.43, p = 0.003) and the presence of moderate or severe mitral regurgitation at presentation (HR = 1.87, p = 0.029) were discovered as independently associated with MACCE. Conclusions In-hospital tele-ECG triage and interventional cardiologist activation can shorten D2BT and is associated with improved late clinical outcomes during a 3-year follow-up in STEMI patients undergoing PPCI.

    Indigenous populations experience higher rates of poverty, disease and mortality than non-indigenous populations. To gauge current and future risks among Tsimane Amerindians of Bolivia, I assess mortality rates and growth early in life, and changes in risks due to modernization, based on demographic interviews conducted Sept. 2002–July 2005. Tsimane have high fertility (Total Fertility Rate = 9) and infant mortality (13%). Infections are the leading cause of infant death (55%). Infant mortality is greatest among women who are young, monolingual, space births close together, and live far from town. Infant mortality declined during the period 1990–2002, and a higher rate of reported miscarriages occurred during the 1950–1989 period. Infant deaths are more frequent among those born in the wet season. Infant stunting, underweight and wasting are common (34%, 15% and 12%, respectively) and greatest for low-weight mothers and high parity infants. Regression analysis of infant growth shows minimal regional differences in anthropometrics but greater stunting and underweight during the first two years of life. Males are more likely to be underweight, wasted, and spontaneously aborted. Whereas morbidity and stunting are prevalent in infancy, greater food availability later in life has not yet resulted in chronic diseases (e.g. hypertension, atherosclerosis and diabetes) in adulthood due to the relatively traditional Tsimane lifestyle.

  7. Effects of auditing patient safety in hospital care: design of a mixed-method evaluation

    PubMed Central

    2013-01-01

    Background Auditing of patient safety aims at early detection of risks of adverse events and is intended to encourage the continuous improvement of patient safety. The auditing should be an independent, objective assurance and consulting system. Auditing helps an organisation accomplish its objectives by bringing a systematic, disciplined approach to evaluating and improving the effectiveness of risk management, control, and governance. Audits are broadly conducted in hospitals, but little is known about their effects on the behaviour of healthcare professionals and patient safety outcomes. This study was initiated to evaluate the effects of patient safety auditing in hospital care and to explore the processes and mechanisms underlying these effects. Methods and design Our study aims to evaluate an audit system to monitor and improve patient safety in a hospital setting. We are using a mixed-method evaluation with a before-and-after study design in eight departments of one university hospital in the period October 2011–July 2014. We measure several outcomes 3 months before the audit and 15 months after the audit. The primary outcomes are adverse events and complications. The secondary outcomes are experiences of patients, the standardised mortality ratio, prolonged hospital stay, patient safety culture, and team climate. We use medical record reviews, questionnaires, hospital administrative data, and observations to assess the outcomes. A process evaluation will be used to find out which components of internal auditing determine the effects. Discussion We report a study protocol of an effect and process evaluation to determine whether auditing improves patient safety in hospital care. Because auditing is a complex intervention targeted on several levels, we are using a combination of methods to collect qualitative and quantitative data about patient safety at the patient, professional, and department levels. This study is relevant for hospitals that want to

    Background Relatively little contemporary data are available that describe differences in acute heart failure (AHF) hospitalization expenditures as a function of patient and hospital characteristics, especially from a population-based investigation. This study aimed to evaluate factors associated with variations in hospital expenditures for AHF in the United States. Methods A cross-sectional analysis using discharge data from the 2011 Nationwide Inpatient Sample, Healthcare Cost and Utilization Project, was conducted. Discharges with primary International Classification of Diseases, Ninth Revision, Clinical Modification, diagnosis codes for AHF in adults were included. Costs were estimated by converting Nationwide Inpatient Sample charge data using the Healthcare Cost and Utilization Project Cost-to-Charge Ratio File. Discharges with highest (≥80th percentile) versus lowest (≤20th percentile) costs were compared for patient characteristics, hospital characteristics, utilization of procedures, and outcomes. Results Of the estimated 1 million AHF hospital discharges, the mean cost estimates were $10,775 per episode. Younger age, higher percentage of obesity, atrial fibrillation, pulmonary disease, fluid/electrolyte disturbances, renal insufficiency, and greater number of cardiac/noncardiac procedures were observed in stays with highest versus lowest costs. Highest-cost discharges were more likely to be observed in urban and teaching hospitals. Highest-cost AHF discharges also had 5 times longer length of stay, were 9 times more costly, and had higher in-hospital mortality (5.6% vs 3.5%) compared with discharges with lowest costs (all P < .001). Conclusions Acute heart failure hospitalizations are costly. Expenditures vary markedly among AHF hospitalizations in the United States, with substantial differences in patient and hospital characteristics, procedures, and in-hospital outcomes among discharges with highest compared with lowest costs.

    COPD exacerbations resulting in hospitalization are accompanied by high mortality and morbidity. The contribution of specific co-morbidities to acute outcomes is not known in detail: existing studies have used either administrative data or small clinical cohorts and have provided conflicting results. Identification of co-existent diseases that affect outcomes provides opportunities to address these conditions proactively and improve overall COPD care. Cases were identified prospectively on admission then underwent retrospective case note audit to collect data including co-morbidities on up to 60 unselected consecutive acute COPD admissions between March and May in each hospital participating in the 2008 UK National COPD audit. Outcomes recorded were death in hospital, length of stay, and death and readmission at 90 days after index admission. 232 hospitals collected data on 9716 patients, mean age 73, 50% male, mean FEV1 42% predicted. Prevalence of co-morbidities were associated with increased age but better FEV1 and ex-smoker status and with worse outcomes for all four measures. Hospital mortality risk was increased with cor pulmonale, left ventricular failure, neurological conditions and non-respiratory malignancies whilst 90 day death was also increased by lung cancer and arrhythmias. Ischaemic and other heart diseases were important factors in readmission. This study demonstrates that co-morbidities adversely affect a range of short-term patient outcomes related to acute admission to hospital with exacerbations of COPD. Recognition of relevant accompanying diseases at admission provides an opportunity for specific interventions that may improve short-term prognosis. PMID:21864116

    Weekend admission is associated with higher in-hospital mortality than weekday admission. Whether providing enhanced weekend staffing for acute medical inpatient services reduces mortality or length of stay is unknown. Methods This paper describes a retrospective analysis of in-hospital mortality and length of stay before and after introduction of an enhanced, consultant-led weekend service in acute medicine in November 2012. In-hospital mortality was compared for matching admission calendar months before and after introduction of the new service, adjusted for case volume. Length of stay and 30-day postdischarge mortality were also compared; illness severity of patients admitted was assessed by cross-sectional acuity audits. Results Admission numbers increased from 6,304 (November 2011-July 2012) to 7,382 (November 2012-July 2013), with no change in acuity score in elderly medical patients but a small fall in younger patients. At the same time, however, a 57% increase in early-warning score triggered calls was seen in 2013 (410 calls vs 262 calls in 2012; p<0.01). Seven-day consultant working was associated with a reduction in in-hospital mortality from 11.4% to 8.8% (p<0.001). Mortality within 30 days of discharge fell from 2.4% to 2.0% (p=0.12). Length of stay fell by 1.9 days (95% CI 1.1-2.7; p=0.004) for elderly medicine wards and by 1.7 days (95% CI 0.8-2.6; p=0.008) for medical wards. Weekend discharges increased from general medical wards (from 13.6% to 18.8%, p<0.001) but did not increase from elderly medicine wards. Conclusions Introduction of an enhanced, consultant-led model of working at weekends was associated with reduced in-hospital and 30-day post discharge mortality rates as well as reduced length of stay. These results require confirmation in rigorously designed prospective studies. PMID:27070886

    Abstract In acute aortic syndromes (AAS), organ malperfusion represents a key event impacting both on diagnosis and outcome. Increased levels of plasma lactate dehydrogenase (LDH), a biomarker of malperfusion, have been reported in AAS, but the performance of LDH for the diagnosis of AAS and the relation of LDH with outcome in AAS have not been evaluated so far. This was a bi-centric prospective diagnostic accuracy study and a cohort outcome study. From 2008 to 2014, patients from 2 Emergency Departments suspected of having AAS underwent LDH assay at presentation. A final diagnosis was obtained by aortic imaging. Patients diagnosed with AAS were followed-up for in-hospital mortality. One thousand five hundred seventy-eight consecutive patients were clinically eligible, and 999 patients were included in the study. The final diagnosis was AAS in 201 (20.1%) patients. Median LDH was 424 U/L (interquartile range [IQR] 367–557) in patients with AAS and 383 U/L (IQR 331–460) in patients with alternative diagnoses (P < 0.001). Using a cutoff of 450 U/L, the sensitivity of LDH for AAS was 44% (95% confidence interval [CI] 37–51) and the specificity was 73% (95% CI 69–76). Overall in-hospital mortality for AAS was 23.8%. Mortality was 32.6% in patients with LDH ≥ 450 U/L and 16.8% in patients with LDH < 450 U/L (P = 0.006). Following stratification according to LDH quartiles, in-hospital mortality was 12% in the first (lowest) quartile, 18.4% in the second quartile, 23.5% in the third quartile, and 38% in the fourth (highest) quartile (P = 0.01). LDH ≥ 450 U/L was further identified as an independent predictor of death in AAS both in univariate and in stepwise logistic regression analyses (odds ratio 2.28, 95% CI 1.11–4.66; P = 0.025), in addition to well-established risk markers such as advanced age and hypotension. Subgroup analysis showed excess mortality in association with LDH ≥ 450 U/L in elderly, hemodynamically stable

  13. Trends in elderly mortality in the Nordic countries.

    1987-12-01

    This study describes the development of elderly mortality in the Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) during this century. Long-term trends in total mortality are examined on the basis of life table statistics. More recent trends (from the 1950s onwards) are described by means of annual mortality rates according to a rough classification of causes of death. The series of vital statistics have been utilized as the data source for the long-term trends, and the original data for annual trends have been obtained from the mortality data bank files of the WHO. Marked improvements were observed in survival at advanced ages in the Nordic countries. However, the development has not been stable as in recent decades the elderly mortality rate has fluctuated, roughly comparable to the fluctuations in mortality among the younger age groups. The fact that the rate of recent improvement has been greatest in Finland where there, traditionally, is a high mortality level, and low in Norway and Sweden, where mortality levels are low, is in accordance with the idea of approaching a certain biological lower limit to mortality. However, certain characteristics seem to suggest that further advances are possible. Marked improvements have taken place recently in Iceland even though its mortality level at the end of the 1960s was already low. In addition, a large proportion of the differences in mortality rates between the Nordic countries may be due to external factors related to living conditions or life-style. Recent trends in mortality from several causes of death may also be primarily linked to such factors. Further research focusing particularly on a more detailed classification of causes of death and sociodemographic differentials within the national elderly populations is suggested. PMID:3502918

    AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt (TIPS) in 15 years. METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality. RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospital mortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients (OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients (OR = 1.347 vs non-transferred, P < 0.001), emergency admissions (OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region (OR = 1.449 vs West, P < 0.001) had significantly higher odds of in-hospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death (OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure (OR = 8.246), acute kidney failure (OR = 4.359), hepatic encephalopathy (OR = 2.217) and esophageal variceal bleeding (OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites (OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders (OR = 2.823), coagulopathy (OR = 2.016), and lymphoma (OR = 1.842). CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay

    Epilepsy is associated with a high rate of premature mortality from direct and indirect effects of seizures, epilepsy, and antiseizure therapies. Sudden unexpected death in epilepsy (SUDEP) is the second leading neurologic cause of total lost potential life-years after stroke, yet SUDEP may account for less than half of all epilepsy-related deaths. Some epilepsy groups are especially vulnerable: individuals from low socioeconomic status groups and those with comorbid psychiatric illness die more often than controls. Despite clear evidence of an important public health problem, efforts to assess and prevent epilepsy-related deaths remain inadequate. We discuss factors contributing to the underestimation of SUDEP and other epilepsy-related causes of death. We suggest the need for a systematic classification of deaths directly due to epilepsy (e.g., SUDEP, drowning), due to acute symptomatic seizures, and indirectly due to epilepsy (e.g., suicide, chronic effects of antiseizure medications). Accurately estimating the frequency of epilepsy-related mortality is essential to support the development and assessment of preventive interventions. We propose that educational interventions and public health campaigns targeting medication adherence, psychiatric comorbidity, and other modifiable risk factors may reduce epilepsy-related mortality. Educational campaigns regarding sudden infant death syndrome and fires, which kill far fewer Americans than epilepsy, have been widely implemented. We have done too little to prevent epilepsy-related deaths. Everyone with epilepsy and everyone who treats people with epilepsy need to know that controlling seizures will save lives. PMID:26674330

    The importance of glycemic control in hospitalized patients has been a relatively recent revelation. There is somewhat contradictory evidence concerning the optimal glycemic target in critically ill patients. There is only indirect evidence in non-critically ill patients. This article reviews the evidence for glycemic targets in hospitalized patients. It also investigates which hospital-based treatments can act as barriers to attaining optimal blood glucose levels in hospital and system barriers to attaining those optimal levels. The systematic approach to and evaluation of in-hospital diabetes management has a short history. The first large clinical trial, the DIGAMI trial of peri-myocardial infarction insulin therapy, was published in 1995 (1). The first guideline discussion of in-hospital diabetes management occurred briefly in 2003, more fully in 2008 and 2013 (2-4) by the Canadian Diabetes Association; in 2005 and annually since then by the American Diabetes Association (5,6). Recently, there have been many more publications on the topic. A recent PubMed search, limited to the last 5 years, "hospital" and "diabetes" as a Medical Subject Headings (MeSH) major topic, revealed more than 5000 English-language clinical trials (PubMed.gov; accessed 6 Oct 2013). Still, relatively little is certain about appropriate glycemic targets in hospital. This has left us, in 2014, with consensus recommendations only for glycemic targets in non-critically ill patients from both the Canadian Diabetes Association Clinical Practice Guidelines (4) and the American Diabetes Association Standards of Medical Care in Diabetes (6). This article reviews recommended glycemic targets in various in-hospital populations and the barriers to obtaining them. PMID:24690500

    Background Each year, 200,000 patients undergo an in-hospital cardiac arrest (IHCA), with approximately 15–20% surviving to discharge. Little is known, however, about the long-term prognosis of these patients after discharge. Previous efforts to describe out-of-hospital survival of IHCA patients have been limited by small sample sizes and narrow patient populations Methods A single institution matched cohort study was undertaken to describe mortality following IHCA. Patients surviving to discharge following an IHCA between 2008 and 2010 were matched on age, sex, race and hospital admission criteria with non-IHCA hospital controls and follow-up between 9 and 45 months. Kaplan–Meier curves and Cox PH models assessed differences in survival. Results Of the 1262 IHCAs, 20% survived to hospital discharge. Of those discharged, survival at 1 year post-discharge was 59% for IHCA patients and 82% for controls (p < 0.0001). Hazard ratios (IHCA vs. controls) for mortality were greatest within the 90 days following discharge (HR = 2.90, p < 0.0001) and decreased linearly thereafter, with those surviving to one year post-discharge having an HR for mortality below 1.0. Survival after discharge varied amongst IHCA survivors. When grouped by discharge destination, out of hospital survival varied; in fact, IHCA patients discharged home without services demonstrated no survival difference compared to their non-IHCA controls (HR 1.10, p = 0.72). IHCA patients discharged to long-term hospital care or hospice, however, had a significantly higher mortality compared to matched controls (HR 3.91 and 20.3, respectively; p < 0.0001). Conclusion Among IHCA patients who survive to hospital discharge, the highest risk of death is within the first 90 days after discharge. Additionally, IHCA survivors overall have increased long-term mortality vs. controls. Survival rates were varied widely with different discharge destinations, and those discharged to home, skilled nursing facilities or to

    Survival after in-hospital cardiac arrest (I-HCA) remains < 30 %. There is very limited literature exploring the electrocardiogram changes prior to I-HCA. The purpose of the study was to determine demographics and electrocardiographic predictors prior to I-HCA. A retrospective study was conducted among 39 cardiovascular subjects who had cardiopulmonary resuscitation from I-HCA with initial rhythms of pulseless electrical activity (PEA) and asystole. Demographics including medical history, ejection fraction, laboratory values, and medications were examined. Electrocardiogram (ECG) parameters from telemetry were studied to identify changes in heart rate, QRS duration and morphology, and time of occurrence and location of ST segment changes prior to I-HCA. Increased age was significantly associated with failure to survive to discharge (p < 0.05). Significant change was observed in heart rate including a downtrend of heart rate within 15 min prior to I-HCA (p < 0.05). There was a significant difference in heart rate and QRS duration during the last hour prior to I-HCA compared to the previous hours (p < 0.05). Inferior ECG leads showed the most significant changes in QRS morphology and ST segments prior to I-HCA (p < 0.05). Subjects with an initial rhythm of asystole demonstrated significantly greater ECG changes including QRS morphology and ST segment changes compared to the subjects with initial rhythms of PEA (p < 0.05). Diagnostic ECG trends can be identified prior to I-HCA due to PEA and asystole and can be further utilized for training a predictive machine learning model for I-HCA. PMID:25236259

  20. Differentiating innovation priorities among stakeholder in hospital care

    PubMed Central

    2013-01-01

    Background Decisions to adopt a particular innovation may vary between stakeholders because individual stakeholders may disagree on the costs and benefits involved. This may translate to disagreement between stakeholders on priorities in the implementation process, possibly explaining the slow diffusion of innovations in health care. In this study, we explore the differences in stakeholder preferences for innovations, and quantify the difference in stakeholder priorities regarding costs and benefits. Methods The decision support technique called the analytic hierarchy process was used to quantify the preferences of stakeholders for nine information technology (IT) innovations in hospital care. The selection of the innovations was based on a literature review and expert judgments. Decision criteria related to the costs and benefits of the innovations were defined. These criteria were improvement in efficiency, health gains, satisfaction with care process, and investments required. Stakeholders judged the importance of the decision criteria and subsequently prioritized the selected IT innovations according to their expectations of how well the innovations would perform for these decision criteria. Results The stakeholder groups (patients, nurses, physicians, managers, health care insurers, and policy makers) had different preference structures for the innovations selected. For instance, self-tests were one of the innovations most preferred by health care insurers and managers, owing to their expected positive impacts on efficiency and health gains. However, physicians, nurses and patients strongly doubted the health gains of self-tests, and accordingly ranked self-tests as the least-preferred innovation. Conclusions The various stakeholder groups had different expectations of the value of the nine IT innovations. The differences are likely due to perceived stakeholder benefits of each innovation, and less to the costs to individual stakeholder groups. This study

    Ethiopia’s childhood mortality has continued to decline although at a swift pace. The drop in urban childhood mortality decline, duration of breastfeeding is the principle reason for the overall decline in mortality trends in Ethiopia. Data from the Ethiopian Demographic and Health Surveys 2000 and 2005 were used. Indirect estimation of Brass and Trussell’s methods were adopted. Selected demographic and socio-economic variables were included in the analysis with statistically significant effects. Findings clearly show neonatal and post neonatal mortality decline gradually. Even though, Ethiopia’s childhood mortality rates are still high. The result shows less than 2 years birth interval have higher infant mortality rates than higher birth interval (113 deaths per 1000). The proper spacing of births allows more time for childcare to make more maternal resources available for the care of the child and mother. Therefore, further research is urgent for regional level and national level investigation. PMID:23113145

    The present study describes cause-specific mortality of asbestos cement workers in the Emilia Romagna region of Italy. The cohort included workers in ten factories, most of which started operating between 1955 and 1965. Asbestos, mainly chrysotile, constituted 10%-20% of the dry component of the mixture. Crocidolite range between 5% and 50% of total asbestos. Asbestos concentrations up to 44 ff/cc were reported prior to 1975, while in recent years they have usually been below 0-1 ff/cc. The cohort included 3341 workers who had at some time been employed in the ten factories under study. Their mortality experience was compared with that of the population resident in Emilia Romagna. Vital status was ascertained at 1989. Seventy-three subjects were lost to follow-up (2.2%). Mortality from all causes and from all types of cancer was increased in the cohort. Malignant neoplasms of the respiratory tract showed a significant increase (SMR: 134; 90% confidence interval: 101-175; 40 observed) due to lung cancer (SMR: 124; 90% confidence interval: 91-166; 33 observed) and neoplasms of the pleura, mediastinum, and other parts of the respiratory tract (SMR: 602; 90% confidence interval 237-1267; 5 observed). The discrepancy between observed and expected mortality mainly concerned subjects with at least 20 years of employment in the factories. Five more cases of histologically confirmed mesothelioma occurred after the end of follow-up. PMID:7927845

    To examine patterns of death in lead smelter workers, a retrospective analysis of mortality was conducted in a cohort of 1,987 males employed between 1940 and 1965 at a primary lead smelter in Idaho. Overall mortality was similar to that of the United States white male population (standardized mortality ratio (SMR) = 98). Excess mortality, however, was found from chronic renal disease (SMR = 192; confidence interval (CI) = 88-364), and the risk of death from renal disease increased with increasing duration of employment, such that after 20 years employment, the standardized mortality ratio reached 392 (CI = 107-1,004). Excess mortality was also noted for nonmalignant respiratory disease (SMR = 187, CI = 128-264). Eight of 32 deaths in this category were caused by silicosis; at least five workers who died of silicosis had been miners for a part of their lives. An additional 11 deaths resulted from tuberculosis (SMR = 139; CI = 69-249); in six of these cases, silicosis was a contributory cause of death. Cancer mortality was not increased overall (SMR = 95; CI = 78-114). An increase, however, was noted for deaths from kidney cancer (six cases; SMR = 204; CI = 75-444). Finally, excess mortality was noted for injuries (SMR = 138; CI = 104-179); 13 (23%) of the 56 deaths in this category were caused by mining injuries. The data from this study are consistent with previous reports of increased mortality from chronic renal disease in persons exposed occupationally to lead. PMID:4025307

    Background The association of chronic renal insufficiency with outcomes after percutaneous coronary intervention (PCI) in the current era of drug-eluting stents and modern antithrombotic therapy has not been well characterized. Methods and Results We queried the 2007–2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years who underwent PCI. Multivariable logistic regression was used to compare in-hospital outcomes among patients with chronic kidney disease (CKD), patients with end-stage renal disease (ESRD), and those without CKD or ESRD. Of 3 187 404 patients who underwent PCI, 89% had no CKD/ESRD; 8.6% had CKD; and 2.4% had ESRD. Compared to patients with no CKD/ESRD, patients with CKD and patients with ESRD had higher in-hospital mortality (1.4% versus 2.7% versus 4.4%, respectively; adjusted odds ratio for CKD 1.15, 95% CI 1.12 to 1.19, P<0.001; adjusted odds ratio for ESRD 2.29, 95% CI 2.19 to 2.40, P<0.001), higher incidence of postprocedure hemorrhage (3.5% versus 5.4% versus 6.0%, respectively; adjusted odds ratio for CKD 1.21, 95% CI 1.18 to 1.23, P<0.001; adjusted odds ratio for ESRD 1.27, 95% CI 1.23 to 1.32, P<0.001), longer average length of stay (2.9 days versus 5.0 days versus 6.4 days, respectively; P<0.001), and higher average total hospital charges ($60 526 versus $77 324 versus $97 102, respectively; P<0.001). Similar results were seen in subgroups of patients undergoing PCI for acute coronary syndrome or stable ischemic heart disease. Conclusions In patients undergoing PCI, chronic renal insufficiency is associated with higher in-hospital mortality, higher postprocedure hemorrhage, longer average length of stay, and higher average hospital charges.

    We investigate the relationship between mortality and business cycles within Mexico, where development varies significantly. We exploit this variation by separately analyzing the top ten and bottom ten developed states for the period 1993-2004. We find that while overall mortality is procyclical nationally and in the top ten states, it is countercyclical in the bottom ten. Further, we show that in the top ten states mortality due to non communicable conditions is procyclical, while in the bottom ten mortality due to non communicable conditions and infectious and parasitic diseases are countercyclical. Our results suggest that the relationship between mortality and business cycles may vary by level of development. PMID:21074307

    OBJECTIVE: To conceptualize community orientation-defined as the generation, dissemination, and use of community health-need intelligence-as a strategic response to environmental pressures, and to test a theoretically justified model of the predictors of community orientation in hospitals. DATA SOURCES: The analysis used data for 4,578 hospitals obtained from the 1994 and 1995 American Hospital Association (AHA) Annual Survey and the 1994 Medicare Hospital Cost Report data sets. Market-level data came from the Area Resource File. STUDY DESIGN: Multiple regression analysis was used to examine the effects of hospital size, dependence on managed care, ownership, network, system and alliance memberships, and level of diffusion of community-orientation practices in the area on the degree of community orientation in hospitals. The model, based on Oliver's (1991) framework of organizational responsiveness to environmental pressures, controlled for the effects of industry concentration and lagged profitability. PRINCIPAL FINDINGS: Degree of community orientation is significantly related to hospital size; ownership; dependence on managed care; and membership in a network, system, or alliance. It is also significantly related to the diffusion of community-orientation practices among other area hospitals. CONCLUSIONS: Degree of community orientation is influenced by the nature of environmental pressures and by hospital interests. It is higher in hospitals that are large, nonprofit, or members of a network, system, or alliance; in hospitals that are more dependent on managed care; and in hospitals that operate in areas with higher diffusion of community-orientation activities.

    OBJECTIVE: To ascertain the role of low birth weight (LBW) in neonatal mortality in a periurban setting in Bangladesh. METHODS: LBW neonates were recruited prospectively and followed up at one month of age. The cohort of neonates were recruited after delivery in a hospital in Dhaka, Bangladesh, and 776 were successfully followed up either at home or, in the event of early death, in hospital. FINDINGS: The neonatal mortality rate (NMR) for these infants was 133 per 1000 live births (95% confidence interval: 110-159). The corresponding NMRs (and confidence intervals) for early and late neonates were 112 (91-136) and 21 (12-33) per thousand live births, respectively. The NMR for infants born after fewer than 32 weeks of gestation was 769 (563-910); and was 780 (640-885) for infants whose birth weights were under 1500 g. Eighty-four per cent of neonatal deaths occurred in the first seven days; half within 48 hours. Preterm delivery was implicated in three-quarters of neonatal deaths, but was associated with only one-third of LBW neonates. CONCLUSION: Policy-relevant findings were: that LBW approximately doubles the NMR in a periurban setting in Bangladesh; that neonatal mortality tends to occur early; and that preterm delivery is the most important contributor to the NMR. The group of infants most likely to benefit from improvements in low-cost essential care for the newborn accounted for almost 61% of neonatal mortalities in the cohort. PMID:11477963

    Calf mortality control is vitally important for farmers, not only to improve animal welfare, but also to increase productivity. High calf mortality rates can be related to larger numbers of calves in a herd, employee performance, severe weather, and the neonatal period covering the first 4 weeks of life. Although the basic premise of preventing newborn calf mortality is early detection and treatment of calves at risk for failure of passive transfer of immunoglobulins, calf mortality due to infectious diseases such as acute diarrhea increases in the presence of these physical and psychological stressors. This suggests that farmers should not ignore the effects of secondary environmental factors. For prevention rather than cure, the quality of the environment should be improved, which will improve not only animal welfare but also productivity. This paper presents a review of the literature on newborn calf mortality and discusses its productivity implications. PMID:23384350

    Two recent efforts to quantify the causes of maternal deaths on a global scale generated divergent estimates of abortion-related mortality. Such discrepancies in estimates of abortion-related mortality present an important opportunity to explore unique challenges and opportunities associated with the generation and interpretation of abortion-related mortality estimates. While innovations in primary data collection and estimation methodologies are much needed, at the very least, studies that seek to measure maternal deaths due to abortion should endeavor to improve transparency, acknowledge limitations of data, and contextualize results. As we move towards sustainable development goals beyond 2015, the need for valid and reliable estimates of abortion-related mortality has never been more pressing. The post-MDG development agenda that aims to improve global health, reduce health inequities, and increase accountability, requires new and novel approaches be tested to improve measurement and estimation of abortion-related mortality, as well as incidence, safety and morbidity.

    The level of alcohol consumption in Russia is among the highest in the world and is often associated with a variety of problems in the country. Until recently, however, it was impossible to examine the health and social burdens associated with consumption in Russia due to Soviet secrecy surrounding vital statistics and health data related to alcohol and other topics. This study employed newly available mortality data to describe the demographic, temporal, and spatial patterns of mortality resulting directly from chronic and acute alcohol consumption in the country. The data reveal that in spite of high overall rates of alcohol-related mortality in Russia, levels of mortality vary considerably along these dimensions. Although descriptive in nature, the patterns of alcohol-related mortality in Russia presented here should provide initial observations with which to generate and test hypotheses concerning the causes and consequences of these patterns.

    Background: Unlike the western hemisphere, information about stroke epidemiology in southern Iran is scarce. The aim of this study was to determine the main epidemiological characteristics of patients with stroke and its mortality rate in southern Iran. Methods: A retrospective, single-center, hospital-based longitudinal study was performed at Nemazee Hospital in Shiraz, Southern Iran. Patients with a diagnosis of hemorrhagic and ischemic strokes were identified based on the International Classification of Diseases, 9th and 10th editions, for the period between 2001 and 2010. Demographics including age, sex, area of residence, socioeconomic status, length of hospital stay, and discharge destinations were analyzed in association with mortality. Results: 16351 patients with a mean age of 63.4 years (95% CI: 63.1, 63.6) were included in this analysis. Men were slightly predominant (53.6% vs. 46.4%). Forty-seven percent of the total sample was older than 65,17% were younger than 45, and 2.6% were children younger than 18. The mean hospital stay was 6.3 days (95% CI: 6.2, 6.4). Among all types of strokes, the overall hospital mortality was 20.5%. Multiple logistic regression revealed significantly higher in-hospital mortality in women and children (P<0.001) but not in patients with low socioeconomic status or from rural areas. During the study period, the mortality proportions increased from 17.8% to 22.2%. Conclusion: In comparison to western countries, a larger proportion of our patients were young adults and the mortality rate was higher. PMID:24293785

    Despite the well-established benefits of mineralocorticoid receptor agonists (MRAs) in heart failure with reduced ejection fraction, safety concerns remain in patients with concomitant diabetes mellitus (DM) because of common renal and electrolyte abnormalities in this population. We analyzed all-cause mortality and composite cardiovascular mortality and HF hospitalization over a median 9.9 months among 1,998 patients in the placebo arm of the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study With Tolvaptan (EVEREST) trial by DM status and discharge MRA use. Of the 750 patients with DM, 59.2% were receiving MRAs compared with 62.5% in the non-DM patients. DM patients not receiving MRAs were older, more likely to be men, with an ischemic heart failure etiology and slightly worse renal function compared with those receiving MRAs. After adjustment for baseline risk factors, among DM patients, MRA use was not associated with either mortality (hazard ratio [HR] 0.93; 95% confidence interval [CI] 0.75 to 1.15) or the composite end point (HR 0.94; 95% CI 0.80 to 1.10). Similar findings were seen in non-DM patients (mortality [HR 1.01; 95% CI 0.84 to 1.22] or the composite end point [HR 0.98; 95% CI 0.85 to 1.13] [p >0.43 for DM interaction]). In conclusion, in-hospital initiation of MRA therapy was low (15% to 20%), and overall discharge MRA use was only 60% (with regional variation), regardless of DM status. There does not appear to be clear, clinically significant in-hospital hemodynamic or even renal differences between those on and off MRA. Discharge MRA use was not associated with postdischarge end points in patients hospitalized for worsening heart failure with reduced ejection fraction and co-morbid DM. DM does not appear to influence the effectiveness of MRA therapy. PMID:25060414

    Nowadays, the use of medical sensors with embedded communication modules provides accurate number reading and automatic recording. However, such readers are usually more expensive than similar devices without an embedded communication module. Further, different vendors define proprietary communication protocols and data formats for their own medical sensors. Due to the twin issues of high cost and diversity of standards, the automatic collection of patients' vital signs is not common in hospitals, meaning that medical staff need to periodically collect all patients' vital signs. This may cause further problems in caring for patients. We propose a low-cost reader using a cheap web camera to automatically read vital sign monitors in hospitals. The reader uses a high-resolution web camera to take a series of pictures of vital sign monitors and recognizes vital signs in electronic form and then forwards that information to hospital information systems. Its major benefit is that different sensors equipped with vital sign monitors, whether they include a computer communications module, can be digital-number recognized. It saves time in recording monitored vital signs of patients widely located in hospitals. In sum medical staff care of patients may be usefully assisted by the proposed reader which automatically collects all patients' vital signs, significantly improving patient care. PMID:21607708

    Pancreatic cancer is one of the least common tumors (2.1%), but it remains one of the most lethal. This lethality is primarily due to late stage diagnosis in the vast majority of patients. Here we demonstrate, using a Bayesian network, that we can determine a posteriori, with a high probability of success, the probability of in-hospital death of pancreatic cancer in hospitals across Spain with information related to the type of admission, the type of procedure, the primary diagnosis or the Charlson co-morbidity index. The advantages of using a Bayesian network are that it allows us to examine multiple hypotheses and to measure the effect of the introduction of variables on our hypotheses. Being able to determine deceases in the probability of survival based on hospital admission data, such as the diagnosis resulting in the present admission or the presence of co-morbidities, could facilitate the detection of deficiencies in the patient treatment and improve hospital management. Moreover, the control of related co-morbidities may have an impact on the in-hospital deaths of these patients. PMID:23675228

    This study aims to construct a satisfaction model on nursing service in hospitalized tumor patients. Using questionnaires, data about hospitalized tumor patients' expectation, quality perception and satisfaction of hospital nursing service were obtained. A satisfaction model of nursing service in hospitalized tumor patients was established through empirical study and by structural equation method. This model was suitable for tumor specialized hospital, with reliability and validity. Patient satisfaction was significantly affected by quality perception and patient expectation. Patient satisfaction and patient loyalty was also affected by disease pressure. Hospital brand was positively correlated with patient satisfaction and patient loyalty, negatively correlated with patient complaint. Patient satisfaction was positively correlated with patient loyalty, patient complaints, and quality perception, and negatively correlated with disease pressure and patient expectation. The satisfaction model on nursing service in hospitalized tumor patients fits well. By this model, the quality of hospital nursing care may be improved. PMID:25419410

    The in-hospital spread of automated external defibrillators (AEDs) is aimed to allow for a shock-delivery within three minutes. However, it has to be questioned if the implementation of AED alone really contributes to a 'heart-safe hospital'. We performed a cohort study of 1008 in-hospital emergency calls in a university tertiary care hospital, analysing cardiopulmonary resuscitation (CPR) cases with and without AED use. In total, 484 patients (48%) had cardiac arrest and received CPR. Response time of the emergency team was 4.3 ± 4.0 minutes. Only 8% percent of the CPR cases had a shockable rhythm. In three of 43 placements a shock was delivered by the AED. There were no differences in survival between patients with CPR only and CPR with AED use. Our data do not support the use of an AED for in-hospital CPR if a professional response team is rapidly available. PMID:27246934

  18. [Political crises in Africa and infant and child mortality].

    Many African countries experienced severe political crises after independence, and in a number of cases the crises had significant demographic consequences, especially for child mortality. Data based on maternity histories allowed the reconstruction of child mortality trends over the past 20-30 years in Uganda, Ghana, Rwanda, Madagascar, and Mozambique. The indicator used was the child mortality quotient (number of deaths of under-5 children per 1000 births). Uganda's child mortality declined from 227/1000 in 1960 to 154/1000 in 1970, but the trend was reversed in 1971, when Idi Amin Dada came to power, and the rate reached 204/1000 in 1982 before beginning to decline again. The level of mortality remained high, however, and was still 160/1000 in 1988. Ghana suffered a political and economic crisis during 1979-84. Child mortality rose from 130/1000 in 1978 to 175/1000 in 1983. Mortality rates began a rapid decline after structural adjustment programs were begun, possibly due to improved management of health services. The child mortality rate in Rwanda increased from around 220/1000 in 1960 to 240/1000 in 1975, before beginning a decline in the late 1970s that reached 140/1000 by 1990. The period of political stability and relative prosperity during the 15-year reign of Juvenal Habyarimana was associated with the decline. Political crises marked by student and peasant uprisings were associated with Madagascar's child mortality rate increase from about 145/1000 in 1960 to 185/1000 in 1985. Mozambique was beset by civil war after independence, in which destruction of the health infrastructure was a strategy. The child mortality rate increased from 270/1000 to 470/1000 between 1975 and 1986, a peak war year. The factors by which political crises affect mortality so profoundly remain to be explained, but particular attention should be given to studying the health sector. PMID:12178214

  1. 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. PMID:12284509

    Background Although in-hospital cardiac arrest is common, little is known about readmission patterns and inpatient resource use among survivors of in-hospital cardiac arrest. Methods and Results Within a large national registry, we examined long-term inpatient utilization among 6972 adults ≥65 years who survived an in-hospital cardiac arrest. We examined 30-day and 1-year readmission rates and inpatient costs, overall and by patient demographics, hospital disposition (discharge destination), and neurological status at discharge. The mean age was 75.8 ± 7.0 years, 56% were men, and 12% were black. There were a total of 2005 readmissions during the first 30 days (cumulative incidence rate: 35 readmissions/100 patients [95% CI: 33–37]) and 8751 readmissions at 1 year (cumulative incidence rate: 185 readmissions/100 patients [95% CI: 177–190]). Overall, mean inpatient costs were $7,741 ± $2323 at 30 days and $18,629 ± $9411 at 1 year. Thirty-day inpatient costs were higher in patients of younger age (≥85 years: $6052 [reference]; 75–84 years: $7444 [adjusted cost ratio, 1.23 [1.06–1.42]; 65–74 years: $8291 [adjusted cost ratio, 1.37 [1.19–1.59]; both P<0.001]) and black race (whites: $7413; blacks: $9044; adjusted cost ratio, 1.22 [1.05–1.42]; P<0.001), as well as those discharged with severe neurological disability or to skilled nursing or rehabilitation facilities. These differences in resource use persisted at 1 year and were largely due to higher readmission rates. Conclusion Survivors of in-hospital cardiac arrest have frequent readmissions and high follow-up inpatient costs. Readmissions and inpatient costs were higher in certain subgroups, including patients of younger age and black race. PMID:25351479

    OBJECTIVE: To examine the effect of hospital volume on in-hospital surgical outcomes for knee replacement using six years of Medicare claims data. DATA SOURCES/STUDY SETTING: The data include inpatient claims for a 100 percent sample of Medicare patients who underwent primary knee replacement during 1985-1990. We supplemented these data with information from HCFA's denominator files, the Area Resource File, and the American Hospital Association survey files. STUDY DESIGN: We estimated the probability that a patient has an in-hospital complication in the initial hospitalization for the first primary knee replacement, using a Logit model, for three definitions of complication. The models controlled for hospital volume, other hospital characteristics, patient demographics, and patient health status. We tested for the endogeneity of hospital volume. DATA COLLECTION/EXTRACTION METHODS: A panel of two orthopaedic surgeons and two internists reviewed diagnosis codes to determine whether a complication was likely, possible, or due to anemia. After removing the few observations with bad or missing data, the final population has 295,473 observations. PRINCIPAL FINDINGS: The probability of a likely in-hospital complication declines rapidly from 53 through 107 operations per year, then levels off. Statistical tests imply that hospital volume is exogenous in this patient-level data. Complication rates increased steadily through the study period. Although obesity appeared to lower the probability of a complication, a counterintuitive result, further investigation revealed this to be an artifact of the claims data limit of listing no more than five diagnoses. Controlling for this restriction reversed the effect of obesity. CONCLUSIONS: Rather than uncontrolled expansion of knee surgery to small hospitals, decentralization to regional centers where at least about 50, and preferably about 100, operations per year are assured appears to be the optimal policy to reduce in-hospital

    Height is a marker for health, cognitive ability and economic productivity. Recent research on the determinants of height suggests that postneonatal mortality predicts height because it is a measure of the early life disease environment to which a cohort is exposed. This article advances the literature on the determinants of height by examining the role of early life mortality, including neonatal mortality, in India, a large developing country with a very short population. It uses state level variation in neonatal mortality, postneonatal mortality, and pre-adult mortality to predict the heights of adults born between 1970 and 1983, and neonatal and postneonatal mortality to predict the heights of children born between 1995 and 2005. In contrast to what is found in the literature on developed countries, I find that state level variation in neonatal mortality is a strong predictor of adult and child heights. This may be due to state level variation in, and overall poor levels of, pre-natal nutrition in India. PMID:25499239

    Cryptic, not readily detectable, components of fishing mortality are not routinely accounted for in fisheries management because of a lack of adequate data, and for some components, a lack of accurate estimation methods. Cryptic fishing mortalities can cause adverse ecological effects, are a source of wastage, reduce the sustainability of fishery resources and, when unaccounted for, can cause errors in stock assessments and population models. Sources of cryptic fishing mortality are (1) pre-catch losses, where catch dies from the fishing operation but is not brought onboard when the gear is retrieved, (2) ghost-fishing mortality by fishing gear that was abandoned, lost or discarded, (3) post-release mortality of catch that is retrieved and then released alive but later dies as a result of stress and injury sustained from the fishing interaction, (4) collateral mortalities indirectly caused by various ecological effects of fishing and (5) losses due to synergistic effects of multiple interacting sources of stress and injury from fishing operations, or from cumulative stress and injury caused by repeated sub-lethal interactions with fishing operations. To fill a gap in international guidance on best practices, causes and methods for estimating each component of cryptic fishing mortality are described, and considerations for their effective application are identified. Research priorities to fill gaps in understanding the causes and estimating cryptic mortality are highlighted. PMID:24090548

    Risk-adjusted hospital-wide mortality has been proposed as a key indicator of system-level quality. Several risk-adjusted measures are available, and one-the hospital standardized mortality ratio (HSMR) - is publicly reported in a number of countries, but not in the United States. This paper reviews potential uses of such measures. We conclude that available methods are not suitable for interhospital comparisons or rankings and should not be used for pay-for-performance or value-based purchasing/payment. Hospital-wide mortality is a relatively imprecise, crude measure of quality, but disaggregation into condition- and service-line-specific mortality can facilitate targeted improvement efforts. If tracked over time, both observed and expected mortality rates should be monitored to ensure that apparent improvement is not due to increasing expected mortality, which could reflect changes in case mix or coding. Risk-adjusted mortality can be used as an initial signal that a hospital's mortality rate is significantly higher than statistically expected, prompting further inquiry. PMID:25103495

    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

    This study examines the relationship between self-reported ADHD and adult mortality over a four-year period, and whether ADHD is associated with underlying cause of death (accidents versus all others). If ADHD increases mortality risk through accidents, then interventions may be designed and implemented to reduce risk and prevent premature death. We estimate descriptive statistics and multivariate logistic regression models using data from the 2007 U.S. National Health Interview Survey (NHIS) Sample Adult File linked to National Death Index (NDI) data through 2011 (N=23,352). Analyses are weighted and standard errors are adjusted for the complex sampling design. We find that the odds of dying are significantly higher among those with ADHD than among those without ADHD net of exogenous sociodemographic controls (adjusted odds ratio=1.78, 95% confidence interval=1.01, 3.12). Although marginally non-significant, accidental death is more common among those with ADHD than among those without ADHD (13.2% versus 4.3%, p=0.052). Few population-representative studies examine the relationship between ADHD and adult mortality due to data limitations. Using NHIS data linked to the NDI, we are only able to observe a few deaths among adults with ADHD. However, ADHD is associated with significantly higher odds of dying for adults and results suggest that accidents may be an underlying cause of death more often for decedents with ADHD. Future research should further examine the mechanisms linking ADHD to adult mortality and the extent to which mortality among persons with ADHD is preventable. Regular measurement of ADHD among adults in the NHIS is warranted. PMID:27343403

    Intrinsic and extrinsic mortality are often separated in order to understand and measure aging. Intrinsic mortality is assumed to be a result of aging and to increase over age, whereas extrinsic mortality is assumed to be a result of environmental hazards and be constant over age. However, allegedly intrinsic and extrinsic mortality have an exponentially increasing age pattern in common. Theories of aging assert that a combination of intrinsic and extrinsic stressors underlies the increasing risk of death. Epidemiological and biological data support that the control of intrinsic as well as extrinsic stressors can alleviate the aging process. We argue that aging and death can be better explained by the interaction of intrinsic and extrinsic stressors than by classifying mortality itself as being either intrinsic or extrinsic. Recognition of the tight interaction between intrinsic and extrinsic stressors in the causation of aging leads to the recognition that aging is not inevitable, but malleable through the environment.

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

    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

    Despite numerous previous studies, there is little data on the effects of anesthetics on clinical outcome after off-pump coronary arterial bypass grafting (OPCAB). Therefore, we retrospectively compared the effects of anesthetic choice on in-hospital major adverse events (MAEs) and one-year major adverse cardiovascular and cerebral events (MACCEs) in patients undergoing OPCAB. Electronic medical records were reviewed in 192 patients who received propofol-remifenanil total intravenous anesthesia (TIVA) and propensity score-matched 662 patients who received isoflurane anesthesia. The primary endpoints were in-hospital MAEs and one-year MACCEs. The components of in-hospital MAEs were in-hospital death, myocardial infarction (MI), coronary revascularization, stroke, renal failure, prolonged mechanical ventilation longer than 72 h, and postoperative new cardiac arrhythmia requiring treatment. One-year MACCEs was defined as a composite of all-cause mortality, MI, coronary revascularization, and stroke. There was no significant difference in risk of in-hospital MAEs (OR = 1.29, 95% CI = 0.88–1.88, P = 0.20) or one-year MACCEs (OR = 0.81; 95% CI = 0.46–1.42, P = 0.46) between the groups. The risk of postoperative new arrhythmia including new atrial fibrillation significantly increased in the TIVA group compared to the isoflurane anesthesia group (OR = 1.72, 95% CI = 1.12–2.63, P = 0.01). In conclusion, the choice between propofol-remifentanil TIVA and isoflurane anesthesia did not show differences in incidence of in-hospital MAEs or one-year MACCEs in patients undergoing OPCAB. However, further studies on the effects of anesthetics on development of in-hospital new arrhythmia will be needed. PMID:27054364

    Hyponatremia is the most common electrolyte disorder in hospitalized patients, being associated with increased morbidity and mortality in different clinical conditions. However, the prevalence and impact of this electrolytic disorder in patients hospitalized for an exacerbation of COPD still remains unknown. The aim of the present study was to clarify these points. A total of 424 patients hospitalized due to a COPD exacerbation were consecutively included, showing a frequency of hyponatremia of 15.8% (hyposmolar in most cases). Even though patients with and without hyponatremia showed a similar age, comorbidities, lung function impairment, presence of previous exacerbations, hospitalizations, most of the comorbidities and the overall severity index (APACHE II), their clinical outcomes were worse. Indeed, their hospitalization length, mechanical ventilation requirements and deaths (both during admission and within the months following discharge) were higher than those of non-hyponatremic patients. A sodium threshold lower than 129.7 mEq/L exhibited the better discriminatory power for death prediction. We conclude that hyponatremia (especially if severe) is a predictive marker for a bad clinical course in COPD exacerbations and therefore, patients with this electrolyte abnormality should be carefully monitored.

    Objective We hypothesized that deficiency in 25-hydroxy vitamin D at critical care initiation would be associated with all cause mortality. Design Two-center observational study. Setting Two teaching hospitals in Boston, Massachusetts Patients 1,325 patients, age ≥ 18 years, in whom 25-hydroxy vitamin D was measured 7 days prior to or after critical care initiation between 1998 and 2009. Measurements 25-hydroxy vitamin D was categorized as deficiency in 25-hydroxy vitamin D (≤15 ng/mL), insufficiency (16–29 ng/mL) and sufficiency (≥30 ng/mL). Logistic regression examined death by days 30, 90 and 365 post-critical care initiation and in hospital mortality. Adjusted odds ratios were estimated by multivariable logistic regression models. Interventions None Key Results 25-hydroxy vitamin D deficiency is predictive for short term and long term mortality. 30 days following critical care initiation, patients with 25-hydroxy vitamin D deficiency have an OR for mortality of 1.85 (95% CI, 1.15–2.98;P=0.01) relative to patients with 25-hydroxy vitamin D sufficiency. 25-hydroxy vitamin D deficiency remains a significant predictor of mortality at 30 days following critical care initiation following multivariable adjustment for age, gender, race, Deyo-Charlson index, sepsis, season, and surgical versus medical patient type (adjusted OR 1.94; 95% CI, 1.18–3.20;P=0.01). Results were similarly significant at 90 and 365 days following critical care initiation and for in hospital mortality. The association between vitamin D and mortality was not modified by sepsis, race, or Neighborhood poverty rate, a proxy for socioeconomic status. Conclusion Deficiency of 25-hydroxy vitamin D at the time of critical care initiation is a significant predictor of all cause patient mortality in a critically ill patient population. PMID:21926604

    Purpose Congenital diaphragmatic hernia (CDH) is associated with significant in-hospital mortality, morbidity and length-of-stay (LOS). We hypothesized that the degree of pulmonary support on hospital day-30 may predict in-hospital mortality, LOS, and discharge oxygen needs and could be useful for risk prediction and counseling. Methods 862 patients in the CDH Study Group registry with a LOS≥30 days were analyzed (2007–2010). Pulmonary support was defined as (1) room-air (n=320) (2) noninvasive supplementation (n=244) (3) mechanical ventilation (n=279) and (4) extracorporeal membrane oxygenation (ECMO, n=19). Cox Proportional hazards and logistic regression models were used to determine the case-mix adjusted association of oxygen requirements on day-30 with mortality and oxygen requirements at discharge. Results On multivariate analysis, use of ventilator (HR 5.1, p=.003) or ECMO (HR 19.6, p<.001) were significant predictors of in-patient mortality. Need for non-invasive supplementation or ventilator on day-30 was associated with a respective 22-fold (p<.001) and 43-fold (p<.001) increased odds of oxygen use at discharge compared to those on room-air. Conclusions Pulmonary support on Day-30 is a strong predictor of length of stay, oxygen requirements at discharge and in-patient mortality and may be used as a simple prognostic indicator for family counseling, discharge planning, and identification of high-risk infants.

    Elderly trauma patients have worse outcomes than their younger counterparts. Early risk stratification remains difficult, particularly because traditional vital signs are less reliable. We hypothesized that arrival lactate and base deficit (BD) could be used to predict mortality in elderly trauma patients with a normal admission blood pressure. We retrospectively evaluated the prospectively collected trauma registry at our urban Level I trauma center between 2003 and 2009. Patients sustaining blunt trauma, age 55 years or older, with a systolic blood pressure 90 mmHg or higher, and who had arterial lactate and/or BD measured within 4 hours of arrival comprised the study group. Primary outcomes were in-hospital and 24-hour mortality. There were 364 patients with a lactate and 324 with a BD drawn. Patients with a lactate 2.5 mmol or greater were 3.7 times more likely to die than those with a lactate less than 2.5 mmol (95% CI, 1.6 to 8.2; P = 0.0018). The OR for mortality was 5.2 (95% CI, 2.5 to 11.2; P < 0.0001) in patients with a BD -4 or less. Elevated lactate and BD were even stronger predictors of early mortality (within first 24 hours). After increasing the hypotension threshold to a systolic blood pressure 110 mmHg or greater, lactate and BD remained highly predictive of in-hospital and 24-hour mortality. PMID:22127083

    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

    Background: Coronary artery disease (CAD) is accountable for more than 30% of deaths worldwide and is, thus, deemed the most important factor in terms of disease burden around the globe. This study aimed to evaluate CAD and its risk factors in hospitalized patients in the East Azerbaijan Province, northwest Iran, from 2006 to 2007. Methods: Data on 18.323 patients hospitalized due to cardiovascular diseases were collected to evaluate the diseases and their risk factors in 15 hospitals in the East Azerbaijan Province, northwest Iran. We assessed the main diagnosis of cardiovascular disease on admission in each hospital. Also, types of interventional and surgical procedures were assessed and all these variables were compared between men and women. Results: The study population consisted of 56.6% male and 43.4% female patients. The median and range between quartile 1 and 3 (Q1–Q3) ages of the males and females were 59 (49–70) and 62 (51–71) years, respectively. Ischemic heart diseases were diagnosed in 68.4%, electrophysiological disorders in 6.5%, and valvular heart diseases in 4.5% of the patients. The frequencies of the studied risk factors were as follows: cigarette smoking (47.5%); hypertension (66.95%); diabetes mellitus (35.9%); and history of cerebrovascular accident (16.4%) and renal disease (13.4%). Medical therapy was performed in 79.23%, surgery in 6.28%, and cardiovascular interventional therapy in 13.99% of the patients. The in-hospital mortality rate was 1.57% (1.42% in the males and 1.76% in the females; p value = 0.009). Conclusion: The most frequent known risk factors in the hospitalized patients were smoking, alcohol consumption, and diabetes. In the northwest of Iran, age at hospitalization due to cardiovascular diseases is slightly lower than that in the Western populations; however, sex distribution, diagnoses, and treatment modalities are not significantly different from those reported in Western countries.

    Between 2.2% and 17% of all strokes have symptom onset during hospitalization in a patient originally admitted for another diagnosis or procedure. A response system to rapidly evaluate inpatients with acute neurologic symptoms facilitates evaluation and treatment of stroke developing during hospitalization. The National Stroke Association implemented an in-hospital stroke quality-improvement initiative from July 2010 to June 2011 in 6 certified stroke centers from Michigan, South Carolina, Pennsylvania, Colorado, Washington, and North Carolina. Three hundred ninety-three in-hospital stroke alerts were examined over a 1-year period. Of the alerts, 42.5% were for ischemic stroke, 8.7% probable or possible TIA, 2.8% intracranial hemorrhage, and 46.1% were stroke mimics. The most common stroke mimics were seizure, hypotension, and delirium. Participating hospitals had an alarm rate for diagnoses other than acute cerebrovascular events ranging from 28.0% to 66.7%. Of 194 in-hospital stroke/transient ischemic attack cases, 8.2% received intravenous thrombolysis alone, 10.3% received intra-arterial/mechanical thrombolysis alone, and 1% received both. No patient with a stroke mimic received thrombolysis. Our findings suggest that in-hospital response teams need to be prepared to respond to a range of acute medical conditions other than ischemic stroke. PMID:25537887

    Between 1989 and 1991 two related research projects were undertaken by the authors at the Department of Information and Library Studies, Aberystwyth, into services for children in hospital. This article summarizes the findings of the first of the projects, a survey of book and library services to children in hospital, giving a national profile of provision. It demonstrates a substantial provision of reading and other materials available to children in hospital but a small number of library services, as such. Nurses, teachers and hospital play staff generally exploited these materials for pleasure, educational and therapeutic purposes. The survey was based on questionnaires sent to all hospitals in the UK which treated children and was addressed, where possible, to hospital librarians, otherwise to the senior paediatric nurse. A shorter questionnaire was also addressed to all local authority Young People's and Schools Library services for a public library or school library perspective. Where there was evidence of the use of reading therapy, a further questionnaire was sent to explore its practice. A second article will discuss the results of the second project, which was devoted to a further exploration of reading therapy with children in hospital. PMID:10120028

    Because few randomized trials have been done, little is known about appropriate glycemic control in hospitalized patients with chronic kidney disease (CKD) and diabetes mellitus. These patients are at high risk of hypoglycemia. It is prudent to monitor glucose closely, set less-stringent blood sugar goals, avoid oral antidiabetic agents, and possibly reduce insulin dosage.

    This mixed-methods study addressed the problem that although waiting placement is considered a major hospital utilization issue, minimal evidence exists to highlight the extent of it and the personal impact of waiting placement. An analysis of two years of complete hospital data for the Canadian province of Alberta was undertaken to examine waiting placement rates and describe waiting placement patients. Qualitative interviews and observations of elderly patients waiting in hospital for nursing home placement were also undertaken to gain an understanding of the lived experience of waiting for placement in hospital. Only 1.8% of all inpatients were waiting placement with an ALC (Alternative Level of Care) designation, 80% of ALC waits were less than 41 days (mean=29.85, median=14), and 2.2% of total hospital bed days in these two years were used by ALC patients. Three qualitative themes emerged: (a) coming to a realization of this significant move, (b) waiting is boring and distressing, and (c) hospitals are not designed for waiting placement. The findings of this study should raise awareness that although relatively few people wait placement in hospital, there are some major possible negative effects of waiting for placement in hospital for those who wait; with remedies to address waiting placement care deficits needed.

    To assess Indias recent trends in child mortality rates and disparities and identify ways to reduce child mortality and wealth-related health disparities, we analyzed three years of data from Indias National Family Health Survey related to child mortality. Nationally, declines in average child mortality were statistically significant, but declines in inequality were not. Urban areas had lower child mortality rates than rural areas but higher inequalities. Interstate differences in child mortality rates were significant, with rates in the highest-mortality states four to six times higher than in the lowest-mortality states. However, child mortality in most states declined. PMID:23396786

    A retrospective cohort mortality study was conducted among a cohort of 1,261 white males employed one or more months in chrysotile asbestos textile operations and followed between 1940 and 1975. Statistically significant excess mortality was observed for all causes combined (standardized mortality ratio (SMR) . 150), lung cancer (SMR . 135), diseases of the circulatory system (SMR . 125), nonmalignant respiratory diseases (SMR . 294), and accidents (SMR . 134). Using estimated fiber exposure levels in conjunction with detailed worker job histories, exposure-response relationships were investigated. Strong exposure-response relationships for lung cancer and asbestos related non-malignant respiratory diseases were observed. Compared with data for chrysotile miners and millers, chrysotile textile workers were found to experience significantly greater lung cancer mortality at lower lifetime cumulative exposure levels. Factors such as differences in airborne fiber characteristics may partially account for the large differences in exposure response between textile workers and miners and millers.

    OBJECTIVE: Hip fractures have been associated with increased mortality in the elderly. Several risk factors such as the time between the insult and the surgical repair have been associated with hip fracture mortality. Nevertheless, the risk of delayed surgical repair remains controversial. Few studies have examined this issue in Brazil. The aim of this study was to study the risk factors for death one year after hip fracture and in-hospital stay at a tertiary hospital in South Brazil. METHODS: A prospective cohort study was carried out from April 2005 to April 2011 at a tertiary university hospital at Santa Maria, Brazil. Subjects admitted for hip fracture who were 65 years of age or older were followed for one year. Information about fracture type, age, gender, clinical comorbidities, time to surgery, discharge, and American Society of Anesthesiologists score were recorded. Death was evaluated during the hospital stay and at one year. RESULTS: Four hundred and eighteen subjects were included in the final analysis. Of these, 4.3% died in-hospital and 15.3% were dead at one year. Time to surgery, American Society of Anesthesiologists score, Ischemic Heart Disease, and in-hospital stay were associated with death at one year in the univariate analysis. The American Society of Anesthesiologists score and time to surgery were one-year mortality predictors in the final regression model. In-hospital death was associated with American Society of Anesthesiologists score and age. CONCLUSION: Time to surgery is worryingly high at the South Brazil tertiary public health center studied here. Surgical delay is a risk factor that has the potential to be modified to improve mortality. PMID:24714833

    Objective. Out of hospital cardiac arrest (OHCA) patients are a critically ill patient population with high mortality. Combining mild therapeutic hypothermia (MTH) with early coronary intervention may improve outcomes in this population. The aim of this study was to evaluate predictors of mortality in OHCA patients undergoing MTH with and without cardiac catheterization. Design. A retrospective cohort of OHCA patients who underwent MTH with catheterization (MTH + C) and without catheterization (MTH + NC) between 2006 and 2011 was analyzed at a single tertiary care centre. Predictors of in-hospital mortality and neurologic outcome were determined. Results. The study population included 176 patients who underwent MTH for OHCA. A total of 66 patients underwent cardiac catheterization (MTH + C) and 110 patients did not undergo cardiac catheterization (MTH + NC). Immediate bystander CPR occurred in approximately half of the total population. In the MTH + C and MTH + NC groups, the in-hospital mortality was 48% and 78%, respectively. The only independent predictor of in-hospital mortality for patients with MTH + C, after multivariate analysis, was baseline renal insufficiency (OR = 8.2, 95% CI 1.8–47.1, and p = 0.009). Conclusion. Despite early cardiac catheterization, renal insufficiency and the absence of immediate CPR are potent predictors of death and poor neurologic outcome in patients with OHCA.

    Mortality among people with developmental disabilities was reviewed using recent data obtained from the California Department of Developmental Services. The time interval for this report was 1991-1995. We defined two study cohorts: one beginning in January 1991 and a second in April 1993. The latter period represented the years of implementation of the Coffelt settlement. Our primary interest was in the Coffelt period cohort. Statistically significant association with increased rates of mortality was found for community residence. A trend of declining mortality was noted for the community facilities from 1991-1995, but not for the developmental centers. PMID:9803127

    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.

    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

    We studied the association of daily mortality with short-term variations in the ambient concentrations of major gaseous pollutants and PM in the Netherlands. The magnitude of the association in the four major urban areas was compared with that in the remainder of the country. Daily cause-specific mortality counts, air quality, temperature, relative humidity, and influenza data were obtained from 1986 to 1994. The relationship between daily mortality and air pollution was modeled using Poisson regression analysis. We adjusted for potential confounding due to long-term and seasonal trends, influenza epidemics, ambient temperature and relative humidity, day of the week, and holidays, using generalized additive models. Influenza episodes were associated with increased mortality up to 3 weeks later. Daily mortality was significantly associated with the concentration of all air pollutants. An increase in the PM10 concentration by 100 micrograms/m3 was associated with a relative risk (RR) of 1.02 for total mortality. The largest RRs were found for pneumonia deaths. Ozone had the most consistent, independent association with mortality. Particulate air pollution (e.g., PM10, black smoke [BS]) was not more consistently associated with mortality than were the gaseous pollutants SO2 and NO2. Aerosol SO4(-2), NO3-, and BS were more consistently associated with total mortality than was PM10. The RRs for all pollutants were substantially larger in the summer months than in the winter months. The RR of total mortality for PM10 was 1.10 for the summer and 1.03 for the winter. There was no consistent difference between RRs in the four major urban areas and the more rural areas. PMID:11002600

    Natural language processing tools allow the characterization of sentiment–that is, terms expressing positive and negative emotion–in text. Applying such tools to electronic health records may provide insight into meaningful patient or clinician features not captured in coded data alone. We performed sentiment analysis on 2,484 hospital discharge notes for 2,010 individuals from a psychiatric inpatient unit, as well as 20,859 hospital discharges for 15,011 individuals from general medical units, in a large New England health system between January 2011 and 2014. The primary measures of sentiment captured intensity of subjective positive or negative sentiment expressed in the discharge notes. Mean scores were contrasted between sociodemographic and clinical groups in mixed effects regression models. Discharge note sentiment was then examined for association with risk for readmission in Cox regression models. Discharge notes for individuals with greater medical comorbidity were modestly but significantly lower in positive sentiment among both psychiatric and general medical cohorts (p<0.001 in each). Greater positive sentiment at discharge was associated with significantly decreased risk of hospital readmission in each cohort (~12% decrease per standard deviation above the mean). Automated characterization of discharge notes in terms of sentiment identifies differences between sociodemographic groups, as well as in clinical outcomes, and is not explained by differences in diagnosis. Clinician sentiment merits investigation to understand why and how it reflects or impacts outcomes. PMID:26302085

    Introduction Staphylococcus aureus bacteremia is associated with significant morbidity and mortality. Given the paucity of recent Canadian data, we estimated the mortality rate associated with S. aureus bacteremia in a tertiary care hospital and identified risk factors associated with mortality. Methods We retrospectively reviewed the records of adults with S. aureus bacteremia admitted to a tertiary care centre in southwestern Ontario between 2008 and 2012. Cox regression analysis was used to evaluate associations between predictor variables and all-cause, in-hospital, and 90-day postdischarge mortality. Results Of the 925 patients involved in the study, 196 (21.2%) died in hospital and 62 (6.7%) died within 90 days after discharge. Risk factors associated with in-hospital and all-cause mortality included age, sepsis (adjusted hazard ratio [adjusted HR] 1.49, 95% confidence interval [CI] 1.08–2.06, p = 0.02), admission to the intensive care unit (adjusted HR 3.78, 95% CI 2.85–5.02, p < 0.0001), hepatic failure (adjusted HR 3.36, 95% CI 1.91–5.90, p < 0.0001) and metastatic cancer (adjusted HR 2.58, 95% CI 1.77–3.75, p < 0.0001). Methicillin resistance, hepatic failure, cerebrovascular disease, chronic obstructive pulmonary disease and metastatic cancer were associated with postdischarge mortality. Interpretation The all-cause mortality rate in our cohort was 27.9%. Identification of predictors of mortality may guide empiric therapy and provide prognostic clarity for patients with S. aureus bacteremia. PMID:25553328

    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.

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

    Background Acute coronary syndrome (ACS) is one of the main causes of morbidity and mortality in the modern world. A sedentary lifestyle, present in 85% of the Brazilian population, is considered a risk factor for the development of coronary artery disease. However, the correlation of a sedentary lifestyle with cardiovascular events (CVE) during hospitalization for ACS is not well established. Objective To evaluate the association between physical activity level, assessed with the International Physical Activity Questionnaire (IPAQ), with in-hospital prognosis in patients with ACS. Methods Observational, cross-sectional, and analytical study with 215 subjects with a diagnosis of ACS consecutively admitted to a referral hospital for cardiac patients between July 2009 and February 2011. All volunteers answered the short version of the IPAQ and were observed for the occurrence of CVE during hospitalization with a standardized assessment conducted by the researcher and corroborated by data from medical records. Results The patients were admitted with diagnoses of unstable angina (34.4%), acute myocardial infarction (AMI) without ST elevation (41.4%), and AMI with ST elevation (24.2%). According to the level of physical activity, the patients were classified as non-active (56.3%) and active (43.7%). A CVE occurred in 35.3% of the cohort. The occurrence of in-hospital complications was associated with the length of hospital stay (odds ratio [OR] = 1.15) and physical inactivity (OR = 2.54), and was independent of age, systolic blood pressure, and prior congestive heart failure. Conclusion A physically active lifestyle reduces the risk of CVE
