Project description:By exploiting data from the Toxic Release Inventory of the United States, we have established that the toxicological footprint (TF) increased by 3.3% (88.4 Mt) between 1998 and 1999 and decreased by 39% (1088.5 Mt) between 1999 and 2013. From 1999 to 2006, the decreasing TF was driven by improvements in emissions intensity (i.e. gains in production efficiency) through toxic chemical management options: cleaner production; end of pipe treatment; transfer for further waste management; and production scale. In particular, the mining sector reduced its TF through outsourcing processes. Between 2006 and 2009, decreasing TF was due to decrease in consumption volume triggered by economic recession. Since 2009, the economic recovery increased TF, overwhelming the influence of improved emissions intensity through population growth, consumption and production structures. Accordingly, attaining a less-toxic economy and environment will be influenced by a combination of gains in production efficiency through improvement in emissions mitigation technologies and changes in consumption patterns. Overall, the current analysis highlights the structural dynamics of toxic chemical release and would inform future formulation of effective mitigation standards and management protocols towards the detoxification of the environment.

Project description:BackgroundPediatric differentiated thyroid cancer (DTC) rates have increased over time in the United States and worldwide. Improvements in imaging for the diagnosis of DTC have been hypothesized as a potential driver of these increases. This study stratifies temporal trends in pediatric DTC by stage and tumor size to assess whether rates of large, late-stage cancers, which are likely to be clinically meaningful, are increasing over time.MethodsAge-standardized incidence rates (ASRs) of DTC and annual percent changes (APCs) in primary DTC rates were estimated for 0- to 19-year-olds with data from 39 US cancer registries during 1998-2013.ResultsDuring 1998-2013, 7296 cases of DTC were diagnosed (6652 papillary cases and 644 follicular cases). APCs of pediatric DTCs significantly increased by 4.43%/y [95% CI, 3.74%/y-5.13%/y], primarily because of increases in papillary histologies. Increasing trends were observed for children aged 10 to 19 years for both sexes and for non-Hispanic whites, non-Hispanic blacks, and Hispanics. Rates increased significantly over the time period for all tumor stages (APClocalized , +4.06%/y [95% CI, 2.84%/y-5.29%/y]; APCregional , +5.68%/y [95% CI, 4.64%/y-6.73%/y]; APCdistant , +8.55%/y [95% CI, 5.03%/y-12.19%/y]) and across tumor sizes (APC<1 cm , +9.46%/y [95% CI, 6.13%/y-12.90%/y]; APC1-2 cm , +6.92%/y [95% CI, 4.31%/y-9.60%/y]; APC>2 cm , +4.69%/y [95% CI, 2.75%/y-6.67%/y]).ConclusionsSignificantly increasing rates of DTC over time among 10- to 19-year-olds in the United States are unlikely to be entirely explained by increases in medical surveillance during childhood because rates of large and late-stage DTC are increasing over time. Future studies should examine environmental and other factors that may be contributing to rising DTC rates.

Project description:ImportanceProphylaxis and treatment guidelines for infective endocarditis have changed substantially over the past decade. In the United States, few population-based studies have explored the contemporary epidemiology and outcomes of endocarditis.ObjectiveTo quantify trends in the incidence and etiologies of infective endocarditis in the United States.Design, setting, and participantsRetrospective population epidemiology study of patients hospitalized with a first episode of endocarditis identified from mandatory state databases in California and New York State between January 1, 1998, and December 31, 2013.ExposureInfective endocarditis.Main outcomes and measuresOutcomes were crude and standardized incidence of endocarditis and trends in patient characteristics and disease etiology. Trends in acquisition mode, organism, and mortality were analyzed.ResultsAmong 75 829 patients with first episodes of endocarditis (mean [SD] age, 62.3 [18.9] years; 59.1% male), the standardized annual incidence was stable between 7.6 (95% CI, 7.4 to 7.9) and 7.8 (95% CI, 7.6 to 8.0) cases per 100 000 persons (annual percentage change [APC], -0.06%; 95% CI, -0.3% to 0.2%; P = .59). From 1998 through 2013, the proportion of patients with native-valve endocarditis decreased (from 74.5% to 68.4%; APC, -0.7%; 95% CI, -0.9% to -0.5%; P < .001). Prosthetic-valve endocarditis increased (from 12.0% to 13.8%; APC, 1.3%; 95% CI, 0.8% to 1.7%; P < .001), and cardiac device-related endocarditis increased (from 1.3% to 4.1%; APC, 8.8%; 95% CI, 7.8% to 9.9%; P < .001). The proportion of patients with health care-associated nosocomial endocarditis decreased (from 17.7% to 15.3%; APC, -1.0%; 95% CI, -1.4% to -0.7%; P < .001). The proportion of patients with health care-associated nonnosocomial endocarditis increased (from 32.1% to 35.9%; APC, 0.8%; 95% CI, 0.5% to 1.1%; P < .001). The incidence of oral streptococcal endocarditis did not increase (unadjusted: APC, -0.1%; 95% CI, -0.8% to 0.6%; P = .77; adjusted: APC, -1.3%; 95% CI, -1.8% to -0.7%; P < .001). Crude 90-day mortality was unchanged (from 23.9% to 24.2%; APC, -0.3%; 95% CI, -1.0% to 0.4%; P = .44); adjusted risk of 90-day mortality decreased (adjusted hazard ratio per year, 0.982; 95% CI, 0.978 to 0.986; P < .001).Conclusions and relevanceIn California and New York State, the overall standardized incidence of infective endocarditis was stable from 1998 through 2013, with changes in patient characteristics and etiology over this time.

Project description:BACKGROUND: No study has been carried out on the time trend in the prevalence of chronic bronchitis (CB) in recent years, despite its clinical and epidemiological relevance. We evaluated the trend in CB prevalence during the past decade among young Italian adults. METHODS: A screening questionnaire was mailed to general population samples of 20-44 year-old subjects in two cross-sectional surveys: the Italian Study on Asthma in Young Adults (ISAYA) (1998/2000; n = 18,873, 9 centres) and the screening stage of the Gene Environment Interactions in Respiratory Diseases (GEIRD) study (2007/2010; n = 10,494, 7 centres). CB was defined as having cough and phlegm on most days for a minimum of 3 months a year and for at least 2 successive years. The prevalence rates and the risk ratios (RRs) for the association between CB and each potential predictor were adjusted for gender, age, season of response, type of contact, cumulative response rate, and centre. RESULTS: CB prevalence was 12.5% (95% CI: 12.1-12.9%) in 1998/2000 and 12.6% (95% CI: 11.7-13.7%) in 2007/2010; it increased among never smokers (from 7.6 to 9.1%, p = 0.003), current light smokers (<15 pack-years; from 15.1 to 18.6%, p < 0.001), and unemployed/retired subjects (from 14.3 to 19.1%, p = 0.001). In this decade, the prevalence of current smoking decreased (from 33.6 to 26.9%, p < 0.001), whereas the prevalence of unemployment/premature retirement (from 5.3 to 6.0%, p = 0.005), asthma (from 5.0 to 6.2%, p = 0.003), and allergic rhinitis (from 19.5 to 24.5%, p < 0.001) increased. In both 1998/2000 and 2007/2010, the likelihood of having CB was significantly higher for women, current smokers, asthmatic patients, and subjects with allergic rhinitis. During this period, the strength of the association between CB and current heavy smoking (?15 pack-years) decreased (RR: from 4.82 to 3.57, p = 0.018), whereas it increased for unemployment/premature retirement (from 1.11 to 1.53, p = 0.019); no change was observed for gender, asthma, and allergic rhinitis. CONCLUSIONS: Despite the significant reduction in current smoking, CB prevalence did not vary among young Italian adults. The temporal pattern of CB prevalence can only be partly explained by the increase of unemployment/premature retirement, asthma and allergic rhinitis, and suggests that other factors could have played a role.

Project description:BACKGROUND:Brain and other central nervous system (CNS) cancers are the leading cause of U.S. pediatric cancer mortality. Incidence trends can provide etiologic insight. We report trends in incidence rates of pediatric malignant CNS cancers and pilocytic astrocytoma (nonmalignant but historically registered) in the United States. METHODS:Age-standardized incidence rates and annual percent changes (APC) in rates during 1998 to 2013 were calculated for children aged 0 to 19, stratified by subtype, age, sex, and for gliomas, histology and location. We estimated the absolute change in number of cases diagnosed U.S.-wide during 2013 compared with the expected number of cases had 1998 rates remained stable. RESULTS:Rates of all pediatric malignant CNS cancer combined (n = 18,612) did not change [APC: 0.16; 95% confidence interval (CI): -0.21-0.53]. There were statistically significant changes in several subtypes; however, glioma incidence (n = 10,664) increased by 0.77% per year (95% CI: 0.29-1.26), embryonal cancer rates (n = 5,423) decreased by 0.88% per year (95% CI: -1.33 to -0.43), and pilocytic astrocytoma rates (n = 6,858) increased by 0.89% per year (95% CI: 0.21-1.58). Of the 1,171 malignant tumors and 450 pilocytic astrocytomas diagnosed in U.S. children in 2013, we estimated 120 excess gliomas, 94 excess pilocytic astrocytomas, and 72 fewer embryonal CNS tumors than would be expected had 1998 rates remained stable. CONCLUSIONS:The gradual changes in incidence we observed for specific types of pediatric CNS cancers are likely due to a combination of changes in classification and diagnosis and true changes in CNS cancer. IMPACT:Continued surveillance of pediatric CNS tumors should remain a priority, given their significant contribution to pediatric cancer-related deaths.

Project description:Patterns of waterpipe smoking and associated other tobacco use were assessed among U.S. young adults (aged 18-24 years).A descriptive analysis of baseline data (2013-2014) from the Population Assessment of Tobacco and Health Study was conducted in 2016.The study included 9,119 young adults-44% ever and 11% past-30 day waterpipe smokers (12% of men and 9% of women were past-30 day smokers). Among past-30 day smokers, waterpipe smoking frequency was distributed as follows: 4% daily, 23% weekly, 36% monthly, and 37% less than monthly. The average session exceeded 30 minutes for 79% of respondents. In this age group, 29% were exclusive waterpipe smokers, 16% were dual (waterpipe/cigarette) smokers, 8% were dual (waterpipe/e-cigarette) users, 19% were waterpipe/cigarette/e-cigarette users, and 28% presented with other combinations of poly use.Waterpipe smoking is widespread among U.S. young adults. Although waterpipe patterns are predominantly intermittent, the average smoking session provides prolonged exposure. Waterpipe smoking among young adults is primarily characterized by the use of flavored tobacco, the café culture, and poly tobacco use. Rising trends in waterpipe smoking among U.S. youth warrant a strong regulatory response to prevent future waterpipe-related morbidity and mortality.

Project description:BackgroundChronic non-communicable diseases (NCDs) are the leading cause of multimorbidity. Access to effective and equitable health services that meet NCDs' needs is still limited in many countries. This constitutes the main barrier to coping with NCDs, especially in minimising the suffering of those who are already sick. The present study aimed to identify the relationship between multimorbidity and the use of different health services in Brazil from 1998 to 2013.MethodsThis is a panel study using data from the health supplement of the National Household Sample Survey of 1998, 2003 and 2008 and data from the National Health Survey carried out in 2013. Three health service utilization outcomes were considered: 1. search for health services in the last 15 days (excluding dental services), 2. medical consultation in the previous 12 months and 3. hospitalisations over the last 12 months. Multimorbidity was assessed by counting the number of morbidities from a list of 10 morbidities. Poisson regression models stratified by sex were used to estimate the crude and adjusted prevalence ratios and their respective 95% confidence intervals for each outcome of health service use and multimorbidity, per year.ResultsThere was an increase in the prevalence of demand for health services and medical consultations in the last 12 months between 1998 and 2013, regardless of the multimorbidity classification. The prevalence of hospitalisations has decreased over the study period and increased twofold in individuals with multimorbidity. Having multimorbidity increased the use of health services for the three outcomes under the study, being more expressive among men.ConclusionsThis study found that individuals with multimorbidity have higher levels of use of health services. Better understand the multimorbidity epidemiology and the associated impacts on the use and costs of health services can increase the quality of care provided to these patients and reduce rising health care costs.

Project description:BACKGROUND:Acute liver failure (ALF) is a rare syndrome of severe, rapid-onset hepatic dysfunction-without prior advanced liver disease-that is associated with high morbidity and mortality. Intensive care and liver transplantation provide support and rescue, respectively. OBJECTIVE:To determine whether changes in causes, disease severity, treatment, or 21-day outcomes have occurred in recent years among adult patients with ALF referred to U.S. tertiary care centers. DESIGN:Prospective observational cohort study. (ClinicalTrials .gov: NCT00518440). SETTING:31 liver disease and transplant centers in the United States. PATIENTS:Consecutively enrolled patients-without prior advanced liver disease-with ALF (n = 2070). MEASUREMENTS:Clinical features, treatment, and 21-day outcomes were compared over time annually for trends and were also stratified into two 8-year periods (1998 to 2005 and 2006 to 2013). RESULTS:Overall clinical characteristics, disease severity, and distribution of causes remained similar throughout the study period. The 21-day survival rates increased between the two 8-year periods (overall, 67.1% vs. 75.3%; transplant-free survival [TFS], 45.1% vs. 56.2%; posttransplantation survival, 88.3% vs. 96.3% [P < 0.010 for each]). Reductions in red blood cell infusions (44.3% vs. 27.6%), plasma infusions (65.2% vs. 47.1%), mechanical ventilation (65.7% vs. 56.1%), and vasopressors (34.9% vs. 27.8%) were observed, as well as increased use of N-acetylcysteine (48.9% vs. 69.3% overall; 15.8% vs. 49.4% [P < 0.001] in patients with ALF not due to acetaminophen toxicity). When examined longitudinally, overall survival and TFS increased throughout the 16-year period. LIMITATIONS:The duration of enrollment, the number of patients enrolled, and possibly the approaches to care varied among participating sites. The results may not be generalizable beyond such specialized centers. CONCLUSION:Although characteristics and severity of ALF changed little over 16 years, overall survival and TFS improved significantly. The effects of specific changes in intensive care practice on survival warrant further study. PRIMARY FUNDING SOURCE:National Institutes of Health.

Project description:The voting behaviors of elected officials shape the public's health. Little is known, however, about the characteristics of elected officials who vote in concordance with public health policy recommendations. This article presents the results of study conducted with the aims of: 1) testing the hypothesis that US Democrat Senators vote in concordance with American Public Health Association (APHA) policy recommendations more frequently than US Republican Senators, 2) identifying US Senator characteristics independently associated with voting in concordance with APHA, and 3) assessing trends in APHA voting concordance by political party.We created a legislative dataset of 1434 votes cast on 111 legislative proposals by 184 US Senators during the years 1998 through 2013. Mixed effects linear regression models were used to estimate the independent contributions of political party, gender, geographic region, and year effects to annual APHA voting concordance. Votes were nested within Senators who were nested within States to account for non-independence and models considered potential for time and spatial patterns in the data.Adjusting for covariates and accounting for serial and spatial autocorrelation, Democrats averaged 59.1 percentage points higher in annual APHA voting concordance than Republicans (95% CI: 55.5, 62.7), females averaged 7.1 percentage points higher than males (95% CI: 1.9, 12.3), and Northeastern Senators averaged 16.1 percentage points higher than Southern Senators (95% CI: 9.1, 23.1).Elected official's political party affiliation, gender, and geographic region are independently associated with public health voting decisions and should be considered when targeting and tailoring science-based policy dissemination strategies.

Project description:The US Food Safety Modernization Act (FSMA) gives food safety regulators increased authority to require implementation of safety measures to reduce the contamination of produce. To evaluate the future impact of FSMA on food safety, a better understanding is needed regarding outbreaks attributed to the consumption of raw produce. Data reported to the US Centers for Disease Control and Prevention's Foodborne Disease Outbreak Surveillance System during 1998-2013 were analysed. During 1998-2013, there were 972 raw produce outbreaks reported resulting in 34 674 outbreak-associated illnesses, 2315 hospitalisations, and 72 deaths. Overall, the total number of foodborne outbreaks reported decreased by 38% during the study period and the number of raw produce outbreaks decreased 19% during the same period; however, the percentage of outbreaks attributed to raw produce among outbreaks with a food reported increased from 8% during 1998-2001 to 16% during 2010-2013. Raw produce outbreaks were most commonly attributed to vegetable row crops (38% of outbreaks), fruits (35%) and seeded vegetables (11%). The most common aetiologic agents identified were norovirus (54% of outbreaks), Salmonella enterica (21%) and Shiga toxin-producing Escherichia coli (10%). Food-handling errors were reported in 39% of outbreaks. The proportion of all foodborne outbreaks attributable to raw produce has been increasing. Evaluation of safety measures to address the contamination on farms, during processing and food preparation, should take into account the trends occurring before FSMA implementation.
