Increasing prevalence of diagnosed diabetes--United States and Puerto Rico, 1995-2010.

PubMed

2012-11-16

In 2010, an estimated 18.8 million persons in the United States had diagnosed diabetes mellitus and another 7.0 million had undiagnosed diabetes. Since 1990, the prevalence of diagnosed diabetes in the United States has risen sharply among all age groups, both sexes, and all racial/ethnic groups for which data are available. To learn whether the increase has been greater in some regions of the United States than in others, data on self-reported diabetes in adults collected during 1995-2010 by the Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. The analysis showed that the age-adjusted prevalence of diagnosed diabetes increased during the interval in every state, the District of Columbia (DC), and Puerto Rico. In 1995, age-adjusted prevalence was ≥6% in only three states, DC, and Puerto Rico, but by 2010 it was ≥6% in every state, DC, and Puerto Rico, and ≥10.0% in six states and Puerto Rico. Strategies to prevent diabetes and its preventable risk factors are needed, especially for those at highest risk for diabetes, to slow the rise in diabetes prevalence across the United States. Continued surveillance of diabetes prevalence and incidence, its risk factors, and prevention efforts is important to measure progress of prevention efforts.

There has been a well documented increase in the use and abuse of prescription opioids and heroin in the United States and other parts of the world. There has also been an increasing focus to increase access to the use of medications (methadone, buprenorphine, Naltrexone/Vivitrol) for opioid addicted individuals under legal supervision. As policymakers engage in strategic initiatives to better prevent and effectively treat chronic opioid addiction, both in the United States and other countries, there are a number of unintended consequences, complicating how best to increase access to effective treatment.

Twentieth Century Regional Climate Change During the Summer in the Central United States Attributed to Agricultural Intensification

NASA Astrophysics Data System (ADS)

Alter, Ross E.; Douglas, Hunter C.; Winter, Jonathan M.; Eltahir, Elfatih A. B.

2018-02-01

Both land use changes and greenhouse gas (GHG) emissions have significantly modified regional climate over the last century. In the central United States, for example, observational data indicate that rainfall increased, surface air temperature decreased, and surface humidity increased during the summer over the course of the twentieth century concurrently with increases in both agricultural production and global GHG emissions. However, the relative contributions of each of these forcings to the observed regional changes remain unclear. Results of both regional climate model simulations and observational analyses suggest that much of the observed rainfall increase—as well as the decrease in temperature and increase in humidity—is attributable to agricultural intensification in the central United States, with natural variability and GHG emissions playing secondary roles. Thus, we conclude that twentieth century land use changes contributed more to forcing observed regional climate change during the summer in the central United States than increasing GHG emissions.

Cadaver sources are insufficient for the increasing demand for liver transplantation. Right-lobe liver transplantation from living donors is fully developed in Japan and has been rapidly increasing in the United States during the past 2 years, although donor risk is greater than in other types of solid organ transplantation. The authors examine the psychiatric and ethical aspects of right-lobe liver transplantation in light of cultural differences between the United States and Japan.

Objectives In 1996, the U.S. Congress passed legislation making female genital mutilation/cutting (FGM/C) illegal in the United States. CDC published the first estimates of the number of women and girls at risk for FGM/C in 1997. Since 2012, various constituencies have again raised concerns about the practice in the United States. We updated an earlier estimate of the number of women and girls in the United States who were at risk for FGM/C or its consequences. Methods We estimated the number of women and girls who were at risk for undergoing FGM/C or its consequences in 2012 by applying country-specific prevalence of FGM/C to the estimated number of women and girls living in the United States who were born in that country or who lived with a parent born in that country. Results Approximately 513,000 women and girls in the United States were at risk for FGM/C or its consequences in 2012, which was more than three times higher than the earlier estimate, based on 1990 data. The increase in the number of women and girls younger than 18 years of age at risk for FGM/C was more than four times that of previous estimates. Conclusion The estimated increase was wholly a result of rapid growth in the number of immigrants from FGM/C-practicing countries living in the United States and not from increases in FGM/C prevalence in those countries. Scientifically valid information regarding whether women or their daughters have actually undergone FGM/C and related information that can contribute to efforts to prevent the practice in the United States and provide needed health services to women who have undergone FGM/C are needed.

The economic and ecological costs of wildfire in the United States have risen substantially in recent decades. Although climate change has likely enabled a portion of the increase in wildfire activity, the direct role of people in increasing wildfire activity has been largely overlooked. We evaluate over 1.5 million government records of wildfires that had to be extinguished or managed by state or federal agencies from 1992 to 2012, and examined geographic and seasonal extents of human-ignited wildfires relative to lightning-ignited wildfires. Humans have vastly expanded the spatial and seasonal "fire niche" in the coterminous United States, accounting for 84% of all wildfires and 44% of total area burned. During the 21-y time period, the human-caused fire season was three times longer than the lightning-caused fire season and added an average of 40,000 wildfires per year across the United States. Human-started wildfires disproportionally occurred where fuel moisture was higher than lightning-started fires, thereby helping expand the geographic and seasonal niche of wildfire. Human-started wildfires were dominant (>80% of ignitions) in over 5.1 million km 2 , the vast majority of the United States, whereas lightning-started fires were dominant in only 0.7 million km 2 , primarily in sparsely populated areas of the mountainous western United States. Ignitions caused by human activities are a substantial driver of overall fire risk to ecosystems and economies. Actions to raise awareness and increase management in regions prone to human-started wildfires should be a focus of United States policy to reduce fire risk and associated hazards.

Iron and obesity in females in the United States.

PubMed

Neymotin, Florence; Sen, Urmimala

2011-01-01

Since the late 1980s, the United States has witnessed a dramatic increase in average BMI levels and the proportion of individuals categorized as obese. Obesity is a major risk factor for a variety of illnesses, and an increase in obesity is, therefore, implicated in increased health-care costs in the United States. These ultimately translate to a major health and economic problem for the United States. The present analysis examines a pathway to increased levels of obesity as of yet almost entirely unexplored. Specifically, we examine the relationship between obesity and iron deficiency via analyses of blood samples. The current analysis employs public-use data files from the continuous National Health and Nutrition Examination Survey (NHANES) (1999-2006) survey to determine the relationship between obesity and an individual's iron blood content. Results suggest a negative relationship between levels of iron blood content and individual BMI after controlling for other individual characteristics. These results hold for nearly all eight panels tested in the ordinary least squares (OLS) regressions.

Decline in tuberculosis among Mexico-born persons in the United States, 2000-2010.

Baker, Brian J; Jeffries, Carla D; Moonan, Patrick K

2014-05-01

In 2010, Mexico was the most common (22.9%) country of origin for foreign-born persons with tuberculosis in the United States, and overall trends in tuberculosis morbidity are substantially influenced by the Mexico-born population. To determine the risk of tuberculosis disease among Mexico-born persons living in the United States. Using data from the U.S. National Tuberculosis Surveillance System and the American Community Survey, we examined tuberculosis case counts and case rates stratified by years since entry into the United States and geographic proximity to the United States-Mexico border. We calculated trends in case rates over time measured by average annual percent change. The total tuberculosis case count (-14.5%) and annual tuberculosis case rate (average annual percent change -5.1%) declined among Mexico-born persons. Among those diagnosed with tuberculosis less than 1 year since entry into the United States (newly arrived persons), there was a decrease in tuberculosis cases (-60.4%), no change in tuberculosis case rate (average annual percent change of 0.0%), and a decrease in population (-60.7%). Among those living in the United States for more than 5 years (non-recently arrived persons), there was an increase in tuberculosis cases (+3.4%), a decrease in tuberculosis case rate (average annual percent change of -4.9%), and an increase in population (+62.7%). In 2010, 66.7% of Mexico-born cases were among non-recently arrived persons, compared with 51.1% in 2000. Although border states reported the highest proportions (>15%) of tuberculosis cases that were Mexico-born, the highest Mexico-born-specific tuberculosis case rates (>20/100,000 population) were in states in the eastern and southeastern regions of the United States. The decline in tuberculosis morbidity among Mexico-born persons may be attributed to fewer newly arrived persons from Mexico and lower tuberculosis case rates among non-recently arrived Mexico-born persons. The extent of the decline was dampened by an unchanged tuberculosis case rate among newly arrived persons from Mexico and a large increase in the non-recently arrived Mexico-born population. If current trends continue, tuberculosis morbidity among Mexico-born persons will be increasingly driven by those who have been living in the United States for more than 5 years.

Effective promotion of breastfeeding among Latin American women newly immigrated to the United States.

Denman-Vitale, S; Murillo, E K

1999-07-01

Across the United States, advance practice nurses (APNs) are increasingly encountering recently immigrated Latin American populations. This article provides an overview of the situation of Latin Americans in the United States and discusses aspects of Latin American culture such as, respeto (respect), confianza (confidence), the importance of family, and the value of a personal connection. Strategies that will assist practitioners to incorporate culturally holistic principles in the promotion of breastfeeding among Latin American women who are new arrivals in the United States are described. If practitioners are to respond to the increasing numbers of Latin American women who need health care services, and also provide thorough, holistic health care then health care activities must be integrated with cultural competence.

Effects of increasing forest plantation area and management practices on carbon storage and water use in the United States

NASA Astrophysics Data System (ADS)

Chen, G.; Hayes, D. J.; Tian, H.

2013-12-01

Planted forest area in the United States gradually increased during the last half century, and by 2007 accounted for about 20% of the total forest area in the southern United States and about 13% in the entire country. Intensive plantation management activities - such as slash burning, thinning, weed control, fertilization and the use of genetically improved seedlings - are routinely applied during the forest rotation. However, no comprehensive assessments have been made to examine the impacts of this increased forest plantation area and associated management practices on ecosystem function. In this study, we integrated field measurement data and process-based modeling to quantitatively estimate the changes in carbon storage, nitrogen cycling and water use as influenced by forest plantations in the United States from 1925 to 2007. The results indicated that forest plantations and management practices greatly increased forest productivity, vegetation carbon, and wood product carbon storage in the United States, but slightly reduce soil carbon storage at some areas; however, the carbon sink induced by forest plantations was at the expense of more water use as represented by higher evapotranspiration. Stronger nitrogen and water limitations were found for forest plantations as compared to natural or naturally-regenerated forests.

Incidence, Survival, and Mortality of Malignant Cutaneous Melanoma in Wisconsin, 1995-2011.

PubMed

Peterson, Molly; Albertini, Mark R; Remington, Patrick

2015-10-01

To assess trends in malignant melanoma incidence, survival, and mortality in Wisconsin. Incidence data for Wisconsin were obtained from the Wisconsin Cancer Reporting System Bureau of Health Information using Wisconsin Interactive Statistics on Health, while incidence data for the United States were obtained from the Surveillance, Epidemiology, and End Results system (SEER). The mortality to incidence ratio [1 - (mortality/incidence)] was used as a proxy to estimate relative 5-year survival in Wisconsin, while observed 5-year survival rates for the United States were obtained from SEER. Mortality data for both Wisconsin and the United States were extracted using the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research. During the past decade, malignant melanoma incidence rates increased 57% in Wisconsin (from 12.1 to 19.0 cases per 100,000) versus a 33% increase (from 20.9 to 27.7 cases per 100,000) in the United States during the same time period. The greatest Wisconsin increase in incidence was among women ages 45-64 years and among men ages 65 years and older. Overall relative percent difference in 5-year survival in Wisconsin rose 10% (from 77% to 85%) and was unchanged (82%) for the United States. Wisconsin overall mortality rates were unchanged at 2.8 deaths per 100,000, compared to a 10% increase in the United States (from 3.1 to 3.4 deaths per 100,000). Wisconsin mortality rates improved for women ages 45-64 and for men ages 25-44. Despite improvements in malignant melanoma survival rates, increases in incidence represent a major public health challenge for physicians and policymakers.

Regional Warming from Aerosol Removal over the United States: Results from a Transient 2010-2050 Climate Simulation

NASA Technical Reports Server (NTRS)

Mickley, L. J.; Leibensperger, E. M.; Jacob, D. J.; Rind, D.

2012-01-01

We use a general circulation model (NASA Goddard Institute for Space Studies GCM 3) to investigate the regional climate response to removal of aerosols over the United States. We perform a pair of transient 2010e2050 climate simulations following a scenario of increasing greenhouse gas concentrations, with and without aerosols over the United States and with present-day aerosols elsewhere. We find that removing U.S. aerosol significantly enhances the warming from greenhouse gases in a spatial pattern that strongly correlates with that of the aerosol. Warming is nearly negligible outside the United States, but annual mean surface temperatures increase by 0.4e0.6 K in the eastern United States. Temperatures during summer heat waves in the Northeast rise by as much as 1e2 K due to aerosol removal, driven in part by positive feedbacks involving soil moisture and low cloud cover. Reducing U.S. aerosol sources to achieve air quality objectives could thus have significant unintended regional warming consequences.

Findings Among the states that legalized Sunday sales of alcoholic beverages, Delaware, Pennsylvania, and New Mexico experienced significant increases in overall alcohol consumption (P<0.05). However, the effect of the legalization of Sunday alcohol sales in Massachusetts and Rhode Island on per capita alcohol consumption was insignificant (P=0.964 and P=0.367). Conclusions Three out of five states in the USA that repealed their laws restricting Sunday sale of alcoholic beverages during 1990–2007, experienced significant increases in per capita alcohol consumption. This finding implies that increased alcohol availability leads to an increase in alcohol consumption. PMID:24103041

Although the prevalence of obesity is increasing worldwide, secular trends in elevated blood pressure (BP) differ across populations. We aimed to compare recent BP and obesity trends in adolescents aged 10-19 years in China, Korea, Seychelles and the United States of America. Data in adolescents aged 10-19 years came from China (1997-2011, n = 8025), Korea (1998-2012, n = 10 119), Seychelles (1998-2012, n = 27 569) and the United States of America (1999-2012, n = 14 580). Elevated BP was defined as SBP or DBP equal to or above the referent sex, age and height-specific 95th percentile of the US Fourth Report. Overweight and obesity were defined using criteria of the International Obesity Task Force. Between 1997-2000 and 2011-2012, the prevalence of elevated BP decreased in Korea and did not change substantially in China and in the United States of America. The prevalence of elevated BP increased in Seychelles. In 2011-2012, the prevalence of elevated BP was 1.7% in the United States of America, 3.8% in China, 3.7% in Korea and 14.3% in Seychelles. The prevalence of overweight and obesity increased over time and reached in 2011-2012 41.2% in the United States of America, 18.6% in China, 25.2% in Korea and 27.4% in Seychelles. Elevated BP was strongly associated with obesity in all countries. Although the prevalence of obesity increased markedly in the four countries, secular BP trends in adolescents differed in countries of different regions.

Hantavirus pulmonary syndrome (HPS) is a severe respiratory illness identified in 1993. Since its identification, the Centers for Disease Control and Prevention has obtained standardized information about and maintained a registry of all laboratory-confirmed HPS cases in the United States. During 1993-2009, a total of 510 HPS cases were identified. Case counts have varied from 11 to 48 per year (case-fatality rate 35%). However, there were no trends suggesting increasing or decreasing case counts or fatality rates. Although cases were reported in 30 states, most cases occurred in the western half of the country; annual case counts varied most in the southwestern United States. Increased hematocrits, leukocyte counts, and creatinine levels were more common in HPS case-patients who died. HPS is a severe disease with a high case-fatality rate, and cases continue to occur. The greatest potential for high annual HPS incidence exists in the southwestern United States.

Variability and trends in water-year runoff efficiency (RE) — computed as the ratio of water-year runoff (streamflow per unit area) to water-year precipitation — in the conterminous United States (CONUS) are examined for the 1951 through 2012 period. Changes in RE are analyzed using runoff and precipitation data aggregated to United States Geological Survey 8-digit hydrologic cataloging units (HUs). Results indicate increases in RE for some regions in the north-central CONUS and large decreases in RE for the south-central CONUS. The increases in RE in the north-central CONUS are explained by trends in climate, whereas the large decreases in RE in the south-central CONUS likely are related to groundwater withdrawals from the Ogallala aquifer to support irrigated agriculture.

Losses of Ammonia and Nitrate from Agriculture and Their Effect on Nitrogen Recovery in the European Union and the United States between 1900 and 2050.

Historical trends and levels of nitrogen (N) budgets and emissions to air and water in the European Union and the United States are markedly different. Agro-environmental policy approaches also differ, with emphasis on voluntary or incentive-based schemes in the United States versus a more regulatory approach in the European Union. This paper explores the implications of these differences for attaining long-term policy targets for air and water quality. Nutrient surplus problems were more severe in the European Union than in the United States during the 1970s and 1980s. The EU Nitrates and National Emission Ceilings directives contributed to decreases in fertilizer use, N surplus, and ammonia (NH) emissions, whereas in the United States they stabilized, although NH emissions are still increasing. These differences were analyzed using statistical data for 1900-2005 and the global IMAGE model. IMAGE could reproduce NH emissions and soil N surpluses at different scales (European Union and United States, country and state) and N loads in the Rhine and Mississippi. The regulation-driven changes during the past 25 yr in the European Union have reduced public concerns and have brought agricultural N loads to the aquatic environment closer to US levels. Despite differences in agro-environmental policies and agricultural structure (more N-fixing soybean and more spatially separated feed and livestock production in the United States than in the European Union), current N use efficiency in US and EU crop production is similar. IMAGE projections for the IAASTD-baseline scenario indicate that N loading to the environment in 2050 will be similar to current levels. In the United States, environmental N loads will remain substantially smaller than in the European Union, whereas agricultural production in 2050 in the United States will increase by 30% relative to 2005, as compared with an increase of 8% in the European Union. However, in the United States, even rigorous mitigation with maximum recycling of manure N and a 25% reduction in fertilizer use will not achieve the policy target to halve the N export to the Gulf of Mexico.

Over the past 15 years, the northeastern United States has seen a statistically significant increase in the frequency of extreme precipitation events that is larger and more widespread than anywhere else in the country. This increase in events is more likely to be associated with frontal and low-pressure systems, rather than being caused by more tropical cyclones impacting the region.

Recent droughts and associated heat waves have reached record intensity in some regions of the United States; however, by geographical scale and duration, the Dust Bowl era of the 1930s remains the benchmark drought and extreme heat event in the historical record (very high confidence). While by some measures drought has decreased over much of the continental United States in association with long-term increases in precipitation, neither the precipitation increases nor inferred drought decreases have been confidently attributed to anthropogenic forcing. The human effect on recent major U.S. droughts is complicated. Little evidence is found for a human influence on observed precipitation deficits, but much evidence is found for a human influence on surface soil moisture deficits due to increased evapotranspiration caused by higher temperatures. Future decreases in surface (top 10 cm) soil moisture from anthropogenic forcing over most of the United States are likely as the climate warms under higher scenarios. Substantial reductions in western U.S. winter and spring snowpack are projected as the climate warms. Earlier spring melt and reduced snow water equivalent have been formally attributed to human-induced warming (high confidence) and will very likely be exacerbated as the climate continues to warm (very high confidence). Under higher scenarios, and assuming no change to current water resources management, chronic, long-duration hydrological drought is increasingly possible by the end of this century. Detectable changes in some classes of flood frequency have occurred in parts of the United States and are a mix of increases and decreases. Extreme precipitation, one of the controlling factors in flood statistics, is observed to have generally increased and is projected to continue to do so across the United States in a warming atmosphere. However, formal attribution approaches have not established a significant connection of increased riverine flooding to human-induced climate change, and the timing of any emergence of a future detectable anthropogenic change in flooding is unclear. The incidence of large forest fires in the western United States and Alaska has increased since the early 1980s and is projected to further increase in those regions as the climate warms, with profound changes to certain ecosystems.

Precipitation and the occurrence of lyme disease in the Northeastern United States

2004-01-01

The occurrence of Lyme disease is a growing concern in the United States, and various studies have been performed to understand the factors related to Lyme disease occurrence. In the United States, Lyme disease has occurred most frequently in the northeastern United States. Positive correlations between the number of cases of Lyme disease reported in the northeastern United States during the 1992-2002 period indicate that late spring/early summer precipitation was a significant climate factor affecting the occurrence of Lyme disease. When late spring/early summer precipitation was greater than average, the occurrence of Lyme disease was above average, possibly due to increased tick activity and survival rate during wet conditions. Temperature did not seem to explain the variability in Lyme disease reports for the northeastern United States. ?? Mary Ann Liebert, Inc.

Over the past 10 years, there has been significant fluctuation in the yearly growth rates for cosmetic surgery procedures in both the United States and the United Kingdom. The authors compare cosmetic surgical procedure rates in the United Kingdom and United States with the macroeconomic climate of each region to determine whether there is a direct relationship between cosmetic surgery rates and economic health. The authors analyzed annual cosmetic surgery statistics from the British Association of Aesthetic Plastic Surgeons and the American Society for Aesthetic Plastic Surgery for 2002-2011 against economic indices from both regions, including the gross domestic product (GDP), consumer prices indices (CPI), and stock market reports. There was a 285.9% increase in the United Kingdom and a 1.1% increase in the United States in the number of procedures performed between 2002 and 2011. There were significant positive correlations between the number of cosmetic procedures performed in the United Kingdom and both the GDP (r = 0.986, P < .01) and CPI (r = 0.955, P < .01). Analysis of the US growth rates failed to show a significant relationship with any indices. UK interest rates showed a significant negative correlation (r = -0.668, P < .05) with procedures performed, whereas US interest rates showed a significant positive correlation. Data from the United States and United Kingdom suggest 2 very different growth patterns in the number of cosmetic surgeries being performed as compared with the economy in each region. Economic indices are accurate indicators of numbers of procedures being performed in the United Kingdom, whereas rates in the United States seem independent of those factors.

The principal rare earth elements deposits of the United States: A summary of domestic deposits and a global perspective

Long, Keith R.; Van Gosen, Bradley S.; Foley, Nora K.; Cordier, Daniel

2012-01-01

Demand for the rare earth elements (REE, lanthanide elements) is estimated to be increasing at a rate of about 8% per year due to increasing applications in consumer products, computers, automobiles, aircraft, and other advanced technology products. Much of this demand growth is driven by new technologies that increase energy efficiency and substitute away from fossil fuels. Production of these elements is highly concentrated in China, which is reducing its exports of REE raw materials as part of its industrial policy. The ability of the rest of the world to replace supply from China depends on the quality of known REE resources and the degree to which those resources have been explored and evaluated. A review of United States resources in a global context finds that the United States could make significant contributions to future REE production. Aside from two advanced projects in the United States and Australia, however, there are no REE projects advanced enough to meet short-term demand.

Regional nutrient trends in streams and rivers of the United States, 1993-2003

Trends in flow-adjusted concentrations (indicators of anthropogenic changes) and observed concentrations (indicators of natural and anthropogenic changes) of total phosphorus and total nitrogen from 1993 to 2003 were evaluated in the eastern, central, and western United States by adapting the Regional Kendall trend test to account for seasonality and spatial correlation. The only significant regional trend was an increase in flow-adjusted concentrations of total phosphorus in the central United States, which corresponded to increases in phosphorus inputs from fertilizer in the region, particularly west of the Mississippi River. A similar upward regional trend in observed total phosphorus concentrations in the central United States was not found, likely because precipitation and runoff decreased during drought conditions in the region, offsetting the increased source loading on the land surface. A greater number of regional trends would have been significant if spatial correlation had been disregarded, indicating the importance of spatial correlation modifications in regional trend assessments when sites are not spatially independent.

The increased risk for poor physical and mental health outcomes for older parents in Mexico who have an adult child living in the United States may contribute to an increased risk for cognitive impairment in this population. The objective of this study was to examine if older adults in Mexico who have one or more adult children living in the United States are more or less likely to develop cognitive impairment over an 11-year period compared to older adults who do not have any adult children living in the United States. Data for this study came from Wave I (2001) and Wave III (2012) of the Mexican Health and Aging Study. The final sample included 2609 participants aged 60 and over who were not cognitively impaired in 2001 and had one or more adult children (age ≥15). Participants were matched using a propensity score that was estimated with a multivariable logistic regression model that included sociodemographic characteristics and migration history of the older parents. Having one or more adult children living in the United States is associated with lower socioeconomic status and higher number of depressive symptoms, but greater social engagement for older parents living in Mexico. No significant differences in the odds for developing cognitive impairment according to having one or more adult children living in the United States were detected. In summary, having one or more adult children living in the United States was associated with characteristics that may increase and decrease the risk for cognitive impairment. This may contribute to the non-significant relationship between migration status of adult children and likelihood for cognitive impairment for older parents living in Mexico.

To estimate changes in the prevalence of daily cannabis use among current, former, and never cigarette smokers from 2002 to 2014 in the United States. The National Survey on Drug Use and Health is a nationally representative cross-sectional study conducted annually among persons aged 12 years and older in the United States. Daily cannabis use occurs nearly exclusively among nondaily and daily cigarette smokers compared with former and never smokers (8.03%, 9.01%, 2.79%, 1.05%, respectively). Daily cannabis use increased over the past decade among both nondaily (8.03% [2014] vs 2.85% [2002]; linear trend P < .001) and daily smokers (9.01% [2014]; 4.92% [2002]; linear trend P < .001). Daily cannabis use increased most rapidly among former cigarette smokers (2.79% [2014] vs 0.98% [2002]; linear trend P < .001). Daily cannabis use occurs predominantly among cigarette smokers in the United States. Daily cannabis use increased among current, former, and never smokers over the past decade, with particularly rapid increases among youth and female cigarette smokers. Future research is needed to monitor the observed increase in daily cannabis use, especially among youths and adults who smoke cigarettes.

Cigarette tax and public health: what are the implications of financially stressed smokers for the effects of price increases on smoking prevalence?

2011-03-01

This paper models the predicted impact of tobacco price increases proposed in the United States and Australia during 2009 on smoking prevalence in 2010 while taking account of the effects of financial stress among smokers on cessation rates. Two models of smoking prevalence were developed for each country. In model 1, prevalence rates were determined by price elasticity estimates. In model 2 price elasticity was moderated by financial stress. Each model was used to estimate smoking prevalence in 2010 in Australia and the United States. Proposed price increases resulted in a 1.89% and 7.84% decrease in smoking participation among low socio-economic status (SES) groups in the United States and Australia, respectively. Model 1 overestimated the number of individuals expected to quit in both the United States (0.13% of smokers) and Australia (0.36% of smokers) by failing to take account of the differential effects of the tax on financially stressed smokers. The proportion of low-income smokers under financial stress increased in both countries in 2010 (by 1.06% in the United States and 3.75% in Australia). The inclusion of financial stress when modelling the impact of price on smoking prevalence suggests that the population health returns of increased cigarette price will diminish over time. As it is likely that the proportion of low-income smokers under financial stress will also increase in 2010, future population-based approaches to reducing smoking will need to address this factor. © 2010 The Authors, Addiction © 2010 Society for the Study of Addiction.

Introduction The Centers for Disease Control and Prevention is considering implementation of overseas medical screening of student-visa applicants to reduce the numbers of active tuberculosis cases entering the United States. Objective To evaluate the costs, cases averted, and cost-effectiveness of screening for, and treating, tuberculosis in United States-bound students from countries with varying tuberculosis prevalence. Methods Costs and benefits were evaluated from two perspectives, combined and United States only. The combined perspective totaled overseas and United States costs and benefits from a societal perspective. The United States only perspective was a domestic measure of costs and benefits. A decision tree was developed to determine the cost-effectiveness of tuberculosis screening and treatment from the combined perspective. Results From the United States only perspective, overseas screening programs of Chinese and Indian students would prevent the importation of 157 tuberculosis cases annually, and result in $2.7 million in savings. From the combined perspective, screening programs for Chinese students would cost more than $2.8 million annually and screening programs for Indian students nearly $440,000 annually. From the combined perspective, the incremental cost for each tuberculosis case averted by screening Chinese and Indian students was $22,187 and $15,063, respectively. Implementing screening programs for German students would prevent no cases in most years, and would result in increased costs both overseas and in the United States. The domestic costs would occur because public health departments would need to follow up on students identified overseas as having an elevated risk of tuberculosis. Conclusions Tuberculosis screening and treatment programs for students seeking long term visas to attend United States schools would reduce the number of tuberculosis cases imported. Implementing screening in high-incidence countries could save the United States millions of dollars annually; however there would be increased costs incurred overseas for students and their families.

2015-10-01

Insulin is a vital medicine for patients with diabetes mellitus. Newer, more expensive insulin products and the lack of generic insulins in the United States have increased costs for patients and insurers. To examine Medicaid payment trends for insulin products. Cost information is available for all 50 states and has been recorded since the 1990s. A time-series analysis comparing reimbursements and prices. Using state- and national-level Medicaid data from 1991 to 2014, we identified all patients who used 1 or more of the 16 insulin products that were continuously available in the United States between 2006 and 2014. Insulin products were classified into rapid-acting and long-acting analogs, short-acting, intermediate, and premixed insulins based on American Diabetes Association Guidelines. Inflation-adjusted payments made to pharmacies by Medicaid per 1 mL (100 IU) of insulin in 2014 US dollars. Since 1991, Medicaid reimbursement per unit (1 mL) of insulin dispensed has risen steadily. In the 1990s, Medicaid reimbursed pharmacies between $2.36 and $4.43 per unit. By 2014, reimbursement for short-acting insulins increased to $9.64 per unit; intermediate, $9.22; premixed, $14.79; and long-acting, $19.78. Medicaid reimbursement for rapid-acting insulin analogs rose to $19.81 per unit. The rate of increase in reimbursement was higher for insulins with patent protection ($0.20 per quarter) than without ($0.05 per quarter) (P<.001).Total Medicaid reimbursements peaked at $407.4 million dollars in quarter 2 of 2014. Total volume peaked at 29.9 million units in quarter 4 of 2005 and was 21.2 million units in quarter 2 of 2014. Between 1991 and 2014, there was a near-exponential upward trend in Medicaid payments on a per-unit basis for a wide variety of insulin products regardless of formulation, duration of action, and whether the product was patented. Although reimbursements for newer, patent-protected insulin analogs increased at a faster rate than reimbursements for older insulins, payments increased for all products we examined. Our findings suggest a lack of price competition in the United States for this class of medications.

Strontium isotope values (87Sr/86Sr) in bone and tooth enamel have been used increasingly to identify non-local individuals within prehistoric human populations worldwide. Archaeological research in the Midwestern United States has increasingly highlighted the role of population movement in affecting interregional cultural change. However, the comparatively low level of geologic variation in the Midwestern United States might suggest a corresponding low level of strontium variation, and calls into question the sensitivity of strontium isotopes to identify non-local individuals in this region. Using strontium isotopes of archaeological fauna, we explore the degree of variability in strontium ratios across this region. Our results demonstrate measurable variation in strontium ratios and indicate the potential of strontium analysis for addressing questions of origin and population movement in the Midwestern United States.

Abstract Trends in the peak magnitude, frequency, duration, and volume of frequent floods (floods occurring at an average of two events per year relative to a base period) across the United States show large changes; however, few trends are found to be statistically significant. The multidimensional behavior of flood change across the United States can be described by four distinct groups, with streamgages experiencing (1) minimal change, (2) increasing frequency, (3) decreasing frequency, or (4) increases in all flood properties. Yet group membership shows only weak geographic cohesion. Lack of geographic cohesion is further demonstrated by weak correlations between the temporal patterns of flood change and large‐scale climate indices. These findings reveal a complex, fragmented pattern of flood change that, therefore, clouds the ability to make meaningful generalizations about flood change across the United States. PMID:27917010

Three push-pull chromophores comprising a triphenylamine (TPA) as electron-donating moiety and functionalized β-diketones as electron acceptor units are studied by various spectroscopic techniques. The time-correlated single-photon counting data shows that increasing the number of electron acceptor units accelerates photoluminescence relaxation rate of compounds. Transient spectra data shows that intramolecular charge transfer (ICT) takes place from TPA units to β-diketones units after photo-excitation. Increasing the number of electron acceptor units would prolong the generation process of ICT state, and accelerate the excited molecule reorganization process and the relaxation process of ICT state.

Policy implications of drug importation.

Palumbo, Francis B; Mullins, C Daniel; Slagle, Ashley F; Rizer, Jessica

2007-12-01

Importation of prescription drugs into the United States has been a major health policy issue for some time. The original objective of personal importation was to allow patients to have access to drugs that were not available to them in the United States either for continuation of therapy begun in another country or when all US Food and Drug Administration (FDA)-approved drug options for their condition had been exhausted. An increasing proportion of personally imported drugs are currently marketed in the United States, but imported drugs are presumably available at a lower cost to the consumer. As US consumers opt for importation through Internet sites and other means of purchase from other countries, potential risks of exposure to counterfeit products have increased, presenting challenges to both the US regulatory system and pharmaceutical companies. This commentary summarizes the current state of importation of prescription drugs into the United States. Regulators and policymakers are under increasing pressure to address the high cost of branded drugs in the United States and the desires of many US patients to purchase less expensive formulations of these products through importation. In many cases, the historical policies surrounding personal importation of prescription drugs that are not sold in the United States have been blatantly ignored, leaving the FDA in a quandary. While current legislative proposals would allow for greater access to drugs directly to consumers from other countries, they do not address the fact that the FDA has no ability to monitor the safety and efficacy of imported products. As such, the possibility of the entry of counterfeit medications and the related potential harm remain concerns.

Increases in thyroid nodule fine-needle aspirations, operations, and diagnoses of thyroid cancer in the United States.

Sosa, Julie Ann; Hanna, John W; Robinson, Karen A; Lanman, Richard B

2013-12-01

To provide population-based estimates of trends in thyroid nodule fine-needle aspirations (FNA) and operative volumes, we used multiple claims databases to quantify rates of these procedures and their association with the increasing incidence of thyroid cancer in the United States. Private and public insurance claims databases were used to estimate procedure volumes from 2006 to 2011. Rates of FNA and thyroid operations related to thyroid nodules were defined by CPT4 codes associated with International Classification of Diseases, Ninth Revision Clinical Modification codes for nontoxic uni- or multinodular goiter and thyroid neoplasms. Use of thyroid FNA more than doubled during the 5-year study period (16% annual growth). The number of thyroid operations performed for thyroid nodules increased by 31%. Total thyroidectomies increased by 12% per year, whereas lobectomies increased only 1% per year. In 2011, total thyroidectomies accounted for more than half (56%) of the operations for thyroid neoplasms in the United States. Thyroid operations became increasingly (62%) outpatient procedures. Thyroid FNA and operative procedures have increased rapidly in the United States, with an associated increase in the incidence of thyroid cancer. The more substantial increase in number of total versus partial thyroid resections suggests that patients undergoing thyroid operation are perceived to have a greater risk of cancer as determined by preoperative assessments, but this trend could also increase detection of incidental microcarcinomas.

Future of cancer incidence in the United States: burdens upon an aging, changing nation.

Smith, Benjamin D; Smith, Grace L; Hurria, Arti; Hortobagyi, Gabriel N; Buchholz, Thomas A

2009-06-10

By 2030, the United States' population will increase to approximately 365 million, including 72 million older adults (age > or = 65 years) and 157 million minority individuals. Although cancer incidence varies by age and race, the impact of demographic changes on cancer incidence has not been fully characterized. We sought to estimate the number of cancer patients diagnosed in the United States through 2030 by age and race. Current demographic-specific cancer incidence rates were calculated using the Surveillance Epidemiology and End Results database. Population projections from the Census Bureau were used to project future cancer incidence through 2030. From 2010 to 2030, the total projected cancer incidence will increase by approximately 45%, from 1.6 million in 2010 to 2.3 million in 2030. This increase is driven by cancer diagnosed in older adults and minorities. A 67% increase in cancer incidence is anticipated for older adults, compared with an 11% increase for younger adults. A 99% increase is anticipated for minorities, compared with a 31% increase for whites. From 2010 to 2030, the percentage of all cancers diagnosed in older adults will increase from 61% to 70%, and the percentage of all cancers diagnosed in minorities will increase from 21% to 28%. Demographic changes in the United States will result in a marked increase in the number of cancer diagnoses over the next 20 years. Continued efforts are needed to improve cancer care for older adults and minorities.

Overdose Deaths Involving Opioids, Cocaine, and Psychostimulants - United States, 2015-2016.

Seth, Puja; Scholl, Lawrence; Rudd, Rose A; Bacon, Sarah

2018-03-30

During 1999‒2015, 568,699 persons died from drug overdoses in the United States.* Drug overdose deaths in the United States increased 11.4% from 2014 to 2015 resulting in 52,404 deaths in 2015, including 33,091 (63.1%) that involved an opioid. The largest rate increases from 2014 to 2015 occurred among deaths involving synthetic opioids other than methadone (synthetic opioids) (72.2%) (1). Because of demographic and geographic variations in overdose deaths involving different drugs (2,3), † CDC examined age-adjusted death rates for overdoses involving all opioids, opioid subcategories (i.e., prescription opioids, heroin, and synthetic opioids), § cocaine, and psychostimulants with abuse potential (psychostimulants) by demographics, urbanization levels, and in 31 states and the District of Columbia (DC). There were 63,632 drug overdose deaths in 2016; 42,249 (66.4%) involved an opioid. ¶ From 2015 to 2016, deaths increased across all drug categories examined. The largest overall rate increases occurred among deaths involving cocaine (52.4%) and synthetic opioids (100%), likely driven by illicitly manufactured fentanyl (IMF) (2,3). Increases were observed across demographics, urbanization levels, and states and DC. The opioid overdose epidemic in the United States continues to worsen. A multifaceted approach, with faster and more comprehensive surveillance, is needed to track emerging threats to prevent and respond to the overdose epidemic through naloxone availability, safe prescribing practices, harm-reduction services, linkage into treatment, and more collaboration between public health and public safety agencies.

2017-10-03

Overweight and obesity are associated with increased risk of at least 13 different types of cancer. Data from the United States Cancer Statistics for 2014 were used to assess incidence rates, and data from 2005 to 2014 were used to assess trends for cancers associated with overweight and obesity (adenocarcinoma of the esophagus; cancers of the breast [in postmenopausal women], colon and rectum, endometrium, gallbladder, gastric cardia, kidney, liver, ovary, pancreas, and thyroid; meningioma; and multiple myeloma) by sex, age, race/ethnicity, state, geographic region, and cancer site. Because screening for colorectal cancer can reduce colorectal cancer incidence through detection of precancerous polyps before they become cancerous, trends with and without colorectal cancer were analyzed. In 2014, approximately 631,000 persons in the United States received a diagnosis of a cancer associated with overweight and obesity, representing 40% of all cancers diagnosed. Overweight- and obesity-related cancer incidence rates were higher among older persons (ages ≥50 years) than younger persons; higher among females than males; and higher among non-Hispanic black and non-Hispanic white adults compared with other groups. Incidence rates for overweight- and obesity-related cancers during 2005-2014 varied by age, cancer site, and state. Excluding colorectal cancer, incidence rates increased significantly among persons aged 20-74 years; decreased among those aged ≥75 years; increased in 32 states; and were stable in 16 states and the District of Columbia. The burden of overweight- and obesity-related cancer is high in the United States. Incidence rates of overweight- and obesity-related cancers except colorectal cancer have increased in some age groups and states. The burden of overweight- and obesity-related cancers might be reduced through efforts to prevent and control overweight and obesity. Comprehensive cancer control strategies, including use of evidence-based interventions to promote healthy weight, could help decrease the incidence of these cancers in the United States.

Prevalence of Human Papillomavirus in Oropharyngeal Squamous Cell Carcinoma in the United States Across Time

PubMed Central

2015-01-01

Human papillomaviruses (HPVs) are involved in approximately 5% of all human cancer. Although initially recognized for causing nearly all cases of cervical carcinoma, much data has now emerged implicating HPVs as a causal factor in other anogenital cancers as well as a subset of head and neck squamous cell carcinomas (HNSCCs), most commonly oropharyngeal cancers. Numerous clinical trials have demonstrated that patients with HPV+ oropharyngeal squamous cell carcinoma (OPSCC) have improved survival compared to patients with HPV– cancers. Furthermore, epidemiological evidence shows the incidence of OPSCC has been steadily rising over time in the United States. It has been proposed that an increase in HPV-related OPSCCs is the driving force behind the increasing rate of OPSCC. Although some studies have revealed an increase in HPV+ head and neck malignancies over time in specific regions of the United States, there has not been a comprehensive study validating this trend across the entire country. Therefore, we undertook this meta-analysis to assess all literature through August 2013 that reported on the prevalence of HPV in OPSCC for patient populations within the United States. The results show an increase in the prevalence of HPV+ OPSCC from 20.9% in the pre-1990 time period to 51.4% in 1990–1999 and finally to 65.4% for 2000–present. In this manner, our study provides further evidence to support the hypothesis that HPV-associated OPSCCs are driving the increasing incidence of OPSCC over time in the United States. PMID:24641254

The weather radar observations of ∼2,000 storms, on average, each summer that reach the altitude of rapidly increasing available inorganic chlorine, coupled with observed temperatures, portend a risk of initiating rapid heterogeneous catalytic conversion of inorganic chlorine to free radical form on ubiquitous sulfate−water aerosols; this, in turn, engages the element of risk associated with ozone loss in the stratosphere over the central United States in summer based upon the same reaction network that reduces stratospheric ozone over the Arctic. The summertime development of the upper-level anticyclonic flow over the United States, driven by the North American Monsoon, provides a means of retaining convectively injected water, thereby extending the time for catalytic ozone loss over the Great Plains. Trusted decadal forecasts of UV dosage over the United States in summer require understanding the response of this dynamical and photochemical system to increased forcing of the climate by increasing levels of CO2 and CH4.

Update on abortion policy.

Conti, Jennifer A; Brant, Ashley R; Shumaker, Heather D; Reeves, Matthew F

2016-12-01

To review the status of antiabortion restrictions enacted over the last 5 years in the United States and their impact on abortion services. In recent years, there has been an alarming rise in the number of antiabortion laws enacted across the United States. In total, various states in the union enacted 334 abortion restrictions from 2011 to July 2016, accounting for 30% of all abortion restrictions since the legalization of abortion in 1973. Data confirm, however, that more liberal abortion laws do not increase the number of abortions, but instead greatly decrease the number of abortion-related deaths. Several countries including Romania, South Africa and Nepal have seen dramatic decreases in maternal mortality after liberalization of abortion laws, without an increase in the total number of abortions. In the United States, abortions are incredibly safe with very low rates of complications and a mortality rate of 0.7 per 100 000 women. With increasing abortion restrictions, maternal mortality in the United States can be expected to rise over the coming years, as has been observed in Texas recently. Liberalization of abortion laws saves women's lives. The rising number of antiabortion restrictions will ultimately harm women and their families.

This study assesses the potential impacts on emissions and air quality from the increased adoption of natural gas-fired distributed generation of electricity (DG), including displacement of power from central power generation, in the contiguous United States. The study includes four major tasks: (1) modeling of distributed generation market penetration; (2) modeling of central power generation systems; (3) modeling of spatially and temporally resolved emissions; and (4) photochemical grid modeling to evaluate the potential air quality impacts of increased DG penetration, which includes both power-only DG and combined heat and power (CHP) units, for 2030. Low and high DG penetration scenarios estimate the largest penetration of future DG units in three regions - New England, New York, and California. Projections of DG penetration in the contiguous United States estimate 6.3 GW and 24 GW of market adoption in 2030 for the low DG penetration and high DG penetration scenarios, respectively. High DG penetration (all of which is natural gas-fired) serves to offset 8 GW of new natural gas combined cycle (NGCC) units, and 19 GW of solar photovoltaic (PV) installations by 2030. In all scenarios, air quality in the central United States and the northwest remains unaffected as there is little to no DG penetration in those states. California and several states in the northeast are the most impacted by emissions from DG units. Peak increases in maximum daily 8-h average ozone concentrations exceed 5 ppb, which may impede attainment of ambient air quality standards. Overall, air quality impacts from DG vary greatly based on meteorological conditions, proximity to emissions sources, the number and type of DG installations, and the emissions factors used for DG units.

The state of Massachusetts enacted universal health insurance in 2006. However it is unknown whether the increased access to care resulted in changes to surgical use or costs. We asked the following related research questions: compared with the United States as a whole, how did the (1) number of cases (as a percentage of the overall population, to account for changes in the overall population during the time surveyed), (2) payer mix, and (3) inpatient costs for arthroplasty change in Massachusetts after introduction of health insurance reform? We analyzed the use and cost of primary THAs and TKAs in Massachusetts using the State Inpatient Database (SID) between 2002 and 2011 compared with the Nationwide Inpatient Sample (NIS) during the same years. The SID captures 100% of inpatient procedures in Massachusetts, while the NIS is a nationally representative database of inpatient procedures for the United States. The SID and NIS are publicly available data sources from the Agency for Healthcare Research and Quality, and include information regarding procedure volumes, payer mixes, and costs. Inpatient costs were defined similarly in both databases by using hospital charges and an average cost-to-charge ratio that is unique for each hospital. The incidence of arthroplasties was calculated by dividing the procedure volume by the relevant population (either for Massachusetts or the entire country) based on public data from the United States Census bureau. The incidence of THAs and TKAs performed in Massachusetts increased steadily throughout the study period, and paralleled a similar increase in the United States as a whole. In Massachusetts, the incidence of THAs increased by 59% between 2002 and 2011, and the incidence of TKAs likewise increased by 80%. The trends for the incidence in total joint arthroplasties were similar to those for Massachusetts for the United States as a whole. The period of health insurance reform in Massachusetts was associated with a greater proportion of patients covered by Medicaid, Commonwealth Care, or Health Safety Net for THAs and TKAs. By 2011, universal health insurance in Massachusetts covered 2.45% of primary THAs and 2.77% of primary TKAs. Coverage for Medicaid in Massachusetts increased from 3.23% and 3.04% of THAs and TKAs in 2002 to 4.06% and 4.34% respectively in 2011. On average, Medicaid coverage was greater for TKAs in Massachusetts than across the United States during the study period. The introduction of health insurance reform had a minimal effect on the cost of total joint arthroplasties in Massachusetts. Although the costs of total joint arthroplasties in the United States were higher than those in Massachusetts, this difference narrowed substantially from 2002 to 2011, with the Massachusetts cost trending upward and the overall United States cost trending downward. Despite extending insurance coverage to the entire state of Massachusetts, there was little change in actual utilization trends for joint replacement. The enactment of universal health insurance coverage in Massachusetts appears to have been a nonevent insofar as the use and cost of total hip and knee surgeries is concerned in the state. Factors other than health insurance reform appear to be driving the growth in demand for arthroplasties in Massachusetts and are likely to do so as well in the United States under the Affordable Care Act of 2010.

Migration is suspected to increase risk for depressive and anxiety disorders. To test the hypothesized increase in risk for depressive and anxiety disorders after arrival in the United States among Mexican migrants. We combined data from surveys conducted separately in Mexico and the United States that used the same diagnostic interview. Discrete time survival models were specified to estimate the relative odds of first onset of depressive disorders (major depressive episode and dysthymia) and anxiety disorders (generalized anxiety disorder, social phobia, panic disorder, and posttraumatic stress disorder) among migrants after their arrival in the United States compared with nonmigrant Mexicans who have a migrant in their immediate family. Population surveys in the United States and Mexico. Two thousand five hundred nineteen nonmigrant family members of migrants in Mexico and 554 Mexican migrants in the United States. First onset of any depressive or anxiety disorder. After arrival in the United States, migrants had a significantly higher risk for first onset of any depressive or anxiety disorder than did nonmigrant family members of migrants in Mexico (odds ratio, 1.42; 95% confidence interval, 1.04-1.94). Associations between migration and disorder varied across birth cohorts. Elevated risk among migrants relative to nonmigrants was restricted to the 2 younger cohorts (those aged 18-25 or 26-35 years at interview). In the most recent birth cohort, the association between migration and first onset of any depressive or anxiety disorder was particularly strong (odds ratio, 3.89; 95% confidence interval, 2.74-5.53). This is, to our knowledge, the first study to compare risk for first onset of psychiatric disorder between representative samples of migrants in the United States and nonmigrants in Mexico. The findings are consistent with the hypothesized adverse effect of migration from Mexico to the United States on the mental health of migrants, but only among migrants in recent birth cohorts.

OBJECTIVE: To determine the association between measures of medical manpower available to treat trauma patients and county trauma death rates in the United States. The primary hypothesis was that greater availability of medical manpower to treat trauma injury would be associated with lower trauma death rates. SUMMARY BACKGROUND DATA: When viewed from the standpoint of the number of productive years of life lost, trauma has a greater effect on health care and lost productivity in the United States than any disease. Allocation of health care manpower to treat injuries seems logical, but studies have not been done to determine its efficacy. The effect of medical manpower and hospital resource allocation on the outcome of injury in the United States has not been fully explored or adequately evaluated. METHODS: Data on trauma deaths in the United States were obtained from the National Center for Health Statistics. Data on the number of surgeons and emergency medicine physicians were obtained from the American Hospital Association and the American Medical Association. Data on physicians who have participated in the American College of Surgeons (ACS) Advanced Trauma Life Support Course (ATLS) were obtained from the ACS. Membership information for the American Association for Surgery of Trauma (AAST) was obtained from that organization. Demographic data were obtained from the United States Census Bureau. Multivariate stepwise linear regression and cluster analysis were used to model the county trauma death rates in the United States. The Statistical Analysis System (Cary, NC) for statistical analysis was used. RESULTS: Bivariate and multivariate analyses showed that a variety of medical manpower measures and demographic factors were associated with county trauma death rates in the United States. As in other studies, measures of low population density and high levels of poverty were found to be strongly associated with increased trauma death rates. After accounting for these variables, using multivariate analysis and cluster analysis, an increase in the following medical manpower measures were associated with decreased county trauma death rates: number of board-certified general surgeons, number of board-certified emergency medicine physicians, number of AAST members, and number of ATLS-trained physicians. CONCLUSIONS: This study confirms previous work that showed a strong relation among measures of poverty, rural setting, and increased county trauma death rates. It also found that counties with more board-certified surgeons per capita and with more surgeons with an increased interest (AAST membership) or increased training (ATLS) in trauma care have lower per-capita trauma death rates.(ABSTRACT TRUNCATED AT 400 WORDS) Images Figure 1.

Effects of El Niño on summertime ozone air quality in the eastern United States

NASA Astrophysics Data System (ADS)

Shen, L.; Mickley, L. J.

2017-12-01

We investigate the effect of El Nino on maximum daily 8-hour average (MDA8) surface ozone over the eastern United States in summer (June-August, JJA) from 1980 to 2016. El Nino can influence the extra-tropical climate through the propagation of stationary waves, leading to (1) a low-pressure anomaly in the western Atlantic, which reduces transport of moist, clean air from the ocean into the mid- and southern Atlantic states, and (2) intensified southerly flow in the South Central states, which conversely enhances flux of moist, clean air into this region. El Nino can also trigger greater subsidence, reduced precipitation, and increased surface solar radiation in the mid- and southern Atlantic States. As a result, every standard deviation increase in the Nino 1+2 index is associated with an increase of 1-2 ppbv ozone in the Atlantic States and a decrease of 0.5-2 ppbv ozone in the South Central states. On average, models participating in the Atmospheric Model Intercomparison Project have difficulties capturing the El Nino influence on summertime weather in the eastern United States, implying that the freely running chemistry-climate models also cannot simulate the ozone variability related to El Nino.

World Opinion and the Soviet Satellite: A Preliminary Evaluation

NASA Technical Reports Server (NTRS)

1957-01-01

Less than two weeks after the launch of Sputnik I, the United States Information Agency conducted an informal analysis of public opinion on this subject. The analysis yielded four clear conclusions: (1) Soviet claims of scientific and technological superiority were widely accepted in the United States; (2) U.S. allies were concerned about a shift in the balance of military power; (3) the overall credibility of Soviet propaganda was greatly strengthened; and (4) American prestige was dealt a severe blow. The report also concluded that the near-hysteria in the United States in turn increased the level of concern in countries friendly to the United States. An evaluation is presented.

Trends in twin neonatal mortality rates in the United States, 1989 through 1999: influence of birth registration and obstetric intervention.

2004-05-01

We sought to evaluate the contributions of changes in birth registration, labor induction, and cesarean delivery on trends in twin neonatal mortality rates. We conducted a population-based, retrospective cohort study of twin live births, using linked birth-infant death data in the United States (1989-1999). Relative risks and 95% confidence intervals that quantified changes in neonatal (0-27 days) mortality rates were derived from ecologic logistic regression models that were fit after aggregation of the data by each state in the United States. The frequency of live born twins who weighed <500 g increased 72%, from 0.7% in 1989 to 1.2% in 1999, of live born twins who weighed 500 to 749 g and 750 to 999 g increased by 55% and 28%, respectively, between 1989 and 1999. Preterm birth rates increased by 19%, from 46.2% in 1989 to 57.2% in 1999. The rate of labor induction increased from 5.8% to 13.9%, and the cesarean delivery rate increased from 49.8% to 56.3%. Between 1989 to 1991 and 1997 to 1999, the crude neonatal mortality rates among twins who weighed >or=500 g declined by 37% (95% CI, 35%-40%) from 21.5 to 13.6 per 1000 twin live births. Adjustments for preterm labor induction, preterm cesarean delivery, term labor induction, term cesarean delivery, and sociodemographic factors had little influence on neonatal mortality rate trends. Increases in preterm birth because of obstetric intervention among twins have not led to increases in twin neonatal mortality rates in the United States.

Characterizing the HIV/AIDS Epidemic in the United States and China

The HIV/AIDS data from the national surveillance systems of China and the United States from 1985 to 2014 were compared to characterize the HIV/AIDS epidemic in both countries. The current estimated national HIV prevalence rate in China and the United States are 0.0598% and 0.348%, respectively. In the United States, the annual number of new HIV infections has remained relatively stable (~50,000 each year) and has shown a downward trend in recent years. The Chinese national HIV prevalence is still low, and new HIV infections have been contained at a low level (50,000–100,000 each year). However, the epidemic has showed an increasing trend since 2012. By risk group, in both countries, men who have sex with men (MSM), heterosexual sex, and injection drug use (IDU) are the most common modes of transmission of new HIV infections. However, in the United States, MSM is the dominant transmission route, accounting for >60% of new infections; whereas in China, heterosexual sex has now become the dominant route, also accounting for >60% of new infections. A rapid increase in the proportion of HIV cases that were attributed to MSM and an obvious decrease in the proportion of HIV cases attributed to IDU in China in recent years imply that the China’s epidemic is still evolving, to some extent, copying what was experienced in the United States. By age group, the proportions of HIV cases that were attributed to the age group 25–59 were comparable between the two countries. However, the United States had a higher proportion of cases that were attributed to age groups 15–19 and 20–24 than China, indicating that youth account for more infections in the United States. One other fact worth noting: in China there is a significant increase in the number of HIV new infections in individuals over 50 years of age, which results in much higher proportion of cases that were attributed to age groups 60–64 and over 65 in China than those in the United States. By race/ethnicity, in the United States, Blacks/African Americans continue to experience the most severe HIV burden, followed by Hispanics/Latinos. In China, no official data on race/ethnicity disparities are currently available. Thus, region, risk group, age are important factors in the HIV epidemics in both countries. PMID:26703667

Jirik, Stacey; Sanders, Sara

2014-01-01

The purpose of this article is to describe the state elder abuse statutes in the United States and Washington DC during 2011-2012. The last review of elder abuse statutes occurred in 2001; thus, a reexamination is warranted given the increased awareness of elder abuse at the state and national level and the growing number of older adults in the United States. This descriptive study analyzed the following components of elder or dependent abuse statutes: definitions, reporting requirements, training, and consequences for failure to report. It was determined that differences remain in how states respond to elder abuse at the community-based level.

The disposal of wastes associated with the processing of cotton is posing increasing problems for cotton gin operators in the western United States. Traditional disposal methods, such as open-air incineration and landfilling are no longer adequate due to increasing environmental concerns. This paper evaluates the technical, economic and environmental feasibility for cotton gin trash to serve as an energy resource. Cotton gin trash has been quantified, by county, in the five cotton-growing states of the western United States. The energy conversion technology that appears to offer the most promise is gasification. An economic evaluation model has been developed that willmore » allow gin operators to analyze their own situation to determine the profitability of converting gin trash to energy.« less

Synergy between publication and promotion: comparing adoption of new evidence in Canada and the United States.

Few studies have examined the effect of new evidence from clinical trials on physician practice. We took advantage of differences in promotional activity in Canada and the United States for the Heart Outcomes Prevention and Evaluation (HOPE) study and the Randomized Aldactone Evaluation Study (RALES) to determine if publication of new evidence changes practice, and the extent to which promotion influences adoption of new evidence. We used longitudinal dispensing data, collected from 1998 to 2001, to examine changes in prescribing patterns for ramipril and other angiotensin-converting enzyme (ACE) inhibitors before and after the HOPE study. We also obtained estimates for promotional expenditures. We stratified analyses by country, to isolate the effect of promotion, and used interrupted time series methods to adjust for pre-existing prescribing trends. Similar analyses were conducted for spironolactone use before and after RALES. Publication of the HOPE study results was associated with rapid increases in the use of ramipril. After adjusting for pre-existing prescribing trends, ramipril prescribing increased by 12% per month (P = 0.001) in Canada versus 5% per month (P = 0.001) in the United States after the study results were presented and published. One year later, ramipril accounted for 30% of the ACE inhibitor market in Canada versus 6% in the United States. The year before publication of these results, expenditures for detailing increased by 20% in Canada (to 18 US dollars per physician) but decreased by 7% in the United States (to 13 US dollars per physician); the year after publication, spending increased to 27 US dollars per physician in Canada versus 23 US dollars per physician in the United States. In the absence of promotional activity for RALES in either country, publication of results was associated with more modest but similar increases of 2% per month (P = 0.001) in spironolactone use in both countries. Publication of new evidence is associated with modest changes in practice. Promotional activity appears to increase the adoption of evidence. Rather than relying on the publication of articles and creation of guidelines, those wishing to accelerate the adoption of new evidence may need to undertake more active promotion.

Alcohol and Homicide in Russia and the United States: A Comparative Analysis*

PubMed Central

Landberg, Jonas; Norström, Thor

2011-01-01

Objective: The object of this study was to perform a comparative analysis of the aggregate relationship between alcohol and homicide in Russia and in the United States. The comparison was based on the magnitude of the alcohol effect, the alcohol attributable fraction (AAF), and the degree to which total consumption could account for trends in homicide. Method: We analyzed total and sex-specific homicide rates for the age groups 15–64 years, 15–34 years, and 35–64 years. The study period was 1959–1998 for Russia and 1950–2002 for the United States. For the United States, alcohol consumption was gauged by sales of alcohol; for Russia, estimated unrecorded consumption was included as well. The data were analyzed through autoregressive integrated moving average (ARIMA) modeling. Results: The results show that, for Russia as well as for the United States, a 1 -L increase in consumption was associated with an increase in homicides of about 10%, although the absolute effect was markedly larger in Russia because of differences in homicide rates. The AAF estimates suggested that 73% and 57% of the homicides would be attributable to alcohol in Russia and in the United States, respectively. Most of the temporal variation in the Russian homicide rate could be accounted for by the trend in drinking, whereas the U.S. trend in total alcohol consumption had a more limited ability to predict the trend in homicides. Conclusions: We conclude that the role of alcohol in homicide seems to be larger in Russia than in the United States. PMID:21906499

Iron and steel recycling in the United States in 1998

Fenton, Michael D.

2001-01-01

Consumption of iron and steel scrap and the health of the scrap industry depend directly on the health of the steelmaking industry. The United States, as well as most of the world, is expected to consume increasing amounts of scrap as a steadily increasing population demands more steel products. World resources of scrap should be sufficient for the foreseeable future. An estimated 75 million metric tons (Mt) of scrap was generated during 1998 in the United States, and 35 Mt of old scrap and 18 Mt of new scrap was consumed. The recycling efficiency was calculated to be 52%, and the recycling rate was found to be 41%. (See appendix for definitions.)

Amuedo-Dorantes, Catalina; Pozo, Susan; Puttitanun, Thitima

2015-12-01

Given the unprecedented increase in the flow of migrants from El Salvador, Guatemala, and Honduras to the United States, this article analyzes the impact of U.S. interior enforcement on parent-child separations among Central American deportees, along with its implications for deportees' intentions to remigrate to the United States. Using the EMIF sur survey data, we find that interior enforcement raises the likelihood of parent-child separations as well as the likelihood that parents forcedly separated from their young children report the intention to return to the United States, presumably without documents. By increasing parent-child separations, interior enforcement could prove counterproductive in deterring repetitive unauthorized crossings among Central American deportees.

International accreditation of ambulatory surgical centers and medical tourism.

McGuire, Michael F

2013-07-01

The two forces that have driven the increase in accreditation of outpatient ambulatory surgery centers (ASC's) in the United States are reimbursement of facility fees by Medicare and commercial insurance companies, which requires either accreditation, Medicare certification, or state licensure, and state laws which mandate one of these three options. Accreditation of ASC's internationally has been driven by national requirements and by the competitive forces of "medical tourism." The three American accrediting organizations have all developed international programs to meet this increasing demand outside of the United States. Copyright © 2013. Published by Elsevier Inc.

ABSTRACT: In this research initiative, the 2013-2014 NASA NICE workshop participants will present best educational practices for incorporating climate change pedagogy. The presentation will identify strategies to enhance instruction of pre-service teachers to aligned with K-12 Science, Technology, Engineering and Mathematics (STEM) standards. The presentation of best practices should serve as a direct indicator to address pedagogical needs to include climate education within a K-12 curriculum Some of the strategies will include inquiry, direct instructions, and cooperative learning . At this particular workshop, we have learned about global climate change in regards to how this is going to impact our life. Participants have been charged to increase the scientific understanding of pre-service teachers education programs nationally to incorporate climate education lessons. These recommended practices will provide feasible instructional strategies that can be easily implemented and used to clarify possible misconceptions and ambiguities in scientific knowledge. Additionally, the presentation will promote an awareness to the many facets in which climate change education can be beneficial to future learners and general public. The main scope is to increase the amount of STEM knowledge throughout the nations scientific literacy as we are using the platform of climate change. Federal entities which may include but not limited to National Security Agency and the Department of Homeland Security and Management will serve as resources partners for this common goal of having a more knowledgeable technological savvy and scientific literate society. The presentation will show that incorporating these best practices into elementary and early childhood education undergraduate programs will assist with increasing a enhance scientific literate society. As a measurable outcome have a positive impact on instructional effectiveness of future teachers. Their successfully preparing students in meeting the standards of the Common Core Initiative will attempt to measure across the curriculum uniformly.

Trends and outcomes of malignant hyperthermia in the United States, 2000 to 2005.

2009-01-01

Malignant hyperthermia (MH) is a potentially fatal pharmacogenetic disorder with an estimated mortality of less than 5%. The purpose of this study was to evaluate the current incidence of MH and the predictors associated with in-hospital mortality in the United States. The Nationwide Inpatient Sample, which is the largest all-payer inpatient database in the United States, was used to identify patients discharged with a diagnosis of MH during the years 2000-2005. The weighted exact Cochrane-Armitage test and multivariate logistic regression analyses were used to assess trends in the incidence and risk-adjusted mortality from MH, taking into account the complex survey design. From 2000 to 2005, the number of cases of MH increased from 372 to 521 per year. The occurrence of MH increased from 10.2 to 13.3 patients per million hospital discharges (P = 0.001). Mortality rates from MH ranged from 6.5% in 2005 to 16.9% in 2001 (P < 0.0001). The median age of patients with MH was 39 (interquartile range, 23-54 yr). Only 17.8% of the patients were children, who had lower mortality than adults (0.7% vs. 14.1%, P < 0.0001). Logistic regression analyses revealed that risk-adjusted in-hospital mortality was associated with increasing age, female sex, comorbidity burden, source of admission to hospital, and geographic region of the United States. The incidence of MH in the United States has increased in recent years. The in-hospital mortality from MH remains elevated and higher than previously reported. The results of this study should enable the identification of areas requiring increased focus in MH-related education.

Climate Change and Air Pollution-Related Health Impacts in the United States: Assessment of Current Findings

Kinney, P.; Fann, N.

Ambient air pollution can be affected by climate in a variety of ways, which in turn have important implications for human health. Observed and projected changes in climate lead to modified weather pat­terns and biogenic emissions, which influence the levels and geographic patterns of outdoor air pollutants of health concern, including ground-level ozone (O3) and fine particulate matter (PM2.5). The USGCRP scientific assessment of the human health impacts of climate change concluded with high confidence that climate change will make it harder for any given regulatory approach to reduce ground-level ozone pollution in the future as meteorological conditions become increasingly conducive to forming ozone over most of the United States. Unless offset by additional emissions reductions of ozone precursors, these climate-driven increases in ozone will cause premature deaths, hospital visits, lost school days, and acute respiratory symptoms. The evidence for climate impacts on PM2.5 is less robust than that for ozone. However, one mechanism through which climate change is likely to affect PM2.5 as well as O3 in the United States is via impacts on wildfires. Wildfires emit precursors of both fine particles and O3, which increase the risk of premature death and adverse chronic and acute cardiovascular and respiratory health outcomes. Climate change is projected to increase the number and severity of naturally occurring wildfires in parts of the United States, increasing emissions of particulate matter and ozone precursors and resulting in additional adverse health outcomes. We present the key results and conclusions from a nationwide assessment of O3 health impacts in 2030, as well as new evidence for respiratory health effects of wildfires in the western United States.

Chloride concentrations are increasing at a rate that threatens the availability of fresh water in the northeastern United States. Increases in roadways and deicer use are now salinizing fresh waters, degrading habitat for aquatic organisms, and impacting large supplies of drinking water for humans throughout the region. We observed chloride concentrations of up to 25% of the concentration of seawater in streams of Maryland, New York, and New Hampshire during winters, and chloride concentrations remaining up to 100 times greater than unimpacted forest streams during summers. Mean annual chloride concentration increased as a function of impervious surface and exceeded tolerance for freshwater life in suburban and urban watersheds. Our analysis shows that if salinity were to continue to increase at its present rate due to changes in impervious surface coverage and current management practices, many surface waters in the northeastern United States would not be potable for human consumption and would become toxic to freshwater life within the next century.

Intestinal parasitism in the United States: update on a continuing problem.

PubMed

Kappus, K D; Lundgren, R G; Juranek, D D; Roberts, J M; Spencer, H C

1994-06-01

To document patterns of intestinal parasitism in the United States, we analyzed results of 216,275 stool specimens examined by the state diagnostic laboratories in 1987; parasites were found in 20.0%. Percentages were highest for protozoans: Giardia lamblia (7.2%), Entamoeba coli and Endolimax nana (4.2% each), Blastocystis hominis (2.6%), and Entamoeba histolytica (0.9%). The most commonly identified helminths were nematodes: hookworm (1.5%), Trichuris trichiura (1.2%), and Ascaris lumbricoides (0.8%). Identifications of G. lamblia increased broadly from the 4.0% average found in 1979, with 40 states reporting increases and seven reporting decreases. Seasonally, Giardia identifications increased in the summer and fall, especially in the Midwest. Nine states reported hookworms in more than 2% of specimens; none were states with indigenous transmission. We analyzed similar, but abbreviated, data for 1991; parasites were found in 19.7% of the 178,786 specimens and Giardia was found in 5.6%. States reporting percentages of Giardia identification in the highest quartile for both 1987 and 1991 were located in the Midwest or in the Northwest. Cryptosporidium was identified in both the 1987 and 1991 surveys; it had not been identified in a previous survey. For each year, Cryptosporidium was reported from 25 states across the country (for both years in 17 states). We conclude that intestinal parasitism should not be overlooked as a cause of gastrointestinal illness in the United States and that the prevalence of Giardia may be increasing.

The effect of lack of insurance, poverty and paediatrician supply on immunization rates among children 19-35 months of age in the United States.

PubMed

Becton, James L; Cheng, Lee; Nieman, Linda Z

2008-04-01

Previous studies found that the increasing number of paediatricians in the United States was associated with improved childhood immunization coverage, while the increasing poverty level and the lack of health insurance reduced access to health care. We evaluated whether changes in the number of paediatricians, poverty level and health insurance affected national childhood immunization coverage in the state levels of the United States. Data were collected primarily from the US National Immunization Surveys, series 4:3:1:3:3 from years 1995 and 2003. Ordinal logistic regression analysis was used to analyse the relationships among variables. Over 8 years studied, immunization coverage increased for children aged 19-35 months from 52.3% to 79.8% in the 50 states. The average number of paediatricians per 1000 births increased 28.7% while the percentage of children without health insurance declined 15.6%, and the percentage of children who lived in poverty level declined 17.3%. In 1995, the states with higher immunization coverage were associated with higher numbers of paediatricians [odds ratio (OR), 32.73; 95% confidence interval (CI), 5.96-179.77]. In 2003, the higher numbers of paediatricians still played a role in the increased immunization coverage (OR, 4.69; 95% CI, 1.01-21.78); however, the higher rate of uninsured children in 2003 had an even greater effect upon immunization coverage. Compared with states with lower rates of uninsured children, states with intermediate and higher rates of uninsured children had sixfold (OR, 0.16; 95% CI, 0.03-0.81) and 16-fold (OR, 0.06; 95% CI, 0.01-0.40) decreased childhood immunization coverage, respectively. Between 1995 and 2003 in the United States, the lack of health insurance became more prominent than the supply of paediatricians in affecting immunization coverage for children aged 19-35 months. Future improvements in insurance coverage for children will likely lead to greater immunization coverage.

HIV and Mexican migrant workers in the United States: a review applying the vulnerable populations conceptual model.

PubMed

Albarrán, Cynthia R; Nyamathi, Adeline

2011-01-01

Mexican migrant workers residing in the United States are a vulnerable population at high risk for HIV infection. This article critically appraises the published data surrounding HIV prevalence in this vulnerable group, as seen through the lens of the Vulnerable Populations Conceptual Model. This model demonstrates how exposure to risk and resource availability affect health status. The health status of Mexican migrants in the United States is compromised by a number of factors that increase risk of HIV: limited access to health services, multiple sexual partners, low rates of condom use, men having sex with men, and lay injection practices. Migration from Mexico to the United States has increased the prevalence of HIV in rural Mexico, making this an issue of urgent binational concern. This review highlights the implications for further nursing research, practice, and policy. Copyright © 2011 Association of Nurses in AIDS Care. Published by Elsevier Inc. All rights reserved.

Latency attention deficit: Asbestos abatement workers need us to investigate.

Roelofs, Cora

2015-12-01

Little is known of the impact of asbestos on the health of the workers in the United States who have removed or abated asbestos from buildings following recognition of its adverse effects on health. The United States does not have a national occupational health surveillance network to monitor asbestos-related disease and, while the United States Occupational Health and Safety Administration has a strong and detailed asbestos standard, its enforcement resources are limited. A significant proportion of asbestos abatement workers are foreign-born, and may face numerous challenges in achieving safe workplaces, including lack of union representation, economic vulnerability, and inadequate training. Public health surveillance and increased and coordinated enforcement is needed to monitor the health and exposure experiences of asbestos-exposed workers. Alarming disease trends in asbestos removal workers in Great Britain suggest that, in the United States, increased public attention will be necessary to end the epidemic of asbestos-related disease. © 2015 Wiley Periodicals, Inc.

Objective: This study aimed to investigate the quantitative effects of outdoor air pollution, represented by 10 µg/m3 increment of PM10, on chronic obstructive pulmonary disease in China, United States and European Union through systematic review and meta-analysis. Methods: Publications in English and Chinese from PubMed and EMBASE were selected. The Cochrane Review Handbook of Generic Inverse Variance was used to synthesize the pooled effects on incidence, prevalence, mortality and hospital admission. Results: Outdoor air pollution contributed to higher incidence and prevalence of COPD. Short-term exposure was associated with COPD mortality increased by 6%, 1% and 1% in the European Union, the United States and China, respectively (p < 0.05). Chronic PM exposure produced a 10% increase in mortality. In a short-term exposure to 10 µg/m3 PM10 increment COPD mortality was elevated by 1% in China (p < 0.05) and hospital admission enrollment was increased by 1% in China, 2% in United States and 1% in European Union (p < 0.05). Conclusions: Outdoor air pollution contributes to the increasing burdens of COPD.10 µg/m3 increase of PM10 produced significant condition of COPD death and exacerbation in China, United States and European Union. Controlling air pollution will have substantial benefit to COPD morbidity and mortality. PMID:25405599

The magnitude and frequency of hydrometeorological extremes are expected to increase in the conterminous United States (CONUS) over the rest of this century, and their increase will significantly impact water resource management. While previous efforts focused on the effects of reservoirs on downstream discharge, the effects of climate change on reservoir inflows in upstream areas are not well understood. We evaluated the large-scale climate change effects on extreme hydrological events and their implications for reservoir inflows in 178 headwater basins across CONUS using the Variable Infiltration Capacity (VIC) hydrologic model. The VIC model was forced with a 10-member ensemble ofmore » global circulation models under the Representative Concentration Pathway 8.5 that were dynamically downscaled using a regional climate model (RegCM4) and bias-corrected to 1/24° grid cell resolution. The results projected an increase in the likelihood of flood risk by 44% for a majority of subbasins upstream of flood control reservoirs in the central United States and increased drought risk by 11% for subbasins upstream of hydropower reservoirs across the western United States. Increased risk of both floods and droughts can potentially make reservoirs across CONUS more vulnerable to future climate conditions. In conclusion, this study estimates reservoir inflow changes over the next several decades, which can be used to optimize water supply management downstream.« less

Background Overweight and obesity are associated with increased risk of at least 13 different types of cancer. Methods Data from the United States Cancer Statistics for 2014 were used to assess incidence rates, and data from 2005 to 2014 were used to assess trends for cancers associated with overweight and obesity (adenocarcinoma of the esophagus; cancers of the breast [in postmenopausal women], colon and rectum, endometrium, gallbladder, gastric cardia, kidney, liver, ovary, pancreas, and thyroid; meningioma; and multiple myeloma) by sex, age, race/ethnicity, state, geographic region, and cancer site. Because screening for colorectal cancer can reduce colorectal cancer incidence through detection of precancerous polyps before they become cancerous, trends with and without colorectal cancer were analyzed. Results In 2014, approximately 631,000 persons in the United States received a diagnosis of a cancer associated with overweight and obesity, representing 40% of all cancers diagnosed. Overweight- and obesity-related cancer incidence rates were higher among older persons (ages ≥50 years) than younger persons; higher among females than males; and higher among non-Hispanic black and non-Hispanic white adults compared with other groups. Incidence rates for overweight- and obesity-related cancers during 2005–2014 varied by age, cancer site, and state. Excluding colorectal cancer, incidence rates increased significantly among persons aged 20–74 years; decreased among those aged ≥75 years; increased in 32 states; and were stable in 16 states and the District of Columbia. Conclusions The burden of overweight- and obesity-related cancer is high in the United States. Incidence rates of overweight- and obesity-related cancers except colorectal cancer have increased in some age groups and states. Implications for Public Health Practice The burden of overweight- and obesity-related cancers might be reduced through efforts to prevent and control overweight and obesity. Comprehensive cancer control strategies, including use of evidence-based interventions to promote healthy weight, could help decrease the incidence of these cancers in the United States.

The American Society of Transplantation (AST) and American Society of Transplant Surgeons (ASTS) convened a workshop on June 2-3, 2014, to explore increasing both living and deceased organ donation in the United States. Recent articles in the lay press on illegal organ sales and transplant tourism highlight the impact of the current black market in kidneys that accompanies the growing global organ shortage. We believe it important not to conflate the illegal market for organs, which we reject in the strongest possible terms, with the potential in the United States for concerted action to remove all remaining financial disincentives for donors and critically consider testing the impact and acceptability of incentives to increase organ availability in the United States. However, we do not support any trials of direct payments or valuable considerations to donors or families based on a process of market-assigned values of organs. This White Paper represents a summary by the authors of the deliberations of the Incentives Workshop Group and has been approved by both AST and ASTS Boards. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Waterpipe Smoking and Regulation in the United States: A Comprehensive Review of the Literature.

Researchers in tobacco control are concerned about the increasing prevalence of waterpipe smoking in the United States, which may pose similar risks as cigarette smoking. This review explores the prevalence of waterpipe smoking in the United States as well as the shortcomings of current U.S. policy for waterpipe control and regulation. Researchers conducted a literature review for waterpipe articles dated between 2004 and 2015 using five online databases: MEDLINE, CINHAHL, ScienceDirect, PMC, and Cochrane Library. To date, few studies have explored the marketing and regulation of waterpipe smoking in the U.S., which has increased in the last ten years, especially among women, adolescents, and young adults. Data indicate that the majority of waterpipe smokers are unaware of the potential risks of use. In addition, current tobacco control policies do not address waterpipe smoking, enabling tobacco companies to readily market and sell waterpipe products to young adults, who are at risk for becoming lifelong smokers. Policy makers in the area of public health need to update existing tobacco regulations to include waterpipe smoking. Similarly, public health researchers should develop public health campaigns and interventions to address the increasing rates of waterpipe smoking in the United States.

2018-04-30

There are many similarities in the epidemiology and transmission of hepatitis A virus (HAV) and hepatitis E virus (HEV) genotype (gt)3 infections in the United States. Both viruses are enterically transmitted, although specific routes of transmission are more clearly established for HAV than for HEV: HAV is restricted to humans and primarily spread through the fecal-oral route, while HEV is zoonotic with poorly understood modes of transmission in the United States. New cases of HAV infection have decreased dramatically in the United States since infant vaccination was recommended in 1996. In recent years, however, outbreaks have occurred among an increasingly susceptible adult population. Although HEV is the most common cause of acute viral hepatitis in developing countries, it is rarely diagnosed in the United States.

The United States is the largest refugee resettlement country in the world. Refugees may face health-related challenges after resettlement in the United States, including higher rates of chronic diseases due to problems such as language barriers and difficulty adapting to new food environments. However, reported refugee diet challenges varied, and no systematic examination has been reported. This study examined refugee food intake pre- and postresettlement in the United States and differences in intake across various refugee groups. We systematically reviewed relevant studies that reported on refugee food intake and adaptation to the US food environment. We searched PubMed for literature published between January 1985 and April 2015, including cross-sectional and prospective studies. Eighteen studies met inclusion criteria. Limited research has been conducted, and most studies were based on small convenience samples. In general, refugees increased meat and egg consumption after resettling in the United States. Changes in refugee intake of vegetables, fruits, and dairy products varied by socioeconomic status, food insecurity, past food deprivation experience, length of stay in the United States, region of origin, and age. South Asians were more likely to maintain traditional diets, and increased age was associated with more conservative and traditional diets. Despite the abundance of food in the United States, postresettlement refugees reported difficulty in finding familiar or healthy foods. More research with larger samples and follow-up data are needed to study how refugees adapt to the US food environment and what factors may influence their food- and health-related outcomes. The work could inform future interventions to promote healthy eating and living among refugees and help to reduce health disparities. PMID:28140324

Tuberculosis (TB) is a leading public health problem and a recognized priority for the federal Governments of both Mexico and the United States of America. The objectives of this research, primarily for the four states in the United States that are along the border with Mexico, were to: (1) describe the epidemiological situation of TB, (2) identify TB risk factors, and (3) discuss tuberculosis program strategies. We analyzed tuberculosis case reports collected from 1993 through 2001 by the tuberculosis surveillance system of the United States. We used those data to compare TB cases mainly among three groups: (1) Mexican-born persons in the four United States border states (Arizona, California, New Mexico, and Texas), (2) persons in those four border states who had been born in the United States, and (3) Mexican-born persons in the 46 other states of the United States, which do not border Mexico. For the period from 1993 through 2001, of the 16 223 TB cases reported for Mexican-born persons in the United States, 12 450 of them (76.7%) were reported by Arizona, California, New Mexico, and Texas. In those four border states overall in 2001, tuberculosis case rates for Mexican-born persons were 5.0 times as high as the rates for persons born in the United States; those four states have 23 counties that directly border on Mexico, and the ratio in those counties was 5.8. HIV seropositivity, drug and alcohol use, unemployment, and incarceration were significantly less likely to be reported in Mexican-born TB patients from the four border states and the nonborder states than in patients born in the United States from the four border states (P < 0.001). Multivariate analysis revealed that among pulmonary tuberculosis patients who were 18-64 years of age and residing in the four border states, the Mexican-born patients were 3.6 times as likely as the United States-born patients were to have resistance to at least isoniazid and rifampin (i. e., to have multidrug-resistant TB) and twice as likely to have isoniazid resistance. Mexican-born TB patients from the four border states and the nonborder states were significantly more likely to have moved or to be lost to follow-up than were the TB patients born in the United States from the four border states (P < 0.001). Increased collaborative tuberculosis control efforts by the federal Governments of both Mexico and the United States along the border that they share are needed if tuberculosis is to be eliminated in the United States.

Comparing Generic Drug Markets in Europe and the United States: Prices, Volumes, and Spending.

Wouters, Olivier J; Kanavos, Panos G; McKEE, Martin

Policy Points: Our study indicates that there are opportunities for cost savings in generic drug markets in Europe and the United States. Regulators should make it easier for generic drugs to reach the market. Regulators and payers should apply measures to stimulate price competition among generic drugmakers and to increase generic drug use. To meaningfully evaluate policy options, it is important to analyze historical context and understand why similar initiatives failed previously. Rising drug prices are putting pressure on health care budgets. Policymakers are assessing how they can save money through generic drugs. We compared generic drug prices and market shares in 13 European countries, using data from 2013, to assess the amount of variation that exists between countries. To place these results in context, we reviewed evidence from recent studies on the prices and use of generics in Europe and the United States. We also surveyed peer-reviewed studies, gray literature, and books published since 2000 to (1) outline existing generic drug policies in European countries and the United States; (2) identify ways to increase generic drug use and to promote price competition among generic drug companies; and (3) explore barriers to implementing reform of generic drug policies, using a historical example from the United States as a case study. The prices and market shares of generics vary widely across Europe. For example, prices charged by manufacturers in Switzerland are, on average, more than 2.5 times those in Germany and more than 6 times those in the United Kingdom, based on the results of a commonly used price index. The proportion of prescriptions filled with generics ranges from 17% in Switzerland to 83% in the United Kingdom. By comparison, the United States has historically had low generic drug prices and high rates of generic drug use (84% in 2013), but has in recent years experienced sharp price increases for some off-patent products. There are policy solutions to address issues in Europe and the United States, such as streamlining the generic drug approval process and requiring generic prescribing and substitution where such policies are not yet in place. The history of substitution laws in the United States provides insights into the economic, political, and cultural issues influencing the adoption of generic drug policies. Governments should apply coherent supply- and demand-side policies in generic drug markets. An immediate priority is to convince more physicians, pharmacists, and patients that generic drugs are bioequivalent to branded products. Special-interest groups continue to obstruct reform in Europe and the United States. © 2017 The Authors The Milbank Quarterly published by Wiley Periodicals, Inc. on behalf of The Millbank Memorial Fund.

However, displacement of suicide method from domestic gas to car exhaust occurred only for males and not for females.

Arms Against Illness: Crack Cocaine and Drug Policy in the United States.

PubMed

Watkins; Fullilove; Fullilove

1998-01-01

The emergence of crack cocaine use in the United States during the mid-1980s was one of the most significant public health problems of that era. Crack use contributed to a series of sexually transmitted disease epidemics, to epidemic increases in violent injuries and homicides, and to significant increases in the incidence and prevalence of cocaine addiction. Despite these threats to health and safety, a national public health campaign to counter crack-related morbidity and mortality was never mounted. To the contrary, the strongest response to the crack epidemic has come from the police and the courts. As a result, crack-related crimes have accounted for dramatic increases in the numbers of adolescents and adults imprisoned in the United States. Scarce attention to the public health dimensions of these policies, let alone the human rights implications, has been catastrophic for affected individuals and communities.

West Nile virus (WNV) is a leading cause of mosquito-borne disease in the United States. Annual seasonal outbreaks vary in size and location. Predicting where and when higher than normal WNV transmission will occur can help direct limited public health resources. We developed models for the contiguous United States to identify meteorological anomalies associated with above average incidence of WNV neuroinvasive disease from 2004 to 2012. We used county-level WNV data reported to ArboNET and meteorological data from the North American Land Data Assimilation System. As a result of geographic differences in WNV transmission, we divided the United States into East and West, and 10 climate regions. Above average annual temperature was associated with increased likelihood of higher than normal WNV disease incidence, nationally and in most regions. Lower than average annual total precipitation was associated with higher disease incidence in the eastern United States, but the opposite was true in most western regions. Although multiple factors influence WNV transmission, these findings show that anomalies in temperature and precipitation are associated with above average WNV disease incidence. Readily accessible meteorological data may be used to develop predictive models to forecast geographic areas with elevated WNV disease risk before the coming season. © The American Society of Tropical Medicine and Hygiene.

Accidental introductions are an important source of invasive plants in the continental United States.

2013-07-01

Preventing new plant invasions is critical for reducing large-scale ecological change. Most studies have focused on the deliberate introduction of nonnatives via the ornamental plant trade. However, accidental introduction may be an important source of nonnative, invasive plants. Using Web and literature searches, we compiled pathways of introduction to the United States for 1112 nonnative plants identified as invasive in the continental United States. We assessed how the proportion of accidentally and deliberately introduced invasive plants varies over time and space and by growth habit across the lower 48 states. Deliberate introductions of ornamentals are the primary source of invasive plants in the United States, but accidental introductions through seed contaminants are an important secondary source. Invasive forbs and grasses are the most likely to have arrived accidentally through seed contaminants, while almost all nonnative, invasive trees were introduced deliberately. Nonnative plants invading eastern states primarily arrived deliberately as ornamentals, while a high proportion of invasive plants in western states arrived accidentally as seed contaminants. Accidental introductions may be increasing in importance through time. Before 1850, 10 of 89 (11%) of invasive plants arrived accidentally. After 1900, 20 of 65 (31%) arrived accidentally. Recently enacted screening protocols and weed risk assessments aim to reduce the number of potentially invasive species arriving to the United States via deliberate introduction pathways. Increasing proportions of accidentally introduced invasive plants, particularly associated with contaminated seed imports across the western states, suggest that accidental introduction pathways also need to be considered in future regulatory decisions.

Andersen, Ronald; Hull, John T.

1969-01-01

Differences in hospital costs and utilization between the United States and Canada are analyzed and an attempt made to measure the significance of various demographic, economic, and other factors thought to be related to the differences. Increases in utilization are traced to population increases and to actual increased use per person; and cost increases tied to general inflationary trends are separated from those attributable to specific hospital price increases. Differences in the financing and reimbursement mechanisms in the two countries are shown to have had little effect on relative cost increases, which in the period under consideration were parallelled by similar or greater increases in other industrialized nations.

Physician referrals play a central role in ambulatory care in the United States; however, little is known about national trends in physician referrals over time. The objective of this study was to assess changes in the annual rate of referrals to other physicians from physician office visits in the United States from 1999 to 2009. We analyzed nationally representative cross-sections of ambulatory patient visits in the United States, using a sample of 845 243 visits from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 1993 to 2009, focusing on the decade from 1999 to 2009. The main outcome measures were survey-weighted estimates of the total number and percentage of visits resulting in a referral to another physician across several patient and physician characteristics. From 1999 to 2009, the probability that an ambulatory visit to a physician resulted in a referral to another physician increased from 4.8% to 9.3% (P < .001), a 94% increase. The absolute number of visits resulting in a physician referral increased 159% nationally during this time, from 41 million to 105 million. This trend was consistent across all subgroups examined, except for slower growth among physicians with ownership stakes in their practice (P = .02) or those with the majority of income from managed care contracts (P = .007). Changes in referral rates varied according to the principal symptoms accounting for patients' visits, with significant increases noted for visits to primary care physicians from patients with cardiovascular, gastrointestinal, orthopedic, dermatologic, and ear/nose/throat symptoms. The percentage and absolute number of ambulatory visits resulting in a referral in the United States grew substantially from 1999 to 2009. More research is necessary to understand the contribution of rising referral rates to costs of care.

Technical options for processing additional light tight oil volumes within the United States

EIA Publications

2015-01-01

This report examines technical options for processing additional LTO volumes within the United States. Domestic processing of additional LTO would enable an increase in petroleum product exports from the United States, already the world’s largest net exporter of petroleum products. Unlike crude oil, products are not subject to export limitations or licensing requirements. While this is one possible approach to absorbing higher domestic LTO production in the absence of a relaxation of current limitations on crude exports, domestic LTO would have to be priced at a level required to encourage additional LTO runs at existing refinery units, debottlenecking, or possible additions of processing capacity.

The National Transportation Fuels Model was used to simulate a hypothetical increase in North Slope of Alaska crude oil production. The results show that the magnitude of production utilized depends in part on the ability of crude oil and refined products infrastructure in the contiguous United States to absorb and adjust to the additional supply. Decisions about expanding North Slope production can use the National Transportation Fuels Model take into account the effects on crude oil flows in the contiguous United States.

Severe maternal morbidity and comorbid risk in hospitals performing <1000 deliveries per year.

2017-02-01

While research has demonstrated increasing risk for severe maternal morbidity in the United States, risk at lower volume hospitals remains poorly characterized. More than half of all obstetric units in the United States perform <1000 deliveries per year and improving care at these hospitals may be critical to reducing risk nationwide. We sought to characterize maternal risk profiles and severe maternal morbidity at low-volume hospitals in the United States. We used data from the Nationwide Inpatient Sample to evaluate trends in severe maternal morbidity and comorbid risk during delivery hospitalizations in the United States from 1998 through 2011. Comorbid maternal risk was estimated using a comorbidity index validated for obstetric patients. Severe maternal morbidity was defined as the presence of any 1 of 15 diagnoses representative of acute organ injury and critical illness. A total of 2,300,279 deliveries occurred at hospitals with annual delivery volume <1000, representing 20% of delivery hospitalizations overall. There were 7849 cases (0.34%) of severe morbidity in low-volume hospitals and this risk increased over the course of the study from 0.25% in 1998 through 1999 to 0.49% in 2010 through 2011 (P < .01). The risk in hospitals with ≥1000 deliveries increased from 0.35-0.62% during the same time periods. The proportion of patients with the lowest comorbidity decreased, while the proportion of patients with highest comorbidity increased the most. The risk of severe morbidity increased across all women including those with low comorbidity scores. Risk for severe morbidity associated with obstetric hemorrhage, infection, hypertensive diseases of pregnancy, and medical conditions all increased during the study period. Our findings demonstrate increasing maternal risk at hospitals performing <1000 deliveries per year broadly distributed over the patient population. Rates of morbidity in centers with ≥1000 deliveries have also increased. These findings suggest that maternal safety improvements are necessary at all centers regardless of volume.

Changing patterns in the use, recycling, and material substitution of mercury in the United States

USGS Publications Warehouse

Wilburn, David R.

2013-01-01

Environmental concerns have led to numerous regulations that have dramatically decreased the reported production and use of mercury in the United States since the 1980s. Government legislation and subsequent industry actions have led to increased collection of mercury-containing materials and the recovery of mercury through recycling. Mercury emissions have been reduced and effective alternatives to mercury products have been developed for many applications. This study updates and quantifies the changes in demand, supply, use, and material flow for mercury in various sectors in the United States that have taken place since 1996. Nearly all primary mercury produced in the United States is derived as a byproduct of processing of gold and silver ore in Nevada. Since 2001, annual production of mercury from gold and silver mining in Nevada has decreased by 22 percent overall because ore from greater depths containing low grade mercury is recovered, and mercury emissions from this source have decreased by 95 percent as a result of increased regulation and improved collection and suppression technology. The distribution of consumption of mercury in the United States has changed as a result of regulation (elimination of large-scale mercury use in the paint and battery sectors), reduction by consumers (decommissioning of mercury-cell chloralkali manufacturing capacity), and technological advances (improvements in dental, lighting, and wiring sectors). Mercury use in the chloralkali sector, the leading end-use sector in the United States in 1996, has declined by 98 percent from 136 metric tons (t) in 1996 to about 0.3 t in 2010 because of increased processing and recycling efficiencies and plant closures or conversion to other technologies. As plants were closed, mercury recovered from the infrastructure of decommissioned plants has been exported, making the United States a net exporter of mercury, even though no mercury has been produced as the primary product from mines in the United States since 1992. In 1996, the three leading end-use sectors for mercury in the United States were chloralkali manufacturing (accounting for 38 percent of consumption), electrical and electronic instrumentation (13 percent of consumption), and instruments and measuring devices (11 percent of consumption). In 2010, the three leading end-use sectors were dental amalgam (accounting for between 35 and 57 percent of consumption), electrical and electronic instrumentation (29 percent of consumption), and batteries (8 percent of consumption). Mercury use in lighting is increasing because incandescent lights are being phased out in favor of mercury-containing compact fluorescent bulbs, but the demand for mercury per unit produced is small. Dental amalgam constituted the largest amount of mercury in use in the United States. One study reported about 290 t of mercury in dental amalgam was estimated to be contained in human mouths, an estimated 30 t of mercury amalgam was treated as waste, 28.5 t of mercury amalgam was released to the environment, 6 t of amalgam was recycled, and 3.5 t was treated and stored in landfills in 2009. Mercury contained in products recovered by State, municipal, or industry collection activities is recycled, but the estimated overall recycling rate is less than 10 percent. Increasingly, the U.S. mercury recycling industry has been processing a significant amount of mercury-containing material derived from foreign gold mining operations or decommissioned mercury-cell chloralkali plants. Regulation of mercury export and storage is expected to result in surplus mercury inventories in the United States. The Mercury Export Ban Act of 2008 limits elemental mercury exports for unregulated uses such as artisanal gold mining after January 1, 2013, and requires development of adequate long-term storage facilities in the United States for elemental mercury. During the past 4 years, producers and recyclers of elemental mercury have been exporting large quantities of mercury in anticipation of this regulation, but the U.S. inventory of mercury in 2010 was estimated to have exceeded 7,000 t from Government stockpiles and industry stocks. Costs attributed to long-term storage may affect the competitiveness of mercury recycling.

Factors predicting organochlorine pesticide levels in pregnant Latina women living in a United States agricultural area

Organochlorine (OC) pesticide use was restricted starting in the 1970s in developed countries and the 1980s and 1990s in developing countries. Current exposure to OC pesticides – DDT, lindane (99% pure gamma-hexachlorocyclohexane (γ-HCH)), hexachlorobenzene (HCB) – occurs on a limited basis. We measured p,p′-DDE, p,p′-DDT, o,p′-DDT, HCB, beta (β)-HCH (the most persistent isomer of technical-grade HCH) and γ-HCH in serum from 426 low-income pregnant Latina women living in an agricultural community in California. Detection frequencies were 94-100%. Median levels (ng/g-lipid) of p,p′-DDE (1,052), p,p′-DDT (13), β-HCH (37) and HCB (65) were significantly higher than U.S. population levels. Multivariate analyses of p,p′-DDE, p,p′-DDT, o,p′-DDT, β-HCH and HCB indicate that time spent living outside the United States and birthplace in an area of Mexico with recent use of OC pesticides were significant predictors of exposure. Time spent living in the United States was associated with increased serum levels of p,p′-DDE and β-HCH, but the increase for each year lived in the United States was lower than for each year lived outside the United States. There was no difference between the increase of HCB levels over time spent in or outside the United States, suggesting current and thus preventable exposure routes. However, we observed no associations between serum levels of any OC compound and current intake of saturated fat or agricultural take-home exposure risk factors. Lactation history and recent weight gain were negatively associated with serum levels of some, but not all OC compounds studied. Smoking history was borderline associated with elevated HCB levels. We observed no significant associations with body mass index. Although the weight of evidence from this study indicates that most exposure occurred prior to moving to the United States, the results for HCB indicate the possibility of ongoing exposure in this country.

In 2011, the median age of survival of patients with cystic fibrosis reported in the United States was 36.8 years, compared with 48.5 years in Canada. Direct comparison of survival estimates between national registries is challenging because of inherent differences in methodologies used, data processing techniques, and ascertainment bias. To use a standardized approach to calculate cystic fibrosis survival estimates and to explore differences between Canada and the United States. Population-based study. 42 Canadian cystic fibrosis clinics and 110 U.S. cystic fibrosis care centers. Patients followed in the Canadian Cystic Fibrosis Registry (CCFR) and U.S. Cystic Fibrosis Foundation Patient Registry (CFFPR) between 1990 and 2013. Cox proportional hazards models were used to compare survival between patients followed in the CCFR (n = 5941) and those in the CFFPR (n = 45 448). Multivariable models were used to adjust for factors known to be associated with survival. Median age of survival in patients with cystic fibrosis increased in both countries between 1990 and 2013; however, in 1995 and 2005, survival in Canada increased at a faster rate than in the United States (P < 0.001). On the basis of contemporary data from 2009 to 2013, the median age of survival in Canada was 10 years greater than in the United States (50.9 vs. 40.6 years, respectively). The adjusted risk for death was 34% lower in Canada than the United States (hazard ratio, 0.66 [95% CI, 0.54 to 0.81]). A greater proportion of patients in Canada received transplants (10.3% vs. 6.5%, respectively [standardized difference, 13.7]). Differences in survival between U.S. and Canadian patients varied according to U.S. patients' insurance status. Ascertainment bias due to missing data or nonrandom loss to follow-up might affect the results. Differences in cystic fibrosis survival between Canada and the United States persisted after adjustment for risk factors associated with survival, except for private-insurance status among U.S. patients. Differential access to transplantation, increased posttransplant survival, and differences in health care systems may, in part, explain the Canadian survival advantage.

State wildlife conservation programs provide a strong foundation for biodiversity conservation in the United States, building on state wildlife action plans. However, states may miss the species that are at the most risk at rangewide scales, and threats such as novel diseases and climate change increasingly act at regional and national levels. Regional collaborations among states and their partners have had impressive successes, and several federal programs now incorporate state priorities. However, regional collaborations are uneven across the country, and no national counterpart exists to support efforts at that scale. A national conservation-support program could fill this gap and could work across the conservation community to identify large-scale conservation needs and support efforts to meet them. By providing important information-sharing and capacity-building services, such a program would advance collaborative conservation among the states and their partners, thus increasing both the effectiveness and the efficiency of conservation in the United States.

In 2009, an estimated 3590 new heterosexually acquired HIV infections occurred in males in the United States. Three randomized controlled trials demonstrated that male circumcision decreased a man's risk for HIV acquisition through heterosexual sex. We describe circumcision prevalence in US males and determine circumcision prevalence among males potentially at increased risk for heterosexually acquired HIV infection. We estimated circumcision prevalence among men and boys aged 14 to 59 years using data from the National Health and Nutrition Examination Surveys 2005-2010. We defined men and boys with 2 or more female partners in the last year as potentially at increased risk for heterosexually acquired HIV infection. Estimated circumcision prevalence was 80.5%. Prevalence varied significantly by year of birth, race/ethnicity, health insurance type, and family income. Circumcision prevalence among men and boys reporting 2 or more female partners in the last year was 80.4%, which corresponded to an estimated 3.5 million uncircumcised men and boys potentially at increased risk for heterosexually acquired HIV infection. Of these men and boys, 48.3% lacked health insurance. Circumcision prevalence in the United States differs by demographic group, and half of uncircumcised men and boys potentially at increased risk for heterosexually acquired HIV are uninsured. These data could inform recommendations and cost analyses concerning circumcision in the United States.

Achieving climate connectivity in a fragmented landscape

The contiguous United States contains a disconnected patchwork of natural lands. This fragmentation by human activities limits species’ ability to track suitable climates as they rapidly shift. However, most models that project species movement needs have not examined where fragmentation will limit those movements. Here, we quantify climate connectivity, the capacity of landscape configuration to allow species movement in the face of dynamically shifting climate. Using this metric, we assess to what extent habitat fragmentation will limit species movements in response to climate change. We then evaluate how creating corridors to promote climate connectivity could potentially mitigate these restrictions, and we assess where strategies to increase connectivity will be most beneficial. By analyzing fragmentation patterns across the contiguous United States, we demonstrate that only 41% of natural land area retains enough connectivity to allow plants and animals to maintain climatic parity as the climate warms. In the eastern United States, less than 2% of natural area is sufficiently connected. Introducing corridors to facilitate movement through human-dominated regions increases the percentage of climatically connected natural area to 65%, with the most impactful gains in low-elevation regions, particularly in the southeastern United States. These climate connectivity analyses allow ecologists and conservation practitioners to determine the most effective regions for increasing connectivity. More importantly, our findings demonstrate that increasing climate connectivity is critical for allowing species to track rapidly changing climates, reconfiguring habitats to promote access to suitable climates.

Motor unit recruitment and firing rate in medial gastrocnemius muscles during external perturbations in standing in humans.

Pollock, C L; Ivanova, T D; Hunt, M A; Garland, S J

2014-10-01

There is limited investigation of the interaction between motor unit recruitment and rate coding for modulating force during standing or responding to external perturbations. Fifty-seven motor units were recorded from the medial gastrocnemius muscle with intramuscular electrodes in response to external perturbations in standing. Anteriorly directed perturbations were generated by applying loads in 0.45-kg increments at the pelvis every 25-40 s until 2.25 kg was maintained. Motor unit firing rate was calculated for the initial recruitment load and all subsequent loads during two epochs: 1) dynamic response to perturbation directly following each load drop and 2) maintenance of steady state between perturbations. Joint kinematics and surface electromyography (EMG) from lower extremities and force platform measurements were assessed. Application of the external loads resulted in a significant forward progression of the anterior-posterior center of pressure (AP COP) that was accompanied by modest changes in joint angles (<3°). Surface EMG increased more in medial gastrocnemius than in the other recorded muscles. At initial recruitment, motor unit firing rate immediately after the load drop was significantly lower than during subsequent load drops or during the steady state at the same load. There was a modest increase in motor unit firing rate immediately after the load drop on subsequent load drops associated with regaining balance. There was no effect of maintaining balance with increased load and forward progression of the AP COP on steady-state motor unit firing rate. The medial gastrocnemius utilized primarily motor unit recruitment to achieve the increased levels of activation necessary to maintain standing in the presence of external loads.

Trypanosoma cruzi and Chagas' Disease in the United States

PubMed Central

Bern, Caryn; Kjos, Sonia; Yabsley, Michael J.; Montgomery, Susan P.

2011-01-01

Summary: Chagas' disease is caused by the protozoan parasite Trypanosoma cruzi and causes potentially life-threatening disease of the heart and gastrointestinal tract. The southern half of the United States contains enzootic cycles of T. cruzi, involving 11 recognized triatomine vector species. The greatest vector diversity and density occur in the western United States, where woodrats are the most common reservoir; other rodents, raccoons, skunks, and coyotes are also infected with T. cruzi. In the eastern United States, the prevalence of T. cruzi is highest in raccoons, opossums, armadillos, and skunks. A total of 7 autochthonous vector-borne human infections have been reported in Texas, California, Tennessee, and Louisiana; many others are thought to go unrecognized. Nevertheless, most T. cruzi-infected individuals in the United States are immigrants from areas of endemicity in Latin America. Seven transfusion-associated and 6 organ donor-derived T. cruzi infections have been documented in the United States and Canada. As improved control of vector- and blood-borne T. cruzi transmission decreases the burden in countries where the disease is historically endemic and imported Chagas' disease is increasingly recognized outside Latin America, the United States can play an important role in addressing the altered epidemiology of Chagas' disease in the 21st century.

Responses of stream nitrate and DOC loadings to hydrological forcing and climate change in an upland forest of the northeastern United States

2009-06-01

In coming decades, higher annual temperatures, increased growing season length, and increased dormant season precipitation are expected across the northeastern United States in response to anthropogenic forcing of global climate. We synthesized long-term stream hydrochemical data from the Sleepers River Research Watershed in Vermont, United States, to explore the relationship of catchment wetness to stream nitrate and DOC loadings. We modeled changes in growing season length and precipitation patterns to simulate future climate scenarios and to assess how stream nutrient loadings respond to climate change. Model results for the 2070-2099 time period suggest that stream nutrient loadings during both the dormant and growing seasons will respond to climate change. During a warmer climate, growing season stream fluxes (runoff +20%, nitrate +57%, and DOC +58%) increase as more precipitation (+28%) and quick flow (+39%) occur during a longer growing season (+43 days). During the dormant season, stream water and nutrient loadings decrease. Net annual stream runoff (+8%) and DOC loading (+9%) increases are commensurate with the magnitude of the average increase of net annual precipitation (+7%). Net annual stream water and DOC loadings are primarily affected by increased dormant season precipitation. In contrast, decreased annual loading of stream nitrate (-2%) reflects a larger effect of growing season controls on stream nitrate and the effects of lengthened growing seasons in a warmer climate. Our findings suggest that leaching of nitrate and DOC from catchment soils will be affected by anthropogenic climate forcing, thereby affecting the timing and magnitude of annual stream loadings in the northeastern United States.

Educational gradients in psychotropic medication use among older adults in Costa Rica and the United States.

2014-10-01

The relationship of education, psychiatric diagnoses, and use of psychotropic medication has been explored in the United States, but little is known about this relationship in poorer countries, despite the high burden of mental illness in these countries. This study estimated educational gradients in diagnosis and psychotropic drug use in the United States and Costa Rica, a middle-income country with universal health insurance. Analyses were conducted by using data of older adults (≥60) from the 2005 U.S. Medical Expenditure Panel Survey (N=4,788) and the 2005 Costa Rican Longevity and Healthy Aging Study (N=2,827). Logistic regressions examined the effect of education level (low, medium, or high) and urban residence on the rates of self-reported mental health diagnoses, screening diagnosis, and psychotropic medication use with and without an associated psychiatric diagnosis. Rates of self-reported diagnoses were lower in the United States (12%) than in Costa Rica (20%), possibly reflecting differences in survey wording. In both countries, the odds of having depression were significantly lower among persons with high education. In Costa Rica, use of psychotropic medication among persons with self-reported diagnoses increased by education level. The educational gradients in medication use were different in the United States and Costa Rica, and stigma and access to care in these countries may play an important role in these differences, although type of insurance did not affect educational gradients in the United States. These analyses increase the evidence of the role of education in use of the health care system.

2014-01-01

Purpose Evaluate retrospectively whether findings from the Cornea Donor Study (CDS) led to changes in the transplantation of corneas from older donors. Methods United States eye banks provided complete data on donor age and placement (domestic or international) for 86,273 corneas from 1998 to 2009. The data were analyzed by 3 time periods: preceding CDS (1998–1999), during CDS (2000–2007) and after publication of CDS 5 year results (2008–2009), and separately for corneas placed within vs. outside the United States. Results For corneal tissues transplanted in the United States, the percentage of donors ≥66 years old increased from 19% before CDS to 21% during CDS and 25% after CDS (p<0.001). Corresponding median (25th-75th percentile) donor ages were 53 (39–63), 54 (41–64) and 57 (46–66), respectively (p<0.001). The opposite trend was observed for corneas distributed outside the United States with the percentage of donors ≥66 years old decreasing from 56% to 42% to 34%, respectively. Donor age trends over time varied by eye bank. Conclusions There was a modest overall increase in the donor age of corneas transplanted in the United States from 1998 to 2009, but the retrospective nature of the study limits our ability to attribute this change to the CDS. The modest increases in the donor age of corneas transplanted is a positive finding, but wider acceptance of older corneal donor tissue should be encouraged based on the five-year evidence generated by the CDS.

To evaluate the incidence of acute mastoiditis in children in the United States over the years 1997 through 2006 and to explore possible explanations for the conflicting conclusions of recent studies of this topic. Comparison of periodic incidence over a decade. Academic and community, general, and pediatric specialty hospitals in the United States. Children younger than 18 years in the United States treated and discharged with a diagnosis of acute mastoiditis during the years 1997 through 2006. To compare true incidence of acute mastoiditis in the pediatric population of the United States, data from Healthcare Costs and Utilization Project-Kids' Inpatient Database (HCUP-KID) was examined for nationally weighted estimates of hospital discharges, demographics (age and sex), hospital characteristics, and insurance characteristics. No significant change was found in the incidence of acute mastoiditis over the study period (from 1.88 to 1.62 per 100,000 person-years) (regression coefficient -0.024 [95% CI, -0.110 to 0.024]) (P = .37). Children admitted with acute mastoiditis had an increased odds of presenting to a teaching hospital (odds ratio [OR], 1.38 [95% CI, 1.31-1.45]) (P < .001), a children's hospital (OR, 1.08 [95% CI, 1.03-1.14]) (P = .001), and to a metropolitan location (OR, 1.10 [95% CI, 1.02-1.18]) (P = .016) over calendar time. The incidence of acute mastoiditis in the United States is not increasing. The changes in hospital factors identified over the course of this study may explain the perception of increased incidence identified in studies that have not used population-level data.

Ecosystem carbon (C) uptake is determined largely by C residence times and increases in net primary production (NPP). Therefore, evaluation of C uptake at a regional scale requires knowledge on spatial patterns of both residence times and NPP increases. In this study, we first applied an inverse modeling method to estimate spatial patterns of C residence times in the conterminous United States. Then we combined the spatial patterns of estimated residence times with a NPP change trend to assess the spatial patterns of regional C uptake in the United States. The inverse analysis was done by using the genetic algorithm and was based on 12 observed data sets of C pools and fluxes. Residence times were estimated by minimizing the total deviation between modeled and observed values. Our results showed that the estimated C residence times were highly heterogeneous over the conterminous United States, with most of the regions having values between 15 and 65 years; and the averaged C residence time was 46 years. The estimated C uptake for the whole conterminous United States was 0.15 P g C a-1. Large portions of the taken C were stored in soil for grassland and cropland (47-70%) but in plant pools for forests and woodlands (73-82%). The proportion of C uptake in soil was found to be determined primarily by C residence times and be independent of the magnitude of NPP increase. Therefore, accurate estimation of spatial patterns of C residence times is crucial for the evaluation of terrestrial ecosystem C uptake.

Earthquake damage is often increased due to local ground-motion amplification caused by soft soils, thick basin sediments, topographic effects, and liquefaction. A critical factor contributing to the assessment of seismic hazard is detailed information on local site response. In order to address and quantify the site response at seismograph stations in the eastern United States, we investigate the regional spatial variation of horizontal:vertical spectral ratios (HVSR) using ambient noise recorded at permanent regional and national network stations as well as temporary seismic stations deployed in order to record aftershocks of the 2011 Mineral, Virginia, earthquake. We compare the HVSR peak frequency to surface measurements of the shear-wave seismic velocity to 30 m depth (Vs30) at 21 seismograph stations in the eastern United States and find that HVSR peak frequency increases with increasing Vs30. We use this relationship to estimate the National Earthquake Hazards Reduction Program soil class at 218 ANSS (Advanced National Seismic System), GSN (Global Seismographic Network), and RSN (Regional Seismograph Networks) locations in the eastern United States, and suggest that this seismic station–based HVSR proxy could potentially be used to calibrate other site response characterization methods commonly used to estimate shaking hazard.

Background: Researchers in tobacco control are concerned about the increasing prevalence of waterpipe smoking in the United States, which may pose similar risks as cigarette smoking. This review explores the prevalence of waterpipe smoking in the United States as well as the shortcomings of current U.S. policy for waterpipe control and regulation. Methods: Researchers conducted a literature review for waterpipe articles dated between 2004 and 2015 using five online databases: MEDLINE, CINHAHL, ScienceDirect, PMC, and Cochrane Library. Results: To date, few studies have explored the marketing and regulation of waterpipe smoking in the U.S., which has increased in the last ten years, especially among women, adolescents, and young adults. Data indicate that the majority of waterpipe smokers are unaware of the potential risks of use. In addition, current tobacco control policies do not address waterpipe smoking, enabling tobacco companies to readily market and sell waterpipe products to young adults, who are at risk for becoming lifelong smokers. Conclusion: Policy makers in the area of public health need to update existing tobacco regulations to include waterpipe smoking. Similarly, public health researchers should develop public health campaigns and interventions to address the increasing rates of waterpipe smoking in the United States. PMID:26110330

This paper compares mothers’ experience of having children with more than one partner in two liberal welfare regimes (the United States and Australia) and two social democratic regimes (Sweden and Norway). We use survey-based union and birth histories in Australia and the United States and data from national population registers in Norway and Sweden to estimate the likelihood of experiencing childbearing across partnerships at any point in the childbearing career. We find that births with new partners constitute a substantial proportion of all births in each country we study. Despite quite different arrangements for social welfare, the determinants of childbearing across partnerships are very similar. Women who had their first birth at a very young age or who are less well educated are most likely to have children with different partners. Socioeconomic differentials in childbearing across partnerships appeared to be stronger in the United States, but not in comparison to differentials in childbearing in the same union. Thus, no strong evidence was found for a steeper educational gradient in the liberal as opposed to social democratic welfare regimes. The risk of childbearing across partnerships increased dramatically in all countries from the 1980s to the 2000s, and the educational differential also increased; again, however, the increases were not associated with welfare regime.

Death rates by specific causes vary across the 50 states and the District of Columbia.* Information on differences in rates for the leading causes of death among states might help state health officials determine prevention goals, priorities, and strategies. CDC analyzed National Vital Statistics System data to provide national and state-specific estimates of potentially preventable deaths among the five leading causes of death in 2014 and compared these estimates with estimates previously published for 2010. Compared with 2010, the estimated number of potentially preventable deaths changed (supplemental material at https://stacks.cdc.gov/view/cdc/42472); cancer deaths decreased 25% (from 84,443 to 63,209), stroke deaths decreased 11% (from 16,973 to 15,175), heart disease deaths decreased 4% (from 91,757 to 87,950), chronic lower respiratory disease (CLRD) (e.g., asthma, bronchitis, and emphysema) deaths increased 1% (from 28,831 to 29,232), and deaths from unintentional injuries increased 23% (from 36,836 to 45,331). A better understanding of progress made in reducing potentially preventable deaths in the United States might inform state and regional efforts targeting the prevention of premature deaths from the five leading causes in the United States.

Human activity in the last century has increased nitrogen (N) deposition to a level that has caused or is likely to cause alterations to the structure and function of many ecosystems across the United States. We synthesized current research relating atmospheric N deposition to effects on terrestrial and freshwater ecosystems in the United States, and estimated associated empirical critical loads of N for several receptors: freshwater diatoms, mycorrhizal fungi, lichens, bryophytes, herbaceous plants, shrubs, and trees. Biogeochemical responses included increased N mineralization and nitrification, increased gaseous N losses, and increased N leaching. Individual species, population, and community responses included increased tissue N, physiological and nutrient imbalances, increased growth, altered root-shoot ratios, increased susceptibility to secondary stresses, altered fire regime, shifts in competitive interactions and community composition, changes in species richness and other measures of biodiversity, and increases in invasive species. The range of critical loads of nutrient N reported for U.S. ecoregions, inland surface waters, and freshwater wetlands is 1–39 kg N ha−1 yr−1, spanning the range of N deposition observed over most of the country. The empirical critical loads of N tend to increase in the following sequence: diatoms, lichens and bryophytes, mycorrhizal fungi, herbaceous plants and shrubs, trees.

Objective Although the number of intensive care beds in the United States is increasing, little is known about the hospitals responsible for this growth. We sought to better characterize national growth in intensive care beds by identifying hospital-level factors associated with increasing numbers of intensive care beds over time. Design We performed a repeated-measures time series analysis of hospital-level intensive care bed supply using data from Centers for Medicare and Medicaid Services. Setting All United States acute care hospitals with adult intensive care beds over the years 1996 to 2011. Measurements & Main Results We described the number of beds, teaching status, ownership, intensive care occupancy and urbanicity for each hospital in each year of the study. We then examined the relationship between increasing intensive care beds and these characteristics, controlling for other factors. The study included 4,457 hospitals and 55,865 hospital-years. Overall, the majority of intensive care bed growth occurred in teaching hospitals (net +13,471 beds, 72.1% of total growth), hospitals with 250 or more beds (net +18,327 beds, 91.8% of total growth) and hospitals in the highest quartile of occupancy (net +10,157 beds, 54.0% of total growth). In a longitudinal multivariable model, larger hospital size, teaching status, and high intensive care occupancy were associated with subsequent-year growth. Furthermore, the effects of hospital size and teaching status were modified by occupancy: the greatest odds of increasing intensive care unit beds were in hospitals with 500 or more beds in the highest quartile of occupancy (adjusted OR: 18.9; 95% CI: 14.0 – 25.5; p<0.01) and large teaching hospitals in the highest quartile of occupancy (adjusted OR: 7.3; 95% CI: 5.3 – 9.9; p<0.01). Conclusions Increasingly, intensive care bed expansion in the United States is occurring in larger hospitals and teaching centers, particularly following a year with high intensive care unit occupancy.

Major lower extremity (MLE) amputation is a common procedure that results in a profound change in a patient's life. We sought to determine the association between social support and outcomes after amputation. We hypothesized that patients with greater social support will have better post amputation outcomes. From November 2011 to May 2013, we conducted a cross-sectional, observational, multicenter study. Social integration was measured by the social integration subset of the Short Form Craig Handicap Assessment and Reporting Technique. Systemic social support was assessed by comparing a United States and Tanzanian population. Walking function was measured using the 6-minute walk test and quality of life (QoL) was measured using the EuroQol-5D. We recruited 102 MLE amputees. Sixty-three patients were enrolled in the United States with a mean age of 58.0. Forty-two (67%) were male. Patients with low social integration were more likely to be unable to ambulate (no walk 39% vs slow walk 23% vs fast walk 10%; P = .01) and those with high social integration were more likely to be fast walkers (no walk 10% vs slow walk 59% vs fast walk 74%; P = .01). This relationship persisted in a multivariable analysis. Increasing social integration scores were also positively associated with increasing QoL scores in a multivariable analysis (β, .002; standard error, 0.0008; P = .02). In comparing the United States population with the Tanzanian cohort (39 subjects), there were no differences between functional or QoL outcomes in the systemic social support analysis. In the United States population, increased social integration is associated with both improved function and QoL outcomes among MLE amputees. Systemic social support, as measured by comparing the United States population with a Tanzanian population, was not associated with improved function or QoL outcomes. In the United States, steps should be taken to identify and aid amputees with poor social integration. Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

Introduction In recent years, self-reported cigarette smoking has declined among youth and adults, while electronic cigarette (e-cigarette) use has increased. However, sales trends for these products are less certain. This study assessed national and state patterns of U.S. cigarette and e-cigarette unit sales. Methods Trends in cigarette and e-cigarette unit sales were analyzed using retail scanner data from September 25, 2011 through January 9, 2016 for: (1) convenience stores; and (2) all other outlets combined, including supermarkets, mass merchandisers, drug, dollar, and club stores, and military commissaries (online, tobacco-only, and “vape“ shops were not available). Data by store type were available for the total contiguous U.S. and 29 states; combined data were available for the remaining states, except Alaska, Hawaii, and DC. Results During 2011–2015, cigarette sales exhibited a small, significant decrease; however, positive year-over-year growth occurred in convenience stores throughout most of 2015. E-cigarette unit sales significantly increased during 2011–2015, but year-over-year growth slowed and was occasionally negative. Cigarette unit sales exceeded e-cigarettes by 64:1 during the last 4-week period. During 2014–2015, cigarette sales increases occurred in 15 of 48 assessed states; e-cigarette sales increased in 18 states. Conclusions Despite overall declines during 2011–2015, cigarette sales in 2015 grew for the first time in a decade. E-cigarette sales growth was positive, but slowed over the study period in assessed stores. Cigarette sales continued to exceed e-cigarette sales, reinforcing the importance of efforts to reduce the appeal and accessibility of cigarettes and other combusted tobacco products. PMID:28285828

The Growing Public Health Challenges of Exposure to Ultraviolet Radiation From Use of Indoor Tanning Devices in the United States.

2015-08-01

Ultraviolet radiation is recognized as a human carcinogen by the International Agency for Research on Cancer, the world's authority on cancer research. In particular, exposure to ultraviolet radiation can lead to melanoma of the skin, which is the deadliest form of skin cancer in the United States. Yet despite the significant public health burden that is associated with skin cancer in the United States, each year over a million Americans engage in indoor tanning where exposure to artificial ultraviolet radiation occurs. In this article, we argue for an immediate ban on the use of commercial indoor tanning by minors and, based on international precedents, the phasing out of all commercial tanning operations in the United States. We consider the use of indoor tanning devices in the United States, epidemiological data on indoor tanning devices and cancer, regulation of tanning devices, and scientific evidence for increased government intervention. © The Author(s) 2015.

Despite decades of experience treating heroin or prescription opioid dependence with methadone or buprenorphine--two forms of opioid substitution therapy--gaps remain between current practices and evidence-based standards in both Canada and the United States. This is largely because of regulatory constraints and pervasive suboptimal clinical practices. Fewer than 10 percent of all people dependent on opioids in the United States are receiving substitution treatment, although the proportion may increase with expanded health insurance coverage as a result of the Affordable Care Act. In light of the accumulated evidence, we recommend eliminating restrictions on office-based methadone prescribing in the United States; reducing financial barriers to treatment, such as varying levels of copayment in Canada and the United States; reducing reliance on less effective and potentially unsafe opioid detoxification; and evaluating and creating mechanisms to integrate emerging treatments. Taking these steps can greatly reduce the harms of opioid dependence by maximizing the individual and public health benefits of treatment.

2013-01-01

BACKGROUND AND OBJECTIVE: The American Academy of Pediatrics recommends all preterm infants receive human milk. The objective of this study was to describe the use of human milk in advanced care neonatal units of US maternity hospitals. METHODS: We used Centers for Disease Control and Prevention’s national Maternity Practices in Infant Nutrition and Care survey from 2007, 2009, and 2011 to analyze 2 questions to describe the prevalence of US advanced care (special/level 2 or intensive/level 3) neonatal units routinely providing human milk to infants, and the use of any donor milk in these units. RESULTS: In 2011, 30.8% of maternity hospitals reported that most infants (≥90%) were routinely provided human milk in advanced care units, compared with 26.7% in 2009 and 21.2% in 2007 (trend P < .001). States in the Northwest and Northeast had a higher prevalence of hospitals routinely providing human milk to ≥90% of infants in advanced care units. In 2011, 22.0% of maternity hospitals providing advanced care used banked donor milk, compared with 14.4% in 2009 and 11.5% in 2007 (trend P < .001). Most of this increase occurred in intensive care units (25.1% 2007 vs 45.2% 2011; trend P < .001). There was substantial geographic variation in the prevalence of advanced care units using donor milk; generally the prevalence was higher in the West and in states with a milk bank in the state or a neighboring state. CONCLUSIONS: The use of human milk in US advanced care neonatal units is increasing; however, only one-third of these units are routinely providing human milk to most infants. PMID:23669517

Widespread increase of tree mortality rates in the Western United States

Persistent changes in tree mortality rates can alter forest structure, composition, and ecosystem services such as carbon sequestration. Our analyses of longitudinal data from unmanaged old forests in the western United States showed that background (noncatastrophic) mortality rates have increased rapidly in recent decades, with doubling periods ranging from 17 to 29 years among regions. Increases were also pervasive across elevations, tree sizes, dominant genera, and past fire histories. Forest density and basal area declined slightly, which suggests that increasing mortality was not caused by endogenous increases in competition. Because mortality increased in small trees, the overall increase in mortality rates cannot be attributed solely to aging of large trees. Regional warming and consequent increases in water deficits are likely contributors to the increases in tree mortality rates.

The feature of the stress state of the supports of the contact networks is the presence of a joint of pipes of different diameters, the ultimate state of which is determined, as a rule, the strength of the weld. The proposed unit allows to increase the reliability and strength of the connection and also exclude the presence of a weld bead on the outer surface of the pipe of smaller diameter in the place of its attachment to the upper end of the support ring.

Integrated health system for chronic disease management: lessons learned from France.

Stuart, Mary; Weinrich, Michael

2004-02-01

Rated number one in overall health system performance by the World Health Organization, the French spend less than half the amount on annual health care per capita that the United States spends. One contributing factor may be the attention given to chronic care. Since the mid-1900s, the French have developed regional community-based specialty systems for patients with chronic respiratory insufficiency or failure. COPD is the major cause of respiratory failure, the fourth leading cause of death in the United States, and its prevalence is increasing. Despite the clinical success of home mechanical ventilation and the potential for cost savings, providing such services in the United States remains a challenge. Lessons from France can inform the development of cost-effective chronic care models in the United States In this article, we review the French experience in the context of the United States Supreme Court's Olmstead decision, mandating that people in "more restrictive settings" such as nursing homes be offered community-based supports. We suggest that regional demonstration projects for patients with chronic respiratory failure or insufficiency can provide an important step in the development of effective chronic care systems in the United States

Effects of El Niño on Summertime Ozone Air Quality in the Eastern United States

We investigate the effect of El Niño on maximum daily 8 h average surface ozone over the eastern United States in summer during 1980-2016. El Niño can influence the extratropical climate through the propagation of stationary waves, leading to (1) reduced transport of moist, clean air into the middle and southern Atlantic states and greater subsidence, reduced precipitation, and increased surface solar radiation in this region, as well as (2) intensified southerly flow into the south central states, which here enhances flux of moist and clean air. As a result, each standard deviation increase in the Niño 1 + 2 index is associated with an increase of 1-2 ppbv ozone in the Atlantic states and a decrease of 0.5-2 ppbv ozone in the south central states. These influences can be predicted 4 months in advance. We show that U.S. summertime ozone responds differently to eastern-type El Niño events compared to central-type events.

Bibliometric indicators are used to assess research performance. The goal of this study was to explore publication output to construct a picture of orthopedics that may be beneficial to researchers and orthopedic specialists. All orthopedics articles published in 61 journals from 2000 to 2011 were retrieved from the Science Citation Index Expanded database. The numbers of articles, citations, authors, institutions, and journals were analyzed and subjected to quantitative and qualitative comparisons. The number of published orthopedics articles increased between 2000 and 2011. Articles published by authors from the United States always ranked first in number, although the United States' share is decreasing in the world literature. Authors from the United States published the most-cited articles and the most articles in journals with top-10 impact factors; moreover, the United States also had the greatest share of experts and highly ranked institutions. The United Kingdom, Germany, and Japan were always within the world's top 4 in terms of numbers of articles and citations. The shares of Germany, South Korea, and China among total orthopedics articles increased, especially that of China. In 2011, China ranked the fifth in the world, with its world share increasing from 0.64% in 2000 to 5.05% in 2011. However, China lags behind in average citations per article, top research institutions, and most prolific authors. According to the total citations per article, the University of Pittsburgh, Harvard University, and the Hospital for Special Surgery were the most prolific institutions.

Retrospective review is a key to designing effective food safety measures. The analysis examines trends in the reported incidence of illness due to bacterial pathogens commonly transmitted by food in the United States during 1996-2013 with and without specifying a model form for trend. The findings indicate early declines in reported incidence followed by a period of no significant trend for Campylobacter, Listeria, Shiga toxin-producing Escherichia coli O157, and Yersinia. The results are inconclusive about whether there is no trend or an increasing trend for Salmonella. While Shigella exhibits a continuous decline, Vibrio exhibits a continuous increase. Overall, the findings indicate a lack of evidence for continuous reduction in illness due to bacterial pathogens commonly transmitted by food in the United States during 1996-2013. © 2015 Society for Risk Analysis.

The earliest years are critical in terms of future cognitive and emotional development and early health outcomes, and have long-lasting consequences on future health. In this article child poverty in the United States is compared with a set of other developed countries. To the surprise of few, results show that child poverty is high in the United States. But why is poverty so much higher in the United States than in other rich nations? Among child poverty drivers, household composition and parent's labor market participation matter a great deal. But these are not insurmountable problems. Many of these disadvantages can be overcome by appropriate public policies. For example, single mothers have a very high probability of poverty in the United States, but this is not the case in other countries where the provision of work support increases mothers' labor earnings and together with strong public cash support effectively reduces child poverty. In this article we focus on the role and design of public expenditure to understand the functioning of the different national systems and highlight ways for improvements to reduce child poverty in the United States. We compare relative child poverty in the United States with poverty in a set of selected countries. The takeaway is that the United States underinvests in its children and their families and in so doing this leads to high child poverty and poor health and educational outcomes. If a nation like the United States wants to decrease poverty and improve health and life chances for poor children, it must support parental employment and incomes, and invest in children's futures as do other similar nations with less child poverty.

State cigarette minimum price laws - United States, 2009.

PubMed

2010-04-09

Cigarette price increases reduce the demand for cigarettes and thereby reduce smoking prevalence, cigarette consumption, and youth initiation of smoking. Excise tax increases are the most effective government intervention to increase the price of cigarettes, but cigarette manufacturers use trade discounts, coupons, and other promotions to counteract the effects of these tax increases and appeal to price-sensitive smokers. State cigarette minimum price laws, initiated by states in the 1940s and 1950s to protect tobacco retailers from predatory business practices, typically require a minimum percentage markup to be added to the wholesale and/or retail price. If a statute prohibits trade discounts from the minimum price calculation, these laws have the potential to counteract discounting by cigarette manufacturers. To assess the status of cigarette minimum price laws in the United States, CDC surveyed state statutes and identified those states with minimum price laws in effect as of December 31, 2009. This report summarizes the results of that survey, which determined that 25 states had minimum price laws for cigarettes (median wholesale markup: 4.00%; median retail markup: 8.00%), and seven of those states also expressly prohibited the use of trade discounts in the minimum retail price calculation. Minimum price laws can help prevent trade discounting from eroding the positive effects of state excise tax increases and higher cigarette prices on public health.

This study aims to examine survival for gastric lymphomas and its main subtypes, mucosa-associated lymphoid tissue lymphoma (MALT), and diffuse large B-cell lymphoma (DLBCL), in Germany and in the United States. Data for patients diagnosed in 1997-2010 were used from 10 population-based German cancer registries and compared to the data from the US Surveillance, Epidemiology and End Results (SEER) 13 registries database. Patients age 15-74 diagnosed with gastric lymphomas were included in the analysis. Period analysis and modeled period analysis were used to estimate 5-year and 10-year relative survival (RS) in 2002-2010 and survival trends from 2002-2004 to 2008-2010. Overall, the database included 1534 and 2688 patients diagnosed with gastric lymphoma in 1997-2010 in Germany and in the United States, respectively. Survival was substantially higher for MALT (5-year and 10-year RS: 89.0% and 80.9% in Germany, 93.8% and 86.8% in the United States) than for DLBCL (67.5% and 59.2% in Germany, and 65.3% and 54.7% in the United States) in 2002-2010. Survival was slightly higher among female patients and decreased by age for gastric lymphomas combined and its main subtypes. A slight, nonsignificant, increase in the 5-year RS for gastric lymphomas combined was observed in Germany and the United States, with increases in 5-year RS between 2002-2004 and 2008-2010 from 77.1% to 81.0% and from 77.3% to 82.0%, respectively. Five-year RS of MALT exceeded 90% in 2008-2010 in both countries. Five-year RS of MALT meanwhile exceeds 90% in both Germany and the United States, but DLBCL has remained below 70% in both countries. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

To assess the attitudes of medical students in India about participating in graduate medical education in the United States and other countries and in subsequent clinical practice in those countries. A total of 240 students who were attending their final year at two medical schools in Bangalore, India, were surveyed during 2004. Surveys were completed by 166 (69%) of the students. Among the responding students, 98 (59%) thought of leaving India for further training abroad. Of those who wished to leave, 41 (42%) preferred the United States, 42 (43%) preferred the United Kingdom, and 9 (9%) preferred Canada, Australia or New Zealand. Only two students preferred the Middle East. Most who favored training in the United States indicated that they intended to remain after training, whereas fewer than 20% of those who favored training in the United Kingdom had such intentions. While more than 60% perceived greater professional opportunities in the United States than in India, approximately 75% were concerned that the United States had become less welcoming after the terrorist attacks of 9/11, and similar numbers were concerned about the examination administered by the Educational Commission on Foreign Medical Graduates. Conversely, the majority of respondents felt that opportunities for physicians in India were improving. While optimism about future medical careers in India is increasing, the interest of Indian medical students in training and subsequently practicing in the United States remains high.

Increasing Anthropogenic Emissions in China Offset Air Quality Policy Efforts in Western United States: A Satellite and Modelling Perspective

NASA Astrophysics Data System (ADS)

Boersma, F. F.; Verstraeten, W. W.; Williams, J. E.; Neu, J. L.; Bowman, K. W.; Worden, J.

2014-12-01

Tropospheric ozone is an important greenhouse gas and a global air pollutant originating from photo-chemical oxidation of ozone precursors in the presence of NOX. Eastern Asia has the fastest growing anthropogenic emissions in the world, possibly affecting both the pollution in the local troposphere as well as in the trans-Pacific region. Local measurements over Asia show that tropospheric ozone has increased by 1 to 3% per year since the start of the millennium. This increase is often invoked to explain positive ozone trends observed in western United States, but to date there is no unambiguous evidence showing that enhanced Asian pollution is responsible for these trends. Here we interpret satellite measurements of tropospheric ozone and its precursor nitrate dioxide from the Aura Tropospheric Emission Spectrometer (TES) and Ozone Monitoring Instrument (OMI) using the TM5 global chemistry-transport model to directly show that tropospheric ozone over China has increased by ~10% from 2005-2010 in response to both a ~15% rise in Chinese emissions and an increased downward ozone transport from the stratosphere. What is more, we demonstrate that Chinese export of ozone and its precursors have offset one-third of the reduction in free tropospheric ozone over the western United States that should have occurred during 2005-2010 via emissions reductions associated with air quality policies in the United States. The issue of export and long-range transport of pollution from other countries indicates that global efforts may be required to address both the global as well as the regional air quality and climate change.

The United States is experiencing an epidemic of drug overdose (poisoning) deaths. Since 2000, the rate of deaths from drug overdoses has increased 137%, including a 200% increase in the rate of overdose deaths involving opioids (opioid pain relievers and heroin). CDC analyzed recent multiple cause-of-death mortality data to examine current trends and characteristics of drug overdose deaths, including the types of opioids associated with drug overdose deaths. During 2014, a total of 47,055 drug overdose deaths occurred in the United States, representing a 1-year increase of 6.5%, from 13.8 per 100,000 persons in 2013 to 14.7 per 100,000 persons in 2014. The rate of drug overdose deaths increased significantly for both sexes, persons aged 25-44 years and ≥55 years, non-Hispanic whites and non-Hispanic blacks, and in the Northeastern, Midwestern, and Southern regions of the United States. Rates of opioid overdose deaths also increased significantly, from 7.9 per 100,000 in 2013 to 9.0 per 100,000 in 2014, a 14% increase. Historically, CDC has programmatically characterized all opioid pain reliever deaths (natural and semisynthetic opioids, methadone, and other synthetic opioids) as "prescription" opioid overdoses (1). Between 2013 and 2014, the age-adjusted rate of death involving methadone remained unchanged; however, the age-adjusted rate of death involving natural and semisynthetic opioid pain relievers, heroin, and synthetic opioids, other than methadone (e.g., fentanyl) increased 9%, 26%, and 80%, respectively. The sharp increase in deaths involving synthetic opioids, other than methadone, in 2014 coincided with law enforcement reports of increased availability of illicitly manufactured fentanyl, a synthetic opioid; however, illicitly manufactured fentanyl cannot be distinguished from prescription fentanyl in death certificate data. These findings indicate that the opioid overdose epidemic is worsening. There is a need for continued action to prevent opioid abuse, dependence, and death, improve treatment capacity for opioid use disorders, and reduce the supply of illicit opioids, particularly heroin and illicit fentanyl.

In coming decades, higher annual temperatures, increased growing season length, and increased dormant season precipitation are expected across the northeastern United States in response to anthropogenic forcing of global climate. We synthesized long-term stream hydrochemical data from the Sleepers River Research Watershed in Vermont, United States, to explore the relationship of catchment wetness to stream nitrate and DOC loadings. We modeled changes in growing season length and precipitation patterns to simulate future climate scenarios and to assess how stream nutrient loadings respond to climate change. Model results for the 2070-2099 time period suggest that stream nutrient loadings during both the dormant and growing seasons will respond to climate change. During a warmer climate, growing season stream fluxes (runoff+20%, nitrate +57%, and DOC +58%) increase as more precipitation (+28%) and quick flow (+39%) occur during a longer growing season (+43 days). During the dormant season, stream water and nutrient loadings decrease. Net annual stream runoff (+8%) and DOC loading (+9%) increases are commensurate with the magnitude of the average increase of net annual precipitation (+7%). Net annual stream water and DOC loadings are primarily affected by increased dormant season precipitation. In contrast, decreased annual loading of stream nitrate (-2%) reflects a larger effect of growing season controls on stream nitrate and the effects of lengthened growing seasons in a warmer climate. Our findings suggest that leaching of nitrate and DOC from catchment soils will be affected by anthropogenic climate forcing, thereby affecting the timing and magnitude of annual stream loadings in the northeastern United States.

Characterizing the seasonal, spatial, and long-term variability of fine mineral dust (FD) is important to assess its environmental and climate impacts. FD concentrations (mineral particles with aerodynamic diameters less than 2.5 µm) were estimated using ambient, ground-based PM2.5 elemental chemistry data from over 160 remote and rural Interagency Monitoring of Protected Visual Environments (IMPROVE) sites from 2011 through 2015. FD concentrations were highest and contributed over 50% of PM2.5 mass at southwestern sites in spring and across the central and southeastern United States in summer (20-30% of PM2.5). The highest seasonal variability in FD occurred at sites in the Southeast during summer, likely associated with impacts from North African transport, which was also evidenced in the elemental ratios of calcium, iron, and aluminum. Long-term trend analyses (2000-2015) indicated widespread, regional increases in FD concentrations during spring in the West, especially in March in the Southwest. This increase was associated with an early onset of the spring dust season and correlated with the Pacific Decadal Oscillation and the El Niño Southern Oscillation. The Southeast and central United States also experienced increased FD concentrations during summer and fall, respectively. Contributions of FD to PM2.5 mass have increased in regions across the United States during all seasons, in part due to increased FD concentrations but also as a result of reductions in secondary aerosols (e.g., sulfates, nitrates, and organic carbon). Increased levels of FD have important implications for its environmental and climate impacts; mitigating these impacts will require identifying and characterizing source regions and underlying mechanisms for dust episodes.

Tobacco use is the leading cause of preventable disease and death in the United States. Increasing the unit price on tobacco products is the most effective tobacco prevention and control measure. Illicit tobacco trade (illicit trade) undermines high tobacco prices by providing tobacco users with cheaper-priced alternatives. In the United States, illicit trade primarily occurs when cigarettes are bought from states, jurisdictions, and federal reservation land with lower or no excise taxes, and sold in jurisdictions with higher taxes. Applying tax stamps to tobacco products, which provides documentation that taxes have been paid, is an important tool to combat illicit trade. Comprehensive tax stamping policy, which includes using digital, encrypted ("high-tech") stamps, applying stamps to all tobacco products, and working with tribes on stamping agreements, can further prevent and reduce illicit trade. This report describes state laws governing tax stamps on cigarettes, little cigars (cigarette-sized cigars), roll-your-own tobacco (RYOT), and tribal tobacco sales across the United States as of January 1, 2014, and assesses the extent of comprehensive tobacco tax stamping in the United States. Forty-four states (including the District of Columbia [DC]) applied traditional paper ("low-tech") tax stamps to cigarettes, whereas four authorized more effective high-tech stamps. Six states explicitly required stamps on other tobacco products (i.e., tobacco products other than cigarettes), and in approximately one third of states with tribal lands, tribes required tax stamping to address illicit purchases by nonmembers. No U.S. state had a comprehensive approach to tobacco tax stamping. Enhancing tobacco tax stamping across the country might further prevent and reduce illicit trade in the United States.

Descriptive study reporting statistics estimated based on prevalence data from 2 major population-based studies conducted in the United States between 2003 and 2011. Using US census projections, prevalence of VI and cause-specific VI in the better eye were reported by race/ethnicity, state and region, and per capita prevalence of VI by state. The study included preschool children in the United States. Analyses for this study were conducted between February 2016 and March 2017. Prevalence of VI among children aged 3 to 5 years in the United States. In 2015, more than 174 000 children aged 3 to 5 years in the United States were visually impaired. Almost 121 000 of these cases (69%) arose from simple uncorrected refractive error, and 43 000 (25%) from bilateral amblyopia. By 2060, the number of children aged 3 to 5 years with VI is projected to increase by 26%. In 2015, Hispanic white children accounted for the highest number of VI cases (66 000); this group will remain the most affected through 2060, with an increasingly large proportion of cases (37.7% in 2015 and 43.6% in 2060). The racial/ethnic group with the second most VI is projected to shift from non-Hispanic white children (26.3% in 2015 decreasing to 16.5% in 2060) to African American children (24.5% in 2015 and 22.0% in 2060). From 2015 to 2060, the states projected to have the most children with VI are California (26 600 in 2015 and 38 000 in 2060), Texas (21 500 in 2015 and 29 100 in 2060), and Florida (10 900 in 2015 and 13 900 in 2060). These data suggest that the number of preschool children with VI is projected to increase disproportionally, especially among minority populations. Vision screening for refractive error and related eye diseases may prevent a high proportion of preschool children from experiencing unnecessary VI and associated developmental delays.

Changes in the Transnational Family Structures of Mexican Farm Workers in the Era of Border Militarization.

Hamilton, Erin R; Hale, Jo Mhairi

Historically, undocumented Mexican farm workers migrated circularly, leaving family behind in Mexico on short trips to the United States. Scholars have argued that border militarization has disrupted circular migration as the costs of crossing the border lead to longer stays, increased settlement, and changing transnational family practices. Yet, no study has explored changes in the transnational family structures of Mexico-U.S. migrants that span the era of border militarization. Using data from the National Agricultural Workers Survey, we document a dramatic shift away from transnational family life (as measured by location of residence of dependent children) among undocumented Mexican farm workers and a less dramatic shift among documented Mexican farm workers in the United States between 1993 and 2012. These trends are not explained by changes in the sociodemographic characteristics of farm workers or by changing demographic conditions or rising violence in Mexico. One-half of the trend can be accounted for by lengthened duration of stay and increased connections to the United States among the undocumented, but none of the trend is explained by these measures of settlement among the documented, suggesting that some Mexican farm workers adopt new family migration strategies at first migration. Increases in border control are associated with lower likelihood that children reside in Mexico-a finding that holds up to instrumental variable techniques. Our findings confirm the argument that U.S. border militarization-a policy designed to deter undocumented migration-is instead disrupting transnational family life between Mexico and the United States and, in doing so, is creating a permanent population of undocumented migrants and their children in the United States.

Merger mania: mergers and acquisitions in the generic drug sector from 1995 to 2016.

Drug shortages and increasing generic drug prices are associated with low levels of competition. Mergers and acquisitions impact the level of competition. Record merger and acquisition activity was reported for the pharmaceutical sector in 2014/15, yet information on mergers and acquisitions in the generic drug sector are absent from the literature. This information is necessary to understand if and how such mergers and acquisitions can be a factor in drug shortages and increasing prices. Data on completed merger and acquisition deals that had a generic drug company being taken over (i.e. 'target') were extracted from Bloomberg Finance L.P. The number and announced value of deals are presented globally, for the United States, and globally excluding the United States annually from 1995 to 2016 in United States dollars. Generic drug companies comprised 9.3% of the value of all deals with pharmaceutical targets occurring from 1995 to 2016. Globally, in 1995 there were no deals, in 2014 there were 22 deals worth $1.86 billion, in 2015 there were 34 deals totalling $33.56 billion, and in 2016 there were 42 deals worth in excess of $44 billion. This substantial increase was partially attributed to Teva's 2016 acquisition of Allergan's generic drug business. The surge in mergers and acquisitions for 2015/16 was driven by deals in the United States, where they represented 89.7% of the dollar value of deals in those years. The recent blitz in mergers and acquisitions signals that the generic drug industry is undergoing a transformation, especially in the United States. This restructuring can negatively affect the level of competition that might impact prices and shortages for some products, emphasizing the importance of updating regulations and procurement policies.

China is the world's largest emitter of anthropogenic air pollutants, and measurable amounts of Chinese pollution are transported via the atmosphere to other countries, including the United States. However, a large fraction of Chinese emissions is due to manufacture of goods for foreign consumption. Here, we analyze the impacts of trade-related Chinese air pollutant emissions on the global atmospheric environment, linking an economic-emission analysis and atmospheric chemical transport modeling. We find that in 2006, 36% of anthropogenic sulfur dioxide, 27% of nitrogen oxides, 22% of carbon monoxide, and 17% of black carbon emitted in China were associated with production of goods for export. For each of these pollutants, about 21% of export-related Chinese emissions were attributed to China-to-US export. Atmospheric modeling shows that transport of the export-related Chinese pollution contributed 3-10% of annual mean surface sulfate concentrations and 0.5-1.5% of ozone over the western United States in 2006. This Chinese pollution also resulted in one extra day or more of noncompliance with the US ozone standard in 2006 over the Los Angeles area and many regions in the eastern United States. On a daily basis, the export-related Chinese pollution contributed, at a maximum, 12-24% of sulfate concentrations over the western United States. As the United States outsourced manufacturing to China, sulfate pollution in 2006 increased in the western United States but decreased in the eastern United States, reflecting the competing effect between enhanced transport of Chinese pollution and reduced US emissions. Our findings are relevant to international efforts to reduce transboundary air pollution.

Background Tick-borne illnesses represent an important class of emerging zoonoses, with climate change projected to increase the geographic range within which tick-borne zoonoses might become endemic. We evaluated the impact of latitude on the rate of change in the incidence of Lyme disease in the United States, using publicly available data. Methods We estimated state-level year-on-year incidence rate ratios (IRRs) for Lyme disease for the period 1993 to 2007 using Poisson regression methods. We evaluated between-state heterogeneity in IRRs using a random-effects meta-analytic approach. We identified state-level characteristics associated with increasing incidence using random-effects meta-regression. Results The incidence of Lyme disease in the US increased by about 80% between 1993 and 2007 (IRR per year 1.049, 95% CI [confidence interval] 1.048 to 1.050). There was marked between-state heterogeneity in the average incidence of Lyme disease, ranging from 0.008 per 100 000 person-years in Colorado to 75 per 100 000 in Connecticut, and significant between-state heterogeneity in temporal trends (p < 0.001). In multivariable meta-regression models, increasing incidence showed a linear association with state latitude and population density. These 2 factors explained 27% of the between-state variation in IRRs. No independent association was identified for other state-level characteristics. Interpretation Lyme disease incidence increased in the US as a whole during the study period, but the changes were not uniform. Marked increases were identified in northern-most states, whereas southern states experienced stable or declining rates of Lyme disease. PMID:25077101

Introduction Despite strong evidence that increasing alcohol taxes reduces alcohol-related harm, state alcohol taxes have declined in real terms during the past 3 decades. Opponents of tax increases argue that they are unfair to “responsible” drinkers and those who are financially disadvantaged. The objectives of this study were to assess the impact of hypothetical state alcohol tax increases on the cost of alcohol for adults in the United States on the basis of alcohol consumption and sociodemographic characteristics. Methods The increased net cost of alcohol (ie, product plus tax) from a series of hypothetical state alcohol tax increases was modeled for all 50 states using data from the 2011 Behavioral Risk Factor Surveillance System, IMPACT Databank, and the Alcohol Policy Information System. Costs were assessed by drinking pattern (excessive vs nonexcessive) and by sociodemographic characteristics. Results Among states, excessive drinkers would pay 4.8 to 6.8 times as much as nonexcessive drinkers on a per capita basis and would pay at least 72% of aggregate costs. For nonexcessive drinkers, the annual cost from even the largest hypothetical tax increase ($0.25 per drink) would average less than $10.00. Drinkers with higher household incomes and non-Hispanic white drinkers would pay higher per capita costs than people with lower incomes and racial/ethnic minorities. Conclusion State-specific tax increases would cost more for excessive drinkers, those with higher incomes, and non-Hispanic whites. Costs to nonexcessive drinkers would be modest. Findings are relevant to developing evidence-based public health practice for a leading preventable cause of death. PMID:27197080

Background Increasing tobacco taxes to increase price is a proven tobacco control measure. This paper investigates how smokers respond to tax and price increases in their choice of discount brand cigarettes vs. premium brands. Objective To estimate how increase in the tax rate can affect smokers’ choice of discount brands versus premium brands. Methods Using data from ITC Surveys in Canada and the United States, a logit model was constructed to estimate the probability of choosing discount brand cigarettes in response to its price changes relative to premium brands, controlling for individual-specific demographic and socio-economic characteristics and regional effects. The self-reported price of an individual smoker is used in a random-effects regression model to impute price and to construct the price ratio for discount and premium brands for each smoker, which is used in the logit model. Findings An increase in the ratio of price of discount brand cigarettes to the price of premium brands by 0.1 is associated with a decrease in the probability of choosing discount brands by 0.08 in Canada. No significant effect is observed in case of the United States. Conclusion The results of the model explain two phenomena: (1) the widened price differential between premium and discount brand cigarettes contributed to the increased share of discount brand cigarettes in Canada in contrast to a relatively steady share in the United States during 2002–2005, and (2) increasing the price ratio of discount brands to premium brands—which occurs with an increase in specific excise tax—may lead to upward shifting from discount to premium brands rather than to downward shifting. These results underscore the significance of studying the effectiveness of tax increases in reducing overall tobacco consumption, particularly for specific excise taxes. PMID:23986408

Cardiovascular disease (CVD) is the leading cause of death in the United States, but regional variation within the United States is large. Comparable and consistent state-level measures of total CVD burden and risk factors have not been produced previously. To quantify and describe levels and trends of lost health due to CVD within the United States from 1990 to 2016 as well as risk factors driving these changes. Using the Global Burden of Disease methodology, cardiovascular disease mortality, nonfatal health outcomes, and associated risk factors were analyzed by age group, sex, and year from 1990 to 2016 for all residents in the United States using standardized approaches for data processing and statistical modeling. Burden of disease was estimated for 10 groupings of CVD, and comparative risk analysis was performed. Data were analyzed from August 2016 to July 2017. Residing in the United States. Cardiovascular disease disability-adjusted life-years (DALYs). Between 1990 and 2016, age-standardized CVD DALYs for all states decreased. Several states had large rises in their relative rank ordering for total CVD DALYs among states, including Arkansas, Oklahoma, Alabama, Kentucky, Missouri, Indiana, Kansas, Alaska, and Iowa. The rate of decline varied widely across states, and CVD burden increased for a small number of states in the most recent years. Cardiovascular disease DALYs remained twice as large among men compared with women. Ischemic heart disease was the leading cause of CVD DALYs in all states, but the second most common varied by state. Trends were driven by 12 groups of risk factors, with the largest attributable CVD burden due to dietary risk exposures followed by high systolic blood pressure, high body mass index, high total cholesterol level, high fasting plasma glucose level, tobacco smoking, and low levels of physical activity. Increases in risk-deleted CVD DALY rates between 2006 and 2016 in 16 states suggest additional unmeasured risks beyond these traditional factors. Large disparities in total burden of CVD persist between US states despite marked improvements in CVD burden. Differences in CVD burden are largely attributable to modifiable risk exposures.

The decrease in overall death rates in the United States may mask changes in death rates from specific conditions. To examine temporal trends in the age-standardized death rates and in the number of deaths from the 6 leading causes of death in the United States. Analyses of vital statistics data on mortality in the United States from 1970 to 2002. The age-standardized death rate and number of deaths (coded as underlying cause) from each of the 6 leading causes of death: heart disease, stroke, cancer, chronic obstructive pulmonary disease, accidents (ie, related to transportation [motor vehicle, other land vehicles, and water, air, and space] and not related to transportation [falls, fire, and accidental posioning]), and diabetes mellitus. The age-standardized death rate (per 100,000 per year) from all causes combined decreased from 1242 in 1970 to 845 in 2002. The largest percentage decreases were in death rates from stroke (63%), heart disease (52%), and accidents (41%). The largest absolute decreases in death rates were from heart disease (262 deaths per 100,000), stroke (96 deaths per 100,000), and accidents (26 deaths per 100,000).The death rate from all types of cancer combined increased between 1970 and 1990 and then decreased through 2002, yielding a net decline of 2.7%. In contrast, death rates doubled from chronic obstructive pulmonary disease over the entire time interval and increased by 45% for diabetes since 1987. Despite decreases in age-standardized death rates from 4 of the 6 leading causes of death, the absolute number of deaths from these conditions continues to increase, although these deaths occur at older ages. The absolute number of deaths and age at death continue to increase in the United States. These temporal trends have major implications for health care and health care costs in an aging population.

Attribution of Trends and Variability in Surface Ozone over the United States

NASA Technical Reports Server (NTRS)

Strode, Sarah; Cooper, Owen; Damo, Megan; Logan, Jennifer; Rodriquez, Jose; Strahan, Susan; Witte, Jacquie

2013-01-01

Concentrations of tropospheric ozone, a greenhouse gas and air pollutant, are impacted by changes in precursor emissions as well meteorology and influx from the stratosphere. Observations show a decreasing trend in summertime surface ozone at rural stations in the eastern United States, while some western stations show increasing trends, particularly in springtime. We use the Global Modeling Initiative (GMI) global chemical transport model to investigate the roles of precursor emission changes, meteorological variability, and stratosphere-troposphere exchange (STE) in explaining observed trends in surface ozone from rural sites in the United States from 1991-2010. The model's interannual variability shows significant correlations with observations from many of the surface sites. We also compare the simulated ozone to ozonesonde data for several locations with sufficiently long records. We compare a simulation with time-dependent precursor emissions, including emission reductions over the United States and Europe and increases over Asia, to a simulation with fixed emissions to quantify the impact of changing emissions on the surface trends. The simulation with varying emissions reproduces much of the east-west difference in summertime ozone over the U.S., although it generally underestimates the negative trend in the East. In contrast, the fixed-emission simulation shows increasing ozone at both eastern and western sites. We will discuss possible causes of this behavior, including long-range transport and STE.

Managing the Diabetic Foot Ulcer: How Best Practices Fit the Real 2018 United States.

PubMed

Ilonzo, Nicole; Patel, Munir; Lantis, John C

2018-06-01

Diabetes Mellitus is a serious systemic illness that has an epidemic-like increasing prevalence in the United States, as well as the rest of the world. With the increasing number of people with diabetes comes the higher incidence of diabetes-related complications. One of these known complications, diabetic foot ulcers (DFU), has an estimated lifetime incidence of 15% in diabetics. Having a DFU increases the risk of infection, amputation, and even death, which is why prompt treatment and surveillance of such ulcers is imperative. Multiple organizations and journals have recently published best practices to heal and close DFU. Despite these guidelines, it is estimated that only 50% of all diabetic foot ulcers close within one year in the United States. To further confuse this picture, many trials include postoperative wounds that behave in a very different way than chronic wounds. The management of diabetic ulcers requires an understanding of not only the pathophysiology along with a multi-modal approach involving local wound care, pressure prevention, infection control, and, in some, revascularization, but also how care is delivered in the United States presently. In this review, we hope to elucidate the current knowledge and modalities used in ulcer management and to focus on key areas and best practices to inform the clinician, both in what they should do and what they can do.

Vulnerability of US and European electricity supply to climate change

NASA Astrophysics Data System (ADS)

van Vliet, Michelle T. H.; Yearsley, John R.; Ludwig, Fulco; Vögele, Stefan; Lettenmaier, Dennis P.; Kabat, Pavel

2012-09-01

In the United States and Europe, at present 91% and 78% (ref. ) of the total electricity is produced by thermoelectric (nuclear and fossil-fuelled) power plants, which directly depend on the availability and temperature of water resources for cooling. During recent warm, dry summers several thermoelectric power plants in Europe and the southeastern United States were forced to reduce production owing to cooling-water scarcity. Here we show that thermoelectric power in Europe and the United States is vulnerable to climate change owing to the combined impacts of lower summer river flows and higher river water temperatures. Using a physically based hydrological and water temperature modelling framework in combination with an electricity production model, we show a summer average decrease in capacity of power plants of 6.3-19% in Europe and 4.4-16% in the United States depending on cooling system type and climate scenario for 2031-2060. In addition, probabilities of extreme (>90%) reductions in thermoelectric power production will on average increase by a factor of three. Considering the increase in future electricity demand, there is a strong need for improved climate adaptation strategies in the thermoelectric power sector to assure futureenergy security.

Regional and seasonal response of a West Nile virus vector to climate change.

PubMed

Morin, Cory W; Comrie, Andrew C

2013-09-24

Climate change will affect the abundance and seasonality of West Nile virus (WNV) vectors, altering the risk of virus transmission to humans. Using downscaled general circulation model output, we calculate a WNV vector's response to climate change across the southern United States using process-based modeling. In the eastern United States, Culex quinquefasciatus response to projected climate change displays a latitudinal and elevational gradient. Projected summer population depressions as a result of increased immature mortality and habitat drying are most severe in the south and almost absent further north; extended spring and fall survival is ubiquitous. Much of California also exhibits a bimodal pattern. Projected onset of mosquito season is delayed in the southwestern United States because of extremely dry and hot spring and summers; however, increased temperature and late summer and fall rains extend the mosquito season. These results are unique in being a broad-scale calculation of the projected impacts of climate change on a WNV vector. The results show that, despite projected widespread future warming, the future seasonal response of C. quinquefasciatus populations across the southern United States will not be homogeneous, and will depend on specific combinations of local and regional conditions.

Cross-national comparisons of gender differences in late-life depressive symptoms in Japan and the United States.

2013-05-01

This study compared changes in self-reported depressive symptoms in the United States and Japan across 2 points in time. The investigation focused on the gendered processes of intergenerational coresidence and support as the primary distinctions between nations. Fixed-effects models were fit to examine the covariates of depressive symptoms in the Health and Retirement Study (HRS) and the Nihon University Japanese Longitudinal Study of Aging. Gender differences in depressive symptoms persisted across survey waves in both nations, with Japanese men reporting sharper increases by Time 2 than Japanese women. Getting older was associated with more depressive symptoms among Japanese men, whereas income provided a slight buffering effect. Coresiding with daughters also appeared to protect Japanese men and women with functional limitations from depressive symptoms. HRS data demonstrated that changes in marital status and physical health were correlated with increased depressive symptoms for men and women in the United States. The analyses revealed more variety in Center for Epidemiologic Studies Depression scale reports by gender in Japan than in the United States. Future research should consider the diversity of contemporary Japanese households, reflecting new interpretations of traditional family support relationships.

2017-07-13

Understanding historical changes in flood damage and the underlying mechanisms is critical for predicting future changes for better adaptations. In this study, a detailed assessment of flood damage for 1950–1999 is conducted at the state level in the conterminous United States (CONUS).

Understanding historical changes in flood damage and the underlying mechanisms is critical for predicting future changes for better adaptations. In this study, a detailed assessment of flood damage for 1950–1999 is conducted at the state level in the conterminous United States (CONUS). Geospatial datasets on possible influencing factors are then developed by synthesizing natural hazards, population, wealth, cropland and urban area to explore the relations with flood damage. A considerable increase in flood damage in CONUS is recorded for the study period which is well correlated with hazards.

Cultural diversity is increasing in the United States as increasing numbers of minorities enter the United States from abroad, and cultural diversity is especially prevalent in the health care workplace. In fact, the health care professions are particularly interested in the presence of minorities among caregivers because this often enhances the cultural competence of care delivery. Nevertheless, subtle discrimination can still be found, and managers must be alert that such behavior is not tolerated. Use of the Giger-Davidhizar Cultural Assessment Model can provide managers with information needed to respond to diversity among staff appropriately.

Initiatives to increase the number, persistence, and success of women in physics in the United States reach preteen girls through senior women. Programs exist at both the local and national levels. In addition, researchers have investigated issues related to gender equity in physics and physics education. Anecdotal evidence suggests increased media coverage of the underrepresentation of women in science. All of these efforts are motivated and made more effective by the continued collection and presentation of data on the presence, persistence, and promise of women in physics.

A survey of dermatophytes isolated from patients seeking medical advice was made from 1979 to 1981 in the United States. The survey included 54 locations with data from 40 cities and 2 states. Correlations of these data with that of the other localities of the world were made to illustrate the dynamic epidemiology of several common dermatophytes. The most often isolated dermatophyte in this survey was Trichophyton rubrum having 53.66% of the total for these three calendar years. In a chronological listing of ringworm infections caused by this organism, many areas of the world have reported similar increased incidence of this pathogen. Trichophyton tonsurans was isolated 27.85% of the total. A dramatic increase of this pathogen as a cause of tinea capitis has been observed in most cities of the United States. It has been isolated in 25 different countries of the world. The percentage of isolation of Trichophyton mentagrophytes was 8.56%. This percentage may not be near the true incidence of infection by this dermatophyte because the infections are mild and respond to treatment without the individual seeking medical advice. Since the 1950s the percentage of isolations of the total has dropped for T. mentagrophytes in the United States. Epidermophyton floccosum accounted for 4.36% of the total. In a few areas of the world it causes over 30% of the total of dermatophytoses. Microsporum canis was isolated 3.72% of the total in the United States. It has recently been reported to be the dominant agent of tinea capitis in several South American countries, Tucson, Arizona and Kuwait. Once the dominant pathogen of tinea capitis in children in the United States, it was replaced by Microsporum audouinii before 1960. Today in the United States, M. audouinii only accounts for 0.30% of the total. It is considered eliminated as a pathogen in England. In this survey, isolated less than 1.0% of the total were Microsporum gypseum. Microsporum ferrugineum , Microsporum nanum , Microsporum fulvum and Trichophyton schoenleinii . Trichophyton meginii and Trichophyton terrestre were reported isolated but no numerical data were available.

Mobility and volatility: What is behind the rising income inequality in the United States

NASA Astrophysics Data System (ADS)

Wu, Huixuan; Li, Yao

2018-02-01

Inequality of family incomes in the United States has increased significantly in the past four decades. This is largely interpreted as a result of unequal mobility, e.g., the rich can get richer at a faster pace than the rest of the population. However, using nationally representative data and the Fokker-Planck equation, our study shows that income mobility in the United States has remained stable. Instead, we find another factor - income volatility, which measures the instability of incomes - has increased considerably and caused the surge of income inequality. In addition, the rising volatility is associated with the plummeting of income-growth opportunity, creating the feeling that the American Dream is in decline. Volatility has often been overlooked in previous studies on inequality, partially because mobility and volatility are usually studied separately. By contrast, the Fokker-Planck equation takes both mobility and volatility into consideration, making it a more comprehensive model.

Drug-resistant Neisseria gonorrhoeae: latest developments.

Gonorrhea is the second most frequently reported notifiable disease in the United States and is becoming increasingly common in Europe. The purpose of this review was to assess the current state of drug-resistant Neisseria gonorrhoeae in order to evaluate future prospects for its treatment. An exhaustive literature search was conducted to include the latest research regarding drug resistance and treatment guidelines for gonorrhea. Gonococci have acquired all known resistance mechanisms to all antimicrobials used for treatment. Currently, the European Union, the United States, and the United Kingdom have established surveillance programs to assess, on a yearly basis, the development of gonococcal resistance. Current treatment guidelines are being threatened by the increasing number of ceftriaxone-, cefixime-, and azithromycin-resistant N. gonorrhoeae strains being detected worldwide. This has led the scientific community to develop new treatment options with new molecules in order to persevere in the battle against this "superbug".

Despite major demographic changes over the past 50 years and strong evidence that time spent with a spouse is important for marriages, we know very little about how time with a spouse has changed—or not—in the United States. Using time diary data from 1965–2012, we examine trends in couples’ shared time in the United States during a period of major changes in American marriages and families. We find that couples without children spent more total time together and time alone together n 2012 than they did in 1965, with total time and time alone together both peaking in 1975. For parents, time spent together increased between 1965 and 2012, most dramatically for time spent with a spouse and children. Decomposition analyses show that changes in behavior rather than changing demographics explain these trends, and we find that the increases in couples’ shared time are primarily concentrated in leisure activities.

The Cost of Distribution System Upgrades to Accommodate Increasing Penetrations of Distributed Photovoltaic Systems on Real Feeders in the United States

DOE Office of Scientific and Technical Information (OSTI.GOV)

Horowitz, Kelsey A; Ding, Fei; Mather, Barry A

The increasing deployment of distributed photovoltaic systems (DPV) can impact operations at the distribution level and the transmission level of the electric grid. It is important to develop and implement forward-looking approaches for calculating distribution upgrade costs that can be used to inform system planning, market and tariff design, cost allocation, and other policymaking as penetration levels of DPV increase. Using a bottom-up approach that involves iterative hosting capacity analysis, this report calculates distribution upgrade costs as a function of DPV penetration on three real feeders - two in California and one in the Northeastern United States.

Hispanic Americans living in the United States and their risk for obesity, diabetes and kidney disease: Genetic and environmental considerations.

The Hispanic American, the largest minority population in the United States, is at increased risk for obesity, diabetes and end-stage renal disease. Here we review genetic and environmental factors that might account for their increased risk for these conditions. Whereas many environmental and genetic factors have important roles in driving the increased risk for obesity and kidney disease in this population, a case is made that excessive intake of sugary beverages is a contributory cause. Studies focusing on decreasing intake of sugary beverages among the Hispanic American could potentially reduce renal and cardiovascular complications in this population.

Climate change, humidity, and mortality in the United States

2014-01-01

This paper estimates the effects of humidity and temperature on mortality rates in the United States (c. 1973–2002) in order to provide an insight into the potential health impacts of climate change. I find that humidity, like temperature, is an important determinant of mortality. Coupled with Hadley CM3 climate-change predictions, I project that mortality rates are likely to change little on the aggregate for the United States. However, distributional impacts matter: mortality rates are likely to decline in cold and dry areas, but increase in hot and humid areas. Further, accounting for humidity has important implications for evaluating these distributional effects. PMID:25328254

To explore preimmigration experiences of violence and postimmigration health status in male-to-female transgender individuals (n = 45) from Mexico applying for asylum in the United States. We used a document review process to examine asylum declarations and psychological evaluations of transgender Mexican asylum seekers in the United States from 2012. We coded documents in 2013 and 2014 using NVivo, a multidisciplinary team reviewed them, and then we analyzed them for themes. Mexican transgender asylum applicants experienced pervasive verbal, physical, and sexual abuse from multiple sources, including family, school, community, and police. Applicants also experienced discrimination in school and in the workplace. Applicants immigrated to the United States to escape persistent assaults and threats to their life. Applicants suffered health and psychological effects from their experiences in Mexico that affected opportunities in the United States for employment, education, and social inclusion. Additional social protections for transgender individuals and antidiscrimination measures in Mexican schools and workplaces are warranted as are increased mental health assessment and treatment, job training, and education services for asylum seekers in the United States.

The Demography of Canada and the United States from the 1980s to the 2000s A Summary of Changes and a Statistical Assessment

Barbieri, Magali; Ouellette, Nadine

2013-01-01

Canada and the United States have enjoyed vigorous population growth since the early 1980s. Although mortality is slightly higher in the United States than in Canada, this is largely offset by much higher fertility, with a total fertility rate at replacement level, compared with just 1.5 children per woman in Canada. The United States is also the world’s largest immigrant receiving country, although its immigration rate is only half that of Canada, where today one person in five is foreign-born, versus one in eight in the United States. Based on recent trends in fertility, mortality and international migration, the populations of these two North American countries will continue to grow over the next five decades, but at a progressively slower pace. The most acute demographic issue today is not, as in Europe, that of imminent population decline, but rather of the geographic and social inequalities which have increased steadily since the early 1980s and which are reflected in major fertility and health differentials between regions and social groups.

Movement between Mexico and Canada: Analysis of a New Migration Stream

Massey, Douglas; Brown, Amelia E.

2011-01-01

In this analysis we use data from the Mexican Migration Project to contrast processes of Mexican migration to Canada and the United States. All migrants to Canada entered through the Seasonal Agricultural Worker Program and consistent with program criteria, migration there is strongly predicted by marital status and number of dependents, yielding a migrant population that is made up of males of prime labor-force age who are married and have multiple children at home. In contrast, the vast majority of migrants to the United States are undocumented and thus self-selected without regard to marital status or parenthood. Migration to the United States is strongly predicted by age, and migration probabilities display the age curve classically associated with labor migration. Within countries of destination, migrants to Canada enjoy superior labor market outcomes compared with those to the United States, with higher wages and more compact work schedules that yield higher earnings and shorter periods away from families compared with undocumented migrants to the United States. Labor migration to Canada also tends to operate as a circular flow with considerable repeat migration whereas undocumented migrants to the United States do not come and go so regularly, as crossing the Mexico-U.S. border has become increasingly difficult and costly.

Increasing levels of obesity could compromise future gains in life expectancy in low- and high-income countries. Although excess mortality associated with obesity and, more generally, higher levels of body mass index (BAI) have been investigated in the United States, there is little research about the impact of obesity on mortality in Latin American countries, where very the rapid rate of growth of prevalence of obesity and overweight occur jointly with poor socioeconomic conditions. The aim of this article is to assess the magnitude of excess mortality due to obesity and overweight in Mexico and the United States. For this purpose, we take advantage of two comparable data sets: the Health and Retirement Study 2000 and 2004 for the United States, and the Mexican Health and Aging Study 2001 and 2003 for Mexico. We find higher excess mortality risks among obese and overweight individuals aged 60 and older in Mexico than in the United States. Yet, when analyzing excess mortality among different socioeconomic strata, we observe greater gaps by education in the United States than in Mexico. We also find that although the probability of experiencing obesity-related chronic diseases among individuals with high BMI is larger for the U.S. elderly, the relative risk of dying conditional on experiencing these diseases is higher in Mexico.

Physician supply and medical education in California. A comparison with national trends.

Concerns have been voiced about an impending oversupply of physicians in the United States. Do these concerns also apply to California, a state with many unique demographic characteristics? We examined trends in physician supply and medical education in California and the United States between 1980 and 1995 to better inform the formulation of workforce policies appropriate to the state's requirements for physicians. We found that similar to the United States, California has more than an ample supply of physicians in the aggregate, but too many specialists, too few underrepresented racial/ethnic minority physicians, and poor distribution of physicians across the state. However, recent growth in the supply of practicing physicians and resident physicians per capita in California has been much less dramatic than in the country overall. The state's unusually high rate of population growth has enabled California, unlike the United States as a whole, to absorb large increases in the number of practicing physicians and residents during 1980 to 1995 without substantially increasing the physician-to-population ratio. Due to a projected slowing of the state's rate of population growth, the supply of physicians per capita in the state will begin to rise steeply in coming years unless the state implements prompt reductions in the production of specialists. An immediate 25% reduction in specialist residency positions would be necessary to bring the state's supply of practicing specialists in line with projected physician requirements for the state by 2020. We conclude that major changes will be required if the state's residency programs and medical schools are to produce the number and mix of physicians the state requires. California's medical schools and residency programs will need to act in concert with federal and state government to develop effective policies to address the imbalance between physician supply and state requirements.

Recycled Cell Phones - A Treasure Trove of Valuable Metals

USGS Publications Warehouse

Sullivan, Daniel E.

2006-01-01

This U.S. Geological Survey (USGS) Fact Sheet examines the potential value of recycling the metals found in obsolete cell phones. Cell phones seem ubiquitous in the United States and commonplace throughout most of the world. There were approximately 1 billion cell phones in use worldwide in 2002. In the United States, the number of cell phone subscribers increased from 340,000 in 1985 to 180 million in 2004. Worldwide, cell phone sales have increased from slightly more than 100 million units per year in 1997 to an estimated 779 million units per year in 2005. Cell phone sales are projected to exceed 1 billion units per year in 2009, with an estimated 2.6 billion cell phones in use by the end of that year. The U.S. Environmental Protection Agency estimated that, by 2005, as many as 130 million cell phones would be retired annually in the United States. The nonprofit organization INFORM, Inc., anticipated that, by 2005, a total of 500 million obsolete cell phones would have accumulated in consumers' desk drawers, store rooms, or other storage, awaiting disposal. Typically, cell phones are used for only 1 1/2 years before being replaced. Less than 1 percent of the millions of cell phones retired and discarded annually are recycled. When large numbers of cell phones become obsolete, large quantities of valuable metals end up either in storage or in landfills. The amount of metals potentially recoverable would make a significant addition to total metals recovered from recycling in the United States and would supplement virgin metals derived from mining.

Characterization of increased persistence and intensity of precipitation in the northeastern United States

2015-03-01

We present evidence of increasing persistence in daily precipitation in the northeastern United States that suggests that global circulation changes are affecting regional precipitation patterns. Meteorological data from 222 stations in 10 northeastern states are analyzed using Markov chain parameter estimates to demonstrate that a significant mode of precipitation variability is the persistence of precipitation events. We find that the largest region-wide trend in wet persistence (i.e., the probability of precipitation in 1 day and given precipitation in the preceding day) occurs in June (+0.9% probability per decade over all stations). We also find that the study region is experiencing an increase in the magnitude of high-intensity precipitation events. The largest increases in the 95th percentile of daily precipitation occurred in April with a trend of +0.7 mm/d/decade. We discuss the implications of the observed precipitation signals for watershed hydrology and flood risk.

Factors Underlying the Temporal Increase in Maternal Mortality in the United States

OBJECTIVE To identify the factors underlying the recent increase in maternal mortality ratios (maternal deaths per 100,000 live births) in the United States. METHODS We carried out a retrospective study with data on maternal deaths and live births in the United States from 1993 to 2014 obtained from the birth and death files of the Centers for Disease Control and Prevention. Underlying causes of death were examined between 1999 and 2014 using International Classification of Diseases, Tenth Revision (ICD-10) codes. Poisson regression was used to estimate maternal mortality rate ratios (RR) and 95% confidence intervals (CI) after adjusting for the introduction of a separate pregnancy question and the standard pregnancy checkbox on death certificates, and adoption of ICD-10. RESULTS Maternal mortality ratios increased from 7.55 in 1993, to 9.88 in 1999 and to 21.5 per 100,000 live births in 2014 (RR 2014 vs 1993 2.84, 95% CI 2.49 to 3.24; RR 2014 vs 1999 2.17, 95% CI 1.93 to 2.45). The increase in maternal deaths from 1999 to 2014 was mainly due to increases in maternal deaths associated with two new ICD-10 codes (O26.8 i.e., primarily renal disease and O99 i.e., other maternal diseases classifiable elsewhere); exclusion of such deaths abolished the increase in mortality (RR 1.09, 95% CI 0.94 to 1.27). Regression adjustment for improvements in surveillance also abolished the temporal increase in maternal mortality ratios (adjusted maternal mortality ratios 7.55 in 1993, 8.00 per 100,000 live births in 2013; adjusted RR 2013 vs 1993 1.06, 95% CI 0.90 to 1.25). CONCLUSION Recent increases in maternal mortality ratios in the United States are likely an artifact of improvements in surveillance and highlight past underestimation of maternal death. Complete ascertainment of maternal death in populations remains a challenge even in countries with good systems for civil registration and vital statistics. PMID:27926651

The topic of modern-day slavery or human trafficking has received increased media and national attention. However, to date there has been limited research on the nature and scope of human trafficking in the United States. This article describes and synthesizes nine reports that assess the U.S. service organizations' legal representative knowledge of, and experience with, human trafficking cases, as well as information from actual cases and media reports. This article has five main goals: (a) to define what human trafficking is, and is not; (b) to describe factors identified as contributing to vulnerability to being trafficked and keeping a person entrapped in the situation; (c) to examine how the crime of human trafficking differs from other kinds of crimes in the United States; (d) to explore how human trafficking victims are identified; and, (e) to provide recommendations to better address human trafficking in the United States.

Underground Injection Control, Hydraulic Fracturing, and Sources of Drinking Water in the Western United States

Jackson, R. B.; Kang, M.

2016-12-01

Oil and gas extraction is expanding in the United States, attributable to the success of high-volume hydraulic fracturing, and associated wastewater disposal is increasing as a result. The United States currently has approximately 180,000 Class II injection wells associated with the oil and gas industry, more than 50,000 of them in California. Hydraulic fracturing and underground injection often occur many thousands of feet belowground. Previously, however, we documented shallow hydraulic fracturing and other oil and gas activities across the western United States in particular, including California and Wyoming. In eight CA counties, for example, as many as 19% and 35% of oil/gas activities have occurred directly in freshwater zones and USDWs, respectively (Kang and Jackson 2016 PNAS). Here we expand this analysis to examine the underground injection control program and accompanying hydrogeologic variables found in California and elsewhere.

Natural production of the radionuclide chlorine-36 (36Cl) has provided a valuable tracer for groundwater studies. The nuclear industry, especially the testing of thermonuclear weapons, has also produced large amounts of 36Cl that can be detected in many samples of groundwater. In order to be most useful in hydrologic studies, the natural production prior to 1952 should be distinguished from more recent artificial sources. The object of this study was to reconstruct the probable preanthropogenic levels of 36Cl in groundwater in the United States. Although significant local variations exist, they are superimposed on a broad regional pattern of 36Cl/Cl ratios in the United States. Owing to the influence of atmospherically transported ocean salt, natural ratios of 36Cl/total Cl are lowest near the coast and increase to a maximum in the central Rocky Mountains of the United States.

Biosimilars have become a subject of great interest in the past few years. The European Union and the United States are seeing an increasing number of biosimilar applications and approvals. The development of a biosimilar is significantly more complex and costly than a small molecule generic product. In the European Union, there has been a wider use of these medications compared to the United States. More biosimilars are gaining approval in the United States, and these products will likely alter the healthcare system in highly impactful ways. Understanding the regulatory process, the risks, and benefits will enable clinicians to be prepared and maximize the utility of these medications when they enter the market. This article introduces the concept of a biosimilar, discusses the regulatory process in the United States, and reviews the risks and benefits of these products. Copyright © 2017 Elsevier Inc.

2013-01-01

A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long-term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analyses. Depletion is directly calculated using calibrated groundwater models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900–2008 totals approximately 1,000 cubic kilometers (km3). Furthermore, the rate of groundwater depletion has increased markedly since about 1950, with maximum rates occurring during the most recent period (2000–2008) when the depletion rate averaged almost 25 km3 per year (compared to 9.2 km3 per year averaged over the 1900–2008 timeframe).

Potential Impacts of Climate Change on Stream Water Temperatures Across the United States

NASA Astrophysics Data System (ADS)

Ehsani, N.; Knouft, J.; Ficklin, D. L.

2017-12-01

Analyses of long-term observation data have revealed significant changes in several components of climate and the hydrological cycle over the contiguous United States during the twentieth and early twenty-first century. Mean surface air temperatures have significantly increased in most areas of the country. In addition, water temperatures are increasing in many watersheds across the United States. While there are numerous studies assessing the impact of climate change on air temperatures at regional and global scales, fewer studies have investigated the impacts of climate change on stream water temperatures. Projecting increases in water temperature are particularly important to the conservation of freshwater ecosystems. To achieve better insights into attributes regulating population and community dynamics of aquatic biota at large spatial and temporal scales, we need to establish relationships between environmental heterogeneity and critical biological processes of stream ecosystems at these scales. Increases in stream temperatures caused by the doubling of atmospheric carbon dioxide may result in a significant loss of fish habitat in the United States. Utilization of physically based hydrological-water temperature models is computationally demanding and can be onerous to many researchers who specialize in other disciplines. Using statistical techniques to analyze observational data from 1760 USGS stream temperature gages, our goal is to develop a simple yet accurate method to quantify the impacts of climate warming on stream water temperatures in a way that is practical for aquatic biologists, water and environmental management purposes, and conservation practitioners and policy-makers. Using an ensemble of five global climate models (GCMs), we estimate the potential impacts of climate change on stream temperatures within the contiguous United States based on recent trends. Stream temperatures are projected to increase across the US, but the magnitude of the changes are not expected to be uniform across the region and these relationships are expected to vary from month to month. Combined with expected changes in stream flows, the projected changes in the thermal regimes of streams can fundamentally transform stream habitats and the distribution of biodiversity.

Comparison of the U.S. lead recycling industry in 1998 and 2011

Wilburn, David R.

2014-01-01

Since 1998, the structure of the lead recycling industry has changed and trade patterns of the domestic lead recycling industry have shifted. Although the domestic demand for lead has remained relatively constant since 1998, production of lead has increasingly shifted to the domestic secondary lead industry. The last primary lead smelter in the United States closed at the end of 2013, at which time the secondary lead industry became the sole source of domestic lead production. The amount of lead recovered annually from scrap batteries generally increased from about 900,000 metric tons in 1995 to more than 1,100,000 metric tons in 2012. The percentage of total U.S. lead production attributed to battery scrap increased from 65 percent in 1995 to 87 percent in 2012. Since the North American Free Trade Agreement took effect in 1994, trade patterns among the United States, Canada, and Mexico have changed for recycled lead products. In the late 1990s, the principal sources of lead waste and scrap not derived from batteries were Canada, Mexico, and South America; by 2011, the principal sources were Central America and Asia, with decreasing amounts from Canada and South America. Since 1998, the amount of lead derived from imported batteries and scrap from Canada has ranged from 50 to 90 percent, and the amount imported from Mexico has ranged from 3 to 20 percent. Canada received about 50 percent of the lead contained in spent lead-acid batteries and scrap exported from the United States in 1998, and Mexico received about 4 percent. By 2012, however, the amount of lead scrap exported to Canada had decreased to about 10 percent, and the amount of lead-based scrap products, primarily batteries, exported to Mexico from the United States had increased to 47 percent. Vertical integration of the domestic secondary lead industry and higher costs required to implement more stringent ambient air standards in the United States have led some companies to shift lead recycling operations to Mexico. U.S. secondary lead producers are increasingly competing with Canadian and Mexican facilities for market share.

Background The effects of weather on West Nile virus (WNV) mosquito populations in the United States have been widely reported, but few studies assess their overall impact on transmission to humans. Objectives We investigated meteorologic conditions associated with reported human WNV cases in the United States. Methods We conducted a case–crossover study to assess 16,298 human WNV cases reported to the Centers for Disease Control and Prevention from 2001 to 2005. The primary outcome measures were the incidence rate ratio of disease occurrence associated with mean weekly maximum temperature, cumulative weekly temperature, mean weekly dew point temperature, cumulative weekly precipitation, and the presence of ≥ 1 day of heavy rainfall (≥ 50 mm) during the month prior to symptom onset. Results Increasing weekly maximum temperature and weekly cumulative temperature were similarly and significantly associated with a 35–83% higher incidence of reported WNV infection over the next month. An increase in mean weekly dew point temperature was significantly associated with a 9–38% higher incidence over the subsequent 3 weeks. The presence of at least 1 day of heavy rainfall within a week was associated with a 29–66% higher incidence during the same week and over the subsequent 2 weeks. A 20-mm increase in cumulative weekly precipitation was significantly associated with a 4–8% increase in incidence of reported WNV infection over the subsequent 2 weeks. Conclusions Warmer temperatures, elevated humidity, and heavy precipitation increased the rate of human WNV infection in the United States independent of season and each others’ effects.

2015-09-01

To investigate whether changes in death certificate coding and reporting practices explain part or all of the recent increase in the rate of fatal falls in adults aged 65 and older in the United States. Trends in coding and reporting practices of fatal falls were evaluated under mortality coding schemes for International Classification of Diseases (ICD), Ninth Revision (1992-1998) and Tenth Revision (1999-2005). United States, 1992 to 2005. Individuals aged 65 and older with falls listed as the underlying cause of death (UCD) on their death certificates. The primary outcome was annual fatal falls rates per 100,000 U.S. residents aged 65 and older. Coding practice was assessed through analysis of trends in rates of specific UCD fall ICD e-codes over time. Reporting quality was assessed by examining changes in the location on the death certificate where fall e-codes were reported, in particular, the percentage of fall e-codes recorded in the proper location on the death certificate. Fatal falls rates increased over both time periods: 1992 to 1998 and 1999 to 2005. A single falls e-code was responsible for the increasing trend of fatal falls overall from 1992 to 1998 (E888, other and unspecified fall) and from 1999 to 2005 (W18, other falls on the same level), whereas trends for other falls e-codes remained stable. Reporting quality improved steadily throughout the study period. Better reporting quality, not coding practices, contributed to the increasing rate of fatal falls in older adults in the United States from 1992 to 2005. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

2012-01-01

Context Interest in the role of fibrates has intensified with the publication of the negative ACCORD trial with fenofibrate, especially since the evidence for clinical outcomes benefit for fibrates is heavily weighted on older fibrates, gemfibrozil and clofibrate. Objective This study seeks to examine trends in the current use of fibrates, and for fenofibrate, to illuminate the relationship between differences in the availability of proprietary versus generic formulations and use and economic implications in the United States (US) compared with Canada. Design/Setting/Patients Population-level, cohort study using IMS Health data in the United States and Canada of patients prescribed fibrates between 2002 and 2009. Main Outcome Measure(s) Fibrate prescribing and expenditures. Results From 2002–2009, fibrate prescriptions increased 117.1% in the US, by 12,000/month to 2.1 million prescriptions/month, yet only increased by 18.1% in Canada. (p<0.001) Fenofibrate use was relatively constant in Canada, while in the US, it increased by 159.3%, comprising 47.9% of total fibrate prescriptions in 2002 and 65.2% in 2009. The annual ratio of generic:brand fenofibrate use in the US from 2002 to 2008 ranged from 0:1 to 0.09:1, while the ratio in Canada steadily increased from 2005 to 2008 from 0.51:1 to 1.89:1. In the US, crude fenofibrate expenditures rose from $33.2 million/month in 2002 to $129.6 million/month in 2009, while those in Canada declined from $5.6 million/month to $5.1 million/month. Fibrate expenditures per 100,000 population were 3-fold higher in the US compared with Canada in 2009. Conclusions During the past decade, prescriptions for fibrates, particularly, fenofibrate, increased in the United States, while prescriptions for fibrates in Canada remained stable. PMID:21427374

Effects of El Niño on Summertime Ozone Air Quality in the Eastern United States

PubMed Central

Mickley, Loretta J.

2017-01-01

Abstract We investigate the effect of El Niño on maximum daily 8 h average surface ozone over the eastern United States in summer during 1980–2016. El Niño can influence the extratropical climate through the propagation of stationary waves, leading to (1) reduced transport of moist, clean air into the middle and southern Atlantic states and greater subsidence, reduced precipitation, and increased surface solar radiation in this region, as well as (2) intensified southerly flow into the south central states, which here enhances flux of moist and clean air. As a result, each standard deviation increase in the Niño 1 + 2 index is associated with an increase of 1–2 ppbv ozone in the Atlantic states and a decrease of 0.5–2 ppbv ozone in the south central states. These influences can be predicted 4 months in advance. We show that U.S. summertime ozone responds differently to eastern‐type El Niño events compared to central‐type events. PMID:29622852

Violent Death Rates: The US Compared with Other High-income OECD Countries, 2010.

Grinshteyn, Erin; Hemenway, David

2016-03-01

Violent death is a serious problem in the United States. Previous research showing US rates of violent death compared with other high-income countries used data that are more than a decade old. We examined 2010 mortality data obtained from the World Health Organization for populous, high-income countries (n = 23). Death rates per 100,000 population were calculated for each country and for the aggregation of all non-US countries overall and by age and sex. Tests of significance were performed using Poisson and negative binomial regressions. US homicide rates were 7.0 times higher than in other high-income countries, driven by a gun homicide rate that was 25.2 times higher. For 15- to 24-year-olds, the gun homicide rate in the United States was 49.0 times higher. Firearm-related suicide rates were 8.0 times higher in the United States, but the overall suicide rates were average. Unintentional firearm deaths were 6.2 times higher in the United States. The overall firearm death rate in the United States from all causes was 10.0 times higher. Ninety percent of women, 91% of children aged 0 to 14 years, 92% of youth aged 15 to 24 years, and 82% of all people killed by firearms were from the United States. The United States has an enormous firearm problem compared with other high-income countries, with higher rates of homicide and firearm-related suicide. Compared with 2003 estimates, the US firearm death rate remains unchanged while firearm death rates in other countries decreased. Thus, the already high relative rates of firearm homicide, firearm suicide, and unintentional firearm death in the United States compared with other high-income countries increased between 2003 and 2010.

China is the world’s largest emitter of anthropogenic air pollutants, and measurable amounts of Chinese pollution are transported via the atmosphere to other countries, including the United States. However, a large fraction of Chinese emissions is due to manufacture of goods for foreign consumption. Here, we analyze the impacts of trade-related Chinese air pollutant emissions on the global atmospheric environment, linking an economic-emission analysis and atmospheric chemical transport modeling. We find that in 2006, 36% of anthropogenic sulfur dioxide, 27% of nitrogen oxides, 22% of carbon monoxide, and 17% of black carbon emitted in China were associated with production of goods for export. For each of these pollutants, about 21% of export-related Chinese emissions were attributed to China-to-US export. Atmospheric modeling shows that transport of the export-related Chinese pollution contributed 3–10% of annual mean surface sulfate concentrations and 0.5–1.5% of ozone over the western United States in 2006. This Chinese pollution also resulted in one extra day or more of noncompliance with the US ozone standard in 2006 over the Los Angeles area and many regions in the eastern United States. On a daily basis, the export-related Chinese pollution contributed, at a maximum, 12–24% of sulfate concentrations over the western United States. As the United States outsourced manufacturing to China, sulfate pollution in 2006 increased in the western United States but decreased in the eastern United States, reflecting the competing effect between enhanced transport of Chinese pollution and reduced US emissions. Our findings are relevant to international efforts to reduce transboundary air pollution. PMID:24449863

Restoration treatments, such as revegetation with seeding or invasive species removal, have been applied on U.S. public lands for decades. Temporal trends in these management actions have not been extensively summarized previously, particularly in the southwestern United States where invasive plant species, drought, and fire have altered dryland ecosystems. We assessed long-term (1940–2010) trends in restoration using approximately 4,000 vegetation treatments conducted on Bureau of Land Management lands across the southwestern United States. We found that since 1940, the proportions of seeding and vegetation/soil manipulation (e.g. vegetation removal or plowing) treatments have declined, while the proportions of prescribed burn and invasive species treatments have increased. Treatments in pinyon-juniper and big sagebrush communities declined in comparison to treatments in desert scrub, creosote bush, and riparian woodland communities. Restoration-focused treatment objectives increased relative to resource extraction objectives. Species richness and proportion of native species used in seeding treatments also increased. Inflation-adjusted costs per area rose 750% for vegetation/soil manipulation, 600% for seeding, and 400% for prescribed burn treatments in the decades from 1981 to 2010. Seeding treatments were implemented in warmer and drier years when compared to the climate conditions of the entire study period and warmer and wetter years relative to several years before and after the treatment. These results suggest that treatments over a 70-year period on public lands in the southwestern United States are shifting toward restoration practices that are increasingly large, expensive, and related to fire and invasive species control.

The impact of dust storms on human health has been studied in the context of Asian, Saharan, Arabian, and Australian storms, but there has been no recent population-level epidemiological research on the dust storms in North America. The relevance of dust storms to public health is likely to increase as extreme weather events are predicted to become more frequent with anticipated changes in climate through the 21st century. We examined the association between dust storms and county-level non-accidental mortality in the United States from 1993 through 2005. Dust storm incidence data, including date and approximate location, are taken from the U.S. National Weather Service storm database. County-level mortality data for the years 1993-2005 were acquired from the National Center for Health Statistics. Distributed lag conditional logistic regression models under a time-stratified case-crossover design were used to study the relationship between dust storms and daily mortality counts over the whole United States and in Arizona and California specifically. End points included total non-accidental mortality and three mortality subgroups (cardiovascular, respiratory, and other non-accidental). We estimated that for the United States as a whole, total non-accidental mortality increased by 7.4% (95% CI: 1.6, 13.5; p = 0.011) and 6.7% (95% CI: 1.1, 12.6; p = 0.018) at 2- and 3-day lags, respectively, and by an average of 2.7% (95% CI: 0.4, 5.1; p = 0.023) over lags 0-5 compared with referent days. Significant associations with non-accidental mortality were estimated for California (lag 2 and 0-5 day) and Arizona (lag 3), for cardiovascular mortality in the United States (lag 2) and Arizona (lag 3), and for other non-accidental mortality in California (lags 1-3 and 0-5). Dust storms are associated with increases in lagged non-accidental and cardiovascular mortality. Citation: Crooks JL, Cascio WE, Percy MS, Reyes J, Neas LM, Hilborn ED. 2016.

Currently, about more than 253,000,000 automobiles and trucks, some are new, old, gas and electric, ply on the roads in the United States of America. Around the world, human activities and energy demand are the main sources for the air pollution and ozone depletion, causing dense haze, fog and smog especially during winter season in the country like China and India and also observed in different parts of the world. In recent years, automakers have been pushed by new governmental regulations and global expectations to create more fuel-efficient vehicles that burn less fossil fuels and create fewer harmful emissions. Automakers are exploring alternative fuel options such as hydrogen, natural gas, hybrids, and completely electric vehicles. Since the Nissan Leaf's introduction in 2010, fully electric vehicles have become widely produced and just fewer than 400,000 fully electric cars have been sold in the United States. Taking the influx of more fuel-efficient and alternative energy vehicles in the market into account, we have analyzed satellite and ground observed atmospheric pollution and greenhouse gases during 2009-2014 in the United States of America. Our results show that the increasing population of hybrid and fuel efficient vehicles have cut down the atmospheric pollution and greenhouse emissions in US in general, whereas in California the pollution level has increased as a result frequency of fog and haze events are seen during winter season. We will present a comparison of atmospheric pollution over US and California State in view of the increasing hybrid and fuel efficient vehicles.

We assessed changes in transit-associated walking in the United States from 2001 to 2009 and documented their importance to public health. We examined transit walk times using the National Household Travel Survey, a telephone survey administered by the US Department of Transportation to examine travel behavior in the United States. People are more likely to transit walk if they are from lower income households, are non-White, and live in large urban areas with access to rail systems. Transit walkers in large urban areas with a rail system were 72% more likely to transit walk 30 minutes or more per day than were those without a rail system. From 2001 to 2009, the estimated number of transit walkers rose from 7.5 million to 9.6 million (a 28% increase); those whose transit-associated walking time was 30 minutes or more increased from approximately 2.6 million to 3.4 million (a 31% increase). Transit walking contributes to meeting physical activity recommendations. Study results may contribute to transportation-related health impact assessment studies evaluating the impact of proposed transit systems on physical activity, potentially influencing transportation planning decisions.

Campylobacteriosis, a leading cause of foodborne illness in the United States, was not nationally notifiable until 2015. Data describing national patterns and trends are limited. We describe the epidemiology of Campylobacter infections in the United States during 2004-2012. We summarized laboratory-confirmed campylobacteriosis data from the Nationally Notifiable Disease Surveillance System, National Outbreak Reporting System, National Antimicrobial Resistance Monitoring System, and Foodborne Diseases Active Surveillance Network. During 2004-2012, 303520 culture-confirmed campylobacteriosis cases were reported. Average annual incidence rate (IR) was 11.4 cases/100000 persons, with substantial variation by state (range, 3.1-47.6 cases/100000 persons). IRs among patients aged 0-4 years were more than double overall IRs. IRs were highest among males in all age groups. IRs in western states and rural counties were higher (16.2/100000 and 14.2/100000, respectively) than southern states and metropolitan counties (6.8/100000 and 11.0/100000, respectively). Annual IRs increased 21% from 10.5/100000 during 2004-2006 to 12.7/100000 during 2010-2012, with the greatest increases among persons aged >60 years (40%) and in southern states (32%). The annual median number of Campylobacter outbreaks increased from 28 in 2004-2006 to 56 in 2010-2012; in total, 347 were reported. Antimicrobial susceptibility testing of isolates from 4793 domestic and 1070 travel-associated infections revealed that, comparing 2004-2009 to 2010-2012, ciprofloxacin resistance increased among domestic infections (12.8% vs 16.1%). During 2004-2012, incidence of campylobacteriosis, outbreaks, and clinically significant antimicrobial resistance increased. Marked demographic and geographic differences exist. Our findings underscore the importance of national surveillance and understanding of risk factors to guide and target control measures.

An interleaved, solid state expanded memory for a 100 MHz bandwidth waveform recorder is described. The memory development resulted in a significant increase in the storage capacity of a commercially available recorder. The motivation for the memory expansion of the waveform recorder, which is used to support in-flight measurement of the electromagnetic characteristics of lightning discharges, was the need for a significantly longer data window than that provided by the commercially available unit. The expanded recorder provides a data window that is 128 times longer than the commercial unit, while maintaining the same time resolution, by increasing the storage capacity from 1024 to 131 072 data samples. The expanded unit operates at sample periods as small as 10 ns. Sampling once every 10 ns, the commercial unit records for about 10 microseconds before the memory is filled, whereas, the expanded unit records for about 1300 microseconds. A photo of the expanded waveform recorder is shown.

The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest of cherries (Prunus spp.) (Rosaceae) in Europe and Asia. In 2016, R. cerasi was detected in Ontario, Canada, and in 2017 in New York State, USA, the first records of this pest in North America. The initial detections in Canada caused concern for the major cherry-growing states of Michigan, Washington, Oregon, and California in the United States. Establishment of R. cerasi in the United States could restrict cherry exports to other markets and increase costs needed for fly control, but it is unknown if R. cerasi can establish in U.S. commercial cherry regions. Here, we used the CLIMEX ecological niche model to determine the risk of establishment of R. cerasi in the United States and globally. Within the United States under a no-irrigation scenario, R. cerasi would establish in the East and West Coasts; however, under an irrigation scenario, its distribution would expand to the major cherry-growing regions in the interior of central and eastern Washington and in California. Results also showed that if introduced, R. cerasi would likely establish in eastern China, Japan, the Koreas, Australia, New Zealand, South America, South Africa, Mexico, and Canada. Host plant (Prunus spp. and Lonicera spp. [Caprifoliaceae]) presence, although not included in models, would affect fly establishment. Our results stress the importance of surveying for R. cerasi to prevent its spread and establishment within the United States and other countries.
