Landscape context is integral to population ecology, affecting a range of life history parameters, yet very little is known about how landscape structure influences many taxa. We sampled wetlands at 531 sites across 16 states in the eastern U.S. to examine the influence of landscape heterogeneity and anthropogenic land use on the relative abundance of freshwater turtles, one of the most endangered vertebrate clades in the world. Specifically, we aimed to understand how two components of landscape structure — compositional heterogeneity (wetland diversity) and configurational heterogeneity (wetland aggregation) — influence turtles with varying life history traits. Our results suggest that wetland configuration can modulate the relationship between relative abundance and anthropogenic land use. For example, spotted turtle (Clemmys guttata) was negatively associated with hay/pasture cover when wetlands were less aggregated, but this relationship subsided as aggregation increased. Notably, the way wetland aggregation modulated land use relationships varied across species. These results suggest that some anthropogenic cover types are not strictly positive or negative for certain species, but are instead context-dependent. Relative abundance also generally increased with higher wetland diversity, indicating the potential importance of landscape supplementation for turtles. We report a range of responses to roads that did not strictly correspond with well-established predictions related to body size and terrestrial activity patterns, including positive associations for certain species. Overall, our study supports the use of context-driven approaches to land use-related conservation and management decisions rather than blanket prescriptions, and further emphasizes that effective conservation of freshwater systems requires a landscape-level perspective. • Wetland configuration modulates the effect of land use on relative abundance. • Most turtle species displayed positive relationships with wetland diversity. • Effect of roads varied by species, with positive, negative, neutral relationships.

ABSTRACTTwo regional growth faults, the Golden Meadow Fault and the Lake Hatch Fault, were mapped in Terrebonne and Lafourche Parishes, Louisiana, utilizing over 3000 line kilometers of seismic data. The subcropping location of these faults identify major vegetation biozonations, new areas of wetland loss, and the position of transgressive lakes. The proposed mechanism governing these fault-related manifestations of subsidence involves the venting of fluid (and gas) from geopressured shales vertically up fault planes. Saline fluids and gases exiting a basin via growth faults provide accommodation space at depth, resulting in active, fault-induced subsidence in the down-thrown block. By contrast, areas along the fault trend where no fluids or gases were migrating would not result in an increase of accommodation space and would be considered inactive regarding fault-induced subsidence. The model that emerges is a growth fault trace that does not act in concert but more closely resembles a key-stepping system with sections alternating between active and inactive. These findings are relevant to the role of growth faults in subsidence-related coastal land loss and the vertical migration of hydrocarbons. [ABSTRACT FROM AUTHOR]

Different types of local currency have been generated by U.S. commodity grants since the inception of PI,. 480 in 1954. As an aid instrument, these local currencies have good points, but they also have serious deficiencies which can be traced to the inherent nature of soft currencies and their legal ownership. The differing economic effects of U.S.-owned and country-owned local currencies became significant when P.L. 480 became a major source of U.S.-owned local currencies. Before 1954, about 95 percent of local currency deposits were country, owned; since then, 66 percent of these de. posits have been U.S.-owned. The monetary and real effects of these two types of local currency are examined, as are the implications for U.S. aid policy. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Research investigating gastrointestinal (GI) symptoms from oil spill-related exposures is sparse. We evaluated prevalent GI symptoms among U.S. Coast Guard responders deployed to the Deepwater Horizon oil spill cleanup., Methods: Crude oil (via skin contact, inhalation, or ingestion routes), combined crude oil/oil dispersant exposures, other deployment exposures, deployment characteristics, demographics, and acute GI symptoms during deployment (i.e., nausea/vomiting, diarrhea, stomach pain, and constipation) were ascertained cross-sectionally via a post-deployment survey (median time between deployment end and survey completion 185 days) (N = 4885). Log-binomial regression analyses were employed to calculate prevalence ratios (PRs) and 95 % confidence intervals (CI). Effect modification was evaluated., Results: In adjusted models, responders in the highest (versus lowest) tertile of self-reported degree of skin contact to crude oil were more than twice as likely to report nausea/vomiting (PR=2.45; 95 %CI, 1.85-3.23), diarrhea (PR=2.40; 95 %CI, 2.00-2.88), stomach pain (PR=2.51; 95 %CI, 2.01-3.12), and constipation (PR=2.21; 95 %CI, 1.70-2.89). Tests for trend were statistically significant (p < 0.05). Results were similar for crude oil exposure via inhalation and ingestion. Higher PRs for all symptoms were found with combined crude oil/dispersant exposure than with crude oil exposure alone., Conclusions: These results indicate positive associations between self-reported crude oil and combined crude oil/oil dispersant exposures and acute GI symptoms., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Inc.)

- Abstract
Aim: Chronic stroke walking impairment is associated with high healthcare resource utilization (HCRU) costs. InTandem™ is a neurorehabilitation system that autonomously delivers a rhythmic auditory stimulation (RAS)-based intervention for the at-home rehabilitation of walking impairment in adults in the chronic phase of stroke recovery. This study was conducted to estimate the budget impact of InTandem in comparison with currently available intervention strategies for improvement of gait/ambulation in individuals with chronic stroke walking impairment. Methods & materials: A budget impact analysis (BIA) for InTandem was conducted based on a 1-million-member US third-party payer perspective over a 1-year time horizon. Key inputs for the budget impact model were: costs for each intervention strategy (InTandem, physical therapy, self-directed walking and no treatment), HCRU costs for persons with chronic stroke and anticipated HCRU cost offsets due to improvements in gait/ambulatory status as measured by self-selected comfortable walking speed (based on functional ability). In addition to the reference case analysis, a sensitivity analysis was conducted. Results: Based on the reference case, introduction of InTandem was projected to result in overall cost savings of $439,954 in one year. Reduction of HCRU costs (-$2,411,778) resulting from improved walking speeds with InTandem offset an increase in intervention costs (+$1,971,824). Demonstrations of cost savings associated with InTandem were robust and were consistently evident in nearly all scenarios evaluated in the sensitivity analysis (e.g., with increased/decreased patient shares, increased HCRU cost or increased InTandem rental duration). Conclusion: The InTandem system is demonstrated to improve walking and ambulation in adults in the chronic phase of stroke recovery after a five-week intervention period. The BIA predicts that introduction of InTandem will be associated with overall cost savings to the payer.

- Abstract
Background: Artificial intelligence (AI) and deep learning have shown great potential in streamlining clinical tasks. However, most studies remain confined to in silico validation in small internal cohorts, without external validation or data on real-world clinical utility. We developed a strategy for the clinical validation of deep learning models for segmenting primary non-small-cell lung cancer (NSCLC) tumours and involved lymph nodes in CT images, which is a time-intensive step in radiation treatment planning, with large variability among experts., Methods: In this observational study, CT images and segmentations were collected from eight internal and external sources from the USA, the Netherlands, Canada, and China, with patients from the Maastro and Harvard-RT1 datasets used for model discovery (segmented by a single expert). Validation consisted of interobserver and intraobserver benchmarking, primary validation, functional validation, and end-user testing on the following datasets: multi-delineation, Harvard-RT1, Harvard-RT2, RTOG-0617, NSCLC-radiogenomics, Lung-PET-CT-Dx, RIDER, and thorax phantom. Primary validation consisted of stepwise testing on increasingly external datasets using measures of overlap including volumetric dice (VD) and surface dice (SD). Functional validation explored dosimetric effect, model failure modes, test-retest stability, and accuracy. End-user testing with eight experts assessed automated segmentations in a simulated clinical setting., Findings: We included 2208 patients imaged between 2001 and 2015, with 787 patients used for model discovery and 1421 for model validation, including 28 patients for end-user testing. Models showed an improvement over the interobserver benchmark (multi-delineation dataset; VD 0·91 [IQR 0·83-0·92], p=0·0062; SD 0·86 [0·71-0·91], p=0·0005), and were within the intraobserver benchmark. For primary validation, AI performance on internal Harvard-RT1 data (segmented by the same expert who segmented the discovery data) was VD 0·83 (IQR 0·76-0·88) and SD 0·79 (0·68-0·88), within the interobserver benchmark. Performance on internal Harvard-RT2 data segmented by other experts was VD 0·70 (0·56-0·80) and SD 0·50 (0·34-0·71). Performance on RTOG-0617 clinical trial data was VD 0·71 (0·60-0·81) and SD 0·47 (0·35-0·59), with similar results on diagnostic radiology datasets NSCLC-radiogenomics and Lung-PET-CT-Dx. Despite these geometric overlap results, models yielded target volumes with equivalent radiation dose coverage to those of experts. We also found non-significant differences between de novo expert and AI-assisted segmentations. AI assistance led to a 65% reduction in segmentation time (5·4 min; p<0·0001) and a 32% reduction in interobserver variability (SD; p=0·013)., Interpretation: We present a clinical validation strategy for AI models. We found that in silico geometric segmentation metrics might not correlate with clinical utility of the models. Experts' segmentation style and preference might affect model performance., Funding: US National Institutes of Health and EU European Research Council., Competing Interests: Declaration of interests AH reports consultancy fees for Altis Labs; and owning stock in Altis Labs.

- Abstract
Introduction: Although disparities exist in patient access to and outcomes after total knee arthroplasty (TKA), there are limited data regarding the relationship between travel distance and patient demographics or postoperative complications., Methods: We identified patients who underwent TKA in Florida and New York between 2006 and 2014 using the Healthcare Cost and Utilization Project State Inpatient Databases. The American Hospital Association and UnitedStatesZipCodes.org Enterprise databases were further used to calculate distance traveled from patient population-weighted zip code centroid points to the hospitals at which they underwent TKA. Patients were grouped by travel distance: 25 to 50, 50 to 100, 100 to 500 miles, and greater than 500 miles. Patient demographic characteristics and postoperative outcomes were compared between the travel distance groups., Results: Older age, increased medical comorbidities, White race, Medicare insurance coverage, and living in zip codes with greater mean income levels were associated with greater travel distance (P < 0.001). There were no clinically significant relationships between various postoperative complications and distance traveled., Discussion: Certain demographic variables are associated with increased travel distance to undergo TKA. These relationships were most pronounced at the extremes of distance traveled (>500 miles). These differences may indicate that specific patient groups are either electing to or being forced to travel notable distances for orthopaedic care. Additional research is needed to determine the causative mechanisms underlying these findings., (Copyright © 2022 The Authors.

- Abstract
Objective: The objective of this study was to explore nurses' experiences and perceptions at selected United States (U.S.) healthcare sites during the COVID-19 pandemic., Background: The COVID-19 pandemic brought rapid changes to the healthcare community. While a few studies have examined the early pandemic experiences of nurses in China and Europe, nurses' experiences across the United States have remained relatively underexplored., Design: A qualitative study design was used., Methods: Using a constructivist grounded theory methodology and methods, we conducted eight focus groups across four hospital sites in the eastern, midwestern and western United States. Registered nurses with a minimum of six months' experience working in all clinical specialties were eligible. Forty-three nurses participated. Data were analysed iteratively using the constant comparative method. The COREQ guidelines supported the work and reporting of this study., Results: The nurses experiencing a pandemic (NEXPIC) grounded theory emerged positing associations between four interrelated themes: Challenges, Feelings, Coping and Ethics. Nurses reported Challenges associated with changes in the work environment, community and themselves. They expressed more negative than positive feelings. Nurses coped using self-care techniques, and teamwork within the healthcare organisation. Moral dilemmas, moral uncertainty, moral distress, moral injury and moral outrage were ethical issues associated with nurses' Challenges during the pandemic. Moral courage was associated with positive Coping., Conclusions: Awareness of frontline nurses' complex and interrelated needs may help healthcare organisations protect their human resources. This new theory provides preliminary theoretical support for future research and interventions to address the needs of frontline nurses., Relevance to Clinical Practice: Nurses face added distress as frontline at-risk caregivers. Interventions to promote nurses' ability to cope with personal and professional challenges from the pandemic and address ethical issues are needed to protect the nursing workforce. This study offers a new substantive theory that may be used to underpin future interventions., (© 2021 John Wiley & Sons Ltd.)

Objective: The objective of this multisite study was to explore the professional and personal experiences of US nurse managers (NMs) during the COVID-19 pandemic., Background: NMs are the most accessible and visible nurse leaders to the frontline staff during this pandemic., Methods: Thirty-nine NMs from 5 health systems across the US participated in focus groups in this qualitative study. Data were analyzed using a constant comparative method., Results: Three major themes were identified: challenges, feelings and emotions, and coping. Subthemes emerged within each major theme., Conclusion: NMs across the country accepted considerable responsibility at great professional and personal consequence during the pandemic. NMs experienced challenges, ethical dilemmas, and expressed negative emotions. As the usual coping strategies failed, NMs reported that they are considering alternative career choices. This work provided evidence to help senior leaders strategize about mechanisms for reducing managerial dissonance during times of stress., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
Introduction: There are data that disparities exist in access to total hip arthroplasty (THA). However, to date, no study has examined the relationship between distance traveled to undergo THA and patient demographic characteristics, such as race, insurance provider, and income level as well as postoperative outcomes., Methods: Data from the Healthcare Cost and Utilization Project, American Hospital Association, and the United States Postal Service were used to calculate the geographic distance between 211,806 patients' population-weighted zip code centroid points to the coordinates of the hospitals at which they underwent THA. We then used Healthcare Cost and Utilization Project data to examine the relationships between travel distance and both patient demographic indicators and postoperative outcomes after THA., Results: White patients traveled farther on average to undergo THA as compared with their non-White counterparts (17.38 vs 13.05 miles) (P < 0.0001). Patients with commercial insurance (17.19 miles) and Medicare (16.65 miles) traveled farther on average to receive care than did patients with Medicaid insurance coverage (14.00 miles) (P = 0.0001). Patients residing in zip codes in the top income quartile traveled farther to receive care (18.73 miles) as compared with those in the lowest income quartile (15.31 miles) (P < 0.0001). No clinically significant association was found between travel distance and adverse postoperative outcomes after THA., Discussion: Race, insurance provider, and zip code income quartile are associated with differences in the distance traveled to undergo THA. These findings may be indicative of underlying disparities in access to care across patient populations., (Copyright © 2022 The Authors.

- Abstract
Over the past few years, there has been a proliferation of artificial intelligence (AI) strategies, released by governments around the world, that seek to maximise the benefits of AI and minimise potential harms. This article provides a comparative analysis of the European Union (EU) and the United States' (US) AI strategies and considers (i) the visions of a 'Good AI Society' that are forwarded in key policy documents and their opportunity costs, (ii) the extent to which the implementation of each vision is living up to stated aims and (iii) the consequences that these differing visions of a 'Good AI Society' have for transatlantic cooperation. The article concludes by comparing the ethical desirability of each vision and identifies areas where the EU, and especially the US, need to improve in order to achieve ethical outcomes and deepen cooperation., (© 2021.

- Abstract
Background and Aims: In the USA, HBV is one of the leading causes of chronic liver disease and cirrhosis and is a major cause of liver cancer. We aimed to estimate the prevalence of past and present HBV infection, susceptibility to HBV infection, and vaccine-induced immunity to hepatitis B among the US population during 2013-2018., Approach and Results: Prevalence estimates and 95% CIs were analyzed using 2013-2018 data from the National Health and Nutrition Examination Survey. Serologic testing among noninstitutionalized persons aged ≥ 6 years was used for classifying persons as total hepatitis B core antibody (anti-HBc), indicative of current or previous (ever having had) HBV infection; HBsAg, indicative of current HBV infection; and antibody to ABsAg (anti-HBs), indicative of immunity attributable to hepatitis B vaccination. Persons who tested negative for anti-HBc, HBsAg, and anti-HBs were considered susceptible to HBV infection. Non-US-born residents accounted for 69.1% of the population with chronic HBV infection and were 9.1 times more likely to be living with chronic hepatitis B, compared with US-born persons. Among adults aged ≥ 25 years who resided in US households, an estimated 155.8 million persons (or 73.4%) were susceptible to HBV infection, and an estimated 45.4 million had vaccine-induced immunity to hepatitis B. Men who have sex with men (MSM) were 3.6 times more likely to have ever been infected with HBV; however, MSM were just as likely to have vaccine-induced immunity to hepatitis B as non-MSM., Conclusion: Despite increasing immune protection among young persons vaccinated after birth, the estimated prevalence of persons living with chronic hepatitis B in the USA has remained unchanged at 0.3% since 1999., (Published 2021.

- Abstract
It remains unclear how the seemingly ubiquitous use of the internet impacts user's offline personal relationships, particularly those that are romantic or sexual. Therefore, we conducted a national online survey to better understand the associations among internet use, sexual behavior, and adjustment called the Sexual Behaviors, Internet Use, and Psychological Adjustment Survey (SIPS). Here, we report patterns of sexual behavior in a sample of adults (N = 1987; ages 18-70) in the United States to establish its representativeness and consistency with similar recent surveys. We found age- and sex-related trends in oral, vaginal, and anal sex in terms of prevalence, frequency, number of partners, and age of initiation consistent with prior studies. We also detected differences in sexual behaviors based on relationship status and sexual orientation, but small and relatively few significant differences across racial and ethnic groups. The results confirm and expand upon trends identified in prior national surveys of sexual behavior, establishing the representativeness of the SIPS sample for use in future research examining the links among sexual behaviors and romantic relationships, internet use, and adjustment., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: The most recent estimates of the number of prevalent and incident sexually transmitted infections (STIs) in the United States were for 2008. We provide updated estimates for 2018 using new methods., Methods: We estimated the total number of prevalent and incident infections in the United States for 8 STIs: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes, human papillomavirus, sexually transmitted hepatitis B, and sexually transmitted HIV. Updated per-capita prevalence and incidence estimates for each STI were multiplied by the 2018 full resident population estimates to calculate the number of prevalent and incident infections. STI-specific estimates were combined to generate estimates of the total number of prevalent and incident STIs overall, and by sex and age group. Primary estimates are represented by medians, and uncertainty intervals are represented by the 25th (Q1) and 75th (Q3) percentiles of the empirical frequency distributions of prevalence and incidence for each STI., Results: In 2018, there were an estimated 67.6 (Q1, 66.6; Q3, 68.7) million prevalent and 26.2 (Q1, 24.0; Q3, 28.7) million incident STIs in the United States. Chlamydia, trichomoniasis, genital herpes, and human papillomavirus comprised 97.6% of all prevalent and 93.1% of all incident STIs. Persons aged 15 to 24 years comprised 18.6% (12.6 million) of all prevalent infections; however, they comprised 45.5% (11.9 million) of all incident infections., Conclusions: The burden of STIs in the United States is high. Almost half of incident STIs occurred in persons aged 15 to 24 years in 2018. Focusing on this population should be considered essential for national STI prevention efforts., Competing Interests: Conflict of Interest and Sources of Funding: The authors report no conflicts of interest., (Copyright © 2021 American Sexually Transmitted Diseases Association.

- Abstract
Background: We estimated the lifetime medical costs attributable to sexually transmitted infections (STIs) acquired in 2018, including sexually acquired human immunodeficiency virus (HIV)., Methods: We estimated the lifetime medical costs of infections acquired in 2018 in the United States for 8 STIs: chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes, human papillomavirus (HPV), hepatitis B, and HIV. We limited our analysis to lifetime medical costs incurred for treatment of STIs and for treatment of related sequelae; we did not include other costs, such as STI prevention. For each STI, except HPV, we calculated the lifetime medical cost by multiplying the estimated number of incident infections in 2018 by the estimated lifetime cost per infection. For HPV, we calculated the lifetime cost based on the projected lifetime incidence of health outcomes attributed to HPV infections acquired in 2018. Future costs were discounted at 3% annually., Results: Incident STIs in 2018 imposed an estimated $15.9 billion (25th-75th percentile: $14.9-16.9 billion) in discounted, lifetime direct medical costs (2019 US dollars). Most of this cost was due to sexually acquired HIV ($13.7 billion) and HPV ($0.8 billion). STIs in women accounted for about one fourth of the cost of incident STIs when including HIV, but about three fourths when excluding HIV. STIs among 15- to 24-year-olds accounted for $4.2 billion (26%) of the cost of incident STIs., Conclusions: Incident STIs continue to impose a considerable lifetime medical cost burden in the United States. These results can inform health economic analyses to promote the use of cost-effective STI prevention interventions to reduce this burden., Competing Interests: Conflicts of Interest: None declared., (Copyright © 2021 American Sexually Transmitted Diseases Association.

- Abstract
Background: Sexual transmission of hepatitis B virus (HBV) is common in the United States. In 2008, an estimated 50% of HBV infections were attributed to sexual transmission. Among 21,600 acute infections that occurred in 2018, the proportion attributable to sexual transmissions is unknown., Methods: Objectives of this study were to estimate incidence and prevalence of hepatitis B attributable to sexual transmission among the US population 15 years and older for 2013 to 2018. Incidence estimates were calculated for confirmed cases submitted to Centers for Disease Control and Prevention from 14 states. A hierarchical algorithm defining sexually transmitted acute HBV infections as the absence of injection drug use among persons reporting sexual risk factors was applied to determine proportion of hepatitis B infections attributable to sexual transmission nationally. National Health and Nutrition Examination Survey public use data files were analyzed to calculate prevalence estimates of hepatitis B among US households and proportion attributed to sexual transmission was conservatively determined for HBV-infected non-US-born Americans who migrated from HBV endemic countries., Results: During 2013 to 2018, an estimated 47,000 (95% confidence interval [CI], 27,000-116,000) or 38.2% of acute HBV infections in the United States were attributable to sexual transmission. During 2013 to 2018, among the US noninstitutionalized population, an estimated 817,000 (95% CI, 613,000-1,100,000) persons 15 years and older were living with hepatitis B, with an estimated 103,000 (95% CI, 89,000-118,000) infections or 12.6% attributable to sexual transmission., Conclusions: These findings provide evidence sexually transmitted HBV infections remain a public health problem and underscore the importance of interventions to improve vaccination among at-risk populations., Competing Interests: Conflicts of Interest and Sources of Funding: None declared., (Copyright © 2021 American Sexually Transmitted Diseases Association.

- Abstract
Objective: To provide a current perspective concerning dental personnel sensitivity to methacrylate materials., Overview: Methacrylate related sensitivity and allergies are currently beyond traditional thoughts concerning denture base resins and methyl methacrylate provisional materials. Methacrylates are now ubiquitous in current dental practice and dental personnel should be aware that dental adhesives contain potent sensitizers that may also cross-sensitize individuals to other methacrylates not experienced. The growing sensitivity to 2-hydroxyethyl methacrylate (HEMA) has been described to be epidemic in nature due to the artificial nail industry with dental patients and dental personnel may be more susceptible to dental methacrylate sensitization. While contact dermatitis remains the most prevalent methacrylate-related clinical presentation, respiratory complications and asthma are increasing associated with methacrylate exposure. While additional personal protective equipment (PPE) is thought to be first protective choice, the National Institute for Occupational Safety and Health (NIOSH) considers PPE overall largely ineffective and should be considered only as a last resort., Conclusion: Dental personnel need to be more aware of methacrylate sources and use workplace control measures to limit methacrylate exposures to both dental personnel and patients., Clinical Significance: Sensitivity to methacrylate materials is a growing dental workplace major concern and dental personnel should be aware of both the methacrylate content of current materials and the products that contain ingredients with the most sensitization potential., (© 2020 Wiley Periodicals LLC.)

- Abstract
Background: Functional tricuspid regurgitation (FTR) secondary to left-sided heart disease may lead to poor quality of life and reduced long-term survival. This study evaluated clinical and functional outcomes of patients undergoing tricuspid valve (TV) repair using a rigid three-dimensional ring (Contour 3D, Medtronic) concomitant with another procedure., Methods: From September 2011 to July 2015, 112 patients (mean age 70.9 ± 9.0 years) were enrolled at 10 centers in Europe, Israel, and the United States. Inclusion criteria were FTR ≥ moderate and/or tricuspid annular diameter (TAD) ≥ 40 mm. Echocardiography was planned before surgery and at discharge with echocardiographic and clinical follow-ups performed 6 months postoperatively., Results: Three fourths (74.4%) of patients had higher than moderate TR. Mean TAD was 41.0 ± 7.3 mm; 61.7% of patients were in the New York Heart Association (NYHA) class III/IV. The most common concomitant procedure was mitral valve repair (57 patients, 53.3%). The 30-day mortality rate was 0.9% ( n = 1). The mean EuroSCORE II was 8.9 ± 8.4% (median: 5.9%; interquartile range: 3.5-11.5%). The observed to expected ratio (O/E) based on the median was 0.1. Six deaths occurred during follow-up (three cardiac related). Mean implanted ring size was 30.3 ± 2.7. At 6 months, 94.4% of patients showed ≤ mild TR, and 92.0% were in NYHA class I/II ( p < 0.001 vs baseline for both). Mean pressure gradient across the TV was 2.0 ± 1.1 mm Hg; leaflet coaptation length was 7.5 ± 3.3 mm., Conclusion: The Contour 3D annuloplasty ring used for treatment of FTR substantially reduced TR for up to 6 postoperative months with low mean pressure gradients across the TV and significant improvement in NYHA class., Registration: www.ClinicalTrials.gov, NCT01532921., Competing Interests: Ralf Guenzinger has no conflicts of interest to declare.

- Abstract
Background: Mortality associated with hepatitis C virus (HCV) has been well-documented nationally, but an examination across regions and jurisdictions may inform health-care planning., Methods: To document HCV-associated deaths sub-nationally, we calculated age-adjusted, HCV-associated death rates and compared death rate ratios (DRRs) for 10 US regions, 50 states, and Washington, D.C., using the national rate and described rate changes between 2016 and 2017 to determine variability. We examined the mean age at HCV-associated death, and rates and proportions by sex, race/ethnicity, and birth year., Results: In 2017, there were 17 253 HCV-associated deaths, representing 4.13 (95% confidence interval [CI], 4.07-4.20) deaths/100 000 standard population, in a significant, 6.56% rate decline from 4.42 in 2016. Age-adjusted death rates significantly surpassed the US rate for the following jurisdictions: Oklahoma; Washington, D.C.; Oregon; New Mexico; Louisiana; Texas; Colorado; California; Kentucky; Tennessee; Arizona; and Washington (DRRs, 2.87, 2.77, 2.24, 1.62, 1.57, 1.46, 1.36, 1.35, 1.35, 1.35, 1.32, and 1.32, respectively; P < .05). Death rates ranged from a low of 1.60 (95% CI, 1.07-2.29) in Maine to a high of 11.84 (95% CI, 10.82-12.85) in Oklahoma. Death rates were highest among non-Hispanic (non-H) American Indians/Alaska Natives and non-H Blacks, both nationally and regionally. The mean age at death was 61.4 years (range, 56.6 years in West Virginia to 64.1 years in Washington, D.C.), and 78.6% of those who died were born during 1945-1965., Conclusions: In 2016-2017, the national HCV-associated mortality declined but rates remained high in the Western and Southern regions and Washington, D.C., and among non-H American Indians/Alaska Natives, non-H Blacks, and Baby Boomers. These data can inform local prevention and control programs to reduce the HCV mortality burden., (Published by Oxford University Press for the Infectious Diseases Society of America 2019.)

- Abstract
Objective: A national estimate of births to hepatitis B surface antigen (HBsAg)-positive women can help public health programs plan surveillance, educational, and outreach activities to improve identification and management of at-risk women and infants. Stratifying mothers by country of birth allows for the application of region-specific HBsAg prevalence estimates, which can more precisely estimate the number of at-risk infants. The objective of our study was to estimate the number of births to HBsAg-positive women in the United States with more granularity than previous models., Methods: We developed a model that incorporated maternal country of birth (MCOB) and updated HBsAg prevalence estimates. We assessed birth certificate data by MCOB, and we stratified US-born mothers by race/ethnicity, US territory-born mothers by territory, and non-US-born mothers by region. We multiplied and summed data in each subcategory by using HBsAg prevalence estimates calculated from the 2009-2014 National Health and Nutrition Examination Surveys or Perinatal Hepatitis B Prevention Program. We compared the findings of our MCOB model with a race/ethnicity model., Results: In 2015, an estimated 20 678 infants were born to HBsAg-positive women in the United States, representing 0.5% of all births. Births to US-born and non-US-born women comprised 77.2% and 21.5% of all births, respectively, and 40.1% and 57.9% of estimated births to HBsAg-positive women, respectively. The estimated contribution of births to HBsAg-positive women varied by MCOB region, from 4 (0.03%) infants born to women from Australia/Oceania to 5795 (28.0%) infants born to women from East Asia. Our MCOB model estimated 5666 fewer births to HBsAg-positive women than did the race/ethnicity model., Conclusions: As global vaccine programs reduce HBsAg prevalence, the MCOB model can incorporate evolving HBsAg prevalence estimates for women from various regions of the world.

- Abstract
Aims: This article analyzes the digital childhood vaccination information network for vaccine-hesitant parents. The goal of this study was to explore the structure and influence of vaccine-hesitant content online by generating a database and network analysis of vaccine-relevant content., Method: We used Media Cloud, a searchable big-data platform of over 550 million stories from 50,000 media sources, for quantitative and qualitative study of an online media sample based on keyword selection. We generated a hyperlink network map and measured indegree centrality of the sources and vaccine sentiment for a random sample of 450 stories., Results: 28,122 publications from 4,817 sources met inclusion criteria. Clustered communities formed based on shared hyperlinks; communities tended to link within, not among, each other. The plurality of information was provaccine (46.44%, 95% confidence interval [39.86%, 53.20%]). The most influential sources were in the health community (National Institutes of Health, Centers for Disease Control and Prevention) or mainstream media ( New York Times); some user-generated sources also had strong influence and were provaccine (Wikipedia). The vaccine-hesitant community rarely interacted with provaccine content and simultaneously used primary provaccine content within vaccine-hesitant narratives., Conclusion: The sentiment of the overall conversation was consistent with scientific evidence. These findings demonstrate an online environment where scientific evidence online drives vaccine information outside of the vaccine-hesitant community but is also prominently used and misused within the robust vaccine-hesitant community. Future communication efforts should take current context into account; more information may not prevent vaccine hesitancy.

- Abstract
Unlabelled: The number of persons with chronic hepatitis B virus (HBV) infection in the United States is affected by diminishing numbers of young persons who are susceptible because of universal infant vaccination since 1991, offset by numbers of HBV-infected persons migrating to the United States from endemic countries. The prevalence of HBV infection was determined by serological testing and analysis among noninstitutionalized persons age 6 years and older for: antibody to hepatitis B core antigen (anti-HBc), indicative of previous HBV infection; hepatitis B surface antigen (HBsAg), indicative of chronic (current) infection; and antibody to hepatitis B surface antigen (anti-HBs), indicative of immunity from vaccination. These prevalence estimates were analyzed in three periods of the National Health and Nutrition Examination Survey (NHANES): 1988-1994 (21,260 persons); 1999-2008 (29,828); and 2007-2012 (22,358). In 2011-2012, for the first time, non-Hispanic Asians were oversampled in NHANES. For the most recent period (2007-2012), 3.9% had anti-HBc, indicating approximately 10.8 (95% confidence interval [CI]: 9.4-12.2) million noninstitutionalized U.S. residents having ever been infected with HBV. The overall prevalence of chronic HBV infection has remained constant since 1999: 0.3% (95% CI: 0.2-0.4), and since 1999, prevalence of chronic HBV infection among non-Hispanic blacks has been 2- to 3-fold greater than the general population. An estimated 3.1% (1.8%-5.2%) of non-Hispanic Asians were chronically infected with HBV during 2011-2012, which reflects a 10-fold greater prevalence than the general population. Adjusted prevalence of vaccine-induced immunity increased 16% since 1999, and the number of persons (mainly young) with serological evidence of vaccine protection from HBV infection rose from 57.8 (95% CI: 55.4-60.1) million to 68.5 (95% CI: 65.4-71.2) million., Conclusion: Despite increasing immune protection in young persons vaccinated in infancy, an analysis of chronic hepatitis B prevalence in racial and ethnic populations indicates that during 2011-2012, there were 847,000 HBV infections (which included ~400,000 non-Hispanic Asians) in the noninstitutionalized U.S. POPULATION., (Published 2015.

- Abstract
We reviewed news reports of hepatitis A virus (HAV)-infected food handlers in the United States from 1993 to 2011 using the LexisNexis® search engine. Using U.S. news reports, we identified 192 HAV-infected food handlers who worked while infectious; of these HAV-infected individuals, 34 (18%) transmitted HAV to restaurant patrons. News reports of HAV-infected food handlers declined from 1993 to 2011. This analysis suggests that universal childhood vaccination contributed to the decrease in reports of HAV-infected food handlers, but mandatory vaccination of this group is unlikely to be cost-effective.

- Abstract
Background: An estimated 20 000 new hepatitis B virus (HBV) infections occur each year in the United States. We describe the results of enhanced surveillance for acute hepatitis B at 7 federally funded sites over a 6-year period., Methods: Health departments in Colorado, Connecticut, Minnesota, Oregon, Tennessee, 34 counties in New York state, and New York City were supported to conduct enhanced, population-based surveillance for acute HBV from 2006 through 2011. Demographic and risk factor data were collected on symptomatic cases using a standardized form. Serum samples from a subset of cases were also obtained for molecular analysis., Results: In the 6-year period, 2220 acute hepatitis B cases were reported from the 7 sites. For all sites combined, the incidence rate of HBV infection declined by 19%, but in Tennessee incidence increased by 90%, mainly among persons of white race/ethnicity and those aged 40-49 years. Of all reported cases, 66.1% were male, 57.1% were white, 58.4% were aged 30-49 years, and 60.1% were born in the United States. The most common risk factor identified was any drug use, notably in Tennessee; healthcare exposure was also frequently reported. The most common genotype for all reported cases was HBV genotype A (82%)., Conclusions: Despite an overall decline in HBV infection, attributable to successful vaccination programs, a rise in incident HBV infection related to drug use is an increasing concern in some localities., (Published by Oxford University Press on behalf of the Infectious Diseases Society of America 2015.

- Abstract
Context: Employee performance evaluation motivates and rewards exceptional individual performance that advances the achievement of organizational goals. The Centers for Disease Control and Prevention (CDC) and its operating units evaluate employee performance annually and reward exceptional performance with a cash award or quality step increase in pay. A summary performance rating (SPR) of "exceptional" indicated personal achievements in 2011 that were beyond expectations described in the employee's performance plan., Objective: To determine whether personal attributes and job setting of civil service employees were associated with an exceptional SPR in National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) in 2011., Design: Data from the CDC 2011 performance management database collected in 2012 were analyzed in 2013 to identify SPR, personal attributes, and job settings of full-time civil service employees. Multivariate logistic regression controlled for confounding and stratified analysis detected effect modifiers of the association between receiving an exceptional SPR in 2011 and gender, race/ethnicity, education, job location, job series, grade level, years in grade, years of federal service, supervisory role, and NCHHSTP division., Results: Among the 1037 employees, exceptional SPR was independently associated with: female gender (adjusted odds ratio: 1.7 [1.3, 2.3]), advanced degrees (doctorate: 1.7 [1.1, 2.5] master's: [1.1, 2.0]), headquarters location (2.8 [1.9, 4.1]), higher pay grade (3.3 [2.4, 4.5]) and years in grade (0-1 years: 1.7 [1.3, 2.4]; 2-4 years: 1.5 [1.1, 2.0]), division level (Division A: 5.0 [2.5, 9.9]; Division B: 5.5 [3.5, 8.8]), and supervisory status (at a lower-pay grade) (odds ratio: 3.7 [1.1, 11.3])., Conclusions: Exceptional SPR is independently associated with personal employee attributes and job settings that are not modifiable by interventions designed to improve employee performance based on accomplishments.

- Abstract
Objectives: Because only a fraction of patients with acute viral hepatitis A, B, and C are reported through national surveillance to the Centers for Disease Control and Prevention, we estimated the true numbers., Methods: We applied a simple probabilistic model to estimate the fraction of patients with acute hepatitis A, hepatitis B, and hepatitis C who would have been symptomatic, would have sought health care tests, and would have been reported to health officials in 2011., Results: For hepatitis A, the frequencies of symptoms (85%), care seeking (88%), and reporting (69%) yielded an estimate of 2730 infections (2.0 infections per reported case). For hepatitis B, the frequencies of symptoms (39%), care seeking (88%), and reporting (45%) indicated 18 730 infections (6.5 infections per reported case). For hepatitis C, the frequency of symptoms among injection drug users (13%) and those infected otherwise (48%), proportion seeking care (88%), and percentage reported (53%) indicated 17 100 infections (12.3 infections per reported case)., Conclusions: These adjustment factors will allow state and local health authorities to estimate acute hepatitis infections locally and plan prevention activities accordingly.

- Abstract
In 2009, the CDC National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) initiated the online, interactive NCHHSTP Atlas. The goal of the Atlas is to strengthen the capacity to monitor the diseases overseen by NCHHSTP and to illustrate demographic, spatial, and temporal variation in disease patterns. The Atlas includes HIV, AIDS, viral hepatitis, sexually transmitted disease, and tuberculosis surveillance data, and aims to provide a single point of access to meet the analytical and data dissemination needs of NCHHSTP. To accomplish this goal, an NCHHSTP-wide Data Harmonization Workgroup reviewed surveillance data collected by each division to harmonize the data across diseases, allowing one to query data and generate comparable maps and tables via the same user interface. Although we were not able to harmonize all data elements, data standardization is necessary and work continues toward that goal.

Objectives: To compare three aspects of Crohn's disease (CD) between African Americans and Caucasians: (1) demographic data and environmental factors affecting CD susceptibility, (2) disease presentation and clinical course, and (3) genetic susceptibility via the use of single nucleotide polymorphism (SNP) data for inflammatory bowel disease (IBD) susceptibility loci., Methods: Clinical data and peripheral blood were obtained from 1032 patients (554 CD patients and 478 controls) derived from a clinically well-defined university-based medical and surgical digestive disease practice and included those who were diagnosed with IBD. Genomic DNA was extracted and polymerase chain reaction (PCR) amplification and genotyping were performed for 11 SNPs, including the NOD2, IL-23r, OCTN 1, and the IGR gene variants., Results: A total of 554 patients with CD were included in this study: 53 African Americans (10%), 485 Caucasians (87%), and 15 of other races (3%). The strongest demographic predictor of CD in African American patients was a family history of IBD. Ileocolic disease (L3) was the most common site involved in both African Americans and Caucasians, while the penetrating phenotype (B3) was the most common CD disease behavior in both races. Genotype association analysis showed a significant association between 2 IL23r gene SNPs and CD susceptibility in African Americans (p = .016 and .028, respectively)., Conclusion: We believe this study is the first to report on genotype-phenotype associations in African American CD patients and compare findings to Caucasian CD patients within the same geographic area. We found no association between NOD2 gene SNPs and CD susceptibility in African Americans patients (p > .05).

- Abstract
Background: Crohn's disease (CD) and ulcerative colitis (UC), the two main types of inflammatory bowel disease (IBD), are multifactorial conditions of unknown etiology. The objective of this study is to examine the combined gene-environment interactions influencing IBD susceptibility in a well-defined Caucasian cohort in rural mid-America., Methods: Patients were diagnosed to have CD or UC using conventional radiologic, endoscopic, and/or histopathologic findings. Histological diagnosis was made by a single specialist gastrointestinal pathologist with a particular interest in IBD. Information regarding cigarette smoke exposure was obtained by administration of the Behavioral Risk Factor Surveillance System Survey (BRFSS) to all patients. Genomic DNA was extracted from peripheral blood leukocytes, and polymerase chain reaction (PCR) amplification and genotyping were performed for 11 Single Nucleotide Polymorphisms (SNP) in NOD2, IL23r, OCTN1 genes along with IGR., Results: Our cohort consists of 1196 patients: 435 controls, 485 CD patients, and 276 UC patients. Only patients with genotype data for at least 7 of 11 SNPs were included in our data analysis. The control groups for all 11 SNPs were in Hardy-Weinberg Equilibrium. In genotype-association SNP analysis, all NOD2 SNPs (rs5743293, rs2066844, rs2066845) and the IL23r SNP (rs11465804) showed a significant association to IBD (p < 0.03). A multiple gene-interaction analysis showed an association between NOD2 and IL23r with UC (p = 0.04). There were no associations between any OCTN1 and IGR SNPs and IBD in this cohort. A multivariable logistic regression analysis showed that female gender, "current" or "former" smoking status, family history of IBD, and NOD2 SNP minor alleles were associated with CD., Conclusion: IBD remains to be challenging to properly diagnose, characterize, and treat. Our study proposes a combined genetic, phenotypic, and environmental approach in an attempt to better understand IBD. Previously demonstrated associations between OCTN1 and IGR and IBD were not confirmed.

- Abstract
Background: Knowledge of the genotypic distribution of hepatitis B virus (HBV) facilitates epidemiologic tracking and surveillance of HBV infection as well as prediction of its disease burden. In the United States, HBV genotyping studies have been conducted for chronic but not acute hepatitis B., Methods: Serum samples were collected from patients with acute hepatitis B cases reported from the 6 counties that participated in the Sentinel Counties Study of Acute Viral Hepatitis from 1999 through 2005. Polymerase chain reaction followed by nucleotide sequencing of a 435-base pair segment of the HBV S gene was performed, and the sequences were phylogenetically analyzed., Results: Of 614 patients identified with available serum samples, 75% were infected with genotype A HBV and 18% were infected with genotype D HBV. Thirty-two percent of genotype A sequences constituted a single subgenotype A2 cluster. The odds of infection with genotype A (vs with genotype D) were 5 times greater among black individuals than among Hispanic individuals (odds ratio [OR], 5; 95% confidence interval [CI], 2.3-10.7). The odds of infection with genotype A were 49, 8, and 4 times greater among patients from Jefferson County (Alabama), Pinellas County (Florida), and San Francisco (California), respectively, than among those living in Denver County (Colorado). Genotype A was less common among recent injection drug users than it was among non-injection drug users (OR, 0.2; 95% CI, 0.1-0.4)., Conclusions: HBV genotype distribution was significantly associated with ethnicity, place of residence, and risk behavior.

- Abstract
Objective: In this study, we build on the previous findings of increased diabetes prevalence among American Indian/Alaska Native (AI/AN) young adults, by studying the rate at which annual prevalence estimates of diagnosed diabetes increased from 1994 to 2007., Design and Setting: For this study, BRFSS data for 1994-2007 from the 50 states, District of Columbia, Puerto Rico, Guam, and the Virgin Islands were analyzed., Participants: Only non-institutionalized adults aged 18 years and older were eligible to participate in the Behavioral Risk Factor Surveillance System survey., Main Outcome Measures: To examine the existence and strength of a trend, we analyzed plots and Spearman's rank correlation coefficients of annual prevalence estimates for each group of young adults. Mantel-Haenszel tests were employed to study the relationship of diagnosed diabetes prevalence and race (AI/ AN, non-Hispanic White), while controlling for the time periods 1994-2000 and 2001-2007. To quantify increases in the disparity of diagnosed diabetes prevalence and race (AI/ AN, non-Hispanic White), odds risk ratio estimates were employed to approximate corresponding prevalence ratio estimates for the time periods 1994-2000 and 2001-2007., Results: Employing Spearman's test for trend resulted in observing, during 1994-2007, statistically significant increasing trends in the annual prevalence estimates of diagnosed diabetes among AI/AN and non-Hispanic White young adults. AI/AN young adults, on average, were 1.7 (95% CI; [1.12, 2.63]) times more likely than non-Hispanic White young adults to be diagnosed with diabetes during 1994-2000 and 2.5 (95% CI; [1.93, 3.32]) times more likely during 2001-2007., Conclusion: The findings in this study suggests that the disparity in the estimated prevalence of diagnosed diabetes between AI/AN and NHW young adults widened steadily from 2001 to 2007.

- Abstract
Problem: Behavioral risk factors such as smoking, poor diet, physical inactivity, and excessive drinking are linked to the leading causes of death in the United States. Controlling these behavioral risk factors and using preventive health services (e.g., influenza vaccinations and cholesterol screenings) can reduce morbidity and mortality in the U.S. population substantially. Continuous monitoring both of health behaviors and of the use of preventive services is essential for developing health promotion activities, intervention programs, and health policies at the state, city, and county level., Reporting Period Covered: January--December 2006., Description of the System: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, random-digit--dialed telephone survey of the noninstitutionalized U.S. population aged >/=18 years. BRFSS collects data on health-risk behaviors and use of preventive health services related to the leading causes of death and disability in the United States. This report presents results for 2006 for all 50 states, DC, Puerto Rico, the U.S. Virgin Islands, 145 selected metropolitan and micropolitan statistical areas (MMSAs), and 234 corresponding counties., Results: Prevalence estimates of risk behaviors, chronic conditions, and the use of preventive services varied substantially by state and territory, MMSA, and county. In 2006, the estimated prevalence of fair or poor health ranged from 11% to 33% for states and territories, from 8% to 24% for MMSAs, and from 5% to 24% for counties. The estimated prevalence of health-care coverage ranged from 61% to 96% for states and territories, MMSAs, and counties. The estimated prevalence of teeth extraction among adults aged >/=65 years was lowest in Hawaii (10%) and highest in Kentucky (39%) and West Virginia (41%). The estimated prevalence of activity limitation as a result of physical, mental, or emotional problems ranged from 10% to 28% for states and territories, from 13% to 36% for MMSAs, and from 11% to 29% for counties. The estimated prevalence of adults who had a recent routine checkup ranged from 45% to 81% for states and territories, MMSAs, and counties. The estimated prevalence of annual influenza vaccination among adults aged >/=65 years was lowest in Puerto Rico (33%) and highest in Colorado (76%). The estimated prevalence of pneumococcal vaccination among older adults ranged from 30% to 75% for states and territories, from 52% to 80% for MMSAs, and from 42% to 82% for counties. The estimated prevalence of sigmoidoscopy/colonoscopy among adults aged >/=50 years ranged from 38% to 84% for states and territories, MMSAs, and counties. The estimated prevalence among adults aged >/=50 years who had a blood stool test during the preceding 2 years was lowest in Puerto Rico (5%) and highest in DC and Maine (33%). The estimated prevalence among women having a Papanicolaou (Pap) test during the preceding 3 years ranged from 72% to 89% for states and territories, from 75% to 94% for MMSAs, and from 75% to 95% in counties. The estimated prevalence among women aged >/=40 years having a mammogram during the preceding 2 years ranged from 60% to 89% for states and territories, MMSAs, and counties. The estimated prevalence among men aged >/=40 years who had a prostate-specific antigen (PSA) test during the preceding 2 years was lowest in Hawaii (40%) and highest in Puerto Rico (66%). The estimated prevalence of cigarette smoking ranged from 9% to 29% for states and territories and from 6% to 31% for MMSAs and counties. The estimated prevalence of binge drinking was lowest in Kentucky and Tennessee (9%) and highest in Wisconsin (24%). The estimated prevalence of leisure-time physical inactivity ranged from 11% to 41% for states and territories, MMSAs, and counties. Seat belt use was lowest in North and South Dakota (58%) and highest in California, Hawaii, and Washington (92%). The estimated prevalence among adults who were overweight ranged from 32% to 40% for states and territories, from 31% to 45% for MMSAs, and from 24% to 49% for counties. The estimated prevalence of obesity ranged from 10% to 46% for states and territories, MMSAs, and counties. The estimated current asthma prevalence ranged from 3% to 14% for states and territories, MMSAs, and counties. The estimated prevalence of diabetes ranged from 2% to 13% for states and territories, MMSAs, and counties. The estimated prevalence of coronary heart disease among adults aged >/=45 years ranged from 5% to 20% for states and territories. The estimated prevalence of a history of stroke history among adults aged >/=45 years ranged from 2% to 10% for states and territories, MMSAs, and counties., Interpretation: This report indicates that substantial variations in health-risk behaviors, chronic diseases and conditions, and the use of preventive health services exist among adults from state to state and within states and underscores the continued need for prevention and health promotion activities at the local, state, and federal levels., Public Health Action: Healthy People 2010 objectives have been established to monitor health behaviors and the use of preventive health services. Local and state health departments and federal agencies use BRFSS data to measure progress toward achieving national and local health objectives. Continued surveillance is needed to design, implement, and evaluate public health policies and programs that can lead to a reduction in morbidity and mortality from the effects of health-risk behaviors and subsequent chronic conditions.

- Abstract
Problem: Continuous monitoring of behaviors that increase the risk for chronic diseases and use of preventive practices are essential for the development, implementation, and evaluation of health promotion programs and policies, and other intervention strategies to prevent morbidity and mortality. Data from states/territories, selected metropolitan and micropolitan statistical areas (MMSAs), and counties provide the impetus for policymakers and other stakeholders to develop and promote the improvement of their community's overall health status., Reporting Period Covered: Data in this report were collected during January 1-December 31, 2004, from states/territories, MMSAs, and counties that participated in the 2004 Behavioral Risk Factor Surveillance System (BRFSS)., Description of the System: BRFSS is an ongoing, state-based, random-digit--dialed telephone survey that employs a multistage cluster design. BRFSS collects information on health risk behaviors and preventive health practices related to the leading causes of death from the U.S. civilian, noninstitutionalized population aged > or =18 years. During 2004, a total of 49 states, the District of Columbia (DC), Puerto Rico, and the U.S. Virgin Islands participated in BRFSS. Among these states and territories, completed surveys were collected from a selection of 134 MMSAs and 199 counties., Results: Prevalence of high-risk behaviors for chronic diseases, awareness of specific medical conditions, screening for certain cancers, and use of preventive health services varied substantially by state/territory, MMSA, and county. The proportion of the population that achieved Healthy People 2010 (HP 2010) objectives also varied by state/territory, MMSA, and county. In 2004, HP 2010 objectives for 100% health-care coverage and vaccination for pneumonia and influenza among persons aged > or =65 years were not achieved by any state/territory, MMSA, or county. Twelve states/territories, 47 MMSAs, and 74 counties achieved the HP 2010 objective of < or =20% of adults engaged in no leisure-time physical activity or exercise. The HP 2010 objective to reduce the proportion of adults who currently smoke cigarettes to < or =12% was achieved by two states/territories, four MMSAs, and six counties. One MMSA and one county achieved the HP 2010 target of < or =6% who engage in binge drinking during the month preceding the survey. The HP 2010 target of < or =15% of adults who are obese was obtained by one MMSA and eight counties. The HP 2010 objective to reduce the proportion to <20% for older adults who have had all of their natural teeth extracted was achieved by 23 states/territories, 51 MMSAs, and 45 counties. The HP 2010 target for adults aged > or =50 years who have ever received a sigmoidoscopy is 50%. BRFSS measured both sigmoidoscopy and colonoscopy. Using this measure, 38 states, 110 MMSAs, and 154 counties achieved the 50% goal. Four counties achieved the HP 2010 objective of 50% for adults who received a blood stool test within the previous 2 years. The HP 2010 objective to increase the proportion of women aged > or =18 years who had a Papanicolaou (Pap) test within the preceding 3 years is 90%. Twenty-four MMSAs and 49 counties achieved this objective. The HP 2010 objective for women aged > or =40 years who have received a mammogram within the preceding 2 years is 70%. Thirty-nine states, 112 MMSAs, and 168 counties achieved the objective. This report includes several risk behaviors and conditions that, although not included in HP 2010 goals, are important public health problems. These include self-reported fair-to-poor health status, heavy alcohol consumption, asthma, diabetes, and prostate cancer screening. The 2004 BRFSS data indicate great variability in the prevalence of self-reported fair-to-poor health status (5.7%-34.8%) and use of prostate cancer screening (34.7%-65.2%) by states/territories, MMSAs, and counties. Among these areas, the prevalence of current asthma ranged from 4.1% to 12.4%, and the prevalence of diabetes ranged from 3.2% to 12.5%., Interpretation: The findings in this report indicate variations in health risk behaviors and use of preventive health screenings and health services among adults at the state, local, and county levels. These variations substantiate the continued need for public health surveillance in designing, implementing, monitoring, and evaluating public health policies and health-care use programs to reduce morbidity and mortality from the effect of high-risk health behaviors and subsequent chronic disease outcomes., Public Health Action: Data from BRFSS are essential for monitoring prevalence of high-risk health behaviors, specific diseases, and use of preventive health services; dictating the design, focus, implementation, and evaluation of prevention health programs and strategies; and monitoring progress toward obtaining local, state, and national health objectives. Data from the 2004 BRFSS indicate a continual necessity to initiate and implement health promotion strategies for identifying specific health risk behaviors and practices and for assessing progress toward achieving disease prevention and health promotion objectives at state and local levels throughout the United States.

- Abstract
Background: Between 1999 and 2002, a multistate demonstration project was conducted in long-term care facilities (LTCFs) to encourage implementation of standing orders programs (SOP) as evidence-based vaccine delivery strategies to increase influenza and pneumococcal vaccination coverage in LTCFs., Objective: Examine predictors of increase in influenza and pneumococcal vaccination coverage in LTCFs., Design: Intervention study. Self-administered surveys of LTCFs merged with data from OSCAR (On-line Survey Certification and Reporting System) and immunization coverage was abstracted from residents' medical charts in LTCFs., Setting and Participants: Twenty LTCFs were sampled from 9 intervention and 5 control states in the 2000 to 2001 influenza season for baseline and during the 2001 to 2002 influenza season for postintervention., Intervention: Each state's quality improvement organization (QIO) promoted the use of standing orders for immunizations as well as other strategies to increase immunization coverage among LTCF residents., Main Outcome Measures: Multivariate analysis included Poisson regression to determine independent predictors of at least a 10 percentage-point increase in facility influenza and pneumococcal vaccination coverage., Results: Forty-two (20%) and 59 (28%) of the facilities had at least a 10 percentage-point increase in influenza and pneumococcal immunizations, respectively. In the multivariate analysis, predictors associated with increase in influenza vaccination coverage included adoption of requirement in written immunization protocol to document refusals, less-demanding consent requirements, lower baseline influenza coverage, and small facility size. Factors associated with increase in pneumococcal vaccination coverage included adoption of recording pneumococcal immunizations in a consistent place, affiliation with a multifacility chain, and provision of resource materials., Conclusions: To improve the health of LTCF residents, strategies should be considered that increase immunization coverage, including written protocol for immunizations and documentation of refusals, documenting vaccination status in a consistent place in medical records, and minimal consent requirements for vaccinations.

- Abstract
Background and Purpose: The National Institutes of Health (NIH) estimates that stroke costs now exceed 45 billion dollars per year. Stroke is the third leading cause of death and one of the leading causes of adult disability in North America, Europe, and Asia. A number of well-designed randomized stroke trials and case series have now been reported in the literature to evaluate the safety and efficacy of thrombolytic therapy for the treatment of acute ischemic stroke. These stroke trials have included intravenous studies, intra-arterial studies, and combinations of both, as well as use of mechanical devices for removal of thromboemboli and of neuroprotectant drugs, alone or in combination with thrombolytic therapy. At this time, the only therapy demonstrated to improve outcomes from an acute stroke is thrombolysis of the clot responsible for the ischemic event. There is room for improvement in stroke lysis studies. Divergent criteria, with disparate reporting standards and definitions, have made direct comparisons between stroke trials difficult to compare and contrast in terms of overall patient outcomes and efficacy of treatment. There is a need for more uniform definitions of multiple variables such as collateral flow, degree of recanalization, assessment of perfusion, and infarct size. In addition, there are multiple unanswered questions that require further investigation, in particular, questions as to which patients are best treated with thrombolysis. One of the most important predictors of clinical success is time to treatment, with early treatment of <3 hours for intravenous tissue plasminogen activator and <6 hours for intra-arterial thrombolysis demonstrating significant improvement in terms of 90-day clinical outcome and reduced cerebral hemorrhage. It is possible that improved imaging that identifies the ischemic penumbra and distinguishes it from irreversibly infarcted tissue will more accurately select patients for therapy than duration of symptoms. There are additional problems in the assessment of patients eligible for thrombolysis. These include being able to predict whether a particular site of occlusion can be successfully revascularized, predict an individual patient's prognosis and outcome after revascularization, and in particular, to predict the development of intracerebral hemorrhage, with and without clinical deterioration. It is not clear to assume that achieving immediate flow restoration due to thrombolytic therapy implies clinical success and improved outcome. There is no simple correlation between recanalization and observed clinical benefit in all ischemic stroke patients, because other interactive variables, such as collateral circulation, the ischemic penumbra, lesion location and extent, time to treatment, and hemorrhagic conversion, are all interrelated to outcome., Methods: This article was written under the auspices of the Technology Assessment Committees for both the American Society of Interventional and Therapeutic Neuroradiology and the Society of Interventional Radiology. The purpose of this document is to provide guidance for the ongoing study design of trials of intra-arterial cerebral thrombolysis in acute ischemic stroke. It serves as a background for the intra-arterial thrombolytic trials in North America and Europe, discusses limitations of thrombolytic therapy, defines predictors for success, and offers the rationale for the different considerations that might be important during the design of a clinical trial for intra-arterial thrombolysis in acute stroke. Included in this guidance document are suggestions for uniform reporting standards for such trials. These definitions and standards are mainly intended for research trials; however, they should also be helpful in clinical practice and applicable to all publications. This article serves to standardize reporting terminology and includes pretreatment assessment, neurologic evaluation with the NIH Stroke Scale score, imaging evaluation, occlusion sites, perfusion grades, follow-up imaging studies, and neurologic assessments. Moreover, previously used and established definitions for patient selection, outcome assessment, and data analysis are provided, with some possible variations on specific end points. This document is therefore targeted to help an investigator to critically review the scales and scores used previously in stroke trials. This article also seeks to standardize patient selection for treatment based on neurologic condition at presentation, baseline imaging studies, and utilization of standardized inclusion/exclusion criteria. It defines outcomes from therapy in phase I, II, and III studies. Statistical approaches are presented for analyzing outcomes from prospective, randomized trials with both primary and secondary variable analysis. A discussion on techniques for angiography, intra-arterial thrombolysis, anticoagulation, adjuvant therapy, and patient management after therapy is given, as well as recommendations for posttreatment evaluation, duration of follow-up, and reporting of disability outcomes. Imaging assessment before and after treatment is given. In the past, noncontrast CT brain scans were used as the initial screening examination of choice to exclude cerebral hemorrhage. However, it is now possible to quantify the volume of early infarct by using contiguous, discrete (nonhelical) images of 5 mm. In addition, CT angiography by helical scanning and 100 mL of intravenous contrast agent can be used expeditiously to obtain excellent vascular anatomy, define the occlusion site, obtain 2D and 3D reformatted vascular images, grade collateral blood flow, and perform tissue-perfusion studies to define transit times of a contrast bolus through specific tissue beds and regions of interest in the brain. Dynamic CT perfusion scans to assess the whole dynamics of a contrast agent transit curve can now be routinely obtained at many hospitals involved in these studies. The rationale, current status of this technology, and potential use in future clinical trials are given. Many hospitals are also performing MR brain studies at baseline in addition to, or instead of, CT scans. MRI has a high sensitivity and specificity for the diagnosis of ischemic stroke in the first several hours from symptom onset, identifies arterial occlusions, and characterizes ischemic pathology noninvasively. Case series have demonstrated and characterized the early detection of intraparenchymal hemorrhage and subarachnoid hemorrhage by MRI. Echo planar images, used for diffusion MRI and, in particular, perfusion MRI are inherently sensitive for the susceptibility changes caused by intraparenchymal blood products. Consequently, MRI has replaced CT to rule out acute hemorrhage in some centers. The rationale and the potential uses of MR scanning are provided. In addition to established criteria, technology is continuously evolving, and imaging techniques have been introduced that offer new insights into the pathophysiology of acute ischemic stroke. For example, a better patient stratification might be possible if CT and/or MRI brain scans are used not only as exclusion criteria but also to provide individual inclusion and exclusion criteria based on tissue physiology. Imaging techniques might also be used as a surrogate outcome measure in future thrombolytic trials. The context of a controlled study is the best environment to validate emerging imaging and treatment techniques. The final section details reporting standards for complications and adverse outcomes; defines serious adverse events, adverse events, and unanticipated adverse events; and describes severity of complications and their relation to treatment groups. Recommendations are made regarding comparing treatment groups, randomization and blinding, intention-to-treat analysis, quality-of-life analysis, and efficacy analysis. This document concludes with an analysis of general costs associated with therapy, a discussion regarding entry criteria, outcome measures, and the variability of assessment of the different stroke scales currently used in the literature is also featured., Conclusions: In summary, this article serves to provide a more uniform set of criteria for clinical trials and reporting outcomes used in designing stroke trials involving intra-arterial thrombolytic agents, either alone or in combination with other therapies. It is anticipated that by having a more uniform set of reporting standards, more meaningful analysis of the data and the literature will be able to be achieved.

- Abstract
Problem/condition: The reported prevalence of anencephaly and spina bifida in the United States has steadily declined since the late 1960s. During this time, the ability to diagnose these defects prenatally has progressed rapidly. Many U.S. birth defects surveillance systems ascertain defects only among live-born infants or among infants and fetuses beyond a certain gestational age, thus excluding defects among pregnancies prenatally diagnosed as being affected by a neural tube defect (NTD) and electively terminated before the gestational age limit. The impact of prenatal diagnosis and subsequent pregnancy termination on the reported prevalence of anencephaly and spina bifida in the United States has not been well established. However, assessment of this impact is crucial to the use of surveillance data to monitor trends in the occurrence of NTDs and the effectiveness of interventions for these defects (e.g., increased consumption of folic acid)., Reporting Period: This report presents data from birth defects surveillance systems in six states over different time periods: Arkansas, 1985-1989; California, 1989-1991; Georgia, 1990-1991; Hawaii, 1988-1994; Iowa, 1985-1990; and South Carolina, 1992-1993., Description of Systems: Population-based data about a) live-born and stillborn infants with anencephaly and spina bifida and b) pregnancies electively terminated after prenatal diagnosis of these defects were analyzed from the Arkansas Reproductive Health Monitoring System; the California Birth Defects Monitoring Program; CDC's Metropolitan Atlanta Congenital Defects Program; the Iowa Birth Defects Registry, the University of Iowa, and the Iowa Department of Public Health; and the Greenwood Genetic Center in South Carolina. Data also were analyzed from the Hawaii Birth Defects Monitoring Program, which includes data for some women who were not residents of the state. The systems differed in the size and racial/ethnic composition of the populations studied, the surveillance methods used, the completeness of ascertainment, and the availability and utilization of prenatal testing and pregnancy termination., Results and Interpretation: Among all pregnancies ascertained in which the infant or fetus had anencephaly or spina bifida, the percentages that were electively terminated ranged from 9% in Arkansas to 42% in Atlanta and Hawaii, with a corresponding increase in the adjusted prevalence of these defects compared with the prevalence at birth. In each system, pregnancies associated with anencephaly were terminated more frequently than were those associated with spina bifida. These data indicate that the impact of prenatal diagnosis and subsequent pregnancy termination on the prevalence at birth of anencephaly and spina bifida differs among geographic areas and populations. Comprehensive surveillance for these defects requires inclusion of pregnancies that are prenatally diagnosed and then terminated., Actions Taken: CDC will use these data to promote the inclusion of prenatally diagnosed and terminated pregnancies in estimates of the prevalence of anencephaly and spina bifida generated by birth defects surveillance programs in the United States. Including such pregnancies is crucial to the ability of these programs to monitor trends accurately and to establish the effectiveness of interventions, including the use of folic acid, for these defects.

- Abstract
This article presents an overview of the credibility of DNA profiling in criminal trials. DNA profiling does not provide absolute identification but has to be considered as a component of evidence. Apart from being used to help determine guilt it can be used to exonerate suspects.
