Deaths of parents and grandparent caregivers threaten child well-being owing to losses of care, financial support, safety and family stability, but are relatively unrecognized as a public health crisis. Here we used cause-specific vital statistics death registrations in a modeling approach to estimate the full magnitude of orphanhood incidence and prevalence among US children aged 0-17 years between 2000 and 2021 by cause, child age, race and ethnicity, sex of deceased parent and state, and also accounted for grandparent caregiver loss using population survey data. In 2021, we estimate that 2.91 million children (4.2% of children) had in their lifetime experienced prevalent orphanhood and caregiver death combined, with incidence increasing by 49.5% and prevalence by 7.9% since 2000. Populations disproportionately affected by orphanhood included 5.2% of all adolescents; 6.4% and 4.7%, respectively, of non-Hispanic American Indian or Alaska Native, and non-Hispanic Black children; and children in southern and eastern states. In 2021, drug overdose was the leading cause of orphanhood among non-Hispanic white children, but not among minoritized subgroups. Effective policies and programs to support nearly three million bereaved children are needed to reduce the acute and long-term negative effects of orphanhood.

IMPORTANCE: Given the high number of opioid overdose deaths in the US and the complex epidemiology of opioid use disorder (OUD), systems models can serve as a tool to identify opportunities for public health interventions. OBJECTIVE: To estimate the projected 3-year association between public health interventions and opioid overdose-related outcomes among persons with OUD. DESIGN, SETTING, AND PARTICIPANTS: This decision analytical model used a simulation model of the estimated US population aged 12 years and older with OUD that was developed and analyzed between January 2019 and December 2023. The model was parameterized and calibrated using 2019 to 2020 data and used to estimate the relative change in outcomes associated with simulated public health interventions implemented between 2021 and 2023. MAIN OUTCOMES AND MEASURES: Projected OUD and medications for OUD (MOUD) prevalence in 2023 and number of nonfatal and fatal opioid-involved overdoses among persons with OUD between 2021 and 2023. RESULTS: In a baseline scenario assuming parameters calibrated using 2019 to 2020 data remained constant, the model projected more than 16 million persons with OUD not receiving MOUD treatment and nearly 1.7 million persons receiving MOUD treatment in 2023. Additionally, the model projected over 5 million nonfatal and over 145 000 fatal opioid-involved overdoses among persons with OUD between 2021 and 2023. When simulating combinations of interventions that involved reducing overdose rates by 50%, the model projected decreases of up to 35.2% in nonfatal and 36.6% in fatal opioid-involved overdoses among persons with OUD. Interventions specific to persons with OUD not currently receiving MOUD treatment demonstrated the greatest reduction in numbers of nonfatal and fatal overdoses. Combinations of interventions that increased MOUD initiation and decreased OUD recurrence were projected to reduce OUD prevalence by up to 23.4%, increase MOUD prevalence by up to 137.1%, and reduce nonfatal and fatal opioid-involved overdoses among persons with OUD by 6.7% and 3.5%, respectively. CONCLUSIONS AND RELEVANCE: In this decision analytical model study of persons with OUD, findings suggested that expansion of evidence-based interventions that directly reduce the risk of overdose fatality among persons with OUD, such as through harm reduction efforts, could engender the highest reductions in fatal overdoses in the short-term. Interventions aimed at increasing MOUD initiation and retention of persons in treatment projected considerable improvement in MOUD and OUD prevalence but could require a longer time horizon for substantial reductions in opioid-involved overdoses.

We thank Drs Miller, Loewen, Szeinuk, and Noonan for their comments and insights regarding the burden of asbestos-related disease (ARD) among current and former Libby residents, as well as on our publication.1 We agree with Dr Loewen’s observation that local physicians may not have noted ARD in this cohort of screening participants. This could have resulted in under-ascertainment of nonmalignant, ARD mortality. (Note that we reported results for asbestosis, a nonmalignant disease defined as interstitial pneumonitis and fibrosis caused by inhalation of asbestos.2) Still, the asbestosis SMRs we reported ranged from 82 (among workers categorized as “other asbestos occupation”) to 558 (among household contacts) in comparison with a national reference population. These SMRs clearly indicate a striking excess of nonmalignant ARD in the screening cohort.

INTRODUCTION: Stigma associated with substance use and addiction is a major barrier to overdose prevention. Although stigma reduction is a key goal of federal strategies to prevent overdose, there is limited data to assess progress made in reducing use of stigmatizing language about addiction. METHODS: Using language guidelines published by the federal National Institute on Drug Abuse (NIDA), we examined trends in use of stigmatizing terms about addiction across four popular public communication modalities: news articles, blogs, Twitter, and Reddit. We calculate percent changes in the rates of articles/posts using stigmatizing terms over a five-year period (2017-2021) by fitting a linear trendline and assess statistically significant trends using the Mann-Kendall test. RESULTS: The rate of articles containing stigmatizing language decreased over the past five years for news articles (-68.2 %, p < 0.001) and blogs (-33.6 %, p < 0.001). Among social media platforms, the rate of posts using stigmatizing language increased (Twitter [43.5 %, p = 0.01]) or remained stable (Reddit [3.1 %, p = 0.29]). In absolute terms, news articles had the highest rate of articles containing stigmatizing terms over the five-year period (324.9 articles per million) compared to 132.3, 18.3, and 138.6 posts per million for blogs, Twitter, and Reddit, respectively. CONCLUSIONS: Use of stigmatizing language about addiction appears to have decreased across more traditional, longer-format communication modalities such as news articles. Additional work is needed to reduce use of stigmatizing language on social media.

The Martinsburg Initiative (TMI) is a community-based model developed in Martinsburg, West Virginia, that implements a comprehensive approach to adverse childhood experiences and substance use prevention and mitigation by leveraging partnerships in public health and health care, public safety, and education. TMI receives coordinated federal funding and technical assistance from the Centers for Disease Control and Prevention, the Washington-Baltimore High Intensity Drug Trafficking Agency, and the National Association of County and City Health Officials to integrate evidence-based and promising strategies. It advances such strategies by translating them for implementation within the community, evaluating the reach and potential impact of the model, and by engaging key stakeholders. Preliminary results describing program reach and short-term outcomes collected for a subset of the interventions during implementation are presented. The model uses touchpoints across multiple community sectors in the city of Martinsburg to break the cycle of trauma and substance use across the life span.

CONTEXT: Public health and public safety collaborations can strengthen and improve efforts to address the worsening drug overdose crisis. PROGRAM: The Overdose Response Strategy is addressing this need through a national public health and public safety program designed to foster the cross-sector sharing of timely data, pertinent intelligence, and evidence-based and innovative strategies to prevent and respond to drug overdose. IMPLEMENTATION: Since 2015, the Overdose Response Strategy has been implemented by state-based public health and public safety teams who work together to prevent and respond to drug overdoses within and across sectors, states, and territories. The public health and public safety teams share data systems to inform rapid and effective community overdose prevention efforts; support immediate, evidence-based response efforts that can directly reduce overdose deaths; design and use promising strategies at the intersection of public health and public safety; and use effective and efficient primary prevention strategies that can reduce substance use and overdose long term. Implementation of the Overdose Response Strategy aligns with the US Centers for Disease Control and Prevention's Strategic Partnering Framework. EVALUATION: The evaluation of the Overdose Response Strategy, which is currently underway, is based on 2 evaluation approaches: Collective Impact and Organizational Network Analysis. These approaches provide a way to look at the strength of the relationship between public health and public safety and the way the relationship is leveraged to advance program goals and objectives. DISCUSSION: The Overdose Response Strategy serves as a strategic partnership model that can potentially be applied to other issues, such as gun violence, that may benefit from public health and public safety collaboration.

Background Rheumatic heart disease (RHD) is a severe, chronic complication of acute rheumatic fever, triggered by group A streptococcal pharyngitis. Centralized patient registries are recommended for RHD prevention and control, but none exists in American Samoa. Using existing RHD tracking systems, we estimated RHD period prevalence and the proportion of people with RHD documented in the electronic health record. Methods and Results RHD cases were identified from a centralized electronic health record system, which retrieved clinical encounters with RHD International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes, clinical problem lists referencing RHD, and antibiotic prophylaxis administration records; 3 RHD patient tracking spreadsheets; and an all-cause mortality database. RHD cases had ≥1 clinical encounter with RHD ICD-10-CM codes, a diagnostic echocardiogram, or RHD as a cause of death, or were included in RHD patient tracking spreadsheets. Period prevalence per 1000 population among children aged <18 years and adults aged ≥18 years from 2016 to 2018 and the proportion of people with RHD with ≥1 clinical encounter with an RHD ICD-10-CM code were estimated. From 2016 to 2018, RHD was documented in 327 people (57.2%: children aged <18 years). Overall RHD period prevalence was 6.3 cases per 1000 and varied by age (10.0 pediatric cases and 4.3 adult cases per 1000). Only 67% of people with RHD had ≥1 clinical encounter with an RHD ICD-10-CM code. Conclusions RHD remains a serious public health problem in American Samoa, and the existing electronic health record does not include all cases. A centralized patient registry could improve tracking people with RHD to ensure they receive necessary care.

BACKGROUND: Every year thousands of wildland firefighters (WFFs) work to suppress wildfires to protect public safety, health, and property. Although much effort has been put toward mitigating air pollutant exposures for the public and WFFs, the current burden in this worker population is unclear as are the most effective exposure reduction strategies. OBJECTIVE: Quantify fireline carbon monoxide (CO) exposures in WFFs and identify predictors of exposures. METHODS: We collected 1-min breathing zone CO measurements on 246 WFFs assigned to fires between 2015 and 2017. We used generalized estimating equations to evaluate predictors of CO exposure. RESULTS: Approximately 5% of WFFs had fireline CO exposure means exceeding the National Wildfire Coordinating Group's occupational exposure limit of 16 ppm. Relative to operational breaks, direct suppression-related job tasks were associated with 56% (95% CI: 47%, 65%) higher geometric mean CO concentrations, adjusted for incident type, crew type, and fire location. WFF perception of smoke exposure was a strong predictor of measured CO exposure. SIGNIFICANCE: Specific job tasks related to direct suppression and WFF perceptions of smoke exposure are potential opportunities for targeted interventions aimed at minimizing exposure to smoke.

The coronavirus disease 2019 (COVID-19) global response underscores the need for a multidisciplinary approach that integrates and coordinates various public health systems-surveillance, laboratory, and health-care systems/networks, among others-as part of a larger emergency response system. Multidisciplinary public health rapid response teams (RRTs) are one mechanism used within a larger COVID-19 outbreak response strategy. As COVID-19 RRTs are deployed, countries are facing operational challenges in optimizing their RRT's impact, while ensuring the safety of their RRT responders. From March to May 2020, United States Centers for Disease Control and Prevention received requests from 12 countries for technical assistance related to COVID-19 RRTs and emergency operations support. Challenges included: (1) an insufficient number of RRT responders available for COVID-19 deployments; (2) limited capacity to monitor RRT responders' health, safety, and resiliency; (3) difficulty converting critical in-person RRT operational processes to remote information technology platforms; and (4) stigmatization of RRT responders hindering COVID-19 interventions. Although geographically and socioeconomically diverse, these 12 countries experienced similar RRT operational challenges, indicating potential applicability to other countries. As the response has highlighted the critical need for immediate and effective implementation measures, addressing these challenges is essential to ensuring an impactful and sustainable COVID-19 response strategy globally.

BACKGROUND: Emerging evidence suggests the composition of local illicit drug markets varies over time and the availability and relative lethality of illicit drugs may contribute to temporal trends in overdose mortality. Law enforcement drug seizures represent a unique opportunity to sample the makeup of local drug markets. Prior research has associated shifts in the types of drugs seized and trends in unintentional drug overdose mortality. The present report builds on this work by demonstrating a novel methodology, the Street-Drug Lethality Index, which may serve as a low-lag predictor of unintentional overdose deaths. METHODS: Data included administrative records of law enforcement drug seizures and unintentional drug overdose deaths in Ohio from 2009 -to- 2018. Death records and lab results from drug seizures occurring during the calendar year 2017 were transformed via the described procedure to create lethality indices for individual drugs. These indices were then summed annually to create the independent variable for a linear regression model predicting unintentional overdose deaths for all years during the study period. RESULTS: The regression model explained 93 % of the year-to-year variance in unintentional overdose fatalities (slope = 0.009480; CI = 0.007369 to 0.011590; t(10) = 10.355942; P = 0.000007; Y = 11.808982 + 0.009480X, r(2) = 0.931). CONCLUSION: These findings contribute to a growing body of evidence that changes in the composition of the drug supply may predict trends in unintentional overdose mortality. The proposed methodology might inform future overdose prevention and response efforts as well as research.

The current overdose epidemic in the US that began in the late 1990s continues unabated. Since 2013, deaths involving synthetic opioids surged substantially, largely due to the rapid proliferation of illicitly manufactured fentanyl and fentanyl analogs (eg, acetylfentanyl, carfentanil).1,2 More recently, overdose deaths involving stimulants, such as methamphetamine and cocaine, have increased with and without opioid co-involvement.3,4 As illicitly manufactured fentanyl became more ubiquitous, drug overdose death rates increased in all age groups, among both sexes, across most races and ethnicities, within all urbanization levels, and in the majority of US states.1

BACKGROUND: Rates of fatal overdose (OD) from synthetic opioids rose nearly 60 % from 2016 to 2018. 911 Good Samaritan Laws (GSLs) are an evidenced-based strategy for preventing OD fatality. This study describes patrol officers' knowledge of their state's GSL, experience with OD response, and their perspectives on strategies to prevent and respond to opioid OD. METHODS: An electronic survey assessed officers' knowledge of state GSLs and experiences responding to OD. Descriptive statistics and hierarchical linear modeling were generated to examine differences in knowledge, preparedness, and endorsement of OD response efforts by experience with OD response. RESULTS: 2,829 officers responded to the survey. Among those who had responded to an OD call in the past six months (n = 1,946), 37 % reported administering naloxone on scene and 36 % reported making an arrest. Most (91 %) correctly reported whether their state had a GSL in effect. Only 26 % correctly reported whether that law provides limited immunity from arrest. Fifteen percent of officers who had responded to an OD work in departments that do not carry naloxone. Compared with officers who had not responded to any OD calls, those who reported responding OD calls at least monthly and at least weekly, were significantly less likely to endorse OD response efforts. CONCLUSION: Officers who respond to OD calls are generally receiving training and naloxone supplies to respond, but knowledge gaps and additional training needs persist. Additional training and strategies to relieve compassion fatigue among those who have more experience with OD response efforts may be indicated.

BACKGROUND: Expanding access to treatment and recovery services is key to reducing substance use-related harms. Fundamental to expanding such services is better understanding the populations identifying themselves as in recovery. This study uses nationally representative data to estimate prevalence and correlates of recovery in the U.S. METHODS: Data are from the 43,026 adults (aged 18 or older) participating in the 2018 National Survey on Drug Use and Health. Based on self-reported data, we estimate prevalence of ever having a substance use problem, the percentage in recovery among those with a substance use problem, and a multivariable logistic regression model to explore associations of recovery status with demographic characteristics and lifetime mental health problems. Among adults reporting a substance use problem, we compare prevalence of substance use by recovery status, followed by a multivariable model examining associations between each substance used and being in recovery. RESULTS: More than 1 in 10 adults (27.5 million) in the U.S. reported ever having a substance use problem, and, among those with a problem, nearly 75 % (20.5 million) reported being in recovery. Reporting lower prevalence of using substances in the past year and having received treatment for their substance use problem were associated with being in recovery. Ever having a mental health problem was highly prevalent among those reporting a substance use problem. CONCLUSIONS: The provision and expansion of substance use treatment services continues to be important to reduce harms related to substance use, especially for those with both substance use and mental health disorders.

In 2016, 63 632 persons died of a drug overdose in the United States; 66.4% (42 249) involved an opioid.1 Opioid-involved deaths include prescription opioid analgesics (e.g., morphine, oxycodone), illicit opioids (e.g., heroin, illicitly manufactured fentanyl [IMF]), or both. Although prescription and illicit opioid overdoses are closely entwined,2 it is important to differentiate the deaths to craft appropriate prevention and response efforts. Unfortunately, disentangling these deaths is challenging because multiple drugs are often involved. Additionally, death certificate data do not specify whether the drugs were pharmaceutically manufactured and prescribed by a health care provider, pharmaceutically manufactured but not prescribed to the person (i.e., diverted prescriptions), or illicitly manufactured.

Drug overdose accounted for 52 404 deaths in the United States in 2015,1 which are more deaths than for AIDS at its peak in 1995. Provisional data from the US Centers for Disease Control and Prevention (CDC) indicate drug overdose deaths increased again from 2015 to 2016 by more than 20% (from 52 898 deaths in the year ending in January 2016 to 64 070 deaths in the year ending in January 2017).2 Increases are greatest forover-doses related to the category including illicitly manufactured fentanyl (ie, synthetic opioids excluding methadone), which more than doubled, accounting for more than 20 000 overdose deaths in 2016 vs less than 10 000 deaths in 2015. This difference is enough to account for nearly all the increase in drug overdose deaths from 2015 to 2016.2 | Since 2010, overdose deaths involving predominantly illicit opioids (heroin, synthetic nonmethadone opioids, or both) have increased by more than 200% (Figure). Why have overdose deaths related to illicit opioids increased so substantially? Data from the National Survey on Drug Use and Health reveal moderate increases in people reporting past-year heroin use from 2010 to 2015 (Figure). Increasing numbers of individuals who use heroin are younger, might be less experienced, and might use heroin in riskier ways that are difficult to measure (eg, using it alone, using more heroin, using it more often, or combining drugs).

CDC has updated the interim guidance for U.S. health care providers caring for pregnant women with possible Zika virus exposure in response to 1) declining prevalence of Zika virus disease in the World Health Organization's Region of the Americas (Americas) and 2) emerging evidence indicating prolonged detection of Zika virus immunoglobulin M (IgM) antibodies. Zika virus cases were first reported in the Americas during 2015-2016; however, the incidence of Zika virus disease has since declined. As the prevalence of Zika virus disease declines, the likelihood of false-positive test results increases. In addition, emerging epidemiologic and laboratory data indicate that, as is the case with other flaviviruses, Zika virus IgM antibodies can persist beyond 12 weeks after infection. Therefore, IgM test results cannot always reliably distinguish between an infection that occurred during the current pregnancy and one that occurred before the current pregnancy, particularly for women with possible Zika virus exposure before the current pregnancy. These limitations should be considered when counseling pregnant women about the risks and benefits of testing for Zika virus infection during pregnancy. This updated guidance emphasizes a shared decision-making model for testing and screening pregnant women, one in which patients and providers work together to make decisions about testing and care plans based on patient preferences and values, clinical judgment, and a balanced assessment of risks and expected outcomes.

SYNOPSIS Over the last two decades, experts have reported a rising number of deaths caused by chronic kidney disease (CKD) along the Pacific coast of Central America, from southern Mexico to Costa Rica. However, this specific disease is not associated with traditional causes of CKD, such as aging, diabetes, or hypertension. Rather, this disease is a chronic interstitial nephritis termed chronic kidney disease of nontraditional etiology (CKDnT). According to the Pan American Health Organization (PAHO) mortality database, there are elevated rates of deaths related to kidney disease in many of these countries, with the highest rates being reported in El Salvador and Nicaragua. This condition has been identified in certain agricultural communities, predominantly among male farmworkers. Since CKD surveillance systems in Central America are under development or nonexistent, experts and governmental bodies have recommended creating standardized case definitions for surveillance purposes to monitor and characterize this epidemiological situation. A group of experts from Central American ministries of health, the U.S. Centers for Disease Control and Prevention (CDC), and PAHO held a workshop in Guatemala to discuss CKDnT epidemiologic case definitions. In this paper, we propose that CKD in general be identified by the standard definition internationally accepted and that a suspect case of CKDnT be defined as a person age < 60 years with CKD, without type 1 diabetes mellitus, hypertensive diseases, and other well-known causes of CKD. A probable case of CKDnT is defined as a suspect case with the same findings confirmed three or more months later.

To address the opioid overdose epidemic in the United States, states have implemented policies to reduce inappropriate opioid prescribing. These policies could affect the coincident heroin overdose epidemic by either driving the substitution of heroin for opioids or reducing simultaneous use of both substances. We used IMS Health's National Prescription Audit and government mortality data to examine the effect of these policies on opioid prescribing and on prescription opioid and heroin overdose death rates in the United States during 2006-13. The analysis revealed that combined implementation of mandated provider review of state-run prescription drug monitoring program data and pain clinic laws reduced opioid amounts prescribed by 8 percent and prescription opioid overdose death rates by 12 percent. We also observed relatively large but statistically insignificant reductions in heroin overdose death rates after implementation of these policies. This combination of policies was effective, but broader approaches to address these coincident epidemics are needed.

Despite the mandatory nature of Lyme disease (LD) reporting in New York State (NYS), it is believed that only a fraction of the LD cases diagnosed annually are reported to public health authorities. Lack of complete LD case reporting generally stems from (i) lack of report of provider-diagnosed cases where supportive laboratory testing is not ordered or results are negative (i.e. provider underreporting) and (ii) incomplete case information (clinical laboratory reporting only with no accompanying clinical information) such that cases are considered 'suspect' and not included in national and statewide case counts (i.e. case misclassification). In an attempt to better understand LD underreporting in NYS, a two-part study was conducted in 2011 using surveillance data from three counties. Case misclassification was assessed by obtaining medical records on suspect cases and reclassifying according to the surveillance case definition. To assess provider underreporting, lists of patients for whom ICD-9-CM code 088.81 (LD) had been used were reported to NYS Department of Health (NYSDOH). These lists were matched to the NYSDOH case reporting system, and medical records were requested on patients not previously reported; cases were then classified according to the case definition. When including both provider underreporting and case misclassification, approximately 20% (range 18.4-24.6%) more LD cases were identified in the three-county study area than were originally reported through standard surveillance. The additional cases represent a minimum percentage of unreported cases; the true percentage of unreported cases is likely higher. Unreported cases were more likely to have a history of erythema migrans (EM) rash and were more likely to be young paediatric cases. Results of the study support the assertion that LD cases are underreported in NYS. Initiatives to increase reporting should highlight the importance of reporting clinically diagnosed EM and be targeted to those providers most likely to diagnose LD, specifically providers treating paediatric patients.

Injury and violence prevention strategies have greater potential for impact when they are based on scientific evidence. Systematic reviews of the scientific evidence can contribute key information about which policies and programs might have the greatest impact when implemented. However, systematic reviews have limitations, such as lack of implementation guidance and contextual information, that can limit the application of knowledge. "Technical packages," developed by knowledge brokers such as the federal government, nonprofit agencies, and academic institutions, have the potential to be an efficient mechanism for making information from systematic reviews actionable. Technical packages provide information about specific evidence-based prevention strategies, along with the estimated costs and impacts, and include accompanying implementation and evaluation guidance to facilitate adoption, implementation, and performance measurement. We describe how systematic reviews can inform the development of technical packages for practitioners, provide examples of technical packages in injury and violence prevention, and explain how enhancing review methods and reporting could facilitate the use and applicability of scientific evidence.

The current investigation examined the interactive effect of dysfunctional dating attitudes and religiosity on substance use in a large sample of youth (N = 1,357) from the YouthStyles survey. Based on past research, we explored the possibility that religiosity buffered the association between dysfunctional dating attitudes and substance use. Because age was significantly associated with all study variables, we included age in our analyses. In support of our hypothesis we found an attitude by religiosity by age interaction among youth with moderate levels of dysfunctional dating attitudes. Among these youth, the buffering effect of religiosity increased with age. For youth with low and high dysfunctional dating attitudes, religiosity did not buffer the association. The results of this study are in line with past work that suggests that the association between relationship characteristics and substance use is complex. It also identifies religiosity as a protective factor for the effect of dating attitudes on substance use but suggests that these effects may be the most important for youth with moderate levels of dysfunctional dating attitudes.

Older adult falls remain a significant public health problem amenable to preventive interventions (CDC, 2009; CDC, 2011). Despite the progress made in identifying risk factors, developing efficacious health-related interventions, and promoting evidence-based programs in the community, much work remains before these strategies are broadly available and effectively used to reduce fall-related injuries (Noonan, Sleet, Stevens, 2011). Newton and Scott-Findlay (2007) point out that the translation of basic scientific knowledge into clinical studies, and from clinical studies to improvements in health services and public health practices, remain major obstacles to widespread adoption. | Donaldson and Finch (2013) showed the feasibility of applying implementation science to sports injury prevention and Li et al (2008) demonstrated how an exercise and balance program (Tai Chi) can successfully be translated into a community program. As important, Li and colleagues maintained program fidelity and adherence to their intervention, at least over the short term, to prevent older adult falls. Manson et al (2013) showed positive results taking a Tai Chi program to low-income older adults, concluding that “non-(Tai chi) culturally related ethnic groups did not experience a barrier to participation in an older low-socioeconomic population sample” (p270). However, the sample consisted of only 56 participants who were recruited into a 16-week program and no attempt was made to translate the findings to the wider multi-ethnic community through the use of existing stakeholders.

This article presents what the authors consider to be among the top 20 practice innovations since the inception of the National Center for Injury Prevention and Control in 1992. The innovations embody various characteristics of successful public health programs and have contributed to declines in violence, motor vehicle, residential fire, and other injury rates over the past 20 years. Taken together, these innovations have reduced the burden of violence and injury and have influenced current practice and practitioners in the United States and worldwide.

The establishment of the National Center for Injury Prevention and Control (NCIPC or Injury Center) in 1992 as part of the Centers for Disease Control and Prevention (CDC) firmly established the Injury Center as the lead federal agency for non-occupational injury prevention and control (Sleet et al., 2012). Since then, it has provided leadership and a strong scientific base for intramural and extramural-investigator funded injury research. The Injury Center's scientific mission encompasses efforts from primary prevention to treatment and rehabilitation. Early CDC efforts were primarily focused on describing the extent of the problem, identifying risk and protective factors that affect the extent of violence and injury in our society, and gaining visibility for violence and injury as a major public health problem. Efforts such as the development of injury-based surveillance systems provided population-based surveillance data regarding the extent and distribution of fatal and non-fatal injuries, helped to identify demographic characteristics for those who were most at risk, and identified risk and protective factors that influence that risk. Celebrating the Injury Center's 20th anniversary presents an opportunity not only to reflect on past accomplishments but also to look ahead at what still needs to be done.

BACKGROUND: Falls are a leading cause of unintentional injury among adults age 65 years and older. Loose, unsecured rugs and damaged carpets with curled edges, are recognized environmental hazards that may contribute to falls. To characterize nonfatal, unintentional fall-related injuries associated with rugs and carpets in adults aged 65 years and older. METHODS: We conducted a retrospective analysis of surveillance data of injuries treated in hospital emergency departments (EDs) during 2001-2008. We used the National Electronic Injury Surveillance System-All Injury Program, which collects data from a nationally representative stratified probability sample of 66 U.S. hospital EDs. Sample weights were used to make national estimates. RESULTS: Annually, an estimated 37,991 adults age 65 years or older were treated in U.S. EDs for falls associated with carpets (54.2%) and rugs (45.8%). Most falls (72.8%) occurred at home. Women represented 80.2% of fall injuries. The most common location for fall injuries in the home was the bathroom (35.7%). Frequent fall injuries occurred at the transition between carpet/rug and non-carpet/rug, on wet carpets or rugs, and while hurrying to the bathroom. CONCLUSION: Fall injuries associated with rugs and carpets are common and may cause potentially severe injuries. Older adults, their caregivers, and emergency and primary care physicians should be aware of the significant risk for fall injuries and of environmental modifications that may reduce that risk.

Various dimensions of parenting have been associated with youth risk behaviors, such as substance use and dating violence. These associations have spawned many prevention strategies that focus on parenting. However, it is unclear which characteristics of parent-youth relationships, and thus, which parent-focused prevention strategies, may be most influential in youth risk behaviors and, thus, which should be targeted in prevention. Using responses from the YouthStyles 2007 survey (N = 1,357), this study identified three youth-reported parent-youth relationship characteristics: communication about risk behaviors, closeness/respect, and rules/monitoring. The authors examined the associations among these characteristics and youths' demographics, attitudes supporting controlling dating relationships, and use of alcohol, marijuana, and tobacco. Results suggested risk behavior communication was more frequently reported by girls and was more frequent among older youth. Closeness/respect and rules/monitoring were more frequent among younger youth. Regressions suggested communication about risk behaviors was not a predictor of attitudes supporting controlling dating relationships but was a significant predictor of substance use, closeness/respect and rules/monitoring predicted substance nonuse and attitudes unsupportive of controlling dating relationships. The findings suggest that parental communication alone may not be sufficient to influence youth risk taking, but that parental monitoring and the establishment of respectful, close relationships with children may be important elements of parent-focused health promotion efforts.

Public health is currently faced with an array of critical challenges and disconnects. Research and evaluation have identified a number of evidence-based strategies for effecting behavior change at individual, group, organizational, and environmental levels, all of which hold promise for leading to substantial reductions in morbidity and mortality, and increased quality of life. Unfortunately, there is huge variability across the public health system in awareness of the value of using evidence to inform decision making, let alone in capacity to locate, assess, compare, select, justify, adapt, implement, and evaluate evidence-based strategies, or to participate in building the evidence base for practice-based innovations. As a result, many communities may not be benefitting from research-tested and practice-based strategies that could help them to meet their public health goals more efficiently and effectively. CDC's Interactive Systems Framework for Dissemination and Implementation (ISF), released in 2008, was designed to help close this gap between research and practice. This commentary identifies the ways in which the ISF framework is useful in addressing the research practice gap; revisits the elements of the framework that have continued to guide research and practice in fruitful ways; and highlights areas that need further development to meet current public health challenges.

In 2006, area physicians reported increases in upper respiratory symptoms in patients living in FEMA-supplied trailers following Hurricanes Katrina and Rita. One potential etiology to explain their symptoms included formaldehyde; however, formaldehyde levels in these occupied trailers were unknown. The objectives of our study were to identify formaldehyde levels in occupied trailers and to determine factors or characteristics of occupied trailers that could affect formaldehyde levels. A disproportionate random sample of 519 FEMA-supplied trailers was identified in Louisiana and Mississippi in November 2007. We collected and tested an air sample from each trailer for formaldehyde levels and administered a survey. Formaldehyde levels among all trailers in this study ranged from 3 parts per billion (ppb) to 590 ppb, with a geometric mean of 77 ppb (95% confidence interval [CI]: 70-85; range: 3-590 ppb). There were statistically significant differences in formaldehyde levels between trailer types (p<0.01). The geometric mean formaldehyde level was 81 ppb (95% CI: 72-92) among travel trailers (n=360), 57 ppb (95% CI: 49-65) among mobile homes (n=57), and 44 ppb (95% CI: 38-53) among park models (n=44). Among travel trailers, formaldehyde levels varied significantly by brand. While formaldehyde levels varied by trailer type, all types tested had some levels ≥100 ppb. (Published 2012.

Unintentional falls among persons aged 65 years and older are an important public health issue, associated with significant mortality and morbidity. About one third of older adults fall annually and, although many fall outcomes are minor, between 10% and 20% cause serious injuries such as traumatic brain injury, contusions, and fractures. Therefore the U.S. Centers for Disease Control and Prevention (CDC) is working to prevent injuries and fatalities due to older adult falls. The public health approach to older adult falls focuses on prevention and is based on scientific rigor. Its steps include defining the problem, identifying causes, developing and testing interventions, and then implementing effective approaches on a large scale. We highlight current CDC activities that map onto each step of the public health model and close by providing future directions for older adult fall prevention, including improved surveillance, support for program implementation, and enhanced partnership building.
