For more than 30 years, the network of Centers for Disease Control and Prevention (CDC)-funded Prevention Research Centers (PRCs) has worked with local communities and partners to implement and evaluate public health interventions and policies for the prevention of disease and promotion of health. The COVID-19 pandemic tested the PRC network's ability to rapidly respond to multiple, simultaneous public health crises. On April 28, 2020, to assess the network's engagement with activities undertaken in response to the early phase of the pandemic, PRC network leadership distributed an online survey to the directors of 34 currently or formerly funded PRCs, asking them to report their PRCs' engagement with predetermined activities across 9 topical areas and provide case studies exemplifying that engagement. We received responses from 24 PRCs, all of which reported engagement with at least 1 of the 9 topical areas (mean, 5). The topical areas with which the greatest number of PRCs reported engagement were support of frontline agencies (21 of 24, 88%) and support of activities related to health care (21 of 24, 88%). The mean number of activities with which PRCs reported engagement was 11. The PRCs provided more than 90 case studies exemplifying their work. The results of the survey indicated that the PRCs mobilized their personnel and resources to support the COVID-19 response in less than 6 weeks. We posit that the speed of this response was due, in part, to the broad and diverse expertise of PRC personnel and long-standing partnerships between PRCs and the communities in which they work.

Background Rifapentine has facilitated treatment shortening of latent tuberculosis infection (LTBI) in combination with isoniazid once weekly for 3 months (3HP) or daily for 1 month (1HP). Objective We determine the optimal rifapentine dose for a 6-week monotherapy regimen (6wP) and predict clinical efficacy. Methods Rifapentine and isoniazid pharmacokinetics were simulated in mice and humans. Mouse lung colony-forming unit data were used to characterize exposure-response relationships of 1HP, 3HP, and 6wP and translated to predict clinical efficacy. Results A 600 mg daily dose for 6wP delivered greater cumulative rifapentine exposure than 1HP or 3HP. The maximum regimen effect (E(max)) was 0.24 day(-1). The regimen potencies, measured as concentration at 50% of E(max) (EC(50)), were estimated as 2.12 mg/L for 3HP, 3.72 mg/L for 1HP, and 4.71 mg/L for 6wP, suggesting that isoniazid contributes little to 1HP efficacy. Clinical translation predicted that 6wP reduces bacterial load at a faster rate than 3HP and a greater extent than 3HP and 1HP. Conclusions 6wP (600 mg daily) is predicted to result in equal or better efficacy than 1HP and 3HP for LTBI treatment without the potential added toxicity of isoniazid. Results from ongoing and future clinical studies will be required to support these findings.

Bats are the second most speciose lineage of mammals with more than 1,300 recognized species. Overall, bats are extremely ecologically and morphologically diverse, making them of interest to a wide variety of biologists. Bats are also known reservoirs for an assortment of zoonotic diseases, including rabies, for which they are commonly tested if identified as sick, behaving abnormally, or in instances where there has been a significant human exposure. In these cases, proper identification of bat species is important to public health experts as it will inform future testing procedures and management practices, as well as broaden our understanding of rabies virus bat variant distributions and disease ecology. Despite the multiple disciplines interested in bats, no key has been developed which includes all species found within the United States. For this reason, a dichotomous key and bat identification guide, designed to differentiate bats to species level, has been developed. This document can be used by people with a variety of backgrounds to morphologically identify bats quickly and accurately using only a scale, a ruler, and attention to detail.

The 30th anniversary of the founding of the Prevention Research Centers (PRC) Network is an appropriate time to reflect on our progress as well as look to the future. Applied prevention research with a focus on understanding health disparities and promoting health equity has never been more important than now. With innovative leadership and a commitment to promoting health for all, the PRC Network has made great strides in developing, testing, and disseminating programs and policies that have had broad and sustained impact. | The PRC Program supports research that identifies unique public health solutions for those who are experiencing health disparities. PRCs conduct community-engaged research that supports the mission of the PRC Program by: | 1 | serving as the hub for conducting high-impact and innovative applied public health prevention research; | 2 | conducting Centers for Disease Control and Prevention (CDC)-supported PRC research focusing on ways to maximize public health resources and reduce healthcare costs, with an emphasis on the leading causes of disease and disability; | 3 | serving as a leader in the field of prevention research for conducting, disseminating, and implementing quality research; | 4 | investing in PRCs and thus supporting their infrastructure and core resources, strengthening centers’ ability to leverage outside resources and expand their reach and impact; | 5 | engaging local communities and serving a resource for public health partners; | 6 | capitalizing on the collaboration and partnership with health departments and other public health partners to translate promising research findings into practical, cost-effective prevention programs relevant to the needs of the communities; and | 7 | collaborating with many partners to train and prepare the public health workforce to assess and evaluate existing health programs or policies.

BACKGROUND: Because residents of the southeastern United States experience disproportionally high rates of cardiovascular disease (CVD), it is important to develop effective lifestyle interventions for this population. METHODS: The primary objective was to develop and evaluate a dietary, physical activity (PA) and weight loss intervention for residents of the southeastern US. The intervention, given in eastern North Carolina, was evaluated in a 2 year prospective cohort study with an embedded randomized controlled trial (RCT) of a weight loss maintenance intervention. The intervention included: Phase I (months 1-6), individually-tailored intervention promoting a Mediterranean-style dietary pattern and increased walking; Phase II (months 7-12), option of a 16-week weight loss intervention for those with BMI ≥ 25 kg/m(2) offered in 2 formats (16 weekly group sessions or 5 group sessions and 10 phone calls) or a lifestyle maintenance intervention; and Phase III (months 13-24), weight loss maintenance RCT for those losing ≥ 8 lb with all other participants receiving a lifestyle maintenance intervention. Change in diet and PA behaviors, CVD risk factors, and weight were assessed at 6, 12, and 24 month follow-up. RESULTS: Baseline characteristics (N = 339) were: 260 (77 %) females, 219 (65 %) African Americans, mean age 56 years, and mean body mass index 36 kg/m(2). In Phase I, among 251 (74 %) that returned for 6 month follow-up, there were substantial improvements in diet score (4.3 units [95 % CI 3.7 to 5.0]), walking (64 min/week [19 to 109]), and systolic blood pressure (-6.4 mmHg [-8.7 to -4.1]) that were generally maintained through 24 month follow-up. In Phase II, 138 (57 group only, 81 group/phone) chose the weight loss intervention and at 12 months, weight change was: -3.1 kg (-4.9 to -1.3) for group (N = 50) and -2.1 kg (-3.2 to -1.0) for group/phone combination (N = 75). In Phase III, 27 participants took part in the RCT. At 24 months, weight loss was -2.1 kg (-4.3 to 0.0) for group (N = 51) and -1.1 kg (-2.7 to 0.4) for combination (N = 72). Outcomes for African American and whites were similar. CONCLUSIONS: The intervention yielded substantial improvement in diet, PA, and blood pressure, but weight loss was modest.

To reduce obesity prevalence, public health practitioners are intervening to change health behaviors as well as the policies, systems, and environments (PSEs) that support healthy behaviors. Although the number of recommended PSE intervention strategies continues to grow, limited guidance is available on how to implement those strategies in practice. This article describes the University of North Carolina at Chapel Hill, Center for Training and Research Translation's (Center TRT's) approach to reviewing, translating, and disseminating practitioner-developed interventions, with the goal of providing more practical guidance on how to implement PSE intervention strategies in real-world practice. As of August 2014, Center TRT had disseminated 30 practice-based PSE interventions. This article provides an overview of Center TRT's process for reviewing, translating, and disseminating practice-based interventions and offers key lessons learned during the nine years that Center TRT has engaged in this work.

INTRODUCTION: Residents of rural communities in the United States are at higher risk for obesity than their urban and suburban counterparts. Policy and environmental-change strategies supporting healthier dietary intake can prevent obesity and promote health equity. Evidence in support of these strategies is based largely on urban and suburban studies; little is known about use of these strategies in rural communities. The purpose of this review was to synthesize available evidence on the adaptation, implementation, and effectiveness of policy and environmental obesity-prevention strategies in rural settings. METHODS: The review was guided by a list of Centers for Disease Control and Prevention Recommended Community Strategies and Measurements to Prevent Obesity in the United States, commonly known as the "COCOMO" strategies. We searched PubMed, Cumulative Index of Nursing and Allied Health Literature, Public Affairs Information Service, and Cochrane databases for articles published from 2002 through 2013 that reported findings from research on nutrition-related policy and environmental strategies in rural communities in the United States and Canada. Two researchers independently abstracted data from each article, and resolved discrepancies by consensus. RESULTS: Of the 663 articles retrieved, 33 met inclusion criteria. The interventions most commonly focused on increasing access to more nutritious foods and beverages or decreasing access to less nutritious options. Rural adaptations included accommodating distance to food sources, tailoring to local food cultures, and building community partnerships. CONCLUSIONS: Findings from this literature review provide guidance on adapting and implementing policy and environmental strategies in rural communities.

OBJECTIVE: Public health practitioners require new knowledge and skills to address the multilevel factors contributing to obesity. This article presents the systematic approach the Center of Excellence for Training and Research Translation (Center TRT) used both to assess practitioners' competencies to lead public health obesity prevention initiatives and to evaluate its annual, competency-based obesity prevention course. DESIGN: In 2006, Center TRT identified priority public health competencies for obesity prevention and then planned 7 annual courses to address the priority competencies progressively over time. Each year, a longitudinal evaluation based on Kirkpatrick's training evaluation framework was administered to course participants (n = 243) to assess perceptions of the course (daily), changes in self-reported competency (immediately pre- and postcourse), and course impact on practice over time (at 6 months). RESULTS: Participants rated the course highly for quality and relevance. Although many participants reported low levels of confidence prior to the course, following the course, at least 70% reported feeling confident to perform almost all competencies. At 6-month follow-up, the majority of participants reported completing at least 1 activity identified during course action planning. CONCLUSIONS: We identified practitioners' high-priority competency needs and then designed 7 annual courses to progressively address those needs and new needs as they arose. This approach resulted in trainings valued by practitioners and effective in increasing their sense of competence to lead public health obesity prevention initiatives. The course's continuing impact was evidenced by participants' high level of completion of their action plans at 6-month follow-up. Competency-based training is important to develop a skilled public health workforce.

PURPOSE: Obesity has reached epidemic proportions. Public health practitioners are distinctly positioned to promote the environmental changes essential to addressing obesity. The Centers for Disease Control and Prevention (CDC) and other entities provide evidence and technical assistance to support this work, yet little is known about how practitioners use evidence and support as they intervene to prevent obesity. The study's purpose was to describe how practitioners and CDC project officers characterized the obesity prevention task, where practitioners accessed support and evidence, and what approaches to support and evidence they found most useful. APPROACH OR DESIGN: Mixed-methods, cross-sectional interviews, and survey. SETTING: State-level public health obesity prevention programs. PARTICIPANTS: Public health practitioners and CDC project officers. METHOD: We conducted 10 in-depth interviews with public health practitioners (n=7) and project officers (n=3) followed by an online survey completed by 62 practitioners (50% response rate). We applied content analysis to interview data and descriptive statistics to survey data. RESULTS: Practitioners characterized obesity prevention as uncertain and complex, involving interdependence among actors, multiple levels of activity, an excess of information, and a paucity of evidence. Survey findings provide further detail on the types of evidence and support practitioners used and valued. CONCLUSION: We recommend approaches to tailoring evidence and support to the needs of practitioners working on obesity prevention and other complex health problems.

BACKGROUND: In January 2012, on the basis of an initial report from a dermatologist, we began to investigate an outbreak of tattoo-associated Mycobacterium chelonae skin and soft-tissue infections in Rochester, New York. The main goals were to identify the extent, cause, and form of transmission of the outbreak and to prevent further cases of infection. METHODS: We analyzed data from structured interviews with the patients, histopathological testing of skin-biopsy specimens, acid-fast bacilli smears, and microbial cultures and antimicrobial susceptibility testing. We also performed DNA sequencing, pulsed-field gel electrophoresis (PFGE), cultures of the ink and ingredients used in the preparation and packaging of the ink, assessment of source water and faucets at tattoo parlors, and investigation of the ink manufacturer. RESULTS: Between October and December 2011, a persistent, raised, erythematous rash in the tattoo area developed in 19 persons (13 men and 6 women) within 3 weeks after they received a tattoo from a single artist who used premixed gray ink; the highest occurrence of tattooing and rash onset was in November (accounting for 15 and 12 patients, respectively). The average age of the patients was 35 years (range, 18 to 48). Skin-biopsy specimens, obtained from 17 patients, showed abnormalities in all 17, with M. chelonae isolated from 14 and confirmed by means of DNA sequencing. PFGE analysis showed indistinguishable patterns in 11 clinical isolates and one of three unopened bottles of premixed ink. Eighteen of the 19 patients were treated with appropriate antibiotics, and their condition improved. CONCLUSIONS: The premixed ink was the common source of infection in this outbreak. These findings led to a recall by the manufacturer.

OBJECTIVE: Assess the cost-effectiveness of a 16-week weight loss intervention (Weight-Wise) for low-income midlife women. METHOD: A randomized controlled trial conducted in North Carolina in 2007 tested a weight loss intervention among 143 women (40-64 years old, mean BMI=35.1 kg/m(2)). Women were randomized to one of two arms-special intervention (n=72) and a wait-listed control group (n=71). Effectiveness measures included changes in weight, systolic and diastolic blood pressure, total cholesterol, and HDL cholesterol. Cost-effectiveness measures calculated life years gained (LYG) from changes in weight, based on excess years life lost (YLL) algorithm. RESULTS: Intervention participants had statistically significant decreases in weight (kg) (-4.4 95% CI=-5.6, -3.2) and in systolic blood pressure (-6.2 mm Hg, 95% CI=-10.6, -1.7) compared to controls. Total cost of conducting Weight-Wise was $17,403, and the cost per participant in intervention group was $242. The incremental cost per life year gained (discounted) from a decrease in obesity was $1862. CONCLUSION: Our results suggest the Weight-Wise intervention may be a cost-effective approach to improving the health of low-income women.
