Reimagining the role of health departments and their partners in addressing climate change: Revising the Building Resilience against Climate Effects (BRACE) Framework
Lemon SC , Joseph HA , Williams S , Brown C , Aytur S , Catalano K , Chacker S , Goins KV , Rudolph L , Whitehead S , Zimmerman S , Schramm PJ . Int J Environ Res Public Health 2023 20 (15) Public health departments have important roles to play in addressing the local health impacts of climate change, yet are often not well prepared to do so. The Climate and Health Program (CHP) at the Centers for Disease Control and Prevention (CDC) created the Building Resilience Against Climate Effects (BRACE) framework in 2012 as a five-step planning framework to support public health departments and their partners to respond to the health impacts of climate change. CHP has initiated a process to revise the framework to address learnings from a decade of experience with BRACE and advances in the science and practice of addressing climate and health. The aim of this manuscript is to describe the methodology for revising the BRACE framework and the expected outputs of this process. Development of the revised framework and associated guidance and tools will be guided by a multi-sector expert panel, and finalization will be informed by usability testing. Planned revisions to BRACE will (1) be consistent with the vision of Public Health 3.0 and position health departments as "chief health strategists" in their communities, who are responsible for facilitating the establishment and maintenance of cross-sector collaborations with community organizations, other partners, and other government agencies to address local climate impacts and prevent further harm to historically underserved communities; (2) place health equity as a central, guiding tenet; (3) incorporate greenhouse gas mitigation strategies, in addition to its previous focus on climate adaptation; and (4) feature a new set of tools to support BRACE implementation among a diverse set of users. The revised BRACE framework and the associated tools will support public health departments and their partners as they strive to prevent and reduce the negative health impacts of climate change for everyone, while focusing on improving health equity. |

Microb Genom 2022 8 (2) Bacterial genetic diversity is often described solely using base-pair changes despite a wide variety of other mutation types likely being major contributors. Tandem duplication/amplifications are thought to be widespread among bacteria but due to their often-intractable size and instability, comprehensive studies of these mutations are rare. We define a methodology to investigate amplifications in bacterial genomes based on read depth of genome sequence data as a proxy for copy number. We demonstrate the approach with Bordetella pertussis, whose insertion sequence element-rich genome provides extensive scope for amplifications to occur. Analysis of data for 2430 B. pertussis isolates identified 272 putative amplifications, of which 94 % were located at 11 hotspot loci. We demonstrate limited phylogenetic connection for the occurrence of amplifications, suggesting unstable and sporadic characteristics. Genome instability was further described in vitro using long-read sequencing via the Nanopore platform, which revealed that clonally derived laboratory cultures produced heterogenous populations rapidly. We extended this research to analyse a population of 1000 isolates of another important pathogen, Mycobacterium tuberculosis. We found 590 amplifications in M. tuberculosis, and like B. pertussis, these occurred primarily at hotspots. Genes amplified in B. pertussis include those involved in motility and respiration, whilst in M. tuberuclosis, functions included intracellular growth and regulation of virulence. Using publicly available short-read data we predicted previously unrecognized, large amplifications in B. pertussis and M. tuberculosis. This reveals the unrecognized and dynamic genetic diversity of B. pertussis and M. tuberculosis, highlighting the need for a more holistic understanding of bacterial genetics. |

Waters TP , Kim SY , Sharma AJ , Schnellinger P , Bobo JK , Woodruff RT , Cubbins LA , Haghiac M , Minium J , Presley L , Wolfe H , Hauguel-de Mouzon S , Adams W , Catalano PM . Diabetologia 2019 63 (2) 385-394 AIMS/HYPOTHESIS: This study aimed to determine, in women with gestational diabetes (GDM), the changes in insulin sensitivity (Matsuda Insulin Sensitivity Index; ISOGTT), insulin response and disposition index (DI) from late pregnancy (34-37 weeks gestation, T1), to early postpartum (1-5 days, T2) and late postpartum (6-12 weeks, T3). A secondary aim was to correlate the longitudinal changes in maternal lipids, adipokines, cytokines and weight in relation to the changes in ISOGTT, insulin response and DI. METHODS: ISOGTT, insulin response and DI were calculated at the three time points (T1, T2 and T3) using the results of a 75 g OGTT. Adipokines, cytokines and lipids were measured prior to each OGTT. Linear mixed-effects models were used to compare changes across each time point. Changes in ISOGTT, insulin response and DI were correlated with changes in maternal adipokines, cytokines and lipids at each time point. RESULTS: A total of 27 women completed all assessments. Compared with T1, ISOGTT was 11.20 (95% CI 8.09, 14.31) units higher at 1-5 days postpartum (p < 0.001) and was 5.49 (95% CI 2.38, 8.60) units higher at 6-12 weeks postpartum (p < 0.001). Compared with T1, insulin response values were 699.6 (95% CI 957.5, 441.6) units lower at T2 (p < 0.001) and were 356.3 (95% CI 614.3, 98.3) units lower at T3 (p = 0.004). Compared with T1, the DI was 6434.1 (95% CI 2486.2, 10,381.0) units higher at T2 (p = 0.001) and was 4262.0 (95% CI 314.6, 8209.3) units higher at T3 (p = 0.03). There was a decrease in mean cholesterol, triacylglycerol, LDL-cholesterol and VLDL-cholesterol from T1 to T2 (all p < 0.001), and an increase in mean C-reactive protein, IL-6 and IL-8 from T1 to T2 (all p < 0.001). Mean leptin decreased from T1 to T2 (p = 0.001). There was no significant change in mean adiponectin (p = 0.99) or TNF-alpha (p = 0.81) from T1 to T2. The mean maternal BMI decreased from T1 to T2 (p = 0.001) and T3 (p < 0.001). There were no significant correlations between any measure of change in ISOGTT, insulin response and DI and change in maternal cytokines, adipokines, lipids or weight from T1 to T2. CONCLUSIONS/INTERPRETATION: In women with GDM, delivery was associated with improvement in both insulin sensitivity and insulin production within the first few days. Improvement in insulin production persisted for 6-12 weeks, but insulin sensitivity deteriorated slightly. These changes in glucose metabolism were not associated to changes in lipids, leptin, inflammation markers or body weight. TRIAL REGISTRATION: ClinicalTrials.gov NCT02082301. |
Pregnant Validity of the pregnancy checkbox on death certificates in four states, and characteristics associated with pregnancy checkbox errors
Catalano A , Davis NL , Petersen EE , Harrison C , Kieltyka L , You M , Conrey EJ , Ewing AC , Callaghan WM , Goodman D . Am J Obstet Gynecol 2019 222 (3) 269 e1-269 e8 BACKGROUND: Maternal mortality rates in the United States appear to be increasing. One potential reason may be increased identification of maternal deaths after the addition of a pregnancy checkbox to the death certificate. In 2016, four state health departments (Georgia, Louisiana, Michigan, Ohio) implemented a pregnancy checkbox quality assurance pilot, with technical assistance provided by the Centers for Disease Control and Prevention. The pilot aimed to improve accuracy of the pregnancy checkbox on death certificates and resultant state maternal mortality estimates. OBJECTIVE(S): To estimate the validity of the pregnancy checkbox on the death certificate and describe characteristics associated with errors using 2016 data from a four state quality assurance pilot. STUDY DESIGN: Potential pregnancy-associated deaths were identified by linking death certificates with birth or fetal death certificates from within a year preceding death or by pregnancy checkbox status. Death certificates which indicated the decedent was pregnant within a year of death via the pregnancy checkbox, but that did not link to a birth or fetal death certificate, were referred for active follow-up to confirm pregnancy status by either death certifier confirmation or medical record review. Descriptive statistics and 95% confidence intervals were used to examine the distributions of demographic characteristics by pregnancy confirmation category (i.e., confirmed pregnant, confirmed not pregnant, and unable to confirm). We compared the proportion confirmed pregnant and confirmed not pregnant within age, race/ethnicity, pregnancy checkbox category, and certifier type categories using a Wald test of proportions. Binomial and Poisson regression models were used to estimate prevalence ratios for having an incorrect pregnancy checkbox (false positive, false negative) by age group, race/ethnicity, pregnancy checkbox category, and certifier type. RESULTS: Among 467 potential pregnancy-associated deaths, 335 (72%) were confirmed pregnant either via linkage to a birth or fetal death certificate, certifier confirmation, or review of medical records. Ninety-seven (21%) women were confirmed not pregnant (false positives) and 35 (7%) were unable to be confirmed. Women confirmed pregnant were significantly younger than women confirmed not pregnant (p<.001). Deaths certified by coroners and medical examiners were more likely to be confirmed pregnant than confirmed not pregnant (p=0.04). The association between decedent age category and false positive status followed a dose-response relationship (p<0.001), with increasing prevalence ratios for each increase in age category. Death certificates of non-Hispanic black women were more likely to be false positives, compared with non-Hispanic white women [prevalence ratio (PR) 1.41, 95% confidence interval (CI) 1.01, 1.96]. The sensitivity of the pregnancy checkbox among these four states in 2016 was 62% and the positive predictive value was 68%. CONCLUSION(S): We provide a multi-state analysis of the validity of the pregnancy checkbox and highlight a need for more accurate reporting of pregnancy status on death certificates. States and other jurisdictions may increase the accuracy of their data used to calculate maternal mortality rates by implementing quality assurance processes. |
Should women with gestational diabetes be screened at delivery hospitalization for type-2 diabetes
Waters TP , Kim SY , Werner E , Dinglas C , Carter EB , Patel R , Sharma AJ , Catalano P . Am J Obstet Gynecol 2019 222 (1) 73 e1-73 e11 BACKGROUND: Less than half of women with gestational diabetes mellitus (GDM) are screened for type 2 diabetes (DM) postpartum (PP). Other approaches to postpartum screening need to be evaluated including the role of screening during the delivery hospitalization OBJECTIVE: Our aim was to assess the performance of an oral glucose tolerance test (OGTT) administered during the delivery hospitalization compared to the OGTT administered at a 4-12 week PP visit. STUDY DESIGN: We conducted a combined analysis of patient-level data from four centers (six clinical sites) assessing the utility of an immediate postpartum 75g OGTT during the delivery hospitalization (PP1) for the diagnosis of DM compared to a routine 4-12 week postpartum OGTT (PP2). Eligible women underwent a 75g OGTT at both PP1 and PP2. Sensitivity, specificity, negative and positive predictive values of the PP1 test were estimated for diagnosis of DM, impaired fasting glucose (IFG), or impaired glucose tolerance (IGT). RESULTS: 319 women completed a PP1 screening with 152 (47.6%) lost to follow up for the PP2 OGTT. None of the women with a normal PP1 OGTT (n=73) later tested as having type 2 diabetes at PP2. Overall, 12.6% of subjects (n=21) had a change from normal to IFG/IGT or a change from IFG/IGT to DM. The PP1 OGTT had 50% sensitivity (11.8-88.2), 95.7% specificity (91.3-98.2%) with a 98.1% (94.5-99.6%) negative predictive value and a 30% (95% CI 6.7-65.3) positive predictive value for DM vs normal/IFG/IGT result. The negative predictive value of having DM at PP2 compared to a normal OGTT (excluding IFT/IGT) at PP1 was 100% (95% CI, 93.5-100) with a specificity of 96.5% (95% CI, 87.9- 99.6). CONCLUSION: A normal OGTT during the delivery hospitalization appears to exclude postpartum type-2 diabetes mellitus. However the results of the immediate postpartum OGTT were mixed when including IFG or IGT. As a majority of women do not return for postpartum diabetic screening, an OGTT during the delivery hospitalization may be of use in certain circumstances where postpartum follow up is challenging and resources could be focused on women with an abnormal screening immediately after the delivery hospitalization. |
Checking the pregnancy checkbox: Evaluation of a four-state quality assurance pilot
Daymude AEC , Catalano A , Goodman D . Birth 2019 46 (4) 648-655 BACKGROUND: The 2003 revision of the standard United States death certificate included a set of "pregnancy checkboxes" to ascertain whether a woman was pregnant at the time of her death or within the preceding year. Studies validating the pregnancy checkbox have indicated a potentially high number of errors, resulting in inflated maternal mortality rates. In response to concerns about pregnancy checkbox data quality, four state health departments implemented a quality assurance pilot project examining the accuracy of the pregnancy checkbox for 2016 deaths. METHODS: State staff conducted searches for birth or fetal death reports that matched a death certificate, within a year of death. If a pregnancy checkbox was marked, but no match was found between certificates, confirmation of the pregnancy was attempted through active follow-up with the death certifier. From December 2017 to January 2018, the quality assurance pilot was evaluated through three focus groups with key stakeholders. The evaluation aimed to describe opportunities and challenges to implementation, sustainability, and lessons learned. RESULTS: Opportunities for implementing the pilot included written documentation of the quality assurance process, improved certifier response, improved data quality, and increased data timeliness for Maternal Mortality Review Committees. Challenges included initial delays in certifier response, staff turnover, high caseloads in relation to resources, and lack of pilot prioritization in the health department. All four pilot states plan to sustain the pregnancy checkbox quality assurance process in some capacity. CONCLUSIONS: Implementing quality assurance processes for the pregnancy checkbox may ultimately improve state and national maternal death data quality. |
Levels of maternal care verification pilot: Translating guidance into practice
Zahn CM , Remick A , Catalano A , Goodman D , Kilpatrick SJ , Menard MK . Obstet Gynecol 2018 132 (6) 1401-1406 Development of systems for perinatal regionalization and for the provision of risk-appropriate maternal care is a key strategy to decrease maternal morbidity and mortality. Regionalized systems pertaining to neonatal care are broadly implemented in many states, but networks for risk-appropriate maternal care are lacking. In response to increases in maternal morbidity and mortality over the past decade, the American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM) developed and published the levels of maternal care guidelines in 2015. The guidelines are designed to promote collaboration among maternal facilities and health care providers with the goal that pregnant women receive care at a facility appropriate for their risk. The Centers for Disease Control and Prevention (CDC) developed the Levels of Care Assessment Tool in 2013 to assist states and jurisdictions in assessing maternal and neonatal levels of care in alignment with the national guidelines published by ACOG and SMFM and the American Academy of Pediatrics, respectively. With the goal of promoting levels of maternal care, ACOG and SMFM developed and piloted the levels of maternal care verification program. Fourteen facilities across three states (Georgia, Illinois, and Wyoming) participated in the pilot. A multidisciplinary team representing organizations with expertise in maternal risk-appropriate care performed an onsite comprehensive review of the maternal services available in each facility using the results from the CDC Levels of Care Assessment Tool as a previsit screening. A verification program that could be implemented on a local, state, or regional scale is being developed leveraging the lessons learned from the pilot. |
Implementing CDC's Level of Care Assessment Tool (LOCATe): A National Collaboration to Improve Maternal and Child Health
Catalano A , Bennett A , Busacker A , Carr A , Goodman D , Kroelinger C , Okoroh E , Brantley M , Barfield W . J Womens Health (Larchmt) 2017 26 (12) 1265-1269 Perinatal regionalization, or risk-appropriate care, is an approach that classifies facilities based on capabilities to ensure women and infants receive care at a facility that aligns with their risk. The CDC designed the Levels of Care Assessment Tool (LOCATe) to assist jurisdictions working in risk-appropriate care in assessing a facility's level of maternal and neonatal care aligned with the most current American College of Obstetricians and Gynecologists/Society for Maternal-Fetal Medicine (ACOG/SMFM) and American Academy of Pediatrics (AAP) guidelines. LOCATe produces standardized assessments for each hospital that participates and facilitates conversations among stakeholders in risk-appropriate care. This article describes how public health departments implement and use LOCATe in their jurisdictions. |
Worldwide application of prevention science in adolescent health
Catalano RF , Fagan AA , Gavin LE , Greenberg MT , Irwin CE Jr , Ross DA , Shek DT . Lancet 2012 379 (9826) 1653-64 The burden of morbidity and mortality from non-communicable disease has risen worldwide and is accelerating in low-income and middle-income countries, whereas the burden from infectious diseases has declined. Since this transition, the prevention of non-communicable disease as well as communicable disease causes of adolescent mortality has risen in importance. Problem behaviours that increase the short-term or long-term likelihood of morbidity and mortality, including alcohol, tobacco, and other drug misuse, mental health problems, unsafe sex, risky and unsafe driving, and violence are largely preventable. In the past 30 years new discoveries have led to prevention science being established as a discipline designed to mitigate these problem behaviours. Longitudinal studies have provided an understanding of risk and protective factors across the life course for many of these problem behaviours. Risks cluster across development to produce early accumulation of risk in childhood and more pervasive risk in adolescence. This understanding has led to the construction of developmentally appropriate prevention policies and programmes that have shown short-term and long-term reductions in these adolescent problem behaviours. We describe the principles of prevention science, provide examples of efficacious preventive interventions, describe challenges and potential solutions to take efficacious prevention policies and programmes to scale, and conclude with recommendations to reduce the burden of adolescent mortality and morbidity worldwide through preventive intervention. |
Positive youth development as a strategy to promote adolescent sexual and reproductive health
Gavin LE , Catalano RF , Markham CM . J Adolesc Health 2010 46 S1-6 Adolescents and young adults in the Unites States experience negative sexual and reproductive health outcomes, such as sexually transmitted diseases, HIV/AIDS, and pregnancy, at alarmingly high rates. Approximately 745,000 females younger than 20 years of age become pregnant every year. Birth rates among adolescents 15–19 years of age increased 3%, from 2005 to 2006 —the first increase since 1991 [1]. One in four (26%, 3.2 million) young women between 14 and 19 years of age in the United States is infected with at least one of the most common sexually transmitted infections (STIs) [2]. In addition, more than 20,000 males and females 10–24 years of age are living with HIV/AIDS [3]. | An essential part of public health is to provide America's youth with accurate, age-appropriate information about sexual risk reduction, the benefits of abstaining from sex, teen pregnancy, HIV/AIDS, and STI. A number of sex education programs have been developed and shown to effectively reduce sexual risk behavior [4]. However, there is widespread recognition that exposure to even the most effective sex education program is not enough to promote and sustain healthy adolescent sexual and reproductive health outcomes. Sex education approaches alone have short-lived and moderate effects on adolescent sexual risk behavior [5]. Therefore, in addition to evidence-based sex education, adolescents need access to clinical services, and they need efforts that build and/or support other protective factors operating in their family, school, and community [6], [7], [8], [9]. |
Future directions for positive youth development as a strategy to promote adolescent sexual and reproductive health
Catalano RF , Gavin LE , Markham CM . J Adolesc Health 2010 46 S92-6 PYD has tremendous potential to promote not only ASRH but adolescent health more broadly. This review has identified 15 tested, effective models that have demonstrated impact on ASRH; most also affected other youth outcomes, and several produced long-lasting, sustainable effects. These model programs should be prepared for broader dissemination, replication, and effectiveness trials. Broader dissemination will entail investments in developing training, technical assistance, and monitoring models that will aid in ensuring and sustaining implementation with fidelity and tracking program adaptations in broad settings. Evaluations of existing national youth-serving organizations and existing PYD programs that are unevaluated should be encouraged if they are evaluable, address the most strongly supported PYD constructs, have a clearly developed logic model that connects program elements to youth development constructs and outcomes, and program manuals are developed. Support is also provided here for the impact of youth development constructs on later ASRH outcomes, suggesting that new PYD programs, especially those targeting PYD constructs with longitudinal evidence of promotive or protective effects, should be developed and evaluated to identify long-term results. There is much work to be done on examining the ability of PYD constructs to impact ASRH. While there is sufficient evidence for a number of PYD constructs, more longitudinal research is needed. We have argued here that investigation of existing longitudinal datasets may efficiently increase our understanding of the evidence for the promotive and protective effects of understudied constructs or those with mixed evidence. Further, there is a need for the development of standardized measures of PYD constructs and the development and use of measures of positive sexual and reproductive health outcomes. We also recommend that future studies compare the relative strength of the PYD constructs and devote more resources to understanding how these constructs work together to promote ASRH. |
A review of positive youth development programs that promote adolescent sexual and reproductive health
Gavin LE , Catalano RF , David-Ferdon C , Gloppen KM , Markham CM . J Adolesc Health 2010 46 S75-91 PURPOSE: Positive youth development (PYD) may be a promising strategy for promoting adolescent health. A systematic review of the published data was conducted to identify and describe PYD programs that improve adolescent sexual and reproductive health. METHODS: Eight databases were searched for articles about PYD programs published between 1985 and 2007. Programs included met the following criteria: fostered at least one of 12 PYD goals in multiple socialization domains (i.e., family, school, community) or addressed two or more goals in at least one socialization domain; allocated at least half of the program activities to promoting general PYD outcomes (as compared with a focus on direct sexual health content); included youth younger than 20 years old; and used an experimental or quasi-experimental evaluation design. RESULTS: Thirty programs met the inclusion criteria, 15 of which had evidence of improving at least one adolescent sexual and reproductive health outcome. Program effects were moderate and well-sustained. Program goals addressed by approximately 50% or more of the effective programs included promoting prosocial bonding, cognitive competence, social competence, emotional competence, belief in the future, and self-determination. Effective programs were significantly more likely than those that did not have an impact to strengthen the school context and to deliver activities in a supportive atmosphere. Effective programs were also more likely to build skills, enhance bonding, strengthen the family, engage youth in real roles and activities, empower youth, communicate expectations, and be stable and relatively long-lasting, although these differences between effective and ineffective programs were not statistically significant. CONCLUSION: PYD programs can promote adolescent sexual and reproductive health, and tested, effective PYD programs should be part of a comprehensive approach to promoting adolescent health. However, more research is needed before a specific list of program characteristics can be viewed as a "recipe" for success. |
