Recapitulation of human pathophysiology and identification of forensic biomarkers in a translational model of chlorine inhalation injury
Achanta S , Gentile MA , Albert CJ , Schulte KA , Pantazides BG , Crow BS , Quinones-Gonzalez J , Perez JW , Ford DA , Patel RP , Blake TA , Gunn MD , Jordt SE . Am J Physiol Lung Cell Mol Physiol 2024 Chlorine gas (Cl(2)) has been repeatedly used as a chemical weapon, first in World War I and most recently in Syria. Life-threatening Cl(2) exposures frequently occur in domestic and occupational environments, and in transportation accidents. Modeling the human etiology of Cl(2)-induced acute lung injury (ALI), forensic biomarkers, and targeted countermeasures development have been hampered by inadequate large animal models. The objective of this study was to develop a translational model of Cl(2)-induced ALI in swine to understand toxico-pathophysiology and is suitable for screening potential medical countermeasures, and identify biomarkers useful for forensic analysis. Specific pathogen-free Yorkshire swine (30-40 kg) of either sex were exposed to Cl(2) (≤ 240 ppm for 1 h) or filtered air under anesthesia and controlled mechanical ventilation. Exposure to Cl(2) resulted in severe hypoxia and hypoxemia, increased airway resistance and peak inspiratory pressure, and decreased dynamic lung compliance. Cl(2) exposure resulted in increased total leucocyte and neutrophil counts in bronchoalveolar lavage fluid (BALF), vascular leakage, and pulmonary edema compared to the air-exposed group. The model recapitulated all three key histopathological features of human ALI, such as neutrophilic alveolitis, deposition of hyaline membranes, and formation of microthrombi. Free and lipid-bound 2‑chlorofatty acids and chlorotyrosine-modified proteins (3-chloro-L-tyrosine and 3,5-dichloro-L-tyrosine) were detected in plasma and lung tissue after Cl(2)‑exposure. In this study, we developed a translational swine model that recapitulates key features of human Cl(2) inhalation injury and is suitable for testing medical countermeasures, and validated chlorinated fatty acids and protein adducts as biomarkers of Cl(2) inhalation. |
Recapitulation of Human Pathophysiology and Identification of Forensic Biomarkers in a Translational Swine Model of Chlorine Inhalation Injury (preprint)
Achanta S , Gentile MA , Albert CJ , Schulte KA , Pantazides BG , Crow BS , Quinones-Gonzalez J , Perez JW , Ford DA , Patel RP , Blake TA , Gunn MD , Jordt SE . bioRxiv 2022 10 Rationale: Chlorine gas (Cl<inf>2</inf>) has been repeatedly used as a chemical weapon, first in World War I and most recently in Syria. Life-threatening Cl<inf>2</inf> exposures frequently occur in domestic and occupational environments, and in transportation accidents. There is a knowledge gap in large animal models of Cl<inf>2</inf>-induced acute lung injury (ALI) required to accurately model human etiology and for the development of targeted countermeasures Objective: To develop a translational model of Cl<inf>2</inf>-induced ALI in swine to study toxicopathophysiology and identify biomarkers useful for forensic analysis. Method(s): Specific pathogen-free Yorkshire swine (30-40 kg) of either sex were exposed to Cl<inf>2</inf> gas (<= 240 ppm for 1 h) or filtered air under anesthesia and controlled mechanical ventilation. Result(s): Exposure to Cl<inf>2</inf> resulted in severe hypoxia and hypoxemia, increased airway resistance and peak inspiratory pressure, and decreased dynamic lung compliance. Chlorine exposure resulted in increased total BALF and neutrophil counts, vascular leakage, and edema compared to the control group. The model recapitulated all three key histopathological features of human ALI, such as neutrophilic alveolitis, deposition of hyaline membranes, and formation of microthrombi. Free and lipid-bound 2-chlorofatty acids and chlorotyrosine-modified proteins (3-chloro-L-tyrosine and 3,5-dichloro-L-tyrosine) were detected in plasma and lung after Cl<inf>2</inf>-exposure. Conclusion(s): The translational model developed in this study replicates key features of humans exposed to Cl<inf>2</inf> and is suitable to test medical countermeasures. Specific biomarkers of Cl<inf>2</inf> exposure have been identified in plasma and lung tissue samples.

Voices of Black talent in chemistry: Retention strategies and personal success stories
Scott T , Adderley D , Ali Y , Amanuel M , Blake A , Callender M , Carter C , Fokwa HD , Gooden RO , Granger A , Gunn K , Henderson A , Kitimet M , Modeste E , Stewart Z , Teah J , Wairegi S , Ward LW , Parish CA . J Am Chem Soc 2023 145 (23) 12426-12428 Juneteenth, a federal holiday officially recognized in 2021, is celebrated annually in the United States to honor the emancipation of enslaved Black Americans. As a symbol of racial justice, equality, and equity, Juneteenth represents an opportunity to pay tribute to the achievements of a wide range of Black chemistry students and the initiatives taken to promote the success of every student within an environment that has historically not been inclusive. | | While the U.S. STEM workforce has become more diverse in the past 10 years, Black people continue to be underrepresented in science, and in chemistry, in particular. The recent National Science Foundation report Diversity and STEM: Women, Minorities and Persons with Disabilities 2023 shows that only 9% of the STEM workforce identifies as Black, 3 percentage points (roughly 7.7M people (1)) lower than their overall representation in the adult U.S. population. (2) The U.S. Bureau of Labor Statistics paints a similar picture─in 2022 only 10% of the chemical manufacturing workforce was Black. (3) Chemical & Engineering News culled the chemistry data from the 2023 NSF report revealing even bleaker figures─in 2021, Black people comprised only 4.4% of employed chemists, (4) and were more likely to occupy lower paying STEM jobs that do not require a college degree. (2) | | Recent publications have emphasized the importance of scientists and scientific institutions welcoming and supporting the development of individuals from groups historically marginalized in fields such as chemistry, biology, mathematics, computer science, and physics. (5) Not only is such intentional support a moral imperative, but numerous reports have demonstrated that increasing diversity and inclusion in these fields leads to a more innovative and productive scientific community. (6) | | Marginalized groups often face systemic barriers to accessing education and career opportunities, resulting in a chemical workforce that lacks diversity. To address this, chemists and chemistry organizations have taken steps to actively support and mentor individuals from historically excluded groups, providing access to resources and opportunities, and promoting a culture of inclusivity in academia and the workplace. For instance, since 1965, the American Chemical Society (ACS) Project Seed program has provided summer research experiences for more than 11,000 high school students, while the ACS Scholars program has provided renewable scholarships for more than 3,500 undergraduates interested in chemistry-related careers. |
Meeting the Healthy People 2030 added sugars target
Stowe EW , Moore LV , Hamner HC , Park S , Gunn JP , Juan W , Kantor MA , Galuska DA . Am J Prev Med 2023 65 (1) 4-11 INTRODUCTION: Many Americans exceed the dietary recommendations for added sugars. Healthy People 2030 set a population target mean of 11.5% calories from added sugars for persons aged ≥2 years. This paper describes the reductions needed in population groups with varying added sugars intake to meet this target using 4 different public health approaches. METHODS: Data from the 2015-2018 National Health and Nutrition Examination Survey (n=15,038) and the National Cancer Institute method were used to estimate the usual percentage calories from added sugars. Four approaches investigated lowering intake among (1) the general U.S. population, (2) people exceeding the 2020-2025 Dietary Guidelines for Americans recommendation for added sugars (≥10% calories/day), (3) high consumers of added sugars (≥15% calories/day), or (4) people exceeding the Dietary Guidelines for Americans recommendation for added sugars with 2 different reductions on the basis of added sugars intake. Added sugars intake was examined before and after reduction by sociodemographic characteristics. RESULTS: To meet the Healthy People 2030 target using the 4 approaches, added sugars intake needs to decrease by an average of (1) 13.7 calories/day for the general population; (2) 22.0 calories/day for people exceeding the Dietary Guidelines for Americans recommendation; (3) 56.6 calories/day for high consumers; or (4) 13.9 and 32.3 calories/day for people consuming 10 to <15% and ≥15% calories from added sugars, respectively. Differences in added sugars intake were observed before and after reduction by race/ethnicity, age, and income. CONCLUSIONS: The Healthy People 2030 added sugars target is achievable with modest reductions in added sugars intake, ranging from 14 to 57 calories/day depending on the approach. |
Systematic review of social determinants of health associated with HIV testing among Hispanic/Latino gay, bisexual, and other men who have sex with men in the United States
Crepaz N , Salabarría-Peña Y , Mullins MM , Gunn JKL , Higa DH . AIDS Educ Prev 2023 35 (1) 36-s6 This systematic review synthesized published literature (January 2008-October 2021) about the association between social determinants of health (SDOH) and HIV testing among Hispanic/Latino gay, bisexual, and other men who have sex with men (HLMSM), a group disproportionally affected by HIV. Having higher education than a high school diploma, health insurance and access to health care services, and visiting a health care provider in the past 12 months were some of the determinants associated with HIV testing, while limited English proficiency was associated with reduced odds of HIV-testing among HLMSM. More research is needed to understand the relationship of SDOH (especially neighborhood) and HIV testing, how SDOH may affect HIV testing among different HLMSM groups, and how to increase self-testing and use of e-health in this priority population. Additionally, culturally and linguistically appropriate multilevel interventions and health services for HLMSM are urgently needed to diagnose HIV as early as possible after infection. |

Ann N Y Acad Sci 2022 1518 (1) 209-225 The COVID-19 pandemic caught the world largely unprepared, including scientific and policy communities. On April 10-13, 2022, researchers across academia, industry, government, and nonprofit organizations met at the Keystone symposium "Lessons from the Pandemic: Responding to Emerging Zoonotic Viral Diseases" to discuss the successes and challenges of the COVID-19 pandemic and what lessons can be applied moving forward. Speakers focused on experiences not only from the COVID-19 pandemic but also from outbreaks of other pathogens, including the Ebola virus, Lassa virus, and Nipah virus. A general consensus was that investments made during the COVID-19 pandemic in infrastructure, collaborations, laboratory and manufacturing capacity, diagnostics, clinical trial networks, and regulatory enhancements-notably, in low-to-middle income countries-must be maintained and strengthened to enable quick, concerted responses to future threats, especially to zoonotic pathogens. |
Strategies to improve HIV care outcomes for people with HIV who are out of care: a meta-analysis
Higa DH , Crepaz N , Mullins MM , Adegbite-Johnson A , Gunn JKL , Denard C , Mizuno Y . AIDS 2022 36 (6) 853-862 OBJECTIVE: The aim of this study was to evaluate the effectiveness of five intervention strategies: patient navigation, appointment help/alerts, psychosocial support, transportation/appointment accompaniment, and data-to-care on HIV care outcomes among persons with HIV (PWH) who are out of care (OOC). DESIGN: A systematic review with meta-analysis. METHODS: We searched CDC's Prevention Research Synthesis (PRS) Project's cumulative HIV database to identify intervention studies conducted in the U.S., published between 2000 and 2020 that included comparisons between groups or prepost, and reported at least one relevant outcome (i.e., re-engagement and retention in HIV care, and viral suppression). Effect sizes were meta-analyzed using random-effect models to assess intervention effectiveness. RESULTS: Thirty-nine studies reporting on 42 unique interventions met the inclusion criteria. Overall, intervention strategies are effective in improving re-engagement in care [odds ratio (OR) = 1.79; 95% confidence interval (95% CI): 1.36-2.36, k = 14], retention in care (OR = 2.01; 95% CI: 1.64-2.64, k = 22), and viral suppression (OR = 2.50; 95% CI: 1.87-3.34, k = 27). Patient navigation, appointment help/alerts, psychosocial support, and transportation/appointment accompaniment improved all three HIV care outcomes. Data-to-care improved re-engagement and retention but had insufficient evidence for viral suppression. CONCLUSION: Several strategies are effective for improving HIV care outcomes among PWH who are OOC. More work is still needed for consistent definitions of OCC and HIV care outcomes, better reporting of intervention and cost data, and identifying how best to implement and scale-up effective strategies to engage and retain OOC PWH in care and reach the ending the HIV epidemic goals. |

J Clin Microbiol 2021 60 (1) Jcm0174221 Point-of-care antigen tests are an important tool for SARS-CoV-2 detection. Antigen tests are less sensitive than real-time reverse-transcriptase PCR (rRT-PCR). Data on the performance of the BinaxNOW antigen test compared to rRT-PCR and viral culture by symptom and known exposure status, timing during disease or exposure period and demographic variables are limited. During November 3(rd)-17(th), 2020, we collected paired upper respiratory swab specimens to test for SARS-CoV-2 by rRT-PCR and Abbott BinaxNOW (BinaxNOW) antigen test at two community testing sites in Pima County, Arizona. We administered a questionnaire to capture symptoms, known exposure status and previous SARS-CoV-2 test results. Specimens positive by either test were analyzed by viral culture. Previously we showed overall BinaxNOW sensitivity was 52.5%. Here we showed BinaxNOW sensitivity increased to 65.7% among currently symptomatic individuals reporting a known exposure. BinaxNOW sensitivity was lower among participants with a known exposure and previously symptomatic (32.4%) or never symptomatic (47.1%) within 14 days of testing. Sensitivity was 71.1% in participants within a week of symptom onset. In participants with a known exposure, sensitivity was highest 8-10 days post-exposure (75%). The positive predictive value for recovery of virus in cell culture was 56.7% for BinaxNOW-positive and 35.4% for rRT-PCR-positive specimens. Result reporting time was 2.5 hours for BinaxNOW and 26 hours for rRT-PCR. Point-of-care antigen tests have a shorter turn-around time compared to laboratory-based nucleic acid amplification tests, which allows for more rapid identification of infected individuals. Antigen test sensitivity limitations are important to consider when developing a testing program. |

Int J Infect Dis 2021 112 25-34 BACKGROUND: The lower-than-expected COVID-19 morbidity and mortality in Africa has been attributed to multiple factors, including weak surveillance. We estimated the burden of SARS-CoV-2 infections eight months into the epidemic in Nairobi, Kenya. METHODS: We conducted a population-based cross-sectional survey using multi-stage random sampling to select households within Nairobi in November 2020. Sera from consenting household members were tested for antibodies to SARS-CoV-2. Seroprevalence was estimated after adjusting for population structure and test performance. Infection fatality ratios (IFRs) were calculated by comparing study estimates to reported cases and deaths. RESULTS: Among 1,164 individuals, the adjusted seroprevalence was 34.7% (95%CI 31.8-37.6). Half the enrolled households had at least one positive participant. Seropositivity increased in more densely populated areas (spearman's r=0.63; p=0.009). Individuals aged 20-59 years had at least 2-fold higher seropositivity than those aged 0-9 years. The IFR was 40 per 100,000 infections, with individuals ≥60 years old having higher IFRs. CONCLUSION: Over one-third of Nairobi residents had been exposed to SARS-CoV-2 by November 2020, indicating extensive transmission. However, the IFR was >10-fold lower than that reported in Europe and the United States, supporting the perceived lower morbidity and mortality in sub-Saharan Africa. |
A rapid review of disparities in HIV prevention and care outcomes among Hispanic/Latino men who have sex with men in the United States
Crepaz N , Mullins MM , Higa D , Gunn JKL , Salabarría-Peña Y . AIDS Educ Prev 2021 33 (4) 276-289 In the United States, Hispanic/Latino men who have sex with men (HLMSM) are disproportionally affected by HIV. We conducted a rapid review of national surveillance data to examine disparities in HIV prevention and care outcomes among HLMSM. Thirteen reports provided relevant data from 2011 to 2018. Compared to White MSM, a higher percentage of HIV-negative HLMSM reported not taking PrEP and engaging in condomless sex; a lower percentage of HIV-negative HLMSM at risk for HIV reported PrEP awareness and use; and a lower percentage of HIV-positive HLMSM were aware of their status, linked to HIV care, and virally suppressed. Viral suppression rates in HLMSM were better among Ryan White clients than the national rates, suggesting that access to comprehensive care/services reduces disparities. Findings also call for identifying individual, social, and structural factors contributing to condomless sex without PrEP use and HIV status unawareness and identifying best approaches for scaling up comprehensive care/services. |
Effectiveness of HIV Stigma Interventions for Men who have Sex with Men (MSM) With and Without HIV in the United States: A Systematic Review and Meta-Analyses
Gunn JKL , Rooks-Peck C , Wichser ME , Denard C , McCree DH , Jeffries WL4th , DeLuca JB , Ross LW , Herron A , Barham T , Flores SA , Higa DH . AIDS Behav 2021 26 51-89 Stigma may contribute to HIV disparities for men who have sex with men (MSM). This systematic review quantified the effects of HIV stigma interventions for MSM on stigma and sex risk. We conducted a systematic search to identify US-based studies published between 2000 and June 2019 focused on HIV and MSM, and either measured stigma pre-post or included a stigma intervention component. Twenty-nine articles, representing 26 unique studies met inclusion criteria. Random effect models showed no intervention effect for reducing stigma and a non-significant increase in HIV testing. Significant decreases in condomless sex with males, condomless sex with females, and substance-influenced sex were found. Few intervention studies measured stigma pre-post. Findings suggest that including a stigma reduction component in interventions can improve HIV testing and reduce sex risk for MSM. Developing interventions to address stigma may be important in decreasing HIV infection among MSM and ending the HIV epidemic. |

Cell Rep Med 2021 2 (4) 100237 The failure to mount an antibody response following viral infection or seroconversion failure is a largely underappreciated and poorly understood phenomenon. Here, we identified immunologic markers associated with robust antibody responses after influenza virus infection in two independent human cohorts, SHIVERS and FLU09, based in Auckland, New Zealand and Memphis, Tennessee, USA, respectively. In the SHIVERS cohort, seroconversion significantly associates with (1) hospitalization, (2) greater numbers of proliferating, activated CD4+ T cells, but not CD8+ T cells, in the periphery during the acute phase of illness, and (3) fewer inflammatory monocytes (CD14hiCD16+) by convalescence. In the FLU09 cohort, fewer CD14hiCD16+ monocytes during early illness in the nasal mucosa were also associated with the generation of influenza-specific mucosal immunoglobulin A (IgA) and IgG antibodies. Our study demonstrates that seroconversion failure after infection is a definable immunological phenomenon, associated with quantifiable cellular markers that can be used to improve diagnostics, vaccine efficacy, and epidemiologic efforts. |

Am J Public Health 2021 111 (5) e1-e10 Objectives. To assess SARS-CoV-2 transmission within a correctional facility and recommend mitigation strategies.Methods. From April 29 to May 15, 2020, we established the point prevalence of COVID-19 among incarcerated persons and staff within a correctional facility in Arkansas. Participants provided respiratory specimens for SARS-CoV-2 testing and completed questionnaires on symptoms and factors associated with transmission.Results. Of 1647 incarcerated persons and 128 staff tested, 30.5% of incarcerated persons (range by housing unit = 0.0%-58.2%) and 2.3% of staff tested positive for SARS-CoV-2. Among those who tested positive and responded to symptom questions (431 incarcerated persons, 3 staff), 81.2% and 33.3% were asymptomatic, respectively. Most incarcerated persons (58.0%) reported wearing cloth face coverings 8 hours or less per day, and 63.3% reported close contact with someone other than their bunkmate.Conclusions. If testing remained limited to symptomatic individuals, fewer cases would have been detected or detection would have been delayed, allowing transmission to continue. Rapid implementation of mass testing and strict enforcement of infection prevention and control measures may be needed to mitigate spread of SARS-CoV-2 in this setting. (Am J Public Health.

Evaluation of Abbott BinaxNOW Rapid Antigen Test for SARS-CoV-2 Infection at Two Community-Based Testing Sites - Pima County, Arizona, November 3-17, 2020.
Prince-Guerra JL , Almendares O , Nolen LD , Gunn JKL , Dale AP , Buono SA , Deutsch-Feldman M , Suppiah S , Hao L , Zeng Y , Stevens VA , Knipe K , Pompey J , Atherstone C , Bui DP , Powell T , Tamin A , Harcourt JL , Shewmaker PL , Medrzycki M , Wong P , Jain S , Tejada-Strop A , Rogers S , Emery B , Wang H , Petway M , Bohannon C , Folster JM , MacNeil A , Salerno R , Kuhnert-Tallman W , Tate JE , Thornburg NJ , Kirking HL , Sheiban K , Kudrna J , Cullen T , Komatsu KK , Villanueva JM , Rose DA , Neatherlin JC , Anderson M , Rota PA , Honein MA , Bower WA . MMWR Morb Mortal Wkly Rep 2021 70 (3) 100-105 Rapid antigen tests, such as the Abbott BinaxNOW COVID-19 Ag Card (BinaxNOW), offer results more rapidly (approximately 15-30 minutes) and at a lower cost than do highly sensitive nucleic acid amplification tests (NAATs) (1). Rapid antigen tests have received Food and Drug Administration (FDA) Emergency Use Authorization (EUA) for use in symptomatic persons (2), but data are lacking on test performance in asymptomatic persons to inform expanded screening testing to rapidly identify and isolate infected persons (3). To evaluate the performance of the BinaxNOW rapid antigen test, it was used along with real-time reverse transcription-polymerase chain reaction (RT-PCR) testing to analyze 3,419 paired specimens collected from persons aged ≥10 years at two community testing sites in Pima County, Arizona, during November 3-17, 2020. Viral culture was performed on 274 of 303 residual real-time RT-PCR specimens with positive results by either test (29 were not available for culture). Compared with real-time RT-PCR testing, the BinaxNOW antigen test had a sensitivity of 64.2% for specimens from symptomatic persons and 35.8% for specimens from asymptomatic persons, with near 100% specificity in specimens from both groups. Virus was cultured from 96 of 274 (35.0%) specimens, including 85 (57.8%) of 147 with concordant antigen and real-time RT-PCR positive results, 11 (8.9%) of 124 with false-negative antigen test results, and none of three with false-positive antigen test results. Among specimens positive for viral culture, sensitivity was 92.6% for symptomatic and 78.6% for asymptomatic individuals. When the pretest probability for receiving positive test results for SARS-CoV-2 is elevated (e.g., in symptomatic persons or in persons with a known COVID-19 exposure), a negative antigen test result should be confirmed by NAAT (1). Despite a lower sensitivity to detect infection, rapid antigen tests can be an important tool for screening because of their quick turnaround time, lower costs and resource needs, high specificity, and high positive predictive value (PPV) in settings of high pretest probability. The faster turnaround time of the antigen test can help limit transmission by more rapidly identifying infectious persons for isolation, particularly when used as a component of serial testing strategies. |
Multidisciplinary Community-Based Investigation of a COVID-19 Outbreak Among Marshallese and Hispanic/Latino Communities - Benton and Washington Counties, Arkansas, March-June 2020.
Center KE , Da Silva J , Hernandez AL , Vang K , Martin DW , Mazurek J , Lilo EA , Zimmerman NK , Krow-Lucal E , Campbell EM , Cowins JV , Walker C , Dominguez KL , Gallo B , Gunn JKL , McCormick D , Cochran C , Smith MR , Dillaha JA , James AE . MMWR Morb Mortal Wkly Rep 2020 69 (48) 1807-1811 By June 2020, Marshallese and Hispanic or Latino (Hispanic) persons in Benton and Washington counties of Arkansas had received a disproportionately high number of diagnoses of coronavirus disease 2019 (COVID-19). Despite representing approximately 19% of these counties' populations (1), Marshallese and Hispanic persons accounted for 64% of COVID-19 cases and 57% of COVID-19-associated deaths. Analyses of surveillance data, focus group discussions, and key-informant interviews were conducted to identify challenges and propose strategies for interrupting transmission of SARS-CoV-2, the virus that causes COVID-19. Challenges included limited native-language health messaging, high household occupancy, high employment rate in the poultry processing industry, mistrust of the medical system, and changing COVID-19 guidance. Reducing the COVID-19 incidence among communities that suffer disproportionately from COVID-19 requires strengthening the coordination of public health, health care, and community stakeholders to provide culturally and linguistically tailored public health education, community-based prevention activities, case management, care navigation, and service linkage. |
Characteristics and Outcomes of Contacts of COVID-19 Patients Monitored Using an Automated Symptom Monitoring Tool - Maine, May-June 2020.
Krueger A , Gunn JKL , Watson J , Smith AE , Lincoln R , Huston SL , Dirlikov E , Robinson S . MMWR Morb Mortal Wkly Rep 2020 69 (31) 1026-1030 SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is spread from person to person (1-3). Quarantine of exposed persons (contacts) for 14 days following their exposure reduces transmission (4-7). Contact tracing provides an opportunity to identify contacts, inform them of quarantine recommendations, and monitor their symptoms to promptly identify secondary COVID-19 cases (7,8). On March 12, 2020, Maine Center for Disease Control and Prevention (Maine CDC) identified the first case of COVID-19 in the state. Because of resource constraints, including staffing, Maine CDC could not consistently monitor contacts, and automated technological solutions for monitoring contacts were explored. On May 14, 2020, Maine CDC began enrolling contacts of patients with reported COVID-19 into Sara Alert (MITRE Corporation, 2020),* an automated, web-based, symptom monitoring tool. After initial communication with Maine CDC staff members, enrolled contacts automatically received daily symptom questionnaires via their choice of e-mailed weblink, text message, texted weblink, or telephone call until completion of their quarantine. Epidemiologic investigations were conducted for enrollees who reported symptoms or received a positive SARS-CoV-2 test result. During May 14-June 26, Maine CDC enrolled 1,622 contacts of 614 COVID-19 patients; 190 (11.7%) eventually developed COVID-19, highlighting the importance of identifying, quarantining, and monitoring contacts of COVID-19 patients to limit spread. In Maine, symptom monitoring was not feasible without the use of an automated symptom monitoring tool. Using a tool that permitted enrollees to specify a method of symptom monitoring was well received, because the majority of persons monitored (96.4%) agreed to report using this system. |
Characteristics of persons who report using only nicotine-containing products among interviewed patients with e-cigarette, or vaping, product use-associated lung injury - Illinois, August-December 2019
Ghinai I , Navon L , Gunn JKL , Duca LM , Brister S , Love S , Brink R , Fajardo G , Johnson J , Saathoff-Huber L , King BA , Jones CM , Krishnasamy VP , Layden JE . MMWR Morb Mortal Wkly Rep 2020 69 (3) 84-89 In 2019, the United States experienced an outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). Most EVALI patients have reported using tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, products obtained from informal sources (2,3), and vitamin E acetate in these products has been closely linked with EVALI (4,5). However, some EVALI patients report using only nicotine-containing products. This study compared demographic, product use, and clinical characteristics of EVALI patients in Illinois who reported using only nicotine-containing e-cigarette, or vaping, products with those of patients who reported using any THC-containing products. Among 121 interviewed Illinois EVALI patients, 17 (14%) reported using only nicotine-containing products, including nine (7%) patients who had no indication of any THC use, based on self-report or toxicology testing. Compared with patients who used any THC-containing products, these nine patients were significantly more likely to be older and female and were less likely to experience constitutional symptoms or to have leukocytosis on initial evaluation. Although vitamin E acetate has been strongly linked with EVALI, evidence is not sufficient to rule out the contribution of other chemicals of concern, including chemicals in either THC- or non-THC-containing products, in some reported EVALI cases. The contributing cause or causes of EVALI for patients reporting use of only nicotine-containing products warrants further investigation. |
Addressing childhood obesity for type 2 diabetes prevention: Challenges and opportunities
Galuska DA , Gunn JP , O'Connor AE , Petersen R . Diabetes Spectr 2018 31 (4) 330-335 IN BRIEF Addressing the problem of childhood obesity is an important component of preventing type 2 diabetes. Although children and their families ultimately make decisions about diet, physical activity, and obesity management, many groups have a role in making these choices easier. They do this by providing families with tools and resources and by implementing policies and practices that support a healthy diet and physical activity in the places where children and their families spend their time. Diabetes educators are an important part of the solution. |

J Infect Dis 2018 219 (3) 347-357 Background: Understanding the attack rate of influenza infection and the proportion who become ill by risk group is key to implementing prevention measures. While population-based studies of anti-haemagglutinin antibody responses have been described previously, studies examining both anti-haemagglutinin and anti-neuraminidase antibodies are lacking. Methods: In 2015, we conducted a sero-epidemiologic cohort study of individuals randomly selected from a population in New Zealand. We tested paired sera for haemagglutinin-inhibition (HAI) or neuraminidase-inhibition (NAI) titres for seroconversion . We followed participants weekly and performed influenza PCR for those reporting influenza-like illness (ILI). Results: Influenza infection (either HAI or NAI seroconversion) was found in 321 (35%; 95%CI:32-38%) of 911 unvaccinated participants, of which 100 (31%) seroconverted to NAI alone. Young children and Pacific peoples experienced the highest influenza infection attack rates, but overall only a quarter of all infected reported influenza-PCR-confirmed ILI and one-quarter of these sought medical attention. Seroconversion to NAI alone was higher among children aged <5 years vs. those aged >/=5 years (14% vs 4%; p<0.001) and among those with influenza B vs A(H3N2) virus infections (7% vs 0.3%; p<0.001). Conclusions: Measurement of anti-neuraminidase antibodies in addition to anti- hemagglutinin antibodies may be important in capturing the true influenza infection rates. |
CDC's Active People, Healthy Nation(SM): Creating an Active America, Together
Fulton JE , Buchner DM , Carlson SA , Borbely D , Rose KM , O'Connor AE , Gunn JP , Petersen R . J Phys Act Health 2018 15 (7) 469-473 Physical activity can reduce the risk of at least 20 chronic diseases and conditions and provide effective treatment for many of these conditions. Yet, physical activity levels of Americans remain low, with only small improvements over 20 years. The Centers for Disease Control and Prevention (CDC) considered what would accelerate progress and, as a result, developed Active People, Healthy Nation(SM), an aspirational initiative to improve physical activity in 2.5 million high school youth and 25 million adults, doubling the 10-year improvement targets of Healthy People 2020. Active People, Healthy Nation(SM) will implement evidence-based guidance to improve physical activity through 5 action steps centered on core public health functions: (1) program delivery, (2) partnership mobilization, (3) effective communication, (4) cross-sectoral training, and (5) continuous monitoring and evaluation. To achieve wide-scale impact, Active People, Healthy Nation(SM) will need broad engagement from a variety of sectors working together to coordinate activities and initiatives. |
Using syndromic surveillance for all-hazards public health surveillance: Successes, challenges, and the future
Yoon PW , Ising AI , Gunn JE . Public Health Rep 2017 132 3s-6s Fifteen years have passed since the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 called for the establishment of nationwide surveillance and reporting mechanisms to detect bioterrorism-related events.1,2 In the 1990s, several health departments established surveillance systems to detect prediagnostic (ie, before diagnoses are confirmed) signs and symptoms for the early identification of disease occurrences. However, it was the 2002 act, following the September 11 and anthrax attacks, that provided the impetus and resources for the growth of syndromic surveillance across the country.3–5 Syndromic surveillance is now a core component of many US health departments’ surveillance activities. Public health practitioners use it daily to identify potential events of public health concern, track disease trends, and inform responses to confirmed and rumored events. Syndromic surveillance also provides real-time information for health events that are not supported by case reporting or laboratory reporting, such as injuries and suicidality. | This supplemental issue of Public Health Reports contains 18 articles that describe the use of syndromic surveillance for event identification, situational awareness, and enhanced response to diseases, conditions, and activities that affect population health. The data used in syndromic surveillance can come from various sources, but the articles in this supplement focus on the use of electronic health record (EHR) data from clinical settings. The articles describe the value of real-time data for public health decision making and the challenges of collecting and interpreting data that are generated primarily for health care practice and billing purposes. |
Sodium, sugar, and fat content of complementary infant and toddler foods sold in the United States, 2015
Maalouf J , Cogswell ME , Bates M , Yuan K , Scanlon KS , Pehrsson P , Gunn JP , Merritt RK . Am J Clin Nutr 2017 105 (6) 1443-1452 Background: As part of a healthy diet, limiting intakes of excess sodium, added sugars, saturated fat, and trans fat has been recommended. The American Heart Association recommends that children aged <2 y should avoid added sugars.Objective: We sought to determine commercial complementary infant-toddler food categories that were of potential concern because of the sodium, added sugar, saturated fat, or trans fat content.Design: Nutrition label information (e.g., serving size, sodium, saturated fat, trans fat) for 1032 infant and toddler foods was collected from manufacturers' websites and stores from May to July 2015 for 24 brands, which accounted for >95% of infant-toddler food sales. The presence of added sugars was determined from the ingredient list. Reference amount customarily consumed (RACC) categories were used to group foods and standardize serving sizes. A high sodium content was evaluated on the basis of the Upper Intake Level for children aged 1-3 y and the number of potential servings per day ([i.e., 1500 mg/7 servings (>210 mg/RACC)], a sodium amount >200 mg/100 g, or a mean sodium density >1000 mg/1000 kcal.Results: In 2015, most commercial infant-only vegetables, fruit, dinners, and cereals were low in sodium, contained no saturated fat, and did not contain added sugars. On average, toddler meals contained 2233 mg Na/1000 kcal, and 84% of the meals had >210 mg Na/RACC (170 g), whereas 69% of infant-toddler savory snacks had >200 mg Na/100 g. More than 70% of toddler's meals, cereal bars and breakfast pastries, and infant-toddler grain- or dairy-based desserts contained ≥1 sources of added sugar. Approximately 70% of toddler meals contained saturated fat (mean: 1.9 g/RACC), and no commercial infant-toddler foods contained trans fats.Conclusion: Most commercial toddler meals, cereal bars and breakfast pastries, and infant-toddler snacks and desserts have high sodium contents or contain added sugars, suggesting a need for continued public health efforts to support parents in choosing complementary foods for their infants and toddlers. |

Reid M , Gunn J , Shah S , Donovan M , Eggo R , Babin S , Stajner I , Rogers E , Ensor KB , Raun L , Levy JI , Painter I , Phipatanakul W , Yip F , Nath A , Streichert LC , Tong C , Burkom H . Online J Public Health Inform 2016 8 (3) e199 This paper continues an initiative conducted by the International Society for Disease Surveillance with funding from the Defense Threat Reduction Agency to connect near-term analytical needs of public health practice with technical expertise from the global research community. The goal is to enhance investigation capabilities of day-to-day population health monitors. A prior paper described the formation of consultancies for requirements analysis and dialogue regarding costs and benefits of sustainable analytic tools. Each funded consultancy targets a use case of near-term concern to practitioners. The consultancy featured here focused on improving predictions of asthma exacerbation risk in demographic and geographic subdivisions of the city of Boston, Massachusetts, USA based on the combination of known risk factors for which evidence is routinely available. A cross-disciplinary group of 28 stakeholders attended the consultancy on March 30-31, 2016 at the Boston Public Health Commission. Known asthma exacerbation risk factors are upper respiratory virus transmission, particularly in school-age children, harsh or extreme weather conditions, and poor air quality. Meteorological subject matter experts described availability and usage of data sources representing these risk factors. Modelers presented multiple analytic approaches including mechanistic models, machine learning approaches, simulation techniques, and hybrids. Health department staff and local partners discussed surveillance operations, constraints, and operational system requirements. Attendees valued the direct exchange of information among public health practitioners, system designers, and modelers. Discussion finalized design of an 8-year de-identified dataset of Boston ED patient records for modeling partners who sign a standard data use agreement. |
Sodium intake among US school-aged children: National Health and Nutrition Examination Survey, 2011-2012
Quader ZS , Gillespie C , Sliwa SA , Ahuja JK , Burdg JP , Moshfegh A , Pehrsson PR , Gunn JP , Mugavero K , Cogswell ME . J Acad Nutr Diet 2017 117 (1) 39-47.e5 BACKGROUND: Identifying current major dietary sources of sodium can enhance strategies to reduce excess sodium intake, which occurs among 90% of US school-aged children. OBJECTIVE: To describe major food sources, places obtained, and eating occasions contributing to sodium intake among US school-aged children. DESIGN: Cross-sectional analysis of data from the 2011-2012 National Health and Nutrition Examination Survey. PARTICIPANTS/SETTING: A nationally representative sample of 2,142 US children aged 6 to 18 years who completed a 24-hour dietary recall. MAIN OUTCOME MEASURES: Population proportions of sodium intake from major food categories, places, and eating occasions. STATISTICAL ANALYSES PERFORMED: Statistical analyses accounted for the complex survey design and sampling. Wald F tests and t tests were used to examine differences between subgroups. RESULTS: Average daily sodium intake was highest among adolescents aged 14 to 18 years (3,565+/-120 mg), lowest among girls (2,919+/-74 mg). Little variation was seen in average intakes or the top five sodium contributors by sociodemographic characteristics or weight status. Ten food categories contributed to almost half (48%) of US school-aged children's sodium intake, and included pizza, Mexican-mixed dishes, sandwiches, breads, cold cuts, soups, savory snacks, cheese, plain milk, and poultry. More than 80 food categories contributed to the other half of children's sodium intake. Foods obtained from stores contributed 58% of sodium intake, fast-food/pizza restaurants contributed 16%, and school cafeterias contributed 10%. Thirty-nine percent of sodium intake was consumed at dinner, 31% at lunch, 16% from snacks, and 14% at breakfast. CONCLUSIONS: With the exception of plain milk, which naturally contains sodium, the top 10 food categories contributing to US schoolchildren's sodium intake during 2011-2012 comprised foods in which sodium is added during processing or preparation. Sodium is consumed throughout the day from multiple foods and locations, highlighting the importance of sodium reduction across the US food supply. |
Physical inactivity among adults aged 50 years and older - United States, 2014
Watson KB , Carlson SA , Gunn JP , Galuska DA , O'Connor A , Greenlund KJ , Fulton JE . MMWR Morb Mortal Wkly Rep 2016 65 (36) 954-958 Physical activity can help delay, prevent, or manage many of the chronic diseases for which adults aged ≥50 years are at risk. These diseases can impact the length and quality of life, as well as the long-term ability to live independently. All adults aged ≥50 years, with or without chronic disease, gain health benefits by avoiding inactivity. To examine the prevalence of inactivity by selected demographic characteristics and chronic disease status in mid-life and older adults, CDC analyzed data on adults aged ≥50 years from the 2014 Behavioral Risk Factor Surveillance System (BRFSS). Overall, 27.5% of adults aged ≥50 years reported no physical activity outside of work during the past month. Inactivity prevalence significantly increased with increasing age and was 25.4% among adults aged 50-64 years, 26.9% among those aged 65-74 years, and 35.3% among those aged ≥75 years. Inactivity prevalence was significantly higher among women than men, among Hispanics and non-Hispanic blacks than among non-Hispanic whites, and among adults who reported ever having one or more of seven selected chronic diseases than among those not reporting one. Inactivity prevalence significantly increased with decreasing levels of education and increasing body mass index. To help adults with and without chronic disease start or maintain an active lifestyle, communities can implement evidence-based strategies, such as creating or enhancing access to places for physical activity, designing communities and streets to encourage physical activity, and offering programs that address specific barriers to physical activity. |
Do lower calorie or lower fat foods have more sodium than their regular counterparts?
John KA , Maalouf J , BBarsness C , Yuan K , Cogswell ME , Gunn JP . Nutrients 2016 8 (8) The objective of this study was to compare the sodium content of a regular food and its lower calorie/fat counterpart. Four food categories, among the top 20 contributing the most sodium to the US diet, met the criteria of having the most matches between regular foods and their lower calorie/fat counterparts. A protocol was used to search websites to create a list of "matches", a regular and comparable lower calorie/fat food(s) under each brand. Nutrient information was recorded and analyzed for matches. In total, 283 matches were identified across four food categories: savory snacks (N = 44), cheese (N = 105), salad dressings (N = 90), and soups (N = 44). As expected, foods modified from their regular versions had significantly reduced average fat (total fat and saturated fat) and caloric profiles. Mean sodium content among modified salad dressings and cheeses was on average 8%-12% higher, while sodium content did not change with modification of savory snacks. Modified soups had significantly lower mean sodium content than their regular versions (28%-38%). Consumers trying to maintain a healthy diet should consider that sodium content may vary in foods modified to be lower in calories/fat. |
US consumer attitudes toward sodium in baby and toddler foods
John KA , Cogswell ME , Zhao L , Maalouf J , Gunn JP , Merritt RK . Appetite 2016 103 171-175 Dietary data from a nationally representative survey indicate about 80% of US toddlers aged 1-3 years consume too much dietary sodium, which can influence their preference for salty foods in later life. Information on consumer attitudes can inform strategies to reduce sodium in baby and toddler foods. Data were obtained from a 2012 online survey sent to a sample of 11636 US adults aged ≥18 years enrolled in a national probability-based consumer panel; 6378 completed the survey and had non-missing responses to the question of interest, "It is important for baby and toddler foods to be low in sodium." Prevalence of agreement was estimated. Logistic regression was used to describe associations of respondent characteristics with agreement. The majority of respondents were non-Hispanic white and had a household income ≥$60,000. About 7 in 10 (68%, 95% CI: 66%-70%) respondents agreed it is important for baby or toddler foods to be low in sodium. More than 6 of 10 respondents in most subgroups agreed. Among parents with a child currently aged <2 years (N = 390), 82% agreed (95% CI: 77%-87%); the highest agreement included parents who thought sodium was very harmful to their own health (92%, 95% CI: 85%-99%) or who were watching/reducing their own sodium intake (95%, 95% CI: 90%-100%). After adjusting for sex, age, race-ethnicity, agreement was most strongly associated with being a parent of a child <2 years, thinking sodium was harmful, and watching/reducing sodium intake (adjusted odds ratios ≥ 2.5, 95% CI's not equal1.0). The majority of respondents including most parents agreed it is important for baby and toddler foods to be low in sodium, suggesting wide consumer support for strategies to lower sodium in these foods. |
Trends and determinants of discretionary salt use: National Health and Nutrition Examination Survey 2003-2012
Quader ZS , Patel S , Gillespie C , Cogswell ME , Gunn JP , Perrine CG , Mattes RD , Moshfegh A . Public Health Nutr 2016 19 (12) 1-9 OBJECTIVE: To examine temporal trends and determinants of discretionary salt use in the USA. DESIGN: Multiple logistic regression was used to assess temporal trends in discretionary salt use at the table and during home cooking/preparation, adjusting for demographic characteristics, using data from the National Health and Nutrition Examination Survey 2003-2012. Prevalence and determinants of discretionary salt use in 2009-2012 were also examined. SETTING: Participants answered salt use questions after completing a 24 h dietary recall in a mobile examination centre. SUBJECTS: Nationally representative sample of non-institutionalized US children and adults, aged ≥2 years. RESULTS: From 2003 to 2012, the proportion of the population who reported using salt 'very often' declined; from 18 % to 12 % for use at the table (P<0.01) and from 42 % to 37 % during home cooking (P<0.02). While one-third of the population reported never adding salt at the table, most used it during home cooking/preparation (93 %). Use of discretionary salt was least commonly reported among young children and older adults and demographic and health subgroups at risk of CVD. CONCLUSIONS: While most people reported using salt during home cooking/preparation, a minority reported use at the table. Reported 'very often' discretionary salt use has declined. That discretionary salt use is less common among those at risk of CVD suggests awareness of messages to limit Na intake. |
Sodium content of popular commercially processed and restaurant foods in the United States
Ahuja JKC , Wasswa-Kintu S , Haytowitz DB , Daniel M , Thomas R , Showell B , Nickle M , Roseland JM , Gunn J , Cogswell M , Pehrsson PR . Prev Med Rep 2015 2 962-967 PURPOSE: The purpose of this study was to provide baseline estimates of sodium levels in 125 popular, sodium-contributing, commercially processed and restaurant foods in the U.S., to assess future changes as manufacturers reformulate foods. METHODS: In 2010-2013, we obtained ~ 5200 sample units from up to 12 locations and analyzed 1654 composites for sodium and related nutrients (potassium, total dietary fiber, total and saturated fat, and total sugar), as part of the U.S. Department of Agriculture-led sodium-monitoring program. We determined sodium content as mg/100 g, mg/serving, and mg/kcal and compared them against U.S. Food and Drug Administration's (FDA) sodium limits for "low" and "healthy" claims and to the optimal sodium level of < 1.1 mg/kcal, extrapolating from the Healthy Eating Index-2010. RESULTS: Results from this study represent the baseline nutrient values to use in assessing future changes as foods are reformulated for sodium reduction. Sodium levels in over half (69 of 125) of the foods, including all main dishes and most Sentinel Foods from fast-food outlets or restaurants (29 of 33 foods), exceeded the FDA sodium limit for using the claim "healthy". Only 13 of 125 foods had sodium values below 1.1 mg/kcal. We observed a wide range of sodium content among similar food types and brands. CONCLUSIONS: Current sodium levels in commercially processed and restaurant foods in the U.S. are high and variable. Targeted benchmarks and increased awareness of high sodium content and variability in foods would support reduction of sodium intakes in the U.S. |
